Authors: Wang Liangyan , Ying Zhen , Zhao Qi , Yan Chunfeng , Zhang Fujie
Published: September 2022

Taking the 13 years pure artificial forest Phoebe chekiangensis and heterogeneous mixed forests in Tiantong mountain, Zhejiang Province as the research object, the characteristics of stand development, tree competition differentiation, tree height/breast diameter ratio and dominant wood growth were compared and analyzed from the perspective of ecology. The results show that compared with pure forests, the growth advantages of heterogeneous mixed-age forests were significant. Average breast diameter growth of stand increased 1.8%; the growth of single plant wood accumulation increased 7.4%. The relationship between tree height and diameter showed that the high growth of Phoebe chekiangensis individuals in the heterogeneous mixed forest was significantly promoted, and the high growth of the tree was 8.4% higher than that of pure forest. 1–5 grade wood scale sizes Phoebe chekiangensis in heterogeneous mixed forests and pure forests are ranked grade 3 (43.7%) > grade 2 (26.5%) > grade 4 (15.7%) > grade 1 (12.9%) > grade 5 (1.2%); grade 3 (34.7%) > level 2 (25.6%) > level 4 (20.0%) > level 1 (18.2%) > level 5 (1.2%); the straight-diameter structure shows a normal distribution, and the degree of differentiation of pure forests is greater than that of heterogeneous forests. The dominant trees of Phoebe chekiangensis pure forest and heterogeneous forest accounted for 18.2% and 12.9% of the total number of plants respectively, providing a reserve of 51.1% and 35.4% respectively, reflecting the contribution of dominant trees caused by the self-thinning effect.

Published: September 2022

This work was carried out with the purpose of generating ecological and silvicultural information oriented to sustainable management. The horizontal structure was evaluated using the importance value index of Curtis and Macintosh, the vertical structure using Finol’s methodology. Through the sociological position index, the percentage natural regeneration and the extended importance value index were estimated in order to infer the permanence of the forest ecosystem. The floristic composition was represented by species of the families Anacardiaceae, Apocynaceae, Fabaceae, Santalaceae, Rhamnaceae, Sapotaceae, Simarubaceae, Ulmaceae, Zygophyllaceae, Capparidaceae, Borraginaceae and Achatocarpaceae. In the horizontal structure, the species with the highest rank was Acacia praecox, followed in order of importance by Schinopsis balansae, Aspidosperma quebracho blanco and Prosopis kuntzei. According to sociological position, Acacia praecox was the most representative species, followed by Patagonula americana, Schinus longifolius, Proposis kuntzei and Aspidosperma quebracho blanco. The species with the best regeneration values were Achatocarpus nigricans and Acacia praecox in the shrub layer and Patagonula americana in the tree layer. The extended importance index consolidated the category of Acacia praecox in the community and gave a better category to Schinopsis balansae, Aspidosperma quebracho blanco, Prosopis kuntzei and Patagonula americana.

Authors: Wu Guoyong , Dong Rui , Yu Fawen
Published: September 2022

Small watershed ecological compensation is an important economic means to solve the contradiction between protecting the ecological environment and developing the economy. Taking the Changtian small watershed in the Xixiu District of Anshun City as an example, this paper uses the ecological service function value method to roughly calculate the ecological service function value of the small watershed ecosystem: the ecological service function value of the Changtian small watershed is 913.586 million yuan, and the total amount of ecological compensation is 11.6245 million yuan, of which the farmland system compensation is 1.3194 million yuan, the forest system compensation is 7.5336 million yuan, and the water system compensation is 256,000 yuan, The compensation for the fruit forest system is 2,515,500 yuan. Based on the value of ecosystem service function, the compensated and non-compensated ecosystem service functions are distinguished, and the equivalent factors that different ecosystems can provide compensated ecosystem functions are expressed, so that the determination of ecological compensation amount is scientific and more accurate, and then provides a basis for the determination of ecological compensation standard of the small watershed.

Published: September 2022

Urban trees are one of the valuable storage in metropolitan areas. Nowadays, a particular attention is paid to the trees and spends million dollars per year to their maintenance. Trees are often subjected to abiotic factors, such as fungi, bacteria, and insects, which lead to decline mechanical strength and wood properties. The objective of this study was to determine the potential degradation of Elm tree wood by Phellinus pomaceus fungi, and Biscogniauxia mediteranae endophyte. Biological decay tests were done according to EN 113 standard and impact bending test in accordance with ASTM-D256-04 standard. The results indicated that with longer incubation time, weight loss increased for both sapwood and heartwood. Fungal deterioration leads to changes in the impact bending. In order to manage street trees, knowing tree characteristics is very important and should be regularly monitored and evaluated in order to identify defects in the trees.

