As urban waterfront is being actively developed all over the world, there is an active movement to develop waterfront of old port city in Korea. The purpose of this study is to investigate the development process of the waterfront in the redeveloped port city and to suggest the basic planning direction in waterfront dedign by analyzing plan characteristics of waterfront. As a research method, three kinds of accessibility, land use, and identity as planning characteristics of the waterfront were derived through analysis of previous research, and the case study of Marseille Port of Italy and Genoa Port of France were analyzed with this research analysis framework. The results are as follows. First, long-term urban development policy and master plan are essential for the activation of waterfront in port city. Second, to improve the accessibility of waterfront, some restrictions of vehicle access, a three-dimensional transportation system and various public transportation systems are needed for the pedestrian's access. Third, land use in the waterfront should be complex and diverse, these spaces must be interconnected, and public open space should be properly planned. Fourth, in order to make the identity of waterfront, it is necessary to maintain and manage historical buildings well, and create attractive waterfront through contemporary buildings with symbolic features such as public cultural facilities.

In the present study, a new angular discretization method, repulsive particle angular discretization (RPAD), is proposed for use with the three-dimensional radiative transfer equation (RTE). To discretize a solid angle as uniformly as possible, mutually repulsive particles on the unit sphere were introduced and directly used as radiation directions. To assess the uniformity of the radiation direction distributions of the RPAD and the other angular discretization methods, the minimum distances between control angles were compared. The assessment shows that the radiation direction distribution of the RPAD is the most uniform. The RPAD also achieved the most accurate first moment integral over the half solid angle. To assess various angular discretization methods including the RPAD in the three-dimensional spatial domain, they were adopted to solve two benchmark problems. The first benchmark problem is analysis of a cylindrical enclosure fill with a purely absorbing and emitting medium. In this problem, although the maximum radiative flux errors from the FTn FVM, IUSD, and RPAD were relatively similar, it was observed that the flux by the RPAD exhibits the least fluctuation for the varying surface direction with respect to the coordinate system. As a second benchmark problem, the rocket plume base heating was analyzed to assess the angular discretization methods in terms of pure scattering. It was observed that the maximum errors were smallest for the IUSD or RPAD, followed by the FTn FVM. However, the IUSD shows a relatively inaccurate radiative flux for a particular number of radiation directions. It was found that the RPAD proposed in the present study provides comparable or more accurate solutions for the three-dimensional RTE than the other angular discretization methods tested.

In the present information society, the office buildings should take a role of pleasant space to create, exchange and manage the knowledges and informations. However, qualitative evaluation on the architectural design of workspaces is not being done properly. That's why there's no enough evaluation tools to review the workspace planning level quantitatively and objectively. To design the appropriate workspace and pleasant working environment in the high-rise office buildings it needs to develop the quantitative planning indicators that enable to evaluate the design quality of workspace and to objectively compare and analyze the quality level of working environment. Statistic analysis on the results of satisfaction research on the workspace was finally made to get the planning indicators, through which 5 planning indicators were drawn as follows, centering around the finally extracted planning factors : Adjacent Ratio to Window, Workstation Area per Person, Conference Space Ratio, Resting Space Ratio, Vertical Partition Area per Person.
주민의 부정적 관광개발 영향 지각이 지역만족과 개발태도에 미치는 영향: 사회적 자본의 조절효과를 중심으로
정성문,강신겸 한국지역문화학회 2020 지역과 문화 Vol.7 No.1
본 연구는 관광목적지의 지속가능한 성장과 개발을 위한 관리의 수단으로 사회적 자본의 역할에 주목 하였다. 관광개발이 관광목적지에서 사는 주민들의 지역만족과 관광개발 태도에 미치는 영향 관계에서 사회적 자본이 지속가능한 관광개발을 견인하는 중요한 장치라는 점을 규명하는 데 궁극적인 목적이 있는 것이다. 이를 위해 과잉관광 현상이 나타나는 전라남도 여수시를 원도심과 비원도심으로 구분하여 관광개발의 부정적 영향에 대한 지각이 주민 지역만족과 관광개발 태도에 미치는 영향관계에 있어 사회적 자본의 조절효과를 검증하였다. 실증 결과 관광개발이 집중된 원도심이 상대적으로 개발에서 벗어난 비원도심보다 영향력을 발휘하는 것으로 분석되었다. 이는 사회적 자본이 관광개발의 부정적 영향을 줄이거나 또는 지속가능한 발전과 성장이 유지될 수 있도록 하는 관리의 수단이 될 수 있음을 보여주는 것이다. 이에 따라 민관협치 활성화 기본조례. 지역사회 동호회, 마을 총회 등과 같은 사회적 자본의 특성들이 반영된 다양한 정책들을 마련하여 활성화 시켜야 함을 제안하였다.

This study focuses on the building evaluation for the architectural planning of highrise office building through the analysis of workers satisfaction. In order to do this, we have made an investigation into the following elements. First, the selected buildings are investigated into the actual extraction of design considerations. Second, a prototype of workers satisfaction model is established to measure and determine the workers' satisfaction level of the selected buildings. And third, design improvement factors based on the analysis of workers satisfaction are established. The design considerations are extracted from the workers' satisfaction level with employing statistical analysis as well as developing systematic methods of the investigation.

In recent years, large-scale waterfront projects have been actively progressed in port cities such as Busan, Incheon, and Changwon, and many people have lots of attention to these. Therefore, the purpose of this study is to investigate how to plan programs for public cultural facilities in the development of waterfront in port cities, and what architectural characteristics will be given in terms of facility site planning and appearance. So, we analyzed the public cultural facilities of Inner Harbor in Baltimore, USA and Marina Bay waterfront area in Singapore. And then, five conclusions were drawn as follows. First, consistent master plan of long-term perspective in the development of waterfront of port city is essential. Second, in order to activate the public cultural facilities planned in the master plan, the connections between the facilities should be strengthened. Third, it is nessary to make a plan of public cultural facilities with diverse and original programs in the development of waterfront. Fourth, it is important that the waterfront public cultural facilities are actively connected with the waterside, and various open spaces are needed for this. Finally, it should have a unique form as a public cultural facility itself, and be harmonized with other surrounding environments.
Postreperfusion syndrome during liver transplantation
정성문 대한마취통증의학회 2015 Korean Journal of Anesthesiology Vol.68 No.6
As surgical and graft preservation techniques have improved and immunosuppressive drugs have advanced, liver transplantation (LT) is now considered the gold standard for treating patients with end-stage liver disease worldwide. However, despite the improved survival following LT, severe hemodynamic disturbances during LT remain a serious issue for the anesthesiologist. The greatest hemodynamic disturbance is postreperfusion syndrome (PRS), which occurs at reperfusion of the donated liver after unclamping of the portal vein. PRS is characterized by marked decreases in mean arterial pressure and systemic vascular resistance, and moderate increases in pulmonary arterial pressure and central venous pressure. The underlying pathophysiological mechanisms of PRS are complex. Moreover, risk factors associated with PRS are not fully understood. Rapid and appropriate treatment with vasopressors, volume replacement, or venesection must be provided depending on the cause of the hemodynamic disturbance when hemodynamic instability becomes profound after reperfusion. The negative effects of PRS on postoperative early morbidity and mortality are clear, but the effect of PRS on postoperative long-term mortality remains a matter of debate.
