Prä-klinische Ansätze der Computerspiel- und Internetsucht: Schulbasierte Präventionsansätze, Medientraining und eine Empfehlung für finanzielle Obergrenzen bei In-Game-Käufen (MIRPPU)
Authors: Dreier Michael , Beutel Manfred E. , Müller Kai W. , Wölfling Klaus 
Published: November 2019

ZusammenfassungAusgewählte Beiträge eines internationalen Reviews zu schulbasierten Präventionsansätzen werden vorgestellt. Aufgrund ihrer Wirksamkeit werden 2 internationale Ansätze dargestellt. Ergänzend werden 5 z.T. evaluierte Ansätze des deutschen Sprachraumes beschrieben.Um einer subklinisch exzessiven Nutzungsgruppe ein benötigtes präventives Angebot zur Verfügung zu stellen, wurde von der Ambulanz für Spielsucht Mainz ein Medientraining konzipiert. Dieser verhaltenstherapeutische Präventionsansatz wird konzeptuell und mit seinen ersten Pilotergebnissen abgebildet. Beim Medientraining handelt es sich um eine gruppentherapeutische Frühintervention für Kinder und Jugendlichen mit problematischer Computerspiel- und Internetnutzung im Alter von 12–17 Jahren. Das prä-klinische Medientraining erweist sich als effektive Präventionsmaßnahme, denn es wurde eine deutliche Reduktion der Nutzungszeiten unter der Woche und am Wochenende erwirkt. Es kam zu Verbesserungen der Bewertung der Zukunftsperspektiven, einer Steigerung des Problemverständnis, einer Identifikation individueller suchtauslösender Faktoren, einer Verbesserung der familiären als auch schulischen Situation sowie zu einer Verbesserung der seelischen und körperlichen Situation.Strukturelle präventive Maßnahmen wie politische Regulationen des Jugendschutzes sollten weiter diskutiert und auf ihre Umsetzbarkeit hin überprüft werden. Eine Anregung dazu sind altersadäquate finanzielle Obergrenzen für Mikrotransaktionen (MIRPPU; Maximum Individual Revenue Per Paying User per month).

Published: November 2019

Abstract Learning ultrasound early in the medical school curriculum
helps students to understand anatomy and pathology and to perform defined
ultrasound standard views. Instructional videos are a potentially valuable
tool for improving the process of learning ultrasound skills. It was the aim
of the present study to investigate how students perceived instructional
videos as a learning aid, compared to other learning opportunities, in
preparation for an Objective Structured Clinical Examination (OSCE). Eleven concise ultrasound videos were created
and implemented in the 4th year at the Medical University of
Vienna. The videos illustrate the predefined examination process, image
optimization, and nine standardized ultrasound views. The videos were
available to be used in preparation for the practical ultrasound
examination, which was part of the objective structured clinical
examination. The students’ perceptions of the instructional videos
and other learning methods were surveyed using an online questionnaire.
In total, 445 of 640 students (69.5% of the cohort)
used the instructional videos. Of those students, 134 (30%) answered
the questionnaire. Of this group, 88.9% rated the instructional
videos as very helpful (49.6% as extremely helpful). An ANOVA
revealed a significant difference between various learning materials in
terms of helpfulness. Post hoc analysis showed that instructional videos
were perceived as the second most helpful learning material after
“self-execution and feedback.”
The study revealed that students use instructional videos
frequently and appreciate them as an extra tool for effective studying.
Ultraschall-gezielte Botulinumtoxin-Therapie in der Neurologie: etablierte Indikationen und Techniken
Authors: Walter Uwe 
Published: November 2019

