The purpose of this study was to classify male consumer groups according to the fashion lifestyle, to examine characteristics, needs and wants of each group, and to find out differences of cosmetics purchasing behavior among each group segment. After surveying 19-50 year old males by making a visit to college, company and home, 584 samples were analyzed by using SPSS(7.0) package program. Factor analysis, cluster analysis, ANOVA, crosstabs and $X^2-test$ were used to analyse collected data. The results of this study were as follows; 1. Twenty-two questionnaires using AIO fashion lifestyle variables produced seven factors; oriented fashion, flaunting brand preference, active preference, information intention, strong personality, reasonable economy and others directivity. Three groups based on oriented seven factors: personality, fashion and economy. 2. The Personality group had strong personal characters in their fashion. Men in this group prefer casual style and were represented by singles and professionals in their 30's. The fashion group pursued fashion trends, formal wears, and high-priced fashions. They were represented by singles with high-income managerial positions in their 19-29 age group. The economy group represented the largest sample in this study(54.5%). Men in this group tended to purchase fashion goods during of good fabrics at discount stores. This group represented married man with average incomes in their 40's. 3. Each of these three groups showed significant differences in cosmetics purchasing behavior. The personality group mainly purchased cosmetics on-line market because of price. The Internet tended to be their primary source of informations. They spent under 10,000won and pursued a simple and clear image. The fashion group purchased cosmetics at department stores to benefit from the knowledge of sales personal and their source of informations in the mass media. They spent over 70,000won monthly and pursued also a simple and clear image. The economy group purchased cosmetics at discount stores because of their wide assortment of products. They spent under 30,000won monthly and pursued a simple and clear image. Each of these groups currently consume different products and have a different concept of future cosmetic products.

최근 도심지 고층 구조물의 수가 증가하면서 수명이 오래된 구조물에 대한 재건축 수요가 증가하고 있는 실정이다. 기존 구조물을 철거하는 방법에는 기계식 해체 공법과 발파 해체공법이 있으나 10여층 이상의 고층건물일 경우 발파해체공법을 사용하는 겅이 경제적으로 유리한 것으로 알려져 있다. 발파해체공법을 사용할 경우, 발파에 앞서 미리 그 붕괴거동을 예측하는 일은 안전한 발파를 위해서 뿐만 아니라 발파해체의 실패를 방지하기 위해서 필수적으로 요구된다. 과거의 연구에서 이차원 입자결합모델을 사용하여 구조물 해체과정을 모사한 사례가 있었지만, 실제 발파붕괴 거동을 적절히 모사하는 데는 많은 제약이 있었다. 본 연구에서는 개별요소법을 기반으로 입자결합모델을 사용한 상용 프로그램인 PFC3D를 사용하여 구조물의 3차원 해체발파를 모사하였다. 삼차원 해석에서는 해석 시간이 오래 걸리는 단점으로 인하여 현실에 가까운 모사를 완성할 수 없었지만 몇 가지 입력변수를 바꾸어가며 그들의 효과를 관찰하였다. 보다 현실에 가까운 결과를 얻기 위해서는 입력변수의 설정과 부재 특성의 모사에 보다 많은 노력이 필요할 것으로 보인다.

The purpose of this study was to find discover the effects of self-efficacy and self-esteem on the appearance management behavior of female college students. As for the study method, questionnaire survey sheets on general traits like age, grade year, major and management cost, sense of self-efficacy, self-esteem, and appearance management behavior were distributed to female college students. The responses were measured based on a 5-points Likert scale. The results of this study are as follow: One's sense of social self-efficacy and self-esteem were both found to affect appearance management behavior significantly. In other words, the greater one's sense of social self-efficacy, which represents one's sense of confidence in inter-personal relations, the greater one's appearance management behaviors to enhance her own value. Furthermore, the greater one's self-esteem(the way one feels positively about oneself), the greater one's appearance management behaviors. As a result, it can be judged that the more an individual wants to act more capable in different contexts, the more she tries to make up for her own disadvantage. To highlight her own advantages for the sake of greater positive social activities and inter-personal relation, the more she takes to improve her image through appearance management behaviors. It is anticipated that such an examination of appearance management behavior, sense of self-efficacy and self-esteem among female college students will serve as useful data for appearance-related industries by enabling them to properly under stand their clientele's psychological traits.

