OBJECTIVES: Social support was previously regarded as acting only a stress modifier, but many recent studies have found a direct effect on stress. The purpose of this study is to evaluate the role of social support on job stress and psychosocial stress to determine whether it acts via direct effect or indirect effect. METHODS: This study was performed in May 2003. The study population consisted of 425 male workers in an automobile factory in Korea. Data were collected with structured self-administered questionnaires. We used JCQ(Job Contents Questionnaires) to measure job stress and social support, and PWI-SF(Psychosocial Well-being Index-Short Form) to measure stress outcome. We analysed the relationships using Structural Equation Modeling software AMOS4. RESULTS: It was found that social support acts both as a direct stressor and an indirect stressor via job stress. However the direct effect was double the indirect effect. CONCLUSIONS: The direct effect of social support on stress was the more major. Therefore social support is an independent stressor rather than a stress modifier in automobile factory workers.

2.A Status of the Report for Industrial Injuries and Illnesses at an Automobile Related Plant .
Korean Journal of Occupational and Environmental Medicine 1998;10(4):562-570
The incidence rate of industrial accidents tends to decrease since 1984. It seems to be caused by the active prevention activities for industrial accidents, however, there has been some concern for under-reporting of industrial injuries and illnesses. This study was carried out to assess the status of injury occurrences and industrial accident reports. The author reviewed and analysed the record from an infirmary of an automobile related factory from May 1994 to April 1998. The results obtained were as follows; 1. The number of injuries were 665 spells during four years and incidence rates per year per 100 persons were 39.57(1995), 39.04(1996) and 36.86(1997). The incidence rate of industrial injuries that needed over four days of medical treatment were 4.32 %, 6.51 % and 4.90 %, respectively by the year. 2. The highest incidence rate by age was the 20-29 age group (46.30 %) and by working duration was the under five years group (46.18 %). 3. A total of 665 injuries were occurred by 244 workers. Workers who experienced over five accidents were 41 persons (16.8 %) with 285 injuries and the proportion of total spells was 42.9 %. 4. Workers who experienced over 5 accidents were the younger group, had under five years working duration and worked at the position of frequently using hand tools. 5. Among the 665 spells, the injuries that needed over four days of medical treatment were 93 spells (14.0 %) and the reported proportion as an industrial accident was 8.6 % (eight spells). The results suggest that improvement of the report system is required to enhance the accuracy and reliability of the industrial accident statistics, and analysing all accidents would be necessary to setup the strategy for prevention even if they are minor injuries.

Pneumocephalus is defined as the presence of air within the cranial cavity. Trauma such as automobile accidents, motorcycle accidents, and missile injuries is the most common cause of pneumocephalus. There have previously been four reported cases of pneumocephalus following stab wounds to the neck in the English literature. We present an unusual case of pneumocephalus following a neck stab wound with a review of the literatures.

Orbital fractures are increasing in frequency with the rise in number of automobile accidents and the development of industries. It may be difficult to detect fractures with plain X-rarys of the orbit, because of the superimposition of the shadow by bony structures. Even minor alterations in head position can cause a significant change of shadow. Computed tomography is extremely accurate and can be diagnostic with respect to the location and size of the fractures, because it provides detailed visualization of both the bones and soft tissues of the orbits. We studied 89 patients with orbital fractures proven by computed tomography and the results are as follows: 1. Orbital fractures occurred most frequently between the ages of 11 and 40 years. 2. The causes of orbital fractures were traffic accidents(46.1%), contact with human bodies(24.7%), fall-down injuries(14.6%) and others(14.6%). 3. There was no significant difference in the incidence of orbital fracture between the right and left eyes. 4. In single wall fractures, medial wall fractures were most common, followed by factures of inferior, superior and lateral walls in order. 5. In combined wall fractures, medial and inferior wall fractures were most common.

6.A Case of Reconstruction of Orbital Floor Fracture by Grafting Parietal Bone.
Journal of the Korean Ophthalmological Society 1987;28(1):209-215
An orbital floor fracture is caused by a sudden increase in the intraorbital pressure, resulting from the application of a traumatic force to the soft tissues of the orbit. The fracture is complicated by diplopia or enophthalmos. Orbital floor fractures are caused by the automobile accident, human fist or the ball. Our hospital performed reconstruction of an orbital floor fracture by grafting parietal bone on the fractured orbital floor area of the patient who visited our hospital 4 months after the hit on his left eye by a fist. We now report this case with the review of various aspects of an orbital floor fracture.

Traumatic diaphragmatic rupture is uncommon, but requires a prompt diagnosis and repair. Diaphragmatic injury is most commonly associated with automobile accidents. The diagnosis is difficult and may be delayed because there are no specific symptoms, signs, or radiographic studies that are pathognomic for diaphragmatic injury. The most important factor in the diagnosis is a high suspicion and the use of proper diagnostic studies. We report a case involving the delayed presentation of diaphragmatic rupture in a 54 year old man, requiring surgical repair 12 days following multiple blunt trauma. It should be noted that early recognition for diaphragmatic injury is important in patients with multiple trauma to avoid the potential fatal complications.

8.Current Status and Proposal of Drowsy Driving.
Journal of Sleep Medicine 2016;13(2):35-39
Drowsy driving is a major cause of automobile crashes which can lead to more serious injuries than other causes of traffic accidents. Here, we review the accumulated scientific evidences and legal decisions of drowsy driving in various countries. Also, we highlight recent institutional strategies and developing technologies for prevention of drowsy driving. To prevent drowsy driving, raising public awareness as well as collaboration of professionals in various fields are requisites.

OBJECTIVES: This study was conducted to investigate the job stress factors, psychosocial stress and their associations in workers engaged in the research and development of vehicles, and according to job role. METHODS: We recruited 4,066 subjects from workers at a research and development center of an automobile company. A total of 2,764 workers answered the questionnaire about socio-demographic factors, health behaviors, work-related factors, subjective labor intensity, KOSS, and SF-PWI. The final analysis included 2,282 male manufacturing and research workers. Univariate analyses and multiple logistic analyses were conducted on the complete questionnaire data to compare the job stress factors, psychosocial stress and their associations between research and manufacturing workers. RESULTS: The adjusted Odds ratios comparing the high risk group to the low risk group regarding PWI group were 2.23(95%CI=1.63-3.04) in "Lack of rewards", 1.64(95%CI=1.20-2.24) in "Interpersonal conflict", 1.59(95%CI=1.15- 2.20) in "Organizational injustice", 1.58(95%CI=1.17-2.14) in "Occupational climate" and 1.43(95%CI=1.05-1.94) in "Job insecurity" among research workers, and 2.46(95%CI=1.59 -3.80) in "Lack of rewards" and 1.94(95%CI=1.17-3.22) in "Organizational injustice" among manufacturing workers. CONCLUSIONS: There are differences in job stress factors between research and manufacturing workers. Further studies and discussions based on quantitative methodology for seeking more fundamental causes of these differences are required to establish job stress intervention plans and policies.

Traction injuries of the brachial plexus have recognized since the classic descriptions of Duchenne, Erb and Klumpke. The original cases resulted from birth injuries, presumably from traction forces. In recent years, automobile accidents have resulted in and increase in traction or closed injuries to the brachial plexus. This paper reviews our experiences with 3 cases of injuries characteristically demonstrated by Pantopaque myelography.
