본 연구에서는 현재 임상에서 home bleaching을 위해 사용되고 있는 표백 재료들이 치아 법랑질의 투명도에 어떠한 변화를 일으키는지 고찰해 보고자 시행하였다. 실험 대상으로는 하루 전 발거한 우치 (bovine tooth)를 사용하였다. 치아의 순면에 수직되게 다이아몬드 드릴을 이용해 수주 하에서 직경 6 mm의 원통형 치아 시편을 만들어 순면이 노출된 상태로 투명한 아크릭 레진에 포매한 후, low speed diamond saw (Isomat, Buehler Co., USA)를 사용하여 1.2 mm 두께로 절단하였다. 절단된 시편은 순면을 먼저 편평하게 연마하고,절단된 면을 연마하여 두께 1 mm의 시편을 완성하였다. 완성된 시편(우치 25개)을 무작위로 추출하여 3개의 그룹으로 나누고 나머지는 대조군으로 하였다. Opalescence (10% carbamide peroxide, Ultradent, Milford, USA), Rembrandt (10% carbamide peroxide, DenMat, USA) 및 Opalescence F(15% carbamide peroxide with fluoride, Ultradent)를 시편의 순면에 1주일 동안 적용 (표백제는 24시간마다 교체)하였고, 설측면은 증류수를 적신 거즈에 접촉된 상태로 보관하였다 표백제를 적용하기 전과 적용 3, 5, 7일째에 시편의 삼자극치 X, Y, Z 값을 색채색차계 (Color & Color Differencemeter, Model TC-6FX, Tokyo Denshoku Co., Japan)로 백색 배경판과 흑색 배경판 상에서 측정하였다 백색 배경판과 흑색 배경판 상에서 측정된 Y값의 평균값을 이용해 contrast ratio를 계산하였다 얻어진 값을 One Way Repeated Measured ANOVA를 이용하여 통계 처리한 결과 10% Opalescence처치군, 15% Opalescence-F처치군 및 대조군에서는 통계적으로 유의할만한 증감을 보이지 않았고, Rembrandt처치군에서는 Contrast ratio가 증가하였다 (p < 0.01) . This study was done to evaluate whether vital bleaching agents could influence on the translucency of the bovine enamel. The anterior bovine teeth that were extracted one day before and without any gross discoloration were obtained and then were preserved in physiologic saline. 6 mm cylindrical tooth specimens were fabricated with diamond puncher perpendicularly on labial surface of bovine tooth. After embedded in transparent acrylic resin with labial surface being exposed, they were cut to a thickness of 1.2 mm with low speed diamond saw (Isomat, Buehler Co., Lake Bluff, IL, USA). They were smoothly ground to 1 mm thickness of enamel with sandpaper. 24 specimens were randomly divided into 3 groups and control group respectively. Opalescence (10% carbamide peroxide, Ultradent, South Jordan, USA), Rembrandt (10% carbamide peroxide, DenMat, USA) and Opalescence F (15% carbamide peroxide with fluoride, Ultradent, USA) were applied on labial sides of the bovine enamel for 7 days (bleaching agents were reapplied every 24 hours) and the opposite surface was contacted to cotton that soaked in distilled water. The control group was soaked in distilled water. Three stimulus value X, Y and Z were evaluated with colorimeter (Color ' Color Differencerneter, Model TC-6FX, Tokyo Denshoku Co., Japan) on the labial surface of all specimen three times on white and black background plate before the bleaching agents were applied and on 3rd, 5th and 7th day after applied. The degree of translucency was normally assessed by measuring the inverse property, opacity (contrast ratio). 10% Opalescence, 15% Opalescence-F, and control group showed no significant variation in the translucency of bovine enamel, However Rembrandt decreased the translucency of it (p < 0.01).

