Background: Dental sealants have been used to reduce the incidence and severity of dental caries in the pits and fissures of teeth for over 40 years. Since that time, numerous scientific discoveries have led to the development of multiple generations of new sealant materials. Aim: The aim of this paper is to summarize the findings of reviews regarding the types of pit and fissure sealants, indications and contraindications for their use. Methods and materials: Previous systematic reviews on this topic were used as the basis for the current review. Cochrane, MEDLINE, Embase, and a few other bibliographic databases were searched for English and Bulgarian-language articles. The year of publication of the searched articles was limited from 2000 to 2020. Only articles in English and Bulgarian languages were read in full. Results: A total of 114 articles were identified by the literature search, the title and abstract of the articles were examined. Twenty-four original research studies met the inclusion criteria. They were read in full, and evidence was extracted for types of pit and fissure sealants, as well as indications and contraindications for their use. Conclusion: Evidence derived from the literature led to the conclusion that sealants are effective in preventing pit and fissure occlusal carious. The selection of the material used for silanization is made depending on a few factors that should be considered, such as patient's and tooth age, child's behavior and ability to isolate the surfaces which are going to be sealed. Regular examinations are required to be able to determine the need for reapplication of sealants and to maximize the effectiveness and results of the treatment.

Authors: Elendu Chukwuemeka J. , Wokekoro Ebiwari , Akujuru Victor A.
Published: January 2022

Contamination is the release of hazardous materials into the environment; which could be in the form of: waste, petroleum hydrocarbons and other unwanted materials. The release of these hazardous materials could affect soil nutrients and aggravate biodiversity loss. When the soil nutrient is impacted, it negatively affects its crop yield and production capabilities. Once there is contamination of the environment, remediation becomes necessary. This paper examines the effects of remediation of crude oil contaminated land on agricultural resources in Umuechem in Etche Local Government Area of Rivers State, Nigeria. Purposive sampling technique and a survey research design was adopted with the use of structured questionnaires administered on a sample size of sixty two (62) persons whose farmlands and other agricultural resources were contaminated and thereafter remediated. The sample size was made up of fifty four (54) literate and eight (8) illiterate persons. The questionnaire was interpreted in native language to the illiterate persons by either their children or any other relative. The data obtained from the survey were analysed using descriptive statistics such as tables and statistical package for social sciences (SPSS).The findings obtained indicated that there was a post-remediation low-crop-yield and recommended that remediation consultants should adopt techniques capable of completely removing contaminants from the environment.
「漢語形容動詞連用形 ni＋動詞述語節」與「漢語名詞 de+動詞述語節」之比較研究—以「本気(ni)」「本気(de)」之用法為例—
Authors: 陳志文 陳志文
Published: January 2022

現代日語中，有些同時兼具形容動詞和名詞的漢語，除了可以使用「漢語形容動詞 ni(副詞形)+動詞述語節」外，也可以使用「漢語名詞 de+動詞述語節」之形式。到底甚麼樣的情況，應該用甚麼樣的形態來修飾動詞述語節呢?這確實是一項耐人尋味的問題。本稿中，以此課題為基本，使用「BCCWJ(中納言)」這項資料庫為分析資料，以「本気(ni)」「本気(de)」之用法為例，考察分析「漢語形容動詞（ni）＋動詞述語節」構造及「漢語名詞（de）＋動詞述語節」之構造，闡明兩者使用上之差異。

 

In contemporary Japanese, some Chinese (or Kango) includes both adjectival verbs and nouns. There are two forms that can be used to modify the predicative verb clauses, “adjectival verb ni (adverbial form) + predicative verb clause” and “noun de(case marker) + predicative verb clause.” The study aims to discuss this area with an intriguing question: Based on different situations, which form should we use to modify the predicative verb clauses? With the analysis of the Balanced Corpus of Contemporary Written Japanese (BCCWJ-Chunagon) and the examples shown in this study, differences between the two forms can be fully investigated and explained.

