陸鍾澈,李鍾一,河正雨 대한방사선 방어학회 1988 방사선방어학회지 Vol.13 No.1

영광 원자력 발전소 영광 1, 2호기로부터 대기방출되는 I-131에 의한 주민피폭선량을 ICRP 29에서 제안한 계통해석법(system analysis method)으로 계산하였고, I-131의 연간 섭취에 의한 갑상선의 실효 예탁선량당량을 ICRP 29와 ICRP 30의 개념을 결합하여 계산하였다. 그리고, 계산에 사용한 모델의 감도(sensitivity)와 견고도(robustness)도 아울러 분석 평가하였다. 단기방출에 따른 최대 연간 개인피폭선량 계산결과는 정상가동에 따른 연속방출가정에 의한 계산결과보다 1.4내지 1.7배나 높았고, 연간 핵연료 손상율이 0.12%인 경우, 갑상선에 대한 집단피폭선량은 3.05×10 -3 man-thyroid-Sv으로서 GASPAR 전산코드에 의한 값 2.3×10 -3 man-thyroid-Sv보다 높았다. 사용한 모델의 평균 견고도 지수는 0.5이하로 변수값에 많은 영향을 받는 것으로 나타났으며, 경구섭취를 통한 각 피폭경로의 감도 게산결과 유아의 경우는 우유를 통하여, 그리고, 소아, 십대 및 성인의 경우는 농작물을 통한 피폭이 가장 민감한 것으로 나타났다. The annual individual and collective doses to the thyroids of four age-dependent groups due to the intake of 1-131 released from the Younggwang nuclear power plant NU-1 & 2, Korea, are estimated using the model presented in ICRP 29. Sensitivity and robustness of the model are analyzed. In case of 0.12 % fuel defect during normal operation, the collective dose is founded to be 3.05×10 -3 man-thyroid-Sv, which is higher than the value calculated by the GASPAR code, 2.3×10 -3 man-thyroid-Sv. The maximal individual annual doses resulting from an acute release are higher than those calcualted under the assumption of continuous release by 1.4~1.7 times. The most important pathway to the infant is milk and, in contrast, that to child, teen and adult is ingestion of crops. The model used is the calculation appears to be influenced by the variables such as roubstness-index. The weighted committed dose equivalent obtained by the ICRP 29 model is slightly higher than that calculated by the three-compartment model.

We compared the gene expressions in primary and metastic tumor cells derived from two oral squamous cell carcinoma patients. cDNA was synthesized from RNA of primary and metastic tumor cells and amplified with arbitrary primers by polymerase chain reaction. cDNA of increased and decreased gene expression on 6% denaturing polycrylamide gel eletrophoresis was confirmed by dot blot hybridization. We identified 9 cDNAs of increased gene expression and 3 cDNAs of decreased in both merastatic tumor cells. But the gene expression of others was increased or decreased in one of two metastatic tumor cells .These result imply that the pattern of changes of gene expression in metastasis was different in different patients.

코쉬섬 1차 반복 형태의 마이크로스트립 패치 안테나에 관한 연구

In this paper, the microstrip patch antenna applying the koch island fractal geometry is introduced in order to reduce the antenna patch size. By space-filling property of fractal geometry, the microstrip patch applying koch island has low frequency compared with square patch antenna. In the case of 1st order iteration patchs are investigated by simulator and experiment. Through this, it is found that as the fractal iteration factor increase, the resonant frequency of koch island patch is lower. therefore koch island patch antenna can reduce patch size compared with square patch antenna. and The fabricated patch antenna is matched by using quarter wave length impedance transformer and return loss and radiation patterns are measured. The measurement result shows that the copolarization pattern of koch patch is similar to that of square patch. The cross polarization power level is -15∼-20dB.

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.

