In this paper, a method for providing musics in vehicle user's bio-rhythm is proposed. The proposed method is a method to select and play musics automatically suitable for the user's emotion. Experimental results confirmed that the proposed method could provide better satisfaction to the users (drivers) compared to the methods given randomly.

Reactive oxygen species(ROS) are produced at a high rate continuously as a by-product of aerobic metabolism. Several lines of evidence provided that ROS appears to cause to develop aging and various diseases. High level of hyaluronic acid with decreased molecular weight has been detected in patients with inflammatory diseases including rheumatoid arthritis. Hyaluronidase is an endohexosaminidase that initiates the degradation of hyaluronic acid with high molecular weight. Prunus persica Batsch var. davidiana Maximowicz has been known as a korean folk medicine for treatment of neuritis and rheumatism. (omitted)

Essential oils extracted or purified from various plants have shown various beneficial effects. Seed parts of Schizandra chinensis Baillon (Schisandrae Semen) have been used as a traditional medicine for thousands of years in parts of Asia, including Korea, China, and Japan. However, the pharmacological mechanisms of essential oils purified from S. fructus (S. chinensis Baillon) remain largely unresolved. The aim of this study was to investigate the safety of Schisandrae Semen essential oil (SSeo) by a single- dose toxicity study in mice. SSeo was orally administered at a dose of 5,000 mg/kg in ICR mice. All animals were sacrificed after 14 days of treatment. After a single administration, mortality, clinical signs, body weight changes, and gross pathological findings were observed for 14 days. We also measured parameters of organ weight, clinical chemistry, and hematology. No toxicological change related to the test substance or mortality was observed after administration of a single oral dose of SSeo. There were no adverse effects on clinical signs, body weight, or organ weight and no gross pathological findings in any treatment group. The clinical chemistry and hematological parameters were within the normal ranges except total bilirubin. Therefore, the approximate lethal dose for oral administration of SSeo in mice was considered to be over 5,000 mg/kg. The results on the single-dose toxicity of SSeo indicate that it is not possible to reach oral dose levels related to death or dose levels with any harmful side effects.

In this study, Green apple from Mungyeong area was used as material in the fermentation process. In apple fruit growing process, to produce a high quality apple fruit, some Green apple should be removed. Since the removed Green apple fruit is inedible, it doesn't have any economical value. To solve this problem, this paper proposed fermentation process to increase the economical value of raw apple as a fermentation product. This research conducted seven days, and the pH and brix value analysis was done every 12 hours during fermentation process. The experimental results show that the fermentation product under blender treatment is better than cutting treatment and without cutting treatment. Initial brix 25% is the best treatment for fermentation because produce fermentation product with a good taste and aroma than other treatment.
