Amaç -Çalışanlar örgüt içinde farklı nedenlerle kendi sosyal ağlarını oluşturmaktadırlar. Bu ağlar çalışanların motivasyonlarını ve performanslarını olumlu yönde etkileme potansiyeline sahip olduğu gibi, dışlanan çalışanlara ve örgüt için zararlı olabilecek davranışlara yol açma potansiyeline de sahip olabilir. Belli bir gruba dahil olamayan kişilerin olumsuz duygu durumuna gireceği ve bu durumun da örgütsel sapma davranışını kaçınılmaz kılacağı düşünülmüştür. Buradan hareketle;bireylerin iş yerindeki sosyal ağ nedenleri, ağın dışında kaldıklarındaki duygu durumları ve bu sosyal ağlardaki ilişkilerin işe nasıl yansıdığını araştırmak çalışmanın amacını oluşturmaktadır. Yöntem -Bu amaç doğrultusunda amaçlı ve kolayda örneklem yöntemi kullanılmıştır. Yüz yüze derinlemesine görüşmeler yapılarak veriler toplanmıştır. Verilerin analizinde tümevarımsal analiz yöntemi kullanılmıştır. Bulgular -Elde edilen analizler sonucunda, katılımcıların sosyo-kültürel özelliklerinin (yaş, medeni durum, eğitim durumu ve aylık gelir) sosyal ağ kurma ve örgütsel sapma davranışlarında farklılıklara sebep olduğu ve ağın dışında kalan bireyin gösterdiği sapma davranışında özellikle olumsuz duygu durumunun etkili olduğu tespit edilmiştir. Araştırma sonucunda ek olarak katılımcılarınsapma davranışları sırasıyla; politik davranışla ilgili sapma, üretim ile ilgili sapma, mülkiyetle ilgili sapma, kişiselsaldırganlıkdavranışında sapmada görülmüştür. Tartışma –Sosyal ağların örgütsel sapma üzerindeki etkisinde olumsuz duygu durumu önemli rol oynamaktadır. Otel yöneticileri ağın dışında kalan iş görenlerin duygu durumlarını anlamalı ve örgüt içinde duygu ve davranış bozukluklarına sebep olabilecek her türlü iletişim şekline, yönetici davranışlarına ve yönetsel süreçlere özellikle dikkat etmeli ve çözüm önerileri geliştirmelidir. Çalışanların olumsuz duyguları fark edildiğinde ve gerekli tedbirler alındığında, çalışan sapma davranışının önüne geçilmiş olunacaktır.

Published: July 2024

Aim: This study aimed to report the perioperative outcomes of off-clamp robot-assisted partial nephrectomy (RAPN) for multiple ipsilateral renal tumours at our Institution.

Methods: Data of consecutive patients affected by multiple ipsilateral renal tumours managed by RAPN between September 2018 and June 2023 were retrospectively analysed. Perioperative and post-operative data were collected. Eventual intra- and post-operative complications with or without readmissions (occurred within 30 days) were recorded and classified according to Clavien-Dindo system. Final pathology examination of excised tumours was performed.

Results: Twelve patients were included in the analysis. Median tumour size was 34 mm and median R.E.N.A.L. [(R)adius (tumour size as maximal diameter), (E)xophytic/endophytic properties of the tumour, (N)earness of tumour deepest portion to the collecting system or sinus, (A)nterior (a)/posterior (p) descriptor and the (L)ocation relative to the polar line] score was 6. Median console time was 134 min. An off-clamp approach with pure enucleation was possible in 20 out of 28 lesions (71.4%). Median estimated blood loss was 200 mL. No differences were observed in renal function both at discharge and after 30 days, with respect to baseline. No intraoperative complications were recorded. Post-operative complications occurred in two patients, both classified as Clavien-Dindo grade 2. Positive surgical margins were reported in one case (4.5%). No local recurrence or metastasis were diagnosed within a median follow-up of six months.

Conclusion: Our case series showed the feasibility of off-clamp RAPN in patients with multiple ipsilateral renal tumours in experienced hands. Further studies with larger sample size and longer follow-up are warranted to better define the optimal management strategy in such an uncommon scenario.

