This study is an attempt to evaluate the use of an oral contraceptive by: 1. Deforming the acceptance rate of the oral contraceptive according to socio-demographic characteristics 5. Estimating the duration of the use of the contraceptive f. Discovering reasons why the contraceptive was discontinued 4. Computing the cumulative continuation and discontinuation rate according to socio-demographic characteristics, history of pregnancies, and attitude of husband at the time of selection of the contraceptive. One hundred sixty-eight women of child bearing age (14-49 years), residing in Yonhee Dong, Seoul, Korea and registered as oral contraceptive accepters at Yonsei Community Health Center, were interviewed during a three week period in 1973. The questionnaire was designed to determine the socio-demographic characteristics of the oral contraceptive accepters, the current status of their family planning practice, medical reactions if any, discontinuation practice, and the duration of the use of the contraceptive. The major findings of the study were as follows; 1. The acceptance rate was highest for women between 30 and 34 years of age, the mean age being 34.4 years. 2. Fifty six point five percent of all respondents said that thirty years of age was the ideal age to stop having children. 3. The average number of living children was 3.5 and fifty four point eight percent of respondents felt 2 boys and I girl was the ideal number of children. 4. The average number of pregnancies was 5.2 and the average number of induced abortion was I. 4. 5. Fifty eight point eight percent of the respondents had experience in the use of contraceptive methods in the past. 6. Forty one point seven percent of the respondents replied that they chose the oral contraceptive because, "it was not complicated to use." 7. Sixty four point eight percent of the women said their husband approved of their taking the pill. 8. The cumulative discontinuation rate was sixty point five percent of the total respondents for one year in first segment. 9. Sixty six point nine percent of the respondents had experienced side-effect while using the pill. The side effects for 68.9 percent of these women were castro-intestinal upsets. Twenty point eight percent of the women who had side effects consulted with medical personnel about them. Women who had more education had more side effects. 10. Seventy three point two percent of the women who discontinued the pill did so because of medical reasons. Women who were younger discontinued the pill for personal reasons more-often than older women. Among personal reasons listed for discontinuing the pill was the attitude of the husband. 11. The average duration of continuance of the contraceptive was 5.3 cycles under 29 years of age; 7.4 cycles between 30 and 34 years of age; and 8.4 cycles over 40 years of age. 12. The discontinuation rate was seem to increase sharply in the early cycle and increase more slowly in later cycle. Conclusions and suggestions: Since the attitude of the husband was shown to be important, the current family planning program should be expended to include approach to husband. For women who must use the oral contraceptive, education and support must be enhanced so that the discontinuation rate due to side effects will be decreased.

The survey on dental health condition and eating habit of local residents in Daegu and Kyungbuk had been conducted. Through the analysis of influence of dental health condition on eating habit I could get the following result. The number of subjects of survey is 630. The period of survey is from June 2006 to September 2006. 1. General quality of subjects is that forty-four point four percent of subjects are male and fiftyfive pointsix percent are female. The age of thirty point one percent of subjects is between 20 and 29. Fifty-six point two percent of subjects are married. Fifty-one point four percent of subjects have above bachelor degree. Monthly income of forty-four point eight percent of subjects is less than one million won. Twenty-four point four percent of subjects are students. Fifty-five point seven percent of subjects are living in big cities. 2. Forty-seven point seven percent of male and fifty-one point eight percent of female answered their subjective dental health condition is bad. Marital status, age and academic background have relationship with answer. Forty-three point nine percent of married subjects and forty-one point five percent of divorced or bereaved subjects said they have bad dental health condition. The older he is or the lower academic background he has subjects think they have bad dental health condition. Forty-seven point four percent of non-educated subjects answered their dental health condition is bad. Forty-six percent of self-employed subjects and subjects who live in the country have tendency to think their dental health condition is bad. 3. About eating habit knowledge, male's knowledge of 2.03$\pm$0.20 is lower than female's of 2.08$\pm$0.21. This shows there is statistically significant difference(p<0.01). 4. There is significant relationship between subjective dental health condition and health condition of subjective. This means subject who has better health condition has also better dental health condition(37.5%). About subjective dental health condition, subject who eats restoratives has worse dental health condition. This shows there is a relationship between dental health condition and eating restoratives(p=0.004) and subject who works out steadily has better dental condition. 5. About relation between dental health condition and eating habit, subject who eats vegetables has worse dental health condition by fifty point seven percent. As cross tabulation result, p-value is 0.002. In level of significance of 0.05, there is statistically significant difference in eating habit. 6. It seems that eating habit has an effect on marital status, age, academic background, income and also on dental prosthetic treatment situation. Many subjects think their dental health condition is bad. About eating habit, subjects who eat meat have better dental health condition. Subjects who drink green tea and fruit juice has better dental health condition than who drink coffee and Balanced diet is good for dental health condition. As eating habit is important for developing dental health, government should make a proper program. Dental health education program especially for elderly, low-eduacted, residents in the country and poor people should be developed. Government, dental health organization, dental health specialist, associated research institution and people work in the press should be concerned and devote to improve quality of life. Primary prevention education will help for dental health.

