Application of Scrum Maturity Model: A Case Study in a Telecommunication Company

Digitalization and internet penetration force telecommunication companies to perform a transformation to survive, to face competitions, and to gain opportunities. PT XYZ is a telecommunication company that has introduced a new leaner and agile working method for digital transformation. The organization is undergoing a transformation to implements an agile approach using a scrum framework. There are two divisions that use scrum that currently plagued with time estimation difficulties and inability to create an agile backlog due to the old change request mechanism. Scrum Maturity Assessment (SMM) is used to measure current scrum practice maturity. The data is retrieved using a questionnaire that was given to two Scrum Master from two divisions which have been implementing Scrum. There are 83 questions derived from SMM assessment questions. SMM assessment indicated the scrum practice is Level 1 (Initial). There are 31.76% of scrum practices in IT division and 36.25% of scrum practices in CS division need to be improved to achieve Level 5 Optimizing. In order to achieve Level 5, we proposed 38 steps and six recommendations which will guide the scrum practice improvement process.

Change Impact Analysis using Python for Java Applications

Software Applications needs to be changed constantly as per the requirements of the user or the client. This phase is known as the maintenance phase of a software application. On an average, the cost of software maintenance is more than 50% of all Software Development Life Cycle phases. The main purpose of software maintenance is to modify and update software application after delivery in order to correct faults, enhance the functionality or to improve performance. When the change request (CR) is received from the client the developers have to work upon the request. If the Change Request requires any modification, the application developers have to identify the risk of modifying the program or application before making the actual change. But there is a high chance of making errors in modifying the existing software. Change Impact analysis (CIA) is one of the error prevention technique. It is the process to find the effect of a change in a software application before the changes are made. By equipping developers with automated CIA tools to identify the risk of modifying the application we can minimize the errors. Impact analysis can be done based on the change request. This paper aims at developing a change impact analysis tool which can be used by the developer during the software maintenance phase. This proposed tool -Strategic Dependency Tracker (SDepTrac) helps the programmer/ developer to know “What part of the program (of a Java application) is impacted if a change is to be made to a particular variable / method / class?” with more accuracy compared to the existing tools. It displays the number of lines affected, classes and methods which are going to be affected, if we perform the requested change by considering the data dependency, control dependency and the semantic dependency. Thus the tool helps the developer to identify the impact set and minimizes the human errors and also saves time during the Maintenance phase.

Risk perception of COVID-19 among Portuguese healthcare professionals and the general population

Risk perception assessment of COVID-19 among Portuguese Healthcare Professionals (HCPs) and the general population (GPop) was evaluated in a snowball sample of 3403 individuals, 54.9% of HCPs believed there was a high probability of becoming infected, in contrast with 24.0% of the GPop (P<0.001) and, in more than a quarter, that this could happen to their family. Regarding prophylactic isolation, more than 70% agreed with its effectiveness. A large proportion perceived that health services were poorly prepared (50.1% GPop vs 63.5% HCPs, P<0.001). Regarding health authorities' communication, about 60% were “moderately” satisfied. The opinion that the pandemic could be controlled in 3–6 months was held by 46.7% of the GPop and 52.8% HCPs (P=0.01).

THE BEGINNING OF A LARGE-SCALE POLITICAL REFORM IN RUSSIA: A NEW TURN IN 2020

The subject. The article is devoted to the analysis of the draft political and constitutional reform that was announced in the last Presidential Address to the Federal Assembly at January 15, 2020.&#x0D; The purpose of the article is to try to predict the positive and negative consequences of changing the legal status of the highest Russian authorities. &#x0D; The methodology of the study includes analysis and interpretation of Presidential Ad-dresses to the Federal Assembly and Russian Constitution as well as dialectical approach and methods of political science. &#x0D; The main results and scope of their application. For a long time there was a clear request for changes in the government, and various expert platforms discussed issues related to changing the Constitution of the Russian Federation, which was adopted at a national referendum in December 1993. &#x0D; On January 15, 2020, Vladimir Putin addressed his 16th message to the Parliament. In ac-cordance with the Constitution, the President of Russia annually addresses the Federal Assembly with a message on the situation in the country and on the main directions of domestic and foreign policy. The last address turned out to be a landmark and historical one, as it announced the main provisions of the upcoming large-scale political and consti-tutional reform in Russia. Heads of constituent entities, members of the State Duma and the Federation Council, Prime Minister and Deputy Prime Ministers, Federal Ministers, heads of Fed-&#x0D; &#x0D; &#x0D; eral bodies, judges will no longer be able to have foreign citizenship or a foreign resi-dence permit. He proposed even more stringent requirements for a candidate for the post of President: no foreign citizenship or residence permit even in the past, as well as per-manent residence in Russia for at least 25 years. The position of the State Council is being strengthened and it is reflected in the Constitution of the Russian Federation as an insti-tution of power in the country. The position of the Federal Assembly is strengthened by the fact that the Parliament is given the right to approve the candidacy of the Prime Min-ister, as well as all Deputy Prime Ministers and Federal Ministers. The status of local self-government and the role of governors in the regions is being raised.&#x0D; The main reason for the reform is the desire to reduce the powers of the President and transfer part of them to the Parliament, so that the next President is no longer endowed with virtually absolute power, and, in turn, can not initiate another reform without the approval of all branches of government.&#x0D; The author of the article identifies the reasons for the political reform and gives forecasts for the future after its implementation.&#x0D; Conclusions. The author links these changes to the upcoming transfer of presidential power after 2024. The reform does not mean the transition of the Russian Federation to a parliamentary republic, since the head of state retains the status of a key figure in the po-litical system, and it is he who has concentrated key functions. Fixing a number of social obligations in the Constitution in terms of salaries and pensions will not have a significant impact on the socio-economic situation.

