Authors: Kim Seondae , Ryu Yeongil , Cho Jinsoo , Ryu Eun-Seok
Published: December 2019

This paper presents two methodologies for delivering multimedia content to visually impaired people with the use of a haptic device and braille display. Based on our previous research, the research using Kinect v2 and haptic device with 2D+ (RGB frame with depth) data has the limitations of slower operational speed while reconstructing object details. Thus, this study focuses on the development of 2D multiarray braille display using an electronic book translator application because of its accuracy and high speed. This approach provides mobility and uses 2D multiarray braille display to represent media content contour more efficiently. In conclusion, this study achieves the representation of considerably massive text content compared to previous 1D braille displays. Besides, it also represents illustrations and figures to braille displays through quantization and binarization.
Development of an Error Model for a Factory-Calibrated Continuous Glucose Monitoring Sensor with 10-Day Lifetime
Authors: Vettoretti Martina , Battocchio Cristina , Sparacino Giovanni , Facchinetti Andrea
Published: December 2019

Factory-calibrated continuous glucose monitoring (FC-CGM) sensors are new devices used in type 1 diabetes (T1D) therapy to measure the glucose concentration almost continuously for 10–14 days without requiring any in vivo calibration. Understanding and modelling CGM errors is important when designing new tools for T1D therapy. Available literature CGM error models are not suitable to describe the FC-CGM sensor error, since their domain of validity is limited to 12-h time windows, i.e., the time between two consecutive in vivo calibrations. The aim of this paper is to develop a model of the error of FC-CGM sensors. The dataset used contains 79 FC-CGM traces collected by the Dexcom G6 sensor. The model is designed to dissect the error into its three main components: effect of plasma-interstitium kinetics, calibration error, and random measurement noise. The main novelties are the model extension to cover the entire sensor lifetime and the use of a new single-step identification procedure. The final error model, which combines a first-order linear dynamic model to describe plasma-interstitium kinetics, a second-order polynomial model to describe calibration error, and an autoregressive model to describe measurement noise, proved to be suitable to describe FC-CGM sensor errors, in particular improving the estimation of the physiological time-delay.
Location of Moving Targets in Substation Non-Line-of-Sight Environment

Published: December 2019

In substations, a localization system based on a wireless sensor network (WSN) is a challenge, because the propagation of the measured signal could be blocked by various devices. In other words, non-line-of-sight (NLOS) propagation, where the signal propagation path is occluded, will affect measurement accuracy. A novel localization method based on a two-step weighted least squares and a probability distribution function is proposed to reduce the influence of NLOS error on the localization result. In this method, the initial multi-group localization result is obtained by the two-step weight weighted least-squares method, and the probability distribution function of the target is constructed by using the initial localization results, which can effectively reduce the influence of the NLOS error on the localization result. The simulation and test results show that the proposed method can keep the coordinate error within 30 cm in the substation. Compared with the localization result of two-step weighted least-squares (TSWLS) method, the average localization error is reduced by more than 1 m. Compared with the other two similar algorithms, the localization accuracy is improved by more than 50%. The tested results show that the localization performance of the method is robustness in the NLOS environment of the substation. While ensuring stability, the proposed algorithm is less efficient than some existing ones. However, under the calculation conditions of ordinary computers, the average single-point calculation time is less than 0.1 s, which can meet the needs of applications in substations.
Stable Tensor Principal Component Pursuit: Error Bounds and Efficient Algorithms
Authors: Fang Wei , Wei Dongxu , Zhang Ran
Published: December 2019

The rapid development of sensor technology gives rise to the emergence of huge amounts of tensor (i.e., multi-dimensional array) data. For various reasons such as sensor failures and communication loss, the tensor data may be corrupted by not only small noises but also gross corruptions. This paper studies the Stable Tensor Principal Component Pursuit (STPCP) which aims to recover a tensor from its corrupted observations. Specifically, we propose a STPCP model based on the recently proposed tubal nuclear norm (TNN) which has shown superior performance in comparison with other tensor nuclear norms. Theoretically, we rigorously prove that under tensor incoherence conditions, the underlying tensor and the sparse corruption tensor can be stably recovered. Algorithmically, we first develop an ADMM algorithm and then accelerate it by designing a new algorithm based on orthogonal tensor factorization. The superiority and efficiency of the proposed algorithms is demonstrated through experiments on both synthetic and real data sets.
Building Sustainable Smart Destinations: An Approach Based on the Development of Spanish Smart Tourism Plans
Authors: González-Reverté Francesc
Published: December 2019

