From a viewpoint of human factors, automated highway systems(AHS) can be defined as one of the newly developing human-machine systems that consist of humans(drivers and operators), machines(vehicles and facilities), and environments(roads and roadside environments). AHS will require a changed vehicle control process and driver-vehicle interface(DVI) comparing with conventional driving. This study introduces a fixed-based AHS simulator and provides questionnaire-based human factors evaluation results after three kinds of automated driving speed experiences in terms of road configuration, operation policies, information devices, and overall AHS use. In the simulator, the "shared space-at-grade" concept-based road configuration was virtually implemented on a portion of the Kyungbu highway in Korea, and heads-up display(HUD), AHS information display, and variable message signs(VMS) were installed for appropriate AHS DVI implementation. As the results, the subjects expressed positive opinions on the implemented road configuration, operation policies, and the overall use of AHS. The results of this study would be helpful in developing the road configuration and DVI design guideline as the basic human factors research for the future implementation of AHS.

The Ministry of Land, Infrastructure and Transport (MoLIT) and the Korean Automobile Testing and Research Institute (KATRI) are supporting the development of Lv.3 automated vehicle (hereinafter, AV) technology by constructing an automated driving pilot city (as known as K-City) equipped with total 5 evaluation environments (urban, motorway, suburban, community road, and autonomous parking facility) which is a test bed exclusively for AV (2017~2018). An upgrade project is in a progress to materialize harsh environments such as bad weather (rain, fog, etc.) and reproduction of communication jamming (GPS blocking, etc.) with the purpose of supporting the development of Lv.4 connected & automated vehicle (hereinafter, CAV) technology (2019~2022). We intend to proactively establish a national level standard for CAV test-bed and test road requirements, test method, etc. for establishment of a road map for the construction of the test bed which is being promoted step by step and analyze and, when required, benchmark the case of China that has announced and is utilizing it. Through this, we plan to define standardized requirements (evaluation facility, evaluation system, etc.) on the test bed for the development of Lv.4/4+ CAV technology and utilize the same for the design and construction of a test bed, establishment of a road map for the construction of a real car-based test environment related to the support for autonomous driving service substantiation, etc. through provision of an evaluation environment utilizing K-City, and the establishment of a K-City upgrade strategies, etc.

자율주행차의 안전성을 실효성 있게 평가하기 위해서는 기하구조, 교통안전시설, 혼잡도, 기상 등 다양한 항목들이 평가 시나리오 내에 고려될 필요가 있다. 이에 본 연구에서는 자율주행차 평가 시나리오에 반영되어야 하는 구성요소들을 도출하기 위해 먼저 평가 시나리오의 체계를 수립한 후 반영될 구성요소를 계층별로 범주화하였다. 이후 계층별로 관련 문헌을 검토하여 자율주행차 평가에 영향을 줄 수 있는 모든 평가 구성요소 후보를 도출한 후, 전문가 설문조사 결과를 바탕으로 총 77개의 자율주행차 평가 시나리오 구성요소들을 선정하였다. 선정된 자율주행차 평가 구성요소들은 시뮬레이션 평가, 주행시험장 평가, 실도로 평가 등에서 자율주행차의 안전성 평가를 위한 시나리오 개발에 많이 활용될 것으로 기대된다.

In this research, the automated system for 3D modeling and stability evaluation of caisson was developed. It is possible to build a BIM model while examining the stability of the structures to improve the practical use of BIM technology. This study analyzed industry cases and guidelines for caisson stability evaluation and BIM-based modeling. As a result, the data for calculating the stability evaluation of caisson as well as the modeling parameters were derived. In particular, the automated system for 3D modeling, which reflects more than 30 parameters, allows for BIM models for various types of the caisson, such as open-cell caisson, open-cell caisson with uneven, slit caisson, slit caisson with uneven, and curved caisson. The study tested the proposed system using case studies and found that it helps not only to automate the BIM model with various caisson types as parameters but also to make partial shape changes accessible. The study also confirmed that the stability evaluation can be quickly carried out with shapes changed. Finally, the study results suggest that the proposed method should complete the task seven times as fast as the conventional work method.