Authors: Paul Kodji , Daniel Tchobsala , Adamou Ibrahima Adamou
Published: January 2022

Plant dynamics is a natural process that occurs in the ecosystem. This dynamic becomes abnormal in the presence of human pressure. The vegetation of the district of Mokolo (Cameroon) faces many anthropic factors that disturb its steady evolution. This work aims to evaluate the different factors that influence the vegetation dynamics in the south of the Mokolo District. All traces of anthropization were identified on all woody species in a rectangular plot (20 m x 100 m). All individuals with a height ≤1.30 m and a Dhp less than 10 cm were considered regenerating individuals. Among the main plant factors, dynamics identified, regeneration, spread type, phytogeographic type have positive impacts while logging, debarking, pruning, grubbing, trampling and burning have negative impacts. Regeneration is the main positive natural factor with the highest frequency in wooded savannas (321±95%). Timber harvesting is the main negative anthropogenic factor with a higher frequency in the home garden (85.00%) and the shrub savannas (68.66%). To reduce the negative impacts and increase the positive impacts, the government must implement reforestation projects in this ecologically fragile area.

Spider monkey optimization (SMO) algorithm is a new swarm intelligence optimization algorithm proposed in recent years. It simulates the foraging behavior of spider monkeys which have fission-fusion social structure (FFSS). In this paper, a modified spider monkey optimization algorithm is proposed. The self-adaptive inertia weight is introduced in the local leader phase to enhance the self-learning ability of the spider monkey. According to the function value of an individual, the distance from the optimal value is determined, so the inertia weight related the individual function value is added to strength the global search ability or local search ability. The proposed algorithm is tested on 20 benchmark problems and compared with the original SMO and the hybrid algorithm SMOGA and GASMO. The numerical results show that the proposed algorithm has a certain degree of improvement in convergence accuracy and convergence speed. The performance of the proposed algorithm is also inspected by two classical engineering design problems.

The transition from traditional teaching practices to remote education was sped up by the outbreak of COVID-19 pandemic dramatically. The international students who have to stay in their home countries due the travel restrictions rely on the online study. In this manuscript, we examine how the teaching methodology affects the outcome of remote education (e.g., an undergraduate program provided by CUMT, and a graduate program provided by Gachon University). Both SPOC and online streaming classes were evaluated based on the performance of international undergrads majored in chemical engineering. And multiscale simulations were adopted to elucidate the complex transport phenomena in chemical engineering classes to develop a more efficient method for distant engineering education. The preliminary results of this comparative study on online teaching practices indicate that active studies play an important role in online study for international students.
The effect of borders on identity building in minority life
Authors: Molnár Bodrogi Enikő
Published: January 2022

In my research, I have used the postmodern concept of border to analyze the influence of borders on identity building of a national minority, namely that of the Hungarians in Transylvania in the interwar period. According to recent border studies, borders can be dealt with as zones and as cultural and mental landscapes, which serve to make contacts between different entities (in the case of this research between different linguistic and ethnic groups).
The aim of this study is to seek possible answers to questions such as why and how people produce borders through symbols and narratives. How does the human perception of a landscape influence the shaping of a landscape and the way people treat that landscape? In a narrower sense, it analyzes topics like the interpretation of national minority existence, the bidirectional attempt to construct and deconstruct virtual borders and the symbolic value of the mother tongue for a minority. The basic materials of my present study are Transylvanian Hungarian literary texts.
As far as the theoretical basis of the study is concerned, I analyze the topic from the perspective of border studies, cultural and mental landscape studies and identity studies.
The comparative analysis of Lithuanian manorial-serf economy and hacienda economic system of Latin America in the context of capitalist world system: from the second half of the 18th to the second half of the 19th centuries
Authors: Žiemelis Darius
Published: January 2022

The paper compares for the first time in historiography the Lithuanian manorial-serf economy and Latin American hacienda economic systems of the second half of the 18th century to the second half of the 19th century in the context of the capitalist world system (CWS). The main focus will be on the explication in macro level of similarities and differences of structures and development trends of these systems. The analyzed period corresponds to the stage of both the dominance and intensification of manorial-serf economy in Lithuania and predominance and intensification of hacienda economy in Latin American countries and it was determined by the same factor of the industrial revolution. The study confirms the thesis that these economic systems belonged to typologically closed economic kind (they were focused on the serfdom method of production) in the global division of labor. It shows that both Lithuanian manorial-serf economy and haciendas of Latin America were not typical feudal enterprises, but displayed only peripheral (agrarian) capitalism features.

