ABSTRACT
Tanaka (Hesperethusa crenulata Roem) is an ancient herb that has been commonly
applied to the face as a skincare regiment. Gamma rays and X-rays are the wildly
used for improving microbiological safety of herbs. The aim of this study was to
compare the effect of gamma rays and X-ray radiation on microbiological quality,
color values (L*, a*, b*) and biochemical constituents of Tanaka powder. Tanaka
powder was irradiated with gamma rays and X-rays at doses of 5, 10, 15 and 20 kGy.
The results revealed that both gamma rays and X-ray irradiation at 5 kGy could
effectively decrease the number of microorganisms to below the detection limit.
Color values of gamma rays and X-rays irradiation were significantly decreasing of
lightness (L*) and a slight change in yellowness (b*) with increasing the irradiation
doses. In term of biochemical constituents such as arbutin content, sun protection
factor, total phenolic content and antioxidant properties, gamma and X-rays
irradiation were not influenced in a comparison with the non-irradiation Tanaka
powder. In conclusion, both method of irradiation decreased brightened the color,
while maintaining the arbutin content, sun protection factor, total phenolic content
and antioxidant properties of Tanaka powder.

ABSTRACT
The anti-obesity potential of Nipa (Nypa fruticans Wurmb.) vinegar was examined
using 3T3-L1 preadipocytes. The viability of 3T3-L1 preadipocytes was not affected
by the treatment with 5-70 mg/mL Nipa vinegar. The effect of Nipa vinegar on the
differentiation of 3T3-L1 preadipocytes to adipocytes was investigated. The cells
were incubated with the MDI differentiation medium in the presence of Nipa vinegar
for two days. From day 3 to day 10, the cells were maintained in the medium
containing FBS and insulin. Intracellular lipid accumulation was assessed by the Oil
Red O staining on day 10. A significant decrease in lipid accumulation was observed
upon treatment with 30-70 mg/mL Nipa vinegar (p<0.05). Moreover, apoptosis and
ROS generation of 3T3-L1 preadipocytes after exposure to Nipa vinegar were
evaluated using a flow cytometer. Exposure to 30-70 mg/mL Nipa vinegar induced
apoptosis higher than control (p<0.05). Nipa vinegar stimulated intracellular ROS
levels in a dose-dependent manner (p<0.05). Therefore, Nipa vinegar exhibited the
anti-obesity effect in vitro by inhibiting preadipocyte differentiation and inducing
apoptosis and ROS generation on 3T3-L1 preadipocytes.

ABSTRACT
MCM-22 is one type of zeolite which reported as high surface area and pore volume.
It can be applied in many industries such as biomass conversion, cracking, and dye
removal from wastewater. MCM-22 can be obtained by calcination of MCM-22(P),
the precursor synthesized by the hydrothermal process. Normally, the synthesis of
MCM-22(P) was used commercial silica and alumina sources as starting materials.
However, natural sources such as kaolin and rice husk were found that they contain
silica and alumina which required for the synthesis of zeolite. The result obtained by
many characterization techniques including X-ray diffraction (XRD), Fourier-
transform infrared spectroscopy (FT-IR), Raman spectroscopy, surface area and pore
size analysis, and Scanning electron microscopy were demonstrated that this work
was successful for the synthesis of MCM-22 zeolite by using natural kaolin and rice
husk as starting material by the hydrothermal process at 150ºC for 7days. The
obtained zeolite had a high surface area, more than 200 m2/g.

ABSTRACT
Zeolite NaY was synthesized and modified with cationic surfactants for CH4 and
CO2 gas adsorptions studies. The characterization results showed that the
modification of zeolite NaY did not lead to the change significantly in XRD patterns,
and the FTIR spectra presented the occurring of cationic surfactants onto zeolite
surface. The surface area analysis displayed the reduction of micropore surface area
due to the pore blockage form cationic surfactant whereas the external surface area
increased due to the coverage of cationic surfactant on zeolite surface. According to
the presence of phenyl trimethyl ammonium bromide (PTAB), the π-π linkage
between CO2 and aromatic of PTAB showed the highest adsorption capacity. Not
only PTAB enhanced the CO2 adsorption but the other cationic surfactants were also
showed the increasing of CO2 adsorbed on the sorbents that should be due the weak
hydrogen bond as CH-π interaction. The adsorption of CH4 on zeolite and its cationic
surfactant modifications were also showed the improvement which less than of CO2
about ten times. According to the results, the modification of cationic surfactant onto
zeolites’ surface might be advantage in the sorbent for biogas purification.

