The Urban park plays a significant role as an ideal space for residents. In this sense, Seoul city established a criterion for urban park system according to the park size per person in each district of Seoul. However, that criterion tends not to meet the residents behavioral patterns and interaction dynamics between districts. The objective of this study is to establish the demand forecasting of urban park in Seoul. The result of this study shows that the priority of designating park area is changed greatly when interaction dynamics between districts is taken into account.

This study made a comparative analysis of the winning points in different sporting events of decathletes and positively identified how the preceding items experienced by them influenced competitive performance. The results are to be used as basic data for the selection of decathletes and improvement of their competitive performance. For the study, performance of 29 players who won 5500 points in total were sampled from athletic sports records from 1999 to 2002 published by the Korea Athletics Federation. After that, the following results were obtained through averaging, correlation analysis, multi-regression analysis and covariance analysis. 1) It was demonstrated that for Korean decathletes, competitive performance in Short put is relatively stronger compared with that of jumping and throwing, but that of throwing is relatively very low. 2) It was demonstrated that an individual item that has the greatest influence on performance was discus Throw and weight do not influence performance. 3) Items that have a significant difference of performance according to preceding athletic items performance were 110mH, long jump, pole vault and discus Throw. For 110mH, long jump, and pole vault, a good record was found when a preceding item was jump. For throwing, the best record was found in discus Throw.

The powder of ZrO₂-MgO systems prepared by co-precipitation method using ZrOCl₂· 8H₂O and MgCl₂· 6H₂O as the sintering materials. They are sintered and than heat treated to know that effects of agoing time and temperature on mechanical and electrical properties. The powder ZrO₂-MgO systems have∼30nm crystal size and tetragonal phase. The mechanical properties of these partially stabilized ZrO₂- MgO specimens are shown the best value when they are aged at 1,100℃ for 1 hr and at 1,450℃ for 10 hrs, but these are better than those, and while the specimens of 9.5 mole% in these thermal conditions. Electrical conductivities are measured as a function of temperature in the range of 500℃ to 1,000℃. The temperature dependence of electrical doncutivities is shown the activation energies by the heat reat conditions; no heat treating, heat treating at 1,100℃ for 1 hr, and heat treating at 1,450℃ for 10 hrs, and their values are 21.5㎉/㏖, 34.3㎉/㏖, and 43.5㎉/㏖, respectively.

Building integrated photovoltaic(BiPV)systems can from a cohesive design, construction, and energy solution for the built environment. The benefits of building integration are well documented and are gaining significant public recognition and government support. PV cells, however, convert only a small portion of the incoming isolation in to electricity. The rest is either reflected or lost in the form of sensible heat and light. In order to judge of the Integration capability to the BIPV system, energy efficiency, capacity and integration capability is studied by considering the production quantity of electric power and U-value of PV system.

고밀도 환경을 요하는 반도체 공장에서의 미진동 해석에 관한 연구

김동규,오재응 漢陽大學校 環境科學硏究所 1989 環境科學論文集 Vol.10 No.-

본 연구에서는 미진의 영향을 감소시키기 위하여 반도체 공장에서의 지반진동 특성을 파악하고 효과적인 진동저감 대책의 자료를 제시하였다. 측정결과에 의하면 고도의 청정도를 유지하기 위한 대형동력기 및 냉각탑이 옥상에 설치되어 있고 전기를 공급하는 전기실등 동력실이 지하실에 설치되어 있어 결국 상·하에 진동원이 존재하는 결과가 되고 있다. 또한 현재 가동중인 건물 정면 약 20m 위치에 공장전체에 동력 (Compressor 5. ) 을 공급하는 중앙공급실(동력원)이 위치하고 있어 주진동원이 된다고 생각되며 실제 새로운 공장이 위치할 부지에서는 중앙공급실에서 발생하는 20Hz 성분이 예정부지에도 나타나고 있음을 알 수 있다. In this study, to reduce the effect of micro-vibration seized the characteristics of ground vibration in semiconductor factory and presentated the effective counterplan. As a result of survey a large sized power equipment was situated on the roof and electrical equipment was located in the basement. So vibration source was located in top and bottom. Central power equipment that supplied the all over the factory was located infront of Main factory. So it looks main source and the components of 20Hz at central power equipment was also appeared at a plan site.

