Occupational therapists (OTs) interface patients much longer than other healthcare workers and, thus, are likely to experience a high level of stress because of work, physical fatigue, lack of professional knowledge and skills, and problematic relationships with patients, etc. This study examined the quality of the lives of OTs and the workplace which is an influential factor. This study recruited 200 OTs and used a professional quality of life scale. We found that, only 27.0% experience high levels of compassion satisfaction (CS) and 80.5% and 74.5% experience high or average levels of burnout (BO) and secondary traumatic stress (STS) of compassion fatigue (CF), respectively. We discovered that CS was higher in temporary employees; and CF was higher in females, subjects in their 30s; and those working at general hospitals. Also, BO was higher in those with one to five years of clinical experience and regular employees. Last, STS was higher in the group without stable income. This study verified that clinical experience is a critical factor that reduces BO, and excessive workload outside of treatment lowers the professional quality of life. This suggests that work environment and regulations related to OTs must be improved to increase CS and reduce CF.

The construction industry remains serious accidents, injuries, and fatalities due to it's unique, dynamic, and temporary nature. On workplace sites, Safety pre-task planning is one of the efforts to minimize injuries and help construction personnel to identify potential hazards. However, the working conditions are complicated. Many activities, including tasks or job steps, are executing at the same time and place. It may lead to an increase in the risks from simultaneous tasks. This paper contributes to addressing this issue by introducing a safety risk interaction analyzing framework. To accomplish this objective, accident reports of the Occupational Safety and Health Administration (OSHA) are investigated. The pairs of task incompatibility, which have time-space conflicts and lead to incidents, are found. Ontology technology is applied to build the risk database, in which the information is acquired, structuralized. The proposed system is expected to improve pre-task planning efficiency and relieve the burdens encountered by safety managers. A user scenario is also discussed to demonstrate how the ontology supports pre-task planning in practice.

In order to achieve effective human resource development in LIS fields, it is essential to have strategies to nurture and utilize those human resources, in relation to supply and demand as well a sound legal foundation supporting those strategies. Such strategies and legal foundation can only be developed from a complete knowledge of the current status of human resources in the LIS and related industries. This study, therefore, conducted research on the basic employment status, employment environment, and an overall analysis of related issues, in order to address policy implications on the effectiveness of human resource development in the LIS field. This research included the current status of policy environments that involve social environment, and related institutions and laws, and human resources developments as well as the current requirements of librarians in the field, based on a demand survey of LIS employment. It was found that first, there are three distinguishable factors in LIS employment: a feminization of librarianship, an increase in temporary posts, and a high entering ratio into the library workplace. Second, while there were only little differences in the given tasks between full-time and temporary employees, the differences in salary and welfare were considerably larger. Third, field requirements for librarian education included a mentoring system with field experts, short-term internships, and librarian apprenticeships, while job requirements included internship or apprenticeship, language skills, various license acquisition, and career management. Fourth, librarians with licenses for related organizations held 20% more librarian licenses overall.

In this year, Koreans have a shortage in agricultural and drinking water due to severe algal blooms generated in major lakes. Waste oyster shells were obtained from temporary storage near the workplace at which oysters were separated from their shells. Heating ($1000^{\circ}C$ for 1 h in air) was employed to convert raw oyster shell powders into calcium oxide powders that reacted efficiently with phosphorus and nitrogen to remove algal blooms from eutrophicated wastewater. As the dispersed amount of heated oyster shell powders was increased, water clarity and visual light penetration were improved. Coagulation, precipitation and carbonation process of the heated oyster shell powders in a water purifier facilitated removal of eutrophication nutrient such as phosphorus and nitrogen, which is both beneficial and economically viable. $CO_2$ implantation by carbonation treatment not only produced thermodynamically stable CaO in oyster shells to derive precipitated calcium carbonate (PCC) but also accelerated algal removal by activation of coagulation and precipitation process. The use of oyster shell powders led to a mean reduction of 97% in total phosphate (T-P), a mean reduction of 91% in total nitrogen (T-N) and a maximum reduction of 51% in chemical oxygen demand (COD), compared with the total pollutant load of raw algal solution. Remarkable water quality improvement of algal removal by heated oyster shell powders and PCC carbonation treatment will allow utilization as water resources to agricultural or industrial use.

Objectives: Acute methanol poisonings known to be typical occupational diseases occurring in developing countries broke out in sub-contract manufacturers in the early 2016. The present paper attempted to identify underlying causes which hide under apparent findings, and suggest alternative policies to prevent recurrence of similar intoxication Methods: We evaluated occupational health and safety characteristics of workers in micro-enterprises similar to workplaces with methanol poisoning by in depth-interview of employers, workers, and labor inspectors, and literature review. Results: The common findings of workplaces with methanol poisoning were addressed; First, the victims were illegal agency workers. Second, the workplaces were sub-contract micro-manufacturers with less than 5 employees. Investigators found that local ventilations did not work, while most of workers did not wear any proper personal respiratory protective equipment in the workplace. In addition, periodic environmental monitoring and medical check-ups were not done. However, these apparent findings do not appear to be root causes of methanol poisoning. Our in depth-analysis clarified a root cause; micro-enterprises with less than 5 employees are exempted with essential regulations of OSH Act, and employers do not know about OSH Act. Conclusions: We suggest occupational health policies to prevent recurrence of similar intoxication; First, government should introduce programs so that all employers should know about employers' responsibilities in OSH Act from the start of business. Second, even manufacturers with less than 5 employees should not be exempted with essential regulations of OSH Act. Finally, employers should take responsibilities for health and safety of all the workers including agency workers working in workplaces.

