This paper examines the impact of university social responsibility on brand image and student satisfaction. Social responsibility impact on consumer behavior has been studied extensively. But the same impact has not been rigorously tested to the same extend in the education sector. Firstly, we analyze the perception of university social responsibility (USR) and its components, including (1) the quality of teaching programs, facilities, and academic staff; (2) supporting learning activities; and (3) human resource policies. Secondly, we investigate the relationship between university social responsibility, brand image, and student satisfaction. The study examined these relationships through a proposed economic model based on answers from a survey of 298 students at the University of Food Industry Ho Chi Minh City. From the above survey data, the author proceeds to quantify variables and, based on Cronbach's Alpha reliability coefficient, EFA factor analysis, and linear regression, to measure the impact of each social responsibility factor on business of the university and student satisfaction. The results show that university social responsibility actually affects the university's brand image and student satisfaction. Our findings suggest that universities should develop an appropriate marketing strategy to reinforce brand image and student satisfaction through the university social responsibility model.

멀티캐스트는 한 번의 패킷 전송으로 여러 수신노드에게 전송이 가능하다. 따라서 네트워크의 자원을 효율적으로 사용할 수 있어 일대다 환경에 적합하다. 하지만 신뢰성과 흐름제어를 기본적으로 제공하지 않아 시간제약을 갖는 멀티미디어 데이터 전송에 적합하지 않다. 본 논문에서는 멀티미디어 전송에 적합한 멀티캐스트 네트워크 모델과 네트워크 자원을 효율적으로 사용하고 멀티미디어 데이터를 수신하는 노드들의 재생품질을 보장하는 멀티캐스트 재전송 기법을 제안한다. 재전송 기법은 지역적 에러회복을 통해 송신노드에서 발생하는 응답폭주를 제거하였고 수신노드의 버퍼상태를 고려하여 시간제약을 충족할 경우 지역적 재전송을 수행하도록 하였다. 성능의 우수성을 입증하기 위해 수식과 모의실험을 수행하였다. 모의실험 결과 기존 네트워크 모델보다 낮은 네트워크 자원을 소모하며 수신노드의 QoS를 보장하는 것을 확인하였다.

A hybrid system combining renewable technologies with diesel generators is a promising solution for rural electrification. Myanmar has many renewable energy resources, and many regions that cannot be supplied with electricity from the main grid. Therefore, in this study, we select a village in Myanmar, which is located far away from the substation, and evaluate the economic feasibility of a hybrid system for the village considering the specific local conditions and resource availability. We consider a hybrid system composed of a photovoltaic source, diesel generator, battery energy storage system, and converter. The load profiles of the household data from the village, and the solar radiation profiles are determined. The advantages of the hybrid system, in terms of cost, reliability, and environmental effects are analyzed through simulations using commercial software. The simulation results show that, for the selected village in Myanmar, a hybrid system with battery energy storage can reduce the cost and greenhouse gas emissions while maintaining reliability. We also obtain an optimized design in terms of the component size for the selected hybrid system with battery energy storage.

Purpose: System consists of a lot of units with coherent function. In design phase, various units could be considered with the same function. In this study, we consider the alternative units with the same function and redundancy allocation to maximize system reliability in multi level system. Methods: The redundancy allocation problem with the alternative units in multi level system is formulated. Memetic algorithm(MA) is proposed to optimize the redundancy allocation problem. In addition, the performance of the proposed algorithm is explained by a numerical experiment. Results: MA showed better results than genetic algorithm(GA) and the convergence of the solutions in MA was also faster than GA. In addition, we could know from experiment that system reliability is increased and the chosen unit for redundancy allocation is changed if cost limit is increased. Conclusion: The chose unit for redundancy allocation is changed as resource constraints. It means we need to consider the alternative units in system design. In the future, we need to consider various problem related to redundancy allocation in multi level system and develop the better method to enhance search performance.

Purpose: This study identified the reasons why tuberculosis (TB) patients withhold treatment in a bid to develop a assessment scale to select patients who needs nursing intervention in the early stage and decrease the risk of discontinuation of treatment. Sample: There were two samples. A sample of 191 patients with TB and having primary treatment and a second sample of N who were under re-treatment Methods: The study design included qualitative and quantitative methods. Qualitative data were collected from in-depth interviews of TB patients under re-treatment. The quantitative data were collected from 191 patients with TB under primary treatment. Results: Exploratory factor analysis revealed 11 factors explaining 69.6% of total variance. These factors were categorized into four subgroups. A depression scale was used to establish concurrent validity. The depression scale had a positive relationship (r=54) with the discontinuing of primary treatment. The internal consistency reliability for the four subgroups was over .84. The confidence coefficient was Cronbach's ${\alpha}$ .95. The final scale was a self-reported four Likert scale including 50 items. Conclusion: Reliability and validity was established for the scale and the scale can be used to examine the risk of treatment discontinuation for TB. The scale is an important resource for nursing interventions in identifying and treating high risk clients.