The objective of this study is to predict the high risk group of coronary artery disease from body mass index, blood pressure, fasting blood sugar and serum lipids level using the method of discriminant analysis. Variables with significant difference between coronary artery disease group and normal group were HDS-C, LDL-C/HDL-C, LDL-C, and TG. But the acuity did not exceed 70% in any single variable. As the results of discriminant analysis, statistically significant discriminant variables were HDL-C, T-chol, FBS and TG. The discriminant equation was(Y) = -0.06759(HDL-C) + 0.01498(T-chol),+0.01923(FBS) - 0.01421(TG) + 0.5187, and the overall discriminant power using the above 4 variables was 79.3%

Ju‑Won Park,Howook Choi,Hwangsun Kim,Simoon Sung,Hye‑Jin Jeong,Il Kim,Jaeseok Gong,Sung‑Tae Hong,Heung Nam Han 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.5

The effect of high electric current density on the sintering of Ag wires manufactured by screen printing is evaluated throughelectrical resistivity analysis and microstructure observation. Different forms (continuous and pulsed) of electric currentwith different current densities are applied to the specimens. Conventional heat treatment is also performed as a controlgroup to examine the athermal effect of electropulsing treatment. Compared to the conventional heat treatment, the resistivityis reduced more under the electropulsing treatment with continuous current for the same temperature and treatment time.Also, the process time of electropulsing treatment can be reduced by applying a pulse form of high density current insteadof continuous current without losing the benefit of enhanced reduction of resistivity. The microstructural observationsobtained from high angle annular dark field scanning transmission electron microscope and a digital precession instrumentclearly show that necking connecting the crystals is formed more firmly under electric current. In addition, the temperaturechange of Ag wire and substrate is calculated according to the change of the resistivity when the electric current is appliedto confirm the reliability.

섬유성 골이형성증은 비정상적인 섬유성 골조직으로 대체되며 느리게 진행하는 골병변이다. 섬유성 골이형성증과 부갑상선기능항진증은 흔하게 관찰되는 질환이나 McCune-Albright 증후군 없이 일차성 부갑상선기능항진증에 동반된 섬유성 골 이형성증은 거의 보고된바가 없다. Tc-99m MDP 골스캔이 섬유성 골이형성증의 진단에 유용하다고 알려져 있으나, Tc-99m MIBI 영상은 아직 보고된 바가 없다. 저자들은 McCune-Albright 증후군이 없이 부갑상선기능항진증에 동반된 섬유성 골 이행성증의 Tc-99m MIBI 스캔과 Tc-99m MDP 골스캔의 영상을 비교하였다. Tc-99m MDP 골스캔상 병변 부위에서 증가된 섭취 소견을 보였으며, Tc-99m MIBI 조기영상에서도 동일한 위치에서 섭취증가가 관찰되었다. 2시간 지연 Tc-99m MIBI 영상에서는 Tc-99m MIBI의 섭취가 배출되는 소견을 보였다. 섬유성 골이형성증 병변에서 Tc-99m MIBI 스캔이 유용할 것이라고 생각하며, 섬유성 골이형성증 병변에서 Tc-99m MIBI의 섭취를 증가시키는 인자에 대한 더 많은 연구가 필요할 것으로 생각한다.

김주원(Ju Won KIM),김용준(Yong June KIM) 한국무역상무학회 2015 貿易商務硏究 Vol.66 No.-

This research is, first of all, a theoretical study concerning 'conflict.' Only then, we could obtain ways in which we manage and resolve various problems arising fromconflicts in business between Korean and Chinese companies. In doing this, we also tried to grasp cultural characteristics, or factors, in Chinese ways of carrying out negotiations that lead to conflicts with us. On the basis of these preliminary considerations, we developed practical techniques of conflict management and types of negotiation strategy. We thereby could suggest broader strategic implications for better performance in international business. Concretely, this research investigates techniques of conflict management and types of negotiation strategy. For such techniques and types, we suggest, (1) Sharing technique or reconciliatory compromising negotiation and its compromise strategy, (2) collaborative technique or cooperative negotiation and its win-win strategy, (3) competitive technique or competitive negotiation and its profit-seeking attack strategy, (4) accommodative technique or receptive negotiation and its relation-maintaining yield strategy,(5) avoidant technique or evasive negotiation and its indifference-showing avoidance strategy. This research contributes to promote understanding on negotiation culture of chinese corporate. and we provide the guideline of the conflict management and the insight for the efficiency strategy of chinese business negotiation. But, empirical data and statistical examinations should be added to our present research for the future prospective ones.

