Authors: Гомзяков М.В. , Соболенко А.Н. 
Published: December 2021

В работе содержится обзор отказов главных силовых установок на судах торгового и рыболовного флота, осуществляющих деятельность в дальневосточных морях с целью установления основных факторов, способствующих возникновению аварии. Решение таких задач, как анализ актов расследования экспертами морских происшествий с отказами судовых технических средств, в первую очередь главных двигателей, применительно к соблюдению судомеханиками обязательных нормативных требований, позволяет эффективнее выявлять проблемы безопасности мореплавания. Нормативно-правовая дисциплина судовой технической службы относится к недостаточно исследованным факторам, влияющим на поломки судовой техники. Ретроспективный анализ ошибочных действий или бездействия судового персонала необходим для выработки мер по снижению аварийности. Одним из перспективных подходов представляется индексация аварий, гармонизированная с действующей в морской отрасли системой кодов.
The paper provides an overview of the failures of the main power plants on ships of the merchant and fishing fleets operating in the Far Eastern seas in order to establish the main factors contributing to the occurrence of the accident. The solution of such problems as the analysis of acts of investigation by experts of marine accidents with failures of ship technical equipment, primarily of the main engines, in relation to the observance of mandatory regulatory requirements by ship mechanics, makes it possible to more effectively identify problems of safety of navigation. The regulatory and legal discipline of the ship's technical service is one of the insufficiently studied factors affecting the breakdown of ship equipment. Retrospective analysis of erroneous actions or inaction of shipboard personnel is necessary to develop measures to reduce accidents. One of the promising approaches is the indexing of accidents, harmonized with the current code system in the maritime industry.

Представлена методика подбора центробежного сепаратора для комбинированных систем тонкой очистки моторного масла в двигателях внутреннего сгорания. Предложен показатель (индекс производительности сепаратора), который характеризует интенсивность разделения гетерогенных систем центрифугированием. Показана зависимость скорости изнашивания основных деталей дизеля от качества используемых горюче-смазочных материалов и интенсивности очистки масла (индекса производительности сепаратора). Рассмотрены преимущества комбинированной системы очистки смазочного масла, включающие в себя центробежный сепаратор, обеспечивающий очистку масла от нерастворимых загрязнений мелкодисперсной фазы работающий совместно с саморегенерирующимся фильтром. Благодаря такому сочетанию обеспечивается минимальной изнашивание пар трения дизеля. Преимущество данного метода очистки также заключается в возможности обеспечения автономной работы механизмов смазочной системы при сохранении высокой эффективности очистки. С помощью экспериментального моделирования определено минимальное значение индекса производительности центробежного сепаратора, необходимое для стабилизации изнашивания деталей дизеля и достижения ресурсосберегающего маслоиспользования. Проиллюстрировано сравнение результатов моделирования с экспериментальными данными.

В работе на основе базы данных температуры поверхности воды в северной части Тихого океана на климатическом масштабе 1980 - 2019 годы с временным шагом один год исследована зависимость скорости изменения температуры от широты. В летний (август) период отмечается устойчивая зависимость темпов роста средней зональной температуры поверхности в направлении от тропиков к субарктике. Характерная скорость роста температуры в тропических широтах 0,011 0C/год, в субтропиках 0,021 0C/год, в субарктических акваториях выше 400N имеем 0,027 0C/год. В зимний сезон (февраль) такой тенденции не наблюдается. Представлены количественные оценки возможного влияния температурных трендов на глобальную циркуляцию. Рост поверхностной температуры увеличивает вертикальную стратификацию и уменьшает вертикальный обмен вод, относительное ослабление вертикальной скорости не превышает 0,01 % за десятилетие, что представляет незначительным. Представлена количественная оценка уменьшения геострофической составляющей горизонтальной скорости течения продолжения Куросио на восток вследствие климатического сглаживания перепада температуры воды южнее и севернее струи.
The change of sea surface temperature (SST) in the North Pacific Ocean on the climatic scale 1980 - 2019 is considered. The rate of temperature change as a function of latitude with the one year time step and the 10 degrees spatial step is investigated. The latitudinal time series for summer and winter are separated. The summer (August) period has the climatic stable dependence of the surface temperature growth rate in the direction from the tropics to the subarctic area. The characteristic rate of temperature rise in tropical latitudes is 0.011 0C / year; in the subtropics is 0.021 0C / year; in subarctic waters above 40 0N this is 0.027 0C / year. The winter season (February) does not have this tendency. The quantitative estimates of the temperature trends influence on global circulation are presented. The SST growth enhances vertical stratification and decreases the vertical water exchange. The estimation of the relative vertical speed decrease is not more than 0.01% / decade. The quantitative assessment of the weakening of the geostrophic horizontal velocity in the Kuroshio extension due to the climatic smoothing of the SST south - north gradient is presented.

