Abstract With the reform of China’s power system, power transmission and transformation project (hereinafter referred to as PTATP) are gradually developing in the direction of integration, informatization, large-scale and systematization. Therefore, the traditional project cost can no longer meet the needs of the society, which requires the project cost based on BD (hereinafter referred to as BD) technology. Through the information platform (hereinafter referred to as IPF), we can collect a lot of information, including policies and regulations database, talent and machine price information database, project cost index database, industry information database, etc., which will provide important support for project cost. Project cost informatization will solve the problems of low information sharing rate, low information value and high information cost, which will more scientifically complete the cost of PTATP. Based on BD technology, we can collect, sort out and analyze the cost information data of PTATP, which will fully explore the data value. Firstly, this paper analyzes the main algorithms needed for project cost. Finally, this paper constructs a PTATP cost IPF based on BD analysis, which will provide accurate countermeasures.

Purpose: Repeated hospitalization could be a proxy of unnecessary or preventive admission in South Korea where barriers to hospitalization are relatively low. This study aimed to estimate the current status of repeated hospitalization due to ambulatory care sensitive conditions (ACSC) in South Korea.Methods: Using the National Health Information Database, repeated hospitalization databases were constructed in units of episodes for patients who had been admitted more than twice between January 2017 and December 2018. The number of hospitalizations, total in-hospital days, and total medical expenditure were calculated and compared by patient characteristics in both of the entire patient group and the ACSC patient group.Results: Of total hospitalization episodes, 26.6% reported repeated admission, and 6.7% of repeated hospitalization was due to ACSC. A total of 183,110 patients with ACSC had been admitted an average of 2.9 times and spent an average of KRW5,630,118. In other words, KRW1,309 billion had been spent for repeated hospitalization due to ACSC. The scale of medical expenditure was relatively large in the highest and lowest socioeconomic status.Conclusion: Repeated hospitalization for ACSC can be considered a simple and intuitive indicator when assessing unnecessary hospitalizations or evaluating healthcare policy.

The need for a shift in diet toward a more sustainable one has reached an urgency in certain regions, including Iran, due to more rapid climate change and a higher level of vulnerability. This study was undertaken to identify and summarize available data on changes required in the current Iranian diet to make it more sustainable and the extent to which current policies in the country have addressed such a shift. In this study, PubMed, Scopus, and Web of science, as well as Iranian scientific search engines, including Scientific Information Database and Magiran, were systematically searched from January 1990 to July 2021. A total of 11 studies and policy analyses were included in this study. Based on the findings, moving Iranian diet toward sustainability will require increase in consumption of dairy, fruits, vegetables, cereals, poultry, and legumes and decrease in consumption of bread, rice, pasta, red meat, eggs, fats, sugars, and sweets. There has been a great deal of effort and investment on policies and strategies to decrease the amount of sugar, salt, and fat (specifically trans-fatty acids) in the Iranian diet, which makes it more sustainable healthwise. Several policies and programs have been implemented to tackle non-communicable diseases (NCDs) by reducing access to unhealthy foods, which is in line with health dimension of a sustainable diet. However, there is almost no direct address to ecological aspect of sustainable diet in the food and nutrition policy documents in the ccountry. Development of an enabling environment to a sustainable diet will require policy and actions to improve public awareness, support study to provide evidence and identify possible alternatives, and plan and implement interventions/programs to promote and facilitate healthy and sustainable diets.

Introduction: Antimicrobial peptides (AMPs) are small molecules which are known to exert destructive effects upon pathogenic microorganisms. AMPs are designed from proteins obtained from various sources and tested under in vitro conditions to deduce their antimicrobial activity. Materials and Methods: A few of the peptidoglycan hydrolases such as lysostaphin (AAB53783.1), enterolysin (AGG79281.1), and endolysin (YP_009901016.1) were selected for the study based on an extensive text mining process. The protein sequences of the proteins were retrieved from the NCBI (National Centre for Biotechnology Information) database in the FASTA format (https://www.ncbi.nlm.nih.gov/protein/). Results and Discussion :In the antimicrobial protein lysostaphin, three antimicrobial peptide are been found, in which two is active and other is inactive, and one has antifungal property with a score of -0.15, and one having cell penetrating property, in which all are non toxic. Conclusion: The present study predicts AMPs from lysostaphin, entero and endolysins. These peptides were found to possess antifungal, anti-biofilm properties. Most of the peptides predicted were found to be non-cell penetrating and non-toxic.

