Modelling a Trusted Mechanism for Knowledge Sharing

Knowledge sharing has been identified as a major focus area for knowledge management. Efforts are made with a view to identify the most effective ways to share knowledge, as a step towards improving organizational performance. In this striving, various factors have been identified as impediments for knowledge sharing, including inadequate organizational structures, sharing unfriendly organizational cultures, and denominational segregation. Related problems may occur when information systems, such as intranets, distributed libraries, document management systems, or groupware applications, are introduced to support knowledge sharing. The extensive use of the IT&C has only added new questions on how to address issues of trust within the present knowledge -rich environment. This paper proposes a new way of approaching knowledge sharing in the context of information and communication technology development. The study provides an overview of the manner and extent in which information assurance concepts of integrity, authenticity, availability, non-repudiation and access-control may be employed to ensure a trusted and effective knowledge sharing process.knowledge sharing; sharing policy; access control; trusted knowledge sharing; barriers in knowledge sharing.

The Challenge of Ensuring Business Security in Information Age

Every day, thousands of businesses rely on the services and information ensured by information and communication networks. As the dependence on information systems grows, so the security of information networks becomes ever more critical to any entity, no matter if it is a company or a public institution. The asymmetrical threat posed by cyber attacks and the inherent vulnerabilities of cyberspace constitute a serious security risk confronting all nations. For this reason, the cyber threats need to be addressed at the global level. Given the gravity of the threat and of the interests at stake, it is imperative that the comprehensive use of information technology solutions be supported by a high level of security measures and be embedded also in a broad and sophisticated cyber security culture. This paper provides arguments regarding the need to implement coherent information security policies at national level, based on cooperation between public and private sectors and in coordination with international initiatives in the field. Since information security is vital for developing and running an efficient business, this study may constitute a strategic approach to improve the information security posture of Romanian organizations.information security; information security risk management; security threats; confidentiality; integrity; availability.

AGROCHEMICAL CHARACTERIZATION OF A NEW RANGE OF FOLIAR FERTILIZERS

In the context of a competitive and sustainable agriculture, the development of novel fertilizers with foliar application is always a challenge for both producers and users. Worldwide, a major trend in the research, development and production of organic substances fertilizers with growth-stimulating role is noticed. Thus, these new fertilizers formulas can be used in both, conventional and organic farming (especially to protect crops from climatic stress factors and to prevent or correct nutritional deficiencies). The production of fertilizers that contain natural organic compounds embedded in NPK matrix structures has increased. As organic substances are used protein hydrolysates, amino acids and algae extracts.In this study, in order to obtain a new range of fertilizers we defined the composition of a NPK matrix with meso- and microelements (Fe, Cu, Zn, Mn, Mg, S, Co, Mo) that was subsequently embedded with protein hydrolysate of animal origin (composed of peptides, ureide and amino acids) respectively, protein hydrolysate of vegetal origin.The new developed fertilizers were characterized and tested in the National Network for Fertilizers Testing in order to be licensed for agriculture use. The experiments were carried out for two years on different crops by foliar application in comparison to a similar NPK matrix. The obtained results showed significant production yields (in comparison to the non-fertilized control) ranging from 20% to 40% (statistically insured), as well as changes in the photosynthesis and mineral nutrition processes

Efficiency of foliar fertilization on wheat production in conventional and conservation agriculture

The paper presents the leaves fertilization influence upon wheat yield in two experiments carried out in conventional agriculture and conservative systems. The experimental fields comprised 6 leaves fertilizers variants and a control and were laid out at SCDA Teleorman on a Haplic Phaeozem. Two treatments were applied with 1.25% leaves fertilizer on a N90P40K0 agrochemical background proceeded from a complex 20-20-0 fertilizer, in the autumn, before sowing, and 50 kg N/ha Nitrocalcar, applied in the spring. Leaves fertilization, applied in the conservative system experiment, didn’t bring forth a significant yield increase as compared to the control. Significant and distinctly significant increases of the wheat yield were obtained in the conventional agriculture system, from 5,795 kg/ha in the control up to 7,373 kg/ha in the Nutrifert S variant. The average conventional agriculture yield (6,978 kg/ha) was higher than the conservative agriculture one (5,457 kg/ha) by 27.8%

Biostimulation with low-level laser therapy and its effects on soft and hard tissue regeneration. Literature review

