윤옥병 대한악안면성형재건외과학회 2002 Maxillofacial Plastic Reconstructive Surgery Vol.24 No.3

Most of Oral & Maxillofacial surgeon used to take free skin graft on the large postoperative mucosal wound which could not be dissolved with primary closure. However, there were many difficulties such as the presence of new scar formation on the donor site, discomforts caused by to the presence of hair and fetid odor intraorally, and especially difficulty of choice of the donor site in the case of young patients. Therefore author tried to primary closure by use of collagen menbrane on the mucosal defects caused by the palatal pathologic lesion, mucosal dehiscence followed by the bone graft on the alveolar cleft, and vestibuloplasty on the area of vestibular flattening caused by trauma. Author could induce good healing processes and results without additional scar formations and further discomforts.

외환위기 전후 금리·환율·주가 변동성에 관한 분석 : 금융시장간 변동성 전이를 중심으로

윤옥자,강규호 한국은행 2004 經濟分析 Vol.10 No.1

As regulations in financial markets have been substantially alleviated through financial liberalization and market opening following the currency crisis, asset prices such as interest rates, the exchange rate and stock prices may reflect diverse information more efficiently. But at the same time, the increased volatility of asset prices may give rise to financial unrest. Based on a multivariate GARCH model, this paper studies volatility dynamics in bond, foreign exchange and stock markets and examines whether there exist volatility spillovers across the three markets in pre-crisis and post-crisis periods. The results show that there are volatility spikes where volatility increases in the short term and promptly returns to the average level in all three markets. Average volatility levels are substantially higher after crisis than in the pre-crisis period. From the aspect of volatility spillover, a shock occurring in a particular market is found to be transmitted to other markets instantly in the post-crisis period when market linkages had been augmented due to financial liberalization and capital market opening. The stock market, especially, is found to play a leading role in inter-market volatility spillovers. This is attributable to the fact that most of the foreign capital for portfolio investment since the crisis has flowed into the stock market. 외환위기를 거치면서 금융 자유화개방화의 진전으로 각종 규제와 제한이 크게 완화됨에 따라 금리, 환율, 주가 등 금융자산가격은 다양한 정보를 보다 효율적으로 반영하게 되었다. 그러나 이 과정에서 가격변동위험이 증대됨에 따라 금융불안이 심화될 가능성은 더욱 커지게 되었다. 본 연구에서는 다변량 GARCH모형을 이용하여 외환위기 전후 채권외환주식시장의 변동성 행태변화와 각 시장간 변동성전이(volatility spillover)관계를 분석한 후 정책적 시사점을 찾아보았다. 분석 결과 금리환율주가변화율에 있어서 변동성이 단기적으로 크게 확대되었다가 평균수준으로 복귀하는 변동성 급변(volatility spike)현상이 빈번하게 발생하였을 뿐 아니라 외환위기 이후 변동성의 크기가 대체로 확대된 것으로 나타났다. 변동성 전이의 측면에서는 외환위기 이후 금융시장의 자유화개방화 등으로 금융시장간 연계성이 한층 강화되면서 어느 한 시장의 충격이 다른 시장에 보다 신속하고 밀접하게 영향을 미치는 것으로 나타났다. 특히 주식시장이 금융시장간 변동성 전이의 주도적 시장으로 등장한 것으로 밝혀졌는데 이는 외환위기 이후 대규모 외국인 포트폴리오투자자금이 주식시장으로 유입되었기 때문으로 보인다. 따라서 통화당국은 장기금리 안정화를 위해 채권시장뿐 아니라 주식 및 외환 시장에 대한 모니터링을 강화해야 할 것이며, 금융자산가격이 보다 안정적으로 형성되고 외부충격이 효과적으로 흡수될 수 있도록 지속적인 시장선진화와 구조조정 노력을 해 나가야 할 것이다.

