Authors: Zhang Jian , Luo Chaoqiong , Wang Liping
Published: December 2021

Aiming at the selection of modern auto parts design schemes, an evaluation method of automobile parts design scheme for intelligent manufacturing is proposed. Considered the environment-friendly factors and traditional manufacturing factors, the evaluation index system of automobile parts design scheme was established, which taken technology, environment, economy and quality reliability as the first level evaluation index, and 12 second level indexes under the first level index. The game theory method was used to comprehensively consider the proportion of subjective and objective weights to determine the composite weight of each index. Aimed at the certainty and uncertainty of the evaluation index, the set pair analysis relative closeness method was used to calculate the composite weight and established the model. Three sets of automobile panel design schemes of a company were selected, and the mathematical model was used to calculate them. With the help of C language program, the advantages and disadvantages of the three design schemes were evaluated, and the optimal scheme was obtained. The calculation example proves that the method is true and effective, conforms to the background of modern intelligent manufacturing, and the calculation is simple, and has good feasibility and practicability.

Published: December 2021

The traditional mean shift algorithm used fixed kernels or symmetric kernel function, which will cause the target tracking lost or failure. The target tracking algorithm based on mean shift with adaptive bandwidth was proposed. Firstly, the signed distance constraint function was introduced to produce the anisotropic kernel function based on signed distance kernel function. This anisotropic kernel function satisfies that the value of the region function outside the target is zero, which provides accurate tracking window for the target tracking. Secondly, calculate the mean shift window center of anisotropic kernel function template, the theory basis is the sum of vector weights from the sample point in the tracking window to the center point is zero. Thirdly, anisotropic kernel function templates adaptive update implementation by similarity threshold to limit the change of the template between two sequential pictures, so as to realize real-time precise tracking. Finally, the contrast experimental results show that our algorithm has good accuracy and high real time.

Published: December 2021

In the article was found that the planned location of new or expansion of existing production clearly coincided with the movement of certain segments of the population to these regions for employment, examining and analyzing the problems of migration of the population of the former USSR.

The researches of the Russian town-planners Bocharov Y.P.,       Belousov V.M., Vladimirov V.V., Maloyan G.A., Lezhava I.G. and other are devoted the problems of development of the theory of settlement with loss of planning component in development of systems of settlement and general plans of cities in new market (social and economic) conditions.

Leading domestic urban planners have devoted their research to the problems of the development of the theory of settlement in Ukraine, the system of settlement and the development of master plans in modern market conditions (1992-2014). Some of them are Filvarov G.K., Yezhov V.I.,   Demin M.M., Lavrik G.I., Repin V.M., Timokhin V.O., Shkodovsky Y.M., Rudnitsky A .М. and other.

The article presents the stages of formation of production relations, social, economic, architectural and spatial evolution under the pressure of migration processes, based on the analysis and research:

The formation of the labor market (places of employment) in the development of industry, transport links and resettlement (early nineteenth - early twentieth century).

Urbanization of cities in the early twentieth century due to migrations (free labor) from near and far agglomerations.

Urbanization of the late twentieth century due to the release of labor (the collapse of the collective and state farm system).

Under the pressure of migration and transport processes the compositional and planning spatial structure of the city is determined by the following aspects: the hierarchy of the city in the general network of settlements; the level of the city's public transport network; mobility of city residents; location of attractive objects for migrants in the city planning structure; socio-demographic characteristics of residents. Territories of cities with developed production are becoming the poles of industrial industry with the latest technologies, as well as centers of business.

