Patient Alcohol Consumption and Knowledge of Safe Alcohol Use at Dr. George Mukhari Academic Hospital, Pretoria
Authors: Nashed Kamelia Kamel , Mabuza Langalibalele Honey 
Published: June 2019

Background:
According to the World Health Organisation (WHO), there were 3.3 million deaths globally due to alcohol use in 2012. Establishing patients’ knowledge of safe alcohol use and practices regarding alcohol consumption could reform intervention policies.

Objectives:
The aim of this study was to assess patients’ knowledge of safe alcohol use and practices regarding alcohol consumption among patients attending the Family Practice Clinic at Dr. George Mukhari Academic Hospital (DGMAH) in Pretoria.

Methods:
The sample consisted of 300 patients (150 males; 150 females). Data relating to patients’ baseline characteristics, knowledge of safe alcohol use and practice were collected by means of a researcher administered questionnaire. The SAS, Release 9.3 was used for data analysis. The statistical level of significance was set at p < 0.05.

Results:
Majority of the respondents had lack of knowledge on safe quantities of alcohol use per day, for male and female individuals [268 (89.3%) vs 32 (10.7%); p < 0.0001] and [279 (93.0%) vs 21 (7.0%); p < 0.0001], respectively. Respondents mostly consumed alcohol on special occasions (152; 50.7%), and on weekends (100; 33.3%). Age groups ≥ 38 years consumed more alcohol per day (100; 33.3%). Majority of the respondents (179; 59.7%) were binge drinkers. Relatively less patients with higher levels of education were chronic harmful users of alcohol (p ≤ 0.001).

Conclusion:
The finding that majority of the patients lacked knowledge on safe quantities of alcohol use for males and females, and the unsafe use of alcohol, including binge drinking, warrant introduction of safe alcohol use awareness campaigns at primary health care, particularly targeting the middle aged and the elderly.

Authors: Sheykhasadi Hakimeh , Abbaszadeh Abbas , Bonakdar Homira , Salmani Fatemeh , Tavan Asghar , Sedri Nadia 
Published: June 2019

Background:
One of the forms of ost-operative care after open heart surgery is controlling the pain resulting from chest tube insertion. Management of pain is considered vital and requires the awareness of health care providers. One of the main responsibilities of nurses is to prepare patients for invasive procedures such as the removal of the chest tube. This study was designed to analyze the impact of a loved one’s voice for distraction in patients undergoing open heart surgery.

Methods:
This study was a clinical trial. The research sample was randomly selected from patients undergoing open heart surgery. In this study, the number of samples for each group was considered to be 64 people, where the total number of samples was 128 people. The data collection tools included Visual Analog Scale (VAS) assessment tool and a researcher-made questionnaire. After selecting the eligible samples and obtaining the informed consent, each patient was randomly assigned to one of the two groups (intervention group and control group). The pain was measured before, immediately, and 10 minutes after removing the chest tube.

Results:
The findings of this study indicated that the two groups had no statistically significant differences in pain before chest tube removal. The mean pain during chest tube removal and 10 minutes later in both groups indicated a significant difference based on Mann-Whitney test (P<0.001).

Conclusion:
This study showed that a loved one’s voice is effective in reducing pain during chest tube removal after open heart surgery.
Nieuw musea in de stad: Tussen kunst en kitsch

Published: June 2019

Veel steden hebben de laatste jaren geïnvesteerd in nieuwe of de uitbreiding van bestaande musea. De vraag dringt zich op welke motieven ten grondslag liggen aan de recente museumgolf. Zijn kunstinhoudelijke argumenten doorslaggevend of spelen plaatspromotie en stedelijk imago een belangrijke rol?
Extraction from Moist Snuff with Artificial Saliva of Benzo[a]pyrene and Other Polycyclic Aromatic Hydrocarbons
Authors: Moldoveanu Serban C. , Marshall Jerry W. , Poole Thomas H. 
Published: June 2019

