This study investigated the relationship between changes in language learning beliefs and English proficiency among 41 Korean university students who participated in a short-term English program. Participants’ beliefs were assessed using the Beliefs About Language Learning Inventory (BALLI), and their proficiency was measured using the Test of English for International Communication (TOEIC). Frequency analysis, descriptive statistics, paired-sample t-tests, and correlation analysis were employed to analyze the data. The study found significant improvements in both listening and reading scores, and changes in beliefs varied with proficiency gains. Students with higher proficiency gains demonstrated improved confidence and self-efficacy, and decreased instrumental motivation, whereas those with lower gains exhibited minimal changes in beliefs. Correlation analysis revealed that belief shifts, such as reduced selfconsciousness and increased integrative motivation, were positively related to proficiency gains. These findings suggest the dynamic nature of learners’ beliefs and their potential impact on language learning outcomes, highlighting the importance of addressing belief systems in English language education.

This study examined the feeding behavior and growth performance of 31 Hanwoo steers (10 months old; 278 ± 36.13 kg) within a precision livestock farming system using Roughage Intake Control (RIC) units for real-time data collection. Feeding behavior traits were derived from RIC database data using R software, with subsequent analysis conducted using SAS software. The results indicated that the steers visited the feed stations every 31.12 ± 11.99 minutes, averaging 11 ± 3.37 visits/day. Each feeding session lasted an average of 5.90 ± 1.55 minutes, resulting in a feed intake rate of 77.98 ± 22.53 g/min. Mean daily feed intake was 4.76 ± 1.36 kg, and body weight increased consistently, reaching an average of 412 ± 43.44 kg, with an average daily gain (ADG) of 1.26 ± 0.38 kg. Pearson correlation analysis revealed a strong relationship between daily feed intake and visit duration (r² = 0.621; p < 0.01) and an inverse correlation between daily feed intake and feed intake duration (r² = −0.445; p < 0.05), indicating behavioral adaptation. These findings highlight the importance of monitoring feeding behavior traits concerning growth performance, enhancing our understanding of individual animal behavior and its implications for productivity while emphasizing the role of advanced technologies in optimizing feed utilization in confined livestock systems.

Sustainable development is a critical global priority, as showed by United Nations' Sustainable Development Goals (SDGs). Effective logistics are crucial for achieving several SDGs so that improvements in Logistics Performance Index (LPI) often align with progress in SDG scores. For ASEAN countries, they may fall short of achieving 90% of their targeted SDGs and struggle to challenges of LPI fluctuations. By calculating the correlation between LPI and SDG scores in R software, this study seeks to explore the relationship between logistics performance and progress toward the SDGs in ASEAN countries from 64 secondary observations. As a result, the increasing logistics performance can greatly impact on the population well-being, accessibility, new energy approach, infrastructure formation, and sustainable production and consumption (G1, G3, G7, G9, G12) in ASEAN countries. The study contributes a background for national policymakers in the region to develop the sustainable logistics.

Objective: To examine published qualitative studies that can inform occupational therapists about potential intervention targets to improve health outcomes in homeless communities. Methods: A search was conducted for pertinent studies in the following databases: PubMed, Ovid, and CINAHL. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed to extract relevant data. Only research published after 2011 in English-language peer-reviewed journals was included. Twelve of the 1,162 identified articles satisfied the requirements for inclusion. Results: Individuals experiencing homelessness had higher levels of food insecurity, mental health conditions, and inadequate management of chronic conditions than those with a stable residence, all of which were successfully treated through occupational therapy. Conclusion: The scope of practice of occupational therapists allows for holistic treatment approaches to address the biopsychosocial health of homeless individuals at all levels of need and suggests that occupational therapy intervention initiatives are appropriate to address occupational justice for this population

The cost of treating water purification plant water treatment residuals is high, with a low recovery rate and unstable effluent water quality, particularly in plants using lake and reservoir water sources in severe cold regions. Maximizing water resource utilization requires integrating water treatment residuals concentration and treatment effectively. Here, ceramic membrane technology was employed to separate supernatant and substrate after pretreatment. Optimal settling was achieved using 75 μm magnetic powder at 200 and 4 mg/L of nonionic polyacrylamide co-injection. Approximately 65% of the separated supernatant was processed by 0.1–0.2 μm Al2O3 ceramic membranes, yielding a membrane flux of 50 L/m2h and a water recovery rate of 99.8%. This resulted in removal rates of 99.3% for turbidity, 98.2% for color, and 87.7% for color and permanganate index (chemical oxygen demand, COD). Furthermore, 35% of the separated substrate underwent treatment with 0.1–0.2 μm mixed ceramic membranes of Al2O3 and SiC, achieving a membrane flux of 40 L/m2h and a water recovery rate of 73.8%. The removal rates for turbidity, color, and COD were 99.9%, 99.9%, and 82%, respectively. Overall, this process enables comprehensive concentration and treatment integration, achieving a water recovery rate of 90.7% with safe and stable effluent water quality.

