Objectives This study was performed to evaluate the clinical effect of acupuncture on children's myopia. Methods Among the outpatients with myopia who visited to Department of Acupuncture & Moxibustion, National Medical Center from June 2000 to May 2001, we selected 50 cases that did not involve ,any other pathological condition of eyes and patient age was below 17, whose eyes including with glasses or naked examined by monoocular and biocular visual acuity test per each visit and followed up for 6 weeks. Results We investigated 29 female and 21 male patients. The most distribution of age was 12.26. First mean biocular visual acutity was $0.2{\pm}0.074$. Last mean biocular visual acuity after 6 weeks was $0.8{\pm}0.046(p<0.001). Improved cases on biocular test were 38 cases($76.00\%$). Conclusions These results suggest that the acupuncture therapy is effective treatment modality on children's myopia.

IAI의 IFC를 기반으로 강 교량을 구성하는 부재의 상세 설계 정보를 표현하기 위한 방안을 제시하였다. 이를 위해 먼저 강교 부재 상세 설계와 관련한 설계기준, 구조계산서, 상세설계도면을 분석하여 실무에서 다루어지는 설계 데이터 항목과 이들의 표현방식을 분류하였다. 설계 항목을 기존 IFC 모델로 표현 가능한 것, 추가 모델이 필요한 것으로 나누었고, 보강재, 격벽, 현장 연결부, 그리고 전단연결재를 보다 체계적으로 표현하기 위한 속성 및 위상관계를 정립하였다. 마지막으로 본 연구를 통해 제시된 데이터모델을 기반으로 설계 정보 입력을 위한 프로그램을 구현하였다. 테스트용 교량에 적용하여 물리적 STEP 파일 생성함으로써 제시한 데이터 모델의 논리성을 확인하였다. Extension of IFC data model for steel bridge members is proposed to represent detailed design information. First of all, the design data items and their representation method are classified by analyzing primary references such as design specification, structural calculation documents and shop drawings. Some of the classified items are enough to be represented by the existing IFC model. However, the need of additional model is noted to systematically represent the design information for other items such as stiffener, diaphragm, joint system, and shear connector. An inheritance relations and properties for added model are also defined. The application program based on the proposed data model is developed. In the end, by loading the application program on the AutoCAD 2002 program, end-users can input the design information of steel bridge members. The applicability and efficiency of the proposed data model and the program are verified by checking the section area, intervals, and interferences.

Objective: To observe the effect of the depolarizing stimulation in amyotrophic lateral sclerosis (ALS) mouse model on the survival and behavioral performance. Method: Transgenic male mouse model of ALS at the age of 9∼11 weeks were divided into sham control group (n=10) and stimulation group (n=9). Electrode was implanted in the motor cortex in left hemisphere. Movement thresholds (MT) were regularly checked. Half threshold of MT, unipolar, and continuous electrical stimulation (frequency, 50 Hz; pulse duration, 220μs) was delivered through implanted electrode. Behavioral tests including Rota-rod and Paw-grip endurance were checked every day. Results: Induction of symptom was delayed in 8 days in stimulation than sham control group. However, there was no significant difference in survival in both groups. Behavioral tests showed that stimulation group is significantly better than sham group in Rota-rod (11∼15 weeks) and in grip endurance (11∼14, 16 weeks). MT was always between 1.0 volt and 3.2 volt in sham group, however, MT was between 0.8 volt and 2.8 volt in stimulation group. MT was jumped up around the time of death in both groups. Conclusion: Electrical stimulation is considered to be one of possible trial methods in ALS model. However, parameters of the stimulation in the experiment should be modified for better results.
New Treatment in Facial Nerve Palsy Caused by Sagittal Split Ramus Osteotomy of Mandible

A 25-years-old woman with mandibular prognathism underwent a mandibular setback by way of mandibular sagittal split ramus osteotomy (MSSRO). After 2 days of operation, she developed difficulty of closing her right eye. The blink reflex test and motor nerve conduction study of the right orbicularis oris muscle were revealed right facial neuropathy of unknown origin and House-Brackmann facial nerve grading system (HBFNGS) grade V. For treatment, we initially prescribed oral prednisolone and nimodipine including physical therapy. The samples consisted of 11 facial nerve palsy patients caused by MSSRO and were analysed about onset of facial nerve palsy, postoperative HBFNGS, final HBFNGS, treatment method and recovery time. At 10 weeks of treatment of nimodipine, she had completely regained normal function (HBFNGS grade I) of the right facial nerve. The clinical results lead to assume a fast recovery of facial nerve function by the nimodipine medication, whereas average time of recovery is 16.32 weeks in references. Despite of the limited one patient treated, the result was very promising with respect to a faster recovery of the facial nerve function. Considering the use of nimodipine treatment for peripheral facial nerve palsy following a surgical approach with an anatomically preserved nerve can be recommended.
