  • Despite many numbers of studies in Technology Acceptance Model(TAM), the social influence construct has not been recognized, nor handled clearly. This study includes the social influence construct in TAM and tests the robustness of the model for different information systems contexts: office automation(spreadsheet) and Internet(WWW) usage. Study findings include that 1) social influence has a direct impact on the usage of spreadsheet, but not on Internet(WWW) usage, and 2) social influence has a stronger indirect impact on IS use through perceived ease of use than through perceived usefulness(for both Internet and spreadsheet).

  • The present paper extends the idea of tightened-normal-tightened sampling scheme to group acceptance sampling plans under the time truncated life tests. We consider three famous distributions that are widely used in the area of reliability such as the generalized exponential distribution, the Weibull distribution, and the Birnbaum-Saunders distribution in the proposed sampling plan. The plan parameters are determined such that the producer's risk and the consumer's risk are satisfied at the specified median life. Extensive tables showing plan parameters are provided at various values of the experiment time and the consumer's risk for each of three distributions for the practical use. Some examples are given to illustrate the procedure of the proposed plan.

  • Buckwheat flour was incorporated into steamed breads by adding the flour in the range of 0~9% based on the Baker's percentages and the physicochemical properties and consumer acceptance were investigated. After mixing, kneading, proofing, and molding, bread dough was steamed for 15 min using a steam tray and boiling water. The samples were cooled to room temperature for 15 min and packed in airtight bags for further analyses. pH of the steamed bread decreased slightly while titratable acidity increased significantly from 1.02 to 1.37 mL with the incorporation of more buckwheat flour in the formulation (p<0.05). Water activity was not affected by the buckwheat flour level (p>0.05). Moisture content slightly decreased from 43.72 to 42.30% while soluble solids content increased from 0.63 to 0.85 as the buckwheat flour concentration increased. As a result of the addition of buckwheat flour, the specific volume decreased from 3.31 to 2.57 mL/g; on the other hand, the spread ratio ranged from 2.17 to 2.21 without significant differences among them (p>0.05). At the higher level of buckwheat content, lower scores of all color parameters ($L^*$, $a^*$, and $b^*$-values) were observed. Firmness increased significantly with an increase in buckwheat flour content (p<0.05). Consumer acceptance tests indicated that incorporation of up to 3% buckwheat flour in the formulation of steamed breads did not significantly influence the consumers' acceptability in all attributes tested, except for color and elasticity.

  • This study is progressed for understanding of the acceptance intention differentiated through the view of smart phone non-user's adopting plan. And the research model is proposed in the view of new technology adopting, Innovation Diffusion Theory, Rogers 1995, and Technology Acceptance Model, Davis 1989. In the survey, SPSS 18.0 and AMOS 18.0 are used to analyze the 685 smart phone non-users data. The results of the feasibility analysis and the factor analysis show the measured variables determined in the statistical significant range. Also, 11 hypotheses, among the 16 hypotheses, are adopted by the hypothesis tests through the path analysis, one-way-ANOVA and hierarchial regression analysis. The results indicate variables affect on the non-smart phone user's adopting intention. The primary factor is the perceived usefulness, secondary factor is the social property, and the rest is the playfulness. And, the primary adoption factor is affected to early majority and late majority among each innovation adopters.

  • The current study tests the effect of fashion product knowledge and confidence in fashion coordination on innovative fashion product acceptance, mediated by creative fashion consumer efficacy. Creative fashion consumer efficacy refers to a consumers' belief in the ability to consume fashion products in a creative way. The survey was conducted on 474 people between 20 and 40 years of age in a panel of online survey firms. Data was analyzed using reliability analysis and frequency analysis by SPSS 20.0 along with confirmatory factor analysis and structural equation modeling done by AMOS 20.0. The results reveal that creative fashion consumer efficacy consists of original thinking efficacy, usage expansion efficacy, problem solving efficacy, and method variation efficacy that is consistent with the original structure of creative consumption efficacy. In addition, fashion product knowledge and confidence in fashion coordination do not affect innovative fashion product acceptance. The effects of fashion product knowledge and confidence in fashion coordination on innovative fashion product acceptance are fully mediated through creative fashion consumer efficacy. The results of this study demonstrate that people who are knowledgeable, confident and associated with fashion product consumption can have a high level of creative fashion consumer efficacy that increases innovative fashion product acceptance.

  • This paper proposes strain-based acceptance criteria for assessing plastic instability of the safety class 1 nuclear components made of ferritic steel during level D service loads. The strain-based criteria were proposed with two approaches: (1) a section average approach and (2) a critical location approach. Both approaches were based on the damage initiation point corresponding to the maximum load-carrying capability point instead of the fracture point via tensile tests and finite element analysis (FEA) for the notched specimen under uni-axial tensile loading. The two proposed criteria were reviewed from the viewpoint of design practice and philosophy to select a more appropriate criterion. As a result of the review, it was found that the section average approach is more appropriate than the critical location approach from the viewpoint of design practice and philosophy. Finally, the criterion based on the section average approach was applied to a simplified reactor pressure vessel (RPV) outlet nozzle subject to SSE loads. The application shows that the strain-based acceptance criteria can consider cumulative damages caused by the sequential loads unlike the stress-based acceptance criteria and can reduce the overconservatism of the stress-based acceptance criteria, which often occurs for level D service loads.

  • Generally, in the temperature and environment test of railway electronics, cold and heat resistant tests are involved. Relevant KRS standards describe "There is no problem" as acceptance criteria for function check during the temperature and environment tests. According to this requirement, testers perform some function and performance tests which are easy to perform during test procedure using temperature chamber. This paper reviews the limit of current check method for cold and heat resistant tests and proposes an alternative. An alternative is the application of data sheet. Using data sheet, the temperature of equipped components is checked whether this temperature meet acceptance criteria or not. Also, this paper suggests temperature test range guidelines comparing temperature standards for general IC component. For the example in real field, this method uses the lowest temperature and the highest temperature in major domestic cities.

  • The image intensifier is the key component which determines the imaging characteristics in a fluoroscopic imaging system. A system performance program for clinical evaluation of two image intensifiers, that is simple, non-invasive and time effective, was described. Tests were grouped into three headings: x-ray generator, image quality, and collimation. For the x-ray generator, the kVp accuracy and the automatic exposure control operation were compared. Low- and high-contrast resolution measurements, and mesh pattern study belong to the image quality tests and those tests were performed for the video monitor and photospot images. For the collimation, usable field diameter and image distortion of image intensifiers were measured and quantified. The procedures and the results are hoped to be used for the clinical evaluation of system performance and/or acceptance tests for image intensifiers.

  • The application of the knowledge from the Human Genome Project to clinical medicine will be through both industrial drug development and the application of pharmacogenomics (PG) to patient care. The slow uptake of clinical innovations into clinical practice can be frustrating, but understanding the history of acceptance and sustaining medical innovation is critically important to position PG to succeed. This primarily means that PG tests must have legitimacy; they must be thoroughly validated, must be cost-effective, must be widely accepted by medical practitioners, must be supported by public policy, and must have a way of being easily incorporated into current medical practice. They must also lead to actionalble decisions by health care providers for their patients. Innovative PG assays should be tested in the best US laboratories, and reimbursement for testing must be accepted at the federal and state level. The companies providing these PG tests should be capable of supporting the interpretation and use of the test throughout medical practice. Advances such as the addition of PG information to drug labeling and the routine use of validated biomarkers to determine choice of cancer chemotherapy have been made. The PG research community must pay attention to the principles that have been previously described for acceptance and sustaining medical innovations in order for PG to be widely accepted in clinical medical practice.
