The purpose of this study was to investigate the relationship between information quality, Online Travel Agency (OTA) trust, and continuous usage intention provided by OTA through the application of the SOR(Stimulus-Organism-Response) model. To achieve the purpose of the study, 234 responses were used for analysis, and the hypotheses were tested through the SPSS v.21 program and AMOS v.21 programs. The research results can be classified into the following three categories. First, it was determined that accuracy, timeliness, and usefulness among the factors for information quality had a significant positive effect on OTA trust and continuous usage intention. Second, it was determined that OTA trust was found to have a significant positive effect on continuous usage intention. Third, it was determined that OTA trust had an indirect effect on the relationship between accuracy, timeliness, usefulness, and continuous usage intention among the factors for information quality. This study looked at the lower dimension of information quality, which was insufficient in the field of OTA. This study can be used as basic data to, in practice, build a user-centered informational provision environment by identifying the factors that promote the continuous usage intention of consumers, which is linked to the revenue of online travel agencies.

The purpose of this study is to analyze and compare dental hygine curriculum of three countries--Korea, U.S.A., and Japan--, focusing on the ways of organizing content. In this study, 30 curriculum documents of dental hygienist in U.S., Japan, and Korea were analyzed and discussed by a framework of analysis which was constructed referring to Tylerian curriculum model. Using this framework, three kinds of key components of curriculum document were compared according to specific elements of each component. More specifically, comparing those curriculum documents, we must consider the dimension of content organization. In this study, the problem of course organization was viewed on three dimensions: continuity, sequence, and integration of curriculum content. Based on the results of this study, the conclusions are as follows. 1. Courses of dental hygienist education should be organized so that the curriculum foster the cumulative and continuous learning. It will be accomplished by considering the essential procedures or sequence of dental hygiene activities. 2. When organizing curriculum elements, we should consider the continuity dimension of learning content. Continuity deals with the vertical manipulation or repetition of curriculum components. In other words, it accounts for the reappearance in the curriculum of certain major ideas or skills. Therefore, courses should be based on the level of the dental hygienist activities in order to ensure a continuity of learning experiences. 3. Dental hygienist curriculum must be organized in a way to integrate the logic of dental hygiene as a discipline with the process of dental hygiene performance. Integration refers to the linking of all types of knowledge and experiences contained within the curriculum design. It emphasizes horizontal relations among various content topics and themes involving all domains of knowledge recognized. Thus, courses of dental hygiene curriculum should be integrated to allow college students to obtain a unified view of knowledge and an in-depth meaning of the dental hygiene as a profession.

Backgrounds and objective : EEG reflect dynamic changes of continuous neuronal activities by internal and external stimuli. The aim of this study is to quantify nonlinearly the local dynamic differences among EEG data corresponding to different states of brain. Methods : EEG was recorded from twelve healthy normal subjects(mean age, 29.7 years; 8 men and 4 women) using digital EEG machine. 18-channel EEG data were selected during eyes closed(EC), eyes open(EO), and mental arithmetic(MA) in each subject. Correlation dimension(D2) and largest Lyapunov exponent(LLE) were calculated from three states and average value was mapped 2 dimensionally and compared with each other. Results : The distribution of D2 was relatively symmetric and its value was higher in frontal than in parieto-occipital region during EC. These findings were reversed during EO. Bilateral centro-temporo-parietal region showed high D2 value in MA compared with those in EC, which was more prominent in left side. LLE was larger than zero in all state and showed significant differences among EC, EO and MA(p=0.000). Conclusion : These results suggest that nonlinear analysis of EEG can quantify dynamic state of brain.

In the rapidly changing information age, as the need for Informatization education increases, it is necessary to further activate Informatization education for adults. First, in terms of lifelong learning, this researcher suggested learner analysis, class subject materialization, and lecture environment confirmation as three things to be considered first before the course is opened. And as a matter to be continuously considered in terms of lifelong learning, this researcher considered that the connection with the next quarter class and the continuity of learning opportunities should be considered. This study attempted to reveal the differentiated characteristics of informatization education in terms of lifelong education by presenting and analyzing three actual class cases taught by this researcher at lifelong education institutions. Its characteristics included customized education in the information age, continuous upgrades of equipment, instructor education in response to the information age, and expansion of employment opportunities. Based on the case of information education classes, this study, which analyzed the differentiated characteristics of information education at the lifelong education level, can help improve the quality of instructors and self-development of learners in the actual educational environment. For this, continuous follow-up research will also be needed.

