This study was performed to confirm the actual temperature rise on the surface of Buchanan plugger by evaluating the temperature rise on the surface of it, the peak temperature of pluggers of various size using thermocouple. The heat carrier system 'System B Heatsource' (Model 1005, Analytic Technologies, USA) and the Buchanan pluggers of F, FM, M and ML sizes are used for this study. The temperature was set to 200 which Dr. Buchanan's "Continuous wave of condensation" technique recommended on digital display and the power level on it was set to 10. The touch mode was used. Five thermocouples were placed in direct contact with the surface of each size of Buchanan's pluggers at 1 ㎜ increments from the tip to the 4 ㎜ length of shank. Each thermocouple was secured with cyanoacrylate adhesive and orthodontic resin block. The two wire leads of each thermocouple were connected to the appropriate channels of Data Logger. This was configured to simultaneously record input from the five thermocouples. The heat control spring was touched for 1, 2, 3, 4 and 5 seconds, and the temperature rise on the surface of the pluggers were measured at 1 sec intervals for more than 5 seconds with an accuracy of 0.01. Ten trials was determined for each plugger. The average of temperature rise and standard deviation was calculated for each size of plugger. The data were statistically analyzed by one-way ANOVA to determine their significance. The results as follows. 1. The position at which the temperature peaked was approximately at 1∼2㎜ far from the tip of Buchanan plugger (p<0.01). 2. The peak temperature was 215.25±2.28℃ in F plugger, 185.94±2.19℃ in FM plugger, 169.51±9.12℃ in M plugger, and 160.79±1.27℃ in ML plugger and the peak temperature was highest in F type and followed by, in descending order, FM type, M type. ML type showed the lowest peak temperature (p<0.01). This results suggest that the actual temperature on the surface of the pluggers does not correlate well with the temperature set on digital display. Heat concentrates around the tip. The larger plugger reveals lower temperature rise relatively.

Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)­test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

조난주,이상호,이난영 大韓小兒齒科學會 2007 大韓小兒齒科學會誌 Vol.34 No.4

본 연구의 목적은 법랑질 시편에 수종의 불소 제재를 도포한 후 우식 예방 효과를 광밀도 및 미세경도 측정을 통해 평가하는 것이다. 소의 절치를 이용하여 80개의 법랑질 시편을 제작하고 각 군당 20개씩, 네 군으로 나누었다. I군은 대조군으로서 아무런 처치도 하지 않았고 II군은 acidulated phosphate fluoride(APF) ge1(60 seconds taste^(??), PASCAL, USA)을 4분간 적용한 후 수세하였다. III군은 Fluor Protector^(??) (Ivoclar Vivadent, Liechtenstein)를 IV군은 CavityShied™(Omnii Pharmaceuticals, USA)를 1분간 도포하고 증류수에 보관한 뒤 24시간 후 부드러운 모를 가진 칫솔을 이용하여 칫솔질하였다. 각 시편을 인공우식용액에 48시간동안 침잠시켜 인공우식병소를 유발한 후 광밀도를 컴퓨터 영상분석 프로그램으로 분석하고 표면미세경도를 측정하여 다음의 결과를 얻었다. 1. 광밀도는 APF gel을 도포한 II군에 비해 불소 바니쉬를 도포한 III, IV군이 높았으나(p<0.05) III군과 IV군 사이의 유의한 차이는 없었다. 2. 표면미세경도는 IV군, III군, II군, I군의 순으로 높았다(p<0.05). 3. CavityShield™개를 도포한 IV군과 Fluor Protector^(??)를 도포한 III군은 광밀도에서는 유의한 차이가 없었으나 표면미세경도는 IV군이 III군보다 유의하게 높았다. 이상의 결과를 종합해 볼 때 불소 바니쉬가 APF gel에 비해 법랑질 탈회 억제 효과가 우수한 것으로 나타났다. 임상적용의 용이성과 안전성을 고려할 때 불소 바니쉬의 사용이 영유아나 장애인에게 유용할 것으로 사료된다. The purpose of this study was to evaluate the effect of fluonde varnish on prevention of enamel demineralization. Eighty bovine enamel blocks were divided randomly into 4 groups of 20 specimens: Group I served as the control with no topical application of fluoride. Group II was treated with APF gel for 4 minutes. Group III was treated with Fluor Protector^(??). Group IV was treated with CavityShield™. After 24 hours of treatment, samples were brushed with a soft bristled tooth brush to stimulate normal mechanical wear of varnish. Early caries lesions were produced by placing each specimen into demineralization solution at pH 4.0 for 48 hours. Then the optical density of the lesions was measured by light fluorescence induced by plasma light and the surface microhardness were measured by the vicker' s hardness test. The results were as follows: 1. The optical densities of group III, IV were significantly higher than that of group II, but no significant difference was noted between group III and IV. 2. The surface microhardness of group IV was the highest, followed by group III, II, and I(p<0.05). 3. There were no significant differences between group III and IV in optical density. However, the surface microhardness of group IV was significantly higher than that of group III. The results of present study indicate that the fluoride varnish is more effective than APF gel for prevention of dental caries.

