This study identifies possible determinants that may have influences on the switching behavior from the current payment system of credit or check cards to the easy payment service based on push-pulling-mooring model. And this research empirically tests how those determinants affect switching intention to the easy payment service. The moderating effect of policy expectation is also taken into account. The findings show switching intention to the easy payment service is influenced by the followings: dissatisfaction with the current payment system as a pushing factor, perceived easy of use and trust in easy payment service as pulling factors, and affective/cognitive inertia and unfavorable subjective norm as mooring factors. The results also show that moderating effect of policy expectation exists in the relationship between perceived ubiquitousness and switching intention.

The 2008 world economic crisis had unprecedented consequences in European societies, with repercussions on Southern European countries in particular. In Italy, the crisis itself provided a plausible rationale for policy makers to push forward long needed welfare cuts, resulting in the neoliberal austerity trend fostered by the Monti government (years 2011-2012). In the light of the fact that Bismarckian welfare states from continental Europe are generally difficult to reform, understanding these policy dynamics requires an adequate theoretical framework. This paper seeks to understand the logics behind welfare reforms in Italy after the 2008 economic crisis, by reviewing available theoretical approaches in literature. It is argued that external forces (notably, the European Union) represented the main trigger factor, and that political elites marginalized the role played by civil society, with social problems such as unemployment worsening as a result.

The purpose of this study is to find out effective ways to take care of the 8th and 10th graders' disposition causing math. disliking. To accomplish this goal, we proceeded as follows : First we categorized the 11 factors recognized as the reasons of math. disliking into 4 math. disliking causes such as psychological f: environmental cause, conceptual cause, relational cause and application related cause. Second, to take care of these tow causes, we developed materials which are closely related with the contents of the 8th and 10th graders' school mathematics. Third with these materials we taught the students who had proved to have the math. disliking trend, for one semester. As a consequence of this experiment we arrived at the following results. As for psychological & environmental causes, 35.7% of the 8th graders and 17% of the 10th graders proved to have been improved significantly. This result shows that the curing of the psychological & environmental causes is more effective in the 8th graders than in the 10th graders. i.e., the curing effects of the students' psychological & environmental cause for disliking math. decline as they get older. As for conceptual causes, 35% of the 5th graders and 30% of the 10th graders proved to have been improved significantly. In case of the 8th graders this ratio was similar to that of the other causes. But as for the 10th graders this ratio was a little low compared with that of the case of relation causes and application related causes. As for relational causes, 35% of the 5th graders and 49% of the 10th graders proved to have been improved significantly. Especially the 10th graders improved greatly. Among the four factors that compose this cause, especially hierarchy and connection factors were effectively cured. On application related causes, 47% of the 5th graders and 57% of the 10th graders proved to have been cured significantly. And among the four types of causes listed above, this was the most successfully cured one. Of the two factors of this cause, the basic application factor appeared to have been improved in all experimental groups. In connection with teaching methods, we found out the followings two facts. First, the more teachers push students to solve their tasks with their own efforts, the higher is the ratio of owe. Second, the more teachers teach students personally, the more effective are the teaching results.

Recently, a massive loss of life and property is occurring in Korea due to traffic accidents, with the rapid increase in cars. For improvement of traffic safety, the Korea Transportation Safety Authority intensively analyzes accident data in local governments with low traffic safety index, performs a field investigation to extract problems and offers local governments improvements for problems, by conducting the 'Special Survey of Actual Conditions of Traffic Safety' each year, starting 2008. But local governments cannot strongly push forward the improvement projects due to the limited budget and the uncertainty of the improvement plan effects. Therefore, this study suggested a model which applied the Utility concept to the AHP theory, in order to efficiently decide a priority of the improvement plans in accident black spots in consideration of the limited budget of local governments. The number of accidents in each spot for improvement and accident severity, traffic volume, pedestrian volume, the improvement project cost and the accident reduction effect were chosen as evaluation factors for deciding a priority, and data about the improvement plan costs and the accident reduction effects, traffic accidents and traffic volume in the spots to undergo the special research on the real condition of traffic accident in the past were collected from the existing studies. Then, regression analysis was carried out and the Utility Curve of each evaluation factor was computed. Based on the AHP analysis findings, this study devised a priority decision method which calculated the weight and the utility function of each evaluation factor and compared the total utility values. The AHP analysis findings showed that among the evaluation factors, accident severity had the biggest importance and it was followed by the improvement plan cost, the number of accidents, the improvement effect, traffic volume and pedestrian volume. The calculated utility function shows a rise in utility, as the variables of the 5 evaluation factors; the number of accidents, accident severity, the improvement plan effect, traffic volume and pedestrian volume increase and a fall in utility, as the variables of the improvement plan cost increase, since the improvement plan cost is included in the budget spent by a local government.

