Due to the explosive growth of smartphone use, new type and format of business opportunity is being created. Despite the creation of added value using smartphone is very important, the past study on smart phone has been mainly focused on its functions and specifications. This study is intended to identify the factors that influence continuance usage intention of smartphone and to analyze the relationship between such factors and the expected confirmation. satisfaction, and usage intention. The result of this empirical study indicates that the perceived enjoyfulness and quality significantly affect users' expected confirmation and satisfaction, and social influence also affects users' continuance usage intention. Thus, it implies users place a high value on enjoyfulness and quality in using smartphone application and on social influence in choosing specific application. Finally this paper provides a detailed account of how customers accept smartphone application and their perceived characteristics affect the usage intention.

The paper examines the antecedents of acceptance of social networking sites in retail franchise and restaurant businesses. The success of retail franchise and restaurant business operators via social networking sites depends not only on organizational benefits but also on their behavioral intentions of using it. Three hundred and twenty four samples collected from South Korean retail franchise and restaurant employees are analyzed using factor analysis, structural equation model techniques and one-way analysis of variance. The results of the study identify the three constructs of organizational benefits, perceived tangible assets and perceived intangible assets as for important antecedents to accept social networking sites for their business use. Moreover, higher position employees tend to have more favorable perception of tangible assets and acceptance of social networking sites for their business use.

The purpose of this study was to examine how Korean students accept and use mobile-assisted language learning (MALL) and investigate related factors that potentially affect MALL usage. The participants were 244 undergraduate students who were surveyed with a questionnaire. The research model, which included students' self-efficacy, content reliability, interactivity, perceived enjoyment, perceived usefulness, perceived ease of use, attitude, and behavioral intention to use MALL, was developed based on the technology acceptance model (TAM). The structural equation modeling (SEM) technique was employed in order to analyze the overall results of modified TAM and the research model. The results indicated that TAM was a good theoretical tool to understand students' acceptance of MALL. In addition, all constructs, with the exception of self-efficacy and interactivity, had significant effects on students' acceptance possibilities of MALL. Limitations and suggestions for the further study are also presented.

The success of iris recognition depends mainly on two factors: image acquisition and an iris recognition algorithm. In this study, we present a system that considers both factors and focuses on the latter. The proposed algorithm aims to find out the most efficient wavelet family and its coefficients for encoding the iris template of the experiment samples. The algorithm implemented in software performs segmentation, normalization, feature encoding, data storage, and matching. By using the Haar and Biorthogonal wavelet families at various levels feature encoding is performed by decomposing the normalized iris image. The vertical coefficient is encoded into the iris template and is stored in the database. The performance of the system is evaluated by using the number of degrees of freedom, False Reject Rate (FRR), False Accept Rate (FAR), and Equal Error Rate (EER) and the metrics show that the proposed algorithm can be employed for an iris recognition system.

The purpose of this paper was to discern the nature of socially acceptable corporal punishment through legal analysis. To do this, the researcher attempted to clarify the concept of corporal punishment, to figure out the current legal position about corporal punishment, and to examine the court cases against corporal punishment. The results of the study were as follows: Firstly, corporal punishment is intentional physical or emotional aversive stimuli to students who violated the rules and norms, to reduce or fix specific undesirable behaviors, by the person who is in charge of discipline of students. Secondly, current regulations do not accept corporal punishment in principle. Thirdly, court cases did not admit the corporal punishment in principle, but did not charge legal liability if the corporal punishment was done in proper manner in view of education. However, the judicial precedents are getting more strict focusing on the human rights of students.

