12주 복합운동프로그램이 전ㆍ후기노인의 체구성과 SFT 요인에 미치는 영향
임남훈,김예성 한국체육대학교 체육과학연구소 2019 스포츠사이언스 Vol.37 No.1
The purpose of this study is to examine the effectiveness of the combined exercise program for elderly people conducted by the department of sport and healthy aging in Korea National Sport University. To do this, we compared and analyzed data on body composition factors and SFT factors. The subjects of this study were 85 elderly people who understand the purpose of this study and participate voluntarily in this program among members of elderly welfare centers in Seoul. For the implication of appropriate exercise method according to age group, 37 elderly people under the age of 75(YOA) and 48 elderly people over 75 years old(OOA) were separately analyzed. The combined exercise program consisted of healthy gymnastics and new sport exercise and was conducted for 12 weeks for 60 minutes once a week. Data were analyzed using SPSS ver.23.0. The mean and standard deviation of the variables were calculated and corresponding sample t-test was conducted to analyze the difference between pre- and post- test. The results of the study are as follows. First, among the constituent factors of YOA group, only the weight items decreased significantly. In the OOA group, skeletal muscle mass was significantly increased, and the body fat percentage decreased significantly. Second, YOA group showed significant increase in lower body strength, lower body flexibility, agility, and total endurance, and OOA group showed significant increase only in flexibility item of lower body. The results of this study showed that the combined exercise program had a positive effect on the change of the body composition partly, and the change of the SFT factor was more effective for the YOA group than the OOA group. Based on the results of this study, we discussed how to develop a more effective elderly exercise program. 본 연구의 목적은 65세 이상 노인을 대상으로 한국체육대학교 노인체육복지학과에서 실시한 복합운동프로그램의 효과성을검증하는 것이다. 이를 위해 체구성 요인과 노인체력검사(SFT) 요인에 관한 사전ㆍ사후 데이터를 비교분석하였다. 연구대상은서울특별시에 소재한 노인복지기관을 이용하는 노인 가운데 본 연구의 취지를 이해하고 자발적 참여의사를 밝힌 85명의노인이다. 연령대에 따른 적합한 운동방식에 대한 함의를 도출하고자 75세 미만의 전기노인(YOA) 37명, 75세 이상의 후기노인(OOA)은 48명으로 분류하여 분석을 실시하였다. 복합운동프로그램은 건강체조와 뉴스포츠 운동으로 구성되며 주 1회 60분씩12주간 실시되었다. 뉴스포츠 운동으로는 스포츠스태킹, 셔플보드, 시나볼로 총 3종목을 활용하였다. 자료처리는 통계프로그램 SPSS Ver.23.0을 이용하여 변인의 평균 및 표준편차를 산출하였고 사전ㆍ사후 검사의 차이를 분석하기 위해 대응표본t-test를 실시하였다. 연구결과는 다음과 같다. 첫째, 체구성 요인 중 YOA 집단은 체중 항목만 유의하게 감소하였으며 OOA 집단의 경우 골격근량 항목은 유의하게 증가하였고 체지방률 항목은 유의하게 감소하였다. 둘째, 노인체력검사(SFT) 요인중 YOA 집단은 하체의 근력, 하체의 유연성, 민첩성, 전신지구력 항목이 유의하게 증가하였으며 OOA 집단은 하체의 유연성항목만 유의하게 증가하였다. 이러한 결과를 볼 때 복합운동프로그램은 체구성의 변화에 부분적으로 긍정적 영향을 미쳤으며노인체력검사(SFT) 요인의 변화에 있어 후기노인(OOA) 집단보다 전기노인(YOA) 집단에 큰 효과성을 지니고 있음을 알 수있다. 이러한 연구결과에 기반하여 보다 효과적인 노인운동프로그램으로 발전시키는 방안에 대해 논하였다.

