Low Redundancy Feature Selection of Short Term Solar Irradiance Prediction Using Conditional Mutual Information and Gauss Process Regression
Authors: Huang Nantian , Li Ruiqing , Lin Lin , Yu Zhiyong , Cai Guowei
Published: August 2018

Solar irradiation is influenced by many meteorological features, which results in a complex structure meaning its prediction has low efficiency and accuracy. The existing prediction methods are focused on analyzing the correlation between features and irradiation to reduce model complexity but they do not account for redundant analysis in feature subset. In order to reduce the information redundancy in the feature set and improve prediction accuracy, a novel feature selection method for short-term irradiation prediction based on Conditional Mutual Information (CMI) and Gaussian Process Regression (GPR) is proposed. Firstly, the CMI values of different features are calculated to evaluate correlation and redundant information between features in the feature subsets. Secondly, GPR with a stable prediction performance and adaptively determined hyper parameters is used as the predictor. The optimal feature subset and the GPR covariance function can be selected using Sequential Forward Selection (SFS). Finally, an optimal predictor is determined by the minimum prediction error and the prediction of solar irradiation is carried out by the determined predictor. The experimental results show that CMI-GPRAEK has the highest prediction accuracy with the optimal feature set has low dimension, which is 4.33% lower in MAPE than the predictor without feature selection, although both of them have an optimal kernel function. The CMI-GPRAEK is less complicated for the predictor and there is less redundancy between features in the model with the dimension of the optimal feature set is only 14.

Published: August 2018

Sensor devices that can be fabricated on a flexible plastic film produced at a low cost using inkjet-printing technology are suitable for point-of-care applications. An organic field-effect transistor (OFET)-based biosensor can function as a potentiometric electrochemical sensor. To investigate the usefulness of an OFET-based biosensor, we demonstrated the detection of 1,5-anhydroglucitol (1,5-AG) and glucose, which are monosaccharides used as biomarkers of diabetes. An OFET-based biosensor combined with a Prussian blue (PB) electrode, modified with glucose oxidase (GOx) or pyranose oxidase (POx), was utilized for the detection of the monosaccharides. When the GOx- or POx-PB electrode was immersed in glucose solution at the determined concentration, shifts in the low-voltage direction of transfer characteristic curves of the OFET were observed to be dependent on the glucose concentrations in the range of 0–10 mM. For 1,5-AG, the curve shifts were observed only with the POx-PB electrode. Detection of glucose and 1,5-AG was achieved in a substrate-specific manner of the enzymes on the printed OFET-biosensor. Although further improvements are required in the detection concentration range, the plastic-filmOFET-biosensors will enable the measurement of not only diabetes biomarkers but also various other biomarkers.

Published: August 2018

BACKGROUND: The composition of the root canal filling materials together with the apical limit of the root canal obturation affect the complete periapical healing after root canal therapy.AIM: This study was performed to evaluate and compare the periapical healing in response to calcium-silicate (iRoot SP) and calcium-hydroxide (Apexit) based-sealers.MATERIAL AND METHODS: Seventy-two upper premolars root canals of six dogs were used. The teeth were randomly assigned to four groups: Group one: roots were obturated using gutta-percha and Apexit-sealer; Group two: roots were obturated using gutta-percha&iRoot SP-sealer; Group three: the teeth were left open without obturation; Group four: where healthy teeth were used as a negative control. Teeth were evaluated after one, two and three months. The newly formed mineralised apical tissue and the periapical inflammatory infiltrate of the obtained photomicrographs were evaluated, and scorings were statistically-analysed.RESULTS: The mean percentage of the periapical inflammatory infiltrates and mineralisation scoring after one, two and three months evaluation period were not significantly different among the four groups (P > 0.05).CONCLUSIONS: Regardless of the sealer used, iRoot SP and Apexit promote healing of periapical tissues. IRoot SP sealer showed early insignificant more partial and almost full healing after two and three months.

