This study addresses the development of a new educational direction for Korean language education in the post-human era, namely, the development of multiliteracies education. As the world is now enveloped in COVID-19, all fields are seeking new breakthroughs, and education in particular is the first to adapt to the post-epidemic era. This prepares new types of human resources for the post-human era, and actively responds to new concepts such as environmental mutations and the AI era at a later stage. Based on the above, this study takes Korean language education as an example of a humanities subject, and discusses how it can find its own new point of development and adapt to its surroundings in a way that provides a new concept of education. The study of multiliteracies in Korean language education has evolved in recent years, largely due to the development of science, technology and multimedia. This external environment has necessitated changes in traditional language education and has urged educators to reconsider educational goals such as the overall literacy of students. The New London Group, the first to propose multiliteracies, redefined the concept in 2013 and added elements of social activism and ethics in the virtual society to it. These two concepts are, of course, at the forefront of the future development of multiliteracies education in Korean language education, which is to prepare students to think about harmonious relationships with non-humans and nature based on a human-centred approach, and to articulate new ethical and moral concepts within the social framework of the virtual space. In line with this educational objective, researchers should take into account the diversity of today’s Korean language learners, the diverse requirements of the learners’ learning purposes, and the specialised and complex dimensions of teaching content. Furthermore, in terms of changing ethical and moral concepts within the virtual space, researchers should focus on developing learners’ ability to identify social issues through the media and how to deal with these social issues in concrete behavioural terms.

Research On Solutions To Slicing Errors In FDM 3D Printing Of Thin-walled Structures

QINGYUAN ZHANG,이병춘 한국인터넷방송통신학회 2024 International Journal of Internet, Broadcasting an Vol.16 No.1

The desktop-level 3D printing machines makes it easier for independent designers to produce collectible models. Desktop 3D printers that use FDM (Fused Deposition Modeling) technology usually use a minimum nozzle diameter of 0.4mm. When using FDM printers to make Gunpla models, Thin slice structures are prone to slicing errors, which lead to deformation of printed objects and reduction in structural strength. This paper aims to analyze the printing model that produces errors, control a single variable among the three variables of slice layer height, slice wall thickness and filament type for comparative testing, and find a way to avoid gaps. To provide assistance for using FDM printers to build models containing thin-walled structures.

A new linear heptafluoro glycidyl ether binder: synthesis, characterization, and mechanical properties

Qingyuan Zhang,Junjie Chen,Bo Jin,Rufang Peng 한국고분자학회 2023 Macromolecular Research Vol.31 No.7

Fluorinated binders have currently received extensive attention in the research of binders due to their unique chemical properties. In this study, poly 2-(2,2,3,3,4,4,4-heptafluorobutoxymethyl) oxirane, i.e., poly(HFEE) was synthesized by a one-step substitution and cationic ring-opening polymerization using epichlorohydrin and 2,2,3,3,4,4,4-heptafluoro-1-butanol as raw materials. The corresponding characterization, such as FT-IR and NMR, of HFEE confirmed its successful synthesis. The differential scanning calorimetry (DSC) test shows that poly(HFEE) had a low glass transition temperature (Tg) of − 64.7 °C, indicating that it developed the better stability performance. At the same time, the thermal and mechanical properties of HFEE cured by polymethylene polyphenyl polyisocyanate (PAPI) were studied. The effects of curing temperature and PAPI content were investigated, and the corresponding rules were summarized. Thermogravimetric analysis (TGA-DTG) was utilized to evaluate the thermal stability of poly(HFEE) and the result showed that the sharp weight loss was at the temperature of 377 °C. This new strategy is devised for the utility of poly(HFEE) enabling it extension to be potential fluorinated binder for solid propellants.

Through this research, it is intended to improve the critical media literacy of the Chinese by designing this educational scheme. In recent years, research on improving the media literacy of Chinese people has become increasingly important in response to the low media quality of Chinese people. To this end, firstly in this study the concept and extension of media literacy are examined, and secondly the relationship between media literacy and critical thinking is examined, based on that the concept of critical media literacy is redefined. At the same time, the new forms of literary works in the media age are identified. Using this as a contact, the two concepts of media literature and critical thinking have been re-linked. Through the discussion of the above concepts and relationships, the educational principles of critical media literacy are reorganized. To be more specifically, in this study, it is focused on the various media forms of Yoon Dong-Ju’s poetry and a educational scheme is designed aiming at improving Chinese media literacy. In this scheme the understanding process and appearance of Chinese learners are investigated. And hopefully through this scheme to grasp the process of Chinese learners’ understanding of diversified media texts and critical understanding of these media texts. Finally, through the above investigation, a critical media literacy teaching program suitable for Chinese people was designed. I hope this study can be used as a reference basis for future media literacy research, and also a new perspective and a way of thinking for Chinese students is provided by using Korean literary works as a medium. And it facilities the students to re-examine their media literacy, critically understand various media texts, and make their own critical value judgments in line with social values and ethical attitude.

