Purpose: The mean adult height of Koreans has increased since nationwide anthropological measurements began in 1967. The objective of this study was to evaluate differences in heights of Korean late adolescents and young adults within and between the Second and Fifth Korea National Health and Nutrition Examination Surveys (KNHANES II and V). Methods: Koreans aged ${\leq}22$ years with available measurements of height were enrolled from the KNHANES surveys (KNHANES II: n=3,372 [1,732 males and 1,640 females]; KNHANES V: n=6,190 [3,198 males and 2,992 females]). Differences in the height of KNHANES respondents within and between surveys were evaluated according to age and sex. Results: In KNHANES II, there was no significant difference in height between males aged 17-19 years and those aged 20-22 years ($174.3{\pm}0.5cm$ vs. $174.3{\pm}0.6cm$, P=0.995). Females aged 20-22 years were taller than those aged 17-19 years ($159.8{\pm}0.4cm$ vs. $161.0{\pm}0.4cm$, P=0.017). Females aged 17-19 years were significantly taller in KNHANES V than in KNHANES II ($161.2{\pm}0.3cm$ vs. $159.8{\pm}0.4cm$, P=0.004). Respondents aged 20-22 years were taller in KNHANES V than in KNHANES II, although not significantly so; the difference was $0.3{\pm}0.8cm$ in males (P=0.721) and $0.5{\pm}0.6cm$ in females (P=0.386). Conclusion: Koreans appear to continue growing even in their late adolescence and early twenties. Consequently, it may be necessary to expand the reference age ranges of the Korean growth chart. Additionally, a longitudinal growth survey is needed to determine growth patterns and secular trend in height among Koreans.

김주옥(Kim, Ju-Ok),류언나(Ryoo, Eon-Na),하은호(Ha, Eun-Ho) 한국산학기술학회 2012 한국산학기술학회논문지 Vol.13 No.4

본 연구는 도시노인의 외로움 정도와 영적 요구를 파악하고 이들의 관련성을 규명함으로써 심리적인 건강과 영적 건강에 대한 이해를 증진시키고, 영적 돌봄의 필요성을 재확인하여 간호사의 역할 확대 및 노인전문간호사 역할 확립에 기여함은 물론 도시지역 경로대학의 건강 관련 교육프로그램 또는 영적 돌봄 프로그램 개발의 기초자료를 제 공하기 위해 실시하였다. 연구대상은 서울시 K구에 거주하면서 S교회 경로대학에 다니고 있는 65세 이상의 노인으로 서 의사소통이 가능하고 본 연구에 동참하기를 수락한 노인 159명으로 하였다. 연구결과 대상자의 외로움 정도는 평 균 2.02점(4점 만점)이었으며, 영적 요구는 평균 4.51점(5점 만점)으로 조사되었고 사랑과 유대감 영역이 가장 높았다 (4.66). 외로움과 영적 요구는 역 상관관계가 있어서(r=-.31, p<.001) 외로움이 클수록 영적 요구도는 낮았고 종교 예식 에 참여하는 경우(p=0.032), 80세 이상 생활보조금을 받는 여성의 영적 요구가 높은 것으로 나타났다. 그러므로 노인 들의 외로움을 감소시키기 위한 영적 간호중재 전략이 필요하다. The purpose of this study was to identify the loneliness and spiritual needs of the elderly in a certain area. The participants in this study were over 65 years, 159 elderly who attended in senior classes in Seoul. The instruments used for this study were revised UCLA 'Loneliness scale' developed by Russell, Peplau & Cutrona (1980) and translated by Kim & Kim (1989) and 'Spiritual need scale' developed by Yong (2008). The collected data were analyzed using SPSS 15.0 program, t-test, ANOVA, Scheffe's test and Pearson's correlation coefficient. The score of loneliness was 2.02/4, spiritual need was 4.51/5. The relationship between loneliness and spiritual needs showed significant negative correlation. Loneliness of the elderly who do not attend a religious attendance was high and spiritual needs were low. Spiritual needs of the elderly who are women over 80 years and living with subsidy from the government were high. Spiritual nursing interventions are needed to reduce a feeling of loneliness among the elderly who experience high degree of loneliness.

추출 방법에 따른 명일엽과 돌미나리 착즙박의 정미성분 및 항산화 특성

이현정,유하나,이현규,Hyun Jung Lee,Ha Na Ryoo,Hyeon Gyu Lee 한국식품위생안전성학회 2023 한국식품위생안전성학회지 Vol.38 No.6

