South Korea has been storing UNF in spent fuel pool dry storage facility within Nuclear Power Plants. The dry storage facility of used nuclear fuel (UNF) is essential to sustain safety and sustain stable operation of a nuclear power plant. Most abroad countries have attempted to develop a variety of dry storage facility for used nuclear fuel in order to retain the safe restoration. Many studies have been conducting to safety evaluation for the dry storage facility. However, there is not a ventilation evaluation in the wake of fire event that could influence of the thermal effect on the dry storage facility, even though it will likely to occur fire events such as wildfire, air craft crash. In practice, it happened to catastrophic disaster due to the wild fire adjacent to ul-jin mountain. Also, it happened to fire accident near to the Japonia NPP in Ukraine territory caused of military air plane missile. It has not mostly been studied on the ventilation evaluation considered to thermal safety in the dry storage facility excepted for some researches. It could need the mechanical ventilation systems such as HVAC system in the dry storage system, so that thermal effect can be reduced. In this study, we conducted to the ventilation control modelling by using fire modelling tool (Fire Dynamic Simulator v.6.7). The ventilation scenarios made up for 3 case that can compare flowrate variation with ventilation control. As a result of modelling, there is no differentiation between ventilation control using performance curve with not using performance curve even though the pressure fluctuation would be increased, compared with the case of considering performance curve. Second, it evaluated that the mode for fraction control would occur to pressure rise in the state of controlling the ventilation system flowrate. However, sensitivity of flowrate control was more decreased below less than 5 seconds. Third, in the case of on/off control system revealed more higher resolution than other cases caused by flowrate variation. These results could be considered as the design guidelines for the development dry storage facility to improve the thermal performance that can reduce thermal risk. Furthermore, the study results would expect HVAC system installed in dry storage to help automatic ventilation control relevant to dry storage safety increased.

The Nuclear Safety and Security Commission (NSSC) and the Korea Institute of Nuclear Nonproliferation and Control (KINAC) operate the Nuclear Export and Import Control System (NEPS), an online comprehensive export and import control management system to guide the domestic nuclear export and import control regime and efficiently process the application, processing, and issuance of various civil complaints required for compliance. This paper analyzes the results of NEPS functional improvements made in 2022. First, NSSC and KINAC launched a nuclear plant technology follow-up system. Since establishing the Nuclear Plant Technology Export License (Plant License) system in 2015, large-scale nuclear power plant projects with a large amount of technology transfer have been issued a Plant License, allowing them to transfer technology without a separate individual export license. The recipient of a Plant License is not required to obtain an additional export license but to follow up on the transferred technology, such as checking whether it is a strategic technology and reporting quarterly transfer details. A dedicated system has been established to facilitate the follow-up of plant license projects. That has improved work efficiency for both the regulated and the regulator. Second, we have improved the procedures for retrieving and supplementing civil petitions. We added a function allowing civil petitioners to directly retrieve a civil petition to cancel a previously filed civil petition or to revise it themselves. In addition, we improved the procedure for supplementing a civil petition by setting a supplementation deadline for a reviewer’s request to modify a civil petition and sending a reminder before the expiration of the supplementation deadline. That enhances the convenience of the complainant and the examiner. Finally, we have changed the numbering system for export and import control reviews. Previously, the application number was a 15-digit system with an 8-digit date and 7-digit serial number. We have simplified the number by changing the three unused digits in the serial number to a single symbol that separates the type of application. That made it possible to utilize the number for relevant searches in the future. Also, simplifying the number has improved the efficiency of applying, processing, and consulting for civil affairs. In the future, NSSC and KINAC will continue to upgrade NEPS and make various functional improvements, and there will be many changes in system operation through cloud transfer in a few years.

