This study investigated the weather conditions, fine particle concentration, and ion components in PM2.5 when two cold fronts passed through Busan in succession on February 1 and 2, 2021. A analysis of the surface weather chart, AWS, and backward trajectory revealed that the first cold front passed through the Busan at 0900 LST on February 1, 2021, with the second cold front arriving at 0100 LST on February 2, 2021. According to the PM10 concentration of the KMA, the timing of the cold front passage had a close relationship with the occurrence of the highest concentration of fine particles. The transport time of the cold front from Baengnyeongdo to Mt. Gudeok was approximately 11 hours . The PM10 and PM2.5 concentrations in Busan started to increase after the first cold front had passed, and the maximum concentration occurred two hours after the second cold front passed. The SO4 2-, NO3 -, and NH4 + concentration in PM2.5 started to increase from 1100 to 1200 LST on February 1, after the first cold front passed, and peaked at 0100 LST to 0300 LST on February 2. However, the highest Ca2+ concentration was recorded 2-3 hours after the second cold front had passed.

Since the National Research and Development Innovation Act. was enacted, evaluation and management of research outputs become more important. The research output is defined as all types of information resources produced from the scientific research activities in each research phase, such as learning, proposing, performing, and publishing. Among them, research outputs mainly from the publishing phase have been systematically managed, including articles, books, technical reports, patents, and software. KINAC, like other Korean R&D institutions, has also achieved growth in research outputs, through continuously increased investment in R&D projects. However, R&D productivity, technology transfer, and commercialization remain low level. The importance of R&D performance diffusion has been emphasized. It’s because the creation of economic value through the utilization of research results has been emerging as a key issue in R&D policy. Therefore, various policies are being nationally pursued to promote the utilization of research achievements, but the results are not being effectively utilized and disseminated. In the field of nuclear nonproliferation and security, it is also difficult to diffuse the R&D performance. In this study, the research outputs of KINAC from 2010 to 2021 were analyzed. A number of research outputs have been made and managed, but the R&D performances have not been analyzed and identified yet. In addition, supportive methods were suggested for efficient performance management toward diffusion. For this purpose, some policies of Korea and other countries concerning performance diffusion -related policies were reviewed. The best practices of performance management and applications were also reviewed and compared to the KINAC cases. As a result, the number of research output has dramatically increased during the last 10 years, showing an average annual total output of 84 and year-on-year increase of 18%. The biggest change was in the conference papers and journals, whereas, there were no trends by year in the case of the technical reports and patents. Of course, it was proportional to the size of the organization, the number of research projects, and its budget. Because many studies highlight the importance of institutional resources, capabilities, and processes for performance management as factors affecting efficient diffusion, the current status of our process was also identified. This study is expected to be applied to the improvement of the performance management of the institute, leading to the enhancement of the R&D performance application.

In 2004, in order to comply with UN Security Council Resolution 1540, the European Union (EU) came into force with Regulation 428/2009 for the export control of dual-use items, which has been working to prevent the proliferation of weapons of mass destruction (WMDs). In August 2021, it amended the EU 821/2021 to include mandating the introduction of ICPs for exporters in the member countries in order to strengthen controls over the transfer of tangible and intangible technologies. The main contents are as follows; 1) Mandatory introduction of Internal Compliance Program (ICP): Exporters within the EU countries should introduce a transaction review procedure through the ICP in consideration of their size and organization. 2) Export control on Cyber Surveillance Items to protect human rights: In order to protect human rights and comply with the obligations of international human rights law, EU countries should implement export controls on cyber-monitoring items exported from customs zones in the EU. Cyber surveillance items are specially designed to monitor, extract, collect or analyze data such as biometrics through intrusion of information and communication systems or deep packet hijacking. However, items used for purely commercial programs such as billing, marketing, quality service, user satisfaction or network security are excluded. 3) Expansion of the Catch-all system: EU countries should utilize the catch-all system to strengthen export controls on cyber-monitoring items, including dual-use items. 4) Strengthening control over the cloud: Exporters and EU countries should extend the scope of intangible technology transfer, such as electronic media, fax, and telephone, outside the EU’s customs territory, and apply export control regulations such as general or comprehensive licenses to cloud transmissions outside the EU territory. 5) Introduction of large-scale project authorization: To reduce the administrative burden on enterprises (especially small and medium-sized enterprises) and authorities when exporters with individual or collective licenses export to one or more specific end-users for the purpose of large scale projects, provided that they ensure the implementation of an appropriate level of export controls; EU countries may introduce large-scale project license systems in the form of general authorization. Recently, there is a possibility that the ROK would export its nuclear technologies including APR1400 to the EU member countries in the midst of the EU adoption of carbon-zero policy. In this paper, we have analyzed the EU export control regulations and suggested the future direction of nuclear export control programs in the ROK.

