In order to investigate the working conditions related to cumulative trauma disorder(CTD) and symptoms of CTD, a survey was conducted covering 305 employees who were working in three furniture manufacturing companies in Kyungin area. Data were collected by using questionnaire of the Personal Ergonomics Profiles. The results were as follows : 1. The mean score of working conditions related to CTD was 0.95. The mean score of working conditions for labor workers were significantly higher than that of clerical workers. Among 4 factors of working conditions, the higher score were shown in the working and environment factors with 1.22 and 1.18, respectively. 2. Symptom prevalence rate of CTD for workers was $81.0\%\;{;}\;82.9\%$ for labor workers and $77.0\%$ for clerical workers. As for symptom of CTD in body part, higher rate were shown in lower back with $50.2\%$, shoulder and neck with $38.4\%\;and\;36.4\%$ respectively. 3. The score of symptom severity of CTD were 3.45. Significant difference was shown in symptom severity of forearm and wrist/hand part between labor and clerical workers. As for symptom severity of CTD in body part the higher score were shown in shoulder, ankle/foot, forearm. lower leg and elbow. and the highest score for labor workers were shoulder and ankle/foot and for clerical workers was lower back. 4. As a whole, symptom of CTD for workers positively correlated to working conditions. 5. Symptom of CTD for workers seemed to be significantly influenced by working factor, sex, working duration and working area factor.

The purpose of this study is to examine the demographic, economic, and psychological factors that influence the quality of life (QoL) of the elderly. The data in the 'Survey on the Elderly in 2011', were collected from The Ministry of Health & Welfare and the Korea Institute for Health and Social Affairs. The samples included 3,312 out of the total of 15,146 elderly people aged from 65 to 70 years. Multiple regression analysis and path analysis were used to analyze the research model. The findings are as follows. First, the most critical factor that affected the QoL of the elderly was "subjective standard of living" with other factors including "subjective physical condition level", "depression", "total annual income", "the number of chronic disease", "self-esteem", "economic supports from their adult children", "education level", "living with their adult children or not", "sex", and "home ownership", in that order. Second, based on the path analysis results, the QoL of the elderly was influenced by "subjective physical condition level", "subjective standard of living", "depression", "self-esteem", "total annual income", "education level", and "the number of chronic disease", in that order. In particular, "depression" had a negative direct effect and an indirect effect on the QoL of the elderly, whereas "self-esteem" had a positive direct effect and indirect effect on their QoL. Third, "labor force participation status" did not affect the QoL of the elderly. However, it implied the mediating effect of "self-esteem" and "depression" on their QoL. These results show that demographic, economic, and psychological factors heavily influence the QoL of the elderly. Specifically, "depression" and "self-esteem" turn out to be mediating variables that strongly influence the QoL of the elderly. Also, "labor force participation status" does not have a positive direct effect on the QoL of the elderly but has a positive mediating effect of "depression" and "self-esteem" on their QoL.

Membrane system has been increasingly considered as a safe and cost-effective water treatment process especially in case of small scale water works. This research is a basis of membrane application in water works through a long period test with obtaining operation skills and evaluation of water quality and cost competitiveness. For the research, the UF membrane system was installed in small water treatment plant that uses river-bed water as raw water. The system was consisted of 2 stage membrane and operated in constant flow mode (Flux: 1.5, 1.0, 0.9, 0.6). In each different flux condition, TMP trends were showed better results at lower flux condition. And through the high flux condition test, it is certified that membrane system could deal with breakdown of one stage. Water quality of permeate was satisfied the water quality standards especially turbidity. To know what mainly causes fouling on membrane, the test by membrane with several cleaning agents and EDX analysis have done in lab. Through the tests, ferrous concentration in raw water, backwashing water and membrane surface etc. was high and it causes fouling inside and outside of membrane. So acid cleaning using organic acid such as oxalic acid is necessary in Chemical in Place (CIP). At the economical aspect the electrical cost of membrane system is higher than that of slow sand filtration but labor cost can be reduced by automation. However, the use of labor should be determined considering effectiveness and stability of operation. Because during the operation, there are several breakdown such as electrical shock by lightning, water drop in summer, etc.

Job satisfaction related elements consist of wage level, job stability, working condition, career development, and communication. Design/methodology/approach - For the data collection, this research made use of The Korean Panel Survey of Employment for people with disabilities, with the study period consisting of 2016-2018, and the number of observations measuring 4405. For the data analysis, the ordinary least square, fixed effect, and random effect regression models were used. Findings - The results indicate that the life satisfaction of people with disabilities is positively influenced by wage satisfaction, job stability satisfaction, working condition satisfaction, career development satisfaction, and communication satisfaction. Research implications or Originality - This study informs policy makers for the design of welfare for people with disability, specifically related to their labor conditions.