The aim of this research is to assess the real effects of developing smart tourism destinations on urban sustainability. A content analysis method is used to analyze 994 initiatives contained in action-plan and strategy documents from different smart tourism pilot projects funded by Spanish tourism administration. The results indicate that, despite the noteworthy effort to develop smart initiatives, sustainability solutions based on the use of technology are scarcely proposed, suggesting that cultural, managerial and technological barriers do exist. Overall, smart tourism plans are mainly conceived as instruments designed to create new tourism products in a tourism-driven approach. Despite the institutional narrative promoting smart tourism destinations as a guarantee to transform destinations responding to residents’ needs and improve sustainability, pilot projects undergo little interest in holistic sustainable initiatives, suggesting that destination management is focused on a rhetorical approach to sustainability.

Published: December 2019

The efficient management of water resources by the tourism sector is essential to be able to achieve sustainability in the future. Hotels, together with other tour operators, have a responsibility not to use more water than is absolutely necessary. Through a survey carried out in hotels on the island of Mallorca, we asked hotel managers about their water consumption and what types of water-saving measures they had introduced. We identified eleven water-saving measures, which were classified into “advanced” and “simple” according to the technical complications and the level of economic investment required. The numbers of measures of each kind that had been implemented were used as the dependent variables in two different Ordered Probit models. This method allowed us to identify the main variables that explain the introduction of water-saving measures. The significant main variables leading hotel managers to adopt simple water-saving initiatives are the existence of laundry facilities, the age of the hotel, and the number of stars. The same variables were found to be important for the introduction of advanced measures. The main drivers for introducing water-saving measures were the reduction in costs, followed by environmental concerns, while legal requirements and customer loyalty were found to be the least important drivers.

Published: December 2019

Symmetry is a key concept in the study of power systems, not only because the admittance and Jacobian matrices used in power flow analysis are symmetrical, but because some previous studies have shown that in some real-world power grids there are complex symmetries. In order to investigate the topological characteristics of power grids, this paper proposes the use of evolutionary algorithms for community detection using modularity density measures on networks representing supergrids in order to discover densely connected structures. Two evolutionary approaches (generational genetic algorithm, GGA+, and modularity and improved genetic algorithm, MIGA) were applied. The results obtained in two large networks representing supergrids (European grid and North American grid) provide insights on both the structure of the supergrid and the topological differences between different regions. Numerical and graphical results show how these evolutionary approaches clearly outperform to the well-known Louvain modularity method. In particular, the average value of modularity obtained by GGA+ in the European grid was 0.815, while an average of 0.827 was reached in the North American grid. These results outperform those obtained by MIGA and Louvain methods (0.801 and 0.766 in the European grid and 0.813 and 0.798 in the North American grid, respectively).
Strengthening Surveillance Systems for Malaria Elimination by Integrating Molecular and Genomic Data
Authors: Nsanzabana Christian
Published: December 2019

Unprecedented efforts in malaria control over the last 15 years have led to a substantial decrease in both morbidity and mortality in most endemic settings. However, these progresses have stalled over recent years, and resurgence may cause dramatic impact on both morbidity and mortality. Nevertheless, elimination efforts are currently going on with the objective of reducing malaria morbidity and mortality by 90% and malaria elimination in at least 35 countries by 2030. Strengthening surveillance systems is of paramount importance to reach those targets, and the integration of molecular and genomic techniques into routine surveillance could substantially improve the quality and robustness of data. Techniques such as polymerase chain reaction (PCR) and quantitative PCR (qPCR) are increasingly available in malaria endemic countries, whereas others such as sequencing are already available in a few laboratories. However, sequencing, especially next-generation sequencing (NGS), requires sophisticated infrastructure with adequate computing power and highly trained personnel for data analysis that require substantial investment. Different techniques will be required for different applications, and cost-effective planning must ensure the appropriate use of available resources. The development of national and sub-regional reference laboratories could help in minimizing the resources required in terms of equipment and trained staff. Concerted efforts from different stakeholders at national, sub-regional, and global level are needed to develop the required framework to establish and maintain these reference laboratories.
Adapting Urban Light-Rail Transport to the African Context: A Process Conducted by Transport Authorities and Chinese Rail Corporations in Addis-Ababa, Abuja, and Lagos
Authors: Alade Taslim , Edelenbos Jurian , Gianoli Alberto
Published: December 2019