Thermospheric wind observations from high to mid latitudes are compared with the newly developed Multiscale Atmosphere Geospace Environment (MAGE) model for the Nov 3–4 geomagnetic storm. The observation and simulation comparison shows a very good agreement and is better at high latitudes in general. We were able to identify a thermospheric poleward wind reduction possibly linked to a northward turning of the Interplanetary Magnetic Field (IMF) at ~22 UT on Nov 3 and an enhancement of the poleward wind to a southward turning near 10 UT on Nov 4 at high latitudes. An IMF southward turning may have led to an enhancement of equatorward winds at Boulder, Colorado near midnight. Simultaneous occurrence of aurora may be associated with an IMF By turning negative. The MAGE model wind simulations are consistent with observations in these cases. The results show the model can be a very useful tool to further study the magnetosphere and ionosphere coupling on short time scales.

Geologic disposal of high-level radioactive waste is considered the most effective method to isolate high-level radioactive waste from the biosphere. A high-level radioactive waste repository is designed to be placed at a deep depth and generally consists of canisters, buffer material, and host rock. In the disposal system, the heat from the canister occurs for millions of years due to the long half-life of the high-level radioactive waste, and the heat induces vaporization of groundwater in the buffer material. The resaturation process also occurs due to groundwater inflow from the host rock by the hydraulic head and capillarity. The saturation variation leads to the heat transfer and multi-phase flow in the buffer material, and thermal pressurization of groundwater due to the heat affects the effective stress change in the host rock. The stress change can make the porosity and permeability change in the flow system of the host rock, and the flow system affects the nuclide migration to the biosphere. Therefore, it is crucial to understand the complex thermo-hydro-mechanical-chemical (THMC) coupled behavior to secure the repository’s long-term safety. DECOVALEX is an international cooperating project to develop numerical methods and models for predicting the THMC interactions in the disposal systems through validation and comparison with test results. In Task C of DECOVALEX-2023, nine participating groups (BGR, BGE, CAS, ENSI, GRS, KAERI, LBNL, NWMO, Sandia) models the full-scale emplacement (FE) experiments at the Mont Terri underground rock laboratory and focus on understanding pore pressure development, heat transfer, thermal pressurization, vaporization and resaturation process in the disposal system. In the FE experiment, three heaters generated heat with constant power for five years at a 1:1 scale in the emplacement tunnel based on Nagra’s reference repository design. KAERI used OGS-FLAC3D for the numerical simulation, combining OpenGeoSys for TH simulation and FLAC3D for M simulation. We generated a full-scale three-dimensional numerical model with a dimension of 100 by 100 by 60 meters. The pressure and temperature distribution were well simulated with the host rock's anisotropy. Based on the capillarity, we observed vaporization and resaturation in the bentonite under the twophase flow system. We plan to compare the simulation results with the field data and investigate the effect of input parameters, including thermal conductivity and pore compressibility affecting the thermal and flow system.