Simulation study on CFRP strengthened reinforced concrete beam under four-point bending

Dongliang Zhang,Qingyuan Wang,Jiangfeng Dong 사단법인 한국계산역학회 2016 Computers and Concrete, An International Journal Vol.17 No.3

This paper presents numerical modeling of the structural behavior of CFRP (carbon fiber reinforced polymer) strengthened RC (reinforced concrete) beams under four-point bending. Simulation of debonding at the CFRP-concrete interface was focused, as it is the main failure mode of CFRP strengthened RC beams. Here, cohesive layer was employed to model the onset of debonding, which further helps to describe the post debonding behavior of the CFRP strengthened RC beam. In addition, the XFEM approach was applied to investigate the effects of crack localization on strain field on CFRP sheet and rebar. The strains obtained from the XFEM correlate better to the test results than that from CDP (concrete damaged plasticity) model. However, there is a large discrepancy between the experimental and simulated loaddisplacement relationships, which is due to the simplification of concrete constitutive law.

Investigating Various Factors Affecting the Long-Term Compressive Strength of Heat-Cured Fly Ash Geopolymer Concrete and the Use of Orthogonal Experimental Design Method

Hongen Zhang,Lang Li,Prabir Kumar Sarker,Tao Long,Xiaoshuang Shi,Qingyuan Wang,Gaochuang Cai 한국콘크리트학회 2020 International Journal of Concrete Structures and M Vol.14 No.1

This work quantified the hierarchy of the influence of three common mixture design parameters on the compressive strength and the rate of strength increase over the long term of low-calcium fly ash geopolymer concrete (FAGC) through designing 16 mixtures by the orthogonal experimental design (OED) method. The parameters used in the study were liquid to fly ash (L/FA) ratio, sodium hydroxide concentration (SHC) and sodium silicate solution to sodium hydroxide solution (SS/SH) ratio. The L/FA ratio showed little effect on compressive strength when it was varied from 0.40 to 0.52. SHC showed the greatest influence on compressive strength with little impact on the rate of strength increase after the initial heat curing. Even though the SS/SH ratio showed a small effect on the initial compressive strength, it had a considerable influence on the rate of strength increase over the long term. It was found that the compressive strength at 480 days was positively related to the Na₂O/SiO₂ molar ratio when it was varied from 0.49 to 0.80 and the Si/Al molar ratio was increased up to 1.87. Analysis of the failure types of specimens demonstrated that compressive strength of FAGC was associated with the strength of the mortar–aggregate interface zone (MAIZ).

Yue Li,Jing-Ying Zhang,Xin-Yue Zhao,Li-Ya Pan,De-Hao Jin,He-Xing Xu,Hu-Zhe Cui,Yan-Qun Liu,Xiang-Zheng Qin,Qingyuan Li 대한정형외과학회 2021 Clinics in Orthopedic Surgery Vol.13 No.2

Background: The accessory tendon of the extensor hallucis longus (ATEHL) muscle is a common abnormal structure, and its clinical significance remains debatable. In this study, we provide the incidence of the ATEHL and characterize its morphological types in Asian cadavers and investigate its clinical applications. Methods: The tendons from 50 adult cadaveric feet, fixed in 10% formalin, were analyzed. We measured the length and width of both the ATEHL and the extensor hallucis brevis (EHB). Results: All dissected specimens had an ATEHL. The first metatarsophalangeal joint was surrounded by an accessory tendon that inserted onto the joint capsule and the dorsal base of the proximal phalanx. We classified the ATEHL into 3 types based on their directions. Differences in ATEHL type based on sex were not statistically significant. Conclusions: We found an ATEHL in all cadaveric specimens in this study. We surmise that the ATEHL acts as an antagonist with the EHB when the toe is extending, which might help prevent the occurrence of hallux valgus deformity.
