A holistic framework for the perceived return on investment in an MBA
Authors: Carmichael T. , Sutherland M.
Published: July 2019

Traditional models for calculating the Return on Investment (ROI) of education examine the costs and benefits of such interventions in financial terms. The aim of this study was to explore other important variables over and above those of a financial nature, which should be considered by MBA students when holistically evaluating the ROI of undertaking this qualification.The study was exploratory and perception based; a pilot contribution to the debate on the value of an MBA and a baseline for further research. In the two-phased study, 54 graduates from Wits Business School articulated a number of input (cost), output (benefits) and process variables that they perceived as important when holistically evaluating the ROI of their studies. An overwhelming majority perceived that the benefits of doing an MBA outweigh the costs, taking all variables into account.Although the findings cannot be generalised to a wider population, a transformation model has been proposed. MBA students and learning facilitators may find this useful when planning MBA programme participation or facilitation, so that students gain the greatest possible value from the undertaking.

Authors: Horwitz F. , Ferguson M. , Rivett I. , Lee A.
Published: July 2019

This exploratory study examines perspectives of multinational corporations (MNCs) from South Africa (SA) in respect of the variables considered important in product and labour markets in China. These include how MNCs first interpret and understand cultural, human capital, regulatory factors and employment practices, before considering how they might adapt to or seek to influence them. A survey of thirteen SA firms operating or trading in these markets and interviews with South Africans who had undertaken exploratory assignments in China, were done. Key factors were identified and evaluated based on relevant literature and research. The following six focus areas were found to be important for business effectiveness in this market: understanding its market complexity, importance of joint venture partners, guanxi relationship networks, human capital, language and culture, and regulatory environment.
Knowledge management in project environments
Authors: Pretorius C. J. , Steyn H.
Published: July 2019

Knowledge management is widely acclaimed to be a source of considerable financial advantage for organisations. Various authors realise that project environments could also benefit from the creation and re-use of knowledge, including from the lessons learned that should be documented during project close-out. Projects face specific challenges (limited time spans, changing and dispersed teams) and the reduction of project risk, time and cost through knowledge management, may well prove worthwhile.This paper reviews the literature on knowledge management, both in organisations in general and in project environments specifically. A framework for knowledge management is derived from literature. The paper also reports on an investigation of knowledge management practices in four cases within a single South African business environment. Knowledge management practices similar to ones reported abroad were found.A model is proposed for the management of knowledge in project environments, both within a single project (intraproject) and between projects (inter-project) and. guidelines for knowledge management in project environments are provided. It is also suggested that, while the management of explicit knowledge is common in project management, more attention should be given to the sharing of tacit knowledge through human interaction.
AIDS and sexuality education in the physiotherapy curriculum
Authors: Amosun S. L. , Shabodien R. , Marais M. , Nicholas L. J.
Published: July 2019

The need for physiotherapy in the multidisciplinary management of patients with AIDS is generally acknowledged. Physiotherapists should understand the disease, and develop appropriate attitudes towards individuals with AIDS. Data obtained from questionnaires completed at the University of the Western Cape by prospective physiotherapy students between 1991 and 1993, on knowledge of and attitudes about AIDS, were analysed. The same questionnaire was re-administered to a group of physiotherapy students completing their fourth-year of study. Although most of the students indicated accurate knowledge about AIDS, their attitudes were uncertain. Students expressed anxiety about contact with persons with AIDS. The findings suggest the need for the inclusion of AIDS education in the physiotherapy education curriculum at the University of the Western Cape.

