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.

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.

With the increasing interest in green building and BIM, many studies on BIM-based energy simulation are being conducted in Korean AEC industry recently. One of the biggest issues in current studies is the trouble with interoperability of data between BIM modeling software and BIM-based energy simulation software. The purpose of this study is to establish a Proposition and Application of Mapping System for Input Data between Open BIM Data and Building Energy Simulation Software. For this, the authors analyzed various BIM-based energy software after the overview of Open BIM and energy simulation. In following phases, a mapping system was Proposed first, and an integrated material library was also generated through the system. Finally, the authors developed a IDF-Convertor which allows management, exchange, and sharing of data between IFC and BIM-based energy simulation software. The result of this study would enable the energy simulation using IFC format, which might be considered difficult before. The use of IFC would allow energy software to utilize much data from other fields as well as material data, and so, help energy simulation advance in the future.

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.

There are many researches to make low-energy building. Lots of them focus on facility systems and insulation performance of building materials. However, not only systematic solutions but also approaches in early design stages are important to reduce energy consumption. Using BIM(Building Information Modelling) is considered as an effective and efficient way to simulate building energy and decide alternatives than traditional energy simulation because BIM based energy simulation makes to reduce much time for energy modeling. This study focuses on development of optimized geometry for super tall office buildings in Seoul, Korea. Specifically, length to width ratio and building orientation are main topics of this study because these two topics are the most basic and preceding factors deciding mass design. In this study, Revit MEP 2011 and Ecotect Analysis 2011 are used to make case models and calculate energy load in early design stages. Energy properties of material abide by Korean Standards for Energy Conservation in Building, Korean Guideline for Energy Conservation in Public Office and ASHRAE Standard in USA. This study presents best length to width ratio of plan and optimized orientation by evaluating the case models. Furthermore, this study suggests what should be considered for each case to decrease energy load.

This research aims to find information level-based system for building information management about each design stage. Even though BIM model is built for the design aspect, it is difficult that the BIM data are utilized in the next process such as construction stage or analyzation stage. In order to accumulate building information and to reduce the leakage of building information, various researches and projects for exchanging information such as COBie and SPie are being undertaken in many countries. This research analyzes COBie, which is the de facto standard in US and UK, and suggests ways of adopting this format in the Korean construction practically. In addition, authors suggest the COBie-based new criteria and defines contents and roles in each stage for more effective application of the analyzed results. Pre-checking modules are also developed to validate the data extracted based on suggested Information-level in six stages of building design. Through the suggested criterion, managed information in each construction phase are verified explicitly and the accumulated information enables the Building Information Model to apply more in various design phases.

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)

With the increasing demands of BIM design in Korean construction industry, it becomes an important issue to develop a proper standard of design fee for BIM. For now, many architects who are asked to design with BIM tools and produce BIM data with high quality are suffering from the lack of the new standard for the fee and necessary studies about it. The conventional standard without considering additional works for BIM design results relative fee declines and so, decrease of design quality. This study started with analyses of foreign guidelines and regulations for BIM design to learn their ways of dealing with the changing design fee. After comparing its results with current Korean situation, the study also conducted surveys to hear the opinions of Korean professionals. In the end of the paper, some troubles of conventional approaches are pointed out as a result of those researches, and considerable factors for the proper direction of a BIM design fee standard are suggested. It would work as an essential guideline for the further studies which try to establish more accurate and practical standards in the future.