본 연구에서는 추출 수율 및 소재의 풍미를 높일 수 있는 EE와 CE를 통해 명일엽과 돌미나리 착즙박 추출물을 제조하여 추출물의 정미 성분인 유리아미노산, 유기산, 당류와 항산화 특성인 DPPH 라디칼 소거능, TPC, TFC를 비교분석하여 명일엽과 돌미나리 착즙박 추출물의 업사이클 가능성을 검토해 보고자 하였다. 유리아미노산의 함량은 명일엽 착즙박은 EE가, 돌미나리 착즙박은 CE가 더 높은 추출 효율을 가졌으며, 착즙 전 원물로 제조한 추출물에 비해 높은 추출 효율을 나타냈다. AKEE의 주요 아미노산은 leucine, alanine, aspartic acid, AKCE의 주요 아미노산은 valine, alanine, aspartic acid 이다. OJEE의 주요 아미노산은 leucine, aspartic acid, arginine, OJCE의 주요 아미노산은 valine, aspartic acid, arginine으로 추출물의 특성에 맞게 사용한다면 식품의 풍미 향상과 더불어 기능성 소재로의 활용 가능성을 확인할 수 있었다. 유기산과 당류 함량은 명일엽, 돌미나리 착즙박 공통적으로 CE의 추출 효율이 높았다. 추출방법에 따라 유기산 및 당류의 조성이 상이하기 때문에 신맛과 단맛의 패턴이 다르게 나타나며 산도 조절과 같은 기능적 특성도 예상할 수 있다. DPPH 라디칼 소거능과 TPC 함량은 명일엽, 돌미나리 착즙박 공통적으로 CE의 추출 효율이 높았다. 이는 CE에 사용한 에탄올과 페놀성 화합물이 반응하여 추출 함량이 증대 된 것으로 판단된다. 또한, 폴리페놀 함량이 높아질수록 DPPH라디칼 소거능이 높아지고 있어 양의 상관관계 성립을 예측할 수 있었다. 하지만 착즙 전 원물 추출물 대비 착즙박 추출물의 항산화능은 다소 낮은 수준이므로 사용량에 대한 검토가 필요하다. TFC 함량은 명일엽 착즙박 추출물은 CE 대비 EE 에서 더 높은 추출 효율을 가지지만, 돌미나리 착즙박 추출물에서는 EE와 CE의 통계적 유의성이 없게 나타났다. 이는, 착즙박 추출물에 가해진 효소의 활성 조건이 착즙박의 세포벽 결합 구조를 파괴하여 플라보노이드의 추출을 유도할 때 AKEE에서는 적합하였지만, OJEE에서는 부적합하여 다른 경향의 결과를 나타내는 것으로 유추해 볼 수 있다. 본 연구를 통하여 명일엽과 돌미나리 녹즙 제조 후 생성되는 착즙박을 활용한 추출물의 정미 성분과 항산화 특성을 분석하였고 고부가가치 소재의 이용성 가능성을 확인 할 수 있었다. 연구결과를 바탕으로 실용화를 위한 구체적 연구개발의 확대가 필요할 것으로 사료된다. This study aimed to examine the possibility of upcycling extracts of Angelica keiskei and Oenanthe javanica juice by-products through comparing enzyme extraction (EE) and complex extraction (CE) methods to increase the extraction yield and flavor of materials. A higher extraction yield was obtained for free amino acid content with EE and CE for A. keiskei and O. javanica juice by-products, respectively, and a higher extraction efficiency was achieved with juice by-products than with extracts prepared from raw materials before juice production. The content of major amino acids varied depending on the extraction method used. When used according to the characteristics of the extract, their use as a functional material was confirmed along with improvement in the flavor of the food. Consistently high extraction yields for organic acid and sugar levels were obtained with CE in A. keiskei and O. javanica juice by-products. The DPPH radical scavenging ability and TPC were consistently high with CE in A. keiskei and O. javanica juice by-products; the increase in extracted content was likely because of the reaction between the ethanol used for CE and the phenolic compounds. However, because the antioxidant capacity of the juice by-product extracts was somewhat lower than that of the extracts from raw materials before juice production, the amount used should be reviewed. The TFC was found to be higher in extracts obtained with EE than with CE for A. keiskei juice by-products; however, no significant difference was observed between EE and CE in the O. javanica juice by-products. Through this study, the taste compounds and antioxidant properties of extracts obtained from juice by-products produced after the production of A. keiskei and O. javanica green juice were analyzed, and the availability of high value-added materials was confirmed. Based on these research results, expanding specific R&D for practical use should be explored.

Early IV-injected human dermis-derived mesenchymal stem cells after transient global cerebral ischemia do not pass through damaged blood-brain barrier

Ahn, Ji Hyeon,Chen, Bai Hui,Park, Joon Ha,Shin, Bich Na,Lee, Tae-Kyeong,Cho, Jeong Hwi,Lee, Jae Chul,Park, Jeong-Ran,Yang, Se-Ran,Ryoo, Sungwoo,Shin, Myoung Cheol,Cho, Jun Hwi,Kang, Il Jun,Lee, Choong Wiley (John WileySons) 2018 JOURNAL OF TISSUE ENGINEERING AND REGENERATIVE MED Vol.12 No.7

<P>There is lack of researches on effects of intravenously injected mesenchymal stem cells (MSCs) against transient cerebral ischemia (TCI). We investigated the disruption of the neurovascular unit (NVU), which comprises the blood-brain barrier and examined entry of human dermis-derived MSCs (hDMSCs) into the damaged hippocampal CA1 area in a gerbil model of TCI and their subsequent effects on neuroprotection and cognitive function. Impairments of neurons and blood-brain barrier were examined by immunohistochemistry, electron microscopy, and Evans blue and immunoglobulin G leakage. Neuronal death was observed in pyramidal neurons 5-day postischemia. NVU were structurally damaged; in particular, astrocyte end-feet were severely damaged from 2-day post-TCI and immunoglobulin G leaked out of the CA1 area 2days after 5min of TCI; however, Evans blue extravasation was not observed. On the basis of the results of NVU damages, ischemic gerbils received PKH2-transfected hDMSCs 3 times at early times (3hr, 2, and 5days) after TCI, and fluorescence imaging was used to detect hDMSCs in the tissue. PKH2-transfected hDMSCs were not found in the CA1 from immediate time to 8days after injection, although they were detected in the liver. Furthermore, hDMSCs transplantation did not protect CA1 pyramidal neurons and did not improve cognitive impairment. Intravenously transplanted hDMSCs did not migrate to the damaged CA1 area induced by TCI. These findings suggest no neuroprotection and cognitive improvement by intravenous hDMSCs transplantation after 5min of TCI.</P>
