As the autonomous motion control system of a vehicle becomes more sophisticated, the accurate predictions of tire forces, which are the key sources of vehicle motion, have become increasingly essential. In this paper, the lateral and vertical forces of the four-wheel tires were independently estimated by analyzing the resulting force and moment applied to the vehicle with respect to its motion, without using any a priori tire model. The proposed tire lateral force estimation logic is different from previous studies because it can identify independent forces on the left and on the right by appropriately compensating for nonlinearity caused by lateral load transfer and the influence of the initial toe angle. The proposed estimation logic was verified through experiments in various road surfaces and steering scenarios. The results of the experiments show that the proposed algorithms are viable in actual vehicle environments.

Background: To suggest potential of Korean medicine treatments as a conservative management for neurogenic claudication and lower extremity weakness due to spinal stenosis. Case Summary: The patient suffered weakness, pain and numbness of the right leg and difficulty walking with diagnosis of spinal stenosis due to herniated lumbar intervertebral disc. Korean medicine treatments, including herbal medicine, acupuncture, pharmacopuncture and Chuna manual therapy were applied. The Numeric Rating Scale (NRS) of pain and numbness in the right leg decreased from 7 to 4, with an increase in strength of the right leg from 60% to 95% compared to the strength of left leg. Walking duration also increased from less than one minute to more than five minutes. Conclusion: Korean medicine treatment may be considered as an effective conservative management for symptoms of spinal stenosis.

In emergency department, the clinicians occasionally meet some patients with toxicity caused by ingestion of unknown wild edible greens or herbal agents. Due to there was few quantitative or qualitative studies about the mechanism or clinical features of these materials, it' s hard to approach to the patients and start the initial management in emergency department. Authors experienced the case of poisoning by Scopolia Japonica ingestion. We report this case with review of Scopolia Japonica.

Objective: To compare recent domestic and overseas research trends about acupuncture therapies on migraines. Method: Case reports and randomized controlled trials were searched via Pubmed. Searches were limited to publications between 2012 and 2017. Results: Four case reports and twelve randomized controlled trials were searched from Pubmed. Research showed that acupuncture therapies are more significantly effective than other therapies, such as sham acupunctures and Western medicines. Conclusion: There has been more active overseas research about acupuncture therapies on migraine compared to domestic studies. To examine the efficacy and suitability of acupuncture therapies on Koreans with migraines, domestic studies and research should be conducted more actively.
