The purpose of the survey was to identify the degree and the relationship of sexual knowledge, sexual attitude. This information will provide useful data for a more systematic, desirable, and practical sex education. The data was collected from 187 first grade schoolchildren(95 boys and 92 girls) of two Junior high school in Chun-nam area. The data was gathered by questionnaire from Oct. 1 to 15, 1996. The questionnaire was modified by authors using the questionnaire developed by You-Jeong, Han(1996). Data was analyzed by using the statistical computer package, SAS to manipulate the data long with percentages, means, standard deviation, t-test, chi2-test, GLM, and Pearson correlation coeffiency. The results in this study were summarized as follows : 1. Sex related knowledge. - The mean score of sex related knowledges showed significant differences between boys and girls(boys ; 22.3, girls ; 21.0, p<0.025), and in the area of pregnancy & delivery(boy ; 9.4, girls ; 7.9, P<0.000) showed significant difference between boys and girls, but in the area of physical differences of the others sex(boys ; 12.9, girls ; 13.1, p<0.551) showed no significant difference between boys and girls. 2. Sex related attitudes. - The mean score of sex related attitudes showed significant difference between boys and girls(boys ; 56.7, girls : 60.5, p<0.002) and in the area of psychological difference the other sex(boys : 28.9, girls : 32.5, p<0.000), but in the areas of form of friendship with the other sex(boys : 11.5, girls : 11.2, p<0.335), sexual delinquency & its prevention(boys : 16.3, girls : 16.9, p<0.171) showed no significant difference between boys and girls. 3. The relationships between sex related knowledges and sex related attitudes. - Those who had higher sex related knowledges showed more positive attitudes towards sex, and showed no statistical significance(r=0.08, p<0.286). 4. Differences of the sex related knowledges according to general characteristics. - The students had disease experience, health interest and more school performance had higher knowledge scores about sex. 5. Differences of the sex related attitudes according to general characteristics. - Those who were in high school performance had higher attitude scores about sex as well.. From the result of the study, it is recommended to develop systematic sex education through formal school education according to age.

OBJECTIVES: This study is to see the transition and pattern of the industrial iureal worker, and to develop the prediction model. METHODS: The data of the study are based on the samples from data-warehouse of Occupational Safety & Health Research Institute and are summed monthly from Jan 1986 to Dec 1999. This study data used data mart and Meta data from DW in KOSHA. The prediction model of the injured worker in Industry is designed by using a winters time series method after data preparing (i. e. sample, explore, modify) from DW. RESULTS: Thls predicted model obtained Winters-method multiplicative in exponential smoothing among applied all models, after the tlme series (total 163 months). It showed that the prediction power was 95.5 %. CONCLUSIONS: In the process of exploring the data, totally the rate of industrial injureal workers reduced, and in the yearly circulation, in February and September the number is the lowest but in June, July, October and November the higher. The number of monthly average injureal workers is 8709 (95 % confidence interval 8277, 9140). From the developed prediction model, since Aug 1999 the industrial injureal worker reduced rapidly in Dec 1999 and first period of 2000. But In second period of 2000 the number of the injured workers is increasing. To conclude, as the total economic situation is becoming better in 2000 than In 1999, its is supposed that the injured workers will increase more than the predictive injured workers because of the increase of production rate and labor force.

This study was conducted to identify the effect on the weight control of the REBT group program as a nursing intervention. For this purpose, non-equivalent control group design with pretest and posttest and follow-up test as quasi-experiment was used. Subjects of the study were consisted of twenty-four obese girls (Experimental group: 10, control group: 14) who appeared to having above 20% of the body mass index from ane high school in M city. The whole program was carried out from January to June, 2000. Used dependent variables for evaluating the effect of the REBT group program including were weight control belief(rational thinking, emotion about exercise, eating self-efficacy, eating behavior), body mass index and serum lipids(total cholesterol, triglyceride, low-density lipoprotein, high-density lipoprotein). For evaluating the effect of the program, dependent variables was analyzed by experimental stages three times; the first week, the fourth week, and the eighth week since the experimental input began. Data were analyzed by the SAS PC+ program with t-test, repeated measure ANOVA to determine the effect of program. The results of this study can be summarized as follows; 1. After the REBT group program, only eating self-efficacy among the weight control belief of experimental group was significantly increased than that of control group. 2. After the REBT group program, body mass index of experiment group was significantly decreased than that of control group. 3. After the REBT group program, triglyceride and low density lipoprotein among the serum lipids in the experiment group were significantly decreased than those of control group.

