This study aims to evaluate job satisfaction level of employees working at special libraries by analyzing their affiliated institution and personal backgrounds. Results indicated that the job satisfaction level in private institutions was higher for 'remuneration', 'promotion', and 'overall satisfaction' in comparison to public counterparts. Also, employees working at institutions with independent libraries had higher level of satisfaction for 'work itself', 'remuneration' and 'co-workers' in comparison to those working in non-independent libraries. In terms of employment status, satisfaction level for 'remuneration' and 'promotion' was high among permanent employees, whereas 'superior and supervisor' was relatively higher among temporary employees. In terms of position, supervisors had higher level of satisfaction for 'remuneration', 'job system', 'promotion' and 'overall satisfaction' in comparison to non-supervisors. Employees with degrees in library and information science had higher level of satisfaction for 'work itself', 'job system', 'promotion' and 'institutional environment' in comparison to non-majors. This study clarified desires and emotions of employees working at special libraries and eliminated obstacles to higher job satisfaction. These findings may have implications for the improvement of work efficiency in libraries.

Objectives: We examined gender differential changes in employment-related health inequalities according to occupational position (professional/nonprofessional) in South Korea during the last decade. Methods: Data were taken from four rounds of Social Statistical Surveys of South Korea (1995, 1999, 2003, and 2006) from the Korean National Statistics Office. The total study population was 55435 male and 33913 female employees aged 25-64. Employment arrangements were divided into permanent, fixed-term, and daily employment. Results: After stratification according to occupational position (professional/nonprofessional) and gender, different patterns in employment - related health inequalities were observed. In the professional group, the gaps in absolute and relative employment inequalities for poor self-rated health were more likely to widen following Korea's 1997 economic downturn. In the nonprofessional group, during the study period, graded patterns of employment-related health inequalities were continuously observed in both genders. Absolute health inequalities by employment status, however, decreased among men but increased among women. In addition, a remarkable increase in relative health inequalities was found among female temporary and daily employees (p = 0.009, < 0.001, respectively), but only among male daily employees (p = 0.001). Relative employment-related health inequalities had clearly widened for female daily workers between 2003 and 2006 (p = 0.047). The 1997 Korean economic downturn, in particular, seemingly stimulated a widening gap in employment health inequalities. Conclusions: Our study revealed that whereas absolute health inequalities in relation to employment status increased in the professional group, relative employment-related health inequalities increased in the nonprofessional group, especially among women. In view of the high concentration of female nonstandard employees, further monitoring of inequality should consider gender specific patterns according to employee's occupational and employment status.

This work examines reemployment processes through the use of event history unemployment data in the United States. Two aspects of these processes, the duration of unemployment and changes in the reemployment rate, are modelled and analyzed in terms of individual characteristics and their structural positions in the labor market. The secondary labor market is a competitive market in which unemployment occurs because people quit their jobs to devote more time in search for better jobs. Using search theory, the rate of reemployment has a positive time dependence as the searcher lower her reservation wage with the passage of time. By contrast, the primary market is characterized by long-term employment relations which reduce voluntary turnovers but generate layoffs temporarily. Relying on contract theory, because workers on temporary layoffs wait for recall, reemployment rates have a constant time dependence. Empirical results of unemployment durations indicate that reemployment processes are influenced by individual's positions in dual labor market structures. While the analysis suggests that the amount of search reemployment seems to be positively related to the degree of competitiveness of a market, somewhat weaker results are noted in the search reemployment processes in competitive markets.

Nowadays, the power quality issue becomes very important in the electric distribution system. Especially, when a distribution transformer is replaced, the customers who are supplied electricity from the transformer feel inconvenience due to electric outage. Therefore, an advanced method for the distribution transformer replacement without outage is strongly required. The conventional method is the primary-secondary high voltage bypass method according to the transformer utilization factor and the field condition. But it is inconvenient and has some problems such as breakdown and security troubles of the workers according to the unauthorized and temporary work. Therefore, the new scheme for the replacement with uninterruptable power supply is demanded. This paper proposes the new replacement method using the phase converter. The proposed method can reduces the process of replacement work and also ensures worker's safety. Therefore, the method is reasonable in comparison with the conventional method. The proposed method is able to contribute the national economy growth and elevate the convenience of national life by uninterruptable power supply.

This study was conducted for the torsional behavior of catwalk system which is a temporary structure on a suspension bridge. The torsional deformation of the catwalk structure has a significant effect on the workability and safety of workers during main cable erection. For this reason, the torsional deformation of catwalk is controlled to be acceptable levels below by adjusting the cross bridge interval in design stage. This study analyzed the effect of separation between cross bridge associated with twist safety of catwalk system. For the analytical approach, a detailed analysis model was created including cross bridge. Both wind load within the wind velocity range that allows the construction and eccentric load of Prefabricated Parallel Wire Strand were analyzed by analysis model. Result of study shows that separation between cross bridges has a significant effect on the torsional behavior of the catwalk.

