Alcohol consumption and exposure to endocrine disruptors and industrial solvents have been implicated in impaired spermatogenesis, increase in the incidence of malformed sperm and decrease in the percentage of moving sperm. The aim of this study was to determine and compare the direct effects of some organic solvents(bisphenol A; BPA, dibutyl phthalate; DBP, formaldehyde; HCHO, dimethylsulphoxide; DMSO, ethanol) on mucus penetration distance, motility and survival rate of human sperm in vitro. Semen samples from 3 health subjects were prepared using swim-up method and 0.0005~0.5% organic solvents were added to the test medium. BPA, DBP, HCHO and DMSO produced significant decreases in the motility and survival rate with a different potency. The most potent inhibition of mucus penetration distance, motility and survival rate was observed after exposure to HCHO. A concentration of 0.0005% HCHO significantly inhibited sperm motility. When ethanol is added directly to sperm, at concentrations equivalent to that in serum after heavy drinking, these damaging effects were lowest compared with other solvents. Present study shows that each compound has different toxic potency to human sperm and we need special caution for the use of HCHO.

본 연구는 로쓰만의 지역성개발모형의 추진전략을 부산희망세상 사례연구를 통해 확장성을 탐색한 연구이다. 사례분석을 통해 부산희망세상은 활동가 투입, 주민리더 발굴, 주민조직 구축을 통해 내부지향형 지역성개발모형을 추구해갔으며, 이를 통해 축적된 역량을 중심으로 수평적 연결형 지역성개발사업과 수직적 연결형 지역성개발사업을 함께 추진해 나간 것으로 분석되었다. 이를 통해 로쓰만의 지역성개발모형은 주민조직화를 통해 추진해나가야 안정성을 확보할 수 있으며, 안정적 조직역량을 바탕으로 수평적 네트워크와 수직적 네트워크를 동시에 추진할 수 있음을 확인했다. This research explores implementing strategies for Locality Development Model through resident organization using the case study on Busan Hope Society. Rothman's strategies of community intervention is consulted for theoretical background. Based on case analysis Busan Hope Society pursuits inner-directed locality development model through inputs of activists, finding resident leaders, and building resident organization. Busan Hope Society, with accumulated capacity through these activities, promotes both horizontally-connected locality development projects and vertically-connected locality development projects. This study finds out Rothman's Locality Development Model could secure stability through resident organization, and both horizontally-connected networks and vertically-connected networks could be promoted simultaneously through stable organizational capability.

장애인 취업알선 서비스가 고용의 질에 미치는 영향

유동철 한국장애인고용촉진공단 고용개발원 2008 장애와 고용 Vol.18 No.1

The purpose of this study is to analyze empirically the effects of job placement services on quality of work of the people with disabilities. In order to pursue such goal this study used ‘the disabled workers survey data’conducted by KEPAD(Korea Employment Promotion Agency for the Disabled) in 2005. The data were analysed by logit, multiple regression analysis. The major findings are: (1) The disabled who were helped by job placement service center had higher probability in employment at large enterprises than not helped. (2) Job placement services increased the probability of irregular employment. (3) Job placement services decreased the wage per hour. According to the findings of this study, I recommended to introduce One-Stop Career Service Delivery System based on Employment Support Center, and case management system, to encrease co-work of KEPAD and Employment Support Center, and to re-classify the work rehabilitation center by transitional employment level. 본 연구는 장애인에 대한 공공서비스 중 취업알선서비스가 장애인의 고용의 질에 미치는 영향을 실증적으로 분석하기 위한 것이다. 자료는 2005년 한국장애인고용촉진공단에서 조사한‘장애인근로자 실태조사’원자료를 이용하였다. 분석 결과 취업알선 서비스를 받은 장애인의 경우 스스로 알아서 취업한 장애인에 비해 300인 이상 사업체에 취업할 확률은 높아지나 임시·일용직에 취업할 확률 또한 높아지는 것으로 나타났으며, 임금은 오히려 취업알선 서비스를 받지 않은 장애인근로자에 비해 더 낮은 것으로 나타났다. 이러한 문제를 극복하기 위해 고용지원센터를 중심으로 한 원-스탑 서비스 전달체계의 구축, 사례관리팀의 구성, 직업재활실시기관의 기능별 재분류를 통한 고용 기능의 강화 등의 정책적 대안을 제시하였다.

