A 4-week energy balance study was conducted to estimate the energy expenditure (EE) of 7 high school age men, 16 to 18 year of age, by measurement of energy intakes and changes in body energy (BE) content (intake/balance technique), keeping their normal living pattern and maintenance body weight. Gross energy intake (GE) and fecal energy (FE) loss was measured by bomb calorimetry, Urinary energy (UE) loss was calculated from nitrogen excreted. Fat mass (FM) was determined from body density estimated from skinfold thickness. 1) Mean constitutional ratio of carbohydrate, protein and Int for the total energy intake was $73.7{\pm}0.3%$, $13.5{\pm}0.3%$ and $12.9{\pm}0.5%$, respectively. 2) Fecal energy loss was 2.4% proportion of the gross energy intake. 3) Mean daily metabolizable energy estimated by subtract fecal and urinary energy loss was $2582{\pm}61\;kcal$. 4) Total body energy change estimated from body composition change over 28 days was decreased $4309{\pm}1837kcal$. 5) Mean daily energy expenditure was $2736{\pm}59kcal\;(46{\pm}1kcal/kg$ of body weight).

This study was intended to investigated the relationship between habitual physical activity, nutrients intakes and urinary riboflavin excretion of elderly women and to compare riboflavin biochemical status of urban elderly women with rural elderly women. While average daily riboflavin intake of elderly women subjects was below Recommended Dietary Allowances for Koreans, riboflavin biochemical status was adequate in terms of average urinary riboflavin excretion. Urinary riboflavin excretion did not show significant correlation with energy expenditure, physical activity level and riboflavin intake. Nutrients intakes of urban and rural elderly women were not significantly different. However, energy expenditure and physical activity level were significantly higher, urinary riboflavin excretion was significantly lower in rural than in urban elderly women. It is suggested that riboflavin biochemical status was influenced by physical activity.

The bearing wall apartments which occupy the majority of multi-residential apartment buildings built in Korea, are known for having limited architectural plan flexibility, posing challenges in terms of maintenance and remodeling. The economic losses and environmental issues resulting from the reconstruction of bearing wall apartments are now accumulating to the extent that they are becoming a national concern. Multi-residential apartment buildings, which are now the dominant form of residence in Korea, must accommodate diverse customer needs and changes in life style. A new concept of Rahmen structure with architectural flexibility is Green Frame. GF multi-residence housing is expected to reduce construction costs and shorten the construction schedule by overcoming the shortcomings of conventional bearing wall apartments. This goal is consistent with the national policies that target the reduction of resource and energy consumption. In addition, GF will be established as a core contributor to achieving a reduction in $CO_2$ emissions, which will enable the sustainable growth of domestic construction industry, and address the low-carbon green growth drive implemented by the government.

Chinese economic growth and Chinese adoption of foreign cultures have changed varied phenomena, consumption patterns and consumer life-styles, in particular. In order to understand behavior of Chinese consumers, it is critical to explore their lifestyles and its effects on their purchase behavior. For attaining this goal, our research classifies Chinese consumer lifestyles related to cosmetics, into four types: brand oriented, price sensitive, rational consumption, and impulse buying. The research further analyzes the effects of consumer lifestyles on perceived value, satisfaction, and purchase intention in each case of skin care cosmetics and make-up cosmetics. Significant difference are found in perceived value, satisfaction, and purchase intention of skin care cosmetics exists between brand-oriented type and rational consumption type. This is also the case between rational consumption type and impulse buying type. Purchase intention is only found to be different between rational consumption type and price sensitive type. In case of make-up cosmetics, significant differences in perceived value, satisfaction, and purchase intention in the pairs of brand-oriented type and rational consumption type, rational consumption type and impulse buying type, and rational consumption type and price sensitive type. This implies rational consumption type should be more appropriate target consumers in the Chinese cosmetics market.

