The design of driver's cab includes the structure of cab frame, the layout of driver's cab equipment and facilities, i.e. driver's desk, seat, windows, floor, interior equipment, cab partition etc. The concept applied to the detail design has to be based on the ergonomics to guarantee the safety, comfort, and easy operation for the driver. In the aspect of manufacture, one more factor 'modulization' has to be considered into the design of sub blocks for cost-down. The design has to be implemented in the space allocated for driver's cab, which space is directly determined by the cab frame, optimized for the layout of driver's cab. The design process and results of the driver's cab for KHST will be described in this paper.

This paper introduces a novel concept of 'Emotional Communication' for future smart phone. While traditional information based communication technologies focus on how to precisely transmit the content of message, emotional communication is intended to support and augment social relationship among people and to comfort the user to be happy. In this paper, we propose future communication services and core technologies which can estimate emotional desire of users and respond to the desire to be happy with connectedness and consolation from peoples. Firstly, we introduce emotion recognition techniques to estimate emotional desire of users. At second, the emotional responding services are categorized to four parts and the details are shown. Lastly we propose the process to implement emotional communication system and the main techniques to fulfill the system requirements for future smart-phone services.

Applying human engineering simulation to analyzing work capability and movements of operators during manufacturing is highly demanded. However, difficulty in modeling digital human required for simulation makes engineers to be reluctant to utilize human simulation for their tasks. This paper addresses such problem on human engineering simulation by developing the technology to automatize human modeling with multiple Kinects at different depths. The Kinects enable us to acquire the movements of digital human which are essential data for implementing human engineering simulation. In this paper, we present a system for modeling automation of digital human. Especially, the system provides a way of generating the digital model of workers' movement and position using multiple Kinects which cannot be generated by single Kinect. Lastly, we verify the effects of the developed system in terms of modeling time and accuracy by applying the system to four different scenarios. In conclusion, the proposed system makes it possible to generate the digital human model easily and reduce costs and time for human engineering simulation.

The extremely strong competition among the world automobile industries has introduced the concept of PLM in the total production activities, one of whose major components is VM(Virtual Manufacturing). If the production lines are equipped with robots, the application of OLP in the virtual space is fully mature. However, in the point of the investment's and the maintenance's view, there are always some activities, which can not be automated: for example, typically the manual welding for prefixing in the automobile body shop and the material loading. Process planning for these activities, therefore, are decided mainly by experiences, which caused many repeated rework of the processes and the inconvenience of the workers, and resulted consequently in the reduction of the productivity and the safety of the workers. In this paper, the optimal dimension of the welding gun and its handle position and the optimal working path is simulated and decided by use of DELIMN/IGRIP and DELMIA/Ergo and the working area modelized in the virtual workcell of DELMIA.

This study was carried out to minimize the lifting force of a two hinge type stand mechanism. This unit is designed for the display devices in order to enhance the ergonomics for effective height adjustment and maintenance at any preferred position. The unit will be very useful for the mechanism fabricated with a coil spring and disc springs as a torque generator. The maximum and the minimum torque value should be calculated initially for the smooth lift. And the reasonable torque distribution is necessary to prevent any auto lift and auto dropping at any position because the torque generated by coil spring is more sensitive than disc spring in tilting the position. Therefore, the analysis of the coil spring is requisite to issue the specific torque value depending on the distorted angle with securing reliability of a long time storage condition. After the theoretical torque value was calculated, the evaluation was carried out by making a proto-type sample, then distorted angle was updated by experiment. The result of this study can readily be applied to various units for the optimization of the smooth lift.

