In this paper, a strategy of cooperation activities was conducted to analyze on the impact of what effect appears in teacher training. We classified with satisfaction, effectiveness and academic achievement as effects of teacher training. We were divided into three groups that are cooperative-reflection activity group using the SNS, self-reflection activity group and general training group. Depending on the type of reflection activity, we have one-way ANOVA analysis for the effectiveness of teacher training. By the results of the analysis, we found to have a positive impact that cooperative reflection activity group were more an academic achievement, satisfaction and effectiveness of training. Accordingly, we have found the SNS-based collaborative reflection activity is very effective in teacher training.

지금, 세계는 바야흐로 'Social Network Service(이하 SNS)의 시대' 이다. SNS란 '일련의 관계에 의해 모인 사람들 간의 관계망을 특정 체계를 통해 대중에게 제공하는 것' 이라고 할 수 있다. 과거 향우회, 동문회처럼 오프라인에서 존재했던 이러한 관계망이 온라인으로 도입된 것이 현재 SNS라고 일컫는 서비스이다. SNS가 큰 인기를 끌고 정보 사회가 발전함에 따라 SNS의 서비스와 형태도 점차 다양해져 왔다. 특히나 그림 영상 등의 시각적인 요소를 사용한 의사소통과 정보의 공유가 과거 그 어떤 매체보다도 손쉽고 빠르게 이루어지고 있다. 인간의 거의 모든 문화 사회적 활동에 컴퓨터가 기반이 됨으로써, 우리는 점차 텍스트, 사진, 영화, 음악, 가상환경 등과 같은 문화 데이터와 더욱 밀접한 관계에 놓이게 되었으며 이것은 SNS에서도 예외가 아니다. 우리는 더 이상 컴퓨터를 마주하는 것이 아니라 디지털 형식으로 기호화된 문화와 마주하고 있으며, 그 중심에는 시각적인 요소들, 즉 '이미지'가 있다. 이러한 점에 착안하여 본 연구는 'SNS'와 그 이미지들의 특성에 대한 이해를 선행한 뒤, 최근 국내에서 가장 활발한 성장세를 나타내고 있는 SNS인 미투데이 페이스북 이상의 두 서비스의 사례를 분석할 것이다. SNS의 이미지의 정체성, 이미지 표현의 특징과 양상이 어떠한지를 분석하고 SNS에서 사용되는 이미지와 그 의미를 보다 심층적인 관점에서 이해해 보는 것은 SNS를 중심으로 형성되어 있는 관련 업계와 학계에 유의미한 내용을 제공할 것으로 기대된다.

Predicting a box office gross in the film industry is an important goal. Many works have analyzed the elements of a film making. Previous studies have suggested several methods for predicting box office such as a model for distinguishing people's reactions by using a sentiment analysis, a study on the period of influence of word-of-mouth effect through SNS. These works discover that a word of mouth (WOM) effect through SNS influences customers' choice of movies. Therefore, this study analyzes correlations between a box office gross and a ratio of people reaction to a certain movie by extracting their feedback on the film from before and after of the film opening. In this work, people's reactions to the movie are categorized into positive, neutral, and negative opinions by employing sentiment analysis. In order to proceed the research analyses in this work, North American tweets are collected between March 2011 and August 2012. There is no correlation for each analysis that has been conducted in this work, hereby rate of tweets before and after opening of movies does not have relationship between a box office gross.

The purpose of this study was to understand changes in domestic forest policy and social perception of forests from a macro perspective using big data analysis of news articles and editorials. A total of 13,570 'forest' related data were collected from metropolitan and economic journals from 1946-2017 using keyword and CONCOR (Convergence of iterated Correlations) analysis. First, we found the percentage of articles and editorials using the keyword 'forest'increased overall. Second, news data on 'forest' in the field of reporting was concentrated in the "social" sector during the first period (1946-1966), followed by forest-related issues expanding to various fields from the second (1967-1972) to fifth (1988-1997) periods, then toward the "culture" sector in the sixth (1998-2007) and "politics" after the seventh (2008-2017) period. Third, we found changes in the policy paradigm over time significantly changed social awareness. In the first and second periods, people experienced livelihood issues rather than forest greening or forest protection policy and expanded their awareness of planned and scientific afforestation (third) to environmental protection (fourth) and ecological perspectives (sixth to seventh). The key outcome of our analysis was leveraging news big data that reflected polices on forests and public social perception To further derive future social issues,more in-depth analysis of public discourse and perception will be possible using textual big data and GDP of various social network services (SNS), such as combining blogs and YouTube.

This study attempted to suggest a direction for better services by analyzing correlations among usage patterns, perception, professionalism and satisfaction with nail services given through social media and commerce. For this, a questionnaire survey was performed against women in their 10-50s in Daejeon, Sejong and Chungcheong from October 1 to 20, 2021. A total of 326 copies were used for final analysis The collected data were analyzed, using SPSS 27.0. The results found the followings: As the treatments and products were more specialized, the respondents were more satisfied with services, convenience, treatments and products. Therefore, it is anticipated that the study results would available as basic data which are needed in analyzing correlations among usage patterns, perception, professionalism and satisfaction with nail services given through social media and commerce.

The purpose of this paper is a study of survey about teachers' attitude and recognition of education using newest information technology such as s-learning, social network and Web 3.0. We researched for elementary school teachers about recognition of the newest IT trend, educational necessity and effect of the newest IT. As a result, recognition and understanding of the newest IT is low but teachers think that effect of education using the newest IT is very high. Moreover, they have a lot of will for using the newest IT devices and training about the newest IT. However, it shows that they are diffident of taking charge of the newest IT and teaching for students using it. Also, the results showed different tendency as generations. This study would be a important role for deciding on direction of informatics education for 21C.

Recently, IM(Instant Messenger) of KakaoTalk is being used on smart devices such as smartphones. Because IM service can carry user and/or suspector's various information including life style, geographical position, psychology and crime history, forensic analysis on IM service is desirable. But, forensic analysis for KakaoTalk is not well studied yet. This paper studies a proper forensic method for KakaoTalks, finds artifacts location, reconstruct the list of contacts and the chronology of the messages that have been exchanged by users. Proposed methodology and analyzed information can provide a basic platform for forensic tool.

VoIP(Voice over IP)는 패킷교환망을 통해 음성통신을 제공하는 기술이다. 초기의 VoIP에서는 사용상 제약조건과 불편함 때문에 사업모델이 성립하지 못하였다. 무선 광대역통신이 가능해지고, 멀티미디어 서비스에 적합하게 진화함에 따라 VoIP에서 무선접속기술을 이용한 Mobile VoIP서비스를 제공하고 있다. Mobile VoIP의 편리성으로 인하여 VoIP에서 새로운 사업모델이 창출되었고, 웹 2.0과 Mobile 인터넷전화의 결합에 의해 SNS(Social Network Service)으로 서비스가 확장되었다. 이로 인해 많은 서비스 제공자가 발생하였고, 이 서비스 제공 사업자는 크게 이동통신사업자, 소프트웨어 서비스 사업자, 가상이동통신사업자, 그리고 별정 사업자로 분류된다. 4가지의 서비스 제공 사업자는 각각 사업모델이 차별화 되어 있다. 본 논문에서는 Mobile 인터넷전화 기술동향을 살펴보고 서비스 동향을 분석한다. 그리고 Mobile 인터넷전화의 서비스 제공사업자의 차별화된 사업모델을 분석한다.
