Purpose: The purpose of our study was to evaluate the effects of an exercise program on activities of daily living (ADL), balance and cognition in elderly individuals with Alzheimer’s disease and vascular dementia. Methods: Thirty-two patients with mild to moderate cognitive impairment were assigned to one of two groups: an exercise group (n=16) and a control group (n=16). The exercise group carried on regular exercise for 60 minutes a day, 4-5 times per week for 8 weeks. The exercise group participated in an exercise program (treadmill training and physical training). ADL, balance and cognitive function were evaluated before and at the end of the program using the Korean modified Bathel Index (K-MBI), the Functional independence measure (FIM), the Berg balance scale (BBS), the Balance performance monitor (BPM), and the Mini mental state examination (MMSE) in both groups. Results: There were significant exercise-induced improvements in ADL and Balance from pre to post tests; but not in MMSE. Conclusion: Exercise programs can improve ADL and balance in elderly with Alzheimer’s disease and vascular dementia.

Media industry is attempting various types of strategic innovation in the content and organization as they enter transition period. However, previous research has casually treated the organizational culture from the management and realized that cognitive/cultural differences between the specific departments yield conflicts. This means the researchers explored less on the decision-making process with the conflict between sub-groups and constituent in the organization. Our study reviewed the most positive method to achieve the innovation outcome through the conflict management within the organization based on the behavioral theory of the firm and applied computer simulation model for analysis to construct the quantitative scenario and infer the result. Conflict always found while media organization experiences innovation within the groups. However, in the long term, securing the independence through the certain state of 'anarchy' which possibly lead consensus implies significance rather to comprise collegiate system for unilateral control. In specific, this study explored the issues in 'conflict management' that has been evaded in media organization research through NK simulation model.

This research aims to develop an algorithm of optimal transducer placement using Kinetic Energy of the structural system. The structural vibration response-based health monitoring is considered one of the best for the system which requires a long-term, continuous monitoring. In its experimental modal testing, however, it is difficult to decide on the measurement locations and their number, especially for complex structures, which have a major influence on the quality of the results. In order to minimize the number of sensing operations and optimize the transducer location while maximizing the accuracy of results, this paper discusses about an optimum transducer placement criterion suitable for the identification of structural damage. As a criterion algorithm, it proposes the Kinetic Energy Optimization Technique (EOT), and then addresses the numerical issues which are subsequently applicable to actual experiment where a bridge model is used. By using the experimental data, it compares the EOT with the EIM (Effective Independence Method) which is generally used to optimize the transducer placement for the damage identification and control purposes. The comparison conclusively shows that the EOT algorithm proposed in this paper is preferable when a structure is to be instrumented with fewer sensors.

It is essential for health monitoring of a cable-stayed bridge to provide more accurate and enough information from the sensors. In experimental modal testing, the chosen measurement locations and the number of measurements have a major influence on the quality of the results. The choice is often difficult for complex structures like a cable-stayed bridge. It is extremely important a cable-stayed bridge to minimize the number of sensing operations required to monitor the structural system. In order to obtain the desired accuracy for the structural test, several issues must take into consideration. Two important issues are the number and location of response sensors. There are usually several alternative locations where different sensors can be located. On the other hand, the number of sensors might be limited due to economic constraints. Therefore, techniques such as methodologies, algorithms etc., which address the issue of limited instrumentation and its effects on resolution and accuracy in health monitoring systems are paramount to a damage diagnosis approach. This paper discusses an optimum sensor placement criterion suitable to the identification of structural damage for continuous health monitoring. A Kinetic Energy optimization technique and an Effective Independence Method are analyzed and numerical and theoretical issues are addressed for a cable-stayed bridge. Its application to a cable-stayed bridge is discussed to optimize the sensor placement for identification and control purposes.

Recently, the concept of empowerment has become popular within social work practice. Despite of this trends, we have little empirical knowledge about what empowerment practice is and how it is applicable to practice settings in Korea. This study explored how social workers perceived and experienced the concept of empowerment. We used qualitative method to solve this questions. Individual and focus group interviews were conducted to 7 social workers serving in diverse settings. Research results are as follows: Participants had common perceptions of empowerment concept despite of the different settings. They perceived power as confidence, independence, self-control. The client/worker relationships were open, nonhierarchial egalitarian and characterized by mutuality and reciprocity. They emphasized the nature of empowerment as circular and diffusive process. Also, they orientated long term practice related to impatience of social workers. Finally, those who participated in this study challenged and reinterpreted the existing traditional "professionalism". We concluded that empowerment practice might demand infinite energies, social worker's creativity, trust of clients, and that empowerment practice would be a new approach in social work practice which influence on much more population because of its diffuseness.

An improved bridgeless interleaved boost power factor correction (PFC) rectifier to improve power efficiency and component utilization is proposed in this study. With combined conventional bridgeless PFC circuit and interleaved technology, the proposed rectifier consists of two interleaved and magnetic inter-coupling boost bridgeless converter cells. Each cell operates alternatively in the critical conduction mode, which can achieve the soft-switching characteristics of the switches and increase power capacity. Auxiliary blocking diodes are employed to eliminate undesired circulating loops and reduce current-sensing noise, which are among the serious drawbacks of a dual-boost PFC rectifier. Magnetic component utilization is improved by symmetrically coupling two inductors on a unique core, which can achieve independence from each other based on the auxiliary diodes. Through the interleaved approach, each switch can operate in the whole line cycle. A simple control scheme is employed in the circuit by using a conventional interleaved controller. The operation principle and theoretical analysis of the converter are presented. A 600 W experimental prototype is built to verify the theoretical analysis and feasibility of the proposed rectifier. System efficiency reaches 97.3% with low total harmonic distortion at full load.
