Since Han-ok, the traditional Korean-style house, is composed with combinations of complex components in various shapes and sizes, it is essential to categorize the components into several types for digitalization of Han-ok information. This study applied feature-based classification using BIM parametric modelling methods. After investigating ‘Parameter and Formula relations’, ‘Parametric description’ and ‘Instance diagram’ of Han-ok components, the study established XML libraries for the parametric modelling of open BIM. The IFC-XML libraries include parametric and properties information as well as the geometric information of Han-ok. For the combination of parametric and non-parametric geometry, the study also suggested a new methodology of using ‘comments’ inside IFC, which enabled interworking between IFC and XML. A prototype of BIM browsing module was developed in the last phase of this study to validate the conformance of the IFC-XML libraries. This integrated browser for Han-ok allows the users, both experts and non-experts, to check and manipulate Han-ok component fabrication by changing specific parameters promptly. The browser successfully showed automatic changes of all related Han-ok elements in accordance with the parameters, relationships and formulas of components.

It is getting more difficult to assure reliable design quality in the recent construction industry with increasing large and complex projects. Open BIM has been introduced to solve this problem by managing and integrating enormous amount of information produced in the process of such projects. This study tries to clarify the methods of effective data management and design quality check for super-tall buildings in the BIM Environment. It demands identification of quality control target and examination of various requirements for quality control standards. The study suggests the process and methodology of the quality control in the early period of super-tall buildings design by developing a checklist reflecting domestic rules and regulations. The checklist is verified through sample tests in a rule-based software, SMC. The effective design quality assurance using Open BIM, which is the aim of this study, would improve the basic quality and performance of the super-tall buildings constructed in reality.

Background/Aims: Use of nonsteroidal anti-inflammatory drugs (NSAIDs) is known to be associated with a high incidence of upper gastrointestinal tract bleeding in the elderly. Increase in prevalence of Helicobacter pylori (H. pylori) infection according to age, implicates that an interaction between use of NSAIDs and H. pylori infection may explain the higher incidence of ulcer complications in the elderly. In the present study, we analysed risk factors existed in peptic ulcer patients with upper gastrointestinal bleeding. Methods: A retrospective study was performed for 420 consecutive peptic ulcer patients (bleeding: 98, nonbleeding: 322). The bleeding group had bleeding symptoms and endoscopic stigmata of bleeding. Use of NSAIDs was evaluated by interview and H. pylori infection was confirmed by endoscopic biopsy specimens and CLO test in all cases. Results: The rates of duodenal ulcer were 62.5% in bleeding group and 50.5% in nonbleeding group (p<0.05). NSAIDs and H. pylori-infection didn't show a significant correlation with bleeding (p>0.05). However, CagA showed a positive correlation with the peptic ulcer bleeding, especially gastric ulcer bleeding (p<0.05). Conclusions: In peptic ulcer patients, duodenal ulcer is more prone to bleeding than gastric ulcer. Use of NSAIDs doesn't increase the risk of upper gastrointestinal bleeding. Location of ulcer and CagA positivity seem to be risk factors of upper gastrointestinal bleeding. (Kor J Gastroenterol 2000;35:178 - 185)

Background/Aims: This study was performed to characterize the mode of cholesterol transport in human gallbladder bile with cholesterol gallstone. Methods: Subjects were 29 patients with cholesterol gallstone, and controls were 18 patients without gallstone who received surgery for gastric cancer. CsCl density gradient ultracentrifugation was used to separate vesicles and micelles. Each fraction was analysed by transmission electron microscopy and enzymatic determination. Results: Ultracentrifugation separated the gallbladder bile into the vesicular fraction (a low buoyant density of <1.05 g/mL) and micelles (a buoyant density of >1.15 g/mL). In the electron microscopy, the vesicles consisted of macromolecular aggregate, which were spherical in shape and were measured 1000 Å in diameter. In comparison with the controls, the vesicular cholesterol concentration was significantly high in patients with gallstone and the ratio of micelle/vesicular cholesterol concentration was significantly low in patients with gallstone. Conclusions: This study shows the importance of vesicular cholesterol in the patients with cholesterol gallstone, and supports that the formation of cholesterol gallstone is directly related to the concentration of cholesterol transported in vesicle.

