AQP는 Stoltz(1997)가 개발한 역경지수 측정도구로 본 연구의 목적은 AQP의 신뢰도 및 타당도를 검증하는데 있다. 연구방법은 방법론적 연구로 상급종합병원 간호사(297명)대상으로 2013년 8월~10월까지 자료수집을 실시하였다.준거도구 로 Wagnild와 Young(1993)의 ResilienceScale을 이용하였고,분석방법으로 Cronbach’salpha계수,item totalcorrelation계 수,요인분석,상관관계분석,ANOVA test가 실시되었다.연구결과,전체 20문항의 Cronbach'sα 는 .840으로 나타났으며 KMO값(.804)과 Bartlett'stestofsphericity결과(χ2=2271.915,p=.000)에서 통계적 유의성을 보였다.요인 추출 결과,4개가 추출되었고,총 누적 변량은 56.256%였고 제1요인(개인의 통제력)10.7%,제2요인(개인의 주도성)13.7%,제3요인(상황의 영 향범위)17.4%,제4요인(상황의 지속성)이 14.9%의 설명력을 보였다.준거타당도 검증에서 준거도구와 양의 상관관계가 나타 났다.개인의 역경 극복력을 측정하는데 있어서 AQP가 보다 유용하게 활용될 수 있을 것으로 기대해본다. Stoltz's AQP is a tool to estimate the level of adversity. The purpose of study is to test the reliability and validity of AQP. The participants were 297 nurses of tertiary hospital in Korea. Data were collected from Aug. to Oct. 2013. Resilience Scale was used as criterion of AQP. Cronbach's alpha test, item total correlation, exploratory factor, correlation analysis, and ANOVA test were used. In result, factor analysis was accounted for four factors explaining 56.256% of total variance and corresponding factors were factor 1 (Control, 10.7%), factor 2 (Ownership, 13.7%), factor 3(Reach, 17.4%), factor 4 (Endurance, 14.9%). The internal consistency was acceptable (Cronbach's alpha=.84). Four factors were positively correlated with RS. AQP is a reliable and valid instrument to measure for adversity quotient in Korean nurse.

Derivation of primitive neural stem cells from human‐induced pluripotent stem cells
Shin, Woo Jung,Seo, Ji‐,Hye,Choi, Hyun Woo,Hong, Yean Ju,Lee, Won Ji,Chae, Jung Il,Kim, Sung Joo,Lee, Jeong Woong,Hong, Kwonho,Song, Hyuk,Park, Chankyu,Do, Jeong Tae John WileySons, Inc. 2019 Journal of comparative neurology Vol.527 No.18
<P><B>Abstract</B></P><P>Human‐induced pluripotent stem cells (hiPSCs) have facilitated studies on organ development and differentiation into specific lineages in in vitro systems. Although numerous studies have focused on cellular differentiation into neural lineage using hPSCs, most studies have initially evaluated embryoid body (EB) formation, eventually yielding terminally differentiated neurons with limited proliferation potential. This study aimed to establish human primitive neural stem cells (pNSCs) from exogene‐free hiPSCs without EB formation. To derive pNSCs, we optimized N2B27 neural differentiation medium through supplementation of two inhibitors, CHIR99021 (GSK‐3 inhibitor) and PD0325901 (MEK inhibitor), and growth factors including basic fibroblast growth factor (bFGF) and human leukemia inhibitory factor (hLIF). Consequently, pNSCs were efficiently derived and cultured over a long term. pNSCs displayed differentiation potential into neurons, astrocytes, and oligodendrocytes. These early NSC types potentially promote the clinical application of hiPSCs to cure human neurological disorders.</P>

옥수수수염 차의 MPSS 처리에 의한 위해미생물의 살균 효과에 대하여 연구하였다. 옥수수수염 차에 E. coli와 L. monocytogenes를 5~6 log CFU/㎖ 수준으로 접종하고, MPSS 처리한 후 25℃에서 12일 동안 저장하면서 실험하였다. E. coli는 1, 2, 3 회 MPSS 처리 후 각각 1.14, 2.49, 5.72 log CFU/㎖의 감균 효과를 보였고, L. monocytogenes는 MPSS 1, 2, 3회 처리 후 각각 1.93, 4.49, 6.62 log CFU/㎖의 감균 효과를 보였다. 또한, E. coli와 L. monocytogenes 모두 MPSS 4회 처리 후에는 모두 사멸되었고, 저장 12일까지 검출되지 않았다. 그리고 MPSS 처리는 옥수수수염 차의 TPC 에 부정적인 영향을 끼치지 않았고, 탁도는 4회 이상 MPSS 처리에 의해 향상되었다. 따라서 본 연구 결과, MPSS 처리는 옥수수수염 차의 품질 유지와 더불어 미생물 생육 억제가 가능하기에 옥수수수염 차의 살균에 MPSS를 적용할 수 있다고 판단된다. Inactivation of foodborne pathogenic bacteria in corn silk tea was evaluated using a microwave plasma sterilization system (MPSS). Corn silk tea was inoculated with Escherichia coli and Listeria monocytogenes, treated with an MPSS treatment, and stored at 25℃ for 12 days. The one, two, and three cycles of treatment with MPSS reduced the population of E. coli by 1.14, 2.49, and 5.72 log CFU/㎖, respectively, compared to that of the control. In the case of L. monocytogenes, one, two, and three cycles of MPSS treatment reduced the population by 1.93, 4.49, and 6.62 log CFU/㎖, respectively. Both E. coli and L. monocytogenes were eliminated within four cycles of treatment with MPSS, and even after 12 days of storage, the bacteria were not detected. Total polyphenol content in the corn silk tea did not change much among treatments, and turbidity of the corn silk tea improved following four cycles of MPSS treatment. These results suggest that MPSS treatment can be useful for improving the microbial safety and quality of corn silk tea during storage.
