Dance movement program. Psychological wellbeing, Middle aged women, Wellbeing with depression tendency, 율동적 동작 프로그램, 우울성향 중년여성 %600an This study was designed to confirm the effects of the Dance Movement Program on psychological health in middle-age women with depression tendency. 67 women with mile to moderate depression scoring between 16-25 were selected among 235 responded to CES-D (Radloff, 1977, Cho and Kim, 1993). The 46 volunteered to participate in the study were assigned the control. 7 attritions occurred during the course of the experiment leaving thirty-nine subject : nineteen experimental and twenty control, for the final analysis. Research subjects revealed to be homogenous demographically and by health-related variables. The 50-minute Dance Movement Program was performed by the experimental group 3 times a week for eight weeks, from October 6 to November 29, 1997. Depression, life satisfaction, self efficacy were measured before and after the course of Dance Movement Program. Plasma serotonin was measured to identify its relationship with depression, Homogeneity tests revealed satisfactory level on relevant research variables. Data were analyzed by $x^2$-test, paired and unpaired t-tests. The results are as follows : 1) The hypothesis that depresson score of experimental group will decreased than control group was supported by t-test(t=2.20, P=.0021) 2) The hypothesis that life satisfaction score of experimental group will increased than control group was supported by t-test(t=1.42, P=.0049). 3) The hypothesis that self-efficacy score of experimental group will increased than control group was not supported by t-test(t=6.20, P=.0616). 4) The hypothesis that level of plasma serotonin will increased than control group was not supported by t-test(t=1.88, P=.0524) Thus, the effects of the Dance Movement Program for the improvement of psychological health gram for the improvement of psychological health for the middle-aged women with depression tendency are scientifically confirmed by this study.

The purpose of this study was to examine the relationship among perceived health status, self-esteem, self-efficacy and health promoting behavior, and to determine the predictors of health promoting behavior in post-mastectomy patients. The study, a descriptive correlational study, was done with structural questionnaires. A total of 51 post-mastectomy subjects from C university hospital in Kwang-ju, South Korea completed mail-in self-reporting questionnaires during a three month period from March to June, 1999. The data were collected using Lawstone's(1982) perceived health status scale, Rosenberg's(1965) self-esteem scale, the modified self-efficacy scale(Shere et al, 1982), and the modified health promoting lifestyle profile (Walker et al, 1987). The data obtained were analyzed according to percentage, mean and standard deviation, principal component analysis, varimax rotation, t-test, ANOVA, Pearson's correlation, and stepwise multiple regression. The results were as follows: 1. The health promoting behavior measurement resulted in six factors. Each factor was labelled as follows: self-actualization, nutrition, stress management, exercise, health responsibility and interpersonal support. The total percent of variance explained by the six factors was 58.4%. 2. The mean score of health promoting behavior was 85.92(range 58~117). The scores of six factor were nutrition 3.20, self-actualization 2.59, stress management 2.58, interpersonal support 2.58, health responsibility 2.49, and exercise 2.34 on a four point scale. 3. When the score of health promoting behavior factors were compared by general characteristics. Factor I: self-actualization, differed significantly by the frequency of pregnancy (F=3.06, p=.037). Factor II: nutrition differed significantly by drinking experience(t=-2.26, p=.028) and the pre- or post stage of menopause(F=2.69, p=078). FactorIII: stress management differed significantly depending on regularity of mensturation(t=-2.12, p= .042). FactorIV: exercise differed significantly by type of religion (F=2.49, p=.072), marital status(F=5.03, p=.010), and feeding type (F=2.64, p=.036). Factor V: health responsibility differed significantly by regularity of mensturation(t=2.18, p=.037). 4. The total health promoting behavior score was significantly related to self-esteem and perceived health status(r=.610, p.006; r= .378, p=.006). The score of selfactualization also corresponded with selfesteem and perceived health status(r=.556, p=.001; r=.343, p=.013). 5. The predictor to explain the score of health promoting behavior was self-esteem, which accounted for 37.1% of the total variance. The predictor to explain the score of self-actualization was self-esteem, which accounted for 30.9% of the total variance. The score of nutrition was primarily affected by both premenopause and drinking experience, which accounted for 13.1% and 9.5% respectively. Finally, the score of exercise was dictated by marriage, Buddhism, no experience of breast feeding, which accounted for 17%, 9.8%, & 5.2% respectively. In conclusion, self-esteem is the main predictor for health promoting behavior in post-mastectomy women. These findings suggest a need for nursing strategies which promote self-esteem in such patients.

