  • The purpose of this study was to investigate the effect of employment related factors on household savings for precautionary purposes when controlling for financial security and to compare the results between the two different economic periods. A conceptual framework was developed based on the precautionary saving theory, the family stress theory, and previous empirical studies. As a self-insurance, a measure of security funds were developed and used as the dependent variable. Using data on working households in the 1992 and the 1998 Survey of Consumer Finances (SCF), a MLE estimation was conducted on the pooled data. The 1992 and 1998 data were used to reflect periods of economic recession and expansion, respectively. The results suggested that factors representing resources played the most significant role in determining the amount of security funds. Some of the employment related factors, preferences, financial security, and race were also significantly affected the amount of security funds. The results suggested that stable employment conditions were important for households to accumulate security funds. Households with more human resources and financial resources had a larger amount of security funds than those that had less human and financial resources. From the findings, implications for research, policies, and financial educators had been suggested.

  • Recent concerns over national and corporate competitiveness have stimulated a renewed interest in organization's performance. The organization's performance primarily depends on resources including human resources, budget, physical based resources, and so on. Especially because the relationship between organization's performance ;md individual capabilities is more evident in R & D organizations where the knowledge base is embodied in people, there has taken an increasing interest in the methodologies for measuring the capabilities of R & D personnel. This paper presents new methodological approach to measure the capabilities of R & D personnel. And the model is empirically applied to ETRI, a public R & D organization in Korea. On the basis of the results, the implications for R & D management are discussed, with regard to R & D business and human resources management.

  • With the advent of the era of the 4th industrial revolution, various factors such as economy, management, and culture are changing in modern society, unlike in the past. Among them, the main characteristic of management is the change from intangible goods to tangible goods, and companies are trying to pursue innovation such as introducing a new management method, converting from manufacturing to service, and expanding technology. However, with regard to human resources, which is becoming the most important for sustainable value creation in a changing era, efforts to enable practical innovation are lacking as they are still in a simple transition. Therefore, in this study, after recognizing the importance of human resources, we verified the relationship between the elements of the human resource in the service economy era according to organizational culture and organizational structure. The relationship between organizational culture and organizational structure by type was verified using the items of human resources, we verified the relationship between the elements of the human resource in the service economy era that were derived and verified in recent research. As a result, there were some significant differences in the image of human resources, we verified the relationship between the elements of the human resource by organizational culture and type of organization, but when the two factors were combined and interpreted, it was found that all of the human resources, we verified the relationship between the elements of the human resource in the service economy era were necessary. However, in order to overcome the limitation that the indicators of this study were limited, it is necessary to continue research through samples that consider various factors in the future and systematic classification by type of organization and industry by industry.

  • After industrialization has been started, mankind needs and consumes more resources. Now, the resources depletion is a serious problem in the Earth. However, there are infinite resources in the Space. Especially, the Moon is the closest planet and has much resources, including Helium-3 and rare earths, which are needed to human being in the future. Humanity needs to reside on the moon to harvest these resources. For the resident, much resources, such as food, construction, and industrial materials, are needed. However, to transport these resources to the Moon from the Earth, an astronomical cost should be consumed. Thus, research is underway to support human activities by procuring resources locally. This is called In-Situ Resources Utilization (ISRU), which is the essential technology for the space development. In this paper, the reason why ISRU is essential and the its status are introduced and future research projects will be explained.

  • China has a very large area, but the total and average amount of forest resources are always relative scarcity, retrospect the forest history, when the activities of human beings existed on the earth, the forest resources began to reduce gradually, it indicates that the amount of the forest resources have grate connection with the activities of human beings, especially from the foundation of New China, long term out-of- order logging and unsustainable development make the forest resources and ecological environment be destructed seriously. However, although Chinese forest resources still face a large number of complicated problems, it has already begun to recover and been into the right orbit through listing and analysis a series dates. Additionally, six key forest resources program's launching and the strategy shifting will take china enter a bright future.

  • The purpose of this study is to offer basic data of education to improve farm lives though investigating rural homemakers' life style. The results of this study are as follows : 1. The life structure of rural homemakers was classified into two structures as a material resources and human resources. The life style of rural homemakers was classified into systematical life style, traditional value style, social active style, and progressive active style. 2. The life styles of rural homemakers according to social population variance were as follows. The lower of age, homemakers whose family incomes more 30 million won or below 10 million won, who has religions, who employed in livestock were showed at very systematical life style. The homemakers who live in mountain village, higher the much age becomes, and the education level become lower, have showed traditional value style. Rural homemakers the lower of age, the higher incomes, composed of single parent + children who remain single were appeared social active style. Rural homemakers the lower of age, the more shortened farm life periods, who employed in livestock were appeared progressive active style. 3. Systematical life style was more affected by material resources structure, traditional value style was affected by material resources. And social active style was more affected by human resources, progressive active style was affected by human resources.

  • In this study, we elucidated the molecular mechanism of silymarin by which silymarin may inhibits cell proliferation in human colorectal cancer cells in order to search the new potential anti-cancer target associated with the cell growth arrest. Silymarin reduced the level of c-Myc protein but not mRNA level indicating that silymarin-mediated downregulation of c-Myc may result from the proteasomal degradation. In the confirmation of silymarin-mediated c-Myc degradation, MG132 as a proteasome inhibitor attenuated c-Myc degradation by silymarin. In addition, silymarin phosphorylated the threonine-58 (Thr58) of c-Myc and the point mutation of Thr58 to alanine blocked its degradation by silymarin, which indicates that Thr58 phosphorylation may be an important modification for silymarin-mediated c-Myc degradation. We observed that the inhibition of ERK1/2, p38 and $GSK3{\beta}$ blocked the Thr58 phosphorylation and subsequent c-Myc degradation by silymarin. Finally, the point mutation of Thr58 to alanine attenuated silymarin-mediated inhibition of the cell growth. The results suggest that silymarin induces the cell growth arrest through c-Myc proteasomal degradation via ERK1/2, p38 and $GSK3{\beta}-dependent$ Thr58 phosphorylation.

  • In this study, we evaluated the effect of branch (STB) and leave (STL) extracts from Sageretia thea on ${\beta}$-catenin level in human colorecal cancer cells, SW480 and lung cancer cells, A549. STB and STL dose-dependently suppressed the growth of SW480 and A549 cells. STB and STL decreased ${\beta}$-catenin level in both protein and mRNA level. MG132 decreased the downregulation of ${\beta}$-catenin protein level induced by STB and STL. However, the inhibition of $GSK3{\beta}$ by LiCl or ROS scavenging by NAC did not block the reduction of ${\beta}$-catenin protein by STB and STL. Our results suggested that STB and STL may downregulate ${\beta}$-catenin protein level independent on $GSK3{\beta}$ and ROS. Based on these findings, STB and STL may be a potential candidate for the development of chemopreventive or therapeutic agents for human colorectal cancer and lung cancer.
