이 연구는 온라인에서 발생하는 소셜 빅데이터 분석을 위해 유사한 주거지역에 위치한 두 개의 공원을 사례 대상으로 선정하여 비교분석 하였다. 이를 위해 도시공원에 대한 인식을 분석하고 개별공원의 특성과 이용상의 차이를 확인하는 방법으로써 소셜 네트워크 분석의 적용 가능성을 확인하고자 한다. 분석은 빅데이터를 근거로 하며, 연구의 핵심이 키워드 분석임에 따라 저자가 특허 등록한 ‘감성정보 분석 방법’의 일부를 활용하였다. 분석결과, 양재시민의 숲과 서서울호수공원은 계절을 체험하고, 느낄 수 있는 산책 공간으로 이용하고 있는 것으로 판단된다. 서서울호수공원은 주로 가족 단위로 공원의 시설과 공원 콘텐츠를 이용하는 반면에 양재시민의 숲은 가족 뿐만 아니라 친구 등 이용대상이 상대적으로 폭넓고 공원 시설 외에 양재천, 둘레길, 맛집 등 주변 환경과 연계된 이용 양상을 보이는 것으로 해석된다. 이러한 연구 결과는 도시공원 운영 및 관리에 있어 공원 이용객의 특성, 이용시간 등을 고려하여 프로그램을 개발하고 운영할 필요가 있음을 시사한다. In this study, two parks located in similar residential areas were selected as case subjects for the analysis of social big data analysis occurring online. For this purpose, the applicability of social network analysis is to be checked as a method of analyzing the perception of urban parks and identifying differences in characteristics and use of individual parks. The analysis is based on big data, and as the core of the study is keyword analysis, a part of the ‘emotional information analysis method’ registered by the author in the patent was used. As a result of the analysis, it is judged that Yangjae Citizen"s Forest and West Seoul Lake Park are being used as walking spaces where you can experience and feel the seasons. West Seoul Lake Park mainly uses the park"s facilities and park contents on a family basis. On the other hand, Yangjae Citizen"s Forest is interpreted as showing a relatively wide range of use for not only family but also friends, and it is used in connection with the surrounding environment such as Yangjaecheon Stream, Dullegil, and restaurants in addition to park facilities. These research results suggest that it is necessary to develop and operate programs in consideration of the characteristics and hours of use of park users in the operation and management of urban parks.

본 연구는 근린공원에 대한 이용자의 공원지각환경이 건강증진인식에 미치는 영향을 분석하기 위해 경상남도 창원시의 8개 근린공원을 대상으로 공원별 현장조사 및 설문조사를 실시하였다. 연구결과에 따르면, 먼저 공원별 공원지각환경에서는 대부분의 공원이 집에서 공원까지의 거리와 집에서 공원까지의 길 환경이 높게 평가된 반면, 수공간과 공원 내 다양한 볼거리는 충분하지 못한 것으로 분석되었다. 다음으로 23개의 지각환경 변수들을 요인분석한 결과, 경관성, 안락성, 접근성, 활동성, 편의성, 쾌적성의 6개 요인으로 분류되었다. 이를 토대로 건강증진인식과 지각환경요인과의 관련성을 분석한 결과, 8개 공원 중 4개 공원에서 지각환경요인이 신체적 건강증진인식에 유의한 영향을 주는 것으로 나타났다. 특히, 접근성과 활동성이 3개의 공원에서 영향력이 있는 변수로 분석되었다. 또한, 심리적 건강증진인식의 경우, 8개 공원 중 5개 공원에서 유의한 영향을 주는 것으로 나타났으며, 접근성이 4개의 공원에서 영향력이 있는 변수로 평가되었다. 이상과 같은 결과들은 기존의 공원 환경을 개선하고, 새로운 공원을 조성하고자 할 때 효율적인 기초자료로 활용될 수 있을 것으로 판단된다. The purpose of this study was to analyze the effect of environmental perception in neighborhood parks on user's recognition of health improvement. This study used objective field survey data and subjective user survey data at 8 neighborhood parks in Changwon City. According to the results, the perceptions of distance and street environment from home to park were evaluated highly but the perception of water spaces and various attractions within the parks were rated lowly in most of parks. As a result of factor analysis, 23 environmental perception variables were classified into 6 factors such as scenery, comfort, accessibility, activity, convenience and amenity. For the result of regression analysis between environmental perceptions and user's recognition of health improvement based on 6 factors, the recognition of physical health improvement was significantly influenced from environmental perception factors in 4 parks among 8 parks. 'Accessibility' and 'activity' were analyzed as the meaningful factors in 3 parks. Also, recognition of mental health improvement was significantly influenced from environmental perception factors in 5 parks among 8 parks and especially 'accessibility' was showed as the significant factor in 4 parks. The findings from this study can contribute to improve the physical environments of the present parks and can be a basic data for new park development.

