Integration system research and development for three-dimensional laser scanning information visualization in goaf

An integration processing system of three-dimensional laser scanning information visualization in goaf was developed. It is provided with multiple functions, such as laser scanning information management for goaf, cloud data de-noising optimization, construction, display and operation of three-dimensional model, model editing, profile generation, calculation of goaf volume and roof area, Boolean calculation among models and interaction with the third party soft ware. Concerning this system with a concise interface, plentiful data input/output interfaces, it is featured with high integration, simple and convenient operations of applications. According to practice, in addition to being well-adapted, this system is favorably reliable and stable.

The Three Levels of Education in Site Design Course of Architecture

“Professional Guiding Standards for Advanced Education Architecture in University Undergraduate Students”(2013 edition)indicates that the education system of architecture should include a section on“environment and site.”It should involve six learning components which are concepts of site and environment,site terrain classifications,environment of two tendencies,elements involved in the sites,elements of environmental impact,and site design.[1]As site design(drawing)has become a significant topic in the examination of registered architects,many domestic architecture colleges have set up site design courses as independent ones.After more than ten years of exploration and research in developing the education system of site design courses,teaching experiences and achievements have been acquired.Site design courses have been gradually integrated with general plan design,registered architect examination,and architectural programming.Teachers have specified relevant learning goals in the regular daily curriculum in addition to the basic and vocational education of architecture.In this way,the site design course would be more in line with the educational goals of architecture.This paper aims to analyze the education of site design courses in hope of developing the future architectural education.

Making Sense of Interdisciplinary General Education Curriculum Design: Case Study of Common Core Curriculum at the University of Hong Kong

Purpose:This research is an interview-based study that captures the academics’perspectives toward the planning and design of an interdisciplinary General Education Curriculum for undergraduate students in the Chinese context,using the Common Core Curriculum at the University of Hong Kong as a case study.Design/Approach/Methods:A total of 28 academics with various levels of academic ranking,disciplinary context,proven teaching excellence,and research productivities were individually invited for and consented to a semi-structured and face-to-face interview.Findings:This article suggests four fundamental and interrelated dimensions for consideration when structuring an interdisciplinary General Education Curriculum,namely,how to design,what is worth learning,how to learn and teach,and how to know students have learned.It is suggested that the ideal curriculum should remain coherent and coordinated,broad and balanced,as well as open and flexible,ensuring the capture of knowledge,skills,and attitudes,with the facilitation of active,authentic,and contextualized pedagogies and assessments.Originality/Value:This article has the potential of providing insight for policymakers and educators around the world to better structure an interdisciplinary General Education Curriculum by creating an overall springboard for future discussion.They can also integrate these evidence-based elements and strategies into their everyday practices.

Research on an Integrated Modeling Method of Virtual Ship Assembly

A new method of virtual ship assembly modeling which integrates ship three-dimensional design and ship construction planning was described in this paper. A workflow model of simulation modeling based on the virtual ship assembly process was also established; furthermore, a method of information transformation between the ship three-dimensional design and ship construction plan was formulated. To meet the requirements of information sharing between different systems in the ship virtual assembly, a simulation database was created by using the software engineering design method and the relational data model. With the application of this database, the information of ship three-dimensional design, construction planning, and virtual assembly can be integrated into one system. Subsequently, this new method was applied as a tool to simulate the virtual assembly of a ship, and the results guarantee its rationality and reliability.

Computer-assisted preoperative planning for proximal humeral fractures by minimally invasive plate osteosynthesis

Background Accurate and precise preoperative planning can provide information instrumental for performing less invasive articular fracture surgery. The purpose of this study was to determine that computer-assisted preoperative planning （CAPP） has the potential to improve efficiency and time in the operating room. Methods Sixty-four patients with proximal humeral fractures were treated using locking plates by minimally invasive plate osteosynthesis （MIPO） with CAPP. The time needed for virtual segmentation, reduction, and fixation of the fracture fragments were recorded. Intra and interobserver reliabilities were analyzed using the intraclass correlation coefficient. The clinical function was analyzed using Constant Score and radiology. Results The mean total time required for CAPP of two-part, three-part, and four-part proximal humeral fractures were （13.63±1.38） minutes, （23.14±2.18） minutes, and （39.61±3.01） minutes, respectively. The intra and interobserver reliabilities for all variables were high, ranging from 0.785 to 0.992. The mean operation time was （50.1±6.7） minutes. Fifty- two patients were followed up with an average time of 34.2 months. The mean Constant Score of the injury side was （82.5 ± 9.9）. Three of the fifty-two patients had four complications. Conclusion The application of CAPP was efficient and reliable, and provided excellent clinical and radiographic outcomes for the treatment of proximal humerus fractures by MIPO.
