  • 무용제 타입의 hot melt계 중 styrene-isoprene-styrene(SIS) 블럭공중합체에 대한 tackifier resin의 상용성과 점탄성, 그에 영향을 미치는 점착물성에 관해 조사하였다. SIS블럭공중합체의 이소프렌상에서는 $C^5$ petroleum resin이 상용성이 우수하며, coumarone-indene resin은 전혀 상용성을 보이지 않았다. 그에 따른 점착력, 초기점착력, 견지력 등의 점착물성은 $C^5$ petroleum resin>rosin ester resin>coumarone-indene resin순으로 나타났으며, 고무상에서 상용성이 우수한 tackifier resin이 효과적임을 알았다. 한편, 이때의 저장탄성률(G')에서, plateau modulus값이 $1{\times}10^6-3{\times}10^6dyn/cm^2$일때 점착력이 가장 우수하였다.

  • Purpose: The aim of the study was to investigate items of commonly used questionnaires that measure functioning status of persons with stroke and map to the International Classification of Functioning, Disability and Health (ICF). Methods: Eighty-six patients with stroke were recruited from 12 medical institutes for the study. Each item of the Modified Bathel Index (MBI), Stroke Impact Scale (SIS), Mini Mental Status Evaluation (MMSE) and SF-36 were examined and compared its concept with the ICF. Concept linking was performed by 10 health professionals independently. A field test was performed to assess its correlation between those of scales and their linked ICF category sets. Results: It was found that 11 items in MBI was linked to 14 ICF categories, whereas 27 items of MMSE had 10 categories of ICF linked. 60 items of SIS were to be linked with 35 ICF categories. Agreement between professionals in linking was found to be high: 97.5% for MBI items, 78.0%, 78.0%, and 74.8% for MMSE, SIS, and SF-36 respectively. Strong relationship was observed between measurement scales and linked ICF code sets (r=-0.76 for SIS, r=-0.78 for MBI, r=-0.47 for MMSE) whereas there was no relationship was found between SF-36 and its ICF code set (r=-0.06) from the field test. Conclusion: It was found that items of SIS, MMSE and MBI may be linked to ICF categories. Those of linking concept between clinical tools and the ICF could be helpful for clinical data standardization.

  • In recent years, the companies of electric power equipment for MV, HV class trend to develop that the eco-friendly insulated(solid, eco-gas, air etc.) switchgear replace with existent SF6 gas insulated switchgear by environmental problems such as global warming and soon. This paper introduces the Solid Insulated Switchgear(SIS) which is the epoxy of eco-friendly insulation material. The characteristic of SIS to introduce in this paper is as following. 1) Eco-friendly. (SF6 gas free) 2) The structure of flexible system. (Expansion) 3) The optimum design. (The Analysis of electrical & mechanical) 4) An Interface treatment between epoxy and insert. (Molding technology) This paper described about some technology for development of SIS.

  • 본 논문에서는 화상 신호처리 및 컴퓨터 그래픽스 요소기술을 이용하여, 컴퓨터 상에서 인공고관절의 시술절차를 적용해 보기 위한 Simulated Implantation System (이하 SIS)을 소개한다 SIS는 일련의 자동화된 절차에 따라, 골반(pelvis)과의 접촉이 이루어지는 대퇴골의 상단부위인 고관절(femoral head)을 대체하는 과정을 3차원적으로 가상 수행할 수 있으며, 환자의 고관절과 인공고관절간의 정합정도를 수치적으로 해석할 수 있는 기능을 궁극적 목표로 하게 된다. 이를 위해 필수적으로 필요한 CT-Image를 이용한 고관절 영상의 3차원 재구성, 그리고 projection image글 이용한 인공고관절의 3차원 표현기법에 대해 논의하고, 각각에 대응되는 결과물들을 분석해봄으로써 현재 의공학 분야에서 절실히 요구되고 있는, 영상신호처리와 컴퓨터그래픽스를 이용한 SIS의 prototype에 대한 모습을 제시해 보고자 한다

  • Because of their high sensitivity and moderate bandwidth, superconducting receivers with SIS (Superconductor Insulator Superconductor) tunnel junction mixer are now widely used for millimeter wave radio astronomy. In this paper we have introduced how to determine the parameters of SIS tunnel junction which have to be optimized to achieve a good mixer performance. From these results of optimized junction parameters determined by this methods, SIS junctions which consist of a series array of four Nb/Al-AlOx/Nb junctions with each area 3.4${\mu}m^{2}$ have been fabricated by SNEP (Selective Niobium Etching Process) and RIE (Reactive Ion Eching). Also we have tested their DC current-voltage characteristics. These SIS junctions will be used as a mixer for 100GHz band cosmic waves receiver.

  • Software inspection is widely believed to be an effective method for software verification and validation (V&V). However, software inspection is labor-intensive and, since it uses little technology, software inspection is viewed upon as unsuitable for a more technology-oriented development environment. Nevertheless, software inspection is gaining in popularity. KAIST Nuclear I&C and Information Engineering Laboratory (NICIEL) has developed software management and inspection support tools, collectively named "SIS-RT. "SIS-RT is designed to partially automate the software inspection processes. SIS-RT supports the analyses of traceability between a given set of specification documents. To make SIS-RT compatible for documents written in Korean, certain techniques in natural language processing have been studied [9]. Among the techniques considered, case grammar is most suitable for analyses of the Korean language [3]. In this paper, we propose a methodology that uses a case grammar approach to analyze the traceability between documents written in Korean. A discussion regarding some examples of such an analysis will follow.
