How parks are to be made in the twenty-first century should certainly be different. This is the inevitable conclusion of the recent significant international design competition for Downsview Park in Toronto, 2000. The purpose of this critical study is to investigate new strategies for urban park design manifested in the proposals of that competition and to explore alternative ways of landscape design that could solve the recent crisis of urban parks. Tree City, the winning entry, and other final entries proclaim that city is park and park is city. In this sense, Downsview Park marks the end of traditional Olmstedian parks and the dichotomy between city(culture) and park(nature). Rem Koolhaas and Bruce Mau's Tree City will become the model for urban park design in the near future. There are three reasons for this. First, its design is a strategy rather than a form. We can interpret that Tree City is to be developed over time as directed by six strategies: grow the park, manufacture nature, 1000 pathways, sacrifice and save, curate culture, destination and dispersal. Second, it places faith in landscape as a revenue generator instead of a fiscal liability. Third, its implementation is possible with crude installation, requiring virtually no craft. Koolhaas and Mau intend for Downsview to be an environment that is never actually designed but is formed through natural succession, cultural action, and programmatical insertions. Rather than designed objects and formal solutions, their strategy is to allow the landscape to evolve with changing uses.

The purpose of study was understanding necessity of environment design for underground parking lot in residential design plan and grasping design plans of 'Activity Support' that considerate women, exclude women's unsecured feeling at underground parking lot. The inquiry analyzed 6 design plan in design competition that considerate women according to precede studies, a theory of CPTED, a design guide for wayfinding, and survey. A ramp, circulation, entrance, lighting, ventilation, and space design plan are proceed on this study The result are as below. First, a rectilinear figure ramp suits entrance plan on the circulation, but if it is not possible, cross-using of rectilinear and curvilinear figure ramp plan is desirable. Second, on the circulation plan, vehicles circulation plan and equality parking distribution plan got accomplished generally, and help senses of direction because it is planed network systemize. On a large scale underground parking lot, simplify parking circulation to convenience entrance and exit for weak in sense of direction. Third, the shape and material that‘s environmentally conscious will be in use to the entrance plan. As the first stage to the underground, artwork that women prefer can modulate the rejection of underground space. Forth, natural lighting system and ventilation can make the environment-friendly space, decrease the women’s rejection to the underground, it can also keep a natural watch on the space. Fifth, on the space design plan, it can use bright and comfortable design of wall and ground to decrease the women‘s rejection, also it is useful to the sense of direction. LED indirect lighting plan that 58.7% of women prefers on survey reflects women’s state of desire that bright and atmosphere. In addition, proper use of plans that subsidiary facilities, rest area with Sunken, and nature-friendly material can minimize differences of underground and ground parking lot.

본 논문에서는 IEEE 802.11 WLAN(Wireless LAN)의 MAC(Medium Access Control)인 DCF(Distributed Coordination Function)의 성능을 개선하는 알고리즘을 제안하고 이를 시뮬레이션으로 분석한다. IEEE 802.11 WLAN의 MAC에서는 데이터 전송을 제어하기 위한 방법으로 DCF와 PCF(Point Coordination Function)를 사용하며, DCF의 경우 CSMA/CA(Carrier Sense Multiple Access with Collision Avoidance)를 기반으로 한다. DCF는 경쟁 스테이션이 적은 상황에서는 비교적 우수한 성능을 보이나 경쟁 스테이션의 수가 많은 경우 처리율, 지연 관점에서 성능이 저하되는 문제점이 있다. 본 논문에서는 패킷 전송 후 충돌이 발생하면 윈도우 값을 최대 CW로 증가시키고 패킷의 정상적인 전송 후에는 윈도우 값을 서서히 감소함으로써 현재 WLAN의 망 상태정보를 계속 활용함으로써 패킷 충돌 확률을 낮추는 알고리즘을 제안한다. 제안하는 알고리즘의 효율성을 입증하기 위해 시뮬레이션을 수행하여 그 타당성을 제시하였다.

The increase in atmospheric carbon dioxide concentrations is known to be closely associated with climate change and global warming. In this sense, considering that facilities for appropriate education and experience on wood, which is a carbon pool, have been required, this study targets the Wood Cultural Experience Centers, which are in current operation, examines and evaluates their operation status and policy changes, and ultimately derives a successful positioning plan. To this end, it conducts a survey, and the results are as follows. First, as a result of the similarity analysis (KYST: Kruskal-Young-Shepard-Torgerson program) with facilities with leisure activities and educational functions, the Wood Cultural Experience Center have competition with natural recreation forests in terms of naturalness, and it has competition with the career experience center and youth training center in terms of experiential observation. Second, the result of positioning analysis of the attribute space map indicates that the Wood Cultural Experience Center is positively perceived in terms of such attributes as naturalness, experiential learning or recreation, and preservation of natural environment, but is negatively recognized in terms of accessibility, escape from daily life, and things to see.

