        Hymenoptera is one of the most important pollinators for many crops and wild plants in Korea. Many species visit in flowers for acquirement energy source of adults, and especially bees need pollen for rearing larvae. So, bees forage on flowers more than other insects. In 2023, specice number of bees in Korea is 308 species under 6 families, 38genera. However, many bees as like bumblebees are reduced rapidly because of climate change to warm, habitat destruction as like urbanization and pestcide abuse as like Neonicotinate. For example, in Gwangreung forests there were 6 species records : Bombus ignitus, B. ardens, B. koreanus, B. ussuriensis, B. atripes and B. opulantus. But, in 2023 we could find only two species Bombus ignitus and B. ardens. Bees need protection of Habitat, healthe, and food plants by human.

        The study of blowfly (Diptera, Calliphoridae) biodiversity and distribution is crucial for forensic investigations involving cadavers. Abiotic and biotic factors, such as seasonality and habitat type, have significant impacts on blowfly populations. However, few forensic entomology studies have been conducted in South Korea, particularly the Gyeongsangnam-do region. To address this, in this study, an extensive year-long survey was conducted to analyze the compositions, habitat preferences, distribution, and seasonal abundance of forensically relevant blowflies in urban and forested habitats in Gyeongsangnam-do, utilizing mouse carcass-baited traps set for 48 h each month. A total of 3,478 adult blowflies were recorded, encompassing six genera and 14 species, with a noted absence of specimens during the winter months. The predominant species was Lucilia porphyrina, accounting for 37.1% of the total sample, followed by Chrysomya pinguis (27.5%), Lucilia sericata (7.6%), and Lucilia illustris (7.1%). The species composition was consistent across all surveyed regions; however, seasonal variation in species diversity was evident, with a peak in spring and decline in summer. Notably, certain species exhibited clear preferences for either urban (Calliphora calliphoroides and L. sericata) or forested habitats (L. porphyrina and Ch. pinguis). This pioneering study elucidates the diverse blowfly communities in Gyeongsangnam-do, highlighting significant seasonal and habitat-dependent variations.

        Kori unit 1 and Wolsong unit 1 were permanently shut down in 2017 and 2019, respectively. Both plants were decided to demolish the building without reuse. Large structures must be demolished after removing systems and components in the building, and in the case of large structures, thorough planning is required because of the large scale of work. Therefore, in this study, important considerations in the phase of the demolition plan of large structures when decommissioning were analyzed. The demolition of large structures at nuclear facilities is major one phase of work within a broader decommissioning plan. Furthermore, the actual demolition of the structure (i.e., physical process) represents the last step in a process that begins with extensive planning and analysis. The National Demolition Association (NDA) has provided checklist items that should be considered before the start of a commercial demolition project and/or in the bid process. Important Considerations in the Phase of the demolition plan of large structures when decommissioning of nuclear facilities are Site knowledge and programs, Engineering survey/demolition plan, Hazardous and radioactive materials, Open air demolition, Financial and project management, Permits, Code adherence, and Special programs, Disposal pathway, Final site condition. The results of this study can be used as a basis for the Planning large structures demolition of the Kori unit 1 and Wolsong unit 1.

        Antimicrobials in human medicine are classified by The World Health Organization (WHO) into three groups: critically important antimicrobials (CIA), highly important antimicrobials (HIA), and important antimicrobials (IA). CIA are antibiotic classes that satisfy two main criteria: that they are the sole or the only available limited therapeutic option to effectively treat severe bacterial infections in humans (Criterion 1), and infections where bacteria are transmitted to humans from non-human sources or have the potential to acquire resistance genes from non-human sources (Criterion 2). WHO emphasizes the need for cautious and responsible use of the CIA to mitigate risk and safeguard human health. Specific antimicrobials within the CIA with a high priority for management are reclassified as “highest priority critically important antimicrobials (HP-CIA)” and include the 3rd generation of cephalosporins and the next generation of macrolides, quinolones, glycopeptides, and polymyxins. The CIA list is the scientific basis for risk assessment and risk management policies that warrant using antimicrobials to reduce antimicrobial resistance in several countries. In addition, the CIA list ensures food safety in the food industry, including for the popular food chain companies McDonald's and KFC. The continuous update of the CIA list reflects the advancement in research and emerging future challenges. Thus, active and deliberate evaluation of antimicrobial resistance and the construction of a list that reflects the specific circumstances of a country are essential to safeguarding food security.

        The rapid digital transformation and the ever-changing needs of consumers have provided both academia and practice a stimulating setting and chance for grasping evolving opportunities and reinventing the traditional marketing approaches. Agility is one emergent approach to manage challenges like increasing uncertainty or high volatility. Due to its relative novelty, the extant academic literature on marketing agility is narrow, and although the operationalization of the construct is slowly expanding, there is yet the need for further refinement of the definition, the construct, terminology, and its dimensions. Similarly, in practitioner circles there is a growing “buzz” about implementing agile practices (e.g., continuous feedback-learning cycles, collaboration, flexibility, and speed) in the field of marketing to manage changing market environments. What exactly makes an organization, a department, or a team agile is, however, still blurred.