본 연구의 목적은 경상남도 창원시를 대상으로 근린공원 환경에 대한 만족도가 신체활동과 건강증진 목적의 공원이용횟수와 체질량지수(BMI)에 의한 건강수준에 미치는 영향을 분석하는 것이다. 설문조사는 창원시 성산구와 의창구 도심지역에 분포하는 8개 근린공원의 이용자와 그 주변에 거주하는 429명의 주민들을 대상으로 실시하였고, 설문분석은 근린공원 환경에 대한 만족도가 신체활동과 건강에 미치는 영향을 분석하기 위해 일대일대응 선형회귀분석을 활용하였다. 연구결과를 요약하면, 공원을 이용하지 않는 주된 이유는 시간적 여유의 부족, 공원까지의 이동거리와 소요시간, 공원 내 이용시설의 부족 등이고, 공원을 이용하는 주된 이유는 공원까지의 접근성, 걷기 또는 산책, 휴식시설, 수목이나 그늘, 운동공간의 다양성 등으로 나타났다. 공원 이용자의 경우, 공원에서 걷기나 산책을 가장 많이 하고, 주 2회 이상 평균 10분 정도 걸어가서 1시간 정도 운동을 하는 것으로 나타났다. 공원과 그 주변의 물리적 환경 중에서 집에서 공원까지의 거리와 이동하는 가로 환경에 대한 만족도가 높았고, 공원 내 수공간이나 볼거리 등에 대한 만족도가 낮게 나타났다. 다음으로, 운동목적의 공원이용 여부, 공원이용시간, 공원이용의 만족도와 건강증진 효과, 공원까지의 거리, 따른 건강증진 효과만이 유의수준 10% 이내에서 상호관련성이 있는 것으로 나타났다. 향후에도 공원의 신체활동과 건강 증진 효과에 대한 실증적 사례노약자들의 공원이용 편이성 등이 유의수준 5% 이내에서 신체활동과 건강증진 목적의 공원이용횟수에 긍정적인 영향을 보였고, 체질량지수와는 공원이용에 를 지속적으로 축적해 나갈 필요가 있으며, 이를 통해서 각종 개발용도로 전환되거나 그 면적이 축소되고 있는 도시지역의 공원 및 녹지공간을 보전 확대시켜 나가고, 신체활동 및 건강증진 장소로서의 기능을 제고하기 위한 공원계획 설계 요소를 도출하는데 근거 자료를 제공하는 것이 가능할 것으로 판단된다. The purpose of this study is to analyze the effects of satisfaction in neighborhood park environments located in the Changwon-si of Gyeongsangnam-do, South Korea, on physical activity, the number of parks used for health improvement, and health levels based on Body Mass Index(BMI). Accordingly, a survey was conducted of 429 nearby residents and users of eight neighborhood parks located in urban areas of Seongsan-gu and Uichang-gu in the Changwon-si. The correlation between the environmental perception of neighborhood parks and physical activity and health, which was observed in the survey results, was analyzed using one-by-one linear regression analysis. By summarizing the study results, it was found that the primary reasons for avoiding park use were lack of time, time and effort required to reach the park(i.e., distance from the park), and lack of facilities within the park. Conversely, the primary reasons for using the park included accessibility, walking or strolling, leisure facilities, trees or shade, and diversity in exercise areas. In the case of park users, walking or strolling was the most common activity in the park. On average, park users walked to the parks for 10 minutes and exercised for an hour at least twice per week. With respect to the physical environment of the parks and surrounding areas, park users showed a high level of satisfaction with the distance between their houses and parks and the street environment. On the contrary, they exhibited low levels of satisfaction with water spaces and sightseeing within the parks. Subsequently, it was shown that the number of people using the parks for physical activities and health improvement was positively influenced(within a 5% significance level) by the intent to use the park for exercise, time spent in the park, satisfaction with park use and health improvement, distance to the park, and the convenience of using the park for the elderly. However, only the health improvement gained from park use was found to exhibit a correlation with BMI at the 10% significance level. Continuous accumulation of practical case studies on physical activities in parks and their health improvement effects is required. Through this, park spaces that are under the threat of reduction or elimination owing to various development plans can be conserved and expanded. Furthermore, such case studies can be used to provide data as the basis for deriving park plans and designs that improve parks' functions as sites of physical activity and health improvement.