인간이 역사를 이루며 살아오면서 피복은 인간의 생활 수단으로서 빠뜨릴 수 없는 존재가 되었다. 사외 생활을 하면서 인간은 자신을 보호하고 남에게 자신의 이미지를 전달하고 자신의 욕구를 표출하면서 만족시키는데 있어 의복은 가장 중요한 역활을 하고 있고 인간 역시 그러한 것들을 의복에 의존하고 있는 것이다. 그러나 정상인을 위한 의복만 취급되어지는 시장에서 신체장애자들은 정상인보다도 더 세심하게 기능들이 고려된 의복이 필요함에도 불구하고 의복의 기능들을 생각하면서 의복을 선택할 수가 없다. 이러한 사앙들이 대두되면서 현대에 들어 신체 장애자 의복에 있어서 불편함을 없애고 보다 적합한 의복을 만들기 위한 연구가 진행되었다. 신체 장애자의 의복 연구는 Ward가 이 부분에 관심을 표명한 이후 임상 의사들에 의해 연구가 이루어지기 시작했다. 우리나라에서도 1976년 심성식의 한국 신체 장애자의 의복에 관한 연구를 기점으로 이 분야의 관심도가 높아지고 있으나 아직까지는 전반적으로 부족한 실정이다. 특히 위생적인 분야에서는 자료가 매우 부족하다. 이에 본 연구에서는 휠체어를 사용하는 하지 마비자의 체표 면을 떠서 기성복 패턴과 비교를 통해 보다 편안한 바지 패턴을 제시하고, 여름철에 많이 사용하는 직물로 바지를 제작하고 착용시킨후 인체 생리 반응을 분석하여 여름철에 쾌적한 바지를 알아 보았다. 이 연구를 통해 일반인과는 생활 자세가 다른 휠체어를 사용하는 하지 마비자와 일반인이 입는 기성복 바지를 착용 했을 때 생기는 불합리한 요소들을 고려하여 미적이고 기능적 및 위생적인 측면에서 신체 장애자에게 보다 적합한 바지를 제작하기 위한 기초 자료를 제공하고자 한다.값은 $f^{m}$ (p-1)-1 이다.

The origin of ${\alpha}$$_2$ peak was regarded as the detrapping process of ions trapped with 0.9[eV] deep originated from impurity-ion remained in the specimen during production process of the material, in the crystalline regions. The origin of ${\beta}$ peak was concluded to be due to the depolarization process of "C=0"dipole with the activation energy of 0.75[eV] in the amorphous regions.

Digital media has evolved in different areas as a result of the development of media and communications technology. The development of such media has also affected design in general as well as the design process systems focused on computer systems. Specifically, study of digital media design is based on a variety media and the development of computers due to social and environmental changes. Additionally, study is required on the convergence of variety of research including business, computer science, and human ergonomics. Nevertheless, most curricula in domestic universities are biased towards training practical manpower rather than creative/analytical manpower. For this reason, interchange between and study in multidisciplinary courses is desirable. Therefore, this study analyzes the curricula of departments of multimedia design of major universities and suggests enhanced curricula based on an analysis of the current state and understanding of the problem.

Designers often hesitate to decide the shape, size, and layout of a product. Though ergonomic principles and data are absolutely needed in this process, they don't have enough guidelines to refer. For the refrigerator designers, they also are not convinced of their decision: the vertical position of the freezing and refrigerating rooms, the height of shelves, the shape of door-handle, and etc. To support the refrigerator design, we applied several ergonomic methods to the evaluation of a refrigerator. EMG measurement was used to evaluate the load of user's lumbar muscle. Based upon the experimental EMG data, we developed a model to predict the relative load according to the height of refrigerator shelves. Two different layouts of a refrigerator, R/F and F/R style, were compared with the model. A three-dimenaional motion analysis method was used to evaluate the user's motion of using a refrigerator. Ten door-handles with the different shapes and positions were evaluated by tracking the rotations of the user's arm. Video protocol analysis was used to evaluate the user interface of a control panel in a refrigerator. Finally, we made several ergonomic design guidelines based on the facts found in this research and the anthropometric data of the Korean adults. The results of this study can be applied to the ergonomic design of a refrigerator.
