This paper describes and demonstrates how "ME-105 Computer Aided Engineering Graphics" course was offered to non-mechanical engineering students at Middle East Technical University (METU) using Web-based materials.
Introduction Each year approximately 210 mechanical engineering students learn CAD system efficiently together with the basic engineering concepts in ME113-114 Computer Aided Engineering Drawing I and II courses.
Teaching the non-mechanical engineering students at the same level of quality that of mechanical engineering students using the traditional method was impossible.
Course materials are segmented into weekly modules and released on a weekly basis (Fig. 1).
Therefore, the course information and materials given above are provided online via the Web browser.

Research on Multi-objective Decision-making of Materials Selection for Green Manufacturing Xi Junjie1, a, Liu Hongyu2, b and Liu Junqing3, c 1School of Mechatronics Engineering, Zhengzhou Institute of Aeronautical Industry Management, Zhengzhou, 450015, China 2School of Mechanical Engineering and Automation, University of Science and Technology Liaoning, Anshan, 114051, China 3Department of Automatic Control, Shenyang Institute of Engineering, Liaoning, Shenyang, 110136, China ajunjiexi@163.com, blhy_13@126.com, cjunqing_liu@126.com Keywords: green manufacturing; green materials; materials selection; environmental harmony; multi-objective decision-making; constraint conditions Abstract.
Materials selection for green manufacturing is a complicated system engineering.
Engineering material mainly contains metal material, inorganic non-metallic material, polymer material and so on.
Engineering material manufacture industry mainly contains metallurgy, chemistry and chemical engineering industry which all result in environmental pollution.
For scarce material sources, their substitute materials and new materials including engineering plastic, structural ceramics, and composite material should be chosen.

Based on the biological purification technology combined with the engineering measures, the enhanced nitrogen purification biological experiment is implemented in Wenyu River in Beijing.
The walls of eco-groove are covered with aluminum foil to prevent light in, and to simulate the working environment of the river ecological engineering.
The plants themselves can absorb some nitrogen and phosphorus nutrients through root system which is the effective way for ecological engineering to supplement carbon sources.
Through the comparison of adscititious biological materials and the blank group, we find that the denitrification effects are not significant.

The production of layers and coatings with complex microstructure and application requirements (related to coated materials, the geometry of the engineered elements, economic viability) create a need for advanced technological and organizational solutions.
The development of surface engineering resulted in the emergence of many new coating materials (e.g. compound, multilayers, and gradient coatings) as well as hybrid layers produced by duplex methods.
It is these new materials that have allowed the gradual expansion of the surface engineering field in the industry, for example, in highly efficient machining or plastic forming.
Characteristics of innovative solutions in surface engineering area In the process of generating, creating, and implementation in the economy, the innovative solutions in materials and surface engineering technology must be carried out in cooperation with the industry.
The process of generating, creating, and implementing innovative solutions for the economy in materials and technology within surface engineering requires continuous, broad market analysis through cooperation with economic entities as potential recipients of emerging technical and technological solutions.

The rapid development of modern technology needs the support of many new materials.
Since the third wave of science and technology swept the world, new materials, together with information energy, have been called the three-generation pillars of modern science and technology.
Material science has developed into an interdisciplinary and comprehensive discipline.
The articles collected from ICKEM 2022 introduce readers to the research results and engineering solutions in the area of materials for application in machinery, environmental engineering, biomedicine, electronics and electrical engineering.

The Engineering Pricing and Project Bidding Management Liping Qin1,a, Zhiqiang Zhang1 1Hubei Polytechnic University, Huangshi,Hubei, 435003 aqinlp_hbpu@163.com Key words: Engineering Pricing; Project Bidding; Management Abstract: Our current engineering pricing mode and management method still is not standard, the coexistence about all kinds of the engineering pricing method, especially the large problem of pricing method of private project.
The engineering cost accounting subject setting of Hongkong is in project start-up costs which include: insurance, temporary facilities construction costs, utilities and other eighteen kinds ; the project costs included labor costs, machinery costs, material costs, management fees, profit, engineering project risk premium and so on.
In the engineering cost accounting subjects of America ,the direct cost of project included four parts what are the labor costs, machinery costs, the cost of materials and engineering subcontracting fees; the indirect cost of project included site management fee, general management fee, the site supervision fees, management fees and temporary facilities fee, as well as the conventional site management fees of two level subjects; in the engineering of gross margin include engineering tax and net profit; in addition, there is an unpredictable fee as project risk management reserve cost.
In the engineering cost accounting subjects of Japan, the direct cost of project including subdivisional labor costs, machinery costs, material fee; Comprehensive construction fees are temporary material fees, utilities, transportation, post and Telecommunications fee; site funds include insurance, office expenses, compensation fees; integrated management fees have headquarters management fees, taxes and profits.
From these three different kinds of engineering cost, the engineering cost of national or regional structure are different and the engineering cost with our existing basic are similar, just division of project cost categories are different.
