Currently car theft in Thailand is one problem that affects the economy and involves transnational criminals although there are many anti-theft devices available on the market. These mechanisms include gear locking devices steering wheel locking devices clutch/brake locking systems TDS systems voice transmissions wireless door-lock remote control system and GPS car tracking devices. Of the mentioned devices the GPS tracking devices are interesting as they use the principle of connecting to the cell phone system to send on-demand the GPS location of the car to the owners phone in the case that the vehicle is stolen. However these devices are not popular in the marketplace because the service fees are quite expensive. Also the function of these devices is to send the vehicles location to the verified car owner so the protection function is activated after the vehicle is stolen and the owner is only then aware that the car has been stolen. This is different from the devices that researchers have developed. The researchers equipment for when someone tries to steal a vehicle is the system will detect the movement inside the car and send the GPS location to the car owner instantaneously. Additionally the device was developed by using LoRa technology to transmit the data giving a lower operating cost than by using a GPS tracking device as sold on the market presently.

The study of the efficiency of fuel consumption by adjusting the fuel injection pressure is basically one optimization method to maximize the engine combustion. In this current study the Honda wave 110 cc. engine has been used to test in particular the fuel injection by adjusting the pressure of injector. To control the pressure of injection was made by automatic valve injectors with three different pneumatic pressure which were 2 2.5 and 3 bars respectively and the similar running distance of 5km. The results showed that at 2 bars the obtained fuel saving was 1020.68 km/L and the speed at 25.23 km/h which corresponded to the highest CO2 emissions during the engine combustion.

Results show that a sample of 40 players selected by convenient sampling method has an overall satisfaction score at high level (X̄ = 3.83). In addition 1) card game suitability 2) pleasant card appearance and 3) playing recurrence are players’ 3 most satisfied aspects at high level with average score of 3.85 3.82 and 3.77 respectively. This study also found 30 percent of respondents encountered with bullying situations in the card game before (X̄ = 3.83 SD = 0.07).

The purpose of this research was to design and carved soap products for gift and souvenirs and to study the opinions on the product design from carved soap products as gift souvenirs. The tool was questionnaire as the collect data from 7 experts and 100 samples. The data were analyzed by frequency percentage and mean in the form of tables and description as follow: 1. Most experts commented that should develop the product design from carved soap to difference from another one in the market. In addition the problem of creating product design from carved soap should be explain how to use chemicals to help maintaining. Then developmental guidelines should provide a number of useful uses and show polyester resurfacing on carved soap it is suitable because of keeping them were not broken. Moreover the polyester resin coating is too thick it was effect pattern craving more clearly Finally they chose the second sketching ideas because the product can hang on the wall and put in the table. It is quite look natural. 2. The samples opinions on the products of carved soap as a gift found that the design at the high level the average was at 4 . 1 5 . The overall aesthetic was at the highest level at 4.23 in terms of value and utility. The overall score was at 4.23.
