本文研究共同特性对于无选择权的影响, 并涉及到了调节焦点理论. 本文主要着眼于这三个因子以及他们之间的关系. 之前的研究已经广泛涉及到这三个方面. 第一, 共同特性影响已经被广为研究. Tversky (1972) 开创了这个理论, EBA 模型: 通过消除方面. 根据这个理论, 消费者在比较的过程中更易于注意特殊的特性, 而忽略共同特性. 最近, 更多的研究开始针对于此模型对于消费者行为的影响. Chernev (1997) 认为增加共同特性可以减少选择距离. 但是, 随后Chernev (2001) 的研究指出共同特性可能是消费者认知上的负担, 所以他们更喜欢启发式的过程而不是系统式的过程. 这些研究提出了一系列问题: 共同特性是否影响顾客选择? 如果是的话, 这些影响是什么样子的? 第二, 一些研究指出没有选择的状况是消费者最好的选择, 他们在犹豫不决时用这种方法回避选择. 其他关于这一理论的研究是时间的压力, 消费者自信, 以及可供选择的数量. 第三, 调节聚焦理论在目前非常流行. 消费者有两个焦点目标: 促进和制止. 促进聚焦主要和希望, 野心, 成功, 获得等有关; 而制止聚焦和责任, 职责, 安全, 规避等有关. 调节聚焦理论预测了顾客的感情, 创造, 态度, 记忆, 表现, 和判断. 而这些都是市场营销研究的领域这些文献为本文的研究提供了一些理论支持. 特别是增加共同特征而不是忽略他们可以增加选择过程中克制消费者的没有选择状况的比重, 其对于促进消费者的作用确实相反的. 本文通过两个试验进行验证. 第一个是2 X 2 组间的设计(共同特性X调节聚焦), 数码相机作为相关的客体. 特别的是, 调节聚焦变量是从11个问题中取得的. 共同特性包括焦距, 重量, 记忆卡, 电池, 而像素和价格作为独特特性. 结果证明了我们的假设, 那就是增加共同特性增加了克制消费者的无选择比重, 而对促进消费者没有作用. 第二个试验被用来复制第一个实验的结果. 这个实验和之前的基本相同, 只有两个方面不同—主要控制和研究客体. 在促进的前提下, 研究对象必须一些词例如: 利润, 野心, 高兴, 成功, 发展等. 在克制的前提下, 他们必学写下坚持, 安全, 保护, 规避, 损失, 责任等词. 实验证明我们假设是成立的. 本研究说明了共同特性对于顾客选择的二重效果. 增加共同特性可以提高或者降低无选择状况. 本文对于理论研究和实践上都有着贡献. 对于市场营销人员来说, 他们可能需要根据顾客的划分来考虑产品的共同特性. 理论上, 研究结果支持共同特性和无选择状况的调节变量. 最后, 本文也有一些不足, 例如过于强调态度的重要性等. 我们希望本文能够为未来的研究做出抛砖引玉的作用.

In this paper we overview the literature on common features analysis of economic time series. Starting from the seminal contributions by Engle and Kozicki (1993) and Vahid and Engle (1993), we present and discuss the various notions that have been proposed to detect and model common cyclical features in macroeconometrics. In particular, we analyze in details the link between common cyclical features and the reduced-rank regression model. We also illustrate similarities and differences between the common features methodology and other popular types of multivariate time series modelling. Finally, we discuss some recent developments in this area, such as the implications of common features for univariate time series models and the analysis of common autocorrelation in medium-large dimensional systems.

This study examined testing condition when consumers have a strong ordinal preference and in a absence of established ordinal for a given attribute, how adding common features to two brands in a given product category affects brand choice. Research findings presented in this study are generally consistent with the preference confirmation view of choice. The data provides support for the proposition that (1) the effect of common features is moderated by the relative importance of brand attributes(Hypothesis 1) and (2) in the presence of primary attribute adding common features increases the likelihood of choosing the brand with the best value on this attribute(Hypotheses 2).

Scheduled inspections of common crossings are one of the main cost drivers of railway maintenance. Prognostics and health management (PHM) approach and modern monitoring means offer many possibilities in the optimization of inspections and maintenance. The present paper deals with data driven prognosis of the common crossing remaining useful life (RUL) that is based on an inertial monitoring system. The problem of scheduled inspections system for common crossings is outlined and analysed. The proposed analysis of inertial signals with the maximal overlap discrete wavelet packet transform (MODWPT) and Shannon entropy (SE) estimates enable to extract the spectral features. The relevant features for the acceleration components are selected with application of Lasso (Least absolute shrinkage and selection operator) regularization. The features are fused with time domain information about the longitudinal position of wheels impact and train velocities by multivariate regression. The fused structural health (SH) indicator has a significant correlation to the lifetime of crossing. The RUL prognosis is performed on the linear degradation stochastic model with recursive Bayesian update. Prognosis testing metrics show the promising results for common crossing inspection scheduling improvement.

The purpose of this study is to analyze common features and methodological differences of PN-spatial characteristics found in architectural theories and works of contemporary young architects in Japan, such as Sou Fujimoto, Yo shimada, Keisuke Maeda and Junya Ishigami. These architects have paid attention to space between nature and inner space and have tried to establish their own architectural theory on that. Such space is ambiguous and PN-spatial in a way that it has features of both nature and inner space. Ambiguousness is a characteristic of modern architecture and PN-spatial characteristics are one of the features of Japanese architecture. This study aims to analyze the architectural theories and works of contemporary young architects in Japan from the perspective of PN-space and to draw methodological differences and common features. Their theories and works have common features in terms of 'ambiguous spatial boundary', 'unregulated spatial territory', 'detoured circulation' and 'architectural motifs', but each has their own methodology. To sum up, the works and theories of the Japanese young architects contain the philosophy and discourse of modern architecture in general. To be sure, they clearly have characteristics of Japanese architecture, which needs to be studied constantly.