This paper aims to examine whether there are significant differences in various aspects of a household's arrangements by type of employment of married woman; 1) the extent of the division of labor, 2) the authority of decision making, and 3) financial and expenditure responsibilities. It also investigates the determinants of gender equality in the family. Based on data collected in the fall of 2002 from a representative sample of the Korean population, this study finds that nonstandard employment of married woman including temporary work and daily basis work does not contribute to gender equality within the household, although most of nonstandard employees are full-time workers. However, standard employment of married woman contribute to gender equality in the family. The results of this study show that husbands whose wives are standard-employed are more likely to take part in housework chores that are female-dominated, and standardly employed wives are more likely than non-standardly employed or housewives to take part in the household's financial and expenditure responsibilities. Standardly employed wives also have more power in decision making process within households. On the contrary, non-standardly employed wives gain no advantage over housewives within their families, due to lack of bargaining resources that enable them to affect the household's arrangements. Thus, they have confronted additional burdens, which stem from carrying the dual role of doing house work as well as paid work. Such increasing work-family conflict may bring about disruption of family. Therefore, this study maintains that it is high time that government-level efforts should be made in order to improve the status of irregularly employed wives in the workplace.

The present study examines the dialectic tensions arising within the ICT-mediated labor culture between the dominant power of conglomerates and the precarious labor subjects in the labor practices, as smartphones and tablet PCs have grown in popularity. The present study explores how much young precarious workers named 'Cheongyeon Alba' (young precariat in S Korea) suffers from continually precarious job positions as temporary staff or contract workers, being trapped at the bottom of the pay scale, and also being electronically connected to the workplace in a seamless way. Concretely, this study investigates how the mobile phone becomes deeply entangled with the 'precarious' labor culture in the metropolitan city of Seoul. The mobile precariat has been in a disadvantaged position, in terms not only of the moral issue of exploitation in business but also of social injustice. Labor exploitation of young workers has been reinforced by the mobile labor culture, in which they are remotely monitored by live surveillance mobile apps, and mobile instant messaging from a boss can intrude incessantly into their private life. This study depicts the extension of the business's surveillant power by mobilizing the mobile phone in the working practices.

This study analyzed workers' residence and home-based work(HBW) trip by utilizing data from mobile carrier base stations of Gwangyang Port and terminal workers. In the past, research on port-related traffic or trip patterns mainly focused on cargo-based movement patterns for estimating cargo volume and port facilities, but this study analyzed trip patterns for workers in Gwangyang Port ports and related industries. As a result of the analysis, the average number of regular workers in the port hinterland Gwangyang Port was 1,295 per month, and the residence of workers was analyzed in Gwangyang City (66.1%)>Suncheon City (26.6%)>Yeosu City (3.1%). The average number of temporary workers in the hinterland was 2,645 per month, and Gwangyang City (45.8%)>Suncheon City (20.1%)>Yeosu City (5.7%). Next, the average number of regular workers at Gwangyang Port terminals was 753 per month, and Gwangyang City (66.1%)>Suncheon City (28.9%)>Yeosu City (3.3%) was analyzed. The average number of temporary workers at Gwangyang Port terminals was 1,893 per month, and Gwangyang City (50.8%)>Suncheon City (19.7%)>Yeosu City (9.8%). This study is expected to calculate the number of workers based on individual traffic using actual mobile carrier data to estimate the actual number of workers if the workplace address and actual work place are different, such as in port-related industries. This study is the first to be conducted on workers at Gwangyang Port. It is expected to be used as basic data for settlement conditions and urban planning, as well as transportation policies for port workers, by identifying the population coming from areas other than Gwangyang, where Gwangyang Port is located.

The purpose of this study was to determine the oral health condition and behavioral status of Korean adults according to occupational status. The subjects were 7,676 adults, aged between 19 and 64 years, who completed both oral examination and questionnaire survey, among those who indicated that they were currently participating in economic activities, according to the data from the Fourth Korea National Health and Nutrition Examination Survey. Occupational class and employment status were selected as measures of occupational status. Complex-samples logistic regression models were used to assess the associations among oral health, behavioral, and occupational statuses. We found a significant occupational class-related difference in the oral health and behavioral statuses of both the men and women. In particular, the prevalence odds ratios of untreated dental caries in manual workers were 1.19 and 1.67 times higher than in non-manual workers, for men and women, respectively. As for oral health condition and behavioral status according to employment status, the health risk in temporary employment workers was higher than that in permanent employment workers. As for the prevalence odds ratios of the risk of dental caries, the highest values were observed for tooth brushing fewer than 3 times per day, not undergoing oral examinations, and chewing difficulty complaints. The risk of dental caries for agricultural, forestry, and fishing workers for both men and women was found to be the highest among other workers. Thus, strategies to promote workplace oral health in the microscopic and macroscopic perspectives should be developed to constantly monitor oral health problems, and to identify vulnerable social groups within occupational groups and the related factors that mediate oral health differences.
