본 연구에서는 교사-유아 간 애착안정성 정도에 따라 유아의 스트레스 정도 및 유아의 스트레스 대처행동에 어떠한 차이가 있는지 알아보고자 하였다. 연구 문제에 따른 연구 결과는 다음과 같다. 첫째, 교사-유아 간 애착안정성 정도에 따른 유아의 스트레스 정도에는 통계상 유의미한 차이가 없었고, 유아 스트레스 하위 영역인 교사, 또래, 학습 환경에서도 통계상 유의한 차이가 없는 것으로 나타났다. 다만 학습 활동영역에서 교사-유아 애착안정성이 낮은 유아 집단이 높은 집단보다 스트레스를 더 많이 받는 것으로 나타났다. 이러한 결과는 교사-유아 애착안정성 정도에 따라 교사, 또래,학습 환경 요인과 관련된 유아 스트레스에 차이가 없으며, 교사-유아 애착안정성이 높을수록 유아가 학습활동 요인과 관련된 스트레스를 덜 받는다는 것을 알 수 있다. 둘째, 교사-유아 간 애착안정성 정도에 따른 유아의 능동적, 수동적, 신비적 스트레스 대처행동 양식에서 통계상 유의한 차이가 나타났다. 교사-유아 간 애착안정성 정도가 높은 집단이 능동적 대처를 더 많이 하고, 교사-유아 간 애착안정성 정도가 낮은 집단이 수동적 대처와 신비적 대처를 비교적 더 많이 한다는 것을 알 수 있다. Due to lack of systemic program regarding physical activity in children, the study is to identify the constitution and development of the Natural Physical Activity Program by offering environmentally friendly elements such as wind, sun, mountain, sea, river, tree, flower, field for children. We expect children to learn the relation with nature, respect for life, understanding and love, importance of working together, and etc. The research questions for the purpose of this study are as followed: First, this study is going to identify the overall awareness and its needs of the Natural Physical Activity Program among preschool teachers. Second, we will look over how we can develop such program for preschool teachers. And a direction proposal on Natural Physical Activity Program. About 250 preschool teachers resided in Busan and Gyug-nam province were urged to participate in a research questioning their awareness and needs of the program. Among 250 preschool teachers, we choose 20 of them to interview about the goal, plan and development direction of the program. The result of the study is following as: First, most of the preschool teachers have a positive view on the Natural Physical Activity Program, and they agree that the program is highly needed to use. However, it is urge that overall education environment need to be improved to achieve its goal of the program. Second, the interview on the development direction is categorized as need, development direction, teaching method, evaluation method, activity, problem, improvement, solution, and etc. and, Third, the contents of the program include environmentally friendly elements such as wind, sun, mountain, river, sand, tree, flower, field to induce children’s interest and whole-person education. The contents of the program are expected to deliver hands-on experience for children. And also, the program includes physical activity using a nature object. Based on the potential problems we identified, a next study is expected to deal with following points. First, more empirical research is needed to prove the effectiveness of the program in a broad way by proposing a program that can be applicable at child-education center. Second, the study developed contents to make children feel enjoyable about nature. Unfortunately, in-depth research and development of such program is not sufficient. In this respect, more continuous research on Natural Physical Activity Program is required and need to be widely established.

韓國在來山羊의 體重에 따른 屠體 및 精肉生産量

全海烈,金善丘,趙炳旭,愼澤淳 密陽産業大學校 農業技術開發硏究所 1998 農業技術開發硏究所報 Vol.2 No.1

한국 재래산양 34두로부터 체중에 따른 도체 및 부산물 생산량과 정육율을 조사하였다. 생체중이 13.3kg에서 33.4kg까지 증가함에 따라 도체율은 35.32%에서 45.94%까지 상승하였다. 생체중(X)과 도체율(Y)의 관계는 Y=-4.537 +4.049X-0.067X2으로 추정되었으며 생체중 28KG에서 도체율(48.7%)이 가장 높았다. 도체중이 4.70KG에서 15.34KG으로 증가에 따라 정육율도 64.05%에서 74.31%로 증가하였다. 도체중(x)과 정육율(y)의 관계는 Y= 50.162+3.533X-0.127X2으로 추정되었으며 도체중 13.9KG (생체중30KG)에서 정육율(74.7%)이 가장 높았다. 따라서 재래산양의 적정 도살 시기는 생체중 30KG 내외가 적당할 것으로 사료된다. Thirty-four heads of Korean native goats were used to investigate the yields of carcass and by-products and lean-meat percentage as influenced by live weight. The dressing percentages were increased 35.32% to 45.94% with increasing live weight from 13.3kg to 33.4kg. The regression equation of dressing percentare(Y) on live weight(X) was Y= -4.537 + 4.049X - 0.076X2 and the highest dressing percentage(48.7%) was found at 28kg of live weight. The lean-meat percentages were increased 64.05% to 74.31% with increasing carcass weight from 4.70kg to 15.34kg, The regression equation of lean-meat percentare(Y) on carcass weight(X) was Y =50.162+3.533X-0.127X2 and the highest lean-meat percentage(74.7%) was found at 13.9kg of carcass weight (30kg of live weight). Therefore, it is considered that the optimum slaughter weight of Korean native goat is around 30kg of live body.

