Global Navigation Satellite Systems are expected to meet system-defined integrity requirements when users utilize the system for safety critical applications. While the guaranteed integrity performance of GPS and Galileo is publicly available, their integrity assurance procedure and related methodology have not been released to the public in an official document format. This paper summarizes the integrity assurance procedures of Global Positioning System (GPS) and Galileo, which were utilized during their system development, through a literature survey of their integrity assurance methodology. GPS Block II assures system integrity using the following methods: continuous performance monitoring and maintenance on Space Segment (SS) and Control Segment (CS), through a cause and effect analysis of anomalies and a failure analysis. In GPS Block III, to achieve more stringent integrity performance, safety requirements are integrated into the system design and development from its starting phase to the final phase. Galileo's integrity performance is provided in the Integrity Support Message (ISM) format, as Galileo utilizes a Dual Frequency Multi Constellation (DFMC) Satellite Based Augmentation System (SBAS) and Advanced Receiver Autonomous Integrity Monitoring (ARAIM) to serve safety critical applications. The integrity performance of Galileo is ensured by using a methodology similar to GPS Block II (i.e. continuous performance monitoring and maintenance on the system). The integrity assurance procedures reviewed in this paper can be utilized for a new satellite navigation system that will be developed in the near future.

Integrity plays a fundamental role in the feasibility of 'liability critical' applications. Road charging, e.g. road tolling in urban zones or on highways, represents a series of liability critical applications where a guarantee in integrity could be a true enabler: being the mechanism that prevents the incorrect charging of users and enabling the advancement of these applications using GNSS such as Galileo and EGNOS that provide integrity mechanisms. However, the integrity of the end user position is not guaranteed by the EGNOS and Galileo integrity services alone as provided. Algorithms have been developed to supply a guarantee on the performance attainable at the user level through the provision of a horizontal protection level that responds to local user conditions such as multipath or interference. In addition, an application has been developed that implements road charging mechanisms based on the availability of user-level integrity. Results obtained show that the user-level integrity algorithms provided the required level of integrity guarantee and granularity of the horizontal protection levels necessary for executing urban and rural (highway) road charging. In addition, the road charging application developed shows that the current application domain requirements can be met through the provision of guaranteed integrity and that further reductions in the horizontal protection levels along with increased signal availability will enable future road charging modalities.

Effects of food scandals on religious belief, human health and even on causes of death indicate that firms and consumers are vulnerable to integrity risks in the global supply chain. Mitigating the integrity risk and maintaining the credence quality products like halal food is very challenging, if not impossible. Our aim in this research is to show that supply chain integration can mitigate the halal food integrity risk. To illustrate this idea, we have conducted case studies and interviews in seven Malaysian chicken supply chain focal firms. We unpack the halal integrity risks along the supply chain, such as production risk, raw material risk, food security risk, outsourcing practices risk, service risk, and logistics risk. The research argues that supply chain integration, such as internal integration and external integration practices, could minimize the halal integrity risk. The advantages of supply chain integration in mitigating the halal integrity risk are also highlighted in this paper.

In 2012, Psy's music video 'Gangnam Style' spread through parodies, and gained explosive popularity. In 2016, there was a case so-called as 'baseball ground cheering song' in which a author(songwriters) claimed an infringement of the 'right of integrity' related to cheering songs used by professional baseball teams. In response, the court denied violating the right of integrity in 2019. These cases have different effects depending on whether or not the 'right of integrity' is claimed. This study attempted an economic analysis in addition to a legal analysis of the right of integrity. Korean copyright law regards even simple changes that go against the author's will as a infringement of the 'right of integrity' even if they do not harm honor or reputation. Such legislation is one of the most strongly protected forms in the world, so it cause many problems. Meanwhile, we analyzed the cost-benefit analysis of Psy's 'Gangnam Style' case and the 'baseball ground cheering song' case. As a result of the analysis, the right to integrity is inefficient in quantitative and qualitative aspects. Therefore, the right of integrity should be reconsidered with the focus on 'popular music'. In particular, considering the development of information communication technology and changes, a revision direction is needed to meet the purpose of the copyright act. Furthermore, in order to solve the legal issues under the Copyright Act, the requirement for infringement of the right of integrity should be relaxed. Then, we proposed the establishment of a proviso clause on the right of integrity.

Purpose: This research aims to investigate the impact of corporate integrity on stock price crash risk. Research design, data, and methodology: Taking 1419 firms listed in Shenzhen Stock Exchange in China as a sample, this paper empirically analyzed the relationship between corporate integrity and stock price crash risk. The main integrity data was hand-collected from Shenzhen Stock Exchange Website. Other financial data was collected from CSMAR Database. Results: Findings show that corporate integrity can significantly decrease stock price crash risk. After changing the selection of samples, model estimation methods and the proxy variable of stock price crash risk, the conclusion is still valid. Further research shows that the relationship between corporate integrity and stock price crash risk is only found in firms with weak internal control and firms in poor legal system areas. Conclusions: Results of the study suggest that corporate integrity has a significant influence on behaviors of managers. Business ethics reduces the likelihood of managers to overstate financial performance and hide bad news, which leads to the low likelihood of future stock price crashes. Meanwhile, corporate integrity can supplement internal control and legal system in decreasing stock price crash risks.

The study aims to explore the empirical effect of social intelligence, integrity, self-efficacy, and affective commitment on job satisfaction, and also to prove the theoretical model regarding affective commitment as a mediator between social intelligence, integrity, self-efficacy, and job satisfaction. This research uses a quantitative approach to the survey method through a Likert scale model questionnaire. The questionnaire for all research variables is reliable with an alpha coefficient > 0.7. The research participants are comprised of 386 teachers in Indonesia selected by accidental sampling. Data analysis uses path analysis supported by descriptive statistics and correlational matrices. The research results indicate that social intelligence, integrity, self-efficacy, and affective commitment have a significant effect on job satisfaction. Besides, affective commitment also indirectly mediates the effect of social intelligence, integrity, and self-efficacy on job satisfaction. Thus, a new model regarding the effect of social intelligence, integrity, and self-efficacy on job satisfaction mediating by affective commitment was confirmed. The research suggested that the teachers' job satisfaction can improve through social intelligence, integrity, self-efficacy, and affective commitment. Therefore, researchers and practitioners can adopt a new empirical model to enhance job satisfaction through social intelligence, integrity, self-efficacy, and affective commitment in the future.
