Historic City

This article reports on the technical development and testing of the basic components of a virtual environment platform that could be used for the cross-disciplinary study of complex urban realities, such as the historic city of Nicosia, Cyprus - the last divided capital of Europe. This platform captures data of virtual visitors' movements in space, and the article suggests that these data could help better understand the impact of planning scenarios and design interventions in open public spaces that used to be popular among the citizens of the historic city. The article presents how this platform uses interaction and immersion opportunities to engage citizens and stakeholders in the management of public open spaces that are associated with built heritage. Crowd simulation is discussed as a computational technique that when is combined with the presented virtual environment platform, and under the right conditions, would contribute to a digital practice for small-scale urban modelling. However, it is beyond the scope of this technical note to provide a full empirical testing and validation of the presented immersive virtual environment.

AbstractLarge and small scale construction projects have waste that cannot be predicted in advance, even the amount cannot be predicted directly, whether it is in large or small amounts. The existence of waste can have a significant impact that can affect construction costs. Waste can have both negative and positive impacts. Good waste management will have a positive impact on the company in terms of cost, even time, and quality, but if the waste that occurs cannot be handled or managed properly it will harm the company in terms of cost, time, and even in terms of quality. In this case, the party that always gets the impact of the waste is the contractor.This study focuses on mitigating the occurrence of waste that is how to minimize it. Thisstudy uses the distribution of questionnaires to the contractor in Surabaya. The results of this study are 5 item indicators on how to minimize the highest ranking. The 5 items are Updating material requirements, Mixing, transporting, and placing concrete at the right time, Increasing the competence and expertise of labor, Provision of good and adequate material/warehouse storage facilities, and accurate material measurement.  Abstrak Proyek konstruksi dalam skala besar maupun kecil, memiliki waste yang tidak dapat diprediksi sebelumnya, bahkan jumlahnya pun tidak dapat diprediksi secara langsung, apakah itu dalam jumlah besar ataupun jumlah yang kecil. Adanya waste dapat memberikan dampak yang signifikan yang dapat mempengaruhi biaya konstruksi. Pada dasarnya waste dapat memberikan dampak negatif maupun positif. Pengelolaan waste yang baik akan memberikan dampak positif bagi perusahaan dalam segi biaya, bahkan waktu dan mutu, namun apabila waste yang terjadi tidak dapat diatasi atau dikelola dengan baik maka akan memberikan dampak negatif bagi perusahaan dalam segi biaya, waktu bahkan dalam hal mutu. Dalam hal ini pihak yang selalu mendapatkan dampak dari adanya waste adalah pihak kontraktorPenelitian ini memfokuskan pada faktor penanggulangan terjadinya waste yaitu cara meminimalisirnya. Penelitian ini menggunakan penyebaran kuisioner kepada pihak kontraktor di Surabaya. Hasil dari penelitian ini adalah 5 item indicator cara meminimalisir yang memiliki ranking tertinggi. 5 item tersebut adalah Updating kebutuhan material, Mencampur, mengangkut dan menempatkan beton pada waktu yang tepat, Meningkatkan kompetensi dan keahlian tenaga kerja, Penyediaan fasilitas penyimpanan material/gudang yang baik dan memadai, dan Pengukuran bahan yang akurat.

The Relationship

This is the second and final publication analyzing presence, immersive tendencies of individuals, and design comprehension. The effectiveness measurement problem is described in this article by means of a methodology to find the best design review process subject to certain criteria. The effectiveness measurement problem originates from our inability to logically understand the impact of a process or media differences on design comprehension; and it reconciles such differences in strengths of media that cannot be effectively covered by the relationship problem described in the first technical note. We illustrate the methodology with design review experiments where Computer Aided Virtual Environment (CAVE™2) is investigated as a possible virtual environment for product design reviews. Based on the measurable usability attributes of the design review process, the CAVE was considered to be a good solution achieving maximum utility. However, costs may hinder the ability to use CAVE as a tool.

The European Union has regulated by law the elimination of barriers to guarantee the right to free movement, freedom of choice and non-discrimination of people with reduced mobility (PRM). This regulation also affects air transport. More specifically, airports of the member states must offer a quality assistance service to PRM, with the adequate human and technical resources to guarantee their rights. The changing characteristics of the operation of an airport (delays, cancellations, breakdowns, etc.) add great complexity to the design and management of a PRM service. Internet of Things (IoT) technologies pose a unique opportunity to integrate new services and solutions to deal with these problems. This work focuses on the use of modeling and simulation techniques for the evaluation of the impact of the incorporation of new IoT-based elements (such as autonomous vehicles, smart devices and 5G-enabled systems), for the improvement of the PRM service.

Cloud Computing offers the possibility of computing resources, allowing remote access to software, storage and data processing through the Internet. Infrastructures as a Service (IaaS), it is a flexible space which can be used as an experimental environment, in which experiments can be carried out similar to a real environment, such as in a cluster can be carried out. Before making installations and changes in a production cluster or select resource in the cloud, it is important to analyze the impact of this change. For this reason we propose using the cloud to carry out the study of previous viability. In this paper, we observe the viability of using the cloud to analyze the behavior of the Checkpoint as one of the Fault Tolerance strategies, establishing the differences that exist in the information generated in a real environment (cluster) and a virtual environment (cloud). The results obtained show that due to the variability of the cloud, the impact on the benefits cannot be analyzed. However, the cloud is suitable for extracting the spatial and temporal behavior pattern of the checkpoint, which helps to characterize it and this will help us to know the right configuration and the development of methodologies and tools that simulate and predict the execution of the checkpoint in a real environment.

