근현대건축의 모폴로지 이론과 건축설계

김성홍,Kim, Sung-Hong 한국건축역사학회 2004 건축역사연구 Vol.13 No.4

This paper investigates morphological theory as an intellectual framework for research and design. The first part of the paper will review morphological studies in the fields of urban geography, urban planning and architecture, particularly in England from the 1940s to the 1980s. While urban geographers and planners were concerned primarily with town plans, building forms and land use, architectural theoreticians were more interested in the topological relationship between urban and architectural space. The underlying premises and principles of these two approaches will be reviewed. The second part of the paper will focus on typology in Europe and North America. The reinterpretation of typology by Italian architects helped to bridge the gap between individual elements of architecture and the overall form of the city. However, typological theory became less accessible in post-war England and the United States. After 1980, the debate on typology became muted by the onset of vague notions such as functionalism, bio-technical determinism, and contextualism. This paper will propose a redefinition of morphology as a heuristic device, in contrast with the dichotomic view of urban morphology and architectural typology. Morphology will be shown to combine the geometrical and topological; the intentional and accidental; the real and abstract; and a priori and a posteriori. The last part of the paper discusses the lack of comparative theories and methods surrounding the physical form of architecture and the city by Korea commentators. Empirically rooted facility planning, non-comparative historical studies, and iconographic criticism emerged as a central preoccupation of architectural culture between the 1960s and 1980s, a time when international debate on architecture and urbanism was most intense. This paper will give consideration to the built environment as a dynamic physical entity and space as an epiphenomenon of daily urban life, such that collaboration between urban designers, architects, and landscape architects is seen as both beneficial and necessary.

김성홍,Kim, Sung-Hong Korea Institute of Electronic Communication Scienc 2006 한국전자통신학회 논문지 Vol.1 No.2

병원 무선망에서 호 수락 방식과 보다 적은 범위 셀 환경에서 QoS를 보장하기 위해 통합된 페이징과 루프 정보 관리 캐시를 사용하는 Cellular IP 특성을 가진 Cellular-IP/PRC 네트워크를 제안한다. 제안한 호 수락 방식은, 이동 노드의 홈 기지국 용량이 충분하고, 인접 셀 이동 노드가 홈 기지국에서 호가 수락되었다고 가정할 경우 받을 간섭의 증가량을 고려해 통화 품질이 보장될 때, 홈 기지국은 새로운 호를 이동 노드의 송신 전력 예측에 기반을 둔 호 수락 방식이다. 병원 무선망 내의 페이징과 라우터를 관리하기 위해 사용되었던 PC(Paging Cache)와 RC(Routing Cache)를 하나의 PRC(Paging Router Cache)로 통합 관리하고, 모든 노드 내에 구성하여 운용토록 하고, 이동 노드의 핸드오프 및 로밍 상태를 효율적으로 관리 할 수 있도록 이동 노드에 핸드오프 상태 머신을 추가하며, 노드에서 관련 기능을 수행하도록 연구한다. 시스템 환경에서 통화량에 영향을 주는 인자를 분석하고 각 링크 통화권 및 불균형 정도를 예측하여, 하향링크에 의해 통화권이 제한되었는지를 판단하여 호를 수락 또는 차단하는 알고리즘 이용 총 송수신 전력을 기반으로 제안한 알고리즘을 응용해서 QoS에서 가장 밀접하고 중요한 호 차단 확률과 호 탈락 확률, GoS(Grade of Service), 셀 용량의 효율을 예측 처리하여 QoS 성능 개선을 나타낸다. In this paper, we propose for improving QoS in hospital wireless network using Cellular-IP/PRC(Paging Route Cache) with Paging Cache and Route Cache in Cellular-IP. Although the Cellular-IP/PRC technology is devised for mobile internet communication, it has its vulnerability in frequent handoff environment. This handoff state machine using differentiated handoff improves quality of services in Cellular-IP/PRC. Suggested algorithm shows better performance than existing technology in wireless mobile internet communication environment. When speech quality is secured considering increment of interference to receive in case of suppose that proposed acceptance method grooves base radio station capacity of transfer node is plenty, and most of contiguity cell transfer node was accepted at groove base radio station with a blow, groove base radio station new trench lake acceptance method based on transmission of a message electric power estimate of transfer node be. Do it so that may apply composing PC(Paging Cache) and RC(Routing Cache) that was used to manage paging and router in radio Internet network in integral management and all nodes as one PRC(Paging Router Cache), and add hand off state machine in transfer node so that can manage hand off of transfer node and Roaming state efficiently, and studies so that achieve connection function at node. Analyze benevolent person who influence on telephone traffic in system environment and forecasts each link currency rank and imbalance degree, forecast most close and important lake interception probability and lake falling off probability, GoS(Grade of Service), efficiency of cell capacity in QoS because applies algorithm proposing based on algorithm use gun send-receive electric power that judge by looking downward link whether currency book was limited and accepts or intercept lake and handles and displays QoS performance improvement.