『중소연구(中蘇硏究)』를 통해 본 한국에서의 중국 정치 연구

조영남 서울대학교 국제지역원 1997 국제지역연구 Vol.6 No.1

우리는 중구과 소련에 관한 대표적인 학술잡지인 『중소연구(Sino-Soviet Affairs)』를 검토함으로서 지난 20여 년 동안 한국에서 중국 연구가 어떻게 진행되었는가를 살펴볼 수 있다. 이에 대한 검토 내용을 정리하면 다음과 같다. 첫째, 연구 분야의 변화를 살펴보자. 한국에서의 중국 연구는 소련이나 한반도와 관련해서는 어느 정도 연구가 이루어졌지만, 중국을 동구나 아시아 사회주의 국가-베트남과 북한-와 비교 검토하는 연구가 매우 적었다. 따라서 우리는 이후에 연구 대상 국가의 다변화 즉 중국을 다른 사회주의 국가들과 비교연구하는 과제를 수행해야 한다. 또한 중국 그 자체에 대한 연구와 관련해서도 연구 분야의 다각화가 필요하다. 중국 연구는 주로 정치, 외교, 경제 분야에 집중되어 있고, 이에 비해 다른 분야는 상대적으로 소홀히 다루어졌다. 다음으로 중국 정치 연구는 지난 20여 년 동안 많은 발전-연구 분야의 다각화와 전문 연구자의 확충 등-을 이루었다. 그러나 여전히 해결해야 하는 연구 과제도 많다. 예를 들어, 중요한 정치적 사건-문화대혁명, 천안문 사건(1989년)에 대한 연구, 변화된 정치 구조에 대한 연구, 정책결정에 대한 연구, 소수민족문제에 대한 연구, 정치사상에 대한 연구 등도 필요하다. 둘째, 중국 정치를 연구하는 연구자를 살펴보자. 한국에서 중국 정치를 연구하는 연구자는 대개 미국, 한국, 대만-1980년대 중반 이전에는 주로 미국과 대만-에서 학문적인 훈련을 했다. 즉, 한국의 연구자들은 학문적 훈련이 다른 '집단'으로 구성되어 있다고 할 수 있다. 그런데 이런 연구 집단들은 지난 연구 과정에서 연구 접근법과 연구 주제 선택, 자료의 이용 면에서 차이를 보이면서, 서로 융합되기보다는 독자적인 흐름을 형성해왔다. 그 결과 한국에서의 중국 정치 연구는 어떤 하나의 뚜렷한 흐름을 형성할 수 없었다. 마지막으로, 중국 연구 방법론과 자료 이용에 대해 살펴보자. 한국에서 중국 정치를 연구하는 연구자들이 사용하는 방법론은 크게 두 가지로 즉, '전통적 방법론'-역사적, 서술적 접근법-과 '과학적 방법론'-사회과학적인 접근법-으로 나누어졌었다. 그리고 연구자들의 연구 방법론에 대한 고민은 아직까지 부족하다고 할 수 있다. 또 자료 이용과 관련해서는, 1980년대까지는 주로 미국의 연구서나 중국의 공식 간행물에 의존해서 연구를 수행했다. 이는 기본적으로중국 현지에 대한 접근이 어려웠던 상황-한국과 중국의 국교 수립은 1992년의 일이다-으로 인해 불가피한 것이었다고 할 수 있다. 그러나 그후 특히 1990년대 들어서는 현지 조사 작업 등을 통한 체계적인 자료 수집과 분석에 근거한 연구가 본격적으로 이루어지기 시작했다. This article evaluates the study of contemporary China in Korea for the last two decades. For this purpose, a critical review was conducted on the articles that appeared in Sino-Sovet Affairs, a leading journal in the field. The assessment was carried out in the following three aspects. First, withregard to the subject of inquiry, most of the articles evaluated studied China in its own right or focused on China's external relations with the Soviet Union and the Korean Peninsul. One important agenda for future research is to do comparative studies of China and other socialist states. Additionally, a predominant majority of the articles evaluted dealt mainly with political, economic and diplomatic issues, while largely neglecting other key themes of research. Furthermore, there is an acute need for more research on major events like the Cultural Revolution and the Tiananmen Incident. Second, the Korean community of contemporary China studies is best characterized by pluralism. In terms of backgrounds, scholars were trained mainly in the United States, Taiwan and Korea. And these differences contributed rather significantly to the variatoins in their approachese, use of source materials, and so on. How such a pluralistic approach will affect the process of knowledge accumulation in the field remains to be seen. Third, Korean scholars of contemporary China still seem to lack sufficient interest in the methodological issue. Generally speaking, traditional Sinological methods (historical and descriptive) continue to dominate over more "scientific" methods. With the diplomatic normalization with China, however, there seems to have been a significant increase in the extent to which primary data and fieldwork are utilized.

