터널 통과후 인터체인지가 위치하는 구간은 터널내 표지판의 설치가 불가능하며 터널 직후 시거가 불충분한 특성이 있다. 본 연구는 터널 통과후 인터체인지가 근접하여 위치하는 구간의 차량 운행특성을 분석하여, 교통안전을 고려한 적정 이격거리를 제시하였다. 터널과 인터체인지 이격구간의 차량 운행특성 지표는 사고율을 기준으로 하였으며, 총 3개 노선, 7개 지점에 대하여 1992년부터 1997년까지 교통사고자료, 교통량자료가 사용되었다. 터널과 인터체인지가 근접하여 위치하는 구간의 사고율과 이격거리와의 관계는 음의 로그함수형태, 즉 터널과 인터체인지의 이격거리가 짧을수록 높은 사고율을 보이며 이격거리가 길어지면 사고율이 줄어드는 형태를 보이는 것으로 분석되었다. 설계속도 100km/h, 편도 2차로인 고속도로에서 교통 안전을 고려시 터널과 인터체인지 적정 이격거리는 2.6km로 산출되었다. Where an interchange is located just after a tunnel not only it is impossible to install the traffic signs in tunnel sections but also sufficient sight distance to identify the interchange can't be provided. The objective of this study is to suggest the safety based spacing between tunnel and interchange. For this study accident rate was used as an index representing characteristics for vehicle operation to suggest the appropriate spacing. Traffic volume and the number of accidents on freeway from 1992 to 1997 were analyzed. The relationship between accident rate and spacing represents negative logarithm function such that shorter spacing increases accident rate. An appropriate safety based spacing between tunnel and interchange for four lane freeway with the design speed of 100kph was found as 2.6km.

Although Sjogren's syndrome is a common disease presenting overlap syndrome, the association with scleroderma is extremly rare. Clinical and immunopathological studies have been presented in 48 year-old female patient who had suffered from dry eye, dry mouth and Raynaud's phenomenon in recent 2 years. The diagnosis of Sjogren's syndrome and scleroderma has been made on the basis of clinical symptom, laboratory findings and biopsy of lower lip and dorsal skin of the finger. The clinical symptoms of Sjogren's syndrome and Raynaud's phenomenon were significantly responded after administration of systemic steroid, calcium channel blocker and local artificial tear.

Femoral stem fracture is an uncommon reason for the failure of total hip arthroplasty, with only 16 cases of fully coated stem fractures reported to date. Here we report a case in which a fully coated primary femoral stem fracture occurred after conversion to total hip arthroplasty for the non-union of an intertrochanteric fracture of the femur. Metallurgic evaluation of the etiology and mechanism revealed that the fracture was initiated by fatiguerelated failure and completed by ductile failure on the posterior side of the fracture. Considering the recent trend of treating an intertrochanteric fracture with hip arthroplasty, possible stem failure should be considered, since most patients will have at least one of the known risk factors for stem fracture.

As the osteoporotic patient population grows, various periprosthetic fractures that cannot be classified appropriately can occur around the femur after hip arthroplasty. We experienced two cases of periprosthetic insufficiency fractures at subtrochanteric area of the femurs around radiographically loose cemented femoral stems. The ages of the patients were 75 years and 83 years. Both patients could not recall any history of trauma before the onset of pain. Both were treated non-operatively. Both healed uneventfully and did not recur after two years of follow up. When the osteoporotic patient with cemented stem showed sudden hip or thigh pain without a history of trauma, great attention should be focused to find this lesion.

Paleomagnetic study is carried out to investigate the possibility of remagnetization by dikes in the Cretaceous Gyeongsang Basin. We selected a site for a contact test as a preliminary study, and collected 41 core samples (7 from andesitic dike, 17 from sedimentary rock on the left side of dike and 17 from sedimentary rock on the right side). Magnetite was responsible for the remagnetization based on microscopic observation and demagnetization analysis. Although the increasement of magnetic susceptibility appears on both sides about 100 cm from the dike, the increment of NRM intensity was obtained from the specimens on the left side only. This is interpreted that the size of magnetite newly formed is dominated by superparamagnetic grains in the right side, but by larger than single-domain grains in the left. Reversed polarity component remagnetized by intrusion of dike was also found only for core samples from 116 cm left side of dike but abscent from right side indicating the remagnetization by the dike depends on the geometric shape and width of the dike, which is supported by field observations. The content of epidote is well correlated with remagnetization, and indicates the hydrothermal alteration/metameorphism was activated by the intrusion. We concluded that the above evidences in this study further support thermally-activated chemical origin of the remagnetization with meager contribution of contact metamorphism, and that any significant evidence of regional-scaled remagnetization was not found in the study area.
