  • The purpose of this study is to suggest that the movement expression activity of intellectually disabled people is effective in the learning process of LMA motion recognition based on Kinect sensor. We performed an ICT motion recognition games for intellectually disabled based on movement learning of LMA. The characteristics of the movement through Laban's LMA include the change of time in which movement occurs through the human body that recognizes space and the tension or relaxation of emotion expression. The design and implementation of the motion recognition model will be described, and the possibility of using the proposed motion recognition model is verified through a simple experiment. As a result of the experiment, 24 movement expression activities conducted through 10 learning sessions of 5 participants showed a concordance rate of 53.4% or more of the total average. Learning motion games that appear in response to changes in motion had a good effect on positive learning emotions. As a result of study, learning motion games that appear in response to changes in motion had a good effect on positive learning emotions

  • Ecosystems of the southwestern tidal flats in Korean peninsula have been seriously injured by human activities. The results are mainly due to the lack of public recognition and education on tidal flats. In particular, thoughtless visitors in tidal flats are giving rise up damages because of non-systematic experience programs to tidal flat ecosystems. Therefore, experience programs friendly to natural tidal flats are necessary as a plan to reserve tidal flats and to enhance the effects of environment education on the flats. Experience learning programs on tidal flats can divide into direct experience, indirect experience and local society works. Direct experience work must undergo tidal flats directly and consider on forming the flats with natural refinement functions. Indirect experience includes deeper knowledge on role, circumstance and ecosystems of the flats on the bases of direct experience on the flats. In addition, local society learning must have the feeling and understanding on socio-cultural characteristics of local society itself through above two works. Experience activity would be a kind of injuring one to tidal flats. However, appropriately planned experience and education works on tidal flats could be sustainable development to attract desirable human activity on coastal ecosystems.

  • While the endeavor to introduce the service activity in the college education is enlarged, the object of this study is to introduce the concept of service learning in social work education. The 'content centered service-learning' is focusing on the practical education, the liaison and participation in community and the promotion of civil awareness which are very important in social work education that focuses on the interest and participation in the human and social problem as practical study. This study contemplates the educational effect of the course of social work combined with service learning. This study verifies the self-efficacy, the altruism, the change of social responsibility of students and the effect by carrying out the course of social welfare and service activities side by side. To evaluate the effect of service learning, pre and post test and qualitative analysis in journal of service activity, the discussion during the class and the mid and final term evaluation were done. Through the service learning, students showed the promotion in self-esteem, the altruism, the social responsibility, the self insights as a social worker and were able to have the chance to consider their future job. From the view point of local centers, it was evaluated that the service activity of students was helpful to the institutions and the clients, and that the liaison between the community agency and the college and the experience of integration of service learning and the course of social welfare was helpful too. Based on the above mentioned results, this study provide some recommendations in implementation of service-learning as the teaching methodology of social work.

  • This study conducts statistical analysis based on a survey of 300 CEOs from Korean companies in order to examine the effects of a CEO's internal?external activities (information, knowledge management, learning organization) on business innovation activity (exploitative, exploratory) and business performance. Analysis results show that learning organization activity had a significant positive (+) effect on exploitative and exploratory innovation activity. In addition, knowledge management activity lacked statistically significant effects on exploratory innovation activity. Furthermore, exploitative and exploratory innovation activity was affected by CEO's internal?external activities (information, knowledge management, learning organization) and had a significant positive (+) effect on company's business performance. but it was shown that the level of influence was different. Results of this study imply that maximizing business performance through developing innovation activity by CEO's internal?external activities (information, knowledge management, learning organization) in the company, extracting activity advantageous to company's business environment based on activity perceived in the precedent study and business strategy becomes advantageous to the attainment of business performance objectives.