이주형,오제응 漢陽大學校 環境科學硏究所 1988 環境科學論文集 Vol.9 No.-

오늘날의 住居空間은 生活文化가 發達하고 變化함에 따라 經濟的이고 便利하여 졌으나, 騷音環境側面에서 불 때 적합하지 않은 문제점도 發生하게 되었다. 즉 騷音環境에 대한 要求가 더욱 세심해지고 住居空間의 構造變化에 따라 Wall Slab 아파트에서 structure-borne sound와 vibration이 심각한 문제로 제기되었다. 하지만 이에 대한 규제나 基準이 없는 실정이어서 生活文化發達에 부응하는 住居環境의 達成이 시급하다. 本 硏究에서는 Wall Slab구조 아파트에 대한 structure-borne sound와 vibration의 실상을 파악하기 위해서 "建築物의 現場에 있어서의 바닥 충격레벨의 測定方法"에 의해 소음과 진동을 측정하였다. 이에 대한 結論은 1) Wall Slab 와 R.C조를 비교한 결과 500㎐이하에서 약 10㏈의 차이를 보이면서 R.C조가 충격음과 진동에서 좋았다. 2) structure-borne sound와 vibration를 저감시키기 위해 Life Slab의 채택이 필요할 뿐만 아니라, 50~65m/m정도에 Life Slab는 가장 효율적인 節緣値를 나타냈다. The purpose of this study is to be calculated the problems of the Structure-bone sound and vibration to a apartment mode wall slab type and to be made the counterplan of noise reduction Actually based on respond to a resident, Structure-bone sound and vibration is measured with "Method for field measurement of floor impact sound level" The result of this study figures out: 1) The apartment mode reinforce concrete compared to the apartment made wall-siab has a good condition to a Structure-bone sound and vibration, taken the 10㏈ difference under the 500㎐. 2) Needed life-slab to apartment construction for the noise reduction of a apartment Structure-bone sound and vibration, having efficiently the 50~65m/m of life-slab increasing the degree of strength with a interior power wall within 5.Om of span in living space.

불명열 환자에서 진단된 중증 만성 활동성 Epstein-Barr virus 감염증

최근 장기적이고 심각한 임상 증상을 유발하는 만성 활동성 EBV 감염증의 개념이 정립되면서 그 증례들이 보고되고 있다. 만성 활동성 EBV 감염증은 소아나 젊은 성인들에게서 주로 발생되며, EBV-VCA IgG, EBV-EA IgG의 수치가 높게 관찰되고, 지속적인 발열, 전신쇠약감, 광범위한 임파선비대증, 간비장비대, 범혈구감소증, 다크론성감마병증을 나타낸다. 이 질환은 환자의 임상소견, 혈액학적 소견, EBV 항체 역가 및 침범 장기의 EBV genome 검출로 확진 되며 치료로 항 바이러스 체제, 항암 치료, 골수이식술 등이 시도되고 있으나 아직 검증되어 있지 않다. 저자들은 불명열을 주소로 내원하여 중증 만성 활동성 EBV 감염증으로 진단된 증례 4례를 경험하였다. 한 례에서는 항 바이러스 제제를 추여 후 임상적, 혈액학적 호전을 보였으나 치료 20일째 발생한 세균성 복막염과 패혈증으로 사망하였고, 두 례에서 총 6회의 CHOP 항암치료와 자가조혈모세포이식을 시행 받은 후 현재까지 증상 없이 추적관찰 중이다. 지속되는 발열을 주소로 내원한 불명열 환자들에게서 EBV에 대한 검사를 시행할 경우 불명열의 원인을 규명하는데 하나의 단서를 제공할 수 있을 것으로 사료된다. Epstein-Barr virus (EBV) is one of eight human herpesvirus. Primary infection with EBV in childhood is generally asymptomatic or mild, however, often causes overt diseases such as infectious mononucleosis (IM) and lymphoproliferative disorder (LPD), the latter occursing in immunologically compromised individuals. Historically, EBV has been considered to be etiologically linked to human malignancies such as EBV genome positive Burkitt's lymphoma and nasopharyngeal carcinoma. Recently, however, another category of EBV-related disease, "chronic active EBV infection", has been made to describe persons without a clearly defined underlying disease. We report 4 cases of patients, presented with episodic fever of unknown origin (FUO), who were diagnosed as severe chronic active EBV infection. A combined application of serology for EBV and in-situ hybridization established the diagnosis of the EBV infection.

PPV 공중합체의 합성 및 발광특성

민혜경,이경민,한동제,박성진,오응주 명지대학교 자연과학연구소 1997 자연과학논문집 Vol.16 No.-

Blue light emitting PPV [poly (p-phenylene vinylene)] copolymers soluble in common organic solvents are synthesized and their structural and light emitting properties are studied. Copolymers show π-π* transition in UV-Vis. spectra and their λmax shift to shorter wavelength compare to that of monomers. The PL and absorption spectrum shows the symmetric vibration modes with muror images which means that copolymers are highly, aligned. The band gap energy of these copolymers are ~3.0 eV. By introducing aliphatic hydrocarbon group into polymer main chain, the stability of copolymers is increased and no significant effects of substituents are observed.
