The theory and practice of heating quality steel ingots
Authors:   University Politehnica Timisoara, Faculty of Engineering Hunedoara, Ilca Ioan
Published: September 2022

In the process of hot–metal working under the pressure, the heating of the metallic material has a decisive influence upon the quality of the resulted products. On choosing the heating method it has to be taken into account the properties of the metallic material and the kind of its further processing. A performing method for establishing the heating regime of quality steel is proposed. This method is based on the mathematical theory of thermal conductivity and takes into account the nature of steel and the technological processing factors. The analytical determination of the thermal stress is based on the theory of elasticity. Therefore, in order to solve the heat transmission’s equations, the obtained results do not correspond, in sufficient measure, with practical data. These results may be considered only as a first approximation that requires to be corrected using the experimental data. It is not intended the examination of different kinds of stress that appear in the steels’ heating processes. Is mentioned only that the thermal stress are dangerous in the case of steels with low plasticity and heterogeneous structure, in the presence of the non-metallic inclusions, gas bubbles, films, segregations, holes in the crystalline network etc. The steel’s inhomogeneity will result in uneven distribution of the stress, and sometimes, at concentration of the tension in certain parts of the ingots. At heating of these ingots, it is possible to the destruction of the integrity, if the stress value becomes comparable with the limit of the resistance, before the temperature from the central part exceed the limit of elasticity (500-5500 C). It is known that the steel have sufficient elasticity till the interval 500-5500 C, over which, practically, can be found in the plastic status. Therefore, thermal stress should be taken into consideration in the heating process, in the interval of 0-5000 C, especially in the case of steels with low plasticity. The size and the repartition of the thermal stress depend on the heating conditions, thermophysical and mechanical properties of the steel, the shape and size of the ingots. The work proposes to determine the thermal stress depending on the heating speed, on the basis of the parameters resulting from the experimental research, in order to optimize the heating of the austenitic stainless steel ingots

Published: September 2022

In today's era, every electrical and electronic device is connected very intelligently. These electronic devices like sensors, RFIDs, actuators are becoming an important part of the structure. It is required to connect to the internet. Internet is used in every aspect of daily life. There are drastic changes in the usage of the most demanding and useful technology known as the Internet of Things (IoT). In this field, IoT has been shown one of the important which connect various physical objects with the internet with unique identification. Billions of objects are enabled with the internet and interconnected with each other to interface with Human-to-Machine or Machine-to-Machine to take decisions of data transaction without human involvement. This internet enables devices connected to our social life which is terme as Social Internet of Things (SIoT). Hence we can say SIoT is an expansion IoT. People and things are connected with social networks which are known as Human to Things (H2T) interactions. Some of the devices are authentic and some are suspicious. The essential utilization of services within SIoT makes a secured network closely rely on origin of services (Service provider) and services accesed by end terminal (Service requester). Due to a lack of trust technologies, trust SIoT is still not so much popular in the market as demanding technology for the researcher and developer. Device owners are worried about sharing the data or receiving any information. Therefore, trust devices are required to identify in the connected network..Hence minimization of risk and uncertaintity within the system are analyse by the degree of trust for Particular Trust Management System(TMS).Trust and Trustworthiness are novel fields in social networking environment clearlify by investigating the research article under SIoT. In present paper, our contribution starts with the introduction and then is further fragmented in three phases.The first phase represent the basic of trust and SIoT. Second phase categorizes the trust management solutions from the literature review. The third phase identifies and discuses issues, challenges and requirement in current scenario of SIoT and also depicts how developing trust and trustworthiness among social devices interaction as challenging task.
Assessment of Network & Processor Virtualization in Cloud Computing
Authors: Rashid Mahmood  , Muhammad Imran  , Sayyid Kamran Hussain
Published: September 2022

