In September 2008, the Korean government has legally pronounced criteria to designate the Impact Fee Zone on the basis of the population increase rate. Taking the Dongtan Newtown in Hwasung City as the case, the study tries a grid analysis method to figure out the cells that exceed the legal population increase rate criteria. The study then performs scenario analyses that try to envelope the cells into spatially contiguous groups based on their degrees of stepwise adjacency either by the cell buffer or the cell distance standards. By overlapping the selected cell groups over the actual land-use map for the vicinity, it is found that the selected areas reasonably coincide with the blocks of the high population density in the Newtown.

This study is performed to examine the meal management attitudes of housewives who had elementary schoolchildren in the remote rural areas(RA: n = 318, $37.2{\pm}0.3$ years of age) in comparison to those in their vicinity urban area(UA: n = 349, $36.9{\pm}0.2$ years of age) in the Chungnam province in Korea. The subjects were asked to fill out the questionnaire on their attitudes of meal management for their families. The results obtained in this study were as followings: (1) Most husbands of the subjects had a farming job in the RA while they had salaried workers in the UA(p<0.001). Education levels of both subjects and their husbands were lower in the RA than in the UA. Nuclear families were dominated by both groups, however single parent-family and step parent-family were more prevalent in the RA than in the UA. (2) in terms of ways of getting foods such as grains, meats, eggs, vegetables and fruits, the RA housewives relied more often on self-production than did the UA housewives(p<0.001). (3) The frequency of purchasing unprocessed foods was lower in the RA than in the UA(p<0.001). The RA housewives purchased the convenient foods such as instant noodles(p<0.05), ready to eatsoups(p<0.001), retort pouch foods(p<0.05) and instant teas(p<0.05) more frequently than did the UA housewives, while tuna, canned in oil(p<0.01), milk and their products(p<0.001), soybean products(p<0.001) and snacks(p<0.01) were purchased less often by the RA housewives. (4) Family members except housewives engaged more often in meal preparation in the RA than did those in the UA(p<0.001), which was more strongly observed for dinner. The time spent in preparing the dinner was shorter in the RA than in the UA(p<0.001). (5) The degrees of endeavor to provide the subjects' offspring with balanced meal(p<0.001) and nutrition education(p<0.01) were lower in the RA than in the UA. The RA housewives had more difficulty for performing meal management because of 'over work-related fatigue', 'insufficient money to purchase foods' and 'far distance from grocery' than the UA housewives(p<0.001). The RA housewives had lower score on nutritional knowledge(p<0.001) and wanted more strongly nutritional knowledge to improve the quality of family's meal than did the UA housewives(p<0.01). Therefore, the RA housewives had various problems regarding meal management such as 'over work related to fatigue', 'food-purchasing inconvenience', 'low economic status of family' and 'lack of nutritional knowledge'. As a consequence the RA housewives relied on cheap convenient foods more often in order to prepare the meal easily than did the UA housewives. These findings emphasize the need in the RA for nutrition education for housewives and a range of nutrition policies that focus upon the social and economic determinants of food choice within families to improve the nutritional status of the RA residents.

The purpose of this study is to assume the particular area of hills where it is highly possible for historical site to be buried in the viewpoint of geomorphology and based on this to suggest excavation-recommended area. Namely, this writer is to understand the dwelling site type of ancient people who had resided there at that time for the object of 'Ohnju region urban development business site' (referred as investigation area hereinafter) and considering the characteristics of micro-landform of hills which are distributed in investigation area and is to recommend the area where it is highly possible for historical site to be buried. The result of analysis is like the following. (1) Dwelling site types of ancient people who might have resided in the whole area of investigation region are discovered to be largely 'low hills+wetland' of Type-I and 'alluvial fan(or river terrace+wetland' of Type-II. (2) In investigation area if the area which has high possibility of distribution of historical site namely, excavation-recommended area is looked as based on micro-landform unit of hills, they are Crest slope and Crest flat. Individual area ratios which Crest slope and Crest flat occupies in investigation area are 12.9% and 10.2% respectively and the rankings are 3 and 6 each. And excavation-recommended areas in valley plain(or bottomland) of investigation area are in the vicinity of 'distal end' or 'buried distal end'of small scale alluvial fan.

This study deals with red tide detection by using the remote sensing imagery from the Geostationary Ocean Color Imager (GOCI), the world's first geostationary orbit satellite, around the southern coast of Korea where the most severe red tide occurred recently. The red tide zone was determined by the available data selection from the GOCI imagery during the period of red tide occurrence and also the severe red tide zone was detected through the spatial analysis by temporal change out of the red tide zone. This study results showed that the coast in the vicinity of the Hansan and Yokji in Tongyeong-si was classified into the severe red tide zone, and that the red tide was likely to spread from the coast of Hansan and Yokji to the one of Sanyang-eub. In addition, the comparative analysis between the area of red tide occurrence, the prevention activities of Gyeongsangnam-do provincial government and the amount of the damage cost over time showed close correlation among them. It is still early to conclude that the study is showing the severe red tide zone and the spread path exactly due to various factors for red tide occurrence and activities. In order to improve the reliability of the results, the more data analysis is required.

