One of the most significant changes is the paradigm shift from teacher-centered learning to learner-centered learning. Along with this paradigm shift, understanding of characteristics of e-learners who are both system users and learners is needed. Before suggesting a comprehensive framework, this study proposes research model that can improve a learning performance using the flow theory. The results show that intrinsic interest and focused attention are significant predictors of learning performance. Especially, intrinsic interest is more important on learning performance than focused attention. Information quality and skill are found to be strong predictors of the intrinsic interest. Also, perceived ease of use, skill and computer self-efficacy are strong predictors of the focused attention.

The effectiveness of behavior group counseling using the games of children with Attention Deficit Hyperactivity Disorder(ADHD) was studied with 24 primary school children (12 each in the experimental and in the control groups). The subjects were selected on the basis of the Abbreviated Conners Teacher Rating Scale-Revised. The counseling program consisted of 12 sessions over a 6-week period. Effectiveness of the training was evaluated with the Conners Teacher Rating Scale-Revised, the ADHD teacher's rating scale, and the Korea-Child Behavior Checklist. Findings were that the group receiving counseling exhibited improved attention, social relationships, and self control. They also exhibited decreased carelessness-passivity, hyperactivity, hostility and fewer behavior problems.

관계 추출은 주어진 문장이나 문서에 존재하는 개체들 간의 의미적 관계를 찾아내는 작업을 말한다. 최근 문서 수준 관계 추출 말뭉치인 DocRED가 공개되면서 문서 수준 관계 추출에 대한 연구가 활발히 진행되고 있다. 또한 사전 학습된 Masked Language Model(MLM)이 자연어처리 분야 전체에 영향력을 보이면서 관계 추출에서도 MLM을 사용하는 연구가 진행되고 있다. 그러나 문서 수준의 관계 추출은 문서의 단위가 길기 때문에 Self-attention을 기반으로 하는 MLM을 사용하면 모델의 계산량이 증가하는 문제가 있다. 본 논문은 이 점을 보완하기 위해 관계 추출에 필요한 문장을 선별하는 간단한 전처리 방법을 제안한다. 또한 문서의 길이에 상관없이 관계 추출에 필요한 어휘 정보를 자동으로 습득 할 수 있는 Relation-Context Co-attention 방법을 제안한다. 제안 모델은 DocRED 말뭉치에서 Dev F1 62.01%, Test F1 59.90%로 높은 성능을 보였다.

While Facebook and Twitter get worldwide attention, these popular SNSs are not available in China. As the leading local SNS, Sina Weibo has garnered much of the attention in China. The purpose of the study was to explore why Chinese college students use Sina Weibo and if gender differences exist in the motivations for using it. The results from a survey of 360 respondents show that Chinese students used Sina Weibo mainly for information-gathering, followed by accessibility to celebrity, social connection, self-presentation and entertainment. Among them the most dominant reason for using Sina Weibo was found to be information-gathering. This finding suggests that Sina Weibo functions as a platform to search for information on social issues and interests. The study also found that these motivations were significantly different between male and female users. Interestingly, female respondents used Sina Weibo much more broadly than male counterparts, accessing it to satisfy all needs such as information gathering, accessibility to celebrity, social connection, self-presentation and entertainment. Based on these findings limitations and direction for future studies are discussed.

Recently, Transformer has made great progress in video retrieval tasks due to its high representation capability. For the structure of a Transformer, the cascaded self-attention modules are capable of capturing long-distance feature dependencies. However, the local feature details are likely to have deteriorated. In addition, increasing the depth of the structure is likely to produce learning bias in the learned features. In this paper, an improved Transformer structure named TransDCS (Transformer with Dynamic Convolution and Shortcut) is proposed. A Multi-head Conv-Self-Attention module is introduced to model the local dependencies and improve the efficiency of local features extraction. Meanwhile, the augmented shortcuts module based on a dual identity matrix is applied to enhance the conduction of input features, and mitigate the learning bias. The proposed model is tested on MSRVTT, LSMDC and Activity-Net benchmarks, and it surpasses all previous solutions for the video-text retrieval task. For example, on the LSMDC benchmark, a gain of about 2.3% MdR and 6.1% MnR is obtained over recently proposed multimodal-based methods.