본 논문은 필자가 미국 미쉬간대학에 유학중 실시된 연구로서 동대학 목재가공학과에 설치된 소형 목재인공건조장치를 사용하여 일정한 건조조건(건구 온도 $150^{\circ}F{\risingdotseq}65.5^{\circ}C$, 습구온도 $1250^{\circ}F{\risingdotseq}51.7^{\circ}C$, 관계습도 48%, 평형함수율 6.9%)하에 공기 순환속도를 매분당 250ft., 400ft, 및 650ft.로 변경할 때 얻어지는 건조속도를 측정하고, 시간당 건조율을 산출하여 비교 검토한 것이다. 본 실험에 사용한 수종은 북미산소나무 Northern white pine (Pinus strobus L.)로서 시편의 크기는 길이 60cm, 넓이 12.5mm(5in.), 두께 18.7mm(3/4in.)이며 공시목의 표면은 증발조건을 균일히 하기 위하여 포삭하였으며, 마구리(end grain)에는 end coating 하였다. 또한 공기순환속도 측정은 상기대학에 비치된 velometer를 사용하였다. 1. 목재의 섬유포화점(함수율 30%) 이상에 있어서 공시목의 건조율은 건조실내 공기순환속도의 증가에 따라서 증가된다. 즉 공시목의 건조율 증감은 공기 순환속도에 대략 비례한다. 그러나 섬유포화점 이하에 있어서는 공기순환속도의 증강은 건조율 증감에 거의 영향을 이치지 아니한다(그림 1, 2 참조). 2. 실험한 건조조건하에 있어서는 공시목의 초기 함수율이 높을수록 높은 건조율을 얻을 수 있다. 즉 공시목의 초기 함수율(MC30% 이상)이 동일하지 아니한 경우에도 공기순환속도를 증가하면 건조 최종기에 있어서 비교적 빨리 대체로 같은 함수율의 공시목을 얻을 수 있다(실험한 초기 함수율, 건조조건 및 공기순환 속도등은 심한 건조 결함을 유발하지 아니하였음). 3. 본연구 결과에 의하면 공시목의 건조율은 섬유포화점(대략 MC30%)에 있어서 현저한 변화를 나타내고 있다. 즉 공시목의 함수율에 대한 건조율 곡선은 그림 3으로 표시된 바와 같이 섬유포화점 이상에 있어서는 건조율 곡선은 X축(MC)에 대하여 요(凹)형(concave)을 나타냈는데, 섬유포화점 이하의 함수율 범위 30%에서 20%에 있어서는 건조율 곡선은 X축에 대하여 철(凸)형(convex)을 나타냈으며 함수율 20% 이하에 있어서는 재차 심한 요(凹)형을 나타내고 있음을 알 수 있다. 이와감은 결과를 요약표시한 원문 그림4에 있어서, 건조율 곡선의 반곡점은 대략 섬유포화점인 MC 30%와 MC 20%에 위치하고 있음을 알 수 있다. 이와같이 섬유 포화점으로 알려져 있는 MC 30%와 20%에 있어서 건조율이 급변하는 반곡점 즉 한계점을 표시하는 것은 다음과 같은 야유에 의한 것으로 고려된다. 즉 세포막에 흡수된 결합수의 증발은 세포강, 세포간격 및 기타의 미세한 공간에 존재하는 자유수의 증발보다 훨씬 곤란하므로, 함수율 30%에서 20%의 범위에 있어서는 철(凸)형을 나타낸다. 즉 함수율 30%에서 20% 의 범위에 있에서 세포막의 모세관 응축수(capillary-condensed water)의 증발은 대략 동일한 감소율을 나타내나, 공시목의 함수율이 20%에 접근됨에 따라서 한층 강한 결합상태하에 있는 수분(표면 결합수 및 그 부근에 있는 수분)이 증발하게 되나, 그와 같은 수분의 증발은 한층 곤란하므로 함수율 20% 이하에 있어서 건조율곡선은 재차 요(凹)형을 표시하는 것으로 사료된다. 이상의 관계를 요약 표시한 원문 그림 4에 있어서, 반곡점을 가지지 아니한 점선 곡선 AC 와 2개의 반곡점을 가지는 실선곡선 BD를 비교하면, BD곡선은 AC곡선보다 함수율범위 30%에서 20%에 있어서 그 건조율은 현저히 감소되고 또한 D점을 반곡점으로 해서 그 건조율은 가일층 감소되고 있음을 알 수 있다. 이상을 요약하면 생재에서 함수율 30%(섬유포화점)까지는 큰 건조율을 표시하니 함수율 범위 30%에서 20%에 있어서는 그 건조율은 점감되고 함수율 20% 이하에 있어서는 그 건조율은 현저히 감소됨을 표시한다.

