The shift in the perspective on learning as participation draws attention to learners' identity work. This manuscript foregrounds the ongoing and fluid processes of identity, and focuses on the structure surrounding learners where identity work occurs and the expression of individual agency. From the perspective of learning as participation, we introduce Holland et al. (1998) identity-in-practice theory, as the theoretical lens that dialectically describes structure, agency and identity. The concepts representing this theory are 'figured world', 'positionality' and 'authoring self'. The figured world is a web of meaning encompassing the continuous construct/reconstruct through human actions and also exerts as the social force that shapes human actions. 'Positionality' on the other hand, means an understanding of one's social position in the world. The notion of 'authoring self', is a dimension that synthesizes the above two concepts, which describes the improvisation of one's self through the orchestration and collaboration of various social voices. Next, we analyzed and described various cases of this theory that we found within the scope of science education. However, due to the nature of this theory, which takes a sociocultural approach, international research studies cannot be simply applied to the Korean context. Therefore, we sought to expand the applicability of this theory as a methodological tool, by discussing the directions in which this theory can be used in a domestic context. It is intended that the introduction of this theory, which emphasizes multi-layered, continuous and cumulative identity work, will be used as a resource to further expand the horizon of science education reform that is required for the times.

Various studies have been conducted on cloud observation using all-sky images acquired with a wide-angle camera system since the early 21st century, but it is judged that an automatic observation system that can completely replace the eye observation has not been obtained. In this study, to verify the quantification of cloud observation, which is the final step of the algorithm proposed to automate the observation, the cloud distribution of the all-sky image and the corrected image were compared and analyzed. The reason is that clouds are formed at a certain height depending on the type, but like the retina image, the center of the lens is enlarged and the edges are reduced, but the effect of human learning ability and spatial awareness on cloud observation is unknown. As a result of this study, the average cloud observation error of the all-sky image and the corrected image was 1.23%. Therefore, when compared with the eye observation in the decile, the error due to correction is 1.23% of the observed amount, which is very less than the allowable error of the eye observation, and it does not include human error, so it is possible to collect accurately quantified data. Since the change in cloudiness due to the correction is insignificant, it was confirmed that accurate observations can be obtained even by omitting the unnecessary correction step and observing the cloudiness in the pre-correction image.

Metaverse is gaining worldwide interest, and related industries are developing rapidly. In the field of education, students' interest in metaverse is increasing, and education on metaverse-related technologies and services is required. However, since metaverse classes in universities mainly consist of theoretical education and domestic/overseas case analysis education, practical education that can apply metaverse technology to the real world is also necessary. In the cultural field, event contents such as entrance ceremonies and exhibitions are mainly produced for metaverse contents, and it is also necessary to study metaverse contents that can be sustained for a long time by people visiting regularly. In this study, educational contents that can link cultural participation in the real world with cultural participation in the metaverse were studied using the local cultural space as a medium to produce sustainable metaverse contents. The 'Metaverse Moonshin Art Museum commemorating the 100th anniversary of Moonshin's birth' program reinterpreted the real world of Changwon Moonshin Art Museum into a virtual world by collaborating with students on the Roblox. The 'Expanded Reality Moonshin Art Museum' program created an expanded Metaverse art museum that transcends time by augmenting the deceased Moonshin artist in the museum's exhibition space using HoloLens. For students studying culture-related majors, an educational program that combines metaverse education and practical training was conducted, and it is planned to be supplemented and used as a teaching plan.

In this paper, a study is conducted on the acceptable tolerance of an alignment device to reduce the optical loss caused by the alignment tolerance of a window hermetic optical connector. To increase the transmission distance of optical signals and fiber-optic communication systems, it is necessary to maintain and improve the high optical efficiency of the connectors used to bond optical fibers. In the case of the window hermetic optical connector, the optical system is aligned through an alignment device. At this time, since the two connectors are used together, each component is fixed, and further alignment is impossible. The alignment tolerance of the housing system and pin used to align the optical system of the connector causes optical loss, leading to serious problems in the fiber-optic communication system. Thus, to find the acceptable tolerance required for manufacturing the optical-connector alignment device, tolerance analysis is performed on the components of the optical connector, such as the ball lens and the window. We also implement single-mode and multimode optical-connector systems, respectively. Based on the results, we determine an acceptable tolerance value for the alignment device.

This paper explores the academic topography of the discourses on the anthropocene to delve into how the humanities can insightfully respond to the ecological crisis of the Earth through the lens of environmental humanities proposed in a 2020 book, The Anthropocene and the Humanities: From Climate Changes to a New Age of Sustainability by a scientific philosopher, Carolyn Merchant. By publishing her latest book, The Anthropocene and the Humanities, Merchant, a pioneering scholar of ecofeminism, has recently started into inquiring into the discourses on the anthropocene, meaning a geological age led by anthropos/humans. In one of her most distinguished works of 1980, The Death of Nature: Women, Ecology, and the Scientific Revolution, Merchant has revealed that the modern Western perception of nature, often identified with women, have been figuratively killing nature as well as women. Arguing in The Anthropocene and the Humanities that the anthropocene has been enacting a "second death of nature," which has been practically and technially killing nature, Merchant calls for the insight of the environmental humanities that help us to build a "sustainable livelihood" based on the "partnership" between human and nonhuman nature. This paper contemplates on what humanities can do in the era of anthropocenic planetarian crisis with the environmental humanistic alternatives in ecofeminist perspective to overcome the anthropocenic crisis aggravated by the covid-19 occurred at the point when the climate change was viscerally felt by the humans in the twenty first century.

