With YouTube’s overwhelming share of the market, research on analyzing the types of content on YouTube is essential. An analysis of major global fashion YouTubers that the types of video content could be largely classified into three main categories: Fashion, beauty and daily life. The fashion category was subdivided into styling and fashion product review content type. The beauty category was subdivided into tutorials, beauty product reviews, and beauty tip content types. The daily life category was subdivided into daily sharing, consultation, and Q & A content types. Video content within fashion YouTuber channels is accompanied by expertise in fashion and beauty. At the same time, videos on daily life are uploaded, and through interactive communication with viewers, YouTubers form an intimate bond with subscribers. Content emphasizing entertainment, not just information delivery that introduces fashion products, is attracting growing interest among subscribers. This study analyzed the content of the increasingly popular fashion YouTuber channels and determined its important characteristics. The study makes a significant contribution to academic research by laying a foundation for future studies of YouTube content in the fashion field. Since differences in country of birth and race among YouTubers may influence content production, follow-up research will be conducted on the types and characteristics of domestic fashion YouTubers.

The purpose of this study was to analyze the current status and contents of color-related education programs as lifelong education and to determine the necessity of color education and directions for future development. The findings of this study, first show that the general welfare center, which is striving to develop abilities and promote welfare, was opened mainly for professional education, rather than hobbyoriented education. Accordingly, pricing was set at a lower level than the three institutions and centers, but without a variety of programs or hobby-oriented courses. Second, as the purpose of the set-up is to be established, the general welfare center should be considered an area for hobbies along with expertise, and various courses should be opened. Although the department store’s cultural center focused on programs for cultural and leisure use and promotion, it is necessary to extend the program to attempt to approach it in a short-term process rather than a one-time class. The lifelong education center established as a subsidiary of the university’ was opened as an area for of painting such as oil painting and watercolor and drawing which have much in common school should learn and start basic theory and practice, so there was much difference. Third, if it is changed to a developed form of color-oriented education according to the purpose of each center and institution presented in the results of this research, a good response will be possible to further improve the quality of life and develop professionalism and creativity.

The purpose of this study was to develop a workwear design that takes into account the characteristics of people with severe developmental disabilities who can engage in vocational activities. The aim was to identify needs according to the specific characteristics of people with severe disabilities to design work clothes and develop products according to universal design guidelines. This research method was conducted through representative interviews from a company employing people with severe disabilities in Daegu to determine the requirements for workers-related work clothes, and then applied universal design guidelines to perform appropriate design. The results of the study show that the hygiene and warmth of clothing are important for people with developmental disabilities. Therefore, the use of bright materials is required. Second, people with brain lesions often have low body temperature due to difficulties with blood circulation, for which warmth is a required factor. Third, people with severe developmental disabilities should not be differentiated in comparison to people without disabilities, therefore, it was important to use nondiscriminatory designs. Accordingly, it was more efficient to modify and supplement clothing designed for non-disabled people with hidden functions to suit specific characteristics, rather than to develop specialized clothing. These demands were found to conform to what is referred to as a universal design concept, through which three nondiscriminatory shirt designs and two easy-to-use pants were designed.

This study defines the concept of the fashion meme, which has recently emerged as a fashion trend, influential fashion keyword. After analyzing the concepts and characteristics of traditional memes from prior studies, examples of fashion memes were collected from online community and social network services, while a literature study and case study analysis were conducted in parallel drawing on related articles and journals. Modern fashion memes refer to fashion-related symbols and fashion images that are spread online by word-of-mouth, together with fashion styles and items that spread as a result of being worn. Fashion memes in cyberspace are mainly spread through social network or message services, and sometimes combine text, images, videos, hashtags, and emoticons. Fashion memes are a type of collective action of the people in response to social problems in the world, and often involve humorous antics, satire, shock, and eccentricity. Shared fashion memes reflect the expression of personality expression and fun, and at the same time are used as an expression of designer and brand creativity and are integral to marketing. Fashion memes are classified into four types, based on two central axes as follows: non-commercial/ commercial and anti-fashion/fashion-friendly. Unlike traditional memes, Internet-based fashion memes emphasize elements of transformation through creativity as well as imitation, which has become a persisting contemporary trend beyond temporary phenomena.

