도로 건설현장의 디지털트윈 구현을 위한 디지털 건설정보구조에 관한 연구
정태원,지현욱,복진훈 한국ITS학회 2024 한국ITS학회논문지 Vol.23 No.1
스마트건설을 위한 업무의 디지털화는 상호 간의 디지털데이터를 원활하게 교류할 수 있어 야 효과가 있으나, 디지털데이터의 표준화 및 활용방안이 부족하다. 본 연구는 도로 건설현장 의 정보를 효과적으로 디지털로 변환할 수 있는 디지털 건설정보구조를 제안한다. 연구대상은 도로건설업무에서 중요도가 높은 작업계획, 일정관리, 안전관리, 품질관리이다. 건설정보구조 의 핵심은 건설정보를 객체와 작업으로 분리하고, 이 두 정보의 결합으로 단위업무를 정의함 으로써 건설정보의 표현 및 수정의 유연성을 확보하는 것이다. 객체와 작업은 각자의 계층구 조를 가지며, 이 계층구조는 실제 내용에 맞추어 가변형으로 정의하였다. 이는 효율성과 상세 성을 동시에 만족하는 구조다. 이 구조를 고속도로 건설공사에 시범적용 하였고, 범용 포맷을 이용해 구조를 디지털로 구현하였다. 본 연구는 현실에 가깝게 도로 건설공사 과정을 디지털화할 수 있으며, 도로건설 전주기의 디지털트윈의 토대가 되어 토목산업의 디지털전환을 가속화 할 것이다. The digitalization of tasks for smart construction requires the smooth exchange of digital data among stakeholders to be effective, but there is a lack of digital data standardization and utilization methods. This paper proposes a digital construction information structure to transform information from road construction sites into digital formats. The study targets include significant tasks, such as work planning, scheduling, safety management, and quality control. The key to the construction information structure is separating construction information into objects and activities, defining unit works by combining these two types of information to ensure flexibility in representing and modifying construction information. The objects and activities have their respective hierarchical structures, which are defined flexibly to match the actual content. This structure achieves both efficiency and detail. The pilot structure was applied to highway construction projects and implemented digitally using general formats. This study enables the digitalization of road construction processes that closely resemble reality, accelerating the digital transformation of the civil engineering industry by developing a digital twin of the entire road construction lifecycle.

새로운 불순물(dopant) 원료인 스핀온 쏘스를 사용하여 붕소를 실리콘천에 이단계 확산시키는 공정을 검토하였다. predeposition후의 확산충의 두께의 drive-in 확산후의 두께에 비하여 무시할 수 없이 큰 경우에 대하여 이단계 확산공정이 끝난 후의 확산층의 두께를 예측할 수 있는 간단한 방법을 제안하였다. 제안된 방법에 의하여 불순물 확산충의 두께를 예측하였으며 그 결과를 실험적으로 측정된 값과 비교하였다. The two-step diffusion process of boron into silicon has been investigated using a new diffusion source coiled "Spin-on Source". A simple method is proposei which can estimate the junction depth after the two -step diffusion for the cases where the junction depth after the predeposition is not negligible compared with the junction depth after the two-step diffusion. The estimated junction depths are, then, compared with the experimental measurements.surements.
The first record of Cyproidea liodactyla (Crustacea: Amphipoda: Cyproideidae) from Korean waters
정태원,서호영,윤성명 국립생물자원관 2016 Journal of species research Vol.5 No.3
The first record of Korean cyproideid amphipod, Cyproidea liodactyla Hirayama, 1978 is reported here with description and illustrations. This species has the following characteristics: the presence of dorsal keel of peduncle 2 on antenna 1, posterodistal process of ischium on gnathopod 1 and carpal process on gnathopod 2. In this study, the minor differences between the original description and our Korean specimens of Cyproidea liodactyla are discussed and a brief comparison to other related species such as C. serratipalma Schellenbeg, 1938 and C. robusta Ren, 2006 are suggested. In addition, a key to Korean species belonging to the family Cyproideidae is provided.

The main purpose of this study is to design the port marketing strategies for strengthening the competitive power of container terminal. So far many attempts have been made to analyze the international competitiveness of the terminal. Six factors hypothesized by this study come from previous research analyses about customers preference for port selection. Those are Cost Centrality and Intermediacy Free trade port Inland transportation connections Political and Economic institution and Port facilities. this study analyzes the most important factors about hob port and transhipment port separately through questionnaire analysis about users(shipper shipping company and freight forwarder) influencing on port selection. The results of this study were found as follows:

Measurement and discussions of logistics cluster competitiveness with a national approach are required to boost agglomeration effects and potentially create logistics efficiency and productivity. This study developed assessment criteria of logistics cluster competitiveness based on Porter’s diamond model, calculated the weight of each criterion by the AHP method, and finally evaluated and discussed logistics cluster competitiveness among Asia main countries. The results indicate that there was a large difference in logistics cluster competitiveness among six countries. The logistics cluster competitiveness scores of Singapore (7.93), Japan (7.38), and Hong Kong (7.04) are observably different from those of China (5.40), Korea (5.08), and Malaysia (3.46). Singapore, with the highest competitiveness score, revealed its absolute advantage in logistics cluster indices. These research results intend to provide logistics policy makers with some strategic recommendations, and may serve as a baseline for further logistics cluster studies using Porter’s diamond model.
