        국내외적으로 기후변화, 이상기상 등 다양한 요인이 新문제 병해충의 발생을 가속화하고 있으나, 반대로 국제 기구에서 2030년까지 화학농약의 사용 및 위해도를 50%로 낮출 것을 요구하고 있다(생물다양성협약 COP15. 2022.12). 따라서 화학농약을 줄이면서 효과적으로 병해충을 방제할 수 있는 대안을 찾아야 한다. 화학농약의 대안으로 생명과학에 공학적 기술개념을 도입하여 인공적으로 생명체의 구성요소·시스템을 설 계·제작·합성하는 학문분야로 합성생물학이 주목받고 있다. 코로나19 백신개발과정에 합성생물학을 활용하여 개발기간을 단축한 사례(mRNA 백신)도 있다. 미국 농업분야에서는 dsRNA를 이용한 천연식물보호제(생물농 약)의 개발은 이미 상용화 단계로 넘어서고 있다. 이에 우리나라도 합성생물학을 활용한 농약의 개발과 상용화를 지원할 수 있는 제도적 기반을 마련할 시점이다. 본 발표에서는 합성생물학 기술을 이용한 新천연식물보호제의 개발과 상용화에 필요한 등록기준 마련 필요성과 고려할 사항에 대해 다각적으로 논의하고자 한다. 현재 우리나라에서 농약은 「농약관리법」에 따라 관리되며, 유효성분으로 쓰이는 원료의 종류에 따라 화학 농약과 천연식물보호제로 구분되고 있다. 화학농약은 “화학적으로 합성한 유효성분으로 제조한 것”을 말하며, 천연식물보호제는 “살아있는 미생물 또는 자연계에서 생성된 유기화합물 및 무기화합물”을 유효성분으로 제조 한 것“을 말한다. dsRNA 농약 등록을 위해서는 dsRNA 등 합성생물학 기술을 이용한 농약이 “자연계에서 생성된 유기화학물”로 분류될 수 있는 지에 대한 검토가 필요하며, dsRNA를 활용한 농약의 등록 기준이 마련되어야 한다. 기준을 마련하기 위해서는 합성생물학 기술에 대한 정확한 이해가 선행되어야 하고, 안전성에 대한 다각적 인 검토는 물론, 사회적 합의와 공감대 형성이 이루어져야 할 것이다. 우선 가장 중요한 이슈는 역시 유전자변형생물체(이하 ”LMO“) 문제이다. 국내에서는 LMO 작물의 재배 자체 에 대한 논란이 많은 상황이라는 점과 LMO일 경우 농약으로 등록시 기준 적용에 차이가 크기 때문이다. 천연식물 보호제는 화학농약보다는 등록시 요구되는 자료가 많이 간소화되어 있지만, LMO에 해당되면 그렇지 않다. 실제 미국에서 등록된 dsRNA 농약에는 LMO에 해당되는 것과 해당되지 않는 것이 있다. 따라서 국내에서 천연식물보 호제로 등록하기 위해서는 먼저 dsRNA를 활용한 기술이 LMO에 해당되는 지 여부가 먼저 정립되어야 하고, 해당 dsRNA 원제(Technical) 또는 해당 dsRNA 제품(Item)이 LMO 기술이 적용되지 않았음을 입증할 수 있는 체계 의 정립이 필요할 것이다. 또한 국제기준과 조화의 문제를 고려해야 한다. OECD 발간 문서(ENV/CBC/MONO(2023)26, ENV/JM/MONO (2020)26)에 따르면 dsRNA 농약은 dsRNA의 변이가 인체, 환경은 물론, 표적/비표적 유기체에 어떠한 영향을 미칠수 있는지에 대한 시험이 필요하고 이는 각 국가별 규제요건에 따라 달라질 수 있다고 밝히고 있다. 국내 기준을 마련하기 위해서는 외국 사례를 정밀하게 조사분석한 후 국내 여건에 맞도록 기준을 정립해야 할 것이다. 마지막으로 새로운 기술은 항상 부작용에 대한 우려가 따르기 마련이므로 전문가에 의해 과학적 근거에 기반 한 기준안이 마련함은 물론, 해당 기준안에 대한 대국민 소통/공감을 형성하는 과정도 필요하다. dsRNA농약은 우리나라에 새로운 도전이자 기회가 일 수 있다. 농약원제 개발에 뒤처져 수입에 의존하는 산업 에서 벗어나, 세계를 선도하며 수출하는 농약산업으로 바꿔야 할 시점인 것 같다.

