In this paper, we propose a design method for the construction of LTE-based small unmanned aerial vehicle control system to quickly and reliably collect multiple small unmanned aerial vehicle position information simultaneously flying all over the country. In particular, the main requirements are the network (N/W), hardware (H/ W), software(SW), Database(DB), development architecture, and business needs. To satisfy these requirements, N/W, H/W, SW, DB design, and architectural design plan were suggested regarding the design requirements of a small UAV system. To effectively control the small unmanned multi-party system in the system design, the architecture is divided into the front-end service area and the back-end service area according to the function and role of the unit system. In the front-end service area that grasps and controls the position and state of small unmanned aerial vehicles (UAVs), we have studied the design part that can be expanded to N through TCP/IP network by applying Client PC method.

Industrial control system was designed mainly in the form of analog in early days. However, necessity of digital system engineering is increasing recently because systems become complicated. Consequently, stability of digital systems is improved so most industrial control systems are designed with digital. Because Using digital design of Industrial control system is expanded, various threatening possibilities such as penetration or destruction of systems are increasing enormously. Domestic and overseas researchers accordingly make a multilateral effort into risk analysis and preparing countermeasures. In this paper, this report chooses common security requirement in industrial control system and nuclear control system through relevant guidelines analysis. In addition, this report suggests the development plan of nuclear cyber security system which will be an essential ingredient of planning approvals.

Over the last several years, regarding to the strategic items, the international community has seen governments make more formal commitments to adopt and implement effective export controls to counter the proliferation of weapons of mass destruction(WMD). United Nations Security Council Resolution 1540(that is "S/RES/1540") stands as the most important of these commitments. Many UN members already have export control laws and regulations in place to prevent the proliferation of weapons of mass destruction. Many members also participate in a variety of formal and informal international arrangements to coordinate their export control efforts. Nonetheless, each of these countries has its own unique legal framework for export controls. This generates considerable diversity in the construction of the specific national legal authorities. Over the last few years, however, a consensus over what constitutes the key elements of effective legal authorities for export controls has begun to emerge. Evidence for this development comes in the identification of best legal authorities or principles at several multilateral conferences on export controls.

This study is designed to examine international export control norms, analyze current national export control system and identify the problems thereof, presenting several proposals for development in the system. The Republic of Korea, as a signatory of non-proliferation treaties and multilateral export control regimes, is obligated to comply with the international non-proliferation and export control norms, irregardless of hard or soft laws. Korea's export control system has been implemented in earnest since 2005; however, it contains serious problems in terms of the legal system and objectives of relevant laws and regulations, terms and definitions of the items subject to export controls, catch-all requirements, brokering license, response to the U.S. re-export controls, and so on. Proposals for development in the system include (i) enacting an independent law integrating the current dual-use items export control law and regulations, (ii) making use of the term of "strategic items" as a uniform terminology replacing 'goods etc.', 'strategic goods(inclusive of technology)', 'strategic goods, etc.', 'WMD, etc.' so as to preclude any possibility of misunderstanding, (iii) rewriting the catch-all control requirements, (iv) introducing registration system of brokering firms, (v) including provisions to comply with U.S. reexport controls, and (vi) providing stakeholder with correct and full information on export controls.

At present, communication network for subway is making use of the train radio system for main network and normally established a base station every three subway station. It is talk over the telephone between a locomotive and the traffic control for careful train service. Besides, mobile telephone equipment is using for service improve and convenience to passengers such as 011, 016, 017, 019 and what not. However, the train radio system has been occurring a various problems when a state of emergency because it is able to compose only one communication route each base station zone. We could have improving like this problems through induce the TRS(Trunked Radio System), though because have been able to compose multilateral communication route in case of linking with LCX(Leaked Coaxial) cable which is established. Therefore, we could be able to a fitting meet the emergency as train firing etc.. and efficient use of limited frequency resources.

The WBAN(Wireless Body Area Network) supplies mobile convenience to our medical services. But if we have few effective control variables across this service deployment, the hidden distortions or defects of the system might threaten the lives and rights of the stakeholders. Therefore we need to increase the service credibility, to get WBAN effective. This study proposes a governance mechanism using feasible variables that are currently in use in practices in WBAN environments against medical incidents. Control variables were tested in Seoul National University hospital and related medical industries of South Korea. We assume that WBAN systems would be open based on integrating patients, medical employees and law enforcements to get smart theater operations against medical incidents by implementing proposed MJA(Multilateral Joint Analysis) model. MJA model also contributes to the convergence of computer systems and medical services by demonstrating flexible SOA(Service Oriented Architecture) dashboard of healthcare services with credibility factors in medicine. The important components in MJA model across WBAN, were found to be "Safety, Accuracy and Reliability" in priority order. Factor analysis, correlations and ANOVA were used to evaluate this model and an IT dashboard with a realization of mobile application, was used to support participants' decision-making.

