  • This study considered network quotient (NQ) of deluxe hotel employees and schematized characteristic attributes of being selected by employees with image through correspondence analysis in terms of cognition degree. Self-administrated questionnaires were completed by employees (292 samples) and data were analysed by frequency, t-test, one-way ANOVA, reliability and correspondence analysis. First, the hotel employees indicated the high average value in "participating in special education or seminar for improving ability ($3.85{\pm}0.76$). Second, as a result of analyzing difference according to gender, the average value in men was higher than in women. It was indicated that the higher age and career lead to a rise even in the average value of relationship index. Third, in consequence of carrying out correspondence analysis in order to prepare image map according to cognition level on relationship index in hotel employees, the measurement item that is placed in the closest distance to the response as saying of not so very was the response as saying of "having a lunch (dinner) engagement twice or three times a week." On the other hand, the response as saying of "tending to have many acquaintances compared to coworkers" was schematized in the close distance to the response as saying of very so.

  • 초등학교 수학에서 '규칙과 대응'은 함수 개념에 대한 기초적인 토대를 마련할 수 있다는 측면에서 중요하지만, 관련 연구는 많지 않다. 이에 본 연구에서는 선행 연구를 분석하여 규칙과 대응을 지도하기 위한 핵심 교수 학습 요소를 도출하였으며, 이를 바탕으로 2007 개정 수학 교과서 및 2009 개정 수학 교과서에 제시된 규칙과 대응 관련 단원을 분석하였다. 구체적으로 실생활 맥락의 반영, 다양한 유형의 패턴 과제 활용, 두 양 사이의 대응 관계 탐구, 변수를 사용한 관계 표현에서의 의미 지도 측면에서 규칙과 대응 관련 단원을 비교 분석하였다. 분석 결과, 실생활 맥락의 반영은 두 교과서에 대체로 잘 구현되어 있었으며, 다양한 유형의 패턴 과제 활용과 두 양 사이의 대응 관계 탐구는 부분적으로 구현된 편이었다. 한편 변수를 사용한 관계 표현에서의 의미 지도는 두 교과서에서 공통적으로 잘 구현되지 않았다. 이러한 결과를 바탕으로 규칙과 대응을 지도하는 방안 및 차기 교과서 개발 방향에 관한 시사점을 논의하였다.

  • Some multivariate analyses provide configurations for variables or objects in low dimensional space because we can see easily their relation. In particular, in simple correspondence analysis(SCA), we can obtain the various configurations which are called SCA Maps based on the algebraic algorithms. Moreover, it often occur the variability among them. Therefore, in this study, we will give a comparison of variability of SCA maps using the procrustes analysis which is a technique of comparing configurations in multidimensional scaling.

  • This paper provides a framework for semantic correspondence of heterogeneous databases using self- organizing map. It solves the problem of overlapping between different databases due to their different schemas. Clustering technique using self-organizing maps (SOM) is tested and evaluated to assess its performance when using different kinds of data. Preprocessing of database is performed prior to clustering using edit distance algorithm, principal component analysis (PCA), and normalization function to identify the features necessary for clustering.

  • Reliability measures of questionnaire and ${\chi}^2$ contingency tests of categorized responses are most practical tools to analyze the characteristics of subjects of survey study. This research evaluates the Cronbaha's reliability measures by using Repeated Measure Design (RMD) with illustrated MINITAB examples. In addition, ${\chi}^2$ statistics of each cell of categorized tables can be effectively interpreted with the symmetric plot of correspondence analysis. The practical example is also discussed to provide comprehensive understanding of topic.

  • The headline of advertisements holds the important position in advertisement recognition and receptivity. In this paper, we classified the headlines as several types with measuring the response effects for purpose of understanding the customer's behavior. Also we conducted the decision tree analysis and correspondence analysis. The decision tree shows the difference between responders and non-responders, and the correspondence analysis shows the relationship between the sales and the customer's demographic information.

현행 오장-오행 배속은 사상 논쟁의 산물인가 -"사기.창공열전"을 중심으로- (Did the current correspondence scheme between Five Viscera and Five Phases arise from social and humane hegemony conflict? -some clues from "Changgongyeoljeon(倉公列傳)" in "Sagi(史記)")

  • Traditional Chinese Medicine is based on Five Phase theory that link Liver, Heart, Spleen, Lung, Kidney to Wood, Fire, Earth, Metal, Water respectively. Recently, some argue that this correspondence scheme had been established by political or socio-humane issues in early Eastern Han dynasty. But according to our analysis on Changgongyeoljeon(in Sagi), it has been revealed that this scheme had their own history from early Western Han dynasty. So we may conclude that people with medical profession had preserved the current correspondence scheme in Five Phase theory regardless trends of literature and politics in Western and Eastern Han dynasty.

