  • We analyzed the relationships between the co-authorship network centralities and the research performance indicators with the authors and the number of citations of the papers published for 10 years in Korean library and information science journals. In particular, the research performance indicators were calculated with normal counting and with fractional counting also. As a result of correlation analysis between the variables by setting the different ranges of the author groups to be analyzed according to the number of articles, it was possible to explain the inconsistent results of the previous studies on the correlations between the researchers' citation indicators and their co-authorship network centralities. Overall, the degree of co-authorship activities measured by collaboration coefficient showed no or negatively correlated with research performance. There were statistically significant positive correlations between the centralities and the research performance indicators, but the correlation was not significant in the analysis of the top 30 authors by number of articles.

  • Complementary and alternative medicine (CAM) practice is still popular among the Malaysian population nowadays although western or allopathic medicine is the first line of treatment. Dissatisfaction with health services and therapeutic effects of western medicine or preference for holistic, integrative approach in treatment are common reasons favouring the increasing popularity of CAM practices. The efforts toward integration of CAM and western medicine in Malaysia were rather slow and in a piece-meal fashion. Strategic efforts in strengthening government and self-regulation among practitioners, formalizing education, promoting research, and cultivating national and international networks are necessary to achieve an integrative system. Regulations to restrict the practice and sale of CAM products to licensed practitioners, strict and mandatory registration of the practitioners, inclusion of CAM in essential medicines list, and pricing regulations must be comprehensively discussed. Development of curriculum, offers of scholarship and incentives, promotion of courses and seminars for professionals is necessary to increase the numbers of CAM experts. Malaysia should follow the efforts of other countries on the production and documentation of local CAM data, allocation of funding, and establishment of research centres to assess the efficacy of potentially useful local products. Local and international collaboration in research and continuous education is important for exchange of knowledge and skills. In conclusion more coordinated efforts in regulation of CAM practice and products, formalizing CAM training and education would significantly move the process forward and allow the public to enjoy more health benefits from CAM practice in Malaysia.

  • Ubiquitous home refers not only to home but also to logical space, including a wide range of out-home personal devices such as mobile phones, PDAs, laptops, car navigators, and office PCs. There are certain connection barriers among the devices, such as the dynamic IP address, NAT. In a home network, various devices coexist in heterogeneous networks, such as IP, IEEE1394, PLC, Bluetooth, ZigBee, UWB, and IrDA, all of which lack interoperability due to their different physical transmission characteristics and protocols. In ubiquitous home where an unrestricted collaboration of the devices is essential to offer services that meet the users' requirements, free interoperability among the devices must be guaranteed. This paper proposes a networking model for interoperability of the heterogeneous devices in a ubiquitous home based on a virtual overlay network which hides the complicated physical network configurations and heterogeneity of the service protocols.

  • Leading up to the 2019 presidential election in Indonesia, campaigns have emerged through social media, particularly Twitter, using various hashtags, such as #2019GantiPresiden (2019 Change President) and #TetapJokowi (Always Jokowi). This paper tries to understand the presidential candidates' power map in forming opinions and influencing voter behavior by analyzing Twitter from August 6, 2018 to September 15, 2018, just before the beginning of the official campaign period, by searching for the keyword "pemilihan presiden RI Tahun 2019" (RI presidential election in 2019). According to our NodeXL's analysis, there were 1,650 active Twitter users talking about the 2019 presidential election. The 1,650 Twitter users have formed a communication network of 46,750 relationships formed from messages in the form of tweets, comments, and retweets. Our analysis found that those mentioning "pilihan presiden 2019" form large communication networks around four clusters: one for each of the two candidates (Jokowi and Prabowo) and two for opinion leaders who are undecided about the election (Gus Mus and Mas Piyu). GusMus is a religious leader, as an official of the PBNU Rais Syuriah (an Islamic organization) and has a large following both on and off Twitter. "MasPiyu" is an unidentified Twitter user; he only has a large following on Twitter, but does not have support offline.

