This study aims to draw out planning principles and structure of Iksan imperial capital city in late Baekje, especially in view of the relationship among imperial capital city planning area, skeletal axis and the location of royal castle. With site survey and analysis of historical records, old maps, topographical maps, archeological excavation data, land registration map of 1915, some significant inferences were drawn out. Firstly from the point of topological conditions, the contiguous line of a stratum from Mireuk mountain(彌勒山) to Wangkung-ri castle(王宮里遺蹟) and two waterways made a topological axis of Iksan Imperial capital city. Secondly district of Iksan imperial capital city can be deduced to the inner area north to Kummado soil wall(金馬都土城), south to the confluence of Iksan river(益山川) and Busang river(扶桑川), west to Okum mountain fortress(五金山城) and Galjeon river(葛田川), east to line near to eastern wall of Jesuksa temple(帝釋寺). Iksan ssang-reung(益山雙陵) was located outside western boundary line of capital city. Thirdly axis from Wangkung-ri castle to northern Kummado soil wall made a skeletal axis of city structure. It got through northern lowland along Buk river(北川) between Yonghwa(龍華山) and Mireuk mountain. Fourthly the location of royal palace can be deduced to the north part of the city around Kumma town area along the planning principle of northern royal palace.

서태평양에 위치한 해저산 해역($150.2^{\circ}E$, $20^{\circ}N$ 부근)에서 수층 환경의 동적 특성을 파악하고자 수괴 및 용존산소, 무기영양염(질소, 인), 엽록소-a 등과 같은 수층 환경 인자의 거동을 살펴보았다. 2014년 10월에 해저산(OSM14-2)을 중심으로 동-서 및 남-북 방향으로 총 9개의 정점에서 CTD system을 이용하여 물리 화학적 자료를 획득하였다. 수온-염분 도표로부터 연구 해역에서 파악된 수괴는 표층에서 북태평양 열대수와 수온약층수, 중층에서 북태평양 중층수 그리고 저층에서 북태평양 심층수로 구분되었다. 용존산소 농도가 낮은 최소층(평균 $73.26{\mu}M$)은 산소 결핍 환경(dysoxic<$90{\mu}M$)으로 연구 해역 전반에 걸쳐 수심 700~1,200 m 사이에 분포하였다. 아질산염+질산염과 인산염으로 대표되는 무기영양염은 표면혼합층 내에서 빈영양 환경을 보인 후 수심 증가에 따라 점차적으로 증가해 용존산소 최소층에서 최대 농도를 나타냈으며, N:P ratio(13.7) 결과로부터 연구 해역은 식물플랑크톤이 성장하기에 질소 성분이 제한된 환경으로 파악되었다. 해저산을 중심으로 동-서 및 남-북 정점 라인에서 환경 인자의 수직 분포는 서쪽과 남쪽 해역에서 저층수 유입에 의한 영향으로 수심 500 m 부근에서 그리고 수심 2,500 m 이하의 저층 내에서도 서쪽 해역과 남쪽 해역에서 반대 해역과 비교해 환경 인자의 농도가 다르게 분포하였다. Redfield ratio(N:P=16:1)을 이용하여 구해진 Excess N 값은 연구 해역 전반에 걸쳐 음의 값을 보여 질소 제거 기작이 우세한 환경임을 나타냈으며, 서쪽 해역과 남쪽 해역 저층에서 상대적으로 높은 값이 관측되었다. 이러한 결과들은 해저산의 지형적인 특성이 저층 해류 순환에 영향을 미치고 이는 수층 환경 인자들의 거동을 결정하는데 중요하게 작용함을 지시한다.

This proposed simulation-based design study is based on the design of residential high-rise buildings in South-Korea. the purpose of this study is to evaluate the amount of daylighting performance passing through building glazing according to sky conditions, orientation of windows and each space of Apartment buildings. The clear sky includes sunshine and is intense and brighter at the horizon than at the zenith, except in the area around the sun. Daylight received within a building is directly dependent upon the sun's position and the atmospheric conditions. Orientation of the building generally used to refer to solar orientation which is the siting of building with respect to solar access. Although any building will have different orientations for its different sides, the orientation can refer to a particular room, or to the most important facade of the building. north-facing windows receive twice the winter sun than east and west facing windows, allowing light and warmth into the home. They can be easily shaded from the high summer sun to help keep the house cool. Ideally, the glazing area should be between 10-25% of the floor area of the room. This paper was calculated by a Desktop Radiance program. The space dimensions were based on a unit module of real constructed apartment having divided into five sections such as living room, room1, room2, room3 and kitchen.

