Authors: Angelovič Michal , Jablonický Juraj , Tkáč Zdenko , Angelovič Marek
Published: December 2020

Goal of this study was to investigate and evaluate an impact of two alternative fuels on smoke emissions in comparison to diesel fuel. This study observes three different combustion engine fuels: biodiesel produced by Meroco, Inc. Company (Alternative fuel I); biodiesel produced in factory situated in Sereď (Alternative fuel II); and conventional diesel fuel (Diesel fuel) from Slovnaft, Inc. Company service station. All measurements were repeated three times. Measurements were conducted by free acceleration test at different engine loads. A statistically significant difference (P <0.05) in smoke emissions values was detected between Alternative fuel I and conventional Diesel fuel, and between Alternative fuel I and Alternative fuel II. The difference in smoke emissions values between conventional fuel and Alternative fuel II was not statistically significant (P >0.05). Tested engine has met the requirements of the EURO 3 emission limit values in relation to the measurement results of particulate matter emissions.

Authors: Ben Amar Fathi , Ben Maachia Sihem , Ayadi Mohamed
Published: December 2020

A total of seventeen olive ecotypes were identified in the oasis region of Degache (Tozeur, Tunisia). The following physicochemical parameters of their oils were studied: acidity, refraction index, polyphenol, chlorophyll and carotene contents, oleic, palmitic and linoleic acid levels and the UV absorbance (K232 and K270). The acidity, K232 and K270 parameter values were used to classify most of the olive oils considered as ‘extra virgin’. The highest carotene, chlorophyll and polyphenol contents of the olive oils examined were found to be 13.60 ppm, 9.10 ppm and 796 ppm, respectively. The oleic acid level of the olive oils considered ranged between 47% and 73%, whereas the palimtic acid level ranged between 11.8% and 23%, and the linoleic acid level ranged between 8.8% and 22.5%. Therefore, the fatty acid composition of the most olive oils considered was in keeping with the IOC norms. The Pearson correlation coefficients obtained were found to be negatively significant for the oleic, palmitic and linoleic acid levels recorded. The cluster and principal component analyses performed revealed the importance of fatty acids and polyphenol contents in the clustering of olive ecotypes. The selection of olive ecotypes according to oil quality is possible, requiring further studies focusing especially on their agronomic characters.

Published: December 2020

Retama sphaerocarpa shrubs form populations that can be an important forage resource during the dry season when pasture shortages are common in certain arid and semi-arid Mediterranean basin regions. The leaves of R. sphaerocarpa were analyzed for dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and acid detergent lignin (ADL) contents. Leaves were also analyzed for the concentration of macro- (P, K, Ca and Mg) and microelements (Mn, Zn, Fe, and Na). According to the contents of CP, NDF, ADF and ADL in the leaves examined, this species could strike an appropriate balance between available feed ingredients for daily nutritional needs of animals. The contents of Ca, K, Na, P, Fe, Mg, and Zn in Retama sphaerocarpa shrubs were found to be high, compared to a number of other forage shrub species. Conversely, the rate of natural regeneration of this shrub in situ was estimated at 2-5%. R. sphaerocarpa seeds are affected by seed coat dormancy that prevents seed germination under natural conditions. The seed germination was assessed at a laboratory after the chemical scarification of seeds by concentrated sulphuric acid in the duration range of 0 min and 240 min. The principal component analysis of data related to the germination ability and seedling emergence showed that the best pretreatment was 120 min immersion in sulphuric acid at 25°C (± 2°C), resulting in 86% of the final germination percentage (FGP) and 14.6 cm of the seedling length (SL). According to the results obtained, this species could be considered a ruminant feed of great nutritive value when drought decreases grazing herbaceous biomass yields. These results should encourage farmers and foresters to integrate R. sphaerocarpa into their planting programs.

