The purpose of this study was to identify the effects of continuous muscle strengthening applied to the antagonist of the sternocleidomatoid, upper trapezius, and pectoralis major, which are the shortened muscles of forward head posture(FHP) subjects, and Evjenth-Hamberg stretching(EHS) applied to the shortened muscles on changes in pressure pain threshold(PPT). Twenty subjects were divided into the continuous antagonist strengthening(CAS) group(n=10) and the EHS group(n=10), and each group performed its respective exercise three times a week for a six week period. The results were as follows: The comparison of changes in PPT within each group before and after the treatment showed a statistically significant difference(p<.05) according to the treatment period and a statistically significant difference according to the treatment period and method(p<.05). While the comparison of the tests of between subjects effects between the groups did not show a statistically significant difference, the CAS group exhibited better effects. The above results suggest that the combined application of CAS and EHS generates better effects on changes in PPT than the single application of EHS. Given that stretching and muscle strengthening exercises even for the short research period of six weeks could change the PPT, continuous exercises and a correct postural habit for a longer period of time are likely to help prevent chronic pain and correct FHP.

Piriformis Syndrome is characterized by pain of the low back, groin, perineum, buttock, hip, posterior thigh, leg and foot. Symptoms are aggravated by sitting, prolonged combination of hip flexion, adduction, the medial rotation, or by activity. In addition, patient may complain of painful swelling of the limb and sexual dysfunction-dyspareunia in female, and impotence in male. It currently appears that three specific conditions may contribute to the piriformis syndrome: (a) myofascial pain; (b) nerve and vascular entrapment; (c) dysfunction of the sacroiliac joint. The important keys of diagnosis are history and physical examination. There is no known objective diagnostic method. We described the clinical features of four cases of piriformis syndrome and reviewed foreign literature.

In out-patient clinic, it seems to be common that most back pain arise from muscular origins rather than from skeletal origins. Most physicians have wished to diagnose lower back pain from the radiologic findings only. From clinical experiences and anatomical studies, I have gotten a different opinion from common sense about backaches. If I met a patient who had lower back pain around the posterior superior iliac crest(P.S.I.C.) area, I would had to search a trigger point in the erector spinae muscles at the level of thoraco-lumber junction rather than at the level of the painful site. It is why that sensory innervation over the posterior superior iliac crest area is the posterior primary branch of T12 spinal nerve running down through the erector spinae muscles. Pain on the iliac crest area is supposedly due to hyperirritability of the sensory nerve distributing to this area. Hyperirritability of the posterior primary branch of $T_{12}$ spinal nerve may be due to the spasm of the longissimus thoracis muscle in the erector spinae muscles at the level of the thoraco-lumbar junction. So finally, I would like to insist that spasmolytic treatment on the muscle at the level of the thoraco-lumbar junction would be better for pain relief around P.S.I.C. than treatment at the painful site only.

With the development of high-speed railway technologies, train velocities can now reach speeds up to 350 km/h, and higher in the future. In high-speed railway systems (HSRs), loss of communication can result in serious accidents, especially when the train is controlled through wireless communications. For to this reason, operators of Long Term Evolution for Railway (LTE-R) communication systems install eNodeBs (eNBs) with high density to achieve highly reliable communications. However, densely located eNBs can result in unnecessary frequent handovers (HOs) resulting in instability because, during every HO process, there is a period of time in which the communication link is disconnected. To solve this problem, in this paper, an HO scheme based on the maximum cell residence time (CRT) and adaptive time to trigger (aTTT), which are collectively called CaT, is proposed to reduce unnecessary HOs (using CRT estimations) and decrease HO failures by improving the handover command transmission point (HCTP) in LTE-R HSR communications.

Piriformis muscle syndrome is a condition that causes direct muscle pain around piriformis muscle or sciatica from irritated sciatic nerve and the diagnosis remains debatable. The main treatment is symptomatic relief from conservative therapy such as medication and piriformis stretching exercise, and various therapeutic injections including local anesthetic, corticosteroid, botulinum toxin can be considered for diagnostic and therapeutic purposes. In this case, a 54-year-old male who had sciatica and gait disturbance showed piriformis muscle hypertrophy in the pelvis MRI. From imaging studies, electrodiagnostic study and physical examination, he was diagnosed with piriformis muscle syndrome. He underwent trigger point injection and botulinum toxin injection into the piriformis muscle, and pain and gait disturbance significantly improved. This case reports a case of piriformis muscle syndrome with clinical symptom of gait disturbance, which was improved by botulinum toxin injection.

