Actinomycosis is a chronic suppurative infection, whitch infiltrates mucosa-associated tissues. Thoracic, pelvic and cervicofacial infections of actinomyces are not uncommon, but endobronchial actinomycosis is rarely reported. We report a case of a 29 year old man who presented with a recurrent pneumonia and chronic cough. Fiberoptic bronchoscopy revealed occlusion of the right. lower medio-basal segment bronchus with exophytic endobronchial mass. The diagnosis was confirmed histologically by demonstration of sulfur granules in the bronchoscopic biopsy of the mass. Intravenous administration of amoxacillin and clindamycin followed by oral amoxacillin and clindamycin therapy resulted in complete recovery.

주파수 도약 대역 확산 통신 방식에서 기존의 동기 시스템은 VCO의 비선형 특성, 루프의 온도보상문제, 소형화. 경량화 문제 등으로 시스템 구현에 많은 어려움을 겪고 있었다. 본 연구에서는 정합필터(matched filter)를 이용한 초기동기와 ADPLL(All Digital Phase Locked Loop)을 이용한 동기 추적 방식의 동기 시스템을 구현하였고, 초기동기시간 약 600μS, 동기추적에 약46mS의 시간을 얻어 전체 동기 시스템은 약 65mS이내를 얻었다. 일반적으로 동기시간이 100mS 이내에 이루어지면 완전한 동기를 이룬것으로 보며, 따라서 구현된 동기 시스템이 매우 안정되고 정확한 동기를 이루고 있음을 알 수 있었다. In the frequency hopping spread spectrum communication, the conventional synchronization systems have many problems in their implementation. It is nonlinear characteristics of VCO, temperature compensation of loop and implementing compactly. In this paper, we implemented the synchronization system which consists of the ACQUISITION by matched filter and the TRACKING by ADPLL(All Digital PLL). In this synchronization system, acquisition time and tracking time were about 600㎲, 64ms respectively, so that total synchronization time could be within 65ms. Generally, as synchronization time is within 100ms we can regard it as complete synchronization. therefore, we could prove that the implemented synronization system has a stable and accurate synchronization.

목 적 : 사회기술훈련, 환자교육, 가족교육, 집단치료, 예술치료, 작업치료와 같은 포괄적인 정신재활 치료를 약물치료와 병행할 경우 약물치료만 시행할 때에 비해 정신분열병 환자의 재발율, 입원횟수, 입원일수, 직접 치료경비 등에 어떤 효과가 있는 지를 알아보기 위함이다. 연구방법 : 1993년 9월부터 1995년 2월까지 양산 신경정신병원의 폐쇄병동에서 퇴원한 20∼35세 사이의 정신분열병 환자 173명을 대상으로 46명에게는 6개월동안 정신재활 치료를 시행하였고 127명에게는 통상적인 외래치료만 시행한 후 연구시작 시점을 포함하여 2년동안 양군에 속한 환자들을 대상으로 재발율, 입원횟수, 입원일수, 직접 치료경비 등을 1년 단위로 추적 조사하였으며, 연구시작 시점을 기준으로 전과 후의 매년 평균 입원횟수, 입원일수, 직접 치료경비도 서로 비교하였다. 결 과 : 정신재활 치료를 약물치료와 병행할 경우 약물치료만 시행할 때에 비해 재발율, 입원횟수, 입원일수, 직접 치료비용이 현저히 감소되었다. 그리고 정신재활 치료를 받은 군에서는 치료 전에 비해 치료 후에 재발율, 입원횟수, 입원일수, 직접 치료비용이 유의하게 감소하였지만 통상적인 외래치료만 받은 군에서는 치료 전과 후간에 유의한 변화를 보이지 않았다. 결 론 : 정신분열병 환자들에게 정신재활 치료를 약물치료와 병행할 경우 약물치료만 시행할 때에 비해 환자의 임상적 경과를 호전시킬 뿐 아니라 가족의 경제적 부담도 줄일 수 있다. Objective : We evaluated the clinical efficacy of a comprehensive psychiatric rehabilitation of schizophrenia, including family psychoeducation, patient education, social skills training, group psychotherapy, art therapy, and occupational therapy. Method : From September 1993 to February 1995, 173 chronic schizophrenics who met DSM-IV criteria and were discharged from a locked ward were assigned into the psychiatric rehabilitation service group(psychiatric rehabilitation group, n=46) or the customary out-patient service group(out-patient group, n=127) prospectively, but not randomly. Assignment was based on preferences of patients and their relatives, Each subject included in the psychiatric rehabilitation group received twice weekly patient education, social skills training, family psychoeducation, group psychotherapy, art therapy, occupational therapy and maintenance chemotherapy during a 6-month period. Those in the out-patient group received individual supportive psychotherapy and maintenance chemotherapy according to their clinical needs for 10-20 minutes once per week. After entry into the study, all subjects were assessed for the number of readmission, days of hospitalization, and the direct treatment costs through the first and second year of follow-ups. These outcome variables were also compared pre-and post-2 years at the time point of entry into the study. Aftercare chemotherapy on a weekly to monthly basis continued for the remainder of the two year follow-up period. Results : With regard to the mean number of hospital admissions per year, the mean days of hospitalization per year, and the direct treatment costs per year, the psychiatric rehabilitation group had significantly decreased all clinical outcomes 2 years after compared with before receiving psychiatric rehabilitation. But there were no significant differences in the all clinical outcomes between before and after study intake in the out-patient group. For the number of relapse regardless of drug compliance, 4 patients(9%) during first year and 14 patients(30%) during second year were relapsed in the 46 subjects of the psychiatric rehabilitation group. In contrast, 75 patients(59%) during first year and 90 patients (71%) during second year relapsed in the out-patient group. When considering the effect of drug noncompliance to relapse, 4(9%) and 14 patients(30%) were relapsed while on medication respectively during the first and second year in the 46 of the psychiatric rehabilitation group, vs. 27(34%) of 79 patients on medication during the first year and 31(46%) of 68 patients on medication during the second year were relapsed in the out-patient group. Conclusions : These results indicate that the comprehensive psychiatric rehabilitation can be useful therapeutic intervention both to improve the clinical outcomes of schizophrenic patients and to reduce the economical burden of their relatives.

