Objective : Bell's palsy is common and has many clinic study. but bell's palsy prognosis is not enough specific. So this study was evaluated bell's palsy prognosis, treatment number, sequela of normal group and bad prognosis group. Methods : From June 2009 to June 2010, patients who visited Dong-seo Oriental Medicine ENT. A clinic study was done on patient who were diagnosed bell's palsy, onset 2weeks within when first visited OPD and treated 3 times over in Dong-seo Oriental Medicine Cental. To evaluate grade of paralysis, House-Brackman Scale was used. We classified treatment numbers of each HB-Scale group, normal gIVroup and bad prognosis group. Results : The distribution of Onset HB-Scale : Gr II 26.25%, Gr III 67.5%, Gr IV 6.25% Onset HB-Scale Gr II patients completely recover 100% Onset HB-Scale Gr III patients completely recover 64.8%, improved 27.8%, nothing change 7.4% Onset HB-Scale Gr IV patients completely recover 40%, improved 60% Onset HB-Scale Gr II & IV patients recovery percentage make no difference of normal group (Group A) and bad prognosis. Onset HB-Scale Gr III patients completely recover Group A 66.7%, Group B 52.9%, improved Group A 23.2%, Group 35.3%, noting change Group A 5.1%, Group B 11.8% Onset HB-Scale Gr II patients has no sequela. Onset HB-Scale Gr III & IV patients has tendency that they treat more times, more improving and less sequela probability Conclusion : Onset HB-Scale is the indicator of acute bell's palsy prognosis.

무선센서네트워크는 위험 지역에서의 데이터 수집 용도로 최근 각광받고 있는 기술이다. 하지만 위험한 지역에서는 다수 노드들에서 동시 다발적인 장애발생 위험이 크기 때문에 대규모의 장애를 빠르게 복구시키기 위한 자가 복구 능력을 높여야 한다. 기존의 라우팅 프로토콜들은 하나의 노드에서 발생한 장애는 빠르게 복구하지만 다수의 노드들에서 장애 발생시 이에 효과적으로 대처하지 못한다. 이에 본 논문에서는 대규모 장애 발생시 이를 빠르게 복구하기 위한LSFA(Large Scale Failure Adaptive Routing Protocol)을 제안한다. LSFA는 다수의 노드들에 장애가 발생하여 데이터 전송이 이루어지지 못하는 환경에서 장애를 빠르게 감지하고 라우팅 주기를 적응적으로 조절하여 빠른 시간에 네트워크를 복구한다. LSFA는 패킷손실 정도를 장애발생 판단의 기준으로 사용하며 장애를 감지하면 라우팅 주기를 짧게 하여 장애가 발생한 사실이 네트워크에 빠르게 퍼지도록 한다. 베이스스테이션으로의 경로를 유지하고 있는 노드가 주위에 장애가 발생한 사실을 감지하면 자신의 라우팅 정보를 빠르게 전파시켜 장애 복구가 빠르게 이루어지도록 한다. 실험을 통하여 LSFA가 다른 프로토콜들에 비해 적은 패킷을 사용하면서도 장애를 빠르게 복구함을 보인다.

This study is to review the Joseon government's attempt to recover the tariff autonomy lost in the course of entering into the unequal treaty with then-Japan government, as well as the practical effort to realize such an attempt. Among other attempts, the Joseon government ① began imposing tariffs starting September 1878 by establishing Dumopo Customs Office in Busan, ② dispatched on April 1881 a group of investigators to the competent authorities to review and look back the Joseon's tariff system against Japan and ③ entered into a tariff negotiation with then-Japan government on September 1881 with the emissary (Susinsa) Byeong-ho Jo representing the Joseon government. A series of these attempts, in line with each other, represents the Joseon government's ceaseless, constant effort to recover the tariff autonomy, which is what this study intends to review from the modern-day perspectives. Authored by Byeong-ho Jo to capture an advantageous position in the 1881's tariff negotiation against then-Japan government, 「Joilseui」 successfully represented the Joseon government's position on matters of ① the Japanese tax-autonomous district in Korea, ② defining tariff rates, ③ use of Japanese Yen for payment of tariffs, ④ effective period of the treaty and ⑤ export restrictions on grains. Failure of the Joseon government's attempt to recover the Tariff autonomy was attributable not only to, as 「Joilseui」 defined, ① governments' non-cooperative attitudes on the negotiation table, ② lack of authorities that the entrusted bodies had, ③ import tariffs defined high and ④ export restrictions on grains and red ginseng, but also to loss of the tariff autonomy in 1876 and the 1881's negotiation broken down that were plotted by then-Japan government's invasive policy.

