It should satisfy a variety of needs of consumer. The enterprise that hopes to get a winner in the present age brought in computer with useful tool to process information efficiently. The computer has displayed much more excellent computation ability than human to come up to their expectation and the growth of electronic technology was possible to make the computer's high-efficiency, economy and integration. No matter what we have a good economy and integration. No matter what we have a good information there is no meaning unless we are able to use it' so we should take it out by the our need. Therefore, this paper observes a future-oriented possibility of computer & Telecommunication in information society, information-oriented design environment and the trends of minimal and integrated computer. We will improve the designer's ability to develop a novel product that have the diversification of them using application, aiming at computer utilization and image identification design strategy of product in the age of network telecommunication.

The reason of the appearance of Internet is regarded as a milestone since we have shared information globally in a mutual way. The important thing on this point is what contents we choose for ourselves. The Internet could be meaningless unless we use it in a certain way, which ultimately means that the Internet has to deliver something valuable to us humans. Therefore, we have looked at how we can deliver and share humanity and emotion through the Internet, also how we can instill vital power into our real life, through the Internet. Fortunately, the current study must essentially be ongoing due to its nature with perhaps a multidisciplinary team brainstorming ideas. The reason for that is that not only could we find new business models for companies, but also find out new ways to appease the human mind in the modern age. In addition, as consumers needs become more specialized and diversified, companies are expected to face up to fierce competition with the help of innovative ideas. The ever-intensifying competition requires companies to cultivate new strategic tools in order to have new, powerful and sustainable comparative advantages. The goal of this research will be to explore ways of finding a new approach. Specifically, this research is about how to use the EVC(empathetic virtual character), which, this researcher believes, can deliver emotional benefits so as to make e-branding successful. According to reports, it has been proven that this new concept including the EVC can result in tremendous success. So the goal of this research is to explore the current situation and to anticipate the future concerning virtual characters.

Citizens'income has been increased along with the trend of rapid changes in society, and the quality of their lives has been improved as well. As much as the degree of increase of quality of life, the number of spectators for performing art events, etc. who desire to fulfill their needs for enjoyment of varied cultural performances have been increasing, and also a large number of spectators enjoys a variety of festivals being held in each provincial area as well as international events: we still remember such frantic rooting shown by citizens during 2002 World Cup drawing attention and interest of entire nation. There are always risks of loss of human lives if accidents occur as there sult of close-packed crowd gathered at the same time. Therefore, it is required to prepare adequate security measures in order to prevent various accidents before hand. It is hoped that this research work would be of help for further efficient and systematic security management for the performing arts centers or public theaters encouraging the event organizer and the private security firm and the Korea Private Security Association to exert great effort and investments in further projects for development of security technology. Also, it is required to build a performance culture to consider audience's safety first from the beginning to the end of the event on the basis of efficient security management. Furthermore, spect at or sare required to recognize the fact that safety in the site for performing arts should be guaranteed for everyone's sake, and, to achieve this, they are obliged to be more cooperative with the event organizer and the private security firm, forming a trinity all together, in order not to have safety threatening situations in the site of performing arts events.

The traction system has been mainly used for rehabilitation and correction of patients with spine or gait diseases in orthopedics or at home. Some problems could occur in human body when patients forced their training using the traction system. So it needs to measure a traction force and control the training time. However, most of products on market have no sensor measuring traction force. Thus we designed and made a sensor detecting traction force using strain gauge, amplifier for transition to output signal and experiment devices for performance test. We carried out experiment of a sensor detecting a traction force and measured electric responses of it with respect to traction loads. Maximum error was within about 1% for experiments in static condition and the average error was about 0.7% for experiments in dynamic condition. We concluded that it is possible to use the developed sensor for measurement of traction force since the maximum output variation of a sensor detecting a traction force was about 0.3% in $0^{\circ}C-60^{\circ}C$ temperature condition.

Leakage accidents in businesses dealing with hazardous chemicals can have a great impact on the workers inside the workplace, as well as residents outside the workplace. In fact, there were cases where hazardous chemicals leaked from many businesses. As a result, the Chemicals Control Act(CCA) was enacted in 2015, the Ministry of Environment introduced an Off-site Risk Assessment(ORA). The purpose of the ORA is to secure safety from the installation of the design of the workplace facilities so that chemical accidents of hazardous chemical handling facilities do not cause human or physical damage outside the workplace. In general, the ORA qualitatively determines where a protected facility is within the scope of the accident scenario. However, elderly who belong to the sensitive group is more sensitive than the general group under the same chemical accident effect, and the extent of the damage is serious. According to data from the Korea National Statistic Office, the number of elderly people is expected to increase steadily. Therefore, a quantitative risk analysis considering the elderly is necessary as a result of a chemical accident. In this study, accident scenarios for 14 locations were set up to perform emergency evacuation due to toxic gas leakage of Cl₂(Chlorine) and HF(Hydrogen Fluoride), and the effects of exposure were analyzed based on the evacuation velocity difference of age 20s and 60s. The ALOHA(Areal Locations of Hazardous Atmospheres) program was used to calculate the concentration for assessing the effects. The time of exposure to toxic gas was calculated based on the time it took for the evacuation to run from the start point to the desired point and a methodology was devised that could be applied to the risk calculation. As a result of the study, the relative risk of the elderly, the sensitive group, needs to be determined.

