BACKGROUND: Previous studies have suggested that regular exercise may increase bone mineral density. However, the effects on bone mineral density are different depending on the types of exercises and recent studies on the effects of different exercises on bone mineral density are insufficient. This study was conducted to assess the effects of 2 different exercises(Judo, Taekwondo) and physical fitness(back muscle strength, grip strength, broad jump, vertical jump, flexibility, sit ups) on regional BMD. METHODS: Subjects were healthy adults female volunteers aged 19 to 22 years and consisted of eight Judo athletes, twelve Taekwondo athletes, and eight nonathletic controls. We measured their bone mineral density of lumbar spine, femoral neck, femoral greater trochanter, Wards triangle, femoral shaft and distal radius using dual energy X ray absorptiometry and assessed their physical fitness. We investigated the mean differences of regional bone mineral density between the groups and the relationships between physical fitness and regional bone mineral density. RESULTS: ANCOVA revealed that there were significant differences in the regional bone mineral density between the groups. The Judo athletes group had significantly higher bone density of greater trochanter, femoral shaft, distal radius, femoral neck and lumbar spine than the control group and had significantly higher bone density of greater trochanter, femoral shaft and distal radius.than the Taekwondo atheletes group. There were no significant differences of bone density in all the regions between the Taekwondo atheletes and the control groups. Partial correlation coefficients between the back muscle strength and the bone density of Wards triangle, greater trochanter, distal radius, femoral neck, femoral shaft, and lumbar were 0.581, 0.570, 0.526, 0.502, 0.424, and 0.418, Respectively (P<0.05). Correlation coefficients between the broad jump and the bone density of femoral neck, greater trochanter, and femoral shaft were 0.577, 0.539, and 0.457, respectively(P<0.05). Correlations of the grip strength, flexibility, sit ups and vertical jump with bone density of all regions were not high(r< or=0.5). CONCLUSIONS: Different types of exercises showed different effects of bone density. The back muscle strength among the physical fitness factors was considered to be the most important predictor of bone density. In the future, further studies are necessary for the effects of other exercises on bone density.

Breast self-examination is the most effective and easiest way for women to increase the responsible consciousness about their health. The purpose of this study was to test the variables impacted to promote breast self-examination practice. The research design used in this study was a nonequivalent control group of a non-synchronized design. The sample that was assembled consisted of 124 women. A purposive sample consisted of 124 omen. Each subject was given to assessed on the following the demographic data relate to the breast self-examination, knowledge of self-examination, accuracy, in performing self-examination, self-efficacy about breast cancer and breast self-examination, and the number of subjects who found a mass. The result of this study may be summarized as follows : 1. To examine the theoretical model fit to the data, chi square test statistics and goodness of fit index were identified(x2=2.30, df=2, GFI=0.99, AGFI=0.94 RMSR=0.02, NFI=0.99, NNFI=0.99, Critical Number=439). 2. The direct effects of education of breast self- examination were knowledge, self-efficacy, accuracy, number finding a mass. But the indirect effect of education in breast self-examination was frequency of breast self-examination. 3. Knowledge, as direct paths to the breast self-examination practices, was removed in the theoretical model. The parsimonious best fit model included self-efficacy, accuracy, the number finding mass, frequency of breast self-examination practices. 4. The final model produced a chi-square=5.58(p=0.35) with df=5, and GFI=0.99 AGFI=0.94, NFI=0.03, NFI=0.99, NNFI=0.99, CN=339 indicating very a good fit. Based on the result of this study, education of breast self-examination is very effective for increasing the competency of the breast self-examination through the knowledge and self-efficacy. Resources to promote self-examination may be helpful to increase the frequency of self-examination because self-efficacy is a direct effort on it. These findings suggest the need t develop nursing strategy to promote the self- efficacy of breast self-examination.

The purposes of this study were to understand the sex role identity and the meaning in life(MIL) of matriarchs and analyze their relationships to offer basic data for effective nursing strategies for improving MIL. The data for this study was collected from the 10th of August to the 30th of November, 2000. The subjects were women registered in an occupational training program for unemployed matriarchs which is held in the Working Women's Center in Busan. The measurement tools of this study were MIL(unpublished)developed by researchers and sex role inventory designed by Kim Deuk Ran(1992). The results of this study were as follows: 1.Sex role identities of matriarchs were feminity 13.7%, masculinity 13.4%, androgyny 37.8% and undifferentiated 35.1%. 2. The mean MIL for matriarchs was 173.46+/-16.09. 3. The levels of MIL were 57.2% of the subjects felt a loss of meaning in life, i. e. existential vacuum, 42.8% were in pursuit of meaning but had not discovered it completely and 6.0% felt they had established meaning in life. 4.There were significant differences in MIL levels, concurrent to 4 types of sex role identities(F=11.93, P=.000). And according to Scheffe's post test, between feminity and masculinity, feminity and androgyny, masculinity and the undifferentiated, androgyny and the undifferentiated, there were significant differences. From the results of this study, most matriarchs felt loss of meaning in life, i. e. existential vacuum, and the group with masculine sex role identity had the highest level of MIL. In conclusion, the factors related to masculine sex role identity are necessary to develop nursing strategies for improving levels of MIL.

