목적: 위암의 근치 절제술에서 광범위 림프절 절제는 중요한 의미를 가지며 전이 림프절의 수가 종양의 침윤 정도와 함께 병기 결정의 기준이 되고 있다. 이에 저자들은 근치 절제술을 시행 받은 위암 환자에서 절제 림프절 수가 생존율에 미치는 영향을 분석하고 종양의 각 병기에 따라서 생존율 및 병기결정에 영향을 미치는 절제 림프절수의 최소 기준값을 구하고자 하였다. 대상 및 방법: 1992년부터 2002년까지 고려대학교병원에서 근치적 위절제술을 시행 받고 5년 이상 추적 관찰이 가능하였던 949명의 환자들을 대상으로 하였다. 조직검사결과에 따른 종양 침윤 정도에 따라 환자군을 분류하여 절제 림프절의 수를 조사하였다. 절제 림프절 수의 최소 기준값은 생존율에 유의한 차이를 보이는 최소값으로 정하였다. 결과: 종양의 크기, 위치, 림프절 병기, 전이 림프절의 수 및 절제 림프절의 수는 종양의 병기에 따라 유의한 차이를 보였다. Cox 비례위험모형을 통한 분석 결과 절제 림프절 수의 최소 기준값은 전체 환자에서는 14개였으며 각 병기별로 pT1군에서 15개, pT2군에서 28개, pT3군에서 37개의 값을 보였고 기준값 이상으로 절제된 경우 생존율이 유의하게 높았다. 결론: 근치적 위절제술을 받은 환자에서 기준값 이상의 림프절 절제가 생존을 향상시킬 수 있으며 이를 위해 외과의가 근치적 위절제술 시 기준값 이상의 림프절 절제술을 위해 노력해야 하며 병리의는 절제된 조직의 림프절 개수의 정확한 결과를 보고 하기 위해 더욱 노력해야 할 것이다. Purpose: The objectives of this study were to investigate the impact of the number of resected lymph nodes on the survival of gastric cancer patients who underwent curative resection, and to evaluate the cut-off values that can have an influence on survival on the tumor stage-stratified analysis. Materials and Methods: The subjects were 949 gastric cancer patients who underwent curative resection at Korea University Medical Center from 1992 to 2002. They were classified according to the depth of tumor invasion, and the influence of the number of resected lymph nodes on survival was investigated. The cut-off value for the number of resected lymph nodes was determined as the smallest value that showed a significant survival difference. Results: The tumor size, location, lymph node stage, the number of metastatic lymph nodes and the number of resected lymph nodes were significantly different according to the tumor stage. The average number of resected lymph nodes was about 39, and it showed linear correlation with the number of metastatic lymph nodes. On the Cox proportional hazard model, the cut-off values of the number of resected lymph nodes, as corrected by the number of metastatic lymph nodes, was 14 for all the patients, 15 for the pT1 patients, 28 for the pT2 patients and 37 for the pT3 patients, respectively. Conclusion: Retrieving a number of lymph nodes that is more than the cut-off value could improve the survival of gastric cancer patients. Surgeons should also make efforts to perform an exact and thorough D2 lymph node dissection. Therefore, we urge surgeons to perform D2 dissection and pathologists should examine an certain exact number of lymph nodes.

본 논문에서는 Orthogonal Frequency Division Multiple Access/Time Division Duplex 시스템에서 한정된 하향링크 무선 자원을 효율적으로 이용하고, 시스템 성능을 높이는 스케줄링 기법을 제안하였다. 시계열 예측 알고리즘을 이용하여 향후 변화될 기지국과 단말들 사이의 채널상태를 예측하고, 이 예측된 정보를 무선 자원 할당의 우선순위를 결정하는데 이용하였다. 시뮬레이션을 통해 제안하는 알고리즘의 성능을 분석하였고, 시스템 처리율과 지연시간에서 Proportional Fairness, 그리고 Maximum Carrier to Interference Ratio 알고리즘과 비교 평가하였다. In this paper, we propose a novel scheduling algorithm for downlink transmission which utilizes scarce wireless resource efficiently in an Orthogonal Frequency Division Multiple Access/Time Division Duplex system. Scheduling schemes which exploit channel information between a Base Station and terminals have been proposed recently for improved performance. Time series analysis is used to estimate the channel state of mobile terminals. The predicted information is then used for prioritized scheduling of downlink transmissions for improved throughput, delay and jitter performance. Through simulation, we show that the total throughput and mean delay of the proposed scheduling algorithm are improved compared with those of the Proportional Fairness and Maximum Carrier to Interference Ratio schemes.