뇌졸중 환자의 경상운동이 상지기능에 미치는 영향

조영남,김홍근,권혁철 대구대학교 특수교육재활과학연구소 2008 再活科學硏究 Vol.26 No.2

경상운동은 다른 쪽의 신체에서 일어나는 의도된 움직임의 경상 반전으로 발생하는 한 쪽 신체의 무의식적인 운동이다. 본 연구는 뇌졸중으로 인한 편마비 환자에게서 나타나는 경상운동이 상지기능에 미치는 영향에 대해 알아보고자 하였다. 65명의 뇌졸중 환자를 대상으로 연구한 결과, 경상운동이 나타나지 않은 환자군의 상지기능은 경상운동이 나타난 환자군의 상지기능과 통계학적으로 유의한 차이를 보였으며, 경상운동이 나타난 환자군에 비해 상지기능이 좋은 것으로 나타났다. 또한, 경상운동이 나타나지 않은 환자군과 경상운동이 경한 환자군, 경상운동이 중한 환자군의 상지기능을 비교한 결과 경사운동이 적게 나타날수록 상지기능이 좋은 것으로 나타났다. 연구의 결과를 종합하여 볼 때, 뇌졸중으로 인한 편마비 환자에게서 나타나는 경상운동은 상지기능을 감소시키는 요인 될 수 있는 것으로 나타났다. The purpose of this study was to compare upper extremity's motor function according to the mirror movements in hemiparetic patients with stroke. Mirror movements are involuntary movements in one side of the body that occur as mirror reversals of the intended movement on the other side of the body. The subjects of the study were 65 stroke patients who were admitted from May, 2004 to April, 2005 in the Y University medical center. This study used the Manual Function Test(MFT) and the Purdue pegboard test to evaluate upper extremity‘s motor function. The severity of mirror movements were assessed according to the criteria of Woods and Teuber. The results of the study was as follow; First, The upper extremity‘s motor function in hemiparetic patients without mirror movements was significantly different in hemiparetic patients with mirror movements(p< .05). Second, The upper extremity's motor function in hemiparetic patients with mild mirror movements was significantly different in hemiparetic patients with severe mirror movements(p< .05). The result showed that the mirror movements in hemiparetic stroke patients are correlated with upper extremity's motor function and the severity of mirror movements affected upper extremity's motor function. 경상운동은 다른 쪽의 신체에서 일어나는 의도된 움직임의 경상 반전으로 발생하는 한 쪽 신체의 무의식적인 운동이다. 본 연구는 뇌졸중으로 인한 편마비 환자에게서 나타나는 경상운동이 상지기능에 미치는 영향에 대해 알아보고자 하였다. 65명의 뇌졸중 환자를 대상으로 연구한 결과, 경상운동이 나타나지 않은 환자군의 상지기능은 경상운동이 나타난 환자군의 상지기능과 통계학적으로 유의한 차이를 보였으며, 경상운동이 나타난 환자군에 비해 상지기능이 좋은 것으로 나타났다. 또한, 경상운동이 나타나지 않은 환자군과 경상운동이 경한 환자군, 경상운동이 중한 환자군의 상지기능을 비교한 결과 경사운동이 적게 나타날수록 상지기능이 좋은 것으로 나타났다. 연구의 결과를 종합하여 볼 때, 뇌졸중으로 인한 편마비 환자에게서 나타나는 경상운동은 상지기능을 감소시키는 요인 될 수 있는 것으로 나타났다.

