Aligning Individual and Organizational R&D Goals for Self-Sustainability: Investigating Preferences of Researchers in Selected CSIR-Laboratories, India
No full textThis paper intends to explore the measure for aligning the goals of researchers towards achieving organizational R&D targets. The paper also explores the significance and ordering of R&D outputs and the factors that influence generation of R&D outputs, from the perspective of researchers working in the Indian public sector organizations.
Data was collected in five Indian R&D laboratories and Weighted Average Method; Spearman Correlation Coefficient and Rank Regression were utilized for the analysis.
The findings indicated that various groups of researchers prefer to target different R&D outputs and not all the factors are considered as equally significant in influencing the generation of R&D outputs. Further, the R&D organization should include preferred real factors while policy making for achieving collaborative efforts towards fulfilling organizational objectives. The set of selected R&D outputs and influencing factors were also ordered according to the average rankings given by the researchers.
The findings can help R&D managers to identify the expectations of the researchers and include their preferences in R&D Planning. The study could be extended to a larger dataset of researchers working in other government as well as private R&D organizations.
Hardly any studies were found that explored the preferences of researchers with respect to R&D outputs and influencing factors with respect to the Indian public sector R&D laboratories.

No full textEffect of Hesperidin as an Adjunct to Scaling and Root Planing on Clinical Parameters and Serum C-Reactive Protein Level in Chronic Periodontitis: A Randomized, Triple-Blind, Placebo-Controlled, Clinical Trial
No full textBackground:
Periodontitis is a chronic inflammatory disease that damages the supporting structures of the teeth, primarily caused by dental plaque containing Gram-negative bacteria. These bacteria trigger an inflammatory host response leading to tissue destruction.
Materials and Methods:
A total of 84 patients with moderate to severe chronic periodontitis were randomly assigned to either a test group receiving 500 mg of hesperidin daily or a control group receiving a placebo both alongside scaling and root planing (SRP). Clinical parameters including the gingival index (GI), sulcus bleeding index (SBI), probing depth (PD), and clinical attachment level (CAL) were evaluated at baseline, 3 weeks, and 6 weeks. Serum C-reactive protein (CRP) levels were measured at baseline and 3 weeks to assess systemic inflammation.
Results:
Of the 84 patients, 80 completed the study, with 60 males and 20 females. The test group showed significant reduction in serum CRP levels from baseline to 3 weeks (mean difference: 1.6300, P < 0.001), while the control group also showed a significant decrease (mean difference: -1.2730, P = 0.001). However, no statistically significant differences were found in clinical parameters (GI, SBI, PD, CAL) between the test and control groups at any time point. Intragroup analysis showed significant improvements in these parameters over time within both groups, indicating the effectiveness of SRP in managing clinical symptoms of periodontitis.
Conclusion:
Hesperidin significantly reduced serum CRP levels, indicating an anti-inflammatory effect, but did not result in significant improvements in clinical parameters compared to placebo
Comparative Evaluation of Clinical and Radiographic Changes Following Delayed Implant Placement in Mandibular Posterior Region with or without i-PRF Activation: A Split Mouth Clinical Study
No full textBackground:
Injectable platelet-rich fibrin (i-PRF) is prepared without anticoagulants having improved features such as increased fibroblast migration, proliferation, and tissue angiogenesis acceleration. When administered to titanium implants, i-PRF clings to the metal surface, generating a protein coating that impacts cellular activity required for osseointegration which aids in optimum and rapid osseointegration. The present study compared and evaluated the osteogenic properties of i-PRF in dental implant sites to determine the positive impact of i-PRF on osseointegration.
Methods:
A split-mouth clinical study design was used, involving ten participants with twenty sites of bilaterally missing mandibular molars. The subjects were divided into two equal treatment groups (N = 10): control group, where dental implants were placed without i-PRF activation, and test group, where i-PRF-activated dental implants were placed.
Results:
Both groups showed similar trends in plaque index and sulcular bleeding index. However, the test group exhibited significantly higher Implant Stability Quotient scores, indicating better stability. Peri-implant probing depth showed no significant difference between groups, but the test group had lower increase in probing depth. In addition, the test group showed superior wound healing and lower crestal bone loss changes compared to the control group.
Conclusions:
The findings of this study contributed to understand the effectiveness of i-PRF in enhancing osseointegration in dental implants, potentially improving clinical outcomes in implant dentistry

A Split-Mouth Study to Evaluate the Adjunctive Role of Guided Pocket Recolonization (GPR) to Non-Surgical Periodontal Therapy
No full textBackground:
The purpose of the study was to assess the effectiveness of prebiotic fructooligosaccharide (FOS) mixture and probiotic Saccharomyces boulardii (S. boulardii) when administered subgingivally as a supplement to scaling and root planing (SRP) in the treatment of chronic periodontitis. In addition, the N benzoyl DL arginine naphthylamide (BANA) test was used to examine the impact of probiotics on red complex organisms.
Materials and Methods:
Twenty systemically healthy participants with chronic periodontitis, with at least two periodontal pockets in each quadrant exhibiting probing depth (PD) ≥5 mm and clinical attachment level (CAL) ≥3 mm, participated in this split-mouth randomized controlled research. Two randomly chosen sites were chosen for each subject: one for testing, where SRP was followed by subgingival placement of the probiotic-prebiotic cocktail, and the other for control, where SRP alone was used. Assessments were conducted from baseline to 6 months later for the plaque index (PI), gingival index (GI), PD, and CAL. BANA was used to perform microbial assessments at baseline and at 1, 3, and 6 months. At certain intervals, the probiotic’s (S. boulardii) vitality was assessed both in vitro and in the pocket.