During the last decade, genomic cohort study has been developed in many countries by linking health data and genetic data in stored samples. Genomic cohort study is expected to find key genetic components that contribute to common diseases, thereby promising great advance in genome medicine. While many countries endeavor to build biobank systems, biobank-based genome research has raised important ethical concerns including genetic privacy, confidentiality, discrimination, and informed consent. Informed consent for biobank poses an important question: whether true informed consent is possible in populationbased genomic cohort research where the nature of future studies is unforeseeable when consent is obtained. Due to the sensitive character of genetic information, protecting privacy and keeping confidentiality become important topics. To minimize ethical problems and achieve scientific goals to its maximum degree, each country strives to build population-based genomic cohort research project, by organizing public consultation, trying public and expert consensus in research, and providing safeguards to protect privacy and confidentiality.

Observational studies constitute an important part of epidemiologic research. Researchers need to recognize that some of the observational studies may result in serious damage to the participants, and it is very important to understand that which aspect of such studies may pose a risk to the participant. The key element of an observational study that may raise an important ethical issue is specific information itself. Researchers need to make sure who has the right to make decision on the information, and by what pathways the information flows. Informed consent is an essential component involved in handling the information associated with participants' interest. Institutional review board (IRB) should oversee the study design and procedures to ensure the study procedures respect the rights of the participants and communities they belong to and protect them from any harm. Modern technologies add new dimensions to observational studies because of genetic information and large scale database systems that are linked with the study. Data security need to be assured by various procedures and legal protections. As the value of information becomes greater in the modern society, the importance of bioethics and personal information protection also becomes greater in the observational studies.

PURPOSE: The purpose of this study was to develop elderly meaning in life scale with high validity and reliability. METHOD: The process of development of this scale were as follows. A conceptual framework composed of 4 phases of meaning in life of elderly was identified based on the literature review and interviews with elderlies and discussion with experts in meaning in life. Total 62 items, 4-points scale were developed. Through reliability testing, factor analysis, 40 preliminary items were selected. By means of internal consistency of 40 items, 2 items whose inner-items correlation coefficient was below .30 were deleted. Through factor analysis 1 item whose factor loading was below .30 was deleted. Finally 37 items were remained. To verify 37 items, factor analysis, reliability testing, LISEREL were done. Data were collected from 320 elderly subjects in Busan-KyungNam and Jeonla Province from May to June in 2002.. SPSS WIN. 10.0 Program was used. RESULT: The result of factor analysis of 37 items, 8 factors were extracted. These factors were labeled as 'self- awareness and self-acceptance', 'contentedness with life', 'purpose in life', 'love in family', 'role awareness', 'futuristic aspiration', 'commitment', and 'experience of love'. These factors included 4 phases of the meaning in life. Cronbach's Alpha of 37 items was .908 and correlation coefficient of PIL was .75. CONCLUSION: The researchers recommend the follows : The explorative study on the variables related to meaning in life are needed for criterion validity of this scale. The studies on meaning in life of different age groups, subjects are needed for reverification.

This study was designed to develop a program for unemployed matriarchs and show if the program affected their view on the meaning in life. The subjects were women registered in an occupational training program for unemployed matriarchs, which is being practiced in the 'Working Women Center' located in Busan. The researchers selected 44 persons from the group who agreed to our program. This study was done from the 10th of March, 1999 to the 9th of October. The researchers used the measurement tools, The Purpose in Life, Self-esteem, Hope and Meaning in Life which was composed of 63 items developed by them. Their Cronbach's alpha were .88, .79, .76 and .95. The researchers analyzed the data with frequency, percentage, Mean, S.D, Wilcoxon signed ranks test which were deduced from SPSS 10.0 WIN program. The results of this study were as follows: 1) The program is composed of 'becoming intimate', 'open-minded', 'exploration on self', 'relax of repressed emotion', 'self- acceptance', 'establishing the life-goal', 'enrichment of human relationship' and closing. It took 20 hours for this program to come into practice. 2) According to the analysis of the general traits of all subjects, average age was 39.36. High school graduates were 86%, college graduates were 14% and divorce were 57%, bereavement were 18%, and the rest were 25%. 3) The result of 1st progam showed self-esteem during the program was high. 4) The result of 2nd progam showed self-esteem during the program was high. 5) The result of 3rd progam showed the sum scores of meaning in life, creative meaning, and attitudinal meaning during the program was high. 6) The result of 4th progam showed the sum scores of meaning in life and creative meaning during the program was high. On the viewpoint of above results, we convinced that 'a program for unemployed matriarch is effective to establish a stronger meaning in life. Therefore, it is demanded that support for unemployed matriarchs should not only be economic help such as technical training and help of living expenses, but also psychological, professional and systematic support.
