Glaux maritima var. obtusifolia is distributed in very limited areas in South Korea and thus designated and protected as an endangered species. This study aimed to identify the diversity of vegetation in the Dangsa coast wetlands, the southern limit of G. maritima var. obtusifolia and to assess determinants of the vegetation and the importance of habitats. The phytosociological method of the $Z{\ddot{u}}rich-Montpellier$ School was used for vegetation classification and mathematical and statistical analyses were also conducted to analyze environmental factors and their relationship with the vegetation. The results of this study showed that there were 4 vegetation units in the Dangsa coast wetlands: Glaux maritima var. obtusifolia-Triglochin maritimum community (included three subcommunities), Puccinellia nipponica s.l. community, Beckmannia syzigachne-Isachne globosa community and Typha laxmannii-Phragmites communis community. It was also found that major determinants of the vegetation include moisture environment, soil depth, water level disturbance, vegetation height, community structure, etc. Glaux maritima was identified to grow most dominantly in the typicum subassociation of Glaux. maritima var. obtusifolia-Triglochin maritimum community, and the species compositions and dominant situations were observed to be similar to those in the southern limit in Japan, adjacent to South Korea. The assessment results indicated that the Dangsa coastal wetlands have a significant meaning from phytogeographical and syngeographical aspects, and contribute as a shelter for diverse species. It is required to establish conservation strategies to accurately determine the value of the wetlands of the Dangsa coast from various perspectives, and to protect and manage them.

This study was performed to acquire the information on the foodborne pathogen risk management programs in a couple of developed countries by the expert meeting and searching the information on the web. The backgrounds, strategies and effects related to microbial hazards of the foodborne pathogen reduction programs in fresh produce (US), Escherichia coli O157:H7 in ground beef (US), Salmonella in chicken, pork and eggs (Denmark), and Vibrio parahaemolyticus in seafood (Japan) were investigated for case study. A comparison among the pathogen reduction programs was conducted to find advantages and disadvantages and implications of the policies to bring out implications of the programs. A model for foodborne pathogen reduction program was developed based on both the CODEX risk management scheme and the case studies as follows; 1) preliminary risk management activities, 2) planing a foodborne pathogen reduction program, 3) option identification and selection, 4) implementation (conducting the each stake-holders role and applying the intervention methods), 5) monitoring activities, 6) interim review, 7) continuation or amendment of implementation method by the interim review before achieving the goal, and 8) final review and additional cost-benefit analysis if necessary. This proposed model according to the role of the stake-holders can be used to conduct microbial risk management programs in Korea in the near future.

Purpose: The purpose of this study was to examine self-transcendence, life satisfaction, and preference for end-of-life care in elderly patients. Method: This was a descriptive survey study. The study period was between August 2013 and October 2013 and included 208 elderly patients. Results: The average scores for self-transcendence, life satisfaction, and preference for end-of-life care were 2.79, 9.97, and 3.24, respectively. Statistically significant positive correlations were observed between self-transcendence and life satisfaction, decision making by health care professionals, spiritual area, family area. A positive correlation was observed between: (1) life satisfaction and spiritual area, (2) decision making by health care professionals and family area, and (3) decision making by health care professionals and pain area. Self-transcendence was a significant predictor of PCEOL. Conclusion: This study will provide basic information for use in the development of a program to encourage self- transcendence and life satisfaction, as well as to consider the elder's autonomy, pain control, and spirituality as important factors at the end-of-life care.

Enhanced index tracking is a problem of optimizing the objective function to generate returns above the index based on the index tracking that follows the market return. In order to avoid problems such as large transaction costs and illiquidity, we used a method of constructing a portfolio by selecting only some of the stocks included in the index. Commonly used enhanced index tracking methods tried to find the optimal portfolio with only one objective function in all tested periods, but it is almost impossible to find the ultimate strategy that always works well in the volatile financial market. In addition, it is important to improve generalization performance beyond optimizing the objective function for training data due to the nature of the financial market, where statistical characteristics change significantly over time, but existing methods have a limitation in that there is no direct discussion for this. In order to solve these problems, this paper proposes ensemble learning that composes a portfolio by combining several objective functions and a 3-stage portfolio selection algorithm that can select a portfolio by applying criteria other than the objective function to the training data. The proposed method in an experiment using the S&P500 index shows Sharpe ratio that is 27% higher than the index and the existing methods, showing that the 3-stage portfolio selection algorithm and ensemble learning are effective in selecting an enhanced index portfolio.