Background: The COVID-19 pandemic has led to a rapid shift in student education style from face-to-face to electronic learning. Since the education satisfaction index is considered as a measure of the quality of educational services, therefore, this study aimed to assess E-Learning Satisfaction (ELS) in medical and non-medical students during COVID-19 pandemic. Methods: Articles that had been published from 22 Dec 2019 to 4 Jan 2021 were identified through searching databases including PubMed, Scopus, Elsevier, Google Scholar, Web of Science and Iranian Scientific Information Database (SID), Health.barakatkns, IranDoc, Civilica and MagIran using the following keywords: “Distance learning”, “Virtual learning”, “E-Learning”, “Satisfaction”, “COVID 19”. We systematically reviewed all studies that reported ELS. In this study, meta-analysis was used to estimate the pooled ELS. Results: Overall, 184 records were identified by the electronic search, of which 24 relevant studies were included in meta-analysis. The pooled ELS in medical, non-medical and overall were 58.1% (50.5%-65.7%), 70.1% (66.8%-73.5%) and 63.8% (58.9%-68.8%) respectively. Conclusion: According to our results and lower ELS in medical students in comparison with non-medical students, designing new E-Learning methods for medical students has been suggested.

AbstractAtopic dermatitis (AD) is associated with allergic comorbidities, such as asthma, allergic rhinitis (AR), and allergic contact dermatitis (ACD). The etiology of keloid is largely unknown; however, AD and keloid share inflammatory pathways characterized by T-helper cell 2 cytokines and increased dermal fibroblast activity. The prevalence of keloids has been reported to increase in patients with AD, but it remains controversial. This study aimed to estimate the prevalence of keloids in patients with AD, and compare it with the prevalence of other comorbidities of AD. We assessed the Korean National Health Information Database and medical records including coexisting asthma, AR, and ACD. Single and multiple logistic regression models were created for keloids and each allergic disease. The prevalence of keloids was higher in the AD group than in the control group. Among patients with AD, adolescents and adults had a higher prevalence of keloids than infants and children. The risk of keloids was high with AD alone, and coexisting asthma significantly increased the risk. Similarly, the risk of keloids was higher in AR associated with AD and ACD associated with AD than in AD alone. Thus, among Koreans, patients with AD have a higher risk of keloid development, with coexisting allergic diseases increasing the risk.

Abstract At present, China has gradually entered the era of computer network, which is widely used in daily life and production. The previous information operation mode and information database can no longer meet the needs of the current stage of work. Its birth not only improves the defects in the previous computing network technology, At the same time, with its efficient information collection, analysis and processing functions, people’s living standards and work efficiency have been significantly improved. Based on the concept, characteristics and application advantages of artificial intelligence technology, this paper further analyzes the key points of application, hoping to provide powerful help for relevant enterprises or units at the present stage.

The study of the partnership organization mechanism (POM) aims to answer the question of how an organization manages the mechanical operation of the partnership and how the partnership system shapes itself in order to achieve a fairer balance across all junctions of the POM, through shafts connected into a single mechanism. The study has led to a deeper understanding of the empirical operation of the POM and has led to the identification of 20 POM configuration principles, the harmonization of which, in accordance with the principle of coherence, enables sustainability to be achieved and managed. The study is exploratory and therefore empirical facts supporting theoretical insights were sought. The information database of the study consists of 5-year observation data of Lithuanian local action groups, exploratory survey data and in-depth interviews for verification of the phenomenon. The empirical study allowed us to verify the theoretical operation of the POM and helped us to determine the content and purpose of the relationships between different groups of stakeholders in the region. A total of 10 POM empirical models have been detected, which confirmed the fundamental thesis of the study that sustainability can be managed by ensuring the harmonious operation of the system and by controlling the level of system coherence.
