Development of elements of clothing laboratory management in Shaanxi Fashion Engineering University

Li Jiao — 2024-12-30

This study aims to explore in- depth the management needs of the
clothing laboratory at Shaanxi Fashion Engineering University. To achieve this,
we designed and conducted a questionnaire survey involving 282 clothing major
students and 78 teachers from the Fashion Institute. After completing data
collection, we applied rigorous procedures to process and analyze the data.
Statistical methods, including calculating the mean and standard deviation,
were used to quantitatively analyze the survey data and ensure accurate and
objective conclusions. And review by 6 experts.
The study identified eight key elements: 1) laboratory equipment
management, 2) data and document management, 3) laboratory access
management, 4) consumables management, 5) environment management, 6)
personnel management, 7) safety management, and 8) system management.
These eight elements comprehensively cover the management and
optimization of clothing laboratories in higher education institutions. From the
intelligent management of equipment, data, and documents to the precise
control of laboratory access, consumables, and environment, as well as
personnel training and incentives, the enhancement of safety protocols, and
the continuous improvement of management systems, these aspects
collectively promote the development of laboratories toward greater efficiency,
safety, and environmental sustainability.

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

Hathairat Theerakarn — 2024-12-30

Packaging design is important for business. Designing a standard package
that is outstanding will attract consumers' attention, which will affect sales. This
research is on the development of fried chili Tom Yum flavored packaging
according to packaging design standards. Case study: Fried chili establishment
Samut Sakhon Province. Objectives 1) study the fried chili packaging design of
the establishment and 2) design fried chili packaging according to packaging
design standards. The researcher collected data using interview forms and
observation forms and used packaging design principles to design fried chili
packaging. Research results: The original design of the establishment's fried chili
packaging is packaged in a normal clear ziplock plastic bag, which is not
outstanding and does not comply with packaging design principles. The
researchers designed two pieces of packaging, an individual package and an
inner package. Number of models: 2 and presented them to the establishment.
The establishment selected the first form of packaging. After the establishment
used the developed packaging, it could increase sales of fried chili products by
10,000 grams/month.

Design and Development of Dry Corn Peeling Machine to Enhance the Efficiency of the Corn Production Process for Animal Feed

Kwanchai Saeweenan — 2024-12-30

This research is conducted with the objective of designing and
developing a dry corn peeling machine for the corn production process in
animal feed. The machine is designed and built with a simple inclined corn
container, allowing the corn to flow smoothly without blockage. It uses a motor
to drive a belt and gears to transfer power from the pulley to the shaft, replacing
manual labor, which incurs high labor costs and can only peel 5 cobs per
minute, while also facing labor shortages. The results of testing the dry corn
peeling machine showed that the machine has a suitable size, is made from
strong and durable materials, and can peel dry corn with a moisture content
between 20-25% at a rate of 10 cobs per minute. This meets the set objectives
and is suitable for small-scale household industries.

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

Nithit Puntanagornpat — 2024-12-30

This study aims to 1) investigate the effects of wood type, wood
thickness, and cutting speed on the defect rate in the production process of
wooden furniture, and 2) determine the optimal cutting speed and wood
thickness to minimize the defect rate for each type of wood. Prior to
improvement, the average defect rate was 8. 37%, corresponding to a loss of
26,080 THB per month. The analysis utilized the General Linear Model ( GLM)
and Analysis of Variance ( ANOVA) to evaluate the effects of the three factors.
The results indicated that all factors significantly influenced the defect rate. The
optimal parameters identified were a cutting speed of 75 revolutions per minute
( RPM) and a wood thickness of 12 mm for both bagasse wood and particle
board. After implementing these improvements, the defect rate decreased to
3.52%, corresponding to a reduced loss of 9,338 THB per month, representing a
decrease of 16,742 THB or 64.19%. These findings demonstrate the efficiency of
using experimental design to reduce defects, lower storage costs, and minimize
time spent on corrective processes. Additionally, it alleviates the burden of
managing wasted resources, enhancing the logistics system's capability to meet
market demands efficiently and promptly.

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

Pornthip Liewtrakul — 2024-12-30

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 — 2024-12-30

This research aims to (1) study the coconut export situation of Thailand,
(2) identify factors affecting coconut exports from Thailand, and (3) analyze the
factors affecting coconut exports from Thailand using Multiple Regression
Analysis. The data used in the study are secondary data from the open
government data accounting system, with monthly data from January 2016 to
December 2023, covering a period of 84 months. From the literature review, the
researcher identified the factors related to coconut exports from Thailand
(independent variables), which include coconut export prices, export value,
rainfall, average temperature, and exchange rates. The dependent variable is
the volume of Thailand's coconut exports. The research findings show that three
factors significantly affect the volume of Thailand's coconut exports at the 0.05
significance level: export value, coconut export prices, and rainfall. Additionally,
it was found that the export value of Thai coconuts to foreign countries has
shown a clear upward trend every year. This information will be useful to
investors in the coconut business, both in the public and private sectors, to
mitigate risks from factors that impact the export of this product.
