Purpose - The study aims to investigate the effects of ethical management on corporate image and purchase intention. Research design, data, and methodology - The study employs monthly time series data from October 2013 to November 2013, analyzing variables to verify hypotheses. These concern three questions on marketing communication, five on public interest business activities, four on donation & sponsorship, two on donation & sponsorship activities, six on corporate image, four on volunteer service, and five on demographic characteristics. Results - Hypothesis 1, "Ethical management in marketing communication, public interest business, donation & sponsorship, and volunteer service positively affects corporate image," was partially adopted with significant regression of marketing communication, public interest business activity, and donation & sponsorship. Hypothesis 2, "Ethical management such as marketing communication, public interest business, donation & sponsorship, and volunteer service positively affects purchase intention," was partially adopted with significant regression of marketing communication and public interest business. Hypothesis 3, "Corporate image positively affects purchase intention," was adopted at significant regression. Conclusions - Ethical management influenced purchase intention and corporate image.

There has been a recent increase in the interest towards founding companies and in line with the South Korean Government's policy on start-up support, discussions are rife about the effect of entrepreneurship on the management and performances of these companies. To enhance the competitiveness of SMEs, it is expedient to acquire and deploy consistent entrepreneurship, differentiate corporate resources, ensure the appropriate utilization of resources and the integration of such factors in response to the changing environment. This research examines relationships among entrepreneurship, three components of corporate capabilities, dynamic capability and technical performance based on resource-based view and the dynamic capability theory. The authors also investigate the moderating role of corporate life cycle. To test the hypothesis, we conducted a survey on 352 technologies -innovative SMEs located in South Korea via professional research institutes. The findings confirm the hypothesis that SMEs' entrepreneurship has a positive effect on three kinds of corporate capabilities (e.g., marketing, R&D, operations capability), and it had a positive effect on dynamic capability, whiles dynamic capability also had an influence on technical performances. The findings also confirmed the hypothesis that corporate life cycle moderates the relationship between dynamic capability and technical performances respectively. The research implications for both practitioners and academicians are discussed.

Due to industrial development, the importance of GD&T tolerance is growing day by day. Roundness measurement means the size deviated from the ideal circle. Roundness evaluation methods include LSCI, MZCI, MCCI, and MICI. Generally, A is used a lot at industrial evaluation. In this experiment, we studied the variations in table velocity, filter values, and detector angles, which can cause errors in roundness measurements. The measurement conditions were table speeds of 10, 30 and 60 mm/s, probe angles of 10, 20 and 30 degrees and frequency filter settings of 15, 150 and 500 upr and The number of experiments was measured 30 and the average value was chosen as a representative value. The hypothesis test showed that the p-value for the frequency filter was greater than 0.05, and the experiment rejected the null hypothesis and adopted the alternative hypothesis.

The study on the critical success factors (CSF) for electronic commerce systems has been a hot topic in both academe and industry. On the basis of reviewing papers on CSF and analyzing their problems, this paper designs the initial assessment indictors and website features and functions influencing EC success. Using Delphi survey and data analysis, we get the five important assessment indictors and seven important web features and functions. Furthermore, the hypothesis of CSF model is proposed. Finally, we conduct a survey on the Chinese Publishing Industry to test the hypothesis. The result shows that the hypothesis is partly supported, which means useful and understandable information, complete and timely information, credible and accurate information, all product-related information are the critical success factors for EC publishing industry. This research not only impels EC research in China, but also has instructional effect on the implementation of EC for enterprises to increase the success rate of EC.

This paper compares income and consumption for their relative effectiveness in measuring inequality. Although income inequality has received more attention in the literature, the permanent income hypothesis links consumption to welfare more directly than income. To the extent economic agents smooth their consumptions, consumption inequality is a better indicator for an economy's welfare inequality, and it is especially so when income volatility is high. The empirical analysis in this paper indicates that the income and consumption patterns among the Korean wage/salary worker households are quite consistent with the permanent income hypothesis. Further, it is found that consumption inequality tends to be lower than income inequality, and more importantly, that the two inequalities do not always vary in the same direction. These results call for stronger emphasis on consumption inequality in inequality literature.

