This study was conducted to calculate the LCC of a apartment complex with a type of heating system, district heating and cogeneration system. For the purpose of analyzing LCC according to size of apartment complex, 500, 1,500 and 4,000 houses of model apartment selected. This research performs design of heating system and the life cycle cost analysis including an initial cost, energy cost, maintenance and operation cost, replacement cost and renovation cost during the project period(15years). According to the calculated results, 1) Initial cost of cogeneration system with 500, 1500 and 4000 houses is higher than district heating system each of 20%, 13%, 12%. 2) In case of cogeneration system, the payback period by electric generation is 5.21, 4.92 and 4.47 years and saving cost was calculated 29 billion won, 94 billion won and 262 billion won after payback period. 3) Cogeneration system LCC was 1.12, 1.07 and 1.06 times larger than district system with the size of apartment complex. According to the case of this study district heating system is more efficient than cogeneration system in terms of the reduction of LCC. 4) Gas Engine Co-generation System is more efficient than other systems because it can collect progressive part from electric charge progressive stage system. However, the efficiency is decreasing because of raising of fuel bills(LNG) and lowering of power rate for house use. Especially the engine is foreign-made so the cost of maintenance and repair is high and the technical expert is short. 5) District heating is also affected by fuel bills so we should improve energy efficiency through recovering of waste heat(incineration heat, etc.). Also, we should supply district cooling on the pattern of heat using of let the temperature high in winter and low in summer.

Recent disasters are a complex and growing trend. In order to effectively prepare for and respond to disasters that occur without notice, it is very important to use scientific information related to disaster and safety in addition to the standardized disaster safety information that is used. In this paper, we searched and selected major journals in the field of disaster & safety and conducted various network analysis studies using the classification scheme for development of integrated metadata for disaster & safety information developed through Disaster & Safety Information Sharing Platform R&D project as well as KSCD. Also, we have constructed and analyzed citation network, co-authorship network and keyword network through data identification and preprocessing of research paper contents. As a result of this study, based on the network constructed by information analysis unit, the network structure between core domestic and foreign journals, major research institutes, core keywords and individual information by disaster & safety type was identified in detail, and the analysis results were presented on a case-by-case basis.

Objectives: This study investigated the efficacy of Korean medical treatment for reflux esophagitis. Methods: We used Korean medical treatment (herbal medicines, acupuncture, herbal acupuncture, and therapy) to treat a hospitalized patient with reflux esophagitis. To evaluate the treatment, we measured the symptoms using the Reflux Symptom Index (RSI) and the Visual Analogue Scale (VAS) for heartburn, acid reflux, chest pain, foreign body sensations in the throat, chronic cough, hoarseness, and bronchial asthma. The generic health status was evaluated using the European Quality of Life Five-Dimension (EQ-5d) Scale. Results: The RSI and EQ-5d scores improved following treatment, but the VAS scores showed that only heartburn, acid reflux, and chest pain symptoms were relieved. Conclusions: This study suggests that Korean medicine may be effective for treating reflux esophagitis.

The ppuri industry is growing in technical importance due to the 4th industrial revolution and is growing steadily. However, securing skilled workers is hardly realistic, and foreign workers are increasing. The purpose of this study is to find organizational commitment on for improvement of in-role performance of foreigners and Koreans working in ppuri companies and to find ways to support differentiation through comparison between groups. The subjects of this study were foreigners and Koreans in the ppuri company. Through the survey, 393 valid samples were collected. We use structural equation modeling to verify the research hypotheses, and conducted a survey on the employees of organization with information security policy. The results showed that in the case of foreigners, balanced processing affects in-role performance through organizational commitment. In the case of Koreans, relational transparency, balanced processing, and internalized moral perspectives affect in-role performance through organizational commitment. The results of the analysis suggest a strategic approach to improve the in-role performance of each group.

Medical schools realize their social accountability in cultivating future doctors as decision-makers of medical care in the future society as an axis of society and carrying out communication, research, and medical service (medical care). This study summarized the social accountability status of eight medical schools in Korea, including the characteristics, activities, and programs in the sociocultural context. The data from the self-evaluation research reports of eight medical schools were classified and organized according to education, research, and medical care services. The medical schools offer related subjects, community service activities, and clinical practice, allowing active participation in local health promotion and disease prevention. Community health information research was conducted considering the difference between the local natural environment in which the medical school is located and the frequency of diseases. Medical schools and hospitals collaborated to conduct domestic and foreign health education volunteer activities. Social accountability must be prioritized, considering the importance of medical schools' functions and roles in a high knowledge-information society. Both doctors' medical capacity and competence to actively participate in developing medical care and health policies for the community should be strengthened.

