  • The empirical study that used the logit model and the Heckman's selection bias model based upon 'Korea Labor & Income Panel Study' shows that the experience of job training has a positive effect on the probability of employment, as well as on the wage increase. The analysis also sheds light on the effect on employment with wage workers who experienced job training. When the discouraged unemployed are not classified as labor force participants, that is the unemployed, and the industrial dummy variables are excluded, logit estimation shows that training program in the public sector, not in the private sector, significantly increases their employment probability. However when these same workers are classified as the unemployed and the industrial dummies are included, logit estimation shows that public and private training programs has no effect on their employability.

  • Purpose: The purpose of this study was to examine the relationships between self-efficacy and health promotion lifestyle in middle and high school teachers. Methods: This study used survey data from 26 middle and high schools The study included 181 teachers who completed questionnaires. The questionnaires were consisted of demographic and occupational characteristics, self-efficacy on health behaviors, and Health Promotion Lifestyle Profile (HPLP). Analyses were done using frequency, percentage, correlation, and multiple regression analysis with dummy variables. SAS 8.2 was used. Results: Mean self-efficacy score on health behaviors was 4.1${\pm}$0.5. Mean health promotion lifestyle scores were healthy diet (2.4${\pm}$0.5), physical activity (2.0${\pm}$0.8), stress management (2.3${\pm}$0.5), self-fulfillment (2.9${\pm}$0.5), responsibility of health (2.3${\pm}$0.6), and personal relationship (2.7${\pm}$0.6). Self-efficacy was significantly related to all health promotion lifestyle scores (healthy diet, physical activity, stress management, self-fulfillment, responsibility of health, and personal relationship). Among demographic and occupational characteristics, sex and school level was significantly related to healthy diet. Sex was significantly associated with physical activity. Marital status was significantly related to responsibility of health. Conclusions: The results showed that intervention programs for middle and high school teachers targeting health promotion lifestyle are needed. These intervention programs would be effective when sex, age, marital status, and school level are considered. In addition, given that higher self-efficacy was related to higher health promotion lifestyle scores, it strengthens the need for further investigations aimed at how to change self-efficacy in teachers.

  • Purpose : Various research studies are needed to raise the perception of the CE of Korean physical therapists. However, there are little studies have been conducted, and relatively few studies are available to read on online. The purpose of the study is to find out the differences in the perception of CE according to the physical therapist's academic background. In this way, this article intends to strengthen the perception of the CE of health-care workers, such as physical therapists and occupational therapists in the Republic of Korea so that contributing to the development of national health. Methods : Present study showed that 431 out of 563 people who participated in the two meetings of CE conducted by the Gwangju Metropolitan City of the Korea Physical Therapy Association responded in the survey in 2015. Among them, only 238 people were surveyed on the awareness of CE in 2014, excluding 181 questionnaires due to poor responses and 112 questionnaires that did not participate in CE in the previous year. Descriptive analyses were conducted to identify the perception among those who experienced CE, and simple linear regression analysis was performed using dummy variables to identify awareness of the education based on their academic background. Results : Question 3 (p=.000, R2=.067) was significant in the significance test of the regression equation for perception of the CE (p<.05). Question 1 (p=.687), 2 (p=.066), 4 (p=.430), 5 (p=.085), and 6 (p=.054), 7 (p=.111), 8 (p=.088), 9 (p=.213), 10 (p=.191) and 11 (p=. 169), the regression formula was not significant (p>.05). Conclusion : Physical therapists had a moderate perception of the need for a CE and had the idea that improvements were required in what was provided in that education. In addition, there was no statistically significant difference, although there was a greater awareness of CE in the Master of Science Course or higher than college or university graduates.

  • Purpose: The purpose of this study was to investigate the effects of job stress and support from supervisors on depression of care givers in elderly care facilities. Methods: Subjects were 191 care givers working in elderly care facilities in K-Province in Korea. Data were collected from self-administered questionnaires. Descriptive statistics, ${\chi}^2$ test, t-test, F-test, Pearson's and Spearman's correlation coefficients, and hierarchical multiple logistic regression with dummy variables were used for statistical analysis of data. Results: Job stress measured with Korean Occupational Stress Scale was $56.16{\pm}5.88$. Emotional and instrumental support from supervisors were $37.05{\pm}7.30$ and $32.39{\pm}7.34$, respectively. After controlling for general characteristics, job stress was significantly related to depression (OR: 1.07, 95% CI: 1.01~1.14). However, job stress became non-significant in the model that included instrumental support from supervisors. Not emotional but instrumental support from supervisors was significantly related to depression of care givers (OR: 0.93, 95% CI: 0.88~0.99). Conclusion: Results of this study suggest that job stress has negative effects and instrumental support from supervisors has protective effects on depression of care givers in elderly care facilities. Therefore, measures to increase instrumental support by supervisors should be developed to improve psychological health of care givers in elderly care facilities.

  • Purpose: The purpose of this study was to compare differences in spiritual needs (SNs) and factors influencing SNs between patients with progressive terminal kidney disease and their family caregivers. Methods: An explorative comparative survey was used to identify the SNs of patients (N=102) with progressive terminal kidney disease undergoing hemodialysis and their family caregivers (N=88) at a general hospital located in Seoul, South Korea. The data were analyzed using descriptive statistics, the chi-square test, the independent t-test, one way analysis of variance, the Scheffe test, and multiple regression with dummy variables. Results: The SNs among family caregivers were higher than in the patient group. SNs were higher among those who were religious in both groups. Loving others was the highest-ranked subdimension in the patient group, followed in descending order by maintaining positive perspective, finding meaning, Reevaluating beliefs and life, asking "why?", receiving love and spiritual support, preparing for death, and relating to God. In the family group, the corresponding order was maintaining positive perspective, loving others, finding meaning, receiving love and spiritual support, preparing for death, relating to God, and asking "why?". The factors that had a negative influence on the level of SNs were not being religious in the patient group and having only a middle school level of education in the family group. Conclusion: The results of this study may serve as evidence that spiritual care for non-cancer patients' family caregivers should be considered as an important part of hospice and palliative care.

