This case study introduces the process of developing the technology rating evaluation model for investment. The technology evaluation rating model for investment is a project that the Financial Services Commission and the Ministry of Commerce, Industry and Energy collaborated to expand the scope of technology finance from loan to investment. The technology evaluation model for investment was developed with the aim of predicting high growth companies. The model consists of a statistical model and an expert model. Here, statistical models were modeled by using logistic regression analysis. Expert models gathered opinions of experts and identified the weight of each evaluation item and set the model. The rating system of the model is composed of 10 grades. The distribution of the model was consistent with KTRS grade distribution. Interestingly, the emphasis is on technology and marketability. In the technology valuation grade model for the goddess, there is a considerable difference from the emphasis on managerial competence or business performance.

자연재해 중 홍수의 경우 단기간에 발생하며, 큰 인명 및 금전적 피해를 가져오는 재해이다. 1970년~2017년 국내 홍수 피해 분석결과 사상자(총 8,152명)는 점차 줄어드는 추세를 보이지만, 반대로 피해액(총 17조5,000억원)은 증가하는 것으로 나타났다(wamis, 국가수자원관리종합정보시스템). 이러한 국내 홍수 피해를 최소화하기 위해서는 각 유역 또는 지역별 특성을 고려한 홍수 취약성 평가가 필요하다. 홍수 취약성은 대상 지역의 기상, 지형, 인문학적 상황에 따라 상이하게 나타나며, 홍수 취약성을 평가하는 인자의 선정 또한 매우 중요하다. 따라서 본 연구에서는 홍수 피해 자료와 홍수 인자간의 인과관계를 분석하여 홍수 취약성 지표 선정 및 취약성 평가를 실시하였다. 홍수 취약성 평가를 위해 홍수 피해 자료와 대상 인자간의 상관성 분석을 통해 상관계수 값이 상대적으로 높게 나온 인자를 선정하였다. 대상 인자는 크게 기상학적 인자, 지형학적 인자, 사회·인문학적 인자로 구분하였다 선정된 인자 간 서로 높은 상관성을 보일 시 공선성이 존재함을 의미하며, 이러한 공선성을 방지하기 위해 VIF (Variance Inflation Factor, 분산팽창계수)를 통한 공선성 검토를 적용하였다. 또한 각 인자 간 에는 서로 다른 단위 및 범위를 가진다. 이러한 경우 특정 인자들의 증감을 취약성 평가에 반영하기에 어려움이 있으며, 유역별 평가 시 신뢰성이 낮아진다. 따라서 Re-scaling 방법을 통해 각 인자의 단위 및 범위를 표준화 후 동일가중치 법을 적용하였다. 본 연구에서는 전체 유역 중 홍수피해가 가장 크게 발생하는 낙동강 태화강 유역을 연구 대상 지역으로 선정하였다. 태화강은 도심지의 중심부를 흐르는 하천이며, 산지의 고도가 높은 지형적 특성을 가지고 있어 홍수에 대한 취약성이 높은 것으로 나타났다(wamis, 국가수자원관리종합정보시스템). 태화강 유역 홍수 취약성 평가결과 유역별 기상, 지형, 인문학적 특성에 따라 홍수 취약성이 높게 나타나는 결과를 보였다. 이와 같은 결과는 유역 내 도심지 비율, 인구밀도, 토지피복 특성에 의한 것으로 주로 지형학적 인자로 인해 취약성이 높게 나타났다. 본 연구에서 활용한 홍수 취약성 평가 방법은 향후 홍수피해 대책 수립에 사용될 수 있을 것으로 판단된다.

This study classifies the types of urban railway stations that reflect the location characteristics of urban railway stations, the structure and form of station taxes, and the number of users, and the level of inconvenience in the transfer movement line for users by station type, the number and connectivity of transfer information, and the level of transfer convenience facilities. The number of installations, conflicts between users, and transfer information signs were analyzed. As a result of data analysis, it was found that the factors that cause the most inconvenience to urban rail users when transferring are the length and curvature of the transfer line, pedestrian density and number of passengers in the transfer passage, presence or absence of transportation convenience facilities, and the size and height of transfer information letters. These transfer inconveniences were objectified, quantified, and presented as evaluation indicators that can measure the transfer convenience of urban railway stations. Additionally, an evaluation scale was developed to measure the service level for each evaluation indicator. The evaluation scale for each indicator presented six levels by applying linear interpolation based on the maximum and minimum values of data derived through field surveys. However, it is judged that a comprehensive evaluation of transfer convenience that combines the importance and weight of each convenience evaluation indicator should be established through future research.

In this study, for the application of land resource evaluation using GIS map overlay method, I have considered about the process that can draw out right results from the problems involving multiple hierarchical indicators and weights. The assumption of this research is that there are two processes in the application of analytic hierarchy process(AHP) and the different results will appear. The two processes are as follows; (1) calculate directly the comprehensive weights to the indicators and overlay the layers(Method I) and (2) repeat the process of map overlay and standardization(Method II). The two precesses are applied on the study site based on the envirosystem in Bong-Hwa, and then some differences were found in the results and it was suggested that the Method II is more reasonable.

This study has begun with the perception that proper measuring system is required to grow community business in equilibrium and to grope for some developmental directions of it. First, for effective performance evaluation of community business, the study developed a performance evaluation model based on balanced score cards, and to apply validity analysis and analytic hierarchy process (AHP) by classifying. Second, the relative importance of the second indicator for each of the first aspects shows that participation of local residents and in the aspect of person interested, satisfaction of inner education in the aspect of learning and growth, shortening of work process in the aspect of inner process, and sales per head in the aspect of substantiality were high in relative importance. Third, in the result of calculation of overall weight for each aspect, participation of local residents, a business connection to the community, sales per head were ranked in the upper group. Thus, it's now necessary to have management support through fostering intermediate support organizations in community business which has been bureaucratic, and improvement of product and service through connection with outside consulting agencies and strategic alliance with the leading businesses is required.

This study examined the health status of female foreign spouses of multicultural families in Korea. More specifically, this study examined whether within-group difference exists depending on their country of origin in health status as well as determinants of their health status. For the analyses, data from the 2012 National Survey of Multicultural Families was used and a total of 165,451 spouses from China (both Korean-Chinese and Han Chinese), Vietnam, and The Philippines were included. The result showed that Vietnamese and Filipino women were healthier than Korean-Chinese and Han Chinese. The determinants and their size of the effect also varied across four groups of women. The results of this study highlight the importance of understanding immigrant women in the context of their ethnic background for interventions of their health. In addition, understanding their status and experiences in Korea must be in place for immigrant health studies, and potential differences by their country of origin must be considered in the development of health policies and practice.
