Various social and environmental problems have recently emerged due to global climate change. In South Korea, coniferous forests in the highlands are decreasing due to climate change whereas the distribution of subtropical species is gradually increasing. This study aims to respond to changes in the distribution of forest species in South Korea due to climate change. This study predicts changes in future suitable areas for Pinus koraiensis, Cryptomeria japonica, and Chamaecyparis obtusa cultivated as timber species based on climate, topography, and environment. Appearance coordinates were collected only for natural forests in consideration of climate suitability in the National Forest Inventory. Future climate data used the SSP scenario by KMA. Species distribution models were ensembled to predict future suitable habitat areas for the base year (2000-2019), near future (2041-2060), and distant future (2081-2100). In the baseline period, the highly suitable habitat for Pinus koraiensis accounted for approximately 13.87% of the country. However, in the distant future (2081- 2100), it decreased to approximately 0.11% under SSP5-8.5. For Cryptomeria japonica, the habitat for the base year was approximately 7.08%. It increased to approximately 18.21% under SSP5-8.5 in the distant future. In the case of Chamaecyparis obtusa, the habitat for the base year was approximately 19.32%. It increased to approximately 90.93% under SSP5-8.5 in the distant future. Pinus koraiensis, which had been planted nationwide, gradually moved north due to climate change with suitable habitats in South Korea decreased significantly. After the near future, Pinus koraiensis was not suitable for the afforestation as timber species in South Korea. Chamaecyparis obtusa can be replaced in most areas. In the case of Cryptomeria japonica, it was assessed that it could replace part of the south and central region.

이 글은 이민윤리가 이민행정의 합리성 수준에 영향을 미치는 핵심 요 인들 가운데 하나라는 전제하에 ‘비정규 체류 이주민’에 대한 한국 정부 의 체류관리에 나타난 이민윤리 결핍을 문제시하고 개선 방향을 제언한 다. 먼저 이주민의 비정규 체류를 유발하는 복합 요인, 즉 ‘불법화’ 메커 니즘에 대한 정부 대응의 한계를 검토한다. 이어서 국가의 기본 책무들을 보다 균형 있게 추구하면서 ‘불법화’에 실효적으로 대응할 수 있는 ‘다부 처 협력’의 필요성과 정당성을 논증한 뒤, 추진 원칙으로 ‘공동의 차별화 된 책임(Common But Differentiated Responsibilities, CBDR)’을 적용 할 것을 제안한다. 글의 후반부에서는 CBDR에 기반한 다부처 협력의 필 요성이 높은 대표적인 정책으로 볼 수 있는, 비정규 체류 이주민을 대상 으로 한 ‘체류 안정화 조치’를 논의한다. 이를 통해 체류 안정화 조치와 관련된 기존의 논의와 실천에서 좀처럼 다뤄지지 않은 ‘사회적 성원권’ 개념의 중요성을 환기하고, 이를 토대로 비정규 체류 이주민의 체류권에 대한 법적 인정의 필요성을 주창한다.

Fungi that infect mushrooms and cause diseases are called mycoparasitic fungi. Understanding the diversity of mycoparasitic fungi in wild mushrooms is important for the mushroom industry, as they can parasitize cultivated mushrooms. However, few studies have been conducted on the diversity of mycoparasitic fungi in wild mushrooms in South Korea. Upon surveying mushroom flora, we found a mycoparasitic fungus and analyzed its strain using molecular phylogeny and morphological examination. The strain was identified as Sepedonium laevigatum, which is an unrecorded species in South Korea. In this study, we described the cultural and microscopic characteristics of this strain of fungus.

In his Liberation Day speech, President Yoon Suk-yeol of South Korea pointed out that he would like to improve Korea-Japan relations towards a common future. However, a thorn in the relation between Japan and South Korea has been the unresolved issue of the so-called comfort women who had been forced to serve as sex slaves for the Japanese army between 1932 to 1945. The case of the comfort women raises many legal questions. On December 28, 2015, the Japanese and Korean government reached an agreement that aims to resolve the decades-old problem. The so-called 2015 Agreement gave new impetus to the debate over the legal responsibility of the Japanese government under international law. The most relevant issues and subsequent legal developments will be discussed in the following article.

오대산국립공원 내 뱀류 로드킬의 발생 경향 파악 및 예방을 위하여 2006-2017년 사이 공원 내에서 발생한 뱀류 로드킬 자료를 확보 및 분석하였고, 잠재적 발생지 예측을 위하여 종분포모델을 제작하였다. 연구기간 동안 뱀류 로드킬 은 600m 대의 양쪽 환경이 산림-수계인 도로에서 가장 많이 발생하였다. 모델링 결과에서 뱀류 로드킬 발생 가능성은 고도 700m 이하의 하천과의 거리가 25m 부근인 완만한 경사의 도로의 로드킬 발생확률이 높게 나타났다. 국립공원 내 주요 로드킬발생 예측지역은 국도 6호선 도로 위 공원 남쪽 경계로부터 약 2.2㎞ 지역과 약 11.7㎞ 지역이, 지방도 446호선 도로 위 공원 남쪽 경계로부터 약 3.44㎞ 지역이었다. 본 연구결과는 해발고도 700m 이하 수계와 인접한 도로 주변에 우선적으로 대체 일광욕 장소, 생태통로 및 도로의 유입을 막는 울타리의 설치가 산림에서 뱀류 로드킬을 줄이는 효과적인 방안이 될 것을 제시한다.

For the geological risk assessment of deep-depth underground condition by excavation work or tunneling, since rocks and geologic structure of each country is different, it is necessary to objectify or classify quantitatively deep-depth underground risk evaluation in accordance with Korean geologic characteristics. It could be summarized major factors of rock failure and underground space deformation by geological and geotechnical features as geologic structures, overburden, rock mass characteristics, groundwater, high stress and additional categories. Induced main factors that could be identified and predicted intermediate to deep-depth underground risk through literature investigation and analysis study on research trend related to the underground geological engineering. In order to assessment the risk of rock mass excavated from 100 m or more to several kilometers deep below the ground are classified into about 19 factors, and can be divided into 6 categories. Using these risk factors as basic data, weights for each factor for each category can be set, and further, the risk of excavated rock mass can be calculated.
