Korean peninsula is known to be far from the plate boundary and not to generate large-scale earthquakes. However, earthquakes recently occurred in Gyeongju (2016/09/12, $M_L=5.8$) and Pohang (2017/11/15, $M_L=5.4$). The interest in earthquake engineering has increased, and various studies are actively underway by recently events. However, the seismic station network in Korea is less dense than that of the western U.S., resulting in the lack of data for detailed analyses of earthquakes. Therefore, KMA (Korea Meteorological Administration) set up temporary seismic stations and recorded ground motions from aftershocks. In this study, characteristics of Pohang seismic propagation and generation of bedrock motion are analyzed through the aftershock ground motion records at both permanent and temporary stations, as well as through the collected geological structure and site information. As a result, the response at Mangcheon-Li shows evidences of basin effects from both geology structures and measured aftershock motions.

가뭄은 강수 부족 및 온도 상승에 따른 물 수지의 불균형으로, 그 특성상 점진적이고 홍수에 비해 피해규모가 광범위 하여 효율적인 대처방안을 마련하기가 어려운 특성을 가지고 있다. 현재 국내의 경우 가뭄관리를 위해 비구조적 대책 방안인 가뭄지수를 활용하여 해당 지역의 부족한 용수의 정도를 시 공간적으로 측정하고 크기와 강도에 대한 정량적 또는 정성적인 평가를 수행하고 있다. 그러나 대부분 강수 및 기온자료를 토대로 한 평가가 주를 이루고 있으며, 그나마 제공되는 지수들의 경우 가뭄을 나타내는 기준이 상이하여 사용자에게 많은 혼란을 가중시키고 있는 실정이다. 따라서 효율적인 가뭄관리를 위해서는 장주기 기상정보를 토대로 국가 또는 권역별 가뭄감시가 이루어져야하며, 기상 분만 아니라 지표와의 물 수지 해석이 반영된 수문정보(유량, 토양수분 등) 기반의 가뭄 정보가 생산되어야 할 것이다. 본 연구에서는 전지구 수문해석이 가능한 지표수문해석모형을 활용하여 남한에 대한 수문성분 기반의 가뭄평가를 수행하고자 한다. 우선 남한 전역에 대한 기상 및 지형 정보를 구축하고 지표수문해석모형에 적용하여 격자별 수문성분을 생산하였다. 수문성분은 가뭄평가에 필요한 정보로 전환되어야 하며, 본 연구에서는 빈도해석기법을 적용하여 가뭄에 대한 발생 빈도 및 규모를 정량화 하였다. 즉, 모형에서 산정된 수문정보로 부터 빈도해석을 수행하여 적정 확률분포형을 결정한 후, 해당기간에 대한 확률값을 산정하여 과거 대비 가뭄에 대한 여부를 판단하였다. 산정된 지수에 대한 평가를 위해 국내 과거 가뭄기록사례를 조사 및 기존 가뭄지수인 SPI 및 PDSI를 활용하였다. 평가 방법은 시계열 및 지역별 분석과 유역별 물수지 분석으로 구분되며, 주로 가뭄기간동안의 가뭄심도와 가뭄 발생 및 해갈에 따른 재현여부를 평가하였다. 평가 결과 가뭄발생 및 해갈시기 그리고 피해지역에 대한 표현에 있어 기록된 사항을 적절히 반영하는 것으로 나타났으며, 기존 가뭄지수 보다 가뭄 재현에 있어 비교적 신뢰성이 높은 것으로 확인되었다. 따라서 지표수문해석모형 기반의 가뭄평가의 경우 적용성이 우수한 것으로 판단되며, 이상의 연구결과는 향후 국내 및 동아시아 가뭄감시 전망에 있어 기초자료로 활용될 것이다.

The Purpose of this study is to analyze an active discussion in North America about the issue of community archives governance which mainly focused on 'participatory archives' model and from it, draws implications for the present stage of domestic community archives development. Traditionally in the United States and Canada, local community archives have been built mostly by mainstream cultural institutions such as public archives, public libraries, museums, and historical societies as a part of comprehensive documentation of the society at large. At the same time, they have been processed and managed in accordance with the institution's collection development policy. As a result, most community archives in North America are characterized as top-down community archives model (in contrast with down-up model of 'independent' community archives as a part of grass roots movement in the UK). Recently, the community archives in North America with these characteristics try to overcome their limitations, which result in 'the others' of community archives, through governance, that is, community-institution partnership. Participatory archives model which assumes active community participation in all archives processes is being suggested by archival communities as the effective alternative of governance model of top-down community archives. This discussion of community archives governance suggests progressive direction for the present stage of domestic community archives, which has been built mostly by various mainstream cultural institutions and still has been stayed in 'about the community' stage. Particularly, community outreach strategies that participatory archives model concretely suggests are useful as a conceptual framework in building community archives based on community-institution partnership in reality.

