Technology adoption has been an important issue for researchers and practitioners. In this paper, we identified the relationships between intention of technology adoption and technological affinity and other psychometric characteristics. We believe that technology affinity may be one of the general psychometric traits of individuals, and thus people have a different affinity levels which may influence the technology adoption intention. As a result it was found that need for cognition and self efficacy had positive influence on technology affinity, and the affinity also positively affected adoption intention. In addition, it was also found that technology affinity displayed a mediating role for the consumers adoption intention with need for cognition and self efficacy.

모바일 사용자의 주변 상태를 자동으로 인지하는 상황 인지 기술은 사람과 컴퓨터의 상호작용에 있어서 중요하다. 모바일 환경에서 사용자의 상황 인지를 하기 위해서는 플랫폼단에서 상황 정보를 수집하고 처리하는 미들웨어와 대량의 정보를 저장하고 분배해주는 서버가 필요하다. 특히 모바일 사용자간 친밀한 관계를 인지하기 위해서는 동시다발적으로 발생하는 상황 정보들을 효율적으로 처리하는 시스템이 필요하며 전체 성능에 영향을 적게 주어야 한다. 따라서 본 논문에서는 상황 인지 플랫폼에서 다양한 상황 정보들을 처리하는 액티비티 매니저 모듈을 구현한다. 제안하는 모듈은 상황 정보를 플랫폼간 통신이 가능한 형태로 변환하는 기술을 포함하며 상황 정보의 알림, 요청 작업을 실시간으로 처리하여 공유함으로써 사용자간 친밀한 관계를 분석할 수 있다.

Estimating levels of user trust is important for maintaining continuous use of e-commerce systems because trust alleviates user concerns about the invisibility of service providers or their reputation. Conventional trust estimation approaches such as policy-and reputationbased reasoning have focused on the experience of e-commerce systems at an early stage. However, only a few trust reasoning methods have considered the mature stage, which is more related to continuance intention. We propose a trust reasoning method dedicated to the mature stage of using e-commerce systems. In particular, a new method of unobtrusively estimating the degree of user intimacy is developed, because intimacy has been highly associated with trust as well as reputation. Our experiments show that the proposed method is valid and can be used in conjunction with reputation-based trust reasoning.

The COVID-19 pandemic highlighted the importance of remote education, yet the adoption rate of AI in the educational sector remains relatively low, and studies into learners' familiarity with using AI learning robots are scarce. In response, this study analyzes the factors influencing users' familiarity with AI learning robots in a smart learning environment tailored to the untact era. To this end, social big data analysis was used to examine changes in public perception and the frequency of mentions of smart learning and AI learning robots. The results showed that positive perceptions of smart learning significantly outweigh negative ones, reflecting the convenience and improved accessibility that technology brings to education. However, there is also a considerable negative perception attached to smartphone use, which is interpreted as reflecting concerns that smartphones may disrupt learning and bring other negative aspects of technology dependence. These results indicate mixed social concerns and expectations regarding the educational use of smart learning and AI technologies. The effective introduction and use of AI learning robots, especially in smart learning environments, necessitate considering these social perceptions. This study provides foundational data for the effective implementation and use of AI learning robots in smart learning environments and suggests the need for approaches that primarily consider users' familiarity and social perceptions in the development of educational technologies.

This study aimed to identify factors influencing depression in married middle-aged men. Subjects were 141 married middle-aged men (40~60 years) living in C and D city. Questionnaires included general characteristics, body mass index, marital intimacy, self-esteem, life event stress, and depression. Data were collected from August 15 to October 20, 2020. Collected data were analyzed by descriptive statistics, independent t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression using SPSS Win 23.0. As a results, depression had a significantly negative correlation with marital intimacy (r=-.44, p<.001) and self-esteem (β=-.40, p<.001). Self-esteem had a significantly positive correlation with marital intimacy (r=.48, p<.001). Factors influencing depression in marital middle-aged men were marital intimacy (β=-.24, p=.003) and self-esteem (β=-.40, p<.001). These variables explained 32.1% of depression. To reduce depression of married middle-aged men, nursing strategies considering marital intimacy and self-esteem must be provided to the middle-aged men.

