We installed mesocosms including zooplankton, fishs, artificial marshy land and aquatic macrophytes in Kyoungan stream to study the reduction effects of algae from Sep. 16 to Oct. 28, 2011. The control tendency of phytoplankton taxa was compared by analyzing community structure and dominant species in each mesocosm. Under the condition where Bluegill was absent, Daphnia similoides showed good effect of algal control since it has large food area and has high grazing pressure. Bluegill selectively preys upon large zooplankton, Daphnia similoides, as it also preys on small zooplanktons that flow in. In condition that Bluegill was absent, Daphnia similoides preyed selectively large phytoplankton (Cryptomonas ovata). Due to the shading of light, removal of nutrients and providing refuge for small zooplanktons, aquatic macrophytes and artificial marshy land showed high level of algal control. In corrals with aquatic macrophytes and artificial marshy land, the dominancy of genus Coelastrum and Pediastrum, which are difficult for small zooplanktons to feed on, relatively increased. In conclusion, under conditions of small number of predators such as Bluegill, Daphnia similoides is thought to be useful in algal bloom; however, when lots of predators are present, using small sized zooplanktons along with artificial marshy land and aquatic macrophytes is thought to be more useful than using large zooplanktons.

본 연구에서는 서울시 지하공간에서 화재발생시 재난관리 및 재난의료 개선방안을 지하상가를 중심으로 기술하였다. 먼저 지하공간에서의 법령 및 제도를 건축법관련, 안전관련, 소방관련, 피난관련으로 고찰해 보았다. 서울시 지하상가의 분류는 공간 및 형태적 유형에 따라 나눌 수 있으며, 유형별 형태에 따라 관리주체가 다르게 나타난다. 이러한 개별관리체계로 인하여 화재 및 재난발생 시 현장의 통합지휘체계와 현장 응급구조에 문제가 발생할 우려가 있어 향후 통합관리를 위한 대책 및 시설관리주체의 개선이 필요하다. 재해 발생 시 이송이 실제 현장에서 이루어지려면 의료진과 응급구조사가 존재하고, 현장지휘본부와의 협조가 원활해야 가능하기 때문에 평소에 재해정보와 응급의료정보가 실시간으로 파악되어야 한다. 따라서 수용의료기관 분포와 진료능력등을 고려하여 재해 발생 시 효율적인 대처방안 수립이 필요하다.

The objective of this study is to investigate the characteristics of the location and prospects of the bear shelves built by Asiatic black bears in the Jirisan National Park. Previous researchers have been analyzed bear shelves in terms of places for resting and eating, but we are going to analyze based on the prospect-and-refuge theory. Characteristics of the sites of bear shelves are measured through field survey and topographic analysis by using digital elevation model (DEM). The normalized difference vegetation index (NDVI) is used to evaluate the optimum location of bear shelves in terms of crown density. Man-made objects are identified by viewshed analysis based on geographical information system (GIS). Findings of this paper can be summarized as follows. First, most bear trees are located deep inside of the mountainous national park, slopes of 30~40 degrees, altitude of 400~1,200m, and relatively low vegetation density with NDVI value of 0.4~0.6 compared to the average NDVI of the park. Second, the average height of bear shelves is 12.44m, or 74% of the average height of bear trees. They are located at suitable places to observe nearby trails and other park facilities. Third, man-made objects within the 100m radius of bear trees include lodge, bear training center, beekeeping camp, and hiking trails. Thus we may temporarily conclude that one of the main criteria of the bear tree selection in the park has been to identify optimum places for the monitoring of human activities in their habitat.

본 연구는 가족실천을 하는 사회복지사들이 가지고 있는 가족담론의 내용과 의미를 파악하고자 하였다. 가족실천 과정에서 사회복지사들이 가지고 있는 가족담론의 내용과 특성을 파악함으로써 담론과 실천의 연관성을 시사받고자 하였다. 이를 위해 다양한 현장의 사회복지사 10명을 대상으로 심층인터뷰 하였다. 인터뷰 결과 가족실천을 하는 사회복지사들의 가족담론은 크게 4가지 주제로 나타났다. 첫째, 사회복지사들은 가족을 사적인 공간으로 이해하고 있었으며 그 공간은 안식처와 피난처로서의 의미를 가지고 있었다. 둘째, 사회복지사들의 성별분업 담론은 다소 의식과 실천상에 간극이 있었으나 전반적으로 성별분업에 공감하고 이를 실천에 적용하는 경향이었다. 셋째, 전형적 가족 이미지는 구조상의 전형성에 대해서는 어느 정도 융통성을 두고 있었으나 기능상의 전형성은 성별분업과 모성신화의 이미지에 기울어져 있어 절반의 전형성을 보여주었다. 넷째, 사회복지사들은 가족 유대의 질에 대해 자연적 제도이자 정서적 유대를 중요한 것으로 인식하고 있었다. 이러한 본 조사 결과는 사회복지사들이 가진 담론이 실천과정에 반영될 수 있는 여지를 보여준 것으로서 사회복지실천이 과학적 지식과 기술만을 적용한다는 이미지에서 담론적 혹은 해석적 실천일 수 있는 가능성을 시사해 주었다.

