The aim of this study is to analyze determinant factor on the strike action among hospital laborer in Korea. We collected data for 10days from 12 to 22 July, 2013. This study was surveyed 405 laborer in university hospital was located in the Seoul city and Gyeonggi-do. It was found as follow. There was statistically significant difference in the strike propensity and sub-domain on the job dissatisfaction by sex, age, education, wedding, occupation, position, salary, number of years of employment, position in labor union for strike action(p<0.05). From the multiple regression analysis, it was found that determinant factor on the strike action was occupation, strike propensity(sense of duty, after vote, depend on compensation) which was statistically significant difference(p<0.05). As a result, we suggest that hospital administrator must solve the problem related welfare benefits and personnel system in university hospital for preventing strike.

This thesis discussed the status of women workers as wage laborers and home laborers and the valid of a documentary movie for representing women laborers through a documentary movie, Weabak that revolved around Home-ever occupation strike leaded E-Land labor union at 30th June, 2007. Jobs for women labors got covered by the flow of flexibility with the policy of labor flexibility in South Korea during 1990s. The reasons that justify this trend are their position in the households, and their roles in working places are not very important because there are not required difficult skills. The mass dismissal which caused the E-Land strike also shared these ideologies. In Weabak, since women laborers were always expected to care for their family, they were need strikes in their home as well as their working place. However, a household is a basement for them to get the identity as a women laborer. It has two ambivalent meanings, as a protected area and disorder for them to pursue their life at the same time. Identity of Women laborers, domestic laborers as well as wage laborers, are very difficult to identify as a general noun, a laborer. Weabak is an important example to show us the possibility of a documentary as searching new realism for representing women laborers' story using their own perspective.

For the D.P.T. and Polio the rate of above 35 year group was the highest but the completion rate of the vaccination and the regular vaccination rate were the highest in the age of 30-34 year group. 3. In 1982. the higher the educational levels of tile mother were, the higher the vaccination rates for B.C.G., D.P.T. and Polio were. 4.

Real time location (RTL) system which can control the safety of laborers in the underground space is developed in this study. This innovative system can monitor the location and history of movement of multiple laborers in real time. To accommodate constrains of the underground space, the system is portable and composed with low-battery mode. Since conventional method to detect the location of laborer with radio signal strength indicator (RSSI) contains high errors, new measurement system using accelerometers and correction method are suggested in this study. Field test is performed to validate the developed system. The error for moving laborer was 0.4 m and for non-moving laborers was 0.2 m. Thus, it is found that the new RTL system can be used to monitor the location of laborers in the underground construction space.
