The purpose of this study is to survey the present women's golf windbreaker market to develop the trendy product with supplementing design and functionality by grasping the inconvenient part through the result of the questionnaire. According to the questionnaire, 38.1% said that the armhole is the most inconvenient part by tightfitting. Therefore, a mobility of wearer was enhanced by giving shirring detail to the armhole for flexibility through inserting the elastic band with a regular interval around armhole in the design1. The swing movement was allowed to be convenient by attaching knit to the side panel. And, the sleeves were designed in the detachable form so those are allowed to be produced in two kinds such as long sleeves and short sleeves. In the design2, a zipper was inserted from the neckline to the armhole so it is designed a detachable bolero. Furthermore, it was designed to be possible to wear two different way as a jumper style and a vest style. Given wearing a vest, the sleeve part was patched knit, thereby having enhanced activity. The design1 and the design2 evaluated an objective assessment and subjective assessment. Assessment group consists of 5 subject groups and 10 expert groups to evaluate external appearance and movement adaptability. In the external appearance evaluation, the design1 obtained the better evaluation than design2. In the movement adaptability evaluation, the design1 obtained the better evaluation than the design2 for all of the items except the wrist area. In the group of professionals, the design1 obtained the better evaluation than the design2 for all of the items except the bottom area.

This research presents a prototype development and implementation of Decision Support System (DSS) for integrated river basin water management for the flood control. The DSS consists of Relational Database Management System, Hydrologic Data Monitoring System, Spatial Analysis Module, Spatial and Temporal Analysis for Rainfall Event Tool, Flood Forecasting Module, Real-Time Operation of Multi Reservoir System, and Dialog Module with Graphical User Interface and Graphic Display Systems. The developed DSS provides an automated process of alternative evaluation and selection within a flexible, fully integrated, interactive, centered relational database management system in a user-friendly computer environment. The river basin decision-maker for the flood control should expect that she or he could manage the flood events more effectively by fully grasping the hydrologic situation throughout the basin.

The acoustic emission (AE) technique is a well-known non-destructive test technique, both in research and for industrial applications. It is mainly used to monitor the onset of cracking processes in materials and components. Predicting and preventing the crack phenomenon has attracted the attention of many researchers and has continued to provide a large incentive for the use of condition monitoring techniques to detect the earliest stages of cracks. In this research, goal is in grasping features of AE signal caused by crack growth. The envelope analysis with discrete wavelet transform (DWT) is used to find the characteristic of AE signal. To estimate feature of divided into three by crack length, the time waveform and the power spectrum were generated by the raw signals and the transferred signal processed by envelope analysis with DWT.

There has been a need for predicting development efforts and costs of the system during the early stage of the software process and hundreds of metrics have been proposed for computer software, but not all provide practical support to the software engineer. Some demand measurement that is too complex, others are so esoteric that few real-world professionals have any hope of understanding them, and others violate the basic intuitive notions of what high-quality software really is. It is worthwhile that metrics should be tailored to best accommodate specific products and processes after grasping their good and no good point. This paper describes two size estimation techniques, the Karner technique and the Marchesi technique, and compares and analyzes them with proposed evaluation criteria. Both techniques are to estimate software size analyzed by use case that is mainly described during the object-oriented analysis phase. We also present an empirical comparison of them, both are applied in the Internet Medicine Prescription System. We also propose some guidance for experiments based on our analysis. We believe that it should be facilitating project management more effective by adjusting software metrics properly.

This paper proposes a performance index for the multiple shape object handling of dual arm manipulator to determine whether a robot is good or not. When the dual-arm manipulator grasps a fixed object and is posed, the dual-arm manipulator should procure a space to freely control the manipulator. As a performance evaluation parameter, each joint torque from current sensor signal is utilized. From the current information, torque and energy for each joint are estimated. In this paper an performance index for an unstructured object is defined by an energy-cost function, and stability analysis for each motion is derived by the maximum force to the object. The maximum force to the object is computed by the inertia of object and acceleration information of end-effector. The acceleration data are derived by the double derivation of each encoder signal. Manipulability measure which implies how efficiently the dual-arm manipulator can move with the grasped object, can be represented by the intersection of the two manipulability ellipsoids for the left and right arms. Effectiveness of the proposed algorithm has been verified through the practical simulations and real experiments.

