Due to the popularity and advancement of 4G/5G networks, mobile games have already currently become profitable tools for major internet platforms. These games are even refined to cover almost all age groups of the population rather than the young people. Yet in the perception of the public, mobile games have always seemed to be associated with various derogatory terms such as interfering with learning, addiction, and violence. K12 students usually have less self-control capability, and they are undoubtedly the biggest advocates of mobile games. This paper summarizes the technological development of mobile games from the aspects of hardware and software in chronological order. The psychological and social problems that mobile games have brought to K12 students are analyzed from a neutral perspective. At the end of the paper, the future development of educational games and current limitations of mobile games are also given for the explorations of future trends of game-based education. This position paper aims to provide the insight of what psychosocial impacts that the current mobile games have on the student, and it may also serve as a reference for the how the game-based education has been developing according to the mobile technology wise.
With the people’s awareness of the “3Rs” in recent years, using recycled high-density polyethylene (HDPE) and random copolymer polypropylene (PPR) as the base materials for piping fabrication has become a mainstream in scholastic path and industrial engineering. In this study, the modified maleic anhydride-grafted polyethylene (POE-g-MAH) compatibilizer was fabricated to increase the interfacial adhesion and dispersion. With the surface modification of calcium carbonate, a POE-g-MAH/CaCO3/HDPE polymer composite has been prepared. Such modified polymer composites can further reinforce the processing performance and mechanical properties of recycled HDPE and PPR materials. The results indicated that with the introduction of the polymer composite, significant enhancement of the recycled materials in the aspects of processability, tensile strength, flexural performance, and impact force could be obtained, and the POE-g-MAH/CaCO3/HDPE polymer composite would contribute to the impressive balance between high rigidity and toughness. In addition, the feasibility and mechanical properties of the recycled HDPE-PPR-POE-g-MAH/CaCO3/HDPE blended system were also studied: with the help of a composite microcapsule, the gap of mechanical capacity between recycled and non-recycled materials was further reduced, and such a blended system was capable of being commercialized in the piping industry.
The surface of high-pressure crystallized ultra-high molecular weight polyethylene (UHMWPE) was modified for application as an artificial cartilage material. A UHMWPE surface pretreated by a series of processes, including treatment with O2-plasma and ethylenediamine solution, was coated with hyaluronic acid (HA). After that, adipic acid dihydrazide (AAD) was added to partially crosslink the HA coating in order to enhance its durability. The modified samples were verified by water contact angle measurement and Fourier transform infrared spectrometry. Both HA layers, original and crosslinked, were also quantitatively evaluated by carbohydrate chemistry assay according to the absorbance of the incident light. The tribological performance of the samples was evaluated by a pin-on-disk test rig lubricated by normal saline under an average pressure of 18 MPa and at a sliding speed of 0.03 m/s for 45 h. The wear resistance of the HA-coated UHMWPE specimens promoted by the crosslink process was superior to that of the original HA-coated sample, and that resistance was maintained after immersion in saline solution for one month.
