Gac fruit healthy fruit contains many antioxidants such as beta-carotene lycopene. Traditional process by boil reduces antioxidants. The purpose of this study is to process gac juice mixed passion fruit juice by microwave. The optimum formulation from consumer tests were done with 50 juice preferred consumer show that the average like is 3.90 point (5 point). The study used the 3X2 factorial in CRD with 600 700 and 800 watts and at 45 and 55 sec. Analyzed color amount of beta-carotene lycopene pH and microorganisms showed that 700 watts at 45 sec. gave the highest level of beta-carotene contents at 38.11 ?g/g. The comparison between the gac juice mixed passion fruit juice through boiled process and the gac juice mixed passion fruit juice through microwave process was investigated. The content of beta-carotene and lycopene of juice through microwave process was than 2.43 and 1.59 times respectively.

The Factors that Effects on Household Saving Behaviour in Koh Peach Community Trang Province This study investigates effects on household saving behaviour in Koh Paech Community Trang Province. The objectives are (1) to examine the household saving behaviour (2) to analyse various factors affecting the household saving behaviour and (3) to compare household saving behaviour between general household and those which are members of the Saving Group for Production. For primary data questionnaires are employed to obtain information from a total 326 households interviewed in July 2012. These data are examined and evaluated by way of simple statistical analysis with multiple regression used to investigate the relationship between household saving and factors determining it such as the household leader’s age income expenditure and level of education. The study includes consideration of the boosting household consumption policies of the Thai government. Results of this paper indicate that most household leaders are male (70.9%) and half of them are over the age of 50 years. The majority are agriculturists (57%) and most have an elementary education (58.3%). Average number of dependents is two and the average income of households interviewed is 352904 baht/year. Average household expenditure is 186151 baht/year average assets are 2681596 baht/year average debt is 311809 baht and average household saving is 91008 baht/year. Multiple regression analysis reveals that income (0.78) and assets (0.18) both have highly significant positive relationships with household saving while for expenditure (-0.36) there is a highly significant negative relationship. An unexpected finding of no effect from interest rates on household saving may be due to a preference for convenience over returns from saving. In comparing saving behaviour the result show that households which are members of the Saving Group for Production have an average saving of 80342 baht/year. They mostly save money before spending and usually have monthly security deposits. For general households the average saving is 96274 baht/year. They mostly spend rather than save money and have infrequent security deposits.

The objectives of this research were: 1) to study psycho-social factors related to effective teaching behavior of the lectures at Faculty of Business Administration Rajamangala university of Technology Bangkok metropolitan 2) to study social characteristics and psychological characteristics that could predict effective teaching behavior of the lectures in overall and small groups at Faculty of Business Administration Rajamangala university of Technology Bangkok metropolitan 3) to study the interaction between social characteristics and psychological characteristics affecting to effective teaching behavior of the lectures at Faculty of Business Administration Rajamangala university of Technology Bangkok metropolitan. The sample used in this study consisted of 252 lectures at Faculty of Business Administration Rajamangala university of Technology Bangkok metropolitan. There were three independent variables. One was social support and the other two were innovation acceptance and attitude towards effective teaching behavior. The dependent variable was effective teaching behavior. Statistical analysis stepwise multiple regressions Two –Way ANOVA were applied to analyze lecturers in both overall and small groups according to their biosocial factors. The results of the study are as follows. 1. Three major variables to predict the lecturers’ effective teaching behavior are variables from social characteristics and psychological characteristics. In the overall group the percentage of the predictability score is 54.40. In smaller groups the percentage of the predictability score ranges from 44.60 to 62.90. The highest score is predicted by attitude towards effective teaching innovation acceptance and social support in Rajamangala university of Technology Ratanakosin. 2. The analysis from Two –Way ANOVA shows that the lecturers who highly accepted innovation and received high social support showed highly effective teaching. However the factors of innovation acceptance as well as social support had no interaction with the lecturers’ effective teaching behavior. When looking into each independent variable it was found that the score of effective teaching behavior varied according to the innovation acceptance in overall group and smaller groups which were classified into groups of male lecturers female lecturers inexperienced lecturers experienced lecturers higher-than-bachelors degree lecturers single lecturers married lecturers and lecturers from four centers of Rajamangala university of Technology. It was also found that the score of social support varied in both overall group and smaller groups of male lecturers female lecturers younger lecturers senior lecturers experienced lecturers higher-than-bachelors degree lecturers and married lecturers.

The purpose of this research is to study the effect of a safety system provided for external wall plastering activity on productivity by studying a construction of commercial buildings. The safety system composed of (1) stable scaffolding system (2) providing clean and not slip walkways on the scaffold (3) installation of handrails not less than 0.90 meters in height along sides of the scaffold (4) installing safety nets around outside perimeters of the scaffolding (5) indicating working area (6) installing stairs (7) providing protection for people who works below (8) providing tools and equipments for transporting material which are safe and ready for using and (9) providing personal protective equipment for workers. Cost of the safety system is 79665 baht for a wall area of 1510 m2 or approximately 53 baht/m2. The prevention cost is quite high because it is an initial investment cost. However contractors could repeat theirs used on future projects. Productivity rates for prior and after the used of safety system are 1.16 and 1.13 m2/person/hr respectively. The productivity declines for approximately 3%. In addition our study found an impact of predecessor activity which is a brick laying activity. If brick walls are not well aligned and plumbed the working time for wall plastering could take longer for 8%. Meanwhile the wall plastering productivity could decrease for 11% and labor cost could increase for 12%.
