Authors: Putri Meylda Kurnia Emylia
Published: September 2019

Batuan mulia (gemstone) merupakan salah satu kekayaan alam yang dapat dijadikan perhiasan dan koleksi. Terdapat beberapa jenis batuan seperti ruby, sapphire, zamrud, topaz, kecubung, dan kalimaya. Jenis batuan mulia tersebut dapat dikenali berdasarkan tekstur, motif, dan warnanya. Keberagaman atas jenis batuan mulia akan menjadi kendala bagi konsumen untuk mengidentifikasi bebatuan asli, palsu dan sintetis dikarenakan minimnya akan pengetahuan dan kemampuan individu dalam mengidentifikasi bebatuan mulia. Kemiripan Antara batuan mulia asli, sintetis, dan palsu menjadi suatu permasalahan dalam pemilihan batuan tersebut. Berdasarkan permasalahan yang telah dijabarkan maka dengan dibuatnya sistem basis jaringan saraf tiruan dapat mengidentifikasi dan mengenali batuan mulia, asli, palsu, atau sintetis dikarenakan jaringan saraf tiruan merupakan salah satu ilmu komputer yang dapat mempelajari dan menirukan kerja otak manusia dibidang pengelompokan dan pengenalan pola. Untuk pengaplikasian tersebut, algoritma yang akan digunakan yaitu backpropagation dan hasil dari keakurasian adalah 85%.

Authors: Hermawan Edy
Published: September 2019

Mammografi merupakan salah satu alat terbaik sampai saat ini untuk melakukan deteksi dini terhadap keberadaan kanker  payudara. Penggunaan mammografi efektif menurunkan tingkat kematian akibat kanker payudara sebesar 30% sampai 70%. Akan tetapi, terdapat kesulitan melakukan interpretasi terhadap mammogram sebagai hasil luaran dari mammografi karena sangat bergantung pada kualitas mammogram dan pengalaman dari ahli radiologi dalam mendeteksi lesi kanker payudara. Computer Aided Diagnosis (CAD) sebagai pembaca ganda mammogram dapat dipergunakan untuk  meningkatkan akurasi deteksi dan segmentasi dari ahli radiologi. Penelitian ini merupakan upaya untuk melakukan deteksi dan segmentasi dengan menggunakan teknik pemrosesan citra terhadap objek yang dicurigai sebagai lesi kanker payudara pada citra mammogram. Untuk meningkatkan akurasi deteksi dan segmentasi maka dilakukan preprocessing untuk mengurangi noise dan meningkatkan homogenitas aras keabuan mammogram. Deteksi dan segmentasi terhadap keberadaan lesi kanker dilakukan dengan menerapkan metode active contour Lankton. Hasil penelitian menunjukkan metode yang diajukan mampu melakukan deteksi dan segmentasi terhadap lesi kanker payudara dengan baik. Wilayah kanker payudara dapat terdeteksi sesuai dengan wilayah kanker  payudara yang dideteksi radiolog dan tersegmentasi dengan jelas. Fitur FO dan GLCM hasil ekstraksi dari lesi kanker payudara dapat diperoleh signifikan tanpa terlalu banyak terkontaminasi dari fitur non lesi kanker payudara. Fitur FO dan GLCM dari lesi kanker payudara hasil ekstraksi  dapat dipergunakan sebagai input untuk analisis lanjutan berupa klasifikasi lesi kanker.

Instantaneous fMRI based cerebral parameters for automatic Alzheimer, mild cognitive impairment and healthy subject classification
Authors: Seraj Esmaeil , Yazdi Mehran , Shahparian Nastaran
Published: September 2019

