In this paper we propose a new CBL-based floorplan method that accommodates pre-placed blocks. We identify the problem of the previous CBL-based pre-placed block floorplan method, and suggest the solution method of this problem. In our method, CBLs consisting of only free blocks are perturbed and maintained during the simulated annealing. Pre-placed blocks are inserted during packing in such a way that the topology of the CBL after insertion of a pre-placed block resembles the topology before insertion. Thus, even with the inclusion of pre-placed blocks, the searching effort via simulated annealing yields acceptable results. Experimental results show that our floorplan method places pre-placed blocks effectively and efficiently.

As VLSI technology scales to nano-meter order, relatively increasing global wire-delay has added complexity to system design. Global wire-delay could be reduced by inserting pipeline-elements onto wire but it should be coupled with LIP(Latency Intensive Protocol) to have correct system timing. This combination however, drops the throughput although it ensures system functionality. In this paper, we propose a computation method useful for minimizing throughput deterioration when pipeline-elements are inserted to reduce global wire-delay. We apply this method while placing blocks in the floorplanning stage. When the necessary for this computation is reflected on the floorplanning cost function, the throughput increases by 16.97% on the average when compared with the floorplanning that uses the conventional heuristic throughput-evaluation-method.

In this paper we present the Low-Power Bus Driven Floorplan(BDF) in which the bus power consumption is minimized by using a new cost function. The previously reported BDF has used the cost function which minimizes only the chid and the bus area. However, such a cost function may not consider the bus power consumption determined by the topology of a bus in case of the segmented bus design. In this paper, we formulate a new cost function which. reflects the communication frequency and the real distance between blocks in a bus to model the bus power consumption. For the Low-Power BDF with the new cost function, the experimental results show the bus power consumption cost is reduced by 11.43% on the average.

최근 몇 년간 발생한 도시홍수 피해의 주요 원인은 배수관망의 통수능 부족 때문이다. 2010년과 2011년에 연이어 발생한 서울시 침수피해의 주된 원인도 통수능 부족이라는 것을 관련된 보고서 등에서 확인할 수 있다. 따라서 현재 진행중이거나 계획중인 주요 침수지구의 '하수관거 종합정비 사업'은 주로 합류식 우수관거의 통수능 확보를 위한 사업으로 진행되고 있다. 하지만 침수지역의 관거 통수능 확보를 위한 관경확대는 관거확대 공사비용, 공사에 따르는 교통정체, 주거지역 시민의 피해, 제한된 공사비 등 여러 측면에서 제한될 수 있다. 배수망의 평면계획은 배수망의 유출반응과 밀접한 관련이 있다. 따라서 이 경우 관경확대 이외의 다른 대안으로 합류식 우수관거의 평면계획을 새로이 검토할 수 있다. 본 연구에서는 여덟 방향 깁스모형을 개발하여 기존의 네 방향 깁스모형과 비교하여 배수관망을 더욱 정확히 표현하도록 하였으며, 개발된 깁스모형을 활용하여 신월지구의 배수망 특성을 분석하였다. 또한 깁스모형을 이용하여 분석한 신월지구의 최적 배수관망 평면계획을 SWMM 모델에 적용하여 기존 배수관망 시스템과 최적 배수관망 시스템의 효율성을 검토하고 도시유역 적용성을 검토하였다. 따라서 본 연구의 결과는 깁스모형의 도시 배수망에의 적용성을 높임과 동시에 배수망의 평면계획을 이용하여 유출량 저감을 도모할 수 있는 새로운 대안을 제시할 수 있을 것으로 기대된다.

The purpose of this study was to analyze and compare the characteristics of floor plan of Underwood hall, Appenzeller hall, and Stimson hall in Yonsei University. These buildings in Yonsei University are the representative higher educational institution buildings that were constructed by Western missionaries during the Japanese colonial period. These buildings were designed by the master plan that had been made before the construction. Therefore, these buildings have many similarities but each building has individual characteristics. This study focused on two parts. One is the characteristics of the shared space, such as like corridor, hall, and stairs. These characteristics show the differences between each building because they used different methods and locations of shared space and rooms for the floor plan to include the different functions. The second is the relationships with the floor plan and other plans like the master plan, elevation plan, and structural plan. These relationships show that each building has unique characteristics that are related to the floor plan.

This study presents a method to find the extant central halls with the plan most similar to the remains and to find out and compare the architectural style of extant buildings for the restoration. In the Joseon dynasty, there existed both remains and the extant hall. In particular, the $3{\times}2Kan$ hall is the minimum size that functions as the hall, so the number of comparison articles is small. The subjects are three remains and 29 Extant Halls. The absolute size of the comparison articles are the Area, Ratio of front/side, and the relative sizes are the Ratio of front Eokan/Hyeopkan and Ratio of the front Eokan/the side row. The Daeungjeon remain in Bugjijangsa is similar in absolute size and relative sizes to Oeosa daeungjeon. The Bubdang remain in Seonchalsaji is similar to Sangwonsa daeungjeon in the Area and Ratio of front/side, and similar to Daejeogsa geungnakjeon in the Ratio of front/side and Ratio of front Eokan/Hyeopkan. The Bubdang remain in Seungseonsaji is similar to Seodongsa daeungjeon in the Area, Ratio of front Eokan/Hyeopkan and Ratio of the front Eokan /the side row. Consequently, this method has high value as a way to expand by other comparison articles.

As a functionally complicated facility, it requires rational strategy to accommodate multi-functional needs to plan a hospital. Ambulatory surgery units located in large hospitals have problems such as longer waiting time and congestion for patients due to complicated planning and organization within limited area, which raise needs for independent ambulatory surgery centers to enable smoother medical treatment for patients. To design an independent ambulatory surgery center, understanding of zoning and layout of each unit needs is particularly required. This study focuses on research of efficient zoning/organization of day surgery unit and circulation arrangements of ambulatory surgery centers by analyzing various examples abroad, which will eventually help finding appropriate way of planning domestic ambulatory surgery centers. Specific area of research includes ambulatory surgery process, programmatic requirements, spatial organization of the facility, layout of surgery unit and circulation arrangements of ambulatory surgery centers.
