1. Twenty-one cases of brain abscess treated at the Department of Neurosurgery, Seoul National University Hospital during the past 10 years from 1958 through 1967 were studied clinically. 2. Fifty-seven percents of the cases studied were under the age of 20. The ratio between male and female was 2:1. 3. The most important of the known sources of the infection was the infection of the middle ear which was responsible for 57% of total cases. Among others paranasal sinusitis, subacute bacterial endocarditis, cellulitis in face, osteomyelitis in skull, and head trauma were included. 4. Bacterial culture was performed in 12 cases. In 4 cases staphylococci were isolated; iri other 2, streptococci; and in still other 2, proteus. 5. Temporal abscess was found in 13 cases; cerebellar in 2, occipital, in. 2, parietal in 2, and frontal in 1 One case had temporal epidural abscess. 6. Headache was by far the most constant and common symptom and was found in 90%. Among .others fever, vomiting, L-A nausea were included. As sings 14 patients had stIffneek; 5, hemiparesis; 5, convul- sion; 4, hemiplegia and 2, homonymous helnianopsia. Papilledema was found in 9 cases. 7.

李東明 호남대학교 2001 호남대학교 학술논문집 Vol.22 No.1

The mistake of the method does not mean that the agent are confusing the object, but that the means and methods produce the unexpected results. This mistakes can be made within the same constitutional conditions and the different ones. The two theories - the existence of the intentional consummation despite the inconsistent results and the acceptance of the imaginary competition between the attempt of recognized facts and the mistakes of occurred facts are conflicting each other sharply. Therefore this study gathers the instances so far suggested centering on the mistakes of the methods, examines how the theory has been applied and how the precedents have treated the mistakes, and then puts forward the standards for the reasonable solution of the existence of the intentional consummation. The organization of this paper are as follow :. 1.Proposal of the problem 2.Case of the mistake 3.Existence of the intentional consummation 4.Conclusion

Purpose: The characteristics of hypoparathyroidism in patients with Hashimoto thyroiditis (HT) after total thyroidectomy are not well established. The aim of this study was to investigate the relationship between hypoparathyroidism and loss of parathyroid glands in patients with or without HT who underwent total thyroidectomy. Methods: Patients who underwent total thyroidectomy were divided into two groups; with HT (n=166) and without HT (n=526). Clinicopathologic characteristics were compared between the two groups. Results: The mean numbers of parathyroid glands in specimens were significantly smaller in the with HT group than in the without HT group (0.34±0.51 vs. 0.42±0.58, P=0.003). The rate of transient hypoparathyroidism was significantly higher in the with HT group than in the without HT group (51.8% vs. 34.6%, P=0.000). Serum total calcium levels in patients who experienced transient hypoparathyroidism did not differ significantly between groups (P=0.335). The incidence of transient hypoparathyroidism of patients who preserved all four parathyroid glands or sacrificed one parathyroid gland was higher in the with HT group than in the without HT group, although that of patients who sacrificed two or more parathyroid glands was similar between groups. The incidence of permanent hypoparathyroidism in the two groups did not differ (P=0.546). Conclusion: Patients with HT had a higher rate of transient hypoparathyroidism after total thyroidectomy, particularly patients who preserved all four or three parathyroid glands. It is likely that the blood supply to the parathyroid gland might be vulnerable in patients with HT. Therefore, even though all parathyroid glands were preserved, careful monitoring of hypoparathyroidism is necessary after total thyroidectomy in patients with HT.

Simple Bump-removal Scheme for the Position Signal of PM Motor Drives with Low-resolution Hall-effect Sensors

이동명 대한전기학회 2017 Journal of Electrical Engineering & Technology Vol.12 No.4

The vector control technique using low-resolution Hall-effect sensors has been widely used especially in consumer electronics. Due to electrical and/or mechanical unevenness related to binary-type Hall sensors, the calculated or estimated position information has discontinuities so called bumps, which causes the deterioration of vector control performance. In order to obtain a linearly changing position signal from low-precision Hall-effect sensors, this paper proposes a simple bumps in position signal removal algorithm that consists of a first-order observer with low-pass filtering scheme. The proposed algorithm has the feature of no needs for system parameters and additional estimation processes. The validity of the proposed method is verified through simulation and experimental results.

