Spontaneous paralysis of the anterior interosseous branch of median nerve is characterized by a sudden loss of power followed by paralysis of the muscles innervated by the nerve the flexor pollicis longus, the flexor digitorum profundus to the index finger and the pronator quadratus. Usually it i will be accompanied or proceded by pain in the region of the elbow of the affected side. Paralysis of the pronator quadratus is not easy to detect but the limitation of pronation may be j easily formd due to the weakness of the affected forearm in the position of the arm held to the side of the trunk and elbows flexed to a right angle. The sensory changes are not usually found. A case of Kiloh-Nevin syndrome developed in left hand was reported, who was 22 year old male, with complaining of swelling, tenderness and pain of left arm with chest pain due to a simple fracture of the left humeral shaft which was treated by open reduction and fixed intramedullary Rush-pin through antero-lateral approach (Henry approach). Post-operative 3 weeks, the physiotherapy was done, and at that time the patient complained weakness of pronation of the left forearm. The physical examination revealed weakness of the flexor digitorum sublimus and profundus of the index and middle finger without sensory change. After seven to eight months of active and passive exercises, the case was completely recovered. The following are important points through our experience. 1) The Flexor power of the index finger was an important criteria to be examined for Kiloh-Nevin syndrome. 2) Anterior interosseous nerve paralysis was more likely to occur with fracture of the humerus that was markedly displaced. 3) The injury was did not implicate the median nerve at the fracture site. 4) Spontaneous recovery in seven to eight months occured.
한국대학생들의 부사어구 사용과 화용론적 어조에 관한 연구

The purpose of this study is to investigate pragmatic proficiency by studying how adverbials contribute to pragmatic tone. A discourse completion test(DCT) was administered to lower and higher proficiency Korean college learners enrolled in regular English courses in four universities. The results show that there are similarities between lower and higher groups from the perspective of the range and frequency of adverbials. However, the difference between the two groups is that they use different adverbials to represent pragmatic tone. Compared with the lower proficiency group, the higher proficiency learners use wider range of adverbials with wider range of tones. The findings indicate that pragmatic proficiency should be studied not only in pragmatic strategies but also in the skillful use of adverbials to convey the messages. Teachers should consider that the appropriate use of adverbs contributes the learners' utterance as well as writing skills.
정태안정도 해석에 미치는 발전기 교차자화 포화특성의 영향
김덕영 한국조명전기설비학회 1998 조명·전기설비학회논문지 Vol.12 No.2
본 논문에서는 발전기의 특성을 보다 정확히 해석하기 위해 발전기의 상세모델에 동일축 전류성분에 의한 포화특성과 교차자화에 의한 포화특성을 고려한 상태방정식을 발전기의 전류모델에 대하여 제시하였다. 발전기의 포화특성을 종래의 동일축성분 전류에 의한 포화특성 뿐만 아니라 교차자화 효과에 의한 포화특성까지도 고려할 수 있도록 각 경우의 자속쇄교수와 전류의 관계를 나타내는 인덕턴스 행렬의 표현식을 보였으며, 발전기를 해석하기 위한 기준 좌표계로 발전기의 d축이 q축보다 위상이 $90^{\circ}$앞서는 좌표계를 사용하여 관계식을 재정립함으로써 정태안정도 해석에 사용하던 기존의 발전기모델과 일치하도록 한였다. 사례연구를 통해서 보다 정확한 안정도 해석을 위해서는 교차자화 효과를 고려한 발전기 모델이 계통해석에 사용되어야 함을 입증하였다. This paper presents a modeling of a synchronous machine infinite bus system of which not only seperated saturation effect but also cross magnetization effect of the saturated generator is included for the more precise analysis of the system. In the process of reforming the flux linkage equations of the state equations which have generator saturation effects, the d-axis coordinated system of a generator is fixed that the d-axis proceeds the q-axis in $90^{\circ}$ to accord with the generally accepted generator model used before. The simulation results show that cross magnetization has a very important effect to the more precise eigenvalue analysis of steady state stability.bility.