우리나라의 농촌에서는 산업화와 밀접히 연관되면서 시설작물의 재배가 증가해 왔고, 특히 1970년대 이후에는 대도시 주변지역에서 급격히 증가해 왔다. 개별농가의 영농유형은 농업노동력의 양보다는 질적 수준과 관련이 있으며, 노동력의 질적 수준에서는 특히 경영주의 연령이 중요하다. 경영규모는 경영주의 연령과 관련이 있으며 미작 재배농가보다는 시설작물 재배농가의 경영주 평균연령이 더 젊고 경영규모가 더 크다. 시설작물 재배의 주목적은 영농을 통한 상업성의 제고가 가장 원인이지만 부족한 노동력 때문에 경영규모에는 한계가 있고 특히 농산물 가격의 불안정과 수익성 악화는 적극적인 경영규모 확대를 제한하고 있다. 시설작물 재배농가의 경영규모 확대는 농지의 매입보다 임차지의 확대를 통해 이루어지며, 이때 영농조건이 유리한 농지를 중심으로 임대차가 발생된다. 결과적으로 대도시 근교 농촌지역의 유지와 발전을 위해서는 영농의 상업화와 수익성 제가 중요한 요인이지만 토지이용의 효율성 측면에서는 농지의 자연적 조건이 중요하게 작용된다. 그러나 농외부문의 취업기반이나 교육시설의 보완 없이는 촌락 공동체의 유지측면에서 가족 구성원의 분리문제와 농업노동력 부족문제가 해결될 가능성이 낮다.

본 연구는 안동지역 삼베수공업산지의 존립기반 즉 생산유통체계의 변화 및 경영특성, 그리고 산지내 사회적 분업과 지역 분화의 실태를 분석하였다. 안동 삼베수공업은 1970년대 고도경제성장기의 극심한 쇠퇴기를 거쳐 1980년대 후반 이후 소득수준 향상에 따라 1970년대 초반 수준으로 회복되면서 일정수준을 유지하고 있다. 생산유통체계는 종래 일괄생산체계의 "소상품형"에서 1980년대 후반 이후 품질 및 생산공정 개선노력과 생산연령층의 노령화 그리고 기존 제품판매체계의 기능약화로 생산공정상의 사회적 분업을 중심으로 생산유통체계가 변화하였다. 산지내 사회적 분업은 대마 재배와 제사 및 직조 공정간, 나아가서 부분적인 수공업적 공정상의 분업 그리고 생산과 제품 판매간의 크게 3부분에 걸쳐 이루어지고 있다. 이중에서 강산과 제품의 유통 판매간의 분업은 활성화되지 못해 신제품의 기획 개발 및 판로개척을 선도할 수 있는 업체가 정착 발달하지 못하고 있다. 지역 분화의 특징으로는 과거 전지역에서 보편적으로 이루어지던 생산이 특정 지역에 한정적으로 이루어 곁과 동시에 지역간 생산유통체계상의 차별성에 기초하여 지역간 연계가 강화되었다는 점을 들 수 있다. 지역분화의 원인으로는 대마재배의 지역 특화와 노동력 이용방식에 있어서의 차별성을 들 수 있다.

이 논문은 우리나라 중소기업의 해외진출을 위한 전용산업단지 조성을 전제로 주요 국가들에 대한 산업입지결정변수를 적용하고 이에 따른 비교우위결과를 분석 한 것이다. 연구결과, 첫째, 2010년 1/4분기 현재, 우리기업이 진출한 국가들은 모두 128개국이며, 이 중 '80년~2010년 동안의 총 신고건수 기준 상위 20개국은 중국, 베트남, 일본, 홍콩 등 아시아 지역에 속한 국가가 13개로 가장 많았다. 둘째, 해외산업단지 조성을 위한 주요 분석대상국을 선정하였다. 128개 국가 중에서 1인당 GDP가 우리나라 보다 낮고, 2007년~2010년 동안 현지 법인 신고건수가 10건 이상인 38개 국가를 선별하였고, 이 중 2008~2009년 기준 월 최저임금이 우리나라와 유사한 수준(815달러/월)의 10개 국가를 제외하여, 최종적으로 중국, 베트남, 캄보디아 등 총 28개국을 주요 분석대상국가로 선정하였다. 셋째, 해외산업단지 조성시 국가별 비교우위 평가지표를 크게 투자유인정책, 노동시장 유연성, 시장수요 잠재력, 인구규모, 제조업 신고건수 변화율 등 5개 부문으로 구분하고, 부문별로 세부지표를 선정한 후 중요도에 따라 가중치를 부여하였다. 넷째, 28개 국가를 대상으로 평가지표를 적용한 바, 노동시장 유연성과 투자유인정책 부문의 평가점수가 높고 상대적으로 미개척된 지역으로서 우리나라와 우호 관계에 있는 인도네시아, 몽골, 우즈베키스탄 등이 전반적인 비교우위가 높은 것으로 나타났다.

There are insufficient models that find problems and solutions for accident prevention through risk assessment and suggest safe work process and work instruction from foundation works to finish work for accident decrease. This paper presents a quantitative risk assessment model by analysis of risk factors in each process such as foundation, erection, structure, equipment finish and etc based on accident examples and investigation on actual condition in building. In addition, the safety management system was developed to perform risk assessment of construction and use it for effective safety training for labor.
