Fairy Pittas use the forest around the valley and Gotjawal as breeding places. This survey was conducted to investigate the characteristic of earthworms, specifically its population density, body size around the breeding site in Gotjawal and the forest around the valley areas from the middle of July to the end of July 2013. A total of 405 individual earthworms were collected in the 100 small established quadrats, in which 315 were found in Gotjawal and 90 were found in the forest around the valley area. The density of earthworms in Gotjawal was significantly higher compared to that forest around the valley area. It was also observed that the body size of earthworms was significantly different between Gotjawal and the forest around the valley area. Proportion of number of individuals which are larger than 7cm in body size was 43%(n=135) in Gotjawal and 84%(n=76) in the forest around the valley area, respectively. Soil area was not important factor to the density of earthworms. We suggest that Gotjawal can be considered as a suitable breeding site for Fairy Pitta because of the richness of its primary food in this area.

The grid-based analysis is useful for conservation planning, species distribution study, education, and others'. On the west coast of Korea, it was high in species richness, rarity and endangered species richness. Our results also showed that coordinated species data can be applied to develop species distribution models due to the high correlation between total species richness and coordinated species 0richness. In hot spot analysis, high species richness areas are concentrated around the west coast, while species richness is relatively low in Gangwon and Gyeongnam. Endangered species and rarity were also concentrated on the west coast and islands. Through the complementary analysis, we selected areas which are efficient to protect species; protecting more species while minimizing the conservation effort. Our result demonstrated that simply protecting Baengyueong island, Gageo island and a part of Jeju island can conserve over 50% of bird species in South Korea. However, the validity of our analysis was limited by the absence of data from national parks, and Baekdudaegan protected areas as well as inconsistent capacity among field researchers.

북한의 함경북도 신포지구에 원자력발전소 설립에 따른 생태환경조사의 일환으로 조류상조사는 2003년 2월 27-3월 4일까지 4박 5일간 수행되었다. 동해안 지역의 대표적인 식생인 소나무림과 해안가의 곰솔이 우점하는 지역으로 조류상은 이 지역의 대표적인 식생은 소나무림이며 주로 15-50년생으로 나타났다. 해안가에는 곰솔이 우점하고 있으며, 주로 방풍림의 역할을 수행하고 있었다. 신포 및 주변지역에 서식하는 조류는 사업부지를 중심으로 반경 50km 내에 서식하는 조류를 대상으로 조사한 결과, 총 170여종(18목 40과)에 이르는 것으로 나타났다. 천연기념물은 황새(Cygonia boyciana)를 비롯한 모두 8종으로 나타났다. 이 지역은 산림의 황폐, 밀렵 등 서식환경의 악화에도 불구하고 조류상은 해안가, 산림, 농경지, 초지 등 다양한 서식환경이 조성된 관계로 비교적 풍부한 것으로 보인다. KEDO 사업의 중단에도 불구하고 공사가 다시 시작될 수도 있는 점을 감안하면 보전대책 및 지속적인 모니터링이 필요한 지역이다.

This study was carried out to design a bridge-type ecological corridor plan in a forested neighborhood park affected by road construction in Dongjak-gu, Seoul. In order to study the site conditions, we analyzed topography, ecosystem structure, and user behavior and trail use. Existing vegetation was classified into 12 types. Based on a vegetation analysis, the Populus albaglandulosa and Robinia pseudoacacia communities, where planted species are dominant, were distributed extensively in the southern forest area. Planted areas with a single-layer structure of Korean landscape woody plants and Robinia pseudoacacia communities with a single-layer structure were distributed extensively in the northern forest and water-supply area. Based on a study of 28 quadrats, the similarity index between the multi-layer plant communities distributed in the southern forest and the single-layer planted areas was low. Twenty-four species of wild birds(355 individuals) were found in the survey area, including nine interior species and three urban species. The study of user behavior and numbers showed most users were walkers and few users were observed in the southern forest while most users were observed in the northern forest and water supply area. We selected some wild birds as model species to represent migrating species believed to use this park as an ecological corridor during migration. We suggested the new park plan include the following: improvement of vegetation structure for wildbird migration and habitat, connection of park trails for users and presentation of a landscape linked to nature.

The present research aims to consider the real remains of 2 suits of Kasaya owned by the Hwaeom Temple(華嚴寺) based on research results about Kasaya in the meanwhile. The present research on 2 suits of remains which are Royal gifts given to monk soldiers in case of a national crisis of the Joseon Dynasty has a big meaning in examining characteristics of Kasaya and grasping characteristics and structure of the 17th century's Kasaya of the Joseon Dynasty through dense survey and analysis according to components. If examining characteristics of Kasaya, the Kasaya of the Great Monk Seo San(西山) is composed on the basis of an initial form of Sun and Moon Light Patch's generation and the Kasaya of the Great Monk Byeok Am(碧巖) has a form that is separately attached through production of embroidery patch as a process of being settled down. If examining what surrounds gold thread in the girth and expression of Sumeru and Chaeunmun(彩雲紋), the composition of a form similar to an insignia badge, so because this is a Royal gift, this can be estimated as being analyzed in a Buddhism aspect by devising a design from the insignia badge at the time, with a meaning like an official uniform given to a monk. Although the insignia badge is a square, it seems that the Sun and Moon Light Patch is made as a rectangular form corresponding to the structure of Kasaya. In addition, it is thought that what the Samjoko(三足烏) idea which is a symbol of the Sun based on Buddhism and Taoism is used together with Yijoko(二足烏) even in expression of the Sun and Moon Light Patch in the Joseon Dynasty which was a Confucian country has a relationship with what a bird was expressed in the insignia badge of winged animals.

