Even though efficiency of coal-fired power plant is proportional to operating temperature, increasement of operating temperature is limited by a technological level of each power plant component. It is an alternative plan to increase operating pressure up to ultra super critical point for efficiency enhancement. It is difficult to control process of power plant in ultra super critical point because that point has highly nonlinear characteristics. In this paper, new control logic, Unit Response Optimizer Controller(URO Controller) which is based on Fuzzy logic and Model Predictive Controller, is introduced for better performance. Then its performance is tested and analyzed with design guideline.

Recently the hospital infection with misappropriation of the antibiotic and absence of knowledge is aincreaseing trend. For this, medical treatment is confronting infection management guide. But so far there is no accurate standard or countermeasures. Since early 1990 Nosocomial Infection has not been looked over, although there is serious problem. After 90's understanding seriousness of Nosocomial Infection, many investigations have been done, but the relations of medical facilities were hardly investigated. This thesis shows the relation between facilities and Nosocomial Infection by documental references and the direction for intensive care unit through survey the recent general hospitals.

The block-unit housing renewal project was presented as an alternative method to overcome the side effects of large-scale renewal projects while improving poor residential conditions. However, projects implementation is prolonged and even the pace of projects, which was considered an various incentives, is being delayed for the most part. In this study, delay factors are drawn by eight; conflict among association members, contract delay of joint implementation, participation paucity of constructor, inadequate project guidelines, alteration of project plan, lack of renewal project professionals, stricter loan restriction of HUG, lack of capacity of project operator. We categorized those eight factors to three aspects such as implementation, participants and proposition and suggested improvement alternatives according to three aspects.

A construction site survey is carried out for the Construction Standard Unit Price(CSUP) in order to establish a standard for the appropriate estimated price. This paper proposed the revised plan by surveying the 56 sites under construction from March to October 2022 for interior finishing work and Carpentry work. It is expected that the revision of the CSUP for interior finishing work and Carpentry work will more accurately reflect the actual construction situation and contribute to improving the adequacy of the CSUP.

The major goal of this study is drawing design plan factors considering residents' life cycle and life style when remodeling design is needed. By drawing such design factors, the study will propose an alternative remodeling design plan. Such design method was defined as Multi-Dimensional module design method. And constructing data-system based on Multi-Dimensional module was secondary goal in this study. The details are as follows: Based on analysis of Residents' demand for remodeling and features of emotion-design applied to remodeling, the system which is suitable for application in remodeling design method was conducted. Based on the type of construction materials, the level value was set up according to emotion-factor application. Also, by conducting coding operation according to the distinction of construction materials, this study seeks the unit drawing method of information for constructing emotion-information system.

The objective of this study is to find a possible application of small space utilization of GangSo Housing, so called compact-but-effective housing, through analyzing that of Japanese small housing. We analyze openness of view and flexibility of spaces divided by the physical and architectural aspects as first component and the psychological and interior space aspects as second component. The results showed that Japanese small houses have various unit plan compared to uniformity of Korean houses. Openness of view in Japanese small housing is accomplished by letting in light from the outside using position and shape of the window, looking more spacious using courtyard, void spaces, or sliding door hanging from the ceiling, and creating deception of view using floor-wall plan and appropriate materials. Flexibility of spaces is achieved by combination of first and second components, multipurpose of space and furniture, and variety of storage methods. It is necessary to improve spatial efficiency with consideration of volume-metric planing rather than flat-plane and develop various unit plans to meet residents' needs and demands on compact-but-effective houses.

In the event of a disaster, we need people who specialize in rapid regional disaster recovery. However, in the present disaster response system, disaster relief is carried out at the level of public support, volunteer service, etc. There are various problems such as initial response due to lack of expertise, delays in disaster recovery, and inadequate response to disasters. Therefore, it is necessary to establish a unit with early ability to respond to local governments in the event of a disaster and expertise to enable rapid disaster recovery. Therefore, this study limited the preparation of the reserve forces emergency response units for the direction of local security, disaster relief and disaster relief through emergency disaster recovery under the disaster situation.

Korea has designated 28 trade ports and 22 coastal ports under the Ports Act. If fishery ports and small inlets are counted, the number amounts to hundreds of ports. However, untimely and inefficient maintenance and repair works face Korean ports with functional loss, decreasing efficiency, and even catastrophe. Thus, further examinations on the maintenance or redevelopment of forts in Korea are urgent. Since the Korean War and the higher economic growth period in the 1970s, Busan Port has developed in a variety of ways, according to the necessity of social conditions at any given time, without any development Philosophy or systematic long-term master plan. As a result, ports and coastal industrial facilities have rushed to gather around the present North Busan Port, which has taken on mixed functions between ports and cities, adversely affecting several of their interactions. To resolve these circumstances, several redevelopment schemes were suggested for centering the old zone in the Busan Port interim. However, comprehensive evaluation and redevelopment schemes combining functions of both ports and cities, and effectively utilizing coastal zones have never been presented. In this respect, this study sets the priority order of the extracted unit project. This study analyzes the existing functions and facilities of Busan Port, extracting facility zones through redevelopment which is certain to fail or to decrease in efficiency. furthermore, this study presents status and development directions of specified redevelopment unit projects of higher priority order, and pursues the integrated plan of efficiency for Busan Port.

Although Changdong Sanggye area has been developed during 1980s as a new city for the supply of low-income housing, currently it was degraded to a bed town located outside Seoul. However, Changdong Sanggye area is designated as the center of a metropolitan area in '2030 Seoul City Basic Plan' due to a variety of potential factors such as a traffic center for linking metropolitan areas, location of 15 universities, and neighboring natural environment like Jungnang stream and Buckhan mountain. The purpose of urban regeneration plan is to create a new CBD of Changdong Sanggye which is the center of vocational and cultural lives of 3.2 million people in the northeastern metropolitan area. To achieve the purpose, 12 unit projects and 24 sub-unit projects are set up based on the three major goals and core strategies. An enterprise project team of northeastern area was newly founded and then a dedicated organization was established by the Seoul government in 2015 in order to integrate separated urban regeneration related functions. In the Seoul government an administrative council and a project promotion council are operated for consultation and coordination between the administrative divisions and government projects for urban regeneration. Through the success in Changdong Sanggye regeneration project, they are expected to have economic effects such as job creation and increase in tax revenue and to re-vitalize the area as a new economic center in northeastern Seoul having amenities and cultural facilities and waterfront parks.
