This paper proposes a single-joint optical torque sensor with one body structure. Conventional optical torque sensors consist of three parts, two plates and an elastic structure. They have slightly slipping problem between plates and elastic structure due to the manufacturing tolerance. Since the order of measurement range of optical sensor is about ten micrometers, the slipping problem causes large measurement error, especially in the case of vibrational or high speed plant. This problem does not occur in the proposed design due to the one body structure. The proposed sensor has advantage of low cost, light weight, and small size. And it is easy to design and manufacture. Simulation works that analysis of stress and strain are performed accurately. To demonstrate the performance of proposed sensor, experiments were implemented to compare with a commercial force/torque sensor (ATI Mini45).

EasySoft(이하:ES)는 컴퓨터를 처음 배우는 초급자에서부터 프로그래밍 가능자에 이르기까지 다양한 범위의 학습자에게 통합 교과적인 지식을 토대로 알고리즘 교육을 제공하여, 창의성과 논리성 계발의 효과를 거둘 수 있도록 만들어진 학습기자재이다. ES는 EasyLab, EasyC, Visual Basic과 같이 ActiveX를 지원하는 툴과 연동하여 사용한 수 있는 ActiveX 제어도구(EasyOCX)로 구성되어 있다. 학습자는 ES를 통하여 자신의 생각을 구성, 알고리즘화 시켜 프로그래밍하고 코드를 로봇으로 전송하여, 로봇의 움직임과 자신의 의도를 비교, 연구, 반복하는 작업으로 학습하게 된다. ES는 학습기자재가 부족한 교실현장에서 직접 활용할 수 있도록 구성된 것으로, 흥미적 요소와 교육적 요소를 적절하게 조화 시킨 소프트웨어이다. EasyLab은 컴퓨터를 모르는 학습자도 알기쉬운 GUI식 흐름도 기반 S/W를 표방하므로 초등학교에서, EasyOCX나 EasyC의 경우는 EasyLab과 유사한 방식을 추구하되 직접 프로그래밍 하게 되어있어 한 단계 높은 중 고등학교의 교수장면에서 직접 활용이 가능하다.

This research aims to evaluate how each generation experiences easy payment services. Recently, the easy payment service business has been on an upward trajectory and pin-tech companies have introduced various types of products. In this regard, it becomes crucial to understand differences among generations in terms of using those services due to their accessibility and serviceability. Based on the statistical analysis of surveys and in-depth interviews based on Peter Morville's Honeycomb model, this study suggests four ways to improve this payment service. The analysis indicates that those who are older tend to use easy payment services provided by their credit card companies or services which they frequently have already used. Findings of this analysis are expected to find the relationship between ages and payment applications.

The configuration of injection molded part can be classified into primary feature and supplementary feature. Even though supplementary features such as ribs, snap fits and bosses make mold more complicated, which cause the increasement of the mold cost, supplementary features should be attached to primary features because of assembly, reinforcement, moldability and other functional purposes. But it is not easy for novice designers to design them appropriately because of the profound knowledge related to Injection molding. In this paper, the intelligent design tool called ISFD(Intelligent Supplementary Feature Designer) which supplies easy, simple, time and cost-effective design method has been studied and developed. A knowledge-based design system is a new tool which enables the concurrent design and CIM with integrated and balanced design decisions at the initial design stage of injection molding.

This study suggested the environmental components for open space in a healing environment based on the social support approach for integrating and enhancing users' activities and interactions. The physical environments of the open space in healing facilities should be suggested by social support design and support the interactions of various users. Particularly architectural environment conditions should reinforce the contribution to the revitalization of medical facilities based on improving the healing effect of patients through mutual exchange of users. The open space environment conditions influence users' healing process with physical design factors and users' interactions, and the flexible environments based on the social support that is crucial for circulation and mutual exchange of users. The open space transformation, integration of technology, and wayfinding system with color and signage also allow users to improve the space experience and easy access. The environmental components of open space design should include easy access for user inflow, flexible layout for comfort, access to outdoor spaces, integration of warm color schemes for relaxation, personalization of spaces with artwork, and visual interest through the use of textures and materials.

In line with the "mandatory seismic design of fire protection facilities," development of design automation software is indispensable for improving the reliability and efficiency of seismic design. The seismic design automation software developed in this study is an automated S/W for seismic design of fire-fighting facilities, and functions such as automatic arrangement of anti-shake braces according to Korea National Fire Agency's Seismic Design Standards for fire-fighting facilities, output of seismic bracing calculation bills and automatic quantities counting. In addition, the seismic design automation software not only reduces the work speed by three times compared to the manual design of the designer, but also improves the reliability of the design by reducing the human error related to the design quantity such as the brace. In addition, in the seismic design method of fire protection facilities that have been approached conservatively, it was possible to perform the optimal seismic design by using computer algorithms for at least in the use of braces.

Purpose In this study, the difficulties were analyzed with the field data from two domestic and interview with industry practitioners. And We presented initiatives with feasibilities to overcome the hurdle for progress of easy-payment. Design/methodology/approach We collected industry data from two domestic credit card companies and analyzed that data to prove 7 proposition in detail. Also We had interview data from industry practitioners who can understand the relationship between stakeholders. For this analysis, we used the causal loop diagram to find activation inhibition and activation elements about easy-payment. Findings The Fintech easy-payment industry has been organically involved in various partners such as customers, merchants, PGs, VANs, credit card issuers, banks, payment providers, terminal manufacturers, etc. and they have been competing against each other to hold leader position in the easy-payment market. Because of the reasons, the easy-payment does not spread out as much as it expects. In this study, the difficulties were analyzed with the field data and interview with industry practitioners and proposed five initiatives with feasibilities to overcome the hurdle for progress of easy-payment. This study helps to understand current situation and issues of Fintech and easy-payment for related research in future.

A knowledge-based system with CAD is widely used to implement a designer's know-how and a routine calculation within a system. An engineer needs to change several design parameters in an early design stage. However it is not easy to change the design parameters when it needs to update an existing model and data. In this paper, a module has been proposed to make it easy to change the design parameter so that the engineer can easily update and change the design model. Also a flexible interface of the module can easily add or extract the design knowledge.

The purpose of the present study is to develop an analysis model to analyze the design parameter sensitivity of a high-power drifter suitable for implementation in Korean hydraulic drills. This study aims to establish a basis for the optimization of the impact performance and stability of a high-power drifter by investigating the effects of each design parameter on the impact performance via design parameter sensitivity analysis. To begin, an analysis model of drifter dynamics is developed, and the reliability of the analysis model is verified by comparing the analysis results to the experimental results. The drifter is then redesigned for compatibility with Korean hydraulic drills. Finally, design parameter sensitivity analysis of the redesigned drifter is conducted to determine the effects of the design parameters on the impact performance, and to extract the high-sensitivity parameters. SimulationX, which is multi-physics analysis software, is used to develop the analysis model, and EasyDesign is employed for design parameter sensitivity analysis.
