The Oxygen consumption of hybrid striped bass (Morone chrysops ♀ M. saxatilis ♂) was measured in relation to water temperature, salinity and photoperiod changes. Fish (574.0101.3 g) was individually exercised in a chamber for 24 h at 2$0^{\circ}C$, 24$^{\circ}C$ and 28$^{\circ}C$ with two salinity conditions (0 and 33 psu). Stepwise, the increase of water temperature induced a strong increase of the oxygen consumption. Salinity and photoperiod had an influence on the oxygen consumption of hybrid striped bass, even though there was not a consistent tendency between those.

This paper aims at finding out the optimum operating condition to reduce fuel consumption for the training ship Pusan 402 with controllable pitch propeller. For this purpose, this paper examints the variation of ship speed and fuel consumption in accordance with the change of engine revolution and propeller pitch. The results obtained are as follows: 1. When engine revolution is constant, the ship speed sluggishly increases according to the increase of propeller pitch but fuel consumption extremely increases. The higher revolution the engine is, the more remarkable this tendency is. 2. As the engine revolution becomes lower, the fuel consumption per mile decreases. Howt.er = the fuel consumption under the same engine revolution differs according to the propeller pitch. 3. Specific fuel consumption is uniformed about 180g/ps.h at any case of load. 4. Among the various operating conditions which yield the same ship speed, fuel consumption lowers in the case of lower engine revolution and larger propeller pitch.

This study examined the conspicuous consumption and consumption tendencies of the adolescent consumer and also identified factors that influence the adolescent consumer's conspicuous consumption and consumption tendencies. The data were obtained from a questionnaire completed by high school students(N=679), and were analyzed by ANOVA, and multiple regression analyses. The findings of this study are as follows: First, both the consumption tendencies and the conspicuous consumption of adolescent consumers were above average. Second, the consumption tendencies of adolescent consumers were related to the allowances they received. In particular, the consumption tendencies of adolescent consumers who spent allowances of more than won 20,0000 were higher than those of the other groups. In addition, the propensity for conspicuous consumption was related to the education level of parents, the parents' income, and the amount of the adolescent's allowance. Conspicuous consumption was shown to be higher when the parent's had graduate or postgraduate school degrees than when the parents were high school graduates. Although higher income was related to the propensity for conspicuous consumption, adolescent consumers who spent won 10,0000-20,0000 were more likely to exhibit conspicuous consumption than those who spend over won 20,0000. Third, the variables that had the most influences on consumption tendencies were commercials watched and the adolescent's group of friends, while the most effective variables that had the most influence on conspicuous consumption were consumption tendencies and consumer education level.

The purpose of this study was to identify household’s level and standard of consumption and their related variables in order to derive some useful implications for developing sustainable lifestyle. Data were collected from 567 household wives living in Seoul and the five Metropolitan cities in Korea. The results showed that most households owned such goods as central heating system, shower and bath, refrigerator, microwave oven, vacuum cleaner, washer. TV video player, personal computer, mobile phone, and car. They thought that most of the goods were necessary for the desired level of living and has a strong aspiration to buy those goods. This implied a tendency of uniformity in need perceptions and consumption patterns among Korean households. However, level and standard of consumption measured in selected living area differed according to age. education family size, household income, occupation, and the size housing, which showed that different approach was needed for developing sustainable lifestyle according to these variables.

Central control air-conditioning systems are being replaced with individually controlled air-conditioning system in the university. The amount of growth of electricity consumption is due to the increasing demand of electric heat pump. In winter and summer, the energy consumption showed a tendency to increase. On the other hand, showed less energy in spring and autumn. Increase the amount of electricity than the degree of decline in gas consumption was higher. Can be considered as transitional phenomena. Because electric heat pump, gas driven heat pump and the absorption chiller-heater are used at the same time in some of the buildings.

This various factors that affect beef consumption behavior between different types of beef such as Hanwoo, Australian, American, and domestic Yukwoo. Previous studies usually used almost ideal demand system (AIDS) model to show the degree of substitution between meats especially domestic and foreign beef. This a real expenditure each individual and to explain what factors affect consumers especially focusing on various beef. Hence, previous studies used shares and prices as key variableshowever, this study use various socio-demographic variables, consumption tendency, satisfaction and importance for beef consumption, purchasing usage and part, etc. This study a seemingly unrelated regression (SUR) model to enhance efficiency of estimates because error terms of four beef consumption equations are correlated. For, an on-line survey was performed Aug. 5 - 14, and we obtained 979 effective samples. The results show that high income group (more than 700 mil. won per month) purchases more beef than other groups. The origin of orders is Hanwoo, Yukwoo, Australian beef, and American beef. A family who member purchases more Yukwoo than other groups. foreign affects beef consumption regardless of its origin. Individuals who think origin and taste prefer Hanwoo.

The purpose of this study is to provide basic information to improve understanding of contemporary kimchi culture in Korea. Many Koreans are now purchasing kimchi at markets, while the proportion of self-preparation is gradually decreasing. This commodification tendency of kimchi is considered to be associated with changes in consumer's behavior and attitude. In this study, a linear regression and a logistic regression model were used to identify relationships between kimchi consumption behavior and household characteristics. The results showed that the probability of kimjang activity was positively related with family size, possession of a kimchi refrigerator, self-preparation practice, and the intensity of sharing behavior. I also found that kimchi consumption volume per capita of 'purchasing' household was greater than that of 'self-preparing ' or 'sharing-dependent' households, and that the number of family members was inversely related with kimchi consumption volume per capita. The inverse relationship between family size and kimchi consumption volume per capita is considered to be contrary to the widespread thoughts in Korea, which have been developed while experiencing kimchi preparation and consumption in traditional extended families. I think that the relationship comes from differences in menu varieties, which appear to vary with family size. This issue will be investigated in subsequent studies.
