Published: February 2024

Abstract

Technological innovation has emerged as a vital strategic resource in recent years in the context of global economic and technological competition. This study adopts an innovation systems approach to assess the efficiency of technological innovation in China from 2011 to 2021 by using the network DEA-based model of efficiency. The results show that the overall average efficiency in the region exhibited a modest upward trend, with notably significant increases observed in Beijing, Heilongjiang, and Shaanxi. The average efficiency of commercialization of R&D in the 30 provinces of China ranged from 0.68 to 0.81 from 2011 to 2021, and improved in the provinces of Jilin, Qinghai, Jiangxi, Inner Mongolia, Hainan, Tianjin, Xinjiang, and Zhejiang. The average efficiency of resource backflow had a W-shaped trend. Beijing was consistently efficient in resource backflow throughout the study period according to the DEA. On the contrary, the efficiency of resource backflow in Liaoning, Chongqing, and Xinjiang was relatively low.

Published: February 2024

Abstract

Estimating the states of chaotic cellular automata (CA) based on noisy imperfect data is challenging due to the nonlinearity and discreteness of the dynamical system.This paper proposes particle filter (PF)-based data assimilation (DA) for three-state chaotic CA and demonstrates that the PF-based DA can predict the present and future state even with noisy and sparse observations.The chaotic CA used in the present study comprised a competitive system of $land$, $grass$, and $sheep$.To the best of the authors' knowledge, this is the first application of DA to chaotic CA.The performance of DA for different observation sets was evaluated in terms of observational error, density, and frequency, and a series of sensitivity tests of the internal parameters in the DA was conducted.The inflation and localization parameters were tuned according to the sensitivity tests.
Habitat prevails over host sex in influencing mycobiome structure of terrestrial isopod, Armadillidium vulgare
Authors: Yang Jiho , Cha Yehyeon , Oh Seung-Yoon 
Published: February 2024

Abstract

The terrestrial isopod, a crustacean order that has successfully transitioned from aquatic to land ecosystem, functions as a soil bioengineer and plays a crucial role in ecological decomposition. While there has been comprehensive documentation of bacterial associations with isopods, suggesting their contribution to digestive processes, the fungal component of isopods remains a less-explored dimension. Expanding our fundamental exploration into terrestrial isopods, we investigated whether the fungal community in Armadillidium vulgare is more significantly influenced by host sex or habitat using high-throughput sequencing-based internal transcribed spacer region amplification. Our findings revealed that the isopod mycobiome structure and taxonomic composition are predominantly shaped by the host's habitat rather than its sex. While the fungal richness of the mycobiome varied based on isopod sex, the co-occurrence network exhibited distinct variations dependent on both habitat and host sex. Finally, we observed a complete overlap of core mycobiomes based on isopod sex and identified fungal residents that are consistently distributed in a manner specific to either the habitat or host sex. In conclusion, we assert that community assembly of the isopod mycobiome in an untouched ecosystem is more significantly influenced by location than sex. We contend that this offers a fundamental groundwork, laying the cornerstone for future investigations into terrestrial isopods — pivotal agents in ecological decomposition within ecosystems.

Authors: ValizadehKaji Babak , Mohammaei Mohsen 
Published: February 2024

Abstract

Background: In the present research, the effects of foliar application of seaweed extract, fulvic acid, and potassium silicate on leaf mineral contents, chlorophyll content, fruit yield, and quality, as well as physiochemical attributes of ‘Page’ mandarin fruits were evaluated.
Results: Leaves of trees fed with seaweed extract, fulvic acid, and potassium silicate accumulated greater concentrations of N (15.09–22.16%), P (20–120%), K (17.02–46.80%), Ca (1.69–32.76%), Mg (26.31–84.21%), Zn (199.87–261.76%), Mn (79.92–139.04%), and Fe (59.12–148.65%) than those unfed. Mandarin trees fed with the nutrient solutions, especially seaweed extract, had higher chlorophyll a (10.61–29.20%) and total chlorophyll (8.75–24.37%) contents. Applying the nutrient solutions, especially seaweed extract, increased yield (23.86–48.87%), fruit juice (7.86–16.35%), and firmness (3.47–19.58%), but reduced the pulp (23.16–39.64%) of fruits. Moreover, fruits of mandarin trees fed with the nutrient solutions and especially seaweed extract showed a greater level of total soluble solids (TSS) (26.03–41.58%), total soluble solids/titratable acidity (TSS/TA) (16.99–32.70%), color index L* (5.68–10.88%), color index a* (54.07–100.90%) and color index b* (30.02–58.80%), vitamin C (41.04–84.84%), total phenol (26.76–64.78%), carotenoid (130.76–167.92%), antioxidant activity (3.56–12.87%), as well as the activity of guaiacol peroxidase (GPX) (12.03–44.39%) and catalase (CAT) (26.92–53.84%), ascorbate peroxidase (APX) (77.81–103.34%), and superoxide dismutase (SOD) (11.32–38.36%) enzymes.
Conclusion: The study findings evidenced that foliar application of seaweed extract, fulvic acid, and potassium silicate has a high potential for improving fruit yield and quality of mandarin.

