The field of tensions of a rotating anisotropic disc of a variable thickness loaded with undistracted forces on the outer contour
Authors: Karalevich Uladzimir V.
Published: August 2019

The work gives a solution of the plane elasticity problem for rotating polar-orthotropic annular disks of a variable thickness. The disk is loaded with a system of equal focused forces on the outer contour applied evenly along the rim and symmetric concerning the diameter. The disk is seated with an interference fit on the flexible shaft so that a constant contact pressure acts on the interior contour. The stresses and deformations arising in such a rotating anisotropic annular disk will be non-axisymmetric. A conclusion of a fourth-order partial differential equation for the effort function is drawn. Its general solution is searched out in the form of a Fourier series of cosines with even numbers. As a result, an infinite system of ordinary differential equations is solved for the coefficients of the series. These differential equations correspond to the linear Volterra integral equations of the 2 nd kind, which are solved using resolvents. Constants of integration are determined from the border conditions. Expressions for the stress components are written through the effort function by the well-known formulas. We find the components of the displacement vector in the disk by the integration of the Hooke’s law equations for the polar-orthotropic plate. We calculate the deformation components in a ring anisotropic disk by Cauchy differential relations if we know the displacements. The solved formulas for stresses, deformations and displacements completely describe the stress-deformed state in a rotating polar-orthotropic disc of variable thickness with a system of focused forces on the outer contour. The results of the work can be used in the design of working disks of turbomachines and turbo compressors, as well as rotors of centrifugal stands.

Authors: BAKLACI Deniz , GÜLER İsmail , KUZUCU İhsan , KUM Rauf Oğzuhan , ÖZCAN Müge
Published: August 2019

Objective: Nasal packs are commonly used after septoplasty. However,
there are numerous complications associated with nasal packing in the literature.
This study aimed to compare the efficacy of transseptal suture technique (TSS)
versus three different types of nasal packs regarding to postoperative
complications and patient satisfaction after septoplasty.  Material and Method: The study group included 80 patients who underwent
septoplasty. The patients were randomly divided into four groups: Merocel group
(group 1), internal nasal splint (INS) group (group 2), synthetic polyurethane
foam (SPF) group (group 3) and TSS group (group 4). The VAS scores of groups
were compared for pain (during pack, on removal of the pack), sense of
pressure, dysphagia and postnasal drip. The complications including bleeding,
synechiae, septal hematoma and septal perforation were also compared for each
group.  Results: The mean VAS scores of postoperative pain during packed and on
removal of packs, sense of pressure and dysphagia found significantly higher in
Merocel group than in silicone and Nasopore groups. There was no significant
difference between other three groups regarding to VAS scores. Bleeding ratio
was highest in Merocel group, and lowest in TSS group. Synechiae ratio was
highest in Merocel group followed by TSS and SPF groups and lowest in INS
group. There was no difference between groups regarding to septal hematoma and
septal perforation.

Conclusion: Our results showed that TSS technique might be safely used
in septoplasty patients regarding to high patient’s satisfaction and low
complication ratios. Merocel does not seem to be an appropiate material for
septoplasty due to its high complication and low patient’s quality of life
ratios.
Validation of the Persian Translation of the Children’s Test Anxiety Scale: A Multidimensional Rasch Model Analysis
Authors: Shoahosseini Roya , Baghaei Purya
Published: August 2019

In this study, we examine the psychometric properties of the Persian translation of the Children’s Test Anxiety Scale (CTAS) using the Rasch rating scale model. In the first step, rating scale diagnostics revealed that the thresholds were disordered. To remedy this problem, two categories were collapsed and a rating scale structure with three points turned out to have optimal properties. Principal component analysis (PCA) of standardized residuals showed that the scale is not unidimensional. Since the scale is designed to measure three distinct dimensions of test anxiety we fitted a correlated three-dimensional Rasch model. A likelihood ratio test showed that the three-dimensional model fits significantly better than a unidimensional model. Principal component analysis of standardized residuals indicated that three subscales are unidimensional. Infit and outfit statistics indicated that one item misfitted the model in all the analyses. Medium correlations between the dimensions was evidence of the distinctness of the subscales and justifiability of the multidimensional structure for the scale. Criterion-related evidence was provided by correlating the scale with the Spence Children’s Anxiety Scale (SCAS). The patterns of correlations provided evidence of convergent-discriminant validity. Findings suggest that a three-dimensional instrument with a 3-point Likert scale works best in the Persian language.
Securing Horticulture in a Changing Climate—A Mini Review
Authors: Bisbis Mehdi , Gruda Nazim , Blanke Michael
Published: August 2019

