The vehicle simulator is a useful virtual reality system. The simulator enables engineers to effectively research and analyze various experiments. Therefore, the development of a specific vehicle simulator is required, and its performance must be verified. This paper verifies the performance of Pusan National University Vehicle Simulator. Human sensibility ergonomic tests of vehicle simulator were also executed. The sense of simulator motion was chosen as the standard of performance evaluation. The driver's senses were subdivided into senses of rectilinear and rotational velocities. This study extracted ergonomic sensibility words that can be used to evaluate the performance of the simulator As a practical application of simulator, the relation was studied between the sense of simulator motion and the characteristics of drivers, who are classified into their sexes and driving careers. A statistical method was applied to human sensibility ergonomic tests of vehicle simulator.

This paper describes a technique for human sensibility evaluation using EEGs of 4 emotions. The proposed method uses the linear predictor coefficients as EEG feature parameters and a neural network as sensibility pattern classifier. For subject independent system, multiple templates are stored and the most similar template can be selected. EEG signals corresponding to 4 emotions such as relaxation, joy, sadness and anger are collected from 5 armature performers. The states of relaxation and joy are considered as positive sensibility and those of sadness and anger as negative. The classification performance suing the proposed method is about 72.6%. This may be promising performance in the human sensibility evaluation.

소리나 음악을 '감정, 감성의 언어'라고 표현한다. 이것은 소리라는 물리적 속성들이 인간의 감성 정보를 효과적이고 풍부하게 전달하는 좋은 수단일 수 있기 때문이다. 하지만 정보의 청각적 제시에 대한 효과적 방안을 연구하는 청각 디스플레이(auditory displays) 분야의 연구자들은 주로 특정 시스템 사용자의 과제수행 결과의 효율성 증진에만 초점을 맞추어 왔었다. 이러한 한계점을 극복하고 청각적 정보 제시의 적용 영역을 확장하고자 최근 많은 연구자들이 과제수행 결과뿐 아니라 개인의 선호와 감성적 만족이 더 중요한 요인이 될 수 있음을 지적하고 있다. 이런 배경으로 본 연구에서는 소리에 대한 감성어휘 수집과 분석을 통해 소리의 감성공간을 '즐거움(Pleasure)', '복잡성(Complexity)', '활동성(Activity)'의 세 개 차원으로 구축하고, 그 차원에서 음고(pitch), 음량(loudness), 음색(timbre), 그리고 지속시간(duration)과 같은 소리의 다양한 속성에 따른 감성의 이동을 체계적으로 살펴보았다. 그 결과, 각 차원들에서 소리의 여러 속성들에 따른 감성적 차이와 그 상호관계를 확인하였다. 결론적으로 이러한 결과들은 청각 사용자 인터페이스(Auditory User Interface)와 같이 청각 디스플레이(auditory displays) 분야에 적용되어 소리의 속성에 따라 감성 정보를 응용하여 사용자의 특성과 요구에 맞춰 정보를 제시하는 데 기여할 것이다.

This paper describes a technique for human sensibility evaluation using 10-channel EEG(electroencephalogram). The proposed method uses the linear predictor coefficients as EEG feature parameters and a neural network as sensibility pattern classifier. For subject independent system, multiple templates are stored and the most similar template can be selected. EEG signals corresponding to 4 emotions such as, relaxation, joy, sadness and anger are collected from 5 armature performers. The states of relaxation and joy are considered as positive sensibility and those of sadness and anger as negative. The classification performance using the proposed method is about 72.6%. This will be promising performance in the human sensibility evaluation.

The purposes of this study ate to evaluate sensibility performance of metallic Jacquard fabrics, and to contribute to the research and development of the women's suit made of the metallic Jacquard fabrics. eight fabrics were woven with two kinds of warp yarns(nylon and rayon) and weft yarn blended with various contents(0, 7, 14, 21%) of metallic yarn. The sensibility performances such as sensory, touch preference and buying preference for memory fabrics of the metallic Jacquard fabrics were evaluated, and mechanical properties were measured by KES-FB system. The correlation between the mechanical properties and the sensibility performance were analyzed. As the metal fiber content increased, the sensory evaluation value of lustered, wrinkly, sandy, rustle and stiff increased, the sensory evaluation value of slippery and damp decreased. As the metal fiber content increased, the touch preference decreased and the buying preference increased. The touch preference had negative correlation with the metal fiber content, but the buying preference had positive correlation with it.

This study presents a human sensibility evaluation method using neural network and multiple-template method on electroencephalogram(EEG). We used a multi-layer perceptron type neural network as the sensibility classifier using EEG signal. For our research objective, 10-channel EEG signals are collected from the healthy subjects. After the necessary preprocessing is performed on the acquired signals, the various EEG parameters are estimated and their discriminating performance is evaluated in terms of pattern classification capability. In our study, Linear Prediction(LP) coefficients are utilized as the feature parameters extracting the characteristics of EEG signal, and a multi-layer neural network is used for indicating the degree of human sensibility. Also, the estimation for human comfortableness is performed by varying temperature and humidity environment factors and our results showed that the proposed scheme achieved good performances for evaluation of human sensibility.

Simulators have been used to evaluate drivers'reactions to various transportation products. Most researches, however, have been concentrated on their technical performance, thus this paper considers drivers'senses of moving on a vehicle simulator through the analysis of human sensibility ergonomics. A sensibility ergonomic method is proposed in order to improve the faithfulness of vehicle simulators. A simulator of passenger vehicle consists of such three modules as vehicle dynamics, virtual environment, and motion representation modules. To evaluate drivers'feedback, human feelings are categorized into a set verbal expressions collected and investigated to find the most appropriate ones for translational and angular accelerations of the simulator The cutoff frequency of the washout alter ill the representation module is selected as one sensibility factor Sensibility experiments were carried out to find correlation between the expressions and the cut-off frequency of the filter. This study suggests a methodology to obtain an ergonomic database which can be applied to the sensibility evaluation of dynamic simulators.

The purpose of this study is to verify the relationship between the entrepreneurship and management strategy perceived by the members of SMEs and their organizational performance. First, as a result of the hypothesis that the entrepreneurship of one hypothesis had a significant influence on organizational performance, risk sensibility, progressiveness, and innovation, which are entrepreneurship, had a positive influence on both financial and non-financial performance. Second, as a result of verifying the influence relationship of the hypothesis two entrepreneurship on the management strategy, risk sensibility, progressiveness, and innovation, which are entrepreneurship, were statistically significant for the management strategy, cost advantage strategy, differentiation strategy, and centralization strategy. Therefore, in order to practice management strategy based on entrepreneurship, it was analyzed to influence mutual cohesion. Third, the management strategy showed a positive influence on organizational performance. In particular, only the centralization strategy, a type of SMEs' management strategy, confirmed the positive impact on the financial and non-financial performance. Therefore, the importance of entrepreneurship and management strategy has been emphasized in order for SMEs to create organizational performance through the advancement of sustainability management system.
