전통적인 고객지원방법에서는 콜 센터와 서비스 센터가 고객의 질문과 요구 사항을 접수하고 응대하는 기능을 담당해왔다. 최근 인터넷의 급속한 확산에 따라 전화, 우편, 방문 등의 전통적인 고객과의 의사소통수단이 전자우편과 인터넷 게시판과 같은 웹기반의 고객지원시스템으로 전환되고 있다. 인터넷 게시판은 기본적으로 고객의 질문에 관리자가 응답하는 시스템이므로 고객이 응답을 받는데 시간이 걸리는 제약이 있다. 이러한 시간적 제약을 해결하기 위하여 고객이 인터넷을 통하여 고객지원시스템에 접속하여 미리 구축된 지식 데이터베이스로부터 원격에서 질문에 대한 응답을 받을 수 있도록 공통적인 질문과 응답을 FAQ와 같은 형태를 제공한다. 그리고, 인터넷 게시판에 다양한 내용과 형태의 질문이 혼재되어 사용됨으로써 응답과 관리상의 어려움이 많다. 따라서 질문들을 체계적으로 분류하여 FAQ를 만들고, 인터넷 게시판의 관리작업을 지원하기 위한 도구의 필요성이 대두되고 있다. 본 연구에서는 키워드와 키워드들간의 친밀도를 이용하여 벡터형태로 표현한 질문들간의 유사 도를 계산하여 질문들을 클러스터링 하는 방법을 제안한다. 제안한 방법은 기본적으로 자동으로 질문들을 분류하지만, 내용이 애매모호한 질문의 경우 사용자가 상호작용을 통하여 사용자의 판단을 받아들일 수 있도록 개발되었다. 그리고, 제안한 방법의 성능을 평가하기 위하여 프로토타입 시스템을 개발하고 제한된 상황하에서 실험을 수행하였다.

선행 연구들에서는 그럴듯한 기준점이 극단적 기준점보다 더 큰 기준점 효과를 야기하는 반면, 주어진 문항과 관련된 개인의 지식수준이 높으면 기준점 효과가 작아진다고 보고하고 있다. 하지만 제시되는 기준점이 그럴듯한지 여부와 주어진 문항 자체의 난이도가 기준점 효과에 미치는 영향을 함께 살펴본 연구는 없었다. 따라서 본 연구에서는 기준점의 극단성과 문항의 난이도가 기준점 효과에 미치는 영향을 살펴보았으며, 이에 더해 응답 확신도와 기준점 효과의 관계도 살펴보았다. 이를 위하여 예비 연구를 통해 쉬운 문항과 어려운 문항, 그럴듯한 기준점과 극단적인 기준점을 선정하였다. 본 실험은 '표준 기준점 실험 절차' 에 따라 진행되었다. 연구 결과, 기준점의 극단성과 문항의 난이도는 각각 기준점 효과에 영향을 미쳤으며 문항의 난이도는 응답 확신도에도 또한 영향을 미쳤다. 구체적으로, 그럴듯한 기준점을 제시했을 때와 어려운 문항을 제시했을 때에 기준점 효과가 크게 나타났다. 또한 자신의 수행에 대한 확신이 낮을수록 극단적인 기준점이 제시되었을 때 기준점의 영향을 크게 받았다. 이러한 결과는 기준점이 그럴듯한지와 문항의 난이도에 따라 기준점 효과의 크기와 확신 정도, 그리고 기준점 효과와 확신도 사이의 상관관계가 다르게 나타난다는 것을 보여준다. 본 연구의 결과는 기준점의 특성이나 개인의 상태에 따라 기준점 효과가 달라진다고 제안하는 기준점 효과에 관한 태도 변화 관점을 뒷받침한다.

Objectives : To evaluate the properness and effectiveness of the question categories concerning 'total physiognomy', used in Iksan Wonkwang Oriental Medicine. Methods: We statistically analyzed data from those 1335 patients focussing on 'relative discrimination ability' to sasang constructions and 'response ratio'. Patients included in this research are only those who had been well treated in Iksan Wonkwang Oriental Medicine during the Period of three years from 2000 to 2002. The data are obtained through the electronic chart developed by Kim Jong-Yeol, and analyzed using the statistical Package SPSS. Results: The first category for discriminating Taeum type, 'heavy and looking steady', has more discriminating power and effectiveness among women than men, and especially in wemen with an age of 21 or more. The second category for discriminating Soeum type, 'delicate and modest', is more discriminating and effective among men than women, and mostly among men with ages 21-40. The third category for Soyang type, 'fast and brave', is almost equally discriminating and effective to both women and men, especially among women with ages 40 or less and among men with ages 21 or more. Finally, the forth category for discriminating Taeyang type, 'progressive', is neither discriminating nor effective among most the women than men in all age groups. Conclusions: The definition of 'relative discriminating power of constitution' and 'response ratio' are well evaluating the properness and effectiveness of the question categories regarding 'total physiognomy'. The first category is most discriminating and effective among women with ages 20 or less, and the second among 21-40 year old men, the third among women with ages 40 or less and among men with ages 21 or over. The forth category is neither discriminating nor effective.