Cloud Computing is an emerging field in applied computer science. Cloud computing depends on virtualization, where a sole physical resource is virtualized into numerous virtual resources. Resources that are being virtualized include physical storage, processing units, volatile memories, network, and further physical resources. Processor and network virtualization offer several advantages like lessening hardware cost, energy consumption, and the human struggle for administration and management of resources. In this article, the primary concentration was on the evaluation and assessment of network virtualization between different cloud computing hypervisors and to contrast their evaluated results. This comparison is based on a few experiments performed on Citrix XenServer, Microsoft Hyper-V, and VMware vSphere hypervisors. XenServer uses Open vSwitch for its network virtualization whereas Hyper-V and vSphere use Microsoft network virtualization and vSphere switch for managing their network virtualization respectively. We have found that virtual networks are further scalable and secure than physical networks. We can assign multiple virtual interfaces or connections to a single virtual machine. In light of various experiments, in which we have compared non-virtualized with virtualized scenarios, for all these above-mentioned hypervisors, we found out that we can use virtual networks with and without VLAN Tags or VLAN Ids. Hyper-V provides further flexibility and options regarding VLAN Tag in comparison with XenServer or vSphere. We have also found that XenServer and vSphere give us extra network throughput in comparison with Hyper-V in terms of TCP and UDP whereas Round Trip Time (RTT) in the virtual network of all hypervisors are high in comparison with the non-virtual environment. Network CPU usage is also measured and found that vSphere and XenServer together consume more CPU during network activity in comparison with Hyper-V. We also found that processor virtualization did not majorly result from the average schedule time in comparison with a non-virtualized machine. We consequently conclude that in general a small reduction in the performance, in the case of virtualization is insignificant as compared with the advantages we get from virtualization when using cloud hypervisors. For the application of virtualization, this work will motivate to set up of data centers using a virtualized environment.

A Novel Algorithm for Moving Target Detection
Authors: Muhammad Waqas  , Muhammad Imran  , Atif Raza Zaidi
Published: September 2022

The approach for this project is simple. For the detection of moving, we had employed the method of image subtraction and absolute frame differencing of consecutive frames coming from the static camera for making a robust approach for signature locking of the detected target. Through the image subtraction technique, we extract the coordinates of the moving target from the image and to a designed mechanical system that can operate the gun. A red signature is accurately a red object in the real-time video. The reason behind a red object is that a thermal camera detects the object on the base of the temperature gradient and the thermal camera detects an aircraft in the form of a red object. The thermal camera is so expensive that why we chose the visual camera and selected red object as a signature so that this algorithm is also capable to detect and track a thermal target from the thermal camera. And after detecting the coordinate of the required target sent to our gun barrel to shoot that target for future enhancement. There exists a lot of applications for our project, especially from a security point of view. This thesis explained how to detect and track red targets in a live video. There are distinctive ways to deal with recognizing the red/warm shading in each edge. One of these prevalent methodologies incorporates the change of the entire RGB outline into comparing the HSV (Hue-Saturation-Value) plane pursued by extraction of pixel esteems just for red. One can pick a range that mirrors every single existing shade of red to distinguish and separate all hues in the frame.

Spiral fractures in the distal third of the femoral shaft in elderly treated with antegrade nailing and STABLE-LOK Nut®: case report
Authors: Quarta Davide , Cianforlini Marco , Politano Rocco , Gigante Antonio
Published: September 2022

We present the case of a 90-year-old woman with a traumatic a spiral distal femur shaft fracture. The patient underwent surgery for reduction and fixation of the fracture with an intramedullary antegrade nail. The patient was re-evaluated during the course of a clinical and radiographic follow-up. There were no infectious problems and the patient was able to resume normal activities for her age. Distal femur shaft factures can result from high-energy trauma in young patients or from a fall or minor trauma in the elderly. They are always challenging for the surgeon, especially in terms of choosing the correct fixation method. Early reduction and stable fixation with a mini-invasive approach are essential for a good outcome in elderly patients.
Mind the Proportionality Gap!
Authors: Audenaert Nele
Published: September 2022