Twitter has been continuously growing since October, 2006. Especially, not only the users and the number of messages have been increasing but also a new concept in social networking called 'micro blogging' has diffused. Within Korea, service such as 'me2day' has already been introduced and the improvement of internet accessibility within mobile devices is expected to expand the 'micro blogs'. In this point, this research is executed to study the new medium, 'micro blog'. To do so, we collected and analyzed Twitter logs of Korean users. Especially, we were curious about the extreme heavy users using Twitter, despite of the linguistic and cultural barrier of the foreign service. Who they are, why and how they use the 'micro blog'. First, we reviewed the general aspect of followers and messages by collecting a certain number of random samples. Using the Lorenz curve we found out that there was the imbalance within the users and based on this phenomenon we deducted an extreme heavy user group. In order to perform further analysis, log analysis was performed on the extreme heavy users. As the result, the users used multiple mobile and desktop 'Twitter' clients. The usage pattern was similar to that of internet usage time but was used during their "micro" time. The users using 'Twitter' not only to spread messages about important information, special events and emotions, but also as a habitual 'chatting tool' to express ordinary personal chats similar to SMS and IM services. In this research, it is proved that 68% of the total messages were ordinary personal chats. Also, with 24% of the total messages were retweets, we were able to find out that virtually connected 'people' and 'relationships' acted as the dominant trigger of their articulation.

The purpose of this study is to investigate the relationship between the residential satisfaction and the residential satisfaction in the residential environment. For this study, we analyzed the main factors of occupancy satisfaction by integrating previous studies on brand and housing and purchase intention, developing a research model based on the theoretical study on occupancy satisfaction, and establishing a research hypothesis. The results of this study are as follows: First, the relationship between first brand image and occupancy satisfaction is statistically significant. Second, the relationship between residential satisfaction and residential satisfaction is significant. In addition, the relationship with prices acting as parameters is analyzed to be somewhat significant. Therefore, this study is expected to provide not only useful information in the relationship between apartment supplier and consumer, but also provide basic information on similar research. Therefore, this study is expected to provide not only useful information in the relationship between apartment supplier and consumer, but also provide basic information on similar research. However, due to limitations such as selection of control variables and analytical errors, future research should be conducted through development of more comprehensive and valid indicators.

The purpose of this study is to investigate the wise use and the management of intertidal environment. For tills purpose, we selected the Kanghwa island mudflat which is one of the most important intertidal region in Korea peninsula. The main research method is surface sediment and several map analysis. The results are as follows. (1) The study area is worldwide coastal wetland in view of ecology and geomorphology. But most of the salt marsh has been reclaimed since Japanese colonial period, the study area is mainly composed of mudflat. (2) The mean tidal regime of study area is 7.3m. From this tidal regime, the study area is subdivided into four distinct areas: the high intertidal area the middle intertidal area the low intertidal area and the shallow sea area terrestrial area near mudflat. (3) The mean particle size of surface sediment is sand 41.5%, silt 47.3%, clay 11.2%. This particle size pattern indicates the ecological characteristics of surface sediment of the study area. The proportion of clay is increasing to the open sea. (5) The pursuit of the wise use and the management must be implemented by the consideration of not only ecologic and sedimentary characteristics but also of the eco-tour site plan. And the entire use and management subject is different in each area.

This paper is to conceptualize the urban social circulation of water from the social constructivism and political ecology, and to analyze the history of development of social circulation of water, that is, the modernization process of water in Daegu. The development of social circulation system of water in Daegu can be divided into 4 stages, that is, the beginning stage of modernization of water mainly during the period of Japanese colonization, the take-off stage from the 1960s to the mid-1980s, the stage of reflexive modernization from the late 1980s to the 1990s, and that of neoliberalization of water since the 2000s. It can be seen that the development of social circulation system of water in Daegu has contributed the increasing urban population and economic development, especially supporting the spatial expansion of the city and the way of modern way of urban life. But the social circulation system of water in Daegu seems to meet with a lot of problems such as relocation of the water intake station, over-equipment of filtration plants, distrust on tap water, inequality of water use, readjustment of water charge, liquid waste from industrial complexes within the urban area, creative destruction of waterfront environment, and privatization of water.