Authors: Yaman Merve , Aydın Tayfun , Pala Osman
Published: July 2024

Ranula cyst is one of the most common pathologies of the sublingual salivary gland. It is formed as a result of damage to the gland ducts and is a retention cyst filled with mucus. Methods such as drainage, excision or cryosurgery are used in the treatment. During surgical treatment, it may cause various dysrhythmias due to its anatomical relationship with the vagus nerve. In this study, we aimed to present our response to arrhythmias seen during ranula cyst excision and resistant to IV administration with local lidocaine administration.

Authors: Fedorenko Myhailo , Bondarenko Oleksander
Published: July 2024

Modeling of the aeroelasticity of a straight wing for a light aircraft by the finite element method was carried out and the simulation results were verified by a binary model. The possibility of using the finite element method for modeling the aeroelasticity of a light-class aircraft is shown. A comparison of the aeroelasticity of a light aircraft wing with and without tapering was performed. The criterion for loss of wing stability during aeroelastic oscillations is the transition from a positive to a negative value of the damping coefficient in the wing-air system at a certain flight speed. Measures to strengthen the wing structure in order to ensure the necessary flight speed are indicated.

Neural network algorithms as the cutting edge of self-organization processes
Authors: Smolin Vladimir Sergeevich
Published: July 2024

With the creation of strong AI, not only humanity, but the entire life evolution enters a new era. Life, as the most complex and most amazing self-organization process, is difficult to accurately describe, but attempts to identify the basic conditions for its development have been made for a long time ago. As it became clear about 70 years ago, the main condition for the life development is the knowledge accumulation in DNA, making it possible to reproduce life forms that have undergone evolutionary selection. Many other important conditions for the development of “living” self-organization were put forward, which were better suited as research objects than knowledge. Although with the beginning of the neural network revolution in machine learning, it became possible to study on models the processes of acquiring knowledge about the surrounding world without human participation, the researchers inertia not to include the cognition processes in self-organization studies remains. A comparison of traditional and neural network approaches to describe self-organization processes was made. Since only the neural nets describe the acquiring knowledge processes, it is concluded that neural network algorithms constitute the cutting edge of the self-organization processes development.

Spatial self-organization of a global system of industrial-trading firms
Authors: Kurakin Pavel Vyacheslavovich
Published: July 2024

I suppose a computational model for a large collective of interacting agents, where the agents resemble some industrial and trading firms. In fact, each agent or firm actually makes no difference between production and trading: anything produced is immediately ready for sale. Each agent possesses a unique set of technological skills for producing different goods. Meanwhile, some skills or products (we assume these practically the same) of different agents / firms do overlap. Next, each agent tries to increase the number of its commercial (that is, trading) links. Agents establish such links on the base of a specific pairwise coincidence of aforementioned technological skills: some-thing, which some agent produces, turns to be necessary for another one. Each agent can “see” other agents in a specific way (both locally and remotely), so the links can be established only between agents which see each other within the considered territory. The dynamics of described system leads to un-obvious effect of spatial concentrations of agents in selected locations, which we treat as “cities”. The long-term dynamics leads to both emergence and dis-appearance of cities.

Published: July 2024

The modernization of Saudi Arabia, manifested in the Arab Vision 2030 policy, has implications for various sectors of life, including the perceived modern transformation of Saudi women. Among the research on Arab Vision 2030, this article specifically focuses on elaborating the forms of transformation of Saudi women in various fields. This research uses a qualitative descriptive method that focuses on exploring literature related to women's activities and roles in the public domain after the implementation of Arab Vision 2030 and analyzing them from a modernist perspective. The results show that Arab Vision 2030 significantly impacts women's activities and roles in the public domain, especially in the socio-cultural field. This includes women's freedom to engage in public spaces, even without the presence of a legitimate companion (mahram), and without wearing a niqab or burqa. Women are also granted freedom in the fields of education, such as unrestricted choice of study programs and politics, including the permission to become politicians and hold ministerial positions, and in the economic field, with the freedom to choose careers and become corporate leaders.
THE ABRAHAM ACCORDS AND PEACE IN THE MIDDLE EAST: REGIONAL RECEPTION AND IMPLICATIONS
Authors: Sevilla Henelito Jr Arias
Published: July 2024

The normalization of ties between Israel and four Arab countries (Bahrain, Morocco, the United Arab Emirates, and Sudan) starting in 2020 through the US-facilitated Abraham Accords opened a new paradigm of peace in the greater Middle East and North African region. Optimists embrace the Accords as the harbinger of a new era of Israel-Arab relations and a renewed opportunity for peace in the region. Others consider them as mere official pronouncements by involved parties and without regard to the urgent and long-standing Israeli-Palestinian conflict. This paper argues that the Abraham Accords are based solely on the national interests of the signatories and the facilitator, the United States, and not primarily intended for restoring Israel-Arab ties and regional peace and security. This paper begins by examining the prospects and challenges of peacebuilding in the Middle East. The discussion proceeds to the pragmatism of the Abraham Accords, i.e., its strategic advantages for the signatories and the U.S. Finally, the paper briefly explores the reception of relevant actors in the Middle East and the wider Asian region, particularly Saudi Arabia, Iran, Turkey, and China.