Published: August 2018

BACKGROUND: Diabetes mellitus (DM), chronic disease, is a public health problem that affects 8.5% adult population worldwide. The number of adults with DM has risen sharply from 108 million in 1980 to 422 million in 2014. In 2012, 1.5 million individuals died because of DM and an additional 2.2 million deaths occurred because of high blood glucose level resulting in cardiovascular and other systemic diseases. DM brings huge economic loss to patients, their families, and healthcare systems. Globally, the cost of DM was US$1•31 trillion in 2015.AIM: This review article utilised the prevalence data of diabetes mellitus from the World Health Organization and International Diabetes Federation to provide a comprehensive picture of the disease in different parts of the world.METHODS: Electronic databases such as Google Scholar, Medline via PubMed, Scopus, and Web of Science were used to search the literature. The library resources of Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia were used to retrieve studies on the topics of the present review.RESULTS: Systemic complications of DM include heart attack, kidney disease, limb loss, blindness, and peripheral nerve damage. More than 90% of diabetic patients were found to have oral manifestations. It is known that DM severely damages oral tissues causing periodontal disease, tooth loss, xerostomia, caries, burning mouth disorder, taste and salivary gland dysfunction, delayed wound healing, lichen planus, geographic tongue, and candidiasis. The evidence is mounting about a strong bidirectional relationship between DM and periodontal disease. Unfortunately, many diabetic patients are unaware of the association between DM and oral health, and only a small percentage of them visit the dentist for routine dental check-ups. Changes in lifestyles (control of blood glucose levels and self-care practices), regular dental check-ups with emphasis on periodontal assessment, and reinforcement of oral health instructions can effectively prevent oral complications of DM. Scaling and root planning are effective in improving glycemic control among diabetic patients.CONCLUSION: Dental professionals should be part of the multidisciplinary team that helps individuals with diabetes.

Published: August 2018

BACKGROUND: Calcification of the arteries of the lower extremities is a very common pathological process, which has an independent significance in the development of cardiovascular diseases. There is evidence that development of calcification of the arteries correlates with a mutation of the MGP protein gene representing by the Thr83Ala polymorphism.AIM: The purpose of the study was to analyse the connection of Thr83Ala polymorphism of the MGP gene with the development of calcification of the arteries of the lower extremities.METHODS: The study involved 80 patients. Half of them had signs of calcification of the arteries of the lower extremities. The allelic Thr83Ala polymorphism of the MGP protein gene was determined by polymerase chain reaction, establishing the presence of calcification of the arteries by radiological and dopplerographic methods.RESULTS: The study aimed to analyse the association of the Thr83Ala polymorphism of the matrix Gla protein gene with the development of calcification of the arteries of the lower extremities. The data obtained suggest that the replacement of threonine by alanine in the 83rd position of the MGP molecule can affect the functional properties of the protein and in particular its anticarcinogenic properties. Although there was no difference in the distribution of different variants of the genotype by Thr83Ala to the MGP gene polymorphism in patients with CA and healthy patients, but in the distribution of genotypes in the comparison groups separated by sex, it was found that in women, carriage of the Ala allele in a homozygous state is a factor, which protects the development of arterial calcination in the elderly and senile.CONCLUSION: Differences in the distribution of different variants of the genotype according to Thr83Ala to the polymorphism of the MGP gene between patients with CAD and healthy patients do not exceed the limits of statistical significance. In the distribution of genotypes in the comparison groups divided by sex, it was found that in women the carrier of the Ala-allele in the homozygous state is a factor that prevents the development of Menkeberg arteriosclerosis in the elderly and old age.

Simulating Complex Supply Chain Relationships Using Copulas
Authors: Muralidhar Krishnamurty , Sarathy Rathindra
Published: August 2018

Simulation is often used as a tool to analyze and understand complex systems in supply chain management research. Supply chains involve complex relationships between different variables. Hence, it is necessary to simulate related non-normal distributions to simulate these systems. The simulation of related normal distributions is relatively easy and can be found in most simulation texts. However, when the marginal distributions under investigation do not have a normal distribution, it becomes very difficult to generate values from these related distributions. In this study, the authors illustrate a method based on copulas that allows for the generation of related distributions with arbitrary marginals. The procedure suggested in this study is simple and easy to implement. Using this procedure will enable researchers in supply chain management to more effectively simulate complex real-world scenarios resulting in better analysis and understanding of supply chains.

Published: August 2018

The prime purpose of the current study was to investigate the consequence of surfactant on the kinematic viscosity, thermal conductivity, and stability of MgO-oil based nanofluid. Magnesia (MgO) nanoparticles were prepared by the wet chemical method. Structural and morphological analysis of synthesized nanoparticles were performed via X-ray diffraction (XRD) and Transmission electron microscope (TEM). Subsequently, nanofluid was prepared at a solid concentration of 0.025% in presence of various surfactants with the aid of ultrasonic technique. The impact of the different surfactants (Cetyl Trimethyl Ammonium Bromide (CTAB), Poly Vinyl Pyrrolidone (PVP), Poly Vinyl Alcohol (PVA), and Oleic Acid) on the nanofluid stability was tested. It was evident that CTAB and PVA surfactants establish the most stable prepared MgO-oil based nanofluid. The experiments revealed that the maximum UV–Vis absorbance of the solution corresponds to the dispersion of CTAB in the base fluid.

