According to the Global Wind Report of the Global Wind Energy Council (GWEC) in 2017, global wind power electricity generation capacity has been dramatically developing from 23,900 MW in 2001 to 486,790 MW in 2016. However, wind power generation in South Korea accounts for only 0.2 % of total power generation. Nonetheless, electricity production by wind power generation is soon expected to reach the grid parity where the cost of generating electricity by wind power is equal to the cost of fossil fuels such as oil. In this study, we analyzed the criteria of vessel traffic and fishing activities of major offshore wind farms in Europe where 88 % of the offshore wind power facilities are located. Finally, we suggest critical considerations based on the analysis.

This paper addresses methodology in order to consider CHP (Combined Heat and Power) capacity in the Basic Plan of Long Term Electricity Supply & Demand and presents effects on it. The method performs state in extent that do not change maximum in the Basic Plan of Long Term Electricity Supply & Demand. For analysis that occurs some advantage this method compares with Basic Plan of Long Term Electricity Supply & Demand. It includes EES (Expected Energy Served), Fuel consumption, amount of $CO_{2}$ emission reduction.

The New Excellent Technology (NET) designation system, introduced in 1989 for the purpose of promoting the development of domestic construction technology and enhancing national competitiveness, reviews the statement of construction cost of new technologies. And the cost reduction effect such as design, construction, and maintenance cost and the effect of reducing the construction duration are evaluated as an evaluation criteria of economic feasibility. However, in this evaluation process, differences of opinion between the institution of construction cost estimating standard management and the new technology developer about unique technologies frequently occur. In addition it is difficult to objectively compare the construction duration with existing similar technologies because there is no information on productivity as the current cost estimating standards for new technologies only present the required amount per unit quantity. In this study, the current state of cost estimating criteria review procedure, evaluation criteria, and cost estimating standards establishment method were analyzed when screening for the designation of a new construction technologies, and compared with overseas cost estimating standards, measures to improve the cost estimating standards of current construction new technologies were suggested. Through the improved cost estimating standards of this study, it is expected that cost information on new technologies will be provided to clients in more detail than the current ones, and the availability and applicability of new construction technologies would be improved by simplifying the construction cost calculation process more.

When various kinds of outputs are produced from a single energy system, the methodology which allocates the common cost to each output cost is very important because it is directly related with the profit and loss of producers and purchasers. In the cost allocation methodology of the heat and the electricity on a cogeneration, there are energy method, work method, proportional method, benefit distribution method, various exergetic methods, and so on. On the other hand, we have proposed a worth evaluation method which can be applied to any system. The definition of this methodology is that the unit cost of a product is proportion to the worth. Where, worth is a certain evaluating basis that can equalize the worth of products. In this study, we applied this methodology to a gas-turbine cogeneration which produces 119.2 GJ/h of electricity and 134.7 GJ/h of heat, and then we allocated 3,150 $/h of fuel cost to electricity cost and heat cost. Also, we compared with various cost allocation methods. As the result, we conclude that exergy of various kinds of worth basis evaluates the worth of heat and electricity most reasonably on this system.

Also, we compared with various cost allocation methods. As the result, we conclude that reversible work of various kinds of worth basis evaluates the worth of heat and electricity most reasonably.

국내 알코올공업은 주류공업의 발전으로 요약할 수 있다. 특히 주정공업의 발전은 농업정책과 국민보건 차원에서 원료의 배정, 공동 주정판매 및 가격 고시제 등 제한적인 규제 하에서도 괄목할 만한 성장을 거듭해 왔다. 내년부터주정수입 및 시장이 완전 자율화됨으로서 무한경쟁시대를 앞두고 있다. 경쟁력 우위를 확보하기 위해서는 주질 향상과 더불어 생산원가 절감이 필수적이다. (중략)

오늘날의 생산, 가공기술을 공장자동화(FA: Factory Automation) 기술과 첨단 가공기술 두 방향으로 양극화 되어 나갈 것으로 보인다. 현재 각 기업에서 부분적으로 실시하고 있는 목 표원가관리 시스템도 그 실효를 거둘수 있기 위해서는 현업에서 실질적으로 관리할 수 있는 인 자를 지니고 있어야 한다. 이러한 인자로서 특히 공작기계 공업에서와 같이 다품종 소량생산 체제하에서는 부분별 개별원가 계산제를 들수 있고, 새로운 생산 시스템(FMS 등)과 기종의 전 문화에 맞는 직접원가제도가 유효하다. 이러한 기본인자를 쉽게 인식할 수 있는 것은 앞으로도 전산화가 이루워지지 않고는 생각할 수 없다는 점이다. 앞으로의 공작기계의 방향이 FMS를 전제로한 CNC 및 전용화 추세에 맞는 관리 시스템은 필연적으로 단순화를 요하고 그를 위한 전산소프트웨어의 개발이 시급하다.
