연구배경: CWP은 주로 석탄 분진을 흡입함으로써 발생하는 폐 실질의 병변으로 단순 흉부 방사선 소견상 폐 결절의 기준을 1cm로 하여 SP과 PMF으로 구분한다. PMF의 경우 환기 능력의 장애가 심하고 조기사망율이 증가하고 있으나 모든 광부에서 PMF이 발생하는 것은 아니여서 이러한 CWP의 발생에 관여하는 요인을 찾기 위한 많은 연구가 있어왔다. 본 연구의 주목적은 진폐증 환자에서 질환의 심한 정도를 ILO 분류에 따라 SP, PMF으로 구분한 후 감염이나 기타 기저 질환이 없는 상태에서의 혈중 면역 글로블린 농도를 흡연력과 연령에 의한 면역 글로불린의 변화를 고려한 후 진폐증의 심한 정도와 혈청면역 글로불린 농도와의 연관성을 관찰하기 위하여 시행하였다. 방 법: 태백 중앙 병원과 영동 병원의 진폐증 환자중 정밀 검사를 시행하기 위해 병원을 내원한 SP 환자 51명과 입원중이거나 정밀검사를 시행한 PMF 환자 59명을 대상으로 하였고 대조군은 진폐증 환자와 나이, 성별 및 흡연 병력이 적합하면서 진폐에 노출된 병력이 전혀 없는 주변 아파트 경비원과 병원내 지원자 58명을 대상으로 하였다. 면역 글로불린의 검사(IgA, IgG, IgM)는 독일 Behring사에서 제조한 각 각의 Kit를 사용하여 Nephelometer 분석기(Behring Nephelometer : Germany)를 사용하여 측정하여 대조군 57명, SP 51명, PMF 49명의 면역 글로불린을 측정하였다. 결 과: 본 연구에서 대조군의 나이에 따른 혈청 면역 글로불린의 변화는 나이가 증가 할수록 IgG는 의의 있게 증가 하였고 흡연력에 의한 면역 글로불린의 차이는 없었다. 대조군, SP, PMF사이의 혈중 면역 글로불린의 농도간에는 차이가 없었으나 흡연력과 나이의 영향을 고려한 다중회귀 분석에서 IgG의 농도는 대조군과 비교하여 SP 환자군에서 통계학적으로 의미 있게 감소하였고 PMF환자군에서는 감소하는 경향이 있었다. 폐기능 검사의 중증도와 면역 글로불린 농도사이에는 관련이 없었다. 결 론: 흡연력과 연령을 고려한 상태에서 진폐증 환자의 혈청 면역 글로불린의 농도는 대조군과 비교하여 SP 환자군에서 IgG의 농도가 감소하였으며 PMF 환자군에서도 감소하는 경향을 나타내어 진폐증과 IgG사이에 연관성이 있다고 생각되며 폐기능 검사의 중증도와 면역 글로불린과는 관련이 없다고 생각된다. 향후에 CWP의 발생 및 진행 기전을 이해하기 위해서 많은 수의 진폐증 환자를 대상으로 하는 전향적 연구와 함께 염증세포 및 싸이토카인의 역할에 대한 연구가 필요할 것으로 생각된다.

Objective : Walking with a Material handling is an activity frequently undertaken by agricultural workers in Korea, due to the nature of their work. This study aimed to investigate differences in biomechanical variables according to the mechanical alignment of the lower limbs when walking with a heavy load, and to use this as basic data in the design of various working environments to reduce the skeletomuscular burden on the knee joint. Method : The study subjects comprised of 22 right-foot dominant adult men and women aged between 20 and 23 years. The subjects were divided into a varus or valgus group according to the mechanical alignment of the lower limb by using radiographic findings. The subjects walked without any load and with a load of 10%, 20%, or 30% of their body weight held in front of them. The Kwon3d XP program was used to calculate biomechanical variables. Results : The flexion/extension moment of the knee joint showed a decreasing trend with increased load, irrespective of the mechanical alignment of the lower limb, while the varus group did not show normal compensatory action when supported by one leg at the point of maximum vertical ground reaction force. In addition, in terms of the time taken, subjects showed no difficulties in one-foot support time up to 20%/BW, but at 30%/BW, despite individual differences, there was an increase in single limb. The increased load resulted in a decrease in the ratio of standing phase to ensure physical stability. The valgus group showed a trend of increasing the stability of their center of mass with increasing load, through higher braking power in the early standing phase. Conclusion : In conclusion, although there was no statistical difference in biomechanical variables according to the mechanical alignment of the lower limbs, the varus group showed a more irregular walking pattern with a Material handling than the valgus group, partially proving the association between lower limb alignment and walking with a Material handling.

