New Korean lumbricids are described: Eisenia gaga Blakemore sp. nov. from remote Gageodo Island and E. sindo Blakemore, sp. nov. from an island at Incheon. Both are comparable to Eisenia koreana (Zicsi, 1972) from near Pyongyang, North Korea. A remarkable yet previously unrecognized similarity to American earthworm Eisenoides carolinensis (Michaelsen, 1910) is discussed, but synonymy is rejected on tenuous morphological grounds (form of nephridial vesicle bladders) with taxonomy supported by objective molecular data (mtDNA cytochrome c oxidase subunit 1 barcodes).

연구는 북한지역의 표토침식량 산정을 위하여 토양침식을 유발하는 강우침식인자를 산정하고 장기간에 걸친 경향성을 분석하기 위한 연구로서, 대상지역은 평양 관측소 지점의 1981~2014년의 강우자료를 이용하였다. 가용한 북한지역의 강수량은 월강수량이기 때문에, 강우침식인자의 산정은 수정 IAS 지수를 이용한 추정방법과 연강수량을 이용한 추정방법을 적용하였다. 연강우침식인자에 대한 경향성 분석결과 평양지점의 장기간에 걸친 연강우침식인자 값에 대한 뚜렷한 경향성은 발견되지 않는 것으로 나타났다.

The purpose of this study is to identify the supply status and planning trend of North Korean housing through analysis on the North Korean architecture specialized media data. The flat composition is changing and the living room is becoming the center of the houses. Also, in the urban areas, the standard apartment type is four apartments in a row and the plan form is getting diversified into circle type, Y type, and irregular type. On the other hand, in the rural areas, two houses in a row and single house are typical and the change in planning scale and space structure are not substantial. Since the 2000s, design changes have been made to emphasize the third dimensional structure of buildings such as the elliptical houses and L-shaped houses. Furthermore, 8~10 households are located on one floor which leads to the tendency of the building enlargement. In terms of house size, a square concept was introduced to replace the initial 2~3 room concept and the basic module of the room planning the 3 room house based on $3m{\times}3m$. However, there seems to be no standard house size, and the house size may differ depending on the social classandregion. In the early 1980s, when there was focus on the apartment complex construction, the high-rise apartment buildings of 30~40 floors was planned. However, during the Pyongyang redevelopment project, apartments of more or less than 10 floors were built and row-houses of more or less than 4 floors were built. In terms of the complex scale, a lot of small complexes of around 300 households are emerging after 2010. The construction projects are mainly limited to specific regions such as Pyongyang and Samjiyeon, and also limited to specific classes such as the workers and soldiers initially and the scientists lately. In addition, living boundary composition and ancillary facilities for sufficient green area ratio securement and the people of North Korea are maintained consistently. In recent years, the specialized floor planning such as solar house and the house for the disabled people, framework houses for redevelopment business, and multi-storied house construction technology are also emerging.

일제 강점기 조사 미등록 유물 정리사업의 일환으로 수행한 낙랑 고분인 평양 남정리 53호분에서 출토된 토제칠이배와 칠반에 대한 과학적 조사내용이다. 남정리에서 출토된 유물은 소지가 목심이 아닌 토제라는 것과 토제칠이배와 토제칠반, 토제칠안이 공반되어 출토되었다는 것이 크게 주목할 만하다. 그중 이번 분석에서 토제칠이배와 토제칠반은 적색 안료 또는 흑색 안료를 칠과 함께 사용하였음을 알 수 있었다. 분석 결과, 적색 안료는 진사(HgS)로 확인되었고 흑색 안료는 탄소계통의 안료로 추정되었다.

Radar remote sensing is appropriate for rice monitoring because the areas where this crop is cultivated are often cloudy and rainy. Especially, Synthetic Aperture Radar (SAR) can acquire remote sensing information with a high temporal resolution in tropical and subtropical regions due to its all-weather capability. This paper analyzes the relationships between backscattering coefficients of rice measured by RADARSAT-2 SAR and growth parameters during a rice growth period. And we applied the relationships to crop monitoring of paddy rice in North Korea. As a result, plant height and Leaf Area Index (LAI) increased until Day Of Year (DOY) 234 and then decreased, while fresh weight and dry weight increased until DOY 253. Correlation coefficients revealed that Horizontal transmit and Horizontal receive polarization (HH)-polarization backscattering coefficients were correlated highly with plant height (r=0.95), fresh weight (r=0.92), vegetation water content (r=0.91), LAI (r=0.90), and dry weight (r=0.89). Based on the observed relationships between backscattering coefficients and variables of cultivation, prediction equations were developed using the HH-polarization backscattering coefficients. Concerning the evaluation for the applicability of the LAI distribution from RADARSAT-2, the LAI statistic was evaluated in comparison with LAI distribution from RapidEye image. And LAI distributions in Pyongyang were presented to show spatial variability for unaccessible areas.

