In order to examine the cultural vicious cycle of gender representation in online educational content, this paper reviewed the top five popular webtoons of inamootoon (EBStoon), Korea's first children's webtoon platform. The patterns of appearance representation that distinguish character's gender, the desire and psychology of characters according to gender, and their functions in the work were critically analyzed from a feminist perspective. In most of the works, the appearance of characters often follows gender stereotypes. It appears that women have long hair and wear dresses while men have short hair. On the other hand, the gender characteristics in terms of psychology and function show the aspect of breaking gender's cliche. The gender proportion of the protagonists is almost the same. Regardless of gender, they function as solvers or rescuers, bravely and wisely overcoming the problem situation. By the way, it is interesting that in representing the main character's gender, the weaker the gender stereotypes, the more popular the work among the readers. This fact suggests that the critical acceptance and choice of young readers can break the cultural vicious cycle of gender representation.

The purpose of this study is to find out consumers' perceptions of "metaverse," a newly spotlighted technology, through big data analysis as a non-face-to-face society continues after the outbreak of COVID-19. This study conducted a big data analysis using text mining to analyze consumers' perceptions of metaverse before and after COVID-19. The top 30 keywords were extracted through word purification, and visualization was performed through network analysis and concor analysis between each keyword based on this. As a result of the analysis, it was confirmed that the non-face-to-face society continued and metaverse emerged as a trend. Previously, metaverse was focused on textual data such as SNS as a part of life logging, but after that, it began to pay attention to virtual reality space, creating many platforms and expanding industries. The limitation of this study is that since data was collected through the search frequency of portal sites, anonymity was guaranteed, so demographic characteristics were not reflected when data was collected.

As the world becomes an aging society due to a decrease in the birth rate and an increase in life expectancy, a system for health management of the elderly population is needed. Among them, various studies on occupancy and activity types are being conducted for smart home care services for indoor health management. In this paper, we propose a random forest model that classifies activity type as well as occupancy status through indoor temperature and humidity, CO2, fine dust values and UWB radar positioning for smart home care service. The experiment measures indoor environment and occupant positioning data at 2-second intervals using three sensors that measure indoor temperature and humidity, CO2, and fine dust and two UWB radars. The measured data is divided into 80% training set data and 20% test set data after correcting outliers and missing values, and the random forest model is applied to evaluate the list of important variables, accuracy, sensitivity, and specificity.

Korean medical device industry has laid the foundation for full-fledged growth and development with the G7 medical engineering technology development project that started in 1995, and the medical device production in 2020 increased by 8.52 times and the export by 13.94 times, compared to those in 2001. In early years, electronic medical devices such as ultrasound imaging device contributed greatly to Korean medical industry, but top ranks in medical device production and export in Korea has shifted recently to in vitro diagnostic medical devices and dental implants. However, the share of imported medical devices in the Korean medical device market have not changed much; it still ranges in 60 to 70%, as the Korean medical device industry produces and exports mid- to low-priced medical devices, and technology-intensive and capital-intensive high-priced medical devices are mainly imported. In this paper, we compare the leading medical devices produced by major Korean companies and those by global top medical device companies to suggest strategies for the Korean medical device companies to enter the global market.

This study explored the lexical sophistication features to distinguish the group membership of English proficiency, using the automatic analysis program of lexical sophistication. A total of 600 essays written by 300 Korean college students were extracted from the ICNALE (International Corpus Network of Asian Learners of English) corpus and a discriminant function analysis was performed using SPSS program. Results showed that the lexical features to distinguish three groups of English proficiency are SUBTLEXUS frequency content words, age of acquisition content words, lexical decision mean reaction time function words, and hypernymy verbs. High-level Korean students used frequent content words from SUBTLEXUS corpus to a lesser degree and produced more sophisticated words that can be learned at a later age and take longer reaction time in lexical decision task, and more concrete verbs.