Published: December 2021

The aim of the research is to identify the compositional methods of using art glass in the interiors of public buildings in order to increase their aesthetic expressiveness. In the article the information on the history of art glass development is given. According to the results of the historical analysis, it is concluded that new directions of glass application arose with the development of new technologies of glass production and processing - this process continues to this day. An overview of the state of study of the problem, in particular the research of Kazakova L.V., F.Petryakova, Som-Serdyukova O.M., Daineko V.V., and identified the main areas in which research is conducted. The physical properties of glass and its types by technological features are considered. A historical overview of the development of gutnitsy on the territory of Ukraine. The two main trends in studio glassmaking to date have been identified and a conclusion has been drawn about the evolution of art glass from the subject form to the art object. The current state of art glass formation is characterized by associativity, metaphoricalness, and increased decorativeness. The classification of art glass according to the function of application in public interior is carried out. The basic compositional methods of placing art glass in the space of public interior are revealed. Three degrees of integration of art glass with elements of architecture are formulated: the decor on architectural elements, as a part of architectural elements, is directly an architectural and constructive element. Examples of objects that demonstrate the integration of art glass with architectural elements are given. Henri Matisse's stained glass windows in the Dominican Sisters' Chapel in Mans, France, are described as an example of the use of the "rhythm" compositional technique and Dale Chihuly's glass garden gallery in Seattle with a glass installation that dominates the pavilion. It is concluded that the choice of compositional methods of including art glass in the interior space depends on many factors - the functional purpose of the room, the specifics of space, its size, etc. and should take into account aspects of its psychological impact on man, principles of structural and compositional organization and features life processes.

Published: December 2021

Endothelial dysfunction as well as hypercoagulability have been described as the initial triggers of atherosclerosis and cardiovascular damage and have been associated with subclinical hypothyroidism (SHC). The aim of this research was to determine the concentration of nitric oxide (NO), fibrinogen and circulating lipids in patients with subclinical hypothyroidism and to correlate these variables with thyrotropin (TSH) concentration to establish their possible association with the development of cardiovascular damage. A descriptive, cross-sectional, correlational study was conducted at the IESS Hospital in Riobamba, Ecuador, in the period from January 2019 to September 2021. Ninety-five subjects were studied (65 patients with CAH and 30 controls). The concentration of total cholesterol, triglycerides, HDL cholesterol and LDL cholesterol, TSH, free thyroxine, ON and fibrinogen were determined. Results: We found a decrease in the concentration of ON (p<0.001), accompanied by an increase in the concentration of total cholesterol (p<0.0001), LDL cholesterol (p<0.01) and fibrinogen (p<0.0001) in patients with CAH vs. controls. A negative correlation (p<0.0001; r= -0.5020) was observed between TSH and ON and a positive correlation (p<0.0001; r= 5412) between TSH and plasma fibrinogen in patients with CAH. Conclusion: patients with CAH showed a decrease in serum ON levels and an elevation in plasma fibrinogen concentration. Both measurements correlated significantly with TSH concentration. These parameters associated with an increase in total cholesterol and LDL cholesterol could favor vascular dysfunction, the development of atherosclerosis and consequent cardiovascular damage.

Authors: Oyeka Amechi , Amasiani Rose
Published: December 2021

This study was carried out to determine the fungal and mycotoxins contamination of 36 Wheat (Triticum aestivium) samples purchased randomly from the seller of the agricultural produce in local markets of Anambra State, Nigeria. Results from the studies showed that two hundred and three fungal isolates consisting of 18 species of moulds and 5 species of yeasts contaminated the wheat samples at varying degrees. For moulds, Aspergillus species contaminated the samples  mostly with (28) isolates followed by Penicillum species (19) isolates while Verticillium species and Cladosporium species had equal least contaminations with (3) isolates each. Among the yeast species, Candida rugosahad the highest number of contamination with (37) isolates followed by Cryptococcus laurentii (31) isolates while Candida stellatoides (9) isolates had the least contamination. Twenty-four fungal metabolites were also recovered. The concentration of trichothecene mycotoxin Deoxynivalenol (2067µg/kg), a protein synthesis and cell proliferation inhibitor in animals exceeded the maximum acceptable limits for human consumption. It can be deduced therefore that wheat circulating in Anambra State, Nigeria are variously contaminated with different xerophilic moulds and mycotoxins which can exert adverse health problems to consumers.

