Marine microalgal biotoxins can accumulate in seafoods, posing significant risk to human health. These toxins include tetrodotoxin (TTX) and can cause paralytic shellfish poisoning (PSP), diarrhetic shellfish poisoning (DSP), and amnesic shellfish poisoning (ASP). With accelerating climate change, the frequency and intensity of harmful algal blooms capable of producing biotoxins have increased. In South Korea, the Ministry of Food and Drug Safety (MFDS) regulates traditional toxins, including TTX and toxins causing PSP, DSP, and ASP. In contrast, the U.S. Food and Drug Administration (FDA) and European Food Safety Authority (EFSA) have established regulatory standards for a broader spectrum of marine biotoxins, including yessotoxins (YTXs), brevetoxins (BTXs), azaspiracids (AZAs), and ciguatoxins (CTXs), to ensure seafood safety. To effectively address this global concern, the MFDS launched an R&D project entitled "Establishment of the Safety Management System for Marine Biotoxins" (2020–2024). This project focused on enhancing analytical methods to detect unregulated toxins, assessing contamination levels, and developing rapid detection techniques. The project proposal emphasizes the need to establish a comprehensive monitoring system to mitigate future risks, particularly as climate change expands the range of toxic marine species. This project aims to advance our understanding of marine biotoxin contamination and strengthen seafood safety measures in South Korea by aligning them with international standards. This special issue compiles knowledge accumulated and technical advancements related to marine biotoxins, stemming from the outcomes of this project. It includes 12 papers describing analyses of various regulated and unregulated marine biotoxins, the current prevalence of seafood contamination, toxicity assessments, rapid analytical methods, and the state of safety management.

The current inspection count for imported grains is 37,072. The scientific management of stored grain, which includes methodical pest identification and control procedures, is highly prioritized in the nations that export these grains. International documents on stored grain pests include a thorough description of all life phases, including mites and larvae, as well as methodical treatment techniques. They are more valuable than domestic manuals because of their comprehensive coverage and methodical management strategies. There is lack of genetic resources and photographs since the identification of stored grain pests in the domestic have been based on data from before 2017. During the course of 13 years(2010-2022) 1,469 incidences of stored grain pests were detected. Of these, 7 orders 34 families and 81 species had cases where the identification was confirmed down to the species level, for a total of 963 cases. This number shows that about 18% of the domestic quarantine site’s stored grain pests are not species-identified. Objectives in this study are to present genetic barcode data, high-resolution photoes for classification and identification, and information on international stored grain pest management techniques. Building on this, a new identification manuals for stored grain pests might be created, which would improve the site’s taxonomic identification levels.

전 세계적으로 농업해충의 약제 저항성 발달에 따른 방제 효율 저하는 농약의 과다 사용을 초래하여 농업의 생산성 저하 및 환경 파괴 문제 등을 야기하고 있다. 뿐만 아니라 위생해충의 경우에도 약제 저항성 발달이 심각한 수준으로 나타남에 따라 인류 보건에 큰 위협이 되고 있다. 해충의 약제 저항성은 자연계에 존재하는 극히 낮은 빈도의 저항성 형질이 반복적인 약제 사용에 따라 선발되는 과정을 통해 발달 되는데, 해충 약제 저항성의 효과적 관리를 위해서는 저항성 발달 기작의 규명과 신속·정확한 진단법의 확립이 필수적이다. 현재까지의 저항성 관리 는 저항성 발달 후 대응적(reactive)으로 이루어져 왔으나, 미래에는 보다 다양한 분자 마커를 활용하여 저항성 형질 빈도를 관리 가능한 수준에서 유지하는 선제적(proactive) 저항성 관리도 가능할 것으로 예상하고 있다. 본 발표에서는 해충 약제 저항성 연구의 현재 상황과 미래 전망에 대해 소개하고자 한다.

