  • In recent, the Korean fisheries industry face an overall crisis. Annual fish catch is continuously decreasing for last two decades even though various programs to improve fish population. Moreover, domestic fish market is more and more occupied by imported cheap fish products from abroad due to the consequence of open economic policy, FTA and WTO/DDA entente. Under the circumstances, this study aims to examine the potential for building fisheries cluster as a policy tool to promote fisheries and fisheries-associated industries in Korea. To achieve this goal, the authors firstly reviewed the theoretical concept of Industrial Cluster in the evolutionary economics point of view, secondly, analyzed the main components of Porterian Cluster(or innovation cluster), thirdly, derived the key reasons to induce the improvement of productivity within the cluster network system and lastly evaluated fisheries capability and industrial infrastructures of each province as a basic condition to build a fisheries cluster. The result of the study demonstrates the voluntary accumulation of fish products and processing techniques in Korea, however, it is not enough to make up a Porterian innovation. Therefore, the present is most opportune for applying fisheries cluster as a strategic policy tool. Government supports to establish innovation cluster for fisheries may contribute both fisheries industry and local economy by developing the latent capacity of fisheries and helping concentrate innovation capabilities.

  • The crystallization behavior of the amorphous $Fe_{73.5}Cu_{1}Nb_{3}Si_{16.5}B_{6}$ alloy with isothermal annealing at $552^{\circ}C$ was studied by $M\"{o}ssbauer$ spectroscopy. The amorphous phase was revealed to coexist together with $Do_{3}-FeSi$ nanocrystalline and Cu-duster in annealed alloys by $M\"{o}ssbauer$ spectrum analysis. At the early stage of crystallization, Si content of FeSi is high due to the creation of Cu-cluster, and decreases with annealing until 60 minutes, which results in the increase in the mean hyperfine field of FeSi, and thereafter keeps constant. After 60 minutes, the decrease in the mean hyperfine field of the residual armrphous, in spite of a slight change in the volume fraction of the FeSi and the residual armrphous, is caused by the increase in the content of Nb and B in residual amorphous phase. Both directions of the hyperfine field, those of the FeSi and the residual amorphous, become randomly oriented in about 60 minutes. For FeSi and Cu-duster, the Avrami exponents are 0.51 and O.65, the activation energies are 2.35 eV and 2.44 eV, and the incubation times are 2.4 minutes and 0.8 minutes respectively. Earlier formation of Cu-duster than that of FeSi is coincidence with the fact that Cu atom promotes the nucleation of the FeSi.

  • The effective construction for ready-made clothes is one of the central concerns of both consumer and manufactures in today's apparel industry. So in order to reduce the burden of stocks and increase clothing fitness, systematic information on typical body size and somatotypes is essential. This study was performed to provide fundamental data on junior-high school girls' somatotype by classifying the lower body somatotype and analyzing the characteristics of each somatotype. The subject were 236 Korean junior-high school girls. The subject were directly measured anthropometrically and indirectly analyzed photographically. By direct measurement, 5 factors were extracted through factor analysis and the subject were classified into 4 duster as their lower body front silhouette. By indirect measurement, 5 factors ore extracted through factor analysis and the subject were classified into 3 cluster as their lower body side silhouette. After combining the body types of the front and the side silhouette, we selected 4 basic body types out of combination.

  • This paper investigated the influence on partial discharge distribution of various defects at the model power cable joints interface using K-means clustering. As the result of analyzing discharge number distribution of ${\Phi}-n$ cluster, clusters shifted to $0^{\circ}\;and\;180^{\circ}$ with increasing applying voltage. It was confirmed that discharge quantity and euclidean distance between centroids were increased with applying voltage from the analyzing centroid distribution of ${\Phi}-q$ cluster. The degree of dispersion was increased with calculating standard deviation of ${\Phi}-q$ cluster centroid. The tendency both number of discharge and mean value of ${\Phi}-q$ cluster centroid were some different with defect types.

