기존의 이동식 기준장비는 갓길의 폭이 1.5m 이하인 도로 구간에는 설치가 어려우며 장비가 크고 무거워서 차량과의 충돌 시 피해가 클 수 있으며 한 번에 다차로 검지가 불가능하다. 본 연구에서는 이러한 문제점을 노정하고 있는 기존의 이동식 기준장비의 단점을 극복하기 위하여 연구 개발된 USN-기반 이동식 기준장비의 특징을 기술하고 그 성능수준을 현장 적용을 통하여 평가하였다. 그 결과 본 연구에서 개발된 장비는 기존의 이동식 기준장비가 가지고 있는 운영상의 단점을 극복할 뿐 아니라 기준장비가 가져야 할 성능수준을 만족하는 것으로 나타났다.

현재 ITS 성능평가는 교통정보 수집 장비에 대한 평가를 중심으로 시행하고 있다. 하지만 교통정보 수집 장비에 대한 평가만으로는 도로 이용자에게 제공되는 교통정보의 신뢰성을 보장할 수 없기 때문에 ITS 서비스를 평가할 수 있는 제도적인 뒷받침이 필요하다. 본 연구에서는 도로 이용자가 제공받는 구간 통행시간정보의 정확도를 평가할 수 있는 방법을 검토하였다. 그리고 실제 도로에서 데이터를 수집하기 위하여 이동식 평가 기준장비를 개발하였다. 개발한 평가 기준장비에 대한 성능평가와 현장 여건을 고려한 평가 방법을 마련하기 위해, 서울청 관할 국도 2개 구간에서 시범평가를 수행하였다. 평가 결과, 서울청에서 제공하는 통행시간정보는 90% 이상의 정확도로 높게 나타났다. 시범평가 결과를 바탕으로 표본 수를 늘리기 위한 기준장비 검지 방식 개선과 수집지점 위치 조정에 대한 사항을 논의하였다.

Effective data exchange among the diverse stakeholders participating in a process plant project is an important issue. ISO 15926 is an international standard to support sharing and integrating of process plant data. iRINGTools is an ISO 15926-based tool used to exchange plant data. To exchange plant data using iRINGTools, the mapping between the data model of a commercial system and ISO 15926 should be preceded. To accomplish this, types and properties of equipment and materials used for plant design should be predefined and these data should be represented as user-defined reference data complying with ISO 15926. Besides, the user-defined reference data should be serviced by a reference data server such that iRINGTools searches reference data from the server and utilizes the data for the model mapping. In this paper, we present a method to construct a reference data server and use it for the model mapping in iRINGTools. The proposed method is verified through experiments of exchanging specifications data of equipment and materials using iRINGTools.

Zero energy building was attended for energy consumption minimization by the energy saving technology about building heating and cooling energy consumption and the renewable energy production facility. So the government has supported the zero energy building supply for decreasing green gas emissions. The study about inventory of zero energy building has many proceeding. That inventory need the information of material and equipment. So information of material and equipment about zero energy building must be included for the zero energy building realization. Actually the database of zero energy building inventory construction through the inventory established studies has difficult because the database need many information. In this study, author proposed the test methods and performance reference for upload at inventory. It was constructed to material - module - package. Also the author analyzed the construction of the technical package for zero energy building. The author separated performance category to the energy performance for energy analysis and other performance for confirmed the durability, stability and etc. This performance category proposed the table. The test methods of material and equipment in the passive package and active package proposed to the international standard and korea standard basically korea standard. Also the performance reference was proposed to korea legal standard and various standard by this study results. And the authors proposed the table of performance value, test methods, performance reference. By result of this study, the test methods and performance reference will be used the basic data for inventory of zero energy building.

The smart factory has developed with the help of several technologies such as automation, artificial intelligence, big data, smart sensors and communication protocols. The Internet of things(IOT) among communication protocols has become the key factor for the seamless integration of various manufacturing equipment. Therefore, it is important that the IOT cooperate with the standards of communication protocols proposed by the SEMI in the semiconductor industry. In this paper, we suggest a novel reference model of the communication protocols for semiconductor equipment by introducing an IOT service layer. With the IOT service layer, we can use the functions and the additional services provided by the IOT standards that give the inter-operability between factory machines and host computers. We implement the standard of the communication protocols for semiconductor equipment with the IOT service layer by using ns3 simulator. It concludes that it is necessary to provide the platform for the IOT service layer to deploy efficiently the proposed reference model of the communication protocols.

Previous test equipment was bulky, took a long time to check, and was somewhat less economical. Since most of the checks were about analog signals, we preferred to check them using reference equipments. In this paper, a digital circuit design based on AITS is used to implement signals that can not utilize commercial measurement resources, and also designed and manufactured equipment that can inspect SRU. These test equipments were tested and evaluated by development, operation, and field evaluation, and they were installed to the Korean Field Force. This contributed to the improvement of operability by shortening the inspection time from 83.2 minutes to 7.8 minutes on average In addition, it did not utilize the reference equipment, so it could play a big role in lowering the mass production cost.
