金成原,李舜鐸 嶺南大學校 工業技術硏究所 1997 工業技術硏究所論文集 Vol.25 No.2
In this study, it is applied for HEC-6 model which is I-dimensional bed profile change calculation model to analyze bed profile change between HyeonPung water stage gauge(No.314+250) and Taegu 5th-water supply intake dam(No.379) in the Nakdong alluvial channel. as the result of this analysis, it is found that HEC-6 model can be simulated bed profile changes in alluvial channel and by the statistical analysis of the changes, it can be also simulated long-term bed profile changes including factitious aggregate gathering in nakdong main channel. However, if it is happened large-scale constant aggregate gathering in this study channel, it is much taken placed local bed profile decline than expected. therefore, it is needed considerable decision for the large-scale aggregate gathering in this study channel. and because HEC-6 model can't simulate local scouring, it can be complemented by way of applying the 2,3-dimensional model for local scouring analysis and needed constant study in this field.

다결정 EuFeO₃의 결정구조와 자기적성질을 X선 회절과 액체질소온도에서 395 K의 온도영역에서 Mossbauer 분광방법으로 연구하였다. X선 회절무늬와 Mossbauer 스펙트럼 분석결과는 본 연구의 시료가 단일 결정상임을 보이며, 시료의 격자상수 a?, b?, c?는 5.550, 5.570와 7.731Å으로 결정하였다. 초미세자기장의 온도의존성에 spinwave 이론을 적용한 결과 넓은 온도구간에서 실험치와 잘 일치함을 보였다. The crystallographic and magnetic properties of EuFeO3 have been studied by the methods of X-ray diffraction and Mossbauer spectroscopy within the temperature ranges from liquid nitrogen temperature to 395 K. The X-ray pattern and Mossbauer spectra of the sample show that the sample is in the single crystal phase with the lattice constants a?, b?, c? determined to be 5.550, 5.570 and 7.731Å, respectively. And the spin-wave theory has been applied to the temperature dependence of the magnetic hyperfine field of the sample. The result shows that the theoretical equation is in a good agreement with the data within the wide ranges of the temperature.

西洋 喪葬禮 儀式 및 服飾에 관한 硏究 : 古代에서 近代까지
김경희,이순홍 服飾文化學會 2002 服飾文化硏究 Vol.10 No.4
Funeral culture, which came to being along with the death of human beings, has developed through many changes in the background, culture, religion and custome of the times, having variant cultures depending on each nation of ear. This study is designed to historically and systematically classify funeral rituals and costumes which have constantly changed in a special funeral culture from ancient times to modern times so as to investigate the features of each age. The researcher worked on Western funeral culture, focusing on Egypt and Rome of ancient times, Greek times, the Middle Ages, recent and modern times ages, referring to literature, precedent studies, domestic and international technical books, pictures and drawings in relation to death and funeral services. Western funeral rituals were designed for offering condolence to the dead, but also used to show off th status of the mourners and the position of the dead persons. The mourning dress were utilized to indicate mourning in accordance with the colors, materials and the ways of wearing them, serving as a vehicle for showing off one`s own status.

홍월 사과의 재배에 있어 봉지 씌우는 시기와 봉지종류에 따른 홍월반점장해 발생에 미치는 영향을 비교하기 위한 실험의 결과는 다음과 같다. 1. 흑갈색 반점인 type A 반점의 경우는 봉지 씌우는 시기가 빠를수록 반점장해의 발생율과 과실당 반점수가 적은 경향을 나타내었고 봉지 종류간에는 이중착색봉지가 신문봉지에 비해 반점발생유과 과실당 반점 수가 적은 경향을 나타내었다. 발생반점의 크기는 봉지 씌우는 시기와 봉지 종류간의 차이가 인정되지 않았다. 2. 녹색 반점인 type B 반점의 경우는 봉지 씌우는 시기가 빠를수록 반점장해의 발생율이 적은 경향을 나타내었으나 봉지종류 간의 차이는 인정되지 않았다. 과실당 반점 수는 처리간의 유의한 차이를 발견할 수 없었으며 발생반점의 크기는 작은 경향을 나타내었고 봉지종류간의 차이는 인정되지 않았다. 3. 과실품질은 처리간의 차이가 없었다. Different kinds of bags and bagging dates were tested to compare with the effects on the appearance of browing spots on the "Kogetsu" apples. The number and appearance rate of black spots(type A) were decreased by early bagging and using double color bag compare with single newspaper bag. The size of the spots was not significantly different depend on the kinds of bags and bagging dates. The appearance rate of green spots(type B) were decreased by early bagging but not affected by the kinds of bags and the size of spots were the same results depend on the kinds of bags and bagging dates as the black spots. The quality of the apple was not significantly different depend on the bagging dates.

In this study, we analyzed the effects of several process variables on the removal efficiencies of NO and SO_(2) by the dielectric barrier discharge process combined with photocatalysts. The TiO_(2) photocatalysts were coated onto the spherical-shaped glass beads as dielectric materials by the dip-coating method toe analyze the effects of photodegradation reaction on the NO and SO_(2) removal. As the voltage applied to the plasma reactor increases, or as the pulse frequency of applied voltage increases, the NO and SO_(2) removal efficiencies increase. Also an the residence time increases, or as the initial concentration of NO decreases, the NO and SO_(2) removal efficiencies increase. The higher the amount of TiO_(2) particles coated onto the glass bead is, the larger the surface area of TiO_(2) particles for the photodegradation reaction is and the NO and SO_(2) are removed more quickly by the faster photodegradation reactions.

The purpose of this study was to survey the tendency of internet addiction. For the purpose of this study was to find differences actual condition of internet used by students and the internet addiction according to related variables. The subjects of this study were 1006 students at primary, secondary school, where were located in Jeollabukdo. The collected data were analyzed by percentage, mean, standard deviation, t-test, x2, ANOVA. The instrument of this study were Cheong Tag Kim(2003)' K-scale. The result of this study are as aollows. First, High school students spent the longest time using internet among three groups. Second, The students were most engaged in surfing the internet, not for doing homework or getting necessary informations but for shopping, downloading MP3 file, playing game, comic, sports and entertainment. Third, parents' attitude toward students using the internet intervened more primary school students than others. So hight school students are more exposed on the internet usage than others. Fourth, mothers' educational attainment is more affective than fathers' toward students using the internet.