In this paper, we investigates the benefits of using social media on intentions and implementation entrepreneurial. This study took place in a well-known vocational college in Bandung, Indonesia, from July 2020 to January 2021. The research method used was the explanatory survey. Research data obtained from 317 respondent. Factor analysis and multiple regression were used to analyze the data. According to this study, social media has three dimensions: ease of use, controllability, usability, and profit. Entrepreneurial intention is made up of two components: entrepreneurial motive and entrepreneurial effort. Furthermore, there are four components to entrepreneurship implementation: investment courage, technology tools, social media skills, and environmental support. Other findings of each dimension of social media proved to affect entrepreneurial intention positively. The four aspects of entrepreneurial execution were likewise positively influenced by the dimension of entrepreneurial intention. This research reveals that students make the most use of the technologies available on social media for business and interactively communicate with their customers. Therefore, social media plays a role in accelerating the growth of entrepreneurship among students. However, more research is needed to see if there is a continuous pattern in the findings of this study so that the findings can be generalized.

The purpose of this study was to identify the constructive principle and techniques of Vionnet's works. According to analysis of Vionnets works, it was found that Vionnet conceived of the human body as a continuous shaping of a cylinder. Vionnet's drapery denied the planner presumption of woman and gave real three-dimension to form and to fashion. The techniques of Vionnet's works were as fallow : (1) She introduced the diogonal "bias cut" and changed dress design by her sensuous use of fabrics. (2) She eliminated interfacing to keep the silhouette and the fabric soft. (3) She manipulated the fabric to remove the excess for fit and decoration at the same time. (4) She treated the fabric with a synthesis of geometry and grace. (5) The sale luxury allowed was to note the choice of seams, facings, hems, and stitches. (6) Vionnet's dresses were not lined.

Flexible pavement responses to vehicular loading, such as critical stresses and strains, in each pavement layer, could be predicted by the multilayered elastic analysis. However, multilayered elastic theory suffers from major drawbacks including spatial dimension of a numerical model, material properties considered in the analysis, boundary conditions, and ill-presentation of tire-pavement contact shape and stresses. To overcome these shortcomings, three-dimensional finite element (3D FE) models are developed and numerical analyses are conducted to calculate pavement responses to moving load in this study. This paper introduces a methodology for an effective 3D FE to simulate flexible pavement structure. It also discusses the mesh development and boundary condition analysis. Sensitivity analyses of flexible pavement response to loading are conducted. The infinite boundary conditions and time-dependent history of calculated pavement responses are considered in the analysis. This study found that the outcome of 3D FE implicit dynamic analysis of flexible pavement that utilizes appropriate boundary conditions, continuous moving load, viscoelastic hot-mix asphalt model is comparable to field measurements.

Objective Categorical syndrome such as schizophrenia could be the complex of many continuous mental structure phenotypes including several personality development/degeneration dimensions. This is the study to search heritability and familiality of MMPI personality dimensions in the Korean schizophrenic LD (Linkage Disequilibrium) families. Methods We have recruited 204 probands (with schizophrenia) with their parents and siblings whenever possible. We have used MMPI questionnaires for measuring personality and symptomatic dimensions. Heritabilities of personality dimensions in total 543 family members were estimated using Sequential Oligogenic Linkage Analysis Routines (SOLAR). Personality dimensions in total family members were compared with those in 307 healthy unrelated controls for measuring the familialities using ANOVA analysis. Results Seven of the 10 MMPI variables were significantly heritable and were included in the subsequent analyses. The three groups (control, unaffected 1st degree relative, case) were found to be significantly different with the expected order of average group scores for all heritable dimensions. Conclusion Our results show that the aberrations in several personality dimensions could form the complexity of schizophrenic syndrome as a result of genetic-environment coactions or interactions in spite of some limitations (recruited family, phenotyping).

Recently, advance on various modalities of diagnosing, prostate volume estimation became possible not only by the existing two-dimension medical images data but also by the three-dimensional medical images data. In this study, magnetic resonance image (MRI), computer tomography (CT) and ultrasound (US) were employed to evaluate prostate phantom volume measurements for estimation, comparison and analysis. For the prostate phantoms aimed at estimating the volume, total of 17 models were developed by using devils-tongue jelly and changing each of the 5ml of capacity from 20ml to 100ml. For the volume estimation through 2D US, the calculation of the diameter with C9-5Mhz transducer was conducted by ellipsoid formula. For the volume estimation through 3D US, the Qlab software (Philips Medical) was used to calculate the volume data estimated by 3D9-3Mhz transducer. Moreover, the images by 16 channels CT and 1.5 Tesla MRI were added by the method of continuous cross-section addition and each of imaginary prostate model's volume was yielded. In the statistical analysis for comparing the availability of volume estimation, the correlation coefficient (r) was more than 0.9 for all indicating that there were highly correlated, and there were not statistically significant difference between each of the correlation coefficient (p=0.001). Therefore, the estimation of prostate phantom volume using three-dimensional modalities of diagnosing was quite closed to the actual estimation.
