The objective of this survey research was to study the opinion of people in Samutsakhon Municipality Samutsakhon province concerning the construction of on-ground pipe-water production system. The results of this survey research were as follows : the opinion and requirement of people in Samutsakhon concerning the construction of on-ground pipe-water production system were at high level. The perception of problems concerning the construction of pipe-water production system was not relative to the opinion of people in However the perception of information in constructing pipe-water production system and the participatory responsibilities in service of pipe-water production system were positively and significantly relative to the opinion of people at the level of .05

In this paper we have analyzed the performance of combining security system (SSL Protocol) with current TCP/IP module by porting security shareware into the EDC (Electronic Data Capture) devices. Finally in order to understand the impact on the EDC’s performance we test the throughput of the EDC before and after applying security with various encryption algorithms.

Now a day the mostly air condition are use vapor compression refrigeration system in which R-22 refrigerant is used as a working substance. From the results of study it found that the quantity of water vapor or moisture in the air is condensed with in the fan coil unit while through out the evaporator. The fluid after condense is called condensed water. By this process the quantity of condensed water is increases when the air condition is used in the long time. To increase the utility the condensed water is recovered for the heart reduction in the finned-tube condenser. The experiment is consist of two conditions by using the air and condensed water to heart reduction. But in case of condensed water the pressure operation is controlled at 280 and 260 Psig respectively. The results of experiment shown the refrigeration effect coefficient of performance (C.O.P) and energy efficiency ratio (EER) is 39675 Btu/hr 3.01 and 10.3 Btu/hr.Watt respectively with the air is used. At the pressure operation 280 Psig refrigeration effect (C.O.P) and (EER) is 44212 Btu/hr 3.38 and 11.5 Btu/hr.Watt respectively and 49856 Btu/hr 3.99 and 13.6 Btu/hr.Watt at pressure operation 260 Psig. Furthermore the capacity of condenser is increases to 11.43% and 25.6% and also the refrigerant efficient is increases to 12.43% and 32.43% at the pressure operation 280 and 260 Psig. Thus the parameter of the energy efficiency ratio depends on the capacity of condenser working substance temperature (pressure operation) and air surrounding temperature.

Talad Noi Community is an ancient Chinese community found since the beginning of Rattanakosin. There are many important historical values in this area but also there are still many problems caused from the prosperity of the urban community leading to the process of swallowing up until disappeared from the development of big cities like all old towns. Therefore these solutions can to be promoted by utilizing the applications to promote minor market community activities. To the development of applications it can be concluded that the overall system users both general users and administrators are at a very good level. In terms of the ability of various systems administrators are satisfied with the user manual of the system that is clear and easy to understand as much as possible. As for working according to various functions in the system administrators are satisfied with setting the password using check and the satisfaction system of users. In addition general users satisfy with the overall systems as their convenience and speed.

The development of the application to support tourism in Samut Songkhram province aims to develop accommodation search applications. Hotels attractions OTOP products to promote the distribution of OTOP products in tourist attractions to assess satisfaction with developed applications using AppSheet Google Sheet Google Map and other open-source software to develop and surveys to collect data assess satisfaction with built applications. Perform statistical data analysis Percentage average standard deviation The results showed that the application to support tourism in Samut Songkhram province Help promote comprehensive tourism in Samut Songkhram Province Enhances the distribution channels of OTOP products in tourist attractions. The results of the satisfaction assessment from 50 users in the sample system showed that users were satisfied with the application to support tourism in Samut Songkhram province with an average of 4.41 standard deviations of 0.06. Can be used.
