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.

An Instruments are not only for musical usage, but also for historical, social and cultural contexts. The yanggeum instrument began to be played in Persia before the 10th century and is played in various parts of the world in the 21st century. It has been handed over for many years and played creatively beyond the boundaries of the region. In this paper, we will learn about the meaning of Korean traditional yanggeum, which preserves its original shape without any change in form or technique, through a method of musical iconography. As a method of musical Iconography for the musical instruments, we examined the data on the drawings and compared it with the literature, focusing on the origin, form and performance of the instruments. I hope that this study will not only provide a new perspective on instrument research, but also help understand the historical, social and cultural implications of the instrument. It is hoped that research on musical instruments will be done in many different ways and that the realm of musical science will be approached widely.

The object of this study is through an empirical analysis, how cultural capital at the individual level and social welfare expenditure at the national level affect the life satisfaction of the elderly. In this study method, a Hierarchical Linear Model(HLM) analysis was performed on 3,297 elderly people aged 65 and older and 9 OECD countries. As a result of analysis, first, it was confirmed that life satisfaction and social class had a significant effect. Therefore, in to increase the satisfaction of the life of the elderly, policy and practical intervention measures that can narrow the gap between social classes should be prepared. Second, the old-age pension and survivor's pension had no significant effect on life satisfaction. However, as a result of the interaction, social class has a positive effect on life satisfaction, and it was confirmed that the lower the income inequality, the more positive the life satisfaction was. In conclusion, this implies that both individuals and countries should make efforts to variously increase the life satisfaction of the elderly.

This study investigated elementary students' understanding of Earth revolution and its accompanied apparent motion of constellation in terms of spatial reasoning. We designed a set of multi-tiered constructed response items in which students described their own idea about the reason of consecutive movement of constellations for three months and drew a diagram about relative locations of the Sun, the Earth, and the constellations. Sixty-five sixth grade students from four elementary schools participated in the tests both before and after science classes on the relative movement of Earth and Moon. Their answers to the items were categorized inductively in terms of transforming frames of reference which are observed on the Earth and designed from the Space-based perspective. We analyzed those categories by the levels of spatial reasoning and depicted the change of students' levels between pre/post-tests so that we could get an idea on the preliminary developmental pathway of students' understanding of this topic. The lower anchor description was that constellations move around the Earth with geocentric perspective. Intermediate level descriptions were planar understanding of Earth movement, intuitive idea on constellation movement along with the Earth. Students with intermediate levels did not reach understanding of the apparent motion of constellations. As the upper anchor description students understood the apparent motion of constellations according to the Earth revolution and could transform their frames of reference between Earth-based view and Space-based view. The features as the case of evolutionary learning progressions and critical points of students' development for this topic were discussed.

The purpose of this study was to examine the effect of group success on organizational commitment in organizational situations. It also aimed to investigate the dynamics in the relevance of motivational attitudes to the individual and group level variables(collective efficacy, group cohesiveness). This study used a multi-level model and tested a series of hypotheses through meso-mediation procedure. The results from 613 naval officials in 36 groups provided evidence that; (1) collective efficacy mediated the relationship between group success and group cohesiveness, (2) the cross-level main effects of group success and collective efficacy were shown on vocationa[l self-efficacy, (3) group cohesiveness exerted positive influence on organizational commitment and (4) the meso-mediation effects among the variables at the multi-level were revealed. It was found that the degree of work motivation and motivational attitudes depended on the group's contextual factors, and that each group's shared perceptions on group performance outcomes could be an important motivational source and cornerstone leading to group cohesiveness. The implications and limitations of these study as well as the direction for future study were discussed.

This paper analyzes the technology transfer mechanism of companies clustered in a specific economic space from the perspective of absorptive capacity, taking the Daegu automotive parts industry as an example. According to the analysis results, The absorptive capacity of a company was found to be positively related to the supplier, channel, method, and institutional interaction of technology transfer. Low absorptive capacity limits technology transfer by reducing companies' technology search capabilities, while high absorptive capacity gives companies access to technology search and various technology transfer opportunities through formal and informal channels. These results suggest that, in the short term, it is necessary to supplement the search capabilities of companies through preemptive visiting services of local intermediaries for the vitalization of regional technology transfer, while in the long term, a policy approach focusing on enhancing the absorptive capacity of local companies is required. For effective implementation of these policies, a multi-layered governance approach corresponding to each level of companies' absorptive capacities is required in establishing an interface structure that promotes linkage between institutional actors.

This study examines the concepts and characteristics of Interculturalism and extracts artistic expressions of intercultural characteristics shown in Nouvelle Danse and Non-Danse, which were the birthplace of the contemporary dance flow in Europe. The discussion and composition of these dances will be analyzed from an intercultural perspective by selecting three works by each choreographer representing Nouvelle Danse and Non- Danse. In doing so, we would like to examine what creative acceptance was achieved based on the values and understanding in the clash and encounter between different cultures in art. Dance and interculturalism emphasize exchanges and encounters between one's own culture and other cultures. In addition, it has the potential to contribute to dance studies through the humanistic perspective of dance, as it also contains issues about diversity and identity due to exchange between cultures at the center of globalization. Therefore, the purpose of the study is to read the artistic expressions of choreographers in Nouvelle d'Anse and Non-d'Anse through intercultural understanding with an in-depth understanding and to interpret them by adding multi-layered time to the study.

This study analyzed the ignorance and prejudice with regard to African culture, which can be seen at the textbook and class course centering the geography class from 1990's to the present, and reviewed critically the related education and learning effects for mutual understanding. This study results are as follows: First, in the geographic environment contents, the image regarding huge continent, the local image regarding the various physical environments and the geographical importance as the ancient civilization birthplace were not included in the description. Second, the description regarding the African culture and history was focused to the singular African image, so the fixed concept and distorted image has been rooted into the formation of cultural meta-knowledge. Third, the negative sides rather than positive development and the past backward facts rather than changed status have been emphasized in the description regarding African resources and industry as well, so only the region surrounded with the various problems including poverty and the image as underdeveloped country have been rooted into the description. Now, real Africa view, an image for a variety of attractive and vibrant Africa rather than the same culture and characteristics of African must be learned in text books.

In this study, we studied optical properties on the layer-by-layer (LbL) assemblies consisting of Au nanorods and organic dyes. For this purpose, poly (allylamine hydrochloride), PAH and poly (styrene sulfonate), PSS were selected as ionic polymers and rhodamine B isothiocyanate (RB) was utilized as an organic dye based on its spectral overlap with plasmon band of Au nanorods. In the view point of assembling methods, RB was covalently attached to PAH, then, LbL structure of Au [PSS/PAH]2/PSS/PAH-RB was prepared by sequential coating of PAH, PSS, PAH-RB on Au nanorods. Since the prepared LbL assembly exhibits both plasmonic and fluorescent properties, we studied the mutual nanorod-dye properties by dissolving Au nanorods.
