Purpose Recently, there has been increasing demands for clinical departments at Asan Medical center in Seoul. They want to see the results of lab tests about blood samples as soon as possible and to be reported to them on the day. As the main contents of the survey, we explained the goodness of Asan medical center's in vitro and the points to be improved. Based on this, it became an opportunity to create a positive image of In vitro laboratory. In addition, we could identify their specific requirements through the surveys. Materials and Methods In September 2016, a total of 14 questionnaire surveys were conducted for 49 clinical departments and outpatient nurses at Asan Medical center in Seoul. The survey consists of description questions to be able to express the intention of the individual and the questions made on the Likert 4 point scale. The main contents of 14 questions are composed of goodness of In Vitro laboratory and points to be improved. Results 62% answered that the best service in In Vitro laboratory was "good accuracy and reproducibility". On the other hand, as an inconvenience when requesting blood tests, 73% pointed out that "the result report time was long", which was recognized as a part to be improved. There are many contents that "The result of all tests is reported within 2 hours" on the day of the examination. In the question - 'Are there some examination results which do not coincide well with clinical observations?', 55 of 56 people answered "no". Above all, the majority answered that waiting for re-examination results is too long. This problem must be causing discomfort to the patients. Conclusion In order to improve these problems, the first thing is to increase the number of blood tests by using the current personnel, equipments and reagents to the fullest by item in Asan Medical Center's Nuclear medicine in vitro part. Secondly, in case of re-examinations, we use the "AMIS message" to show other clinical departments the reporting time. This methode improves the efficiency of work with nurses and increases satisfaction of custom service. Thirdly, the correlation was evaluated by selecting the test species that can be carried out by the shortening method. Currently, C-peptide and insulin are implemented in the reaction process to shorten 2 hours into 1 hour. Finally, we are considering purchasing new equipments for quick test results.

The purpose of this study is to investigate the mediating effect of learners" learning flow in the effect of presence on academic achievement in web-based e-learning. For this purpose, this study analyzed the influencing relationship between the each factor based on the structural model with the learning flow as a mediator variable. Based on existing theoretical studies, learning satisfaction and academic achievement, which represent learning outcomes, are set as dependent variables, and teaching presence, cognitive presence, and social presence are set as independent variables. Data collected from a total of 256 e-learning learners were used in the analysis of this study. According to the results of the analysis, teaching presence, cognitive presence, and social presence were found to have a significant effect on academic achievement when a learning flow is a mediator variable. Concretely, teaching presence, cognitive presence, and social presence have a positive effect on the learning flow, while learning flow has a positive effect on learning satisfaction. On the other hand, learning flow has a negative effect on academic achievement. As a result of verifying the mediating effect of learning flow on the relationship between presence, learning satisfaction, and academic achievement, there was meditating effect in the aggregate. This study implies that in order to increase the level of learning satisfaction and academic achievement, it is necessary to make the teaching-learning design in the provision of contents and materials for e-learning so that the learner can feel the presence. The results of this study can be used as a basic data for seeking support and promotion strategies for enhancement of future learning flow and presence.

저온 수성가스전이반응에서 $Cu/ZnO/MgO/Al_2O_3$ (CZMA) 촉매의 마그네슘의 영향을 조사하기 위하여 Cu/Zn/Mg/Al의 비율을 45/45/5/5 mol%로 공침법을 사용하여 제조하였다. 제조된 촉매들은 BET, $N_2O$ 화학흡착, XRD, $H_2-TPR$ and $NH_3-TPD$를 사용하여 분석되었다. 촉매 활성 테스트는 GHSV $28,000h^{-1}$와 온도 범위 $200{\sim}320^{\circ}C$에서 수행되었다. 동일한 조건에서 마그네슘이 첨가된 촉매(CZMA 400)는 가장 낮은 환원 온도를 나타내며 활성종인 $Cu^+$가 안정적으로 존재하고 또한 많은 약산점을 보유하였다. 또한 마그네슘이 첨가된 촉매(CZMA)는 마그네슘이 첨가되지 않은 촉매(CZA)와 비교하였을 때 240 이상의 높은 온도에서 촉매 활성이 증가하였다. CZMA 400 촉매는 최적의 촉매로서 $240^{\circ}C$, GHSV $28,000h^{-1}$에서 75 h 동안 활성의 저하없이 평균 CO 전환율 77.59%를 나타내었다. To investigate the effect of magnesium oxide addition, $Cu/ZnO/MgO/Al_2O_3$ (CZMA) catalysts were prepared using co-precipitation method with fixed molar ratio of Cu/Zn/Mg/Al as 45/45/5/5 mol% for low-temperature water gas shift reaction. Synthesized catalysts were characterized by using BET, $N_2O$ chemisorption, XRD, $H_2-TPR$ and $NH_3-TPD$ analysis. The catalytic activity tests were carried out at a GHSV of $28,000h^{-1}$ and a temperature range of $200{\sim}320^{\circ}C$. At the same condition, magnesium oxide added catalyst (CZMA 400) showed that the lowest reduction temperature and stable presence of $Cu^+$, that is active species and abundant weak acid site. Also magnesium oxide added catalysts (CZMA) showed higher catalytic activity at temperature range above $240^{\circ}C$ than the catalyst without magnesium oxide (CZA). Consequently, CZMA 400 catalyst is considered to be excellent catalyst showing CO conversion of 77.59% without deactivation for about 75 hours at $240^{\circ}C$, GHSV $28,000h^{-1}$.

