  • 1. Objectives This study focuses on the reliability of the Questionnaire about Sasang Constitution Classification for Mongolians 2. Methods Test-retest method and internal consistency method have been performed based on the absolutely diagnosed group of 87 cases who respond to the questionaries during the time interval of one yeat between July 2003 and July 2004 to verify the confidence level. 3. Results and Conclusions (1) In the test-retest for each question of the Questionnaire of Sasang Constitution Classification for Mongolians, the dependency ratio is 40% and the agreement ratio is 92%. Therefore, this questionnaire has credibility because it has question relations and high agreement ratio. (2) In the internal consistency method for the measure of the Questionnaire of Sasang Constitution Classification for Mongolians, the value of Cronbach alpha is mote than 0.60. As a result, this questionnaire has internal consistency for each question which explains each physical constitution and it has credibility (3) In the internal consistency method for the measure of the Questionnaire of Sasang Constitution Classification for Mongolians, the Pearson's correlation coefficient, r, falls between $+0.38\;{\sim}\;+0.54$ in each measure. Accordingly, this questionnaire has internal consistency between each physical constitution measure and it has credibility.

  • In the 21st century, the roles of UGV in the ground battle draw its attention and many research about how to use it is going on globally, but not many study is doing about how to measure its combat effectiveness in the battle. Basically, the effectiveness of UGV is different from its mission profile. Hence, we proposed Measures Of Effectiveness which can measure the UGV effectiveness based on five different missions such as mine detection, nbc detection, reconnaissance, rescue, and fire mission. We expect that these Measures Of Effectiveness proposed are able to contribute to increase the credibility of the study results for UGV effectiveness. We also hope that this paper can stimulate to expand the research scope and related field about UGV effectiveness in the future.

  • In possibility framework, we propose two risk measures named Fuzzy Value-at-Risk and Fuzzy Conditional Value-at-Risk, based on Credibility measure. Two portfolio optimization models for fuzzy portfolio selection problems are formulated. Then a chaos genetic algorithm based on fuzzy simulation is designed, and finally computational results show that the two risk measures can play a role in possibility space similar to Value-at-Risk and Conditional Value-at-Risk in probability space.

  • Firms increasingly utilize Social Networking Service(SNS) to lead user's voluntary behavior. In the web-based environment, users show coexist loyal behavior which is represented by 'web-based pro-organization citizenship behavior' and 'anti-citizenship behavior'. To measure genuine performance of web-activity, we separated degree of compliance based on credibility, 'deep-level' and 'surface-level' to comprehend different behavior after compliance. The analysis result shows that contents credibility is important to enhance deep-level of compliance which has significant influence on web-based pro-organization citizenship behavior. Contrastively, surface-level of compliance has influence on anti-citizenship behavior. Based on the results of these analyses, the directions of web-based activities for the common good and self-interests of the stakeholders of the web-based activities will be proposed.

  • 본 연구에서는 한의학 관련 웹 사이트의 콘텐츠를 객관적인 신뢰성의 관점에서 분석함으로써, 한의학 웹 사이트의 질적 평가의 핵심인 신뢰성을 측정하는 것이다. 이를 위해서 한의학의 대표적인 53개 사이트의 일반적인 특성과 신뢰성 관련 요인을 정성적으로 분석하였다. 먼저 사이트의 일반적인 특성을 파악하기 위해서 사이트 운영상태, 핵심 제공 서비스 종류 등 4가지 항목을 조사하였다. 그리고 신뢰성 평가를 위해서 전문성 요인, 믿음성 요인 등 4가지 항목으로 구성된 평가지표를 적용하여 사이트의 신뢰성에 가장 큰 영향을 미치는 요인을 도출하였다. 사이트별 신뢰성 값은 '경희의료원' 사이트가 2.907로써 가장 높은 신뢰성을 나타냈으며 '이상훈 쉬운 한의학 이야기' 사이트가 -0.268로써 가장 낮은 신뢰성을 보였다. 이 결과는 개발자에게는 한의학 웹 사이트의 개선방향에 대한 기본 자료로 활용될 수 있으며, 일반 인터넷 사용자에게는 한의학 웹 사이트에 대한 객관적인 신뢰도를 확인 할 수 있는 기준으로 활용될 수 있을 것이다.

