The purpose of this paper is to trace the architectural origin of the Bosung College Library (1935~37), which is currently used as Graduate School Building of Korea University. So far, numerous books have repeatedly described that the library was modelled on a Duke University library, but without any serious consideration. Through literature review, field-trip and archives investigation, this research discovered new critical facts concerning the origin of the building. First, Dong-Jin Park, the architect for Bosung College, saw a photograph of the Duke library in a Duke University catalog possessed by Chun Suk Auh, Professor of the college at that time. Second, the Duke library that he saw in the catalog, which might possibly be Bulletin of Duke University (Feb. 1931), is certainly the present Perkins Library (1930) in Duke University West Campus. Third, the architect probably referred not only to the library but also to other Duke buildings such as School of Medicine and The Union, of which photographs were also published impressively in the Bulletin. Although the Bosung College Library was inspired by the Duke buildings, however, it is undoubtedly a creative design work by the architect Park. Arguably, these findings broaden our view of Korean architectural history in the modernization period, and it is more than a confirmation of just one building's origin.

Genetic diversity of 45 tea accessions from Korea, Japan, China and Taiwan was investigated by using RAPD analysis. Out of the eighty primers screened, twenty primers generated 99 polymorphic bands with a polymorphic rate 87.0%. The size of the amplified fragments ranged from about 3,138 bp to 520 bp. By cluster analysis, all of the 45 accessions can be grouped into five groups. Over 90% of the 32 Korean accessions belonged to group II, III, IV and V. Moreover, newly developed Korean cultivars (accession no. 13, 14 and 15) belonged to very different group compared with any other Korean accessions. Among the Korean accessions, the minimum genetic similarity 0.500 was obtained between accession no. 17 and 37 and the largest genetic similarity 0.912 between no. 20 and 21.

A new single glutinous maize hybrid "Huin Chal 1" was developed at the Genetics and Breeding Lab., Dept. of Agron., College of Agriculture, Chungnam National University. Parents for the hybrid were all derived from Korean indigenous maize lines which were collected in 1980s. One of the parental inbred lines was originated from Bosung, Chonnam province and other inbred line was from Jewon, Chungbuk province. Both inbreds were developed by ear-to-row selection method through selling and named as Bosung and Jewon, respectively. Performace tests for the hybrid which was produced between Bosung and Jewon have been conducted five times including one test at Crop Experiment Station, Rural Development Administration. From the previous performance tests, the hybrid was recognized as high yielding hybrid with good agronomic characteristics and we named the hybrid as Huin Chal 1., and hereby we report the agronomic characters of the newly developed hybrid.

This is the report of sacroiliac luxation in a Holstein-Friesian cow, describing the progression of the sacroiliac luxation from the onset of its development with changes in estradiol (E2) and serum chemistry. The high estrogen concentration was assumed to be a predisposing factor of the disease that relaxed the pelvic muscles and a secondary slippery finally caused the sacroiliac luxation. The E2 was present at levels four times higher in the cow with sacroiliac luxation (167 pg/mL) than in normal cows. Above normal levels of creatinine kinase, aspartate aminotransferase, and lactate dehydrogenase were also observed in cow with sacroiliac luxation.

최근 수정범용토양유실공식을 활용한 토양침식 연구가 활발히 진행중에 있으나, 실측자료와의 비교가 어렵기 때문에 계산된 결과를 정량적으로 검증하지는 못하였다. 본 연구에서는 RUSLE 모형을 구성하고 있는 인자들을 GIS 격자분석기법으로 분석하였으며, 특히 1:250,000 개략토양도를 주로 활용하였던 기존의 연구와 달리 1:25,000 정밀토양도를 활용한 토양침식인자를 제시하였다. 그리고 RUSLE 모형으로 계산한 토양침식량의 검증을 위해 보성강 유역의 비퇴사량 실측자료를 이용하였으며, 토양도의 축척을 고려한 결과 1:25,000 개략토양도의 경우는 120m의 해상도가 적합한 것으로 평가되었고 1:25,000 정밀토양도를 고려한 경우는 150m 해상도가 적합한 것으로 평가되었다.

The purpose of this study was to compare the effect of solid-state fermentation on soybean using three microbial strains under four different fermentation times. Soybean was fermented for 12, 24, 36 or 48 hours with highly proteolytic microbes, either Bacillus amyloliquefaciens (BA), B. subtilis (BS), or B. subtilis var. natto (BN), and levels of total protein concentration, protein distribution, and antioxidant activity were analyzed. Total protein was highest in the BS 12 h group (9.21 ㎍·µL^-1) and lowest in BN 48 h (6.80 ㎍·µL^-1), respectively (p < 0.001). Furthermore, three microbes decomposed large molecular weight proteins as well as major allergens of soybean such as β-conglycinin, Gly m Bd 30K, and glycinin. Each treatment group showed the highest degradation rate at 48 h fermentation and among the three microbes, BS showed a relatively higher degradation rate. The radical scavenging ability, known as an indicator of antioxidant activity, showed a significant increase in all treatment groups except BA 24 h. The results from this study suggest that protein concentration, and degradation and antioxidant activity were affected by different types of microbial trains and fermentation period and that B. subtilis fermentation might be the most effective way to increase nutritional and functional properties of soybean.

Purpose: The aim of this study was to explore the patients' perspectives on nursing students' clinical practices in the wards, and to investigate their willingness for allowing students to practice on them. Methods: This was a descriptive study. 116 inpatients were recruited from the S University Hospital. A 60-item questionnaire was applied to collect the data. The participants were 19 years and older with sound judgement, and were not in special or intensive care units. Data analysis was done in SPSS/WIN 22.0 using descriptive statistics, Fishers exact test, and the ANOVA test. the participant answered to questionnaire from April 29th 2016 to May 10th. Results: 40 participants (34.5%) stated they would allow students' practice, while 72 (61.2%) said they would allow only under staff supervision. 5 participants (4.3%) stated they would not allow whatsoever. The 3 most allowed were emotional support, oral care, and vital signs measurement while the 3 least allowed were gastric feeding, intravenous catheterization, and urinary catheterization. Conclusion: Patients were more inclined to allow students to practice on them when a member of the medical team was present. A fair number of participants said they would be more inclined to allow students' practice if they felt the student was competent; hence, reinforcing simulation sessions is vital in enhancing students' competency and ultimately practice allowance.