Achieving very low phosphorus levels in treated wastewater will require the installation of additional treatment. Phosphorus removal experiments by chemical coagulation were carried out for the effluent of wastewater treatment plant in this study. TP total phosphorus or phosphate were highly related to the addition of PAC poly aluminium chloride which is one of the inorganic coagulants. But, organic polymer did not significantly affect the phosphorus removal efficiency. Polymer affected the flocculation of particle especially particle matter less than 10 micrometer so, the number of micro particles was decreased by polymer dose. Chlorination would not affect on chemical coagulation process and TP and turbidity could be effectively removed by the co addition of PAC and polymer.

A Study on the Evaluation of Multi-dimensional ASP Service Quality and Its Effects on User Satisfaction and Perceived Firm Performance

김성홍(Sung-Hong Kim),김진한(Jin-Han Kim),김길선(Kilsun Kim) 한국경영과학회 2008 韓國經營科學會誌 Vol.33 No.2

Quality has long been considered as an important factor in creating competitive advantage, and researches on quality have not been limited to off-line products but actively extended to e-services and information goods. However, given the nature of multi-dimensional aspect of quality, the systematic study on the quality of online service is still in its early stage. Especially, studies on the quality of ASP services have been rare in academic and professional journals despite the growth of ASP industry in its size and the rapid expansion in the range of application. In this paper, we clarified the multi-dimensional quality aspects of the ASP service using a Garvin’s framework (1984) which encompasses the service aspects of products, and developed a measurement model for ASP service quality. Then we empirically tested the effects of ASP service quality on user satisfaction and perceived firm performance using the data from 240 Korean small firms with less than 50 employees that had experienced the ASP service. Our results show that there are positive relationships among ASP service quality and personal performance, user satisfaction and perceived firm performance, and that product and service-related aspects of ASP service exert differential effects on performance measures so that the product-related aspects of the ASP service such as performance, features, reliability and conformance are considered to be more important in evaluating benefits from ASP services. Contrary to the approaches in literature where only the quality of online services is evaluated, our results emphasize the importance of differentiating product and service-related aspects of ASP service and provide a basis for more comprehensive evaluation of ASP service quality.

2000년 이후 도시건축의 대형화와 건축사사무소의 변화에 관한 연구

김성홍(Kim Sung-Hong) 대한건축학회 2009 대한건축학회논문집 Vol.25 No.10

The paper examines the changes in the size of architectural and urban projects, and the architectural design offices in Korea since 2000. Three research questions are raised specifically; the changes in the total building permit areas of each building types, the total floor areas of major urban architecture in Seoul, and the size of architectural design offices and their projects. The various statistics were comparatively analyzed; the statistics from OECD, the Ministry of Land, Transport, and Maritime Affairs, Seoul Development Institute, and surveys from 30 selected architectural design offices in Seoul. The paper discovers that the high percentage of construction investment driven by the government and public institution have lead to the amplification of urban architecture, and in turn to the polarization of architectural design offices into mega-size firm and small atelier type firm. The amplification and polarization of architecture raises the question of the diversity of urban culture, and the qualities of micro-scale architectural design, and therefore rigorous interdisciplinary research and discussion are required.
