Purpose: The purpose of this study was to investigate the influences of body mass index (BMI), mindfulness and self-esteem on reported body image among university students. Methods: Data were collected through questionnaires from 266 students and were analyzed using descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficients and Stepwise multiple regression analysis with SPSS/WIN 19.0 program. Results: As defined by body mass index, the sample was divided into an underweight group was 88.7%, a normal weight group was 10.5%, and an overweight group was 0.8%. The levels of body image depended on family income, personality, and BMI. The body image was significantly correlated with BMI, mindfulness, and self-esteem. The influential factors affecting body image were self-esteem, BMI, family income and personality, which explained about 34.6% of the variance. Conclusion: The results of this study indicate that nursing intervention are needed to improve body image, and that such variables should be carefully considered in intervention for university students.

Purposes: To identify the predictors of calcium intake behavior and examine the relationships among bone mineral density, osteoporosis knowledge, osteoporosis health belief, osteoporosis self efficacy and calcium intake behavior of postmenopausal osteoporosis patients. Methods: The subjects consisted of 94 patients. The measurement tools were osteoporosis knowledge test, osteoporosis health belief scale, osteoporosis self-efficacy and calcium intake frequency questionnaire. The data were analyzed using the SPSS WIN 11.0 program. Results: The bone mineral density of the lumbar were $0.75g/cm^2$, T-score -2.67 and the femur neck were $0.67g/cm^2$, T-score -2.30. There was statistically a significant correlation between calcium intake behavior and health motivation (r=0.449, p=0.000) among the osteoporosis health belief. In hierarchial multiple regression analysis, current spouse(12.8%) and health motivation(19.9%) of the osteoporosis health belief explained the 32.7% of variance in calcium intake behavior. Conclusion: Nursing intervention should be developed for increasing the calcium intake behavior through promoting health motivation for the postmenopausal osteoporosis women having no spouse currently.

Purpose: The purpose of this study was to identify the relationship between patient characteristics and patient satisfaction. Methods: A cross-sectional questionnaire survey was conducted in an acute care hospital. The subjects were 317 patients discharged from general medical and surgical nursing care units during September, 2005. Patient satisfaction was measured using the short-form satisfaction scale of Hwang and Park(2001). Additional information about patient characteristics, including general demographics and health care utilization variables, was collected from the hospital information systems. Multiple regression analysis was performed to determine patient characteristics influencing patient satisfaction. Results: Patients were satisfied with hospital care with an average of 4.10 on a five-point Likert scale. Patient characteristics explained 13.5% of the variance of patient satisfaction. The significant factors influencing patient satisfaction were patients' age and perceived health status. There was no significant relationship between structural variables and patient satisfaction. Conclusion: This study showed that patients' characteristics were significant factors explaining patient satisfaction. Therefore, these characteristics should be adjusted in reporting patient satisfaction as an indicator for hospital-level or department-level rating.

Purpose: This study was done to explore the relationship between aggression and internet over-use, depression-anxiety, self-esteem, all of which are known to be behavior and psychological characteristics linked to "at-risk" children for aggression. Methods: Korean-Child Behavior Check List (K-CBCL), Korean-Internet Addiction Self-Test Scale, and Self-Esteem Scale by Rosenberg (1965) were used as measurement tools with a sample of 743, 5th-6th grade students from 3 elementary schools in Jecheon city. Chi-square, t-test, ANOVA, Pearson's correlation and stepwise multiple regression with SPSS/Win 13.0 version were used to analyze the collected data. Results: Aggression for the elementary school students was positively correlated with internet over-use and depression-anxiety, whereas self-esteem was negatively correlated with aggression. Stepwise multiple regression analysis showed that 68.4% of the variance for aggression was significantly accounted for by internet over-use, depression-anxiety, and self-esteem. The most significant factor influencing aggression was depression-anxiety. Conclusion: These results suggest that earlier screening and intervention programs for depression-anxiety and internet over-use for elementary student will be helpful in preventing aggression.

The purpose of this study is to identify the factors of benefits sought and rental intension based on the rental experience of clothing. To collect the data, 520 sheets of questionnaires, mostly self-administered, were used. And they were analyzed by SPSS(Ver. 10.0): frequencies, percentage, mean, factor analysis, ANOVA, and stepwise multiple regression. The results are as follows: 1. The most frequently-rented clothing items include a wedding dress and a graduation gown. The respondents were divided into 3 groups based on the rental experience: the light-experienced, the medium-experienced, and the heavy-experienced; 2. Factors of benefits sought in rental clothing include wearer compatibility, reasonability, condition compatibility, space saving, and conformity, and the total variance is 64.61%; 3. The heavy-experienced group tends to pursue wearer compatibility, reasonability, space saving, and conformity. The elder housewives with higher education who spend much on clothing belong to that group. The light-experienced includes male university students who do not spend much on clothing, and the medium-experienced includes elder employees; 4. Reasonability and clothing rental experience significantly affect rental intention, and their influence is 14.20%.

