Purpose - This study investigated relationship quality and/or loyalty, from the viewpoint that merchants and consumers could develop the traditional market. It reorganized variables to find the conditions of values that could stimulate consumers' motives to revive the traditional market. Research Design, data, and methodology - This study employed 202 copies of effective questionnaires, based on the data of Yang & Ju (2012), to conduct correlation, regression, and structured equation modeling (SEM). Results - The results emphasized product and store atmosphere as store selection attributes to consider in the minimum error correction (MEC) model; service factor was not significant. Further, consumers valued relationship quality in the test of mediated effects of the sub-factors of store selection attributes, including consumers' social and emotional value. The relationship quality significantly influenced consumers' value in traditional markets that needed to improve and develop using several variables. Conclusions - This study revealed connections between attributes, consequences, and values using the causal relation model, to generate an optimal model based on a practical and theoretical background and proposed ways to obtain consumer-related information easily.

국방기술품질원에서 1999년부터 수행중인 품질위험도 평가 기법은 하자발생 가능성이 높은 취약업체 또는 취약품목을 식별하는데 제한적이라는 평가를 받고 있다. 이 연구는 AHP 기법을 통해 평가요소의 중요도를 재 산정한 평가모형을 제시한다. 개선된 평가배점의 타당성을 검증하기 위해 2005년도 하자발생 품목의 위험도 평가결과에 적용하여 평가점수 및 위험도의 변화를 분석하였다. 개선된 평가모형은 기존의 평가배점 방법 보다 고 중 위험도 품목을 더 많이 식별해 낼 수 있었으며 업체위험도가 품목위험도보다 더 중요한 것으로 나타났다. 업체위험도에서는 전문능력과 생산실적, 품목위험도에서는 제품특성 평가요소가 상당히 중요한 것으로 평가되었다. 고 위험도로 분류된 업체는 품질에 있어 집중관리를 받게 됨으로 하자 발생의 가능성이 더 줄어들 수 있을 것이다.

The present study is aimed at assessing medical service quality as perceived by in-patients of geriatric hospitals and at analyzing the excitement factors by using revised IPA Applying the Kano's model for users' satisfaction. The data was collected from Nov. 5 to Dec. 7, 2012. Among a total of 503 cases of questionaries, only 419 cases were used. To data were analyzed by PASW statistics 18.0 and revised IPA applying Kano's model. The paired t-test results reveal that satisfaction was higher than the expectation level at a statistically significant level across all the medical service quality factors. The revised IPA results categorized facility convenience, hospitalization and care, and kindness as basic factors and medical reliability and access as excitement factors. In conclusion, medical reliability and access, which were identified as excitement factors of medical service quality, are essential opportunity factors for users and should accordingly be used as strategic factors to increase satisfaction with a geriatric hospital and induce customer surprise.

This research aims to construct a model that combines brand love, brand loyalty, brand image, customer satisfaction, and service quality into a single model, with brand loyalty coming foremost, and test its predictive power in building brand love. Moreover, mediating effect of customer satisfaction and brand image on service quality and brand loyalty affecting brand love was checked. The study adopted an alliance context using an existing SERVQUAL model, a bi-dimensional aspect of brand loyalty and parasocial love relationship theory, to identify brand love as a construct or outcome in the consumer-brand relationship. Using a quantitative approach, survey questionnaires were distributed by unrestricted random sampling among 507 Saudia Airlines customers. Data were analyzed using structural equation modeling with SmartPLS 3.0. The results revealed significant relationships between four variables except for the brand image. It was found that brand image had no mediating effect on the relationship between service quality and customer loyalty. The outcome of this study highlights the importance of airline alliances for service quality, which leads to positive customer satisfaction, brand image, and customer loyalty. A unique contribution of the study is that it revealed that brand loyalty is also an antecedent of brand love.