(1) Background: Climate change is on the rise due to continuous greenhouse gas emissions from anthropogenic activities ever since the industrial revolution. Changing weather conditions are likely to have consequences for horticulture. (2) Objective and Methods: A short literature review was conducted, gathering findings on climate change and the impacts on the yield and product quality of special crops. (3) Results: Global warming will result in elevated temperatures and CO2 concentrations in all seasons. Extreme weather events such as heat waves are also on the increase. In vegetables, physiological processes such as vernalization and winter chilling strongly rely on temperature. Therefore, heat stress may cause irregularities in yield production and planning the harvest. For fruit crops, frost poses a risk that is enhanced through climate change, as does a lack of chilling, as cold temperatures in the winter are required for flowering in the spring. Abiotic disorders in horticulture are also related to changing temperatures and humidity. The nutritional quality of special crops may be threatened by increasing rates of plant development and premature ripening at high temperatures. Quality traits such as sugars, acids, or antioxidant capacity may also shift as well. (4) Conclusions: Adapting to these new climate conditions means developing new climate-resilient varieties to maintain high production levels with superior quality. In this mini review, cultivation measures to mitigate adverse climate impacts are also discussed. Current developments and recent findings are presented, pointing out further steps toward adaptation and sustainable production.
Currency Crisis: Are There Signals to Read?
Authors: Islam Faridul
Published: August 2019

Financial crisis is nothing new in the annals of history of the capitalistic path of economic development; it is a part of the business cycle. The theoretical basis is well entrenched in the concept of ‘Keynesian Cross’. The tale of crisis, dating back centuries, has taken a new turn with the call for more globalization—liberalize trade and open up the financial sector. This has made many nations vulnerable to crises that are likely to be repeated, perhaps frequently. Based on recent experience, warning signs can be read from the dollar-centric exchange rate, the mainstay for the stability of the current global financial system. To a careful observer, fatigue in the system cannot be overlooked.
Exploring Learning Context Effects and Grapho(-Phonic)-Phonological Priming in Trilinguals
Authors: Blank Cintia Avila , Llama Raquel
Published: August 2019

A growing body of research on bilingual word recognition suggests that lexical access is language non-selective in nature. This claim aligns with the Dynamic Systems Theory (DST) approach to (multilingual) language acquisition, according to which complex systems involve a large number of elements that interact. In language learners, these interactions lead to the creation and dissolution of patterns as the tasks and environments around them change. In this study, we extend the scope from previous research on word recognition to include the role immersion plays on the transfer of grapho(-phonic)-phonological patterns among (Brazilian Portuguese–French–English) trilinguals. Two groups of participants—one group living in their L1 environment and the other in an L2 setting—were presented with a primed lexical decision task. Besides revealing a high impact of L2 immersion on the processing of grapho(-phonic)-phonological related primes, our results provide further support for the notion of language non-selective access to the lexicon, which seems to generalize to trilingual word recognition. Implications for the DST view of multiple language acquisition are briefly discussed.
iPSC Bioprinting: Where are We at?
Authors: Romanazzo Sara , Nemec Stephanie , Roohani Iman
Published: August 2019

Here, we present a concise review of current 3D bioprinting technologies applied to induced pluripotent stem cells (iPSC). iPSC have recently received a great deal of attention from the scientific and clinical communities for their unique properties, which include abundant adult cell sources, ability to indefinitely self-renew and differentiate into any tissue of the body. Bioprinting of iPSC and iPSC derived cells combined with natural or synthetic biomaterials to fabricate tissue mimicked constructs, has emerged as a technology that might revolutionize regenerative medicine and patient-specific treatment. This review covers the advantages and disadvantages of bioprinting techniques, influence of bioprinting parameters and printing condition on cell viability, and commonly used iPSC sources, and bioinks. A clear distinction is made for bioprinting techniques used for iPSC at their undifferentiated stage or when used as adult stem cells or terminally differentiated cells. This review presents state of the art data obtained from major searching engines, including Pubmed/MEDLINE, Google Scholar, and Scopus, concerning iPSC generation, undifferentiated iPSC, iPSC bioprinting, bioprinting techniques, cartilage, bone, heart, neural tissue, skin, and hepatic tissue cells derived from iPSC.
Viscovatov-Like Algorithm of Thiele–Newton’s Blending Expansion for a Bivariate Function
Authors: Li Shengfeng , Dong Yi
Published: August 2019