The garden soils, main road dusts, residential road dusts, and playground soils/dusts of Seoul, Geumsan, Onsan, and Taebaek areas were analyzed in order to investigate the level of heavy metal pollution by urbanization and industrialization. The soil pH is in the range of 5.48~8.40 and was generally neutral. The color of soils and dusts is mainly Raw Umber to dark greyish Raw Umber. Some samples from Taebaek city, a coal mining area, showed a deep black color due to contamination by coal dusts. Major minerals of the dusts and soils are quartz, feldspars, and micas, reflecting the composition of the parent rocks. However, pyrite was found as a major mineral in the samples of industrial road dusts of Onsan, a smelting area, and resicential road dusts of Taebaek. Thus, the high level of heavy metals in mining and smelting areas can be explained with the sulfide minerals. The mode of occurences of heavy metals in Seoul, a comprehensive urbanized area, were related to the metallic pollutants and organic materials through observation by scanning eletron microscopy. In main road and residential road dusts of Onsan area, Cd, Zn, and Cu were extremely high. Some industrial road and residential road dusts of Seoul area showed high Cu, Zn, and Pb contents, wereas some garden soils and residential road dusts of Taebaek area were high in As content. In general, the heavy metal contents in dust samples were two to three times higher than those in soil samples. Main road dust samples were the most reflective from the discriminant analysis of multi-element data. Cadmium, Sb, and Se in Onsan area, As in Taebaek area, Pb and Te in Seoul area were most characteristic in discriminating the studied areas. Therefore, Cd in smelting areas, As in coal mining areas, and Pb in metropolitan areas can be suggested as the characteristic elements of each pollution pattern. The dispersion of heavy metal elements in urban areas tends to orignate in main roads and deposit in garden soils through the atmosphere and residential roads. The heavy metal contamination in Seoul is characteristic in areas with high population, factory, road, and traffic decsities. Heavy metal contents are high in the vicinity of smelters in Onsan area and are decayed to background levels from one kilometer away from the smelters.

This study aims to analyze cold air characteristics in the watershed areas and to suggest strategies for utilizing them in urban ventilation corridor plans. For this purpose, the Jungnangcheon watershed and Uijeongbu-si in the northern part of Gyeonggi province, and Anyangcheon watershed as well as Yangjaecheon Tancheon watershed and Gwacheon-si in the southern part were selected as study areas. We used KALM (Kaltluftabflussmodell), a cold air simulation model developed in Germany and identified both the cold air flow and the height of cold air layer generated during 6 hours at night. Uijeongbu City is located on the main stream of the Jungnangcheon watershed, and the local cold air from the southern outskirts is an important part of Uijeongbu-si's overall ventilation corridor planning. In addition, the cold air generated in the vicinity of Mt. Sapae flows into the central business district near the city hall and plays a major role in regulating the thermal environment of the city. But, the cold air flows in the eastern part of Uijeongbu-si was not smoothly. The cold air flow generated in the east of Gwanak Mountain and in the west of Cheonggye Mountain was the most active in the northern part of Gwacheon-si. This flow is also a major ventilation corridor in Anyangcheon watershed as well as Yangjaecheon Tancheon watershed. But, the southern part where the cold air flow is not smooth is planed to be developed as 'Gwacheon Knowledge Information Town Public Housing District', so rapid development is expected in the future. Hence, it is suggested that an additional ventilation corridor plan should be established based on the detailed local wind flow analysis.

The Dresden Elbe Valley of Germany was delisted from the World Heritage List after a long dispute amongst the city of Dresden, UNESCO and the World Heritage Committee upon a plan to build a four-lane bridge within the boundaries of the property. The plan was claimed to threaten the Outstanding Universal Value of the heritage embedded in the view of the river landscape. However looking back on the necessity of the bridge in order to maintain the city dynamics and the needs of the local population, it is possible to diagnose that plans for the bridge had a rather different nature from the usual urban 'development' plans appearing in the vicinity of other World Heritage properties. This article examines the process that led to the delisting of the Elbe Valley from the World Heritage List and assesses the problems arising between the entities which determine the value of the heritage and the entities that implement conservation measures. Recognizing the necessity of involving the local residents, this article stresses the importance of the role of communities in heritage conservation. It is also important to set up dependable directions for establishing conservation policies which takes into account the changing dynamics of the living environment, and sound methods for assessing the impact of future projects on the heritage.

