The level of competition has reached the limits in cellular phone market and the cellular phone manufacture companies started to focus their solution in user interface. Design issues with controllability led the development and renovation of such products to the use of the touch-screen phone. Depending upon the readability, technical advances, portability and controllability, user satisfaction of touch-screen phones could vary significantly. In this research, the controllability was dealt in regard to various grip postures, in order to improve menu layout which fits for using the thumbs of both hands and a thumbs of single hand. Regression models are found to the suggest the location of buttons on the screen by redesigning the menu layout, it is expected to improve both controllability and satisfaction of the user. This result can be applicable not only to mobile phone design, but also to the design of various hand-held devices using a touch screen.

A web based E-mail system consists of serves which supply mail accounts and service, and clients which take part of interfacing with users. The web browsers such as Netscape Navigator and Internet Explorer are the popular clients. Users who cannot afford to get an E-mail id in general mail servers are, therefore, able to reach a e-mailing service in the web environment by using client programs in connection with a mail server. Although the quality of service has been upgraded a lot in recent days, it doesn't provide with satisfactory services anymore. In this paper, we intend to design a mail agent system based on the web environment. Through this system we could reach a convenient user interface based on Internet Explorer and could easily access administratory environment on the basis of NT Server 4.0. Using the service engine dominent in mail agent system, it could provide with convenient user interfacing tools like responding the absence of users, mail filtering and refusing messages, etc. And it would ultimately make possible a constant system security, by preventing system failure phenomena caused by extraordinary uses beyond its capability.

Purpose: In the past, the South Korean government made various efforts to attract Chinese tourists, resulting in gradually more inbound tourists. In 2016, the number of Chinese tourists to South Korea peaked at 8.06 million and became the top source market. Nevertheless, increasing numbers of consumers choose to adopt the mobile payment tool instead of cash and credit cards in modern times with developed IT services. Research design, data, and methodology: IBM SPSS AMOS 23.0 and IBM Statistics 23.0 were used to analyze the data, which was collected from hotel employees in China from March 25 to May 10. Results: First, Interactivity, security, convenience, local information supply and user interface had positive effects on satisfaction and reliability. Second, it was believed that the convenience of Alipay played a positive role in increasing reliability and satisfaction through verification. Third, the role of use rate was found to be important in the development of Alipay functions. Conclusions: Based on the result, an analysis on the development of the Alipay market and the use of Alipay in South Korea is warranted. Furthermore, this paper will serve as a basis for flexible strategic plans for the development of Alipay and SMEs in South Korea.

This paper examines new phenomenon and transformation that arise from the expansion of knowledge-based economy, envisions the meaning of e-government through comparing traditional administration with new governance, formulates the e-government model, and presents a direction for next e-government for the conclusion. These new phenomenon include a transformation to product and service convergence model, cyber sovereignty dilemma, privacy and information security threats, and various others. Also, there is a gradual transformation from government-oriented administrative approach to a new governance model that strengthens the role of NGO. And, e-government must work together to realize this new governance ideology. New e-government must be transformed where government and citizens can implement and manage e-government together. Therefore, expanding applications of Public Key Infrastructure (PKI) technologies, promotion of e-Democracy, and improvement of user interface to improve usability must be emphasized.

Banking industries have continuously innovated through technology-enhanced products and services. Many studies have recognized the importance of the Internet in banking industries, arguing that it has been widely adopted. Many studies published on the Internet banking in specific countries are mostly related with such issues as internet banking adoption and acceptance, security and risks of online banking system, and interface design. Several studies have been done to examine the differences and similarities between other banking channels and the Internet banking. However, to the best of our knowledge, only a limited number of studies has examined the differences and similarities between two specific countries in order to create a new customer satisfaction model. In this research, we studied the internet banking satisfaction model by comparing two countries: South Korea and Indonesia. We conducted an empirical study based on the data collected in both two countries. In this research, we found that countries which have adopted electric banking services, particularly between a country with high ICT adoption and a country with low ICT adoption, show different satisfaction trends. Based on the study results, herein we provide discussion, managerial, and practical implications.

Data are a critical utility asset. Collecting correct data on site leads to accurate information. Data, when gathered with foresight & properly formatted, are useful to both existing database and easily transferable to newer, more comprehensive historical outage data. However, when investigating data items options, the task, can be an arduous one, often requiring the efforts of entire committees. This paper firstly discusses the KEPCO's past 10 years of historical outage data which include meterological data, and also by several elements of the National Weather Service, failure rate, outage duration, and probability classification, etc. Then, these collected data are automatically stored in an Outage Data Management System (ODMS), which allows for easy access and display. ODMS has a straight-forward and easy-to-use interface. It lets you to navigate through modules very easily and allows insertion, deletion or editing of data. In particular, this will further provide the KEPCO that not only helps with probabilistic security assessment but also provides a platform for future development of Probability Estimation Program (PEP).
