Recently, the use of generative AI has become more active in university education, but jewelry design education and research using generative AI are still insufficient. Accordingly, we would like to discuss the possibilities and limitations of visualization of jewelry design ideation and expression using generative AI in the jewelry design development education and ideation stage, as well as the experience and application of generative AI by college students. To analyze the impact of generative AI on the learning experience, it was analyzed from the perspectives of 'usability', 'usefulness', 'reliability', and 'satisfaction'. As a result, generative AI confirmed positive results in terms of usability and usefulness to trainees, and confirmed the potential for effects using personalized education and collective intelligence. The combination of jewelry design education and generative AI is part of convergence education, and the significance of this study is to lay the foundation for effective use in jewelry design education by analyzing learners' experiences and perceptions of using generative AI. This kind of education reflects the trends of the times for nurturing future society's talents and will contribute to the promotion of learners' broad creative thinking.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease caused by both genetic and environmental factors. Fludarabine is a selective inhibitor of signal transducer and activator of transcription 1 (STAT1). Recently, STAT1 inhibitors have been considered potential treatments for SLE, due to the relationship between its pathogenesis and STAT1 pathway-mediated cytokines such as interferons. In the current study, we evaluated the therapeutic effects of fludarabine in an SLE animal model and explored its effects on T cell responses. 12-week-old C57BL/6 mice with topically administered R848 exhibited lupus-like phenotypes. Disease activity, such as proteinuria, autoantibody levels, immunoglobulin titers, the histological score, and C3 deposition, greatly improved with fludarabine treatment. In addition, fludarabine inhibited CD4⁺ T cells and T helper 1 (Th1) cells in the spleen and significantly decreased the differentiation of Th1 cells in vitro. These results indicate that Th1 cells play a critical role in the pathogenesis of lupus nephritis (LN). Thus, fludarabine exerted therapeutic effects on lupus animal models by suppressing Th1 cells via STAT1 inhibition. We propose that targeting STAT1 signaling using fludarabine could be an effective therapy for treating LN.

Reading fluency refers to the ability to read sentences or paragraphs accurately, quickly, and with appropriate prosodic expression. Most reading fluency assessments exclude expressive ability because it is difficult to objectively measure. Therefore, in this study, we examined all elements of reading fluency by analyzing prosodic characteristics of reading scenario texts to maximize expressive reading. The subjects were 30 male students in the first and second grades of middle school (15 normal and 15 poor readers). To analyze the accuracy aspect, error types at the syllable level were analyzed for each group, and related acoustic variables were measured and examined in terms of prosodic aspects. The reading accuracy analysis showed that the poor reading group had a higher error rate than the normal. In terms of error types, the normal group showed the order of 'substitution>omission>correction>insertion>repetition', whereas the poor reading group was in the order of 'correction>substitution>repetition/insertion>omission'. For the speech tempo, the dyslexic students were slower than the typical students for all sentence types. The prosodic variables also showed a high frequency of accentual phrases (AP) and intonation phrases (IP) in sentences along with a wide intensity range.

Chung's equation-IX and Chung's equation-XII were utilized to predict the fire risk and evaluate fire risk ratings for five types of wood: white ash, hard maple, willow, fraxinus mandschurica, and sagent cherrys. The combustion tests were conducted using a cone calorimeter test method by ISO 5660-1 standards. The fire risk and fire risk rating (FRR) were compared with fire risk index-IX (FRI-IX) and fire risk index-XII (FRI-XII). The results yielded a fire performance index-XI (FPI-XI) ranging from 0.44 to 1.05 and a fire growth index-XI (FGI-XI) ranging from 0.89 to 3.11. Also, the fire risk index-XII (FRI-XII), indicated fire risk rating, exhibited an increasing order of sagent cherry (0.85): Grade A ≈ PMMA (1): Grade A ≈ white ash (1.22): Grade A ≈ hard maple (1.53): Grade A < willow (4.00): Grade C < faxinus mandschurica (7.07): Grade D. Additionally, the fire risk index-IX (FRI-IX) was PMMA (1): Grade A ≈ hard maple (2.28): Grade A ≈ sagent cherry (3.24): Grade A < white ash (5.73): Grade B < fraxinus mandschurica (10.29): Grade C ≪ willow (48.30): Grade G. In general, the willow and fraxinus mandschurica showed the highest fire risk. In conclusion, although the expression of the index is different as shown based on the criteria of FRI-IX and FRI-XII, predictions based on fire risk assessment of combustible materials showed a similar tendency.