윤기옥 인천교육대학교 초등교육연구소 2001 교육논총 Vol.18 No.-

교육의 질, 수업의 질의 향상은 모든 사람들의 관심사가 되어 왔고, 이와 함께 장학, 특히 수업장학도 시대?사회의 변화에 따라 발전하여 왔다. 수업장학은 다양한 수준에서 다양한 형태로 이루어질 수 있으나, 최근에 급속히 이루어지고 있는 시대?사회적인 변화 속에서 학교중심 경영과 함께 강조되는 것이 교내장학이다. 교내장학은 사회에 따라 다양한 문제점을 나타내는 가운데 변화하고 있다. 본 연구에서는 일반적으로 나타내고 있는 교내장학의 변화 동향, 문제점, 앞으로의 장학연구의 방향을 살펴보며, 장학의 발전방향을 교육의 도덕적?윤리적 기초인 민주주의와 관련하여 탐색해 본다. Trends and Development Directions of School Supervision Kiok Yoon. Based on the concern for quality education and quality learning, supervision, specifically speaking, instructional supervision has been developing, reflecring the characteristics of the times and society. Recently due to the rapid change of the society, the school-based management and school supervision has been emphasized. Even though supervision develops unfolding the problems the society faces, general trends and development directions can be elicited. The general trends of supervision are (1) shift form individual to group focus, (2) shift from preoccupation with inspection and evaluation toward a function of facilitating growth, (3) shift from a micro to a macroconceptualization of supervisory context, (4) emphasis on creating community, both within the school and with the larger community which the school serves. The issues in supervision are (1) simplistic solution to dilemmas, (2) reintegration with curriculum, (3) recognition as a profession, (4) methodological rigor, (5) moral foundation. Traditional persistent questions such as the effect of supervision on student achievement, the factors related to supervisory efficacy, comparison of supervision models, and innovative research questions such as the use of new inquiry methods, historical examination of issues if diversity the effect of the knowledge, skills and attitudes of the supervisee on supervision, the effect of the managerial/organizational theories from the field of business on supervision and so forth should be explored using not only qualitative method but also qualitative method. But most of all a moral and ethical center as a foundation for assessing roles, responsibilities, programs, and achievements of school supervision is urgently needed. Without moral foundation of education, little guidance exists for determining what supervisors and supervision programs should be doing or accomplishing. And democracy as educative hope can be the moral foundation for supervision. The field of supervision must dedicate itself to the incessant struggle of making schools the center of democratic inquiry.

濟州道 一部地域의 絲狀蟲症患者와 象皮病患者에 對한 學的調査 및 Spatonin에 依한 集團化學療法의 臨床報告

文玉綸 서울大學校 保健大學院 1968 公衆保健雜誌 Vol.5 No.2

Filariasis survey was carried out on 1107 subjects of 3 villages located in southern county of Che Ju Do from June to October of 1968. Mass chemotherapy with spatonin (Diethylcarbamazine) on 208 microfilaria positive cases was followed after the survey. The summarized results are as follows: 1. Epidemiological characteristics of microfilaria positives and elephantiasis patients. Microfilaria rates varied by areas with average of 20.9% ranging from 17.3% to 27.1%. Distribution of microfilaria rate by sex did not show any significant difference, however, the distribution of microfilaria rate by age showed two peaks, one for 21-30 years and the other for 41-50 age group. For the remarkable dropped rate for 31-40 years age group, more studies may be necessary to give explanations. The range of microfilaria counts per 40㎣ of blood (density) varied widely from 1 to 788, although the most of microfilaria positives (40%) had less than 25 Mf (microfilaria) per unit of blood. Also the microfilaria density showed interesting correlation between Mf. rate and the density by villages; where the rate was high, the density was proportionately high. The survey by family unit revealed that 40% (average) of total households surveyed had Mf positives, and 80% of positive households had one or two positive family members. On the survey of clinical filariasis, 41 of 1107 subjects were found to have elephantiasis. Female showed predominantly higher rate (2.2 times) compared with that of male. The distribution by age showed definite tendency of increasing rate by increasing age; in more than 80% of the cases, the elephantiasis appeared after 20 years of age, even though the earlest case was 14 years old girl. Sites for elephantiasis were found in 75% on lower extremities, 5% on upper extremities and 20% on both extremities. Erythematous swellings of extremities accompanied by fever seemed to occur once or twice annually. Some contributing factors for the episodes seemed to be related to over exhaustion and/or injuries. 2. Mass treatment with spatonin, its efficacy and side reactions. Mass chemotherapy with spatonin on 208 microfilaria positives gave all excellent efficacy according to the results of blood smear immediately after the last dose of the drug; four experimental groups (by village) treated with 6mg of spatonin/kg body weight every day, every other day for 6 doses, same amount of the drug 6mg/kg of b.w. every other day for first 2 doses and every day for rest of doses, and 3mg/kg of b.w. every other day for 14 doses, showed similar results (92.6%, 91.2% and 88.4% of rate turning to microfilaria negative) for 6mg/kg of b.w. groups regardless of way of administration except 3mg/kg of B.W. group, which had much inferior efficacy than the another groups(only one of five became negative). Six doses of 6mg/kg b.w. spatonin may be enough to turn the positives to negative, although long term follow up study is strongly desired. The side reactions due to the drug was relatively severe especially after the first and second doses. More frequent symptoms were anorexia, fever, headache, joint pain, and dizziness, which became milder when the drug was administered every other day. From this study, it was tentatively concluded that filariasis is one of important endemic diseases in the area studied. and spatonin could be a potent drug for control of filariasis when administered properly.

