        한강시민공원의 이용자 활동 특성 분석 및 개선방안 연구

        송지연(Song, Ji-Yeon),박진아(Park, Jin-A) 한국도시설계학회 2013 도시설계 : 한국도시설계학회지 Vol.14 No.4

        본 연구는 한강시민공원을 이용하는 시민들의 특성 및 이용행태를 분석하고 초기 조성방향과 실질적인 이용행태 간의 차이를 확인하여 향후 공원계획과 관리에 대한 시사점을 제시하는 것을 목적으로 둔다. 대상지별 분석 결과를 정리하면 첫째, 여의도한강공원은 주변 지역에 업무, 상업지구가 분포하고 문화 및 축제 프로그램이 많다는 특성을 가지고 있다. 그러나 이와 상관없이 인근 주민이나 업무, 상업 지구에 종사하는 사람들이 휴식이나 산책, 가벼운 운동 등을 위해 한강시민공원을 일상적으로 이용하는 것으로 분석되었다. 둘째, 반포한강공원은 주변이 주거지역이라는 특성을 가지고 있으며 한강르네상스 사업으로 시설이 조성되어있다. 그러나 시설 이용을 목적으로 하기보다 자전거 이용 중에 휴식을 취하기 위해 공원을 찾거나 휴식 및 산책 또는 가벼운 운동을 하는 행태가 나타났다. 본 연구는 이러한 결과를 바탕으로 한강시민공원의 실질적인 이용행태를 알 수 있으며 생활권 공원으로서의 한강공원의 활용도가 높았음을 확인하였다는 측면에서 의의를 가질 수 있다. Han-Gang Park, Seoul?s representative and iconic public places is dedicated to the role of the theme park. The purpose of this study is to compared the current user behavior and purpose of the composition in past, and derived the implications for planning and management for Han-Gang Park. The results of analysis target area shows that, firstly, Yeoido Han-Gang Park is surrounded by commercial and business district. That area has the many cultural, festival programs. But, without specific purpose, Yeoido Han-Gang Park has been used for resting or walking, and light exercise. And vicinity residents, office worker, or commercial area worker were using regularly. In case of Banpo, environs have a property of residential area and Banpos ? facilities were made by Han-Gang Renaissance Project. But most people use the park to take a rest in the way riding a bicycle rather than use facilities. On these results, we can recognize the practical usage behavior. And this study has significance that Han-Gang Park appeared to show higher utilization level of the citizens as a neighborhood space.

      • Development of a Mobile Application, "Wild Flowers of Bukhansan National Park (version 1.0)", for Identification of Plants in Bukhansan National Park

        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.

        The influence of obesity on pediatric conscious sedation

        Park, Ki-Tae,Kim, Ji-Yeon,Park, Sung-Dong 大韓小兒齒科學會 2006 大韓小兒齒科學會誌 Vol.33 No.1

        Objective: This study was conducted to investigate as to whether obesity have any effects on conscious sedation outcomes. Methods: Forty children (mean age 30.5 months, mean height and weight were 91.3 cm, 14.3 kg respectively) were sedated with chloral hydrate (60 mg/kg) and hydroxyzine (25 mg). The relative obesity rate of the patients was obtained by the proportion of height to weight and the tonsil size of the patients was classified by Brodsky's scale. The overall sedation outcomes were evaluated by Houpt's scale. The pulse and respiratory rates during sedation were also evaluated. Results: The obesity of the patients had no statistically significant effects on movement, crying during sedation. However, an increase in obesity had negative effects on the overall conscious sedation outcomes. Conclusion: This investigation demonstrated that increased obesity may cause detrimental effects on pediatric conscious sedation outcomes. 본 연구의 목적은 소아의 비만도가 진정요법의 효과에 미치는 영향을 알아보는 것이다. 삼성서울병원 소아치과에 내원한 환자 중 ASA Ⅰ또는Ⅱ에 해당하는 40명의 환아 (평균연령 30.5개월, 평균신장 91.3cm, 평균체중 14.3kg)를 대상으로 chloral hydrate(60mg/kg) 및 hydroxyzine(25mg)을 사용하여 진정요법을 시행하였다. 환아의 체중과 신장을 이용하여 환아 각각의 비만도를 계산하였고 Broadsky's scale을 이용하여 편도선의 크기를 측정하였다. 진정요법에 대한 결과는 Houpt's scale(수면, 움직임, 울음, 전반적인 행동지수)을 이용하여 평가하였다. 환아의 비만도는 진정효과중 움직임과 울음에 대하여는 통계학적으로 유의한 차이를 만들지 않았으나 비만도가 증가 할수록 전반적인 행동지수가 유의하게 나빠지는 결과를 보였다.