ABSTRACT
This research studied the effect of cadmium (Cd) on the growth of Thai mung bean
(Vigna radiata (L.) R. Wilczek). The mung bean was cultured in hydroponic solution
containing different concentrations of Cd (0, 0.1, 0.3 and 0.5 ppm) for 5 days. The
result showed a significant decrease in the lengths of root and shoot of mung bean
that was grown in cadmium solution. This effect was proportional to the
concentrations of Cd. To assess cell death in the root of mung bean, Evan’s blue
staining technique was used in this study. A concentration-dependent increase of
dead cells was found in the Cd-treated group, mostly at the root cap zone. With
respect to this result, the amount of dead cells that was stained with Evan’s blue dye
could be used as a biomarker to indicate cadmium contamination in the environment.
Furthermore, the effects of chelating agents (EDTA) on cadmium removal were also
studied. The results showed the possibility of using EDTA as a cadmium treatment
agent and promoted plant growth in cadmium contamination areas.

ABSTRACT
Biodiesel production process encourages use of heterogeneous catalyst over
homogeneous catalysts. The major problems associated with the use of
homogeneous catalysts are its non-renewable nature, separation and washing which
can be overcome by the use of heterogeneous catalysts. This study is focused on the
investigation of river snail shell improved with modified activated carbon (MAC) as
heterogeneous solid base catalyst for transesterification of palm oil. The calcium
oxide (CaO)/MAC catalyst was characterized by X-ray diffraction (XRD), scanning
electron microscopy (SEM) and Brunauer-Emmet-Teller (BET) method. The
operating parameters such as methanol to oil mole ratio, amount of catalyst, reaction
time and microwave electrical power were investigated in order to optimize the
reaction condition for the biodiesel production. As a result, the optimum reaction
parameters found were 12:1 methanol to oil mole ratio, 2.5 wt.% of the CaO/MAC,
4 min of reaction time and microwave electrical power at 600 watt. After further
reused for 5 times, the yield of biodiesel could still reach 90%, which indicated that
the novel catalyst had a good stability and recyclability. River snail shell can be
considered as a nature based benign and resourceful material for the biodiesel
production providing a new route for sustainability of fuels.

ABSTRACT
Among chemical fertilizer, phosphate fertilizers are the major sources of 232Th, a
naturally occurring radionuclide. The continuous application of P-fertilizers will not
only add nutrients to the soil but also significant amount of 232Th. Several studies
reported that repeated application of P-fertilizer may lead to a gradual accumulation
of 232Th in agricultural soils over time. In the study area, the practice of green manure
in maize system has been implemented by sunflower oil plant rotation crop to
improve the soil fertility and to reduce contaminants input to agricultural soil. In the
present paper, 232Th concentrations and associated health hazard risk in maize soil of
chemical fertilization, green manure incorporation with 30% reduction of fertilizer
and the control, no fertilization were performed and evaluated. The results revealed
that the 232Th values in the control treatment remained fairly constant and were the
lowest levels, while 232Th increased in treatments with fertilizer and green manure
incorporation. Chemical fertilizer treated soil had greater contents of 232Th than
green manure treatment through the maize growing seasons. The 232Th values
(Bq.Kg-1) ranged as follows 1.877 to 6.082 for control, 18.269 to 35.771 for chemical
fertilizer, and 13.108 to 21.747 for green manure incorporation. While the mean
annual effective dose (Sv.y-1) were determined to be 2.979 for control, 21.603 for
chemical fertilizer, and 12.625 for green manure amendment. The results of the
present investigation on 232Th concentrations and annual absorbed effective dose
were lower than the world average (0.07 mSv.y-1) and international recommended
standards of 0.1 mSv.y-1 recommended by World Health Organization (WHO). It is
concluded that the study area did not pose any potential public health risk and were
considered safe for agriculture.

ABSTRACT
This paper presents an experiment to verify the safety effect of resolving an open
capacitor failure by 4-pin capacitor structures or 2-pin capacitor structures by cut the
copper pattern of the printed circuit board (PCB). Both solutions to the problem of
open capacitor failure do not affect the next part of the circuit or devices in the
operating frequency range of 100 kHz to 500 kHz. This research analyses the effect
of using a 2-pin capacitor by cutoff the printed circuit board. The results of parallel
patterns of copper stripes were analyzed at different stages and frequency responses
analysis in the range of 100 kHz to 4.5 GHz based on a frequency response analysis
(FRA), which are experimental results of insertion loss (S21) and return loss (S11).
Using a conventional capacitor instead of a 4-pin capacitor of RT2010 type did not
show any harmful effects from self-oscillation within the circuit or from the external
circuit. The accuracy was verified by simulating the computer program and
measuring the test circuit.

