박상훈(Park, Sang-Hun),안영아(An, Young-A) 한국도시행정학회 2021 도시 행정 학보 Vol.34 No.4

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.

Kim, Sang-Tae,Lee, Seung-Yeon,Kim, Seung-Chul,Byun, Hye-Won,Lee, Sang-Tae,Kim, Mu-Yeal,Hong, Seok-Pyo,Chung, Young-Jae,Park, Ki-Ryong,Lee, Chung-Hee,Lee, Joong-Ku,Heo, Kyeong-In,Lee, Ji-Ye,Lee, Eun-Je National Science Museum of Korea 2011 Journal of Korean nature Vol.4 No.3

We developed the educational purpose mobile application, named "Wild Flowers of Bukhansan National Park (version 1.0)", aiming for easy identification of wild flowers for students and visitors in the park. When visitors find a flower or part of plant in the park, visitors can search for its name utilizing the pictures and characters provided in their own smartphone mobile devices or tablet PCs. The application provides pictures of wild flowers in the park and character-based searching system based on 12 diagnostic features (e.g., growth form, leaf arrangement, flower symmetry, petal color, petal number, sepal number, etc). We adopted the complete floristic survey of Chung and Lee (1962) and added species that we confirmed their distribution in the park during the development of this application. In summary, number of vascular plants in this park was estimated to be 428 taxa including 100 families, 280 genera, 327 species, 1 subspecies, 50 varieties, and 5 formas. We provided a total of 588 pictures representing 358 taxa and each taxon includes multiple pictures in many cases. Included identification quizzes can be an efficient educational tool as well as fun activity for students and visitors who are learning plant species in Korea. Our next step will include GPS function in the application for indicating visitor's location and for providing previously reported sites of the species that we interested in the map of the park. The future application which includes GPS function will be a valuable tool for the monitoring of rare plants, plant researches related to the climate changes, etc. We currently provide Korean iPhone version only, and English version and both of android versions will be serviced soon.

본 원고는 2004년 과학사학자 박성래 교수가 독립 운동가이자 한국 근대 수학교육의 아버지로 부르기 시작한 보재 이상설(李相卨, 1870-1917)이 자연과학에 기여한 내용을 다루고 있다. 한국수학사학회지 2009년 11월 호에 자세히 소개된 〈數理〉를 쓴 시기를 전후하여, 같은 시기에 이상설이 붓으로 쓴 것으로 여겨지는 〈植物學>(이상설, 1899)은 총 4면의 초록 필사본이며, 그 대본(臺本)은 〈植物學啓蒙〉 (Edkins, 1886)으로 영국의 Joseph Edkins(艾約瑟, 1823-1905)가 번역하여 1886년에 간행한 〈西學啓蒙〉 16종 가운데 하나이다. 이상설의 〈植物學>은 이 〈植物學啓蒙〉을 읽으면서 그 책의 내용 중 당시의 조 선 학자가 모르고 있던 새로운 내용을 중심으로 메모를 한 것으로 여겨진다. 본 연구에서는 전통산학과 근대서양수학을 연결하는 〈數理〉를 저술했으며. 우리나라의 정규 교과과정에 수학과 과학을 필수과목으로 지정하고, 첫 번째 수학교과서 〈산術新書〉를 발간함으로 당대 최고의 수학자로 평가된 이상설이 쓴 〈植物學〉을 발굴하여 그 내용과 의미를 최초로 분석한다, 이를 통하여 당시 조선의 서양 과학, 특히 식물학에 대한 이해 수준을 분석하고 〈植物學〉의 원전인 〈植物學啓蒙〉 과 <西學啓蒙〉의 저자에 대하여 알아본다. 이는 당시 수학교육자가 자연과학분야에 행한 교육적 기여를 이해 하는데 필수적인 연구이다. This paper deals with contents that Sang-Seol Lee contributed to the natural science in the 19th century Korea. Prof. Sung-Rae Park, the science historian, called Sang-Seol Lee Father of the Modern Mathematics education of Korea. Sang-Seol Lee wrote a manuscript Botany with a brush in late 19th century. Botany was transcribed from Science Primers: Botany (written by J. D. Hooker), which is translated into Chinese by Joseph Edkins in 1886. The existence of Sang-Seol Lee`s book Botany was not known to Korean scientists before. In this paper, we study the contents of Botany and its original text. Also we analyze people`s level of understanding Western sciences, especially botany at that time. In addition, we study authors of 16 Primers for Western Knowledge. We study the contribution of mathematician Sang-Seol Lee to science education in the 19th century Korea.