Graphene-based solar cells and supercapacitors integrated into photosupercapacitors represent a pioneering advancement. These devices leverage the exceptional properties of graphene, such as high conductivity and large surface area, to enhance both solar energy conversion and energy storage. The integration of these technologies into photosupercapacitors creates a multifunctional device capable of harnessing solar energy and storing it efficiently. This innovative approach holds promise for sustainable and versatile energy solutions, marking a significant step towards developing efficient and compact energy storage systems. This integration addresses the intermittent nature of solar power generation by providing a continuous and reliable power supply through energy storage. Supercapacitors are one such energy device with a high-power density and excellent specific capacitance which is integrated will a dye-sensitized solar cell (DSSC) comprising a single system of photosupercapacitor. A novel electrode material of NiO/CuO/Co3O4/rGO was synthesized which serves as the Pt-free counter electrode of DSSC and working or storage electrode of supercapacitor later was used as the intermediate electrode and storage electrode of a photosupercapacitor. The integrated photosupercapacitor device had a photovoltage of 0.81 V with arealspecific capacitance, energy and power density of 190.12 mF cm− 2, 17.325 μW h cm− 2 and 0.162 mW cm− 2, respectively. The device self-discharged in 385 s with an overall conversion efficiency of 2.17%, resulting in a self-charged energy device.

Gold nanoparticles (Au NPs) decorated carbon nanofibers (CNFs) have been prepared by an electrospinning approach and then carbonized. The prepared Au-CNFs were employed to modifying a screen printed electrode (SPE) for simultaneous determination of ascorbic acid (AA), dopamine (DA) and uric acid (UA). Au NPs are uniformly dispersed on carbon nanofibers were confirmed by the structure and morphological studies. The modified electrodes were tested in cyclic voltammetry (CV), differential pulse voltammetry (DPV) and chronoamperometry (CA) to characterize their electrochemical responses. Compared to bare SPE, the Au-CNFs/SPE had a better sensing response to AA, DA, and UA. The electrochemical oxidation signal of AA, DA and UA are well separated into three distinct peaks with peak potential separation of 280 mV, 159 mV and 439 mV between AA-DA, DA-UA and AA-UA respectively in CV studies and the corresponding peak potential separation in DPV studies are 290 mV, 166 mV and 456 mV. The Au-CNFs/SPE has a wide linear response of AA, DA and UA in DPV analysis over the range of 5–40 μM ( R2 = 0.9984), 2–16 μM ( R2 = 0.9962) and 2–16 μM ( R2 = 0.9983) with corresponding detection limits of 0.9 μM, 0.4 μM and 0.3 μM at S/N = 3, respectively. The developed modified SPE based sensor exhibits excellent reproducibility, stability, and repeatability. The excellent sensing response of Au-CNFs could reveal to a promising approach in electrochemical sensor.

Graphitic nitrogen-doped carbon film/nanoparticle composite, in which the films were wrapped and separated by the nanoparticles, was prepared through a simple co-calcination route. Due to its unique porous structure and improved nitrogen content, the as-prepared electrode material could exhibit high specific capacitances of 317.5 F g− 1 at 0.5 A g− 1 and 200.0 F g− 1 at 20 A g− 1, and stable cycling behavior with no capacitance decline after 10,000 cycles in three-electrode system. When assembled in two-electrode capacitor, its specific capacitance could be well kept at 265.5 F g− 1 at 0.5 A g− 1, and thus the supercapacitor with a high energy density of 9.22 Wh kg− 1 was obtained. The superior energy storage properties of the as-prepared material indicate its promising application as high-performance carbon-based electrode for supercapacitors.

In recent years, the search on fabrication of highly efficient, stable, and cost-effective alternative to Pt for the hydrogen evolution reaction (HER) has led to the development of new catalysts. In this study, we investigated the electrocatalytic HER activity of the Toray carbon substrate by creating defect sites in its graphitic layer through ultrasonication and anodization process. A series of Toray carbon substrates with active sites are prepared by modifying its surface through ultrasonication, anodization, and ultrasonication followed by anodization procedures at different time periods. The anodization process significantly enhances the surface wettability, consequently resulting in a substantial increase in proton flux at the reaction sites. As an implication, the overpotential for HER is notably reduced for the Toray carbon (TC-3U-10A), subjected to 3 min of ultrasonification followed by 10 min of anodization, which exhibits a significantly lower Tafel slope value of 60 mV/dec. Furthermore, the reactivity of the anodized surface for HER is significantly elevated, especially at higher concentrations of sulfuric acid, owing to the enhanced wettability of the substrate. The lowest Tafel slope value recorded in this study stands at 60 mV/dec underscoring the substantial improvements achieved in catalytic efficiency of the defect-rich carbon materials. These findings hold promise for the advancement of electrocatalytic applications of carbon materials and may have significant implications for various technological and industrial processes.