Many a times the use of rapid diagnostic tests for blood borne parasites like trypanosomiasis and Babesiosis is increasingly being used, but the gold standard for its detection is still the use of microscopy both as reference and confirmatory diagnosis. To determine the effectiveness of the adjusted stock giemsa staining technique over the conventional methods. Venous Blood samples were collected from 10 dogs in EDTA and then used for the simultaneous preparation of two thin and thick smear slides, one stained according to Giemsa 1:20 dilution for 30 mins while the other was stained using the Stock Solution for 30seconds the diluted with buffered saline for 20seconds and rinsed. Fixation of the thin smear was done in a covered staining jar containing anhydrous methanol for 1 to 2 min, after which the slides were air-dried. From the result obtained from 10 dogs blood samples gotten from the veterinary clinic, the adjusted giemsa staining technique showed a positive differentiation when compared to the 1:20 dilution, a total of 7 blood samples tested positive for blood borne parasites, Trypanosoma evansi, Babesiosis cani and Heart worm. The highest percentage occurrence was T.evansi (40%), Babesiosis cani(20%) and Heart worm (10%).The adjusted Giemsa staining technique serves as a fast, easy and less complex alternative to the 1:20 dilution, where the solution has to be diluted from the stock solution and then stained, although the only disadvantage to this technique would be easy contamination of the stock solution, but the advantages here is that it saves time, quicker result output and better differentiation microscopically.

In order to explore the relationship between peripheral lncRNA expression and coping style in schizophrenia patients, this study screened the peripheral blood mononuclear cells in 5 patients and 5 controls, and 10 differentially expressed lncRNAs were selected and validated in 96 patients and 50 controls by qPCR. Compared to control group, three lncRNAs (NONHSAT089447, NONHSAT021545, NONHSAT041499) were up-regulated in schizophrenia group. Among them, NONHSAT089447, NONHSAT021545 were negatively associated with positive coping style, and other four lncRNAs (ENST00000394742, NONHSAT089447, NONHSAT021545, NONHSAT041499) were positively related to negative coping style. Positive coping style scores in higher-expression of PR4 and PR6 subgroup were significantly lower than those in lower-expression subgroup. While on the other hand, negative coping style scores in higher-expression of NONHSAT089447, NONHSAT021545, NONHSAT041499 subgroup were significantly higher than those in lower-expression subgroup. In conclusion, three lncRNAs (NONHSAT089447, NONHSAT021545, NONHSAT041499) were over-expressed in schizophrenia patients, probably playing a role in the epigenetic process of choosing coping style.

Aim. To assess the results of the activities of the neurosurgical service of the Republican Research Center of Emergency Medicine (RRCEM) over a twenty-year period of operation with an analysis of the results of neurosurgical care for patients with arteriovenous malformations of the brain (AVM). Material and Methods. The analysis was carried out of 54 patients examined and operated on for AVM, in the period from 2001 to 2020, who were treated at the Department of Adult Neurosurgery of the RRCEM. Results. The basis of our principle of a differentiated surgical approach in the treatment of AVM is the determination of the AVM grading according to the Spetzler-Martin and Lawton-Young scales. Limiting only microsurgical AVM resection is advisable for AVMs – I and II grades according to the Spetzler-Martin and Lawton-Young scales. For patients with high grades of AVMs – grade III and more, it is more expedient to use a combined technique, and with deeply located AVMs, endovascular embolization.

Published: January 2022

The research recorded that growth hormones are effective in malignant cell formation and metastasis in many types of cancer. The release of vascular endothelial growth hormone has regulated by vascular endothelial growth hormone receptors. Therefore, inhibition of the vascular endothelial growth hormone receptor is important in hindering the formation of cancerous cells and metastasis. Many new molecules have been synthesized for fighting against cancer and their anticancer activity has been investigated. Since the first synthesis of N-heterocyclic carbene molecules, much bioactivities research has been performed and some of them have become drugs that are used in treatment procedures. Due to the difficulty and cost of the methods used to examine the bioactivities of molecules, foresight regarding the activities of possible active molecules is valuable. It is useful to make these preliminary evaluations in-silico methods. Comparing the results of the experimental analysis with the in-silico results is important in terms of having information about the validity of computational methods. In this study, N-heterocyclic carbene type benzimidazolium cations were analyzed with DFT/TDDFT computational methods and molecular docking for vascular endothelial growth factor receptor-2.
