A new sesame variety Kangbaek was developed from Yeongnam Agricultural Research Institute in 2004. Cros wasmade by lodging resistant SP9003-3 line to the F1with high yielding capacity, folowed by pedigree selection, yield test and RYT by the sesame breeding team at the National Insti-tute of Crop Science up to 2003. The variety showed higher disease resistance, especially phytophothra disease, and lodging resis-respectively. It's 1000 grains weight was about 2.54 g indicating 0.03 g heavier than that of Yangbaekkae, and it's oil content wasabout 52%. Kangbaek also contained total 7.65mg/g of such lignans as sesamin and sesamolin. The average yield of Kang-baek was 82 kg per 10a at the national-wide regional performance.

Investigation of the April 2000 forest fire damage in Kang-won Province, Korea, using RADARSAT data

Kang, Sung Chul,Seo, Jin Won,Lee, Tae Hee,Park, Sang Eun,Hong, Suk Young,Moon, Wooil M. 대한원격탐사학회 2000 International Symposium on Remote Sensing Vol.16 No.1

The series of forest Fires in Kangwon Province in April, 2000, were one of the mast serious ones in the Kang-won Province in recent years. The fire damaged areas are extensive and this paper investigates the utility of the satellite image data, particularly the RADARSAT SAR data. One of the main objectives of this study included evaluation of potential usefulness of the C-band RADARSAT data in the detection of forest fires in mountainous areas. Among several fire damaged sites, the area near Samchuk (city) was selected as the main study area and mufti-temporal RADARSAT(raw) data were acquired and the processed results were comparatively investigated with the IRS-1c data acquired shortly after the fire. To identify the burnt area from the undamaged background in the optical imagery, supervised classification and NDVI processing were carried out and tested with the IRS-1C data. For this experiment, several sets of raw RADARSAT standard and Fine mode (S4, F3, ascending orbit) data were processed and the final image was formed. In addition to the final image, sigma nought (σ°) was catnputed and compared for the burnt area against the undamaged areas. Because of the steep slopes in the study area and subsequent deviation from the flat surface scattering models, the fire scars in the sigma nought (σ°) image were not apparent. However, fire scars are slightly detected in the difference and ratio images obtained from the signal intensity data acquired at different dates (bath before and after fire). Texture analysis of the image data including the burnt areas were carried out using the Multiplicative Markov Random-Field (MMRF) algorithm. The detection of the fire damaged area from both standard mode and fine mode RADARSAT was not as straightforward as in optical data. However, Previous studies with ERS-1 S_AR and RADARSAT data in Indonesia and in the North American Plains indicate that C-band SAR data provide us with an effective tool for studying the forest fire damages. However, the application of C-band SAR data to the analysis of the forest fire areas requires careful processing of the data with realistic scattering models.

Background: Pityriasis versicolor(PV) is a superficial mycosis, theoretically unusual in children. Epidemiologic and clinical data for children with PV under 14 years were collected. Objective . The purpose of this study was to evaluate the clinical features of PV in the young. Method: We included all cases of PV in patients under 14 years of age observed in our department from 1981 to 1995. All cases were diagnosed on the basis of clinical criteria and were confirmed by microscopic examination. Results : From 1981 to 1995 we encountered 32 cases of PV in children, compared with 637 cases in adults; thus children represented 4.7% of all cases. The ratio of male to female was l. 7:1. Among the age groups, the incidence was the highest in the 10-14 years(43%). The monthly prevalence was the highest in August. Distribution of the lesions were the face(40.9%), neck (25%), chest(13.6%), back(11.3%), extremities(6.8%) and abdomen(2.2%). The incidence of hypopigmented lesions was 70.4% and that of hyperpigmented lesions was 29.6%. Conclusion : This study confirms that the face is a predilectionl site for PV in children and all facial lesions are hypopigmented. Other clinical features are variable and similar to those of adults. (Kor J .Dermatol 1997;35(3): 431-434)

백영숙(Young Suk Paik),강병재(Byeong Jae Kang) 한국열린유아교육학회 2014 열린유아교육연구 Vol.19 No.2

본 연구는 어린이집 교사의 정서노동과 교사-유아 상호작용과의 관계에서 교수효능감과 교수창의성의 매개효과를 알아보기 위하여 수행하였으며, 서울과 경기 및 광주와 전남북 지역에서 어린이집 교사 299명을 대상으로 연구를 수행하였다. 본 연구의 결과, 첫째, 어린이집 교사의 정서노동과 교수효능감, 교수창의성 및 교사-유아 상호작용 간에는 정적인 상관이 있는 것으로 확인되었으며, 둘째, 어린이집 교사의 교수효능감과 교수창의성은 어린이집 교사의 정서노동이 교사-유아 상호작용에 미치는 영향력을 정적으로 매개하는 것으로 확인되었다. 어린이집 교사의 정서노동은 교사-유아 상호작용을 설명하는 중요한 변인이지만, 어린이집 교사의 교수효능감과 교수창의성과 결합되었을 때 교사-유아 상호작용을 더욱 잘 설명하는 것으로 판단할 수 있다. 따라서 어린이집 교사의 교수효능감과 교수창의성은 교사-유아 상호작용을 설명하는 중요한 변인이라고 할 수 있다. The purpose of this study is to examine the relations between emotional labor and teacher - young children interactions in the mediating effects of teaching efficacy and the instructional creativity of day care center teachers. The subjects are 229 day care center teachers working in Seoul, Kyung-ki province and Gwangju province, Jeolla north and south province. Analysis of data is conducted with SPSS 18.0. The results are as follows. First, there were significantly positive relationships among emotional labor, teaching efficacy and instructional creativity, and teacher-young child interactions of day care center teachers. Second, emotional labor showed significantly positive effects on teacher-young children interactions in the mediating effects of instructional creativity and the teaching efficacy of day care center teachers. Therefore, important variables in explaining teacher-young children interactions are instructional creativity and the teaching efficacy of day care center teachers.

