This paper presents a feasibility study on structural damage alarming and localization of long-span cable-supported bridges using multi-novelty indices formulated by monitoring-derived modal parameters. The proposed method which requires neither structural model nor damage model is applicable to structures of arbitrary complexity. With the intention to enhance the tolerance to measurement noise/uncertainty and the sensitivity to structural damage, an improved novelty index is formulated in terms of auto-associative neural networks (ANNs) where the output vector is designated to differ from the input vector while the training of the ANNs needs only the measured modal properties of the intact structure under in-service conditions. After validating the enhanced capability of the improved novelty index for structural damage alarming over the commonly configured novelty index, the performance of the improved novelty index for damage occurrence detection of large-scale bridges is examined through numerical simulation studies of the suspension Tsing Ma Bridge (TMB) and the cable-stayed Ting Kau Bridge (TKB) incurred with different types of structural damage. Then the improved novelty index is extended to formulate multi-novelty indices in terms of the measured modal frequencies and incomplete modeshape components for damage region identification. The capability of the formulated multi-novelty indices for damage region identification is also examined through numerical simulations of the TMB and TKB.

The purpose of this study is to evaluate Aldo Rossi's work as representation or non-representation, for some hold that the works of Aldo Rossi are representative and others say that they are non-representative. According to the three kinds of novelties appearing after Stephen Pepper's concept, "the breaking of reference" happens, and Aldo Rossi's concept, "the sense of deposition" Rossi's work is uncovered as non-representation. In order to clarify Rossi's work as non-representation, we are going to borrow Pepper's terms, intrusive novelty, emergent novelty, and naive novelty. The breaking of reference accompanies intrusive novelty to bring a sense of representation, emergent novelty to intuit a sense of non-representation, and naive novelty to a sense of newness of disorder. We hope to verify a hypothesis that Aldo Rossi's architectural thought and the architecture come from 'emergent novelty' on the basis of his two books, A Scientific Autobiography and Architecture of the City. Also this paper discusses qualitative aspects rather than visual aspects. The main concepts of emergent novelty are applied to Aldo Rossi's works and his thought. Finally this paper verifies 'the hypothesis' through revealing what Aldo Rossi means by the quality of suspension, the sense of deposition, and idea of the unfinished(repetition). Rossi's work is not textural reference of representation appearing after blocking, but qualitative reference of non-representation.

A travel destination offers a form of novelty to the traveler since it can provide experiences that are not of the everyday variety. Therefore, a search for novelty is important as a motivation factor when planning leisure trips and vacation activities and to identify travel market segments. This study aimed to examine the differences in demographic characteristics, travel style, and preferred food-related activities in accordance with the level of tourists' novelty seeking. This study investigated potential tourists using a self-administered questionnaire survey, which resulted in 300 usable questionnaires. The respondents of this study were classified into two groups according to their level of novelty seeking: Active novelty-seeking group and Passive novelty-seeking group. These two groups were significantly different with respect to demographic characteristics, travel style, and preference of food-related-activity experience. The results show that the Active novelty-seeking group tended to have a higher proportion of females and specialized jobs, a higher level of monthly income and education, more frequent travel, and preference for food-related activity experience than other groups. The result of this study will be helpful for the tourist industry, which needs to develop culinary and food-related experience tour programs and travel market segments.

본 연구에서는 기존의 전형성에서 긍정/부정이라는 정서적 방향성이 분명하게 이탈된 디자인을 활용한 제품에 대한 선호도와 구매의사에 성격이 어떤 영향을 미치는지를 알아보았다. 기존의 긍정적 전형성에서 부정적으로 이탈된 디자인 제품과 기존의 부정적 전형성에서 긍정적으로 이탈된 디자인 제품에 대한 참가자들의 선호도와 구매의사가 측정되었으며 여기에 미치는 개인 특성으로 외향성, 신경증, 심미적 성향이 측정되었다. 연구 결과, 참가자들은 부정적으로 이탈된 디자인 제품보다 긍정적으로 이탈된 디자인 제품을 훨씬 더 선호하였고 구매의사도 더 높았다. 부정적으로 이탈된 디자인 제품의 선호도에는 신경증이 유의미한 영향을 미쳐 신경증이 높을수록 부정이탈 디자인 제품을 더 선호하였다. 또한 부정이탈 디자인 제품의 구매의사에 대해서는 선호도와 외향성의 상호작용 효과가 나타났는데, 즉 내향적인 사람일수록 높은 선호도가 실제 구매의사로 이어질 가능성이 유의미하게 높았다. 반면 긍정이탈 디자인 제품에 대해서는 성격의 효과가 전혀 나타나지 않았다. 본 연구의 결과는 부정적인 정서를 유발하는 전형성 이탈 디자인 제품에 있어서는 개인의 성격적 특성이 선호도 및 구매의사에 중요한 역할을 함을 보여준다.

