This paper has develops a new framework to understand the human’s driving maneuver based on the expression as HDS focusing on the driver’s stopping maneuver. The driving data has been collected by using the three-dimensional driving simulator based on CAVE, which provides three-dimensional visual information. In our modeling, the relationship between the measured information such as distance to the stop line, its first and second derivatives and the braking amount has been expressed by the PWPS model, which is a class of HDS. The key idea to solve the identification problem was to formulate the problem as the MILP with replacing the switching conditions by binary variables. From the obtained results, it is found that the driver appropriately switches the ‘control law’ according to the following scenario: At the beginning of the stopping behavior (just after finding the stopping point), the driver decelerate the vehicle based on the acceleration information, and then switch to the control law based on the distance to the stop line.

This study divided all cooking-related employees into hotel organization and family restaurant organization, and analyzed the present duties´ characteristics along with an analysis on population statistics. Also, the study examined each employee´s recognition degree of his/her duty in each group and investigated which knowledge and skill they thought as important parts for their developing ability and attaining duties in the future. The collected data tell the followings; with respect to the characteristics of the employees´ duties, the characteristics of hotel employees were different from those of family restaurant employees; in case of hotel employees, the characteristic items recognized at a high level were the importance of duty, independence, self-reliance, the knowledge degree, career, controlling-ship, and development-ship. On the contrary, in case of family restaurant employees, the highly recognized items were complexity of duty, stagnation-ship, and human relationship. Generally, it was clear that family restaurant employees showed more complaints than hotel employees did in the section of recognition degree on the present duties. The imperfect matter is that this study could not specify particulars or details of knowledge and skills that are necessary to make a perfect food-service company. However, this study will become a basis to develop further research on a perfect supposition and detailed particulars by detailed variables in a demonstrative way.

It was maintained that successful establishment and accomplishment of outsourcing might be possible only when those eating-out companies re-establish their concept of management strategy, identify core competencies through value-chain analysis, make a through cost analysis, select cooperative companies via overall screening, expand the area of outsourcing, enhance partnership to improve service quality, harmonize bilateral organization culture, remove the ambiguity of contract terms, protect core competencies of the rest area, continue with evaluation and control, and spinoff or invest to a new specialized business. Then, it was suggested that highway rest area business construct the core competencies and introduce outsourcing from a future-oriented viewpoint so that they can concentrate the competencies to competitive area and expand outsourcing scope to professional area such as finance and accounting, general affairs, personnel affairs, logistics, marketing, and R&D. They need to make out the problem of productivity reduction resulted from many years working employee's old age, refine human resource, and maintain the standards of skill so that they can improve service quality of the rest area, streamline each organization currently having so a large manpower, reduce manpower, and improve the productivity.

Repetitive stress injury at the wrist has been reported as a common injury among visual display terminal (VDT) users (i.e., computer users). Adjusting a VDT workstation (computer table and chair) to maintain a correct seated posture while operating a keyboard is perhaps the most frequently recommended preventive solution. This paper proposes an analytical design methodology based on ergonomic design principles for recommending appropriate VDT workstation settings and layout of individual computer accessories on the computer table. The proposed design methodology consists of two interrelated phases: (1) determination of VDT workstation settings, and (2) design of computer accessories layout. Based on the information about the VDT user, dominant task to be performed, typing skill, and degrees of physical and visual interactions between the user and computer accessories, adjustment and layout solutions are recommended to allow having a correct seated posture while minimizing both physical and visual movements. The results from an experiment show that when adjusting the workstation and locating the computer accessories according to the recommendations given by the proposed design methodology, the user's hand movements can be significantly reduced.

This study is a review on the relationship between furniture purchasers and producers in the Joseon period. Understanding the relationships in our traditional spirit and the Joseon furniture that reflects a aesthetic sense is a meaningful work. Joseon was to build an ideal country which put emphasis on the order and harmony through Theory of 'Yeak' as the confucianism nation. Human aesthetics, which emphasis on the spiritual value by confirmity to nature and forcus on the relaxed, deficient personality rather than completeness was established as the central formative consciousness of the Joseon Dynasty. The nature of things in the confucian scholar prior to the representations of things is expressed in the form of master craftsman's skill and soul. Formative consciousness of the confucian scholar is to realize ideals by communciation and interchange with master craftsman's soul in the form of the Joseon furniture. The beauty of restraint and brevity in the Joseon Dynasty furniture includes meanings and procedures of art work. It implies an orderer's purpose of production and a producer's products. Understanding the spirit of times in the production becomes the cornerstone capable of getting closer to the furniture ultimate proper function. These problems have a very close relationship with the problems of modern people's commnuication. We expect an even higher growth of the furniture by achieving more improved communication based on the consumer's great insight and the producer's passion.

Eyewear must not be judged only by the skill of the designer who created it. For production of successful eyewear, we must always take into account the point of view of the wearer. Because eyewear is above all a means to correct of the visual acuity, it is a medical instrument. Therefore in any case, it should not submit to the dictatorship of fashion designer. The eyewear designer's role may therefore be summarized in following way: to have a subtle sensitivity and inspiration, and originality, know-how to develop a symbiosis between functionality and technical know-how, harmonious production of the design and concept of the human engineering. At present, the way of designing has undergone a big change to enabling us to supply the customer with technical design and rapid prototyping of eyewear with assistance to computer processing such as computer graphic and cad/cam.

The velocity dipole field method is presented for real-time collision avoidance of mobile robots. The direction of motion of the obstacle is used as the axis of the dipole field, and the speed of the obstacle is used to proportionally strengthen the dipole field. The elliptical field lines of the dipole field are useful to skillfully guide the robot around obstacles, quite similar to the way humans avoid moving obstacles. Field modulation coefficient is also introduced to weaken the field effect as the obstacle recedes. The real-time algorithm of the velocity dipole field has been devised and experimentally tested on the robot soccer test-bed. The results show the capability of the new real-time collision avoidance strategy and how it can overcome the weaknesses in the conventional potential field method. The new method makes an explicit and proactive action of collision avoidance, unlike the conventional method, which forces the robot merely away from the obstacle aimlessly. The proposed method delivers greater capability with no considerable computational overhead

This research is looking for the relation between the positive psychology of would-be child teachers and leadership and that's influence. The researchers examined positive psychology and leadership with 330 would-be teachers(13 boys, 317 girls) located in Gwang-Ju and the Jeonnam Region. Questionnaire was used to measure would-be teachers. The collected data analyzed the positive psychology of would-be teachers and leaders, including sub-factors for mean(M), standard deviation(SD) and Pearson product-moment correlation according to subject for inquiry. Then regression analysis through SPSS WIN 17.0 for checking the effects of the would-be child teachers's positive psychology with their leadership skill was used. The result of the research was that the positive psychology of would-be child teachers and leadership of the product-moment correlated in all areas. Especially the most influence on positive psychology is the ability of human relationship among leadership sub-variables, and the relation between positive psychology and leadership are very important for making positive changes in society. This implies that there is a need for more educational sponsorship regarding positive psychology and leadership for would-be child teachers.
