현재의 지적재산 소송의 관할은 절차의 중복으로 인하여 문제가 있다고 지적되어 있어 그 개선방안으로 관할 집중이 논의되고 있다. 지적재산 소송의 사건 현황을 보면 특허법원의 경우 특허, 실용신안 사건이 폭발적으로 증가하고 있다. 지적재산 소송의 소송대리권에 관하여는 변리사도 침해소송에서 일정한 조건하에 변호사와 공동으로 소송대리를 할 수 있도록 하는 방안이 논의되고 있다. 침해소송에서 특허 무효의 항변이 허용되는지에 관하여는 허용되지 아니한다는 종전의 대법원판결의 입장에 변화의 움직임이 감지되고 있고 실무계에서는 이를 허용하는 입법을 하자는 주장도 제기되고 있다. 특허권 등 침해로 인한 손해의 배상에 관하여 입증의 곤란함을 해소하기 위하여 특별규정을 두고 있으나 그 해석에 있어서 견해가 나뉘는 경우가 많아 실무례가 확립되어 있지 못하다. 인터넷의 발달로 인하여 지적재산 소송에도 많은 변화가 생겼는데, 영업방법 특허에 있어서의 진보성 판단기준, 새로운 형태의 표지의 사용에 대한 규제, 저작물의 유통방식의 변화에 따른 저작권법 적용의 한계 등이 문제되고 있다. Under the consideration that present jurisdiction system of intellectual property litigation causes diseconomy in judicial procedure, the jurisdictional centralization is intensively being discussed. The recent statistics of patent court shows explosive increase of patent and utility model cases. Giving patent agent the power of representation in litigation under the condition that they co-represent the client with the attorney at the law is being considered too. The Korean supreme court is moving toward the direction to allow the alleged infringer invalidation defense in infringement suit and some practitioners urge that such allowance should be legislated distinctly. Although Patent law has some provisions to relieve the difficulty to prove damages, the interpretations of law are not always compatible in the practice. The development in internet circumstances also brought various changes in IP litigation; the standard of determining nonobviousness in Business Method patent, New regulation for newly created type of trade marks and The limitation of Copyright law regime on new way of copyright matter distribution are those.

Clinical trials are more common worldwide, but there are some concerns on the protection of the public and disclosure of all information about investigational products including pharmaceuticals, biologic agents and even medical devices. In order to disclose all kinds of information about clinical trials, clinical trial registration was developed according to the decision by United States Food and Drug Administration (US FDA) and World Health Organization (WHO) separately. From July 1st in 2005, phase II to IV trials which are 'clinically directive' should be registered in the registries that are 1) easily accessible to the public, 2) free of charge, 3) open to all registrants and not‐for‐profits, 4) electronically searchable and 5) capable of ensuring validity of the registration data. This kind of registries are strongly supported by International Committee of Medical Journal Editors (ICMJE). The committee announced that they will consider a trial for publication only if it has been registered before the enrollment of the first patient. So, many multinational pharmaceutical companies have already implemented the registration and even investigators are requested to register the investigator‐sponsored trials in the clinical trials registry such as ClinicalTrials.gov. In this article, I will explain history, requirement and actual method of registration in clinical trials registry for better understanding and implementation of clinical trials in Korea.