Published: September 2022

Forest fire, as a discontinuous ecological factor of forest, causes the changes of carbon storage and carbon distribution in forest ecosystem, and affects the process of forest succession and national carbon capacity. Taking the burned land with different forest fire interference intensity as the research object, using the comparison method of adjacent sample plots, and taking the combination of field investigation sampling and indoor test analysis as the main means, this paper studies the influence of different forest fire interference intensity on the carbon pool of forest ecosystem and the change and spatial distribution pattern of ecosystem carbon density, and discusses the influence mechanism of forest fire interference on ecosystem carbon density and distribution pattern. The results showed that forest fire disturbance reduced the carbon density of vegetation (P < 0.05). The carbon density of vegetation in the light, moderate and high forest fire disturbance sample plots were 67.88, 35.68 and 15.50 t∙hm-2, which decreased by 15.86%, 55.78% and 80.79% respectively compared with the control group. In the light, moderate and high forest fire disturbance sample plots, the carbon density of litter was 1.43, 0.94 and 0.81 t∙hm-2, which decreased by 28.14%, 52.76% and 59.30% respectively compared with the control group. The soil organic carbon density of the sample plots with different forest fire disturbance intensity is lower than that of the control group, and the reduction degree gradually decreases with the increase of soil profile depth. The soil organic carbon density of the sample plots with light, moderate and high forest fire disturbance is 103.30, 84.33 and 70.04 t∙hm-2 respectively, which is 11.670%, 27.899% and 40.11% lower than that of the control group respectively; the carbon density of forest ecosystem was 172.61, 120.95 and 86.35 t∙hm-2 after light, moderate and high forest fire disturbance, which decreased by 13.53%, 39.41% and 56.74% respectively compared with the control group; forest fire disturbance reduced the carbon density of eucalyptus forest, which showed a law of carbon density decreasing with the increase of forest fire disturbance intensity. Compared with the control group, the effect of light forest fire disturbance intensity on the carbon density of eucalyptus forest was not significant (P > 0.05), while the effect of moderate and high forest fire disturbance intensity on the carbon density of eucalyptus forest was significant (P < 0.05).

Published: September 2022

Urban green areas provide various services to society and the environment. The Bosque San Juan de Aragón is one of the few green areas in the northeast of Mexico City and the current condition of its trees in terms of health is not known with precision. In the present study, the protocol for the crown condition indicator was implemented and adapted in 28 circular plots of 0.1 ha, randomly established in the aforementioned forest. All trees within each plot were measured for normal diameter (ND) and total height (TA), and their taxonomic classification, crown condition and plantation density were determined. For crown condition, six variables were measured: proportion of live crown (PLC), crown density (CD), crown transparency (CTR), dieback (DB), crown position (CP) and light exposure (LE). The first four were measured in 5% classes and the remaining two were measured on an ordinal scale. A total of 760 trees were evaluated, grouped into 10 families, 11 genera and 12 species. The average values for the crown variables were 56.37% PLC, 44.38% CD, 4.04% DB and 38.4% CTR. Only PLC reached the established standards of tree health found in other studies, while CD was low and CTR and DB values were high.
Analysis of the synergistic mechanism of forest eco-economic system
Authors: Wang Guangju , Ruan Hongyi , Yang Jianzhou
Published: September 2022

Based on the collective forest with common use rights, the social-ecological system analysis framework and autonomous governance theory proposed by Elinor Ostrom are introduced in the forest eco-economic system to analyze the interaction logic among the first-level subsystems and the secondary variables of the forest eco-economic system and the variables related to the autonomous governance of the system to explore the synergistic mechanisms affecting the forest eco-economic system. The results show that: in the case of information asymmetry, collective actions of governmental and non-governmental organizations will aggravate the dilemma of forest eco-economic synergistic development; actors extract forest resource units from the forest resource system to achieve economic benefits; and renewable resources of forest ecosystems can be sustained in the long term when the average extraction rate of humans from forest ecosystems does not exceed the average replenishment rate.
Pragmatism and Creativity: Patenting the School Art Manifesto from Dewey’s Aesthetic Experience
Authors: Ortiz Carlos Manuel Montenegro
Published: September 2022

