Despite the abundance of research on alcoholic-beverage consumption in the food and beverage marketing literature, research directly assessing and comparing consumers' psychological motives for drinking different types of alcoholic beverages is relatively limited. There is also a paucity of research comparing drink-type specific consumption motivations in an Asian market. Paying attention to some recent new changes in the alcoholic-beverages market of South Korea, this study investigated South Korean young adult female consumers' alcoholic-beverage type-specific drinking motives. A self-administered online survey of 340 young adult female drinkers about their alcohol-consumption patterns, alcoholic-drink preferences, involvement with alcohol, and four types of drinking motives (coping, social, conformity, and enhancement motives) revealed differences in: (1) the association between the consumer's alcohol involvement level, alcohol consumption frequency/amount, and preferences for alcoholic beverages across different types of alcoholic drinks; (2) the underlying psychological motives for drinking different types of alcoholic beverages; (3) the association between consumption contexts and alcoholic drink types; and (4) the consumption patterns and drinking motives across different consumer groups that are segmented in terms of their most preferred type of alcoholic beverages. These findings point to the importance of investigating drink-type-specific consumption motivations in alcoholic-beverage consumption research. Limitations and implications for future research are also discussed.

In this study, we examined relationship among social class, conspicious consumption, dimensions of clothing price, and clothing buying behavior. The data were obtained by 290 female college students using questionnaire. The questionnaire were consist of four parts, dimensions of clothing price, conspicious consumption, clothing buying behavior, demographic factors. And the data were analysed with frequency, $x^2$-test, factor analysis, cluster analysis, ANOVA and Duncan test. The results were as follows. First, there was significant differences in social class and their attitude on dimensions of clothing price. Upper class consumers evaluate clothing price as Quality and dignity, on the other hand, lower class consumers perceived it as tendency for discount. Second, clothing selective standards was founded significantly different in social class. Clothing symbolic factor was more important to the upper class then lower class. Third, upper class consumers had a tendency of purchasing more clothes than lower class, and spend more money on clothing. Fourth, there was significant differences in conspicious consumption group and their attitude on dimensions of clothing price. Fifth, when conspicious consumption tendency is higher, importance of clothing price is highly perceived by college student. Sixth, Amount of clothing purchase and clothing expenditure were significantly different in conspicious consumption group. Consumers tend to buy more clothes and spend more money on clothes when they had high tendency in conspicious consumption.

This study was attempted to investigate the changes of specific fuel consumption, compression pressure and power output, consequently to obtain basic data on farm kerosene engine. The samples which are used in this study are a 4 cycle water cooled korosene engine for the use of K6-CT83 power tiller and a 4 cycle air-cooled kerosene engine for the use of G5L-3A water pump. The Korean Industrial Standards (K.S)KS-B 6002 "Test code of small internal combustion engine" was referred in carrying out this study, and its results are as follows. 1. According to load increasing, the speific fuel consumption of the engines generally decreases, however, in case of 10% over-loading it increases. 2. As a result of full load consecutive operation, according to passing of operating time, the amount of wear generally increases, consequently the speific fuel consumption also increases, and inversly the compression pressure decreases. 3. The changes of specific fuel consumption and compression pressure were closely related with time of piston ring exchange, and periodically about 100 hours the engines show the increase of specific fuel consumption and the decrease of compression pressure. 4. After about 300 hours, although the engine had new piston rings, the specific fuel consumption increase, consequently the engine needs boring. In actual use, it is impossible to operate consecutively on full load, therefore the boring time of engine is expected to come later.

This study reviewed the consumption patterns of high-income households and analyzed the ratio of major 6 expenditure categories including food at home, food away from horne, education, clothing, entertainment, and housing expenditure to total expenditure. We employed data from two different years (1997 and 1998) so that we could investigate the influence of the economy depression on the patterns and items ratio of consumption, For this purpose, the Daewoo Panel data were used. Also, data analysis was done with descriptive statistics, t-test, and regression analysis. The regression analyses were used to investigate the determinants of the high-income households' consumption patterns. The results of this study showed that food away from home, among 6 consumption items, seemed to be significantly affected by the depression, but still high-income households seemed not to lessen education expense. We included independent variables such as age, income, job, gender, debts and the likes. It was found that the age of reference person affected the amount of expenses for food, clothing, and entertainment. Other independent variables influenced different consumption categories. The results of this study would be useful for marketing strategies of fashion industries.

This study was carried out to verify the accuracy of fitness tracking devices in monitoring heart rate and energy consumption and to contribute to the development of a forest exercise program that can recommend the intensity and amount of forest exercises based on personal health-related data and provide monitoring and feedback on forest exercises. Among several commercially available wearable devices, Fitbit was selected for the research, as it provides Open API and data collected by Fitbit can be utilized by third parties to develop programs. Fitbit provides users with various information collected during forest exercises including exercise time and distance, heart rate, energy consumption, as well as the altitude and slope of forests collected by GPS. However, in order to verify the usability of the heart rate and energy consumption data collected by Fitbit in forest, the accuracy of heart rate and energy consumption were verified by comparing the data collected by Fitbit and reference. In this study, 13 middle-aged women were participated, and it was found that the heart rate measured by Fitbit showed a very low error rate and high correlation with that measured by the reference. The energy consumption measured by Fitbit was not significantly different from that measured in the reference, but the error rate was slightly higher. However, there was high correlation between the results measured by Fibit and the reference, therefore, it can be concluded that Fitbit can be utilized in developing actual forest exercise programs.

The purpose of this study was to identify consumption behaviors among children and to examine the differences according to sociodemographic characteristics, factors related to allowance, and parents' consumer socialization function perceived by children. The data were collected from 291 elementary school students in Busan. The results of this study were as follows. First, regarding parents' consumer socialization function perceived by children, the level of child's participation and influence in consumption decision-making was the highest, whereas the level of parent-child communication about consumption was the lowest. Second, consumption behaviors among children were identified into 5 groups: impulsive consumption group, rational allowance management group, friend-dependent purchase group, planned purchase group, and effective goods management group. There were significant difference among them according to child's sex, allowance amount, allowance frequency, parents' guidance about allowance usage, parents' check after allowance usage, and 3 categories of parents' consumer socialization function perceived by children. These results imply that consumer education for parents should be developed and activated to improve consumer socialization function of parents.

The purpose of this study was to test whether moderate alcohol consumption has any positive effect on lowering blood pressure among Koreans. Study subjects were Korean adults 20 years or older (n=5,234) who participated in the 2001 Korean National Health and Nutrition Examination Survey (KNHANES). Analysis of variance and analysis of covariance were used to construct univariate and multivariate models relating alcohol consumption to blood pressure for the analysis. After adjustment for possible covariates, drinkers (regardless of drinking level) had significantly higher systolic and diastolic blood pressure, compared with never-drinker for male subjects. Diastolic and systolic blood pressures were also significantly elevated with the drinking frequency and amount of alcohol intake among male subjects. For the female subjects, only diastolic blood pressure was significantly associated with the alcohol consumption at multivariate model. however, low level alcohol consumption did not show any sign of lowing effects on blood pressure. The result implies that moderate alcohol consumption did not have any positive effect on lowering blood pressure among Koreans for either sex.
