허혜경,박소미,김기연,김춘배,안정숙,송희영,김기경 韓國保健敎育.健康增進學會 2003 보건교육건강증진학회지 Vol.20 No.1

Purpose : The purpose of this study was to investigate the dietary habits of students in order to identify risk groups according to their Body Mass Index (BMI), and to compare the eating behavior of students in the normal range (19<I≤24) and those in risk groups (BMI≤19, 24<I≤27, BMI>). Method : 1176 elementary school students, 850 middle school students and 672 high school City, were the participants The instrument for this study was a structured questionnaire that included demographic data as well as dietary habits, and the eating behavior instrument developed by Stunkard &essick(1985) and revised by Kim &im (1997). Result : 1) As students moved up in grade level their dietary habits became more irregular and the degree that students chewed food was reduced 2) As students moved up in grade level, a greater number of the students did not eat breakfast. The reasons given were that there were not enough time before classes started(40.4%) and a lack of appetite in the morning(10.6%) in high school students. 3) As for supper, from 67.8 to 81.9% of subjects reported having regular supper. However the rest of the subjects did not eat supper because of anorexia and fear of weight gain. 4) The results identified risk groups according to their BMI showed that for elementary school students, 55.9% were in the low weight group, 5.5% in the overweight group, and 0.9% in the obese group. For middle and high school students, 40.6% and 35.5% respectively were in the low weight group, 7.4% and 6.3% in the overweight group, and 4.1% and 2.5% the obese group. 5) Comparisons of the eating behavior of students in the normal weight group with that of those in the three risk groups showed that there were significant differences in 'hunger' and 'cognitive restraint of eating' in elementary school students, and significant differences in 'cognitive restraint of eating' in middle and high school students. Conclusion : The results of this study show that management of diet in school health sholud be addressed from both the aspect of lack of nutrition and that of excess nutrition. In other words, good diet is as important for students in the low weight group as it is f3r those in the overweight and obese groups. The estatblishment of good dietary habits and eating behavior in students, by nurses and dieticians should be done by providing repeated diet education and involvement in diet counseling.

중성자와 우라늄의 핵반응에 의해 생성된 핵분열생성물의 물리적 특성을 이용하여 원자로 내의 핵연료 상태를 해석하는 모델을 개선하였다. 이 모델에서는 고체 핵연료 내에서 특정핵종의 핵분열 생성물의 생성과 이것이 원자로 냉각재까지 방출되는 과정을 계산하고 추적하며 방사능농도와 결합핵연료봉의 수를 관계짓는 방정식의 계수들을 결정한다. 핵분열생성물의 거동은 이탈(knock out)과 이동(migration) 두 부분으로 나누어 해석하였으며 트램프 우라늄의 영향을 분리할 수 있도록 하였다. 실측자료로는 가압 경수형 원자로인 고리 원자력발전소 1호기의 1차 냉각제를 분석해서 얻은 I-131과 I-133의 방사능 강도를 이용하였다. 이 실험자료와 위 방정식에서 구한 방사능 강도로부터 구한 결함 핵연료의 수는 제3주기에서 9.34±1.13개 제6주기에서 0.294±0.092개로 나타났다. An improved method of assessing fuel status by analysis of the fission product in the reactor coolant system is proposed. The release mechanism of specific fission products is established for determination of the coefficients in the equations which relate the radioactivities with the amount of defected fuel. Knock-out and migration models are employed in the formulation of the release mechanism. The influence of the tramp uranium is quantified. Sample calculations were made for KNU 1 reactor system using the I-131 and I-133 concentrations in the primary coolant. The estimated number of defected fuel pins in the third and sixth cycles appeared to be 9.34±1.13 and 0.294±0.092, respectively.

NACK 폭주 억제를 이용한 SRM 성능 개선

李演洙,金泰勳,朴惠蓮,李基鉉 明知大學校 産業技術硏究所 2003 産業技術硏究所論文集 Vol.22 No.-

In this paper, we deal with the Negative Acknowledgement(NACK)-Implosion problem that arises in the multicasting environment, and present a scheme to cope with this problem, the modified version of the Scalable Reliable Multicast(SRM) protocol, called SRM-K. This motivates this work in which the NACK message are generated depending on the congestion level inside the network. The occurrence of congestion is determined by estimating the round trip time (RTT) for each message. As an indication of the congestion level, we introduce a counter in each node, whose value K in dynamically adapted to the change of the network situation, namely increases when the congestion builds up and decreases otherwise. The proposed SRM-K scheme is evaluated by performing the simulation, showing that it outperforms the SRM, in particular, in the scenario when the network situation dynamically varies.

