The purpose of this study is to assess the sanitation level and purchase behavior of fishery products, and to identify management conditions of bad smell from cooking fish at home as perceived by housewives in a metropolitan area. Frequency analysis, descriptive analysis, and cross-tabulation analysis were employed as statistical techniques for current study. Total 270 were collected from housewives. The statistical variables included the kinds of cooking oil and the age of housewives, the types of hoods for fish roasting, the types of covers for fish grills, the number of family, the ventilation methods, and the maintenance of kitchen utensils based on family incomes, and they showed statistically significant differences(p<.05). Furthermore, the housewives whose sanitary cognition level for fishery products was high, the housewives whose level of purchase attitude was relatively high, and the housewives who utilized specialized kitchen utensils demonstrated statistically significant differences(p<.05). It resulted from the assessment of such actual conditions as difference of culinary environment according to the sanitation level of fishery products, the level of purchase attitude, and whether the housewives utilized special kitchen utensils or not. The more efforts were proved from those who had the intentions for improvement of an amenable culinary environment at homes, according to the higher income obtainers, the smaller nuclear family, the younger generation, whether the housewives utilized special kitchen utensils or not, and those who had the higher sanitary cognition level of fishery products. The above results were derived from an individual lifestyle or a dietary lifestyle, but eventually this seems to be related with the propensity and values hierarchy of individuals.

The purpose of this study was to describe the levels of market goods substitution of housework and find out the determinants on it in the domain of food among married female home-based workers. The data were collected from 169 married female home-based workers in Pusan and Kyungnam province, by self-administered questionnaires. Frequencies, percentiles, Cronbach's alpha, Pearson's correlations, and multiple regression were used to analyze the data. In the convenience foods, frozen foods had the highest substitution level, whereas prepared stew had the lowest. The substitution level of Korean traditional storage foods was the middle. And in dining-out service, the substitution level was mostly high: the level of delivery service was higher than that of dining-out. Compared to the previous research, these results showed that market goods substitution tended to increase, and its level in the domain of food will promote continually over time. The variables affecting the substitution level of convenience food were the number of family members, occupation, the existence of elderly/disabled person in the family, sex-role attitude, and weekly hours at home-based work. The substitution level of Korean traditional storage foods was influenced by sex-role attitude, occupation, education, monthly household income, and the existence of elderly/disabled person in the family. The significant variables affecting the substitution level of dining-out service were weekly hours at home-based work, the number of family members, occupation, monthly household income, education, and sex-role attitude.

The purpose of this study was to investigate adolescents' body esteem and clothing behaviors according to the sociocultural attitude toward appearance. The subjects were 750 adolescents in Daejeon and Chungnam province. The research method was a survey methodology and the measuring instruments consisted of sociocultural attitude toward appearance, body esteem, clothing behaviors, and subjects' demographics attributions. The data were analyzed by Cronbach's ${\alpha}$, factor analysis, cluster analysis, t test, $x^2$ test, ANOVA and Duncan's multiple range test, using SPSS program. The results were as follows. First, 2 dimensions(internalization and awareness) were emerged on the sociocultural attitude toward appearance, and adolescents were divided into 4 groups (unreceptive group, awareness group, internalized group, and receptive group) by the sociocultural attitude toward appearance. Second, there are some differences in adolescents' body esteem according to the sociocultural attitude toward appearance. Receptive group had the lower level on body esteem than unreceptive group. Third, there are significant differences in adolescents' clothing behaviors according to the sociocultural attitude toward appearance. Receptive group had the highest psychological dependency of clothing, clothing interest, clothing individuality, and clothing conformity among 4 groups.

This study attempted to examine a theoretical framework which synthesizes risk attitude, type of investment management and investment behavior and to provide the specific investment strategy by analysing several variables which have effect upon the investment behavior. The results of this research were as follow : 1. Risk attitude had significant differences by the variabels such as age, sex, education, income and debt/asset ratio. Also the type of investment management was influenced significantly by the variables such as age, education, occupation, income, total asset, debt/asset ratio, achievement motivation and risk attitude. The ratio of risky asset holdings was affected by the variabels such as age, education, occupation, housing ownership, income, total asset, debt/asset ratio, achievement motivation, risk attitude and type of investment management. 2. Among several variables affecting the ratio of risky asset holding risk attitude, education, type of investment management, debt/asset ratio and achievement motivation had direct effect on it. Besides age had indirect effect through risk attitude and age, achievement motivation and risk attitude had indirect effect through the type of investment management. 3. The results of this study showed that causal relation between input, throughput and output can be applied to household's investment behavior and the concept of risk or risk attitude can be applied to other fields except household's investment. Also it could be attributed to provide the investment strategy for improving level of household's financial well-being.

This paper describes the design and realization of full attitude system based on MEMS IMU and GPS carrier phase. The work can be divided into two parts: First, initial heading is determined by using two GPS receivers. And this paper discusses the usage of space geometry conditions to reduce the range of ambiguity search. The method presented in this paper was tested on the static. On the static condition, an accuracy better than 0.06 degrees for heading for 3.48m long baseline has been achieved. Integration of GPS and low cost MEMS IMU are used to realize the real-time heading attitude system. Second, level attitude (pitch and roll) is determined using the method of frequency-velocity for the feedback control. At the same time, the method using the attitude based on MEMS IMU to help determination of the range of ambiguity search is proposed. The results done on the sea show that an alternative means to provide real-time, cost-effective, accurate and reliable attitude information for attitude surveys. Though motivated by a big ships application, the design can be applied to other vehicles.

Traditionally most of studies on voluntary turnover have focused on identifying the determinants of it under the implicit assumption that negative attitudue raises turnover rate and, in turn, it undermines organizational effectiveness. But, recently many scholars have argued that more focus be placed on the functionalty than the frequency of turnover. Based on the recent trend of voluntary turnover, this paper is to analyse the differences of the Intention to Leave(IL) level according to job characteristics(job variety, job importance, job autonomy, job identity, feedback)$\times$functionality(employee ability, attitude). Resulting from 2-way ANOVA, the Negative-attitude Group(NG) is found to expose significantly high IL level than the Affirmative-attitude Group(AG) in low job variety, low job autonomy, low job importance.