Published: December 2020

The study assessed coping strategies adopted during economic recession by male and female members of rural households in Osun State, Nigeria. The study specifically examined the perceived causes of economic recession, investigated the perceived effects and identified the coping strategies adopted by the male and female members of the rural households during economic recession and their level of adoption. A multistage procedure was used to select 120 respondents from 6 local Government Areas of the State. An interview schedule was used to collect data from the respondents. The collected data were analysed using appropriate descriptive and inferential statistics such as frequency counts, percentages, means and independent T-test analysis. The mean ages of the male and female respondents were 45.2 ± 14.1 years and 37 ± 12.6 years respectively. The majority of the males (78.3%) and females (80%) were married with the mean household size of 7 ± 3 people for the male and 6 ± 2 for the female respondents. The cause of economic recession mostly perceived by the male and female respondents was poor economic planning (mean=3.87, 3.77), while prioritizing spending (mean=2.80, 2.52) was the most adopted strategy by both males and females. No significant difference was found in the effects of economic recession on the male and female respondents (t = -0.19; p >0.05) and likewise no significant difference was found in their economic recession coping strategies (t=0.115; p ≥ 0.05). The study concluded that there was no significant difference in the economic recession coping strategies between the male and female members of rural households in the study area.
A Study into the Relationship between Restaurant Tipping and Food Service Tangibility in Kisumu County, Kenya
Authors: Were Simon O. , Miricho Moses N. , Maranga Vincent N.
Published: December 2020

Tipping is believed to have vast influence on restaurant food service tangibility, and thus, quality. This forms the basis of the assumption that foodservice clients are in a better position to reward and monitor the quality of restaurant food services. Nonetheless, the act of tipping has seriously been abused by food servers, hence compromising food service tangibles and thus quality. As a consequence, this is the origin of the observed service failures, not only within restaurant food service but also in the entire service industry. Therefore, the study sought to investigate the relationship between tipping and tangibility of restaurant foodservice. Cross tabulation, correlation as well as multiple regression was used in the analysis of data. The study found a weak significant association between tipping and food service tangibility (Pearson's R = 0.150, P-value > 0.05). However, multiple regression results indicate that restaurant tipping does not statistically significantly predicts the dependent variable – tangibility of food service (F = 45.619). Thus, at 95% confidence level, the study therefore concluded that there is no statistically significant relationship between restaurant tipping and tangibility of food service within the sampled hotels in Kisumu County, Kenya.
Influence of Heat Generation/Absorption on Mixed Convection Flow Behaviour in the Presence of Lorentz Forces in a Vertical Micro Circular Duct Having Time Periodic Boundary Conditions: Steady Periodic Regime
Authors: Aina B. , Isa S.
Published: December 2020

The problem of mixed convection flow of a heat generating/absorbing fluid in the presence existence of Lorentz forces in a vertical micro circular subjected to a periodic sinusoidal temperature change at the surface has been studied taking the first-order slip and jump effects into consideration. The research analysis is carried out by considering a fully developed parallel flow and steady periodic regime. The governing equations, together with the constraint equations which arise from the definition of mean velocity and temperature, are written in a dimensionless form and mapped into equations in the complex domain. One obtains two independent boundary value problems, which provide the mean value and the oscillating term of the velocity and temperature distributions. These boundary value problems are solved analytically. A parametric study of some of the physical parameters involved in the problem is conducted. The results of this research revealed that the magnetic field has a damping impact on the flow and results in decreases in fluid velocity for both air and water. Furthermore, the presence of the heat generation parameter is seen to enhance the temperature distribution and this is reflected as an increase in the magnitude of the oscillation dimensionless velocity, whereas in the presence of heat absorption a reversed trend occurs.

This study will allow the detection and localization of vibration phenomena in the studied gas turbine based on the input / output data.
Mixed Convective Flow of Unsteady Hydromagnetic Couple Stress Fluid Through a Vertical Channel Filled with Porous Medium
Authors: Makhalemele C.R. , Rundora L. , Adesanya S.O.
Published: December 2020

In this paper, the mixed convective flow of an electrically conducting, viscous incompressible couple stress fluid through a vertical channel filled with a saturated porous medium has been investigated. The fluid is assumed to be driven by both buoyancy force and oscillatory pressure gradient parallel to the channel plates. A uniform magnetic field of strength B0 is imposed transverse to the channel boundaries. The temperature of the right channel plate is assumed to vary periodically, and the temperature difference between the plates is high enough to induce radiative heat transfer. Under these assumptions, the equations governing the two-dimensional couple stress fluid flow are formulated and exact solutions of the velocity and the temperature fields are obtained. The effects of radiation, Hall current, porous medium permeability and other various flow parameters on the flow and heat transfer are presented graphically and discussed extensively.