Although it is not a secret that the precise implications of the proportionality principle in criminal law matters are still subject to debate, up until now, this has not been perceived as problematic. However, analysis reveals that the poor framing of the proportionality principle has some extreme negative consequences in transnational (EU) settings. The vague and inconsistent interpretation of the proportionality principle could not only result in disproportionate sentences, but could also give rise to an infringement of the equality principle. This contribution aims to stress and challenge these insufficiencies of the theoretical framework by exploring the gaps that urgently need to be dealt with. Furthermore, some possible solutions are thoroughly examined.
The Protection of Age-related Vulnerable Persons in Criminal Proceedings under German Law – An Examination Measured Against the European Guidelines
Authors: Zink Sarah
Published: September 2022

Population ageing is a phenomenon that affects our societies, with both the number and proportion of older people growing across Europe. This impacts the legal capacity of vulnerable adults, who face challenges and difficulties in protecting their rights, defending their interests and accessing justice, both in national and in cross-border situations. In cross-border situations, for instance, in the case of citizens residing in a State other than that of their nationality, these existing difficulties may be exacerbated by additional obstacles with respect to language, representation or access to the judicial system and to public services in general. Those needs have been identified by the European Union. On 27 November 2013, the Commission adopted a Recommendation on procedural safeguards for vulnerable persons suspected or accused in criminal proceedings.1 The aim of the Recommendation is to encourage Member States to strengthen the procedural rights of all suspects or accused persons who are not able to understand and effectively participate in criminal proceedings due to age, their mental or physical condition or disabilities (‘vulnerable persons’).

On 27 May 2021, the Council of the European Union invited the Member States to ensure the full implementation of the existing provisions.2 Consideration is being given to whether further action should be taken.

This article assesses the extent to which the existing German criminal procedure law currently meets the standards for protecting older suspects and accused persons identified by the Recommendation of the Commission. By establishing minimum rules on the protection of procedural rights of suspects or accused persons in this field, the trust of Member States in criminal justice systems of other Member States can be strengthened and, thus, mutual recognition of decisions in criminal matters can be improved. In order to achieve the establishment of minimum rules, it is necessary to create a common understanding of the systems of the other Member States, which this article seeks to achieve. It also intends to provide insight into the German system that would be needed to decide, together with a consideration of the systems of the other Member States, whether further legislative action at the level of the European Union, in particular in the form of a Directive, is required.
The Liberal Arts and Virgil’s Aeneid: What Can the Greatest Text Teach Us?
Authors: Hejduk Julia D. ,   Philosophy Documentation Center
Published: September 2022

As the classic of classics and the bridge between pagan antiquity and the Christian era, Virgil’s Aeneid stands at the center of the humanities’ Great Conversation. Yet this poem of Empire, with its flawed hero and its ambivalence toward divine and temporal power, raises more questions than it answers about the nature of human history. The epic’s true moral complexity, mirroring the insoluble conundrum that is human life, makes it especially relevant in an era whose political polarization resembles civil war. Reflecting on centuries of readers’ deeply personal relationships with the Aeneid, this article discusses how even today the “greatest text” can provide companionship and inspiration on our life’s journey.
Commonwealth of Portorico as the basis of a proposal for a solution to the Kosovo conflict
Authors: Šarac Jovan , Opačić Ana
Published: September 2022

