According to Mead's (1934) symbolic interaction theory, social roles are learned through interaction and experiences in everyday life. Over time, these rules of behavior become internalized and serve to structure one's actions accordingly. Ultimately, these rules provide us with a powerful means of controlling our actions, and in time, they define our identity. Transforming the socialization process is one's conscious interpretation of stimuli through the use of symbols. Furthermore, society's perceptual processes can be shaped by the symbols we learn. The meaning of symbols can be learned from a variety of social influences, one of which may be mediated messages and advertising. This paper attempts to establish a link between media exposure and one's perception of social reality regarding character judgments made of unknown others based on the target's product or brand usage. Using magazine advertisements for fictitious products, the experiment herein seeks to establish two fundamental goals: 1) to determine if perceptions can be manipulated via association with companion symbolic elements: and 2) to detect whether television exposure is a moderating factor. Respondents were asked their perceptions of both product quality and of product users.

The OTT service that provides multimedia video has spread over the Internet for terminals with a variety of resolutions. The terminals are in communication via a networks such as 3G, LTE, VDSL, ADSL. The service of the network has been increased for a variety of terminals giving rise to the need for a new way of encoding multimedia is increasing. SVC is an encoding technique optimized for OTT services. We proposed an efficient multimedia management system for the SVC encoded multimedia data. The I/O trace was generated using a zipf distribution, and were comparatively evaluated for performance with the existing system.

Results of the analysis have revealed that the students were basically divided into three groups depending on goodness-of-fit index and latent class division factor. Type 1 was regarded as a low dependence group (50.1%) with all low indexes while Type 2 was classified as a high dependence group (10.7%) with all high indexes. As for Type 3, it was titled intermediate dependence group (39.2%) for the indexes showed a low-to-moderate movement. A multinomial logistic regression analysis was carried out to forecast smart phone dependence characteristics and as a consequence, when the high dependence group was compared to the intermediate dependence group, as self-esteem and peer attachment increased and deceased respectively, a chance of one being classified into the intermediate dependence group rose. In an investigation to compare the high dependence group with the low dependence group, it was confirmed that the greater the self-esteem, the shorter the peer socializing time, the lower the neglect degree and the lower the peer attachment, a chance for one belonging to the low dependence group increased. This study also offered implications, limits and directions in follow-up research.

Korea is rapidly becoming a multicultural society in recent years, and the number of multicultural families in 2015 exceeds 3.5% and 800,000. Also, as international marriage rate exceeds 10% by 2016, the number of multicultural families is expected to steadily increase. This study is a design of a metadata application profile as part of the foundation for providing learning resources and content tailored to the needs and preferences of married immigrant women and multicultural family members who need to adapt to Korean society. In order to verify the necessity of the research, we conducted an in-depth interview by screening consumer groups, and analyzed the relevant international and Korean national standards as de-jure standards for the design of metadata standard profiles. Then, we analyzed the contents characteristics for multicultural members, and organized the necessary metadata elements into profiles. We defined the mandatory/optional conditions to reflect the needs of content providers. This study is meaningful in that the study analyzes the educational needs of married immigrant women and presents the necessary metadata standards to develop and service effective educational content, such as korean-to-korean conversion system, personalized learning contents recommendation service, and learning management system.

The purpose of this study was to classify the latent profiles of elementary school teachers' job stress and to explore the effects of the relative variables to determine these classifications. In addition, the differences in the teacher-student relationship and parental involvement in school based on the classification were discussed. Data from 709 elementary school teachers who participated in the 11th wave of the Panel Study on Korean Children in 2018 were analyzed by Latent Profile Analysis (LPA). The findings can be summarized as follows. First, four subgroups could be defined according to the elementary school teachers' job stress: low-level job stress group, mid-level job stress group, mid-level administrative work stress group, and mid-level relationship and guidance stress group. Second, the final education and average time to work were significant determinants of the latent groups. Third, teacher-student conflict and parental involvement in school showed differences between the subgroups. Specifically, the mid-level relationship and guidance stress group reported the highest conflict level with children and the lowest parental involvement in school. These findings suggest promoting relief and preventative training programs for elementary school teachers to overcome various job stress.

This study aims to identify subgroups of ageism among young adults of age 20-39, and to examine its relationship to perceptions of generational conflict and elderly welfare policy. Latent Profile Analysis(LPA) was applied on the data 'Survey on Age Integration and Generational Integration', which was executed by institute for Age Integration Researchof Ewha Womans university, and descriptive statistics and cross-tabulation analysis were performed to examine the socio-demographic characteristics of each subgroup. Then, regression analysis was performed to observe the effect of the subgroups on the perceptions of generational conflict and elderly welfare policy. The results are as follows. The resulting subgroups of ageism among young adults were 'compound perception on aging and active age discrimination', 'medium-level aging anxiety and passive age discrimination', and 'low-level aging anxiety and beyond age discrimination'. Subgroups of ageism affected both perceptions of generational conflict and elderly welfare policy, whereas social support only affected perception of elderly welfare policy. Based on the results, political implications, such as activation of education on perception on aging, expansion of generational exchange for age integration, and renewal of social atmosphere for intergenerational coexistence, which will promote social integration

최근 스마트폰의 폭팔적인 증가와 함께 사용 환경개선도 이루어 지고 있다. 또한 Wi-Fi 존의 증가와 LTE같은 빠른 네트워크 환경은 사용자 중심의 수 많은 앱을 탄생시키고 있다. 안드로이드는 애플의 iOS와는 다른 오픈소스 정책으로 플랫폼 소스가 공개되어 있어 많은 개발자가 쉽게 접근이 가능하다. 그러나 안드로이드는 앱(App) 검증 체계가 미흡하기 때문에 악성코드 등으로 인한 위협요소가 존재하고 있다. 또한 파일 시스템은 임의적 접근제어방식으로 공격자가 취약점을 통해 관리자 권한을 얻어 시스템 자원을 제어할 수 있기 때문에 위협요소가 다분하다. 본 논문에서는 스마트폰 앱이 호출하는 시스템 API 및 네트워크 자원사용 패턴을 분석하여 부정 앱을 차단하는 방법을 제안하였다. 제안 방법으로 실험한 결과 API호출 빈도 및 자원 사용률이 최소 기준치 이하로 검출된 경우를 제외한 평가대상은 모두 검출하여 보안성 강화에 효과적인 것으로 실험을 통하여 검증하였다.

In this paper, we proposed service security model and remote management service on OSGi computing environment. The model is used to make access control decisions like permission-based security inside the java2 platform. In model, policies are defined using a flat text file and include bundles. It method granted flexibility and extendability of access control of bundles and services. Also, we proposed service architecture efficiently for remote management service.