MASS TRANSFER MODEL, SOME FEATURES OF THE TECHNOLOGY AND THE MAIN PARAMETERS OF THE APPARATUS FOR THE REGENERATION OF NITROCELLULOSE POWDERS
Authors: Anipko O. B. , Baulin D. S.
Published: July 2024

The stability of nitrocellulose plays a decisive role in determining its service life. As a result of physicochemical processes of interaction of nitrogen and its compounds with chemical elements and compounds found in the environment, nitric and nitrous acids have a negative effect on nitrocellulose. This is due to the drop in its energy value.
An analysis of the studies showed the possibility of restoring the properties of nitrocellu- lose-based powder charges by treating them with hydrogen peroxide. However, the process of regenerating powder charges on an industrial scale to obtain the best effect is not given.
Material balance equations and a molecular diffusion mass transfer model are presented. To assess the degree of hydrogen sorption by nitrocellulose, an indicator has been introduced - the reagent utilization factor. It shows what part of the peroxide of the substance for this concentration has joined the nitrocellulose.
Factors influencing the energy characteristics of nitrocellulose are presented. It has been determined that at the longest stage of the life cycle of nitrocellulose powders - the storage stage, the main factors determining the resistance of gunpowders are: their composition, the quality of the starting materials, the production method, impurities in the gunpowder, storage conditions. It is indicated what changes and processes occur in the nitrocellulose layers of powder elements.
The process of nitrogen mass transfer from the deep layers of the powder element to its surface by molecular diffusion is considered.
As part of the complex problem of operating powder charges, a mathematical model of diffusion mass transfer is considered to determine the nitrogen content depending on time and taking into account the influence of storage temperature. This model is of practical interest for creating an industrial apparatus and determining its main design dimensions and performance.
Based on the results of the experimental study, the mass transfer coefficient and the surface area involved in the regeneration process were determined.
A diagram of the technological process for regenerating nitrocellulose powder charges and the design elements of the apparatus are presented.

Authors: Ishibashi Shigeki , Shinomiya Rikuo , Hayashi Yuta , Ishikawa Masakazu , Adachi Nobuo
Published: July 2024

Case:

An 18-year-old male patient sustained a traumatic injury that resulted in the loss of approximately 50% of the radial head. Subsequently, reconstruction was performed by transplanting an osteochondral plug harvested from the lateral femoral condyle. At the 1-year postoperative follow-up, the patient was pain-free and had a good range of motion.

Conclusion:

Using a novel technique, an irreparable radial head fracture was reconstructed using an osteochondral plug from the lateral femoral condyle. Reconstruction with osteochondral plugs may be a treatment option for partial loss of the radial head.

Authors: Cahill Sean V. , Buchowski Jacob M. , Chrisinger John S.A. , Goodwin Matthew L.
Published: July 2024

Case:

A healthy, 19-year-old woman was incidentally found to have a large, destructive tumor of T11 without neurologic symptoms. Biopsy demonstrated fibrocartilaginous mesenchymoma (FCM). The patient was treated with resection including subtotal corpectomy and T8-L1 fusion with use of cage and allograft strut construct. The patient remained without recurrence over 3 years of follow-up.

Conclusion:

FCM arising from the spine is a rare tumor, of which this is the sixth report. FCM affects primarily young adults and is benign but locally aggressive, requiring complete excision to prevent recurrence.
Subdural Extra-arachnoid Hygroma Because of Occult Distal Durotomy After Minimally Invasive Decompression
Authors: Azad Tej D. , Raj Divyaansh , Srinivasan Ethan S. , Bydon Ali
Published: July 2024

Case:

We present the case of a 59-year-old man who had MIS L4-5 decompression. He presented the next day with intractable back and leg pain. Magnetic resonance imaging revealed ventral displacement of the cauda equina and a subdural collection on the right L3/L4 nerve roots. Revision decompression revealed occult durotomy caudal and contralateral to the index decompression.