Authors: Eales C. J. , Stewart A. V.
Published: July 2019

There is a very high incidence of hypertension amongst the black population in South Africa. Regular aerobic exercise has been shown to be an effective method of lowering blood pressure. In order to be able to prescribe exercise for patients in a community-based setting, an easily administered exercise test needs to be used. In this study the 6 minute walking test in conjunction with the Borg scale and the Duke Activity Status Index (DASI) were tested on three groups of hypertensive patients from different socio-economic communities. The mean age of the cohort was 64.1 years (SD+-7.9) and males and females were included. The outcome was evaluated by determining the degrees of agreement between the DASI and the age predicted V02max (-0.3295) as well as between the calculated V02max and the age predicted V02max (-0.3045). The tests were easy to administer and the calculations easily done. The agreement between the 6 minute walking test and the DASI test was clinically acceptable (-0.0250). There was no agreement between the values obtained and the age-predicted values. It was concluded that the walking test is a useful field test for exercise performance

Published: July 2019

Six Chlorophyta strains were isolated from the effluent of an anaerobic reactor treating municipal wastewater and identified as Desmodesmus sp. L02, Chlorococcum sp. L04, Coccomyxa sp. L05, Chlorella sp. L06, Scenedesmus sp. L08 and Tetradesmus sp. L09. The microalgae strains were cultivated in unsterilized wastewater under laboratory conditions to determine their potential to survive under non-sterile conditions. The strains were also cultivated in sterilized wastewater in order to analyze their nutrient removal potential and characterize the produced biomass. Amongst the isolated microalgae, Chlorella sp. L06 had the highest survivorship percentage (90%) for ten days of culture, whilst Desmodesmus sp. L02 had the lowest, not exceeding 1.8% after 24h of inoculation. The dried biomass of the isolates showed an average of 28.7% of protein, 15.4% of lipids and 14.8% of carbohydrates, with Chlorococcum sp. L04 reaching 29.3% of carbohydrates. In terms of nutrients, nitrogen removal varied from 59.2 to 93%, and phosphorus removal ranged from 79.1 to 95.4%, with Tetradesmus sp. L09 being the most efficient strain.

Introduction

Health care delivery is contingent on efficient communication among providers. We hypothesized that using smart-device two-way communication would result in faster provider responses when compared with alphanumeric paging among resident physicians in an academic medical center.

Methods

Resident physicians were given an Apple iPad Mini smart device with a Health Insurance Portability and Accountability Act-compliant smart-device two-way communication application. Patient care messages were randomized for transmission via smart-device two-way texting or standard one-way paging. Physician response time was recorded as the primary outcome measure.

Results

The study was halted after participation of the first 24 residents due to safety concerns. A technical glitch was identified in which the smart devices automatically powered off to conserve battery life. The first 72 smart devices to first 37 pager communication response times were similar (8 vs 6 minutes, p = 0.43). In analysis of responses within 5 minutes of communication (the time smart devices powered off), smart-device responses occurred significantly faster (1 vs 2 minutes, p < 0.05) but the response frequency was less in the smart-device group (33 vs 62%, p< 0.05), and thus the study was ended early due to safety concerns.

Discussion

Based on our initial findings, smart devices have potential to improve communication but technical issues must be addressed prior to usage as the sole means of communication.

Published: July 2019

Patients undergoing a revision total hip arthroplasty (THA) are at increased risk for dislocation. The literature suggests dual-mobility components may decrease the frequency of dislocation. We conducted a retrospective study of one type of dual mobility acetabular component implanted in 82 revision THA cases that were considered at increased risk for dislocation. Of the 82 hips, 58 had a mean follow-up of 12 months (3–28 months). The indication for revision was instability in 18 hips (31%), adverse metal-on-metal reaction in 13 hips (22%), reimplantation for infection in 11 hips (19%), and aseptic loosening of the acetabular component in 9 hips (16%). In the course of follow-up, 6 hips developed a deep infection requiring reoperation. There were no early hip dislocations.

