Korea is rapidly becoming an aging society. This study aims to examine the existing conditions of outdoor living environments to assist a healthy lifestyle for senior citizens and to determine the most influential factor in a senior-friendly outdoor space as well as to suggest improvements in existing conditions focused on the prospective senior population. This study relied on two methods: a descriptive method of researching publications and related scholastic writings and an empirical study that included a survey of present conditions and interviews with the prospective seniors and senior citizens in Daejeon. Conditions of outdoor living environments for seniors were found to be more than adequate in general. But some factors evaluated as low must be carefully tailored for seniors. First, the study showed that seniors evaluated as highest the 'use of a walkway' for a stroll and stayed outside for 1~2 hours at a time. Many vehicles parked in walkways were the most inconvenient factors in going for a walk. Second, the study showed that the evaluation of outdoor space was about average and 'sociality' was evaluated as the lowest. Third, the study showed that men evaluated lower than women 4 items: 'use and convenience of a wheelchair', 'night lighting', 'discrimination of signage at nighttime' and 'trees'. Respondents above the age of 66 are more uncomfortable with items such as 'slippery walking surface', 'stair handrail', 'discrimination of signage at nighttime' and 'direction of apartment complex' while respondents above the age of 80 are more uncomfortable with items of 'slippery walking surface', 'stair handrail' and 'discrimination of signage at nighttime'. Fourth, the evaluation by existing housing patterns was statistically significant in 20 of 22 evaluated items. This means that residents in apartment complex evaluated as high these items in general. In this study, existing outdoor living environments for the elderly did not display any immediately serious issues in the overall evaluation items. Assuming, however, that the aging population will quickly increase in the next ten years, items which are evaluated as low in descriptive statistics and items which give inconvenience to the elderly above the age of 80 in particular will need to be the first areas to be improved.

People could possess different self-identity under virtual world from physical world because of anonymity of the virtual world and this difference could influence their behavior in the virtual world. Based on self-discrepancy theory, this research proposes that continuous use model in self-expression goal. We defined the difference bet ween actual self~identity and ideal self~identity in the virtual world as "self-discrepancy in virtual world", and the difference between actual self-identity in the physical world and actual self-identity in the virtual world as "cross-world self-discrepancy". Before testing hypothesis, we compare the actual self-identity in the online community with the actual self-identity in the physical world, and with ideal self-identity in the virtual world. We derived an index for two different types of self-identity in terms of Personal Self-identity and Social Self-identity through factor analysis. Our results show that online community members have a higher level of ideal self-identity than actual self-identity in online community, and they have better personal self-identity in online community than physical world while a lower level of social self-identity in online community than physical world. The results of the hypothesis testing analysis based on 300 respondents showed that "self-discrepancy in virtual world" negatively influenced perceived usefulness for self-expression while "cross-world self-discrepancy" positively influenced perceived usefulness for self-expression. The perceived usefulness for self-expression and ease of use positively influence both continuous use and knowledge contribution. Specially, the effect of perceived usefulness for self-expression on knowledge contribution is much bigger than the effect of ease of use. This study extends self-discrepancy theory to virtual worlds by suggesting various types of self-discrepancy and by applying the effect of self-discrepancies in online community. Also, this study extends technology acceptance model in the personal goal in terms of self-expression. This study hopes to offer practical insights by suggesting positive effect of self-discrepancy on behavior in the online community.

A network is an important model widely used in natural and social science as well as engineering. To analyze these networks easily it is necessary that we should layout the features of networks visually. These Graph-Layout researches have been performed recently according to the development of the computer technology. Among them, the Scale-free Network that stands out in these days is widely used in analyzing and understanding the complicated situations in various fields. The Scale-free Network is featured in two points. The first, the number of link(Degree) shows the Power-function distribution. The second, the network has the hub that has multiple links. Consequently, it is important for us to represent the hub visually in Scale-free Network but the existing Graph-layout algorithms only represent clusters for the present. Therefor in this thesis we suggest Graph-layout algorithm that effectively presents the Scale-free network. The Hubity(hub+ity) repulsive force between hubs in suggested algorithm in this thesis is in inverse proportion to the distance, and if the degree of hubs increases in a times the Hubity repulsive force between hubs is ${\alpha}^{\gamma}$ times (${\gamma}$??is a connection line index). Also, if the algorithm has the counter that controls the force in proportion to the total node number and the total link number, The Hubity repulsive force is independent of the scale of a network. The proposed algorithm is compared with Graph-layout algorithm through an experiment. The experimental process is as follows: First of all, make out the hub that exists in the network or not. Check out the connection line index to recognize the existence of hub, and then if the value of connection line index is between 2 and 3, then conclude the Scale-free network that has a hub. And then use the suggested algorithm. In result, We validated that the proposed Graph-layout algorithm showed the Scale-free network more effectively than the existing cluster-centered algorithms[Noack, etc.].