Conclusion:

Minimally invasive spine (MIS) surgery leverages shorter operative time and reduced postoperative pain. Yet, decreased exposure can make identification and management complications challenging. This report highlights occult durotomy and spinal subdural extra-arachnoid hygroma in patients with postoperative nerve compression after seemingly uncomplicated MISS.

Published: July 2024

Case:

Bizarre parosteal osteocartilaginous proliferation (BPOP) is rare, especially in the foot. To the best of our knowledge, multifocal BPOP has yet to be reported. We are reporting a case of a 40-year-old woman who presented with 4 bumps over her midfoot and toes. After staging studies, we excised the lesions, and histopathology confirmed BPOP. No local recurrence was observed at the end of the 2-year follow-up.

Conclusion:

BPOP should be considered in the differential diagnosis of multiple foot bumps, whether synchronous or metachronous, which may present multifocally in the foot.
Comparative Outcomes and Failure Rates of Total Femur Replacement in Oncologic and Nononcologic Indications
Authors: Lari Ali , Esmaeil Ali , AlSalem Yousef , Alabbad Fahad , Shahin Maged , Aoude Ahmed
Published: July 2024

Background:

Total femur replacement (TFR) has become increasingly significant as a salvage procedure for both oncologic reconstruction and complex nononcologic conditions such as revision arthroplasty. Despite its effectiveness in limb salvage, TFR is associated with high complication and failure rates, which vary depending on the underlying indication.

Methods:

This systematic review and meta-analysis adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive search of MEDLINE, EMBASE, Web of Science, and Cumulative Index to Nursing and Allied Health Literature databases was conducted, focusing on studies that reported outcomes of TFR in oncologic and nononcologic cases. Primary outcomes included failure mode and rates according to the Henderson classification, functional outcomes scores, and mobility status. Data were analyzed using random-effects models and generalized linear mixed models.

Results:

A total of 35 studies involving 1,002 patients were included. The majority of TFRs were performed for oncologic reasons (63.7%). The mean Musculoskeletal Tumor Society (MSTS) score was 66%, with a limb salvage rate of 89%. The meta-analysis revealed a combined failure rate of 34%. For type 4 failures (infection), nononcologic patients exhibited a significantly higher rate at 18% (95% confidence interval [CI], 12%-26%, I2 = 46%, p < 0.01) compared with 8% in oncologic patients (95% CI, 6%-12%, I2 = 0%). Regarding combined types 1 to 4 failures, oncologic patients had a rate of 20% (95% CI, 25%-52%, I2 = 60%), whereas nononcologic patients faced a higher rate of 37% (95% CI, 12%-26%, I2 = 63%) (p < 0.05), indicating a significant difference. There were no significant differences in the MSTS score. In addition, there were no notable differences when comparing failure modes 1, 2, and 3 independently. Mobility analysis showed that approximately 70% of patients required walking aids after surgery.

Conclusion:

TFR offers a valuable limb salvage option in both oncologic and nononcologic scenarios, despite its high failure rates. Although functional outcomes were similar between groups, the higher failure rate in nononcologic cases and the poor overall quality of evidence warrant further comprehensive assessments into predictors of outcomes to optimize results.

Late Cenozoic Tectonic Evolution of the Western Nepal Himalaya: Insights from Low-Temperature Thermochronology
Authors: Harvey Jonathan E. , Burbank Douglas W.
Published: July 2024

In the central Himalaya, an abrupt physiographic transition at the foot of the Greater Himalaya (PT2) marks the southern edge of a zone of rapid rock uplift along a ramp in the Main Himalayan Thrust (MHT). Despite being traceable along ~1500 km of the central Himalaya, PT2 is less distinct in western Nepal, reflecting along-strike changes in MHT geometry and/or a migrating locus of midcrustal deformation, the details of which have important implications for seismic hazard in western Nepal. New mineral cooling ages (apatite and zircon U-Th/He and muscovite Ar-Ar) from a series of relief transects provide constraints on exhumation rates and histories in western Nepal. Inversion of these data using Pecube and QTQt models yields results that require rapid (~1.4–2.7 mm/yr) exhumation in the rocks near the along-strike projection of PT2 until around 9–11 Ma, followed by much slower (~0.1–0.4 mm/yr) exhumation until at least the late Pliocene. In contrast, transects from ~75 km hinterlandward are best fit by rapid exhumation rates (~1.5–2.1 mm/yr) over at least the past ~4 Myr. Midcrustal deformation in western Nepal is occurring well north of the position expected from along-strike structures in central Nepal, and a growing dataset suggests that rapid exhumation has been sustained there since the late Miocene. These new constraints on the late Cenozoic exhumation history of the western Nepal Himalaya provide key insight on the active structures behind the complex seismic hazards in the region.
Integrated Simulation for Microseismic Fracture Networks with Automatic History Matching in Tight Oil Development: A Field Case from Block Y2 in Ordos Basin, China
Authors: Du Xulin , Su Yanchun , Cao Renyi , Fang Maojun , Zheng Yajun , Cheng Linsong , Zhou Jinchong
Published: July 2024

