The purpose of this study is to understand stressors and mediators of the elderly living alone who experienced earthquakes. Based on the stress process model, in-depth interview data with five senior citizens who have experienced the Pohang earthquake were analyzed. It was found that the "earthquake" and "life in home and shelter" were primary and secondary stressors, respectively. The stress outcome was "declined health status". On the other hand, the mediators were found to be "family", "neighbor", and "life manager", which reduce stress outcomes. Also, the lack of "family" or "neighbor" resources as a mediators lead to more use of "life manager". Research results show that the role of "life manager" is as important as informal resource in the mediators for the elderly living alone. This research has the practical and policy significance of applying a theoretical model to the disaster experience of the elderly living alone and looking at the importance of "life manager" in the mediators.

The stress experienced by employees on international deployment has serious implications for their physical and mental health as well as their work performance. This study aimed to investigate the impact of resource-oriented music listening on work-related stress among employees on international deployment. The study recruited 10 participants of varying ages and occupations who had worked abroad for at least three years and conducted five personalized resource-oriented music listening sessions along with interviews. The Global Assessment of Recent Stress Scale (GARS) and Job Stress Scale (JSS) were used to measure stress levels before and after the intervention. Results showed that participants' work-related stress and perceived stress were significantly reduced following the music therapy intervention. The study also found that "awareness of own's life situation" and "self-acceptance of here and now emotional challenges" were factors that reduced regulatory stress among employees on international deployment. This study highlights the potential of resource-oriented music listening as a useful tool for managing workplace stress and promoting the well-being of expatriate employees.

지금까지의 우선이동통신에서는 주로 음성서비스를 제공하였으나 사용자들의 요구에 의해 음성서비스뿐만 아니라 점차 다양한 패킷서비스도 제공하고 있다. 일정한 자원을 사용하는 음성서비스와는 달리 패킷서비스는 서비스 타입이나 시간에 따라 자원요구량이 달라지는 특성을 지닌다. 따라서 서비스 질이 보장되는 패킷서비스를 제공하기 위해서는 자원요구량이 급변하는 패킷서비스의 특성을 잘 반영하는 무선자원 관리 메커니즘이 필요하다. 현재 패킷서비스를 제공하기 위해 개발된 UMTS망의 표준문서인 3GPP문서에는 무선자원관리를 위한 기본적인 신호체계만이 정의되어 있을뿐 자세한 알고리즘은 각 벤더들에게 일임하고 있다. 또한 여러 단말에서의 자원경쟁시 자원할당을 중재해 줄 수 있는 알고리즘은 정의되어 있지 않다. 본 논문에서는 무선자원을 공용자원과 전용자원으로 구분하고 단말의 서비스 요청시 전송하는 QoS Profile을 통해 우선순위와 초기 자원을 할당한다. 우선순위가 높은 서비스는 낮은 우선순위 서비스의 자원을 일정량 선정할 수 있게 하였다. 이렇게 함으로써 사용자가 요구하는 서비스 질을 만족시키는 동시에 가능한한 많은 패킷서비스를 받아들일 수 있는 무선자원관리 알고리즘을 제안한다.

The Lifestyle-DEPER (Decision, Execution, Personal Factors, Environment, Resources) model explains lifestyle formation. Lifestyles are shaped through the decision, execution, and habituation stages. Factors influencing the establishment of a lifestyle are categorized as environmental, resource, and personal. The environment encompasses our surroundings and social, physical, cultural, and virtual environments. Resources refer to what individuals possess, such as health, time, economic, and social resources. Personal factors include competencies, needs, and values. At the lifestyle establishment stage, each of these factors influences a different stage. These collective processes are referred to as events, encompassing both personal and social events. Health-related lifestyle factors include physical activity, nutrition, social relationships, and occupational participation. These are the goals of lifestyle intervention. The intervention strategy based on the Lifestyle-DEPER model, called KEEP (Knowledge, Evaluation, Experience, Plan), is a comprehensive approach to promoting a healthy lifestyle by considering lifestyle formation stages and their influencing factors. This study introduces the Lifestyle-DEPER model and presents a lifestyle intervention strategy (KEEP) to promote health. Further research is required to validate the practicality of the model after applying interventions based on the lifestyle construction model.

In On-Chip bus, the arbitration scheme is one of the critical factors that decide the overall system performance. The arbitration scheme used in traditional shared bus is the master-side arbitration based on the request and grant signals between multiple masters and single arbiter. In the case of the master-side arbitration, only one master and one slave can transfer the data at a time. Therefore the throughput of total bus system and the utilization of resources are decreased in the master-side arbitration. However in the slave-side arbitration, there is an arbiter at each slave port and the master just starts a transaction and waits for the slave response to proceed to the next transfer. Thus, the unit of arbitration can be a transaction or a transfer. Besides the throughput of total bus system and the utilization of resources are increased since the multiple masters can simultaneously perform transfers with independent slaves. In this paper, we implement and analyze the arbitration schemes for the Multi-Layer AHB BusMatrix based on the slave-side arbitration. We implement the slave-side arbitration schemes based on fixed priority, round robin and dynamic priority and accomplish the performance simulation to compare and analyze the performance of each arbitration scheme according to the characteristics of the master and slave. With the performance simulation, we observed that when there are few masters on critical path in a bus system, the arbitration scheme based on dynamic priority shows the maximum performance and in other cases, the arbitration scheme based on round robin shows the highest performance. In addition, the arbitration scheme with transaction based multiplexing shows higher performance than the same arbitration scheme with single transfer based switching in an application with frequent accesses to the long latency devices or memories such as SDRAM. The improvements of the arbitration scheme with transaction based multiplexing are 26%, 42% and 51%, respectively when the latency times of SDRAM are 1, 2 and 3 clock cycles.
