Objectives: Through the reflection on the city’s response to the crisis in the process of tobacco control, a comprehensive and systematic public safety prevention and control system will be built to help cities cope with future risks and challenges. Methods: By using the methodological principle of the unity of subject and object and systematic research, this paper analyzes the problems from the three aspects of subject, object and means, and puts forward three important links of prevention, response and guarantee to construct a large urban public security system, and these three links support each other form a closed loop of risk prevention and control urban public security. Results: Under the background of tobacco control, it is feasible to a reliable whole-cycle management system for urban emergency response and accident rescue, a sound basic public safety guarantee system and a whole-society participation system. Conclusions: Due to the change of global climate conditions and the increase of flow people in the social environment, human beings will face a more complex living environment in the future and may encounter more extreme problems. It can be said that at present and even in the future, global urban public security risk management work is facing a grim situation. WHO research shows that smoking will increase the risk of new crown virus infection among smokers and their surrounding population.China is a big smoking country and in the stage of rapid urbanization. Many citiesare densely populated. Once there is an epidemic infection, the cities will face a severe public security situation. Smoking will not only have an adverse impact on personal health, but also the fires in factories, homes and forests caused by smoking.Since the Chinese government’s tobacco control in 2014, various accidents caused by smoking have caused great adverse effects.Smoking in public places has great hidden dangers of public safety, which leads us to think about the risk management of urban public safety.In the context of tobacco control, we should use scientific thinking and methods to construct a new pattern of urban public security risk management. Another important concept is to implement the risk management concept and the value of prevention first in the management of public affairs, so as to create a situation of risk sharing and coordinated response of the whole society.

This paper measured the mood of College of Science, Engineering and Technology (CSET) academics following the merger between University of South Africa (UNISA), Vista University Distance Education Campus (VUDEC) and Technikon SA (TSA). The formulated statements, potential human resources related risks with association to the statements were articulated. The results obtained from the survey indicated that had the risk assessment been undertaken in CSET, the risk of losing/ retaining critical skills, corporate memory, and the inability to attract these critical skills to CSET could have been higher on the risk dashboard following the post-merger of UNISA, VUDEC and TSA.

Risk management is a set of procedures and methodologies that used to identify, measure, monitor, and control risks that could be aroused from the business of banks. This article aims to analyze the implementation of risk management system at Baitul Qiradh Bina Insan Mandiri and its impact on musharaka financing. The sample for this research is Micro Small Business Group at Kuta Alam’s regency which was financed by the Baitul Qiradh. Data for this research was gathered through interviews, observation, and documentation study. The findings suggest that there were three risk possibilities that could escalate at the financing project, namely business risk, shrinking risk, and character risk. Among these risks, the Baitul Qiradh experiences two of them, which were business and character risks. Therefore, the efforts were made to minimize the risk of Baitul Qiradh Bina Insan Mandiri by applying the 5C concept, namely character, capability, capital, condition, and collateral). ========================================================================================================Manajemen risiko adalah serangkaian prosedur dan metodologi yang digunakan untuk mengidentifikasi, mengukur, memantau, dan mengendalikan risiko yang timbul dari kegiatan usaha bank. Tujuan penelitian adalah untuk menganalisis sistem manajemen risiko yang diimplementasikan pada Baitul Qiradh Bina Insan Mandiri dan dampaknya terhadap kelancaran pembayaran dalam pembiayaan musyarakah. Pembahasan kajian hanya terfokus ke manajemen risiko pembiayaan musyarakah pada kelompok usaha dalam Rumpun Kuta Alam yang dibina oleh Baitul Qiradh Bina Insan Mandiri Banda Aceh. Pengumpulan data dilakukan dengan wawancara, observasi, dan studi dokumentasi. Hasil penelitian menunjukkan bahwa dalam melakukan pembiayaan tersebut Baitul Qiradh Bina Insan Mandiri tidak terlepas dari kemungkinan terjadinya 3 aspek risiko, yaitu: risiko bisnis yang dibiayai (busness risk), risiko berkurangnya nilai pembiayaan (shrinking risk), dan risiko karakter buruk mudharib (character risk). Dari ketiga aspek risiko tersebut, risiko pembiayaan musyarakah yang muncul dalam tiga kelompok usaha pada Rumpun Kuta Alam adalah risiko bisnis yang dibiayai (business risk) dan risiko karakter buruk mudharib (character risk). Upaya yang dilakukan untuk meminimalisir risiko tersebut, Baitul Qiradh Bina Insan Mandiri menerapkan secara ketat konsep 5C yaitu karakter (character), kapasitas atau kemampuan (capacity), modal (capital), kondisi (condition) dan jaminan (collateral).

