Authors: Beaudoin Maria Laura , Torrents Milagros , Tittarelli María Florencia , Hamui Magali , Ibarra Mariano , Ferraro Mabel , Ferreira Juan Pablo
Published: April 2021

BACKGROUND:

Although intravenous insulin administration is the standard of care in diabetic ketoacidosis (DKA), subcutaneous insulin administration could be a suitable alternative in resource-limited settings, but pain caused by hourly insulin applications are limiting factors for using it, especially in children. We aimed to assess whether the use of a flexible subcutaneous catheter improves comfort in patients with DKA compared with the usual hourly injections’ treatment. We also compared the evolution of metabolic variables in patients with DKA using both insulin administration systems.

METHODS:

Randomized feasibility controlled open trial, comparing 2 ways (flexible catheter and steel needle) for the initial insulin administration in children with DKA, who were randomly selected to receive subcutaneous insulin by a flexible catheter or using standard needles. The main outcome was pain, assessed hourly and secondary outcome time to achieve ketoacidosis resolution.

RESULTS:

Twenty subjects were included (10 by group). There were no differences between groups in baseline lab values (glycemia, urea, sodium, bicarbonate and pH). Pain assessment at first insulin administration was significantly lower in the intervention group (4.5 vs 0 points; P = 0.001). Similar differences between both treatment arms were observed in every pain assessment. There were no differences between groups regarding the time elapsed to achieve ketoacidosis resolution. (11.4±4.3 vs 16±8.4; P = 0.12). No adverse events or DKA complications were observed.

CONCLUSIONS:

The use of a flexible catheter reduced the pain associated with subcutaneous insulin administration in nonsevere DKA. The flexible subcutaneous catheter could be a safe alternative for the treatment of uncomplicated DKA in resource-limited settings.
Revisiting Skeletal Dysplasias in the Newborn
Authors: Langston Seth J. , Krakow Deborah , Chu Alison
Published: April 2021

With over 400 reported disorders, the skeletal dysplasias represent a myriad of molecularly-based skeletal abnormalities. Arising from errors in skeletal development, the clinical spectrum of disease evolves through an affected individual’s life. The naming and grouping of these disorders are ever-changing, but the fundamentals of diagnosis remain the same and are accomplished through a combination of prenatal ultrasonography and postnatal physical examination, radiography, and genetic analysis. Although some disorders are lethal in the perinatal and neonatal periods, other disorders allow survival into infancy, childhood, and even adulthood with relatively normal lives. The foundation of management for an affected individual is multidisciplinary care. Medical advances have offered new insights into reducing common morbidities through pharmacologic means. This review summarizes the normal skeletal development and discusses the 3 most common skeletal dysplasias that can affect the newborn.

0
parameters were calculated and correlation with previously determined logPo/w values was examined. RP-HPLC system IV, which consisted of cyano column and methanol–water mobile phases (50:50, 60:40, 70:30, and 80:20, v/v), was selected as the most reliable for lipophilicity prediction and used for the analysis of chromatographic behavior of remaining fourteen 17β-carboxamide glucocorticoids. Quantitative structure-retention relationships analysis was performed and PLS(logkw) model was selected as the most statistically significant. On the basis of selected model and interpretation of corresponding descriptors, new derivatives with higher logkw values and higher expected lipophilicity were designed.
Perceptions of On-Premise Commercial Sign Regulation Codes for Beauty, Interest, and Order by Designers and Non-Designers
Authors: Rakestraw Maleah , Crawford Pat , Lee Eunsil
Published: April 2021

Regulation has long since guided urban growth, and it is essential for municipalities to construct regulation that is conducive to creating visually stimulating public spaces. Minimal scientific research has been conducted on the impacts of commercial signage and the varying arrangements created by different sign regulations in regard to perception (Jourdan, Hurd, & Hawkins, 2013; Portella, 2014). With the rise of public involvement in planning (Lane, 2005; Sanoff, 2000), it is essential that designers and non-designers coordinate to develop sign controls that contribute to urban growth. This research studies the differences and similarities in perceptions of planning and design professionals and non-designers to aid in the development of future, more positively perceived, signage regulation. By using visual models presented in the form of a survey, findings show both similarities and differences between these groups in their assessment of signscapes regarding communication, perceptions of characteristics like beauty, interest, and order, an overall preference toward highly structured codes, and a difference in harshness of evaluation.
DCM: D Number Extended Cognitive Map. Application on Location Selection in SCM
Authors: Zhou Lian , Xiao Fuyuan
Published: April 2021

