This study examined the negative influence of ambiguity on the attitude toward ads by using mediating variable, perceived interpretation difficulty. It also tested the moderating effect of thinking style between ambiguity and perceived interpretation difficulty. In results, we found as follows. 1) Perceived interpretation difficulty is higher in case of higher ambiguity than lower one. 2) The influence of ambiguity on perceived interpretation difficulty is moderated by thinking style. 3) Attitude toward ads is more unfavorable in higher perceived interpretation difficulty than lower one. The results of this study may provide the implications that ambiguity ads using digital convergence media has to be connected to positive attitude for being successful and marketing staffs must consider thinking style as a key success factor to establish global advertising strategy.

The purpose of this study is to clearly recognize critical issues and to suggest relevant solutions for the issues since too many deaths and injuries due to industrial accidents has been going on for a long time, also the deaths of workers is a problem that affects not only one person's death but also many people connected with it and society as a whole. And the need for a strict Serious Accidents Punishment Act is sympathetic. However, the current Severe Accident Punishment Act is not welcomed by both labor and management due to its ambiguity, and it is suggested that the punishment and legislative content of the management manager who violated the duty to ensure safety and health is abstract and the level of punishment is excessive. In addition, due to the ambiguous part of the management manager's interpretation and serious industrial accidents, most companies appoint large law firms to receive legal interpretation and advice, so only law firms are getting full, and the cost that companies invest to protect the CEO is actually a safety accident. It is suggested that the current enforcement ordinance, which has ambiguity, needs to be revised because it must be entered into as a preventive cost.

초등학교 학급에서의 아동 상호간의 관계 파악은 아동 그룹이나 짝을 지어주고 교우관계를 분석하는데 매우 유용하다. 그러나 인간관계의 감정을 단순한 수치로 나타내기에는 아동 상호간의 복잡한 감정을 제대로 분석하기 힘들기 때문에, 본 논문에서는 퍼지 (Fuzzy) 이론을 기초로 하여 분석하고자 한다. 본 논문에서는 퍼지이론의 해밍거리(Hamming Distance)와 $\alpha$-수준집합을 적용하고 경향성을 계산할 수 있는 새로운 기법인 경향거리(Tendency Distance)를 제안하고 분석하는 기법을 연구하였다. 본 논문에서 제안하는 분석 방법의 특징은 첫째, 인간관계의 애매하고 모호한 점을 상대적 비교가 가능하게 함으로써 정확한 분석을 가능하게 하고, 둘째, 퍼지 이론의 적용을 통하여 해밍거리에 의한 유사도 분석에서 할 수 없었던 경향성의 분석을 가능하도록 하였으며, 셋째, 교육현장에서 발생할 수 있는 애매한 상황과 아동간의 교우 관계 등 수치적인 파악이 불가능한 부분을 분석이 가능한 데이터로 만들 수 있는 기법을 마련하였다는 데 의의를 둘 수 있다.

This paper presents a Fuzzy Pertri Net(FPN)model, which can be used to verify the validity and effectiveness of nervous system bebaviors. The similarities and differences between communication network and neural network are analyzed with respect to the representation and verification of the system behaviors. For the effective representation for the ambiguities of nervous system we combein fuzzy set theory to the PetriNet, and then design a new model, FPN, Also show that FPN is superior to the multiplayer perceptron model using computer simulation.

스트레오 영상 처리에 있어서 가장 중요한 단계는 좌우 영상간의 일치점을 찾는 영상 정합 단계라고 할 수 있다. 일반적인 영상 정합 방법으로는 영역 기반에 의한 방법과 특징점에 기반한 방법으로 나누어질 수 있다. 영역 기반의 방법은 많은 계산량을 필요로 하는 단점이 있으며, 특징점에 기반한 방법은 처리 속도는 향상시킬 수 있으나 전체적인 변이도를 구할 수 없는 단점이 있다. 한편 이미지 데이터 자체의 애매함이나 잡음, 처리 과정에서 발생하는 모호성, 인식과 해석 단계에서의 불확실한 지식등을 효과적으로 다루기 위해 퍼지 기법을 이용한 영상 처리 연구가 활발히 진행되고 있다. 본 논문에서는 각 픽셀의 밝기를 소속함수 값으로 변환한 후, 이 소속함수 값을 이용하여 좌우 영상의 일치점을 찾는 퍼지 스테레오 정합 알고리듬을 제안한다. 제안된 알고리듬은 몇 가지 스테레오 영상에 적용하여 그 유효성을 입증한다.