According to the authors, the resolution of conflicts, such as the one in Kosovo, which has a long and complex history, must undoubtedly start from the real situation, while respecting the interests of all stakeholders and the balance of power domestically and internationally. In order to solve this problem, various ideas have been presented so far, mainly based on the experience of multicultural states that have used various contractual, constitutional and legal mechanisms to resolve conflicts of this kind. As possible models, the authors suggest the status of the Åland Islands, the Italian provinces of Trentino - South Tyrol and the Commonwealth of Puerto Rico. All three proposed models are a reflection of historical, legal-economic, sociological and cultural circumstances, so any consistent application by copying the solution to the status of Kosovo and Metohija would be doomed to failure from the very beginning. According to the author, starting from the real situation, and respecting the interests of all stakeholders, it is evident that the Puerto Rican Commonwealth model, with certain loans from the other two models and respect for local specifics, could be applicable to the Kosovo situation. According to this model, the Republic of Serbia would retain its sovereignty over Kosovo, while Kosovo would be recognized with limited international legal subjectivity, without membership in the United Nations and other important international organizations. The authors especially emphasize the importance of the model of South Tyrol, which could be a good starting point for regulating the status of the Serbian community, which in cooperation with the Brussels Agreement, called "Community of Serbian Municipalities" would have the status of autonomy within autonomy.

Authors: Vasic Milos , Brzakovic Miodrag , Stanojevic Nada
Published: September 2022

The subject of this paper is a complementary area consisting of management systems (QMS) and information systems (IS), i.e., the theoretical and practical need for their parallel design, development, implementation and operation. Companies are increasingly concerned with managing the quality of their products and services in accordance with international standards. Designing a quality management system requires the intensive participation of managers and employees who perform analysis and reengineering of business processes and accompanying procedures. Very similar requisites and tasks characterize the design of a company's information system, but these two endeavours are most often implemented as separate projects, handled by different teams, equipped with unrelated methodologies. Within the scope of this paper, the author's ambition was to establish a model of synergistic connection of the information system and the quality management system through the establishment of a Quality management system suitability function and check to what extent the definition of common databases, integrated data model and information model confirms or refutes the hypothesis that the integration of QMS and IS contributes to better overall business results and individually improves each of the connected systems.
Application of Unsteady Vortex-Source Lattice Method on Supercavitating Propellers
Authors: Kudo Tatsuro , Kinnas Spyros A.
Published: September 2022

A computational method (HPUF-3A) for the prediction of unsteady propeller blade sheet cavitation is applied to the analysis of supercavitating propellers in steady flow. The method is incorporating a vortex and source lattice scheme.

To allow for the treatment of very long supercavities, improvements were introduced in the cavity extent iteration algorithm and in the force calculation procedure. The modeling of the separated flow behind trailing edges with non-zero thickness (very often the case for supercavitating blade sections) was also included.

Results of this method are extensively validated and compared with those of another method, as well as with measurements from a supercavitating propeller experiment.

Authors: Nehrling Bruce C. , Shaughness James J. , Compton Roger H.
Published: September 2022

Over the past three years, the Naval Academy Hydromechanics Laboratory (NAHL) has been investigating the behavior of both intact and damaged ship models in the presence of moderate and severe wind and waves. This paper describes the design, fabrication, calibration, and use of the wind generation system developed for this experimental study. This modular wind generation system consists of up to four centrifugal fan sets suspended across the towing tank on a system of trusses. The discharge of each fan set is vectored (vertically) by adjustable louvers and throttled by means of an internal baffle. Wind velocity is measured at selected locations by a set of miniature vane anemometers. This collection of anemometers is used to map the towing tank's wind field longitudinally, vertically and transversely. Significant differences exist in the spatial distribution of the wind velocity and its quality between the NAHL wind field, theoretical assumptions, and the real world. These differences are described. In addition, decisions, observations, and ramifications regarding the scale modeling of a wind field, in conjunction with pragmatic model testing in a conventional towing tank, are discussed.

