우리나라의 “곤충산업의 육성 및 지원에 관한 법률”은 곤충산업에 대한 직면한 문제 등 다양한 관점에서 다루 고 있다는 점을 시사한다. 이는 곤충에 대한 연구를 인간과 함께 할 수 있는 식용화, 약리활성 접근법을 통해 변화 를 가져야 한다는 것을 의미하기도 한다. 최근의 시사점은 곤충을 식용화하여 곤충산업을 활성화 하는 것이 최우 선 과제로 이 역시 곤충에 대한 혐오가 가장 큰 문제였다. 예를 들면, 곤충은 생리활성물질을 포함하고 있어 기능성 식품으로 개발되었지만 곤충에 대한 인식전환의 문제점을 내포하고 있다. 곤충을 활용할 때 가장 큰 장점은 유기 성 폐자원을 분해할 수 있기 때문에 우수한 곤충자원을 확보하는 하는 것이 우리의 연구에서 매우 중요하다. 따라서 본 연구에서는 대표적인 곤충인 굼벵이 유충을 성장단계에 따라 유기성 폐자원을 분해할 수 있는지를 평가했다. 우리의 연구에서 굼벵이 유충은환경정화곤충으로서의 가치는 감소가 되었다. 또한 이 결과는 곤충농 가의 활용 측면에서 기초적 정보를 제공하는데 있다.

Over four years (2020–2023), 305 traps were strategically placed across South Korea to collect data on Vespidae species. Our findings showed that Vespula flaviceps, Vespa crabro, and Vespula koreensis were the most frequently encountered species. Vespa velutina was also widespread, suggesting its successful integration into local ecosystems. The ARL analysis, using the “apriori” algorithm, identified significant co-occurrence patterns and potential interactions. The rules generated indicated both competitive and coexistent relationships with varying levels of association strength across different regions. Clustering analyses, including hierarchical and k-means clustering, grouped species based on their occurrence similarities. The distinct clusters formed in the analysis highlighted the unique ecological roles and interactions of V. velutina and other Vespidae species in South Korean ecosystems.

Q fever is a highly infectious tick-borne zoonotic disease caused by Coxiella burnetii, a major pathogen that can cause reproductive disorders in ruminants such as cattle. Being one of the livestock infectious diseases with uncelar causative factors and transmission routes, there is a high possibility of transmission between wildlife, disease vectors, and livestock. Despite extensive research due to its high infectivity and significant economic losses, much of the focus has been on aspects such as pathogen detection, immunodiagnosis, and veterinary medicine. However, understanding the ecological interaction between the vector (ticks) and reservoir hosts (rodents) is crucial for elucidation the transmission dynamics to livestock. In this presentation, we aim to discuss genetic variation analysis approaches and ecological co-occcurrence analysis to understand the transmission pathways between rodents, ticks, and cow.

전국적으로 매년 말벌 벌집 신고수는 약 20만건이 넘으며 부상자는 1-2만명, 사망자도 10-15명씩 나타나고 있다. 이에 따라 매년 소방청에서는 여름과 가을에 벌 쏘임 사고 ‘주의보’를 발령하고, 벌 쏘임 사고 예방에 대한 주의를 요하고 있다. 이처럼 말벌은 강력한 독침을 가진 사회성 곤충으로 외부 천적으로부터 그들의 군집을 지키 기 위한 방어행동이 매우 잘 발달되어 있다. 말벌은 외부의 인위적인 자극에 대해 천적의 침입으로 인식하고 집단 공격을 하는데 주로 검은색과 같은 짙은색의 긴털을 가진 대상에 대해 강한 공격성을 보였으며, 초록색, 노란색과 같은 자연색에는 크게 반응하지 않았다. 집단 공격시 약 10-15m 정도까지 추적하면서 공격을 하였고 천적이 벌집으로부터 약 3m 이내에 들어오면 경계 비행 후 공격하였다. 따라서 말벌 위험 지역에서는 이러한 특성을 잘 파악하여 행동하는 것이 말벌의 피해를 줄이는 방법이다. 또한 말벌의 독성 강도는 장수말벌의 독이 가장 강했으며 그 뒤로 꿀벌, 좀말벌, 털보말벌, 등검은말벌, 말벌, 왕바다리 순으로 나타났다.

