Precision thin film resistors using evanohm R alloy were fabricated by do magnetron sputtering method. The physical and electrical properties of the resistors were studied after treatment of thermal annealing. The crystallization of the film was increased as the annealing temperature increase. Diffusion and oxidation of Cr and Al elements were occurred into the film surface. The minimum TCR values of 10.46 ppm/$^{\circ}C$ and 10.65 ppm/$^{\circ}C$ were measured at the annealing temperatures of $200^{\circ}C$ and $300^{\circ}C$, respectively. We are conducting additional studies to improve characteristics of our resistors for practical device application.

이영화,김용함,Lee, Young-Hwa,Kim, Yong-Hamb 한국전기전자재료학회 2008 전기전자재료학회논문지 Vol.21 No.10

We report on the development of transition edge sensors for x-ray detection. The sensor technology was based on the fabrication of a superconducting film on a thin membrane. A bilayer of a superconductor, Ti, and a noble metal, Au, was e-beam evaporated on a micromachined SiNx. Another Au layer was evaporated on the two side edges of the bilayer in order not to be affected by structural imperfections at the boundaries. With the method described in the present report, the superconducting transition temperature of the device was consistently achieved to near 80 mK with a sharp transition. The energy spectrum ueasured with the device provided 37 eV FWHM for 5.9 x-rays. We also discuss the design and fabrication considerations as well as the performance of the device in detail.

We are developing a sensitive gamma ray spectrometer based on superconducting transition edge sensors. The detector consists of a small piece of high purity Sn as an absorber and a Ti/Au bilayer as a temperature sensor. It is designed to measure the thermal signal caused by absorption of gamma rays. The mechanical support and the thermal contact between the absorber and the thermometer were made with Stycast epoxy. The bilayer was formed by e-beam evaporation and patterned by wet etching on top of a $SiN_X$ membrane. A sharp superconducting transition of the film was measured near 100 mK. When the film was biased to the edge of the transition, signals were observed due to single photon absorption emitted from an $^{241}Am$ source. The measured spectrum showed several characteristic peaks of the source including 59.5 keV gamma line. The full with at half maximum was about 900 eV for the 59.5 keV gamma line. The background was low enough to resolve low energy lines. Considerations to improve the energy resolution of the gamma ray spectrometer are also discussed.

본 연구는 유채 꽃가루 분말의 영양성분 분석과 파쇄한 꽃가루 분말을 이용하여 효모 배양용 액체배지와 고체배지를 제조하여 효모 배양효율을 분석하였다. 유채 꽃가루 분말(100 g)은 탄수화물 58.9 g, 단백질 20.8 g, 지방 4.1 g, 회분 2.5 g 및 수분 13.7 g으로 구성되었다. 당질 중에서는 Fructose(13.7 g), Glucose(11.1 g)와 Sucrose(6.6 g), 미네랄 중에서는 K(606.7 mg)와 P(603.3 mg) 함향이 높았다. 유리 아미노산은 Glutamic acid(2,482.4 mg), Aspartic acid(2,136.5 mg), Lysine(1,648.3 mg), 및 Leucine(1,631.1 mg) 순으로 많았다. 유채 꽃가루 분말을 단독 또는 NaCl을 첨가하여 액체배지 및 고체배지 제조하고 효모를 배양한 결과, 꽃가루 분말이 15 g/L 이상 함유된 액체배지는 효모 배양 후 건물중이 YPD 배지(대조구)에 비해 많았고, 꽃가루 분말의 농도 의존적으로 효모 건물중이 증가하였다. 또한 액체배지에 NaCl을 1~20 g/L 추가 시 배양된 효모의 건물중이 한층 더 증가하였다. 유채 꽃가루로 제조한 고체배지를 이용하여 효모를 배양(48시간)한 결과, 콜로니(colonies) YPD 배지와 유사하게 잘 자랐다. The aim of this study was to analyze nutritional compositions of rapeseed pollen granules and to determine the possible usage of pollen granules as a yeast culture medium. Rapeseed pollen granules (per 100 g) were consisted of carbohydrate 58.9 g, protein 20.8 g, fat 4.1 g, ash 2.5 g and water 13.7 g. And fructose (13.7 g), glucose (11.1 g), and sucrose (6.6 g) of sugars and K (606.7 mg) and P (603.3 mg) of minerals were highly contained. In addition, free amino acids such as glutamic acid (2,482.4 mg), aspartic acid (2,136.5 mg), lysine (1,648.3 mg), and leucine (1,631.1 mg) were present at a higher level. When liquid medium, which was made from cracked pollen granules (5, 10, 15, 20, 25, 30, and 40 g/L), was tested for yeast culture, liquid medium containing pollen granules over 15 g/L showed higher yeast growth than YPD medium (control). Liquid medium containing both cracked pollen granules (15 g/L) and NaCl (1 ~ 20 g/L) improved yeast growth than the liquid medium without NaCl. In addition, when yeast growth was tested on solid medium made from pollen granules (15 g/L) at $30^{\circ}C$ for 2 days, yeast colonies were equally well-formed like those grown on YPD medium. Overall, rapeseed pollen granules have potential properties on yeast growth and could be used as a primary source for yeast culture.

