To solve social problems such as traffic accidents caused by human driver factors and to guarantee the convenience of movement, research on the commercialization of automated vehicles is being actively conducted worldwide. In automated driving levels 2 and 3, the driver must be ready to drive at any time as the automated driving system sometimes requires manual driving by the driver. The purpose of this research is to analyze the trends in global automated vehicle guidelines and prepare guidelines for the characteristics of human factors necessary for the control rights transition system of automated vehicles. To this end, we reviewed at the guidelines for automated vehicles in the US, Germany, and Japan; ISO international standards; domestic automated vehicle standards; and the EU AdaptiVe project. In addition, a guideline is presented that can be referenced and applied by organizations related to automated vehicle manufacturing and operation. It was developed by utilizing the results of our studies on the human factors affecting the guideline of control rights transition. As national laws and regulations and continuous technology development for commercialization of automated vehicles are in progress, further research into and the revision of guidelines for safe automated vehicle production and use should be continued.

In order to become a mega hub port, major ports all over the world are making every effort to enhance their productivity through efficiency of internal operation. Accordingly, in order to enhance the competitiveness of a container terminal, an automated container terminal is considered as the best alternative. An automated container terminal is using such automated handling equipment as AGV(Automated Guided Vehicles) and ATC(Automated Transfer Crane). The efficient equipment operation plays a critical role in enhancing the productivity of an automated container terminal. In an automated container terminal, the most important equipments are AGV and ATC. Each block of containers with a vertical layout is generally operating two ATCs. The two ATCs can be crossed or not at each block. In the case of operating crossover ATC, it has an advantage of high flexibility that ATC work is possible at both TP(Transfer Point) of each block. But it has also a disadvantage that the yard has to be operated at a low storage level of containers in the terminal yard. Recently, for automated container terminals, which are being prepared for opening in Korea, they plan to use uncrossed twin ATC in order to make the storage level of their yards high at a low cost. Therefore, studies have to be made in order to increase the efficiency of twin ATC system based on the flexibility that the crossover ATC system has. This research aims to suggest an operation strategy to improve efficiency of twin ATC at each storage block in a yard.

The automated construction machines have been recently developed to help solve the construction industry problems that significantly affect labour, productivity, quality, and profit. Despite the importance of performance analysis to commercialize the automated construction machines, previous studies have mainly concentrated on developing hardware and software of automated construction machines. This research now focuses on two objectives: (1) to propose an analysis model which can measure productivity, quality, and safety improvement rate of automated construction machines based on research and development (R&D); and (2) to develop a performance analysis system which will aid the evaluator in analysing the performance of automated construction machines. Finally, it is anticipated that the effective use of the performance analysis model and computerized system will ably develop the high-performance, automated construction machines and establish the marketing strategy to increase not only the commercial value but also the upkeep and development of construction machines.

Purpose: This study was undertaken to investigate the feasibility of using automated liquid-handling systems equipped with reusable fixed tips in Radioimmunoassays and to demonstrate that the use of an automated pipetting instrument can decrease in the typical daily workload. Materials and Methods: The precisions of the automated pipettor and the manual pipettor were determined gravimetrically (n=30). A total of 30 specimens for HBs Ag were repeatedly pipetted (three replicates) with the automated pipettor and then retested. PSA samples were simultaneously pipetted with either the automated pipettor or the manual pipettor and then analyzed (n=40). Sample carryover test assessed for CA19-9, AFP and HCG when the automated pipettor was used. Pipetting speed of the automated pipettor and the manual pipettor were compared by evaluation of each workload. Results: The precisions coefficients of variation (CV) were 2.1% for the automated pipettor and 1.6% for manual pipettor. The mean cpm and CV for each group of replicates were 41,203 cpm and 3.7% for HBs Ag positive specimens, and 99 cpm and 7.9% for HBs Ag negative specimens, respectively. PSA results showed no significant differences between automated pipettor and manual pipettor (p=0.15, r=0.999). Carryover for CA19-9, AFP and HCG analytes was <0.1 ppm or below the assay limit of detection. Pipetting speed was significantly improved by using the automated instrument. Conclusion: There was no evidence that the use of an automated pipettor adversely affected any of the performance characteristics of the assay. Indeed, routine use of the Tecan automated pipettor has resulted in a decrease in the typical daily workload.

Automated container terminals have been being developed over the world for recent years and many countries are interested in it because the amount of containers exported or imported is rapidly increasing. The conventional container terminals were not designed to control this kind of heavily many containers. They would face many structural problems soon or later, although they have managed to do well so far. One of the most important things in developing automated container terminal is to develop the equipment able to handle many containers efficiently. Those are maybe automated transfer cranes, automatic guided vehicles, and automated quay-side cranes. The word 'automated' means the equipment is operated without drivers and those equipments are able to work without any interruption in working schedule. Through the researches on the conventional transfer cranes, we decided that the structure of the conventional transfer cranes is not efficient in automated container terminal and it's not possible to handle so many containers in limited time. Therefore we have been studying on the proper structure of the automated container crane for past several years and a new type of transfer crane has been developed. Design concept and control method of a new type of transfer crane had been presented in the previous paper: Part Ⅰ. Experimental features will be presented with a model transfer crane in this paper: Part Ⅱ.