Objective: To develop a radiomics risk score based on dynamic contrast-enhanced (DCE) MRI for prognosis prediction in patients with glioblastoma. Materials and Methods: One hundred and fifty patients (92 male [61.3%]; mean age ± standard deviation, 60.5 ± 13.5 years) with glioblastoma who underwent preoperative MRI were enrolled in the study. Six hundred and forty-two radiomic features were extracted from volume transfer constant (K^trans), fractional volume of vascular plasma space (V_p), and fractional volume of extravascular extracellular space (V_e) maps of DCE MRI, wherein the regions of interest were based on both T1-weighted contrast-enhancing areas and non-enhancing T2 hyperintense areas. Using feature selection algorithms, salient radiomic features were selected from the 642 features. Next, a radiomics risk score was developed using a weighted combination of the selected features in the discovery set (n = 105); the risk score was validated in the validation set (n = 45) by investigating the difference in prognosis between the "radiomics risk score" groups. Finally, multivariable Cox regression analysis for progression-free survival was performed using the radiomics risk score and clinical variables as covariates. Results: 16 radiomic features obtained from non-enhancing T2 hyperintense areas were selected among the 642 features identified. The radiomics risk score was used to stratify high- and low-risk groups in both the discovery and validation sets (both p < 0.001 by the log-rank test). The radiomics risk score and presence of isocitrate dehydrogenase (IDH) mutation showed independent associations with progression-free survival in opposite directions (hazard ratio, 3.56; p = 0.004 and hazard ratio, 0.34; p = 0.022, respectively). Conclusion: We developed and validated the "radiomics risk score" from the features of DCE MRI based on non-enhancing T2 hyperintense areas for risk stratification of patients with glioblastoma. It was associated with progression-free survival independently of IDH mutation status.

The effect of sex ratio on behavior and welfare indexes in broiler chickens was investigated. Five variants of the sex ratio (male to female), namely, 100:0 (T1), 75:25 (T2), 50:50 (T3), 25:75 (T4) and 0:100 (T5) were tested in broilers between the ages of 7 to 35 days. It was found that the most common behavior in all sex ratios was resting behavior, ranging over 74.4 % of total behavioral frequency. The ranges of other behavior traits of total behavior traits were as follows: pecking, 5.4 to 23.1 %; standing, 1.8 to 24.8 %, and moving, 0.6 to 11.5 %. The behavioral frequency of resting, pecking, standing and moving were not affected by the sex ratio and between male and female. But the percentage of pecking, resting and moving behavioral frequency was significantly different by the age of birds (P<0.05). Age of birds had no effect on standing behavioral frequency. It seems that gait, food pad and hock burn score were no affect by sex ratio but tend to decreased in female than male. Claw length of 21 and 35 days was not affected by sex ratio and between male and female. The duration of tonic immobility (TI- reaction) was tend to decreased age of 21 than 35 days, and female than male. Both male and female of the study, hock burn score, claw length and TI-reaction were tend to lower in T4 than other treatments. The results suggest that, when male and female broilers are reared together, sex ratio can influence broiler welfare indexes in this study.

This study was carried out investigate the effects of dietary addition of mineral and sugar on the dry matter intake, daily gain, yield grade and quality grade of Hanwoo (Bos taurus coreanae) steers. Three diets fed to steers included a control diet (concentrate mix and rice straw : C) and two treatments diet (control diet + black sugar 100 g + mineral 100 g : T1, and control diet + black sugar 150 g + mineral 50 g : T2). The results are summarized as follows; total feeding intake, body weight gain and daily gain did not show significant differences among the three treatments. Cold carcass weight was significantly (p<0.05) higher in T2 than in the other two treatments (C and T1). There was no significant difference in yield traits of back fat thickness, longissimus muscle area and yield grade among the three treatments (C, T1 and T2). Marbling score showed significantly (p<0.05) higher in order of T2 (5.67) > T1 (4.67) > C (3.67). Meat color, fat color, texture and maturity were no significant difference. Quality grade was higher in T2 than in the other two treatments (C and T1), but there was no significant difference. The results show that marbling score and quality grade of Hanwoo can be increased by high dry matter intake with feeding addition of mineral and sugar.

This study was performed to investigate the effect of ginseng saponin from Korean red ginseng on the learning and memory. Total (50, 100 mg/kg, bw) and panaxadiol saponin (15, 30 mg/kg, bw) treated groups did not show the difference of the time score and the number of error in comparison with control group. Panaxatriol saponin (15, 30 mg/kg, bw) significantly decreased both the time score and the number of error in water maze test. These results indicate that panaxatriol saponin from Korean red ginseng may improve the learning ability of rat in water multiple T-maze.

In Internet of Things (IoT) environments, billions of interconnected devices and multimedia sensors generate a huge amount of multimedia traffic. Since the environment are in general deployed as a server-centric architecture wireless sensor networks could be bottlenecks between IoT gateways and IoT devices. The bottleneck causes high power consumption of the device and triggers very heavy network overload by transmission of sensing data. The deterioration could decrease the quality of multimedia streaming service due to delay, loss, and waste of device power. Thus, in this paper, we propose a context-based adaptive multimedia streaming scheme to support enhanced QoS and low power consumption in IoT environments. The goal of the scheme is to increase quality score per voltage of the streaming service, given an adaptation algorithm with context that are classified network and hardware such as throughput, RTT, and CPU usage. From the both context, the quality score per voltage is used in the comparison of a only network context-based adaptive multimedia streaming scheme, a fixed multimedia streaming and our scheme. As a result, we achieves a high improvement that means the quality score per voltage is increased up to about 4, especially in case of resolution change.
