Korea has increased R&D investment continuously for the improvement of global technological competencies. Korea ranked first in the world with 4.15 percent in the ratio of R&D investment to GDP. In particular, the private sector occupies a crucial position of technological innovations in Korea, constituting 78.5% of total R&D investment. However, quantitative growth strategy is no longer effective, so efforts to enhance efficiency by upgrading qualitative level are badly needed. This paper studied methods for improving firms' business performance. For this, it tried to empirically verify technology strategy and technology planning capability's influence factors on the improvement of business performance. The study showed that technology strategy and technology planning activities have positive effects on the improvement of business performance. And it was revealed that coordination flexibility contributes to the enhancement of business performance by positively controlling technology planning activities. The study performed sample survey on the companies with R&D centers and multiple regression analysis and quantile regression were used for the analysis.

The quality of early cost estimates is critical to the feasibility analysis and budget allocation decisions for public capital projects. Various researches have been attempted to develop cost prediction models in the early stage of a construction project. However, existing studies are limited on its applicability to actual projects because they focus primarily on a specific phase as well as utilize restricted information while the amount of information collectable differs from one another along with the project stages. This research aims to develop two-staged cost estimation model for the schematic planning and preliminary design process of a construction projects, considering the available information of each phase. In the schematic planning stage where outlined information of a project is only available, the Case-Based Reasoning model is used for easy and rapid elicitation of a project cost based on the extensive database of more than 90 actual highway construction projects. Then, the representing quantity-based model is proposed for the preliminary design stage where more information on the quantities and unit costs are collectable based on the alternative routes and cross-sections of a highway project. Real case studies are used to demonstrate and validate the benefits of the proposed approach. Through the two-stage cost estimation system, users are able to hold a timely prospect to presume the final cost within the budge such that feasibility study as well as budget allocation decisions are made on effectively and competitively.

Standards-curriculum based archival contents for education is the best effective teaching and learning units for historical thinking abilities. This paper purposes a developing procedures of an archival contents for education that is theoretical instructions of developing an archival contents for education by the National Archives of Korea. This paper can be used of the theoretical bases for the National Archives of Korea by proposing the methodology of development of an archival contents for education. The developing procedures of an archival contents for education is the same with the procedures of developing an e-learning contents that has planning, analyzing, designing, developing and assessing steps but it is characterized by an archival contents for education that is curriculum standards analysis, collection analysis, and detailed design for structured formats in effective-accomplishments for teaching-learning objectives. I propose the procedures for determining teaching-learning subjects that enable the development of an archival contents for education by curriculum standards analysis. I also propose the procedures for deriving the key words from the teaching-learning subjects. Collection analysis methods analyze key records that correspond to the learning subjects according to the selection criteria of primary sources. In the steps of designing, titles of contents and contents structures have to be determined and storyboards based on flowchart of learning have to be made of according to the results of analyses. In the steps of developing contents, making a copy of primary sources like a original is the key points. And also in the steps of assessment, products of teaching-learning contents to effectively achieve the teaching-learning objectives have to be estimated by the appraisal board. Finally I propose that user's survey research after the services have to be reflected on contents updates and new developments of contents.

코로나19 이후 건축사업계 비대면 작업 등의 필요성이 대두되면서, 스마트건설 플랫폼 기술인 BIM(Building Information Modeling, 건설정보모델링) 활성화에 관한 목소리도 높아지고 있다. 최근 한국건설기술연구원에서는 공공분야 BIM 기술의 성숙도를 4단계(레벨1~4)로 봤을 때, 우리나라의 평가치는 '레벨1' 초보 수준에 머물러 있다는 진단을 냈다. 이미 '레벨3' 수준에 진입한 영국 등 선진국보다 뒤처져 있다는 분석인데, 이는 2D 환경을 기반으로 설계 또는 시공업무에 대해 제한적으로 BIM을 적용하면서, 일정 규모 이상의 설계BIM만 의무화한 수준이기 때문이다. BIM 트렌드가 '기술개발'에서 '활용' 단계로 넘어가는 과정 가운데 건축분야에서의 활성화 방안은 무엇일까. 월간 '건축사'가 'WBIM(주.더블유빔)'사(社)의 이재환 대표를 만나 BIM의 현장 활용성, 그리고 적용 측면에서의 현실문제 등에 대한 현장 이야기를 들어봤다. 각종 개발사업과 설계파트를 지원하며 BIM전문가로 활동해 온 이재환 대표는 "기획단계부터 BIM을 활용하면 사업 진행 전 과정에서 실시간 검증이 가능하고 동시에 각종 아이디어를 효과적으로 적용할 수 있다"면서도 "활용성을 확보하려면 업계뿐 아니라 발주처, 감독 등도 BIM에 대한 이해도를 높여야 한다"고 말했다.

As the number of small households (1 to 2 persons per household) in Korea gradually increases, so does the importance of housing supply policies for small households. In response to the increase in small households, the government has been continuously supplying urban housing for these households. Since housing for small households is a sales and rental business similar to apartments and general business facilities, it is important for the building owner to calculate the project's estimated construction duration during the planning stage. Review of literature found a model for estimating the duration of construction of large-scale buildings but not for small-scale buildings such as urban housing for small households. Therefore this study aimed to develop and verify a model for estimating construction duration for urban housing at the planning stage based on multiple regression analysis. Independent variables inputted into the estimation model were building site area, building gross floor area, number of below ground floors, number of above ground floors, number of buildings, and location. The modified coefficient of determination (R_a²) of the model was 0.547. The developed model resulted in a Root Mean Square Error (RMSE) of 171.26 days and a Mean Absolute Percentage Error (MAPE) of 26.53%. The developed estimation model is expected to provide reliable construction duration calculations for small-scale urban residential buildings during the planning stage of a project.
