이동망 착신독점력 규제를 위해 각국 규제당국은 이동망 착신접속료(Mobile Termination Rate: MTR)를 원가기준으로 규제하고 있다. 원가기준으로는 과거 FDC 방식이 채택되어 왔으나 2002년 영국이 "LRIC+" 방식으로 MTR을 결정한 이래 "LRIC+" 방식이 EU를 비롯한 OECD 주요국의 MTR 산정방식으로 보편화되어 왔다. 그러나 2009년 EU에서 순수증분비용(Pure Long Run Incremental Cost) 방식으로 착신접속료 규제방식 변경을 권고하는 권고안을 채택함으로써 EU 가맹국은 Pure LRIC 방식으로 MTR을 변경하여야 한다. 본 고에서는 Pure LRIC 방식 채택을 권하는 EU 권고안 채택 배경, Pure LRIC 산정 방법론, EU 권고안에 대한 각국의 이행계획을 살펴보며, Pure LRIC 채택이 가져올 영향을 살펴보고자 한다.

A LLU system is developed for efficient use of existing local loop. By this system, new entrant ran use the local loop indifferently comparing with incumbent telecommunications operator. To implement the LLU, bottom-up typed LRIC model by network redesigning was accepted for costing system in Korea. In this paper, local loop redesigning methodology is presented to build a bottom-up typed LRIC model.

The latest parceling-out price upper limit ancestor memorial service enforcement, Sale in lots circle is elated interest of society each floor for construction working expenses by open etc. but private investment law for society basis facilities, because circle that is presenting in parceling-out price upper limit ancestor memorial service back is different system (configuration item), cross is expected. A lot of study results connected with cost control expense arbor in the mountains etc. were presented until present, but persistent DB expulsion prohibition. Cost information is standardization unpreparedness of system. It is real condition that is hoarded since research and development by practical use plan presentation unpreparedness etc. Therefore, in this study, desire does actual date use plan presentation by purpose through DB construction after process by information form of good quality so that can collects efficiently and manages and utilizes at construction production step flag firm' s results data which is achieved. Can utilize to data of tool development that maximize ultimately comprehension about employer' s business and business order ability through persuasion, and diverts in cost control business hereafter.

The current enforcement regulation of "Construction Technology Management Act" prescribes calculation standard of environmental preservation cost in construction site. According to this standard, environmental preservation cost is calculated by using the quantity-per-unit costing method or applied fixed rate on direct cost. However, when calculated by using the quantity-per-unit costing method it is few items to put in the budget according to standard of construction estimate and in the case of using the fixed rate on direct cost it is not considering various characteristics of the construction site. Therefore, it is needed a improvement plan of estimating method and management system for environmental preservation cost. In this study, it surveyed the actual state of the environmental preservation cost according to magnitude of project, site location, anti-pollution facilities and etc. over 38 road projects. The research reported in this paper environmental preservation cost was variously distributed over construction sites. Thus it needs to estimating method and management system to consider characteristics of construction site for environmental preservation cost.

The development of the Construction Production Rates System for appropriate construction cost calculation has recently come to the fore as a means of invigorating OSC based PC structure which currently needs institutional frameworks. PC structure based construction expenses consist of the factory-built assembly, transportation and on-site installation. Recently, in the field of transportation and site installation, research on product structure development is being conducted, such as presenting the standard product calculation system reflecting the results of field survey for each subsidiary materials (Lee et al., 2021). On the other hand, there is no ongoing research on estimating construction expenses of Factory-built assembly. This study suggests Construction Production Rates System which can be used for PC subsidiary materials based Factory-built assembly cost estimations. For the research, work types for the construction procedures have been categorized, and the standard input manpower suitable for the corresponding work characteristics has been derived from analyzing the associated Construction Standard Production Rates for each work type. Also, as the research referred PC subsidiary materials (such as columns, beams, walls, and slab, as well as on-site installation) and the standard number of workforce based on work types, one can calculate direct labor cost, using what the research shows. In addition, it suggests that the size of individual subsidiary materials be the extra cost factor, by using the characteristics that productivity changes depending on the size(m³) of subsidiary materials. It is expected that the research can contribute to objectively verifying factory-built assembly cost through of PC structure, which currently relies on estimates.

Companies of Build-to-Order(BTO) strive to achieve customer responsiveness and cost efficiency simultaneously. The success of BTO depends upon the high volume production based on product plat form and delayed differentiation principle on the one hand, and upon the rapid estimation of delivery and cost for the customer orders on the other hand. Expeditious processing of a specific order requires the rearrangement of production resources and the schedule, which results in increased cost. This paper describes a cost estimation method using activity-based costing depending on the schedule change caused by urgent customer orders.

1998년 European Commission에서 권고한 이래 LRIC 모형은 미국 및 유럽 각국의 규제기관 (National Regulatory Authorities ; NRA)에서 상호접속규제를 시행하는데 사용되는 주요 수단이다. 2004년 영국의 이동전화 착신서비스에 대한 보고서에서 영국의 Ofcom은 LRIC를 2G방식의 이동전화 착신서비스 제공에 따른 원가산정 방법으로 채택하고 있다. 그러나 기존 2G 사업자들이 3G시장에 참여함에 따라 2G 음성통화가 3G로의 전이가능성이 제기되어 3G 서비스제공에 따른 2G 접속료 시장의 충격을 완화하고자 LRIC모형에 3G서비스를 추가하게 되었다. 이동망 원가모형의 기본 구조는 크게 다음과 같은 4개의 모듈로 구성되는데, 이중에서 사업 자간 문제제기가 많고 이견이 많았던 Network모듈과 이동망 모형의 선행모듈인 Input 모듈에서 제기된 이슈사향을 살펴보고, 국내 이동망 LRIC 모듈 개발시의 시사점을 도출하고자 한다.

The cost accounting of products on energy system is important for evaluating the economical efficiency and deciding the reasonable sale price. In the present, the suggested OECOPC method was applied to a combined cycle cogeneration, and each unit cost of electricity and heat products was calculated. In addition, the previous thermoeconomic methods were applied and calculated to equal system. As a result of comparing various methods, the unit costs by OECOPC method were calculated in the middle value of those. This result tells that OECOPC methods are most moderate. The suggested OECOPC method can apply any energy system. Hence this method is expected to make contribution to cost accounting on energy System.
