This paper aims to develop a framework that can fully automate the quality management of training data used in large-scale Artificial Intelligence (AI) models built by the Ministry of Science and ICT (MSIT) in the 'AI Hub Data Dam' project, which has invested more than 1 trillion won since 2017. Autonomous driving technology using AI has achieved excellent performance through many studies, but it requires a large amount of high-quality data to train the model. Moreover, it is still difficult for humans to directly inspect the processed data and prove it is valid, and a model trained with erroneous data can cause fatal problems in real life. This paper presents a dataset reconstruction framework that removes abnormal data from the constructed dataset and introduces strategies to improve the performance of AI models by reconstructing them into a reliable dataset to increase the efficiency of model training. The framework's validity was verified through an experiment on the autonomous driving dataset published through the AI Hub of the National Information Society Agency (NIA). As a result, it was confirmed that it could be rebuilt as a reliable dataset from which abnormal data has been removed.

This study defines the silver portal as a specialized internet portal that will be probably popular with the pre-senior/senior internet users who are over 40, sooner or later. The purpose of the study is to analyze what types of online contents on the silver portal are mostly preferred by the pre-senior/senior, and does the preference of those content types vary according to the demographic and the internet usage characteristics of the pre-senior. The study also is to suggest some research propositions, based on the analysis results, that could be applied to empirical studies in the future which deal with various research questions on the silver portal. To accomplish these research purposes, the study performed a survey for the prospective silver portal users who are living in the areas of Seoul and Kyeonggi, South Korea, and did various statistical analyses. This study found that the preference of content types of the silver portal vary according to some personal characteristics of the prospective silver portal users, and moreover proposed a few of research propositions on the relationships between personal characteristics and preferred content types.

특허권을 지적재산권이라고 한다. 부동산처럼 타인에게 양도할 수 있으며, 두 사람 이상이 공유할 수도 있고, 빌려줄 수도 있다. 쉽게 말해서 특허권을 가지고 있으면 돈이 되는 것이다. 그렇기 때문에 특허권에 대한 관심이 증폭되고 있다.
