Background: This study investigated the effect of erector spinae and quadratus lumbar kinesio taping and support surface conditions on abdominal muscle activity during plank exercise. Design: Within-Group design. Methods: A total of twenty-three healthy men and women participated in this study. Abdominal muscle (both external obliques and internal oblique muscle) contraction was analyzed through EMG measurement with the presence or absence of kinesio taping applied to the erector spinae muscle and quadratus lumborum muscle during plank exercise and the difference between the support surfaces (stable surface and unstable surface) as variables. Abdominal EMG was attached to the right external oblique, left external oblique, right internal oblique, and left internal oblique. Results: The results showed that Abdominal left and right external obliques and internal obliques showed significant increases in activity when kinesio taping was applied to the erector spinae and quadratus lumborum muscles and unstable ground (p<0.05). Conclusion: In this study, we confirmed that the activity of the abdominal muscles was significantly increased during the plank operation in the state where the kinesio tape was attached. In addition, it was confirmed that the activity of the abdominal muscles was significantly increased during the plank operation on the unstable surface. These results suggest that in the state of kinesio tape attached and instability, plank motion has a positive effect on abdominal muscle activity.

Purpose: This study investigates the effect of 60° semi-squat exercises according to three different types of support surfaces. The effects were examined on joint position sense and balancing ability using stable and unstable surfaces in patients afflicted with post-stroke hemiplegia. Methods: Subjects were instructed to perform three sets of 60° semi-squat exercises according to the characteristics of the support surface conditions. The three ground states were bilateral stable surface (BSS), nonaffected side unstable surface (NUS), and bilateral unstable surface (BUS). The joint position sense, characteristics of body sway, and dynamic balance were analyzed according to floor conditions before and after the experiment. A balance-pad (50 cm W×41 cm L×6 cm H; Alcan Airex AG, Sins, Switzerland) was used for the unstable floor. Results: The 60° semi-squat exercises applied to hemiplegic patients showed the highest statistical significance in joint position sense in the NUS group, and Timed Up and Go test (TUG) in the BUS group (p<0.05). Conclusion: Functional training using an unstable surface can be applied as a meaningful intervention method for improving the balance and joint position sense of stroke patients.

We attempted to provide a way to improve job satisfaction by analyzing the relationship between the factors influencing job satisfaction directly or indirectly by the ecological system factors of long-term care worker who provide elderly care services at home benefit institutions. In this study, job satisfaction was confirmed to have a positive (+) correlation with all ecological factors except for social and cultural environmental factors by setting the causal relationship between the social and social characteristics of long-term care worker and job satisfaction as dependent variables. The factors with the highest correlation with job satisfaction were social support, followed by family support, job conditions, trust in welfare policies for the elderly, self-efficacy, and self-esteem. Therefore, it can be seen that nursing care workers who recognize positive support from the surrounding social network and family surrounding nursing care workers and positively recognize job conditions are generally positive.

Purpose: This study was conducted in order to investigate the relationships between job stress or social support and job satisfaction, and the function of social support, theoretically considered to mediate the relationship between job stress and job satisfaction. Methods: After obtaining informed consent from participants, data were collected from 122 taxi drivers. Gamma was used for testing of the first and second hypotheses. Partial Gamma was used to test the third hypothesis. Patterns of elaboration described by Babbie (1986) were selected for interpretation of the relationship among the three variable analyses. Results: First, a negative relationship was observed between job stress and job satisfaction (Gamma=-.543, p=.001) and a positive relationship was observed between social support and job satisfaction (Gamma=.741, p<.001). Second, when controlling for social support, the relationship between job stress and job satisfaction showed a decrease under conditions of both low and high social support. As for the mediating effect of social support, job stress was found to affect social support and social support was found to affect job satisfaction. Conclusion: The results showed that social support had a mediating effect between job stress and job satisfaction. Therefore, development and implementation of appropriate social support interventions is needed in order to reduce job stress and promote job satisfaction.

A questionnaire was distributed to 102 teachers who worked in non-profit, for-profit and company-operated child care centers. The relationships of demographic, work conditions, and social support variables were examined by correlation, one-way ANOVA, and multiple regressions. Results showed that working hours, salary and social support were the most important factors influencing emotional exhaustion. Higher levels of burnout were found among teachers of infants and toddlers who worked for more than 12 hours on average, teachers with lower salary, and those with a lower level of social support. Results in general indicated that shorter working hours was a very important variable for reduction in burnout among teachers of infants and toddlers.

The science and technology park movement has been developing for over 60 years. The first developments simply relied on the co-location of tenant companies and the park's host to encourage technology transfer. This is in contrast with their modern counter parts which offer a range of active links between tenant companies and host organisations as well as a raft of business development services to support technology commercialisation. Many of these sites have also become important centres in regional innovation plans. In these cases they are supported by a range of local, regional and national policies that are aimed at establishing a business, technology and social environment which support innovation. The paper examines both the business development programmes developed by science and technology parks to support technology commercialisation and the macro conditions that are now being developed to support innovation.

Early criticality prediction models that determine whether a design entity is fault-prone or not are becoming more and more important as software development projects are getting larger. Effective predictions can reduce the system development cost and improve software quality by identifying trouble-spots at early phases and proper allocation of effort and resources. Many prediction models have been proposed using statistical and machine learning methods. This paper builds a prediction model using Support Vector Machine(SVM) which is one of the most popular modern classification methods and compares its prediction performance with a well-known prediction model, BackPropagation neural network Model(BPM). SVM is known to generalize well even in high dimensional spaces under small training data conditions. In prediction performance evaluation experiments, dimensionality reduction techniques for data set are not used because the dimension of input data is too small. Experimental results show that the prediction performance of SVM model is slightly better than that of BPM and polynomial kernel function achieves better performance than other SVM kernel functions.

This study shows how community can support the work-family balance and stimulate efforts of community within it. For this purpose, community concepts are defined and its demands and resources are compared with those of work and the family, Furthermore, it will examine the conditions which individuals, couples and neighborhoods need for work since the family balance is examined through the family-friendly community index. Various examples of volunteer activities or movements within the community that will support the work-family balance of the neighbors are also demonstrated. Also, the alternatives fur healthy family support activities in Korea are suggested.

The temporary support system in Korea have been carried out generally along with installing supports, which are struts, anchors, rakers. However, most of existing support systems in application relatively have limitations such as cost increase, construction configuration, and displacement occurred with support systems. Thus, a new retaining support system(referred to as the SSR, NET No.533) was developed to solve the aforementioned problems. This study introduces the design, construction, and maintenance of the SSR system under the different construction conditions. The behavior and characteristics of the SSR system were identified based on the case studies.

The design of truss type sign support structures is based on the guidelines provided by the American Association of State Highway and Transportation Officials Standard Specifications for Highway Signs, Luminaries and Traffic Signals and the American Institute of Steel Construction Design Specifications. Using these specifications, the column design strength is normally determined using the effective length approach. This approach does not always accurately address all issues associated with frame stability, including the actual end conditions of the individual members, variations of the loads in the members, and the resulting sidesway buckling for truss type sign support structures. This paper provides insight into the problems with the simplified design approach for determining the effective lengths and discusses different approaches for overcoming these simplifications. A system buckling approach, also known as a rational buckling analysis, is used in this study to determine improved predictions for design strength of truss type sign support structures.