Objectives : Outpatient treatment orders refer to a mandatory social program in which mentally ill persons are ordered by the court to participate in specified outpatient treatment programs. This study aimed to investigate the factors that affect outpatient treatment orders and adherence to outpatient treatment in mental health patients. Methods : A survey on outpatient treatment orders and adherence to outpatient treatment was conducted on 60 psychiatrists between October and November 2016. The questionnaire items were drafted based on a literature review, and they were then evaluated by 3 psychiatrists and 1 law school professor before being finalized. Answers from the respondents were analyzed using descriptive statistics, and the median, maximum, and minimum values of the effectiveness scores of outpatient treatment orders were calculated. Results : Among the 60 psychiatrists, 45(75.0%) were aware of outpatient treatment orders; however, only 2 out of the 45(4.0%) had actually used the program in the last 12 months. The subjective effectiveness was very low, with only 40 points out of 100. Furthermore, of the readmitted patients, 37.7% had received continued outpatient treatment, whereas 53.1% chose to quit the outpatient treatment programs, meaning that the number of dropouts was higher. Among the discharged patients, approximately two-thirds were receiving continued treatment. With regard to follow-up for dropouts, majority of the responses were either "Not taking any action"(n=27) or "Not following up"(n=15). Only two respondents answered "Contact the community mental health promotion center," meaning that this response was very rare. Meanwhile, when asked about efficient measures to be implemented for dropouts, a vast majority of the respondents(n=30) selected the answer "Work with the community mental health promotion center." Conclusions : The outpatient treatment orders currently being administered were found to be ineffective, and the associated adherence to outpatient treatment was also found to be extremely poor. Hence, the effectiveness of the therapeutic interventions could benefit from institutional as well as administrative improvements. Community mental health promotion centers are expected to have an important role in the future.

The aim of this research is to find out the flows of mega-trends and design trends by analyzing the factors that influence trend and design trends in the late 20th century. Moreover, it is to forecast and recommend design color trends by evaluating color trends in design trends for the near future. Secondary and primary research were used in parallel. In the late 20th century, mega-trends were analyzed from secondary research based on PEST. Design trends were analyzed from case studies in fashion, space, product and visual design. On this basis, design color trends were analyzed. Also, color trends were forecast for the near future. The results are as follows. Firstly, the main trends in the late 20th century were 'female thinking', 'back to the nature' and 'heaven of peace'. Second, main design trends in the 1970s were modernism, post-modernism and high-tech. In the 1980s, with those of the 1970s, ecology was introduced In the late 1980s. In the 1990s, modernism rose again and ecology had an influence. The trends of 'female thinking' and 'back to the nature' controled the design in the early 2000s. Third, design colors in the late 20th century changed from Red to Purple Blue. Tones changed from 'grayish' to 'dull' Finally, it was forecast that Purple Blue, Yellow Red and Green colors with 'grayish', 'dull' and 'deep' tones were going to be used mainly in the near future. Also, achromatic colors with female and warm nuances would be reflected in design parts. This research will be very useful in that it has built a concrete database reflected on design trends forecasting in the near future by organizing academically a methodology to identify trends reflected on design and identifying relation between mega-trends and design trends based on analyzing factors that influence trend.

Purpose : Cancer, one of the major causes of death in Korea, tends to become chronic due to the rapid development of diagnostic and therapeutic methods. As a result, the number of home-based cancer patients is in the increasing trend. However, on account of the insufficiency of continuous and comprehensive cancer patient management system, a number of cancer patients are left in a defenseless state. This study was designed for need assessment of home-based cancer patient to establish the community-based health care system for the comprehensive and continuous health care service to improve the quality of life of cancer patients and reduce rare burdens of their families. Methods : Through making a survey for needs assessment toward the health care service, the 455 respondents among home-based cancer patients answered the given enquetes to analyze the management status and problems of home-based cancer patients Results : 1) Unsatisfaction rates of pain control is 25.5 percent for mild cases, 46.5 percent for severe cases. 2) According to the needs assessment of home-based cancer patients, most of the respondents want to receive economical support, alleviation for the pain and symptoms, and the information of health care and consultation. So these needs account for the main contents of the home-based cancer patient management plan. 3) In the aspect of the satisfaction rate for basic care need, most items account for $20{\sim}30%$ of satisfaction. And the proportion of need for special case is under 5%, satisfaction rate for special care need is about 50% of satisfaction. So the home-based cancer patients are not being cared sufficiently. Conclusion : According to the result of need assessment, many home-based cancer patients received inadequate pain and symptom management. And Satisfaction rate for basic and special care need is low. So development of comprehensive and continuous health care service to improve the quality of life of cancer patients and reduce care burdens of their families is very necessary.

