소환이식은 주환(主環)만 있는 둥근 고리형의 이식이다. 본고에서는 백제 분묘에서 출토된 소환이식을 대상으로 과학적 분석을 통해 역사적 요소와의 연관성을 알아보고자 하였다. 부여 합정리 유적에서 출토된 백제이식 6점의 조형적인 특징과 재료학적 특성을 현미경과 X선형광분석기를 이용하여 분석하였으며 분석결과를 토대로 이식의 성분조성비와 제작기법을 유추하였다. 분석결과 백제 웅진기에서 사비기에 이르는 시기에는 금과 은의 합금재료를 생산하는 기술, 가열 압접 기술, 아말감도금 기술 등 다양한 기술이 금공품에 널리 적용되고 있었다는 것을 확인할 수 있었다. 이러한 분석 연구는 차후 백제 이식의 시대별·지역별 상관관계를 알아보는데 비교자료로 활용될 수 있을 것으로 본다.

광주신창동 저습지유적에서 출토된 수침고목재 유물은 재질이 매우 취약하여, 공기 중에 노출되면 건조가 진행되어 곧바로 수축·변형이 일어나게 되므로 전시 및 보존을 위해서는 특별한 보존처리가 필요하다. 특히 칠기칼집과 같이 목재표면에 치밀하게 옻칠이 되어있어 칠기는 처리약제가 잘 침투되지 않고 처리 중 칠막이 부풀거나 탈락될 우려가 높아 보존처리가 매우 까다롭다. 칠기칼집은 낮은 농도의 PEG#4000 40% 수용액(水溶液)에 함침처리 후 동결건조하는 방법을 적용하여 보존처리 하였다.

약 1300 년 동안 봉안되어 통일신라의 정교한 금속 가공기술을 한 눈에 확인할 수 있었던 감은사지 동삼층석탑 사리함은 3층 탑신상부의 사리공에서 심한 손상을 입은 상태로 발견되었으나, 3년 8개월간의 과학적인 보존처리를 통해 거의 원형을 복원할 수 있었다. 수습과 보존처리 과정에서 발견한 사리함의 제작기술은 현대 금속공예 기술에서도 제작하기 어려운 우수한 기술 수준임을 알 수 있었다.

Recent conditions in North Sulawesi Province (NSP) have become favorable for the development of tourism. In this paper, we present the recent status of biodiversity and tourism in NSP as a basic consideration towards integrative biodiversity conservation strategy. Overall, biological accounts suggest that NSP is important for the world biodiversity conservation program. NSP's biodiversity makes the area a major nature-based tourism (ecotourism) site in the world. Development of diverse tourism programs in NSP has provided new opportunities for balancing development and conservation of regional ecosystems. However, the excessive tourism growth in some particular areas in NSP has been identified as the primary factor of environmental degradation. Nowadays, biodiversity of North Sulawesi regions are suffering from the number of tourist impacts and facilities. Based on those conditions, tourism planning and development in NSP is needed to formulate a proper strategy to protect the ecosystem and biodiversity from degradation and extinction. This will be a new challenge of sustainable island tourism development and biodiversity conservation in NSP.

The Choijin Lama Temple is a representative example of 19th- to 20th-century architecture. The temple has been damaged by various development pressures and the effect of a harsh continental climate. This study digitalized the entire temple site using three-dimensional scanning to establish the basic data of conservational management and monitoring for spatial changes. A terrestrial laser scanning model of the temple was completed, which showed low registering error vectors (3.73 mm average) and dense point distances. Unmanned aerial vehicle (UAV) photogrammetry was also applied to verify its applicability to the spatial and environmental monitoring of the temple. The results showed that the overall point density of the UAV photogrammetry model is similar within a 10 mm resolution. The relatively low RMSE of UAV photogrammetry from the ground to the uppermost roof indicates the high applicability of integrating it with the terrestrial laser scanning model. The digital documentation of the Choijin Lama Temple is expected to have a great ripple effect on the documentation, conservation, and utilization of Mongolian cultural heritage sites.

Many cities in Japan retain older city structures with buildings in traditional form and style. Visitors are fascinated by charms and tranquility of pre-modern life styles. Architectural features of olden days are well conserved or carefully restored on purpose. In the case of Kawagoe city near Tokyo, local residents are largely replete with visitors without being necessarily aware of slow commodification of historic spaces. Kawagoe is yet socio-culturally sustainable and financially fit. This paper intends to analyse conservation strategies, with focus on architectural heritage, taken for the historic city of Kawagoe. With the population of 300,000 in the suburb of Tokyo, it is one of the best known historic cities in Japan. Kawagoe grew as a merchant city since 1700s, and it once reached to a major port of silk trade en-route to Edo (Tokyo) from northen provinces. Tourism industry is discovered as a key element in the conservation strategies applied to revitalize historic city center, Ichibangai, an important cultural heritage site with special reference to kurazukuri. This paper argues that augmentation of conceptions in architectural heritage is not only advantageous for the conservation of historic urban environment but it also provides opportunities for sustainable urban renewal.