        Production and Characterization of Enzymes Involved in Chitin Catabolic Cascade from a Bacterial Strain Isolated from Soil

        ( Ji Hyun Lee ),( Jeong In Lee ),( So Yeon Park ),( Yoo Kyeong Jang ),( You Bin Lim ),( Hye Yoon Lee ),( Young Min Jung ),( Hae Chang Lee ),( Jong Hwa Lee ),( Shaheen Amna ),( Jae Kweon Park ) 한국키틴키토산학회 2019 한국키틴키토산학회지 Vol.24 No.1

        The present study was aimed to isolate the bacteria producing chitinolytic enzymes including chitin deacetylase (CDA) from soil origin. About 24 bacteria were screened for their chitinolytic enzymes producing ability on the basis of colloidal chitin. Amongst one of the most potent isolates designated to JI-02 was further selected as the most prominent chitinolytic and CDAlike enzyme (CDA-X) producer based on the ability of deacetylation of an artificial substrate pNP-acetamilide. The maximum production of CDA-X in crude enzyme from JI-02 was observed in the presence of 1% colloidal chitin at 37°C and pH 6.4 after 120 h of incubation. Potent enzyme activity of CDA-X was determined toward pNP-acetamilide, demonstrating that optimal pH, temperature and ionic strength of the CDA-X were assessed to be 7.0, 52°C and 125 mM, respectively. Unexpectedly, Nacetylglucosamine (GlcNAc) was not fully converted by the action of CDA-X to glucosamine (GlcN) under the established conditions. Further study on enzyme activity toward chitin-oligosaccharides consisting of multi-N-acetylglucosamine (GlcNAc)n, n=2-5 may be necessary to elucidate the mode of action which requires the minimum size of (GlcNAc)n. However, our data suggest that CDA-X can convert chitin to chitosan with the maximum yield of approximately 0.08g/L during the fermentation of the strain in the presence of chitin. Furthermore, we found that crude enzyme showed the significant chitosanolytic activity. Taken together, our data suggest that the strain JI-02 may be a potential candidate as a particular strain for better understating of chitin catabolic pathway.

        때까치(Lanius bucephalus)의 비번식기 먹이꽂이 행동에 관한 연구

        박경현(Park, Kyung-hyun),김지연(Kim, Ji-yeon) 한국조류학회II 2020 한국조류학회지 Vol.27 No.1

        2003~2009년 10월부터 다음해 2월까지 길동생태공원에서 때까치의 먹이꽂이 212개를 조사한 결과, 11월 중순부터 먹이꽂이가 급격히 증가하여 추위가 본격화되기 전 먹이를 저장함을 알 수 있었다. 먹이꽂이에 이용된 동물은 메뚜기목과 양서강이 가장 많았고, 그 외 절지, 연체, 환형, 척추동물문의 다양한 먹이를 겨울철 먹이로 이용하였고, 2개월 내에 70%가량이 없어졌다. 먹이꽂이 높이는 평균 131.5cm로, 아까시나무와 버드나무를 주로 이용하였으나, 그 외 다양한 수종도 이용하였다. 수종보다는 먹이를 꽂기 쉬운 높이의 수목 중 DBH 3cm미만인 교목을 선호하였다. 먹이꽂이와 관찰로의 거리를 조사한 결과, 관찰로 주변을 더 선호하였다. 길동생태공원에서 비번식기에 서식하는 때까치의 먹이꽂이 행동에 관한 연구 결과, 도시 비오톱에서 때까치의 비번식기 서식을 위하여 먹이원이 되는 곤충과 양서류 등 종다양성을 높게 유지하는 것이 필요하며, 일정한 거리 내에 습지와 개방된 초지, 산림이 어우러진 수직적 자연경관을 유지해야 함을 알 수 있었다. 2003~2009 from every October to following February(7 years), we have observed 212 impaled preys of Lanius bucephalus in Gildong Ecological Park. As a result, we got to know that the number of impaled preys sharply increased from the middle of November in every year, and the food storage of preys has been completed before severely cold time. The main preys used for its impalement were orthoptera and amphibia. Besides, various preys such as arthropoda, mollusca, annelida and vertebrate were also used as impaled food for winter time. And 70% of its cache of preys disappeared within 2 months. The impalement location on a tree was 131.5cm high of trees on average. And then it mainly used Salix koreensis and Robinia pseudoacacia for impalement but it also used various other trees. It preferred the trees of which DBH(Diameter at Breast Height) is less then 3cm among the trees of easy-to-impale height rather than wood species. According to examining the distance between impalement and observation road, it is recognized that Lanius bucephalus liked the surrounding area of observation road. As a result of this study on impaling behavior of Lanius bucephalus in non-breeding season in Gildong Ecological Park, for the inhabitation of Lanius bucephalus in non-breeding season at the biotop in urban area, we got to know it is required that biodiversity on food source such as insect and amphibian etc. should be kept in a high level, and also within a certain boundary, vertical natural landscape which combines wetlands, open pastures and forest should be maintained.