목적 : 본 연구는 8세에서 19세의 근시 학생을 대상으로 어린이 근시관리 누진 안경렌즈의 착용실태를 조사하고 착용 후 2년간 근시도의 변화를 확인하고자 하였다. 방법 : 2019년 6월부터 2023년 5월까지 수원 G 안경원에서 어린이 근시관리 누진렌즈를 구매한 110명을 대상 으로 근시 진행완화를 위해 렌즈의 착용을 지속하고 있는지 그리고 중도 포기했다면 그 이유를 조사하였다. 그 후 2차 정기방문으로 안경을 다시 교정받은 기록이 있는 72명을 대상으로 초점렌즈(A그룹, 33명)와 어린이 근시관리 누진렌즈(B그룹, 39명)를 착용한 두 그룹으로 나누어 2년간 추적 조사하였다. 결과 : 어린이 근시관리 누진렌즈를 처방받은 110명의 1차 대상자 중 15명(13.6%)이 근시진행 완화 안경 착용 을 중도 포기했으며 이들 중 남자는 11명(73.3%), 여자는 4명(26.6%) 이었다. 또한, 중도 포기한 이유로는 구매의 편의성과 비용문제가 주된 이유로 조사되었다. 1차, 2차, 3차 방문 시기에 평균 등가구면 굴절력은 A그룹에서는 – 2.09±1.43, –2.78±1.52, –3.31±1.55 D이었고, B그룹은 –2.04±1.08, –2.63±1.06, -2.94±1.08 D로 측정되 었다. 각각의 안경을 2년간 착용한 후에 평균 등가구면 굴절력의 변화량은 A그룹에서 –1.22±0.56 D이었고, B그 룹에서는 –0.90±0.51 D를 보였다(p=0.010). 결론 : 8세에서 19세의 근시가 있는 초중고 학생은 2년 간 어린이 근시관리 누진렌즈를 착용한 후에 단초점렌즈 를 착용한 그룹에 비해 근시 진행이 지연되었다. 근시관리 안경렌즈의 성공적인 시장 정착을 위해서는 더욱 다양한 모집단을 장기 추적 관찰하여 그 효과를 연구한 자료가 필요하다고 생각된다.

The current survey form of grassland has not played its role in managing the grassland effectively because of the ambiguous questionnaire items and the absence of method and time of the investigation. Therefore, this study was conducted to clarify and add the items for effective of grassland management. The survey form of grassland was regulated in Article 16 of the Enforcement Rules of the Grassland Act (Survey on Grasslands Management Status, etc.). The five contents that needed improvement were the grassland owner, the survey timing and method of established grassland, grassland used livestock, grassland usage condition, and grassland grade. In the improved survey form of grassland, the grassland owner was changed to the grassland manager. In addition, ‘Survey by each land’ was added to the improved survey form in which the managers can survey each land. The dimension of each grassland establishment method was deleted in the grassland establishment time and method. In the livestock using grassland, the number of livestock and the area where livestock are used were added, and the number of other livestock was added, too. The grassland grade was decided as the combined score by three evaluation categories; grassland usage, the ratio of forage production in grassland and kinds of forage. The high, middle, and low grades were over 8, 6~7, and under 5 points in the combined score, respectively. The results show that the changed survey form of grassland can make grassland management more efficient by materializing the subject of grassland management and the survey terminology and methods.

The Varroa mite, Varroa destructor is an ectoparasite that parasitizes honey bees. The widespread usage of acaricides, particularly fluvalinate, has resulted in the emergence of resistance in Varroa mite populations all over the world. The goal of this study is to track fluvalinate resistance in Varroa mite field populations in Korea using both bioassay and molecular markers. To accomplish this, a residual contact vial (RCV) bioassay for on-site resistance monitoring was developed. Early mortality evaluation in the RCV bioassay was effective for reliably separating mites with the knockdown resistance (kdr) genotype, but late mortality evaluation was useful for distinguishing mites with additional resistance factors. The RCV bioassay of 14 field mite populations collected in 2021 revealed potential resistance development in four populations. Quantitative sequencing was used as an alternate method to examine the frequency of the L925I/M mutation in the voltage-gated sodium channel (vgsc), which is related with the fluvalinate kdr phenotype. While the mutation was not present in Varroa mite populations in 2020, it appeared in 2021, rose in frequency in 2022, and was practically ubiquitous across the country by 2023. This recent emergence and rapid spread of fluvalinate resistance within a span of three years demonstrate the Varroa mite's significant potential for developing resistance. This situation emphasizes the critical necessity to replace fluvalinate with alternate acaricides, such as fenpyroximate, coumaphos, and amitraz. A few novel vgsc mutations potentially involved in resistance were identified. Potential factors driving the rapid expansion of resistance were further discussed.

