Despite this popularity, studying qualitative information, particularly focus-group meetings, creates a challenge to most practitioner inspectors. The Mons, also known as Raman is considered to be one of the earliest peoples in mainland South-East Asia and to be found in scattered communities in Thailand, around the central valley and even in Bangkok. The present project responds to the needs identified traditional Mon set menus based on the participation of Bang Kadi community in Bangkok, Thailand. The aim of this study was to generate Mon food set menus based on the participation of the community and to study Mon food in set menus of Bang Kadi population by focus-group interviews and discussions during May to October 2015 of Bang Kadi community in Bangkok, Thailand. Data were collected using (1) focus group discussion between the researcher and 147 people in the community, including community leaders, women of the community and the elderly of the community (2) cooking between the researcher and 22 residents of the community. After the focus group discussion, the results found that Mon set menus of Bang Kadi residents involved of Kang Neng Kua-dit, Kang Luk-yom, Kang Som-Kajaeb, Kangleng Puk-pung, Yum Cha-cam, Pik-pa, Kao-new dek-ha and Num Ma-toom and the ingredients used in cooking are mainly found in local and seasonal regime. Most of foods in set menus are consequent from local wisdom. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=focus%20groups" title="focus groups">focus groups</a>, <a href="https://publications.waset.org/abstracts/search?q=Mon%20Food" title=" Mon Food"> Mon Food</a>, <a href="https://publications.waset.org/abstracts/search?q=set%20menus" title=" set menus"> set menus</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangkok" title=" Bangkok"> Bangkok</a> </p> <a href="https://publications.waset.org/abstracts/44378/using-focus-groups-to-identify-mon-set-menus-of-bang-kadi-community-in-bangkok" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44378.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">414</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">314</span> The Effect of Micro/Nano Structure of Poly (ε-caprolactone) (PCL) Film Using a Two-Step Process (Casting/Plasma) on Cellular Responses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=JaeYoon%20Lee">JaeYoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Gi-Hoon%20Yang"> Gi-Hoon Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=JongHan%20Ha"> JongHan Ha</a>, <a href="https://publications.waset.org/abstracts/search?q=MyungGu%20Yeo"> MyungGu Yeo</a>, <a href="https://publications.waset.org/abstracts/search?q=SeungHyun%20Ahn"> SeungHyun Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyeongjin%20Lee"> Hyeongjin Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=HoJun%20Jeon"> HoJun Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=YongBok%20Kim"> YongBok Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Minseong%20Kim"> Minseong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=GeunHyung%20Kim"> GeunHyung Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the important factors in tissue engineering is to design optimal biomedical scaffolds, which can be governed by topographical surface characteristics, such as size, shape, and direction. Of these properties, we focused on the effects of nano- to micro-sized hierarchical surface. To fabricate the hierarchical surface structure on poly(ε-caprolactone) (PCL) film, we employed a micro-casting technique by pressing the mold and nano-etching technique using a modified plasma process. The micro-sized topography of PCL film was controlled by sizes of the micro structures on lotus leaf. Also, the nano-sized topography and hydrophilicity of PCL film were controlled by a modified plasma process. After the plasma treatment, the hydrophobic property of the PCL film was significantly changed into hydrophilic property, and the nano-sized structure was well developed. The surface properties of the modified PCL film were investigated in terms of initial cell morphology, attachment, and proliferation using osteoblast-like-cells (MG63). In particular, initial cell attachment, proliferation and osteogenic differentiation in the hierarchical structure were enhanced dramatically compared to those of the smooth surface. We believe that these results are because of a synergistic effect between the hierarchical structure and the reactive functional groups due to the plasma process. Based on the results presented here, we propose a new biomimetic surface model that maybe useful for effectively regenerating hard tissues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20surface" title="hierarchical surface">hierarchical surface</a>, <a href="https://publications.waset.org/abstracts/search?q=lotus%20leaf" title=" lotus leaf"> lotus leaf</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-etching" title=" nano-etching"> nano-etching</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20treatment" title=" plasma treatment"> plasma treatment</a> </p> <a href="https://publications.waset.org/abstracts/40656/the-effect-of-micronano-structure-of-poly-e-caprolactone-pcl-film-using-a-two-step-process-castingplasma-on-cellular-responses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40656.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">376</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">313</span> Understanding the Effective of Cuisine Experience, Emotions on Revisit Intentions: The Case Study of Lu-Kang</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=An-Na%20Li">An-Na Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying-Yu%20Chen"> Ying-Yu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang-Kuang%20Chiou"> Chang-Kuang Chiou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Food tourism is one of the growing industries and areas of interest in the tourism industry today.

