Perfluorinated sulfonic acid (PFSA) ionomers have been used as polymer electrolyte membrane (PEM) materials owing to their excellent chemical durability and proton conductivity. However, the PFSA ionomers are suffering from fast hydrogen crossover and, thereby, chemical degradation in the membrane state. To solve these issues is to make reinforced membranes by filling proton-conductive PFSA ionomers in the pores of chemically robust poly(tetrafluoroethylene) (PTFE) support films. However, it is very difficult to obtain PFSA-PTFE reinforced membranes with improved hydrogen barrier property. In this study, PFSA-PTFE reinforced membranes were fabricated by immersing commercial reinforced membrane in PFSA ionomer dispersions with different chemical architectures and particle sizes and their effects were systematically investigated.

Inactivation Kinetics of Listeria innocua ATCC 33090 at Various Temperature Heating-up and Pressure Building-up Rates

안주희,V.M. Balasubramaniam 한국식품과학회 2007 Food Science and Biotechnology Vol.16 No.2

The effects of temperature heating-up rate and pressure building~up phase on the inactivation of Listeria innocua ATCC 33090 were evaluated in buffered peptone water. The number of 1. znnocua was reduced by 5.57 and 6.52 log CFUI mL during the nonisothermal treatment (the come-up time followed by isothermal process) and i?e Isothermal treatme~t, res ectivel at 60°C. When compared to the isothermal treatment (0.76<D value<0.9?), 1. znn~cua. exposed at t e no~sothe~al treatment (1.58<D value<2.31) became more resistant to heat. The come-up tune r~ductIons m numbers of 1. innocua significantly increased with increasing the heating rates (p<0.05). The pronounced ~eductI?n was observed by more than 5 log CFU/mL at 33.2°C/min of temperature heat!ng-~ate. T.he effect of the combmed high pressure and thermal processing on the inactivation of 1. innocua increased WIth mcreas~g pressure and temperature. ~t all temperature levels from 40 to 60°C under 700 MPa,1. innocua was not detected by ennchment culture (>7 log reduction).

안주희,이현용,Lynn Knipe,V.M. Balasubramaniam 한국식품과학회 2014 Food Science and Biotechnology Vol.23 No.5

Effects of surface pasteurization on inactivationof Listeria innocua were investigated. Surface temperature,monitored during post-packaging pasteurization, was usedto predict the lethality of L. monocytogenes. Temperaturesreached 70oC for lean and fat sausages within 9 min oftreatment. An inoculation study validated the efficacy ofpost-processing and the thermal lethality of L. monocytogenes. Pre-cooked sausage and ham, inoculated with approximately107 CFU/cm2 of L. innocua, were heated to a surfacetemperature of 70oC. Numbers of L. innocua were reducedby 7 log on surface-inoculated sausage. Guidelines for safe,ready-to-eat meat products are provided for small scalemeat processors.

Inactivation Kinetics and Injury Recovery of Bacillus amyloliquefaciens Spores in Low-acid Foods during Pressure-assisted Thermal Processing

안주희,Bala V. M. Balasubramaniam 한국식품과학회 2014 Food Science and Biotechnology Vol.23 No.6

Pressure-assisted thermal processing (PATP)inactivation kinetics of Bacillus amyloliquefaciens sporesin deionized water (DIW) were evaluated for egg pattymince (EPM) and green pea puree (GPP). Recovery ofPATP-injured spores during storage was determined. Thenumber of B. amyloliquefaciens spores in DIW wasreduced more than 6 log when treated at 121oC and 700MPa, including a come-up time reduction (3.32 log MPN/g) and a pressure holding time reduction (3.55 log MPN/g). Treatments at 700 MPa in combination with 105oC for16 min, 115oC for 5 min, or 121oC for 3 min, decreasedB. amyloliquefaciens spore populations in EPM to levelsundetectable using an enrichment procedure. No significant(p>0.05) recovery of PATP-injured spores was observed inEPM and GPP during storage for 8 weeks, compared withcontrols. These results provide useful information forenhancing microbial lethality of PATP-resistant bacterialspores in low-acid foods.