The reliability of forecasts, fracture design, and recovery enhancement strategies in tight oil reservoirs is significantly compromised by the substantial uncertainties associated with fracture characterization. This article introduces an integrated simulation workflow for modeling microseismic fracture networks in tight oil reservoirs, incorporating automatic history matching, as illustrated through a field case study from block Y2 in the Ordos Basin, China. The model stochastically generates the geometry of complex fracture networks (CFNs), including parameters such as length, aperture, inclination and azimuth angles, and spatial positioning, constrained by data from hydraulic fracturing, core analyses, and microseismic monitoring. It employs a stochastic parameterization model to produce an ensemble of initial CFN property realizations and utilizes an advanced Green function-based hierarchical fracture model to accurately depict CFN morphology. The model is further refined, and its uncertainty in fracture characterization is minimized through calibration with an innovative Ensemble Kalman Filter-based assisted history-matching algorithm. Evidence suggests that this comprehensive approach effectively leverages all available geological data, substantially reduces uncertainties in the production process, and aids in identifying the optimal development strategy.

Published: July 2024

As one of the main occupational hazards, welding fumes can cause oxidative damage and induce series of diseases, such as COPD or asthma. To clarify the effects of the metal fume ultrafine particulates (MF-UFPs) of welding fumes on oxidative damage, UFPs were collected by melt inert gas (MIG) and manual metal arc (MMA) welding, and the composition was confirmed. Human bronchial epithelial 16HBE cells were treated with 0-1000 µg/cm2 MF-UFPs to analyse the cytotoxicity, oxidative stress and cytokines. The protein and mRNA expression of Keap1-Nrf-2/ARE signalling pathway components were also analysed. After 4 h of treatment, the cell viability decreased 25% after 33.85 and 32.81 µg/cm2 MIG/MMA-UFPs treated. The intracellular ATP concentrations were also decreased significantly, while LDH leakage was increased. The decreased mitochondrial membrane potential and increased ROS suggested the occurrence of oxidative damage, and the results of proteome profiling arrays also showed a significant increase in IL-6 and IL-8. The expression of AREs which related to antioxidant and anti-inflammatory were also increased. These results indicate that the MF-UFPs can cause oxidative stress in 16HBE cells and activate the Nrf-2/ARE signalling pathway to against oxidative damage.
What motivates and demotivates energy savings in times of crisis? – An argument mining analysis using X/Twitter data
Authors: Loschke Carmen Sophia , Braungardt Sibylle , Rieger Jonas
Published: July 2024

The energy crisis following the Russian invasion of Ukraine has prompted affected countries to increase efforts to save energy. Despite substantial energy conservation observed across sectors, research has inadequately explored the reasons behind these savings. This study bridges this gap by analyzing the discourse on energy conservation during the crisis in Germany, using Twitter data. We analyse a set of 136,837 tweets from January 2022 until May 2023. The analysis consists of two approaches based on natural language processing (NLP): First, we conduct word counts within the days with high tweet activity related to energy saving to identify specific triggers. For a broader quantitative analysis, we then use text classification to categorize the data set into different aspects as well as different stances and investigate how these evolve during the crisis. Our results show a heightened focus on energy conservation in the Twitter debate during the crisis, reflected in an increase of the average monthly tweets from 730 (before 2022) to 8,552 in 2022/2023. Regarding the motivations, ethical concerns linked to the war play a larger role in the initial months, while other factors such as energy costs, solidarity aspects, and climate change are consistently present throughout the debate. Additionally, we note significant negative discourse regarding the policy measures enacted during the crisis, indicating that policy backlash is a critical issue, at least in the realm of the Twitter debate. Given the vital role of energy efficiency in combating climate change, comprehending the motivations and de-motivations behind voluntary energy conservation during the crisis offers valuable insights. This understanding can inform future policies aiming to encourage energy savings.

