Objectives: To explore alcohol perceptions and their association hazardous alcohol use in the populations of Alberta, Canada and Queensland, Australia. Methods: Data from 2500 participants of the 2013 Alberta Survey and the 2013 Queensland Social Survey was analyzed. Regression analyses were used to explore the association between alcohol perceptions and its association with hazardous alcohol use. Results: Greater hazardous alcohol use was found in Queenslanders than Albertans (p<0.001). Overall, people with hazardous alcohol were less likely to believe that alcohol use contributes to health problems (odds ratio [OR], 0.46; 95% confidence interval [CI], 0.27 to 0.78; p<0.01) and to a higher risk of injuries (OR, 0.54; 95% CI, 0.33 to 0.90; p<0.05). Albertans with hazardous alcohol use were less likely to believe that alcohol contributes to health problems (OR, 0.48; 95% CI, 0.26 to 0.92; p<0.05) and were also less likely to choose a highly effective strategy as the best way for the government to reduce alcohol problems (OR, 0.63; 95% CI, 0.43 to 0.91; p=0.01). Queenslanders with hazardous alcohol use were less likely to believe that alcohol was a major contributor to injury (OR, 0.39; 95% CI, 0.20 to 0.77; p<0.01). Conclusions: Our results suggest that people with hazardous alcohol use tend to underestimate the negative effect of alcohol consumption on health and its contribution to injuries. In addition, Albertans with hazardous alcohol use were less in favor of strategies considered highly effective to reduce alcohol harm, probably because they perceive them as a potential threat to their own alcohol consumption. These findings represent valuable sources of information for local health authorities and policymakers when designing suitable strategies to target alcohol-related problems.

오늘날 '정보화사회' 구축은 국가경쟁력 획득에 중요한 수단이 된다. 특히, 우리나라는 전 세계적으로 성공적인 정보화 구축 대표 사례로 평가 받고 있다. 이와는 반대로 북한은 심각한 '정보격차' 문제로 인해 그렇지 못한 실정이다. 이러한 정보격차의 발생원인으로는 세 가지 측면이 있다. 첫째, 매체접근성, 둘째, 정보동원력, 셋째, 정보의식이다. 이러한 세가지 측면을 바탕으로 통일 이후 북한지역의 정보화 구축 과정에 대해 설계 제안한다. 본 연구의 목적은 통일시대를 대비해 어떻게 북한 지역의 정보화 구축을 할 것인가에 대해 단계별 실행 전략을 도출하고자 한다. 이를 위해 우리나라와 북한의 정보화 구축 단계들을 각각 살펴보고 추진과정을 분석하였다. 본 연구에서 제시한 실행전략이 향후 연구에 있어서 거대한 담론을 일으키는 초석이 될 수 있을 것으로 기대한다.

This research conducted between March and December of 2005 has focused on analyzing a diverse range of educational services provided by English native-speaking instructors teaching in Korea. This study includes quantitative research findings from 238 university students. This dual-semester research study focuses on our most recent Korean EFL (English as a Foreign Language) programs provided for university students who wish to improve their English ability. Many students hope to partake in lectures taught by Native English Speaking teachers (hereafter NS teachers), and many universities are also willing to open additional courses for these students. However, in order for lectures to be most effective, NS instructors need to be appropriately trained or qualified teachers in order to successfully educate their students. Furthermore, NS teachers need to constantly review their teaching styles and strategies to allow for professional development and to ensure an improvement in their teaching methodology. Overall, this research provides whole English lecture views of NS teachers that is data-driven regarding designing, implementing, evaluating, and reforming the education of English taught by NS teachers working in Korea.

This paper describes the design and implementation of a practical underwater positioning system, which is applicable for shallow water depth conditions. In this paper, two strategies are used to enhance the navigation performance. First, a low-cost acoustic-ranging-based precise navigation solution for shallow water is designed. Then, the outlier rejection algorithm is introduced by designing a velocity gate. The acoustic-ranging-based navigation is implemented by modifying the long base line solution. To enhance the tracking precision, the outlier rejection algorithm is introduced. The performance of the developed approach is evaluated using experiments. The results demonstrate that precise shallow water depth navigation can be implemented using the suggested approaches.

Wireless Sensor Networks (WSNs) are rapidly emerging because of their potential applications available in military and civilian environments. Due to unattended and hostile deployment environments, shared wireless links, and inherent resource constraints, providing high level security services is challenging in WSNs. In this paper, we revisit various security attack models and analyze them by using a well-known standard notation, Unified Modeling Language (UML). We provide a set of UML collaboration diagram and sequence diagrams of attack models witnessed in different network layers: physical, data/link, network, and transport. The proposed UML-based analysis not only can facilitate understanding of attack strategies, but can also provide a deep insight into designing/developing countermeasures in WSNs.

Most gasoline engines employ a port injection system to achieve the better fuel-air mixing. A part of injected fuels adheres to the wall or intake valve and forms a film of liquid fuel. The other is secondarily atomized by the spray-wall interaction. A better understanding of this interaction will help in designing injection systems and controlling the strategies to improve engine performance and exhaust emissions. In the present research, the spray-wall interaction was investigated by a laser sheet visualization method. The shape of sprays was pictured at various impinging velocities and angles. The fuel dispersion was estimated by fluorescence light, and the atomization was evaluated by the enlarged images of droplets. The experimental results were compared with model predictions which are based on OPT method. The model has been modified to have the better agreement with the experimental result, and was implemented in the KIVA-II code.

Automatic identification of Chinese personal names in unrestricted texts is a key task in Chinese word segmentation, and can affect other NLP tasks such as word segmentation and information retrieval, if it is not properly addressed. This paper (1) demonstrates the problems of Chinese personal name identification in some If applications, (2) analyzes the structure of Chinese personal names, and (3) further presents the relevant processing strategies. The geographical differences of Chinese personal names between Beijing and Hong Kong are highlighted at the end. It shows that variation in names across different Chinese communities constitutes a critical factor in designing Chinese personal name Identification algorithm.

In this paper, we discuss how to operate a buffer yard in an automated container terminal, which will be used for resolving the difficulties to which the interaction between external manned trucks and internal unmanned equipment led. The determination of fleet size of material handling equipment is an important issue in designing of buffer yard in automated container terminals. This research also addresses the issue of determining buffer capacities through simulation. By using response surface methodology (RSM) for efficient experimentation, the optimal combination of design parameters under applicable operational strategies is obtained.
