BAM(Brewster Angle Microscope)으로 관측한 Langmuir막의 상전이에 따른 분자 배향에 관한 연구

조환제,강도원,박태곤 창원대학교 산업기술연구소 2001 産技硏論文集 Vol.15 No.-

In this study, we used Brewster-Angle Microscope(BAM) to study on the molecular orientation of monolayer on the water surface. The domains by behaviors of molecules on three different subphase have been observed. Reproducible π-A isotherm have been obtained only on information about phase transition by molecular area. BAM facilitates the observation of morphology by optical anisotropy and thickness in monolayer and multilayers as BAM is shown to be sensitive to anisotropy of film. Also, the coalescence of domains leads to large regions of uniform tilt-azimuthal direction. Every transition was found by BAM technique, either as a dramatic change in degree of contrast or as a sudden alteration of molecular action and π-A isotherm.

憲法上 地方自治團體의 計劃權限

Die ortliche selbstverwaltung hat einen grundlegenden wandel erfahren. Sie ist heute nicht als Grundrecht sondern als Prinzip der Staatsverfassung verstanden. Sie gehort einer Verwaltung. Also ist die Kommunale planungshoheit gegen Staat order uberortliche Kommune steht. Die ortliche Selbstverwaltung ist eine institutionelle Garantie, die eine objektive rechtsimstitutionsgarantie und eine subjektive Rechtsstellungsgrantie umfaβt. Sie raumt Kommune die Planungshoheit ein und ihr ein Eingriff von Staat und uberortliche Kommune absehrt. Hier spielen die Kernbereochsgarantie und das Ubermaβverbot wichtihge Rolle. Wegen des Gobot zur Rucksichtnahme soll Staat order uberorttliche Kommune die kommunale Planungshoheit achten. Fachplanungen oder uberortliche Reaumplace Konnen somit durch Bebaungsplane beschrankt werden. Und eine Kommune soll Bebaungsplane von anderen Kommune berucksichtigen. Es soll in Korea gelten.

인체의 골수는 간엽모세포를 함유하고 있으며 이들은 골수미세환경의 주된 세포들로 분화가 가능하여 조혈기능을 지지한다. 본 연구에서는 성별이 다른 동종조혈모세포이식 환경에서 조혈모세포의 완전 생착을 보이고, 이식 후 1년에서 8년이 지난 11예의 재생불량성 빈혈 및 백혈병 환자들을 대상으로 하여 골수에서 MSC를 분리하고 체외 확장을 통해 배양된 MSC에서 X 염색체 탐식자를 이용한 FISH 및 microsatellite polymorphism PCR 기법으로 그 기원을 확인하였다. 그 결과 조혈모세포는 완전히 공여자 기원으로 대치되었음에도 불구하고 MSC는 모두 수여자 기원임을 알 수 있어, 동종조혈모세포이식에서 미세환경의 구축은 수여자의 자가 생산에 의한 골수 간질세포에 의한 것으로 생각된다. Background: Human bone marrow (BM) contains mesenchymal stem cells (MSC) that can differentiate into various cells of mesenchymal origin. It remains a matter of controversy whether donor-derived stromal cells are capable of engraftment following hematopoietic stem cell transplantation (HSCT) or not. Methods: To determine if donor-derived stromal cells are transferred to the recipients of allogeneic HSCT, we investigated the characterization of MSC in 11 patients 1 to 8 years after sex mis-matched allogeneic HSCT in severe aplastic anemia and leukemia. Results: All patients had complete engraftment with donor- derived stem cells as shown by detection of donor type DNA in peripheral blood mononuclear cells. Following culture, MSC showed the expression of SH2 and SH4, but none of the hematopoietic markers of CD14, CD34, or CD45. MSC which can be differentiated to osteogenic lineage showed the genotype of recipient completely using FISH or PCR analysis. Conclusion: This study confirmed that MSC isolated from recipients of allogeneic HSCT in severe aplastic anemia and leukemia are not of donor genotype despite of full hematopoietic engraftment with donor type. Donor cells did not contribute to reconstitute the marrow microenvironment.

Teaching materials available for the effective performance of laboratory exp-erimental work in middle school were developed: Physics part ; A measuring apparatus of uniformly accelerated motion and normal force of inclined plane was developed. Chemistry part ; An imploved Eudiometer applicable in measuring reaction mole ratio and usful for a gas generating apparatus was developed. Biology part ; convenient teaching materials observing law of dominance, law of segregation, law of independence, incomplete dominance and dihybrid cross were developed. Earth science part ; A laboratory teaching materials observing formation of wave, current and graded bedding, and identification of sedimentary rocks were developed. Putting the above results of study together, the integrated suggestions were made to the effective development of science education in middle school : 1. The contents of science textbook should be simplified to the direction of the understanding of essential principles and concept. 2. The development and dirtrihbution of various supplementary teaching materials (film, T.P., cassettes film, supplementary textbook, program teaching materials individual learning materials) are required. 3. The experimental laboratory should be equipped with common instruments and equipements. 4. Efforts and time are needed to science teachers, and so remission of sundry duties and arrangement of assistant are hopefully considered. 5. Teacher's research activities should be encouraged by administrative route or relevant institute.

Convenience is key benefits in today's market place. Fresh Convenience Foods enable the consumer to save time and effort in food activities, related to shopping, meal preparation and cooking, consumption and postmeal activities. The objective of this study is to analyze the labeling system associated with Fresh Convenience Foods in Korea. Since there is some inconsistency on regulations in the Acts, this study recommends that Acts needs to be merged into the integrated act to keep consistencies. Also, the related Acts should be clearly identified through harmonization of Fresh Convenience Food classification criteria and the labeling system in food items should be expanded at products based to increase the relevancy between raw products and processed foods.

School lunch program provides both health and education service. School lunch program targets on properly educating students which requires both safety and sanitation, and regulations and methods should be ready in order to prevent foodborne disease. But there are many weak points which current School Lunch Act can be used as a mean to prevent many sanitary problems. In order to settle school lunch program safely, programs must alleviate direct management in law and reduce responsibility of parents’ of the cost. In other side, preventing re-occurrence of similar foodborne disease is needed by detecting and improving all problems every step after the accident take place.

화상 환자에서 발생한 외과적 중재술을 요하는 감염성 심내막염 2예

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.
