Purpose: The Purpose of this study was to investigate the relationships between resourcefulness and the health promoting behavior of high school girls. Methods: The subjects of this study consisted of 117 high school girls on S girls' high school. The data was analyzed with the SPSS computer program that includes descriptive statistics, mean, standard deviation, t-test, ANOVA, Pearson correlation coefficient and multiple regression analysis. Results: The mean age of subjects was 18.0 years old. The mean score of resourcefulness was 114.2. The most frequently practiced resourcefulness item was "By changing my way of thinking, I am often able to change my feelings about almost anything". The next most frequently practiced resourcefulness item was "My self-esteem increases when I am able to overcome a bad habit". There was no difference in the degree of resourcefulness with respect to the general characteristics. The mean score of health promoting behavior was 115.2. The group whose concerns over health was shown high health promoting behavior. The health education class group was shown high health promoting behavior. There was statistically significant positive correlation between resourcefulness and health promoting behavior of high school girls. Conclusion: The findings of this study provides promising evidence to construct further studies on the increasing health promoting behavior programs relating to high school girls. To increase health promoting behavior for high school girls, it is necessary to continue or possibly expand on existing health education programs.

Objective : The purpose of this study is to know the efficacy of Korean medical treatment for recalcitrant hand and foot warts with an experience of cryotherapy. Methods : Twenty-two patients(male 12, female 10) with recalcitrant warts visited Amar Korean Medicine Clinic and were treated with herbal medicine, herbal acupuncture, acupuncture, moxibustion and bloodletting for at least 3 months. After treatment, a clearance rate was divided into 4 scales such as; complete clearance / partial clearance-good / partial clearance-poor / no change. Results : Mean age of patients was 23.4 years and mean period of disease was 43.6 months. Mean duration of treatment was 3.0 months and mean dosage(貼) of herbal medicine was 89.1. Nineteen patients(86.4%) showed complete clearance, one(4.5%) partial clearance-good, and two(9.1%) partial clearance-poor. Conclusion : This data demonstrates that Korean medical treatment could be an effective treatment for recalcitrant warts.

1. 미소한 단면적 변화율의 관재인발에서는 직접적인 방법에 의한 평균마찰계수(Mean friction coefficient)와 Sachs의 이론치가 매우 근사한 오차를 나타내므로 축방향 응력으로부터 마찰계수를 결정할 수 있다. 2. 비교적 높은 단면적 감소율의 인발에 있어서는 직접적인 방법에 의한 평균마찰계수가 Sachs등의 값 보다 더욱 실험치에 더욱 접근하므로 반경방향분력의 측정이 필요하다. 3. 봉재인발가공에 사용되는 평균마찰계수의 추정치도 관재인발의 경우에 확대 적용이 가능하다.

This paper proposed a framework for handover method in continuously tracking a person of interest across cooperative pan-tilt-zoom (PTZ) cameras. The algorithm here is based on a robust non-parametric technique for climbing density gradients to find the peak of probability distributions called the mean shift algorithm. Most tracking algorithms use only one cue (such as color). The color features are not always discriminative enough for target localization because illumination or viewpoints tend to change. Moreover the background may be of a color similar to that of the target. In our proposed system, the continuous person tracking across cooperative PTZ cameras by mean shift tracking that using color and shape histogram to be feature distributions. Color and shape distributions of interested person are used to register the target person across cameras. For the first camera, we select interested person for tracking using skin color, cloth color and boundary of body. To handover tracking process between two cameras, the second camera receives color and shape cues of a target person from the first camera and using linear color calibration to help with handover process. Our experimental results demonstrate color and shape feature in mean shift algorithm is capable for continuously and accurately track the target person across cameras.

In this study, we examine future changes in the Hadley cell (HC) strength using CMIP5 climate change simulations. The current study is an extension of a previous study by Seo et al. that used all 30 available models. Here, we select 18-23 well-performing models based on their significant internal sensitivity of the interannual HC strength variation to the latitudinal temperature gradient variation. The model projections along with simple scaling analysis show that the inter-model variability in the HC strength change is a result of the inter-model spread in the meridional temperature gradient across the subtropics for both DJF and JJA, not by the tropopause height or gross static stability change. The HC strength is expected to weaken significantly during DJF, while little change is expected in the JJA HC strength. Compared to the calculations with all model members, selected model statistics increase the linear correlation between the changes in HC strength and meridional temperature gradient by 13~23%, confirming the robust sensitivity of the HC strength to the meridional temperature gradient. Two scaling equations for the selected models predict changes in HC strength better than all-member predictions. In particular, the prediction improvement in DJF is as high as 30%. The simple scaling relations successfully predict both the ensemble-mean changes and model-to-model variations in the HC strength for both seasons.

To determine the effect of posture change on autonomic activity and to investigate valid parameters to reflex the autonomic activity from time-series pupil size data, a posture-related experiment was performed with 15 subjects, which involved measuring their electrocardiograms and pupil sizes. The experimental procedure consisted of three-sequence postures-supine, sitting and upright-for 5 minutes each, with rest sessions between postures. The subjects were notified of the entire experimental procedure. The parameters of the subjects' heart rate variability showed significant differences between the postures (heart rate: 63-70-80 beat, normalized low frequency power: 28-50-75, normalized high frequency power: 72-49-25 and ratio: 0.5-1.2-4.4 in supine-sitting-upright position respectively) as did the parameters of their mean pupil sizes (41300-53900-53700 pixels respectively) and the major frequencies (the third trend: 0.23-0.2-0.18 Hz respectively) of their pupil size variability according to changes in their autonomic activities induced by posture change. The experiment thus proved that posture change affects autonomic activity and that such activity can be estimated by the parameters of pupil size as similar as heart rate variability.

In this paper, the ventilation efficiencies of an underground sewage disposal plant were investigated for ventilating system without fan, ventilating system with eleven cross flow fans and ventilating system with sixteen cross flow fans by numerical method. It has been found that the air change effectiveness of the system without fan was predicted 0.44. It means that an additional ventilating equipment is needed to maintain good indoor air quality. For the ventilating system with sixteen cross flow fans, the air change effectiveness was predicted 0.55. The air change effectiveness of the ventilating system with eleven cross flow fans was predicted 0.51. It is known that the air change effectiveness above 0.5 is enough to eliminate pollutant and bad smell in the indoor. Therefore, it is recommended to select the ventilating system with eleven cross flow fans for the underground sewage disposal plant in an economic point of view.
