Owing to the increasing demand for electric vehicles (EVs), appropriate management of their waste batteries is required urgently for scrapped vehicles or for addressing battery aging. With respect to technological developments, data-driven diagnosis of waste EV batteries and management technologies have drawn increasing attention. Moreover, robot-based automatic dismantling technologies, which are seemingly interesting, require industrial verifications and linkages with future battery-related database systems. Among these, it is critical to develop and disseminate various advanced battery diagnosis and assessment techniques to improve the efficiency and safety/environment of the recirculation of waste batteries. Incorporation of lithium-related chemical substances in the public pollutant release and transfer register (PRTR) database as well as in-depth risk assessment of gas emissions in waste EV battery combustion and their relevant fire safety are some of the necessary steps. Further research and development thus are needed for optimizing the lifecycle management of waste batteries from various aspects related to data-based diagnosis/classification/disassembly processes as well as reuse/recycling and final disposal. The idea here is that the data should contribute to clean design and manufacturing to reduce the environmental burden and facilitate reuse/recycling in future production of EV batteries. Such optimization should also consider the future technological and market trends.

There have been diverse discourses arguing that new design has been emerging in the 21 st century. However, there have been very few trials to identify systematically the characteristics_of new design paradigm and to develop new design educational program based on them. Thus, this paper aims at development of strategy of new design educational program according to the characteristics of new design paradigm. At first, design is viewed as part of 'culture'and the structure of culture is identified: 'Artifact', 'Value', and 'Basic Assumptions'. Similarly, design is found to comprise of three fundamental attributes: 'Function', 'Aesthetics','Symbolic'. These levels are shown to be in the relation of mutually recycling influences. These structural framework is used to understand the design methods and qualification of designers over the development of design paradigms: vernacular design, machine age, and information-knowledge age. The result leads the list of requirements of new educational design program: 'Human-Centered','Situation-Based','User-Participatory', and 'Intangible'. The model of strategy of new educational design program is developed and proposed.

This study purports to investigate the status quo of the environmentally-friendly green healthcare in teaching hospitals through the questionnaire survey. Data were collected from a total of 46 hospitals. The survey results revealed that most teaching hospitals did not meet the global standard of environmentally-friendly green hospitals. Especially, such items as alternative energy system, water recycling, CO2 emission reduction, green building construction, installation of pond or spring were found to be significantly below global standard. Based upon the study results, various strategies for establishing green hospitals were discussed. For example, energy saving design, such as solar heating, natural wind cooling, automatic temperature controller, green material use, wall surrounded by ivy, were recommended. In conclusion, the strategy and evaluation tool developed in the study will provide a good guide for establishing environmentally-friendly green hospitals.

For improving high-safety, convenience, and ride comfort, the automotive design suffers from radical increase of the weight, the recycling-related rules, regulations on the waste gas, and environmental protection of the resources. Among them, it is well known that the weight increase is the most critical. Thus, in order to minimize the weight of the body-in-white that takes up 20-30% of the whole weight of the automobile, most automotive manufacturers have attempted to develop the aluminum intensive body-in-white using aluminum space frames. In this research, the crush test and simulation for aluminum extrusions are performed to evaluate the collapse characteristics of that light weighted material. Also. the same test and simulation was done for aluminum extrusions filled with structural foam. Then, these results are analyzed and compared. From these studies, the effectiveness of structural foam is evaluated in improving automotive crashworthiness. Finally, the design strategy and guideline of the structural form are suggested in order to improve the crashworthiness for aluminum space frame in the vehicle.

This study was conducted to characterize food waste leachate (FWL) and to compare its characteristics according to generation source: feed supplement- and compost-producing facilities. FWL contained high levels of organic compounds such as carbohydrate, protein and lipid. The moisture content of FWL was among the range of conventional wet anaerobic digestion. FWL was acidic (pH of $4.0{\pm}0.3$) and showed high coefficients of variance for specific parameters: carbohydrate, protein, lipid, ethanol, acetic acid and propionic acid. FWL derived from feed supplement-producing facilities showed slightly lower concentrations of most parameters than FWL derived from compost-producers. However, the difference was not significant at 5% significance level according to analysis of variance.