Distributed storage systems utilize data replication to restore original data from data loss. However, this replication can diminish storage efficiency due to the production of excessive data duplicates. As such, prior research has explored methods of data storage in distributed systems using erasure codes. The Cauchy Reed-Solomon code (CRS), as one of erasure codes that exploits matrix multiplication, and techniques such as GPU-accelerated CRS (GCRS) have been proposed for its efficient processing. However, the implementation of these techniques to enhance processing efficiency paradoxically leads to unnecessary computations in the overall processing, thereby undermining performance. In this study, methods are introduced to address these issues by employing the complement of 2 and ternary operators to minimize unnecessary computations. Additionally, the study proposes the arrangement of CRS's generator matrix, taking into account the structure of the GPU. The proposed techniques are compared with the existing GPU-enabled method, GCRS, and experimental results indicate an enhancement in performance by up to approximately 30%, regardless of alterations in the data. 분산 저장소는 데이터 복제를 통해 데이터 손실에서 원본 데이터를 복구한다. 그러나, 복제는 과도한 데이터 복제본으로 인한 저장소 효율성을 감소시킨다. 따라서, 기존 연구들은 erasure code를 활용한 분산 저장소의 데이터 저장 방법을 연구하였다. Cauchy Reed-Solomon code (CRS)는 erasure code 중 하나로 행렬곱을 활용하며, 이를 효율적으로 처리하기 위해 GPU를 활용한 GCRS 등의 기법들이 제안되었다. 그러나, 이러한 기법들은 처리 과정의 효율성을 위해 적용한 것이 오히려 전체 처리 과정에서 불필요한 연산을 발생시켜 처리 성능을 저하시키는 문제가 있다. 따라서, 본 연구에서는 위와 같은 문제점을 해결하기 위해 2의 보수, 3항 연산자를 활용하여 불필요한 연산을 감소시키는 기법을 소개한다. 또한 GPU의 구조를 고려한 CRS의 생성 행렬 배치를 제안한다. 이러한 제안 기법에 대하여 기존 GPU 활용 기법인 GCRS와 비교하며, 실험 결과를 통해 데이터의 변화와 무관하게 성능을 최대 약 30% 향상시켰다.

Popliteal artery entrapment syndrome (PAES) is rare, but increasingly reported in the literature as a cause of lower limb arterial impairment. Management of a patient with PAES depends on the clinical pictures. Currently, myotomy of the medial head of gastrocnemius muscle with interposition grafting or bypass of diseased popliteal artery has been widely used in cases with a demaged or occluded artery. But, other less extensive therapeutic approaches were also performed instead of it. We present a case of type II popliteal entrapment syndrome in an 36-year-old male. Presenting symptom was exercise- induced pain in his right calf since one month ago. Arteriography showed occlusion in short segment of right popliteal artery and intact distal run-off arteries. After ovemight urokinase thrombolysis, residual focal stenosis and medial deviation of popliteal artery were observed. CT scan showed abnormal structure between right popliteal artery and popliteal vein, so, diagnosis was established. After myotomy of the medial head of gastrocnernius muscle, the symptom resolved completely. Post-operative duplex scan showed normal blood flow, even in active plantar flexion of the foot. In our case, early diagnosis and combined approach of endovascular thrombolytic therapy followed by surgical release of popliteal artery enabled to avoid direct vascular surgery such as bypass or interposition grafting with resolution of ischemic symptoms. This thrombolytic therapy does not obviate surgery but may permit a less extensive procedure to be performed in PAES.

평화에 대한 인식과 평화를 이루는 방법에 대한 저해요인을 지적하는 것도 물론 중요하지만 더욱 중요한 것은 평화의 유지일 것이다. 근대국가에서의 평화유지는 일국의 힘으로써만은 곤란하다. 그것은 집단적인 힘으로 상호간의 이해를 초월해서 협력할 때 가능한 것이다. 국제정의와 국제협력에는 결국 자국, 타국의 공동운명체 관념이 앞선다. 우리가 우리의 평화를 유지하고자 할 때는 국제적 협력을 바라고 또 협력을 하기 전에 국민각자의 총의를 집중해서 안이하고 형식적인 평화관념을 버리고, 활동하는 국민을 위한 평화유지가 중요하다고 할 수밖에 없다. Hydrothermally grown ZnO single crystal junction varistor was prepared, and their voltage-current relation was studied. The single crystal bonded varistor showed various voltage-current relationship and different breakdown voltage of 0.7-3 volt. Various varistor behaviour was considered from the various electrical conductivity of hydrothermally grown ZnO single crystal.