The purpose of this study is to evaluate urban parks by location model. For the purpose of doing those, elements of location evaluation - altitude, gradient and accessibility - explored by GIS(Geographical Information System) are selected Evaluation of Location model for urban parks hardly being studied, evaluation of new model by spatial data for analysis shows possibilities in location policies of urban parks, especially, using physical and objective factors. Accessibility is examined by ratio of developed area to total area in Pusan. Altitude and gradient also are explored by each ratio of park areas. The results of evaluation of location model for urban parks in Pusan are summarized as follows; 1) A small scale park is more effective than large scale one in usability on present conditions in Pusan. 2) Most parks are located in areas which are in high altitude and severe slope ratio. Hierarchy of parks as the number of these based on parks' size is improper. Each commune called 'Gu' is very diverse and irrational in numbers and area of urban parks. Therefore, adjustment of irrational parks location is needed 3) Evaluation of this model may be different to facual evaluation because Pusan has many unmade parks. But, unmade parks must continue being constructed. Considering new location model, the problems of that are summarized as follows; 1) The method of analysis using GIS is very objective and effective in abtaining the spatial data. The following study on location and space may be very essential. 2) The problems of weight vague in relations among location elements is very important. Therefore, the more detail works should be required. 3) The model of this study is simple. For more close works, many factors - for example, park form, park management, linkage to other facilitis, etc. - must be considerated

In this paper, we propose a program to identify 14 parking status in a parking lot using a high resolution 360° camera of 12M. The proposed program consists of three steps: Match with plane image, parking area detection algorithm, and discrimination of parking using learning method. Tests on a model car to evaluate the program to identify 14 parking status in a parking lot using a high-resolution 360° camera of 12M showed 100% accuracy for both parking and double parking. Therefore, the effectiveness of a program to identify 14 parking status in a parking lot using a high-resolution 360° camera of 12M proposed in this paper has been proved.

Yan, Bing Chun,Park, Joon Ha,Kim, Sung Koo,Choi, Jung Hoon,Lee, Choong Hyun,Yoo, Ki-Yeon,Kwon, Young-Geun,Kim, Young-Myeong,Kim, Jong-Dai,Won, Moo-Ho Kluwer Academic/Plenum Publishers 2012 Cellular and molecular neurobiology Vol.32 No.8

<P>In the present study, we investigated neuronal death/damage in the gerbil hippocampal CA1 region (CA1) and compared changes in some trophic factors, such as brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF) and vascular endothelial growth factor (VEGF), in the CA1 between the adult and young gerbils after 5 min of transient cerebral ischemia. Most of pyramidal neurons (89%) were damaged 4 days after ischemia-reperfusion (I-R) in the adult; however, in the young, about 59% of pyramidal neurons were damaged 7 days after I-R. The immunoreactivity and levels of BDNF and VEGF, not GDNF, in the CA1 of the normal young were lower than those in the normal adult. Four days after I-R in the adult group, the immunoreactivity and levels of BDNF and VEGF were distinctively decreased, and the immunoreactivity and level of GDNF were increased. However, in the young group, all of their immunoreactivities and levels were much higher than those in the normal young group. From 7 days after I-R, all the immunoreactivities and levels were apparently decreased compared to those of the normal adult and young. In brief, we confirmed our recent finding: more delayed and less neuronal death occurred in the young following I-R, and we newly found that the immunoreactivities of trophic factors, such as BDNF, GDNF, and VEGF, in the stratum pyramidale of the CA1 in the young gerbil were much higher than those in the adult gerbil 4 days after transient cerebral ischemia.</P>

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.