  • This study is to estimate the factor weights of the reasons for decreases in marine fishery resources using the Analytical Hierarchy Process. Furthermore, it classifies 20 fishes under a fishery resource recovery plan into various groups of fishes according to these factor weights using the non-hierarchial cluster analysis. The factors of decreases in marine fishery resources are identified as bio-ecological, technology-system, economic-business, and fishing village-society factors. Two of the most important factors of decreases in resource are turned out to be the economic-business and bio-ecological factors, estimated as 31% and 30% respectively. The technology-system and fishing village-society factors are estimated as 21% and 18% respectively. The study utilizes non-hierarchical cluster analysis in order to classify 20 fishes into 2, 3, and 4 groups. K-means cluster analysis is applied for grouping in conjunction with ANOVA to identify statistical differences in factors. Once again, the economic-business and bio-economic factors play main role in grouping 2-groups of fishes case. The third group of fishes in addition to the previous 2 groups of fishes appears as those 4 factors of decrease evenly play about the same role at a 3-groups of fishes case. Finally, the economic-business and bio-economic factors are turned out to be evenly important in the 4th group once there are 4-groups of fishes.

  • The purpose this study is to segments apparel market based on difference real-self image and ideal-self image. The objects of the study were to prepare for the establishment of marketing strategy and alternative plan intended to users which are needed in subdivided market, after analyzing according to what the subdivided market is divided into due to the difference real-self image and idea-self image and what difference do they show as a demographic special quality or as a general active special quality in each subdivided market. Factor analysis was performed to determine the leading difference real-self image and ideal-self image, and cluster analysis was employed to identify groups of respondents based on the delineated five image difference factors. Based on the finding, three distinct groups were formed: ideal-self image seeker group, moderators group, real-self image seeker group. And logistic regression was used to assess the relative importance that demographic characteristics play in determining the segmentation. The results of this study show statistically significant differences among the three groups in terms of demographic. Marketing and management implications for effectively targeting the segments are discussed.

  • This article presents the results of a survey of 209 Chinese male consumers. In this study, consumer evaluations and attitude towards products made in industrialized and newly industrialized countries were obtained along with measures of consumer shopping behavior. The results indicate that industrialized countries were perceived as manufacturing products that are more reliable, technologically advanced, stylistic, and costly than newly industrialized countries. A duster analysis using moderating variables related to shopping for refrigerators, cameras, and t shirts revealed that the Chinese respondents could be grouped into four segments identified as Durables Enthusiasts, Duraoles Uninvolved, Inexperienced Shoppers, and Apparels Involved. Country attitudes and evaluations were fairly consistent across the newly industrialized countries but varied for industrialized countries across the four segments. Similar results also emerged from a correlation analysis of made in attitude scales (based on moderating shopping variables) with country evaluations. It was found that Chinese consumers' involvement with durable products was positively related to the evaluation of industrialized countries. Consumers belonging to the Durable Enthusiasts and Apparels Involved segments evaluated industrialized countries more favorably and believed to a greater extent that products made in these countries are reliable, technologically advanced, and stylistic than consumers belonging to the Durables Uninvolved and Inexperienced Shopper segments. Managerial and research implications are derived from these results.

  • The purposes of this study were to examine the attitude of undergraduates toward money and the differences in dining-out behavior among three groups of subjects divided by attitude toward money. Self-administrated questionnaires were completed by 387 undergraduates and data were analysed by frequency analysis, chi-square, t-test, one-way ANOVA, factor analysis, reliability analysis, duster analysis and discriminant analysis. Results of study were as follows. There appeared six different attitudes of money among the undergraduates investigated: money as a means of seizing power, money as a life pursuit, money as a tool for rational consumption, money as a barometer of success, money as a cause of anxiety, and distrust. The undergraduates showed several different attitudes of money according to gender, major, age and pocket money. Cluster analysis divided subjects into three groups by attitude toward money : low dependent group, moderately dependent group and high dependent group. Three groups of subjects classified by attitudes of money were different from one another in dining-out behavior as well. The low money-dependent group mainly spent less than 5,000 won on a dining-out, and relied on their own experience and recommendation from others on a dining-out information. In contrast, the high money-dependent group spent 20,000 won or more on dining-out, and the distribution of subjects acquiring dining-out information from various channels in that group was significantly higher than other groups.
