Recent development in science and technology has modernized the weapon system of ROKN (Republic Of Korea Navy). Although the cost of purchasing, operating and maintaining the cutting-edge weapon systems has been increased significantly, the national defense expenditure is under a tight budget constraint. In order to maintain the availability of ships with low cost, we need accurate demand forecasts for spare parts. We attempted to find consumption pattern using data mining techniques. First we gathered a large amount of component consumption data through the DELIIS (Defense Logistics Intergrated Information System). Through data collection, we obtained 42 variables such as annual consumption quantity, ASL selection quantity, order-relase ratio. The objective variable is the quantity of spare parts purchased in f-year and MSE (Mean squared error) is used as the predictive power measure. To construct an optimal demand forecasting model, regression tree model, randomforest model, neural network model, and linear regression model were used as data mining techniques. The open software R was used for model construction. The results show that randomforest model is the best value of MSE. The important variables utilized in all models are consumption quantity, ASL selection quantity and order-release rate. The data related to the demand forecast of spare parts in the DELIIS was collected and the demand for the spare parts was estimated by using the data mining technique. Our approach shows improved performance in demand forecasting with higher accuracy then previous work. Also data mining can be used to identify variables that are related to demand forecasting.

Women are playing an increasing role in the society amid the increase in the age at first marriage, reduced family size, and the weakening solidarity among family members. Gold Miss is a newly coined word which reflects the change in the value of women in the wake of the individualism and pluralism amid the structural change. Gold Miss means a new X generation that is sensitive to the latest fashion and trend with high purchasing power and self-attainment goal. They do not spare any effort to invest in themselves, lead the new culture and set the cultural trend that goes beyond the simple consumption, and come into the spotlight both socially and economically. The outcome of the analysis on the Gold Miss fashion which was revealed in the mass media indicated that the fashion was the instrument to express their own images and personalities. Though they may be some difference depending on the occupation, personality, values, and others, they pursue sophisticated, intellectual, and emotional office-look that takes the trend and personality into account. In addition, they prefer business casual attire, and pursue the total fashion with perfection which uses the gorgeous bright and vivid color, daring color, accent color arrangement and accessories. The Gold Miss fashion implies the self-identity, high-end feature, and embody the symbolism of information, which the analysis on the feature and fashion of Golden Miss indicated.

PC기반의 인터넷에서 모바일로 플랫폼의 변화가 일어난 후 SNS가 대면 교류를 대체하는 새로운 대화 매체로 자리를 잡았다. 사용자들은 이미 SNS를 생필품으로 인식하기 시작했으며 나아가 SNS시장은 세분화 되고 있다. 즉, 특정 대상과 컨텐츠에 집중한 수직적(Vertical) SNS의 시대로 접어들었다고 볼 수 있다. 따라서 SNS기획에서 명확한 사용자 분석이 필요하며 이러한 시점에서 가장 구매력이 있는 직장인들이 SNS사용 이유를 살펴보는 것은 SNS사업자 입장에서는 의미가 있다. 이에 본 연구에서는 'SNS사용과 자기표현 및 사회적 지지와 직장인의 스트레스와의 관계'를 살펴봄으로써 직장인의 SNS사용 이유를 분석하였다. 그 결과 SNS 사용은 자기표현 및 사회적 지지와 관련 있었다. SNS에서의 자기표현은 직장인의 특성상 스트레스와 관련이 없었으나 SNS에서의 사회적 지지는 스트레스에 영향을 미치는 것을 확인하였다.
