This research is a survey study. And analyze the waste composition And guidelines for the use of seafood waste in the Thai seafood market Samut Sakhon Province According to the survey 96.27 percent of the waste comes from restaurants. This is because Most fresh seafood restaurants Will feed the seafood whole Therefore there is no garbage such as shrimp if it is a restaurant the customers will have left shrimps on the head. But the fresh restaurants give away the shrimp and crab so the garbage from the fresh restaurant only has fishbone which is very small. Because most customers accept the whole fish There were also some places where the vendors cut the fish and left their bones. But when analyzed by type of waste it found that shell waste was the highest. Which is up to 55.29 percent. Followed by shrimp shells fish bone and fish heads and crab shells the study found that seafood debris had material properties with low moisture content. It also contains calcium as the main component. For example shellfish contain calcium as the main component which is found in approximately 98.50 percent. Not only striped shells Fishbone shrimp and crab shells are also low humidity and high in calcium. The bizarre one was holding a sea bass head and a grouper head with a high amount of organic matter. And with low ash content food waste that should be analyzed for the possibility of recycling are striped shells cockle shells shrimp shells fishbone shells fishbone dumplings tuna and crab shells.

These research objectives are to study the basic formulas of Khoo-Tu dessert (dried rice balls made from rice and coconut) and to study the volume of pineapple cores instead of coconut in Khoo-Tu. The test of Khoo-Tu dessert basic formulas by 9 - point hedonic scale method of 50 examiner laboratory the results show acceptance rated on a moderate scale (7). After that substituting coconut with pineapple core the amount of 0 25 50 75 and 100 of the weight coconuts.It was found that at 75% of the substitution level the tasters evaluated the greatest acceptance (p> 0.05). The basic formulas had a pH of 6.24 the Pineapple core formulas 5.94 (p> 0.05). Water Activity (aw)of Khoo-Tu the basic formula was 0.85 and the pineapple core formula was 0.90 (p> 0.05). The color value of the pineapple core Khoo-Tu was L * (brightness value) (37.31) b * (yellowness value) (9.45) rather than the basic formula Khoo-Tu (p> 0.05). The nutritional value of the pineapple core Khoo-Tu was 316 Kcals protein 2.71 % fat 8.86 % ash 0.52 % carbohydrates 56.3 % dietary fiber 3.99 % insoluble fiber 3.60 % and 0.39% of water-soluble dietary fiber that was found in the pineapple core Khoo-Tu to provide lower nutritional value than basic formula Khoo-Tu. The microbiological quality of basic formula and pineapple core formula was found that the total variable count fungi and bacillus serous were less than 10 colonies / 1 g sample and staphylococcus aurias were not found in both samples. The shelf life of rice (Room temperature) found that the basic recipe was 12 days and the pineapple core recipe It has a shelf life of 6 days. At chilled temperature (4 degrees Celsius) it was found that the basic formula and pineapple core formula had a shelf life of 25 days with all microorganisms less than 1 x 104 colonies/sample 1 gram fungus less than 100 colonies /1 gram sample and All microorganisms and fungi exceeded the standard on the 28th day.

This research aimed to collect classify and process the data of Moh Phon’s diseases and herbal drugs from his medicine scriptures analyze and design the database with its user interfaces. Then the program of Moh Phon’s diseases and herbal drugs database was developed. After that the program was tried out by the sample group of 50 students from the third year of the field of English for International Communication faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. Finally the students of 15 males and 35 females answered the questionnaires of their satisfaction of using the program. The results were as follows: 1. The data of Moh Phon’s diseases and herbal drugs consisted of core information as follows: names of diseases names of herbal medicines names of herbs which were ingredients of each medicine recipe the properties of each medicine recipe and how to prevent some diseases. 2. The questionnaires analysis of students’ satisfaction of using the program of Moh Phon’s diseases and herbal drugs database revealed that the overall arithmetic mean of users’ satisfaction was 75.00. The highest scored item of 87.50 percent was “I think this program is useful”; and the lowest scored item of 66.50 percent was “I think the screen format is interesting”. Moreover there were 7 users who showed their positive opinions towards the program which was 14 percent of all the informants.

The objectives of this research are to study the rate of deterioration of tyre friction coefficient and investigate the quality of new and old tyres that are currently in use. A set of the rolling resistance testing was designed and set up to work with the single dynamometer according to speed 80 km/h tire load 4660 N and inflation pressure 30 psi. There were three tire samples new tire one year used tire and two year used tire to find the rolling resistance coefficients. The finding shows that the rolling resistance was inverse variation with tire aging. For instance the new tire (1st sample) had the highest rolling resistance on the other hand the two year used tire (3th sample) had the lowest rolling resistance. Moreover the rolling resistance coefficients were inverses variation with tire aging. Besides the one year used tire had the average of the decreasing rate of the rolling resistance coefficient at 0.03689 N/kN per a week while the two year had the average of the decreasing rate of the rolling resistance coefficient at 0.03671 N/kN per a week. Furthermore the result also revealed that the rolling resistance coefficients nonlinearly decreased comparing to the tire aging.