Offshore outsourcing is a widely used management technique for performing business functions with the aim of reducing labor and transportation costs. The selection of locations has a significant influence on the supply chain’s resilience and qualities, but the influence of multiple external factors on the supply chain’s performance in local places in a complex and uncertain environment has not been examined. In this study, we investigated the influence of external factors in a highly uncertain and complicated situation in which relationships between external factors and supply chain resilience are complicated. Furthermore, we proposed a novel model to select locations from a comprehensive perspective. Specifically, the fuzzy cognitive map (FCM) is utilized to simulate the dynamic influence process where the adjacency is aggregated by D numbers. The weights of different resilience capabilities are considered from the perspective of maximizing benefits by using the decision-making trial and evaluation laboratory-analytic network processes (DEMATEL-ANP) model. By comparing the distance to the ideal solutions, we selected the best alternative location. Our results differ from the general case, which reveals that the weights of different capabilities influence selections.

Published: April 2021

Background: Toddlers aged 24-59 months are experiencing a very rapid growth process; however, they are also prone to have nutritional problems, including stunting. Stunting occurs mainly within the first 2 to 5 years of life. The main cause is a lack of knowledge on toddler’s nutritional intake among women of childbearing age. This study aimed to explore the effect of health education using video media on the knowledge about stunting among women of childbearing age.Methods: This was a quantitative, experimental study with one group pretest-posttest design conducted in July-November 2019 on women of childbearing age in the working area of Public Health Center (Pusat Kesehatan Masyarakat, Puskesmas) Jatinangor, West Java, Indonesia. Respondents were recruited using the Multistage Random Sampling according to the inclusion criteria. A pre-test was administered before the health education session on stunting and a post-test was administered afterwards. Data collected were then analyzed using the Wilcoxon Test.Results: In total, 211 women were included. Education video on stunting was proved to significantly increase the respondent's knowledge on stunting (p=0.000, r value=0.690).Conclusion: Health education video clearly increases knowledge on stunting among women of childbearing age. Thus, video medium can be used as a preferred method for disseminating knowledge on various health topics.
Price Effects in the Evaluation of Investment Projects
Authors: Suslov V.I. , Novikova T.S. , Gulakova O.I.
Published: April 2021

In the context of globalisation, there is a need to assess the difference between domestic and world price effects as an im- portant component of the economic analysis of investment projects. We developed an integrated approach to measuring the differences between commercial and public efficien cy (indicati ng pri ce effec ts) and substantiat ing the applicat ion of specific mechanisms for implementing relevant projects based on the principles of public-private partnership. We propose to estimate price effects using three interrelated models: financial and economic model, input-output multi-regional model, and econometric model. The combination of these models allows analysing large investment projects considering their influence on the develop- ment trends of the global, national and regional economy. This methodology was tested on the example of a real regional project for the construction of the Eastern Siberia — Pacific Ocean (ESPO-2) oil pipeline. The results show that the share of price effects amounted to more than 35 % of net present value within the framework of public efficiency, confirming their high significance. Tax price effects have the largest share in the structure of the price effects. Indirect price effects of the considered project are less significant. The research results have confirmed that the identification of indicators of public efficiency and in-depth analysis of price effects increase the validity of the assessment of regional infrastructure projects. In the future, we plan to use the proposed methods as an integral part of a comprehensive assessment of large-scale production, transport and research infrastructure projects.
Fisiopatologia del blocco atrio-ventricolare di I grado molto marcato: quando può essere ragionevole l’impianto di pacemaker?
Authors: Campana Andrea
Published: April 2021