Authors: Orban Emese , Pap Zsuzsanna , Sipos Remus Sebastian , Fechete Radu 
Published: February 2024

Abstract
Introduction.
Bone is a complex tissue that fulfils the role of a resistance structure. This quality is most commonly assessed by bone densitometry, but bone strength may not only be related to bone mineral density but also to the preservation of bone cytoarchitectonics.
Material and methods.
The study included two groups of rats, ovarectomized and non-ovarectomized. Each group was divided into three batches: control, simvastatin-treated and fenofibrate-treated. In the ovarectomized group, hypolipidemic treatment was instituted at 12 weeks post ovarectomy. One rat from each of the 6 batches was sacrificed 8 weeks after the start of treatment in the group. The experimental study was performed using a Bruker Minispec mq 20 spectrometer operating at a frequency of 20 MHz, subsequently also performed by 1H T2-T2 molecular exchange maps.
Results.
The results were represented by T2-T2 molecular exchange maps that showed, comparatively, both pore size and their interconnectivity at the level of the posterior femoral epiphysis, being able to evaluate both the effect of estrogen on bone tissue biology and the effect of the lipid-lowering medication simvastatin and fenofibrate both in the presence and absence of estrogen.
Conclusion.
T 2-T2 molecular exchange maps showed that the absence of estrogen results in an increase in bone tissue pore size and interconnectivity. In the presence of estrogen, lipid-lowering medication, both simvastatin and fenofibrate alter bone tissue cytoarchitectonics by reducing pore interconnectivity. In the absence of estrogen, fenofibrate improves bone tissue cytoarchitectonics, the T2-T2 molecular exchange map being similar to that of non-osteoporotic bone tissue.

Abstract

Background
Immunotherapy has changed the outlook for cancer treatment. A closer look at the accompanying symptoms from the patient’s perspective is necessary to improve their tolerance to treatment and is the basis for standardized symptom management.
Objective
To describe the symptomatic experience of skin toxicity in cancer patients undergoing immunotherapy.
Design:
Qualitative interviews on symptom experiences were conducted from the perspective of cancer patients receiving immunotherapy.
Methods
A purposive sample of 18 patients with immune-related cutaneous adverse events participated in this semi-structured interview. Transcripts were entered into NVivo 11.0. Qualitative thematic analysis was used to analyze the data for significant statements and phrases, which were organized into themes and subthemes.
Results
Three main themes were identified in the data: (I) management of skin toxicity in patients; (II) patients’ experience of skin toxicity; and (III) problems that skin toxicity poses for patients and the support they would like to receive.
Conclusions
The result enables nurses to better understand and empathize with the patient’s experience, to truly practice the essence of patient-centered care, and provide a basis for the development of standardized symptom management programs in the future.

Authors: MESUTOĞLU Özgül ÇİMEN 
Published: February 2024

Abstract
This study endeavours to quantify the water footprint of academic and administrative personnel at Konya Technical University. Water footprint assessment, a critical metric for evaluating human impact on water resources, is increasingly recognized as a vital aspect of sustainable resource management. The research involves surveying participants on their water consumption habits, particularly focusing on preferences related to food and sugar intake. Preliminary findings indicate diverse responses in terms of food preference, with a majority favouring low intake. Likewise, the survey reveals varying patterns in sugar and sweets consumption, shedding light on the frequency and extent of such practices. By systematically analysing the water footprint within the university community, this study contributes to a broader understanding of water resource utilization and offers insights for sustainable practices in academic and administrative settings. The study aimed to determine the water footprint of the campus in relation to personal consumption behaviours by asking the questions in the "Water Footprint Network (WFN)" to a total of 476 people at the campus, including both the academic and administrative staff. According to the WFN, the average water footprint of the staff was determined as 1694 m3/year.