        국내 절화류 표준규격은 장미, 카네이션, 국화 등 17개 품 목에 대하여 고시되어 있으나 이에 대한 생산자들의 인지도 및 활용도가 낮을 뿐만 아니라, 공영도매시장별 품질등급의 결정기준이 서로 달라 표준규격 운영의 실효성도 낮은 수준이 다. 이에 본 연구에서는 국내 도매시장의 화훼류 출하 실태를 조사하고 국내 시장 환경에 적합한 절화류 표준규격 개선 방 안을 모색하고자 하였다. 지난 10년간 국내 공영도매시장에서 거래된 절화류 품목의 수는 평균 228개 품목으로 꾸준히 증 가하는 추세이며, 주요 거래품목의 종류도 해마다 변화되고 있어 현재 절화류 표준규격에 고시된 품목만으로는 빠르게 변 화하는 화훼 시장에 대응하는데 한계가 있다. 2022년 기준 20대 절화류 가운데 라넌큘러스와 루스커스를 포함한 7개 품 목의 표준규격이 고시되어 있지 않다. 따라서 주요 거래품목 들을 대상으로 표준규격 고시 품목의 확대가 필요하며 품목별 표준규격 이외에 절화류 전체에 공통적으로 적용 가능한 절화 (공통) 표준규격 제정이 필요하다. 또한 현행 화훼류 표준규격 에서 품질평가 지표가 주관적 기준에 따라 평가될 수 있는 항 목들로 구성됨에 따라 aT화훼공판장에 상장된 절화의 68.1% 가 ‘특’으로 거래되는 등 실제 품질보다 높게 평가되고 있다. 이에 절화의 무게나 줄기의 굵기 등 절화의 내적 품질을 객관 적으로 평가할 수 있는 지표를 도입하고 개화정도나 결점 등 외적 품질을 판단할 수 있는 등급도감의 도입도 필요하다. 크 기구분 역시 aT화훼공판장에 상장된 절화의 18.5%만이 ‘1급’ 으로 출하되는 등 국내 생산환경에 적합한 수준으로 설정되어 있지 못할 뿐만 아니라, 온라인 유통 확대 등 절화 유통환경의 변화에 맞춰 실제 특성값을 표기할 수 있도록 표시방법을 변 경하고 절화의 길이 이외에도 꽃의 크기, 꽃 수 등 다양한 항 목의 정보를 제공할 수 있도록 개선할 필요가 있다.

        본고에서는 한자라는 계열에서 서체라는 개념을 어떻게 분석에 이용하면 좋을지를 이시즈카 하루미치(石塚晴通)의 한자자체론(漢字字體論)을 중심으로 검토하였다. 이시즈카의 한자자체 론은 서체를 글자를 아우르는 표준으로서 상위에 둔다. 이것은 자료 연구의 장에서 탄생한 실지 적인 것임을 학설의 발전 과정을 통해 알 수 있다. 또한 이시즈카가 일컫는 서체는 실질적으로는 문자 체계로서의 차이에 가까운 측면이 있으며, 오늘날 동일한 글자에 대한 서기 방식의 차이로 인식하는 것과는 이질적이라는 점을 지적하고, 그러한 현대적인 감각에 기인하는 오독 사례를 지적하였다. 그런 다음 역사적인 서체와 인쇄 서체를 구별하여 논의할 필요가 있다는 점, 이시즈 카 한자자체론을 화용론적 문헌학 pragmaphilology (Smith, 2020)의 방법으로 자리매김할 수 있음을 논하였다.

        The National R&D Innovation Act emphasizes the improvement of the quality of R&D activities. The research institute is making efforts to improve the quality of research and effectively manage research implementation. KINAC has conducted various R&D projects regarding nuclear nonproliferation and nuclear security, and their scope and scale have been gradually more widened and increased. It consequently becomes important how to successfully manage research projects and ensure their qualification with the growth and complexity of research in KINAC. Unfortunately, no attempt was made to introduce and apply project management methodologies. Therefore, the objective of this study is to introduce project management standards and guidelines as an initial step towards improving the overall research quality of the institute. Project management is the well-organized application of knowledge and techniques to efficiently and effectively initiate, plan, control, and close projects, in order to achieve specific goals and meet success criteria. There are some guidelines regarding project management, including PMBOK (the Project Management Body of Knowledge), PRINCE2 (Projects in Controlled Environments), ISO 21500 (Guidance on Project Management), and PMP (Project Management Professionals), etc. They are international standards that consist of processes, guidelines, and best practices for project management. They provide structured processes and approaches to plan, execute, monitor, control, and complete projects. By reviewing the guidelines, the commonly important factors, including schedule, cost, quality, resources, communication, and risk management were introduced to apply to KINAC R&D project implementation. In addition to the management standards, systematic efforts are also continued to enhance the R&D qualities of the institute. These efforts include the implementation of a quality management system (ISO 9001:2015), development of an integrated research achievements management system, regulation development, and distribution of guidebooks for project managers and researchers. These efforts have been evaluated as improving the quality of the research.

