  • 본 연구는 청소년을 대상으로 하여 분노표현의 하위차원인 분노조절, 분노억제 및 분노표출 방식 별로 군집 양상을 구분하고, 간 군집 별로 우울과 공격성, 부정정서강도에 있어서 어떠한 차이가 나타나는지 살펴보고자 하였다. 이를 위해 남녀 중학생을 대상으로 설문조사를 진행하고 총 296명의 자료를 분석하였다. 연구 결과, 첫째, 분노조절, 분노억제 및 분노표출에 대한 군집분석 결과, 네 개의 프로파일 군집이 추출되었다. 군집 1은 '억제 및 표출형 분노조절형', 군집 2는 '분노억제 및 표출형', 군집 3은 '분노처리 미숙형', 군집 4는 '표출적 분노조절형'으로 구분되었다. 둘째, 이러한 네 개의 군집 별로 우울과 공격성, 부정정서 강도의 차이가 유의하게 나타났다. 즉, 군집 4인 '표출적 분노조절형'이 다른 군집들에 비해 유의하게 더 높은 우울감을 나타내었고, 군집 3인 '분노처리 미숙형'은 다른 군집들보다 더 큰 공격성을 나타내었다. 한편, 군집 2인 '분노억제 및 표출형'이 군집 4인 '표출적 분노조절형'보다 부정정서강도가 더 높았다. 이러한 결과를 통해, 청소년 교육 및 상담을 통한 시사점에 대해 논의하였다.

  • We consider zero range processes with density dependent jump rates g given by $g=g(n,k)=g_1(n)g_2(k/n)$ with $g_1(x)=x^{-\alpha}$ and $$g_2(x)=\{^{x^{-\alpha}\;if\;a&lt;x}_{Mx^{-\alpha}\;if\;x{\leq}a}$$. (0.1) In this case, with 1/2 < a < 1 and ${\alpha}$ > 0, we show that non-complete condensation occurs with maximum cluster size an. More precisely, for any ${\epsilon}$ > 0, there exists $M^*$ > 0 such that, for any 0 < M ${\leq}M^*$, the maximum cluster size is between (a - ${\epsilon}$)n and (a + ${\epsilon}$)n for large n. This provides a simple example of non-complete condensation under perturbation of rates which are deep in the range of perfect condensation (e.g. ${\alpha}$ >> 1) and supports the instability of the condensation transition.

  • Zn-resistant Methylosobacterium strains were isolated from several non-polluted soil samples collected in all over Japan. Zn-resistant Methylosobacterium strains were predominantly detected in all soil samples and they were also characterized as a UV-tolerant bacteria. The MIC test revealed that the isolates have high zinc resistance in comparison with that of reference Methylosobacterium strains obtained from culture collections. The 16S rDNA-based phylogenetic analysis showed that all strains were divided into two clusters designated as cluster A and cluster B in the present study. All isolates were distributed only in the cluster A. The phylogenetic clustering also well coincided with the differences in the pattern of carbon source utilization.

  • The increasing late-payment rate of credit card customers caused by a recent economic downturn are incurring not only reduced profit of department stores but also significant loss. Under this pressure, the objective of credit forecasting is extended from presumption of good or bad customers to contribution to revenue growth. As a method of managing defaults of department store credit card, this study classifies credit delinquents into some clusters, analyzes repaying patterns of customers in each cluster, and develops credit forecasting system to manage delinquents of department store credit card using data of Korean D department store's delinquents. The model presented by this study uses Kohonen network, a kind of artificial neural network of data mining techniques to cluster credit delinquents into groups. Logistic regression model is also used to predict repayment rate of customers of each cluster per period. The accuracy of presented system for the whole clusters is 92.3%.

  • In this study, we developed a heuristic algorithm to get better efficiency of clustering than conventional algorithms. Conventional clustering algorithm had lower efficiency of clustering as there were no solid method for selecting initial center of cluster and as they had difficulty in search solution for clustering. EMC(Expanded Moving Center) heuristic algorithm was suggested to clear the problem of low efficiency in clustering. We developed algorithm to select initial center of cluster and search solution systematically in clustering. Experiments of clustering are performed to evaluate performance of EMC heuristic algorithm. Squared-error of EMC heuristic algorithm showed better performance for real case study and improved greatly with increase of cluster number than the other ones.

  • In this study, the representative hand shapes for the adult Koreans were analyzed by factor analysis and cluster analyses. The analyses were conducted on the anthropometric data of 58 hand dimensions from 325 subjects having nonhomogeneous demographics. Maximum hand circumference, first phalanx length of index finger, and ratio between the two measures were the independent variables for the cluster analyses. The results of the study showed that Korean hand shapes can be divided into 2 clusters irrespective of their size for each of the male and female group. There were slight differences in component ratio of hand shapes with respect to the occupation and the age, but their differences were not statistically significant. The representative Korean hand shapes and their anthrpometric dimensions could be used to design and establish proper sizing system for various hand operating devices.

  • The aim of this paper is to identify Korean agricultural and agri-manufacturing cluster using a multi-regional input-output model. This paper derives a representative set of five agricultural and agri-manufacturing clusters in Korea in terms of spatial and industrial interdependency. The results show that agriculture and agri-manufacturing clusters agglomerated in Seoul Metropolitan Area and Chungcheong Area are linked both production and manufacture functions, whereas Gangwon Area is more focused on production and Jeolla Area is more concentrated on manufacture.

  • 본 연구는 중소기업의 기술혁신에 있어 중요하면서 실증연구가 부족한 산업클러스터의 체계성과 기업가 정신, 그리고 기술혁신 과정의 체계성을 위해 반드시 고려되어야 할 R&D역량이 기술혁신과 어떤 관계를 가지는지 실증하였다. 대구지역 중소기업을 대상으로 분석한 결과, 산업클러스터의 산업생산체계는 기업가정신에 긍정적인 영향을 미쳤으며, 기업가정신은 기술혁신에 긍정적인 영향을 미쳤다. 산업클러스터의 과학기술체계는 R&D역량과 기술혁신에 긍정적인 영향을 미쳤으며, R&D역량도 기술혁신에 긍정적인 영향을 미쳤다. 반면 산업클러스터의 기업지원체계는 어디에도 영향을 미치는 않는 것으로 나타났다. 본 연구의 결과는 중소기업의 기술혁신 과정에 대한 이해와 산업클러스터 정책 수립의 뒷받침 자료가 될 것이다.

  • This study suggests a Causal Loop Diagram(CLD) of causality mechanism which are integrating matters of localization, networking, embeddedness & institutional thickness and collective learning. These five factors(localization, networking, embeddedness & institutional thickness, collective learning, innovative synergy) have been studied and proofed Also this study suggest a model of industry cluster based on holistic and global system thinking rather than local and linear thinking.