Since 1950, the city of Yokohama has been demanding the return of US. military base sites in Yokohama. Yokohama has established a systematic utilization plan for these relocation sites. The Fukaya communication site is one of former US. military bases verified for return in 2004. The Fukaya communication site is distinctively circular in shape and is entirely national land. Yokohama took an idea competition to its citizens to create a new park at the relocation of the Fukaya communication site, involving lots of citizen opinion in its utilization goals. This study determined the process of the idea competition at the Fukaya communication site in encouraging civic participation and analyzing citizen demands for the utilization of the relocation site. Through the idea competition, Yokohama city was able to obtain several ideas on the new park from various angles such as the function and shape of the urban open spaces. Citizens showed great interest in creating a park as green infrastructure on the Fukaya communication site. In addition, beyond utilization as an urban open space, many ideas suggested new lifestyles for the region in connection with the natural environment in the vicinity. Yokohama city tried to share the process and results of the idea competition with as many citizens as it could through a variety of means such as Participation, Judging, Support, Observation and Understanding. The case study on the idea competition at the Fukaya communication site is a good example of community design practice in public projects, and is full of suggestions for military bases in Korea, which has just established the plan of utilizing relocation sites as parks. Based on this case study, it can be concluded that it is important to make a systemic form for utilization planning with a clear process, open information and partnership in a variety of participatory design processes in order to ensure maximum civic utilization of relocation sites.

Changgyeongwon emerged as pleasure grounds following the creation of a museum, zoo and botanical garden in Changgyeonggung Palace during the Japanese colonial period. Pleasure grounds offer space for entertainment and have maintained the image of a paradise apart from reality. This study examined the creation process of pleasure grounds within a royal palace and the following spatial changes. By analyzing the image of Changgyeongwon as an artificial paradise, this study explored its landscape and cultural aspects. Literature reviews on the intention and process showed that the Changgyeongwon pleasure grounds were created as a 'royal garden' for the amusement of Sunjong, as well as 'public pleasure grounds' in the process of colonization. It was one of the first public spaces open to everyone who could afford the entrance fee. The layout of Changgyeongwon was studied by a comparison and analyzation of modern plans and photographs. It was composed of the central museum zone, northern botanical garden zone, and southern zoological garden zone. A conservatory and greenhouse to exhibit and maintain tropical plants were intensively built in the botanical garden zone while an aviary was created on the zoo pond. In the vicinity of the aviary a vivarium was constructed. Museum exhibition facilities included a main building as well as existing buildings, and a western flower garden was created between the buildings. Space for children including a playground and horse-riding course were created in the 1930's. The paradisiacal image and pleasure grounds culture of Changgyeongwon were studied as follows. Firstly, it shows that Changgyeongwon's paradisiacal image where rare animals and exotic plants were open to the public was promoted by the zoo and botanical garden. This led to the creation of new popular leisure activities such as flower appreciation and animal watching. Secondly, Changgyeongwon offered an urban leisure space, symbolizing the 'non-urban nature within the city' where the urban residents could escape from the daily routine. Thirdly, Changgyeongwon was known for its 'fantastic night landscape' by its night opening during the cherry blossom season. This cherry blossom viewing at night sadly degenerated by various shows and drinking, and as a result, an image of a deviant paradise was given to Changgyeongwon. Changgyeongwon contributed to creating a new space with its diverse facilities, and the public embraced the urban culture through experiences of pleasure and entertainment.

To alleviate the urban heat island phenomenon, this study aims to quantitatively analyze the effects of neighborhood green spaces on the improvement of the thermal environment based on detailed scenarios of five types of green spaces, including parks, pocket parks, parking lot greening, roadside planting, and rooftop-wall greening. The ENVI-met 4.4.6v model, a microclimate simulation program, was used to analyze the effects of green spaces. As a result, it was found that the air temperature decreased as the planting density of the park increased, but the thermal comfort index PET, which is the degree of heat sensation felt by humans, was not directly proportional to temperature. The establishment of a pocket park reduced air temperature up to a radius of 56m, while the range of temperature reduction increased by about 12.5% when three additional pocket parks were established at 250m intervals. Unlike the air temperature, PET was only affected in the vicinity of the planted area, so there was no significant difference in the thermal comfort of the surrounding environment due to the construction of pocket parks. Changing the surface pavement from asphalt to lawn blocks and implementing rooftop or wall greening did not directly act as solar shading but positively affected air temperature reduction; PET showed no significant difference. Roadside planting showed a higher air temperature reduction effect as the planting interval was narrower, but PET was not directly proportional to tree density. In the case of shrub planting under trees, it did not significantly affect the air temperature reduction but positively affected the improvement of thermal comfort. This study can outline strategies for constructing neighborhood green spaces to solve the urban heat island phenomena and establish detailed strategies for efficient thermal environment improvements.