Published: December 2020

The paper presents the results of experimental investigations and numerical analyses performed on reinforced concrete flat slabs. Two tests were carried out on two flat slab specimens designed without specific shear reinforcement. The present paper deals only with the experimental behaviour and numerical modelling of such slabs, this representing the initial part of a larger study which aims to evaluate the shear capacity of such deficient slabs resulted from faulty design or execution and to identify viable and efficient strengthening solutions. ATENA finite element software package was used to numerically model the behaviour of the specimens. A very good agreement was achieved between the results of experimental investigations and numerical modelling with deviations of 0.2% in terms of maximum load carrying capacity and of 7% in terms of corresponding displacement. The specimens were able to carry loads of more than 950kN, larger than those evaluated using designated Eurocodes, displaying a safety factor of 2.72.
Experimental Determination of the Discharge Coeffcient Through Circular Orifice in PVC Pipes
Authors: Hotupan Anca , Hadarean Adriana
Published: December 2020

Real water losses derived from water supply systems represent an important topic, nowadays. It is difficult to predict and to calculate the water lost volume, these values being crucial in any water balance. In addition, the leakage flow can be estimated only when the geometric and hydraulic characteristics of the pipes and the period of time associated to the leakage are known. Also, by using the equation of the water flow can be obtained inaccurate values, especially when incorrect values of discharge coefficient are used. The values of the discharge coefficient can vary between 0.6 and 0.85, depending on a multiple aspects, such as the pipe diameter, the orifice size and shape, the pipe material, the orifice position on the pipe wall, the pipe thickness and the hydraulic parameters of the water (flow and pressure). This paper is focused of an experimental study of a leak simulation in a PVC pipe. Thereby, a circular orifice is drilled on PVC pipe wall and the influence of the water flow and pressure on the discharge coefficient (Cd) is analysed. The experimental values obtained for de Cd are 0.59 - 0.86, values that are in accordance with the results from similar studies.

Authors: Jaafarian M. , Ardeshir A. , Boyaghchi A. Firozi
Published: December 2020

Private section investment in the construction of transportation infrastructure, one of the most important of which is freeway projects, has been extensively used in developing countries in recent decades. However, in many cases due to the lack of necessary investigations and studies, the criteria have not been properly identified and, as a result, the proper way of participating in large-scale transport projects has resulted in numerous problems and, in some cases, project failure. However, choosing a private-public partnership will have a major impact on the success of freeway construction. However, due to the current conditions of the country’s economy, these projects are following with some risks. Therefore, in this study, the financial risk assessment of “public-private partnership” financing for road construction projects in Iran was investigated using the uncertainty approach and the BAS method. The research population of this study consisted of 23 researchers and experts with Ph.D. degree in finance with minimum degree of associate degree and experience of research and financial consulting in investment firms. According to the results, the lack of stability in planning and implementation of government programs and political risks, increases the risk of road construction projects and, in this regard, controlling the price fluctuations and bank financing of road construction projects can reduce the risk of these projects.

Authors: Madani Seyyedeh Ellieh Moafi , Hassani H. , Tokhmechi B.
Published: December 2020

