This paper describes an algorithm that can recognize gestures constructing subspace gesture symbols with hybrid feature information. The previous popular methods based on geometric feature and appearance have resulted in ambiguous output in case of recognizing between similar gesture because they use just the Position information of the hands, feet or bodily shape features. However, our proposed method can classify not only recognition of motion but also similar gestures by the partial feature information presenting which parts of body move and the global feature information including 2-dimensional bodily motion. And this method which is a simple and robust recognition algorithm can be applied in various application such surveillance system and intelligent interface systems.

This study was conducted to investigate the perception of nurse's use of physical restraints. This study is a descriptive research study for 138 nurses who work at the small hospitals under 300 beds. Statistical analysis was performed using descriptive statistics, t-test, ANOVA, and factor analysis using the SPSS statistical program. The results of this study were as follows: The overall average of the nurses' perception of physical restraint was $3.91{\pm}0.54$, and the most important reason for using a physical restraint was to protect the patient from falling out of bed($4.37{\pm}0.68$). The factor analysis showed that 'behavior, psychological symptom management($3.81{\pm}0.67$)', 'maintain medical treatment($4.11{\pm}0.60$)' and 'patient safety($4.13{\pm}0.63$)'. It is necessary to understand the characteristics and factors of nurse's use of physical restraint in small and medium hospitals. Moreover, it is also required to use minimum physical restraints for patient's safeties and rights based on accurate understanding of physical restraint's use. Therefore, it is needed to provide job training for the physical restraint that is used in various situations and to develop education and intervention program to adjust in nurses' situation.

The purpose of this study was to investigate the body size perception and appearance management behaviors of middle school boys and girls. Subjects of this study were 7 coeducational middle school boys and girls in Gwangju and 435 responses were collected from real body measurement and questionnaires. SPSS package 12.0(Kr) was used to analyze results. The results were summarized as follows: First, middle school boys and girls tended to perceive their bodies slimmer as well as obeser. It is recommended to give education for correct perception of their body sire. Second, the correlation of body size perception factor and appearance management behavior was Middle school boys and girls tended to manage their appearance using a diet rather than doing exercise in obesity distortion perception group(the group perceive obeser than real body size). It needs to be properly guided. Third, the appearance management behavior of slimness distortion perception group(the group perceive slimmer than real body size) and normal group was examined. While middle school boys did only exercise management, middle school girls did all but exercise management. Their education should be distinguished. Finally, while slimness distortion perception group did diet management in both middle school boys and girls, they tended not to manage body correction or exercise. A tendency to depend only on a diet in the group who should perceive their need of exercise should be corrected. In order to correct the distorted body perception and appearance management behavior of middle school boys and girls, it is recommended to educate a standard body size through home management education which is a regular curriculum, and at the same time to guide them to perceive their actual body size correct.

The purpose of this study was conducted to investigate the perception and attitude toward physical restraints among elderly care workers. The subjects were 153 care workers who are working at elderly care facilities within the regions. Data were collected by structured questionnaires. Collected data were analyzed using descriptive statistics, t-test, ANOVA, $Scheff{\acute{e}}$ test and Pearson Correlation Coefficient. The mean score of the perception for physical restraints was 2.83 out of 5, and the mean score of the attitude for the physical restraints was 3.56 out of 5. There was a statistically significant positive correlation between the perception and attitude about physical restraints (r=.31, p<.001). This research has confirmed that it is necessary for care workers to have education about low score items of recognition and attitude about physical restraints. Therefore, we need to develop proper and efficient educational program about use method for physical restraints, and need to develop guideline for adopting physical restraints. Also, we should make efforts and attentions to reduce or abolish physical restraints in order to protect the elderly human rights.

This study was to investigate sociocultural attitude toward appearance, body image, and self-esteem predict the appearance management in middle and high school girls. A descriptive compare design was used with self-report questionnaires, which were completed by 384 subjects. Data was analyzed with t-test and regression. There were statistically significant differences in sociocultural attitude toward appearance (internalization, awareness), body image (appearance evaluation, appearance orientation, body area satisfaction), and appearance management (weight management, cloth management, face management) between the two groups. Regression analysis revealed sociocultural attitude toward appearance (internalization, awareness) and appearance orientation of body image were predictors of appearance management in middle school girls. The significant predictors of appearance management for high school girls were body image (appearance evaluation, appearance orientation, body area satisfaction). The study gives new suggestions that there is necessary different methods to educate and council for appearance management in middle and high school girls.

The purpose of this study is to provide basic data for improving life satisfaction by verifying the mediating effect of self-esteem in the relationship between physical health awareness, depression, self-esteem, and life satisfaction of middle-aged. Analysis data were collected through online and offline questionnaires for 320 middle-aged people for 10 days from August 15, 2021, and the SPSS WIN 23.0 program was used. As for the analysis method, frequency analysis, descriptive statistical analysis, and correlation analysis Baron & Kenny (1986) were performed in three stages of regression analysis. The research results showed First, that physical health awareness and depression of middle-aged people had a statistically significant effect on life satisfaction. Second, in the relationship between physical health awareness and life satisfaction, self-esteem showed a partial mediating effect. Third, in the relationship between depression and life satisfaction, self-esteem showed a partial mediating effect. In other words, in order to improve life satisfaction for middle-aged people, the basis for improving physical health awareness and self-esteem and reducing depression was prepared, and implications and suggestions for practice were presented.

Although the use of physical restraints is controversial, it is still commonly used in hospitalized patients to prevent patient accidents in clinical practice. It is, therefore, necessary to evaluate the knowledge, attitude, perception, and nursing practices related to the use of physical restraints. This was a cross-sectional descriptive study in which self-administered questionnaires were collected from 144 nursing students at two Universities. Descriptive statistics, including t-test, one-way ANOVA, Pearson correlation coefficients, and multiple regression, were applied to analyze the data collected. Our results reveal that the mean knowledge score of nursing students regarding the use of physical restraints was 11.55±2.81, the mean attitude score was 60.01±7.24, the mean perception score was 59.97±10.68, and the mean nursing practice score was 38.04±4.15. Significant positive correlations were observed between nursing practice and knowledge, attitude, and perception. Multiple regression analysis showed that the factors significantly related to nursing practice and the use of physical restraints were perception (β=.23, p=.005) and attitude (β=.21, p=.009), having a total explained variance of 13.0%. The findings from this study suggest that perception is the strongest predictor of the use of physical restraints in nursing practice. Thus, it is necessary to develop and apply an evidence-based educational intervention program to ensure that nursing students correctly understand the need for physical restraints and later use them appropriately in clinical practice.
