Nowadays, the concept of outdoor campus is different from the past. U-Campus with a well-developed high-speed computer network is no longer a constraint on the campus interior and exterior spaces. From this point of view, today's large-scale university outdoor spaces need to be changed from a simple green space. The university campus outdoor spaces need to be changed into a new concept space. This study analyzed the changes in academic activities and preferences of college students who are users of university campus outdoor spaces and it is aimed at space planning that reflects the preference. The university campus should be remodified through changes in students' behaviors. Participants in this study were four different departments students (Social science, Physical education, Natural science and Engineering). The preference results of 17 items were analyzed. As a result of this preference analysis, we found that there is a difference in preference among students belonging to four different departments students. In conclusion, this study will propose that the preferences of each college should be considered in planning the outdoor rest spaces of university campus.

University campus is confronted with a variety of educational circumstances. U-Campus and the changes in students' academic activities demand a remodeling of university campus. The purpose of this study is planning direction for a remodeling space in university. This study in particular focus on indoor student lounges for the students. A survey asked students about a preference of indoor student lounges. Four preferences; the physical characteristics, preference of furnitures and lighting, preference of behaviors and preference of space programs are classified through the analysis on advanced studies. The results show not only students' preference but also a preference of each four different departments students; Social science, Physical education, Natural sciences and Engineering. In conclusion, this study will suggest a concrete plan for the future direction of the indoor student lounges at this point increased the importance of the university indoor student lounges.

N/A Gastric cancer is the most prevalent gastrointestinal tract malignancy in Korea. Although most effective treatment of gastric cancer is early detection and early resection of gastric cancer, but by the time the patient has symptoms, these tumors are usually advanced in stage. Gastric cancer staging methods for accessing surgical operability and resectability, the treatment planing and prognostic implications of gastric cancer patients are physical examination, liver function test, liver scan, abdominal ultrasonography, abdominal CT, angiography, lymphangiography, peritonioscopic examination, The reliability of physical examination, liver scan, abdominal ultrasonography and CT scan in preoperative staging of gastric cancer patients has been evaluated 77 patients with histopathologically proven stomach cancer (52 cases were performed ultrasonography, 24 cases were performed ultrasonography and CT scan). Who has admitted to department of internal medicine, college of Medicine, Han Yang university from December 1984 to June 1986. The results were as follows; 1) The mean age of gastric cancer was 56.6-year-old and the sex ratio of male to female was 3.3:1. 2) Preoperative staging of gastric cancer patients by physical examination and liver function test and UGI has no clinical significancy. 3) Liver scan, abdaminal ultrasonography and CT scan were 71.2% accurate, and 78% accurate, and 83.3% accurate, respectively, in detecting liver metastasis and sensitivity of liver scan, abdominal ultrasonography and CT scan in detecting liver metastasis were 77.7%, 34.3%, and 86.2% respectively (P<0.05). 4) Sensitivity of abdominal ultrasonography and CT scan in detecting lymph node metastasis were 20.3% and 65%, respectively (P<0.05). 5) Sensitivity of abdominal ultrasonography and CT scan in detecting other organs metastasis were 45% and 66.7%, respectively (P<0.05). 6) Metastasis to regional lymph node (14 patients), retroperitoneal lympho node, retrocrural lymph node, liver, pancrease, omentum and colon were well defined by CT scan than abdominal ultrasonography in 24 patients, 7) Diagnostic accuracy of CT scan staging was 66.7% (15/24) by correlation of surgical and pathological findings. 8) Although the usefulness of CT scan was limited in gastric wall-thick ness and differentiating lymph node metastasis from reactive lymph node hyperplasia, the pro-operative CT scan was useful in staging of gastric cancer and particularly in predicting metastasis to 1vmoh node and other organs.

N/A Background/Aims: Despite considerable advances in imaging technique and diagnostic tool, early diagnosis of pancreatic adenocarcinoma and differential diagnosis from chronic pancreatitis remain elusive. Mutations in K-ras oncogene at codon I are detected at 75 100% in pancreatic carcinornas and are believed to be a critical event in early stage of oncogenesis. As most pancreatic cancers are adenocarcinoma derived from the ductal epithelium, proliferating cancer cells ot the ductal nest may puss into pancreatic juice. Therefore the author attempted to detect K-ras mutations in DVA ohtained from pure pancreatic juice collected endoscopically as a novel noninvasive diagnostic method to detect pancreatic carcinoma. Methods: K-ras mutations were examined using the two-step polymerase chain reaction(PCR) combined with restriction enzyme digestion, followed by single strand conformation polymorphism(SSCP) analysis and direct sequencing. Results: Specific mutations of K-ras gene at codon 12 were found in seven of nine(77.8%) chict cell carcinonas by enriched PCR and SSCP method. K-ras mutations were not detected in the pancreatic juice frorn IO healthy control subjects, five patients with chronic pancreatitis, or two patients with mucinous cystadenoma. The most frequently observed type of mutations at codon 12 was G - C transversion(GCiT - CGT), resulting in alteration of glycine to arginine. There was no apparent correlation between the location, size or stage of the tumor and the detection rate of K-ras mutations at codon 12. Conclusions: Detection of K-ras mutation at codon 12 in pancreatic juice is a highly specific diagnostic modality for pancreatic ductal carcinoma and may be valuable for early detection of pancreatic carcinoma and differentiation between chronic pancreatitis and carcinoma.(Korean J Gastroenterol 1997;29:234-246)

N/A Background/Aims: Tissue biopsy from the biliary tree is difficult because of the focal and sclerotic or small annular nature, lower cellularity and well differentiated tumor. Biliary cytology is an effective tnethod of obtaining a tissue diagnosis for bile duct stricture, and thie diagnostic sensitivity of endoscopic brush cytology (EBC) is reported as between 40% and 70% for malignant bile duct strictures. In this study, we prospectively analyzed the diagnostic value of endoscopic brush cytology and aspiration bile cytology in patients with extrahepatic bile duct strictures. Methods: 30 patients with extrahepatic bile duct strictures diagnosed at endoscopic retrograde cholangiopancreatography underwent endoscopic brush cytology and aspiration bi]e cytology. 25 patients had malignant strictures and 5 patients had benign strictures, brushings were taken using a cytology brush(6Fr) or double lumen brush(8Fr) passed with a guide wire through the stricture. Results: The sensitivity and accuracy of brush cytology (60%; 15/25, 67%; 20/30) were significantly greater than bile cytology (20%; 5/25, 33%; 10/30). No false positive results were reported in brush cytology (specificity; 100%), but negative predictive value (33%; 5/15) was relatively low. There were no procedure related complications and the average sampling time was about five minutes. Conclusions: Endoscopic brush cytology is an effective, safe method of obtaining a tissue diagnosis for bile duct strictures, therefore EBC should be done routinely in bile duct strictures, but further prospective studies will be required to evaluate other new techniques such as endobiliary forceps biopsy or endoscopic fine needle aspiration or EBC with DNA flow cytometry because negative results do not exclude malignancy.(Korean J Gastroenterol 1996; 28: 832-844)
