The outbreak of Covid-19 has forced teachers of special education in Saudi Arabia to keep to themselves to live in a technology-infused society throughout the virtual teaching and learning process. This study set out to explore the competence, self-efficacy, and autonomy in using information communication technology (ICT) of special education teachers in Saudi Arabia. A total of 244 special education teachers in Saudi Arabia participated in this study. This study adopted the New General Self-Efficacy Scale developed and validated by Chen, Gully, and Eden (2001), as well as the Basic Psychological Needs in Exercise Scale (BPNES) developed and validated by Vlachopoulos and Michailidou (2006). Confirmatory factor analysis (CFA) and multivariate analysis of variance (MANOVA) were used as the main data analysis in this study. The findings showed that special education teachers in Saudi Arabia possessed competence, self-efficacy, and autonomy in using ICT in their teaching and learning process. All the factor loadings in each factor were.75 or higher, indicating good factor loadings. The results of the MANOVA indicated that special education teachers in Saudi Arabia do not report different perceptions of their competence, self-efficacy, and autonomy despite their different gender, age group, academic background, and teaching experiences.

The Metaverse's virtual world is used in various industries and is expected to continue to grow in the future. In addition, the Metaverse is a new type of society that integrates various new technologies, and NFT products play an essential role. Therefore, NFT product characteristics and industry trends should be assessed to revitalize the NFT market. To this end, this study confirms the influence relationship between social presence and NFT product characteristics in the Metaverse environment and examines the impact of each characteristic on consumer satisfaction and continued engagement intention to NFT product. Statistical analysis such as exploratory factor analysis, reliability analysis, confirmatory factor analysis, correlation analysis, and structural equation modeling (SEM) using IBM SPSS Amos was conducted on data collected through a survey targeting male and female Korean consumers in their age group 10 to 50. Study results indicate that social presence significantly impacted all characteristics of NFT products (authenticity, scarcity, rarity, collectability, and interactivity). Scarcity and authenticity significantly impacted consumer satisfaction, and both authenticity and consumer satisfaction significantly impacted continued engagement intention. Thus, effective product development and marketing strategies can be established only by presenting different emphasized characteristics depending on the type of NFT product and the Metaverse's social presence.

Loading time and loading environment of the Dokdo seamounts were studied from flexure model and VGP(Virtual Geomagnetic Pole) determined by gravity and magnetic data. In spite of their similarity in size. a large difference about 50 mGal between gravity anomaly peaks of Dokdo and the Isabu Tablemount suggests different compensation degrees. Flexural modeling results show that the flexural rigidity(effective elastic thickness) of lithosphere for Dokdo is stronger(thicker) than that for the Isabu Tablemount. Also, it implies that the age of lithosphere at the time of loading of the Isabu Tablemount may be younger than that of Dokdo. Magnetic anomalies occur complicated over the Dokdo seamounts. Paleomagnetism was studied from VGP estimated by the least square and the seminorm magnetization methods with 1500 m upward continued magnetic anomalies. Age dating of Dokdo from previous study, flexural modeling, VGP, and geomagnetic polarity time scale suggest that after the cease of spreading in the Ulleung Basin, the Isabu Tablemount was formed first in normal polarity interval and followed by Dokdo. Also, they indicate that the fist large eruption of Dokdo was in normal polarity interval and the second large eruption in reversed polarity interval. The Simheungtaek Tablemount was formed in normal polarity interval between the formations of the Isabu Tablemount and Dokdo. These loading times for the Dokdo seamounts show a good coherence with the compressive stress period after the end of the opening of the East Sea. The Dokdo seamounts probably was caused by volcanism associated with the compressive stress.

