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.

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.

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.

이윤미,박재옥,이연희 服飾文化學會 2004 服飾文化硏究 Vol.12 No.2

The purpose of this study is to investigate design process and production in the Korean knitwear industry and to examine the possibility fur our knitwear industry to develop into the developed countries' model. This purpose was empirically pursued through questionnaires, of which respondents were 110 designers, merchandiser(MD), and top managers of knitwear companies and jobbers in Seoul. The questionnaires were analyzed on the basis of such statistical tools as χ^(2)-test, t-test, and one-way ANOVA. Findings of this study were as follows. Designers of knitwear companies evaluated that their design is more creative than that of designers of jobbers. But designers of knitwear companies and jobbers all responded that they obtained their design ideas from samples produced by leading foreign knitwear companies. The dominant form by which knitwear companies use jobbers was that knitwear companies do a major part of designing and order jobbers to elaborate it and produce knitwear samples. The most important reason of hiring jobbers was to obtain specialized technical skills and knowledge.

김윤숙,김중만,백승화,문정옥,황호선,김인숙 圓光大學校 1987 論文集 Vol.21 No.2

배추를 다듬기 하는데 발생한 폐기량은 7.5∼14% (w/w)이었고 10±2℃에서 30일간 방치한 경우 약 17∼25% 발생하였다. 간절임 배추의 pH값은 저장온도가 낮을수록, 염도가 높을수록 높았으나 calcium chloride 첨가가 절임배추의 pH값의 변화에는 영향을 주지 않았다. 유리당의 함량변화는 최소 약 4% 수준에서 산의 함량과는 반비례적으로 변화하여 저장 90일에는 소금농도가 낮고 저장온도가 높은 경우 적게 감소되었다. 균수변화에서 세균과 효모는 전 기간을 통해 증가한 반면, 곰팡이는 감소하였다. 한편 산의 첨가와 CaCl? 첨가시 소금으로만 절인 경우보다 세균과 효모는 낮은 속도로 증가했다. 저장중 경도는 온도가 낮고 염도가 높으며 젖산을 첨가한 경우 다소 높게 유지됐고, CaCl? 첨가의 경우 잎과 줄기에서 월등히 높았다. 휘발산과 불휘발산의 함량변화에서 온도가 낮고 염도가 높은경우 불휘발산의 함량이 낮았는데 특히 젖산 첨가시 불휘발산의 증가를 억제하는 것으로 나타났다. flavor score 는 저온과 고염도 젖산첨가시 유리하였다. This study was to investigate the effects of storage temperature, lactic acid and calcium chloride addition about the pH values, sugar content, firmness, volatile and nonvolatile acidity, microbial counts and flavor of the salted chinese cabbages during storage (90 days), and trim loss of chinese cabbages during the trimming of raw and storaged (30 days) chinese cabbages. The waste rate was in the course of trimming of raw chinese, cabbages was 7.5-14(w/w). The proportion of trim loss was highly correlated to sunshine duration, temperature, humidity and handling for the storage. Free sugar was decreased fast and much in the case of high temperature and low level sodium chloride in comp rison of low temperature and high sodium chloride, but ?? and lactic acid did not affect its changes. Time to reach the lowest pH values were fast in the case of high temperature and low salt content. Lactic acid affected inital pH value (4.38-4.57) and constant pH value in each case was increased at low salt content, at high temperature, and then the pH values were slowly increased when volatile acidity was increased. Firmness was high in the case of addition of lactic acid and calcium chloride, low temperature, high sodium chloride concentration. Especially, calcium chloride addition remarkably showed high firmness. Flavor score was high in the case of low storage temperature, high yeast counts were slowly increased in spite of low temperature and high salt content, but mold counts were slightly increased during all period Lactic acid, low temperature and high sodium chloride were effective to inhibit the growth of microorganisms. Volatile and nonvolatile acidity was increased during all storage period ; however, lactic acid and low temperature storage inhibited their increase. To conclude, quality of salted chinese cabbages was effective at low temperature storage, lactic acid and calcium chloride addition, and high salt concentration.
