        점점 악화되고 있는 아프가니스탄 상황에 직면 한 트럼프 정부는 아프가니스탄에서 점진적으로 철수할 수 있도록 계획을 수정하였으며, 단기간 안에 미군이 아프가니스탄에서 철수할 수 없기에 아프가니스탄 테러와의 전쟁에서 완전히 승리할 때까지 유지될 것이라고 굳게 믿었다. 미군이 아프가니스탄에서 테러와의 전쟁을 시작한 2001년 이후로 19년이 지난 지금에도 베이징과 워싱턴 사이에 아프가니스탄 문제에 관한 대화나 협력 메커니즘이 없으며, 아프가니스탄과 관련된 모든 주변의 국가들조차도 아프가니스탄 문제를 공동으로 해결하는 것이 중요하다는 것을 인식하지 못하고 있다. 이에 투르크메니스탄, 우즈베키스탄, 타지키스탄 및 파키스탄 등 아프가니스탄의 인근 국가들은 1979년 소련의 아프가니스탄 침공 이후 난민, 마약 및 테러리스트 문제가 발생하고 있다. 본 논문은 아프가니스탄 평화를 목적으로 중국과 미국이 서로 협력할 가능성에 대한 연구했다, 그리고 미래적인 번영(Future of Prosperity)을 구상해봤다. 또한 미국과 아프가니스탄의 문제로 중국의 노력은 아프가니스탄이 가능한 한 빨리 국제 사회의 도움과 협력으로 평화와 안정을 회복 할 수 있기를 희망한다. 결론적으로 중국과 미국이 아프가니스탄 문제에 대해 공통된 관심사를 많이 가지고 있으며 아프가니스탄의 평화와 안정 회복에 대한 합의에 도달할 수 있다고 본다.

        This study examined the effects of an intervention using audiobooks for the development of reading fluency, in terms of reading speed, reading comprehension, and motivation to read among Kazakhstani English as a foreign language (EFL) ninth-grade learners in the K–11 system. Silent reading with audiobooks (experimental group) and silent reading only (control group) were compared with a mixed-method study design, a reading motivation questionnaire, and a semi-structured interview. Quantitative data analysis was conducted using analysis of covariance (ANCOVA). The experimental group was found to significantly outperform the control group in reading speed while preserving substantial comprehension of the texts. The results further revealed that, while both groups’ motivation level increased, no statistically significant difference was found between the experimental and control groups, suggesting that the use of audiobooks was not superior to silent reading for motivation enhancement. Nevertheless, a qualitative analysis of data obtained from the interviews revealed that the use of audiobooks had an overall positive effect on students’ attitudes toward the use of audiobooks and reading comprehension. The study concludes with a discussion of limitations and suggestions for future research.

        Purpose: Despite the effort to bridge the disconnect between educational preparation of competent nurses and employers' expectation of new graduates, there is little known about what nursing competencies are required for new graduates. This paper aims to identify the nursing competencies expected of new graduates, both globally and in the specific Korean context. Methods: An integrative literature review was undertaken. International and Korean computerised databases were searched and 72 relevant papers were appraised using the Mixed Methods Appraisal Tool and the Data Relevance. Twenty-eight studies were selected for final data analysis. Results: Three themes with eleven competency areas were discovered: new graduates are expected to be competent in delivering an evidence-based practice with a patient-centered approach as professional nurses. Competency in evidence-based practice involves being able to integrate theory and skills, utilise contemporary evidence, and undertake a systematic approach. Patient-centred care involves ensuring patient safety, educating the patient and their family, and demonstrating sound interpersonal communication skills with a collaborative approach. New graduates are also expected to practice legal and ethical nursing care, undertake continuing professional development, and demonstrate a capacity for clinical management and appropriate professional attributes. Conclusion: Identifying nursing competencies for new graduates can add a level of detail to the current nursing competencies required for new graduates in the global and the Korean context. The findings can be used not only to inform education providers of potential gaps in preparation for practice of new graduates, but also be used to identify support needed when graduates enter nursing workforce.