This study, with a view point to prevent accidents arising from steel structure, construction process, has taken an approach of reviewing related materials and construction safety guidelines, conducting questionnaire surveys and on field surveys. This study has also analyzed and classified accident cases and disclosed elements concerned with those accidents. A comparative analysis of the disclosed elements against the statutory provisions regarding industrial safety and it showed that strict observance of safety rules of the accident prevention measures in industrial safety standards will result in a decrease in accidents. It is concluded, however, that additional accident prevention measures, as suggested below, should be implemented for performing of more practical and positive accident prevention. 1) Thorough review and preparation at pre-working stage at sites : Such elements of fall preventing facilely as supporting ropes and steel fabrications for safety guard rails should be initially reflected on detailed drawings and shop drawings so that they can be installed in advance at fabricating plants. 2) Sets of steel frame stairs for work platform should be installed or secured with priority and temporary installation of such prefabricated platform as scaffolds should be installed in advance with those platform attached to the frame members on the ground whenever possible before they are lifted. 3) A decrease in the rate of accident by more than 10% on Tuesdays and Thursdays, has been shown from the accident analysis so schedule of construction process should consider possible weekday of high risk of accidents such as Tuesday and Thursday. 4) An array of systemized safety activities should be adopted, such as legal installation of safety facilities based on advance safety management plan, maintenance of safety for machinery and construction equipment, and strict compliance of safety rules by workers.

The Korean film market has revved up against American movies and the movie industry has continued to grow even though Korea is a small country. However, most production staffs who are responsible for practical business of film production get wages that fall short of the inflation rate and minimum wages as temporary employees. And there's the atmosphere that they try to leave film sites on the first opportunity. This study finds that the cause to leave film sites is attributed to perception gaps about the hardworking character and labor which occur in the process that production staffs enter the movie industry and participate in film production as well as poor surroundings. And it should establish staffs' hardworking character and recognition as workers to them by reorganizing the current curriculums which approach movies from the only artistic viewpoint in the departments related to movies and images that hold a large majority in their majors, establishing the concept of work according to participation in film production to potential production staffs, and changing their recognition to improve the elements that they leave the sites.

This paper reports problems of current working environment on construction site in South Korea from a female laborers' point of view and proposes solutions to improve the environment. To investigate and analyze the problems, a questionnaire survey and a focus group interview were conducted with 341 engineers and 557 laborers. Among them female engineers and female laborers were 51 and 136 respectively. Findings are the facilities related with welfare facilities such as lavatories, shower rooms, lounges and changing room, etc. for women were not sufficient and even not installed only for women because all of the planners for the facilities were men and The Standard of Estimate does not consider gender distinction. The data on the trade and the number of female laborers were not recorded and this study confirmed the number and the proportion of female laborers according to construction progress i.e. the proportion of female laborers were 0% ~ 11% (average 6%) at 26 construction sites having 2% ~ 92 % construction progress. In order to solve these problems, gender education for the welfare facility planner is required and the current Standard of Estimate should be revised considering female laborers after collecting the site data for the number of female laborers according progress and the increase in the construction cost should be reflected in the contract amount accordingly. Conclusively temporary work planning related with welfare facilities should be established and conducted in terms of gender equality at construction sites. In addition, improving working environment on construction sites for female laborers will enhance the company's image and also helping solve the labor shortage problem by women laborers engaging in construction industry easily.

Unsafe and dangerous factors or environments on building construction sites often cause safety accidents. Sometimes, accidents happen despite the existence of warning and caution signs. Such warning signs are likely to be hidden by stacked materials or temporary facilities on site. If workers cannot see the signs when moving or working, they could be injured, sometimes fatally. Many studies have focused on each worker's position, and various systems have been developed using GPS signals and sensors. This paper suggests a method for identifying the problem of worker inability to see the unsafe factors, to manage the problem in the construction planning phase by considering things from the worker's perspective. The method uses CAD software to investigate the relation between the height of stacked materials and the visible ratio of the unsafe factor. The results of a sample project show that the changes in the height and location of stacked materials make the site safer.

Appreciable radiation exposures certainly occur in the workers who handle radioiodine in biochemical research, nuclear medicine diagnostics with the development of nuclear industries. But in the case of occurring the nuclear accidents, the early medical treatment of radiation injury should be necessary but little was reported in korea till now. Accordingly, to achieve of the basic data for protective roles and medical treatment of radiation injury, the present studies were carried out to evaluate the decontamination of radioiodine by the administration of the antithyroid drugs. The results observed are summarized as follows: 1. The administration of sodium iodide and potassium iodide results in rapid excretion of radioiodine and reduction of the whole body retention than the saline-only group. 2. Reguarding to thyroid protective effects, sodium iodide, potassium iodide and saline were effected significant in order. 3. In the control(saline) group, if administered with enough fluids, the whole body retention of radioiodine is reduced temporary shifts. But as far as radioprotective effects is concerned, saline was not more in the protective effects than the other groups. In conclusion, in case of nuclear accidents, if being administered sodium iodide and saline as quickly as possible, the radioprotective effects against the radiation hazard might be markedly increased in the internal contamination of radioiodine.
