The purpose of this study was to confirm the complex relationship between patient safety-medical quality and hospital management activities to observe the mediating effect of organizational culture in the relationship due to healthcare accreditation adoption. For this, we conducted a 4 weeks survey, from September 22, 2014 to October 17, 2014 to the employees of 6 hospitals that could accommodate less than 300 patients or more than 300 patients located in Daegu and Gyeongbuk. The study includes 377 participants who have worked for more than one year in the hospital. All of hospital with less than 300-beds or more than 300-beds, such as patient safety-medical quality, organizational culture, hospital management activities found a positive correlation among variables. The mediating effect of organizational culture in the relationship between patient safety-medical quality and hospital management activities was shown by the partial mediating effect and high causal effect. Therefore, these study suggest that patient safety-medical quality due to healthcare accreditation adoption has the potential to improve hospital management activities.

The automatic analysis of high-resolution satellite image is important in cartography, surveillance, exploiting resources etc. However, the automatic analysis of high resolution satellite image in the urban area has lots of difficulty including a shadow, the difference of illumination with time, the complexity of image so that the present techniques are seemed to be impossible to resolve. This paper proposes a new way of change detection of building objects in urban area, in which the objects in digital vector map are designated and superimposed on the the high-resolution satellite image. The proposed way makes the buildings on the vector map parameterize, and searches them in the preprocessed high-resolution satellite image by using generalized Hough transform. The designated building objects are overlaid on the satellite image and the result can help to search the changes in building objects rapidly.

This study investigates the relationship between fear of failure of potential entrepreneur's psychological characteristics and entrepreneurial intentions using the mediation variables of planned behavior model. There are many existing prior research related to the entrepreneurial intentions, but they were mostly focused only entrepreneurial success factors. So in this study we focused on fear of failure of potential entrepreneur. To know the influence of the fear of failure related to entrepreneurial intention, we using the scale of PFAI (Performances Failure Appraisal Inventory). The purpose of this study is to examine an impact of fear of failure on entrepreneurial intention and add to mediating factors - attitude toward the acts, subjective norm, perceived behavior control - on the relationship between fear of failure and entrepreneurial intention. Also we examined entrepreneurial education as moderating effect in order to offset the fear of failure. In order to test research model, we collected data from 321 undergraduate students. To test the research questions and hypotheses, we employed SPSS 21.0 anf AMOS 18.0 for validity, reliability, confirmatory factor analysis, and structural model analysis. The results were as follows. First, the fear of failure negatively related to attitude toward the behavior and subjective norm. Second, attitude toward the behavior and subjective norm positively related to entrepreneurial intention in consistent with previous studies. Third, attitude toward the acts and subjective norm in TPB variables have full-mediation effects between fear of failure and intrepreneurial intention. Fourth, The moderating effects of entrepreneurial effect was not significant. The negative relationship between fear of failure and attitude toward the acts and subjective norm was even slightly stronger who have taken the entrepreneurial class group. We discuss the theoretical and managerial implications, and provide suggestions for future research.

The aim of this study is to enhance the level of life satisfaction of the elderly as the aging population grows in readiness for increased old age, beginning with interest in improving the quality of life of the elderly. For this purpose, the subtype of preparation for aging was set as multi-independent variables by organizing it into physical preparation for aging, economic preparation for aging, and emotional & social preparation for aging. Structural relationships between variables was identified by social support a parameter variable and life satisfaction a dependent variable. It was also verified that the social support between subtypes of preparation for aging and life satisfaction had a mediating effect. The subjects of this study are 4,058 elderly people who are over the age of 65. They were originally extracted from the 3rd and 5th additional survey of Korean Retirement and Income Study. For data analysis purposes, SPSS 25.0 and SPSS PROCESS macro v2.16 were used. The results of this study are as followed. The emotional & social preparation for aging not only had a significant direct effect on successful aging, but also resulted in indirect effect on successful aging through life satisfaction. On the basis of the results, this study provided the social welfare policy and practical suggestions to enhance the preparation for aging and social support, which are the key to improving life satisfaction of the elderly.

As the social economy emerges as one of the alternatives for solving social problems, interest and experiments on social franchise, a methodology for scaling the social economy, continue to increase. The success or failure of social franchise has a huge impact on franchisors, members of franchisees, as well as beneficiaries, local residents, and stakeholders in the region, but research on ways to increase their chances of success is still insufficient. Based on previous studies, this study tried to derive success factors by analyzing the effects of social franchise characteristics on business performance, and to understand the mediating effect of franchise autonomy, which is the differentiation point of social franchises, between characteristic factors and business performance. Social value orientation, social economy experience, local network utilization, and customer orientation were derived as characteristic factors affecting business performance, and franchise autonomy was set as a mediating variable, and a survey was conducted for franchisee members and their influence was analyzed. Through this study, it was found that social economy experience and local network utilization had a positive (+) effect on economic performance, and social value orientation, local network utilization, and customer orientation had a positive (+) effect on social performance. Also, the results of franchise autonomy playing a mediating role between social economy experience, local network utilization and economic performance, and a mediating role between local network utilization and social performance were presented. This study has significance as the first study to conduct a full-scale empirical study on social franchises. It is hoped that theoretical research on social franchises will be more active in the future and will be used as a useful reference for performance creation for organizations that seek or already operate social franchises.

