In recent days, the number of users having multiple devices according to time and places continue to increases with the help of wide spreading plurality of mobile devices. Consequently, the need for a user to share a media content on his/her multiple devices; furthermore, this movement brings the expansion of N-screen service focusing on connectivity, mobility, and integrity. N-screen service is platform that mediates the use of content or services on multiple devices with the continuous playing scheme. However, N-screen services have the problem of being provided exclusively by a service provider. This paper aims to implement a continuous playing scheme based on RESTfull and on an open service platform; the prototype was successfully implemented on the Android - PC environment.

This study investigates the determinants of continuous user intention of playing on-line games. Based on the data collected through on-line survey, we find that telepresense and commitment influence on the perceived utility of on-line games which, in turn, has effects on continuous user intention of and information sharing among on-line game players. In addition, the findings support the premise that the method of playing game and challenges influence on commitment, whereas rewards for playing game do not. As another determinant of perceived utility of on-line games, telepresense is found to be guided by diplomatic system and storytelling in on-line games.

The purpose of this study is to analyze the effects of unstructured and spontaeous role-playing in pro-social behavior of a child. The experimental group in this study is 7 children who go to after-school class in J. social welfare facility and the controlled group is 7 children in composition class., While the experimental group did role-playing with each other the control group did not have any treatment, In order to find out effects of an experiment pre-test first post-test and second post-test were done. The results can be concluded as following. First in pre-test the degree of behavior resulted the same in experimental group and in controlled group. However in the first post-test the pro-social behavior of the experimental group with role-playing showed an improve than that of the controlled group. Therefore it can be emphasized once more that the role-playing improves pro-social behavior of a child. Second in the second post-test done 2 moth after the role-playing it was found that the pro-social behavior of experimental group keep the improved points as in the first post-test Therefore it can be concluded that the effect of role-playing on pro-social behavior of a child is continuous.

Game bot playing is one of the main risks in Massively Multi-Online Role Playing Games(MMORPG) because it damages overall game playing environment, especially the balance of the in-game economy. There have been many studies to detect game bot. However, the previous detection models require continuous maintenance efforts to train and learn the game bots' patterns whenever the game contents change. In this work, we have proposed a machine learning technique using the self-similarity property that is an intrinsic attribute in game bots and automated maintenance system. We have tested our method and implemented a system to major three commercial games in South Korea. As a result, our proposed system can detect and classify game bots with high accuracy.

Xiaohongshu, a community-centric social media platform, has pioneered a unique e-commerce model known as 'buyer commerce,' leveraging user-generated content (UGC). Distinctively, Xiaohongshu Live Commerce focuses on fostering deep user relationships and providing superior product and information services, crucial for sustained consumer engagement. This study investigates consumer behavior in purchasing health functional foods via Xiaohongshu Live Commerce, aiming to understand the determinants of continuous usage intention. A novel theoretical framework was devised by integrating the Expectation Confirmation Model (ECM) and the Task-Technology Fit (TTF) model. The research model scrutinizes the impact of Xiaohongshu Live Commerce characteristics, such as perceived usefulness and perceived online intimacy, on task-technology fit. Additionally, it examines the moderating role of perceived risk specific to health functional foods and the influence of expectation confirmation on perceived usefulness, online intimacy, and task-technology fit, alongside their effects on satisfaction and continuous usage intention. The findings reveal that expectation confirmation positively influences perceived usefulness, online intimacy, and task-technology fit. Perceived usefulness significantly enhances task-technology fit, while perceived online intimacy and risk do not significantly affect task-technology fit. Moreover, perceived usefulness and intimacy positively impact consumer satisfaction and continuous usage intention, with task-technology fit playing a pivotal role. Perceived risk moderates the relationship between perceived usefulness and task-technology fit. These insights suggest that companies can augment consumer satisfaction and continuous usage intentions by enhancing the perceived usefulness of technology, effectively managing perceived risks, and continually improving user experience

Recently various handheld multimedia devices are spreading, and users want to share media contents across their own multiple devices. Conventional synchronization techniques for N-screen services can continuously play contents by switching from an initial device to a new device. In this case, even if a new device plays continuously contents, the initial device stops playing them. In this paper, we propose a synchronization technique in which multiple devices can share and continuously play same contents simultaneously by gathering and passing URI and current play-time of the contents. The proposed synchronization technique is built on UPnP and DLNA, and tested by implementing a wireless home media network system.

The purpose of this research is to study methods for performing transition that have visual representation of corresponding animations with no bounce in subsequently recognized user information when attempting to interact with a virtual 3D character in real-time using user motion. If the transitions of the animation are needed owing to a variety of external environments, continuous recognition of user information is required to correspond to the motion. The proposed method includes linear interpolation of the transition using cross-fades and blending techniques. The normalized playing time of the source animation was utilized for automatically calculating the transition interpolation length of the target animation and also as the criteria in selecting the crossfades and blending techniques. In particular, in the case of blending, the weighting value based on the degree of similarity between two animations is used as a blending parameter. Accordingly, transitions for visually excellent animation are performed on interactive holographic projection systems.

3D MMORPG(Massive Multi-play Outline Role Playing Game) 게임은 넓은 3차원원지형을 실시간으로 표현되어야 하며, 많은 어려움이 따른다. 본 논문에서는 이러한 지형 처리를 위하여 메쉬나 버텍스, 혹은 폴리곤으로 사실적인 지형처리와 렌드링 속도 향상을 위하여 3차원 폴리곤을 동적으로 생성시키는 방법을 이용하려고 한다. 넓은 지형을 처리하기 위해서는 전체를 한번에 표현하기보다는 페이지 단위로 처리하기 위하여 격자화된 타일로 이루어진 맵으로 처리할 수 있다. Height field 처리 기법은 일정한 영역을 페이지 단위로 구분하고 처리할 수 있다. 옥트리를 이용하여 공간을 입체적인 컬링 방법으로 분할하고, 이를 세부 수준으로 나누어 처리하기 위해 CLOD(Continuous Level of Detail) 개념을 적용할 수 있다. 거리의 변화에 따라 지명을 표현하는 vertex들을 병합 또는 삭제함으로써 그 표현의 정도를 동적으로 달리 할 수 있는 CLOD를 이용하여 카메라의 위치와 방향에 따라 적절한 폴리곤을 생성해 낼 수 있다. 본 논문은 3 차원의 넓은 외부 지형을 실시간으로 처리할 경우 발생되는 그래픽 문제를 해결하기 위해 사용되는 방법 중에서 대표적인 방법을 통하여 효율적인 처리 기법을 제시하려 한다.

Tribologicsl diagnostics as the ensemble of means and methods of continuous monitoring of the state of friction characteristics of moving junctions is playing an ever important part in the development of friction, lubrication, and wear theory end practice. The scheme presenting the main areas of tribological diagnostics is given in Fig. I. This growing part of TD is determined by the general tendency of modern technology, expressed in an attempt to organically combine the functions of measuring, evaluating,and predicting the parameters and characteristics of the processee taking place in the operating device. The logical result of this integration in future is the closed system correcting its operation in accordance with sn established program. Unfortunately, tribotechnicsl devices are still very far from such an ideal system at the present time. While in the friction assemblies with hydrodynamic lubrication it is possible in the first approximation to realize feed-backs in the lubricant circulation system with the aid of monitoring of the pressure, temperature and filtration, in the systems operating without lubrication and with boundary lubricetion even the process of selection of the diagnostic parameters has not been completed.
