Monte Carlo Calculation of Thermal Neutron Flux Distribution for (n, v) Reaction in Calandria

김순영,김종경,김교윤,Kim, Soon-Young,Kim, Jong-Kyung,Kim, Kyo-Youn Korean Association for Radiation Protection 1994 방사선방어학회지 Vol.19 No.1

The MCNP 4.2 code was used to calculate the thermal neutron flux distributions for $(n,\;{\gamma})$reaction in mainshell, annular plate, and subshell of the calandria of a CANDU 6 plant during operation. The thermal neutron flux distributions in calandria mainshell, annular plate, and subshell were in the range of $10^{11}{\sim}10^{13}\;neutrons/cm^2-sec$ which is somewhat higher than the previous estimates calculated by DOT 4.2 code. As an application to shielding analysis, photon dose rates outside the side and bottom shields were calculated. The resulting dose rates at the reactor accessible areas were below design target, $6 {\mu}Sv/h$. The methodology used in this study to evaluate the thermal neutron flux distribution for $(n,\;{\gamma})reaction$ can be applied to radiation shielding analysis of CANDU 6 type plants. CANDU 6 중수형 원자로 운전중에 Calandria Shell내에서 발생하는 $(n,\;{\gamma})$ 반응유발 열중성자속분포와 CANDU 6 발전소의 측면 및 하단 차폐구조에서의 방사선 선량률을 계산하기 위하여 몬테칼로 방법을 이용한 MCNP 4.2 코드를 사용하였다. 계산결과, Mainshell, Annular Plate와 Subshell내 의 열중성자속분포는 $10^{11}{\sim}10^{13}\;neutrons/cm^2-sec$로 나타났고, 이는 DOT 4.2 코드의 계산결과와 비교해 볼 때 약간 큰 값들의 분포를 보여주고 있다. 이 계산결과의 응용으로서 작업자 접근가능지역 (Worker Accessible Areas)에서의 감마선량률을 계산해본 결과 설계목표치인 $6{\mu}Sv/h$보다 낮은 값을 주는 것으로 나타났다. $(n,\;{\gamma})$ 반응유발 열중성자속분포에 대한 MCNP 4.2 코드의 계산결과는 CANDU 6형 원자로의 방사선 차폐해석에 중요한 자료로 널리 이용될 수 있을 것이다.

무선통신채널에서 트렐리스 부호화한 16 QAM 신호전송을 위한 효율적인 페이딩 추정.보상방안

김순영,김정수,이광재,이문호 한국전자파학회 1999 한국전자파학회논문지 Vol.10 No.6

본 논푼에서는 주파수 선택적 레일리 페이딩 채널에서 16 QAM-TCM의 BER 성능을 개선하는 방법을 제시한다. 주파수 선택적 페이딩 환경에서는 ISI 등, 페이딩에 의한 성능열화가 극히 심하므로 이에 대한 보상 방안으로 가우시안 보상기법을 이용한 다중 파일롯 심별에 의한 보상 방법을 제안하였다. 또한 대역폭 확장 없이 우수한 부호화 이득을 얻을 수 있는 트렐리스 부호화 방법을 적용하였으며 연집 에러를 방지하고자 비트 리버설 블럭 인터리벙 기법을 개선하여 적용하였다. 컴퓨터 시율레이션 결과 주파수 선택적 레일리 페이 딩 환경에서 기존의 PSAM 방법을 적용한 것보다 우수한 성능 개선 효과를 확인 할 수 있었다 This paper presents the improvement of BER performance using fading compensation method for 16 QAM-TCM to reduce the effects of multi-path fading in mobile radio environments. We propose the multi-pilot symbol aided fading compensation technique using Gausian interpolation method for inter-symbol interference or fading distortion occured in frequency selective fading channel. The proposed system is combined coding and modulation scheme for improving the reliability of a digital transmission system without increasing the transmitted power or the required bandwidth. In the fading compensation, the pilot symbols from a known sequence is multiplexed into the data symbols at regular intervals to from a frames for transmission. And we use a modified bit reversal block interleaver to randomize burst errors. The results show that significant improvements in the bit-error rate performances can be achieved by the proposed techniques.

2,3,5-Triiodobenzoic Acid as an Inhibitor of Ethylene Forming Enzyme in Mung Bean Hypocotyls

김순영,강빈구,Kim, Soon-Young,Kang, Bin-G. Korean Society for Biochemistry and Molecular Biol 1987 한국생화학회지 Vol.20 No.2

오옥신 전달억제물질로 알려진 2,3,5-triiodobenzoic acid (TIBA)는 황화녹두 하배축 조직에서 오옥신유도 에틸렌 생성을 억제하였으며, 이러한 억제는 오옥신 전달억제와는 관련이 없다는 것을 알게되었다. 이 억제물질은 에틸렌 바로 전단계 중간대사물인 1-aminocyclopropane-1-carboxylic acid(ACC)에 의한 에틸렌 생성도 비슷한 양상으로 억제 시켰으며 또 조직에서 ACC의 축적을 증가시켰다. 이러한 사실은 TIBA가 ACC에서 에틸렌으로 전환되는 과정을 특정하게 억제한다는 것을 시사하고 있다. TIBA 가 free radical scavenger로서 작용할 가능성은 luminol chemiluminescene의 실험 결과 배제되었다. Mercaptoethanol을 이용한 실험결과는 TIBA가 ethylene forming enzyme에 sulfhydryl 억제제로 작용한다는 가능성을 뒷받침 하고있다. Auxin-induced ethylene production in hypocotyl segments of etiolated mung bean seedlings was severely inhibited by 2,3,5-triiodobenzoic acid (TIBA), a potent inhibitor of auxin transport. However. the inhibition of ethylene biosynthesis by the transport inhibitor was found to be unrelated to an obvious impairment of the auxin transport system. The inhibitor also suppressed ethylene production from segments fed with 1-aminocyclopropane-1-carboxylic acid (ACC). the immediate precursor of ethylene. TIBA treatment also led to a substantial accumulation of ACC in the tissue incubated with either auxin or ACC. These findings suggest that TIBA inhibits ethylene production by specifically blocking the conversion of ACC to ethylene. The possibility of TIBA acting as a free radical scavenger was ruled out by the lack of TIBA effect on chemiluminescence in a luminol-based system in vitro. Results obtained from experiments with mercaptoethanol suggest that TIBA may act as a sulfhydryl inhibitor on "ethylene forming enzyme (EFE)", the enzyme catalyzing the formation of ethylene from the penultimate precursor, ACC.