Authors: Liman Muhammad Mukhtar , Abou-El-Hossein K. , Odedeyi Peter Babatunde
Published: August 2018

In this paper, Single point diamond turning tests were carried out on rigid gas permeable contact lens (ONSI-56), using monocrystalline diamond cutting tools. During the tests, the depth of cut, feed rate, and cutting speed were varied. Turning experiments were designed based on Box-Behnken statistical experimental design technique. An artificial neural network (ANN) and response surface (RS) model were developed to predict surface roughness on the contact lens turned part surface. In the development of predictive models, cutting parameters of cutting speed, depth of cut and feed rate were considered as model variables. The required data for predictive models are obtained by conducting a series of turning test and measuring the surface roughness data. Good agreement is observed between the predictive models results and the experimental measurements. The ANN and RSM models for ONSI-56 contact lens turned part surfaces are compared with each other for accuracy and computational cost.

Authors: Antil Parvesh , Singh Sarbjit , Manna Alakesh
Published: August 2018

The acceptability of polymer matrix composites for various industrial applications has been increased over the years due to their better mechanical properties. However, nonconductive nature and fibrous residuals produced during micro drilling of these materials has become major challenge for the research fraternity. The conventional machining of these materials causes high tool wear due to presence of abrasive particles. Recently, the electrochemical discharge machining (ECDM) process has emerged as potential contender for the machining of nonconductive hard and brittle materials. Keeping in mind all these challenges, the present research work focuses on micro drilling of PMCs using ECDM process. The experimentation was planned as per Taguchi’s methodology using L9 orthogonal array. Voltage, electrolyte concentration and duty factor were considered as process parameters whereas material removal rate and taper were observed as output quality characteristics. The regression equation and coefficients were obtained using regression analysis. Using this regression equations, further solutions were obtained by genetic algorithm.

Published: August 2018

Composite materials with aluminium alloy 8011 matrix and 0, 4 and 8 weight percentages of ZrB2reinforcements were synthesized by in-situ stir casting process. The presence and homogeneous distribution of the reinforcements were examined with X-ray diffraction analysis and scanning electron microscopic analysis. To investigate the effect of dry sliding wear parameters such as sliding distance, percentage reinforcement, load, sliding velocity and temperature on wear rate and co-efficient of friction, experiments were conducted using a pin on disc wear tester as per Taguchi’s orthogonal array design and the tribological behaviour of synthesized composites was investigated by statistical techniques. Significance and the influence of the parameters over the response were determined by analysis of variances and grey relational analysis was used to find the optimal combination of parameters to obtain minimum wear rate and co-efficient of friction.

Published: August 2018

The aim of this research was to determine the influence of the short carbon fibres in nylon PA6 polymer used for fused deposition modelling (additive manufacturing) technology. Specimens from pure PA6 and PA6 with short carbon fibres were fabricated, with both main directions of the material with respect to the build orientation in a 3D printer. Experimental tensile tests of the specimens were carried out at several temperatures according to ISO standards. The strength, tensile modulus and ductility in relation to the temperature were compared. A significant influence of the short carbon fibres on the strength and heat deflection temperature of the part was found in PA6 and also for the orientation of the build in the 3D printer.

Authors: Yao Zi Shan , Xu Guang , Zhou Ming Xing
Published: August 2018

Rebar steel is used in the construction of various buildings. Vanadium (V), one of microalloying elements, is often added in the rebar steel to improve mechanical property. In order to analyse the effect of V on the microstructure and property of rebar steel, 0.043 wt.% V was added in a 20MnSi rebar steel. The base steel and V added steel were refined in a 50 kg vacuum induction furnace and rolled to plates of 14 mm thick. The mechanical properties of two steels were compared by tensile tests on a Wan-10000 tensile testing machine. The microstructure and precipitation of two steels were analysed by SEM and TEM observations. The microstructures of two steels consist of ferrite and pearlite. However, the grains of V bearing steel are finer. Moreover, fine nanoscale precipitates of V can be observed in V bearing steel. Therefore, the mechanical property of V addition rebar steel is improved by gain refinement strengthening and precipitation strengthening.

Published: August 2018

Context: 

Annually, more than 1 million youth athletes in the United States receive or are suspected of receiving a concussion. The Balance Error Scoring System (BESS) is the most commonly used clinical balance evaluation designed to provide a better understanding of the motor-control processes of individuals with concussion. Despite the widespread use of the BESS, a fundamental gap exists in applying this tool to young athletes, as normative values are lacking for this population.

