Authors: Yuen Joseph S.M. , Choy K.L. , Lam H.Y. , Tsang Y.P.
Published: July 2018

A comprehensive outbound logistics strategy of environmentally-sensitive products is essential to facilitate effective resource allocation, reliable quality control, and a high customer satisfaction in a supply chain. In this article, an intelligent knowledge management system, namely the Internet-of-Things (IoT) Outbound Logistics Knowledge Management System (IOLMS) is designed to monitor environmentally-sensitive products, and to predict the quality of goods. The system integrates IoT sensors, case-based reasoning (CBR) and fuzzy logic for real-time environmental and product monitoring, outbound logistics strategy formulation and quality change prediction, respectively. By studying the relationship between environmental factors and the quality of goods, different adjustments or strategies of outbound logistics can be developed in order to maintain high quality of goods. Through a pilot study in a high-quality headset manufacturing company, the results show that the IOLMS helps to increase operation efficiency, reduce the planning time, and enhance customer satisfaction.
Social Network Analysis Based on Topic Model with Temporal Factor
Authors: Ho Thanh , Do Phuc
Published: July 2018

On social networks, each message has many features where the interested topics and the actors sending and receiving topics are important features. Unlike the traditional approach, which views each message belonging to a topic, the topic model is based on the approach, which indicates that each message has a mixture of many topics. However, topic model has limitations about discovering interested topics of actors with temporal factor and labelling latent topics. The article proposes a temporal-author-recipient-topic (TART) model based on: (i) discovering interested topics and analyzing the role of actors on social networks with the temporal factor; (ii) labelling the latent topics from topic model based on topic taxonomy; (iii) applying the temporal factor for finding the relation among factors in model; and (iv) finding out the variation of interested topics of actors with each period of time. An experimenting TART model on two corpora with 1,004,396 messages in Vietnamese and 25,009 actors by the software is built for SNA.

Published: July 2018

This article aims to analyze corporate social responsibility (CSR) communication in today's health care systems. The authors investigate the importance of CSR communication and the use of both traditional and interactive technologies for healthcare CSR communication, adopting quantitative research methodologies. In order to understand different applications of the topic, the article examines and compares best practices regarding CSR communication between two extremely different countries and contexts: namely Malta and India. Results emphasize a growing attention on healthcare CSR communication in both countries. The key finding observed is that healthcare organizations are using a mixed strategy to communicate their CSR activities. Indeed, interactive technologies enable several advantages to organizations than traditional tools (such as better dialogue and interaction with different stakeholders, speed, low costs, easy access to information), as well as they require investments and costs in infrastructures and skills/competencies for their implementation.

Authors: Raguseo Elisabetta , Pigni Federico , Piccoli Gabriele
Published: July 2018

This article describes how in their search for value creation, companies are investing considerable resources in so-called “Big Data” initiatives. A peculiar aspect of these initiatives is the increasing availability of real-time streams of data. Successfully leveraging these streams to extract value is emerging as a critical competence for the modern firm. Despite the significant attention received, scholarly research on Digital Data Stream (DDS) remains insufficient. More importantly, there are no specialized definitions and measurement instruments that can move the field forward by initiating a cumulative research tradition. This article can provide clarification on key definitions, differentiating DDS from Big Data. Drawing on the organizational readiness concept, the DDS readiness index develops as a measure of organizational readiness to exploit real-time digital data. This article will conceptualize, define, operationalize and validate the index. By identifying the four dimensions of mindset, skillset, dataset and toolset as the elements of the DDS readiness index and discussing its managerial and research implications
Smart Agricultural Enterprise System Based on Integration of Internet of Things and Agent Technology
Authors: Kitouni Ilham , Benmerzoug Djamel , Lezzar Fouzi
Published: July 2018