The fracture network in hydrocarbon reservoirs plays a major role in reservoir fluid transfer to production wells. Modeling of fracture in fractured reservoir is often done randomly. Modelling is based on image logs and core information. Because the information is available in a small number of wells, the model is not reliable and this problem makes it impossible to predict the correct flow rate and the amount of wells produced. In this study, an algorithm based on primary and secondary data for fracture network modelling in one of the southwest fields of Iran has been presented. The initial data include aperture fracture and fracture density, and secondary data includes petrophysical data, i.e. electrical resistance and resistance logs used to scale-up characteristics of fracture in wells. In this study, we tried to increase the accuracy of modelling by using modelling conditionality on existing and constructed data. Gaussian conditional simulation produces a set of realizations on which non-linear statistics can be readily available. In this way, information was entered into the model in areas where fracture was predicted to exist. Using the turning bands co-simulation method in geostatistic, the fracture characteristics were simulated in wells that were not available. Using the results of the 3D model, the fracture of the reservoir was re-constructed. The results showed that the modelling performed in this study has been able to increase the fracture prediction accuracy and their properties in fracture density by about 9% and in the fracture opening by about 5%.

Authors: Shirkhanghah B. , Kalehsar H. Eimani
Published: December 2020

The purpose of this study is to assess the effects of cross-section and slenderness on the dynamic response of high-rise buildings constructed on the coarse soil. In this work, the simulation of the wind and soil effects on the high-rise buildings are done numerically using the ABAQUS software. The wind-induced vibration of the building models is studied through Computational Fluid Dynamics (CFD) and Computational Structural Dynamics (CSD). Co-simulation is accepted for the transfer of loads from the fluid to the structural domain. The mechanical response of the soil system is modeled using direct method. Suitable contact elements for slippage and separation modeling between subsurface elements are also considered. Finally, fluid and structural responses are compared in terms of mean and root mean square values with laboratory results on the wide range of reduced velocities. It is concluded that height and cross-section of building affect the vibrational response of the building, and therefore the designer must carefully consider these factors in order to ensure that the design is safe.
Theoretical and Practical Assessments of Transfer Prices. Legal Evidence from Romanian Case Law
Authors: Dumiter Florin Cornel , Jimon Ștefania Amalia
Published: December 2020

Transfer pricing represents the mainstream agenda in the light of tax law, lato sensu, and international taxation, stricto sensu. At the international level, there can be an emphasis on several problems related to taxation: double taxation, double non – taxation, permanent establishment, business profits, residence criteria, arm's length principle, mutual agreement procedure, dispute resolution of tax conflicts. However, the problem of transfer pricing has more profound judicial and economic implications. The main objective of this paper is to evaluate and assess the underlying features and characteristics of transfer prices in the economical and judicial actual context. The operational objectives are related to a quid pro quo analysis regarding the fine-tuning aspects of transfer pricing in the digital taxation era. The case law presented in this article tackles the main problems of applying transfer pricing international regulation upon Romanian tax jurisprudence. The conclusion of this article highlights the need, mutadis mutandis, for a tax policy agenda revealing a strengthened fiscal and financial environment towards the creation of a new proper fiscal space.

Relevant Issues of Exploration the Concept of Indigenous People in the International Legal Instruments and Ukrainian Legal Doctrine
Authors: Melnykova Dariia
Published: December 2020

In this paper, the problem of determination of the legal personality of indigenous people as a subject of international law is considered. Hence, the problem articulated above leads to the issue related to aspects of practical realization and protection of rights and freedoms of indigenous people enshrined in international legal instruments, which is revealed. The confusion of the term “indigenous people” with that of “national minorities” can be avoided by the subjects of international law. However, one cannot find a solution to this problem without envisaging written rules on the concept of ingenious people in one obligatory, for contracting parties, an international legal instrument. Thereafter, the concept of indigenous people must be unified and, consequently, used by all international legal community. The relevance of this study is due to the need to determine the legal status of indigenous peoples in Ukrainian law. Ukraine has recently acceded to the UN Declaration on the Rights of Indigenous Peoples, which defines the need to implement these provisions in national legislation and ensure the practical implementation of the rights and freedoms enshrined for indigenous peoples. To date, the Constitution of Ukraine makes a distinction between the categories of national minorities and indigenous peoples, but there is no specialized comprehensive law that would determine the legal status of indigenous peoples in Ukraine, in the presence of such a law on national minorities. Thus there is a need to determine the concept of indigenous peoples in Ukrainian legislation.
Juvenile Justice: Genesis and Current State in Ukraine
Authors: Kyrylenko Mariia
Published: December 2020