The purpose of this study is to aesthetically approach a game, which was popular at home, through microscopic analysis on World of Warcraft. World of Warcraft(hereunder called WOW), which improved a game method of MMORPG that had been popular conventionally at home, from several angles, is suggesting new paradigm of MMORPG game. This study aims to propose new vision on game analysis by approaching this new method from the perspective of player. For this, it divided WOW into shift method, instruction implementation method, and communication configuration method, and analyzed this, respectively, by introducing a concept of empty time, empty space, and non-place, which was borrowed from Zygmunt Bauman's "Liquid Modernity". WOW's shifting method rather extends empty time, that is, the waiting time, contrary to the conventional MMORPG, which used a method of removing. Instead of maximally reducing boring, which becomes disturbance of a game, it is what overwhelmingly enlarges time that needs to be waited, thereby being what induces a sense of time, which a player experiences daily life, to the inside of a game. WOW's instruction implementation method offers one of hugely single map instead of zone-system necessary for map loading in the discontinued form. This minutely implements even a greatly insignificant place in playing a game, thereby stirring up a sense of travel, which explores there in reality. Finally, WOW's community configuration method makes a hunting-targeted group clear, which added a concept of hunting called the raid to the existing gild system. The raid, which is a large party of being bound to the inside of Instant Dungeon, clearly gives a performance role to each of party members, thereby allowing the identity in character to be connected directly to the identity of player. Through this, the player filled the suggested 'space' with experience, thereby being able to change it into 'place' that is significant to an individual.

Rapid accumulation of carbon dioxide in the atmosphere for the past century leads to acidify the surface ocean and contributes to the global warming as it forms acid in the ocean and it is a green house gas. In order to curb the green house gas emissions, in particular carbon dioxide, various multilateral agreements and programs have been established including UN Convention of Climate Change and its Kyoto Protocol for the last decades. Also a number of geo-engineering projects to manipulate the radiation balance of the earth have been proposed both from the science and industrial community worldwide. One of them is ocean fertilization to sequester carbon dioxide from the atmosphere through the photosynthesis of phytoplankton in the sea. Deliberate fertilization of the ocean with iron or nitrogen to large areas of the ocean has been proposed by commercial sector recently. Unfortunately the environmental consequences of the large scale ocean iron fertilization are not known and the current scientific information is still not sufcient to predict. In 2007, the joint meeting of parties of the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter, 1972 and 1996 Protocol (London Convention/Protocol) has started considering the purposes and circumstances of proposed large-scale ocean iron fertilization operations and examined whether these activities are compatible with the aims of the Convention and Protocol and explore the need, and the potential mechanisms for regulation of such operations. The aim of this paper is to review the current development on the commercial ocean fertilization activities and management regimes in the potential ocean fertilization activities in the territorial sea, exclusive economic zone, and high seas, respectively, and further to have a view on the emerging international management regime to be London Convention/Protocol in conjunction with a support from the United Nations General Assembly through The United Nations Open-ended Informal Consultative Process on Oceans and the Law of the Sea.

The question about whether a shorter workweek may increase employment has been a serious issue and been furiously debated among collective bargainers. The advocators recommend publicly that a reduction in standard working hours will provide benefits to the unemployed through the provision of new jobs, and also can improve the quality of life workers. The opponents argue that a shorter workweek will increase labor costs and induce firms to reduce their production levels, and consequently cut back their demand for labor. Although the debate is still continuing, considerable has been made toward achieving the goal workweek reduction. The analytical framework of this paper is a Putty-clay-model, in which the short-and long-term impacts of changes in working time on the employment associated with the interrelations of wages, prices, hourly labour productivity, the firm's labor demand, business cycle and economic growth etc. must be analyzed.

This study analyzed the comic "Monster" based on J. Lacan's psychoanalytic theory. J. Lacan advocated a new psychoanalytic theory through S. Freud's psychoanalytic theories and socio-cultural studies. The main theory of his theoretical background is the 'desire theory' which analyzed human desires. He distinguished human desires as desires and demands and had the basic proposition that 'human desire is the desire of the other'. J. Lacan (J. Lacan) studied in depth the relationship between oneself and others, which he defined by dividing it into an imaginary system (mirror stage), a symbolic system (Oedipus complex), and a real system (desiring subject). Based on these theories, the main purpose of this study is to analyze the comic "Monster" by Naoki Urasawa focused on the desire theory of J. Lacan based on psychoanalysis to examine what new meaning could be extracted. In order to analyze the comic "Monster", the qualitative research method was used and the method of analysis was the descriptive phenomenological method devised by Giorgi (1985). Through this analytical method, the background, characters, and symbols of "Monster" were analyzed and content analysis was performed based on the theory of Giorgi (1985) and the desire theory of J. Lacan As a result of the analysis of the meaning unit and components related to the desire theory through content analysis, the contents analysis was divided into four components: identification, reproduction of desire, alienation, and unique desire and freedom. The results of this study are summarized as follows. First, on the basis of psychoanalysis, "Monster" is classified into four elements, identification of twin characters, reproduction of desire, feeling of alienation and unique desire and freedom of characters based on desire theory of J. Lacan. Second, the characters analyzed by the desire theory of J. Lacan attempted to reproduce their desires through identification and projection of twins due to their traumatic experience when they were young. Also, the characters who felt alienated in the process of reproduction made a tragic ending to complete human desire and freedom to fill in their emptiness. This result shows that desire theory of J. Lacan based on psychoanalysis can be used as a new analytical theory, a comic analysis which suggested a new meaning. The results of this study suggest that a new field of research, a comic analysis using psychological theory, needs to be created and further studies in this field are required.