Automatic identification and categorization of Alzheimer’s patients and the ability to distinguish between different levels of this disease would be very helpful to the research community studying this disease since non-automatic approaches are both very time-consuming and highly dependent upon the experience of experts. Here, it is proposed that instantaneous cerebral phase and envelope information from functional magnetic resonance imaging data is of use to discriminate between Alzheimer’s patients, mild cognitively impaired subjects and healthy individuals. Following a region-of-interest analysis of functional magnetic resonance imaging data, different features including power, entropy, and coherency features are derived from the instantaneous phase and envelope signal sequences. Various sets of features are calculated and fed to a sequential forward floating feature selection algorithm to identify the most discriminative and informative feature sets. A Student’s t-test was employed to select the most relevant features from the sets. Finally, a K-nearest neighbor classifier is used to distinguish between classes in a three-class categorization problem. The reported performance in overall accuracy using functional magnetic resonance imaging data of 111 combined participants is 80.1% with 80.0% sensitivity for the distinction of both Alzheimer’s and healthy categories. This is comparable to the state-of-the-art approaches recently proposed for this task. The significance of obtained results was statistically confirmed by the evaluation of standard classification performance indicators. Results illustrate that the analytic phase and envelope feature indices derived from the region of interest signals described here are significant discriminators suited to distinguish between Alzheimer patients and healthy subjects.
The Wnt/β-catenin signaling pathway affects the distribution of cytoskeletal proteins in Aβ treated PC12 cells
Authors: Tian Zhifeng , Zhang Xiaoling , Zhao Zhijun , Zhang Fuhua , Deng Tongxing
Published: September 2019

Alzheimer’s disease is pathologically characterized by the presence of senile plaques and neurofibrillary tangles in the central nervous system. Amyloid β-protein is toxic to neurons and induces phosphorylation of Tau protein, which accumulates in paired helical filaments and leads to the formation of neurofibrillary tangles. This study is focused on the Wnt/β-catenin pathway influence on Tau phosphorylation and the distribution of microtubules and neurofilaments in adrenal pheochromocytoma cells. It was found that neurofilament heavy polypeptide and microtubule-associated protein-2 aggregated after treatment with Aβ1-42. Treatment with Wnt5a reduced this aggregation, while Dickkopf-1 treatment promoted microtubule and neurofilament aggregation. Furthermore, Tau phosphorylation at Ser396, Ser422, and Ser199 was significantly reduced after Wnt5a treatment, whereas Dickkopf-1 increased the level of phosphorylation. These results suggest that the Wnt/β-catenin pathway influences the distribution of microtubules and neurofilaments, possibly by modulating the phosphorylation of Tau protein in adrenal pheochromocytoma cells.

Published: September 2019

Rats were divided into six groups: sham/control, Dl-3-n-butylphthalide, P1 (low phenytoin, 100 mg/kg), P2 (high phenytoin, 200 mg/kg), NP1 (Dl-3-n-butylphthalide 80 mg/kg, phenytoin 100 mg/kg), NP2 (Dl-3-n-butylphthalide 80 mg/kg, phenytoin 200 mg/kg). Hematoxylin/eosin and Nissl staining showed that, compared to the sham/control group, the Dl-3-n-butylphthalide group had no obvious hippocampal and cerebellar neuron loss, but there was a significant neuron loss in the P1 and P2 groups (P < 0.05), which was more obvious in the P2 group (P < 0.05). The positive expression of Bax and Bcl-2 proteins in hippocampal and cerebellar neurons was not significantly different between sham and Dl-3-n-butylphthalide groups; however, compared to sham, Bax expression was significantly increased and Bcl-2 was significantly decreased in the hippocampal and cerebellar neurons of rats in both P1 and P2 groups (P < 0.05), being more obvious in the P2 group (P < 0.05). Furthermore, the administration of Dl-3-n-butylphthalide attenuated the deleterious effects of phenytoin (P < 0.05). Our results indicate that phenytoin causes apoptosis of hippocampal and cerebellar neurons in rats in a dose-dependent manner, with the effect of a higher dose being more obvious, whereas, Dl-3-n-butylphthalide inhibits the phenytoin-induced apoptosis of neurons and has a neuroprotective role.
The therapeutic effect of quetiapine on cognitive impairment associated with 5-HT1A presynaptic receptor involved schizophrenia
Authors: Han Dai , Shi Shenxun , Luo Hong
Published: September 2019

