목적 : 경피적 겸자 정복 및 골수강내 금속판 고정술을 이용한 쇄골 간부 골절의 치료에 대해 유용성을 규명해 보고자 하였다. 대상 및 방법 : 2002년 1월부터 2003년 7월까지 본원에서 쇄골 간부 골절 환자 중 신경 및 혈관 손상이 없었고, 골절의 분쇄상이 비교적 적었던 총 16례를 대상으로 겸자를 이용한 경피적 정복 후에 골수강에 금속판을 삽입하여 고정하였다. 술 후 유합 정도 및 결과를 임상적, 방사선학적으로 분석하였다. 결과 : 방사선학적으로 골유합을 보인 경우가 총 15례였으며, 술 후 평균 9.1주에 유합 소견을 관찰하였다, 임상적으로 강 등의 기준에 따라 구분한 결과, 우수 이상이 14례로 나타났다. 1례에서 1주 만에 K-강선의 내측전위로 골절부위가 재전위되어 관혈적 정복 및 금속판 내 고정을 시행한 이외에 다른 주요 합병증은 없었다. 결론 : 저자들의 방법은 수술시간이 짧고 간단하며, 연부조직의 추가적 손상이 적어 골유합율이 높고, 수술 반흔을 남기지 않아 수술적 적응을 신중히 고려한다면 쇄골 간부 골절의 치료법의 하나로 유용할 것으로 사료된다. Purpose: To investigate the utility of surgical treatment of clavicle shan fracture using a percutaneous towel clip reduction and intramedullary fixation. Materials and Methods : This study was conducted for total 16 case of patients who had no neurovascular injury and a few comminuted bone fragment among patients with clavicle shaft fracture from January 2002 to July 2003. The method of operation was percutaneous towel clip reduction and intramedullary fixation. The clinical and radiological results were evaluated. Results : Radiologically, 15 cases showed bone unions and the avenge time was 9.1 weeks. According to Kang's criteria clinically, there were 14 cases which were more than an excellence. One case substituted open reduction and nailing fixation due to a medial migration of K-wire and re-displacement of fracture even in 1 week. However, there wasn't any other major complication. Conclusion : Due to its having no additional injury to soft tissues, no scar formations, and its short operation time, percutaneous towel clip reduction and intramedullary fixation will be very useful as one of the treatments of clavicular shaft fracture if it follows correct surgical indications.

The construction and usage of digital library are rapidly increasing all over the world. This paper introduces the concept of digital library and describes the present state of national library, private library, and university library in Korea. Additionally the library of Chonbuk national university is presented in detail. Finally we discuss how digital library can be used in the educational field.

Korea has the ground which freezes in winter and melts in warmer seasons by turns. Therefore, in designing civil-structures or buildings on such ground, the depth of seasonal frost penetration must be considered. In this paper, approximate contours of the maximum depth of frost penetration in Korea is presented. The National Construction Research Institute of Korea has measured the depth of the frozen ground covering all the area of South Korea during the ten years ranging through 1980. The measurement were made for the frozen ground at random but intended for the most frost-susceptible soils. The contour of the maximum depth of the frost penetration is drawn on a map with data collected during the ten years. It is known that the maximum depth of the frost penetration is related to freeze index values. An empirical formula expressing the relation is suggested, in which the depth is proportional to the one-fifth power of the air freezing index values.

This study was conducted to find an optimal combination rate of castor meal for the good qualitative compost and to estimate the humification grade by physico-chemical characterization and phyto-toxicity test during composting of the mixture with cow manure and castor meal. The material ratios of the compost which was mixed with cow manure(C), castor meal(C), and saw dust(S) were 5 : 1 : 4(CCS-1), 5 : 2.5 : 2.5(CCS-2) and 5 : 4 : 1(CCS-3) by volume to volume, and they were decomposed for 60 days. In the result, the changes of temperature in all treatments during composting radically increased more than 63.6℃ at the incipient stage, and gradually decreased around 42℃. At the 60 days after the treatment, pH was slowly increased from 7.0 to 8.0, and the C/N ratio was 12.3∼13.8 at the final composting stage. The low C/N ratio value was caused by the castor meal with high nitrogen level(T-N 5.7%). G.I.(germination index) showed in the range of 77.5 to 82.6 in all treatments. Among all treatments CCS-1 was appeared to be the best condition for composting. Therefore, the combination rate of castor meal which was used for compost humification improvement could be recommended 10% to manufacture the good qualitative cow manure compost.

One of the recent prominent features of Korean Middle and High school students is the lack of emotional stability. This is partly due to the current educational system which is mainly focused on the entrance examination for Colleges or Universities. So this paper emphasizes the importance of Korean youth's emotional aspects and presents a courseware program which can be effectively utilized on the actual education fields by students and teachers. Additionally it provides various knowledges for growing the plants, biological structures of several parts of plants and so on. We believe that the program contributes significantly to Korean educations with respect to the cultivation of Korean youth's emotions.
