Palldium(Ⅱ) 촉매 하에서의 말단 알릴 디올의 고리 카보네이트와 아세토니드의 산화반응은 anti-Markovnikov hydation에 의해 알데히드 또는 α,β-불포화 알데히드 만이 생성되었다. 치환된 알릴 디올의 분자내 이중 결합의 반응으로는 (E)-알릴 디올의 경우에 β-케토 생성물을, 반면에 (Z)-알릴디올의 경우엔 α-케토 생성물을 얻을 수 있었다. 치환된 알릴 디올의 고리 카보네이트와 아세토니드에서는 각각 β-케토 화합물과 α,β-케토 화합물 들이 생성되었다. Palladium(Ⅱ)-Catalyzed oxidation of acetonides or cyclic carbonates of terminal allylic diols afforded aldehydes or α,β-unsaturated aldehydes as the sole products, resulting of anti-Markovnikov hydation. For the internal olefins of the substituted allylic diols, (E)-allylic diol provied β-keto-product, whereas (Z)-allylic diol affored α-keto-product. The acetonides and cyclic carbonates of the substituted allylic diols yielded β-keto-products and α,β-unsaturated ketones, respectively.

목적 : 우리는 신체를 근막의 통합된 전체로 보는 근막이완요법과 TrP를 파괴하는 전침요법을 기능성 척추측만증에 적용시킬수 있는지 알아보았다. 방법 : 22세의 기능성 척추측만증을 가진 남성에게 다양한 형태의 근막이완요법을 적용하였고, 중둔근, 요방형근, 슬괵근에 전침요법을 적용하였다. 결과 : 3주시술후 다리길이차이, 근막구축, Cobb's 각과 척추회전변위가 감소되었고 흉부압박감 같은 전신적증상이 호전되었다. 결론 : 근막이완요법과 전침병행치료가 신체를 근막의 일체로 보는 관점으로 인체의 구조적불균형을 바로 잡아줄수 있는 새로운 치료법의 기능성을 찾았다. Objective: We investigated this study in order to see the adaptation capability of myofascial release that translating the body being integrated fascial totality and electroacupuncture treatment that breaking trigger points in functional scoliosis. Methods: We applied myofascial relase by three patterns and electroacupuncture in TrPs of gluteus medius, Quadratus lumborum and Hamstring muscle to 22 year-old who have had functional scoliosis. Results: After 3 weeks, The leg length, fascial restriction. Cobb's angle and rotation scoliosis are decreased. Systemic symptoms, for example; chest discomfort are improved. conclusion: Myofascial release and electroacupuncture treatment is new methods that treating the sturctural unbalance in view of body's fascial network.

Objectives: Although there have been several reports that described characteristics for young age stroke, information regarding very young age (18–30 years old) has been limited. We aimed to analyze demographic factors, stroke subtype, and 3-month outcome in acute ischemic stroke patient who have relatively very young age in multicenter stroke registry. Methods: We evaluated all 122 (7.1%) consecutive acute ischemic stroke (within 7 days after symptom onset) patients aged 18 to 30 from 17,144 patients who registered in multicenter prospective stroke registry, 1997 to 2012. Etiology was classified by Trial of Org 10172 in Acute Stroke Treatment criteria. Stroke severity was defined as National Institutes of Health Stroke Scale (NIHSS) and stroke outcome was defined by modified Rankin scale (mRS) at 3 months after index stroke. Results: The mean age of all included patients was 25.1±3.7 years and 76 patients (62.2%) were male. The median NIHSS at admission was 4. Considering stroke subtype, 37 patients (30.3%) had stroke of other determined etiology (SOD), 37 (30.3%) had undetermined negative evaluation (UN) and 31 (25.4%) had cardioembolism (CE) were frequently noted. After adjusting age, sex and variables which had P<0.1 in univariable analysis (NIHSS and stroke subtype), CE stroke subtype (odds ratio, 4.68; 95% confidence interval, 1.42–15.48; P=0.011) were significantly associated with poor functional outcome (mRS≥3). Conclusion: In very young age ischemic stroke patients, SOD and UN stroke subtype were most common and CE stroke subtype was independently associated with poor discharge outcome.

Abstract - In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance victor routing) with QoS(quality of service) support. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS guarantee between end point is a very important issue. The existing AODV routing protocol is implemented to use only BE (Best Effort) service. However, actual wireless mobile environment requires to reduce a waste of communication resources and meet with the real-time change of data paths by setting up routes with QoS support, considering available communication resources at each node in advance. Therefore, in this thesis, we propose an adaptive QoS support method using hello message in order to rapidly meet with the change of available communication resources and to smoothly perform route maintenance. For performance evaluation, we analyzed the average date reception rate. At that time, we used evaluation parameters such as node's mobility -stop time, hello message period, and packet priority, considering the node's mobility and the number of best effort/QoS data flows. As results, we found that with our proposed method the average data reception rate was increased 16.3% for 0 mobility-stop second case and 4.7% for 300 mobility-stop second case.

Abstract - In this thesis, we propose a QoS supporting method on wireless ad hoc-based active network for improving reliability. On the loss of route path, the existing DSR routing protocol has several problems with wireless network communication because of decease of data reception rate and increase of network load. The proposed method improves reliability of data transfer by using functions of active network. That is, by using functions of active nodes and active packets, the proposed method supports QoS with reservation transfer method that saves data packets on transfer at intermediate nodes with lost path and then re-transmit the packets after route reconfiguration.
