UNSTRUCTURED After carrying out a bibliographic review of the different ways of estimating the load during suspension training, this study describes the theoretical foundations of the development of a mobile phone application (Kinematic lab susp) that allows estimating the load mobilized when training with devices in suspension (type TRX ®). Methods: systems of equations are proposed whose terms depend on the angulation of the device with respect to the vertical (angle α), the relationship between the height of grip and the height of the center of mass, and the weight of the subject that are recorded by means of a photograph. Results: after taking a photograph and incorporating the height of the subject, the application allows measuring the angle α, providing values of applied force (in N) and mobilized load in relation to the percentage of body mass applying the calculations described in our equations. The study also provides the estimated value of the load mobilized during a push on the floor (68% of the subject's body mass) and the equation for the calculation of the mobilized load when the suspension device is fixed to the feet. Conclusions: it is possible to estimate by means of equations the load mobilized in each repetition during the training by suspenesion devices. Kinemtaic lab susp is the first mobile app that allows this calculation to be made from the taking of a photograph.

Introduction: This study describes the theoretical foundations of the development of an equation that allows for the estimation of the mobilized load when training with suspension devices (type TRX®) and presents a mobile application as a means for its use. Methods: Systems of equations are proposed of which the terms depend on the angulation of the device with respect to the vertical (angle α), the relationship between the height of grip, the height of the center of mass and the weight of the subject, which are recorded from a photo. Results: Based on the photo and the subject’s standing height, the application allows the user to measure the angle α, providing the values of applied force (in N) and mobilized load in relation to the percentage of body mass, applying the calculations described in our equations. The equation also provides the estimated value of the load mobilized during a push up on the floor (68% of the subject’s body mass) and the equation for the calculation of the mobilized load when the suspension device is fixed to the feet. Conclusions: It is possible to use equations to estimate the load mobilized in each repetition during training using suspension devices and to implement this algorithm in a mobile application.

BACKGROUND Although millions of overweight and obese adults use mobile phone apps for weight loss, little is known about the predictors of success. OBJECTIVE The objective of this study was to understand the relationship between weight loss outcomes and weekly patterns of caloric intake among overweight and obese adults using a mobile phone app for weight loss. METHODS We examined the relationship between weekly patterns of caloric intake and weight loss outcomes among adults who began using a weight loss app in January 2016 and continued consistent use for at least 5 months (N=7007). Unadjusted and adjusted linear regression analyses were used to evaluate the predictors of percentage of bodyweight lost for women and men separately, including age, body mass index category, weight loss plan, and difference in daily calories consumed on weekend days (Saturday and Sunday) versus Monday. RESULTS In adjusted linear regression, percentage of bodyweight lost was significantly associated with age (for women), body mass index (for men), weight loss plan, and differences in daily caloric intake on Mondays versus weekend days. Compared with women consuming at least 500 calories more on weekend days than on Mondays, those who consumed 50 to 250 calories more on weekend days or those with balanced consumption (±50 calories) lost 1.64% more and 1.82% more bodyweight, respectively. Women consuming 250 to 500 calories or more than 500 calories more on Mondays than on weekend days lost 1.35% more and 3.58% more bodyweight, respectively. Compared with men consuming at least 500 calories more on weekend days than on Mondays, those consuming 250 to 500 calories or more than 500 calories more on Mondays than on weekend days lost 2.27% and 3.42% less bodyweight, respectively. CONCLUSIONS Consistent caloric intake on weekend days and Mondays or consuming slightly fewer calories per day on Mondays versus weekend days was associated with more successful weight loss.

Objectives Early diagnosis of biliary atresia is essential to improve long-term outcomes. Newborn screening with an infant stool color card allows early recognition of biliary atresia patients. Our aim was to develop and validate a mobile phone application (PopòApp) able to identify acholic stools. Methods An intuitive app was developed for iOS and Android smartphones. A learning machine process was used to generate an algorithm for stools color recognition based on the seven colors of the infant stool color card, which were considered as the gold standard. Consecutive images of stools were taken by the PopòApp, directly into the diapers of children aged ≤6 months. The PopòApp classified the photographs as “normal”, “acholic” or “uncertain”. To validate the PopòApp, four doctors independently classified all images, and only those for which all doctors agreed were included. The sensitivity, specificity, positive/negative predictive values, and accuracy of the PopòApp were evaluated. Results Of 165 images collected, 160 were included in the study. All acholic stools were recognized by the PopòApp. The PopòApp sensitivity was 100% (95% CI:93.9%–100%) with no false negatives, regardless of the brand of phone. The specificity was 99.0% (95% CI:94.6%–99.9%). The accurancy of the PopòApp was 99.4% (95% CI:96.6%–99.9%), with a positive predictive value of 98.4% (95% CI:89.8%–99.8%). Conclusion The current study proved, in a large cohort, that the PopòApp is an accurate and easy tool for recognition of acholic stools. The mobile App may represent an effective strategy for the early referral of children with acholic stools, and potentially could improve the outcomes of biliary atresia.

