Since the 1960s, Korea has achieved rapid economic growth, longer life expectancy, accelerated urbanization and a westenization of diet. Cardiovascular disease has become the leading cause of death; however the prevalence of ischemic heart disease(IHD) remains low. A cross-sectional multiphasic screening service for 18,426 persons aged $30\sim64$ years in a Medical Aid Program in Kyonggi-do Province was conducted from 1991 to 1993. Total cholesterol(TC), fasting blood glucose(FBG), blood pressure(BP), and electrocardiographic(EKG) data were collected. The result as follows ; 1. On the EKG findings, the age-adjusted prevalence of myocardial ischemia and myocardial infarction was 1.45% in men and 2.06% in women. 2. The mean blood pressure was 122.9/78.8mmHg. The age-adjusted prevalence of hypertension was 11.05% in men and 9.02% in women. The prevalence of hypertension showed increasing tendency according to age increase. In all age group, the prevalence of hypertension was higher in men than women. 3. The mean total cholesterol level was 184.4mg/dl in men and 189.2mg/dl in women. The age-adjusted prevalence of hypercholesterolemia was 4.88% in men and 5.67% in women. The total cholesterol level showed increasing tendency according to age increase, except $55\sim64$ age group in men. 4. The prevalence of hyperglycemia is 5.8%. The age-adjusted prevalence of hyperglycemia is 6.72% in men and 4.50% in women. The prevalence of hyperglycemia showed increasing tendency according to age increase. 5. On the EKG findings, the prevalence of myocardial ischemia and myocardial infarction was higher in hypertension than normal, in all age group of men and women less than 40 years-old. Only in women more t]fan 40 years-old, the prevalence of myocardial ischemia and myocardial infarction was higher in hypercholesterolemia and hyperglycemia. Nevertheless there is not statistical association between ischemia heart disease and previous risk factors in other age group, the prevalence of myocardial ischemia and myocardial infarction was higher in hypertension, hypercholesterolemia and hyperglycemia than normal. The result of this study suggest that relationships between major risk factor of ischemic heart disease and ischemic heart disease is similar to existing theory.

This study collected 5,100 cases of gas accident occurred in Korea for 14 years from 1995 to 2008, established Database and based on it, analyzed them by detailed forms and reasons. As the result of analyzing the whole city gas accidents with Poisson analysis, the item of "Careless work-Explosion-Pipeline' showed the highest rate of accidents for the next 5 years. And, "Joint Losening and corrosion-Release-Pipeline" showed the lowest rate of accident. In addition, for the result of analyzing only accidents related to LPG vaporizer, "LPG-Vaporizer-Fire" showed the highest rate of accident and "LPG-Vaporizer-Products Faults" showed the lowest rate of accident. Also, as the result of comparing and analyzing foreign LPG accident accompanied by Jet fire, facility's defect which is liquid outflow cut-off device and heat exchanger's defect were analyzed as the main reason causing jet fire, like the case of Korea, but the number of accidents for the next 5 years was the highest in "LPG-Mechanical-Jet fire" and "LPG-Mechanical-Vapor Cloud" showed the highest rate of accidents. By grafting Poisson distribution theory onto gas accident expecting program of the future, it's expected to suggest consistent standard and be used as the scale which can be used in actual field.

Inter-Korean Cooperation in Science and Technology will contribute to building the trust between S.K and N.K as a leading factor and cut down the cost of unification by diminishing the technology lag and the gap of economic level. This study has shown that we can increase the productivity of unified Korea Innovation system if we systematically analyse the present condition of the Inter-Korean Cooperation and promote Inter-Korean Cooperation. In this study, the author analyses the present condition of the Inter-Korean Cooperation with integrated framework of three aspects to clear up the policy of Inter-Korean Cooperation. First, in the national aspect, we make use of the notion of international cooperation and multilateral mechanism of an international organization. Thereafter, we make out the alternatives in the aspects of international relationship and legal and institutional view Second, in the unification aspect, we consider the Inter-Korean Cooperation by the notion of national innovation system. Thereafter, we make out the alternative in the aspect of a phase-dependent approach. Finally, in technology aspect, we consider the Inter-Korean Cooperation by the notion of technology gap, the framework of technology transfer, and technology dependency theory. As a conclusion, through this study, the author have tried to integrate the various theoretical backgrounds. As a result, the author could analyse the present condition of ter-Korean Cooperation in Science and Technology and team a good lesson from it; Therefore, we can use it as a means of evaluation on a cooperation program and prediction for the future status of cooperation.

This study purported to examine the effects of precarious employment and social capital on the changes of self-rated health status among the middle aged and the young-old population in South Korea. The study analyzed 12 year follow-up data generated by the Korean Labor and Income Panel Study(KLIPS 6-17), which included 10532 employed subjects aged 55 to 75. Multi-level growth curve modeling was performed by fixed and random effect models using STATA 13.0 program. Afterwards, Hausman test was performed, which resulted in support of the estimation by fixed effect model. The results showed that a day labor position was significant factor affecting the deteriorated changes of self-rated health status over time. In addition, wage, weekly working hours, and private/relational social capitals were also found to be significant factors affecting the changes of the self-rated health status. The results supported the divergence hypothesis as well as the cumulative advantage theory. Efforts should be made to develop and implement various employment support policies and social service programs to alleviate the health inequality of the employed workers over their middle-aged to young-old period.