Purpose: Most of studies dealing with abfractions are limited to the buccal surfaces of the teeth. In this study, we analyzed the cause for abfraction by investigating the incidence of palatal side abfractions in maxillary posterior teeth. Materials and Methods: We investigated a total of 3193 maxillary posterior teeth by an intraoral examination, model observation, and observation of virtual model fabricated using model scanning. We recorded the results and classified them depending on the type of teeth, age, gender, and side of arches. We also performed Chi-square test to evaluate the statistical significance among the groups (α = 0.05). Results: The incidence of palatal side abfraction of the maxillary molars (10.8%) was higher than the premolars (6.8%), and among them, the incidence of the 1st molars (39.1%) were the highest. The incidence of palatal side abfraction increased with age and was statistically significant (P < 0.05). There was no statistical significance in the difference by gender (P > 0.05); in the case of arches, left arch showed higher incidence and it was statistically significant (P < 0.05). Conclusion: Palatal side abfraction in maxillary posterior teeth was frequently observed in the maxillary 1st molars, and the incidence increased with age. This result suggests that the main reason for abfraction is due to occlusal force.

Objectives: To measure the quality of life in patients according to virtual cerebral palsy severity by using the Korean version of EQ-5D-Y proxy, Visual Analogue Scale (VAS), and Time Trade-Off method (TTO). Methods: The study was conducted in parents of children and adolescents aged 4 to 15 years in Seoul. We analyzed the difference in the utility value according to five levels of cerebral palsy severity in the Gross Motor Function Classification System (GMFCS) and test-retest reliability. Results: 1. There were significant differences in VAS, TTO, and EQ-5D-Y proxy according to the cerebral palsy severity (p<.001). 2. VAS was significantly different according to the respondent's visit to the medical institution, the presence of disease in the respondent, a visit to the child's medical institution, the age of the child, and the sex of the child. The value of TTO was significantly different according to the respondent's visit to the medical institution, respondent's sex, and the age of the child. Also, EQ-5D-Y proxy was significantly different according to the age of the child. 3. Intraclass correlation coefficient values were more than 0.6 for both VAS and TTO at all stages. But for the EQ-5D-Y proxy, the value was less than 0.6 at all stages. Conclusions: The quality of life assessment using EQ-5D-Y proxy showed significant differences in the severity of cerebral palsy. However, large-scale studies using EQ-5D-Y proxy are needed because of low test-retest reliability.

Interactive Media Art has been developed a lot in digital age. Especially, the audience try to make interactions by accessing the world of art as one of main interacting figures, while they used to be totally separated from the art in traditional art. Also, it is one of exclusive features distinguished from the other art genres. In this thesis, the intercommunication process of interactive media art is classified and compared with Merleau-Ponty's corporeity phenomenology theories. Merleau-Ponty's corporeity phenomenology insists integrated perception through body against the western intelligence philosophy focusing on binomial reasons. Merleau-Ponty's corporeity phenomenology, which suggested the new perception way towards the art, is analyzed in this thesis by comparing it with detailed factors of Intercommunication process of Interactive Media Art. The Intercommunication process of Media Art is classified into , , , , . Additionally, they are studied and compared with the concept of , , , , out of Ponty's corporeity phenomenology theories. Therefore, it is concluded clearly that corporeity, synesthesia, poly sensation and spaciality drawn from Intercommunication process of Media Art have something in common with Ponty's corporeity phenomenology theories rather than the other art genre or minimalism art styles. Furthermore, a new direction of study upon modern Interactive Media Art is suggested.

Abstract The purpose of this paper is to analyze production and innovation networks of manufacturers in the rural, long-live areas of Gangwon Jeju and to suggest an ideal regional development model of rural areas in the knowledge-based information age. For this purpose, we compared the areas of Gangwon Jeju with the long-live belt areas in the rural pan of the Honan region and Gwangju Jeonju, the urban part of Honam. The findings from the study are summarized as follows. Firstly, the stronger the local networks in terms of supply of the necessary input materials and labor, the more successful the manufacturing industry is in the given area. Secondly, the more diverse and lasting the networks (in terms of the location of manufacturers, local area and national area) and cooperation agents(businesses, research institutions, the local government, the central government) they have, the more prosperous the manufacturing industry is. These results indicate that the successful development model for rural areas requires that we take the approach of fostering potential innovation capabilities of total areas by fully utilizing their innate resources so as to create an internal cooperative network and further build extensive networks encompassing external entities to create a virtual innovation cluster.