        태안해안국립공원 학암포 지역의 조류 현황

        강화연(Hwa-Yeon Kang),서슬기(Seul-Gi Seo),박세영(Se-Yeong Park),이지용(Ji-Yong Lee),권영수(Young-Soo Kwon) 국립공원연구원 2015 국립공원연구지 Vol.6 No.4

        서해안 육상지역을 통과하는 조류의 이동생태를 파악하기 위해, 2014년 7월부터 2015년 6월까지 태안해안국립공원 학암포 지역의 조류상을 조사하였다. 조사 결과 관찰된 조류는 총 14목 30과 88종 23,230개체이며, 평균 조사일당 159.7개체가 관찰되었다. 전체 우점종은 괭이갈매기 Larus crassirostris 21.1%, 되새 Fringilla montifringilla 18.5%, 박새 Parus major 12.7%, 붉은머리오목눈이 Paradoxornis webbianus 8.2%, 노랑턱멧새 Emberiza elegans 5.8% 순이었다. 이동시기인 5월과 10월에는 각각 56종, 조사일당 평균 310.5개체로 가장 많은 종과 개체수가 기록되었다. 종과 개체수가 가장 적은 시기는 여름철인 8월로, 기록된 종 수는 24종이며 조사일당 평균 95개체가 관찰되었다. 종풍부도(R ) 지수는 가장 많은 종이 관찰된 5월에 가장 높았으나, 종다양도(H )와 종균등도(E )는 오히려 이동시기에 낮은 편으로 나타났으며, 이는 일부 상위 우점종의 개체수가 월등히 증가했기 때문인 것으로 판단된다. 환경부, 문화재청, IUCN 등이 지정한 멸종위기 및 법정보호종은 총 9종이 관찰되었다. From July 2014 to Jun 2015, bird survey was conducted in Hakampo, Taeanhaean National Park. A total of 23,230 and 159.7 per day of birds representing 14 orders, 30 families, 88 species were observed. The most abundant species were the Black-tailed Gull Larus crassirostris (21.1%), the Brambling Fringilla montifringilla (18.5%), the Great Tit Parus major (12.7%), the Vinous-throated Parrotbill Paradoxornis webbianus (8.2%), Yellow-throated Bunting Emberiza elegans (5.8%). The number of species and individual was the highest in May and October, respectively, as 56 species and 310.5 individual per day were recorded. According to Korean Ministry of Environment, Cultural Herigage Adinistration of Korea and IUCN Red List, a total of 9 protected species were recorded during the survey.

      • 골격근 근형질세망의 ATPase활성도에 대한 Vanillylnonanamide의 영향

        박경섭,홍장희,류영수,성지연,허강민,임종호,이재흔,석정호 충남대학교 의과대학 지역사회의학연구소 1999 충남의대잡지 Vol.26 No.2

        To investigate the effect of vanillylnonanamide(VN) on the ATPase activity of the sarcoplasmic reticulum(SR) of the skeletal muscle, we prepared the SR vesicles from the back muscle of the rabbit, and measured ATPase activity. The results as follows: Ca-ATPase activity was about 50% in the total ATPase activity of skeletal muscular SR. In the reaction mixture with calcium, 100μM VN increased ATPase activity to 20%, and 100 nM and 10 μM thapsigargin(THP) inhibited the ATPase activity to 50% and 60%, respectively. And 100 μM VN plus 100 nM or 10 μM THP more inhibited ATPase activity than THP alone did it. However, without calcium, 100μM VN did not affect ATPase activity, and 10 μM THP inhibited it to 41%, but VN plus THP inhibited it to 31%. The above results show that VN in the reaction mixture with or without calcium has the different action to ATPase activity when it is used alone or together with Ca-ATPase inhibitor THP. This suggests that VN might increase or decrease the skeletal SR Ca-ATPase activity through affecting the lipid membrane around the Ca-ATPase.

