The average injury rate in sawmilling industry for the last 5 years is 4.99%, which means that more than 200 injuries have occurred in that industry every year. Because the first step in risk assessment is the hazard identification, it is very important to know how to define the hazard and nature of harm. We analyzed 643 accident records of three years(2010-2012) and carried out site survey for the same cases. As a result, the most common types of work at the time of injury in sawmilling industry were removing jammed wood 81(12.8%), wood carrying task 52(8.1%), wood cutting 49(7.6%), travelling table log band saw 41(6.4%), maintenance 37(5.8%) etc. In addition, there were statistically significant differences in some analysis factors such as injured body parts, employment size, and handling material among different working places. Therefore, it is concluded that differentiated prevention efforts are necessary in each workplace.

Despite over eighty percent of industrial accidents were caused by unsafe behaviors, most safety programs still focus on changing workers’ internal status such as thinking and attitude rather than directly changing safe related behaviors. The purpose of this paper is to introduce the basic concepts and procedures of Behavior-Based Safety (BBS) which originated in applied behavior science (ABS), BBS attempts to change safety related behaviors by manipulating antecedents and consequences of workers’ behaviors. Also this paper introduces several case studies conducted globally in various industrial fields. These case studies highlight the procedures of BBS, their impacts on safety performance and accidents rate, and other business results. Based on these results, this paper proposes new guidelines for safety management.

Sickness absence is one of the most important indicators for worker's health and occupational safety and health performance. Sickness absence is primarily depended upon sickness but psycho-social factors in workplace may moderate sickness absence. Even though worker is falling into illness, sickness absence can be prevented by job satisfaction. In Korea it is very difficult to find research output about the association of sickness absence with job satisfaction. This study is planned to investigate the effect of job satisfaction on sickness absence. The third Korean Working Conditions Survey done by Occupational Safety and Health Research Institute in 2011 was used to anlayze by logistic regression analysis. The result has shown that job satisfaction has statistically significant effect on sickness absence and simultaneously diminish the effect of symptoms experience on sickness absence. The effect of job satisfaction is greater in short term sickness absence that in long term sickness absence. This study has some limitation because of the cross sectional data of Korean Working Conditions Survey. In future, sophisticated statistical analysis may be done with modelling.

Risk information may be one of the most important factor for worker's safe behavior because that safe behavior can be oriented by attitude based on risk information. Traditionally KAP(knowledge, attitude and practice) model was useful frame for the change of human behavior. Knowledge is formed by information through experience and education. Worker's health may be prevented by his or her own active safe behavior based on risk information. This paper is to investigate the effect of labor union on the provirion of risk information by labor union. Data for analysis is the third Korean Working Conditions Survey done by Occupational Safety and Health Research Institute in 2011. The sample size is 50,032 economic active person surveyed by household interview survey with structure questionnaire by trained interviewer. The difference of risk information provision among employees was tested by mean difference test. The level of risk information of employees of companies with labor union is higher than that with non labour union. This paper has some implication for the promotion of safe behavior of employees through risk information provision mediated by labor union. Some limitation of this study may be considered because of using the cross sectional survey data.

In this study, mammography was conducted with Lorad Selenia from HOLOGIC. The phantoms used were Female rando phantom from THE PHANTOM LABORATORY and ACR phantom from GAMMEX RMI. The dosimeters used were the glass dosimeter reader FDG1000 and PLD from CHIYODA TECHNOL. The shielding used to compare and determine the amount of scattered ray in this study were lead shielding gear with a thickness of 0.25mm from INFAB and a customized bismuth shielding with a thickness of 0.2mm(2 layers of 0.1mm). The conditions were 28kVp, 65mAs for CC view and 30kVp, 85mAs for MLO view. The exposure dose by scattered ray were measured from thyroid, breast on the opposite side and gonad (hereafter called critical organs) without any shieldings for the first experiment, then measured four times each with lead shielding for the next experiment, and measured four times each with bismuth shielding for the third experiment. The average dose for each critical organ without shieldings were 135.75μGy, 649.67μGy and 546.25μGy, With lead shielding, the numbers were 0μGy, 63μGy and 1.5μGy, and 6.25μGy, 12.25μGy and 26.5μGy with bismuth shielding. Therefore, the lead and bismuth shielding have reduced 95.364% and 93.550% of exposure dose. Use of shielding s during mammography reduces the exposure dose on critical organs and other organs of the patient, and despite the similar shielding rate, the new shielding using bismuth is useful in shielding thyroid and gonad considering the mobility of the patient, light weight and thickness of the shielding.

The study was conducted from July 5th to 12th, 2014 on 30 males and females. The examination device used for this study were Discovery XR656(GE Healthcare, Kemath, Germany) DR and SOMATOM definition AS+ CT. T he device was made of foamex (foam PVC). The posture for cubital tunnel view examination requires for patients to bend their elbows more than 60 degrees and turn their forearms 20 degrees externally. The analysis method of cubital tunnel depth(CTD) was to measure the length between the deepest location of groove for ulnar nerve and a line vertical to the line connecting protruding part of medial epicondyle and trochlea medial in order to measure the CTD with and without the assistance device. CTD were measured and compared from VRT images on CT examination of 30 males and females to prove the usability of the assistance device. For statistics, SPSS 18.0 version was used to conduct independent two samples t-test. Differences in CTD between the two sexes were nonexistent but, the differences in CTD according to the use of assistance device were 4.63±0.86mm in temporizing measure, and 6.01±0.27mm with the assistance device for male. For females, the results were 4.58±0.41mm in temporizing measure and 5.94±0.58mm with the assistance device. The results proved that the measured values of CTD are deeper with the use of assistance device. The difference between CTD value from CT of normal person and CTD level measured with X-ray using the assistance device were nonexistent. P<0.05) Use of an assistance device made more accurate and convenient examinations possible compared to examinations without any assistance devices. Use of the assistance device in this study in radiological examinations on Cubital Tunnel Syndrome would provide more accurate and convenient examinations in the future.