The Survey of Teaching Practice and the Factors of Satisfaction on Teaching Practice in Home economics Education The purpose of this study was to investigate teaching practice and factors on satisfaction of educational practice in home economics education of middle and high school, to provide information for improving educational practice. The subjects were 365 college students who had the educational practice in 1999. A questionnaire was used. The results were as follows: 1. Seventy on point eight percent of the subjects choose their teaching-practice school by themselves, however 25.2% of them was recommended by college. Twenty five point six percent of the subjects satisfied the orientation of the college, but 32.8% of them didn’t. Thirty four point four percent of the subjects indicated the form of practice documents was good, whereas 27.9% of them it needed more improvement. 2. Fifty four point eight percent of the subjects used their own research room. The orientation of teaching-practice school was good(36.4%) but 20.0% of the subjects dissatisfied. Eighty nine percent of the subjects managed the class as vice supervisory teachers, 46^ of them had example instruction, the number of subjects practised at middle school and public school were more than high school and private school respectively. 3. The score of educational expertise of teachers was 3.66 and the teacher educators’was 3.85 The score of educational expertise of the teacher educators who were in college of education(3.87) was higher than in general teacher course(3.77) at p$\leq$0.05 4. The score of educational practice satisfaction in the all subjects was 3.67. The factors to effect the satisfaction of the educational practice were the kind of research room, the orientation plan of the practice school and the management of the class, The score of the educational practice satisfaction was correlated with the score of educational expertise of teachers and teacher educators. and the agrresive attitude to the teaching practice of the teacher educators.

Experimental investigation into the behaviour of half-scale brick masonry panels were conducted under cyclic loading normal to the bed joint and parallel to the bed joint. For each cycle, full reloading was performed with the cycle peaks coinciding approximately with the envelope curve. Unloading, however, was carried out fully to zero stress level and partially to two different stress levels of 25 percent and 50 percent of peak stress. Stability point limit exhibits a unique stress-strain curve for full unloading but it could not be established for partial unloading. Common point limit was established for all unloading-reloading patterns considered, but its location depends on the stress level at which unloading is carried to. Common point curves were found to follow an exponential formula, while residual strains versus envelope strains can be expressed by a polynomial function of a single term. The relation between residual strain and envelope strain can be used to determine the stress level at which deterioration due to cyclic loading began.

This study was performed to investigate nurses’ perception for nutrition education. The subjects of this study were 197 nurses and 94 nursing assistants working at hospitals in the Kyung-nam area. The survey was conducted by using a self-administered questionnaire in November, 2001. The results were as follows : Sixty-seven point seven percent of the subjects were nurse, 32.3% were nursing assistant. Average age of subjects was 26.9 years old, average nursing experience was 5.7 years, and 70.7% of the subjects graduated from a junior college. The average nutrition knowledge score was 14.3$\pm$2.5 out of possible 20 points. Seventy-four point two percent of the subject responded that nutrition education is very necessary for patient, and positive responses in the nurse were higher than that nursing assistant(p<0.001). Only 8.6% of the subjects had nutrition education training. The perceptions about a suitable person for nutrition counseling and nutrition education indicated dietitian(69.3%) and nurse(21.3%). Fifty-two point eight percent of the subjects responded that they would not participate in nutrition education themselves and the main reason for this was that they believed lack of expert knowledge(43.4%), and that such courses should be taught by specialist(40.5%). Forty-eight point eight percent of subjects had nutrition counseling experience for patient, and nurses, married nurses and those over 2 years of nursing careers had significantly higher nutrition counseling experience for patient than nursing assistant, unmarried nurses and those under 2 years of nursing careers(p<0.05-p<0.001)
