Internet-based financial services are being increasingly integrated into consumers' daily lives. Internet-only banks have emerged as a powerful tool accelerating financial inclusion. This study investigates the satisfaction and continuous use intention predictors for Internet-only banks. We employed an extended post-acceptance model and used six antecedent factors that included perceived usefulness, perceived ease of use, privacy risk, functional risk, subjective norms, and network externality. All 351 participants used Internet-only banks and were 20-40 years of age. A self-administration online survey was conducted. SPSS 23.0 analyzed the frequency, description, and multiple regression analysis. The results of current study are as follows. The education, perceived usefulness, perceived ease of use, and network externality positively influenced the satisfaction of Internet-only banks. Privacy risk negatively influenced satisfaction with Internet-only banks. Perceived ease of use, subjective norm, network externality, and satisfaction positively influenced the continuous use intention of Internet-only banks. The results of our study provide a better explanation of important factors that could enhance the understanding of satisfaction and continuous use intention for Internet-only banks. Furthermore, this study extends the antecedent variables to the knowledge of financial services and enlarges the understanding of users' post-adoption behaviors.

The goal of this study is to investigate the relationship between maternal rearing behavior characteristics and elementary school children's Internet use, and to utilize the results as the basic data to develop a program, in which parents learn how to educate their children for better use of the Internet. The subjects were 713 children whose grade are in fourth through sixth in an elementary school. Data were obtained with questionnaires. The instruments employed were Children's Internet Use and Addiction, and maternal rearing behavior characteristics-Rational Guidance, Affection, Authoritarian Control, Overprotection, Achievement Encouragement, and Active Involvement-Scales. The data were analyzed with the SPSS program. They were analyzed by Frequency, Percentage, ANOVA, Duncan's test, and Pearson correlation. The results of this study are as follows: First, 30.2% of the subjects has used Internet for more than three years. 55.6% of the subjects spend less than an hour per day in using the Internet. The two major types of Internet use were playing games(49.9%) and sending e-mails(25.4%). The main reason for playing Internet games was escape from stress(34.7%). 34.5% of the subjects also said that their parents usually encourage them to use the Internet. Second, maternal affection, authoritarian control, and active involvement were significantly different in the types of Internet use. Maternal authoritarian control and overprotection were significantly different in the reasons of doing Internet game. The rational guidance and active involvement of mothers were correlated negatively with children's Internet using time, but their authoritarian control and overprotection were correlated positively with children's Internet using time. Maternal overprotection was correlated positively with parents' encouragement level in the Internet use. Third, the rational guidance, affection, and active involvement of mothers were correlated negatively with children's Internet addiction. In the other hand, maternal authoritarian control and overprotection were correlated positively with children's Internet addiction. Lastly, children's Internet addiction was significantly different by the types of Internet Use and the reasons for doing internet game.

Recently, new devices have been developed for the Internet of Things concept. The devices commonly use RF (Radio Frequency) based wireless communication. With the increase in the number of devices, the space allocated for the radio frequency band in wireless communication fills rapidly. Visible Light Communication (VLC) is an alternative, secure and economical communication technology that uses light instead of radio frequencies. While Web of Things (WoT) is the adaptation of the experience and knowledge acquired from the web into the internet of things ecosystems. By combining these two technologies, the development of the Visible Light Communication for Web of Things (VLC4WoT) system, which can use VLC and WoT technologies, has been our motivation. In our study, microcontroller control circuit was created for VLC4WoT system. Control of the circuits over the internet was performed. VLC based receiver and transmitter units have been developed for wireless communication. Web based interface was created for control. The test apparatus consisting of four objects with four outputs and a transfer unit was carried out. In this test, communication was achieved successfully. It was presented in the study that VLC can be used in the web of things architecture. In the future, it is envisaged to use this system as a safe and economical system in indoor environments.

Objectives: The purpose of this study was to evaluate the association between Internet use and oral health behaviors in Korean adolescents. Methods: This study used the 13th Korea Youth Risk Behavior Web-based Survey (2017) to find an association between Internet use and oral health behaviors. The total number of study subjects was 54,603. A chi-square test and multiple logistic regression analyses were used to estimate the association between Internet use and oral health behaviors. Results: Internet use was significantly increased among female, higher school grade, lower school records, and lower economic status participants (p<0.001). The rate of frequency of toothbrushing more than three times daily and use of oral hygiene devices was increased among female, higher school record, and higher economic status participants significantly (p<0.001). Oral symptoms experienced were significantly increased among female, higher school grade, lower school records, and lower economic status participants (p<0.001). The rate of the toothbrushing more than three times daily and toothbrushing after lunch groups was the highest in the group with less than one hour of Internet use, but the rate of oral symptoms experienced was the highest in the group with over five hours of Internet use. The risk of toothbrushing less than twice daily was 1.61 times higher in the group with over five hours of Internet use, and the risk of not brushing after lunch was significantly higher (1.52 times) in the over five hours group. The risk of not using oral hygiene devices was the highest (1.22 times) in the less than five hours group, and the risk of oral symptoms experiences was 1.40 times higher in the more than five hours group. Conclusions: Internet use was related to oral health behaviors in adolescents. Appropriate Internet use and awareness of oral health care are needed among adolescents.

This study aims to analyze the frequency of the use of internet web sites for information on landscape trees, and to suggest an improved direction for internet information content concerning of landscape trees. 10 areas of 5internet web-sites that are presented by an internet search with Yahoo Korea, Empas and Naver were studied for their importance and satisfaction degrees by landscape architects who use them. The users recognized the importance of the contents of the internet web-sites for landscape trees, but were not satisfied with it. It was proposed that the web-sites should provide higher quality information on the growth history, price, shipping and handling, payment and the place of origin. Especially, the paper proposes that web-sites should more aggressively utilize information on the quality of landscape trees such as tree forms, trimming states of roots, etc.

This study aims to investigate gender differences in the use of ICT by the students of urban schools. The objectives of the study are to find out the use of computers and Internet by the students and also the problems encountered by them while using computers and Internet. The study found that there is a significant association between the place (p=.005) and frequency (p=.002) of use of computers and gender. It is also found that there are significant differences in the problems faced by students while using computers (p=.002), use of Internet (p=.004), and the gender. This clearly indicates that there exists a gender disparity in the use of ICT by the male and female students in the urban schools. In order to overcome this disparity, the school authority should provide the basic and necessary ICT infrastructure in schools which can be equally used by male and female students.
