This research aimed to investigate the key factors affecting student satisfaction and loyalty in selected private universities in Cambodia. The study implemented a quantitative survey designed and guided by seven hypotheses to test the causal relationships among variables, such as academic experience, faculty services, campus life, social integration, student support facilities, student satisfaction, university image, and student loyalty. The research applied a multi-stage sampling technique of probability procedures to guarantee the presence of the research population. Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM) were applied for data analysis to test the hypotheses model. The collected survey totaled 543 from three universities. The purposive sampling methods were used to select the three target universities, based on their reputation, the number of students, year of establishment, and the recognition from the Ministry of Education, Youth, and Sport. The stratified random sampling method was employed to select target respondents for data collection by dividing the population into subgroups to ensure a random sample. The results showed that student support facilities, campus life, and social integration, faculty services, and university image play very important roles in the satisfaction and loyalty of the students in three universities.

Most leadership styles are generally designed to enhance the cognitive and behavioral skills of leaders with the implicit assumption that this would ultimately translate into high performance. As we are moving towards Industry 4.0, organizations must employ leadership styles that will help the organization succeed. Thus, the objective of this paper is to confirm the determinant factors for Fourth Industrial Revolution (4IR) leadership attributes in Malaysian manufacturing companies. Stratified sampling was used to select the sample. Data was collected using the online survey method, where the response rate was 43 percent. The respondents consisted of respondents aged from 31-40 years old, with 69 respondents. In terms of race, the highest number of respondents are the Malays. Questionnaires were distributed to middle and top-level managers from manufacturing companies which were listed in the Federation of Malaysian Manufacturers (FMM). Confirmatory Factor Analysis (CFA) was used to confirm the reliability and validity of the construct. Based on the analysis, 66 items could be used to measure the 4IR leadership attributes. The validation of 4IR leadership can also provide predictive implications on improving leaders' performance, given the different attributes confirmed by the findings.

Purpose: This study aimed to investigate the association between obesity and high-sensitivity C-reactive protein (hs-CRP) levels in Korean adults without cardiovascular disease (CVD). Methods: The subjects were 3,634 adults, and data were extracted from the seventh Korea National Health and Nutrition Examination Survey (KNHANES VII-3). A complex sampling design analysis was applied to reflect the stratified and clustered weights. The data were analyzed using the complex sample Rao-Scott chi-square test and multiple logistic regression analysis (in SPSS for Windows version 26.0). Obesity, according to body mass index (BMI), was defined as obesity (BMI = 25-29.9 kg/m²), high obesity (BMI = 30-34.9 kg/m²), and super-high obesity (BMI ≥ 35 kg/m²), and abdominal obesity (AO) was defined as a waist circumference (WC) ≥ 90 cm in males and WC ≥ 85 cm in females. Results: The odds ratios for moderate CVD risk (hs-CRP; 1-3 mg/dL) were 2.21, 4.16, and 7.13 in the obesity, high obesity, and super-high obesity groups, respectively, compared to the normal BMI group. The odds ratio for moderate CVD risk was 2.18 in males with AO and 1.88 in females with AO. The odds ratios for high CVD risk (hs-CRP > 3 mg/L) were 4.40 and 17.55 in the high obesity and super-high obesity groups, respectively, compared to the normal BMI group. Conclusion: This study provides evidence that early detection and prevention programs for CVD should include obesity-related interventions aiming to modulate hs-CRP.

This study empirically examined the moderated mediation effect of volunteer time in the effect of school maladjustment on juvenile delinquency through depression as negative emotions. For empirical confirmation, 7,052 individuals were collected by stratified multi-stage cluster sampling among 4th to 6th grade elementary school, 1st to 3rd grade junior high school, and 1st to 3rd grade high school students in May 2015. This data was used for analysis. The results of the analysis are as follows. First, school maladjustment directly affects juvenile delinquency and indirectly influences juvenile delinquency through depression. In other words, the higher the school maladjustment, the higher the juvenile delinquency. Also, the higher the school maladjustment, the higher the depression, and the higher the depression, the higher the juvenile delinquency. Second, the volunteer time has a significant effect on juvenile delinquency through interaction with the depression. In other words, it was proved that the moderated mediation effect of volunteer time in the effect of school maladjustment on juvenile delinquency through depression as negative emotions. Based on this, policy implications were examined.

Purpose: This study compared health behaviors and health-related clinical characteristics between individuals with normal glucose levels without diabetes and those with undiagnosed diabetes. Factors that were associated with undiagnosed diabetes were identified by sex. Methods: This was an observational study with a cross-sectional design based on data from the eighth Korea National Health and Nutrition Examination Survey, which used a stratified, multi-stage, cluster-sampling design to obtain a nationally representative sample. Multiple logistic regression analysis was employed to compute the odds ratios of health behaviors and clinical characteristics to identify risk factors for undiagnosed diabetes. Results: The overall prevalence of undiagnosed diabetes was 5.2% (weighted %, n = 700, p < .001). Among individuals with undiagnosed diabetes, 58.3% were men. Univariate logistic regression for undiagnosed diabetes identified sex, age, house income, educational level, and triglycerides as influencing factors. In multiple logistic regression by sex, the factors associated with undiagnosed diabetes in men were age, perceived health status, a diagnosis of angina, and triglycerides. Conclusion: Strategies should be targeted to improve health behaviors and clinical characteristics for specific age groups, men in bad perceived health status, women with high systolic blood pressure, and high triglycerides. Moreover, healthcare providers should understand the barriers to health behaviors and health-related quality of life to effectively deliver healthcare services.