O artigo foi construído a partir dos resultados da pesquisa realizada no âmbito do Programa de Pós-graduação em Desenvolvimento Regional da UTFPR - Campus de Pato Branco, entre os anos de 2020 e 2021. O objetivo é analisar como as famílias agricultoras do município de Ampere, no sudoeste do Paraná, compreendem a relação da sua produção de alimentos destinada ao autoconsumo com a Segurança Alimentar e Nutricional. A pesquisa qualitativa foi realizada por meio de entrevistas com famílias agricultoras que revelaram a diversidade de situações produtivas e socioeconômicas do município (10 famílias), com base em formulário semiestruturado e registro em diário de campo. A produção de autoconsumo para essas famílias tem relação com a qualidade do alimento, saúde, tradição/cultura, economia e afetividade. Os alimentos por eles/elas produzidos são valorizados por possuírem uma qualidade nutricional superior aos alimentos comprados, pela confiança no saber-fazer tradicional e na ausência de agrotóxicos, retratando uma segurança ontológica. A produção de autoconsumo é, também, um elemento capaz de fortalecer o vínculo da família com o lugar em que vive e de dar continuidade à sua tradição em produzir alimentos para a família, assumindo um papel de resistência a partir da reflexividade que incorpora a crítica aos alimentos/produtos industrializados, em especial os ultraprocessados, mesmo quando, por vezes, fazem parte de compras destinadas às crianças, ao mesmo tempo procuram manter seu modo de viver – do plantar, colher e consumir seu próprio alimento –, o que denota maneiras de se manterem seguros frente às incertezas e riscos dos alimentos “modernos”.
Työuupumuksesta toipumisen yksilölliset polut

Published: December 2021

Tutkimuksen tarkoituksena oli selvittää työuupumuksesta toipumisen kehityspolkuja ja näihin yhteydessä olevia tekijöitä 1,5 vuoden seurannan aikana. Erityisenä kiinnostuksen kohteena oli toimijuus ja sen rakentumisen yhteys työuupumuksesta toipumiseen. Tutkimusaineisto koostui Kuntoutus Peurungan Virveli-kuntoutuskursseille osallistuneista ja kuntoutuksesta lähtökohtaisesti hyötyneistä henkilöistä (n = 9). Kyseessä on tapaustutkimus, jossa näiden henkilöiden toipumisprosessia tutkittiin monipuolisesti sekä haastattelun että kyselyiden avulla. Tulokset osoittivat, että monet työympäristöön liittyvät tekijät olivat yhteydessä toipumisprosessiin, mutta ne eivät yksinään selittäneet sitä, oliko henkilöiden työuupumus uusiutunut vai ei. Aineistosta löydettiin kolme erilaista kehityspolkua, jotka olivat ”työuupumuksesta toipuneet”, ”uudestaan uupuneet” ja ”kovia kokeneet, mutta positiiviseen keskittyvät”. Kuntoutujien toipumispolkuun näyttäisi tämän tutkimuksen perusteella olevan yhteydessä heidän kokemansa henkilökohtainen toimijuus, joka ilmeni erityisesti uskona omaan pärjäämiseen kuntoutusjakson lopussa. Näihin tekijöihin olisikin hyvä kiinnittää huomiota sekä jatkotutkimuksissa että työuupumusinterventioiden kehitystyössä, jotta kuntoutuksen vaikuttavuutta voitaisiin tehostaa.
Abstract
The individual recovery paths from job burnout: a mixed methods case study on the long-term impact of a rehabilitation intervention
The purpose of this study was to examine the developmental paths of burnout recovery and factors associated with it during a 1.5-year follow-up period. A special interest of the study was in agency and whether it is connected to burnout recovery. The study sample (n = 9) included people, who had benefitted from a rehabilitation period arranged earlier in Peurunka Rehabilitation Centre. This research was a case study, which was basedon data collected by interviews and questionnaires in analyzing the recovery process of the participants. Analysis showed that many job-related factors were connected to the recovery process, but none of them was able to explain alone whether participants’ burnout had relapsed or not. Three different recovery paths were found among the sample: ”recovered participants”, ”relapsed participants” and ”participants with difficult experiences but positive mindset”. The results indicate that the personal agency of the people participating in rehabilitation is connected to their recovery paths. Agency was manifested, for example, in participants’ self-efficacy estimates at the end of the rehabilitation period. These factors should be paid more attention in future studies as well as in developing burnout interventions in order to improve the effectiveness of burnout rehabilitation.

