Electron Spin Resonance (ESR) spectroscopy has been used to detect the presence of radiation-induced free radicals in biological samples since the mid 1950s and to irradiate foods containing cellulose, crystalline sugar, and bone. Therefore, we analyzed the ESR spectrum of irradiated infant formula and its ingredients in this study. Samples were irradiated with 2 different radiation sources of 60Co gamma rays and electron beams (EBs), and the absorbed doses were 0, 1, 3, 5, and 7 kGy. ESR measurements were performed under normal atmospheric conditions using a JEOL JES-FA100 spectrometer equipped with an X-band bridge. Irradiated infant formula showed anunsymmetrical spectrum (g1=2.0050, g2=2.0006); in contrast, non-irradiated samples showed asymmetrical spectrum. The ingredients of irradiated samples showed a multi-component ESR signal in glucose and lactose and a singlet-type spectrum in milk powder (g=2.0050). R2 of the dose-response curve showed a fine linearity of over 0.95 across the entire sample. We also compared the spectra of identical samples irradiated with 60Co gamma rays and EBs, because EBs can be used for food irradiation in foreign countries, although this is not permitted in Korea. However, we could not find any significant differences according to the types of radiation source. Thus, ESR spectroscopy can be used to detect irradiated infant formula and several types of primary ingredients in this formula.

직접 PC슬래브설치를 통한 철도지하횡단 공법의 적용 연구
민경주(Min Kyung-Ju),이방우(Lee Bang-Woo),박병룡(Park Byung-Yong) 한국철도학회 2011 한국철도학회 학술발표대회논문집 Vol.2011 No.10
Existing grade crossings between railway and roadway area gradually changed to grade separation systems by the law. In the case of new roadway construction which crosses railways it shall be grade separation system in principle. With the railway underground crossing method many practices have been developed which can minimize rail displacements and avoid rail release. With these methods the effects to the train can be reduced. The underground crossing methods can be identified as open-cut methods and non open-cut methods. The open-cut methods include temporary support methods and special rail construction methods. Also the non open-cut methods includes pipe roof methods front jacking methods messer shield methods NTR methods and JES methods. Among these the most suitable method is applied considering safety economy class of each rail system (train passing frequency and velocity) etc. In the non open-cut methods the cost and duration shall be increased to keep existing rail system during construction. In the open-cut methods which use plate girders the rail speed shall be restricted due to the displacement and vibration of the girder. In this study new grade separation methods were developed. With this method the safety during construction can be increased. This method refines temporary support methods but pc slab girder with huge stiffness is applied instead of plate girders. With this method the rail displacement can be reduced and higher safety can be obtained during construction. Also construction cost and duration can be minimized because the temporary work and the overburden soil depth can be reduced.

경막외마취 환자에서 10% Pentastarch 용액의 혈장확장효과
이정은,박병룡,김은경,김만수,최세진 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.1
In order to compare the effect of 10 % pentastarch solution with Ringer's lactate solution on plasma volume expansion in thirty epidural anesthetic patients, systolic arterial blood pressure (SABP), diastolic arterial blood pressure(DABP), heart rate(HR), central venous pressure(CVP), cardiac output(CO) and changes of hemoglobin(Hb) were measured. The patients were devided into three groups Group Ⅰ (n=10) ; Epidural anesthesia was performed without fluid infusion previously(control) Group Ⅱ (n=10) ; 500 ml of Ringer's lactate solution was rapid infused intravenously before epidural anesthesia Group Ⅲ (n=10) ; 500 ml of 10% pentastarch solution was rapid infused intravenously before epidural anesthesia All data were collected before fluid infusion, at 15 min, at 30 min, at 45 min, at 60 min, at 120 min and at 180 min after epidural local anesthetic injection. The results are as follows. 1. SABP, DABP, HR, CVP and CO were decreased significantly (p<0.05) at 30, 45 minute after local epidural anesthetic injection in Group Ⅰ and Group Ⅱ. There was no any significant differences between two groups. 2. SABP, DABP, HR and CO were not changed significantly, Besides CVP was increased significantly (p<0.05) after 10% pentastarch solution infusion in group Ⅲ. 3. Changes of Hb were increased in group Ⅲ.