The stress of strands in the transfer length zone is smaller than that in the strain plateau zone, so-called effective prestress, therefore the web-shear strength in transfer length region is smaller than that in the strain plateau zone. Although the transfer length is main key factor in the shear design, a few analytical researches have been conducted to investigate the transfer length. Therefore, in this study, a theoretical approach was used to estimate the transfer length. The bond stress developed between the strands and the surrounding concrete was quantitatively calculated by using the Thick-Walled Cylinder Model (TWCM), based on this, the transfer length of strands was calculated. To verify the proposed model, a total of 209 test results were collected from the previous studies. Consequently, the analysis results showed that the main influencing factors on the transfer length are the compressive strength of concrete, the cover thickness of concrete, the diameter of prestressing strand, and the magnitude of initial prestress. In addition, the proposed model predicted the transfer length of collected test specimens with high accuracy.

Various sorting machines are used in the industrial field such as those operating under electrical properties, centrifugal force, wind power, vibration, and magnetic force. Study on separators has been carried out to contribute to the environmental industry. In this study, we perform CFD analysis for understanding the basic mechanism of the separation of waste concrete (fine aggregate) particles from air with a machine built with a rotor with blades. In CFD, we first performed two-dimensional particle tracking for various particle sizes for the model with 1 degree, 1.5 degree, and 2 degree angle between each blade to verify the boundary conditions and the method of rotating domain method to be used in 3D. Then we developed 3D numerical model with ANSYS CFX to calculate the air flow and track the particles. We judged the capability of particle separation for given size by counting the number of particles escaping from the domain toward the exit among 10 particles issued at the inlet. We confirm that particles experience stagnant behavior near the exit of the rotating blades where the centrifugal force acting on the particles is in balance with the air drag force. It was also found that the minimum particle size that can be separated by the machine with the rotor is determined by its capability to stay at the outlet of the rotor channels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20industry" title="environmental industry">environmental industry</a>, <a href="https://publications.waset.org/abstracts/search?q=separator" title=" separator"> separator</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=fine%20aggregate" title=" fine aggregate"> fine aggregate</a> </p> <a href="https://publications.waset.org/abstracts/37667/investigation-of-the-operational-principle-and-flow-analysis-of-a-newly-developed-dry-separator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37667.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">595</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">310</span> Fabrication of Hybrid Scaffolds Consisting of Cell-laden Electrospun Micro/Nanofibers and PCL Micro-structures for Tissue Regeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=MyungGu%20Yeo">MyungGu Yeo</a>, <a href="https://publications.waset.org/abstracts/search?q=JongHan%20Ha"> JongHan Ha</a>, <a href="https://publications.waset.org/abstracts/search?q=Gi-Hoon%20Yang"> Gi-Hoon Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=JaeYoon%20Lee"> JaeYoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=SeungHyun%20Ahn"> SeungHyun Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyeongjin%20Lee"> Hyeongjin Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=HoJun%20Jeon"> HoJun Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=YongBok%20Kim"> YongBok Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Minseong%20Kim"> Minseong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=GeunHyung%20Kim"> GeunHyung Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tissue engineering is a rapidly growing interdisciplinary research area that may provide options for treating damaged tissues and organs. As a promising technique for regenerating various tissues, this technology requires biomedical scaffolds, which serve as an artificial extracellular matrix (ECM) to support neotissue growth. Electrospun micro/nanofibers have been used widely in tissue engineering because of their high surface-area-to-volume ratio and structural similarity to extracellular matrix. However, low mechanical sustainability, low 3D shape-ability, and low cell infiltration have been major limitations to their use. In this work, we propose new hybrid scaffolds interlayered with cell-laden electrospun micro/nano fibers and poly(caprolactone) microstructures. Also, we applied various concentrations of alginate and electric field strengths to determine optimal conditions for the cell-electrospinning process. The combination of cell-laden bioink (2 ⅹ 10^5 osteoblast-like MG63 cells/mL, 2 wt% alginate, 2 wt% poly(ethylene oxide), and 0.7 wt% lecithin) and a 0.16 kV/mm electric field showed the highest cell viability and fiber formation in this process. Using these conditions and PCL microstructures, we achieved mechanically stable hybrid scaffolds. In addition, the cells embedded in the fibrous structure were viable and proliferated. We suggest that the cell-embedded hybrid scaffolds fabricated using the cell-electrospinning process may be useful for various soft- and hard-tissue regeneration applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioink" title="bioink">bioink</a>, <a href="https://publications.waset.org/abstracts/search?q=cell-laden%20scaffold" title=" cell-laden scaffold"> cell-laden scaffold</a>, <a href="https://publications.waset.org/abstracts/search?q=micro%2Fnanofibers" title=" micro/nanofibers"> micro/nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28caprolactone%29" title=" poly(caprolactone)"> poly(caprolactone)</a> </p> <a href="https://publications.waset.org/abstracts/40640/fabrication-of-hybrid-scaffolds-consisting-of-cell-laden-electrospun-micronanofibers-and-pcl-micro-structures-for-tissue-regeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40640.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">380</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">309</span> Exploring the Effects of Cuisine Experience, Emotions, Place Attachment on Heritage Tourists’ Revisit Behavioral Intentions: The Case Study of Lu-Kang</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=An-Na%20Li">An-Na Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying-Yu%20Chen"> Ying-Yu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Lung%20Lin"> Yu-Lung Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Food tourism is one of the growing industries in the tourism industry today.