Lately due to the sudden growth of the construction of an apartment complex in domestic market, many construction companies are eager to provide various public facilities to increase the apartment distribution rate. An introduction of a fitness center is popularized as a part of such development. There has been a continuing development in a private fitness based on analyzing the user's data. However a public fitness is quite different from the private in terms of a user's classification, preference rate, the pattern of use, and location which requires a different facility plan. Nevertheless, all these days a public fitness in an apartment house has been developed without a specific facility plan based on relevant materials. It is worried that such development would cause the facilities not to function as appropriate resident facilities and sink to idle ones. Therefore the purpose of this paper is to make the standard considered in facility planning in future and the base to guide an applying method. In the paper the present condition of fitness centers inside apartment houses has been compared to analyze the progress of the existing facilities and the appropriateness of the organization and the structure division. The result of the research shows that public resident facilities is not the place to perform passive role for fixed activities but one to form a community through the human relationship based on the facility. Therefore a fitness center inside the apartment complex have to be designed to provide service and leisure space as one of main community facilities for residents. To obtain this purpose, when choosing facilities of an apartment complex, first of all the residents' standard of living, apartment size, residents' distinction rate of age and sex, the needs of the times should be fully considered Secondly, the size of each facility space have to be decided based on the practical data analysis in facility use such as space preference, average staying time. Also, future living culture requires the change of the function and space according to the change of social values, so continuing research and data analysis are required to related to fitness center inside an apartment complex in order to present systematic approaching method and the paper will be expected to be a little step toward it.

Ecotourism has the potential to boost the energy of a village as it pays keen attention to the ecosystem and the residents of the village. It is empowered by participation of and cooperation among stakeholders who are closely involved in ecotourism. However, many of them express difficulty in striking a right balance between development and conservation with regard to promoting ecotourism. Against this backdrop, this research paper investigates the structure of conflict that the stakeholders, especially those in Stork Village in Yesan County, South Chungcheong Province of Korea, experience during the process of establishment of government-led ecotourism. In addition, this study examines the problems of government-led ecotourism model and how they can be addressed. To analyze conflict structure, this paper used Q methods and found out that the budget-related stakeholders are largely divided into four groups as who; a) complain about how business profits are distributed; b) secure profits by expanding programs; c) consider human settlement, and; d) broaden people's participation. The biggest contributor to the conflicts is found that compensation was given discriminately to different jurisdictions. The second finding is that residents became less cooperative when the financial compensation did not live up to their expectation. For instance, they would demand the tourism facility physically expanded, repeatedly complain about the process of the work, and even accuse the government of degrading ecosystem. In other words, unless the compromise is reached with the residents regarding financial compensation, it could be difficult to encourage their participation and develop as a program-oriented tour. Lastly, the tour program needs to induce voluntary participation of the residents and deliver proper information on ecosystem and natural resources so as to last as sustainable ecotourism. The success of ecotourism will be subject to the cooperation of stakeholders in a region, conservation of our fragile ecosystem, and realization of sustainable growth through sharing economic benefits. This study looks into the cause of the conflicts of ecotourism sites and their structure. If this paper can bring about cooperation of stakeholders, the management and operation of ecotourism sites would be more sustainable.

Rhus verniciflua Stokes has been used for treatment of blood stasis and abdominal mass in Oriental medicine. Rhus verniciflua Stokes has been experimentally reported to exert antioxidant, antiproliferative, antithrombotic and apoptotic activities. In the present study, the antiangiogenic and in vivo antitumor activities of aqueous extract of processed Rhus verniciflua Stokes (Nexia) by heat were examined to elucidate its anticancer mechanism. Nexia showed weak cytotoxiicty against human umbilical vein endothelial cells (HUVEC) and Lewis lung carcinoma cells (LLC) with IC50 of${\sim}200\;{\mu}g/ml\;and\;>200\;{\mu}g/ml$, respectively. Nexia significantly inhibited the proliferation and migratory activity in vascular endothelial growth factor(VEGF) treated HUVEC. Furthermore, Nexia effectively suppressed the tumor volume in A549 nonsmall lung cancer bearing athymic nude mice, CanN. Cg-Foxn 1nu/CrljBgi up to 40.7% as well as tumor weight incised from LLC cells innoculated into the flank of C57BL/6 mice up to -50% compared with untreated control at a dose of 300 mg/kg. Taken together, these results suggest that processed Rhus verniciflua Stokes may inhibit the growth of Lewis lung carcinoma cells partly via inhibition of angiogenesis and can be potently applied to angiogenesis dependent cancers. However, it still needs a further research on molecular mechanism, angiogenesis animal study and clinical trial in future.

The more the population grow, the severer the shortage of a basic human needs such as clean water, food, energy resources and so on. Recently, we aware that deep sea water can be utilized to solve comprehensively food, energy and water problems. In this study, inhibitory effect of the deep sea water of east coast (DSW) on platelet aggregation were investigated using washed platelet and beneficial effect of the change of lipid concentration on serum at various time intervals for three weeks. In this study six groups of 6-month-old Sparague-Dawley rats were examined. An intact group served as controls (C-1D : breeding for one day, C-1W : breeding for one week, C-3W : breeding for three week). The fourth group (1D-DSW) supplemented with DSW for one day. The fifth group (1W-DSW)supplemented with DSW for a week. The sixth group (3W-DSW)supplemented with DSW for three weeks. The total cholesterol and triglyceride concentration on serum of supplemented groups with the DSW for one or three weeks were significantly decreased. The serum HDL-cholesterol level in the DSW groups were significantly higher than the level in the control group. The supplementation of DSW for one day did not appear to have such a beneficial effect on lipid level. The ability of platelet aggregation of supplemented groups with DSW was less than control group. These results suggest that supplementation with DSW is positively influence on lipid concentration and platelet aggregation.