Most existing industrial robots have fences installed around them to ensure safety. However, industrial sites are recently being transformed into workspaces shared by both robots and humans working cooperatively, wherein the robots are without security fencing owing to the development of sensor technology. However, in the last five years (2017-2021), 16 deaths have occurred due to robots at industrial sites, with the main cause of the accidents being workers approaching an industrial robot in operation and getting entangled with or colliding into the robot and its peripherals. To prevent such accidents, multilateral research is needed. To this end, this study analyzes the nonconforming contents of safety inspections for industrial robots and demonstrates the safety performance of the safety function control system implemented in an industrial robot cell. In addition, to ensure the fundamental safety of industrial robots, this study proposes the introduction of a safety certification system so that safety functions can be implemented in the design, manufacturing, and installation stages of the robots.

In this paper, we develop the system for audio volume equalization of video on demand(VoD) content and propose the solution for it. In recent years, there has been a steady increase in the number of VoD users in addition to linear channels. However, viewers ought to sit in an uncomfortable way, adjusting the volume intermittently while they are broadcasted. Sudden changes of volume occur between the broadcasting channels, the programs from the co-channel, or the linear channels and the VoDs. Especially, upsurged dissatisfaction from the televiewers has been found due to the unequalized volume when shifting between the linear channel and the VoD. In order to solve this problem, multilateral efforts were put forth, such as a system for keeping the volume at a certain level in digital broadcasting program has been legislated domestically. It leads success in equalizing linear channel volume. On contrary, too little notice has been taken for distorted volume problem of video on demand(VoD) content. In this paper, we developed and applied the volume equalization system into VoD content to achieve uniformization, a similar condition with linear channel(-24LKFS). This suggestion helped uneven current of volume which was in the stage -16 ~ -20LKFS to stable condition by lowering into the stage of -24LKFS. It also brought 20% increase in perspective of volume quality satisfaction level.

These days the automobile industry, which has rapidly progressed, has been an indispensable part in social and economic activities as well as its research and development have been activated in response to various needs of consumers and markets. The second and third generation control system, getting count on safety and convenience differently than early circuits, cause the hypertrophy of wire harness. The J/Box(Junction Box), which distributes power and wires, was developed to solve the problem. As vehicles have been better in quantity and intelligence, however, environment-friendly electric apparatus system has continuously increased and ITS(Intelligent Transport System) has been introduced in earnest. In result, wires got complicated and multilateral and also there has been a stronger probability that vehicles are out of order due to various problems including mechanical failure. In this study, ISJB(Intelligent Smart Junction Box) was introduced to solve the problem. The diagnosis system was applied to prevent the overload and short of ISJE. Also, the state of vehicles displayed so that drivers monitor it in motion. Likewise error data are saved in the memory so that such data can be analyzed retrospectively. The busbar was adopted in to the main power terminal and the part of power pattern was coverd by lead. Because ISJB is more sensitive to heat in comparison to the busbar type J/Box. With regard the circuits related with safe, alternative circuits were set up in order that electronic devices may be normally operated even when an error arises. ISJB is expected to improve the safety and quality of vehicles.

Under the UN Security Council Resolution 1540/1810 in 2004 to restrict the proliferation of WMD (weapons of mass destruction) and their means of delivery, many countries have taken great efforts to, control the export of strategic items, thereby preventing the transfer of ABCM (atomic, biological, chemical weapons, missiles) and technologies and goods related to conventional weapons or dual-use items, Compliance Program (CP) in Korea or Internal Compliance Program(ICP) in Japan refers to a company's internal system or rules to comply with the export control laws and regulations, and is to prevent the unintentional illegal export of strategic items. This paper analyzes the Compliance Program (CP) of strategic export control system between Korea and Japan. Both countries have very similar legal frameworks under the guiding principles of multilateral export control regimes. However, there are some differences in actual procedures, classification service, supporting system, export license, sanctions for illegal exporters, etc. Korea should take more active and customer-oriented measures to promote the Compliance Program (CP) into Korean export companies for better awareness and positive attitude, practical information and education, smoothy government-firm communication, closer cooperation between Korea and Japan, etc.