This article describes how the Internet of Things (IoT) and its smart objects will be the fundamental building blocks for the creation of smart pervasive systems. Precision Agriculture can be defined as the use of information, communications technologies and electronic devices in agricultural practice, to improve agricultural production. This article addresses the problem of modelling Precision Agriculture systems. The authors propose an Agent-based approach for an effective integration of the IoT technology in Agricultural Enterprise systems. The proposed approach is based on Agent Interaction Protocols (AiP) through which they specify complex services of the system by recognizing larger chunks that have a meaning in the application domain. The AiP supports the modelling of composite services as entities whose business logic involves a number of interactions among more elementary service components. The authors present an agent-based system architecture whose main goal is to address interoperability issues between heterogeneous IoT-based services by offering a harmonized API.
The First Decade of Web-Based Sports Injury Surveillance (2004–2005 Through 2013–2014): Methods of the National Collegiate Athletic Association Injury Surveillance Program and High School Reporting Information Online
Authors: Kerr Zachary Y. , Comstock R. Dawn , Dompier Thomas P. , Marshall Stephen W.
Published: July 2018

Objective: 

To describe the methods of the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP) and High School Reporting Information Online (HS RIO) system as a complement to the sport-specific manuscripts that will follow.

Background: 

The NCAA-ISP and HS RIO collect injury and exposure data from samples of collegiate and high school sports programs, respectively. The NCAA-ISP, which the NCAA has maintained since 1982, was relaunched as a Web-based platform at the beginning of the 2004–2005 academic year. In 2005, the HS RIO was introduced to capture data on high school athletes and modeled after the NCAA-ISP. Relevant data are shared with the NCAA and high school sport and policy committees to develop evidence-based rules and programs that help protect the health and safety of student-athletes.

Description: 

The NCAA-ISP and HS RIO monitor participation in school-sanctioned competitions and practices that occur from the first preseason practice to the final postseason contest for more than 25 sports. For this series of publications in the Journal of Athletic Training, injury information on 13 sports at the collegiate level during the 2004–2005 through 2013–2014 academic years and the high school level during the 2005–2006 through 2013–2014 academic years was evaluated.

Conclusions: 

Athletic trainers have been a vital source of data collection over the past decade to help produce the largest datasets of collegiate and high school sports injuries. Such data have helped various sport and policy committees advance protocols that aim to increase sports safety. This series of publications will aid by continuing to provide data to stakeholders in the sports community.
Psychological sequelae of political imprisonment, specifically post-traumatic stress disorder, in 491 Days by Winnie Madikizela-Mandela
Authors: Botha Marisa
Published: July 2018

This article analyses well-known anti-apartheid activist Winnie Madikizela-Mandela’s prison memoir 491 Days: Prisoner Number 1323/69 (2013) for depictions of suffering. This memoir reveals aspects of politically inflicted trauma, particularly the suffering sustained in prolonged solitary confinement and the resulting psychological sequelae for the prisoner. To move beyond a vague understanding of her traumatic experiences, this article draws on the field of psychiatry, specifically the diagnostic criteria for post-traumatic stress disorder (PTSD) to gain greater insight as this tool may also be regarded as a type of narrative that could aid in the comprehension of traumatic events. References will be made to the three main cluster symptoms of PTSD: involuntary re-experiencing of the traumatic event, avoidance of reminders and an ongoing sense of threat. An interdisciplinary literary-psychological approach will probably lead to a deeper understanding of the mental consequences of political imprisonment, as PTSD was not an acknowledged disorder during Madikizela-Mandela’s detainment.
Intraosseous lipoma of the maxillary tuberosity
Authors: Babu Sharlene Sara , Sunil S. , Pratap Nithin , Thomas Eapen
Published: July 2018

Lipoma is called the “universal tumor” or the “ubiquitous tumor” as it occurs anywhere in the body where fat is found. Intraosseous lipoma is a rare lesion that constitutes not more than 0.1% of bone tumors. There are only a few reported cases of intraosseous lipoma of the maxilla in the literature. The diagnosis of intraosseous lipoma of the maxilla may be a challenge, due to its rarity and clinical similarity with many other radiolucent lesions. Therefore, histopathological examination is mandatory. The radiolucent nature and mature adipose tissue admixed with the bony trabeculae confirms the diagnosis of intraosseous lipoma. Here, we report a case of intraosseous lipoma of the left maxillary tuberosity in a 52-year-old male patient.

Published: July 2018

Aim of Study:

Metabolic syndrome (MetS) is an abnormality that increases the risk of cardiovascular disease and diabetes. In the recent years, studies showed that MetS is associated with increased risk of incidence, aggressiveness, and mortality of prostate cancer (PCa). We examined the influence of MetS at final pathology in Turkish patients with PCa.