We have analyzed 42 research papers regarding on the solar astronomy written by North Korea scientists to investigate the current status of astronomical activities in North Korea. The papers are surveyed from the 'Bulletin of Astronomy', the 'Physics', the 'Bulletin of Academy of Science', and the 'Natural Science' in North Korea, and SCI journals. In addition, we refer to the presentation material announced in the 2015 IAU by director of Pyongyang Astronomical Observatory (PAO) and the 2013 OAD/IAU reports. We have analyzed the papers statistically according to three criteria such as research subject, research field, and research members. The main research subjects are the sunspot (28%), observation system (21%), and space environments (19%). The research fields are distributed with data analysis (50%), numerical method (29%), and instrument development (21%). There have been 25 and 9 researchers in the solar astronomy and space environment, respectively since 1995. North Korea's solar research activities were also investigated in three area: instrument, solar physics, and international research linkage. PAO has operated two of sunspot telescope and solar horizontal telescope for spectroscopy and polarimetry, but there is no specific information on solar radio telescopes. North Korea has cooperated in solar research with Europe and China. We expect that the results of this study will be used as useful resource in supporting astronomical cooperation between South and North Korea in the future.

평양 여명거리의 70층 초고층 아파트는 불과 75일 만에 지상 골조공사가 완료되어 구조적 안전성에 의문이 제기됐다. 본 연구는 이 의문에 대한 답을 구하여 향후 남북 건설협력에 일조하기 위해 진행됐다. 구글어스와 북한 측 자료를 분석한 결과, 몇 가지 조건 아래에서 얕은기초의 적용, 콘크리트 강도와 양생기간을 포함한 공사속도, 그리고 적어도 2022년 5월 현재까지는 구조적 안전에 문제가 없었음을 추정할 수 있었다. 이로써, 북한식 초고층 아파트 건축공사 방식이 남한 기준으로도 이해될 가능성을 확인했고, 이는 향후 북한에서 남북 건축사업 합작 시 북한식 건축공사의 적용과 남한 자원의 최소 이동을 가능케 하여 성공적인 합작 건설사업 수행에 도움이 될 수 있다.

군사적인 공격을 하지 않는다는 약속과 함께 핵무기와 미사일을 개발하지 않는 조건으로 원전을 통한 전력 생산에 도움을 주겠다고 약속하는 것이 북한이 이웃나라에 대한 핵 위협을 중단할 수 있는 명분을 제공하고, 미사일이나 그 밖에 교역이 금지된 군수품의 수출을 중단하는 데 대한 확실한 보상책이 될 수 있을 것이다. 건설적 개입이야말로 한반도에 평화를 정착시키고 나아가 북한 인민들에게 자유를 가져다주는 데 결정적인 정책이다. 트럼프 대통령에게는 북한과 'Atoms for Peace' 협상의 물꼬를 트는 과정에서 핵전쟁의 위협을 줄임으로써 인류애를 실현시킬 수도 있는 기회가 있다. CIA는 현재 30개 이상의 나라가 핵무기를 개발할 수 있는 기술적인 능력을 보유하고 있다고 추정하고 있는데, 그 가운데 단지 9개 나라만 핵무기를 개발할 수 있게 허용되어 있다. 요컨대 70년이 넘는 세월 동안 핵능력을 보유한 나라들이 핵무기를 실전에 사용하지 않는 데 성공한 것이다. 따라서 지금 우리에게 가장 필요한 것은 'Atoms for Peace'라는 정책 비전을 한반도 문제의 해결 방식에 적용하는 한편 계속 확대시켜 나가는 것이다.

We analyse the map of the west capital Pyongyangbu of Old Korea(AD 920) by topological method and geometrical method and compare it with the map of North Korea Pyongyang. By the analyse of the map we find the real place of the old map. The analysing and finding the real place of the old map is a very good example of geometry education. Many Koreans had learned and recognized that Old Korea(AD 920) was a small country located in the south part of Ablok river. But, after reading this paper they change their old recognitions and they take prides in Great Old Korea.

Cardot(1904) first reported 98 Korean mosses, which were collected from Busan, Gangwon Province, Mokpo, Seoul, Wonsan and Pyongyang by Father Faurie in 1901. Thirty-four of these species were new species to the world. However, eight of these species have been not listed to the moss checklist of Korea before this study. Thus, this study complies the literature including Korean mosses, and lists all the species there. As the result, the moss list of Korea is updated as including 775 taxa (728 species, 7 subspecies, 38 varieties, 2 forma) arranged into 56 families and 250 genera. This list include species that have been newly recorded since 1980. Brachythecium is the largest genus in Korea, and Fissidens, Sphagnum, Dicranum and Entodon are relatively large. Additionally, this study cites specimens collected from Jeju Island, Samcheok, Gangwon Province, and Socheong Island, and it is possible to confirm the distribution of 338 species in Korea.
