In the 1930s, The Architectural Association of Joseon run the ‘Architectural Material Display’ on the 2nd floor of the Japan Life Insurance Building in Hwanggumjeong(currently Euljiro street). The purpose of this place was to introduce new architectural materials to builders. And they issued a 『建築資料型錄(Architectural Material Catalog)』and distributed it free of charge so that people in districts at long distances can make use of it. This catalog contains descriptions, photographs and drawings of various architectural materials that were common at the time, and the overseas branch address of the store is stated. The purpose of this research is to investigate the type and characteristics of architectural materials distributed in Northeast Asia around the 1930s, the region of sale, affiliated companies by closely analyzing the 『建築資料型錄』.

백두대간은 한반도의 다양한 생물 서식지이며 동물의 이동통로로 새로운 서식지로의 이주와 재서식을 하는데 중요한 역할을 할 것으로 기대되고 있다. 본 연구는 2013-2014년에 4월부터 9월까지 백두대간 구룡령(명계리)과 고직령(서벽리)의 나비군집을 모니터링 하고, 두 지역의 나비를 과거기록과 비교하여 분포지의 변화가 있는지를 알아보았다. 그 결과 명계리 65종 1098개체, 서벽리 63종 1161개체가 조사되었다. 두 지역의 비교에서 명계리에서만 출현한 종은 15종, 서벽리에서만 출현한 종은 13종으로 나타났다. 종 순위별 개체수에서는 명계리는 큰줄흰나비 127 (11.6%), 줄흰나비 100 (9.1%), 산제비나비 90 (8.2%), 서벽리는 뿔나비 146 (12.6%), 줄흰나비 134 (11.5%), 네발나비 69 (5.9%)종으로 나타났다. 그리고 3개체 이하를 보인 종은 명계리 24종, 서벽리 23종으로 나타나 높은 비율을 차지하였다. 두 지역의 유사도는 비교적 높게 나타나고 있을 뿐만 아니라 한국적색목록의 나비가 다수 분포하고 있으며, 출현종을 과거 분포자료와 비교한 결과 뚜렷한 변화는 없었다. 이에 백두대간의 나비는 아직까지 잘 보전되고 있는 것으로 보여 거시적으로 백두대간의 서식지 경관이 연속성을 유지하도록 하는 것이 필요하다.

Genomic DNA samples isolated from four geographical freshwater crab (Eriocheir sinensis) populations collected in the inland of the Korean Peninsula (Gunsan, Paju, and Nampo) and a Chinese site, were used for PCR amplification. Seven decamer primers generated 19 specific loci (19/243 loci, 7.81%) in the Gunsan population, 32 (32/215 loci, 14.88%) in the Paju population, 19 (19/231 loci, 8.23%) in the Nampo population and 62 (62/340 loci, 18.24%) in a Chinese population. The average 8.9 specific loci exhibited inter-individual-specific characteristics, thus revealing DNA polymorphisms in the Chinese population. The number of unique shared loci to each population and number of shared loci by the four populations were generated by molecular analysis using seven primers in four populations. 35 unique shared loci to each population, with an average of 5.0 per primer, were observed in the Gunsan population, and 50 loci, with an average of 7.1 per primer, were observed in the Chinese population. The hierarchical dendrogram indicates three main branches: cluster 1 (GUNSAN 01GUNSAN 05, PAJU 06PAJU 10 and NAMPO 11NAMPO 15) and cluster 2 (CHINESE 16, 17, 18, 19 and 20). Conclusively individual no. 20 of the PAJU 10 freshwater crab was most distantly related to CHINESE no. 20 (genetic distance = 0.667). Taken together, these results demonstrate the potential of RAPD analysis to identify diagnostic markers for the identification of four freshwater crab populations.