About 83% of the information systems of administrative and public agencies are operated by agencies, and most of them are vulnerable to security due to the small scale of operation, insufficient facilities, and lack of dedicated personnel. To address these issues, the Ministry of the Interior and Safety announced in June 2021 that, as part of the “Second Basic Plan for E-Government,” all information systems of administrative and public agencies will be converted to a cloud-based integrated management operating environment by 2025 to provide stable public services. Accordingly, relevant laws and guidelines should be researched and analyzed to prepare for the cloud conversion of the Nuclear Export and Import Control System (NEPS) operated by the Export and Import Control Office of the Korea Institute of Nuclear Nonproliferation and Control (KINAC). The Cloud Computing Act defines cloud computing, establishes a basic plan and implementation plan, provides support for promoting the adoption of cloud computing by state institutions, supports the construction of integrated information and communication facilities based on cloud computing technology, provides cost and technical support, and regulates cloud security certification, and applies the Personal Information Protection Act and the Act on Promotion of Information and Communication Network Utilization and Information Protection to protect personal information. The E-Government Act defines integrated standards and principles for information resources, support for the use of cloud computing services, classification standards for information resources, and integrated standards for calculating the size and capacity of information systems. The Notice on Standards for Using Cloud Computing Services and Securing Safety for Administrative Agencies and Public Institutions specifies the standards for using cloud computing services and measures to secure stability for administrative agencies, contracts for using cloud computing services, and ensuring continuity of cloud computing services. The Basic Guidelines on National Information Security stipulate the establishment and implementation of security measures, system security, user security, security management, information and communication network security separating internal network and internet network, and cloud computing security measures, and stipulate the NIS security review when introducing private cloud services. In order to convert NEPS to the cloud computing services, network, and software design plans, transfer plans, and cloud operation plans will be established in compliance with the relevant laws and guidelines. And future research will include researching the system status of major public and private cloud service providers and analyzing their advantages and disadvantages.

The Internal Compliance Program (ICP) is a framework for promoting compliance with laws and regulations and minimizing violations. It aims to prevent law breaches, by raising awareness of the compliance within the organization, which leads to enhance the credibility of the organization, and to prepare for audits. From the perspective of nuclear export control, ICP can be used to verify the company’s credibility by following NSG Guidelines and is expected to contribute to preventing the vertical and horizontal proliferation of nuclear weapons in the international community. However, ICP system is not globally established, and the NSG does not provide official guidelines for ICP. Therefore, this study aims to analyze the “Good Practices for Internal Compliance Programs for Nuclear and Nuclear-Related Exports” provided by the Pacific Northwest National Laboratory to find ways to apply and activate ICPs for domestic exporters. The form of ICP could vary depending on company’s size and internal environments, but it should be organized as follows. First, an internal department should be established so as to implement the ICP, and an executive who has export control knowledge should be assigned as the Chief Export Control Officer (CECO). The CECO, establish and revise ICP operating procedures and manual, organize contact point to communicate internally and externally. Second, measures should be established minimize risks in the export process, including business development transaction screening, supply chain, research and development, human resource, and intangible technology transfer risks. Third, internal control system should be established for export control compliance. The CECO should conduct regular assessments to ensure compliance and strengthen the organization’s internal export compliance processes. Fourth, an export-related training program should be periodically conducted for employees. In addition, as soon as the CECO becomes aware of, CECO should review the matter, take corrective action, and report to the relevant national authorities, when a violation of domestic export control laws or suspicious circumstances are captured. Nuclear export control plays an important role in ensuring nuclear nonproliferation. Republic of Korea has been implementing the ICP system for Dual-Use Items under the Foreign Trade Act, but not for Trigger List Items. Therefore, introduction of ICP for Trigger List Items is expected significantly contribute to nuclear nonproliferation. The subjects of ICP will be initially targeted to major nuclear enterprises, then gradually expanded to all nuclear enterprises. Further researches are needed to introduce on ICP for Trigger List Items.

In the late 80s, non-proliferation of weapons of mass destruction, including nuclear, chemical, and biological, became an internationally important issue, and in order to keep pace with the international situation, Korea amended the Foreign Trade Act in 1992 to legislate the export control of strategic goods. In addition, Korea joined the NSG, one of the international export control regimes, in 1995, and nuclear power operators are required to obtain export licenses in accordance with the NSG export control guidelines. In the nuclear export business, technical documents, equipment, materials, SW, etc. are exported to the importer, and the export items may include strategic items designated by the NSG, so operators must check whether they are strategic items and, if so, obtain an export license in accordance with foreign trade laws that reflect the NSG export control guidelines. In the case of processing and exporting goods or materials imported from another country, exporters must fulfill complex nuclear export control procedures, including obtaining the original supplier’s consent for re-transfer. In recent years, the international situation on export control has been more sensitive than ever, including the Russo-Ukrainian war, the U.S.-China semiconductor supremacy dispute, and U.S. lawsuits against domestic companies related to original technologies. In the worst-case scenario, a company may not be able to fulfill a contract due to export control issues. In order to facilitate the smooth export business of operators when exporting nuclear energy, ‘Nuclear Export Control Pre-Consulting’ is proposed to check compliance with export control requirements in advance and provide operators with customized export control implementation plans reflecting business characteristics. Through the pre-consultation, issues, requirements, and preparatory documents related to nuclear export control can be checked before the export business starts in earnest, i.e., when the decision to participate in the business is made, and the business can be supported to export smoothly by complying with the export control system. The most important aspect of pre-consultation is that domestic nuclear exporters need to know and apply for the program. To this end, the program will be actively promoted online and offline, and support will be provided for easy application through NEPS. In addition, procedures and outcomes will be continuously refined to ensure that the program is a means of ensuring full compliance with international nuclear non-proliferation norms for nuclear exports.

