This study evaluated the effects of solid and water-soluble extracts derived from torrefied Pinus densiflora on lettuce (Lactuca sativa) germination and growth, as well as the cultivation efficiency of torrefied materials combined with plant nutrient solutions. Torrefied samples were prepared under various conditions (200°C, 220°C, 240°C for 20–80 minutes) and mixed with sand at ratios from 20% to 100%. Liquid extracts were formulated with macronutrients (N, P, K, Mg) and micronutrients (Mn, B, Fe, Cu) and applied to leafy and root vegetables. Germination tests showed that 60% and 80% torrefied treatments had the highest and most consistent rates, with torrefied samples promoting more rapid and stable germination than controls. A two-way ANOVA indicated a significant interaction between treatment and concentration (p = 0.043), suggesting concentration-specific effects. While shoot length showed no significant difference, root growth was marginally significant (p = 0.064), with washed torrefied material producing the longest roots. Physical analysis revealed that torrefied materials improved soil thermal retention and moisture-holding capacity. However, increasing torrefied content reduced porosity, likely due to fine particles filling soil pores. In conclusion, torrefied P. densiflora materials exhibit strong potential to enhance germination, root development, and soil condition. Optimal results were achieved with 40–60% solid mixtures for germination and 60–80% diluted extracts for rapid and consistent seedling growth. When optimally applied, they may serve as effective, sustainable amendments in cultivation systems.

This study explored the dual linguistic challenges experienced by Chinese international students enrolled in English-Medium Instruction (EMI) programs at South Korean universities. Drawing on semi-structured interviews with 20 undergraduate students from two leading private universities in Seoul, this study investigated how students navigate the linguistic demands of studying in English while simultaneously adjusting to Korean as the dominant campus language. The findings revealed that students encounter significant obstacles, including professors’ limited English proficiency, inconsistent classroom language policies, and marginalization in group work and class discussions. Despite these difficulties, many students gradually adapted through self-directed strategies and peer support, ultimately gaining academic and linguistic benefits. Some participants reported enhanced preparedness for further studies in English-speaking countries and developed bilingual competencies. The study highlights the complex realities of EMI implementation for non-Anglophone international students and calls for more transparent language policies, targeted support programs, and inclusive pedagogical practices to promote equitable learning environments.

The casting manufacturing process of aluminum automotive wheels often involves processing various wheel models during stages such as flow forming, machining, packaging, and delivery. Traditionally, separate equipment or production lines were required for each model, which led to higher facility investment costs and increased labor costs for classification. However, the implementation of machine learning-based model classification technology has made it possible to automatically and accurately distinguish between different wheel models, resulting in significant cost savings and enhanced production efficiency. Additionally, this approach helps prevent product mix-ups during the final inspection process and allows for the quick and precise identification of wheel models during packaging and delivery, reducing shipping errors and improving customer satisfaction. Despite these benefits, the high cost of machine learning equipment presents a challenge for small and medium-sized enterprises(SMEs) to adopt such technologies. Therefore, this paper analyzes the characteristics of existing machine learning architectures applicable to the automotive wheel manufacturing process and proposes a custom CNN(Convolutional Neural Network) that can be used efficiently and cost-effectively.

This study explores a church leader’s perceptions of language policy goals and cultural practices within a Korean-American church, as well as the changes prompted by the COVID-19 pandemic. Drawing on theories of ethnic churches, language planning and policy, and communicative frameworks of organizational identity, the study employs critical discourse analysis and thematic analysis. Data were collected through multiple qualitative methods, including participant observation of English and Korean worship services, two in-depth interviews, audio recordings, and artifact documentation. The findings highlight the dual role of first language and cultural practices in affirming both ethnic identity and Christian faith among Korean congregants. Furthermore, this research illuminates the integrative role of the church—both institutionally and socially—during a global crisis. The church leader’s motto, “Stay well and stay connected,” was expressed through linguistic and cultural adaptations that promoted a sense of belonging and positive identity amidst uncertainty.

