시공간 조인은 이동객체와 같이 시공간의 특성을 가지는 데이터를 처리할 때 요구되는 중요한 연산자로, 이동객체들의 움직임을 분석하거나 이동객체들의 시공간적 패턴을 찾는 것과 같이 다양하게 활용된다. 현재까지 실외공간에서의 시공간 조인 질의에 관한 연구는 많이 진행되어왔다. 최근에는 실내측위기술이 발전함에 따라 실외뿐만 아니라 실내에서도 다양한 위치기반 서비스가 점진적으로 제공되고 있으며, 특히 이동객체를 중심으로 다양한 응용 서비스들을 필요로 하게 된다. 하지만 실내공간에서의 시공간 조인에 관한 연구는 아직 전무하다. 본 논문에서는 실내공간에서 실시간으로 갱신되는 이동객체에 대한 연속 시공간 셀프조인 질의와 질의처리 방법론을 제안하였다. 연속 시공간 셀프조인 질의는 주어지는 특정 시간과 공간의 조건을 만족하는 모든 쌍들을 시간이 지남에 따라 지속적으로 갱신하는 질의이다. 본 논문에서는 방이나 복도와 같이 특정한 기호를 중심으로 이동객체의 위치를 표현하며 이러한 특징을 가지는 공간을 기호공간이라 한다. 그리고 방대한 스트림데이터를 효과적으로 필터링하고 관리하기 위한 후보쌍 버퍼 테이블이라는 자료구조와 이를 활용한 질의처리 방법론을 제안하였으며 실험을 통해 타당성을 검증하였다.

소프트웨어 테스팅이 소프트웨어 개발 비용의 상당 부분을 차지하는 것은 잘 알려진 사실이다. 소프트웨어 테스팅 비용을 줄이기 위해 소프트웨어 테스트 데이터를 자동으로 생성하는 방법에 많은 연구가 이루어지고 있다. 일반적으로 테스트 데이터 자동 생성을 지원하기 위해 심볼릭 실행기나 제약 해결기와 같은 정교한 도구들을 요구한다. 그러나 이와 같은 도구들을 개발하거나 구입하는 것은 소프트웨어 테스트 관련 비용을 증가시키는 또 다른 요소로 작용된다. 이 논문에서는 심볼릭 실행이나 제약 해결에 의존되지 않는 동적 테스트 데이터 방법을 제안한다. 제안된 방식은 분기 커버리지 기준을 효과적으로 만족하도록 Korel의 경로 지향 테스트 데이터 생성 방법을 확장한다. 이 논문에서는 삼각형 분류 프로그램에 대한 실험을 통하여 제안된 방법이 분기 커버리지를 매우 효과적으로 달성함을 보인다.

The purpose of this study was to identity the relationship of clothing involvement, consumer characteristics, and clothing buying behavior of college female students in China. A questionnaire was developed to measure clothing involvement, materialism, conspicuous consumption, reference group influence, clothing purchasing modes, fashion information sources. The questionnaire was administered to 390 college female students in Dandong of china. The data were analyzed using percentage, frequency, factor analysis, and t-test. The results of the study were as follows: 1. Subjects were divided into low clothing involved and high clothing involved groups according to the level of clothing involvement. 2. Three dimensions of materialism were derived by factor analysis such as Happiness-pursuing, Life-centered, and Sucess-symbolic. And three dimensions of conspicuous consumption and reference group influence were derived by factor analysis such as luxury oriented, Status symbolic, Brand-name oriented, and Comparative, Informational, Normative exactly. Clothing purchasing motives and fashion information sources were factor analysed as Social and Individual mole, and Printed & Electric-wave media, Marketer managed, Personal exactly. 3. There were significant differences between high involved and low involved consumers in consumer characteristics and clothing purchasing behavior. The high involved consumers showed more importance than low involved consumers about materialism especially in Happiness-pursuing about conspicuous consumption in status symbolic and about influence of reference group in comparative. The high involved consumers put more importance than low involved consumer individual motive as clothing purchasing motive, and marketer managed in clothing fashion information. The high invoked consumers showed more importance than low invoked consumers about evaluating attributes of product, and about store patronage criterion.

Interval-valued data, a type of symbolic data, is given as an interval in which the observation object is not a single value. It can also occur frequently in the process of aggregating large databases into a form that is easy to manage. Various regression methods for interval-valued data have been proposed relatively recently. In this paper, we introduce a nonparametric regression model using the kernel function and a nonlinear regression model for the interval-valued data. We also propose applying the local linear regression model, one of the nonparametric methods, to the interval-valued data. Simulations based on several distributions of the center point and the range are conducted using each of the methods presented in this paper. Various conditions confirm that the performance of the proposed local linear estimator is better than the others.

One of the common issues in large dataset analyses is to detect and construct homogeneous groups of objects in those datasets. This is typically done by some form of clustering technique. In this study, we present a divisive hierarchical clustering method for two monothetic characteristics of histogram data. Unlike classical data points, a histogram has internal variation of itself as well as location information. However, to find the optimal bipartition, existing divisive monothetic clustering methods for histogram data consider only location information as a monothetic characteristic and they cannot distinguish histograms with the same location but different internal variations. Thus, a divisive clustering method considering both location and internal variation of histograms is proposed in this study. The method has an advantage in interpreting clustering outcomes by providing binary questions for each split. The proposed clustering method is verified through a simulation study and applied to a large U.S. house property value dataset.

