Global advanced technology era is the most significant role for world population using Online Social Network (OSN) increasingly. It can be applied to multi-functioning purposes which are more essential for their life any situations for instance their society, study, and work. The integration of technology and English practicing skills has a lot good benefits for them to promote English communication among EFL learners. They are motivated and encouraged to practice their English skills more fluently and effectively. They also have good attitudes towards using the technology in their learning. Most of them are able to communicate in English with each other around the world. They also learn more culture and lifestyles in any foreign countries, especially in ASEAN countries. Thailand is one of the members in ASEAN Community that Thais need to communicate in English as a working language. They have to use English for their study and work in Thailand and other countries. It's very necessary to help them communicating in English direct oral conversations related to real work life with these foreigners rapidly. This article describes that Technology Enhanced Language Learning (TELL) impacts EFL Learners as social media to improve their English communication. Internet acts as an efficient tool to enhance language acquisition in English learning. Most of them use a lot of applications via smart phones for their English lifelong learning anywhere anytime. TELL assists them to practice more English communication skills which are important for their study and work life. They enable to learn all English such as vocabulary, grammar, expression, conversation, message, etc. They also develop their English communication skills; listening, speaking, reading, and writing any situations. They will be able to communicate with Asians in English for further work in ASEAN Community effectively. They will cooperate to do business for ASEAN Economic Community (AEC) in the future successfully.

We study the behaviors and the problem in changing the project topic during the last four years. We use primary sources to develop the concept and the decision support system. This research proposed the concept of making decision. The concept is used to apply to the problem when the students choose the final project. The process of the system is taken from regular project defense process to develop tree-like decision theory that will be the supporting model in P-DSS model. The P-DSS system analyzes the student's information on choosing the project in Information Technology and matches the skills, practices, and the curriculum regulations. © 2017 ACM.

Many automatic assessment (AA) tools have been developed and used to help the instructors grading the students. In computer science field, those AA tools are mainly focus on computer programming language course. However, with the development of the compiler and integrated development environment, the students can learn and practice programming while getting informative feedback without an AA tool. However, in the course that requires interaction with the operating system, the exercises can involve many programs and steps. Manually checking the student's machine takes a long time for the instructor. Furthermore, there is no AA tool that was designed specifically for grading this kind of exercise. In this paper, the framework for Linux-based operating system exercises called LINSIM is proposed. LINSIM obtains the state of the operating system in the student's machine and verifies if the system has been configured according to the exercise. The framework provides an abstraction between the LINSIM script and the Linux commands so that the instructor need not write custom commands. Finally, the prototype that implements the framework was developed and used in the classroom. As a result, the instructor can immediately provide the feedback on the exercise to the student. © 2017 ACM.

This paper presents the development of database management of Thailand Qualification Framework (M-TQF). The main objectives of the system are the educational quality assurance, reduced redundancy, verified submission, and document management of Thailand Qualification Framework (TQF). Then the satisfaction of the users to the system is evaluated. We analyzed the working process, designed, and evaluated the system in our previous work. In this paper, we continuously develop the system structure, ER diagram, the user interface, write the code and survey satisfaction of the user to the system. The study shows that the average of satisfaction is at the excellent level (4.26). Therefore, the result indicates that the system can support the document management of TQF in Rajamangala University of Technology Suvarnabhumi (RUS), support the educational quality assurance, solve the problem of the document management of TQF, and appropriately develop the Information Technology curriculum. © 2017 ACM.

This paper proposed the concept of using decision support system to integrate and utilize in term of admission to Higher Education in Thailand. We study the trends in 21st-century education, trends in transferring the curriculum of the students in Rajamangala University of Technology Suvarnabhumi (RUS) for seven years, and use the primary data to develop the model called A-DSS Model. The A-DSS model is the concept of developing the A-DSS system. The evaluation of the survey design that will be used to evaluate A-DSS system indicates that the system can support application and learning and teaching which help the RUS to filter the students according to background, skill, field to match the students' need and limitation of the University. © 2016 IEEE.

