With the proven benefits of and increased interest in using technology in education, the role of teachers has become more important in integrating technology into mathematics classroom. Thus, it is important to improve preservice teachers' technological, pedagogical, and content knowledge (TPACK), which are influenced by their beliefs. This study examines how preservice secondary mathematics teachers' experience and beliefs related to technology use in the mathematics classrooms impact their TPACK. The results of this study show that preservice teachers who have more experience using technology and who hold student-centered beliefs towards technology use display higher levels of technology-related knowledge than preservice teachers who have little experience and who hold teacher-centered beliefs. Understanding the relationships between preservice teachers' TPACK and beliefs provides insights into how teacher education programs can support preservice teachers to develop TPACK and integrate technology into their future mathematics instruction.

While the mobile application market is growing fast, the revenues of the majority apps are declining. Moreover, paid mobile application prices and purchases have been slow because of intensifying competition. However, the conventional studies focused only on the acceptance factor of mobile applications, so they cannot explain the phenomenon such as acceptance resistance for paid mobile applications. Therefore, our study tries to analyze the factors for the acceptance resistance of users for paid mobile applications. The research model in this paper, which is based on S-O-R model, verified through surveys how social influence and app characteristics affect user perception and how user perception affects to app resistance. The results of our study showed that paid mobile applications happened to be destroyed in front of the chasm because of the perceived loss. Consequently, the results implicate that the developers should lower the initial price and actively react to the negative reviews in order to lower the perceived loss. Moreover, the results verified that a sense of self-efficacy can lower application acceptance resistance by including personal properties to our research model as control variables.

This study investigates the antecedents of continuance intention of mobile SNS. In addition, it also explores the mediating role of perceived value in the relationship between the antecedent and continuance intention. This study posits that a social influence, perceived usefulness, privacy concern, and a perceived effort of use are major factors to influence continuance intention of SNS. By using a PLS analysis, this finding suggests that consumers' perception of the value of SNS which is previously overlooked, is a primary determinant of continuance intention, and the other exploratory factors are mediated through perceived value in cognitive aspect. This research aims to examine consumer's SNS continuance intention in terms of consumer's perspective, not just from the technology user perspective. Therefore, this research provides a useful guideline for marketing managers on how to manage Mobile SNS properly.

The people, who can't deal with urine and feces by themselves because they can't recognize it, deal with urine and feces with help of protector (Or nurse). For the case of urine and feces, disease of ulcerated flesh of hip like unpleasant feeling, pressure sore, humid tetter due to wetness of diaper can be prevented by changing diaper instantly. However, those people can't be possible to express their opinion, so they can't express their opinion on urine and feces or endure sense of shame. So there is a problem which can't check presence of urine and feces instantly. Accordingly, in order to solve this problem, qualitative improvement of nursing service can be generated by developing u-Care product which instantly let know urine and feces to protector (Or nurse) by perceiving automatically, and benefit of welfare on social dependent class like low income old people and solitude old people can be increased by reducing social welfare expense with increment of nursing expense.

With the advent of the autonomous driving era, automobiles are being discussed as an extension of the media. The growth of the in-vehicle infotainment(IVI) system can provide various benefits and values to the driver and passengers. Although the development and research of related technologies is being carried out, there has been no research that specifically identified users' valuation on the main attributes of IVI systems. This study uses conjoint analysis to investigate key attributes and users' preferences. The results indicate that the most important attribute for IVI system is provider, followed by system operation type, main service and content type. For each attribute, consumers prefer a detachable infotainment system provided by a telecommunication company, and prefer to use information-oriented services and content that they have previously consumed. This paper provides practical implications, especially in terms of convergence, that operators can refer to in IVI development.

The purpose of this study was to examine the cognition-perception factors and oral health promotion behavior of dental hygiene and non-dental hygiene students in an effort to find out factors affecting their oral health promotion behavior. After a survey was conducted, the collected data were analyzed. The findings of the study were as follows: 1. In regard to cognition-perception factors of oral health, the dental hygiene students were ahead of the others in self-efficacy, control of oral health and benefits of oral health behavior. The latter felt there were more barriers to their oral health behavior than the former. 2. As to the practice of oral health promotion behavior, that behavior was more prevailing among the dental hygiene students than the others. Both groups restrained themselves from liquor and cigarettes. 3. Concerning the correlation between oral health promotion behavior and related variables, self-efficacy and control of oral health had a significant correlation to oral health promotion behavior. Better self-efficacy and better control of oral health led to better oral health promotion behavior and better practice of its subfactors 1, 2 and 3. 4. As a result of checking the variables affecting oral health promotion behavior and the subfactors of the variables, self-efficacy had the largest impact on factor 1, factor 2, factor 3 and oral health promotion behavior, and factor 2 was under the greatest influence of control of oral health. Based on above-mentioned findings, self-efficacy was identified as the cognition-perception factor that had the largest impact on oral health behavior. Therefore how to boost self-efficacy should be considered when oral health promotion programs are developed, and research efforts should be channeled into finding out in which way self-efficacy could be bolstered in association with each kind of oral health promotion behavior.