Abstract. In the study, the neural basis of emotional reactivity was investigated. Reactivity was operationalized as the impact of emotional pictures on the self-reported ongoing affective state. It was used to divide the subjects into high- and low-responders groups. Independent sources of brain activity were identified, localized with the DIPFIT method, and clustered across subjects to analyse the visual evoked potentials to affective pictures. Four of the identified clusters revealed effects of reactivity. The earliest two started about 120 ms from the stimulus onset and were located in the occipital lobe and the right temporoparietal junction. Another two with a latency of 200 ms were found in the orbitofrontal and the right dorsolateral cortices. Additionally, differences in pre-stimulus alpha level over the visual cortex were observed between the groups. The attentional modulation of perceptual processes is proposed as an early source of emotional reactivity, which forms an automatic mechanism of affective control. The role of top-down processes in affective appraisal and, finally, the experience of ongoing emotional states is also discussed.

This study attempted to identify the impact of internal work environment on the retention of healthcare providers at Turaif General Hospital in the Kingdom of Saudi Arabia. In particular, the study aimed to identify the dimensions of work circumstances, compensation, and relationship with colleagues, professional growth, and the level of healthcare providers’ retention. In order to achieve the study goals, the researcher used the descriptive analytical approach. The researcher used the questionnaire as the study tool. The study population comprised all the healthcare providers at Turaif General Hospital. Questionnaires were distributed to the entire study sample that consisted of 220 individuals. The number of questionnaires valid for study was 183 questionnaires. The research findings were as follows: the participants’ estimate of the work circumstances dimension was high (3.64), the participants’ estimate of the compensation dimension was moderate (3.32), the participants’ estimate of the relationship with colleagues dimension was high (3.62), the participants’ estimate of the professional growth dimension was weak (2.39), and the participants’ estimate of healthcare providers’ retention level was intermediate (2.75). Accordingly, the researcher’s major recommendations are: the need to create the right atmosphere for personnel in hospitals, the interest of the hospital to provide the appropriate conditions for the staff in terms of the physical and moral aspects for building the work adjustment in the staff, and conducting training courses and educational lectures for personnel in hospitals on how to cope with the work pressures.

The purpose of the present study is twofold: first, to investigate the true values of Muslim owner managers; second, to examine the impact of these values on entrepreneurial orientations of Muslim small-scale entrepreneurs. 850 Muslim owner managers were selected randomly using the sampling frame provided by MajlisAmanah Rakyat Malaysia (MARA). 162 completed questionnaires were collected and analyzed. For this paper only two dimensions of entrepreneurial orientations were analyzed: proactive orientation and innovative orientation. Interestingly, the findings revealed that Muslim businessmen/women are honest, loyal, disciplined and hard working. Loyalty and honesty are positively related to proactive orientation, while discipline and hard-work are positively related to innovative orientation. The findings provide implications for existing relevant theories, policy makers, practitioners and learning institutions.

The right to adequate housing is a constitutional imperative which is contained in section 26 of the Constitution. The state is tasked with the progressive realisation of this right. The allocation of housing has been plagued with challenges which impact negatively on the allocation process. This note analyses Ekurhuleni Metropolitan Municipality v Various Occupiers, Eden Park Extension 51 which dealt with a situation where one of the main reasons provided by the Supreme Court of Appeal for refusing the eviction order was because the appellants subjected the unlawful occupiers to defective waiting lists and failed to engage with the community regarding the compilation of the lists and the criteria used to identify beneficiaries. This case brings to the fore the importance of a coherent (reasonable) waiting list in eviction proceedings. This note further analyses the impact of the waiting list system in eviction proceedings and makes recommendations regarding what would constitute a coherent (reasonable) waiting list for the purpose of section 26(2) of the Constitution.

The concept of tolerance is gaining its importance in the midst of an international society suffering from violence, wars and internal and international crises. It is practiced by extremist and extremist forces and movements acting in the name of religion to exclude the different Muslim and non-Muslim people according to the unethical practices and methodologies of Islamic law and reality. , Cultural, civilization .. that distinguish our world today. The society today is suffering from the ideas of the intellectual and aesthetic views of the different ideologically, ethnically, culturally and religiously in the world of the South. This is what the end-of-history thesis of Fukuyama and the clash of civilizations represented to Huntington. Therefore, it is necessary to confront these extremist and extremist ideas and behaviors. Peace, security and freedom in the international community of justice and equality, needs to be addressed intellectual, cultural, moral and political before they are legal, these treatments are based on dialogue and cooperation and trust and respect and mutual recognition and tolerance so we find the importance of tolerance to The international community is concerned about the need for mechanisms that confront terrorism and violence with an ideology based on respect for the right of diversity, diversity and pluralism. Accordingly, tolerance is a political, cultural and moral necessity based on international legal foundations represented by the United Nations. Through its conferences, declarations and international resolutions issued by it and its specialized agencies, culminating in the Universal Declaration of Tolerance and the International Day of International Peace, and the political foundations represented by democracy and global citizenship that respects all identities and seeks to respect the rights of other identities under the umbrella of international identity Nsanhuahdh respects everyone, a society with a humanitarian goal of a global civil and Ahdlaaaraf borders and the identity of certain Qomahdolh, cultural and educational foundations through plans and programs with educational encourage a spirit of tolerance and world peace. The study was divided into three topics: the first dealt with the concept of tolerance and world peace, and the second topic dealt with the impact of international law and citizenship. In the promotion of world peace "as one of the elements of global tolerance. The last topic included" the role of democracy and education education "in the promotion of world peace and concluded the study by conclusion.
