The purpose of this study was to identify the multidimensional factors that affect the satisfaction of life by type of baby boomer generation. The subjects of this study were 1,895 households who were born from 1955 to 1963 among the respondents in the Korea welfare panel (the 10th year). The baby boomer generation was classified into four types such as gender, income status, male and female as socioeconomic status. The male type IV (B=.074, t=1.992, p<.05), health status (B=.233, t=7.268, p<.001), household income (B=.174, t=4.476, p<.001), depression (B=-.182, t=-5.242, p<.001), self-esteem (B=.255, t=7.027, p<.001), trust (B=.064, t=2.036, p<.05), etc. were found to have a significant effect on the life satisfaction of the male baby boomer generation. The female type IV (B=.100, t=2.598, p<.05), health status (B=.239, t=6.790, p<.001) (P<.001), depression (B=-.181, t=-5.142, p<.001), and self-esteem (B=.320, t=8.600, p<.001), etc. were found to have a significant effect on the life satisfaction of the female baby boomer generation.

Economic conditions of Korean agriculture have been aggravated since farmers experienced the shortage of labor, instability of farm product price, lack of capital and pressure of opening domestic market. Nevertheless, agriculture must be maintained because structure of national economy can not be progressed without balanced growth of food industry. So the problem that we must solve is to keep agriculture competitive. In that case technology is important in terms of improving productivity, overcoming labor shortage and stabilizing price. This paper is to study the technology adoption on the farm level, focusing on the theories of technology adoption, their empirical test and effect of technology adoption on the farm household income. In this study five theories-independent model, linear model, middle class conservation model, modified middle class conservation model, basic needs and wealfare model- were introduced concerning differentiated technology adoption rate by farmers' class. Based on the survey of controlled strawberry farming in Nonsan County, Chungnam Province, who adopted six kinds of technology, modified middle class conservation model was found to explain five kinds of technology adoption pattern and linear model was useful to explain one kind of technology, that is, irrigation method, These results may mean that controlled strawbary cultivators of middle class were reluctant to accept new technology. There are many variables to effect on the technology accepting rate, that is, farmer's age, labor capacity, education level, cultivation career, size of total cultivated land, and size of strawberry farming land. LOGIT model was used to find which variable influence the technology adoption rate. Results of estimation showed that variables of cultivation career and total land size, of which coefficients were statistically significant at the 5 percent level, might be main influential factors in accepting more than three farming techniques. There was a significant income difference between farm households accepting new methods and those rejecting them. Especially in case of low class of farming group, income of farmers who was adopting new technology was examined to be much higher than that of farmers who did not adopt. This result suggests that new technology play an important role in increasing farm household income. Finally this study emphasized that there is a need to develop proper measure of technology transfer considering various socioeconomic conditions of farm households.

Recently, the number of the elderly has increased according to the improvement of socioeconomic status and the efficient medical care system. In spite of the development of medicine, the elderly suffers from the various health problems caused by weakness of musculoskeletal system, cardiopulmonary function and immunologic dysfunction. Regular rhythmic exercise program is known to be one of the effective tools to enhance the health condition in the elderly. However, there has been few studies to evaluate the comprehensive effects of rhythmic movement program on the elderly. This study was focused to evaluate the indices of cardiopulmonary function, life satisfaction, calcium, phosphorous, osteocalcin and deoxypyridinoline which are the essential factors of health problems in the elderly women. Twenty six subjects, aged between 68 and 72, who can do the ordinary activities and do not have cardiovascular dysfunction and mental disorder, participated in this study. They were divided into two groups: 13 in the experimental group and 13 in the control group. The experimental group participated in the rhythmic movement program at the welfare center located in G-city. The program were consisted of three sessions a week during 10 weeks. Each session had three parts: warming up(10 minutes), main exercise(40 minutes), finishing(10 minutes). Heart rate, blood pressure and peripheral arterial oxygen saturation were measured for the evaluation of cardiopulmonary function. Serum calcium, phosphorous, osteocalcin and urine deoxypyridinoline were measured as the indices of bony metabolism. Data were analyzed with mean, standard deviation, $x^2$-test, t-test, paired t-test using SPSS PC+ program. The results of this study were as follows. 1) Heart rate of the experimental group showed significant decrease following the rhythmic movement program. Peripheral arterial oxygen saturation of the experimental group showed significant increase following the program. 2) The degree of life satisfaction of the experimental group showed significant increase following the program. 3) Calcium showed significant decrease following the program but remained within normal range. There was no significant difference of phosphorous between two groups. 4) Osteocalcin, the index of bone formation, showed no significant change following the program, but significant increase in the experimental group comparing with the control group. 5) Deoxypyridinoline, the index of bone resorption, in urine of the experimental group showed significant decrease following the program. In conclusion, the rhythmic exercise program in the elderly showed the improvement of physiologic function and favorable effects on life satisfaction and bony metabolism. According to the above results, the regular rhythmic movement program can be strongly recommended for the improvement of health in the elderly women.