Seoul's community beliefs originated from the ritual performed by the shrines affiliated to each government office in the Joseon Dynasty. Lower branches of government officials were assigned to perform these rituals. Generally, these shrines were called Bugundang(府君堂). Records show that Bugundang(府君堂) was generally one to three units and enshrined the portrait of Bugun(府君), the worshipped, inside. According to historical records, the worshipped were mostly General Choi Young(崔瑩將軍) or Madame Song(宋氏夫人). In fact, however, each Bugundang(府君堂) worshipped different persons. Some of the worshipped were historical characters from the Goryeo Dynasty or the founding period of Joseon Dynasty, Guan Yu(關羽) and Zhuge Liang(諸葛孔明) that became gods after the Japanese Invasion of 1952, Wanggun(王建), Dangun(檀君), General Nam Yi(南怡將軍), Kim Yoo Shin(金庾信), Lim Gyeong Up (林慶業), King Gongmin(恭愍王), King Taejo(Lee Sung Gye, 太祖 李成桂), Joban(趙?) who is one of the supporters of the foundation of Joseon Dynasty, Sir Hong(洪氏大監) and his women who appear in the legend of Nanhansanseong(南漢山城) area, and many other historical figures. It is difficult to compare the rituals of these shrines from community Gut(Shaman ritual) performances of Seoul. According to historical records, Gut and ceremony coexisted in rituals. As time passed, these rituals spread as the community Beliefs of commoners and have been transmitted in the context of Seoul's cultural change. This study examined the existence of affiliated shrines of local government offices in the Joseon Dynasty and discussed the cases of Jangchung-dong Gwanseong Shrine(將忠洞 關聖廟), Bangsan-dong Seongje Shrine(方山洞 聖帝廟), and Seobinggo Bugundang(西氷庫 府君堂) to trace the succession of rituals at these shrines as folk customs of commoners. Bangsan-dong Seongje Shrine(方山洞 聖帝廟) spread to the public as Gwanwoo(關羽), who was considered the god of soldiers, transformed into the god of merchants along with historical transition. It clearly shows the process as to how merchants from a certain region developed a community religion. Jangchung-dong Gwanseong Shrine(將忠洞 關聖廟) is Bugundang(府君堂) of the soldiers of Nampyoug(南營). As the ritual was succeeded by a ritual group called Yeoungsinsa(永信社), composed of nearby residents, it was naturally spread and succeeded by the residents in local community. Seobinggo Bugundang(西氷庫 府君堂) was related to the changes in the historical background of ice gathering in the late Joseon Dynasty.

우리나라의 하천 및 호소에 유입되는 오염물질 중 약 30% 이상이 농업(경종 축산)활동 등에 의한 비점오염원이며 특히, 축산비점오염원에 대한 관리는 관련 분야의 특징에 대한 정확한 이해를 바탕으로 국내 실정에 적합하고 현실적인 정책과 제도를 개발하여 적용하는 것이 필요하다. 실질적인 정책과 제도의 개선안 수립 적용을 위해서는 축산비점오염물질 배출에 대한 신뢰성 있는 정량화가 선행되어야 하나, 모니터링 자료가 충분하지 못하여 실측자료에 근거한 부하량 평가가 어렵고, 토지이용, 강우강도, 경사도 등에 따른 비점오염물질과 수계 유입되는 유달부하량 정량화에 대한 연구사례는 적은편이다. 따라서 국내 실정에 적합하고, 현실적으로 적용 가능한 정책 및 제도 개선안 마련을 위해서는 합리적인 오염 배출량 자료와 저감방법에 근거하여 현실적인 대안을 도출하는 연구가 필요하다. 또한 이러한 실정을 파악하기 위해서는 국내 축산 밀집지역을 대상으로 하여 강우시와 비강우시 오염물질들의 유출 특성 및 배출농도에 대한 기초자료가 필요하며 이를 토대로한 특성파악이 가장 우선시 되어야 할 것이다. 따라서 본 연구에서는 축산밀집지역인 정읍시 덕천면의 덕천천 유역일대를 대상으로 하여 강우시는 년 5회 비강우시는 년10회 모니터링을 통해 기초데이터를 구축하였으며 유역특성을 고려하여 총 8개 지점을 선정하여 조사하였다. 모니터링 결과 비강우시의 수질농도 평균값을 살펴보면, BOD, T-N, T-P 의 경우 모두 상류지점에서 하류로 가면서 점점 감소하는 경향을 보였다. 특히 축사 밀집지역인 상류지역서 가장 높은 농도를 나타냈다. 강우시의 경우 하류부분에서 가장 높은 값을 보였으며 가축자원화시설이 위치한 지점부터 높아진 후 하류로 갈수록 점점 농도가 증가된다. T-N의 경우 축사와 농경지가 밀집되어 있는 포함하는 지점에서 높은 값을 기록하였으며, 유량이 많아지는 하류지점에서 가장 낮은 값을 나타내었다. T-P의 경우도 BOD와 마찬가지로 하류지점에서 가장 높은 값을 나타냈다.

The purpose of this study was to analyze , which was made in the late Joseon Dynasty to specify the vegetation landscape of the Donhwamun Gate area in Changdeokgung Palace. The study results can be summarized as below. First, based on "Jieziyuan Huazhuan(芥子園畵傳)", the introductory book of tree expression delivered from China in the 17th century, allowed the classification criteria of the trees described in the picture to be established and helped identify their types. As a result of the classification, there were 10 species and 50 trees in the Donhwamun Gate area of . Second, it was possible to measure the real size of the trees described in the picture through the elevated drawing scale of . The height of the trees ranged from a minimum of 4.37 m to a maximum of 22.37 m. According to the measurement results, compared to the old trees currently living in Changdeokgung Palace, the trees described in the picture were found to be produced in almost actual size without exaggeration. Thus, the measured height of the trees turned out to be appropriate as baseline data for reproduction of the vegetation landscape. Third, through the Rubber Sheeting Transformation of , it was possible to make a ground plan for the planting of on the current digital topographic map. In particular, as the transformed area of was departmentalized and control points were added, the precision of transformation improved. It was possible to grasp the changed position of planting as well as the change in planting density through a ground plan of planting of . Lastly, it was possible to produce a three-dimensional vegetation landscape model by using the information of the shape of the trees and the ground plan for the planting of . Based on the three-dimensional model, it was easy to examine the characteristics of the three-dimensional view of the current vegetation via the view axis, skyline, and openness to and cover from the adjacent regions at the level of the eyes. This study is differentiated from others in that it verified the realism of and suggested the possibility of ascertaining the original form of the vegetation landscape described in the painting.
