김희선,강문일,변정옥,한동운 한국수의공중보건학회 2002 예방수의학회지 Vol.26 No.4
경기, 강원, 충청, 경상 그리고 전라지역 에서 225마리의 들쥐를 포획하였더니 Apodemus agrarius coreae가 200마리로 전국적인 분포를 보였고, Apodemus peninsulae peninsulae는 25마리로 강원, 경상 및 전라지역에서만 포획되었다. 전기영동법을 이용하여 이들 두 종에 대한 간장 조직에서 조사하였던 G6PDH, ADA, PEP-A, PEP-B, AAT, SOD, LDH, MDH, PNP, GAPDH 등 10종 모두가 검출되었다. 등줄쥐에서는 전기영동분석 결과 32종의 표현형이, 흰넓적다리붉은쥐에서 8가지가 검출되었다. 두 종의 locus의 평균 유전학적인 다양성은 0.130으로 나타났고, 유전학적인 차이는 0.100~0.600으로 상대적인 차이를 보였으며, 등줄쥐는 0.150~0.398사이에 네 개의 집단으로 구분되었던 반면 흰넓적다리붉은쥐는 0.100~0.275의 차이로 확인되었다. 경기지역의 안성, 여주 그리고 전라지역의 완주에서 포획된 등줄쥐를 제외하고는 지역에 따라서 6~11개의 조직내 효소 표현형이 중복되어 있었다. 흰넓적다리붉은쥐 역시 한 가지 이상의 표현형이 있었고 이들은 지역적인 차이를 보였으며, 등줄쥐와 조직내 효소형과 중복되어 있었다. Two hundred of Apodemus agarius coreae and twenty five of Apodemus peninsulae peninsulae were caught from Kyonggi, Kangwon, Chungchong, Jeolla and Kyongssang provinces across the country. Isoenzyme patterns were analyzed by gel electrophoresis with liver homogenates of A. a. coreae and A. p. peninsulae. Using 10 enzyme systems, 32 electrophoretic types (ETs) were identified from two species of Apodemus including 8 ETs from A. p. peninsulae with genetic diversity per locus between 0.00 and 0.54 (mean 0.13). Genetic distances among ETs of A. a. coreae and A. p. peninsulae was between 0.100 and 0.600. Thirty two ETs of both species of Apodemus were classified to four major groups with genetic distance from 0.150 to 0.398. Eight ETs of A. p. peninsulae were grouped into four subgroups with genetic distance from 0.100 to 0.275. All ETs of A. p. peninsulae were belong to those of A. a. coreae with enzymatic variation. There was only one ET in A. a. coreae from Ansong an Yoju counties in Kyonggi and Wanju county in Jeolla province. However, all samples collected from the rest were identified to have 6 to 11 ETs on local enzymatic variance. Enzymatic overlap between both species was confirmed with at least one ET depending on the sites of collection.

In order to investigate chemical componets and minerals of edible mushrooms in Korea. Measurements were made using the techniques of Atomic Absorption Spectrophotometry. The results could be summarized as follows; Moissture contents of mushrooms were 6.0-11. 5% and crude ash were 5.8-9.2g/100g (dry base) The contents of K, Mg, Na, Fe, Ca, 7u, and Zn were 775-3250, 90.0-225.0, 9.5-205.0, 7.5-242.0, 2.3-110.0, 0.8-40.0 and 5.0-22.5 mg/100g respectivelly in the various kinds of Auriculania judas(Fr) Qual and Gryophore esculents were in higher value than the other mushrooms. The Cr, Mn, Pb and Cd contents were trace or not detected in mushrooms.

Many recent research reported that men, different from the past, want to represent their individualities through clothing and become important shoppers. The market for men is gradually extended. In this study, a well known relationship between clothing values and brand orientation were tested for male consumers. Data from 334 adult male consumers living in a metropolitan area were collected and analyzed. Results indicated that male consumers with various demographic characteristics such as age, marital status, income, and clothing expense showed different level of clothing values. Regression analysis results indicated that among hedonic clothing value factors, confidence in clothing and fashion orientation had significant influence on brand loyalty. Among utilitarian factors symbolic values expressed through clothing had a strong influence on brand loyalty of male consumers.

Background : The reported incidence of early gastric cancer located in the upper portion of the stomach has been increasing with the recent advances in its diagnosis and screening. Recently, we have successfully performed laparoscopic assisted proximal gastrectomy and gastric tube reconstruction without pyloroplasty on three patients with early gastric carcinoma localized to the upper third of the stomach. We describe our modification of this procedure in this report. Method : After creating an surgical pneumoperitoneum, the stomach was mobilized using laparoscopic coagulating shears. Upper half of the greater curvature and three-quarters of the lesser curvature were then dissected along with regoinal D2 lymphadenectomy. This was followed by a 5 cm, longitudinal mini-laparotomy in the upper abdomen, and the construction of the exteriorized stomach with a gastric tube measuring 20 cm long and 4 cm wide. Reconstruction with an esophagogastrostomy was performed using a circular stapler. Result : No post-operative morbidity or mortality was observed in this small series of patients. The average operative time was 250 minutes (range 220-300 minutes), and the average blood loss was 150 ml (range 90-180 ml). The mean number of lymph nodes harvested during these laparoscopic proximal gastrectomies was 24 nodes (range 22-25 lymph nodes). The average postoperative hospital stays was 7.5 days (range 7-8 days). Conclusion : Our technique of laparoscopic assisted proximal gastrectomy and gastric tube reconstruction without phloroplasty offers a minimally invasive technique with the potential of impoving the post-operative quality of life patients with an early-stage proximal gastric cancer.

A focusing grating coupler (FGC) was not fabricated by the 'Continuous Path Control'writing strategy but by an electron-beam lithography system of more general exposure mode, which matches not only the address grid with the grating period but also an integer multiple of the address grid resolution (5 nm). To more simplify the fabrication, we are able to reduce a process step without large decrease of pattern quality by excluding a conducting material or layer such as metal (Al, Cr, Au), which are deposited on top or bottom of an e-beam resist to prevent charge build-up during e-beam exposure. A grating pitch period and an aperture feature size of the FGC designed and fabricated by e-beam lithography and reactive ion etching were ranged over 384.3 nm to 448.2 nm, and 0.5 $\times$ 0.5 mm$^2$area, respectively. This fabrication method presented will reduce processing time and improve the grating quality by means of a consideration of the address grid resolution, grating direction, pitch size and shapes when exposing. Here our investigations concentrate on the design and efficient fabrication results of the FGC for coupling from slab waveguide to a spot in free space.