SPIN90 was identified to farm molecular complex with $\betaPIX$, WASP and Nck. This complex shows that SPIN90 interacts with Nck in a manner dependent upon cell adhesion to extracellular matrix, but $SPIN90{\cdot}{\beta}PIX{\cdot}WASP$ complex was stable even in suspended cells. This suggests that SPIN90 serves as an adaptor molecule to recruit other proteins to Nck at focal adhesions. SPIN90 was phosphorylated by ERK1, which was, itself, activated by cell adhesion and platelet-derived growth factor. Such phosphorylation of SPIN90 likely promotes the interaction of the $SPIN90{\cdot}{\beta}PIX{\cdot}WASP$ complex and Nck. It thus appears that the interaction of the $SPIN90{\cdot}{\beta}PIX{\cdot}WASP$ complex with Nck is crucial for stable cell adhesion and can be dynamically modulated by SPIN90 phosphorylation that is dependent on cell adhesion and ERX activation. SPIN90 directly binds syndapin I, syndapin isoform II-1 and II-s via its PRD region in vitro, in vivo and also associates with endocytosis core components such as clathrin and dynamin. In neuron and fibroblast, SPIN90 colocalizes with syndapins as puntate form, consistent with a role for SPIN90 in clathrin-mediated endocytosis pathway. Overexpression of SPIN90 N-term inhibits receptor-mediated endocytosis. Interestingly, SPIN90 PRD, binding interface of syndapin, significantly blocks internalization of transferrin, demonstrating SPIN90 involvement in endocytosis in vivo by interacting syndapin. Depletion of endogenous SPIN90 by introducing $\alpha-SPIN90$ also blocks receptor-mediated endocytosis. Actin polymerization could generate farce facilitating the pinch-out event in endocytosis, detach newly formed endocytic vesicle from the plasma membrane or push out them via the cytosol on actin tails. Here we found that SPIN90 localizes to high actin turn over cortical area, actin-membrane interface and membrane ruffle in PDGF treated cells. Overexpression of SPIN90 has an effect on cortical actin rearrangement as filopodia induction and it is mediated by the Arp2/3 complex at cell periphery. Consistent with a role in actin organization, CFP-SPIN90 present in actin comet tail generated by PIP5 $kinase\gamma$ overexpression. Therefore this study suggests that SPIN90 is functional linker between endocytosis and actin cytoskeleton.

Shear friction strength model of concrete was proposed to explain the direct friction mechanism at the concrete interfaces intersecting two structural elements. The model was derived from a mechanism analysis based on the upper-bound theorem of concrete plasticity considering the effect of transverse reinforcement and applied axial loads on the shear strength at concrete interfaces. Concrete was modelled as a rigid-perfectly plastic material obeying modified Coulomb failure criteria. To allow the influence of concrete type and maximum aggregate size on the effectiveness strength of concrete, the stress-strain models proposed by Yang et al. and Hordijk were employed in compression and tension, respectively. From the conversion of these stress-strain models into rigidly perfect materials, the effectiveness factor for compression, ratio of effective tensile strength to compressive strength and angle of concrete friction were then mathematically generalized. The proposed shear friction strength model was compared with 91 push-off specimens compiled from the available literature. Unlike the existing equations or code equations, the proposed model possessed an application of diversity against various parameters. As a result, the mean and standard deviation of the ratios between experiments and predictions using the present model are 0.95 and 0.15, respectively, indicating a better accuracy and less variation than the other equations, regardless of concrete type, the amount of transverse reinforcement, and the magnitude of applied axial stresses.