Authors: Zhang Xu , Xiao Zuohui , Wang Haorong , Kishen Anil
Published: July 2019

Dentin is a composite hard tissue, comprising of inorganic and organic matrices, and regulated by many proteins during development. The demineralization of dentin results from the loss of inorganic matrix [mainly hydroxyapatite (HAP)], but the organic matrix (mainly type I collagen) will sustain for a period of time after demineralization. Over the past decade, there has been a growing interest on the remineralization of demineralized dentin, primarily in connection with minimally invasive caries management. More and more biomaterials and methods are currently being evaluated to achieve newer approaches for the remineralization of demineralized dentin. These strategies are mostly based on biomimetic approaches and aim to achieve the characteristics of natural hard tissue. This article will present a complete review on the basic compositions and properties of dentin, which formed the basis for the biomimetic remineralization of demineralized dentin.

Pain Management in Endodontics
Authors: Pradeepkumar Angambakkam Rajasekaran
Published: July 2019

Management of dental pain during and after endodontic treatment remains a big challenge. Dental anxiety can also influence the patient's perception of pain and is known to directly lower the pain threshold. Psychological intervention in acute dental pain may be a very effective noninvasive measure to reduce pain. However, the pulp that has been diagnosed with irreversible pulpitis, with spontaneous, moderate-to-severe pain may not respond to the local anesthetic (LA) enough for the operator to pursue a pain-less treatment. In this review, pain predisposing factors and pain prevention techniques are evaluated, and various strategies to overcome anesthetic failures are reviewed which will help the practitioner achieve effective pain management.

Thyroid Status in Patients with Dysfunctional Uterine Bleeding in a Tertiary Care Hospital of Assam
Authors: Phukan Jadab K , Saharia Gautom K , Goswami Rohini
Published: July 2019

Background

Dysfunctional uterine bleeding (DUB) is a major form of abnormal uterine bleeding, seen in at least 10% of all new outpatient department patients. The thyroid gland is known to play an important role in maintaining a healthy menstrual cycle.

Aims

To assess the thyroid hormone status in apparently euthyroid patients with DUB and to correlate it with incidence of DUB.

Materials and methods

Fifty DUB patients were selected on the basis of clinical history, examination, and relevant investigations. Equal numbers of age-matched women with normal menstrual cycle were taken as controls. Thyroid hormones, viz., thyroid-stimulating hormone, total triiodothyronine and tetraiodothyronine, were estimated by radioimmunoassay. Statistical analysis of the data was performed by using Microsoft Excel software.

Results

The most common menstrual abnormality was menorrhagia (48%) followed by metrorrhagia and polymenorrhea (14% each). Hypothyroidism was more prevalent among cases (85.7%) as compared with controls (14.3%). In patients with menorrhagia, 33.3% of patients had hypothyroidism.

Conclusion

Hypothyroidism occurs in DUB patients commonly. There is a need for mandatory thyroid screening in all patients with menstrual irregularities to help in early detection of the cause and treatment of DUB patients to avoid surgery.

Published: July 2019

Iodine deficiency disorders (IDDs) constitute a major public health problem in India. Goiter occurring in a large fraction of population (> 10%) is said to be due to iodine deficiency rather than any other cause. A community-based cross-sectional study was undertaken in the Union Territory of Chandigarh with the aim to track the elimination of IDD to determine the iodine status of school children unexamined for goiter status and excretion median urinary iodine concentration. Goiter was assessed by standard palpation technique in 6,517 school children, aged 6 to 12 years, selected through 30 cluster sampling methods. Spot urine samples of 823 children were collected for estimation of urinary iodine using modified method of Sandell and Kolthoff. Household salt samples of the 548 selected children from schools were analyzed for its iodine content by standard iodometric titration method. The overall prevalence of goiter was found to be 14.2% among the children examined. The median urinary iodine excretion (UIE) was 199 g/L. About 71.2% of the salt samples were adequately iodized, having iodine content of > 15 ppm. Since UIE reflects recent iodine nutrition at the time of measurement and thyroid size shows iodine nutrition over months or years, it can be said that this region is in transition phase from iodine-deficient to iodine-sufficient territory.

