The purpose of this research is to develop learning package for an operating system course on process status for undergraduate students majoring in computer engineering. The technique of creating the cartoon story for difficult content is used to compare the process status and the steps of buying meals to enhance students’ understanding of process management. The participants are divided into two groups; the control group learning with the traditional method the experiment group learning with the learning package. The research result was that the achievement of the experimental group was higher than the control group. In addition the students were interested in learning and the students’ satisfaction is at the high level.

Current energy from sun made a significant contribution in the electricity manufacturing industry in Thailand. However the potential application of solar energy are at the low level. The agency will need to make solar energy perpendicular to the sun as much as possible. Therefore the invention of the light experimental set for two-axis motion to identify the vertical axis was done to compare the value of Light Dependent Resistor to locate the origin of the light and can be applied to the real work in the future.

Replacement of fertilizer with latex sludge as nutrient sources for oil palm seedlings (3 months) was conducted in randomized complete block design (RCBD) with 3 replications. The treatments consisted of control chemical fertilizer and latex sludge 10 30 50 70 and 90 grams per kilogram soil. The result showed that applying with latex sludge 10 and 30 grams per kilogram soil increased plant nutrients such as phosphorus potassium and magnesium significantly (p <≤ 0.05). While the growth of pre-nursery oil palm including number of leaves leaf width and length stem girth and height are the same as applied with chemical fertilizer. But using latex sludge over 30 grams per kilogram soil have an effect on oil palm seedlings by reducing growth. So in conclusion Latex sludge at the rate of 10-30 grams per kilograms soil can be replaced fertilizers as nutrient sources for pre-nursery oil palm seedlings

The study of ethical behaviors through students perception in the field of business administration in Rajamangala Institute of Technology Bangkok Commercial Campus was a study to find seven ethical behaviors of the students those were : honesty discipline generosity responsibility hard-working self-reliance and gratitude. The purpose of this research was to study seven aspects of ethical behaviors through students perception and compare the ethical behaviors between sex and learning achievement. The sample of this study selected by using simple random sampling technique from students in six majors of business administration field of study. In each major -Accounting Marketing Infonnation System Management Business English and Finance -50 students was selected as sample of the study totally 300 students. A questionnaire was used in collecting data. The findings were as follow : It was found that the ethical behaviors through the students perception was totally in high level. As for each aspect it was in high level 5 ones -gratitude honesty self-reliance discipline and responsibility respectively. For the medium level there were two aspects: hard-working and enerosity. The comparison of ethical behaviors through students perception by sex found that ethical behaviors of male students were totally in the medium level and female students were in high level. When considering in each aspect ofboth sexes the highest means was in gratitude honesty was lower. The total of comparison was found statistically significant difference at the 0.5 level. It was also found that there were four differences in statistical significance at the 0.5 level -honesty discipline responsibility and self-reliance. The comparison of ethical behaviors through students perception by learning achievement found that totally ethical behaviors of students with low achievement (lower than 2.00) were in the medium level. Students with medium achievement (2.00 -2.99) and those with high achievement (3.00 -4.00) were in high level. When considering each aspect of students with low medium and high achievement the highest means was in gratitude and followed by honesty except students with low learning achievement the lower level was discipline. The result of totally comparison was different at the 0.5 statistical significance level. There were two different aspects with statistical significance at the 0.5 level in the aspect of honesty and self-reliance.

This research is Design and construction board led dot matrix was create for study about microcontroller. It apply to use in communication & information indoor type by sending messages from computer on internet network systems. This research has implemented LED dot matrix display for display message characters. The research is composed of 4 major parts: the first part is LED dot matrix display with dimension of 16x192 dots. The second part is the control circuit by using a micro-controller ARM 7 which receives the data from computer the third part by using Microsoft Visual Basic. the forth pat program remote desktop. From tests and results we have found that it can display the message characters which move from Internet System successful.