ABSTRACT
Particulate matter (PM) in the indoor environment mostly affects our respiration
system because 80% of the spending time, people reside for an indoor activity. This
research objective focuses on investigating efficient ventilation systems and
improving the air quality by removing harmful soot particles by using Computer
Fluid Dynamics (CFD) technique. In the analyzing process, the effects of the
ventilation configuration's positions mainly focused on how to reduce concentration
particles efficiently. Initially, the CFD technique was used to capture the room
model's air movements and particle distributions. Due to the turbulent flow, the
standard k- turbulence model was involved in calculating the simulation's airflow
field. Discrete Phase Model (DPM) modeling was used to gain the particle
information on how it influenced the particle's propagation and deposition. As a
result, the small particle motions in forced ventilation systems were dominated by
the flow patterns. Due to different ventilation conditions, the particle’s paths and
residence times were used to discussed the capability of the current ventilation
system. Overall, the simulation results were reasonably in good agreement with
experimental data. In future work, the modeling techniques will be introduced for
redesigning the advanced ventilation system and the modifications to increase the
ventilation system's efficiency will be the crucial issue in discussions.

ABSTRACT
Avoiding equipment damages caused by the vacuum issue, the air-operated valves
are usually introduced to evacuate unwanted air in the water piping system. Some air
valves are designed for various operations of water piping systems. In this research,
a simple air-operated valve's performance was investigated using the Computational
Fluid Dynamic (CFD) technique (ANSYS Fluent). The focus is to particularly
observe the air valves' reflecting mechanism while releasing the air under different
flow operating conditions. In this preliminary study, a two-dimensional simulation
was proposed, and the boundary and conditions were from the actual experiment.
Specifically, the Volume of Fluids (VOF) method was employed to capture the
physical motion of two different fluid flows (water and air). Also, to save the
computational time, a turbulent model named k- RNG model was adopted for
calculating the Reynolds stress term. Operating at the higher flow rates (pressures)
at the inlet resulted in a faster rising of the ball valve, leading to inappropriate air
release. In the future work, the validation study will be performed, and later the
desired operating conditions could be found and suggested for improving the current
performance.

ABSTRACT
Searching documents on web pages is still a problem for users. As a result, users get
less effective searching. To solve this problem, classifying web pages is one way to
help users. This research presents the concept of auto-classification web pages with
a support vector machine method. The method is an algorithm which can be used to
solve webpage classification problems. Support-Vector Machine (SVM) is a
machine-learning technique that aims to represent data as points in space. An SVM
classification then finds a clear gap between data based on given classes and draws
a hyperplane. The SVM classification is the best one to separate all class data points
from those of another class. Machine learning techniques are used in the
development of models to distinguish both inappropriate and inappropriate web
pages. The research presented consists of 5 steps as follows: 1) Web page data
preparation. 2) Optimized data modifications include Word Segmentation, Stop
Words, Feature Generation, 3) Modeling with Support Vector Machine, 4)
performance evaluation results, and 5) summarize the research results. From SVM
classification evaluation, the results show that SVM technique shows Precision 98%,
Recall 82%, F-measure. 89%.

ABSTRACT
Purple rice (Oryza sativa L.) is popular planting and consuming in North and
Northeast in Thailand. The important pigment on the purple rice seed is anthocyanin
which has high antioxidant ability. Firstly, this research studied about the total
anthocyanin content of purple rice extracted using pulse electric technique by vary
extracting treatment at three levels of 2, 3 and 4 kilovolts/centimetres (kv/cm) in 1
Hz and variable with the pulse number of 0, 100, 300 and 500 pulses and extracted
by ethanol 50%. The experiment found that the extraction of purple rice gave total
anthocyanin less than the expectation. So that, to improve total anthocyanin content,
the extracting treatments changed to 6 kv/cm in 1 Hz with the number of pulses 1000,
3000, 4000 and 5000 pulses. The result showed that at 6 kv/cm with 3000 pulses
gave acceptable percentage of antioxidant activity (60.97 ± 0.64) which was
consistent with total anthocyanin content (2.499 ± 0.092 mg/l) whereas higher pulses
resulted in a decrease in percentage of antioxidant activity. The result means that
even though extracted by high pulse electric energy will increase total anthocyanin
content but also decrease the percentage of antioxidant activity too.