매복된 하악 제1대구치의 외과적 노출술을 이용한 치험례

조윤정,박영옥,김태완,김현정,김영진,남순현 대한소아치과학회 2007 大韓小兒齒科學會誌 Vol.34 No.2

제1대구치는 저작과 혼합치열기 이후의 수직적 교합관계형성에 핵심적인 역할을 하고 악골의 성장발육에 관여한다. 제1대구치의 매복은 하안면 고경의 감소, 낭의 형성, 치관 주위염, 인접치의 치근 흡수, 부정 교합 등의 문제점을 야기할 수 있다. 치료방법으로는 주기적 관찰, 외과적 노출술, 교정적 견인, 외과적 재위치술, 발치 등이 있으며 이중 외과적 노출술이 가장 기본이 되는 술식이다. 외과적 노출술시에는 맹출로의 개방성을 유지하는 것이 중요하며 개방성을 유지시키기 위한 방법으로는 레진관의 접착, 산화 아연 유지놀 시멘트, 치주포대 등을 노출된 부위에 충전시키는 방법 등이 있다. 본 증례에서는 매복된 하악 제1대구치에서 장애물의 제거와 외과적 노출술을 시행한 결과 자발적인 맹출을 관찰할 수 있었다. 또한 surgical pack과 투명상유지장치를 사용하여 간편하고 효과적으로 맹출로의 개방성을 유지할 수 있었다.

한라산 혼파목초지에 있어서 억새 (Miscanthus sinensis)의 계절적 연차적 생육변화

조남기,김한림,고영희 제주대학교 1984 논문집 Vol.17 No.-

This study was conducted to examine the yearlv and seasonal changes of Miscanthus sinensis on the improved pasture of the mountain districts around Mt. Halla in Cheju Island. For this study, the researcher had investigated for six years from 1977 to 1982 the improved pasture which had been used for grazing from 1977 to 1982. The pasture was reclaimed from native grassland. The mixed seeds of 17 kgs' Dacrylis glomerata, 7 kgs' Festuca arundinacea, 2 kgs' Lolium multiflorum and 2 kgs' Trfolium repens were sowed per 1 ha. The results of this study are the following; 1. The seasonal changes of Miscanthus sinensis: its length, weight, density and coverage are heighest in Autumn, and are lowest in Spring every year. 2. The yearly change in the length of Miscanthus sinensis: its length is gradually increased from 46.19cm in the first year after the reclaimation to 58.81 cm in the 6th year. This change can be represented by the regression equation, y=1.10x^(2)+l.96x +44.02. 3. The yearly change in its density: its density is rapidly increased from 0.06% in the first year to 0.72% in the sixth year. The results of this change can be obtained with the regreuion equation, y=0.04x^(2)-0.11x + 0.07. 4. The yearly change in the coverage: its coverage is increased year by year from 0.34% in the first year to 5.67% in the sixth year. This change can be calculated with regression equation, y=0.18x^(2) + 0.12x-0.42. 5. The yearly change in its weight: the weight is also increased year after year from 7.98 kg in the first year after reclaimation to 130.04kg in the sixth year. This change can be calculated with the regression equation of y=5.88x^(2)-15.27x + 15.24.