The Nannophya species in Korea was thought to consist of only Nannophya pygmaea. Previous studies on the species, including life history and development, conservation and restoration, habitat characteristics, genetic studies, distribution, behavior, and taxonomy have been conducted. However, a new Nannophya species, Nannophya koreana, was recently discovered in Korea. Moreover, this new species was found to inhabit both Korea and Japan. Thus, the previous studies should be reevaluated in relation to the new species, Nannophya koreana, and the latter should be treated as an endangered species worldwide given the current population instability.

The purpose of this study is to create a shirt sloper suitable for an elderly male body shape by producing virtual models using a 3D-virtualization program, making a torso prototype using the Yuka CAD system, and employing 3D simulation to virtualize and calibrate the model. First, the following three types of obese dummies are implemented through the CLO 3D program: Type 1 exhibits body fat in the lower body; Type 2 exhibits an obese abdomen; and Type 3 displays a balanced form of obesity. Second, for the design of the shirt pattern, the waist back length (measured value+1), back armhole depth (C/10+12+3+0.5~1.5), front armhole depth (back armhole depth 0~1), front interscye (2C/10‒1+0.5‒0.5), armscye depth (C/10+2+3.5+ 0.5), back interscye (2C/10‒1+1), front chest C (C/4+2.5+1), back chest C (C/4+2.5‒1), front hem C (C/4+2.5+1(+2)), back hem C (C/4+2.5‒1(+2)), cap height (AH/3‒5), and biceps width (Front AH‒1, Back AH‒1) are calculated. Third, the virtual attachment of the shirt pattern is resolved by increasing the front and back armhole depths, and the front and rear wrinkles are improved by adding a back armhole dart. The front hem lift and lateral pull caused by the protrusion of the abdomen are amended by increasing the margin of the chest, waist C, and hip C, with the appearance improved by balanced margin distribution in the front, back, and side panels. The improved retail pattern with an increase in the front armholes C was balanced on the torso plate.

In this work, the correlation between the pore characteristics of activated carbon (AC) and the adsorption/desorption characteristics of evaporated fuel was studied. AC was prepared by various physical re-activation methods using coconut-derived commercial AC. Pore characteristics of the re-activated AC were investigated using N2/ 77 K adsorption isotherms. The structural characteristics of the AC were observed by X-ray diffraction and Raman spectroscopy. The butane working capacity was observed according to ASTM D5228. From the results, the specific surface area and total pore volume of the ACs were determined to be 1380–2040 m2/g and 0.60–0.96 cm3/g, respectively. It was also observed that various pore size distributions were found to be dependent on the functions of the activation method and time. A close relationship between butane activity/ retentivity and micropore/mesopore volumes was found. In addition, it was inferred that the volume fraction of micropores and sub-mesopores with diameters between 1.5 and 3.0 nm primarily controls butane activity.

