        This study aims to use Art brut works—the artwork of the socially underprivileged and alienated—to influence social roles in fashion design, employing a formative expression method to promote social acceptance of diversity in the industry. The research method involved investigating Art brut’s concept and evolution in domestic and foreign literature and previous studies. The formative characteristics of the movement were derived by analyzing the works of Art brut artist Johann Hauser. One hundred and twenty images of Johann’s work were collected through online sources like the Gugging Museum’s website, Christian Berst Gallery’s website were developed as fashion design using the CLO 3D program. The formative characteristics of Johann’s works appeared to be transparent overlapping, divisional decorativeness emphasized simplicity, and vibrant chromaticity. Based on this analysis, the results of the 3D digital fashion designs were as follows. First, the characteristics of the atypical objects and figures in Johann’s works were applied to the design silhouette, revealing a uniquely beautiful form. Second, Johann used a method in which numerous line shapes overlap and fill the area. The point of connecting the work is expressed as a graphic pattern by decorating the lines of the hem and hem of the garment with piping or attaching overlapping straps on top of pants and dresses. Third, the combination of overlapping colors used in Johann’s work is a color block design of fashion, which utilizes the formative fun.

        Devices with negative differential transconductance (NDT) and negative differential resistance (NDR) have shown a strong potential for digital electronics with high information density due to their N-shaped current–voltage (I–V) characteristics leading to multiple threshold voltages ( Vths). The 2D materials, such as graphene, hBN, MoS2, WS2, etc., offer an attractive platform to achieve NDT and NDR because of the absence of dangling bonds on the surface, leading to a high-quality interface between the layers. The 2D materials' unique property of the weak van der Waals (vdW) interactions without dangling bonds on the heterostructure devices shows the way for the applications more than-Moore devices. This review holds a well-timed overview of 2D materials-based devices to develop future multi-valued logic (MVL) circuits exhibiting high information density. Notably, the recent advances in emerging 2D materials are reviewed to support the directions for future research on MVL applications.

        This study aims to analyze research trends regarding outdoor wear. For this purpose, the data-collection period was limited to January 2002–October 2022, and the collection consisted of titles of papers, academic names, abstracts, and publication years from the Research Information Sharing Service (RISS). Frequency analysis was conducted on 227 papers in total to check academic journals and annual trends, and LDA topic-modeling analysis was conducted using 20,964 tokens. Data pre-processing was performed prior to topic-modeling analysis; after that, topic-modeling analysis, core topic derivation, and visualization were performed using a Python algorithm. A total of eight topics were obtained from the comprehensive analysis: experiential marketing and lifestyle, property and evaluation of outdoor wear, design and patterns of outdoor wear, outdoor-wear purchase behavior, color, designs and materials of outdoor wear, promotional strategies for outdoor wear, purchase intention and satisfaction depending on the brand image of outdoor wear, differences in outdoor wear preferences by consumer group. The results of topic-modeling analysis revealed that the topic, which includes a study on the design and material of outdoor wear and the pattern of jackets related to the overall shape, was the highest at 30.9% of the total topics. The next highest topic was also the design and color of outdoor wear, indicating that design-related research was the main research topic in outdoor wear research. It is hoped that analyzing outdoor wear research will help comprehend the research conducted thus far and reveal future directions.

        In order to humanize and contextualize ESL/EFL learning, poetry writing has been suggested and considered as an effective strategy for meaningful literacy. However, there is a lack of empirical evidence for the pedagogical significance of poetry writing on language learning. To make up for the dearth of research about poetry writing, the present study explored to what extent a primary English language learner can express herself through poetry writing in an American classroom and the significance of poetry writing as meaningful literacy in ESL/EFL learning. Adopting a qualitative research approach, this small-scale case study conducted textual analyses of a young English language learner’s poetry works and in-depth interviews with her. Findings suggest that poetry writing encouraged the participant learner to express herself with her own voice, enhanced her L2 linguistic awareness, provided meaningful learning opportunities―authorship and readership―, and motivated the learner to overcome challenges as an English language learner. The present study contributes to the understanding of young English language learners’ poetry writing in the field.

