This study investigated slow fashion consumers from a human desire viewpoint in order to examine the psychological aspects of slow fashion consumption. First, the concept of slow fashion was defined. Second, this study reviewed the concepts of desire found in Oriental philosophies and applied them to slow fashion consumption. This process identified the fundamental desire that motivates consumers of slow fashion. Lastly, the psychological aspects slow fashion consumers were examined through a comparison of fundamental desire and external reasons given by interviewees in regards to personal motivation to purchase slow fashion products. Data were collected through in-depth interviews with 10 unmarried women 25 to 37 years old with experience in buying slow fashion products. Exploratory data were classified into external reasons and fundamental reasons to derive the concept of slow fashion. First, slow fashion is defined as sustainable fashion that considers humans and nature. It also seeks to produce morally good products that transcend time and space. Second, we identified the following external reasons: social responsibility, pursuit of healthy products, and pursuit of beauty. Finally, we extracted four factors that reflected fundamental desire: Recognition Desire, Ostentation Desire, Sexual Appeal Desire, and Power Desire. Altruism was emphasized by respondents who expressed social responsibility among external reasons and the desire for recognition among fundamental reasons. However, this goodwill also originated from human desire due to the emotional healing they receive from helping others. Interviewees sought psychological benefits such as self-satisfaction and spiritual growth through slow fashion that implied an Association of slow fashion consumption with human desire. Slow fashion consumption was influenced by moral convictions as well as various desires; in addition, external reasons for slow fashion consumption could be explained by desire.

In this paper, we attempted to suggest a way to evaluate appropriateness and efficiency for the energy consumption structure. For this, based on Markowitz (1952)' mean-variance portfolio model, we constructed an optimal fossil fuel mix. In constructing the optimal mix, we first defined returns on fossil fuels (oil, coal and natural gas) as TOE (Ton of Oil Equivalent) per $1. Then, by using the dynamic latent common factor model, we decomposed the growth rates of the returns on each fossil fuel into two parts : the common part and the idiosyncratic part. Finally, based on the results from the dynamic latent common factor model, we constructed the optimal fossil fuel mix implied by the mean-variance portfolio model. Our results indicate that for the fossil fuel mix to be on the efficient frontier, it is crucial to reduce oil consumption as low as possible. Moreover, our results imply that it is more efficient to increase natural gas consumption rather than coal consumption in reducing oil consumption. These results are in line with the strategies for the future energy consumption structure pursued by Korea and indicate that reduction in oil use can improve overall efficiency in energy consumption.

The socio-cultural and economic activities of users in virtual worlds are increasing, and virtual consumption of purchasing virtual products is expanding. The future growth potential of this virtual consumption market is very high and has the potential to change the existing traditional consumption ecosystem. This study was interested in the phenomenon of virtual consumption in the most rapidly growing gaming virtual world, and based on the consumption values theory and the concept of self-improvement, major factors promoting virtual consumption in the gaming virtual world were derived. Then, the influence of factors on intention to continue virtual consumption was verified. In particular, this study compared and analyzed whether the influence of factors varies depending on demographic groups (age group and gender) and types of virtual products mainly consumed. This study collected data from users who actually experienced virtual consumption in the game virtual world and empirically analyzed the influence of factors promoting virtual consumption and differences by group. Accordingly, it provides implications for knowledge management in terms of establishing a service development strategy in response to the virtual consumption phenomenon in virtual worlds, which will expand further in the future, and revitalizing the convergence economic ecosystem between the virtual and reality economy.

This study was designed to find out passible correlations between the growth rate and daily food intakes of two hundreds E and Y kindergarden children in Seoul, Korea. The subjects adapted in this study were 5-year-old boys and girls and their physical growth index was calculated by means of body weight and height. Dietary survey was performed by recording all the foods taken at daily basis for six days. The results are summarized as follows: 1. Living circumstances of the subjects. a) In most cases, subjects had two to three brothers and sisters. b) About 39% of boys were brought up by cow's milk and 34%, by mined nourishment with mother's milk and cow's milk, while approximately 40% of the girls were brought up by mother's milk and 37%, by mixed one. Of the whole subjects, 70% were weaned at the age of $7{\sim}18$ months. c) Fruit juices were introduced to children at about 3 months old in 40% of the subjects. d) Approximately 60% of the children had their meals regularly and the rest of the subjects had irregularlity in their meal, mainly because of excess consumption of snacks. e) About $20{\sim}40%$ of total income of sampled families were spent for foods. f) The most favorate main dish was steamed rice, other favorate foods were beef and pickled cabages for boys, and ham and dried laver for girls. The least favorate foods for both sexes were oyster, shellfish and various vegetabes. Fruits, juice, milk, and ice cream are more popular snacks among children. 2. Nutrition survey a) Insufficient caloric intakes were shown in both sexes, comprising 90% of daily recommended dietary allowences for boys and only 75% for girls. Iron intake was strikengly low, reaching only 62% of R.D.A. for boys and 72% for girls. b) The total caloric intake was composed of CHO 62%, protein 18%, and fat 21% respectively. c) The consumption of animal protein comprises 55% of total protein intake. d) The cereal consumption was found to be the highest at the level of 43%. e) When the total caloric intake was divided into each meal and snack, snack took the highest part in any other meal. Each figure showed as follow; breakfast 21%, lunch 27%, supper 22% and Snack 30% for boys, and 23%, 22%, 25% and 30% for girls, respectively. 3. The result of statistical analysis. a) There was a significant relationship between the growth rate and the caloric intake of the subjects at the level of 0.050.01.

This study was to investigate the value changes in Korean women by analyzing the ads of womens magazines. The contents of ads were classified into two types of values: general and consumption values. The general values, composed of inner-directedness and outer-directrdness, might predict consumer behavior in general. The consumption values, utilitarians and hedonic, were expected to affect the consumer purchasing attitude to a specific product. Factors affecting the cultural values were per capita income and womens social status. Total 2969 illustrated ads with verbal theme from 32 Korean womens magazines were used. The content analysis, chi-square test, logistic regression were done for the analysis. The results showed that inner-directedness was dominant general value in Korean womens culture and increased over time. Younger consumers were more inner-directed than older ones were, and inner-directed values increased with income growth. For the consumption values, utilitarian values were higher than hedonic ones and went up over time. For the product types, utilitarian ads were frequent in cosmetics while hedonic ads were high for apparels. Those results implied that Korean womens culture became more inner-directed with increased income. Also consumption values were likely to differ between product groups. Per capita income was shown to increase inner-directedness while womens social status was to increase outer-directedness.

Building energy consumption in university which is made up of many different kinds factor was researched. Central control air-conditioning systems are being replaced with individually controlled air-conditioning system. The amount of growth of electricity consumption is due to the increasing demand of EHP. Conversely, the demand for absorption chiller-heater is shrinking. Winter and in summer a lot of electricity and gas usage. 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 EHP and the absorption chiller-heater are used at the same time in some of the buildings. To use energy efficiently is needed additional research about environmental impact, economic evaluation.