Purpose: The purpose of this study was to examine the effect of foot position and lifting an object on muscle activity and foot pressure during sit to stand(STS) in hemiparetic patients. Methods: Fourteen patients participated in this study. Surface electromyography was used to collect muscle activity and foot pressure measurement system was used to analyze foot pressure in hemiparetic side. Three different foot position was assumed(anterior, neutral, posterior) in hemiparetic side. The repeated two-way analysis of variance and multiple comparisons were conducted to determine statistical significance with a significance level of 0.05. Results: The results were as follows. 1) Lower extremity muscle activity was significantly higher(p<0.05) in biceps femoris and tibialis anterior muscle during STS without holding an object. With changing positions of the affected foot, muscle activity was significantly increased (p<0.05) in vastus medialis and lateral gastrocnemius when the foot was positioned in posterior. 2) There was no significant difference(p>0.05) in foot pressure during STS with object holding and foot positioning. Conclusion: Muscle activity showed a significant increase when the foot was positioned in posterior in comparison to the muscle activity when the foot was in neutral or anterior position.

Forecasts of monthly landings of walleye pollock, Theragra chalcogramma, in Korea were carried out by the seasonal Autoregressive Integrated Moving Average(ARlMA) model. The Box - Cox transformation on the walleye pollock catch data handles nonstationary variance. The equation of Box - Cox transformation was Y'=($Y^0.31$_ 1)/0.31. The model identification was determined by minimum AIC(Akaike Information Criteria). And the seasonal ARlMA model is presented (1- O.583B)(1- $B^1$)(l- $B^12$)$Z_t$ =(l- O.912B)(1- O.732$B^12$)et where: $Z_t$=value at month t ; $B^p$ is a backward shift operator, that is, $B^p$$Z_t$=$Z_t$-P; and et= error term at month t, which is to forecast 24 months ahead the walleye pollock landings in Korea. Monthly forecasts of the walleye pollock landings for 1993~ 1994, which were compared with the actual landings, had an absolute percentage error(APE) range of 20.2-226.1 %. Thtal observed annual landings in 1993 and 1994 were 16, 61OM/T and 1O, 748M/T respectively, while the model predicted 10, 7 48M/T and 8, 203M/T(APE 37.0% and 23.7%, respectively).

The live loads acting on structures are generally computed in terms of equivalent uniformly distributed loads for the simplicity in design process. The loads, therefore, tend to decrease with increasing influence area in both load intensity and variance. Since multi-story column loads result from accumulation of loadings acting on several different floors, its influence area becomes wider and lifetime maximum decreases. In the design codes proposing the design loads for types of structural members (i.e., slabs, beams, columns), not for tile change of influence area, some proper reduction factors are given for columns which support more than one floor. Using the live load models developed for colons supporting single floor, in this study, the probabilistic characteristics of multi-story column loads are analyzed. In addition reduction factors given for multi-story columns in current practice are calibrated.

In this paper, the performance of the noncoherent code tracking loop designed at baseband for CDMA applications is analyzed in detail and is confirmed by computer simulations. Analytical closed-form formula for jitter variance is derived for AWGN channel environments as a function of pulse shaping filter, timing offset, signal-to-interference ratio, and loop filter coefficients. The design issue of the loop filter is also addressed with emphasis on the second-order tracking loop. Finally, the performance of the designed tracking loop is examined by computer simulations for both AWGN and Rayleigh fading channels, when applied to the reverse link of the coherent CDMA system for IMT-2000 designed by ETRI.

Purpose: This study was done to identify differences in work environment, work stress, turnover intention and burnout and investigate the relationship among these variables in nurses in Korean Neonatal Intensive Care Units. Method: Participants were 242 nurses working in 13 general hospitals. Burnout was measured by the Maslach Burnout Inventory (MBI), work stress with the instrument by Gu & Kim (1994), and turnover intention with the scale by Kim & Lee (2001). Size of the NICU, nurse to patient ratio, and communication satisfaction were included in work environment. Data were analyzed using Pearson correlation coefficients and multiple regression analysis with SPSS WIN program. Results: The mean score for work stress in NICU nurses was 3.43 points, for burnout, 2.72 points, and for turnover intention, 4.64 points. Burnout and turnover intention level of participants were moderate-high. Work stress, communication dissatisfaction with physician, and clinical career accounted for 33% of variance in burnout. Significant differences were found between size of NICU and staffing related to environmental characteristics in turnover intention and burnout. Conclusions: Results indicate that effective communication with coworkers and institutional support for appropriate staffing according to number of beds will help to prevent work stress, burnout, and ultimately, nurses' resignations.