Designating conservation sites is needed for the preservation and management of tidal flats, and also objective criteria, by which preservation values of tidal flats can be evaluated, are required to designate conservation sites. A set of new evaluation criteria or tidal flats was suggested in this study. The criteria, based on six items including scarcity, diversity, naturalness, uniqueness, destruction possibility and preservation will, ave the advantages with which easy and economic assessments are possible by using basic data from the preceding studies. The evaluation results for the three different tidal lats (Muan, Jeungdo-1 and Jeungdo-2) in the southwestern coast of Korea reveal that all he tidal flats evaluated are classified into grade 2. The tidal flat which got the highest valuation score was Jeungdo-1 tidal flat (86.7), and the next was Muan (85.0) and Jeungdo-2 (82.5). The Jeungdo-2 tidal flat was superior in uniqueness and destruction possibility, and the Muan tidal flat was superior in diversity and naturalness.

This study suggested a vegetation restoration plan for a coastal area where the ecosystem conservation fund return project, targeting the whole area of Dalmaji-gil, located in Haeundae, Busan. After distinguishing if it would be a proper site for the operation of the ecosystem conservation fund return project by analyzing the ecological environment, human environment, and the current status of land owners, the target species for vegetation restoration was determined, and the facilities and programs were selected in accordance with the spatial division of the biosphere reserve. The basic direction is as follows. First, is the expansion of green space and the securement of life habitats downtown. Second, is the conservation of core areas by separating the conserved area from the space for use. Third, is the establishment of ecological resting space and the reinforcement of an ecological educational programs. The significance of this study is to suggest a vegetation restoration plan of a coastal area, fully utilizing the existing vegetation of the subject area, by suggesting the land use and flow planning, environmental improvement (vegetation restoration) plan, life habitats establishment plan, planting plan, and hydrologic plan, facilities, maintenance, and monitoring plan based on the basic direction. This study would provide useful basic data for ecosystem conservation and restoration in the Korean Peninsula, surrounded by the ocean on three sides.

The development of sex-specific genetic assays in a species provides both a method for identifying the system of sex determination and a valuable tool to address questions of conservation and management importance. In this study, we focused on the identification of single nucleotide polymorphisms (SNPs) that differentiate genetic sex in burbot Lota lota. Burbot are the only true freshwater representative of the cod family and a species of conservation and management importance throughout Eurasia and North America. To identify sex-specific SNPs, we utilized restriction site-associated DNA sequencing (RADseq) to interrogate thousands of SNPs in burbot samples of known phenotypic sex. We discovered 170,569 biallelic SNPs, none of which fit the pattern expected under female heterogamety. However, we identified 22 SNPs that fit the pattern expected under male heterogamety (males heterozygous XY, females fixed XX) and, from these, developed two genetic assays that robustly (~ 97% genotyping success) and accurately (> 99% correct) sexed burbot samples. These sex-specific genetic assays will benefit growing conservation aquaculture programs for this species and allow future assessments of sex-specific migration, growth, and mortality.

유구 전사용으로 수입되어 사용되는 우레탄 수지 NS-10을 대체하기 위하여 1 차 유구 전사용과 토층 전사용 우레탄 수지를 합성하였다. 합성된 우레탄 수지는 NS-10과 비교하여 볼 때, 수분을 함유하는 토양에서 같은 침투력을 갖고 있으며, 유구 전사 시, 최종생성물인 에폭시 표면과 우레탄 pre-polymer 층의 박리에도 안정한 도막층을 형성하였다. 1 차 유구 전사용으로 사용될 우레탄은 NS-10과 같이 강한 인장 강도를 부여하고자 했으며, 토층 전사용 우레탄의 경우에는 역시 NS-10과 같은 인장 강도를 가지되 NS-10보다 경질성을 증가시켰다. 이 경질성의 증가로 인하여 토층 전사 후에도 토층 전사체 후면의 작업을 최소화할 수 있는 장점을 갖게 되었다. 최종적으로 합성된 우레탄 수지들을 실험실에서 제작한 압착 토양과 실제 유구와 유사한 토양에 직접 적용하여 본 결과, 기존에 사용하였던 NS-10과 비교하여 만족스런 침투력과 안정성을 가지고 있는 전사체를 형성함을 보여 작업자에게 편의성을 주는 우수한 전사용 수지였다.
