As genetic research is getting more active, data construction of genes are needed in the field of biology. Therefore, Gene Ontology Consortium has constructed genetic information by OWL, which is Ontology description language published by W3C. However, previous browsers for Gene Ontology only support simple searching mechanisms based on keyword, tree, and graph, but it is not able to search high quality information considering various relationships. In this paper, we suggest browsing technique which integratesvarious searching methods to support researchers who are doing actually experiment in biology field. Also, instead of typing a query, we propose querv generation technique which constructs query while browsing and query translation technique which translate generated query into SeRQL query It is convenient for user and enables user to obtain high quality information. And by this GO Guide browser, it has been shown that the information of Gene Ontology could be used efficiently.

The educational exchange through e-learning is working very well in such case as develop e-learning, development of various learning tools, cooperative practical use of e-learning contents, etc. However because there were no considerations of LMS(Learning Management System) interconnection when each systems were developed, the exchange through e-learning is starting to raise a problem. Especially the exchange through e-learning between university produced problem for a variety of reasons by absence of direct exchange in every case such as communication of students information, communication of lecture information, etc. Hence in this thesis, I will present designed model about efficient LMS interconnection through analysis case of exchange through e-learning and deduce problem. In the first place I define essential part for study such as lecture establishment data, lecture data, user data, class data, student learning tracking to interconnection data, then constituted data interconnection table used view by data interconnection prcess. By experiment result, the accessibility between students and professors was more convenience, and decreased work process by less data exchange. Henceforth there are researches in development of various essential parts for study, considered security of LMS interconnection.

According to IT(information technology) industry progress. our life is gradually convenient. The proliferation of environmental pollution and the threat of diseases proportional to the progress comes to be high gradually. We must prevent dangerous diseases which threatens the life of the human. Or we are bumped against irrevocable serious situation. In spite of the situation. managing one's own health against modern busy lifestyle is very difficult. Therefore, we need to manage our health situation by using sensors based on ubiquitous IT environment. In this paper. we propose a diagnostic model which is able to diagnose and prevent a cerebrovascular disease based on ubiquitous technology. Also. as a step of implementing the u-health care diagnosis system, the diagnosis model of cerebrovascular disease plays an important role to decide a clinic result. In the future, by using this model. we may improve our welfare and health.

RC(Remote Control) is a technology that can efficiently control and transfer a variety of user commands to CEs. However, the existing RCs have been required various additional features such as communication between CEs, extension of communication range, low power-consumption and bi-directional communication according to the advent of new types of CE devices and its enhanced performance. Even though RC controller has many customers' requests, it is not a simple solution because most legacies work on IR-based RC. In this paper, we propose RF4CE-based Universal Remote Control Framework using Smartphone in order to solve the many constraints of IR legacies. The proposed R-URC system is designed by RF4CE platform which is a kind of de-facto standard for CE remote control communication. From the verification scenarios using various CEs and smart phone, we can see that the proposed R-URC shows the good practical usage in terms of contents sharing and smart CE control.

Recently, as the use of smart devices is becoming more common, various and convenient services are being developed. Among these services, the Social Network Service(SNS) is easily accessible anywhere, anytime. In particular, as well as sharing information, it forms a social relationship in cyberspace to expand new connections, and the SNS account is used as an authentication means of other services to provide users with speed and convenience at all times. However, despite the many advantages of SNS, due to security vulnerabilities occurring in the interworking process with various services, accidents of personal information are constantly occurring, and it is urgent to prepare countermeasures against potential risk factors. It is a necessary situation. Therefore, in this paper, the use of SNS is expected to increase rapidly in the future, and it is expected that it will be used as the basic data for developing the countermeasures by learning the countermeasures according to the security threats of the SNS.

Automatic detection of objects in images has been one of core challenges in the areas such as computer vision and pattern analysis. Especially, with the recent deployment of personal mobile devices such as smart phone, such technology is required to be transported to them. Usually, these smart phone users are equipped with devices such as camera, GPS, and gyroscope and provide various services through user-friendly interface. However, the smart phones fail to give excellent performance due to limited system resources. In this paper, we propose a new scheme to improve object recognition performance based on pre-computation and simple local features. In the pre-processing, we first find several representative parts from similar type objects and classify them. In addition, we extract features from each classified part and train them using regression functions. For a given query image, we first find candidate representative parts and compare them with trained information to recognize objects. Through experiments, we have shown that our proposed scheme can achieve resonable performance.