In this paper, Thiele–Newton’s blending expansion of a bivariate function is firstly suggested by means of combining Thiele’s continued fraction in one variable with Taylor’s polynomial expansion in another variable. Then, the Viscovatov-like algorithm is given for the computations of the coefficients of this rational expansion. Finally, a numerical experiment is presented to illustrate the practicability of the suggested algorithm. Henceforth, the Viscovatov-like algorithm has been considered as the imperative generalization to find out the coefficients of Thiele–Newton’s blending expansion of a bivariate function.
Antibiotic-Induced Perturbations Are Manifested in the Dominant Intestinal Bacterial Phyla of Atlantic Salmon
Authors: Gupta Shruti , Fernandes Jorge , Kiron Viswanath
Published: August 2019

The intestinal microbiota of certain farmed fish are often exposed to antimicrobial substances, such as antibiotics, that are used to prevent and treat bacterial diseases. Antibiotics that kill or inhibit the growth of harmful microbes can rapidly alter intestinal microbial diversity and composition, with potential effects on the host health. In this study, we have elucidated the impact of two antibiotics, florfenicol and oxolinic acid, by employing a high-throughput 16S rRNA gene amplicon sequencing technique on the distal and mid intestinal microbial communities of Atlantic salmon (Salmo salar). For this, Atlantic salmon were offered diets with or without antibiotics. We then investigated the bacterial communities in the intestinal mucus of the fish. Our results showed that antibiotic exposure shifts the intestinal microbial profile differentially. In addition, the bacterial compositions of the control and antibiotic-fed groups were significantly different. Antibiotic feeding altered the composition and abundance of the dominant bacterial phyla, namely Proteobacteria, Actinobacteria, Firmicutes, Spirochaetes, Bacteroidetes, Tenericutes, and Thermotogae. The bacterial association network analysis also indicated the differential pattern of co-occurrence of bacteria in the three study groups. The results regarding the differences in the structure and association of the intestinal microbiota of Atlantic salmon after florfenicol and oxolinic acid feeding can be employed to attenuate the adverse effects of antibiotic feeding on fish.

Authors: Anukam Anthony , Mohammadi Ali , Naqvi Muhammad , Granström Karin
Published: August 2019

The anaerobic digestion technology has been in existence for centuries and its underlying theory established for decades. It is considered a useful technology for the generation of renewable energy, and provides means to alleviate problems associated with low access to energy. However, a great deal of current research is targeted towards the optimization of this technology under diverse digestion process conditions. This review presents an in-depth analysis of the chemistry of anaerobic digestion and discusses how process chemistry can be used to optimize system performance through identification of methods that can accelerate syntrophic interactions of different microorganisms for improved methanogenic reactions. Recent advances in addition to old research are discussed in order to offer a general but comprehensive synopsis of accumulated knowledge in the theory of anaerobic digestion, as well as an overview of previous research and future directions and opportunities of the AD technology. Achieving a sustainable energy system requires comprehensive reforms in not just economic, social and policy aspects, but also in all technical aspects, which represents one of the most crucial future investments for anaerobic digestion systems.
Adjustable Robust Optimization for Planning Logistics Operations in Downstream Oil Networks
Authors: Lima Camilo , Relvas Susana , Barbosa-Póvoa Ana , Morales Juan M.
Published: August 2019

The oil industry operates in a very uncertain marketplace, where uncertain conditions can engender oil production fluctuations, order cancellation, transportation delays, etc. Uncertainty may arise from several sources and inexorably affect its management by interfering in the associated decision-making, increasing costs and decreasing margins. In this context, companies often must make fast and precise decisions based on inaccurate information about their operations. The development of mathematical programming techniques in order to manage oil networks under uncertainty is thus a very relevant and timely issue. This paper proposes an adjustable robust optimization approach for the optimization of the refined products distribution in a downstream oil network under uncertainty in market demands. Alternative optimization techniques are studied and employed to tackle this planning problem under uncertainty, which is also cast as a non-adjustable robust optimization problem and a stochastic programing problem. The proposed models are then employed to solve a real case study based on the Portuguese oil industry. The results show minor discrepancies in terms of network profitability and material flows between the three approaches, while the major differences are related to problem sizes and computational effort. Also, the adjustable model shows to be the most adequate one to handle the uncertain distribution problem, because it balances more satisfactorily solution quality, feasibility and computational performance.