Objective: 

To determine age- and sex-specific normative values for the BESS in youth, high school, and collegiate athletes.

Design: 

Cross-sectional study.

Setting: 

Local youth sport organizations, high schools, and colleges.

Patients or Other Participants: 

Student-athletes (N = 6762) completed preseason baseline concussion testing as part of a comprehensive concussion-management program. Groups were youth males aged 5 to 13 years (n = 360), high school males aged 14 to 18 years (n = 3743), collegiate males aged 19 to 23 years (n = 497), youth females aged 5 to 13 years (n = 246), high school females aged 14 to 18 years (n = 1673), and collegiate females aged 19 to 23 years (n = 243).

Main Outcome Measure(s): 

Errors according to the BESS specifications.

Results: 

Performance on the BESS was worse (P < .01) in youth athletes than in high school and collegiate athletes. In the youth and high school cohorts, females exhibited better scores than males (P < .05). Sex was not a factor for collegiate athletes. Data from the youth cohort were further subdivided into 4-year bins to evaluate potential motor-development differences. The error count was highest for 5- to 9-year-old males and decreased with age.

Conclusions: 

Performance on the BESS depended on sex and age, particularly in youth athletes. These sex- and age-specific normative values provide a reference to facilitate and unify clinical decision making across multiple providers caring for youth athletes with concussions.

Authors: O'Malley Edwenia , Richter Chris , King Enda , Strike Siobhán , Moran Kieran , Franklyn-Miller Andrew , Moran Ray
Published: August 2018

Context: 

Despite an increase in the literature, few definitive guidelines are available to determine when an athlete has been fully rehabilitated after anterior cruciate ligament reconstruction (ACLR).

Objective: 

To examine countermovement jump and isokinetic dynamometry measures to (1) identify which measures can best distinguish between ACLR and control participants and (2) provide normative values for identified measures in young adult male multidirectional field-sport athletes.

Design: 

Cross-sectional study.

Setting: 

Orthopaedic hospital.

Patients or Other Participants: 

Young adult male multidirectional field-sport athletes (n = 118) who had undergone unilateral patellar-tendon graft ACLR at least 6 months earlier and healthy male participants (n = 44) with no previous knee injury.

Intervention(s): 

Single-legged countermovement jump (SL CMJ).

Main Outcome Measure(s): 

Three-dimensional biomechanical analysis of the SL CMJ and mean peak concentric knee-extension and -flexion torque using isokinetic dynamometry (ISO) were compared in the 2 groups. A stepwise logistic regression was carried out to identify the best predictors of ACLR- or control-group membership (SL CMJ height, limb symmetry index, peak power, joint power contribution, ISO peak torque, limb symmetry index variables).

Results: 

The control group differed strongly from the ACLR group in isokinetic knee-extension peak torque (d = –1.33), SL CMJ performance (d > 0.4), and limb symmetry measures in both ISO and jump outcomes (d > 1.1). The combination of measures from both ISO and SL CMJ identified group membership with an accuracy of 89%.

Conclusions: 

Rehabilitation of ACLR patients may be complete when they achieve isokinetic knee-extension peak torque of 260% (±40%) body mass, SL CMJ performance of >17 cm (±4 cm), and reach-limb symmetry measures of >90% in both strength and jump outcomes. The outcomes in the control group can inform return-to-play criteria for young adult male multidirectional field-sport athletes after ACLR.

Abstract. Several previous field studies have reported unexpectedly large
concentrations of hydroxyl and hydroperoxyl radicals (OH and HO2,
respectively) in forested environments that could not be explained by the
traditional oxidation mechanisms that largely underestimated the
observations. These environments were characterized by large concentrations
of biogenic volatile organic compounds (BVOC) and low nitrogen oxide
concentration. In isoprene-dominated environments, models developed to
simulate atmospheric photochemistry generally underestimated the observed OH
radical concentrations. In contrast, HO2 radical concentration
showed large discrepancies with model simulations mainly in non-isoprene-dominated
forested environments. An abundant BVOC emitted by lodgepole and
ponderosa pines is 2-methyl-3-butene-2-ol (MBO), observed in large
concentrations for studies where the HO2 concentration was poorly
described by model simulations. In this work, the photooxidation of MBO by OH
was investigated for NO concentrations lower than 200 pptv in the
atmospheric simulation chamber SAPHIR at Forschungszentrum Jülich.
Measurements of OH and HO2 radicals, OH reactivity (kOH),
MBO, OH precursors, and organic products (acetone and formaldehyde) were used
to test our current understanding of the OH-oxidation mechanisms for MBO by
comparing measurements with model calculations. All the measured trace gases
agreed well with the model results (within 15 %) indicating a well
understood mechanism for the MBO oxidation by OH. Therefore, the oxidation of
MBO cannot contribute to reconciling the unexplained high OH and
HO2 radical concentrations found in previous field studies.
Location of unbalance mass and supporting bearing for different type of balance shaft module
Authors: Kim Chan-Jung
Published: August 2018