미백 기능성 성분의 혼합물에 대한 미백 활성 및 안정성에 관한 연구
이윤희 ( Youn Hee Lee ),임남훈 ( Nam Hoon Lim ),정민석 ( Min Seok Joung ),김중회 ( Joong Hoi Kim ),심상수 ( Sang Soo Sim ) 대한화장품학회 2005 대한화장품학회지 Vol.31 No.4
알부틴, 유용성감초추출물(GLY), 아스코빌글루코사이드(AA2G), 에칠아스코빌에텔(EAE)은 현재 미백 기능성성분으로 가장 많이 사용되어지는 성분들이다. 위의 미백 성분 중 어느 성분을 같이 혼합하여 사용하였을 때 미백효과가 더 효과적인가를 알아보기 위하여 tyrosinase 활성 억제와 B-16 melanoma cells에서 MSH에 의한 멜라닌 생성 억제 정도를 측정하였다. 알부틴과 유용성감초추출물은 농도 의존적으로 정제된 tyrosinase 활성을 저해하였다. 유용성감초추출물(GLY)과 아스코빌글루코사이드(AA2G)를 같이 사용하였을 때나 유용성감초추출물(GLY)과 에칠아스코빌에텔(EAE)을 같이 사용하였을 때는 유용성감초추출물(GLY)을 단독으로 사용하였을 때보다 tyrosinase 활성 저해효과가 상승하였으나 알부틴과 다른 성분들을 같이 사용하였을 때는 그러한 현상을 보여주지 못했다. B-16 melanoma cell을 이용한 MSH로 유도된 melanin 생성실험에서는 유용성감초추출물 (GLY)과 에칠아스코빌에텔(EAE)을 같이 사용하였을 때 멜라닌 생성 억제 효과가 유용성감초추출물(GLY)을 단독으로 사용하였을 때보다 현저히 증가하였다. 유용성감초추출물(GLY), 알부틴, 아스코빌글루코사이드(AA2G), 에칠아스코빌에텔(EAE)의 복합물을 일반적인 크림제형에 혼합하여 25℃, 45℃에서 30일간 안정성(stability)을 관찰하였으며 특이한 함량변화는 관찰되지 않았다. 이상의 결과로 미루어 볼 때 유용성감초추출물(GLY)과 아스코빌글루코사이드(AA2G), 에칠아스코빌에텔(EAE)은 같이 사용함으로서 미백효과를 더 상승시킬 수 있다고 사료된다. Recently, arbutin, oil soluble licorice extact (GLY), ascorbyl glucoside (AA2G), and ethyl ascorbyl ether (EAE) have been widely used as functional whitening ingredients. To Investigate which combination between the above agents could be more effective for whitening effect, tyrosinase activity and MSH-induced melanin production in B-16 melanoma cells were investigated. Both GLY and arbutin dose-dependently inhibited purified tyrosinase activity. The inhibitory effects of GLY with AA2A or EAE on Drosinase activity were more potent than those of GLY alone, whereas that of arbutin with other ingreadients did not show those effects. In MSH-induced melanin production in B-16 melanoma cells, the mixture of Gly and EAE more significantly reduced melanin formation than Gly alone. Stability of mixture of GLY, arbutin, AA2A and EAE exposed at the temperature of 25℃, 45℃ for 30 days were also investigated. All of the combinations of whitening agents did not show any critical changes in their composition stability. These data suggest that the combination of GLY and vitamin C derivatives such as AA2G and EAE may be useful for the promotion of whitening effect.

To qualitatively understand the deformation processes and damages in the human body caused by high-speed impact, we conductedexperimental and computational investigations for bullet penetration into viscoelastic ballistic gelatin blocks. Because it is difficult tomeasure the strain rate-dependent material properties of viscoelastic gelatin blocks during high-speed impact, the material properties thatare indirectly defined by the stress relaxation test were used for the computational simulation. We also conducted some firing experimentsand analyzed the deformation processes of the structures. In particular, the passing through times and the shapes of the temporaryand permanent cavities inside the ballistic gelatin blocks were analyzed and compared. This data reveals that the employed material models,with some modifications for the FE simulation, are sufficient for predicting the high-speed impact behaviors. To investigate theshapes of the permanent cavities and fragments made by bullets inside the gelatin blocks, two-dimensional sectional images were takenby an industrial CT scanner and a three-dimensional CAD model was constructed based on these images.

The purpose of this study was to provide basic data which is based on physical activity constraints factors for elderly with disabilities. To achieve the goal, paper research was conducted at National Center for biotechnology Information pubmed. This research engine enables to access US National Library of Medicine. Total 82 papers were selected which was related to both Physical Activity for Elderly with disabilities and ICF factors. Sub factors which related with Body functions and structures are Mental Function, Neuromusculoskeletal and movement-related function, Functions of the digestive, metabolic and endocrine systems, Structure related to the genitourinary and reproduce systems, Functions of cardiovascular, haematological, Immunological and respiratory systems and Structure related digestive. Sub factors which related with Activity and participation are Self-care, Mobility, Learning and applying knowledge and Domestic life. Sub factor which related with Environmental factors are Support and relationships and Natural environment and human made changes to environment. In conclusion, regularly physical activity has positive effect on ICF classification system, so there is need to develop and provide physical activity program which considered the types of disabilities.
