    (Mahidol University. Mahidol University Library and Knowledge Center, 2016) Tam Jatunam; Teeradej Chai-Aroon; Pimpa Kachondham; Pairuch Borvornsompong
    The purpose of this research was to examine the current support services available for students with visual impairment, the essential needs to support the students with visual impairment as well as the policies in supporting students with visual impairment in the model higher education institutions. The research participants consisted of 227 students with visual impairment, 46 Members of staff, and 5 university administrators. The research instruments included two sets of questionnaires: one for students with visual impairment and another for the staff, and a interview schedule for university administrators. For data analysis procedure, descriptive statistics were used in analyzing general quantitative data, cluster analysis employed in categorizing the participants into three groups, while content analysis and coding approaches were performed in examining qualitative data. The findings showed that: (1) The current support services available for students with visual impairment could be classified into three groups: high support system (HSS) medium support system (MSS) and low support system (LSS) capability to accept students with visual impairment. All three groups had high capability to provide financial and social support, and had medium capability to provide friendly physical environment. (2) Students with visual impairment had five essential needs and were able to access support services in five domains including social support, financial support, friendly physical environment, testing accommodation, and general support from staff. (3) Regarding policies, the university administrators had approved the policies of the Higher Education Commission by establishing the disability support service centers, and disability support services were included as a part of educational quality assurance of the universities.

    (Mahidol University. Mahidol University Library and Knowledge Center, 2024) Tadsaneewan Gantagad; Siriorn Sindhu; Chukiat Viwatwongkasem; Ketsarin Utriyaprasit
    Chronic kidney disease usually causes a decline in kidney function and results end stage renal disease. The objective of the study consisted of determining the incidence of faster kidney disease progression and determining factors affecting on kidney disease progression among patients with chronic kidney disease. The samples in this study included 2,185 patients' medical records, and 360 patients with chronic kidney disease who visited outpatient clinic in eight hospitals located in one of the health area and Bangkok Metropolitan administration area. The results showed the incidence of faster kidney disease progression was 13.12 per 100 persons-years. The predicting factors of faster kidney disease progression were CKD knowledge 0.54 (95% CI 0.43 - 0.72, p < .01), self-management ability 0.79 (95% CI 0.71-0.88, p < .01), self-management support 0.12 (95% CI 0.06-0.25, p < .01). The paths of factors affecting kidney disease progression included CKD knowledge (β = 0.11, p < .001), self-management support were significant (β = 0.03, p < .001), path from the CKD knowledge to kidney disease progression were significant (β = -0.19, p < 0.05), path from self-management to kidney disease progression were significant (β = -0.15, p < .001). The results of the testing revealed Chi-square (χ2) = 2.06, df = 1, p = 0.15, RMSEA = 0.05, NFI = 0.98. The study result imply that health care provider including nurse may enhance the success of delaying the kidney function decline by providing CKD knowledge and self-management support. In addition, human resource allocation is necessary for health service system in both of quantity and quality of provider.

    Buddhist-catholic relations in Thailand : 'Dialogue of life' of Bangkok Catholics towards Buddhists
    (Mahidol University. Mahidol University Library and Knowledge Center, 2019) Francis Chan Sze Ming, 1966-; Hubina, Milos; Kosuta, Matthew; Esteve, Julia
    This research was done to study attitudes of Bangkok Catholics toward Buddhists and how dialogue of life is manifested in the bigger context of Buddhist-Catholic relations in Thailand. The theoretical background and framework looked into some modern theories of dialogue, then examined Christian attitudes toward people of other religions through theology of religions. Various Vatican II and post-Vatican II documents were studied to help understand the official Church position, and the history of Buddhist-Catholic relations in Thailand were looked into to better appreciate the present situation of the relations. In-depth interviews were carried out with 29 subjects, 25 of whom were Catholics, to examine the Catholics' attitudes, positions, and views toward Buddhism and Thai Buddhists. It was found that the majority of the Catholics had an attitude of pluralism, and they adhered to official Church directives regarding evangelization and dialogue whenever these were practical and conducive for maintaining societal peace and harmony. Also, it was found that the Catholics had largely appropriated popular Thai Buddhist religious terminology and concepts, though not necessarily imbibing their full Buddhist meanings. Furthermore, it was also revealed that the friendship factor and avoidance of controversies were important aspects in the Catholics' relations with Buddhists, and the main aspect of dialoguing with Buddhists was ordinary living together, or dialogue of life. This study showed the significance of how a tiny minority Asian Church has adapted and assimilated to a dominant Buddhist majority sociocultural, politically, and even theologically.