표현 기법, 특히 산업 디자인 전공에서 진행되고 있는 아이디어 스케치 단계 및 렌더링 테크닉에 있어서 흔히 광원(LIGHT SOURCE)의 개념에 대한 정확한 이해가 부족한 경우를 대하게 된다. 주로 제품 디자인이나 운송디자인에 있어서 마커와 파스텔을 사용하여 자신의 아이디어를 시각적으로 구체화시키게 되는데, 이 과정에서 면의 흐름이나 변화를 일관성 있는 가상적 광원의 설정에 따라 정리해나가지 않으면 결과적으로 대단히 애매하고 모호한 스케치나 렌더링이 될 수밖에 없다. 간결하고 정확한 디자인 프리젠테이션을 위해서는 시각적으로 쉽게 이해가 되는 표현기법을 디자이너가 적절하게 구사해야 하는 것이다. 그러면 본격적으로 제품과 자동차디자인 스케치 과정에서 적용되는 본인이 이론을 설명하기로 한다.

When measuring the value of environmental attributes of housing, the conventional Hedonic Pricing Method assumes market equilibrium. Thus each attribute is believed to be implicitly valued based on the market price. The revealed preference is the basic logic in this approach. However, if the participants in the housing market are not perfectly informed or feel vagueness regarding the attributes of the housing, the conventional Hedonic Pricing Approach could not provide relevant value of the attribute in question. A Fuzzy Regression Method is suggested to handle with the lack of information or preference uncertainty problem m the Hedonic Pricing Approach. In this paper, our main concern IS given to the fuzziness effect on the airport noise in the metropolitan areas of South Korea.

It is very difficult to quantize the ECG analysis because the decision criterion for ECG is different with each other depending on the medical specialists of the heart and there are measured detecting errors for each ECG measurement system. Therefore, we developed the real-time ECG identification system using digital fuzzy processor for STD-BUS, in order to reduce ambiguity generated in the process of ECG identification and to analyze the irregular ECG stastically to ECG's repetition interval. The variables such as AGE (months), width of QRS, average RRI, and RRI were used to classify the ECG, and were applied to ECG signal indentification system which is developed for the purpose of research. It was found that the automatic diagnosis of ECG signal was possible in the real time process which was impossible in general process of algorithm.

본 논문은 crisp discrete event system(CDES)에서 다룰 수 없는 특성을 가지는 의료진단이나 교통제어와 같이 애매하거나 불확실한 판단 그리고 관련성이 모호한 판단의 근거들에 의해 결정되어지는 사건들로 이루어진 fuzzy discrete event system(FDES)의 모델링 방법에 대하여 연구하였다. CDES는 모델링 방법이 많이 연구되어져 왔으나, FDES는 발생되어지는 사건들의 정성적인 특성과 적용되어지는 경우가 드문 이유로 거의 연구되어져 있지 않다. 본 논문에서는 temporal logic에 fuzzy개념을 도입하여 fuzzy DES의 새로운 모델링 방법을 제시하고 의료진단 시스템에 적용하였다.

Modern optical mechanisms slanted toward Ocular-centrism have neglected diverse functions of vision, judged objects in abstract and binary perspectives, and organized spaces accordingly, there by neglecting the function of eyes groping objects. Recently, various experiences have been induced through communication with other senses by the complex perception beyond the binary perception system of vision. Haptic perception is dynamic vision that induces accompanying bodily experiences through interaction among the various senses; it recognizes the characteristics of material properties and various sensitive stimulations of human beings. This study elaborates on the major features of haptic perception by examining the theoretical background of this concept, which stimulates the active experience of the subject and determines how characteristics of haptic perception are displayed in picturesque gardens. In order to identify the major features of haptic perception, this study examines how Adolf Hildebrand's theory of vision is developed, expanded, and reinterpreted by Alois Riegl, Wilhelm Worringer, Walter Benjamin, Maurice Merleau Ponty, and Gilles Deleuze in the histories of philosophy and aesthetics. Based thereon, the core differences in haptic perception models and visual perception models are analyzed, and the features of haptic perception are identified. Then, classical gardens are set for visual perception and picturesque gardens are set for haptic perception so that the features from haptic perception identified previously are projected onto the picturesque gardens. The research results drawn from this study regarding features of haptic perception presented in picturesque gardens are as follows. The core differences of haptic perception in contrast to visual perception can be summarized as ambiguity and obscureness of boundaries, generation of dynamic perspectives, induction of motility by indefinite circulation, and strangeness and sublime beauty by the impossibility of perception. In picturesque gardens, the ambiguity and obscureness of boundaries are presented in the irregularity and asymmetric elements of planes and the rejection of a single view, and the generation of dynamic perspectives results from the adoption of narrative structure and overlapping of spaces through the creation of complete views, medium range views, and distant views, which the existing gardens lack. Thus, the scene composition technique is reproduced. The induction of motility by indefinite circulation is created by branching circulation, and strangeness and sublime beauty are presented through the use of various elements and the adoption of 'roughness', 'irregularity', and 'ruins' in the gardens.