A new empirical model is proposed for predicting particle kinematics and forces on a structure affected by measured nonlinear irregular waves. The predicted and measured data are in excellent agreement. Application of the model seems to be diverse and it is envisioned that the technique may be employed for excellent simulation of nonlinear responses including ringing of a coupled TLP in steep nonlinear irregular waves. The technique for generation of realistic steep nonlinear irregular waves in a wave tank is a pressing need.
Asymmetrical SWATH Lift and Drag Measurements
Authors: Cohen Stuart B.
Published: September 2022

Tests of geometrically symmetrical SWATH pontoons mounted asymmetrically with respect to the struts showed strong lift coefficients resembling those of a cambered foil or flat plate at an angle of attack. Two such demi-hulls were tested as a complete SWATH and showed more drag than the increase due solely to strut interaction. This foil-like interaction may explain the large increase in drag seen in recent asymmetrical pontoon ("golf-club") model tests.

Outdoor Testing of Large Models and Associated Developments for Radio-Controlled Maneuvering Experiments
Authors: Rossignol Grant
Published: September 2022

This paper discusses an improved capability for conducting maneuvering tests of large models and presents an example of a radio-controlled surface model maneuvering experiment, conducted both indoors in a test basin and outdoors in a lake. Recent requirements of various experiments at the Naval Surface Warfare Center, Carderock Division (NSWCCD), formerly the David Taylor Model Basin, have caused models to be constructed that are much larger than in the past. These large models have significantly limited the maneuvers that can be conducted in the space of the Saunders Maneuvering and Seakeeping (MASK) Facility, causing many maneuvers for large models to be conducted outdoors in local lakes. The results presented here were obtained indoors in the MASK and outdoors 323 at Lake Needwood in Rockville, Maryland. This paper also discusses new developments in the instrumentation used with current and future radio-controlled model experiments.

Pljučna hipertenzija je pestra bolezen, ki pomembno poslabša napoved izida pri bolnikih, zato stremimo k zgodnjem odkrivanju, saj določene podrazrede pljučne hipertenzije lahko učinkovito specifično zdravimo. Ključna preiskava, s katero potrdimo ali ovržemo diagnozo pljučna hipertenzija, je desnostranska srčna kateterizacija. Poleg invazivno izmerjenega tlaka v pljučni arteriji med desnostransko srčno kateterizacijo merimo minutni srčni iztis, opredelimo, ali gre za t.i. predkapilarno ali pokapilarno (oz. kombinirano) pljučno hipertenzijo, ter pri izbranih bolnikih izvajamo test vazoreaktivnosti in/ali test obremenitve s tekočino. Ultrazvočna preiskava srca je sicer bolj dostopna, enostavna in manj invazivna preiskava za odkrivanje pljučne hipertenzije, vendar nam lahko poda le verjetnost, da hipertenzija obstaja. Zato se uporablja le kot presejalna metoda za odkrivanje pljučne hipertenzije. Pri utemeljeno povečanem tveganju za pljučno hipertenzijo pa za postavitev diagnoze in spremljanje učinkovitosti zdravljenja redkih oblik pljučne hipertenzije vedno opravimo desnostransko srčno kateterizacijo. Najpogosteje se pljučna hipertenzija pojavlja pri bolnikih z boleznijo levega srca ali pljučno boleznijo. Redkejši obliki pljučne hipertenzije, pri katerih je v ospredju remodeliranje pljučnega žilja, sta pljučna arterijska hipertenzija in kronična trombembolična pljučna hipertenzija. Pri slednjih dveh so zelo učinkoviti specifični ukrepi, kot so uvedba specifičnih zdravil za pljučno hipertenzijo in pri kronični trombembolični pljučni hipertenziji na prvem mestu pljučna endarterektomija in/ali balonska dilatacija pljučnih arterij. Vse to pomembno izboljša napoved izida bolezni in kakovost življenja bolnika. Na Kliničnem oddelku za pljučne bolezni in alergije Univerzitetnega kliničnega centra Ljubljana od septembra 2018 redno, tedensko, opravljamo desnostranske srčne kateterizacije za diagnosticiranje redkih oblik pljučne hipertenzije, spremljanje učinkovitosti zdravljenja in v postopku predpriprave na presaditev pljuč.
A Machine Learning Approach for Predicting Human Preference for Graph Layouts
Authors: Cai Shijun , Hong Seok-Hee , Shen Jialiang , Liu Tongliang
Published: September 2022