An original way to make sense of the aesthetic experience concept – in a Deweyan perspective – is from the Art-Education binomial. After studying the pragmatist philosophical category of Experience in John Dewey, a product of Doctoral theoretical research in education, it was possible to characterize a new art movement: School Art. Hence, this conceptual-theoretical finding will expand a wide range of art movements that emerged between the nineteenth century and contemporaneity: Art Nouveau, Impressionism, Abstract Art, Futurism, Action Painting, and Children’s Art, among many others. However, because of lexical reasons and hoping to achieve greater acceptance among theorists, the so-called School Art will patent from this paper as a neologism named from now on as Artscholarism. Thus, its philosophical-historical foundations, characteristics, and description will be the article’s primary purpose. In that sense, psychological and historical discussions will emerge throughout the paper. In conclusion, the new art movement – Artscholarism – comes from Deweyan thinking and is framed by creativity and a social context.

This study entitled Mapping Grammatical Relations of English Verbs, concerns on numbers of arguments that a verb could assign and how an argument is syntactically motivated in clauses of which the mood is declarative. This study involves to library research, and the method that was applied in this study was descriptive method which describes linguistics phenomena like what it actually is. The data of this study were taken from the Corpus of Contemporary American English (COCA) by inputting verbs those have been determined to the website http://www.english-corpora.org/coca/. The main theory applied in this study was Kroeger’s (2005) regarding to transitivity and grammatical relation. Based on the analysis, verbs in English require argument(s), terms or obliques. An intransitive verb assigns a term that stands as subject, a transitive verb assigns two terms those stand as subject and primary object. On the other hand, a ditransitive verb assigns three terms those stand as subject, primary object and secondary object. In addition, there is an argument that stands as oblique.
The Musical Motifs of Vladislav Khodasevich’s The Heavy Lyre
Authors:   Institute for Russian and Altaic Studies, CBNU, Lee Jonghyeon
Published: September 2022

This article analyzes the musical motifs of Vladislav Khodasevich’s fourth poetry book The Heavy Lyre (1922) and reveals what role those motifs play in the collection’s composition and signification. The music-related poems that bookend the collection are clues that hint at the relationship between earthly sounds and heavenly music. In the collection’s first poem, “Music,” a heavenly ‘symphony’ is suggested as something that can be felt indirectly in daily life in the form of humor. Likewise, in “Elegy,” closer to the middle of the collection, the sounds of life and the music of the soul are settled in a hierarchy, and the sounds of life are both the result of uncertain senses and a condition of existence from which the poet cannot escape. In the final poem of the collection, “Ballad,” sounds of life recede into the background for the arrival of music. So while “Music” addresses the relationship between daily life and music, the conflict between the two is deepened in the middle of the collection, and then “Ballad” presents daily life as a niche in which music can emerge. An analysis of such roles in The Heavy Lyre will serve as the basis for studying the structure of the poet’s monumental collected works, Collection of Poems (1927).

Authors: Walker Richard W. , Roman Gustavo C. , Zhang Yi Jonathan , Acres Omar
Published: September 2022

Background:

Ventriculoperitoneal shunt (VPS) insertion is one of the most common neurosurgical procedures done around the world to treat hydrocephalus. The occurrence of spontaneous migration of the peritoneal shunt catheter into the thoracic cavity is a very rare complication; we report here case number 27 of respiratory complications of a VPS in a patient with normal-pressure hydrocephalus (NPH).

Case Description:

A 76-year-old woman with Alzheimer’s disease and anosognosia was diagnosed idiopathic NPH treated surgically with a VPS. Pleural effusion and pulmonary complications occurred 4 weeks after the insertion of the shunt due to the spontaneous migration of the peritoneal catheter of the VPS into the thoracic cavity. The hydrothorax of cerebrospinal fluid was drained and the distal catheter was removed and replaced. The patient made an uneventful recovery.

Conclusion:

Due to the rarity of this complication, there are no standard corrective procedures. Some of the methods used to diagnose and successfully treat this rare complication of the VPS are presented.