Possible Health Effects of Caffeinated Coffee Consumption on Alzheimer's Disease and Cardiovascular Disease

유동철,김영순,하애화,이유나,김수민,김천흠,이승하,최달웅,이재민 한국독성학회 2011 Toxicological Research Vol.27 No.1

Coffee has been known to have both beneficial and harmful effects upon health. Coffee is one of the most widely consumed beverages, worldwide. Dementia/Alzheimer’s disease (AD) and cardiovascular disease (CVD) are public health problems that are rapidly increasing in the aging population. Due to the high consumption of coffee, even small effects on an individual’s health could have a large effect on public health. The aim of this review article is to provide an overview of previously published studies of coffee consumption on health. Herein, we focus on epidemiological and experimental findings to investigate whether coffee-drinking habits, and/or the quantity of coffee consumption, have any relationship to CVD, dementia/AD, and other chronic diseases. Although the underlying mechanisms are not fully understood, when comparing coffee drinkers with non-drinkers, moderate doses of caffeine showed protective effects against CVD and AD. We hypothesized that caffeine may be a novel therapy to treat CVD and dementia/AD.

The purpose of this study is to develop a prediction model that can evaluate energy consumption before and after remodeling through a reference model for low-rise residential buildings for which energy simulation evaluation is difficult due to its aging. Specifically, a prediction model to evaluate various building elements before remodeling and a model to predict savings due to the application of energy-saving technology were developed. For the objective, the energy simulation analysis of a building was performed using DesignBuilder per reference area of a Detached house, Multi-family house, and Row House. In addition, the significance of machine learning was compared and analyzed by using R2 , MSE, RMSE, CVRMSE indicators and Python’s linear regression, random forest, and neural network. As a result of this analysis, both the model to evaluate the status before remodeling and the model to evaluate the reduction rate according to the energy-saving technology after remodeling showed a high determination coefficient of 0.9 or more for the neuron network. The CVRMSE was analyzed as low as 15% or less. As this is less than the index used in the M&V evaluation presented in the ASHRAE Guideline 14, it was verified that there is a statistical significance. Therefore, this aims to contribute to the basic data and green remodeling promotion project in the energy performance improvement project for the old, private low-rise residential buildings and also in the energy-saving evaluation for buildings.

장애인복지서비스의 지방이양에 따른 장애인단체의 역할

유동철 한국장애인복지학회 2005 한국장애인복지학 Vol.- No.2

This study is to look over the trends of the transfer of the welfare services to the local authority from the central government, to anticipate the effects of transfer, and to suggest the roles of the organizations of the people with disabilities. This year 67 services among 138 services of the Ministry of Health and Welfare is transferred to the local authority. Among the 67 services, 24 services are services for the people with disabilities. And the remain services would be transformed into block grants Theses trends of the transfer would have negative and affirmative effects simultaneously. The affirmative ones would be like as followings: increase of the autonomy of the local authority, increase of the efficiency of total budget, expansion of the welfare services in consideration of the citizens of the local area, and possibility of expansion of the budget for welfare services. At the same time negative effects are anticipated like possibility of deduction of the budget for welfare services, expansion of the gap between local authorities and welfare service categories besides. To keep away from the negative ones, and to promote the affirmative ones, organizations of the people with disabilities should try to construct local governance through local committee of the welfare for the people with disabilities and local welfare council, to strengthen the solidarity between general nongovernment organizations, to participate in the process of the budget making, and to reconstruct the role between the organizations of the people with disabilities. 이 연구는 장애인복지서비스의 지방이양 실태를 살펴보고 지방이양이 가져올 긍정적인 효과와 부정적인 효과를 전망한 후 이에 따른 장애인단체의 역할을 제안하는 것을 목적으로 한다. 올해부터 67개의 보건복지부 업무가 지방으로 이양되었다. 이 중 장애인복지서비스는 총24개로서 수치상 가장 많은 비중을 차지하고 있다. 이와 같은 사회복지서비스의 지방이양은 긍정적인 효과와 부정적인 효과가 동시에 있을 것으로 전망된다. 긍정적 효과로는 지방정부의 자율성 확장, 예산의 효율성 증대, 지역밀착형 복지의 실현, 사회복지 예산 증가의 가능성 등이 지적되었고, 부정적 효과로는 사회복지재정의 축소 가능성, 지방정부간 불평등 확대, 복지부문간 불평등 확대 등을 지적했다. 그리고 이에 대해 장애인단체에서는 지역협치의 구축, 시민사회단체와의 연대, 지방 예산과정에의 적극적 참여, 장애인단체의 역할 분담 재정립 등을 통해 적극적으로 대처해 나가야 한다고 주장했다.