본 연구의 목적은 크게 3가지로 요약할 수 있다. 첫째, 한국을 방문한 미국, 일본, 중국관광객들 사이에 한국에서의 신기성 경험, 심리적 거리, 만족도에 대한 차이가 존재하는지 조사하기 위한 것이다. 둘째, 신기성 경험이 관광객들의 관광경험 만족도에 어떠한 영향을 미치는지 조사하기 위해서이다. 셋째, 관광객들이 한국에 대해 인식하는 심리적 거리가 신기성 경험에 어떠한 영향을 미치는지 이해하기 위해서 이다. 이러한 연구목적들을 달성하기 위해 한국방문을 마치고 떠나는 미국, 일본, 중국관광객들을 대상으로 인천공항 출국장에서 설문조사를 실시하였고, 최종적으로 307개의 유효한 설문지를 회수하였다. 실증 분석결과에 따르면, 관광객들이 인식하는 한국에 대한 심리적 거리, 신기성 경험정도, 만족도는 국적별로 유의한 차이가 있는 것으로 나타났다. 덧붙여, 관광객이 인식하는 심리적 거리는 신기성 경험에 영향을 미치는 것으로 나타났으며, 신기성 경험은 관광객의 만족도에 긍정적인 영향을 미치는 것으로 나타났다. 이 연구의 결과는 재정립된 신기성 개념을 통하여 관광객 행동을 이해하는데 기여하고 있다.

Urban regeneration, which implies a certain type of change from what has previously existed, requires fundamental understandings of previous problematic ways of thinking for a meaningful change, as well as a new philosophy that is thought to support that change. This means a change in philosophy is needed to discuss 'newness' in urban regeneration. From this perspective, this paper explores the philosophies which shaped traditional cities as well as a philosophy that may be able to suggest changes to contemporary cities. This paper further proposes contextual novelty as necessary to pursue. This contextual novelty does not deny modern cities' problems but embraces them and carries them into contemporary cities. Arguing for qualitative novelty, this paper argues that contextualism, which explores the complex relationships of direct and indirect contributors of a given event, can help us to understand contemporary cities' heterogenic characteristics. In this context, this paper discusses the concept of novelty in contemporary discourse of urban regeneration by using the philosophy of contextualism. Finally a recent example of urban regeneration in the city of Gwangju, South Korea is interpreted using the concept of contextual novelty.

Travel motivations appear particularly useful in describing those individuals who visit a specific travel attraction versus those who do not visit the attraction. Novelty seeking is an important motivator for traveling today. In this study four factors and three groups resulting from a cluster analysis were tested in determination for 13 preference and 21 motivators. The major finding of this study are as follows: Prior consideration in oversea travel for people is to expect to contact new culture and exotic environment. In the selection of oversea travel with the level of novelty seeking traits, rhere is meaningfull diffrences. In the novelty seeking levels of leisure activities remarkable difference appeared in the selective degree variables and the examination of the gap. In the selection of oversea with the novelty seeking level it displayed meaningful differences in the 10 items. In a travel in accordance with levels of novelty seeking- which is divided into groups high, medial, and, low level of novelty seeking groups- four elements of their levels demonstrated meaningful differences, such as adventure seeking type, out-of-ordinary life type, fun seeking type and free travel type. In order words, the means of high-concerned group, medial, and ldw-concerned group showed remarkable differemndes.

This study attempted to determine the influence of organizational structure on the novelty preference for corporate meeting destination choice. The three dimensions of structure incorporated were formalization, centralization and complexity. A total of 75 corporate meeting planners drawn from public listed services organizations were involved. The main method of data collection was questionnaire survey and multiple regression analysis was employed as the main statistical technique. The results revealed that both formalization and centralization were negatively correlated with novelty preference while complexity was positively correlated. However, only complexity contributed significantly to the prediction of novelty preference for corporate meeting destination choice. The main implication of this study is pertaining to the segmentation and targeting of the corporate meeting market. This study helped in bridging the gap between tourism marketing and organizational research. It also contributed by developing the measurement for novelty preference from the context of experiential marketing.

웹 상에 수 많은 문서가 등장함에 따라 기존 문서와 내용이 중복되는 문서를 찾아서 제외함으로써 새로운 문서를 찾는 노력을 줄일 수 있어 문서 수준의 신규성 탐지(novelty detection)가 중요해졌다. 최근 연구에서는 합성곱 신경망(CNN) 구조 기반의 신규성 탐지 모델 구조가 제안되었고 상당한 성능 향상을 나타내였다. 본 논문에서는 기존의 CNN 기반의 모델에서 문서 수준의 정보가 제한적으로 사용되는 것을 관측하고 문서의 신규성을 결정할 때 문서 수준의 정보가 중요하므로 제한적인 사용이 문제가 된다고 가정하였다. 이에 대한 해결책으로, 본 논문에서는 합성곱 신경망 기반 신규성 탐지 모델 구조를 개선하여 문서 수준 정보를 효과적으로 사용하는 두 가지 방법을 제안한다. 본 논문에서 제안하는 방법은 대상(target) 문서와 증거로 주어진 출처(source) 문서 사이의 상대적(relative) 정보를 추출하여 신규성을 분류할 대상 문서의 특징 벡터를 구성하는 것에 초점을 맞춘다. 본 논문에서는 표준 벤치마크 데이터 셋인 TAP-DLND 1.0를 이용하여 여러 실험을 통해서 제안한 방법의 우수성을 보여준다.