The cognitive impairment associated with schizophrenia is highly prevalent and affects the overall functioning of subjects. The stimulation of the serotonin 1A receptor is a primary characteristic of some atypical antipsychotic drugs. We measured the levels of cognitive impairment using the Morris water maze test and protein kinase A activity in hippocampal neurons on presynaptic and postsynaptic serotonin 1A receptors to investigate the effect of dizocilpine-induced cognitive impairment associated with atypical antipsychotic drugs in rats treated by quetiapine alone or combined with WAY100635/tandospirone. The results of the Morris water maze test presented evidence that quetiapine alone alleviated the cognitive impairment associated with atypical antipsychotic drugs induced by dizocilpine. However, quetiapine plus WAY100635 induced no improvement of cognitive impairment associated with atypical antipsychotic drugs. The results of protein kinase A assay suggested that neither quetiapine alone nor in combination with tandospirone, but not quetiapine plus WAY100635, raised protein kinase A activity in hippocampus neurons. The present study demonstrated the key role of presynaptic serotonin 1A receptors on the therapeutic effect of quetiapine on cognitive impairment associated with atypical antipsychotic drugs. Moreover, that protein kinase A activity in hippocampal cells is involved in the mechanism of quetiapine's effect on cognitive impairment associated with atypical antipsychotic drugs.
Mechanisms contributing to the genesis of hypoglossal preinspiratory discharge
Authors: Ghali Michael G. Z.
Published: September 2019

Preinspiratory discharge manifests in the neuronal recordings of the pre-Bötzinger complex, parafacial respiratory group, retrotrapezoid nucleus, and Kölliker-Fuse nucleus, as well as the efferent neural discharge of respiratory-related nerves innervating upper airway musculature. This neural component of triphasic eupnea contemporaneously contributes to the genesis of native and originate respiratory rhythmic activity, as well as the preinspiratory component of efferent neural respiratory discharges. In the course of our investigations evaluating hypoglossal discharge in response to asphyxia, we noted a curious pattern of neural respiratory recovery following postasphyxia resuscitation in hypoglossal, vagal, and phrenic neurograms in unanesthetized decerebrate rats. Specifically, we observed a gradual return of a pseudobiphasic eupnea characterized by initial transition bursts followed by robust eupneic bursts with dynamics inclusive of a gradually and progressively increasing duration of the hypoglossal eupneic bursts and duration and amplitude of the preinspiratory component of these bursts, as well as progressively lengthening expiratory interval between these bursts in the phrenic nerve discharge. This was followed by conversion to regular triphasic eupnea. We discuss our extrapolations based on these findings regarding eupneic respiratory central pattern generation and mechanisms contributing to the genesis of preinspiratory activity in hypoglossal discharge.
Statistical algorithms for emotion classification via functional connectivity
Authors: Jahromy Fatemeh Zareayan , Bajoulvand Atena , Daliri Mohammad Reza
Published: September 2019

Pattern recognition algorithms decode emotional brain states by using functional connectivity measures which are extracted from EEG signals as input to the statistical classifiers. An open-access EEG dataset for emotional state analysis is used to classify two dominant emotional models, based on valence and arousal. To calculate the functional connectivity between all available pairs of EEG electrodes four different measures, including Pearson’s correlation coefficient, phase-locking value, mutual information, and magnitude square coherence estimation, were used. Three kinds of classifiers were applied to categorize single trials into two emotional states in each emotional model (high/low arousal, high/low valence). This procedure resulted in decoding performance of 68.30% and 60.33% for valence and arousal respectively in test trials which were significantly higher than chance (≈ 50%, t-test, and significance level of 0.05). The results obtained using a phase-locking value approach were significantly better than previous findings on the same data set. These results illustrate that functional connectivity between distinct neural populations can be considered as a neural coding mechanism for intrinsic emotional states.

Published: September 2019

Cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy is a rare form of inherited cerebral small vessel disease associated with mutations in the high-temperature requirement serine peptidase A1 gene. As of now, only about 50 cases have been reported. In 2012, our group reported a family with a novel mutant of the high-temperature requirement serine peptidase A1 gene in China for the first time. To further explore the molecular pathogenesis of cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy, a recombination mouse model expressed human high-temperature requirement serine peptidase A1 gene mutant identified by our group was generated using the Donor & Clustered Regularly Interspaced Short Palindromic Repeats/Cas9 system and termed the Mut-high-temperature requirement serine peptidase A1 geneL364P mouse model. Results show that Mut-high-temperature requirement serine peptidase A1 geneL364P mice present similar pathological characteristics to patients with cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy, suggesting that the Mut-high-temperature requirement serine peptidase A1 geneL364P mouse model was generated successfully. Moreover, apoptosis was induced in mouse brain vascular smooth muscle cells derived from Mut-high-temperature requirement serine peptidase A1 geneL364P mice. In summary, the cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy mouse model described in this study will be beneficial to demonstrate the pathological mechanism of cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy and provide new therapeutic targets for clinical treatment.
New insights into the immunomodulatory role of exosomes in cardiovascular disease
Authors: Jiang Wenyan , Wang Mei
Published: September 2019