황윤정,황승만,최진수,김무식,백성옥 嶺南大學校 環境問題硏究所 1998 環境硏究 Vol.17 No.2

요약문 본 연구는 각종 먼지 가운데서도 독성이 가장 큰 것으로 알려진 도로먼지에 함유된 미량원소 성분이 조성 및 특성을 파악하기 위해 1992년 1월에서 10월가지 주거지역, 상업지역, 공업지역, 교외지역, 전원지역 등에 위치한 도로에서 시료를 채취하였으며 채취된 시료는 산으로 추출한후 ICP로 분석하였다 . 그 결과 토사 및 황사현상과 같은 자연발생원과 연관지을 수 있는 Al, Ca, Mg, Ti, Si, Na, K의 농도가 지역에 따라서는 전원지역과 교외지역에서, 그리고 도로포장 형태에 따라서는 비포장 도로에서 높게 나타난 반면에, 각종 연소 및 차량과 같은 인위적인 발생원과 관련이 있는 As, Cr, Mn, Zn, Pb, Cu, Ni는 공업지역 및 상업지역, 그리고 아스팔트에서 비교적 높게 검출되어 이러한 미량원소성문들의 농도분포는 지역에 따라, 그리고 도로포장 형태에 따라 특징적인 양상을 나타내는 것으로 조사되었다. 또한 As, Pb, Al 등의 일부 미량원소성분들의 농도는 계절에 따른 차이를 나타내었으며, 농축계수에 의한 평가결과 농축계수가 낮게 나타난 Na, Si, Ti, K, Al 등은 자연발생원에 의해 상당한 영향을 받는 반면에 As, Pb, Zn 등은 농축계수가 매우 높게 나타나 이들 성분의 경우에는 인위적인 발생원에 의한 기여도가 큰 것으로 평가되었다. Abstract This study was carried out to characterize the trace elements in street dust known to contain several toxic elements. Street dust was collected in residential, commercial, industrial, suburban and rural area of Taegu and on the vicinity of Taegu from January to October, 1992. Total amount of 16 trace elements in street dust were analyzed by ICP spectrophotometer. While the levels of As, Cr, Mn, Zn, Pb, Cu and Ni were higher in industral and commercial area than any other area by sites and the highest levels appeared on asphalt and cement street by street conditions. Also the concentrations of some trace elements originated mainly from soil (e.g. Al, Ca, Mg, Si, Na) were higher in rural and suburban area by sites and the highest levels appeared in unpaved street by street conditions. The concentrations of several trace elements such as Aa, Pb, Al appeared seasonal differences. The estimated enrichment factors (EF) for Na, Si, Ti, K and Al components showed with soil compositions appeared to have low values, while As, Pb and Zn components showed relatively higher values. These results imply that the latter constituents were likely to be affected by dry and wet depositions of atmospheric particles orginated from anthropogenic sources such as fuel combustion and refuge burning.
