The purpose of this study was to analyze high school students' school uniform wearing attitude by group according to clothing attitude targeting Gyeongnam area. This study aims to provide preliminary data in the field of school uniform and marketing that clothing propensity by groups is considered. This study conducted a survey targeting 762 high school students in Gyeongnam. For statistical analysis, SPSS for Window 14.0 was used for frequency analysis, factor analysis, reliability analysis, multiple sponse analysis, cluster analysis, ANOVA analysis and Duncan's ex-post analysis method. As a result of cluster analysis on the clothing attitude, students were divided into 4 segmentation of fashion seeking group, fashion indifference group, conformity group and modesty group. As a result of verification on the difference in perception toward wearing school uniform by groups which were classified according to the propensity of clothing attitude, activity, stability, and practicality were all varied according to the propensity of clothing attitude. 4 groups were significant differences in the degree of consent to wearing school uniform, price of school uniforms, tendency to prefer famous brand when purchasing school uniform, experience of transforming school uniform, opinion about school uniform modification and reason for school uniform modification. While low graders were many in 'modesty group', upper graders were many in 'fashion seeking group', which means that more segmentalized satisfaction of clothing by group may be raised if such a fact is considered when planning clothing for high school students segmentalized by age.

Most pier performance analysis results for ad-hoc routing protocols have been based upon the model which each node in the network moves independently without restriction. In most real environments, however, it is very common for a group or multiple groups to move under the direction of group leader or group leaders instead of each node's independent movement. This paper presents the performance analysis of routing protocols for mobile ad-hoc network under group mobility environment. The comparative simulations have been made between a table-driven protocol, DSDV, and two on-demand protocols, AODV and DSR, under a group mobility model, RPGM, which is suitable for the practical applications such as military tactical operation. Multiple group movements are also included. The results show that the protocol performances for single group movement are very similar to node independent movement case. However some differences have been observed by varying pause time and connectivity.

The purpose of this study was to examine family factors affecting compulsive buying behavior. Three hundred fifty-five female college students who had purchased fashion products through Internet shopping or TV home shopping participated in this study. For data analysis, descriptive statistics, correlation analysis, t-test, multiple regression, and reliability test. As the results, approximately 18% of respondents were revealed as compulsive buyers. Compulsive consumption scores were correlated to higher previous childhood consumption experience, family matters, parents' compulsive consumption tendency, and reference group. Also, results of multiple regression revealed that previous childhood consumption experience, parents' compulsive consumption tendency, and reference group were significantly related to compulsive buying, Finally, there were significantly differences between compulsive buyers and non-compulsive buyers on previous childhood consumption experiences, parents' compulsive consumption tendency, and reference group. Based on these results, this study would provide significant implications to academic scholars, consumer policy decision makers, and marketers.

We investigate the latent stage-sequential patterns of drinking behaviors of U.S. adolescents who have started to drink by age 14 years (seven years before the legal drinking age). A multiple-group latent transition analysis(LTA) with logistic regression is employed to identify the subsequent patterns of drinking behaviors among early-onset drinkers. A sample of 1407 early-onset adolescents from the National Longitudinal Survey of Youth(NLSY97) is analyzed using maximum-likelihood estimation. The analysis demonstrates that early-onset adolescents' drinking behaviors can be represented by four latent classes and their prevalence and transition are influenced by demographic factors of gender, age, and race.

