Our study adopted ELM (Elaboration Likelihood Model) to measure the impact of central and peripheral cues on e-healthcare website behavior and its consequence on perceived loyalty of users. While most of ELM studies did not elaborate the antecedent of both central and peripheral cues, we measured the antecedents of those information processing routes to clarify how technical and quality factors (i.e. information organization, security concern, and website attractiveness) develop the nature of either central or peripheral route. We found that information organization was the main antecedent of information quality presented on the website. Second, the results revealed that website security has a positive effect on website credibility. Third, we also found that website attractiveness was positively associated with website credibility. Fourth, consistent with elaboration likelihood model, the empirical findings suggested that information quality (central cue) and website credibility (peripheral cue) were strong predictors of behavior intention to use health website. Our findings also suggested that behavior intention to use health website significantly influenced perceived loyalty.

고객 인게이지먼트는 고객과 브랜드 간의 물리적 그리고 정서적 연결을 의미한다. 고객의 인게이지먼트 정도가 높은 경우 더 많이 구매하고, 더 많이 홍보하며, 더 많은 충성도를 보여준다. 본 연구는 대학 서비스 분야에서 고객들인 학생들이 대학교 내에서 여러 서비스 활동에 대한 인게이지먼트가 학과와 학교에 대한 충성도를 높일 수 있다는 가정에서 출발하여 다음과 같은 시사점을 제시하고 있다. 대학 서비스에서 고객 인게이지먼트는 대학생들이 대학에 만족하고 난 후 대학에 대한 충성도를 강화하는 역할을 한다고 볼 수 있다. 대학만족에 미치는 영향도 있지만 만족 후 더 높은 수준의 마케팅 목표일 수 있는 충성도를 높이는데 큰 역할을 할 수 있다는 것이다. 대학 서비스 인게이지먼트 요소 중 중심적 요소 중에서는 학생들이 미래 취업을 위한 역량 강화 및 진로 관련 활동들을 통해 학과 및 학교 충성도가 높아질 수 있다는 점을 알 수 있었으며 주변적 요소 중에서도 친교활동이 학과나 학교 충성도에 매우 중요한 영향요소로 나타났다. 학생들의 미래 취업을 위한 여러 가지 프로그램과 친교를 맺을 수 있는 여러 가지 프로그램을 통해 충성도를 강화시킬 수 있는 시스템을 구축하는 것이 무엇보다도 중요하다고 할 수 있다. 추가적인 조사에서 학생 집단별 구체적인 인게이지먼트의 조절효과를 검증하지는 못했지만 학생 집단 중 학점이 높은 집단은 중심적 요소 뿐만 아니라 주변적 요소에서도 인게이지먼트 정도가 매우 높은 것으로 나타나 학점이 높은 학생은 주변적 요소에 상대적으로 덜 몰입될 것이라는 상식과는 다르다고 생각된다.

The purpose of this study is to explore the features and features of causes of communicative deficits in high-functioning autistic children in order to intervene educational programs. When communicating with others, high-functioning autistic children have difficulties in the aspects of syntax and semantics, especially pragmatics. These causes of communicative deficits of high-functioning autistic children can be explained respectively by theory of mind, executive function, and central coherence theory. According to theory of mind, qualitative impairment of interaction and communication accounts for communicative deficits. Executive function argues that communicative deficits of high-functioning autistic children be caused by limited concern. Central coherence theory suggests that communicative deficits be caused by the inappropriate integration of cues. Considering these causes of communicative deficits in high-functioning autistic children, we proposed educational strategies order to intervene educational programs.

Apoptotic cell death is a fundamental and highly regulated biological process in which a cell is instructed to actively participate in its own demise. This process of cellular suicide is activated by developmental and environmental cues and normally plays an essential role in eliminating superfluous, damaged, and senescent cells of many tissue types. In recent years, a number of experimental studies have provided evidence of widespread neuronal and glial apoptosis following injury to the central nervous system (CNS). These studies indicate that injury-induced apoptosis can be detected from hours to days following injury and may contribute to neurological dysfunction. Given these findings, understanding the biochemical signaling events controlling apoptosis is a first step towards developing therapeutic agents that target this cell death process. This review will focus on molecular cell death pathways that are responsible for generating the apoptotic phenotype. It will also summarize what is currently known about the apoptotic signals that are activated in the injured CNS, and what potential strategies might be pursued to reduce this cell death process as a means to promote functional recovery.