A contextual approach to Light-Rail Transport (LRT) needs to be tailored towards specific contexts, in terms of situations or contingencies, such as socio-economic and environmental factors. This research intends to discuss the societal benefits comprised of well-informed contextual factors for policymakers and urban transport authorities, to enable them to be able to formulate objective policies for a city’s socio-economic development. The aim of this article is to analyze the contextual factors in three cities which are responsible for the contextualization of infrastructural innovations of urban light-rail transport from China. The methodology that has been used is a qualitative method using multiple case studies, which includes a pilot and semi-structured interview. The analysis compares the similarities and differences within Nigeria, and between Nigeria and Ethiopia. The most perceptible contextual factors which influence infrastructural innovations in Nigeria include an electric energy supply, modernization of LRT and their stations, Transit-Oriented Development (TOD), and seamless integration of LRT with other transport modes. The most conspicuous factors in Ethiopia are emergency ticket shops, seamless integration of LRT with other transport modes, and Non-Motorized Transport (NMT). Nigeria and Ethiopia both share the seamless integration of LRT with other transport modes. Therefore, academically analyzing contextual factors helps to unravel the poly-contextualization and context-specific decision-making processes in LRT implementation.
A Comparative Analysis of Factors Influencing Two Outbreaks of Middle Eastern Respiratory Syndrome (MERS) in Saudi Arabia and South Korea
Authors: Willman Marnie , Kobasa Darwyn , Kindrachuk Jason
Published: December 2019

In 2012, an emerging viral infection was identified in Saudi Arabia that subsequently spread to 27 additional countries globally, though cases may have occurred elsewhere. The virus was ultimately named Middle Eastern Respiratory Syndrome Coronavirus (MERS-CoV), and has been endemic in Saudi Arabia since 2012. As of September 2019, 2468 laboratory-confirmed cases with 851 associated deaths have occurred with a case fatality rate of 34.4%, according to the World Health Organization. An imported case of MERS occurred in South Korea in 2015, stimulating a multi-month outbreak. Several distinguishing factors emerge upon epidemiological and sociological analysis of the two outbreaks including public awareness of the MERS outbreak, and transmission and synchronization of governing healthcare bodies. South Korea implemented a stringent healthcare model that protected patients and healthcare workers alike through prevention and high levels of public information. In addition, many details about MERS-CoV virology, transmission, pathological progression, and even the reservoir, remain unknown. This paper aims to delineate the key differences between the two regional outbreaks from both a healthcare and personal perspective including differing hospital practices, information and public knowledge, cultural practices, and reservoirs, among others. Further details about differing emergency outbreak responses, public information, and guidelines put in place to protect hospitals and citizens could improve the outcome of future MERS outbreaks.

The administration of antipyretic analgesics prior to, in conjunction with, or due to sequelae associated with vaccination is a common yet somewhat controversial practice. In the context of human vaccination, it is unclear if even short-term analgesic regimens can significantly alter the resulting immune response, as literature exists to support several scenarios including substantial immune interference. In this report, we used a live attenuated Yersinia pestis vaccine to examine the impact of analgesic administration on the immune response elicited by a single dose of a live bacterial vaccine in mice. Mice were assessed by evaluating natural and provoked behavior, as well as food and water consumption. The resulting immune responses were assessed by determining antibody titers against multiple antigens and assaying cellular responses in stimulated splenocytes collected from vaccinated animals. We observed no substantial benefit to the mice associated with the analgesic administration. Splenocytes from both C57BL/6 and BALB/c vaccinated mice receiving acetaminophen have a significantly reduced interferon-gamma (IFN-γ) recall response. Additionally, there is a significantly lower immunoglobulin (Ig)G2a/IgG1 ratio in vaccinated BALB/c mice treated with either acetaminophen or meloxicam and a significantly lower IgG2c/IgG1 ratio in vaccinated C57BL/6 mice treated with acetaminophen. Taken together, our data indicate that the use of analgesics, while possibly ethically warranted, may hinder the accurate characterization and evaluation of novel vaccine strategies with little to no appreciable benefits to the vaccinated mice.
An Optimization-Based Framework for Nonlinear Model Selection and Identification
Authors: Taghipour Javad , Haddad Khodaparast Hamed , Friswell Michael I. , Jalali Hassan
Published: December 2019

