: Research on the business model of curry paste products Ban Khlong Samrong Community Enterprise Ban Phaeo District Samut Sakhon Province towards a sustainable community economy the researcher aims to study and analyze a business model for curry paste products and to develop curry paste products. to be desired and choice for consumers by qualitative research and participative action research. (Participatory Action Research: PAR) and the research was conducted in 3 steps namely 1) to study the concepts and theories of Business Model Canvas in order to formulate a business model for Nam Prik Kaeng products; 2) Analyze the data from an in-depth interview. Focus group discussion from the stakeholders and 3) Content Analysis with the Nam Prik Kaeng product business model. Ban Khlong Samrong Community Enterprise Ban Phaeo District Samut Sakhon Province and summarized the research results by descriptive analysis. Enterprise Ban Phaeo District Samut Sakhon Province towards a sustainable community economy is to enable the development of a business model of the Ban Khlong Samrong Community Enterprise Group. By applying modern management knowledge to manage community enterprises The results of this research can be used to communicate and create mutual understanding among community enterprise members. as a guideline for further development of curry paste products And the knowledge from this research can be used to train the community enterprise group to have knowledge on business management. Suggestions from this research found that Ban Khlong Samrong Community Enterprise Ban Phaeo District Samut Sakhon Province still lacks knowledge in marketing. Therefore there should be an extension in the next market research project.

Voltage drop is one of the power quality problems affecting power users. This happens due to the higher demand for electric power. Or a short circuit in the transmission system. This causes a voltage drop is one of the power quality problems affecting power users. This happens due to the higher demand for electric power. Or a short circuit in the transmission system. This results in drop in Solving of voltage drop problems in power distribution model with distributed generator were presented with MATLAB program by installing a generator in the distribution system. Therefore simulated a case study 5 case 1 simulation by not installing a generator at any bus case 2 simulation by installing a Generator at bus 1 case 3 Simulation by installing a Generator at bus 18 case 4 simulation by Generator installed at bus 33 and case 5 simulation by Generator installed at bus 13 17 21 31 to study the suitable location of generator installation to solve the problem of voltage drop.

In this work solar erythemal ultraviolet radiation (EUV) which affects human skin and skin cancer was investigated at Songkhla province (7.2°N 100.6°E). EUV was converted to UV index then the data was used for model development and forecasting of hourly UV index using Artificial Neural Network (ANN). The ANN model has one input layer two hidden layers and one output layer. This input layer consists of extraterrestrial erythemal ultraviolet radiation solar zenith angle aerosol optical depth and cloud index which affect ultraviolet radiation and the output layer is hourly UV index. The results show that hourly UV index obtained from ANN and that from the measurement are in reasonable agreement with root mean square difference of 12.8% and mean bias difference of -2.4%. For forecasting of the hourly UV index the data for 7 days earlier was used for forecasting the next UV index for one day or nine-hour (08:00 am.-16:00 pm.). Multi-layer perceptron and back propagation algorithm were used in the model forecasting. The results show that the UV index from the model forecasting is reasonable agrees with UV index from measurement with root mean square difference of 17.0% and mean bias difference of 0.3%.

The objective of this study is to obtain a model that maximize production of γ-linolenic acid (GLA) by the moss Physcomitrella patens employing response surface methodology (RSM). The RSM with a three-variables (sucrose potassium nitrate and glutamate concentrations) and five-level (-2 -1 0 1 and 2) central composite design (CCD) including 20 experimental runs was employed to optimize the medium composition. Results showed that the experimental data could be appropriately fitted into a second-order polynomial model with a coefficient of determination (R2) more than 0 .9 5 for GLA production. Analysis of variance (ANOVA) revealed that the model was highly significant (p<0.0001) and the effects of the sucrose (20-100 g/L) and glutamate (0.5-2.5 g/L) concentrations on GLA production were significant (p<0.05). The GLA production with the optimized culture medium (sucrose concentration of 62.92 g/L potassium nitrate of 0.80 g/L and glutamate concentration of 1 .4 2 g/L) by RSM increased 4.61 folds when compared with the standard BCD medium. This experimental value (16.37 mg GLA/L) fit well with the predicted values (16.20 mg GLA/L).

Research on Restaurant Demand for Seniors in Bang Sue Dusit and Phra Nakhon Districts Bangkok The objective was to study consumer behavior of the elderly. Food demand for senior citizens in Bang Sue Dusit and Phra Nakhon districts Bangkok The population used in this study were 400 elderly people in Bang Sue Dusit and Bangkok areas. The survey instrument was a questionnaire. The statistics used were frequency frequency percentage mean standard deviation. Two-group mean difference test and One-way ANOVA Analysis of Variance. The results of the study found that most of the respondents were female. Age between 60 - 69 years marital status Most of them are working as government pensioners. and earn less than 10 000 baht. An analysis of the behavior of the elderlys restaurant use revealed that the elderlys behavior of using the restaurant when they are together with their family. The type of restaurant that the elderly use the most is national restaurant. The frequency of using the restaurant for the elderly most of the time. The elderly will go to the restaurant on Saturday - Sunday. The elderly tend to use the restaurant 2-3 people at a time. Access to restaurants more than 501 baht or more. Results of the analysis of restaurant needs for the elderly. Classified by service marketing mix it was found that the elderly had demand for restaurants classified by service marketing mix. Overall its at a high level. The elderly had the highest level of need for physical characteristics followed by personnel at the high level. and the price is at a high level respectively. The results of the hypothesis testing of restaurant demand for the elderly and demographic characteristics revealed that gender age and income were different. There are different restaurant needs for seniors. Analysis of 4Ps marketing strategy the shop must focus on producing fresh clean products and the food must be beneficial to the health of the elderly. and clear beverages suitable for the elderly in choosing to order food. Location the shop must have a convenient location for the elderly marketing promotion Organize promotional activities according to various festivals to meet the needs of the elderly. and clear beverages suitable for the elderly in choosing to order food.