Inteligencias múltiples y desarrollo de procesos cognitivos creativos
Authors: Guzmán Muñoz Estefanía Alejandra
Published: August 2019

La Educación tradicional se ha enmarcado en enseñar de forma memorística, aquellos aspectos que se han considerado claves en la formación profesional de los sujetos; en ese sentido se ha propendido al aprendizaje de ciertas asignaturas como matemática y lenguaje, dejando de lado otras que potencian las habilidades de los estudiantes y su capacidad de respuestas flexibles e innovadoras como desarrollo del pensamiento. Este trabajo de investigación tiene como objetivo comprobar la relación existente entre los niveles de creatividad y las inteligencias múltiples. El tipo de investigación es correlacional. Para la recolección de los datos se aplican dos cuestionarios el de Walter McKenzie (1999), en su adaptación para secundaria, el cual mide cada uno de los ocho tipos de inteligencias que plantea Gardner (1983) y el cuestionario de creatividad de Turtle (1980) obtenido en el programa diseñado para identificar/ diagnosticar a los alumnos de alta capacidad de Pacheco (2003). La población de estudio la conforman 30 estudiantes pertenecientes al tercero de bachillerato con una media de edad de 17.5 años del colegio Federico Gauss en la ciudad de Quito. En los resultados obtenidos se constató la relación existente fundamentalmente entre la creatividad y las inteligencias intrapersonal, cinestésica y visoespacial. Se encontró además que los estudiantes de este nivel educativo poseen altos niveles de creatividad y que la inteligencia que presenta un menor desarrollo es la lingüística, por lo que se sugiere analizar qué es lo que ocurre con este tipo de inteligencia, las actividades educativas que involucran el lenguaje y cómo los docentes incentivan o no este tipo de áreas. Se sugiere que en el futuro puedan involucrarse en este tipo de estudios otras acciones como el análisis del rendimiento académico de los estudiantes, la consideración del contexto social y cultural de forma que se pueda realizar una mejor y más exacta interpretación de los resultados obtenidos.

La práctica educativa actual debe promover el desarrollo de los ámbitos motriz, cognitivo, socio afectivo y lenguaje de los niños de 3 a 6 años y enlazarse emocionalmente al mundo exterior con el que se relaciona el niño. El currículo de educación inicial, promociona el trabajo en los ambientes de aprendizajes, pero la falta de creatividad y desconocimiento de la metodología para trabajar con los espacios de acción y aventura hacen que los objetivos estipulados para el desarrollo del ámbito de vinculación emocional, descubrimiento del medio natural y cultural, expresión artística, expresión del lenguaje verbal y no verbal, identidad y autonomía, convivencia, relaciones lógico matemáticos, expresión corporal y motricidad no se cumplan y se convierta en una simple rutina de aprendizajes que fácilmente se olvidan. La propuesta de crear estrategias de aprendizaje en espacios de acción y aventura en la que se realicen juegos de ejercicios, juegos de reglas y juegos simbólicos en conjunto con una dinámica de interacción entre los niños y el adulto favorecen el ejercicio funcional, la comunicación interpersonal y el desarrollo de competencias. Los niños serán capaces de establecer su propio ritmo de descubrimiento en un medio, material y humano, para ampliar progresivamente sus aprendizajes en número y complejidad. Las estrategias de acción y aventura como propuesta educativa garantizan a la docente seguridad durante la sesión y los niños puedan manifestar su espontaneidad y actualizar sus potencialidades en un marco de organizada libertad, que repercutirá en el clima general del aula y el ambiente de aprendizaje.

Hoy los medios de comunicación globales socializan desde la cuna a una poblacióninfantil favoreciendo una condición trasnacional, estereotipada, occidentalizada, consumista y fragmentada, acostumbrándola a altos niveles de calidad gráfica y dinámica, a altos ritmos y excesos de emocionalidad y saturación de sentidos, factores que pudiesen estar contribuyendo a facilitar el desarrollo de ciertas conductas sociales vinculadas a la violencia y su cultura o subcultura, dirigida a satisfacer las “necesidades del consumo de todo tipo” sin asumir verdaderas responsabilidades, con poca capacidad para afrontar en primera persona la realidad, con obligaciones y dispuestos a sacrificarse para construir algo duradero y colectivo. Ante esto la tarea de los facilitadores y maestro es la de asumir la educomunicación critica y activa.