민해연,강연주,조경진,남영미 THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCINE 1995 Journal of biomedical laboratory sciences Vol.1 No.1

자동혈구계산기에서 산출되는 RDW나 MCV가 철결핍성빈혈의 구분진단에 어떠한 도움이 되는지를 보기 위하여 어는 대학병원의 최근 5년 동안의 의무기록과 건강진단결과를 이용하여 227명의 빈혈환자와 143명의 건강인을 선정하고 그들의 혈액검사 결과를 비교분석해 보았다. 분석결과 빈혈환자로서는 철결핍성빈혈과 재생불량성빈혈 환자가 많았으며, 그 외에 만성질환과 관련된 빈혈환자도 많은 것으로 나타났다. 정상인 들에 비하여 빈혈환자에서 RDW는 높게, 그리고 MCV는 낮게 나타났는데 특히 철겹핍성빈혈에서는 다른 빈혈에 비하여 19.3±4.8로 현저하게 높게 나타난 반면, MCV는 62.9±13.7fl로 현저하게 낮게 나타났으며, 그 빈혈의 정도에 따라 그 변화가 크게 나타났다. 빈혈관련수들을 이용하여 D.F.=0.26-0.012MCV-0.130MCH+0.073MCHC+0.052RDW+0.003PLT와 같은 판별함수가 도출되었고, 이를 토대로 철결핍성빈혈과 다른 빈혈을 구분하는데 있어서는 MCV, MCH, MCHC, RDW등이 판별력이 있다는 것을 확인 할수 있었다. RDW and MCV are thought to be the highly sensitive blood cell parameters in the differentiation of iron deficiency anemias. Through the medical records of 227 anemic patients and the physical checking results of 143 healthy persons in a General Hospital during the recent five years, the authors evaluated various blood cell parameters including RDW and MCV. Iron deficiency anemia, aplastic anemia and other anemias associated with chronic discase were shown as the three major causes of anemias in Korea. In the patients of iron deficiency anemia MCV was very low(62.9±13.7fL), while RDW was very high(19.3±4.8) showing much lower MCV and much higher RDW in severe IDA compared with in mild IDA. To differentiate iron deficiency anemias form other anemias, a discriminant function was developed from some blood cell parameters like MCV, MCH, MCHC, RDW and platelets(D.F.=0.26 -0.012MCV -0.130MCH+ 0.073MCHC +0.052RDW +0.003PLT).

압연 가공율이 Ag/Bi-2223 고온초전도 다심선재의 임계전류에 미치는 영향

오영우,이해연 경남대학교 신소재연구소 1999 論文集 Vol.11 No.-

Ag와 Bi 복합초전도 테이프 선재의 가공공정 중에 생성되는 산화물 초전도체와 피복재의 기계적 변형의 차이점을 분석하였다. 압연공정 동안 점차적으로 두께 감소율을 증가시킴으로써 최종 선재의 임계전류와 균일성을 향상시키고자 하엿으며, 이러한 공정을 통하여 피복재와 산화물 코어 사이의 종, 횡단 계면에 균일성을 향상시키고 소세지 현상을 감소시키는 균일한 응력이 선재내부에 적용되어졌다. 본 연구에서 적용된 압연공정으로 제조된 선재의 임계전류값이 기존의 압연방법으로 제조된 선재의 값보다 더 높고, 더 균일하게 나타났다. The difference in mechanical deformation of the cladding material and ceramic superconductor during cold working of Ag-sheathed Bi-based superconducting composite tapes has been analyzed. From this, an optimal rolling procedure has been developed in order to improve the uniformity and the critical current of the tapes by gradually increasing the reduction per pass during rolling. Using this technique, a uniform stress was achieved within the tapes which improved the interfacial homogeneity of the both transverse and longitudinal filaments and reduced the sausaging effect. An improved and more unifor-mity I_{c} was observed in tapes fabricated using this procedure than in those using a non-optimized route.

Purpose: This study was aimed to specify roles of nurses from the anesthesia and recovery room by analyzing nursing activities as well as anesthesia nursing during surgery. Method: The objects were 12 RNs working in the recovery room of a university hospital located in Incheon. Self-report was performed by measuring stop-watch for five days from May 17th to May 21st in 2004. Research method was designed to record the time and frequency of the nursing activity from anesthesia and recovery room based on nurses' statement and other references for five days. The data were analyzed with descriptive statistics, ANOVA, and t-test via SPSS Win 10.0 program. Result: Nursing activities in anesthesia recovery room were classified into two different characteristics such as direct and indirect nursing activity. The activities consisted of 11 direct nursing areas and 39 nursing activities in anesthesia preparation room. The indirect nursing was classified into 8 nursing areas and 32 nursing activities. The direct nursing was classified into 12 nursing areas and 55 nursing activity. Also, the indirect nursing was classified into 7 nursing areas and 21 nursing activities in recovery room. In terms of prevalence of nursing activities in the anesthesia preparation room, observation and cooperation of anesthesia was the most prevalent activity, drug and eqipment management the second prevalent, and drug administration the third. On the other hand, in the recovery room, the most prevalent activity was vital sign checking and observation, the second most prevalent activity informative activity, and the third body temperature control. Nursing activity time was recorded according to the nursing characteristics. In the anesthesia preparation room, the direct nursing spent for 8092.20 minutes was larger than the indirect nursing spent for 7198.50 minutes. Also, in the recovery room, the direct nursing spent for 2361.16 minutes was larger than the indirect nursing spent for 1134.13 minutes. 4. Nursing activity time was compared to duty shifts. In the anesthesia preparation room, the direct nursing was more prevalent on day shift and the indirect nursing was prevalent on evening shift. However, in the recovery room, both direct and indirect nursing activities were prevalent on day shift. Conclusion: The role of anesthesia and recovery room nurses was analysed according to the time, frequency, and its characteristics.