Objective. Low-Level Laser Therapy encourages the healing process, reduces inflammation and pain. The aim of this study is to identify the impact of Low-Level Laser Therapy on tissue regeneration with special attention to hard tissues and to compare the effect of several wave lengths in the proliferation and differentiation of cells. Methods. The keywords used were “bone regeneration”, “laser therapy”, “photobiomodulation” OR “bio-stimulation”, “Low-Level Laser therapy” OR “LLLT”, “osteoblast proliferation” AND “differentiation”. Results. The bio-stimulation with Low-Level Laser Therapy also seems to interfere with the osseous integration of implants, by increasing its adherence on the bone-implant surfaces. Evidence has shown that Low-Level Laser Therapy influences the cellular proliferation and differentiation. Conclusions. Low-Level Laser Therapy is a promising therapy in the field of regeneration, but further studies are needed in order to define the standard protocol

Presentation of Financial Statements According to IPSAS - a Challenge for Professional Accountants

The International Public Sector Accounting Standards (IPSAS) is an important step in public sectoraccounting reform. Problems arising in the context of adopting a common language through IPSAS aremultiple and not easy to prove their usefulness, advantages and disadvantages of using them, so aim will bethe countries' agreement to accept and adopt these regulations. The preparation of financial statements is acomplex process of aggregating data to form economic and financial indicators. Content and preparation ofthe financial statements differ by type of institution, according to their kinds, depending on how their fundingand business profile. The financial statements of public institutions are particularly broad, complex andlengthy, and the information it provides can often be interpreted only by the professional accountant. Theprofessional accountant is the only one capable of ensuring providing appropriate information to users thatthey base their decisions on the allocation of funds

OPTIMIZING ORTHOPEDIC OUTCOMES: THE CRUCIAL ROLE OF PREOPERATIVE DENTAL ASSESSMENT IN HIP AND KNEE ARTHROPLASTY – NARRATIVE REVIEW

Introduction: In the context of orthopedic surgery, particularly knee and hip replacements, the role of dental health often goes unnoticed. This literature review explores the significance of dental clearance prior to knee and hip arthroplasty, highlighting the role of preoperative dental evaluation in reducing the risk of Periprosthetic Joint Infections (PJI). Materials and Methods: The review involved a comprehensive examination of various studies and reports discussing the prevalence of dental pathology in patients requiring joint arthroplasty and the risk factors for PJIs. Additionally, it included the development of a patient selection algorithm and a questionnaire designed to identify individuals at higher risk of dental-related complications. Results and Discussions: This section would discuss the findings of the literature review, particularly focusing on the effectiveness of preoperative dental clearance in mitigating the risks of PJIs. It would also analyze the results obtained from the application of the patient selection algorithm and questionnaire, emphasizing their role in streamlining the preoperative evaluation process. Conclusions: The review concludes by emphasizing the necessity of comprehensive oral health evaluations for patients undergoing hip and knee arthroplasty, especially for those with multiple comorbidities or at higher risk of dental infections. The importance of integrating dental assessments into the perioperative management of joint arthroplasty patients is also highlighted

DENTAL ANTIBIOTIC PROPHYLAXIS IN TOTAL JOINT REPLACEMENT: AN UPDATED REVIEW OF GUIDELINES AND CLINICAL STUDIES

Aim of the study: This review evaluates the necessity and effectiveness of antibiotic prophylaxis in preventing prosthetic joint infections (PJI) following dental procedures in patients with joint implants.Material and methods: An extensive literature review was conducted, focusing on studies evaluating the link between dental care and PJI. Sources included PubMed and other databases, using terms such as dental care, joint prosthesis, and antibiotic prophylaxis. The review spanned papers from 2003 to 2023, with a focus on hip and knee joint replacements and dental procedure-related prophylaxis guidelines.Results: The review found that the prevalence of dental pathology in patients with total hip arthroplasty (THA) or total knee arthroplasty (TKA) varied significantly. Studies indicated no significant benefit of antibiotic prophylaxis in reducing PJI risk post-dental procedures. Furthermore, the incidence of PJI was not significantly different in patients receiving antibiotic prophylaxis compared to those who did not. It was observed that routine activities, such as chewing and brushing, contribute more to bacteremia and potential joint infection than dental procedures themselves.Conclusions: The evidence suggests that antibiotic prophylaxis for dental procedures in patients with joint prostheses is not universally beneficial and should not be routinely recommended. Emphasis on individual risk assessment, maintenance of good oral hygiene, and adherence to evidence-based guidelines is paramount. The study advocates for personalized approaches to PJI prevention, aligning with the goals of antibiotic stewardship and patient safety
