Social media comprises a vast and consequential landscape that has been poorly mapped and understood. Hundreds of millions of people have eagerly moved many of the conversations and discussions that compose civil society into these services and platforms. There is a need to document and analyze these social spaces for many academic and commercial purposes. The Social Media Research Foundation has engaged a strategy to cultivate better research into the structure and dynamics of social media. The foundation is dedicated to the creation of open tools, open data, and open scholarship related to social media. It has implemented a free and open network collection, analysis, and visualization tool called NodeXL to facilitate social media network research. Using NodeXL a group of researchers has collectively authored a publicly available archive, called the NodeXL Graph Gallery, composed of network data sets and visualizations from users around the world. This site has enabled the aggregation of tens of thousands of network datasets and images. Use of the archive has led to scholarly research results that are based on the wide range and scope of social media data sets available.

This paper presents the test results of biological aerated filtration(BAF) process to replace activated sludge process by enhancing treated effluent quality and reducing the costs. In BAF process both BOD and SS compounds in wastewater are degraded and removed by biological reaction and filtration. Upflow BAF with expanded polypropylene media and downflow BAF with ceramic media were used to investigate the effects of hydraulic and organic loads on effluent quality. As a result, in BAF processes which has different media, upflow BAF reactor shows 5% higher efficiency than downflow BAF and this phenomena caused by backwashing methods and operational conditions. The results of influence factors analyzed by Factor Analysis Method in BOD and SS treatment efficiency are the size of media, hight of media bed and type of media. The quantitative effects of media size are 5.73% in TBOD, 5.78% in SBOD and 7.65% in TSS, so we confirmed the main factor is media size.

The purpose of this study is to examine the effects of university students' media sports immersion experience through social media on exercise immersion and exercise continuation. This research target was first selected as a population of university students who have contacted media sports aged 20 or older living in Gwangju Metropolitan City in 2019. The sampling procedure was divided into five parts: Dong-gu, Seo-gu, Nam-gu, Buk-gu, and Gwangsan-gu in Gwangju, and 300 men and women were sampled using cluster random sampling. After individually entering coded data into the computer, the statistical program (SPSS Windows.20.0 Version) was used. The results obtained through this research process are as follows. First, it was found that university students' immersion to media sports had a partial effect on their commitment to exercise. Second, it was found that university students' immersion in media sports had a partial effect on the continuation of the exercise. Third, it was found that college students' exercise commitment has a partial effect on exercise continuation.

지난 2021년, 국내 최초로 온라인 소비가 오프라인 소비를 뛰어넘을 정도로 언택트 경제가 급부상하였다. 덕분에 언택트 시장의 주도권을 가진 라이브 커머스는 무서운 속도로 성장하고 있고, 이는 적어도 2023년까지 이어질 것으로 예상된다. 중소기업은 물론 대기업, 심지어 개인까지 라이브 커머스 시장에 탑승한 현재, 라이브 커머스 시장의 경쟁력은 점차 사라지고 있다. 이로 인해 공급자들은 차별성을 두기 위해 여전히 다양한 방법을 찾아 시도하고 있다. 본 논문에서는 계속해서 수요되는 라이브 커머스 시장에서 경쟁력을 갖출 수 있는 방법으로 LED Wall의 활용을 제안한다.

코로나가 지속됨에 따라 많은 사람들이 언택트 생활 방식에 적응하고 있다. 기존 홈쇼핑과는 달리 실시간으로 상호 소통이 가능한 라이브 커머스가 등장하면서 쇼핑문화는 점차 발전하는 추세이다. 본 논문에서는 성장하는 라이브 커머스 시장에 맞춰 간편함을 갖춘 동시에 더 나은 품질의 방송을 제공하고자 4차 산업혁명의 산물인 '드론'을 접목하며 새로운 차원의 라이브 커머스 시스템을 구현하고자 한다.

시대가 변화됨에 따라 다양한 비대면 방송들이 증가하는 추세를 보이고 있다. 가상현실(VR)을 이용한 쇼케이스부터 실시간 쌍방향 소통을 활용한 무대까지 멀티뷰를 활용한 방송들이 여러 방향으로 활용되고 있으며. 이러한 환경 속에 관객과 조금 더 밀접한 방송을 진행하기 위한 여러 방법이 시도되고 있다. 따라서, 본 논문에서는 현장에서 녹화되고 있는 모든 카메라 소스들을 썸네일 사이즈로 만들어 한눈에 알아볼 수 있는 플랫폼을 구성하여 시청자가 원하는 카메라를 선택해 보고 싶은 장면을 선택할 수 있는 시스템을 제안한다.

The research want to know about form creation method's special quality that found in digital construction design process that using digital media, and they comparison analysis that who positive using digital media, Frank O. Gehry, Peter Eisenman, Greg Lynn, UN studio's work. First, In digital design process using digital media is make full use to design unfolding step and application way can change by architect's recognition difference of using digital media and each architect's design general idea unfolding process, and it means form creation process can change. Second, In digital design process a building form doesn't design adaptation to construction system, they directly design the third dimension form. So, they deduction a new form that unification and integration. Third, the architect that appear's in digital design process's part is existing, data from position of the master which it selects the coding selects the outcome goods which appears in computer operation with coordinator role of the originality and construction sense which it is visible.

This paper proposes a method for evaluating the work of manufacturing workers using MediaPipe as a risk factor for musculoskeletal diseases. Recently, musculoskeletal disorders (MSDs) caused by repeated working attitudes in industrial sites have emerged as one of the biggest problems in the industrial health field while increasing public interest. The Korea Occupational Safety and Health Agency presents tools such as NIOSH Lifting Equations (NIOSH), OWAS (Ovako Working-posture Analysis System), Rapid Upper Limb Assessment (RULA), and Rapid Entertainment Assessment (REBA) as ways to quantitatively calculate the risk of musculoskeletal diseases that can occur due to workers' repeated working attitudes. To compensate for these shortcomings, the system proposed in this study obtains the position of the joint by estimating the posture of the worker using the posture estimation learning model of MediaPipe. The position of the joint is calculated using inverse kinetics to obtain an angle and substitute it into the REBA equation to calculate the load level of the working posture. The calculated result was compared to the expert's image-based REBA evaluation result, and if there was a result with a large error, feedback was conducted with the expert again.

This research aims to obtain basic information on the present situation of the instructional media on clothing and textiles education, in middle and high schools. It also strives to get various information needed in order to improve educational environments and teaching methods. The targets of this survey were 225 teachers who teach home economics at middle and high schools in Taejeon, Choongchungnamdo and Junrabookdo. I made up questions their awareness about the instructional media on clothing and textiles education, the educational circumstances of their schools having to do with new media, and their real educational goal. Methods such 3s frequency, percentage, and Chi-square(${\chi}^2$)(statistical significance of differences between variables) were used to research the differences of awareness on using instructional media, according to teachers'various characters, were checked using the SPSS WIN computer program. The results of this research were as fellows; 1. They thought content on the management and the materials of clothing were the ones that need to be developed, compared to other content having to do with the curriculum on clothing and textile education. 2. The real things tuned out to be the molt useful and effective. So the most frequently used media was the Over Head Projector. Also, the teachers expressed in general that they wished to increase the use of computers in order to teach more efficiently. 3. We knew the teachers had little knowledge on the software developed for clothing and textiles education. The infrastructures for educating the using of clothing and textiles, using computers and the internet, were very poor in most schools. The new curriculum that has been proposed needs a more enlarged investment in order for it to function properly and effectively.