Under the Foreign Trade Act, an export license from the Nuclear Safety Commission is required to export items specified in Part 10 of Schedule 2 of the Public Notice of Exportation and Importation of Strategic Items (Trigger List Items). In the case of nuclear materials, deuterium, and heavy water, its cumulative amount determines whether it is trigger list item. An export license is required only if the cumulative amount exported to a single end-user country from January 1st to December 31st exceeds the regulation criteria. The reason for this cumulative control is to exclude small amounts of materials from the scope of control as they are considered less important in view of nuclear proliferation, but to prevent the possibility of acquiring large quantities of materials by importing small amounts several times. As a result, export control of nuclear material, deuterium, and heavy water requires different considerations than other Trigger List Items. First, materials exported by different companies must be consolidated to manage the cumulative amount. Second, it is necessary to continuously follow up the actual export status. If the material is not exported after it was classified as ‘non-Trigger List Items’, it should not be included in the cumulative amount. Third, there may be a difference between the accumulated quantities aggregated at the time of the classification and the time of the actual export. The classification should be changed if an export of the classified material is postponed or another export of same materials occurs before the export of the classified material. Fourth, the classification result of these materials should not be reused. Generally, the classification result could be reused within the expiration date (2 years) but in the case of substances. However, the reuse of classification result for materials should be limited as the classification results could be change depending on the cumulative amount. In addition, the sharing of classification results between different entities should also be restricted. The government approval procedures are required even for export of small amounts of nuclear materials which are less than the regulation criteria. The cumulative quantities of nuclear materials are systematically managed in the Nuclear Export & imPort control System (NEPS) through these procedures. NEPS is also linked to the custom clearance system of Korea Customs Service, which enables to track actual exports and the time of exports. However, cumulative quantities for the heavy water and deuterium are managed individually by classification reviewers. The annual export plans are received in advance from major entities which deal with the materials for nuclear uses, and the cumulative quantities for each application are managed manually. The systematic management has not been required as there were a few cases of exporting small quantities. However, systematic management may be required in the future as overseas expansion attempts from various companies in the nuclear field has been increasing. In addition, further study is needed on the criteria and system for calculating the cumulative amount. The time of aggregate the cumulative amount should be clarified by considering the difference between the time of classification and actual export. It is required to devise an efficient way to follow up the actual export.

Both ISO 21001 and ISO 9001 are standards developed by the International Organization for Standardization (ISO) for quality management systems. However, while ISO 9001 focuses on the general requirements for Quality Management Systems (QMS), ISO 21001 is specifically designed for educational institutions. ISO 9001 is a widely recognized standard for QMS applicable to almost industries, including manufacturing and services. It defines the requirements for establishing, implementing, maintaining, and continuing improvement of QMS to improve customer satisfaction by meeting customer requirements and improving overall performance. Meanwhile, ISO 21001 focuses specifically on educational institutions and is designed to develop and improve the curriculum efficiency by meeting trainees needs. It provides a system in which educational institutions can build, implement, maintain, and continuously improve the Education Management System (EMS) for the purpose of improving the satisfaction of trainees and other stakeholders. ISO 21001 covers a wide range of educational organizations, including schools, universities, and education providers. KINAC/INSA, the Center of Excellence in Korea, is an educational institution in the field of nuclear control. So It has been developed and operated various international and domestic curriculum. KINAC/INSA obtained ISO 9001 certification in November 2016 and has been certified so far. However, in the scope of ISO 9001 certification, curriculum development process is not included so KINAC/ INSA needs to obtain additional ISO certification specialized in education to improve the education quality. That is why KINAC/INSA is developing the ISO 21001 system, and aims to acquire certification in November 2023. This paper explains the necessity for educational institutions to obtain ISO 21001 in comparison with ISO 9001. It also introduces the process of developing ISO 21001 system of KINAC/INSA. By implementing EMS based on ISO 21001, KINAC/INSA can expect to improve the educational satisfaction of trainees and other stakeholders through effective curriculum development and educational operation.

