In this paper, we propose a modified Alamouti-based path selection (MAPS) strategy for multihop relay communication systems, and investigate a system performance in comparison with single path selection (SPS) and Alamouti-based path selection (APS) strategies. We also investigate the effect of a channel quality on the system performance when a channel is presumably good in the first hop and the last hop, respectively. Simulation results indicate that the proposed strategy achieves a better performance and gain more diversity than APS and SPS strategies. In addition, when the channel quality in the first hop is good, the system performance is superior to the case of good channel quality in the last hop.

Under-age drinking and the overconsumption of alcohol among undergraduate students results in unnecessary physical, emotional, and intellectual problems, as well as economic losses for individuals. This issue remains an enduring educational and public health challenge. To better understand what is known and what is not known on this subject, the purpose of this article is to review past literature as it pertains to individual causal factors. The review points to the importance of considering individual resiliency in the form of drinking refusal self-efficacy and alcohol expectancy. Innovative solutions aimed at addressing these constructs among undergraduate students, such as adaptive skill-building strategies that are social context specific, advance progress in solving this

Alcohol consumption among undergraduate students in Thailand is problematic. The aim of this study was to deepen our understanding of this problem by developing a causal relationship model for the alcohol consumption behavior of undergraduate students in Thailand, and to verify the model’s concordance with empirical data. Four latent variables were considered: alcohol consumption behavior, alcohol expectancy, drinking refusal self-efficacy, and health literacy. Participants included representative 1st – 5th year undergraduate students at the Thailand National Sports University, with 600 students being selected using stratified random sampling procedures. The descriptive statistics and the causal relationship model were analyzed using LISREL 8.80. The model developed was in good agreement with the empirical data (c2=228.66, df = 79, p > 0.05 , c2/df=2.894, SRMR =0.07, RMSEA =0.06, CFI =0.99, and RFI =0.98), with all computed indices passing the stipulated criteria. On the basis of...

This descriptive research aimed to investigate Thai citizens’ perception of information on EVD, perception on threat appraisal and perception on coping response toward EVD, knowledge of EVD and attitude toward EVD prevention, EVD prevention behavior. This study also aimed to explore types and sources of information on EVD, opinion on information of EVD. Data collecting through questionnaire which quality was tested. The major study results found that perception of information on EVD, perception on threat appraisal, and perception on coping response of the respondents were in medium levels. Knowledge of EVD was in a high level. Attitude toward EVD prevention was in a medium level whereas prevention behavior to EVD was in a low level. Types and sources of information on EVD, and opinions on information of EVD were in medium levels. There were some interesting findings such as ordinary people perceived the least in term of the way to treat EVD and people misunderstood the most in term ...

The objectives of this research were to develop the model of Village Health Volunteers (VHVs) development for behavior modification for liver fluke prevention of local people in Northeast region. The study was research and development design. The research was divided into 2 phases. The first phase aimed to establish and examine the developed model by considering the model of VHVs development through a seminar of 12 experts. The second phase aimed to test the model of VHVs development, selected by simple random sampling. The sample consisted of 570 VHVs and 1,143 people in three provinces of Northeast region, TaoNgoi District Sakonnakhon Province, Selaphum District Roiet Province and Thepsatid District Chaiyaphum Province. Data were collected from the questionnaire and analyzed by using inferential statistics including t-test. The results of this research showed that: 1. The model of VHVs potential development for behavior modification for liver fluke prevention of local people in N...