MEGXIT IN CONTEMPORARY MEDIA AND INTERNET DISCOURSES
Authors: Kornilieva Liliia
Published: December 2021

Every language preserves historic realia, reveals peculiarities of the geographical position of a particular country, main traits of the national character, and the overall cultural code of every nation speaking it. The language also describes all new realia and phenomena, and neologisms are coined all the time. «Brexit», «Megxit», «To Meghan Markle» are relatively new words in the English language. Romanticized image of a beautiful and tender princess, happily married to her royal Beau − a handsome, valiant and dashing young man is one of the most popular icons in European folklore. But modern fairy-tales are not that much simple. One omniscient author is definitely not enough, and millions of other on-line commentators contribute to the main line of the story, describing the prince and his princess, and often calling them names. Surprisingly as it may seem, the saying «My home is my castle» becomes not true, and the palace walls often shudder from rumors and insinuations, racial slurs and undertones. Under the circumstances a former friend often becomes a foe, compatriots become the invaders, responsible for a massive intrusion and violation of a basic human right for privacy. The main characters feel unhappy and the fairy tale soon becomes a thing to endure. These are the realia of our modern culture, with its etiquette and netiquette, black PR, on-line trolls and getting bad press. The Sussex family often cites racism as the main cause of all their troubles, but the plethora of various texts can reveal much more than just racism and related inequities. Personal qualities of the Duchess, her American origin and professionalbackground contribute to a massive cultural clash, and the new word «Megxit» appears, adding new shades of meaning to the «happily ever after» from the fairy tales. The article centers on the issues causing Megxit, and the texts give newinsight to a famous and well-known story.
INTER- AND GENERATIONAL DISCOURSE AS THE CORNERSTONE OF THE EVERYDAY FROM THE PERSPECTIVE OF FICTION
Authors: Sadovskaya Ekaterina
Published: December 2021

Inter- and generational interaction takes place in everyday communication and serves as the basis of any society as it forms, regulates and maintains the existence of society by collecting, preserving and transferring knowledge and experience from generation to generation. The interaction of generations is practice based; it rationalizes the actions of individuals in society relying on common sense for the purpose of preserving the descendants and turning individual experience into objective knowledge for the following generations. This is done in everyday mundane interaction of generations. It is fiction that has accumulated this experience; it demonstrates not only the abundance of inter- and generational interaction but also its daily presence and vital character. The most vivid description of such generational or intergenerational interaction is seen in fictional works dealing with the relationships in the family, growing up of children and grandchildren and in novels of morals.
THE DISCOURSE-AND-NARRATIVE POLYPHONY OF THE QUOTIDIAN AND THE PUBLIC-RELATED IN IAN MCEWAN’S SATURDAY (2005)
Authors: Sushko Sergii
Published: December 2021

In the English-written literature, the «one day novel» genre modification is represented by an appreciable number of novels. V.Woolf’s Mrs Dalloway and J. Joyce’s Ulysses are the famous paragons of the subgenre. Ian McEwans’ Saturday also joins this category. The novel’s protagonist’s inner speech intensification as well as retrospective inclusions and digressions help the narrator to go beyond the conventional boundaries of the «one day novel» genre variety. The research undertaken in the given paper pursues exploration of of the possibility of combining the discourse and narrative elements of the literary text into one narrative entity. In the Ian McEwan’s circadian novel Saturday, the professional discourse of the neurosurgery as well as other discourses are skillfully and masterfully interwoven into the story-action-and-event governed textual terrain, that is into its narration. In the paper, the polysemantic structure of the terms «quotidian», «discourse», «narrative» has been analyzed. Also, such aspectual narratives of the novel as the quotidian narrative, medical, psychological, literary, mass media, topographical, musical, sports ones have been identified and some of them explored. Also, the plot-building function of the Neo-Victorian code of the novel has been specified and the Leitmotiff recurrence of some quotations, allusions and reminiscences has been dwelt on. In the paper, the principle of narrativization of a discourse is hypothesized; in keeping with it, the discourse-containedinformation is delivered through the action-and-event-based narrative. The discourse-governed knowledge is not distanced from the narrative, both are fused into one narrative whole. This principle accounts for a polyphonic interplay of discourses and narratives in the novel treated here.

Published: December 2021

For many international students the prospect of employment in overseas locations post-study is a strong desire. The concept of employability has infiltrated the literature but little is known about how volunteering experiences might impact international students’ preparedness for work placement during their programs of study. Using theoretical framing related to types of employability literacies, this paper shares data from interviews with international students who volunteered. Findings revealed several themes aligning with linguistic proficiency, cultural awareness, attitudes and mindset, and vocational literacies. Additional themes such as hospitable relationships and building trust were also revealed which could relate to sustainable citizenship. Many benefits result from volunteering experiences for both international students and their hosts, but more work is needed to support hosts through cultural awareness programs and international students due to their study commitments and limited time.

