Elevated linear parks have the potential to support the ecological stability, city amenity, cultural opportunity, and health benefits of urban dwellers; these are increasingly becoming an integral part of the urban infrastructure. Due to structural limitations in space, linear parks need to be planned to increase the value of green space. This study was aimed at advancing urban planning techniques for increasing the value of elevated linear parks, by comparing the Seoullo7017 with the Promenade plantee and the Highline. Planning characteristics of these green spaces were analyzed from the perspectives of physical planning factors, amenity values for users, and management systems. Field surveys and virtual tools were used to investigate the current characteristics of these parks, in addition to the literature survey. From the analysis of planning factors, amenity values, and management in the three linear parks, following important recommendations were made in order to promote the values of these parks: (a) diversify planting design for increasing the diversity of green space in a narrow area; (b) bring in various forms of amenities to promote the quality of users' experience; and (c) establish community-based management systems for enhancing regional competitiveness and profit sharing in urban regeneration projects.

도시에 있어서 공원녹지는 도시의 구조적, 사회적 환경을 개선하는 다양한 기능이 있다. 본 연구는 도시의 공원녹지계획이 도시환경의 개선에 관한 연구이다. 지금까지 도시에 있어서 공원녹지계획의 대부분은 녹지의 양의 증대를 목적으로 실시되어 왔다. 그러나 한정된 도시공간에서 공원녹지의 물리적인 확충은 토지의 확보가 어려워 곤란한 것이 현실이다. 그럼으로 본 연구에서는 기존의 공원녹지와 녹지에 대한 이용자평가를 통해 향후 공원녹지계획상의 학문적 근거이론의 확인과 실무적 사례 구축에 기여한다는 의의를 가진다. 본 연구에서는 공원녹지의 구성과 배치특성에 균등배치와 집약배치의 각기 다른 특성을 가진 일본의 타마뉴타운의 두 지구를 선택하여 319명의 주민에게 설문조사를 실시하여 t-검정, 요인분석, 중회귀분석의 통계방법을 활용하여 분석하였다. 연구의 결과로서 공원녹지의 구성과 배치가 다른 두 지구의 만족도평가요인은 차이가 확인되지 않았으나, 각 지구내의 세부평가요인에 있어서는 차이가 확인되었다. 만족도에 영향을 미치는 요인으로는 공원녹지의 질, 주변녹지의 질, 접근성, 차도분리의 요인이 두 지구의 공통요인인 것이 확인되었다. 공원녹지가 집약배치된 지구에서는 만족도평가요인에 있어서 주변녹지의 질이 만족도에 가장 큰 영향을 미치며, 공원녹지가 균등배치된 지구에서는 만족도평가요인에 있어서 공원녹지를 이용하는 보행공간의 차도분리가 만족도에 가장 큰 영향을 미치는 것이 확인되었다. Parks and green spaces have various functions for improving urban physical and social environments. Urban parks and green space planning have been applied in this study for the purpose of enhancing the urban environment. The most popular method for urban parks and green space planning is incrementing the quantity of parks and green spaces. However, it may not be possible to designate new parks and green spaces in a large city because of the difficulty of obtaining land. This study explores how urban parks and green space planning produces better quality urban environments without having to designate new parks and green spaces. The study evaluates existing parks and green spaces according to the satisfaction of the users. This evaluation could be a useful tool for those planning urban parks and green space systems. The study was performed in Tama Newtown, Japan, within two districts with two distinct characteristics of park systems: concentration and equality arrangement forms. For comparison, on-site questionnaires were used, with 319 residents in the area responding to the study. The data was collected and analyzed, using t-test, factor analysis, and multiple regression methods. The study found there was no difference in satisfaction factors be tween the two districts. However, differences were found within each of the districts, depending on parks and green space components. For example, the quality of green space was the most important factor for the district with a planned concentration arrangement form of parks and green spaces, but, separation of the pedestrian and vehicular systems was the most important factor in the district with a planned equality arrangement form of park system. Factors affecting the satisfaction of parks and green spaces that were common between the two sites were: accessibility, quality of park, quality of green space, and separation of pedestrian and vehicular traffics.