Some scholars argue that after the Yuan and Ming dynasties, the function of the character "Dai"(埭) gradually diminished in real life, and the character itself slowly faded from people's view. In modern life, people may occasionally encounter the character "Dai"(埭) in some ancient place names or modern place names that inherit ancient traditions. Others suggest that the use of "Dai" (埭) in place names in Wenzhou, Zhejiang Province, is influenced by the Min dialect. However, this paper holds a different view. In fact, in the provinces and cities south of the Yangtze River, including Zhejiang, Shanghai, Jiangsu, Anhui, and Fujian, the character "Dai"(埭) is very common as a place name, with a higher frequency of use compared to its function as a water conservancy facility. It is by no means "occasional." As a frequently used place name, including in Fujian, it has not faded from people's view at all. Through diachronic examination, it is found that the character "Dai"(埭) has been used as a place name at least since before the Tang Dynasty and has never been (埭) interrupted. It was not only used as a place name after the Yuan and Ming dynasties. The toponymic use of 'Dai' (埭) across Zhejiang, Shanghai, Jiangsu, Anhui, and Fujian can be regarded as a vestige of ancient Chinese linguistic heritage. Many dictionaries, including some well-known ones, have not included the meaning of "place name character" for "Dai," which seems inappropriate. These dictionaries have included the dialectal usage of "Dai"(埭) as a measure word but have overlooked its dialectal place name usage, which is a case of "focusing on one thing while neglecting another."

In the context of higher education (HE) internationalization, English as a Lingua Franca (ELF) plays a crucial role in academic and interactive communication, often intersecting with local languages. This enables greater flexibility in language use and code-switching (CS) between English and the local language. While previous research on English as a Medium of Instruction (EMI) has predominantly examined the perspectives of local stakeholders, the views of international students have been largely underexplored. To bridge this gap, this study investigates the perceptions of both local and international students regarding CS practices within EMI courses across specific classroom situations. The findings reveal that both groups support the conditional use of the local language to promote comprehension while ensuring inclusivity. Local students demonstrate a broader acceptance of CS compared to their international counterparts, particularly in relation to academic outcomes such as understanding instruction and assessment. In contrast, international students show greater receptiveness to CS during interactive classroom discussions, which reflects their attitudes toward engaging with local peers. These insights contribute to the development of more nuanced EMI policies and deepen our understanding of language dynamics in HE contexts where English is not the native language.

This study examined the effects of pre-soaking solvents and repeated steaming-drying (SD) cycles on the antioxidant activity and active compound content of Rehmanniae Radix Preparata(RRP), the processed root of Rehmannia glutinosa Libosch. SD treatments were conducted for 1 to 9 cycles using four different pre-soaking solvents: Takju (a traditional rice wine), Spirits, Honey, and Sugar solution. The results showed no significant differences in DPPH and ABTS radical scavenging activities or in total polyphenol and flavonoid contents among the pre-soaking treatments, although samples pre-soaked in honey and Takju exhibited slightly higher levels. Polyphenol and flavonoid contents increased progressively with the number of SD cycles, reaching levels 2–3 times higher after nine cycles. Catalpol content remained relatively constant regardless of treatment, whereas aucubin content increased in all groups, with the highest accumulation observed in the Takju treatment. Similarly, 5-hydroxymethylfurfural (5-HMF) content increased with the number of SD cycles, with the highest levels found in the honey group, followed by Takju, Sugar, and Spirits. In conclusion, while the type of pre-soaking solvent had minimal influence on antioxidant activities and catalpol content, both aucubin and 5-HMF contents increased with additional SD cycles, with Takju proving particularly effective in enhancing their accumulation.

This study investigates the acute toxicity of sublethal tributyltin (TBT) exposure in the marine polychaetes Perinereis aibuhitensis by measuring changes in mortality, burrowing activity, acetylcholinesterase (AChE) function, and antioxidant defense mechanisms. The 96h-LC50 of TBT was established at 23.7 μg L⁻¹. Following exposure to 1 μg L⁻¹ of TBT led to a dose-dependent reduction in burrowing behavior and AChE activity in polychaetes. Elevated levels of malondialdehyde (MDA) and pronounced reduction of glutathione (GSH) contents explained significant oxidative stress. The major antioxidant enzymes, including GSH peroxidase, GSH reductase, catalase, and superoxide dismutase, were also significantly suppressed following TBT exposure. These findings indicate that TBT-induced acute toxicity compromises physiological functions and undermines antioxidant defense system in polychates.

