The primary goal of this study was to investigate factors affecting job satisfaction of injured workers who returned to work. There are two types of injured workers' returning to work returning to pre-injury job and getting a new job. After separating the two types of workers we conducted the multiple regression analysis on the data from the Workers'Compensation Insurance Panel of the Korea Workers' Compensation and Welfare Service Corporation(2014). The sample consisted of 1,333 occupationally injured workers who were finished with medical treatment(693 workers returned to previous work place, and 640 workers found new work places). Main results are as follows. First, injured workers who got new jobs were vulnerable to sustainability to job, work status, average monthly wage as well as job satisfaction compared with injured workers who returned to pre-injury job. Second, gender, educational level, skill fitness, average monthly wage, welfare benefits, family income/leisure life/residential environment/social relation satisfaction, and maintenance of relation with business owner during medical care were related to job satisfaction of injured workers who returned to pre-injury job. Third, gender, work status, skill fitness, continuous work possibility, average monthly wage, family income/leisure life/social relation satisfaction, substitute worker for assigned task during medical care and maintenance of relation with business owner during medical care affected on job satisfaction of injured workers who got new jobs. Based on these findings implications for policy and interventions were discussed in regards to job satisfaction of injured workers.

Breast tissue is composed of skin, mammary gland(including lactiferous duct), subcutaneous fat layer. The anatomical position is on the anterior chest wall(the outside of the chest cavity) but not on the inside of the thorax. Therefore, when the internal organs in the thoracic cavity are defined and expressed as 'organs' and the internal organs of each are labeled for a long time, for the breast located outside the thoracic cavity, it is thought that there is considerable difficulty in defining and recognizing the breast tissue as organs. For this reason, it is necessary to discourage the controversy over whether or not the breast is contained in the chest(or intra-thoracic cavity). In order to completely exclude it, it is assumed that the "chest-abdomen" can be called the "intra-thoraxic or intra-abdominal." But it is difficult to change the terms in various laws and regulations, I think that it would be necessary to insert only the clue clause "Breasts are excluded" in the detailed criteria for grading. In order to include it, it is necessary to change the terms of the ordinance or to say that the breast is exceptionally included.

The purpose of this study is to provide policy recommendations for manpower planning by forecasting the supply and demand of Medical Technologists. Supply was estimated using an in-and-out movement method with a demographic method based on a baseline projection model. Demand was projected according to a demand-based method using the number of clinico-pathologic examinations taken for Medical Technologists. Over- or undersupply of Medical Technologists will depend on the productivity scenario and assumptions and ultimately on governmental policy direction. In other words, whether the production of Medical Technologists is higher or lower than the current level depends on the government policy to consider insurance finances. In this study, we assessed 'productivity scenario 3' based on the productivity as of 2012, when the government's policy direction was not considered. Based on the demand scenario using the ARIMA model, the supply of Medical Technologists is expected to be excessive. This oversupply accounts for less than 10% of the total and therefore should not be a big problem. However, given that the employment rate of Medical Technologists is 60%, it is necessary to consider policies to utilize the unemployed. These measures should expand the employment opportunities for the unemployed. To this end, it is necessary to strengthen the functions of laboratories in the public health center, to increase the quota of Medical Technologists, to assure their status, to establish a permanent inspection system for outpatient patients, and to expand the export of Medical Technologists overseas.

This study analyzes how workers become impoverished and have their jobs less stabilized after they suffer from non-job-related sickness. Given that South Korea lacks sickness benefits, which most of OECD member states legislate and implement except US and Switzerland, this study examines its impact on laborers' job stability and povertization in Korea. The researchers have conducted in-depth interviews with nine former or present laborers who have the experiences and four experts on the issue in July-September, 2017 for the qualitative analysis. It is found that laborers, after becoming aware of their sickness, at first endure their pain without informing their employers not to lose their jobs. The attititude is observed especially among non-standard laborers, because sickness more often leads to job loss for them than for standard laborers. After workers have to leave their jobs due to their sickness in the end, they have no choice but to keep working in less stable jobs to compensate for income losses. They become gradually impoverished with their social capital like family bond declining. We observe laborers who are eligible for industrial accident insurance compensation could not benefit from the system because some employers refrain from the legal reporting duty. Due to this illegal practices, some industrial accident victims unduly lose their jobs due to "non-job-related sickness". Second, some employers report to the authority that their sick laborers have left their jobs 'voluntarily' even when they have quitted it without their volition, in which case the newly unemployed are not eligible for unemployment benefits. Large holes in Korea's safety nets for those suffering from multiple risks of sickness and unemployment.

