This paper presents a mathematical simulation to compared to operations a small distributed photovoltaic power plant in the distribution system. Practices transmission of electric power by small distributed solar energy With the PVSyst and IEC 61724 mathematical modeling programs the main objective was to study the % performance ratio photovoltaic power plants 5.95 MWp connected in the distribution system of the Provincial Electricity Authority voltage level 22 kV. Therefore this paper is presented as a mathematical simulation compared to operations a small distributed photovoltaic power plant in a distribution system. The results of the study show that the operation of small distributed solar power plants increases the efficiency to be able to produce the maximum electricity and continuously. The system was able to produce the highest power of 8954.9 MWh/year and had an average annual efficiency ratio of 77.84% receiving the highest solar radiation intensity and the highest annual total energy output of approximately 1837 kWh/m2

The shelf-life extension of mulberry paste by using humectants to place sugar content could maintain the moisture while reducing the water activity (aw) of the product. The objectives of this research were to study on humectants replacement and the changes of the mulberry paste product quality during storage. The sugar content in the standard formula was replaced by 10% w/w glycerol and 90% w/w of maltitol and maltodextrin mixture (20:80 w/w). The final mulberry paste product consisted of mulberry maltodextrin maltitol glycerol salt and citric acid by 69.80% 21.62% 5.40% 3.01% 0.17% and 0.07% respectively. The chemical compositions: carbohydrates proteins fat ash fiber and moisture of the product were 76.92% 2.39% 0.14% 4.19% 4.30% 12.06% respectively. The total energy by calculation was 318.50 kcal/100 g. The anthocyanin content was 68.32 mg cyanidin- 3-glucoside/g. Total titratable acidity (citric acid equivalent) was 0.60%. The reducing sugar and total sugar values were 1.74% and 3.90% respectively. The consumer acceptance as evaluated by untrained panelists was in the level of moderately like (7 score). The product packed in glass bottle containers was stored at 27±2 ºC for 4 weeks. The aw was increased while the textural properties: hardness adhesiveness and chewiness were decreased. The chemical quality analysis showed significant decreases (p≤0.05) in the moisture and the anthocyanin contents. The microbial quality; total plate count and yeast and mold measurements were significantly increased (p≤0.05) however the values were within the acceptable range according to the Thai community product standard (35/2558).

The objectives of this : 1) to study the operating conditions of Thai restaurant business operators under Steve Cafe & Cuisine. 2 ) To study the internal and external factors related to the operation of Thai restaurant business operators under Steve Cafe & Cuisine. 3 ) To study strategies for adapting to new normal for survival in the operations of Thai restaurant business operators under Steve Cafe & Cuisine. 4 ) To compare strategies for adapting to a new normal for survival in the operations of Thai restaurant business operators under Steve Cafe & Cuisine classified by operating conditions and 5 ) to determine the relationship between strategies for adapting new normal for operational survival with the internal and external factors related to the business operations of Thai restaurant operators under the Steve Cafe & Cuisine. The population of 50 includes business owners executives managers supervisors restaurant employees and 350 consumers who choose to use the service of 3 branches of Thai Steve Cafe & Cuisine located in Bangkok namely Dhevet branch Rama VI branch and Phan Fa branch. The research instrument was a questionnaire. The statistics used for data analysis were frequency percentage mean standard deviation one-way ANOVA and statistical correlation coefficient. The results of the research found that 1 ) most of the respondents restaurant business located in Dhevet has been in business for 5 to 10 years. It is a large business (more than 20 tables) and the number of employees is more than 15 people. while having sales of 300000 baht per month or more. Curry is the restaurant’ s bestselling dish. The main customers of the restaurant are both Thais and foreigners. 2 ) The restaurant business pays attention to internal factors related to the overall business operation at a high level. When considering each aspect in descending order it was found that the aspect with the highest average was marketing followed by location and the least was personnel. 3 ) The restaurant business pays attention to external factors related to the overall business operation at a high level. When considering each aspect in descending order it was found that the highest mean was the legal factors followed by customers and the least was competitors. 4 ) The restaurant business focuses on the strategy of adapting to a new normal for survival in the overall operation at a high level. When considering each aspect in descending order it was found that the highest mean was the products followed by the price and the least. was process. 5 ) Restaurant businesses with different operating conditions emphasize the strategy of adapting to a new normal for survival in the operations of the Thai restaurant business under Steve Cafe & Cuisine were different in all aspects and 6 ) when considering the internal and external factors of the business over all there was a statistically significant correlation with the new normal strategy for survival of the Thai restaurant business under Steve Cafe & Cuisine at. 05 level

This research aims to study 1) personal factors affecting the performance of Thai commercial bank employees 2) motivation affecting the work performance of Thai commercial bank employees 3) self-development affecting the work performance of Thai commercial bank employees 4) the work performance of Thai commercial bank employees. The population for this research was 162093 Thai commercial bank employees. The sample size of 383 people was determined using Krejcie & Morgan. The data was collected from Google Form questionnaires. The statistics used to analyze the data were frequency percentage mean and standard deviation. The statistics used to test the research hypothesis were T-test one-way analysis of variance the pair test by the Scheffe method and single linear regression analysis statistics. The results showed that most of the samples were female employees between 21-30 years of age a bachelor’s degree single status income in the range of 15001-25000 Baht and a working period of 5-10 years. The respondents had their opinion level of motivation factors happiness factors and self-development factors affecting the work performance of Thai commercial bank employees.

Statistically significant at the 0.05 level and personal factors such as differences in the working period. Factors affecting the performance of Thai commercial bank employees at a statistically significant level of 0.05 and personal factors such as age education level income working period. When testing the hypothesis classified by aspects the efficiency of work of Thai commercial bank employees differed. Therefore the difference was tested by pair using Scheffe’s method. The results of hypothesis test 2 revealed that motivation affects the performance of Thai commercial bank employees. The correlation coefficient (R) = 0.858 adjusted R^2= 0.753 was statistically significant at the 0.05 level. The results of hypothesis test 3 revealed that self-development affects the efficiency of Thai commercial bank employees. The correlation coefficient (R) = 0.640 adjusted R^2= 0.40 was statistically significant at the 0.05 level.

The purpose of this research was to develop an application for setting up price for goods in the community. The application helps the retailer calculate and determine the product price with the minimal risk. In order to assess the satisfaction of the application the samples used in this study were 30 community retailers and goods producers. The research found that the application was in good quality. The evaluation of satisfaction with the application was averagely 4.45 which was at a very high level. The application can be actually used in authentic circumstances.