This research presents the actual situation analysis and suggestions for the changes, experiences, and process of adaptation that college students have experienced throughout their studies and life over the past two years and more. In-depth interviews were conducted with university students, who are educational objects, and qualitative analysis methods were used to explore the overall living experiences under the pandemic situation. The interview questions were composed to cover classes, life, and emotional experiences after COVID-19, and the result of analyzing the responses boiled down to four super-categories of 'adaptation process to a new system, daily incontinence, struggle for health, and longing for connection.' This study is significant in that it analyzed the experiences and intimate changes of individual college students in unexpected and challenging situations, and urged the myriad aspects that universities, society, and the government should illuminate and respond to.

A large number of motors and sensors are used to drive a humanoid robot. In order to solve the wiring problem that occurs when connecting multiple actuators, a controller based on a communication network has been used, and CAN, which is advantageous in terms of cost and a highly reliable communication protocol, was mainly used. In terms of the structure of the controller, a torque control type structure that is easy to implement an advanced algorithm into the upper controller is preferred. In this case, the low communication bandwidth of CAN becomes a problem, and in order to obtain sufficient communication bandwidth, a communication network is configured by separating into a plurality of CAN networks. In this study, a stability analysis on transmission time delay is performed for a multi-motor control system in which high-speed FlexRay and low-speed CAN communication networks are hierarchically connected in order to obtain a high communication bandwidth, and sensor information and driving signals are delivered within the allowed transmission time. The proposed hierarchical network-based control system is expected to improve control performance because it can implement multiple motor control systems with a single network.

지식표현은 일반적으로 논리, 규칙, 프레임 또는 의미망 형태로 표현되며, 최근에는 의미망을 이용한 온톨로지 형태로 표현되고 있다. 이러한 지식표현 방법은 개념을 설명하는 문맥적인 정보나 개념들 간의 구조적인 정보를 이용하여 개념에 대한 지식을 논리적으로 표현하는데 중점을 두었다. 하지만, 지식표현에 사용되는 의미정보는 사람에 의해 수집되고 정제되기 때문에 많은 시간, 비용 및 인력이 필요하다는 한계가 있고, 새로운 의미를 추가하거나 기존의 의미를 수정하는 것이 매우 어렵다는 한계가 있다. 색채는 특정 대상이나 개념에 대한 의미, 연상, 상징 등 객관적인 특징 뿐 아니라 시대, 나라, 문화와 같은 사회적 배경을 반영하기 때문에, 정보를 제공하고 감성을 전달하는 효과적인 수단으로 사용되고 있다. 이에 본 논문은, 색채를 이용한 의미정보모델 구축을 위해, 색채정보를 수집하고 정량적으로 분석하는 방법을 제안한다. 긍정/부정/불안/중립으로 구성된 감성어휘 273개를 이용하여 이미지를 수집한 결과 총 130,944개의 이미지를 수집하였다. 이미지에는 여러 가지 사물, 행동, 배경, 색채 등 다양한 정보가 혼재되어 있어 감성어휘와 연관된 색채를 구별하기 어렵기 때문에 이미지를 직관적으로 설명할 수 있는 사용자 태그를 별도로 수집하였다. 태그는 총 2,836,395개를 수집하였고 각 이미지와 그룹에서의 가중치를 구하였다. 태그의 가중치를 통해 이미지가 그룹 내에서 갖는 중요도를 판별하였고, 각 그룹 별로 상위 30%의 이미지를 추출하여 대표 색채를 분석하였다.

A hierarchy is defined as a system wherein its parts are interconnected with one another and the lower levels are constrained by the higher levels to various degrees, depending on the time constraints of the behavior. We illustrate that the concept of hierarchy is identified in the Baekdoodaegan frame, and that the Korean national area was hierarchically divided into many watersheds in many old maps. The Baekdoodaegan and Jeongmack were consistent with the hierarchy of climatic as well as spatial variables. It is evident from an old map that the concept was coined as early as in 1402. A typical configuration of Korean landscape, which was developed in the arrangement of village and surrounding landscape elements situated in a watershed, may be associated with the hierarchical approach to land and culture. Although current practices based on the concept are meaningful, further diverse studies are needed to improve ideas.
