An Interest and development of an automation of the manufactory technology has been attempted actively in domestic and outside country. In particular, small and medium-sized manufactory are striving for the improvement of productivity through the automation of the plant. And manufactories to comply with the German's Industry 4.0 standard has attempted worldwide recently. But, This is not performed because a substantial investment-cost and development-cost and high efforts. Therefore, we attempted to design and mockup the SEB to enhance the productivity of the factory automation system. SEB, in conjunction with RFID and WiFi networks, expanding the communication range than the automation system of the existing plant, the transfer speed was also improved rapidly. And to be able to solve the existing factory automation system of vulnerability security of the problem, it can be solved by adding a section for user authentication.

This study analyzed annual final sample data from 159 companies based on firms selected as economic justice companies by Economic Justice Institute in Citizens' Coalition for Economic Justice in South Korea according to interest variables from 2005 until 2011. Analyzed results are as follows. First, higher scores in soundness and corporate social activities among CSR items suggested that corporate credit rating upgraded. This indicates that credit rating institutions give a good evaluation on their social activities and reflect them in credit rating assessment. However, environmental protection satisfaction and corporate credit rating showed the opposite results. Second, high objectivity and contribution to the economic development as well as supervision by giant auditors had substantial effects on higher corporate credit rating. In contrast, high soundness and supervision by giant auditors reduced corporate credit rating. Based on this outcome, it is estimated that there is a discriminatory response among CSR activities in terms of credit rating evaluation conducted by credit rating institution.

Objectives : Comparative review was rendered to evaluate strengths and weaknesses of two common treatment approaches of treatment based on syndrome differentiation and treatment based on syndrome differentiation from disease. A typical symptom of headache from hypertension was chosen for substantial approach of this review. Methods : Pros and cons of two different approaches to disease were evaluated based on literatures and texts focusing treatment based on syndrome differentiation and treatment based on syndrome differentiation from disease. Headache can be correlated with hypertension yet it can be induced by multiple other factors, and headache may/may not accompany hypertension. Hypertension is an example of treatment based on syndrome differentiation from disease and headache can be an example of treatment based on syndrome differentiation. Results : Treatment based on syndrome differentiation can give more autonomy and flexibility in approach to the disease, Intuition, experience, and traditional medical theory can be applied with ease. However, management and eradication of diseases are difficult and standardization of treatment is not easy among practitioners. Treatment based on syndrome differentiation from disease incorporated merits of both eastern and western medicines, achieving more evidence based diagnosis and treatment. Eradication and standardization of disorders are possible with the latter approach. Conclusions : Comparing two systems of treatment based on syndrome differentiation and treatment based on syndrome differentiation from disease with emphasis on hypertension and headache yielded medical values. Treatment based on syndrome differentiation from disease appears to be superior in medical values and effectiveness, but further evaluation and interest are needed to make advancement in Korean traditional medicine.

Dose response curves using absorbed dose to the biological effect are usually available in case of conventional X beam. However, absorbed dose is not consider in treatment planning for carbon beam such as heavy ions. Because the biological effects also depend on other quantities such as the local variation, which is often characterized by the linear energy transfer (LET). So LQ model cannot explain the entire response of fractionated carbon beam irradiation. The variation in LET with penetration depth leads to substantial differences in biological effect of carbon beam. And it is therefore essential in treatment planning to calculate not only the absorbed dose but also the LET to estimate the biological outcome of the radiation of interest. LET variation plays an important role in the fractionated irradiations. It is suggested that consideration of LET is necessary in biophysical model.

Protozoa of the genus Eimeria are the etiologic agents of avian coccidiosis, the most economically important Parasitic disease for the poultry industry. Coccidia multiply in intestinal epithelial cells of a wide range of hosts, including livestock in addition to poultry. Chemotherapy is extensively used to control coccidiosis. However, development of drug resistance by Eimeria parasites, the intensive cost and labor involved in the identification of new anticoccidial compounds and public awareness of drug residues in foods warrant alternative methods to prevent coccidiocic in the fast growing poultry industry. For these reasons, there is a great interest in developing vaccines against avian coccidiosis. Live Eimeria vaccines confer protective immunity, however a significant disadvantage of using these types of vaccines is their pathogenicity. Live parasites with attenuated pathogenicity also usually produce immunity but may revert back to a pathogenic form and may be contaminated with other pathogenic organisms. Killed Eimeria vaccines are safer but, unlike live attenuated vaccines, are not able to generate cytotoxic T lymphocyte responses. Recombinant vaccines are biochemically purified proteins produced by genetic engineering that consist of particular epitopes or metabolites of Eimeria. Unlike live attenuated organisms, recombinant vaccines do not possess as much risk and generally are able to induce both humoral and cell mediated immunity. DNA vaccines consist of genes encoding immunogenic proteins of pathogens that are directly administered into the host in a manner that the gene is expressed and the resulting protein generates a protective immune response. Although all of these different types of vaccines have been applied to coccidiosis, this disease continues to cause substantial morbidity and mortality in the poultry industry. Future development of an effective vaccine against coccidiosis will depend on further investigation of protective immunity to Eimeria infection and identification of important immundgenic parasite molecules.