Materials and Methods:

MetS was defined according to the American Heart Association, National Heart, Lung, Blood Institute, and International Diabetes Federation and requires any three of five components. The patients without and with MetS were in Group 1 and 2, respectively. Data were compared with independent sample t-test and Chi-squared test.

Results:

There were 117 patients in the study. The patients' age was between 51 and 77 years with a median of 64.87 ± 5.65 and 62.29 ± 5.57, and prostate-specific antigen (PSA) level of the patients was 8.19 ± 5.35 and 8.68 ± 2.22 ng/ml in Group 1 and 2. Of these patients; Group 1 and 2 had 86 and 31 patients. High-grade PCa (Gleason >7) and advanced PCa (T3, T4) at final pathology were reported in 44.18–18.60% and 38.70–32.25% in Group 1 and 2.

Conclusion:

The patients with MetS are diagnosed significantly younger and had higher PSA levels than the other patients. Advanced disease of PCa is seen much more in patients with MetS.

The Departing Body: Creation of the Neutral in-between Sensual Bodies
Authors: Innami Fusako
Published: July 2018

This paper investigates the Japanese concept of ma/aida, the space in-between, discussed by French author Roland Barthes as the Neutral, not signifying the medium of the opposite poles but the bare existence. It first analyzes how the discourse of contiguous relationships and the space between others has functioned in modern and postwar Japan, and further employs the works of the Japanese female writer Matsuura Rieko as counterexamples,with particular emphasis on the space between the sensual and the sexual. It provides a fresh view on the conceptions of space and indirectness between and within the body.
Contemporary Japanese Literature in Its Transition Towards the New Postmodern Humanism: Haruki Murakami
Authors: Frentiu Rodica
Published: July 2018

Although Japan recorded no specific literary movement in the 1980s, in any classical sense of the term, we may say that today we are witnessing, in terms of our historical sensibility, a condensation of narrative viewpoints upon the present or, in other words, the transposition of the criteria of the present to another time, which is undoubtedly a consequence of the so-called “postmodern” will to reject grand narratives. This study aims to review and complete the inventory of the postmodern characteristics that specialisedliterature has identified in Haruki Murakami’s works, seen from the perspective of what the author of the present paper considers to be the “new postmodern humanism.”
Contextualizing the Centennial of Japanese Colonial Rule in Korea
Authors: Kingston Jeff
Published: July 2018

This article examines the 2010 commemoration of the centennial of Japanese colonialism in Korea. Prime Minister Kan Naoto’s apology generated controversy, exposing the longstanding domestic divide within Japan over the imperial past. The politicization of history, apologies and acts of contrition impedes reconciliation between Japan and its Asian neighbours. Apologies and acts of contrition may not be sufficient to advance reconciliation, but remain essential elements of that process. Japan’s legalistic position based on the 1965 Basic Treaty may protect it from further compensation claims, but also precludes the grand gestures that are essential to reconciliation.

Who is The Refugee by the Cradle? Some Thoughts about the Song by Anton Lajovic
Authors: Šter Katarina
Published: July 2018

The present article opens some new questions about Begunka pri zibeli [The Refugee by the Cradle], one of Anton Lajovic’s best and most expressive songs for voice and piano, which was also connected with the historical events by the Soča/Isonzo front in the First World War. Special attention is given to the original literary text by Oton Župančič. His allusions to the painting of the Virgin Mary from the place of pilgrimage Sveta gora near Gorica/Gorizia, which also shared the refugee’s fate, could bring new insights into the identity of the “refugee by the cradle”.
From Myth to Reality: Stevan Stojanović Mokranjac and Serbian Church Music
Authors: Peno Vesna , Vesić Ivana
Published: July 2018

In this paper, we will focus on the historical reconstruction of Stevan Stojanović Mokranjac’s work in the field of melography and pedagogy of Serbian church chant. Since the prestigious status he reached among his contemporaries, as well as musicologists and music historians of the recent past, both as a melographer and expert in Serbian church chant of his time, has rarely been questioned or objectively approached, we decided to reconsider some of the dominant interpretations of his activities in this domain. For that purpose, we conducted a thorough research of archival resources and press material from the late 19th century onward aiming at a critical examination of Mokranjac’s role in the popularization of concepts of the Karlovac and Belgrade church chant styles, his undertakings in the documentation of monophonic church chants, and, finally, his approach to the teaching of chant singing in Saint Sava’s Seminary. We will underline the discrepancy between the created image of Mokranjac as an indisputable authority in the field and historical data, which point to the significance of his symbolic (and social) capital in the process of gaining broader recognition.