In this paper, the problem of the functioning of the juvenile justice as a system of all parts of the state mechanism, that deal with the problems of protection and socializing of children is considered. It is determined that the protection of children's rights in Ukraine is an urgent question. That is why providing proper conditions for life, development and socialization of the younger generation has become one of the priorities for the state policy of Ukraine. Hence, juvenile justice is one of the most effective ways to protect the rights and interests of children and youth. However the tendencies of formation of the juvenile legal policy of the state influence whether legal regulation of children’s protection can be implemented in the legal system of the state to that extent that it promotes the development of children's protection. Thus, there is a necessity to analyze the genesis, development and the current state of the juvenile law in Ukraine taking into account the practice of foreign states and defining the further perspectives of the juvenile law.
Penal Orders and the Role of Prosecutors in Switzerland
Authors: Enescu Raluca
Published: December 2020

Minor infractions represent the majority of criminal cases. Simplified or summary procedures have addressed their increasing number in order to unburden the courts. Because of reduced requirements for the case to be adjudicated, this procedural economy comes usually to the cost of the defendant. Penal orders represent the most successful form of fast track procedure in which the public prosecutor plays a predominant role. After a police report and sometimes a short investigation, penal orders are issued and notified to the defendant. If they are not objected, their judgment equals the decision of a court. In other words, penal orders rely on the tacit agreement of the defendant. This contribution presents the risks of penal orders to produce wrongful convictions and proposes a set of recommendations that could improve the current situation. A combination of legal sources and empirical studies shed light on the delicate balance between the efficiency of justice and the defendant’s rights.
Tax Enforcement Procedure Under Section 104 of Personal Income Tax Act: Matters Arisings
Authors: John Kachi Bielu
Published: December 2020

The refusal of a taxpayer to respond or pay the tax due has always provoked the tax authority to approach the court with an ex-parte application in chambers. The result of this ex parte application arms the tax authority with a restraining order. With a detached team of policemen, the tax authority will storm the premises of the taxpayer, vandalize, forcefully drive out the tax payer and seal up the premises. All these arrangements and decisions are done behind the taxpayer. This paper examined the constitutionality of the entire procedure for the recovery of tax due to the tax payer. The paper utilized doctrinal methodology in analyzing the extant laws and case laws as they relate to the subject matter. The paper submits that decisions under section 104 PITA are too weighty to be taken in the absence of the taxpayer. The paper, therefore, recommends some sort of judicial activism by judicial officers in exercising their discretion and accommodate the interest of the taxpayer.
Quo Vadis, Business? The migration of companies between cities using the example of the Mazowieckie voivodship in Poland
Authors: Cybulska Magdalena , Dziemianowicz Wojciech
Published: December 2020

Relations between metropolitan core cities and regional and sub-regional centres are part of a broader discussion on the importance of metropolitan areas for the development of regions. These relations are dealt with in this paper in the context of the growth pole theory. The paper focuses on the migration process in relation to enterprises. By moving their businesses, companies contribute to backwash and spread effects. Since company migrations between municipalities occur in both directions, the question remains open as to which migration direction dominates – whether from sub-regional centres to core cities or vice versa. This paper attempts to verify the hypothesis that regional and sub-regional centres in the Mazowieckie voivodship suffer the largest loss of enterprises due to migration to the core city of Warsaw. The results obtained were varied and the hypothesis was confirmed, especially in the case of three cities: Siedlce, Radom and Płock; and partly in the case of Ciechanów.
The Contributions of the Council of Trent to the Catholic Reformation
Authors: Fastiggi Robert
Published: December 2020

