Background: The purpose of this study was to evaluate the composition of the crystal phases of various calcium silicate-based materials (CSMs): ProRoot white MTA^Ⓡ (mineral trioxide aggregate) (WMTA), Ortho MTA^Ⓡ (OM), Endocem MTA^Ⓡ (EM), Retro MTA^Ⓡ (RM), Endocem Zr^Ⓡ (EN-Z), Biodentine^TM (BD), EZ-seal^TM (EZ), and OrthoMTA III (OM3). Methods: In a sample holder, 5 g of the powder sample was placed and the top surface of the material was packed flat using a sterilized glass slide. The prepared slides were mounted on an X-ray diffraction (XRD) instrument (D8 Advance; Bruker AXS GmbH, Germany). The X-ray beam 2θ angle range was set at 10~90° and scanned at 1.2° per minute. The Cu X-ray source set to operate at 40 kV and 40 mA in the continuous mode. The peaks in the diffraction pattern of each sample were analyzed using the software Diffrac (version 2.1). Then, the peaks were compared and matched with those of standard materials in the corresponding Powder Diffraction File (PDF-2, JCPDS International Center for Diffraction Data). A powder samples of the materials were analyzed using XRD and the peaks in diffraction pattern were compared to the Powder Diffraction File data. Results: Eight CSMs showed a similar diffraction pattern because their main component was calcium silicate. Eight CSMs showed similar diffraction peaks because calcium silicate was their main component. Two components were observed to have been added as radiopacifiers: bismuth oxide was detected in WMTA, OM, and EM while zirconium oxide was detected in RM, EN-Z, BD, EZ, and OM3. Unusual patterns were detected for the new material, OM3, which had strong peaks at low angles. Conclusion: It was caused by the presence of Brushite, which is believed to have resulted in crystal growth in a particular direction for a specific purpose.

The purpose is to derive its aesthetic characteristics by objectifying the visual image of the YouTube campaign into adjectives. As a result, we intend to identify advertising strategies that use them as basic data for setting fashion design concepts. A group of experts in fashion majors watched each of them, wrote adjectives, and collected 75 adjectives. By analyzing the frequency of adjectives, aesthetic characteristics were derived with adjectives recording the upper number of times, and the results were obtained that they had the characteristics of deconstruction. The conclusions of this study are as follows. First, Tamburin's Jenny appeared to be strange, scary, rambling and charming. Among the internal meanings of deconstruction due to spatial, social, and psychological distance from consumers, it can be said that T.P.O's mutual textuality and play of interaction. Second, Gucci Cruise be chosen rural, strange, wild, unharmonious, and difficult, which is a mixture of intertextuality and play of T.P.O. Third, The Excise Gucci Campaign parodies that juxtaposes six films directed by Stanley Kubrick, making them strange, retro, difficult, interesting, and wrong. Deconstructionist de-genre and de-boundary Fourth, Kenzo World is weird, dynamic, wrong, difficult, difficult, and confused, which correspond to T.P.O's interactive textuality, play of the second half, and destruction and decomposition among the external expressions of deconstruction. Fifth, Burberry Hero emphasized the aesthetic value of traditional men, so it was ostensibly wild, free, powerful, sensual, and fantastic. Compared to the lifestyle of men who usually work at work, this corresponds to play of second best.

The purpose of this study is to investigate the public perception of Gorpcore through Big Aata analytics. The study was conducted based on the collection of Big Data on the word 'Gorpcore' through Textom from July 24, 2017 to March 31, 2023. As a result, 63,386 words were collected from a total of 18,879 posts, and the top 50 words were determined based on frequency of appearance. Based on the collected words, centrality measures and CONCOR algorithm were performed in Ucinet 6. The research results are as follows. 1) The frequency of appearance was high in the order of 'Gorpcore look', 'fashion', 'coordination', 'clothes', 'outdoor', 'Musinsa', 'look', 'trend', 'brand' and 'ahjussi (middle-aged old man in Korean)'. These words had high TF-IDF scores, which leads to the conclusion that these are key words that are recognized as important. 2) Network centrality shows that 'Gorpcore look', 'fashion', 'outdoor', 'coordination', 'clothes', 'trend', 'look' and 'style' have a high correlation with other words. Through this, it was found that the public thinks it is important to create a variety of fashions by styling high-performance outdoor wear and casual wear, and that they are highly interested in clothes and in brands leading the Gorpcore trend. 3) As a result of the CONCOR algorithm, four significant groups were formed. The words that appear in each group are as follows. Group 1 - 'outdoor', 'Gorp', 'Normcore', 'hiking', 'functionality', 'new', 'sports', 'casual wear', 'activity', 'generation', 'collaboration'. Group 2 - 'fashion', 'trend', 'look', 'brand', 'style', 'shoes', 'ugly', 'item', 'trend', 'product', 'Salomon', 'padded jacket', 'stylishness', 'utilization', 'Winter', 'street', 'design', 'retro', 'popular', 'styling'. Group 3 - 'Gorpcore look', 'coordination', 'Musinsa', 'windbreaker', 'recommendation', 'Arcteryx', 'pants', 'man'. Group 4 - 'clothes' 'ahjussi', 'jacket', 'launching', 'spring', 'The North Face', 'collection', 'utility', 'jumper'. As a result, it can be seen that the Gorpcore is also regarded as a part of outdoor, fashion, coordination, and casual wear.