        We investigate the astronomical phenomenon records of Sukjong’s 𝐶ℎ𝑢𝑛𝑏𝑎𝑛𝑔-𝐼𝑙𝑔𝑖 made by 𝑆𝑖𝑔𝑎𝑛𝑔𝑤𝑜𝑛 (Royal Educational Office of the Crown Prince) at which King Sukjong was the crown prince (i.e., 1667 January 24–1674 September 22). From the daily records of 2,799 days, we extract the astronomical records of 1,443 days and classify them into 14 categories. Then, we group the records of each category into five phenomena (Atmosphere, Eclipse, Daylight Appearance, Apparition, and Appulse) and compare them with the results of modern astronomical computations wherever possible. Except for Atmosphere group comprising records of meteorological events, such as solar halo, lunar halo, and unusual clouds, the significant findings in every other group are as follows: In Eclipse group, the solar eclipse that occurred on 1673 August 12 was unobservable in Korea, which is in contrast to the record of 𝐽𝑜𝑠𝑒𝑜𝑛𝑤𝑎𝑛𝑔 𝑗𝑜-𝑆𝑖𝑙𝑙𝑜𝑘 (Annals of the Joseon Dynasty), which states that the sun was in eclipse around sunset time, as observed at 𝑁𝑎𝑚 mountain. From the lunar eclipse records, we verify that the Joseon court did not change the date of the events observed after midnight. In Daylight Appearance group, we confirm that this phenomenon was observed during the daytime and not during twilight. We further suggest that if observation conditions are met, a celestial body brighter than −2.3 mag could be seen during the daytime with the naked-eye. In Apparition group, we find the possibilities that the Orionid meteor shower had influence on the meteor records and the seasonality on the aurora records. We also find that the Korean records in which the coma of comet C/1668 E1 was located below the horizon were overlooked in previous studies. Finally, we find that the records of Appulse group generally agree with the results of modern calculations. The records of 𝐵𝑒𝑜𝑚 (trespass in literal) and 𝑆𝑖𝑘 (eating in literal) events show average angular separations of 1.2◦ and 1.0◦, respectively. In conclusion, we believe this work helps study the astronomical records of other logs of 𝑆𝑖𝑔𝑎𝑛𝑔𝑤𝑜𝑛, such as Sunjong’s 𝐶ℎ𝑢𝑛𝑏𝑎𝑛𝑔-𝐼𝑙𝑔𝑖.

        We investigate the diffusion process of Thomson-scattered line photons in both real space and frequency space through a Monte Carlo approach. The emission source is assumed to be monochromatic and point-like embedded at the center of a free electron region in the form of a sphere and a slab. In the case of a spherical region, the line profiles emergent at a location of Thomson optical depth τTh from the source exhibit the full width of the half maximum σλ ≃ τ 1.5 Th . In the slab case, we focus on the polarization behavior where the polarization direction flips from the normal direction of the slab to the parallel as the slab optical depth τTh increases from τTh ≪ 1 to τTh ≫ 1. We propose that the polarization flip to the parallel direction to the slab surface in optically thick slabs is attributed to the robustness of the Stokes parameter Q along the vertical axis with respect to the observer’s line of sight whereas randomization dominates the remaining region as τTh increases. A brief discussion on the importance of our study is presented.

        Undenatured castor oil and trimethylolpropane (TMP) were used to obtain bio-based water-based polyurethane. Isophorone diisocyanate (IPDI) was incorporated into the formulation to obtain a transparent film, and ethylenediamine (EDA) was used for chain extension. In order to measure the change in physical properties according to the contents of castor oil and TMP, each tensile strength, elongation, and abrasion resistance test was conducted. As the contents of castor oil and TMP increased, the tensile strength increased, the elongation decreased, and the surface hardened strongly as the respective contents increased.