The purpose of this study was to verify potential differences in group- specific external feature concerns and beauty care behaviors of Korean women in their 20's~40's depending on their narcissistic propensity. This study is to take psychological approaches to narcissistic propensity of our contemporary society, so that it can get better understanding about consumers and provide marketing data on beauty-related industry. To meet the above goals, total 400 sheets of questionnaire were distributed to subjects from March 30 to April 8, 2009. Out of 376 sheets of questionnaire collected, total 355 valid questionnaires except incomplete 21 ones were used for final data analysis. For data analysis, this study used SPSS 12.0 as statistic program to perform factor analysis, reliability test (Cronbac's ${\alpha}$ coefficient), cluster analysis, t-test, analysis of variance (ANOVA), Duncan's multiple range test and multiple regression analysis. As a result, this study could come to the following findings: First, according to cluster analysis depending upon different factors such as self-directed narcissism, others-conscious narcissism and others-sensitive narcissism, it was found that our women in 20's to 40's could fall into 4 groups, i.e. complex narcissism group, mixed narcissism group, others-sensitive narcissism group and dispirited narcissism group. Second, according to analysis on potential differences in external feature concerns among four groups depending on their narcissistic propensity, it was found that there were significant differences in all relevant factors among groups. Third, according to analysis on differences in beauty care behaviors among four groups depending upon their narcissistic propensity, it was found that there were significant differences in all relevant factors among groups. Fourth, according to analysis on potential factors of external feature concerns that may influence beauty care behaviors of complex narcissism group, it was found that those factors had significant effects on fashion-orientedness, cosmetic surgery and personality pursuit of this group. And it was also found that there were significant differences in fashion-orientedness, cosmetic surgery, makeup and hair styling of mixed narcissism group, others-sensitive narcissism group and dispirited narcissism group respectively.

A research of Social Network is focused to the single node and link. But when we consider the complexity of Social Network, I think we need the analysis of integrated influence by multiple nodes that satisfied with specific condition. But, the study of this area don't process apart from Sub-network concept. The purpose of this paper is to focus on the analysis of influence by multiple nodes. For it, I define a new term as Group Node, and it express multiple nodes that satisfied a specific condition. And I propose a method for reconstruction by using Group Node in Social Network. and I make a program that produce a Group Node satisfied with a special condition by using Genetic Algorithm, and show the result. I hope this result can be a start point of the Social Network analysis based on Group Node.

This study intends to examine the effect of research and development (R&D) expenditure effects on firm value through patent and earing persistence. The patent is the representative intangible asset which objectively indicates a typical product of research and development activities to external parties. If a firm has acquired the patent, it receives amicable evaluation from the market compared to the firm which has not acquired patent. Empirical analysis is performed for non-banking firms (1,860 firm-years) listed on Korean Stock Exchange with December fiscal year-end over 2004-2009. Research results are as follows. First, the multiple pricing of patent acquiring firm and earing persistence increased group showed that they have higher prices than the other groups. Second, the multiple pricing of R&D expenditures of earing persistence increased group showed that they have higher prices than the other group. Third, the R&D expenditures of earing persistence increased group is receiving more friendly evaluation from the stock market than the other group.

This paper constructs Croup Technology process-based learning curve model adjusted to a Group Technology environment which accounts for shared learning that occurs when multiple products utilize some of the same process steps. Through this constructed model, the estimated times and productivity of labor calculated by the Group Technology process-based learning curve model are compared with those generated by employing product-based 1 earning curve model. For sensitivity analysis of the model, the impact of learning rate and the ordered production quantity on the ratio differences between Group Technology process-based learning curve model and product-based learning curve model are examined. These results indicate the critical importance of employing Group Technology process-based learning curve model when a process spans multiple products.

The purpose of this study was to investigate the effects of sociocultural attitudes toward appearance on male consumers' apparel buying behavior and appearance management behavior. The subjects were 353 males aged from 40 to 59 years old. The research method was a survey and the questionnaire consisted of sociocultural attitude toward appearance items, apparel buying behaviors items, appearance management behaviors items, and subjects' demographic characteristics items. The data were analyzed by Cronbach's ${\alpha}$, factor analysis, cluster analysis, multiple response analysis, ${\chi}2$ test, ANOVA and Duncan's multiple range test. The results were as follows. Three dimensions (appearance importance awareness, slimness importance awareness, internalization) were emerged on sociocultural attitude toward appearance, and subjects were divided into 4 groups(receptive, unreceptive, awareness, and internalized group) by this variable. The 4 groups by sociocultural attitude toward appearance showed many differences on apparel buying behaviors and appearance management behaviors. Receptive and internalized group more importantly regarded fashion trend and store display as apparel buying motives, design and trend as selection criteria, and did shopping to buy clothes more often than awareness and unreceptive group. Receptive and internalized group recognized higher the need for various appearance management behaviors and spent more expense to enhance their appearance than other groups.