Furthermore, the scaffold morphology (such as pore size, porosity and pore interconnectivity) plays an important role. The electrospinning process has been widely used to fabricate micro/nano-sized fibres. Electrospinning allows for the fabrication of non-woven meshes containing micro- to nano-sized fibers providing high surface-to-volume area for cell attachment. Due to its advantageous characteristics, electrospinning is a useful method for skin, cartilage, bone, and nerve regeneration. In this study, we fabricated PCL scaffolds (SP) consisting of spiral-like struts using 3D melt-plotting system and micro/nanofibers using direct electrospinning writing. By altering the conditions of the conventional melt-plotting method, spiral-like struts were generated. Then, micro/nanofibers were deposited selectively. The control scaffold composed of perpendicular PCL struts was fabricated using the conventional melt-plotting method to compare the cellular activities. The effect on the attached cells (osteoblast-like cells (MG63)) was evaluated depending on the bending instability of the struts. The SP scaffolds showed enhanced biological properties such as initial cell attachment, proliferation and osteogenic differentiation. These results suggest that the SP scaffolds has potential as a bioengineered substitute for soft and hard tissue regeneration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell%20attachment" title="cell attachment">cell attachment</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20strength" title=" mechanical strength"> mechanical strength</a>, <a href="https://publications.waset.org/abstracts/search?q=melt-plotting" title=" melt-plotting"> melt-plotting</a> </p> <a href="https://publications.waset.org/abstracts/45197/fabrication-of-3d-scaffold-consisting-of-spiral-like-micro-sized-pcl-struts-and-selectively-deposited-nanofibers-as-a-tissue-regenerative-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45197.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">317</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">307</span> On Chvátal’s Conjecture for the Hamiltonicity of 1-Tough Graphs and Their Complements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shin-Shin%20Kao">Shin-Shin Kao</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuan-Kang%20Shih"> Yuan-Kang Shih</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsun%20Su"> Hsun Su</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we show that the conjecture of Chv tal, which states that any 1-tough graph is either a Hamiltonian graph or its complement contains a specific graph denoted by F, does not hold in general.

The dermal papilla cells (DPCs) have known to regulate hair growth cycle and length of hair follicle through interact with epithelial cells. When immortalized vibrissa DPCs were treated with the U. peterseniana extract, the U. peterseniana extract significantly increased the proliferation of DPCs. The effect of U. peterseniana extract on the growth of vibrissa follicles was also examined. U. peterseniana extract significantly increased the hair-fiber lengths of the vibrissa follicles. Hair loss is partly caused by dihydrotestosterone (DHT) binding to androgen receptor in hair follicles, and the inhibition of 5α-reductase activity can prevent hair loss through the decrease of DHT level. The U. peterseniana extract inhibited 5α-reductase activity. Minoxidil, a potent hair-growth agent, can induce proliferation in NIH3T3 fibroblasts by opening KATP channels. We thus examined the proliferative effects of U. peterseniana extract in NIH3T3 fibroblasts. U. peterseniana extract significantly increased the proliferation of NIH3T3 fibroblasts. Tetraethylammonium chloride (TEA), a K+ channel blocker, inhibited U. peterseniana-induced proliferation in NIH3T3 fibroblasts. These results suggest that U. peterseniana could have the potential to treat alopecia through the proliferation of DPCs, the inhibition of 5α-reductase activity and the opening of KATP channels.