Abstract. The dynamic characteristics of balance shaft module is
controlled by the design of rotating parts as how to allocate both a
unbalance mass and a supporting bearing so that the concept design of a rotor
structure is the key issue on determining the overall quality of dynamic
performance as well as fatigue resistance. Even the design on balance shaft
has some limitation from the lay-out of a vehicle engine system, there is
still chance to enhance the reliability of the balance shaft module by the
promising design model of the rotor structure including support bearing
locations. In this paper, an optimal location of unbalance mass and
supporting bearing is proposed to make an efficient conceptual design using
an objective function to minimize a bending deformation of rotor as well as a
reaction force at supporting bearing. In addition, the application of design
optimization of a balance shaft model is explained using an in-house program
for inline 3-cylinder and inline 4-cylinder engine, respectively.
Learning Effects, Achievement Goals and Time Constraints in Accounting Education: Findings from Experiments
Authors: Cheng Pi-Yueh , Fang Miao-Ling
Published: August 2018

Accounting education has been a topic of great concern to scholars, and teachers of accounting want to enhance students’ learning performance. Thus, in this study, we conducted laboratory experiments to investigate how mastery/performance achievement goal orientations influence the accounting performance of students. Ninety undergraduates from Tainan Technology University participated in this study. The experiment examined how the type of student achievement goal and the test time influenced accounting performance. A two-way between-participants factorial design of achievement goal (mastery vs. performance) × test time (30 vs. 40 vs. 50 min) was adopted. The results of students’ score changes from pre-test to post-test revealed that those students with a mastery achievement goal had a better learning effect than those with a performance achievement goal. The main effect of test time also showed a significant difference. The score change in the low-difficulty condition (longest time) was significantly higher than that in the moderate-difficulty condition (intermediate amount of time), and the score change in the moderate-difficulty condition was significantly higher than that in the high-difficulty condition (shortest time). Lastly, the two-way interaction of achievement goal type and test time was significant. The effect of test difficulty on score change was contingent on the type of achievement goal.
Breaking the Myth: Bocángel's New Narcissus
Authors: Mercado Leticia
Published: August 2018

Gabriel Bocángel (1603–1658) gives the Ovidian myth of Narcissus a baroque twist in a game of mirrored images, voices, and silences. In redondilla LX, Celia looks into a mirror that breaks suddenly, multiplying her image into miniature portraits. Unlike Ovid's version of the story, it is not the lady who, like Narcissus, dies, enraptured in self-contemplation, but the lookingglass itself. Sonnet XII represents the “death” of the glass as the breaking of both its surface and its silence. The glass, now endowed with a voice, turns into a true mirror that echoes the message of desengaño: not only that suffering is the inevitable consequence of unfulfilled carnal desire, but also that beauty and artistic endeavor are both fragile and futile.
El anonimato como performance textual: ‘Clarinda’ y Amarilis reconsideradasAnonimity as Textual Performance: Reconsidering ‘Clarinda’ and Amarilis
Authors: Barco Valeria del
Published: August 2018

This article reconsiders anonymity in the works of the Peruvian poets known as ‘Clarinda’ and Amarilis. By analyzing this topic from the theory of reception, I argue that far from experiencing the lack of an author as a problem, we can understand it in the context of production and textual reception as planned by the poets. I propose that if anonymity in a text is a conscious choice made by the author, this lack of signature can be thought as a textual strategy purposefully employed by the producer of the text. Thus, both poets transform the social practice of the tapada into a textual strategy of freedom and expression.
Primero sueño y Segundo sueño, un diálogo poético trasatlánticoPrimero sueño and Segundo sueño, a Transatlantic Poetic Dialogue
Authors: Cortés-Vélez Dinorah
Published: August 2018

In Antología poética en honor a Góngora (1927), Gerardo Diego highlights the Gongorism of Sor Juana's First Dream and describes her verses as “convoluted.” In Homenaje a Sor Juana Inés de la Cruz (1952), Diego includes a poem of his own entitled Second Dream, which is a tribute to the First Dream. The present essay focuses on Diego's textual dialogue with basis on these two divergent moments, in order to demonstrate that reticence (first moment) and reappropriation (second moment) are representative of an effort of self-assertion of the Neo-Gongorist poet. Hans Robert Jauss's concept of ‘reception aesthetics’ allows examination of the aesthetic distance between the First Dream and the Second Dream in view of the disparity between the horizons of expectations of both poets. I propose, however, that it is necessary to examine this aesthetic distance with a reading that takes into account the variable of gender.

