The objectives of this research were to study chemical composition of crude extract from Naringi crenulata (Roxb.) Nicolson and Coix lacryma-jobi Linn to determine the appropriate ratio of crude extract between Naringi crenulata (Roxb.) Nicolson and Coix lacryma-jobi Linn to develop a facial washing gel derived from crude extract from Naringi crenulata (Roxb.) Nicolson and Coix lacryma-jobi Linn. The results showed that the crude extracts from Naringi crenulata (Roxb.) Nicolson and Coix lacryma-jobi Linn had the total phenolic at 45.21 and 38.24 g/ml respectively. Whereas the total tannin from Naringi crenulata (Roxb.) Nicolson and Coix lacryma-jobi Linn was 33.76 and 22.08 g/ml respectively. The steroids-terpene flavonoid and alkaloid were found in the crude extract of Naringi crenulata (Roxb.)Nicolson. The Steroids-terpene and flavonoid was found in crude extract of Coix lacryma-jobi Linn. IC50 of the tyrosinase inhibition was 0.28 mg/ml. The ratio of the crude extract could inhibition the enzyme tyrosinase was 1:1 with the IC500.18 mg/ml. The facial washing gel had red–brown colour with slightly smell from the extract with stable bubble. In addition the pH of the product was 6.7

The purposes of this research were 1) Study behavior and demand of consumers for handicraft product from palm leaf. 2) Design and development handicraft product from palm Leaf. 3) Study of consumer satisfaction for handicraft product from palm Leaf. The results found that. the community of housewife at Tambon Takaok choose artificial flowers and bag. Demand of the buyer in Tall vase flower arrangements Image of Buddha decorate with flower spherical vase flower arrangements and corsages handbag purse and cosmetic bag. Pass the tested to Thai Community Product Standard.The result of customer satisfaction showed that the average highest satisfaction product was spherical vase flower arrangements corsages and tall vase flower arrangements. The average high satisfaction product was Image of Buddha decorate with flowercosmetic bagpurse and handbag .

During the daytime solar cells can be used in terms of meteorology because the variations of the current obtained from solar cells are associated with changes in daily climate. The case study of the comparison between the surface temperature and the different current (Ipv_d) obtained from the solar cells in the periods of November 2011 to February 2012 which known as the winter period of Thailand had been conducted. The result showed that it was possible to observe the decreased surface temperature at the time that the increased Ipv_d was more than 6000 mA. Vice versa the decreased surface temperature would not be observed when the Ipv_d was below 6000 mA. The decreased surface temperature may reflect the influence of the traveling high pressure area moving to cover and collide with the steady-low pressure area at the study area. The result of the collision caused extensive cloud cover resulting in increasing Ipv_d.

The objectives of this research were 1) to study problem of joint learning for children with learning disabilities and 2) to develop a joint learning management model for children with learning disabilities. This study used a sample group of 74 school administrators 87 teachers and 46 supervisors. Data were collected by questionnaire and analyzed for t-test mean and standard deviation (S.D.). Results revealed that firstly concerning the joint learning management model for children with learning disabilities overall operational condition and need for development were in high level. Considered by item it was found that financial management and procurement were in high level. Secondly comparison of operational condition and need for development in joint learning management for children with learning disabilities between overall results and itemized results was significantly different at the level of .01. Thirdly the joint learning management model for children with learning disabilities consisted of 7 areas: 1) academic administration; 2) management process; 3) Knowledge management; 4) organizational structure and personnel; 5) human resource management; 6) general administration; and 7) financial and procurement management.

The objective of this research were to focus the antioxidant activity and separated the chemical compound of crude extract from Feronia limonia Swingle branch. After that the optimum antioxidant of crude extract was used to prepare the antioxidant lotion. The result showed that crude extract had total phenolic and total tannin contents 41.99 and 52.35 g/ml ; respectively and also had antioxidant activity (IC50) 12.55 ?g/ml Whereas BHT and BHA had IC50 8.96 and 9.61 ?g/ml. The separation of crude extract can be separated into four groups (F1 F2 F3 F4) and the results showed that F2 has the strongest activity against the others with IC50 = 9.53 ?g/ml. Then F2 was analyzed with GC-MS and found that the structure were Hexadecanoic acid Ethyl ester Trimethylsilyl ester and Dioctyl ester. The lotion was odorless white color with no phase separation with pH 8.0
