Recently, the breakdown of online banking servers and the leakage of customer information give rise to much concern about the security of information systems in financial and banking companies in Korea. The enforcement of security for information system becomes much more important issue than earlier. However, the security reinforcement of information system is restricted by a budget. In addition, the activities' cost to secure information system from threatening are under uncertain circumstances and should be established by a human decision maker who is basically uncertain and vague. Thus, making the budget for information system is exposed to any extent of the risk for these reasons. First, we introduce brief fuzzy set theory and fuzzy AHP (Analytic Hierarchy Process) methodology. Then, the cost elements that comprise yearly budget are presented and the priorities among the cost elements are calculated by fuzzy AHP. The cost elements that are exposed to risk are evaluated from the both perspectives of the risk impact and risk occurrence possibility which are expressed as linguistic terms. To get information on the risk profiles-pessimistic, most likely, and optimistic-for each cost element, the evaluation is accomplished and the result is presented. At last, the budget ranges-minimum, mode, maximum-for each cost element are estimated with the consideration of the risk profiles.

Cost estimating is essential in decision-making for conducting project management on early design stage. The cost estimating method for each stage varies according to level of design detail. Therefore, in the cost estimating method for each stage, it must distinguish quantity items that can be directly measured from quantity items that should be predicted. The parametric estimating method is able to support cost planning for various design attributes as it is possible to set impact factors related to design features as parameters. This study suggests a prediction method for quantity information that is required to estimate the final cost during the early design stage. The case study suggests an predicting method for the steel (rebar) ratio of office buildings. The suggested parametric cost estimating model enables users to predict the steel (rebar) quantity for various design alternatives according to design features. During quantity predictions, IG(Information gain) measurements for the design attributes were analyzed, by setting the ratio of steel-rebar quantity(Ratio: ton/Concrete_㎥) as the dependent variable.

Recent projects for transferring Public Office buildings and estimation of appropriate construction expense are highly important for both government and construction firms. Moreover, estimation and management of construction expense can be regarded as extremely important duties for effective execution of a national budget as nation’s finance is invested in the Public office building projects progressed by the government. To progress one project for Public office building, not only the organization demanding the project but also an investment screening organization, a budget-managing organization, a feasibility assessment institution and many other related organizations participate in the project and a lot of decisions arisen from the project operation are made on the basis of construction expenses calculated for relevant stages. And estimation of rational construction expense is also critical for designers in order to create design within the fixed budget simultaneously with securing the quality and efficiency of structures to the maximum. Therefore this research suggested an improvement process to analyze problems in current construction expense management process and to administer the construction expenses effectively.

Many companies have endeavored to build a quality cost management system in order to be more productive business organization. This study shows the detail procedures of constructing a quality cost management system which is believed to be appropriate for their business system. That is, the method to calculate the quality cost and the linking logic between the quality improvement and its financial impact are explained based on a particular industry case. In this sense, the changes of business performance measures such as market share, customer satisfaction, etc. were analyzed in the longitudinal perspective for the consecutive 4 years (2003~2006). As the quantitative results of this study, the improvement activities based on the quality cost management system resulted in the 32% reduction of quality cost and the 121% increase of business profit, compared 2005 with 2006. In the qualitative perspective, the successive practice of quality cost reduction and the job information sharing in business unit were obtained by providing the best practices and bench-marking cases. Finally, the customer satisfaction has increased so that the customer-friendly management system has been accomplished. With these efforts, the 3.4% increase of the market share and the 3% increase of the customer satisfaction were obtained in 2005. As the future study, the current study can be extended to the concept of COPQ (cost of poor quality) which focuses on the hidden quality cost of the whole business activities. Such extension of analysis will help us understand the wider role of a quality cost management system in the business.

