Note for the P versus NP Problem

P versus NP is considered as one of the most fundamental open problems in computer science. This consists in knowing the answer of the following question: Is P equal to NP? It was essentially mentioned in 1955 from a letter written by John Nash to the United States National Security Agency. However, a precise statement of the P versus NP problem was introduced independently by Stephen Cook and Leonid Levin. Since that date, all efforts to find a proof for this problem have failed. Another major complexity class is NP-complete. It is well-known that P is equal to NP under the assumption of the existence of a polynomial time algorithm for some NP-complete. We show that the Monotone Weighted Xor 2-satisfiability problem (MWX2SAT) is NP-complete and P at the same time. Certainly, we make a polynomial time reduction from every directed graph and positive integer k in the K-CLOSURE problem to an instance of MWX2SAT. In this way, we show that MWX2SAT is also an NP-complete problem. Moreover, we create and implement a polynomial time algorithm which decides the instances of MWX2SAT. Consequently, we prove that P = NP.

Australian Anti-encryption Legislation and Its Impacts on Security and Privacy

Telecommunications and Other Legislation Amendment (Assistance and Access) Act 2018 gives relevant authorities (e.g. law enforcement, national security agencies and intelligence agencies) significant new powers regarding access to encrypted communications data, and hence extensive public attention have been attracted and opinions expressed concerning general security and privacy of users. This essay will first briefly introduce the key contents of the Assistance and Access Act 2018, then discuss how it will affect security and privacy of users respectively by considering both supporting and opposing arguments, and then further the discussion into a global environment by examining the history of a variety of efforts on similar powers. It concludes that though the Assistance and Access Act 2018 has sophisticated oversight mechanism and takes into consideration the most concerned systemic weaknesses security issue, its definition and guidance are vague and is likely not practical to achieve what the Act is designed for in practice. The potential overreach of the Act not only will impose great threats to system security as a whole, but also will breach the principle of privacy.

Evolving research on groundwater governance and collective action for water security: A Global bibliometric analysis

Groundwater is a significant source of freshwater supply globally. State-mandated groundwater regulatory frameworks are often pervasive and have failed to reap tangible outcomes. The participatory approach of groundwater governance has surfaced to understand human-groundwater relations through collective action going beyond the techno-managerial paradigm. Hence, the study is carried out to provide a comprehensive and systematic review of the evolution and trends of research in groundwater governance and collective action deploying bibliometric analysis to understand the political economy of groundwater. A total of 356 scholarly peer-reviewed and grey literature published from 2000 to 2022 was compiled. A substantial increase in publications after 2013 was observed. USA and India lead in publication contributions in terms of geographical distribution. Three peer-reviewed journals were prominent publishing outlets: Hydrogeology, Water, and Water Alternatives. The analysis of 814 keywords co-occurrence shows that "groundwater," "governance," and "collective action" were the most extensively used keywords. The emerging themes observed are governance and institutions, cooperative management, and policy. Our findings signify that cooperative management or collective action will be prioritised to understand human-groundwater relations by making the invisible resource visible integrating socio-cultural perspectives.

Prognostic value of plasma diquat concentration in patients with acute oral diquat poisoning: a retrospective study.

