This paper sets forth the phenomenon of Contrastive Reduplication (CR) in English relevant to the notion of contrastive focus (CF). CF differs from other reduplicative patterns in that rather than the general intensive function, denotation of a more prototypical and default meaning of a lexical item appears from the reduplicated form resulting as a semantic contrast with the meaning of the non-reduplicated word. Thus, CR is in concordance with CF under the concept of contrastivity. However, much of the previous works on CF associated contrastivity with a manufacture of a set of alternatives taking a semantic approach. We claim that a recent discourse-pragmatic account takes advantage of explaining the vague contrast in informativeness of CR. Zimmermann's (2006) Contrastive Focus Hypothesis characterizes contrastivity in the sense of speaker's assumptions about the hearer's expectation of the focused element. This approach makes possible adaptation to CR and recovers the possible subsets of meaning of a reduplicated form in a more refined way showing contrastivity in informativeness. Additionally, CR in other languages along with similar set-limiting phenomenon in various languages will be introduced in general.

In this paper, we propose a method to automatically generate the description of an RDF graph structure. The description is expressed in Shape Expression Language (ShEx), which is developed by W3C and provides the syntax for describing the structure of RDF data. The RDF graphs to which this method can be applied are limited to those generated by the direct mapping, which is an algorithm for transforming relational data into RDF by W3C. A relational database consists of its schema including integrity constraints and its instance data. While the instance data can have been published in RDF by some standard methods such as the direct mapping, the translation of the schema has been missing so far. Unlike the users on relational databases, the ones on RDF datasets were forced to write repeated vague SPARQL queries over the datasets to acquire the exact results. This is because the schema for RDF data has not been provided to the users. The ShEx documents generated by our method can be referred as the schema on writing SPARQL queries. They also can validate data on RDF graph update operations with ShEx validators. In other words, they can work as the integrity constraints in relational databases.

사업 초기 단계에서의 정확한 공사비 예측은 각각의 대안을 비교하여 향후 공사비에 대한 정보를 제공함으로써 효율적인 예산수립을 가능하게 한다. 하지만 사업 초기 단계에는 공사비 산정 기준이 모호하고 가용 정보가 부족함에 따라 공사비 예측에 한계가 나타난다. 더욱이 현행 공사비 산정모델이 단위 길이당 공사비를 활용한 선형적이고 단순한 모델을 활용함에 따라 예측의 정확도에 한계를 가지고 있다. 따라서 본 연구에서는 기존 공사비 산정모델의 한계를 개선하고 사업 초기 단계에서 가용한 데이터를 활용할 수 있는 공사비 산정 모델의 Framework를 구축하고자 한다. 이를 위하여 본 연구에서는 국내외 개략공사비 산정 모델을 분석하였으며, 기존 도로공사의 공사비 분석자료를 토대로 노선선정 등 사업초기 단계에서 활용 가능한 도로공사 개략공사비 산정모델의 Framework를 제시하였다.

의료정보 기술의 Smart 환경, Ad-hoc networking, 무선통신 환경은 u-Healthcare 요소기술과 함께 정보보안 취약성을 증가시키는 주요 요인이다. 트래픽 도메인이란 u-Healthcare 의료정보시스템을 통과하는 트래픽 구간의 구분 영역으로서 보안기술의 적용이 가능하도록 네트워크 영역을 구분하는 개념이다. 그 구분의 기준은 보안기술의 적용이 필요한 영역, 트래픽 경로와 트래픽 성격이 타 도메인과 차별화 가능한 영역, 보안기술 적용시 타 영역의 보안기능으로 기능중복이 발생치 않는 영역이다. u-Healthcare 의료정보시스템 도메인은 사용자단말구간, 공중통신망 인프라구간, 네트워킹구간, 인트라넷구간으로 도출된다. 의료정보시스템을 도메인별로 구분하여 취약점을 평가하는 이유는 도메인별로 취약점에 대한 대처방법이 다르게 도출되기 때문이다. 본 연구는 의료정보시스템 도메인을 도출하고 도메인별 보안취약성 진단체계를 설계하여 USN 기반 u-Healthcare 시스템에서의 보안대책을 강구하기 위해서이다. 본 연구에서 제안하는 모델을 사용할 경우 현재까지 막연하게 진행 되어온 USN 기반 의료정보네트워크 보안취약성 진단대책 수립 방법을 좀 더 효과적으로 수행 할 수 있을 것으로 기대한다.

