Objective: To evaluate if a remote digital monitoring system added at the end of orthodontic treatment could positively influence the retention phase by reducing the occurrence of misfit of removable appliances, number of emergency appointments (EA), and orthodontic relapse. Methods: Twenty-seven patients who completed active orthodontic treatment were divided into the study and control groups. In addition to the standard chairside follow-up appointments at month 1 (T1), month 3 (T2), month 6 (T3), the study group patients were monitored using Dental Monitoring® with monthly intra-oral scans. Occurrence of misfit of removable retainers, number of EAs, and intercanine width change were recorded for both groups. Differences in EAs and retainer fit were assessed using the chi-square test. Intra-group and inter-group differences in the intercanine width were assessed with Friedman test and Mann–Whitney U test, respectively (α = 0.05). Results: The study group showed a significantly lower occurrence of misfit of removable retainers (p = 0.027) compared to the control group. No significant inter- and intra-group difference was found in the EAs and intercanine width change at each time-point. Conclusions: Integrating remote monitoring systems, such as Dental Monitoring®, to the retention phase of the orthodontic treatment may lower the occurrence of misfit of removable retainers. However, a small sample size and a short observation period limit the strength of this evidence. These preliminary results tentatively suggest that remote monitoring technologies may be beneficial, especially during the COVID-19 pandemic, when the regularity of in-office visits might be disrupted.

Objective: Planning of incisal position is crucial for optimal orthodontic treatment outcomes due to its consequences on facial esthetics and occlusion. A systematic summary of the proposed parameters is presented. Methods: Studies on Google Scholar©, PubMed©, and Cochrane Library, providing quantitative information on optimal central incisor position were included. Results: Upper incisors supero-inferior position (4–5 mm to upper lip, 67–73 mm to axial plane through pupils), antero-posterior position (3–4 mm to Nasion-A, 3–6 mm to A-Pogonion, 9–12 mm to true vertical line, 5 mm to A-projection, 9–10 mm to coronal plane through pupils), bucco-lingual angulation (4–7° to occlusal plane perpendicular on models, 20–22° to Nasion-A, 57–58° to upper occlusal plane, 16–20° to coronal plane through pupils, 108–110° to anterior-posterior nasal spine), mesio-distal angulation (5° to occlusal plane perpendicular on models). Lower incisors supero-inferior position (41–48 mm to soft-tissue mandibular plane), antero-posterior position (3–4 mm to Nasion-B, 1–3 mm to A-Pogonion, 12–15 mm to true vertical line, 6–8 mm to coronal plane through pupils), bucco-lingual angulation (1-4° to occlusal plane perpendicular on models, 87–94° to mandibular plane, 68° to Frankfurt plane, 22–25° to Nasion-B, 105° to occlusal plane, 64° to lower occlusal plane, 21° to A-Pogonion), mesiodistal angulation (2° to occlusal plane perpendicular on models). Conclusions: Although these findings can provide clinical guideline, they derive from heterogeneous studies in terms of subject characteristics and reference methods. Therefore, the optimal incisal position remains debatable.

Background Clinical guidelines recommend non-pharmacological interventions as the first line of treatment for agitation in dementia. One intervention that shows some promise as a treatment for agitation is essential oils. The objective of this study was to provide preliminary evidence of the effectiveness and feasibility of using topically-administered, individualized essential oil preparations for the alleviation of agitation in persons with dementia. Methods We conducted a 10-week pragmatic, cluster-randomized, placebo-controlled, pilot feasibility trial to compare the effectiveness of topically-administered, individualized essential oil preparations to control (placebo) preparations. Outcomes included frequency and severity of agitation, quality of life, frequency of antipsychotic medication use and physical restraint, incidence of adverse events, and trial feasibility. Participants with dementia and clinically significant agitation were recruited from five residential aged-care facilities across regional South Australia. Results Thirty-eight participants were randomized from five sites. Accounting for random effects, we found statistically significant differences between the intervention and control groups in Pittsburgh Agitation Scale (PAS) aberrant vocalization sub score, Cohen Mansfield Agitation Inventory (CMAI) verbally agitated sub score and CMAI total score at week 4, but not at weeks 8 (post-intervention) or 10 (follow-up). No significant time-group interactions were observed for other PAS/CMAI scores or sub scores, quality of life - Alzheimer's disease total score, or frequency of physical restraint or as-needed antipsychotic medication. No adverse events were reported in any group. Conclusions The study findings highlight some promising effects of topically-administered, individualized essential oil preparations for agitation in dementia, and indicate that a large multi-center, cluster-randomized controlled trial of this treatment is feasible.

