Understanding of a clinical trial is essential in developing clinical guideline and adopting evidence based practice. In designing and executing clinical trials, following ethical requirements should be considered : social value, scientific validity, fair subject selection, informed consent, favorable risk-benefit ratio, institutional review board, and respect for human subjects. According to the stage of drug development, purpose of trials, accumulated scientific data, clinical trials for drug development are classified as phase 1, 2, 3, and 4. Phases of clinical trials can be overlapped and the judgment of entering into the next phase should be considered highly strategically. In reading, evaluating and interpreting clinical trial reports, various skills and challenges exist. Patient sample composition, trial duration, selection of endpoints, responders and non-responders, placebo effect, patient recruitment, and extrapolation to the real world are the examples of those challenges. Treatment success will come from the well balanced approach of evidence based decision making and consideration of specific single case.

Bayesian network is a form of probabilistic graphical model. It incorporates human reasoning to deal with sparse data availability and to determine the probabilities of uncertain cases. In this research, bayesian network is adopted to model the problem of construction project cost. General information, time, cost, and material, the four main factors dominating the characteristic of construction costs, are incorporated into the model. This research presents verify a model that were conducted to illustrate the functionality and application of a decision support system for predicting the costs. The Markov Chain Monte Carlo (MCMC) method is applied to estimate parameter distributions. Furthermore, it is shown that not all the parameters are normally distributed. In addition, cost estimates based on the Gibbs output is performed. It can enhance the decision the decision-making process.

In this paper I will examine some concrete examples of the obstacles faced by non-native speakers of Japanese when learning the language. I will go on to suggest ways in which these obstacles may be overcome. Nowadays there are numerous Japanese language books available for non-native speakers. However, most of these introductory Japanese language books focus on topics such as pronunciation, accent and intonation. Notable, these introductory textbooks provide insufficient emphasis on prosodic features of the Japanese language. The Japanese language has been considered by many teachers as relatively easy compared to other languages, due to its simple phonetic structure. This may be a partial explanation of the reason why the teaching of prosodic features has generally been given insufficient emphasis. To teach Japanese efficiently at a university level I have combined an emphasis on the teaching of prosodic features together with my experience of television announcing. This has entailed using television news programmes and contemporary reading materials in my class. Using taped material I intend to describe a case-study of teaching of Japanese articulation.

This study intend to find the application methods of the FRBR model about legislation by analyzing a law life cycle from the enactment to the amendment and abolition of legislation and the type of the change after abolition. The legislation is the work as an aggregate entity consisting legal provisions and each provision is also the work. They are in the Whole-to-Part relation. The legislation has a effect by being published in the official gazette, and the updated text or the translated text is not the official version. Even if the name of the legislation is changed, it is treated as the same entity when it is not abolished and the simple rectifying text expressed in the official gazette is also legally valid. The Libraries Act has been replaced by the Libraries Act(old version), the Libraries Promotion Act, the Libraries and Reading Promotion Act and the Libraries Act(new version) in the order named, and it can be bounded into a superwork. For these examples, we provided the application method of FRBR model and suggested the actual application cases regarding Work, Expression, Manifestation and Item which are in Group 1 of FRBR model for the Libraries Act.

When 37 7th-graders learned science in cooperative learning environments, their small-group processes were audio/video taped. The verbal behaviors that appeared in cooperative learning processes were categorized, and the relationships between verbal behaviors and academic achievement were investigated. Students' verbal behaviors were classified into learning behaviors and management behaviors. Learning behaviors were further coded into giving help. reading problem, and asking help. Giving help was the most frequent behavior among the categories. In studying zero-order correlation between verbal behaviors and academic achievement, giving help and reading problem were found to have positive relationships with academic achievement. Giving specific content, which is a subcategory of giving help. showed the closest correlation with academic achievement. In studying partial correlation between verbal behaviors and the improvement of academic achievement, only application subtest score. which demands higher-order thinking, was positively related with some verbal behaviors including giving specific content.

T'oegye placed great emphasis on the cultivation of quiet-sitting. His idea of quiet-sitting, like Zhu Xi's, had various therapeutic effects as well. This can be highlighted as a real-life practice and a diverse application of the "abiding by Gyong" that he stressed; it is also associated with the treatment of physical diseases, composure in the mind, the benefits of reading, meditation in solitude, and many other areas. And We can easily infer that T'oegye would have set some premises before referring to Hualin Simbang. First, he would have been wary of quiet-sitting being the goal of cultivation: Too much obsession with and emphasis on Toinsul would actually obstruct the practice of "abiding by Gyong" and mislead one's effort for the "preservation and nourishment of the mind" and "reflection and examination." T'oegye would have probably used the physical and breathing exercises in Hualyin Simbang mainly as a reference to treat his physical illnesses. Also, his Toinsul would have been employed independently and partially as a sort of supplementary practice-without being used in parallel with quiet-sitting as one of the methods to achieve reverent seriousness.

The quick-response (QR) code is a two-dimensional barcode which is widely being used. Due to several interesting features such as small code size, high error correction capabilities, easy code generation and reading process, the QR codes are used in many applications. Nowadays, a printed color QR code for offline applications is being studied to improve the information storage capacity. By multiplexing color information into the conventional black-white QR code, the storage capacity is increased, however, it is hard to extract the embedded information due to the color crosstalk and geometrical distortion. In this paper, to overcome these problems, a new type of QR code is designed based on the CMYK color model and the local spatial searching as well as the global spatial matching is introduced in the reading process. These results in the recognition rate increase. Through practical experiments, it is shown that the proposed algorithm can perform the bit recognition rate improvement of about 3% to 5%.