Analytic Model of Four-switch Inverter-fed Driving System for Wye or Delta-connected Motor with Current Ripple Reduction Scheme

이동명,김태형,허서원,정진우 대한전기학회 2016 Journal of Electrical Engineering & Technology Vol.11 No.1

This paper proposes an analytic model for four-switch inverter (FSI)-driven wye (Y) or delta (Δ)-connected motors with a current ripple reduction algorithm. FSIs employ four switches in controlling three-phase load instead of using six switches. They have split dc-link stage, and due to this inherent structure there exists the voltage difference between upper and lower capacitors, which results in distortion of the inverter output voltage. To study characteristics of FSIs, this paper presents an advanced simulation models of FSI-driven control system for 3-phase motor that can has a wire connection either Y or Δ. In addition, this paper introduces a current ripple reduction scheme that mitigates degradation of control performance due to the voltage difference between the dc-link capacitors. The validity of the proposed method and the analytic model is verified by simulations and experiments carried out with 1-HP induction machine with Y or Δ-connection

이동명,김창규,노병환,이승찬,강희동,Lee, Dong-Myung,Kim, Chang-Kyu,Rho, Byung-Hwan,Lee, Seung-Chan,Kang, Hee-Dong 대한방사선방어학회 2000 방사선방어학회지 Vol.25 No.4

1999년 7월부터 2000년 7월까지 대전지역에서 전알파/베타 대기부유진 연속모니터링 시스템과 기상측정 시스템을 이용하여 대기중 라돈자핵종 농도에 대한 시간별, 일별, 계절별 변동특성을 조사하였으며 동시에 기상인자가 미치는 영향을 고찰하였다. 그 결과 대기중 라돈자핵종의 일일평균 평형등가농도$(EEC_{Rn})$ 분포는 산술평균 $11.8{\pm}5.86Bqm^{-3}$ 과 기하평균 $10.3{\pm}4.57Bqm^{-3}$이었으며 일일 평균농도의 변동계수는 약 50%정도이었다. 매 30분마다 측정한 라돈자핵종의 평형등가농도는 최소 $0.80Bqm^{-3}$에서 최대 $43.3Bqm^{-3}$ 까지 하루 중 측정시간과 그때의 기상조건에 따라 변하였으나, 일일변동의 양상은 일출시점과 일몰시점에서 각각 최고농도와 최저농도를 반복하는 주기적인 양상을 보였다. 대전지역에서의 평형등가농도는 계절적으로 여름철이 낮고 늦가을이 높은 변동양상을 보여주었으나, 대기중 라돈자핵종 농도의 계절적 변동양상은 측정지역에 따라 달라질 수도 있을 것으로 예상된다. 대기중의 라돈자핵종 농도는 그 지역의 국지적 기상특성에 크게 좌우되었다. 특히 풍속이 $6msec^{-1}$ 이상이 되면 대기중의 라돈자핵종 농도는 $5Bqm^{-3}$이하로 급격히 떨어지는 반면에 대기중의 라돈자핵종 농도가 $30Bqm^{-3}$ 이상인 날은 풍속이 $1msec^{-1}$ 이하의 매우 고요한 날이었다. Continuous measurements of radon progeny concentrations in the open atmosphere and measurements of meteorological parameters were performed in Tajeon, using a continuous gross alpha/beta aerosol monitor and a weather measuring equipment between July 1999 and July 2000. These data were analyzed for half-hourly, daily, and seasonal variations. The distribution of daily averaged equilibrium equivalent radon concentration$(EEC_{Rn})$ had an arithmetic mean value of $11.3{\pm}5.86Bqm^{-3}$ with the coefficient of variation of about 50% and the geometric mean was $10.3Bqm^{-3}$. The $EEC_{Rn}$ varies between 0.83 and $43.3Bqm^{-3}$, depending on time of day and weather conditions. Half-hourly averaged data indicated a diurnal pattern with the outdoor $EEC_{Rn}$ reaching a maximum at sunrise and a minimum at sunset. The pattern of the seasonal variation of the $EEC_{Rn}$ in Taejon had a tendency of minimum concentration occurring in the summer(July) and maximum concentration occurring in the late autumn(November). But the seasonal variation of the $EEC_{Rn}$ is expect to vary greatly from place to place. The outdoor $EEC_{Rn}$ was highly dependent on the local climate features. Particularly the $EEC_{Rn}$an rapidly drops less than $5Bqm^{-3}$ in case of blowing heavily higher than wind speed of $6msec^{-1}$, reversely the days with more than $30Bqm^{-3}$ were at a calm weather condition with the wind speed of lower than $1msec^{-1}$.
