Objectives : I would find out the exact interpretation and meaning of 'Yin sheng ze Yang bing Yang sheng ze Yin bing' in "Su Wen(素問) Yin Yang Yin Xiang Da Lun(陰陽應象大論)". Methods : I had searched the opinions of annotators about this paragraph and compared treatment principles that clinicians, such as Son Samak(孫思邈), Lee Cheon developed. Results : This paragraph is related to theory of the paragraph 'chong han ze re(重寒則熱), chong re ze han(重熱則寒)'. Yin and Yang in Yin sheng and Yang sheng mean the chill and heat of herb, food or symptoms, Yin and Yang in Yang bing and Yin bing mean outer and inner portion in body. Conclusions : The meaning of this paragraph moved from the aspect of recuperation to the aspect of disease-related change.

Most of solar system dissemination has been focused on domestic hot water system of which utilization to a building is relatively simple and safe than solar heating system. Through the survey on a cause of solar house dissemination failure in Korea, we conclude that design integration and systematic approach method for technology application are the most important element for a successful solar house. KIER(Korea Institute of Energy Research) and Hanbat National University have started new project on a development of Zero energy Solar House, called ZeSH which can be sustained just by natural energy without the support of existing fossil fuel. This is the 1st phase research of 10 years long-term ZeSH plan which develops a low-cost and $100\%$ self sufficient ZeSH. The goal of 1st phase ZeSH research is to get a $70\%$ self sufficiency only in thermal loads. Actual demonstration house, named KIER ZeSH I was designed and constructed as a result of 1st phase research work in the end of 2002. Various innovative technologies such as super insulation, high performance window, passive and active solar systems, ventilation heat recovery system are applied and evaluated to the KIER ZeSH I. A lot of computer simulations had been conducted for the optimal design and system integration in every design steps. Considering all the results from detailed hourly computer simulation, it is expected that at least $70\%$ self-sufficiency in thermal loads which is 1st phase target value can be excessively achieved in actual demonstration house. Besides, many valuable findings from the design and analysis to construction could be established such as collaboration method among the participants, practical design and construction techniques for system integration and the others. The purpose of this paper is to introduce the main findings through the development of KIER ZeSH I project. Practical guidelines in every design step for new low- or zero- energy solar house is proposed as result.

Objective : This study was designed to investigate anti-oxidative, anti-aging and anti-inflammatory activities of Zingiber officinale Roscoe water (ZD) and 50% ethanol extracts (ZE). Method : The antioxidant capacity of ZD or ZE was analyzed by DPPH, ABTS scavenging activities and reducing power, respectively. The anti-aging efficacy was performed with tyrosinase and collagenase inhibition activities. The anti-inflammatory activities were confirmed through inhibition of nitric oxide production and TNF-�� expression in LPS-treated Raw 264.7 cells. Result : As a result of measuring DPPH and ABTS radical scavenging activities, both ZD and ZE extracts increased in concentration-dependent manners. The ABTS radical scavenging activities of water and 50% ethanol extract were similar to that of positive control at high concentration. On reducing power, both ZD and ZE showed higher activities than the positive control at high concentration. On inhibition activities of tyrosinase and collagenase both ZD and ZE showed the large inhibition rates at low concentration. Also, the inhibitory efficacy of ZD on NO and TNF-�� production was better than ZE in RAW 264.7 cells. Conclusion : These results suggest that ZD and ZE have anti-oxidative, anti-aging and anti-inflammatory effects in vitro. Especially, ZD was more effective than ZE. Thus, Ginger extract is considered to be highly useful as a cosmetic or food material with anti-oxidative, anti-aging (prevention of whitening and wrinkle) and anti-inflammatory effects. Also these effects may vary depending on the extraction solvent.

최근 효소 기반 탄산칼슘 침전(EICP) 기법은 시멘트 기반 지반보강공법의 대안 중 하나로 간주되어 왔다. 하지만 EICP 기법에서 발생하는 환경 유해 부산물인 암모늄 이온의 배출에 대한 문제는 해결되지 않고 있다. 따라서 본 연구에서는 칼슘 치환 제올라이트를 사용하여 환경 유해 부산물이 없는 EICP(Ze-EICP)의 실험적 연구를 수행하고자 한다. 실험결과는 칼슘 치환 제올라이트를 사용하는 Ze-EICP가 염화칼슘을 사용하는 EICP와 비교하여 암모늄 이온은 96.96%가 제거되었으며, 거의 동일한 양의 탄산칼슘이 침전되었음을 보여주었다. 또한 Ze-EICP는 제올라이트의 조밀화와 탄산칼슘의 고결화로 인해 EICP 대비 높은 강도증진 효과를 보여주었다.

The purpose of this study is on the thermal performance evaluation of KIER Zero Energy Solar House-II, called ZeSH-II which can be sustained with the support of a very few energy. This ZeSH-II was designed and constructed in the end of 2009 to develop for the goal of 70% self-sufficiency. Several key technologies like as the super insulation, high performance window, wast heat recovery system as well as solar power and thermal system and geo-source heat pump wear used for this ZeSH-II. The monitering of ZeSH-II was conducted for six months from November 2009 to April 2010. The monthly energy consumption was calculated based on the monitering results. As a result, the ZeSH-II shows that the energy self-sufficiency during six months(from oct. to apr.) is about 80% which is higher than that of the target.

HFO refrigerants have recently come to be regarded as promising alternatives to R134a for use in turbo chillers. This study provides results from experiments evaluating the film condensation heat transfer characteristics of HFO refrigerants R1234ze(E) and R1233zd(E) on smooth horizontal laboratory tubes. The experiments were conducted at a saturation vapor temperature of $38.0^{\circ}C$ with surface sub-cooling temperatures in the range of $3{\sim}15^{\circ}C$. We observe that the film condensation heat transfer coefficient decreases as surface sub-cooling temperatures increase. In the case of laboratory tubes with a diameter of 19.05 mm, the film condensation heat transfer coefficients of R1234ze(E) and R1233zd(E) were approximately 11% and 20% lower than those of R134a, respectively. Furthermore, our investigation of the effect of tube diameter on film condensation heat transfer coefficients, demonstrates an inverse relationship where the film condensation heat transfer coefficient increases as laboratory tube diameter decreases. We propose experimental correlations of Nusselt number for R1234ze(E) and R1233zd(E), which yield a ${\pm}20%$ error band.