음악 예술경영을 연구하는 것은 음악 전공의 발전에 매우 중 요한 의미가 있다. 음악과 예술은 상호 보완적이면서 불가분한 관계이다. 음악 예술경영의 모델과 방법은 음악 예술의 발전함 에 따라 끊임없이 발전하고 혁신하고 있다. 음악 예술경영은 지속성과 복잡성의 특성을 지닌 통합적이고 체계적인 프로젝트 이다. 현재 학문 간의 합병과 동질화 발전 추세에 따라 대학 음악 경영 인력의 양성 방식도 변화가 시급히 필요하며, 음악 예술을 다양한 문화, 학문 등과 결합시켜야 한다. 그러나 현재 중국 대학 등 고등 교육 기관은 사회 발전 방향 에 발맞춰 교사 인력 및 커리큘럼을 설정하는 데 여전히 문제 가 존재한다. 따라서 대학에서 양성한 음악 예술경영 인재는 현대 관리 및 네트워크 운영 등 측면에서의 종합 능력이 부족 한 것으로 보인다. 대학의 음악 예술경영 전공의 인재 양성은 어려움을 직면하고 있다. 따라서 사회와 음악 시장의 발전을 적용하기 위해 대학은 음악 경영 인재의 양성 목표, 방법 및 교육 전략을 조정해야 하며 학제적인 능력을 갖추면서 시장 수 요에 부합한 인재를 양성해야 한다. 본 연구는 중국 음악 예술 경영 전공의 발전 추세를 분석하고 정리하며 중국 음악 및 예 술경영 인재 양성을 위한 제안을 제공하는 것을 목적으로 한 다.

Around the 1980s, with government’s promotion and dissemination policies for FRP (Fiberglass Reinforced Plastics) of the government as a main material of fishing boats, approximately 97% of the entire fishing boats in Korea have utilized FRP until now. Nevertheless, diverse social and environmental issues have emerged due to the susceptibility to fire and the generation of substances detrimental to human health during the construction process of FRP fishing vessels. Especially, the high disposal cost and the limitation of recycling technology in the disposal process of FRP fishing boats have elicited attention to circular economy. This research intended to grasp the management status and problems of disposed FRP fishing boats in Korea, and to assess the level of competitive advantage of FRP fishing boats’ recycling technologies of FRP fishing boats based on VRIO (Value, Rarity, Imitability, Organization) analysis through domestic and foreign management policies and related recycling examples. According to the survey of 161 respondents, including the industry, stakeholders and experts related to the collection, treatment and recycling of fisheries wastes, it was revealed that FRP fishing boats’ recycling technologies of FRP fishing boats are at the level of ‘unused competitive advantage’ that satisfied the level of value, rarity and imitability, but not the level of organization.

Japan’s government has announced plan to release the contaminated water stored from the tanks of the Fukushima Daiichi nuclear power plant site into the sea in June. The contaminated water is treated by SARRY (Cesium removal facility) and ALPS (advanced liquid processing system) to remove 62 radionuclide containing Cesium, Strontium, Iodine, and so on using filtration, precipitation (or coprecipitation) and adsorption for other nuclides (except for H-3 and C-14). The total amount of the contaminated water stored at tanks is 1,328,508 m3 (as of March 23, 2023). Currently, three ALPS systems which are existing ALPS, improved ALPS, high performance ALPS have been operated to meet the regulatory standard for release to the sea. According to the release plan, they have announced that 30 nuclides and H-3 concentration of the contaminated water will be measured and assessed before/after the discharge of the contaminated water into the sea. Before the release, the contaminated water is re-treated by reverse osmosis membrane facility and additional ALPS. And then, the water will be diluted with seawater more than 100 times. The diluted water will then move through an undersea tunnel and be released about 1 kilometer off the coast.

