본 연구는 한국, 중국 등 극동아시아의 온대지역에서 재배되고 우리나라에서는 콩 다음으로 수요가 많은 팥 껍질(Phaseolus angularis shell)의 미백 효과를 검증하여 화장품 소재로서의 가능성을 확인하고자 하였다. 팥 껍질의 효능을 screening 하기 위하여 효소 실험인 tyrosinase 저해활성을 측정한 결과 1,000 ㎍/ml의 농도에서 76.39%의 저해활성을 나타내었다. 이후 멜라노마 세포의 생존율을 측정하여 팥 껍질이 세포에 독성을 미치지 않는 생존율 90% 이상의 농도에서 세포 실험을 진행하였다. 팥 껍질 추출물이 멜라닌 합성에 영향을 미치는 인자인 MITF, TRP-1, TRP-2, tyrosinase 단백질 및 mRNA 발현 억제 효과를 측정한 결과 모든 인자에서 발현량이 감소하였으며 대조군으로 사용된 kojic acid와 비교하였을 때 발현 정도가 유의하거나 더 감소한 것을 확인할 수 있었다. 이러한 결과, 팥 껍질 추출물의 미백 활성이 우수하다는 것을 확인할 수 있었으며 이는 미백 기능성화장품 소재로서 활용 가능성이 있을 것으로 사료된다. Whitening effect of the extract of Phaseolus angularis (PA) shell was investigated for its potential application as a functional ingredient for cosmetic products. The tyrosinase inhibitory effect, which is related to whitening, was 76.4% at a concentration of 1,000 ㎍/ml. Cell viability of melanoma cells was measured to test toxicity of the PA shell extract at concentrations showing at least 90% viability. In addition, western blot and RT-PCR assays of the PA shell extract showed concentration-dependent decreases of MITF, TRP-1, TRP-2 and tyrosinase protein and inhibitory effect of mRNA expression. These findings suggested that extract from PA shell has great potential as a cosmeceutical ingredient with whitening effect.

양육의 개념 분석

이수연,Lee Soo Yeon 한국아동간호학회 1998 Child Health Nursing Research Vol.4 No.1

Rearing is important to the growth and development of the child. Traditionally, nurturing is a maternal role which is expressive role. Maternal role was composed of mothering and maternicity. Rearing is a key concept of psychology, education and sociology discipline. Knowledge of the rearing is an essential component for the development of nursing as a science and a profession. The first thing to study a concept is thought to be a concept analysis. So, in this study, concept analysis of the rearing was performed to clarify a concept of the rearing as a basis for the study of rearing afterward. The approach used for the concept analysis was the approach presented by Walker and Avant (1993). The defining attributes of rearing, identified in this study were (1) a series of caring activities in parent-child relation, (2) an essential of the growth and development of a child, (3) changeable according to time, place and object, (4) effort is necessary to the rearing, (5) positive or negative aspects (6) attitude, behavior, environment is sub-concepts of the rearing concept. The identified antecedents of the rearing was child-birth. The identified consequences of rearing were desirable or undesirable outcomes. Desirable outcome was the emotional satisfaction and growth in parent-child relation. Undesirable outcome was the emotional disorder and social maladaptation of the child. The empirical referents of the rearing could be the caring phenomena in parent-child relation.

본 저자들은 경련과 의식저하를 보인 알레르기성 자반증 환아에서 신경학적 합병증으로 대뇌 동맥의 혈관염이 발생된 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Henoch-Sh${\ddot{o}}$nlein Purpura(HSP) is an immuologically mediated systemic vasculitis of small blood vessels affecting predominantly the skin, gastrointestinal tract, joints, and kidneys. Clinical neurological manifestations such as headaches, behavioral changes, mental changes, seizures, and visual loss are described, but neurological complication are rare during the course of HSP. We experienced a case of an 8 year-old male with HSP who presented with seizures. Magnetic resonance imaging(MRI) showed multiple high signal intensity in both cortical and subcortical areas of frontal and parieto-occipital lobes and magnetic resonance(MR) angiogram showed stenosis of cerebral arteries, compatible with MRI and MR angiogram findings of cerebral vasculitis. We report this case with related literature.

