        This study aimed to address the increasing demand for technologies preventing mushroom fly damage. By monitoring the annual occurrence patterns of pests over several years and accumulating data, we conducted an analysis to evaluate the efficacy of preventive measures applied before the surge in mushroom fly infestation, typically observed in May. For preemptive control, physical measures involved installing air curtains at cultivation facility entrances and placing sticky traps and insect traps around entry points to block external entry and reduce internal insect density. Additionally, we applied an organic agricultural material, Dalmatian chrysanthemum extract, weekly alongside chemical control measures. To assess the reduction in mushroom fly populations, yellow sticky traps (15×25 cm) were placed at three locations within the mushroom cultivation facility, and the occurrence patterns before and after implementing preventive measures were compared. Compared to conventional practices, the application of preventive techniques resulted in a significant reduction, with a 60% decrease from 15 levels of mushroom flies/m² to 6 levels of mushroom flies/m² in May and a 40% decrease from 10 levels of mushroom flies/m² to 6 levels of mushroom flies/m² in June. While achieving over 50% efficacy during the peak mushroom fly season with preventive measures, we identified complementary actions such as blocking external sources (gaps in cultivation facility doors) and maintaining cleanliness around cultivation facilities (proper disposal of spent substrate) for further improvement. Comprehensive analysis and safety studies, including correlation analysis with contaminants and pathogens, are recommended to ensure the widespread adoption of mushroom fly preventive techniques for safe and stable mushroom production in the agricultural sector.

        Since 1990s, despite the strong opposition of the international community, North Korea has frequently conducted nuclear weapons tests and missile tests, and the DPRK nuclear issue has become an important factor affecting the security and stability of the Asia-Pacific region. As an extremely important multilateral organization in the Asia-Pacific region, ASEAN has gradually increased its influence in the Asia-Pacific region with the advancement of integration in recent years. In order to further enhance its influence and enhance its participation in Asia-Pacific affairs, ASEAN has been trying to give its voice on the Korean nuclear issue. The ASEAN Regional Forum and ASEAN Summit are the most important platforms for ASEAN to express its position and views. Since the North Korean nuclear issue became prominent, the North Korean nuclear issue has been a key topic discussed in the ASEAN Regional Forum and ASEAN Summit. Judging from the conference documents produced by the conferences over the years, ASEAN's attitude towards the Korean nuclear issue is still being fine-tuned. Although the international community has repeatedly issued policies to condemn North Korea and impose economic sanctions, ASEAN is generally neutral and conservative in its attitude towards the DPRK nuclear issue, and it is also very cautious in its actions. Recently, with China and Russia following the United States, they began to impose severe economic sanctions on North Korea, and their words changed to severe condemnation, and ASEAN's attitude towards North Korea also changed subtly. To some extent, the changes of the Korean nuclear issue in ASEAN reflect the constant fine-tuning of ASEAN's foreign policy. This paper aims to find out the fine-tuning of ASEAN's foreign policy and its influence on ASEAN by combing the changes of ASEAN's Korean nuclear issue and the potential reasons behind the changes.

        Product liability (PL), which began enforcement in 2002, refers to the legal responsibility of the manufacturers or sellers (wholesales or retailers) for the property damage or bodily harm caused by their product. With a strong enforcement of the Product Liability (PL) Act, companies are required to structure and operate a response system to defend or prevent product accidents efficiently, but small and medium enterprises (SMEs) are unable to respond more aggressively due to limitation of management resources. In this manner, it is important to develop response strategies for SMEs to efficiently cope with the PL Act. In this paper, the PEST (Political, Economic, Social, and Technological) analysis is performed to reveal the impact of the PL Act on SMEs in macro-economic point of view. To formulate SME’s PL response strategy, SWOT analysis is performed to categorize each factors from PEST analysis and AHP is applied to identify the intensities of SWOT factors. The prioritized SWOT factor, results of PEST-SWOT-AHP analysis, are used to formulate SME’s PL response strategies. The study results are briefly summarized as follows. To reduce product defects, it is necessary for SMEs to formulate PL response strategies for each phase of the product life cycle by continuously collecting and analyzing PL cases in the same industry or for similar products. In addition, SMEs should invest more technological effort to ensure product safety. Further, SMEs should spread PL awareness to all staff members by training internal PL experts. Moreover, a SME should enroll in PL insurance and spread this information to its customers so that they become aware that the company is proactively conforming to the PL law.

        Nilaparvata lugens Stål is one of the important migratory pests of rice paddy fields in Korea. Resistance levels to nine insecticides were monitored in 12 local strains and correlation analysis was conducted to determine cross-resistance relationships among the tested insecticides. The local strains revealed 1.3- to 28.0-, 1.6- to 6.0-, 2.8- to 237.0-, 0.6- to 0.9-, and 0.7- to 1.3-fold resistance to carbamates, organophosphates, neonicotinoids, fipronil and etofenprox, respectively. Organophosphates revealed moderate correlations with benzofuranyl methylcarbamate (r = 0.566 - 0.614, p > 0.01). Three neonicotinoids were not correlated each other, but imidacloprid and clothianidin were moderately correlated with several benzofuranyl methylcarbamate and organophosphate insecticides (r = 0.590 - 0.705, p > 0.05), indicating that unknown common factors (such as detoxification enzymes) might contribute to resistance to both insecticides. Fipronil and etofenprox exhibited low levels of resistance and cross-resistance with other insecticides, suggesting their potential as an effective insecticide for field application. Resistance level monitoring and correlation analysis would be valuable for the selection of appropriate insecticides to control insecticide-resistant N. lugenes, a typical migratory pest in Korea.

        Rapid identification of pest species found under quarantine is an important factor in preventing an economic loss of agricultural commodities. In this study, we analyzed RNA-Seq of the larvae of C. sasakii, G. molesta and G. dimorpha, which are serious pests in several fruits in Korea and are difficult to discriminate by species in their larval stage because of lack of a morphological character. To select immunological diagnostic markers, discriminating the larvae of C. sasakii from the G. molesta and G. dimorpha, RNA-Seq was performed for the larvae of the three insects. The 454 pyrosequencing generated 3,058-4,686 contigs for each three pest species, which assembled into 2,584-3,970 isotigs with average lengths of 829-1,244 bp. Functional annotation of the sequencing results generated 774 orthologs for the three pest species, and 12 isotigs were finally registered as candidate markers for species discrimination through bioinformatical screening, literature search, and gene expression study. The selected candidates include serine proteases, serpins, 27 kDa glycoprotein and storage protein with a constitutive gene expression in their larvae, pupae and adult stage.