In recent years, there is rising conversation about animal welfare with increasing concern about animals. However, disease control is still not being carried out effectively. It is hard to discuss the specific plan of the domestic animal shelter and pet shop due to limited information about their present condition. Thus, we analyzed existing data and suggested a new disease control system. Disease management reports of pet shops and animal shelters investigated by local government and animal protection organizations were the main reference of this study. As the euthanasia rate of shelters has recently decreased, animals stay in shelters for extended periods. As a result, mortality rate from disease has increased. Also, many animals in pet shops die due to health problems. In animal shelters, there is always a certain proportion of individuals with disease, and many shelters do not treat them or vaccinate animals before infection. In pet shops, information such as each individual’s health condition and vaccination records is not properly disclosed, and contagious pathogens are detected in hygiene tests. In order to improve the condition, each animals’ information should be dealt with using a system based on ICT technology. Also, it is necessary to perform antibody tests and infectious disease kit tests provided by local governments, set up breeding environment manuals, and supervise the management of local governments.

The livestock industry continues to grow around the world, but livestock odor is becoming an environmental problem that is difficult to solve. In this review paper, the current status of the domestic livestock industry, livestock odor complaints, mediation cases involving environmental disputes related to livestock odor, livestock odor management policies and standards, livestock odor sources, major odor compounds, and emission characteristics are summarized. Domestic meat supply and meat consumption per capita are increasing, and livestock farms are becoming large-scale and intensive. Livestock odor complaints increased 4.5 times over the last five years (2014-2019), and its proportion to total odor complaints was 19%-30%. Livestock facilities larger than a certain size are classified as odor emission facilities and are managed based on the Odor Prevention Act. The information presented in this paper can be used to establish strategies to promote the sustainable development of the livestock industry while resolving air quality deterioration and public health problems caused by odor emissions from livestock farms.

Recently, Japan’s government has announced Tokyo Electric Power Company’s plan to discharge contaminated water stored from the tanks of the Fukushima Daiichi nuclear power plant site into the sea. The contaminated water is treated by advanced liquid processing system (ALPS) to remove 62 radionuclide containing cesium, strontium, iodine and etc. using co-precipitation (or precipitation) and adsorption for other nuclides (except for tritium and carbon-14). The total amount of the contaminated water generated by ALPS facility is 1,311,736 m3 (as of August 18, 2022). The amount of contaminated water is estimated same as Tokyo dome volume. Under the sea discharge plan, the contaminated water will be diluted in seawater more than 100 times, and tritium concentration lowered 1/7 of the drinking water standard set by the World Health Organization (10,000 Bq/liters). The diluted water will then move through an undersea tunnel and be discharged about 1 kilometer off the coast.

According to the article 18 of NSSC notice “Regulations on the delivery of low-and intermediatelevel radioactive wastes”, the consignor shall establish and implement the quality assurance program about waste management to ensure conformity with the criteria set forth in the regulations and detailed criteria proposed by the disposal facility operator, including matters related to characterization of the waste concerned. To meet the above requirement, commercially available laboratory information management system, STARLIMS from Abbott Informatics was introduced in the late of 2019 and was customized to our standardized test method in 2020. In that time, Electronic Lab Notebook (ELN), which is an electronic system to create, store, retrieve, and share fully electronic records, was tailored to replace paper lab notebook. Scientific Data Management System (SDMS), which is computer system used to capture, centrally store, catalog, and manage data, was installed. Due to the parsing ability of SDMS, human error like mistake while data entry was reduced by extracting data from measurement sheet and exporting measurement data to designated area of ELN and this feature made work efficiency improved. Afterward, validation of STARLIMS was conducted following the procedure of user acceptance testing including Operational Qualification and Performance Qualification. As a result of these activities, STARLIMS has been officially operated and applied to means to manage test results since 2021. In 2021, for user-friendly environment, updating STARLIMS was also conducted by applying SDMS to import data from other radiometric measurements including gas proportional counter (GPC), liquid scintillation counter (LSC), and low-energy Ge detector (LEGe) besides HPGe detector for gamma measurement. From implementation to operation, it is confirmed that STARLIMS has been providing reliable and stable platforms to manage laboratory information regarding measurement records and playing a significant role in tool to meet the quality assurance required.