    Prevalence and distribution pattern of mood swings in Thai youth : school-based survey
    (Mahidol University. Mahidol University Library and Knowledge Center, 2024) Suleemas Angsukiattitavorn; Acharaporn Seeherunwong; Mathuros Tipayamongkholgul; Rungnapa Panitrat
    Mood Swings (MS) is a common feature widely discussed as a prodromal sub-symptom of mental problems and psychopathology. However, there is paucity of knowledge related MS. This school-based, cross-sectional study aimed to investigate the prevalence and distribution pattern of mood swings on personal determinants and contextual determinants among Thai youth. Questionnaires were provided by using smartphone to determine demographic data, personal determinants: family history of mental problems, bullying involvement, social media use, and substance use and contextual determinants: family structure and circumstance and school location. The participants were students (2,598) in high schools (1,382) and vocational schools (1,216) in Bangkok and central region of Thailand. Multi-stage stratified random sampling and the classroom cluster were used to determine the sample size. Analysis of variance, odd ratio, and hierarchical multiple logistic regression models were used for analysis. Results showed the prevalence of mood swings was 26.4%. It was most frequent among students in the vocational schools in Bangkok area (37.1%). The bivariate analysis showed a significance difference of distribution of MS on personal and contextual determinants. The distribution of MS could be found in adolescents who had risk behavior and residing in hazardous situation. The probabilities of MS in aged 15 - 24 years were: bullying involvement 36.9% (n=1,293), problematic social media use 55.9%(n=127), high expressed emotion in family 36.6%(n=1,256), and studying in vocational program 29.5%(n=1,216) and school located in Bangkok 32.4%(n=561). Also, substance use was probably a risk to MS such as cannabis 41.8%(n=55) and heroin 48.0%(n=25). In addition, the current study found significant hierarchical logistic regression analysis of female, family history of mental problems and illness, bullying involvement, problematic social media use, illicit substance use, high expressed emotion in family. Finally, an interaction between vocational program and metropolitan/ urban area impacted on mood swings (p < .05) when all included variables were controlled. The final model showed acceptable fit (X 2 =398.53, df=20, p=.106). Findings of the study indicate that the pattern of mood swings was associated with significant bullying involvement, problematic social media use, illicit substance use, family circumstance and school characteristics. The public need greater awareness of mood swings pattern and its alternative implications of MS screening. Moreover, early intervention for prevention of mental illness is needed.

    A corpus-based study of antonym sequence in Japanese
    (Mahidol University. Mahidol University Library and Knowledge Center, 2018) Phornthip Nithithanawiwat; Isara Choosri; Pattama Patpong
    A corpus-based study of antonym sequencing in Japanese aimed: (1) to investigate antonym sequencing when co-occurring in one sentence; (2) to investigate the factors affecting antonym sequencing; (3) to examine whether the preferred ordering within antonym pairs is determined by frequency or not. This study tested 2 hypotheses. First, different frequency patterns of the order within antonym pairs in antonym sequences in Japanese follow the markedness principle; Second, more frequently used antonyms of antonym pairs occur more frequently in the preferred position within antonym sequences in Japanese. The data was collected from Tsukuba Web Corpus, and the test hypothesis regarding population proportion was used for the test statistic. The collected antonymous pairs were ordered according to predictive markedness properties, and they were tested by population proportion. The 131 antonym pairs (69 percent from total 191 pairs) which had p value below 0.05 may support the first hypothesis, that different frequency patterns of the ordered antonym pairs in antonym sequences in Japanese follow the principle of markedness. It was found that 7 factors based on the principle of markedness influenced sequencing, namely positivity, phonology, morphology, magnitude, chronology, spatial position and culture-specific factor. The later consists of yin-yang principle which is based on Chinese philosophy, uchi-soto and seniority. These three exist in the socio-cultural fabric of Japan. Uchi-soto notion is unique character of Japanese culture. It is reflected in real language use and appears in antonym sequencing such as kokunai 'domestic' prcedes kokusai 'international by 72%. It seems to provide priority of relationship with Japan (as uchi 'inside') more than other countries (as soto 'outside') following uchi-soto notion. Moreover, the word frequency influenced the preferred ordering of 85 antonym pairs in Japanese by 65 percent (from total 131 pairs), and it may be sufficient evidence to support the second hypothesis, that more frequently-used antonyms of antonym pairs occur more frequently in their preferred position within antonym sequences when co-occurring in one sentence in Japanese.

