There are some factors affecting the shorebirds in selecting a coastal inland roost site where they have to stay during the high tide when the entire intertidal zone is covered with water. We investigated eight species (Eastern Curlews Numenius madagascariensis, Green Shanks Tringa nebularia, Bar-tailed Godwits Limosa lapponica, Grey Plovers Pluvialis squatarola, Dunlins Calidris alpine, Whimbrels Numenius phaeopus, Eurasian Curlews Numenius arquata and Terek Sandpipers Xenus cinereus) to identify the spatial and temporal variability in coastal inland roost use in the area and the factors influencing the use. We considered the area and length of the standing water in the roost site, temperature, wind speed, the time of migration and the intensity of disturbance. As a result, number of individuals and type of species using the roost site varied across spatial and temporal scales. And the factors affecting the roost use was species-specific. The roost site of the study area was a closed shrimp farm however, it has been converted to a Salicornia herbacea, a salt marsh plant, farm recently. In a situation where coastal inland roost site is needed, we hereby describe a resolution for the juxtaposition of shorebirds and farming.

We used the visitation aspect of dabbling ducks(Anas spp.) to investigate the estuarine ecosystem of Nakdong River and to compare the data collected during two periods: trom May, 1989 to April 1993 and from May, 2002 to April 2006. Over for the 8 years of field surveys, 356,110 individuals from 11 species of dabbling ducks(Anas spp.) were observed in the Nakdong estuary. In the early 1990s, the average number of species gradually increased from October through November, whereas the highest numbers of species were recorded in October during the second survey period. The average number of individuals recorded during the second period was 2-3 times higher than that observed in the 1990s. Statistical analysis using a t-test indicated that the number of individuals showed significant difference at 5% level between November and February in both the early 1990s and the mid-2000s. During the winter, dabbling ducks select both estuarine wetlands as resting sites and rice paddy as feeding sites. More wintering migrants including ducks would visit to Nakdong river if we provide with enough rice paddy near the estuary. The farmland around Nakdong estuary is used by dabbling ducks as a habitat, we hope it must be conserved thoroughly. CRP(crop reserve program), implemented by the local government of Kangseo-gu, Busan City is effective in conserving rice paddy; therefore, the CRP program need to be continuously applied in the Nakdong river basin.

If we look at Korea's urbanization since 1960, only the urban communities like buildings have developed, yet the resting places for human itself have been ignored. Many people continuously felt alienated especially after the mechanization and started to demand for better living space. For that reason, it is essential for us to develop the resting places for human among the buildings in urban areas and these resting places could form the basis of new community. We have researched on street furniture and citizen's behavior pattern in resting places through references and internet surfing to propose a design concept for a new resting place and street furniture, Therefore, we would like to design a resting place in urban area considering human, community and environment. As a result, we have designed a resting place where citizens could interact with surrounding environment and let office workers enjoy the nature among the buildings in this resting place. People could always stop by and take some rose by enjoying the surrounding nature. The resting place consists of 5 zones- public square, environmental zone, communication zone, technology zone, and entertainment zone. Each zone has its own design motif to lead systematic street furniture and site planning. The resting place is formed in a specific region which is a prototype of a resting environment in urban areas in the future and it could be reassigned according to its regional condition.

피로(疲勞)의 사전적 의미는 과로로 인해 정신이나 몸이 지쳐 힘든 상태를 말한다. 과도한 업무나 스트레스, 수면부족, 지나친 음주 등으로 인해 신체 리듬이 깨지면 피곤함을 쉽게 느끼게 된다. 대부분 충분한 휴식을 취하면 피곤함이 덜어지는데 휴식을 취해도 1개월 이상 피로가 계속되면 지속성(prolonged)피로, 6개월 이상 지속되면 만성(chronic)피로를 분류된다.

This study was conducted to investigate the bat's characteristic of using a bridge as a roosting site during the daytime and nighttime. 81 bridges built in the water system of the southeastern area of Gyeongsangbuk-do were investigated from Jul. 2007 to Oct. 2008. The species which use a bridge as a roosting site were 6 species of Rhinolophus ferrumequinum, Pipistrellus abramus, Hypsugo alaschanicus, Myotis petax, Myotis ikonnikovi and Eptesicus serotinus. There were 7 types of bridges in which three of them had a girder. This kind of structural characteristics are used for a roosting site of bats. There were other factors as well influenced on the utilizing it such as forest, vehicle passing under the bridge, and cultivated land around a bridges.

This study covers museum rest areas among the methods that reduce museum fatigue. The subjects of the study were Seoul branch of the representative National Museum of Contemporary Art and National Museum of Korea. These museums were compared and analyzed with The National Art Center of Tokyo and Tokyo National Museum. The first research step was the analysis of museums' floor plan, and the second step was the tracing survey of visitors' movement. The result of this study was as follows. The National Art Center of Tokyo and Tokyo National Museum had the rest space within the visitors' route along with good viewing areas. National Museum of Korea had poor viewing area even though there was the rest space withing the visitors' route. Lastly, Seoul branch of National Museum of Contemporary Art had the rest space out of visitors' route along with poor viewing areas. This study is meaningful in that it provided guidelines for museum space plan with visitors' route considered, so that their museum fatigue can be relieved along with the guideline that can be applied to space elements of rest space.

The survey of birds in Nakdong River Basin was conducted from March in 2003 to February in 2004. This study shows that the population of birds was 94,481 individuals and 114 species. The bird recorded in Daemadeung (Ⅰ) was 21,781 individuals and 55 species. It is surrounded with silt to have a better condition for a habitat and the rest place than other areas in the Nakdong River Basin. In the traits of the groups, Grebes were well established in the lower estuary(Eulsook islet), Cormorants in the main stream of the Nakdong River and around West Nakdong River (F). Swans, Shelduck and Shorebirds were using silt in the lower estuary where the depth of water is shallow, dabbling ducks were also established in West Nakdong River (F) and Yummak (C), diving ducks in the upper Nosan Watergate in West Nakdong River (F). Besides, land birds was distributed in the Yummak (C), Eulsook islet (A) and West-Nakdong River (F). Because they are connected with the artifical forest in Eulsook Islet Garbage Field and Ⅱwoong islet, it is good for the land birds and the water birds to have a habitat in this kinds of vacant lot. The Nakdong River Basin is not only an important area as the habitat and rest place for ducks and geese but also one of the areas where we can not get out of the temptation to development. To preserve effectively the natural habitat from human s intervention, it needs to keep supervising in Daejeo Watergate (E) and the upper area Noksan watergate in West Nakdong River (F) and Yummak (C).

This study identified the types and features of forest leisure activities based on data from the Nationwide Survey on Forest Leisure Activities (N= 6,191). Further, the study analyzed the demographic impact factors of the categorized forest leisure activities according to four types of objectives reported by visitors: health promotion, education, relaxation, and leisure sports. The investigation revealed that people visit forests for relaxation regardless of the season; however, leisure-sports visitors engage in activities that occur in summer, are most expensive, and involve the shortest trip time. The study also found that age, gender, household incomes, and the presence of children were the most important factors influencing the selection of activities. Age was found the predominant consideration: the older the age was, the more likely people were to prefer the relaxation and health promotion type. Men were more likely to choose health promotion activities over relaxation and tended to prefer educational trips over relaxation when accompanied by children. Higher household incomes corresponded to an increased likelihood of visitor preferences for relaxation over education and for health promotion over relaxation. This study contributes to the extant literature by statistically determining the nationwide predominance of age as the principal factor driving visitor preferences for forest leisure activities. Future studies should establish policy directions for forest welfare from the perspective of users grouped into day visitors and overnight guests.
