In this paper, we developed a working adaptation evaluation system using finger force measurement which interact between material and biological system. The system consists of a finger force transducer, a signal conditioner, an A/D converter, a computer, and a software system for data processing. The finger force transducer is made by a load cell and a special mechanism. The data processing software controls the A/D converter, data monitoring, and data analysis for group classification. The developed system were tested by 4 different materials in left hand and the finger forte transducer in the other hand's thumb and index finger with 16 persons. As the results of experiments, the developed system could measure the finger force quantitatively and classify the measured values into four groups.

Surveillance cameras have been installed in many places because security and safety has become an important issue in modern society. However, watching surveillance videos and judging accidental situations is very labor-intensive and time-consuming. So now, requests for research to automatically analyze the surveillance videos is growing. In this paper, we propose a surveillance system to track multiple persons in videos and to summarize the videos based on tracking information. The proposed surveillance summarization system applies an adaptive illumination correction, subtracts the background, detects multiple persons, tracks the persons, and saves their tracking information in a database. The tracking information includes tracking one's path, their movement status, length of staying time at the location, enterance/exit times, and so on. The movement status is classified into six statuses(Enter, Stay, Slow, Normal, Fast, and Exit). This proposed summarization system provides a person's status as a graph in time and space and helps to quickly determine the status of the tracked person.

In this study, the current regulations to be adequate in industrial site have to be renew in order to prevent the fatal injuries by mobile cranes. Fatal injury analyses were conducted with several accident cases by the mobile cranes. For each accident, the causes of the injuries were examined and proper safety measures were proposed. This study proposed a revision of the standard guideline as an accident prevention measures through in-depth analysis of fatal accidents. First, fatality rate per 10,000 persons by the mobiles cranes was 0.57 in 2011. Second, the in-depth analysis of the mobile crane accidents showed that the main factors of the accidents were the overturn of mobile crane, the fracture of connection part between mobile crane boom and rope, the breaking of rope and the misunderstanding over the signal between a mobile crane driver and workers around a mobile crane. Third, the order of high defection of connecting parts was bucket bolt, bracket and extension parts. Fourth, since there were several cases of overturn of mobile crane by itself in the in-depth analysis of the mobile crane, the over slop-proof device was proposed as the main alternative in this study. Fifth, the revision of standards of safety factor that shall be more than 10, of connecting parts of mobile crane was proposed.

Since reports on trip delays or incidents often appear as accident articles on the press, the social criticisms and concerns on the safety of the urban railway are increasing. Therefore, a railway authority sometimes adopts an abstract safety goal like "let's build the urban railway to a masterpiece level" or "let's obtain an aeronautic safety level" to make citizens relieved and to alert involved persons. However with a vague goal, it is almost impossible to make an implementation plan systematic which helps the authority academically verify and validate if the goal is achieved or not. In this paper, the features of the railway safety are described and the safety models for securing the safety of the urban railway are surveyed and categorized. Based on the comparisons among the features and limitations of the models, we identify a more practical model which can be applied to the urban railway more effectively.

For last decade, the number of foreign workers in all industries has been increased continuously. In the construction industry, the number of foreign workers has also increased as 80,000 persons in 2010. According to the increase of foreign workers at domestic construction sites, the frequency of construction disasters has increased as well. The safety education can be a effective solution to decrease the construction disaster. So, it is necessary to develop the appropriate education system for foreign workers. Therefore, the objective of this study is to propose a safety education model for foreign workers and to develop the prototype system. In a result of that, a new safety education model and prototype system was constructed based on the method of E-learning. The system can support for foreign workers in domestic construction sites to understand the safety education easily. And, it can also assist the safety manager to educate and manage the foreign workers efficiently.