    (Mahidol University. Mahidol University Library and Knowledge Center, 2024) Nicha Chansitthichok; Anak Charanyananda; Narongchai Pidokrajt; Treetip Boonyam; Pansak Polsaram
    The music teacher training project supported by the government operates annually with restricted training contents, and shallow understanding of characteristics of music content leading to a limitation in music teacher development. This research aims to (1) explore the current status and structure of music teacher training, (2) construct a model of music teacher training for lifelong learning skills, and (3) develop the trainer's manual of music teacher training as a path to lifelong learning skills. This qualitative research collected data by interviewing 40 samples including music teachers, music trainers and music educators who were involved in music teacher training in 2017-2018, and observing music teacher training exercises. The result of this research found similarity in the type of training courses which mostly are set as a single training course with no continuity to higher level training. The observation and interview data were analyzed for creating the music teacher training model. The model consists of three parts (1) input information: training type, participants, course output, course content, and assessment (2) designing training process: the activities and details in training process, and (3) output: developing lifelong learning competencies

    (Mahidol University. Mahidol University Library and Knowledge Center, 2024) Napaphat Poprom; Ammarin Thakkinstian; Sasivimol Rattanasiri; Chumpon Wilasrusmee; Oraluck Pattanaprateep
    Appendicitis is the most common abdominal urgent condition in general surgical practice. Although appendectomy was a gold standard treatment management, its procedure was associated with post-operative complications and new instruments and technologies have been launched over times. Recently, conservative treatments with antibiotics have been studied and considered as an alternative choice for uncomplicated appendicitis and individual antibiotics might have more cost-utility than appendectomy either laparoscopic appendectomy (LA) or open appendectomy (OA). Therefore, this study was conducted to provide evidence and information aiding decision making to prescribe antibiotic treatment or surgical treatment for uncomplicated acute appendicitis. Objectives: 1) To assess and compare rates of success and overall major complications between LA and OA, 2) To estimate health-related quality of life (HRQoL) among antibiotic treatment and surgical treatment within one year due to the intervention, and 3) To perform cost-utility to estimate incremental cost-effectiveness ratio (ICER) among individual antibiotics, LA and in uncomplicated acute appendicitis. Methods: For the first objective, an umbrella review of meta-analyses (MAs) was performed with update MAs to assess and compare rates of success and overall major complications between LA and OA. MAs were identified from PubMed and Scopus databases published from Jan 1990 to July, 2018. The fixed or random effect model was applied to the pool treatment effects. For the second objective, a cohort study was conducted to estimate HRQoL among the antibiotic treatment and operative treatment at Ramathibodi Hospital. The EQ5D-5L was applied to HRQoL, For last objective, the cohort study was applied to collect the direct non-medical cost, and indirect cost and a retrospective study was applied for direct cost from November 2018 to October 2019. To perform cost-utility by an ICER among the individual antibiotics and surgical treatment in uncomplicated acute appendicitis, the Tornado diagram was plotted to report which of one-way sensitivity analyses should be applied. Results: Ten MAs were eligible; surgical site infection (SSI) was reported in all MAs and intra-abdominal abscess (IAA) in 8 MAs. SSI rate was 48% to 70% lower in LA than OA, but conversely IAA rate was 1.34 to 2.20 higher in LA than OA. The risk ratios (RRs) (95% CI) comparing LA vs OA were re-pooled in adults and children yielding RRs of 0.56 (0.47, 0.67) and 0.40 (0.25, 0.65) for SSI; and 1.20 (0.88, 1.63) and 1.05 (0.61, 1.80) for IAA. After estimated by treatment model the results showed antibiotics treatments were higher than surgical treatment especially in beta-lactamase with 0.97 (0.94, 0.99) which was significantly higher difference compared with OA. CUA was performed to estimate ICER among individual antibiotics (beta-lactamase, quinolone, and 3rd generation of cephalosporin+metronidazole), LA, and OA in uncomplicated acute appendicitis. This aimed to compare antibiotics treatment and surgical treatment and indicated an ICER -304,229.79 Baht per utility gained. Conclusion: The antibiotics treatment suggested more utility score with the trend to use the lower cost of treatment rather than the surgical treatment in the uncomplicated acute appendicitis patients. Therefore, the antibiotics treatment should be considered for the alternative choice for the patients to decrease the complication rate from the surgical treatment.