        Given the domestic situation, all nuclear power plants are located at the seaside, where interim storage sites are also likely to be located and maritime transportation is considered inevitable. Currently, Korea does not have an independently developed maritime transportation risk assessment code, and no research has been conducted to evaluate the release rate of radioactive waste from a submerged transportation cask in the sea. Therefore, secure technology is necessary to assess the impact of immersion accidents and establish a regulatory framework to assess, mitigate, and prevent maritime transportation accidents causing serious radiological consequences. The flow rate through a gap in a containment boundary should be calculated to determine the accurate release rate of radionuclides. The fluid flow through the micro-scale gap can be evaluated by combining the flow inside and outside the transportation cask. In this study, detailed computational fluid dynamic and simplified models are constructed to evaluate the internal flow in a transportation cask and to capture the flow and heat transfer around the transportation cask in the sea, respectively. In the future, fluid flow through the gap will be evaluated by coupling the models developed in this study.

        South Korea has a temperate climate with four distinct seasons. However, summers are extremely hot and humid, which negatively affects industrial animal production. Hanwoo are native cattle that have traditionally been raised in the natural environment of Korea. The present study investigated the effects of birth and lactation season on the birth and weaning weights of Hanwoo calves. Data were collected from 100 local breeding farms between 2016 and 2021. A total of 56,970 (males, 29,530; females, 27,440) Hanwoo calves were classified according to sex or birth and weaning season (March–May, spring; June–August, summer; September– November, fall; and December–February, winter). The birth weight of Hanwoo calves differed according to the birth season. As such, birth weight of the summer-born calves was the lowest. Additionally, the 90-day weaning weight was positively correlated with birth weight. Interestingly, however, the 90-day weaning weight was not related to the birth season but was related to the 2-month seasonal effect during the lactation period. Furthermore, the 90-day weaning weight was the lowest during the summer lactation period. In the beef cattle industry, daily weight gain is an important economic characteristic related to feed efficiency and growth. Our findings will contribute the management of Hanwoo cattle and analysis of changes in economic characteristics due to high temperatures.

        Current studies have revealed the capacity of mesenchymal stem cells (MSCs) in term of immunomodulatory properties, and this distinct potential is downgraded according to the disease duration of patients-derived MSCs. In order to enhance the immunomodulatory and anti-tumorigenic properties of the rheumatoid arthritis (RA) joints-derived MSCs, we aggregate synovial fluid-derived MSCs from RA joints (RA-hMSCs) into 3D-spheroids by the use of hanging drop culture method. Cells were isolated from synovial fluids of RA joints with longstanding active status over 13 years. For aggregation of RA-hMSCs into 3D-spheroids, cells were plated in hanging drops in 30 μL of advanced DMEM (ADMEM) containing 25,000-30,000 cells/ drop and cultured for 48 h. To analyze the comparative immunomodulatory effects of 3D-spheroid and 2D monolayer cultured RA-hMSCs and then cells were cultured in ADMEM supplemented with 20% of synovial fluids of RA patients for 48 h and were evaluated by qRT-PCR for their expression of mRNA levels of inflammatory and antiinflammatory markers. Cellular aggregation of RA-hMSCs was observed and cells were aggregate into a single sphere. Following treatment of RA patient’s synovial fluids into the RA-hMSCs, spheroids formed RA-hMSCs showed significantly (p < 0.05) higher expression of TNFα stimulated gene/protein 6 (TSG-6) than the monolayer cultured RAhMSCs. Therefore, the 3D-spheroid culture methods of RA-hMSCs were more effective than 2D monolayer cultures in suppressing inflammatory response treated with 20% of RA-synovial fluids by expression of TNFα (TSG-6) according to the immune response and enhanced secretion of inflammatory factors.