An administrative agreement (AA) was signed between NSSC and UAE FANR in January 2023 under Article 5 of the ROK-UAE Nuclear Cooperation Agreement. The AA aims to enhance regulatory efficiency in safeguards and export control. This study reviewed the export control measures for the items subject to the agreement (ISA) and implementation procedures under ROK-UAE AA by comparing them with other countries cases. First of all, the ROK-UAE AA distinguishes between ISA and the inventory management target items. Technology is divided into two categories, one requiring consent for retransfer and the other, considering the characteristics of technology that is free to be copied and deleted, and thus less useful for inventory management. Only the former is included in the annual report, which differs from the ROK-Canada or ROK-Japan NCA, which includes all technologies subject to the agreements in the annual report. When ROK notifies export information, it is mandatory to specify whether the technology requires consent for retransfer. Furthermore, some technologies should be controlled as strategic information, even if excluded from the annual report, so efforts to prevent confusion are required. Secondly, the ROK-UAE AA covers all items in INFCIRC/254/rev.9/part1, unlike the ROK-U.S. and ROK-Canada NCA, which listed equipment subject to them. This is significant because it clarifies the criteria for regulation by increasing the consistency between the trigger list items in the domestic law and the ISA. However, the expanded ISA scope could result in some changes in export control procedures. For example, when importing nuclear material (NM) from the US, only uranium was controlled as ISA, and the packages were not considered. In contrast, when exporting fuel assemblies (FA) for UAE, both uranium and zirconium cladding should be treated as ISA. To this end, NEPS was improved to implement the features of the ROK-UAE AA. Consideration of the criteria and methods for imposing obligations under the agreement is essential because this is the first case of Korea concluded AA under exporting NPP and as a supplier of FA. Generally, the obligations for NM are imposed by the country of origin, conversion, and enrichment countries. Canada and EU recognize the fuel fabrication process as a substantial transformation and impose customs origin where the process takes place. Hence, NM fabricated from Canadian equipment is also subject to the same obligations as NM of Canadian origin. From this perspective, it would be appropriate to ensure ROK acts as a supplier and controls when exporting domestically manufactured FA. Moreover, a proper national obligation code system will be required to specify Korea’s control rights.

다국적기업의 쉐어드 서비스 센터가 인적자원관리 서비스를 전 세계 법인에 제공하는데 있어 중 요한 매개체가 되고 있다. 쉐어드 서비스 센터 설립을 위한 가장 중요한 의사결정이 입지 선정이며, 이는 쉐어드 서비스 센터의 설립 동기를 이해하기 위해서는 필수적이라 할 수 있다. 그러나 이와 관련된 연구는 매우 부족한 상황이다. 이에 본 연구는 행동적 관점에서 입지 선정의 동기 중에서 비용절감과 서비스 품질 외에 본사의 쉐어드 서비스 센터 통제 동기에 초점을 맞추었다. 북미, 유 럽, 아시아에 소재하는 6개의 다국적기업 사례연구 결과, 본국과 센터가 위치한 국가와의 언어의 유사성, 본사와 센터와의 지리적 근접성 및 본사와 센터와의 시차가 본사 통제의 세부 요인으로 파 악되었다. 종합하면, 본 연구는 다국적기업이 쉐어드 서비스 센터를 관리함에 있어 본사의 통제 동 기의 중요성을 강조함으로써 쉐어드 서비스 센터의 본질에 대한 새로운 통찰을 제공한 점에서 의의 를 찾을 수 있다.

In this study, to control the heading angle of a ship, which is constantly subjected to various internal and external disturbances during the voyage, an LADRC (linear active disturbance rejection control) design that focuses more on improving the disturbance removal performance was proposed. The speed rate of change of the ship’s heading angle due to the turn of the rudder angle was selected as a significant factor, and the nonlinear model of the ship’s maneuvering equation, including the steering gear, was treated as a total disturbance. It is the similar process with an LADRC design for the first-order transfer function model. At this time, the gains of the controller included in LADRC and the gains of the extended state observer were tuned to RCGAs (real-coded genetic algorithms) to minimize the integral time-weighted absolute error as an evaluation function. The simulation was performed by applying the proposed GA-LADRC controller to the heading angle control of the Mariner class vessel. In particular, it was confirmed that the proposed controller satisfactorily maintains and follows the set course even when the disturbances such as nonlinearity, modelling error, uncertainty and noise of the measurement sensor are considered.