Neurofibromatosis, first described by von Recklinghausen in 1882, is a dominantly inherited mesodermal and ectodermal dysplasia with a broad spectrum of clinical findings. Most clinicians know that von Recklinghausens neurofibromatosis denotes more than the dermatologic curiosity of cafe-au-lait spots. In this disease, neurofibroma can be found everywhere in the body, but gastrointestinal neurofibroma associated with von Recklinghausens disease is infrequently reported. Patients with this disease may experienee gastrointestinal hemorrhage, small bowel obstruction, malignant degeneration of neurofibromas. Recently, the authors experienced a case of simultaneously developed gastric neurofibroma and leiomyoma in a patient with von Recklinghausens disease and associated literatures were reviewed.

Purpose Thoracic empyema is defined as active suppuration within the pleural space and its treatment is controversial. Recently treatment of empyema is changing observation of empyema formation to early invasive treatment with the operation. This study compared the outcomes of early surgery and delayed surgery Method We retrospectively reviewed 40 patients who underwent surgery for complicated parapneumonic effusion from January of 2013 to May of 2020. The early group was defined as operation with empyema diagnosed within 1 week. Results Among 40 patients, 22 patients received early surgery, and 18 patients received delayed surgery. Stage III empyema was prevalent in the delayed group (27.3% vs 76.9%, p=0.004). Operative time was longer in the delayed group (87.5 vs 132.5 min, p=0.004). Intraoperative blood loss was more in the delayed group (200ml vs 750ml, p=0.009). The hospital stay was longer in the delayed group (18.5 days vs 30.0 days, p<0.001). The complication rate was not different between groups (31.8% vs 33.3%, p=0.919). The mortality rate was no significance between the two groups (4.5% vs 5.6%, p=0.884). Conclusion Delayed surgical treatment make operation difficult. Although inactive infected phase, early surgical treatment did not increase postoperative morbidity and mortality.

