Self - Organizing 신경회로망을 이용한 영상 벡터 양자화
강혜숙(Hae-Sook Kang),전지애(Ji-ae Jun),차의영(Eui-Young Cha) 한국정보과학회 1992 한국정보과학회 학술발표논문집 Vol.19 No.2
벡터 정량화(Vector Quantization)를 이용한 화상 압축(image compression) 방법으로 LBG 알고리즘이 널리 알려져 있다. 그러나 이 알고리즘은 성능 면에서는 우수하나, 반복 알고리즘(iterative algorithm)이므로 코드북(codebook)의 생성에 많은 시간이 요구되어 실제의 화상 압축 기법으로는 적합하지 못하다. 그래서 최근에는 이러한 시간적 제약을 극복하기 위해 신경망(neural network)을 이용한 벡터 정량화 기법들이 나오고 있다. 이들 신경망은 경쟁 학습(competitive learning)을 하는 자기구성 신경망(self-organization neural network)의 형태로 스스로 입력 벡터들을 분류해서 빠른 시간에 코드북을 생성하는 장점을 갖는다. 그라나 성능 면에서 더 개선할 여지가 있다. 본 논문에서는 기존의 신경망이 가진 장점을 그대로 유지하면서, 보다 좋은 성능을 보이는 자기구성 신경회로망을 제안한다. 주어진 화상의 분포에 잘 적응하기 위해 초기 가중치를 임의로 설정하지 않고, 적용되는 입력 벡터들에 의존하여 유사성 판별에 의해 코드북의 크기를 정해가는 방식을 채택했다. 실험 결과 신경망을 이용한 이전의 방법들보다 성능이 개선되었음을 알 수 있다.

소아응급실을 내원한 환아 보호자의 미온수 마사지 경험실태
강혜숙 ( Hae Sook Kang ),윤오복 ( O Bok Yun ) 서울대학교 간호과학연구소 2010 간호학의 지평 Vol.7 No.1
Purpose: The purpose of this study was to investigate the guardian`s experience about tepid massage of children who visited Pediatric Emergency Room (PER). Methods: Data for this study was collected from August 1 to September 30, 2009 using questionnaires of 300 guardians who visited a PER. All data analyses were done using the SPSS 17.0 program and statistical data on frequency and percentage were obtained. x2 test was done as well. Results: The results of this study were as follows: 73.7% of the guardians were doing the tepid massage, and 40% of them were doing the tepid massage when guardians thought that their children had a fever. 8.6% of them were incorrectly doing the tepid massage on their children such as using ice or alcohol. 90.5% of the children`s condition changed when they had the tepid massage applied. Only 48% of the guardians got information about tepid massage, and 52.8% of the guardians got this information from the medical team. There were significant differences according to the education background about tepid massage (p<.001) and past hospital admissions history. There were differences according to whether their child had experience with febrile seizure(p=.085) and having more than one child at home (p=.085). Conclusion: This study revealed that the guardians were incorrectly doing the tepid massage on their children. The results of this study suggest that it is necessary to develop certain emergency nursing processes on accurate information and management strategies about tepid massage, and further studies on the effects of this kind education intervention are necessary.

Various chemical agents like surfactants or oxidants have been often used for the remediation of polluted railroad ballast gravels. In this study, novel physical remedaition method using alumina-type media for the treatment on a large-scale. A pilot-scale remediation system was prepared, and the treatment performance was tested under various conditions. It was observed that the treatment efficiency was better at high air pressure, more repetitive treatment, and more treatment time. However, the initial amount of gravels did not show significant effect on the performance because the initial amount (10 100 units) is within the range of the pilot-scale system. The economic aspect of this method will be analyzed to optimize the treatment condition of air pressure, number of repetitive treatment, treatment time, and amount of initial ballast.

Caffeine과 Amphetamine의 "흰쥐"동작에 미치는 영향
강혜숙,박영숙,변명현,전용선,주경빈 이화여자대학교 의과대학 1970 梨花醫學誌 Vol.- No.3
The present investigation was conducted to study on the behavioural effects of two central nervous system stimulants, caffeine and amphetamine. In grooming test, the behavioural changes in rats were markedly increased in small doses of caffeine(20mg/kg)and of amphetamine(1 mg/kg)as following order: head with the body, head with the forelimbs and body with the hindlimbs. The number of running was more increased by single doses of caffeine than of amphetamine but no significant differentiation were as seen as after single high does of caffeine(200 mg/kg)and of amphetamine(10 mg/kg). The number of rearing was not increased by single doses of both drugs. Repeated doses of caffeine(100 mg/kg)and amphetamine(5 mg/kg)did not induce any significant behavioural changes compaired with single small dose and single high dose.

Purpose: The purpose of this study was to describe the characteristics of children who visited the pediatric emergency department (PED) following an accident. Method: Data were obtained from the medical records of 4,010 children who visited the PED from January 1, 2004 through December 31, 2006. Data were analyzed using SPSS WIN 13.0 version. Results: The percentage of children who visited the PED for treatment following an accident was 14.9%. There were more boys (63.5%) than girls. The largest age group for children visiting the PED was preschool aged children. Slip downs were the most frequent accident (37.1%). The face was the most frequently injured area of the body (26.0%). Most (93.3%) of the children who visited the PED were classified as non-emergency, 6.5% as emergency and 0.2% as urgent. About 70.0% of children were examined and 50% of children were medicated. Fifty percent stayed in the PED department for less than 2 hours, and 88.0% of children were discharged to home. Nine percent were admitted, and 2.2% were transferred to other hospitals. Conclusion: The results of this study suggest the need for accident prevention education for parents, and the need to develop effective education for clinical nurses working in PED.
