최근 초고속 인터넷 망의 확대와 통신 위성의 개발 보급에 힘입어 정보의 디지털화가 가속되면서 방송과 통신기술이 융합되고 그 경계가 점차 모호해지고 있다. 이에 따라 다양한 멀티미디어에 대한 요구가 날로 늘어나고 있으며, 각종 방송 서비스에 대한 시청자의 참여가 활발하다. 증가하는 시청자의 요구를 수용하고 보다 나은 서비스를 제공하기 위해 2010년경에는 지상파 아날로그 방송이 모두 디지털화 될 예정이며, 그 이후에는 입체TV를 비롯한 실감방송이 서비스될 예정이다. 이러한 시대적 흐름에 발맞춰 본 논문에서는 실감방송과 차세대 실감형 미디어인 다시점 비디오 기술에 대해 살펴보고자 한다.

We are presenting an overview of a R&D trend on dye-sensitized solar cells and organic polymer solar cells, which are classified into a next-generation solar cell, and the perspective on their hybridization technology. When considering the competition with inorganic material-base solar cells, especially, these next-generation solar cells need a new hybridization technology, even though it is still at the initial stage. The fusion and hybridization of them will be not only attractive in a new application, but also promising to expect significant progresses in the near future for successful R&D.

본 논문에서는 지방자치단체(지자체)에서 관리하는 다양한 예·경보시스템들이 별도의 서버로 관리되어 다원화 운영으로 복잡할 뿐만 아니라 제공하는 정보의 내용과 범위도 통일되지 않았던 문제점과 중앙 정부에서 재난정보 전달에 대한 결과 정보를 실시간으로 확인이 어려웠던 문제점을 해결하기 위한 방안 및 시스템에 대해서 제안한다. 제안하는 차세대 통합 예·경보 플랫폼은 웹서비스 형태로 접속하여 부여된 권한에 따라 재난정보를 한 번의 클릭을 통해 다양한 매체로 전달할 수 있을 뿐만 아니라, 재난정보 전달에 대한 결과도 실시간으로 확인 가능한 장점을 지니고 있다. 본 논문에서는 국내 예·경보시스템의 현황을 살펴보고 이를 기반으로 차세대 통합 예·경보 플랫폼의 구조 및 전달하는 재난정보 프로파일을 제안하고 이를 통해 기존 예·경보 시스템을 통합 연동 및 관리하는 방안에 대해 설명한다.

In accordance with evolution of next-generation mobile Internet, 2G, 3G, 4G, and B4G mobile communication wireless access networks will be co-existed and service providers will be merged as an integrated service provider. In addition, multiple virtual service operators will appear. In order to provide complicated unified-services, in the future Internet, wireless network virtualization where network resource is shared by various service operators is necessary. Therefore, in this paper, we investigate network architectures and virtualization scenarios for wireless access network virtualization where various wireless access technologies are flexibly operated by multiple service providers over next-generation wireless access networks. We expect that the virtualization scenario and network architecture yielded from this study can play a role as a basis for development of wireless access network virtualization algorithms.

The purpose of this study is to provide basic data for developing effective intervention methods to improve the quality of life by identifying the factors that affect the quality of life of the baby boomers. A descriptive survey research was conducted with the research subjects, 145 baby boomer women who lived in Island J from June 1 to June 30, 2018. The analysis of quality of life had positive correlations with health condition, family relationship satisfaction, retirement preparedness, age, aging anxiety, and showed negative correlations with family relationship satisfaction, and aging anxiety. Therefore, this research is expected to provide useful materials to develop efficient mediation programs in various areas for positive preparation for the golden age and improved family relationship.

The purpose of this study was to verify the moderating effects of the stress coping styles on the effects of internet addiction on the self-esteem of the 2030 generation during the Covid19 period. The 762 samples were selected through an online survey, and the collected data were conducted using the SPSS WIN26.0 program for frequency analysis, correlation analysis, and hierarchical regression analysis. As a result of the analysis, Internet addiction had a negative effect on self-esteem, and only seeking social support among the four sub-factors of stress response served as a moderator variable in the relationship between Internet addiction and self-esteem. Based on the results, the followings were suggested: expansion of research subjects regarding Internet addiction and interdisciplinary convergence study, providing universal provision of stress coping management programs, building a community at the local level, and discovery and reinforcing variables that offset the negative role of self-esteem of 2030 generations.

This study entailed an investigation of a tensile stress measurement method for prestressed concrete (PSC) tendons by utilizing external magnetization. The target of this study are PS structures that have been constructed and in use. An optimal external magnetization based elasto-magnetic (EM) sensor was designed using finite element analysis considering various factors, such as coil arrangement and size, that could influence the PS tendons inside the PSC girder. The residual tensile stress resulting from the external magnetization of the girder was then determined. Further, theoretical verification was performed using the numerical and material data used in the finite element analysis for sensor design. The calculated values of strength of magnetization at the target location were matched with the finite element analysis results. Thus, the designed sensor and the feasibility of magnetizing the tendons inside the PSC I-girder using an EM sensor were validated.

Currently, South Korea is grappling with a paradoxical situation characterized by simultaneous labor shortages and job shortages. Within this context, retirees are citing conflicts with supervisors/colleagues and dissatisfaction with organizational culture as the primary reasons for their departure, with these issues disproportionately affecting the MZ generation. In response, scholars have conducted preliminary studies to understand the relationships between organizational culture and other variables specifically concerning the MZ generation. However, most of these studies are based on a unified theory of the MZ generation, failing to satisfy the practical demands for distinguishing between Generations M and Z. Therefore, this research aims to explore the differences in variable relationships between these two groups within the hospitality industry. Surveys were conducted among 170 individuals from Generation M and 110 from Generation Z, and the data were analyzed using AMOS structural equation modeling. The analysis confirmed that both hierarchical culture and generational conflict significantly define relationships across all generations, with generational conflict adversely affecting organizational commitment. Additionally, while a relationship-oriented culture negatively impacts generational conflict for Generation M, no such effect was observed for Generation Z. This study successfully identifies the differential impacts between Generation M and Generation Z.
