  • Abnormal writing can result from a large variety of neurologic disorders of motor control. Primary writing tremor(PWT) in its pure form denotes occurrence of a disabling tremor induced by writing alone. Therefore PWT is typical task-specific tremor. PWT could be classified as either type A or type B. In a strict sense, type B PWT is not pure form of PWT because it is not task specific. We describe a case of PWT type A. A 53-year-old right handed policeman complained of a 4 year history of shaking of his right hand that interfered with writing. Tremor appeared during writing but not on adopting the hand position normally used for writing.

  • Purpose : Primary writing tremor(PWT) can be classified as either type A or type B depending on whether tremor appeared during writing or whilst writing and also on adopting the hand postures normally used for writing. Through the clinical experience author has had an impression that PWT type B may not be purely dependant on specific writing postures. The objective of this study was to clarify whether PWT type B have writing posture-specificity or not. Results : The data indicated that type B PWT is not writing posture-specific. Various pronation and supination postures could evoke tremor as well as writing postures. Furthermore most of other pronation- and supination-related tasks could evoke tremors as well as action of writing. Conclusions : The present data suggest that PWT should be limited only on the pure form of task-spesific PWT type A.

  • 3일간의 심포지움을 통하여 느낀점을 몇가지 적어보면 다음과 같다. 참서자들이 첫날부터 마지막 날까지 오전, 오후 1회의 coffee break를 제외하고는 하루 종일 강연회장에 앉아서 열심히 경청하며 노트하고, 질문하는 등 열의가 대단했다. 또한 일본인 발표자 및 질문자를 위해 동시 통역을 고용하였는데, 영어 소통능력이 부족하더라도 당당하게 일어로 질의 응답을 함으로써 정보 교류가 가능하도록 배려한 점은 앞으로 우리나라에서 이와 같은 심포지움을 개최하게 될때 검토해야 할 것 같다. 특히 통역이 여성이었는데 전력 반도체 관련 용어에 매우 정통해 있고, 사전에 논문을 검토하여 질의 응답시 전문가 이상으로 능력을 발휘하는 것을 보고 우리도 이와 같은 전문 분야별 통역의 양성이 필요하다는 것을 느꼈다.

  • A 3-dimentional finite element model for vibration analysis of steam-turbine blade groups is presented, employing the 3-dimentional incompatible brick element with 8 nodes. The skew coordinate system is introduced in the model for considering multi-axis symmetry and specialty of displacement constrain condition of blade groups. Vibration characteristics of blade groups are analyzed, and compared with experimental results.

  • Sardine oil was microencapsulated by spray drying method in wall systems containing corn syrup in combination with sodium casein or wheat protein. Analysis of microencapsulation yield of sardine oil was carried out by a modified soxhlet method which could reduce the extraction time of surface oil. Microencapsulation yield of sardine oil was ranged from 65.3 to 93.5 % depending on the sodium casein content.