        In this paper, the EMP-related standards and test methods used by the civilian and military have been introduced. The incoming EMP signal for seven military RF antennas which are the first to face EMP threats among military weapon systems have been also measured and analyzed. Overall, as the applied signal strength increased, the strength of the EMP signal entering in the antenna also showed an upward trend. The highest level of entering was observed at the peak value of the applied EMP signal, 50 kV/m. And at the peak value, all antennas received threatening signals. In particular, antennas in low frequency bands such as AM and FM were getting high voltage signals as high as thousands of volts. This means that the weapon systems linked to the antennas could suffer severe damage. Therefore, based on this paper, systematic research for EMP threat should be conducted to identify EMP vulnerabilities of major weapons systems and to devise practical protective measures.

        우리나라 식물방역법은 검역병해충으로부터 국내 농업 및 자연환경을 보호하고자 규제병해충(검역병해충, 잠정규제병해충, 규제비검역병해충) 관련 위험평가, 식물검역기술개발계획, 식물검역 절차 및 방법, 검역결과 에 따른 처분, 규제병해충 예찰 및 방제 등에 관한 다양한 법적 절차 등을 규정하고 있다. 하지만, 식물검역병해충 을 어떻게 취급하여야 할 지에 관한 내용은 없다. 따라서 식물방역법이 추구하는 목적을 달성하기 위하여서는 ① 검역병해충을 어떻게 취급하여야 할 지를 규정하여야 하며, ② 검역병해충을 취급하는 시설(검사, 연구, 운송, 보관 등) 기준을 설정하고, ③ 검역병해충 취급 시설을 인증하고, 주기적인 재인증 기준을 설정하여야 한다. 이를 위하여 먼저 식물방역법에 검역병해충 취급시설 등에 관한 규정을 신설하고, 시행령, 시행규칙에 반영한 후에 ① 검역병해충 취급요령 ② 검역병해충 취급시설 기준 ③ 검역병해충 취급시설 인증기준 등의 고시를 제정하여 야 한다. 이를 위하여 식물병해충 관련 학계의 의견 반영이 가장 중요하다.

        The present study is designed to assess the ethical-moral effectiveness of three levels of AI implementations in the hospitality industry, which include mechanical AI for transactional services (automated service), thinking AI for functional services (algorithms search), and feeling AI for hedonic services (biometric sensors) when compared to consumers’ interactions with human. AI service robots are ethically challenging in use and morally controversial in its acceptance of labor replacement in hospitality contexts. In the hospitality industry, service robots have been rapidly adopted replacing frontline human services (Park et al., 2021). Service robots refer to “system-based autonomous and adaptable interfaces that interact, communicate and deliver service to an organization’s customers” (Wirtz et al., 2018, p.909). On the one hand, the applications of artificial intelligence (AI)-based service robots are promising in this field owing to remarkable accuracy in error reduction, portion control, and cost control in service operation and delivery (Berezina et al., 2019). However, on the other hand, there has been a debate on ethical and moral principles and values regarding service robots replacing human labor (Cowls et al., 2021). Nevertheless, restaurants’ adoption of service robots seems inevitable in the current marketplace as labor shortages and rising wages have challenged them to invest in automation (Tanzi, 2021). While prior research focused on the benefits of AI-based service offerings (e.g., Cristou et al., 2023; Huang & Rust, 2021; Park et al., 2021), this study explored the extent to which AI-based service robots are accepted by consumers without rising concern about service robots replacing human labors. To this end, we adopted Huang and Rust’s framework that identifies three levels of AI applications: mechanical, thinking, and feeling AIs. Mechanical AIs refer to the automation of repetitive and routine tasks (e.g., self-service technologies); thinking AIs facilitate rational decision-making based on data processing (e.g., conversational intelligent systems such as Siri); feeling AIs are able to interact with human emotions (e.g., humanlike robots that respond to human emotions such as Sophia). Further, we adopted the construal level theory (Trope & Liberman, 2003) to examine how different levels of AIs’ service capabilities influence the way that people think about AI-based service robots. In brief, this study demonstrated how different levels of AI benefits influence consumers’ moral concerns about AI-based service robotization’s replacement of human labor and social acceptance.