Authors: Edwards Caleb Simpeh , Ammanuel Simon Gashaw , Silva Ogonna N. Nnamani , Greeneway Garret P. , Bunch Katherine M. , Meisner Lars W. , Page Paul S. , Ahmed Azam S.
Published: September 2022

Background:

Health literacy profoundly impacts patient outcomes as patients with decreased health literacy are less likely to understand their illness and adhere to treatment regimens. Patient education materials supplement in-person patient education, especially in cerebrovascular diseases that may require a multidisciplinary care team. This study aims to assess the readability of online patient education materials related to cerebrovascular diseases and to contrast the readability of those materials produced by academic institutions with those of non-academic sources.

Methods:

The readability of online patient education materials was analyzed using Flesch-Kincaid Grade Level (FKGL) and Flesch Reading Ease (FRE) assessments. Readability of academic-based online patient education materials was compared to nonacademic online patient education materials. Online patient education materials from 20 academic institutions and five sources from the web were included in the analysis.

Results:

Overall median FKGL for neurovascular-related patient online education documents was 11.9 (95% CI: 10.8–13.1), reflecting that they are written at a 12th grade level, while the median FRE was 40.6 (95% CI: 34.1–47.1), indicating a rating as “difficult” to read. When comparing academic-based online patient education materials to other internet sources, there was no significant difference in FRE and FKGL scores (P = 0.63 and P = 0.26 for FKGL and FRE, respectively).

Conclusion:

This study demonstrates that online patient education materials pertaining to cerebrovascular diseases from major academic centers and other nonacademic internet sites are difficult to understand and written at levels significantly higher than that recommended by national agencies. Both academic and nonacademic sources reflect this finding equally. Further study and implementation are warranted to investigate how improvements can be made.
Deep brain stimulation for refractory obsessive-compulsive disorder: A review and analysis of the FDA MAUDE database
Authors: Porwal Mokshal H. , Karra Hamsitha , Sharma Umesh , Bhatti Danish
Published: September 2022

Background:

Deep brain stimulation (DBS) is used as a treatment option for patients diagnosed with a form of obsessive-compulsive disorder (OCD) that is highly resistant to conventional treatment methods. In 2009, DBS was granted a humanitarian device exemption-approval by the Food and Drug Administration after promising preliminary data. Monitoring of long-term safety data through post market surveillance of adverse events has not yet been conducted for DBS in OCD patients. This study aims to address this critical knowledge gap.

Methods:

All patient- and device-related (PR; DR) reports from January 1, 2012, to December 31, 2021, were downloaded and compiled from the manufacturer and user facility device experience (MAUDE) database pertaining to DBS for OCD using the product class name “Deep Brain Stimulator For OCD.” Data in this study were examined using descriptive statistics to evaluate for frequency of reporting.

Results:

The most frequently reported PR adverse event categories included psychiatric (40%), neurological (19%), other (14%), decreased therapeutic response (10%), and infections (10%). The most frequent DR reports were high impedance (14%), energy output problem (7%), battery problem (7%), malposition of device (7%), and improper/incorrect procedure or method (7%).

Conclusion:

The PR and DR adverse events in our study align with the previous findings of adverse events. They also further solidify that DBS for refractory OCD may be a viable option for the right patient population. However, further studies are essential given the limitations of the MAUDE database.
Treatment of Osteomyelitis of the Toes Without Amputation in the Wound Clinic Setting
Authors: Treadwell Terry
Published: September 2022

Ulcers of the distal toe are common in patients with toe deformities and many times are complicated by osteomyelitis of the phalanx. Amputation of the toe is the standard treatment in many institutions; however, this can lead to abnormal biomechanics of the foot predisposing the patient to recurrent ulceration and further amputations, especially in patients with diabetes and those with neuropathy. It has been found that conservative, local operative procedures to remove the infected bone can avoid these complications and even avoid long-term antibiotic therapy. Many of these procedures can be performed in the wound clinic. To show its utility, a case report of this procedure and a small series of these patients treated in the wound clinic are presented.
Dracaena cinnabari Methanolic Extract impairing Migration and inhibiting Growth of Nasopharyngeal Carcinoma Cells through Induction of Intrinsic Apoptotic Pathway In Vitro
Authors: Ali-Saeed Rola , Shaghayegh Gohar , Alabsi Aied M.
Published: September 2022