Robustness of Prefabricated Prefinished Volumetric Construction (PPVC) High-rise Building
Authors: Chua Yie Sue , Liew Jat Yuen Richard , Pang Sze Dai
Published: July 2018

Due to the safety awareness arisen from natural and human-caused disasters, robustness design of building is increasingly important to ensure the stability of the building and to prevent progressive collapse. For this reason, the robustness design of innovative construction technologies such as modular construction may be essential due to its relative novel structural form and numerous joints among modules. Particularly in Singapore, Prefabricated Prefinished Volumetric Construction (PPVC) has been highly promoted in residential and commercial buildings, hostels and hospitals to boost the construction productivity and quality as well as to reduce the reliance on foreign workforce. PPVC offers high quality and efficiency because most of the finishes and mechanical and electrical services are manufactured and installed together with the modules in factory, before sending for on-site assembly. To maximize the productivity of PPVC, modular design standardization and repetition can be improved by going for high-rise. Nonetheless, there are limited studies on the robustness of PPVC high-rise building and its behavior under progressive collapse remains uncertain. Therefore, this paper investigates the robustness of steel PPVC high-rise building under column removal scenarios by conducting non-linear numerical analysis. The effects of joint design and diaphragm action between modules are studied to ensure continuity of horizontal and vertical tying. This paper provides insight on the behaviour and alternative path for load transfer under column removal scenario for future design guideline of robustness PPVC building.

Published: July 2018

To combat the present situation of greenhouse gases emission from cement production, a promising solution is to utilise supplementary cementitious by-product materials such as fly ash to produce green concrete known as Geopolymer concrete (GPC). However, despite fly ash based concrete is a promising substitute for ordinary Portland cement (OPC) concrete, it is not yet being utilised to its full potential for structural applications.  And so, to utilise green concrete to its full potential, this paper aim is to conduct an experimental study that will integrate fly ash based concrete within steel-concrete composite beams. The research will include casting of composite beams with GPC mix, and an OPC concrete as a reference mix designed according to British Standards. To determine the ultimate moment capacity, a total of Four (4) composite beams comprised of coventional and Bondek steel profile concrete slab are designed and tested according to Australian Standards. From the test results, it was found that composite beam with conventionalconcrete slab outperformed the beams with Bondek profile sheeting. Also, regarding of ultimate bending moment capacity, the composite beam with geopolymer concrete experienced almost identical to OPC composite beam.
Material tests of 316L austenitic stainless-clad steel at elevated temperatures
Authors: Ban Huiyong , Bai Risheng , Chung Kwok-Fai , Bai Yin
Published: July 2018

Mechanical properties of stainless-clad (SC) steel plates at elevated temperatures are key parameters for fire resistant design and numerical simulation analysis of SC steel structures. Compared with pure stainless steel and pure ordinary steel, SC steel not only combines advantages of the two component metals, but may also balance the performance and cost; however, it behaves quite differently in terms of material properties. In order to quantify this performance, tension coupon tests at room as well as elevated temperatures are conducted on the SC steel plate. Based on the test results, failure modes of the tension coupons are analysed, and full-range stress-strain curves are obtained; material properties are accordingly determined and described herein, and analyses are performed on several properties including yield strength, ultimate tensile stress, elastic modulus and elongation after fracture. It is found that with an increase of the temperature, both the elastic modulus and strengths are reduced remarkably. For determining these material properties quantitatively and developing robust constitutive models of the SC steel at elevated temperatures, more test data are needed, and the incorporation of the  effects of the clad ratio on the material properties at both room and elevated temperatures is also necessary. The present research outcomes may provide valuable reference for fire design and calculations of the SC steel.
A novel one-sided push-out test for shear connectors in composite beams
Authors: Al-Shuwaili Mohammed Abdulhussein , Palmeri Alessandro , Lombardo Maria Teresa
Published: July 2018