Published: December 2021

Abstract
Based on observations with the IRAM 30 m and Yebes 40 m telescopes, we report evidence of the detection of Milky Way–like, low-excitation molecular gas, up to the transition CO(J = 5–4), in a distant, dusty star-forming galaxy at z
CO = 1.60454. WISE J122651.0+214958.8 (alias SDSS J1226, the Cosmic Seahorse), is strongly lensed by a foreground galaxy cluster at z = 0.44 with a source magnification of μ = 9.5 ± 0.7. This galaxy was selected by cross-correlating near-to-mid-infrared colors within the full-sky AllWISE survey, originally aiming to discover rare analogs of the archetypical strongly lensed submillimeter galaxy SMM J2135–0102, the Cosmic Eyelash. We derive an apparent (i.e., not corrected for lensing magnification) rest-frame 8–1000 μm infrared luminosity of

We consider different scenarios to reconcile our observations with typical findings of high-z starbursts, and speculate about the presence of a previously unseen star formation mechanism in cosmic noon submillimeter galaxies. In conclusion, the remarkable low line luminosity ratio r

The purpose of this research is to measure the motivation of nursing students, option: multi-skilled nurse (n=58), following their participation in an e-learning activity in the form of formative quizzes. The pedagogical scenario was based on Keller's ARCS motivation model.
Data were collected through the IMMS questionnaire adopted from the ARCS model.
The results show that the students were motivated by the e-learning activity (mean score = 4.22±, 51091), and that the motivation variables studied correlated positively with the overall motivation score (p-value < .001).
Through this research, it was found that an instructional scenario based on the ARCS model had a positive impact on students' motivation for e-learning, thus encouraging allied health educators to design educational tools that can motivate nursing students.

Published: December 2021

The IoT is a growing new approach that has been defined as a global network of devices and machines capable of reliably communicating with each other without human intervention. It is one of the essential technologies in any field, such as medicine and attracts great attention in the future. It is applied in several areas that have achieved success. However, the power and the addition of connected objects to technology is based on the fact that its objects can establish several tasks: communicate, analyze, process and manage data in a parallel manner, which is very difficult in terms of energy consumption. Therefore, the problems related to consumption slow down considerably the evolution and the fast deployment of this high technology.Therefore, it is necessary to create a new lightweight and robust mechanism, which ensures the minimization of the consumption of the objects and makes these objects efficient and less costly while being adapted to the capacities of objects and technologies.That is why our paper aims to address this significant problem and present the role of energy consumption, which is essential in deploying successful IoT products and services and presenting the IoT categories for applications. First, we propose a method that minimizes energy consumption and meets our need through three essential steps: firstly, to study the existing methods to minimize energy consumption. Next, based on these methods, we create a new concept using the data flows. Finally, we implement our solution in an intelligent parking lot to carry out our approach and describe our design steps and conclude with the result of our study and make an interpretation that summarizes our work.

Association between transcranial Doppler vasospasm and functional outcome after subarachnoid hemorrhage
Authors: Majewska Paulina , Hara Sozaburo , Gulati Sasha , Solheim Ole 
Published: December 2021

AIM OF THE STUDY:
This study aimed to investigate the association between transcranial Doppler (TCD) vasospasm and patient outcome and to assess the predictive factors for developing TCD vasospasm after subarachnoid hemorrhage (SAH).

