Albinism, characterized by absence or lack of pigmentation from the hair, skin, hooves, nasal region and the eyes is rarely seen in cattle in Korea. A 15-day old calf, approximately weighing 28 kg has been conspicuously distinct from the rest of 40 herds of cattle raised in Sunchang country because of its white coat color, white muzzle and hooves and eyes with light pinkish iris. The calf was born of Korean indigenous cattle with no previously reported history of albinism since inception of the farm for over a decade period. It was assumed as a form of recessive genetic disorder. This observation was documented to present occurrence of albinism in cattle in Korea.

부모의 당뇨병 가족력과 가족력이 있는 한국 성인 남성을 대상으로 대사증후군의 인자와 관계를 파악하고자 한다. 자료는 질병관리본부에서 실시한 국민건강영양조사 제5기 1차년도(2010년) 자료를 이용하였다. 대상자수는 총 2,045명으로 하였다. 통계분석은 복합표본설계 일반선형 회귀분석을 이용하여 분석하였고, 통계적 유의성은 p<0.05로 하였다. 일반적 특성을 보정하여 다변량 분석을 한 결과 아버지가 가족력이 있는 경우 허리둘레(wc)는 2.5cm, 공복혈당(glu)의 경우 9.6mg/dL, 중성지방의 경우 41.6mg/dL 증가하였다. 어머니가 가족력이 있는 경우 허리둘레(wc)는 2.4cm, 공복혈당(glu)의 경우 15.4mg/dL, 중성지방의 경우 27.2mg/dL 증가하였다. 결과적으로 아버지가 당뇨병 가족력이 있는 자녀의 허리둘레, 공복시 혈당, 중성지방과 어머니가 가족력이 있는 자녀의 허리둘레와 공복시 혈당의 수치가 유의하게 높게 나타난 것을 알 수 있었다.

멸종위기 담수어인 모래주사의 종 보존을 위한 기초자료를 얻기 위해 난발생 및 초기생활사를 연구하였다. 2012년 5월 1일 전북 임실에서 포획된 성어를 이용하여 인공 수정시켰으며, 수정란은 구형의 분리침성란에 난경은 $1.8{\pm}0.14mm$였다. $23^{\circ}C$의 수온에서 29시간 후에 부화하였으며, 부화 직후 전기자어의 크기는 $2.2{\pm}0.48mm$였다. 부화 후 4일째 난황을 모두 흡수하여 후기자어기에 진입하였으며, 전장은 $3.6{\pm}0.55mm$였다. 20일이 지나자 지느러미 기조수가 정수가 되어 치어기로 이행하였으며, 전장은 $6.5{\pm}0.77mm$였다. 부화 후 60일이 지나자 두부와 체측에 나타나는 반문이 성어와 유사해졌으며, 전장은 $24.4{\pm}1.71mm$에 달하였다. 모래주사의 난발생 과정 및 초기생활사를 모래무지아과 어류들과 비교한 결과 수정란의 부화시간은 비교적 빨랐으며 부화 직후 전기자어의 크기도 작았다.

Exposure to lead, particularly at chronic low-dose levels, is still a major public health concern. The present study is aimed to evaluate the blood lead levels in populations resident in some abandoned mine areas of Chungbuk, Korea. Eight hundreds and sixty-six subjects who reside in abandoned mine area located in Chungbuk, Korea, were enrolled this study. We evaluated the blood lead level according to the age, gender, and working history in mines. For statistical analysis, SPSS ver 12.0 was used. The geometric mean blood lead levels was $2.93\;{\mu}g/{\ell}$ and nobody showed levels over the guidelines of WHO. Ex-smokers and current-smokers showed significantly higher blood lead levels compared to that of non-smokers. The blood lead levels in individuals with a history of working in a mine was higher than those in individuals without such histories. The populations resident in some Chungbuk abadoned mine area showed low levels of lead in blood. This suggest that lead poisoning might not be induced by abandoned mine in Chungbuk, Korea.

The NISS (Near-infrared Imaging Spectrometer for Star formation history) onboard NEXTSat-1 have successfully developed by KASI. The capability of both imaging and spectroscopy is a unique function of the NISS. At first, it have realized the low-resolution spectroscopy (R~20) with a wide field of view of $2{\times}2deg$. in a wide near-infrared range from 0.95 to $2.5{\mu}m$. The major scientific mission is to study the cosmic star formation history in local and distant universe. It will also demonstrate the space technologies related to the infrared spectro-photometry in space. Now, the NISS is ready to launch in late 2018. After the launch, the NISS will be operated during 2 years. As an extension of the NISS, the SPEHREx (Spectro-Photometer for the History of the Universe Epoch of Reionization, and Ices Explorer) is the NASA MIDEX (Medium-class Explorer) mission proposed together with KASI (PI Institute: Caltech). It will perform the first all-sky infrared spectro-photometric survey to probe the origin of our Universe, to explore the origin and evolution of galaxies, and to explore whether planets around other stars could harbor life. Compared to the NISS, the SPHEREx is designed to have much more wide FoV of $3.5{\times}11.3deg$. as well as wide spectral range from 0.75 to $5.0{\mu}m$. After passing the first selection process, the SPHEREx is under the Phase-A study. The final selection will be made in the end of 2018. Here, we report the status of the NISS and SPHEREx missions.

