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.

기존의 ad-hoc 라우팅 프로토콜 성능분석은 ad-hoc을 구성하는 모든 노드들이 독립 이동하는 모델을 중심으로 주로 수행되었다. 그러나 실제 상황에서는 노드가 임의로 독립 이동을 하기보다는 단일 그룹 또는 몇 개의 그룹을 구성하여 이동하며 각 그룹에 리더가 존재하는 경우가 자주 발생하게 된다. 본 논문은 그룹의 리더가 존재하는 그룹 이동 환경에서의 ad-hoc 라우팅 프로토콜의 성능분석을 수행하여 새로운 결과를 제시하였다. 군 전술 이동 망 등에 적합한 그룹 이동 모델인 RPGM 환경에서의 테이블 기반 DSDV 프로토콜과 요구 기반 AODV와 DSR 프로토콜 성능을 비교 분석 하였다. 단일 그룰 외에 다수 그룹의 이동도 함께 연구 제시하여 그룹 이동에 따른 특성 분석을 보다 포괄적으로 수행하고자 하였다. 단일 그룹 환경에서의 일반적인 성능특성은 노드 그룹 이동의 환경에서도 노드 독립 이동과 거의 유사함을 보였다. 그러나 독립이동의 경우 pause time이 증가함에 따라 높은 전송률을 보인 반면, 그룹이동 환경에서는 변함이 거의 없었다. 또한 연결 비율을 증가시키는 경우 기존 독립 이동시에는 전송지연시간이 일정하게 유지되나, 다수 그룹 이동의 경우 요구 기반 프로토콜 사용 시 감소하였다.

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.

소셜 네트워크 연구는 단일노드와 링크에 초점이 맞추어져 있다. 하지만, 소셜 네트워크의 복잡성을 고려할 때, 특정조건을 만족하는 여러 노드에 의한 종합적인 영향을 분석하는 것이 필요하고 생각한다. 하지만, 서브 네트워크 외에는 연구가 진행되고 있지 않다. 본 논문은 여러 노드에 의한 영향 분석에 중점을 두고 있다. 이를 위하여 특정 조건을 만족하는 복수개의 노드로 구성된 그룹노드 용어를 정의한다. 그리고 그룹노드를 적용하여 소셜 네트워크를 새롭게 구성하는 방법을 제시한다. 그리고 특정 조건에 맞는 그룹노드를 구성하는 프로그램을 유전자 알고리즘을 활용하여 제작하고, 결과를 제시하였다. 본 연구가 그룹노드를 기반으로 하는 소셜 네트워크 분석의 시발점이 되기를 바란다.

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.
