Deep learning in computer vision has made accelerated improvement over a short period but large-scale learning data and computing power are still essential that required time-consuming trial and error tasks are involved to derive an optimal network model. In this study, we propose a similar image classification performance improvement method based on CR (Confusion Rate) that considers only the characteristics of the data itself regardless of network optimization or data reinforcement. The proposed method is a technique that improves the performance of the deep learning model by calculating the CRs for images in a dataset with similar characteristics and reflecting it in the weight of the Loss Function. Also, the CR-based recognition method is advantageous for image identification with high similarity because it enables image recognition in consideration of similarity between classes. As a result of applying the proposed method to the Resnet18 model, it showed a performance improvement of 0.22% in HanDB and 3.38% in Animal-10N. The proposed method is expected to be the basis for artificial intelligence research using noisy labeled data accompanying large-scale learning data.

This study was conducted to verify the factors affecting self-esteem of the 50-69 aged with low income in single person households. The subjects were 233 single households in the 50-69 aged low income from the 2019 welfare panel data provided by the Ministry of Health and Welfare. The dependent variable was defined as self-esteem, and independent variables were relationship satisfaction and life satisfaction. Data analysis was carried out by using SEM analysis, As a result, relationship satisfaction did not have a direct effect on self-esteem, with a low value (path coefficient =0.24). However, relationship satisfaction positively influenced life satisfaction (path coefficient =0.71), and life satisfaction positively influenced the self-esteem (path coefficient =0.46). Thus life satisfaction between relationship satisfaction and self-esteem had a mediator effect on self-esteem with 0.32 value. Therefore, establishing the strategy which supports poor single person households, policy makers should consider methods improving relationship satisfaction and life satisfaction.

In the case of SAE autonomous driving levels 2 and 3, since complete autonomous driving is impossible, the take-over process is essential, and take-over time(TOT) is the most important factor in determining the safety of the autonomous driving system. Accordingly, research on TOT is being actively conducted, but each research is independently conducted and general conclusions that integrate various research results are required. Therefore, in this study, the factors affecting TOT were analyzed using meta-analysis, which integrates the results of individual studies and presents an integrated opinion. As a result of meta-analysis, a total of 10 influencing factors were selected, and most of them were related to the non-driving related task(NDRT) type. In addition, implications for the future research direction of take-over and NDRT were presented.

대한민국은 2017년 이후 저출산·고령화사회로 진입하였고 생산가능인구가 감소함에 따라 노동생산성이 낮아지고 있으며, 여성의 경력단절 문제가 심각한 사회문제로 대두되고 있다. 정부에서는 여성가족부와 고용노동부가 함께 여성의 경력단절 예방과 해결을 위해 다양한 지원창업과 경제활동을 장려하고 있지만 현실에서의 재취업장벽과 열악한 노동환경, 일과 가정의 양립 문제 등으로 인해 경력단절 여성들 특히, 고스펙·고학력의 여성들은 취업이 아닌 창업을 선택하고 있으나 창업의 성공률은 그다지 높지 않아 다양한 대비책이 요구되는 실정이다. 여성 기업가는 창업부터 성장하기까지 수많은 위험요소에 노출되어 있으며 이러한 위험요소를 체계적으로 관리하고 극복하는 노하우를 쌓아 잘 활용하였을 때 경제활동의 핵심주축으로 성장할 수 있으며 창업이라는 혁신적이고 생산적인 활동으로 전환해 일자리 창출 및 기업의 혁신과 나아가서는 국가경제발전에 기여할 수 있는 토대가 될 수 있다. 본 연구의 목적은 여성의 기업가정신이 창업성과에 미치는 영향을 실증 분석하는데 있다. 경력단절여성 창업자를 대상으로 기업가정신이 창업성과에 미치는 영향과 회복탄력성이 조절효과를 갖는지 여부를 확인하고자 하였다. 여성기업가 특유의 소비자의 욕구를 세심하고 활동적으로 파악하여 생활밀착형 아이디어가 풍성면모와 창조적인 아이디어를 갖고 적극적으로 실행해보고자 하는 진취적인 성향과 회복탄력성이 창업성과에 영향을 미칠 것이라는 상황에 초점을 두고 연구모형을 설정하였다. 이를 위해, 기업가정신의 구성요소를 '혁신성', '진취성', '위험감수성'을 독립변수로 구성하였고, 창업성과의 주요구성요소인 '재무성과', '비재무성과'를 종속변수로 설정하였다. 또한 회복탄력성을 조절변수로하는 연구모형을 상정하였고 이는 여성의 기업가정신과 창업성과의 관계에서 회복탄력성의 조절효과여부를 확인하여 여성의 기업가정신교육과 회복탄력성의 중요성을 밝히고 활성화를 목적으로 하고 있다. 본 연구는 여성의 기업가정신이 창업성과에 긍정적 영향을 미친다는 것을 규명했다는 점에서 시사점을 갖는다. 심각한 사회문제로 떠오르고 있는 여성의 경력단절 문제를 해소하기 위해 향후 중소벤처기업부 및 여성가족부, 고용노동부 등에서는 여성창업자를 대상으로 체계적인 기업가정신교육과 회복탄력성에 관한 교육을 시행할 것을 제언한다.
