What are the differences between science communication and science culture? This paper discusses the relationship between 'science communication' and 'science culture', with a consideration of recent activities and endeavours aiming public's understanding of science. For this, it starts with the outcomes and significance of the 9th International Conference on Public Communication of Science and Technology(PCST-9), with a theme of "Scientific Culture for Global Citizenship", held in Seoul May, 2006. Then, it discusses 'Public Understanding of Science(PUS)' to which the PCST network movement is linked, in comparison with 'Popularization of Science(PS)' and 'Science and Society(S&S)'. While PS was one directional movement conveying scientific knowledge to the public, PUS appeared from 1980s was an intentional effort for activating science communication through mass media. Whereas, a recent S&S movement emphasizes dialogue between science and society. And it then introduces theoretical as well as functional definitions of 'science culture' particulary in Korean and explains how the concept of science communication has considerably expanded since 2002. From this, it is finally argued that science communication needs be redefined as a practice of science culture.

This article investigates the topology control problem in the space information network (SIN) using a hierarchical autonomous system (AS) approach. We propose an AS network topology control (AS-TC) algorithm to minimize the time delay in the SIN. Compared with most existing approaches for SIN where either the purely centralized or the purely distributed control method is adopted, the proposed algorithm is a hybrid control method. In order to reduce the cost of control, the control message exchange is constrained among neighboring sub-AS networks. We prove that the proposed algorithm achieve logical k-connectivity on the condition that the original physical topology is k-connectivity. Simulation results validate the theoretic analysis and effectiveness of the AS-TC algorithm.

Purpose: The purpose of this study was to identify the relationship among the factors of self-awareness, other-awareness and communication ability, and how they relate to communication ability in nursing students. Methods: For data collection 237 nursing students completed self-report questionnaires. Data were analyzed using independent t-test, one-way ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Results: Self-awareness, other- awareness and communication ability of the participants showed moderate levels of self-awareness, other-awareness, and communication ability. There were significant positive correlations between self-awareness and communication ability (r=.59, p<.001). and between other-awareness and communication ability (r=.22, p=.001). Social anxiety, private self-awareness, and internal other-awareness were significant factors, which explained about 37% of the variance in communication ability. Conclusion: These findings suggest that a systematic and effective curriculum focused on self-awareness and other-awareness should be developed for nursing students in order to promote their communication ability.

Smartphones have become one of the most prevalent information devices in the current information environment. Although many people use smartphones for communication and information acquisition, these two functions are closely related and cannot be separated. However, many studies have focused on identifying each function of a smartphone independently. There are few studies that investigate the relationships between communication and information acquisition functions on smartphones. This research empirically analyzed and identified the relationships between these two functions of smartphones by conducting a survey. The results of the analysis showed that the activities for information acquisition make differences in communication on a smartphone. People who want to acquire more information tend to use a smartphone for communication purposes. Besides, communication activities on a smartphone also affect the acquisition of information. In addition, communication activities on a smartphone also affect the establishment of interpersonal relationships that lead to the acquisition of more information. From these results, it is identified that communication activities and information acquisition are interrelated when satisfying the information needs of smartphone users. Especially, communication activities on a smartphone positively affect people's information activities and enhance information acquisition.

