This study was made to suggest the nursing strategies for promoting the behaviors about bone mass health behaviors in order to prevent middle aged women's osteoporosis. This study was a descriptive-correlational design that also concerned to the types which improve bone mass promoting behaviors by inspecting patterns of health locus of control method out of recognizable variables of health improving models influencing on these bone mass promoting behaviors. For these purpose, data were collected by self reported questionnaire in middle school, from 158 women living in Seoul. The measuring tools used in this study about bone mass promoting behaviors and multidimensional health locus of control, were developed by author on the basis of literature review and analyzed by SPSS-PC window, into pearson's correlation, ANOVA, multiple regression, cluster analysis. Data was analyzed as follows. 1. 6 Multidimensional health locus of control scale clusters were existed. : a)cluster I (pure internal), b)cluster II(pure chance), c) cluster III(Believer in control), d), cluster IV(Type VI), e)cluster V(yea sayer), f) cluster VI(nay sayer). There were no findings of the powerful others external cluster and double external cluster. 2. The higher the value of internal health locus of control was, the better the bone mass promoting behaviors were(r=.2891, $p=.00^{**}$). The higher the value of chance external health locus of control was, the worse the bone mass promoting behaviors were(r=-.1367, $p=.00^{**}$). 3. On the basis of these relationships, 6 clusters were significantly different in the bone mass promoting behaviors(F=2.27, $p=.05^*$). The value of bone mass promoting behaviors was ranked the order of type VI>believer in control>pure internal>yea sayer>nay sayer>pure chance external highly. 4. Bone mass promoting behaviors were not significantly different as to age. Suggestion. Based on the results from the study, I would like to make some suggestions as follows. 1) To delay the loss of bone mass in middle aged women, the study on the cluster of the multidimensional health locus of control should be conducted repeatedly. 2) The tool of multidimensional health locus of control should be developed through a qualitative method adjusted on Korean' health culture.

The study objects were to analyze long-term and seasonal variations of nutrients (N, P), suspended solids, N:P ratios, algal chlorophyll, and trophic state along with general water quality parameters in four sampling sites including two intake tower sites supplying drinking water in Daechung Reservoir. For the analysis, we used water quality long-term data sampled during 1998~2007 by the Ministry of Environment, Korea. Interannual and seasonal trends in inflow and discharge near the intake tower facilities over the ten years were directly influenced by rainfall pattern. The distinct difference between wet year (2003) and dry year (2001) produced marked differences in water temperature, pH, dissolved oxygen, organic matter contents, nutrients, and these variables influenced algal biomass and trophic state. Values of TP varied depending on the year and locations sampled, but monthly mean TP always peaked during July~August when river inflow and precipitation were maxima. In contrast, TN varied little compared to TP, indicating lower influence by seasonal flow compared to phosphorus. The number of E. coli were highest in Site 2 (Chudong intake tower) and varied largely, whereas at other sites, the numbers were low and low variations. Contents of chlorophyll-${\alpha}$ (CHL), as an estimation of primary productivity, varied largely depending on the year and season. The maximum of CHL occurred at Muneu intake tower (S4) during 2006 when the precipitation and inflow were lowest. In contrast, another CHL peak was observed in Site 2 (Chudong intake tower) in 2006 when one of the largest typoons (Ewinia) occurred and river runoff were maximum. So the CHL maxima were associated with both wet year (high flow, high nutrient supply) and dry year (low flow, nutrient supply by littoral zone). Such conditions influenced trophic states, based on Trophic State Index of nutrients and CHL. Based on all analyses, we can provide some clues for management and protection strategies of two intake tower sites.