곤충 생물다양성의 파괴는 결국 인류의 몰락을 가져올 정도로 심각하지만, 생물다양성을 지키는 것이 그리 간단하지만은 않은 것 같다. 벌목의 곤충은 잎을 섭식하는 식식성부터 숙주의 개체수를 조절해주는 기생성과 집단으로 생활하며 먹이를 공급받는 사회성에 이르기까지 다양한 습성을 갖는 분류군이다. 뿐만아니라 나비목, 딱정벌레목, 파리목, 노린재목과 같이 다양성이 매우 높은 5대 분류군 중 하나이다. 2021년 발간된 한국곤충명집 에 따르면 현재 우리나라 벌목의 곤충은 67과 1,137속 4,223종으로 알려져 있다. 국내 분류학 전문가들의 꾸준한 연구 노력의 결과 우리나라 벌목 뿐만아니라 곤충의 분포 정보는 해마다 늘어가고 있으나, 생물다양성의 손실은 세계 곳곳에서 가시화되고 있다. 국내에 서식하는 다양한 벌목 곤충들이 앞으로도 이곳을 떠나지 않고 우리와 함께 하기를 바라며 이번 심포지움이 국내 곤충다양성 유지를 위한 작은 움직임이 되길 바란다.

Mongolian herders rely significantly on grazing their animals, such as goats, sheep, cattle, horses, yaks, and camels, in broad rangelands throughout the year. The availability of appropriate forage, the amount of hay and forage to be kept, and whether the animals will acquire physical strength from the pasture to make it through the impending cold season are all determined by the meteorological conditions of the year. Herders' principal source of income is animals, therefore preventing mortality is a top priority. In Mongolia, meadows are a major element determining cattle live weight. However, in the summer of 2022, Mongolia faced a drought, which resulted in inadequate pastures and starved cattle. Livestock might lose weight in these situations due to a lack of supplemental feeding.

The chemical composition of 86 species of native plants in Korea, including plants to be afforestation, was analyzed. The chemical composition of the species analyzed was different. The species with the highest extractable content was Viburnum dilatatum (3.91%), and the species with the lowest extractable content was Ligustrum lucidum (0.11%). The lignin content ranged from 12 to 39%, with an average of 25%. The species with the highest lignin content was Chaenomeles lagenaria (39.37%). Hemicellulose content ranged from 18 to 52%, with the highest species being Thuja occidentalis (51.22%) and Eucommia ulmoides (48.84%). Cellulose content ranged from 25 to 58%, and the species with the highest content were Prunus serrulata (57.67%), Diospyros kaki (57.14%), Aesculus turbinata (53.29%), Albizia julibrissin (53.02%), and Zelkova serrata (52.29%). The chemical composition was different for each use taxon of 86 plant species. The lignin content was the highest in the fruit group and the lowest in the group other than recommended species for afforestation. Cellulose content was highest in non-reforestation-recommended tree species and lowest in fruit trees. In classification according to tree height, lignin content was higher in shrubs than in tall trees, and cellulose content was highest in tall trees. Between deciduous and evergreen trees, the lignin content was high in deciduous trees (26.46%), and the cellulose content was also high in deciduous trees (44.01%). As a result of analyzing the correlation between each compound, there was a difference. There tended to be a positive correlation between extractives and lignin content. There was a negative correlation between extractives and holocellulose content, hemicellulose and cellulose. The higher extract content affected the cellulose content much more than hemicellulose. Also, the higher the lignin content, the lower the cellulose content. The species with low lignin content and high cellulose content were Diospyros kaki and Prunus serrulata var. spontanea. This result is expected to be primary data for bioenergy, pulp industry and bioindustry.