Inherently safe plants are maintained through the systematic identification of potential hazards, and various hazard evaluation methods have been developed. Recently, much effort is given into the development of automated hazard evaluation system by introducing the expert system. An automated system will help to obtain consistency and to make the result more reliable. HAZOP study is one of the most systematic and logical evaluation procedure. However, it has disadvantages: experts should participate at the same time, the detailed study requires much man-hour, and the results depend on the expertise of the experts. Therefore, the automation of hazard evaluation is necessary to reduce the required time and to get the consistent evaluation results. In this study, HAxSYM, an expert system to automate HAZOP study, is developed. The case studies are performed to validate the effectiveness of the developed system, and the results are compared to the results of traditional method.

Recently, many enterprises are installing AMSs(Automated Manufacturing Systems) for their competitive advantages. As the level of automation increases, proper design and validation of control logic is a imperative task for the successful operation of AMSs. However, current discrete event simulation methods mainly focus on the performance evaluation. As a result, they lack the modeling capabilities for the detail logic of automated manufacturing system controller. Proposed in this paper is a method of validation of the controller logic for automated material handling system using an object-oriented design and simulation. Using this method, FA engineers can validate the controller logic easily in earlier stage of system design, so they can reduce the time for correcting the logic errors and enhance the productivity of control program development Generated simulation model can also be used as a communication tool among FA engineers who have different experiences and disciplines.

자율주행 기술의 발전과 함께 자율주행차(automated vehicle, AV)의 안전성 평가의 중요성이 증가하고 있다. 이에 따라 효율적인 안정성 평가를 진행하기 위해 AV가 주행 중 직면할 수 있는 상황을 사전에 정의한 평가 시나리오를 활용하고 있다. 그러나 기존에 활용되는 시나리오는 짧은 구간 내에서 한정적인 상황만을 다루고 있다. 따라서, 실제 도로에서 발생하는 연속적인 상황을 평가하지 못한다는 한계가 존재한다. 이에 본 연구에서는 AV의 안전성을 강도 높게 평가하기 위해 단일 시나리오를 다양한 기하구조가 존재하는 도로 전체 구간을 대상으로 연속적인 평가가 가능한 다중 시나리오로 변환하고자 한다. 특히, 시나리오를 연결하는 조건을 정의하고, 변환된 다중 시나리오를 상황, 범위, 실험 시나리오로 발전시키는 구체적인 방법론을 제시하였으며, 시뮬레이션으로 다중 시나리오를 구현하여 검증하였다.

A one-step real-time quantitative RT-PCR assay in combination with automated RNA extraction was evaluated for routine testing of HCV RNA in the laboratory. Specific primers and probes were developed to detect 302 bp on 5'-UTR of HCV RNA. The assay was able to quantitate a dynamic linear range of $10^7-10^1$ HCV RNA copies/reaction ($R^2=0.997$). The synthetic HCV RNA standard of $1.84{\pm}0.1\;(mean{\pm}SD)$ copies developed in this study corresponded to 1 international unit (IU) of WHO International Standard for HCV RNA (96/790 I). The detection limit of the assay was 3 RNA copies/reaction (81 IU/ml) in plasma samples. The assay was comparable to the Amplicor HCV Monitor (Monitor) assay with correlation coefficient r=0.985, but was more sensitive than the Monitor assay. The assay could be completed within 3 h from RNA extraction to detection and data analysis for up to 32 samples. It allowed rapid RNA extraction, detection, and quantitation of HCV RNA in plasma samples. The method provided sufficient sensitivity and reproducibility and proved to be fast and labor-saving, so that it was suitable for high throughput HCV RNA test.
