최광순,조호근,손영호,최광규 東亞大學校 建設技術硏究所 1997 硏究論文集 Vol.21 No.2
In this paper, the relation between the local stress and the fatigue behavior at gusset plate connected with main girder and floor beam in arch bridges was obtained. The conclusion was as follows : (1) In-plane bending moment and out-of-plane bending moment are higher than other internal stress resultants. (2) When a vehicle crosses the bridges, the change of out-of-plane bending moment corresponds with the change of relative difference in displacement in the longitudinal direction between the tie-girder and stringer. (3) The change of in-plane bending moment corresponds with the change of the displacement in the transverse direction of arch-rib. (4) Fatigue crack can be initiated by in-plane bending stress that is produced by out-of-plane bending moment at the toe of gusset plate. (5) Fatigue crack can be initiated by tension stress that is produced by in-plane bending moment at the toe of gusset plate.

Background : Medical records are documents in files which consist of all diagnostic studies and medical treatments patients had received while they were hospitalized or treated as outpatients. A doctor or medical team can use medical records as a data for diagnosis, treatment, and education. In traditional eastern asian medicine, medical reports have different forms and contents. The most important thing in medical reports of traditional eastern asian medicine was how to express practitioner's medical ideas. So it has a weak point, for example, it has poor information about patient and clinical process, which make some trouble to understand it. Methods and Results : We studied medical records in Gyojubuin-yangbang, a commentary book of Chen-zi-ming's Obstetrics and Gynecology textbook done by Xue-ji in Ming dynasty, China. This book consists of 10 parts; treatment of menstruation disorders and leukorrhea, general gynecology, treatment of infertility, education for fetus, diagnosis of fetus and gravida, treatment of general and obstetrical disease in gravida, care for delivery, postpartum care and treatment, and treatment of mass and inflammation. It has 546 medical records about women's disease that commonly believed as Xue-ji's case reports. They are all review articles and made during about 23 years from A.D 1523 to 1546. Most patients of Xue-ji's case reports were common people, this fact is different from that of case reports in Chen-zi-ming's Obstetrics and Gynecology textbook. Conclusion : Xue-ji was a very famous Ob&Gy doctor who was from Suzhou Jingsu province in China. He was born in A.D 1468, died in A.D 1588. He emphasize emotional factors in pathology and to tonify spleen and kidney. We think Xue-ji's medical records are good references for us to treat psychosomatic Ob&Gy disease and chronic women's disease.