ABSTRACT
Fortification of mango properties using osmotic dehydration technique was
employed. The objective of this study was to determine the effects of adding
substances (ascorbic acid, gallic acid and calcium lactate) in a diluted solution (33
oBrix sucrose syrup) on the retention of nutritive and bioactive compounds of dried
mangoes. Mango cubes were subjected to osmotic dehydration step prior to drying
(hot air drying and freeze drying). The degradation kinetics of antioxidants were also
described. The results showed that the antioxidant properties of the fortified mango
significantly increased without a high sugar content. Unfortified mangoes lost
approximately 100% of ascorbic acid and 50% of antioxidant activity after storage
for 4 months. The kinetics of ascorbic acid and antioxidants were adequately
described by the first-order reaction (R2 0.85-0.99). Increasing antioxidant activity
of up to 50% was found by fortification with gallic acid, ascorbic acid, and calcium
lactate. Hot air drying could provide a good product when compared to freeze drying,
with similar antioxidant properties at the end of storage. Therefore, fortification of
foods with physiologically active compounds using osmotic dehydration technique
is proposed as an attractive method to develop functionally dehydrated fruits.

ABSTRACT
The effect of welding current on microstructure, mechanical properties and
corrosion behaviour of Flux-Cored Arc Welded (FCAW) ASTM A36 carbon steel
joints is studied in this work. The welding currents used in the experiment were 180,
200, 220, 240, and 260 amperes while corresponding to heat inputs of 1.242, 1.380,
1.518, 1.656, and 1.749 kJ/mm, respectively. The welding process was performed
by the Welding Procedure Specification (WPS), and Procedure Qualification Record
(PQR). Corrosion behaviour of the heat-affected zones, weldment, and base metal
were determined by Tafel polarization curves. It found that all the welding currents
in the heat-affected zones (HAZ) have been the highest corrosion rates when
compared to the weldments and the base metal. However, the effect of different
welding currents was measured by microstructures and hardness property on ASTM
A36 carbon steel to investigate the morphologies of fusion zone, HAZ, and base
metal after FCAW processes

ABSTRACT
This paper aims to present the comparison between AHP and FAHP used in Multiple
Criteria Decision Making (MCDM) to select the best medical device supplier
candidate. At present, it can be seen that the Fuzzy set is widely used in combination
with the Analytic Hierarchy Process (AHP) and is defined as Fuzzy Analytic
Hierarchy Process (FAHP). FAHP is notable among financial, energy, engineering
and other manufacture industries. In this study, the investigation and analysis on the
differences between the classic AHP and FAHP (Triangle, Trapezoidal) will be
conducted provided that the same set of data as been used in the medical device
distributor selection procedure. There are 5 decision criteria: price, payment terms,
delivery time, service, quality and 3 medical device suppliers are chosen and
analyzed in this paper. The result shows that, considering both AHP and FAHP
(Triangle, Trapezoidal), the weight of each criteria is quite similar with just a little
dissimilarity. The Consistency Ratio (CR) of classic AHP = 9.85%, Triangle FAHP
= 11.52% and Trapezoidal FAHP = 11.40%. Therefore, the consistency ratio of the
FAHP must be carefully monitored because it is more sensitive than the classic AHP.

ABSTRACT
This research aimed at improving the efficiency of Agarwood oil bottle filling using
quality control circle. By collecting information from establishment, the average
production and distribution amount is 1,500 litres per year (in 5 ml and 20 ml bottle
size). It is found that the Agarwood oil bottle filling cannot be processed in time
according to the customer need because of using human labor. The data from packing
100 Agarwood oil bottles for each size is collected and analyzed; the 5 ml bottle and
20 ml bottle filling required 6.30 minutes and 10.33 minutes, respectively. After
training and setting up the quality work group for analyzing and resolving the delay
in the bottle filling process using three technical tools: inspection sheet, cause-and-
effect diagram, and control chart, it is concluded that, by using a drilling machine to
adapt and develop the bottle cap press module and the slide rail to support Agarwood
oil bottles, the bottle filling time can be reduced. During the implementation of the
group activities in the establishment of the case study, the required filling time for 5
ml and 20 ml bottle size is 4.25 minutes and 6.12 minutes, respectively. Therefore,
the bottle filling time is reduced by 32.54% and 40.76%, respectively.

1,150 and 1,200 C˚, The mean grain size was 19.36, 21.34, 25.14, 33.57 and 42.66
µm, respectively. The average hardness results were 56.75, 54.22, 52.88, 52.64 and
51.72 HRC. Therefore concluded that low temperatures result in small grain sizes
and high hardness values. On the other hand, the higher temperature, the larger the
grain size and the lower the hardness. The results of simulation using finite element
method showed that the shape size was close to the actual work piece without any
defects and there are no nicks or dents. The force used in hot forging Consistent with
material behaviour and material properties test results. Therefore, the designer can
use the information to improve the hot forging process, determine the material
properties of the finished products and apply the finite element method to the design
of the part fabrication process.

