It is certain that the future manufacturing environment will be network-centric and spatially distributed based on Internet. Today, wide variety of distributed computing and communication technologies are available for implementing a system for product data exchange and sharing. One of the technologies that have been received most attentions for product data exchange and sharing is Product Data Management (PDM). PDM tries to integrate and manage process of data and technical documents that are connected to physical product components. In accordance to previous researches about PDM, it can be regarded as an integration tool of many different areas, which ensures that the right information is available to the right person at the right time and in the right form throughout the enterprise. PDM with Web-enabled CAD system is proposed in this paper in order to acknowledge the usefulness of the system mentioned. The system will use Web service on Visual Studio C#.Net to invoke the web application system.

In this paper, we propose a method to achieve improved number plate detection for mobile devices by applying a multiple convolutional neural network (CNN) approach. First, we processed supervised CNN-verified car detection and then we applied the detected car regions to the next supervised CNN-verifier for number plate detection. In the final step, the detected number plate regions were verified through optical character recognition by another CNN-verifier. Since mobile devices are limited in computation power, we are proposing a fast method to recognize number plates. We expect for it to be used in the field of intelligent transportation systems.

Objectives : The purpose of this study was to investigate the effects of gambling environment factors (being around gambling, gambling ad access) and irrational gambling belief on the gambling behaviors of college students who experienced sports gambling. Methods : Study participants were 240 college students with sports gambling experience. Data were collected through self-report questionnaires and analyzed with SPSS 18.0. Results : Being around gambling and sports gambling ad access have a statistically significant effect on irrational gambling beliefs, which have statistically significant statistical effects on gambling addiction. Self-regulation did not show statistically significant regulatory effects between irrational gambling beliefs and gambling addiction. Conclusions : It is necessary to take a proactive approach to minimize the negative effects of sports betting and to be aware of the rapidly changing sports gambling environment factors.

The research assesses the impact of a digital procurement (e-purjee) system for sugarcane growers in Bangladesh. The system itself is simple, transmitting purchase orders to local farmers via SMS text notification. It replaces a traditional paper-based system fraught with low reliability and delivery delays. Applying expected value theory, and using decision tree representations to depict growers' decision-making complexity in an information-asymmetric environment, we compute outcomes for the strategies and sub-strategies of ICT vs. traditional paper-based order management from the sugarcane growers' perspective. The study results show that the digital procurement system outperforms the paper-based system by tangibly reducing growers' economic losses. The digital system also appears to benefit growers non-monetarily, because of reduced uncertainty and a higher level of perceived fairness. Sugarcane growers appear to value the non-monetary benefits even higher than the economic advantages of the e-purjee system.

Economic Reliability test plans(ERTP) are proposed considering that the life time of the submitted items follow the Pareto distribution of the second kind. For various specified acceptance number, sample size and producer's risk, a minimum test termination time is obtained. A comparison of proposed plan has been made with the existing plan developed by Aslam et al. (2010). The results are explained by tables and example.

As the computer becomes a trend, interactive multimedia design can be one media to communicate the cultural knowledge. A folktale can be a powerful material to show a country's culture. In this project, we try to make the folktale content to be understood easily by implementing some cultural information background. The main aim of this project is to give a vision of the richness culture through the interactive multimedia technology. In this paper, we would like to show a flow map content, a streaming of design process and a visual interface design prototype. Finally, interactive multimedia design content is very useful for a transferring the richness culture because people tend to like a multimedia content. In order to make an effective interactive multimedia design content based on a cultural background, a designer should need to understand about users, culture, technology and the whole design process.

태아의 소뇌는 임신주수에 따라 성장하며 소뇌횡직경 길이의 측정은 태아성장 예측의 중요한 지표로 활용하고 있다. 임신주수에 따른 태아 소뇌횡직경의 성장을 회귀곡선으로 표시하였고 선형회귀방정식에서 결정계수를 얻었다. 3차원초음파를 이용한 소뇌횡직경의 측정법은 통계적으로 유의(P<0.001)하였으며, 태령을 예측함에 유용하다는 것을 알 수 있었다. 또한 성장장애가 있는 태아의 경우에도 임신주수의 예측이 가능하다. 본 연구를 기초자료로 하여 지속적인 연구가 시행된다면 정확한 임신주수 예측에 유용할 것으로 기대한다.

Over the past several decades, educational systems in many parts of the world have undergone manifold changes that have significantly affected the work environment of educators. Among other negative impacts of the globalized reforms in higher education has been the increasing prevalence of workplace bullying. The purpose of this research note is to serve different purposes: (1) examine the causes behind the changing landscape of higher education; (2) discuss previous and current research on workplace bullying; (3) introduce the methodology of the Taiwan Higher Education Faculty Survey (THEFS); (4) outline its anticipated outcome.

Purpose: The purpose of this study was to identify the influences of death perception, terminal care attitude on clinical nurses' terminal care performance for cancer patients. Methods: Data were collected through self-reported questionnaires filled by 526 nurses at a General Hospital in Seoul. Data were analyzed using a multiple regression analysis. Results: Death perception showed a positive correlation with terminal care attitude (r = .45, p < .001), while there was no correlation with terminal care performance. Additionally, terminal care attitude had a positive correlation with terminal care performance (r = .18, p < .001). The explanatory power of nurses' death perception and terminal care attitude toward terminal care performance was 14%. Conclusions: The study results imply that nurses' death perception and terminal care attitude are significant variables affecting terminal care performance.

In this paper a new sampling procedure for estimating the population mean is introduced. The performance of the new population mean estimator is discussed, along with its properties, and it is shown that the proposed method generates an unbiased estimator. The relative efficiency of the suggested estimator is computed, in regards to the simple random sample(SRS), and comparisons are made to the ranked set sampling(RSS) and extreme ranked set sampling(ERSS) estimators used for asymmetric distributions. The results indicate that the proposed estimator is more efficient than the estimators based on the ERSS. In addition, the folded ranked set sampling(FRSS) procedure has an advantage over the RSS and ERSS in that it reduces the number of unused sampling units.