This study delves into a question as to how the concept of corporate social responsibility (CSR) is internalized across corporations. CSR internalization refers to the process where a corporation incorporates CSR practices into its business practices. Drawn from the institutionalization process of knowledge adoption under environmental pressure, we pay attention to the roles of proximity, defined as the distance between environmental characteristics and organizational characteristics of corporations. And we argue that the extent to which a given firm is situated in the environment knowledgeable will make the firm likely to adopt CSR practices. To test this idea, we figure out when and how corporations participate in the B-Corporation Movement in the U.S., through the lens of proximity. Specifically, we subdivide proximity into geographical proximity, organizational proximity, and overlapped proximity and examine whether proximity can increase the likelihood of adopting CSR practices. With a sample of 536 start-ups which had participated in the B-Corporation Movement between 2007 and 2017, we find that the three types of proximity consistently increase the likelihood of becoming a certified B-Corp. This suggests that a corporation is highly likely to accept the concept of CSR under external pressures, along with its intrinsic motivation, which provide theoretical and practical implications on CSR internalization.

The purpose of this study is to analyze social perceptions and discourses about creating arts in the era of artificial intelligence with making an implication of responding to the emergence of artificial intelligence. We conceptually understand the principles and limitations of creating visual arts using artificial intelligence whilst this paper addresses ai art in the social context by borrowing the theoretical lens from the sociology of arts. This article considers 472 newspapers about artificial intelligence art as the main data, which are interpreted through semantic network analysis. The analysis of this research shows that it is a controversial issue regarding who/which creates the artworks between humans and computers. However, judging from the dominant influence of a group of words representing the recognition of intellectual property rights, we have detected that social awareness is formed around the perspective of considering artificial intelligence creates visual arts rather than artists. In addition, based on the close relationship between the cluster and the cluster reflecting institutional support, we confirm that the discourse about artificial intelligence art is limited to technological development and legal system maintenance. Thus, this study suggests the need for defining artificial intelligence as the medium of art and constructing policy discourses on artificial intelligence art as an artistic genre.

EBS has been producing numerous educational contents with traditional virtual studio production systems since the early 2000s and applied AR video production system in October 2020, twenty-years after. Although the basic concept of synthesizing graphic elements and actual image in real time by tracking camera movement and lens information is similar to the previous one but the newly applied AR video production system contains some of advanced technologies that are improved over the previous ones. Marker tracking technology that enables camera movement free and position tracking has been applied that can track the location stably, and the operating software has been applied with Unreal Engine, one of the representative graphic engines used in computer game production, therefore the system's rendering burden has been reduced, enabling high-quality and real-time graphic effects. This system is installed on a crane camera that is mainly used in a crane shot at the live broadcasting studio and applied for live broadcasting programs for children and some of the videos such as program introductions and quiz events that used to be expressed in 2D graphics were converted to 3D AR videos which has been enhanced. This paper covers the effect of introduction and application of the AR video production system on EBS content production and the future development direction and possibility.

With the development of virtual and augmented reality technologies, the metaverse, a digital world that provides an immersive feeling like the real world, is overgrowing. Many IT companies such as Naver, Facebook (Meta), and NVIDIA are developing innovative technologies and launching the Metaverse platform and related products on the market. However, even though it is a new business in which many global big tech companies are aggressively investing, the results are not yet precise compared to the market expectations, and the rate of increase in the number of users is gradually slowing down. This can be attributed to the lack of consideration and understanding about how to grow the metaverse ecosystem and operate & harmonize various users/components from the time the metaverse platform was designed. In order to propose a better solution to these problems, this study adopts the yin-yang and five elements theory, which was created to understand the operation logic and logic of the human world for thousands of years. This research would like to propose a theory of double lines-five elements by defining two essential spaces of the metaverse platform, online and offline, and five essential elements constituting the metaverse platform. This study intends to provide a theoretical lens on how to design and operate a platform through the double lines and five elements theory and the concept of coexistence and polarity between the five elements.

The Pseudogobio esocinus were caught at Wyuleo-ri, Gyeombaek-myeon, Boseong-gun, Jeollanamdo from April to May 2003. The fishes were incubated in transparent aquarium located at the laboratory of Chonnam National University, and their embryonic and larval development were observed. The fertilized eggs were spherical, semitransparent, and adhesive, and were $1.98{\pm}0.19mm$ (n=50) in diameter. The embryo, including 31$\sim$32 myotomes, hatched through egg membrane at 164 hrs after fertilization. The newly-hatched larvae were $4.61{\pm}0.83mm$ (n=10) in total length (TL). At that moment, yolk was not absorbed, and mouth and anus were not open. Star and spot shaped melanophores were distributed on the lens, and dorsal, ventral, and caudal parts. At 42 days after hatching, larva was $16.22{\pm}0.65mm$ (n=10) in TL. Melanophores were scaterred at head, back, and side parts. Morphological features of the embryo were transferred to juvenile stage showing similar features with those of the adult fish.