Un intervallo P-R di 200 ms sull’elettrocardiogramma è indicato come limite superiore della norma, ma la definizione di BAV di I° grado varia da > 200 a ≥ 220 ms. La prevalenza di un intervallo P-R >200 ms è dell’1-2% nella popolazione generale ed aumenta con l’età. Il significato clinico di un intervallo P-R superiore a 200 ms è considerato generalmente benigno, ma alcuni studi suggeriscono l’opposto e cioè che il BAV di I° grado possa essere associato con un aumentato rischio di fibrillazione atriale, scompenso cardiaco, impianto di pacemaker e mortalità totale. Le cause conosciute di BAV di I° grado sono numerose ed includono cardiopatie congenite, malattie degenerative del sistema di conduzione, cardiomiopatie, connettiviti, malattie infiammatorie ed uso di farmaci. Nella pratica clinica, il BAV di I° grado marcato (P-R > 300 ms) non è comune e la sua prevalenza è < 1/10000. Pur trattandosi di un reperto piuttosto raro, un intervallo P-R > 300 ms può causare sintomi la cui risoluzione potrebbe richiedere l’impianto di un pacemaker definitivo; i sintomi sono legati ad una sensibile alterazione temporale delle componenti del riempimento ventricolare, configurandosi un quadro emodinamico che viene definito come “pacemaker-like-syndrome”. Il BAV di I° grado costituisce l’1.6% delle indicazioni ad impianto di pacemaker in Italia, ma è verosimile che l’associazione con altri disturbi della eccito-conduzione possa, nella maggior parte dei casi, contribuire a rafforzare l’indicazione, essendo veramente poco frequente l’impianto di un pacemaker nel BAV di I° grado esclusivamente per motivazioni di tipo emodinamico.
Problematiche aritmologiche in cardio-oncologia: il QT lungo e la morte improvvisa
Authors: Carbone Vincenzo
Published: April 2021

Numerosi farmaci utilizzati per il trattamento dei tumori hanno la capacità di prolungare la ripolarizzazione ventricolare e, conseguentemente, l’intervallo QT, generando un’aumentata suscettibilità allo sviluppo di Torsione di Punte e alla morte improvvisa. Sebbene si tratti di un evento molto raro, la TdP è prognosticamente rilevante ed è di fon-damentale importanza prevenirne la comparsa nei pazienti oncologici, selezionando in modo accurato le opzioni terapeutiche, evitando interazioni farmacologiche pericolose e ottimizzando il contesto clinico ed elettrolitico.
Principali farmaci antitumorali: quali e perché interessano il cardiologo
Authors: Barni Sandro
Published: April 2021

La cardiotossicità da farmaci antitumorali è diventata un importante problema clinico per i cardiologi e per gli oncologi. La disfunzione ventricolare sinistra e lo scompenso sono i quadri più rilevanti ed i meglio conosciuti, ma non bisogna dimenticare altre forme di tossicità come l’ipertensione, il tromboembolismo, le pericarditi, le aritmie e l’ischemia mio-cardica. Il loro trattamento non è sempre identico a quello usato nei pazienti non oncologici poiché la patogenesi ed il quadro clinico sono diversi, ma soprattutto perché la gravità del tumore e la prospettiva di vita richiedono di non so-spendere il trattamento antiblastico. Da qui nasce la necessità di una stretta collaborazione tra cardiologo e oncologo per preservare la qualità di vita del paziente, bilanciando il rischio di cardiotossicità e il beneficio della terapia oncologica.
Activity-Related and Sociocultural Grounds for Foreign Language Education of Adults who Lack Expressed Motivation for Cognitive Activity

Published: April 2021

The paper considers the problem of forced rather than self-actualized teaching of a foreign language to students, educators and representatives of other practical fields of activity. Theoretical and methodological backgrounds for solving this problem are revealed on the basis of the humanistic and activity-based traditions of psychological and pedagogical knowledge. Activity-related traditions are analyzed in regard with the potentialities of appropriate approaches to learning to stir cognitive interest while educational process. Humanistic traditions designed to individualize education are explored in the context of psycho-corrective capabilities of educational activity, its conformity to the world outlook, cultural needs and psychological characteristics of a learner. The practical side of this study consists of methodological recommendations on the application of Baitukalov’s method of teaching foreign languages. Within the framework of Baitukalov’s methodology, the activity-related aspect of sociocultural foreign-language immersion is actualized through feature films. Fragments from feature films are used for the humanization of education as well. In the paper it is also substantiated that the fragments of motion pictures recommended for memorization through role playing not only contribute to the development of the communicative competence, but also make the psycho-correcting effect on the learner’s consciousness. The paper makes emphasis on fairy-tale stories, positive situations from films, where heroes overcome external circumstances successfully and change and grow personally. Besides, a characterization of a number of feature films is given. The criteria for the selection of feature films should be based on the individual characteristics of a person. It is recommended to unite the efforts of specialists for the experience exchange of using the feature films potential. The provision of «ecological safety» (that concerns ethics, moral, etc.) and aesthetics while selecting the certain fragments of film production for education purposes is asserted as the essential problem of the noted experience exchange. Further development of Baitukalov’s methodology is suggested in the aspect of the teaching potential of feature films, as well as in increasing the efficiency of cognitive activity at the expense of equal time intervals between key semantic units (words, images, etc.) with at least threefold repetition of key information

