Two-wheeled motorcycles rarely use windscreen wipers in general. However, if two or more wheeled motorcycles with upper body employ windscreen wiper systems, clear visibility should be ensured regardless of weather conditions. The windscreen wiper systems include washers, defrosting, and demisting. As demands for the personal mobility are rapidly increased, the related global safety standards for motorcycles with upper body have been revised accordingly. Currently only EU regulations issue the provisions of windscreen wiper systems for L-category vehicles, which characterize two or more wheeled motorcycles. Therefore, in order to agree with international safety standards, it is necessary to revise KMVSS (Korea Motor Vehicle Safety Standards) for motorcycles. Here, KMVSS regarding windscreen wiper systems for motorcycles are studied considering the EU regulations. It is expected that the findings in this study are useful for future amendment of KMVSS.

Vehicle occupant postures are anticipated to vary more widely during automated driving and to become more significant in terms of the autonomous vehicle safety. Experimental and computational approaches are needed to investigate and evaluate occupant behaviors during automated driving in general. However the validity and effect of such occupant postures are unknown, thus it is necessary to examine occupant behaviors and injury countermeasures for various occupant postures. This study was focused on the development and evaluation of restraint system model for occupant behavior examinations in the first step according to autonomous vehicle occupant safety. The finite element models of dummy and restraint system were set up and simulation results showed overall model performance and safety tolerances of different reclined occupant postures during frontal impact loading.

The purpose of this study to examines the general concepts and principles of 'occupations' which is an important part of J. Dewey's theory of education, examines ways to apply them to infant education, In Chapter Ⅱ, I considered the concept and principle of occupations in Dewey. Dewey's concept of occupation is an activity in which educational institutions reproduce various forms of work performed in everyday social life, in which the main purpose of occupations is not in productivity but in continuous growth that is the overall development of experience. In these occupations that take place in the early stages of education, is more important the process of the activities rather than the outcome of the activities. In chapter Ⅲ, I tried to apply the occupations to infant education. Although Dewey did not actively apply the theory of infant education, his ideology of occupations gives a rich message to infant education. According to Piaget's cognitive developmental stages, infancy is the period of sensory stimulation and pre-manipulation. During this period, infants are interested in activities using sensory organs and muscles. Therefore, we should allow the child to take part in play as a voluntary recreation of adult work activities that occur in everyday life through occupations. In chapter Ⅵ, I discussed the specific operating methods and the roles of teachers. The teacher should be able to anticipate and control the behavior of the infants where they may not be able to take place, observe the interest of infants who are passive in the activity or disturb the class, and should be able to work together happily. Direct experience and occupations are needed in infant and child education. Although a variety of programs have been developed, it is difficult to accurately reflect the theoretical background and the characteristics of infants and toddlers, and it is not often the case that they operate properly in the educational field. The cause may seem plausible at first, but in reality it is often due to misunderstanding and misunderstanding of the principles of experience or occupations, the unfair expectations and interventions of parents, and the demonstration of educational institutions.

Recently hydrogen fuel cell buses have been deployed for the public transportations. In order to introduce buses fueled by hydrogen successfully, the research results of hydrogen bus safety should be discussed and investigated significantly. Especially, Korean government drives research in terms of various applications of hydrogen energy to replace the conventional fuel energy resources and to improve the safety evaluation. Thus it is necessary to examine vehicle crashworthiness under side impact loadings. This study was focused on the simulation result evaluation of full bus model and simplified bus model with hydrogen fuel tank module and mounting system located below floor structure due to the significance of bus side impact accidents. The finite element models of hydrogen bus, fuel tank system and side impact moving barrier were set up and simulation results reported model performance and result comparison of two side impact models. Computational results and research discussion showed the conceptual side impact framework to evaluate hydrogen bus crashworthiness.

This study aims to reveal the concept of one's own ‘actual experience’ (體驗) by comparing with the concepts of experience, occupation, and work, focusing on J. Dewey's idea. First, if the concept of ‘actual experience’ is defined from an pedagogical point of view, it can be organized into ‘process of accepting external stimuli through the whole body by directly and specifically contacting the object through the body such as human sensory organs and muscles’. The concept of ‘actual experience’ in Dewey's thoughts was compared and analyzed with ‘experience’, ‘occupation’, and ‘work’, which are similarly used. First, experience contains very comprehensive meanings, but ‘actual experience’ can be said to be a subset of 'experience' in that it is used quite limitedly. Second, occupation refers to acquiring certain principles of objects related to real life, while actual experience refers to acquiring some knowledge through it. Third, while work pursues physical results, experience pursues psychological or intellectual results, and the former expects material and economic rewards, while the latter expects educational rewards.

We carried out impact test and simulation of door trim in order to enhance simulation accuracy of full vehicle side impact. Each door trim was fixed at rigid wall and an impactor was thrown upon it with initial velocity Plastic material property and assembly structure of door trim were thoroughly investigated to develop an appropriate analysis model. Good correlation was obtained between test and simulation. Full vehicle simulation revealed that the effect of chosen parameters was significant for injury prediction.