To make the rationale design of interface between cell and artificial surface, many studies have been controlled influencing cue which can typically be divided into two central categories: chemical cues based on modification surface chemical properties containing attractive/repulsive molecules, and physical cues that may include applied tension/stress, electrical polarization, magnetic field, and topography. Recently, researches have been focused on physical cue, especially topography. The surface topography may influence cellular responses for example, cell adhesion, cell morphology and gene expression. However, there were few systematic studies about these nanotopographical effects on neuronal developments in a feature size-dependent manner. Herein, we report a nanoscale-resolved study of nanotopographical effects on cellular adhesion and growth. In this study, we use substrates with packed glass beads by rubbing method for generating highly periodic nanotopographies with various sizes. We found that acceleration of neuritogenesis appeared only on the beads larger than 200 nm in diameter, and observed that filopodial thickness was comparable with this scale. This study is expected to be essential to elucidate the nanotopographical effect on cellular adhesion and growth.

It is well established that there is a heritable element of susceptibility to chronic human ailments, yet there is compelling evidence that some components of such heritability are transmitted through non-genetic factors. Due to the complexity of reproductive processes, identifying the inheritance patterns of these factors is not easy. But little doubt exists that besides the genomic backbone, a range of epigenetic cues affect our genetic programme. The inter-generational transmission of epigenetic marks is believed to operate via four principal means that dramatically differ in their information content: DNA methylation, histone modifications, microRNAs and nucleosome positioning. These epigenetic signatures influence the cellular machinery through positive and negative feedback mechanisms either alone or interactively. Understanding how these mechanisms work to activate or deactivate parts of our genetic programme not only on a day-to-day basis but also over generations is an important area of reproductive health research.

Under exhibition circumstances, exhibition advertising by organizer is a mean to promote exhibition service to exhibitors and visitors while general advertising is to promote products and services to consumers. The objective of this research is to suggest advertising strategies by seeing differences in the impact of information quality and media credibility on visitor intention depending on the types of exhibition. This study adopted Elaboration Likelihood Model to measure the impact of central and peripheral cues on advertising attitude and its consequence on visitor intention. We further examined how these influence processes were moderated by exhibition types of B2B and B2C. We conducted survey from B2B and B2C exhibitions respectively, and analyzed structural equation model and moderator regression. We found that first, among factors of information quality as a central cue, argument strength has a positive impact on attitude towards advertising. Second, we also found among factors of media credibility as a peripheral cue, media trustworthiness has a positive impact on attitude towards advertising. Lastly, this study revealed that a type of exhibition moderates the central and peripheral routes towards advertising attitude, showing that B2C visitors are influenced by factors of information quality, and B2B visitors rather by media credibility. This study yields implications in that it gives marketers of organizer a background to set different marketing strategies depending on the types of exhibition.

IT education can be summarized as persuading the educatee to accept IT. The persuasion is made by delivering the messages for how-to-use and where-to-use to the educatee, which leads formulation of a belief structure for using IT. Therefore, message based persuasion theory, as well as IT acceptance theories such as technology acceptance model(TAM), would play a very important role for explaining IT education. According to elaboration likelihood model(ELM) that has been considered as one of the most influential persuasion theories, people change attitude or perception by two routes, central route and peripheral route. In central route, people would think critically about issue-related arguments in an informational message. In peripheral route, subjects rely on cues regarding the target behavior with less cognitive efforts. Moreover, such persuasion process is not a one-shot program but continuous repetition with feedbacks, which leads to changing a belief structure for using IT. An educatee would get more knowledge and experiences of using IT as following an education program, and be more dependent on a central route than a peripheral route. Such change would reformulate a belief structure which is different from the intial one. The objectives of this study are the following two: First, an identification of the relationship between ELM and belief structures for using IT. Especially, we analyze the effects of message interpretation through both of central and peripheral routes on perceived usefulness which is an important explaining variable in TAM and perceived use control which have perceived ease of use and perceived controllability as sub-dimensions. Second, a longitudinal analysis of the above effects. In other words, change of the relationship between interpretation of message delivered by IT education and beliefs of IT using is analyzed longitudinally. For achievement of our objectives, we suggest a research model, which is constructed as three-layered. While first layer has a dependent variable, use intention, second one has perceived usefulness and perceived use control that has two sub-concepts, perceived ease of use and perceived controllability. Finally, third one is related with two routes in ELM, source credibility and argument quality which are operationalization of peripheral route and central route respectively. By these variables, we suggest five hypotheses. In addition to relationship among variables, we suggest two additional hypotheses, moderation effects of time in the relationships between perceived usefulness and two routes. That is, source credibility's influence on perceived usefulness is decreased as time flows, and argument quality's influence is increased. For validation of it, our research model is tested empirically. With measurements which have been validated in the other studies, we survey students in an Excel class two times for longitudinal analysis. Data Analysis is done by partial least square(PLS), which is known as an appropriate approach for multi-group comparison analysis with a small sized sample as like this study. In result. all hypotheses are statistically supported. One of theoretical contributions in this study is an analysis of IT education based on ELM and TAM which are considered as important theories in psychology and IS theories respectively. A longitudinal analysis by comparison between two surveys based on PLS is also considered as a methodological contribution. In practice, finding the importance of peripheral route in early stage of IT education should be notable.
