  • This paper reviews three commercial softwares for wind climate data analysis in wind resource assessment; WAsP/Observed Wind Climate, WindRose and Windographer. Windographer is evaluated as the best software because of its variety of input data format, analysis functions, easiness of user interface, etc. For a quantitative understanding of uncertainty depending on software selection, a benchmark is carried out with the met-mast observation dataset at the Gimnyeong Wind Turbine Performance Test Site. It is found that Weibull parameter calculation and air density correction have a dependency on the software so that such uncertainty should be considered when an analysis software is selected. It is confirmed that annual energy production calculated by WAsP using a statistical table of frequency of occurrence may have some error compared to a time-series calculation method used by the other softwares.

  • 역공학(Reverse Engineering) 기술이 진보함에 따라 컴퓨터 소프트웨어에 대한 불법 조작 및 변조 등의 위협이 증가하고 있으며, 인터넷에 공개된 단순한 도구를 이용하여 누구나 쉽게 크래킹(Cracking)을 할 수 있게 되었다. 자사의 소프트웨어를 위협으로부터 방어하고자 하는 제작사들의 노력과 이를 무력화시키고자 하는 소위 크래커들의 노력은 지금까지도 계속되고 있다. 이에 본 논문에서는 소프트웨어가 가지는 위협 모델과 크래킹 기술에 대해 분석 및 실험하고, 소프트웨어를 위협으로부터 보호하기 위한 윈도우 환경에서의 메모리 해킹 방지 시스템을 제안한다.

  • In recent, internal IT industries are suffering a severe pain due to stagnancy of business activities. Particularly, internal software industries are losing international competitiveness. As to solve this problems, the paper is studied about political plans for supporting internal software industries. The paper has two important topics which are enlarged plan of domestic demand and supplement of the expert personnel in internal software industries. The paper consists of three parts: one is plan which prevents for using illegal softwares, another is problems which is related to publication of expert programming books, and the other is If educations of governmental leading. The paper suggests realistic price of softwares, powerful inspection about illegal softwares as governmental leading, and continuous public relations for changing consumers'awareness.

  • Average illuminance and luminance can be calculated by graphical methods to a certain extent but to calculate for a wide place a suitable software is needed. Softwares suitable for this purpose have been already developed in foreign nations, but the appropriate softwares for domestic use have not been developed. Therefore a program is developed which is executable in Hangul Windows. The softwares LAPRoad, is developed to calculate luminance and illuminance distribution of road surface, as well as average luminance and illuminance, overall uniformity, longitudinal uniformity, threshold increment veilling luminance and glare. And an apparatus that measures road surface reflection properties is developed. Because the road surface reflection properties is very important in luminance calculation, then concrete road surface reflection properties were measured.

  • In this paper, the problems on Windows application for finite element structural analysis softwares are presented. These Windows application programs provide the better graphical representation of structural geometry through the GUI, and provide the integrated environment for managing various processors such as a preprocessor and a postprocessor. Two examples show the efficiency of this system which can represent various inputs and outputs concurrently on multi-windows by dialog-type.

  • Softwares including random number generation are abundant in modern informative society. But it's hard to get directly multivariate multinomial random numbers from existing softwares. Multivariate multinomial random numbers are greatly used in social and medical sciences. In this paper, we show that desired multivariate multinomial random numbers can be easily generated by the aids of existing random number generating software. Some characteristics of multivariate multinomial distribution are surveyd. Measures of association for the generated random numbers were computed and compared with population ones via simulation study.

  • Recently financial institutions in Korea are experiencing an unfamiliar challenge in terms of their operational risk management due to the volatility of global financial market and the incessant development of new financial products. In this paper, we present an AHP(Analytic Hierarchy Process) model to evaluate the effectiveness of commercial softwares for risk management in banking. The AHP model considers software's performance. utility, serviceability and durability as major evaluation criteria. The weight of each criterion is generated by the questionnaire survey given to practitioners in risk management in domestic commercial banks.
