Background: There have been many efforts to augment blood flow during cardiopulmonary resuscitation. These efforts have focused on maximizing the effect of cardiac pump or thoracic pump alone. However, considering that the heart is the biggest blood reservoir and increase of intrathoracic pressure can generate blood flow, simultaneous exploitation of both mechanisms may have synergistic effect. We hypothesized that simultaneous chest constriction in addition to sternal compression by standard CPR may have additive hemodynamic effects by preventing deformation of the chest and increase of intrathoracic pressure. Methods and results: we built a new mechanical device to perform compression and thoracic constriction simultaneously. The device consists of two main elements. Piston in the center is to depress the sternum. Strap is to constrict the thorax circumferentially. Strap is attached to both sides of the piston. When the piston is pushed down, it depresses the sternum and pulls on the thoracic strap. To determine strap width to produce optimal hemodynamic effect, we measured hemodynamic parameters with variable widths of strap in two dogs after induction of ventricular fibrillation. Result of the experiment showed that 10cm wide strap was determined to be most effective. We also determined optimal depth of compression to produce maximal hemodynamic effect with animal experiments using two dogs. Animal experiments showed that the highest aortic pressure could be generated when the stemum was depressed to 5 cm. Cardiopulmonary resusciation using a new device could generate higher systolic aortic pressure, coronary perfusion pressure and end-tidal carbon dioxide tension in comparison with standard cardiopulmonary resuscitation in a pilot animal study using two dogs. Conclusion: New cardiopulmonary resuscitation method using a mechanical device designed by us could perform sternal compression and simultaneous thoracic constriction, and generate better hemodynamic effects than standard cardiopulmonary resuscitation in pilot animal experiments.

Nowadays, remodeling has been encouraged as an alternative since reconstruction has caused a lot of problems. The best way to activate the remodeling may be the financial value improvement through it. Thus, this research aims to analyze the priority of various remodeling programs in view of financial value improvement. To attain a goal of research, hierarchical structure of remodeling programs is organized and questions to various experts are posed. Question results are analyzed by way of AHP(Analytic Hierarchy Process) method. As results, in both case 1 and 4, the priority of high elements is decided in order of: increase of effective area, improvement of convenience and internal·external appearance, application of environment-friendly;health systems, application of energy conservation systems, application of intelligent communication systems. In the priority low elements, overall tendencies are just alike even if there are some differences in priority of each item between case 1 and 4.

RBL-2H3 세포에서 IgE-dependent Histamine-releasing Factor의 탈인산화 효소에 관한 연구

황선옥,이경림 이화여자대학교 약학연구소 2005 藥學硏究論文集 Vol.- No.15

IgE-dependent histamine0releasing factor(HRF) was initially described as a secretagogue for secretion of histamine from IgE+basophils from a subset of allergic donors. Previously, we identified that S98 residue of HRF was phosphorylated using anti-HRFpS98 antibody which specifically recognizes the phosphorylated serine residue of HRF and HRFS98A mutant construct. In vitro kinase assay, only wild type HRF was phosphorylated by PKC, and S98A HRF was not affected by PKC. in this study, we attempted to characterize the phosphatase which specifically dephosphorylates HRF by immunoprecipitation and pull-down assay. In RBL-2H3 cells, HRF interacted only with calcineurin (also called as PP2B, calcium/calmodulin-dependent phosphatase ) but not with PP1 or PP2A. The results suggest that HRF is most likely dephosphory lated by calcineurin.

We describe the distance learning at campus network. Many schools are now focusing on producing effective local network. Distance learning are using the PC, workstation, multimedia devices and be linked together. Distance learning has many distinguish characteristics: ① digital libraries. ② registration systems. ③ interation with legacy systems. And multimedia is material presented in a combination of text,graphics, video, animation and sound. A tool that gives the information product designer the freedom to link various kinds and pieces od data in a variety of ways so that students can moves through it campus network. A system capable of presenting multimedia material in its entirety.

The purpose of this study was to investigate the effects of a saleswoman s clothing and store type on elderly female consumers likability to a saleswoman. Also it was to study the effects of the factors consisting likability to a saleswoman on intent to purchase among eldery female consumers. 3(clothing formality: low, medium, and high)×2(clothing style: clothing looking old vs. young)×2(store type: high priced specialty store vs. low priced open market) complete randomized between subjects design using field experiments were conducted. Subjects were 240 elderly females aged 54-69. The results showed that likability to a saleswoman consisted of impression factor, service ability factor and caring factor. There was the significant three way interaction among three independent variables in the service ability factor (F_2.228=15.62, P<.001). Regression Analysis showed that the impression factor(R^2=0.29, F<.001) and the service ability factor(R^2=0.06, F<.001) influenced the elderly consumers intention to purchase significantly. In conclusion, favorable appearances of a saleswoman is considered a crucial service quality influencing potential elderly consumers to purchase.

방사성폐기물 처리, 처분의 안정성 평가를 위하여 방사성 고화체에서 용출되는 137Cs과 90Sr의 방사능 용출율과 누적용출분율을 계측·분석하여 시멘트를 사용한 방사성 고화체에서 Cs+과 Sr++의 용출특성을 조사하였다. 모의방사성 폐액의 몰농도, 시멘트의 종류, 첨가물질 및 붕산농도 등을 변화시키면서 sodium silicate법과 중화법으로 원주형 시멘트 고화제를 제작하였다. 여기에서 가압경수로형 원자력 발전소의 모의 농축폐액의 시멘트 고화체로부터 용출연구는 IAEA의 추천방법에 따라서 수행되었다. 실험결과는 대부분 이미 보고된 연구자료들과 잘 일치하고 있으나 수밀성 시멘트 고화체에서는 상당히 높은 방사능 용출율을 보여주고 있음으로써 방사성 폐기를 고화체에 그 사용이 적합하지 않음을 알게 된다. For the safety assessment of radwaste treatment and disposal, the leaching characteristics of Cs++ and Sr++ from the cement-solidified radwastes was investigated by means of the survey and analysis of the activity leach rate and cumulative leach fraction of 137Cs and 90Sr leaching from solidified radwastes. The cylindrical cement-solidified samples were made by the sodium silicate method and neutralization method changing the mole density of simulated liquid radwaste, type of cement, adding material and concentration of boric acid. The leaching study was carried out by the method using simulated PWR concentrated liquid radwaste solidified in cement that had been processed following the recommendations of IAEA. All the experimental results are in well accordance with the research data reported previously, but the watertight cement-solidified radwastes show rather high leach rate of radioactivity. It is learned, therefore, that the watertight cement is not adequate as the material for the solidified radwastes.
