  • The development of Internet technology has brought the era of one-man media. An individual produces content on user own and uploads it to related online services, and many users watch the content of online services using devices that allow them to use the Internet. Currently, most users find and watch content they want through search functions provided by existing online services. These features are provided based on information entered by the user who uploaded the content. In an environment where content needs to be retrieved based on these limited word data, user unwanted information is presented to users in the search results. To solve this problem, in this paper, the system actively analyzes the video in the online service, and presents a way to extract and reflect the characteristics held by the video. The research was conducted to extract morphemes based on the story content based on the voice data of a video and analyze them with big data technology.

  • The essay examines two different editions of Anne Askew's Examinations published in the sixteenth century: John Bale's the First Examination and the Latter Examination and John Foxe's Acts and Monuments, and argues that retelling and rewriting one's experience is the process of storytelling that necessitates the repetition and communication of the experience. The essay looks at the parts the sixteenth-century editors particularly rewrote or retold the original version, and discusses how Askew's story was retold, repeated, and communicated through various storytellers who delivered not only the original text but also the original experience toward larger audience. While attempting to interpret, analyze, and expand on the story she did not tell, or the story she could not tell, Bale and Foxe developed her personal and anecdotal story into a communal narrative to share. Bale wrote a weak woman's martyrology by adding his interpretation and analysis, showing the way for the readers to follow in understanding her enigmatic silence and gestures. On the other hand, Foxe made the story a more dramatic and more seamlessly flowing narrative of the heroic sacrifice of a martyr. Foxe filled the room left by Askew's silence with directly quoted conversations and the graphic that could help explain what was between the lines. Apart from the rewritings of the reformists, the essay focuses on the fact that the editing, rearranging, and reinterpreting process already started with Askew's own writing. Although Askew declares herself an objective recorder of the series of events, her writing is carefully constructed with complex ideological fractures and rhetorical tactics, and her experience is tailored to fit a particular purpose. Along with Bale's and Foxe's rewritings, Askew's story of a reading woman should be also read as an intentional and interpretative storytelling on her own experience.

  • The spread of COVID-19 and the advent of the Fourth Industrial Revolution have significantly affected the nature of college education causing many changes to the way it is conducted. One of these changes is the expansion of online education. The purpose of this study was to analyze the difficulties experienced by learners due to the transition to rapidly expanding online education at domestic universities, and to seek ways to support their learning through this new online platform. Results of a questionnaire showed that learners experienced difficulties in their interactions with professors because of the rapid transition to online education without adequate preparation. It was determined that there were not enough opportunities for communication between learners and professors as a result of non-face-to-face online education, and that learners did not receive Q&A or feedback quickly enough. The study also examined ways to ways to improve the effectiveness of online learning. Students showed a high preference for items such as "appropriate guidance regarding announcements such as lecture schedules," "providing lecture notes as learning materials."

  • The flower, a symbol of beauty representing beauty, exists as an aesthetic object throughout the history of mankind, and is one of the motifs most often used in plastic art. In this way, flower art is an art that embodies a form based on the theme of flowers. The flowers played a role in expressing human happiness and love by harmonizing beautifully with each other in shape and color. The flower pattern containing this symbolism is beautiful and excellent in decoration, and is applied not only to household goods, but also to art and fashion. The flower pattern is the most preferred pattern among patterns, and it is widely used regardless of the four seasons by changing the color according to the color and flowering time, and it is effective in stimulating the symbolism and psychological sense of humans, so it is used in design in various fields. In this study, the flower pattern, which is a symbol of beauty representing beauty and the motif of art, has been traditionally used in Korea, and is still loved in fashion and art even in modern times. We hoped to be active, and through this study, we tried to develop our own unique flower pattern and lay the groundwork for it to be commercialized.

  • Machine learning techniques using visual data have high usability in fields of industry and service such as scene recognition, fault detection, security and user analysis. Among these, user analysis through the videos from CCTV is one of the practical way of using vision data. Also, many studies about lightweight artificial neural network have been published to increase high usability for mobile and embedded environment so far. In this study, we propose the network combining the object detection and classification for mobile graphic processing unit. This network detects pedestrian and face, classifies age and gender from detected face. Proposed network is constructed based on MobileNet, YOLOv2 and skip connection. Both detection and classification models are trained individually and combined as 2-stage structure. Also, attention mechanism is used to improve detection and classification ability. Nvidia Jetson Nano is used to run and evaluate the proposed system.