Authors: Kholidina Imanda Harahap  , Harry Agusnar  , Sumadhi Sastrodihardjo
Published: December 2021

Resin komposit sebagai bahan restorasi di dalam mulut akan selalu berkontak dengan saliva sehingga terjadi penyerapan air ke dalam resin komposit. Penyerapan air pada resin komposit dapat menurunkan sifat fisis dan mekanis serta menimbulkan kelarutan elemen resin komposit sehingga akan memperpendek masa pakai dan menimbulkan toksis. Penelitian ini bertujuan untuk membandingkan besaran serapan air, kedalaman dan kecepatan penyerapan air antara resin komposit mikrohibrid dengan nanohibrid setelah direndam di dalam saliva buatan. Sampel yang digunakan pada penelitian ini dibuat dari resin komposit mikrohibrid dan nanohibrid berbentuk tablet berdiameter 15 mm dan tebal 1 mm dengan pengerasan sinar tampak biru. Penelitian dilakukan dengan merendam sampel di dalam saliva buatan selama 2, 4, 6, dan 8 jam. Besaran serapan air dihitung dari perubahan berat yang terjadi dan kedalaman penyerapan air diukur dengan menggunakan mikrograf mikroskop. Kecepatan penyerapan dihitung dengan membandingkan kedalaman penyerapan air dengan waktu perendaman. Hasil yang diperoleh memperlihatkan serapan air pada resin komposit mikrohibrid 2,69, 5,71, 5,88, dan 5,96% sedangkan pada nanohibrid 5,34, 3,76, 3,09 dan 2,83%. Hasil pengukuran kedalaman penyerapan air pada resin komposit mikrohibrid 3054,98, 6125,42, 8529,94, dan 8930,01µm sedangkan pada nanohibrid 7830,77, 6941,29, 6844,67 dan 6120,53µm. Hasil penghitungan kecepatan penyerapan air resin komposit mikrohibrid adalah 1527,45, 1531,36, 1421,66 dan 1116,18µm/jam sedangkan pada nanohibrid 3915,39, 1735,32, 1140, 78 dan 761,32µm/jam. Analisis statistik menunjukkan perbedaan signifikan (p≤ 0,05) pada ketiga variabel tersebut antara kedua jenis resin komposit yang diuji. Dapat disimpulkan, serapan air dan kedalaman penyerapan resin komposit mikrohibrid lebih besar dibandingkan nanohibrid sedangkan kecepatan penyerapan air pada kedua jenis resin komposit mengalami penurunan.

Authors: Wandania Farahanny  , Trimurni Abidin  , Harry Agusnar
Published: December 2021

Penggunaan bahan adhesif pita serat penguat polietilen dengan resin komposit sebagai pasak buatan semakin banyak diminati. Pemasangan pasak ini tidak membutuhkan pelebaran saluran akar yang lebih banyak sehingga dapat mengurangi risiko terjadinya fraktur akar. Wetting resin dipakai sebagai wettability untuk meningkatkan perlekatan interfasial. Terkadang para klinisi sering menggunakan flowable resin sebagai penggantinya. Penelitian ini bertujuan untuk mengetahui ketahanan fraktur penggunaan pita serat penguat poli etilen anyaman braided dan locked-sticthed threads sebagai pasak buatan pada restorasi pasca perawatan endodonti dengan aplikasi wetting resin dan flowable resin. Empat puluh gigi premolar mandibular yang telah diekstraksi dan memiliki ukuran sama dibagi menjadi empat kelompok. Kelompok A (locked-sticthed+wetting resin), B (locked-sticthed+flowable resin), C (braided+wetting resin) dan D (braided+flowable resin). Setelah pemotongan mahkota dan perawatan endodonti dilakukan pemasangan pasak buatan. Pita dibenamkan ke dalam semen resin dual cured dan dilanjutkan dengan pembentukan mahkota dari resin komposit. Setelah thermocycling, dilakukan uji tekan searah aksial gigi dengan kecepatan 0,5mm/detik sampai terjadi fraktur menggunakan Universal Testing Machine. Nilai beban fraktur dan pola fraktur yang terjadidicatat. Hasil uji statistik Anova menunjukkan tidak terdapat perbedaan signifikan pada ketahanan fraktur pasak buatan pita serat penguat dengan pola anyaman dan wettability yang berbeda (p= 0,367). Dengan adanya keterbatasan penelitian ini, pola fraktur pasak fiber anyaman locked-sticthed threads dan braided dengan wetting resinmenunjukkan 80-90% mudah direstorasi kembali. Sebagai kesimpulan, penggunaan pita serat penguat polietilen sebagai pasak buatan dengan anyaman berbeda memiliki ketahanan fraktur yang sama. Akan tetapi, pola fraktur pada pasak yang menggunakan wetting resin lebih mudah direstorasi kembali dibandingkan dengan flowable resin.

