Objectives: The aim of this study was to evaluate the effectiveness and safety of electroacupuncture for non-alcoholic fatty liver disease (NAFLD). Methods: A randomized, controlled pilot trial was conducted. Twenty-two participants were randomized into one of the two groups: an acupuncture group (n=11) and wait-list group (n=11). The treatment group received 8 sessions of electroacupuncture over 8 weeks. Twenty points (CV4, CV12, both LR14, GB26, ST25, ST34, ST40, ST36, SP4, SP6, LR3) were selected for needling. The control group did not receive acupuncture treatment during study period and followup were done in the 4th and 8th weeks after randomization in both groups. The primary outcome was body fat computed tomography and the secondary outcomes included blood test (aspartate aminotransferase, alanine transferase, triglyceride, total cholesterol, high density lipoproteincholesterol, low density lipoprotein-cholesterol, blood sugar test, ${\gamma}$-guanosine triphosphate) and body composition test (body mass index, weight, body fat mass, body fat rate, waist hip ratio). Safety was assessed at every visit. Results: There was no significant differences in between the experimental group and control group. There were no adverse events. Conclusions: The results suggest that In patients with NAFLD, electroacupuncture treatment did not induce worsening of liver disease and liver function, but it was no improvement symptoms of fatty liver. Study of herb medicine treatments and other acupuncture therapy of NAFLD are required later.

Even Faxian(法顯)'s Gaosengfaxianchuan (『高僧法顯傳』) and Iching(義淨)'s Nanhaijiguineifachuan (『南海寄歸內法傳』) are regarded as very important and useful documents to study the southeast asian buddhist culture, it is very difficult to grasp the contemporary state of those area because their descriptions are very brief and implicit. Therefore this essay aimed an in-depth reading their documents as original texts of modern understanding of those area, and tried to make a new views to approach the southeast asian buddhist culture by some more historically and concretely. At the early 5th century when Faxian(法顯) arrived, Buddhism was flourished in Sri Lanka. Because already a long time passed since the Saṇgha was schismatized into conservative and progressive at around the dominical year, he mentioned nothing about the conflict or disharmony of two orders. And the faith of Buddha tooth relic, which had been uprisen at 50 years ago from Faxian's visiting, was concretely established as a representative religion of Sri Lanka. According to his record, the carrying ritual of this Buddha tooth was performed very magnificently as similar with recent Korean Youngsan ceremony(靈山齋). In the mean time, it looks there were many sculptures of Buddha image made of precious stone of special product from Sri Lanka. The faith of Buddha-pāda(the Buddha's foot-prints) was also generalized at that time. The most famous monk of his contemporary Sir Lanka was Buddhaghosa, the author of Visuddhi-magga, but it is not sure that Faxian had met him. It can be suspected that the funeral in which Faxian participated could be belonged to him, or the Visuddhi-magga was writing at the peak during Faxian's staying. On the way to return to China, Faxian embarked an indigenous ship around Indonesia. It means there were no chinese trade ship which he can use. So the trade between china and southeast asia was advanced by south asian ships, and the chinese ships were not yet joined at that time so activity. And at least until that time, it looks there were no any remarkable buddhist movement in the southeast asian countries by where he stopped. In contrast, the southeast asian world which be seen by Iching had already experienced a lot of changes. He was impressed by the high quality buddhist culture of those area, and insisted to accept it to china. Further, he analyzed the sects of buddhism which were prevalent around the southeast asia in his contemporary time, and tried to make a good relationship with each native monks for learning from them. It looks the center of those exchanges may be Śrīvijaya of Indonesia. He also mentioned the situation of the late 7th century's Funan(扶南) in Cambodia. At that time, the buddhist Saṇgha was oppressed by newly rising Khmer(眞臘). On the other hand, he described the points of sameness and difference in detail between Indian and southeast asian buddhist culture in the field of ritual as like the practical use of garments, buddha images, and daily recited scriptures. There must be a lot of another aspects which this essay couldn't gather up or catch from these documents. Nevertheless, I hope this essay can help the researchers of this field and will wait for any advices and comments from them.

There has been no general agreement about optimal time for nerve surgery in the closed brachial plexus injury(BPI). From our early experiences, we knew by chance that spontaneous recovery in BPI patients may begin even later than 8 months after injury. Authors' strategy, which was based on our early experiences, for the treatment of closed fresh injury was 'wait and see' unlit 8 months after injury. From 1985 to 1994, we observed 103 patients with BPI. All of them did not have any operation until 8 months after injury. There were 95 men and 8 women with a mean age of 29 years. Motorcycle injury(31%) and vehicle accident(28%) were main causes of injury. Whole plexus types were observed in 56 patients(54%), upper plexus types in 29(28%), lower plexus types in 3(3%), and infraclavicular types in 15(15%). Electromyography was performed in all patients. This was repeated every three months to detect the recovery. Results were evaluated by authors' criteria, in which AMA system of brachial plexus impairment was modified. Duration of follow up was average 25 months. 47 patients(46%) showed spontaneous improvement, which was initially detected at average 7.8 months(range,3 months-16 months) after trauma by electromyography. The average score of these 47 patients improved from 14.8 points to 39.8 points.31 patients(30%) had nerve surgery such as nerve graft, neurotization or neurolysis. Average duration from injury to nerve surgery, was 10 months. Among 31 patients who had nerve surgery, 16 patients improved from preoperative 21.5 points to postoperative 36.3 points in average. Because spontaneous recovery began in average 7.8 months after injury, we think that it would be better to 'wait and see' for at least one year in patients with closed BPI expecting spontaneous recovery.