Growth is a fundamental and vital characteristic of abalone, regulated by both cell number and size, and modulated by growth-related genes. The mollusk-like growth factor (MLGF) is a secreted protein that plays a key role in the growth and development of Pacific abalone. In this study, the growth-specific expression of Hdh-MLGF were analyzed under different conditions commonly encountered by Pacific abalone in aquaculture systems. The expression of Hdh-MLGF varied significantly with growth patterns, showed higher expression in rapid-growing individuals and lower expression in slow-growing abalone. Under starvation conditions, Hdh-MLGF expression was downregulated as the duration of starvation progressed. Under thermal stress, Hdh-MLGF expression increased during the first 12 hours at 25 °C stress. However, at 30 °C, the highest expression was recorded after 6 hours of thermal stress. These results provide valuable insights for future research on this growth factor in abalone and its aquaculture management.

The current US tariff policy has become a focal point of the global trade order, signaling a restructuring of the international economic system established after World War II. The global trade regime is shifting from multilateral cooperation to a landscape increasingly defined by economic and geopolitical competition. The US domestic law is increasingly replacing multilateral mechanisms such as the WTO as the primary legal point at issue and center of gravity influencing and shaping the global trade order. In this transitional phase of order reconstruction, East Asian enterprises should allocate resources to closely monitor geopolitical developments, the US domestic politics, legal frameworks, and ideological trends. They should also establish mechanisms for geopolitical risk management and prioritize risk management over business expansion as a core strategic principle. However, this is not entirely negative; the new research, understanding, and strategic adjustments undertaken by enterprises may lay a deeper foundation for the next wave of globalization.

본 연구는 기업공개(IPO) 과정에서 최고경영자(CEO)의 해외 경험이 IPO의 성공에 미치는 영 향을 탐구하고, CEO가 경험한 국가와 주관사 국적 간 문화적 거리가 이 관계에 미치는 조절효과 를 분석한다. 또한 IPO 기업과 외부 투자자 간의 정보 비대칭성 정도가 CEO 해외 경험의 신호 효 과에 미치는 영향을 살펴본다. 2014년부터 2019년 사이 코스피와 코스닥 시장에 상장한 368개 기업을 대상으로 실증 분석을 진행한 결과, CEO의 해외 경험은 IPO 성공에 긍정적 영향을 미쳤다. 하지만 이러한 긍정적 영향은 CEO가 경험한 국가와 주관사의 국적 간 문화적 거리가 클수록 약화 되었다. 반면 IPO 기업과 외부 투자자 간 정보 비대칭성이 높을수록 CEO의 해외 경험이 IPO 성 공에 미치는 긍정적 효과는 더욱 강화되었다. 본 연구는 도구변수를 사용하여 내생성 문제를 통제 하였으며, 도구변수 사용 시에도 주요 가설은 대체로 지지되었다. 본 연구는 CEO의 해외 경험이 IPO 과정에서 중요한 신호(signal)로 작용할 수 있음을 제시하며, 특히 문화적 거리와 정보 비대 칭성이라는 맥락적 요인이 CEO 특성의 신호 효과를 조절할 수 있음을 밝힘으로써, 기업공개 및 신호 이론 연구에 기여한다. 실무적으로는 IPO를 준비하는 기업들이 해외 경험이 있는 CEO를 선 임하면 도움이 될 수 있음을 시사하고, 주관사를 선택할 때는 문화적으로 유사한 국가의 주관사를 전략적으로 고려할 필요가 있음을 시사한다.

The increasing global economic, social, and political interdependence has led to expanding trade in goods and services. The WTO facilitates international trade by providing a nondiscriminatory trading environment to all member states. Afghanistan started the WTO accession in 2009 and joined as the 164th member on December 18, 2015. This piece examines the legal implications of the WTO membership on Afghanistan’s trade and economy. While membership will expand trade, attract foreign investment, and increase Afghanistan’s market share worldwide, it also means harmonizing domestic regulations with the WTO standards. In addition, lower tariffs on imported goods threaten local industries, leading to job losses, industrial shrinkage, and reduced government income. The study’s findings show that, despite short-term vulnerability, joining the WTO has long-term benefits such as economic growth, increased investment, reduced cost of living, and fairer trade structure.

