The highest fatal accident ratio was recorded in the construction industry. According to the industrial insurance premium rate & business type example, among the construction industry, the architectural work has the highest fatal and loss time accident ratio. Previous literature has investigated various aspects of accident occurrence and prevention in architectural work. However, those studied were limited in that they only focused on the fatal accident without considering the loss time accident. But non fatal accidents were recorded more than 50 times of fatal accidents. Therefore non fatal accidents must be controlled to lessen industrial accidents. Based on this, the goal of this study was to investigate the nature of the loss time accident and derive the risk index of work type in architectural work. In this study, opinions of safety experts were gathered and the risk index of work type was derived using AHP(Analytic Hierarchy Process). And verification was accomplished by comparing the results of this study with the risk index derived by analysis of accident records. Results showed that the risk index of work type was significantly higher in steel frame work, temporary installation work, earth & foundation work, facilities work, concrete work. And statistical analysis for verification showed that coefficient of Pearson correlation was 0.686 and P-value was 0.001.

This study aims at understanding both the mechanism of new town's competitiveness and its normative pursuit. For the purpose the study steps as follows; (1) Defining operationally cities' competitive power by means of analytic interpretation of substantial nature involved in the preceding studies, (2) Finding some lessons for the desirable development suggested from the history of new town construction in England, France and Japan, where the spatial needs for solving urban problems were exploded after the Second World War, (3) Focusing to agendas regarding development, for example, sustainable development, (4) Recognizing differences between competitiveness of cities and that of new towns and finally (5) Building the model of new town competitiveness, which explains what makes the competitiveness and what kind of effort are necessary for acquiring the advantage. As the result of the process this study concludes that the competitiveness is caused by, or composed of 4 factors. They are Self-sufficiency, Identity, Innovativeness and Sustainability. This frame can be named SIIS-model of new town competitiveness. But there should be contingent and elastic approach in adaptation of these factors to a specific new town, considering its own goal, scale and other situation. The model established in this study is expected to be a analytical frame for the follow-up studies on finding problems and seeking directions of new town development in our country.

본 논문에서는 프레임 기반 패킷 전송 스케쥴링을 위한 지연 감축 방안을 제안한다. ATM과 같은 초고속 통신망은 사용자에게 대역폭과 패킷 지연과 같은 성능을 보장하여야 한다. 스케쥴링 방법에 있어 프레임 기반 구조는 사용자에게 요구되는 대역폭의 지원과 간단한 레이트-제어 방법을 제공하지만 나쁜 지연 특성을 가지게 된다. 본 논문에서 제안한 지연 감축 방법은 HRR (Hierarchical Round-Robin)과 같은 계층적 프레임 구조를 사용하지만 지연 특성을 좋게 하기 위해 고정된 우선순위를 갖는 라운드 로빈 방식을 사용하지 않고, 동적으로 우선순위를 변화시킴으로써 광대역과 협대역 연결간의 지연에 있어서의 불평등을 해소하였다. 해석적 비교 및 모의실험 결과 제안된 HFIFO 방법이 기존의 HRR과 같은 프레임 구조의 장점을 그대로 따르면서, 연결간 공정한 지연품질 제공하며 전체 지연 값을 줄일 수 있음을 알 수 있었다.

There is the commonness between I-Ching of Asian scriptures and Analytic Psychology of C. G. Jung as the conjunction of opposites of yin and yang. I-Ching has the base of the Great Absolute(太極) as yin and yang. Jung's psychology has the basic structure of opposite contents of psyche. The former wants to find the proper answer for the situation as fortune book, the latter realization of personal psyche. At this basis to approach I-Ching through the Analytic Psychology can be connected with the screening its inner system and structure in the frame of depth psychology. Basically I-Ching is the scripture about the good or ill luck, regret and stinginess. All of them are related with the psychology of human beings practically. I-Ching as the main scripture of Asia has the core theme concept of the mean (中). Previously mentioned the good or ill luck, regret and stinginess are included into this as the large view point. The best decision between the given situation and the fortune teller pursues the mean(中) path of both. Jung's psychology also attaches importance to the proper balance among personal conscious, unconscious and his surrounded situations. Goodness is relied on the mean, healthy psyche the harmony with the psychological and real situations of a person. But this balance and mean cannot be achieved without any reason but by the result of the conjunction of opposites. The opposites are the Ch'ien(乾, the Creative, Heaven) and K'un(坤, the Receptive, Earth) as yin and yang in I-Ching and the conscious and unconscious in Jung's psychology. These can be opened to masculine and feminine, psyche and matter, transcendent and existence and casuality and acausal synchronicity. Conjunction of these opposites can develope and create the new conscious and creative situation. Finally yin and yang from the Great Absolute and conscious and unconscious from Self become the opposites and go through necessary step of separation and sublimation for the creation of new level. In the Great Absolute there are yin and yang and yin the latter contains the cyclic process which can make the former renew. Conjunction of opposite in Jung's psychology also go through the similar process as the Great Absolute of yin and yang.

This research was conducted to suggest some directions for desirable urban green space planning through 1) establishing a new classification system by examining the existing concept, problems and characteristics of green space and 2) defining the essence of green space environment and finding some analytical and evaluative methods through a clear establishment of functions, indicators of green space. An analytical technique of green space, in which the coexistent relationship of human and other organisms was emphasized, was tried in order to realize urban green space planning. Based on the relevancy between green space and human being, green space was classified into green space for existence green space for utility, green space for both of existence and utility. The ratio of green covered, the ratio of greenery within the frame of vision, and the ratio of green volume in green space for existence was used as analytic and evaluative indicators.

This study intends to understand the visual experience of architectural space generated by users' movement based on the interpretation of visual properties. An analytic theory of Isovist is suggested for the objective and comparable measurement for such visual experience, and a computer program for the analysis has been proposed as well. By using the analytical theory and computer program, eight houses designed by Adolf Loos and Le Corbusler are analyzed for the purpose of understanding the visual characteristics of the Modern Architecture and the contemporaries. The result shows that, while the architectural space of Loos emphasizes personal privacy as for being livable spaces, the architectural space of Corbusier emphasizes users' movement as for including diverse visual arrays. These commensurable results exhibit that the analytical tool and research frame suggested in this study can be a competitive tool for such analysis.