Authors: Vanidassane Ilavarasi , Malik Rupali , Jain Neelima
Published: August 2018

Introduction: Reduced lung function in diabetes has been described for long but its clinical importance is not yet clear. Also, limited literature is available regarding its association with sugar control, and its correlation with inflammatory markers. Thus, we aimed to study the pulmonary function test abnormalities and systemic inflammation in type 2 diabetes mellitus. Material and methods: 100 patients with type 2 diabetes were divided into two groups depending on control of diabetes (group A–HbA1C ≤ 7% and group B-HbA1C > 7%). All the subjects selected underwent detailed evaluation including testing for HbA1C, HsCRP (high-sensitivity C-reactive protein), serum ferritin and serum fibrinogen, along with pulmonary function testing. Results: Percentage predicted FVC (forced vital capacity), FEV1 (forced expiratory volume in 1 second) and SVC (slow vital capacity) were significantly reduced, while mean values of inflammatory markers [fibrinogen (p < 0.001) and hsCRP (p < 0.002)] were significantly higher in uncontrolled diabetes group. There was a significant negative correlation between FEV1 (r = –0.739, p < 0.001), FVC (r = –0.370, p < 0.001), SVC (r = –0.635, p < 0.001) with HbA1C. HbA1C had a positive correlation with hsCRP (r = –0.308, p < 0.002) and fibrinogen (r = 0.388, p < 0.001). Conclusion: Pulmonary functions were decreased and inflammatory markers like hsCRP, fibrinogen, and ferritin significantly increased in uncontrolled diabetics. Also, a potential association was seen between higher values of inflammatory markers like hsCRP and fibrinogen and decrease in lung function. This information, requiring confirmation with larger multicentre studies, remains important because of potential epidemiological, clinical and therapeutic implications.
Pleiotropic Effect of Vitamin D in Cystic Fibrosis
Authors: Grzelak Teresa , Mikołajczyk Klaudia
Published: August 2018

Cystic fibrosis (CF) is the most common recessively autosomally and inherited disorder in the Caucasian population. It is incurable, multi-systemic disease with progressive course. CF is caused by CFTR gene mutation, the product of which is Cystic Fibrosis Transmembrane Conductance Regulator (CFTR). CF patients are exposed to fat-soluble vitamins deficiency, including vitamin D. It is due to the fat malabsorption (caused by exacerbation exocrine pancreatic insufficiency), decreased sun exposure (caused by receiving antibiotics photophobia), reduction of adipose tissue and insufficient supply with food. The discovery of vitamin D receptor (VDR) presence outside the skeletal system allowed to conclude, that vitamin D is responsible not only for mineral economy, but also for immunological processes, respiratory status, intestial microflora and cystic fibrosis – related diabetes (CFRD) course. Based on literature data, it is suggested that vitamin D plays an important role in the prevention of diseases coexisting with CF. The right dosage of vitamin D allows to maintain a better lung function and prevent chronic pulmonary infections. It has also been shown that normal levels of vitamin D may be important in increasing the chances of successful lung transplant surgery. Taking the wide spectrum of vitamin D effect into account, it is recommended to maintain serum concentrations above the minimum in patients with CF. In summary, maintaining the proper vitamin D levels in patients with CF is important because of its pleiotropic effect. It can be achieved through regular monitoring of vitamin D levels and individual supplementary dose for each patients.
2-Year Follow-Up of Lung Transplantation as a Treatment of Hereditary Hemorrhagic Telangiectasia (Osler-Weber-Rendu Disease)

Published: August 2018

Hemorrhagic telangiectasia (HHT) is a disease of initially mild course - manifesting with recurrent nosebleeds and increased fatigue. Nevertheless, its progression can deteriorate patient’s health. Solid organ transplantation becomes the only therapeutic option to save a life. The case report describes a 19-year-old female patient who was diagnosed with HHT and qualified for lung transplantation. She met the Curacao criteria for HHT (¾). Her health deteriorated significantly to the point of the referral to Department of Cardiac, Vascular and Endovascular Surgery and Transplantology in Silesian Center for Heart Diseases. Due to her condition, she was qualified for lung transplantation as one diagnosed with pulmonary arteriovenous malformations and then transplanted at the age of 17. A direct postoperative period was complicated by HSV2 infection of the wound. 18 months after the procedure, the patient underwent acute cholangitis. The presence of portal and systemic fistulas was noted and the final diagnosis of HHT was made. Despite the fact that proper diagnosis was made posttransplant, it was a good treatment. The patient is currently 2 years after the lung transplantation and feels good. Lung transplantation is a viable therapeutic option for patients with HHT as there are reports of other patients who have benefited from lung transplantation after other therapeutic options were exhausted.