        활동이론의 관점에서 바라본 박물관, 커뮤니케이션, 그리고 학습

        박지연,이수민,이병준 한국문화교육학회 2011 문화예술교육연구 Vol.6 No.4

        Museum is a medium which communicates with previous generation's experiential memories and present generation's cultural memories. Therefore, the communication is a core task in museum. Museum needs mediums like exhibition and education and we have to discuss how to structuralize these things. The museum communication could be explained through the Cultural-Historical Activity Theory(CHAT). The CHAT has been developed by several theorists like Vygotsky. Especially, the third generation's CHAT has been developing by Engeström. It is a worthy theoretical structure that can show museum as a messenger of communication in society and its communication problems. This study is based on the CHAT and analyzes museum in a social activity system and activity system in a museum from micro/macro-scopic view. Also, it produces practical models that connect museum with community art field and museum with schools. 박물관은 앞선 세대의 체험적 기억을 현 세대에게 문화적 기억의 형태로 커뮤니케이션하는 매개체이다. 따라서 박물관에서 소통(communication)이라는 개념은 핵심적인 과제일수 밖에 없다. 박물관은 그 자체로 전시와 교육과 같은 매체(medium)를 필요로 하며 이를 어떻게 구조화할 것인가의 문제가 박물관커뮤니케이션의 측면에서 논의될 필요가 있다. 이러한 거시적, 미시적 차원의 박물관커뮤니케이션의 과제는 비고츠키와 여러 이론가들의 연구성과를 정리하고 발전시킨 활동이론에 의해 잘 설명될 수 있을 것으로 보인다. 특히 Y. Engeström에 의해 발전된 제3세대 활동이론은 사회속에서의 커뮤니케이션의 전달자로서의 박물관과 박물관내에서의 커뮤니케이션의 문제를 잘 드러낼 수 있는 이론체계라고 생각된다. 본 연구는 활동이론에 근거하여 거시적·미시적 관점에서 사회활동시스템 속에서의 박물관과 박물관 내에서의 활동시스템을 분석하고 이를 통해 박물관의 커뮤니케이션을 박물관 내부 활동시스템 간의 네트워크 실천, 박물관과 지역의 예술장(藝術場)이 연계된 네트워크 실천과 박물관과 학교가 연계된 네트워크 실천 모형을 구조화하여 제시하려 한다.

      • 건강한 성인에서 발병한 칸디다와 연관된 위궤양 1례

        박지훈,이상혁,김희,이재호,박성재,지삼룡,양성연,박은택,이연재,설상영,정정명,강미선 白中央醫療院 2005 仁濟醫學 Vol.26 No.1

        Fungus such as Candida albicans is a normal flora that is frequently found in the oral cavity, gastrointestinal tract, genitourinary tract, vaginal mucosa in a normal person. However, candida can cause opportunistic infection in an immune compromised host. Candidiasis has broad spectrum of disease from mucocutaneous infection to invasive or disseminated infection. But, it is rarely reported that candida is associaed with gastrointestinal tract disease in a healthy adult. The case of gastric ulcer associated with candida particularly in a health adult is reported with relevant literature.

      • 제 2형 당뇨병 환자에서 대사증후군의 유병률 및 관련요인의 특징

        박철진,박거운,박일구,신지혜,김진화,배학연,김상용 朝鮮大學校 附設 醫學硏究所 2007 The Medical Journal of Chosun University Vol.32 No.3

        Background: People with insulin resistance has a higher risk of developing cardiovascular disease. This leads to the importance in diagnosing metabolic syndrome. The incidence of metabolic syndrome has increased significantly in korea because of an increased population of obese people and also the incidence of DM. There have been many studies done on the incidence of metabolic syndrome in the general population. Therefore, the authors have designed this study to identify the incidence of metabolic syndrome in patients with type 2 DM and also the associated characteristics in that population. Methods: The study included 169 adults over the age of 20 (84 males and 85 females) admitted to the endocrinology department of Chosun University between Jan, 1st 2005 and May, 31st 2006. Out of the people diagnosed with type 2 DM people were excluded when any of the physical measurements (height, weight, blood pressure, abdominal circumference) and blood measurements (TG, HDL-cholesterol, fasting blood sugar) were insufficient and when the patient was taking any drugs other than anti-hy-pertensive agents and oral anti-diabetic agents. Obesity and the other risk factors were defined by the Asian-Pacific guideline and 2001 ATP III of NCEP, respectively. Result: The each prevalence according to the metabolic syndrome criteria of the type 2 DM patients showed low HDL cholesterolemia with the highest incidence of 57.4% followed by hypertng1yceridemia(52.0%), obesity(40.9%) and hypertension(33.0%). The each incidence of diagnostic criteria in metabolic syndrome according to sex was different, In males, hypertriglyceridemia was the highest with the incidence of 57.7% followed by low HDL-cho1estero1emia(49.5%), obesity(40.9%) and hypertension (30.0%). In women, the incidence were low HDL-cho1estero1emia(64.8%), hyperthg1yceridemia(47.6%), obesity(45.0%) and hypertension(36.0%), in a descending order. The analysis between the diagnosis of metabolic syndrome in type 2 DM patients and the criteria showed that hyperthglyceridemia (correlative value 0.575) had the highest correlation followed by low HDL-cholesterolemia (correlative value 0.446), obesity (correlative value 0.350) and hypertension (correlative value 0.410). All the correlations were statistically significant with a p-value less than 0.01. Conclusions: Type 2 DM is a important factor of metabolic syndrome based on insulin resistance. The control of blood glucose with prevention and early diagnosis of the other factors related to metabolic syndrome in type 2 DM is important for preventing cardiovascular complications.