This study is about the availability of Chinese internal arbitration institutions by Korean invested companies. Generally, Chinese internal arbitration institutions lack independence from government. However, because parties seeking an arbitration award have ways to get neutrality from internal arbitration institutions that guarantee party autonomy, these Korean companies can use Chinese internal arbitration institutions to resolve disputes in China. Special attention should be given to the following. First, because Korean companies invested in China are legally in the same position as Chinese companies, unless foreign-related factors intervene, when disputes occur with Chinese companies or individuals, the disputes correspond to internal dispute, and when it comes to choosing the arbitration institution, these Korean companies must choose either a Chinese internal arbitration institution or foreign-related arbitration institution. Second, most Chinese internal arbitration institutions still lack independence from government, which can influence the fairness of arbitration in the future. Therefore, Korean companies invested in China should think about alternative ways to get a minimum impartiality in arbitration cases. Third, the parties are allowed to choose arbitration rules freely in Beijing, Xian, Chongqing, Guangzhou, and Hangzhou arbitration commissions. Therefore, in arbitration cases, the parties can get impartiality by choosing arbitrators according to the arbitration rules which they agree on, or by choosing partially modified arbitration rules of those arbitration commissions. Fourth, in order to get an impartial arbitration award from Chinese internal arbitration institutions in China, it is important for Korean lawyers or arbitration experts -- fluent in Chinese -- to be registered in the List of Arbitrators of Chinese internal arbitration institution by way of signing a MOU between the Korean Commercial Arbitration Board, or the Korean Association of Arbitration Studies and arbitration commissions such as those of Beijing, Xian, Chongqing, Guangzhou, and Hangzhou which comparatively do guarantee party autonomy. Fifth, because application of the preservation of property before application of arbitration is not approved in China, in practice, in order to preserve property before application of arbitration, it is best to file another suit in China based on other legal issue (e.g., tort) independent from the contract which an arbitration agreement is applied to. Sixth, in arbitration commissions which allow different agreement regarding arbitration procedures or arbitration rules, it is possible to choose a neutral arbitrator from a third country as a presiding arbitrator via UNCITRAL arbitration rules or ICC arbitration rules. Seventh, in the case of Chinese internal arbitral award, because the court reviews the substantive matters to decide the refusal of compulsory execution, the execution rate could be relatively lower than that of foreign-related cases. Therefore, when Korean companies invested in China use Chinese internal arbitration institution, they should endure low rate of execution. Eighth, considering the operational experiences of public policy on foreign-related arbitration awards so far, in cases of Chinese internal arbitration award, the possibility of cancellation of arbitral award or the possibility to refuse to execute the award due to public policy is thought to be higher than that of foreign arbitral awards. Ninth, even though a treaty on judicial assistance in civil and commercial matters has been signed between Korea and China, and it includes a provision on acknowledgement and enforcement of arbitral award, when trying to resolve disputes through Chinese internal arbitration institution, the treaty would not be a big help to resolve the disputes, because the disputes between Korean companies invested in China and the party in China are not subject to the treaty. Tenth, considering recent tendency of conciliation by the arbitral tribunal in China and the voluntary execution rate of the parties, the system of conciliation by the arbitral tribunal is expected to affect as a positive factor the Korean companies that use Chinese internal arbitration institution. Finally, when using online arbitration, arbitration fees can be reduced, and if the arbitration commissions guaranteeing party autonomy have online arbitration system, the possibility of getting impartial arbitration award through them is higher. Therefore, the use of online arbitration system is recommended.

Republic of Korea is small nation that is comprised of 0.7% of the world population and occupying just 0.07% of the world territory. Despite this, Republic of Korea once again proved herself to be as the world's major economic powerhouse by becoming the world's 7th largest exporter in 2010. However, the reality is that Republic of Korea is still significantly concerned about the volatile economic nature and anxiety that is spread across the globe since the global depression that began at the end of 2008 and the financial crisis that has been threatening the Euro-Zone recently. This has resulted in the nation reaching the limitation in significant economic growth and limited creation of jobs within the nation and due to such circumstances, the nation is becoming more aware of the fact that she needs to pay more attention on the service sector and service exports if she was to see a more positive economic outlook in the upcoming future. This research is aimed to analyse the cost that is associated with the service export sector, by examining a number of enterprises in relation to the MICE(Meeting Incentives Convention Exhibition) industry which certainly has both direct and indirect influences on the service exports of the nation Further, the prime goal of the research is to encourage the SMEs of Korea, who have substandard experience associated to foreign exports, to intensify and increase service exports and also the goal extends to the degree to suggest appropriate assistance measures to aid these enterprises to achieve such goals. This research is fundamentally designed and based on the literature research associated with the MICE industry and also, this research is premeditated through the analysis of the case of exports to Vietnam. As the result of research, it has been found out that SMEs in the MICE industry and those of in service export sector are reluctant or even feel insecure to attempt any kind of export of their services mainly due to; the lack of foreign market information and also the lack of experience associated with service exports. Furthermore, it has also been revealed that the difficulty to estimate the validity and profitability of service the export is a significant factor withholding those enterprises from attempting any service export to the foreign markets. Henceforth, in order to aid and stimulate service export to the foreign markets by these SMEs (including those in association with the MICE industry), it is imperative to prepare an one-stop service export assistance program which would provide the information associated with marketing, law and legislation, taxation system and financial area in regard to the global markets.

