  • 본 연구에서 구현하 SLWES(Sampling Learning Web Expert System)은 인터넷 환경에서 표본조사의 학습과 실제 표본조사 자료로부터 모수를 추정할 수 있도록 웹 프로그래밍 기술과 HTML을 결합하여 학습시스템과 통계계산 시스템, 그리고 전문가시스템으로 구성된 표본조사 학습전문가 시스템이다. SLWES는 표본조사에 대하여 전문 지식이 없거나 통계패키지 사용에 익숙하지 않은 비전문가들에게 표본추출법, 무수측정 표본크기 결정 등 표본조사에 대한 이론 학습과 실습의 기회를 인터넷 환경에서 직접 제공함으로써 사용자의 지식에 따라 표본조사론에 대해 체계적이고 효과적으로 학습할 수 있는 시스템이다. 또한 SLWES는 실제 표본조사의 표본추출에 적용될 수 있고 수집된 자료로부터 모수를 추정할수 있으므로 표본조사에 활용될 수 있다.

  • It is true that there is a possibility of distortion in the statistical surveys or actual surveys depending on which investigator, what purpose, and how research method. Even statistical results are more likely to be 'lying', and statistics on crime or delinquent are sometimes referred to as 'whopper'. There are many reasons for not trusting statistics on crime or delinquent, but one of the main causes is the existence of a hidden crime or an unreported crime. In order to overcome these hidden crime problems, victim surveys or self-report surveys are being used. However, this method also has the problem of underreporting or overreporting depending on the type of crime. Because investigations into crime, delinquency, and deviant behavior are very sensitive, the subjects have a psychological burden. A randomized response model has been developed and used in the field of statistics as a way to induce a true answer to the sensitive content which is burdensome to reveal the experiences of the survey subjects. This technique is a very useful way to solve the problems of victim surveys or self-report surveys. Nevertheless, there are very few cases in the field of criminology in Korea. Therefore, in order to examine the applicability of the randomized response model in the field of criminology, this study used the randomized response model to actually measure the content of prostitution for college students and the effectiveness of the randomized response model was confirmed.

  • This paper studied the statistics such as the total number of syllables: the kinds of syllables: the frequency of syllables, the total number of eojeols, the kinds of eojeols(word phrases unique in Korean language), average length of eojeols and the frequency of eojeols in four different Korean textbooks for 7th-grade students. The results of the statistical survey are as follows: the number of syllables was 286,801; the kinds of Korean syllables were 1,350; the average frequency of syllables was 212.4; the number of eoieol was 109,393; the kinds of eoieol were 29,356; the average frequency of eojeol was 3.7; the average length of eojeols was 2.7 syllables, the longest one consist of 8 syllables.

  • The advantage of an internet survey is the speed with which data can be accumulated from respondents. And this method is more economical, provides more accurate information, and has greater scope in subject coverage. Since there is used multi-media, the design of questionnaires is even more important in order to achieve high data quality.

  • It is desirable to use a monthly benchmarked construction indicator which contains the characteristics of statistical data in an annual survey in order to analyze the cyclical phenomenon of the construction activity. The benchmarked indicator is expected to improve the data quality in terms of accuracy, consistency, comparability, and completeness. In this paper, benchmarking methodologies of compiling monthly construction indicators arc researched by using a monthly prompt data holding short - term fluctuations and an annual survey data regarded as more accurate statistics than monthly data. The benchmarking is the methodology by which a high frequency data should he adjusted in order to hold the short-term and cyclical phenomena, and the long - term trend of two data groups with ensuring the consistency of an annual summation between a high frequency data and a low frequency data. This paper considered the numerical approach like pro rata distribution method, proportional Denton method, EFL or HP filter Benchmark - to - Indicator ratio method, and the model - based approach such as Chow and Lin method, $Fem{\acute{a}}ndez$ method. Also, the benchmarked construction indicators were estimated by early mentioned benchmarking methods with practical data, and these methods were empirically reviewed and compared. In case of construction indicators with severe seasonal fluctuations and irregulars, the numerical approach seemed to be performed more correctly than the model- based approach. Among numerical methods, the proportional Denton method used in general was a little nice. The HP filter Benchmark - to - Indicator ratio method may be considered with survey errors or measurement errors in an annual survey data.

  • This study aims at improving teaching and learning abilities on the courses of probability/statistics in the fields of the S/W and H/W. In order to do this, this paper firstly conducts a survey which measures the perception of the surveyees' necessity of the related courses, and includes the contents that the related courses should cover. Secondly, this paper analyzes the educational effect on the achievement by studying Pattern Recognition, a major course of S/W and H/W, with combining probability/statistics or data analysis. Lastly, this paper suggests the promising pedagogical method for educating probability/statistics by using a survey and the case studies. In this way, this paper shows the necessity of probability/statistics for acquiring a new technology and the flexible approach of various subjects.
