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.

대한민국 정부들은 복지국가를 시대적 과제로 천명하고 있음에도, 낮은 복지 지출과 높은 사회적 불안이 라는 현실에 직면해 있다. 본 논문은 이러한 상황을 타개하기 위한 전략으로 복지국가 ‘체제’의 기획을 제안 하며, 그에 필요한 관점과 방향성을 얻기 위해 복지국가이론의 계보를 탐색한다. 먼저, ‘전후 복지국가’의 팽창을 설명하는 이론들을 고찰하고, 복지체제론을 통해 그 성숙과 위기 대응 양상도 살펴본다. 다음으로, 새로운 사회경제적 환경에 조응하여 진행되는 복지국가의 재구조화, 즉 ‘탈(脫) 전후 복지국가’의 등장을 설명하는 현대 이론들을 종합적으로 검토한다. 이렇듯 복지국가이론의 계보를 살피는 것은 현행 제도의 구 조와 작동원리를 이해하고 미래 기획을 위한 아이디어를 얻는 과정이자, 대한민국이 사회권적 기본권이 적 극 구현되는 나라로 나아가는 데에 필요한 지적 토대를 쌓는 일이라고 본 논문은 주장한다.

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 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.

본 논문은 초국가적 종교 인식론적 공동체의 관점에서 탈동성애 운동 의 세계정치적 양상을 분석한다. 일반적으로 탈동성애 운동은 동성애 정 체성을 벗어났다고 주장하는 개인들에 의해 주도되는 지역적·문화적 현 상으로 여겨지지만, 실제로는 서구권의 보수적 복음주의 세력이 주도하 는 조직화된 국제 네트워크임을 확인할 수 있다. 이러한 네트워크는 특 정 분야의 정책 형성에 영향을 미치는 지식과 권위를 공유하는 전문가 집단, 즉 인식론적 공동체로서 기능한다. 특히 탈동성애 운동의 종교 보 수 활동가들은 자신을 인간의 성(性)에 관한 전문가로 규정하고, 과학적 외형을 갖춘 증거, 헌법적·권리 기반의 논리, 개인의 간증 등 다양한 전 략을 활용하여 동성애가 변화 가능하며 바람직하지 않은 것이라고 주장 한다. 본 연구는 한국을 주요 사례로 삼아, 한국의 보수적 복음주의 엘리 트들이 서구(특히 미국)의 복음주의자들로부터 탈동성애 담론과 전략을 체계적으로 수입하고 현지화한 방식을 경험적으로 분석한다. 구체적으로, 한국의 활동가들이 초국적으로 유통되는 진정성, 피해자성, 인권과 같은 자유민주주의적 레토릭을 전략적으로 차용하여, 자신들의 LGBTQ+ 인권 반대 활동을 종교의 자유 및 주체적인 삶의 경험(lived experiences)의 정당한 표현으로 재구성하고 있음을 보여준다.

본 연구는 우즈베키스탄 자동차 산업 발전에 있어 리버스 엔지니어링 의 역할을 탐구하며, 특히 노나카와 타케우치의 지식 창출 모델(SECI Model)과의 통합에 중점을 두고 있다. 우즈베키스탄이 경쟁력 있는 국내 산업을 구축하고자 노력함에 따라, 리버스 엔지니어링은 해외 기술의 습 득, 적용, 그리고 국산화를 가능하게 했다. 본 연구는 정성적 사례 연구 접근법을 활용하여 기업 보고서, 정책 문서, 학술 문헌을 바탕으로 1996 년부터 2024년까지의 발전 상황을 분석한다. 연구 결과에 따르면 리버스 엔지니어링은 지식 이전과 혁신을 지원해 왔지만, 제한된 R&D 역량, 수 입 부품 의존도, 그리고 취약한 지식재산권 보호 등의 과제가 여전히 남 아 있다. 이러한 장벽을 극복하기 위해 본 연구는 전략적 정책, 국내 혁 신에 대한 투자 확대, 그리고 AI 기반 설계 프로세스 도입을 권고한다.

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.

The US is in conflict with China over various trade issues. Although both countries agreed to temporarily suspend tariffs for the next 90 days, this trend is expected to continue after then. New related to tariffs has been a daily occurrence in the first 100 days of the Trump presidency, and yet a gap remains between the US and China that is difficult to bridge. This seems to stem from the fact that President Trump wants to “Make America Great Again” with a vengeance. In addition to implementing a new tariff system, the US seems to be moving towards supporting “strong patents” to safeguard intellectual property rights. These policies will significantly impact both the US and other nations worldwide. This article explores the external developments in the aftermath of the US presidential election and reviews current issues related to intellectual property in the US, focusing on tariff imposition and the prevailing emphasis on strong patent rights.