Objectives: This study aimed to examine the effects of dietary protein intake and quality on periodontal disease in Korean adults. Methods: The data used for analysis were obtained from the 7th Korean National Health and Nutrition Examination Survey (2016-2018). Data were analyzed using chi-square and t-test. Additionally, multiple logistic regression analysis was performed to assess the association between dietary protein intake and quality and periodontal disease. Statistical significance level was set at <0.05. Results: Multiple logistic regression analysis of dietary protein intake and periodontal disease in the model adjusted for socioeconomic factors showed that were significantly related to the Q1 (odds ratio [OR]: 1.18, 95% confidence interval [CI]: 1.01-1.39). However, this correlation was not significant in the model in which all variables were corrected. Moreover, analysis of the dietary protein quality and periodontal disease in model 4, which was adjusted for socioeconomic variables, showed that were significantly related to the low score (OR: 1.13, 95% CI: 1.00-1.27). Conclusions: The results showed a significant association between periodontal disease and poor intake and quality of dietary protein in the Korean adult population.

본 논문에서는 미소진동 영향성 예측을 위한 인공위성 유한요소모델 보정에 관해 기술한다. 최근 지구 저궤도에 발사되는 상업용 지구관측위성의 경우, 수요자의 요구로 인해 주어진 시간 안에 다양한 지역의 많은 영상을 공급해야 한다. 이를 구현하기 위해 고용량휠, 다축 김발을 탑재한 안테나 등 다양한 구동기를 사용한다. 그러나 이러한 구동기는 작동 시 미소진동을 유발할 수 있으며, 이러한 미소진동은 매우 작기는 하지만 지구관측 탑재체를 가진하여 영상품질을 저감시킬 수 있다. 이러한 미소진동에 의한 영향성을 살펴보기 위해서 유한요소모델과 미소진동원 시험결과를 결합한 연성해석을 실시하며, 해석에 앞서 유한요소모델 보정을 실시한다. 보정 전후의 주파수 차이, 모드형상 상관관계, 주파수응답함수 상관관계를 비교하여 개선된 유한요소모델의 품질을 평가하였다.

Purpose: This paper is concerned with optimally designing accelerated degradation test (ADT) plans based on a gamma process for the degradation model. Methods: By minimizing the asymptotic variance of the MLE of the q-th quantile of the lifetime distribution at the use condition, the test stress levels and the proportion of test units allocated to each stress level are optimally determined. Results: The optimal plans of ADT are developed for various combination of parameters. In addition, a method for determining the sample size is developed, and sensitivity analysis procedures are illustrated with an example. Conclusion: It is important to optimally design ADT based on a gamma process under the condition that a degradation process should be always nonnegative and strictly increasing over time.

In order to evaluate the effectiveness of fuzzy reasoning to sensory tests, in this paper, a non-linear fuzzy system model that can estimate the general evaluator obtained from a numerical example of test of taste is constructed. And the applicability of fuzzy reasoning to sensory test is discussed on the basis of errors occurred from the estimates in combination of attributes of objects and from the results of multi-regression analysis. This paper proved that fuzzy reasoning using fuzzy If-then rules is applicable to sensory test.

In this paper, we consider the problem of testing independence in the absolutely continuous bivariate exponential distribution of Block and Basu(1974). We construct a bootstrap procedure for testing zero and non-zero values of the parameter ${\lambda}_3$ which measures the degree of dependence and compare the power of the bootstrap test with likelihood ratio test(LRT) by Gupta et al.(1984) and the test based on maximum likelihood estimator(MLE) $\hat{{\lambda}}_3$ by Hanagal and Kale(1991) for small and moderate sample sizes.

A military vehicle undergoes normal to extreme driving conditions, which consequently induce the fatigue and fracture of cabin and frame. So, it is important to estimate the fatigue life of two components at an initial design stage. In this paper, Modal Superposition Method(MSM) was applied to evaluate the durability performance of a small-sized military truck. For reliable durability analysis, a Virtual Test Lab(VTL) Model was established by correlation with experimental results. These data were extracted from actual driving test, modal test, and SPMD(Suspension Parameter Measuring Device) test. This process shows that Virtual Fatigue Analysis can be a useful approach in the development of military vehicles as well as commercial vehicles.