  • Recently, metaverse is becoming increasingly important in coding education. One of the most important elements in metaverse is interaction in 3D virtual space. However, most existing education methods still utilize metaverse for unidirectional education without making use of interaction. This paper proposes a new method of using metaverse for bidirectional coding education. In the metaverse virtual space, a professor and students are able to share their PC screens for monitoring purposes. Also, once a student sends a request to the professor, the professor can immediately provide proper feedback (such as source codes correction) through access control. This metaverse virtual space is able to include more than two professors that allows for a many-to-many coding education. This paper presents a way of constructing the metaverse environment and teaching scenario, followed by the descriptions of the advantages and requirements for the proposed method.

  • This study investigates the effects of the operation of science activity program on scientific literacy focusing on science cultural literacy and core competencies for pre-service teachers. 255 pre-service teachers of K University participated, and the effects of the program were examined through a paired-sample t-test with one group pretest-posttest design for science cultural literacy. Only the post-test was conducted on core competency growth perception, and differences in growth perceptions by competency were compared using ANOVA. As a result of the study, the average of pre-service teachers was higher than the pre-test for science culture literacy, and this difference was statistically significant (p<.05). In the core competency growth perception, 70.6% of pre-service teachers reported growth in scientific communication ability, and as a result of the post-hoc test using LSD, it shows statistically significant growth compared to other competencies (p<.05). Through this, it was possible to confirm the educational value of the science activity program as a way to develop pre-service teachers' scientific literacy.

  • In the coming future, anyone using the Internet will have more than one NFT. Unlike FT, NFT can specify the owner, and tracking management is easier than FT. Even in the 2022 survey, WPA2 is the most widely used wireless protocol worldwide to date. As it is a protocol that came out in 2006, it is a protocol with various vulnerabilities at this time. In order to use WPA2-EAP or WPA3 (2018), which were released to compensate for the vulnerabilities of WPA2, additional equipment upgrades are required for STA (station) and AP (access point, router), which are connected devices. The use of expensive router equipment solves the security part, but it is economically inefficient to be introduced in Small Office Home Office (SOHO). This paper uses NFT as a means of authentication and uses the existing WPA2 as it is without equipment upgrade, defend crack tools of WPA2 that have been widely used so far and compared to the existing WPA2, it was shown that it was not difficult to actually use them in SOHO.

  • Purpose: This study is descriptive survey research on the analysis of nurses' perception of the 4th industrial revolution and the importance and performance of future core nursing competencies in a tertiary hospital located in Seoul. Methods: Data were collected from 149 nurses with more than a year of work experience and analyzed using descriptive statistics, t-test, one-way ANOVA, and Importance Performance Analysis(IPA) with the IBM SPSS/WIN 25.0 program. Results: The nurses' perception of the 4th industrial revolution was 3.23±0.71 out of 5 points. The importance of future core nursing competencies was 4.31±0.48, and the performance of it was 3.47±0.54. The analysis results of IPA showed that A (area of continuous maintenance) included critical thinking, problem-solving skills, teamwork and collaboration, evidence-based practice, communication, quality improvement and safety, professionalism, self-regulation and self-management, and personal literacy. The specific competencies were not included in B (area of priority improvement). Creativity, informatics, healthcare policy, leadership, research ability, and continuing education were included in C (area of progressive improvement). Knowledge and patient-centered care, ability to manage resources as well as professional, legal, and ethical responsibility were included in D (area of overinvestment). Conclusion: The nurses seemed not to be fully prepared for the 4th industrial revolution. However, they were well aware of the importance of the future core nursing competencies. Therefore, if nurses increase the performance of core competencies in order of priority according to the IPA results, they will be able to independently lead the changing nursing field.

  • This study aims at exploring the transnational care for family members back home among the Nepalese marriage immigrant women in Korea on the bases of some transnational care practices like remittances, virtual intimacy through information and communication technologies, visit to Nepal, and invitation of family members to Korea. This study argues that in order to understand migrant women's care practices properly, Nepalese marriage immigrant women should be considered as 'being in-between' the societies and cultures of Nepal and Korea. This study identifies the characteristics of transnational care practices of Nepalese women are closely related to the role expectation for the eldest daughter as well as whether or not migrant women have children, jobs, and original family member in Korea. Furthermore, this study highlights that migrant women's transnational care practices should be considered as 'reciprocal exchange of cares' between marriage women and their family members rather than one-way benefits going to the latter.