This study aimed to explore sustainable fashion design plans and directions by analyzing Marine Serre's collection. Previous research was reviewed to derive classifications of the aesthetic characteristics of sustainable fashion design. This classification was then used to analyze the characteristics of the Marine Serre collection. Design analysis was conducted on Marine Serre's 2018 FW to 2023 SS collections. Marine Serre's sustainability characteristics are functionality, surprise, handicraft, and inclusion. The results are as follows. First, functionality is the highest among the four characteristics and includes the functionality of movement, the functionality of form, and futurism. This characteristic was observed in the use of all-in-one body suits, pockets, and workwear, showing the will and values of designers who value daily activity. Second, surprise includes the scarcity of materials and the unexpectedness of composition. The value of the clothing is enhanced by the use of scarce materials not typically used in clothing. In addition, Marine Serre is highly regarded for expanding clothing into life by incorporating material upcycling into the theme of the collection. Third, handcrafted features include exaggerated decorations, logo, retro designs, and natural properties, and intentional utilization is differentiated. Marine Serre's signature pattern suggests a suitable expression for the fabric to use the crescent moon for the season. Fourth, the collection expresses themes of inclusivity and cultural diversity. The results indicate that Marine Serre wants to contribute to a better future characterized by global coexistence.

This study aims to examine the expressive characteristics of the New Chinese style in the collection of Chinese fashion designer Ziggy Chen, analyze the inner meaning, and suggest a new direction in Chinese fashion design. As a research method, the background and concept of New-Chinese style occurrence were examined through previous studies, and the characteristics of the New Chinese style expression in fashion were investigated. The characteristics of the New Chinese style were summarized as cultural tradition, historical ethnicity, and pluralistic convergence. Based on these contents, the characteristics of the New Chinese style expression in Ziggy Chen's men's fashion design were analyzed. The data collection range was selected as the range of 20 seasons collected from 2012 S/S to 2022 A/W, which was collected on fashion sites and the brand's official Instagram. The analysis results are as follows. First, subcultural resistance is a retro and ragged decadence formed by combining punk elements and industrial styles based on the clothing styles of lower-class Chinese people in the 17th and 90s. Second, cultural traditionality was influenced by traditional culture by mainland Chinese designers, who expressed the conservative presence of tradition and the Chinese style by looking at it from an oriental perspective. Third, historical ethnicity forms a Chinese fashion culture in which the national spirit and the development of the times coexist, while traditional culture and contemporary social values develop in harmony. Fourth, traditional fashion develops by combining a contemporary aesthetic sense and lifestyle with pluralistic convergence.

이 연구의 목적은 4가지 규산 칼슘계 시멘트를 대상으로 물리적 특성을 비교하고 평가하는 것이다. 2종의 분말-용액 혼합형 재료인 RetroMTA^® [RTMX], Endocem^® MTA Zr [EZMX] 그리고 2종의 기혼합형 재료인 Well-Root^TMPT [WRPR], Endocem MTA^® premixed [ECPR]를 사용하여 경화시간, 용해도 및 압축강도를 비교하였다. 가장 짧은 경화 시간은 EZMX (123.33 ± 5.77초)에서 관찰되었으며, RTMX (146.67 ± 5.77초), ECPR (260.00 ± 17.32초) 및 WRPR (460.00 ± 17.32초) 순으로 증가하였다. 가장 높은 용해도는 WRPR (9.01 ± 0.55%)에서 관찰되었으며, RTMX (2.17 ± 0.07%), EZMX(0.55 ± 0.03%) 및 ECPR (0.17 ± 0.03%) 순으로 감소하였다. 또한 압축강도는 ECPR(76.67 ± 25.67 Mpa)에서 가장 높게 나타났고, WRPR (38.39 ± 7.25 Mpa), RTMX(35.07 ± 5.34 Mpa), EZMX (4.07 ± 0.60 Mpa) 순으로 감소하였다. 결론적으로 기혼합형 규산 칼슘계 시멘트들은 분말-용액 혼합형에 비해 긴 경화 시간을 나타내었다. 용해도 실험 결과 가장 낮은 용해도를 보인 ECPR과 가장 높은 용해도를 보인 WRPR에서 통계적 차이가 관찰되었다(p < 0.0083). 압축강도 실험결과 가장 낮은 압축 강도를 보인 EZMX와 가장 높은 압축 강도를 보인 ECPR에서 통계적 차이가 관찰되었다(p < 0.0083). ECPR은 분말-용액 혼합형에 비해 긴 경화 시간을 나타내지만, 미리 혼합되어 있어 혼합 시간이 필요하지 않고 용해도와 압축 강도가 개선되었으므로 임상 사용 시 선택될 수 있는 유망한 재료이다.