Intercultural communication competency (ICC) is a way of being that benefits all members of a society in their living, learning, and working environments as well as in the context of mediated communications. This study examines the effects of self-reflection processes on the improvement of intercultural communication skills focusing on college students at the University of Arkansas-Fort Smith. A total of sixty-nine students’ works were analyzed based on the data collected in the past three years (2016, 2017 and 2018). The students in the ‘Culture and Communication’ class, each spring, completed the Diversity Awareness Profile (DAP) survey as a pre- and post-test for the course. DAP is a self-assessment tool designed by Karen Stinson and widely used in college classes, companies, and organizations to evaluate an individual’s behaviors in various intercultural settings. It can assist individuals in becoming more aware of diversity issues and also provide a foundation for developing strategies for modifying any undesirable behavior they may discover in the assessment. In addition to the DAP surveys, the students also submitted self-reflection essays that discussed their own scores. The University of Arkansas-Fort Smith is a small regional university located in the Bible Belt of the United States. White, Christian, working-class students dominate its student population. The students, whose data were collected, were predominantly seniors in college majoring in either Media Communication or International Business. Approximately, 80% of the students increased their scores, and 42% of them moved forward to a new category. The findings also indicate that the students in the underrepresented groups (i.e., women, minority, and international students) show less change in their scores and behaviors than the rest of the students (i.e., white heterosexual male students). These findings, in most part, result from the fact that the underrepresented students were already aware of diversity and intercultural issues through their personal experiences before taking the class. The white heterosexual male students demonstrated the greatest improvements, judging from their DAP scores (pre- and post-tests) and self-reflection essays. Through the class assignments and discussions, which emphasized critical thinking and self-reflection, the latter group of students not only became more aware of the meaning of their own words and behaviors, but they were also able to develop greater proficiency in intercultural communication. This e-poster presentation will analyze the findings of this research data, and also discuss the pedagogical implications of such results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross-cultural%20communication" title="cross-cultural communication">cross-cultural communication</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity%20awareness%20survey" title=" diversity awareness survey"> diversity awareness survey</a>, <a href="https://publications.waset.org/abstracts/search?q=self-reflection" title=" self-reflection"> self-reflection</a>, <a href="https://publications.waset.org/abstracts/search?q=underrepresented%20students" title=" underrepresented students "> underrepresented students </a> </p> <a href="https://publications.waset.org/abstracts/97220/the-effects-of-self-reflections-on-intercultural-communication-competency-a-case-study-of-the-university-of-arkansas-fort-smith" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97220.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">290</span> Design of Cloud Service Brokerage System Intermediating Integrated Services in Multiple Cloud Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dongjae%20Kang">Dongjae Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Sokho%20Son"> Sokho Son</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinmee%20Kim"> Jinmee Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cloud service brokering is a new service paradigm that provides interoperability and portability of application across multiple Cloud providers.

In the results, we found assumptions of activity state classification seem to be sufficient and reasonable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activity%20status" title="activity status">activity status</a>, <a href="https://publications.waset.org/abstracts/search?q=fitness%20tracker" title=" fitness tracker"> fitness tracker</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20rate" title=" heart rate"> heart rate</a>, <a href="https://publications.waset.org/abstracts/search?q=steps" title=" steps"> steps</a> </p> <a href="https://publications.waset.org/abstracts/83758/activity-data-analysis-for-status-classification-using-fitness-trackers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83758.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">384</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">286</span> 3D Printed Multi-Modal Phantom Using Computed Tomography and 3D X-Ray Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sung-Suk%20Oh">Sung-Suk Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Bong-Keun%20Kang"> Bong-Keun Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang-Wook%20Park"> Sang-Wook Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hui-Jin%20Joo"> Hui-Jin Joo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Ryul%20Choi"> Jong-Ryul Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-Jun%20Lee"> Seong-Jun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong-Woo%20Sohn"> Jeong-Woo Sohn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The imaging phantom is utilized for the verification, evaluation and tuning of the medical imaging device and system. Although it could be costly, 3D printing is an ideal technique for a rapid, customized, multi-modal phantom making. In this article, we propose the multi-modal phantom using 3D printing. First of all, the Dicom images for were measured by CT (Computed Tomography) and 3D X-ray systems (PET/CT and Angio X-ray system of Siemens) and then were analyzed. Finally, the 3D modeling was processed using Dicom images. The 3D printed phantom was scanned by PET/CT and MRI systems and then evaluated. <p class="card-text"><strong>Keywords:</strong> <a