Background: Children with cerebral palsy face challenges in maintaining body stability because of structural and functional defects. Their ability for responsive balance control is diminished. While there exist various trunk stabilization exercises such as Kinetic Link training (KLT) and the Bird-dog posture, there is a notable dearth of research that applies KLT specifically to children with cerebral palsy. Objectives: To investigate the effects of KLT and Bird-dog exercise on gross motor function and balance in children with cerebral palsy. Design: Quaxi-experimental study. Methods: The study participants were randomly divided into two groups: 15 individuals in the KLT group and 15 in the Bird-dog group. General characteristics were examined, and initial measurements of Gross motor function measure (GMFM) and Pediatric balance scale (PBS) were taken prior to the intervention. Each group engaged in KLT exercises and Bird-dog exercises for 20 minutes, three times a week over an 8 week period. Following the completion of the 8 week intervention, secondary measurements of GMFM and PBS were conducted. Results: In the KLT group, both PBS and GMFM showed a significant increase after the intervention compared to before (P<.05). Similarly, in the Bird-dog group, both PBS and GMFM significantly increased after the intervention compared to before (P<.05). There was a significant difference observed in PBS when comparing the pre- and post-intervention changes between the two groups (P<.05), whereas no significant difference was found in GMFM between the groups when comparing the pre- and post-intervention changes (P>.05). Conclusion: The interventions involving KLT and Bird-dog exercises were observed to effectively enhance PBS and GMFM in children with cerebral palsy. Specifically, it was evident that KLT was more beneficial in improving balance abilities compared to Bird-dog exercise.

Background: Effective trunk stabilization has been a cornerstone in physiotherapy, particularly for individuals with lower back issues. While bridging exercises were traditionally employed for this purpose, there has been a growing interest in their modified versions to optimize therapeutic benefits. Objectives: To investigated the differential effects of traditional and modified bridging exercises, particularly when varying leg support and integrating abduction maneuvers during sling-assisted exercises, on trunk muscle responsiveness. Design: Cross-Sectional study. Methods: A group of twenty participants was subjected to three exercise protocols: Bilateral Limb Bridging (BLB), Single Limb Bridging (SLB), and Single Limb Bridging combined with Hip Abduction (SLBHA). Using Surface Electromyography (EMG), the study captured the activation patterns of the Internal Oblique (IO), Erector Spinae (ES), and Multifidus (MF) muscles. Statistical analysis was conducted using the Kruskal-Wallis test, with post-hoc examination for detailed insights. For data consistency, normalization was executed based on Maximum Voluntary Isometric Contractions, and EMG data interpretation was conducted using the RMS technique. Results: The most prominent variations in muscle activation were identified in the IO muscles on both sides. The left IO displayed marked activation disparities between BLB vs. SLB and SLB vs. SLBHA. Analogous observations were made for the right IO when comparing BLB to SLBHA and BLB to SLB. Conversely, ES and MF muscle activations remained consistent across the different exercises. Conclusion: Modified bridge exercises with sling-assisted leg supports with abduction can selectively activate IO muscles, with a noticeable asymmetrical effect favoring the left side.

