This study investigates ethical fashion consumption factors and corporate social responsibility (CSR) factors to segment consumer groups by ethical fashion consumption (EFC) and identify differences of EFC groups in the perception of CSR and demographics. I surveyed 390 people over age 20 in February and March, 2017. Data were analyzed with factorial analysis, cluster analysis, ANOVA, LSD, Chi-square, Cronbach's ${\alpha}$, using SPSS 20.0. The survey showed. 1) Five EFC factors (boycott/active purchase, donation/environmental protection, saving, legal consumption, and recycle) were extracted. 2) Four CSR factors (responsibility for stakeholder, ethical/environmental responsibility, social/charitable responsibility, and economic responsibility) were extracted. 3) EFC consumers were classified into four segments (low ethic, recycle, legal, and high ethic). 4) The perception of CSR factors was different among EFC groups. 5) The distribution of age level, education level, occupation, monthly purchase cost of clothing, and religion were different among EFC groups.

The half of njuries by carrying-unloading machinery was injuries due to crane. The purpose of this study was to analyze present condition of injuries by the crane, to investigate hazard management model, injury prevention technique, and to suggest safety countermeasures of crane working. The hazard management model is composed of 5 rules and 10 methods. The rules are to remove, separate, protect, make up and correspond. Prior to this crane countermeasures, general protection for head, foot and hand are needed. Hazard prevention affects on industrial management economically and psychologically. The preparation of safety countermeasures are very important for the prevention of industrial injuries, The countermeasures are setting-up of safety culture, active and rationale safety education. As the industrial safety and health system should be performed for the employees' health and life, the industrial competitive power and productivity would be improved.

Energy foundations and other thermo-active ground structure, energy wells, energy-slab, and pavement heating and cooling represent an innovative technology that contributes to environmental protection and provides substantial long-term cost savings and minimized maintenance. This paper focuses on earth-contact concrete elements that are already required for structural reasons, but which simultaneously work as heat exchangers. Pipes, energy slabs, filled with a heat carrier fluid are installed under conventional structural elements, forming the primary circuit of a geothermal energy system. The natural ground temperature is used as a heat source in winter and a heat sink in summer. The geothermal heat pump system with energy-slab represented very high heating and cooling performance due to the stability of EWT from energy slab. However, the performance of it seemed to be affected by the atmospheric air temperature.

Panax ginseng, also called Asian or Korean ginseng, has long been traditionally used in Korea and China to treat various diseases. The major active ingredients of P. ginseng are ginsenosides, which have been shown to have a variety of therapeutic effects, including antioxidation, anti-inflammatory, vasorelaxation, antiallergic, antidiabetic, and anticancer. To date, approximately 40 ginsenoside components have been reported. Current research is concentrating on using a single ginseng compound, one of the ginsenosides, instead of the total ginseng compounds, to determine the mechanisms of ginseng and ginsenosides. Recent in vitro and in vivo results show that ginseng has beneficial effects on cardiac and vascular diseases through efficacy, including antioxidation, control of vasomotor function, modulation of ion channels and signal transduction, improvement of lipid profiles, adjustment of blood pressure, improvement in cardiac function, and reduction in platelet adhesion. This review aims to provide valuable information on the traditional uses of ginseng and ginsenosides, their therapeutic applications in animal models and humans, and the pharmacological action of ginseng and ginsenosides.

It was attempted to observe the effect of garlic on the hepatic glutathione s-transferase and glutathione peroxidase activity in this study. Glutathione s-transferase (EC 2.5.1.18) are thought to play a physiological role in initiating the detoxication of potential alkylating agents, inclnding pharmacologically active compounds. Glutathione peroxidase (EC 1. 11. 1. 9) might play an important role in the protection of cellular structures against oxidative challenge. The activities of glutathione s-transferase and glutathione peroxidase in rat liver were increased by the treatment of garlic juice. Allicin fraction, heat-treated allicin fraction and garlic butanol fraction markedly inhibited glutathione s-transferase activity in vitro, whereas glutathione peroxidase activity was significantly increased in heat-treated allicin fraction and garlic butanol fraction.

This study aims to find out the way of revitalizing of natural riverfront space in terms of ecological aspect. At the first part, theoretical made in terms of concept, planning aspects and techniques which were main bases for the study. It begins by explaining the concept of ecological riverfront space, the main aspect and techniques of its planning. After this, it analysis eight cases(four cases in Korea, Swiss, Germany, America and Japan) in terms of the objects, planning techniques and the results of development. It continues by making detailed analysis according to four objectives like 'protection from flood', 'quality of the river', 'ecological preservation' and 'active usage of riverfront space'. It ends by evaluating the relationship between objectives and the planning which will be adapted to the future development of riverfront space with ecological aspect. In conclusion, hereafter will propose desirable design-direction for revitalization about riverfront space about ecological aspect design in urban.

1.Power utilities and CRIEPI are very active in almost all aspects of power systems research. 2.About 50% of research activity of CRIEPI is made under the joint work with power utilities. 3.Research motivation of manufactures are mainly stimulated by the need of power utilities and manufacturers are closely collaborating with power utilities. 4.Main effort of universities is concentrated upon the theoretical aspects of network analysis and the means of stability improvement. Univer sities are doing research rather independently of industry unless inexceptional cases. 5.Universities are making a significant contribution to the exploration of new horizon of power systems engineering, namely, in the research on the social impact on the future of power system. 6.Current main interest of power systems reserch is centered around the stability problem and power system operation and control. Research activity in power system planning is rather low as compared to that in these two major fields. A similar statement holds for the analysis of electromagnetic transients and short circuit analysis. However a new research field is sprouting in the area of power system protection.

The basic study on laser triggered lightning was carried out for the active protection of lightning in power transmission system. The lengths of generated plasma channels were simulated numerically for variations of energy and pulse width of CO$_{2}$ laser by Runge-Kutta-Gill method. As results, the effective lengths of plasma channels were 2.3m, 2.67m and 3.4m respectively for energy of 45J, 60J and 100J of CO$_{2}$ laser pulse with pulse width of 50nsec using focusing mirror with focal length of 10m. And also the effects of pulse width of first pulse and tail pulse of CO$_{2}$ laser on the length of plasma channel were examined.