ZusammenfassungBotulinumtoxin (BT) wird in der Neurologie eingesetzt zur Behandlung von Erkrankungen mit Muskelhyperaktivität, wie Dystonie, Spastik und Zerebralparese, muskulär bedingten Nervenengpass-Syndromen, sowie von Erkrankungen mit Hyperaktivität exokriner Drüsen.Mittels Ultraschall (US) kann die gesamte Prozedur der BT-Injektion in oberflächennahe Muskeln und Drüsen in Echtzeit visualisiert und geführt werden. Die Ergebnisse verschiedener Studien sprechen dafür, dass die US-gezielte im Vergleich zur konventionellen Injektionstechnik den Effekt der BT-Therapie verbessert und Nebenwirkungen reduziert. Die US-gezielte Injektionstechnik ist heute etabliert zur BT-Injektion in die Glandula parotis und die Glandula submandibularis bei neurologischen Erkrankungen mit Hypersalivation. Des Weiteren ist die US-gezielte BT-Injektion zu empfehlen bei komplizierten Formen der zervikalen Dystonie sowie bei dystonem Kopftremor, insbesondere zur Injektion der Mm. scaleni, des M. obliquus capitis inferior und des M. longissimus capitis. Die US-gezielte BT-Injektion ist Standard bei der Behandlung spezifischer Unterarmmuskeln (z.B. einzelner Fingerflexoren), wenn deren Funktionalität von Bedeutung ist, insbesondere bei tätigkeitsassoziierten Dystonien und bei milder Spastik. Die US-gezielte Injektionstechnik ist sinnvoll bei Therapie bestimmter Beinmuskeln. In dieser Übersicht werden die Technik und die häufigen neurologischen Indikationen der US-geführten BT-Injektion vorgestellt.

Published: November 2019

Abstract
Objective We investigated direct effects of a therapeutic growth hormone dose on lipolysis, glucose and amino acid metabolism.
Methods This crossover microdialysis trial involved six healthy male volunteers receiving single subcutaneous injections of both growth hormone (0.035 mg/kg) and placebo (0.9% sodium chloride). The investigation comprised three test days with standard diet. The first day served for adaptation, the second and third one for determining study data during 9 night hours with or without growth hormone. Abdominal subcutaneous microdialysate and blood were continuously collected and forwarded to a separate room next door where hourly taken samples were centrifuged and frozen until analysed.
Results Growth hormone achieved the peak serum level after 3 h followed by a plateau-like course for the next 6 h. Glycerol in microdialysate started to rise 2 h following growth hormone injection achieving significance compared to placebo after 9 h (P<0.05). Serum glycerol increased 4 h after growth hormone administration achieving significance after 6 h (P<0.05). Glucose and amino acid concentrations showed neither in microdialysate nor in serum significant differences between growth hormone and placebo. Serum values of insulin and C-peptide revealed no significant difference between growth hormone and placebo.
Summary and Conclusion As the result of a high single subcutaneous dose of GH, persistent lipolysis can be shown in continuously collected microdialysate and blood, but no indication for gluconeogenesis or protein anabolism.
Orconstructions
Authors: Ariel Mira 
Published: November 2019

AbstractUtterance interpretation involves semantically specified codes and context-based pragmatic inferences, which complement each other. The goal of this paper is to demonstrate the very complex relation between a subset of codes, Goldbergian constructions, specifically ones centering around ‘alternativity’, and pragmatic inferences. I analyze a variety oforconstructions and sub-constructions, emphasizing not only the role of coded constructions on the one hand, and of inferences, on the other hand, but also of cues, namely, linguistic forms that bias towards a specific interpretation, although they do not encode that interpretation. The synchronic variability with respect to the relative contribution of code, inference and cue reflects a grammaticization cycle whereby codes (here constructions) are routinely enriched by inferences, often supported by cues, which in turn may evolve into new codes (here sub-constructions).
Two-echelon Inventory Deploy In Advance Selling
Authors: Dong Ya , Zhao Qilan 
Published: November 2019

Abstract
Advance selling has been chosen and accepted by more and more e-commerce companies and consumers, but it’s common for consumers to cancel orders in advance. Compared to spot sales, advance selling owns a longer order delivery time. The purpose of inventory allocation is to meet the economic needs and time preferences of consumers in different situations, to maximize profits and enhance the competitiveness of e-commerce companies. This dissertation dissects the consumer demand in terms of consumer utility and Regret Theory, and it dives into consumer time satisfaction in combination with the delivery time of orders and the expected delivery time of consumers. The dissertation builds a two-echelon inventory allocation model for inventory distribution. By analyzing the model and the example, the following conclusions can be drawn: inventory downward of e-commerce enterprise can significantly improve consumer time satisfaction. The greater inventory-sink of each terminal distribution station, the more satisfied consumers are. Meanwhile, inventory downward cannot be improved by continuing to increase its amount when the time satisfaction reaches a certain level. E-commerce enterprises should adopt different inventory allocation schemes according to diverse purposes.

