The purpose of this study is to investigate the influence of perceived parental attachment and self-differentiation on the adjustment to college life For this study, we used research data about the adjustment to college life, perceived parental attachment and self-differentiation which were collected from 271 university students live in Busan. We carried out correlation analysis to see the relationship between perceived parental attachment, self-differentiation and the adjustment to college life. Also, we carried out stepwise multiple regression to predict the most influential variable in college life. Results of this study were as follows. First, perceived parental attachment, and self-differentiation have a meaningful positive relationship with college life. Second, attachment anxiety, attachment avoidance, family projection, and cognitive and emotional functioning have more effects on the adjustment to college. Especially attachment avoidance affects college life more than others. These results show the importance of a wide variety of policy research to develope peer support program and counseling for a better school life on schools, classes, counseling centers.

Along with the transformation of the knowledge-based environment, e-learning has become a main teaching and learning method, prompting various research efforts to be conducted in this field. One major research area in e-learning involves adaptive learning systems that provide personalized learning content according to each learner's characteristics by taking into consideration a variety of learning circumstances. Active research on ontology-based adaptive learning systems has recently been conducted to provide more efficient and adaptive learning content. In this paper, we design and propose an adaptive learning system based on the concept lattice of Formal Concept Analysis (FCA) with the same objectives as those of ontology approaches. However, we are in pursuit of a system that is suitable for learning of specific domains and one that allows users to more freely and easily build their own adaptive learning systems. The proposed system automatically classifies the learning objects and concepts of an evolved domain in the structure of a concept lattice based on the relationships between the objects and concepts. In addition, the system adaptively constructs and presents the learning structure of the concept lattice according to each student's level of knowledge, learning style, learning preference and the learning state of each concept.

The purpose of this study was to investigate college life adaptation and loneliness of non-traditional adult learners with nursing major. A cross-sectional survey was conducted on one hundred and ten participants from selected universities in G city. A structured questionnaire which included general characteristics, a College Life Adaptation Scale and a Revised UCLA Loneliness Scale was a study instrument. Descriptive statistics, independent t-test, one-way ANOVA, and Pearson correlation coefficients were used for data analysis. The average level of college life adaptation was 44.8, while the score for loneliness was found to be 40.3. There was a significant difference in college life adaptation according to perceived health status. Loneliness showed a significant difference according to grades. A significant positive correlation was observed between college life adaptation and loneliness. In other words, the greater the loneliness, the lower the adaptation to college life. Thus, the results suggest that Korean universities should pay close attention to psychological factors such as loneliness to improve the adaptation of non-traditional adult learners with varied backgrounds to college.

This study aimed to analyze the relationships among the middle-aged women's gender role conflict, resilience, and psychological well-being, and to examine the mediating model of resilience on gender role conflict and psychological well-being. Data were collected from July 28 to August 5, 2021 for 302 middle-aged women aged 40-65 years. The Gender Role Conflict Scale specialized for middle-aged Korean women, internal traits subscale of Ahn's Resilience Scales, and Ryff's Psychological Well-being Scale were used for this study. PROCESS Macro 3.5 Model 4 was used to analyze the mediating effect. Results revealed that the middle-aged women's gender role conflict was negatively correlated with resilience and psychological well-being. And, the middle-aged women's resilience was positively correlated with psychological well-being. Because both the direct effect of the middle-aged women's gender role conflict on psychological well-being and its indirect effect through resilience were statistically significant, it was found that the middle-aged women's resilience was partially mediating their gender role conflict and psychological well-being.

With the growth of the Internet, multimedia streaming becomes an important means to deliver video contents over the Internet and the amount of the streaming multimedia contents is also getting increased. However, it becomes difficult to guarantee the quality of service in real-time over the IP network environment with instantaneously varying bandwidth. In this paper, we propose an optimal adaptation framework for streaming contents over the Internet in the sense that the perceptual quality of the multi-angie content with multiple visual objects is maximized given the constraints such as available bandwidth and transcoding cost. In the multi-angle video service framework, the user can select his/her preferred alternate views among the given multiple video streams captured at different view angles for a same event. This enhanced experience often entails streaming problems in real-time over the network, such as instantaneous bandwidth changes in the Internet. In order to cope with this problem, we assume that multi-angle video contents are encoded at different bitrates and the appropriate video streams are then selected or transcoded for delivery to meet such bandwidth constraints. For the user selective consumption of the various bitstreams in the multi-angle video service, the bitstream in each angle can be encoded in various bitrate, and the user can select a sub-bitrstream in the given bitrstreams or transcode the corresponding content in order to deliver the optimally adapted video contents to the instantaneously changing network condition. Therefore, we define the transcoding cost which means the time taken for transcoding the video stream and formulate a unified optimization framework which maximizes the perceptual quality of the multiple video objects in the given constraints such as the transcoding cost and the network bandwidth. Finally, we present plenty of the experimental results to show the effectiveness of the proposed method.

본 논문에서는 다양한 환경에서 사용자의 각기 다른 사용 상황을 인지하고 그에 맞는 콘텐츠 및 사용자 인터페이스를 실시간으로 구성하여 제공하는 방법에 대해 제안한다. 방송/통신 환경에서도 다양한 사용자가 다매체, 다채널 등 여러 방법으로 컨텐츠를 소비 하고 있기에 단말 환경 및 사용자 특성을 인지하여 그에 적응적인 콘텐츠와 사용자 인터페이스를 제공하는 사용자 반응형 서비스에 대한 논의가 계속 되고 있다. 또한 다양한 디바이스가 보편적으로 보급됨에 따라 사용자는 하나의 스크린에 모든 관심을 주는 것이 아니라 다양한 스크린으로 동시에 관심을 분산시킨다. 그 동안 사용자가 선호하는 콘텐츠가 제공될 경우 더욱 그 주목도를 높이기에 다양한 세컨 디바이스에 개인 적응적 사용자 인터페이스 및 컨텐츠를 제공하는 것이 서비스 차별화의 중요한 요소로 작용하고 있다. 제안하는 프레임워크는 다양한 세컨 디바이스 사용자가 IPTV 와 같은 VOD 서비스를 동시에 이용할 경우 개인화 디바이스를 통해 각자의 서로 다른 환경에 적응적인 부가 서비스를 제공 받는 서비스에 적용하여 테스트를 진행하였다.