Published: July 2019

Objectives

Epilepsy is a significant public health problem in the world today. The social stigma and impact on quality of life (QOL) may pose a bigger challenge than the clinical severity. In India, there are not many studies using quality of life in epilepsy (QOLIE-31) questionnaire to study the QOL in epileptic patients. This study may be useful in planning the management of patients with epilepsy. So, our study was conducted to determine the level of health-related QOL (HRQOL) of patients with epilepsy in a teaching hospital.

Materials and methods

This was a cross-sectional, questionnaire-based study conducted in a teaching hospital from March to October 2015. The subjects included both male and female adults of at least 18 years of age with a diagnosis of epilepsy, which was present for minimum 1 year. The QOLIE-31 was used for collecting data on HRQOL.

Results

Totally, 70 patients with epilepsy were included in the study. The standard deviation (mean) total score of QOLIE-31 in our study was 60.46. There was a significant difference in the total score of QOLIE-31 within the monotherapy and polytherapy group as the total score of QOLIE-31 was better in monotherapy group as compared with polytherapy group.

Conclusion

The study revealed that patients who were on a single drug (monotherapy) had a much better QOL than the patients on more than one drug (polytherapy).

Published: July 2019

Introduction and objectives

Chronic inflammatory gingival enlargement also called as chronic hyperplastic gingivitis is an enlargement of the gingiva as a result of chronic inflammation due to local or systemic factors; most important local factor appears to be the dental plaque and calculus. This case report aimed to present the clinical, histopathological features and treatment of inflammatory gingival enlargement which disturbed the esthetics and masticatory function of the patient.

Materials and methods

A 34-year-old male patient reported with a chief complaint of swelling and bleeding in the gums of teeth in maxillary and mandibular anterior region. The enlargement was firm and fibrotic accompanied by an inflammatory component probably due to inability to maintain adequate personal oral hygiene. Periodontal surgical therapy was performed for good esthetic outcome.

Results and interpretation

No recurrence was reported 6 months postsurgery. The importance of patient motivation and compliance during and after therapy as a critical factor in the success of treatment has also been highlighted through this case report.

Conclusion

Gingival overgrowth interferes with mastication and speech of the patient. A thorough diagnosis and treatment planning is essential.

Smile Design with All Ceramic Veneers
Authors: Soni Dileep , Prasad Ashwani B
Published: July 2019

The use of porcelain laminate veneers to solve esthetic and/or functional problems has been shown to be a valid management option, especially in the anterior esthetic zone. In cases when patients decline orthodontic treatment, adhesively bonded porcelain veneers are a reliable treatment option to modify the appearance of tooth position and form, to close diastema or cervical embrasures, or to change the tooth shade. Porcelain veneers are one of the best corrective options available considering biological, functional, mechanical, and esthetic points of view. The present case report is about discolored anterior teeth in a healthy dentition by means of sectional porcelain veneers simply cemented onto the natural teeth and with minimal tooth preparation.

Published: July 2019

Thermal insulation inside the rocket motor experience severe pressure and temperature conditions. Experimental determination of heat flux imparted to thermal insulator inside the rocket motor during the static firing is a challenging task. This paper reports experimental determination of heat flux for double base propellant (DBP) in small rocket motor. It includes development of experimental rocket motor, adaptation of water-cooled heat flux sensor on rocket motor, required instrumentation for heat flux time recording and analysis of data. Data are recorded in real time for double base propellant combustion up to the pressure level ~3.6 MPa. Average heat flux imparted to the rocket motor casing is found in the range of 230–300 × 104 W/m2. Heat flux inside the rocket motor varies nearly linear with pressure. A correlation between the heat flux and pressure is also established for measured pressure range.

