김근우 대한한방신경정신과학회 2004 동의신경정신과학회지 Vol.15 No.2
Objects : This study was aimed to investigate relation to the Psychologic factor and Mental disorder of Women. Methods : Research data is based on Booindaejoenyangbang(婦人大全良方) and Dongyipogam(東醫寶鑑). And study the psycho elements in Mental disorder of Women. Results : 1. Psychologic factor have a part in A cause for mental disorder of women, certainly. 2. The weakness is fundamental cause for mental disorder of women and the Wind is an immediate cause frequently. 3. Most mental disorder of women develop severe psychiatric symptoms. 4. Psychologic factor is concerned to causing and symptoms at various diseases of women. Conclusion : The results suggest that women is delicate at the psychologic factor, so mental disorders are taken easily.

The (La0.7Ca0.3MnO3)1x/(NiFe2O4)x (x = 0 to 0.09) composites were prepared using a conventional solid state reaction method. The structural, magnetic properties, and electrical properties of LCMO/NFO composites were investigated using X-ray diffraction, scanning electron microscopy, field cooled DC magnetization, and magnetoresistance (MR) measurements. The resistivity measured as a function temperature demonstrates that the pure LCMO and x = 0.01 samples display metal to semiconductor transitions. However, the composites of x > 0.03 samples clearly present the electrical behavior as an insulator/semiconductor type behavior. It was observed that the resistivity of the samples increased systemically with an increase of the NFO content. From the MR measurements, it was found that the MR effect is enhanced for x = 0.01 with a NFO composition. In all, the spin-polarized tunneling and the spin-dependent scattering may be beneficial for an improved lowfield magnetoresistance effect. These phenomena can be explained by the segregation of a new phase related to NFO at the grain boundaries or surfaces of the LCMO grains.

Effects of Obesity on Prostate Volume and Lower Urinary Tract Symptoms in Korean Men
김근우,두승환,양원재,송윤섭 대한비뇨의학회 2010 Investigative and Clinical Urology Vol.51 No.5
Purpose: We investigated the effects of obesity on prostate volume (PV) and lower urinary tract symptoms (LUTS) in Korean men. Materials and Methods: From December 2007 to 2009, a total of 10,383 ostensibly healthy Korean men aged ≥50 years visited our health promotion center for a routine check-up. Among them, 872 men who wanted a prostate evaluation were enrolled in this study. All men underwent detailed clinical evaluations with the International Prostate Symptom Score (IPSS) questionnaire. Anthropometric measurements, including height, weight, and waist and hip circumferences, were determined. A blood sample was obtained for serum prostate-specific antigen (PSA) measurement. Thereafter, a digital rectal examination and transrectal ultrasound were performed. Results: In total, 465 men with moderate to severe LUTS (IPSS≥8 points) were included in this prospective study. The participants’ mean age was 57.2 years. Multivariate analysis demonstrated that only waist circumference was a significant factor in predicting PV besides age and serum PSA. The univariate analysis showed no statistically significant relations between any of the obesity-related parameters and LUTS. The PV was also not correlated with LUTS. Conclusions: Central obesity is the more important predictor of PV than overall obesity. There are no significant relations between obesity-related parameters and LUTS.

=목 적: 미분화 줄기 세포를 골 조직 유도 촉진제 사용 없이 직접 동종 이식 시 골 형성의 정도를 알아보았다.대상 및 방법: 성장 중인 백색 가토를 대상으로 경골 부분 절제술 후 이식 물질에 따라 제1군(줄기 세포와 agar), 제2군(agar), 제3군(골 절제술만 시행)으로 나누었다. 8주에 걸쳐 매주 단순 방사선 검사 후 가토를 희생시켜 신생 골의 조직 검사를 시행하였다. 형성된 골 조직이 이식한 줄기 세포에 의한 것임을 증명하고자 줄기 세포를 CM-Dil로 표시시켜 골세포에서 형광 발현 여부를 확인하였다.결 과: 골수와 인접한 부위에서 섬유 모세포와 골모세포로 분화되는 세포들이 전자현미경 상 관찰되었다. 골막 및 골수 강에서 유래한 골세포에 의한 연골내 골화와 줄기 세포에서 분화된 골모세포에서 형성된 유골이 함께 관찰되었다. 이식 6주째까지 형광을 발현하는 세포를 신생 골 조직 내에서 관찰할 수 있어 새로 형성된 골은 이식한 줄기 세포에서 기원함을 알 수 있었다.

The waste-to-energy (WTE) industry draws global attention by using wastes as energy resources. Korean government is very inclined to invest in the WTE industry. Therefore, it is believed that there will be an industrial scale-up. Also it is needed to make proper strategies for promoting the industry by creating the added value of related companies. This study analyzes whether the value-added structure of Korean WTE industry exhibits a virtuous cycle through the value chain (VC) within related companies by using a regression analysis based on a survey to Korean WTE companies. As a result, the government’s R&D support is analysed not to contribute to an increase in the R&D investments of the WTE companies. Also an increase in corporates’ R&D investments does not lead to an increase in corporates’ R&D outputs. An increase in corporates’ R&D outputs, however, has the positive influence on an increase in production. In contrast, an increase in production does not have an effect on a decrease in production costs. And a decrease in production costs does not lead to an increase in profit rates per sales. In addition, it is shown that an increase in profit rates per sales does not contribute to an increase in production and R&D investments. Therefore, it is estimated that the Korean WTE companies do not organize the virtuous cycle of the VC yet. This study has a policy implication to need further efforts to create the virtuous cycle in the VC of Korean WTE industry.

공동주택 개발 사업의 비용분석을 위한 시스템 다이내믹스 모델 개발 연구
김근우,윤석헌 한국건축시공학회 2011 한국건축시공학회지 Vol.11 No.3
This study is on the development of a System Dynamics Model for business feasibility analysis of an apartment house development project. In this study, we analyzed other apartment development projects and research projects, and identified the cash flow items, which consist of revenue and expenditure items. In addition, we made efforts to find the influence relationship among these using the system thinking method and developed a system dynamics model. In order to test the model, a case study was conducted in which it was applied to an apartment development project. Vensim,a System Dynamics Modeling and simulation software package was used to analyze and test the model. The model suggested in this study can help a developer to make decisions on project financing at the initial stage of an apartment house development project. 본 연구에서는 아파트 개발 사업의 타당성 분석을 위한시스템다이내믹스 모델을 개발하고 사례연구를 수행하고자하였다. 연구에서는 기존의 아파트개발 사업 사례와 연구프로젝트 자료들을 근거로 현금흐름 구성요소들을 도출하였고, 시스템사고 방법과 시스템다이내믹스 모델을 사용하여 이들 요소의 상호 영향관계를 찾고자 노력하였다. 연구에서는 모델을 정의하고 분석하기 위해 Vensim이라는 시스이내믹스 소프트웨어를 사용하였다. 이렇게 도출된 모델을 검증하기 위해 사례 연구를 진행하였으며, 사례연구 결과 연구에서 개발한 모델이 실제 프로젝트에 적용이 가능할 것으로 판단되었다. 연구에서 도출된 모델은 아파트 개발사업자들이 프로젝트의 초기단계에 프로젝트 파이낸싱과관련한 의사결정에 도움이 될 수 있을 것으로 판단된다.