The skin problem often found on adolescents is acne vulgaris. The pathogenesis of acne vulgaris is multifactorial, from increased production of sebum, hyperproliferation of pilosebaceous follicles, colonization of Cutibacterium acnes, to inflammation process. The elevated sebum production which is often linked to oily skin type could result in acne vulgaris in adolescents. According to Baumann Skin Type, one of the parameters in categorizing skin type is having either oily or dry skin. Acne vulgaris is also found on dry skin. This research aims to find the association between skin types and acne  vulgaris. It is an analitic research with cross-sectional method. The data were acquired from 93 students of SMA Santo Thomas 1 Medan who fulfilled the inclusion criteria with stratified random sampling method. The collection of data were primarily carried out with dermatology examination and Baumann Skin Type questionnaire to determine the skin types. Then, they were analyzed with Chi-square test to see the relationship between skin types and acne vulgaris.      The obtained results show that 73 (78,5%) out of 93 students suffered from acne vulgaris with predominance being female (39,8%) than male (38,7%), and those in 15-year age group (38,7%). The most commonly observed skin type on samples is oily skin (79,6%). The bivariate analysis with acquired p-value of 0,002 (p<0,05) led to a conclusion that there is a significant association between skin types and acne vulgaris.

Stroke is the third highest cerebrovascular disease in the world with high mortality and disability rate that is mostly dominated by ischemic stroke. Genetic factor that had been reported to have an indirect effect in increasing the incidence of ischemic stroke is ACE gene polymorphism. ACE gene polymorphism is characterized by the insertion marked by letter (I) or deletion marked by letter (D) on intron 16, chromosome 17. ACE gene polymorphism has drawn a lot of attention from scientists and had been reported to have an indirect effect in increasing the ischemic stroke incidence through pathogenesis of hypertension and atherosclerosis. In this study, 78 subjects of ischemic stroke consist of 43 subjects with hypertension and 35 subjects with normotension. I allele of ACE gene polymorphism was more dominant than D allele in hypertensive ischemic stroke patients (72.1% > 27,9%) and this dominance was also seen in the incidence of hypertension vs normotension (55.4% > 44.6%). However, the correlation of ACE gene polymorphism with the incidence of hypertension was not statistically significant when compared based on its genotype (p=0.280) and allele (p=0.948).

Abstract. Background. Premature canities is a terminology to describe a premature graying of hair before the age of 25 in Asians.The ethiopathogenesis of premature canities is still not fully understood, but there are risk factors associated to premature canities such as gender, family history, obesity, smoking, alcohol consumption, other disease, micronutrients deficiencies. Aims: to evaluate risk  factors that influence the incidence of premature canities in medical students of University of Sumatera Utara class 2016-2018. Methods: This research is an analytic research with the number of subjects are  80 respondents using bivariate and multivariate analysis using logistic regression test. Results: of the 80 respondents, 57 respondents (71,2%) had premature canities. Based on bivariate analysis, it was obtained p value ≤ 0,05 for family history and stress, Based on multiavariate analysis, it was obtained p value ≤ 0,05 for family history (p value = 0,000), which means family history is the most dominants factors for premature canities. Conclusion: there is a correlation between premature canities and family history and stress and Family history is the most dominant risk factors that associated to premature canities in medical students of University of Sumatera Utara class 2016-2018.