Purpose: This study aimed to understand the in-depth experiences of infection control liaison staff (ICLS) in hospitals. Methods: This qualitative study applied Colaizzi’s phenomenological research method and targeted 12 healthcare workers in various occupations with experience as ICLS in the departments of a general tertiary hospital in Seoul and a general hospital in Gyeonggi-do. Data were collected through individual in-depth interviews from February 21, 2022, to April 30, 2022, and data analysis was conducted in a circular structure based on Colaizzi’s phenomenological research method. Results: A total of 32 themes and 14 theme clusters were derived from 132 meaningful statements, resulting in six categories. The six categories are “A prepared mind to infection control”, “The initial burden weighing on one’s shoulders”, “Facing difficulties due to inadequate work support”, “Overcoming with cooperation and rewarding”, “The transformed patient and work environment in my journey of personal growth”, and “Finding support measures for ICLS”. Conclusion: The results of this study are, expected to help understand the meaning and value of ICLS in medical institution departments. Based on this, it will be possible to contribute to preparing primary interventions for education and capacity development, support measures, and system improvement for infection control personnel in medical institution departments.

Background: Despite the fact that aquatic exercise is one of the most popular alternative treatment methods for children with cerebral palsy (CP), there are few research regarding its effectiveness. Objects: The purpose of this study was to examine the effects of aquatic exercise on upper extremity function and postural control during reaching in children with CP. Methods: Ten participants (eight males and two females; 4–10 years; Gross Motor Function Classification System levels II–IV) with spastic diplegia were recruited to this study. The aquatic exercise program consisted of four modified movements that were selected from the Halliwick 10-point program to enhance upper extremity and trunk movements. The participants attended treatment two times a week for 6 weeks, averaging 35 minutes each session. The Box and Block Test (BBT), transferring pennies in the Bruininks-Oseretsky Test (BOT), and pediatric reaching test (PRT) scores were used as clinical measures. Three-dimensional motion analysis system was used to collect and analyze kinematic data. Differences in BBT and BOT values among pre-treatment, post-treatment, and retention (after 3 weeks) were analyzed using a Friedman test. In addition, the PRT scores and variables (movement time, hand velocity, straightness ratio, and number of movement units) from the three-dimensional motion analysis were tested using a Wilcoxon signed-rank test. The significance level was established at p < 0.05. When the results appeared to be statistically significant, a post-hoc test for multiple comparisons was performed with the Wilcoxon signed-rank test. Results: All clinical measures, which included BBT, transferring pennies of BOT, and PRT, were significantly increased between pre-intervention and post-intervention scores and between pre-intervention and retention scores after treatment (p = 0.001). Three-dimensional motion analysis mostly were significantly improved after treatment (p = 0.001). Conclusion: Aquatic exercise may help to improve body function, activity, and participation in children with varying types of physical disabilities.

In this study, the safety aspects were studied by comparing the charge control characteristics of the two vehicles when a failure occurs between the OBC including the charging port or the charging door module (CDM) during slow charging using the In Cable Control Box (ICCB) for a long time.When the AC terminal was momentarily disconnected during charging, the Model-3 vehicle was charged normally if the AC circuit was disconnected up to three times, and the charging control was stopped when the number of disconnects reached four times. However, in the Ioniq-5 vehicle, charging control was normally performed when the disconnected AC circuit was normally connected regardless of the number of disconnection.

The emergence of micropollutants in natural water sources due to the overuse of anthropogenic chemicals in industry and households has threatened the production of clean and safe tap water in drinking water treatment plants. Conventional physicochemical processes such as coagulation/flocculation followed by sand filtration are not effective for the control of micropollutants, whereas chemical oxidation processes (applying chlorine, permanganate, ozone, etc.) are known to be promising alternatives. Determining the optimum oxidant dose is important issue related to the production of disinfection by-products as well as unnecessary operating cost, and is made possible by simulations of target-micropollutant abatement based on kinetic model equation consisting of second-order rate constant (between the oxidant and the target) and oxidant exposure. However, the difficulty in determining oxidant exposure as a function of complex water quality parameters limits the field application of kinetic model equation. With respect to representative oxidants used in drinking water treatment plants, this article reviews two main approaches for determining oxidant exposure: i) direct measurement in situ and ii) prediction by empirical models based on key water quality parameters. In addition, we discussed research requirements to improve the predictive accuracy of the empirical models for oxidant exposure and to develop a rational algorithm to determine optimal oxidant dose by considering the priority of the target pollutants to be treated.