안주희,곽승주 한국열린유아교육학회 2017 열린유아교육연구 Vol.22 No.1

The purpose of this study was to grasp the private education status of infancy consequent on the private education type, and to look into the difference in perception of private education between teachers and parents. To this end, this study analyzed data targeting 235 parents with children aged between 0 and 36 months living in Gyeonggi-do Province, and 206 child care teachers with careers conducting infant classes. Results are as follows. First, special activities at day care centers were the most common type for infants, followed by private institute education, and home-visiting education in actual condition of experience by private education type. Also, it was found that private institute education and special activities at day care centers were developed with a focus on physical activity while home-visit education was developed with a focus on language and math activity for learning preparation. Second, results revealed a difference in private education between parents and teachers, namely that both parents and teachers perceived the private education of infancy as irrational exuberance; the reply ‘in order not to fall behind the same age group’ was found to be the highest. Also, as regards the private institute education among the private education types, teachers, much more than parents, felt that an infant’s participating period was much too early. As regards home-visiting education, both parents and teachers were found to perceive it as unsuitable for activity of infancy, whereas both parents and teachers perceived the special activity at a day care center as necessary. 본 연구는 사교육 유형에 따른 영아기 사교육 현황과 실태를 파악하고 사교육에 대한 교사와 부모와의 인식차이를 살펴보는 데 그 목적이 있다. 이를 위해 경기지역의 만 0~36개월 미만 자녀를 둔 부모 235명과 영아반 경력이 있는 보육교사 206명 총 441명을 대상으로 자료를 분석하였다. 연구결과 첫째, 사교육 유형별 경험 실태는 특별활동을 경험한 영아들이 가장 많았으며 다음으로 사설기관교육, 가정방문교육 순으로 나타났다. 사설기관 교육과 어린이집 특별활동은 신체활동을 위주로, 가정방문교육은 학습준비를 위한 한글․수 활동 중심으로 전개되고 있었다. 둘째, 사교육에 대한 부모와 교사의 인식차이를 분석한 결과, 영아기 사교육 대하여 부모와 교사 모두 과열현상이 있다고 인식하고 있었으며 그 이유로는 ‘또래보다 뒤떨어지지 않게 하기 위해서’라는 응답이 가장 높게 나타났다. 또한 사교육 유형 중 사설기관교육에 대해 부모보다 교사가 영아의 참여시기가 너무 빠르다고 인식하였다. 가정방문교육은 부모와 교사 모두 영아기 활동에는 적절하지 않으며, 어린이집 특별활동은 부모, 교사 모두 필요하다고 인식하였다.

SPAE (Sulfonated poly(arylene ether sulfone), SPAES) copolymers exhibit a lot of advantages such as a relatively low production cost, and easy control of ionic conductivity and gas barrier properties, when they are used as membrane materials for polymer electrolyte fuel cells, redox flow batteries, and electrolysis. SPAES copolymer membranes are fabricated by evaporating polar aprotic solvents from their concentrated solutions. This conventional process, however, is needed to be excluded, owing to additional production cost associated with the organic solvent separation and hazardous issues. In this study, a benign membrane fabrication method is developed based on SPAES nanodispersions in water-alcohol mixtures. Their fundamental characteristics are systematically investigated in comparison with those made from the conventional method.

소아 참여 임상시험에서 부모의 임상시험의 이해도와 설명만족도

안주희,윤영란,나연경,홍해숙 한국의료윤리학회 2016 한국의료윤리학회지 Vol.19 No.1

본 연구는 소아 참여 임상시험에서 소아의 부모를 대상으로 임상시험에 대한 이해도와 설명만족도를 조사하고 그 관련요인을 확인하기 위한 서술적 조사 연구이다. 광역시에 소재한 일개 대학교병원 소아청소년과에서 임상시험에 참여한 소아의 부모 41명을 대상으로 자가보고식 설문지를 이용하여 자료수집하였고, 수집된 자료는 SPSS Statistics 20을 이용하여 기술학적 통계와 Mann-Whitney U test, Kruskal-Wallis test와 Spearman의 순위 상관분석을 하였다. 연구 결과 임상시험 이해도는100점 만점에 평균 71.1점으로 가장 이해도가 높은 항목은 개인적 이득으로 84.3점, 가장 낮은 이해도를 보인 항목은 위험성에 대한 보상부분으로 40.9점으로 나타났다. 임상시험 이해도는 연구자의 임상시험 설명에 소요된 시간(p=.045)과 연구자로부터 임상시험 설명을 들은 후 느끼는 난이도 정도(p=.033)에 따라 유의한 차이가 있었다. 임상시험 설명만족도는 100점 만점에 73.6점이였고, 임상시험 이해도와의 상관관계에서 양의 상관성(p<.001)을 보였다. 결론적으로 임상시험 이해도와 설명만족도를 높이기 위해서 연구자는 부모가 이해하기 어렵고 더 자세한 설명이 필요한 항목들을 확인하고, 소아 임상시험 설명과정에서 충분한 시간을 할애하고, 대상자의 수준에 맞는 용어를 사용하여 설명해야 한다. The purpose of this study was to assess parents’ understanding of, and satisfaction with, the explanations provided by researchers conducting pediatric clinical trials. Self-report questionnaires were collected from forty one parents of children treated at a national university hospital in South Korea. A Mann-Whitney U test, Kruskal-Wallis test, and Spearman correlation test were performed on the collected data using SPSS Statistics 20.0. The mean for understanding was 71.1 points out of 100. The item that was best understood was collective benefit (84.3 points); the item that was least understood was compensation for risk (40.9 points). The predictors of understanding were the explanation time of the researcher (p=.045) and the feelings of difficulty with the researcher’s explanation (p=.033). The mean for explanation satisfaction was 73.6 points and was related to understanding (p<.001). The results of this study suggest that researchers in pediatric clinical trials should identify items that parents are likely to find difficult to understand, spend sufficient time explaining procedures to parents, and match the level of the explanations they offered to individual parents’ general level of understanding.