Push-out tests (POTs) have been widely exploited as an alternative to the more expensive full-scale bending tests to characterize the behaviour of shear connections in steel-concrete composite beams. In these tests, two concrete slabs are typically attached to a steel section with the connectors under investigation, which are then subjected to direct shear. The results allow quantifying the relationship between applied load and displacements at the steel-concrete interface. Since this relationship is highly influenced by the boundary conditions of POT samples, different experimental setups have been used, where the slabs are either restricted or free to slide horizontally, as researchers have tried to reduce any discrepancy between POT and full-scale composite beam testing. Based on a critical review of various POT configurations presented in the dedicated literature, this paper presents an efficient one-sided POT (OSPOT) method. While OSPOT and POT specimens are similar, in the proposed OPSPOT setup only one of the two slabs is directly loaded in each test, and the slab is free to move vertically. Thus, two results can be obtained from one specimen, i.e. one from each slab. A series of POTs and OSPOTs have been conducted to investigate the behaviour and the shear resistance of headed stud connectors through the two methods of testing. The results of this study than were compared with those of different POTs setups conducted by other researchers. The new OSPOT results show in general an excellent agreement with the analytical predictions offered by both British and European standards, as well as the estimated shear resistance proposed other researchers in the literature. These findings suggest that the proposed one-sided setup could be used as an efficient and economical option for conducting the POT, as it has the potential not only to double the number of results, but also to simplify the fabrication of the samples, which is important in any large experimental campaign, and to allow testing with limited capacity of the actuator.
Push-out tests on demountable shear connectors of steel-concrete composite structures
Authors: Kozma Andras , Odenbreit Chirstoph , Braun Matthias Volker , Veljkovic Milan , Nijgh Martin
Published: July 2018

The deconstruction of steel-concrete composite structures in buildings and the later separation of the materials is a labour- and cost intensive work. This is due to the fact, that the shear studs are welded on the steel beam, and a large amount of cutting work gets necessary. As a result, recycling is difficult and the potential for reusing entire elements is lost. The carbon footprint of composite structures could be decreased by the application of the principles of “design for deconstruction and reuse”. This paper presents a study with its respective laboratory experiments on demountable shear connectors that facilitate recyclability and even offer the potential for reusing elements in their entirety. In the Laboratory of Steel and Composite Structures of the University of Luxembourg 15 push-out tests have been carried out using different bolted connection systems suitable for multiple uses in order to verify their performance characteristics by means of shear strength, stiffness, slip capacity, ductility and ability of demounting. The investigated systems included pre-stressed and epoxy resin injection bolts, solid slabs and composite slabs with profiled decking. The results showed that the tested demountable shear connections could provide higher shear resistance than conventional shear connections in some cases. The connection failure happened in the bolts, while there was no or minor visible damage observed on the connected members. Most of the tested connections could fulfil the ductility requirement given by Eurocode 4. The application of epoxy resin in the hole clearance resulted in lower slip capacity. The outcome will provide an important basis for the calibration of the forthcoming enhancement and numerical simulation of the demountable shear connections. The failure behaviour, the observed damages and the resulting ability of the elements for later re-use are discussed in detail.
Influence of steel tube thickness and concrete strength on the axial capacity of stub CFST columns
Authors: Ibáñez Usach Carmen , Hernández-Figueirido David , Piquer Vicent Ana
Published: July 2018

In order to study the mechanical response of concrete-filled steel tubular (CFST) columns, several experimental and theoretical studies have been conducted in the last years. However, the influence of thin-walled steel tubes on the axial capacity of these composite columns is not completely stablished, especially when it is combined with high-strength concrete as infill. In this paper, the results of an experimental campaign on 9 concrete-filled steel tubular stub columns subjected to concentric load are presented. Different cross-section shapes are considered in this campaign, i.e. circular, square and rectangular. The influence of the steel tube wall thickness is analysed by including in the tests specimens with thin-walled tubes, whose behaviour needs to be studied in depth given the issues arising when working under compression. The experimental program is designed so the analysis of the results permits to drawn consistent conclusions. For each series, the steel tube thickness is the only geometric parameter modified in order to properly study its effect. Besides, two different concrete strengths were considered for the concrete infill, i.e. normal and high- strength concrete, to observe their effect on the ultimate capacity of the columns. During the tests, the specimens are subjected to axial load and the evolution of the axial displacement with the load is registered. The ultimate capacity of each specimen is obtained and an analysis of the steel tube thickness and concrete strength influence is accomplished. Finally, the study of the dependency of the failure mode on these parameters is carried out.
How to sort out uncategorisable documents for interpretive social science? On limits of currently employed text mining techniques
Authors: Philipps Axel
Published: July 2018