        The Smart AtoN(Aids to Navigation) project aims to upgrade the facilities of AtoN to provide new additional information to nearby ships and unmanned ships. This paper deals with methods for collecting various sensor data through standardized interfaces; the NMEA-0183(serial line), the NMEA-2000(CAN), and the NMEA OneNet(IPv6). The AIS(Automatic Identification System) and the AIS-ASM(Application Specific Message) are considered as communication means for providing sensor information to nearby ships. In this paper, we summarize existing NMEA sentences for collecting sensor data and AIS-ASM messages that can be used to deliver sensor data to ships. Information provided from the smart AtoN through AIS, ASM, etc. may be presented on the shipborne displays that complies with the IEC62288:2021 standard.

        Natural radionuclides-containing substances (NORM) contain natural radionuclides and cause radiation exposure. In Korea, safety management measures were needed to deal with and dispose of radon mattresses containing monazite in relation to such NORM. However, there is no clear safety management system related to NORM waste in Korea. In order to manage this reasonably and systematically, it is necessary to investigate and analyze standards and management measures related to the treatment and disposal of NORM waste. Therefore, this study investigated and analyzed the exemption and clearance level of NORM waste regulations in international organizations and foreign countries. IAEA GSR Part 3, 2013/59/Euratom, ANSI/HPS N13.53, CRCPD SSRCR Part N, and ARPANSA Publications 15 safety management regulations were analyzed to investigate safety management standards for NORM waste. The exemption and clearance level in international organizations and foreign countries were compared and analyzed based on radioactive concentration and dose. In addition, the management measures proposed for each literature were also investigated. As a result of the analysis, IAEA GSR Part 3 applied 1 mSv as a regulatory exemption level, 1 Bq/g for uranium and thorium series as a clearance level, and 10 Bq/g for K-40 nuclides. The IAEA recommends a differential approach to the potential and scale of exposure. The EU applied 1 Bq/g to uranium and thorium families and 10 Bq/g to K-40 nuclides for both regulatory exemption and clearance levels. The EU recommended that it be managed in proportion to the scale and likelihood of exposure as a result of the action. It is analyzed that this is similar to the IAEA’s management plan. In the United States, there was no single federal government radioactive concentration and dose for NORM management. The management plan differed in management status and level from state to state, and K-40 was excluded from regulation unless it was intentionally enriched. In the case of Australia, the radioactive concentration of uranium and thorium was 1 Bq/g as a standard for regulatory exemption and 1 mSv as a dose. As a management plan, it was suggested to dispose of waste by means of accumulation, dilution/dispersion, and reclamation. It was also suggested that the scale of exposure, like international organizations, take into account the possibility. The results of this study are believed to be used as basic data for presenting domestic NORM waste treatment and disposal methods in the future.

        The types of waste generated in radiation controlled areas of nuclear facilities are very diverse. Among them, the waste containing hazardous materials such as electrical equipment and fire safety equipment that do not directly handle radioactive materials is also primarily classified as radioactive waste because it was used and stored in the radiation controlled area. Such wastes include periodic consumables such as fluorescent lamps, fire extinguishers, batteries, and gas containers after use. The waste is ambiguous and cannot be easily treated as radioactive waste or waste subject to clearance, and has been stored in a radiation controlled area for a long time, and the amount is continuously increasing. The storage space is saturated and has difficulty in management. IAEA ISO-7503-2016 clearly states that surface contamination measurement can be applied to surface contamination substrates (impermeable, non-activated) instead of volume contamination measurement. In order to solve these concerns, some facilities within the Korea Atomic Energy Research Institute were selected to explore self-disposal methods based on surface contamination in consideration of the characteristics of waste and facility contamination. The surface contamination degree and qualitative gamma spectroscopic analysis were carried out by the method. First, we examined the characteristics of the facility, the history of the air pollution level of the usage/storage space, and periodic inspection records. Second, we measured the physical properties (area/weight) of the waste in the same treatment way as the existing waste. Third, gamma dose rate and surface contamination (direct/indirect method) are measured for the entire area to confirm contamination is possible. It was confirmed that the concentration standard was satisfied. In order to clarify the presence of contamination, a qualitative method of gamma nuclide analysis was also performed. All surveys/measurements of 4 types of waste at 7 facilities were performed and it was confirmed that all waste satisfies the permissible concentration standard for clearance which conservatively set at 0.1 Bq/g as the permissible concentration standard. In the future, We hope that you will use this as a reference to search for easier disposal methods for regulatory bodies and specified waste disposal methods, and contribute to reducing the amount of radioactive waste generated.