Exosomes, nanosized lipid bilayer membranous vesicles, are secreted by a variety of cells and contain protein, lipids, mRNA, miRNA, and signaling molecules that participate in intercellular material transfer and information exchange through binding, fusion or endocytosis. Exosomes mediate the gene expression of target cells and regulate pathological and physiological processes, thereby playing a key role in the occurrence and development of various diseases. Accumulated studies has shown that exosomes hold therapeutic potential though their anti-apoptotic and anti-fibrotic roles. They also have been shown to promote angiogenesis, inhibit ventricular remodeling and improve cardiac function, as well as inhibiting local inflammation and regulating the immune response. As such, exosomes represent a new target for the treatment of cardiovascular diseases. This review summarizes the literature in this field to date, including the basic biological characteristics of exosomes, and new progress in the understanding of the mechanisms of their involvement in immune regulation in cardiovascular diseases. In this way, it servrs as a basis for future research and the development of therapeutic exosomes.

Authors: Wang Zheng , Wang Zhan , Wang Tiezhong , Yuan Jiayang , Wang Xuechen , Zhang Zhiguo
Published: September 2019

Myocardial ischemia-reperfusion (I/R) injury is leading cause of death worldwide. miR-34a-5p was up-regulated in myocardial ischemia-reperfusion injury rats. We aim to explore how miR-34a-5p inhibition protected myocardium against I/R injury in both cell and animal models. In vivo rat and in vitro cell model were firstly constructed. Quantitative real-time polymerase chain reaction was employed to investigate expression of miR-34a-5p and its target genes. Functional assays were conducted to detect the impact of miR-34a-5p on myocardial I/R injury. Enzyme-linked immunosorbent assay was performed to validate the expression levels of marker proteins of ischemia-reperfusion I/R-induced myocardial injury. MTT was performed to assess the cell viability and flow cytometry was utilized to detect cell apoptosis and reactive oxygen species accumulation. The interaction between miR-34a-5p and Notch Receptor 1 were also examined through luciferase reporter assay. miR-34a-5p was up-regulated post-reperfusion at rat myocardium. miR-34a-5p inhibitor attenuated myocardial ischemia-reperfusion injury, as shown by decreasing apoptosis rate, reducing infarct size and reactive oxygen species accumulation. In in vitro cell model, miR-34a-5p inhibitor also promoted cell proliferation, inhibited cell apoptosis and reactive oxygen species accumulation through targeting Notch Receptor 1 signaling. Our results revealed that miR-34a-5p knocking down attenuated myocardial I/R injury by promoting Notch Receptor 1 signaling-mediated inhibition of reactive oxygen species accumulation and cell apoptosis. Hence, miR-34a-5p might be a potential target for treatment of myocardial ischemia-reperfusion injury.

Adjusting for expected adjusted effect
Authors: Sorjonen Kimmo , Melin Bo , Ingre Michael
Published: September 2019

The point that adjustment for confounders do not always guarantee protection against spurious findings and type 1-errors has been made before. The present simulation study indicates that for traditional regression methods, this risk is accentuated by a large sample size, low reliability in the measurement of the confounder, and high reliability in the measurement of the predictor and the outcome. However, this risk might be attenuated by calculating the expected adjusted effect, or the required reliability in the measurement of the possible confounder, with equations presented in the present paper.

Published: September 2019

The interaction of Methylene blue with Cetylpyridinium chloride (CPC) in a series of solvents containing 0.1, 0.2 and 0.3 volume fractions of methanol in water were studied at room temp (300±2 K) by UV-Vis spectrophotometer. The CPC concentrations were varied from 0.2 x 10-3 to 2 x 10-3 mol dm-3. A fixed dye concentration of 2.5 x 10-5 mol dm-3 was used for this purpose. The spectrum analysis was performed for both the dye solution and mixtures containing dye and surfactant of different concentrations. The dye solution showed the absorbance maximum at 664 nm and a shoulder at 610 nm. In 0.3 volume fraction of methanol as solvent, the dye and surfactant mixed solution showed a shift in peak values towards shorter wavelength (blue shift) from peak of the dye solution. The shift in peak increased with increase in surfactant concentration up to 0.6 x10-3 mol dm-3, beyond which no further shift increment occurred. In the case of 0.1 and 0.2 volume fractions of methanol in water, no shift in peak was found at all concentrations of dye and surfactant. The absorbance of dye and surfactant mixed solution decreased gradually in 0.2 volume fraction of methanol with increase in surfactant concentration, whereas no significant change in absorbance was seen in 0.1 volume fraction of methanol. The shift decreased gradually with decrease in methanol concentration in the solvent.