Authors: Zhansakova Kymbat S. , Russkikh Gregory S. , Eremin Evgeny N.
Published: April 2021

This work is devoted to identifying the patterns of influence of the vulcanization accelerator N-cyclohexyl-benzothiazyl-sulfenamide (CBS) on the technological, physico-mechanical, and thermo-physical properties of vulcanizates based on styrene-butadiene rubber. It was found that a decrease in the content of the vulcanization accelerator decreases the maximum torque, and a noticeably longer time is required for optimum vulcanization in the absence of CBS. The thermal conductivity in vulcanizates increases with a decrease in the accelerator concentration due to changes in the structure and molecular mobility of kinetic units. Physico-mechanical indicators increase with a decrease in the concentration of CBS, this is due to a decrease in the apparent density of porous rubbers

Game Graph and Formats Approach for Mixlingual Data Ontology for Geological and Marketing Tasks
Authors: Skornyakova Ekaterina S. , Lichargin Dmitry V. , Polunian Pavel V.
Published: April 2021

The paper introduces a new concept – trans-forest. A forest is a complex of additional connected trees. The skeleton of the graph is the basic multi-hierarchy. Subjects and “forces” are sources of moves on the playing field of the trans-forest based on the rules of the generative grammars of Montague. Each move of all generative grammars is synchronized with the meta-generative grammar – the “daemon of time”. Each turn over a trans-forest can be done by moving the present marker on the time tree to the “Next” position. Particular attention is paid to the format tree and trans-connections between trees and its levels, since it is the format tree that determines human behavior in certain situations. An algorithm of evolutionarily justified expansions is proposed, the purpose of which is to ensure well-being for the subject himself and other subjects. The proposed trans-forest model is intended for modeling educational, language IT marketing, geological and other situations from the point of view of graph theory and game theory

Customer satisfaction is a vital component of service organisations that are significantly related to service quality. One of the electronic service quality that has to be prioritised, is website quality. Therefore, this study will determine the influence of electronic service quality and electronic word of mouth (eWOM) toward repurchase intention on e-commerce in Indonesia. Data were obtained from Google Form Online Questionnaires which were distributed through a short-link in WhatsApp, LINE, and Twitter applications during April 2019. This study applied the purposive sampling method where 458 qualified samples were matched to the specific criteria. Structural Equation Model (SEM) supported by LISREL software was used to analyse the data. The findings show that there are positive and significant influences of electronic service quality of pleasant and utilitarian dimensions to eWOM construction and repurchase intention. This research suggests managerial implication to e-commerce industry practitioners to reduce Tokopedia and also Instagram as the benchmark of electronic-based service quality. The managerial implication covers observing and adopting mobile application service quality aspects, service online review, and virtual communities. Besides, it is significantly suggested for future studies to explore more specific contexts of pleasant and utilitarian electronic service quality dimensions as in the B2B e-commerce, B2C e-commerce, and G2C e-commerce. Keywords: Electronic service quality, eWOM, repurchase intention, e-commerce, tokopedia.

Seeking health information is becoming more convenient with various health resources online. It would be beneficial to explore the perception of individuals’ health status concerning health information seeking and eHealth literacy. With government employees in Putrajaya found to be at high risk of Non-Communicable Disease (NCD), based on the high rate of obesity, it is beneficial to explore the factors associated with OHISB among this population to ensure adequate attainment and sharing of health information and self-management resources. The Comprehensive Model of Information Seeking (CMIS) is used to measure the factors that influence online health information-seeking behaviour (OHISB). Based on previous studies, the CMIS is commonly used to examine cancer patient’s information seeking on health information behaviour. However, this paper will be focusing on government employee’s behaviour in using online information as to their health reference. Previous studies have shown that information seeking has resulted in changes in the behaviour of cancer patients. It is believed that the outcome of this study will be beneficial in terms of developing strategies to encourage a healthier lifestyle among this population to prevent the occurrence of NCDs. Therefore, this paper elaborates on some of the theories used in previous studies to enrich individual and community online health information-seeking behaviour and health knowledge dissemination. The findings of this study show the direct relationships between trust in internet health and eHealth Literacy were significant towards OHISB. However, the direct relationships between direct experience, salience, unmet information needs and self-efficacy belief towards OHISB were not significant. Keywords: Comprehensive model of information seeking, online health information seeking behaviour, non-communicable diseases, ehealth literacy, government employees.
WAYS TO RESOLVE AND OVERCOME CONFLICTS IN CRIMINAL LAW OF UKRAINE
Authors: Oliinyk O.
Published: April 2021