기후 변화에 민감하게 반응하는 북극해는 지구 기후 변화의 흔적을 고스란히 간직하고 있으므로, 북 극해 퇴적물 연구는 지구 기후 변화를 연구하는 데 매우 중요하다. 2016년에 수행된 아라온호의 ARA07C 북 극해 탐사를 통하여 동시베리아해 연변부에서 획득한 ARA07C-St02B 중력 코어를 이용하여 퇴적학적, 광물 학적, 지화학적 특성을 연구하고 이를 이용하여 기원지를 추정하였다. 코어 퇴적물은 색, 입도와 빙운쇄설물 의 함량에 의하여 4개의 유닛으로 구분하였는데, 갈색층을 포함하는 유닛 1과 3은 회색층으로 구성된 유닛 2 와 4보다 모래와 빙운쇄설물의 함량이 다소 높다. ARA07C-St02B 코어 주변에서 연구된 ARA03B-27 코어 와 비교를 통하여 이들은 MIS (Marine Isotope Stage) 1부터 4시기에 퇴적된 것으로 여겨진다. 갈색층을 포 함하는 유닛들과 회색층으로 이루어진 유닛 사이에는 벌크 광물 조성, 점토광물 조성, 지화학 조성에서 차이 가 난다. 벌크 광물과 점토광물 특성은 조립질 퇴적물과 세립질 퇴적물 사이에 기원지가 다를 수 있음을 시 사한다. 조립질 퇴적물은 대부분 랍테프해와 동시베리아해로부터 동시베리아 연안류나 추크치해로부터 보퍼트 환류를 따라 운반된 것으로 여겨지지만, 세립질 퇴적물은 대부분 동시베리아해, 추크치해, 보퍼트해로부터 해 류에 의하여 운반된 것으로 추정된다. 유닛 1의 일부 조립질 퇴적물과 유닛 3의 세립질 퇴적물은 보퍼트해와 캐나다 북극 군도로부터 해류, 빙산 또는 해빙에 의하여 연구 지역에 퇴적된 것으로 판단된다. 잠재적인 근 원지의 지화학 조성에 관한 자료를 획득하게 되면, 연구 지역의 코어 퇴적물의 기원지와 공급 방법에 대하여 좀 더 자세하게 규명될 수 있을 것으로 판단된다.

From January 1, 2020, the International Maritime Organization has implemented a global regulation, known as IMO 2020, to reduce the sulfur content in fuel oil of ships from 3.5% to 0.5%. In this study, we used data from air monitoring stations to evaluate the change in air quality at New Port and North Port in Korea areas after the regulation was implemented. The concentration of SO2 and NO2 was higher in the port areas than in the surrounding areas due to exhaust gas from ships and vehicles. However, the SO2 concentration decreased by more than 50% in the port area, demonstrating the efficiency and positive effect of the IMO 2020 sulfur limit.

이 연구는 코로나19로 인해 원격수업과 등교수업이 병행된 2020년 2학기 중・고등학교에서 실시된 원격수업이 1학기와 비교하여 교사의 수업과 학교생활에 어떤 영향을 미쳤는지를 분석하고 보다 바람직한 원격교육 환경조성 방안을 모색하기 위한 목적으로 수행되었다. 이를 위해 2020년 1, 2학기 원격수업을 경험한 교사 총 330명(중학교 교사 166명, 고등학교 교사 164명)을 대상으로 온라인 설문조사를, 수석교사 4인을 대상으로 초점집단인터뷰(FGI)를 실시하였다. 그 결과는 다음 과 같다. 첫째, 2020년 2학기 수업활동과 관련하여 중학교 교사들이 고등학교 교사들에 비해 수업 준비를 위한 투자시간이 더 많았다고 응답하였다. 또한 1학기에 비해 2학기 원격수업에서 중등교사 모두 ‘학생참여 유도’와 ‘출결관리’에서 큰 어려움을 겪었다고 응답하였다. 둘째, 학교생활에 관련해서 중ㆍ고등학교 교사들은 소속학교의 위기 대처와 원격수업 대응에 대해 대체로 긍정적으로 인식하는 것으로 나타났다. 셋째, 원격수업 개선과 관련하여 2학기에 실시된 원격수업과 등교수업의 병행방식에 만족하는 것으로 나타났다. 그러나 보다 효과적인 원격교육을 위해서는 ‘교과목에 따른 다양한 형태의 원격수업 방식 운영’, ‘원격수업에 적합한 평가방식의 도입’ 등이 필요하다고 보고하였다. 이를 기반으로 향후 이루어질 원격교육 개선을 위한 교육적 시사점을 제안하였다.

This study evaluates the quality of surface air temperature, relative humidity, and precipitation detection observed by 22 internet of thing (IoT)-based mini-weather stations in Seoul in 2020 summer. The automatic weather station (AWS) closest to each IoT-based station is used as reference. The IoT-based observations show surface air temperature and relative humidity are about 0.2-4.0°C higher and about -1--22% lower than the AWS observations, respectively. However, they exhibit temporal variability similar to the AWS observations on both diurnal and daily time scales, with daily correlations greater than 0.90 for temperature and 0.82 for relative humidity. Given these strong linear relationships, it show that temperature and relative humidity biases can be effectively corrected by applying a simple bias correction method. For IoT-based precipitation detection, we found that precipitation conductivity value (PCV) during precipitation events is well separated from that during non-precipitation events, providing a basis for distinguishing precipitation events from non-precipitation events. When the PCV threshold is set to 250 for precipitation detection, the highest critical success index and the bias score index close to one, suitable for operational precipitation detection, are obtained. These results demonstrate that IoT-based mini-weather stations can successfully measure surface air temperature, relative humidity, and precipitation detection with appropriate bias corrections.

