Taxi drivers are exposed to vehicular exhaust aerosols which are a mar source of atmospheric lead pollution in Korea where lead additives are incorporated in petrol. To investigate the blood lead concentration, their correlation factors and influences on taxi drivers, samples were collected from 90 taxi drivers who were living in the Taegu City, during August, 1989. Blood lead concentration was estimated by the atomic absorption spectrophotometer (IL.551) equipped with flameless furnace atomizer (IL.665). The results were analyzed statistically and compared with control group selected urban population. The mean blood lead concentration of taxi drivers and control group were $26.34{\pm}6.53{mu}g/dl\;and\;20.77{\pm}4.80{\mu}g/dl$ respectively (p<0.01). No significant correlation was observed between the blood lead concentration of taxi drivers and driver career (r=0.093). There were no difference of statistical significance in the blood lead concentration of smokers and nonsmokers.

Purpose : The objective of this study was to investigate the differences of hippocampal volume and shape as well as the functional change between long life experienced taxi drivers and controls of Korean population. Materials and Methods: Three-dimensional T1-weighted images and blood oxygen level dependent functional MRI(fMRI) were obtained from 8 subjects, consisting of 4 experienced (20-30 years) taxi drivers and 4 age-matched controls. The hippocampal volume and shape were analyzed with three-dimensional T1-weighted images. In addition, neuronal activities of brain were analyzed using a blood oxygen level dependent fMRI between the two groups. Results: The hippocampal volume showed no statistically significant difference between the two groups (p > 0.05). The left hippocampi of the taxi drivers were slightly elongated with larger head and tail portions than those of the controls (p < 0.05, uncorrected). For the functional MRI, fusiform gyrus was specifically activated in taxi drivers, compared with the control group. Conclusion: The structural and functional changes of taxi driver's hippocampus indicate the functional differentiation as a result of occupational dependence on spatial navigation. In other words, the continuous usage of spatial navigation performance may diminish degeneration of hippocampus and the related brain regions.

Purpose: This study was conducted to find out interrelation of health behavior and related variables to provide basic data for an effective health promotion for the taxi-divers. Methods: 293 male taxi-drivers from 2 cities in Korea participated in this study. The data were collected using questionnaires from April 17th to Jun 3rd, 2006, and analyzed by descriptive statistics, t-test, ANOVA, Pearson correlation, and multiple regression. Results: There were statistically significant differences according to monthly income, past illness or surgery, current disease or medication, frequency of fright on daily driving (FFDD), driving fatigue, working style, social support in health status; current disease or medication, FFDD, driving fatigue, duty shift, social support in health perception; body mass index (BMI), FFDD, driving fatigue, intention of changing job, social support in health behavior. Social support, health status, health perception, and health behavior were significantly correlated with one another. The multiple regression analysis showed that health perception (17.8%), BMI (6.8%), intention of changing job (5.7%), and driving fatigue (4.2%) explained the 34.5% variance of health behavior. And the 22.6% of variance of health perception was explained by social support (12.2%), health status (6.9%), and duty shift (3.2%). Conclusions: To promote the taxi-drivers' health, nursing intervention strategies unique for them should consider health behavior and affecting factors.

우리나라 택시의 경우, 이용측면에서나 수송분담률측면에서 볼 때 대중교통에 가까운 역할을 담당하고 있다고 할 수 있으나, 적정 택시대수를 산정하는 모형이 정립되지 않아 택시증차규모 결정시 이해관계자들의 마찰로 사회적 물의를 일으키며 이를 조정하는데 행정력이 낭비되고 있는 실정이다. 이에 본 연구에서는 택시 이용자와 업체 그리고 운전기사의 입장이 반영된 적정 실차율, 교통여건, 이용객수의 변화 들을 고려한 중소도시에서의 택시 증차대수 산정을 위한 합리적 기준이 제시되었으며 현재의 운행기록에 의한 거기기준실차율조사의 문제점을 개선한 새로운 택시 실차율 조사방법의 적용성이 검토되었다. 새로운 실차율 조사방법으로 부도심상의 주요 가로를 통과하는 택시에 대한 차량기준실차율을 조사하여 종래의 운전자의 운행기록표에 의한 거리기준 실차율과 비교하였다. 두 방법에 의한 실차율이 매우 근사한 값을 보였으며 통계적 검정에서도 차이가 없는 것으로 나타났다. 차량기준방법에 의한 실차율조사로 조사비용을 줄이고 자료의 신뢰성을 높일수 있을 것으로 기대된다.