This article begins by examining what is meant by the Catholic Reformation and how it relates to the other frequently used term, Counter–Reformation. It then discusses the different ways Catholics and Protestants in the early 16th century understood ecclesial reform. Next there is a consideration of the call for a general or ecumenical council to resolve the differences between the Catholics and Protestant reformers; the reasons for the delay of the council; and the reasons why the Protestants did not participate. The article then provides a summary of the three main periods of the Council of Trent: 1545–1547; 1551–1552; and 1562–1563 along with the 1547–1549 Bologna period. This is followed by a detailed overview of the reforms of the council, which were both doctrinal and disciplinary. The article shows that, while abuses related to various Catholic practices and the sacraments were addressed, the main concerns in the various disciplinary decrees related to clerical corruption and immorality. The article addresses the need for bishops to reside in their dioceses; stop clerical corruption, greed, and nepotism; and establish seminaries for the proper formation of priests. After the review of the disciplinary reform decrees, attention is given to the Catechism of the Council of Trent that served as a resource for parish priests in their instruction of the faithful. The final section considers viewpoints of different historians regarding the effect of the Council of Trent on reform within the Catholic Church.
Vérité mondaine et vérité phénoménologique
Authors: de Moura Carlos Alberto Ribeiro
Published: December 2020

Husserlian phenomenology has been interpreted as a method of knowledge that can be applied to different domains and which would compete with other methods to give us a better understanding of the “real”, the “man” or “society”. Moreover, “phenomenological idealism” has been presented as an “ontological” or “metaphysical” thesis, in the pre-critical sense of the term. The goal of this study is to suggest that these two theses imply the tacit identification of the natural attitude and the phenomenological one, avoiding the difference between the objects to which these attitudes relate. Therefore, a phenomenological truth does not anticipate any opinion about the “world”.
The dawn of a new era of therapies in systemic lupus erythematosus
Authors: Mok Chi Chiu
Published: December 2020

Systemic lupus erythematosus (SLE) is a complicated multisystem autoimmune disease that is associated with significant mortality and morbidity in the younger population. The development of novel therapies of SLE lag behinds other autoimmune inflammatory rheumatic diseases because of its clinical and immunological heterogeneities, the complexity of outcome assessments in multiple systems, and difficulty in optimizing the design of clinical trials. Despite the futility of quite a number of clinical trials, we are seeing the dawn of novel therapeutics in SLE, given the promising results of the newer-generation anti-CD20, anti-CD40L biologics, and calcineurin inhibitors (CNIs), as well as anti-cytokine biologics, Jakinibs, and the mammalian target of rapamycin (mTOR) inhibitors. The initial success of the Jakinibs and combination regimens in SLE illustrates the importance of targeting multiple pathogenetic mechanisms. The results of the ongoing phase III clinical trials in SLE are eagerly awaited.

Published: December 2020

Late research has established the critical environmental, health and social impacts of traffic in highly populated urban regions. Apart from traffic monitoring, textual analysis of geo-located social media responses can provide an intelligent means in detecting and classifying traffic related events. This paper deals with the content analysis of Twitter textual data using an ensemble of supervised and unsupervised Machine Learning methods in order to cluster and properly classify traffic related events. Voluminous textual data was gathered using innovative Twitter APIs and managed by Big Data cloud methodologies via an Apache Spark system. Events were detected using a traffic related typology and the clustering K-Means model, where related event classification was achieved applying Support Vector Machines (SVM), Convolutional Neural Networks (CNN) and Long Short Term Memory (LSTM) networks. We provide experimental results for 2-class and 3-class classification examples indicating that the ensemble performs with accuracy and F-score reaching 98.5%.
Evaluating Suitable Glosa-Algorithms by Simulation Considering Realistic Traffic Conditions and V2X-Communication
Authors: Klöppel-Gersdorf Michael , Grimm Jan
Published: December 2020

Vehicle-to-Everything (V2X) communication allows infrastructure elements, e.g., traffic lights, to directly communicate with vehicles, thereby allowing services like Green Light Optimized Speed Advisory (GLOSA), Probe Vehicle Data (PVD), and Traffic Signal Priority Request (TSP). The idea behind GLOSA is to assist vehicles approaching an intersection with speed advices in order to fulfill a given objective, e.g., minimizing fuel usage, emissions and/or delay. In a prior work (Kloeppel et al., 2019), several GLOSA algorithms were examined and their fitness (in the form of CO2 emissions, fuel usage and delay) were evaluated under largely realistic conditions. This paper is an extension of the prior work and presents further examinations, which include a more detailed study on the behaviour of Diesel-powered vehicles when using the GLOSA algorithm of Stebbins et al. (2017) as well as a study considering fixed-time control coupled with intelligent vehicles.

