This study used an unstable platform to change the support surface type and position of both lower limbs in order to determine changes in weight distribution and muscle including the vastus medialis, tibialis anterior, lateral hamstring, and lateral gastrocnemius of both lower limbs were evaluated during knee joint flexing and extending in a semi-squat movement in 32 hemiplegic patients. The support surface conditions applied to the lower limbs were divided into four categories: condition 1 had a stable platform for both lower limbs; condition 2 had an unstable platform for the non-hemiplegic side and a stable platform for the hemiplegic side; condition 3 had a stable platform for the non-hemiplegic side and an unstable platform for the hemiplegic side; and condition 4 had an unstable platform for both sides. The normalized EMG activity levels of muscles and weight bearing ratio of both sides in the four surface conditions were compared using repeated measures ANOVA. A significant increase was found in the weight support distribution for the hemiplegic side in flexing and extending sessions in condition 2 compared to the other conditions (p<.05). A statistically significant decrease in significant decrease in asymmetrical weight bearing in flexing and extending sessions was observed for condition 2 compared to the other conditions (p<.05). A similar significant decrease was found in differences in muscular activity for both lower limbs in condition 2 (p<.05). The muscular activity of the hemiplegic side, based on the support surface for each muscle showed a significantly greater increase in condition 2 (p<.05). An unstable platform for the non-hemiplegic side and a stable platform for the hemiplegic side therefore increased symmetry in terms of the weight support distribution rate and muscle activity of lower limbs in hemiplegic patients. The problem of postural control due to asymmetry in hemiplegic patients should be further studied with the aim of developing continuous effects of functional training based on the type and position of the support surfaces and functional improvement.

Purpose: The purpose of this study was to investigate the relationships of activity status, anxiety, depression, social support, symptom experience, and functional status in patients with lung cancer based on the theory of unpleasant symptoms. Methods: The participants for this study were 101 lung cancer patients who visited the out-patient department for treatment or follow-up at one hospital in Seoul. Data were collected from January 1 to February 8, 2013 using self-reported questionnaires and clinical records. To measure variables, the functional scale and symptom scale of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30, EORTC QLQ-Lung Cancer 13, Eastern Cooperative Oncology Group Performance Status, Hospital Anxiety and Depression Scale, and Multidimensional Scale of Perceived Social Support were used in this study. The data were analyzed using SPSS 19.0 software for Windows. Results: The symptom experience showed more severity in patients with lower activity status, higher anxiety and depression. With lower activity status and social support, functional status was lower. When anxiety, depression, and symptom experience were higher, functional status was also lower. The significant factors predicting symptom experience were depression, anxiety, activity status, and social support, which explained 57.8% of the variance. Conclusion: These results suggest that psychological factors such as anxiety and depression had a negative influence on the symptom experience of lung cancer patients. Therefore, providing emotional support based on the patients' needs prior to providing symptom management could be a useful strategy for improving symptom experience and functional status.

The purpose of this research was to develop a nursing intervention list for family caregivers. The specific steps were as follows : 1. Analyze the concept, Soobal, based on literature review and case observation. 2. Generate an initial list of defining activities for ‘Caregiver Support : Soobal’. 3. Validate the defining activities. 4. Complete the final list of defining activities. A two-round Delphi questionnaire with an adaptation of Fehring's methodology was used to establish the content validity of intervention, Caregiver Support : Soobal. The definition of ‘Caregiver Support : Soobal’ was provision of the necessary information, advocacy, and support to facilitate primary patient care by someone other than a health care professional in Korean traditional manners. Ten nurse experts participated in Round I and II of this study. They were asked to rate activities that examplified the interventions on a scale of 1 (activity is not at all characteristic) to 5 (activity is very characteristic). Round I contained 15 ‘critical’ activities and 10 ‘supporting’ activities, while round II contained 16 ‘critical’ activities and 6 ‘supporting’ activities. No activities were considered to be ‘nonsupporting’ in both round I and II. Finally, the definition and 25 defining activities were developed. Intervention, Caregiver Support : Soobal, attained an ICV score of .82. This study provides a protocol model to develop Korean nursing interventions.

PURPOSE: Scapular stability is very important to arm function during activities of daily living. The push-up plus exercise is commonly used to stabilize the shoulder muscles. In the present study, we designed an elastic shoulder band (ESB) that could be used with the push-up plus exercise and studied muscle activities of the serratus anterior (SA) and the lower and the upper trapezius (LT and UT) on stable and unstable support. METHODS: Fifteen healthy people participated in this study. Three muscles were investigated using surface EMG with and without the ESB on stable and unstable support. All subjects performed each trial three times for 7 seconds per set and rested for 30 seconds. Repeated one-way ANOVA was used for statistical analyses. RESULTS: The EMG activity of the SA was significantly different during the push-up plus exercise on stable support with the ESB compared with that on unstable support without the ESB (p<.05). However, there were no differences in the activities of UT and LT on stable and unstable support (p>.05). CONCLUSION: The ESB was effective for the activity of SA during the push-up plus exercise on stable support; therefore, it has the potential for use by people during push-up plus exercises. However, further studies are required to investigate the rehabilitation tools for patients with shoulder instability.

