Objective : In this study, we investigated the prevalence of depression and its impact on the healthrelated Quality of life (HRQoL) of the patients with End-Stage Renal Disease (ESRD) on Hemodialysis. Method : The Quality of life (QOL) of patients was evaluated by HRQoL Questionnaire, "Medical Outcome Survey 36-Item Short Form Health Survey Korean Version (SF-36-K)". The patients on Hemodialysis in ESRD, were chosen from the hemodialytic room at Wonkwang University and Jeongeup-Asan Hospital. The number of patients was 95 (64 from Wonkwang University Hospital and 31 from Jeongeup-Asan Hospital) and all of them were above 19 years old. We performed various investigations to find a statistical correlations between HRQoL and physical & psychosocial factors such as the demographic characteristics, clinical characteristics (hemoglobin level and albumin level etc), and the score of Beck's depressive inventory (BDI). Results : The HRQoL value of patients on hemodialysis in ESRD is far poorer than the HRQoL reference value of Koreans and Americans, who are in normal healthly. The prevalence of depressive symptoms by BDI of the ESRD patients on hemodialysis is 68.6%, and age and depression have negative correlations with HRQoL of the patients. However, education level, serum albumin level, and social support have positive correlations with HRQoL. The patient group with depression has significantly poorer HRQoL than the group without depression. Conclusion : The HRQoL of ESRD patients on hemodialysis is not good in both physical and mental aspects. The prevalence of depression is very high and depression has negative impact of HRQoL of patients. Based on our study, it is essential to accompany with therapeutic Strategy to improve the HRQoL of ESRD patients on hemodialysis.

The aim of this study was to understand the mechanisms that allow mSSC lines to be established from SSCs. Small, multilayer clumps of SSCs formed during two to four weeks of in vitro culture and were then transferred to MEF feeders. Small, round, monolayer colonies containing cells destined to convert to mSSCs, designated as intermediate state SSCs (iSSCs), first appeared after two to three pas-sages. During an additional nine passages (47-54 days) under the same culture conditions, iSSCs slowly prolifer-ated and maintained their morphology. Ultimately, a cell type with an ES-like morphology (mSSC) appeared from the iSSC colonies, and two mSSC cell lines were estab-lished. The mSSCs had a high proliferative potential in serum-free ES culture medium and have been successfully maintained since their first establishment (> 12 months). We also compared the specific characteristics of iSSCs with those of SSCs and mSSCs using immunocytochemis-try, FACS, RT-PCR, DNA methylation, and miRNA analyses. The results suggest that iSSCs represent a morphologi-cally distinct intermediate state with characteristic expres-sion patterns of pluripotency-related genes and miRNAs that arise during the conversion of SSCs into mSSCs. Our results suggest that iSSCs could be a useful model for evaluating and understanding the initiation mechanisms of cell reprogramming.

The exploitation of technologies based on electro spinning have been limited due to poor understanding of the process and consequent limitation in process control, productivity and reproducibility. To control the effect of the environmental parameter, which is one of important electro spinning parameters, the vacuum process was introduced because the magnitude of electric field in vacuum is not limited by the low dielectric breakdown strength of air. For this study, PCL dissolved in a mixture of N,N-dimethylformamide (DMF) and methylene chloride (MC) was electrospun as a form of nonwoven mats consisting of nano-sized fibers under vacuum and they have been analyzed using SEM and DSC. The PCL nonwoven mats via electrospinning under vacuum showed the characteristic spinning behavior observed at atmospheric pressure. In addition, results obtained from tensile test showed that PCL nonwoven mats via electro­spinning under vacuum have better mechanical properties than those prepared at atmospheric pressure.

도시공원의 공간적 불균형 분석을 통한 공급적정성 평가

김형준,정성관,이우성,Kim, Hyoung-Jun,Jung, Sung-Gwan,Lee, Woo-Sung 한국조경학회 2011 韓國造景學會誌 Vol.39 No.4

