Dramatic development of information technology requires new type of sales strategy to enterprise S/W dealers. That is, one should thoroughly consider diversified types of enterprise S/W and more elaborated consumer needs to establish successful sales strategy. However, various factors that should be considered in establishing enterprise S/W sales strategy are different according to types of enterprise S/W and hard to be managed systematically which led to the current situation where they have not been discussed enough. Therefore, this study introduced the relationship between the factors that affect selection of enterprise S/W using the concept of cognitive map on various enterprise S/W sales cases. Through this process, this study grouped the cognitive maps of similar cases to introduce their characteristics and made this result to be practically useful to enterprise S/W sales strategy.

These days a lot of cyber attacks are exploiting the vulnerabilities of S/W. According to the trend of vulnerabilities is announced periodically, security directions are suggested and security controls are updated with this trend. Nevertheless, cyber attacks like hacking during the year 2011 are increased by 81% compared to 2010. About 75% of these cyber attacks are exploiting the vulnerabilities of S/W itself. In this paper, we have suggested a VIR model, which is a spread model of malware infection for measuring economic loss by S/W vulnerability, by applying the SIR model which is a epidemic model. It is applied to estimate economic loss by HWP(Hangul word) S/W vulnerabilities.

This paper is purposed to develop DAQ H/W, S/W and DB which can be used in developing electrical fire alarm system or in analyzing electrical fire cause, by detecting and monitoring precursor signals which have high possibility leading to electrical fire on electrical distribution wires. In this paper, developed was DAQ H/W adopting the C8051FXXX CPU which can analyze the measurement signals of current and voltage in electrical distribution wires, other CPU was investigated in view of the best digital sampling rate on the basis of previous researches for electrical fire alarm system. Also, the S/W which can interface with DAQ H/W's communication protocol and can be applied for electrical fire causes analysis, are embodied by LabVIEW. The combined DAQ H/W and S/W could analyze efficiently normal as well as abnormal electrical signals such as RMS value, instantaneous value of current and voltage, frequency signals etc, on the electrical wires. Also, DB system was constructed for recording various analysis results for precursor signals including voltage and current signals. The results by simulator and experiment showed that the suggested scheme with DAQ H/W, S/W and DB in this paper has high usability.

This study was carried out with respect to the heat release rate (HRR) properties of building wood. Heat release characteristics were measured using a cone calorimeter (ISO 5660-1) with four kinds of wood. The time to ignition measured after the combustion in $25kW/m^2$ external heat flux was 35 to 55 s. Time to ignition of both lauan and red pine was marked with the most delayed value in each of 54 s, 55 s. The maximum heat release rate ($HRR_{peak}$) was $156.87{\sim}235.1kW/m^2$, and the risk of early fire was highest in spruce. Total heat release of red pine was obtained in the highest value with $114.2MJ/m^2$. The mean effective heat of combustion of Japanese cedar was 19.1 MJ/kg and the highest among the samples. Fire risk of wood by FPI was orderly increased from lauan ($0.2468s{\cdot}m^2/kW$), red pine ($0.2339s{\cdot}m^2/kW$), spruce ($0.2308s{\cdot}m^2/kW$) to Japanese cedar ($0.2231s{\cdot}m^2/kW$). Fire risk of wood by FGI get increased from lauan ($0.5088kW/m^2{\cdot}s$), red pine ($0.5111kW/m^2{\cdot}s$), Japanese cedar ($2.8522kW/m^2{\cdot}s$) to spruce ($3.0662kW/m^2{\cdot}s$). Therefore, the risk of fire on the heat release characteristics of woods were found that spruce and Japanese cedar showed the high value compared with the other specimens.

In most EW ES equipment, S/W is developed before H/W development. The important thing is the validity of S/W algorithm should be tested before the integration between H/W and S/W. For S/W-alone test, the digital threat signal generation for the signal analysis system is needed. This paper is proposing the simulated IF signal generation which is similar with the real signal.

본 논문에서는 현재 한국항공우주연구원에서 수신, 저장하고 있는 MODIS 영상자료에 대한 DBMS (DataBase Management System) 구축 및 DB (DataBase) data 입력 S/W 개발 결과에 대해 설명한다. 우선, MODIS 영상자료의 DBMS를 구축하기 위한 DB table를 설계하였고, 이를 근거로 Oracle 9i를 사용하여 MODIS DBMS를 구축하여 운영 중이다. MODIS DBMS에 자동으로 MODIS 영상자료의 DB data들이 입력되도록 하기 위해, 첫 번째로 Visual C++를 사용하여서 MODIS DB table에 대한 DB data를 추출하는 ‘getatt.exe’ S/W를 개발하였고, 두 번째로 Visual Basic의 ADO를 사용하여서 ‘getatt.exe’ S/W로 추출된 DB data를 MODIS DBMS에 입력하는 S/W를 개발을 마무리하였으며, ‘getatt.exe’ S/W와 MODIS DBMS 입력 S/W를 한 개의 S/W로 통합하는 작업이 완료되어, 지금현재 한국항공우주연구원 내에서 정상적으로 MODIS DBMS가 운영 중이다.