The study was intended to investigate the degree of satisfaction and experiences of maternity nursing practice and to examine the relationships between satisfaction and experiences. Data were collected from a college located in Inchon from April 2, 2001 to October 30, 2001. A general characteristics questionnaires, questionnaire for clinical practice satisfaction and maternity nursing clinical checklist were used to measure the satisfaction and experiences of maternity nursing practice. The subject were supposed to record their clinical experience in maternity clinical practice checklist. 153 questionnaires for satisfaction of clinical practice and 178 maternity nursing clinical practice checklists used for analysis. The data were analyzed by SPSS-PC+ program. The results of this study were as follows ; 1) The mean score of satisfaction of clinical practice was 3.34(a perfect score 5) and among the 4 categorial components from the questionnaire of satisfaction the score of 'clinical practice teaching' was high(3.85) and 'clinical practice environment(2.91)' and 'clinical practice contents(2.90)' was relatively low. 2) There was significant value between place of clinical practice and clinical practice satisfaction among 7 clinical practice hospital and the most high score of clinical practice satisfaction is 3.70 and the low score is 2.91(F=7.706, p<.001). The score of delivery room was significantly higher than the OBGY room and there was significant value among the place of clinical practice(DR : F= 6.441, p<.001, OBGY room : F=7.908, p<.001). 3) In delivery room, the frequency of observation are 2.61 day, the frequency of practice are 1.33 day and in OBGY room the frequency of observation are 1.73 day, the frequency of practice are 1.31 day for 2 week of maternity clinical practice and the most frequent practice of maternity nursing care was checking vital sign. 4) There were significant relationships between the ranking score of clinical satisfaction and clinical experiences in maternity nursing practice. Based on the results, it is suggested that the satisfaction of clinical practice was related to environment of clinical practice and it is necessary to improve environment of clinical practice and make a strategies to enhance the quality of maternity clinical experience.

Almost all of the water from agricultural dams located to the upper of the Yeongsan river is supplied as irrigation water for farmland and thus is not discharged to the main stream of the river. Also, most of the irrigation water does not return to the river after use, adding to the lack of flow in the main stream. As a result, the water quality and aquatic health of the river have become the poorest among the four major rivers in Korea. Therefore, in this study, several strategies for water quality improvement of the river were developed considering pollution reduction and flow rate increase, and their effect analysis was performed using a water quality model. The results of this study showed that the target water quality of the Yeongsan river could be achieved if flow increase strategies (FISs) are intensively pursued in parallel with pollution reduction. The reason is because the water quality of the river has been steadily improved through pollution reduction but this method is now nearing the limit. In addition, rainfall-related FISs such as dam construction and water distribution adjustment may be less effective or lost if a megadrought continues due to climate change and then rainfall does not occur for a long time. Therefore, in the future, if the application conditions for the FISs are similar, the seawater desalination facility, which is independent of rainfall, should be considered as the priority installation target among the FISs. The reason is that seawater desalination facilities can replace the water supply function of dams, which are difficult to newly build in Korea, and can be useful as a climate change adaptation facility by preventing water-related disasters in the event of a long-term megadrought.

This study was a survey study to provide the base data necessary to prepare efficient management plans for the mothers with disabled children by type, comparing degrees of disability acceptance, stress, coping method and wellness between mothers with physical functional disordered children and developmental disordered children. The study subjects were a mother who raises disordered children. Data collection was conducted from October 2018 to April 2019, and differences between the two groups were analyzed as t-test, ANOVA, and Pearson correlation. In results, Studies have shown that there are differences between the two groups as mothers with physical functional disordered children and mothers with developmental disordered children as degrees of disability acceptance, stress, treatment and wellness. Disability acceptance and coping method of mothers with physical functional disordered children (r=0.23, p=.033), disability acceptance and Wellness (r=0.51, p<.001) have shown positive correlations and disability acceptance and stress (r=-0.72, p<.001) have shown negative correlations. Disability acceptance and wellness (r=0.40, p<.001) of the mother with a developmental disordered child have shown a significant positive correlation, and disability acceptance and stress (r=-0.71, p<.001) have shown a significant negative correlations. The higher the degree of disability acceptance, the lower the stress level and the higher the coping method and wellness mothers with physical functional disordered children had. The higher disability acceptance, the lower stress degrees and the higher wellness degrees mothers with developmental disordered children had. In order to improve disability acceptance by mothers with physical functional disordered children, it was necessary to improve both coping methods and wellness with stress reducing strategy, while the mother with developmental disordered children were needed strategies to reduce stress and improve wellness.