Mobile application is growing explosively with the advent of a new technology: smartphones. Mobile application is a new marketing channel and performs as a start-up platform. This study examines the effect of mobile application on the off-line market. Despite the continuous declining demand for taxi service, paradoxically, the supply of taxi service has increased. The taxi industry can be categorized into general taxi and call taxi. General taxi is accidental and inefficient because it has to search for its own passenger. As call taxi takes the request of a passenger, it is more efficient than general taxi. However, the current defective passenger-taxi driver matching system and insufficient taxi driver management hinder the development of the call taxi market. Differences in differences (DID) is an econometrical methodology that examines whether or not an event has meaningful influence. This research uses DID to investigate the effect of the Kakao taxi application on the call taxi industry. Furthermore, it examines the effect of major companies' reckless diversification, which is considered unethical behavior. The passengers of call taxi data from August 2014 to July 2015 and those of designated driving service data of the same period were collected as the control group.

산업재해보상보험법(법률 제4826호) 4조 1항에 의하면 '업무상 재해라 함은 업무상의 사유에 의한 근로자의 부상, 질병, 신체장애 또는 사망을 말한다'로 규정되어 있습니다. 질병을 포함한 재해가 업무상 사유에 의한 것인가의 여부를 판단하는 것은 쉬운 일이 아니며 더욱이 국가의 사회적.경제적 여건에 따라 시대적으로 업무관련성의 범위나 인정기준등 개념이 변화되고 있기 때문에 산업보건분야 관련 종사자들은 관심을 갖고 항시 그 흐름을 파악하는 것이 바람직합니다. 본 란에서는 관계자 분들의 이해를 돕기 위해 근로복지공단에서 발행되는 '산재보험법판례속보'에 게재된 내용을 선별하여 업무상 재해 인정에 관한 최근의 법원 사례를 소개합니다.

The effect of dietary factors on the self-reported symptoms of fatigue were surveyed by the interviewing method among 119 taxi drivers in Cheonan area. It was shown that 86.5% of them were working over 11 hours a day and 34.4% of them over 16 hours. the level of job satisfaction was very low. Many of them felt fatigue during driving. Some symptoms of fatigue which many taxi drives said to be suffered from were headache physical exhaustion nervousness tired and sore eyes and anorexia. When related variables to the self-reported symptoms of fatigue were analyzed daily sleeping hours and exercise were significantly correlated with physical mental and neuro-motor fatigue, Subjects who had meals irregularly were greater than those who had regularly. In addition they tended to eat faster during working and 28.6% of them seldom had breakfast. Subjects who had meals irregularly consumed significantly less fat iron calcium vitamin A, and riboflavin. A and riboflavin and niacin than those who skipped it.

This study analyzed the differences of the person-environment fit, work stress and work satisfaction according to a demographic factors of elderly people under participation in job activities. And this study analyzed the relationship of the effects on person-environment fit, work stress and work satisfaction as well as the moderating effects of self-efficacy. The survey was conducted from February 15 to March 20, 2013 among the male taxi drivers aged 60 or older in the Seoul areas, and 358 responses were used in the data analysis. As a results, there were partially differences in the person-environment fit, work stress and work satisfaction according to a demographic factors. The person-environment fit had a negative impact on work stress, but it had a positive impact on work satisfaction. In addition, the self-efficacy had a moderating effects in the relationship of the person-organization fit and work stress.