Background: Most non-pharmacological interventions for tension-type headache (TTH) focus on direct intervention in areas associated with headaches, with limited research exploring the indirect effects of interventions utilizing the fascia. Objectives: To investigate the effects of superficial back line (SBL) stretching and head-neck massage interventions on the range of motion (ROM) and neck disability index (NDI) of TTH. Design: Randomized controlled trial. Methods: The study participants were randomly allocated into three groups: SBL stretching group (n=9), head-neck massage group (n=9), and combined group (n=9). Prior to the intervention, measurements were taken for neck flexion ROM, straight leg raising test (SLRT) ROM, and NDI. The intervention consisted of 30-minute sessions conducted twice a week for 8 weeks. The second measurement took place 4 weeks after the intervention, followed by a third measurement conducted after an additional 4 weeks of intervention. Results: Comparing neck flexion ROM within each group, a significant increase was observed in the SBL stretching group after 8 weeks compared to before the intervention (P<.05). Regarding the comparison of SLRT ROM within each group, a significant increase was noted after 8 weeks compared to before the intervention in the SBL stretching, head-neck massage, and combined groups (P<.05). In terms of the comparison of NDI within each group, a significant decrease was observed in all three group after the intervention compared to before the intervention (P<.05). Conclusion: 8-week intervention involving SBL stretching, head-neck massage, and their combined application demonstrated effectiveness in improving neck flexion ROM, SLRT ROM, and the NDI for individuals with TTH.

Background: Chronic back pain not only causes physical discomfort and decreased functionality but also affects emotional well-being, resulting in feelings of anxiety, depression, and other psychological issues. Studies have indicated that cognitive functional therapy and motor control exercises can alleviate chronic low back pain and associated psychological issues. Objectives: To investigated the effect of chronic low back pain on the cognitive functional therapy (CFT) and motor control exercises (MCE). Design: Quaxi-experimental study. Methods: Forty patients with chronic low back pain were randomly assigned and divided into 20 cognitive functional therapy group with motor control exercises group (CFTMG) and 20 patients in motor control exercises group (MCEG). After applying CFT with motor control exercises and motor control exercises for 8 weeks, changes in numeric pain rating scale (NPRS), Oswestry disability index (ODI) and Fear-avoidance beliefs questionnaire (FABQ) were observed. Results: In the CFTMG, statistically significant changes were observed in NPRS, ODI, and FABQ before and after the intervention. In the MCEG, statistically significant changes were observed in VAS and ODI before and after the intervention. Conclusion: The application of CFTM and MCE in patients suffering from chronic low back pain has demonstrated effectiveness in alleviating pain, enhancing back function, and reducing kinesiophobia associated with the condition.

The root-lesion nematode Pratylenchus spp. is the most important plantparasitic nematode due to its worldwide distribution, wide host ranges, and migratory endoparasitic characteristics. One population of Pratylenchus collected from the giant pussy willow (Salix chaenomeloides Kimura) in the Andong area as part of a nematode survey in Korea was characterized morphologically and by molecular methods. The analysis of morphological measurements and morphometric characteristics, as well as DNA sequencing of the rRNA large subunit (LSU) D2/D3 expansion segments and the internal transcribed spacer (ITS) gene sequence, confirmed the identity of this population as P. hippeastri. This study is the first report of P. hippeastri associated with Salix chaenomeloides in Korea and worldwide. Further studies on distribution and pathogenicity in different P. hippeastri host crops, such as grapevines, strawberries, and apples, are necessary. The taxonomic keys to 16 Pratylenchus species in Korea are provided.

Currently, Japan is undertaking a nationwide project to measure and map radioactive contamination around Fukushima, as part of the efforts to restore normalcy following the nuclear accident. The Japan Atomic Energy Agency (JAEA) manages the Fukushima Environmental Safety Center, located approximately 20 km north of the Fukushima Daiichi nuclear power plant in Minamisōma City, Fukushima Prefecture. In collaboration with the JAEA, this study involved conducting comparison experiments and analyses with radiation detectors in high radiation environments, a challenging task in Korean environments. Environmental radiation surveys were conducted using three types of detectors: CZT, NaI(Tl), and LaBr3(Ce), across two contaminated areas. Dose rate values were converted using dose rate conversion factors for each detector type, and dose rate maps were subsequently created and compared. The detectors yielded similar results, demonstrating their feasibility and reliability in high radiation environments. The findings of this study are expected to be a crucial reference for enhancing the verification and supplementation of procedures and methods in future radiation measurements and mobile surveys in high-radiation environments, using these three types of radiation instruments.

