Stones are major materials for various civil engineering works and architectural construction areas and various kinds of stones are being used in construction sites and those areas are also very diverse. Even though the size of domestic stone market size is currently increasing, production volume cannot meet the demand because the production method is still highly dependent on manual work. In addition, as China is rising as the center of world stone market which emphasized the strong price competitiveness, imports from China are currently increasing because China is gradually securing the quality competitiveness as well. This seems because the quality of Chinese stones does not fall behind than the quality of domestic stones and in order to recover this situation, it is considered important to maximize the productivity of domestic stone working companies through the automation of production environment and to secure the price competitiveness through quality equalization to deal with low labor costs which China is emphasizing as their strength. Based on these reasons, this development was conducted and tried to secure the competitiveness of stone working by developing automatic control technology and stone working technology using air pressure and PLC, preventing risk factors and environmental problems caused by manual work in stone working site, removing working risk factors through automation and reducing dust and noise. And accordingly, automatic corner stone trimming working machine for boundary stones was developed, and production environments were improved and productivity could be maximized through the automation of manpower dependent works.

Cost Of Construction

Presently, on the construction sites, because of the manual process of plastering the walls, there is large scale need of skilled labors and the higher labor costs are responsible for increasing the overall cost of construction of a building. The quality of plastering depends upon the skill of the labor in manual plastering method hence it contains irregular plastering surface which gives rise to risk and hazards to the infrastructure. The solution of the above issues is just to introduce an automatic plastering machine which automates the process so as to save the time and money and achieve better quality of paltering. The finishing of the walls obtained from automatic plaster machine is very smooth and accurate as compared to manual process. Hence the machine is time saving, money saving hence the total cost of the project reduces which ultimately increases the progress rate of our nation

Background: The patients on hemodialysis have a significantly decreased quality of life. One of many problems which reduce the quality of life and increase the mortality in these patients is osteoporosis and osteoporosis associated fractures. Objectives: To assess the bone density of those on hemodialysis by dual energy X ray absorptiometry and to examine the risk factors of bone density reduction in these patients. Patients and Method: This is a cross-sectional study, including 93 patients on chronic hemodialysis at the department of Hemodialysis at Cho Ray Hospital. Results: Mean bone densities at the region of interest (ROI) neck, trochanter, Ward triangle, intertrochanter and total neck are 0.603 ± 0.105; 0.583 ± 0.121; 0.811 ± 0.166; 0.489 ± 0.146; 0.723 ± 0.138 g/cm2 respectively. The prevalences of osteoporosis at those ROI are 39.8%, 15.1%; 28%; 38.7%; and 26.9% respectively. The prevalences of osteopenia at those ROI are 54.8%; 46.3%; 60.2%; 45.2% and 62.7% respectively. The prevalence of osteopososis in at least one ROI is 52.7% and the prevalence of osteopenia in at least one ROI is 47.3%. There are relations between the bone density at the neck and the gender of the patient and the albuminemia. Bone density at the trochanter is influenced by gender, albuminemia, calcemia and phosphoremia. Bone density at the intertrochanter is affected by the gender. Bone density at the Ward triangle is influenced by age and albuminemia. Total neck bone density is influenced by gender, albuminemia and phosphoremia. Conclusion: Osteoporosis in patients on chronic hemodialysis is an issue that requires our attention. There are many interventionable risk factors of bone density decrease in these patients. Key words: Osteoporosis, DEXA, chronic renal failure, chronic hemodialysis
