The objective of this work was to study the adsorption efficiency of bamboo and its surface modified with manganese oxide for removal of Pb(II) ion. The adsorption of Pb(II) from aqueous solution onto bamboo (BB) and manganese oxide-modified bamboo powder (MnO-BB) was evaluated based on batch experiment. The adsorption efficiency of MnO-BB onto Pb(II) was investigated as a function of the initial pH of 6 equilibrium time of 30 min adsorbent concentration of 5 g/L and initial concentration of Pb(II) solution in the range of 50-500 mg/L. The adsorption isotherms of Langmuir Freundlich and Dubinin-Radushkevich were used to describe the equilibrium isotherm. It is observed that the data from MnO-BB adsorbents fitted well to the Langmuir isotherm. The maximum monolayer adsorption capacities of MnO-NC were estimated as 38.76 mg/g. By comparing with BB the amount of Pb(II) adsorbed onto MnO-BB was more than BB by about 40 times under the optimized adsorption condition. According to Dubinin-Radushkevich isotherm the adsorptive mechanism of Pb(II) onto MnO-BB was chemisorption. The kinetic studies of Pb(II) demonstrated that the adsorption of Pb(II) onto MnO-BB adsorbent followed a pseudo second-order model with a good correlation. The adsorption mechanism was processed via chemical ion exchange between H+ and bonded MnO groups and Pb(II) ions in solution

The purpose of this research was to study productivity rate in concrete plastering of interior brick wall by studying 2 construction projects in Bangkok. The researcher divided the methods of labor productivity into two categories: (1) direct labor production technique and (2) field rating technique. The direct labor productivity technique of project A is about 1.38 m2/person/hr. and project B is about 1.19 m2/person/hr. by field rating technique project A had 77.75 % of workers in work status project B had 73.75% of workers in work status. The error rate was 4.08 % and 4.31 % respectively at the 95% confidence level. Project A has higher productivity rate than project B because project manager A chooses ready-mixed plaster for plastering. Project B selects cement mix (silica cement) mixed with fine sand cement mixer and water which take longer to prepare than Project A resulted cost of materials increase for 28.21 %.Meanwhile the working time for wall plastering could take longer for 13.77 %. It can be concluded that the selection of material for work is another factor affecting labor productivity

The research of strategic accounting information systems of technology and targeted industry groups to Thailand 4.0 was aimed at studying 1) strategic accounting information systems of technology and targeted industry groups to Thailand 4.0 and 2) factors related to strategic accounting information systems of technology and targeted industry groups to Thailand 4.0. The questionnaires were constructed as a research tool for collecting data from 400 entrepreneurs in technology and targeted industry groups. The data was statistically analyzed by frequency distribution percentage mean standard deviation and multiple classification analysis: MCA. The research findings indicated that most entrepreneurs in the technology and targeted industry groups were in food agriculture and biotechnology. Their capital to run business at the present time was between baht 1000001-1500000. The average number of employees was 4.75. They had income of baht 5000001-7500000 per year. Most of them employed companies or organizations to develop their own accounting information systems and their practicable period was 7.61 years. The capacity accounting information systems was totally at high level ( =3.64). Also the usability of accounting information systems was totally at high level ( =3.67) whose data collection was at =4.00 data processing at =3.66 data controlling at =3.53 and information generation at =3.51 respectively. The hypothesis testing results at statistical significance of 0.05 showed that the capacity of accounting information systems was the vital factor relating to data collection data processing data controlling and information generation and the annual income of entrepreneurs in strategic accounting information systems to Thailand 4.0 was related to data collection data processing and strategic accounting information systems to Thailand 4.0.

This research aims to study perception and understanding about being a digital university and to study and analyze the factors that affect digital university. There are benefits to be given as a guideline in determining the direction of university operations in line with future change conditions. And it is a way to develop a university into a digital university. Population used in this study was 1250 people from staffs at Rajamangala University of Technology Phra Nakhon.
