Objective : This experiment was conducted to evaluate the effectiveness of Acupuncture, Bee Venom Acupuncture (BVA) and Bee Venom Herbal Acupuncture (BVHA) on post-stroke hemiplegic shoulder pain. Methods : 30 patients were randomly allocated into Acupuncture group, BVA group and BVHA group and was monitored weekly for 4 weeks; initial($T_0$), 1 week($T_1$), 2 weeks($T_2$), 3 weeks($T_3$) and 4 weeks($T_4$). Results : Visual analogue scale of shoulder pain showed significant decrease in BVA and BVHA groups compared to the Acupuncture group at T4 evaluation. Painless passive ROM of shoulder external rotation and Fugl-Meyer Motor Assessment of Upper Limb motor function showed significant increase in all groups. Modified Ashworth scale of the spasticity of upper limb showed no differences between the three groups. Conclusion : BVA & BVHA appears to be an effective in treating post-stroke hemiplegic shoulder pain. Further clinical studies must be done to obtain more concrete findings.

Lately, there has been active establishment of standards relevant to effective solar heat protection including the installation of external shading devices and others of the kind in order to reduce summertime cooling energy use in office buildings. The objective of this study lies in analyzing the SHGC of overhang and side-fins considering solar geometry with the use of a representative program originated from ISO 15099 called EnergyPlus and extracting a new calculation method considering the correlation. For achievement, a simulation model was set and calculations for SHGC value of each direction was conducted focusing on glass and shading devices. Analysis on extruded length for each solar altitude was conducted for overhang and analysis on extruded length for each solar azimuth was conducted for side-fins. When defining SHGC of external shading device by disregarding previous complicated formulas and introducing the concept of sky opening ratio, the influence of both direct and diffused solar radiation can be considered. In case of overhang, a new correlation formula with deviations of less than 1 % was extracted by introducing the blockage ratio concept of shading devices or sky opening ratio concept of windows. Also, in case of side-fins, it presented very similar SHGC values for all directions and a new correlation formula with deviations of less than 5%, was extracted for all directions with the use of the sky opening ratio.

When it comes to these buildings for business use, cooling load during summertime was reported to have great importance which, as a result, impressively increased interest in Solar Heat Gain Coefficient (SHGC) is considered to be lowered with the help of colors and functions of glass itself, internal shading devices, insulation films and others but basically, these external shading devices for initial blocking that would not allow solar to heat to come in from outside the buildings are determined to be most effective. Of many different external shading devices, this thesis conducted an analysis on Exterior Venetian Blind. As for vertical shading devices, previous researches already calculated SHGC conveniently using concepts of sky-opening ratios. However in terms of the Venetian Blind, such correlation is not possibly applied. In light of that, in order to extract a valid correlation, this study first introduced a concept called shape factor, which would use the breadth and a space of a shade, before carrying out the analysis. As a consequence, the concept helped this study to find a very similar correlation. Results of the analysis are summarized as follows. ① Regarding SHGC depending on the surface reflectance of a shade, an average of 2% error is observed and yet, the figure can always be ignored when it comes to a simple calculation. ② As for SHGC of each bearing, this study noticed deviations of 4% or less and in the end, it is confirmed that extraction can be achieved with no more than one correlation formula. ③ When only the shape factor and nothing else is used for finding a correlation formula, the formula with a deviation of approximately 5% or less is what one would expect. ④ Since the study observed slight differences in bearing depending on ranges of the shape factors, it needed to extract a weighted value of each bearing, and learned that the smaller the shape factor, the wider the range of a weighted value. The study now suggests that a follow-up research to extract a simple calculation formula by dealing with all these various inclined angles of shade, solar radiation conditions of each region (the ratio of diffuse radiation to direct radiation and others) as well as seasonal features should be carried out.