To make use of surveying data obtained from different sensors and different techniques in a common reference frame, it is a pre-requite step to register them in a common coordinate system. For this purpose, we have developed a methodology to register IKONOS-2 Satellite Imagery using ALS data. To achieve this, conjugate features from these data should be extracted in advance. In the study, linear features are chosen as conjugate features because they can be accurately extracted from man-made structures in urban area, and more easily than point features from ALS data. Then, observation equations are established from similarity measurements of the extracted features. During the process, considering the characteristics of systematic errors in IKONOS-2 satellite imagery, the transformation function were selected and used. In addition, we also analyzed how the number of linear features and their spatial distribution used as control features affect the accuracy of registration. Finally, the results were evaluated statistically and the results clearly demonstrated that the proposed algorithms are appropriate to register these data.

본 연구는 범주속성들이 공통원인 혹은 공통효과 인과 네트워크로 연결되었을 때 인과강도에 따른 속성추론을 검증했다. 인과범주에서 속성추론을 검증한 기존 연구들은 인과관계의 방향, 연결된 속성의 개수, 원인 혹은 결과의 여부 등에 따라 고유한 추론 패턴이 나타남을 보여주었다. 다만 기존 연구들은 인과관계에 따른 추론패턴을 주로 탐색했으며 인과관계의 효과가 인과강도에 따라 어떤 변화를 보이는지 확인한 연구는 찾아보기 어렵다. 본 연구에서는 공통원인(실험 1), 공통효과(실험 2) 네트워크에서 인과강도에 따른 속성추론을 검증했다. 이를 위해 참가자들에게 속성들이 인과적 관련성을 가지는 범주를 학습하게 한 다음 속성추론 과제를 실시하도록 했다. 실험 결과 인과관계 뿐만 아니라 인과강도 역시 속성추론에 중요한 영향을 미쳤다. 인과강도가 강할 떄 공통원인 속성에 대해서는 추론이 약해진 반면 공통효과 속성에 대해서는 추론이 강해졌다. 또한 인과강도가 강할 때 공통원인이 존재하는 경우 결과속성들에 대한 추론이 강해진 반면 공통효과에서는 반대의 결과가 나타났다. 특히 공통효과에서는 인과강도가 강할 때 인과적 절감이 더 뚜렷하게 나타났다. 이 결과들은 인과적 범주에서의 속성추론에서 참가자들은 인과관계 뿐만 아니라 인과강도를 고려한다는 것을 일관성있게 보여준다.

The purpose of this study is to examine features of parts of Jikryung and relations among the features. Results of the study can be described as follows. 1. The short front and long rear of Jikryung was changed into the long front and long rear of the dress in the late 16th century. Kalgit of quasi-square style as double collar was changed into that of common collar in the late 16th century and then into common semi-circle collar in the early 17th century, when double Sup was also changed Into single Sup. Narrow sleeves of Jikryung were replaced by bean chaff-shaped in the late 16th century and then by wide ones in the early period of the next century. The shape of the side hem of Jikryung was changed from rectangle into trapezoid in the early 17th century Triangle-shaped Moo was changed into trapezoid-shaped one in the late 16th century and then again into triangle in the late 17th century 2. Changes in shapes of the parts of Jikryung were made with them correlated. The collar of Jikryung saw change in its form from double to common as its width was reduced. Double Sup was changed into single one and the narrow, short coat string into the long one as Jikryung became a dress needing less adjustment. The sleeves widened as the length of whajang increased. The side hem of Jikryung saw change in its shape from rectangular to trapezoidal one as its position was changed. Trapezoidal Moo was replaced by triangular one as the sleeve of Jikryung was changed in shape. 3. Changes in shapes of the parts of Jikryung influenced the aesthetic beauty of the dress itself In its first period, Jikryung was simple with long, slim silhouettes. In its second period, the dress was rich with increased volume. Finally in its third period, the dress was characterized by the harmony of simpleness and richness.

This study emphasizes a new senior housing type which can provide individual housing units and common facilities for retirees, particularly who will be retired from universities. It is called a university-based retirement community. This study conducted a questionnaire survey to investigate future residents' needs for architectural environments that included housing types, common facility features, and proximity, and also development methods in response to the university involvement levels. The survey questionnaire was administered in one national university in Korea. A total of 214 responses were valid for statistical analyses. Major findings are as follows: Over 65% of the respondents were willing to live in the university-based retirement community. Regarding the location of the community, they responded the community would not need to be located on campus. Preferred common facilities in the UBRC were indoor fitness centers, the shuttle bus stops connecting to the adjacent areas, and bath and sauna facilities. The respondents emphasized university's contribution toward offering educational programs for UBRC residents. Lastly, their responses to the university role and involvement in the development and construction process were identified. This study results are expected to provide essential information for facilitating the Korean model of university-based retirement communities in the future.

Nowadays, portable digital cameras such as smart phone cameras are being popularly used for entertainment and visual information recording. Given a database of geo-tagged images, a visual location recognition system can determine the place depicted in a query photo. One of the most common visual location recognition approaches is the bag-of-words method where local image features are clustered into visual words. In this paper, we propose a new bag-of-words-based visual location recognition algorithm using time-series streetview database. The proposed algorithm selects only a small subset of image features which will be used in image retrieval process. By reducing the number of features to be used, the proposed algorithm can reduce the memory requirement of the image database and accelerate the retrieval process.