<p><em>This study aims to determine the effect of the antecedents of Supply chain quality risk management (SCQRM) implementation on organizational performance with the moderating role of organizational culture in the Indonesian Navy. Based on data from questionnaire survey data totaling 260 Indonesian Navy officers, the SCQRM theory model is proposed and the structural equation model is used to test the proposed hypothesis. The results show that strategic leadership, information, and control mechanisms are significant antecedents of SCQRM implementation. Furthermore, strategic leadership and information significantly contribute to organizational performance. An interesting finding is that control mechanisms do not have a direct impact on organizational performance, but they do contribute indirectly to organizational performance mediated by SCQRM implementation. Also, SCQRM implementation significantly contributes to organizational performance and the moderating effect of organizational culture strengthens the relationship between SCQRM implementation and organizational performance. This study focuses on the concept and implementation of SCQRM in Indonesian Navy logistics with the role of strategic leadership, information, control mechanisms, and organizational culture to improve organizational performance using single respondents and expert perceptions, namely Indonesian Navy Officers. The managerial implications suggest that complementary benefits arise from the adoption of a more holistic approach to the management of supply chain quality risk at the organizational level with</em><em> </em><em>supported the role of strategic leadership, information, control mechanisms, and organizational culture will improve organizational performance. Three contributions to science in the development of SCQRM theory. <strong>First</strong>, this study develops an SCQRM theoretical model with three unique dimensions (supplier development, risk management integration, and proactive product recall). <strong>Second</strong>, this study provides a new perfection of how the complementarity system of SCQRM is operated to improve organizational performance. Moreover, the findings imply that a successful SCQRM implementation is built on a complementarity power in risk management resources and routines. The multiple manifestations of the three SCQRM dimensions are all driven by a cohesive, yet unobserved synergy, which also forms one of the competencies of the organization. <strong>Third</strong>, this study also provides a new perfection on the role of strategic leadership, information and control mechanisms as antecedents of SCQRM implementation, and the moderating role of organizational culture that strengthens the relationship between SCQRM implementation and organizational performance</em><em>.   </em><strong></strong></p>

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper OTC 30437, “Risk Management and Control for CO2 Waterless Fracturing,” by Siwei Meng, Qinghai Yang, SPE, and Yongwei Duan, PetroChina, et al., prepared for the 2020 Offshore Technology Conference Asia, originally scheduled to be held in Kuala Lumpur, 2–6 November. The paper has not been peer reviewed. Copyright 2020 Offshore Technology Conference. Reproduced by permission. Given shortages and uneven distribution of water resources in China, efforts must be made to develop waterless fracturing techniques. The fluid experiences high pressures and low temperatures during carbon dioxide (CO2) waterless fracturing operations, which can lead to accidents and environmental pollution. In the complete paper, a safety-management approach and a contingency plan for such operations are developed. At the time of writing, this CO2 waterless fracturing methodology has been completed successfully more than 20 times. Surface Process Work Flow of CO2 Waterless Fracturing The basic process of a CO2 waterless fracturing operation is shown in Fig. 1. First, several CO2 storage tanks are connected in parallel. The booster, sealed blender, fracturing pump (all mounted on trunks), and wellhead equipment are connected. The measuring trunk communicates with each vehicle to monitor operation status. Proppant is put into the sealed blender, into which liquid CO2 is injected for pre-cooling. Pump testing is conducted on the high-pressure line and the wellhead and the low-pressure liquid supply line is pressure-tested. Operation does not proceed until pressure-testing results are positive. Afterward, liquid CO2 is injected into formations to fracture them and, moreover, extend created fractures. The sealed blender is enabled to inject prop-pants, and displacement begins after the end of proppant injection. Finally, a series of tasks, including well shut-in for soaking and flowback, is carried out successively.
