The study on document management efficiency of support staff at an academic public institution was aimed to investigate 1) the personal characteristics of the academic support staff 2) the efficiency of document management of academic support staff and 3) to analyze the differences of the staff’s document management efficiency classified by their personal characteristics. The population used in this study was 78 technical support staff of a public educational institute. The questionnaire was applied to collect the data analyzed by the frequency percentage mean and standard deviation. The results revealed that most of the respondents were females who were 30 to 39 years old having been working at the institution for 6 – 10 years. The positions held during the investigation were less than five years. Most respondents had never been trained on document management. When considering each aspect it was found that the document reception and delivery were mostly handled while the document writing and keeping were at a high level. However recycling borrowing and destroying document were found average. The results of the comparison of efficiency differences of the document management of academic support staff classified by the personal characteristics showed that gender age educational level position duration of work in the educational institution were moderate revealing the equivalent level of the document management efficiency. The work position held uncovered moderate level of ง the document management efficiency except for the period of work position held for 11 to 15 years which was considered high. Twice or three times of the attendance on the document management training was considered highly efficient as opposed from those once or never being trained. This affects the efficiency of managing different types of documents.

The objectives of this study is to increase efficiency of steam boiler 2.5 ton per hour which used liquid petroleum gas LPG as fuel. bringing heat recovery inside boiler chimney stack to preheat feed water with technology heat Exchanger Economize. Taking the economizer with its pipe length of 1000 mm and 62 mm diameter for 64 pipe is a cross flow with staggered tube to increase water temperature before entering the boiler pass to deaerator The study is carried out to compare the differences and savings of the feed water temperature steam boiler efficiency and fuel consumption between having the economizer installed and uninstalled. reference to study The result after installed the heat exchanger economizer the feed water is passed into steam boiler deaerator higher temperature from 38.30°C to 67.20°C which leads to increase efficiency of steam boiler from 81.59 % to 85.65 % meaning that the fuel consumption of steam boiler will be reduced 4.97 %

The study aims to study the change leadership that affects the organizational culture and work efficiency of the staffs at the operational level and to study the good governance principles that affect the organizational culture and work efficiency of operational staffs at Commercial Concrete Production Business Unit. The population used in the study is 200 operating staffs at Commercial Concrete Production Business Unit using questionnaires for data collection. The data analysis is conducted using descriptive statistics and inferential statistics. The result indicates that change leadership affects organizational culture of operational staffs with statistical significance at 0.05 level. It can predict the organizational culture of operational staffs at 16.30 percent. Good governance principles affect the organizational culture of operational staffs with statistical significance at the level of 0.05. It can predict the organizational culture of operational staffs at 29.50 percent. Change leadership affects the operation efficiency of operational staffs with statistical significance at the level of 0.05. It can predict the work efficiency of operational staffs at 13.80 percent and good governance principles affect the work efficiency of operational staffs with statistical significance at the level of 0.05. It can predict the work efficiency of operational staffs at 28.70 percent.

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 purpose of this research were to 1) study the production factors and efficiency of fireproof suit; 2) analyze the three line balancing models of fireproof suit; and 3) make comparison of production efficiency for fireproof suit’s manufacturing processes. A group of representative sample for assessments is 90 dressmakers of Creative Polymers Co. Ltd. The used tool for collecting data is the data recoding form consisting of production process list data recording date processing operation and duration of processing. Accordingly put the sewing line layout and make production test with the three line balancing models of fireproof suit then record all data and entry all data to SPSS program to average statistics on percentage and standard deviation. The research showed that the improvement of the three line processing models of fireproof suit comparing to the data of the three line balancing models are identified that C model increased from traditional production system 74.05 percentage B model increased from traditional production system 57.51 percentage then A model increased from traditional production system 48.53 percentage. The result showed that the fireproof suit’s production processing of Creative Polymers Co. Ltd. ought to take the C model in order to fasten production process and augment better quality. A minimum process of producing is amount of 110 steps with less time per one unit; minimum 177.41 minutes; with 30 workers; and 27 machines. The waste product of the three line processing models: A B and C model; not over 20 percentage during 8 hours of working. It shows that the c model has the least of waste product. The over operation that product has not much wasted not include in choosing the model for improving production efficiency and C model