해체 원전에서 총 폐기물의 약 70~80%에 해당하는 많은 양의 콘크리트 폐기물은 해체 폐기물의 대부분을 차지한다. 해체 시 발생된 콘크리트 폐기물은 핵종별 농도에 따라 규제해제 폐기물과 방사성폐기물로 정의할 수 있다. 따라서, 방사성 콘크리 트 폐기물의 처분 비용을 저감하기 위하여 자체 처분 및 제한적 재활용을 위한 제염 작업의 수행이 중요하다. 그러므로 콘크리트 폐기물의 효율적인 제염 작업을 위해 내부 방사능 분포를 예측하는 것이 필수적이다. 본 연구는 원전 해체 시, 발생되는 콘크리트 폐기물의 내부 방사능 분포를 예측하기 위하여 다양한 컴프턴 영상 재구성 방법의 성능을 비교하였다. 다양한 컴프턴 영상 재구성 방법으로 단순 역투사(SBP), 필터 후 역투사(FBP), 최대우도 기댓값 최대화 방법(MLEM), 그리고 기존 의 MLEM의 시스템 반응 함수에 에너지 정보가 결합되어 확률적으로 계산하는 최대우도 기댓값 최대화 방법(E-MLEM)이 사용되었다. 재구성된 영상을 획득한 후, 정량적인 분석 방법을 이용하여 재구성된 영상의 성능을 정량적으로 비교 및 평가하였다. MLEM 및 E-MLEM 영상 재구성 방법은 각각 재구성된 영상에서 높은 이미지 분해능과 신호 대 잡음비를 유지하는데 있어 가장 좋은 성능을 보여주었다. 본 연구에서 도출된 결과들은 원자력 시설 해체 시 방사성 콘크리트 폐기물의 내부 방사능 분포를 예측하기 위한 수단으로 컴프턴 영상을 사용할 수 있는 가능성을 보여주었다.

고준위방사성폐기물의 처분은 고심도 암반내에 처분시스템을 구축하는 심층 처분방법이 고려된다. 심층 처분은 처분용기, 완충재, 뒷채움재, 근계암반의 설계 요소인 공학적방벽과 천연 방벽으로 구성된다. 공학적방벽 중에서 벤토나이트 완충재는 암반으로부터 유입되는 지하수 흐름을 최소화하고 핵종 유출을 저지하는 기능을 한다. 지하수 유입으로 인한 완충재의 수리전도도 특성 규명은 처분장 공학적방벽의 안정성 및 건전성에 대한 성능 평가에 있어 중요한 사안이다. 본 연구에서는 경주 벤토나이트를 이용하여 다양한 건조밀도와 온도 조건에 따라 포화 수리전도도 실험을 수행하였으며, 120개의 실험 결과 를 다중 회귀 분석을 통해 수리전도도 추정 모델을 제시하였다. 실험 결과에서는 건조밀도가 커질수록 수리전도도가 감소하는 경향이 나타났다. 또한, 온도가 증가할수록 수리전도도가 증가하였다. 이러한 실험 결과들을 종합한 다중 회귀 분석 결과에서는 수리전도도 추정식의 결정계수(R2)가 0.93으로 높게 나타났다. 본 연구에서 제시된 수리전도도 추정식은 벤토나이트 완충재의 성능과 연관된 건조밀도와 온도의 영향을 고려하여 처분시스템의 공학적방벽 설계에 활용 될 것으로 판단된다.

Hepatic stellate cells (HSCs) play essential roles in normal and pathophysiological function in liver. In steady state, HSCs contribute to retinoid storage, immune tolerance, and extracellular matrix (ECM) homeostasis. Upon liver injury, they become activated and lead to morphological and functional changes. Studies have demonstrated that activation of HSCs by various stimuli such as toxins, microbial infection, or metabolic overload can promote the fibrotic changes in liver by production of ECM. Herein, we provide current knowledge about the basic characteristics of HSCs and the mechanism by which they are activated.

The following study analyzes the linguistic landscape of governmental public signs with focus on whether language rights are being fulfilled, in Garibong-Dong, Seoul, which has a high proportion of people with Chinese citizenship in Korea, most of whom are Korean-Chinese, utilizing “Language Rights of Linguistic Minorities: A Practical Guide for Implementation” (Izsák-Ndiaye, 2013) published by the UN OHCHR (Office of the High Commissioner for Human Rights) as a framework to see whether language rights are being fulfilled by governmental public signs. The study includes interviews with two workers of Korea Support Center for Foreign Workers about whether language rights of Garibong-dong's residents could be affected by the linguistic landscape and what efforts could the governments make for residents.