Nanoparticles, especially those derived from plant extracts, are becoming increasingly popular as a bio-based, environmentally friendly alternative to conventional technologies. The Maui rose, a flowering plant with medicinal and therapeutic properties, is one of the most important of these materials because its extract component has antibacterial, antioxidant and anti-inflammatory biological activity. In this work, we report on synthesizing and characterizing iron oxide nanoparticles (Fe2O3) extracted from flower plants (Borago), to create persistent and environmentally friendly antibacterial agents. As part of the chemical formation process, Fe2O3 nanoparticles were extracted from specific flower plants utilizing a series of carefully regulated chemical reactions. X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and atomic force microscopy (AFM) of the samples were studied. The nanoparticles produced were analyzed using common microbiological methods and studies (EDS). The antibacterial activity of the Fe2O3 nanoparticles and their effect on a range of microorganisms were evaluated. The results demonstrated that Fe2O3 nanoparticles were successfully synthesized with a specific crystal structure and good anti-bacterial activities.

During the period of 1959 to 1984, North Korean false propaganda led over 90,000 ethnic Koreans and their families to migrate from Japan to North Korea. Once in North Korea, the migrants suffered severe discrimination and human rights abuses. For decades, there was little prospect of justice for these abuses. In recent years, however, survivors of this migration who escaped North Korea have renewed efforts to gain some type of recognition and compensation. This note reviews three of these attempts: lawsuits in Japanese and South Korean courts, as well as a petition that was brought before the Korean Truth and Reconciliation Commission. While each of these avenues has helped bring to light the truth of North Korean deception, more work remains to be done with respect to collecting compensation.

More than 5 billion people will use the Internet and social media by the end of 2024 and global influencer marketers reached USD 24 billion in early 2024. A regulation is thus needed to protect domestic consumers from the negative effects of global influencer marketing, such as deception, hidden advertising, and information uncertainty. Can the current legal framework effectively protect domestic consumers from misleading or deceptive and illegal advertising conducted by influencers through social media platforms from outside of their jurisdiction This essay first examines social influencing and explains how social influencers operate across national borders. It then discusses domestic legislation governing social influencers in China, Japan and South Korea and discusses why these domestic frameworks provide scant protection for consumers against false advertising and misinformation originating in another country. Finally, this essay proposes an international solution to a problem that will only increase size and severity in the future.

Under Trump and Biden, the US trade policy has veered away from its traditional approach, developed since World War II, from multilateralism to focusing primarily on national and unilateral concerns. At the center of this approach have been tensions with China. This includes a renewal of industrial policies, protectionism and, most importantly, reliance on national security, manifested by newer and unexpected geopolitical developments. The discussion of trade policy today has become very toxic, especially during this presidential campaign season, with its renewed focus on tariffs. The trade debate in the US is now entering a new stage with the nomination of Kamala Harris and J.D. Vance. I believe the US drift away from the postwar policies of promoting global trade and investment will continue. Nationalist and protectionist policies will continue as part of a new economic and industrial policy, fused with national security concerns and rhetoric, no matter who wins.

The ongoing conflict in Gaza strip has resulted in significant humanitarian crisis, with civilians often bearing the brunt of violence. This article critically examines the role of IHL in the protection of civilians affected by the armed conflict. The study focuses on key IHL principles, including distinction, proportionality, and precaution, and assesses their application by the parties involved. It employs an analytical and descriptive research methodology. The findings reveal that both Israel and Hamas have committed numerous violations of IHL, including indiscriminate attacks and failure to protect civilian populations. Despite the clear legal frameworks set by IHL, the lack of accountability and enforcement has hindered its effectiveness. The author concludes that while IHL provides a robust legal framework for civilian protection, the political complexities of the Israel-Hamas conflict severely limit its implementation, leaving civilians vulnerable. The research calls for stronger international mechanisms to ensure compliance with IHL and improve civilian protection in the region.

Following the attack on Israel by Hamas militants on October 7, 2023, Israel declared war on the Gaza Strip. In the relentless and nonstop bombardment of the Gaza Strip, about 40,000 Palestinian civilians have lost their lives, the majority of whom were children and women. Additionally, more than 92,000 Palestinians have been injured and many more are still missing or under the rubble. The dire situation in the Gaza Strip requires a firm stand from the international community, as what is happening to the Palestinian people is nothing short of genocide. This paper discusses Israel’s attacks on the Gaza Strip and illustrates how these actions meet the criteria for war crimes, crimes against humanity, and genocide. It also discusses the case filed by South Africa against Israel in the International Court of Justice, alleging that Israel has violated the Convention on the Prevention and Punishment of the Crime of Genocide.