And with the impact of rib columns number on the average size of ribs is gradually reduced. The displacement, stress and strain decreasing trend gradually slowing down. Combined with the actual construction environment and economic considerations can provide theoretical support for the rib column design of the real case structure.
Single Underwater Image Enhancement Based On UCIQE
Authors: Ao Jun , Zhang Mingming , Ma Chunbo 
Published: November 2019

Abstract
In order to deal with the problems of low contrast and color distortion of underwater images, a single underwater image enhancement method based on UCIQE is designed in this paper. It estimates background light intensity by a quad-tree search algorithm and divides the image into many blocks based on the assumption that the transmittance of local blocks is equal. The objective function of each block is composed of UCIQE and the information loss function, and the transmittance is obtained at maximum value of the objective function. The global optimization of the overall transmittance image is carried out by using the guided filter. Experimental results demonstrate that this method can effectively solve the problem of color deviation and blur of underwater degraded images.

Authors: Jianlei Han , Qingzhong Ming , Changwen Xie , Pengfei Shi , Xiaotong Wu , Keying Yin 
Published: November 2019

Abstract
The virtual online community has become an important platform for tourists to share their experience and perception of the tourist spots. Due to the originality without artistic processing, the content generated by internet users makes the information relatively more authentic and trustworthy. By taking Xishuangbanna as a typical area of border ethnic areas for case studies, the paper crawls tourists comments from Ctrip.com, through text mining, and quantitatively analyzes the high-frequency words regarding tourists’ experience and their perception in Xishuangbanna, covering such aspects as semantics, time series, value dimension, multi-dimensional scale, in order to understand the travel experience demand and market development trend in border ethnic areas. It is found that tourists have a relatively good perception of their travel experience in Xishuangbanna, and the overall evaluation of travel experience and perception is mainly positive; the product perception diversity is obvious; there are significant differences in various types of tourism elements perception, and tourists have formed clear and typical perception groups in terms of their travel experience in Xishuangbanna. Accordingly, this paper suggests that three ‘trump cards’ should be played for the future development of tourism in Xishuangbanna. Specifically, consumers for night tourism should be nurtured. The tourism elements system should be optimized, and the quality of tourism service facilities be improved. Meanwhile, market supervision should be strengthened and the level of travelling convenience be enhanced so as to optimize the tourists’ experience and perception of border tourism.
Partially connected hybrid precoding design for millimeter wave MIMO systems
Authors: Zheng Xinglin , Wang Yue , Liu Wei 
Published: November 2019

Abstract
To solve the problem of spectral efficiency and energy efficiency of hybrid precoding in millimeter-wave communication system. This paper considers alternately using the minimization framework to increase beamforming gain. However, such framework because the radio frequency domain phase modulation network are using phase shifters, which result in non-convex constraints, and known solutions suffer from high computational complexity. Before using the alternate minimization architecture, it is proved that the phase angle of the ordered right singular vector of the channel matrix can be used to initialize the analog precoder, and hence, the complicated optimization procedures used to search the near-optimum analog precoding matrix can be avoided. In addition, the antenna array response vectors at the transmitter are not required. The simulation results show that the performance of the proposed algorithm is better than the traditional partial-connected algorithm and the complexity is lower, especially in the case of high signal-to-noise ratio.
RETRACTED: Influencing Factors of Agricultural Insurance Demand under the Background of Big Data
Authors: Yuping Wang 
Published: November 2019

