  • 간벌과 수형조절이 종자생산량을 증가시키므로 이로 인해 잣 종자의 성분에 어떠한 영향을 끼치는지에 대하여 알아보기 위해 각 처리별(간벌목, 무간벌목, 채종목, 1m 단간목 및 2m 단간목)로 종자성분 분석을 실시한 결과는 다음과 같다. (1) 간벌목과 무간별목의 일반성분(수분, 회분, 조지방 및 조단백질)은 두 처리간 유의성이 인정되지 않아 간벌이 종자의 성분에 영향을 주지 않는 것으로 나타났으며, 채종목과 수형조절목(1m 단간목, 2m 단간목)의 일반성분 역시 두 처리간 유의성이 인정되지 않아 수형조절 또한 종자의 성분에 영향을 주지 않는 것으로 나타났다. (2) 간벌목과 무간별목의 지방산 분석은 함유량의 대부분(94% 이상)을 차지하는 Linoleic acid(18:2), Oleic acid(18:1), Palmitic acid(16:0)가 처리간 유의성이 인정되지 않았고, 필수지방산 2종을 모두 함유하고 있어 간벌은 잣 종자의 지방산 함량에 영향을 주지 않는 것으로 나타났으며, 채종목과 수형조절목의 지방산 역시 함유량의 대부분(93% 이상)을 차지하는 Linoleic acid(18:2), Oleic acid(18:1), Palmitic acid(16:0)가 처리간 유의성이 인정되지 않았으며, 필수지방산 2종을 모두 함유하고 있어 수형조절은 잣 종자의 지방산 함량에 영향을 주지 않는 것으로 나타났다 따라서 간별과 수형조절에 따른 구과 생산량의 증대는 종자의 일반성분과 지방산 함량에 영향을 주지 않는 것으로 사료된다.

  • 연구목적: 본 연구는 machined 임플란트와 골유도능이 있는 calcium phosphate를 electron-beam deposition으로 coating처리한 임플란트의 골/임플란트 접촉률을 조직형태계측학적으로 비교하는 것이다. 연구 재료 및 방법:여섯 마리의 수컷 New Zealand white rabbit과직경3.3 mm, 길이 5 mm의 임플란트 24개를 준비하였다. Machined 임플란트 (대조군)와 calcium phosphate coated 임플란트(실험군)를 좌, 우 경골에 2개씩 총 4개를 식립하고 임플란트 주위에 부하가 가해지지 않도록 하여 3주, 6주의 치유기간을 두었다. 식립 3주와 6주후, 각각 3마리의 토끼를 희생하여 조직시편을 제작하였다. 제작된 시편을 광학현미경 하에서 골/임플란트 접촉률 (BIC ratio)을 계산하고 paired t-test로 두 군을 비교하였다. 결과:골/임플란트 접촉률은 임플란트 식립 3주후, 대조군에서 평균과 표준편차는$44.1{\pm}16.5%$ 이었고 실험군은 $70.8{\pm}18.9%$로 실험군이 통계적으로 유의하게 높았다 (P= 0.0264). 6주후의경우, machined 임플란트는 $78.6{\pm}15.1%$, calcium phosphate coated 임플란트는 $79.0{\pm}26.0%$로 두 군 간 통계적으로 유의한 차이는 없었다. 결론: Calcium phosphate coated 임플란트는 machined 티타늄 임플란트에 비해 빠른 초기 골반응을 나타냈다. 그러므로, 임상적으로 calcium phosphate coated 임플란트를 사용했을 때, 수술 후 치유 기간을 단축하여 조기 부하가 가능할 것으로 사료된다.

