Background: Woori-Heukdon (KWH) is a Korean synthetic pig breed generated using Chookjin-Duroc (KCD), Chookjin-Chamdon (KCC), and their crossbreds. Currently, there is a severe lack of studies investigating the Korean breed populations including wild boars (KWB) throughout the genome. Objective: This study was performed to investigate the genetic characteristics of Korean pig populations at the genome-wide level. Methods: Using the SNP dataset derived from genotyped and downloaded datasets using the Illumina PorcineSNP60K BeadChip, we compared the genomes of 532 individuals derived from 23 pig breeds to assess the genetic diversity, inbreeding coefficient, genetic differentiation, and population structure. Results: KWB showed the lowest average expected heterozygosity (HE = 0.1904), while KWH showed the highest genetic diversity (HE = 0.02859) among Korean populations. We verified that the genetic composition of KWH, showing USD of 74.8% and KCC of 25.2% in ADMIXTURE analysis. In population structure analyses, KCC was consistently shown to be separated from other pig populations. In addition, we observed gene flow from Western pigs to a part of Chinese populations. Conclusion: This study showed that Korean native pigs, KCC have genetic differences in comparison with Chinese and Western pigs; despite some historical records and recent genetic studies, we could not find any clear evidence that KCC was significantly influenced by Chinese or Western breeds in this study. We also verified the theoretical genomic composition of KWH at the molecular level in structure analyses. To our knowledge, this is the first genomic study to investigate the genomic characteristics of KWH and KCC.

The stability constants of Co(II), Ni(II), Cu(II) ions with macrocyclic ligands containing nitrogen and oxygen donors such as 1, 15-diaza-3, 4:12, 13-dibenzo-5, 8, 11-trioxacycloheptadecane(NEOD), 1, 12, 15-triaza-3, 4 : 9, 10-dibenzo-5, 8-dioxacycloheptadecane(NDOE) have been determined by UV-VIS spectrophotometric method in DMSO. The order of complex stability constants of the transition metal ions with ligands is Co(II) < Ni(II) < Cu(II), the same as the natural order of stability published by Williams-Irving, and stability constants have been found to be effected by the chelate effect of macrocyclic ligands, so the order of ligands effect is NEOD < NDOE.