ABSTRACT
The industrial cocoon production for being sold and taken to a woman as a silk thread
is well-known in Thailand. However, the quality of the cocoons does not meet the
needs of the entrepreneurs and the quality is not good because there is too much fluff
attached to the cocoon. So, this study is to design and build the fluff cocoon peeling
machine by studying the principles, and determine the work efficiency and evaluate
the performance of the fluff cocoon peeling machine. The test process used the
speeds at 380 400 and 420 rpm to peel the fluff cocoon. The results indicated that

ABSTRACT
Due to the epidemic of Coronavirus 2019 (COVID-19), consumer behavior
worldwide is changing. They are obliged to digital transactions amid physical store
closings. This change affects the growth of e-commerce. However, the success of e-
commerce is highly related to last mile delivery efficiency. The aim of this paper is
to compare the last mile delivery modes in Thailand by using Technique for Order
Preference by Similarity to Ideal Solution (TOPSIS) method. The criteria are used to
evaluate such as price, weight, delivery time, warranty, opening hours, service
center, retention period, and payment option. In Thailand, there are 4 last mile
delivery modes available as attended: home delivery, unattended home delivery,
maned collection point (Speed-d), and unmanned collection point (iBoxes). The
results indicate that attended home delivery is the most preferable and recommended
service mode in Thailand. This mode is widely used among online shoppers and still
popular for the consumers. On the other hand, iBoxes is the least preferable and
appropriate one, due to the reason that this mode is not available nationwide. Now,
it's only available in Bangkok and its vicinity.

ABSTRACT
In ancient times, the woven reed mat was weaved by a traditional method that thread
was only overturned and turned upside down on the loom. The original patterns
weren’t a novelty. Later, a pattern was designed for reed mat weaving by simulating
the pattern of Mee Khit fabric and some traditional cloth patterns. This research
applied the coupled Fibonacci sequences of third order modulo m and the knowledge
of the local community to a woven reed mat design with a variety of beautiful
patterns, which can add options and values to the reed mat products in the

ABSTRACT
Abstract. The present paper aims to show the significance of the notions of absorbing maps
and orbital continuity in common fixed point considerations. We prove that orbital
continuity of a pair of absorbing self-mappings of a complete metric space is equivalent to
the existence of a common fixed point in various settings. We also show that orbital
continuity of only one mapping is not equivalent to the existence of a common fixed point
of a pair self mappings satisfying contractive conditions.
Keywords: fixed point, orbital continuity, semi R-commuting, weak absorbing

ABSTRACT
Six samples of Pr3+ ions doped potassium aluminium gadolinium phosphate (KAGP)
were synthesized using the melt-quenching method. The values of density and
refractive index of glasses tend to rise with the concentration of Pr2O3 due to
increased interaction between the Pr3+ ions and non-bridging oxygen. Optical
absorption spectra and luminescence have been investigated. Hypersensitive
transitions were identified by the highest intensity of absorption spectra, which
recorded at the wavelengths of 444 and 1527 nm corresponding transitions 3H4→ 3P2
and 3H4→3F3. The emission bands of Pr3+ ions in the visible bands were observed
under the excitation 444 nm. Among them emission bands at 597 nm (1D2→3H4)
showed the highest intensity and the concentration quenching at 0.5 mol% for Pr3+,
the emission faster than those of 3P0 and 3P1 due to the cross-relaxation. The
Commission International De I'Eclairage (CIE) 1931 chromaticity coordinates of
KAGP glass doped Pr3+ at 0.5 mol% lie in yellowish-orange region to orange region.
Based on the studies characteristics, KAGP glass doped Pr3+ at 0.5 mol% was
suitable for guided as a great host that can emit yellowish-orange laser and suitable
for optical device also.

ABSTRACT
This work will present the effect of addition Calcium Fluoride in Lithium Phosphate
Oxide glass. The glass compositions based on 69P2O5–20Li2O–10Al2O3–1Sm2O3
and 59P2O5–20Li2O–10Al2O3–10CaF–1Sm2O3 are prepared by melting and
quenched technique. The physical, structural, optical and spectroscopic properties
have been investigated to determine the performance of calcium fluoride on lithium
phosphate oxide glass. The density and refractive index of glass without CaF have
higher values compared to glass added with CaF. The FTIR spectrum showed the
reduction of the O-H group in a glass added with CaF. The absorption band of Sm3+
ions starts from 6H5/2 as the ground state in the UV-Vis-NIR region. The
spectroscopic properties of the glasses have been obtained by using J-O analysis.