Whitehead's discussion of language is not to be found in any one book or article. It is interwoven with his discussion of many other questions. He was, however, greatly concerned with the problem of symbolism in general and the uses of language. He regards language, spoken or written, as an instrument devised by men to aid them in their adjustment to the environment in which they live Language is used for many specific purposes in the process of this adjustment. Words are employed not only to refer to data and to express emotions. They may be used also to record experiences, and thoughts about these experiences. Worts also function as instruments in the organization of experiences as they are considered in retrospect. Thus words free us from the bondage of the immediate. And Whitehead's theory of meaning is implicit in his discussion of the functions of language. According to him, the human mind is functioning symbolically when some components of its experience elicit consciousness, beliefs, emotions, and usages, respecting other components of its experiences. The former set of components are the 'symbols', and the latter set constitute the 'meaning' of the symbols. Whitehead points out that one word may have several meanings, i.e. refer to several different data. In order to understand, thus, the meaning to which a word refers, it is sometimes very important to appreciate the system of thought within which a person is operating. Further, Whitehead's discussion of language includes a number of cogent warning the deficiencies of language, and hence the need for great care in the use of words. In fact, language developed gradually. For the most part we have created words designed to deal with practical problems. Attention focuses on the prominent features in a situation, in particular the changing aspects of things. With reference to such data our words are relatively adequate. However, this issues in an unfortunate superficiality. The enduring, the subtle, the complex and the general aspects of the universe do not have adequate verbal representation. for this reason, Whitehead's position concerning the uses of language in speculative philosophy is stated with pungent directness. The uncritical trust in the adequacy of language is one of the main errors to which philosophy is liable. Since ordinary language does not do justice to the generalities, profundities and complexities of life, it is obvious that philosophy requires new words and phrases, or at least the revision of familiar words and phrases. Proceeding to develop the theme Whitehead contends that words and phrases must be stretched towards a generality foreign to their ordinary usage. In the same vein Whitehead refers to the need to realize that language which is the tool of philosophy needs to be redesigned just as in physical science available physical apparatus needs to be redesigned. But even these words and phrases, stretched or redesigned, are never completely adequate in philosophical speculations. They are, in his opinion, merely a great improvement over ordinary language or the language science, mathematics or symbolic logic.

How consumers perceives Korean heritage is the most essential motivation to purchase traditional products. This study investigates if there is a difference in the value perception of traditional culture on preferences for and the long-term relationship of Hanboks. It also investigates differences in the preference and consumption behavior of Hanboks depending on the degree of experience for Hanbok. For this research purpose, data were collected from 745 residents between the ages of 20-60 in the Seoul and metropolitan areas through online and offline surveys. The data were analyzed by descriptive statistics, factor analysis, and path analysis, using the SPSS-WIN 20.0, AMOS 20.0 program. The value recognition toward traditional culture derived aesthetic and symbolic factors. The result of grouping according to the experience of the Hanbok indicated that the two groups of traditional cultural values influenced preferences for Hanboks. In the middle group, only the symbolic value had a significant influence on the preference of Hanbok. It was found that the less experienced group had no traditional culture value factor which had a significant effect on the preferences for Hanboks. Based on the results of this study, it is expected to be used as basic data to establish a marketing strategy to increase the preferences for traditional culture such as Hanboks by increasing various traditional culture experiences as well as Hanboks.

The purpose of this study is to research the similarity and difference of color application in the culture of Korea and Japan. The subject of this research is the costume color of Changgeuk and Kabuki. This survey analyzes Munsell's 3 attributes(Hue, Value, Chroma), tone, and 3D color analysis by extracted color data. And representative color according to Obangsaek is proposed. The results of this study are as follows: 1. High chroma red in Kabuki costume is more used as symbolic color(passion and luxurious) in order to show character's personality than that in Changguek costume. 2. Low chroma YR color(no-dyeing color) in Changgeuk costume much more used because of Korean white robe preference and eco-friendly thinking. But high chroma yellow is restrictive color for symbolic color of emperor in Korea and Japan. 3. Blue is most frequently used in both costumes because blue is encouraging color by the theory of exponents of the five elements doctrine. 4. White in Korean Changguek costume is more used for white robe preference thinking, but black in Kabuki costume is much more used for symbol of power in Japan. The similarity of Korean and Japanese cultural color is to use much Obangsaek, less Ogansaek by the theory of exponents of the five elements doctrine, but the difference of Korean and Japanese cultural color is to use color differently according to preference thinking system.

Purpose - Present study investigates character identification and emotional response to character that may affect consumers' intention to purchase the character-attached products. And this study explores whether symbolic relevance and object relevance affect the character identification, and whether character attractiveness and character salience affect the emotional response to characters. Research design, data, and methodology - SNS characters, animated characters, game characters, and traditional characters were used as experimental characters. And stationery as experimental product was used. 250 college students participated in the empirical study, and structural equation model was used to verify hypotheses. Results - First, the character identification and emotional response to characters affected the intention to purchase the products positively, and the emotional response to characters also positively affected character identification; second, symbolic relevance had no positive impact upon character identification, while object relevance had positive influence on character identification; and third, character attractiveness and salience had a positive effect on the emotional response. Conclusions - Present study contributes to the progress of character theories. Marketers should find ways to increase consumers' object relevance to characters and the level of characters' attractiveness and salience in order to promote the intent to purchase the products.
