Background: Facility management (FM) is an important phase in the building lifecycle. Although building information modeling (BIM) technology has been widely used in the design and construction phase, efforts to transfer information to the FM phase are still in the nascent stage. A good BIM-to-FM tool should be able to inherit and integrate the building information built in the design and construction phase as well as be able to provide a platform for managers to browse the information, discuss potential problems, and arrange maintenance work. Methods: In this research, a BIM interactive collaboration system for FM is designed and implemented. Two modules were developed for optimizing the BIM system in the FM phase: the data arrangement module, which has functionalities of data importing and processing, and the data presentation module, which provides functionalities of data revealing and collaboration. Result: From the results of an accessibility analysis, we verified that the developed system, V3DM+, can be implemented on real projects. Managers can use V3DM+ to support operation and maintenance of buildings. Moreover, a web-based platform allows users to manage facilities intuitively without investing on professionals or specialized software. Concluding: The proposed system, V3DM+, provides a data arrangement module to integrate building information constructed by various types of commercial software and present them in a visual manner. The user can find the required information, initiate a discussion on an issue, or arrange operation and maintenance tasks directly on this system.

A strategy based on postcolumn electrophoretic mobility control (EMC) was developed to alleviate the adverse effect of trifluoroacetic acid (TFA) on the liquid chromatography-mass spectrometry (LC-MS) analysis of peptides. The device created to achieve this goal consisted of a poly(dimethylsiloxane) (PDMS)-based junction reservoir, a short connecting capillary, and an electrospray ionization (ESI) sprayer connected to the outlet of the high-performance liquid chromatography (HPLC) column. By apply different voltages to the junction reservoir and the ESI emitter, an electric field was created across the connecting capillary. Due to the electric field, positively charged peptides migrated toward the ESI sprayer, whereas TFA anions remained in the junction reservoir and were removed from the ionization process. Because TFA did not enter the ESI source, ion suppression from TFA was alleviated. Operation of the postcolumn device was optimized using a peptide standard mixture. Under optimized conditions, signals for the peptides were enhanced 9-35-fold without a compromise in separation efficiency. The optimized conditions were also applied to the LC-MS analysis of a tryptic digest of bovine serum albumin.