Diquat poisoning is an important public health and social security agency. This study aimed to develop a prognostic model and evaluate the prognostic value of plasma diquat concentration in patients with acute oral diquat poisoning, focusing on how its impact changes over time after poisoning. This was a retrospective cohort study using electronic healthcare reports from the Second Hospital of Hebei Medical University. The study sample included 80 patients with acute oral Diquat poisoning who were admitted to the hospital between January 2019 and May 2022. Time-to-event analyses were performed to assess the risk of all-cause mortality (30 days and 90 days), controlling for demographics, comorbidities, vital signs, and other laboratory measurements. The prognostic value of plasma DQ concentration on admission was assessed by computing the area under a time-dependent receiver operating characteristic curve (ROC). Among the 80 patients, 29 (36.25%) patients died, and 51 (63.75%) patients survived in the hospital. Non-survivors had a median survival time (IQR) of 1.3(1.0) days and the longest survival time of 4.5 days after DQ poisoning. Compared with non-survivors, survivors had significantly lower amounts of ingestion, plasma DQ concentration on admission, lungs injury within 24 h after admission, liver injury within 24 h after admission, kidney injury within 24 h after admission, and CNS injury within 36 h after admission, higher APACHE II score and PSS within 24 h after admission (all p < 0.05). Plasma Diquat concentration at admission (HR = Exp (0.032-0.059 × ln (t))) and PSS within 24 h after admission (HR: 4.470, 95%CI: 1.604 ~ 12.452, p = 0.004) were independent prognostic factors in the time-dependent Cox regression model. Plasma DQ concentration at admission and PSS within 24 h after admission are independent prognostic factors for the in-hospital case fatality rate in patients with acute oral DQ poisoning. The prognostic value of plasma DQ concentration decreased with time.

Securing Cloud Computing Services with an Intelligent Preventive Approach

Cloud computing is a technological marvel that transcends conventional boundaries by utilizing an Internet-based network of remote servers to store, manage, and process data and many other services. It represents a contemporary paradigm for delivering information technology services. Today, cloud computing services have become indispensable for both individuals and corporations. However, adopting cloud services presents fresh challenges in terms of service quality, resource optimization, data integration, cost governance, and operational security. The security of cloud services is of supreme importance, given the open and distributed nature of the environment, making it susceptible to various cyberattacks, such as Denial of Service (DoS) or Distributed DoS (DDoS) attacks, among others. Cyberattacks can have severe repercussions on the availability of cloud services, potentially causing complete DoS. In numerous instances, the detection of attacks is delayed, pushing cloud platforms to a breaking point. Emphasizing the importance of proactive measures, it becomes crucial to identify and alert about any suspicious access long before the latter reaches a critical stage, mitigating the risks and preventing potential service disruptions. This study introduces a preventive approach that utilizes artificial intelligence techniques to improve the security of cloud services. The proposed method aims to detect and flag potential attack behaviors well in advance before they affect service quality. To achieve this, the particular method involves periodic identification and measurement of critical information on service access and resource utilization. This can be accomplished by analyzing cloud server logs or integrating dedicated sniffing software to capture and store technical traffic details. Subsequently, the collected data are processed by analyzing traffic properties to proactively identify and report any indications of cyberattacks.

Digitalisation and its Impact on Social Protection Programmes Effectiveness: A Case from South Africa

The benefit of digitalisation, including the use of information management systems and electronic databases, in improving the effectiveness of social protection programmes is acknowledged by researchers and practitioners. However, concerns about digital- and financial exclusion stemming from increased reliance on digital technologies have also surfaced in recent studies. This study uses official data from South Africa's General Household Survey and the Global Findex database to explore these concerns. The potential gains of expanding social protection programmes through digitalisation are tested with simulations and distinct levels of income shocks. Additionally, two logistic regressions are employed to analyse relevant demographic variables for digital and financial inclusion. In combination with the quantitative approach, qualitative interviews were conducted with social protection experts from the South African Social Security Agency to gain insights into the impact of the digitalisation of social protection programmes. The results suggest that digitalising identification and delivery mechanisms in social protection improves equality through increased income levels. Digital access is associated with education, income, gender, population group, family size, and participation in the formal or informal sector. Financial access is linked to education level and gender. The study also identified perceived opportunities, including enhanced verification and streamlined application processes, which can improve programme effectiveness. However, integration, coordination, limited digital infrastructure, and digital illiteracy challenges may increase both digital- and financial exclusion.

