이 논문은 시진핑 집권 이후 중국이 직면한 대북 딜레마를 분석하고, 북한에 대한 새로운 접근 방식을 제시하는 것을 목적으로 한다. 중국과 북한의 관계는 흔히 혈맹관계로 인식되지만, 중국은 이를 부인하고 전통 적 우호관계로 규정한다. 시진핑 집권 초기 중국은 북핵문제와 북한문제 를 동일시 하였고, 북한의 무력도발로 인해 북중관계는 악화되었다. 그러 나 2018년 이후 중국은 북핵 문제와 북한 문제를 분리하여 접근하기 시 작하였고, 북중관계는 다시 회복된다. 중국은 주변외교를 강화하는 한편 북한을 운명공동체로 규정함으로써 새로운 형태의 관계를 구축하고자 한 다. 특히 운명공동체는 ‘풍우동주’ 및 ‘휴척여공’의 개념으로 이는 정치, 경제, 사회, 문화 영역 외에 군사 영역까지 포함하는 매우 적극적인 관계 의 형태이다. 중국의 대북 딜레마는 여전히 존재하고, 북한의 정치상황과 미중관계의 변화가 지속하는 상황에서 중국의 대북 접근법에 대해 새로 운 관점이 필요하다.

최근 가로수, 공원 등에 수목이 많이 식재되어 우리 생활 주변에 녹지가 조성되고 있었고, 이를 생활권 수목 또는 도시숲으로 불리다. 이러한 생활권 수목의 증가로 따른 현상으로, 대상 수목을 가해하는 해충 또한 증가하였 다. 생활권 해충에 대한 방제 수단으로는 농약 살포, 나무 주사 등의 화학적 방제법이 있으나, 생활권 주변이라는 특성으로 인하여 농약 살포나 나무주사 등은 바람직한 방제 수단으로 여기기 어렵다. 이에, 친환경적인 방제 방법중의 하나인 페로몬을 이용한 교미교란제법이 하나의 대안으로 판단되어 수목 해충 중 나비목 해충에 대한 교미교란제의 적용해 보았다. 대상 수목과 해충으로는 무궁화-큰붉은잎밤나방, 동백나무-차독나방, 왕벚나무- 복숭아유리나방으로, 잎을 가해하는 해충 2종과, 천공성 해충 1종을 선택하였다. 큰붉은잎밤나방은 무궁화의 가장 큰 식엽성 해충이다. 차독나방은 남부지역 동백나무에 발생하는 식엽성 해충으로, 접촉시 피부염을 일으켜 일부 관광지에서 문제가 되고 있다. 복숭아유리나방은 줄기를 가해하는 천공성 해충으로, 화학방제가 어려운 해충이다. 본 발표에서는 큰붉은잎밤나방, 차독나방, 복숭아유리나방의 교미교란제를 이용한 방제 효과와 방제 효과 평가법에 대하여 발표하고자 한다.

The current study is designed to investigate the use of deductive and inductive grammar teaching approaches in online instructional videos in a fully online asynchronous learning context across four different grammar lessons. More specifically, the study aimed to analyze two aspects about these two options for grammar instruction; their impacts on effectiveness in learning the grammar, and also the students’ perceptions of the two options in terms of interest, effectiveness, and difficulty. To address these research aims, this study employed a quasi-experimental approach where 82 participants were divided into two groups, and each group was taught via only deductive instruction or only inductive instruction. As for the results, regarding effectiveness, an ANCOVA test resulted in no differences when comparing across all four lessons combined. Furthermore, Mann-Whitney U tests indicated no difference in effectiveness for each individual grammar lesson. Regarding student perceptions, ANOVA tests indicated no difference in the students’ perceptions of interest, effectiveness, or difficulty.

