The high intercept probability depends on optimization of the system, which consists of target detection, tracking system, missile system and so on. To reduce the complexity of global optimization of the system performance, simplification of the relative dependances of each sub-system is done and design parameters for DACS configuration are identified. The conceptual design process is addressed based on the requirement of the design parameters and new methodology is suggested for higher performance.

Purpose: In terminally ill cancer patients, accurate prediction of survival is necessary for clinical and ethical reasons, especially in helping to avoid harm, discomfort and inappropriate therapies and in planning specific care strategies. The aim of the study was to investigate prognostic factor of dying patients. Methods: We enrolled the terminal cancer patients from Kangnam St. Mary's Hospital from 2004 until their death. We observed symptoms shown in dying patients and assess 17 common symptoms shown in terminally ill cancer patients, performance status, pain and analgesic use. Results: Average period from hospitalization to death was 11.7 days. The most important prognostic factor is performance status (KPS), average KPS at enrollment is 48% and at last 48 hours is 25%. Physical symptoms that have significant prognostic importance are poor oral intake, weakness, constipation, decreased Karnofsky performance status, bed sore, edema, jaundice, dry mouth, dyspnea. Dying patients showed markedly decreased systolic blood pressure, cyanosis, drowsiness, abnormal respiration, death rattle frequently at 48 hours before death. Conclusion: If we assess the symptoms more carefully, we can predict the more accurate prognosis. The communication about the prognostic information will influence the personal therapeutic decision and specific care planning.

This study is intended to analyze flipped classroom learning activities, which have recently been spotlighted as a learner-centered teaching method in universities, from the perspective of cultural and historical activity theory. A survey and some participation observations were conducted with one professor and the students who participated in Educational Methods and Technology courses at A university. The components of the flipped classroom learning activities were analyzed based on the model of the activity system, and contradictions that appeared in the interactions between components were analyzed. Four implications were proposed for a more advanced flipped classroom learning activity system: the professor's and the learners' true identity recognition and role performance, strengthening the organic link between online and offline activities, support for alleviating the burden of teaching and learning preparation, and readjusting the system to support its smooth operation.

This paper explores changing concept of city in the context of globalization with innovation city and examines the characteristics of innovation city along with regional and national competitiveness. It is agreed that construction of innovation city by relocation of public institutions for balanced development of the country has valid logic. However, there are weak possibilities of innovation within the innovation city. Further more it is not a proper solution for the level up of national and regional competitiveness through this policy. The main logic is that physical relocation of institutions do not guarantee innovation of region through integration into globalization network resulting from the scale difference between nation and globe. Rather this paper suggests that regional innovation policy should performed in accordance with regional conditions and for the better competitiveness of nation and region, decentralization of power is needed. Then a region could have connection with global pipeline based on endogenous development power.

Hot spring water is underground water which naturally flows out to the earth's surface or is drilled for artificially and the water temperature should be higher than the region's average temperature for the year or underground water temperature of the earth's shallow strata of the region. Our nation stipulates that hot spring can be called if it is over $25^{\circ}C$. Generally, it is widely know that hot spring water has an effect on blood circulation, pain alleviation, soothing, and skin care and that its efficacy is mainly due to water temperature and a variety of minerals contained in water. The Onyang springs are the oldest spring district in our country and one of the most typical hot springs in this country. The current study found that there's no skin irritation through the skin irritation test applying hot spring water to cosmetic formulas, and that products using Onyang hot spring water showed an increase of 8.56% in epidermal water rate and a decrease of -67.74% in relative transepidermal water loss(TEWL), which indicates that cosmetics using Onyang hot spring water has an effecton skin improvement.

The purpose of this study is to find a reasonable solution that is compatible with the government's policy on calming the overheated housing market and the needs of prospective home buyers. For this purpose, this study analyzed the current state of the housing market and looked at the root cause of the people's desire to purchase housing. And this study suggested the need to introduce a super-long-term mortgage system that can help people choose whether to own or rent a house in accordance with individual preferences. The super-long-term mortgage system would be useful in that the majority of people who currently use mortgages prefer long-term loan products and that it could provide a chance to "get their own homes" by easing the monthly repayment burden for those who want to have homes. If the system is introduced in the future, it is necessary to make efforts for stable operation such as risk-hedge. In particular, the government should apply a limited application to end-users so that they can curb rising housing prices and contribute to stabilizing housing prices.

