  • BIM technologies store, share and integrate the information produced in each sector of the construction industry. From this point on, it increases the efficiency of the work. Currently, quantity take-off and process schedule are derived separately based on BIM technology. When calculating the quantity by process, relevant information shall be collected, reinterpreted, and reevaluated as required by the practice. The purpose of this study is to develop an integrated process and quantity management system through BIM collaboration and to build prototypes for steel structures. The main research is to build a construction BIM model for steel structures and a process BIM model through BIM collaboration. Furthermore, necessary information was selected and processed according to the user's needs for integrated management. Relevant integration outcomes are visualized graphically to maximize utilization. Through these studies, a system for integrated control of processes and supplies is provided, and the results are expected to contribute to the improvement of working efficiency and are easily and quickly reflected in design change and process change. In this study, we intended to enhance the usability of information by linking process schedules with quantity calculations based on BIM. Thus, the process for integrated control of the quantity of structural components by process unit and the BIM based schedule information was established. In addition, the efficiency of the information link of the integrated management system was considered for design changes and process schedule changes.

  • The purpose of this study is to analyze the patterns and characteristics of changes in integrated process skills during the process of science high school students' inquiry by using group-based trajectory modeling. 59 students participated in this study. Three hypothetico-deductive inquiry tasks were used as an intervention activity. We asked science high school students to perform those three tasks sequentially and to generate reports of the process and results. We evaluated students' reports by four elements (designing inquiry, collecting data, analyzing data, and forming conclusion) of the integrated process skills according to the scoring rubric developed by Lee and Park (2017), and analyzed the level of changes in integrated process skills in those three inquiry tasks by using group-based trajectory modeling. In addition, we analyzed the characteristics of changes in integrated process skills from several perspectives. The findings are as follows: First, concerning the change patterns of students' integrated process skills, all of the four elements were classified into two groups, but the change patterns were very different by elements. Second, regarding the change characteristics of students' integrated process skills, we found the context-dependency of integrated process skills, variation of learning progression for integrated process skills, and jaggedness of integrated process skills level. Based on these findings, we suggested that a couple of ways be sought to improve the integrated process skills of science high school students.

  • As AEC(architecture, engineering and construction) industry becomes larger and more complex, much information is going into each part and phase. Therefore, the existing building design process has to change and collaboration is emphasized among participants in various fields. The purpose of this study is to compare and analyze existing building design process and integrated building design process based on BIM using a IDEF0 methodology. And then, it establishes a desirable domestic integrated building design process application plan focusing on the design phase of domestic cases. As a result of analysis, flowing conclusions are included ; Firstly, problems occur on the existing building design process that are accomplished with focusing on the outcome. It makes much errors because of 2D-based information. Another problems is that collaboration doesn't go on smoothly. But, integrated building design process is accomplished with the collaboration and the coordination which pursues change and perfects cooperation. Secondly, BIM is a process of effecting optimum integrating, re-using information, and expense reduction throughout the life-cycle of a building. Moreover, it establishes a basis for the integrated building design process to build a collaboration system.

  • The aim of this study was to optimize the ozonation and ceramic membrane integrated process for greywater reclamation. The integrated process is a repeated sequential process of filtration and backwash with the same ceramic membrane. Also, this study used ozone and oxygen gas for the backwashing process to compare backwashing efficiency. The study results revealed that the optimum filtration and backwash time for the process was 10 minutes each when comparing the filtrate flow and membrane recovery rate. The integrated process was operated at three different operating conditions with i) 10 minutes for filtration and 10 minutes for ozonation, ii) 10 minutes for filtration and 10 minute for oxygen aeration, and iii) continuous filtration without any aeration for synthetic greywater. The integrated process with ozone backwashing could produce 0.55 L/min of filtrate with an average of 18.42% permeability recovery, while the oxygen backwashing produced 0.47 L/min and 6.26%, respectively. And without any backwashing, the integrated process could produce 0.29 L/min. This shows that the ozone backwash process is capable of periodically recovering from membrane fouling. The resistance of the fouled membrane was approximately 34.4% for the process with ozone backwashing, whereas the resistance was restored by 10.8% for the process with oxygen backwashing. Despite the periodical ozone backwashing and chemical cleaning, irreversible fouling gradually increased approximately 3 to 4%. Approximately 97.6% and 15% turbidity and TOC were removed by ceramic membrane filtration, respectively. Therefore, the integrated process with ozonation and ceramic membrane filtration is a potential greywater treatment process.

  • This paper investigated the effect of music and science integrated activities using instruments designed to test both musical concept and science inquiry process skills of children. The subjects of this study consisted of two classes of children aged 5 at H Kindergarten in Busan city. This study involved a class of 31 children using a music and science integrated curriculum as the experimental group and another class of 32 children using a traditional music and science curriculum as the control group. The integrated activities were used 12 times over a 6-week period. A test was taken to evaluate the effects of the integrated activities on the children's understanding on seven sub-categories of musical concepts and six sub-categories of science inquiry process skills. The results were that the experimental group showed significantly higher improvements in all subcategories of musical concept and science inquiry process skills, compared to the control group. Based on these results, we concluded that these integrated activities were effective in the development of both musical concepts and the science inquiry process skills of children.

  • In this paper, an offshore process front end engineering design (FEED) method is systematically introduced and reviewed to enable efficient offshore oil and gas production plant engineering. An integrated process engineering environment is also presented for the topside systems of a liquefied natural gas floating production, storage, and offloading (LNG FPSO) unit, based on the concepts and procedures for the process FEED of general offshore production plants. Various activities of the general process FEED scheme are first summarized, and then the offshore process FEED method, which is applicable to all types of offshore oil and gas production plants, is presented. The integrated process engineering environment is presented according to the aforementioned FEED method. Finally, the offshore process FEED method is applied to the topside systems of an LNG FPSO in order to verify the validity and applicability of the FEED method.