Multi-arm cooperation robot system is required for more specific and dextrous jobs such as transferring very large or heavy objects, or grasping work piece while processing on it. There is little research on 3-dimensional multi-arm robot. Here we propose two performance indices presenting isotropy of end-effector's acceleration and velocity capabilities with constraints of joint torques, that is Isotropic Acceleration Radius [IAR] and Isotropic Velocity Radius [IVRI. Also the procedure to find 3-dimensional IAR, IVR is proposed, where available acceleration set concept is used. The case of 3-dimensional two 3 joint robot system was simulated and the distributions of IAR, IVR was studied.

일반적으로 응용프로그램에서 병렬성 추출에 대한 핵심 부분은 루프이고 루프내의 첨자변수들 사이에는 자료종속성이 존재한다. 특히 문장들 사이에 가변 및 불변종속거리를 갖는 종속관계는 매우 복잡하다. 따라서 이 경우 컴파일 시 병렬성 추출은 매우 어렵다. 따라서 본 논문에서는 기존에 제시되어있는 병렬성 추출 방법들 중에서 unimodular방법과 non-unimodular방법에 대하여 분석하고 이들의 장단점을 파악하여 향후 효율적인 종속성 제거방법을 제안하는데 도움이 되고자한다.

Vegetation shows unique spectrum characteristics compared with other materials. If such characteristics are used, land change pattern can be determined. Thus, vegetation has an absorption belt and a reflective belt in visible and near infrared, and reflectance is very high. Then, various methods of monitoring vegetation paying attention to the absorption wavelength region and reflective region of vegetation are proposed. However, there are various problems in grasping change of vegetation by NDVI, PVI, etc. It is very difficult especially to remove various noise ingredients in the received satellite data. Until now, it is difficult to compensate for shadow effect when NDVI is used in vegetation analysis. The results is, if the shadow is about 60% the pixel will be wrongly classified as may be vegetation or not.

포트폴리오는 장기간에 걸친 학생의 학습과 성장을 타당하게 평가할 수 있는 방법을 제공하며 자기반성을 통하여 실제적 학습을 가능하게 한다. 하지만 포트폴리오의 운영 실태에 따르면 실시에 있어 시간 소요, 장기 보관의 어려움 등으로 인하여 일회적이고 평가를 위해 형식적으로 운영되고 있는 실정이다. 본 논문에서는 학생의 학습 과정과 성장 결과를 총체적으로 파악한 후에 포트폴리오 실시에 따른 물리적 제약요인을 줄이기 위해 학습과 평가를 통합한 e-포트폴리오를 설계한다. 설계한 e-포트폴리오 모델의 효과성을 검증하기 위해 블로그를 기반으로 e-포트폴리오를 운영한 결과 학생들의 학업 성취도에 유의미한 변화가 있었으며 교사를 대상으로 한 활용 가능성도 긍정적으로 나타났다. 따라서 본 연구에서 제안한 e-포트폴리오 운영으로 학습과 평가 기능이 상호 작용적으로 통합된 보다 진전되고 의미 있는 포트폴리오 활용 교육이 기대된다.

본 연구에서는 문헌 연구, 설문 조사, 수업관찰 및 교사 면담 등을 통하여 수업평가 기준의 목적, 개발이 필요한 이유, 수업평가 기준의 역할 등을 살펴보았다. 이어서 현장 교사들이 생각하는 수업평가 기준 개발의 바람직한 주체가 누구이며, 수업평가 기준이 개발될 경우 누가 가장 많은 혜택을 받을 것으로 기대하는지를 살펴보고, 나아가 수업평가(기준) 정착을 위한 선결 요건을 고찰하였다. 요약하면, 수업 평가기준은 (1) 초보자를 위한 지침, (2) 숙련된 전문가를 위한 지침서 (3) 개선 노력을 집중할 부분을 파악하는 구조, (4) 교직이외의 다른 공동체들과의 의사소통의 수단이 될 수 있다. 또한, 수업평가는 물론 수업평가 기준 개발의 주체는 교사들이어야 하며, 일반 기준과 차별화 되는 교과별 기준, 즉 과학과 수업평가 기준 개발의 필요성을 논의하였다. 즉, 교과별 수업평가 기준 개발은 교사들의 적극적인 참여와 교육과 관련된 주요 이해당사자들이 폭넓게 참가하지 않고서는 성공하기 어렵다. 이러한 수업 평가기준 개발의 성공 여부는 이러한 평가기준이 일반 공동체, 특히 교육 공동체에 의해 수용되는 수준에 따라 결정될 것이다.
