  • Purpose - This study was aimed to investigate the moderating effects of cobranding promotions that are rare in brand experience and brand loyalty studies, and to find out cobranding promotions can play a moderating role to enhance positive effects on the relationship between brand experience and brand loyalty, and to figure out the cobranding types which can lead to positive brand loyalty. Research design, data, and methodology - The conceptual research model was developed to explain the effects, and 2018 Interbrand's global top 15 brands such as Apple, Google, Amazon, Samsung were suggested to be selected from 377 Amazon Mechanical Turk respondents to answer the 22 survey questions made by Qualtrics with 5-point Likert scale. Results - In this research, the moderating effects of cobranding have been confirmed on the relationships between brand experience and loyalty, and the positive cobranding promotions can have significant effects on the relationships, but only for the least experienced brand was significant. Regarding to cobranding types, there were no significant ones to enhance brand loyalty. Conclusions - The findings confirmed that cobranding promotion experience can play a positive moderating role to brand loyalty, and the loyalty can be maximized if companies can provide positive cobranding experiences to their own consumers.

  • Purpose: The purpose of this article is to identify whether the physical therapists perceive the important factors influencing the motor development in children with cerebral palsy differently. Methods: Study participants included 58 pediatric physical therapists. They were recruited from the internet communities for physical therapists. The data was collected through a web-based questionnaire using Google Documents tool. Questionnaire was focused on the importance (10-point scale) of each factor influencing the motor development in children with cerebral palsy. The mean scale of each factor was compared by itself and according to the participants' career characteristics. Results: The personality characteristics received the least importance rating (6.77) in comparison with other domains (healthcare service: 7.70, family ecology: 7.53, secondary impairment: 7.53, primary impairment: 7.45). In the detailed items, home exercise (8.33) received the highest mean importance rating, while sociability (6.03) received the lowest mean importance rating. Comparing the importance of factors by the type of work institution, subjects working in the welfare institutions perceived the contextual factors (personality characteristics, family ecology, healthcare service) as more important than those working in the medical institutions. Conclusion: The authorsuggests that pediatric physical therapists should try to have an identical approach by reaching a consensus. Also, the support for family-centered service to children with cerebral palsy should be strengthened.

  • The main aim of study is to identify the factors that affect the purchasing intention of young adults. The reference group is an important factor in determining the underlying causes of young adults' purchasing intentions. However, the literature states that young adults prefer to buy brands they trust in order to eliminate the risks that may arise when buying products they may not know. Moving from this perspective, the study proposes a conceptual model that including structural relationships between brand trust, reference group, and purchasing intention. The study aims to contribute to the literature by discussing the moderator role of brand trust in this structure. A series of hypotheses are tested via a survey completed by 749 young people between the ages of 20 and 30 living in Istanbul, Turkey. The data were analyzed with IBM SPSS-23 and AMOS-18 program. In addition to descriptive, reliability, and factor (exploratory and confirmatory) analysis, hierarchical regression analysis was performed to test the research hypotheses. The results show that the reference group positively influences the purchasing intention, and brand trust plays a moderating role in this relationship. The findings are discussed and some practical suggestions are made for mobile phone manufacturers.

  • This study aims to improve knowledge of consumers' decision-making by testing a conceptual model that considers the hotel's service quality and service value toward customers' behavioral intentions using a mediator, which is the role of consumers' satisfaction. The object of this research is five-star hotels, which has become a significant segment of the general hotel industry and is undergoing rapid expansion. This research is a quantitative research using questionnaire as the sampling method answered by people who have stayed at five-star hotels before. The total of 150 valid respondents were used in this study. The collected data was processed by a statistical tool software, Partial Least Square (PLS). The major findings of this research showed that the relations between service quality and service value of five-star hotels do not have significant positive impact on consumers' behavioral intention, nonetheless the mediation analysis shows that customers' satisfaction partially mediates service quality and service value with consumers' behavioral intentions to stay. It means that in this case, consumers' satisfaction has an important role to mediate service value quality and service value. As a result, the study shows that four out of six hypotheses are supported. A couple of recommendations are suggested for further research.

