The purpose of this study is to investigate the properties of restaurant customer's choice and to present the desirable service of restaurants. The experimental data were collected from the questionnaire answered by 182 restaurant customers in Seoul. One-way ANOVA and $x^2$(Chi-square) verification analysis were performed with the SPSS WINDOW 10.0 program to investigate statistical significance of the data. As the results, it was revealed that the food factor was most important when the customers choose a restaurant. And then, the importance of the choice properties was in the following order, that is, the food factor, the hygiene and cleanness factor, the employee's service factor, the visiting convenience factor, the indoor mood factor, the menu factor, the amenity factor for children. In addition, it was confirmed that some choice properties of the customers are dependent on the general characteristics such as sex, age, occupation, income etc. Therefore, it is essential that restaurants should provide various services related with the choice properties by understanding the choice properties according to the customer's characteristics.

For the past several years, performance assessment has been widely used by mathematics teachers. The superiority of performance assessment items compare to multiple choice items has been discussed by many researchers, however these discussions tend to be lack of empirical data. Thus, this study aims to examine the effectiveness of tree response items in comparison with multiple choice items. Using the information function in Item Response Theory(IRT), item information of free response items and multiple choice items from the Third International Mathematics and Science Study-Repeat(TIMSS-R) were obtained and compared. Test informations of the whole mathematics area as well as each content area of mathematics were computed. On average, tree response items yielded more information than multiple choice items, especially in measurement and data interpretation. This study also revealed that free response items estimated students' mathematics ability more accurately than multiple choice items with smaller number of items.

The objective of this study is to investigate freight forwarders' airline choice behaviors in the Korean air cargo transportation market. This study identifies the major factors affecting airline choice and their relative importance by analyzing the data gathered by the survey from freight forwarders in Seoul. The questionnaire of the survey is composed of two parts; the first part is to identify the significant variables of airline choice and the second part is to gather the data about airline choice using stated preference techniques. The relative importance of major variables considered in forwarders' airline choice is estimated by the logit models calibrated with stated preference data. To strength the reliability of the analysis, this study segments the market by three routes; Seoul-Los Angeles, Seoul-Amsterdam and Seoul-Hongkong. The five major variables that are considered seriously in airline choice are reliability, space availability, frequency, cost and flight schedule. The utility trade-offs between variables are estimated by the ratio analysis of coefficients of logit model of each route, and the results of ratio analysis is interpreted as reflecting the reality of market conditions.

The sales volume of men's cosmetics has drastically increased in Korea. In recent years, men's needs for cosmetics have been diversified and the consumer demand for functional cosmetics has greatly risen. In particular, male consumers have become more interested in essence product that is a light and concentrated treatment to correct skin problems. This research analyzes consumer preferences for essence-for-men through the use of choice-based conjoint analysis. This approach is adopted since the task of respondents to choose the most preferred option from several alternatives closely mimics actual marketplace purchasing behavior by consumers. New technique for the construction of choice sets is suggested based on the balanced incomplete block design, to accommodate a larger number of product profiles. The proposed design for choice sets is balanced and provides a tool to filter the contradictory choices. Conjoint analyses are performed to assess the relative importance of attributes and identify the most preferred profile of essence-for-men with respect to attributes such as emphasized function, price, type of content, and design of container. Some differences are indicated in the analysis results between age brackets as well as between groups classified by the amount of fashion item expenditures.

The purpose of this study were the effects of principal related factors on the choice of the subject of environmental education in curriculum of middle and high school. We select 495 middle and high schools from 3 district of Chungbuk, Daejeon and Incheon. And, we send the questionnaires to the principals and withrowed answer questionnaire of 313(63.2%) from them. From the analysis of questionnaire, we obtained the reliability coefficient cronbach alpha value(0.8684). The results of this research as fallows : the principal factors that had chosen the subject of environmental education have significantly higher knowledge, recognition, attitude and practice than that not choiced on the subject of environmental education(p=0.000). The correlation between principal's attitude on the choice of the subject of environmental education and choice state of school was significantly higher than the other factors, and it's correlation coefficient was 0.328(p<0.01). Principal's attitude factor on the choice of the subject of environmental education have a great influence on his practice factor of them, and standard regression coefficient was 0.642(p<0.001). We found that principal's attitude factor on the choice of the subject of environmental education to have a great influence on the choice state of school in view of the results so far achieved.

A number of factors are thought to influence people's food choices, and there has recently been an increasing emphasis on understanding the consumer's motives behind choice of food types. For one thing, an individual's personal food-related tastes are thought to certainly influence personal food choice. This study aimed to discover the new motives for food, and what motives determine the food choice of foreigners living in Korea. Subjects (N=210) completed a Food Choice Questionnaire (65 questions) measuring specific motives and sociodemographic conditions (9 questions). Factor analysis and ANOVA were used to ascertain the food choice motives. Fourteen factors emerged, which were labeled health, mood, convenience, sensory appeal, natural content, price, weight control, familarity, political value, ecological protection. and religion. We also found that motives for new food choices include national image and information, ethnic food, and sanitation. Items were analysed to determine differences according to nationality, religion, occupation, and length of residence in Korea. All subjects thought sanitation is the most important motive in choice of food, and health, natural content, and ethnic food were also important.

Category Fuz of fuzzy sets has a similar function to the topos Set. But Category Fuz forms a weak topos. We show that supports split weakly(SSW) and with some properties, implicity axiom of choice(IAC) holds in weak topos Fuz. So weak axiom of choice(WAC) holds in weak topos Fuz. Also we show that weak extensionality principle for arrow holds in weak topos Fuz.

This paper is to develop a conceptual framework regarding the choice among dispute-resolution mechanisms in channels of distribution. These mechanisms are characterized by the division of labor in resolving disputes. The choice of the mechanism depends on dispute environments. These environments concern culture and stratification. Six propositions are addressed with respect to how the environments affect the choice of the mechanism.