DERIVATION OF DESCRIPTION FEATURES FOR ENGINEERING CHANGE REQUEST BY AID OF LATENT DIRICHLET ALLOCATION

AbstractComplex products and shorter development cycles lead to an increasing number of engineering changes. In order to be able to process these changes more effectively and efficiently, this paper develops a description model as a first step towards a data driven approach of processing engineering change requests. The description model is systematically derived from literature using text mining and natural language processing techniques. An example of the application is given by an automated classification based on similarity calculations between new and historic engineering change requests.

Umanizzazione delle cure: innovazione e modello assistenziale

The contemporary social context shows a profound need to bring healthcare back to a meeting between the technical-organizational needs of the system and the needs for global understanding of the patient. The passage from the “patient” vision to a “person” perspective is the radical request for paradigmatic and operational change to be implemented to respond to new needs, trends and socio-cultural changes. Recent literature shows that the Newtonian-Cartesian reduction of the human being to biomachine, which still resists the culture and unconscious of many health professionals, is no longer justified from a scientific point of view. The conceptual model, the framework of the most advanced sciences is the holistic one. This model lays the foundations for a better understanding of the functioning of the human being and consequently for a new epistemological and anthropological vision, that of the bio-psycho-socio-cultural network, where interaction with the environmental context influences the feedback of this system. It seems fundamental to start a structured path of synergy between the humanization of care and its gradual implementation, for the improvement of the quality of life of nephrological patients and for a new clinical-assistance background for the health workers who work daily in nephrology, dialysis and transplantation.

Enhancing the Emergency Financing Toolkit—Responding To The COVID-19 Pandemic

The COVID-19 pandemic is taking a human toll and has unleashed a series of shocks on the Fund’s entire membership, creating severe disruption in the global economic and financial system. As a result, many emerging market and developing country (EMDC) members face urgent and unprecedented financing needs, creating significant immediate demand for Fund resources. In order to respond to members’ large and urgent financing needs, the paper proposes to enhance the Fund’s emergency financing toolkit, through a temporary increase in access limits for both the Rapid Financing Instrument (RFI), available to all members, and the Rapid Credit Facility (RCF), available to Poverty Reduction Growth Trust-eligible members only. It is proposed to increase these access limits for a proposed period of six months, which may be extended by the Executive Board. A companion Board paper sets out proposals to accelerate Board consideration of member requests for financing under the RCF and RFI, completion of reviews and requests for changes in access in existing arrangements, and requests for grant assistance under the Catastrophe Containment and Relief Trust.

Streamlining Procedures for Board Consideration of The Fund’s Emergency Financing During Exceptional Circumstances Involving A Pandemic

The COVID-19 pandemic has inflicted an unprecedented shock on the global economy and created an enormous demand for Fund resources. To accelerate processing and approval of members’ requests in such circumstances, the paper proposes measures to expedite Board consideration and approval of requests for purchases and/or disbursements under the Rapid Financing Instrument and/or the Rapid Credit Facility, respectively, completion of reviews and requests for changes in access in existing arrangements, and requests for assistance under the Catastrophe Containment and Relief Trust (CCRT), by shortening the circulation period for Board documents. The paper also proposes extending the use of the shortened circulation period to selected Article IV consultations necessary for use of Fund resources during a global pandemic. Management will also streamline internal procedures to accelerate program processing and reduce the burden on the Fund’s administrative capacity, and will seek the support of creditors to expedite the processing of financial transactions under COVID-19 emergency financing.