AbstractSchmorl’s nodes are vertical herniation of intervertebral discs into the body of neighbouring vertebral endplate. Notwithstanding extensive studies, no consensus has been reached in the subject of their possible etiology. It is hypothesized that physical stress, trauma and high axial loading are the key factors in the occurrence of this pathology. The main objective of the current work is to reevaluate the relationship between stature and body mass and Schmorl’s nodes. For this purpose, skeletal samples from Lithuania (44 males and 19 females) and Poland (97 males and 60 females) were used. The study confirmed that Schmorl’s nodes are age-independent, and more frequent in males (12.63% on the superior and 19.32% on the inferior surface of vertebrae) than in females (6.23% and 12.29% respectively). Obtained results also suggest that high stature (e.g. Spearmann correlation for superior:R=0.20 p=0.017, and inferior:R=0.31p=0.000 surface of vertebrae) and body mass (R=0.25,p=0.002 andR=0.32,p<0.001, respectively) are factors that increase the risk of Schmorl’s nodes. Authors hypothesize that the afore-mentioned body size traits alter loadings acting on intervertebral discs, and rigidity of the spine.

Based on a literature review on the theoretical foundations of information marketing and user studies were selected two master dissertations of a Postgraduate Program in Information Science that addressed user studies as a methodological procedure to understand the relationship between supply and demand. The objective of reporting the results of the two master dissertations was to highlight the alternative approach for these studies focusing on users’ perception as a methodological procedure to study the management of information supply and demand in a digital library and a management information system in an information marketing perspective. Despite the different objectives of the dissertations selected, it is inferred that alternative approach of users studies as a methodological procedure to study the users' perception about information supply and demand is possible. This theoretical and methodological approach to integrate the concepts and principles of information marketing in user studies in the context of management of information supply and demand is significant as a contribution to the knowledge on the subject studied.

The subject of the study is the methodological principles of the study of the budget financing system in the conditions of economic transformation. The purpose of the article is to form a methodological toolkit of the budget financing system, which includes principles, forms, approaches to the analysis of this concept. The following methods are used in the article: analysis and synthesis, generalization – in the study of literature sources on the research topic; abstractions, inductions, deductions, ascent from the abstract to the concrete – in the disclosure of the methodological bases of budget financing systems taking into account the laws of dialectics, application of systemic and functional approaches. In the course of research the forms of budgetary financing and their features are defined, the structural-logical scheme of methodological maintenance of system of budgetary financing is constructed. The article reveals the methodological essence of the formation of budget expenditures as the basis of the budget financing system, which consists in applying tools to the formation of budget expenditures on the principles of scientificity, validity, transparency, economy, traceability. It is determined that the problems significantly affect and adjust the state of the budget system, so when forming budget expenditures it is necessary to take into account these problems and implement measures to maximize their leveling with further adjustment of expenditures. The relationship between the philosophical categories of the spheres of life and the sphere of the essence of budget expenditures in the process of formulating the theoretical foundations of budget financing is clearly traced. The study allowed to form a new methodological tradition in modern financial theory, which consists in the formation of not only practical but also philosophical approaches, abandonment of the search for a single concept of budget financing and unambiguous methods of its construction, the use of advanced methods of economic research etc.

The article considers the peculiarities of establishing jurisdiction in inheritance cases with a foreign element. Attention is paid to the formulation of the theoretical foundations of the institution of inheritance with a foreign element, the classification is carried out, the conceptual apparatus, the sources of international inheritance law are formulated. The analysis of the domestic legislation of Ukraine, regulates the issue of determining the jurisdiction of cases with a foreign element. In particular, attention is paid to the priority of using international legislation on domestic in jurisdictional matters. The norms of multilateral international agreements approved by the Verkhovna Rada of Ukraine, as well as bilateral international agreements on legal assistance concluded between Ukraine and other states, which establish the rules of jurisdiction of inheritance cases with a foreign element, are considered. Processes of social internationalization, which are an integral part of modern life, the expansion of various contacts of Ukrainian citizens with foreigners, as well as active migration processes, the possibility of acquiring property abroad, a significant increase in marriages with foreigners, intercountry adoption cause a sharp increase in inheritance with a foreign element, which are the subject of litigation. The foreign element in the inheritance relationship may be manifested in such a way that the testator and heirs are citizens of different states or reside in different countries. Property that is part of the inheritance may be located in different countries. In this context, there is reason to conclude that the relationship subject to legal regulation has a legal relationship with the legal systems of two or more countries. In different jurisdictions, the substantive regulation of inheritance has its own characteristics. It is concluded that the determination of the admissibility of the statement of claim in relation to the disputed inheritance relationship with a foreign element is impossible without the use of a special procedure defined in the study.

Panel attrition poses major threats to the survey quality of panel studies. Many features have been introduced to keep panel attrition as low as possible. Based on a random sample of refugees, a highly mobile population, we investigate whether using a mobile phone application improves address quality and response behavior. Various features, including geo-tracking, collecting email addresses and adress changes, are tested. Additionally, we investigate respondent and interviewer effects on the consent to download the app and sharing GPS geo-positions. Our findings show that neither geo-tracking nor the provision of email addresses nor the collection of address changes through the app improves address quality substantially. We further show that interviewers play an important role in convincing the respondents to install and use the app, whereas respondent characteristics are largely insignificant. Our findings provide new insights into the usability of mobile phone applications and help determine whether they are a worthwhile tool to decrease panel attrition.
