After excavation work of relics, historical site which has historically meaningful, are preserved using the various methods. There are three method in the relocation methods that are original relocation method, the remaining structure-peel method, and soil peel method. The original relocation method is restored after relocating in historical site such as residential site, iron foundry site, kiln site, old mound. The remaining structure-peel method are restored only the feature of exposed remaining structure using polymeric resin, when it is difficult to relocate the entire remaining structure. And soil-peel method is exhibited after peeling in case when soil layers such as grave of old mound, foundation of building site, sedimentary deposit layer, shell heap, and etc. Soil-peel method becomes important historical data of changes according to environment at that time, that is, flooding by storm, traces of fire and living features of that time such as heaps of shells discarded after eating shellfish and living wastes. In particular, in case of soil layer for preparing foundation sites of building by compacting in turn soils with different components such as clay soil, rough sand soil and etc, it becomes important data which can judge foundation technology of that time. It can be said to be an important data preservation method for utilizing these historical data as historical data as well as for the purpose of education, exhibitions and public relations which can be shared not only by experts but also by general public. In this paper, we present the reliable definition of soil-peel method in various preservation methods and explain the using polymer in this method. So, we will come up with the accurate index about this method that is used the eminent analysis method for soil layer.

Some of ecological factors and the early life history of endangered freshwater fish, Pseusobagrus brevicorpus, were investigated to proliferate artificially and to restore the population by release seedlings. The density of population in restricted area by small scale dam was 1.25 ind. $m^{-2}$, and the low capacity for reproduction having 200$\sim$250 eggs ind$^{-1}$. were thought to be a reason of this endangered situation. From the result of induction of natural spawning in aquarium after hormone injection it was considered that the spawning substrate would be aquatic plants with slender branches. The hatching was observed after 50 hrs after fertilization and the larvae showed aggressive behavior. Yolk was almost absorbed 3 days after hatching, and the larvae shaped tad-pole grew up to fry after 30 days. We discussed on the strategies for conservation of this species according to those results from investigation on ecology and early life history.

Jukseoru as an official pavilion of the government, one of the eight sceneries in Gwndong Area, is located on the cliff over Osipcheon River. This paper interprets form and space of the pavilion with restored old life by analyzing pictures of official party in 18th century in Chosun Dynasty. Every part of the space is occupied by persons by the class and duty: the pricipal guest, nobles, subordinates, gisaengs, court musicians, and guards from the high to the low and from the inside to the outside. Applying the analysis to the Jukseoru pavilion, the noblest lord takes sit on the platform in front of folded screen at main bay under checked ceiling, enclosed by low timber beam. The next northern end bay is a place for subordinates' and servants' waiting for preparation for rice wine. Southern end entrance bay is not a result of later addition but deliberately and originally made for lower place outside the railing of wooden floor: for a waiting woman gisaeng, and subordinates. Outside under the eaves on the platform with bedrock, artificial stone and soil is a place for court musicians, subordinates, and guards. The yard in front of the building is a place for preparing meals by cookers. Every detailed ornamental form is different each other by the place for the occupied class. Existing theory tells that the building, 7 bays gable-and-hipped roof, is a result of structural extention of 2 bays at the 5 bays gabled-roof. However, through the interpretation of old pictures and application to the pavilion, the present Juseoru is not a result of later structural addition, but deliberately designed creation suited to life in hierarchical traditional society.

