과학기술 분야의 한글 문헌에서는 외래어나 영어가 자주 출현한다. 하나의 영어 단어는 다양한 형태의 외래어로 표기되므로 동일 원어(source language)에서 나온 모든 외래어는 정보검색의 측면에서 하나의 대표어로 색인되어야만 한다. 본 논문은 표기는 다르지만 같은 원어에서 나온 외래어에 대하여 등가부류를 구축하는 방법을 기술하고, 정보검색에서 제시된 방법이 얼마나 큰 효과를 발휘하였는지에 대한 실험 결과를 제시한다. 정보 검색시 외래어와 이에 해당하는 영어를 동일한 의미로 취급할 때 검색 효과에 주는 영향을 파악하기 위해서 실험한 결과 11-포인트 평균 정확도(11-point average precision)면에서 약 50%의 검색성능의 향상을 보였다.

This study investigates the effect of adolescent dining habits on their physical development. We selected 200 students from the three high schools in Taejon, and surveyed with a questionnaire and collected data concerning physique from school health records. The results obtained from this study were as follows: 1. A point of intersection of two development trends of male and female students' heights was between sixth grade of elementary school and first grade of middle school. Two development trends of weights didn't have a point of intersection and male students' development trend of weights was a little higher than that of female students. 2. There were significant differences in the weight and BMI of male students. The 'regular dining' group had heavier weight and higher BMI than the other group, and the 'Eating only favorite food' group had lower weight and BMI than the other group. In female, heights of 'three meals a day' group were higher than that of 'two meals a day' group and the more snacks per day, the higher students' height was. 3. The 'regular exercise' group had significantly heavier weight and higher BMI than the other group amount females. 4. 'Regular dining' and 'Eating habits' had a positive linear relationship with male students' weight and BMI. 'Number of times of snacking' has a positive linear relationships with female students' height and a negative linear relationship with female students' BMI. Since dining habits of adolescents have not only an effect on their development but also later adults' health, to develop good habits of health and dining is a critical issue.
