Two years ago, an emergency arbitrator procedure in accordance with the international arbitration rule has been finally adopted in Korea?a decade after its introduction. Arbitral institutions provide interim measures in the course of tribunal proceedings to avoid litigation in open court that is often expensive and time-consuming. An emergency arbitrator procedure offers an urgent relief prior to the constitution of an arbitral tribunal, thus enhancing the speed and effectiveness of the arbitration procedure even further. Although most of the arbitral institutions interpret that the emergency arbitration rulings are binding on the parties, enforcing the emergency arbitration provisions have some difficulties in practice, and it is not clear whether or not arbitral interim measures will be enforceable under the newly adopted provisions in Korea. In this study, experiences in other countries are explored in seeking for the possible problems and solutions of enforcing the emergency arbitration rulings. For example, Singapore and Hong Kong insert terms such as "finality," "enforceable in the same manner as an order or direction of the Court," "same effect as an arbitral tribunal or interim measures" in their emergency arbitrator legislation to enhance enforcement. Moreover, "urgency inherent" are considered.

Background: Surgery has been known as an inefficient approach to reduce back pain in patients with lumbar spinal stenosis; therefore, non-surgical treatments are necessary. However, there has been little research to analyze the effect of non-surgical treatments on lumbar spinal stenosis pain. Objective: To identify the effectiveness of 2 physiotherapeutic treatment approaches to relieve pain due to lumbar spinal stenosis. Design: Randomized controlled trial Methods: The participants were 36 lumbar spinal stenosis patients who were randomized in the joint mobilization group (JMG) and transcutaneous electrical nerve stimulation group (TENSG). Joint mobilization (JM) was conducted at the posteroanterior joint in the spinous process of the lumbar spine with stenosis. Transcutaneous electrical nerve stimulation (TENS) was applied on the lumbar spine with stenosis at a high frequency and intensity. Results: Visual analog scale (VAS) pain score significantly decreased in both groups, and the VAS value decreased more after JMG than that after TENSG. The pain thresholds of both groups also significantly increased, and that of JMG increased more compared to TENSG. In both the groups, significant improvements in VAS and pain thresholds were found, and JMG showed better results than TENSG. Conclusions: JM and TENS showed significant relief in both pain threshold and painpain, and JM showed more advanced relief compared to TENS.

The sciatic nerve is the largest nerve among the peripheral nerves, and the damage to the sciatic nerve is caused by mechanical and physical pressure. This is an important disease that consumes a lot of time and money in the treatment process. Among them, research on relieving nerve pain caused by damage to the peripheral sciatic nerve has been made efforts to prevent and treat this disease through various methods such as drugs, natural products, electrical stimulation, exercise therapy, and massage. Existing treatments are not very effective in neurological pain, and countermeasures are needed. Forsythia Fructus, used in this study, has been used as a therapeutic agent for infectious diseases and a pain reliever for cancer from the past, and in past studies, it has been known to properly control the inflammatory response. In this study, rengyolone, a physiologically active substance of Forsythiae Fructus, was administered to rats that caused chronic left nerve pain to verify the pain relief effect. As a result of the experiment, it was found that mechanical pain and cold stimulation pain were significantly reduced in the rengyolone-treated group compared to the non-administered group. In addition, it was found that nerve growth factor (NGF) mRNA expression was significantly reduced and Cyclin-dependent kinase 2 (Cdc2) expression was increased in the rengyolone administration group. This increase in NGF expression is thought to be related to rengyolone's anti-inflammatory regulatory mechanism. It is expected that the reduced NGF was directly involved in pain relief.

Rising urban flood patterns are a universal phenomenon and a significant challenge for city government and urban planners worldwide. Urban flood problems range from relatively localized incidents to substantial incidents, which lead to cities being flooded for a few hours to several days. Therefore, the effect may be widespread, such as the temporary displacement of individuals, disruption to civic facilities, water quality degradation and the possibility of epidemics. The problems raised by urban flooding are highly challengeable and compound by ongoing climate change, with adverse implications for changes in rainfall and gaps in intra-urban rainfall distribution. Unplanned construction and invasions of large houses along rivers and watercourses have interfered in natural rivers and watercourses. As a result, the runoff has risen in proportion to the urbanization of the urban floods. The location of the relief camp and the priority for evacuation were determined, and the safest route to avoid floods were established. This method can be used for emergency planning in future flood incidents, and it will help plan disaster preparedness for Panchayat. This study will promote the flood plain's potential use for disaster management and land use planning virtually.

This review evaluated the efficacy of electroacupuncture (EA) for chronic fatigue syndrome. Randomized controlled trials (RCTs) using EA as an intervention for patients with chronic fatigue syndrome were identified in 6 databases (PUBMED, EMBASE, CNKI, J-STAGE, KMBASE, OASIS). Fatigue indicators were used as the primary outcome measures. The quality-of-life index, efficiency rate, and level of pain were used as secondary outcome measures. There were 408 patients from seven RCTs included in this study. Meta-analysis showed that EA was significantly associated with fatigue relief compared with the control group (n = 141 SMD = -1.55, 95% CI; -2.58 - -0.52, p = 0.003, I² = 92%). In addition, EA had a statistically significant improvement in quality of life compared with the control group (n = 176, SMD = -2.29, 95% CI; -3.68 - -0.90, p = 0.001, I² = 96%). One study reported ten cases of bleeding, however, no serious adverse events were reported in any of the included studies. This review determined that EA may have a greater clinical effect than the control group for fatigue relief and improved quality of life. However, there were several risks of bias identified. Not all of the RCTs accurately reported the research method, all studies were conducted in 1 country (China), and the number of studies included were small.

Purpose: The purpose of this study is to derive solutions and prevent similar cases from occurring by analyzing the causes of cracks found in temperature cycling tests of rocket motor. Methods: By combining the results of the current state confirmation test, non-destructive test, domestic and foreign rocket motor comparison test, cutting test, and adhesion test according to the number of times to apply mold release agent, a Cause and Effect Diagram analysis was performed to derive the cause of cracks. Results: Through this study, 26 factors that could cause cracking in rocket motors during temperature cycling tests were identified. Through various additional test results, a total of five causes were identified, including chemical and structural design of the joint between the propellant and stress relief insert, omission of procedure in the manufacturing procedures, natural aging due to temperature, and load accumulation due to temperature changes. The fundamental cause was confirmed to be insufficient consideration of the release properties of the propellant and stress relief insert. Conclusion: During the design process, it was confirmed that this could be solved by structurally or chemically designing the insert so that it does not combine with the propellant, or by applying a mold release agent during the manufacturing process.

In this study, the sliding wear in spur gears, using Archard's wear model, is analyzed. Formulas of tooth sliding wear depth along the line of action are derived. The tooth profile is modified Id make a smooth transmission of the normal loads and the cylinder profile for reducing the pressure spike is suggested. The sliding wear rate is calculated with these profiling results. We expect these modification methods to contribute to the reduction of sliding wear not only in the root, but the tip of tooth and tooth edge.