  • Combination of AHP priorities is essential in combining opinions of multiple experts. There are two ways to get combined priorities: one is to combine the pairwise matrices and obtain the priority from it and another is to combine the individual priorities. In this paper, we use a Dirichlet probability model to combine the priorities from multiple experts. The resulting combined priority is an expected value of the model, which is a function of some measure of the homogeneity and credibility of the group of experts. We give some interpretations of this measure and illustrate them by numerical example.

  • 손해보험의 신뢰도이론에서 순보험료로 사용되는 베이즈보험료는 꼬리위험을 반영하지 못한다는 한계점이 있다. 본 논문에서는 꼬리위험측도를 이용하여 할증보험료를 결정하는데 있어 중요하다고 여겨지는 두 가지 주제를 다루었다. 첫째, 위험측도로부터 유도되는 안전할증은 내재된 담보의 위험을 보다 정확히 반영할 수 있으며, 동시에 베이즈보험료만을 사용할 경우 초래될 수 있는 잘못된 의사결정을 피할 수 있음을 보였다. 둘째, 동일한 사전분포가 주어지더라도 서로 다른 조건부손실분포의 꼬리위험 순위와 그에 상응하는 예측분포의 꼬리위험순위는 일반적으로 다를 수 있음을 모수적 모형에 기반하여 보였다. 따라서 안전할증은 조건부손실분포의 위험측도가 아니라 예측분포의 위험측도를 사용해야 함을 알 수 있다.

  • Our study adopted ELM (Elaboration Likelihood Model) to measure the impact of central and peripheral cues on e-healthcare website behavior and its consequence on perceived loyalty of users. While most of ELM studies did not elaborate the antecedent of both central and peripheral cues, we measured the antecedents of those information processing routes to clarify how technical and quality factors (i.e. information organization, security concern, and website attractiveness) develop the nature of either central or peripheral route. We found that information organization was the main antecedent of information quality presented on the website. Second, the results revealed that website security has a positive effect on website credibility. Third, we also found that website attractiveness was positively associated with website credibility. Fourth, consistent with elaboration likelihood model, the empirical findings suggested that information quality (central cue) and website credibility (peripheral cue) were strong predictors of behavior intention to use health website. Our findings also suggested that behavior intention to use health website significantly influenced perceived loyalty.

  • The article reviews the quality of information on the Internet in general and health information in particular, where the accumulation and steady increase of information available on the Internet, without concern for its quality or importance, and regardless of the target audience, in addition to the lack of evidence of its credibility such as the availability of the name of the editor and references, and the availability of the name of an academic or research body responsible for that information. Add to this the lack of bibliographic data that can help infer the novelty of the information, and verify the element of trust in it . The problem is exacerbated with regard to the health information available on the Internet, due to its danger resulting from the presence of false health information that may cause danger to human health if relied upon. Through this article, the researcher proposes criteria that can help users search for information to measure the degree of quality, trust, and credibility of information in general and health information available on the Internet in particular.

  • Under exhibition circumstances, exhibition advertising by organizer is a mean to promote exhibition service to exhibitors and visitors while general advertising is to promote products and services to consumers. The objective of this research is to suggest advertising strategies by seeing differences in the impact of information quality and media credibility on visitor intention depending on the types of exhibition. This study adopted Elaboration Likelihood Model to measure the impact of central and peripheral cues on advertising attitude and its consequence on visitor intention. We further examined how these influence processes were moderated by exhibition types of B2B and B2C. We conducted survey from B2B and B2C exhibitions respectively, and analyzed structural equation model and moderator regression. We found that first, among factors of information quality as a central cue, argument strength has a positive impact on attitude towards advertising. Second, we also found among factors of media credibility as a peripheral cue, media trustworthiness has a positive impact on attitude towards advertising. Lastly, this study revealed that a type of exhibition moderates the central and peripheral routes towards advertising attitude, showing that B2C visitors are influenced by factors of information quality, and B2B visitors rather by media credibility. This study yields implications in that it gives marketers of organizer a background to set different marketing strategies depending on the types of exhibition.
