Li Jiao, Soisuda Lohmood, Supaporn Khangkham — Mon, 30 Dec 2024 00:00:00 +0700

This study aims to deeply explore the management needs of the clothing laboratory of Shaanxi Institute of Fashion Engineering. To achieve this goal, we designed and implemented a questionnaire survey covering 282 students majoring in clothing and 78 teachers from the School of Fashion. After the data collection was completed, we took rigorous steps to process and analyze the data, including detailed classification of data types, scientific assessment of content consistency, and comprehensive consideration of the suitability and functional requirements of the laboratory. Furthermore, we used statistical methods, especially by calculating the mean and standard deviation, to analyze the questionnaire data in a quantitative way in order to draw accurate and objective conclusions.

The study found a total of 8 elements 1) laboratory equipment management 2) data and document management 3) laboratory open management 4) laboratory consumables management Related sub-elements 5) laboratory environment management 6) laboratory management personnel management 7) laboratory safety management and 8) laboratory management systems. After review by 6 experts, 4 items were revised.

Development of fried chili Tom Yum flavored packaging, according to packaging design standards, Case study: Fried chili establishment Samut Sakhon Province

Mon, 30 Dec 2024 00:00:00 +0700

Design packaging for fried chili, Case study of: Fried chili entrepreneurial Samut Sakhon Province. The objectives are 1) to study the packaging styles of fried chili of the establishment and 2) to design the packaging of fried chili. The researcher conducted data collection, use interviews and observations and use packaging design principles to design fried chili packaging. The research results found that the original design of the fried chili packaging of the establishment did not comply with the packaging design principles. The researchers designed two pieces of packaging, individual package and inner package, Number of models: 2 and presented them to the entrepreneurial. The entrepreneurial selected the first form of packaging.

Kwanchai Saeweenan, hathairat ketmaneechairat, Sopida Tuammee — Mon, 30 Dec 2024 00:00:00 +0700

This research aims to design and develop of a dry corn peeling machine. The tools used in the development include the machine frame, corn cob container, peeling unit, corn holder, power unit, transmission unit, and control system. The results from the performance evaluation of the dry corn peeling machine indicated that it is capable of peeling dry corn with a moisture content ranging between 20-25% at a rate of 10 cobs per minute, thereby achieving the predetermined objective.

Waste Reduction in Wooden Furniture Manufacturing to Enhance Logistics Efficiency Using Design of Experiments

Nithit Puntanagornpat, Burim Nilpan, Naphob Saisuwan — Mon, 30 Dec 2024 00:00:00 +0700

This research aims to 1) investigate the factors affecting the defect rate in wood furniture manufacturing and 2) identify methods to reduce the defect rate by improving production processes to enhance efficiency and reduce waste costs. Prior to improvement, the average defect rate was 8.37%, with an average monthly waste cost of 26,080 baht. The tools used for problem-solving included quantitative analysis through General Linear Model (GLM) and Analysis of Variance (ANOVA) to evaluate the impact of various factors, including wood type, wood thickness, and cutting speed. The analysis results indicated that all three factors significantly influenced the defect rate. The optimal conditions for minimizing waste involved a cutting speed of 75 revolutions per minute (RPM) and a wood thickness of 12 mm, suitable for both bagasse and particleboard. After implementing improvements, the average defect rate decreased to 3.52%, reducing the waste cost to 9,338 baht per month—a reduction of 16,742 baht per month, or 64.19% of the initial waste cost. These findings highlight the effectiveness of experimental design in reducing waste and significantly enhancing production process efficiency.

The Analysis Factor Effecting the User Satisfaction in Software Project using Data Mining Techniques

Pornthip Liewtrakul, Katawut Kaewbanjong, Chatchanan Iniam — Mon, 30 Dec 2024 00:00:00 +0700

This study aimed to analyze the factors affecting the satisfaction of users participating in software projects. The data was analyzed from 191 projects with 71 factors by using data mining techniques. The methodology consisted of three main steps: 1) Preparation of information, 2) Factor selection using feature selection techniques: Correlation, Chi-Square, Forward, Backward Elimination, Evolutionary, Information Gain, and Gain Ratio, and 3) Efficiency test by using Backpropagation Neural Network Model.

The results of the research were as follows: The result revealed that 33 factors from the Evolutionary technique provided the highest predictive percentage at 90.61. The result can be employed as basic information for software project implementation to satisfy users and applied as data to develop a more effective satisfaction predictive model.

An Analysis of factors impacting the export of coconuts in Thailand

hathairat ketmaneechairat, Sopida Tuammee, Chanidapa Boontia — Mon, 30 Dec 2024 00:00:00 +0700

This research aims to study and analyze the factors influencing Thailand's coconut exports, using Multiple Regression Analysis. The data used in this study is secondary data, collected on a monthly basis from January 2016 to December 2023, covering a total of 84 months. Based on the study and review of relevant literature, the researcher identified the factors influencing Thailand's coconut exports. The independent variables are coconut export price, coconut export value, rainfall, average temperature, and foreign exchange rate, while the dependent variable is the volume of Thailand's coconut exports. The research results revealed that the factors influencing Thailand's coconut exports, based on a significance level (Sig.) of less than 0.05, there are three factors: coconut export value, Thailand's coconut export price, and rainfall. Additionally, it was found that the value of Thailand's coconut exports to foreign countries has shown a clear upward trend every year.