This study was undertaken to explore the relationship between the personality characteristic (the self-esteem) and tao clothing behaviors according to the sex and the five environmental variables. This study was designed with the hypothetic model regarding the age and the five environmental variables as Independent Variable, the self-esteem as Intervening Variable, the eight clothing behaviors as Dependent Variable. For the testing hypothesis, the questionnaries were adminstered to 335 high school boys and 308 high school girls in Pusan. The data was analyzed statistically at the B.N.U. Computer Center using to the Path Analysis (by Multiple Regression Analysis Method). The results were as follows : 1. There was significant difference in the self-esteem according to the sex. Boys had higher scores than girls. 2. There was no significant relationship between the self-esteem and all the environmental variables of this study. 3. There were significant differences in the clothing behavior subscales according to the sex. Girls had higher scores than boys in every clothing behavior subscales. 4. There were partial relationship between the clothing behavior subscales and the environmental variables. 5. There was a highly significant relationship between the self-esteem and the clothing behavior subscales except Comfort and Modesty. A negative significant aubscale were Interest, Psychological Dependence, Social Approval and Special Attention. 6. There were positively significant relationship among the clothing behavior subscales except Modesty-Aesthetics, Modesty-Interest, Modesty-Psychological Dependence and Modesty-special Attention.

Objectives : This study examined maternal object relations, child's and mother's perception on rearing attitude, and children's self-esteem in children with attention-deficit hyperactivity disorder (ADHD) and their mothers. Methods : 64 children with ADHD and their mothers were included in the study group. In the control group, there were 85 children and their mothers. Mothers completed the following tests : Bell object relation inventory (BORI), maternal behavior research instrument (MBRI), Beck Depression Inventory (BDI), and Korean ADHD Rating Scale (K-ARS). Children completed Children's Report of Parental Behavior Inventory (CRPBI) and Rosenberg self-esteem scale. Results : Mothers of ADHD children displayed more rejecting and controlling parenting style than mothers in the control group. ADHD children showed lower self-esteem and perceived their parents as not affectionate, but rejecting and controlling. Mothers with ADHD children who belonged to object relations pathological group showed more rejecting rearing attitude and their children believed that they were more controlling, compared with children and mothers in other conditions. Among factors in mother's object relations, insecure attachment and ego-centricity impacted the rearing attitude. In turn, affective rearing attitude mainly influenced children's self-esteem. Conclusion : This study suggests that the approach focused on mother's object relations may help with the treatment of children with ADHD.

The purpose of this study is to examine the relationship between job-seeking stress and somatization symptoms and to explore the mediating effects of maladaptive self-focused and emotional dysregulation in college students. The SPSS 21.0 and AMOS 21.0 were performed to analyze the path relationship between variables. First, maladaptive self-focused mediated the relationship between job-seeking stress and somatization symptoms. Emotional dysregulation mediated the relationship between job-seeking stress and somatization symptoms. Second, maladaptive self-focused and emotional dysregulation partial dual mediated the relationship between job-seeking stress and somatization symptoms. It suggests that college students with job-seeking stress tend to be maladaptive self-focused, therefore they have difficulty in emotion regulation and eventually expose somatization symptoms.

This study purposed to examine the effects of the Feuerstein's cognitive mediated learning for gifted children on attention control and attention shift. For the study, 40 gifted students were chosen from the 3rd graders in elementary schools and divided into test and control groups using K-WISC-III and Torrance Tests of Creative Thinking. The mediated learning program that is targeted to improve the executive functions of gifted children has used the tools of Organization of Dots, Analytic Perception and Comparisons among Feuerstein's Instrumental Enrichment(FIE). According to the results of this study, a significant improvement has been observed in selective attention, self-control, sustained attention, and attention shift through cognitive mediated learning. Therefore, it has been proven that the cognitive mediated learning is effective in reducing gifted children's problematic behaviors that are caused by a lack of attention control and attention shift and improving their cognitive functions and potentials.