음식물류폐기물의 친환경적 처리를 위해 퇴비화 및 사료화 등 재활용 기술의 연구가 활발히 진행되고 있다. 음식물류폐기물 혼합퇴비(이하 음폐혼합퇴비)는 수확량 및 품질 면에서 긍정적인 측면이 있다는 연구결과도 보고되었다. 많은 연구 결과에서는 작물생육의 지표로서 품질, 생장량, 수확량 등으로 사용하였으나, 작물이 사용가능한 토양 중 수용성 이온의 농도와 작물체로 흡수된 수용성 이온의 농도에 관련된 연구는 미비하였다. 이에 본 연구에서는 토양 및 작물체 추출액의 수용성 Cl<sup>-</sup>, SO<sub>4</sub><sup>2-</sup>의 농도를 모니터링하여 음폐혼합퇴비의 처리가 토양 및 작물체에 미치는 영향을 확인하였다. 처리구는 무처리구, 무기질비료 반량, 정량 처리구(질소표준시비량 기준), 무기질비료 반량에 음폐혼합퇴비 정량, 2배, 3배(질소표준시비량 기준)를 첨가한 처리구로 총 6개 이며 3 반복, 난괴법을 적용하였다. 토양은 1:5 증류수 추출하였고, 작물체는 homogenized 1:20 증류수 분쇄 추출하였다. 재배 중 토양 추출액의 EC와 Cl<sup>-</sup>, SO<sub>4</sub><sup>2-</sup>의 농도는 높은 상관관계(r<sup>2</sup>〉0.7)를 보였으며, 전 기간 동안 유사한 경향이 있었다. 재배 중 작물체 추출액의 EC와 Cl<sup>-</sup>의 농도는 전 기간 동안 다소 약한 상관관계(r<sup>2</sup>〉0.5)를 보였고, 토양과 비교하여 낮은 상관관계를 나타내었다. 재배 중 작물체 추출액의 EC와 SO<sub>4</sub><sup>2-</sup>의 농도는 생육 초기에 낮은 상관관계(r<sup>2</sup>〈 0.3)를 보였으나, 생육 중반 이후 상관관계(r<sup>2</sup>〉0.4)가 다소 증가하는 경향이 보였다. 재배 중 토양과 작물체 추출액 간 Cl<sup>-</sup>, SO<sub>4</sub><sup>2-</sup> 농도는 약한 상관관계를 나타내었다. 작물체 추출액의 농도는 토양추출액의 농도와 관계없이 각 시기별 일정한 농도 수준을 보였고, 생육 중반 이후 다소 감소하는 경향을 나타내었다. 공시 토양은 시설재배지로 높은 염 농도와 공간적 변이성에 의해 음폐혼합퇴비 처리시 토양의 EC는 증가하지 않은 것으로 보여진다. 토양 Cl<sup>-</sup>, SO<sub>4</sub><sup>2-</sup>의 농도는 생육기간 동안 크게 변하지 않았고, 작물체 Cl<sup>-</sup>, SO<sub>4</sub><sup>2-</sup>의 농도는 생육 중반 이후 다소 감소하였다. 이는 작물 생체량이 증가할 때, 뿌리 흡수 능력이 비례하여 증가하지 않아 작물체의 농도가 다소 감소하였을 것으로 생각되었다.

The main purpose of this paper is to develop the new BIPV module equipped with vacuum glass. Beacuse BIPV module has a function of architectural materials, thermal and PV performance should be simultaneously evaluated. To improve the thermal performance of BIPV module, this study developed BIPV module equipped with a vacuum glass. Those BIPV module was tested with a variety of encapsulants. The results are as follows. When a vacuum glass is laminated with EVA or PVB, it was broken. The reason seems to be bending by unbalance of heat expansion with center and edge of vacuum glass. In case of lamination with resin, there is no breakage and no bending of vacuum glass. Because production was conducted in low pressure & low temperature conditions. And it was also found that vacuum glass does not interfere with the UV curing process.

The purpose of this study is to deduct BIPV system installation current status and characteristics of BIPV module size and output through case analysis of building integrated photovoltaic systems applied in public buildings by new & renewable energy installation obligation system from 2007 to 2012 and present BIPV system supply performance improvement plan. Analysis by year, capacity, subject organization, facility categorization of BIPV system and size, output by unit area of BIPV module was analyzed. The analyzed results are as follows. (1) BIPV system was installed in 71 locations of 2.7MW from 2007 to 2012 and frequency by BIPV system installation capacity range was highest in 10kW∼20kW with 31%. Also, it was most applied in public work facilities with 33.8% and next was education·society educational institutes with 26.8%. (2) BIPV module was most installed in building facades instead of curtain walls in which form was G-to-G double-glaing type and G-to-T type with proportion of 38% each. (3) BIPV module size was all under 2㎡ and most size was 1.0∼1.5㎡. This size is scarce to replace building material with BIPV module. Therefore, research development on large-scale BIPV module is required. (4) BIPV module output by unit area was most frequent in 100∼125W/㎡. Based on these results, it is thought that 9∼10㎡ installation area is required to install 1 kW BIPV system. Also, high-efficiency of BIPV module is required to install BIPV system of more capacity in limited area.