Abstract
The development status of agricultural insurance in China, the overall coverage of crop insurance and forest insurance is still less than 60%. Except for wheat, rice and corn crops, the coverage of other crops is relatively low. The coverage of aquaculture insurance is low, especially the penetration rate of important animal products such as fat pigs and dairy cows is less than 25%. Emerging products such as weather index insurance, price index insurance and facility agricultural insurance are still in the initial stage of exploration. The supply of agricultural products with local, industrial and functional characteristics is insufficient and it is difficult to meet the diversified protection needs. The investment in insurance product development is relatively insufficient, which reflects the insufficient supply of agricultural insurance products and services in China. This paper comprehensively studies and discusses it.

Published: November 2019

Abstract
There have been growth demands for two-finger end-effector in agricultural and industrial because of the simple structure and control strategy. This paper reviews the human grasp behaviour, design of two-finger end-effectors, and research on self-adaptive stable grasp control. Human grasp behaviors such as grasp pattern and self-adaptive grasp provide useful information for humanoid two-finger end-effector. Most of the two-finger gripper and intelligent grasp strategy are focused on the stable grasp for regular object at present time. The self-adaptive stable grasp strategies of two-finger end-effector are presented by force-closure grasps strategy, contact stability grasp strategy and grasp synthesis strategy. Self-adaptive stable grasp synthesis strategy should consider the influence factor include geometric of contact surface and interaction of center of mass. In addition, the future work on two-finger self-adaptive stable grasp for 3D irregular object and 3D soft object is also reviewed.
An Environmental Cost Value Model Based on Dynamic Neural Network Prediction
Authors: Tan Yaxin , Zuo Jiankai , Chen Jiatong 
Published: November 2019

Abstract
Ecological environment, which human beings depend on for survival, constantly provides us with various benefits. The exploitation and use of land by human beings will cause damage to the ecological environment. More seriously, the loss caused by environmental damage is often not concluded in the cost. Therefore, it is necessary to establish a complete environmental cost assessment model. By analyzing the value of ecosystem service and combining with previous studies, we proposed a new model—“DIP- PRSC model”—for evaluating the environmental costs of land projects. This model creatively divides environmental costs into fixed costs and floating costs. We use 16 indicators to measure the cost of each part of the model. We applied the model to the construction of the Rondônia highway in the Brazilian to verify the validity of the model, using NAR neural network to predict the cost of each part of the DIP model, and put the predicted cost into the DIP model to calculate the total cost. The results show that the environmental cost of the land project will continue to rise in the next eight years.
A YOLOv3-based non-helmet-use detection for seafarer safety aboard merchant ships
Authors: Zhong Mingliang , Meng Fei 
Published: November 2019

Abstract
International shipping industry undertaking more than 80% global trade volume, is indispensable to the world’s economy and development. Seafarers, which are an important part of shipping, mainly engage in safe navigation and good maintenance of ships. However, they are prone to expose themselves to occupational accidents and injuries, especially fatal trauma on the head due to non-helmet-use behaviour. Wearing a safety helmet can effectively reduce the risks resulting in head injuries. Despite the vital role of safety helmet, many seafarers tend to take off their helmet because of discomfort caused by weight and high temperature in engine room or deck. To improve the ship’s safe operation and prevent the loss of life at sea, this paper proposed a state-of-the-art method based on YOLOv3 model for automatic and real-time detection of non-helmet-use behaviour. The experimental results showed that the detection method can run real-time under ship’s video surveillance and precisely detect the non-helmet-use behaviour with low miss rate.

Published: November 2019

Abstract
The similarity of binary code is widely used in code copyright protection, vulnerability mining, malicious code analysis and etc. In this paper, we proposed a method for measuring/evaluating the similarity of two binary files based on software genes. Some of Natural language processing methods were introduced into program semantics analysis, including word2vec and doc2vec models to generate assembly instruction embeddings and gene semantic embeddings. Then the longest common subsequence method was applied to evaluate the software similarity. Experiments show that our method can effectively evaluate the similarity of binary files.
