Frozen fish thawing method using an Electrostatic Technology from a High Voltage Electricity (ETHVE) is one of an alternative method. Due to this method the material has a uniform temperature and also increase the temperature of the material resulting in a short time thawing process. Therefore the objective of this research is to develop the thawing method for frozen tunas using an ETHVE compared to some water immersion method. The experiment was carried out by using frozen tunas with an initial temperature of -18 °C then thawing frozen tunas with the ETHVE until the temperature of the tunas increased to 5 °C. Then the tunas were steamed until the temperature of 60 °C compared to that water immersion method. The qualities of steamed tunas were determined by percentage of tunas meat and tunas blood. The results showed that the tunas thawing techniques using the ETHVE provided a uniform temperature of tunas meat both the surface and the center the piece of tunas. In addition this technique also provided a higher percentage of tunas meat and tunas blood and some surface area has slight burns compared to that water immersion method. The frozen tuna which was thawed by using the ETHVE method which some surface and center using temperature at 5 °C and –2 °C respectively. The tunas surface area were slightly burned the percentage of tunas meat and tonas blood were 45% and 5% respectively. During the frozen tuna thawing using the water immersion method has the surface and center temperature at 12 °C and –2 °C respectively; The tunas surface area were very burnt the percentage of tunas meat and tunas blood were 42% and 3% respectively.

This paper aim to be improvement the installation methods for Sliding Aluminium Door and Glass in order to be the good quality product by applying the motion and time study design the new model of the receiver lock set for the sliding door. The step of study process started from studied the sliding door installation processes gathering the works process and reducing unnecessary and duplicate of work process on site elimination establishing standardized time for modifying the installation process. From the result before applied new method we founded that the installation process before installation process improvement we were spent the time of installation process at 45.38 minute per set and after we used the new method we founded that the installation process time was 35.36 minute per set it can be decreased the installation time was 10.02 minute and the efficiency of work process operation was increased 22.08 percent and the line balancing performance before improvement was 56.73 percent and after improvement was 88.40 percent and the line balancing performance was increased 31.67 percent. Unless there are the improvement installation methods it makes the company in case study will be do the work to be delay and cannot be hand over the works just in time by the schedule planning.

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

The purpose of this study is to design and develop a house from used containers for the victims. A providing residence is one of the most important requisite for the victims. In this study the unused shipping containers were modified and used as a house for the victims. A container house provided a common space and a share area for the victims to conversedshare the informations and to support each other which is the main purpose. This study decided the containers size 2.50/12/2.50 A container allocated the area into 4 main parts. The first part is for livingthe second part is the bathroomsthe third part is the stair and the forth part is the base. From the study the concluded of the design is to arrange the containers in to 4 orientations by located the containers along side the North and South. The purpose is to gain the fresh air and shelter from the glaring sun. And also the reason of reduce the energy in the residence. The useful purpose to put the 3 containers stack isit easy to install and remove. Therefore the 4 orientations are also provide the share area for the victims and separate the other part of areas clearly.

The purpose of this research was to design and develop an internet management system using radius protocol for a school. The system was developed by PHP language MySQL database and radius protocol. It allowed an administrator to grant users permission to access the internet manage their accounts check their status and record their usage history in files in addition to teachers being able to limit the use of the internet in their classrooms. The system evaluation process was divided into two parts. First the efficiency of the system was evaluated by the administrator and it was found that the system can work as required. Second the system performance was evaluated in terms of network security functional requirement and processing speed by the completion of a questionnaire by five experts. User-friendliness was evaluated by the completion of a questionnaire by 115 teachers and students. Results showed that the average efficiency was 4.22 with a standard deviation of 0.07. It can be concluded that the effectiveness of the developed system was at a high level and its application was beneficial for other organizations
