In response to the challenges posed by a super-aged society, local authorities are conducting educational programs on smartphone usage tailored for the elderly. However, obstacles such as the limitations of one-to-many education and suboptimal learning outcomes for the elderly have hindered the efficacy of smartphone education. This study suggests an educational service intended for direct application in offline settings, considering the identified problems. Through the utilization of generative AI, the proposed app identifies specific challenges encountered by users during actual smartphone use, offering personalized exercises to facilitate customized and repetitive learning experiences for individual users. When integrated with existing local government education initiatives, this app is anticipated to enhance the efficiency of smartphone education by providing personalized, one-on-one training that is efficient in terms of time and content.

It has able to be possible that expression and store visual image from analog to digital without picture quality damaged via improvement of video compression technology. And also, It is possible to broadcasting digital image via transmission of digital image on MPEG-2 standardization. for this reason, the broadcasting business owners have converted broadcasting service from analog to digital. But, local SO(System Operator) has a difficult point which secure HD(High Definition) broadcasting program. In this paper, we designed and implemented Scheduling System for MPEG-2 Digital broadcasting which gather HD broadcasting program from major broadcasting business owners(as like MBC, KBS, SBS, etc) and broadcast them.

Today, each broadcasting station makes the best use of CG (computer Graphics), which is the latest technology in election broadcasting, and competes to attract the eyes of viewers. This paper investigated the history of CG technology and design transitions in election ballot counting broadcasts from the perspective of CG designers. From the 1980s, when computer-based election ballot counting began, to the full-scale use of virtual studios, the image and technology produced by CG while watching the ballot-counting broadcast video of general elections, presidential elections, and local elections. We analyzed the utilization from various angles. In Korea, we started with the EDDS (Election Data Display System) developed in-house, created a database using a computer, and introduced manual animation CG every day from that time. After that, broadcasting stations focused on diverse and gorgeous CG image competition, and CG images were expanded from 2D to 3D while technology and design developed together. From 1985 to 1992, Korean broadcasting can be seen as a transitional period in which the image changes due to the emphasis on information power while utilizing digital technology.

This research aims to provide empirical basic data for the development of local communities through the establishment of efficient strategies for the formation of positive relations between the club and the region through the Creation of Shared Value (CSV) activities. We come up with the results of this study to show that CSV, social problem orientation, and core competency utilization affect the team trust of local community, and that CSV, long-term orientation, social problem orientation and core competency utilization affect community identification. The research should enhance the value of professional sports teams that promote their own path to self-sustaining as a single independent business area, and identify their trust through CSV activities for co-prosperity with their local communities, and thus their relationship with the community. Therefore, various strategies and efforts will ultimately increase the team trust and community identity of local residents in professional volleyball teams, while at the same time gaining positive effects on professional volleyball teams.

최근 게릴라성 폭우등 지구 환경의 변화로 인하여 국지적 재난이 빈번히 발생하고 있는 상황이다. 국지적 재난 상황을 일반 국민에게 신속히 전파하는 방법으로 방송매체를 많이 이용하고 있으며 특히 디지털 방송과 같은 매체는 이동중이나 정전 그리고 데이터망이 유실된 상태에서도, 방송망을 활용한 재난방송 시스템이 필요한 상태이다. 이러한 점을 고려하여 DMB가 재난 방송에 적합한 매체로 인식이 되고 있다. 그러나 현재 DMB재난방송시스템은 광역 단위의 재난 상황시에만 DMB를 이용하여 상황전파가 이루어 지고 있으므로 국지적 재난상황과 같이 지역 맞춤형 재난방송을 통하여 재난방송의 신뢰성을 높이고 광범위한 정보가 아니라 지역단위의 필요한 정보를 제공하여 국민의 재산과 생명을 보호하는데 국지적 DMB 방송망이 적극 활용 되도록 재난경보방송시스템을 연구하였다.

A specific anthropomorphic mannequin (SAM) model was used to investigate the relation between local specific absorption rate (SAR) and head size. The model was scaled to 80 to 100% sized models at intervals of 5%. We assumed that the shell of the SAM model has the same properties as the head-equivalent tissue. Five handsets with a monopole antenna operating at 835 MHz were placed in the approximate cheek position against the scaled SAM models. The handsets had different antenna lengths, antenna positions, body sizes, and external materials. SAR distributions in the scaled SAM models were computed using the finite-difference time-domain method. We found that a larger head causes a distinct increase in the spatial peak 1-voxel SAR, while head size did not significantly change the peak 1-g averaged-SAR and 10-g averaged-SAR values for the same power level delivered to the antenna.

In this paper, we propose the audio watermarking algorithm based on the critical band of HAS(human auditory system) without audibly affecting the quality of the watermarked audio and implement the detecting algorithm on the BSS(broadcast synchronizing system) for testing the proposed algorithm. According to the audio quality test, the SNR(signal to noise ratio) of the watermarked audio objectively is 66dB above. In the robustness test, the proposed algorithm can detect the watermark more than $90\%$ from various compression(MP3, AAC), A/D and D/A conversions, sampling rate conversions and especially asynchronizing attacks. The BSS automatically switches the programs between the key station and the local station in broadcasting system. The result of reliability test of implemented system by using the real broadcasting audio has no false positive error during 30 days. Because of detecting once processing per 0.5 second, we can judge that the false positive error does not occur.

This paper describe an interactive video object segmentation tool which can be used to generate MPEG-4 video object planes for multimedia broadcasting and enables content based functionalities. In order to apply these functionalities, each frame of video sequence should be represented in terms of video objects. Semiautomatic segmentation can be thought of as a user-assisted segmentation technique. A user can initially mark objects of interest around the real object boundaries. Then the user-guided and selected objects are continuously separated from the unselected areas though time evolution in the image sequences. We proposed method shows very promising result and this encourages the development of object based video editing system.

The Korea terrestrial broadcasting has TV and Radio, DMB. The TV broadcasting was converted from the analogue method to the digital method at the end of 2012. However the radio broadcasting is still in analogue method. The introduction of digital radio technology will bring many benefits such as high-quality of sound, various additional services and increase of efficiency in frequency utilization. In many countries, the radio broadcasting is been servicing in digital method. The discussion was begun on this year for the introduction of digital radio technology in Korea. So, to prepare against introduction of DAB system among digital radio technology, this paper proposes channel allocation method for each local radio broadcasting and the composition of national SFN, and proves the proposed method through the interference analysis.

The recent growth of the national film and broadcasting industry and the international success of korean films and dramas have resulted in enlarging the financial investment of overall film and drama producing system. Many of local governments contend in the inducement of the drama and movie production because building a drama or movie set help to grow the local business. However, the effort of local governments has rarely achieved the long-term effect. The purpose of this paper is to examine the successful examples of the local specialization as drama or movie set, to compare them with other countries, and to analyze the systematic cause of their success. Moreover, this paper tries to suggest few principles to preplan the successful inducement, to increase the positive outcome, and to invigorate the local area.