Security governance, harms and resistance: Recalibrating security and redefining incivility through legitimacy concerns

Security governance, harms and resistance: Recalibrating security and redefining incivility through legitimacy concerns

ECONOMIC STABILITY IN THE LIGHT OF FINANCIAL CRIME

Economic crime creates an environment of instability and insecurity, leading to a loss of confidence in the economic system. When individuals and companies perceive widespread corruption and fraud, it inevitably leads to a decline in economic activity, resulting in economic insecurity in the country. This study aims to analyze the trends of criminal policy in combating economic crime, shedding light on some economic growth indicators in Algeria, and then identifying the effectiveness of criminal policy in achieving economic security. The study concluded by emphasizing that economic security can only be achieved through the adoption of punitive and preventive policies, increasing the vigilance and caution of security agencies, and reducing the escalation of economic crimes. Updating the legislative system and activating legal texts more strongly are necessary steps.

Therefore, three Baltic states have made an agreement on building more stable electricity transmission system within Baltic region and to connect with European transmission systems, building new stations with synchronous compensators and energy storage systems. In order to build a system, that allows to include more energy from renewable resources and secure possible disbalances in system, Latvian TSO operator is building a new battery energy storage system. This paper is aimed to look at what are the costs of this battery energy storage system from climate perspective to Latvia and its society in order to gain energy security and possibility to include more energy from renewable resources.

Air India pee gate case – need for comprehensive SOPs in customer management

Learning outcomes This case study allows students to appreciate the value of standard operating procedures in customer management. This case study emphasises the role of employees in delivering superior customer experience. This case study explores many facets of customer experience, reputation, social class membership and standard operating procedures (SOPs). Students will be able to apply theories of customer experience, behavioural psychology and service dimensions relevant to the airline industry. After completing this case study, students will be able to do the following:1. Evaluate the value of SOPs in Customer ManagementThis case study refers to the need for adhering to SOPs to deal with complex situations. Students will be able to evaluate whether compliance to SOPs could have helped Air India avoid the crisis or was it possible that a culture of absolute commitment to customer wellbeing could have prevented the crisis.2. Apply the theory of defensive attribution in customer grievance handling. Discuss if reducing customer effort in getting their problem solved can result in superior customer service.The victim had attributed the blame for not insisting on filing a complaint to the crew. Air India crew had defended their actions or lack of it by stating that they had followed the rule book. Students will be able to appreciate the need for a swift redressal mechanism to protect the self-image and self-esteem of the person/group involved. They will also understand that customer service interactions designed to solve customer problems swiftly and easily can be a very simple dictum to guide all employees in their decision-making while handling a customer complaint. 3. Evaluate the relationship between customer satisfaction and customer experience and examine the value of net promoter score (NPS) to study customer satisfaction. Air India Airlines was catering to varied customer groups such as the Indian diaspora, large student population pursuing education abroad, first-time flyers and the rising middle class with travel aspirations. Customer expectations vary across segments and change over their lifetime. Airline staff must trace customer corridors and deliver on customer expectation across the touch points that matter to them to ensure meaningful and relevant service delivery. Students will have an opportunity to evaluate the NPS in measuring customer satisfaction and debate whether it is a sufficient metric to guide the organisation on delivering and monitoring customer experience. 4. Examine why reputation risk management and not crisis management should be the focus of Air India in delivering superior customer service because nearly 70%–80% of market value for a company comes from its intangible assets such as brand equity and reputation. Students will discuss crisis management i.e. handling the threat to reputation after it has occurred and reputation risk management i.e. proactively managing potential threats to its reputation by taking timely actions to avoid or mitigate it. There are three factors (reputation reality gap, changing beliefs and expectation and weak internal coordination) that determine reputational risks. Students can evaluate this model to determine if Air India should address these three factors to manage its reputation proactively. Case overview/synopsis This case study is set around an incident that happened on 26 November 2022, on Air India flight bound for Delhi from New York when an inebriated 34-year-old man had peed on a 72-year-old woman. The perpetrator of the crime had walked free, and the victim was left dissatisfied with how the cabin crew had handled her ordeal. Air India Airlines was launched in 1932 by industrialist JRD Tata and nationalised in 1953. In 2021, Tata Group acquired the 90-year-old Air India from the Government of India for $2.4bn (INR 18,000 crore) and appointed Campbell Wilson as chief executive officer and managing director. The incident brought to the fore the customer management issues that Wilson had to address. First on the list of Air India’s turnaround plan was delivering “exceptional customer experience”. How was it going to achieve it because the Indian aviation ecosystem lacked infrastructure such as airports, airspace, competition and customer preference-based services? There was also shortage of pilots, engineers, technicians, air-traffic controllers and technocrats to occupy positions within security agencies and regulatory bodies. With Air India’s acquisition, the Tata Group had to find innovative solutions to deal with decades of internal neglect, non-performance and labour union problems. This case study is relevant to address real issues of customer experience, consumer psychology, reputation risk management and standard operating procedures in service management. Complexity academic level This case is suitable for both undergraduate and postgraduate level students of business management. It can also be used for training service personnel of aviation industry. Supplementary materials Teaching notes are available for educators only. Subject code CSS 8: Marketing

