Purpose The purpose of this study is to investigate the nature of temporal non-use, namely, the type of temporal non-use and the dynamic relationships between temporary non-use and use by expanding the model of dynamic state transition of non-use which is proposed by the previous study. Design/methodology/approach This study adopted grounded theory methodology as a research methodology. Fifteen university students were interviewed for open coding and for selected coding which leads the research model ten students were interviewed. Findings Based on the coding, the types of use were divided into interactive use and one-way use, and the types of temporal use were classified into temporal non-use in which use is intended and temporal non-use in which use is not intended. The dynamic transition model is presented for each type of use and temporalnon-use, and an integrated model that combines them is presented. This study found the following four things: First, all non-use can be temporal Second, there are different types of temporal non-use. Third, the pattern of use is not just one, but new patterns will continue to emerge. Fourth, we found a change in the function of SNS.

Perceived control and use of Information and Communication Technology (ICT) has long been known as important aspects of students' achievement. The purpose of this study was to explore the relationship between adolescents' perceived achievement goals, their Individual ICT use, ICT use for government-sponsored educational programs on television or the Internet, academic achievement and the attitude toward learning. Most previous research has employed cross-sectional data analysis using relatively small samples. For this purpose, this study used the datasets of the Seoul Education Longitudinal Study (SELS 2011) from Seoul Educational Research & Information Institute. We analyzed structural equation modeling (SEM) a nationally represented sample (4,346 eighth-grade students). The results of this study showed that students' perceived achievement goals had a positive relationship with their individual ICT use, and their use of ICT programs for government-sponsored educational programs on television or the Internet. Also, students' individual ICT use had a positive relationship with their achievement, but ICT use for government-sponsored educational programs on television or the Internet did not have a significant relationship with their achievement. That is, students' individual ICT use mediated the relationship between their perceived goals and academic achievement. In addition, results indicated that students' individual ICT use and ICT use for government-sponsored educational programs on television or the Internet had a positive relationship with their attitude toward learning. That is, both students' individual ICT use and ICT use for government-sponsored educational programs on television or the Internet mediated the relationship between their perceived goals and their attitude toward learning.

Objective: The aim of this study was to introduce newly developed cooperation group standards of acupuncture needles for single use and to make a contribution to the future development of Korean Industrial Standards (KS) of acupuncture needles for single use. Results and Conclusion: Quality assurance and quality control with high safety profile is one of the most critical issues in medical device manufacturing. Up to now, proper attention has not been paid to this issue with respect to acupuncture needles for single use and their related devices. We, therefore, organized a committee to make guidelines to produce an acupuncture needle with high quality and safety. In the committee, we reviewed the topic from an historical viewpoint, and investigated the current situation of the standardization of acupuncture needles in other developed countries. Finally, we developed the cooperation group standards in advance of development of KS on the acupuncture needles for single use. The standards are composed of 12 sections describing: Scope, Normative references, Definitions, Materials, Configuration, Appearance and Cleanliness, Quality, Sterilization and Safety, Processing of Surface and Coating Material, Test, Packaging, and Labeling. We hope that the standards would be useful guidelines to produce high quality acupuncture needles and play an important role in the development of KS in the future.

The purposes of this study were 1) to investigate parental amounts of Internet use for purpose of rearing 2) to investigate their environment and preparation level to use Internet as educational information source 3) to investigate whether there are differences between Korean and U.S. parents in environment, level of preparation, and amounts of use of Internet for purposes of child rearing 4) to find out the factors of use of Internet for purposes of child rearing. The questionnaire used in this survey included five sections : background, environment, preparation, amount of total Internet use, and amount of Internet use for purposes of child rearing. Participants were 282 parents (128 American; 154 Korean) with at least one 3~ to 7-year-old child. Findings revealed that parents used the Internet frequently, but they did not frequently use the Internet for purposes of child rearing. There were differences between Korean and U.S. parents in environment, level of preparation, and amount of Internet use for purposes of child rearing. The main factor that affected use of the Internet for purposes of child rearing was 'trustworthiness of Internet information'. Finally, it was suggested the implications for better Internet use for purpose of rearing from the findings.

