The purpose of this study is to apply the process model of the pre-design stage to CPLM(Construction Project Life-cycle Management). Life-cycle consists of 4 stage; Pre-design, Design, Construction, Maintenance. Each stage has organic relations between front and rear stage. Therefore it is important to manage and use the information data of each stage. But these data are not carried to the next stage smoothly, especially at the pre-design stage. It is even vague to define the process of the pre-design stage. To carry and share the information well, this study defines Pre-design stage process and CPLM at first, VA-Cityplanner which is the development system of the pre-design process model is applied to CPLM for the smooth current of the data between participants.

BIM technology, based on 3D model of civil engineering structures, creates and manages information of the structures throughout four stages: Planning, design, construction, and maintenance. BIM is now used around the globe for improvement of the construction productivity. However, in order to expect the efficient engineering work, collaboration system between participants in a construction project is necessary. Therefore, in this paper BIM based CPLM (Construction project lifecycle management) system was designed and developed by analyzing the requirements of participants of a construction project. CPLM system offers an environment which enables the sharing and management of information according to the each stage of construction. CPLM is expected to aid cooperative decision-making during the overall construction process through the process innovation and the efficient data management.

This paper discusses on implementation methods for providing data exchange capability of the Construction Project Lifecycle Management System (CPLM). Because most information media currently used in the construction industry are computer files, the system must be capable of handling various file types; however, The goals of PLM cannot be achieved if the contents of the files are communicated freely, which can only be achieved using a standardized information model that has comprehensive coverage of all information produced within the projects (i.e., a BlM). Several methods of adopting the model are investigated here, and a transitional implementation method for K-IFC is suggested, in which a file-based exchange backed by the BlM can evolve into object-level transactions of the BIM with not only advanced data integrity and security, but also improved communications between the project participants.

The objective of this paper is to propose a conceptual framework of a BIM based collaboration supporting System, called Construction Project Life Cycle Management (CPLM). The framework of CPLM is proposed by reflecting the characteristics of the AEC industry such as deliverly methods, process, fragmentation, etc.. And it is a system intended to help project participants make better decisions and to facilitate coordination between various stakeholders in a project by providing virtual collaboration environment.

Purpose : As modern society has became more open, interest in healthy internal and external growth has increased, including that pertaining to penile length in children. A micropenis is defined as one where penile length is more than 2 SD (standard deviation) below the mean, and it can be traced back to chromosome and endocrine disorders. The authors executed this study to suggest guidelines for the study of the micropenis and standard information for penile length in Korean newborns. Methods : The subjects of this study were 168 male infants between 37 and 42 weeks of gestational age, none of whom had any complications during pregnancy or birth; each had been born in Daegu Fatima Hospital between February and June 2007. Penile length was measured using conventional stretched penile length measurement (CPLM) and syringe methods. Results : Penile length was $3.02{\pm}0.25cm$ (F=36.467, $R^2=0.180$, P<0.001) when measured with CPLM, and $3.29{\pm}0.26cm$ (F=9.149, $R^2=0.052$, P<0.001) with the syringe method. There was no statistically significant difference in the penile length of newborn infants as a result of taking measurements with the two methods, and both methods showed significance at 0.631 in terms of Pearson's correlation coefficient, at the level of P=0.01. Conclusion : In this study, penile length tended to be longer when gestational age was longer, and a micropenis can be assumed to be one less than 2.5 cm using CPLM and less than 2.8 cm using the syringe method. In the case of a concealed penis, the syringe method is helpful. When a micropenis is assumed, close observation by outpatient department personnel, and additional endocrine and chromosome studies should be undertaken after sufficiently consulting the parents.

An IFC Server is a database management system that stores data complying with a standard data format, called IFC, and keeps track of data transactions, modifications, and deletions. It plays a role as an information hub for storing and sharing information between various parties involved in construction projects. There have been several efforts to develop an IFC Server, however, they suffered from slow performance and long transaction time due to a complex mapping process between IFC files and relational database structures. In this study, we aim to develop an IFC Server using an object-relational database system. Since IFC has an object-flavored data structure, we expect to have a simpler and faster mapping process from IFC to the IFC Server. This paper reviews existing studies and describes the overall framework of the OR-IFC Server.

In order to develop VirtuAlmighty system, CPDM (construction project data management) and CPLM (construction project lifecycle management) model must be settled beforehand. Because most of information systems based on 3D-Design have its own database and business process. So, our team will develop collaboration management architecture of construction process for Decision Support based on PLM (Project Life-cycle Management). This architecture with business processes and Database can be used in process develop, process monitoring with many stakeholders of project, process change management, and so on.

Construction process works in sequence order and there are many different software for managing project and activity. So, there are many limitations such as in the stage of activity data loss can occur, in each stage concurrent cannot operate in construction industry. In order to solve these problem, agents have to cooperate each other and they need to share of data. Therefore, the purpose of this paper is to develop a process model and the process model will be use in the future to make Construction Project Life-Cycle Management based on concept of PLM(Product Life cycle Management) in the manufacturing industry, CE(Concurrent Engineering) and BlM(Building Information Modeling)