The development of the spinning wheel in ancient China
Authors: JUE RAO , CHENG LONGDI , LIU YUNYING
Published: August 2019

As textile demand increased in ancient China, the spinning wheel became more widely used in the Neolithic era and
was responsible for the main spinning tasks over the last few thousand years. This work explores the changes over time
in the shape, diameter, and thickness of the spinning wheel in the Cross-lake Bridge, Hemudu, Yangshao, Qujialing, and
Shijiahe cultures. The disc-like shape, mound-like shape, bead shape, and truncated cone shape are deemed to have
been the best spinning wheel forms in the later stages – especially the disc-like spinning wheel. The spinning wheel with
a diameter of 2–9 cm and a thickness of 0.1 to 9.0 cm was used throughout prehistoric times. In the late Neolithic period,
a disc-like spinning wheel with a diameter of 3–4 cm and a thickness of less than a cm was the most frequently used
design. This study shows that the change in the shape, diameter, and thickness of the spinning wheel is the inevitable
result of the change in the tool’s design points, thereby revealing improvements in spinning efficiency

Making software requires a lot of algorithms that are implemented into the making, one of the algorithms used is the sorting algorithm. Algorithms are logical sequences of steps to solve problems that are arranged systematically. Sorting algorithms (sequencing) are generally defined as the process of rearranging a series of objects in a certain order. The purpose of the sequencing process is to facilitate the search process for a beginner who wants to learn to make software, of course they have to go through stages in learning algorithms and in the learning process there will usually be obstacles faced such as not fully understanding how the algorithm works, especially the sorting algorithm or the media used as learning materials have not been able to maximize the knowledge of sorting algorithms, therefore it requires an application of learning aids media that can help in learning and understanding the material of the sorting algorithm more optimally. In making assistive media applications learn how to work the steps of the sorting algorithm, the author uses the luther-sutopo method. The stages are concept, design, collecting materials, assembly, testing, and distribution. In the application there is general material about sorting and video algorithms that can help maximize understanding of the sorting algorithm material. The results achieved by an auxiliary media application are learning desktopbased sorting algorithms that are used for learning specific sorting algorithms in theory

Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. Nicotinic acid derivatives such as isoniazid have the strongest anti-tuberculosis properties. For pharmacokinetics studying of isoniazid (INH), a method is needed to determine the levels of INH in plasma. Objective: The aim of this research is to partial validate of high performance liquid chromatography (HPLC) for analysis of INH in rat plasma. Method: For the preliminary study, rat plasma was used. The HPLC system used is a stationary phase C18 with length 250mm and temperature of 30°C, mobile phase hexane sulphonate acid 20mM pH 2.47–methanol (65:35). The analytical parameters in partial validated were linearity, lower limit of quantification (LLOQ), precision, accuracy, and recovery. Results: The results of linearity test of INH showed r value of 0.9996. LLOQ of this method was 0.1258μg/mL. The resulting accuracy and precision value met FDA requirements with a percent recovery ranging from 96.57–107.99%. Conclusion: The HPLC system was a valid method for analysis of INH in rat plasma.

Evaluasi yang dilakukan dalam penelitian ini meliputi praktek penerapan akuntansi aset biologis pada entitas akuntanbilitas publik sesuai dengan standar akuntansi yang berlaku di Indonesia.Metode penelitian yang digunakan dalam penelitian ini menggunakan metode kualitatif. Penelitian dilakukan selama periode bulan Februari-Juni 2018. Wawancara kepada informan dilakukan pada Minggu pertama dan kedua bulan Mei 2018. Informan dalam penelitian ini adalah pemilik perusahaan yang sekaligus pimpinan perusahaan yang menjalankan bisnis proses perusahaan. Item pertanyaan yang diajukan terkait dengan tentang kebijakan pengakuan, pengukuran, pencatatan, dan penyajian akuntansi aset biologis yang diterapkan oleh perusahaan.Hasil penelitian menunjukkan bahwa pencatatan akuntansi yang telah dilakukan oleh CV Sumber Berkat masih tergolong sederhana. Hasil pencatatan akuntansi yang telah dilakukan masih kurang handal jika dijadikan dasar membuat keputusan manajemen perusahaan. Pelaporan keuangan yang diterapkan oleh CV Sumber Berkat khususnya dalam mencatat transaksi aset biologis kurang menggambarkan keadaan yang sebenarnya terjadi di perusahaan. Secara keseluruhan perlakuan akuntansi aset biologis yang dilakukan CV Sumber Berkat berbeda dengan perlakuan akuntansi aset biologis yang ada di SAK 69 (2015) seperti pengakuan beban penyusutan yang kurang sesuai dan perusahaan belum mengakui nilai produk telur yang dihasilkan.