A questionaire developed by the researcher to obtain subject's general characteristics, main symptoms, medical examination, diagnosed disease was used as the tool for the study. The researcher analyzed the data with SPSS PC/sup +/ program. : the distribution of the subject's general characteristics and main symptoms was described with percentages and the difference between main symptoms and screening tests analyzed with X²-test, t-test, ANOVA. The result of this study are as follows : 1. For the distribution of diagnosis in males. liver disease was most frequent and hypertension was second : in females, hypertention and liver disease were not common in that order. 2. The most common complaints were indigestion in the digestive system, sputum in the respiratory system, irregular heart beat in the cardiovascular system, frequent urine in the urinary system vertigo in the hematologic system. 3. The main symptoms according to sex were for females, a statistically siguificant higher rate of complaints in the digestive system, cardiovascular system, urinary system, hematologic system, musculoskeletal, mental & nervous system as compared to males. 4. The main symptoms according to age were that in the the second decade there wara higher rate of complaints in the digestive system, and cardiovascular system than in the older age groups : and in the fifth decade more in the musculoskeletal system. 5. The main symptoms according to occupation were that formers and fishers had a higher rate of complaints in the mental and nervous system as compared to other occupation groups : and office workers, in gynecology. 6. The main symptoms according to diagnosis, were symptoms of the digestive system, frequent in liver disease : symptoms of the cardiovascular system in allergic disease. 7. The screening tests which showed the highest rates were UGI /FGS, PFT : In males a higher rate of abnormality was seen in abdominal ultrasono- graphy and in, females, in mammography. 8. In screening tests according to sex, males showed a higher positive rate for chest X-rays, and LFT, and females, in mammography, pap smear, CBC. 9. In screening tests according to age, higher positive rates of obesity, high blood pressure, chest X-ray, mammography, pap smear, FBS, CBC, urine test were seen in the fifth decade : PFT and abdominal ultrasonography in the third decade. The subjects who wanted comprehensive health check-up were not asymptomatic but had an illness with several symptoms. It is found that the most frequent diagnosed diseases were hypertention and liver disease. So proper observations must be done for them. Comprehensive health check-ups should be changed to a comprehensive examination including treatment beyond examination for those subjects with positive results.

콘크리트 표면에 발생된 균열은 구조물의 수명에 영향을 미치는 주요원인으로 작용하기 때문에 주기적인 검사와 유지관리가 필요하다. 콘크리트 표면 유지관리를 위한 실링작업은 표면에 발생된 균열을 초기에 보수하는 방법으로 시간 경과에 따른 균열의 추가생성 및 확산을 방지하는데 효과적이다. 하지만, 교량 하부의 실링작업은 열악한 작업환경으로 인하여 작업자들의 안전성 확보에 문제가 있다. 이런 이유로, 콘크리트 구조물의 유지관리를 위한 실링자동화의 필요성이 부각되고 있다. 본 논문은 콘크리트 교량 하부에 발생된 균열의 실링작업에 로봇을 적용하기 위한 두 가지 제어방법에 대하여 제안한다. 하나는, 균열의 궤적을 자동으로 추적하는 방법이다. 로봇은 카메라로부터 취득되는 영상정보로 균열의 궤적을 파악하는데, 이전 시점의 궤적 정보를 통하여 다음 이동할 시점의 정보를 유추할 수 있다면, 실시간으로 변동되는 궤적 정보에 대응이 가능하면서 자동으로 균열을 추적할 수 있다. 다른 하나는 접촉면에 일정한 힘을 유지하여 실링하는 방법이다. 장기간 외부 환경에 노출된 거친 표면에서도 로봇이 일정한 접촉력을 유지하며 실링작업을 수행한다면, 균등한 완성도를 유지할 수 있다. 이러한 균일한 힘의 유지를 위하여 임피던스를 이용한 힘 제어 기법을 제안한다. 본 논문에서는 실링 로봇에 적용하기 위하여 개발한 두 가지 제어기법들을 소개하고, 그것을 적용한 Lab Test와 Field Test를 수행한다. 이 시험결과를 토대로 로봇의 현장적용에 대한 의견을 제시한다.