Background
Evans syndrome(ES) is a rare autoimmune hematologic disorder defined by autoimmune hemolytic anemia and idiopathic thrombocytopenia and/or neutropenia. Little is known about its epidemiology and prognosis in different age groups. It is usually present in the elderly. The typical presentation of this syndrome involves two hematological lines, most commonly autoimmune hemolytic anemia and immune thrombotic thrombocytopenia. Here, we report a case of an infant diagnosed with Evans syndrome triplet involving the three blood cell lines.
Case Presentation:
We Present an eight-month-old male who was brought to our department with fever, jaundice, and petechial rash. He had a negative septic workup, and CBC revealed pancytopenia with severe thrombocytopenia, anemia, and neutropenia. Differential diagnoses were excluded by further tests. These included peripheral smears that showed < 10% blast cells, and bone marrow aspiration was normal. A diagnosis of Evans syndrome (ES) was made. The patient was treated with intravenous immunoglobulin and high-dose methylprednisolone, followed by oral steroids, resulting in clinical and laboratory remission.
Conclusion
This case directs us to consider Evans syndrome as a differential diagnosis in infants presenting with pancytopenia. We advocate an international database of these patients to increase awareness of any patient with suspected ES.
Using Ocean Data to Predict Monthly Air Temperatures of California's Coastal Cities
Authors: Zhang Xiaolin , Feng Ming
Published: July 2024

Air temperature anomalies in the narrow California coastal boundary layer is closely associated with the adjacent coastal sea level variability. Coastal sea levels, proxies of upper ocean heat content, are regulated by alongshore winds and poleward propagating coastal Kelvin waves. Increased upper ocean heat content or higher sea level can enhance oceanic heat release to the atmosphere which will be carried inland due to the prevailing onshore winds. Based on these physical processes, sea level anomaly (SLA) and sea surface temperature (SSTA) are combined and used as a predictor here to forecast air temperature anomaly at 4 main cities along the California coast. Results show that air temperature in these land-based stations can be predicted by SLA and SSTA with 2–3 months in advance. The prediction capability is better during late summer/early fall when the upwelling is strongest. The predicting ability is limited within a 2–3 degree narrow coastal region, and it decreases rapidly for inland stations. Our work also suggests that it is very important to enhance the resolution of models near coastal region to improve seasonal prediction.
Should we invest more in transport for lagging regions?
Authors: Cho Seongkyun
Published: July 2024

This research proves that sizable transport investment for lagging regions is reasonable, and smaller investments, such as bus route arrangements, are better for prosperous regions, given house prices or income levels. This study’s essential takeaways are as follows. First, facilitating walking accessibility to bus stations in ten minutes is preferable to economically developed regions. Second, sizable transport investments, increasing fifteen minutes of accessibility to infrastructure by public transport modes, are better for the lagging regions. Third, most industries do not have positive synergies with the two accessibilities above in developing the nationwide economy, so there might be a limit for transport investment to continue getting benefits on a long-term basis. Fourth, the incumbent test measuring the feasibility of transport investment needs to accept the secondary quantitative benefits preferable to lagging regions. Fifth, the construction industry extracted synergies with the 15-minute accessibility through public transport to most infrastructures in lagging regions. Sixth, enterprises of an industry locate themselves too densely; for example, education and interactive access to buses do not supply the power to develop the regions (e.g., Seoul) well. Seventh, this study quantifies the interactions above as the actual currencies for objective and easy comparisons. Finally, this research’s policy recommendations work for international cases harmed by regional disparity since Korea has achieved economic development in a relatively short term while producing severe economic regional disparity due to the uniform transport investment principle.
Evaluation of Different Container Types on Root Structure and Performance of Nursery-grown Citrus Plants