Objectives: The objective of this study was to analyse the methods being used to control food intake and physical activity in RCTs of human obesity. Methods: A total of 21 randomized controlled trials (RCTs) were investigated. Nine of which were domestic studies from "http://oasis.kiom.re.kr" and the other of which were foreign studies from systematic reviews of RCTs on herbal medicine for treatment of human obesity. Results: According to domestic studies, "low calorie diet" were recommended in five cases of the domestic studies, "maintain current dietary habit" were recommended in two and no information on diet was two. Considering the seven cases where the information on diet was available, patients' food intake were checked at every visit in six cases. Only two cases among the six had been dropped owing to the violation of dietary habit by patients. Exercises were prohibited in two cases, "maintain current level of phisical activity" were recommended in three cases and, from the rest, no information was available. The level of physical activity were not strictly controlled by any means hence no drop out. According to foreign studies, "low calorie diet" were recommended in two cases, "very low calorie diet (less than 700 kcal/day)" in one case, "maintain current dietary habit" in two cases, "do not eat fat" in two cases and no information was available in the rest five cases. Exercises which concerns spending about 300 kcal/day was recommended in one case, "moderate exercise" were recommended in three cases, "maintain current level of physical activity" were recommended in three cases and no information available in the rest five cases. Conclusions: In order to improve the accuracy of RCT, for the dietary side, researchers should record patient food intake at every visit by means of 24-hour dietary recall methods. This can be supplemented by multiple choice survey that are designed to help patients to diagnose themselves more accurately leading to less bias. For the exercise side, it is highly recommended to confine the exercises to walking only so as to quantify the amount of physical activity more easily by using pedometer.

I researched the acceptance attitude to the multiculturalism of Korean people and the relationship between language and society through two Korean films, and . And I researched the language form in the multicultural families in the way conducting the survey targeting international marriage immigrant women. The content and conclusion in shortly are as in the following. (1) The acceptance attitude to the multiculturalism of Korean people is somewhat positive in such a case having no interests among themselves. (2) It depends upon the society and the culture for the foreigners to come into contact and learn the language easily. It means well-adapted to the certain society for the foreign workers to use status-language such as slang and jargon in the society. And this is the good example to show us the relationship between the language and certain society. (3) The language form of the multicultural families in Korea is mainly Korean, but two languages are used in order to communicate well with monolingual. This is called 'bilingualism', and according to the result of my research I think it is 'listening comprehension type bilingualism'. From this time forward it is urgently needed to develop the contents in relation to multiculturalism and the 'bilingualism' education program for multicultural families instead of the education of Korean being limited to communication itself in order to improve adaptiveness to multiculturalism in Korean society.

Nowadays most nations around the world including Korea have experienced absolute shortages of available urban space. To solve various problems of the city, each nation constantly tends to extend the underground space. However there is a serious problem in making use of the underground space. Especially new terrorism coming into existence after 9.11 terror turns into the so-called ‘soft target’ which has something to do with public transportation facilities available to most people. Good examples are like these: poisonous gas attacks in Tokyo subway in 1995, Daegu subway station fire in 2003, serial bomb blast of London subway in 2005. In spite of being a concern on incidents related to the underground space it is inevitable to utilize the underground space and the tendency is growing. But Korea lags badly behind in foreign countries in this field and so seeking measures is urgently needed. Therefore the aim of this study is to note visible damages stemmed from the domestic and foreign underground space and propose more effective and adequate measures. Safety measures of terrorism are associated to minimize damage out of terrorism and they are as follows. In the first place, preparing protective equipment for saving a life from fire attacks and poisonous gas is needed urgently. In the second place, counterpart management on the spot and systematic security training should be established in order to minimize injury. In the third place, fire escapes must be provided for a rapid evacuation of potential unspecified individuals. In the fourth place, building up a network of related institutions is required for a systematic omnidirectional counterpart. Finally the Korean government ought to take fast and appropriate actions for the injured and bereaved family of the terror incident.