  • The family value is expected to play a crucial role in adjusting a new environment for the family, especially in the critical situation as having a child with cancer in the family. The purpose of the study was to analyze the family values of the family with cancer children in order to offer descriptive data, which will facilitate family adjustment with cancer children. The survey was conducted from July 18, 2000 to August 30, 2000 and the analysis included 309 parents of the children who have been diagnosed as cancer, 18 years of age or less, and treated either hospitalized or at the outpatient clinics. Two instruments were used to measure family value. The modified form of General family value scale was 18 items with a 5 points of Likert response format (Cronbach alpha= .78) and Family value scale was developed for the study with 12 items on a 5 points of Likert response format(Cronbach alpha= .73). The data analysis utilized SAS 6.12 for percentage, frequency, Mean, and t-test of demographic characteristics and mean, F score, ANOVA, and Duncan follow-up test of variable relationships. The study findings were as follows. 1) In General family value, the fathers gave the higher scores to 'The children should live with their parents'(M=4.01), and 'A parents and their children are like one body' (M=3.91). The item with lowest score was 'Its not impossible for man to have extramarital relationship'(M=1.92). The mothers thought the most important items were 'A parents and their children are like one body'(M=3.79), and 'A wife needs to be patient to keep harmony of the family' (M=3.56), and the item with lowest score was 'Its not impossible for man to have extramarital relationship'(M=1.44). 2) The mean scores of the mothers were higher than the fathers for all items in family value with cancer children, while fathers gave more points for items in general family value. Both of parents gave the highest score to 'The health of the family is most important to me'(M=4.85 for fathers, M=4.97 for mothers), and followed by 'The husband and wife need to be patient and understand each other to overcome the difficulties'. The item with lowest scores was 'The parents can have conflicts in making decisions since their child was sick'(M=3.34 for fathers, M=3.37 for mothers). 3) There were significant differences between fathers and mothers in items of General family value; fathers gave more points to the items of 'The children should live with their parents', 'Its essential to hold the ceremony to respect their forefathers', 'Its not impossible for man to have extramarital relationship', 'A woman with two daughters should have one more baby to succeed the generation', 'The husbands are responsible for the household economy', and 'When his mother and wife dont get along, the man should be on his mothers side'. However, there was no significant difference between fathers and mothers in items of Family value with cancer children. 4) The general family value was significantly different by the birth order of cancer children, mothers age, mothers education level, and types of payment. On the other hand, the family value with cancer children was significantly different by the age of cancer children, period of illness, period after completing treatment, family type, the number of family members, and the number of total children.

  • Health education, as the most fundamental concept for national health promotion, alms for developing the self-care ability of the general public. High school days are regarded as the period when most important physical, mental and social developments occur, and most health-related behaviors are formed. School health education is one of the major learning resources influencing health potential in the home and community as well as for the individual student. High school health education in Korea has a fundamental systemic flaw in that health-related subjects are divided and taught under various subjects areas at school. In order to achieve the goal of school health education, it is essential to make a systematic assessment of the learner's concerns connected with his health and life, and the factors affecting them. So far, most of the research projects that had been carried out for improving high school health education were limited in their concerns to a particular aspect of health. Even though some had been done in view of comprehensive school health education, they failed to Include a health assessment of the learner. Therefore, in this study the high school students' concerns related to health and life were investigated in the first place on the basis of the PRECEDE model, developed by Green and others for the purpose of a comprehensive diagnostic research on high school health education. This study was done in two steps : one was the basic study for developing research instrument and the other was the main one. The former was conducted at five high schools in Seoul and Cheongju for 2 months-beginning in March, 1996. The students were asked to respond to questions related to their health and lives in unstructured open-ended question forms. On the basis of analysis of the basic study, the diagnostic instruments for the quality of life, health problems, health behavior and educational factors were constructed to be used for the collection of data for main study. An expert panel and the pilot study were used to improve content validity and reliability of the instruments. The reliability of the instruments was measured at between .7697 and .9611 by the Cronbach $\alpha$. The data for this study were collected from the sample consisted of the junior and senior classes of twenty general and vocational high schools in Seoul and Cheongju for two months period beginning in July, 1996. In analyzing the data, both t-test and $X^2$-test were done by using SAS-$PC^+$ Program to compare data between the sexes of the high school students and the types of high school. A canonical correlation analysis was carried out to determine the relationships among the diagnostic variables, and a multivariate multiple regression analysis was conducted by using LISREL 8.03 to ascertain the influences of variables on the high school students' health and quality of life. The results were as follows : 1) The findings of the hypothesis tests (1) The canonical correlation between the educational diagnosis variables and behavioral, epidemiological, social diagnosis variables was .7221, which was significant at the level of p<.001. (2) The canonical correlation between the educational diagnosis variables and the behavior variables was .6851, which also was significant (p<.001). (3) The canonical correlation between the behavioral diagnosis variables and the epidemiological variables was 4295, which was significant (p<.001). (4) The canonical correlation between the epidemiological diagnosis variables and the social variables was .6005, which was also significant (p<.001). Therefore, the relationship between each diagnosis variable suggested by the PRECEDE model had been experimentally proven to be valid, supporting the conceptual framework of the study as appropriate for assessing the multi-dimensional factors affecting high school students' health and quality of life. Health behavior self-efficacy, the level of parents' interest and knowledge of health, and the level of the perception of school health education, all of which are the educational diagnostic variables, are the most influential variables in students' health and quality of life. In particular, health behavior self-efficacy, a causative factor, was one of the main influential variables in their health and quality of life. Other diagnostic variables suggested in the steps of the PRECEDE model were found to have reciprocal relations rather than a unidirectional causative relationship. The significance of this research is that it has diagnosed the needs of high school health education by the learner-centered assessment of variety of factors related to the health and the life of the students. This research findings suggest an integrated system of school health education to be contrived to enhance the effectiveness of the education by strengthening the influential factors such as self-efficacy to improve the health and quality of the lives of high school students.