Asian economic potential draws world attention. Recently, China challenges the US’s economic and political dominance which prompted the US-China trade war. Afghanistan and other Arab nations struggled for decades amid an informal US colony after Saddam Hossain’s fall. After the US troops left Afghanistan in 2021, the Taliban took over it. Afghanistan’s trade and military advantage make it vital as middle east geopolitics alter. This has been noticed by China. China-Afghanistan military cooperation improves trade. All in Eurasia is seeing China penetrate global value networks and the Belt and Road supply chains. The 21st century’s Silk Road connects Eastern Afghanistan’s Wakhan Corridor. China-Afghanistan cooperation along the Wakhan Corridor is the key to the success of the Silk Road initiative. China-Afghanistan wants to use the corridor more, which has been a commerce and military battleground. The essay discusses China- Afghanistan strategic relations along the Wakhan Corridor from a legal and strategic perspective.

본 연구는 국제경영전략 관점에서 해외자회사가 이전한 지식은 기업 경쟁력 강화에 언제나 긍정 적일 것이라는 가정을 비판하기 위해, 해외자회사의 역지식이전 수준과 기업성과 간 관계를 분석하 였다. 글로벌 기업 직원 256명을 대상으로 설문조사한 결과, 해외자회사가 본사로 이전한 지식 수 준이 높을수록 높은 기업성과를 보이는 것으로 나타났다. 그러나 이러한 효과는 해외자회사의 역량 및 해외자회사와 본사 간 비전공유 수준에 따라 차이를 보이는 것으로 나타났으며, 해외자회사의 역량이 낮거나, 비전공유 수준이 낮은 조직의 역지식이전은 기업성과에 부정적 영향을 제공하는 것 으로 나타났다. 이를 통해 본 연구는 역지식이전 과정에서 글로벌 기업의 형태적 통제기제와 사회 적 통제기제가 요구되고 있음을 제시하였다.

This paper explores the illegal Israeli occupation of Palestinian territories, focusing on the West Bank and Gaza after 1967. It employs a qualitative research approach, analyzing primary and secondary sources to examine the legal ramifications of Israel’s ongoing occupation and settlement expansion, which violate international law. The findings highlight that, despite various international resolutions, Israel continues its unlawful presence. Key legal rulings, such as the International Court of Justice’s decision of July 19, 2024 and a UN General Assembly resolution in September 2024, reaffirm the illegality of Israel’s actions. Nonetheless, Israel has ignored these calls for withdrawal and persists in expanding settlements. The paper argues that the UN member states must enforce international legal rulings and hold Israel accountable through international courts. It advocates for the imposition of economic and diplomatic sanctions by the UN Security Council to curb settlement expansion and dismantle existing illegal settlements, emphasizing the need for coordinated international efforts to achieve justice for Palestine.

This study examines the development of the Association of Southeast Asian Nations (ASEAN)’s Self-Certification of Origin mechanism through two key phases. From 1993 to 2015, ASEAN strove to establish a common market and deepen economic integration. During this period, it introduced various pilot projects to enhance trade, streamline certification procedures, and experiment with trade facilitation initiatives. Following the official establishment of the ASEAN Economic Community in 2015, the focus shifted towards harmonizing trade procedures, enhancing regional coordination, and standardizing customs processes. These efforts culminated in the launch of the ASEANwide Self-Certification (AWSC) in 2020. In Vietnam, however, the implementation of AWSC has faced significant challenges. Despite these obstacles, the country has taken proactive steps to integrate AWSC into its trade system by issuing domestic regulations and guidance from regulatory authorities. This study explores the specific difficulties Vietnam faces in implementing AWSC and proposes recommendations to enhance its effectiveness.

