Despite the growing amount of mobile peer-to-peer (P2P) payment applications available on mobile app stores, these applications are still in their infancy and have yet to see mass adoption. This study aims to explore the factors that influence the adoption of such mobile P2P payment applications by using a large-scale data set based on the tracking of users' actual mobile application usage behavior. Our main findings reveal that the duration of each session that users use of traditional bank application has a significant relationship with their adoption of mobile P2P payment applications. In addition, we explore the social aspect of such mobile P2P payment applications by analyzing their social network applications usage and found that the amount of social network service applications used and usage duration positively impacted one's adoption of mobile P2P payment applications. These findings have important theoretical and practical implications for stakeholders of mobile P2P payment solution providers as well as intermediaries/banks who provide their own payment applications to their customers.

In modem days when architectural materials have grave impacts on overall design expression, materials for architecture, especially finishing materials have become the most essential elements for the design expression, as architectural space and form have been. This study closely verifies the concept of tensity analyzed in preceding studies by quantifying it through experimentation and questionnaire, and suggests possible alternatives which verified concept of tensity applies into the architectural design. It was examined how architects consider the finishing materials through a questionnaire. With a questionnaire, the possibility of quantificative analysis for tensity is evaluated by SPSS program. Moreover, a questionnaire about the social image that the architectural finishing materials have was also conducted. This questionnaire results In the actual methods to apply quantificated psychological tensity and social images into the architectural design and recommends better plan to select finishing materials for each spacial function and usage, Due to the great influence of social images in design expression, the application mechanism of the tensity should follow the general and individual principles together. With the tensity figure and application of social images we can find more resonable method for material selection.

For many social scientists, the comparative method has been a part of the common enterprise of describing, explaining, and developing theories about socio-cultural phenomena. However, it is rare that comparison has been methodologically considered in architectural history in spite of the usefulness for understanding the similarities and differences among architectural styles. This research emphasizes the importance of comparative methodology in architectural history and proposes an example which can be introduced from the comparative method for social studies. The application in this study is based on the assumption that an architectural phenomenon is a kind of social phenomenon and comparative method in social study can be applied to architectural history. The method is to generate and test hypotheses through establishing functional correlation between variables treated as the objective facts that differentiate one type of building from another.

The development of information technology and the demands of society on an application in an operating system, as well as increasing the specifications and sophistication of smartphones, require banks to make changes to their mobile banking applications. The transformation of the mobile banking application into a digital banking application conducted by banks has made users re-evaluate based on their preferences. This study presents the behavior of users of digital banking applications in Yogyakarta, Indonesia. The hypothesis model is based on Technology Acceptance Model (TAM) with additional factors of the social image, perceived risk and perceived trust adopted from Muñoz-Leiva et al. (2017). The methodology in this study includes data collection through questionnaires distributed online and data analysis using the Structural Equation Model. The results of this study illustrate that the perceived trust and perceived risk have a more dominant part in influencing user attitude and user intention to use digital banking. Meanwhile, social image, perceived ease-of-use and perceived usefulness are not significant in influencing user attitude and user intention to use digital banking. The implication of this research helps to determine the right communication and strategy so that more users with more benefits can utilize this digital banking application.

빅데이터 시대를 맞아 다양한 도메인에서 수없이 많은 데이터들이 생산되면서 데이터 사이언스가 대중화 되었고, 데이터의 힘이 곧 경쟁력인 시대가 되었다. 특히 전 세계 데이터의 80% 이상을 차지하는 비정형 데이터에 대한 관심이 부각되고 있다. 소셜 미디어의 발전과 더불어 비정형 데이터의 대부분은 텍스트 데이터의 형태로 발생하고 있으며, 마케팅, 금융, 유통 등 다양한 분야에서 중요한 역할을 하고 있다. 하지만 이러한 소셜 미디어를 활용한 텍스트 마이닝은 수치형 데이터를 활용한 데이터 마이닝 분야에 비해 접근이 어렵고 복잡해 기대에 비해 그 활용도가 높지 못한 실정이다. 이에 본 연구는 프로그래밍 언어나 고사양 하드웨어나 솔루션에 의존하지 않고, 쉽고 간편한 소셜 미디어 텍스트 마이닝을 위한 통합 애플리케이션으로 Korean Natural Language Application(KoALA)을 개발하고자 한다. KoALA는 소셜 미디어 텍스트 마이닝에 특화된 애플리케이션으로, 한글, 영문을 가리지 않고 분석 가능한 통합 애플리케이션이다. 데이터 수집에서 전처리, 분석, 그리고 시각화에 이르는 전 과정을 처리해준다. 본 논문에서는 디자인 사이언스(design science) 방법론을 활용해 KoALA 애플리케이션을 디자인, 구현, 적용하는 과정에 대해서 다룬다. 마지막으로 블록체인 비즈니스 관련 사례를 들어 KoALA의 실제 활용방안에 대해서 다룬다. 본 논문을 통해 소셜 미디어 텍스트 마이닝의 대중화와 다양한 도메인에서 텍스트 마이닝의 실무적, 학술적 활용을 기대해 본다.

This study aims to provide an in-depth description of the practices of social media users in the Kingdom of Saudi Arabia (KSA)-specifically the users of Facebook and Snapchat-and the reasons for these practices, the decisions made, and the people involved. Qualitative methods were used to collect data in two rounds from 53 participants. The data analysis shows a clear preference for Snapchat over Facebook among the participants, as shown in their using the application many times daily and in the creation and use of new words derived from the application's name. On the other hand, one of the main reasons mentioned by the participants for not preferring Facebook was the unclear policy of security and privacy used in the application. This reason is important for all social media users, but, in particular, it is crucial for female users, as shown in the data. This is important for the designers and policymakers of the social media applications to understand and consider, as it would help them improve the current applications and create new ones.

The purpose of this study is to investigate and analyze the service satisfaction of users using community service, and to suggest directions for continuous growth and high service of social service providers in the future. This study was conducted on G metropolitan cities. T-test and one-way ANOVA were conducted for the comparison of 476 users of social service users by gender, income level, and age. In addition, multiple regression analysis was conducted to identify factors affecting user satisfaction. The statistical package analyzed was SPSS 21.0. As a result of the study, the application process, the satisfaction of the service period, and the satisfaction of the service provider were statistically significant at the income level. In addition, in the age group satisfaction, the application procedure, the satisfaction of the service period, the satisfaction of the service frequency, and the satisfaction of the workforce were statistically significant.

Everyday, technology is evolved in many different disciplines. Computer and smart devices revolution take part of the evolved technology that continuously promising new features. Moreover, social networks services recently become widely popular, which most people in the world become a social-network-fond. In addition to the revolution of the evolved technology and social networks services, ubiquitousness is taking significant part in our daily lives. Although, there are many e-learning systems already existed, which use Internet technology along with a Web technology to provide education in various ways, in despite of that, there is no such existing system exploits the usefulness of smart devices along with the legacy of the online social networks besides the power of the ubiquitous computing technology. Therefore, we propose a smart device application, which fills the gap that has been missing in the recent contemporary era. It is an application that runs on smart devices particularly Smartphone devices; we call our system “Smart Device based Social E-learning System(SDES)”. We have preliminary implemented our system on Android OS. In this paper, we intentionally propose the system in order to ease the way people learn, to provide interactive accessibility in our system, and to utilize the advanced technology more wisely.