Reaction characteristics and kinetics of a oxygen carrier (OCN717-R1SU) for chemical looping combustion (CLC) have been investigated using TGA by changing gas concentration (10-30 vol.% $CH_4$) and reaction temperature ($825-900^{\circ}C$). Reaction rate of OCN717-R1SU increased as temperature increased and it was found that reaction is delayed at the initial reaction regime. Johnson-Mehl-Avrami (JMA) model was adopted to explain the reaction phenomenon. The activation energy (E) determined by JMA model in reduction reaction of OCN717-R1SU is $151.7{\pm}2.03kJ/mol$ and pre-exponential factor and JMA exponent were also obtained. The parameters calculated in this study will be applied in design of the reactor and operation conditions for CLC process.

가와사키병 환아에서 면역글로불린 투여 전후의 혈중 Nitric Oxide와 Tumor Necrosis Factor-α에 대한 연구

박지혜,신지선,홍영미,Park, Ji Hye,Shin, Jee Seon,Hong, Young Mi 대한소아청소년과학회 2005 Clinical and Experimental Pediatrics (CEP) Vol.48 No.7

목 적 : 가와사키병은 면역 조절 인자의 이상을 동반하는 전신적 혈관염으로 관상동맥질환을 초래한다. NO는 혈관내 평활근의 granulocyte cyclase의 기전에 영향을 미쳐 혈관의 이완을 유발하는 역할을 하며 과다하게 분비될 경우 혈관의 변성을 초래하는 것으로 알려져 있다. 본 저자들은 가와사키병에서 NO와 $TNF-{\alpha}$의 혈중 농도를 측정하여 관상동맥질환 발생과 연관이 있는지 알아보기 위해 본 연구를 실시하였다. 방 법 : 가와사키병 환아 24명을 관상동맥 확장이 없는 군(1군)과 관상동맥 확장이 있는 군(2군)으로 분류하여 각 군의 임상 양상과 면역글로불린 투여 전과 후, 회복기에서의 NO, $TNF-{\alpha}$의 혈중 농도를 면역효소법(ELISA)으로 측정하여 비교하였다. 대조군으로는 같은 시기에 내원한 열이 없는 정상 대조군(3군) 13명과 열이 있는 대조군(4군) 10명으로 하였다. 결 과 : 면역글로불린 투여 전의 혈중 NO는 1군($13.2{\pm}5.7{\mu}mol/L$), 2군($20.4{\pm}10.7{\mu}mol/L$)과 4군($12.4{\pm}8.9{\mu}mol/L$)이 3군($3.1{\pm}1.4{\mu}mol/L$)보다 높았고 2군이 1군과 4군에 비해 유의하게 높았다(P<0.05). $TNF-{\alpha}$는 2군($858.4{\pm}934.0pg/mL$)에서 3군($8.7{\pm}2.3pg/mL$)과 4군($226.7{\pm}647.2pg/mL$)에 비해 유의하게 높았으며 1군($522.4{\pm}859.6pg/mL$)도 3군에 비해 높았다(P<0.05). 면역글로불린 투여 후 NO는 1군, 2군과 4군이 3군에 비해 유의하게 높았으며 $TNF-{\alpha}$는 각 군별로 유의한 차이가 없었다. 가와사키병 관상동맥 확장군과 비확장군 모두에 있어 NO와 $TNF-{\alpha}$의 혈중 농도가 면역글로불린 투여 전에 가장 높았고 면역글로불린 투여 후와 회복기로 갈수록 감소하였다. 또한 관상동맥 확장군에서 백혈구 수치와 혈청 NO는 유의한 양의 상관관계가 있었다(r=0.430). 결 론 : 가와사키병 환자에 있어 NO, $TNF-{\alpha}$의 혈중 농도가 유의하게 높았으며 NO의 농도가 관상동맥이 확장된 환자에서 비 확장군보다 의미있게 높은 것으로 보아 NO가 관상동맥질환에 관여할 것으로 생각한다. Purpose : Kawasaki disease(KD) is a systemic panvasculitis that causes coronary artery lesions. KD is accompanied by immunoregulatory abnormalities. Nitric oxide(NO) can induce relaxation of blood vessels by activating guanylate cyclase in smooth muscle cells and high levels of NO may result in coronary artery lesions. We investigated tumor necrosis factor$(TNF)-{\alpha}$ and NO production before and after intravenous immunoglobulin(IVIG) therapy to study the roles of NO and $TNF-{\alpha}$ in KD with coronary artery lesions. Methods : Serum levels of NO and $TNF-{\alpha}$ were measured in 24 patients with KD(group I, eight patients with normal coronary artery; group II, 16 patients with coronary artery lesions) and 23 controls(group III, 13 afebrile controls; group IV, 10 febrile controls). Blood samples from each subject were drawn before and after IVIG therapy and in the convalescent stage. Serum concentrations of NO and $TNF-{\alpha}$ were measured by enzyme linked immuno sorbent assay. Results : The NO levels before IVIG therapy were significantly higher in group II than in group I, group III and group IV. After IVIG therapy the levels of NO were significantly higher in group I and group II than in group III. The $TNF-{\alpha}$ levels before IVIG therapy were significantly higher in group I and group II than in group III. The serum $TNF-{\alpha}$ and NO levels were higher before IVIG therapy and decreased through the convalescent stage in KD patients. In the acute stage of KD patients with coronary artery lesions, serum NO levels significantly correlated with white blood cells (r=0.43, P<0.05). Conclusion : The serum concentration levels of $TNF-{\alpha}$ and NO were abnormally high in KD patients and NO concentrations were statistically higher in the KD patients with coronary artery abnormalities than those without coronary abnormality during the early stage of the KD. These results suggest NO may be involved in the development of coronary artery lesions.