Facies analysis of the Late Triassic Hajo Formation, the lowest stratigraphic unit in the Chungnam Basin, shows that the lower part is composed mainly of breccias or conglomerates; the middle part, conglomerates; and the upper part, conglomerates and sandstones. The formation consists of 13 facies, which include horizontally stratified clastsupported conglomerate, clast-supported massive breccia, matrix-supported massive breccia or conglomerate, matrixsupported graded conglomerate, massive pebbly sandstone, horizontally laminated sandstone, massive sandstone, graded sandstone, inversely graded sandstone, planar cross-bedded sandstone, trough cross-bedded sandstone, low angle crossbedded sandstone, and massive mudstone. These are grouped into 4 facies associations (FA). FA I consisted of clastsupported and matrix-supported massive breccias presumably deposited in the talus or upper fan delta environment. FA II consists of matrix-supported massive conglomerate and horizontally stratified clast-supported conglomerate of cobble size and it seems to have been deposited in the upper fan delta environment. FAIII consisted of matrix-supported massive conglomerate of pebble size, horizontally laminated sandstone and massive sandstone may have been deposited in the middle fan delta environment. FAIV consists of massive pebbly sandstone, horizontally laminated sandstone and massive sandstone and presumably was deposited in the lower fan delta environment. In general the Hajo Formation is interpreted to have been deposited at the talus/upper fan delta environment in early stage; it might have been deposited in the alternating environments of upper and middle fan delta in middle stage; and it seems to have been deposited in alternating environments of middle and lower fan delta in late stage.

Objectives : The 3rd community health plan let health centers select and promote core projects considering budget and manpower. This study analyzed the content and selection processes of core projects, using the nationwide 3rd community health plans, to give relevant information on health center policies. Methods : Classification criteria for content analysis of core projects were established and verified through a literature review and by specialist discussions. Fifty plans were selected by stratified proportional random sampling for regional characteristics. And coding criteria standardized through coding repetition and discussion, by 2 persons (k>0.7). Using stratified proportional random sampling for 16 cities and provinces, regional characteristics, 117 plans were selected, and the contents of the core project selection processes and program contents analyzed. Results : The survey was used by 59.8 % of samples as a core project decision-making method. The partici- pants included 98.6, 81.4, 40 and 38.6% of the health staffs, residents, medical institutions, and administrators, respectively. Discussion was used by 15.4% of samples. The participants were health staffs by 100% as a great. The ranking of the frequencies of the selected core projects were, in order; chronic disease control, health promotion, elderly health, maternal-child health, and oral health at 16.4, 14.8, 14.3, 12.7 and 11.9%, respectively. Analyses on the chronic disease control and elderly health contents showed the diversity of object disease, high rates of visitors on patient detection programs, high rates of unclear target populations, and the provision of medical exams and treatments as the main services, with high variations in business per-formance. The national health budgets for health centers in 2003 were about 910 and 240 million won for chronic disease control and elderly health, respectively, which were less than for the other five priority core projects. Conclusions : The chronic disease control and elderly health at the health centers were not standardized for object disease, patient detection program, target population, service provision, and national support budget was insufficient. Thus it is necessary to develop standard guidelines, and increase financial support, for chronic disease control and elderly health

When a heavy rain brings flooding, a high turbid water is flowing into a reservoir. In this study, the effectiveness of the intake structures for the selective withdrawal from the various levels of a stratified reservoir was evaluated by the field experiments and the numerical modeling of the three-dimensional approaching flows. The temperature, the turbidity, and the velocity fields for the selective withdrawal were measured using both YSI6600EDS and YSI6600ADV, respectively. A threedimensional model, FLOW-3D, was used to predict the performance of the intake tower in Imha reservoir. The comparisons of the vertical velocity field showed a good agreement with the field measurements. The efficiency of the turbid-water elimination of the selective withdrawal method from low levels was higher up to 46% than that of the surface withdrawal. From the analysis of the numerical simulation, the efficiency of turbidity elimination increased by 10% for the selective withdrawal from middle levels, and by 30% from low levels. These results showed that the selective withdrawals from middle and low levels are more effective than the surface-water intake. The similar results were obtained by the one-dimensional model, SELECT, which is much more computationally time-efficient.

The purpose of this study was to study the Relationships between Sport for All Participation and Physical and Mental Function affecting the Elderly's Self-perceived Health. For accomplishing this purpose of this study, the 308 subjects were selected by the multi-stage stratified cluster sampling method from the Seoul, in the years of 2008. presently. Out of the 360 questionnaires responded to, only 308 were used for data analysis because 52 were responded to incompletely or incorrectly. The survey questionaries were used to collect data. The questionary for physical function state were developed and standardized by kung-hee chung(1993), yang-lae Kim(2005). And mental function state were divided two parts; self-perceived scale and depress scale. The questionary for self-perceived scale were based on MMSE-K(Mini Mental State Examination-Korea). The questionary for Depression were based on Depression Scale developed by Beck(1978), adapted in Korean and standardization by Lee Young-ho & Song Jong-yong(1991), regulated by Jo Gyu-whang(2004). From the analysis of this study, the following conclusions were obtained: First, according to the elderly people's participation in leisure sport activities, it partially affected physical and mental function state. Second, according to the degree of elderly people's participation in leisure sport activities, it partially affected physical and mental function state.