The purposes of this study were to classify detailed climate types over the Republic of Korea (ROK) and to delineate their climate characteristics using the new normals of 1991-2020 for 219 weather stations. Total five climate types, Cfa, Cfb, Cwa, Dwa, and Dwb were identified in ROK based on the Köppen’s climate classification criteria. Subtropical climate types, Cfa or Cwa types were broadly covered with 79.9% of 219 stations and the most of remaining stations were included in Dwa types which had a very cold winter and hot summer with wet conditions. In the Trewartha classification, four climate types were identified, one subtropical Cfa, and three temperate Doa, Dca, and Dcb types. Dcb types were found at four stations (Daegwallyeong, Taebaek, Jinburyeong, and Sabuk) in Taebak mountains indicating the extent of cool summer climate types with more stations in mountain areas. The climate characteristics by climate types only were presented the results from the Trewartha classification with the new normals and 66 ASOS stations because Köppen’s climate classification was not appropriate for ROK. The annual mean precipitation of Cfa was the greatest while Dcb the lowest among four types. The annual range was the greatest at Dca types while the smallest at Cfa due to the geographical varieties. More detailed climate types were located in ROK with 219 weather stations and the new normals (1991-2020). However, there were some limitation applying the criteria of Köppen’s and Trewartha’s climate classification to a very complex topographical region.

This research investigated the characteristics of fine particles during cold front passage in Busan, on March 19, 2020. The cold front speed was 17.4 m/s (about 63k km/hr), moving from the northwest to the southeast, and with a width of about 64 km. The backward trajectory analysis showed that a southern sea air parcel flowed into Busan before the cold front passage, carrying continental materials from China transported into Busan after cold front passage. The PM10 concentration in Busan showed a rapid increase after passing through the cold front, with PM2.5 showing a high concentration during cold front passage. The PM2.5/PM10 ratio was 0.10 - 0.30. When the cold front passed, SO4 2-, NO3 -, Ca2+, NH4 +, Na+, and K+ in PM2.5 showed a rapid increase, with SO4 2- showing the most significant increase. These results indicated that understanding the characteristics of fine particles during cold front passage in Busan could provide insight into establishing a strategy to control urban air quality.

Heatwaves can affect human health and vegetation growth and bring about energy problems and socioeconomic damages, so the analysis and prediction of the heatwave is a crucial issue under a warming climate. This paper examines the production of STCI (Standard Temperature Condition Index) using ASOS (Automated Synoptic Observing System) in-situ observation data for the period of 1979-2020, and an STCI predictability assessment with an RF (Random Forest) model using ERA5 (ECMWF Reanalysis 5) meteorological variables. The accuracy was quite high with the MAE (Mean Absolute Error) of 0.365 and the CC (Correlation Coefficient) of 0.873, which corresponded to 7% to 10% difference for the range of STCI<1.5, and to 1% to 3% difference for the range of STCI>1.5, in terms of the probability density function. Also, we produced gridded maps for the summer STCI from 1979 to 2020 by utilizing the ERA5 raster data for the RF prediction model, which enables the spatial expansion of the ASOS point-based STCI to a continuous grid nationwide. The proposed method can be applied to forecasting of STCI by adopting future meteorological or climatic datasets.