Purpose: To promote condom use for young men, there is necessary to meet their varying needs for condom. The purpose of this study was to examine what predicts condom use intention according to experience of sexual intercourse among Korean male college students. The conceptual framework for the study was the theory of planned behavior and the health belief model. Methods: A cross-sectional descriptive design was used with self-report questionnaires, which were completed by 399 subjects. Logistic regression analysis was done to examine predictors of condom use intentions according to experience of sexual intercourse. Results: The susceptibility to sexual transmitted diseases/ Acquired Immune Deficiency Syndrome (STDs/AIDS) and pregnancy and benefits from condom use were significant predictors of condom use intentions in the non-experienced group. The significant predictors of condom use intention for the experienced group were barriers to condom use and condom use self-efficacy. Conclusion: These findings suggest that sex education program should be developed to overcome barriers to condom use, enhance condom use self-efficacy, and maximize the benefits from condom use as well as increase the perceived susceptibility to STDs/AIDS and pregnancy. To enhance condom use self- efficacy, practicing and increasing ability in interactive negotiation to use condom should be included.

In the age of continuous media change and the coexistence of multiple forms of media, the relationship between the public's media use and political participation is an urgent area of study. This paper makes use of large national sample surveys from 2002, 2011, and 2015, summarizes the change of the public's media use by descriptive statistics analysis, and finds that while the Internet has become an important communication channel, the use of Internet for political information and political participation is still overestimated. Compared to the weak impact of different media channels for political information on political participation, the frequency of media exposure and Internet use play a significant role in political participation. Because of the negative effect of the frequency of Internet use on political participation, the democratization function of the Internet needs to be treated with caution. This paper describes media use and its roles in contemporary China, analyzes the impact of media use on political participation, and extends the cross-cultural application of the theory of political communication.

This study verified the motivation to use Tiktok for Chinese teenagers. This paper investigated the influence of adolescents'use motivation on use satisfaction and continuous use intention. In addition, this study was to grasp the relationship between use motivation and sustained use intention as a mediating effect of use satisfaction. The survey was conducted online and offline, 315 adolescents were selected for analysis. For the data, factor analysis, multiple regression analysis, and effect analysis of parameters were conducted using the SPSS 25 program. As a result of the study, information/entertainment pursuit, communication, and self-expression were derived as motivation for use. Among these motivations, information/enterprise pursuit and communication were found to have a significant effect on use satisfaction and continued use intention. In addition, it was confirmed that use satisfaction has a mediating effect on intention to use continuously. But it is found that the self-expression factor handled as reuse intention have no significant influence on the use satisfaction and continuous use intention of Tiktok.

Land-use in northern Cheongju region is changing rapidly because of the increased interactions of human activities with the environment as population increases. Land-use change detection is considered essential for monitoring the growth of an urban complex. The analysis was undertaken mainly on the basis of the multi-temporal Landsat images (1991, 1992 and 2000) and DEM data in a post-classification analysis with GIS to map land-use distribution and to analyse factors influencing the land-use changes for Cheongju city. The area of each land-use category was also calculated for monitoring land-use changes. Land-use statistics revealed that substantial land-use changes have taken place and that the built-up areas have expanded by about $17.57km^2$ (11.47%) over the study period (1991 - 2000). This study illustrated an increasing trend of urban and barren lands areas with a decreasing trend of agricultural and forest areas. Land-use changes from one category to others have been clearly represented by the NDVI composite images, which were found suitable for delineating the development of urban areas and land use changes in northern Cheongju region. Rapid economic developments together with the increasing population were noted to be the major factors influencing rapid land use changes. Urban expansion has replaced urban and barren lands.