본 연구는 교육대학생의 자치활동 실태와 학생 의견을 바탕으로 교육대학에서 지향해야 할 자치활동의 방향을 모색하고, 건전한 학생활동에 대한 지원 및 지도 방안을 제시하는 데 목적이 있다. 본 연구를 위해 수집된 자료는 SPSS WIN 9.0 통계 패키지 프로그램을 사용하여 분석하였다. 학생 자치활동의 실태를 알아보기 위한 주요 통계 분석 기법은 빈도분석이었다. 서울교육대학교 학생들의 자치활동에 대한 의식 및 실태를 분석한 연구 결과, 첫째, 학과 자치활동의 경우, 응답자의 82.9%가 학과 회의나 행사에서의 학생 참여도에 대하여 부정적인 생각을 갖고 있고, 학과 자치활동시 가장 큰 애로사항은 학생들의 관심 부족이라고 생각하는 것으로 나타났다. 또한, 가장 활성화되어야 할 학과 자치활동으로 MT·수학여행·축제 등의 다양한 학과 행사를 꼽고 있었다. 둘째, 총학생회 자치활동의 경우, 총학생회에서 주도하는 집회나 행사에 대한 학생들의 참여도는 매우 낮은 것으로 조사되었으며, 앞으로 활성화되어야 할 총학생회 활동에 대해서는, 축제· 체육대회· 신입생 O.T. 등과 같은 연례적인 대규모의 이벤트성 행사에 많은 관심을 보여 주었다. 일반적으로 학생들은 총학생회의 역할이 주로 학생들의 의견을 대변하는 것으로 인식하고 있었으며, 총학생회와 학교 당국의 관계에 대한 학생들의 인식은 상당히 부정적으로 나타났다. 셋째, 동아리 자치활동의 경우, 상당수의 학생들은 동아리 활동시 적절한 공간이나 예산의 부족 등으로 어려움을 겪는 것으로 나타났다. 응답자들은 대체로(55.1%) 지도교수제의 필요성을 인식하고 있었으나, 동아리 지도교수의 역할 및 참여 정도에 대해서는 다소 아쉬움을 나타내고 있었다. 넷째, 축제 활동의 경우, 상당수의 학생들이 축제 행사에 방관적이거나 소극적으로 참여하는 것으로 조사되었으며, 적극적으로 축제에 참여하는 비율은 25% 정도인 것으로 나타났다. 또한, 공연이나 오락행사 등이 축제 때 보다 활성화되어야 한다고 생각하는 것으로 나타났으며, 축제때 주점 등을 통한 음주 문화를 개선하자는 의견도 있었다. 이상과 같은 연구 결과들을 바탕으로 교육대학교 학생 자치활동의 활성화 방안을 제시하면 다음과 같다. 첫째, 학생 자치활동의 최대 관건인 학생들의 관심을 적극 유도하기 위한 다양한 유인체계를 갖추어야 할 것이다. 둘째, 생산적인 학생 자치활동의 활성화를 위해, 교육대학생의 정체성을 고양하거나 최근 많은 학생들의 관심을 모으고 있는 학생들의 권익 보호와 복지 증진을 도모할 수 있는 독특한 자치활동 프로그램들을 강화해야 할 것이다. 셋째, 학생 자치활동에 대한 교수들의 적극적인 관심과 함께, 학교 당국과 학생 자치기구 간의 관계 개선 노력이 더욱 활발히 전개되어야 할 것이다. The purpose of this study was to investigate students' opinions of their activities in Seoul National University of Education and to suggest some propositions for the development. The data were collected from 321 students, and frequency distribution and percent rate methods have been adopted. The conclusions are as follows: (1) Department students association activities Few students have taken part in the activities. They showed the opinion that membership training, trip for educational purposes, and festival should be strongly activized. (2) General students association activities Fewer students have taken part in the activities. They wanted that athletic meeting and freshman orientation are improved. (3) Circle activities There have been found many difficulties in the activity space and the budget lack. They requested more positive role of the advisor. (4) Performance activities Most students participated passively in the activities. They hoped that more music programs and recreation programs should be developed. In order to develop students' activities, students positive participation, extension of programs, and agreeable relationship between the university authorities and the general student association are needed.

This experiment was conducted to clarify the effect of daminozide on leaf area, shoot growth, and endogenous growth substances in dwarfing rootstocks of apple, M26 and MM106. The results were summarized as follows. When compared to control, leaf area and shoot growth were inhibited by daminozide treatments. The higher the concentration of daminozide, the more severe the inhibition of the leaf expansion and shoot growth in M26, whereas there was no significant difference among treatments in MM106. The emergence of lateral shoots and / or spurs was increased by daminozide treatments compared to control. The secondary growth was significantly promoted by daminozide treatment in M26, but not significantly in MM106. The diameter growth was no statistically different among treatments both in M26 and MM106. The higher the concentration of daminozide, the lower the activity of auxin-like substances up to the 34th day after treatment of daminozide, while higher the activity of inhibitor in both rootstocks. Two months later, the activity of auxin-like substances in 1,500ppm treatment was higher than that of control, but that in the concentration of more than 1,500ppm lower than control in M26 rootstocks. In contrast, the activities of inhibitor were not significantly different among treatments in the M26. In MM106 rootstocks, the activities of both auxin-like substances and inhibitor in daminozide treatments were higher than in control.

