Published: December 2020

Background
AKI after surgery is associated with high mortality and morbidity. The purpose of this study is to develop and validate a risk prediction tool for the occurrence of postoperative AKI requiring RRT (AKI-dialysis).

Methods
This retrospective cohort study had 2,299,502 surgical patients over 2015–2017 from the American College of Surgeons National Surgical Quality Improvement Program Database (ACS NSQIP). Eleven predictors were selected for the predictive model: age, history of congestive heart failure, diabetes, ascites, emergency surgery, hypertension requiring medication, preoperative serum creatinine, hematocrit, sodium, preoperative sepsis, and surgery type. The predictive model was trained using 2015–2016 data (n=1,487,724) and further tested using 2017 data (n=811,778). A risk model was developed using multivariable logistic regression.

Results
AKI-dialysis occurred in 0.3% (n=6853) of patients. The unadjusted 30-day postoperative mortality rate associated with AKI-dialysis was 37.5%. The AKI risk prediction model had high area under the receiver operating characteristic curve (AUC; training cohort: 0.89, test cohort: 0.90) for postoperative AKI-dialysis.

Conclusions
This model provides a clinically useful bedside predictive tool for postoperative AKI requiring dialysis.

Abstract
This paper demonstrates highly efficient GaN high-electron-mobility transistors (HEMTs) on GaN substrates with reduced interface contamination. By applying a hydrofluoric acid-based pre-growth treatment to a GaN substrate, the Si impurity concentration at the interface between the GaN substrate and the epitaxial layer can successfully be reduced. RF performance was enhanced by pre-growth treatment owing to the suppression of Si-induced parasitic loss. As a result, GaN HEMTs on GaN substrates exhibited an excellent power-added efficiency of 82.8% at a 2.45 GHz. To the best of our knowledge, this exceeds that of the previously reported discrete GaN HEMTs at around this frequency range.

Permasalah komunikasi interpersonal bagi pelaut wanita yang bekerja di kapal terhadap perwira yang merupakan Warga Negara Asing (WNA) dapat menyebabkan terganggunya keselamatan pelayaran. Kurangnya pihak perusahaan pelayaran dalam memikirkan dan memperhatikan kesejahteraan pelaut wanita menyebabkan penurunan produktivitas kerja dan kurangnya komunikasi interpersonal di atas kapal. Komunikasi yang buruk antar individu menyebabkan kontroversi, dan pertentangan diantara satu pihak atau lebih. Hal ini terjadi akibat salah satu pihak mempersepsikan adanya pihak lain yang telah atau akan menyerang secara negatif, akibat dari kurang kepercayaan, keterbukaan dan perasaan kesukuan yang berlebihan, dimana satu dengan yang lainnya tidak berusaha untuk saling mengerti dan memahami. Hal ini terjadi karena tidak dilakukan interaksi sosial dalam aktivitas bersama-sama. Interaksi sosial diperlukan guna mengoptimalkan kualitas komunikasi interpersonal yang baik kepada Anak Buah Kapal (ABK) sehingga kinerja Pelaut Wanita yang bekerja akan meningkat. Penelitian ini dibuat untuk meningkatkan kemampuan dan kecakapan dalam melakukan komunikasi interpersonal yang baik dan efektif sebagai pelaut wanita. Peneliti menggunakan metode penelitian kualitatif dengan metode pengumpulan data observasi, wawancara, dan studi pustaka.

В последние десятилетия наблюдается интенсивный рост морской торговли и увеличение объёмов морских грузоперевозок, которые привели к развитию соответствующей береговой инфраструктуры. Развивающиеся морские порты в ряде случаев становятся центрами экономического роста прибрежных территорий. Из-за локализации негативных экологических факторов в портовом регионе особое значение приобретают проблемы обеспечения экологической безопасности и устойчивого развития. Одним из эффективных методов снижения техногенного воздействия на экологию является замещение ископаемых видов топлива возобновляемыми источниками энергии, обеспечивающими электроэнергию для портовых операций и берегового питания морских судов. Однако для устьевых портов, как правило, характерны ограниченность территорий и пониженный потенциал возобновляемых ресурсов, в частности ветроэнергетики, в виду удаленности от прибрежных морских территорий. В статье на примере Калининградского морского торгового порта рассмотрены вопросы использования возобновляемых источников энергии для целей электроснабжения. Дана оценка потенциала солнечной и ветроэнергетики. Выполнен анализ системы электроснабжения порта и даны рекомендации по внедрению систем распределенной генерации на основе возобновляемых источников энергии.
Recent decades have shown rapid growth of maritime trade and an increase in sea freight volumes, which led to the development of coastal infrastructure. Developing seaports in some cases become centers of economic growth in coastal areas. Due to the localization of negative environmental factors in the port region, problems of ensuring environmental safety and sustainable development are of particular importance. One of the effective methods to reduce the technogenic impact on the environment is the replacement of fossil fuels with renewable energy sources that provide electricity for port operations and onshore power supply of ships. However, estuarine ports have limited territories and a reduced potential of renewable resources, in particular wind energy, due to the remoteness from coastal marine territories. The article examines the use of renewable energy sources for power supply using the example of the Kaliningrad Sea Trade Port. An assessment of the potential of solar and wind energy is given. The analysis of the power supply system of the port was carried out and recommendations were given for the implementation of distributed generation systems based on renewable energy sources.

В статье рассматриваются актуальные вопросы оценки рисков в работе рыбопромыслового флота. Определен состав основных технических и технологических рисков, а также рискообразующих факторов и причин, оказывающих негативное влияние на работу рыбопромыслового флота. Так, в число рискообразующих фактов входят: природные (штормы, ураганы, цунами, низкие температуры), техническое состояние судов, уровень технического оснащения рыболовных судов рыбопоисковой аппаратурой и спутниковыми системами и др. Риски в деятельности рыбопромыслового флота в основном взаимосвязаны. В этой связи при количественной оценке агрегированной величины всех рисков в работе рыболовного флота необходимо учитывать уровень взаимозависимости рисков и их коэффициент корреляции. Предложена методика расчета агрегированной оценки совокупного риска в работе рыбопромыслового флота. Приводится демонстрационный числовой пример практической реализации методики. Отмечается необходимость создания компьютерной программы реализации методики, что позволит выполнять весь комплекс расчетов агрегированных оценок совокупных рисков и эффективности мероприятий по снижению уровня рисков, а также цены риска.
The article discusses topical issues of risk assessment in the work of the fishing fleet. The composition of the main technical and technological risks, as well as risk-forming factors and causes, which have a negative impact on the operation of the fishing fleet, has been determined. So, the facts include: natural (storms, hurricanes, tsunamis, low temperatures), the technical condition of ships, the level of technical equipment of fishing vessels with fish-finding equipment and satellite systems. The risks in the activities of the fishing fleet are mainly interrelated. In this regard, when quantifying the aggregate value of all risks in the operation of the fishing fleet, it is necessary to take into account the level of interdependence of risks and their correlation coefficient. A method for calculating the aggregate assessment of the total risk in the operation of the fishing fleet is proposed. A demo numerical example of the practical implementation of the technique is given. The need to create a computer program for the implementation of the methodology is noted, which will allow performing the whole complex of calculations of aggregated assessments of total risks and the effectiveness of measures to reduce the level of risks, as well as the price of risk.