In Korea, the construction company has provided houses through apartment sales system. Residents have obtained a variety of information about their future house by visiting a sample house called "the model house" before they purchase home. Advanced technology such as web-based VOD or Virtual Model in recent years has gradually replaced those built environment. In 2009, the Ministry of Land, Transport and Maritime Affairs announced the restraint to the construction of sample houses. Instead, they highly recommended a Virtual Model House as an alternative solution. This study aimed to propose how to design the user-oriented virtual model house through the experiment and survey research. The 3D virtual model house of 85m$^2$ apartment was built and presented by two types (Type A: Bird's Eye View, Type B: Walk through View) on the web page. The subjects evaluated presence, spatial perception and cognition, and usability of each type after exploring them. The results are as follows. (1) The subjects' evaluation of presence showed Type B has more negative effects than Type A such as feeling dizzy or tired even if their values were not so high. (2) The subjects perceived and cognized both types of virtual model house more realistic for the expression of volume of space, the size of opening, and the arrangement of furniture than that of wall finishes and materials. (3) The usability of Type A was significantly higher than that of Type B.

National parks and other protected areas often do not adequately protect national biodiversity because they were originally created for socio-economic and/or aesthetic values. The Korean government has committed to expanding the extent of protected areas to fulfill its commitments to the Aichi Biodiversity Convention. To do so, it is necessary to quantify the current levels of biodiversity representation within existing protected areas and to identify additional conservation needs for vulnerable species and ecological systems. In this study, we assess the proportion of species ranges found in South Korea's protected areas, for the species documented in the 3^rd National Ecosystem Survey. We modeled the range distribution of 3,645 species in the following taxonomic groups; plants (1,545 species), mammals (35), birds (132), herptiles (35), and insects (1,898) using the MaxEnt species distribution model and calculated how much of each species' range is within protected areas. On average, 17.4% of plant species' ranges are represented in protected areas, while for mammals and insects an average 12.0% is currently conserved. Conservation representation for herptiles averages 9.3%, while it is 8.6% for birds. Although large proportions of species that have restricted distributions should be represented in protected areas, 17 plant species, two insects (Parnassius bremeri and Lasioglossum occidens), and one bird species (Phylloscopus inornatus) with ranges smaller than 1,000 ㎢ have less than 10% of their ranges within protected areas. Establishing specific conservation goals such as the protection of endangered species or vulnerable taxonomic groups will increase the efficiency of the biodiversity conservation strategies. In addition, lowland coastal areas are critical for biodiversity conservation because the protected areas in South Korea are mainly composed of high mountainous areas.

The purpose of this study was to analyze the brand preference, the clothing pursuit benefits, and the purchasing behavior of Chinese women. A survey questionnaire was distributed to Chinese women in their 20s and 30s. The surveys period was from 9th January 9th to $21^{st}$ February 2016. The respondents were 343 Chinese women living in Henan. The collected data was analyzed by frequency analysis, factor analysis, t-test, one-way analysis of variance, and Duncan's multiple range of verification. The key results of this study are herein summarized. The brands examined, listed in order of preference, are Ochirly, Only, Zara, Uniqlo, La Chapelle, H&M, Peace bird, Vero Moda, JNBY, and The Basic House. The five most preferred brands were then selected and further analyzed. For purchasing, the design and price were considered to be important, while for product evaluation, importance was given to the style, price, quality, and color. Factors important in the clothing pursuit benefits were found to be price pursuit, trend pursuit, brand pursuit, individual pursuit, comfort pursuit, and quality pursuit. Also, clothing pursuit benefits depends on the average monthly income, monthly clothing purchasing cost, and the education level of the individual. Lastly, we observed that the sources and store selection made noticeable difference in clothing pursuit benefits.

The Wintering Waterbird Census of Korea was started in 1999 and monitors 200 major migratory sites in South Korea. Waterfowl counts have been undertaken for more than 20 years since; however, a limited number of studies have analyzed the temporal patterns of waterfowl population. In this study, we analyzed population size changes of wintering whooper swan (Cygnus cygnus) at 112 monitoring sites from 2001 to 2018. The average number of whooper swans was $4,296{\pm}42.66$ and there was a trend for an increase in population size across the survey period. We found that the population in the Nakdong River Estuary, one of the major wintering sites over 18 years (26.22% of the national population), had rapidly decreased (-0.77% per year). Conversely, the whooper swan population in the Junam Reservoir and Sihwa Lake increased (+1.64%, +0.54% per year, respectively). Estuaries showed the highest dominance of whooper swans among the five different habitat types, accounting for 32.13% of the population. Reservoir/lakes had 30.60% of the total population and reclaimed lakes(18.24%), river (13.11%), and coast (5.93%) followed. The annual distribution of the whooper swan population in South Korea has been affected by various habitat conditions resulting from human activities and urbanization. To better understand the complex factors that can cause rapid changes in wintering waterfowl populations, it is necessary to integrate the data from the bird census program with environmental conditions to conduct in-depth pattern analyses over longer time periods.