1976년에 제정된 미국의 외국주권면제법은 외국정부의 주권적, 공법적 행위에 대해서는 미국법원은 원칙적으로 재판관할이 없음을 표명하면서, 예외적으로 그 외 국정부의 행위가 해당 주권면제법에서 규정하는 예외(exception)에 해당할 경우, 미국법원의 외국정부에 대한 재판관할을 인정한다. 특히“테러행위 예외(terrorism exception)”규정은 1996년에 외국주권면제법에 처음으로 추가되었으며, 외국 정부가 테러행위를 지원하여, 미국의 국무부로부터 “테러지원국”으로 지정된 국가의 경우, 해당 테러행위로 인해 신체적, 정신적 손해 를 입은 피해자들은 해당 테러지원국에 대해 민사상 책임을 묻는 민사소송을 미국 법원에서 제기할 수 있다. 본 논문에서는 외국주권면제법 상의 테러행위 예외 규정과 1996년 제정 이후 개 정된 내용을 살펴보고, 법원에서 관련 내용을 어떻게 적용했는지를 검토한다. 특히 테러행위 예외규정을 해당 규정이 제정 또는 개정되기 이전의 테러행위에도 소급 적으로 적용할 수 있는지? 피해자들에게 징벌적 손해배상도 부여할 수 있는지? 또 한 미국법원에서 테러지원국의 민사상 손해배상 판결을 획득한 피해자들이 테러지 원국의 재산을 압류 또는 집행할 때의 문제점 등을 거론한 판례도 살펴본다. 추가 적으로 북한에 대해 테러행위 예외를 적용하여, 북한의 재산을 압류, 집행한 오토 웜비어(Otto Warmbier) 관련 판결, 이란의 미국 내 재산압류에 대한 미국 판결 등을 분석한다.

In this study, the impact load resulting from collision with the fuel rods of surrogate spent nuclear fuel (SNF) assemblies was measured during a rolling test based on an analysis of the data from surrogate SNF-loaded sea transportation tests. Unfortunately, during the sea transportation tests, excessive rolling motion occurred on the ship during the test, causing the assemblies to slip and collide with the canister. Hence, we designed and conducted a separate test to simulate rolling in sea transportation to determine whether such impact loads can occur under normal conditions of SNF transport, with the test conditions for the fuel assembly to slide within the basket experimentally determined. Rolling tests were conducted while varying the rolling angle and frequency to determine the angles and frequencies at which the assemblies experienced slippage. The test results show that slippage of SNF assemblies can occur at angles of approximately 14° or greater because of rolling motion, which can generate impact loads. However, this result exceeds the conditions under which a vessel can depart for coastal navigation, thus deviating from the normal conditions required for SNF transport. Consequently, it is not necessary to consider such loads when evaluating the integrity of SNFs under normal transportation conditions.

Background: The flexible flatfoot is characterized by a flattening of the foot arch due to excessive bodyweight. The use of shoe insoles or taping methods has been identified as effective in realigning the navicular or calcaneus bones and addressing supination in pronated feet. Objects: This study aimed to analyze the difference between the arch taping attachment method, introduced in a previous study, and a novel taping method designed to provide support to the inner aspect of the heel bone in cases of flexible flatfoot. Methods: A navicular drop test was performed to discriminate flexible flatfoot. To analyze the differences in pressure distribution during walking for each taping method, the subjects underwent testing in the barefoot state with no attachments. The procedure included a sequence of arch taping and heel taping. Subsequent analysis of pressure distribution during walking utilized the GaitRite® system (GAITRite Gold, CIR Systems Inc.). Results: Arch taping and calcaneus taping significantly reduced the integrated pressure over time and peak pressure on the medial side of the midfoot for both feet compared to the barefoot state. Conclusion: The findings of this study suggest that supporting the inside of the heel through calcaneus taping, without direct stimulation to the longitudinal arch and navicular bone, is an effective intervention for flexible flatfoot.

