Purpose: The purposes of this study were to examine health-related quality of life and to identify the mediating effect of resilience on the relationship among uncertainty, distress, and health-related quality of life in lung cancer patients. Methods: A total of 149 lung cancer patients visiting the D hospital in B city completed a questionnaire, including demographic and disease-specific characteristics, uncertainty, distress, resilience, and health-related quality of life. Data were analyzed with descriptive analysis, t-tests, ANOVA, and multiple regression analyses via SPSS 24. Results: Health-related quality of life was $81.00{\pm}21.39$ (range 0~136) in lung cancer patients. In the results of hierarchical regression analyses, the health-related quality of life was associated with education, uncertainty, distress, and resilience. However, there was no mediating effect of resilience on the relationship among uncertainty, distress, and health-related quality of life. Conclusion: Lung cancer patients with high uncertainty and distress and low resilience could experience low health-related quality of life. In order to reduce uncertainty and distress, it is necessary to provide more detailed, systematic information and support, while reinforcing positive thinking.

This study aims to examine the effects of strategic management accounting on firm performance of finance businesses in Thailand. Strategic management accounting comprises of environmental scanning, competitor orientation and forward-looking information. In this study, 175 finance businesses in Thailand are the samples of the study. A mail survey procedure was used for data collection. The hierarchical multiple regression analysis is employed to test the research relationships. Firstly, environmental scanning positively affects operational excellence, organizational effectiveness and firm performance. Secondly, competitor orientation is positively related to managerial efficiency and organizational effectiveness. Thirdly, forward-looking information has a positive influence on operational excellence, managerial efficiency, organizational effectiveness, and firm performance. In addition, operational excellence, managerial efficiency and organizational effectiveness have positive impact on firm performance. Finally, to verify the mediating effects, operational excellence, managerial efficiency and organizational effectiveness are the mediators of the research relationships. This study confirms that all dimensions of strategic management accounting play a significant role in determining business outcome as being congruent with the theory of resource-based views of the firms. Executives of firms need to provide valuable resources and capabilities to support the strategic management accounting implementation in order to achieve good business outcome in highly competitive environments.

The main aim of study is to identify the factors that affect the purchasing intention of young adults. The reference group is an important factor in determining the underlying causes of young adults' purchasing intentions. However, the literature states that young adults prefer to buy brands they trust in order to eliminate the risks that may arise when buying products they may not know. Moving from this perspective, the study proposes a conceptual model that including structural relationships between brand trust, reference group, and purchasing intention. The study aims to contribute to the literature by discussing the moderator role of brand trust in this structure. A series of hypotheses are tested via a survey completed by 749 young people between the ages of 20 and 30 living in Istanbul, Turkey. The data were analyzed with IBM SPSS-23 and AMOS-18 program. In addition to descriptive, reliability, and factor (exploratory and confirmatory) analysis, hierarchical regression analysis was performed to test the research hypotheses. The results show that the reference group positively influences the purchasing intention, and brand trust plays a moderating role in this relationship. The findings are discussed and some practical suggestions are made for mobile phone manufacturers.

Mobile IP has been designed only to maintain communication as they move form place to place, so it doesn't guarantee Quality of Service(QoS). QoS in mobile IP is important to provide multimedia and real-time applications services in mobile, and it is closely related to handoff delay. Therefore, handoff delay problem is actively studied to guarantee QoS as a main issue in mobile IP research area Next generation Mobile IPv6 resolve this problem somewhat, triangle problem for first packet and handoff delay still remain. In this paper, we suggest SNMP Information-based routing that adds keyword management method to Information-based routing in active network in order to resolve such a problem, and then suggest QoS controlled handoff based on SNMP Information-Based routing. After modeling of suggested method and existing handoff method simulations we carried out with NS-2 for performance evaluation. The results of simulations show the some improvement on handoff delay, and therefore on QoS improvement.

Multiprocessor system is efficient and high performance architecture to overcome a limitation of single core SoC. In this paper, we propose a multiprocessor SoC (MPSoC) architecture which provides the low complexity and the high performance. The dynamic routing scheme has a serious problem in which the complexity of routing increases exponentially. We solve this problem by making a cluster with several PEs (Processing Element). In inter-cluster network, we use deterministic routing scheme and in intra-cluster network, we use dynamic routing scheme. In order to control the hierarchical network, we propose efficient router architecture by using smart crossbar switch. We modeled 2-D mesh topology and used simulator based on C/C++. The results of this routing scheme show that our approach has less complexity and improved throughput as compared with the pure deterministic routing architecture and the pure dynamic routing architecture.

Nowadays meteorological information is systemized as a useful knowledge which has a significant effect on the overall industrial domains over the simple data. The distribution industry, which has the short life cycle, depends on the meteorological information at the strategic level. However, it is necessary to pay attention to the continuous investment in meteorological information because there is a hostility to paying for a service, particularly it does not provide accurate and reliable information. Therefore, the purpose of this study is to increase the usefulness of meteorological information in the distribution industry for its economic effectiveness from the core meteorological factors. We found significant meteorological factors (temperature, precipitation, disaster) that have a critical influence on the distribution industry through the hierarchical analysis process, and their importance according to the type of distribution channels, such as department store, large-scale discount store, convenience store, and home shopping. We performed the AHP analysis with 103 survey samples by middle managers from the various distribution channels. We found that precipitation is the critical meteorological factor across the distribution industry. Based on this result, we stress the difference in the level of the meteorological information in order for the effectiveness of each type of distribution channels.

The purpose of study is to examine the effects of family support on the life satisfaction of elderly with disabilities and provide a ground necessary to improve it. Research was conducted on 167 elderly with hearing, visual and physical disabilities aged over 60 who were living in Seoul and Pusan. Telephone survey, sign language and interview, in accordance with types of disability, were adopted to collect data effectively. That is telephone survey was used for elderly with visual impairment whereas face-to-face interview for physical impairment and sign language for hearing impairment by volunteers. Collected data were analyzed, using hierarchical regression analysis. This study utilized two different models, direct effect model and buffering effect of social support in order to examine the effects of familial support on the life satisfaction of elderly with disabilities. Research findings suggest that the level of life satisfaction appeared to be low in general among elderly with disabilities and emotional family support exerted a positive effect on life satisfaction. In addition, it is empirically supported that emotional family support buffered the negative effect of economic limitations on life satisfaction. In other words, the effects of economic limitations as stress factor decreased with the increase in the frequency of emotional support, however, the level of life satisfaction decreased at a mercy of the stress factor of economic limitations with the decrease in the frequency of emotional support. Finally, this paper attempted to provide some alternatives to effectively improve life satisfaction among elderly with disabilities based on empirical findings.
