이 연구의 목적은 다양한 차원의 박탈지표를 이용하여 아동빈곤의 특성을 규명하는 것이다. 이 연구의 목적을 위해 2012년 7차 한국복지패널조사자료를 이용하였으며, 잠재집단 분석기법을 활용하여 아동빈곤 집단을 유형화하였다. 분석결과, 아동이 있는 가구를 주거비 과부담, 다차원 박탈, 비빈곤 등 세 개의 집단으로 유형화하였다. 주거비 과부담 집단은 다른 영역에서 박탈은 높지 않지만, 주거비 부담이 높은 집단이다. 다차원 박탈 집단은 열악한 주거환경, 식생활 영역 및 고용 등의 다양한 차원에서 박탈을 경험할 확률이 높은 집단이다. 마지막으로 비빈곤 집단은 박탈을 경험할 가능성이 매우 낮은 집단이다. 잠재집단의 특성을 파악하기 위해 다항로짓분석을 수행하였다. 분석결과, 다차원 박탈집단은 다른 두 집단과 차이가 있는 것으로 나타났다. 비빈곤 집단과 주거비 과부담 집단 간에는 큰 차이를 보이지 않는 것으로 나타났다. 분석결과는 아동이 거주하는 가구의 복지, 교육, 문화적 자원의 박탈 등 다차원적인 문제에 대한 통합적인 접근이 필요함을 시사한다.

In most cases of multidimensional scaling(MDS), the distances or dissimilarities among units are assumed to be symmetric. Thus, it is not an easy task to deal with asymmetric distances. Asymmetric MDS developed so far face difficulties in the interpretation of results. This study proposes a much simpler asymmetric MDS, that utilizes the notion of "altitude". The analogy arises in mountaineering: It is easier (more difficult) to move from the higher (lower) point to the lower (higher). The idea is formulated as a quantification problem, in which the disparity of distances is maximally related to the altitude difference. The proposed method is demonstrated in three examples, in which the altitudes are visualized by rainbow colors to ease the interpretability of users.

As social media draws attention as a business tool, organizations, large or small, are trying to exploit social media in their business. However, lack of understanding the characteristics of each social media led them to develop a naive strategy for dealing with social media. Thus, this study aims to deepen the understanding by comparatively analyzing how social media users perceive (the image of) each social media. Facebook, Twitter, YouTube, Blogs, Communities and Cyworld were chosen for our study and data from 132 respondents were analyzed using multidimensional scaling technique. The results show that there are meaningful differences in users' perception of social media attributes, which are grouped into four; information feature, motivation, promotion tool, usability. It is also analyzed whether such differences can be found between male and female users. (Such differences are also analyzed in both male and female users' perceptions.) Further, we discuss some implications of the research results for both practitioners and researchers.

This paper presents the ways that can improve the Software Cost Estimation Guidelines in order to replace those that are expected to be abolished at February, 2012, and solve the problems that are being occurred in the current Software Cost Estimation Guidelines. By using multidimensional modeling of OLAP(On-Line Analytical Processing), this paper does three dimensional modeling that considers the product/service view, process view and skill view. Also, it presents the identification method of cost estimation data through the view of each dimension. Furthermore, it defines the software cost estimation process and adapts them into the bottom up estimation and the top down estimation. Finally, it proposes the access of cost estimation data by the multidimensional analysis of OLAP.

A method and results of classification of 4 types metallic wear debris were presented by using their color features. The color image of wear debris was used (or the initial data, and the color properties of the debris were specified by HSI color model. Particle was characterized by a set of statistical features derived from the distribution of HSI color model components. The initial feature set was optimized by a principal component analysis, and multidimensional scaling procedure was used for the definition of classification plane. It was found that five features, which include mean values of H and S, median S, skewness of distribution of S and I, allow to distinguish copper based alloys, red and dark iron oxides and steel particles. In this work, a method of probabilistic decision-making of class label assignment was proposed, which was based on the analysis of debris-coordinates distribution in the classification plane. The obtained results demonstrated a good availability for the automated wear particle analysis.

개체들 사이의 관계를 저차원 공간에 매핑하는 다차원척도법을 수행하기 위한 다양한 방법과 알고리즘이 개발되어왔다. 그러나 PROXSCAL이나 ALSCAL과 같은 기존의 기법들은 50개 이상의 개체를 포함하는 데이터 집합을 대상으로 개체 간의 관계와 군집 구조를 시각화하는데 있어서 효과적이지 못한 것으로 나타났다. 이 연구에서 제안하는 군집 지향 척도법 CLUSCAL(CLUster-oriented SCALing)은 기존 방법과 달리 입력되는 데이터의 군집 구조를 고려하도록 고안되었다. 50명의 저자동시인용 데이터와 85개 단어의 동시출현 데이터에 대해서 적용해본 결과 제안한 CLUSCAL 기법은 군집 구조를 잘 식별할 수 있는 MDS 지도를 생성하는 유용한 기법임이 확인되었다.

The purpose of this study was to develop and validate a scale for the multidimensional assessment of work-family spillover in working couples with children. The subjects of this study were working wives and husbands with children in Daegu. Two surveys were administered, eliciting 243 respondents and 227 respondents, respectively. Then a series of tests were run to analyze the data, including item-to-total correlation, Cramer's V coefficients, item discrimination, Cronbach's ${\alpha}$, and exploratory and confirmatory factor analysis. The results yielded that, first, a preliminary 102 items were developed on the basis of the literature review, and this was narrowed down to 72 items selected with the help of experts. Through preliminary, primary and secondary survey analysis, the scale for the multidimensional assessment of work-family spillover was developed and validated, with a 36 items scale, 18 items for work to family spillover and 18 items for family to work spillover. Furthermore, the scale constructed three spillover processes - time interference, energy depletion, and psychological distraction - and consisted of four different domains of family life into which spillover occurs - namely marital relationship, parent-child relationship, leisure, and housework. The internal reliability was evaluated to show a confidence range of .85 ~.92 for each factor.

Today apparel finns make much effort to build a long-term relationship with their customers. The studies of salesperson-customer relationship emphasized the importance of customer's commitment on the formation of the continuous salesperson-consumer relationship. Therefore, the current study deals with the psychological relationship commitment development and from this prospective examines how consumers maintain the continuous relationship with a particular salesperson. The data were collected from January to February 2005 and analyzed by using SPSS 11.5 and Amos 5.0 with factor analysis, regression, ANOVA, path analysis. The results are as follows: First, the hypothetical model of multidimensional consumer commitment which showed a better fit of data than the rival model is unintentionally conceptualized. Second, the result showed that the affective commitment did the most effective role among the three dimensions of commitment consulted in this study. Especially the data indicated that for the establishment of the affective commitment in the salesperson-customer relationship. it is very important that a customer has deep trust in salesperson's ability, benevolence and honesty.
