In this study, graphene layer was grown on metal microwire using chemical vapor deposition. The difference of carbon solubility between copper and nickel resulted in the formation of mono-layer and multi-layer graphene were formed on the surfaces of copper and nickel microwires, respectively. During the growth of graphene at high temperature, copper and nickel were recrytallized and the grain size increased. The ampacity of graphene/copper microwire was improved by approximately 27%, 1.91×105 A/㎠, compared to pristine copper microwire. Similar to this behavior, the ampacity of multilayer graphene/nickel microwire was 4.41×104 A/㎠ which is about about 36% improved compared to the pure nickel microwire. The excellent electrical properties of graphene/metal composites are beneficial for supplying the electrical energy to the high-power electronic devices and equipment.

This paper criticized that online classes during the Covid-19 period were centered on knowledge and information education, and sought ways to improve empathy as a way to improve students' sociality. The teaching-learning process was designed around the movie <(500) Days of Summer> which has the theme and story of parting and growth. On this paper the stage of empathy was divided into three stages, recognize-into, feeling-into, emotional-transaction stage. In particular, considering the process of transitioning from emotional empathy to behavioral empathy as the key to communication education, the class was designed in five stages, with an expression stage between the feeling-into stage and the emotional-transaction stage. This course is possible when learners sympathize with the work itself and reflect on their own narrative, so literary therapeutic was used, and students's response statements were collected to prove that this process is meaningful for improving empathy. In this article, the class was designed for the movie <(500) Days of Summer>, but this teaching-learning model can be applied to other contemporary film texts.

Recently, research attention has been focused on vibration-free vehicles to transport small numbers of expensive electronic products. Vibration-free vehicles can be used to transport expensive test equipment or semiconductors, mainly produced in the domestic IT industry, and can serve as a readily available transportation system for short driving distances due to the increased efficiency on narrow national highways. This study was aimed at developing a Z-Spring to minimize the vibration by installing an air spring instead of the plate spring applied to conventional freight cars and to prevent the damage of the loaded cargo from the shock occurring during movement. The mechanical properties (elastic modulus, tensile strength, and shear strength) of carbon fiber (CF) and glass fiber (GF) prepreg were derived, and ANSYS ACP PrepPost analyses were performed. It was observed that in the case of hybrid composites, the total deformation and equivalent stress are higher than that of CFRP; however, in terms of the unit cost, the hybrid Z-Spring is more inexpensive and durable compared to the GF.

This study was conducted to suggest the Cudrania tricuspidata leaf and Achyranthes japonica Nakai Complex (CAC) possibility of use as a functional natural material for improving bone disease. Cudrania tricuspidata leaf and Achyranthes japonica Nakai were mixed in the same amount, extracted with hot water, and then powdered and used in the study. After, the cytotoxicity of CAC for osteoblasts (MG63 cell), osteoclasts (differentiated RAW264.7 cell), and macrophages (RAW264.7 cell) were evaluated by MTT assay, and ALP assay and TRAP assay were performed to confirm the differentiation capacity of osteoblasts and osteoclasts, respectively. In addition, the anti-inflammatory effect in macrophages was evaluated by ELISA, qRT-PCR, and western blot assay. CAC did not proliferated osteoblasts and osteoclasts, but increased ALP activity against osteoblasts differentiation and decreased TRAP activity against osteoclasts differentiation. CAC did not proliferated macrophages but decreased nitric oxide production. Also, decreased NOS2, IL1B, IL6, PTGS2, and TNFA gene expression, and JNK and p38 protein phosphorylation in a concentration-dependent manner, but ERK protein phosphorylation was not changed. As a result, CAC increased the differentiation and activation of osteoblasts, inhibited the differentiation and activation of osteoclasts, and regulated the expression of inflammatory cytokines in macrophages. Therefore, it is thought that CAC can be used as a functional natural material that prevents bone disease and has an anti-inflammatory effect.

The purpose of this study was to identify factors influencing the clinical decision making ability of nurses in long-term care hospitals. Data were collected from 174 nurses working in long-term care hospitals in G-do from October 11 to December 10, 2021. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation and stepwise multiple regression through the SPSS 23.0. As a result of the study, the clinical decision making ability was positively correlated with critical thinking disposition(r=.494, p<.001) and nursing work environment(r=.451, p<.001). Critical thinking disposition and nursing work environment explained 33.1% of clinical decision making ability. In order to improve the clinical decision making ability, which is the core competency of nurses, education to increase critical thinking disposition and the creation of a desirable nursing work environment are necessary. In future research, research to identify various variables affecting the clinical decision making ability of nursing hospital nurses, and research for the development and effectiveness of programs to improve clinical decision making ability are suggested.
