The purpose of this study is to analyze the impact of quality and satisfaction of mobile telecommunication service on the quality data sharing for mobile telecommunication service. Based on the theory of reasoned action(TRA), we proposed a research model that (1) service qualities significantly influence the service satisfaction and the attitude towards information sharing, (2) the attitude towards information sharing mediates between service satisfaction and the intention of information sharing, and (3) the intention of information sharing is affected by the service satisfaction and the attitude towards information sharing. Empirical analysis of mobile service users showed that the data quality of mobile communication services had a greater impact on satisfaction than voice quality. The service satisfaction had a positive effect on attitude towards information sharing and the intention of information sharing. Also, the attitude towards information sharing had a positive impact on the intention of information sharing. Based on this empirical study, we proposed a crowdsourcing as an alternative when quality data of mobile telecommunication service should be collected to improve telecommunication policy because by using collective intelligence of the crowdsourcing the government can gather more accurate and diverse data on mobile telecommunication service.

During extreme ionospheric storms, anomalous ionospheric delays and gradients could cause potential integrity threats to users of GNSS (Global Navigation Satellite System) augmentation systems. GNSS augmentation ground facilities must monitor these ionospheric anomalies defined by a threat model and alarm the users of safely-of-life applications within time-to-alerts. Because the ionospheric anomaly threat model is developed using data collected from GNSS reference stations, the use of poor-quality data can degrade the performance of the threat model. As the total number of stations increases, the number of station with poor GNSS data quality also increases. This paper analyzes the quality of data collected from Korean GPS reference stations using comprehensive GNSS data quality check algorithms. The results show that the range of good and poor qualities varies noticeably for each quality parameter. Especially erroneous ionospheric delay and gradients estimates are produced due to poor quality data. The results obtained in this study should be a basis for determining GPS data quality criteria in the development of ionospheric threat models.

The purpose of this paper is to propose and test a conceptual framework that investigates the effects of perceived service quality on customer satisfaction, attitude toward brand(Ab) and customer loyalty. To test the framework, structural equation modeling are applied to data collected from 210 samples in mobile phone service industry. The results of this research indicated that interaction quality and outcome quality of perceived service quality are positively on customer satisfaction, but the outcome quality is stronger influence than interaction quality. The findings also show that outcome quality effect on directly Ab and then interaction quality effect on indirectly Ab through customer satisfaction. But There are no effect outcome quality, interaction quality and Ab on customer loyalty without customer satisfaction effect. These results include implications that mobile phone service company should have customer satisfaction to retain customer and customer loyalty.

최근 영상의 활용도의 증가에 따라, 비정형 영상 데이터에 대한 양이 기하급수적으로 증가하였다. 디지털 영상을 획득할 시에 처리/압축/저장/전송/재생산 등의 과정을 거치면서 왜곡을 수반하게 되며 영상의 품질을 저하시키는 요인이 된다. 영상의 품질은 활용 결과에도 큰 영향을 미치기 때문에 품질이 저하된 영상은 분류를 하는 것이 중요하다. 하지만 사람이 수신된 모든 영상에 대해서 직접 분류를 하는 것은 많은 시간과 비용이 소요된다는 문제점이 존재한다. 따라서 본 논문에서는 사람이 인지하는 주관적인 영상 품질 평가와 유사하게 품질에 대한 평가를 위한 왜곡영상의 특징정보를 검출 및 분석하는 방안에 대해서 제안한다. 본 방법은 사람이 영상을 인지할 때 가장 많이 사용되는 요소인 색상에 대한 선명도, 블러와 노이즈에 대한 특징정보를 이용한다. 검출된 특징정보를 공간 도메인으로 변환함으로써 왜곡 영상별 특성을 분석하였다. 실험을 위해서 IQA 데이터베이스인 LIVE를 이용하였으며, 원본영상 및 5가지 유형의 왜곡영상으로 구성되어 있다. 실험결과 품질이 좋은 영상과 왜곡영상에 대한 특성을 검출할 수 있었다.
