본 연구에서는 감성분석기법이 환경평가에 적극 적용되어지면서 쓰이는 감성평가모형을 선행연구조사와 실험을 통해 두 가지 축약형 모형과 추론형 모형으로 구분하였다. 또한 두 가지 유형의 대표 모형인 EPA모형과 PAD모형의 평가어휘들의 특성을 실험을 통해 분석해 본 결과, 두 모형은 개발방식과 어휘구성에 큰 차이가 있고, 요인분석을 통해 어휘들이 모형별로 축약되는 것을 확인하였으며, 유사성 관계를 다차원척도법으로 분석한 결과 서로 관계성이 어느 정도 성립되는 것을 확인하였다. 이를 통해 감성평가모형이 감성평가에 사용될 때는 한쪽으로 치우치기 보다는 모형의 특징을 분석하여 적용하면 보다 객관적인 이미지 분석이 가능함을 알 수 있다. 본 연구에서는 가로경관 환경평가로만 국한되었다면, 다양한 분야에서의 평가대상이 비교될 수 있는 감성평가모형에 대한 지속적인 연구가 필요하다.

Purpose - In this paper, the degree of similarity and dissimilarity between pairs of 50 major cities in China can be shown on the basis of three evaluation variables(internet businessman index, internet shopping index and e-commerce development index). Dissimilarity distance matrix is used to analyze both similarity and dissimilarity between each fifty city in China by calculating dissimilarity as distance. Higher value signifies higher degree of dissimilarity between two cities. Cluster analysis is exploited to classify 50 cities into a number of different groups such that similar cities are placed in the same group. In addition, multidimensional scaling(MDS) technique can obtain visual representation for exploring the pattern of proximities among 50 major cities in China based on three development performance attributes. Research design, data, and methodology - This research is performed by the 2013 report provided with AliResearch in China(1/1/2013~11/30/2013) and utilized multivariate methods such as dissimilarity distance matrix, cluster analysis and MDS by using CLUSTER, KMEANS, PROXIMITIES and ALSCAL procedures in SPSS 21.0. Results - This research applies two types of cluster analysis and MDS on three development performances based on the 2013 report of Aliresearch. As a result, it is confirmed that grouping is possible by categorizing the types into four clusters which share similar characteristics. MDS is exploited to carry out positioning of both grouped locations of cluster and 50 major cities belonging to each cluster. Since all the values corresponding to Shenzhen, Guangzhou and Hangzhou(which belong to cluster 1 among 50 major cities) are very large, these cities are superior to other cities in all three evaluation attributes. Twelve cities(Beijing, ShangHai, Jinghua, ZhuHai, XiaMen, SuZhou, NanJing, DongWan, ZhangShan, JiaXing, NingBo and FoShan), which belong to cluster 3, are inferior to those of cluster 1 in terms of all three attributes, but they can be expected to be the next e-commerce revolution. The rest of major cities, in particular, which belong to cluster 4 are relatively inferior in all three attributes, so that this automatically evokes creative innovation, which leads to e-commerce development as a whole in China. In terms of internet businessman index, on the other hand, Tainan, Taizhong, and Gaoxiong(which belong to cluster 2) are situated superior to others. However, these three cities are inferior to others in an internet shopping index sense. The rest of major cities, in particular, which belong to cluster 4 are relatively inferior in all three evaluation attributes, so that this automatically evokes innovation and entrepreneurship, which leads to e-commerce development as a whole in China. Conclusions - This study suggests the implications to help e-governmental officers and companies make strategies in both Korea and China. This is expected to give some useful information in understanding the recent situation of e-commerce in China, by looking over development performances of 50 major cities. Therefore, we should develop marketing, branding and communication relevant to online Chinese consumers. One of these efforts will be incentives like loyalty points and coupons that can encourage consumers and building in-house logistics networks.

The purpose of this study was to explore socio-economic factors as determinants of food behavior and self-evaluation on meeting dietary guidelines. The data were derived from the KNHANES collected in 2007. A multidimensional framework of the determinants of food behavior was used, including age, gender, region, occupation, education, income and nutritional knowledge. The determinants of food behavior and self-evaluation were estimated by ordered logistic regression models. Food behavior was measured by dietary diversity scores including six food groups, which were cereals, vegetables, meats, fruits, milk, and oils. Self-evaluation on meeting dietary guidelines was based on responses from questionnaires for implementing Korean dietary guidelines. In general, the respondents who fulfilled all criteria were few. There were some differences between dietary diversity scores and self-evaluation on meeting dietary guidelines. Age, gender, and educational level showed effect on food behavior and self-evaluation. For dietary diversity scores, the individuals who were younger male, graduated from college were more likely to consume more various foods. The individuals who were older female, graduated from high school were more likely to meet dietary guidelines. Occupation was associated only with self-evaluation. Age and gender were associated with food behavior as well as self-evaluation. Income and marital status were associated only with dietary diversity scores. Reading food label and occupation were associated only with self-evaluation. The food behavior of married individuals was less in line with the dietary diversity scores than singles. In conclusion the differences between objective measure and subjective measure on individuals' diet showed more efforts like segmented nutritional education would be needed to increase the quality of dietary life.

