In the Quality Control and inspection processes, the use of attribute sampling strategies is crucial. In this study, we incorporate the neutrosophic fuzzy acceptance sampling plan method to present a fresh approach to attribute sampling plans. Utilizing the benefits of neutrosophic fuzzy sets, the proposed sampling plan method models and assesses the acceptance standards for attribute sampling. We compare the suggested method to already-in-use attribute sampling techniques plans with new attribute six sigma sampling techniques plan is proposed in order to verified its efficacy. The outcomes show the neutrosophic fuzzy acceptance sampling plan's superiority in terms of its capacity to manage uncertainties, account for ambiguity, and produce more precise quality evaluation outputs.

Some laws and regulations may require internet service providers to provide services based on the age of users. Age verification in the online environment should be used as a tool to provide service that is appropriate to child based on age. Using the minimum attribute information, processes on age verification provides the proper guidance to the internet services. However, there is a lack of a globally accepted trust framework for age verification process including evaluation factors for age verification information. In this paper the federation model of user attributes were described and evaluation factors for the age verification information were suggested. Also using the suggested evaluation factors, performance evaluation of federation model of user evaluation was performed. To meet the requirements of evaluation factors, framework of federation model should consider the unlinkability pseudonym support, eavesdropping protection and cloning protection.

복잡한 언어 처리에 점진적 속성 문법을 적용하기 위해서는 최적화 알고리즘을 사용하는 것이 효과적이다. 점진적 속성문법의 최적화 알고리즘에서는 새로운 입력 속성 트리가 기존 입력 속성 트리와 정확히 비교되어서 새로운 속성 트리를 구성할 대 기존 속성 트리의 어떤 서브트리를 사용해야 하는가를 결정한다. 본 논문에서는 Carle과 Pollock에 의해 제안된 알고리즘을 분석하여 효과적인 최적화 알고리즘으로 재구성하고, 새로은 속성 트리 d'copy의 생성 과정과, 속성트리 d'copy의 새로운 최적화 알고리즘을 추가하였다. 이 논문에서 제안한 매칭 알고리즘의 성능평가를 통하여 기존의 알고리즘 보다 제안한 최적화 알고리즘의 실행 시간을 약 19.5% 향상 시킬 수 있었다.

구조실험을 위한 데이터 모델은 구조실험에 관련된 실험정보를 정형화하여 표현하므로 데이터 저장소를 개발하는데 이용할 수 있다. 데이터 모델은 특히 대규모의 구조실험정보 또는 일반적인 다양한 실험정보를 위한 데이터 저장소에 효과적인데 예를 들면 NEES에서 개발한 NEEShub Project Warehouse가 있다. 본 논문은 데이터 모델의 구성과 사용을 평가하기 위한 평가요소를 제안하고 있다. 클래스의 속성이 값을 갖는지를 의미하는 AVE(attribute value existence)란 용어를 도입하여 속성의 사용성에 대한 Attribute AVE, 클래스의 사용성에 대한 Class AVE, 하위레벨에 있는 클래스를 포함하는 Class Level AVE, 하나의 프로젝트의 모든 클래스를 포함하는 Project AVE, 모든 프로젝트를 포함하는 데이터 모델에 대한 Data Model AVE를 정의하였다. 이러한 평가요소들을 NEES 데이터 모델의 프로젝트들에 적용하였는데 데이터 모델내의 클래스와 객체에 대한 사용성을 수치적으로 기술하여 평가하는 것이 가능하였다.

데이터 스트림은 빠르게 연속적으로 발생하는 무제한의 데이터 튜플의 집합이다. 이러한 데이터 스트림에 대한 질의 처리 또한 연속적이고 신속해야 하며 엄격한 시공간적 제약이 요구된다. 대부분의 데이터 스트림 관리시스템(DSMS)에서는 시공간적 제약사항을 효과적으로 지키기 위해서 등록된 연속 질의들의 선택 조건(selection predicate)들을 그룹화하거나 색인처리 한다. 본 논문에서는 연속 질의들의 선택 조건들을 속성별로 그룹화한 새로운 구조체인 속성 선택체(Attribute Selection Construct)를 제안한다. 속성 선택체에는 해당 속성이 특정 질의조건에 사용되는지 여부, 부분적으로 미리 계산된 질의결과 정보, 그리고 해당 속성의 선택률 통계 등 효율적인 질의 처리를 위한 유용한 정보들이 포함된다. 또한, 대상 질의집합을 구현한 속성 선택체들 간의 처리 순서는 전체적인 질의성능에 많은 영향을 미칠 수 있기 때문에 효과적으로 속성 선택체 처리 순서를 결정할 수 있는 전략도 함께 제안된다. 마지막으로, 기존의 방법들이 포함된 다양한 실험을 통하여 제안된 방법론의 성능을 여러 각도에서 비교 검증한다.