        This study aimed to determine if animal-assisted therapy could enhance language and social interactions in autistic children. It is a single case study of a 6.7-year-old child diagnosed with second-rate autism disorder with a program of twelve sessions in total, a session per week, and fifty minutes per session. The program was constructed to increase the frequency of using words and to improve interpersonal relationships through contact with peers or strangers. To do this, SCAR and E-CLAC scales went through a pretest and posttest and the changes in main behaviors observed during the twelves sessions were analyzed, obtaining the following results: First, the animal-assisted therapy program allowed the autistic child to use daily words about twice more frequently than usual. Second, the animal-assisted therapy program was effective in allowing the autistic child to improve social interactions with peers or strangers around the dog. Therefore, the animal-assisted therapy program was effective in helping the autistic child enhance language and social interactions.

        Wild birds, especially aquatic birds, are the natural reservoir of avian influenza virus (AIV), and many kinds of water body can be contaminated with feces of these birds. Seasonally, AIVs can be dissolved in the environmental water from the feces of the infected birds, and this water can be a target for viral detection and identification. In this study, we employed and tested three different filters for concentrating AIV, and it was shown that high concentration factor in terms of viral density could be achieved with viral samples diluted with natural water. Wild bird fecal samples containing low pathogenicity H5 AIVs were successfully concentrated with the adsorption and elution method using mixed cellulose esters membrane; the recovery rate of virus was 35.5 % and the concentration factor was about 50 on average. For the larger volume of water sample, we proved that an inline disposable filter with high surface area, 300 cm2, has a comparable concentration factor to the adsorption and elution method and the filter could be used in the field conveniently by being plugged into peristaltic pump. These validated methods for water sampling may be used as a supplementary for virological surveillance on wild migratory birds or during the epidemiological investigation on the environment near affected premises by AIV.

        Influenza A viruses (IAVs) are members of the family Orthomyxoviridae and genus Orthomyxovirus. Avian and mammalian species are the host of IAVs, which includes humans and dogs. Canine influenza virus (CIV) is an emerging pathogen that causes severe and acute respiratory diseases in dogs. This study monitored the antigen and antibody against CIV in dogs in the Republic of Korea (ROK) from 2016 to 2021. One thousand and seventy-two nasal swabs and 1,545 blood samples were collected from animal hospitals and animal shelters. Five nasal swabs in 2017 and seven in 2018 from stray dogs were positive for CIV according to RT-PCR. The prevalence of H3N2 CIV ranged from 9.5% to 24.8%, according to the hemagglutination inhibition (HI) assay. On the other hand, none of the serum samples from 2018 to 2021 showed seropositivity against the avian H5, H7, and H9 viruses. The HI titers for H3N2 ranged from 16 to 512. The distribution of HI titer 16–32 was 57.6% in seropositive samples. The pet dogs were vaccinated against CIV, but the stray and military dogs were unvaccinated. In 2017 and 2018, the seroprevalence of CIV in stray dogs was higher than in the other years, and viral RNA was detected in nasal swabs. It may mean previous exposure of stray dogs to CIV. With the increasing number of pet dogs and the close contact between humans and dogs, canines could serve as an intermediate host for transmitting IAVs to humans. Therefore, continuous surveillance of CIV is needed for public health and the potential emergence of novel zoonotic viruses.

        This study aimed to examine the cause and consequence of emotional labor strategies based on the emotional labor framework. To investigate the boundary condition of the current research model, the study proposed that job autonomy would moderate the effects of emotional labor on employees' well-being. To achieve the purpose of the study, it was first tested whether neuroticism and extroversion of employees predicted the focal outcomes (i.e., burnout and work engagement) via distinct emotional labor strategies. Second, the moderation effects of job autonomy were tested for each emotional labor strategy in predicting the focal outcomes. Third, the conditional indirect effects of job autonomy on the mediation process were examined. The results revealed that surface acting partially mediated the relationship between neuroticism and burnout, whereas deep acting fully mediated the relationship between extraversion and work engagement. Regarding the moderating effects of job autonomy, it significantly moderated the relationship between surface acting and burnout and between deep acting and work engagement. In addition, from the moderated mediation effects, the conditional indirect effects of job autonomy were significant. Finally, theoretical and practical implications are discussed and limitations and future research directions were suggested.