    (Mahidol University. Mahidol University Library and Knowledge Center, 2024) Sirilak Pongchoke; Srisombat Chokprajakchat; Nathee Chitsawang; Theerat Bunnag
    This mixed-method study entitled "Developing aftercare treatment for the newly released female inmates in Thailand" aims to 1) find out the problem and impediment of the present operation, the needs of the newly released female inmates, and the factors affecting the achievement of the rehabilitation programs of Department of Corrections, 2) improve the treatment system towards the newly released female inmates and develop the appropriate aftercare treatment for the newly released female inmates. The documents, indepth interview, focus group, and questionnaire were utilized in data collection from those executives of Department of Corrections and Department of Probation and the scholars in the total of 10. The in-depth interview was still conducted with 3 newly released female inmates and the focus group was conducted with 15 operators of Department of Corrections while the questionnaire were answered by 280 female inmates who are going to be released. From the study, it is revealed that the government has the policy in taking care of as well as rehabilitating the newly released female inmates through the operation approach based on the integration of networks and a social sector in order to monitor and favor those newly released female inmates in the 2017 - 2021 fiscal year. They also have the correcting, rehabilitating, monitoring, assisting measures for the offenders in the community at the office level. In addition, they still have the Phiboon Songkhroh foundation functioning in helping the newly released female inmates under the supervision of Department of Correction administration. Nonetheless, the problems that Department of Corrections are facing start from screening, assessing, and rehabilitating the inmates. These are the consequences of the inmate overflow of the prison. Apart from this, the problem in concretely monitoring and assessing the newly released female inmates is still found in the study.

    The development of labour relations system for promotion of good governance in human resource management of public higher education institutions
    (Mahidol University. Mahidol University Library and Knowledge Center, 2024) Aree Phasansinthuwong; Chokchai Suttawet; Siriporn Yamnill; Jitlada Amornwatana
    The objectives of this research were to study the development and the issues on labour relations system and relationship with human resource management of public higher education institutions, to search for the best practices and outstanding guidelines on labour relations in public sector, as well as to seek a suitable system in promoting good governance in such public higher education institutions area, including recommendation for developing the labour relations system to promote good governance in the human resource management. This study was conducted as Mixed Method Research with Concurrent Embedded Strategy that mainly emphasized on qualitative data coupled with quantitative data. Qualitative data was gathered through the study of documents and indepth interviews with 58 informants and a focus group discussion with 7 participants. As for the quantitative data, Purposive Sampling was conducted among 83 higher education institutions, and a questionnaire was used to collect the data. The findings showed that the development and issues of labour relations and its relationship to human resource management of public higher education institutions is in a seriously unqualified situation to good governance, inhibiting from a coverage of industrial relations law, and including the differences in fundamental idea of labour relations system practicing in public higher education institutions. The pattern and best practice guideline to promote good governance in such matter, comprises two key mechanisms, namely, Joint Consultation System by setting up of a Joint Consultation Committee of the University staff and Management representatives as compared to the trade union role in a company's consultation body. The success factors of promoting the compatibility of the labour relations system and human resource management, are consisted of political, cultural, organizational, economic, technological, organizational factors, and the influence of the International Labour Organizations's standards. However, the leadership factors and a political support have been mentioned more than the other factors. Regarding the development on labour relations system to promote good governance and policies, the State should review Labour Relations Laws to ensure the rights of all University employees and other employed workers. There should be the announcement of policy on measures promoting an integration of labour relations at organizational and national levels to connect labour relations with good governance on human resource management. Regarding the practical level, the agencies for managing labour relations should be established as well as promoting the roles of Lecturers and Staff Council as a workers' democratic organization, to negotiate and consult with the management.