Radioactive iodine released from nuclear power plants has been recognized to pose significant risks and environmental hazards. In response to these challenges, extensive investigations into iodine sorbents have been conducted with a particular focus on the utilization of layered double hydroxides (LDH) as a promising candidate. Herein, we have focused on the investigation of LDH materials featuring diverse transition metals for their synthesis, with specific emphasis on CoAl LDH for its proficiency in removing iodine species, particularly IO3 –. Nevertheless, a comprehensive understanding of the removal mechanisms employed by these LDH materials remained elusive. Hence, the primary aim of this study is to elucidate the intricacies of the removal mechanisms through sorption tests, spectroscopic techniques, and theoretical chemistry analyses, subsequently contrasting the experimental outcomes with computational results. For the experimental facet, the synthesis of CoAl LDH was conducted utilizing 0.15 mol L−1 of Co(NO3)2⋅6H2O and 0.06 mol L−1 of Al(NO3)3⋅9H2O to attain a molar ratio (M2+:M3+) of 2.5:1. Subsequently, pH-dependent IO3 – sorption tests were carried out, coupled with X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) spectroscopy, facilitating the elucidation and discourse of the removal mechanism. The theoretical chemistry in this research harnessed ab initio molecular dynamics (AIMD) simulations for structural modeling, atomic density profiles, radial distribution function, analysis of oxide species, and MD-EXAFS spectrum analysis. In summary, this study aims to elucidate iodine removal mechanisms using diverse experimental results, culminating in the revelation that ion-exchange with NO3 – present in the interlayer predominates as the principal mechanism for IO3 – removal. Notably, a distinct spectral feature at approximately 33,190 eV emerged, defying identification through XANES and EXAFS analyses conducted under experimental conditions. In the AIMD simulations, meticulous scrutiny of individual iodine atoms uncovered the prevalence of I−O and I−O−H molecular species, marked by interactions between O and H atoms, with a coordination number of I−O = ~3. This transformation was primarily instigated by proton hopping. As a result, the comparative investigation reveals the dominance of IO3 – intercalation in the CoAl LDH material with the potential to undergo a transformation to the I−O−H molecule upon interaction with protons.

Every engineering decision in radioactive waste management should be based on both technical and economic considerations. Especially, the management of low-level radioactive waste (LLW) is more critical on economic concerns, due to its long-term and continuous nature, which emphasizes the importance of economic analysis. In this study, economic factors for LLW management were discussed with appropriate engineering applications. Two major factors that should be taken into account when assessing economic expectations are the accuracy of the results and its proper balancing with ALARA philosophy (As Low As Reasonably Achievable). The accuracy of the results depends on the correct application of alternatives within a realistic framework of waste processing. This is because the LLW management process involves variables such as component type, physical dimensions, and the monetary value at the processing date. Two commonly used alternatives are the simplified lump sum present worth and levelized annual cost methods, which are based on annual and capital costs. However, these discussions on alternatives not only pertain to the time series value of operational costs but also to future technical advancements, which are crucial for engineers. As new research results on LLW treatment emerge, proper consideration and adoption should be given to technical cost management. As safety is the core value of the entire nuclear industry, the ALARA philosophy should also be considered in the cost management of LLW. The typical cost of exposure in man-rem has ranged from $1,000 to $20,000 over the past decades. However, with increasing concerns about health and international political threats, the cost of man-rem should be subject to stricter criteria, even the balancing of costs and safety concerns is much controverse issue. Throughout the study, the importance of incorporating proper engineering insights into the assessment of technical value for the financial management of LLW was discussed. However, it’s essential to remember that financial management should not be solely assessed based on the size of expenses but rather by evaluating the current financial status, the value of money at the time, and anticipated future costs, considering the specific context and timeframe.

This paper describes the development and operation of an autonomous robotic system designed for pyroprocess automation. The unique challenges of pyroprocess automation, such as the need for a highly dry atmosphere to handle materials like chloride, are addressed through this system. For the experiments, a specialized dehumidifier and dry mock-up facility were designed to produce dry air condition. Performances of dry air conditioning for the various simulated situations were evaluated, including assessing worker access within a mock-up to determine the system’s feasibility. To enable automation, containers used for processing materials were modified to fit the gripper system of the gantry robot. The loading and unloading of materials in each equipment were automated to connect them with the robotic system. This gantry robot primarily utilized macro motions to approach waypoints containing process materials, reducing the need for precise approach motions. Its tapered jaw design allowed it to grip target objects even with imperfect positioning. The robot’s motions were programmed initially using a robot simulator for positioning and motion planning, and real-world accuracy was tested in a dry mock-up facility using the OPC platform. Finally, the paper discusses the potential application of XR (eXtended Reality) technology in this context, which could enhance the robot’s operation and provide valuable insights into the automation process. Further analysis of XR technology’s feasibility and benefits for this specific pyroprocess automation system are presented.

This study tests the influence of multi-visual dimensions and textual features of electronic word-of-mouth (EWOM) on its perceived helpfulness on a sample from Saudi Arabia. This investigation is conducted in the context of Twitter through an online factorial experiment. The design incorporates a 3 (visual inclusion to text: with product-only photo, with product and face photo, without product photo) × 3 (EWOM valence: positive, positive and negative, and negative) between-subjects experiment (n = 540). It is concluded that when evaluating EWOM helpfulness, pictures do in fact contribute substantial value. For females, this effect is more pronounced when the EWOM is two-sided at the product-only photo level, and when EWOM is negative at the product with a face photo level. Thus, this study adds to the body of existing theories by arguing that EWOM helpfulness largely depends on how the textual and visual features of EWOM are communicated.