        Carbonaceous materials are considered as potential adsorbents for organic dyes due to their unique structures which provide high aspect ratios, hydrophobic property, large efficient surface area, and easy surface modification. In this work, graphene nanoribbons (GNRs) were prepared by atomic hydrogen-induced treatment of single-walled carbon nanotube (SWCNTs), which inspire the idea of cutting and unzipping the SWCNTs carpets with the modified in molecules prevent because of the unfolding of the side-walls. The unfolded spaces and uniform vertical arrangement not only enhance the active surface area, but also promote the electrostatic and π–π interactions between dyes and GNRs. The improved adsorption capacity of GNRs beyond original SWCNTs can be determined by the adsorption kinetics and isotherm, which are evaluated through adsorption batch experiments of the typical cationic methylene blue (MB) and anionic orange II (OII) dye, respectively. It is shown that the adsorption kinetics follow a pseudo second-order model while the adsorption isotherm could be determined by Langmuir model. The results reveal that the maximum adsorption capacities of GNRs for MB and OII are 280 and 265 mg/g, respectively. The GNRs present the highly efficient, cost effective, and environmental friendly properties for the commercial applications of wastewater treatment.

        Donald Trump’s methods of operating and conducting national security and foreign policy are exactly the same as they would be if he was engaged in real estate transactions and deals. To Donald Trump, trade policy, foreign policy, and national security policy are transactions and zero-sum games. My thesis is straightforward: One can draw a straight line from Donald Trump’s ruthless mode of operating in the contentious world of New York real estate to his operations on the world stage today. From Queens to the world stage, there is a straight line from using threats and litigation to avoid commercial and contractual obligations to using threats and litigation in conducting the US foreign and trade policy. Especially as to policies pertaining to the World Trade Organization and the US–China trade relations. His weaponization of tariffs and economic sanctions is now being wielded as a principal tool of the US foreign policy for the first time since the early 1930s.

        Assisted reproductive technologies (ART) merely depend on improving the oocyte maturation and their developmental competence to produce good quality embryos. Oocyte maturation passes through long and complex molecular steps starts from the early embryonic life and ends with sperm fertilization. Oocyte developmental competence can be attained by improving the nuclear and cytoplasmic mechanisms together with some epigenetic maturation. In this review, we highlight the cornerstones of oocyte maturation on both nuclear and cytoplasmic levels. Interfering or supporting these molecular mechanisms would help in the development of novel regulating agents for reproductive performance of humans and livestock species.

        New triple tungstate phosphors NaPbLa(WO4)3:Yb3+/Ho3+ (x = Yb3+/Ho3+ = 7, 8, 9, 10) are successfully fabricated by microwave assisted sol-gel synthesis and their structural and frequency upconversion (UC) characteristics are investigated. The compounds crystallized in the tetragonal space group I41/a and the NaPbLa(WO4)3 host have unit cell parameters a = 5.3927(1) and c = 11.7961(3) Å, V = 343.05(2) Å3, Z = 4. Under excitation at 980 nm, the phosphors have yellowish green emissions, which are derived from the intense 5S2/ 5F4 → 5I8 transitions of Ho3+ ions in the green spectral range and strong 5F5 → 5I8 transitions in the red spectral range. The optimal Yb3+:Ho3+ ratio is revealed to be x = 9, which is attributed to the quenching effect of Ho3+ ions, as indicated by the composition dependence. The UC characteristics are evaluated in detail under consideration of the pump power dependence and Commission Internationale de L'Eclairage chromaticity. The spectroscopic features of Raman spectra are discussed in terms of the superposition of Ho3+ luminescence and vibrational lines. The possibility of controlling the spectral distribution of UC luminescence by the chemical content of tungstate hosts is demonstrated.

        After harvest, Dolcetto cut roses were immediately exposed to air for 0 (E-0), 1 (E-1), 2 (E-2), and 3 h (E-3) and then placed under tap water for recovery. We determined the effect of air exposure time on vase life, water relations, and gene expression of cut flowers. The results revealed that E-0 treatment exhibits a higher postharvest quality of cut flowers than others. E-3 treatment significantly decreased the vase l ife of c ut r oses d ue t o an early f ailure o f water relations, such as larger stomatal size, higher transpiration, shorter time maintaining positive water balance, and the bacterial proliferation. E-0 treatment significantly decreased water stress, maintained leaf chlorophyll fluorescence ratios, and extended the vase life of cut roses. The decrease in water stress of E-0 treated flowers may increase the expression of Rh-PIP2;1 and Rh-TIP in rose petals, resulting in maintained cell turgor and increased flower diameter of cut flowers. These results recommend that a non-exposed harvest can be used for the harvest s tage to improve the postharvest quality of cut flowers. Understanding the relationship between air exposure time and water relations of cut flowers will significantly help in developing distribution systems for assuring cut roses quality.