Berdasarkan kelas perawatan, peserta kelas I (45,08%), kelas II (32,82%) dan kelas III (30,00%) belum memiliki akses ideal ke FKTP pilihan. Dapat disimpulkan bahwa 40,52% peserta JKN mandiri belum memiliki akses yang ideal ke FKTP pilihan. Informasi terkait lokasi FKTP terdekat perlu diberikan kepada calon peserta JKN sebagai pertimbangan dalam pemilihan FKTP.Keywords: JKN Mandiri, FKTP, Jarak Tempuh, Aksesibilitas, Kelas Perawatan

ABSTRACTImprovement of Primary Health Facilities (FKTP) in Badung Regency has not been accompanied by equitable distribution, where 48.39% (30) villages do not have yet FKTP in their area. This study aims to analyze the accessibility of FKTP selection for independent National Health Insurance (JKN) participants in Badung Regency. A cross-sectional descriptive study was conducted involving 385 independent JKN participants with street names and house numbers taken by systematic random sampling. Accessibility analysis is carried out using GIS. The variables studied were distance traveled, access by type of FKTP, and class of care. The results showed that 89.09% of JKN independent participants did not choose the closest FKTP. However, 54.52% of the selected FKTP participants are still in the ideal access category with an average distance of 4.71 km. Participants with the FKTP type pratama clinic (43.66%), general practice (29.17%) and puskesmas (33.96%) did not yet have ideal access. Similarly, participants in class I (45.08%), class II (32.82%) and class III (30.00%) did not have ideal access. In conclusion, 40.52% of samples do not have ideal access to FKTP. Information regarding the nearest FKTP location needs to be given to prospective JKN participants as consideration in the FKTP selection.Keywords : Health insurance, distance, accesbility

Kasus kelebihan berat badan merupakan salah satu masalah gizi terhadap masyarakat untuk semua umur terutama masyarakat di negara maju. Menurut beberapa penelitian, peningkatan jumlah kasus kelebihan gizi cenderung dialami oleh anak-anak prasekolah dan mereka berisiko menjadi orang dewasa yang kelebihan berat badan dan obesitas. Prevalensi anak yang kelebihan berat badan usia 3-6 tahun yang semakin meningkat dari tahun ke tahun. Tujuan dari penelitian ini adalah untuk mengetahui representasi dan faktor-faktor yang berhubungan dengan kasus anak prasekolah yang kelebihan berat badan. Penelitian ini menggunakan analisis cross-sectional dengan jumlah sampel 75 anak yang merupakan siswa di TK Denpasar barat; yang diambil dalam cluster sampling untuk menentukan sampel TK dan simple random sampling untuk menentukan ukuran sampel TK. Data dikumpulkan dengan metode wawancara dan dianalisis secara univariat dan bivariat. Hasil penelitian menunjukkan bahwa representasi kasus anak TK kelebihan berat badan di TK Denpasar barat adalah 20%. Faktor nilai yang mempengaruhi kasus anak TK kelebihan berat badan adalah konsumsi makanan cepat saji (PR = 2,98; p <0,0131), aktivitas fisik ringan (PR = 4,17, P = 0,0008), pemberian ASI eksklusif (PR = 0,34 ; p = 0,0184), status gizi ibu (PR = 4,61; p = 0,0013),, status kerja ibu (PR = 2,68; p = 0,0356). Kolaborasi orang tua, partisipasi sekolah, dan lingkungan banjar diperlukan dalam pencegahan kelebihan berat badan sehingga mereka dapat berperan aktif dalam mencegah anak sejak dini. Selanjutnya, jika peneliti ingin melakukan yang serupa dengan penelitian ini, diharapkan bisa lebih baik dalam mengukur aktivitas fisik dan asupan gizi responden.
