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.

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 current standard cost for recycling applied under the Extended Producer Responsibility(EPR) institution, is not coping with continuously increased number of obligatory subject items as well as a variety of variable cost changing factors regarding the recycling treatment cost caused by price fluctuation such as increased material and labor cost entirely across the society; changes in recycling treatment process following the developing technologies; and changes in the required work forces and equipments followed by the trends of automated facilities. Despite such various cost fluctuation factors, the current EPR is not coping with the trends, making the re-calculation process difficult, which causes differences between the real treatment cost for recycling. In this study, the analysis was made on main factors affecting on the related cost and the related price changing index was calculated, by conducting the influence evaluation on the standard cost factors of the current standard cost for recycling. Through theses results, more objective standard will be set for the re-calculation of standard cost for recycling to greatly contribute to setting up the midterm and long-term strategies in the future towards efficient institution.

The commission assessment and cost analysis of a measuring rate system of food waste were performed to account a total budget. The selling price of tax clearance was between about 240 wons and 270 wons, a vinyl bag was sold at from about 260 wons to 290 wons, based on a vessel size of 5L. After one year the measured rate system was enforced, the total cost for buying vessels in the Daejeon metropolitan city area was accounted about 720 million wons. Purchasing cost of bar code tax clearance and vinyl bags were decreased to 215 million wons due to the reduction rate, while the selling cost was increased to 328 million wons, compared with the existing cost. Therefore, the total saving cost was 2,639 million wons per year in the city.

본 연구에서는 국내 LTPP 구간에서 수행된 FWD 시험의 결과를 바탕으로 섬유보강, 폴리머 개질, 일반 아스팔트 포장의 구조적 성능을 비교 평가하였다. FWD 시험 결과, 표층 하단부의 인장변형량이 섬유보강 아스팔트는 29%, 폴리머 개질 아스팔트는 21% 저감되는 것을 확인하였다. 또한 FWD 처짐량을 역산하여 각 층의 탄성계수를 추정한 후 이를 바탕으로 AASHTO 설계방법, 구조적 해석 방법 및 생애주기비용분석을 통해 섬유보강 및 폴리머 개질 아스팔트 포장의 비용 효과를 분석하였다. 분석 결과, 섬유보강은 약 5cm, 폴리머 개질은 약 3cm의 아스팔트 층 두께 감소 효과를 보여주었다. 그러나 섬유보강 및 폴리머 개질 아스팔트의 고가격으로 인하여 전체 시공재료비는 일반 아스팔트 포장에 비해 상승하는 결과를 보여주었다. 생애주기비용 결과는 초기 공사비는 섬유보강 및 폴리머 개질 아스팔트 포장이 높지만, 유지관리비용 및 사용자비용은 감소하는 것으로 나타났다.

This study was carried out to evaluate the Life Cycle Cost(LCC) of four types of BIPV(Building Integrated Photovoltaic) systems -Glass plus Granite, Crystalline BIPV, Crystalline BIPV + Glass plus Granite and See through Amorphous BIPV -which were vertically installed to generate the same capacity(2kW) and the same area. Initial investment costs, cost savings and maintenance costs had been predicted during the period of analysing the LCC of four types of BIPV(Building Integrated Photovoltaic) systems installed for the purpose of evaluating the LCC. In case of cost savings, it had been analyzed by measuring the amount of electric power generated, reduction in lighting load and heat & cooling loads through simulation. From this analysis, it was predicted that the See-through amorphous BIPV offering cost saving advantages demonstrated the economical efficiency similar to the Glass plus Granite when it is backed by more than 20 years of durability.

This study was conducted to evaluate the menu of a Japanese restaurant in a first class tourism hotel. The calculations used for the menu analysis were conducted using MS Excel 2003. Several previous studies have been conducted to analyze menus. For example, Pavesic used of the weighted contribution margins (WCM) and potential food cost (PFC%) to evaluate menus, while Kasavana & Smith used the mix margin (MM%) and unit contribution margin (CM) to evaluate menus. The menu engineering method focused on the customer's viewpoints, while the Cost/Margin analysis method considered the manager's viewpoints. The menus that need continuous keeping Kasavana & Smith (Star) and Pavesic (Standard) included 'Assorted sashimi with side dishes (big), 'Lunch box special', 'Tempura course', 'Broiled Spanish mackerel and side dishes', 'Shrimp tempura', 'Special sushi', 'Seafood Udong', 'Buckwheat noodles'. The results of this study should increase customer satisfaction and profits at the Japanese Restaurant.
