  • The study in this paper, which is part of a bigger study investigating non-cognitive characteristics of Korean students at the 4-12 grade levels, aims to identify the influential characteristics that explain students' decision to give up on mathematics learning. We consider seven non-cognitive student characteristics: value, interest, attitudes, external motivation, internal motivation, learning conation and efficacy. Data were collected from 21,485 Korean students, and were analyzed with a logistic regression method using SPSS. The findings show that efficacy was the most significant indicator of students' decision to give up on mathematics learning in all three grade level bands: elementary (4th-6th), middle (7th-9th) and high (10th-12th). In particular, the causal model analysis shows that students who highly value mathematics tend to have stronger internal and external motivation, which bring about stronger interest and learning conation, which in turn lead to positive attitudes and strong efficacy regarding the learning of mathematics. It was further found that while external motivation was a significant indicator of upper grade level students' decision to give up on mathematics learning, it was only a moderate indicator for lower grade level students. The findings of this study provide useful information about which non-cognitive areas need to be focused on, in what grade levels, to help students stay on track and not fall behind in learning mathematics.

  • The purpose of this study was to examine the variables of success in the national dental hygienist licence examination at D college. The subjects in this study were 120 dental hygiene juniors at D college located in Gangwon Province. The collected data were analyzed by the statistical package SPSS WIN 13.0 and a R2.13.2 program, and $x^2$(Chi-square) test, regression analysis, multiple linear regression analysis and logistic regression analysis were utilized. The findings of the study were as follows: 1. There was a tendency that the pass rate was higher among the students who were more satisfied with their major, whose academic standing was higher and who scored higher in trial examinations. 2. There was a positive correlation between academic standing and trial exam scores. 3. When their academic standing and satisfaction level with major were the same, an increase of one point in trial exams led to a 1.141-fold rise in the probability of passing the national exam. In this study, trial exam scores were identified as the variable to exert the largest influence on success in the national dental hygienist qualification exam. Therefore more intensive guidance should be provided for students who make a preparation for the national exam yet score low in trial exams.

  • This study analyses the macroeconomic effects of the direct payment system (DPS) for environment-friendly agriculture in Korea. We utilized the applied general equilibrium model (AGE model) for the general agricultural sector as well as the environmentally-friendly agricultural sector. We considered several scenarios based on various direct payment amounts to measure and analyze economic impacts. Scenario 1 considers the current direct payment system. Scenario 2 examines an additional 5% increase from the direct payment amount in scenario 1. Scenario 3 reviews an increase of 10% in direct payment amount while Scenario 4 considers an additional increase of 15% compared with Scenario 1. Lastly, scenario 5 examines a 20% increase in direct payment amounts compared with scenario 1. In addition, the baseline considers conditions prior to the introduction of the direct payment system. The simulation analysis results show that capital formation, production volume, and labor productivity increased in the environment-friendly agricultural sector. In contrast, employment in the environment-friendly agricultural sector decreased. The price of environment-friendly agricultural products following the introduction of the DPS remain consistent with the price of environment-friendly agricultural product before introducing the DPS. This results from price elasticity of supply and demand are inelastic, and there is no change in the income of consumers during the analysis period. However, additional research is necessary for improvement of the model using complementary statistical data for the environmental-friendly agriculture sector.

