Web-based Collaboration Systems for Structural Design: A Review
Lim, Jinkang,Lee, Jaewook,Lee, Seunghye,Kim, Han Soo,Jung, Sungwon Korean Institute of Building Information Modeling 2015 KIBIM Magazine Vol.5 No.4
In a construction project, collaboration amongst the project participants is a critical factor for high-quality results and successful completion of the project. Owing to the advance of information technologies, web-based systems have become more common in the construction industry, but research and development has been made for only limited areas. For organized and systematic collaboration in various fields, collaboration systems have to be developed in a holistic manner based on diverse needs from the whole construction industry. This study aims to investigate the current status of web-based collaboration systems from structural engineers' perspectives and propose an improvement plan. For a systematic analysis of selected cases, we apply a classification of three developmental stages depending on interoperability and organizational levels: structural design and analysis, collaborative design, and integrated design management. Thereafter, the characteristics of each stage are extracted and comparatively analyzed. Lastly, three functional factors were proposed for the improvement of web-based collaboration systems for structural design.

Recently, acupuncture has demonstrated extraordinary clinical results in the treatment of several categories of health conditions worldwide. The mechanisms of action of acupuncture (including immune mechanisms) have been investigated by biomedical studies over the last few decades. The immune mechanisms of representative clinical conditions and their clinical effects were thoroughly assessed, with a comprehensive investigation into the mechanisms of action of acupuncture (including immune responses) in this study. Conditions such as stroke, migraine, depression, chronic fatigue syndrome, lower back pain, hypertension, irritable bowel syndrome, sepsis, and allergic diseases were meticulously examined. This in-depth analysis aims to ensure a foundational understanding of the immune mechanisms involved in acupuncture, thereby serving as an initial step toward integrating the impact of acupuncture on the immune system.

As buildings become larger and more complicated, construction costs have increased with a considerable effect on buildings' Life Cycle Cost (LCC). However, there has been little consideration on economic aspects in the selection of construction materials due to limited information on the materials and dependency in architects' experience and inefficiency in cost estimation, causing design changes, increase in maintenance cost, difficulty in budgeting, and decrease in building performance. To solve these problems, this study proposed a BIM-based material selection model which reflects the comprehensive economic efficiency of building materials. Our cost prediction model can estimates the material-related cost during the entire building life cycle. Furthermore, we implemented the proposed model in connection with BIM, which can analyze and compare LCC by material. Through the validation of the model, we could confirm the necessity of LCC-based material selection in comparison with the conventional cost-centered material selection.