Current text mining applications statistically work on the basis of linguistic models and theories and certain parameter settings. This enables researchers to classify, group and rank a large textual corpus – a useful feature for scholars who study all forms of written text. However, these underlying conditions differ in respect to the way how interpretively-oriented social scientists approach textual data. They aim to understand the meaning of text by heuristically using known categorisations, concepts and other formal methods. More importantly, they are primarily interested in documents that are incomprehensible with our current knowledge because these  documents offer a chance to formulate new empirically-grounded typifications, hypotheses, and theories. In this paper, therefore, I propose for a text mining technique with different aims and procedures. It includes a shift away from methods of grouping and clustering the whole text corpus to a process that sorts out uncategorisable documents. Such an approach will be demonstrated using a simple example. While more elaborate text mining techniques might become tools for more complex tasks, the given example just presents the essence of a possible working principle. As such, it supports social inquiries that search for and examine unfamiliar patterns and regularities.

Published: July 2018

This article provides a retrospective and understanding of the development of automatic learning methods. The beginnings are visualized as a discipline within Computer Sciences in the subcategory of Artificial Intelligence, its development and the current transfer of knowledge to other areas of Engineering and its industrial applications. Based on the publications about machine learning and its application contained in the Web of Science database, records from 1986 to 2017 are downloaded. After a description of the technological profile, a new approach is introduced to the classification of a discipline based on the year of appearance of those terms that define it. Mining of technological texts and network theory has been applied to extract the terms and interpret their evolution. They are the those that define the stages of emergence, development and maturation of the discipline Machine learning. The novelty of this approach lies in the technical nature of applied research in Machine Learning, which aims to be a guide for the development of future engineering applications and to make technology transfer toindustry visible.

Being there? A Collaborative Inquiry into Attendance
Authors: Menendez Alvarez-Hevia David , Lord Janet , Naylor Steven
Published: July 2018

There is a growing concern among universities over the levels of student absenteeism at teaching activities. Attendance is an increasingly important issue in the UK, but also internationally, for its impact on the student experience, academic performance and engagement.  This article explores the topic of poor attendance in one of the larger universities in the UK, through a collaborative action research methodology that includes Education Studies lecturers and students as research partners.  Initial findings suggest that attendance is conceptualised in different ways by different actors. We found that a key theme in understanding attendance and engagement was that students’ identities are multi-layered and complex, and that their identities as students are often interwoven. We also found that technology and the virtual world play a fundamental role in understanding practices and conceptualising attendance and engagement. Concerning this, the way that a Virtual Learning Environments is approached in our study illustrates how physical attendance is challenged (but also supported)  as a privileged form of getting access to the knowledge presented in taught sessions.

The paper describes an innovative teaching experience held at the Faculty of Architecture the University of San Carlos of Guatemala as part of the  Professional Practice Program (EPS). 20 students and 9 professors, coordinated by 4 professors, carried out a workshop on the theme of Healthy City (HC) in the Municipality of Mixco, with the support of the same. Through active learning, a ‘deprivatization’ of the teaching activity and a participatory confrontation activity through interviews and questionnaires with citizens and stakeholders, the students and professors worked in 4 groups for seven days creating a community of practice. The results took the form of project proposals aimed at urban regeneration, in accordance with the principles of the HC, presented to the local community and to the Municipality of Mixco. The experience can be repeated in its methodology and has been positively evaluated by all the participants in terms of: acquisition of competences for dialogue with citizens and stakeholders for the identification of needs, increase in design skills and group work, as well as real service in the territory. The future urban planners and architects have also played a new role as mediators of participatory processes and facilitators.