This paper aims to apply our research and theorization on arts entrepreneurship to entrepreneurs active in the arts and cultural sector. Our goal is to develop proposals for practical actions that can support both arts entrepreneurs and supportive arts advocates. Using Action Research methodology, we hosted and facilitated two workshops with selected groups of arts entrepreneurs. Prior to the workshops we designed a questionnaire, based on the competency theory, to assess the qualities and characteristics of the participants. During the workshops we conducted surveys, interviews, and made observations in order to further understand the knowledge, experiences, motivations, capabilities, and attitudes necessary to successful arts entrepreneurship. We also conducted in-depth follow-up interviews with participants as a cross-check. We found that most of the participating arts entrepreneurs had a low understanding of the technology required for effective arts entrepreneurship, which has resulted in insufficient managerial support for artistic innovation. In addition, we found that participants lacked the skills and clear vision to construct a viable economic engine for their organization. Nevertheless, in light of the considerable strengths and high levels of enthusiasm and commitment participants evinced, we believe that their deficits can be corrected with education and training. Thus, we conclude by discussing the path forward and outlining a proposal to develop an innovative educational program on the daily operations of arts management that emphasizes applied technology and creating financial sustainability.

Purpose: This research is based on experiments practiced with 6th grade students in primary school as subjects. They were trained in basic cardiopulmonary resuscitation theory and received actual training in CPR. Methods: The subjects were randomly sorted into two classes of the 6th grade students. The experimental group was composed of 35 students. The control group was composed of 32. The experimental group received basic CPR theoretical and practical education once and received a practical evaluation three times, with 4 weeks in between evaluations. The control group received CPR theoretical education before the study. The data was analyzed by ${\chi}^2$-test and t-test using the SPSS/WIN 12.0 program. Results: Hypothesis 1 was that the basic CPR knowledge score would begin to decrease right after the education and continue to decrease as time passed. The experimental group's knowledge score continued to increase 12 weeks after education, but there was no decrease in the control group's knowledge score (F=5.870, p=.000). Hypothesis 2 was that the basic CPR attitude score would decrease right after the education and continue as time passed. There was no significant difference in the experimental group's score after education, nor was there any change in the control group's score on this measure (F=3.986, p=.004). Hypothesis 3 was that the subjects' confidence in practicing CPR would decrease right after education and continue as time passed. There was a significant decrease in the experimental group's score, but no significant change in the control group's score on this measure (F=75.574, p=.000). Hypothesis 4 was that the practical accomplishment evaluation score of CPR would decrease as time passed. There was a significant decrease in the experimental group's score on this measure right after education (F=38.368, p=000). Conclusion: Retraining for basic CPR education will be needed in all aspects of the education/training at least every 4 weeks, to preserve the students' retention of learned material/training. This is because students' scores fell significantly four weeks after education/training.

The purpose of this study was to identify the effect of new graduate nurses' empathy and their perceived preceptors' empathy on job satisfaction, job stress and turnover intention. For this purpose, a survey was conducted on new graduate nurses who were under 12 months old while working at three medical institutions that operated the preceptorship. In the preceptorship according to adult learning theory, the preceptors need to create a psychological environment for the new graduate nurses, and their empathy should be perceived by new graduate nurses. The study revealed that the new graduate nurses group with high level of empathy had high levels of job satisfaction, low job stress, and low degree of turnover intention, and the level of empathy affects job satisfaction of new graduate nurses. The new graduate nurses group with low level of perceived preceptor's empathy had low job satisfaction, high job stress, and high degree of turnover intention, and their perceived preceptor's empathy affected job stress and turnover intention. Based on these results, we suggest the introduction of a program to enhance empathy for new graduate nurses and preceptors.

The purpose of this study is to identify acceptance factors and influencing factors of respondents' adoption of smart IoT technology to companion animal health based on the integrated technology acceptance model. Based on the previous studies, we constructed the hypotheses by defining the technical factors, social factors, control variables, and mediating variables (UTAUT), and set the hypotheses between the independent variables of each factor and the dependent intention. A research model was designed to verify the relationship between variables. We developed questionnaires on the items and verified them through data collected from 494 people. As a result, product design, quality of service, product performance, and quality service of technological factors had a significant effects on performance expectancy and effort expectancy. However, product safety, product function awareness, and product price did not significantly affect performance expectancy and effort expectancy. Social influence had significant effects on cognitive effect, welfare system, and welfare facilities. In conclusion, the comparative analysis of technical factors and social factors showed that social factors have more significant effects on welfare systems and facilities.

The purpose of this study is to examine the mediating effect of depression on the relationship between assets and life satisfaction in Korean elderly (45 years old or older). To this end, we used the data from the KReIS 5th Main Survey (2013). SPSS 21.0 and AMOS 25.0 were used for data analysis. The analysis methods were descriptive statistical analysis, correlation analysis, regression analysis and path analysis. As a result of the analysis, first, the assets of middle-aged and old age had a negative effect on depression, and the depression had a negative effect on life satisfaction. Second, the assets of the elderly have a positive effect on the satisfaction of life. Third, the effects of assets on the satisfaction of life were found to be mediated by depression of middle-aged people. Based on the analysis results, this study suggested the introduction of middle age generation's asset formation support program, the universal implementation of basic pension for the elderly generation, and the gradual increase in benefits.