Objectives : The aim of the present study is to report a 38-year-old patient with `top of basilar(TOB)` syndrome who shows paralysis of limbs, diplopia, facial numbness, neck weakness by vertebral artery occlusion. Methods : We treated the patient by acupuncture, herbal medication, physical therapy, rehabilitative therapy such as eye exercise. We used evaluation scale including Visual Analog Scale(VAS), National Institutes of Health Stroke Scale(NIHSS), Modified Barthel Index(MBI), Manual Muscle Testing(MMT). Results and Conclusions : Analysis of this one patient indicated that oriental medical rehabilitative therapy is useful to treat the TOB syndrome. The symptoms were improved rapidly. After treatment, the patient was able to walk and diplopia was improved. MBI score changed from 20 to 95, for NIHSS from 13 to 2. VAS and MMT were also numerically improved.

Objectives : This study was performed to evaluate the effect of Taping Therapy with oriental medical treatment in facial nerve palsy. Methods : This clinical study was carried out 7 cases of facial nerve palsy patients which had been admitted in Dong-Shin university oriental hospital from September, 2004 to November, 2004. In this study the patients were treated by Taping Therapy. Other treatments were acupunture, herbal medication, rehabilitative therapy. H-B scale(House-Brackmann facial nerve grading system) was measured from admission to discharge. Results : In the results, the symptoms were improved gradually. 1. The average of H-B scale was increased from 2.57 to 6.14. 2. Several patients were treated by oriental medical treatments without western medication, but there was no significant difference between the group treated by western medication and not. 3. The treatment period was between 5 weeks from 3 weeks. The treatment period is more shortened compared to the existing period(12 weeks). Conclusions : In the study, The treatment of facial nerve palsy using Taping Therapy was more effective, especially H-B scale and treatment period, compared to existing.

Objectives : This study was to investigate stability of spinal curvature and MMPI(The Minnesota Multiphasic Personality Inventory) profiles in traffic accident patients. Methods : Total patients were classified into TA(traffic accident) inpatients and non-TA inpatients. We analyzed the characteristics of each group - age, sex, onset period, treatment period, angle of cervical curve and lumbar curve, lumbo-sacral angle and MMPI profiles. Results : 1. According to accidental type, mean of cervical angle is more low in TA Group. Means of lumbar angle and lumbo-sacral angle are more high in TA Group. But it was no significant difference. 2. According to accidental type, L, Hs, Pa profiles were high scores in TA Group. But it was no significant difference. 3. After multiple regression analysis in total patients, Accidental type was independently related with D profiles. Conclusions : On this study, there was no significantly difference in stability of spinal curvature according to accidental type. But, in multiple regression analysis on MMPI profiles, TA patient group was significantly related with D profiles.

Objectives : To evaluate and find out psychological characteristics of traffic accident(TA) patients who were diagnosed as sprain of C-spine and L-spine, and suffering from psychological disorder. Methods : 35 patients wrote out Minnesota Multiphasic Personality Inventory(MMPI). We divided them into four groups according to the type of TA - car to car and car to person, posttraumatic stress disorder(PTSD) and sex. We sent medical records and MMPI reports to Dept. of Oriental Neuropsychiatry Medicine and asked who were PTSD patients. Results : 1-3/3-1 profile was found by total mean of T score of each MMPI scale in all patients. 1-3 profile was found in car to car and non-PTSD group. 3-1 profile was found in car to person and PTSD group. The difference was not valid by the type of TA, PTSD and sex(p<.05) except for the clinical scale of hysteria. Conclusions : The results indicate that MMPI characteristics of TA patients were generally 1-3/3-1 profile and patients who showed 3-1 profile must be treated more carefully because they were underlying PTSD patients.