This paper proposes an optimization-based framework to determine the type of nonlinear model present and identify its parameters. The objective in this optimization problem is to identify the parameters of a nonlinear model by minimizing the differences between the experimental and analytical responses at the measured coordinates of the nonlinear structure. The application of the method is demonstrated on a clamped beam subjected to a nonlinear electromagnetic force. In the proposed method, the assumption is that the form of nonlinear force is not known. For this reason, one may assume that any nonlinear force can be described using a Taylor series expansion. In this paper, four different possible nonlinear forms are assumed to model the electromagnetic force. The parameters of these four nonlinear models are identified from experimental data obtained from a series of stepped-sine vibration tests with constant acceleration base excitation. It is found that a nonlinear model consisting of linear damping and linear, quadratic, cubic, and fifth order stiffness provides excellent agreement between the predicted responses and the corresponding measured responses. It is also shown that adding a quadratic nonlinear damping does not lead to a significant improvement in the results.

In quantum theory, the retrodiction problem is not as clear as its classical counterpart because of the uncertainty principle of quantum mechanics. In classical physics, the measurement outcomes of the present state can be used directly for predicting the future events and inferring the past events which is known as retrodiction. However, as a probabilistic theory, quantum-mechanical retrodiction is a nontrivial problem that has been investigated for a long time, of which the Mean King Problem is one of the most extensively studied issues. Here, we present the first experimental test of a variant of the Mean King Problem, which has a more stringent regulation and is termed “Tracking the King.” We demonstrate that Alice, by harnessing the shared entanglement and controlled-not gate, can successfully retrodict the choice of King’s measurement without knowing any measurement outcome. Our results also provide a counterintuitive quantum communication to deliver information hidden in the choice of measurement.

El Mejor Derecho de Propiedad como Petitorio Implícito en las Demandas de Reivindicación
Authors: Vara Bejarano Carlos Virgilio
Published: December 2019

La Corte Suprema de la Republica del Perú, ha establecido como criterio en sus casaciones y un acuerdo plenario, que en las demandas de reivindicación, cuando las partes alegan derecho de propiedad, ya no deben ser declaradas improcedentes bajo el argumento, que previamente deben determinar quien tiene el mejor derecho de propiedad, sino que, allí mismo debe resolverse como punto controvertido. Ahora bien, cuando el mejor derecho de propiedad, es determinado como punto controvertido a efectos de resolver la reivindicación, este se ha sustanciado cual si fuera una pretensión, ejerciendo las partes las garantías que contienen el debido proceso, entre ellos el contradictorio y el derecho a la prueba, para hacer valer su derecho de propiedad y/o cuestionar el del otro, pero como no fue peticionado, no se puede emitir un pronunciamiento sobre el fondo, esto en merito al principio dispositivo por el que sólo las partes pueden incorporar el o los petitorios, debiendo hacerlo de manera clara y concreta , no admitiendo la posibilidad del petitorio implícito y el juez debe pronunciarse únicamente sobre lo peticionado. También la misma corte, estableció como criterio, que emitida la sentencia sobre reivindicación habiéndose determinado el mejor derecho de propiedad como punto controvertido, las partes pueden iniciar otro proceso por mejor derecho de propiedad, pues no hay cosa juzgada material sobre este último extremo. Conforme a lo expuesto, se tendría dos procesos, que por ser independientes podrían llevarse por separado o también acumularse, estando estas dos posibilidades sujetas a la voluntad de las partes, sin embargo de llevarse primero la reivindicación, para luego iniciar otro proceso por mejor derecho de propiedad, pudiendo resolverse ambas en un solo proceso, (sobre todo teniendo en cuenta la estrecha relación que tiene la una con la otra, donde el derecho de propiedad es el presupuesto principal), lo único que genera es dilación y costos innecesarios, tanto para las partes como para el estado mismo. Así expuesto, resultaría conveniente, en aplicación del principio de economía y celeridad procesal, atendiendo a los fines del proceso, que ambas pretensiones sean necesariamente acumuladas y que no se requiera la expresa voluntad de las partes para ello, es necesario entonces incorporar una formula normativa en el Código Procesal Civil, que flexibilice de este modo el principio dispositivo, para que faculte al juez a incorporar como petitorio implico, la declaración de mejor derecho de propiedad, cuando advierta de los fundamentos de hecho que ambas partes tiene derecho de propiedad, para de este modo tramitarlas como reconvención.