This study aim to propose a software costing for public sector, by using both of activity-based costing (ABC) method and traditional costing method. We based on a case study in Pusintek, Ministry of Finance and using a field observation, interviews and literature studies to collect data and information such as related to the preparation of software costing simulations. Finally, we proposed a software costing by ABC method and traditional costing method for Pusintek. We find that the software costing by ABC is cheaper than traditional costing, however the ABC costing takes more assumption and more complex calculations. We have several limitation related to lack of data, use more assumptions and find a complicated of data’s segregation. We suggest to use traditional costing to calculate the software cost, because traditional costing is simpler and practicable in the public sector, since the degree of complexity is lower than ABC costing. The ABC has more accurate cost calculation, but it considers more assumption, need more documents, and higher complexity of job’s procedures. In the public sector, it was still a lack of requirement to apply the ABC.
PERILAKU SEKS AMAN (SAFE SEX) PADA WANITA PEKERJA SEKS (WPS) YANG TERINFEKSI HIV DALAM MELAYANI PELANGGAN DI KOTA YOGYAKARTA
Authors: Fika Lilik Indrawati Casnuri,
Published: August 2019

Abstrak: Salah satu faktor risiko tingginya penularan HIV adalah banyaknya pelanggan yang dilayani seorang wanita pekerja seks (WPS) yang sudah terinfeksi HIV. Semakin besar jumlah pelanggan, semakin besar kemungkinan tertular HIV. Sebaliknya jika WPS telah terinfeksi HIV, maka makin banyak pelanggan yang mungkin tertular darinya. Dilain pihak, sedikitnya jumlah pelanggan dapat memperlemah kekuatan negosiasi WPS untuk pemakaian kondom, karena mereka takut kehilangan pelanggan. Dalam posisinya sebagai penjaja seksual, serta kurangnya pengetahuan tentang kesehatan reproduksi, maka WPS dengan tanpa sepengetahuannya akan mudah menularkan virus HIV kepada pasangan-pasangan berikutnya. Hal itu terjadi karena kurangnya informasi tentang kesehatan reproduksi dan seksual serta akses tentang layanan kesehatan bagi WPS. Penelitian ini bertujuan untuk memahami perilaku WPS dalam melakukan seks aman (safe sex) sehingga dapat diketahui proses serta faktor yang melatarbelakangi perilaku WPS melakukan seks aman (safe sex) dalam melayani pelanggannya. Penelitian ini menggunakan pendekatan kualitatif dengan pendekatan fenomenologi, teknik pengambilan sampel secara purposive sampling jenis criterion based sampling dan snowball sampling dilakukan dengan menemukan orang yang dapat memberi petunjuk mengenai orang yang bersedia menjadi subjek penelitian sesuai dengan kriteria. Dari kriteria-kriteria yang telah dirumuskan, diperoleh lima orang informan yang representatif. Teknik pengumpulan data menggunakan wawancara mendalam. Hasil: bahwa hampir semua WPS mempunyai pengetahuan yang kurang tentang HIV/AIDS. Mereka tetap melakukan hubungan seksual yang beresiko meskipun sudah dinyatakan positif HIV dan sudah mengetahui beberapa teman WPS yang terkena HIV/AIDS. Semua WPS merasa bahwa pekerjaan mereka beresiko untuk menularkan HIV. Secara umum keseriusan/keparahan jika pelanggan tertular HIV yang dirasakan adalah merasa kesakitan secara fisik, malu, menyesal serta kehilangan pekerjaan. Manfaat melakukan seks aman (safe sex) adalah rasa aman untuk tidak menularkan HIV kepada pelanggan. Secara umum penolakan pelanggan terhadap pemakaian kondom tidak menjadi hambatan bagi WPS. Kesimpulan: Semua WPS percaya bahwa melakukan seks aman (safe sex) dapat menguntungkan bagi mereka dan pelanggan.Kata kunci : seks aman (safe sex), WPS, health belief mode