This papers is to find out the design theory of total healing environment through the studies on the mutually complementary roles of proxemics, which is the objective and numerical design indicator in the analysis of space and the spacial expression theory, which is the subjective and intuitive design indicator. 3 factors in the elements of total healing environment have the following relationship. And 8 behavioral affordance factors in the elements of spatial expression have the following mutual relationships; The physical factor of total healing environment has the relation with the work&study(+) and circulation(+), the psychological factor has the relationship with the rest(-),visual sequence(-),social exchange(+),refreshment(-) and meditation(-). In addition, the social factor of total healing environment has the relation with the circulation(+),social exchange(+) and community(+). And the work&study(+) and rest(-) of the refuge have the relation with the intimate distance and personal distance, the circulation (+) and visual sequence (-) of the flow has the relationship with the social distance. In addition, the social exchange (+) and the refreshment (-) of the prospect have the relation with the near public distance and the community (+) and meditation (-) of the void have the relation with the far public distance. According to the analysis, the cases in 5 children hospital were studied and the characteristics of total healing environment was evaluated for the spatial proxemics.

Philosophers Of aeBthetics have tended to limit their Suhject to include only objects Of art. In contrast to art objects, landscapes include elements of both art and nature, and the aesthetic experiences of landscape are ordinarty ones. Thus, the theoretical alternatives, that cannot be like the traditional aesthetic dogma of art, must be explored. Jay Appleton's theory is the firsts attempt to develop a comprehensive theory of landscape aesthetics. He concentrates on the question 'what do we like about landscape and why do we like it ' He takes the assumption that the aesthetic experience of landscape is pleasurable or satisfying, and suggests the biologically oriented theory, called 'prospect-refuge theory.'Although his theory is stimulating and highly speculative, it depends on the 'aesthetic attitude' theory of Kantian thought. His theory can be criticized for its biologically deterministic nature and its reductionism To respond to Appleton's shortcomings, that is, to resolve the conflict between biological and cultural explanations of aesthetic experience of landscape, Steven Bourassa tries to combine biological, cultural, and personal modes in a comprehensive paradigm for research in landscape aesthetics. This tripartite paradigm seems to promise to be meaningful if helping to pose important questions as well as in. avoiding conceptual errors about aesthetic domain of landscape. However, Bourassa's theory fails to integrate such three separate kinds of moder In the final analysis both Appleton and Bourassa present same succeases in expanding the scope of aesthetics to embrace landscape. Most important for a theory in landscape aesthetics must be its ability to enlarge our awareness of the aesthetic domain and its sound logic and evidence to criticize our problematic beliefs about he aesthetic idea of landscape.

The purpose of this study is to reveal the space composition of fireplace and common features of both Prairie and Usonian House found within Wingspread House. This house is the last and largest Prairie house and zoned house built in a Usonian period. However, this house is not an independent work, but rather Wright's evolutionary experiments of fireplace from his early works and his pursuit of Usonian ideal. This paper can be summarized as follows: 1) Living room has been transformed to allow spatial continuity towards exterior view and access and between neighboring rooms by removing doors and inglenook. At the Wingspread house Wright has introduced a freestanding fireplace in a living room with higher and prominent roof structure, therefore the space became a focal point as well as the central space of the entire house. 2) Wingspread and Coonley house have gallery space in common, but they have different settings in the living room composition. Also the living room and gallery space of Wingspread and Usonian houses have prospect and refuge principle by expansion and compression. 3) Wingspread house is a successful combination of Prairie and Usonian style to meet client's requirements in space composition and Wright's technology and economical experiments. This study is intended to reevaluate the significance of this house bridging his two great residential periods.

Adult mosquito surveillance was conducted from 2013 through 2014 at four cattle sheds, a wild bird refuge, and two residential areas located in Gyeongnam Province in the Republic of Korea. Adult mosquitoes were collected in black light traps from April 1, through November 30. Mosquito surveillance was conducted to figure out population densities of vector mosquitoes, possibly invaded mosquitoes and identify various virus infections at the selected sites. A total of 107,466 females comprising 14 species and 7 genera were collected from 2013 to 2014. The most common species collected were Culex tritaeniorhynchus Giles (63.8%), Anopheles sinensis s.l. (18.9%), Aedes vexans nipponii (Theobald) (7.7%), and Culex pipiens Coquillett (5.1%). Trap indices (TIs) varied widely for species over their range, due to geographical distribution and degree of association with rural and urban communities. The most collected An. sinensiss.l. and Cx. tritaeniorhynchus appeared at a cow shed in Hapcheon (TI 347.5) and a pigsty in Daejeo-1-dong, Busan (TI 1,040.8), respectively, due in part to their situation near breeding sites such as rice paddies. The bi-weekly population densities for mosquito species were variable for each of the years, apparently as a result of variable annual weather conditions. None of the mosquito species collected tested for the flavivirus including Japanese Encephalitis Virus, West Nile Virus, Dengue Virus, and Zika Virus infections by polymerase chain reaction (PCR) assay were positive.