  • Background : To examine the difference between ICD-10 and The Korean standard classification of disease(oriental medicine), and to aim at improve the practical use as statistical data. It is one of the reason of disease classification. On that account we convert the many to many correspondence presenting classification of oriental medicine into many to one correspondence. Method : The study tracked out 155 patients discharged from the university hospital which is located in Gyeonggi Province and managing hospital and oriental medicine hospital from July to October this year. The period of this study was from August 1 to November 18. We compared correspondence between the two services' diagnosis(hospital services and oriental medicine hospital services) at the same time and attempted many to one correspondence classification. That is for production of statistical data. Result : We investigated the group which have had medical treatment experience of two kinds of services at the same time. The result of this investigation was that the same oriental medicine diagnosis used differently in western medicine diagnosis. 44.5% was accorded with western medicine diagnosis. Correspondence of the western medicine diagnose with the top of the Korean standard classification of disease(oriental medicine) list's western medicine diagnosis was 13.5%. For many to one correspondence classification for statistics, one western medicine diagnosis was selected for one oriental medicine diagnosis. In case of the main diagnosis(I sign) was not enough to explain oriental medicine diagnosis' characteristic, we chose multiple other diagnosis, so other diagnosis(II sign) about patient's cause of disease could be selected for supplement after we examined the patient's records. The statistics was possible with this many to one correspondence. Conclusion : The result of this study about correspondence between western medicine diagnoses and those of oriental medicine confirms that The Korean standard classification of disease(oriental medicine) is hard to be standardized with western medicine diagnosis. Therefore, according to this study, we use new many to one correspondence classification, multiple oriental medicine diagnoses with one ICD-10, which can be used by statistical data.

  • This study investigated and compared the brand personality of domestically run family restaurants with quick service restaurants. Information was elicited from respective patrons using self-administered questionnaires which asked questions on recognizable brand characteristic and attributes of each restaurant through image maps. Data from the self-administrated questionnaires were collected and analysed using comparative statistical analysis, including frequency, t-test, chi-square, factor analysis, reliability analysis and correspondence analysis. Overall, patrons identified 5 factors which they used to rank individual restaurants; sophistication, competence, likeableness, trendiness, and ruggedness. Overall results showed the family restaurants that scored highly on likeableness and trendiness were Outback and TGIF. Furthermore, Vips was the only family restaurants that scored highly in ruggedness. In relation to quick service restaurants, Lotteria scored highest for competence while McDonalds and Burger King scored best for sophistication. Limitations and future research directions are also discussed.

  • 본 연구는 SNS 이용환경의 변화 및 사용자 증가에 따라 SNS 사용자들을 대상으로 이용 행태를 조사하였다. 사회인구변인에 따른 사용자의 SNS 이용 동기, 선호하는 SNS 유형, 주로 이용하는 SNS 서비스에 대해서 교차 분석을 통해 살펴보았고 SNS 사용자의 특성과 주로 이용하는 SNS 서비스에 대하여 대응일치분석을 실시하였다. 분석 결과 국내 SNS 사용자들의 이용 동기는 관계형이 가장 많은 빈도를 차지했으며 선호하는 SNS 유형은 폐쇄형 SNS이고 주로 이용하는 SNS는 카카오스토리인 것으로 나타났다. 또한 연령별, 직업별로 SNS 이용 동기에 유의한 차이가 있었으며 성별, 연령별로 선호하는 SNS 유형에 유의한 차이가 있는 것으로 나타났다. 마지막으로 SNS 사용자 특성별 주로 이용하는 SNS에 대한 이미지 맵을 시각적으로 고찰하기 위해 대응일치분석을 실시한 결과 연령별, 직업별, 선호하는 SNS 유형별로 주로 이용하는 SNS 서비스에는 차이가 있는 것을 발견하였다. 또한 대응일치분석 결과 SNS 서비스간의 경쟁관계가 어떠한 구도로 형성되어 있는지를 확인하였다. 이러한 결과를 바탕으로 시사점과 향후 연구 과제를 제시하였다.
