The export of agricultural, fisheries, and food products acts as an engine of growth for developing countries in particular. However, exporting these items is easier said than done since issues of certification and inspection, so-called technical barriers to trade (TBT) and sanitary and phytosanitary measures (SPS), in developed markets have worked as major obstacles for exports. This paper examines the institutional aspects and recent trends of South Korea's TBT/SPS-related cases against exporting firms of the developing countries. We suggest a win-win partnership model that can promote cooperative synergies between Korea and developing employing trade-related technical cooperation or ODA (Official Development Aid). Technical cooperation such as the provision of on-spot field consulting services on TBT/SPS-related issues for exporting firms and Korean OEM firms of developing countries can lead to mutual gains. This cooperative partnership can create gains from "the trade-development nexus" for both sides while promoting sustainable trade and investment relationships between Korea and developing countries.

This studies the relationship between ODA and export performance of donor countries in Myanmar. This study analyzes 19 donor countries from 2002 to 2014 by using gravity model. The results show that ODA improves the export performance of donor countries in Myanmar in the period. The larger the amount of ODA, the larger the exports in Myanmar. And the rate of increase of ODA is also important in determining the export performance. These imply that ODA increases donor's export directly as well as indirectly by improving the relationship between donors and receivers. These results are important for Korea that is increasing ODA into Myanmar. Korea should search for a mode of ODA supporting as well as the amount of ODA.

Learning assistance system that continuously measures user's concentration will be helpful to grasp the concentration pattern and adjust the learning method accordingly to improve the learning efficiency. Although a lot of various learning aids have been proposed, there have been few studies on the concentration monitoring system in real time. Therefore, in this study, we developed an Android-based mobile application that can measure concentration during study by using functional near-infrared spectroscopy, which is used to measure brain activity. First, the task accuracy was predicted at a maximum level of 93.75% from the prefrontal oxygenation characteristics measured while performing the visual Q&A task on 11 college students, and a concentration calculation formula based on a linear regression model was derived. Then, a survey on the usability of the mobile application was conducted, overall high satisfaction and positive opinions were obtained. From these findings, this application can be used as a customized learning aid application for users, and further, it can help educators improve the quality of classes based on the level of concentration of learners.

Sensor Nodes play a major role to monitor and sense the variations in physical space in various real-time application scenarios. These nodes are powered by limited battery resources and replacing those resource is highly tedious task along with this it increases implementation cost. Thus, maintaining a good network lifespan is amongst the utmost important challenge in this field of WSN. Currently, energy efficient routing techniques are considered as promising solution to prolong the network lifespan where multi-hop communications are performed by identifying the most energy efficient path. However, the existing scheme suffer from performance related issues. To solve the issues of existing techniques, a novel hybrid technique by merging particle swarm optimization and game theory model is presented. The PSO helps to obtain the efficient number of cluster and Cluster Head selection whereas game theory aids in finding the best optimized path from source to destination by utilizing a path selection probability approach. This probability is obtained by using conditional probability to compute payoff for agents. When compared to current strategies, the experimental study demonstrates that the proposed GTPSO strategy outperforms them.

In a nuclear reactor, gamma radiation is the dominant energy deposition in non-fuel regions. Heat is generated upon gamma deposition and consequently affects the mechanical and thermal structure of the material. Therefore, the safety of samples should be carefully considered so that their integrity and quality can be retained. To evaluate relevant parameters, an in-core gamma thermometer (GT) was used to measure gamma heating (GH) throughout the operation of the McMaster nuclear reactor (MNR) at four irradiation sites. Additionally, a Monte Carlo reactor physics code (Serpent-2) was utilized to model the MNR with the GT located in the same irradiation sites used in the measurement to verify its predictions against measured GH. This research aids in the development of modeling, calculation, and prediction of the GH utilizing Serpent-2 as well as implementing a new GH measurement at the MNR core. After all uncertainties were quantified for both approaches, comparable GH profiles were observed between the measurements and calculations. In addition, the GH values found in the four sites represent a strong level of radiation based on the distance of the sample from the core. In this study, the maximum and minimum GH values were found at 0.32 ± 0.05 W/g and 0.15 ± 0.02 W/g, respectively, corresponding to 320 Sv/s and 150 Sv/s. These values are crucial to be considered whenever sample is planned to be irradiated inside the MNR core.

Because the psychophysical symptoms of hearing loss and dementia in the elderly are very similar, untrained healthcare professionals in dementia facilities can easily overlook a severity of hearing loss in their patients. The present study identifies their knowledge, attitudes, and practices (KAP) on hearing loss using a survey whether they may help hearing problem of the patients with dementia. A total of 29 health-care professionals responded to the KAP survey. Also, 2 family members participated. The results showed that most of the nurses and caregivers in elderly medical welfare facilities who worked with dementia patients did not have knowledge of their hearing loss. Even the facility managers did not know how to conduct hearing tests for their patients although they did recognize that some of their patients had a hearing loss. Eventually, actual practice was not possible at this moment by the professionals. However, our respondents did have a positive attitude toward screening for hearing loss and help their patients with dementia wear hearing aids if a clinical guideline was provided. We suggest to develop clear and precise clinical guidelines of the hearing screening test for the dementia patients due to the interrelationship between dementia and hearing loss. When these guidelines apply to elderly residents in a medical welfare facility, early diagnosis and treatment of their sensory loss will help alleviate their dementia as well.

With the aim of examining the effects of implementing international financial reporting standards (IFRS) on teaching accounting and auditing at universities and colleges in Vietnam, a case study was conducted at 30 universities, colleges, and 208 lecturers in Vietnam. Next, the study employed the structural model analysis method by PLS_SEM software to process and analyze the collected data. The research results show that: (1) There are eight factors that affect how IFRS is applied to teaching, including the training program, (ii) teaching staff, (iii) IFRS application regulations, (iv) related party requirements, (v) faculty/school administrators, (vi) teaching aids, (vii) IFRS teaching methods, and (iii) students; (2) there are three factors that affect the quality of teaching staff, including applying IFRS to teaching at the university and colleges, (ii) Regulations on the application of IFRS, (iii) Requirements from related parties. At the same time, the study also shows that, regarding the indirect relationships, applying IFRS to teaching does not play an intermediary role in these relationships. However, at the 10% significance level, it was found that there is an indirect relationship between regulations on the application of IFRS by the Ministry of Finance and the quality of teaching staff through the variable applying IFRS to teaching.

As demands for the maritime communications increase, a variety of functions and information are required to exchange via elements of maritime systems, which leads communication traffic increases in maritime frequency bands, especially in VHF (Very High Frequency) band. Thus, effective resource management is crucial to the future maritime communication systems not only to the typical terrestrial communication systems. VHF data exchange system (VDES) enables to utilize more flexible configuration according to the communication condition. This paper focuses on the VDES communication system among VDES terminals such as shore stations, ship stations and aids to navigation (AtoN) to address efficient resource allocation. We propose a resource management method considering a MIMO (Multiple Input Multiple Output) technique in VDES, which has been widely used for modern terrestrial wireless networks but not for marine environments by scheduling the essential communication resources. We introduce the general channel model in marine environment and give two metrics, spectral and the energy efficiencies to examine our resource scheduling algorithm. Based on the simulation results and analysis, the proposed method provides a possibility to enhance spectral and energy efficiencies. Additionally, we present a trade-off relationship between spectral and energy efficiencies. Furthermore, we examine the resource efficiencies related to the imperfect channel estimation.