A class diagram is the heart of the object-oriented analysis and design. Understanding the meaning in class diagram is important for everyone who has involved in the software development project. This work proposes the method of automatically generating class description. The generation was done in two main steps. First, all class components in the class diagram input file are transformed into the tree data structure. Then, the system will generate the class description of that class components tree. This work proposes two types of the generation method according to the tree traversal method: top-down and level-order traversal. The example results show comprehensive class descriptions that can use in the future other works. © 2016 IEEE.

Many information on the Internet nowadays is produced by mobile phone and becomes location-aware. Since the information has evolved to be more complex, a generic location-aware rank query problem was proposed (GLRQ). GLRQ allows searching the objects with different searchable attributes such as spatial, textual, and numeric together. To search many different types of attribute efficiently, a hybrid index structure called Inverted Files R-Tree with synopses tree (IRS) was proposed. However, the IRS was not able to achieve the optimized performance as the only spatial location is the only attribute that is taken into account in tree construction. Then Multi-IRS technique was proposed to generate multiple optimized trees for each numeric data type. However, the textual attribute was not handled. This paper presents the optimization technique for a textual attribute which can be included in Multi-IRS. The experimental results show that our proposed method reduces I/O access cost by 50% on the real dataset. © 2016 IEEE.

Noise reduction is one of the most essential processes for image processing. The goal of the noise reduction is how to remove noise while keeping the important image features as much as possible. In this paper, a novel method to remove additive noise from digital image, based on the combination of Gaussian filter and the singular value decomposition, is proposed. Firstly, Gaussian filter is used to classify noisy image into two parts, which are its blur and noisy edge images. Next, the noise on noisy edge image, obtained from the difference between the original noisy image and its blur image, is reduced by using an adaptive block-based singular value decomposition filtering (BSVD). Finally, the reconstruction images are obtained from combining between noisy edge image, filtered by an adaptive BSVD filtering, and its original blur image. From the experiments, the objective and subjective measurements prove that the proposed approach compared with traditionally methods can suppress noise, preserve the significant image features as well as effectively smooth in the homogeneous area. Therefore, the proposed method leads to a practical method to be used for noise reduction.

We study, using N-body simulation, the shape evolution in gravitational collapse of cold uniform spherical system. The central interest is on howthe deviation from spherical symmetry depends on particle number N. By revisit of the spherical collapse model, we hypothesize that the departure from spherical symmetry is regulated by the finite-N density fluctuation. Following this assumption, the estimate of the flattening of relaxed structures is derived to be N-1/3. In numerical part, we find that the virialized states can be characterized by the core-halo structures and the flattenings of the cores fit reasonably well with the prediction. Moreover, the results from large N systems suggest the divergence of relaxation time to the final shapes with N.We also find that the intrinsic shapes of the cores are considerably diverse as they vary from nearly spherical, prolate, oblate or completely triaxial in each realization. When N increases, this variation is suppressed as the final shapes do not differ much from initial symmetry. In addition, we observe the stable rotation of the virialized states. Further investigation reveals that the origin of this rotation is related in some way to the initial density fluctuation. © 2014 The Authors.

The conventional CPW fed rectangular slot antenna create dual narrow band. The single wideband antenna can obtain by using tuning stub. This paper describes a modified tuning stub of CPW fed rectangular slot antenna to achieve single wide bandwidth. The prototype of tuning stub is designed with several parameters, the significant modified by cutting on vertical narrow strips of tuning stub to achieve four different geometries. The comparison on the simulated return loss shows the bandwidth, the widest bandwidth with good matching is choosing. The wide slot antenna fed by coplanar waveguide (CPW) with tuning stub is designed on low cost substrate FR4 to achieve single wide bandwidth coverage standard of WLAN IEEE 802.11b/g/j/a/n (2.4 -2.4835 GHz, 4.9-5.1 GHz, 5.15-5.35 GHz, 5.7-5.9 GHz) and WiMAX (3.5 GHz) from frequency range 2.29-6.94 GHz. ©ICROS.
