Previous studies have reported that a plausible reference point has a greater anchoring effect than an extreme reference point. It is also known that the anchoring effect decreases when the individual's level of knowledge related to a given item is high. However, there has been no study examining the interaction of the plausibility of the reference point and the difficulty of the given question. Therefore, in this study, the effect of the reference plausibility and the difficulty of the questions on the anchoring effect were examined. The relationship between the response confidence and the anchoring effect was also examined. To do so, easy and difficult questions, plausible and extreme reference points were selected through preliminary research. The experiment was conducted following the 'standard anchoring task procedure'. As results, the extremity of the reference point and the difficulty of the question affected the size of the anchoring effect respectively. The difficulty of the question also affected the confidence of the response. Specifically, when a plausible reference point was presented and when a difficult question was presented, the anchoring effects were increased. In addition, the lower the confidence in one's performances, the greater the influence of the reference point when an extreme reference point was presented. These results show that the plausibility of the given reference point and the difficulty of the item have different effects on the magnitude of the anchoring effect and the degree of confidence. The results of this study support the attitude change perspective regarding the anchoring effect, which suggests that the anchoring effect varies depending on the characteristics of the reference point and the individual's knowledge.
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'.

With the improvement of the nutritive conditions and the influence of overflowing informations and various cultural aspects imported from foreign countries, children develop more rapidly in the bodily and sexual growth. This study was conducted to suggest some ideas useful in planning sexual education program in elementary schools and ultimate aim is to promote sexual health. The subject of this survey consisted of 802 fourth, fifth, sixth graders from 6 schools in Seoul, Hongchon and Chunchon. Major findings are summarized as follows. 1. The degree of sexual knowledge of children showed low averaged 26.96 and the degree of sexual attitude showed usual averaged 55.70. 2. With the respect to the demographic characteristics, there were stastically significant differences in sexual knowledge, according to children's grade(F=64.031, p=. 000), father's education(t=-2.504, p=.013), experience of menarche(t=3.470, p=.001), experience of sex-related question to their parents(t=-.6054, p=.000), experience of sex-related question to the teachers (t= -3.385, p=.001), experience of sexual education(t=8.607, p=.000) and in sexual attitude, there were stastically significant differences according to children's grade (F=6.588, p=.001), experience of sex- related question to their parents(t=-5.387, p=.000), experience of sex-related question to the teachers(t=-2.845, p=.005), experience of sexual education(t=5.070, p=.000). 3. The level of sexual knowledge and sexual attitude of childrens'was correlated at significant level(r=.354, p=.000) The findings of this study indicated that variety of the systematic sexual education program suitable for the stage of children should be developed and family, society, contry's higher concern and enlightment are required.

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'.
Although there are various cultural events and cultural contents produced in the region, there is a lack of distribution and spread of regional information to expand related economic consumption. This study combined local advertising by local advertisers with the knowledge search method in question and answer format from a location-based service perspective for the purpose of spreading and using local cultural information. The approach looked at domestic and international cases of knowledge search based on region and location-based advertising research, presented community model of location inquiry based information service and revenue model of local advertisement. Through this, this study designed a question and answer based community and operational structure model of local advertising, and developed an information service system in the form of prototyping. By extending the distribution of question and answer data among users to location information, it is meaningful that a business service model was presented that combines local cultural content information and the demand for user access with the revenue model of local advertising.

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.
