The hybrid materials of lead sulfide with montmorillonite were synthesized by a solid-solid reaction between lead-exchanged montmorillonite and sodium sulfide at ambient condition. The hybrids were characterized by powder X-ray diffraction (XRD) thermogravimetric-differential thermal analysis (TG-DTA).The basal spacing of heat-treated lead sulfide-montmorillonite-sodium sulfide (200oC) was 1.20 nm. The formation of lead sulfide in the hybrid confirmed by the non-resolved absorption band and absorption onset at 328 and 508 nm respectively for heat-treated lead sulfide-montmorillonite-sodium sulfide. The dramatic blue-shifted in the absorption onset relative to that of bulk was observed.The heat treated lead sulfide-montmorillonite-sodium sulfide showed an emission peak at 367 nm. The removal of adsorbed water resulted in the increasing intensity of the hybrid.

The purposes of the research were to 1) study the 21st century skills of English for International Communication graduates desired by employers and 2) compare the employers’ requirements to skills of English for International Communication graduates categorized by the individual factors. The sample were 55 employers participating in the cooperative education project in the academic year 2017. The research tools were questionnaires and interviews. The statistical data analysis was performed by frequency percentage mean standard deviation and F distribution and the interview data analysis was performed by frequency and content analysis. It was found that the overall requirement of the employers for the 21st century skills of the graduates was at the high level (χ = 4.43 S.D = .35). As for each attribute the highest level was enthusiasm (χ = 4.63 S.D = .45) followed by collaboration (χ = 4.58 S.D = .46) and thinking skills (χ = 4.54 S.D = .47) respectively. The lowest level was the inquiry skills (χ = 4.07 S.D = .59). The result of the research hypothesis revealed that there is no significant difference between the employers with different employment sectors and working status and the requirement of the graduates’ attributes.

This research is to study in heat transfer of hot water tank from an air conditioner which is a cylinder type and has a hot water pipe around the tank. It is used for finding a position and a pattern of distribution of the hot water pipe around the tank in the highest heat transfer condition. The study uses the cylinder of hot water tank filled 45 liters of 25 oC water. An experiment separates in 3 positions of pipe wrapping which are the bottom the center and the top of the tank. Then 80 oC of hot water run thought the hot water pipe which is wrapped around the tank for 120 minutes. The result of the experiment shows that tubing position that causes the highest heat transfer is at the bottom of tank. Pipe wrapping at the bottom of the tank has the heat transfer higher than the top of the tank at 30%. Furthermore this experiment studies in spacing of hot water pipe. There are 3 types for testing which are spacing hot water pipe as one time two times and three times of diameter of pipe. The result illustrates that spacing the hot water pipe can significantly increase the heat transfer. The heat transfer of spacing the hot water pipe in three times of diameter of pipe is higher 5.8 % than spacing in one times. In addition this research is to study in the effect of turbulent flow on the heat transfer by installing agitator in order to stir water in the tank. The result is that water stirring in the tank for increasing the heat transfer is not effective for investment because the energy using for stirring is higher than the enhanced heat transfer

The objective of this research were 1) Determination of anthocyanin in riceberry rice bran has been 1195.60 mg/L 2) To investigate the suitable amount of riceberry rice bran added into bread. Sensory evaluation revealed that the bread added 10% riceberry rice bran was similar to the bread added 30% riceberry rice bran they received the highest likability scores in terms of in the appearance color odor and taste. However their softness and overall preferences were significantly different (p<0.05). Water activity (aw) of bread added riceberry rice bran at various concentrations 10 20 and 40% were not significantly different (p>0.05) but it sighificantly decreased in bread added 30% riceberry rice bran. For texture analysis the handness of bread added 10-30% riceberry rice bran were not significance increased however the hardness of bread with 40% riceberry rice bran was significantly higher then the bread with the addition of 10%. The color of bread addition with four levels of riceberry rice bran were significantly different (p<0.05). Riceberry rice bran added into the bread reduced the brightness value reduce obesity in bread that has been recognized as having a strong flavor. The bread added 30% riceberry rice bran has been accepted dark purple fragrant rice bran. The outer skin of the bread is slightly dry and sweet taste 3) The shelf life of riceberry rice bran in bread can be stored for 3 days.

The study on relationship between lifestyle patterns and event marketing models of the elderly’s activity in Bangkok was aimed to explore the lifestyle patterns of the elderly marketing model of the elderly and the relationship between the lifestyle and the marketing model of the elderly’ activity in Bangkok Metropolis. The statistics used in the data analysis were descriptive statistics including mean percentage and Standard deviation Inferential statistics and multiple regression analysis. The research tool used to collect data was a questionnaire applied on a group of sample consisting of 200 people selected through non - probability sampling in Lak Si Thung Song Hong District Bangkok. Results of the study regarding personal factors of the elderly revealed that most of them were married males aged 60-70 years old without bachelors degrees earning average monthly income 5000-10000 baht mainly from their work savings and currently unemployed. The results of the study of the elderly’s lifestyles of the sample group showed that they mostly participated in social activities exercises hobbies and tourism activities respectively. The results of the event marketing model of the elderly also revealed that the sample needed marketing mix and most activities were to be more personal. Moreover the promotion should be made on the location marketing process cost and activities respectively. The hypothesis testing revealed that the lifestyles social activities and tourism activities were related to the event marketing of the elderly in Bangkok.