Summary
The present study evaluated in vitro extractability of various polycyclic aromatic hydrocarbons (PAHs) from moist snuff, when the extracting agent was water or artificial saliva. The extraction was performed on nine brands of moist snuff samples that are commercially available and were purchased from the market in January 2018. The moist snuff brands were selected to represent brands with different tobacco cut size descriptors and flavors. For the measurement of PAHs, two different analytical methods were used, an HPLC (High Performance Liquid Chromatography) method for measuring only benzo[a]pyrene (BaP) and a GC/MS/MS (Gas Chromatography Tandem Mass Spectrometry) method for measuring 21 PAHs (including BaP). These methods were modifications of preexistent methods reported in the literature. The results for BaP indicated that by extracting 500 mg of freeze-dried moist snuff with 6 portions of 20 mL water (120 mL), or with 4 portions of 20 mL artificial saliva, followed by two portions of 20 mL water, the BaP remains close to 100% in the solid material and it is not detected in the extracting solution. PAHs with a molecular weight similar or heavier than BaP also showed no extractability. Lighter PAHs such as fluorene, phenanthrene, anthracene, and 5-methylanthracene showed a relatively good extractability. An intermediate group including fluoranthene, pyrene, and benz[a]anthracene showed some extractability in the conditions of this in vitro experiment. This study is not a substitute for clinical studies regarding PAH uptake in human users of moist snuff. However, the results indicate very limited bioavailability of BaP and heavier PAHs from moist snuff. Higher, but variable bioavailability was indicated for lighter PAHs. Important implications of these findings are that: 1) measurably different BaP content of two moist snuff products is unlikely to result in any meaningfully different consumer exposure to BaP; and 2) biomarkers for one PAH cannot necessarily be used as a reliable indicator of exposure to another PAH, particularly if the molecular weights of the precursor PAHs differ since their bioavailabilities can be very different.

Use of Interactive Whiteboard in Teaching Mathematics for Sustainability and its Effect on the Role of Teacher
Authors: Kutluca Tamer , Yalman Murat , Tum Ali 
Published: June 2019

Abstract
As interactive whiteboards have been used recently in secondary schools for sustainability, this study on use of interactive whiteboards is considered to be very important in terms of knowing the effects of interactive whiteboards on mathematics lessons, determining the perspectives of teachers as users of the system and increasing the efficiency of the attempts related to the use of interactive whiteboards. In this respect, the purpose of the study was to investigate the use of interactive whiteboard in teaching mathematics for sustainability and to examine its effects on the role of teachers. The qualitative research approach was adopted in the study as it tried to conduct a deep analysis of a situation. The study was conducted with eight secondary school mathematics teachers working in the province of Adiyaman in Turkey. The research data were collected using a semi-structured interview form developed by the researchers. Each interview lasted in a period of time ranging from 8 to 14 minutes. The data collected in the study were analyzed using descriptive analysis with a qualitative approach. In the study, the data were interpreted considering the following themes: “The changes created by interactive whiteboards in the process of teaching mathematics”, “The facilities provided by the system for mathematics teachers”, “The effects of using interactive whiteboards in teaching mathematics on the role of teachers”, “The preparations for using interactive whiteboards in teaching mathematics” and “Use of computer software with interactive whiteboards in teaching mathematics”. The results obtained in the study revealed that the teachers were not sufficiently informed or directed regarding the use of whiteboards in teaching mathematics or provided with in-service training support which they needed in relation to the use of interactive whiteboards especially in teaching mathematics. Current role of teachers existing in accordance with the constructivist educational approach has not changed with the use of interactive whiteboards in teaching mathematics, but this role has only become stronger. Furthermore, it was found that interactive whiteboards in mathematics classes are generally used for mathematical exercises.
Different approaches to the relationship of life & death (review of articles)
Authors: Gluchman Martin 
Published: June 2019

Abstract
The paper presents different approaches to the relationship of life and death among selected authors as a review of their articles within the last volume of the Ethics & Bioethics (in Central Europe) journal. The resource of the review is an article by Peter Singer The challenge of brain death for the sanctity of life ethics. Firstly, I try to analyze the issue when death occurs and when we can talk about death as a phenomenon that each and every living human being must come to terms within the course of their lives. Ethics of social consequences is used to analyze different approaches and states a conclusion defending the principles of humanity and human dignity within the scope of this ethical theory applied to various problem cases. I strive to support the question of the quality of life through the paternalistic approach of physicians influenced by their humane and dignified understanding of their relationship towards the patients. Ethics of social consequences offers many solutions to the discussed issues throughout the reviewed articles.
International cooperation in research and development of Artificial Intelligence – publication and patent activity
Authors: Kučera Zdeněk , Vondrák Tomáš 
Published: June 2019