거주지 주변 환경에 대한 인식이 건강증진 목적의 공원이용에 미치는 영향 - 대구광역시 수성구를 대상으로 -

이우성,정성관,박영은,Lee, Woo-Sung,Jung, Sung-Gwan,Park, Young-Eun 한국조경학회 2015 韓國造景學會誌 Vol.43 No.6

본 연구는 건강증진 목적의 공원이용 유무에 따른 거주지 주변 환경 인식의 차이를 살펴보고 거주지 환경인식특성이 공원이용에 미치는 영향을 분석하였다. 연구대상지는 대구광역시 수성구의 근린공원 및 유원지로 설정하였으며, 총 303명의 설문응답 분석을 통해 결과를 도출하였다. 연구결과를 요약하면, 총 16개의 물리적 환경인식 지표들 중 시장 및 상가시설의 접근성, 대중교통의 이용성, 공원 등 녹지공간의 접근성, 충분한 보도, 횡단해야 하는 도로의 수, 운동인구를 포함한 6개의 지표가 유의한 영향을 미치는 것으로 나타났다. 공원을 이용할 확률은 공원 등 녹지공간의 접근성에 대한 만족도가 증가할수록 2.326배, 주변에 운동하는 인구가 많을수록 1.701배, 횡단해야 하는 도로의 수가 적을수록 1.617배, 충분한 보도가 설치되어 있다고 인식할수록 1.642배 증가하는 것으로 분석되었다. 따라서 건강증진 목적의 공원이용을 활성화하기 위해서는 거주지 주변에 이용 가능한 공원녹지를 확대하고 주민들이 지속적으로 이용할 수 있는 운동 프로그램을 개발하는 것이 중요할 것이다. 또한 주거지와 공원을 연결하는 보행자 전용도로를 계획하는 등 보행의 편의성을 높이기 위한 노력이 필요할 것으로 판단된다. The purpose of this study is to analyze the effect of neighborhood environmental perception on park use for health. The study area is focused on neighborhood parks in Suseong-gu, Daegu city. The analysis results are based on questionnaires of 303 respondents. According to the results, park use for health improvement was significantly associated with the perceptions of accessibility to a marketplace, availability of public transit, accessibility to the park, enough sidewalks, number of crosswalks, and athletic population. The probability of park use increased by 2.326 times as the satisfaction of accessibility to the park increased. Also, greater athletic population, fewer crosswalks, and more sidewalks lead to increase of park use by 1.701, 1.617, and 1.642 times, respectively. Therefore, it is important to increase the available neighborhood parks around residences and to develop exercise programs that people can use continuously in order to vitalize park use for health improvement. Also, it is necessary to improve the convenience of walking such as development of pedestrian streets or malls between residences and parks.

This study aims at revealing the physiological responses of dehydration (DH) and rehydration (RH) in intermittent exercises at the work intensity of 70% HR max. First, with general student public, three times of exercise (each for 20 minutes) at the given work intensity were taken, with a break for 25 minutes respectively. Their heart rate, rectal temperature and plasma electrolyte concentration both DH and RH were measured. Second, in two groups of athletes and non-athletes, 9 rounds of exercise (for 100 minutes) and 8 breaks (for 60 minutes) were taken, with RH forced 10 times to compensate for the subjects' water loss. Their change in sweat loss and plasma electrolyte concentration as well as the IVDP(Intensive Voluntary dehydration Phenomenon) were experimented. The summary of this research follows. 1) Mean heart rate and rectal temperature in intermittent exercises were higher at DH than at RH, growing up at the increasing level of DH. 2) RH saw no change in the plasma concentration of Na+, K+ and Cl-, while DH observed a significant increase. 3) HCO₃made a significant decrease at DH before growing up. 4) Mg++ had no change, while Ca++ increased significantly at RH and DH. 5) Lactate showed an increase with significance at RH and DH, especially greater at DH. 6) Osmotic pressure increased meaningfully at DH. 7) Anion gap increased significantly at DH and RH. 8) On the other hand, when the forced RH was held, the group of athletes had greater sweat loss per body surface area than that of non-athletes. 9) The athletes' plasma concentration of Na+ and Cl- revealed a clear decrease. 10) There was seen no significant change in the plasma concentration of K+, Mg++ and Ca++ in both groups. 11) The IVDP occurred at the RH of 2.3ℓfor athletes and more than 2.5ℓfor no-athletes.