MATERIALS AND METHODS:
This retrospective observational study included adult patients with nontraumatic SAH. Patient characteristics and TCD values were recorded retrospectively from patient records. Data on maxTCD (maximal TCD value recorded on any side between day 1 and day 14) as well as Δ TCD (maximal difference between mean velocity measured on days 1–3 and days 4–14 on any side) were calculated. The modified Rankin Score was recorded from electronic patient notes at discharge and 3, 6, and 12 months after ictus. The effect of TCD vasospasm, maxTCD, and Δ TCD on the clinical outcome was investigated. Potential predictive factors for developing TCD vasospasm were assessed. The association between the same factors and maxTCD and Δ TCD were explored.

RESULTS:
One hundred and thirty-eight patients were included in the study. Higher age was associated with a lower risk of developing TCD vasospasm (odds ratio: 0.952, 95% confidence interval: 0.924–0.982, P = 0.002). Fisher grade was a predictor of developing TCD vasospasm (P = 0.05). Age was negatively correlated with maxTCD (R = −0.47, P = 0.01). There was no statistically significant difference in patient outcome at hospital discharge and at 3, 6, and 12 months between patients with and without TCD vasospasm. Higher maxTCD and Δ TCD were associated with a worse clinical outcome at 3 months after SAH ictus.

CONCLUSIONS:
The clinical benefit of routine TCD assessments in SAH patients remains uncertain.

Published: December 2021

Background and Aim:
The complete sealing of the pulpal space contributes to the better healing potential after an root canal treatment, and root canal sealers are an integral part of this treatment which comes in contact with the periodontal tissue. Biocompatibility of an endodontic sealer plays an important role in the root canal treatment procedure. Hence, the aim of the study was to compare and evaluate the cytotoxicity and genotoxicity effect of three resin-based sealers on human periodontal fibroblast cells.

Settings and Design:
This in vitro study was conducted in Dr. Prabhakar Kore's Basic Science and Research Center and K. L. E V. K. Institute of Dental Sciences, Belagavi.

Materials and Methods:
Human periodontal fibroblasts were incubated with 15 specimens of Group 1 – AH Plus Group 2 – MTA Fillapex, and Group 3 - GuttaFlow 2, respectively. Cytotoxicity was assessed by 3,(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and genotoxicity was assessed by Comet assay at time intervals at 24 h and 48 h.

Statistical Analysis:
Data were analyzed by the Kruskal–Wallis and Mann–Whitney U-test.

Results:
AH Plus and GuttaFlow 2 did not show any cytotoxicity or genotoxicity. MTA Fillapex was slightly cytotoxic throughout the time interval, and it also showed low genotoxicity throughout the time periods for which it was tested.

Conclusion:
AH Plus and GuttaFlow 2 did not show any cytotoxic and genotoxic effect; however, MTA Fillapex showed cytotoxic and genotoxic effect throughout the time interval.
Comparative Evaluation of Efficacy between Recombinant Human Bone Morphogenetic Protein-2 Impregnated with Absorbable Sponge and Platelet-Rich Fibrin in the Treatment of Grade II Furcation Defects
Authors: Sneha Kidambi , Sowjanya Kacharla , Vaishnavi Varanasi , Chandra Rampalli Viswa 
Published: December 2021

Aim and Objectives:
The objective of the study was to clinically and radiographically compare and evaluate the regenerative potential of recombinant human bone morphogenetic protein-2 (RhBMP-2) impregnated with absorbable collagen sponge and platelet-rich fibrin (PRF) in the treatment of Grade II furcation defects.

Patients and Methods:
Thirty-two subjects were randomly assigned to each of the following groups: bone morphogenetic protein (BMP) group and PRF group, with one defect/subject. Sixteen Grade II furcation defects were treated with RhBMP-2 impregnated with absorbable collagen sponge in the BMP group and the remaining 16 defects were treated with PRF in the PRF group. Clinical and radiographic parameters which were evaluated at baseline, postoperative 1 week, 3 months, and 6 months were probing pocket depth, clinical attachment level, scoring of plaque index, and gingival index, and the bone fill was evaluated using Digital Subtraction technique and morphometric area analysis with ImageJ® software.

Results:
RhBMP-2 in absorbable collagen sponge was effective in increasing the bone fill in Grade II furcation defects when compared to PRF alone (P = 0.05). In relation to clinical parameters, both the groups showed no statistical significance between them.

Conclusion:
The unique regenerative potential of RhBMP-2 impregnated with absorbable collagen sponge makes it a potential agent to be used as a graft material for the treatment of Grade II furcation defects.