스마트 기기 사용 시간에 따른 유아의 행동 특성 분석

강병재(Kang Byeong-Jae),백영숙(Paik Young-Suk) 학습자중심교과교육학회 2019 학습자중심교과교육연구 Vol.19 No.21

본 연구는 스마트 기기 과다 사용이 유아의 일상생활 전반에 미치는 부정적인 영향을 구체적으로 확인하기 위하여 수행하는 것으로서, 이러한 연구의 의도를 달성하기 위하여 스마트 기기 사용 시간을 3개 집단으로 구분하여 총 621명의 만5세 유아 를 대상으로 연구를 수행하였다. 연구 수행결과, 유아가 스마트 기기 사용 시간이 많을수록 연구에서 설정한 일상생활영역, 교육기관영역, 또래관계영역 그리고 병리현상영역에서 부정적인 행동을 하는 유아가 많은 것으로 확인되었다. 구체적으로는 스 마트 기기 사용 시간이 일 평균 10분미만인 1집단에서 부정적인 행동을 하는 유아의 비율보다 스마트 기기 사용 시간이 일일 평균 45분 전후인 2집단에서 부정적인 행동을 하는 유아의 비율이 높았으며, 이보다는 일일평균 스마트 기기 사용 시간이 85분이상인 3집단에서 부정적인 행동을 하는 유아의 비율이 더 높았다. 따라서 만5세를 대상으로 분석한 결과에 의하면, 스마트 기기 사용 시간이 많을수록 부정적인 행동을 하는 유아의 비율이 높아지는 것으로 예측할 수 있다. 그러므로 유아의 스마트 기기 사용에 대한 가정과 유아교육기관에서의 관심과 기준이 필요하며 나아가서는 스마트 기기 사용이 유아의 긍정적인 발달에 영향을 미칠 수 있도록 지도와 감독이 이루어져야할 것이다. This study was conducted to specifically identify the negative effects of overuse of smart devices on the overall daily life of young children. The study was conducted on five-year-old children. As a result of the study, the more time the smart device is used, the more young children have problem behaviors in daily life, educational institution, peer relationship and pathology. Specifically, the proportion of young children who have negative behaviors in the group 2 with the smart device usage time around 45 minutes per day is higher than the proportion of young children who have negative behavior in the group 1 having less than 10 minutes of daily smart device use. In addition, the percentage of young children who had negative behaviors was higher in the group 3 with more than 85 minutes of daily average smart device use time than the group 2. Therefore, according to the analysis results of the five-year-old, the more time to use the smart device can be expected to increase the proportion of children who have a negative behavior. In addition, the usage time of the smart device can be predicted to influence the negative behavior of the young children. Therefore, attention and standards are needed at home and early childhood education institutions for the use of smart devices by children, and further guidance and supervision should be made so that the use of smart devices can affect the positive development of children.

Pathological study on rabbit haemorrhagic disease in young rabbits

Kim, Young-suk,Lee, Yong-soon,Seo, Kang-moon,Lee, Yeon-hee,Park, Jae-hak The Korean Society of Veterinary Science 1999 大韓獸醫學會誌 Vol.39 No.2

We investigated the pathological changes in young rabbits which were experimentally infected with rabbit hemorrhagic disease virus (RHDV). Experimental infection of RHDV was carried out in both thymectomized and non-thymectomized young immature rabbits and adult rabbits. None of young rabbits infected with RHDV died during the experiment. Histologically, single or focal hepatocellular degeneration and necrosis with mild lymphocyte infiltration were observed in the rabbits killed at 30 hours and 5 days PI. Lymphocyte infiltration was more severe at 5 days PI than at 30 hours PI. RHDV antigens were mainly detected in the degenerating hepatocytes adjacent to the infiltrated lymphocytes at 30 hours PI and 5 days PI. In electron microscopical observation, infiltrated lymphocytes in the lesions had large nuclei without cytoplasmic granules and interdigitated with adjacent hepatocytes. It is assumed that infiltrated lymphocytes in hepatic lesions in RHDV infected young rabbits are T-lymphocytes and originate from peripheral lymphoid organs or tissues rather than from thymus.