    The effectiveness of integrated budgeting management for fighting corruption
    (Mahidol University. Mahidol University Library and Knowledge Center, 2018) Mingkwan Chiruppapha; Somboon Sirisunhirun; Krish Rugchatjaroen; Somsak Amornsiriphong; Chokchai Suttawet
    This research aimed to 1) study the existing problems during public sector operation to prevent and suppress corruption and misconduct, 2) analyze factors leading to effectiveness, and 3) investigate appropriate direction to manage budget. The research emphasizing qualitative approach employed 55 key informants who were involved with integrated budget management and anticorruption matters. The research instruments were in-depth interview (IOC = 0.84), the Delphi technique questionnaires (IOC = 0.97), and the record form of the focus group (IOC = 0.79). The instrument quality validation was checked through the content validity and the Index of Item Objective Congruence (IOC) values. The research findings revealed that the problems occurred within division which is ineffective anti-corruption tool were due to the negligence of organization leader, no enforcement on preventive measures or no serious disciplinary action to strengthen internal audit, and lack of moral atmosphere and good governance. Also, human resource management frequently applied a patronage system based on favoritism, whereas true value and ethics has not been embedded under the Merit System so that those who seized opportunity for personal gain or career advancement would allow themselves to foster crooked policies and facilitate corrupt transaction. Politics, management, resources, and good governance led to effectiveness in budgeting management, which coincided with John P. Campbell's 19 criteria: overview efficiency, effectiveness, quality, job performance satisfaction, motivation, morale, control, conflict, unity, stability, involvement and decentralization, highlight successes, plan and targeting, objective consensus, understanding organization purposes, consistency between role and norms, skill in human resource management, work management, managing information and communication, and readiness. The Integrated Budget Management should apply the mechanism tactic of "Team Thailand Anti-Corruption 4.0" with understanding, synergy and sincerity. The use of CPS (cultivate prevention-suppression) or the practice of 3Cs (cultivate-counter-conquer) with sharing resources between 2 divisions and more to deliver outputs in the form of value chain at upstream-midstream and downstream must be acknowledged. Also, the National Committee must oversee the operation with permanent management structure. CEOs (Chief Executive Officer) must adopt the concept on the integrated management routine to consistent work rather than ad hoc missions. NACC should be the hosts in supervising and aligning with the AOCs (Anti-Corruption Operation Centers) between Agenda/Function/Area Based (ministries, department, agencies in the regions, provinces, provincial groups, zones, and local government) in order to reach the expected outcomes in alignment with the indicators of integrated budgeting plan with more concrete and practical manual

    The development of an Intelligent Travel Technology Assessment Model (ITTAM)
    (Mahidol University. Mahidol University Library and Knowledge Center, 2019) Noppadol Phaosathianphan; Adisorn Leelasantitham; Supaporn Kiattisin; Taweesak Samanchuen
    The objective of this study was to develop an assessment model of intelligent travel technology which includes two groups of antecedent variables, namely external factors (Ease of Use, Trust, Enjoyment, Design) and belief factors (Usefulness, Quality, Safety and Empathy), and two groups of psychology variables, namely function factors (Pre-Trip, On- Route, On-Site and Post-Trip) and feeling factors (Satisfaction and Intention to Use). These factors would influence the user acceptance and perception of destination impacts that include three variables, namely Competitiveness, Loyalty and Sustainability. According to an indepth review, essential theories include travel, tourism, VPA, IPA, AI, IoT, DIT, TAM, UTAUT, IS Success Model, IS Continuance Model, Human-Computer Interaction, Socio- Technical System and so on. These theories were used to formulate the research model then transformed it into the research hypothesizes and produced an online questionnaire that was surveyed via social media platforms such as Facebook and Line. The collected data was 400 voluntary respondents which were analysed with descriptive statistics such as percentage and standard deviation (S.D.) by PASW Statistics v.18.0.0 and inferential statistics such as measurement model and structural model by SmartPLS v.3.2.8. Therefore, this study aids in understanding the factors and psychology process influencing user acceptance and perception toward destination impacts of using intelligent travel technology. Finally, the results of this research could apply to design and implementation of intelligent travel technology, and also thoroughly assess the technology acceptance and perception of destination impacts.

