The aims of this study were to examine the actual conditions surrounding the purchasing of online game items and Internet cyberspace items by adolescents the propensity of adolescents to consume these items, to determine the difference in the propensity for high and low consumption of these items among adolescents, and to investigate the characteristics of the adolescents who show a high propensity for the consumption of Internet items. The data for this study were collected from 483 adolescent consumers who were middle school and high school students in the city of Bucheon in Gyeonggi Province. The statistical methods used for the data analysis included frequency, percentage, standard deviation, t-test, and one-way ANOVA. The results of the present study can be summarized as follows. The majority(79.5%) of the students surveyed had had the experience of purchasing items. Most students(67.5%) had a rare frequency of buying ($1{\sim}2$ times in a period of 6 months or less). Nearly half (47.9%) of the students spent less than 1000 won per month on the item(s) purchased. Most of the students purchased items with their parents' permission, but 26.6% of the students bought the items without their parents' permission. Most of the characteristics of the items purchased, such as the major item purchased, payment method, amount purchased per month, average amount spent per buying experience, and whether or not they had their parents' permission differed according to gender, grade level, record, and monthly allowance. The level of propensity to consume the items was not high. The propensity of imitation consumption (1.96) was lower than that of impulsive consumption (2.38) and conspicuous consumption (2.45). Most of the buying characteristics, including the major item purchased, payment method, amount purchased per month, average amount spent per buying experience, parents' permission, grade level, and monthly allowance were different between the high and low propensity for consumption groups.

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.

This study aims to understand how consumers consume by presenting the concept of 'consumption style' and the meaning of consumption for modern consumers. As modern consumers cannot lead their daily lives without engaging in consumption, their daily lives are deeply related to consumption. However, we have not been largely interested in how we manage consumption. It is a fact that marketing-oriented studies are focused on consumers for the establishment of corporate activities and strategies until now. For the analysis of the research, SPSS for Windows and AMOS were used. In order to examine the general characteristics of the investigation object, the technical statistics of frequency, percentage, average and standard deviation were obtained. To develop the research item analysis, Cronbach's ${\alpha}$, exploratory factor analysis, confirmatory factor analysis and cluster analysis were conducted. Based on the meaning of consumption through the consideration of preceding studies, the consumption style was extracted with 4 economic, socio-cultural, psychological and ethical perspectives. Also, 4groups were classified according to the type of consumption style: professional consumers, practical consumers, indifferent consumers and emotional consumers.

This paper aims to identify the characteristics of the tenant farm's income compared with farm household consumption. Farm household surplus is a critical criteria for the reproduction of agriculture. The degree of self sufficiency of farm household consumption according to agricultural income was rapidly decreasing for the period of 1980's. Only 78.9 percents of farm household consumption was earned by agricultural income. Tenant farms were classified according to the following characteristics; self-supported, semi self-supported, leased, deleted, over-consumption. Self-supported tenants are one of the backbones of Korea's future agriculture, because they are able to meet their household needs by only their farm work without other income producing endeavors. The rent paid by those tenants surveyed was estimated at 26.2 percents of their farm household income. However, the national average for such rental payment is equivalent to 4.7 percents of farm household income. 63 percents of paddy rental fee was paid by inkind of rice and 80 percents of the upland rental fee was paid by cash. Self-supported farms as 20 percents of total surveyed should be the target of agricultural price policy and semi self-supported & over-consumption farms as 30 percents be that of rural development policy, and the other half be that of social welfare policy.

This study was conducted in order to measure changes in the dining out consumption behaviors of the elderly living in Korea. Data on 2,316 and 3,170 elderly aged over 50 years were extracted from the 2001 and 2011 KNHANES(Korea National Health and Nutrition Examination Surveys), respectively. The data were analyzed by gender, age, region area, marital status, educational level, household income, economic activity and subjective health status. Frequency of dining out was higher in males between 50~64 years of age, living in metropolitan area, well-educated, high-income, engaged in economic activity and healthy. As a result, these basic data can be used for analyzing the changes in dining out consumption behaviors by sociodemographic characteristics of people aged over 50 years and the elderly in Korea. In the results on the consumption rate of food service in the two groups, 'female' and '65~74 years old' showed the largest increases from 10 years, and thus should be the group that the food service industry focuses on to develop new marketing strategies suitable for the environment.
