Development Information System to support activities of Nang Loeng Community, Bangkok
Development Information System to support activities of Nang Loeng Community, Bangkok

The objectives of this research are to analysis design and develop the Information System to support activities of Nang Loeng Community Bangkok. Also to install test and evaluate the system. To develop the System Development Life Cycle (SDLC) method is used. To develop and implement PHP script language and MySQL database management system are used. And the system is installed on the Internet Server. To evaluate the satisfaction the 2 groups are the samples the first is the group of 19 operation users and the second is the groups of 30 general users. Convenience sampling is used for sampling method. Gathered and analyzed the data by statistical processing program for Windows software. The result of research show that the satisfaction of the first group (19 operation users) about input screen a data entry is in a good level (x=4.00). About working process and reporting of the system is in a good level (x=4.15) the satisfaction of the group is a good level (x=4.08) The satisfaction of the group (43 general users) the results appear in the same level to the satisfaction of the first group in every case (x=4.21). So the research results can be concluded that all samples are highly satisfied with this information system. And this system can be installed in real working and suit the user requirement.

Situation and Demand Regarding ICT Training of Elderly in Bangkok
Situation and Demand Regarding ICT Training of Elderly in Bangkok

This study employs a mixed method research which is a combination of quantitative and qualitative measures to investigate situation and demand in relation to Information and Communications Technology (ICT) training of the elderly in Bangkok. For quantitative method questionnaires are used to obtain information from a total of 355 senior citizens. These data are examined and evaluated by way of descriptive statistical analysis involving frequency percentage mean and standard deviation with t-test and a one-way analysis of variance (ANOVA). For qualitative method in-depth interviews of 10 coordinators of the Association for the Elderly are undertaken and a focus group of 10 representatives of the Association for the Elderly is employed. The results show that a majority of the elderly do not have a computer (56.3%) or experience of using ICT (33.8%) but indicate demand for ICT training (59.4%) with regard to reading information and news and communicating by way of the internet. In detail there is demand for free training courses dealing with computer use and the internet as well as searching queries convenience of travel to training centres and trainers who understand the capability of the elderly. Comparison by income shows that the elderly whose average monthly income is more than 30000 bahts pay more attention to training courses and services travel convenience and trainers than do those on lower income. Furthermore the demand for training is higher for the elderly who have ICT experiences than for those with no experience. In conclusion the findings of this study suggest that policymakers should provide the elderly in Bangkok with public-access computers free internet connection availability of reduced-price computers and financial support for ICT training courses.

Problems and Barriers for cooperative Education Student Trainee Recruitment according to the Work Place’s concept : A Case Study of Undergraduates of Business Administration Faculty : A Case Study of Undergraduates of Business Administration Faculty, Rajamangala University of Technology Phra Nakhon
Problems and Barriers for cooperative Education Student Trainee Recruitment according to the Work Place’s concept : A Case Study of Undergraduates of Business Administration Faculty : A Case Study of Undergraduates of Business Administration Faculty, Rajamangala University of Technology Phra Nakhon

This research is to study the problems and barriers for cooperative education student trainee recruitment according to the work place’s concept the aspects of training management training format training students’ qualifications and training students’ knowledge. The population are owners of various workplaces who accept 180 fourth year undergraduate students in training. Questionnaires are used to collect data statistically analyzed by Percentage Mean and Standard Deviation. The findings of the research reveals problems and obstacles as follow : 1. For the training management aspect the workplaces are not able to cooperate with the university to set aims and prepare the students before training the workplaces do not recognize purposes of the university’s training course the suitable positions for the students are not provided by the workplaces. 2. For the training students’ qualifications the students are unlikely to make decision in their performances’ problem solving no self-confidence and carefulness in their performances. 3. For the training students’ knowledge the students are unable to analyze and plan their performances; they have not a good command of both written and spoken English and Thai. In addition they lack of vocational skills.

Abrasive wear behavior of diffusion layer by Pack Cementation on low carbon steel
Abrasive wear behavior of diffusion layer by Pack Cementation on low carbon steel

This research aims to study abrasive wear behavior of diffusion layer by pack cementation on low carbon steel. Chemical compositions of pack cementation include 42wt% Ferro-silicon 17wt% sand 3wt% NH4Cl 12wt% clay and 26wt% Liquid glass. The specimens were heated in the induction furnace at 950?C and 1050?C for 20 and 30 hrs. Microstructure of diffusion layer was analyzed with Optical and Scanning Electron Microscopy and hardness of diffusion layer was tested with a Vickers indenter. The abrasive wear tests were carried out in a Dry Sand Rubber Wheel abrasion machine according to ASTM G65 standard. Results showed that the heating temperature of 1050?C for 20 hrs. yielded high hardness level of approximately 394.26HV0.02 and low average wear resistance of 0.0751g. The worn surface exhibited deep grooves. On the other hand the heated treatment for 30 hrs. yielded the highest diffusion layer of approximately 910?m and the microstructure of Fe5Si3 ?1 and ?Fe.

Two-dimensional transient model for prediction of temperature profile at heat pipe wall
Two-dimensional transient model for prediction of temperature profile at heat pipe wall

Distribution trend of transient temperature profile of copper heat pipe from the start-up of outer wall temperature of evaporator section until the temperature was steady was studied. A two-dimensional model used numerical solution which based on finite difference method. The transient temperature distributions measured in all 3 heat pipe sections were compared with results from the numerical solution of the two-dimensional model that utilized the concept of temperature distribution in the pipe wall during transient operation. Results showed that the experimental trend and the theoretically predicted temperature profiles were similar. Moreover there was good agreement when compared with the numerical simulation of Mistry et al. (2010). Therefore the numerical-validated heat pipe temperature distributions were successfully simulated in a two-dimensional model.