이수연,임소희,이대열,Lee Soo-Yeon,Lim So-Hee,Lee Dae-Yeol 대한소아신장학회 2003 Childhood kidney diseases Vol.7 No.1

목적 : 본 연구에서는 신반흔의 고위험 환아를 규명하고자 요로감염 후 DMSA 신주사를 이용하여 급성기와 치료 후 추적 검사를 통하여 신반흔을 형성한 군과 신반흔을 형성하지 않은 군에서 방광요관 역류 유무와 등급, DMSA 신주사 소견 등을 비교 분석하여 신반흔에 관련된 인자들을 평가하고 신반흔의 예측인자로서 방광요관 역류와 급성기 DMSA 신주사 소견의 유용성을 알아보고자 하였다. 방법 : 1992년 4월부터 2002년 3월까지 전북 대학교 병원 소아과에 요로감염으로 입원한 환아 442명을 대상으로 후향적으로 조사하였다. 요로감염의 급성기에 급성기반응 지표, DMSA 신주사를 시행하였고 치료 후 VCUG를 시행하여 방광요관 역류를 진단하였고 치료 4-6개월 후 DMSA 신주사를 시행하여 신반흔 유무에 따라 두 군으로 나누어 비교 분석하였다. 결과 : 연령 분포는 두 군 모두 1세 미만이 가장 많았으나 신반흔 형성군에서는 진단당시 연령이 신반흔 무형성군에 비해 높았고 성별에 따른 유의한 차이는 보이지 않았다. 원인균으로는 E.coli가 가장 많았으며 두 군간에 원인균에 따른 차이는 없었고 급성기에 시행한 백혈구, ESR, CRP 등의 급성기 반응지표는 신반흔 형성과 상관관계를 보이지 않았다. 신반흔 형성군에서는 방광요관 역류의 빈도가 78%, 신반흔 무형성군에서는 13%이었고, grade IV 이상의 중증의 역류가 차지하는 비율이 신반흔 형성군에서 높았으며 방광요관역류와 그 정도가 신반흔 형성과 밀접한 관계가 있음을 보여주었다. 급성기에 시행한 DMSA 신주사 소견상 다초점성 신피질 결손의 빈도가 신반흔 형성군에서 53%로 신반흔 무형성군의 32%에 비해 유의하게 높았고 방광요관 역류가 있으면서 신주사상 다초점성 결손을 보인 환아의 75%에서 신반흔이 형성되었다. 결론 : 신반흔 형성은 방광요관 역류의 유무와 정도, 급성기의 DMSA 신주사 소견과 밀접한 관계가 있었다. 따라서 초기 신주사 소견과 방광요관 역류는 신반흔 발생의 위험을 예측하는데 도움을 주며 고위험군으로서 추적관찰에 유용한 정보를 제공해 줄 것으로 생각된다. Purpose : Acute pyelonephritis in children may result in permanant renal damage which later in life may lead to hypertension and renal failure. The purpose of this study was to evaluate the factors that might be useful for predicting the development of renal scar in children with urinary tract infection(UTI). Methods : We retrospectively reviewed 442 patients with UTI who were admitted to the Department of Pediatrics of Chonbuk National University Hospital, during the period from April 1992 to March 2002. The patients were divided into two groups according to the presence of renal scar on the follow-up DMSA renal scan, and we compared the factors associated with renal scarring between the two groups. Results : There were no significant differences in sex, causative organism and acute phase reactants between the groups with and without renal scar. The age at diagnosis was significantly higher in the renal scar group compared to that without scar. Of the 60 patients with renal scar, 78% had vesicoureteral reflux(VUR), but 13% of patients without scar had VUR. Furthermore, the severity of VUR was significantly correlated with renal scar formation. 53% showed multiple cortical defects on the initial DMSA renal scan, compared to 32% in the non-scar group. In addition, 76% of patients showing multiple cortical defects on the initial DMSA renal scan with VUR had renal scar. Conclusion : The presence and grade of VUR, and findings on the initial DMSA renal scan would contribute to predict risk of renal scar formation in children with UTI.

이수연(Lee, Soo Yeon),박재국(Park, Jae Kook),박지우(Park, Ji Woo),안정은(An, Jeong Eun),이현정(Lee, Hyeon Jeong),김의명(Kim, Eui Myoung) 대한토목학회 2022 대한토목학회 학술대회 Vol.2022 No.10

정보통신기술의 발전과 건축기술의 발전으로 인해 실외공간에서 이루어지던 다양한 활동들을 실내에서 수행할 수 있는 환경이 되었으며, 이 때문에 실내공간에서 사용자에게 위치정보를 효율적으로 제공할 필요성이 높아지고 있다. 실외공간의 위치결정에 사용되는 GNSS는 실내공간에서 수신이 어려우므로 이를 대체하여 실내에서 활용할 수 있는 센서를 이용하여 위치 측위를 수행해야 한다. 이에, 본 연구에서는 Wi-Fi와 비콘을 이용하여 실내공간에서 위치 측위를 수행하고 보행 동선에 대한 정확도를 평가하였다.

