The purposes of this research were to study the satisfaction of the inspected towards the internal audit and to compare the inspected satisfaction in each aspect according to sex age job position and experience. The sample participated in this research consisted of 200 of unit executives faculty secretaries division heads and operating officials who dealt with the process of the internal audit. The tool used to collect data was a questionnaire; the statistics used to analyze the data were percentage Arithmetic mean standard deviation t-test one-way ANOVA and Fisher’s Least Significant Difference (LSD) was used after significant difference was found between groups.

This research considers the vehicle routing problem in a specific bakery making company where is located in Bangkok. This company has to produce and deliver the bakeries to its customers everyday. Until now this mentioned company generates the delivery’s route by using the experience taken from the company’s truck driver. The company has to daily use the route with unnecessary long distances. According to the given statement this research aims to develop algorithm to generate the delivery route for this company by using the Genetic Algorithm in order to minimize the transportation distances.

The organizational environments have been dynamically changed. Chief executive officer must turn an ailing organization around by rethinking a new mission. With global competition and trend of environmental performance improvement the green management then becomes substantially strategic orientation. The new management techniques such as Total Quality Management and Lean Management are introduced to the organization for achieving its new mission. The researchers use case studies method to describe the causal relationship between productivity derived from continuous improvement initiatives and green management by presenting four empirical cases. The results of all cases were measured by differentiation and integration criterion and then quantified by the concept of Time-Driven Activity-Based Costing. The findings of this paper are the causal inference and continuous improvement initiative procedure

This research is aimed at investigating the amount of chromium carbide (Cr23C6) in stainless steel AISI 304 by electrochemical technique testing in calculating the Pa values that corresponding to sensitization stage and the corrosion behavior. The results will carry on to developing the welding process. The specimens were produced with Shielded Metal Arc Welding method. Moreover it was bending at the angle 0 90 and 180 degree and the process finished on post-heat treatment with different cool down conditions are 800ºC annealed in air cooled 1100ºC annealed in water cooled and annealed 1100ºC in air cooled respectively. The results show that: first conditional is appeared the maximum amount of Pa value (Pa > 0.4) indicating that more precipitation of Cr23C6 in heat affected zone (HAZ) of specimen. The second conditional is not found the sensitization stage because when the specimens were annealed at high temperature the chromium carbide will break up and residual stress in HAZ will decrease. At last conditional is found the less amount of Pa value; the reason of using high temperature on annealing process will decrease chromium carbide but slowly air-induced cooling must pass the critical temperature then some Cr23C6 will appear at grain boundary and cause of high corrosion rate. Concerning to the corrosion behavior the second conditional present the lowest corrosion rate corresponding to the better-quality of passive film. Whereas the first conditional shown the highest corrosion rate and low quality of passive film. Thus 1100ºC annealed with water cooled is excellent condition for developing the welding process.

The purposes of this research were to build and develop a standardized test used to measure English abilities compliant with the curriculum of the fourth-year students of Rajamangala University of Technology Phra Nakhon. There were two groups of the students namely the first group which consisted of 57 students who took the traditional pilot paper test and the latter which consisted of 63 students taking the electronic test via the Internet. The other purposes were to find out the students/users’ attitudes and satisfaction towards the use of the electronic test and to obtain a computer program prototype for measuring English abilities. The results were as follows: 1. The item analysis of the pilot paper test revealed that there were 64 items of appropriate difficulty index and discrimination power whereas that of the electronic test revealed that only 56 items had appropriate difficulty index and discrimination power. Even though the latter test had been improved the accepted items were fewer. This led to the assumption that the characteristics of doing an electronic test affected students’ decisions and made them guess more than when they took a paper test. 2. The questionnaires analysis of students’ satisfaction of using the electronic test program to measure their English abilities revealed that the overall arithmetic mean was 75.72. The highest scored item of 87.59 percent was “I think this e-test program is useful”; and the lowest scored item of 66.21 percent was “I think the screen format is interesting”. Moreover there were 11 users who showed their positive opinions towards the e-test program which was 18.97 percent of the latter group.
