  • Better understanding of the complex factors leading to human diseases will be necessary for both long term prevention and for managing short and long-term health problems. The underlying causes, leading to a global health crisis in both acute and chronic diseases, include finite global health care resources for sustained healthy human survival, the population explosion, increased environmental pollution, decreased clean air, water, food distribution, diminishing opportunities for human self-esteem, increased median life span, and the interconnection of infectious and chronic diseases. The transition of our pre-human nutritional requirements for survival to our current culturally-shaped diet has created a biologically-mismatched human dietary experience. While individual genetic, gender, and developmental stage factors contribute to human diseases, various environmental and culturally-determined factors are now contributing to both acute and chronic diseases. The transition from the hunter-gatherer to an agricultural-dependent human being has brought about a global crisis in human health. Initially, early humans ate seasonally-dependent and calorically-restricted foods, during the day, in a "feast or famine" manner. Today, modern humans eat diets of caloric abundance, at all times of the day, with foods of all seasons and from all parts of the world, that have been processed and which have been contaminated by all kinds of factors. No longer can one view, as distinct, infectious agent-related human acute diseases from chronic diseases. Moreover, while dietary and environmental chemicals could, in principle, cause disease pathogenesis by mutagenic and cytotoxic mechanisms, the primary cause is via "epigenetic", or altered gene expression, modifications in the three types of cells (e.g., adult stem; progenitor and terminally-differentiated cells of each organ) during all stages of human development. Even more significantly, alteration in the quantity of adult stem cells during early development by epigenetic chemicals could either increase or decrease the risk to various stem cell-based diseases, such as cancer, later in life. A new concept, the Barker hypothesis, has emerged that indicates pre-natal maternal dietary exposures can now affect diseases later in life. Examples from the studies of the atomic bomb survivors should illustrate this insight.

  • This study is for the effective training strategy of human resources for the u-City construction to support the u-City human resource development plan of the Ministry of Land, Transport and Maritime Affairs (MLTM). One of the biggest problems concerning u-City is the shortage of advanced human resources for the u-City constructions. The characteristic of u-City makes u-City related human resources had knowledge of various fields including IT, GIS, construction engineering, urban planning and so on. But, there are only a few programs to train u-City related human resources. Therefore, this research established the objective of the training strategy for u-City human resource development as "the training strategy of human resources for the successful u-City constructions". To achieve this objective, four different core strategies are established like followings: (1) demander-oriented education, (2) regional balanced education, (3) integration education of u-City related subjects, (4) u-City related education infrastructure development. These 4 different core strategies can be achieved from 5 sub projects like followings: (1) demand estimation of u-City human resources, (2) u-City education from selected regional core universities, (3) u-City education from u-City human resource education centers, (4) online education and (5) construction of education infrastructures. These 5 interrelated sub projects can be preconditions of the successful human resource strategy development.

  • This study suggests a model for building governance system to develop and utilize human resources in Chungnam province. In particular, In the regional level of balanced development of human resources, the study tries to investigate alternatives to utilize regional human resources development by building and using a network between related organizations through their partnership and cooperative relations. This survey was conducted to 250 of personnel and experts who were in charge of human resources in diverse chungnam institutions through mail or e-mail from December in 2008 to February in 2009. As a result of the survey, the study shows that basic groundwork for the regional human resources development is poor in terms of forming the system and its plans, and the ties and cooperation between related organization, Therefore this study shows that in order to overcome the current situation and build the governance appropriate to Chungnam area, we need to consider different approaches for each regional organization stage by stage regarding the maturity in the governance.

