This study conducted a survey with 300 male respondents in their 20s to 50s, in order to examine the influence of personal variables, identity of gender roles, self-esteem and social-cultural attitude towards appearance on metro-sexual consumption. The findings are as follows: First, the majority of respondents experienced metro-sexual consumption in passive ways, such as purchasing cosmetics or perfume. Second, self-esteem differed by classification of identity of gender roles and the self-esteem was the most highly rated in non-classified, followed by in femininity, masculinity and androgyny. On the other hand, the non-classified group appeared to have the most highly social and cultural attitude toward appearance. Lastly, when examining the effect of personal variables, identity of gender roles, self- esteem and social-cultural attitude toward appearance on metro-sexual consumption, the results showed that the younger respondents who spend the highest monthly expenses on appearance, belong to the androgynous group and have the social-cultural attitude, are more likely to have a greater tendency towards metro-sexual consumption.

This study categorized consumer groups by their life styles and examined the differences in preferences for and satisfaction with retailing stores. The results of this study are summarized as below: First, consumers' satisfaction level was most high in department stores, and discounting stores, internet shopping malls, and home shopping channels took the next in order. Traditional Korean stores, on the other hand, were the last. Overall, preference level was high in discounting stores, department stores, and internet shopping malls in order. Second, the singles and the elderly tended not to be interested in societal issues and concentrate on consumption only. Third, the more interested they get in consumption, the more consumers prefer department stores, and consumers who are neutral in societal issues and consumption were more likely to prefer traditional Korean stores. In addition, those who participate in societal issues and concentrate on consumption preferred discounting stores, convenient stores, and home shopping channels in order. On the other hand, consumers who are more interested in societal issues and less concentrate on consumption were less satisfied with discounting stores and department stores, but more satisfied with internet shopping malls. Consumers less participating in societal issues and concentrating on consumption were more likely to be satisfied with department stores, but less with traditional Korean stores.

Wireless capsule endoscopy (WCE) is considered as recent technology for the detection cancer cells in the human digestive system. WCE sends the captured information from inside the body to a sensor on the skin surface through a wireless medium. In WCE, the design of low-power consumption devices is a challenging topic. In the Shannon-Nyquist sampling theorem, the number of samples should be at least twice the highest transmission frequency to reconstruct precise signals. The number of samples is proportional to the power consumption in wireless communication. This paper proposes compressive sensing as a method to reduce power consumption in WCE, by means of a trade-off between samples and reconstruction accuracy. The proposed scheme is validated under channel constraints, expressed as the realistic human body path loss. The results show that the proposed scheme achieves a significant reduction in WCE power consumption and achieves a faster computation time with low signal error reconstruction.

The alkaline comet assay has been used with increasing popularity to investigate the level of DNA damage in biomonitoring studies within the last decade in Western countries. The purpose of this study was to evaluate the usefulness of the alkaline comet assay as a biomarker of oxidative DNA damage for monitoring in the Korean population, and also to evaluate the effect of nutritional status and lifestyle factors on H2O2 induced oxidative DNA damage measured by the alkaline comet assay in human lymphocytes. The study population consisted of 61 healthy Korean male volunteers, aged 20-28. Epidemiological background data including dietary habits, smoking habits and anthropometrical measurements were collected through personal interviews. After blood collection, the comet assay in peripheral lymphocytes and plasma lipids analysis was carried out and the results analyzed. Tail moment (TM) and tail length (TL) of the comet assay were use\ulcorner to measure DNA damage in the lymphocytes of the subjects. Statistically significant (p < 0.05) positive correlations were observed between DNA damage (TM or TL) and smoking habits expressed as cigarettes smoked per day and pack years (r = 0.311 and 0.382 for TM, r = 0.294 and 0.350 for TL, respectively). There were also significant positive correlations between DNA damage parameter and waist-hip ratio. Higher plasma triglyceride levels were associated with increased damage to DNA. There were no correlations between the consumption frequencies of vegetables and DNA damage to the subjects. However, consumption frequencies of fruit and fruit juice intake were inversely associated with the TM and TL. The results indicate that die comet assay is a simple, rapid and sensitive method for detecting lymphocyte DNA damage induced by cigarette smoking. Consumption of fruit or fruit juices could potentiall modify the damaged DNA in the human peripheral lymphocytes of young Korean men.