Since many people in Korea know more than one language, bilingual aphasia is an important line of research in clinical and theoretical neurolinguistics. Nowadays we meet many people who speak other languages along with Korean, who are immigrants from foreign countries, especially from China. Differential recovery of language affected by an aphasic deficit is documented. In the present work, we introduced a patient with bilingual aphasia who showed different recovery patterns in Korean and Chinese. A 66-year-old man was presented with language disturbance and right hemiplegia. On past medical history, he had received a hematoma evacuation through burr-hole due to left basal ganglia hemorrhage. After the event, he showed nearly global aphasia in Korean, but he showed minimally preserved language function on comprehension and fluency in Chinese. This result suggests that aphasia in bilingual subject may show different pat-terns of recovery between two languages.

황해선,이우교,김영욱 동의대학교 기초과학연구소 1995 基礎科學硏究論文集 Vol.5 No.1

CaS:Ce and Ca_1-χSr_χS:Ce phosphors have been prepared using the sulfurizing flux method and the result of measuring photoluminescence is presented two peaks with extensively strong intensity, when flux (Na₂CO₃) is mixed 30 mol% and activator doped 0.1 mol% in the host (CaS). The two peaks of CaS:Ce phosphor are appeared at 513㎚ and 576㎚ wavelengthes when liminescenct transition in Ce^3+ is given as 5d(²D)→4f(²f_5/2) and 5d(²D)→4f(²f_7/2) and that of Ca_1-χSr_χS:Ce phosphor are shifted toward short wavelength as much as 30㎚ when χ is changed from 0 to 1, but the shape of wavelength is not varied.

Polyacrylonitrile中의 Model Disperse Dye의 擴散

최해구,朴秀敏 新羅大學校 1985 論文集 Vol.18 No.-

Diffusion coefficient of model disperse dye, p-Nitroaniline (p-NA) in polyacrylonitrile (PAN) have been measured in the wide range from 75°to 125℃ by means of sublimation diffusion of vacuum heating system. The plot of Log D vs. 1/T gave a sharp changed-point at 85℃ and this point was considered to be the glass transition temperature, Tg. In the region higer than Tg, these results have given good incidence to the equation, WLF with standard temperature as Tg.

고주파 유도로 라이닝용 마그네시아계 내화 재료 개발

권해욱,이해성 영남대학교 공업기술연구소 2000 工業技術硏究所論文集 Vol.28 No.1

The abilities and fading behaviors of 5 different inoculants were evaluated by the thermal analyses of the melts which were held at constant temperature after addition in induction furnace. The silicon content was preserved at the high holding temperature of 1450∼1500℃, which reduced by oxidation at the low one. The inoculation temperature should be higher to obtain better and reproducible result. The inoculation performance of Ba-Si was the best on the bases of effect and fading behavior

We have encountered a rare case of symmetrical peripheral gangrene complicating Escherichia coli sepsis in a 47-years-old male. He was successfully treated with antibiotics, anticoagulants, and vasodilator. To our knowledge, this is the first report on symmetrical peripheral gangrene complicating E. coli sepsis in Korea.

한국산 무릇(Scilla scilloides complex)의 세포유전학적 연구 : Ⅱ. 제주도 집단에서 게놈의 분포 Ⅱ. Distribution of Genomes in Chejudo Populations

方在旭,崔慧雲 충남대학교부설 생명공학연구소 1992 생물공학연구지 Vol.2 No.-

Cytogenetic analyses were done in thirteen natural populations of Scilla scilloides complex collected from Chejudo. Six genotypes, BB (2n=18), ABB (2n=26), AABB (2n=34), ABBB (2n=35), AABBB (2n=43) and AAABBB (2n=51) were observed, where A and B denote genomes with χ=8 and χ=9, respectively. Genotypes BB, ABB and AAABBB were found for the first time in Chejudo populations. Genotypes BB and ABB were never reported from the Korean populations. Six of the populations investigated were mixed populations of two or three cytogenetic types, and others were pure populations consisting of BB (1), AABB (4) and AABBB (2). AABB genotypes were predominant over other genotypes and AABBB was the next. AA genotypes growing in the mainland of Korea was not found. It was suggested that the Chejudo populations of S. scilloides complex were closely related to the Japanese populations than mainland populations of Korea. The number of B-chromosome ranged from one to four. The B-chromosomes were all isochromosomes (F) and no chromosome fragment (f) was found. The frequencies of B-chromosome were 75% in BB and AABBB genotypes, respectively. The frequency of B-chromosome in AABB plants was similar to that of AABB plants reported in the mainland populations.