Influence of social media on organizational communication and organizational culture at the South African Social Security Agency in South Africa

Social media is a potent drive in the modern landscape of organizational dynamics, influencing cultural norms and communication styles. The purpose of this study is to investigate the complex effects of social media on organizational culture and communication. The paper explores how social media platforms have changed communication channels, interaction dynamics, and organizational culture, drawing on a mixture of previous research and pragmatic studies. A quantitative research paradigm was employed and a sample of 140 sample respondents was selected using simple random sampling. The sample respondents were employees at a selected South African Social Security Agency branch in South Africa. The results revealed that Facebook was the most used platform and that employees use social media for both work and non-work related purposes. The study concluded a positive and significant relationship between social media usage and social media enhancing the organizational culture (r = 0.227; p &amp;amp;lt; 0.05). Moreover, the study found no relationship between social media usage influencing employee behavior and social media restrictions impacting employee morale negatively (r = 0.036; p &amp;amp;gt; 0.05). The findings highlight valuable insights on the role of social media and its effect on organizational culture and communication. It is also evident from the results that social media usage presents opportunities and challenges for organizations. Hence, the paper concludes that organizations can use social media to create a communicative, flexible, and resilient organizational culture in digital time by recognizing the dynamics at work and taking proactive measures.

Analysis of Real Hospital Cost on Ina-Cbgs Rates for Cesarean Section Patients

A caesarean section is an artificial birth that is carried out by making a small incision in the abdominal wall and uterine wall, but the uterus must be intact and the fetus weighs &gt;500 grams. The high cost of a cesarean section has prompted the Indonesian government to launch the National Health Insurance (JKN) program as an implementation of the National Health Insurance (JKN) which has been regulated regarding to the payment patterns to advanced health facilities by applying Indonesian Case Based Groups (INA-CBG's). This study aims to determine the difference between real hospital cost rates and INA-CBGs rates for payment of claims by JKN participants for caesarean section inpatients at Dr. Soedomo Regional Hospital Trenggalek. The research method is analytical observation with a cross sectional approach which refers to the hospital's perspective by comparing the direct medical costs of BPJS’s (Social Security Agency on Health) participant patients and the INA-CBG's rates. The populations of this study were BPJS recipients of class I, II, III inpatients who received mild category of caesarean section at Dr. Soedomo Regional Hospital Trenggalek in 2020. The sample used in this study was medical record documents that met the inclusion and exclusion criteria. Purposive sampling method was used. In treatment of I, II, III classes, a significant difference was found between the average total direct medical costs of mild category of caesarean section patients (O-6-10-I) compared to the INA-CBGs rates. The treatment of class I had a difference of IDR 886,582. (p&lt;0.05). The treatment of class II had a difference of IDR 754,881. (p&lt;0.05) and the treatment of Class III, the difference obtained was IDR 1,109,368. (p&lt;0.05).

