This study analyzed the collaborative process in time series by dismantling the edit log big data of Wikipedia Korea, a representative online collaboration community, from early 2002 to 2019. Analysis elements were extracted from the document edit records, formatted in standardized XML, and analyzed using Python and R. The ways of editors' contribution, the characteristics of data contents, and the trend of document creation were explained by the analysis. An active contribution of a small set of editors and a loose participation of the majority were revealed. In addition, sociocultural characteristics that appear in online communities were also found in Wikipedia Korea. A new, diverse set of external resources is necessary to sustain the collective intelligence. An effort to settle new editors into the wikipedia community and an openness through circulation structure to avoid the exclusiveness of the management group are suggested.

Remodeling becomes the significant issue in the aspect of the resource recycling, because it does not demolishes the whole buildings, but a part of main structure. However, compared with new construction, remodeling has several problems of adding the repair and rehabilitation works, using the partial demolition method, and having difficulties of making decision due to disagreement between several owner organizations. BIM, which is the total solution for managing and producing information during whole life cycle of the buildings, seems to be the right solution for the way to address these issues. has a possibility for solving the problems. Therefore this paper provided the framework and database for applying the BIM in the remodeling, and proved the applicability of the BIM database in the remodeling project through the case studies.

As people pays more attention to remodeling as a method to effectively improve, maintain, and manage building properties, it is important to ensure the economic feasibility of remodeling compared to reconstruction, instead of focusing on systematic regulations. In order to identify core technologies, the study set criteria to survey cost of a remodeling project by analyzing current status of remodeling projects. Based on the criteria, the study calculated average construction cost for five remodeling projects that were conducted recently, compared the cost with new construction projects, and examined major level works that are essential in a remodeling project. Based on the major level works, the study conducted interviews with construction experts to draw core technologies in design, structure and construction of a remodeling project.

Improvement of productivity and efficient process management need to define the problem of the previous work. If it takes long time to gather necessary information, it becomes difficult to continuously manage processes to satisfy customers' needs and to enhance business efficiency. This paper proposes methods and a context awareness system for decision making to solve problems originated in management of manufacturing process through real-time information acquisition. We implement the context awareness by suggesting decision logics that automatically classify works with acquired information. And we also implement a system for case study which makes workers recognize problems and notifies instructions to them. Consistency between real object and stored data and continuous process monitoring with this system could find inefficient resources or delayed works, resolve them and improve processes efficiency.

The importance of demolition industry is becoming lager because of reusing and recycling of construction waste in current trend to pursue for sustainable development. As considering situation of the domestic housing construction and existing house, a scale of demolition industry is expecting to be increased continually. Therefore, for sustainable development is needed forecasting and managing rightly demolition waste to be producted at demolition phase. But, The development of model for estimating demolition waste is not sufficient in the country, also, the development of computer system for managing it rightly has not yet been created. In this study developed the estimating waste units for estimating demolition waste of an apartment and a house. A regression model for quantifying demolition waste easily is developed to do simulation again after making the estimating waste units through analyzing draws. This model is developed as a computer system for increasing application and then verified the reliability through field application. this regression model can quantify a sort of 22 demolition waste easily based on the size of the floor area and a number of units. This system is expected to quantify demolition waste easily which is producted during redevelopment and remodeling of existing house.

은행, 저축은행, 신용정보회사 등 금융기관에서는 채권관리 및 회수, 각종 우편물 발송 등의 업무처리를 위해 채무자 또는 고객의 최종 주소의 파악이 필요하다. 주소 파악을 위한 업무프로세스는 금융기관 직원이 채무자와 사실 관계를 증명하는 서류를 작성하고, 행정기관에 직접 방문하여 민원서류를 발급 받는 등 Off-line으로 이루어지고 있다. 이러한 민원서류 발급 업무량은 경제상황의 악화와 그에 따른 신용불량자의 대거 발생 등으로 인해 지속적으로 증대되고 있다. 따라서 행정전산망과 금융전산망을 서로 연결하여 신속하게 정보를 파악할 수 있도록 하는 주소 인증공동이용시스템(ACCESS, Address Certification Co-opErating SyStem)을 구축하는 것이 필요한 실정이다. 이에 본 연구에서는 ACCESS를 구축을 위한 설계를 통하여, 행정기관 민원서류 발급업무 담당자, 금융기관 해당업무 종사자 등의 업무를 대폭 줄임으로서 산업생산성을 제고 하는 방안을 제시하고자 한다. 또한 향후 행정전산망과 금융전산망의 연결체계에서 새롭게 구축될 다양한 정보서비스의 유형을 처리 할 수 있는 기반을 마련하여, 효율적인 정보의 공유와 유통 및 이를 통한 시너지효과를 창출하고, 정보자원의 활용 및 가치를 극대화하고자 한다.

This study used content analysis to examine the research methods in Library and Information Science journals from 1997 to 2001. Analyses measured research subjects, research method, data collection methods, data analysis methods, hypotheses, theories and research funds. Brief consideration is given to possible future methodological trends : web-based research methods, qualitative research, cooperation between academic society and librarians and research fundraising.

Recently, interests in subsidence hazard have been increased due to the underground construction such as subway construction and managements of abandoned mines. GIS analysis of subsidence hazard has a lot of advantages in handling of spatial data and managing database. For better result of GIS analysis, there are some necessities of modifying previous subsidence theory and model. To take surface profile into account allows the application of complicated topology. Furthermore. for 3-dimensional analysis. two subsidence profile curves that are perpendicular to each other should be considered simultaneously. Through these modifications, the model for subsidence analysis using GIS can be established. With ideal case of cavities and other conditions, GIS analysis was accomplished and meaningful results were produced. More realistic properties of cavity. soil layers, groundwater condition and topology will enable GIS analysis method to produce more reliable result and to widen the area of applications.

In this study, a survey was conducted on the required measurement and waterproofing performance for residential building underground structure leakage prevention system. According to the results of the survey, it has been determined that leakage problem is considered to be quite severe, and many respondents have agreed. The legal guidelines and regulation systems do not reflect properly on the environmental requirements or conditions, resulting in continued leakage problem. In regards to this, a standardized waterproofing technique that can be used in underground areas of residential structures is required as an obligation and the development of high performance waterproofing method that allows for wet concrete surface adhesion and a guideline, design and maintenance method that allows the control of overall situational control of leakage is required.