Satellite-derived data is collected by observing the Earth and is used in various fields such as national defense, natural disasters, location-based services, infrastructure, environment, energy, marine, and insurance. This study aims to present the virtuous cycle structure of the satellite information data industry and the business ecosystem model of the industry. As a research method, cases were collected and categorized from the following areas: literature, online, application, and content. The results show that the ecosystem model of the satellite information data industry provides an approach to content services in public and commercial areas, and develops various algorithmic technologies to facilitate content production and services at the level of complex general-purpose technologies. Second, in terms of content typology, satellite information data can be subdivided into monitoring content, urban space monitoring content, and satellite information content. Third, the consumption value of satellite content could be subdivided into informational value, environmental, social and governance (ESG) value, educational value, and content value. In order to expand the global content market, Korea will need to focus on creating an ecosystem for the satellite information industry and discovering differentiated content. It will also need to increase the popularization and accessibility of data to the general public and promote the Korean K-Satellite Information Data Industry ecosystem through government support, policy efforts, and policies such as establishing legal systems, increasing investment, and training human resources.

The Purpose of this study is to present the basic data for selecting and improving the safety education contents which help practically middle school students through analysis of contents of safety education in 'field of home life' of 2009 revised middle school textbooks. The subjects of analysis are 12 types of middle school textbooks: in total 24 books written by 12 publishers in terms of the revised curriculum in 2009. The analysis criteria is developed by the researcher referring to preceding studies regarding safety education based on the seventh safety education standard presented by the Ministry of Education (2015). With such analysis criteria, all words related to the contents of the safety education of analysis criteria were extracted from each textbook, such as words directly mentioned as 'safety', words mean as 'psychological safety' and 'happy life', words related to 'attention', 'note', 'stability' etc. Under the analytic frame of safety education contents according to a home economics textbook, content analysis method was used for producing the frequency and percent of those words. The textbook analysis shows that the number of pages regarding safety education is 336.3 pages, as 9.8% in total 3,412 pages of 12 types of technology and home economics textbooks. As following the analysis of each textbook volume of the proportion in the contents related to safety education, 224.9 pages are on the first volume and 111.9 pages are on the second volume. As grades increase from year one to year three, the proportion of safety education in home economics textbooks is decreased. The highest number of safety education contents unit is 'Self-management of youth' which includes three parts of safety education. In the case of a unit for emphasizing practice, experience and practical exercise such as 'Life of youth' and 'Practice of eco-living', safety education content in the area of 'life safety' are mostly contained. Safety accidents related to the most student experienced, Household accidents (1.4%) and experiment or practice accidents (0.3%) are presented in a low figure. The contents of universal housing and school violence are duplicated on first and second volume of text. The most presented safety education content in the 12 types of textbooks are proper sexual attitude, dietary problems, family conflict and food choice. The least common contents are dangerous drugs, family welfare, internet addiction and industrial accident compensation insurance. As this study is to analyze 12 textbooks developed in 2009 revision curriculum, it is necessary to compare it with the textbook written by the revised curriculum in 2015 and to clarify the contents system of safety education and to avoid duplication of contents. In addition, it is necessary to develop and distribute a safety education program that can support textbooks.

Purpose: The purpose of this study is comparison of clinical outcomes in ACL reconstruction between auto-hamstring tendon and allo-tibialis anterior tendon. Materials and Methods: In this prospective study, we included 60 subjects who underwent ACL reconstruction using 30 hamstring autograft(mainly, national health insurance) and 30 tibialis anterior allograft(including MVA and industrial injuries) between May 2003 and June 2005 by a single surgeon, with a minimum follow-up of 12 months. Outcome measurements were the range of motion, the Lachman test, the IKDC score, the Lysholm score, KT-1000 arthrometer and one-leg hop test. Results: For all the cases, the range of motion was above 135 degrees. The Lachman test, KT-1000 arthrometer and one-leg hop test showed no significant difference between two groups. The IKDC score of auto-hamstring group($87.840{\pm}2.106$) was significantly higher than that of allo-tibialis anterior group($85.273{\pm}2.782$). The Lysholm score of auto-hamstring group($88.067{\pm}2.586$) was also significantly higher than that of allo-tibialis anterior group($85.300{\pm}3.030$). Conclusion: The results of ACL reconstruction using the auto-hamstring tendon and allo-tibialis anterior tendon showed no significant difference in objective items but auto-hamstring group showed better results in subjective scoring. This difference may result from individual factors such as economic problem, secondary gain.

