Purpose: More and more marketers use social media platforms to create and spread information called Marketer Generated Content (MGC) to inform consumers of products. MGC often embeds product purchase links, thus directing consumers to online distribution channels for online purchases. This study examined the effect of social media MGC on consumers' willingness to buy online in the anchor of consumers' perspective to answer the question of "how social media generated content support corporate online distribution". Research design, data, and methodology: According to the means-end-chain theory, we introduce perceived value and continuous following intention as chain mediators to explain the mechanism of MGC influence on consumers' online purchase intention and consider product type to discuss boundary conditions. Two experiments were designed to test hypothesizes. Results and Conclusion: First, emotional MGC (vs. informational MGC) has lower (higher) perceived utility (hedonic) value. Second, perceived value has a significant mediate role in the effect of MGC on continuous following intention. Third, perceived value and continuous following intention significantly and sequentially mediated the effect of MGC on online purchase intention. Through the sequential mediations of perceived utility value and continuous following intention, Informational MGC of search products significantly increase online purchase intentions. Another parallel sequential mediation, including perceived hedonic, emotional MGC of experience products, partially enhanced online purchase intentions. Finally, this study gives implications for how corporates can use social media MGC to promote product sales online.

Synchronization between media is an important aspect in the design of multimedia streaming system. This paper proposes a precise media synchronization mechanism for digital video and audio transport over IP networks. To support synchronization between video and audio bitstreams transported over IP networks, RTP/RTCP protocol suite is usually employed. To provide a precise mechanism for media synchronization between video and audio, we suggest an efficient media synchronization algorithm based on NPT (Normal Play Time) which can be derivable from the timestamp information in the header part of RTP packet generated for the transport of video and audio streams. With the proposed method, we do not need to send and process any RTCP SR (sender report) packet which is required for conventional media synchronization scheme, and accordingly could reduce the number of required UDP ports and the amount of control traffic injected into the network.

In this paper, an adaptive algorithm is proposed in streaming MPEG-4 contents with fluctuating resource amount such as throughput of network conditions. MPEG-4 is the international standard for audiovisual presentation which is composed of object based media streams. The proposed technique provides the media stream corresponding an object with multiple media streams with different qualities and bit rate in order to support object based scalability to the MPEG-4 content. In addition, making the object streams adaptable, a feasible stream set selected from the multiple streams for transmission with optimal quality in the form of the current status.

MPEG-4 content is streaming media that are composed of different types of media objects, organized in a hierarchical fashion. This paper proposes scene composition model for authoring MPEG-4 contents which can support object based interactions. And we have developed MPEG-4 contents authoring tool applied the proposed scene composition model as intermediate data structure. Particularly, for supporting interoperability between multimedia contents, the scene composition model should be used independent of file format. So visual scene composed of media objects on the from of scene composition tree can be transformed variable data format including BIFS, scene description from proposed by MPEG-4 standard and also support the extension of capability.

Due to Thailand's nuclear energy public acceptance problem, the understanding of nuclear energy public perception was the key factor affecting to re-consideration of the nuclear energy program. Thailand Institute of Nuclear Technology and its alliances together developed the classification model for the nuclear energy public perception from the big data comments on social media using Facebook using deep transfer learning. The objective was to insight into the Thailand nuclear energy public perception on Facebook social media platform using sentiment analysis. The supervised learning was used to generate up-to-date classification model with more than 80% accuracy to classify the public perception on nuclear power plant news on Facebook from 2009 to 2022. The majority of neutral sentiments (80%) represented the opportunity for Thailand to convince people to receive a better nuclear perception. Negative sentiments (14%) showed support for other alternative energies due to nuclear accident concerns while positive sentiments (6%) expressed support for innovative nuclear technologies.

Purpose: This study provides information for the development of educational programs for improving awareness of support to the elderly among adolescents. Methods: The 350 students of high schools located in Seoul were selected as subjects and surveyed using structured questionnaires during 11th~15th of April in 2014. The 327 subjects were used for analysis and the response rate was 93.4%. SPSS/WIN18.0 program was performed for t-test, ANOVA and regression analysis. Results: First, adolescents with parents aged over 50 compared to those with parents younger than 40 showed high level of awareness of support to the elderly. The high level of cognitive factors including image and perception towards the elderly (t=3.07, p=.01) were significant factors of awareness of support to the elderly. In experiential factors, adolescents with extensive influence of media and experiences with cohabitation with grandparents, and experiences with voluntary service activities were statistically significant with the high level of awareness of support to the elderly. Second, in regression analysis, adolescents' economic support awareness was higher with the stronger influence in the elderly-related media (${\beta}=.221$, p=.032). The emotional support awareness was higher among the eldest sons (${\beta}=.220$, p=.017) and perception (${\beta}=.352$, p=.001) to elderly (${\beta}=.221$, p=.032). Physical support awareness was higher when the positive image for the elderly (${\beta}=.223$, p=.016) and the high perception towards the elderly (${\beta}=.293$, p=.007). Conclusion: The awareness of support to the elderly should be constantly strengthened to the adolescents. Despite the rapid increase of the elderly, studies are not sufficient. Further research will be necessary.