    A discourse study of community justice policy implementation under the policy mottos Justice for All, All for Justice and Justice to All, All to Justice
    (Mahidol University. Mahidol University Library and Knowledge Center, 2024) Chatchai Mangkornsangkaew; Chokchai Suttawet; Somboon Sirisunhirun; Srisombat Chokprajakchat
    The purpose of this study was three-fold. Firstly, it aimed to study and analyze community justice policy implementation under "Justice for All, All for Justice" and "Justice to All, All to Justice". Secondly, it aimed is to understand the very meaning of those discourses above in community justice policy. The last objective was to study the result of discourse to policy implementation and to forensic use of national identification in community justice policy. The data were gathered from relevant documents, policies, questionnaire survey, in-depth interviews, and focus group discussion from upper-level administrative officer (1), scholarly expert (1), general-directors (2), heads of unit (2), non-government officers (3), directors of division (5), and justice provincial officers (131).Critical discourse analysis was chiefly employed for data analysis. The research results revealed that the implementation of community justice policy under "Justice for All, All for Justice" and "Justice to All, All to Justice" apparently instigated not only the use of top-down approach "Administrative justice to people", very frequently but also bottom-up approach as "Access to justice of people" less frequently. The meaning of the discourse in general is the same. However, in the case of content, the very meaning of "Justice to All, All to Justice" is more emphasized on reduced social gap than "Justice for All, All for Justice". It could be implied that "Justice for All, All for Justice" is related to top-down approach, whereas, "Justice to All, All to Justice" is related to bottom-up approach. At present, both of bottom-up and top-down approach, top-down, and bottom-up approach could be seen in rank-order, respectively. The resultant of discourse to community justice policy implementation and forensic uses of national identification showed that "Justice to All, All to Justice" is a way for justice ministers and politicians to get into locale to cultivate justice perception to people which is different from "Justice for All", All for Justice" which emphasized on perception of government officers. As a result, the very meaning of both discourses are the same, and the effect to policy implementation is little. Likewise, there are no effects of forensic uses of national identification on community justice policy.

    Forbush decreases at The Princess Sirindhorn neutron monitor and the leader fraction
    (Mahidol University. Mahidol University Library and Knowledge Center, 2020) Chanoknan Banglieng; Ruffolo, David John; Rivera, Alejandro Saiz; Kittiwit Matan
    The Princess Sirindron Neutron Monitor (PSNM) with the world's highest geomagnetic cutoff rigidity ~17 GV, was the first fixed station using the specialized electronics to collect time delay histograms for statistically estimating the leader fraction L. Our analysis data period, during 2007 Dec - 2018 Apr 19, covered almost a full 11-year solar cycle. After correcting for pressure and precipitable water vapor in both the leader fraction L as a proxy of the GCR spectral index and count rate C as a measurement of GCR flux above the cutoff rigidity at PSNM's location, we find that L is roughly correlated with C, but also exhibits hysteresis that indicates a change in spectral shape after the change in solar magnetic polarity. These methods enhance the high-precision GCR spectral information from the worldwide NM network and extend it to higher rigidity. A Forbush decrease (FD) is the decrease in count rate as observed by a neutron monitor associated with a solar storm (CME) and/or its shock. The viewing direction of PSNM sometimes observed the pre-Forbush decrease level in events defined as diurnal dips (DDs). We developed criteria to select decreases observed by PSNM as DDs or FDs. Our criteria found 16 DDs and 20 FDs.

    Effects of muscle energy technique in patients with chronic low back pain of zygapophyseal joint origin
    (Mahidol University. Mahidol University Library and Knowledge Center, 2016) Wahyuddin, 1994-; Mantana Vongsirinavarat; Keerin Mekhora; Sunee Bovonsunthonchai
    This study aimed to investigate the immediate effect of muscle energy technique (MET) for individuals with chronic low back pain (LBP) from zygapophyseal joint origin. Twenty-one subjects who met the criteria were recruited. The participants were randomly assigned to receive one session of treatments either MET as experimental group or lumbar stabilization exercises (LSE) as control group. The primary outcome was lumbar spine movements, and secondary outcomes were pain threshold, pain intensity, and disability level. Lumbar active range of motion (AROM) for flexion, extension, right lateral flexion, left lateral flexion, right rotation, and left rotation, and pressure pain threshold (PPT) were evaluated at baseline and immediately after treatment. Visual analogue scale (VAS) was evaluated at baseline, immediately after treatment, and two days after treatment. In addition, Thai version of the modified Oswestry LBP Disability Questionnaire (ODQ) was utilized at baseline and two days after treatment. Independent sample t-test, and two-way repeated measure ANOVA were used for statistical analysis. The results showed significant main effect of time for right lateral flexion, VAS and ODQ scores (p<.001). The time effect of lateral flexion movement might be the result of reflex muscle relaxation after both interventions. Also, the pain and function were improved after both types of physical therapy treatments. The analysis of changed score showed no significant differences for all outcomes. In conclusion, this study revealed the immediate effect of MET and LSE which were effective to increase AROM, decrease pain intensity and disability level. Therefore, the choice or combination of MET and LSE as tailor-made intervention might be more beneficial for individuals with chronic LBP due to zygapophyseal joint problems.