Agile Scrum Issues at Large-Scale Distributed Projects

The agile model is a very vast and popular model in use in the software industry currently. It changes the way software is developed. It was introduced in 2001 to overcome deficiencies of software development in a workshop arranged by researchers and practitioners who were involved with the agile concept. They introduced the complete agile manifesto. The agile model has main components that make it more viable for use in well-organized software development. One of these is scrum methodology. The reason for the agile-scrum popularity is its use for small-scale projects, making small teams and allows change requests at any stage of a project from the client. It works for client satisfaction. Instead of so much popularity and distinctive features, agile-scrum also has some limitations when used for large scale projects development that makes it less efficient for development. This article discusses the agile-scrum methodology and its limitations when using for large-scale project organization.

Penerapan Metode Rational Unified Process (RUP) Dalam Pengembangan Sistem Informasi Medical Check Up Pada Citra Medical Centre

The Rational Unified Process (RUP) method is an iterative and incremental software development method that focuses on architecture. The RUP method will be used in the development of a medical check-up information system on a Citra medical center because this method is proactively able to resolve the project risks associated with the client's evolving requirements requiring careful change request management. Less time is required for integration as the process of integration goes on throughout the software development life cycle and the development time required is less due to using of components over and over. RUP involves The client’s in The system development process, so the result will be accordance with client wishes. The system built is expected to make it easier for employees to manage patient data from anywhere and anytime.

Users' choice and change of allocated primary mental health professional in community-based mental health services: A scoping review.

The recovery model in mental health care emphasizes users' right to be involved in key decisions of their care, including choice of one's primary mental health professional (PMHP). The aim of this article was to provide a scoping review of the literature on the topic of users' choice, request of change and preferences for the PMHP in community mental health services. A search of the PubMed, Cochrane Library, Web of Science and PsycINFO for papers in English was performed. Additional relevant research articles were identified through the authors' personal bibliography. A total of 2,774 articles were screened and 38 papers were finally included. Four main aspects emerged: (1) the importance, for users, to be involved in the choice of their PMHP; (2) the importance, for users, of the continuity of care in the relationship with their PMHP; (3) factors of the user/PMHP dyad influencing users' preferences; and (4) the effect of choice on the treatment outcomes. While it is generally agreed that it is important to consider users' preferences in choosing or requesting to change their PMHP, little research on this topic is available. PMHPs' and other stakeholders' views should also be explored in order to discuss ethical and practical issues.

Detection of Syntax Similarity of Source Code using a Graph based Hybrid Technique

Software evolves inherently due to change requirement. The change request applied with intent to achieve the appropriate functionality of the software. This change inside the code makes some differences in previous code. Changes in somewhere in existing code may also affect some other part of the code. Our focus is on finding similarity of two codes to draw static call graph and program dependency graph which shows the dependencies and data flow among various part of the code then apply a distance metrics to find the percentage of similarity between two codes. This paper presents a dependency graph based hybrid technique (DGHT) for detection of similarity of two variations of python code. This method also includes a Machine learning technique which analyzes syntactic structure of object oriented software system. The objective is to apply the outcomes of this work on change impact analysis. The results of the framework will help to estimate actual impact set to optimize testing efforts.

Impact of Radiologist-Driven Change-Order Requests on Outpatient CT and MRI Examinations.

To assess impact of electronic medical record-embedded radiologist-driven change-order request on outpatient CT and MRI examinations. Outpatient CT and MRI requests where an order change was requested by the protocoling radiologist in our tertiary care center, from April 11, 2017, to January 3, 2018, were analyzed. Percentage and categorization of requested order change, provider acceptance of requested change, patient and provider demographics, estimated radiation exposure reduction, and cost were analyzed. P < .05 was used for statistical significance. In 79,310 outpatient studies in which radiologists determined protocol, change-order requests were higher for MRI (5.2%, 1,283 of 24,553) compared with CT (2.9%, 1,585 of 54,757; P < .001). Provider approval of requested change was equivalent for CT (82%, 1,299 of 1,585) and MRI (82%, 1,052 of 1,283). Change requests driven by improper contrast media utilization were most common and different between CT (76%, 992 of 1,299) and MRI (65%, 688 of 1,052; P < .001). Changing without and with intravenous contrast orders to with contrast only was most common for CT (39%, 505 of 1,299) and with and without intravenous contrast to without contrast only was most common for MRI (26%, 274 of 1,052; P < .001). Of approved changes in CT, 51% (661 of 1,299) resulted in lower radiation exposure. Approved changes frequently resulted in less costly examinations (CT 67% [799 of 1,198], MRI 48% [411 of 863]). Outpatient CT and MRI orders are deemed incorrect in 2.9% to 5% of cases. Radiologist-driven change-order request for CT and MRI are well accepted by ordering providers and decrease radiation exposure associated with imaging.