The use of communication media suitable for the audience and message is important in conducting effective family planning IEC activities. This study 'intended to assess differential effects of various media used by the Korean program on rural women's family planning knowledge, attitude, and practice. Data for the study were collected originally for the study of family planning mothers' clubs by the School of Public Health, Seoul National University in 1973. The sample was drawn according to the principle usually employed in obtaining a small sample from a large area. Initially, a sample of 25 Gun's was selected from a total of 138 Gun's by systematic random sampling on the basis of the list of number of mother's clubs in each Gun. Secondly, from each of these primary units(Gun) selected, two second stage units(Myon) were drawn by a systematic random sampling method based on the list of the number of Li's -in each Myon. Finally, a sample of nine Li's was drawn by a simple random sampling method from each Myon selected in the second stage sampling. In this way, a total of 450 Li's, 18 Li's from each of 25 Gun's, were selected. In one of thess 18 Li's of each Gun, all the married women with a living husband, up to age 49, were interviewed. out of 1.052 women interviewed, 145 women were naturally sterile or beyond menopause, and were excluded from thib study. Thus, the analytical population consists of 90 fecundable wives, including those with tubal ligation. A series of analyses were made to examine the relationships between family planning status and selected socio-demographic and communication variables. The family planning status was measured by three indicators, one for each of family planning knowledge, attitude, and practice. The variable for family planning knowledge was created by classifying the respondents into two groups: 1) those who professed to know in detail at least one contraceptive method out of a total of five, including the loop, oral pill, vasectomy, condom, and rhythm, and 2) those who had no professed knowledge about any method. The variable for family planning attitude was dichotomized into those who had favorable attitude toward at least one method among the same list of five, and those who did not have a favorable attitude toward any method. Contraceptive status was classified into two categories of current users and non-users. The independent variables, applied to explain the family planning status, include four sociode-mographie variables and six communication variables. The socio-demographic variables are age, education, number of living children and sons, and ideal number of sons. Communication variables are frequency of exposure to family planning messages through each of the following channels: radio and/or TV, newspaper and/or magazine, 'Happy Home' and/or leaflet, public meeting and/or lecture, family planning worker, and neighbor. Major findings obtained from the analysis are summarized as follows: 1. It was observed that about 33% of the eligible women did not want to have additional children but were not practicing contraception(pong-eem). About half of these women were ever-users and the other half were never-users. They have at least perceived the need for family planning, and thus, should be a primary target population for family planning IEC activities. 2. Socio-demographic variables showed a'closer association with practice than with knowledge or attitude. 3. The communication variables affected family planning status over and above the effects of the socio-demographic variables. When the communication variables were added to the socio-demographic variables as independent variables in the multiple classification analysis, the explained variance was increased by 6.3% in knowledge, 8.7% in attitude, and 4.3% in practice. This also suggests that the communication variables exert larger effects on knowledge and attitude than on practice. Family planning adoption decisions may be influenced by many other factors as well as by family planning knowledge and attitude. 4. The Beta-coefficient was computed for each of the independent variables in multiple classification analysis. Among the media considered in this study, 1) neighborhood communication, radio and/or TV, and 'Happy Home' and/or leaflet had significant effect on family planning knowledge:2) public meetings and/or lecture, radio and/or TV, and neighborhood communication had significant effect on family planning attitude: and 3) radio and/or TV, Happy Home and/or leaflet, and home visit had significant effect on family planning practice. Although program media, neighborhood communication, and radio and/or TV appeared to be more effective than other media, no definite pattern emerged. In the interpretation of these data, however, it should be remembered tha t the frequency of contact varies with the media. 5. When women were exposed to family planning messages more frequently, they tended to have more detailed knowledge about, and more favorable attitudes toward family planning, and were more likely to he practicing family planning. 6. Media behavior differed with age and educational level. It was found that the younger the women and the higher their educational level, the more frequently they were exposed to family planning messages through radio, TV, or printed materials. On the other hand, the older the women and the lower their educational level, the more frequently they were exposed to family planning messages through meetings, home visits, and neighborhood communication. This implies that the audiences' characteristics, such as age and educational level, should be taken into account in the selection of appropriate media.

The purpose of the study is to understand the types and the features of the health behavior of middle-aged women in the Middle East using Q-methodology. A survey was carried out during the period from the 1st of October to the 30th of December, 2006. Data for thirty five (35) women out of forty-nine (49) were analyzed through Principal Component Analysis and WRAP (Weighted Rotational Analytical Procedure). Analysis results showed that the group was divided into four types: Type I is health management; Type II is social activity; Type III is exercise orientation; and Type IV is religious dependency. Types I, II, and III were in a positive correlation with one another, and Type IV was not correlated with the other types. Subjective perception on the health behavior of middle-aged women in the Middle East (Jordan) was investigated and compared with middle-aged Korean women. The results of this study may provide more effective ways to improve the condition of health management and to promote the quality of life.