Lee, Sunghun,Lee, Dong Hun,Park, Bong-Woo,Kim, Riyoun,Hoang, Anh Duc,Woo, Sang-Keun,Xiong, Wenjun,Lee, Yong Jin,Ban, Kiwon,Park, Hun-Jun Nature Publishing Group UK 2019 Experimental and molecular medicine Vol.51 No.2

<▼1><P>Vascular regeneration in ischemic hearts has been considered a target for new therapeutic strategies. It has been reported that ETV2 is essential for vascular development, injury-induced neovascularization and direct cell reprogramming of non-endothelial cells into endothelial cells. Thus, the objective of this study was to explore the therapeutic potential of ETV2 in murine models of myocardial infarction in vivo. Direct myocardial delivery of lentiviral ETV2 into rodents undergoing myocardial infarction dramatically upregulated the expression of markers for angiogenesis as well as anti-fibrosis and anti-inflammatory factors in vivo. Consistent with these findings, echocardiography showed significantly improved cardiac function in hearts with induced myocardial infarction upon ETV2 injection compared to that in the control virus-injected group as determined by enhanced ejection fraction and fractional shortening. In addition, ETV2-injected hearts were protected against massive fibrosis with a remarkable increase in capillary density. Interestingly, major fractions of capillaries were stained positive for ETV2. In addition, ECs infected with ETV2 showed enhanced proliferation, suggesting a direct role of ETV2 in vascular regeneration in diseased hearts. Furthermore, culture media from ETV2-overexpressing cardiac fibroblasts promoted endothelial cell migration based on scratch assay. Importantly, intramyocardial injection of the adeno-associated virus form of ETV2 into rat hearts with induced myocardial infarction designed for clinical applicability consistently resulted in significant augmentation of cardiac function. We provide compelling evidence that ETV2 has a robust effect on vascular regeneration and enhanced cardiac repair after myocardial infarction, highlighting a potential therapeutic function of ETV2 as an efficient means to treat failing hearts.</P></▼1><▼2><P><B>Cardiovascular disease: New hope for healing the heart</B></P><P>A gene therapy strategy that stimulates cardiovascular repair could improve recovery for heart attack patients. Heart attacks inflict severe damage on the heart and blood vessels, tissues with limited capacity for self-repair. Researchers led by Kiwon Ban of the City University of Hong Kong and Hun-Jun Park of the Catholic University of Korea, Seoul, have now demonstrated that a gene responsible for cardiovascular development can also efficiently stimulate heart repair. They used viruses to deliver the gene into a mouse model of heart attack, and showed that treated heart tissues exhibited strong recovery relative to untreated controls. The treatment reduced scar tissue formation and promoted proliferation of the cells lining blood vessels and blood vessel formation, measurably improving heart function. This approach could lay the groundwork for treating a common potentially fatal event.</P></▼2>

김영훈(Kim, Young-hun),장성호(Jang, Sung-Ho),박윤기(Park, Yun-Ki) 용인대학교 무도연구소 2012 武道硏究所誌 Vol.23 No.1

이 연구는 역대 YMCA 체육을 토대로 하여 구체적으로 살펴보고자 한다. 이에관해 생활체육 활성화 방안 모색을 제시하는데 논의 및 결론을 도출하였다. 이는 다음과 같이 확인할 수 있다. 첫째, 한국에서의 YMCA운동은 1899년 경성에서 선교활동을 시작되었다. 둘째, YMCA의 전인교육정신인 지(智)·덕(德)·체(體)의 정신과 통하는 정신으로서 비폭력, 민주주의의 실천교육과 상통하는 정신이었다. 셋째, 이상재의 교육사상은 인간의 본질적인 면에 치중하여 올바른 인격체로 양성하는 것으로 지·덕·체의 전인적 교육이었음 알 수 있었다. 넷째, 서울 YMCA의 창립과 역사적 배경을 보면 서울YMCA는 1903년 10월 28일 창립하였다. 다섯째, 서울YMCA를 도입, 회원들에게 지도한 스포츠로는 야구, 농구, 배구, 축구, 유도, 검도, 체조 등이 있었다. 이상과 같이 종합해 볼 때, 역대 YMCA 체육의 역사에서 보이듯이 그 정책을 통해 한국생활체육의 활성화를 위한 방안 모색에 따른 정체성을 제시할 수 있는 것이다. This research is looked at concretely is based on the generation of YMCA physical training. It derive a discussion and conclusion to grope a plan to activate living physical training. This can be confirmed by the following essay. First, the YMCA exercise in Korea started in Gyeong-sun, 1899 as a missionary activity. Second, the mind of former education of YMCA’s just·morality·formality was a mind connected to the communicating with anti-violence, democratic practice education. Third, Lee Sang-Jea’s educational method is to bring up the personality to the right side valued on true nature of a human being, which indicates that his educational method is for the whole man. Fourth, looking at the foundation and historical backround, Seoul YMCA was established on 28th October 1903. Fifth, sports that Seoul YMCA guided to members were baseball, basketball, volleyball, football, judo, kendo, gymnastics etc. To round up all the above statements, the identity following a plan to activate Korea living P.T can be derived through the policy as seen in YMCA physical training’s history in generations.