Bartolomeu: An SDN rebalancing system across multiple interdomain paths

Bartolomeu is a solution to enable stub networks to perform adaptive egress traffic load balancing across multiple interdomain routes by spreading the traffic across available paths according to a passive measurement of their performance. It defines a BGP-SDN architecture that increases the number of BGP routes that can be used by stub networks. Bartolomeu measures the available capacity of each path to any destination prefix, and allocates to each path a number of large flows that is proportional to its capacity. This strategy reduces the mean sojourn time, i.e., mean time to flow completion, compared to state-of-the-art traffic balancing techniques as ECMP. We develop a mathematical model to compute this time and compare with ECMP and single path (fast path) selection. An analysis of the traffic traces of two content providers was performed to ensure that our solution is deployable. An experiment with traffic exchange over the Internet is used to show that Bartolomeu can provide gains with real interfering traffic. A discrete-event simulator fed with the traces captured is used to asses Bartolomeu’s gains with prefixes with different number of flows, and flows with different sizes and arrival time. We observe in this experiment that Bartolomeu can reduce the sojourn time, compared to ECMP, by half when path rates differ in a factor of 3, or to a sixth when path rates differ in a factor of 10. We compute the maximum number of per-flow entries and the maximum entry change request rate to show that the resources required fit in with the specifications of the current generation of SDN switches.

A sample results show the frequency of various significant events, accumulated time corresponding to activities performance, number of actions being performed by different people, overall working time for employees, the degree of the human factor use, and the global cost connected with different activities. The following process models have been developed, simulated and optimized: Release of an employee, Locker room change request, Clothing size change request for an employee, Cabinet location change request, Clothing sets amount change request, Personal data change, Employment process, Registration of the own clothing for an employee, New cabinet order, New set of keys set up, Transfer of an employee, Clothing repair request.

Flexible Production Concept of a Low-Cost Battery Pack Housing for Electric Vehicles

Fixture and clamping technologies of automated production lines for structural components in vehicles turned out as the main cost driver with up to 29 % of total investment costs of the production equipment. Additionally, they limit the product flexibility for product variants and change requests during the product development process. Flexible production concepts, like jigless joining with component-integrated jig features (CJF) might be a promising approach to reduce component specific jig technology. Technical as well as economical aspects are investigated on a low-cost battery pack housing for electric vehicles and are compared to conventional concepts concerning annual production volumes.

A study on effectiveness of Building Information Modelling (BIM) on the Malaysian construction industry

The introduction of Building Information Modelling (BIM) in Malaysia has been fairly recent and is gaining popularity. Although most literature have been focused on the adoption and application of BIM in Malaysia construction industry, the effectiveness of BIM has not been investigated. This study aims to investigate the influence of BIM on the Malaysian construction industry. A qualitative approach was taken and interviews were conducted with professionals with prior knowledge in both the construction industry and BIM. Information obtained from the interviews was used to identify and categorise the determining factors. It was found that the application of BIM in Malaysian construction industry is somehow not fully effective in terms of time and cost, owing to the absence of standards in modelling and the frequent request for design changes. However, the results also show that BIM in Malaysia has the potential to be as effective as other developed countries if the major problems addressed being solved.

Influence of the Religious Factor on Political Identity in the Lower Volga Region

The article is aimed at finding a&nbsp;correlation between an individual’s religion and his political guidelines, which form a&nbsp;political identity. The article analyzes data of the sociological survey conducted in the spring of 2020 in the Lower Volga Region by the research team of the Department of History, Political Science and Sociology of the Saratov State Law Academy. The sample size was 1,100 persons. The collection of primary sociological information was carried out by means of the Internet survey of respondents using the Google forms service. Representatives of the Astrakhan Oblast (184 respondents), Volgograd Oblast (307) and Saratov Oblast (609) were interviewed. The theoretical significance of the study lies in the substantiation of the importance of religious affiliation in shaping political orientations and in mainstreaming the religious component of the political identity of citizens. The study covers a&nbsp;range of topics related to the politicization of religion and the sacralization of politics. The application of the study is to determine the importance of religiosity in contemporary political processes. This leads to a&nbsp;conclusion on the intersection/overlap of two identities: religious and political that is essential for the formation of a&nbsp;common civic identity in modern post-secular Russia. The boundaries of religious and political identities have not been strictly matched. A&nbsp;request for fairness and change has been identified and there was discontent over the basic functioning of the political system, which creates risks of radicalization of the public mood. According to the results of the study, these public sentiments indicate that symbolic identification prevails. Political secularization in the public consciousness of the population of the Lower Volga region has not occurred. At the same time, the religious factor as part of the citizens' world view has a&nbsp;certain influence on the formation of political identity in the region.
