Purpose: This study sought to identify the factors influencing learning motivation and demotivation in online dental technology students. Methods: A survey was conducted from October 1 to 30, 2021, on 188 dental technology students. The collected data were processed using the IBM SPSS IBM SPSS Statistics ver. 22.0 statistical program (IBM), and frequency, factor, and one-way ANOVA analyses were performed, for which the significance was set at 0.05. Results: It was found that the main online learning motivation factors were the usefulness of the learning content, interest, and confidence in the activities, the relationships with the teachers and friends, the feedback, and learning satisfaction. The factors that reduced the students' online learning motivation were interaction difficulties, maladaptation to the self-directed learning environment, the inadequate number of learning activities, and activity difficulty. Conclusion: Based on the identified online class motivation and demotivation factors, better systematic management and increased research are needed to improve the quality of non-face-to-face classes.

Guide robots that provide services in public places have recently emerged as a non-face-to-face solution with the spread of COVID-19 and are growing. However, most guide robots provide only the same level of intelligence and the same interaction in different and changing environments. Therefore, its usefulness is limited and customers' interest is quickly lost. To solve this problem, it is necessary to develop social intelligence that can improve the robot's environment and situational awareness performance, and to continuously maintain customer interest by providing personalized and situational services. In this study, we developed guide robot services based on social HRI components that provides multi-modal context-aware. We evaluated service usefulness by measuring user satisfaction and frequency of use of the service through the survey. We analyzed the service quality attributes to identify the differentiating factors of guide robot based on social HRI components.

The Publicly Purchased Property (PPP) Program since 2004 has allowed low-income households to reside in decent housing at a reasonable expense and to live in a community they choose. With an increasing number of the housing stock, management of the properties becomes a growing concern. The purpose of this research is to find out the satisfaction of the tenants with residential environment and housing management. To collect data, a face-to-face interview survey was conducted for 310 households living in the designated properties of 8 cities in and outside the Seoul Metropolitan Area (SMA). Most of the households were a family of three headed by late middle-aged man and lived in physically sound, small-sized units at an affordable cost. Overall satisfaction with living environment was higher in non-SMA than in SMA, and influenced by building deterioration and unit size. Further, most of the respondents were in favor of housing management services provided by a nearby public housing estate. Building deterioration and regular onsite visits of management staff were determinants in the satisfaction with housing management. The results indicate that proper housing management delays building deterioration and assures decent living for low-income people, leading to high levels of residential satisfaction.

The purpose of this study was to investigate the infiluence of positive and negative word-of-mouth informations on visiting intention of hairshop customers. Data were collected from 342 adult females and analyzed by using frequencies, factor analysis and regression utilizing SPSS/PC+. The results showed that positive word-of-mouth informations such as shop employees' skill/attitudes, physical benefit, comfortable facilities, time saving/consistent service, kindness and rational price had influence on the visiting intention of hairshop customers. The negative word-of-mouth informations that consumers had experienced using hairshop were categorized as untrustworthy face-to-face customer management, non-customer service oriented mind, and unskilled employees/inefficient hairshop environment. The negative word-of-mouth informations had no effect on the visiting intention.

Background: To investigate the mediating effect of learning flow in the relationship between blended learning achievement and learning satisfaction in dental hygiene students, and to identify whether face-to-face studies should be substituted with non-face-to-face studies. Methods: Total 134 dental hygiene students, who underwent blended learning in the dental hygiene class during the first semester of 2021, were recruited. The research tools were blended learning achievement, learning flow, and learning satisfaction, comprising 15 questions in total. Mediation regression analysis was used to analyze the mediating effect of learning flow in the relationship between learning achievement and learning satisfaction, and that between each variable. Results: Learning flow and learning satisfaction (r=0.490, p<0.001) were positively interrelated, and the interrelation between variables was statistically significant. Class environment had the biggest effect as a subfactor of class achievement, and it appeared to have an effect on class attitude and learning motive. The effect of learning flow on learning satisfaction was statistically significant. Learning flow was partially mediated by both blended learning achievement and learning satisfaction. Learning flow was directly related to blended learning satisfaction and learning achievement. Conclusion: The results showed the possible use of blended learning in dental hygiene theory and practical subjects.

글로벌 팬데믹으로 전 세계는 삶과 생존을 최우선의 가치로 방향성을 정립하고 디지털 기술을 활용한 새로운 패러다임을 만들어왔다. 언택트는 편리성의 가치를 넘어 방역과 위생 관점에서 필수적인 가치로 변하였고, 산업체 전반의 프로세스를 집체형에서 비대면으로 전환시켰다. 플랫폼은 가상공간에서 유기적인 커뮤니티를 형성하고, 기업은 실재감 기반의 새로운 서비스를 시작하였다. 현실과 유사한 환경 구축에 필요한 실재감을 위해 평면 이미지 중심의 2D에서 다면화된 3D로 정보는 표현, 저장되고 있다. 기업은 메타버스 플랫폼의 증강현실, 가상세계, 거울세계 등의 유형을 필두로 3D 모델링을 활용한 마케팅을 전개하고 있다. 이러한 변화의 시대 흐름에서 국내외 주얼리 브랜드 이커머스 환경의 3D 모델링 현황과 사례를 분석하고, 3D 모델링에 대한 주얼리 산업체의 활용 방안을 제시하는 데 본 연구의 목적이 있다.

This paper describes an approach to analyze geometrical information of building images for understanding outdoor environment of autonomous navigation robot. Line segments and color information are used to classily a building with the other objects such as sky, trees, and roads. The line segments and their two neighboring regions are extracted from detected edges in image. The model of line segment (MLS) consists of color information of neighbor regions. This model rules out the line segments of non-building face. A building face converges into dominant vanishing points (DVPs) which include one vertical point and one of five horizontal points in maximum. The intersection of vertical and horizontal lines creates a facet of building. The geometrical characteristics such as the center coordinates, area, aspect ratio and aligned coexistence are used for extracting the windows in the building facet. In experiments, 150 building faces and 1607 windows were detected from the database of outdoor environment. We found that this result shows 94.46% detection rate. These experimental images were all taken in Ulsan metropolitan city in Korea under difference of viewpoints, daytime, camera system and weather condition.

Although the Internet has been a important communication tool in modern societies, researchers did not pay attention to its' positive impacts on individual's psychological process. The Internet provides users with a unique environment such as visual isolation, non face-to-face communication, and easiness to escape from social influences. This environment enables people to take free action according to their personality and disclose themselves. From the uses and gratification perspective, the current research reveals that individuals with high extraversion are inclined to maintain social networking sites and those with high openness participate in web communities. The findings indicate that individuals' social use of the Internet may reflect their personality. To fill the research void like this, this study proposes a new research model in which well bing as well as perceived value are positively linked to satisfaction and continuance to use. The statistical results obtained by applying PLS to the valid 150 questionnaires showed that the well bing has stronger positive influence on satisfaction and continuance to use than the perceived value. Therefore, a practical implication is suggested that the web site need to be designed in a way of arousing users' well bing more strongly.