  • The purpose of this study was to examine factors influencing the meaning of life for middle-aged women. The subjects for the study were 190 middle-aged women who live in Busan. Data were collected from May 25 to June 20, 1999. The instruments for this study were as follows : the meaning of life scale developed by Jung D. R(1978) ; the self-esteem scale developed by Ro, E. Y, Kwon, J. H.(1997) ; the volunteer activity scale developed by Park G. J.(1999), the marital satisfaction scale developed by Choi G. Y.(1999) ; and the health status scale developed by Kim S. Y. (1991). SPSS PC+ was utilized for data analysis. Data were analysed according to frequency and percentage, mean and standard deviation, t-test, ANOVA, Sheffe' s test and Pearson' s correlation coefficients and stepwise multiple regression. The reliability of the tools was tested by Cronbach's $\alpha$ : and it showed reliability scores of 0.88(for the meaning of life tool), 0.81(for the self-esteem tool), 0.94(for the marital satisfaction tool) and 0.78(for the health status tool).

(2000): characteristics and diagnosis, influence on pregnancy, goal and method of management, diet therapy, exercise therapy, insulin therapy, hypoglycemia and hyperglycemia and postpartum care of GDM. The data were analyzed by SAS program for t-test, ANOVA and Scheffe test. The results were as follows: 1. The mean score of knowledge on GDM was 23.18. 2. There were significant differences according to age(p= 0.002), education background (p= 0.045). working period(p= 0.000), working unit(p= 0000), working experience of obstetric and gynecologic (OS & GY) units(p= 0.000), experience of pregnancy (p=0.003) and experience of delivery (p=0.014) in GDM knowledge. 3. The level of each area on GDM knowledge was as follows; 1) Area of characteristics and diagnosis of GDM The mean score of this area was 0.79. Nurses' knowledges were significantly different by age(p=0.003), marital status (p=0.018), working period(p=0.002) working unit(p=0.007), working experience of OB & GY units(p=0.005), experience of pregnancy(p=0.034) and experience of delivery(p=0.033). 2) Area of influence on pregnancy The mean score of this area was 0.93. Nurses' knowledges were significantly different by age(p=0.006), working unit (p=0.000) and working experience of OB & GY units(p= 0.000). 3) Area of goal and method of management The mean score of this area was 0.70. Nurses' knowledges were significantly different by age(p=0.004), region(p=0.006), education background(p=0.013), marital status(p=0.007), working period(p=0.000), working unit(p=0.011), working experience of OB & GY units(p=0.002), experience of pregnancy(p=0.025) and experience of delivery(p=0.043). 4) Area of diet therapy. The mean score of this area was 0.74. Nurses' knowledges were significantly different by age(p=0.002), region(p=0.011), marital status (p=0.001). working period (p=0.007). working unit(p=0.002), working experience of OB & GY units(p=0.001), experience of pregnancy(p=0.001), experience of delivery(p=0.011) and diabetes patients in family members(p=0.032). 5) Area of exercise therapy. The mean score of this area was 0.83. There were not significant differences in all general characteristics. 6) Area of insulin therapy The mean score of this area was 0.61. Nurses' knowledges were significant differences by age (p=0.024), marital status (p=0.048), working period(p=0.027), working unit(p=0.002), working experience of OB & GY units(p=0.000), experience of pregnancy (p=0.047) and experience of delivery(p=0.040). 7) Area of hypoglycemia and hyperglycemia. The mean score of this area was 0.83. Nurses' knowledges were significantly different by marital status (p=0.027), working period(p=0.001). experience of pregnancy(p=0.020) and experience of delivery(p=0.010). 8) Area of postpartum care The mean score of this area was 0.69. Nurses' knowledges were significantly different by working unit(p=0.000), working experience of OB & GY units (p=0.000) and working experience of medical unit(p=0.047). The results of this study are suggested that nurses might be taught systemically and individually about GDM so that they can become more proficient in detecting and preventing GDM, and therefore they will feel confident to teach GDM to women.
