Purpose: The purpose of this study is to investigate the effects of 8 weeks of neuromuscular training on muscle strength, power, and dynamic posture control in freestyle skiers. Method: The subjects of this study were 14 male freestyle skiers. They were classified into exercise groups (n=7) and control groups (n=7). The exercise group performed neuromuscular training 1 hour three times a week for 8 weeks and conducted muscle strength, power and dynamic posture control tests before and after. The data process of this study was calculated as mean (M) or percentage and standard deviation (SD) of all measured values, used a repeated Two-way ANOVA test and paired t-test. The significant level of hypothesis verification was set up as α=.05. Result: The results of the study showed a significant increase in muscle strength and sargent jump. The dynamic posture control test showed a significant increase in left and right lateral stretching. Conclusion: In conclusion, the eight-week neuromuscular training will help athletic performance and prevent injury by improving the muscle strength, power and dynamic posture control ability in freestyle skiers.

저자들은 광범위 수술적 절제가 불가능한 상악동 부위에 생긴 골육종 환자에 대해 항암화학요법과 방사선 요법을 시행하여 장기 생존을 보인 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Maxillary osteosarcoma is an aggressive disease with a high mortality rate. Extensive surgical resection is accepted as the standard treatment for the disease. The beneficial role of chemotherapy and radiotherapy in the treatment of the disorders is uncertain. We experienced a case of an osteosarcoma of the maxillary sinus. Paranasal sinus computed tomography showed a huge solid mass lesion at the left maxillary sinus walls. An endoscopic biopsy showed an osteoblastic type osteosarcoma. In this case, radical surgery was impossible, and the patient was treated with chemotherapy and radiotherapy. This regimen involved four cycles of chemotherapy, cisplatin, 100 mg/m2 intravenously on the first day of weeks 1, 4, 7, and 10, and doxorubicin, 25 mg/m2 per day on the first 3 days of weeks 1, 4. 7. and 10, followed by external beam radiotherapy with a total dose of 6,600 cGy. We report here a case of an inoperable osteosarcoma of the maxilla with long-term survival after chemotherapy and radiotherapy with an accompanying review of the literature.

Objective : The purpose of this study was to investigate the strategies used to cope with stress and the cognitive characteristics of somatic symptom perception in patients with panic disorder. Methods : A total of 101 patients who met the DSM-IV criteria for panic disorder and 60 normal controls were recruited for participation in this study. We evaluated the subjects using The Way of Stress Coping Questionnaire (SCQ), Somato-Sensory Amplification Scale (SSAS), Symptom Interpretation Questionnaire (SIQ), and the Panic Disorder Severity Scale (PDSS). We analyzed the data using an independent t-test and Pearson correlation analysis (p<0.05). Results : The patients who used emotionally focused coping strategies scored significantly lower on the SCQ. The patients with panic disorder showed greater amplification of body sensations in the SSAS, a significantly higher score on the physical interpretation subset of the SIQ, and a lower score on the environmental interpretation subset of the SIQ than the normal controls. The PDSS scores were positively correlated with the SSAS score and physical interpretation score on the SIQ. Conclusion : These results show that patients with panic disorder have poor emotionally focused strategies for coping with stress, greater amplification of body sensations, and a tendency towards a physical interpretation of somatic symptoms.

패턴 인식 분야는 지난 수 십년 간 많은 연구와 실험이 계속되어 왔으며, 상당한 발전이 있었다. 최근에 신경망 분야가 급속히 발전하면서 신경망을 이용한 패턴 인식 방법에 대한 연구가 폭 넓게 진행되고 있다. 본 논문에서는 패턴의 분류 문제에 자주 사용되는 신경망의 하나인 Radial Basis Function(RBF)에서 더욱 발전된 Elliptical Basis Function을 이용하여 필기체 숫자를 오프라인 상태에서 인식하는 시스템을 연구한다. 또한 인식 대상인 필기체 숫자 패턴은 그 크기나 형태가 다양할 뿐만 아니라 회전되어 있을 수 있으므로, 이러한 상황하에서도 인식이 가능하도록 하기 위해 전처리 단계에서 LAT 기반 비선형 정형화 방법을 사용하였다. 제안된 신경망은 임의의 축을 가지는 타원 기반 클러스터화 방법을 사용하여 기존의 원 기반 클러스터화 방법을 사용한 신경망보다 입력 데이터의 분포 상황에 민감하게 반응하여 대폭 감소된 개수의 클러스터를 얻음을 실험 결과를 통해 알 수 있었다.

54 unipolar pmstheses and 61 bipolar prostheses with same femoral stem were examined clinically and radiologically at an average of 34 months postoperatively. The average age of the patients in unipolar group was 74 years and 71 years in bipolar group. All prostheses had been inserted due to femoral neck fractures. There were two cases of dislocations, two cases of acetabular erosion in unipolar group and bipolar group, respectively. Dislocated prosthetic head was reduced with closed method in unipolar group, meanwhile open reduction was required in bipolar group. One case of early failure was found in cemented bipolar arthroplasty at post-op 2 years follow-up. Functionally, the results were excellent and good in 70.4% of unipolar group and in 73.8% of bipolar group. There was no significant difference between unipolar and bipolar arthoplasty.

저자들은 65세 여자 환자가 직장 중압감을 주소로 내원하여 복부 단층 촬영상에서 난소에 종괴가 확인되어 시행한 조직 검사상 소세포암으로 판명되었으며, 4차례의 cisplatin+etoposide 복합항암화학 요법 시행 후 완전 관해된 뒤 약 5년간 재발의 증거가 없는 경과가 매우 양호한 진행 병기의 원발성 난소 소세포암 1예를 경험하였기에 이에 문헌고찰과 함께 보고하는 바이다. Ovarian small cell carcinoma is a rare type of ovarian carcinoma with a poor prognosis.The hypercalcemic type is a tumor of unknown histogenesis, and small cell carcinoma of the pulmonary type may be a component of a typical ovarian surface epithelial-stromal tumor. We experienced a case of primary ovarian small cell carcinoma and lung metastasis. The patient was a 65-year old woman who complained of rectal heaviness. The chest x-ray and chest CT scan revealed multiple pulmonary metastases. Abdominal MRI showed a well defined heterogenous solid mass with central necrosis arising from the right ovary and hydronephrosis of the right kidney. Biopsy of the ovarian mass showed small cell carcinoma of the pulmonary type. After 4 cycles of cisplatin (80 mg/m2, on day 1, iv), etoposide (100 mg/m2, on day 1 to 3, iv), the patient achieved a complete response. The follow up chest CT scan 5 years after treatment revealed no evidence of disease. We report here in a case of primary small cell carcinoma of the ovary with lung metastasis and we include a review of the literature. (Korean J Med 72:563-567, 2007)