온라인게임을 개발하는 과정에서 게임을 검증하기 위한 베타 테스트는 반드시 필요한 과정이다. 베타테스트를 통해 예상치 못한 문제점을 발견하고 사용자들의 행태를 분석하여 단점을 보완한다. 베타테스트를 통해 많은 단점을 보완할 수 있지만 게임컨텐츠가 외부로 공개되며 시간과 비용이 많이 든다는 단점이 있다. 그러므로 본 연구에서는 베타테스트 기간과 비용을 줄이기 위한 방법으로 캐릭터간의 성장 밸런스와 캐릭터간의 전투에 대한 시뮬레이션 모델을 제안하였다. 그리고 이를 트라비아 온라인에 적용하여 개발 기간의 단축을 가져올 수 있었다.

Fretting, which is a special type of wear, is defined as small amplitude tangential oscillation along the contacting interface between two materials. In nuclear power plants, fretting wear caused by flow induced vibration (FIV) can make a serious problem in a U-tube bundle in steam generator. In this study, substructure method is developed and is verified the feasibility for the finite element model of fretting wear problems. This method is applied to the two-dimensional finite element analyses, which simulate the contact behavior of actual tube to support. For these examples, computing time can be reduced up to 1/5 in comparisons with conventional finite element analyses.

In this study, a stochastic finite element model is proposed with a view to consider the uncertainty of physical properties of discontinuous rock mass in the analysis of structural behavior on underground caverns. In so doing, the LHS(Latin Hypercube sampling) technique has been applied to make up weak points of the Crude Monte Carlo technique. Concerning the effect of discontinuities, a joint finite element model is used that is known to be superior in explaining faults, cleavage, things of that nature. To reflect the uncertainty of material properties, the variables such as the the elastic modulus, the poisson's ratio, the joint shear stiffness, and the joint normal stiffness have been used, all of which can be applicable through normal distribution, log-normal distribution, and rectangulary uniform distribution. The validity of the newly developed computer program has been confirmed in terms of verification examples. And, the applicability of the program has been tested in terms of the analysis of the circular cavern in discontinuous rock mass.

This study was undertaken to investigate the cutting behaviour of super duralumin (A2024-T3) with sintered carbide tool(P20). The cutting test was carried out under different conditions such as cutting speed, cutting depth and rake angle, etc. The specific cutting force Kc and Kt of vertical and radial forces decreases as cutting speed increases, especially the decrease rate of Kt becomes larger than of Kc as cutting speed increases. Kc and Kt in small cutting depth are much affected by work-hardening of surface layer. The chip width and shear angle become layer as cutting depth increases, especially chip width at feed of 0.1mm almost approaches cutting width. Relation between the friction coefficient of chip side and tool rake angle side can make the modelization studying the built-up edge size. The shear angle model equation of super duralumin generally agree with theory of Ernst-Merchant.

Since the government is fully aware of the specificity and importance of the healthcare field, it operates bureaucracy and affiliated organizations composed of many government ministries and experts and is also handling the related bureaus. However, recent incidents of humidifier disinfectant not only make these government activities unreliable but also cause disappointment to many people. Why did not the government take active measures to ensure product safety? But why was the Korea Centers for Disease Control and Prevention (KCDC) able to speed up the identification of the cause and the recovery of the product? The purpose of this study is to clarify the behavioral mechanisms of government intervention by comparing the behaviors of the Ministry of Trade, Industry and Energy and the KCDC. Then, we will discuss the desirable government structure.

In order to improve the accuracy and universality of the flow metric correlation analysis, this paper firstly analyzes the characteristics of Internet flow metrics as random variables, points out the disadvantages of Pearson Correlation Coefficient which is used to measure the correlation between two flow metrics by current researches. Then a method based on Symmetrical Uncertainty is proposed to measure the correlation between two flow metrics, and is extended to measure the correlation among multi-variables. Meanwhile, the simulation and polynomial fitting method are used to reveal the threshold value between different correlation degrees for SU method. The statistical analysis results on the common flow metrics using several traces show that Symmetrical Uncertainty can not only represent the correct aspects of Pearson Correlation Coefficient, but also make up for its shortcomings, thus achieve the purpose of measuring flow metric correlation quantitatively and accurately. On the other hand, reveal the actual relationship among fourteen common flow metrics.