낙동강 하굿둑(이하 하굿둑)은 1987년 부산 사하구와 강서구 사이에 건설되어 하류 지역의 바닷물 유입을 막아 부산, 울산, 경남 등에 안정적으로 생활·농업·공업 등의 분야에 용수를 공급하는 역할을 해왔다. 현재, 하굿둑의 수문은 낙동강 상류로부터 하류로 흘러내려오는 민물(담수)을 방류하기 위해서만 하굿둑 수문을 개방하고 있다. 하구는 하천의 담수와 바다의 염수가 서로 만나는 구역으로 바닷물과 염수의 밀도차에 의한 혼합으로 자연상태의 하구에서는 담수와 염수가 섞이는 기수역이 형성되며, 이러한 특성으로 하구 인근의 지역에서는 일반적인 하천 및 해양, 연안과는 분명히 구별되는 생태계가 조성된다. 하굿둑 건설이후 바닷물(해수)과 민물(담수)이 만나는 낙동강 어귀에 기수생태계가 사라지면서 바닷물이 유입될 수 있도록 하여 생태계를 복원해야 한다는 필요성이 제기되어 왔으며, 하굿둑이 지역에 기여해온 사실은 분명하나 하굿둑으로 인해 생태계 단절이 발생하고 기수생태계가 파괴되었기 때문에 이를 해결하기 위해서는 하굿둑을 개방하여 과거 기수생태계를 복원해야 한다는 목소리가 높아지고 있다. 이에 따라 정부에서는 하굿둑의 기수생태계 복원을 위해서 관계기관 합동으로 의사결정을 하고 효율적인 개방 방안을 모색하는 실무협의회를 구성하여 운영 중이고, 실무협의회 논의를 통해 5개 주요 관계기관(환경부, 국토부, 해양수산부, 부산광역시, K-water) 공동으로 "낙동강하굿둑 운영개선 및 생태복원 방안 연구용역"을 추진 중이다. 2018년 1단계 용역이 완료되었으며, 2019년부터 2단계 연구용역을 추진 중이고 하굿둑 개방의 수준별로 각종 영향을 검토한 후 대책을 마련하여 기수생태계 복원 방안을 수립하는데 그 목적이 있다. 2단계 연구용역에서는 과학적이고 합리적인 기수생태계 복원방안 마련을 위해서 실제로 해수를 유입시키는 3차례의 실증실험 및 수리모형실험 등을 추진한다. 기존 연구들에서도 수문개방에 따른 해수유입 영향에 대해 모델링을 통해서 분석했지만 이는 검증이 이루어지지 않은 결과로 이번 용역에서는 실제 해수를 유입시키고 염분의 침투 및 각종 수생태 영향을 모니터링 한 후 그 결과를 반영하여 모델링을 고도화하고 있다. 최종적으로 고도화된 모델링 결과를 기반으로 기수생태계 조성 방안별로 염분, 수질, 수생태, 침퇴적 등 각종 분야에 대한 정확한 영향을 분석하고 이에 대한 대책을 포함하여 최종적으로 바람직한 기수생태계 복원 방안을 제시할 계획이다. 기수생태계 복원 방안이 계획에만 그치지 않고 실행으로 연결시키기 위해서 필요성에 대한 이해를 바탕으로 공감대를 형성해 나아가고 있으며 지역주민, 전문가, 관계기관 등 민(民)·관(官)·학(學) 다양한 의견을 수렴하여 하구지역내 수량-수질-수생태를 종합적으로 고려하여 복원 방안을 마련 후 사회적인 합의를 추진하여 확정할 예정이며, 하구의 안정적인 관리를 위해 AI 등 4차 산업혁명기술을 적극 적용하는 스마트한 하구물관리(Smart Estuary Watershed Management)"를 활용한 "하구통합물관리" (Estuary Integrated Watershed Management) 등 과학적인 관리를 추진할 계획이다.

This study examined the degree of life satisfaction and quality of life of elderly people living in abandoned mine regions as well as the life quality factors that affected their degree of life satisfaction. A structured survey was used to look at their degree of life satisfaction and quality of life. The subjects were 167 elderly people aged 60 or older residing in abandoned mine regions in Gangwon-do. Their quality of life and degree of life satisfaction was moderate and when they had worked for a mine for a long time, their current degree of life satisfaction was high. In addition, religion affected their degree of life satisfaction and the residential environment and pleasant environment were highly influential in their degree of life satisfaction. Therefore, to improve the degree of life satisfaction of elderly people living in abandoned mine regions, it is essential to recover their hollow areas and create a pleasant environment by organizing their residential areas and enhancing their environment.

The factors of local disappearance and a plan of restoration fer Parnassius bremeri from Okchon-gun, Chungchongbukdo, Korea, were investigated. The population of this butterfly from Okchon-gun was much more abundant than the other areas of Korea in the past. But only two adults were observed in 1997 at this site and no more observation was made in 1998. So we considered that Parnassius bremeri is disappeared from this area. To know the factors of local disappearance of this species, we analyzed data of the monitoring from seven localities of Okchon-gun from 1990 to 1998 and also checked 252 specimens from this area by several collections. As a result of it, the habitat changes by recent road constructions and the frequent collecting activity around this area are shown as the factors for the local disappearance of this species. We are intending to establish the programs for restoration of Parnassius bremeri in Okchon-gun. Firstly, the breeding plan of this species was designed by investigation on life cycle. Secondly, the environmental conditions among seven localities were compared and the suitable places of the restoration were selected. The most suitable localities for restoration by this study were of two localities, Dongrakjeong and Jangwahri, which are considerd as highly successful breeding places in the view of growth condition of host plant.

도시에서 하천의 모습은 시대와 함께 변화하여 왔다. 치수의 대상이 되어 제방이 높아 졌고 사람들의 생활에서 조금씩 떨어져 나왔다. 고 밀도화가 진행되는 도시지역에서 치수사업으로 하천정비를 하면서 하도의 직강화 및 콘크리트라이닝이 일반적이 되었고, 하천을 복개하여 주차장이나 도로로 이용하게 되어 도시 생태계를 단절하고 도시인들의 정서를 황폐하게 만들었다. 이에 본 연구는 부산의 23개의 복개하천 중 주요 복개하천 20개소를 선정하여 복개하천의 관리 실태조사 및 복원가능성을 평가하였다. 평가방법으로는 해당하천을 총괄지수, 제방지수, 생태지수, 하천지수로 나누어 평가함으로써 부산시내 하천평가 및 복원가능성을 제시하였다. 연구순서로는 부산시 하천을 크게 4개의 권역으로 나누고 각 하천에 대한 문헌조사, 현장조사 후 하천평가(도시하천의 하천평가기법 개발 및 적용, 2007 윤세의)를 실시하였다. 평가 결과 도시화가 많이 진행된 유역을 가진 하천 일수록 모든 지수들이 낮게 나와 하천총괄지수와 도시화의 진행정도는 밀접한 관계가 있음을 알 수 있었다. 본 연구는 도심복개하천의 기초자료로서의 활용, 복개하천의 이용실태를 파악하고 개선방안을 제시해 기초 자료로서의 활용에 목적이 있다.
