  • Media utilization in colleges of education in Nigeria is compulsory to train pre-service teachers. Psychological variables (emotional intelligence, and self-efficacy) and media improvisation were investigated on media resources utilization among lecturers in colleges of education in the South-West, Nigeria. The descriptive design was adopted and multi-staged procedure was used to select 812 (493 males; 319 females). Emotional intelligence (r = 0.79), media improvisation (r = 0.71), self-efficacy (r = 0.85 and media resources utilization r = 0.96) scales were used for data collection. The data were analyzed using descriptive statistics and Pearson product moment at 0.05 level of significance. The level of emotional intelligence, self-efficacy and media improvisation were high. Significant relationship existed among: emotional intelligence (r = 0.42), Media improvisation (r = 0.46) and Teaching self-efficacy (r = 0.31) to media resources utilization. It recommended that lecturers' emotional intelligence, self-efficacy and media improvisation are to be promoted in colleges of education.

  • A cross sectional survey method was used to determine the utilization of e-resources and their influence on the reading culture of 119 undergraduate students registered with the JD Amin library of Federal University Dutse. The data collected was analysed using both descriptive (frequency counts and means) and inferential statistics (regression analysis). The research found that databases (mean=4.00) and e-journal (mean=4.00) are available to the undergraduate students. It further found that e-resources are often utilized by the undergraduate student, with social media (mean=4.00), databases (mean=4.00) and e-journal (mean=4.00). the most commonly used e-resources. It was also found that erratic power supply (mean=3.91) and inability to seek, obtain and evaluate information (mean=3.67) are the prominent factors hindering the utilization of e-resources. The regression analysis rejected the null hypotheses of the study where it shows that the level of utilization of e-resources have positive statistical correlation (r=0.772) with the reading culture of undergraduate students. The study proposed a conceptual model for the sustainable reading culture of students by libraries providing of e-resources. The general conclusion of the research is that e-resources are necessary tools and are moderately available and adequately utilized for influencing reading culture. The study recommended that Internet facilities should be made available to undergraduate students to facilitate more utilization of e-resources.

  • Virtual Machine (VM) resource management is crucial to satisfy the Quality of Service (QoS) demands of various multimedia services in a media cloud platform. To this end, this paper presents a VM resource allocation model that dynamically and optimally utilizes VM resources to satisfy QoS requirements of media-rich cloud services or applications. It additionally maintains high system utilization by avoiding the over-provisioning of VM resources to services or applications. The objective is to 1) minimize the number of physical machines for cost reduction and energy saving; 2) control the processing delay of media services to improve response time; and 3) achieve load balancing or overall utilization of physical resources. The proposed VM allocation is mapped into the multidimensional bin-packing problem, which is NP-complete. To solve this problem, we have designed a Mixed Integer Linear Programming (MILP) model, as well as heuristics for quantitatively optimizing the VM allocation. The simulation results show that our scheme outperforms the existing VM allocation schemes in a media cloud environment, in terms of cost reduction, response time reduction and QoS guarantee.

  • 멀티미디어 콘텐츠 서비스 산업의 경쟁이 치열해 지면서 고객만족을 위한 다양한 정책들이 제시되고 있다. 이러한 정책 중에는 서비스를 이용하는 고객들을 분류하여 등급을 산정하고 등급에 따라 미디어 서버의 자원을 고정적으로 할당하는 정책도 있다. 이 정책의 문제점은 값비싼 미디어 서버의 자원을 효율적으로 사용하지 못할 수도 있다는 점이다. 본 논문에서는 이러한 문제점을 해결하기 위하여 ACRFA(Adaptive Client Request Filtering Algorithm)를 제안하고자 한다. 이것은 고객들의 등급을 차등화하고 유연성있는 자원할당 방법을 적용하기 위한 것이다. 높은 등급의 고객에게 더 많은 자원을 할당하게 하여 고객의 만족도를 높이면서 동시에 미디어 서버의 자원의 일부는 등급별로 고정할당하고 나머지 일부는 공용자원으로 활용하게 하는 방안을 제안하고자 한다.

  • Media improvisation among lecturers in colleges is inevitable because of insufficient media resources for utilization. The study investigated media improvisation in the state -owned colleges of education in the South-West, Nigeria. The study is anchored on Media Richness Theory. Stratified sampling technique was adopted to select 812 lecturers. Media improvisation scale (r = .71) was used for data collection and T-test statistical method was adopted for data analysis. The result showed that there was no significant differences between media improvisation of Art/Social Science and Science lecturers (Crit - t = 1.96, Cal. t = 821, df = 278, p>.05) and that of lecturers in the School of Art/Social Sciences and Vocational/Technical Education (Crit. t = 1.96, Cal. t = .136, df = 276, p>.05). Significant difference did not exit between that of the Schools of Languages and Education (Crit. t = 1.96, Cal. t = 1.946, dif. = 288 p<.05) . It is recommended that media improvisation of lecturers in schools should be encouraged and improved upon.

  • 최근 홈 네트워크 시장에서는 가전 업체를 중심으로 DLNA(Digital Living Network Alliance) 기술 기반 홈 미디어 네트워크 서비스가 활발히 제공되기 시작하고 있다. 현재 DLNA 미디어 기기와 함께 일반적으로 제공되는 DLNA 네트워킹 소프트웨어는 서버 기능, 렌더러 기능 및 디바이스 제어 기능 모두를 포함한 통합 소프트웨어의 성격이 강하다. 그러나 홈 미디어 네트워크 환경에서는 하나의 기기가 여러 기능을 동시에 내장할 필요가 없고 자주 사용하는 기능이 정해져 있는 경우가 많다. 스마트TV의 재생 기능, NAS(Network Attached Storage)의 미디어 저장 기능과 같이 각각의 기기가 특정 역할을 수행하는 홈 미디어 네트워크 환경에서 DLNA 통합 소프트웨어 활용은 오히려 네트워킹 및 프로세싱 측면에서 낭비를 유발한다. 본 논문에서는 현재의 통합 기능 DLNA 네트워킹 소프트웨어를 분석하고, DLNA 디바이스 클래스를 근거로 홈 미디어 기기의 자원을 효율적으로 이용하는 기기 별 DLNA 소프트웨어 모델을 제시한다. 또한 제시한 DLNA 소프트웨어 모델 중 스마트TV 및 스마트폰 용 DLNA 소프트웨어를 구현해 일반적인 DLNA 네트워킹 소프트웨어와의 자원 효율성을 비교한다.

  • Background and objective: Instagram, an image-based social media, is being used as an important outlet for the communication and place marketing of public spaces. The purpose of this paper was to analyze how types of place-based content affect user reactions (Likes and Comments) on Instagram in order to provide basic data on the operation and utilization of social media by public places such as botanical gardens and arboretums. Methods: A total of 850 posts uploaded to the Instagram account of Kew Gardens from November 6, 2014 to July 3, 2020 were classified using 14 subject codes. Multiple regression analysis was performed to evaluate the user's reaction between the dependent variables ("Likes", "Comments") and the independent variables (14 subject codes). Results: The findings showed that user reactions appear to differ depending on the typology of the content, and "Likes" and "Comments" were presented in independent behavioral reactions. In particular, "close-ups of plants (botanic, macro)," "plant colony (botanic, wide)," "place-specific landscape (building, landscape)," "anniversary" and "information" showed positive impacts on both "Likes" and "Comments"which could lead to electronic word-of-mouth and content sharing. Conclusion: Based on these findings, it can be argued that the typology of a botanical garden's content can be used to determine factors that affect the immediate reactions and enhance engagement with users.
