Recent IPTV services still remain as simple broadcasting services that cannot make the most of interactive features together with various content-associated data. So, IPTV providers are making efforts to break from monopolistic style, so as increasing the user's participation m service. However there is an interoperability problem because no common solution is employed across different providers. To solve this problem, there needs to be a framework for a framework for generating, sharing and distributing package contents. In this paper, we propose user-centered package contents application framework for interactive IPTV services. We also design a package content authoring and consuming system which plays core parts in the proposed framework.

Effective mastering and learning of basic organic chemical concepts is pivotal to ensure students continue to excel to the higher levels of organic chemistry learning. Concept learning is crucial for first-year organic chemistry students so that they can comprehend and understand a concept better and able to make connection to problems. In the present paper, the authors have implemented the Interactive Anonymous Quiz (IAQ) with "must-have" features in the organic chemistry course as a teaching tool to instill students' interest and enhance conceptual understanding in organic chemistry. The effectiveness of this activity was examined and evaluated through students' reflective writing. Students showed positive learning outcome on the implemented activity as reflected by the reflective writings. In addition, this activity could be employed as an activity to check on students' concept understanding, to instill students' interest in organic chemistry course and to improve on students' weakest topic in organic chemistry in the future classes.

The development of digital technology has not only led to the development of expressive technology, but also to change in the process of production, expression media, production formats and methods, and communication with the audience. In one form, motion poster using LCD display instead of paper poster was introduced. This not only suggests the generation of posters with sound and movement on the ground, but also the possibility of expansion using the features of a platform called LCD displays. As part of this extension, this paper focuses on the "interactions" element and suggests a new interactive motion poster.

In this paper, we propose an interactive system that generates emotional expressions from arm gestures. By extracting relevant features from key frames, we can infer emotions from arm gestures. The necessary factor for real-time animation is tremendous frame rates. Thus, we propose processing facial emotion expression with 3D application for minimizing animation time. And we propose a method for matching frames and actions. By matching image sequences of exagerrated arm gestures from participants, they feel that they are communicating directly with the portraits.

This paper proposes a dynamic gesture recognition algorithm using SVM(Support Vector Machine) which is suitable for multi-dimension classification. First of all, the proposed algorithm locates the beginning and end of the gestures on the video frames at the Kinect camera, spots meaningful gesture frames, and normalizes the number of frames. Then, for gesture recognition, the algorithm extracts gesture features using body parts' positions and relations among the parts based on the human model from the normalized frames. C-SVM for each dynamic gesture is trained using training data which consists of positive data and negative data. The final gesture is chosen with the largest value of C-SVM values. The proposed gesture recognition algorithm can be applied to the interactive storybook as gesture interface.

One of the objectives and aspirations of scientists and engineers ever since the development of computers has been to interact naturally with machines. Hence features of artificial intelligence (AI) like natural language processing and natural language generation were developed. The field of AI that is thought to be expanding the fastest is interactive conversational systems. Numerous businesses have created various Virtual Personal Assistants (VPAs) using these technologies, including Apple's Siri, Amazon's Alexa, and Google Assistant, among others. Even though many chatbots have been introduced through the years to diagnose or treat psychological disorders, we are yet to have a user-friendly chatbot available. A smart generative cognitive behavioral therapy with spoken dialogue systems support was then developed using a model Persona Perception (P2) bot with Generative Pre-trained Transformer-2 (GPT-2). The model was then implemented using modern technologies in VPAs like voice recognition, Natural Language Understanding (NLU), and text-to-speech. This system is a magnificent device to help with voice-based systems because it can have therapeutic discussions with the users utilizing text and vocal interactive user experience.

Based on the integrated analysis of the existing literature, this study combined with S-O-R model to explore the impact of e-commerce live broadcast characteristics on consumers' impulse purchase intention. Among them, interactive, entertaining, economical and visual features are selected as the features of e-commerce live broadcast; Select pleasure and arousal to measure consumer sentiment, and build a theoretical model among e-commerce live broadcast features, consumer sentiment and consumers' impulsive purchase intention to specifically explore the impact of each feature on emotion and the further impact of emotion on impulsive purchase intention.

I would like to propose the initiation of co-operating research about $\ulcornerIndustrial$ structure between Japan and $Korea\lrcorner.$ The purpose of this investigation is to study about appropriate system of industrial structure Japan and Korea including interactive relation. In future, tile interactive relationship of industrial structure should be desided by the investigation of a characterization about alocality, a racial character, a existence of resources, a weather, a history and natural features of a region. According to these investigation, frictionless structure of industrial society of each country will be born. The most appropriate researcher's group is Consulting Engineer's Association of each country, because they are independent from a national benefite and a profit of enterprise. According to the above reason. I propose to start the co-operating research project immediately.

The development and operation of brand programs can help regional Culture & Art Centers provide sustainable contents to local citizens. The study of domestic and foreign examples shows that successful, competitive brand programs share common characteristics: interactive features; systematization and manualization of programs and unique, individual, universal themes.

Information network technologies introduce a new education environment. Cyber education is growing rapidly as a field of practice especially in distance education system. The development of multimedia environment based on such technology as graphics, image, voice, and video, personal computer systems use has become the media for interactive teaching-teaming service. These features have made integrated multimedia education feasible. This research suggested a direction for the development of an interactive distance education system. I have developed an education system which cooperate problem bank and learning system. This system support arbitration of the relative difficulty in the problem bank database. An ongoing version of this research was evaluated. Those findings reveal several factors that influence how the proposed system can be tailored to the students' perspectives in order to come up with the enhanced version of this system.