A substantial literatures on environmental risk perception have emerged since the late 1960s. Most these works focus on how people form risk perception, on what people believe, on difficulties in communicating information about health, safety, or environmental risks to non-experts. In this study, questionnaire surveys were conducted to sample from stakeholders(general public, environmental specialist, governmental official, non-government officials, journalist) during March and Aprils, 2000. Total number of responses was 1,803 including 773 persons of general public, 353 experts, 390 governmental officials, 111 journalists and 176 NGO members. Risk perception on 26 environmental issues were statistically analyzed to relate with the need to regulate each issues, interest and knowledge, experience of hazard, satisfaction in environmental situation, etc. This research aims to aid risk analysis and policy-making by providing a basis for understanding and anticipating group responses to environmental issues and improving the communication of risk information among general public, lay-people, technical experts, and decision-makers. This study concludes that those who are in charge of promoting and regulating health and safety of citizens should understand how people perceive about and respond to environmental risk. Without such understanding, well-intended environmental policies of governments would be ineffective.

The scale of disasters is very large, also the influence of disasters is irreversible. Korean people has continuously learned how to deal with disaster management law. However, as time goes by after the many disaster, the concern with the disaster management by the people seems to become old and banal topic which nobody has interest in. If so, can it be said that our society is safe from the disaster? This study start from critical mind of asking this question. This study puts an emphasis on the problems such as following; To realize whole concept of disaster management provided in the basic civil defense law, the combined disaster management should be required to be established, the combined law should play a integral part for prevention for the disaster and should be a concrete basis of various laws for disaster management. Establishing a consolidated organization for disaster managing and united response organization is necessary. This consolidated organization is not temporary one such as civil disaster control headquarter but permanent one such as Disaster Management Office which controls an over all aspects of disaster management. Temporary organization should not be divided into natural calamity and man-made calamity but integrated one as a single control tower for all sorts of disasters. The police and army under fire fighting system should be reconsidered. It is necessary to make leadership system on the disaster place more substantial centered around present fire fighting system. To do so, more clear division of duty is required. The working condition should be improved so that all public servants in this agency can play their roles with pride and worth. The resource owned the existing administrative organization must be used by an appointment system. And to manage a large scale of disaster, it is necessary to have interorganizational network system which many specialized organization including volunteer group are integrated. And the natural disaster happen, many professionals and volunteers are distributed to the spots of disaster in the right man in the right place. Finally, citizen's consciousness about safety supervision needs to be recover.

The ultimate success of commercial applications of body scan data in the apparel industry will be consumers' substantial applications such as automated custom fit, size prediction, virtual try-on, personal shopper services (Loker, S. et al., 2004). In this study, we surveyed fifty consumers and forty-seven apparel industry workers about their recognition and interest in 3D body scanning and virtual try-on. The results are as follows: 55% of the apparel industry workers has recognized 3D body scanning as a convenient technology, but do not know how to use it. To the questions regarding virtual try-on, 53% of the workers give positive answers. The consumers have a more positive view on virtual try-on than the workers do. The workers predict that the application of 3D body scan technology to the apparel industry could offer customers helpful information in their clothing selection by using virtual images of various size and style, and increase mass production of MTM(Made-To-Measure). The answers from the male consumers in their twenties indicate that virtual try-on is useful by 88% on offline shopping and by 100% on online shopping. 53% of the workers and 68% of the consumers gave answers that just by virtual try-on they could judge the quality of the apparel products and purchase them. Absolutely 3D virtual try-on is an effective tool for online shoppers. 85% of the workers anticipate applications of the 3D body scanning also in 'body measurement', 'custom pattern development' as well as 'virtual try-on' in the near future. With the positive reactions and the stimulating interests in virtual try-on, the conditions of contemporary world encourage more active researches and wide usages of the technology in apparel industry.

An experimental study of thermal transport from a uniformly heated pipe to a pulsating flow has been carried out. Surface of the pipe is imposed with constant heat flux providing by electric heating band. This problem is of particular interest in the design of Stirling engine heat exchangers and in understanding the blood flow in the aorta. Temporal Variatiens of temperature and pressure inside the circular pipe are measured. The dependence of temperature distributions and heat transfer rate on the mean flow rate in the pipe and on the pulsating frequency is investigated in detail. The experimental results indicate that the measured temporal variations of temperature and pressure become nearly sinusoidal The amplitude of temperature variation near the pipe wall is much more substantial than that in core of the pipe. It is also found that the heat transfer rate is increased significantly as the frequency of the pulsating pressure is increased or the mean flow rate in a pipe is increased. The results obtained are also compared with those for non-pulsating flow circumstance.

The purpose of this study is to demonstrate the subjective structure of classes for college students. This study was conducted using the Q-methodology, and 33 various items were selected through a comprehensive review and revision process. Forty college students were selected for the P sample. The results showed four types of perception regarding college classes: Type 1 (Substantial Class-Focused Type) includes those who want to be a mature person through college classes; Type 2 ( Practical Class-Focused Type) includes those who have an interest in college classes to develop their work skills; Type 3 (Educational Environment-Focused Type) includes those who feel class size, communication with teachers, and the educational system itself are important; and Type 4 (Personal Competence-Focused Type), which includes those who feel that the right to take classes in order to increase their competence without mandatory classes is very important. Therefore, this study aims to investigate the types of individuals in terms of college class perception, as well as to provide reference materials to improve educational innovation for college students.