对营销和广告经理来说, 理解消费者的偏好和使用的媒体类型是非常有必要的, 尤其是在如今市场细分的情况下. 清晰的理解能帮助经理更有效的选择合适的媒体. 而且由于性格特征的不同, 个人对媒体类型的选择和使用都不相同. 本文测试了一个性格特征, 即感知追求. 这是在测试 "新" 媒体偏好和使用的文献中尚未出现的. 感知追求是被定义为 "一种对变化, 新颖和复杂的感觉的需要和经历. 以及为承担这些经历愿意承受生理的和社会的风险" (Zuckerman 1979). 根据文献回顾, 我们提出了6个假设. 我们尤其关注使用与满足理论(Katz 1959), 这个理论解释了为什么人们选择媒体类型和他们使用不同媒体类型的动机的原因. 目前的理论表明高感知追求者(HSS), 由于他们对新颖, 激励和非传统的内容和想象的需要, 他们会更多的使用新媒体. 因此, 我们假设高感知追求者比低感知追求者(LSS)(H2a)或中等感知追求者(MSS)(H2b)会更多的使用网络而不是广播(H1a)或印刷媒体(H1b). 另外, 高感知追求者有更多的社交活动及朋友, 因此他们会比低感知追求者(a) 和中等感知追求者(b)更多的使用社交网络网页例如Facebook/MySpace(H3) 以及聊天室(H4). 感知追求者可以显示出一系列的行为包括抑制解除. 我们认为具有高水平去抑制的人们比低水平或中等水平的人们会更多的使用社交网络如Facebook/MySpace (H5) 和聊天室(H6). 我们的数据来源于对参加极限运动的参与者的网上调查. 为得到这个群组的信息, 我们使用雪球样本技术的提高版, 即连锁推荐方法来选择应答者. 这种方法被认为是对隐藏人群进行有效估算的方法(Heckathorn, 1997). 最终的有效样本包括1108名应答者. 主要是年轻人(56.36%在34岁以下), 男性(86.1%)和中产阶级(58.7%的家庭收入超过50,000美元). 我们用这个样本来进行感知追求的研究. 我们用简要感知追求量表来测试感知追求(Hoyle et al. 2007). 我们用自我报告使用过的不同媒体类型来测量媒体使用. 结果并不支持H1a和b. 高感知追求者并没有更多的使用网络这样的媒体. 事实上, 同其他的媒体类型相比, 这个平均水平是较低的. 高感知追求者使用最多的媒体类型时印刷媒体, 这说明了一种对主流的反抗. 结果支持H2a和b. 高感知追求者比低感知或中等感知追求者更多的使用网络. 进一步的分析揭示了在高感知和低感知追求者之间在使用印刷媒体方面有显著不同. 高感知追求者在他们感兴趣的极限运动方面会追求更专业的印刷出版物. 假设3a和b 揭示了高感知追求者比低感知或中等感知追求者更多的使用Facebook/MySpace. 在使用聊天室方面低感知和高感知追求者之间没有显著差距. 所以结果也不支持假设H4a, 但是H4b的结果是显著的. 不同抑制解除水平的应答者被认为使用Facebook/MySpace 和聊天室的水平也不同. 去抑制水平高比低水平或中等水平的使用Facebook/MySpace的水平高. 所以H5a和b 被支持. 类似的, H6b也被支持. 去抑制水平高的人们使用聊天室的概率显著多于中等水平的但并不多于低水平的人们(H6a). 这些结果为管理者提供了一些有趣的见解. 第一, 尽管高感知追求者比低感知或中等感知追求者更多的使用在线媒体, 但他们使用在线媒体仍然少于印刷或广播媒体. 广告执行者们不应该对这个重要的客户群过分的强调在线媒体. 第二, 社交媒体, 例如Facebook/MySpace和聊天室会是接近这个群体的有潜力的方法. 最后, 对去抑制水平高的群体, 有公共关系方面的启示. 这些个体更倾向于一些社会风险的行为. 这些直接的启示包括因特网捕食者和未来的雇主. 本研究的一个不足是受访者都是参与极限运动的. 这本身就是一个高感知追求者活动. 更大范围的人群需要被测试.

Based on the transfer matrix approach and integral transforms, a solution method is developed for the stress analysis of axisymmetrically loaded transversely isotropic elastic media with generalized interlayer and support conditions. Transfer functions (Green's functions in the transformed domain) are obtained in explicit integral form. For several problems of practical interest with different loading and support conditions, solutions are worked out in detail. For the inversion operation, an efficient technique is introduced to remedy the slow convergence of numerical integrals involving oscillating functions. Several illustrative examples are considered and numerical results are presented.
