In this study, we introduce the background and model for the Test of Practical Competency in ICT(TOPCIT), which is designed to diagnose and assess the competency of ICT industry related workers and software(SW) developers, and also attempt to derive meaningful policy implications for developing a global level of ICT SW competency evaluation system across the different cases in domestic and foreign countries with regard to the application and dissemination of the TOPCIT. First, we analyze the test results from surveys conducted a preliminary test (or a pilot test) for the process of global dissemination of the TOPCIT in 2015. Then, we attempt to compare the results with the domestic test results. The findings show that the average score between domestic and foreign test takers was similar, but in the highest score group, the number of domestic test takers was relatively higher than the number of foreign test takers. Moreover, the average score can be varied by the language ability, especially fluent in English, of test takers. Therefore, the findings suggest that the localization is one of the key components for building upon the global TOPCIT system.

The purpose of this study is to analyze the changes in trade and industry of Korea and suggest implications from the perspective of global value chains following the spread of COVID-19. To this end, products for prevention of epidemics which is directly related to COVID-19 and IT industries with high GVC participation were analyzed. Due to the spread of COVID-19, the variation in import and export of products for prevention of epidemics was large. In the case of masks, import and export of final goods changed drastically, but the change in intermediate goods was not significant relatively. Korea's IT industry has been differentiated according to major trading partners amid overall changes in GVCs which is summarized as higher forward participation and lower backward participation. While no particular change resulted from COVID-19 has yet been made directly, the need for diversification strategies should be taken into account at a time when the production links with China and Vietnam are close and the dependence on trade with these countries is high. The COVID-19 is still in progress, requiring corporate strategies and policy efforts to respond to changes in GVCs in the post-COVID-19 era.

Objectives : This study aims to report the effectiveness and safety of Korean medicine with thread embedding acupuncture in the treatment of trigeminal neuralgia (TN). Methods : A 73-year-old man who had suffered from severe facial pain for one year and who had had a healthy tooth extracted due to the pain is reported. He could not eat or sleep due to the severe pain. Acupuncture, thread embedding acupuncture, cupping, herbal steam, and herbal medicines were used for the treatment. Numeric Rating Scale (NRS) and adverse events were checked daily, and other outcomes (Baseline Evaluation, Visual Analogue Scale [VAS], Short Form Health Survey 36-Bodily Pain [SF-36 BP], and Patient Global Assessment [PGA]) were measured at hospital admission and discharge. During the follow-up examinations, his pain was evaluated roughly, without using any formal measurements, on the basis of a global assessment. Results : All measured parameters, including pain, quality of life, and patient satisfaction were noted to have improved at the time of discharge compared to admission: VAS from 10 to 1.5, NRS from 7-8 to 1-2, and SF-36 BP from 0 to 22.5, and the patient's global assessment was somewhat improved. He did not take any analgesics after discharge and noted only mild adverse events, like pain where the acupuncture and thread embedding acupuncture needles were inserted. His pain relief was maintained for 6 months. Conclusion : Korean medicine with thread embedding acupuncture might be a safe and effective treatment for TN. In the future, larger sample sizes and high quality randomized clinical trials are warranted to confirm its efficacy and safety.

Korean travel agencies that have been utilizing the Internet passively feel threatened as global online travel agencies are quickly permeating the Korean travel market. Under these circumstances, this study conducted a focused analysis on how ICT affects the business environment of travel agencies. Based on the analyzed data, it also presents coping strategies for the Korean travel agencies. First, it is imperative to accelerate platform development to counteract the distribution structure of global tourism products. Second, it is essential that travel agencies actively utilize big data, the new paradigm of technology where data are generated at high speed, high volume, and for numerous purposes. Third, it is necessary to actively utilize a travel blog marketing strategy. As a communication tool for travel agencies, the continuing development of the Internet highlights the usefulness of marketing activities using blogs. Finally, it is essential to provide each customer more specialized travel consultancy.

While the global food system prevails in America, the community food system is also spreading rapidly. The former, which is based on industrial agriculture, has negative impacts on family farms, food safety, and community development. In contrast, the latter has positive effects on farmers, consumers, communities, and the environment. Community food systems have been able to grow successfully through the participation of farmers and consumers, support of the federal and state governments, and the initiatives of NGOs. Food Circle, upon which this study focuses, is one of the community food systems based on the regional level. It is the outcome of the green movement in Kansas City, Missouri. The goal of Food Circle in Missouri is to retain and support rural family farms by connecting them with regional consumers. Its main activity is to collect data, including a directory of farmers and their regional products, and distribute this data to regional consumers. It is informally organized and entirely self funded. Although community food systems have several problems, their development is to continue in America. The food system in Korea has become a global one in recent decades, and agricultural problems and food safety issues are being generated as a result. The development of community food systems would be helpful in resolving these problems. In order to activate community food systems in Korea as seen in America's case, it would be necessary to have the imperative participation of both farmers and consumers, the support of the central and provincial governments, and the initiatives of NGOs.

Nowadays, GPS is used widely, especially in case which needs precise position information, such as car navigation systems and various kinds of position measuring instruments in an outdoor environment. According to their applications, there are many kinds of GPS receivers with different costs and error rates. The maximum error range of the general-purpose GPS receiver is within 30m, though the error rate depends on receiving rate of signal and weather condition. RTK(Real-Time Kinematic) and DGPS(Differential Global Positioning System) have more precise accuracy than the general-purpose GPS. However end users can't afford use them because of their high price and large size of equipments. In order for the end user to obtain precise position information, it is important that GPS receivers has portability and low price. In this study, we introduce a new system that offers precise position information using the DGPS mechanism satisfying low cost and portability.

The global performance of the 5MW OC4 semisubmersible floating wind turbine in random waves was numerically simulated by using the turbine-floater-mooring fully coupled and time-domain dynamic analysis program FAST-CHARM3D. There have been many papers regarding floating offshore wind turbines but the effects of second-order wave-body interactions on their global performance have rarely been studied. The second-order wave forces are actually small compared to the first-order wave forces, but its effect cannot be ignored when the natural frequencies of a floating system are outside the wave-frequency range. In the case of semi-submersible platform, second-order difference-frequency wave-diffraction forces and moments become important since surge/sway and pitch/roll natural frequencies are lower than those of typical incident waves. The computational effort related to the full second-order diffraction calculation is typically very heavy, so in many cases, the simplified approach called Newman's approximation or first-order-wave-force-only are used. However, it needs to be justified against more complete solutions with full QTF (quadratic transfer function), which is a main subject of the present study. The numerically simulated results for the 5MW OC4 semisubmersible floating wind turbine by FAST-CHARM3D are also extensively compared with the DeepCWind model test results by Technip/NREL/UMaine. The predicted motions and mooring tensions for two white-noise input-wave spectra agree well against the measure values. In this paper, the numerical static-offset and free-decay tests are also conducted to verify the system stiffness, damping, and natural frequencies against the experimental results. They also agree well to verify that the dynamic system modeling is correct to the details. The performance of the simplified approaches instead of using the full QTF are also tested.