One of the most important requirements for the Ethernet-based automobile is the reliability. In order to achieve this goal, we propose using the High-availability Seamless Redundancy (HSR) protocol (IEC 62439-3 clause 5) in these networks. The HSR protocol provides duplicated frame copies for each sent frame, which means that the destination node will receive at least one copy in case the second copy is lost due to a failure. In other words, there will be no network stoppage even if failure occurs. Moreover, the destination node will receive at least one frame copy with zero-recovery time (seamless) and it will not need to wait to receive the other copy if the first one is lost, which occurs it in the Ethernet standard, as a result of reconfiguration of the network paths. However, the main drawback of the HSR protocol is the unnecessary redundant traffic that is caused by the duplicated frames. Several solutions, including QR, VRing, RURT, and DVP, have already been proposed to improve the traffic performance of the HSR protocol. In this paper, we propose three automobile network topologies. each of which has pros and cons depending on the automobile requirements. Then we applied the HSR protocol with and without the QR and VRing approaches to each scenario. The comparison among these topologies depend on the traffic performance result for each of them. The QR and VRing approaches give a better traffic reduction percentage, ranging from 48% to 75% compared to the standard HSR protocol. Therefore they could limit the redundant traffic in automobile networks when the HSR protocol is used instead of the Ethernet network, which does not provide any seamless recovery if a failure occurs.

Objectives : The aim of this study was to evaluate the effectiveness and safety of acupuncture for chronic fatigue syndrome and idiopathic chronic fatigue. Methods : A randomized, controlled pilot trial was conducted. Twenty-four participants were randomized into one of the two groups: an acupuncture group(n=12) and wait-list group(n=12). The treatment group received 12 sessions of acupuncture over 4 weeks. Eight points($GV_{20}$; bilateral GB20, $BL_{11}$, $BL_{13}$, $BL_{15}$, $BL_{18}$, $BL_{20}$, and $BL_{23}$) were selected for needling. The control group did not receive acupuncture treatment during study period and follow-up were done in the $5^{th}$ and $9^{th}$ weeks after randomization in both groups. The primary outcome was fatigue severity scale(FSS) and the secondary outcomes included a short form of stress response inventory(SRI-short form), beck depression inventory(BDI), and insomnia severity index(ISI). Safety was assessed at every visit. Results : There were statistically significant differences in the between group values of FSS at $5^{th}$ weeks after randomization(p=0.0002), SRI-short form, BDI, and ISI at $5^{th}$, $9^{th}$ weeks after randomization(p<0.01). There were no adverse events. Conclusions : The results suggest that acupuncture is associated with benefits on the short-term outcomes in chronic fatigue syndrome and idiopathic chronic fatigue.

Purpose: The purpose was to assess the usefulness of midazolam in patients undergoing minor oral surgery under conscious sedation. Materials and methods: Bispectral index was examined in 20 patients receiving oral minor surgery with conscious sedation supplemented with local anesthesia. All patients included were ASA I and had no contraindications to the study medications. The patients were escorted to the day surgery operation room where, before the commencement of the sedation and surgical procedures, routine monitoring was applied, including the noninvasive monitoring of arterial blood pressure, arterial oxygen saturation, and 3-lead electrocardiogram (Electrocardiogram). Bispectral index electrodes were applied on the frontotemporal region after cleansing the skin with alcohol. Bispectral index was calculated with the Electrocardiogram monitor (A-2000; Aspect Co.). Midazolam was then titrated (initially 3mg wait 2min and 2mg). Vital sign and Bispectral index checked every 5 minute until the end of the procedure. The results were then compared. Results: The Bispectral index index values throughout the sedation study period alter many level. The index was dropped at 5 minutes after administration, but raised at injection and odontomy procedure. During the operation, mean Bispectral index index was higher than conscious sedation index range($60{\sim}80$). The amnesic effect was shown 17 cases out of 20 cases(85%). Conclusion: Conscious sedation technique using midazolma is a safe and effective method of controlling behavior in oral and maxillofacial surgery.

