    The knowledge of the soldering process in producting metal fittings of flags is based only on tacit knowledge, such as knack and intuition. Therefore, it is necessary to make tacit knowledge into explicit knowledge. The purpose of this study was to investigate the process of soldering and the characteristics of human movements during the soldering process. Three-dimensional upper extremity kinematics and eye movement data were collected. The resulting data showed that the process was divided into four stages: “preparation”, “pre-assembly”, “assembly” and “post-treatment”. Motions during the assembly stage suggested that skilled workers controlled the temperature of a soldering bit by checking the speed of solder wettability. In the motions which made the soldering iron come and go between the base material and solder, the metacarpal phalangeal joint of the right forefinger began to move earlier than the eyes, the eyes caught up with the right forefinger, passed it, and reached the solder earlier than the forefinger. In the end, the right forefinger and the eyes returned to the starting position of the cycle.

    Sudden illness of vehicle drivers causes approximately 10% of traffic accidents. It is essential to promote, health management of drivers as an effective precaution against traffic accidents. In particular, the poor physical conditions of taxi drivers, leading to incidence of traffic accidents, is attributed to their difficult employment circumstances, influenced by deregulation. Another relevant factor is the age of drivers. For example many taxi drivers are reportedly at the risk of developing cerebrovascular and heart-related diseases. Cooperation of employers and taxi drivers and occupational physicians is necessary to prevent traffic accidents caused by the poor physical conditions of drivers. In addition, the government and the taxi industry can introduce a system to support the health management of taxi drivers

    Employers assume the obligation to manageing the mental and physical health of taxi drivers. Therefore, when a taxi driver causes an accident because of his poor physical condition, the employer may be liable to criminal, administrative, and civil responsibilities. Specifically, criminal liability includes fine punishment and penal servitude. Civil liability refers to compensation for damages. Administrative responsibility incorporates orders such as the suspension of vehicles. Such cases may erode social trust and result in economic losses. In recent years, cooperation between the Department of Transportation and the Labour Standards Office has been strengthened. Moreover, as public awareness of traffic fatalities and injuries from accidents increases, in which the liability of employers is strictly investigated may increase. The common opinion is that employers should ensure appropriate health management of taxi drivers to prevent traffic accidents.