Formidlingsbegrebets digitalisering i Danmark. Diskursive implikationer og praktiske konsekvenser
Authors: Rudloff Maja
Published: August 2018

This article investigates the development of the concept of museum communication in a Danish cultural political context from 2006 until 2013 and the practical consequences a changed interpretation of the concept has for the Danish state-owned and state-supported museums. The main argument is that the concept of cultural communication, specifically concerning museums, has undergone a transformation towards having a digital content of meaning in recent years. And furthermore: that the meaning ascribed to the concept has practical impact. The increased attention paid to communication, particularly digital communication, in the tasks of the museums, is redistributing the museums’ resources, foci and priorities. is call for a more thorough discussion of what museums must and can be in the future – and not least for whom.
Making things matter. Meaning and materiality in museum displays
Authors: Bäckström Mattias
Published: August 2018

An international and trans-institutional study, the present postdoctoral project analyses the production of prehistory, art history and cultural history in various museum displays in Berlin, Copenhagen, London and Stockholm, from c. 1880 to c. 1920. The collection galleries and permanent exhibitions are analysed as interfaces of meaning and materiality, with a focus on the different concepts of knowledge that were brought into play when making history, namely scholarly knowledge, aesthetic experience, didactic learning, technical expertise and notions of how to live well. More specifically, the project combines two theoretical perspectives, the poetics of display and displays as mediations, and analyses how museums made history through more or less locally decided interconnections of moral models, display techniques, historical remains and reproductions, and didactic, epistemological and aesthetic ideas. The three-year project, 2015–2018, is conducted partly in the aforesaid cities, and chiefly at the Centre for Museum Studies, IKOS, University of Oslo.
Motion and flow in heritage institutions. Two cases of challenges from within
Authors: Hansen Christine , Holmberg Ingrid Martins
Published: August 2018

Through two case studies, one in Australia and one in Sweden, this paper looks at how seemingly stable heritage institutions such as museums, archives and government repositories can be reformed through engagement with subaltern subjects. Highlighting institutional permeability rather than conservative resistance, we follow the movement of this “motion and flow” and how it in turn affects ideas of what constitutes both “heritage experts” and broader notions of “heritage”. Although these examples vary in scale, they nevertheless share the contemporary myths and misunderstandings around what happens when heritage institutions meet with subaltern peoples and the challenges they offer from within for the inner workings of the institution. In one case a radical inclusion has been achieved while the other has begun what is likely to be a long-term, complex, cultural conversation. Taken together, these institutional achievements may offer an alternative to recent critiques of official heritage institutions as merely inheritors of a nineteenth-century legacy.

Temat för det här numret av Nordisk Museologi – Museer og ulikheters kulturelle dynamikk – är detsamma som för en session på den 32. Nordiska etnolog- och folkloristkongressen i Bergen, juni 2012. Syftet var att sätta fokus på de kulturhistoriska museerna som platser för kunskapsproduktion och kunskapsförmedling, men samtidigt som arenor för presentation och produktion av kulturell skillnad. En utgångspunkt var dessa museers roll i det moderna nationsbyggandet och hur de har fått en självskriven position i västvärldens självbild och självförståelse. Museerna är tätt förbundna med begrepp som kulturarv, historia och tradition, men vi ville belysa den dynamik som kan uppstå om man ifrågasätter det självklara och riktar blicken mot olikheter och skillnader. Kan man se hur kulturell åtskillnad har skapats, befästs och förändrats i museerna? Har kulturell variation fått framträda, och i så fall på vilka villkor? Utifrån detta ville vi också problematisera museerna som arenor för historiska framställningar och undersöka hur tidsperspektivet kan inverka på förståelsen av kulturell olikhet i samtiden.
But where is György Dózsa? – are there objective heroes in history?
Authors: Hieta Hanneleena
Published: August 2018

