  • Tsunamis generated by of the 1992 Flores Island Earthquake in Indonesia caused tremendous casualties and damages. This tsunami event was hindcasted via numerical tsunami models. Initial conditions were taken from fault parameters from Havard CMT (Centroid Moment Tensor) solution and additional subaqueous slump consideration at the Inner Hading Bay and Riang Krok, Leworahang coasts. The computed results showed general agreements with observations made by the International Tsunami Survey Group. Subsequently a runup model was developed to investigate catastrophic runup at southern shore of the Babi Island with fine grid resolution of 50 m. Computed results were recorded to construct rendered images for video animation. The computer-graphic aided video animation showed a remarkable reproduction of tsunami propagation and runup at southern coast of the Babi Island.

  • Purpose: Complete release of the transverse carpal ligament (TCL) is accepted as the standard treatment for carpal tunnel syndrome (CTS). However, loss of grip and pinch power are reported in some patients after complete release of the TCL. This study was designed to evaluate the effectiveness of complete versus partial carpal tunnel release by using the inching technique. Methods: Nineteen patients (a total of 27 hands) who each had a confirmed diagnosis of CTS were selected from September 2002 to February 2003. The cases were divided into three groups(mild, moderate and severe) based on preoperative electrodiagnostic studies. The patients with partial carpal tunnel syndrome were classified into the mild or moderate groups, while patients with complete carpal tunnel syndrome were classified into the moderate or severe groups. Patient oriented data (functional and symptomatic) were collected and electrophysiologic studies were undertaken preoperatively and postoperatively(on the 2nd week, 1st month, 3rd month and 6th month after surgery).Results: In this study, the mild and moderate groups showed both good functional and symptomatic results and improvements in electrophysiologic studies.Conclusion: Carpal tunnel syndrome patients classified into mild or moderate groups based on nerve conduction studies, and whose precise compression sites were pinpointed using the inching technique, can be treated by partial carpal tunnel release.

  • In order to convert the one ryang of Guizhi-tang into the modern weights and measures, herbs whose dose was expressed by number in Treatise on Feverile Disease of Zhongjing were measured actually. The results obtained are as follows. 1. Size of Jujubae fructus in Guizhi-tang is an average and if remove the seed, 12 Jujubae fructuses corresponds to 20g. These weights are the same as Belamcandae Rhizoma, Persicae Semen, Gleditsiae Fructus, Gardeniae Fructus and Armeniacae amarum Semen whose dose was expressed by number in Treatise on Feverile Disease of Zhongjing. If one ryang corresponds to 6.5g, 20g corresponds to three ryang. If one ryang corresponds to 15.6g, 20g corresponds to 1.3 ryang. When herbs were added in Guizhi-tang, the used weights were two more ryang. Almost unit of weights in Formulae of Zhongjing is the constantly multiplied. 2. Half sheng(升) of Pinelliae Rhizomae is 15 Pinelliae Rhizomas and corresponds to two and a half ryang. 14 Pinelliae Rhizomas are contained in 50 mL egg. 3.1 geun(斤), maximal amount of Gypsum Fibrosum and amount of one egg are the same weight supposing one ryang corresponds to 6.5g. 4. 2 ryang of Rhei Radix et Rhizoma is the 6.8 balls(碁子) of baduk and similar as 5-6 balls of baduk of Jisilchijasi-Tang. 5. General dose of Glycyrrhizae Radix is two ryang and 20mL, the size of thumb is 13g. 6. Half geun approaches the 3 flattened spoons. Consequently the presumption that one ryang in Guizhi-tang is 15.6g is wrong. One ryang is assumed as 6.5g.
