As the number of elderly people living alone increases, the frequency of fall accidents is also increasing. Falls are a threat to the health of older adults and can reduce their ability to remain independent. To solve this problem, we need real-time technology to recognize and respond to the critical condition of the elderly living alone. Therefore, this paper proposes a modified fall detection algorithm based on YOLO-KCF that can check one of the emergency situations in real time for the elderly living alone. YOLO can detect not only the detection of objects, but also the behavior of objects, namely stand and fall. Therefore, this paper can detect fall using the ratio of change of boundary box between stand and falling situation, and this algorithm can improve the shortcomings of KCF.

In this paper, we propose an intelligent model lot extraction of the web user's preference and present the results of evaluation. For this purpose, we analyze shortcomings of current information retrieval engine being used and reflect preference weights on learner. As it doesn't depend on frequency of each word but intelligently learns patterns of user behavior, the mechanism Provides the appropriate set of results about user's questions. Then, we propose the concept of preference trend and its considerations and present an algorithm for extracting preference with examples. Also, we design an intelligent model for extraction of behavior patterns and propose HTML index and process of intelligent learning for preference decision. Finally, we validate the proposed model by comparing estimated results(after applying the Preference) of document ranking measurement.

Methods: A cross-sectional survey was conducted from September 11 through October 1, 2020, involving a total of 235 third and fourth year of nursing students enrolled in two universities in U and K city. Self-report questionnaires consisting of demographic characteristics, knowledge, attitudes and infection prevention behaviors toward the COVID-19 were administered to the participants. Results: Influencing factors for infection prevention behaviors were gender (β=0.21, p<.001), attitudes toward infection control (β=0.38, p<.001), education experience regarding COVID-19 (β=0.21, p=.004), and a visit to the hospitals or the areas where the COVID-19 case has occurred or been admitted (β=-0.18, p=.003) which explained 23.6% of the total variance. Conclusion: The results of this study provides basic information regarding nursing students' knowledge about COVID-19, attitudes toward infection control, and infection prevention behaviors during the initial outbreak of COVID-19.

일반적으로 컴퓨터를 이용한 디자인 지원 시스템은 다지이너의 행동과 같은 데이터를 통계적으로 분석하여 일련의 디자인 행위를 추출해 내는 인공지능의 접근 방식을 사용하여 왔다. 그러나 이는 많은 양의 수집된 데이터를 기반한 방법이기 때문에 계속해서 변화하는 유행에 대처할 수 없을 뿐만 아니라 개인의 취향을 반영하기도 어렵다. 이같은 문제점을 해결하기 위해 이 논문에서는 대화형 유전자 알고리즘(Interactive Genetic Algorithm : IGA)을 이용하여 명시적으로 표현하기 어려운 취향을 적절히 반영하는 디자인 지원 시스템을 제안한다. IGA는 상호작용에서 얻어지는 사용자의 평가를 적합도 함수로 사용하는 유전자 알고리즘의 하나로, 일반적인 적합도 함수를 결정하기 어려운 디자인이나 예술 등의 문제 해결에 사용될 수 있다. 한편, 몇 개의 부분적인 곡선으로 의상의 디자인을 표현하였던 기존의 방법들과는 달리 전체 디자인을 목과 몸통, 팔과 소매, 치마와 허리선의 세 가지 부분 디자인으로 나누어 표현함으로써 좀더 현실적인 여성복을 디자인할 수 있었다. 시스템의 인터페이스를 보완하기 위해 OpenGL을 이용한 3차원 모델이 사용되었으며, 사용자들을 대상으로 한 실험 결과 제안한 의상 디자인 지원 시스템이 효과적임을 알 수 있었다.

The research was conducted with awareness of cultural uniqueness in each country and similarities and universality among countries. On that account, it raised questions about the idea that social well-being can be achieved only materialistic consumption and its cultural symbolism can lead to incongruity in social hierarchy and then dysfunctions in a counter way. On the other hand, the value of well-being can be achieved by many different ways and within one's limited budget as well as material consumption. This paper provides basic information about the development of essential wellbeing products and strategies for building market segmentation in the industry. The research also provides policy makers with the direction of welfare policy in our society to establish a foundation of creating conditions for true well being. This paper will be helpful in fulfilling well-being in our whole society.
