A large quantity of purified water sludge is generated in modern cities around the world. Dewatering is essential to reduce the volumes transported off-site for disposal. Traditionally employed methods such as solar drying methods are time-consuming. There are urgent demands for developing alternatives to dewater the sludge in a less time-consuming manner. In this paper, siphon method is proposed to dewater the high-water-content sludge with plastic drainage plate installed horizontally. A group of comparative tests are conducted to preliminarily investigate the dewatering behavior of the purified water sludge with siphon and solar drying methods, respectively. On the basis of the test results, the availability and effectiveness of the new method is verified. It may provide an innovative solution to treat the purified water sludge more effectively.

This study attempted to develop the directions for developing customized health tourism programs of Gangwon province. The data was collected by telephone surveys for 500 citizens in a metropolitan and regional cities in Korea in 2009. In conclusion, the province has many advantages to develop health tourism industries because the image of Gangwon health tour was represented to be generally positive and more than 65% of respondents were interested in participating health tourism of the province. The respondents also considered that the purpose of the tour is for relaxation rather than medical treatments. However, it requires flexible seasonal employment, scientific investigations of the natural environmental treatments and connectionwithleisureactivities, also need to collaborated with health and hospital services.

This study examined the relationships among children's attachment to the mother, trait anger, anger expression style, and emotional-behavioral problems in children. The subjects were 384 5th and 6th graders at elementary schools in J and G cities of Jeonbuk-Do. The instruments were Revised Inventory of Parent and Peer Attachment (IPPA-R), Stat-Trait Anger Expression Inventory - Korean version (STAXI-K), and Strength and Difficulty Questionnaire (SDQ). The major results are as follows; The level of children's attachment to the mother was negatively related to anger and emotional-behavioral problems, and the level of trait anger was positively related to emotional-behavioral problems. Children who have high anger expression and anger suppression tended to show more externalized behavior problems. Finally, the regression analysis showed that children's attachment to the mother and anger are revealed as significant factors in emotional-behavioral problems.

Tracheophyta produced in this island consisted of 77 families, 180 genera, 214 species, 28 varieties and 1 forma, lauriligonosa of which comprised species and varieties. As in the case of neightboring Nowhado, Bogildo and Choungsando islands, this island was also a supply source of fuel woods consumed mainly in Mokpo and Wando cities during the period of Japanese rule and for about a decade after the liberation of Korea in 1945. Consequently it was once almost deforested, but its restorative proces has successfully taken place for about 25 years and now Pinus thunbergii is distributed dominantly all over the mountains and plains of the island. The forest of the Seonangdang (shrine of a tutelary diety) at Bijari and the windbreak forests at Minari, Maengseonri and Soan High School compound were formed with the old trees of laurilignosa, such as Machilus thunbergii, Machilus japonica, Castanopsis cuspidata and Camellia japonica. These shelter belts were relatively well preserved.

It is required to response to the demand for new space due to high density of population and buildings in urban area. In particular, in case of big cities such as Seoul where the lack of new construction site due to the depletion of available space, existing buildings must be demolished for new construction. Utilization of urban underground space can be an alternative to solve for urban space problems. There are applications of underpinning methods using micropiles for existing buildings. Sometimes, the difficulties come from the compact space available for new foundation underneath the existing ones. In this paper, a novel underpinning method is introduced which can solve the space restriction problems underneath existing columns.

The idea that city culture can be employed as a driver for urban development has become part of the new orthodoxy by which cities seek to enhance their competitive position. Such development reflect not only the rise to prominence of the cultural sphere in the city development, but also how the meaning of culture has been refined to include new uses in order to meet the main objectives of sustainable development. This study focuses on the procedure how the cultural infrastructure and historical context can be applied for urban regeneration strategy. Two successful cases (Bilbao, Spain and Yokohama, Japan) were selected for analysis of strategies as a whole, background, main characteristics of culture-led urban regeneration strategies and their effect for urban regeneration have been analyzed in detail. In conclusion, lessons for the future development were suggested in terms of resources, planning and linking strategies.

KEPRI, the research institute for KEPCO, has started developing a DAS using wireless communication networks since 1999. The wireless networks adopted Radio Link Protocol (RLP) of Personal Communication Service (PCS) as communication protocol. It is the first time that PCS is applied to data networks for DAS. The communication protocol, RLP, makes the DAS networks simple and economically affordable when they are installed at widely dispersed small cities. But, RLP has problem when it send unsolicited message. This paper describes the implementing method of a wireless network using RLP and TCP/IP Network to cope with unsolicited message problem.

The objective of this research is to analyze how main social relation network of middle-aged women such as family, friends and neighbors, etc affects the preference for silver town. For this objective, structured questionnaires were distributed to 309 middle-aged women at the age of 40-59 years old living in Seoul and new cities of metropolitan area. Statistics such as ANOVA, Pearson Coefficient and Multiple Regression were adopted for statistical analysis. The main result of this research is as follows: First, housewives showed higher preference for silver town than people involved in other occupations. Second, though the relation of friends and neighbors among the social relation network of middle-aged women affected the preference for silver town, that of family did not affect significantly. The result of this research suggests that it is necessary to adopt policy considering the relation of friends and neighbors among the social relation network of middle-aged women so as to activate silver town.

The purpose of this study was (1) to investigate the level of environmentally conscious consumer behavior and support on the environmental regulation, and (2) to identify the influencing variables and causal relationship. Data were collected from questionnares with 1050 male and female consumers who were in the age of 20∼49 and residents of 6 cities(Seoul, Pusan, Taegu, Kwangju, Taejoen, Inchon). The major findings were as follows: (1) The level of environmentally conscious behavior was relatively high and differed significantly according to sex, age, education and marital status. (2) The level of support on the environmental regulation measures, consumers' support on the company regulation measures was most strong. (4) Sex, age, marital status, environment awareness and environmentally conscious behavior had positive effects on consumers' support on the environmental regulation directly and indirectly.

This study was conducted to investigate the effects of wearing behavior of clothing and dietary behavior, and psychological characteristics on the obese children. For this purpose, the questionnaire method was used and the subjects were 1,501 elementary school children in the 4th to the 6th grade and their mothers (1,459), in Seoul, Busan, Daegu, Gwangju, and Andong cities. The children were divided into two groups, such as a normal weight group (NWG) and an obese group (OG). There were significant differences in adaptability to the cold and the heat, and in wearing behavior of clothing for body shape between NWG and OG. Scores for balanced dietary behavior was higher in OG than in NWG while dietary control perceived by their mothers was better in NWG than in OG. Stress was lower and self-esteem was higher in NWG than in OG. Experimental tests are needed to analyze the behavior of obese children on the basis of the obtained results of this study.
