Purpose The impact of online reviews is widely acknowledged, with extensive research focused on text-based reviews. However, there's a lack of research regarding reviews in video format. To address this gap, this study aims to explore the connection between company-sponsored product review videos and the extent of directive speech within them. This article analyzed viewer sentiments expressed in video comments based on the level of directive speech used by the presenter. Design/methodology/approach This study involved analyzing speech acts in review videos based on sponsorship and examining consumer reactions through sentiment analysis of comments. We used Speech Act theory to perform the analysis. Findings YouTubers who receive company sponsorship for review videos tend to employ more directive speech. Furthermore, this increased use of directive speech is associated with a higher occurrence of negative consumer comments. This study's outcomes are valuable for the realm of user-generated content and natural language processing, offering practical insights for YouTube marketing strategies.

Online application for survival analysis (OASIS) and its update, OASIS 2, have been widely used for survival analysis in biological and medical sciences. Here, we provide a portable version of OASIS, an all-in-one offline suite, to facilitate secure survival analysis without uploading the data to online servers. OASIS portable provides a virtualized and isolated instance of the OASIS 2 webserver, operating on the users' personal computers, and enables user-friendly survival analysis without internet connection and security issues.

Wireless Internet based in WAP(Wireless Application Protocol) has been a very useful and attractive means picking up information through service irrelavant to time and space. And more the request of user has been diverse. In this paper, we implemented a Diet Menu System using expert knowledge-based rules on the WAP environment. This enables the moving man interested in diet to get information through wireless mobil hand phone. There are only connection-oriented system for this type of service till now. This paper has designed basic expert knowledge rules for result display, verified and implemented for WAP environment.

This paper presents an Interprocessor Communication Network(IPC net) in ATM switching system. In order to supply stable and independent path for processor communication, additional network i.e., Ethernet, is suggested. An Ethernet switch centered on Ethernet binds each processor into a work range. IPC net proposed in this paper assures end-to-end inter-processor connection, uniform 100Mbps Ethernet bandwidth and enhanced user cell throughput of ATM switch with minimum Ethernet supporting block integrated into ATM system

The purpose of this paper is to measure jitter between two server systems. Given 3 empirical models as user and port parallel server types under some conditions of 100 Mbps and optimal CPU temperature suggested by Lee and Kim(2005), our results are shown; jitter was usually measured above 3000 ms in most empirical cases, jumping points were observed around 250 processing traffics, and port parallel model was optimal in our cases.

This paper presents a Prototype system developed for a Bluetooth interfaced VoIP system. The VoIP phone is developed based on tile implementation of a CELP coder on the TI 16bit DSP Processor A PC interfaced with Bluetooth module is used to designing a access point system. Host controller protocol stack is implemented to realize gateway between the wireless and wired line networks. A server application program for user management and call processing, which is based on TCP/IP peer to peer connection, is implemented for tile evaluation of overall interface system.

Korea gas industrial because of received LNG in 1987 was converted by the Gas Safety Management System in relation to city gas, LPG and LNG. Gas accident were caused by treatment problem on the supplier and user, on technical and use management mater, on facilities and goods, and included problem with gas safety connection system. This study is present standard application plan of each department to use planning gas technical standard and gas utilization standard of introduction model than statute for change of self-regulation management system and complicated regulation of examination center and order.

웹 서버 클러스터의 성능 개선을 위한 연구가 다양한 분야에서 이루어졌지만 로그 파일 분석과 같은 방식으로 접속 빈도를 통한 실시간 동적 자원 재분배에 관한 연구에만 대부분 초점을 맞추었다. 본 논문에서는 시구간별 접속 패턴 분석 결과를 기반으로 패턴을 예측하여 자원을 동적으로 재분배하는 메커니즘을 제안한다. 제안한 메커니즘은 불필요한 자원 낭비를 감소시켜 효율적인 자원 재분배를 통해 클러스터의 성능을 향상시킨다. 또한 시구간별 접속 패턴의 유사성을 증명한다.

This study aims to improve plans by analyzing spatial compositions of cohousing common houses, their role depending on the types of users and spaces, and satisfaction from the user-oriented design perspective. For this study, a basic concept was examined based on previous studies and literature reviews. So-Haeng-Ju(Happy House with Communication) Houses 1, 2, and 3 in Seongmisan Village was analyzed. As well, interviews with residents of these houses were conducted to analyze the role of user behavior in common house depending on the types of users and spaces. As a result, it was found that there were common characteristics of roles in an exchange with neighbors, cooperative child-care, and residents' meetings. The time and behavioral types were different depending on the living patterns, characteristics, and family members of residents. User satisfaction with the locations of community facilities including communal kitchen and communal living room, the composition of rooms, communication with residents, and the connection between communal living space and personal living space, was above the average. However, user satisfaction with storage facilities, or defect repair and facility maintenance was low. Most of cohousing common house users were satisfied with the use and size of spaces, and a sense of community, including communication with neighbors beyond the environment and Seongmisan Village. In conclusion, a realistic alternative is required for future cohousing by developing a system regarding human resources networks and cost bearing issues.

Information of social relationship of users on online is useful information for other services such as recommend information of commercial activity. So, there is a lot of studies analysis with connection to visualization of social network. Most of the previous works of visualization focus on representing user's relationship on social network by a complex multi dimension graph. However, this method is difficult to identify the important of relationship to focus on personal user intuitively. In order to resolve above problem, this paper proposes a new visualization method using the user's correlation and user relationship of network node. The proposed method visualizes the hierarchy relationship of users using the internal relation of network reflecting user's message and external relation of network nodes.