        Koreans considered themselves as a critical link between the past and future and not as an autonomous individual of now, in contrast to what many westerners emphasized and modern Koreans are beginning to think. This study is to apply the "Asian Jeong Nang silver model" as a spirit of "happiness and dignity of the elderly " as the basic policy for the aging Baby Boomers. The way of life of Jeju Haenyeos was similar to the typical life style of retired Baby Boomers, who had been devoted to social contribution until the last minute, returning expert knowledge to the community. That’s why Haenyeo community was chosen as a typical archetype, as well as other example, for a new silver model development. Cross Cultural Ageing Initiative (CCAI)’s purpose is to promote international exchange and collaboration between Korea and United States for research, education and service for the aging population. To bring together the best practices of the East and West, involving all the stake holders of the wider community such as participants in “the 2021 Global Ageing Network(GAN) Biennial Conference : East meets West: Approaches to Healthy Ageing and Wellness in both Seoul and Jeju Island in S. Korea September by GAN and GAN Korea. In particular, the upcoming “Silver Tsunami” in Korean society shows the necessity of welfare models for Korean baby boomers who have retired as highly educated professionals.

        A warehouse is more than just a place to store goods but also creates a time utility gap between production and consumption that is important in the development of trade and commerce. Malaysia has a high aspiration to be the most popular gateway in Asia. However, Malaysia Productivity Corporation has claimed that particularly in efficiency and productivity aspects, the warehouse industry is less incline to innovate and make improvement to increase. There are ten failure factors that had been identified during literature survey affecting to the warehouse operations efficiency. Therefore, this study intends to analyse and select the main failure factors that mostly affecting the warehouse operations efficiency. A Fuzzy Analytic Hierarchy Process (FAHP) technique has been used in this study to calculate the weight value of each variable through a pair-wise comparison method. The finding highlighted the four main failure factors which are ‘equipment’, ‘environment concern’, ‘special handling consideration’ and ‘human factor’ that influence directly to the warehouse operations efficiency. This paper has contributed to a new knowledge of complex warehouse operation area with recommendations action that shall be taken to manage the possible risk in future, which will also contribute to achieve the government goals.

        For the whole process of circulation, distribution, application of the logistics system is a higher development step of transportation technology. Multimodal transport has linked all modes of transport together to serve the supply and consumption needs of the manufacturer. Currently, when e-commerce (EC) is on the rise, quality logistics and delivery services are the essential stages to achieve success in transactions. e-commerce today is no longer a fashion trend; it is an essential part of the retail industry. EC is changing the game of Logistics. The e-commerce world has been introducing many risks and complex issues that logistics and supply chain experts have never faced. E-commerce is the main impact on terminal logistics (last mile) and warehousing. However, it is also quite interesting to see how e-commerce is impacting airports and seaports. E-commerce is growing actively in Vietnam at a rate of about 25% per year, which is an excellent opportunity for business logistics services to get more orders. Moreover, the Vietnamese logistics market is small but has a high growth rate (20% - 25% / year). In recent times, this market is expected to change the face and grow faster due to the development of electronic retail in Vietnam and e-Logistics logistics trends in the world. However, to meet the requirements, to grasp the opportunities, logistics enterprises need to link to get a closed and synchronized service chain. So logistics companies need to increase information, respond faster, enhance technology to meet flexible processes, establish networks, and business links to meet changing needs. The article shows that the inadequacies and lack of cohesion between logistics service providers and e-commerce are limiting competitiveness, losing opportunities of enterprises, and the economy in the context of healthy industrial revolution 4.0. The assessment of the correlation and connectivity of logistics and e-commerce enterprises in Vietnam in the paper will contribute significantly to the development of Vietnam's economy in the period 2020-2025.

        Illegal, unreported and unregulated (IUU) fishing may occur on the high seas or within a national jurisdiction. Several factors were identified as contributing to the occurrence of IUU fishing activities, among which is poor governance marked by limited and overlapping enforcement by related authorities. With very limited regional enforcement bodies and the absence of a regional multilateral agreement, IUU fishing is difficult to overcome. It means that issues relating to overfishing and other fishing conflicts like foreign vessels intrusions and use of illegal fishing methods will continue to be a problem. This paper identifies the Malaysia’s legal framework governing IUU fishing, as well as relevant international and regional laws and policies. The paper also discusses the devastating effects of IUU fishing to the global fish stocks and national economy. Although the existing framework is considered comprehensive, it recommends further stringent and fair law enforcement to combat IUU fishing in Malaysia’s waters.