The purpose of the article is to find the best ways to resolve conflicts in the criminal law of Ukraine. Methods. Methodological tools are selected in accordance with the purpose, specifics of the object and subject of research. The main one is general dialectical method of scientific knowledge of real legal phenomena. Special research methods used in the study are: the method of systematic analysis, formal legal, interpretation of law, comparative law, modeling. The theoretical basis of the study is the latest scientific works in the chosen field of research. Results. As proved during the analysis of the legal literature, there is the following list of effective ways to resolve and prevent conflicts in law, which can be extrapolated to the field of criminal law: 1) unification of law; 2) harmonization of law; 3) approximation of law; 4) clear delineation of powers of public authorities; 5) monitoring of normative legal acts; 6) creation of model laws; 7) interpretation of law; 8) improvement of legislation. Conclusions. As a result of the study, it is proposed to apply different principles to overcome conflicts depending on their type (in particular, "a special law repeals a general law", "a later law cancels an earlier one", "the next general law does not cancel an earlier special law of similar legal force"). Types of "conflict rules" in the sources of criminal law are presented primarily depending on the specific type of such sources. Modern legislation, including criminal, contains virtually no rules aimed at overcoming intersectoral conflicts, but conflicts of law in various areas of Ukrainian law create significant problems in law enforcement.

Authors: Baranova V.A. , Dubovskaya E.M. , Savina O.O.
Published: April 2021

Objective. Analysis of the resources for overcoming difficulties by students in connection with the new life experience in the first weeks of self-isolation and distance learning in the context of the CO¬VID-19 pandemic.
Background. The study is focused on identifying the current psychological state, the characteristics of the perception of the world, as well as the strategies and resources of the individual to overcome negative aspects in connection with changes in everyday life.
Study design. The study was built in the format of a socio-psychological survey to study the lifestyle and psychological state of students in self-isolation. Research was conducted in the middle of April 2020.
Participants. 56 people, residents of Russia (8% of men, 92% of women) from 20-23 years old university students of the 2nd (77%) and 5th (23%) courses of psychological specialties (Σav=21.12, Me=21, SD=1.37).
Measurements. The research is based on quantitative and qualitative methodology. We used the method of content analysis for written discourses about the lifestyle in connection with self-isolation and the SAN method, which allows one to draw conclusions about the degree of psycho-emotional state.
Results. Lifestyle changes were recorded by 93% of respondents. The most transformed spheres are activity (educational) and social. The spatio-temporal characteristics of life are of great importance. Assessments of negative and positive changes show parity. Minor manifestations of anxiety and negative emotional states were revealed. The average and medium-high level of psychoemotional state was recorded.
Conclusions. Resources for overcoming difficulties are represented by strategies: 1) “I”: comprehension, self-organization, maintaining physical fitness, self-development; 2) “Others”: help, emotional support for loved ones and strangers; 3) “Living space”: working with the space of the house for arrangement under his “I”, expanding its multifunctionality, maintaining cleanliness.

Authors: Krasilo D.A. , Krasilo T.A. , Zalipaeva A.N.
Published: April 2021

Objectives. Studying the relationship of autonomy and attachment in relationships with parents with real self-determination in students.
Background. The growing world globalization, intercultural contradictions, confrontation within society seriously complicate the path of self-determination of modern youth. At the same time, due to technical progress and digitalization of the communication and education environment, there are significant transformations in the interaction of people in almost all spheres, including in the family. Therefore, the question of studying the most important aspects in the relationship of young people with their parents for real self-determination is especially acute.
Study design. The work studied the indicators of real self-determination, attachment to parents and autonomy among students. The presence of a relationship between these parameters was established by calculating the Spearman correlation coefficient.
Participants. 60 college students aged 18 to 21.
Measurements. Methodology “Scale of adult attachment for close relationships”; autonomy questionnaire (authors O.A. Karabanova and N.N. Poskrebysheva); questionnaire “ORS” (author D.A. Krasilo).
Results. An inverse relationship of indicators of real self-determination of students with the level of intimacy and the level of anxiety (scales of attachment to parents) was established. A direct relationship was revealed between the indicators of real self-determination and the level of autonomy.
Conclusions. Proximity and anxiety (components of attachment) have a significant inverse relationship with the level of real self-determination in students. There are no significant connections between reliability (a component of attachment) and real self-determination in the sample under study. Emotional autonomy, cognitive autonomy, behavioral autonomy, and value autonomy have significant positive correlations with the level of real self-determination in students.