This work was carried out to investigate the anti-inflammatory effects of Paulownia coreana Uyeki on abirritant, atopy and acne skin. Paulownia coreana Uyeki has been used as a traditional medicine having anti-febrile, anti-inflammation effect in Korea, Paulownia coreana Uyeki loaves were extracted with 70% EtOH. Its superoxide anion radical scavenging activity and inhibitory effect on LPS-induced NO production were examined. The extract inhibitied the generation of NO and $PGE_2$ induced by LPS in the macrophage cell line (Raw 264.7). Consistent with the inhibitory effects on No and $PGE_2$ generation, the extract inhibited expression of iNOS and COX-2. In further study, it was found that the extract prevented $IkB-{\alpha}$ degradation, as demonstrated by western blot analysis of $IkB-{\alpha}$ protein level. However, the extract treatment did not affect cell viability at $100{\mu}g/mL$ concentration in both human skin fibroblast and Raw 264.7 cells in vitro. Thus, the present study suggests that Paulownia coreana Uyeki leaves extract have significant anti-inflammatory activity and potential as an anti-irritation material.

Recently, "aging in place" has become the principle philosophy of elderly housing policy in many countries. However, since there is ambiguity surrounding the universal definition of it, the meaning of AIP has been defined by political expediency. This study aims to discuss the meaning of AIP by examining the transition of elderly housing issues and policy in Japan. During the last two decades, the Japanese government has tried to launch a new elderly welfare system to shift the responsibility of elderly care from the family to the society and from the society to the region. And the focus of elderly housing policy has shifted from the promotion of three-generation dwellings to supporting the development of private residences. However, since the main goal has been limiting the welfare budgets rather than enhancing the quality of life, elderly housing issues have been reduced to a matter of choosing either elderly care facilities frequently located in suburbs or not. This paper suggest that we should pursue the true AIP idea in housing policy, and argues that to do so we need to consider AIP from diverse aspects such as temporal continuity, the range of space, the dynamics of place experience and the capability of communities.

Purpose: This study is aimed at understanding the volunteers' experiences and interactions with their corresponding teams during their participation in hospice care. More specifically, the study is to contribute policy-wise to development of hospice care in Korea by helping policy-makers and organizers and managers of hospice care provides better understand the importance of the meaning and roles of volunteers in hospice care. Methods: In-depth interviews and participant observation were performed with study participants who were selected from four different types of hospice agencies. Study analysis was conducted using "case study" as one of the rigorous qualitative research methods to develop "inter-" and "intra-" comparisons among the study participants. Results: Volunteers in hospice care were initially motivated by religion and faith, and the motivation grew stronger through the volunteer experiences. They emphasized that the essence of the hospice volunteering was motivation from religion and faith and something they do for themselves. They characterized their experience as a true service that is offered for free and a job that requires expertise. In addition, they achieved personal (internal) growth by reflecting on the meaning of "good death" and better understood the importance of respecting spiritual diversity. Conclusions: This study could help hospice officials offers better understand hospice volunteers' role and their importance. The study also provide practical implications and policy suggestions.

Ever since Korea and Vietnam reestablished diplomatic relations, the two countries'bond has become stronger than ever, augmenting the range of exchange between them in almost every possible field including politics, economy, society, and culture at such a high speed. Among many, an increase in number of Vietnamese immigrant women in international marriage is worthy of close attention. Since 2010, Vietnamese has topped the proportion of total foreign women married to Korean men, having surpassed Chinese. Nonetheless, the quick international marriage between Korean men and Vietnamese women, which usually happens without sufficient time to get to know about different cultures and languages, has not only raised problems for people concerned, but numerous social issues as well. Recognizing these problems, a number of government departments have provided various support on policies and legal issues toprotect multicultural families as a means of social integration and settlement support. Nevertheless, the support policies until now have been generalizing all of the immigrant women in international marriage as people subject to protection. Thus, considering every immigrant women as people in need, and trying to help them with various social issues have caused the government a high cost and low efficiency. This thesis emphasizes the point that through the cases of Vietnamese immigrant women in international marriage, there should be a specific support plan for specific people in need, reflecting various traits of different cultures and societies, in order to ease their settlement in Korea. Moreover, it suggests detailed plans for improvements on legal and institutional problems. Although the Vietnamese government forbids commercial agents for international marriage, many of agencies are still active and to help the immigrant women, who desire to return and resettle in Vietnam in case of divorce, this thesis suggests legal and institutional remedies for Korean and Vietnamese government. The composition of the thesis follows below: Part II on social and cultural traits of international marriage between Korean men and Vietnamese women. Part III on institutional problems and plans for improvements regarding settlement of immigrant women in international marriage. Part IV on legal and institutional problems and plans for improvements regarding divorced immigrant women and their return to Vietnam. Part V on conclusion. Divorce is not a flaw anymore nowadays, but in case of Vietnamese immigrant women ininternational marriage, an inadequate legal system hampers their resettlement process. Cases of not being ableto remove their own names from the family register due to poor financial and legal abilities are often identified and it is both the Vietnamese and Korean governments'duty to acquit their ethical responsibilities by seeking ways to institutionally and financially support them.