Korean versions of British Medical Research Council (MRC), Cornell Medical Index(CMI), and American Thoracic Society 78 (ATS-DLD-78) respiratory questionaires were compared with each other, and were tested the stability, in terms of test-retest reliability, of each questions by self-administration of those to 156 medical students. The results obtained and conclusions drawn are as follow: 1. The degree of agreements between responses to the comparable questions of CMI vs MRC, and of CMI vs ATS-DLD-78 were not satisfactory. There were, however, $71{\sim}100$ per cent of agreement between responses to the questions on Cough, Wheezing, Phlegm, Breathlessness, and Chest illness of ATS-DLD-78 vs MRC questionaire. And the ATS-DLD-78 tended to yield greater number of positive responses than MRC (See Table 4). 2. All of the coefficient of stability of each questions in 3 questionaires were statistically significant, ranged $77{\sim}100$ per cent, except that of the question on episode of cough and phlegm in ATS-DLD-78 questionaire (See Table 5-1). The question is composed of two collateral conditions, 'lasting for 3 weeks or more' and 'each year'. 3. It can be insisted that the Section-B questions of CMI is not proper for use in epidemiologic survey on respiratory illness. And rather than MRC, the ATS-DLD-78 questionaire deserves to prefer to be used in epidemiologic studies on respiratory illness. 4. In question-wording, especially, of inquiring past experience, it is possible to lessen the reliability of the question that including collateral conditions such as 'the duration lasted of symptoms', and moreover, of which words are not common usage. For example, for Korean '10days' or 'half a month' is more familiar time unit rather than 'week'.

This research was done to gain the health information in one of the target areas(rural area) of the Korea University Community Health Project, and to improve and standardize the methodology of the health interview survey. There were two types of questions;one was the simple open-ended question and the other was check list in the interview survey for a total of 1,406 inhabitants. And so the result obtained from the above survey was analysed. The results as follows; 1) The morbidity rate in general was 11.2% by simple open-ended question and 32.5% by check list during recent 20 days in interview method. 2) Women had higher morbidity rate in both kinds of method. 3) The most prevalent diseases in the interview method using check list were the ones of the musculo-skeletal system and connective tissue (22.5%), and diseases of the respiratory system (19.8%) and digestive system (13.7%) were in order of frequency. 4) By the position in the family, housewives had highest morbidity rate in the interview method unrespectedly, and the reason seemed that the respondents were houseweives themselves and the morbidity rate was the one by spell not by person. But morbidity rate by the socio-economic status had no significant difference in both methods. 5) The agreement rate on simple open-ended question and check list was 72.5%, but if limiting respondents themselves only, the rate was falled to 54%. 6) The morbidities were diverse in the review of the results of previous morbidity surveies, but the morbidity rate was higher and less variable in case of using check list and getting the replies individually than using simple open-ended question and proxy respondents.

This study has a purpose mainly to analyze the team interaction change by the duration of time in the Capstone-Design activities according to MBTI Modes. Study objects are four students of Mechanical Engineering at School of Engineering in C University located in Daejeon, and the team interaction change was analyzed through IPA (Interaction Process Analysis) method. From the result, first, ESTP showed the change of increase in interaction by the time duration of initial, mid, late periods in 'social-emotional area: positive' and 'task area: question', and the change of decrease by the same time duration of periods in 'task area: solution'. Also, there was no change in 'social-emotional area: negative' because there was no interaction. Second, ESFJ showed the change of decrease in interaction by the time duration of initial, mid, late periods in 'social-emotional area: positive' and 'task area: question', and the change of increase by the same time duration of periods in 'task area: solution' and 'social-emotional area: negative'. Third, ISTJ showed the change of decrease in interaction by the time duration of initial, mid, late periods in 'social-emotional area: positive', 'task area: question' and 'social-emotional area: negative', and the change of increase by the same time duration of periods in 'task area: solution'. Fourth, ENFP showed the change of decrease by the time duration of initial, mid, late periods in 'social-emotional area: positive', 'task area: solution' and 'social-emotional area: negative', and the change of increase by the same time duration of periods in 'task area: question'.

Rhetorical relations between two text fragments are essential information and support natural language processing applications such as Question - Answering (QA) system and automatic text summarization to produce an effective outcome. Question - Answering (QA) system facilitates users to retrieve a meaningful response. There is a demand for rhetorical relation based datasets to develop such a system to interpret and respond to user requests. There are a limited number of datasets for developing an Arabic QA system. Thus, there is a lack of an effective QA system in the Arabic language. Recent research works reveal that unsupervised learning can support the QA system to reply to users queries. In this study, researchers intend to develop a rhetorical relation based dataset for implementing unsupervised learning applications. A web crawler is developed to crawl Arabic content from the web. A discourse-annotated corpus is generated using the rhetorical structural theory. A Naïve Bayes based QA system is developed to evaluate the performance of datasets. The outcome shows that the performance of the QA system is improved with proposed dataset and able to answer user queries with an appropriate response. In addition, the results on fine-grained and coarse-grained relations reveal that the dataset is highly reliable.

This study investigates the reliability of plagiarism measurement in the ESL essay writing context. The current study aims to address the answers to the following research questions: 1) How does plagiarism measurement affect test reliability in a psychometric view? and 2) how do raters conceive the plagiarism in their analytic scoring? This study uses the mixed-methodology that crosses quantitative-qualitative techniques. Thirty eight international students took an ESL placement writing test offered by the University of Illinois. Two native expert raters rated students' essays in terms of 5 analytic features (organization, content, language use, source use, plagiarism) and made a holistic score using a scoring benchmark. For research question 1, the current study, using G-theory and Multi-facet Rasch model, found that plagiarism measurement threatened test reliability. For research question 2, two native raters and one non-native rater in their email correspondences responded that plagiarism was not a valid analytic area to be measured in a large-scale writing test. They viewed the plagiarism as a difficult measurement are. In conclusion, this study proposes that a systematic training program for avoiding plagiarism should be given to students. In addition, this study suggested that plagiarism is measured reliably in the small-scale classroom test.
