In this paper, we propose the ergonomics design method in shape design applicable which considers the user interface for railroad. This study focuses on ergonomics design and sensibility engineering design, user interface, which should be considered from the conceptual design stage of the rolling. Human's sensitivity and User Interface of railroad investigated ergonomics studies of several type. The sensibility engineering design made approach of user center design in railroad design. New design railroad to satisfaction passenger's various desire, to safety and convenient through high technology, to sufficient passenger's aesthetic sense. Therefore, we have application to properly of ergonomics design element in railroad design. we expert visual design and user interface help greatly in excellent railroad design.

With the increasing availability of high-performance computing (HPC) platforms, uncertainty quantification (UQ) and sensitivity analyses (SA) can be efficiently leveraged to optimize design parameters of complex engineering problems using modeling and simulation tools. The workflow involved in such studies heavily relies on HPC resources and hence requires pre-processing and post-processing capabilities of large amounts of data along with remote submission capabilities. The NEAMS Workbench addresses all aspects of the workflows involved in these studies by relying on a user-friendly graphical user interface and a python application program interface. This paper highlights the NEAMS Workbench capabilities by presenting a semiautomated coupling scheme between Dakota and any given package integrated with the NEAMS Workbench, yielding a simplified workflow for users. This new capability is demonstrated by running a SA of a turbulent flow in a pipe using the open-source Nek5000 CFD code. A total of 54 jobs were run on a HPC platform using the remote capabilities of the NEAMS Workbench. The results demonstrate that the semiautomated coupling scheme involving Dakota can be efficiently used for UQ and SA while keeping scripting tasks to a minimum for users. All input and output files used in this work are available in https://code.ornl.gov/neams-workbench/dakota-nek5000-study.

One of the difficulties in using the current Boolean-based information retrieval systems is that it is hard for a user, especially a novice, to formulate an effective Boolean query. One solution to this problem is to let the system formulate a query for a user from his relevance feedback documents in this research, an intelligent query reformulation mechanism based on ID3 is proposed and the sensitivity of its retrieval effectiveness, i.e., recall, precision, and E-measure, to various input settings is analyzed. The parameters in the input settings is the number of relevant documents. Experiments conducted on the test set of Medlars revealed that the effectiveness of the proposed system is in fact sensitive to the number of the initial relevant documents. The case with two or more initial relevant documents outperformed the case with one initial relevant document with statistical significances. It is our conclusion that formulation of an effective query in the proposed system requires at least two relevant documents in its initial input set.

This paper proposes an optimal design software for the open-chain dynamic systems whose governing equations are expressed as differential equation. In this software, an input module and an automatic creation module of the equation of motion are developed to contrive the user's convenience. To analyze the equation of motion of the dynamic systems, variable-order and variable-stepsize Adams-Bashforth-Moulton predictor-corrector method is used to improve the efficiency. For the optimization and the design sensitivity analysis, ALM(augmented lagrange multiplier)method and adjoint variable method are adopted respectively. An output module with which the user can compare and investigate the analysis and the optimization results through tables and graphs is also provided. The developed software is applied to three typical dynamic response optimization problems, and the results compare very well with those available in the literature, demonstrating its effectiveness.

This paper introduces a novel concept of 'A Green LED Sensitivity Lighting System' which can automatically estimate QoS(quality of service) and emotional requirements of user using smart phone. And it can intelligently control ambient illumination lamp to conserve electric energy and to satisfy human sensitivity. The proposed system has 4 control modes; emotional lighting, smart lighting, green lighting and realistic lighting modes in order to comfort man's emotion, to maximize work efficiency, to save energy consumption and to make the entertainment more fun, respectively. When we choose green lighting mode for indoor office situations, an elaborate simulation shows that the proposed system with home network can reduce the energy by 50% compared to conventional light control system with a fixed time-based switching.

In this paper, we present a method for smartphone users to have a better user experience when playing 3D mobile games using the gyro sensor. We designed the rotation of the virtual camera in the game world to be proportional to the real-world's rotation. We have also made the sensitivity configuration possible for users to manipulate.

최근 일 중심에서 여가 중심으로의 가치관의 변화는 사람들의 삶의 양식을 변화시키고 있다. 이러한 시대에는 스포츠 활동 참여가 현대인의 삶의 질을 향상시키는 중요한 수단으로 여겨지게 된다. 시대적 변화에 따라 사람들의 카약을 비롯한 수상 레저스포츠 참여가 증가하고 있다. 이에 따라 소비자들의 다양한 수상 레저용품 디자인에 대한 욕구가 늘어가고 있는 변화에 적극적으로 대응할 수 있는 전략이 필요하다. 본 논문에서는 레저용 카약 디자인 설계를 위한 사용자 의사결정 지원 시스템을 제안한다. 이를 위하여 기존 연구 및 문헌, 소비자 설문조사를 통해 카약 디자인 관련 감성을 선정하고, 요인분석과 평가로 감성을 도출하여 고객 감성 선호측면에서의 카약 디자인 배열을 제시하였다. 본 연구의 결과는 카약설계 뿐만이 아니라 수상레저스포츠의 기구의 다양한 디자인 가이드로 활용될 수 있으며, 사용자 중심 설계의 기반으로 활용될 수 있을 것이다.

현재 기술발전에 따라 급변하는 제품의 패러다임은 다양화 되어가는 사용자의 감성적 니즈의 변화와 밀접한 관련이 있다. 이것은 사용자들이 제품의 규격화 된 형태와 편리성을 강조하기보다는 감성적 가치 부여를 지향하고 있기 때문이다. 이러한 감성적 가치는 사용자의 제품에 대한 니즈로 연결되고, 궁극적으로는 제품의 구체적인 속성에 의해 충족될 수 있다. 창의성은 디자인 분야뿐만 아니라 미래사회에서 가장 중요한 경쟁력을 갖게 하는 요소로 대두되고 있다. 그리고 디자이너는 주어진 것에 순응하는 사람이 아니라 끊임없이 새로운 지식과 가치를 창조해 나가는 지식 노동자이며, 경쟁력에서 이길 수 있는 가장 부가가치 있는 부분이 창의성이라 할 수 있다. 결국 창의적 디자인은 사용자에게 심리적 감흥을 불러일으켜 기존 제품들과는 차별화된 새로운 디자인 해결안으로서 그 가치를 인정받는 것이다. 본 연구는 창의적 디자인에 있어 사용자의 의식 또는 무의식의 니즈에 대하여 디자인 구성요소와 심미성 요소를 파악하여 차별화된 창의적 디자인의 제품 개발에 있어 구체적인 디자인 요소를 설정하고 심미성 요소를 통한 디자인 컨셉 도출 과정에 활용될 수 있는 가이드라인을 제시하고자 한다.

GPS which measured user's location information outdoors should be of poor sensitivity because of interference and jamming of different electromagnetic waves. Specially, it has a defect of low received rate in high-rise urban where reflection and refraction of satellite signal go well. In this paper, I propose user location information sharing modeling of both vehicle and mobile phone using bluetooth in urban.

We propose a semi-automatic and dynamic indexing algorithm for multi-media database(e.g. movie files, audio files), which are difficult to create indexes expressing their emotional or abstract contents, according to user's sensitivity by using user's histories of access to database. In this algorithm, we simply categorize data at first, create a vector space of each user's interest(user model) from the history of which categories the data belong to, and create vector space of each data(title model) from the history of which users the data had been accessed from. By continuing the above method, we could create suitable indexes, which show emotional content of each data. In this paper, we define the recurrence formulas based on the proposed algorithm. We also show the effectiveness of the algorithm by simulation result.
