In modern dynamic management environment, there is growing recognition that information & knowledge management systems are essential for CEO's Efficient/effective decision making, As a key component to cope with this current, we suggest the management performance analysis system based on Knowledge Discovery in Database (KDD). The system measures management performance that is considered with both VA(Value-Added), which represents stakeholder's point of view and EVA(Economic Value-Added), which represents shareholder's point of view, The relationship between management performance and some 80 financial ratios is analyzed, and then important financial ratios are drawn out. In analyzing the relationship, we applied KDD process which includes such as multidimensional cube, OLAP(On -Line Analytic Process), data mining and AHP(Analytic Hierarchy Process). To demonstrate the performance of the system, we conducted a case study using financial data over the 16-years from 1981 to 1996 of Korean automobile industry which is taken from database of KISFAS(Korea Investors Services Financial Analysis System).

The purpose of this study was to evaluate performance and subjective satisfaction of mobile phone's interface elements considering the elderly users. First, mobile phone's interface elements were outlined recent foreign and domestic studies. Then, final three mobile phone's interface elements were determined by expert rating, AHP analysis, and questionnaire analysis. Objective and subjective measures were then used to determine the effects of several specific design parameters and aging differences on performance of mobile phones. In this experiment, 38 subjects and 4 independent variables were used to measure task completion time and user's subjective satisfaction. The statistical analyses indicated significant aging differences between older people and younger people in terms of keypad type and bell sound level in performance. Significant aging differences were also found for user subjective satisfaction. It is suggested that some major results from this study be used to develop mobile phone design guidelines that are more usable and accessible for most users, particularly for older users.

Korean e-Government web site has been evaluating as a distinguished government, ranked 5th of the 119 countries in the "Global e-government readiness index report 2005" by UN in 2006. However we have to focus poor rate of utilization in proportion to its high evaluation of e-Government ranking. These reason probably did not reflect the requirements of user to build and operate e-Government web site. In this paper we will provide the important factors to consider to build and operate e-Government web site. For this, we analyze the relative importance for evaluation factors of e-Government web site using AHP(Analytic Hierarchy Process).

There are many reason for unsafety action without safety operation. The reason is no standard safety operation in company or the workers never get a enough education. Standard safety operation is prepared by paper for accurate directions and orders and operators must read the paper to prevent an error of action. Also an essential particular is safety of equipment and machine must be assumed to establish standard safety operation then safety of operations will be possible.

The efficient safety estimation for a business should analyze an accident data by considering every possible and potential factor. Thus, we consider several factors to build the safety estimation model to meet fairness and rationality. This paper present the yearly statistic data of accident from KOSHA analyze the data by industry, scale, year of service of a employee, age and other factors; build the safety estimation model for the business based on the accident report derived the analysis. The estimation model is established by the weights for accident type, degree, scale, industry, year of service, and age of the employee derived from AHP(Analytic Hierarchy Process).

Railload line design of the railroad construction project should be planed considering the variety of quantitative and qualitative factors, and needs to be selected the optimum altinative weighing from VE/LCC analysis of the planned design. The purpose of this research is for showing selecting plan of the optimum railload line and railway bridge applying VE/LCC analysis in selecting the optimum altinative of railroad construction based on quantitative and qualitative factors, such as initial construction cost, maintenance cost, owner and user's requirements. In this research showed the application plan by each stage using data analysis, function analysis, and alternative evaluation of VE/LCC analysis with AHP and LCC analysis program for the selection. This research is proved the rationality and application of the course of selecting the optimum alternative through case application

The purpose of this study is to show the problems and to suggest improvement methods on the introduction of Pharmacy Information Systems(PIS) after medical reform. Medical reform have influenced many aspects of patients, doctors and pharmacists. In the case of pharmacy, information systems have been key role in the pharmacy management after medical reform. Although one year has been passed, there are still many problems. The size of system development company, A/S, the ability of programmer and the frequent change of related laws and ordinances cause difficulties in the operation of PIS. In this paper, the case of A pharmacy in daegu was investigated for the operation of PIS. Analytic Hierarchy Process(AHP) and mathematical programming methods can be used for reducing the aspect of subjectivity and considering the resource constraints.

The accidents are often resulted from multiple causes with hardware failure and human errors. So to ensure the safety of rail operation, human error should be prevented effectively. The purpose of this paper is to present an analysis system on factors of influencing human error in korean rail industry especially for engine driver and train despatcher. To achieve it, ESFs(error shaping factors) classification system was derived from several PSFs(performance shaping factors) classification system. Based on them, two kinds of questionnaires for engine driver and train despatcher each were developed. Then Analytic Hierarchy Process (AHP) methodology was used to evaluate what factors were critical to human error.

The main purpose of this study is to develop air transportation cultural index which is able to estimate the level of them. Generally Speaking, air transportation cultural, a compound word of 'air transportation' and 'culture', is a substantial entity consisting knowledge, art, morality, legality, cultivation, customs, and etc, which comes from aircraft operation sector, airport operation/management sector and user sector. They are classified in a primary scope, as aircraft operation sector relating to flight operation, airport operation/management sector and user sector. The research and analysis were taken approximately 4 months, from June 2004 to October 2004. To evaluate the index, the detailed item for three categories were chosen and quantified. The grades for each items were induced from calculation formula for air transportation cultural index by applying weight values. The final grade of Korea's air transportation cultural index recorded 63.19 points.

Recently, due to the primary emphasis of environmental problem, the proper selection of the prevention technology systems necessary for Dioxin treatment has been one of the critical issues in the industrial sector. This paper shows how an Analytic Hierarchy Process(AHP) model can be used for assessing the performance of selected prevention technology systems: SDA/BF-SCR, SNCR-SDA/BF, SDA/BF, EP-WS-SCR, ED-WS, and EP-SCR-WS essential for Dioxin treatments. The final results show that SNCR-SDA/BF is the most attractive prevention technology system to use in an incinerator system, followed by SDA/BF-SCR, SDA/BF and EP-WS-SCR. This is consistent with the information that we found with respect to the elements that were taken into consideration. Sensitivity analysis is also provided here.
