This study aims to develop a theoretical model in order to determine factors affecting consumer intention to use credit cards by combining Theory of perceived risk and Technology acceptance model. Despite of perspective of consequences in prior studies on related research fields, this study focuses on the sources of perceived risk, including transaction, payment and credit risks, which are proposed and measured in a preliminary research. A measurement model and a structural model with the presence of perceived risk in sources are tested in a formal research with data collected from 538 bank customers. An analysis results show that payment risk, usefulness, transaction risk, ease of use, and credit risk influence significantly Vietnamese consumers' intention to use credit cards in decreasing order of influence. These factors account for 64.6% of the variation in intended use. All three dimensions of perceived risk have a negative effect on the intention to use, with the total impact greater than the level of influence of the other two factors of usefulness and ease of use. These findings can be beneficial to banks in enacting policies to attract more consumers and to allocate resources for improving their credit card business.

Purpose: The purpose of the study was to investigate the effect of loneliness on habitual drug use in Korean adolescents. Methods: The study was designed as a cross-sectional study. Using statistics from the 16th (2020) Korea Youth Risk Behavior Web-based Survey, multiple logistic regression analysis was conducted. A total 54,948 adolescents were included in the analysis. Results: Adolescents were more likely to engage in habitual drug use when they were lonely than when they were not (OR: 1.55, 95% CI: 1.20~2.02). As for sociodemographic characteristics, gender, academic achievement, and living with family were factors influencing habitual drug use. As for health behavior characteristics, perceived stress, depression, current drinking, violence, sexual intercourse, and perceived health were identified as factors affecting habitual drug use. Conclusion: Provision of education that includes loneliness as a factor, which was not previously considered important in school education for preventing habitual drug use of adolescents, should be considered.

The purpose of this study is to investigate the application experience and observation of young children's teachers' digital devices. The participants of this study were 6 young children teachers using digital devices. Individual interviews were conducted as a data collection method. It was conducted 2-3 times per research participant. Data collection was conducted from November to December 2020. The Data analysis was focused on the young children's teachers' digital device application experience and observation use. 'Easy and simple use', 'using existing familiar apps', 'providing healing to teachers', and 'improving the utilization of spare time' were derived as early childhood teachers' experience of applying digital devices. 'Easy use of observation records', 'Use together in various ways', 'Use for parent counseling', 'Use appropriate for observation of revised Nuri Curriculum' through early childhood teacher's experience of observing digital devices ' was derived. As a conclusion of this study, first, it is easy for young children's teachers to apply digital devices to the field. Second, if young children's teachers use digital devices, they can make a wide range of observations, enabling high-quality early childhood education practices.

Background: Whether the use of electronic cigarettes (ECs) is associated with upper airway diseases, including chronic rhinosinusitis (CRS) and allergic rhinitis (AR), remains unclear. Methods: We analyzed data from the nationwide cross-sectional surveys: the Korea National Health and Nutrition Examination Survey VI (2013-2015), VII (2016-2018), and VIII (2019). Logistic regression analysis was performed to assess the association between EC use and CRS or AR. Results: Among a total of 38,413 participants, 6.4% were former EC users and 2.5% were current EC users. Former EC users and current EC showed a significantly increased OR for CRS or AR compared with never EC users. In the subgroup analysis, the "current CC (conventional cigarette)-current EC" and the "current CC-formal EC" group had a significantly higher OR for CRS or AR than the "current CC-never EC" group. In addition, former CC smokers who currently use ECs showed a significantly higher OR for AR than former CC smokers without EC use. Conclusions: EC use is significantly associated with a high prevalence of CRS and AR in the adult population. These results indicate that the use of ECs may increase the risk of upper airway disease.

As the business has been highly informatized, many companies has bought the software for their works. There are two types of software license. One is a site license and the other is a user license. This paper is focused on the user license. User license has the number of the right to use software. So, software managers always need to know the number of licenses in use and should limit the number of software license in use. If someone in the company use a software without license, he will be treated as a piracy. In that case, the company should pay for the settlement cost for the exceeding license use. In this paper, we suggest the model how we can limit the installation of the software within the number of licenses by license management system.

The introduction of the Internet in homes had an effect on family systems. The purpose of this study is to investigate the changes in family systems due to Internet use in South Korea. This study classified the types of changes in the family systems and analyzes the characteristics of each type. Systems approach provides the theoretical framework for this study. First, the cluster analysis demonstrated the three types of the changes in the family subsystems due to housewives' Internet use: 'positive changes', 'negative changes', and 'no changes'. Second, there are different characteristics among the types of changes according to demographic, Internet-related, and intra-system dynamic factors. These results suggest several implications for public policy. To utilize the Internet as a useful tool to improve the quality of family life, housewives must have the ability to control the Internet use and to manage their resources. In order to enhance their abilities of using the Internet, it may be necessary for the government to provide public educational programs for housewives.

This paper describes a method for recognition of two-dimensional position of an object by use of aerial ultra-sonic sensor and signal processing technique, which would become a help for blind person or self-mobile robot. First, we have developed a method for measuring the time difference between the transmitted and the received burst wave by use of one ultrasonic transmitter and three receivers. Secondly, a new method is developed for measuring the distance to an object by use of M-sequence correlation method. Thirdly, a measurement method to obtain the position of an object is described by use of phase-arrayed ultrasonic sensor, which gives us a wide-range position determination in a short time.