Authors: Bhattarai Geeta , Bhandari Sanjay , Khadka Dambar Bahadur
Published: September 2019

Masyaura, an ethnic, fermented and dried, cone shaped, black or green gram product, is prepared by Nepalese people living in the Himalayas. Masyaura is especially prepared from split black gram (Phaseolus mungo) and Colocasia (Colocasia esculenta) or radish and ash gourd depending upon the availability of raw materials. The taste and texture are the fundamental characteristics of Masyaura. Breakage or loss of integrity after drying, during handling, packing and cooking are observed as a common problems of Masyaura. In this study, effect of addition of mashed potato on physiochemical and sensory quality of Masyaura was studied. Masyaura prepared by using black gram and colocasia tuber in the ratio 2:1 with fermentation time of 2 h was taken as control. Black gram was partially replaced by different proportion of mashed potato (6.25, 12.5, 18.75 and 25 parts by weight) to study the effect on physiochemical and sensory quality of Masyaura. Rehydration ratio, bulk density and disintegration time of Masyaura varied from 2.60:1 to 3.45:1, 510 to 654 kg/m3 and 35.75 to 45.91 min respectively. Masyaura prepared by incorporating mashed potato had higher bulk density, longer disintegration time and lower rehydration ratio compared to control. Sensory evaluation showed that 18.75 parts mashed potato incorporated Masyaura had the best sensory quality of all the proportions studied. Incorporation of mashed potato in partial replacement of black gram could significantly improve the textural property of Masyaura.

Authors: Kröger Sebastian , Bauer Harald , Reinhart Gunther
Published: September 2019

Kurzfassung

Produzierende Industrieunternehmen werden zunehmend durch den globalen Wettbewerb und die Marktmacht von Kunden in Käufermärkten beeinflusst. Darüber hinaus werden Lebens- und Innovationszyklen von Produkten und Maschinen immer kürzer. Um diesen Herausforderungen begegnen zu können, müssen Produktionssysteme regelmäßig angepasst werden, wodurch hohe Kosten entstehen. Die detaillierte Bewertung der Änderungskosten ist für produzierende Industrieunternehmen in der Praxis von hoher Relevanz. Veröffentlichungen aus den Bereichen des Änderungsmanagements und der Änderungsauswirkungsanalyse behandeln Kosten jedoch nur auf einem sehr allgemeinen Niveau. Der vorliegende Beitrag adressiert die Herausforderungen der Kostenbewertung von Änderungsauswirkungen in der Produktion durch eine anwenderfreundliche und praxisnahe Kostenstruktur. Aufgrund des Detaillierungsgrades der Kostenpositionen kann die Kostenstruktur als Grundlage für eine spätere quantitative Bewertung verwendet werden.

Kurzfassung

Kurze Produktlebenszyklen und individualisierte Produkteigenschaften erfordern Fertigungssysteme mit höchster Produktivität bei gleichzeitiger Flexibilität. Diese kontroversen Anforderungen lassen sich durch den Einsatz modularer Werkzeugmaschinen erfüllen. Modularität ermöglicht eine bedarfsgerechte Rekonfiguration der Werkzeugmaschine in zuvor definierten Flexibilitätskorridoren. Zu diesen Rekonfigurationen zählen im herkömmlichen Sinne zum Beispiel eine Änderung des Spannsystems, des Werkzeughalters oder der Bearbeitungsrichtung durch einen optionalen Drehtisch. Werden in der Entwicklungsphase diese starren Flexibilitätskorridore zu eng definiert, ist eine nachträgliche Anpassung der Maschinenstruktur in der Regel nicht ohne einen erheblichen finanziellen Aufwand möglich. In diesem Beitrag wird ein Baukastensystem vorgestellt, das es ermöglicht, die Maschinenstruktur in Form des Werkzeugmaschinengestells in ihren Grundzügen zu verändern. Auf Basis des Baukastensystems wurde eine prototypische 3-Achs-Portalfräsmaschine in Betrieb genommen. Erste Untersuchungen des dynamischen Maschinenverhaltens zeigen die Potenziale dieser modularen Werkzeugmaschine.

