  • In this study, the RDA DMP Common Standard (RDCS), a data model for implementing a machine actionable Data Management Plan (maDMP), was analyzed in four aspects. First, the twelve class models proposed by RDCS were analyzed. Second, whether the DMP attribute was included in the class attribute was analyzed. Third, we analyzed the namespace used for RDCS properties. Fourth, the values and identifiers used in RDCS properties were analyzed. As a result of the analysis, four directions for improvement were derived. First, it is necessary to add an academic record class to describe information such as papers and reports, which are representative academic documents. Second, the primary research institution, responsibility, resources, option attribute, and additional attributes are needed to describe the researcher's affiliation information. Third, it is necessary to additionally use a namespace such as Friend of a Friend that can be used universally. Fourth, the use of digital object identifier should be considered to identify academic literature.

  • 본 논문은 대규모 데이터베이스에서 유용한 지식을 발견하기 위해 라프셋을 중심으로 한 통합적 방법을 제시한다. 본 방업에서는 데이터베이스에 있는 실제 데이터에서 일반화된 데이터를 추출하기 위해 속성중심의 개념계층 상승기법을 사용하고, 획득 정보량을 측정하기 위해 결정 트리에 의한 귀납법을 사용한다. 그리고 불필요한 속성 및 속성값을 제거하기 위해 라프셋 이론의 지식감축 방법을 적용한다. 통합 알고리즘은 먼저, 개념의 일반화에 의해 데이터베이스의 크기를 줄이고, 다음으로 결정속성에 영향을 적게 미치는 조건속성을 제거함으로써 속성의 수를 줄인다. 마지막으로 속성간의 종속관계를 분석함으로써 불필요한 속성값을 제거하여 간략화된 결정규칙을 유도한다.

  • This paper describes a new process-plan selection method using a modified Fuzzy Quantification Theory(FQT). The problem for process-plan selection can be characterized by multiple attributes and used subjective, uncertain information. Fuzzy Quantification Theory is used for handling such informations because it is a useful tool when human judgment or evaluation is quantified via linguistic variables and the proposed method is concerned with the selection of a process plan by derivation of the values of categories for each attribute. In this paper, a modified Fuzzy Quantification Theory(FQT) is described and the procedure of this approach is explained and examples are illustrated.

  • Purpose: This research investigates ready-to-drink (RTD) coffee. Although the RTD coffee market is growing competitively, few studies have examined behavioral re-intention or repurchase intention in the context of this industry. Therefore, the objective of this study was to explore factors affecting the behavioral re-intention to purchase RTD coffee. Research design, data and methodology: Using the theory of planned behavior (TPB) as the underpinning theoretical framework, this study hypothesized that behavioral re-intention to purchase RTD coffee is influenced by the variables of the TPB and additional variables. A mixed-method research design was applied, starting with qualitative in-depth interviews and followed by a quantitative method. Data were collected using an online survey of coffee lovers. Multiple linear regression (MLR) was used to assess the hypothesized relationships in the proposed conceptual framework. Results: The results reveal that content sensory attribute beliefs are the strongest positive predictor of behavioral re-intention in Thailand, followed by perceived utilitarian value. In contrast, price signaling was negatively related to behavioral re-intention. Conclusions: The findings can help food and beverage companies to develop new coffee product lines to gain more market share, create integrated marketing communications to build brand awareness, and manage distribution channels and the supply chain.