Including the Qualfication of Staffer required for Commuinication, the National Law of Professional qualification is a basic law for supply with manpower of high growth industry, and it is aiming at perfect the national Policy Concerned improvement for education and training of staff, carrying out of state examination for qualification and getting an occupation or application for special qualification. This law has established a management committee for qualification system in The Ministry of Science and Technique ROK, and authorized competence Minister according to kind of special qualification aiming at getting employment, practical use and courteous treatment in society and economy for national qualification, and also regulated their each official duty. A qualification of staffer required for communication is an administrative measure giving as occupational certificate after some examination for knowledge, technique and faculty in vocational ability to adapt to intrinsic of telecommunication. This certificate has the cause of an attribution of over the sphere of telecommunication, and so it has been originated in international situation, and then some of them is forced by international law, otherwise it be in common use between the nations. The Characteristic and orthodox of communication certificate has been succeded continually in company with development of telecommunication and the appliable field of them is specified, but the sovereign power of nation is approved by ITU that she can extent the applicable position for communication certificate and coordinate the utility of qualification for telecommunication value. Korean telecommunication law excepted the application of communication certificate in public communication field. It is unreasonable and even disobeyed against the theory of communication science and intrinsic of telecommuncation. Therefore it should be corrected immediately and then communication certificate have to accept in the public communication field at all, if so, the application field of communication certificate can have more than useful extenxion such as administration measure should be achieved by the management committee for qualification system in Ministry of Science and Technique and competemce Minister appointed according to special kind of certificate and the administration have to manage by the method and proccess caused by communication science or cooperative system between administration, industry, education and science. And, then, every acquisitor of qualification also has to try to perfect his vocational duty sincerely and to promote each self-realization.

This study aims to unravel the shift in the customary method of disseminating information about the ritual of Perang Topat (literally translated as "rice-cake war") as carried out by the custom community of Kemaliq Lingsar in the West Lombok Regency of Indonesia during the COVID-19 pandemic. Grounded in the ethnography of communication research methodology, this study examines the process of the cultural ritual during the 2020 period of the pandemic and compares it to the ones held in 2018 and 2019 (before the current pandemic). Drawing on findings from observations, in-depth interviews, and documentation, it was revealed that the traditional or custom-oriented community of Kemaliq Lingsar abandoned all three prominently used methods of disseminating the information of the Perang Topat ritual that had been used prior to the pandemic, and that they were replaced by a strategy with solely face-to-face (FTF) interpersonal communication carried out by visiting the homes of the target participants of the cultural event. This method was relevant to the current viral crisis because it enabled the committee to minimize the number of spectators which might potentially violate COVID-19 health protocols. This finding also reinforces the hypothetical statement that interpersonal communication via FTF is effective in disseminating information in a limited manner and empowering the emotional bond between the individuals who share relationships and similar interests. The findings of the present study can be a reference for any events where physical distancing must be strictly imposed and require a limit to the number of participants during the pandemic.

In this study, the effects of the small group collaborative learning on students' achievement, the retention of the achievement, communication anxiety, and science learning motivation were investigated. The aptitude-treatment interaction between the level of students' self-directed learning ability and the intervention was also examined. Two classes (38 students) from an elementary school were respectively assigned to a control group and a treatment group. A self-directed learning ability test, a communication anxiety test, and a science learning motivation test were administered as pretests. The intervention lasted for 8 class periods. After instruction, an achievement test, the communication anxiety test, and the science learning motivation test were administered. An achievement retention test were also administered after four weeks. The results indicated that there were significant treatmentaptitude interaction effects in the achievement test scores and the achievement retention test scores. In the communication anxiety and the science learning motivation, however, any significant difference was not found between the scores of the treatment group and the control group. Educational implications are discussed.

Improvements in wireless sensor network (WSN) technology have resulted in a large number of applications. WSNs have been mainly used for monitoring applications, but they are also applicable to target tracking, health care, and monitoring with multimedia data. Nodes are generally deployed in environments where the exhausted batteries of sensor nodes are difficult to charge or replace. The primary goal of communication protocols in WSNs is to maximize energy efficiency in order to prolong network lifetime. In this paper, various medium access control (MAC) protocols for synchronous/asynchronous and single/multi-channel WSNs are investigated. Single-channel MAC protocols are categorized into synchronous and asynchronous approaches, and the advantages and disadvantages of each protocol are presented. The different features required in multi-channel WSNs compared to single-channel WSNs are also investigated, and surveys on multi-channel MAC protocols proposed for WSNs are provided. Then, existing broadcast schemes in such MAC protocols and efficient multi-hop broadcast protocols proposed for WSNs are provided. The limitations and challenges in many communication protocols according to this survey are pointed out, which will help future researches on the design of communication protocols for WSNs.