Current socioeconomic condition in South Korea is characterized by growing country with highly unemployment rate. Enhancing service industry, therefore, is one of the important government policy issues. In addition to quantitative growth of service industries, OECD comparisons between countries as shown in the competitiveness of the domestic service industry, followed by a very low-level, enhancing the competitiveness of service industries are also important issues of national policy. In particular, finance, education, insurance industry, such as relatively large enterprises have entered the service industry to remain competitive and comparable, but the case of small service industries, has shown a very low level of competitiveness. Thus, the world's leading technology and IT infrastructure can be applied to small and medium-sized service industry in order to improve productivity, customer satisfaction, and service infrastructure, resulting in improving competitiveness. The purpose of this study is to develop government supporting policy issues by analyzing the current usage of IT, problems and requirement analysis, and critical success factors for applying IT to small and medium-sized service industries. For a survey 2,000 samples are collected from service companies. The results show that IT usage is very important to improve competitiveness in small and medium sized service industry. In addition, customized it solutions are needed to satisfy different characteristics of service industry depends on types of business. Finally, government supporting programs of IT has to be improved. The results would be able to provide directions and guide lines of IT utilization in service industries.

Objectives: The purpose of this study was to examine the relationship between the differences in employment status and self assessed health in Korea. Methods: We analyzed 4 year follow-up data generated by the Korean Labor and Income Panel Study(KLIPS), which was conducted on 1,207 men and 582 women who had undergone a change in employment status. The study subjects were placed into 1 of the following 4 groups based on their employment history; Non-precarious workers, Precarious to non-precarious workers, Non-precarious to precarious workers and Precarious workers. Logistic regression was then used to examine the relationship between the changes in employment status and self assessed health. Results: When males were considered, self assessed health was better among the precarious to non-precarious workers (OR 1.58, 95% CI=1.57-1.60) and the precarious workers (OR 1.29, 95% CI=1.28-1.30) than in the non-precarious workers, after adjusting for age, socioeconomic status (education level, occupational class, marital status, average equivalent household income and average number of hours worked per week), health behavior (smoking, drinking and exercise) and medical service access (regular medical examination, have chronic disease or hospitalized within 1 year). When female workers were considered, the precarious to non-precarious workers (OR 1.89, 95% CI=1.86-1.92), non-precarious to precarious workers(OR 1.24, 95% CI=1.23-1.26) and precarious workers (OR 1.27, 95% CI=1.25-1.28) all reported poorer health than the non-precarious workers after adjusting for the aforementioned factors. Conclusions: This study showed that changes in employment status were associated with differences in self assessed health among men and women. Specifically, the results of this study showed that a corresponding positive outcome based on self assessed health was greater for employees that changed from precarious to non-precarious jobs and for male employees with precarious jobs., whereas female employees with non-precarious jobs had higher self assessed health. However, additional longitudinal studies on the health effects of employment status should be conducted.