To improve the effectiveness of BIM, the purpose of using BIM in project should be determined at first. Only after the survey of BIM tools should be performed and finally, the BIM usage process should be established according to the purpose. BIM can be also applied and may be useful in remodeling project, however, there are few cases and studies of applying BIM in remodeling project. Due to the high rent fees, in general, it is preferred that in the central districted area, the deteriorated offices are remodeled with resident status to retain lease income even during the construction period. Therefore applying BIM in Remodeling Project in Resident Status will be more necessary. When BIM is applied, such as 3D Modeling, Crash Check, 4D Simulation etc., in Remodeling Project in Resident Status, the restrictions of residents and complexity of demolished elements, remained elements and new elements should be considered. So, this study suggests a BIM methodology for Remodeling Project in Resident Status, which has consideration for characters of Remodeling Project in Resident Status such as resident’s migration plan, facility operation plan and temporary facility plan.

Background/Aims: Hyperplasia or dysplasia of pancreatic duct epithelium has been frequently found in the pancreas of pancreatic cancer or chronic pancreatitis. We hypothesized that ductal hyperplasia and dysplasia in the pancreas represent precursor lesions of cancer. Methods: We examined the expression of Ki-67, CEA, p53, K-γαs using the methods of H&E staining and immunohistochemical staining for 11 pancreatic cancer and 12 chronic pancreatitis specimens. For the specimens of pancreatic cancer, we classified the tissue into normal (n=7), ductal hyperplasia (n=3), dysplasia (n=4), and cancer lesion (n=ll). The tissue of chronic pancreatitis were also divided into normal (n=10), ductal hyperplasia (n=4), and dysplasia (n=5). Results: In pancreatic cancer, the Ki-67 index was 3.73±3.58 in normal site, 6.62±4.39 in ductal hyperplasia, 13.47±4.02 in dysplasia, and 37.03±10.05 in cancer tissue (p<0.05). In this study, the expression of p53 protein was observed in 78% of dysplasia and 91% of carcinoma cells but not in normal ducts and ductal hyperplasia. K-γαs was expressed in 33% of ductal hyperplasia, 67% of dysplasia, and 80% of cancer tissue but not in normal ducts. Conclusions: These data support the hypothesis that ductal hyperplasia and dysplasia of the pancreas represent precursor lesions of cancer. These results need further evaluation of molecular study of oncogenes. (Korean J Gastroenterol 2001;37:370-378)

Background/Aims: Clinical outcome of Helicobacter pylori (H. pylori) infection may be associated with specific virulence-related bacterial genotypes. The present study aimed to assess the relationship between the H. pylori virulence factors such as cagA, vacA, iceA and severity of upper gastrointestinal diseases. Methods: PCR was used to examine cagA, vacA, and iceA genotypes of H. pylori isolates obtained from 92 infected patients with different clinical presentations (14 cases of nonulcer dyspepsia, 26 cases of gastric ulcer, 30 cases of duodenal ulcer, 22 cases of gastric cancer). If sl was positive, DNA sequence was analyzed for its subtype. Results: The positive rate of cagA varies from 78.6% to 96.7% in the clinical subcategories. The positive rates of iceA1 and iceA2 were 88.5% and 0% in patients with gastric ulcer, 86.7% and 3.3% in patients with duodenal ulcer, 72.7% and 13.6% in patients with gastric cancer, and 92.9% and 0% in patients with nonulcer dyspepsia, respectively. No significant difference was found in the prevalence of cagA and iceA among these groups. The vacA genotype slc and ml were predominant in most subjects irrespective of the clinical outcome and we could not find slb and s2 subtypes. The genotype of cagA+ iceAl vacA slc-ml was predominant in Korean H. pylori strains. Conclusions: We could not confirm the previous reports of relationship between the cagA, vacA, iceA status and clinical outcome of patients with upper gastrointestinal diseases. Further study is needed to examine the specificity of H. pylori strains in Koreans. (Korean J Gastroenterol 2001;38:89-97)

Recently, the needs for sharing and exchanging drawing information between 2D and 3D CAD data in complex engineering fields are well recognized throughout the construction industries. The purpose of this study is to develop product model-based information framework for exchange and sharing of CAD drawing information between 2D and 3D CAD data in complex engineering fields. The current IFC2×2 model has the model space elements definitions to represent 2D drawing but not the paper space elements definitions. Therefore, it is necessary to extend the current IFC model to include the paper space elements for complex products. The study has been developed 1) IFC paper space extension model, 2) information framework to enable sharing and exchange of product model by adding various information factors, 3) the standard APIs and an IFC2DBrowser.