Abstract
Artificial Intelligence (AI) is one of the dynamically evolving research fields on the global scale. The world production of publication associated with the AI field increased by a third over the four-year period 2013–2017. Even less research intensive countries as Iran, Turkey, India and Indonesia appear to increase the share of the AI topics in their publication output. In the Czech Republic the fraction of publications in the AI field increased by approximately 10 % over this period. It makes the lowest increase within the EU/EEA. The field normalized citation index of the Czech publications in the year 2016 was above the world average but it is deeply below the top countries USA, United Kingdom, Switzerland, Singapore, and Norway.
The extent of international cooperation in AI is generally below the world average. The Czech Republic falls into the group of less cooperating countries. The countries exhibiting the highest growth in AI research are underrepresented in the Czech cooperation portfolio. The fraction of Czech publications in AI coauthored by foreign authors is lower than the national average. It indicates a lower international collaboration in comparison with other research fields. CR falls also in the group of countries less engaged in the international cooperation. The Czech international collaboration misses the countries exhibiting the most vigorous R&D in AI. The international collaboration adds to the quality of the research. The Czech publications originating from the international collaboration are cited above the country average for the AI field. It is even more significant in the collaboration with researchers from the top countries in the AI R&D.
The patent activity in the AI field has grown significantly in recent years. There is a marked increase of patent applications having inventors/applicants from more than one country. It indicates that the applied R&D in AI has a more international character in comparison with other technology fields. A high intensity of collaboration in the authorship of patent applications is within language and geographically neighbouring countries and with countries having a highly internationalized R&D system. Multinational corporations involved in international innovation networks contribute also to the international cooperation. ICT corporations like IBM, Google, or Microsoft which often employ foreign researchers have a dominant role in international cooperation.
The R&D of the Czech enterprises is relatively closed to the international cooperation. Domestic enterprises in AI use foreign employees in a small extent. The domestic enterprises even do not tap into the pool of intellectual property authored by the Czech researchers. The majority of patents with participation of Czech inventors is registered by foreign corporations.

Published: June 2019

Abstract

Purpose
To investigate the effectiveness of using node2vec on journal citation networks to represent journals as vectors for tasks such as clustering, science mapping, and journal diversity measure.

Design/methodology/approach
Node2vec is used in a journal citation network to generate journal vector representations.

Findings
1. Journals are clustered based on the node2vec trained vectors to form a science map. 2. The norm of the vector can be seen as an indicator of the diversity of journals. 3. Using node2vec trained journal vectors to determine the Rao-Stirling diversity measure leads to a better measure of diversity than that of direct citation vectors.

Research limitations
All analyses use citation data and only focus on the journal level.

Practical implications
Node2vec trained journal vectors embed rich information about journals, can be used to form a science map and may generate better values of journal diversity measures.

Originality/value
The effectiveness of node2vec in scientometric analysis is tested. Possible indicators for journal diversity measure are presented.

Published: June 2019

Abstract
Nigeria has been unable to develop a viable ship building industry over the years notwithstanding several efforts of government at achieving that. The study aimed to identify and determine the principal component constraints to ship building development in Nigeria. Adopting the theory of constraint approach, survey research design was used in which primary data were obtained from questionnaire responses from employees and management staff of shipyards in the ship building clusters in Lagos, Port-Harcourt and Warri. The data collected were analyzed using principal component factor analysis, analysis of variance and pie-chart. It was found that the principal component constraints to the development of the ship building sector in Nigeria include financial constraint with Eigen value of 31.23%, infrastructural constraint with Eigenvalue of 26.35% and poor skill and technical know-how with Eigen value of 16.23%. This implies that financial constraints, poor skill and lack of technical know-how and infrastructural constraints contribute a cumulative Eigen value of 74.259% and thus constitute the dominant constraints impeding the performance of ship yards, ship building and repair sector in Nigeria. Development of national ship building and dry-docking funding scheme, ship building research and training center among other things were recommended.
Social Media: Factor Influencing Personal Transport for Leisure
Authors: Zainul Mohammad , Zamrudi Zakky 
Published: June 2019