        The purpose of this study was to explore the potential of agricultural heritage as a sustainable agricultural and rural paradigm with a focus on the “Argan-based agro-sylvo-pastoral system in the area of Ait Souab-Ait Mansour”, a Globally Important Agricultural Heritage Systems (GIAHS) site in Morocco. Based on the inscription criteria of the GIAHS, we analyzed the economic-industrial, sociocultural, and ecological-environmental perspectives and presented strategies for revitalizing agricultural and rural development cooperation through the Moroccan Argan GIAHS. The argan tree has been a source of economic, cultural, and environmental stability for the Berber people for centuries, but today it is exposed to many threats. In particular, the declining consumption of argan oil by Berbers, the lack of financial independence of women's cooperatives, and the over-exploitation of the tree suggest that it is time to balance the three pillars of environmental, economic, and social sustainability that development has sought to achieve. Agricultural heritage can be preserved when local people take ownership of their heritage and utilize it to generate economic activities. Only a symbiotic way of life between humans and agricultural heritage can overcome the possibilities and limitations of the ecological environment and generate local value through the accumulation of knowledge, technology, and culture. Only on these premises, can local self-sustaining development based on the pluralistic values and public functions of the world's important agricultural heritage be possible.

        Various diffusion experiments using geologic media have been carried out and it is often assumed that aqueous diffusion is the dominant transport mechanism. However, in some cases diffusive migration has been much faster than predicted in the model simulation. To explain such results surface diffusion of sorbing species was invoked. Experimental results were generally open to interpretation but possible existence of surface diffusion, whereby sorbed radionuclides could potentially migrate at much enhanced rates, necessitated investigation. The potential for surface diffusion of some sorbing nuclides on through-diffusion experiments using domestic rocks was examined. The apparent diffusion coefficients for sorbing cations were determined from their steady-state diffusion flux through rocks disks, while effective and pore diffusion coefficients were obtained with non-sorbing tracers through the same rocks. Diffusive transport models through domestic granites and granodiorites based only on pore diffusion did not often described adequately for sorbing cations. Thus, surface diffusion should be considered. Then what was the most important measure to estimate surface diffusion? As far as we examine, the sorption reversibility provides a hint of surface diffusion. The reversible sorbing species, for example, Sr, has a remarkable surface diffusion contribution, whereas surface diffusion has a relatively small contribution for irreversibly sorbing species such as Cs and Am under domestic experimental conditions.

        Large earthquakes with (MW > ~ 6) result in ground shaking, surface ruptures, and permanent deformation with displacement. The earthquakes would damage important facilities and infrastructure such as large industrial establishments, nuclear power plants, and waste disposal sites. In particular, earthquake ruptures associated with large earthquakes can affect geological and engineered barriers such as deep geological repositories that are used for storing hazardous radioactive wastes. Earthquake-driven faults and surface ruptures exhibit various fault zone structural characteristics such as direction of earthquake propagation and rupture and asymmetric displacement patterns. Therefore, estimating the respect distances and hazardous areas has been challenging. We propose that considering multiple parameters, such as fault types, distribution, scale, activity, linkage patterns, damage zones, and respect distances, enable accurate identification of the sites for deep geological repositories and important facilities. This information would enable earthquake hazard assessment and lower earthquakeresulted hazards in potential earthquake-prone areas.

        Ornamental chrysanthemum (Dendranthema × grandiflorum Ramat.) belongs to genus Chrysanthemum in the Asteraceae (Compositae) family and is a top leading ornamental plant worldwide. During the last two decades, advances in biotechnology (genetic engineering) and nucleotide sequencing techniques have enabled a deep understanding of biological processes of many ornamental plants at a molecular level. The blue-colored chrysanthemum has been generated and commercialized, and various DNA markers were developed using advanced techniques. Ornamental chrysanthemums are hexaploidy (2n = 2x = 54) and self-incompatible, making it challenging to generate a pure line as breeding resources and a model platform for chrysanthemum research. However, recently, self-compatible pure lines of chrysanthemum (C. seticuspe) were developed, and whole-genome sequencing datasets have been open to the public. Other datasets of whole-genome sequences and transcriptome have been elucidated from wild chrysanthemums, C. nankingense and C. morifolium. In this review, recent progress in the study of ornamental chrysanthemums and the potentiality and importance of wild chrysanthemums as bioresources for ornamental chrysanthemum studies and breeding resources is discussed briefly. Many important resources for studying chrysanthemums are now available and easily accessible. Comprehensive studies with important resources will shed light on chrysanthemum research and breeding of ornamental chrysanthemums at a molecular level. Additionally, this review provides comprehensive information and should pave the way for successful research on ornamental chrysanthemums.