Thiol-ene polymerization is a versatile tool for several applications. Here we report the preparation of epoxide groups containing thiol-ene photocurable polymeric support and the covalent immobilization of ${\alpha}$-amylase onto these polymeric materials. The morphology of the polymeric support was characterized by scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) coupled with SEM was used to explore the chemical composition. The polymeric support and the immobilization of the enzyme were characterized by FTIR analysis. SEM-EDS and FTIR results showed that the enzyme was successfully covalently attached to the polymeric support. The immobilization efficiency and enzyme activity of ${\alpha}$-amylase were examined at various pH (5.0-8.0) and temperature ($30-80^{\circ}C$) values. The storage stability and reusability of immobilized ${\alpha}$-amylase were investigated. The immobilization yield was $276{\pm}1.6$ mg per gram of polymeric support. Enzyme assays demonstrated that the immobilized enzyme exhibited better thermostability than the free one. The storage stability and reusability were improved by the immobilization on this enzyme support. Free enzyme lost its activity completely within 15 days. On the other hand, the immobilized enzyme retained 86.7% of its activity after 30 days. These results confirm that ${\alpha}$-amylase was successfully immobilized and gained a more stable character compared with the free one.

Objectives: The purpose of this study was to identify personal and social environmental factors associated with physical activity and sedentary behavior among elementary school students. Methods: Cross-sectional self-reported data were collected from a conveniently clustering sample population of 1538 grade 5 to 6 students attending 19 elementary schools in Seoul metropolitan city and Gyeonggi province. Data were statistically analyzed using Chi-square test and multiple logistic regression analysis. Results: In multiple logistic regression analyses, significant factors that were associated with schoolchildren's physical activity were gender, father's job, social support for physical activity, friend support, participation in school physical education class. Father's education level, mother's job, family functioning and urban residents were significantly associated with TV viewing and gender, age, BMI(obesity), mother's job, family functioning and urban residents were significantly associated with playing computer games among elementary schoolchildren. These results showed that physical activity among elementary school students was most associated with social environmental factors and sedentary behavior among school students was most associated with personal and family environment factors. Conclusion: Health care providers should develop interventions to improve these family and social environmental factors to increase physical activity levels and to decrease sedentary behavior among elementary schoolchildren.

A vector space based augmented structural kinematic (VSASK) feature descriptor is proposed for human activity recognition. An action descriptor is built by integrating the structural and kinematic properties of the actor using vector space based augmented matrix representation. Using the local or global information separately may not provide sufficient action characteristics. The proposed action descriptor combines both the local (pose) and global (position and velocity) features using augmented matrix schema and thereby increases the robustness of the descriptor. A multiclass support vector machine (SVM) is used to learn each action descriptor for the corresponding activity classification and understanding. The performance of the proposed descriptor is experimentally analyzed using the Weizmann and KTH datasets. The average recognition rate for the Weizmann and KTH datasets is 100% and 99.89%, respectively. The computational time for the proposed descriptor learning is 0.003 seconds, which is an improvement of approximately 1.4% over the existing methods.

Background: Social support is an important factor in psycho-social well-being of cancer survivors. There is little information about level of social support and its predictors among cancer survivors in Iran or other Middle Eastern countries. The aims of present study were to determine the social support and its prediction factors among Iranian cancer survivors. Materials and Methods: In this descriptive-correlational study 187 cancer patients in one educational center and one private oncology office in northwest of Iran participated using a convenient sampling method. The data collection tool consisted of a researcher-prepared checklist and the Multidimensional Scale of Perceived Social Support Assessment (MSPSS). Data analysis was performed using SPSS statistical software with descriptive statistics and multiple linear regression analysis. Results: The total score of MSPSS was 68 from a possible score between 7 and 84. Participants believed that they received a high level of support from their family members and significant others. Multiple linear regression analysis showed that single and depressed cancer survivors and participants with lower levels of physical activity believed that they received lower levels of social support. Conclusions: Iranian cancer survivors receive high levels of social support and family members are the most important source of this support. In planning any supportive care program for Iranian cancer survivors this strength should be considered. Especially, single and depressed and patients with lower levels of physical activity need more attention.