Understanding what graph layout human prefer and why they prefer such graph layout is significant and challenging due to the highly complex visual perception and cognition system in the human brain.
In this paper, we present the first machine learning approach for predicting human preference for graph layouts.
Specifically, we propose a CNN-Siamese-based model to predict human preference from a pair of different layouts of the same graph.
We employ a transfer learning method to overcome the insufficiency
of the available ground truth human preference experiment data for training deep neural networks.
Specifically, we exploit the quality metrics, which are correlated to human preference on graph layouts, to pre-train our model. Then, we fine-tune the model using the ground truth human preference experiment data.

Experimental results using the ground truth human preference data sets show that our model M+HP can successfully predict human preference for graph layouts, achieving the average test accuracy of $92.28\%$ for large scale-free and mesh graphs.
To our best knowledge, this is the first approach for predicting qualitative evaluation of graph layouts based on the ground truth human preference experiment data.
Moreover, comparison experiments show that our model outperforms a simple baseline model and a previous Siamese-based model, demonstrating the importance of using graph layout images and the CNN-based model for predicting human preference.
Maximal origami flip graphs of flat-foldable vertices: properties and algorithms
Authors: Hull Thomas , Morales Manuel , Nash Sarah , Ter-Saakov Natalya
Published: September 2022

Flat origami studies straight line, planar graphs $C=(V,E)$ drawn on a region $R\subset\mathbb{R}^2$ that can act as crease patterns to map, or fold, $R$ into $\mathbb{R}^2$ in a way that is continuous and a piecewise isometry exactly on the faces of $C$. Associated with such crease pattern graphs are valid mountain-valley (MV) assignments $\mu:E\to\{-1,1\}$, indicating which creases can be mountains (convex) or valleys (concave) to allow $R$ to physically fold flat without self-intersecting. In this paper, we initiate the first study of how valid MV assignments of single-vertex crease patterns are related to one another via face-flips, a concept that emerged from applications of origami in engineering and physics, where flipping a face $F$ means switching the MV parity of all creases of $C$ that border $F$. Specifically, we study the origami flip graph $\rm{OFG}(C)$, whose vertices are all valid MV assignments of $C$ and edges connect assignments that differ by only one face flip. We prove that, for the single-vertex crease pattern $A_{2n}$ whose $2n$ sector angles around the vertex are all equal, $\rm{OFG}(A_{2n})$ contains as subgraphs all other origami flip graphs of degree-$2n$ flat origami vertex crease patterns. We also prove that $\rm{OFG}(A_{2n})$ is connected and has diameter $n$ by providing two $O(n^2)$ algorithms to traverse between vertices in the graph, and we enumerate the vertices, edges, and degree sequence of $\rm{OFG}(A_{2n})$. We conclude with open questions on the surprising complexity found in origami flip graphs of this type.

Background

Android is the most widely used operating system all over the world. Due to its open nature, the Android operating system has become the target of malicious coders. Ensuring privacy and security is of great importance to Android users.

Methods

In this study, a hybrid architecture is proposed for the detection of Android malware from the permission information of applications. The proposed architecture combines the feature extraction power of the convolutional neural network (CNN) architecture and the decision making capability of fuzzy logic. Our method extracts features from permission information with a small number of filters and convolutional layers, and also makes the feature size suitable for ANFIS input. In addition, it allows the permission information to affect the classification without being neglected. In the study, malware was obtained from two different sources and two different data sets were created. In the first dataset, Drebin was used for malware applications, and in the second dataset, CICMalDroid 2020 dataset was used for malware applications. For benign applications, the Google Play Store environment was used.

