This study was undertaken to improve the perceived value of halophytes and contribute to the activity of the local economy by analyzing the antioxidant activity and mineral content of Suaeda japonica, Tetragonia tetragonoides, and Spergularia marina that grow wild on the mud flats and coastal areas. The total phenolic compound content found in each order is as follows: Suaeda japonica (3.674∼5.989 mg TAE/g dry wt.), Tetragonia tetragonoides (2.515∼4.471 mg TAE/g dry wt.), and Spergularia marina (2.450∼4.067 mg TAE/g dry wt.); DPPH radical scavenging and ABTS cation radical scavenging activities were also recorded in the same order. In the case of minerals, Iron(Fe) was relatively high in Suaeda japonica (960.1∼1,346.7 mg/kg), Manganese(Mn) in Tetragonia tetragonoides (197.1∼574.8 mg/kg), and Zinc(Zn) was relatively high in Spergularia marina (63.19∼216.56 mg/kg). It was confirmed that the mineral content of Suaeda japonica, Tetragonia tetragonoides, and Spergularia marina was significantly higher than that of Chinese cabbage, lettuce, leek, and spinach.

It is very important for the learners to develop their ability to judge, select subjectively and learn information and knowledge necessary for themselves in the current open society towards learning. In this respect, for the development of this ability, school education must put a stress upon the premises that learners can prepare for the basis of learning for continuing education in the course of life and that they can develop the self-directed learning ability in order to think themselves and to search for a truth. Therefore, this study aims to develop instructional model so that the learners can improve a self-directed learning ability through school education. The questions for research are raised for a successful investigation as follows: First, what characteristics do the constituent factors of children have in their self-directed learning ability? Second, what is the concrete plan for the improvement of constituent factors in their selfdirected learning ability? Third, what is the integrated intructional model for the improvement of self-directed learning ability in children? The conclusions can be obtained in this study as follows: First, it can be proved that children have an ability in all the constituent factors of self-directed learning ability such as openness, self-concept, intrinsic motivation, autonomy, creativity, ability to problem-solving, self-evaluation and so on, but that their ability in specific constituent factors show lower than adults. Second, the individual teaching plans for the improvement of self-directed learning ability can include the establishment of purpose, preparation of conditions for learning, forning human relationship, supporting learning, the organization of learning group, proper homework, learning contract, the chances of the various experience and practice, self-evaluation, the role of teachers and so on. Third, the plans for the improvement of self-directed learning ability through analysis of study and instructional model which the improvement of children’s self-directed learning ability are meaningful learning matters, teacher’s activities, learning context, environment of learners, meaning creation of learners, learning contract. Fourth, the integrated instructional model for the improvement of self-directed learning ability consists of learners’ activities, and teachers’ activities are suggested in order to guide, promote and instruct learners’ activities. This is to put an emphasis upon the mutual cooperation between children and their teachers after due consideration into characteristic of children’s development during instruction. The activities of learners include the choice of subject for learning, meaning creation of learners, the establishment of concreate learning target self-evaluation, evaluation of comrade and self-reinforcement. The activities of teachers include preparation of conditions for learning based upon the various conditions of information, the choice of subject for learning and its suggestion, offering motive for learning creation, controlling members of group, evaluation of performance, and teachers’ reinforcement. Teaching by this integrated instructional model will enable children to develop their own ability of the specific constituent factors wanting, and this will promote elementary school children’s self-directed learning ability.