The number of CT gradually tends to increase, but radiation exposure includes higher exposure dose of patients than other test methods as the rate of 67% in the whole radiology tests. Exposure dose of patients has increased due to it and the second exposure has been done by scattered rays of other organs except for test sites. Especially, special shielding has not been done in gonad which is very sensitive to radiation in brain and chest CT. So this study tries to research the second exposure dose of the gonad and how to shield it in Chest CT which does not include it. It was intended for 20 male adults who are 30 years old and conduct chest CT. SIEMENS’s SOMATOM DEFINITION AS* was used as CT equipment. For the scanning conditions, The tube voltage is 120kv, the tube current is 90mAs, and the slice thickness is 3mm as the general chest CT conditions. CHIYODA TECHNOL CORPORATION’s FGD1000 was used as Glass dosimeter (PLD). A lead pad of 0.25mmPb was produced as the shielding board. For the research method, the shielding rate was compared by measuring exposure dose of the gonad before and after shielding and the usefulness of the shielding board was evaluated. The average exposure dose of symphysis pubica before shielding was 280.5μGy and the average exposure dose of coccyx was measured as 151.5μGy. The average exposure dose of symphysis pubica after shielding the gonad with a lead pad of 0.25mmPb was 42μGy and the average exposure dose of coccyx was measured as 41μGy.

본 연구는 조영제를 사용하는 CT검사에서 조영제 부작용이 발생한 환자에 대한 정보를 수집하고 분석하여 조영제 부작용 발생인자들을 분석하여 조영제 부작용을 미리 예측하고 예방하여 조영제 부작용 발생빈도를 최소한으로 줄이고자 하며, 병원 내 약물부작용 관리 업무에 기초자료로 활용하여 병원의 진료 서비스의 향상과 영상의학과 종사자들의 업무 효율성을 증대시키고자 한다. 연구 대상은 대전광역시에 소재하는 4개의 종합병원에서 조 영제를 사용하는 CT 검사 중 만 18세 이상 남녀를 대상으로 2010년 1월부터 2014년 7월 까지 전산으로 기록되어진 4,932명 중 변수가 부족한 데이터를 제외하고 조영제 부작용이 발생한 환자 404명(이하 환자군)과 같은 기간 조영제 부작용이 발생되지 않은 환자에서 조영제 부작용이 발생한 환자의 성별, 조영제 종류를 교차하여 무작위 추출을 한 404명 (이하 대조군)을 대상으로 분석하였다. 기존에 알려진 위험 인자에 대해서 본 연구에서는 일반적 특성에 따른 조영제 부작용은 계절에 따른 특성에서 봄에 검사한 환자보다 겨울에 검사한 환자가 조영제 부작용 발생확률이 높게 나타나는 것으로 유의한 차이가 있었고, 다른 특성에서는 유의한 차이가 없었다. 조영제 부작용검사 관련 특성에서는 일반적인 검 사보다는 Dynamic 검사 시 조영제 부작용 발생확률이 높게 나타났고, 조영제 사용량이 130ml 이상 시, 주입속도가 4F/R 이상 시 조영제 부작용 발생확률이 높게 나타나는 것으 로 모든 특성들이 유의하게 차이가 나타남을 알 수 있었다. 계절적 변화에 따라 환자의 조영제 투입 시 세심한 주의가 필요하리라 생각되며, 매년 CT검사가 증가하고 있는 만큼 조영제 사용이 증가 할 것으로 예상되기 때문에 조영제 부작용의 일반적 특성뿐만 아니라 질병, 전처치, 심리적 요인, 기타 약물 복용, 등의 다양한 원인을 근거로 한 연구가 지속적 으로 진행되어야 하며 이러한 연구들을 통해 조영제 부작용의 발생 위험을 사전에 예방할 수 있는 체계적이고 효율적인 프로그램의 개발이 필요하리라 생각된다.

To solve the serious problem of insufficient manpower in medium and small scaled companies, our country allows introduction of foreign manpower for 5 business types such as manufacture industry, service industry, etc. and there are 226,825 people who entered by employment license system(E-9) in Sep. 2013. However, according to the results of investigation 「actual status and difficulties of foreign manpower's employment of medium and small scaled manufacturing companies」of KFTA in 2013, 36.4% of respondents responded that current scale of introducing foreign manpower is insufficient to solve difficulties of insufficient manpower in industrial world and 37.7% of them responded that the quarter of new employment is insufficient. So, they hope that current quarter system of foreign manpower can be abolished. Meanwhile, introduction scale of foreign manpower was decided by 53,000 people so as to solve enterprise difficulties in manpower and vitalize economics this year, but illegal aliens are 39,623, more than 17.5%, in Sep. 2013 after employment expiration. Therefore, it becomes serious social problem. Government displays various support businesses so that foreign workers after employment expiration can return to their homeland legally. This thesis intends to find measures to maintain royalty for our country and support their smooth resettlement through the analysis on homecoming support business of foreign workers.
