When thermal conductivity of rock is measured with PEDB (Portable Electronic Divided Bar) in a laboratory, it can be greatly influenced by the change of room temperature. Therefore, measuring the thermal conductivity in a thermo-hygrostat is necessary, where it can remain in its constant temperature and humidity condition. In this study, a system for thermal conductivity measurement in a thermo-hygrostat has been set up and the thermal conductivities for the 45 samples collected from GH3 and GH4 boreholes in Ulleung Island have been measured both in dry and saturated conditions. Also, the correlations between those thermal conductivities, density, and effective porosity have been discussed. As a result of correlation analysis among the thermal conductivity, density, and effective porosity, it showed higher correlation with dry samples than saturated samples. Especially, thermal conductivity ratio between saturated and dry conditions shows very high correlation (R2 = 0.90) with effective porosity. 상온 환경에서 PEDB (Portable Electronic Divided Bar) 시스템을 이용하여 암석의 열전도도를 측정할 경우 실내온도 변화에 영향을 받는다. 따라서 온도와 습도를 일정하게 조절할 수 있는 항온항습기 내에서 열전도도를 측정하면상온 환경에서 측정할 때의 단점을 보완할 수 있다. 이 연구에서는 항온항습 상태에서 열전도도를 측정할 수 있는 시스템을 구축하여, 울릉도의 GH3, GH4 시추공에서 채취된 45개 시편에 대해 항온항습기 내에서 건조 및 수포화 열전도도를 측정하고 그 특성을 살펴보았다. 또한, 16개 시편에 대해 밀도 및 유효공극률을 측정하여 열전도도와의 상관관계를 분석하였다. 열전도도와 유효공극률 및 밀도의 상관성 분석결과, 수포화 시료보다는 건조시료에서 보다 높은 상관성을 보였으며, 특히 “수포화/건조 열전도도비”는 유효공극률과 매우 높은 상관성(R2 = 0.90)을 보였다.

Fifty two infants and young children hospitalized in the pediatric department of Hanyang Uni- versity Hospital with acute gastroenteritis from Febtuary through April 1982 were examined for the evidence of infection with rotavirus by electron microscopic technique and enzyme-linked immuno- .sorbent assay (ELISA). Of 52 patients examined, rotaviruses were deteeted in stools of 1l patieats (21Fo) by EM technique , and 16 patients (3IY) by ELISA. But there was no significant statistical difference between the two methods (Z= l. 2$lt;2). During the study period, rotaviruses were detected in stools of 6(38Fo) of 16 patients in February, 10(30Yo) of 33 patients in 54arch, and none of 3 patients in April, The age of the 16 patients who shed the rotaviruses in their stools ranged from 3 months to 6 years, and 12 patients (75g) were between 6 and 24 months. Our study suggests that the rotaviral gastroenteritis of infants and young ehildren in Korea might have similar frequency, seasonal variation, and age distribution with other countries in temperate zone.

Scaphoid fracture is the most common carpal bone fracture and at least 5% of acute fractures of the scaphoid fail to unite after conservative treatment. The failure have been attributed to delay in beginning treatment, inadequate immobilization, displacement of fragments, instability due to ligamentous injury, and inadequate blood supply of the proximal fragment, Previously, some authors reported several kinds of treatment mordality for nonunion of scaphoid. Of all the techniques that have been introduced, we have used open reduction and internal fixation(O/R & I/F) with autogenous iliac bone graft(AIBG). We reviewed the 10 cases of patients who underwent 0/R & I/F with K-wire or Herbert screw and AIBG from Jan 1985 to Aug 1994. The results were as follow: 1.Among 10 cases, 9 cases were male and 1 case was female, and all cases were right hand, and most common age group was twenties(70%). 2. The most common cause of injury was falling with outstretched hand in 8 cases. 3.In the previous treatment, 8 cases had non spcific treatment and 2 cases had cast immobilization. 4.In the operation method, open reduction and internal fixation (0/R & I/F) with K-wire combined with autogenous iliac bone graft(AIBG) for S cases, and 0/R & I/F with Herbert screw combined with AIBG for 1 case and 0/R & I/F with Herbert screw without bone graft for 1 case. 5.After operation, average duration of cast imobilization was 2.8 months(2.5months-3months). 6.All patients had a bony union with average duration 6.2 months(3months-10months).