Abstract. The efficiency of natural and artificial selection is critically dependent on the recombination rate. However, interbreed and individual variation in recombination rate in poultry remains unknown. Conventional methods of analysis of recombination such as genetic linkage analysis, sperm genotyping and chiasma count at lampbrush chromosomes are expensive and time-consuming. In this study, we analyzed the number and distribution of recombination nodules in spermatocytes of the roosters of six chicken breeds using immunolocalization of key proteins involved in chromosome pairing and recombination. We revealed significant effects of breed (R2=0.17; p<0.001) and individual (R2=0.28; p<0.001) on variation in the number of recombination nodules. Both interbreed and individual variations in recombination rate were almost entirely determined by variation in recombination density on macrochromosomes, because almost all microchromosomes in each breed had one recombination nodule. Despite interbreed differences in the density of recombination nodules, the patterns of their distribution along homologous chromosomes were similar. The breeds examined in this study showed a correspondence between the age of the breed and its recombination rate. Those with high recombination rates (Pervomai, Russian White and Brahma) are relatively young breeds created by crossing several local breeds. The breeds displaying low recombination rate are ancient local breeds: Cochin (Indo-China), Brown Leghorn (Tuscany, Italy) and Russian Crested (the European part of Russia).

Authors: Pillay Larissa , Schaab Gertrud , Coetzee Serena , Rautenbach Victoria
Published: July 2019

Abstract. The increase in massive volumes of point data that are continuously being generated calls for more powerful solutions to analyze and explore this data. Very often, such data includes a direct or indirect reference to a location on the Earth and can then be referred to as ‘big geospatial data’. Maps are one of the best ways to assist humans with understanding geospatial relationships in such data. In this paper, we present a comprehensive workflow for generating all possible thematic map types from two-dimensional univariate big geospatial point data. The objective is twofold: to facilitate and support thematic map automation, and to make this information accessible to software developers. The workflow illustrates processing steps, design choices and dependencies between them based on the characteristics of input data. Processing steps and design choices that can be automated and those requiring human intervention are identified. The scope of the workflow in this paper was restricted to two-dimensional univariate geospatial point data and planar and true geometrical map depictions. The results presented in this paper support the development of geovisualization and geovisual analytics tools for big geospatial data.

Published: July 2019

Abstract. For millions of years, the Jarama Valley, located in the middle of Spain, has fluctuated physically and geomorphological, supposing over the centuries a crucial settlement for wildlife and different human cultures as an efficient route through South Europa. Currently, this scenario, which consist of a vast and intricate network of military installations due to the Battle of Jarama in the Spanish Civil War, mixed with incredible paleontological sites, Celtiberian cities and roman, are part of a great-protected natural and cultural classified as the Southeast Regional Park close to Madrid City.The aim of this work is developing a geospatial methodology for the digital heritage mapping in the Jarama Valley using geomatics’ technologies in situ, drones' data, image spectrometry and the Copernicus European program, both their active and passive sensors. Data from Sentinel 1, Sentinel 2 and airborne sensors have analysed according to remote sensing techniques to recognize the potential remains and to reconstruct the heritage landscapes of three test areas in the Jarama Valley. We have investigated the spectral characteristics of main biophysical parameters in the pattern recognition of man-made materials in several remote sensing scenes of the Jarama Valley. Spectral ranges from drones' data are used to validate data cubes from multisperspectral sensor ATM. Sentinel 1 polarimetric products and thermal anomalies have calculated in order to contrast evidences of buried remains and confirm land change detection over the last decades. First results and their consequences on the digital heritage mapping of the Jarama Valley are discussed, representing a first point of protection and an advance of a full cultural and natural heritage research project in this region.

Published: July 2019

Abstract. Croatia is a country rich with monuments, enchanting historic buildings, and rife cultural heritage. The paper presents main aspects of the research on the identifying the historic bridges built till the end of the Austro Hungarian monarchy (AHM) (till 1918), and by their identification, the inventory of these bridges was established. The Croatian territory, specifically, Dalmatia is brimming with rivers, lakes, streams, etc., so the bridge construction was indeed necessary and often in usage in this area. There are various reasons why all these bridges are not preserved until today. Because of this, authors found it important to define the total number of these bridges that will need further qualitative and sustainable preservation, remediation and management. The research started by collecting the data from various institutions and interviewing conservatives, historians, managers of these bridges and also the local habitants. When the data were collected, European maps from the XIX. Century were analyzed with the intention to find which of the identified bridges belong to the period of the AHM. Bridges found on those maps were later compared with modern maps to define how many of them still exist. The aim is to establish the inventory of the historic bridges built till the end of the AHM in the area of Split-Dalmatian County.