Culture becomes one of the core sources for national competitiveness and national economic Security in the 21st century. Korea government`s supports for developing contents industry with Korean traditional culture and cultural goods is the strategy to develop national competitiveness. Korean traditional paper is one of the most unique materials and represents its own culture. Cultural industry with traditional art might be the most valuable and produces high value-added products, although there are many factors to evaluate cultural value of the product. It means industries shall be connected with culture necessarily. Cultural goods with Korean traditional paper illustration has a significant meaning because it links paper and printing industry, art culture and marketing. When it merges its traditional and contemporary cultures, it will produce modem and international senses to develop a new visual language. If we create Korean design by comparing various kinds of information, and technology, coordination them with the attributes of exiting design and changing level based on Korean culture, we can create real `Design Korea`.

북한의 고대사 연구 동향

이영화(Lee Young-Hwa) 한국고대사탐구학회 2009 한국고대사탐구 Vol.3 No.-

본고는 북한에서 발간된 각종 학술지에 실린 고대사 논문을 추출하여 해방 후 60여 년 동안 북한 고대사의 연구 동향을 파악하고자 하였다 이를 위해 북한 역사학 내에서의 고대사 편제 방식과 각 학술지의 간행 연혁과 현황을 북한의 정치 변동과 관련하여 살펴본 후, 1,354편의 고대사 논문을 시대별ㆍ국가별로 분류하여 전체적 경향성을 분석하였다. 북한의 역사 논문 중 고대사 논문이 가장 높은 비율을 차지하여 북한 역사학이 가장 주력한 분야가 고대사이고, 고대사 논문 중에서는 고고학 논문이 절대 다수를 차지하고 있어 북한의 고대사 연구가 문헌보다는 유물ㆍ유적을 중심으로 진행되었음을 알 수 있었다. 국가별로는 고대사 논문 편수가 高句麗, 古朝鮮, 渤海의 순으로 나타났고, 시기로는 1980년대 후반 이후에 고조선ㆍ고구려ㆍ발해의 계승 체계가 완성되었음을 알 수 있었다. 북한의 고대사 연구는 권력 변동에 따라 몇 차례 파동을 겪었다. 1950년대 후반의 반종파투쟁, 1960년대 후반의 5.25교시, 1990년대의 檀君陵 발굴 등은 그때마다 북한의 고대사 연구 방향을 변화시켰다. 정권 초기에는 唯物史觀에 입각한 고대사 체계를 정립하는 진통을 겪었고, 1950년대 후반부터는 ‘주체사상’으로 재정립되는 과정을 거쳤고, 1990년대 이래는 ‘民族主義’로 고대사 체계를 재편성하는 과정을 거쳤다. 단군릉 발굴 이후 ‘大同江文化論’을 주장하고 결국 ‘김일성 민족론’으로 귀결되는 과정은 북한 고대사가 유물사관을 넘어 민족주의 일변도로 재구성되는 과정이었다. This research is analysis of papers of North Korea s ancient history published after liberation 1945. To this end, composition of the University, laboratory organization, and the Institute's organization in North Korea are analyzed. Especially noteworthy, research trends of North Korea's ancient history has closely associated with political change of North Korea. The study most focused on North Korea is ancient history. In addition, the center of North Korea's ancient history is an archaeologist. Research of the artifacts remains is even more important than literary research. Looking at the statistics of papers of ancient history, Goguryeo was the most research, the next Gojoseon, followed by the Bolhae was studied. The direction of study of ancient history has changed several times because of the establishment of the Juche idea. Initially, the materialism to clean up the ancient history had experienced pain, since the late 1950s, the Juche idea was to reconstruct ancient history. Dangunneng case of 1993 shows the process of ancient history to be composed of nationalism. After Dangunneng excavation, Taedonggang area was extensively excavated, and argued Taedonggangmunhwalon. So-called Taedonggangmunhwalon, Taedonggang area is the cradle of civilization and the oldest civilization.