Purpose: Confronting the growing burden of dementia requires understanding the causes and predictors of dementia in order to develop preventive strategies. In Korea a large proportion (71%) of dementia is Alzheimer's disease, and the risk factors have not yet been elucidated. Dietary factors may be possible risk factors, however research on the relationship between Alzheimer's disease and dietary behaviors has been insufficient. The purpose of this study was to investigate the association between compliance with the "Dietary Guidelines for Elderly (The Ministry of Health and Welfare, 2011)" and Alzheimer's disease among Korean elderly. Methods: Elderly persons who visited a University hospital or a dementia center of Seoul and agreed to participate in the examinations were selected. Among 277 subjects, 89 Alzheimer patients were selected with diagnosis and 118 subjects were assigned to the control group. Diagnosis of Alzheimer's disease was based on Alzheimer's disease criteria of Diagnostic and Statistical manual of Mental Disorders, 4th edition (DSM-IV) and criteria of National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and related Disorders Association (NINCDS-ADRDA). Information on the general characteristics, health related behaviors and compliance with the dietary guidelines for Korean elderly was collected by face to face interview using a structured questionnaire. Anthropometric variables were measured during the survey. Results: Total compliance score of dietary guidelines was significantly lower in the Alzheimer's disease group than in the control group (p = 0.0001). The odds ratio of Alzheimer's disease was significantly decreased in the group with the highest dietary guideline compliance score (OR = 0.47, 95 % CI = 0.18~1.09) compared to the group with the lowest compliance score. Conclusion: The results indicate that increasing compliance with the dietary guidelines could be an effective strategy to decrease the risk of Alzheimer's disease among Korean elderly.

The purpose of this study was to evaluate the needs and effects of convergence-based simulation practice for obstetrical nursing. The study participants were 47 junior nursing students of a university in Chungnam province. Data were collected by a self-administered questionnaire from February 13 to 25, 2012. Convergence-based simulation practice for obstetrical nursing was applied 8 hours in a day for 2 days and consisted of four sessions. Self-efficacy in obstetrical nursing (t=-14.74, p<.001) and nursing skills related to obstetrical nursing (t=-17.51, p<.001) showed significant increase in the posttest and practice satisfaction was higher than practice stress. The needs of simulation practice was 7.96 out of 10 point and higher as practice satisfaction was higher. The needs of simulation practice before clinical practice was higher than simulation practice after clinical practice. These results indicate that simulation practice for obstetrical nursing can be used as the alternative for clinical practice. In addition to simulation practice should be done before clinical practice and strategies to increase the nursing student's cognition for the need of simulation practice are also needed.

The purpose of this study is to find out methods to control, regulate and prevent sexual violence and provide guidelines for sex education in middle school. This study was conducted to examine factors in relation to sexuality, attitudes toward women, experience of sexual contact, frequencies and kinds of pornography with which they had contact, and sex education. For the data collection, a survey was conducted from September 25 to October 1, 1997 by using prepared questionnaires. Questionnaires were given to 503 students from three different kinds of middle schools in Seoul, Boys, Girls, and Coeducation schools. The data analyses used a PC-SAS. Each item was examined by frequencies and percentage. To compare Boys with Girls, I applied a T-test. In addition, with the kinds of school type, I applied anANOVA, ${\chi}^2$. Moreover, For investigating and analyzing each category, I categorized knowledge and attitude of sexuality, with precautionary measures of sexual violence. After that I applied T-test, ANOVA, and a Pearson's correlation for each category. The instruments of this study consisted of 9 domains. (1) General characteristics of the respondents (2) 9 questions about the interaction between he/she and his/her parent. (3) 12 questions, concerning A Scale for Attitudes of Adolescents Toward women(AWSA). (4) 26 questions related to sexual knowledge. (5) 25 questions about sexual attitude (6) strategies for prevention of sexual violence-33 questions (7) 5 questions related to sexual behavior (8) the experience of contact with pronography. (9) the experience of sex-education. The major results were summarized as follows; 1. Like many researches, This study shows that the girls are more eqalitarian than boys. The girls mean ($40.90{\pm}3.67$) is significantly higher than boys ($34.72{\pm}3.77$). Most Koreans have believed that there are many differences between men's roles and women's ones, because of confucianism which had been implied in most thought and ideas since the Lee dynasty. Therefore, the result is not surprising at all. 2. Most students answered correctly the questions of sexual knowledge. The girl's score was higher ($Mean{\pm}SD$ : $48.88{\pm}2.39$) than the boys' ($Mean{\pm}SD$ : $46.95{\pm}3.90$)(p 0.001). Nevertheless, the hypothesis that sexual knowledge influences sexual attitude and its behavior was rejected. 3. When twenty-five questions were asked about sexual attitude, the girl students investigated were found to have a more propre sexual attitude than that of the boys. A significant difference was found between boys and girls(p=0.001). The result shows that a person who has more experience in viewing pornography and who smokes will have a more distorted view of sexuality. 4. There are many students who have experienced of sexual contact. They need to take a sex education program about contraception and prevention of sexually transmitted diseases. Systematic and concrete sex education is one way to lead them to proper sexual behavior. 5. Most respondents rejected stereotyped attitudes towards women. Boys, however, were more likely to accept stereotypes of Women. The girl's mean($Mean{\pm}SD$ : $40.90{\pm}3.67$) is higher than the boys($Mean{\pm}SD$ : $34.72{\pm}3.77$)(p=0.0001). 6. Many boys ignored the rules for prevention of sexual violence. A boy or a girl who has more experience of sexual contact over kiss and sex-typed neglected the rules, too(p=0.001). Today, there is increasing juvenile delinquency related to sexuality. This study provided the basic material for a preventive education system. I believe that a systematic and concrete sex education system can be helpful for adolescents and promote their responsibility as well as cultivate morality about sexuality. As a result, juvenile delinquency can be decreased. This study is basically aimed to provide information for a prevenative education system of sexual violence. Further research is recommended to evaluate programs in schools.