Abstract. Related to the implementation of regional autonomy (UU No. 32 Tahun 2004), the determination of regional boundaries is one of the main factors in the implementation of regional government functions. Regional boundaries that are not clear at the border can trigger conflicts that can obstruct the development of society. The conflict is not only limited to social conflicts, but also conflicts in the administrative affairs of population and local government. If it is not immediately resolved, it can reduce the level of government service to the community. Remote sensing image technology and cartography become one of the options that can help facilitate in terms of cost efficiency and time effectiveness for mapping regional boundaries. This study utilizes remote sensing image to map regional boundaries using the cartometric and participatory methods. By drawing boundaries on work maps and measuring the position of points, distances and area coverage by using basic maps and other maps as a complement and also with verification from the local government as the participator to withdraw the limit. With the cartometric and participatory method and the help of remote sensing imagery in this study that can minimize field activities with the terms of the image used has a higher resolution than the base map used. The results of this study are the map Kaligesing sub-district boundary of Purworejo District, Central Java, that that has been verified. This verified map will be used for identifying the extend differences of this area, by comparing it to the Administration Map provided by the national government. Except that the result can be use to another research such as to boundary unit of disaster, or to make cadastral map in village level.
Caveat Emptor: A new form of participatory mapping and its ethical implications for Participatory GIS
Authors: Suzuki Koshiro
Published: July 2019

Abstract. Since the 1990s, the consolidation of technological platforms for geographic information has expanded the possibilities of geospatial analysis in conjunction with GIS. Even ordinary people have become capable of interactive web communication with electronic maps thanks to the emergence of smartphones compatible with GeoAPI (application programming interface) and Wi-Fi access. Many studies have described the progress that built a solid foundation of web democracy by embodying people-powered mapping circumstances in the so-called Web 2.0. However, we have yet to acquire geographic information ethics that sufficiently respond to new threats stemming from these circumstances. In the present paper, the author instantiated a user-generated online mapping website named Caveat Emptor (a.k.a. Oshimaland) to investigate the necessity of a geographic information ethics 2.0. By incorporating Suler’s (2004) concept of online disinhibition effects, the author clarified that people can utilise new technologies both in good ways and bad, from behind the safety of a mask. Despite the omnoptic mutual surveillance environment, the associated participants in actual scenes of cyberspace are not always restrained. This explains why it is necessary to update geographic information ethics to be compatible with Web 2.0 circumstances. Four types of ethical challenges were identified that are concerned with (1) the extent to which volunteered geographic information (VGI) should be recruited in constructing collective knowledge, (2) how to build a renewed geographic information ethics in general, (3) how to construct a gradation in geographic information ethics in practice, and (4) what scientific knowledge should be referred to in the contiguous areas of specialisation.
A Multi-Criteria Decision Support System in the Analysis of Flood Risk and Vulnerability Mapping in Suleja, Niger State, Nigeria

Published: July 2019

Abstract. This study aims at assessing flood risk factors and mapping areas vulnerable to flood in Suleja of Niger State, Nigeria, using Geo-spatial techniques. The method follows a multi-parametric approach and integrates some of the flood causative factors as: rainfall distribution, elevation and slope, drainage network and density, landuse/ land-cover and soil type. The Spatial Multi-Criteria Analysis (MCA) was used to rank and display potential locations, while the Analytical Hierarchy Process (AHP) method was employed using pair-wise comparison to compute the priority weights of each factor. The various layers were integrated in weighted overlay tool in ArcGIS to generate the final vulnerability map (high, moderate and low). The normalized criterion weights were obtained for each factor, and the results shows that, rainfall (34) and slope (31) have the highest influence on flood in the study area. The Consistency Ratio (CR) with an acceptable level of 0.05 was obtained which further validated the strength of the judgement. The factor weights from the AHP were incorporated to produce a Geo-hazard map and it showed that areas that are high vulnerable to flood in Suleja constitute about 37%, while moderate and low vulnerable areas constitute about 45% and 18% respectively. Elements at high risk of flood are those found at the extreme northeast, where elevation is very low, southwest where rainfall distribution is high and on low lying areas along the depressions. Therefore using the Geo-hazard map as a guide, local councils and other stakeholders can act to prepare for potential floods.
Improving the search for victims in mountain environments with geovisualization and competing hypotheses management