1996년 6월 카톨릭대학교 부천성가병원에 뇌경색으로 입원했던 61세 남자 환자의 혈액에서 Flavobacterium meningosepticum을 분리하였다. 환자는 폐렴을 동반한 패혈증의 예로 ceftriaxone과 metronidazole을 투여하였으나 입원 48시간만에 사망하였다. Flabovacterium meningosepticum is a rae cause of nosocomial infection which shows multi-drug resistance. It mainly invades patients with impaired immunity. Recently, we experienced a case of F. meningosepticum bacteremia in a patient with chronic debilitated state owing to stroke. The clinical progress was so rapid that he died within 48 hours. Blood culture revealed F. meningosepticum which showed characteristic yellow colony in blood agar plate.

박상원,김동우,박주원,이순일,신영학,김의종,오명돈,최강원 대한감염학회 2005 감염과 화학요법 Vol.37 No.2

삼일열 말라리아는 국내에서 재유행하고 있는 감염질환으로, 일반적으로 양성의 임상경과를 거친다. 저자들은 특이한 질병력이 없이 건강하였던 젊은 성인이 국내에서 삼일열 말라리아에 걸린 후 다기관기능부전과 폐출혈으로 사망한 증례를 경험하였다. 환자의 중증 임상경과를 설명할 만한 특이한 인자가 발견되지 않았다. Vivax malaria is a re-emerging infectious disease in Korea with cumulating 19,416 cases as of December 2003 since 1993. Vivax malaria is generally a benign disease with few severe complications. Even in the worldwide literature, there are only small number of case reports on severe complications. We experienced a fatal vivax malaria in a previously healthy young adult with severe multi-organ failure and fatal massive pulmonary hemorrhage. The patient presented with abdominal pain and shock. There were splenic hemorrhage, disseminated intravascular coagulation, oliguric acute renal failure requiring dialysis, and pulmonary hemorrhage leading the patient finally to death. The initial parasitemia was 2,046/μL. Thin smear and PCR revealed only Plasmodium Vivax. There was no explainable cause of death except for the only serological suggestion of Mycoplasma pneumoniae infection without correlating clinical evidence. This is a first case of fatal vivax malaria in Korea since its re-emergence in 1993. Further case monitoring is needed to define whether this is a index case or an isolated one.

Purpose: The purpose of this study was to identify the relationships among trait anger, anger expression, job satisfaction, job commitment, and organizational performance, and especially to verify the effect of anger experience on organizational performance. Method: A descriptive study was conducted using a convenient sample. Data were collected by a self-report questionnaire from 671 clinical nurses in three university hospitals and analyzed by using SPSS 14.0 Win program with descriptive statistics, t-test, ANOVA, pearson correlation coefficient, and stepwise multiple regression. Result: Organizational performance was significantly correlated with trait anger, anger expression-in, anger expression-out, anger control, job satisfaction, and job commitment. Multiple regression analysis showed that organizational performance was significantly predicted by job commitment, job satisfaction, educational level (university graduation), anger control, and working place (operative room), and 34.7% was explained by these variables. Conclusions: Out of anger expression, anger control significantly affected on organizational performance together with job commitment and job satisfaction. From this result, it could be concluded that nursing intervention for anger control have a positive effect on improving organizational performance. Further studies are needed to develop and test the effect of nursing intervention programs for anger control.