To prove the long-term safety of deep geological repository, the safety assessment is needed to ensure that the expected performance of repository satisfies the regulatory standards. Scenario development is process of analyzing events and evolutions that can directly or indirectly affect the performance of a disposal system and is a pre-step for quantitative safety assessment. Scenarios are used to identify and define cases to be assessed by numerical modeling, and cases are mainly divided into normal (also called the ‘reference’ and ‘expected evolution’) and abnormal scenarios. Mainly two approaches have been used to set up scenarios. One is a bottom-up approach that starts with features, events and processes (FEPs). This approach can analyze the evolution and events related to the performance of the disposal system in an inductive manner. The other is top-down approach that analyzes the events and evolution of disposal system, focusing on situations that may affect the safety function of the components. This approach starts with a set of intuitively predefined expected failures of safety function. Combining the two approaches is more effective in demonstrating comprehensiveness which is a main challenge of scenario analysis, and almost national radioactive waste management institutions combine top-down and bottom-up approaches for development of scenarios. An approach combining the two approaches is called a hybrid approach, and the detailed method differs from each institution and has not been determined. In this study, some work for constructing the scenario using hybrid approach was performed. Firstly, defining each component’s safety function and screening FEPs according to several rules were performed for a generic repository. Secondly, we extracted performance factors that are considered likely to affect safety functions. And lastly, we integrated FEPs correlated with performance factor to simplify the analysis. These results will be material to construct the scenario using hybrid approach.

Diabetic encephalopathy is a major complication with cognitive impairment and neurodegeneration in patients with type 1 or type 2 diabetes mellitus (DM). DM-induced glucolipotoxicity is a risk factor for Alzheimer’s disease–like phenotype, including amyloidogenesis, tau hyperphosphorylation, and neuronal apoptosis. Although the detailed mechanism underlying the pathogenesis of diabetic encephalopathy remains unclear, mitochondrial oxidative stress is emerging as a key factor for diabetic complications and neurodegeneration. A deeper understanding of the regulatory mechanism of mitochondrial oxidative stress under hyperglycemic conditions will provide insights into the development of therapeutic strategies for diabetic encephalopathy. Here, we review the role of mitochondrial oxidative stress in diabetic encephalopathy and the regulatory mechanisms by which high glucose induces the generation of mitochondrial reactive species oxygen species in neuronal cells. This review also summarizes the mitochondrial-dependent and -independent pathways (O-linked-N-acetylglucosaminylation, calcium, and glycogen synthase kinase 3β signaling) that regulate mitochondrial oxidative stress in a DM model.

EU BSSD (2013/59/EURATOM) requires that NORM involving activities are managed within the same regulatory framework as other practices causing exposure to ionizing radiation, and a graded approach to regulatory control needs to be applied based on radiation risk. The graded approach is applied to all sources of radiation subject to regulation. However, it should be adopted for industrial activities involving NORM. In the case of the regulatory control of NORM, the application of the concepts of exemption and clearance plays a key role. Most of the European countries have adopted the new EU BSSD general exemption/clearance levels, 1 Bq/g for U/Th series and 10 Bq/g for K-40. In addition to the general exemption or clearance criteria, some countries have implemented the graded regulatory approach, adopting more restrictive criteria as a specific exemption or clearance based on the risk of 1 mSv/y for workers and 0.01-0.3 mSv/y for public.

The purpose of this study is to examine the relationships between citations and the research trends of The Research Journal of the Costume Culture (RJCC) using bibliometric and network analyses. The results are as follows. First, the RJCC has been cited by a greater number of journals and high-reputation journals today. The RJCC has been mentioned in global academic journals in various fields, and it has been noted the most in environmental science. Second, because of examining the articles published in the RJCC over the past three years (2019–2021), it was found that the number of topics was evenly distributed in various subfields of the clothing and textiles sector. The RJCC principally deals with traditional clothing, ethics and sustainability, and technology, which means that the RJCC reflects the past, present, and future. As a result of conducting a cluster analysis using the Wakita-Tsurumi algorithm, the subjects of ethical fashion and sustainability were derived from the subdivisions of the RJCC. This suggests that the RJCC is a journal specialized in ethical fashion and sustainability sectors such as environmental, animal, and labor ethics. This study outlined the current status and future direction of academic journals in the field of clothing through an analysis of the RJCC’s influence change and the relationship between citations. In addition, it is academically significant because it identifies research trends and knowledge-structure changes in the apparel science field by identifying changes in research keywords and significant research topics by sector.
