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.

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: The autonomic nervous system distributed throughout the stomach consists of adrenergic, cholinergic, and non-adrenergic, non-cholinergic (NANC) nerves. Of these, NANC nerve fibers are known to be distributed all throughout the gastrointestinal tract and they provide the main inhibitory nerve supply to the gut smooth muscle. NANC nerve is known to release neurotransrnitters such as nitric oxide (NO), adenosine 5-triphosphate (ATP) and vasoactive intestinal peptide (VIP). However, the effect produced by each of the NANC neurotransmitter depends on an animal species and parts of gastrointestinal tract. Therefore, this experiment applied electrical field stirnulation at the circular musc]e of a guinea pigs gastric fundus to observe any relation of NANC nerve in muscu]ar relaxation. Methods: The effect of ATP, VIP, and NO on muscle re)axation was determined through the electrical field stimulation, and each neurotrans- mitters ability to regulate the muscle relaxation was compared. Results: Muscle strips were relaxed in response to electrical field stimulation that was applied. The relaxation was not inhibited by atropine or guanethidine, but was completely inhibited by tetrodotoxin. The muscle relaxation caused by NANC nerve stimulation was inhibited by L-NNA, VIP antagonist, and suramin. L-NNA was the most potent inhibitor among them. The muscle relaxation caused by electrical field stimulation was not further inhibited by VIP antagonist after the pretreatment of L-NNA, however, it was further inhibited by L-NNA following the treatment of VIP antagonist. The electrically stimulaed induced muscle relaxation was almost complete]y abolished by coadministration of L-NNA with VIP antagonist and suramin, The exogenous VIP-induced muscle relaxation was not affected by presence or absence of L-NNA. Oxyhemoglobin or methylene blue treatment inhibited the muscle relaxation induced by electrical field stimulation. Conclusions: Non-adrenergic and non-cholinergic nerve has an inhibitory neurotransmission in a guinea pigs gastric fundus circular muscle and NO is the principal inhibitory neurotransmitter of NANC nerve. NO mediated muscle relaxation is thought to be associated with increase of cGMP in muscle cells. (Korean J Gastroen- terol 1997;29:2S9 - 300)

The tap water used in Seoul was found to be corrosive. Its corrosivity was effectively reduced by that the additions of alkali agent such as NaOH, Ca(OH)₂ and corrosion inhibitor such as H₃PO₄. For the corrosion test, carbon steel pipe 50 m long was exposed to the drinking water produced by a pilot plant at 36.5 ℃, similar to the existing process where it takes about 20 minutes to reduce the initial chlorine content of 0.5 ㎎/L to 0.05 ㎎/L. CO₂ and Ca(OH)₂ was added not only to control the Langelier index (LI) above -1.0 and but also, to increase the duration time of residual chlorine by about 6 times. The persistence effect of residual chlorine was in the order of H₃PO₄ > Ca(OH)₂ > NaOH. Measurements of weight loss showed that corrosion inhibition was effective in order of Ca (OH)₂ > H₃PO₄ > NaOH > no addition, where the concentrations of Ca(OH)₂ and phosphate were 5 ~ 10 ㎎/L (as Ca²⁺) and 1 ㎎/L (as PO₄^3-), respectively.

N/A The spastic pelvic floor syndrome is a functional disorder due to abnormal contraction in- stead of relaxation of the pelvic floor muscle during straining. This inhibits defecation and gives rise to constipation. We carried out the clinical and psychologic analysis, defecogram, electrophysiologic tests, and treatment in 17 patients with spastic pelvic floor syndrome. The mean age of patients was 48.2+10.1 years. The male to female ratio was 1:7.5. Prirnary com plaints were incomplete evacuation 82.3%, constipation 52.9%, tenesmus 41.2%, straining 41.2 %, and dysuria 29.4%. The patterns of personality using the MMPI showed somatization type in 7 cases and psychophysiologic reaction type in 4 cases. Defecogram revealed paradoxical contraction of puborectalis in 100.0% of cases,incomplete evacuation 76.5%, rectocele 58.8%, incontinence 17.6%, intussusception 5.9%, and excessive pelvic floor descent 5.9%. The ano- rectal angle in patients did not increase during straining and rernained about 90. The mean maximum resting and squeezing anal canal pressures were 94.4 + 48.4mmHg, and 136.4 + 28.8 mmHg. Seven patients(70.0%) were unable to expel a balloon. The pudendal neuropathy re- vealed in 4 patients(40.0%). Seven patients underwent a EMCr-based biofeedback therapy. Four among them(57.1%) had increased bowel frequency and improved the symptom of in- complete evacuation. In conclusion, careful history taking, physical examination and colorectal motility tests perrnit diagnosis of spastic pelvic floor syndrome. This disease is related with incoordination of pelvic floor muscle, so treatment should be aimed at restoration of normal muscle function through biofeedback.(Korean J Gastroenterol 1994; 26: 482 490)

N/A Objectives: As nonorganic, or functional factors play an important etiopathogenetic role in chronic constipation, we have reviewed functional tests on patients with chronic idiopathic constipation. Results of investigation and subsequent proper treatment are suggested. Methods: Clinical assessment, colonic transit, defecogram, anorectal manometry and pelvic floor electrophysiologic tests were performed in 30 patients with chronic idiopathic constipation, Results: 1) The ratio of male to female was 1:4, and the mean age was 48.2 years. Primary complaints were incomplete evacuation (83.3%), abdominal fullness (70.0%), abdominal pain (70.0%), rectal bleeding (43.3%), nausea (33.3%), tenesmus (33.3%) and dysuria (20.0%). Hemorrhoids and melanosis coli were present in 70.4% and 11.1% of the patients respectively at colonoscopy. The types of personality using the Minnesota Multiphasic Personality Inventory showed somatization 50.0% and psycho- physiological reaction 41.7%. 2) Colonic transit studies identified three patterns: normal transit 38.9%, colonic inertia 22.2%, pelvic outlet obstruction 16.7%, and mixed type 22.2%. The mean transit time of total colon was 56.4±5.0 hr. in colonic inertia and mixed type. 3) Defecogram revealed rectocele 77.8%, incomplete evacuation 48.1%, paradoxical contraction of puborectalis 40.7%, rectal intussusception 25.9%, parietal rectal rigidity 11.1%, and excessive pelvic floor descent 11.1%. 4) The mean minimal sensory volume, anal sphincter length, maximum resting and squeeze anal pressure was 47.9±17.5 ml, 3.9±0.9 cm, 104.3±17.9mmHg and 156.4±15.0mmHg respectively. The anorectal inhibitory reflex was intact in all patients. 5) Electrophysiologic studies suggested pudendal neuropathy in 5 patients (27.8%). 6) The patients were treated by drug therapy 83.3%, biofeedback therapy 10.0% and operation 6.7%. Conclusion: From the above results, systematic diagnostic evaluation and proper treatment for the patients with chronic idiopathic constipation in view of functional motility disorder are required and treatment can be helpful particularly when directed by a multidisciplinary team approach.

주민의 공원녹지의식에 따른 도시공원녹지확충 연구 : 수원시의 공원녹지사례 중심으로

박청인(Park Chung-In) 한국산림휴양학회 2010 한국산림휴양학회지 Vol.14 No.3

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 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.

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)
