This study is purposed to explain the characteristics of injured workers' labor market situation and to analyze the factors influencing labor market transition of those workers. Using the Worker's Compensation Insurance Panel Data ver.1~3 which was surveyed by the Korean Workers' Compensation & Welfare Service in 2013-2015, this study analyzed 1,668 injured worker cases. The study shows that workers who have experience job retention at least once are 36.8% of all, 51.5% of them have experienced re-employment, and 36.9% have done unemployment. One result of the longitudinal analysis is that socio-demographic factors including gender, age, education years, convalescence period, ability on job performance, company size, term of service, temporary employment, daily-workers status before job accident and job training were associated with return to pre-injury job. The other result is that statistically significant factors affecting the probability to be the unemployed are gender, age, levels of disability, convalescence, ability on job performance, term of service before job accident, job rehabilitation service utilization. These findings indicate that we need to develop efficient intervention programs for supporting return-to-work and labor market transition of injured workers.

This study aims to investigate determinants that affect job retention of injured workers depending upon types of return to work in order to suggest define the intervention priority for those who returned to original works and for those who did not. After constructing explaining variables based on literature reviews, determinants were verified analyzing 1,292 people using Panel Study of Worker's Compensation Insurance(PSWCI) data. The job retention period turned out to be 46.6 months for those who returned to original work and 34.2 month for those who returned to new works. Injured workers who return to new works tend to have more unemployment experiences. As a result of Cox proportional regression analysis, the longer it takes to return to work, the longer both groups tend to retain after the accident. Age, recuperation period, health status, psycho-social rehabilitation, education and occupational training also affect on job retention probability for those who return to new work. Based upon the analyzed result, setting up an adequate duration for return-to-work, intervention for injured workers who experienced vulnerable working condition before the accident and continuous case management after return-to-work are suggested.

지난 10년간의 재해발새 현황을 분석해 보면 규모별로는 300인 미만 중·소규모 사업장에서 전체 재해자의 약 85%가 발생하였으며 특히 전체재해의 약 60% 정도가 50인미만의 소규모 사업장에서 발생하였다. 최근 국내의 가장 큰 경제위기 상황인 IMF 경제위기 이후 안전보건관리 기반이 취약해진 상황에서 최근의 경기회복으로 산업 가동률과 실질 근로 시간이 증가함으로써 산업재해 발생위험이 높아지고 있어 향후 1∼2년 간은 재해가 증가할 가능성이 크다. 그리고 현재 근로자 5인 이상 사업장에 대해서만 산업재해보상보헙법이 의무가입으로 되어있으나, 2000년 7월부터 5인 미만의 영세사업장에 대해서도 산재보험이 확대적용 됨으로써 산업안전보건 행정대상이 지금보다 사업장수는 10배, 근로자수는 50%이상 확대될 전망이다. 산재보험서비스가 5인 미만 사업장까지 확대되고 산업구조의 변화로 중·소규모 사업장 수가 증가될 것으로 전망되나, 중·소규모 사업장은 안전보건관리 능력이 부족해 재해자가 계속 증가하는 추세를 보이고 있으므로 산업재해 감소추세의 유지라는 전략목표의 달성 여부는 중소규모 사업장에 대한 안전보건관리에 달려 있다고 할 수 있다.

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.

Purpose: This study aimed to find the factors affecting medical sequelae management service satisfaction among injured workers. Method: This study population were 200 randomised samples of 619 medical sequelae management beneficiaries from April to June 2007 among occupational accident treatment ending workers in 2006. Data were collected through the telephone survey from November 28 to December 7 in 2007. Data were analyzed by ${\chi}^2$ test and multiple logistic regression using SAS 9.1 version. Results: According to the finding of this study, positive perceptions for the purpose and the effect of medical sequelae management were the factors influencing the satisfaction of medical sequelae management service. Conclusions: We recommend key issues to take into account for enhancing medical sequelae management service satisfaction in workers' compensation as follows; explaining the purpose and effect of medical sequelae management to client, evaluating medical sequelae management effect, and the policy participation of medical profession.

Purpose: The objective of this study was to evaluate long-term care needs using RAI MDS-HC and MI-CHOICE among the disabled workers. Methods: Data were obtained from 45 personal care recipients with the disability of mental and nervous system, and analyzed using SAS 9.1 by applying t-test, ${\chi}^2$ test, or fisher's exact test. Results: Only 'bed mobility' and 'indoor ambulation' items of ADL and problem activity were statistically significant factors by the level of personal care benefit. By MICHOICE grouping, 20.0 percent of subjects belonged to nursing home group, 51.5 percent were home care service, 28.9 percent were intermittent personal care. Conclusion: Personal care services in industrial accident compensation insurance have been categorized with two groups according to level of disability. But our results could contribute to provide personal care service according to the long term care needs.

Toprovide economical BISDN service, with which integration process of many types of media is possible, it is necessary to construct a system with ground network and satellite network combined. The method for this type of transmission using satellite is TDMA that can provide services to many users in various area. However, the most difficult task to connect TDMA which uses synchronous method to ATM which used asynchronous transfer mode is the deterioration n of ATM transmission quality such as cell delay variation. Therefore, it is necessary to develop delay variation compensation method which can confront to the ATM. Efficient ways to use satellite links under the conditions such that maximum efficiency of the delay variation is limited under the required value, and the burst characteristic of transmission cell does not increase are being researched for translation between in ATM and TDMA. This paper points out the problems when time stamp method, reviewd in ground network, is applied to the satellite links to compensate the delay variation .To solve the problem, discrete cell count method is introduced along with the calculation of transmission capacity and error rate.Also, from the observation of stab-ility of the system and verification of reliability even when singal error occurred in the cell transmission timing information, the proposed compensation method appeared to be excellent.