Background: Ankle sprains occur frequently among humans who undertake various body movements. Diverse walking environments and dual tasks, that can affect ankle sprains, have been studied. However, there is a lack of research on inter-trial variability according to the changes in gait speed. Objects: The purpose of this study was to compare the adaptive ability of walking between the subjects with chronic ankle instability and healthy adults while performing a walking task with different walking speeds. Methods: In this study, 24 people in the chronic ankle instability group and 24 people in the healthy ankle group were selected as subjects. The length of the pre-measurement and the actual walking measurement were both set to 4.6 m. Once the subjects entered the measurement section, they changed their gait speed according to the randomly assigned speed change. Gait was measured twice and the average value was used for the analysis. Results: The coefficient of variation (CV) of cycle time in subjects with chronic ankle instability showed a significant difference in all cases except when the subjects changed their speed from preferred to slow and from slow to preferred. The CV of step length demonstrated a significant difference in all cases except for the change from slow to preferred and from preferred to fast. The cycle time and step length differential showed a significant difference only when the subjects changed the speed from slow to fast. Conclusion: The subjects with chronic ankle instability were found to have significantly reduced walking adaptability while performing inter-trial variability tasks with different gait speeds compared to healthy subjects.

Revolutionary advancements, such as the reduction in DNA sequencing costs and genome editing, have transformed biotechnology, fostering progress in manipulating biomolecules, engineering cells, and computational biology. Agriculture and food production have significantly benefited from tools like high-throughput microarrays, accelerating the selection of desired traits. Genetic engineering, especially utilizing genome editing, facilitates precise alterations in plants and animals, harnessing microbiomes and fostering lab-grown meat production to alleviate environmental pressures. The emergence of new biotechnologies, notably genome editing, underscores the necessity for regulatory frameworks governing LM (living modified) organisms. Global regulations overseeing genetically engineered or genome-edited (GE) organisms, encompassing animals, exhibit considerable diversity. Nonetheless, prevailing international regulatory trends typically exclude genomeedited plants and animals, employing novel biotechnological techniques, from GMO/ LMO classification if they lack foreign genes and originate through natural mutations or traditional breeding programs. This comprehensive review scrutinizes ongoing risk and safety assessment cases, such as genome-edited beef cattle and fish in the USA and Japan. Furthermore, it investigates the limitations of existing regulations related to genome editing in Korea and evaluates newly proposed legislation, offering insights into the future trajectory of regulatory frameworks.

Background: Single nucleotide polymorphisms (SNPs) are widely used genetic markers with applications in human disease diagnostics, animal breeding, and evolutionary studies, but existing genotyping methods can be labor-intensive and costly. The aim of this study is to develop a simple and rapid method for identification of a single nucleotide change. Methods: A modified Polymerase Chain Reaction Amplification of Multiple Specific Alleles (PAMSA) and high resolution melt (HRM) analysis was performed to discriminate a bovine polymorphism in the NCAPG gene (rs109570900, 1326T > G). Results: The inclusion of tails in the primers enabled allele discrimination based on PCR product lengths, detected through agarose gel electrophoresis, successfully determining various genotypes, albeit with some time and labor intensity due to the use of relatively costly high-resolution agarose gels. Additionally, high-resolution melt (HRM) analysis with tailed primers effectively distinguished the GG genotype from the TT genotype in bovine muscle cell lines, offering a reliable way to distinguish SNP polymorphisms without the need for time-consuming AS-PCR. Conclusions: Our experiments demonstrated the importance of incorporating unique mismatched bases in the allele-specific primers to prevent cross-amplification by fragmented primers. This efficient and cost-effective method, as presented here, enables genotyping laboratories to analyze SNPs using standard real-time PCR.