본 연구는 도시공원녹지의 확충에 대하여 수요자인 주민의 공원녹지에 대한 의식을 반영한 계획이 모색될 수 있도록 기초적 자료구축에 목적이 있다. 기초적 자료는 주민이 공원녹지에 대한 기본적 개념, 이용행태, 정책참여의사등으로 도시공원녹지 전반에 대한 주민의 평가를 분석함으로서 구축되었다. 학문적으로는 공원녹지계획의 상향식 계획의 요인과 도시공원녹지에 대한 이용자 특성 연구의 근거이론 구축에 부가적 목적을 두고 있다. 수원시를 연구대상지로 하여 총 733인의 표본의 추출로 면접조사가 이루어진 결과, 아래와 같은 연구의 결과를 얻었다. 수원시공원녹지는 산책과 휴식을 위하여 가족이용자가 가장 많았으며 주로 이용되는 시설은 근린공원과 체육시설지로 분석되었다. 공원녹지에 대한 평가는 도시전체의 환경적 질의 관점이 아니라 주민의 개개인의 삶의 질의 관점에서 평가하였고, 정책당국의 공원녹지정책에는 경제적 참여보다는 행동적 참여를 더 지지하였다. 결론적으로 공원녹지의 확충은 주민의 의견이 반영되는 상향식 의사결정에 의한 방법이 더욱 더 모색되어야 할 것이다. This study aims to establish ground theory and database for expansion of urban park and green belt based on residents’ attitude. The residents’ attitude of park and green belt was evaluated by various factors such as basic concept of park, usage pattern, participation in city government policy. For this study, The interview method was applied to 733 individuals who were collected as the study sample. The results of the study are follows. Most of urban residents use neighborhood parks and sports complex for relaxation and strolling. The urban residents evaluated urban park and green belt by not a holistic thought of urban environment, but individual view of quality of life. The urban residents prefer to political and participational surport rather than financial support for city government policy of urban park and green belt. In conclusion, the expansion of urban park and green belt should be received a down-up decision making system for reflecting urban residents’ opinions.

N/A Melanosis coli associated with ingestion of anthraquinone compounds in laxatives is due to accumulation of macrophages containing brown lipofuscin-like pigments in the lamina propria. We analyzed the clinical, endoscopic, and pathologic findings and colonic motor functions of melanosis coli and performed electronmicroscopic study to know the ultrastructural changes of neural elements. We studied 13 cases (mean age 48.1 +- 18.5 years, male to female cases 6:7). The vegetable laxatives containing anthraquinone derivatives, aloe or bisacodyl were used mainly and the mean duration of laxative abuse was l.5 +- 1.2 years. Endoscopically, dark brownish mucosal disoloration showed polyhedral forms divided by fine striae of lighter color. Melanosis was more intense in the more oral part of the bowel. Pathologically, no relationship was found between grade of melanosis and kind of drugs, daily dose, or durat.ion of addiction. Ultrastructural features on nerve structure were ballooning of axon. reduction of nerve specific cell organelles, and increased lysosomal activity. The alterations of these neural elements are assumed to he associated with impaired colonic motility. In conclusion, vegetable laxatives such as aloe, seem to be an important causes of melanosis coli in Korea. melanosis coli have a tendency to damage nerve fibers. We should avoid laxative abuse in order to prevent pragressing to cathartic colon.

N/A Primary hepatocellular carcinoma(HCC) is one of the most common malignancies in Korea due mainly to high incidence of chronic hepatitis B virus infection. Most of the HCC are inoperable even at first presentation. So chemotherapy could be one of the major therapeutic modalities, but HCC is seldom chemosensitive. This type of chemoresistance is explainesd by high level of expression of multidrug resistance(MDR) gene and p-glycoprotein. We initiated this study to establish the in vitro model of drug selection and combination for HCC. Three human HCC cell lines and five cytotoxic drugs were used. MTT assays for cytotoxicity test were performed with single chemotherapeutic agent and various two drug combinations. Slot blot analysis for measuring the expression levels or MDR1 RNA was performed and demon strated that 2 HCC lines show moderate to high degree of MDRI expression, The ranges of drug concetration which causes 50% inhibition of the cell lines(IC50) are in the clinically achievable concentrations for the 5-fluorouracil in two HCC lines, and adriamycin in one cell line. Two cell lines which showed positive MDRI exression were resistant to adriamycin. But all three cell lines were sensitive to etoposide irrespective of MDR1 expression. In thelinically achievable concentration ranges those we tested, singnificantly improved cytotoxic effects are demonstrated in combinations of etoposide plus cisplatin, and etoposide plus mitomycin-C out of 10 possible two drug combinations. These data indicate the need for in vivo trials with the combination chemotherapy of etoposide plus cisplatin or etoposide plus mitomycin-C for HCC.

N/A Objectives: This study was designed to estimate the prevalence of Helicobacter Pylori infection in a healthy population in Korea and correlate between H. Pylori infection and serum pepsinogen levels as markers of gastritis and atrophic gastritis. Methods: We collected sera obtained form 104 children and 173 adult who had no gastrointestinal symptoms and measured specific IgG antibodies against H. Pylori by Bio-Rad G. A. P test. Serum pepsinogen 1 and 2 concentrations were determined by radioimmunoassay. Results: 1) The frequency of H. Pylori infection increased with age and was more than 80% over age 40. 2) Serum pepsinogen 1 and 2 concentrations in the healthy population were increased with age, while the serum pepsinogen 1/2 ratio decreased. 3) There were no significant statistical differences between the titre of specific IgG antibodies against H. Pylori and serum pepsinogens. Conclusion: The data from this study suggested that the prevalence of Helicobacter Pylori infection increased with age and serum pepsinogen levels were related to the presence or absence of H. Pylori infection. We conclude that H. Pylori infection is one of the factors which helps develop atrophic gastritis, the precursor lesion of gastric cancer.

