Many bioinformatics sites have managed local bio-databases, including major databases such as GenBank and PIR with update load. We have developed several programs to monitor the update status of these databases and to FTP them automatically. These programs can be used for maintaining local bio-databases as recent versions and providing up-to-date databases through FTP sites. Currently, the program serves major bio-databases and will extend to accommodate many more bio-databases.

전통적인 IDS는 단일 시스템, 단일 환경하의 침입 탐지만을 제공하므로, 보안대상 제한, 유연성 한계, 다양한 형태의 침입탐지 불가 등의 문제점이 대두되고 있다. 최근 이러한 문제점을 해결하기 위하여 여러 IDS의 침입정보를 통합, 분석하는 연구가 활발히 진행되고 있다. IDWG는 IDS간 상호운용을 지원하고자 침입정보 전송 프로토콜과 메시지 친환 형태를 표준화하는 작업을 진행하고 있다. 본 논문은 이 기종 IDS 관리 및 침입정보 통합을 위한 테스트베드 구축 과정을 제시한다. 단위 IDS는 Snort와 Snare를 사용하였으며, 국제표준을 준수하는 RoadRunner 라이브러리를 이용하였다.

Cloud computing that provide a elastic computing service is more complex compared to the existing computing systems. Accordingly, it has become increasingly important to maintain the stability and reliability of the computing system. And troubleshooting and real-time monitoring to address these challenges must be performed essentially. For these goals, the handling of the log data is needed, but this task in cloud computing environment may be more difficult compared to the traditional logging system. In addition, there are another challenges in order to have the admissibility of the collected log data in court. In this paper, we design secure logging service that provides the management and reliability of log data in a cloud computing environment and then analyze the proposed system.

Web-Based instruction system implemented according to CGI based process-oriented. But, in case of system development, theses method is able to take inefficiency with duplication of program code. Also, ofter the development, it takes difficult on the operation and management. In this research, I implement Web-based score processing system by component composition. Applied component model is Java Beans and composition method is to use Chiron-2 architecture. By this method, this research shows the high efficiency - not only structural advance but also low value of cyclomatic complex that measure a maintenance.

In the legislation interpretation and fundamental viewpoint about the legal system of insider trading, Japan strictly legislate under the proposition, the principle of 'nulla poena,' adopted 'the principle of limited enumeration,' and United states, under 'the principle of comprehension,' has entrusted courts with establishment of concrete concepts and standard, so the courts are very flexible in determining the range of insiders and the importance of inside information to show a strong will to eradicate insider trading. Korea has a legislative position of 'the principle of limited indication' which has been created by the negotiation between those principles of United states and Japan. Though this court has interpreted insider trading, insider trading using non-disclosed information has increased lately, needing the strengthening of its regulations. However, this shows us that sophisticate the regulations may be, the exposure of insider trading has limitations. The most important thing is to change recognition for transparency of the securities market, security of investors and to establish the atmosphere which is that fair stock trading made in a sound capital market to raise funds for corporation. The policies of improving unfair trading, self-regulation bodies, raising the transparency and legality of procedures of supervision and monitoring and applying 'compliance program' to stock companies are very needed to eliminate unfair trading in the securities market and establish the order of trading.

Top manager and factory manager in the small-medium industrial factory in Korea was conscious of industrial education training requirement more than past, it began the Saemaul movement in factory from 1974, and the 1st nation wide meeting of industrial Standardization & Quality control Movement from 1975, etc. It is that industrial education training through the influence of pan-industrial nation with program. Because it is non-system and unplanned that are a short period introduction of industrial education training operation. Now then they are received better apprecation through the information of the program ecommendation and consultancy of industrial education training from coordination with related professional agencies and goverment agency for small-medium industry promotion.

The information on the incoming load to wastewater treatment plants is not often available to apply to evaluate effects of control actions on the field plant. In this study, a time series model was developed to forecast influent flow rate, BOD, COD, SS, TN and TP concentrations using field operating data. The developed time series model could predict 1 day ahead forecasting results accurately. The coefficient of determination between measured data and 1 day ahead forecasting results has a range from 0.8898 to 0.9971. So, the corelation is relatively high. We made forecasting program based on the time series model developed and hope that the program will assist the operators in the stable operation in wastewater treatment plants.

The growing use of public blockchain-based virtual cryptocurrency calls for secure management of blockchain account information managed through cryptocurrency wallet programs. The previously proposed wallet program has high security in terms of managing an account's private key, but low security in managing an account's recovery phrase. Therefore, in this paper, we propose a safe management system of blockchain account recovery string based on the new user authentication method using the user's mobile device information and OTP technique to overcome the problem of the existing account recovery string management method. It also conducts an analysis of the proposed blockchain account recovery string management system based on the expected behavior scenario.

In this study, we propose an information providing and learning system using augmented reality in the exhibition (museum, performance) environment. In a typical exhibition space, a description of a picture or a photograph is provided in a printed matter or a space in the form of an information space (explanatory space), or an auxiliary explanation using an 'audio guide' or a 'docent' program. Augmented reality technology is applied to the exhibition space in the form of a fusion of these methods, and the description of the exhibition is provided to the user in various forms such as text, picture, audio and image, thereby providing stereoscopic information and learning. We apply the augmented reality technology in a specific exhibition space and utilize it as a tool of providing information and learning using image description of pictures.

To enhancing the exercise effect, exercise management systems are introduced and generally used. They create the proper exercise program through exercise prescription after determining the personal body status. When the exercise programs are created, they will consider $2weeks{\sim}3months$ period. And, existing exercise programs cannot respect with personal exercise habits or exercise period which are changing variedly. If exercise period is long, it can be caused inappropriate exercise about user current status. To solve these problems in legacy systems, this paper proposes a Context Aware Exercise Model (CAEM) to provide the exercise program considering the user context. Also, we implemented that as Intelligent Fitness Guide (IFG) System. The IFG system is selectively received necessary measurement values as input values according to user's context. If exercise kinds, frequency and strength of user are changing, that system creates the exercise program through exercise optimization algorithm and exercise knowledge base. As IFG is providing the exercise program in a real time, it can be managed the effective exercise according to user context.