In this paper, the author focuses on the controversial life and death of György Dózsa, the sixteenth-century mercenary and leader of a peasant revolt against the upper classes, to address the questions of what is heroism and who gets to define it. Whereas earlier Marxist historians considered him a hero for challenging the rule of the upper classes (while at the same time ignoring his upper-class background), twenty-first century historiography has omitted him from the pantheon of Hungarian national heroes. This omission is highlighted most clearly in Ópusztaszer National Historical Memorial Park near Szeged in south-eastern Hungary, a region claiming to be the place where the Hungarian state was born. The statues erected to commemorate one thousand years of Hungarian statehood did not include György Dózsa; instead, they commemorate those figures who best symbolized the stability of the state. Internal dissent does not make for good national heroes.
Kärnkraftverk som minnesplatser

Is it possible to imagine a nuclear power plant as a memory site? In many respects, the answer is yes. Nuclear power already forms a part of cultural history museum exhibitions and closed-down nuclear plants have been documented and analysed from a heritage perspective. However, they are also highly controversial places for remembering the past, since their significance is exceptionally ambiguous. The plants stand for potential catastrophe, the complicated management of the radioactive waste and are often associated with nuclear weapons but – at the same time – they also imply hope in the future and a possible answer to the climate threat. Are closed-down nuclear power plants to be preserved in some way, and in that case why? And is our understanding of the concept of heritage to change in some respects as a consequence of this?
Mille Gabriel og Jens Dahl (red.) (2008): Utimut. Past Heritage – Future Partnership. Discussions on Repatriation in the 21st Century
Authors: Bjørst Lill Rastad
Published: August 2018

“Utimus Heritage – Future Partnerships” er det synlige produkt af en konference afholdt i Nuuk i 2007 med emnet repatriering og kulturarv. Normalt bliver denne slags udgivelser sjældent læst fra ende til anden, da den består af en masse små artikler, som med rette også kan nydes hver fra sig. Men da jeg har fået den fornemme opgave at anmelde hele bogen, vil jeg her anmelde den som et samlet værk.

Fredrik Svanberg & Katty H. Wahlgren: Publik arkeologi
Authors: Bergdahl Ewa , Zipsane Henrik
Published: August 2018

Den här boken har betraktats lite som en manifestation för ”public archaeology’s” ankomst till Sverige. Om den också är tänkt som en sådan introduktion för hela Skandinavien är tveksamt, eftersom samtliga referenser enbart är svenska eller engelska. Begreppet ”public archaeology” har huvudsakligen utvecklats och tillämpats i UK och som så mycket annat inom svensk museivärld idag kommer inspirationen även denna gång från väster.

I august 2007 var vi mange, der drog til ICOMs konference i Wien. Som lektor i museologi og redaktør af Nordisk Museologi meldte jeg naturligvis mig til ICOFOMs internationale seminar, der forløb over to dage fra 20.-22. august og blev ledet af den tyske kunsthistoriker og museolog Hildegard K. Vieregg. Temaet for seminaret var ”Museology and Techniques”. Museologer fra hele verden deltog – Argentina, Australien, Østrig, Belgien, Brasilien, Kina, Italien, Mexico, Rusland, Spanien, Taiwan, USA m.v. Det var på seminaret fantastisk at opleve, at museologien synes at være blevet accepteret som en videnskabelig disciplin. Efterhånden som seminarets mange spændende oplæg afløste hinanden, stod det imidlertid klart, at ICOFOM kæmper om en fælles forståelse af videnskabelighed, hvilket er helt naturligt, når så mange lande og forskellige uddannelseskulturer mødes og diskuterer.

It sought to introduce and discuss the range and possibilities of a growing awareness of place and space by inviting five senior researchers from the Nordic countries to give lectures and participate in workshops with the PhD students, who also presented papers relating to the theme of the seminar.
From a history of war into a multicultural urban environment: A cultural impact assessment of the conservation of the Swedish-Russian Fortress of Lappeenranta, Finland
Authors: Niinisalo Suvi
Published: August 2018

Finland, under Swedish rule at the time, started constructing the Lappeenranta Fortress in the 1720s for defence against an eastern threat. A small town had been founded on the site as early as 1649. In 1741, the Russians invaded the fortress in a fierce battle. Russians, led by Aleksandr Suvorov, started to improve the fortress in the late 18th century. The oldest buildings in the fortress date back to this time. When Finland was annexed into the Russian Empire as an autonomous grand duchy, the fortress was employed as a correctional facility for prisoners. After the Second World War, the fortress was left to deteriorate, but in the 1970s a 30-year conservation project was launched. This article explores the effects of this conservation work on the city of Lappeenranta as well as on its inhabitants.
