최근까지도 양자 하드웨어의 개발은 꾸준히 이루어졌지만, 개발 수준이 양자 소프트웨어의 연구에 사용하기에 부족한 정도이다. 따라서 양자 하드웨어 없이도 양자 소프트웨어의 연구를 진행하기 위해서는 양자 시뮬레이터와 컴파일러가 필요해졌다. 이에 다양한 양자 시뮬레이터와 컴파일러가 제공되었으며 양자 시뮬레이터와 컴파일러가 하나의 소프트웨어 프레임워크를 이루고 있는 풀-스택 라이브러리 역시 다양하게 제공되고 있다. ProjectQ는 풀-스택 라이브러리 중 하나로써 Python을 기반으로 하여 무료로 사용 가능할 뿐만 아니라 문법이 쉬워 접근성이 높다는 장점이 있고, 컴파일러에 시뮬레이터와 에뮬레이터의 효율적인 적용이 가능하여 새로운 양자 알고리즘 개발의 가속화나 양자 회로의 시각화 등이 가능하다. 따라서 본 논문은 ProjectQ의 내부 구성과 기능을 구체적으로 설명한 후, 기존의 Carry-Sum adder를 응용한 새로운 양자 회로를 직접 구현해보았다.

The purpose of this study is to review all phases of the pilot project through the implementation of the Green Remodeling process. The Green Remodeling process was developed to facilitate anyone's ease of use. The Green Remodeling process consists of five phases : project, plan, design, construction, operation and maintenance. Each stage simulation was performed and the energy saving was predicted. Architects can easily obtain energy information of a building. In this study, we propose a green remodeling proposal plan through pilot project. Ultimately, the spread of green remodeling will greatly contribute to achieving the goal of reducing greenhouse gas emissions.

The purpose of this study is to objectively grasp the effect of the engineering education innovation support project among the national engineering-related financial support projects by dividing the groups according to the participation of support projects from 2018 to 2020 and dividing the university performance. As a result of the research the engineering education innovation support project has been consistently producing excellent results of field-based engineering education such as field-oriented industrial-educational collaboration capstone design, technology commercialization, and development and operation of corporate-linked education. It was found that the results showed that the dropout rate of college were lowered. In the future, it needs to be prepared as a place for new and free trials, innovations, and opportunities so that the engineering education innovation support projects can become the mother of other business groups.

While many studies on feasibility analysis for housing projects have been released, the main focus was on economic feasibility and factors related to developers were not clearly identified enough to be used in practice. In order to establish a feasibility analysis model for apartment development projects requested by developers in Korea, 31 driving factors behind projects' success were identified under seven different categories. Criterions of the each factor were also developed, and weight of each factor was assigned by applying the Analytical Hierarchy Process(AHP). Finally, based on the Monte Carlo simulation, the feasibility analysis model was established, providing probability distribution of project's grade. The model was applied to 12 housing projects to verify its reliability, and found that the model properly filtered projects that are unlikely to be profitable, indicating reasonable reliability of the model. The model can be a useful tool for contractors, especially with less experience in analyzing project development feasibility.

Since the 1980s, Build-Operate-Transfer and its variations have become a common approach to develop large-scale infrastructure projects. Despite the slight variations in contractual settings, the key issue for all parties concerned is to assess the risks and uncertainties inherent in a project. The risk factors studied and highlighted by past researchers are very diverse. This paper starts with an objective to compare the risk factors in different sectors of infrastructure, and then categorize them into two kinds: general and specific. Following this classification, risk mitigation strategies should be adopted differently at the corporate and project levels. A few short cases have also been used to illustrate the flexible measures or "options" that some project participants have designed to address risks and uncertainties at the two levels.

Building Information Modeling (BIM) is an effective decision-making platform that helps to save project cost and enhance quality of construction. By generating and linking a wide variety of objects data, BIM can be effectively utilized, and it should be ensured that object properties maintain consistency throughout the project period of design, estimates, construction, maintenance and repair. This study examined how to utilize BIM data in a construction project, by linking cost and schedule data in web environment, to better utilize the information and maintain consistency of the BIM information. To do so, the model integrated WBS data and CBS data, linked them with BIM model to realize 5D simulation in web environment. As a result, cost and schedule data could be simultaneously acquired, and object properties-cost, schedule, location-as well. These are expected to contribute to developing a BIM-based automatic data-processing system in web environment.

BIM is a practical and economical technology used in the construction process. Despite the fact that BIM is widely used in the design and another stage before construction, it is not largely applied during the construction stage itself. However, it is important to opt for BIM during construction stage because there may occur a number of risks such as construction delay and increased construction costs. Therefore, the present paper contains the analysis of the model use, which is mainly applied to respond to the BMI RFI that represents an information requirement of construction site workers, by analysing the BMI RFI application at the construction site. In addition, there is an analysis of the way the derived model use affects the project goal aimed at the project success.

건설 프로젝트에서 설계시공 일괄방식은 프로젝트에 참가하는 모든 참여자가 협력하기 때문에 일관성, 공기단축, 품질향상, 프로젝트 요구를 만족시키는 설계의 혁신과 같은 효과를 기대할 수 있는 발주방식이다. 서구에서 일괄방식은 우수한 발주방식을 찾고자 하는 노력의 결과로 보고 있으며, 성과분석 결과 공기단축, 비용절감, 품질향상 등이 분리방식에 비하여 우수한 것으로 입증되어 발주가 확대되고 있다. 일괄방식은 1975년 국내에 도입되어 9000년까지 공공부문 전체 프로젝트의 10% 이하에만 적용되었으나, 이후부터 지속적으로 증가하여 2005년에는 26%까지 그 적용이 증가하였다. 이에 본 연구에서는 건설통계분석, 발주방식 성과분석, 설문조사를 바탕으로 시스템 다이내믹스 인과지도를 작성하여 그 원인을 분석하고 서구에서와 같이 우수한 발주방식으로 정착되기 위한 정책적 개선방안을 제시하고자 한다.

With the development of 3D-based CAD (Computer Aided Design), attempts at freeform building design have expanded to small and medium-sized buildings in Korea. However, a standardized system for continuous utilization of shape data and BIM conversion process implemented with 3D-based NURBS is still immature. Without accurate review and management throughout the Freeform building project, interference between members occurs and the cost of the project increases. This is very detrimental to the project. To solve this problem, we proposed a continuous utilization process of 3D shape information based on BIM parameters. Our process includes algorithms such as Auto Split, Panel Optimization, Excel extraction based on shape information, BIM modeling through Adaptive Component, and BIM model utilization method using ID Code. The optimal cutting reference point was calculated and the optimal material specification was derived using the Panel Optimization algorithm. With the Adaptive Component design methodology, a BIM model conforming to the standard cross-section details and specifications was uniformly established. The automatic BIM conversion algorithm of shape data through Excel extraction created a BIM model without omission of data based on the optimized panel cutting reference point and cutting line. Finally, we analyzed how to use the BIM model built for automatic conversion. As a result of the analysis, in addition to the BIM utilization plan in the general construction stage such as visualization, interference review, quantity calculation, and construction simulation, an individual management plan for the unit panel was derived through ID data input. This study suggested an improvement process by linking the existing research on atypical panel optimization and the study of parameter-based BIM information management method. And it showed that it can solve the problems of existing Freeform building project.