    Public service improvement of industrial waste management and new management approach through net-working for sustainable development
    (Mahidol University. Mahidol University Library and Knowledge Center, 2024) Peerapong Nissapokin; Chokechai Suttawet; Somboon Sirisunhirun; Seree Woraphong; Kanokwan Komonweeraket
    This research is aimed at three main objectives, (1) to study the industrial waste management measurements of advanced countries applying the industrial wastes management principles at the international level, and make a comparison with the domestic standard measurements for the industrial waste management in Thailand, (2) to study the situation in industrial waste management and the problems in the net-working approach of the government sectors and private sectors (factories), both internal and external industrial estate, and (3) to develop a new way of government public service of industrial wastes management among concerned organizations for increasing the efficiency and effectiveness of industrial waste management for continuous sustainable development. The research work is a qualitative -lead quantitative integration kind. The tools of research were in-depth interview, questionnaire and focus group. The used statistics for data analysis are the percentage, mean, and standard deviation. Findings; 1. It was found that the 10 international principles are consisted of 1) Reduction 2) Re-use 3) Recycle 4) Treatment 5) Disposal 6) Sorting 7) Recovery 8) Prevention 9) Storage 10) Energy and material conservation. That not all of those 10 international principles aforementioned were applied for assessment from the private sectors (factories), both inside and outside the industrial estate, gave most use of disposal, and gave least recovery, or showing that it was not emphasized at the main cause or at the original as in many other advanced or progressed industrial countries in the International Standard Level are doing. 2. The Efficiency and effectiveness of the government sectors in wastes management of both inside and outside of the industrial estate, in the Samut Sakhorn Province, including the participation, cooperation and collaboration from the community were at the moderate level, this indicated that the industrial waste management of the government sectors is still needed highly to improve for higher efficiency and effectiveness of services. 3. The new trends in improvement of public service by the government for promoting the net-working approach management should be in setting up or creating committees that work in each zone, district or provincial level, including integration of private sectors (factories), by support from the government, for collection and accumulation of industrial wastes in each of the provincial zones and areas. The project should begin in Samut Sakhon Province.

    Anti-corruption practice in promotion and tranfering in administrative official
    (Mahidol University. Mahidol University Library and Knowledge Center, 2024) Suwat Chansug; Wanaporn Tehagaisiyavanit; Sunee Kanyajit; Kamol Supreyasunthorn; Srisombat Chokprajakchat
    This study was an investigation of the concept of criminological philosophy and penology to help stipulate a criteria of the punishment suspension measures in the Criminal Code, Section 56 for substantial application. This was documentary research that also employed an in-depth interview with judges working in the Trial Court, the Appeals Court, and the Supreme Court. The results revealed that the sentences stipulated were appropriate for the offense and the offenders. The suspension was a measure the court could decide to impose on some types of offenses and for the offenders appropriate to their conditions and their individuality in each case. This was to provide opportunity for the offenders to became good citizens, without criminal records and to deter short-term imprisonment. Most judges, on the contrary, never applied the punishment suspension measures in their judgments but imposed the reprieve. Rationally, most judges reflected on the penalty account and viewed that it was adequate, that the punishment stipulated needed to follow the penalty account and the laws while disregarding other facts such as the defendant's historical records, gravity, and the damages caused by the offense. The judges might have fear of the penalty account had not been followed, they would have to blamed for not aligning with the penalty account; it was then inferred as corruption (if their judgment) Consequently, the judges adhered to the penalty account as the principle of judgment in order to protect themselves and ignored facts to complement their judgment. There should be a standard criteria to enable the judges to impose the punishment suspension measures in their judgments through using the concept of criminological philosophy and penology as guides for the substantial stipulation. The recommendations from the study were; it was necessary to stipulate the criteria of penalty account, offenses should be stipulated in the rate of the penalty account so that the courts could, in the same direction, impose the punishment suspension measures and meet the rule of law. The knowledge and the concept of penology theory should be promoted among the judges.

