본 연구의 목적은 선행연구의 이론에 근거하여, 노인의료복지시설의 원장리 더십이 요양보호사의 조직유효성에 미치는 영향을 살펴보고, 직무스트레스를 낮추는 방안을 모색하여 이를 바탕으로 요양보호사의 조직유효성을 증진하여 노인의료복지시설의 노인들을 질 케어 할 수 있는 방향을 제시하고자 하며, 본 연구에서는 원장리더십과 요양보호사의 조직유효성에서 직무스트레스의 인과관 계 구조를 연구모형으로 설정하고, 실증적으로 살펴봄으로 원장리더십과 요양 보호사의 조직유효성 관계에서 직무스트레스의 매개효과를 살펴보고 결과를 바 탕으로, 원장리더십과 요양보호사의 관계에서 조직유효성을 향상하기 위한 실 증적 기초자료 제공과 실천적 방안 마련을 목적으로 한다.

This study was performed to investigate the distribution of indoor air pollutants in medical facility in Gyeonggi-do area from February to November, 2012, and to conduct the health risk assessment from obtained data. PM10, CO₂, formaldehyde, CO, and total bacteria count(TBC) did not exceed the maintained standards, but mean concentration of TVOC was 402.3 ㎍/㎥ and thirteen of them exceeded the recommended standard. In the concentration distribution of pollutants for the monthly samples, CO₂, formaldehyde, TVOC, TBC were the highest level in August. From the factor analysis of indoor air pollution provided three factors; the first factor was seasonal factor (indoor temperature and humidity, TBC and formaldehyde), the second factor was ventilation factor (CO₂, PM10 and CO), and the third factor was building(or interior) factor (TVOCs). In the health risk assessment results, the excess carcinogenesis of formaldehyde for resonable maximum exposure worker was 1.21×10-⁴ which means exceeding the cancer criteria(1.0×10-⁴). We confirmed the probability of health effect caused by TVOC. The lifetime excess cancer risk of carcinogens(benzene, formaldehyde) and hazard quotient of non-carcinogens(toluene, ethylbenzene, xylene, styrene), and risk of regulation substances(PM10, CO₂) were safety level for inpatients and out patients.