Background: Melasma and lentigo solaris are common, recurrent, and refractory acquired hyperpigmentation disorder. In spite of variety of therapeutic options available for this cosmetically disfiguring condition, the treatment of this condition remains a challenge. Azelaic acid (AA) is a depigmenting agent which acts by inhibition of DNA synthesis and mitochondrial enzymes, thereby inducing direct cytotoxic effects on melanocytes. Glycolic acid (GA) peel is one of the most versatile agents in the treatment of melasma and lentigo solaris. GA peels alone or in combination with topical hypopigmenting agents has shown encouraging results. However, there is paucity of controlled trial demonstrating the efficacy of GA peels in conjunction with topical AA.

Case: A 42-years-old female, works as a street vendor, came with dark brown spots on both cheeks, nose, chin and forehead that spreads to whole face since one year ago. She had a history of using contraceptives. From the dermatological examination, there were multiple well-circumscribed, irregular hyperpigmented macules that asymmetrical, with size ranging from lenticular to plaque on the maxillary, left buccalis, mentalis and frontalis region. We also found a numular dark brown hyperpigmented macules on right zygoma. She was diagnosed with melasma and lentigo solaris. The Melasma Area Severity Index (MASI) score was 25.6, which classified as moderate melasma. She was treated with 20% azaleic acid cream twice a day, broadspectrum sunscreen with SPF 50 and GA 20% peeling.

Result: After 6 weeks of treatment, there were significant  improvement in both melasma and lentigo solaris.

Hyperuricemia is an increase in blood uric acid levels. In the elderly cell damage occurs due to the aging process which can result in organ weakness, physical damage and various diseases such as increased uric acid levels. The purpose of this study is to determine the relationship between purine intake and the incidence of hyperuricemia in the elderly at the HISOSU Binjai nursing home. This research was conducted with an observational analytic research design using a cross sectional study. Samples were selected using the total sampling method and adjusted for inclusion and exclusion criteria. Data taken by weighing and recording food (in 1 day) Then assess respondent uric acid levels. This is done 3 times in the HISOSU Binjai nursing home. There are 32 research samples. Samples that experienced hyperuricemia as much as 40.6%, most of them consuming moderate-category purine source protein. The results of the chi-square test Pearson chi-squared t-test was 16.453 and p value < 0.001 (<0.05), it can be concluded as consumption of purine source protein associated with the incidence of hyperuricemia. The higher the purine intake, the greater the chance of getting hyperuricemia.

Published: December 2021

Background. Congenital abnormalities or congenital abnormalities are abnormalities that have existed since birth that can be caused by genetic and non genetic factors. The study of congenital abnormalities is called dysmorphology. Congenital abnormalities are one of the biggest contributors to death and morbidity in neonates, infants, and children. There were 7.9 million cases of congenital abnormalities and 3.3 million premature deaths due to congenital abnormalities in the world in 2013. In Southeast Asia it is estimated that cases of congenital abnormalities numbered 1,946,606 cases each year in 2013 according to WHO. In 2018, more than 8 million babies worldwide are born every year with congenital abnormalities. In the United States nearly 120,000 babies are born with congenital abnormalities each year. The cause of fetal congenital abnormalities due to genetic and non-genetic factors. Single gene mutations, balance disorders due to chromosomal abnormalities, and multifactorial abnormalities are included in genetic factors. Non-genetic factors can be caused by teratogen drugs (drugs, chemicals, infections, and maternal diseases that affect the fetus) and radiation. There are 5 risk factors that influence the occurrence of fetal congenital abnormalities, namely genetic, socioeconomic and demographic factors, environment, infection, and nutritional status. Aim. To determine the risk factors for congenital abnormalities in newborns at the Haji Adam Malik General Hospital and the University Hospital of North Sumatra in 2017-2019. Method. The design used by researchers uses a cross-sectional approach. The sample used was Patients with Congenital Abnormalities who were in the Human Rights Hospital and USU Hospital in 2017-2019. Result. The most influential risk factors for fetal abnormalities are maternal age, disease history, infectious history, and poor nutritional status. There are no results that can prove that the history of pregnancy affects the occurrence of fetal congenital abnormalities.