  • Purpose - Despite the structural irrationality of multi-level transportation and the oil price rise, the domestic freight transportation market continues to grow, mirroring the rise in e-commerce and resultant increase in courier services and freight volumes. Several studies on courier services have been conducted. However, few studies or statistics have been published regarding regular freight services although they have played a role in the freight service market. The present study identifies the characteristics of regular freight service users to seek competitiveness enhancement measures specific to regular freight services. Research design, data, and methodology - IPA is a comparative analysis of the relative importance of and satisfaction with each attribute simultaneously. This study used IPA because it facilitates the process of analyzing importance and performance, deriving implications and a visual understanding of results. To enhance the competitiveness of regular freight services, this study surveyed its current users regarding the importance of the regular freight service factors. A total of 200 copies of a questionnaire were circulated and 190 copies were returned. In addition to demographics, respondents answered questions about the importance of and satisfaction with services on a 5-point Likert scale. Excluding 3 inappropriate copies, 187 out of 190 copies were analyzed. PASW Statistics 18 was used for statistical analysis. A total of 20 question items were selected for the service factors presented in the questionnaire based on the 1st pilot survey and previous studies. Results - According to the IPA performed to compare the importance of and satisfaction with service factors, both importance and satisfaction are high in the 1st quadrant, which involves the economic advantage of using regular freight services, quick arrival at destinations, weight freight handling, and less time constraints on freight receipt/dispatch. This area requires continuous management. Satisfaction is higher than importance in the 2nd quadrant, which involves the adequacy of freight, cost savings over ordinary courier services, notification on freight arrival, and freight tracking information. This area requires intensive investment and management. Satisfaction is lower than importance in the 3rd quadrant, involving the credit card payment system, courier delivery service, distance to freight handling sites, easy access to freight handling sites, and prompt problem solving. This area requires further intensive management. Both importance and satisfaction are low in the 4th quadrant, involving the availability of collection service, storage space at freight handling sites, kindness of collection/delivery staff, kindness of outlet staff, and easy delivery checks. This area is a set of variables should be excluded from priority control targets. Conclusions - Based on the IPA, service factors that need priority controls because of high importance and low satisfaction include the credit card payment system, delivery service, distance to freight handling sites, easy access to freight handling sites, and prompt problem solving. The findings need to be applied to future marketing strategies for regular freight services and for developing competitiveness enhancement programs.

  • The aim of this study was to establish research hypotheses and conduct empirical analysis to clarify the relationship between self-leadership, self-efficacy, job satisfaction, and job performance of researchers in the energy and environment fields. Data were extracted from questionnaires returned by 165 researchers in the field of energy environment among 200 questionnaires collected for approximately three weeks. The reliability, frequency, descriptive statistics, correlation analysis, multiple regression analysis, and sobel-test were examined using the SPSS 22.0 statistical program. The self-leadership of the researcher has a positive (+) effect on self-efficacy, job satisfaction, and job performance, and the researcher's self-efficacy has a positive (+) influence on both job satisfaction and job performance. In addition, the self-efficacy and job satisfaction mediated the relationship between self-leadership, and job performance. Therefore, to improve the job performance of the researchers, it is important to establish a system for the human resource management of the affiliated institutions and revitalize the education for the self-leadership and self-efficacy improvement. In addition, it is necessary to provide an appropriate compensation system to satisfy the researchers' enjoyment, satisfaction and trust in their jobs. In particular, because self-efficacy is a very important factor for job performance, it is important to prepare an institutional strategy for strengthening the self-efficacy of researchers.

  • As the research for analyzing the awareness and the performance level for infection control of radiological technologists working at the clinic located in Gyoungsangnam province, this study was conducted to provide the basic education data of infection control for radiological technologist who works in the clinic. During July 14, 2014 to March 31, 2015, after we sent out a total of 150 questionnaires for the survey to radiological technologists working at the clinic located in Gyoungsangnam province, 131 questionnaires suitable for research were analysis by using SPSS 18.0 statistical analysis software. As the infection control factors, a total of 60 items about the awareness and the performance level for infection control (12 items for infection control characteristics included) were analyzed. Descriptive statistics, t-test, ANOVA, correlation, and regression analysis were performed based on the general characteristics of the study subjects. Regarding the awareness factor for infection control, the total awareness level was high as $4.15{\pm}.05$ and the total performance level was also high as $4.05{\pm}.05$. Through these results, although the performance level was slightly lower than awareness level, the level of infection control of the radiological technologists working at the clinics located in Gyeongnam was analyzed to be relatively high. The infection control of the clinic's radiological technologist should be carried out through the continuous infection education and prevention activities of the hospital staff, and radiological technologist working in clinics should also be positioned as specialists in infection control.

  • The purpose of this study is to present theoretical and policy implications based on the results of the empirical analysis of job stress in consideration of insufficient prior research on the level of job stress by public officials in charge of social welfare and public officials in general administration. For this purpose, social welfare and general administrative positions working at the City Hall of G Metropolitan City and five autonomous districts(including the Dong community service center) were selected as subjects for research. The data analysis used the SPSS statistical program to obtain technical statistics based on the average of the lower variables of the job stress. According to the analysis, there is a difference in the subjective perception level of public officials in charge of social welfare and public officials in general administration in both internal factors of job, such as job demands and job autonomy and external factors of job, such as job insecurity, organizational system, conflict of relations, inadequate compensation, and job culture. Based on this, it presented policy measures that require the granting of self-esteem of public officials in charge of social welfare, improvement of their duties, and adjustment of their workload to an appropriate level.
