The purpose of this study was to explore whether PPAT drawing using an application can be developed on digital devices for game addicts. The PPAT drawing test is useful and reliable for verifying problem-solving skills in how people pick apples. As a result of this study, the over-immersion group scored lower than the average user group in the "problem Solving" category of the PPAT drawing test using the PPAT drawing applicaion on digital devices, and expressed by not reaching for apples, or by picking apples without reasonable support. The findings in this study suggest that the PPAT drawing test application on digital devices has significantly demonstrated its original purpose of 'problem resolution', as well as future psychotherapeutic interventions for Internet over-immersion subjects as well as users who are familiar with digital devices.

각종 디지털기기가 빠르게 보급되고 정보와 통신, 방송기기 및 컴퓨터 등이 하나로 연결되는 컨버전스 현상이 급속히 진행되면서 영화 속에서나 일어날 법한 일이 속속 현실화되고 있다. 이에 따라 10년 동안의 비즈니스 목표를 찾지 못하던 기업들도 저마다 새로운 승부수를 띄우고 있다. 특히 고부가가치 산업인 디지털콘텐츠는 글로벌기업들이 눈독들이는 분야다. 이미 애니메이션시장이 대표적인 제조업인 조선시장보다 훨씬 크고, 게임시장도 반도체 시장을 앞지르고 있다. 인프라 변화추이를 알아봤던 지난호에 이어 차세대 환경에서 각광받는 디지털콘텐츠 분야를 살펴봤다.

The purpose of this study was to investigate the relationship between the self-efficacy and intention to use for digital health devices by middle-aged and aged groups. We conducted the frequency analysis, T-test analysis, and linear regression analysis using the 2019 Korean Senior Technology Acceptance Survey. The analysis results are as follows. First, the group of the middle-aged had higher score of the intention to use for digital health devices than the group of the elderly. Second, the group of the middle-aged group also had higher self-efficacy than the group of the elderly. Lastly, it was found that the relationship between the self-efficacy and intention to use was not significant in the middle-aged group. However, the relationship between the self-efficacy and intention to use in the elderly group had a positive influence. We suggested that the differentiated strategy is needed to promote the utilization of digital health devices for middle-aged and aged. This study is expected to be a fundamental study of digital health devices and suggest the research model including the usefulness, ease of use, and anxiety.

2006년도 국내 광산업의 시장규모는 약 17조원으로 전년대비 약 15.7% 증가한 것으로 예측된다. 이것은 세계시장의 약 5.5%를 차지하고 있으며 2010년에는 세계시장의 10% 정도에 이를 것으로 추정된다. 2006년도 국내 광산업의 생산규모는 27조원으로 시장규모보다 많으며 전년대비 약 16.9% 증가한 것으로 예측된다. 즉 내수보다는 수출위주로 그 비중을 계속 확대할 것이다. 여기서 광정밀기기, 광정보기기, 광학기기가 약 80%를 차지한다. 특히 향후 수출전망과 관련하여 디지털 카메라와 폰 카메라 등은 중국등 후발 국가들의 추격이 예상되지만 국가적으로 중요한 수출품목으로써의 역할을 계속할 것으로 기대되며, 그중에서도 중국에서의 시장확대가 계속될 것으로 전망된다.

We conducted the analysis using the data of the '2019 Korean Middle and Elderly Technology Acceptance Survey' to verify the comprehensive senior technology acceptance model. In this study, we examined the significant effect the relationship between behavioral intention to use the diital health devices and perceived usefulness, perceived ease of use, gerontechnology self-efficacy, gerontechnology anxiety, facilitating conditions, attitude to life and satisfaction through the structural equation. The results of the research model are as follows. First, the usefulness and ease of use had significant effects on intention to use. Second, the self-efficacy had significant effects on the intention to use. But they had negative effect. Third, perceived usefulness, self-efficacy and anxiety had significant effects on ease of use. Lastly, self-efficacy, facilitating conditions, attitude to life and satisfaction had significant effects on perceived usefulness. These findings highlight that verified the comprehensive senior technology acceptance model in Korea.