Published: April 2021

Authors present their experience with 36 cases of spinal canal stenosis due to ossification of posterior longitudinal ligament in cervical spine. Ligament ossification extent was found to be local (1 segment) or segmental (2-3 segments). Clinical examination showed cervical myelopathy of various severity. Diagnosis of cervical spinal canal stenosis was determined mainly by CT and MRT. All patients underwent surgical treatment - anterior transcorporal decompression of spinal cord. Positive results were achieved in 34 patients including 22 patients with complete elimination of myelopathy, 9 patients with partial elimination and 3 patients with stopping of the process progression. In 2 patients, surgical procedure was inefficient.
Benign spine tumors in adults
Authors: Burdigin V. N. , Zatsepin S. T.
Published: April 2021

The experience of treatment of 217 patients with primary benign spine tumor (14 nosologic forms) is presented. The importance of axial computer tomography and MRT for diagnosis is outlined. 201 patients have been operated on. In lesion of cervical spine, as rule, the anterior and posterior approaches are used, very seldom combined ones. In operations on thoracic spine the authors prefer the posterolateral extrapleural approach that allows to perform laminectomy, costotransversectomy (sometimes, bilateral) as well as partial or complete spondylectomy. Besides posterolateral approach anterior extraperitoneal one is used for local lesion of lumbar vertebra body. When tumor is localized in the sacrum the posterior approach is used more often, sometimes in combination with uni- or bilateral anterior extraperitoneal ones. Replacement of vertebra body defect is performed by autografts from the upper flaring portion of the ilium, more seldom - by implants. Posterior spondylodesis is carried out using cortical implants with transosseous fixation by metalic wire. In 7 patients, the recurrence has been revealed within 2 years after operation. In the rest of patients there have been no recurrences. The authors make a conclusion that active surgical tactics for primary benign spine tumors is justified and necessary.

The technique of three-point novocaine blockade for shoulder-scapularis periartheritis is described. It is based on the modern concepts of shoulder-scapularis periatheritis pathogenesis which assumes the impingement between greater tubercle of the humerus and anterior segment of acromion in upper expremity abduction (impingement syndrome). The aim of the blockade is the creation of subacromial decompression as a condition for free sliding of rotator cuff in abduction phase. The first point of novocaine injection is subacromial space, the second one biceps sulcus, the third the region of muscle teres minor of scapula. Addition of corticosteroids allows to cure the inflammation of periarticular soft tissues. Novocaine blockade is used in combination with exercise therapy. Complex treatment results are satisfactory. Only 18% of patients with persistent course of shoulder-scapularis periarthritis underwent the operation anterior acromial- plasty by Neer.

Affections of Turbine Nozzle Cross-Sectional Area to the Marine Diesel Engine Working
Authors:   Vietnam Maritime University Hai Phong, Vietnam, Duc Luu Do , Quang Vinh Nguyen
Published: April 2021

After a long period of use, some important technical parameters of the main marine diesel engines (MDE) gradually become worse, such as the turbine speed, intake pressure, exhaust temperature, engine power, and specific fuel oil consumption (SFOC). This paper studies the affections of the turbine nozzle cross-sectional area (AT) to MDE and presents a method of AT adjustment to improve the performances of MDE. A mathematical model of an engine was built based on the existent engine construction and the theory of the diesel engine working cycle and the simulation was programmed by Matlab/Simulink. This simulation model accuracy was evaluated through the comparison of simulation results and experimental data of the MDE. The accuracy testing results were acceptable (within 5%). The influences of AT on the engine working parameters and the finding optimization point were conducted by using the simulation program to study. The predicted optimization point of the nozzle was used to improve the engine’s performances on board. The integration of the simulation and experiment studies showed its effectiveness in the practical application of the marine diesel engine field.