In this study, we investigated advertisements in Dong-a newspaper about gynecological drugs between 1920 and 1945 and analyzed the awareness of women's health and disease during the Japanese Colonial Rule. The advertisements included leukorrhea, oligomenorrhea, dysmenorrhea, feeling of cold, sterility, hysteria, and sexually transmitted infection and identified inattentive menstruation, improper intercourse, poor pre- and post-natal care as the cause for illness. This study includes the following limitations; it only analysed advertisements from Dong-a newspaper, and most of the drugs were manufactured in Japan and might not accurately reflect the health and disease of Korean women. Suggested future studies may include analysis of institute magazine and Japanese news advertisements during this period.

국사편찬위원회는 역사 연구의 자료가 되는 기록인 사료의 중심 수집기관으로 사료조사수집 활동을 통한 성과물을 이용자에게 제공하기 위한 수집사료 관리시스템을 개발하고 있다. 사료는 기록물의 특성을 가지고 있어 출처주의, 계층목록과 같은 기록물관리체계를 따르지만 실제 업무흐름은 도서관업무와 유사하다. 국편이 목표로 하는 수집사료 관리시스템은 전자사료관시스템과 전자도서관시스템의 통합된 형태가 된다. 본 연구는 국사편찬위원회의 사례를 중심으로 수집사료 관리시스템의 개발과 시스템의 성공적인 운영을 위해 고려해야 할 사항들을 제안하고 있다.

This thesis aims to study the founding process and operation of the prefectural archives of Japan and to put that knowledge to the founding regional archives in Korea. Now 28 among 47 Prefectural Governments in Japan have founded and operated the prefectural archives. While Kyoto Prefectural Library and Archives, Nagano Prefectural Museum of History, Gifu Prefectural Virtual Museum of History, The Archives of Hyogo Prefectural Government, Ibaraki Prefectural Museum of History and Hukushima Prefectural Archives are on the type of Prefectural Museum of History, the rest of them are on the type of Archives. The Prefectural Museum of History in Japan has a complex function as the museum, the library, and the archives. But the Prefectural Museum of History seems to be a sort of transient phenomenon to Archives. The reason which Prefectural Museum of History can not develop into the Archives is not so much owing to financial difficulties as lack of understanding on the function of Archives. The thesis shows founding process of each prefectural archives. Especially, the case study on the Kanagawa Prefectural Archives, Okinawa Prefectural Archives was arranged by the detailed data investigation. Comparing with other prefectures, these three prefectural archives have a system in the collection and arrangement process of current official records, paleography and many other materials, and construct records management system with institutionalizing accession, arrangement, and opening of official records by regulations, rules and so forth. But because of historical background and character in each region, the difference may exist in the founding process of three prefectural archives. Before central archival institution, National Archives of Japan, is founded, the prefectural archives have been founded at each region and they have gained relatively independent status so that decentralism in the system of managing records could be possible. And the private historical organizations had many influences on the founding process of National Archives of Japan. Of course the Japanese Archives system may have many differences from Korean regional archives. While Japan established Archives institute for itself with localism, Korea has not settled the system of self-government still. Moreover, financial difficulties on founding regional archives and lack of understanding of the Archives remained in Korea. And yet with regard to the founding regional archives in Korea, the case of operation and founding process of prefectural archives of Japan may be of great value.

Korea Superconducting Tokamak Advanced Research (KSTAR) has a helium refrigeration system (HRS) with the cooling capacity of 9 kW at 4.5 K. Main cold components are composed of 300 tons of superconducting (SC) magnets, main cryostat thermal shields, and SC current feeder system. The HRS comprises six gas storage tanks, a liquid nitrogen tank, the room temperature compression sector, the cold box (C/B), the 1st stage helium distribution box (DB#1), the PLC base local control system interconnected to central control tower and so on. Between HRS and cold components, there's another distribution box (DB#2) nearby the KSTAR device. The entire KSTAR device was constructed in 2007 and has been operated since 2008. This paper will present the maintenance result of the KSTAR HRS during the campaign and discuss the operation record and maintenance history of the KSTAR HRS.
