As software development and maintenance cost increase quickly, information systems managers are more concerned about how to effectively manage software cost. To estimate the software development cost, most public institutes of Korea use the software cost estimation standard established by the government. Unfortunately, the accuracy of the estimation derived from the standard has not been satisfactory in spite of repetitive modifications made to improve it. One of the major reasons for the inaccuracy is that the standard has too small a number of cost adjustment factors to reflect the various characteristics of a software development project. To remedy this problem, we propose new cost adjustment factors which can be incorporated into the standard and are important to enhance the estimation accuracy, based on the analysis of several well-known software estimation models. Furthermore, by applying the proposed model to real world software projects, we show that the proposed model can produce more accurate estimates than the current standard.

지금까지 이러닝 콘텐츠 개발의 대가 기준은 실제 이러닝 산업의 특성을 반영하지 않은 채 기존의 유사한 산업의 산정표나 가이드라인에 따라 산정되어 왔다. IT와 교육이 융합된 이러닝 산업에서 콘텐츠 개발 대가 기준의 부재는 이러닝 산업을 이끌어 가는 기업들에게 큰 애로사항으로 인식되어 왔다. 이러닝 산업의 특성을 반영하지 못한 개발 대가의 산정은 콘텐츠의 품질에 큰 영향을 끼치고 있으며, 이는 이러닝 산업의 성장과 발전을 저해하는 요인이다. 이러한 문제를 해결하기 위해, 본 연구에서는 이러닝 산업의 특성을 고려한 이러닝 콘텐츠 개발에 적합한 대가 기준을 제시하였다. 본문에서는 이러닝 산업의 콘텐츠 개발 대가 기준 책정에 대한 문제점과 그 특성을 분석하고, 기존의 대가 기준 산정 방식을 응용하여 이러닝 산업을 위한 콘텐츠 개발 대가 기준을 분류하고 정의하였다. 발주기관의 설문조사를 통해 이러닝 산업의 특성을 반영한 개발 대가 기준의 산정과 콘텐츠 개발 대가 기준 산정에 필요한 연구 방법론을 제시하여 이러닝 산업의 발전과 콘텐츠의 품질 향상에 기여할 수 있는 정책을 마련하고, 실질적으로 반영하여 사용함으로써 이러닝 산업이 보다 발전할 수 있을 것으로 기대한다.

The existing standard cost of project management of empowerment sector in general rural development project has problems with standard cost system without considering characteristics of empowerment project and unclear division of works. These problems are a lot of trouble to fulfill the project. Thus, it needs an arrangement of standard cost considering detailed characteristics of project management in the empowerment sector. The contents and results of this study can be summarized as follows. 1) To set accurate standard cost, we carried out three-step processes, such as elicitation of standard works, calculation of workload and determination of standard cost. (1) In an investigation of 30 rural area dividing 8 parts about an workload of empowerment project, an average workload is 1,499 hours. (2) Based on this results, the standard cost is calculated at 15% of project cost in over 600 million won, at 28.75% of project cost in under 500 million won, by standards of empowerment project cost. 2) It set the responsibility management cost to 15% of empowerment project cost considering existing awareness, workload and work professionalism of project management. Based on the results, It suggested the practical use as basis for efficient management of the future empowerment projects. To achieve this, It needs to promote maximizing results on the whole project through the legalization processes including amendment of existing regulations.

최근 정부는 이러닝 콘텐츠 개발의 대가 기준에 대한 조사를 기반으로 명확한 대가 기준을 수립하고 이러닝 산업의 특성을 반영한 이러닝 콘텐츠 개발 대가 산정 가이드라인(기준)을 공개하였다. 그러나 제도적인 뒷받침이 없으면 제도가 취지와 목적을 달성하지 못하고 사문서화될 소지를 안고 있어 정책적 기반 마련이 필요하다 이에 본 연구는 대가기준 활용 활성화를 위해 이론적 배경 정리와 분석을 통해 대가기준의 단계적 적용 활성화, 대가기준의 제정 고시 및 정기적 조정, 대가기준운영위원회 운영, 이러닝산업 실태조사와의 연계성, 저작권 공동 소유 문화 확산, 개발과정의 체계적인 모니터링, 대가기준 적용 활성화 정책 연구, 표준계약서와 연동을 통한 정책 실효성 제고 등의 정책을 제언하게 되었다.