This study investigated the difference in the influence of shopping orientations, attributes evaluation, and benefits sought on brand loyalty between Korean and American consumers within a clothing purchase context. Questionnaires were administered to 237 Korean consumers and 184 American college students who had purchase experience of casual wear in recent six months through off-line. The results were as follows. First, the hedonic shopping orientation had a positive impact on brand loyalty in both groups, whereas efficient shopping orientation had a positive impact on brand loyalty in American group. Second, the aesthetic attribute had a positive impact on brand loyalty in both groups, whereas utilitarian attribute had a positive impact on brand loyalty in Korean group. Third, brand value benefit sought had a positive impact on brand loyalty in Korean group and body expression/complement had a positive impact on brand loyalty and economic benefit sought had a negative impact on brand loyalty in American group.

쌀밥의 관능검사 결과분석에 퍼지추론을 적용하였다. 관능검사시 쌀밥의 관능적 요인인 조직감, 맛, 냄새 및 외관이 각각 쌀밥 기호도의 결정에 역할하는 정도(기여도)를 매우중요, 요, 보통, 경시, 매우경시의 택일으로서 평가하도록 하였으며, 주어진 쌀밥 시료에 대하여 각관능척 요인의 기호도를 매우우량, 우량, 보동, 불량, 매우불량의 택일로서 평가하도록 하였다. 퍼지추론 과정으로 먼저 전체기호도에 대한 일반적인 관능적 요인의기여도를 추론하고, 시료에 대한 관능적 요인의 기호도틀 추론된 기여도와 퍼지합성하여 결과적으로 전체기호도를 추론하였다.

The purpose of this study were to investigate the relationships between consumer's value and sportswear's benefit sought/attribute evaluation, and to examine how sportswear's benefit sought were influenced by consumers' value and demographic variables. Subjects were 468 males and females in their teens to 30's in Seoul. Consumer's value was classified into four dimensions by using factors analysis: materialism, achievement orientation, traditionalism, and other consciousness. The value of materialism and achievement orientation had positive relations with brand orientation, fashion, appearance attraction, enterprise image, and brand advertisement of sportswear in both male and female. Achievement orientation had, in case of the male, positive relations with economics, practicality, fabrics, and quality of sportswear. In case of the female, traditionalism had positive relations with economics and practicality, and other consciousness value had positive relations with brand advertisement. Materialism was the most important in predicting brand orientation, followed by social class in both male and female. Age was the most important in predicting practicality, followed by achievement orientation in case of the male. Materialism(-) was, in case of the female, the most important in predicting practicality, followed by traditionalism, achievement orientation, and age.

The purpose of this study was to investigate the demographics and general clothing buying behavior according to clothing shopping orientation of female workers. A questionnaire was developed to measure clothing shopping orientation, fashion information sources, stores selection criteria, clothing purchasing frequency of a year, purchasing expenditure of clothing, the demographics. The questionnaire was administered to 775 female teacher in Chonnam. The data was analyzed using percentage, frequency, mean, factor analysis, Cluster Analysis, x 1_test and ANOVA, Duncan test. The results of the study were as follows: 1. The female teachers were classified into four groups by the cluster analysis; indifferent shopping group, rational shopping group, conspicuous shopping group, recreational shopping group. 2. In the case of purchasing motives, significant differences were found according to shopping orientation subdivision in four factors. 3. The evaluation criteria of product were significantly different depending on shopping orientation subdivision in practical attribute, socio-psychological attribute, and aesthetic attribute. 4. The significant differences were found according to shopping orientation subdivision in general clothing purchasing behavior(purchasing price range of clothing, clothing purchasing frequency of a year, method of payment, number of stores visited, experience of buying in the import brand)

This study investigated consumer preferences for Internet medical information service in China using the multi-attribute utility theory. The multi-attribute utility theory is a compositional approach for modeling consumer preferences wherein researchers calculate the overall service utility by summing up the evaluation results for each attribute. We found that Chinese Internet medical information users consider the availability of information and quick response to be the most important attributes. Further, they think that the comment feature is less important as compared to other attributes such as costs and updates. In addition, we found that the Internet users having more Internet experience consider these attributes to be more important as compared to the people who are just beginning to surf the Internet. For any successful Internet business, Internet marketers should assess individual-level preference and accordingly organize a fresh campaign. As of now, Internet marketers need estimation methods to predict the market performance of new services in many different business environments. We believe that the multi-attribute utility theory is a useful approach in this regard.