The study aims to examine the interaction of socio-economic status in education and income in the difference of the level of subjective health, physical health, and mental health of middle-age and the elderly of Korea. While there have been various discussions in precedent study with respect to the serious increase in the number of dependent life alongside with increasing elderly population, research on the health level according to socio-economic status is highly limited, and also how the health level of middle-age and the elderly - whom will arrive at senescence in just a few years - is different. The study aims at analyzing the health level by hierarchy and age based on data targeting the whole nation. As for analysis data, the study utilized 1st Korean Longitudinal Study of Ageing (KLoSA) implemented by Korea Labor Institute, and carried out a path analysis to verify whether income and academic background serve as a parameter to the level of subjective health, physical health, and mental health. As a result, while the subjective health level decreases, the study confirmed an increase in chronic diseases, and extremely low level of mental health when people in middle-age enter the elderly. In addition, the higher the education and income, the more the health levels both on middle-age and the elderly; the result suggests that education background and income have mediated effects in all health level of middle-age and the elderly.

지금까지 우리나라에서는 도시하수, 공장폐수 등의 점오염원에 국한하여 중점적으로 수질관리를 실행하여 부분적으로 효과를 얻을 수 있었으나, 하천과 호소의 수질은 크게 향상되지 않고 있다. 이는 급속한 도시화와 산업발달로 토지개발이 가속화되고 대지, 도로, 주차장 등 불투수층 면적이 늘어남에 따라 비점오염원에 의한 하천, 호소의 수질영향도가 커지고 있기 때문이다. 인구증가로 인해 물 사용량 뿐만 아니라 이에 따라 배출되는 오염원의 종류 및 오염부하량 역시 함께 증가하고 있다. 장래의 수질관리 성공여부는 비점오염원의 효율적인 관리여부가 큰 변수로 작용할 것으로 본다. 따라서 공공수역의 수질관리를 위해서는 토지이용과 지역특성을 고려한 비점오염원 부하량의 합리적인 조사, 오염 부하량 절감을 위한 관리기술의 개발, 비점오염원 관리정책의 개발 및 수질모형을 이용한 정확한 수질예측 등이 필요하다. 따라서 본 연구에서는 공간정보를 바탕으로 한 낙동강 유역에서의 비점오염원 정량화 분석을 수행하고자 한다. 우선 대상유역으로 낙본 G유역을 선정하여 이에 대한 조사를 통해 점오염원의 실측자료를 구축하고 이를 HSPF의 입력하여 모의를 수행하여 대상유역에 대한 실측치를 이용해 모형의 보정과 검증을 수행한다. 이러한 과정을 통해 도출된 결과는 대상유역의 총 오염량을 의미한다. 따라서 위의 과정에서 도출된 매개변수를 이용하고, 점오염원을 제거한 뒤 모의를 재수행하여 나온 결과가 대상유역의 비점오염원의 양이라 판단하였다. 모의 결과 대상유역인 낙본 G유역에서 약 39% 정도의 비점오염원 비율을 보였다. 그러나 수질 및 유량 관측치를 지금까지는 국립환경과학원 낙동강물환경연구소 유량측정데이타를 사용하고 있는데 이 자료는 8일 이상 간헐적으로 측정이 수행되고 있다. 따라서 검 보정 대상이 되는 실측치의 자료의 부족과 부정확한 유역이 있음이 한계점으로 작용한다. 그러므로 추후의 신경망 모형이나 기타 실측치 보간에 있어서의 신뢰도를 높이는 기법 개발이나 측정제도의 보편적인 기술의 증대도 앞으로의 모델링에 있어서 중요할 것으로 판단된다. 또한 유역수질모형의 모델링 과정에서 좀 더 신뢰도 높은 측정자료와 그 측정자료를 활용하여 PEST 보정기법을 적용한다면 더욱 정확한 예측이 이루어질 수 있을 것이며, 본 연구에서의 평가방법을 바탕으로 유역수질모델링이 이루어진다면 보다 더 정확성 높은 비점오염원 정량화와 수질 예측이 수행될 수 있을 것이며 더 나아가 오염총량제의 수행에 효과적으로 적용될 것으로 판단된다.

This paper deals with an Umbrealla Arch Reinforcement Method (UARM) in tunnelling. It is known that the mechanism of the reinforcement system is too complex to be simulated in existent finite element (FE) frameworks when considering its complex geometry of pipe arrangements and contribution of each component of the reinforcement to reinforcing effect. In this study a 3-D elastoplastic FE procedure is, therefore, proposed by introducing homogenisation technique, which is used to define mathematically elastic as well as elastoplastic characteristics of a reinforced ground material as a composite. A number of practical suggestions are addressed considering staged constructions of tunnels. For illustrative purposes, a series of parametric studies are undertaken and anisotropic characteristics of the reinforced ground as well as effects of the reinforcement on tunnel convergences are investigated. It is found that the reinforced ground material defined in homogenisation framework has its mechanical characteristics reasonably representing inherent geometrical and quantitative characteristics of each of constituents.

In this paper, a new regularization method by parameter subset selection method is proposed based on the residual force vector for damage localization. Although subset selection using the fundamental modal characteristics as a residual function has been successful in detecting a single damage location, this method seems to have limited capabilities in the detection of multiple damage locations and typically requires cumbersome weighting values. The method is presented herein and considers cases in which damage detection must be achieved using incomplete measurements of the structural responses. Model expansion is incorporated to deal with this challenge. The unique advantage of employing the new regularization method is that it can reliably identify multiple damage locations. Through an illustrative example, the proposed damage detection method is demonstrated to be a reliable tool for identifying multiple damage locations for a planar truss structure.