The resin of Dracaena cinnabari Balf. f. has demonstrated antiviral, antibacterial, antioxidative, analgesic and anti-inflammatory properties, which presents some proof for its effectiveness in traditional use. Despite the broad health benefits of Dracaena cinnabari, few research has been conducted on its anti-tumour effect. We have previously shown that Dracaena cinnabari Balf. f methanolic extract (DCBME) induces apoptotic cell death in human tongue squamous cell carcinoma cell line and significantly reduces its migration capacity. The anti-tumour potential and mechanism of action of DCBME in Nasopharyngeal Carcinoma (NPC) have not yet been elucidated. In our recent paper, we showed the disruption of mitochondrial membrane potential and the induction of the intrinsic apoptotic pathway through caspase 3/7 activation. In the present study, we aim to investigate the effect of DCBME on proliferation, morphological changes, cell death, cell cycle arrest and cell migration of NPC cells. NPC cells (C666-1 and HK-1) were treated with DCBME and the mechanism underlying its anti-tumour effect was explored by examining cell proliferation, induction of apoptosis and cell migration using MTT assay, phase-contrast and fluorescence microscopy, propidium iodide staining, DNA fragmentation and wound healing assays. DCBME significantly inhibited NPC cell proliferation in a time and dose-dependent manner. It induced marked apoptotic morphological changes, apoptotic DNA laddering and S and/or G2/M-phase cell cycle arrest. DCBME also inhibited the migration of NPC cells. Together with our previously reported anti-tumour effect of DCBME, the findings suggest that DCBME deserves further investigation as a promising anti-tumour agent for human Nasopharyngeal Carcinoma cells therapy.

It is the second leading cause of mortality in Acquired Immuno deficiency Syndrome (AIDS) patients worldwide. The cryptococcal infection occurs in subacute meningitis, patients having CD4+ T Lymphocytes count below 100 cells/micro liter. However, in severe immunosuppressed patients, Cryptococcus neoformans can infect any human organ including the bone marrow. This case presents the disseminated cryptococcosis with bone marrow involvement and asymptomatic meningitis, focusing on the role of bone marrow aspirate and biopsy study in HIV infected patients. A 42 year old HIV infected male patient with a CD4+ T Lymphocyte count of 25 cells/μl was admitted to the emergency department of Dr. Ram Manohar Lohia Institute of Medical Sciences, Lucknow, India. The patient underwent a CSF examination to rule out the infection of meningitis patient had no signs of meningeal irritation and neurological examinations were normal. The CSF culture showed Cryptococcus sp. The patient was given Amphotericine B plus Fluconazole therapy according to IDSA guidelines. However, the patient developed acute kidney injury stage 3 and was given fluconazole monotherapy. The symptoms disappeared and CSF culture for fungi was negative after 2 weeks of treatment. Bone marrow infection caused by Cryptococcus neoformans is a rare presentation of cryptococccosis.

Considerations of accounting standards that can be used to disclose Cryptographic assets in financial reports
Authors: عبدالعزيز Majida AbdulMajeed
Published: September 2022

Cryptographic assets are a digital form of currency that uses mathematical equations and block chain technology to encrypt data. The popularity of this type of currency has grown exponentially over the past few years due to more people and companies using it despite the refusal of central banks and country authorities to recognize cryptocurrencies as money. However, some companies have begun to accept it as payment for goods and services. It is expected that more people will turn to cryptocurrencies in the future. With this, companies will have to find ways to account for and report them in the financial statements, however, the Financial Accounting Standards Board (FASB) has not yet determined how to account for cryptocurrency, leaving companies without formal guidance on the subject. The purpose of this paper is to present potential accounting policies to display how companies will report cryptocurrencies in the future based on evidence derived from a review of the accounting literature. The need to address digital currency problems was recommended by the International Accounting Standards Board.

Authors: Rzepczyk Szymon , Majer Jakub , Obst Maciej
Published: September 2022

Road safety barriers are a basic element of the road infrastructure aimed at improving the safety of road users. Design parameters and indications for assembly are strictly regulated by the GDDKiA (General Directorate for National Roads and Motorways) guidelines in accordance with the European standards. In Poland, the most commonly used barriers are thin-walled metal sheet barriers, rope barriers, and concrete ones. The types differ in terms of technical parameters and level of security they provide. One of the purposes of installing road safety barriers is to protect road users from hitting an obstacle in the vicinity of the road, and to protect people around the accident from the effects of an uncontrolled vehicle leaving the road. The effects of a collision caused by hitting a protective road barrier depend mainly on the type of the barrier and the vehicle. The authors made a detailed and interdisciplinary analysis of data on accidents resulting from hitting a road safety barrier, comparing them with information available in the literature, combining the technical aspects of the use of barriers with a medical description of the description of typical injuries.
