Mathematical spatial analysis for multiple disease mapping application to hypertension and ischemic heart disease
The objectives of this research are to estimate the morbidity rates of Hypertension and Ischemic heart disease in each province of Thailand to investigate factors influencing on the morbidity rates and to construct the disease maps of those two diseases. The generalized linear mixed model (GLMM) in which the responses have a Poisson distribution and the spatial effects are a multivariate conditional autoregressive model (MCAR) are adopted. The provincial secondary data sets consisting of a number of Hypertension and Ischemic heart disease patients an average income per head and a student proportion were collected. The results show the average income per head (Relative Risk (RR) = 1.0002) and student proportion (RR = 1.0186) influence the morbidity rates of Hypertension and Ischemic heart disease. Hypertension and Ischemic maps are easy for readers to see which areas are at high risk. They are a useful tool for planning and controlling the Hypertension and Ischemic heart disease.
Graphical method and database development for computer programming to reinforced concrete slab analysis and design
This research was to apply graphical method as the input data combined with using database for developing reinforced concrete slab analysis and design. Visual Basic language was used for creating the GUI (graphic user interface) and coding and database file was used for storing data. The position of beam column and slab can define by drawing on GUI and this program will automatic translate to be the distances for using as data in process of analysis and slab design. Results from analysis and design were compared with manual calculation that they are a litter bit error because of rounding error. Moreover they can be more economically and more conveniently than results from VisStructure 4
Grounding system analysis for reduce voltage sag in distribution system
The fault in a power distribution system disturbs the power dispatch under normal conditions therefore decreases the quality of the electric power. The single line to ground fault is an asymmetric fault that may have a high percentage chance to happen. The kind of fault changes power and voltage dramatically. The size of the phase voltage decreases which affect the economic damage of the system. This paper presents an analysis of grounding systems to reduce voltage drop in a power distribution system by using the technical analysis system in case of one phase to ground fault. The objective is to minimize voltage drop for users using the simulation with single line to ground fault in distribution system voltage level at 22 kV PEA’s test system. The simulation utilizes the EMTDC-PSCAD program. The results show that the grounding method can reduce the voltage drop and reduce the damage of the economic system
A performance analysis of a sufficiency economy philosophy practice of the handicraft maker’s group in hu-rae
The research of A Performance Analysis of a Sufficiency Economy philosophy Practice of the handicraft maker’s group in Hu-Rae is an applied research that indicate a result of guideline from a Sufficiency Economic Philosophy. The purposes to analyze the before-and-after performance of marketing management with a community’s participation project regarding to a Sufficiency Economy philosophy for product development. This research focuses on the study of a performance of the handicraft maker’s group in Hu-Rae by doing in-depth interviews before and after marketing management with a community’s participation project applied with the Sufficiency Economic philosophy for product development. In doing this the following components are applied as indicators: moderation reasonableness self-immunity conditions of knowledge and morality and comprise with the marketing mix (4Ps) which are product price place promotion. The research result reveals that the performance result referring to Sufficiency Economic philosophy is in a high level and after the research project is implemented the performance result is increase for all aspects. The condition of knowledge is considered to be the highest which receives 4.30 points. A practical implication of this research will be beneficial to a management of community network.
The analysis of the relationship between securities price and the efficiency of the account receivable management, case study: the listed companies in the stock exchange of thailand, agricultural business group
The objectives of this research are to analyze the relationship between securities price and the efficiency of the account receivable management and to study the model of improving the efficiency of the account receivable management of the agricultural business group in the Stock Exchange of Thailand. The number of data which had been used in this research was 16 random companies of all 22 companies from the listed companies in the Stock Exchange of Thailand agricultural business group by using purposive sampling method. The researcher used both quantitative and descriptive analysis method by bringing the quantitative data analysis from 2006-2010 to descriptive analyzing which had compared between the selling revenue account receivable value allowance for doubtful bad debt account receivable turnover average collection period book value per share primary earnings per share and securities price. The results of analyzing are changing in the account receivable of Chiangmai Frozen Foods Pcl. Lee Pattana Pcl.; changing in the bad debt of Pak Food Pcl.; changing in the average collection period of Thai Rubber Latex Corporation (Thailand) Pcl. Pak Food Pcl.; changing in the book value per share of Pak Food Pcl. Kiang Huat Sea Gull Trading Frozen Food Asian Seafoods Pcl. Asian Seafoods Pcl.; changing in the primary earnings per share of Thai Rubber Latex Corporation (Thailand) Pcl. Thai Luxe Enterprise Pcl. Lee Pattana Pcl. and Kiang Huat Sea Gull Trading Frozen Food Asian Seafoods had related to securities price per share.