This is a study on the housing environment and its problems with special reference to its demand and supply problem in this regional city. The city of Cheong-ju is generally known as an educational, cultural, and also well regarded as a good city to live in comfort. But the housing problem is one of serious problems in this city than in any other cities. It seems that resolving the problem in near future may not be possible but as the government has designated this city as one of core regional cities the housing problem in this city may be dealt with better priority. This paper looked into the houing demand and its supply and then pursued on the housing environment in order to find ways. to improve the situation in this seemingly stabilized city.

최규일,성기용,정태균,이주환,허장현,고광용,이규승 한국환경농학회 2002 한국환경농학회지 Vol.21 No.4

방울토마토의 생산단계에서의 잔류허용기준 설정과 수확후 저장기간중 경시변화 및 세척에 의한 잔류농약의 감소양상을 파악하였다. 해당약제를 안전사용기준의 기준량 및 배량을 각각 시설재배 포장에서 살포후 10일간 잔류양상을 조사하였고, 실온 및 냉장조건 하에서의 저장실험 및 세척에 따른 전류농약의 잔소량을 파악하여 생산단계부터, 출하, 저장, 소비단계까지의 잔류량을 예측할 수 있는 모델개발을 위한 자료로 이용하고자 연구를 수행하였다. Dichlofluanid와 iprodione은 포장조건에서 반감일수가 기준량 2.2, 3.3일 이었으며, 배량은 3.5, 5.4일로 나타났다. 저장조건하에서의 약제별 반감기는 포장조건보다 잔류량의 감소속도가 느린 것으로 나타나 반감일수가 증가하였고, 세척방법에 의한 잔류농약의 감소량을 조사한 결과 세제 사용시의 평균제거율은 dichlofluanid는 73.7%, iprodione은 64.3%로 나타났고, tap-water 사용시에는 dichlofluanid 73.5%, iprodione 63.5%로 나타났다. 이러한 결과는 작물의 생산단계에서 구한 합리적인 희귀식을 이용하여 잔류농약의 경시변화를 파악하고, 저장 및 세척과정을 거쳐 최종 소비단계에서의 잔류농약의 수준을 평가할 수 있었다. We studied the residual patterns of two fungicides, dichlofluanid and iprodione, in cherry tomato greenhouse after applying with the recommended and double dose. Also, the degradation patterns during storage periods of up to ten days were compared between at room temperature (20℃) and at cold temperature (4℃). Removal rates of fungicides by washing with tap-water and detergent solution (0.1%, 0.2%) were measured. Half-lives of dichlofluanid and iprodione in greenhouse cherrytomato were 2.2~3.5 and 3.3~5.4 days, respectively. During the storage period, the residues were dissipated more slow. Removal rates were 62.8~80.3% by tap-water, 60.4~83.1% by 0.1% detergent solution, and 65.3~77.6% by 0.2% detergent solution. So, we can predict of terminal residues from cultivation period to marketing, storage and consuming.

저자들은 호흡곤란, 흉부불쾌감, 심계항진 등을 주소로 내원한 환자에서 경흉부 및 경식도 심초음파 검사상 주폐동맥에서 이완기에 전행하는 지속적인 혈류의 흐름을 관찰하고, 관상동맥 조영술을 통해 좌전하행지 중간부위와 우관상동맥 근위부에서 각각 기시하여 공통경로를 이루면서 주폐동맥으로 유입되는 양측성 관상동정맥루를 보이는 드문 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. A coronary arteriovenous fistula is infrequently encountered vascular communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common congenital anomaly that can affect coronary perfusion. Bilateral involvement of coronary fistula constitutes an uncommon subgroup of coronary arteriovenous fistulas. A 69 year-old female patient presented with chest discomfort, palpitation, and dyspnea. In the echocardiography, doppler color flow imaging visualized abnormal flow signals with mosaic appearance in the main pulmonary artery during diastolic phase. Coronary angiography revealed arteriovenous fistula arising from the left anterior descending artery and the right coronary artery. Both coronary arteriovenous fistulas drained into the main pulmonary artery. We report a case of bilateral coronary arteriovenous fistula that was confirmed by echocariography and coronary angiography.
