There is an increasing need to use mobile Internet as a research tool as wireless technology has been developing rapidly. However, little research has been conducted to confirm methodological validity of mobile Internet survey. This study examines the possibility of using mobile Internet as a survey tool by comparing survey results of mobile and stationary Internet surveys with the same questionnaire. The results were analyzed from both economic and theoretical perspectives. Both mobile and stationary Internet survey sites were implemented with supports from domestic mobile and stationary Internet portals and telecommunication companies. The results show that there exist several differences between two survey methods. First, many respondents who use mobile Internet gave up at the early stage. However, once people continued to respond, they answered the questions to the end. Second, means and standard deviations of mobile internet respondents were higher than that of stationary Internet. Third, the results of two survey methods were significantly different by comparing construct validity that includes both discriminant validity and convergent validity. Finally, this paper ends with implications and limitations of using mobile Internet as a survey tool.

모바일 조사방법은 유선전화조사와는 달리 응답대상자에 대한 접촉가능성이 높기 때문에 새로운 조사방법으로 활용되기 시작하였다. 그러나 모바일 조사방법의 표본 대표성을 확보할 수 있는 방법론이 아직 정립되지 않았다. 이 연구는 성향지수를 이용한 가중치를 사용하는 것이 모바일 조사의 표본편향을 제거해 줄 수 있는지 검토해 보았다. 성, 연령, 학력 등의 인구학적 속성과 기타 태도변인을 이용하여 성향지수를 산출하여 가중치로 사용하였다. 그 결과 선거예측조사와 과학 여론조사 등에서 표본의 편향이 감소되는 것으로 나타났다. 그러나 이러한 본 연구의 결과가 일반성을 어느 정도 가지는가는 좀더 검토되어야 할 것이다.

The rise and fall of social research methods rely on how much a certain method is able to appropriately reflect the change of society. The present research proposes new mobile surveying methods, considering the current and future trends in Korea. In particular, this research focuses on environmental pressure (time constraints, the presence of others and the place) as one of the major factors influencing the effects of survey modes. For example, landline surveys are conducted in the respondent's home, which is a private and fixed space. On the other hand, surveys on mobile phones can be conducted in diverse places with other people around. After sampling 500 landline respondents and 500 mobile phone respondents using a quota method, the same questionnaire was used for both the mobile and landline interviews. The findings are generally consistent with the literature supporting the data quality and comparability of the mixed mode survey. These results are encouraging for researchers designing surveys that feature mobile phone data collection.

The aim of this study lies in answering the question "How to form weighting cells to enhance sample representativeness in telephone, Internet and mobile surveys\ulcorner". For this, we explored 2% raw data of Year 2000 Population and Housing Census of Korea looking for meaningful patterns for ownership of telephones, the usage of Internet and/or mobile phones. We found that telephone coverage rates vary significantly by household size; 84.6% for one member households, contrasting 98.5% for two-or-more member households. Thus, telephone survey samples need to be weighted differently in sub-groups by household size for proportional representation of target population. Searching socio-demographic factors influencing the use of Internet by C5.0 tree models, we found that education levels and the occupation (or housing type, the automobile ownership) are two most important factors in addition to gender and age. Thus, surveyor might form weighting cells by such factors at the stage of post-stratification or set quotas, a priori, proportional to size of the cells by such factors. For mobile surveys, we approached similarly and found that education levels and the occupation (or the automobile ownership, marriage status) are two additional factors that may be used in forming weighing cells or in setting quotas for cells.

The purpose of this study was to investigate the changes in the use of mobile phones due to COVID-19. The subjects of this study were those who lived in Jeju City and used their own mobile phone for more than 2 years, and were included in adult men and women aged 15 to 80 years old. The purpose of this study was explained and a questionnaire survey was conducted on 156 people who agreed. The survey period lasted from June 15 to July 4, 2020. As a result, the daily use time and function of the mobile phone, which were used more than before the occurrence of COVID-19, increased. This was a statistically significant trend (p<0.001) with increasing trend after COVID-19 in all age groups. In addition, in the mobile phone function, all age groups used more 'KakaoTalk' than 'call', but it was found that only the group with less than 1 hour of daily using time used the call function a lot.

Mobile voting has been considered as a promising technology, but it has not been used widely or popular enough in the world. We think this situation is caused by immature technologies of mobile voting and no agreement among people in our society. In this paper, we reviewed literature on electronic voting systems in order to find out technical issues on mobile voting system, and we also surveyed people's opinions via the Internet in order to understand what they worry about mobile voting. From the literature review, we understand that the existing electronic voting systems did not consider security, robustness, and reliability issues enough. From the survey, we also get to know that people worry about "manipulation of the result of mobile voting" mostly. Our work can help researchers on mobile voting to consider the ways or technologies that convince people of the reliability of mobile voting.

The rapid pace of adoption of mobile handsets has created new mobile financial services. The success of mobile financial information systems will depend on consumer self-efficacy and a sound business model. Self-efficacy has been described as the belief that one is capable of performing in a certain manner to attain certain goals. This is directly related to consumer behavior, but it also affects consumer behaviors indirectly through its impact on goals. And self-efficacy influences the challenges that people take on as well as how high they set their goals. The objective of the study to investigates the effect of self-efficacy on mobile financial information systems. In order to do that, self-efficacy, mobile financial information systems reliability, mobile financial information systems use intensity are conceptualized by survey questionnaire. Our empirical analysis based on 462 survey data shows that self-efficacy effects on mobile financial information systems quality. In addition we also found that self-efficacy effects on mobile financial systems reliability and usage intention. And we found that mobile financial information systems reliability effects on mobile financial systems use intention. And we also found that mobile financial information systems usage intention effects mobile financial systems quality.

This study attempted to demonstrate the role of perceived value and trust in the relationship between mobile banking service quality and use satisfaction. A survey was conducted on customers of Mongolian banks, and an analysis was conducted based on the collected data With the development of the fintech industry, the Internet-based mobile banking market is striving to provide convenient services to consumers. The result led to the introduction of an online-oriented Internet bank that can operate 24 hours a day regardless of time and space. The characteristic of operating only with the Internet has a positive aspect of providing services quickly and conveniently, but at the same time, including concerns about security and personal information leakage. This can make you hesitate to use the service. Therefore, we attempted to find out how the quality of mobile banking service affects the perceived value and satisfaction of using trust. A survey was conducted to verify the contents of the research model and hypothesis. This is to secure data to be used for empirical analysis of research hypotheses. The survey was conducted with 124 consumers in Ulaanbaatar, the capital of Mongolia. Based on the analysis results, we understood the satisfaction of consumers using mobile banking and suggested ways for consumers to improve their actual satisfaction using mobile banking. Specifically, service quality sensitivity, security, convenience, and design had a positive effect on perceived value or trust, ultimately leading to consumer satisfaction.
