Female tollgate workers are known to be the most highly exposed to job stress in the service industry. However, there have been few studies on female tollgate workers. This study was thus performed to verify the mediator effect of work-family conflicts in the relationship between job stress and turnover intention of female tollgate workers. A survey was carried out in May, 2016, and the final data were obtained from 183 female tollgate workers by quota sampling. The major result was that their job stress significantly influenced on turnover intention, and work-family conflicts between the two variables were partially mediated. On the basis of the outcomes, first, further studies are needed to develop customized supporting programs for the female tollgate workers; second, internal efforts, such as psychological and social support programs such as Employee Assistance Programs (EAPs), should be launched for the workers at the enterprise level; third, national attention must be paid to improve the work environments of female tollgate workers.

대기오염이 인체에 미치는 영향을 연구하기 위하여 오염의 농도가 지극히 심할 것으로 예측되는 고속도로 서울톨게이트에 근무하는 근로자 37명과 사무직 15명을 대상으로 혈액 및 요중 납함량과 요중 코프로포르피린을 정량하고 임파구 중 자매염색분체 교환빈도를 계산하여 인적특성에 따라 비교 검토하였다. 한편 대기오염의 정도를 파악하고자 1986년 4월부터 약 3개월에 걸쳐 아황산가스, 이산화질소, 일산화탄소, 부유분진, 납, 벤조파이렌 등 인체에 유해한 오염물질들을 톨게이트 근무자가 근무하는 위치의 공기 중에서 정량하였다. 이들 성적을 비교 검토한 바 다음과 같은 결론을 얻었다. 1. 톨게이트 내의 공기 중 이산화질소, 일산화탄소, 부유분진, 벤조파이렌, 납량 등이 서울시내 일반 대기보다 월등히 높았다. 2. 톨게이트 근로자의 혈중 납량, 요중 납 및 포프로포르린량, 그리고 임파구 내의 자매염색분체 교환빈도의 평균치가 사무직근로자보다 유의하고 높았다.

A large number of studies have indicated associations between the impairment of respiratory health and exposure to ambient air pollutants such as ozone (O$_3$) , nitrogen dioxide (NO$_2$) , sulfur dioxide(SO$_2$) , particulate matters (PM$\_$10/). To evaluate this associations, we used the pulmonary function tests (peak expiratory flow rate : PEFR) by mini-wright peak flow meter and counting neutrophils in the nasal lavage (NL) as biomarker. From 15 June to 16 July 1998, for the workers in the highway tollgates, PEFR and NL were measured three times daily and twice per week. and association between the level of air pollutants and PEFR and NL were analyzed using the multiple regression model and the poisson regression model respectively. The results indicated that the effects of all measured air pollutants (SO$_2$, NO$_2$, O$_3$, PM$\_$10/) were not significantly associated with the value of PEFR. On the other side, SO$_2$, NO$_2$, PM$\_$10/ were significantly associated with the number of neutrophils in NL. The increase in SO$_2$, NO$_2$of 10ppb and in PM$\_$10/ of 10$\mu\textrm{g}$/m$^3$was associated with 24%, 21%, 35% increases in neutrophil counts. But the ozone exposure was not associated with NL.

Objectives: This study was conducted in order to evaluate $PM_{10}$ concentrations at eight highway tollgate booths from July to September 2017. Methods: A total of 16 samples were collected from eight toll booths. Each $PM_{10}$ sample was collected using a 37 mm PTFE filter attached to a Personal Environment Monitor. Results: The geometric mean concentrations of $PM_{10}$ in the toll booths was $83.51{\mu}g/m^3$. The mean $PM_{10}$ concentrations measured on freight roadways were much higher than those of measured on general roadways($102.46{\mu}g/m^3$ and $68.05{\mu}g/m^3$, respectively). $PM_{10}$ was revealed to be higher in the morning($105.59{\mu}g/m^3$) than at dawn or in the afternoon($71.26{\mu}g/m^3$ and $61.22{\mu}g/m^3$, respectively). The mean $PM_{10}$ concentration in toll booths ventilated through an air conditioner was higher than that for those using a window or no ventilation. The rate of exceeding the Ministry of Environment Maintenance Limit($200{\mu}g/m^3$) was 6.25%, and the rate of exceeding the Ministry of Labor Recommended Limit($150{\mu}g/m^3$) was 12.5%. Conclusions: In order to protect the health of toll booth workers exposed to airborne dust, it is necessary to check the exposure level from indoor air quality on a regular basis and to manage it appropriately according to the results.