It is necessary for managing a perfect process for degasing aluminum molten metal according to the increase of a grade of aluminum and its alloy products. There are some methods that have been used to manage a degasing process in recent years, such as an injection method that uses aluminum molten metal powder and chemicals supplier and input method that supplies argon and nitrogen, or chlorine gas by using a gas blow-tube. However, these methods show some problems, and it shows that it is a difficult process to handle. pollution due to the producing a lot of toxic gases like chlorine and fluoride gas. irregular effects, and lowering work efficiency due to the excessive processing time. The problems that are the most fatal are the producing a lot of sludge due to the reaction of aluminum molten metal with chemicals. loss of metals, and decreasing the life of refractory materials. In order to solve these problems. this paper develops a technology that is related to aluminum continuous casting molten metal and monolithic degasing apparatus. A degasing apparatus developed in this study improved the exist ing methods and prevented environmental pollution wi th smokeless. odor less, and harmlessness by using a new method that applies argon and nitrogen gas in which the methods used in the West and Japan are eliminated. The developed method can significantly reduce product faults that are caused by the production of gas and oxidation because it uses a preprocessed molten metal with chemicals. In addition. the amount of the produced sludge can also be reduced by 60-80% maximum compared with the existing methods. Then. it makes it possible to minimize the loss of metals. Moreover. the molten metal processing and settling time is also shortened by comparing it with the existing methods that are applied by using chemicals. In addition, it does much to improve the workers' health, safety and environment because there is no pollution. The improvement of productivity and prevent ion effects of disaster from the results of the development can be summarized as follows. It will contribute to the process rationalization because it does not have any unnecessary processes that the molten metal will be moved to an agitator by using a ladle and returned to process for degasing like the existing process due to the monolithic configuration. There are no floating impurities due to the oxidation caused by the contact with the air as same as the existing process. In addition. it can protect the blending of precipitation impurities. Because it has a monolithic configuration. it can avoid the use of additional energy to compensate the temperature decreasing about 60t that is caused by the moving of molten metal. It is not necessary to invest an extra facilities in order to discharge the gas generated from a degasing process by using an agitator. The working environment can be improved by the hospitable air in the factory because the molten metal is almost not exposed in the interior of the area.

사회서비스는 서구 자본주의 국가를 중심으로 높은 실업과 복지에 대한 국가지출 축소 등의 문제에 대응하고 성장과 분배의 선순환 구조를 이룩하기 위해 일자리창출정책과 연계되어 논의가 시작되었다. 특히 사회서비스는 여성노동력이 비교우위를 기대할 수 있는 분야이고 비교적 괜찮은 일자리라는 점에서 주목받고 있다. 양질의 사회서비스 제공과 지속가능한 일자리 창출을 목표로 하는 사회적기업은 여성친화성이 높아 여성일자리의 새로운 대안으로 기능할 수 있다. 이에 본 연구는 사회적기업이 실제 여성에게 괜찮은 일자리를 제공하고 있는지를 살펴보았다. 사회적기업 491개소 전체를 대상으로 한 조직수준 분석에서는 종단분석을 통해 사회적기업에서의 여성 참여율, 조직내 지위와 안정성, 임금수준 등에 대해 성별 비교분석을 하였다. 사회적기업 종사자 830명을 대상으로 한 개인수준 분석에서는 횡단분석을 통해 사회적기업 진입이전 상태를 비롯하여 일자리 만족도와 일자리 지속희망도에 대해 성별 비교분석을 하였다. 분석 결과, 사회적기업에서 여성의 비중은 70% 수준이며 특히 40대 이상 중장년층과 취약계층 여성의 참여가 높은 편이었다. 여성의 임금수준은 남성의 85~95% 수준으로 일반기업체와 비교할 때 임금격차가 거의 없는 일자리로 나타났다. 그러나 사회적기업에서 여성 일자리는 업종을 불문하고 비정규직과 비관리직에 집중되어 있었다. 이는 여성의 경력단절과 직업경험 부족 등에서 기인한 것으로 보인다. 사회적기업 여성근로자, 특히 취약계층 여성일수록 현재의 일자리를 지속하고자 욕구가 강한 것으로 나타났다. 조직수준 및 개인수준 분석 결과를 종합해 볼 때, 사회적기업은 괜찮은 여성일자리를 제공하고 있는 것으로 볼 수 있다. 그러나 향후 사회적기업 여성근로자의 고용안정성을 높여 여성의 경력이 유지 개발될 수 있도록 하고 여성 개인의 역량 향상이 사회적기업 경쟁력으로 연계되도록 방안을 마련할 필요가 있다.