The purpose of this study is to select and analyze words that represent various emotional states towards a spatial environment. Selecting appropriate words for the sensibility evaluation of a spatial environment is a process of constructing sensibility indicators, so that an accurate selection of sensibility words is very important. To collect basic words for this study, words for expressing sensation, emotional states, and sensibility regarding a spatial environment have been collected first via free association and a literature review of previous studies. In the second stage, the selected words are refined. Fifteen evaluators have participated in the first process of refining words, 140 college students participated in the second process, and than the final list of 277 refined words has been selected. During the third stage, 15 specialists were asked to evaluate the appropriateness of sensibility evaluation words, for that 7 point-scale has been applied. Then, 99 words with an average point of 4.55 or more and a standard deviation of 1.55 or lower were selected. After investigating the similarity in the meanings of the selected words, 55 pairs of contrasting words have been selected as a final list of sensibility evaluation words. During this last stage, 307 college students majoring in related fields were asked to evaluate the appropriateness of sensibility evaluation words for a spatial environment, and 7 point-scale was obtained. A factor analysis, cluster analysis, and multidimensional analysis have been conducted on the data obtained from these survey. According to the results of the factor analysis, the eight important factors are obtained from the sensibility evaluation criteria of a spatial environment(form, texture, function, value, comfort, aesthetics, atmosphere, and affinity). The factors obtained from this study can be used in the beginning stage of evaluating the sensibility factors of a spatial environment. In addition, the results of this study can be used as basic data when constructing a list of evaluation indicators to select various complex sensibility words for a space; or as general indicators when evaluating various spatial design factors.

The prototype generation IV sodium-cooled fast reactor (PGSFR) has been developed by the Korea Atomic Energy Research Institute. This reactor uses sodium as a reactor coolant to transfer the core heat energy to the turbine. Sodium has chemical characteristics that allow it to violently react with materials such as a water or steam. When a sodium-water reaction (SWR) occurs due to leakage or breakage of steam generator tubes, high-pressure waves and corrosive reaction products are produced, which threaten the structural integrity of the components of the intermediate heat-transfer system (IHTS) and the safety of the primary heat-transfer system (PHTS). In the PGSFR, SWR events are included in the design-basis event. This event should be analyzed from the viewpoint of the integrities of the IHTS and fuel rods. To evaluate the integrity of the IHTS based on the consequences of the SWR, the behaviors of the generated high-pressure waves are analyzed at the major positions of a failed IHTS loop using a sodium-water advanced analysis method-II code. The integrity of the fuel rods must be consistently maintained below the safety acceptance criteria to avoid the consequences of the SWR. The integrity of the PHTS is evaluated using the multidimensional analysis of reactor safety-liquid metal reactor code to model the whole plant.

OLAP(On-Line Analytical Processing) 툴은 조직 운영에서 발생하는 데이터의 양이 많아짐에 따라 분석 수요도 함께 급증하며 전문 분석가의 역량만으로는 처리할 수 없는 분석 요구 사항을 충족시키기 위한 툴이다. OLAP에서는 다양한 사용자가 직접 데이터베이스에 접근하여 대화식으로 질의를 던지고 응답을 받아 분석 업무를 진행할 수 있다. 이렇게 많은 사용자들이 데이터베이스에 직접 접근을 하게 됨에 따라 조직의 민감한 데이터를 지키기 위한 보안 정책이 필수가 되었다. 하지만 기존 연구에서는 OLAP의 기능적인 분석에 치중하여 MDX(Multidimensional Expressions)와 XMLA(XML for Analysis) 등의 기법으로 기능을 구현하는 것에 그치고 있다. 이에 본 연구에서는 기존 연구의 문제점을 보완하기 위한 방법으로 효율적인 정보 보호를 위한 데이터 접근 제어 메커니즘을 제안하고 이를 설계 및 구현하였다. 제안한 데이터 접근 방법이 실제 OLAP 환경에서 효율성 있게 동작함을 확인하기 위해 실험평가를 수행하여 본 연구의 우수성을 입증하였다.

This study analyzed the outcomes of the Healthy Family Support Center's 2011 Pilot Project to support grandparent-grandchild families. This paper applied Frank Fisher's multidimensional evaluation methodology, which includes 4 steps: program verification, situational validation, system vindication and social choice. The major findings and their implications are as follows: the strong points of the pilot project are the characteristics of its services, i.e. sending services, customized services, family-unit services and integrated services. Therefore, it is necessary to train human resources to deliver these services more professionally and to provide comprehensive life-planning. The weak point of the pilot project is its lack of services relating to the self-reliance of the clients. Thus it is necessary to revise the service subsystems to include programs that promote self-support measures.