Published: July 2019

Abstract. This article is part of a research program aimed at improving the location of victims in the mountains. The search for victim location is a process involving various elements, few of them falls within the scope of our team such as the modelling of the process of spatial reasoning of the rescuer and the geovisualization of multidimensional and uncertain information for decision-making. After having reviewed the various scientific challenges we propose a prototype of interface. The strengths of our approach are the transformation of location clues into a list of spatial filters, the addition of these filters within a search scenario to create probable location area(s) as well as the simultaneous management of competing search scenarios. We also present the results of user tests, validating the interest of such an approach to objectify the area of probable location of the victim and obtain a more precise area than during the traditional search approach. Finally, we will discuss the improvements underway on the basis of this prototype, in particular how we plan to better account for the uncertainty in the decision-making process and how we plan to allow a future prototype to suggest questions to the rescuer in order to help him/her refine his/her research.
Examination of car navigation systems and UX designs – suggestion for a new interface

Published: July 2019

Abstract. The need for car-related navigation and the appearance of the vehicles themselves are much the same age – of course. In the early days, paper maps and personal questioning were solved this problem. Nearly 100 years ago, the first built-in car GPS was released – and this is an innovation that is still an important part of car design. Planning the user interface is a very exciting issue, because only in a few seconds the display needs to provide the user with the right amount of information. In this research our goal was to assess Hungarians driving and built-in GPS using habits and based on this try to suggest the “perfect” interface. A questionnaire was made with 19 or 46 questions and more than 1000 respondents completed it. Because of the high number of questions only selected diagrams are represented. Some answers have also been subjected to different statistical tests.

Authors: Yürükçü Aytaç
Published: July 2019

Abstract. Many literary or scientific works had reached immortality by either its content or the author. Without a shadow of a doubt, Pîrî Reis' major work, a navigation book titled Kitab-ı Bahriye is one of those works that are passed down from generation to generation, light the way of historical process with the intense knowledge it contains, and guide researches and navigators. In Kitab-ı Bahriye which was written as a guide for navigators, sea towns are plotted in maps, bays are denoted, and information about ports for ships to berth, shoals, castles and habitants of these places are given. Furthermore, this work, as a reference book, has a very important place for geographical discoveries where experiences and fund of scientific knowledge accumulated for ages were verified and transmitted through generations in great detail. Kitab-ı Bahriye and world map of Pîrî Reis dated 1513 is not only a source for discoveries, navigation, cartography and cartography works but also it contains important and valuable data about word history and experiences, myths, values and historical positions of societies in 16th century. So much so that information in the book is ranging from Aegean and Red Sea to China Sea, from Indian Ocean to Japanese Sea.In this article, it will be focused on how Pîrî Reis plotted such a precious map in that ages, from which books and works he got inspired while working on it, in which coasts he made observations and how he used these observations on his world map of 1513 and his unique work called Kitab-ı Bahriye. Being able to be studied by researchers after centuries, these two precious works also draw attention to how this kind of documents can be protected carefully for long duration in archives and museums. Lastly, with the examination of maps and drawings that have a past of 506 years, it is aimed at to understand mind world and all works of famous scientist Pîrî Reis who was commemorated by UNESCO in 2013 better and to share his impressions about new world geography in detail with researchers.