Economic Viability of Smart Grid Cloud in India
Sandeep Mehmi,Amrit L Sangal,Harsh K Verma,Kulwinder Parmar 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.2
While the innovation and technology is modernizing the industry at rapid pace, the electrical power system is lagging behind the race and is being maintained in the same way for decades. Although the smart grid has ensured demand-response, reduction in transmission and distribution losses, and minimized theft, the inherent characteristic of enormous data generation has become a biggest concern. The absence of IT infrastructure in existing set up for handling unstructured data and huge capital investments are the major obstacles in complete success of smart grid in developing countries like India. However cloud computing has emerged as a solution to this problem. In this work, we have simulated cloud for smart grid on CloudSim and derived the cost for storing the smart grid data on cloud. The total cost of ownership (TCO) and return on investment (ROI) on building the datacenter with same configuration is also calculated using net present value (NPV), and compared with previous calculated cost. The results indicate that the initial cost of building a datacentre is $6673185 and ROI is 22.74 % in 7 years, which is low keeping in view the fact that during average design life of 10 years, a datacenter undergoes major equipment changes 3 to 4 times. On the contrary, outsourcing the same data on to cloud costs $2430720 annually, which is considered as an effective alternative. This analysis would be beneficial to developing countries like India in framing policies for storing the smart grid data on to the cloud which will further help in reaping the benefits of smart grid.

Hydrodynamic study of Activated Sludge Process (ASP) is important to optimize the reactor performance and detect anomalies in the system. Residence time distribution (RTD) study has been performed using LiCl as tracer on a pilot scale aeration tank (AT) and ASP, treating the pulp and paper mill effluent. The hydraulic performance and treatment efficiency of the AT and ASP at different operating parameters like residence time, recycle rate was investigated. Flow anomalies were identified and based on the experimental data empirical models was suggested to interpret the hydrodynamics of the reactors using compartment modelling technique. The analysis of the RTD curves and the compartment models indicated increase in back-mixing ratio as the mean hydraulic retention time (MHRT) of the tank was increased. Bypassing stream was observed at lower MHRT. The fraction of dead zone in the tank increased by approximate 20-25% with increase in recycle rate. The fraction of the stagnant zone was found well below 5% for all performed experiments, which was under experimental error. The substrate removal of 91% for Chemical oxygen demand and 96% for Biochemical oxygen demand were observed for the ASP working at a hydraulic mean residence time 39 h MRT with a 20% recycling of activated sludge.

Objective: Controlling the incisal inclination is fundamental in orthodontics. However, the relationship between the inclination prescription and its clinical outcome is not obvious, and the incisal inclination changes generated by different bracket prescriptions were investigated. Methods: Twenty-eight non-extraction dental Class II patients (15 females, 13 males; mean age = 12.9) were retrospectively analyzed. Patients were treated using passive self-ligating fixed appliances with three inclination prescriptions for maxillary incisors (high, standard, low), and two for mandibular incisors (standard, low). Clinical outcomes were compared among different prescriptions, and regression analysis was used to explain the effects of bracket prescriptions and to understand the prescription selection criteria (α = 0.05). Results: For maxillary central incisors, low and high prescriptions were related to linguoversion (p = 0.046) and labioversion (p = 0.005), respectively, while standard prescription maintained the initial dental inclination. Maxillary lateral incisors did not show significant changes. For mandibular incisors, low prescription led to linguoversion (p = 0.005 for central incisors, p = 0.010 for lateral incisors), while standard prescription led to labioversion (p = 0.045 for central incisors, p = 0.005 for lateral incisors). The factors affecting inclination changes were the imposed change and selected prescription, while prescription selection was influenced by the initial dental inclination and initial intercanine distance. Conclusions: The direction of correction of incisal inclination can be controlled by choosing a certain prescription, but the final inclination may show limited consistency with it. The amount of imposed inclination change was the most relevant predictor of the clinical outcome.