본 연구는 겨울철과 여름철에 답리작 사료작물의 랩사일리지 생산에서 연구보고된 조사료재배품종과 재배방법을 기준으로 하였을 때, 소요 기계에 따른 기계화 생산 작업의 특성과부담면적, 기계 이용비용을 분석하여 조사료생산비용을 산출하였다. 생산비용은 작물종류(호밀, 청보리, IRG, 수단그라스), 파종방법 (산파, 조파)과 트랙터 마력 (50, 75, 100, 130 ps)에따른 경작규모별 (부담면적 ha별), 부담면적대비경작지비율별 (25, 50, 75, 100%), 작부체계별(품종 숙기별, 동․하계 작물별)로 분류하여 산출하였다. 트랙터 100 ps, 조파를 기준으로 단일 품종 재배보다 호밀, IRG와 청보리 등을 품종 숙기별로 재배할 때 파종은 20일에서 30일로, 수확은 약 30일에서 40일로 시기가 늘어나기 때문에 부담면적이 57.1 ha에서 77.5 ha로 증가하였다. 동․하계 작물 연중 재배시 생산비용은 100 ps 트랙터, 조파, kg-TDN 기준으로호밀 + 수단은 250원, 청보리 + 수단은 215원,IRG + 수단은 234원, 호밀 + 청보리 + IRG+ 수단은 233원으로 나타났다. 이는 연중 재배하지않는 경우에 비해 고정비가 줄어들기 때문에생산비용은 약 30~50% 절감되었다. 따라서 답리작 사료작물의 랩사일리지 생산시 노동피크와 수확시기의 분산, 기계장비의 효율성을 제고할 수 있도록 품종 숙기별 연중 재배 작부체계의 이용이 바람직한 것으로 판단되었다.

The purpose of this study was to understand interrelationships among switching costs, customer satisfaction, and switching intent in a family restaurant. Based on a total of 427 customers obtained from empirical research, this study reviewed the reliability and fitness of the research model and verified a total of five hypotheses using the Amos program. The hypothesized relationships in the model were tested simultaneously by using a structural equation model (SEM). The proposed model provided an adequate fit to the data, χ2=137.881 (df=50); p〈 .001; CMIN/df 2.758; GFI= .947; AGFI= .919, NFI= .965; IFI= .978; TLI= .970; CFI= .978; RMR= .047; RMSEA= .064. The results showed that switching cost (β= .123) in a family restaurant had a positive (+) influence upon customer satisfaction. Further, switching cost had a significantly negative (-) effect on switching intent (β= -.414). In addition, there were moderating effects related to customer knowledge and variety seeking orientation in terms of the causal relationships between switching costs, customer satisfaction, and switching intent. Limitations and future research directions are also discussed.

In order to meet the national standard and public needs for Seoul Metro subway, air purification has been taken into a consistent consideration with the addition of high quality control facilities. This work focuses on the review of the cost effectiveness to improve the air filtration of an MVAC (mechanical ventilation & air conditioning) in a field subway. The inflow PM₁₀ and PM_2.5 into the test MVAC chamber were 19.4 kg/yr and 8.9 kg/yr respectively. It corresponds to the environmental cost of 5,857,000 won for PM₁₀ and 6,608,000 won for PM_2.5 every year. While the current filtration system collects approximately 55% of the inlet PM₁₀ and 35% of PM_2.5, a new lay-out showed 80% for PM₁₀ and 55% for PM_2.5. The new design presented the environmental benefit for PM10 with 1,464,000 won, whilst the additional cost required 3,192,744 won. In the future, however, the increase of environmental benefits for the indoor dust over the atmospheric aerosols will more or less compensate the potential cost.

Unit cost for asbestos removal work which have been made out at government contract award for recent three years has been reviewed and shown with table. And the cost have been compared with ones made out by two agencies, American asbestos removal specialists, government ministry for making out comparison tables. First, legal and practical work status survey have been made to determine reasonability of introducing separate contract-awarding system, as a part of ensuring reasonable unit work cost. And then, two different status have been compared and there in introduction possibility of separate contract-awarding system, it is found out. In interior removal work case, it is thought that 50% by owner, 60% unit work cost by the expert of which removal specialist think as reasonable unit cost. the results for exterior and spray work method are shown with almost same context. Impact factors for determining unit work cost such as project mount, project kind, contract-awarding method, subcontract method have been compared with parties. Removal specialist and expert group have almost same ideas for project amount which has been hightestly weighed but owner's recognition has partially lower than specialists idea. There are almost no difference of recognition between three(3) parties for project kind. Idea comparison of reasonable unit work cost for asbestos removal work between three concerned parties has been analyzed and found out that expert group do unit work cost, 65% of which removal specialists estimate, in interior tex removal. And there is almost no difference between them in exterior roof slate removal. But there is considerable difference between them that owner estimates 50% unit cost of specialist one while expert group estimate 50% of specialist idea of unit removal cost.