  • The purpose of this paper is to analyze 1) who created and distributed fake news, 2) the distribution channels of fake news, 3) who fake news has targeted, and 4) the effects on voting and the impact of fake news on Korean politics. In South Korea, fake news was mainly created by candidates or election campaigns. The reason is that in the wake of the impeachment of President Park Guen Hye, all the political parties in Korea used fake news as a means of mobilizing supporters for each of their candidates or parties to gain an advantage in situations involving political divisions and confrontations between the pro-impeachment, progressive young generation and anti-impeachment, conservative senior generation. Voters' media usage patterns were polarized through social network services (SNS) media and television. Fake news was mostly received through these two media outlets. According to the spreading structure of fake news in Korea, the younger generation generally uses SNS posts intended for unspecified individuals, and the older generation uses closed SNS like KakaoTalk or Naver's BAND. In the end, it is typically characteristic of the older generation to spread fake news through existing offline human networks. In the 2017 presidential election, fake news has been confirmed to have the effect of mobilizing supporters for each political party. In the presidential election, an increase in voter turnout was confirmed among those in their 20s and those in their 60s or older. Evidently, fake news influenced the election of Moon Jae-In. The influence of fake news is expected to grow further as ideological polarization and consequent political polarization continues to intensify in South Korea.

  • The purpose of this paper is to construct a cooperation network for multicultural information services. It is suggested that a network for multicultural information helps those who limited information resources. Following investigation of the related information resources-422 online sites in 395 groups-it was found that the activity of non-public groups is higher than that of public groups and that all related groups offer various information services to multicultural people: education (24.5%), culture (18.4%), human rights (12.7%), general life (8.9%), and etc. The paper suggests the sharing of the information of internal related groups and collaboration with th embassies and cultural centers of East Asian country in order to construct a multicultural information service.

  • LTE-Advanced network will form the high-speed IP backbone in collaboration with heterogeneous radio access networks for dynamic optimized resource utilization. In order to implement more innovative and attractive services such as U-Cloud streaming, LBS and mobile smart TV, a mobile terminal needs to support multiple sessions simultaneously. Efficient resource allocation schemes are necessary to maintain QoS of multiple sessions because service continuity may be defected by delay and information loss during handover. This paper proposes a resource allocation scheme to accommodate multiple sessions in a mobile terminal on handover period based on session priority mechanism. Simulation is focused on the forced termination probability of handover sessions. Simulation results show that our proposed method provides a better performance than the conventional method.

  • In shipyard site, a ship is constructed by integrating lots of modules that are made in several sites with different capabilities and specifications. Recently, it needs to make a shipyard to be smart communicating various multimedia information with wired and wireless broadband networks between hierarchical shipyards. In this paper, we propose an additional function of an LTE femtocell local gateway at a remote shipyard, an information exchange method between hierarchical shipyards, and an offload method to separate the general traffic. To reduce traffic of duplicated requests in shipyard, we apply a D2D communication scheme for supporting communication between shipyard equipments without IP service network. Hence, it is expected to increase the productivity of shipyard industry with mobile communications, D2D and broadband Internet technologies.

  • The purpose of this study is to analyze the status of interlibrary loan (ILL) services using data from its transection. While analyzing the ILL data, agenda to improve the quality of services was identified, and suggestions were made to address them. Three data sets including National Inter-Libary Loan data, National Library Statistics System data, and local inter-library loan system analysis data were collected and analyzed. The results indicate that the size of transaction in ILL is getting bigger. The local ILL, particularly, was expanded and actively used by people. Additionally, the type of library participating in ILL networks was diverse and the number of library was increasing. Finally, this study discussed the tool to measure the contribution of each library in ILL. The collection uniqueness and collaboration index of library as well as the ILL statistics should be considered in the process of the tool development.

  • This paper analyzes previous work on publish/subscribe in mobile ad-hoc networks with respect to collaboration methods among distributed event brokers. Our experiments suggest that approaches building event delivery structures are suitable for a scenario where there are events of various types each of which is consumed by a few subscribers. However, these approaches based on independent periodic exchange of network topology information may fail to reflect the up-to-date information when building event delivery paths. For this reason they do not correctly recover a broken path caused by node mobility, which results in lower event delivery rates. This paper proposes a scheme for building and maintaining event delivery paths based on advertisements initiated by and hence propagated from the root node. This guarantees correct recovery of event delivery paths within each period. Our experiments show that, our proposed scheme gives a better event delivery ratio with lower overhead.