Purpose: Parenteral nutrition (PN) is a standard supportive care for pediatric patients undergoing hematopoietic stem cell transplantation (HSCT) in Samsung Medical Center. The objective of this study was to identify the factors associated with the length of hospital stay (LOS) in pediatric HSCT patients administrating PN routinely. Methods: This was a retrospective study for 128 pediatric HSCT patients from Aug. 2008 to Dec. 2009. Demographics, nutrition status on the first report in the nutrition support team, calories and nutrients supplied, PN duration, LOS, PN-induced complications, and laboratory data were collected from electronic medical records. Multivariate analyses were conducted to identify factors associated with LOS. Results: The median age of registered patients was 70 months (range 6∼239 months). Twenty-three patients (18.0%) were malnourished moderately to severely when PN was started. Number of autologous HSCT was larger than allogeneic HSCT (87 vs 41). In children undergoing HSCT, LOS was significantly correlated with PN duration (P<0.001) and graft type (P<0.001). Especially, in autologous peripheral blood stem cell transplantation (PBSCT), malnourished patients at the beginning of PN were shown the tendency to increase LOS (P=0.024) and PN duration (P=0.043). Conclusion: In pediatric HSCT patients administrating PN routinely, LOS was associated with a graft type of HSCT and PN duration. Especially for autologous PBSCT patients, the nutrition status at the beginning of PN had the influence on LOS and PN duration. During the peri-HSCT period, careful nutrition monitoring can prevent malnutrition, decrease PN duration, and shorten LOS. (JKSPEN 2011;4(1):1-6)

N/A Background/Aims: Alteration in the p53 tumor suppressor gene are involved in the pathogenesis of diverse human cancer. Immunohistochemical detection of the p53 protein has been strongly correlated with rnutations in the p53 gene. Although p53 overexpression or mutation have been elucidated in a variety of cancers, there has been no study in pancreatic cancer in Korea. The purpose of this study is to evaluate the expression rate of p53 protein in pancreatic cancer. In addition, we attempted to clarify the association between expression of p53 and clinicopathologic features including survival. Methods: Using immunohistochemistry with monoclonal antibody to p53(Zymed Lab. Clone No. BP53-12), we exained 47 formalin-fixed paraffin-embedded tissues of pancreatic cancer(39 intraductal adenocarcinoma, 8 rnucinous adenocarcinoma) for overexpres- sion of p53 gene product. Results: Positive nuclear p53 immunoreativity was detected in 44.6% of pancreatic cancer. No clear correlation was found between p53-positive immunostaining and clinicopathologic features such as age, sex, tumor size, location, histologic type, differentiation of tumor cells and stage of tumnor, etc. The mean duration of survival was 8.6 months in the group of p53 positive and 9.6 months in the group of p53 negative and no difference was noted between two groups. Conclusions: These results suggest that mutation of p53 tumor suppressor gene may play a role in the pathogenesis of pancreatic cancer. However there was no correlation between the presence of p53 overexpression and clinicopathologic features or survival. (Korean J Gastroenterol 1997; 30:98 - 102)

Enlargement of street tree planting area is the proper and effective solution to reduce carbon dioxide. This solution bases on the ability of carbon storage and uptake by tree metabolism. However, the circumstance of road side has fatal disadvantages in tree metabolism such as growth and maturity because cutting and filling of roadsides cause unnatural soil composition. In this point, early rootage of street tree is the main factor of reducing carbon dioxide. This study aimed to find a appropriate transplantation planting method for sound and rapid rootage of street tree. For the study, Korean Mountain Ash(Sorbus alnifolia) were used for experimental groups. The groups were categorized by three groups such as trees produced on container with mulching treatment, trees produced in outdoor with mulching treatment, trees produced on container with weeding treatment. Each group consisted 10 trees with same size and transplanted in experimental site. Five months after transplanting, each group was estimated the biomass and carbon storage through a direct harvesting method. According to results of the study, the carbon storage of trees produced on container with mulching treatment is 42% more than trees produced in outdoor with mulching treatment. And the carbon storage of trees produced on container with mulching treatment is 19.5% more than trees produced on container with weeding treatment. These results may imply that transplantation of container produced tree with mulching treatment is the most rapid rootage among other groups. The weeding treatment is more effective than mulching treatment for rapid rootage of street trees.