        Since the National R&D Innovation Act was enacted in 2022, it became a crucial issue how to qualify or improve R&D activities and disseminate their outcomes. Many organizations have referred to various quality management standards such as the American National Standards Institute/American Society for Quality (ANSI/ASQ) Z1.13, International Organization for Standardization (ISO) 9001, and the American Society of Mechanical Engineers Nuclear Quality Assurance-1 (ASME NQA-1), as a means to set up their own quality system. ISO is the international standard for implementing a quality management system (QMS), which provides a framework and principles for managing an organization’s QMS, with the aim of ensuring that the organization consistently provide products or services that meet regulatory requirements. ISO 9001 can cover all aspects of an organization’s operations, and it can also be expanded to include R&D areas. The introduction of ISO 9001 to R&D aims to improve R&D practices and establish a standardized process framework for conducting R&D. ANSI/ASQ Z1.13 provides quality guidelines for research and consists of 10 sections covering various aspects of research quality, emphasizing ethical conduct, clear objectives, reliable data collection, and analysis. ASME NQA-1 is one of quality assurance standards for nuclear facility applications, but it has been extended and applied to R&D activities in the nuclear fields. It just focuses on planning, procedures, documentation, competence, equipment, and material control. KINAC has conducted extensive research on verifying and regulating nuclear activities while providing support for national nonproliferation technologies and policies. In addition to the quantitative growth achieved so far, efforts are being made to establish a qualitative and integrated management system. As a first step to achieve this goal, this study reviewed international standards and methodologies for research quality and derived the key components for R&D quality management. Moreover, the appropriate outline of quality management system framework was proposed for R&D as a regulatory support process, based on the ISO 9001. The implementation of quality management standards and procedures for R&D in KINAC, which could lead to improved research practices, more reliable data collection and analysis and increased efficiency in conducting R&D activities.

        A bilateral Nuclear Cooperation Agreement (NCA) should define what is subject to the agreement and when. Nuclear Materials (NM) are the subject of NCA with almost all countries, and the definition used in these agreements is borrowed from Article 20 of the IAEA Charter. The IAEA’s definition of NM as consisting of special fissionable material and source material and describes the types of material each contains. In order to control the export of NM under national laws and implement NCA, not only the types of NM but also quantitative criteria are required. This is because controlling small quantities of NM is impossible, unnecessary, and would create excessive administrative burdens. For this reason, the NSG guidelines establish a quantitative threshold of NM requiring control. Nevertheless, no quantitative thresholds have been agreed upon for NM subject to a NCA. Whether NM transferred is subject to the NCA is primarily a matter for the supplier states to determine. The supplier states make the decision based on quantitative criteria defined in their own export control laws. ROK identifies NM that require export licenses by reflecting the same criteria as the NSG guidelines in Foreign Trade Laws and its Notifications. Less than 500 kg of Natural Uranium, 1,000 kg of Depleted Uranium, 1,000 kg of Thorium, and 50 effective grams of special fissionable materials do not require an export license and is therefore not subject to NCA. In the US, the quantitative threshold for requiring an export license is different from that of ROK. For example, special fissionable materials that are not Pu are required if the individual shipment exceed 1 effective gram or 100 effective grams per year. The difference in the quantitative thresholds for NM between the two countries mean that the same item may be subject to NCA under US standards, but not under ROK’s. For example, the export of 8 grams of highly enriched uranium (93%) contained in a neutron detector would not be subject to the NCA in ROK, but would be considered NM subject to a NCA and required a special license in the US. Of course, in order to ensure the application of safeguards and physical protection to all NM transferred between the two countries, the agreement may not include a quantitative threshold for NM. However, the absence of such a threshold can lead to different conclusions by the two countries on the same item and make it challenging to control retransfers. The definition of quantitative standards will be necessary in the supplementary administrative arrangement for the practical control and management of NM subject to the NCA.

        PURPOSES : In this paper, problems and improvements in pavement marking standards are proposed as a result of the analysis of domestic/foreign standards and field data. METHODS : In this study, the US FHWA and all state standards were analyzed and domestic pavement marking standards were compared and analyzed. In addition, national highway marking test data, namely the Yeoncheon Test-Bed data, and data from Hawkins et al. (2015) were analyzed. Based on this, problems and improvements in the Korean pavement marking standards are proposed. RESULTS : As a result of literature and field data analysis, various problems were found in the Road Traffic Act and National Police Agency manual. In this standard, there is no definition of Qd; the RD reference value is set too low; and the RW and RR reference values are difficult to be considered reasonable values. CONCLUSIONS : There is an aspect in which the standard items and values of pavement markings are set under some policy judgment. Therefore, it is necessary to properly revise the standards, considering technical and economic aspects.