Results:
In both groups, there was a significant decrease in every clinical measure. A noteworthy enhancement was seen in the test group’s PI, GI, PPD, and CAL upon intergroup comparison in contrast to the control group. When comparing groups, it was shown that the test group’s BANA had significantly decreased after 3 and 6 months. While there was a significant difference and increase in in vitro vitality between the days, there was a significant difference and decrease in in vivo viability in the days that followed as compared to the day before.
Conclusion:
In comparison to SRP alone, subgingival administration of a probiotic-prebiotic mixture can be advantageous in non-surgical periodontal therapy for patients with chronic periodontitis and in managing the red complex organism’s recolonization over time
Evaluating Factors that Contribute to the Early Loss of Bone Around Submerged Implants Before they are Restored
No full textAim:
The aim of the present study was to examine various factors that may contribute to early crestal bone loss around submerged implants, prior to restoration.
Methods:
The research included a collective of 100 implants, procured from 60 participants. We allocated a total of 60 patients into two distinct groups: 20 individuals in the healthy group and 40 individuals in the ECBL group.
Results:
Out of the complete population, 56 people were unaffected by diabetes, while six persons were smokers. Systemic antibiotics were administered to almost all patients (98%) throughout the implantation procedure. The implant implantation consisted of 69% nonmolar implants and 31% molar implants.
Conclusion:
Engaging in a guided bone regeneration (GBR) operation before implant implantation has been shown to be a statistically significant factor in preventing early crestal bone loss (ECBL)
Implications of the Improvement of Teaching Quality for Professional Development (PD) of Academics at the Colleges of Applied Sciences (CASs) in the Sultanate of Oman
No full textThe Oman Accreditation Council (OAC), which is called later the Oman Academic Accreditation Authority (OAAA), designed a higher education institution (HEI) Quality Assurance (QA) framework for Omani public and private Higher Education Institutions (HEIs), starting with a quality audit process in 2008. The Colleges of Applied Sciences (CASs), as a public HEI, are required to ensure the quality of all services and activities to meet particular national standards (specified in the framework) in order to gain a HEI and programme certificate. In line with a quality audit scope, the quality of the fields of PD and related teaching quality should be ensured and enhanced by the promotion and contribution of the former field to the maintenance and improvement of the latter one.
The chief purpose of this study was to identify the uptake and implications of the growing requirement to improve teaching quality and the PD of academics at the CASs in the Sultanate of Oman especially in the context of the application of the QA framework. The study focused on examining the academics’ participation in professional development programmes (PDPs) and current perceptions of PD with respect to the improvement of teaching quality improvement at these colleges. The current study also dealt with a reorganization and prioritization of academics’ PD needs, barriers to effective PD, and factors to enhance PD of academics regarding teaching quality improvement in the colleges.
Based on the purpose and research objectives, the current study adopted both positivist (quantitative) and interpretive (qualitative) research paradigms. Because the study perused quantitative and qualitative data regarding certain variables, it chose a mixed-research design. The researcher designed survey questionnaire to collect quantitative data and a semi-structured interview and a focus group discussion to probe and interpret quantitative findings. After fulfillment of the validity and reliability measurements, a self-completion questionnaire was distributed to a stratified random sample of academics (170) over the six CASs. A total of 150 questionnaires (out of 170) were completed and returned and the response-rate reached 88.2%. The quantitative data was analyzed by appropriate analysis using the Statistical Package for Social sciences (SPSS), while the qualitative data was analyzed by appropriate qualitative analysis.
The findings of the study showed that the level of academics’ participation in PDPs to improve teaching quality in the last two years in the CASs seems to be unsatisfactorily low. The current perceptions of the PD situations in the colleges, relating to teaching quality improvement, signified a shortage in the number of available PDPs and/or a discouragement of academics’ participation in these programmes in the last two years. The study also revealed all the 22 PD needs of academics regarding the improvement of teaching quality are significantly demanded by participants; the higher rated needs focused on a development of ‘student centred’ skills, such as critical thinking and problem-solving skills.
Furthermore, the study illustrated that the highest significant perceived barriers to effective PD in the CASs, as related to teaching quality improvement, focus on a lack of a clear institutional PD policy and a lack of appropriately systematic PD plans. The study also revealed all 10 perceived factors to enhance PD regarding teaching quality improvement are very important. The most significant factors represented and stressed particular problematic issues (the high rated barriers) and a reduction of a heavy workload to enhance academics’ participation in PD regarding the improvement of teaching quality.
Conclusions drawn from the discussion of the findings of study include a lack of a clear PD policy at national and institutional levels and absence of a particular authority/unit concerning PD issues in Omani HEIs. The two problematic issues resulted in a lack of systematic and realistic PD plans in the CASs, involving a lack of academics’ involvement in PD plans, a misconnection of academics’ PD needs to PD, inappropriate facilities and resources allocation, and inappropriate evaluation processes of PD. In addition, the conclusions also include that PD of academics regarding the improvement of teaching quality in the colleges requires more attention and focus to manage particular significant issues perceived by participants as both barriers and potential facilitators relating to PD of academics.
Based on identified conclusions, particular implications for policy and practice to enhance PD to improve teaching quality were set at three levels: governmental, institutional, and individual. Moreover, achievements of the current study according to the research questions were identified and contributions of the study to the fields of PD, teaching quality, and the context of QA and quality audit in HE were addressed. Based on the findings and conclusions, particular directions and recommended issues were suggested to be studied by further research to benefit the enhancement of PD and related teaching quality improvement
