This descriptive correlation study attempted to analyze the relationship between school health practice competency and satisfaction of school health practice in nursing college students. The participants in this study included 191 nursing college students from three junior colleges. The data were collected using a self-reported questionnaires developed or revised by the authors from 22 June to 7 July, 2002. The data were analyzed with the SPSS program using descriptive statistics, t-test, ANOVA, pearson correlation coefficient. The results of this study were as follows: 1. The mean score of school health practice competency was 3.59. The mean score of health education, health management, nursing process, environmental management were 3.81, 3.73, 3.47 and 3.36 respectively. 2. The mean score of school health practice satisfaction was 3.34. The mean score of instruction, practice environment, contents, practice hours and evaluation were 3.66, 3.37, 3.26, 3.21 and 3.21 respectively. 3. Type of school was only significant factor in general characteristics related to satisfaction of school health practice. 4. Correlation between school health practice competency and satisfaction of school health practice showed that the positive correlation between satisfaction and competency (r=0.247, p=0.00l). nursing process(r=0.356, p=0.000), environmental management (r=0.153, p=0.035). In conclusion, this study found that satisfaction of school health practice was significantly related to school health practice competency in nursing college students. Therefore further study is needed to make a strategies to enhance the quality of school health practice competency in nursing college students.

Purpose: The purpose of this study was to exam me the effects of aquatic exercise on pain, fatigue, body composition, physical fitness and psychological variables in women with arthritis. Method: With a quasi-experimental design, 37 women who had arthritis were assigned into an experimental group (n=19) or a control group (n=18). Aquatic exercise consisted of one hour of exercise in water, two days per week, for six weeks and a self-help process. Measures included physiologic and psychological variables before and after the exercise. Data was analyzed with the SPSS WIN using descriptive statistics, t-test, and ANCOVA. Result: The mean age of the subjects was 59 years in the experimental group and 52 years in the control group. Pretest scores in outcome variables were similar in both groups except BMI and body fat(%). After controlling for age, shoulder flexibility scores in the experimental group improved more than the control group (Rt: F=10.58, p=.003; Lt: F=5.91, p= .02; Waist: F=4.95, p= .03). Depression scores in the experimental group decreased (F=12.96, p= .001), and self efficacy and quality of life improved more than the others (F=5.07, p= .03; F=6.9l, p= .01). Conclusion: Aquatic exercise can improve waist flexibility and shows consistent findings of improved shoulder flexibility and psychological function in women with arthritis.

Purpose: The purpose of this study was to identify the levels of physical activity and its relationships with depression, health-related quality of life (QoL), sleep disturbance, and physiological indicators in hemodialysis patients. Methods: The participants in this study were 139 patients undergoing hemodialysis in the hospitals in Busan and Yangsan-si. Data were collected using hematologic tests and questionnaires that contained items about individual characteristics, International Physical Activity Questionnaires (IPAQ), Center For Epidemiological Studies Depression Scale (CES-D), a 12-item Short-Form Health Survey (SF-12), and Pittsburgh Sleep Quality Index (PSQI). Data were analyzed using descriptive statistics, one way ANOVA, and correlation. Results: Mean age of the participants was $59.91{\pm}12.63$ and mean physical activity levels were $1,660.35{\pm}1,654.17$. Patients who performed higher physical activities during their daily activities reported lower levels of depression (F=4.16, p=.018) and higher levels of QOL (PCS: F=5.00, p=.008, MCS: F=8.66, p<.001) than those of the others who did not perform physical activities. Conclusion: This study showed that the levels of physical activity among hemodialysis patients was significantly associated with their depression and QOL. Developing strategies for enhancing physical activity is warranted to improve depression and QOL among hemodialysis patients.

