This study aimed to develop a systematic process for identifying components that need to be changed to reduce the Head Injury Criterion (HIC) during pedestrian headform tests. Through simulation and analysis, it was confirmed that the hood, hinge, hinge plate, cowl, fender, and fender bracket significantly influence HIC15. The study identified the specific impact of each component on HIC15, allowing for targeted improvements. The proposed process demonstrated superior performance compared to single-component optimization, yielding more significant reductions in HIC15. Multiple vehicle models were tested, confirming the process's effectiveness in consistently lowering HIC15 values.

This study chiefly aims to clarify important items to establish design guidelines for the habitability of temporary housing. Though prevention of occurring disasters would be the best way, readiness for the protection of suffering psychological damage is essential to construct emergency shelters and temporary housing. Temporary housings until now have raised second psychological injury, due to the lack of community spaces between victims by the disasters. It is meaningful to make fundamental data for establishing design guidelines for the habitability of temporary housing through the advanced countries for the disaster protection.

The environment has increasingly attracted attention and fashion brands need to use new growth models by developing eco-friendly products, along with the drastic climate change. This study drew design guidelines from the factors of clothing disposal and reuse to propose ways to extend the longevity of clothing. It sets the design goals for the longevity extension of clothing as flexibility, originality, durability, and adjustability and drew a specific design guideline. The design methods used to achieve such goals are as follows. First, the design that is flexible in terms of physical changes needs to increase its activity and to be changeable, by applying pleats, rubber bands and elastic materials to the parts with many physical changes and movements. Second, it is necessary to reinforce the brand identity, create design that is flexible in terms of fashion and design very rare and attractive products, for the goal of original design beyond fashion. Third, it is necessary to increase the quality of clothing and improve the durability which can be decreased by washing and wearing. Fourth, it is necessary to create the design that can produce various styles, preserve the state of clothing and maintain its hygienic conditions by using removable detailed designs, shape-transformation designs and the designs which can be adjusted to climate changes and states, for the goal of adjustable design with better functionality. The findings provide ideas for fashion experts to pay more attention to the extending the longevity of clothing products and to develop eco-friendly designs and strategies.

Electronic Charting systems (ECS) in yachting and boating are the non-professional counterparts to ECDIS in commercial shipping. In the absence of legal regulations on design and use, a wide variety of products have de-veloped. Their usability is not only safety critical but often even determines whether navigation functions like route building or track recording are used at all. With two empirical studies employing standard usability meth-ods from human factors research, we assessed the usability of a variety of current ECSs on a sailing yacht. In study 1, nine usability experts conducted multimethod analyses while sailing in typical cruising areas on sea. Building on the results, a standardized user test was designed and carried out with 12 prototypical users plus 3 usability experts in inland waters (study 2). Finally, a set of 38 design and usability guidelines were formulated. The guidelines may not only help boat owners and charter companies in selecting a current market product but also aid manufacturers in designing their future products. Contributions: David Jung (study 1) and Martin Müller (study 2) conducted the studies and formulated the guide-lines. Gisela Müller-Plath designed and managed the research project ANeMoS (Analysing Use and Impact of NewMedia on Sailboats) which the present work is part of, commanded the sailing yacht, and wrote the paper.

PURPOSES :This study proposes standards for rural access road pavement section and thickness design considering existing access road construction conditions; the study also proposes a complementary policy that can be used for design convenience.METHODS:Various literature review and case studies had been performed in terms of rural access road section and thickness design, both domestically and internationally, and this was followed by domestic rural access road field surveys. KPRP and KENLAYER were used to analyze the commonalities and predict the remaining life. Data on real cost is used to select an appropriate construction method through economic analysis.RESULTS:The economic efficiency of concrete pavement (15×15) was the highest in terms of economic efficiency of performance life and traffic volume. In the case of asphalt pavement, it is considered that the most economical method is to implement micro-surfacing method four times as a preventive maintenance method (once every 10 years and 4.5 years for asphalt concrete pavement and MS construction method, respectively). Repairable asphalt pavement is advantageous for areas where heavy vehicles are expected to pass. In the case of other general areas, it is considered economical to place concrete (15×15) pavement. However, as analytical results on its performance life are unavailable, it is to be considered for study in the future.CONCLUSIONS :This study proposed interim design guidelines based on various domestic and international design guidelines and case studies. However, in order to develop the final design criteria applicable to the field, it is necessary to (a) estimate the bearing capacity of the lower level of the pavement at various sites, (b) estimate the daily traffic volume, (c) implement advanced low-cost pavement technologies, and (d) propose maintenance standards and techniques for long-term performance.

PURPOSES: Design of approach roads of rest areas in highway has many drawbacks such as geometric design elements. There has been traffic accidents occured in these approach roads of rest areas. Thus, design criteria is required in order to protect accidents from being occurred. In case of Korea, geometric structure design criteria of entry facilities, such as toll-gate, interchange, junction etc was established. However there are no presence in a detailed standards for geometric structure of the rest area which affiliated road facilities. METHODS: In this study, analytic on accidents was carried out in regards to the entry of geometric structure of resting areas by utilizing a sight survey and an investigation research of traffic accidents. The survey was targeting 135 general service areas. Collisions with physical channelization and safety facilities occurred due to speeding, rapid entry, and etc at the entrance nose section. At the entrance connector roads, accidents caused by speeding, negligence, over-operation of handle of drivers were main reason of accidents. Discriminant analysis were conducted about geometric elements to distinguish influencing factors for traffic accidents. the lengths and access angles of the entrance connector roads were regarded as to have the high relation with traffic accidents. RESULTS: After classifying the design section of resting areas' entry as well as derive design elements on each section, a speed measurement by targeting entry of rest areas and car behavior surveys were performed, then each element's minimum standard was derived through the analyses. According to the speeds at the starting/end point of entrance connector road, the range of the junction setting angle of the entrance connector road is defined as 12˚~17˚ and the connector length model was suggested. CONCLUSIONS: Suggest improvement plans for existing rest areas that can be applied realistically. This should be corresponded to the standards of entry and exit of developed rest areas.

휴게소 진 출입부는 설계속도 등이 급변하는 구간으로 교통안전 취약구간이며 특히, 휴게소 진입부는 감속과 주차공간 검색 두 가지 작업이 동시에 수행되므로 이용차량의 안전성을 확보할 수 있는 설계기준이 필요하다. 국내의 경우 영업소나 나들목, 분기점 같은 출입시설에 대한 기하구조 기준은 수립되어 있는 반면, 도로의 부속시설인 휴게소에 대한 상세한 기하구조 기준은 없는 실정이다. 이에 본 연구에서는 일반형 휴게소 135개소를 대상으로 한 현장조사 및 사고조사 자료를 활용하여 휴게소진 출입부 기하구조에 대한 문제점을 도출하였다. 휴게소 진 출입부의 설계구간을 분류하고 각 구간에 대한 설계요소를 도출한 후, 휴게소 진 출입부를 대상으로 속도조사 및 차량주행행태 조사를 수행하고 분석을 통해 설계요소별 최소 기준을 도출하였다. 진입 연결로의 시/종점 속도에 따라 감속거리 산정식을 이용하여 진입 연결로의 최소길이는 40m를 제안하였고, 주행행태를 기반으로 선형 안전성 평가를 통해 접속 설치각은 12~17˚를 제안하였다. 개발된 휴게소 진입부 설계기준은 신설되는 휴게소 뿐만 아니라 기존 휴게소에 대해 현실적으로 적용 가능한 개선방안을 제시할 수 있을 것으로 판단된다.
