In this paper, we propose a novel model and authoring method of digital contents which improves the educational effects in the area of cyber educations through Web. Especially we offer a new model of contents authoring for engineering departs using JAVA technology and concept-based branch strategy, making unit-contents separated in accordance with their characteristics and then accessing them at arbitrary instant in the replaying time. In proportion to the proposed model and strategy, the resultant contents might show advanced adaptabilities and interactions for users and the educational effects are really improved. Combining and realizing the proposed conceptual branch method and JAVA applet library with the conventional page-branch or subject-blanch we expect to get a novel basic scenario of engineering cyber contents and the scenario might improve the authoring and educational effects of the contents by applying its good interactive properties and realistic operations.

This article suggests integrated neural network models for the interest rate forecasting using change point detection. The basic concept of proposed model is to obtain intervals divided by change point, to identify them as change-point groups, and to involve them in interest rate forecasting. the proposed models consist of three stages. The first stage is to detect successive change points in interest rate dataset. The second stage is to forecast change-point group with data mining classifiers. The final stage is to forecast the desired output with BPN. Based on this structure, we propose three integrated neural network models in terms of data mining classifier: (1) multivariate discriminant analysis (MDA)-supported neural network model, (2) case based reasoning (CBR)-supported neural network model and (3) backpropagation neural networks (BPN)-supported neural network model. Subsequently, we compare these models with a neural networks (BPN)-supported neural network model. Subsequently, we compare these models with a neural network model alone and, in addition, determine which of three classifiers (MDA, CBR and BPN) can perform better. This article is then to examine the predictability of integrated neural network models for interest rate forecasting using change-point detection.

"Gyeongbangsilheomrok(經方實驗錄)" is a book that was written for the propagation of the thought of Gyeongbang(經方) theory in the early 20th century. Gyeongbang means the medicine in "Sanghanron(傷寒雜病論)" which was written by Jangjonggyeong(張仲景), who is known as a great doctor of ancient times in China. Gyeongbang had worked as a good model of medicine for a long time, but as time goes by, there appeared some physicians pointing out the limit of Gyeongbang and trying to overcome it. Through the effort like this, there gradually had appeared so many physicians carrying out the medical treatment which was getting out of the boundary of Gyeongbang. And There also had appeared a group of physicians, called Gyeongbangpa(經方派), opposing the opinion like this and defending the academic value of Gyeongbang. "Gyeongbangsilheomrok" had been estimated as a meaningful achievement of Gyeongbangpa tradition, and also had been regarded as a good book comprising copious basic theory about Bangje(方劑). The most significant assertion in this book is that it explained the Onbyeong(溫病) theory as a component itself in "Sanghanron(傷寒論)", which had been argued by many other medicians thinking that "Sanghanron" did not cover the treatment of Onbyeong. In regarding to this problem, "Gyeongbangsilheomrok" argued that the concept of Onbyeong in "Sanghanron" belongs to the category of Taeyangbyeong(太陽病) and also suggested that Galgeuntang(葛根湯) would be the main recipe for Onbyeong.

We in this note consider a new concept, so called $\pi$-McCoy, which unifies McCoy rings and IFP rings. The classes of McCoy rings and IFP rings do not contain full matrix rings and upper (lower) triangular matrix rings, but the class of $\pi$-McCoy rings contain upper (lower) triangular matrix rings and many kinds of full matrix rings. We first study the basic structure of $\pi$-McCoy rings, observing the relations among $\pi$-McCoy rings, Abelian rings, 2-primal rings, directly finite rings, and ($\pi-$)regular rings. It is proved that the n by n full matrix rings ($n\geq2$) over reduced rings are not $\pi$-McCoy, finding $\pi$-McCoy matrix rings over non-reduced rings. It is shown that the $\pi$-McCoyness is preserved by polynomial rings (when they are of bounded index of nilpotency) and classical quotient rings. Several kinds of extensions of $\pi$-McCoy rings are also examined.

The basic idea of cable-stayed girder bridges is the utilization of high strength cables to provide intermediate supports for the bridge girder so that the girder can span a much longer distance. In the cable-stayed bridge, the cables exhibit nonlinear behavior because of the change in sag, due to the dead weight of the cable, which occurs with changing tension in the cable resulting from the movement of the end points of the cable as the bridge is loaded. Techniques required for the static analysis of cable-stayed bridges has been developed by many researchers. However, little work has been done on the dynamic analysis of such structures. To investigate the characteristics of the dynamic response of long-span cable-stayed bridges due to various dynamic loadings likes moving traffic loads. two different 3-D cable-stayed bridge models are considered in this study. Two models are exactly the same in structural configurations but different in finite element discretization. Modal analysis is conducted using the deformed dead-load tangent stiffness matrix. A new concept was presented by using divided a cable into several elements in order to study the effect of the cable vibration (both in-plane and swinging) on the overall bridge dynamics. The result of this study demonstrates the importance of cable vibration on the overall bridge dynamics.