Measurements of health related quality of life can be used to compare patients with specific conditions to average individuals in the general population in a similar age and gender group. However there are few data available regarding health related quality of life for the general population of Korea. Therefore, this study was conducted to examine the validity of the Korean version of EQ-5D and to measure the health related quality of life of the general adult population in a metropolitan city. The survey was cross-sectional and employed a stratified and multistage sampling design through 100 examination sites in 5 districts of UIsan. A total of 12,644 individuals from 4,112 households participated in the survey. Of these, we analyzed data from 8,068 adults who were over 19 years old and completed the EQ-5D. To examine the validity of the questionnaire, the differences in 5 dimensions and the $EQ-5D_{index}$ were analyzed with regard to demographic and socioeconomic factors such as sex, age, income, and education. In addition, visual analogue scales (VAS) were used to evaluate the overall health related quality of life issues of the respondents. The level of health related quality of life of the general adult population was then compared with the results from the third Korean National Health and Nutrition Examination Survey and other countries. There were a small number of people with problems related tomobility, self-care, and usual activity. In addition, many people complained ofpain/discomfort and anxiety/depression. The complaint rate in each dimension, VAS, and $EQ-5D_{index}$ indicated relatively better states for males, the younger group, the higher income group, and the higher education group. In addition, the level of health related quality of life of the general population of Ulsan was relatively higher than that of Koreans nationwide as well as the populations of other countries. EQ-SD provided a valid measure of the health-related quality of life of the general adult population. In addition, the results of a survey of Ulsan revealed that the quality of life of its population is better than that of the overall population of Korea and of the populations of other countries.

Fungal pathogens have huge impact on health and economic wellbeing of human by causing life-threatening mycoses in immune-compromised patients or by destroying crop plants. A key determinant of fungal pathogenesis is their ability to undergo developmental change in response to host or environmental factors. Genetic pathways that regulate such morphological transitions and adaptation are therefore extensively studied during the last few decades. Given that epigenetic as well as genetic components play pivotal roles in development of plants and mammals, contribution of microbial epigenetic counterparts to this morphogenetic process is intriguing yet nearly unappreciated question to date. To bridge this gap in our knowledge, we set out to investigate histone modifications among epigenetic mechanisms that possibly regulate fungal adaptation and processes involved in pathogenesis of a model plant pathogenic fungus, Magnaporthe oryzae. M. oryzae is a causal agent of rice blast disease, which destroys 10 to 30% of the rice crop annually. Since the rice is the staple food for more than half of human population, the disease is a major threat to global food security. In addition to the socioeconomic impact of the disease it causes, the fungus is genetically tractable and can undergo well-defined morphological transitions including asexual spore production and appressorium (a specialized infection structure) formation in vitro, making it a model to study fungal development and pathogenicity. For functional and comparative analysis of histone modifications, a web-based database (dbHiMo) was constructed to archive and analyze histone modifying enzymes from eukaryotic species whose genome sequences are available. Histone modifying enzymes were identified applying a search pipeline built upon profile hidden Markov model (HMM) to proteomes. The database incorporates 22,169 histone-modifying enzymes identified from 342 species including 214 fungal, 33 plants, and 77 metazoan species. The dbHiMo provides users with web-based personalized data browsing and analysis tools, supporting comparative and evolutionary genomics. Based on the database entries, functional analysis of genes encoding histone acetyltransferases and histone demethylases is under way. Here I provide examples of such analyses that show how histone acetylation and methylation is implicated in regulating important aspects of fungal pathogenesis. Current analysis of histone modifying enzymes will be followed by ChIP-Seq and RNA-seq experiments to pinpoint the genes that are controlled by particular histone modifications. We anticipate that our work will provide not only the significant advances in our understanding of epigenetic mechanisms operating in microbial eukaryotes but also basis to expand our perspective on regulation of development in fungal pathogens.
