  • Aircraft fuel indicator is a device to indicate the amount of fuel remained during flight, where accurate and consistent operation of the indicator should be maintained. Previously the Korean Utility Helicopter fuel indicator sporadically displayed abnormal sign by "8888" during flight, jeopardizing flight safety. Inappropriate EMI/EMC performance was detected during trouble shooting process. The cause of the abnormal display was found to be resulted from unstable power induced by electro-magnetic disturbance and CAN communication error. The aircraft fuel indicator design was improved and the design compatibility was verified to avoid abnormal display.

  • In this paper, we propose vehicle SoC fault diagnosis platform using FlexRay protocol in order to detect the faults of semiconductor control chip even after vehicle production. Before FlexRay protocol by sending NFI (Null Frame Indicator) bit among the header segment and a specific identifier in the payload segment of FlexRay frame, this technique can be distinguishable from normal mode and test mode. By using this technique, it is possible to detect the faults such as performance degradation of vehicle network system caused by the aging or several problems of vehicle semiconductor chip. Also high reliability and safety of vehicle can be maintained by using structural test for vehicle SoC fault detection.

  • With the development of synthetic dyes, excellent dyeing properties and massive production became possible. On the other hand, natural dyeing technology has gradually disappeared. However, the international environmental and human safety requirements of the apparel and textile industry are increasing, and there is a growing interest in safer and more environmentally friendly products. Accordingly, the public's interest in natural dyeing is increasing. To meet these demands, it is first necessary to clarify the stages of production and distribution of natural dyes. It is necessary to evaluate whether the product is a natural dye product and study the suitability of the natural dye product through qualitative and quantitative assessment of the indicator components of the natural dye. Typical of three natural dyes did qualitative and quantitative analysis by HPLC-DAD and HPLC-MS. Products dyed using natural dye three products were analyzed, and the presence or absence of detection of each indicator components was confirmed to confirm whether the product was dyed using natural dyes.

  • This paper presents 10 input measures influencing project outcomes. Construction Industry Institute (CII), a consortium of more than 130 project owner and contractor companies, has collected project-level data for over 20 years. Recently, CII has developed a new system measuring project-level performance and factors presumably influencing project performance. The system, called 10-10, collects data for 10 input and 10 output measures for capital projects. The input measures include planning, organizing, leading, controlling, design efficiency, human resources, quality, sustainability, supply chain, and safety. This paper provides theoretical background for these measures. Although the input measures have been known to impact on project outcomes such as cost and schedule, there has been no study quantitatively evaluating how they are operated in the construction industry. This study contributes to revealing the current status of their uses, which will be helpful in establishing strategies improving construction project performance.

  • The purpose of this study is to provide the fundamental data to improve a school building through comparing and analyzing facilities of high schools located in Gyeonggi - do Province on the basis of the Design Indicator for the Korean Educational Buildings. Two types of high schools were examined for this study. Some of them are high schools selected by Korean Ministry of Education as a school equipped with superior facilities and the others are high schools equipped with general facilities. 8 items such as safety, comfort, the function of education, utilization, the public, eco-friendliness, technology performance, economical efficiency were examined by 5 point Likert scale. Findings showed that all facilities of both types of high schools received high ratings in terms of safety, utilization, and technology performance. However, the evaluation index on 'various used outdoor space' and 'public buildings harmonized with surroundings' of the education function of both types of high schools was low, which implies that the facility related to the education function needs to be improved. It infers that facilities are simplified and harmony with surroundings disappears when altering the design of the school building due to the convenience of building and the problem of the budget. Therefore, these need to be primarily controlled. Additionally, in high schools with general facilities, the evaluation index on 'aesthetic interior and exterior design of comfort', 'the responsive space to the demand for teaching and learning of the function of education', and eco-friendless were so low that these factors need to be considered when designing the school building.