Recently, a long strike by hospital labor union emerged as a serious social issue. During the Worldcup Games in June, 2002, labor strikes broke up at 'C', 'K' and other hospitals, and in 2007, 'Y' hospital suffered much from a strike. Such series of extreme labor disputes have awakened people of importance of a more stable labor-management relationship for the medical institutions responsible for people's health than any other business organization. The purpose of this study was to examine the labor-management disputes at 'Y' hospital in 2007 and 'C' and 'K' hospitals in 2002. The results of this study can be summarized as follows; First, requests of the labor union such as pay raise, reemployment of the irregular workers as regular employees and participation of the labor union in personnel affairs are the long-held or core issues suffered by the medical institutions. Such issues are not independent from each other but complicated with each other surrounding the pay raise. Accordingly, it is not easy to determine the genuine bone of issue for labor-management disputes. Second, the model type of disputes between labor and management at medical institutions may be strike. However, it is conceived that the type of disputes would be subject to change as the essential medical service area system began to be operated since 2008. Third, the common characteristic of the labor strike among the 3 sample hospitals was occupation of the hospital lobby for a sit-in strike to maximize the negative effects of strike. Article 42 (Prohibition of Violence) of Labor Union and Labor Relation Coordination Act prohibits occupation of production or other important business facilities. In addition, since Ministry of Labor interprets that the hospital lobby belongs to the important business facilities enumerated by Article 42 of the above act, occupation of the hospital lobby for a sit-in strike may be too controversial to be admitted as a fair act of labor dispute when its legitimacy should be judged. Fourth, the counter-measures taken by the hospitals against the strike were observance of the principle 'no labor no pay,' closure, legal action, accusation, claim for recovery of damage, provisional seizure, disciplinary punishment, etc., but the principle of 'no labor, no pay' was not applied in a fair manner by 'C' and 'K' hospitals. However, 'Y' hospital applied this principle thoroughly to the strike; the hospital conduced to correction of the wrong labor-management relationship by refusing inclusion in the labor collective agreement of a provision about payment of wage during the period of strike or labor union's request to that effect during a strike. In addition, 'Y' hospital took an effective measure to end the strike earlier by notifying the labor union of cancellation of the collective agreement and banning the unionists from entering the hospital.

A study on the factors affecting subjective symptoms of labor working in textile industries was carried out from June I to 30 in 1991. A total of 870 laborers were selected from the textile industries at Taegu, Kyungbuk in Korea. The purpose of this study was to determine the factors affecting subjective symptoms and improve the health condition of the labor in the industries. The results of this study can be summarized as follows: 1. 72.5% of the respondents were females and 27.5% were males. 45% of them were in the age group of between 20 and 29 years old, 25.7% were between 10 and 19 years old and 14.4% were between 30 and 39 years old. 57.6% finished high school level education, 70.6% were single, 31.2% had religion of Buddhism and 57.3% lived in the dormitory. Financially, 45% of them partially supported their family members. 2. 34.5% of the respondants were working in the administrative areas and the rest were working in the production areas. The period of working was 1~4 years. 64.7% of them owned their houses. 72.9% worked for a shift. 15.9% were satisfied with their job and 17.1% were not satisfied with their job. 3. 44.0% of the respondants complained about eye problems and more females than males complained about problems. 4. The laborers in the age group of between 40 and 49 years old complained about serious headache and younger laborers complained about respiratory problems. 5. 50% of unmarried laborers complained about eye problems, 40% of night workers felt aches in their empty stomach. 6. 54.4% of the respondents working in manufacturing department complained about eye problems, 29.5% of working in processing department complained about headache and 43.4% of the respondents working in spinning department complained about shoulder ache. 7. Most laborers went to the drug stores for their health. 8. 60.7% of teen ages complained about their irregular menstruation. 51.7% of the in twenties complained about pain during the period. 45.8% of the respondents in thirties complained about nervous system. The women working nights show 74.1% in all three and highest complaint rate. According to the conclusion of this study, it is recommended that more money should be spent on better health education for the laborers in textile industries. Also it is recommended that the policies and supports for them should be strengthened.