굴과 상추에서 노로바이러스의 대체모델 feline calicivirus의 효율적 검출법 개발

이수연(Soo-Yeon Lee),장금일(Keum-Il Jang),우건조(Gun-Jo Woo),곽효선(Hyo-Sun Kwak),김광엽(Kwang-Yup Kim) 한국식품과학회 2007 한국식품과학회지 Vol.39 No.1

본 연구에서는 노로바이러스의 대체모델인 feline calicivirus(FCV)를 이용하여 식품 중에 존재하는 식중독 바이러스의 신속검출방법을 개발하였다. 일반적으로 식품 중에 존재하는 식중독 바이러스를 검출하기 위해서는 식품으로부터 바이러스를 분리시키고, 분리된 바이러스를 농축한 뒤 RT-PCR 방법을 이용하여 검출하는데, 각각의 과정을 수행하는 데 있어서 다양한 문제점이 존재하고 있다. 첫째, 식품으로부터 바이러스를 분리하고 농축하는 과정에서 시간이 많이 걸린다는 것과 둘째, 농축하여 추출된 바이러스 RNA로 RT-PCR 방법을 수행하는데 있어서 잔존하는 식품 성분이 PCR 반응을 저해하여 검출효율이 낮아지는 문제점이 있다. 본 연구에서는 0.2 ㎛ syringe filter를 사용하여 바이러스 분리과정에서 PCR 저해물질인 식품성분을 추가적으로 제거시켰으며, 농축과정에서는 분쇄된 얼음에 방치하는 방법을 사용하여 overnight하는 과정을 3시간으로 단축시켰다. 농축된 바이러스의 RNA 추출물에 잔존하는 PCR 저해물질을 희석함으로서 보다 높은 검출효율을 얻을 수 있었다. 본 연구를 통해 개발된 신속검출법은 굴과 상추에서 노로바이러스의 신속검출을 위한 방법으로 적용이 가능할 것으로 판단되며, 또한 다양한 식품에서 식중독 바이러스의 검출 효율을 향상시키는데 기여할 것으로 생각된다. Foodborne illness caused by Noroviruses (NVs) is increasing rapidly in Korea. This study developed an effective detection protocol for NVs found in contaminated oysters and lettuce through an investigation using the major steps of virus particle separation, concentration and RT-PCR. As a surrogate model for NVs, the cultivable feline calicivirus (FCV) that belongs to the same Caliciviridae family was used. Instead of using a time-consuming ultracentrifugation method, efficient methods based on solvent extraction and PEG precipitation procedure were applied. Direct homogenization of a 25 g sample of whole oyster and lettuce in 175 ㎖ PBS provided the simplicity that would be needed in the actual field of food product examination. The overnight PEG precipitation step at 4℃ was reduced to 3 h by placing the reaction tube in ice and by adjusting the PEG concentrations. The application of the use of chloroform and 0.2 ㎛ syringe filtration together showed a better detection efficiency than the use of chloroform alone in removing PCR inhibitors for both oyster and lettuce samples. Also, dilution of the extracted RNA solution before PCR provided increased sensitivity. The improved detection protocol developed in this study could be efficiently applied to detect FCV and most likely NVs from oysters and lettuce.

The purpose of this paper is to describe and explain the shortened words which are frequently used in Korean online community. They are not only used in spoken language but also in written language. They only used in online community and recently, shortened words are more widely used than before. In order to fine out the features of shortened words, we collected some examples in online parenting community, because they are many people who used the new-shortened words like ``음차(유모차), 얼집(어린이집), 셤니(시어머니)``. For analyzing the phenomena, this paper mainly dealt with two major fields. Firstly, we discussed the ways people make shortened words. Most of them are made by omitting non essential vowels or using syllable acronyms. Secondly, we surveyed users` language attitudes about the use of our examples Already mentioned, The words are often used in parenting community but other peoples who didn`t belong to that community didn`t know those and they have negative attitudes about those. So we can observed the relation of shortened words and in-group slang. Because of the difference in preference of new-shortened words, it can used as in-group slang.