This study identified objective placeness throughout the writing of Na, Hye-seok, who was Korea's first female Western painter and early modern writer, and analyzed her spatiality around two keywords, "confined space" and "delay space." The investigator applied the concept of gender geography, which maintains that place experiences organize existence, and demonstrated the intrinsic aspects of placeness. First, confined spaces expressed the institutional contradictions of Joseon with the analogy of collapse and extinction. Inns and boarding houses were daily spaces and also temporary places of residence that she had to leave some day. Gyeongseong was a hybrid place of both success and failure. Secondly, Japan was a space of growth to study modernity and a delay space to escape from fear for Na. Her Western experiences underwent the procedure of discovering otherness inside a civilized state instead of self-colonization and asking questions about the places where she belonged. Na's place experiences and their connotations revealed in her writing show a gap between the ideal and reality of a subject facing her given destiny and between her inner conflicts. The present study demonstrated the daily conditions, social status, and characteristics of women through spaces beyond ideological placeness as a common idea, thus holding its significance. The specific daily and multiple nature produced in relations between a certain subject and the existential situation of a place will play significant roles in the theoretical extension of gender discourse in the future.

The purpose of the study was to investigate and compare the effects of school violence victimization on school violence perpetration for each group of different out-of-home care types: institutional care, group home, and foster care. Furthermore, the study explored the protective factors for children in each type of the care. Using data from the Panel Study on Korean Children in Out-of-Home Care (PSKCOC), we utilized a sample of 458 children who participated in both the first- and the second-wave surveys. As possible protective factors, this study examined internal, caregiver, and external support-related factors. Data were analyzed using multiple regression analysis and the pick-a-point approach. The results were as follows. First, among the three groups of children, school violence victimization of children was shown to influence violence perpetration only in the institutional care group. Second, among examined possible protective factors, only the self-expression of children among the institutional care group showed buffering effects of victimization. Based on these results, practice implications for children in out-of-home care were discussed.

The purpose of this study was to develop instructional programs aimed at enhancing middle school students' understanding of evolutionary concepts using a step-by-step writing strategies and an applicable evaluation rubric for evolutionary concepts. To achieve this, a step-by-step writing instructional model (PEECE) was devised as a method for scientific writing, and essential evolutionary core concepts were selected considering the middle school curriculum's coverage of biological evolution. Six evolutionary core concepts-variation, inheritance of variation, differential survival and reproduction, microevolution, and macroevolution-were chosen, with each serving as the focus of a lesson in a four-lesson program following the PEECE lesson model. The program was implemented with 16 students in a co-curricular middle school class. Pre- and post-lesson evolutionary concept checklists were administered to diagnose and compare the level of evolutionary concept understanding. Additionally, students' writing materials for each evolutionary core concept were collected, scored using an evolutionary concept evaluation rubric, and thoroughly analyzed. The results indicated that the step-by-step writing strategy effectively enhanced understanding of the six evolutionary core concepts and reduced cognitive biases and misconceptions about evolution. Contrasted with the optional evolution concept test, the descriptive writing activity provided a more tangible insight into students' scientific concepts, biases, and misconceptions, facilitating teachers' assessment of understanding and feedback provision. Moreover, the jointly developed evaluation rubric offered specific scoring criteria, enabling objective assessment without subjective influence, allowing analysis and scoring of students' writing materials across evaluation areas for collecting fundamental data.