  • Every public agency governing infrastructure has to plan effectively for rehabilitation of existing facilities within the constraints of the capital program. Numerous technical, social, political, financial, and management constraints govern the decision to rehabilitate a facility. However, without a systematic procedure for selecting facilities for rehabilitation, within the prevailing constraints, it is possible that the funds available for rehabilitation might be suboptimized. Therefore, a decision support system that assists the user in selecting facilities for rehabilitation while considering the technical, social, financial, and political and management constraints will be useful in the decision-making process. This paper compares the Analytical Hierarchy Process (AHP) with the Swing Weight method used to prioritize functional criteria for suburban station rehabilitation. This paper also contains a brief discussion about the relevance of the Multi Attribute utility theory in developing a decision model for the problem at hand. The results of this paper provides the user with a decision support system that would prioritize the stations in order of their weights obtained by a systematic evaluation of various criteria and sub-criteria involved in the decision making process

  • 본 논문에서는 상거래에 참여한 구매자와 판매자가 협상을 통하여 서로의 이익을 보장하면서 합의를 도출 할 수 있는 협상 에이전트 시스템을 제안하였다. 제안 시스템은 기존의 협상 에이전트 시스템에 기계 학습을 적용함으로써, 학습 에이전트의 도입이 협상의 효율성에 어떤 영향을 미치는지 고찰하고자 하였다. 구매자 및 판매자 에이전트는 상품의 다중 속성을 고려하여 협상을 수행하며, 구매자와 판매자의 이익은 Multi-Attribute Utility Theory를 이용하여 표현하였다. 본 연구에서 제시된 학습 가능한 협상 에이전트는 Faratin이 제안한 협상 시스템의 제안 생성(counter offer) 과정에 인공신경망을 통한 점진적 학습 기업을 추가함으로써 협상의 효율성을 증가시키는데 목적이 있다. 점진적 학습기법을 이용한 협상 에이전트 시스템의 경우, 동일한 협상 조건 하에서 상대방 제안과의 유사도(similarity)를 바탕으로 제안을 생성하는 기존의 다른 협상 에이전트 시스템과 비교하였을 때 좋은 협상 결과를 보여 주었으며, 협상 수행시간에 있어서는 매우 빠른 성능을 보여주었다. 따라서 협상 결과 및 협상 수행 시간을 동시에 고려하였을 때 기존의 협상 시스템에 비하여 효율적인 협상 능력을 보여 주었다.

서비스 속성과 고객만족과의 비대칭적, 비선형적 관계에 근거한 서비스 속성 분류와 전략적 고객서비스 경영 (Classification of Service Attributes and Strategic Customer Service Management based on the Asymmetric and Non-linear Relationship between Service Attributes and Customer Satisfaction)

  • The principal objective of this study was to categorize service attributes on the basis of the asymmetric and non-linear relationship existing between service attributes and customer satisfaction. Researchers generally assume that service attribute performances and customer satisfaction are both symmetrical and linear. That is to say, improvements in attribute performance will inevitably result in increased customer satisfaction. However, this is not always the case. Certain attributes have been shown not to create satisfaction even when improved, and others do not create dissatisfaction even when their performance ratings become negative. Understanding this relationship is crucial not only to researchers, but also to service managers. Service managers can arrange their priorities with regard to which attributes must be improved or promoted first, in an environment of limited technical, financial, and human resources. Many studies into this asymmetric and non-linear relationship have recently been conducted, beginning with Herzberg's motivation-hygiene theory (1976) and the disconfirmation theory, which was eventually developed into Kano's model (1984). This study attempted to determine the impact level of service attributes on incidents of satisfaction or dissatisfaction. It used 30 service attributes generated by Park (2008) in the CIT research into family restaurants. The data were collected from 600 participants, 300 incidences of satisfaction and 300 incidents of dissatisfaction, via an online survey. The t-test was used to confirm the difference between the satisfaction group's and dissatisfaction group's attributes. 11 attributes were found to be significant at a level of p>0.05. This indicates that the 11 attributes exerted different impacts on satisfaction and dissatisfaction, which confirmed the asymmetric and non-linear relationship. 14 attributes were categorized into the core service, 1 attribute into the quality service, 7 attributes into the basic service, and 8 attributes into the neutral service. Strategic customer service management was recommended for the 'A' family restaurant as an example, on the basis of the asymmetric and non-linear relationship and the characteristics of the four service factors.