X-선 발생장치 시설의 방사선 차폐 해석

문석형,최호신,권석근,육종철 대한방사선 방어학회 1987 방사선방어학회지 Vol.12 No.1

X-선 발생장치 시설에 대한 방사선 차폐해석은 두가지 측면에서 고려된다. 먼저 1차 방사선과 누설방사선에 의한 영향을 고려하여야 하며 본 연구에서는 NCRP-49 및 51에 제시된 방법을 사용하였다. 둘째, 시설의 미로 출입구에서는 산란방사선에 의한 영향이 보다 중요한데, 본연구에서는 이 영향을 평가하기 위하여 Albedo개념을 근거로 한 단순한 방법이 제시되었고, 이를 토대로 계산된 결과를 컴퓨터 코-드(MORSE-CG)의 계산치 및 실측된 결과와 비교하였다. 본 연구에서 제시된 방법에 의한 결과는 미로출입구 안쪽의 경우에 대한 해석에서는 약간의 오차를 보이고 있으나 미로출입구 문바깥에서는 비교적 잘 일치한다. 여기서 출입문바깥의 경우에 대한 해석이 방사선방어 측면에서 보다 중요하다는 관점에서 볼 때 이 방법은 의료용 또는 산업용의 X-선 및 감마선시설의 차폐설계 및 해석이 응용될 수 있을 것이라고 판단된다. Radiation shielding analysis for a 6MeV X-ray facility was carried out. The primary and leakage radiation for the facility can be evaluated based on the methodology in NCRP No. 49 and 51. The present study deals with radiation scattering analysis for the outside and inside door of the facility based on the albedo concept. The calculated dose rates were compared with the results of MORSE-CG code calculation and the measured data, resulting in a good agreement, even though there existed some deviation for the inside door. These results can be utilized to the radiation shielding design of the medical and industrial X and gamma ray facilities, and to the safety evaluation of these facilities.

Time Frequency Domain Reflectometry 기법을 이용한 Coaxial Cable에서의 결함 감지 및 추정

본 논문에서는 도선사에서 발생하는 결함 위치와 이상 유무를 감지하는 새로운 고분해능 반사측정법인 시간-주파수 영역반사측정법 (TFDR, Time-Frequency Domain Reflectometry)을 제안하였다. 고전적인 반사측정법들은 단지 시간 또는 주파수의 한 영역에서 분석되어져 왔으나, 본 논문에서 제시한 TFDR은 도선의 결함 위치와 이상 유무를 발견하기 위해 과도신호의 시간과 주파수 영역의 정보를 동시에 이용할 수 있는 시간-주파수 분석기법으로 특성화하였다. TFDR의 기준신호 설계는 측정 케이블의 물리적 성질들을 고려하여 주파수 밴드를 결정하며, 도선의 결함감지와 추정은 시간-주파수 상호상관관계 함수에 의해 이루어진다. TFDR 시스템을 이용하여 여러 결함 상태를 가진 실제 coaxial cable (RG-142, RG-400)에 대해 실험하였고 정확성을 입증하기 위해 TDR (Time Domain Reflectometry) 장비와 성능은 비교하였다. 본 논문에서는 TFDR이 TDR보다 작은 오차로 결함을 찾아냄을 나타내고 있으며, 측정된 정확도는 TFDR의 오차율이 0.5%이하로 TDR (54750A/54754A) 장비보다 성능이 월등히 우수하다는 것을 알 수 있다. In this paper, a new high resolution reflectometry scheme, time-frequency domain reflectometry (TFDR), is proposed to detect and locate fault in wiring. Traditional reflectometry methods have been achieved in either the time domain or frequency domain only. However, time-frequency domain reflectometry utilizes time and frequency information of a transient signal to detect and locate the fault. The time-frequency domain reflectometry approach described in this paper is characterized by time-frequency reference signal design and post-processing of the reference and reflected signals to detect and locate the fault. Design of the reference signal in time-frequency domain reflectometry is based on the determination of the frequency bandwidth of the physical properties of cable under test. The detection and estimation of the fault on the time-frequency domain reflectometry relies on the time-frequency domain reflectometry is compared with commercial time domain reflectometry (TDR) instrument. In these experiments provided in this paper, TFDR locates the fault with smaller error than TDR. Knowledge of time and frequency localized information for the reference and reflected signal gained via time-frequency analysis, allows one to detect the fault and estimate the location accurately.