These studies were aimed at clarification of genetic and ecological variation in culm length, panicle length and plant height of the $\textrm{F}_2$ plants in some selected crosses made between semi-dwarf rice varieties and tall Japonica ones. One Indica semi-dwarf, Taichung Native 1, one Indica $\times$ Japonica hybrid, IE51 and one Japonica semi-dwarf, Tankanbaekmang were used as short-gene donors while two of medium maturity varieties, Jinheung and Kwanok and one late veriety, Palkweng were used as the corresponding counterpart of respective dwarf varieties in a series of crosses. Five different crosses, Kwanok $\times$ Tankanbaekmang, Palkweng $\times$ Tankanbaekmang, Jinheung $\times$ T(N)1, Kwanok $\times$ T(N)1 and Kwanok $\times$ IE51, were made among the above six varieties. The $\textrm{F}_2$ plants of these crosses together with the concerned parental varieties were grown under several different conditions including three levels of each nitrogen and planting space, three planting seasons and three locations in 1968, to investigate variation in length of culm and panicle, and plant height. On the other hand, the F$_3$ progenies which were derived from the shortest 10 percent of the plants of three $\textrm{F}_2$ populations, Kwanok $\times$ T(N)1, Jinheung $\times$ T(N) 1 and Kwanok $\times$ IE51 grown in the previous year, were compared each other on the basis of selection efficiency in culm length. The experimental results could be summarized as follows; 1. Genetic behavior A. It was revealed that Tankanbaekmang, one of Japonica dwarf has a simple recessive gene responsible for short culm expression, showing a typical segregation ratio of three tall to one short culm plants in $\textrm{F}_2$ generation of the crosses either with Kwanok or Palkweng. B. In the both combinations, segregation pattern of the panicle length was exactly same as that of culm length. It seems that the same gene controls both culm length and panicle length. C. No difference between segregation of culm length and plant height in the above crosses was observed. D. T(N)1, one of Indica semi-dwarf did not show such a simple genetic behavior as detected from the crosses with Tankanbaekmang in segregation of culm length but formed a continuous and normal distribution curve. Therefore, some nonallelic genic actions might be involved in expression of culm length of the counterpart varieties of T(N)1. In particular, a transgressive segregation appeared toward the direction of longer culm length in case of Jinheung $\times$ T(N)1. The genetic behavior of panicle length and plant height generally coincided with that of culm length in all the cases. E. IE51 demonstrated exactly the same genetic behavior as that of T(N)1 when this variety was crossed with Kwanok. It was clearly clarified that the simple recessive gene controlling dwarfism from T(N)1 was well incorporated into this variety. 2. Ecological variation A. In general, there was a decreasing tendency in culm length and plant height of rice plant as seeding delayed while it was not so noticeable in panicle length. The decreasing magnitude varied from variety to variety and from cross to cross. Genetic behavior of the culm length and related characters of these materials was not disturbed by the variation of seeding season, nitrogen level, planting space and experimental location. E. The elongation mode of the upper three internodes was very similar to the segregation mode of culm length, panicle length and plant height in $\textrm{F}_2$ populations of . all the crosses investigated in this study. Accordingly, this result confirmed that the roles of the upper three internodes are very important in manifesting plant stature in rice. C. The effect of nitrogen on culm length and the related other two characters seemed to be meager. However, it was true to show an increasing tendency of those characters as nitrogen level got increased from 4 kg to 12kg per l0a, with different magnitude depending upon variety or cross. D. Also, the effect of planting space on culm length, panicle length and plant height was relatively small in all the cases. Those characters varied again depending upon variety or cross. However, a general increasing tendency was detected in manifestation of those traits under denser planting space condition. E. All the parental varieties produced shorter culm, panicle and plant height when they were grown at the lower latitude locations. It might be attributed to the fact that their reproductive growth accelerated with increased temperature prevailing at the lower latitude locations such as Iri and Mi1yang. On the countrary, $\textrm{F}_2$ population reacted differently to the different locations from the parental varieties. All the $\textrm{F}_2$ plants produced the longest culm, panicle and plant at Milyang. 3. Selection efficiency A. The heritability of culm length in Kwanok $\times$ T(N)1, Kwanok $\times$ IE51 and Jinheung$\times$T(N)1 was 92 percent, 74 percent and 55 percent, respectively. B. The actual genetic advance for culm length obtained from the progeny lines of the selected plants(10 precent) from the $\textrm{F}_2$ generation, was comparable to the expected advance calculated from the original $\textrm{F}_2$ populations. As compared with the $\textrm{F}_2$ population, the $\textrm{F}_3$ plants of Kwanok $\times$ T(N)l shortened on the average by 20.8cm, those of Kwanok $\times$ IE51 did 8.7cm and those of Jinheung$\times$T(N)1 20.0cm, respectively. C. Panicle length of the populations was differently affected from one cross to another by the selection based upon culm length in $\textrm{F}_2$ Kwanok $\times$ T(N)1 did not show any noticeable shortening of its culm length due to the selection pressure. On the other hand, both Kwanok $\times$ IE51 and Jinheung $\times$ T(N)1 showed a considerable shortening of their panicles in case of selection for culm length. Based upon the above results, it could be concluded that the ecological variation in culm length, panicle length and plant height was relatively small and fallen within the range of genetic variation. Considering from the fact that the simple recessive gene governing short height of Tankanbaekmang always accompanied with some undesirable characters such as short panicle and extremely small grain, the short gene of T(N)1 seemed to be more useful as dwarf gene source since it did not carry short gene together with such undesirable traits.