Ecologic studies are widely used in all fields of public health on account of accesibility of data. However, two problems related to these studies have been brought up. The first is ecological fallacy occurred in the course of interpreting the ecologic level of exposure-disease associations into individual level. The second is exposure isclassification which leads to serious bias. Nevertheless there is few methodologic study dealing joint effects of the two problems in ecologic study. This study was conducted to suggest an ecologic model not having an ecologic fallacy due to model linkage failure and a methodology for correcting the misclassification bias due to exposure-confounder misclassification. Finally, we suggest a criteria for the ecologic model selection. Main results are as follows: 1. A linear ecologic regression model has a serious ecological fallacy due to model linkage failure and the misclassification bias due to the exposure-confounder misclassification. 2. An interaction ecologic regression model has no ecological fallacy due to model linkage failure, but it is affected seriously by the exposure misclassification. However misclassification bias could be removed mathematically if the information related to the misclassification was known. 3. A log-linear ecologic regression model has an ecological fallacy due to model linkage failure. It is seriously biased as the individual risk ratio are increased, but relatively less affected by the exposure misclassification than interaction ecologic regression model. 4. One of the two ecologic regression model-interaction ecologic regression model and log-linear ecologic regression model- would be selected according to the information of individual risk ratio and exposure misclassification. But using a linear ecologic regression model should be avoided in any circumstance. The above results are only valid in case that there is no other source of ecological fallacy except model linkage failure. Also exposure and confounder are independent each other, measured binary, and having nondifferential misclassification. Since the above assumptions are somewhat strong in considering the real situations of ecologic studies, it is necessary to extend the scope of this study.

These radiologic studies were carried out on 265 cases of silicosis which were diagnosed clinically atindustrial Accident Hospital affiliated with Catholic Medical Collage, suring the period of 3 years from 1974 to1976. 265 cases of silicosis consisted of 96 cases (35%) of coal miner, 91 cases (34%) of coal choicer and 82cases (31%) of others. The average age was 42.2 years and average working period was 9.2years. Qualitative andquantitative features in the analysis of roentgen findings were based on UICC/Cincinnati and KLO classification.The qualitative features showed 26% of "p" opacity, 46% of "q" opacity 4% of "r" opacity as rounded profusion and5% of "s" opacity, 11% of "t" opacity, 2% of "u" opacity as irregular profusion of small opacities.Large opacitiesshowed 3% of group A, 2% of group B and 1% of group C. Quantitative features revealed 25% of Type 1, 54% of Type2, 16% of Type 3 and 5% of Type 4. The qualitative and quantitative features showed significant differences as ageand working period increased with age and working period. Major complications were pulmonary emphysema,tuberculosis and pleural abnormalities.

The purpose of this study was to identify the effects of cancer prevention and early detection education on cancer-related knowledge, attitudes, and preventive health behavior of middle-aged women in Korea. The research design was a nonequivalent control group pretest-posttest design. The subjects of this study were 38 middle-aged women from a church in Taegu. An Experimental group of 19 and a control group of 19 women were studied. The study was conducted from September 21, 2000 to October 27, 2000. The cancer prevention and early detection education had been provided to the experimental group for 2 weeks. The contents of the education program for the third most prevalent cancer of Korean women were: 'the risk factors of cancer', 'the early symptoms of cancer', 'the diagnostic test for cancer detection', and 'the cancer prevention methods'. The instruments used for this study were modified, cancer-related knowledge, and attitude, preventive health behavior tools of Suh et al.(1998). Data were analyzed using descriptive statistics, X2-test, t-test, ANCOVA with SPSS WIN 9.0/PC. The results were as follows: 1) Hypothesis 1 that the women who get cancer prevention and early detection education will have higher scores of the cancer-related knowledge than the women do not get cancer prevention and early detection education was accepted(F=4.732, p=.037). 2) Hypothesis 2 that the women who get cancer prevention and early detection education will have higher scores of cancer-related attitudes than the women do not get cancer prevention and early detection education was rejected(F=.118, p=.733). 3) Hypothesis 3 that the women who get cancer prevention and early detection education will have higher scores of cancer-related preventive health behavior than the women who do not get cancer prevention and early detection education was rejected(F=2.250, p=.143). On the basis of the above findings, the following recommendations are suggested: 1)It is necessary to identify the variables affected on cancer-related knowledge, attitudes and preventive health behavior. 2) It is necessary to develop a well organized cancer prevention and early detection education program to change cancer-related attitude and preventive health behavior.