Geological and electrical resistivity surveys were carried out to investigate subsurface geology and geologic structure of the Bonghwajae area in the Okchon zone. Pseudosections of the apparent electrical resistivity distribution along the three survey lines were obtained by using dipole-dipole electrode array method, and models of subsurface geology and geologic structure by using two dimensional finite difference method. The Bonghwajae fault zone exists around Bonghwajae area in the north-south direction, and is a boundary between Okchon Group and Choson Supper Group. Metabasite and hornblende gabbro intruded along the Bonghwajae fault zone remaining two fracture zones with low resistivity value of 20 ohm-m and widths of about 100m and 70-300m. They strike nearly N-S and dip westward with a high angle of $60-70^{\circ}$. Sochangri fault with a width of about 160m exists between Jisogori and Bonghwajae, by which Bonghwajae fault zone is displaced about 1km in the east-west direction. Hornblende gabbro whose electrical resistivity value is in the range of 5000-8000 ohm-m intruded the metabasite of 2000-4500 ohm-m after the Sochangri fault had formed. Great Limestone Group is widely distributed in the east of Bonghwajae fault zone, and interbeds so called Yongam formation of graphitic black slate with an extremely low electrical resistivity value of 2 ohm-m.

Recently, researches that are using deep learning technology in various fields are being conducted. The fields include geographic map processing. In this paper, I propose a method to infer where the map area included in the image is. The proposed method generates and learns images including a map, detects map areas from input images, extracts character strings belonging to those map areas, and converts the extracted character strings into coordinates through geocoding to infer the coordinates of the input image. Faster R-CNN was used for learning and map detection. In the experiment, the difference between the center coordinate of the map on the test image and the center coordinate of the detected map is calculated. The median value of the results of the experiment is 0.00158 for longitude and 0.00090 for latitude. In terms of distance, the difference is 141m in the east-west direction and 100m in the north-south direction.

Daecheongdo and Socheongdo Islands are located in the West Sea of Korea, 210 km away from land, and are military border areas very close to North Korea, making them difficult to access. Although the ecosystem of the islands is relatively well preserved due to the lack of accessibility, research on fungi of the regions is insufficient. Therefore, we aimed to investigate indigenous fungi in these geographically and geopolitically constrained regions. A survey of the indigenous fungal diversity of the islands was conducted in 2018. All specimens were identified at the species level based on morphological and molecular analyses. Among them, six macrofungi-namely, Agaricus menieri, Crepidotus praecipuus, Dichomitus squalens, Hortiboletus amygdalinus, Melanoleuca friesii, and Trametes lactinea-were not previously reported in Korea. Considering that the proportion of unrecorded species is high in the survey area and period as well as the number of samples collected, similar research on adjacent islands may be necessary.

We examined the species composition and community structure of demersal fish in the middle and southern coastal waters of the East Sea of Korea by surveying a commercial Danish seine fishery from 2010 to 2013. We considered the waters north of $37^{\circ}N$ as middle and those south of $37^{\circ}N$ as southern waters. A total of 79 demersal fish species belonging to 18 families were collected. Of these, 59 species (77.6%) inhabited only the East Sea as opposed to the West and South Seas of Korea, and most were resident species. The species and biomass were similar between the two portions of the study area. The sandfish Arctoscopus japonicus (78.0%) and the blackfin flounder Glyptocephalus stelleri (65.1%) were the most common species and accounted for the most biomass in the middle and southern waters, respectively. Fish were most abundant at shallow depths (50-100 m) in the middle portion of the East Sea. Using a cluster analysis, we divided the species composition and community structure at the sampling stations into three groups: middle portion (group A), deep area of the southern portion (group B), and shallow areas of the southern portion (group C). A. japonicas and G. stelleri were dominant in groups A and B, while G. stelleri and Clupea pallasii were dominant in group C.