Results

With the proposed method, 92% accuracy in the first data set and 92% F-score value in the weighted average was achieved. In the second data set, an accuracy of 94.6% and an F-score of 94.6% on the weighted average were achieved. The results obtained in the study show that the proposed method outperforms both classical machine learning algorithms and fuzzy logic-based studies.

Authors: Akhmetov Iskander , Mussabayev Rustam , Gelbukh Alexander
Published: September 2022

The extractive text summarization (ETS) method for finding the salient information from a text automatically uses the exact sentences from the source text. In this article, we answer the question of what quality of a summary we can achieve with ETS methods? To maximize the ROUGE-1 score, we used five approaches: (1) adapted reduced variable neighborhood search (RVNS), (2) Greedy algorithm, (3) VNS initialized by Greedy algorithm results, (4) genetic algorithm, and (5) genetic algorithm initialized by the Greedy algorithm results. Furthermore, we ran experiments on articles from the arXive dataset. As a result, we found 0.59 and 0.25 scores for ROUGE-1 and ROUGE-2, respectively achievable by the approach, where the genetic algorithm initialized by the Greedy algorithm results, which happens to yield the best results out of the tested approaches. Moreover, those scores appear to be higher than scores obtained by the current state-of-the-art text summarization models: the best score in the literature for ROUGE-1 on the same data set is 0.46. Therefore, we have room for the development of ETS methods, which are now undeservedly forgotten.

Authors: Tjunarwi Alyni , Setiawan Dwi
Published: September 2022

This study analyzes a movie entitled Mona Lisa Smile. It is interesting that the movie contains the message about women’s liberation movement reflected through the value transformation done by one of the characters, Betty Warren, which is why we decided to emphasize on the transformation as our main focus. We attempt to reveal the process of Betty Warren’s value transformation by applying two concepts, which are the concept of Angel in the House and the concept of New Woman. We find out that Warren’s experience of value transformation goes through several stages, which are from believing in her old values, going against the new modern values, finding disappointment toward her old values, then having a conflict within herself, and as the result, starting to consider and absorb the new values. The analysis leads to the fact that patriarchal values can be so strong because sometimes, women themselves are subconsciously acting as the agents.
The Portrayal of Jesus in the Film Son of God
Authors: Suryonugroho Samuel Anggi
Published: September 2022

This thesis discusses how Jesus is portrayed as a New Messiah in the film Son of God. In the Son of God, Jesus is completely a different Messiah compared to the most popular concept about Messiah in the first century. Jewish people believed that a Messiah would come with similar characteristics like King David who was strong, gathering a strong army to beat the enemy and set the people free from oppression. By using the theory of Messiah, I would like to analyze how Jesus is portrayed as a new Messiah. Jesus came as a humble man in a poor family. During his ministry, he gathered low-profile disciples because his intention was not to build an earthly kingdom but the divine one. He served the people by performing miracles by his own authority to show that he had divine nature. Jesus also experienced suffering and death in order to save the people from eternal death. The last, Jesus resurrected from death proving that all of his Messianic claims were true and he had divine nature.Keywords: Messiah, the Davidic Messiah, Jesus

Authors: Rachman Regina Carissa
Published: September 2022

This creative work is in five children’s picture book format for the target of age five to nine and the topic focuses on children’s anxiety. My stories will be in low fantasy genre, where the anxiety in each story has various forms. The main theme of my stories is to show that what anxiety produces negative thoughts that are not based on reality. To show how children can have anxiety, I use Cognitive Distortions theory, and to show how children can cope with their anxieties, I use Cognitive Behavioural Therapy (CBT) theory. Each of my stories will be about how anxiety happens to the main character and how the main character solves the problem. From the research I did, I found that anxiety happens to children and it produces negative thoughts that are later proven to be untrue. With CBT, children can also learn how to cope their anxieties by self-monitoring their own emotions and turn negative thoughts into positive ones. Keywords: Children, anxiety, cognitive distortions, cognitive behavioural therapy
