베트남 북부 산악지형에 거주하는 소수 부족민들의 생계개선이 베트남 정부의 정책적인 지원 사업에도 불구하고 현재까지 뚜렷한 성과를 내지 못하는 것으로 알려져 왔다. 특히 지속가능한 개발 및 인적자원개발을 목표로 하고 있는 베트남 경제사회개발정책(2011~2020)의 하위전략인 신농촌 개발정책(New Rural Development)에 의한 사업들이 적절히 수행되고 있는지 의문이 대두되었다. 한편, 베트남 라오까이성 행복프로그램은 한국 코이카 재원으로 새마을운동 경험과 정신을 바탕으로 설계되었으며 심각한 빈곤상태에 있는 성내 8개 소수부족민 마을에 마을특성과 주민 의견이 반영된 개발계획을 수립하고 계획실행의 주체인 마을주민들과 현장 공무원에게 다양한 훈련 사업들을 제공하였다. 본 연구는 생계개선에 대한 이론 고찰과 함께 한국 및 베트남의 농촌개발 경험사례 분석을 바탕으로 프로그램의 다양한 역량강화 사업들이 8개 소수부족 주민들의 의식변화와 생계자산 향상에 어떠한 영향을 끼쳤는지 알아보았다. 본 연구결과는 프로그램에서 제공한 다양한 역량강화 훈련들이 주민의식의 긍정적인 변화와 소수 부족민들의 생계자산에 대하여 상당한 만족도를 가져왔는바, 신농촌 개발정책은 직접자재 위주의 지원을 줄이는 대신 주민들의 자신감 고취를 위한 주민의식 교육과 주민들의 생계활동 능력향상을 위한 다양한 훈련 사업을 확대해야 함을 보여준다.

This study developed and applied the teacher education model and its principles for science classes using Virtual and Augmented Reality (VR/AR) content and analyzed preservice elementary teachers' feedback on the teacher education model and the changes in their perceptions as to the use of VR/AR content. First, existing Technological Pedagogical Content Knowledge (TPACK) teacher education models and prior studies on the use of the VR/AR contents were reviewed to derive the teacher education model to cultivate the VR/AR-TPACK and set the key principles for each of its stages. The developed teacher education model has five stages: exploration, mapping, collaborative design, practice, and reflection. Second, to examine the appropriateness of the model's five stages and principles, we applied it within the regular course of instruction at the university of education, which was attended by 25 preservice elementary teachers. This study collected data from surveys on the perception of the usage of VR/AR contents before and after the course, as well as the group lesson plans prepared by the preservice teachers, and their feedback on the teacher education model. The feedback on the teacher education model and the survey conducted by the preservice teachers before and after the course were analyzed through open coding and categorization. As a result, most preservice teachers expressed positive opinions about the activities and experiences at each stage of the implementation of the teacher education model. Perceptions related to the usage of the VR/AR content changed in three aspects: first, the vague positive perception of the VR/AR content has changed to a positive perception based on specific educational affordance. Second, they recognized the need for preparedness by anticipating potential problems associated with the use of the VR/AR content. Third, they came to view the VR/AR contents as a useful instructional resource that the teachers could use. Based on these results, we discussed the implications for the VR/AR-TPACK teacher education model and assessed the limitations of the research.

In this study, we aimed to understand the public opinion on COVID-19 vaccine. To achieve the goal, we analyzed COVID-19 vaccine-related Twitter posts. 45,413 tweets posted from March 16, 2020 to March 15, 2021 including COVID-19 vaccine names as keywords were collected. The 12 vaccine names used for data collection included 'Pfizer', 'AstraZeneca', 'Modena', 'Jansen', 'NovaVax', 'Sinopharm', 'SinoVac', 'Sputnik V', 'Bharat', 'KhanSino', 'Chumakov', and 'VECTOR' in the order of the number of collected posts. The collected posts were analyzed manually and automatedly through keyword analysis, sentiment analysis, and topic modeling to understand the opinions for the investigated vaccines. According to the results, there were generally more negative posts about vaccines than positive posts. Anxiety about the aftereffects of vaccination and distrust in the efficacy of vaccines were identified as major negative factors for vaccines. On the contrary, the anticipation for the suppression of the spread of coronavirus following vaccination was identified as a positive social factor for vaccines. Different from previous studies that investigated opinions about COVID-19 vaccines through mass media data such as news articles, this study explores opinions of social media users using keyword analysis, sentiment analysis, and topic modeling. In addition, the results of this study can be used by governmental institutions for making policies to promote vaccination reflecting the social atmosphere.

This study discusses on the influential factors of satisfaction in communication by focusing on the political communication phenomenon that is revealed in our society. The acts of political communication and its communication satisfaction are examined by exploring individuals' political inclination and their media usage which are the main influential factors of political communication. An interview survey was conducted on a thousand adults over the age of nineteen who are residing in sixteen cities and provinces nationwide. As a result, a high rate of online media usage was observed among people with progressive political inclination. It showed that the political communication acts of 'writing/communicating' which indicates ons actively posting their personal opinions, has a positive influence on communication satisfaction. On the other hand, the usage of offline media was dominant over people with conservative and neutral political inclination. A passive act of 'reading/watching,' which is to observe other people's opinions, was shown by most of the interviewees. Therefore, it was able to discuss that in order for a harmonious flow of political communication among our society, the understanding of citizens' political characteristic must be preceded and the differentiated political communication using media must be raised accordingly.

The regulation of media concentration which is provided in the German Interstate Treaty on Broadcasting (RStV) is part of the rules forming the "positive broadcasting order" required by German Constitutional Law. This control ensures that the diversity of viewpoints can be articulated to the public. Broadcasting must operate independently from the state and from particular social groups if it is to be a genuine service to the public. One risk of economic competition in the media is a tendency towards the concentration of business enterprises. Moreover, economic competition is no guarantee for journalistic diversity. The aim of balanced diversity in the broadcasting sector can only be pursued by creating conditions under which different voices obtain the chance to be heard in an equitable manner. Within the framework of the meaning of section 26, it shall be assumed that there is a predominant impact on public opinion if the programs attributable to one company reach an annual audience share of 30 percent. The same shall apply if the company reaches an audience share of 25 percent and holds a dominant position in a related media-market or an overall assessment of its activities in television. The restriction of audience shares has limits such as that the audience shares of news programs and education and entertainment programs are pooled. Therefore, there is a vagueness about the productivity of different program branches.
