Causaliga is a syndrome of sustained burning pain, allodynia and hyperpathia after a trau- matic nerve lesion, often combined with vasomotor and sudomotor dysfunction and later trophic changes. Various treatments of causalgia contain sympathetic blockade, sympathectomy, transcuta- neous electrical nerve stimulation, physical therapy, cryotherapy and psychotherapy. Repeated stellate ganglion blocks with 6ml of 0.25 bupivacaine provided good results for 2 patients. We recommand sympathetic blocks for treatment of causalgia.

High carbon steel is used for rails due to the excellent wear resistance, however the welding of high carbon steel is more difficult than that of mild steel owing to the high hardenability and sensitivity to cracking at the weldment. In this study, the impact toughness and cracking behavior of a rail weldment were evaluated as function of preheating temperatures. Impact toughness were more excellent in the specimen welded with preheating temperature above 250℃ than that below 100℃, and cracks were not detected in the specimen welded with preheating temperature above 250℃.

Feasibility study of the application of a developed annealed austenitic stainless steel at cryogenic temperature has been performed for membrane tank of LNG ship. Chemical properties of developed stainless steel are compared with a domestic commercial stainless steel and a foreign stainless steel which are used for LNG ships. Tensile properties at cryogenic temperature and fatigue strength at room temperature are measured for but and lap joints which are TIG welded specimens. Developed stainless steel having a small amount of titanium component shows the finest grain size in the HAZ, compared with the other stainless steel studied. Tensile strength, elongation and fatigue strength of the developed stainless steel are equal to those of the foreign stainless steel studied and are higher than the domestic commercial stainless steel studied.
