한국성에 나타난 바이오필릭 디자인 표현특성 연구 - 창덕궁 연경당과 소쇄원을 중심으로 -

바이오필리아와 디자인의 결합어인 바이오필릭 디자인(Biophilic Design)은 인간과 자연의 연결성과 상호작용이 인간에게 안정감과 평온함을 주고, 최적의 편안함을 제공하기 때문에 자연이 도입된 디자인 공간을 선호한다는 것에 기반한다. 바이오필릭 디자인에 대한 개념과 연구는 1986년 미국을 시작으로 2000년대부터 활발히 연구되었으며 국내에는 2010년 전 후로 도입되어 치유공간, 교육공간, 그리고 업무공간과 관련한 연구가 활발히 진행되고 있다. 한편, 생명 사랑에 바탕을 두고 있는 바이오필릭 디자인의 개념은 한국 옛 선조들의 자연과의 조화를 중시하고 생명 존중이 건강과 풍요를 이끈다는 사상과 많은 일치점을 가지고 있다. 연구의 목적은 바이오필릭 디자인의 표현특성을 이해하고, 한국성에 나타난 바이오필릭 디자인 표현 특성을 구별하여 조사하는데 있다. 연구의 방법은 사례조사를 채택하였다. 한국 전통성이 잘 구현되어 있는 전통 공간을 사례로 선정하였으며 스티븐 켈러트(Stephen Kellert)의 바이오필릭 디자인 표현 특성을 도구로 사용하여 분석하였다. 분석한 결과와 서양에서 유입된 바이오필릭 디자인 표현 특성을 비교하여 한국성에 나타난 바이오필릭 디자인의 표현 특성을 도출하였다. Biophilic Design, the word that combines biophilia and design, is based on preferring a design space in which nature is introduced, because the connection and interaction between humans and nature give humans a sense of stability and tranquility and optimal comfort. The biophilic design have been actively studied since the 2000s after using the ‘Biophilia’ in 1986 by Edward O. Wilson. Then it was introduced at 2010’s in Korea, and the studies related to healing and work spaces were actively being conducted. On the other hand, the concept of biophilic design has many consensus with the idea that harmony with nature and respect for life of the Korean ancestors that leads to health and abundance. The purpose of this study is to find out the characteristics of biophilic design in traditional Korean spaces as the unique expression characteristics, and present them as design elements of modern Korean design as a biophilic design. A case study was selected for research methodology. Korean traditional spaces that expresses Korean identity were selected as an example, and then the characteristics of the biophilic design by Stephen Kellert were used as a analysis tool. The results were the characteristics of biophilic design that appeared in Korean design.

Three formula types (gel, cookie, and liquid), six commercial roach bait products containing one of active ingredients among Fipronil, Avermectin, Dinotefuran, and Chlorpyrifos were examined against susceptible strain of German cockroach, Blattella germanica (L.). For the results of killing speed (LT50 values), universal killing speed effects depended on bait formula types. The killing speed of liquid bait formula type was the fastest among three formula types. Followed by gel bait type and cookie bait type. However the control speed (LT90 values) effects depended on the active ingredients that contained in roach baits. The baits contained Fipronil were shown the strongest control performance against German cockroaches. Chlorpyrifos was similar with Fipronil. Followed by Avermectin and Dinotefuran.
Dissolution Behavior and Hydrate Effect on CO₂Ocean Sequestration
Namjin Kim,Chongbo Kim 대한기계학회 2005 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.19 No.5
CO₂ocean sequestration is one of the promising options to reduce CO₂ concentration in the atmosphere because the ocean has vast capacity for CO₂ absorption. Therefore. in the present investigation. calculations for solubility and dissolution behavior of liquid CO₂ droplets released at 1000 m and 1500 m deep in the ocean from a moving ship and a fixed pipeline have been carried out in order 10 estimate the CO₂ dissolution characteristics in the ocean. The results show liquid CO₂ becomes CO₂ bubble at around 500 m in depth. and the solubility of seawater is about 5% less than of pure water. Also. it is shown that the injection of liquid CO₂ from a moving ship is a more effective method for dissolution than from a fixed pipeline. and the presence of hydrate on liquid CO₂ acts as a resistant layer in dissolving liquid CO₂.
Combined Convection and Radiation in a Tube with Circumferential Fins and Circular Disks
Namjin Kim,Jaeyong Lee,Taebeom Seo,Chongbo Kim 대한기계학회 2002 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.16 No.12
Combined convection and radiation heat transfer in a circular tube with circumferential fins and circular disks is investigated for various operating conditions. Using a finite volume technique for steady laminar flow, the governing equations are solved in order to study the flow and temperature fields. The P-1 approximation and the weighted sum of gray gases model (WSGGM) are used for solving the radiation transport equation. The results show that the total Nusselt number of combined convection and radiation is higher than that of pure convection. If the temperatures of the combustion gas and the wall in a tube are high, radiation becomes dominant. Therefore, it is necessary to evaluate the effect of radiation on the total heat transfer.

We propose an algorithm for the optimal operation schedule of the BOG compression process based on simulation of the dynamic behavior of an LNG tank. The algorithm uses an empirical boil-off rate model to predict the amount of BOG generation, and an MILP formulation to distribute the BOG compressors loads. Finally, a safety analysis is done using a dynamic simulator. To improve the accuracy, Aspen Dynamics with the Peng-Robinson equation of state is used in place of a simplified dynamic model used before. The dynamic simulation of the LNG tank pressure showed the results of oscillation within a safe pressure range while the BOG compressors were operated normally. The performance of the proposed algorithm was found to be superior to the algorithm used in routine processes as well as those from previous works in terms of safety and energy savings.