We propose a new multipath-based reliable routing protocol on MANETs, Multipath-based Reliable routing protocol with Fast-Recovery of failures (MRFR). For reliable message transmission, MRFR tries to find the most reliable path between a source and a destination considering the end-to-end packet reception reliability of the routes. The established path consists of a primary path that is used to transmit messages, and the secondary paths that are used to recover the path when detecting failures on the primary path. After establishing the path, the source transmits messages through the primary path. If a node detects a link failure during message transmission, it can recover the path locally by switching from the primary to the secondary path. By allowing the intermediate nodes to locally recover the route failure, the proposed protocol can handle the dynamic topological change of the MANETs efficiently. The simulation result using the QualNet simulator shows that the MRFR protocol performs better than other protocols in terms of the end-to-end message delivery ratio and fault-tolerance capability.

The building that supply tidal and splash zone was constructed near Seamangeum Gate Bridge. The specimens that will be tested for maintenance of gate bridge were exposed on the tidal and splash zone, totally about 650. The characteristics of strength, salt penetration profile, field application of surface repair material and section recover material will be acquired by periodical test. The program was developed to obtain optimal maintenance strategy of gate bridge as a marine concrete structure and to deposit experimental data, lab. test result, field test result, on its D/B. On this paper, the comparison of concrete and recover material in the salt penetration characteristics was expressed. The quantitative analysis of salt contents in concrete surface was most important so the improvement for the machine of gathering power of concrete and the apparatus of measuring chloride contents was proceeded at this time. The two conclusions were summarized like as - The resistance of chloride attack of concrete was appeared 2.5 times bigger than that of recover material - The resistance of chloride attack of polymer series was appeared more higher than that of others.

The purpose of this study was to investigate the changes of muscle power by transcutaneous electrical nerve stimulation(TBNS), low frequency-low intensity(20pps, invisible muscle contraction intensity), low frequency-high intensity(20pps, visible muscle contraction), high frequency-low intensity(100pps, invisible muscle contraction intensity) and high frequency-high intensity(100pps, visible muscle contraction). The results were as follows. 1. Increased muscle power after 30 minutes of treatment by low frequency-low intensity TENS, and post-treatment 30 minutes muscle power were increased more than pre-treatment power(p<0.05). 2. Decreased muscle power after a 30 minute treatment by low frequency-high intensity TENS, and after the 30 minute treatment was terminated muscle power didn't recover to pre-treatment levels. 3. Decreased muscle power after 30 minute treatment by high frequency-low intensity TENS, but post-treatment 30 minute, muscle power didn't recover to pre-treatment levels. 4. The muscle power was remarkably decreased by high frequency-high intensity TENS after 30 minute treatment, in addition treatment terminated after 30minutes didn,t recover to pre-treatment power(p<0.05). 5. Lower frequency-low intensity TENS are good methods for preventing muscle fatigue, buty high intensity (TENS) are increased muscle fatigue. 6. Traditional TENS by high frequency-low intensity is a good method for preventing muscle fatigue.

A new method is presented to recover missing deformation data of lateral walls of foundation pit when the monitoring is interrupted; the method is called Dynamic Mathematical Model - Parameter Interpolation. The deformation of lateral walls of foundation pit is mainly affected by the type of supporting structure and the situation of constraints, therefore, this paper mainly studies the two different kinds of variation law of deep horizontal displacement when the lateral walls are constrained or not, proposes two dynamic curve models of normal distribution type and logarithmic type, deals with model parameters by interpolating and obtains the parameters of missing data, then missing monitoring data could be Figured out by these parameters. Compared with the result from the common average method which is used to recover missing data, in the upper 2/3 of the inclinometer tube, the result by using this method is closer to the actual monitoring data, in the lower 1/3 part of the inclinometer tube, the result from the common average method is closer to the actual monitoring data.

Objectives: To examine the opinions regarding recovery and assess their will to recover in outpatients with schizophrenia. Methods: Total 98 stable outpatients with schizophrenia were enrolled. To investigate the outpatients' opinions regarding recovery, we asked the subjects to write down the ways they could think they had recovered from their current disease. We classified their answers and chose final 39 statements. Using this questionnaire, they were asked to what extent they agreed with each statement. Moreover, the Recovery Assessment Scale (RAS) was used to measure the subjects' will to recover. Results: Many of the 39 subjects who were surveyed about their opinions on recovery agreed on 11 statements about taking medicine, social life, daily life, social functioning, positivity about life (happiness, hope, confidence, and tranquility), symptoms, occupation, and self-control. The RAS score showed a significant correlation with age (r=-0.26, p<0.01), age at onset (r=0.26, p<0.01), duration of illness (r=-0.52, p<0.01), and number of hospitalization (r=-0.46, p<0.01). Conclusion: This study shows that positivity about life is an important part of the patients' subjective recovery criteria in schizophrenia. Therefore, if clinicians pay more attention to this part of subjective recovery, it would strengthen the patients' will for recovery.