There are many wrist and hand diseases in which ultrasound can help in the diagnosis and treatment. Because many small structures are located, identifying anatomical locations and pathways is especially important. In De Quervain's syndrome, it is necessary to find tendon lesions located in the first compartment of the wrist. If injection therapy is required, administer the regimen accurately within the tendon sheath through ultrasound. In carpal tunnel syndrome, there are several methods to diagnose a disease by measuring cross-sectional area of the median nerve. Ultrasound has the advantage of administering injection therapy without damaging the nerve. Intersection syndrome can be diagnosed by observing swelling and hypoechoic appearances at the point where the tendons of the first compartment cross over the second compartment of the wrist. Ultrasound-guided injection is also safe and efficient. If there is a trigger finger lesion, the most representative findings is to observe a nodular hypoechoic thickening of the involved A1 pulley. When injection therapy is performed, it is effective to administer medication between pulley and flexor tendons as much as possible to reduce pressure on the attached structures.

Objectives : Cervical herniated intervertebral disc (HIVD) are common diseases. They can be managed with acupuncture, but the evidence for effectiveness is uncertain. This review analyzed the acupuncture studies of domestic neck pain and cervical HIVD; the purpose of this study was to provide basic data useful for future research. Methods : We investigated acupuncture treatments for neck pain and cervical HIVD by searching 5 Korean Internet databases. The keywords used were "neck pain", "HIVD-cervical spine", and "nuchal pain". A total of 53 research papers (17 case reports, 16 clinical data analyses, 11 randomized controlled trials, and 9 non-randomized controlled trials) were found and analyzed according to the publication year, type of study, treatment, use of filiform needles, and type of pharmacopuncture used acupoint. The effectiveness of acupuncture treatment was determined. Results : 1. Filiform needles have been primarily used in domestic research and were used in at least half of published pharmacopuncture studies. 2. In 51 papers using filiform needles, many studies used only local acupoints; few studies used only distant acupoints. 3. All studies using pharmacopuncture were performed using local acupoints. In particular, the studies based on A-shi point, trigger point, and radiologic lesion sites were useful for multiple purposes. Conclusion : In this study, we analyzed the acupuncture contents of the domestic neck pain and HIVD-cervical spine clinical studies. This study considers the assessment of the quality and efficacy of each study, which is likely to require research that reflects the future.

이벤트 기반 서비스 기술은 실시간으로 발생하는 이벤트를 감지하고 분석하여 이에 대한 반응으로 서비스가 연동되는 기술로, 실시간 기업 환경 구축이나 유비쿼터스 서비스 환경 구축을 위한 핵심 기반 기술이다. 실시간 기업 환경에서 요구되고 있는 기업 내 업무 프로세스에서 발생하는 다양한 정보를 실시간 모니터링, 분석하여 변화에 대한 신속한 대응을 제공하거나, 유비쿼터스 서비스 환경에서 상황에 맞게 적시에 맞춤형서비스를 제공하기 위해서는 이벤트 기반의 서비스 기술이 요구된다. 최근 이벤트 중심의 비즈니스 프로세스로 복합 이벤트 처리(CEP : Complex Event Processing) 방식이 사용된다. 복합 이벤트 처리 방식은 여러 이벤트 소스로부터 발생한 이벤트를 대상으로 이벤트들의 영향을 분석하여 대응되는 액션을 처리하는 방식으로 가장 핵심이 되는 기술은 어떻게 사용자에게 의미있는 이벤트(복합 이벤트)를 검출하는가이다. 기존의 연구에서는 복합 이벤트를 구성하는 모든 이벤트가 발생하지 않아도 부분적으로 발생하는 이벤트에 대해 계속적으로 연산을 수행하여 많은 연산과 많은 메모리를 소비하는 문제점이 있다. 이러한 문제를 해결하기 위해 본 논문에서는 대용량의 스트림 데이터에서 발생한 모든 이벤트를 처리하지 않고 응용 계층에서 등록한 복합 이벤트를 구성하는 모든 이벤트가 발생하면, 복합 이벤트를 처리하는 이벤트 검출 기법을 제안한다. 제안 하는 기법은 먼저 비트맵 인덱스를 이용하여 이벤트의 발생 유/무를 관리한다. 또한 복합 이벤트 질이의 마지막 이벤트를 트리거 이벤트로 정의하며, 이 트리거 이벤트가 발생하는 시점을 통해 이벤트의 발생을 표시한 비트맵 인덱스에 복합 이벤트를 구성하는 모든 이벤트의 발생 유/무를 검사하여 모든 이벤트가 발생하였다면, 연산을 수행할 수 있도록 제안한다. 제안하는 기법은 실험을 통해 복합 이벤트를 구성하는 이벤트의 검사를 매번 수행하지 않고 모든 이벤트가 발생하였을 때에만 연산을 수행함으로 불필요한 연산을 방지하고, 처리하는 이벤트의 수를 감소시켜 연산의 효율성을 증가 시켰다.