Background: The generalized gamma distribution statistics constitute an extensive family that contains nearly all of the most commonly used distributions including the exponential, Weibull and log normal. A saturated version of the model allows covariates having effects through all the parameters of survival time distribution. Accelerated failure-time models assume that only one parameter of the distribution depends on the covariates. Methods: We fitted both the conventional GG model and the saturated form for each of its members including the Weibull and lognormal distribution; and compared them using likelihood ratios. To compare the selected parameter distribution with log logistic distribution which is a famous distribution in survival analysis that is not included in generalized gamma family, we used the Akaike information criterion (AIC; r=l(b)-2p). All models were fitted using data for 369 women age 50 years or more, diagnosed with stage IV breast cancer in BC during 1990-1999 and followed to 2010. Results: In both conventional and saturated parametric models, the lognormal was the best candidate among the GG family members; also, the lognormal fitted better than log-logistic distribution. By the conventional GG model, the variables "surgery", "radiotherapy", "hormone therapy", "erposneg" and interaction between "hormone therapy" and "erposneg" are significant. In the AFT model, we estimated the relative time for these variables. By the saturated GG model, similar significant variables are selected. Estimating the relative times in different percentiles of extended model illustrate the pattern in which the relative survival time change during the time. Conclusions: The advantage of using the generalized gamma distribution is that it facilitates estimating a model with improved fit over the standard Weibull or lognormal distributions. Alternatively, the generalized F family of distributions might be considered, of which the generalized gamma distribution is a member and also includes the commonly used log-logistic distribution.

Purpose: This study was to compare quality of life, sexual function, and depression between a group with sexually active women and the other with sexually inactive women who undertaken mastectomy. Methods: Participants were 106 breast cancer patients who had spouse and participated in self-help group in Gwangju, Korea. The questionnaires were consisted of Quality of Life Index-Cancer Version (Q.L.I.-C), self-rating depression scale, and Female Sexual Function Index (FSFI). Data were analyzed using the SPSS Win 14.0 K+ for descriptive statistics, t-test, ANCOVA, and MANOVA. Results: There were no homogeneity at age, job, educational years between sexually active vs. inactive groups. In sexually active group, mean age was 46.1, having job 34.5%, bachelor's degree 38.2%, and pre-menopause 79.2%; for the inactive group 49.6, 10.4%, 12.5%, and 52.7% seperately. There were significant differences in quality of life, sexual function, and depression between two groups when four covariates were controlled. The quality of life and sexual function in sexually active group were significantly higher than inactive group(p<0.001). The depression in sexually active group was significantly lower than inactive group(p<0.001). Conclusion: This study indicates that nurses are needed to counsel and intervene psychosexual approach especially sexually inactive women with breast cancer during the recovery period.

Objective : Use of quantitative computed tomography (CT) to evaluate bone mineral density was suggested in the 1970s. Despite its reliability and accuracy, technical shortcomings restricted its usage, and dual-energy X-ray absorptiometry (DXA) became the gold standard evaluation method. Advances in CT technology have reduced its previous limitations, and CT evaluation of bone quality may now be applicable in clinical practice. The aim of this study was to determine if the Hounsfield unit (HU) values obtained from CT correlate with patient age and bone mineral density. Methods : A total of 128 female patients who underwent lumbar CT for back pain were enrolled in the study. Their mean age was 66.4 years. Among them, 70 patients also underwent DXA. The patients were stratified by decade of life, forming five age groups. Lumbar vertebrae L1-4 were analyzed. The HU value of each vertebra was determined by averaging three measurements of the vertebra's trabecular portion, as shown in consecutive axial CT images. The HU values were compared between age groups, and correlations of HU value with bone mineral density and T-scores were determined. Results : The HU values consistently decreased with increasing age with significant differences between age groups (p<0.001). There were significant positive correlations (p<0.001) of HU value with bone mineral density and T-score. Conclusion : The trabecular area HU value consistently decreases with age. Based on the strong positive correlation between HU value and bone mineral density, CT-based HU values might be useful in detecting bone mineral diseases, such as osteoporosis.