Regional economic integration organizations (REIOs) can ratify climate change agreements as mixed agreements, including the Paris Agreement, with their member states. A question may arise on what responsibilities can REIOs have under the Paris Agreement in relation to the member states. Analyzing the draft articles on the responsibility of international organizations reveals that REIO can have derived (indirect) responsibility for non-fulfilling the obligations by member states due to the normative control resulting from the adoption of binding resolutions. Also, under Article 4.18 of the Paris Agreement, REIO will be jointly responsible for non-realization of the goals communicated in the NDCs together with non-compliant member. This will make the non-compliant states responsible externally to the third parties and to REIO internally in achieving the goals of NDC and will encourage the compliant member states to participate in realizing the collective goal of REIO because of influence of not realizing the collective goal.

Parallel importation of patented products, “first sale doctrine,” is an effective and efficient way of handling the importation of patent-protected goods. The national exhaustion idea is being used in Pakistan regarding patent exhaustion. Market competition and lower pricing phenomena are affected by this strategy. Case studies from the European Union (EU), the United States (US) and China are used to show how businesses can protect consumers’ rights by parallel imports. The US and China follow international exhaustion whereas the EU follows the regional exhaustion principle, which is comparable with Pakistan concerning the Shanghai Cooperation Organization (SCO). By finding lower-priced products, promoting international economic integration and regional collaboration with SCO, Pakistan can avail better investment opportunities. Case studies show result-oriented efforts regarding the implementation of the international parallel exhaustion strategy. Study recommends raising awareness and enhancing legal clarity, IP protection, and stakeholder input to ensure compliance with an international exhaustion system.

이 연구에서는 카자흐스탄의 난민 관련 법제와 1951년 난민협약 및 의정서 의 준수와 관련된 문제점을 살펴보고자 한다. 현재 카자흐스탄은 난민 수용을 많이 하는 여러 국가들과 달리 난민 및 망명 신청자 문제를 다루기 위한 포괄 적인 법제가 부재한 상황이다. 카자흐스탄은 1990년대 후반에 난민협약 및 관 련 국제 조약을 비준하였음에도 불구하고, 국내 이행을 위한 법안을 2009년이 되어서야 통과시켰다. 이 과정에서 카자흐스탄의 자결권 행사와 국제인권법 준 수 간에 대립된 바가 있다. 또한 지나치게 정치화된 시스템은 인도주의 법 준 수보다 정치적 의제를 우선시하여 국제적 의무를 이행하지 못한다는 비판도 제 기되고 있다. 이러한 배경하에 이 연구에서는 카자흐스탄의 난민, 망명 신청자, 무국적자의 법적 지위에 관한 몇 가지 문제점을 지적한다. 첫째, 1951년 난민 협약과 이를 이행하기 위한 국내 난민법 간에 많은 차이가 있으며, 대표적으로 강제송환금지의 원칙이 준수되지 않는다는 점이다. 둘째, 망명 신청자를 위한 ‘보충적 보호’에 관한 조항이 포함되어 있지 않다. 셋째, 카자흐스탄에서 난민 지위는 1년 동안만 부여되는 반면 인근 중앙아시아 국가들은 보다 더 긴 기간 을 허용한다는 점에서 비교된다. 넷째, 무국적자에 대한 행정 절차상 문제가 제기된다. 특히, 국제협약에 부합하는 입법 조치를 통해 무국적자를 판단하기 위한 구체적인 절차가 확립되어 있지 않다. 마지막으로, 망명 신청자가 망명 신청에 대한 결정이 내려지기 전에 강제로 송환된 사례가 있는데 이것은 명백 한 국제법 위반 해당된다. 아울러 해상에서 난민 및 망명 신청자를 송환하는 경우 강제송환금지의 원 칙을 해상 국경에 접한 공해상에서도 적용할 수 있다. 카스피해는 카자흐스탄 을 포함한 5개국을 둘러싼 중앙아시아 최대 내해이며 이 지역의 해상난민을 차 단하는 유일한 경로이다. 난민 이동과 관련된 독특한 지리적 특징에 가지고 있 으나 육상과 항공으로 국경을 넘어오는 것이 우세하기 때문에 카스피해를 너머 로 피난처를 찾는 것은 사실상 실효성이 없다. 최근 유라시아 국가들의 대규모 이주 흐름으로 인해 많은 난민과 망명 신청 자들이 카자흐스탄에 망명을 꾀할 것으로 예상된다. 따라서 카자흐스탄 정부는 난민 보호를 위해 난민에 대한 국내법을 개정하여 국제 의무를 가장 효과적으 로 준수할 필요성이 있다.