Recently, the need for smart construction technologies related to the Fourth Industrial Revolution has been increasing in order to improve productivity of the construction industry. The Ministry of Land, Infrastructure and Transport has established Smart construction technology road map to commercialize the smart construction, and research and development is also underway. However, due to the lack of cost estimation standards for such smart construction technologies to be deployed to actual sites, smart construction technologies are not actively applied to construction sites. In particular, cost estimation standards are needed for construction machinery equipment with ICT technology that is currently available for commercialization. Therefore, as a preliminary study for the development of smart construction cost estimation standards, a case study was conducted on ICT construction estimation standards in Japan and present them as basic data for standards in Korea.

최근, OSC(Off-Site Construction)기반 PC구조의 활성화를 위한 제도적 기반 마련의 일환으로 적정공사비 산정에 필요한 품셈 개발을 요구받고 있다. PC공법의 공사비는 공장제작-운반-현장설치의 단계로 구성된다. 최근 운반과 현장 설치는 부재(subsidiary materials)별 현장실태 조사 결과를 반영한 표준품셈 체계(standard product calculation system)를 제시하는 등 관련 연구가 진행되고 있다(Lee et al., 2021). 반면, 공장 제작 공사비 산정과 관련된 연구는 전무한 실정이다. 본 연구에서는 PC 공법의 공장제작 공사비 산정기준 마련을 위해 공장 제작 환경에 활용할 수 있는 품셈 체계를 제시하였다. 이를 위해 시공절차에 따른 작업 공종을 도출하였으며, 공종별로 연계된 표준품셈을 분석하여 작업 특성에 적합한 표준 투입인력을 산출하였다. 품셈 체계는 PC부재의 현장설치와 동일하게 기둥, 보, 벽체, 슬래브 부재로 구성하였으며, 공종별 기능공을 기준으로 부재별 기본공수를 제시함으로서 직접노무비의 산출이 가능하도록 하였다. 또한, 개별 부재의 규격(m³)에 따라 생산성이 변화되는 특성을 고려하여 부재 크기를 품의 할증 요소로 제시하였다. 본 연구결과는 현재 견적에 의해 재료비료 계상되는 PC공법의 공장제작 비용을 객관적으로 검증할 수 토대 마련에 기여할 수 것이다.

The reference guide for the cost of establishing the digital documents has been used as a basis for establishing the budget for the construction of the knowledge information resource. However, due to the abolition of the nominal unit price notification in terms of IT projects, it is necessary to conduct research to convert the standard of the current labor force grade standard to the national incompetency standard (NCS). In this study, we investigate and revise the system and contents of the current knowledge information cost estimation model. In specific, i) we conducted gap analysis of cost estimation model and existing NCS model. As the contents conforming for the construction of the knowledge information resource were not adoptable, we define the description of the construction of the knowledge information resource and to identify the core elements of NCS prior to the improvement of the cost model. ⅱ) then we proposed improve the cost model considering integration with newly proposed NCS model for knowledge information construction job. In order to ensure the validity of the application of NCS development and cost estimation model, the experts reviewed relevant contents and made plans for improvement by using experts from supply and demand groups of various fields of national knowledge informatization projects.

In this study, we have developed a calculation system for BIM-based quantities, 4D process, and 5D construction costs, by integrating object shape attributes and the standard classification system which consist of Cost Breakdown System(CBS), Object Breakdown System(OBS) and Work Breakdown System(WBS) in order to use for the 4 dimensional process control of roads and rivers. First, a new BIM library database connected with the BIM library shape objects was built according to the CBS/OBS/WBS standard classification system of the civil engineering field, and a integrated database system of BIM-based quantities, process(4D), and construction costs(5D) for roads and rivers was constructed. Nextly, the process classification system and the cost classification system were automatically disassembled to the BIM objects consisting of the Revit-family style elements. Finally, we added functions for automatically generating four dimensional activities and generating a automatic cost statement according to the combination of WBS and CBS classification system The ultimate goal of this study was to extend the integrated quantities, process(4D), and construction costs(5D) system for new roads and rivers, enabling the integrated use of process(4D) and construction costs(5D) in the design and construction stage, based on the tasks described above.

It is an important issue in cost management to contract with the standard of cost estimate by the reasonable way in public construction projects. For the standard of cost estimate based on the Standard Estimating System, there is a difference of labor inputs between Standard Estimating System and actual quantities in construction projects. The duration of form work in multi-family housing depends on the manpower compared with other work, which is the critical path on the schedule management to be decided quality, and is the important to the cost management of construction projects. This study presented a simulation model of the productivity analysis for selecting the standard work type of form work in Multi-family housing construction projects.