The point-based complex event processing handled an instantaneous event by using one time stamp in each event. However, the activity period of the event plays the important role in the field which is the same as the finance, multimedia, medicine, and meteorology. The point-based event is insufficient for expressing the complex temporal relationship in this field. In the application field of the real-time world, the event has the period. The events more than two kinds can be temporally overlapped. In addition, one event can include the other event. The relation about the events of kind of these can not be successive like the point-based event. This thesis designs and implements the method detecting the patterns of the complex event by using the interval-based events. The interval-based events can express the overlapping relation between events. Furthermore, it can include the others. By using the end point of beginning and end point of the termination, the operator of interval-based events shows the interval-based events. It expresses the sequence of the interval-based events and can detect the complex event patterns. This thesis proposes the algorithm using the active instance stack in order to raise efficiency of detection of the complex event patterns. When comprising the event sequence, this thesis applies the window push down technique in order to reduce the number of intermediate results. It raises the utility factor of the running time and memory.

The issue presented in this paper are as follows: 1. Legislative actions of welfare-related law for the exceptional children. The legislative base for the evolution has been yet weak and ambigous at best for a formalization of what should be considered accepted practice and effective action in providing handicapped child and their parents educational rights and equal protection of the law. And they are under remote control of partial factor subject to social welfare law for children, and public law for education, promotion law for the exceptional child education, protection law for public aids. 2. Organization of government for the welfare services for the exceptional children. There is no sing of a push toward consolidation of effort for the welfare service of the exceptional children in this country that seeks to recapture a sense of unity, of coherence, of completeness from a reality made up of discontinuous fragments of humanitarian effora This presently that. as for the education of the exceptional child, by the section of the exceptional education in MOE (Ministry of Education), and/or as for welfare services and promotion actions, by the section of child welfare in MHSA (Ministry of Health and Social Affairs). One door type operation rooted in the specialization, and limited resources to evolve multi-purpose agencies that undertake to provide a broad range of tangible and concrete services, as well as supportive counselling and assessment, under a single management which plans and directs the allocations of resources, should be followed. 3. Facilities and recruitment of teachers for the exceptional children. In this country there are 54 facilities for special services, 56 schools for the exceptional education, and 3 colleges and equavalents that provide teacher training services leading to certification with IIO annual graduates. However, curriculum for exceptional children should be rearranged and reconstructed. Conclusion; Only as for social welfare institutions in community, this country produced a succession of specific purpose activities, over period of time, that accumulated to form the present network of hundreds of social welfare organizations and facilities Periodically major efforts were launched to revitalize or to improve the help-giving system. But they lack specialization to be effective, and the nature of multi-purpose center tends to be vague for the classified handicapped. Therefore, there, should be linkage between policy maker and community services to maintain some coherenty in preventive care, treatment, and after cares. At last, the effects of the current concept "the exceptional child" involved with their families, and their neighborhood should be considered in view of the people who consist about 25% of the total population.

Disability Discrimination Act(DDA) is generally recognized as the institutional frame to realize social model of disability. However social model is not automatically realized via the enactment of DDA. The realization of social model is influenced by various factors among which the definition of disability in DDA is very important factor. Paradoxically definitions of disability based on social model may push DDA into contradictory situation. This is caused by the fact that on the one hand definitions of based on social model exclude impairment and on the other hand they mixes characteristics and treatment. Because of these, when definitions of disability based on social model is reflected into definitions of disability in DDA, they may not be helpful to realize social model against original intention of advocates of the model. We can consider two approaches to resolve this paradox; one is to partially reform current definition of disability in DDA, the other is to totally amend current definition of disability. The former may pragmatic and worth to pursue but it cannot solve fundamental problems and may cause some new problems. The most consistent resolution with social model is to amend current definitions of disability into radically new one which excludes substantial limits and definition of disabled person from definition of disability. This new definition may called characteristics based definition or impairment based definition. Some people may think this new definition as one based on medical model but it is not. What we need is not to carve definition of disability based on social model into DDA but to make institutional frame for DDA to operate without contradictions and to develop social model of both impairment and disability. This model which does not exclude impairment could takes part in realization of the social model disability.