The purposes of this study were to understand the influence of customer perceptions of corporate social responsibility (CSR) activities in family restaurants on customer trust and satisfaction. Based on results form 395 family restaurant patrons obtained empirically, we reviewed the reliability and fitness of a research model and verified two hypotheses using the AMOS program. The hypothesized relationships in the model were simultaneously tested using a structural equation model (SEM). Hypothesis 1, which hypothesized a positive relationship between customer perception of CSR activities and customer trust was partially supported. Additionally, hypothesis 2, in which customer perception of CSR activities had significant positive effects on customer satisfaction, and customer trust had significant positive effect on customer satisfaction (Hypothesis 3 was supported). Finally, customer trust performed a partial role as a parameter in the causality between CSR activity in the family restaurant and customer satisfaction. Limitations and future research directions are also discussed.

Model verification and validation (V&V) is a current research topic to build computational models with high predictive capability by addressing the general concepts, processes and statistical techniques. The hypothesis test for validity check is one of the model validation techniques and gives a guideline to evaluate the validity of a computational model when limited experimental data only exist due to restricted test resources (e.g., time and budget). The hypothesis test for validity check mainly employ Type I error, the risk of rejecting the valid computational model, for the validity evaluation since quantification of Type II error is not feasible for model validation. However, Type II error, the risk of accepting invalid computational model, should be importantly considered for an engineered products having high risk on predicted results. This paper proposes a technique named as the response-adaptive experimental design to reduce Type II error by adaptively designing experimental conditions for the validation experiment. A tire tread block problem and a numerical example are employed to show the effectiveness of the response-adaptive experimental design for the validity evaluation.

It seems certain that even if the same evidence is in itself given for any hypotheses, the way how it is obtained makes some differences in its support degree of them. In this respect, it is worth paying our attention to Mayo's conception of "severe test" and her technical development of it, which are just concerned with the procedures of getting evidence. Nonetheless, there have been criticisms against her theory from various respects. Among them, here this paper focuses on those especially raised by Jung (2018) and Iseda (1999). And it attempts to defend Mayo's theory on behalf of her against their critiques. For this purpose, the paper also proposes particularly a new concept of what is called the "mechanism generating an evidence-hypothesis". On the way, Mayo's own faults are revealed as well.

Purpose: The purpose of this study was to develop a play education program to reduce children's fear of needle insertion to the implanted port, and to assess the effect of this program. Method: The play education program was composed of play education before needle insertion, encouragement during needle insertion, and a present to reward then after needle insertion. Measurement instruments were the Procedure Behavior Check List(PBCL) and Faces Rating Scale(FRS). Results: The first hypothesis, "the PBCL point of children with malignant disease would decrease after play education program", was rejected(before insertion : Z=-0.189, p= .850, during insertion : Z=-0.350. p= .727, after insertion : Z=-0.590, p= .555). The second hypothesis, "the FRS point of children with malignant disease would decrease after play education program education", was rejected(observer 1 : Z=-0.245, p= .806, observer 2 : Z=-0.912, p= .362, self-report : Z=-0.181, p= .856). The third hypothesis, "the Time of needle insertion would decrease after play education program", was rejected(Z=-0.464, p= .642). Conclusion: The effect on fear-reduction of play education program for children with malignant disease inserted implanted port was not significant but continuous education is needed for parents and children.

This study is attempting to examine the possible determinants of the rise of the sex ratio at birth from 106 to 110 in past decade in Taiwan. The basic hypothesis for the sudden rise of the sex ratio at birth is due to a combination of prenatal sex determination and abortion. The reasoning for this hypothesis involves three types of considerations - motivation, norm, and access. The theory is evaluated by analyzing data from birth registration and a large and representative sampie of Taiwanese wives of childbearing age. The empirical data seem to support the theoretical preposition and the basic hypothesis that the rise of the sex ratio at birth in Taiwan is due to a combination of prenatal sex determination and abortion. There is striking evidence of son-preference in the rise of the sex ratio at birth in higher birth order. In 1990 the sex ratio was 119 for third births and 128 for fourth and fifth births compared to the expected 106. Also, the 1991 KAP data indicated that women who have only daughters but no any son are more likely to make prenatal sex screening and terminate their pregnancies in male live births at higher birth order. Obviously, genetic diagnosis through chorionic villus sampling which was available in recent years was misused for prenatal sex determination and sex selective abortion.