  • This study investigates the factors affecting Industry 4.0 adoption in the curriculum of university students in Ho Chi Minh City, Vietnam. Universities need to respond to the changing faces of Industry 4.0 and, hence, Education 4.0. A mixed method including both qualitative and quantitative methodologies was utilized. An in-depth interview was carried out for exploring, reviewing, and testing content validity of constructs and measurement items. The pilot study was conducted with 120 respondents. The conceptual model and hypotheses were developed using data collected by a questionnaire survey distributed to 584 respondents by both electronic and paper forms with non-probability and convenience sampling techniques. The result of structural equation modeling showed that occupation relevance, skills, facility conditions, and social influence impacted on the intermediates variables, namely, relevance advantage, perceived usefulness, behavioral intention-to-use, and actual use. The independent variables are occupation relevance, skills, facility conditions, and social influence. They impact actual use through mediating constructs such as relevance advantage, perceived usefulness, and behavioral intention-to-use. The findings suggest that universities and students' efforts aimed at increasing the factors' perceptions of adoption of Industry 4.0 will contribute to implementation success, where success is defined as effectual usage of Industry 4.0.

  • This study was conducted to provide information about weight control behavior in adolescent females. To explain the behavior intention of dieting, conceptual framework based on "Social Support, Control and the Stress Process Model" and "Theory of Reasoned Action" was used. The survey was carried out by self-questionnaires with 463 female high school and college students in Daegu. Analysis of data was done using mean, correlation and multiple regression analysis with the SAS computer program. A society preoccupied with thinness gives a burden to women, and this burden may stress dissatisfaction with body image. Social perception of ideal body image except parents' perception, and salient others'perception, and salient others' expectation of subjects' body image except parents' expectation, were much thinner than normal figures in this study. The influencing factors for behavior intention of dieting of the subjects were perceived stress and attitude toward diet behavior, especially beliefs of behavioral outcome. Influencing factors related to perceived stress-that is dissatisfaction of body image-were current figure, social perception of body image, effect of mass communication and others' estimation of subjects' body image with self-comparison with others, in order.th others, in order.

  • Quality control of science teachers seems to be one of the most important tasks to improve the quality of science education in Korea. The purposes of this study, as a survey, were to identify characteristics of good science teachers and to make an outline of preservice teacher education curriculum for cultivating the characteristics from inserivce secondary science teachers. A questionnaire was developed for this study and distributed to 176 inservice teachers. It had three parts: 1) characteristics of good science teachers, 2) weights of preservice curriclum areas, and 3) weights of college courses. The means and standard deviations of teachers' responses were calculated. To test the differences between teacher variables, t-tests were executed. The inservice teachers perceived that the junior-high school teacher's characteristics should be different from the senior-high school teacher's. Characteristics, such as enthusiasm toward teaching or students, subject knowledge, content selection and organizing skill, teaching techniques, and scientific worldview were ranked within top five of good science teacher's chracteristics. The teachers' perception about preservice curriculum were as follows: 1) present weight of liberal arts area should be reduced: 2) weight of content area for junior-high school teachers should be different from that for senior-high school teachers: 3) present weight of pedagogy area should be increased: 4) present weight of science education area should be increased: and 5) many courses in pedagogy and sciencd education areas need to be changed, Based on the data and disussion, a conceptual model for preservice teacher education curriculum was proposed.

  • Seismic resiliency of new buildings has improved over the years due to better seismic codes and design practices. However, there is still large number of vulnerable and seismically deficient buildings. It is not economically feasible to retrofit and upgrade all vulnerable buildings, thus there is a need for rapid screening tool. Many factors contribute to the damageability of buildings; this makes seismic evaluation a complex multi-criteria decision making problem. Many of these factors are noncommensurable and involve subjectivity in evaluation that highlights the use of fuzzy-based method. In this paper, a risk-based framework earlier proposed by Tesfamariam and Saatcioglu (2008a) is extended using Fuzzy-TOPSIS method and applied to develop an evaluation and ranking scheme for steel buildings. The ranking is based on damageability that can help decision makers interpret the results and take appropriate decision actions. Finally, the application of conceptual model is demonstrated through a case study of 1994 Northridge earthquake data on seismic damage of steel buildings.
