최근 윈도우의 취약점을 이용하는 웜 및 바이러스로 인한 정보시스템과 네트워크에 대한 피해가 급속히 증가하고 있다. 윈도우의 취약점을 이용한 공격에 대한 해결방법은 해당 취약점은 적시에 신속하게 패치를 설치하는 것이다. 본 논문에서는 기존의 패치관리시스템이 관리자의 개입을 요구하기 때문에 패치를 신속하게 적용할 수 없는 단점을 보완하여, XML 기술을 기반으로 MS 다운로드 센터에서 패치를 자동으로 다운받아 클라이언트까지 자동으로 보안패치파일을 설치하는 보안패치 자동관리 시스템을 제안한다.

Multiple sequence alignment is a useful tool to identify the relationships among protein sequences. Dynamic programming is the most widely used algorithm to obtain multiple sequence alignment with optimal cost. However dynamic programming cannot be applied to certain cost function due its drawback and to produce optimal multiple sequence alignment. We proposed sub-alignment refinement algorithm to overcome the problem of dynamic programming and impelmented this algorithm as a module of our MS Windows-based sequence alignment program.

This study is intended to analyze the condition of management about the apartment houses in Israel. The subjects of the study were 32 house-committees who live in Jerusalem and Haifa, and who were interviewed by structured questionnaire from the 1st of April through the 30th of May 1997. The statistical methods used for the study were: frequency, percentage, mean, t-test and ANOVA by the SPSS for MS Windows Release 6.0 program. The main results of this study are as follows: 1) The most house-committee members were elected by the residents who attend the annual meeting. 2) The period of management of the committee was average of 4.1 years. 3) The tasks of the committee were to collect the management fee and make the contracts for cleaning and gardening for buildings. 4) The opinion about having the professional managers was negative. 5) The major issues of the committee were being supported by either the local authority or the other organizations which are related to housing management.

In the present study, a post-processing program is developed for 3D data visualization and analysis. Because the graphical user interface(GUI) of the program is based on Qt-library while all the graphic rendering is performed with OpenGL library, the program runs on not only MS Windows but also UNU and Linux systems without modifying source code. The structure of the program is designed according to the object-oriented programming(OOP) concept so that it has extensibility, reusability, and easiness compared to those by procedural programming. The program is organized as modules by classes, and these classes are made to function through inheritance and cooperation which is an important and valuable concept of object-oriented programming. The major functions realized so far which include mesh plot, contour plot, vector plot, streamline plot, and boundary plot are demonstrated and the relevant algorithms are described.

Fracture toughness database system was developed with Visual Foxpro 6.0 and operates in MS Windows environment. The database system contains 10,278 sets of $K_{IC}$ data, 7,046 sets of $K_{C}$ data, 784 sets of $J_{IC}$ data, 571 sets of CTOD data, 62 sets of $K_{a}$ data and 26 sets of $K_{Id}$ data. The data were collected from JSMS(Society of Material Science, Japan) fracture toughness data book and USAF(United States Air Force) crack growth database. In addition, the database was applied to predicting $K_{IC}$ from tensile material properties using artificial neural networks.

Developed in this paper a mass-spring engine to represent and manipulate deformable objects. The deformable object model is a basic technology in the ‘Tangible Space Initiative’. The mass-spring model consists of structural, shear and bending springs. Various forces like external, friction, gravity, spring, and damping forces are considered and collision with planes and spheres are treated. When a sphere collide mass-spring model, mass-spring engine calculates external force to interface mass-spring model. A prototype system is implemented in C on an MS windows machine.

This study develops and operating software for a model plant. The model plant consists of an AS/RS system, two machining centers, an assembly line, and supplementary material handling equipments. Devices of each component are connected with the IBS RT24 DIO 16/16-T I/O module. Each I/O module communicates digital signals with the INTERBUS controller board via SUB-D 9 Connector cable. This study is a previous stage for developing an educational CIM software. Petri Nets is used for modelling the storage/retrieval of the AS/RS system, the flow of workpieces and the assembly line for parts. The operating software is coded with Microsoft Visual $C^{++}$ 5.0 and Interbus Library which is a software driver for the controller board. The operating software can be run on a MS Windows 95. Microsoft Access is used for the implementation of databases for BOM, AS/RS, and parts.

In this study, the prototype of a system for checking risk-factor of NC machine is proposed. The proposed system can get the risk-related information by monitoring the status of real-time processes of NC machines. Using the information, the accidents can be prevented by the background process of an expert system tool. This paper consists of 2 parts: (1) the method for gathering data and definition of the risk-related factors of NC machines and (2) the procedure for finding the proper actions by using the forward chaining of a rule-base. Proposed system is implemented with C++ language under MS-windows.
