Korea has achieved a rapid economic development and with the increase in population and national income and the expansion of social andeconomic activities, energy consumption has rapidly increased too. Energy consumption per head has constantly increased and currently, powerconsumption per head is 7.5 times bigger than in 1985. Buildings occupy 25% of total energy consumption and especially, 50% of totalenergy is consumed for heating and cooling. In this situation, multi-family housing, which has constantly been increased, has an energysaving rate of 1.9%, which is the lowest level and this makes the government’s energy policy for sustainable energy system developmentuseless. Besides, energy consumption leads to secondary problems, such as air, water and marine pollution and heat pollution andwastewater/drainage and the increased use of fossil fuel is a fundamental reason for ozone layer destruction and global warming. Therefore,efficient energy consumption plans are required. This study aims to analyze energy performance in each block type of high-rise anddiversified multi-family housing that accounts for 60% of all the housing forms, depending on the variations in stories through BIM-basedenergy simulation. For this study, four representative block types were selected, based on the multi-family floor plan, which is certified forenergy performance evaluation and they were applied to the floor plan of a multi-family house that is scheduled to be built. Then BIMmodeling was conducted from the fifth story to the 40th story at an intervals of 5 stories and based on the finding, energy characteristics ofeach block type and energy performance depending on the variations in stories were analyzed. It is considered that this would serve asobjective data for block type and block story decision of energy performance-based multi-family housing. 본 논문에서는 전체주택의 60%를 차지하고 있으며 점점 더 고층화, 다양화 되어가는 공동주택의 주동형태별 에너지 성능 및 층수 변화에 따른 에너지 성능을 BIM 기반의 에너지 시뮬레이션을 통하여 분석하고자 하였다. 에너지성능평가의 본 인증을 취득한 공동주택 평면도를 기초로 선정된 4가지 대표 주동형태를 실제 준공 예정인 공동주택의 평면도에 대입하여 5층 단위로, 5층에서 40층까지 BIM 모델링을 실시하고 그 결과 값을 통하여 주동형태별 에너지 특성과 층수변화에 대한 에너지 성능 변화를 분석하였다.

Since the smart device hardware related technology has been rapidly developed and it can provide fast processing speed recently, the interest of real-time representation for 3D deformable objects has been focused in various fields of developing applications for smart device. To present the method for implementation of robust and fast dynamic simulations based on iPhone 5, this paper analysis the possible representation number of deformable objects and complexity of objects which can be computed in real-time by test of various 3D deformable objects. The implemented physically-based FFD-AABB algorithm utilized the 2-level bounding sphere based approach provides fast collision detection and handling using the shape analysis of 3D deformable objects. In addition, to evaluate the performance of implemented algorithm we perform the free falling simulation test from the predefined height with various shapes of 3D deformable objects. Therefore, this paper presents the 2-level bounding sphere based modeling of objects using the shape analysis for fast collision detection and provides the guideline of 3D deformable object modeling for real-time simulation with iPhone 5.

Due to the development of various types of applications, the activated smartphone market has been rapidly expanded these days. Increasingly game market uses smart devices rather than PC environment because customers use smartphones anytime and anywhere they want. Smartphone users want games which have more sense of reality so than recent released games include physics engines in their applications. However smartphones in market cannot sufficiently provide computing speed which is required by physics engine. This paper implemented and provided the possibility of applications for various types of 3D deformable object simulation with physics engine in IOS based smartphones. Also this paper analysed the possibility of inclusion of physics engine for collision detection and handling of 3D deformable objects in smartphone.

반도체 산업의 wafer 가공공정에서 발생하는 폐수를 재활용하고자 한외여과 공정을 이용한 막분리 공정의 도입 가능성을 검토하였다. Pilot 규모의 장치에 분획분자량이 각각 10,000, 20.000, 30,000인 한외여과막 모듈을 이용하여 투과유속 및 제거율 등을 측정하였다. 투과수의 성상은 SDI15, 탁도, 전기전도도, 실리콘 농도분석을 통해 공정수로 재이용이 가능함을 확인할 수 있었다. 투과유속 저하를 막기 위한 역세척 방법으로는 압축공기와 물은 sweeping 하는 방법이 가장 효과적이었고, 이때 투과유속의 회복율이 높게 나타났다. 분획분자량 30,000인 한외여과막에서 가장 높은 투과유속을 나타내었다. 또한 폐수의 평균 실리콘 입자 평균 함량은 3.8-5.6mg/ℓ이고, 투과수의 실리콘 입자 함량은 0.2μg/ℓ이하로 나타나 제거율은약 96%이상으로 나타났다. The ultrafiltration characteristics of wafer processing wastewater produced from semicon-ductor industry was investigated for wastewater reuse. Using the pilot-scale ultrafiltration system containing poly sulfone hollow fiber membranes (MWCO : 10,000, 20,000, 30,(00), the membrane performance, such as flux, rejection rate and concentration factor for flux was examined. The SDhs, turbidity, electrical conductivity and concentration of Si particles were measured, and the possibility of permeate reuse was validated from the experimental results. It was shown that the flux was recovered by the sweeping with air and water effectively. The permeate flux of 30,000 MWCO membrane was about 5 times higher than that of 10,000 and 20,000 MWCO membranes. The concentration of Si particle in the saw wastewater was analyzed 3.8-5.6 mg/ℓ and that of Si particle in the permeate was analyzed less than 0.2μg/ℓ. This means the rejection of silicon particle was over 96%.

외상유도성 국소성 피부 경피증 3예

전재홍,이창우 ( Jae Hong Jun,Chang Woo Lee ) 대한피부과학회 1997 대한피부과학회지 Vol.35 No.6

We describe three cases of morphea which present lesions of the disease at the site of mechanical traumas. In these patients, local traumatization of cutaneous tissue appear to be the initiating event for the developrnent of new lesions (isomorphic phenomenon) associated with their possible morphea prone constitutions. The mechanism involving these local stimuli responsible for the excessive collagen production is lifficult to explain. Upon biologic stress or trauma, normal cutaneous physiology may cause loca production and release of inflammatory mediators/cytokines, such as transforrning growth factor-gthe major connective tissue growth factor-inducer). Perhaps, possible dysregulation of collagen-growth or fibrosis- promoting cytokines causing some clonal overactivity of the fibroblast, or with other undefined mechanisms may cause excessive synthesis of collagen to the local effects of such triggering factors in susceptible/subclinical individuals. Although no definite environrriental/physical influences on t,he developrnent of morphea have been described, rnechanical trauma niay occasionally be regarded as a contributing factor as seen in these patients.