The Indian Ocean is the second-largest tuna fishing ground in the world, accounting for approximately 1.2 million tonnes (23%) of the estimated 5.2 million tonnes of global commercial tuna catch in 2023. This study examined the relationship between tuna catches, specifically skipjack, bigeye, and yellowfin tunas, and prey biomass (Nautical Area Scattering Coefficient, NASC) estimated from acoustic surveys conducted in the southwestern Indian Ocean from 20 April to 15 May 2019. Environmental variables were derived from the Copernicus Ocean Model, and tuna length data from the IOTC. The estimated total tuna catch in the study area was approximately 166,400 tonnes, with the northwestern region showing the highest catches and NASC values. Tuna catches increased with NASC; however, the relationship was non-linear. While skipjack showed no significant correlation with NASC, bigeye and yellowfin tunas exhibited weak but significant positive correlations. Environmental analysis revealed that the northern waters had high surface temperatures, low salinity, and low oxygen levels, with mid and deep layers characterized by low temperature, salinity, oxygen, and chlorophyll. These findings offer a foundation for understanding tuna distribution in relation to prey and environmental conditions, highlighting the need for future species- and fishery-specific studies to support sustainable tuna resource management.

가속화되는 글로벌 환경 속에서 현지 소비자를 유인하기 위한 효과적인 전략에 대한 논의가 활발 히 이루어지고 있다. 특히, 브랜드 글로벌성을 강조한 글로벌 소비자 문화 포지셔닝과 현지 문화 어필을 통해 친밀감을 높이는 현지 소비자 문화 포지셔닝은 해외 기업에게 있어 효과적인 마케팅 커뮤니케이션 구축을 위한 주요한 의사결정 요인이다. 본 연구는 글로벌 패션 매거진의 내용 분석 을 통해, 패션 브랜드의 매거진 광고에 있어 소비자 문화 포지셔닝의 트랜드를 탐색하고자 한다. 특히, 패션 매거진의 경우, 제품의 속성에 대한 직접적인 정보 전달보다 유명인 광고를 통해 브랜 드 메시지 및 이미지를 전달하는데 초점을 두고, 유명인 광고에 있어 글로벌 혹은 현지 소비자 문 화 포지셔닝의 행태를 탐색하고자 한다. 또한, 유사한 문화권임에도 글로벌성과 현지성의 선호에 따른 브랜드의 전략적 방향이 다를 수 있음을 기반하여, 중국과 일본의 패션 매거진의 내용 분석을 통해 유명인 광고의 차이를 확인하고자 한다. 이를 위해 글로벌 패션 매거진으로 대표되는 Vogue 및 GQ가 2023년에 중국과 일본에서 발행한 패션 매거진을 기반으로 내용 분석을 실시하였다. 분 석 결과, 중국의 경우 현지성을 강조한 유명한 광고의 빈도가 높은 것으로 나타났으며, 글로벌 명 품 브랜드의 경우, 중국과 일본 모두에서 표준화된 글로벌 접근이 지배적인 것을 확인하였다. 본 연구는 패션 매거진의 통합적인 내용 분석을 통해 유명인 광고의 글로벌성과 현지성의 패턴을 비교 분석하였다는 점에서 학문적인 의의가 있으며, 유명인 광고의 패턴은 국가별 차이가 있음을 확인하 고, 특히 중국의 경우, 소비자 친밀감 및 신뢰감을 기반한 현지 소비자 문화 포지셔닝의 중요성을 시사하였다는 점에서 의의가 있는 것으로 판단된다.

This study aimed to enhance the operational efficiency and safety of offshore eel trap fisheries by developing six types of automated fishing equipment: a bait crusher, bait cutter, main line arranging device, trap cleaning device, eel sorting device, and fish pump system. Sea trials demonstrated that the bait crusher and bait cutter significantly reduced manual labor and processing time while maintaining bait quality. The main line arranging device improved productivity and safety by automating the sorting of looped cords. The trap cleaning device effectively removed fouling organisms using high-pressure water and rotating brushes. The eel sorting device enabled automatic size-based selection, improving resource management and operational efficiency. The fish pump system transferred eels rapidly with minimal physical damage, reducing unloading time by over 80% and decreasing labor requirements. A satisfaction survey of fishery participants confirmed that all developed devices were highly effective in reducing workload, enhancing safety, and improving operational performance. The automated equipment developed in this study is expected to contribute to the sustainable management of offshore eel trap fisheries and to offer potential applicability to other coastal and offshore fisheries.