Economic evaluation of trastuzumab in HER2-positive early breast cancer in Indonesia: A cost-effectiveness analysis.

Trastuzumab has significantly enhanced the survival and prognosis of individuals diagnosed with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer. Considering its relatively high costs, we aimed to examine the cost-effectiveness of trastuzumab plus chemotherapy compared with chemotherapy alone in HER2-positive early breast cancer from an Indonesian healthcare payer's perspective. A Markov model was developed to project the lifetime health benefits and costs associated with trastuzumab treatment for a cohort of women with HER2-positive early breast cancer. Efficacy data and baseline characteristics in the base-case analysis were primarily derived from the 11-year results of the HERA trial. Costs were based on verified reimbursement data from Indonesia's Health and Social Security Agency (BPJS Kesehatan) of the year 2020. A scenario analysis was conducted with efficacy data based on the joint analysis from the NSABP B-31 and NCCTG N9831 trials, allowing for subgroup analysis by age at diagnosis. Univariate and probabilistic sensitivity analyses were conducted to assess the influence of parameter uncertainty. In the base-case analysis, the results indicated that the lifetime costs for trastuzumab plus chemotherapy and chemotherapy alone were US$33,744 and US$22,720, respectively, resulting in substantial incremental savings of US$11,024 per patient for the former. Trastuzumab plus chemotherapy also led to higher total quality-adjusted life years (QALYs) and life years gained (LYG), resulting in incremental cost-effectiveness ratios (ICERs) of US$6,842 per QALY and US$5,510 per LYG. In scenario analysis, the subgroup with an age at diagnosis <40 years old reflected the most cost-effective subgroup. Both the base-case and scenario analyses demonstrated cost-effectiveness with a willingness-to-pay threshold of three-times Gross Domestic Product (GDP). Sensitivity analyses confirmed the robustness of the findings and conclusions. In Indonesia, trastuzumab plus chemotherapy can be considered cost-effective compared to chemotherapy alone at a willingness-to-pay threshold of three times GDP, and it is likely most cost-effective in women <40 years of age.

A Profile of Influenza Vaccine Coverage for 2019-2020: Database Study of the English Primary Care Sentinel Cohort.

Innovation in seasonal influenza vaccine development has resulted in a wider range of formulations becoming available. Understanding vaccine coverage across populations including the timing of administration is important when evaluating vaccine benefits and risks. This study aims to report the representativeness, uptake of influenza vaccines, different formulations of influenza vaccines, and timing of administration within the English Primary Care Sentinel Cohort (PCSC). We used the PCSC of the Oxford-Royal College of General Practitioners Research and Surveillance Centre. We included patients of all ages registered with PCSC member general practices, reporting influenza vaccine coverage between September 1, 2019, and January 29, 2020. We identified influenza vaccination recipients and characterized them by age, clinical risk groups, and vaccine type. We reported the date of influenza vaccination within the PCSC by International Standard Organization (ISO) week. The representativeness of the PCSC population was compared with population data provided by the Office for National Statistics. PCSC influenza vaccine coverage was compared with published UK Health Security Agency's national data. We used paired t tests to compare populations, reported with 95% CI. The PCSC comprised 7,010,627 people from 693 general practices. The study population included a greater proportion of people aged 18-49 years (2,982,390/7,010,627, 42.5%; 95% CI 42.5%-42.6%) compared with the Office for National Statistics 2019 midyear population estimates (23,219,730/56,286,961, 41.3%; 95% CI 4.12%-41.3%; P<.001). People who are more deprived were underrepresented and those in the least deprived quintile were overrepresented. Within the study population, 24.7% (1,731,062/7,010,627; 95% CI 24.7%-24.7%) of people of all ages received an influenza vaccine compared with 24.2% (14,468,665/59,764,928; 95% CI 24.2%-24.2%; P<.001) in national data. The highest coverage was in people aged ≥65 years (913,695/1,264,700, 72.3%; 95% CI 72.2%-72.3%). The proportion of people in risk groups who received an influenza vaccine was also higher; for example, 69.8% (284,280/407,228; 95% CI 69.7%-70%) of people with diabetes in the PCSC received an influenza vaccine compared with 61.2% (983,727/1,607,996; 95% CI 61.1%-61.3%; P<.001) in national data. In the PCSC, vaccine type and brand information were available for 71.8% (358,365/498,923; 95% CI 71.7%-72%) of people aged 16-64 years and 81.9% (748,312/913,695; 95% CI 81.8%-82%) of people aged ≥65 years, compared with 23.6% (696,880/2,900,000) and 17.8% (1,385,888/7,700,000), respectively, of the same age groups in national data. Vaccination commenced during ISO week 35, continued until ISO week 3, and peaked during ISO week 41. The in-week peak in vaccination administration was on Saturdays. The PCSC's sociodemographic profile was similar to the national population and captured more data about risk groups, vaccine brands, and batches. This may reflect higher data quality. Its capabilities included reporting precise dates of administration. The PCSC is suitable for undertaking studies of influenza vaccine coverage.