Published: February 2024

Abstract
Background
Dietary interventions are used for the treatment of hypertension. We evaluated the cost-efficacy of delivering boxes of healthy, culturally tailored foods and checks that can only be spent on produce in a Native American population.
Methods
We conducted a group randomized controlled trial from 2018–2020 with N = 2 treatment counties and N = 2 control counties and a total of N = 160 Native American adults with baseline stage 1 or stage 2 hypertension. Participants in the intervention group received monthly boxes of food that adheres to the Dietary Approaches to Stop Hypertension diet as well as checks that could only be spent on produce for 6 months. We measured blood pressure and quality of life at baseline and at a 6-month follow-up in both intervention and control groups. We used ordered logistic regression to estimate the effect of treatment on probability of blood pressure improvements. We then conducted a cost-efficacy analysis.
Results
We found that treatment was effective in women with stage 1 hypertension at baseline. Based on this finding, we also estimate that this intervention satisfies normative cost-effectiveness thresholds, even when lifetime treatment is needed to preserve the impact, so long as treatment is only continued in those who respond to treatment.
Conclusions
Direct delivery of healthy foods and checks that can only be spent on produce are a potentially cost-effective intervention for the management of hypertension among Native American women with stage 1 hypertension. Further research is needed to understand why we found an impact only for this group.

Finally, the generated random numbers are utilized to secure the DOCX text, novel Steganography algorithm to secure the text in an image and novel visible encrypted Watermarking.
Challenges in Achieving Consensus on Data Localization: Digital Inequality of Digital Service Trade
Authors: Gao Yuliang , Xie Zhiyong , Zhang Xiaohang 
Published: February 2024

Abstract

The disagreements on data localization policies significantly hamper the progression of digital service trade and free cross-border data flow. This study adopts the Theory of Comparative Advantage and the Heckscher-Ohlin Theory (H-O Theory) to construct an analytical model that investigates the inequality of digital service trade on the well-being of nations and the valuation of digital factors. Our findings suggest that digital service trade exacerbates the terms of trade for developing countries. In an environment of unrestricted data flow, developed countries capitalize on the data resources from developing nations, thereby augmenting their digital comparative advantages and factor endowments. The dynamics foster a state of digital inequality or digital poverty, where late-developing countries are disadvantaged in keeping pace with their developed counterparts. Notably, data localization, while seemingly a protective measure for developing countries, may not be the optimal strategy. It potentially undermines the overall well-being of all participants by diminishing network effects. The paper argues that the path towards the liberalization of digital trade and data flows will be a lengthy and complex one, demanding concerted international efforts to overcome entrenched trade barriers

A Reflective Academic Research Writing Among Graduate Students of Batangas State University, Philippines
Authors: Aceron Romel M. , Sapungan Ronel M. 
Published: February 2024

Abstract
This paper empirically examines the thesis and dissertation writing process, advising, and critiquing practices at Batangas State University's graduate schools. Historically, the study reveals that the number of graduates accounts for slightly more than three percent of the total enrollees each terminal or academic year. The research contrasts the present findings with existing research development manuals from 2008 and 2017, both within BatStateU and other universities, identifying a lack of resemblance in content. In previous manuals, demographic profiles of graduate students were limited to basic factors such as age, gender, degree program, specialization, status, year started, and year graduated. Positive research writing experiences were reported, with minimal encountered problems. Significant relationships were identified only between gender and research writing, while no significance was found in age, degree program, specialization, status, year started, and year graduated. The study proposes inputs for designing and developing a research writing Manual (ARWM) for graduate schools, emphasizing the need for a broader perspective by considering inputs from past batches and academic years. A call for a triangulation approach is suggested to refine and implement the proposed ARWM effectively.

Authors: Morales-García Mardel , Sairitupa-Sanchez Liset Z. , Morales-García Sandra B. , Cabanillas-Chavez María Teresa , Rivera-Lozada Oriana , Morales-García Wilter C. 
Published: February 2024