    Wildlife trafficking is a prolonged crisis of environmental crime in Thailand. The policy of wildlife also regulated without thoughtful studying on the problems. Ineffective law enforcement and corruption of officials regarding wildlife trafficking has become a problem that cause huge damage to Thailand. The negative outcomes therefore led to explore Green Criminology possibly defined the situation and occurrences of wildlife trafficking in Thailand. Including, the policy of protection of suppression in wildlife trafficking in Thailand appeared whether the way to decline wildlife trafficking in Thailand. The methodology was qualitative research. Study on documentary and in-depth interviews was conducted with the key informants who are involved in the prevention and suppression of wildlife trafficking from public agencies, private sectors, academic sector and civil society. The Green Criminology concept can be demonstrated the situation of wildlife trafficking in Thailand because it causes huge damage to humans and society, wildlife, environment and ecosystems. Even though Thailand has policies to protect and suppress wildlife trafficking, however, wildlife trafficking repeatedly occurs in Thailand due to problems on law enforcement, policy and agency and offender. Those were obstacles to the effective implementation of policies. Thus, cooperation among government agencies, private sectors, academic sectors and civil society is required to achieve both proactive and reactive operations in order to reduce problem of wildlife trafficking in Thailand.

    Using momentum vector diagram to teach collision
    (Mahidol University. Mahidol University Library and Knowledge Center, 2019) Trai Unyapoti; Kwan Arayathanitkul; Narumon Emarat; Ratchapak Chitaree
    This study aims to enhance students' understanding and problem-solving skills of collisions. A teaching method called 'Momentum Vector Diagram (MVD) was developed to help students realize the concept of the vector quantity of momentum and to help them solve the collision problem correctly. The effectiveness of the MVD method was compared to the traditional teaching. The MVD was applied to the physics classes at 4 schools during the academic years 2014 to 2017 in the topic of momentum and collision. The pre-test and post-test were used to assess students understanding. The post-test results indicated that the students who studied with the MVD method had a higher average score than the students who studied with the traditional methods (2.42 ± 0.56 vs 1.55 ± 0.45). In the control group, it was found that the number of students who used the MVD method giving correct answer was more than the traditional method (74% vs 53%). In addition, it was found that the class averaged normalized gains were at the low gain for the traditional method ( = 0.26) and at the high gain for the MVD ( = 0.74). It can be concluded that the MVD is more effective in enhancing high-school students problem solving skills in the topic of collision than traditional method.

    The development of public policy and administration on social security in ASEAN : a case study of social insurance for Thai migrant workers
    (Mahidol University. Mahidol University Library and Knowledge Center, 2024) Wilailak Yoosamran; Chokechai Suttawet; Gamolporn Sonsri; Ratthasirin Wangkanond
    The research aimed to study the development of public policy and administration on social security, as well as explore factors affecting the directions and changes in public policy as related to social security for ASEAN migrant workers, including the study of operational conditions and problems of public agencies in charge of social insurance benefits protection for Thai overseas migrant workers in the host countries: Singapore, Malaysia, and Brunei, and lastly develop schemes and guidelines on social insurance benefit protection for such migrants. This study was a mixed-method research employed concurrent procedure of the qualitatively-driven core component coupled with simultaneous QUAL+quan. Qualitative data were collected using in-depth interviews with 55 key informants and 30 Thai migrant workers for focus group discussion. The sample groups of the quantitative research selected by purpose sampling were 275 Thai migrant workers. Research revealed that the development of policy and administration on social security for ASEAN migrant workers had not obviously conducted joint operation between ASEAN member countries. Factors affecting the directions and changes in public policy as related to social security for ASEAN migrant workers comprised of economic, social, political, technological factors and international organization in which technological factor was less mentioned than other factors. Meantime, the operation conditions and problems of agencies in charge of social insurance protection for Thai migrant workers involved numerous limitations, especially on the short-term benefit, including obstacles imposed by different countries. This created inferior treatments for Thai migrant workers as compared to the country own citizens. As for possible schemes and guidelines for social insurance benefit protection for Thai migrant workers, only Thailand measures or the measures of country of origin were most appropriate and likely applied, followed by measures of disputed countries. Nonetheless, bi-lateral measures and ASEAN's multi-country measures were difficult to operate, especially the latter measure is the most difficult because it is imperative to amend laws in each country prior to negotiation and making of long-term agreement.