This study was performed to evaluate the effects of the combination of electroacupuncture (EA) and surgical decompression on paraplegia due to spinal compression in dogs. Ten clinically healthy dogs were assigned into two groups (group A and group B). The one is for the combination of EA and surgical decompression, and the other is for surgical decompression alone. After decompression, neurological function was evaluated daily with modified Tarlov grading system. SEPs were measured as objective evaluation of normal spinal cord function before spinal compression and after neurological recovery. The period of rehabilitation in group A was significantly shorter than that in groupB (p<0.05). Conduction velocity of SEPs showed a tendency to return to normal when the dogs got full recovery. According to these results, it was considered that the EA with surgical decompression was more effective than surgical decompression alone for paraplegia resulting from spinal cord injury in dog.

터보 부호에서 낮은 복잡도를 갖는 효율적인 반복부호 제어기법과 새로운 인터리버

김순영,장진수,성락주,이문호 한국통신학회 2000 韓國通信學會論文誌 Vol.25 No.8

In this paper, we propose a new turbo interleaver and an efficient iteration control method with low complexity for turbo decoding. Turbo codes has better performance as the number of iteration and the interleaver size increases. However, as the interleaver size is increased, it require much delay and computation for decoding. Thus we propose a new efficient turbo magic interleaver using the Magic square matrix. Simulation results show that the proposed interleaver realizes a good performance like GF, Mother interleaver proposed to IMT-2000. And as the decoding approaches the performance limit, any further iteration results in very little improvement. Therefore, we propose an efficient algorithm of decoding that can reduce the delay and computation. Just like the conventional stop criterion, it effectively stop the iteration process with very little performance degradation. 본 논문에서는 새로운 터보 인터리버와 복호와 과정에서 낮은 복잡도를 갖는효율적인 반복복호 제어기법을 제안한다 터보코드는 반복 복호수와 인터리버 크기가 증가할수록 성능이 향상된다는 것은 잘 알려진 사실이다 그러나 인터리버 크기가 증가하면 복호 과정에서 지연과 계산량이 증가하게 된다 따라서 새로운 효율적인 인터리버를 제안한다 제안 인터리버는 매직 매트릭스 특성을 이용함으로서 낮은 구현 복잡도를 가진면서 GF, Mother등 기존의 IMT-2000에 제안된 터보 인터리버와 비슷한 성능을 보인다 또한 터보 코드의 복호 과정에서 반복 복호수를 증가하면 성능이 향상되지만 어느정도의 반복 복호수 이상에서는 성능 향상이 거의 나타나지 않는 다 따라서 본 논문에서는 최대 반복 복호수를 수신 데이터를 이용 SNR(signal to noise ratio)을 추정하여 반복 복호수를 가변적으로 미리 설정(preset)함으로써 반복 복호수를 제어하는기법을 제안한다 제안구조는 터보 부호의 문제점 중 하나인 복호 계산량과 지연을 성능 저하 없이 효율적으로 감소시킬 수 있다

The purpose of this study was to determine the predictors of depression scores among newly diagnosed uterine cervix cancer patients before the hysterectomy or radiotherpy was done. A total of 55 patients from one university hospital in Kwang-ju city were interviewed from April 1996 to September 1996 with the aid of 6 structured instruments; Beck's Depression Inventory, Mishel's Uncertainty in Illness scale, Rosenberg's Self-esteem Scale, Tai's family support scale. Osgood's Sementic Differential scale, and records on demographic and medical factors. The data obtained were analyzed using percentage, t-test, AN OVA, Pearson correlation coeficients, and Stepwise Mutipie Regession. The results were summaized as follows: 1. The mean scores of psychosocial variables were as follows: uncertainty was 36.1, self-esteem was 35.5, body image was 39.9, familly support was 37.9. 2. The depression score was moderate degree in total subjects: the mean score of depression was 19.2 ± 9.5. 3. The depression score was not significantly different by the level of domographic and medical factors; age(p = .16), the education level(p = .25), the type of religion(p = .19), cancer staging(p = .36), and the presence or absence of ovary at operation(p = .62). 4. The higher the depression score they have, the lower they percived body image and self-esteem(r = -.477, p = .0002; r = -10, p = .002). But the scores between the depression and the uncertainty did not significantly correlate(r = .245, p = 0.072). 5. When self esteem was removed in the model because of multiple colliniarity, the stepwise procedure resulted in the body image, explaining 22.7%(β = -.856, p = .0005), of the variance in the depression scores. 6. When body image was removed in model because of multiple colliniarity, the stepwise procedure resulted in the self-esteem, explaining 16.8%(β = -.675, p = .0005), of the variance in the depression scores, cancer staging, explaining 8.9%(β = 3.363, p = .0155), respectively. The amount of the total variance was 25.7%. Based upon the above findings, it was concluded that the predictors of the score of depression was the body image, self esteem, and cancer staging.