The objective of this research was to analyze nutritional status and food consumption of children participating in the Posyandu nutrition program. A total sample of 300 children under five years had been drawn. Sample was divided into two categories namely high participation and low participation in the Posyandu nutrition program. The sample was selected from two sub districts of Cianjur District, West Java. The districts were areas with a high proportion of poor people and many of them take the benefits of Posyandu nutrition program conducted by the government. The participation of children (under five years old) in visiting Posyandus was relatively good, namely, 92.4% (for the high participation group). However, for the low participation group, the number of participating children was relatively low (28.3%). The average consumption of energy for children under five years old was still below the recommended dietary allowance < 80% of RDA, whereas the protein consumption was already above the RDA. The prevalence of underweight, stunting, and wasting among children were respectively 30.0%, 43.7%, and 12.3%. The activities at Posyandus had a positive impact on the nutritional status of children under five years olds, measured in terms of weight for age (W/A) and weight for height (W/H). The more frequent the visit to Posyandus, the better the nutritional statuses would be.

This study analyzed the changes in household consumption expenditure of retired households using Korean panel data. We compared the pre and post retirement-consumption levels in different consumption categories using panel data. Paired t-test showed that changes in the consumption patterns before and after retirement were not significant except for the households in the third net worth quartile. Analyzing the effect of retirement on the level of household consumption expenditure, this study found that the effect of retirement was not significant in overall, although retirement had a negative effect on the level of consumption expenditure among households in the lowest net worth distribution. Understanding changes in consumption patterns of retiring households provides important information to design social security policies.

This study was conducted to investigate effects of self concept of children consumers on consumption propensity of online items according to gender by considering that self, which means a thought on ownself, is expressed as online items in cyber space. Totally, 760 copies of the questionnaire were distributed and 716 ones were finally used as data for analysis in this study. The data were analyzed by using SPSS 14.0 and factorial analysis, Cronbach' ${\alpha}$, t-test, cross tabulation analysis and multiple regression were conducted. The results of this study could be summarized as follows. First, the factorial analysis performed to examine types of self concept found four factorial structures - justness, social, academic and family self. In addition, the factorial analysis done to determine compositional factors of irrational consumption propensity of children consumers showed three factorial structures - impulse buying, conspicuous consumption and imitative consumption. When the effects of personal variables, item-transaction variables and self concept on irrational consumption propensity of children consumers were investigated according to gender, significant factors affecting consumption propensity of both of the males and females were a monthly pocket money, time using the Internet and major transaction items. In addition, parents' permission for purchasing items, justness self and family self were found to be variables affecting consumption propensity in the male children. On the contrary, self concept of female children did not affect irrational consumption propensity.

The objectives of this study are to examine the degree of propensity for symbolic consumption among adolescents and its factors, and to investigate the effects of demographic variables - sex, grade, father's education, mother's education, father's job, mother's job, monthly allowance, monthly household income - self-esteem, and socialization agents variables - parents, friends, mass media - on the propensity. In this study, the propensity for symbolic consumption is defined as the propensity to consume products through their affective, subjective, and symbolic value rather than through their practical and utility value. The data used in this study were collected from 509 adolescents who are in the 2nd grade of middle or high schools in Pusan. The research results can be summarized as follows: 1. The propensity for symbolic consumption were found to have significant differences according to sex, father's education, mother's education, mother's job, and monthly allowance. 2. It differs significantly according to adolescents' self-esteem. That is, the lower self-esteem adolescents have, the higher propensity for symbolic consumption they show. 3. It also differs significantly according to the degree of communication with parents, the degree of accepting friends' view, the degree of communication with friends, the degree of informative influence from friends, and the degree of taking in mass media.

The object of this study is the introduction and the application of Ecological Footprint(EF) for sustainability of regional people activities. It is a tool for the evaluation of specific projects through various lifestyles or consumption to area of broad policy and budgets. But in Korea there is no assessment for consumption level of human activities by EF. Therefore this study try to analyse ecologically productive land for human activities of Cheju-island in order to assess the sustainability in Cheju and compares with another industrized countries. We analyze the human activities level of Cheju-island then the EF is about 0.9(ha/cap). This value is not more than another countries like Canada and United States. EF assists in choosing technologies, policies and Life Cycle Assessment(LCA) which can perform a certain task with the smallest ecological footprint. It will help society to avoid collapse and move towards sustainability and ecological efficiency.