Abstract
This paper is trying to examine the effect of social media in the use of personal transport for leisure purposes. Youngster are frequently identified as being adventurous and highly mobile, even few researcher modes of transportation choices play in important role in enhancing and fulfilling their desired experiences. In this paper, we would like to know the role of social media in enhancing the personal transport desire in south-east Kalimantan. Social media role is measured by borrowing the theory of technology acceptance model by using two variables namely perceived ease of use and perceived usefulness. A quantitative method was used to measure the variable by using questionnaire given to 230 respondents given to university student near south-east Kalimantan. The gathered data is analyzed by using generalized structured component analysis. The finding in this research indicates that both perceived ease of use and perceived usefulness of social media could affect individual intention to use personal transport. However, the larger effect has reflected by perceived usefulness. This means that social media has been recognized as a good reference to stimulate leisure by using personal transport.

Authors: Aminu Alarudeen , Raifu Isiaka Akande 
Published: June 2019

Abstract
The study examines firm’s investment behaviour sensitivity to cash flow before, during and after the recent global financial crisis using the data of 28 firms listed on the Nigerian Stock Market during the period from 2001 to 2012. The contribution of the study to the existing literature rests on using financial crisis as basis for classifying firms as either financially constrained or unconstrained. Employing the panel data and instrumental variable estimation techniques, the study finds that firms’ investment behaviour sensitivity to cash flow was higher during the financial crisis than before or after the financial crisis. In other words, Nigerian firms were highly financially constrained during the last financial crisis.

Published: June 2019

Abstract
Social media today represent a global community of different nationalities - the size of China in terms of population, and social networking sites are online venues where users can create and post content. Social networks have also become one of the most popular ways for people to socialize, connect with friends and family, purchase items and gather relevant information about current and political topics and views. The most popular and biggest social network is Facebook and its influence in every pore of our society is evident, e.g. potential misuse of its user’s data in different purpose including manipulation in political purposes. This paper will also cover the findings of a survey conducted in Croatia and Serbia about the perception of social media and social networks as a source of gathering relevant information.

Published: June 2019

Research subject. In this work, we investigated the crystals of pyrite, one of the key gold-bearing minerals, from the Berezovskoe (the Middle Urals) deposit using modern research approaches.Materials and methods. Samples for the analysis were collected from the ladder sulphide-quartz veins and related berezites in the Ilinskaya, Pervopavlovsk and Vtoropavlovsk dykes of the Berezovskoe deposit. The ores were studied using the methods of optical microscopy, X-ray microanalysis (PCMA), scanning electron microscopy (SEM) and LA-ICP-MS. The latter method was largely used to examine pyrite. Along with pyrite, the materials under study included faded ore, galena, and such rare occurring minerals as aikinite, cosalite, tetradymite and tsumoite. Results. According to the point and profile analysis, as well as grain mapping, the main impurity elements in the stu died samples are found to be Co, Ni and As. The distribution of these elements has shown a zonal character: the amounts of Co and Ni tend to increase and that of As tends to decrease towards the grain centre. In the pyrite samples, Cu, Zn and Pb occur either in the form of their sulphide micro-inclusions or as evenly distributed admixtures. The pyritic ore of later genera tions in the Pervopavlovsk dyke is established to contain gold in amounts of up to 22 g/t, with Au being zonally distributed. The goldbearing variety of pyrite is characterized by abnormally low contents of Co and Ni, as well as by an increased content of As (up to 8000 g/t). Conclusion. A common character of the distribution of main impurity elements in the pyritic ores in the studied dikes indicates similar conditions of their crystallization. The presence of late-generation pyrite with fine gold in the Pervopavlovsk dike evidences to a heterogeneous distribution of gold mineralization therein, likely due to the multistage character of the latter. This may also be an indicator of the concentration of ore columns, which fact requires further elucidation.

Published: June 2019

Carcinoma ex-pleomorphic nonmalignant tumour (Ca ex PA, CXPA) is a rare, aggressive, poorly understood malignancy of the exocrine gland. The clinical findings typical of this neoplasm embrace history of a slow growing, ulcerated, painless mass that enlarges speedily. The current definition of Ca ex PA became widely accepted in the second half of the twentieth century. It is uncommon, having a prevalence rate of 5.6 cases per 100,000 malignant neoplasms and a yearly incidence rate of 0.17 tumours per 1 million persons in the world. The cancer is found predominantly in the sixth to eighth decades of life and is slight female predilection.