박정숙,이영호,최안홍,노신애,김태겸,한진영 대한조혈모세포이식학회 1998 대한조혈모세포이식학회지 Vol.3 No.1

연구배경 : 최근에 보고된 변형적 Ficoll-Hypaque 방법을 이용한 제대혈 분리방법이 지금까지의 고식적 Ficoll-Hypaque 분리방법에 비하여 조혈모세포의 수득효과면에서 얼마나 차이가 있는지 또한 비교적 수득효과가 크다고 알려져 있는 3% gelatin을 이용한 분리방법에 비하여 얼마나 효과적인지를 알아보고, 제대혈 분리방법의 차이에 따라 단핵구와 조혈모세포 사이에 어떤 상관관계가 있는지 알아보기 위하여 본 연구를 시행하였다. 방법: 21명의 건강한 산모로부터 정상 질식 및 제왕절개 분만 후 제대정맥에서 해파린 처리한 주사기를 사용하여 제대혈을 채취하였다 채취한 제대혈은 동일하게 3개월 시험관에 나누어 실온에서 24시간 이내에 고식적 Ficoll-Hypaque분리법, modified Ficoll-Hypaque 분리법, 3% gelatin 분리법을 이용하여 각각 단핵구 분리를 시도하였으며 이들의 단핵구수 및 생존률, CD34 양성세포수, 집락수를 측정 비교 하였다. 또 상관분석을 이용하여 단핵구수, CD34양성세포수와 CFU-GM집락수 사이의 상관관계를 알아보았다. 결과: 1) 세포 생존률은 고식적 Ficoll-Hypaque 분리법, 변형적 Ficoll-Hypaque 분리법, 3% gelatin 분리법 사이레 통계적 차이가 없었다. 2) 단핵구수는 3% gelatin으로 분리했을 때가 4.56±1.86 (×10^(6)/mL)로 수득효과가 가장 높았으며 (P=0.0001), Ficoll-Hypaque으로 분리했을때는 각각 1.54±0.06(×10^(6)/mL), 1.36±0.67(×10^(6)/mL)로서 고식적 방법과 변형적 방법 차이에 통계적 차이가 없었다. 3) CD34 양성세포수는 3%gelatin으로 분리했을 때가 6.08±3.99(×10⁴/mL)로 수득효과가 가장 높았으며 (P=0.0001), Ficoll-Hypaque으로 분리했을 때는 각각 2.18±2.17(×10⁴/mL), 2.24±1.63(×10⁴mL)로서 고식적 방법과 변형적 방법사이에 통계적 차이가 없었다. 4) CFU-GM 집락수는 3% gelatin으로 분리했을 때가 15.72±8.93(×10³/mL)로 수득효과가 가장 높았으며 (P=0.0002), Ficoll-Hypaque으로 분리했을 때는 각각 3.12±1.45(×10³mL), 2.35±0.82(×10³/mL)로서 고식적 방법과 변형적 방법 사이에 통계적 차이가 없었다, 5) 제대혈 고식적 Ficoll-Hypaque 방법으로 분리하였던 경우는 단핵구수와 CFU-GM집락수 사이에 상관관계가 없었으며CD34 양성세포수만 CFU-GM집락수와 상관관계가 있었다. (r=0.57). 또 변형적 Ficoll-Hypaque 방법에 의하여 분리하였던 경우는 단핵구수나 CD34 양성세포수 모두가 CFU-GM 집락수와 상관관계가 없었다. 그러나 제대혈을 3% gelatin법으로 분리하였던 경우는 CFU-GM집락수 가 단핵구수 (r=0.88) 및 CD34양성세포수(r=0.86)양자 모두와 상관관계가 있었다. 결론 : 3%gelatin을 이용하여 제대혈을 분리하는 것이 단핵구 및 조세모세포의 수득효과면에서 가장 효과적이었다. 한편 변형적 Ficoll-Hypaque 분리법이 고식적 Ficoll-Hypaque 분리법보다 시간과 경비면에서 비효율적이면서 수득효과도 높지 못하였다. 또 제대혈 분리법의 차이에 따라 단핵구나 CD34 양성세포와 VFU-GM사이에 상관관계에 차이가 있었으며, 실제로 제대혈이식 후에 생착 여부를 예측할 수 있는 인자가 제대혈 분리법의 차이에 따라 달라지는지에 관해서 보다 많은 임상적 연구가 필요할 것으로 사료된다. Background : Cord blood banking for stem cell transplantation requires volume reduction and red cell depletion for cost effective storage. To determine which technique could minimize the loss of progenitor cells during cord blood processing, we compared the efficacy of cord blood separating methods which were conventional Ficoll-Hypaque method, modified Ficoll-Hypaque method, and 3% gelatin method. Methods : Twenty-one cord blood samples were obtained with heparinized syringes from the umbilical vein following delivery. Three aliquots of each 20mL cord blood were stored at room temperature and processed by 3 different techniques within 24 hours after collection. We compared mononuclear cells(MNCs) counts and their viability, CD34+ cells counts, and CFU-GMs counts and also observed their correlations among three techniques. Results : 1) The yield of MNCs or CD34+ cells was highest in the cord blood processed with 3% gelatin method than conventional or modified Ficoll-Hypaque method(P=0.0001). 2) There were no significant difference in the yield of MNCs and CD34+ cells between conventional and modified Ficoll-Hypaque method. 3) Both MNCs counts (r=0.800) and CD34+ cells counts (r=0.86) were significantly correlated with CFU-GM counts in the cord blood processed with 3% gelatin method. 4) CD34+ cells counts were significantly correlated with CFU-GM counts in the cord blood processed with conventional Ficoll-Hypaque method (r=0.57), but MNC counts were not. 5) Both MNC counts and CD34+ cell counts were not correlated with CFU-GM counts in the cord blood processed with modified Ficoll-Hypaque method. Conclusion : Cord blood separation with 3% gelatin method could provide better yield of progenitor cells than with FICOLL_Hypaque methods. And between two Ficoll-Hypaque methods, modified method is more laborsome but not better in terms of clonogenic potential than conventional method.

감염성 심내막염은 화상 후에 발생할 수 있는 치명적인 합병증이다. 임상 증상은 일반적으로 없는 경우가 대부분이고 지속되는 발열과 양성 혈액 배양 검사가 유일하다. 감염의 다른 확실한 원인 없이 발열과 양성 혈액 배양 검사가 있을 때는 감염성 심내막염을 강력하게 의심해야 하며 심장 초음파로 진단 가능하다. 감염성 심내막염은 사망률은 높지만 초기에 진단하면 항생제 정주를 지속하는 것으로 치료할 수 있다. 저자들은 화상환자에서 발생한 수술적 처치를 필요로 하는 감염성 심내막염 2예를 경험하였기에 보고하는 바이다. Infective endocarditis is a rare but fatal complication following burn injury. The clinical presentation is silent, but with persistent fever and positive blood culture. The manipulation of clinical care as well as the burn wound itself and immunosuppression caused by extensive bums puts the burn patients at risk of bacteremia. Staphylococcus aureus and Gram-negative bacilli are most common pathogens of infective endocarditis following burns. We report herein two cases of infective endocarditis in the burn patients who requires surgical intervention. The first case was caused by Pseudomonas aeruginosa with complication of multifocal pneumonia, and the second case by coagulase-negative stapylococcus with cerebral hemorrhage.
