In recent time, rural-studying programs have emerged as an alternative to promoting exchange between urban and rural areas. The purpose of this research will be to take a look at such exchange activities through the study of cases involving rural areas using its human and material resources. The research will also consider the implications resulting from the possibility of its application in Korea. According to a Japan's rural-studying program, there was a whole family participation and there was cooperation between the school, village and the local government. There are some domestic places that applied this program, but only a few are successfully being implemented. To increase the possibility of successful application, building network systems between rural-studying schools will be vital. So will be the building of critical infrastructure to induce the return to farming and the establishment of assistance institutions. Also, visible assistance towards farms in rural area and conversion of recognition upon exchange activities between urban and rural will be necessary. Legislation of rural-studying program, establishment of local government assistance ordinance and continual education to local inhabitants will be central to the role of central and local government.

Members of the Vps (Vacuolar protein sorting) protein family involved in the formation of the retromer complex have been discovered in a variety of species such as yeast, mouse, and human. A mammalian retromer complex is composed of Vps26, Vps29, and Vps35 proteins and plays and important role in cation-independent mannose-6-phosphate receptor retrieval from the endosome to the trans-Golgi network. In this study, we have identified the full-length sequences of the retromer components of Vps26, Vps29, and Vps35 in micro pigs. The cDNA sequences of these retromer components have been determined and the result showed there is 99% homology among the component counterparts from mouse, micro pigs, and humans. In addition, the retromer complexes formed with hetero-components were found in the brain of micro pigs. Based on above results, we suggest mammalian Vps components are well conserved in micro pigs.

The impact of overproduction of a heterologous protein on the metabolic system of host Lactococcus lactis was investigated. The protein expression profiles of L. lactis IL1403 containing two near-identical plasmids that expressed high- and low-level of the green fluorescent protein (GFP) were examined via shotgun proteomics. Analysis of the two strains via high-throughput LC-MS/MS proteomics identified the expression of 294 proteins. The relative amount of each protein in the proteome of both strains was determined by label-free quantification using the spectral counting method. Although expression level of most proteins were similar, several significant alterations in metabolic network were identified in the high GFP-producing strain. These changes include alterations in the pyruvate fermentation pathway, oxidative pentose phosphate pathway, and de novo synthesis pathway for pyrimidine RNA. Expression of enzymes for the synthesis of dTDP-rhamnose and N-acetylglucosamine from glucose was suppressed in the high GFP strain. In addition, enzymes involved in the amino acid synthesis or interconversion pathway were downregulated. The most noticeable changes in the high GFP-producing strain were a 3.4-fold increase in the expression of stress response and chaperone proteins and increase of caseinolytic peptidase family proteins. Characterization of these host expression changes witnessed during overexpression of GFP was might suggested the metabolic requirements and networks that may limit protein expression, and will aid in the future development of lactococcal hosts to produce more heterologous protein.

The female reproductive tract has two main functions: protection against microbial challenge and maintenance of pregnancy to term. The upper reproductive tract comprises the fallopian tubes and the uterus, including the endocervix, and the lower tract consists of the ectocervix and the vagina. Immune cells residing in the reproductive tract play contradictory roles: they maintain immunity against vaginal pathogens in the lower tract and establish immune tolerance for sperm and an embryo/fetus in the upper tract. The immune system is significantly influenced by sex steroid hormones, although leukocytes in the reproductive tract lack receptors for estrogen and progesterone. The leukocytes in the reproductive tract are distributed in either an aggregated or a dispersed form in the epithelial layer, lamina propria, and stroma. Even though immune cells are differentially distributed in each organ of the reproductive tract, the predominant immune cells are T cells, macrophages/dendritic cells, natural killer (NK) cells, neutrophils, and mast cells. B cells are rare in the female reproductive tract. NK cells in the endometrium significantly expand in the late secretory phase and further increase their number during early pregnancy. It is evident that NK cells and regulatory T (Treg) cells are extremely important in decidual angiogenesis, trophoblast migration, and immune tolerance during pregnancy. Dysregulation of endometrial/decidual immune cells is strongly related to infertility, miscarriage, and other obstetric complications. Understanding the immune system of the female reproductive tract will significantly contribute to women's health and to success in pregnancy.

The rural elderly population has social capital based on regionalism and kinship, which acts as a positive function in terms of their self-efficacy. Self-efficacy refers to the belief in one's own abilities. In general, elderly people with high self-efficacy maintain a healthy life and age successfully. This study examines how the rural elderly population perceive their self-efficacy and social capital and analyzes the role of social capital as a mediating variable. Social capital consists of 4 aspects; trust, norms, network and participation. For this study, data were gathered from 344 rural elderly people aged 60 years and over. The results of this study were as follows. According to the analysis of the structure equation modeling effect, the direct effect of subjective health status on self-efficacy, the indirect effect of the parameters of norms and the total effect were all statistically significant. Second, the direct effect of adult children's support on self-efficacy was significant, and the indirect effects of the parameters of trust, norms and total effect were all statistically significant. This study confirmed that social capital has a mediating effect on the relationship among the subjective health status of the rural elderly, adult children's support and self-efficacy. Furthermore, social capital had a positive impact on the self-efficacy of the rural elderly. Based on these results, a policy for making use of the social capital of the rural elderly should be developed.

This describes the level of knowledge and attitudes about HIV and their related factors among Cambodian adolescents. A cross-sectional design was used to examine the knowledge and attitude of 463 Cambodian high school students using HIV-KQ-18 (HIV-Knowledge Questionnaire-18) and HIV/AIDS Behavior Surveillance Survey Index (measuring attitude about HIV). The majority of the adolescents had a relatively low level of overall HIV knowledge (6.70 ± 3.66 (range: 0-16)) and held a very negative attitude (1.92 ± 0.87 points (range: 0-4)) toward the disease. Using multiple regression analysis, being male (β = 0.28, p < 0.001) and using YouTube as a social network service (β = 0.33, p = 0.035) were found to be independent factors associated with higher level of HIV knowledge. Study findings suggest the importance of informing policymakers and school nurses about the need to develop a and require a culturally sensitive specific health education program on HIV for Cambodian adolescents.

The purpose of this study is to explore the relative influence of psychological well-being and social support on the burnout of infant care teachers. Participants were 194 infant care teachers from 52 infant daycare centers in Gyeong-gi-do. Psychological burnout was assessed by the Maslach Burnout Inventory(Lee, 2011), psychological well-being was measured by the Psychological well-being scale(Cho & Cha, 2001) and social support was measured by the social support questionnaire(Bak, 1985). Date were analyzed using descriptive statistics and analysis, t-test, Pearson's correlation analysis, and multiple regression analysis. The major results of this study were as follows; First, there were differences in burnout in terms of marital status, work experiences, classroom operation type and income. Second, Infant care teachers' burnout was negatively correlated with psychological well-being and social support. Third, the most influential factor on infant care teachers' burnout was purpose in life, the second most influential factor was self-acceptance, the third most influential factor was emotional support, and the least influential factor was environmental mastery. Results of this study indicate that a psychological well-being enhancement program should be developed and emotional support from a social relationship network should be enhanced in order to prevent infant care teachers' burnout.
