The purpose of this study is to investigate the realities of the husband's violence, to develop a scale to identify women who are victims of wife abuse and to provide evidence of the scale's validity. The Instrument entitled the Wife Abuse Inventory (WAI) and conflict Tactics Scale(CTS), are administered to 511 women who lives in Taegu area. The main results are as follows; 1) The CTS analysis shows the 42.5% of the sampled house wives are suffered minor violence and 9/0% are suffered violence form husband. 2) The WAI is factor analyzed to examine factor components within the scale. An examination of the rotated solutions suggested that WAI is composed 10 factors. These factor is labeled men's conception of supremency and aggression propensity, communication, economic difficulties and frustration, social activities, jealousy, children rearing, intimacy, family relationships in laws , affection, difference of culture. 3) an analysis of variance show the group mean score of the violence group and the mean score of the non-violence group on the WAI to be significantly different(P<.001). A discriminant analysis produce a significant discriminant function (P<.001). Using WAI scores as the discriminating variable, 81,15% of the violence and non-violence subjects are classified into their appropriate groups. This finding indicates that the WAI is a reliable device for screening violence and nonviolence group.

With the emphasis on core competencies, the University of Seoul has exerted efforts to reflect the importance of core competencies in university curricula. The main assessment tool used in Korea is the Korea Collegiate Essential Skills Assessment (K-CESA), developed by the Korea Research Institute for Vocational Education and Training (KRIVET). This study examined whether core competencies measured using K-CESA are valid as a tool for assessing educational achievements among college students, and analyzed the correlation between K-CESA scores and course grades. The analysis was performed on approximately 204 engineering students at the University of Seoul. According to the correlation analysis between core competencies and courses, MSC courses were shown to be related to the resource and through information use competency and higher order thinking competency. Through the Analysis of Variance, students in the accreditation programs and students living in urban area showed higher competency scores. In the multiple regression, it was shown that Accreditation and MSC courses grades were the important variables to predict the competency of the students. Based on these findings, we confirmed that the K-CESA tool has a certain level of correlation with academic performance and that it functions as one of several ways to evaluate the program outcomes of engineering education accreditation.

The purposes of this study were to assess the nutrition service importance and performance level in views of industrial employees and to explore the ways to improve the nutrition service quality. A survey of industrial foodservice operations scatterly located in Korea was undertaken and detailed information was collected from each, including surveys of 1,002 industrial employees. Statistical data analysis was using SAS PC 6.04 for descriptive analysis, t-test, and analysis of variance. The whole industrial employees assessed the importance and performance of the dieticians' role on nutrition service as '4.03' and '3.32' out of 5 respectively, which suggests that the industrial nutrition service needs to be improved. The variables which received higher scores than the average mean were safe meal provision, sanitation management and equipment & facilities management, whereas the score of individual nutrition counselling was low compared to other variables of nutrition service. Dietician's performance level scored by industrial employees was statistically correlated with the effect of industrial foodservice(p<0.01). The groups who scored low performance were characterized by labor work, experience with less than 10 years, single, aged below 29 years old, and female.

Soy sauce, a basic ingredient in Asian cuisine, is made of fermented soybeans, salt, water, and barley or wheat flour. The sensory characteristics of soy sauce are not only determined through its main ingredients but also by various flavor compounds produced during the fermentation process. This study was conducted to identify the sensory attributes of five different commercial soy sauce samples that differ in Meju types (traditional Meju or modified Meju) and usage types. Thirty three sensory attributes, including appearance (1), odor (16), flavor (14), and mouthfeel (2) attributes, were generated and evaluated by eight trained panelists. The collected data were analyzed by analysis of variance and principal component analysis. There were significant differences in the intensities of all sensory attributes among the soy sauce samples. Soy sauce made with traditional Meju had high intensity of fermented fish, beany, musty odors and salt, Cheonggukjang, fermented fish flavors. Whereas two soy sauces made with modified Meju were strong in alcohol, sweet, Doenjang, roasted soybean flavors. Two soy sauces for soup made with modified Meju had medium levels of briny, sulfury, fermented odors and bitter, chemical flavors and biting mouthfeel characteristic.

Despite the growing online exposure of retailes, offline retail channels still outperform online channels in the total retail volume of some countries. There is much interest in the physical layout plans of retail stores to expand sales. Product placement that have a large impact on customer purchasing behavior at offline retailers influences customer movement and sales volume. But in many cases, each retailer relies on unsystematic and autonomous product placement. When multiple products are sold with one purchase, the customer's movement for shopping may be evaluated in terms of customer efficiency and additional impulse purchase. In this paper, the social network is applied to sales data of a retail store and the result is used for evaluation of product placement and customer path. The frequent sales product composition was identified using k-core from sales data in the form of shopping baskets. The location was checked for the identified compositions of products, the spatial variance was measured and the customer's path was identified. With these results, the store arrangement of products was evaluated with appropriate improvement directions. The analysis method of this paper can be an alternative analysis approach for better layout of retail stores.

The Hemi-sphere projection method produces an image that includes all surrounding visual landscape from a view point. This characteristic can solve the problem of perspective method that has only a limited view angle, and thus can be a potentially effective method for the analysis of visual landscape. This study tried to adopt the hemi-sphere projection method in the evaluation of streetscape, and examined its effectiveness and possibilities. Computer animations using the perspective method and the hemi-sphere method were produced for Bang-Hak Ro, Seoul, and the kames of the animations were reclassed to identify the visibility ratio of physical elements(buildings, sky and mountains). A preference questionnaire was given to 51 university students, and the relationships between the visibility ratio and visual preference were analyzed. The results showed that visual preference of streetscape can be explained by three factors: Openness, Uniformity, and Variousness, accounting for 63.2% of the total variance, and among which Openness showed the highest proportion at 32.1％. The visibility ratio calculated by the hemi-sphere method yielded strong correlation coefficients with Openness, and it was much higher than with the perspective method. The hemi-sphere method also produced significant correlation coefficients about Uniformity and Variousness, but the perspective method could not. The results demonstrated that the hemi-sphere method can provide more accurate observation of visual changes, and that it can be an effective method for the analysis of streetscape.

For major structural components periodic inspections and integrity assessments are needed for the safety. However, many flaws are undetectable because sampling inspection is carried out during in-service inspection. Probabilistic integrity assessment is applied to take into consideration of uncertainty and variance of input parameters arise due to material properties and undetectable cracks. This paper describes a Probabilistic Fracture Mechanics(PFM) analysis based on the Monte Carlo(MC) algorithms. Taking a number of sampling data of probabilistic variables such as fracture toughness value, crack depth and aspect ratio of an initial surface crack, a MC simulation of failure judgement of samples is performed. for the verification of this analysis, a comparison study of the PFM analysis using a commercial code, mathematical method is carried out and a good agreement was observed between those results.