Background: Intraosseous anesthesia is the process by which an anesthetic solution, after penetration of the cortical bone, is directly injected into the spongiosa of the alveolar bone supporting the tooth. This study aimed to compare the effectiveness of the traditional inferior alveolar nerve block (IANB) and computerized intraosseous anesthesia in the surgical extraction of impacted lower third molars, compare their side effects systemically by monitoring heart rate, and assess patients' a posteriori preference of one technique over the other. Methods: Thirty-nine patients with bilaterally impacted third molars participated in this study. Each patient in the sample was both a case and control, where the conventional technique was randomly assigned to one side (group 1) and the alternative method to the contralateral side (group 2). Results: The traditional technique was faster in execution than anesthesia delivered via electronic syringe, which took 3 min to be administered. However, it was necessary to wait for an average of 6 ± 4 min from the execution to achieve the onset of IANB, while the latency of intraosseous anesthesia was zero. Vincent's sign and lingual nerve anesthesia occurred in 100% of cases in group 1. In group 2, Vincent's sign was recorded in 13% of cases and lingual anesthesia in four cases. The average duration of the perceived anesthetic effect was 192 ± 68 min in group 1 and 127 ± 75 min in group 2 (P < 0.001). The difference between the heart rate of group 1 and group 2 was statistically significant. During infiltration in group 1, heartbeat frequency increased by 5 ± 13 beats per minute, while in group 2, it increased by 22 ± 10 beats per minute (P < 0.001). No postoperative complications were reported for either technique. Patients showed a preference of 67% for the alternative technique and 20% for the traditional, and 13% of patients were indifferent. Conclusion: The results identified intraosseous anesthesia as a valid alternative to conventional anesthesia in impacted lower third molar extraction.

Due to the rapid increase of vehicles on the street, Korean society is facing worsening traffic congestions and air pollutions. Also, the oil price pickup has led to increasing need for the use of public transportation. In particular, transfering among public transportation may be a main factor for riders who are commuting for a long distance journey. In order to ensure such connectivity, transfer stations have been actively built in Korea. However, it would be necessary to shift those vehicles, from cars to public transportations by enhancing the users' satisfaction with public transportation through strategies for minimizing the users' waiting cost by building an efficient connective system between transportation modes as well as the preparation of aforementioned transfer stations. Therefore, this study aimed to develop an algorithm for minimizing transferring passengers' waiting costs based on service intervals of linked buses within the transfer facilities. In order to adjust the service interval, we calculated the total costs, involving the wait cost of transfer passengers and bus operation costs, and produced an allocation interval, that would minimize the costs. We selected a KTX departing from Seoul station, and a No. 6014 bus route in Gwangmyeong city where it starts from the Gwangmyeong station in order to for verifying the model. Then, the transfer passengers' total waitting cost was reduced equivalent to the maximum of 212 minutes, and it revealed that the model performed very effectively.

Objectives : The purpose of this study is to report the effect of Korean medical treatments on idiopathic bilateral strabismus. Methods : We treated a 43-year-old male idiopathic bilateral strabismus patient who was told to wait without a prescription as there was no problem in intraocular pressure test, fundus test, brain computed tomography, brain magnetic resonance imaging and angiography test, and cerebrospinal fluid test. The patient was admitted to Cheonan Korean medical hospital for 3 months to get Korean medical treatments including acupuncture, electroacupuncture, vapor treatment, pharmacopuncture therapy. The degree of improvement in idiopathic bilateral strabismus was determined by the objective measures of internal and external rotation disorders, and the patient's subjective opinions on eye pain and double vision discomfort. Results : The results of this patient showed distinct improvements on objective measures of internal and external rotation disorders in both eyes. Distance from the outer corner of the right eye when abducted decreased from 7mm to 0mm, and left eye decreased from 7mm to 0mm. Distance from the inner corner of the right eye when adducted decreased from 5mm to 0mm, and left eye decreased from 4mm to 0mm. In addition, eye pain decreased from 10 to 0 and diplopia decreased from 10 to 2 according to the patient's subjective opinions. Conclusions : This study shows the possibility that such medical treatment in Koreans can improve the rare idiopathic bilateral perspective among strabismus patients.

China's utility model as a supplement to the invention patent, has short application duration, fast authorized speed, and has the same exclusive rights with patents, so companies can quickly dominate the market. But the utility model does not need to carry out substantive examination, so has lower stability, high frequency of invalid to accepted, so compare with the invention patent, difficult to be protected. In order to actively encourage the small and medium-sized enterprises to promote their inventions, and protect domestic patents, China established a protection policy of patent evaluation report for the utility model rights, especially the patent evaluation report can be used as evidence in a patent infringement trial, to provide judicial remedies for utility model patentee and the party of patent disputes. Many experts believe that the establishment of patent evaluation report system can improve the stability of the utility model patent right, and when the defendant request for invalidation of the patent right in the defense period, if there is no novelty, creativity lost or no other reason has not led to the stability of patent right given in a patent evaluation report of the utility model patents, the court may not suspend the trial, without having to wait for the Patent Reexamination Board makes the patent invalid declaration decisions, can improve the efficiency of the judicial process, accelerate the patentee's time. However, in practical patent infringement, the patent evaluation report system and invalidation system are in conflict. In this paper, through the analysis of the current China utility model system and compared with the South Korean utility model system, review the role and character of the patent evaluation report system, and through the actual cases of the utility model patent infringement litigation, analysis possible variates from the decision of patent evaluation report, to find out the reason of the patent evaluation report system being in conflict with the invalidation system, and research on the effectiveness for protecting Utility Model with China's Patent Evaluation Report.
