The purpose of this study was to investigate the interaction and effects of shame and parent-child communication on children and early adolescents' peer pressure. The subjects of this study were 359 children and early adolescents from 5th grade in elementary school to 2nd grade in middle school (187 boys, and 172 girls) in Daejeon city. The results of this research indicated that gender and age played a significant role on the effects of shame and parent-child communication on peer pressure. Open communication with mothers showed a positive relationship with boys' peer pressure, whereas open communication with father showed a negative relationship with boys' peer pressure. The interaction effects of shame and open-communication with fathers and mothers worked differently on peer pressure across gender and age. Interaction effects of shame and open communication with fathers and mothers were significant for boys, but not for girls. Interaction effect of shame and open communication with mothers was significant for children and adolescents.

Automatic modulation classification is a critical algorithm for non-cooperative communication systems. This paper addresses the challenging problem of closed-set and open-set signal modulation classification in complex channels. We propose a novel approach that incorporates a self-learning filter and center-loss in Deep Residual Shrinking Networks (DRSN) for closed-set modulation classification, and the Opendistance method for open-set modulation classification. Our approach achieves better performance than existing methods in both closed-set and open-set recognition. In closed-set recognition, the self-learning filter and center-loss combination improves recognition performance, with a maximum accuracy of over 92.18%. In open-set recognition, the use of a self-learning filter and center-loss provide an effective feature vector for open-set recognition, and the Opendistance method outperforms SoftMax and OpenMax in F1 scores and mean average accuracy under high openness. Overall, our proposed approach demonstrates promising results for automatic modulation classification, providing better performance in non-cooperative communication systems.

인터넷 환경은 통신 개체간에 보안 통신을 설정하기 위한 부가적인 메카니즘이 필요하다. 통신 개체들은 데이터의 무결성을 보장하는 암호화/복호화, 보안 채널을 통해 데이터를 송수신한다. 또한, 보안 통신 프로토콜을 통한 상호 인증이 지원 되야 한다. SSL/TLS는 통신 개체간의 안전한 통신 채널을 생성하여 데이터 송수신을 제공하는 프로토콜이다. TLS를 구현한 OpenSSL이 활발히 사용되고 안정성과 성능이 입증되었지만, 크기가 크며, 툴킷 형태의 사용에 어려움이 있다. 이에 본 논문은 기존 OpenSSL의 안정성은 유지하면서 라이브러리의 수정 작업을 통하여 개발자들이 쉽고 간편하게 사용할 수 있는 보안 통신 API 설계, 구현하였다. 구현된 API 사용하여 보안 통신을 지원하는 클라이언트i서버 사례를 통하여 실제 적용한 후 결과를 확인한다.

Using the network analysis method, this study investigates the communication structure of Open Data on the Twitter sphere. It addresses the communication path by mapping influential activities and comparing the contents of tweets about Open Data. In the years 2015 and 2016, the NodeXL software was applied to collect tweets from the Twitter network, containing the term "opendata". The structural patterns of social media communication were analyzed through several network characteristics. The results indicate that the most common activities on the Twitter network are related to the subjects such as new applications and new technologies in Open Data. The study is the first to focus on the structural and informational pattern of Open Data based on social network analysis and content analysis. It will help researchers, activists, and policy-makers to come up with a major realization of the pattern of Open Data through Twitter.

Objective: This study aimed to examine the moderating effect of elementary school students' perception of open communication with their parents in relationship to smartphone dependency and school adjustment. Methods: Participants included 300 fifth and sixth graders attending P and A elementary schools in Gyeonggi Province. Descriptive analysis, correlation analysis, and hierarchical regression analysis were performed to analyze data. The level of significance was set at p < .05 for all analyses. Results: The results of the present study are as follows: First, male students showed higher levels of smartphone dependency than female students, and students' smartphone dependency increased according to age. The students' smartphone dependency was negatively associated with their school adjustment and their perception of open communication with their parents. Second, the students' perception of open communication with their fathers was found to moderate the relationship between smartphone dependency and school adjustment. Conclusion/Implications: These findings indicate that open communication between parents and their elementary school-aged children can buffer the adverse effects of smartphone dependency on school adjustment. This study provides implications for parent education and counseling to improve parent-child communication and subsequently build strong, positive family relationships.

The purpose of this study is to find out significant factors which have effects on the communition styles and adolescents' satisfaction in communication through the investigation of the communication styles between adolescents and mothers and the degree of adolescents' satisfaction in communication. The subjects of this study were 44 high school students in Seoul Statistical methods emploid to analyze the data were percentage, frequency, mean, X2-test, F-test and multiple regression. The results were as follows; 1) The communication styles between adolescents and mothers were divided into 4 grpups, and the proportion of these 4 groups were mutual open style 40.3% mutual closed style 34.5%, adolescent closed-mother open style 13.1% and adolescent open-mother closed style 12.2%. 2) Factors influencing the communication styles were sex (p<.001), communication time (p<.001) and atomosphere of families(p<.001). 3) The degree of adolescents' satisfaction in communication were significantly different depending on the communication style (p<.001), sex (p<.001), communication time (p<.001) educational level of father (p<.05), employment status of mother (p<.05), atomosphere of famlies (p<.001) and economic condition of families (p<.001). 4) The most significant variables influencing the degree of adolescents' satisfaction were communication styles and the atomosphere of families. The groups using open communication styles were more satisfied with their communication that the groups using closed communication styles. The female adolescents were more sensitively influenced than male adolescents with these two variables.

The purpose of this study was to investigate the role of anxiety in mediating the influence of family of origin characteristics on subsequent relationship processes. Using Bowenian theory as a foundation, this study examined the causal relationships among gender, religion, family of origin-fusion, intimacy, intimidation, personal-trait-anxiety, couple open communication and relationship satisfaction. Results of the path analysis indicated that: (a) gender, religion, family of origin-fusion, and family of origin-intimidation were directly related to personal-trait-anxiety, (b) personal-trait-anxiety was directly related to couple open communication and not related to relationship satisfaction, (c) couple open communication was directly related to relationship satisfaction, and (d) family of origin factors were not directly related to couple open communication and relationship satisfaction; rather, as it was expected, indirect associations, through the mediation of anxiety, were found. The results generally support Bowen's intergenerational process theory, which asserts that anxiety is the mediator of the process. Limitations of the current study and suggestions for further research were discussed.