During pregnancy, the woman experiences physical and psycho-social changes. Such changes and other factors may become stress for the pregnant woman, making it difficult to maintain healthy and happy pregnant period. In this study, we identify factors for the stress, marital intimacy, family support, and fatigue, in order to provide the foundation for developing intervention programs and improve the quality of nursing. The subjects of there search were 185 pregnant women. Stress had a negative correlation with marital intimacy and family support, and positive correlation with fatigue. Family support, fatigue, adjustment to change due to pregnant, and breastfeeding experience were the influencing factors on the stress of pregnant women. A stress management program for pregnant women needs to be designed to help them with their physical and psychological adjustments. The program will be more effective when accompanied by the family support.

본 연구에서는 유치원에서의 훈육과정을 관찰하고, 이에 대한 담론을 분석함으로써 교사와 학생간의 관계 형성 과정 및 유형에 대해 살펴보았다. 이를 위해 미국에 위치한 대학부속 유치원에 재학중인 만 4세 학생 32명과 지도교사와의 대화 내용을 녹음하였으며, 지도교사와의 심층면접도 실시하였다. 분석 결과, 교사-아동간의 관계 형성 유형은 크게 친밀, 독립, 갈등적 관계의 세 유형으로 구분되었으며, 대부분의 아동들은 교사와 친밀 또는 독립적 관계를 보였다. 단지 3명의 학생이 교사와의 갈등적 관계를 보였는데, 이는 교사의 차별적 처사 때문이 아니라 교사가 긍정적인 상호작용을 시도했음에도 불구하고 학생들이 교사의 암시적인 단서를 놓치거나 무시함에 따라 부정적 상호작용이 반복되면서 발생되는 것으로 밝혀졌다. 즉 학생들의 미성숙한 사회적 기술로 인한 것이었다. 따라서 본 연구에서는 교사가 학생과의 갈등적 관계 형성 과정을 인지하고, 그들을 위해 명시적인 훈육방법을 제공해야할 필요성에 대해 제안하였다.

South Korea faces elderly care crisis with both low fertility rate and rapid ageing rate. Long-term care insurance in 2008 has taken care burden from family to nation. However, few options, lack of tailored services, and unstable community care plan caused blankness of care in some areas. Especially, increasing dementia rate has become an emergent social issue. Welfare technology could be a useful alternative to fill out the gap between demand and supply. Using FGI method on two groups(high-risk dementia group and MCI group), intimacy, accessibility and preventive way of dementia with welfare technology are analysed in this paper. Despites of a few differences of dementia progress, interests towards technology are expressed. More suggestions using TV and normal telephone to improve daily independence are presented as well. Amongst MCI group, help-service for technology-use at ADS and linkage ways of in-home services are also suggested.

Mobile industry has been progressed rapidly with new mobile technique develpment. The mobile is a communication device for the young generation and give great additional images through animations and characters. It is expected that the mobile industry would elevate greatly in means of the animation characters that is connected directly, closely, and amicably to the sense of humane beings. Of those animations, 3D animation is a high communication technique that rinks to directly the expression of person in way of a sense of space, three dimension, and reality. Surely the new 3D animation will be developed constantly and in various way. It is consideralbe that the manufacture of 3D mobile animation links closely to cartoon that forms concerns of people.

With the growth of information technology, people consume online video contents via mobile phone without time and location constraints. Drawing upon uses and gratification theory, this study examines the effects of usage motives and affinity on user activities on YouTube. Specifically, user activities are subdivided into pre-viewing and during-viewing activities in this study. Results show that convenient entertainment and social interaction are the significant indicators for pre-viewing activities, whereas five different motives significantly influence during-viewing activities. Furthermore, affinity is the significant determinant of the both activities. The theoretical and practical implications are also discussed.