이 연구는 국내 프로배구 리그에 참가한 선수들의 경기력 수준을 알아보기 위한 규준을 제시하는 목적이 있다. 국내 프로배구 리그 경기 공식자료에 나타난 13개 요인을 활용하여 차이검증을 실시하고 동일집단군으로 형성하여 집단별 규준을 스테나인(Stanine) 방법으로 제시하였다. 또한, 상·하위 팀 선수들의 실제 기록을 규준에 적용해봄으로써 적합성을 검증하고 다음과 같은 결론을 얻었다. 국내 프로배구 리그에 참가한 선수들의 공식 기록을 수집하고 스테나인 방법을 적용시켜 포지션 별 규준을 분석한 결과 다음과 같은 결론을 얻었다. 첫째, 레프트와 라이트는 오픈·퀵오픈·시간차·후위·서브가 공통된 주요 요인이며, 센터는 속공과 블로킹, 리베로는 디그·범실·리시브, 세터는 세트가 주요인으로 나타났다. 둘째, 공격종합·오픈·퀵오픈·시간차·후위는 적용 포지션 별로 차이가 나타나지 않았기 때문에 통합하여 규준을 제시하였으며, 득점·블로킹·디그·범실·서브·리시브는 각각 나타난 동일 집단군으로 규준을 제시하였다. 또한, 속공과 세트는 특정 포지션만 적용하였다. 셋째, 제시된 규준점수에 적용하여 상·하위 팀 전체등급을 분석해본 결과 상위 팀은 3.77, 하위 팀은 4.92로 1.15의 등급 차이가 나타났다. 향후 이러한 방법을 적용하여 각 대회별 규준을 마련함으로써 참가 선수들의 수준을 파악하고 대회별 비교를 통한 연구가 가능하며, 대회 수준 및 특성에 맞는 등급제를 적용하는 것이 실제적인 선수 평가에 도움이 될 것이라 판단된다. This study aims to provide a record factor norm to measure performance of tennis players. The study, using 10 factors in the data from the Grand Slam in 2008 and 2009, performed one-way ANOVA, and provided the norm in Stanine method for each group. At the same time, the norm was applied to the 20 tennis players selected to verify robustness and the results are as follows. First, as for the differences in each match by the 10 record factors, differences were observed in 1st serve %, winning % on 1st serve, receiving points won, aces, double faults, unforced errors and winners. Second, no significant difference was observed in winning % on 2nd serve, break point conversions, net approaches from each match thus, a same norm grade to every match was applied, then the designed a norm by group for 1st serve %, winning % on 1st serve, receiving points won, aces, double faults, unforced errors, and winners. Third, the study rated each player`s record and analyzed average rate. The high rankers` average was about 2.30 to 4.20 while low rankers` average was 4.70 to 6.80. This study designed a norm in 9 scale with the data from the Grand Slam, however, it will be helpful to design practical norm for other matches with different level and different characteristics in measuring players` performance.

Background: Onychomycosis, especially toenail onychomycosis has become one of the common fungal infection and has historically been regarded as a cosmetic rather than medical problem by many patients, even by physicians. Recently, however, there are several reports that is a refractory disease which may cause a deleterious effect on patiets quality of life (QOL). Objective: The purpose of this study was to investigate the impact of toenail onychomycosis on QOL in Korea and to assess the chandes of QOL after treatment. Methods: Total 1004 patients with toenail onychomycosis which was confirmed by clinical findings and KOH preparation were were enrolled at 47 dermatologic centers in Korea, and interviewed with standardized QOL questionnaire before and after sytemic antifungal treatment. Responses to the questionnaire were scored by 5-point scale (1∼4) and averaged, and were analyzed for 5 dimensions of emotional impact, social impact, symptorn and functional impact, patients views concerning treatment, and relationship with doctor. Results: 1. Before and after treatment, the most serious impact was emotional dimension showing 1.90 and 1.30 in average score (AS), and social (AS: 1.14 and 0.83) and symptom and functional impact (AS: 1.05 and 0.92) was also affected. 2. In female rather than male, statistically more significant impact on patients QOL was observed in all dimensions. 3. After treatment, 3 of 5 dimensions were improved significantly - emotional dimension (AS : from 1.90 to 1.30), social dimension (AS: from 1.14 to 0.83), patients view concerning treatment (AS: from 1.34 to 1.02). 4. The drgree of patients satisfaction at the therapeutic effect was very high- 62.4% (immediately after treatment) and 65.8% (9 months affer initiation of treatment) of patients answered excellent or good. Conclusion: This study confirms that toenail onychomycosis has significant impact on the overall QOL of patients. Also the effect of antifungal therapy on patients QOL were watisfactory. Therefore, both doctor and patient should pay more attention to the treatment of onychomycosis. [Kor J Med Mycol 3(1): 115∼124]
