  • The Dongbok lake water before and after alum coagulation and activated carbon adsorption were analyzed in terms of organic contents, molecular weight distributuin (MWD), and UV-absorbance. Dissolved organic compounds in the Dongbok lake were fractionated into three molecular size classes by gel permeation chromatography. The fractionation was reasonably successful in isolating compounds with The bulk of the dissolved carbon was present in compounds of molecular weight in the range of 3,000~10,000. Alum coagulation preferentially treated molecules of high molecular weight, which has molecules larger than 10,000. The dissolved organic carbon (DOC) removal after activated carbon adsorption was high in the Fraction B , IR . The $A_{260}$/DOC ratio after alum and activated carbon treatment the Fraction II, III. This results suggest that the organics remaining after each treatment has a trihalomethane formation potential

  • BSCCO superconducting thin films have been fabricated by co-deposition using IBS(Ion Beam Sputtering) method. Despite setting the composition of thin film Bi2212 or Bi2223, in both cases, Bi2201, Bi2212 and Bi2223 phase were appeared. It was confirmed the obtained field of stabilizing phase was represented in the diagonal direction of the right below end in the Arrhenius plot of temperature of the substrate and PO$_3$, and it was distributed in the rezone. The XRD peak of the generated film continuously changed according to the substrate temperature.

  • 올해(2004년) 연말로 예정된 남북철도 연결이 동복아 지역의 물적교류에 미칠 영향에 관한 연구는 TSR, TCR, TMGR, TMR에 관한 연구와 함께 국내에 이미 상당한 수준 축적되었지만 물적교류와 함께 동북아 교류협력에 또 한 축을 이루고 있는 인적교류 즉 여객수송에 관한 연구는 거의 없는 실정이다. 본 연구에서는 인구가 조밀하고 경제성장 속도가 빠른 서울$\leftrightarrow$북경 축에 국제 여객열차를 운행 할 경우를 가정하여 기존의 항공${\cdot}$해운에서 철도로의 수요 전환량을 실제 설문조사를 통하여 구하고 이를 수송할 열차 운행계획을 세운다. 나아가 국제 여객열차 운영자의 입장에서 예상수입 및 비용을 현실성 있게 계산하고 수익성 여부도 검토한다.

  • This study investigates the differences in the purchasing behavior of infant & children's wear with the features of children and consumers. This study conducted a survey on female buyers of infant & children's wear. 558 questionnaires were analyzed by using SPSS 18.0 statistic program with factor analysis, Cronbach's ${\alpha}$, cluster analysis, ANOVA, and paired t-test. The results are as follows: 1. The buyer's value was identified with 3 factors: mental achievement value, social achievement value, and pleasure value. Three types of group by values were identified: group seeking mental social achievement, group seeking social achievement, and group seeking pleasure. 2. Fashion and conformity, pleasure pursuit, and reasonable price pursuit orientations showed significant differences among the value groups. 3. A significant difference was found in the imitation of wearing role models according to sibling relationships.

  • The purpose of this study is to investigate relation between kucha and Korea by comparing costume. The results are as follows. First, During 508th century, wall paintings of Kizil and Kuizilkargha showed traditional costume such as cutting hair , lapel coller and fitting sleeve coat, pants, boots , belts and knife. Kumtura were also in 6 th, but under the influence of China and Hoehol (회골) after 7th. Second, Men and women cutting hair except king, they put on cone shaped hat and Kun (건), clothing were made of felt and kun(면). Third, it was influenced by Iran that cutting hair in Silla (신라) and Kucha. In Silla , round neckline and V neckline were existed except lapel collar. Jeweled knife of Silla and Kuncha , pattern of Kumdonglee(금동복) showed cultural exchange of centural Asia and Korea along the Silk Rood. It is conscious that Silla preferred centural asia of texture and jewels by prohibition of costume.

  • Due to increasing demands for environment-friendly railway system, bronze wires with cadmium, which is a potential environmental hazard, have been no longer permitted as messenger wire for electric railway system. One of materials being considered as the replacements is copper-clad steel conductor(CCSC), which is currently used as contact wire for high speed operation in the Japanese shinkansen. However, there have been few studies for the application as messenger wire by the CCSC. This study deals with requirements and performances of the messenger wire stranded by the CCSC, especially for high speed electric railway. And the tentative evaluation items and methods to be specified as the Korean railway standard(KRS) are proposed.

  • 환경동위원소 기법을 쓰레기 매립장의 침출수 및 주변 지하수에 적용해본 결과 미생물의 활동에 의한 유기물의 분해과정에 대한 정보를 얻을 수 있었다. 특히 유기물 분해로 생성된 이산화탄소는 일차적으로 침출수의 알칼리도를 높이고 이차적으로 일어나는 이산화탄소의 환원작용에 의하여 메탄가스가 형성되었다. 이러한 과정에서 침출수에 잔류하는 용존무기탄소(DIC)의 탄소 동위원소 조성이 크게 부화되었으며, 아울러 생성된 메탄과의 수소동위원소 교환반응에 의하여 물의 수소 동위원소 조성이 크게 부화되는 특징이 국내에서 처음 관찰되었다.
