  • The surge in generic attacks execution against cipher text on the computer network has led to the continuous advancement of the mechanisms to protect information integrity and confidentiality. The implementation of explicit decision tree machine learning algorithm is reported to accurately classifier generic attacks better than some multi-classification algorithms as the multi-classification method suffers from detection oversight. However, there is a need to improve the accuracy and reduce the false alarm rate. Therefore, this study aims to improve generic attack classification by implementing two hybridized decision tree algorithms namely Naïve Bayes Decision tree (NBTree) and Logistic Model tree (LMT). The proposed hybridized methods were developed using the 10-fold cross-validation technique to avoid overfitting. The generic attack detector produced a 99.8% accuracy, an FPR score of 0.002 and an MCC score of 0.995. The performances of the proposed methods were better than the existing decision tree method. Similarly, the proposed method outperformed multi-classification methods for detecting generic attacks. Hence, it is recommended to implement hybridized decision tree method for detecting generic attacks on a computer network.

  • Currently, China's urban landscape is undergoing a gradual shift from incremental development to stock renovation. Furthermore, the planning and development objectives of urban communities have evolved from solely focusing on physical space construction to promoting sustainable development within a humanistic society. The current approach to community planning and construction, which emphasizes a singular dimension of residential life, overlooks the multifaceted aspects of community life and production. This oversight leads to a lack of attention to interpersonal relationships within the community, difficulties in establishing a connection between people and their environment, and numerous other issues. Consequently, this paper seeks to redefine the concept of sociality within community spaces by considering the continuum of time and space within communities. It aims to delineate the roles of "power" and "rights" within the community context, with a particular focus on everyday life, in order to reevaluate strategies and methods for fostering dynamic community development.

  • This study investigates the impact of corporate governance (defined as companies' ownership structure and board of directors' characteristics) on cash holdings in the context of Oman. This study leverages a quantitative panel pooled regression on a dataset of Omani non-financial firms from 2009-2015. The findings of this study are generally in line with the predictions of Agency Theory and Mentoring and Busyness Hypotheses. The analysis demonstrates that a large stockholder size has a significant positive relationship with cash holding. Meanwhile, a positive (but insignificant) relationship was also found between institutional ownership and cash holding. Furthermore, state ownership was found to exhibit a significant negative relationship with cash holding. In terms of the board of directors' traits, this study's findings suggest that board sizes have a positive (but insignificant) relationship with cash holding. Furthermore, busy and independent boards were found to have a significant positive relationship with cash holding. The above findings suggest that boards with such traits are less effective in providing oversight on managers' actions, which would then increase Omani non-financial firms' cash holdings.

  • In December 2019, coronavirus disease 2019 (COVID-19) was discovered in Wuhan, China. The disease was so severe that as early as 30 January 2020 COVID-19 was declared by WHO as a Public Health Emergency of International Concern. There have been a lot of concerns about conducting COVID-19 clinical researches scientifically and ethically in pandemic. This article is directed at addressing these issues from the perspective of IRB. First of all, the urgency of COVID-19 research requires prompt IRB process through efficient ethics review and oversight system. IRB should determine whether the risks that will be presented to human subjects are justified after assessing possible harm and anticipated benefits. The safety of subjects should not be compromised. Furthermore, informed consent should be voluntarily obtained by sufficient information in consideration of special circumstances during a pandemic.

  • This report describes a case of coinfection of Sphingomonas paucimobilis meningitis and Listeria monocytogenes bacteremia in a 66-year-old immunocompetent female patient. The patient had undergone traditional procedures, including acupuncture, which possibly caused the coinfection. During treatment with susceptible antibiotics for bacterial meningitis, she developed hydrocephalus on the third day. Consequently, the patient recovered with a mild neurological deficit of grade 4 motor assessment in both upper and lower extremities at discharge. S. paucimobilis and L. monocytogenes are rare pathogens in developed countries, occurring only during environmental outbreaks. S. paucimobilis meningitis is rarely reported. Hence, the various presentations of S. paucimobilis meningitis and the antibiotic regimen for its treatment are hereby reported, in addition to a review of other similar reported cases. This case is a possible traditional procedure-related infection. Appropriate oversight and training should be emphasized regarding preventive measures of this kind of infection. A team approach with neurologists and neurosurgeons is imperative in treating patients with hydrocephalus-complicated meningitis.

  • Unmanned aerial vehicles are gaining in popularity with the development of science and technology, and are being used for a wide range of purposes, including surveillance, rescue, delivery of goods, and data collection. In particular, the ability to avoid obstacles during navigation without human oversight is one of the essential capabilities that a drone must possess. Many works currently have solved this problem by implementing deep reinforcement learning (DRL) model. The essential core of a DRL model is reward function. Therefore, this paper proposes a new reward function with appropriate action space and employs dueling double deep Q-Networks to train a drone to navigate in indoor environment without collision.

  • The large increase in RTAs since the late 1980's has challenged the foundations of the multilateral trading system, and thereby has become an axis in the GATT/WTOsystem.While RTAs can be seen to be contradictory to the overall aim of the WTO, they were allowed for in Article XXIV of GATT conditional to certain provision. The failure of compliance and subsequently enforcement of these provisions could be seen as a serious flaw of Article XXIV since the inception of GATT system. Many elements of GATT Article XXIV are not clear and thus lead to divergent interpretations of its disciplines. This considerable divergence in opinions arise from both ambiguities throughout the provisions under GATT Article XXIV. In this regard, both economic and legal work is required to keep up with constantly changing nature of the world trading system. Further, global efforts are required to resolve another teething issue of WTO's problematic institutional framework on GATT/WTO's oversight and surveillance of RTAs. and thereby strengthen the multilateral trading system. Needless to say, theGATT/WTOframework has been essential in paving the way for RTAs while ensuring a more multilateral and liberal trading system. Consequently, global efforts should be made to restructure the WTO for the renewed multilateral trade liberalization in the GATT/WTO.

  • This paper describes effectiveness and characteristics of 3 P(point) task analysis as a new Ergonomic and Kansei design method for extracting user demand especially. The key point in 3 P task analysis is to describe the flow of tasks and extract any problems in each task. A solution of a problem means a user demand. 3 P task analysis cal eliminate an oversight of check items by examining the users' information processing level. The suers' information processing level was divided into the following three stages for problem extraction: acquirement of information ---> understanding and judgment ---> operation. Three stages has fourteenth cues such as difficulty of seeing, no emphasis, mapping for extracting problems. To link analysis results to the formulation of a product concept. I added a column on the right side of the table for writing the requirements (user demand) to resolve the problems extracted from each task. The requirements are extracted by using seventh cues. Finally 3 P task analysis was compared with group interview to make the characteristics of 3 P task analysis, especially extracting user demand, clear.