It is getting more intensified with the competition among participating companies for global market share in major industrial fields. The situation is accelerating especially within the top 5 market share, and these include electric vehicles, semiconductors, chemicals, and shipbuilding industries. The key to the advantage over the competition within a strategic group is which company leads the innovation in the field. On-the-ground innovation refers to job-based innovation. This paper aims to analyze job unit innovation in the structure of empowerment, LMX, and job crafting. Existing studies on job crafting have suggested a causal structure based on job design in the traditional sense, and there are not many scholars who study the causal structure using a job situational model. Therefore, this paper takes an approach from the perspective of the job situation. As a result of the study, LMX showed a moderating effect on the relationship between autonomy provision and job crafting. While, in the relationship between meaing-giving and cognitive crafting, there is no significant moderating effect shown on the relationship between autonomy provision and cognitive crafting. Therefore, the results of the analysis in this study suggest that the meaning of jobs and participation in decision-making should be managed in an integrated way in structural and design areas, not just qualitative factors such as empowerment and leadership.

This study intends to review the development of Squid Angling Fisheries of Korea and Japan and subsequent changes in the fisheries regime as well as management conditions and to examine reorganization directions. Although catches and productivity are all increasing in Korea and Japan as the squid resource in the East Sea is improving, the number of fishing vessels and the conditions of fisheries management are showing a symmetrical relationship. The former is increasing in Korea and decreasing in Japan while the latter is aggravating in Korea and rather stable in Japan. And while the competition between the two countries for more fishing grounds and catches are not that serious since the resource is relatively increasing, the catch and price competition with other domestic fisheries is a more significant problem. Furthermore, even though light restriction is implemented in both countries in order to suppress over-competition, it is adopted as a means to curtail management costs and block over-investment rather than to adjust international or inter-fisheries circumstances. Japan has been implementing the TAC system on squid resources since 1998. However, it has a different meaning than as a resource management method in its original sense because it is based on the highest catch level of the past and takes into consideration the fishermen's management conditions. In case of Korea, it is necessary to establish a plan to strengthen its fisheries management competence to address its shrinking catch in the Japanese waters. The developments mentioned so far have appeared amidst the increase of squid resources, and if such conditions disappear, problems such as international allocation of catches and fishing seasons, access to fishing grounds, and domestic conflicts among different fisheries will emerge.

Because adolescents are much inflicted with the sense of obsession in endless competition with their feers the costume of the pop singers relieving this agony and anxiety is becoming the object of immitation more than that of any oother entertainer. In this perspective it was thought that it was very necessary to attempt to investigate what relationship sense of mental anxiety the costume singers recently have worn had with adolescents sense of anxiety. The anxiety questionnaire used by Chu Young-sook and Kim Jung-hui and the questionnaire drawn up as the result- of the pilot-test and the pre-test were used and the questionnaires drawn up by a total of 228 middle schoolgirls in seoul were used a sfinal data of annalysis. Of them the anxiety questionnaire was made up of 8 sub-scales such as classic·social·morbid·learning examination·school record·poverty·war and other to anxieties. in order to survey the overall content concerning the costume of the singers preferred by teenagers the other questionnaire presented three vaiables such as musicality fashionability and dance as the distinct characteristics of singers and hiphop style tidy style and sexy style of clothing as the style of clothing preferred of singers' clothing. The importance fashionability and imitability of clothing were investigated as variables in relation to singers' clothing behavior. The SPSS PC+ program was used as the analytic method of data which were tested by the frequency analysis Duncan's multiple anaylsis of variance t-test and so on. As a result of investigation middle schoolgirls having a high level of learning and examinatior anxieties preferred the singers excellent in musicality while middle schoolgirls having a lower level of classic anxiety preferred the singers excellent in fashionability and dance wearing the hiphop style of clothing. And it was shown that middle schoolgirls having a lower level of classic anxiety preferred the singers wearing the clothing of sexy style. In the light of these results it was shown that there was the correlation between anxiety and clothing preference. Accordingly it is thought that the purpose of this study was achieved to some exent.