Published: September 2019

Kurzfassung

Neben den operativen Arbeitsprozessen in Unternehmen einer Wertschöpfungskette entscheidet vor allem die Effizienz der Kommunikationsprozesse über den Mehrwert eines Produktionsnetzwerkes. Auftretende Barrieren in einer interorganisationalen Kommunikation können daher zu Verzögerungen und Unterbrechungen im Produktionsprozess führen. Hierfür soll der folgende Beitrag ein Beschreibungsmodell liefern, mit dem Unternehmer Kommunikationsschnittstellen sowie -barrieren zielgenau zwischen Einzelorganisationen im Gesamtnetzwerk verorten können, um durch Gegenmaßnahmen möglichen Mehrkosten vorzubeugen.

Published: September 2019

Corrosion rate tests were carried out on carbon steel under concentration cells conditions of oxygen and sodium chloride. The effect of aeration in one compartment on the corrosion rate of both coupled metals was determined. In addition, the effects of time and temperatures on the corrosion rate of both coupled metals and galvanic currents between them were investigated. Corrosion potentials for the whole range of operating conditions under concentration cell conditions were also studied.   The results showed that under aeration condition, the formation of concentration cell caused a considerable corrosion rate of the Carbon steel specimens coupled in different concentrations of O2 and NaCl due to the galvanic effect. Aerating one compartment caused a noticeable increase in the corrosion rate of the coupled specimen in the other compartment due to the galvanic effect. Increasing temperature caused unstable trends in the free and galvanic corrosion potentials. Increasing the temperature led to an increase in the corrosion rate for both metals.

Nutzungsdauer und Präferenzen für Videospiele und ihre Zusammenhänge mit dem Ärgerempfinden bei Fehlern in der Schule
Authors: Frei Mischa , Süss Daniel
Published: September 2019

Der vorliegende Artikel geht der Frage nach, wie sich die Nutzungsdauer von und die Präferenzen für Videospiele auf die Ärgerdisposition und das Ärgerempfinden von 16- bis 25-Jährigen auswirken, wenn sie in der Schule Fehler begehen. Hierzu beantworteten 313 Probanden aus der Schweiz einen Online- Fragebogen. Dieser umfasste Fragen zu Videospielen, eine Vor- und Nachhermessung des Ärgerzustands sowie eine ärgerinduzierende Intervention dazwischen. Zusätzlich wurden soziodemographische Angaben und dispositionelle Ärgerdimensionen erhoben. Es zeigte sich, dass das Begehen von Fehlern in der Schule nicht zwangsläufig zu einer Ärgerzunahme führte. Etwa die Hälfte der Probanden zeigte danach sogar eine Ärgerreduktion. Jugendliche, welche Rollenspiele präferierten, zeigten eine höhere Ärgerkontrolle und drückten ihren Ärger weniger offen nach aussen aus als Jugendliche, welche Rollenspiele nicht präferierten. Jugendliche, welche Ego-Shooter oder Sport Games präferierten, richteten den Ärger weniger nach innen oder unterdrückten ihn weniger als Jugendliche, welche Ego-Shooter oder Sport Games nicht präferierten. Ausserdem zeigten Jugendliche, welche Sport Games präferierten, eine geringere Ärgerkontrolle als Jugendliche, welche Sport Games nicht präferierten. Weiter zeigte sich, dass männliche Jugendliche signifikant häufiger Videospiele spielen als weibliche. Die Nutzungsdauer von Videospielen korrelierte nicht signifikant mit der Ärgerzunahme. Somit kann nicht davon ausgegangen werden, dass Videospiele zu einer fehlerfreundlicheren Haltung führen. Es kann aber auch festgehalten werden, dass Videospiele keine verstärkende Wirkung auf das Ärgerempfinden haben. Medienkritische Haltungen konnten diesbezüglich nicht bestätigt werden.