  • The paper uses a panel gravity model to analyse the determinants of export via Gwangyang port for the period from 2000-2012. The gravity model includes export via Gwangyang port, GDP and population of trading partners, the distances between Korea and its partners, and Korea-ASEAN FTA dummy. Hausman test shows up which one is exactly appropriate between random effect estimation and fixed effect estimation to use panel dataset. It depends on whether or not existence or nonexistence of the correlation between unobserved omitted factors and variables. Fixed effect estimation is suitable for this paper by the rejection of null hypothesis. An Empirical analysis of this paper shows GDP influences positive effects and distance influences negative effects to Gwangyang port trading partners. In addition, the results strongly supported the effects of Korea-ASEAN FTA on the growth of Gwangyang port export.

  • We try to find the determinants of fisheries firms' capital structure during the years from 1992 to 2007 in this paper. We also have a comparative analysis of capital raising behavior in pre and post-IMF financial crisis. Regression analysis is used for this empirical study. Dependent variable is leverage ratio and independent variables are firm size, operating risk, proportion of tangible asset, non-debt tax shield effect, sales growth ratio, profitability and dummy variable. We compared the characteristics of fisheries industry with that of manufacturing industy. The determinants of fisheries firms' capital structure and correlation between pre and post-IMF financial crisis are roughly same as the hypothses except a little difference. As a peculiar difference, corrlation between fisheries firms' operating risk and leverage ratio is (+) in the pre-IMF financial crisis, but (-) in the post-IMF financial crisis. Proportion of tangible asset has a (+) correlation with leverage ratio in pre and post-IMF financial crisis, but in case of manufacturing industy, (-) correlation shows in the pre-IMF financial crisis. Because, in the pre-IMF financial crisis, high proportion of tangible asset doesn't play a role of a collateral, but only increase the bankruptcy probability. Non-debt tax shield effect and leverage ratio have (-) correlation in all industry and all period, but only (+) correlation in case of fisheries industry in the pre-IMF financial crisis. Sales growth ratio has no significant relationship with leverage ratio in fisheries industry, and this is not coincide with our hypothsis. We have a limitation of the sample size of fisheries firms and sample period in this study. Further study is required to classify the fisheries industry with in-shore fisheries, deep sea fisheries and cold storage industry.

  • As the gravity of the issue of the global warming surfaced, environmental protection and energy conservation have become one of the most serious issues that global society faces. At the status quo, there are criticisms for not effectively educating the students although the problem is very severe. In middle school, for instance, only 10% of the school offer environmental education while only $20{\sim}30%$ of the high school offer it. As witnessed by these examples, we can infer that there are not well-structured, effective environmental education for teenagers. Recently, NIE(Newspaper-In-Education) has been used as effective means for some fields of middle and/ or high school education. If so, it also could be used for environmental education. The researches, however, on the topic of NIE on environmental education are very rare. In this study, the effect of NIE on environmental education was empirically tested. Our basic assumption is that NIE will cause differences in environmental perception; the cognition and concern. And environment education through NIE will cause the high level of cognition, concern, and practice regarding environment issue. Using simple experimental design and regression analysis, we tested the effect of NIE on cognition, and, concern of environment issue, and then, on the practice of environment-improving action. The "cognition level" did not show significant difference between the experimental group(which was exposed to NIE) and control group(which was not exposed to NIE). The "concern level" for environment showed significant difference. Finally, the "practice level" showed highly significant difference between the experimental and the control group. According to regression analysis, "concern" and "NIE"(dummy variable) was turned out to be statistically significant variables for practice of environment improving action. Therefore, we came up with the conclusion that NIE, which provides the most up-to-date information regarding the environmental status, can serve as the good supplementary mechanism for the effective environment education in the present Korean middle school curriculum system. The statistical result also suggests that each individual school needs to employ and extend NIE method in its environment education curriculum.

  • The objective of this paper is to analyze expenditure structures and impact factors of household's transportation cost in order to provide policy-maker with quantitative and economic information for reducing household's transportation costs, using 1995-2007 household survey data. For this purpose, this study performed various economic analysis, including econometric regression analysis and income re-distributional effects. The four models were separately estimated with dependent variable (personal and public costs, public transit and private car costs) and independent variables (family, employ, age, education, cars, household income, region dummy variable). In addition, We analyzes impacts of transport policy instruments on the transportation expenditure. These instruments include changes of oil price and public transit fare, reform of public transport system, and extension of subway facilities. Finally, income re-distributional effects before and after transportation expenditure, using Pechman-Okner (PO) index and Wolfson index.

  • There is not enough absorption space in the side of a vehicle so injuries to a passenger are higher compared to frontal impact injuries. For the protection of the passenger in the event of a side impact, vehicle regulations and new car assessment program(NCAP) are implemented all over the world. However, passive safety such as absorption technology of vehicle body itself is limited due to the narrow space of the side part. At the present time, it is well known that a side airbag including a curtain airbag is the most effective system to protect the passenger during a side impact. In this study, optimum design of the curtain airbag is carried out to reduce Head Injury Criterion(HIC) of the passenger. Based on crashworthiness simulation, an orthogonal array is selected based on the defined design variables, the response surfaces are generated from the orthogonal array and optimization is conducted with the surfaces.