This paper comparatively considered how Korea and Japan address the concept of 'postwar' in descriptions of their literary history. In Japan, 'postwar' refers to the period after World War II (Asia-Pacific War). This word implies a variety of contexts such as collapse, poverty, confusion, calendar reform, reconstruction and restoration as well as a series of historical events such as war, war defeat, and American occupation; and so it has been treated in Japanese society a significant period. In the history of Korean literature, it is after national liberation that the word 'postwar' appeared; however, it has usually indicated 'the period after the Korean War.' The question is that although the term of postwar refers to periods after different wars, Koreans used the term of postwar also in the same way as Japan, and their concept of postwar overlaps with the concept of prewar or postwar used in Japan, and accordingly, side effects are produced that fail to grasp properly the independent characteristics and significance of the Korean War. In conclusion, the Korean War brought about contrasting effects on the history of Korean and Japanese literature. While the Korean War meant a start after the war in Korean literature, it became a turning point marking the end of postwar in Japanese literature. Such different perceptions on postwar also have major implications in that perceptions represent postwar discourses in today's Korea and Japan.

Objective : The purpose of this study was to investigate consensus relative to treatment strategies for psychosocial treatment in panic disorder, that represents one subject addressed by the Korean guidelines for treatment of panic disorder 2018. Methods : The executive committee developed questionnaires relative to treatment strategies for patients with panic disorder based on guidelines, algorithms, and clinical trials previously published in foreign countries and Korea. Seventy-two (61.0%) of 112 experts on a committee reviewing panic disorder responded to the questionnaires. We classified the consensus of expert opinions into three categories (first-line, second-line, and third-line treatment strategies), and identified treatment of choice using the Chi-square test and 95% confidence intervals. Results : For psychosocial treatment of panic disorder, individual and group cognitive behavior therapy (CBT) were recommended treatments of choice, and mindfulness based cognitive therapy (MBCT) was recommended as first line strategy. There was statistically significant consensus among experts regarding usefulness of each component of CBT and MBCT, for treatment of patients with panic disorder. Conclusion : Results, that reflect recent studies and clinical experiences, may provide the guideline for psychosocial treatment strategies for panic disorder.

Recently, quality problems of steel used for construction have been raised as a cause of building collapse and safety accidents. Accordingly, it becomes more important to secure quality through material management, procurement management, and construction management for construction used steels. However, the quality management for construction used steels is confined to technical production and process control. So, it does not provide a solution of various non-conforming steel products issues. Therefore, this study suggests improvements of the construction system to secure quality of the construction used steels. Through expert interviews, we identify the items for system improvement and derive the top priority items by considering utility through a structured Analytic Hierarchy Process (AHP). It also divided the respondents into enterprise and research groups to analyze differences, implications and future improvement issues and suggest a road map. It is expected that the priority items derived in this study could be useful as a basic data for making policy decisions to assure the quality of construction used steel.

Flight test systems should monitor various conditions in real time during flight tests and take safety measures in an emergency. The importance of ensuring test safety increases in more complicated and wider test environments. Also, due to the transition of wartime operational authority, many guided missile systems must be developed simultaneously. Early deployment and budget reduction by shortening the development and T&E periods are also necessary. Consequently, the risk of flight tests under the circumstance of inefficient test resources is increasing. To address this deficiency, a flight test system model using SysML was proposed in this study. The method of designing and verifying the test system is based on the agile shift left testing methodology of advanced T&E labs and utilizing a system reference model in the aerospace field. Through modeling and simulation analysis, early identification and correction of faults resulting from inconsistent test requirements can mitigate the risk of delays during the T&E phase of flight tests. Also, because the flight test system model was constructed using SysML, it can be applied to test various guided missile systems.