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.

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 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.

The selection of topics to be included in the long-term program of work is a part of the working methods of the International Law Commission. A good selection of topics provides a good start to the Commission’s work and fulfills its double function of the progressive development and codification of international law. The process of selecting works for the longterm program of work now faces numerous challenges such as the appearance of new areas of international law and the increased engagement of States and international organizations in the preparation of new conventions outside the Commission’s channel. The challenges call for further improvement of criteria for the selection of works to preserve and enhance the quality of the Commission’s work. This article will briefly highlight the process of the selection of works in the Commission’s history and focus on the implementation of criteria for the selection of topics used during various times, and their advantages and limitations.

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.

This study examined the offshore eel trap fishing process using one year of fishing logs and fishermen’s insights to identify key operational challenges and propose equipment improvement for greater efficiency and safety. Conger eel catches varied significantly by season, depth, and temperature, peaking in winter at 85–90 m and 23°C. The western waters of Jeju Island were identified as a major fishing ground, with the highest catch recorded in November and the lowest in July, reflecting seasonal trends. Each fishing operation deployed about 10,000 traps, with an average loss of 38 traps, posing economic concerns. The process involved intensive manual labor in bait preparation, trap retrieval, catch separation, line loading, and unloading, leading to high physical demands and safety risks. To address these issues, the study proposed automation through the development of a line loading device, trap cleaning device, bait processing machine, and automatic catch separator. These innovations could reduce the labor force required by one to two workers per process, alleviate workloads, and enhance resource management. By integrating quantitative logbook analysis with field-based knowledge, this study offers practical value. Further research is recommended on automation development, cost-effectiveness, and field validation to support safer and more sustainable eel trap fisheries.

21세기에 태어난 최초의 세대인 알파세대(Generation Alpha)는 디지털 네이티브로서 스마트 기기, 소셜 미디어, 인공지능(AI) 등의 신기술 과 밀접한 관계를 맺고 있다. 본 연구는 알파세대의 특성과 이들이 처한 기술적 환경을 분석하고, 이들에게 효과적으로 복음을 전하기 위한 전략을 탐색한다. 알파세대는 출생부터 스마트폰, 태블릿, 인공지능 스피커 등과 함께 성장했으며, 소셜 미디어를 통해 정보 습득과 소통을 자연스럽게 익힌다. 이들은 글로벌 감각이 뛰어나며, 빠른 정보 소비와 시각적·경험적 학습을 선호하는 특징을 가진다. 그러나 기술 의존도가 높은 만큼 정보 과부하, 짧아진 집중력, 영적 관심 저하, 디지털 우상화 등의 위험에도 직면해 있다. 이러한 변화 속에서 전통적인 복음 전도 방식만으로는 알파세 대의 신앙 형성이 어렵기 때문에, 본 연구는 인공지능(AI), 빅데이터, 가상현실(VR), 증강현실(AR) 등의 기술을 활용한 맞춤형 전도 전략을 제안한다. 이를 통해 알파세대가 복음을 직관적으로 경험하고 능동적으로 참여할 수 있도록 돕는 새로운 복음 전도 모델을 제시하며, 한국 교회의 미래 선교 방향성을 제안하고자 한다.

This article examines the process and challenges involved in designing and implementing an ETS in Vietnam, exploring the necessary policy frameworks, institutional structures, and market mechanisms. It highlights key considerations such as the selection of sectors and entities to be covered, the allocation of emission allowances, and the establishment of new market management solutions. This article concludes with strategic recommendations to support the development of a successful and sustainable ETS mechanism in developing country like Vietnam.

The development of offshore wind energy plays a pivotal role in Taiwan’s transition to a lowcarbon economy. To secure the profits of substantial investments in offshore wind energy, long-term contracts are essential. However, supervening incidents could halt, damage, or destroy offshore wind projects. Force majeure clauses serve as a preventive mechanism to address these unforeseen risks. Despite their significance, contract drafters often overlook the importance of force majeure clauses. This article contends that offshore wind developers and the Taiwanese government should collaborate as partners to carefully draft force majeure clauses in offshore wind contracts, ensuring proper allocation of unforeseen risks. By examining the concept of force majeure under the CISG and Taiwanese law, this article proposes fundamental elements and a model clause for force majeure in offshore wind contracts.