In order to reinforce the role of primary care physician and o improve doctor-patient relationship, the Korean government tried to introduce 'Family Doctor Registration Program' into Seocho-Gu in Seoul, Ansung-Gun and Paju city in Kyunggi-Do in Oct. 1996. Community residents and doctors in those area did not show much interest in this project because of low incentives. We have done this study to see how much people know 'Family Doctor Registration Program' and what is people's real needs about 'Family Doctor Registration Program'. We selected 1,800 telephone numbers in Seoul, Chongju city, and Ansung-Gun by multi-stage stratified random sampling. Three trained survey personnels called them and got answers to the premade questionnaire until they completed the questionnaires of 200 persons in each community. The calling time was 7-9 p.m. from Monday to Friday, 3-9 p.m. on Saturday, and 9 a.m. to 9 p.m. on Sunday. We dropped out the persons who did not respond 3 times. The subjects consisted of 222 male and 367 female residents. Their ages ranged from 20 to 78: 24.8% in their 30s, 23.4% in their 20s, 22.5% in their 40s in male, and 35.2% in theirs, 22.5% in their 40s, 18.5% in their 20s in female. 9.9% of male and 13.2 % of female had their Family Doctors. The specialties of their Family Doctors were internists in 56.2%, general surgeons in 11.0%. The persons who did not have their family doctors were asked which doctors they would prefer if they had choices of family doctor. The results were internists in 50.3%, family physicians in 13.0%, pediatricians in 4.8%. Only 16.0% residents knew that government tried to introduce Family Doctor Registration Program. The 'Family Doctor Registration Program' was not well known to people. The results of our study showed that more effective incentives and public notifications are needed to activate this program.

Recently, as competition in the market evolves from the competition among companies to the competition among their supply chains, companies are struggling to enhance their supply chain management (hereinafter SCM). In particular, as blockchain technology with various technical advantages is combined with SCM, a lot of domestic manufacturing and distribution companies are considering the adoption of blockchain-oriented SCM (BOSCM) services today. Thus, it is an important academic topic to examine the factors affecting the use of blockchain-oriented SCM. However, most prior studies on blockchain and SCMs have designed their research models based on Technology Acceptance Model (TAM) or the Unified Theory of Acceptance and Use of Technology (UTAUT), which are suitable for explaining individual's acceptance of information technology rather than companies'. Under this background, this study presents a novel model of blockchain-oriented SCM acceptance model based on the Technology-Organization-Environment (TOE) framework to consider companies as the unit of analysis. In addition, Value-based Adoption Model (VAM) is applied to the research model in order to consider the benefits and the sacrifices caused by a new information system comprehensively. To validate the proposed research model, a survey of 126 companies were collected. Among them, by applying PLS-SEM (Partial Least Squares Structural Equation Modeling) with data of 122 companies, the research model was verified. As a result, 'business innovation', 'tracking and tracing', 'security enhancement' and 'cost' from technology viewpoint are found to significantly affect 'perceived value', which in turn affects 'intention to use blockchain-oriented SCM'. Also, 'organization readiness' is found to affect 'intention to use' with statistical significance. However, it is found that 'complexity' and 'regulation environment' have little impact on 'perceived value' and 'intention to use', respectively. It is expected that the findings of this study contribute to preparing practical and policy alternatives for facilitating blockchain-oriented SCM adoption in Korean firms.

Mobile wallet that can keep coupons and membership cards for mobile is one of rapidly growing services due to its usability and financial benefit. However, in spite of its rapid growth, the increase of users who do not use continuously it is an important consideration to service providers for making a profit. This study aims to test the effects of factors affecting the continuous use intention of mobile wallet based on VAM (Value-based Adoption Model) which can analyse them in both benefit and sacrifice aspects, so as to suggest considerations to increase the use period of mobile wallet for service providers. The research findings supported the hypotheses regarding to the effects of usefulness, value-expression, perceived security and enjoyment in the benefit aspect and technicality in the sacrifice aspect on perceived value. In addition, the causal path from perceived value to continuous use intention was significant. The study results are expected to be used in marketing or service improvement for short-term users by taking account of emotional factors as well as functional factors.

Sustainable development brings many potential advantages to the society and environment. As such, many educational communities have concentrated on incorporating this concept into their educational programs for the K-12 classrooms. The K-12 technology educators have also exerted efforts to infuse the sustainable development concept into the K-12 national-curriculum level. The purpose of this study was to investigate the high school students' attitudes towards sustainable development. The study participants were 1,073 high school students from six high schools in Gyeonggi province. A self-reported instrument was used to obtain the students' demographic information and to come up with an attitudinal scale towards sustainable development. This study employed statistical ways of exploring the attitudinal level of the South Korean high school students and of describing the subcategories of the sustainable development. The findings described the high school students' attitudes towards sustainable development with regard to three components: (1) cognition of sustainable development; (2) practices in pursuit of sustainable development; and (3) perception of the education for sustainable development. The exploratory factor analysis supported three perspectives of the students' attitudes towards sustainable development. Also, the qualitative data collected and analyzed from the students' responses to the open-ended question posed to them indicated two domains of the students' cognition of and practices in pursuit of sustainable development. These findings were made on the bases of several recommendations regarding the research on and implementation of Education for Sustainable Development(ESD).
