In order to secure pedestrians' right to walk, we have up-cycled second hand mobile phones to overcome limitations of the existing survey methods, analysis methods, and diagnosis to reduce pedestrian traffic accidents. Second hand mobile phones were up-cycled to produce mobile CCTVs and installed in areas where pedestrian deaths rate is high to secure image data sets for the period of more than 24 hours. It was analyzed by applying image visualization technology and clouding reporting technology, and more precise and accurate results were derived through modeling based on artificial intelligence learning and GIS-based diagnostic guidance. As a result, it was possible to analyze the risk factors and number of pedestrian safety, and even factors that were not known in the existing method could be derived. In addition, the traffic accident risk index was derived by converting data into one year to verify whether second hand mobile phone up-cycling mobile CCTV will be an objective tool for finding pedestrian risk factors. Up-cycling mobile CCTV of second hand mobile phones newly applied through research can be used as a new tool to find pedestrian risk factors, and it can be used as a service to protect the safety of the traffic vulnerable other than pedestrians.

The goal of this study was to improve environmental awareness by systematically developing a hands-on online lesson for adults on making drink bags by upcycling discarded umbrella cloth. The lesson was developed using an ADDIE model. During the analysis stage, the instructional design direction was established based on the findings of previous studies. In the design stage, the operation of practical classes in the online environment was specifically planned. The contents of education and the training time were also determined. The materials developed during the development stage included a kit and theoretical information containing images to raise awareness of environmental pollution and the significance of upcycling, as well as videos and photos. During the implementation stage, two sessions were held three months apart. A total of 36 adults participated, with 18 participants in each session. In the evaluation stage, the first session participants provided feedback on class satisfaction, which led to improvements. Positive feedbacks were received from the second session participants, who expressed satisfaction with the smooth communication and easy approaches to the learning materials. In both instances, the surveys on environmental consciousness and attitudes yielded an overall average score of 4.27, indicating a generally positive evaluation.

현재 3D프린터의 원료는 대부분 필라멘트를 사용하고 있는데 가격이 고가인 점과 제작 시간의 문제점으로 3D프린팅 하는데 많은 제약이 따르고 있다. 또한, 원료를 재생 및 재활용하는 3D프린터는 현재까지는 없다. 특히 대형 출력물은 많은 원료가 투입되어야 하기 때문에 제조단가가 상승하고, 그에 따른 3D프린터의 보급과 서비스 확장에도 한계가 있다. 본 연구에서는 현재 재활용되고 있는 플라스틱 소재를 재활용할 수 있는 3D프린터 시스템의 기술개발과 응용서비스를 분석하였다.

The purpose of this study was to propose up-cycling fashion designs, based on guidelines derived from up-cycling fashion brand products and their required elements of the design. The study thus categorized required elements into environment, significance, economy, function, design, and material, then extracted a set of design guidelines. The guidelines for waste resource-based up-cycling fashion design include the followings: First, authenticity, taking mutual environmental relations into account. Second, rarity of products beyond the domain of standardized ready-made goods thanks to manual operation. Third, storytelling, reflecting the consumer history. Fourth, sustainability to signify the circulation of matters. Fifth, experimental characteristic to fulfill creative innovation. Sixth, changeability through interactions with wearers. The investigator decided design concepts based on them and created up-cycling design works with waste plastic bags, shirts, stockings, neckties, outdoor mats, and backpacks in a variety of formative expressive techniques.

A feasibility test was carried out for upcycling of waste jelly-filled communication cables together with the development of environmentally friendly processes and equipments. High pressure water injection is proved to be an exceptionally environmentally friendly and highly efficient mechanical process. A batch-type cable barking equipment is designed and built on the basis of computational fluid dynamics modelling. It is optimized in terms of energy consumption and productivity with very high copper recovery of 99.5%. Copper nano-powder is prepared by an electrical wire explosion in ethanol media in order to improve the value of final products, and the preliminary economical assessment is also conducted.