Duty of Civilians Security Agencies that Suffer Losses Due to Civil Corruption

Objective: The media at the time focused on corruption practices in Indonesia's BUMN sector. Weak supervisory functions by the BUMN Supervisory Body have led to inefficient oversight of the Directorate, which is one of the sources of corruption in the BUMN sector. Therefore, in the event that a loss results from corruption, the BUMN's supervisory bodies are required to assume criminal accountability. Theoretical Framework: However, there are flaws and barriers in the application of criminal law that make it necessary to restructure the system of criminal responsibility against the supervisory bodies of the BUMN in order to impose criminal liability on them. Method: A court decision that brings criminal accusations against Indonesian firms provided the data for this study. After identification under consideration and court ruling, a legal technique is used to assess the data and identify a solution to the issue. Results and Conclusion: According to the study's findings, a supervisory body's failure to keep an eye on directors who engage in corrupt behavior is considered a "hole of omission," or a gap that puts the crime of inaction or passive acts in jeopardy. Implication of the Research: This research will have an impact on law enforcement related to criminal acts of corruption against State-Owned Enterprises (BUMN). Originality/Value: It is possible to create a just legal system where justice is the fundamental component of the law and the execution of the law itself by imposing criminal liability on supervisory authorities that fail to perform their oversight obligations against the Directorate in the management of BUMN.

Providing Complementary Food Made from Local Food for Toddlers in Indonesia: A Literature Review

Stunting is still a relatively high nutritional problem for toddlers in Indonesia. Even though the stunting rate is decreasing yearly, the downward trend is not fast enough to reach the target of 14% in 2024. The national team for accelerating poverty reduction in 2017 reported that access to nutritious food is still lacking because the price of healthy food is relatively high, which is one of the factors influencing stunting. Therefore, the government's strategy to accelerate stunting includes providing complementary food made from local food for toddlers and pregnant women to reduce stunting in Indonesia. This literature review aims to see how implementing the complementary food program made from local ingredients handles the stunting problem. A literature review is the result of a literature study through collecting and reviewing previous research. The data used are articles based on the Google Scholar database using the keywords stunting and local food, with a publication year limit of 5 years (2017 to 2023). Indonesia is the third largest country in the world regarding biodiversity (Food Security Agency). Various studies show that processed local Indonesian food has good nutritional content to fulfill children's dietary needs. Many regions have started to use local food as the leading choice of complementary food for toddlers and pregnant women. It is hoped that local food processing can be a nutritious food solution for improving children's nutrition in a sustainable manner in Indonesia.
