The purposes of this study were to 1 ) study problems of the inventory administration of the Office of the Teacher Civil Service and Educational Personnel Commission in terms of supplying controlling and exterminating the inventory and 2 ) examine solutions to problems to improve of the inventory administration of the Office of the Teacher Civil Service and Educational Personnel Commission to operate more efficiently effectively transparently and verifiably. The research population consisted of 5 0 direct staff members working in the field of office supplies in the Office of the Teacher Civil Service and Educational Personnel Commission. The instruments used for data collection were questionnaires and statistics used for data analysis included percentage mean and standard deviation. The results of the research revealed that the problem of the administration of the inventory administration of the Office of the Teacher Civil Service and Educational Personnel Commission in the overall was moderate. When considering each aspect it was found that the inventory control aspect was the most problematic for the lack of places to store deteriorated items and exterminate within a specified period of time. The solution was to create a manual and schedule to operate the inventory more effectively. Secondly there was a problem with the cost of the inventory needed by the users that was always higher than the government standard. To solve this problem a survey on the material requirements of the internal units should be conducted before ค setting a budget for the materials to meet the current market price by all parties involved in the budget plan. Finally for the extermination of the inventory the problems were related to the responsible committee who had clear knowledge of the rules and practices of their roles and duties. Training regarding in the inventory administration should be arranged for regular and continuous understanding

The objectives of this study were to calculate the probability of type I error power of a test and to compare the performance of three test statistics: Z Student’s t and Welch’s t. Including the recommending the appropriate test statistic. Classification of the population according to five distribution. The ratios of mean group 1 per group 2 were three levels. The ratios of variance group 1 per group 2 were three levels. The sample sizes of two populations were nine sizes. The significance levels that to study were 0.01 and 0.05. The data were simulated by using SAS programming with 1000 replicates. Results of the research were Z test statistic could control the probability of type I error and had higher power of a test than other test statistics but this test is necessary to know the variances of the two groups. Therefore it was appropriate to apply the other test statistics i.e. Student’s t or Welch’s t. If the variances of the two groups were equal Student’s t was a more appropriate test statistic than Welch’s t. But if the variances of the two groups were not equal Welch’s t was a more appropriate. When both sample sizes were large and the population variances were equal we could use any tests since there is no difference in the performance.

The purposes of the case study on relationship of good governance and work efficiency of operational personnel at National Food Institute were to study 1) the perception of good governance in the workplace 2) the level of perceived work performance and 3) the relationship between good governance perception in working and work performance perception of 153 operational personnel at National Food Institute. The research instrument used in the study were questionnaire yielding data processed and analyzed by statistics including frequency percentage mean (μ) and standard deviation (σ). The research revealed that 1. The level of perceived good governance in the workplace of National Food Institute personnel in the overall picture was especially high showing moral aspect responsibility aspect transparency aspect worthiness aspect engagement aspect and rule of law aspect respectively. 2. Performance perception level of National Food Institute operational personnel in the overall picture was especially high resulting in quality of work initiative or creative knowledge about the job respectively. 3. The results of hypothesis testing revealed that the level of perceived good governance was positively and highly related with the performance level of National Food Institute operational personnel in the overall (ρ = .702) statistically significant at 0.01 level. Perceived performance in each aspect was positively related to perceived overall work effectiveness revealing average relationship between worthiness aspect engagement aspect responsibility aspect transparency aspect under average relationship between moral aspect and very low relationship between rules of law aspect. The research recommends that National Food Institute should promote the recognition of good governance especially with the emphasis on the rule of law which deals with regulations orders for it is very imperative. Trainings for example should be regularly held to create the personnel’s awareness thorough understanding and true awareness toward good governance for this will positively affect the personnel’s work performance accordingly.

The current time activated Carbon spaciously have been used in the process of wastewater Treatment and Air Pollution Treatment because of it can absorb various materials such as colors smells and organic materials both in the wastewater or air pollution In this research the researcher interest to study the activated carbon from bagasse as become more quantity in the country to use for reducing the pollution of wastewater at Sugar Company and recycling the leaving materials. This study is the Experimental Research being divided into 2 kinds of charcoal: 1) synthesizing activated carbon from bagasse 2) charcoal. The three contents of waste water: 10 50 and 100 percent are used for analyzing and testing at three periods of time: 30 60 and 90 minutes. The example of the wastewater were analyzed the color and COD. The using activated carbon from the bagasse with the content of wastewater at 10% shown that it could not absorb the color differently at every periods of time the color remained lower than 5 Pt-Co and it could reduce more COD at the more periods of time. At the content of waste water 50% shown that the more using time for absorbing the color the quality of absorbing become lower (10 15 and 20 Pt-Co) but it became more reduce COD while the absorbing the color at the content of waste water 100% found that when used the more time quality of absorbing the color became lower (25 30 and 35) while the quality of reducing the COD became increase. The charcoal at the content of wastewater 10% its’ absorbing color was 5 Pt-Co at the all periods of time but the result of reducing the COD was increase: 4300 4000 and 3800 respectively. As the testing the content of waste water at 50% shown that the more using the time its’ quality of absorbing the color became lower while the quality of reducing the COD became decrease: 7330 6500 and 6030 respectively. As studying the content of waste water 100% found that the more using the time for treatment the waste water its’ quality became decrease but it could more reduced COD. The comparison between the activated carbon from bagasse and the charcoal shown that the activated carbon from bagasse can absorb the color better than the charcoal at 0.25 Pt-Co and could more reduce COD than the charcoal 43.5 % by average at the content of waste water 10%. While the waste water 50% the activated carbon from bagasse could more absorb the color than the charcoal at 55% and can more reduced the COD than the charcoal 19.34% averagely. For the content of waste water 100 % the activate carbon from bagasse could more absorb the color than the charcoal at 54.17% and reduced the COD 7.83% by averaging.

The purposes of this experimental project are learning and comparing the result of the Vetiver confine time and the health of the plants in the community waste water. The waste water of this experimental are collected from the low-cost housing project Bang-Kruay (Pha-ngung Temple) in Prai Bang sub district Bang Kruay district Nonthaburi province. The experimentation of this project was built the 2 potholes. The first pothole was set by grow up the Songkha 3 Vetiver with the floating platform and the Songkha 3 Vetiver while the second set had only the floating platform without plants as a control. However both of the potholes were control the lead time of confine the Vetiver on 7 14 and 21 days. Parameters of this project are BOD SS nitrogen and the phosphorus. The result showed that the pothole with the Songkha 3 Vetiver was effective more than the pothole that without the Vetiver. The best lead time of confine is 7 days and the performance of BOD SS nitrogen and phosphorus are 83.32 80.31 78.88 and 76.55 that calculated in percentage. Moreover during the test process the Songkha 3 Vetiver are treated and had the survival in 100% well grew up had the new spires roots and the leaves. The waste water was on clear less sediment no foul odor. The Songkha 3 Vetiver was effectively for the community waste water treatment with the floating plat form. From the result it can be treat the BOD and SS till 14 days the