According as IT environment changes from client/server system to the open system based on web service technologies, the exchange of data and services between independent applications and service servers in web environment is observed Recently. In this points, it is necessary that Geographic Information Systems, Spatial Imagery Information Systems, Intelligent Transportation Systems, and Global Navigation Satellite Systems based on the location and geometry information are inter-related each other. But, the inter-relation of these systems is very difficult because of the closed system architecture, different information format, and the absence of interoperability technologies. In this Paper, we describe 4S integration system based web service technologies that accept the international standard as WFS, WCS, WRS of OGC (OpenGIS Consortium) and UDDI, SOAP, WSDL of W3C. In detail, we study the system architecture design and implementation of traffic information service, routing service, and tracing service. These services are consisting of the data schema based on XML and GML, various functions of each layered service, each server platform, and web server. Specially, we represent that GML is being applied to a wide range of location-based services, telematics, and intelligent transportation

In many solute transport studies, either flux or resident concentration has been used. Choice of the concentration mode was dependent on the monitoring device in solute displacement experiments. It would be questionable, however. to accept the equivalency in the solute transport parameters between flux and resident concentrations in structured soils exhibiting preferential movement of solute. In this study, we investigate how they differ in the monitored breakthrough curves (BTCs) and transport parameters for a given boundary and flow condition by performing solute displacement experiments on a number of undisturbed soil columns. Both flux and resident concentrations have been simultaneously obtained by monitoring the effluent and resistance of the Horizontally-positioned TDR probes. The study reveals that soil columns having relatively high flux densities exhibited great differences in the degree of peak concentration and travel time of peak between flux and resident concentrations. The peak concentration in flux mode was several times higher than that in resident one. This was mainly due to the bypassing of solute through soil macropores.

There is a big issue to generate 3D hexahedral finite element (FE) model, since a process to divide the whole domain into several simple-shaped sub-domains is required before generating a continuous mesh with mapped mesh generators. In general, it is nearly impossible to set up proper division numbers interactively to keep mesh connectivity between sub-domains on a complicated arbitrary-shaped domain. If mesh continuity between sub-domains is not required in an analysis, this complicated process can be omitted. Element-free Galerkin method (EFGM) can accept discontinuous meshes, which only requires nodal information. However it is difficult to choose a reasonable influenced domain in moving least squares scheme with non-uniformly distributed nodes in discontinuous FE models. A new FE scheme fur discontinuous mesh is proposed in this paper by applying improved EFGM with some modification to derive FE approximated function in discontinuous parts. Its validity is evaluated on linear elastic problems.

The purpose of this study is to analyze the Daniel Libeskind' spatial concept in view of the Merleau-Ponty's Phenomenology. After the coming of postmodern architecture, the concept of space ceased to be discussed between architects. Instead a sign and a form were supposed as much more important subject to define architectural discipline. But after 1980, the new concept of architectural space was experimented by the architects like Frank Gehry, Peter Eisenman, Steven Hall, and Bernard Tschumi, which was clearly distinguished from modern spatial concept. By the Daniel Libeskind' architecture, this study are to make clear this tendency. For this, we accept as an important instrument Meleau-Ponty's phenomenology and the spatial concept of Minimalism, which stress the relationship of inter-subjectivity between space and human body. Consequently, Daniel Libeskind' spatial concept is characterized by fragmental, accidental, heterogeneous space by accidental events which is occurred by movement of human, which was indentified with Merleau-Ponty's spatial concept.

In this paper, a conceptual model of legal culture based on Ehrlich's "living law" theory and Cole's social-cultural explanation can explain the low utilization rates of arbitration of Japan and the high utilization rates of arbitration in the United States, simultaneously. This model highlights the clash between social norms and legal provisions in Japan. Japan has developed a two-tiered system of dispute resolution. At the official level, Japanese people accept the legal system imposed by the outside world. But, at a deeper level, they utilize diverse forms of informal dispute resolution mechanisms, such as reconcilement and conciliation, reflecting their own social norms. In contrast, there is no conflict between social norms and legal provisions in United States. This study may show that there are distinctions between American-style arbitration and Japanese-style arbitration, reflecting their own respective social norms. The question of reconciliation between the American style of arbitration and the Japanese style of arbitration can be resolved by an international arbitrator.