  • Development of placenta is a complex process that is critical for the pregnancy and controlled by many factors including cytokines, hormones, growth factors and apoptotic molecules. Recently, it has been shown that progranulin (PGRN) functions in growth of embryo and trophectoderm as well as cell migration. To initiate understanding the role of PGRN in human placental development, we investigated the expression of PGRN mRNA and protein in early and late gestation human placentas, term cytotrophoblast cells and two choriocarcinoma cell lines, JEG-3 and Jar. Reverse transcriptase polymerase chain reaction identified mRNAs derived from the PGRN gene in all samples. Immunoblot analysis showed that PGRN proteins are present in early and late gestation human placentas with decreasing levels over gestation and that PGRN proteins are present in normal and transformed trophoblast cells. Immunohistochemical analysis using paraformaldehyde-fixed tissue sections taken from early and late stages of pregnancy showed that PGRN proteins are present in cytotrophoblast cells, syncytiotrophoblast and extravillous cytotrophoblast cells and that expression pattern of PGRN differed according to the stage of cell differentiation. The results of this study are consistent with the hypothesis that PGRN proteins have critical roles in placental development and suggest that PGRN may function in trophoblast cell growth and differentiation.

  • Main control room(MCR) man-machine interface(MMI) design of advanced nuclear power plants(NPPs) such as APR(advanced power reactor)-1400 can be validated through performance-based tests to determine whether it acceptably supports safe operation of the plant. In this work, plant performance, personnel task, situation awareness, workload, teamwork, and anthropometric/physiological factor are considered as factors for the human performance evaluation. For development of measures in each of the factors, techniques generally used in various industries and empirically proven to be useful are adopted as main measures and some helpful techniques are developed in order to complement the main measures. Also the development of the measures is addressed based on the theoretical background. Finally we discuss the way in which the measures can be effectively integrated and then HUPESS(HUman Performance Evaluation Support System) which is in development based on the integrated way is briefly introduced.

  • Previously, we identified albumin as an inhibitory factor in serum for cell adhesion of T cells such as human Jurkat T and primary cultured human T cells. In the present study, we found that other hematopoietic cell lines including U-937 human monocytes, THP-1 human monocytes, K-562 promyelocytic leukemia cells, and HL-60 human leukemia cells, also adhere to tissue culture flasks when serum is withdrawn, and albumin exerts an inhibitory effect on cell adhesion by those cells, implying that this inhibition is a common phenomenon in hematopoietic cells. Furthermore, we found that cell adhesion is inhibited by antioxidants such as (-)-epigallocatechin- 3-gallate (EGCG), morin, and a-tocopherol. Our results suggest that albumin may inhibit basal cell adhesion of hematopoietic cells and that the oxidative balance in the plasma may be important for cell adhesion of hematopoietic cells in vivo.

  • The purpose of this study was to examine the relationships among parent-adolescent communication, adolescents self-esteem, social development, and home environment. Home environment includes sex, father's vocations, mother's employments, parents educational level, and religions. 275 adolescents (186 males and 89 females students) were selected from middle schools in Seoul. The results indicated that there was no significant difference in parent-adolescent communication, adolescents self-esteem and social development according to environmental factors, such as parents' age, educational level, and religions. Also adolescents self-esteem was highly correlated with parent-adolescent communication, especially with mother-adolescent open communication. Finally, adolescent development of sociality was highly correlated with parent-adolescent communication, but not significant relationship with mother-adolescent reverse-functional communication.

  • Purpose: Research and development of human capital in countries bring sustainable development to the nations. Especially for developing countries, the attraction of foreign direct investment not only brings economic growth to the country but also contributes to improving human capital. This study aims to assess the impact of foreign direct investment on human capital in ASEAN countries. Research design, data and methodology: With data collected from ASEAN countries from 1990 to 2019, panel data analysis is performed with revised model types (the Pooled OLS, Fixed effect model, Random effect model and regression with Driscoll-Kraay standard errors). Result: The results of the regression analysis show that FDI has a positive impact on human capital. At the same time, the study also found that public investment in education also positively affects human capital; the life expectancy factor does not affect human capital. Conclusions: With this research result, the authors also proposed a number of solutions to improve human capital by attracting FDI and improving the efficiency of investment for the education of ASEAN countries. Besides, public expenditure on education also plays an important role in raising human capital. Therefore, investment in education should be promoted further in the future.