Quality function deployment (QFD) is a widely adopted customer-oriented product development methodology by translating customer requirements (CRs) into technical attributes (TAs), and subsequently into parts characteristics, process plans, and manufacturing operations. A main activity in QFD planning process is the determination of the target levels of TAs of a product so as to achieve a high level of customer satisfaction using the data or information included in the houses of quality (HoQ). Gathering the information or data for a HoQ may involve various inputs in the form of linguistic data which are inherently vague, or human perception, judgement and evaluation for the information and data. This research focuses on how to deal with this kind of impreciseness in QFD optimization. In this paper, it is assumed as more realistic situation that the values of TAs are taken as discrete, which means each TA has a few alternatives, as well as the customer satisfaction level acquired by each alternative of TAs and related cost are determined based on subjective or imprecise information and/or data. To handle these imprecise information and/or data, an approach using some basic definitions of fuzzy sets and the signed distance method for ranking fuzzy numbers is proposed. An example of a washing machine under two-segment market is provided for illustrating the proposed approach, and in this example, the difference between the optimal solution from the fuzzy model and that from the crisp model is compared as well as the advantage of using the fuzzy model is drawn.

The purpose of this study is to provide a decision support to select an appropriate rapid prototyping(RP) machine that suits the application of a part. Selection factors include concept model, form/fit/functional model, pattern model for molding, material property, build time and part cost that greatly affect the performance of RP machines. However, the selection of a RP is not an easy decision because they are uncertain and vague. For this reason, the aim of this research is to propose hybrid multiple attribute decision making approaches to effectively evaluate RP machines. In addition, because subjective considerations are relevant to selection decision, a fuzzy logic approach is adopted. The proposed selection procedure consists of several steps. First, we identify RP machines that the users consider. After constructing the evaluation criteria, we calculate the weights of the criteria by applying the fuzzy Analytic Hierarchy Process(AHP) method. Finally, we construct the fuzzy Technique of Order Preference by Similarity to Ideal Solution(TOPSIS) method to achieve the ranking order of all machines providing the decision information for the selection of RP machines.

Purpose - Although marketing networks are crucial competitive advantage in terms of firm's new information and resource acquisition ability, their impact on new product development performance remains vague, especially under environmental uncertainty. The principal objective of this research is to provide a better understanding of effects of technological uncertainty and volume uncertainty on first tier supplier's perceived performance of new product development under conditions reflecting varying levels of structural holes. Specifically, this research examines the moderating effect of structural holes on the relationship between environmental uncertainty and new product development performance. Research design, data, and methodology - To test the hypotheses, a questionnaire survey was conducted with a Korean engineering firm's major first-tier suppliers in the context of internal network entities, manufacturer-supplier-subsupplier relationships, and to verify the proposed hypotheses, structural equation modeling was established. Construct measures were based on existing measures and previous research. Results - The survey results indicate that technological uncertainty and volume uncertainty differentially affect NPD performance under conditions of high and low structural holes. Conclusions - This study offer some theoretical and practical implications among distribution channel members, especially, this study suggests that interfirm networks have critical competitive advantage in uncertain environments. The distinctiveness of engineering industry might limit the generalizability of the results. Thus, future research should consider a wider range of industries.

This paper deals with modeling method and application of Fuzzy Discrete Event System(FDES). FDES have characteristics which Crisp Discrete Event System(CDES) can't deals with and is constituted with the events that is determined by vague and uncertain judgement like biomedical or traffic control. We proposed Real-time Fuzzy Temporal Logic Framework(RFTLF) to model Fuzzy Discrete Event System. It combines Temporal Logic Framework with Fuzzy Theory. We represented the model of traffic signal systems for intersection to have the property of Fuzzy Discrete Event System with Real-time Fuzzy Temporal Logic Framework and designed a traffic signal controller for smooth traffic flow. Moreover, we proposed the method to find the minimum-time route to reach the desired destination with information obtained in each intersection. In order to evaluate the performance of Real-time Fuzzy Temporal Logic Framework model proposed in this paper, we simulated unit-time extension traffic signal controller model of the latest signal control method on the same condition.