Many students have feelings of state anxiety when exams, and these feelings probably affect their performance. Statistics courses have been identified as producing the most anxiety. The purpose of our study is to measure statistics anxiety throughout an academic course (pre-test and three assessments) in order to observe its change and analyze the relationship between statistics anxiety and academic achievement. The sample is composed of 30 Psychology students taking a course in research designs and statistics (26.7% men and 73.3% women) with a mean age of 20.31 years (SD = 3.76). The results show that the students begin with a high level of statistics anxiety that gradually declines as the course progresses and they study the course materials. Moreover, the final achievement in the subject maintains an inverse relationship with the level of statostics anxiety. The recommendation is to present the detailed contents of the teaching guide on the first day of the course in order to reduce students' anxiety and uncertainty when beginning a statistics course.

The search for increasing the effectiveness of training leads to the use of innovative technologies, which include gaming. The purpose of this article was to identify the extent and nature of the introduction of gaming methods in the educational process of the Russian State Social University. The paper used a comparative analysis of students and teachers assessment of management training using the gaming of the educational process. The empirical basis was the results of a sociological survey conducted using the Google Forms online service. 48 teachers and 178 students took part in the sociological survey. As a result, it was possible to establish that the introduction of gaming in the university is controversial. Despite the understanding of the usefulness of gaming by university employees, only 29% of teachers constantly use gaming methods. Students are dissatisfied with this, noting that gaming techniques are either fragmented (54%) or not used at all (37%). Students with a desire to participate in classes with gaming methods, especially in an integrated business game. Achievement of students' success at the class increases their social status. The study showed that the potential for gaming is not fully used.
Learning in the Era of Online Videos: How to Improve Teachers’ Competencies of Producing Educational Videos
Authors: Kauppinen Tomi , Guseva Yulia
Published: July 2018

Online videos have gained huge popularity among people seeking for entertainment, and increasingly also among learners. People seek for tips in videos, ranging widely from improving language skills to bike reparation, or from solving mathematical equations to indoor decoration. At the same time teachers are facing challenges of producing professional videos that can support learners to learn the variety of topics. Teachers at the higher education institutes are often professionals in presentation skills in classrooms, but can face challenges when presenting in videos. In this paper we present a process for improving skills needed to produce educational videos. The process starts from the assumption of often explicit question by the teacher: “How can I produce professional educational videos?” The process includes identifying main challenges teachers face, and continues with a series of hands-on workshops targeted to develop each of the skills followed by the video production itself. We report also an evaluation of the process with teachers from the Aalto University, discuss the implications and resulting categorization of production models.
Clinically relevant medicine label-based exercises: a friendly bridge between medicinal chemistry and pharmacotherapeutics
Authors: Giorgi Giorgio , Bravo Llatas María del Carmen
Published: July 2018

Aims. To make the students of Medicinal Chemistry (MC) course for doctor of pharmacy (PharmD) understand how strongly connected the chemical properties of drugs are to their clinical profiles and therapeutics, and determine students’ satisfaction degree. Design. Students in the spring 2013 section of the MC course were taught in a traditional teacher-centered manner. Students in the spring 2015 and 2016 ones had additional guided clinically relevant medicine label-based exercises. They worked in structured self-selected teams and chemically explained the clinical aspects of the selected drugs during oral communication sessions. They were given a 1 to 4 Likert-type scale satisfaction questionnaire, the data were collected and statistically treated. Results. The project was useful to show the connection between the chemical aspects of drugs and their clinical profiles (mean=3.33±0.65) and globally satisfactory (mean=3.07±0.47). The additional didactic material helped the students in the spring 2016 make the most of the MC course (mean=3.38±0.74, p=0.002). Conclusions. Medicine label-based exercises seem to be helpful to understand the connection between medicinal chemistry and pharmacotherapeutics. Feedback from students is generally quite favourable. The approach taken will continue to be modified and expanded.
Information from Automated Evaluation in an Engineering School

Published: July 2018

The paper introduces the need for automated evaluation and presents the experience of automating all the evaluations of a course in Computer Science in the sophomore year of an engineering degree. First, the paper describes the features needed and developed for that course and the positive results for both professors and students. The main advantage of automated evaluation is that it allows real continuous grading for all types of activities: short answers and exercises during the class, homework, short exercises evaluated every 10 days in class, medium term evaluations and the final grade for the course. A significant benefit of this practice is that it allows the professor, from the very beginning of the course, to monitor how the students perform each task. The professor can see in real time the marks of an exercise or evaluation, the global evolution of the class or the status of a specific student. The students also have immediate feedback from their exercises and the total points obtained at any given time providing greater involvement in the course.