Health and quality of the root system are imperative to ensure the successful establishment of a citrus tree after transplant from the nursery into the field. Containerized citrus production in enclosed nurseries restricts root growth and can result in root circling and intertwining. This may hinder root expansion and result in root girdling after transplant, negatively affecting tree establishment and growth. The root structure of a transplanted citrus tree can also be affected by the container type used in the nursery. Containers with root-pruning properties like chemical pruning or air pruning reduce root circling and may produce superior root systems compared with regular, nonpruning containers. The aim of this study was to evaluate the effects of different nursery containers on root physiological and morphological traits and plant performance over 15 months of growth in the nursery. Three container types, chemical pruning containers, air-pruning containers, and standard nursery containers, were compared. The chemical pruning containers were standard citrus nursery containers with a mixture of copy hydroxide [Cu(OH)2] and copper carbonate (CuCO3) [10% copper (Cu)] applied to the inner wall. Pruning occurs upon contact of the roots with the Cu on the wall of the containers. The air-pruning containers were custom-sized Air-Pots in which pruning occurs on holes in the wall of the containers upon contact of the roots with the air. Two rootstocks, US-812 and US-942 (Citrus reticulata × Poncirus trifoliata), were included for comparison in the nongrafted stage and 12 months after grafting with ‘Valencia’ orange (Citrus sinensis). Chemical root pruning positively influenced tree height, shoot mass, leaf area, rootstock trunk diameter, and the nonfibrous root biomass. No differences among container types were observed for the fibrous root biomass, but chemical pruning produced more roots that were finer with a higher specific root length and a higher respiration rate. In contrast, air pruning produced more roots that were thicker compared with the other containers. Most of the leaf nutrients were lower in trees grown in the chemical pruning containers compared with the standard containers, except for Cu and zinc (Zn), which were highest in the former. Trees growing in air-pruning containers were not significantly different in growth from trees growing in standard containers.

Medical institutions have implemented academic mentoring programmes to support students in navigating learning disruptions caused by the COVID-19 pandemic. However, the strategies academic mentors employ to assist students in this context remain unexplored. This study utilised a qualitative approach and conducted in-depth interviews with 17 preclinical students and eight mentors who participated in mentoring sessions during the pandemic. The participants were selected using purposive stratified sampling. The data were analysed using a modified grounded theory approach (M-GTA). A total of 24 concepts, eight categories, and two core categories were generated from the data analysis. The primary goal of mentoring is to empower students to adapt to learning disruptions independently. Mentors play academic parenting roles and serve as mediators. Strategic steps in mentoring sessions involve monitoring students’ adaptability, identifying their potential, and encouraging them to determine new learning strategies tailored to changing learning environments. Several enabling factors contributed to the programme’s success, including responsive mentors, acknowledging individual challenges, and offering tailored mentorship; students with effective communication skills and proactivity; and a robust mentoring system equipped with a well-structured curriculum, technology-enhanced mentorship, and regular faculty development. To better prepare students for potential disruptions, this study recommends integrating the development of adaptability skills into the mentoring programme curriculum.

Crystallization induced by heterogeneous surfaces is an important process in geochemistry, biomineralization, and material synthesis, but the effects of heterogeneous surfaces on the transformation of metastable phases into new crystals remain poorly understood. In this work, we studied the transformation behaviors of ferrihydrite (Fhy) in the presence of hematite (Hem) nanoplates with specific exposed facets ({001} and {113}) at different pH (4, 7, and 12). Our results reveal that the Hem nanoplates can induce the transformation of Fhy to Hem/Gth (goethite) and accelerate the transformation rate. This effect is primarily achieved by modulating the dissolution-recrystallization process, i.e., accelerating the dissolution of Fhy and promoting the heterogeneous crystallization (to form new Hem/Gth) at the surface of added Hem nanoplates, and solution pH plays crucial roles in these processes. In specific, a relatively low supply of dissolved Fe3+ from Fhy at pH 4 favors island growth of new Hem at the {001} facets of Hem nanoplates and layer-by-layer growth at the {113} facets, which eventually results in the formation of thermodynamically stable pseudo-cubic morphology (exposing {012} facets). Because of the very low solubility of Fhy at pH 7, the induced transformation of Fhy by Hem nanoplates is rather weak. While at pH 12, a high supply of dissolved Fe3+ from Fhy benefits the layer-by-layer growth at {001} facets of Hem and the significant heteroepitaxial growth of Gth at the {113} facets. Besides the induced transformation, the direct solid-state transformation of Fhy into Hem and the homogeneous crystallization of dissolved Fe3+ also contribute to the transformation of Fhy. This study, for the first time, well reveals the mechanisms of induced transformation of Fhy in the presence of Hem nanoparticles, which will advance our understanding of the significant effects of heterogeneous surfaces in modulating the transformation of metastable phases, and supplement the transformation mechanisms of Fhy.