Authors: Cañapatana Castillo Wilson , Quipe Flores Deysi Diana
Published: December 2019

El empleo informal se ha convertido en un problema social, pues gran parte de la población no tiene acceso a las condiciones más favorables de trabajo. El empleo informal conlleva a perjuicios para el desarrollo económico y bienestar de la sociedad, pues posibilita la falta de acceso a los beneficios laborales, como acceso a un seguro de salud, gratificaciones y vacaciones. En este trabajo se presenta un modelo logit de probabilidad no lineal, el cual es uno de los modelos más usados para determinar los factores más importantes en variables de respuesta binaria. En tal sentido la finalidad de este trabajo es contribuir con la comunidad local y científica mediante la identificación de los factores que determinan el empleo informal en la región. Los resultados del presente trabajo indican que el ser mujer, pertenecer al sector servicios, comercio, construcción o industria, contar con educación secundaria o superior, ser joven y provenir del área rural son características que determinan la probabilidad de obtener un empleo informal en la región Moquegua.

In this work, numerical results of a nonlinear switching system that presents bistable attractors subjected to stochastic modulation are shown. The system exhibits a dynamical modification of the bistable attractor, giving rise to an intermit behavior, which depends of modulation strength. The resulting attractor converge to an intermittent double-scroll, for low amplitude modulation, and a 9-scroll attractor for a higher applied noise amplitude. A Detrended Fluctuation Analysis (DFA) applied to the x state variable, shows a perturbations robustness region, since the increase of noise does not present changes. Due to the applied noise, the final obtained system has higher randomness, compared with the original one. The understanding of the dynamical behavior of multiscrolls systems is highly important for advancing technology in communications, as well in memory
systems applications.
EEG activity during balance platform test in humans
Authors: Khorev Vladimir , Badarin Artem , Antipov Vladimir , Maksimenko Vladimir , Kurkin Semen
Published: December 2019

In order to analyze different human brain states related to perception and maintaining of body posture, we implemented an experiment with a balance platform. It is known the cerebral cortex regulates subcortical postural centers to maintain upright balance and posture and balance demands. However, the cortical mechanisms that support standing balance remain elusive. In this work, we present an EEG-based analysis during execution of balance responses with distinct postural demands. The results suggest the existence of common features in the EEG structure associated with distinct activity during balance maintaining. This may give new directions for future research in the field of brain activity, and for the development of brain-computer interfaces.
Multidimensional generalization of phyllotaxis
Authors: Lodkin Andrei
Published: December 2019

The regular spiral arrangement of various parts of biological objects (leaves, florets, etc.), known as phyllotaxis, could not find an explanation during several centuries. Some quantitative parameters of the phyllotaxis (the divergence angle being the principal one) show that the organization in question is, in a sense, the same in a large family of living objects, and the values of the divergence angle that are close to the golden number prevail. This was a mystery, and explanations of this phenomenon long remained “lyrical”. Later, similar patterns were discovered in inorganic objects. After a series of computer models, it was only in the XXI century that the rigorous explanation of the appearance of the golden number in a simple mathematical model has been given. The resulting pattern is related to stable fixed points of some operator and depends on a real parameter. The variation of this parameter leads to an interesting bifurcation diagram where the limiting object is the SL(2;Z)-orbit of the golden number on the segment [0,1]. We present a survey of the problem and introduce a multidimensional analog of phyllotaxis patterns. A conjecture about the object that plays the role of the golden number is given.
New results on cycle–slipping in pendulum–like systems
Authors: Smirnova Vera B. , Proskurnikov Anton V. , Utina Natalia V.
Published: December 2019

n this paper, we examine dynamics of multidimensional control systems obtained as feedback interconnections of stable linear blocks and periodic nonlinearities. The simplest of such systems is the model of mathematical pendulum (with viscous friction), so we call such systems pendulum-like. Other examples include, but are not limited to, coupled vibrating units, networks of oscillators, Josephson junction arrays and numerous synchronization circuits used in radio and telecommunication engineering. Typically, a pendulum-like system has infinite sequence of equilibria, and one of the central problems addressed in the theory of such systems is to find the conditions of “global stability”, or gradient-like behavior ensuring that every solution converges to one of the equilibria points. If a system is gradient-like, another problem arises, being the main concern of this paper: can we find the terminal equilibrium, given the initial condition of the system? It is well known that solutions do not converge, in general, to the nearest equilibrium; this phenomenon is known as cycle-slipping. For a pendulum, cycle-slipping corresponds to multiple rotations of the pendulum about its suspension point. In this paper, we estimate the number of slipped cycles for general pendulum-like systems by means of periodic Lyapunov functions and the Kalman-Yakubovich-Popov lemma.
About dynamic stability of deformable elements of vibration systems
Authors: Velmisov Petr A. , Ankilov Andrey V.
Published: December 2019

