A polymer porous sheet, which can be applied to diverse wearable devices, has some advantages such as light-weight, high flexibility, high elongation, and so many others. In order to fabricate a porous sheet, water-soluble particles like sugar were utilized frequently, and there has been great advances. However, with our best knowledge, there are not enough reports on the mechanical behavior of porous sheets having different porosity. So, in this work, we tried to find out the relationship between porosity and mechanical deformation of a porous sheet. The process parameters such as a particle size, sheet thickness and PDMS mixing ratio with curing agent were analyzed on the effect of increasing the porosity of a sheet. Also, mechanical deformation of a sheet was tested using a tensile experiment. Through the experimental results, we make a conclusion that a highly porous sheet with thin thickness has high flexibility, and it deformed nearly double elongation comparing to worst one among nine cases.

The rapid increase in smartphone ownership underscores the importance of service delivery in the mobile environment. Accordingly, the public sector is allocating budget and effort towards providing services through mobile applications. While some have recorded high download numbers, contributing to the proliferation of public services, issues such as low user engagement and budgetary concerns have simultaneously been raised. This study aims to analyze factors influencing the intention to use public apps with the theoretical foundation of the Technology Readiness Acceptance Model (TRAM) to enhance users' acceptance of public apps. Previous research has primarily focused on system characteristics, but this study constructs the model with a significant consideration for user characteristics. Additionally, through a comprehensive examination of publicness, which has been lacking in existing research, the study integrates this aspect into the model. Ultimately, this research provides insights into the factors influencing users' intention to use public apps and suggests approaches to enhance usage intention for the successful implementation of a Digital Platform Government.

This study attempted to analyze factors influencing S-DMB adoption. The theoretical background of this study is 'Technology acceptance model.' Based on this theory and literature review this study set 5 hypotheses. For this research, a survey was conducted by online research lab. from October 25 to 31. Data were collected from 350 subjects. Complete and useable questionnaires were received from 303 respondents. The result and conclusion are as follow: 'Instant accessibility,' 'service quality,' 'Cost,' 'advertising,' 'perceived easy of use' are significant factors influencing 'perceived usefulness'. 'Compatibility,' is a significant variable influencing 'perceived easy of use'. However, 'self efficacy' and 'innovativeness' are not significant factors influencing 'perceived easy of use.' The result of the analysis showed that most of the hypotheses were verified the same as preceding studies, but some results were different with the result of preceding studies. Therefore, it implies the characteristics of S-DMB different with other IT systems and mass media that were research subject mostly before, and it influences the result of this study as well.

Many studies have been conducted on adoption of healthcare applications. However, few studies have paid their attention to continuous usage intention of healthcare applications even though success of healthcare applications is determined by Continuous usage intention rather than adoption. Therefore, this study tried to identify the factors affecting the continuous usage intention of healthcare applications and examined the relationship between them empirically. In addition, the role of gender and age in the relationship was investigated. The results showed that self-efficacy and innovation had a significant effect on perceived ease of use of healthcare application, while self-efficacy, health information seeking, and enjoyment had a significant effect on perceived usefulness. Perceived ease of use and usefulness showed positive impact on continuous usage intention of healthcare application. Finally, age and gender had a moderator effect the relationship between perceived usefulness and continuous usage intention. This study is expected to make contributions to the existing research by identifying the factors affecting the Continuous usage intention of healthcare applications, but also to give a guideline for managers who want to provide healthcare application services.

This research was conducted to find out about the effects of a perceived usefulness and a perceived ease of use on the viewer's attitude and their intention to use of the Terrestrial UHD Broadcasting. The survey was conducted with 191 respondents while innovativeness, relative advantage, active engagement, accessibility and affinity were considered as the external variables for this research. As the result shows, the external variables that affect the perceived usefulness are affinity, relative advantage, and innovativeness. However, it was confirmed that the accessibility has no major effect on the perceived usefulness. Among the external variables, the innovativeness has the highest level of effectiveness on the perceived usefulness of UHD broadcasting. Relative advantage, active engagement, and affinity were followed in orderly fashion. Especially, the perceived ease of use on UHD broadcasting has a major effect on the perceived usefulness. Also, the perceived usefulness affects the viewers' attitude and their intention to use. And the research verified that there is no correlation between the perceived ease of use vs. attitude and between attitude vs. intention to use. Therefore, we can safely say that the perceived usefulness of UHD broadcasting has main effects on viewers' attitude and their intention to use of UHD broadcasting.

Due to the nature of teenage students' common tendency of being drawn to consumption conformity engendered by popular trends, and further expanding their unique collectivist culture, this study presumes that middle and high school female students as well have an influential factor that creates their distinctive trait. This study is intended to investigate the students' personal characteristics and effects of social reference groups, and further scrutinize how these influences transcends to deviant make-up behaviors. A total of 297 subjects, middle and high school female students, participated in a survey, using questionnaires focused primarily on the degrees of color makeup and the influences imposed by classmates. The findings of the study are as follows. First, regarding makeup behavior displayed by middle and high school female students, social self-esteem had positive influence on innovation and peer pressure. Second, perceived visibility conversely had negative impacts on innovation and peer pressure. This indicates that if perceived visibility is at a salient level, this already signifies lack of innovation. Third, makeup innovation and peer pressure demonstrated by middle and high school students all showed positive influence on their makeup behaviors. Additionally, peer pressure, in comparison to innovation, had greater influence on makeup behaviors, which indicates that peer pressure play a great role in makeup behavior of middle and high school students. Fourth, makeup behaviors showed strong impacts on makeup satisfaction and rendering deviant behaviors, which indicates that a new direction and perspective regarding middle and high school students' makeup behavior is critical.
