Introduction: The aim of this study protocol is to share and disclose the methodology used to develop an evidence-based clinical practice guideline (CPG) of therapeutic interventions used in Korean medicine for patients with stroke. Methods: The CPG development process will consist of two phases. In phase I, a development committee will be established, and they will decide the key questions to be answered. A systematic review and meta-analysis will be performed to answer these key questions by searching relevant randomized controlled trials and systematic reviews. Draft recommendations will be developed according to the evidence level and recommendation grades primarily determined using the GRADE methodology. Panels comprised of external experts will be formed, and surveys and a face-to-face meeting will be conducted to reach a consensus on the recommendations. A preliminary guideline will be created after final review by the development committee. In phase II, we will conduct clinical trials and economic analysis to supplement the lack of evidence found in the phase I. Conclusion: The CPG is expected to help doctors practicing Korean medicine in clinics or hospitals with making decisions based on the most reliable evidence, ultimately leading to the provision of optimal care for patients with stroke.

현대 의학은 과학과 더불어 놀라운 만큼 발전을 거듭하고 있기에 각종 암 환자의 조기 발견으로 인하여 인간의 생명 연장에 큰 공헌을 하고 있다. 조기 발견의 일환으로 시행되는 핵의학 검사 중에서 Bone scan을 통한 암 환자의 전이 여부와 전이되는 시기, 정도를 연구함으로서 암 발견의 초기와 말기의 차이뿐만 아니라 그 시기를 추정한 데이터로 적극적 치료를 수행할 수 있기를 기대하고자 한다. 더불어 암 판정을 받은 환자는 그 시기를 더 지연시킬 수 있는 필요적 방어를 수행할 수 있도록 최대한 지도가 가능하리라 판단이 된다. 암 판정의 초기에는 부단한 노력과 투자로 검사와 치료를 병행하다가 일정시간이 경과하고 난 후에는 다소 소홀해지는 경우가 빈번하게 나타남을 알 수 있었으며, 그로 인해 암세포의 전이가 활발하게 진행되어짐을 확정할 수 있었다. 이는 치료 목적을 가지고 대하는 각 의료기관 및 의료기관 종사자에게 있어 간과 할 수 있는 부분이 아니므로 보다 적극적 대처를 요하는 사안이다.

New Jersey Institute of Technology (NJIT), in collaboration with the University of Hawaii (UH), is upgrading Big Bear Solar Observatory (BBSO) by replacing its principal, 65 cm aperture telescope with a modern, off-axis 1.6 m clear aperture instrument from a 1.7 m blank. The new telescope offers a significant incremental improvement in ground-based infrared and high angular resolution capabilities, and enhances our continuing program to understand photospheric magneto-convection and chromospheric dynamics. These are the drivers for what is broadly called space weather - an important problem, which impacts human technologies and life on earth. This New Solar Telescope (NST) will use the existing BBSO pedestal, pier and observatory building, which will be modified to accept the larger open telescope structure. It will be operated together with our 10 inch (for larger field-of-view vector magnetograms, Ca II K and Ha observations) and Singer-Link (full disk H$\alpha$, Ca II K and white light) synoptic telescopes. The NST optical and software control design will be similar to the existing SOLARC (UH) and the planned Advanced Technology Solar Telescope (ATST) facility led by the National Solar Observatory (NSO) - all three are off-axis designs. The NST will be available to guest observers and will continue BBSO's open data policy. The polishing of the primary will be done in partnership with the University of Arizona Mirror Lab, where their proof-of-concept for figuring 8 m pieces of 20 m nighttime telescopes will be the NST's primary mirror. We plan for the NST's first light in late 2005. This new telescope will be the largest aperture solar telescope, and the largest aperture off-axis telescope, located in one of the best observing sites. It will enable new, cutting edge science. The scientific results will be extremely important to space weather and global climate change research.

This paper deals with the recognition algorithm of walking will based on torque estimation. Recently, concern about walking assistant aids is increasing according to the increase in population of elder and handicapped person. However, most of walking aids don't have any actuators for its movement. So, general walking aids have weakness for its movement to upward/download direction of slope. To overcome the weakness of the general walking aids, many researches for active type walking aids are being progressed. Unfortunately it is difficult to control aids during its movement, because it is not easy to recognize user's walking will. Many kinds of methods are proposed to recognize of user's walking will. In this paper, we propose walking will recognition algorithm by using torque estimation from wheels. First, we measure wheel velocity and voltage at the walking aids. From these data, external forces are extracted. And then walking will that is included by walking velocity and direction is estimated. Here, all the processes are verified by simulation and experiment in the real world.

The discoveries of high temperature superconductors received great attention due to their high critical temperatures. These materials also exhibit extremely high critical magnetic fields and high critical current density at low temperature, high magnetic field. Thus, they are the most promising materials for superconducting magnets above 20 T. In this talk, progress in the development of HTS materials and insert coils at the National High Magnetic Field Laboratory will be reviewed. In 1999, a Bi-2212 stack of double pancakes generated 3 T in a 19 T background field. These results will be reviewed in terms of implications for future systems. Individual double pancakes of Bi-2223 have also been tested and their performance will also be discused. The present goal of a 57 system will be presented and the key technical requirements for larger, higher field systems will be addressed. It will be shown that in addition to increased critical current density, improved mechanical performance (stain resistanced) is necessary for high field systems. Furthemore, improvements in the conductor n-value will improve prospects for operational systems.

The Square Kilometre Array (SKA) will be the world's largest and most sensitive radio telescope. It will address a wide range of fundamental questions in physics, astrophysics, cosmology and astrobiology. Australia, one of the two countries selected to host the SKA, has spent several years preparing by opening up the Murchison Radio-astronomy Observatory (MRO) as a uniquely radio quiet site in Western Australia, and by constructing the world's most powerful radio survey telescope, the Australian SKA Pathfinder (ASKAP). The SKA will be built in two phases. Phase I will include ASKAP, which will use novel phased-array feeds and grow to become "SKA-survey". Phase I will also include a dish array ("SKA-mid") in South Africa and a low-frequency array ("SKA-low") in Australia, and is slated for operation from about 2020. Phase II of the SKA will consist of further expansion of SKA-low and SKA-mid and is due for completion in the middle of the next decade.

The response to climate change of international air transport industry might be initiated by ICAO's CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation) which will impact on international airlines' flight operation behavior in the future. Though the airlines' efforts to reduce fuel consumption has been a major issue in economics of aviation industry, the improvement of fuel efficiency in flight operation will have additional impact on their profitability by introducing carbon emission cost. The fuel consumption in flight operation will be somewhat influenced by pilots' technical action for maneuvering aircraft during flight operation. This study will investigate pilots' behavior on decision for tactical aircraft control for mission flight. The data will be collected by the survey through sample pilots asking about their intention and perception on fuel savings during flight operations. The data will be analyzed by AHP process and the study will find out the elements and factors influencing pilots' behavior on technical decision of flight and their weights on fuel saving effects.