Purpose: This study was conducted to identify risk factors in hospitalized children, and to develop and validate a fall-risk assessment tool for hospitalized children. Methods: A retrospective chart review was performed at one university children's hospital, and an analysis was done of the characteristics of all patients who fell during a 44-month period (n=48). These patients were compared with another 149 hospitalized children who did not fall. Results: Significant predictors of falls as identified in a multivariate logistic regression analyses were age of less than 3 years old, neurological diagnosis including epilepsy, children's dependency of ADL, physical developmental delay, multiple usage of fall-risk-increasing drugs. The respective odds ratios ranged from 2.4 to 7.1 with 95% confidence interval (p<0.05). Accordingly, defining patients with either 5 risk factors as fall-prone hospitalized children provided a sensitivity of 93.6% and specificity of 16.2%. Conclusion: The results show that this tool has an acceptable level of sensitivity to assess the risk factors of fall in hospitalized children even though the specificity was low, suggesting that this tool may enable nurses to predict the risk level of childhood falls, and develop preventive strategies against pediatric falls in children's units.

To investigate the change of perception after weight management education in elementary, middle and high school students, a survey was conducted. Same questionnaire was administered twice, before and after weight management education, to 426 students at 9 schools in Seoul area. The mean height, weight and body mass index were 145.5$\pm$8.0cm, 40.0$\pm$8.3kg, 18.6$\pm$3.0 for elementary school students, 160.1$\pm$5.2cm, 50.2$\pm$7.3kg, 19.5$\pm$2.4 for middle school students, and 162.2$\pm$5.0cm, 52.2$\pm$6.4kg, 19.8$\pm$2.3 for high school students, respectively. Before education, their preferred weight and perceived healthy weight was 35.4kg and 37.0kg among elementary school students, 44.8kg and 46.5kg among middle school students, and 47.3kg and 48.9kg among high school students, respectively. Differences between their present body weight and their preferred weight and/or perceived healthy weight appeared to be 4.5kg and 2.9kg in elementary school students, 5.6kg and 4.0kg in middle school students, and 5.1kg and 3.3kg in high school students, respectively. After administering education, the differences decreased to 2.5kg and -0.2kg in elementary school students, 4.2kg and 2.7kg in middle school students, and 4.3kg and 2.0kg in high school students, respectively (p<0.01). And their perception on own body shape was investigated using 5 point scale ('too lean' to 'too fat', 1 to 5) before and after education. The mean values changed from 3.1 to 2.8 in elementary school students, from 3.3 to 3.0 in middle school students, and from 3.4 to 3.2 in high school students (p<0.01). Their satisfaction with own body weight was monitored using 5 point scale ('very satisfied' to 'very unsatisfied', 1 to 5), also. The mean values changed from 3.0 to 2.7 in elementary school students, from 3.6 to 3.2, in middle school students, and from 3.8 to 3.4 in high school students (p<0.01). In the evaluation of their nutrition knowledge about weight control using 10 item quiz, before and after education, the mean quiz score was changed from 6.3 to 7.0 in elementary school students, from 7.0 to 7.9 in middle school students, and from 7.5 to 8.1 in high school students (p<0.01). In summary, nutrition education on weight management improved the subject's perception on perceived healthy weight and own body shape, and satisfaction with present body weight. This result suggests that nutrition education program should incorporate strategies to change incorrect beliefs and knowledge regarding weight control. Onto this, weight control education for students should start from their early age, be repeated periodically and consistently, and focus on the harmful effects of excessive weight loss and information on the practical and scientific ways of weight management.