The dynamics and stability of the elastic elements of vibration devices, modeled by a channel containing elastic elements, are investigated. Inside the channel flows a stream of stirred liquid. The model of the device with two elastic elements is considered. The solution of the aerohydrodynamic part of the problem, based on the methods of the theory of functions of a complex variable, is given. The solution of the original problem is reduced to the study of a coupled system of partial differential equations for the deformations of elements, which makes it possible to study their dynamics. On the basis of the constructed functional for this system, the sufficient conditions of stability are obtained. The conditions impose restrictions on the parameters of the mechanical system. Based on the Galerkin method, the numerical experiments for specific examples of mechanical systems were carried out, confirming the reliability of the investigations. A special case of the model of device with one elastic element is considered. Based on this case, a comparison with the model of the vibration device considered earlier is made.

The model of a vacuum diode under the influence of a strong external magnetic field is considered. The uninsulated variant, when a part of electrons emitted from the cathode reaches the anode, is investigated. The model is described by a singular boundary value problem for a system of ordinary differential equations. The sensitivity of the problem solution to the change of input parameters is investigated. A coordinate descent method to restore parameters of the boundary value problem is implemented numerically.
HEMATOKRIT DAN KADAR HEMOGLOBIN DENGAN KONSUMSI OKSIGEN MAKSIMAL (VO2MAKS) PADA ATLET REMAJA

Published: December 2019

Latar Belakang: Kapasitas fisiologi dan latihan yang menggunakan aktivitas aerobik yang tinggi pada akhirnya akan menunjukkan konsumsi oksigen secara maksimum (VO2 maks) yang merupakan indikator untuk menentukan kebugaran atlet dalam upaya mencapai kesuksesan.1 Kebugaran dipengaruhi oleh beberapa faktor yaitu latihan yang intensif dan teratur, faktor genetik, dan asupan gizi yang cukup.2 Badan Tim Nasional PSSI mengemukakan bahwa atlet sepak bola profesional Indonesia sering mengalami penurunan daya tahan pada babak kedua khususnya mulai menit ke-60. Dokter Tim Nasional Indonesia juga menyatakan bahwa untuk keseluruhan tim U-16 dan U-19, ditemukan rata-rata nilai hemogoblin kurang lebih 80 % berada di bawah standar atlet. VO2 maks dipengaruhi indikator hematologi seperti hemoglobin (Hb) dan hematokrit (Hct), yang berperan dalam mentransfer oksigen pada jaringan yang aktif. Fungsi hemoglobin dalam tubuh tergantung kemampuannya bergabung dengan oksigen dalam paru-paru, kemudian melepas oksigen dalam jaringan kapiler. Hematokrit adalah porsi dari total volume darah yang dibentuk oleh sel darah merah.3 Oleh karena itu perubahan indikator biokimia Hb dan Hct ini berpengaruh pada performa fisik atlet.Tujuan: Tujuan umum dari penelitian ini adalah untuk menganalisis hubungan hematokrit (Hct) dan kadar Hemoglobin (Hb)  dengan konsumsi oksigen maksimum (VO2 maks) pada atlet remaja.Metode Penelitian: Desain penelitian cross-sectional dengan sampel dipilih secara simple random sampling. Data Kadar hemoglobin dan hematokrit diperoleh dengan menggunakan alat pengukur digital (pengambilan darah melalui pembuluh perifer), sedangkan konsumsi oksigen maksimum (VO2 maks) dengan pengukuran metode Multi Stage Fitness Test. Analisa bivariat dengan uji non parametrik Spearman Correlation dengan tingkat kepercayaan 95% dan Cochran's Mantel-Haenszel.Hasil: Tidak ada hubungan bermakna hematokrit (Hct) dengan konsumsi oksigen maksimum (VO2 maks) pada atlet remaja p= 0,485,  r = 0,080 (p>0,05). Ada hubungan bermakna kadar Hemoglobin (Hb) dengan konsumsi oksigen maksimum (VO2 maks) pada atlet remaja p= 0,002, r =0,323 (p<0,05). Ada pengaruh jenis kelamin terhadap hubungan Hmt dengan tingkatan vo2maks p= 0,036 (p<0,05). Ada pengaruh jenis kelamin terhadap hubungan hemoglobin dengan tingkatan  VO2maks p= 0,004 (p<0,05). Tidak ada pengaruh jenis cabang olahraga terhadap hubungan Hmt dengan VO2maks p=0,613(p>0,05).
