The effect of reducing flood magnitudes, flood stages, and flood damage by upstream reservoir regulation are investigated in this study. The analytical procedures which has been established newly, are treated through this study for 7 index stations and same numbr of reaches. The method of this study could be expressed briefly as following procedures. Using stage-frequency relations and the potential damage survey data, damage-frequency relations are established, and from this, average annual flood damages computed. By holding out portions of the floods with various amounts of flood control storage in 6 reservoirs in the basin, routing were made to establish modified stage-frequency relations. From damage frequency relation, average annual damages are computed with and without condition of each control volume. The study result are concluded as follows; (1) The relationtship of corresponding water level between nearby stations are useful tools to adjust error of the data due to observation error and change of the gaging location. (2) The number of records about 10 years could not be applied for the statistical methods of flood frequency analysis. (3) The regional skew factors are recommended to apply flood frequency study by the log-Pearson Type III method. (4) The effect of damage reductions are greatly affectedin accordance with the routed flood. Therefore application of the Typical Tributary Contribution Flood are reasonable for this type of study. (5) In the North Han, effect of damage reduction due to the lacation of control point are gradually increased from upstream to downward until the confluence of North and South Han. (6) In the South Han, control effect are increased from Chungju to Yeoju where the maximum effect are analyzed and then decrease gradually until the confluence. (7) Better hydrologic and topographic combinations for the flood control are existed in South Han to compare with North Han in this study results.

Private-Source Educational Expenditure in Korea : Analysis and Implications

Han, You-Kyung RESEARCH INSTITUTE OF CURRICULUM INSTRUCTION EWHA 2005 East west education Vol.22 No.-

Private educational expenditure means the sum of the expenses individual household paid for educational activities but not processed through official accounting procedure. It includes private tutoring fees, books, room and board, school supplies and so on. Private educational spendings per student in the year of 2001 is 1,999 thousand won in pre- schools, 2,368 thousand won in elementary schools, 2,261 thousand won in middle schools, 2,307 thousand won in general high schools, 1,360 thousand won invocational high schools, 1,938 thousand won in junior colleges, 2,216 thousand won in industrial universities, 2,673 thousand won in four-year colleges and 2,330 thousand won in graduate schools. Total private educational expenditure estimated from these sample figures is 18,782 billion won for pre-school, middle school and high school students together and 7,891 billion won for students in higher education institutions. What we are most concerned about regarding the private educational expenditure is the amount of expenditure for the private tutoring. The percentage of private tutoring expenses on the average is about 48.6. Private educational spending per student has declined compared to the spending in 1998. Especially the spending for elementary school students, general high school students and college students had declined greatly. However, the spending for middle school students, vocational high school students and junior college students has slightly increased. The portion out of GDP also declined to 5.61% in 2001 from 6.53% in 1998.

男女大學生의 結婚觀(II) : 그들의 意識과 行動을 中心으로

柳時中,韓有常 경북대학교 사회과학대학 1984 社會科學 Vol.3 No.-

The purpose of this study is to examine some attitudes that college students assume toward marriage. In the article "College Students' Attitudes Toward Marriage: Their Spouse Selection Routes and Criteria" (Yu and Han, 1984) to appear in Oriental Culture Research, vol.11 (1984), the authors have advanced an analysis of prevailing spouse selection routes and criteria. As a sequel to Yu and Han (1984), this study tries to investigate problems concerning premarital sexual intercourse and postnuptial life planning that enter into the spouse selection process. Since Korea began to modernize itself, diverse changes have occurred in our society. Particularly, the Western free-sex trend seems to have continued its infiltration to such an extent that college students in Korea are seriously affected by the mood. Upon investigation, however, it has been found out that most college students still impart a high value to premarital virginity, and that only a small number of students are actually experiencing premarital coitus. Questionaires about postnuptial life planning were employed to analyze the attitudes that college students take toward independent family life, residence problem, double-income family, and family planning. The result was that the nuclear and double-income family was more favored by female students. It also turned out that, regardless of sex, most college students hoped to find their postnuptial residence in cities and to have fewer children than before.

본 논문에서는 전도성을 띠는 도전사(electro-thread)를 이용하여 UHF 대역(860∼960 MHz)에서 동작하는 T-정합 다이폴 형태의 RFID Tag 안테나를 디자인하였다. 일반적으로 심벌에 적용하기 쉬운 형태로 한글 자음 ‘ㅂ’과 유사한 모양으로 설계하고 제작하였다. 기존의 구리 기판이나 구리 테이프를 이용하여 만든 것과는 달리 도전사 RFID 태그 안테나는 착용감, 구부러짐 변화에도 문제가 없고 물에 젖어도 문제가 없는 장점을 지니고 있다. 우선, 제작한 안테나의 특성을 검증하기 위하여 도전사 RFID 태그를 물, 소금물과 비눗물에 충분히 적신 후 태그로 제대로 작동하는지 알아보기 위해 인식거리를 측정해 보았다. 측정한 결과 인식거리는 조금 떨어지지만 태그로서 충분히 동작하였고, 젖은 태그가 마른 이후 이전의 태그와 같은 인식률을 가지는 것을 볼 수 있었다. In this paper, the embroidery RFID tag using electro-thread, has been designed and measured. The embroidery tag antenna shaped like the Korean alphabet ‘ㅂ’ has been designed. The embroidery RFID tag d esigned with electro-thread is flexible, washable and doesn't have any problem with wearing them compared to the cooper inlay pat antenna. To confirm performance of the fabricated embroidery tag antenna, the tag antenna has been soaked into water, salty water and soapy water, and the reading ranges of different cases haven been measured. The results show that the reading range is shorter than the non-wet tag, but after dry the tag the reading range went back to normal like non-wet embroidery tag.
