As Mobile Internet users grow rapidly, Mobile Internet Companies will be in a fierce race to catch a new customer. In this situation, companies want to identify of what factors make peoples use Mobile Internet in order to develop the effective Mobile Internet services and to supply the higher service quality. However, prior researches on Mobile Internet focused on technical area such as higher data delivery, efficient compression of images, so they do not have given companies beneficial materials for making fascinating Mobile Internet service. To offer the service development materials, this research investigated important factors to use Mobile Internet from the viewpoint of customer. Moreover, the study was progressed how much these factors influenced Mobile Internet actual usage. After being surveyed service adopting model and significant factors in Marketing and in MIS(Management Information System), this study was suggested Mobile Internet Adopting Model reflected in Mobile Internet characteristics. To collect the effective data, Internet survey had been done for two weeks. The respondents were identified if they were real Mobile Internet users and how much they had used Mobile Internet for a month. The results were that important factors of Mobile Internet usage were Usefulness, Usability, System Quality and Instant Connectivity. Perceived Value of Mobile Internet influenced Mobile Internet Behavioral Intention significantly and Behavioral Intention had a significant effect on Mobile Intent usage by results. This paper concludes with discussion of these results and their implications for researcher and Mobile Internet company managers.

These days mobile phone which were used mainly by grown-up persons are now widely used among children as well due to new social demands. Despite this trend, existing mobile phones are still being designed and produced according to the taste of people in their 20s and 30s, even the elderly, not satisfying physical, emotional and cognitive characteristics raised by children. This study aimed to extract the design factors of mobile phones for children by reflecting functional factors requested by children and parents in QFD's customer demands. First, functional and design factors requested in mobile phones for children were extracted from existing products and documentary records and some functional factors were selected through a process of integration and omission. The survey research was conducted on children and parents, based on the selected functional factors. Based on the survey research, functional factors were analyzed using AHP, and key functional factors considered by children and parents in mobile phones for children were investigated. Finally, in order to reflect the results in QFD, the correlation between functional factors and design factors was constructed as HOQ through experts' evaluation. The results showed that both children and parents recognized the basic functions such as telephoning, text messaging and phone directory as high priority functional factors, even though the relative importance was different between children and parents. Therefore, it is likely to satisfy the desires of both children and parents by designing mobile phones for children in consideration of design factors such as menu depth, button independence and button arrangement. It is expected that this study will promote experiments on design factors and propose basic data for and guidelines to mobile phone design for children.

Mobile Banking Applications (MBAPs) is one of the recent fads in mobile trading applications (Apps). MBAPs permit users to execute exchanges of money and many more whenever it might suit them; however, the primary issue for mobile banking Apps is usability. Hardly any investigation analyzes usability issues dependent on user's age, gender, exchanging accomplices, or experience. The purpose of this study is to determine the degree of usability issues, and experience of mobile banking users. The survey employs a quantitative method and performs user experiment on 240 participants with six different tasks on the application's interface. The post experiment survey is done with concerning participants. On the other hand, banking experts and Information Technology (IT) expert's group is also involved after the experiment. Expert's opinions about existing mobile banking Apps and suggestions for improving usability of MBAPs are collected through physical means (like questionnaire and interview) and online means like Google form. After that comparison of the opinions of users and experts about MBAPs is performed. The experimentation measures the tasks usability of various mobile banking apps with respect to its effectiveness, efficiency, trustfulness, learnability, memorability and satisfaction. The usability testing was led at different Universities and the outcomes acquired show that there are privacy and trust issues with their mobile banking apps. There is also a gap between users and experts which should be minimized by applying customized usability models, modes concept like other application software and also by adding complete features of banking in MBAPs. It will benefit mobile banking apps users, developers and usability engineers by providing user-friendly which are up to the mark of user's requirements.

This study uses S-O-R framework to examine the relationships among consumers' perception of economic benefits, usefulness, privacy risks, switching cost, and emotions and continued intention usage. Results from an online survey of 324 qualified respondents were analyzed using the structural equation model. The results of the survey showed that first, perceived economic benefits and perceived usefulness has a positively effect on consumers' positive emotions. Second, perceived privacy risks have a negative effect on consumers' positive emotions. Third, perceived usefulness has a negative effect on consumers' negative emotions. Fourth, perceived switching cost has a positive effect on consumers' negative emotions. Fifth, consumers' positive and negative emotions have an effect on continuous usage intention. Sixth, consumers' positive and negative emotions have a mediating effect. The S-O-R model can explain consumer's continued intention to use mobile payment services. The study analyzed the emotional elements of mobile payment services. Emotional elements through mobile payment services can be applied to other financial services. Therefore, this study can guide emotional related practices with various future consumer electronic services.

Purpose - This study explores the relationships between e-Marketing and perceived service quality with brand trust and loyalty towards the brand of mobile telephone operators in Kosovo. Research design, data, and methodology - The conceptual model of four constructs was developed, while each construct consisted of the set of variables measured by using five-point Likert scale. The primary data was collected via an online survey through SurveyMonkey, distributed via Facebook and email. The collected data were cleaned, validated and tested for its consistency through Cronbach's Alpha; ensured that five assumptions of multiple linear regression are met. To assess the relationships between outcome variable and dependent variables of the model, performed the bivariate correlation, simple, multiple linear and hierarchical regression. Results - Perceived service quality has a positive significant effect on brand trust and loyalty. e-Marketing presents moderating direct effect on brand loyalty, and slightly higher effect through brand trust of the mobile telephone operators in Kosovo. Conclusions - The perceived service quality and brand trust are key determinants in achieving brand loyalty in telecommunication industry, followed by e-Marketing as means to creating expectations, delivering on promise to meet customers' perceptions for service quality with a purpose of building trust, that leads to loyalty towards the brands of mobile operators in Kosovo.

CCD 카메라, GPS 및 IMU 등을 갖춘 모바일매핑시스템은 도로를 따라서 도로 영상 뿐 만 아니라 동시에 주변 시설물에 대한 많은 정보를 취득할 수 있다. 그러나 취득된 다수의 파일은 후처리 작업이 많을 경우 자료의 누락 또는 변질이 발생할 가능성이 매우 높다. 또한 다양한 조사지역에 대해서 여러 조사팀에 의해 자료가 생산되기 때문에 자료들이 상충하거나 품질이 차이가 날 수 있다. 본 연구에서는 보다 체계적인 모바일 매핑 자료 관리를 위해 영상 태그 규격인 Exif를 이용하여 정밀한 GPS 시간과 필수 정보를 내재화하여 조사자료 관리 체계를 위한 일관된 관리식별코드로 활용한다. 또한 대용량 영상파일과 관련 정보를 합리적이고 체계적으로 관리될 수 있도록 자료 동기화 기술을 이용한다.
