Background: As self-employed workers are vulnerable to health problems, this study aimed to analyze mental health problems and sleep disturbances among self-employed workers compared with paid workers in Korea. Methods: A total of 34,750 workers (23,938 paid workers and 10,812 self-employed workers) were analyzed from the fifth Korean Working Condition Survey, which included 50,205 households collected by stratified sampling in 2017. To compare mental health problems and sleep disturbance among self-employed workers and paid workers, multivariate logistic regression analyses were performed. Results: The odds ratio in self-employed workers compared with paid workers was 1.25 (95% confidence interval [CI]: 1.09-1.42) for anxiety, 1.11 (95% CI: 1.04-1.17) for overall fatigue, 1.11 (95% CI: 1.04-1.20) for difficulty falling asleep, 1.10 (95% CI: 1.02-1.18) for difficulty maintaining sleep and 1.24 (95% CI: 1.16-1.32) for extreme fatigue after waking up. Conclusions: Self-employed workers in Korea have a higher risk of self-reported mental health problems and sleep disturbances than paid workers. Further studies with a longitudinal design and structured evaluation are required to investigate the causal relationship between health problems and self-employment.

Irreducible traumatic knee dislocation is rare. The knee dislocation is classified depending on the incarcerated structures. Complete reduction is achieved by extracting the incarcerated structure. Several reports introduce the reduction of irreducible traumatic knee dislocation by open surgery or arthroscopy. This case describes irreducible posterolateral knee dislocation with interposition of the vastus medialis. Closed reduction failed in the emergency room, and complete reduction was attained by arthroscopically sectioning the muscle and fascia of the vastus medialis in the intercondylar notch.

Traumatic blunt aortic injury especially on proximal ascending aorta is a rare injury with a few reports. Generally emergency surgical management was performed. In this case, however, in multiple trauma with brain injury, emergency surgical management of aortic injury might result in unexpected secondary injury of the brain. Herein, we report a case of a 33-year-old man who was driving a truck was injured in a head-on collision. Evaluation revealed a pseudoaneurysm on his ascending aorta concomitant with epidural hemorrhage. He was treated by surgical management of his ascending aorta after 3 days from accident. There were no postoperative and neurologic complications and the patient was discharged after 18 days.

As the expension of metropolis and increasing of housing site, GIL(Gas Insulated Line) comes to the fore as an alternative to overhead transmission line avoided by local resident. The certification and experimental test for the GIL is now in progress in under ground test lab, Go-chang. For the test, we propose a method of PQ(pre-qualification) test which is essential for development and field application in this paper. The test following this method take about 200 days or 300 days under the circumstances.

Pelvic actinomyces, usually a complication of an intrauterine device, is uncommon and may present a diagnostic dilemma because of an atypical clinical presentation. This organism is very difficult to culture, and most actinomyces is actually identified by histologic feature in pathologic specimens. Authors have experienced a case of pelvic actinomycosis associated with an intrauterine device and reported with a review of literatures.