Background: Thoracic trauma is one of the leading causes of morbidity and mortality in developing countries. A rib fracture that is secondary to blunt thoracic trauma is an important indicator of the severity of the trauma. The purpose of study was to determine the morbidity and mortality rates and the management of rib fractures. Material and Method: We performed a retrospective study that involved all the blunt trauma patients with rib fractures, excluding those that were transferred to other hospital within 3 days, that were seen at our hospital between May 2002 and December 2008. Of the 474 admitted patients, 454 met the inclusion criteria. There were 356 male and 98 females, and their overall mean age was 53 years (range: 5~90 years). The outcome parameters included the mechanism of injury, the number of fractured ribs, the length of stay in the ICU, the Injury Severity Score (ISS), the length of the hospital stay, the pulmonary complications and the mortality. Result: The mechanism of trauma included traffic accidents in 189 (41.7%) cases, slipping down in 103 (22.7%) cases, falls in 85 (18.7%) cases, cultivator accidents in 30 (6.6%) cases, industrial accidents in 32 (7.0%) cases and assault in 15 (3.3%) cases. Intrathoracic injury was noted such as hemothorax in 269 (59.3%) cases, pneumothorax in 144 (31.7%) cases, pulmonary contusion in 95 (20.9%) cases, subcutaneous emphysema in 29 (6.4%) cases and great vessel injury in 5 (0.1%) cases. Conservative treatment was administered to most of the patients. Tube thoracostomy was administered in 234 (51.5%) cases, whereas thoracotomy was performed in 18 (4.0%) cases. The mean duration of thoracostomy was $5.2{\pm}6.2$ days. Most of the cases with rib fracture were treated in wards and their mean duration of hospital stay was $22.5{\pm}20$ days. The mean Injury Severity Score (ISS) was $14.8{\pm}10.9$ (range: 3~75). The mortality rate was calculated to be 4.8% (n=22). The main factors correlated with an adverse outcome were the number of ribs fractured, the duration of thoracostomy and pulmonary disease. Industrial insurance affected the length of hospitalization. Pulmonary contusion and the Injury Severity Score (ISS) affected the mortality. Conclusion: Rib fractures are a indicator of severe injury. Because of the complication and associated injuries, we believe these patients should be admitted for evaluation and treatment. Recent studies on the impact of rib fractures after blunt trauma have shown that patients as young as 40 years of age demonstrate increased morbidity and mortality with similar injuries as compared to that of older patients. The ISS and pulmonary contusion influenced the mortality rate. Patients with isolated rib fractures should be hospitalized if the number of fractured ribs is one or more.

Background: Pneumoconiosis, like other chronic respiratory diseases, is essentially incurable and, for many, progressive. While improved survival time is an important aim of treatment, there is growing recognition that for some people, improving the quality of life is more important than extending the length of life. Currently the measurement of the quality of life is used to assess the efficacy of therapeutic agents. Methods: Sixty-three pnemoconiotics who were admitted to St. Mary's Hospital between April and August 1999 were interviewed using COOP charts, Chronic Respiratory Questionnaire(CRQ) and Pneumoconiotic Respiratory Questionnaire(PRQ), a newly developed questionnaire concerning clinical and socioeconomic features of pneumoconiotics. Also, ILO classification of the chest film, pulmonary function test, and arterial blood gas analysis of the patients were evaluated. The scores between Industrial Accident Compensation Insurance(IACI) covered and uncovered patients and between clinically stable and unstable patients were compared. Results: Domains of CRQ and PRQ showed a high internal consistency reliability($\alpha$=0.86-0.89, 0.77-0.81) except the dyspnea domain($\alpha$=0.63) of CRQ. The scores on the CRQ and PRQ showed statistically significant correlations with the results of COOP charts, pulmonary function test and arterial blood gas analysis. The dyspnea domain and social activity domain of the PRQ showed significant difference between IACI covered and uncovered patients and between clinically stable and unstable patients. Conclusion : Korean translation of the Chronic Respiratory Questionnaire and the newly developed Pneumoconiotic Respiratory Questionnaire are reliable and valid methods and are likely to be useful in measuring the quality of life in patients with the chronic respiratory disease including pneumoconiosis.