Nautički turizam selektivna je vrsta turizma koja se za gospodarstvo svih ekonomija Europe pokazala izuzetno važnom. Kao i turizam, tako i nautički turizam nije službena gospodarska grana pa ga nećemo naći u Nacionalnoj klasifikaciji djelatnosti (NKD), ali njegove poddjelatnosti možemo barem donekle prepoznati. Promjene NKD-a nastale 2007. donekle su prikrile izvore podvrsta nautičkog turizma, ali spoznaja i linija razvoja za istraživače ostala je prepoznata. Sukladno s time, prilikom procjene važnosti nautičkog turizma, promatrano s aspekta službenih NKD djelatnosti, tu činjenicu treba uzeti u obzir jer se time pridonosi službenoj ocjeni postignutih učinaka. Njegovi su učinci mnogostruki pa se za one neizravne procjenjuje 3 – 5 puta veća vrijednost nego za izravne. U nautičkom turizmu poslovanje marina vezuje za sebe najam plovila te bi se moglo reći da su ove dvije poslovne aktivnosti u simbiozi jer bilježe visok stupanj međuovisnosti. Ipak, profili njihova poslovanja, kao i tržišnog nastupa, bitno su različiti, ali to ne umanjuje njihovu povezanost. Upravo ta činjenica važna je zbog određenih promjena u razvrstavanju nautičkog turizma, što će se u ovom radu samo sporadično naznačiti. Posebna važnost podvrsta nautičkog turizma, posebno u uvjetima ekonomije Hrvatske, ima snažan poduzetnički karakter. Upravo ta činjenica ključna je za ovo istraživanje. Stoga je malo i srednje poduzetništvo, Small & Medium Entrepreneurship (dalje: SME), promatrano s istraživačkog aspekta, zanimljiv karakter marina businessa1 jer se na temelju analize sustava poslovnog djelovanja može raspoznati razina razvijenosti SME-a na makrorazini. Odnosno, da bi se SME razvio, važan je koncept prema kojem se razvija, što se u uvjetima ekonomijâ u tranziciji pokazuje kao ključan problem. Utjecaj države, njezina uloga i način postavljanja sustava po kojem se SME razvija pokazuju bitne razlike u ekonomijama u tranziciji, kao i u razvijenim ekonomijama Europske unije. Stoga će se u ovom istraživanju analizirati hrvatski i njemački sustav, iz čega će se, uz važne spoznaje, moći zaključiti o razlikama u razvijenosti misli o SME-u, što je ključan činitelj razvoja.
Ortognatik Cerrahi Tedavi ve Yumuşak Dokular Üzerindeki Etkisi

Published: April 2021

Büyüme gelişimini tamamlamış hastalarda tek başına ortodontik düzeltimin kapasitesini aşan şiddetli iskeletsel uyumsuzlukların tedavisinde kullanılan ortodontik ve cerrahi prosedürler ortognatik cerrahi olarak adlandırılmaktadır. Bu tedavinin sonucunda kabul edilebilir ve dengeli bir yüz görünümüne, çiğneme ve konuşma fonksiyonlarına kavuşulması ve hastanın esas şikâyetlerinin çözülmesi amaçlanmalıdır. Yüzün yumuşak doku hatları, altta yatan yüz iskeletini yansıtmaktadır, bu nedenle iskeletsel uyumsuzluklar kaçınılmaz olarak yüzün yumuşak dokularını etkilemektedir. Ortodontinin uzmanlık alanı olarak ilk kurulduğu 1900’lu yıllarda, tedaviler ‘Angle’ın sert doku paradigması’na göre, öncelikli olarak okluzyonun ideale getirilmesi şeklinde planlanmaktaydı; ancak son yıllarda, ortodonti ve ortognatik cerrahi tedavide, dentofasiyal problemlerin yüzün yumuşak dokularındaki tedavisine odaklanan ‘yumuşak doku paradigması’ kabul görmeye başlamıştır. Bu yaklaşımda tedavinin sonunda, öncelikli olarak olarak yüz yumuşak dokularının adaptasyonu ve dengesi amaçlanmaktadır. Bu makalede, ortognatik cerrahi tedavinin endikasyonları, hareket kapasitesi ve yumuşak dokular üzerindeki etkilerini ele alan bir literatür derlemesi sunulmuştur.