  • 1. Objectives This study was purposed to find Dong's thoughts about the eight items of the "The Great Learning(Ta hsueh)" 2. Methods It was researched through comparative and overall study on the Dong-mu's thoughts in "Gyukchigo(格致藁)" 3. Results (1) Dongmu reinterpreted the eight items of the "The Great Learning(Ta hsueh)" as the relations between the subject and the object from the ontologic assumption of Affairs Mind Body Objects as the principle of existence and correlation, summarized into four categories, and classified into the individual and subjective affairs, and the universal and objective affairs. The four categories of the eight items of the "The Great Learning(Ta hsueh)" are correlated with the individual and the universal ethics of behavior, and connected with the element for overcoming the individual inclination of mind and wickedness. (2) After the individual and subjective human was established, the eight items of the "The Great Learning(Ta hsueh)" were classified into two categories, and coupled up with each two items('Being sincere in their thoughts' with 'Extending to the utmost their knowledge', 'Rectifying their hearts' with 'Investigating things', 'Cultivating their persons' with 'Illustrating illustrious virtue throughout the kingdom', 'Regulating their families' with 'Ordering their own states'). Being based on this, 'Being sincere in their thoughts', 'Rectifying their hearts', 'Cultivating their persons' and 'Regulating their families' were understood as four individual and subjective human-basic-essential activity. Especially, mind, heart, body and family(power) were regarded as the four basic element in human existence and activity, and in correlation with universe and society, set up as the subjective element in Dongmu's epistemology, theory of nature and emotion, theory of morality and theory of moral cultivation.

  • Learning from human behaviors in the real world is essential for human-aware intelligent systems such as smart assistants and autonomous robots. Most of research focuses on correlations between sensory patterns and a label for each activity. However, human activity is a combination of several event contexts and is a narrative story in and of itself. We propose a novel approach of human activity prediction based on event cognition. Egocentric multi-sensor data are collected from an individual's daily life by using a wearable device and smartphone. Event contexts about location, scene and activities are then recognized, and finally the users" daily activities are predicted from a decision rule based on the event contexts. The proposed method has been evaluated on a wearable sensor data collected from the real world over 2 weeks by 2 people. Experimental results showed improved recognition accuracies when using the proposed method comparing to results directly using sensory features.

  • A key to a well-performing human activity recognition (HAR) system through machine learning technique is the availability of a substantial amount of labeled data. Collecting sufficient labeled data is an expensive and time-consuming task. To build a HAR system in a new environment (i.e., the target domain) with very limited labeled data, it is unfavorable to naively exploit the data or trained classifier model from the existing environment (i.e., the source domain) as it is due to the domain difference. While traditional machine learning approaches are unable to address such distribution mismatch, transfer learning approach leverages the utilization of knowledge from existing well-established source domains that help to build an accurate classifier in the target domain. In this work, we propose a transfer learning approach to create an accurate HAR classifier with very limited data through the multitask neural network. The classifier loss function minimization for source and target domain are treated as two different tasks. The knowledge transfer is performed by simultaneously minimizing the loss function of both tasks using a single neural network model. Furthermore, we utilize the unlabeled data in an unsupervised manner to help the model training. The experiment result shows that the proposed work consistently outperforms existing approaches.

  • This qualitative study explores how volunteering to help in early childhood education is conceptualized from the perspectives of three parties involved; university students, university professors, and principals as well as teachers, and children‘s mothers from a local daycare center and a kindergarten. Data was collected through journals, interviews, and several other artifacts, such as student portfolios, and letters from mothers. Findings were as follows: firstly, preservice early childhood teachers defined voluntary activity in early childhood education as a service that requires motivation and responsibility, and as an activity that helps to establish their identities as teachers. Secondly, university professors constructed the system for service learning activities and helped preservice early childhood teachers’ change the view from volunteering activity to volunteering learning. Thirdly, the local community referred to these activities in terms of the partnerships made for children‘s education and the possibility of cooperative childcare. The findings of this study describe the perspectives of parties involved and may be helpful in planning and executing specialized volunteer projects as well as in understanding volunteer behavior.

  • A vector space based augmented structural kinematic (VSASK) feature descriptor is proposed for human activity recognition. An action descriptor is built by integrating the structural and kinematic properties of the actor using vector space based augmented matrix representation. Using the local or global information separately may not provide sufficient action characteristics. The proposed action descriptor combines both the local (pose) and global (position and velocity) features using augmented matrix schema and thereby increases the robustness of the descriptor. A multiclass support vector machine (SVM) is used to learn each action descriptor for the corresponding activity classification and understanding. The performance of the proposed descriptor is experimentally analyzed using the Weizmann and KTH datasets. The average recognition rate for the Weizmann and KTH datasets is 100% and 99.89%, respectively. The computational time for the proposed descriptor learning is 0.003 seconds, which is an improvement of approximately 1.4% over the existing methods.