This paper studies the time-space and appreciation of the performance culture of Gwanseo region, which is considered to have formed a characteristic culture in late Joseon period. For this purpose, 4 gasa written in hangeul (Korean alphabet), as well as 4 yeonhaeng gasa, 108 articles of Gwanseoakbu were examined. Plus, among the 9 types of yeonhaengrok (Documents of Performance culture) written in Chinese character, those parts which describe the performance traits have been analyzed. Then, 'main list of terminology' has been deduced based on the categorization according to the following points : 1) subjects of performance and appreciation 2) time and period of performance 3) space of performance 4) contents of performance 5) background and motive for performance and 6) method of performance. Through this process, various 'nouns' and 'predicate verbs' in relation to performance culture emerged, which were systemized according to types of performance elements and categories. Major terminology includes predicate verbs and symbolic verbs such as nokuihongsang,' 'baekdaehongjang,' 'jeolsaekgeumga,' 'cheonga,' 'hwaryu,' 'gamuja,' and 'tongsoja,' as well as the terms already known such as gisaeng, iwon, yangbang, akgong, and jeonak, which refer to musicians and dancers. Subjects of performance were divided into performers and listeners, categorized into concert, music, and dance, according to performance form. In the case for music, it was divided into instrumental or vocal, solo or accompanied (byeongju, self-accompaniment). In the case for vocal music, noteworthy was the inclusion of profesional artist's singing (called gwangdae or uchang). The record of 23 names of popular artists from Gwanseo region, with mention of special talents for each person, reflects the degree of activeness and artistic level of the province. Depending on the appreciating patrons, the audience were indicated as the terms including 'yugaek (party guest),' jwasang,' 'on jwaseok,' and 'sonnim (guests).' It seems that appraisal for a certain performance was very much affected by the tastes, views, and disposition of the appreciating patrons. Therefore it is interesting to observe different comparative reviews of concerts of different regions given by literary figures, offering various criticism on identical performance. In terms of performance space, it has been divided into natural or architectural space, doing justice to special performance sites such as a famous pavilion or an on-the-boat performance. Specific terms related to the scale and brightness of stage, as well as stage props and cast, based on descriptions of performance space were found. The performance space, including famous pavilions; Yeongwangjeong, Bubyeokru, Baeksangru, Wolparu, and Uigeomjeong, which are all well-known tourist sites of Gwanseo province, have been often visited by viceroys. governors, and envoys during a tour or trip. This, and the fact that full-scale performances were regularly held here, and that more than 15 different kinds of boats which were used for boat concert are mentioned, all confirm the general popularity of boat concerts at the time. Performance time, categorized by season or time of day (am/pm/night) and analyzed in terms of time of occurrence and duration, there were no special limitation as to when to have a performance. Most morning concerts were held as part of official duties for the envoys, after their meeting session, whereas evening concerts were more lengthy in duration, with a greater number of people in the audience. In the case of boat concert, samples include day-time concert and performances that began during the day and which lasted till later in the evening. Major terminology related to performance time and season includes descriptions of time of day (morning, evening, night) and mention of sunset, twilight, moonlight, stars, candles, and lamps. Such terms which reflect the flow of time contributed in making a concert more lively. Terminology for the contents of performance was mostly words like 'instrumental,' 'pungak,' or 'pungnyu.' Besides, contextual expressions gave hints as to whether there were dance, singing, ensemble, solo, and duets. Words for dance and singing used in Gwanseo province were almost identical to those used for gasa and jeongjae in the capital, Hanyang. However, many sentences reveal that performances of 'hangjangmu' of hongmunyeon, sword dance, and baettaragi were on a top-quality level. Moreover, chants in hanmun Chinese character and folk songs, which are characteristic for this region, show unique features of local musical performance. It is judged that understanding the purpose and background of a performance is important in grasping the foundation and continuity of local culture. Concerts were usually either related to official protocol for 'greeting,' 'sending-off,' 'reports,' and 'patrols' or for private enjoyment. The rituals for Gwanseo province characteristically features river crossing ceremony on the Daedong river, which has been closely documented by many. What is more, the Gwanseo region featured continued coming and goings of Pyeongan envoys and local officers, as well as ambassadors to and fro China, which required an organized and full-scale performance of music and dance. The method of performance varied from a large-scale, official ones, for which female entertainers and a great banquet in addition to musicians were required, to private gatherings that are more intimate. A performance may take the form of 'taking turns' or 'a competition,' reflecting the dynamic nature of the musical culture at the time. This study, which is deduction of terminology in relation to the time-space and appreciation culture of musical performances of Gwanseo region in late Joseon period, should be expanded in the future into research on 'the performance culture unique to Gwanseo region,' in relation to the financial and administrative aspects of the province, as well as everyday lifestyle. Furthermore, it could proceed to a more intensive research by a comparative study with related literary documents and pictorial data, which could serve as the foundation for understanding the use of space and stage, as well as the performance format characteristic to Korean traditional performing arts.