코로나 상황(Covid-19)의 장기화로 인해 현장에서 이루어지던 많은 교육과정들이 온라인 시스템을 활용한 교육으로 전환되고 있으며, 예비교사 교육과정의 필수 과정인 교육실습 역시 온라인 교육으로 시행되었다. 본 연구의 초점은 비대면 교육시대의 온라인 교육실습을 위한 실습지도교사와 예비교사의 요구를 분석하는 것이다. 이를 위해, 첫째, 2019년 충청권 교사연구회를 통해 드러난 실습지도교사와 예비교사들의 온라인 플랫폼에 요구되는 콘텐츠와 세부 기능에 대한 요구를 파악하고, 2020년 5개의 충청권 실습학교들이 실시한 온라인 교육실습의 내용을 살펴보아 현장의 요구가 어떻게 실천되었는지를 살펴보았다. 둘째, 2020년 온라인 교육실습을 경험한 각기 다른 대학교 소속 4명의 예비교사들의 경험을 살펴 기억해야 할 가치와 교육실습의 의미에 대해 고찰해보았다. 연구의 결과로서, 실습지도교사는 실습의 전 과정의 흐름을 드러내는 콘텐츠의 중요성, 학생들은 실제실습의 과정에 초점이 맞춰진 콘텐츠들의 중요성을 언급했다. 실습지도교사와 예비교사 모두 소통을 중심으로 한 온라인 교육실습의 가치를 드러냈다.

에밀리 헤일은 T. S 엘리엇에게 애인이자 친구 그리고 뮤즈였다. 이 점은 2020년 1월 2일 프린스턴 대학교에서 개봉된, 1930년도부터 1936년도의 엘리엇의 편지에서 확인되었다. 엘리엇은 헤일을 버리고 38년이나 어린 비서였던 발레리와 결혼한다. 부모와 조상의 종교였던 유니테 리언니즘으로부터 앵글로 가톨릭으로 개종한 엘리엇은 가톨릭의 교리와 신앙을 반영한 단테의 『신곡』에 나타난 가장 큰 죄인 배신을 발레리와 헤일에게 느꼈다. 엘리엇의 죄의식은 1930년도부터 1936년도 사이의 개봉된 편지에서 잘 드러나 있으며 후기 시극인 『칵테일 파티』에도 드러나 있다. 『칵테일 파티』에는 엘리엇과 비비안 그리고 헤일의 관계로 추정되는 인물들이 등장한다. 헤일로 추정되는 실리아는 비비안으로 추정 되는 라비니아에게 죄의식을 가지며, 죄를 지었다는 것은 악을 행한 것이며, 악을 행한 것은 자존심을 지키는 것과 연결된다. 자존심을 지키려 한 것은 악을 행한 것이며 어쩌면 개성을 지킨 것이기도 하다. 엘리엇 은 『칵테일 파티』에서 자신의 죄의식을 실리아를 통하여 반영했다. 실리아는 자신의 죄를 씻기 위하여 아프리카로 선교여행을 떠났고 그곳에서 살해당한다. 라일리는 실리아의 이런 행동을 정화와 구원의 길이라고 해명한다. 엘리엇은 앵글로 가톨릭의 신앙을 가졌으며 비비안과 헤일에게 깊은 죄의식을 느꼈으며 이런 죄는 기억에서 유메니데스로 그를 따라다녔다. 엘리엇은 기억으로 유전되는 죄를 끊으려 했고 자신의 죄를 정화하는 고백성사를 수행했다. 그의 의식과 기억을 끊임없이 지배 했던 헤일과 비비안에 대한 죄의식은 앵글로 가톨릭의 신앙과 믿음에서 나온 것이며, 죄의식을 극복하는 것은 『칵테일 파티』의 궁극적 주제이며 헤일에 대한 속죄였다.

본고의 목적은 일본의 2020년도 검정통과 지리 교과서가 독도를 어떻게 다루고 있는지, 2015년도 검정통과 지리 교과서와 비교했을 때 어떠한 변화가 있었는지, 그리고 그 특징이 무엇인지를 검토하는 것이다. 연구 결과, 첫째, 독도 관련 기술 분량은 2015년도 검정통과 지리 교과서와 비교했을 때 대체로 비슷한 경향이 있었다. 둘째, 독도 관련 기술 내용은 교육 출판, 일본문교출판, 도쿄 서적의 지리 교과서에서 2015년도와 비슷한 경향이었고, 제국서원의 지리 교과서에서 유일하게 독도 관련 기술이 다소 강화되었다. 셋째, 사진과 지도 등의 시각적인 자료의 사용은 2015년도와 대부분 비슷한 경향이 있었다. 넷째, 2015년도 검정통과 지리 교과서의 독도 관련 기술이 이전보다 크게 강화된 것에 비하면, 2020년도 검정통과 지리 교과서는 그렇지 않았는데, 이는 중학교 지리 교과의 성격 및 사회과 교과서의 학습 과정이 그 요인이었다.