최근 환경친화적이고 지속가능한 도시 건설을 위한 도시공원 입지의 중요성이 증대되고 있으며, 바람직한 도시공원 조성을 위해서는 공급적정성 평가와 입지 선정 방법에 대한 정확한 이해와 접근 방법이 필요하다. 그러나 현재까지 우리나라 도시공원의 공간적 불균형과 입지계획에 대한 연구는 미흡한 실정이다. 이에 본 연구에서는 대구광역시 수성구 황금동을 대상으로 도시공원의 공간적인 불균형을 평가하고 부족지역을 추정하였으며, 불균형 해결을 위한 정책적 제언을 하였다. 분석결과를 살펴보면, 황금 1동과 2동의 도시공원 법적 요구량은 각각 943.08$m^2$/GRID, 380.61$m^2$/GRID로 나타났으며, 2개 근린공원과 4개 어린이공원으로부터 제공되는 총 서비스 제공량은 각각 406,730.80$m^2$, 157,086.40$m^2$로 분석되었다. 이를 토대로 황금동 전체의 공급적정면적을 평가한 결과, 법적 제공면적 이하의 도시공원을 제공받는 지역은 황금 1동이 12.3%, 황금 2동이 51.5%로 나타났다. 한편, 주거지역을 대상으로 도시공원의 공급적정성을 평가한 결과에서는 "매우 충족"한 지역이 황금 1동 20.5%, 황금 2동 5.4%로 나타난 반면, "매우 부족"한 지역은 황금 1동 27.6%, 황금 2동이 10.8%로 분석되며, 도시공원이 부족한 것으로 평가된 지역은 면적, 형태 등을 고려한 공원의 추가조성이 필요할 것으로 사료된다. 이러한 공급적정성 평가 결과는 도시공원 업지의 문제점을 파악하고, 해결하기 위한 도구로써의 역할뿐만 아니라, 환경친화적이고 지속가능한 도시건설을 위한 공원기본계획의 기초자료로써 활용 가능할 것으로 판단된다. Recently, the location of urban parks has become more important in terms of the construction of an environment-friendly, sustainable city. To build a refined and desirable urban park, it is necessary to have precise understanding on the evaluation of supply adequacy and selection method for its location. However, there have been few studies on the spatial imbalance and location plan of urban parks. Therefore, this study has attempted to evaluate the spatial imbalance of urban parks in Hwanggeum-dong, Suseong-gu in Daegu and propose a policy suggestion to solve the imbalance. According to the analysis, Hwanggeum 1-dong and 2-dong recorded 943.08$m^2$/GRID and 380.61$m^2$/GRID, respectively, in terms of legal requirements for urban parks and 406,730.80$m^2$ and 157,086.40$m^2$ in terms of total service supply from two neighborhood parks and four children's parks. According to the evaluation of optimal supply area across Hwanggeum-dong, Hwanggeum 1-dong and 2-dong recorded 12.3% and 51.5%, respectively. In an evaluation of the supply adequacy of urban parks, the areas described as 'very satisfying' were 20.5% and 5.4% in Hwanggeum 1-dong and 2-dong, respectively. On the contrary, the areas described as 'very dissatisfying' accounted for 27.6% and 10.8%, respectively, in the two regions. It appears that additional parks should be developed in the inferior areas in terms of urban parks in consideration of various factors such as area and shape. The results of the supply adequacy evaluation will be used as a tool to figure out and solve problems in the location of urban parks and as basic data for a master plan to build an environment-friendly, sustainable city.

Numerical Analysis for exchanging seawater experiment is carried out in Do-Jang fish port. The change of tidal velocity and water level is derived by the two-dimensional nonlinear shallow-water numerical model. To calculate exchange rate of seawater with the change of tidal velocity and water level, a two-dimensional numerical model is employed which governing equations are Fokker-Plank equations. The calculated exchange rates of each time are described in tables and figures.

실거래가격 분석을 통한 비주거용 부동산의 과세형평성 연구

김형준,Kim, Hyoung June 한국데이터정보과학회 2016 한국데이터정보과학회지 Vol.27 No.3

2016년 1월 19일자로 전부개정 (2016년 9월 1일자 시행)된 "부동산 가격공시에 관한 법률 (이하 부동산공시법)"은 처음으로 "비주거용 부동산 가격공시"제도 도입을 결정하였다. 하지만 현행 비주거용 부동산 과표에 대한 많은 문제 제기에도 불구하고 비주거용 부동산 제도 도입에 따른 방법론이 아직까지 구체화되지 않았고 과표 변경에 따른 정부의 부담으로 그 도입 시기가 연기 될 것으로 보인다. 이에 최근 논의가 활발히 진행되고 있는 현행 공시제도의 실거래기반 공시제도로의 전환과 관련하여 1개 연도 전체 실거래가격을 분석하여 비주거용 일반 부동산에 대한 과세 형평성을 살펴보고 과표에 영향을 미치는 주요 요인이 무엇인지 분석한 연구로 실거래가를 활용하여 비주거용 부동산에 적용한 최초의 연구이다. "Law on price announcement for real estate" which was revised as of Jan. 19, 2016 (will be enforced as of Sep. 1, 2016) decided the introduction of 'Price announcement system for non-residential property' for the first time. However, its introduction seems to be delayed based on two reasons. Firstly the methodology for introduction of non-property system is not definitized, despite many problems were brought up for current tax base of non-residential property. In addition, changes in tax base will place a burden on the government. In this regard, this study analyzed actual transaction price data throughout one year to analyze equity of taxation for non-residential property and to find major factor which affects on the tax base, in relation with the change of current public announcement system to actual transaction based system. And this is the first study that applied actual transaction price to non-residential property.

New polyimine derivative containing fluorene group in the main chain was synthesized via Suzuki cross-coupling polymerization, reduction, and imine formation reaction, consecutively. The synthesized polymer was characterized and explored as organic photovoltaic cell device. The imine polymer P3 in diluted chloroform solution emitted red light (582 nm), whereas its precursor polymers P1 and P2 showed green (about 530 nm) and blue fluorescence (477 nm), respectively. Bulk heterojunction photovoltaic cells fabricated by blending P3 with the fullerene derivative PCBM was found to have a power conversion efficiency of upto 0.0005%, while cells from blending P3 with MEH-PPV yielded 0.0008% of power conversion efficiency.