Abstract

Background
Positive thinking skills are fundamentally important in various fields, including mental health, education, and medicine. Within the context of medical education, where stress and pressure are prevalent, positive thinking can be a transformative force in enhancing resilience and empathy. However, careful validation of measurement tools is required to ensure their applicability in different cultural contexts.
Objective
The aim of this study was to adapt and validate the Positive Thinking Skills Scale (PTSS) among Peruvian medical students.
Methods
An instrumental study was conducted. A total of 408 Peruvian medical students aged between 18 to 35 years (M = 19, SD = 2.55) participated. The Positive Thinking Skills Scale (PTSS), academic self-efficacy, and burnout were used. A confirmatory factor analysis (CFA) was performed to assess the factorial structure of the PTSS. Additionally, a sequence of hierarchical variance models was used to evaluate measurement invariance by gender. For the reliability assessment, Cronbach's alpha (α) and omega (ω) coefficients were used.
Results
The CFA supported the unifactorial structure of 8 items with adequate goodness-of-fit indices: χ2 (20) = 69.860, CFI = 0.95, TLI = 0.93, RMSEA = 0.08 (90% CI: 0.06–0.09), SRMR = 0.04. Reliability using Cronbach's Alpha (α = 91) and McDonald's Omega (ω = 91) was excellent. Likewise, convergent and discriminant validity between the PTSS and measures of academic self-efficacy and burnout was demonstrated.
Conclusions
The Peruvian version of the PTSS is effective in measuring positive thinking skills. The PTSS represents a valid, reliable, and invariant tool for assessing and promoting positive thinking, which has profound implications on the mental health and overall well-being of future doctors.
The prognostic impact of surgical staging procedures in patients with colorectal and appendiceal peritoneal metastases undergoing CRS-HIPEC
Authors: Ghanipour Lana , Wallin Johan , Cashin Peter , Graf Wilhelm 
Published: February 2024

Abstract

Background
Surgical staging procedures are used to select patients with peritoneal metastases for surgery. We aimed to evaluate the prognostic impact of surgical staging procedures and the proportion of abdominal wall metastases in patients with peritoneal metastases scheduled for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC).
Methods
Data were collected from a prospective maintained HIPEC register 2012 to December 2019. Patients with peritoneal metastases originating from colorectal or appendiceal adenocarcinomas were included. Information about surgical staging procedures was registered. Results were then compared with those registered at definite CRS-HIPEC surgery and survival was analysed in relation to surgical staging procedures.
Results
In total, 167 patients were included, of whom 45 had undergone a surgical staging procedure before CRS-HIPEC. Median overall survival in the surgical staging group was 1.89 years and in the non-staging group 3.19 years (p = 0.01). In the surgical staging group, eleven patients developed abdominal wall metastases (24%) compared with four (3%) in the non-staged group (p < 0.001). Fifteen staged patients (33%) were considered inoperable at definite surgery (open-close). PCI score (p < 0.001) was higher at definite surgery in patients who had undergone a staging procedure. Factors associated with shorter overall survival in univariate analysis were: a separate surgical staging procedure prior to CRS-HIPEC, PCI ≥ 21 and presence of signet ring cells. However, a staging procedure was not associated with a shorter overall survival in multivariate analysis.
Conclusion
Surgical staging procedures are associated with a risk of inoperability and development of abdominal wall metastases. The use of a separate surgical procedure for staging patients before CRS-HIPEC should be selective.

Authors: GHIDINI Filippo , ANDREETTA Marina , DE CORTI Federica , BENETTI Elisa , VIDAL Enrico , GAMBA Piergiorgio , LEON Francesco FASCETTI 
Published: February 2024

Abstract
Purpose
To investigate the impact of after-hours surgery on the outcomes of paediatric kidney transplantation (KT).
Methods
Medical records of paediatric KTs performed at a single institution between 2013 and 2021 were retrospectively reviewed. The population was split into three groups according to the incision time and calendar: ordinary day (8.00 AM – 6.30 PM), day-off, and night-time (6.30 PM – 8.00 AM). The following endpoints were compared: ischemia times, length of surgery, complications, delayed graft function (DGF), primary graft non function (PGNF) and eGFR at three-month follow-up.
Results
Ninety-six non-living donor KTs were performed, median age 11 (IQR 4.3-14) years and median body weight 26 (IQR 13-50) kg. Forty-one (43%) were performed during night-time and 28 (29%) during day-off. Ischemia times were similar (p=0.769, p=0.536). Day-off KTs presented an extended length of surgery (p=0.011). Thirty-two complications were reported in 31 KTs. No difference in the overall rate of complications, DGF, PNGF and three-month eGFR was found (p=0.669, p=0.383, p=0.949, p=0.093). Post-operative bleedings were more common in days-off (p=0.003).
Conclusion
The number of paediatric KTs performed during after-hours was considerable. Even though similar outcomes were reported, more caution should be focused on the KTs performed in days-off to avoid severe complications.