Purpose: The purpose of this study was to identify over time the changes of cancer symptom, depression and quality of life (QOL) among people who had stomach or colorectal cancer. Methods: Of the 74 participants recruited, 67 participated in the study. Participants were asked to complete three instruments at three different time. The instruments were the M. D. Anderson Symptom Inventory-Gastrointestinal Cancer Module, Hospital Anxiety Depression Scale, and the Functional Assessment of Cancer Therapy-General. The questionnaires were administered before chemotherapy, toward the end of chemotherapy, and six months after the completion of adjuvant therapy. Data were analyzed using descriptive statistics and repeated measure ANOVA. Results: At the immediately after chemotherapy point, the most frequent symptom was lack of appetite, followed by fatigue and problem with remembering things. The mean score for depression was 8.27 with a prevalence of 31.3%. The mean score for quality of life was 61.88 out of 135. Repeated measures ANOVA showed a significant increase in cancer symptom (F=23.22, p<.001) and depression (F=35.29, p<.001) after chemotherapy. However, improvement was observed 6 months after the completion of chemotherapy. QOL (F=33.73, p<.001) also showed similar patterns as observed with cancer symptom and depression. Cancer symptom was the strongest predictor of QoL at pre-chemotherapy point. but depression was the strongest predictor at immediately after chemotherapy point. Conclusion: Chemotherapy is highly associated with cancer symptom, depression and QOL in patients with cancer. The nursing intervention is needed to relieve depression as well as cancer symptoms to improve QOL in patients undergoing chemotherapy from baseline to follow-up.

The changes of cooked rice stored in an electric rice cooker at different temperature were investigated using sensory and mechanical methodology. The desirability of cooked rice was deteriorated during storage, particulary cooked rice stored at $80^{\circ}C$ had the lowest desirability. As the storage time increased, glossiness, clumpiness, adhesiveness, moistness and sweet flavor of cooked rice decreased but browning and off-flavor increased. The higher storage temperature resulted in the lower in glossiness, firmness, cohesiveness, moistness, sweet flavor and in the more browning, adhesiveness and off-flavor. L and b values measured by Hunter Color Difference Meter were highly correlated with the sensory glossiness and color.

In order to investigate the complaint rates of subjective fatigue symptoms and study the relationship between them and body type, health awareness in middle school students, we carried out a survey of 1,209 students (654 boy students and 555 girl students) at a middle school in Taejon City by a self-recorded questionnaire. The survey was conducted in June, 1997. The results obtained were as follows: 1. Among complaints of fatigue, "feel like lying down" was the highest, followed by "feel anxious about things", "feel drowsy", "yawning a lot", "eye strain" and "whole body feels tired" in descending order. 2. In the average weighted score of fatigue complaint, dullness and sleepiness (I) was the highest, followed by a difficulty in concentration (II) and bodily projection of fatigue (III) in descending order. Fatigue seems to create mental stress rather than physical burdens. 3. In the classification of body type based on the $R\ddot{o}hrer$ index, the obesity type (145 and above) was 11.0%, standard type (110~144) was 64.7% and leptosomic type (l09 and below) was 24.3%. Comparison between both sexes revealed that the rate of obesity and leptosomic types were significantly higher in boy students than in girl students. 4. In terms body type awareness, the statistics are the following: those who consider themselves to be standard type, 44.3%, slightly obese 24.5%, leptosomic, 23.5% and obese 7.8%. However, the level of obesity awareness was significantly higher in girl students than in boy students. 5. As for health awareness, 36.5% considered themselves healthy, 5.4% generally healthy and 10.1% a little unhealthy, but the level of unhealthy awareness was higher in girl students than in boy students. 6. In the relationship between body type and health awareness, most students thought that they were obese in spite of their standard body type. Also, many students who were obese and leptosomic tended to consider themselves to be a little unhealthy. 7. The more the students were obese or felt unhealthy, the more the average weighted score of fatigue complaints was high.

Sets of weather variables for estimation of LWD were evaluated using CART(Classification And Regression Tree) models. Input variables were sets of hourly observations of air temperature at 0.3-m and 1.5-m height, relative humidity(RH), and wind speed that were obtained from May to September in 1997, 1998, and 1999 at 15 weather stations in iowa, Illinois, and Nebraska, USA. A model that included air temperature at 0.3-m height, RH, and wind speed showed the lowest misidentification rate for wetness. The model estimated presence or absence of wetness more accurately (85.5%) than the CART/SLD model (84.7%) proposed by Gleason et al. (1994). This slight improvement, however, was insufficient to justify the use of our model, which requires additional measurements, in preference to the CART/SLD model. This study demonstrated that the use of measurements of temperature, humidity, and wind from automated stations was sufficient to make LWD estimations of reasonable accuracy when the CART/SLD model was used. Therefore, implementation of crop disease-warning systems may be facilitated by application of the CART/SLD model that inputs readily obtainable weather observations.
