Data Balance Algorithm Based on Histogram in MapReduce
Authors: Zhou Weibo , Zhong Yong , Wang Yang
Published: October 2018

MapReduce model is a typical distributed computing model, which is widely used in large-scale data processing, and its performance depends largely on the data distribution status. As the data content is often unbalanced, coupled with the storage of randomness, so MapReduce model prone to data skew problem in the calculation process. In order to solve this problem, this paper establishes a data histogram for the data block and the whole file through the improved parallel histogram parallelization algorithm based on MapReduce. According to the data block distribution, we can judge the data skew degree of each storage nodes and define the file equilibrium deviation value as the measure of data skew, and then the data balance algorithm is used to reduce the file equilibrium deviation value. The improved MapReduce-based data histogram parallel construction algorithm can adapt to various types of data application scenarios. In the process of building the histogram, the Map side only needs to transmit histogram statistics to the Reduce side without transmitting the contents of the file. The data transfer can be almost negligible. The data balance algorithm based on histogram employs greedy strategy, which can obtain a better approximate solution of the optimal solution of equilibrium distribution. After several experiments, compared with the random block distribution algorithm, the improved algorithm reduce about 40% of the file balance deviation value and achieves a better data balance performance.
Frequency Response Analysis of Fluid-Structure Interaction Vibration in Aircraft Bending Hydraulic Pipe
Authors: Quan Lingxiao , Sun Bingjiang , Zhao Jinsong , Li Dong
Published: October 2018

For the aviation bending pipe, the fluid-structure interaction 14-equation model is established, and the Laplace transform is used to solve the problem in the frequency domain. For the pipeline with a single elbow, the influence of bending parameters on the frequency response of the pipeline in the frequency domain is analyzed by using the 14-equation. At the same time, for pipelines containing two elbows, we analyze the influence of bending parameters on the natural frequency of the pipeline in different spans. In the end, the accuracy of the simulation is verified by the modal knocking test. Through the above analysis, we reach the following conclusion:the bending angle of the pipeline is greatly influenced by inherent characteristics, the smaller the bending angle, the higher the pipeline’s inherent frequency domain. However, the effect of bending radius will cause the change in length. Usually, the increase of bending radius leads to pipe length increasing, resulting in its inherent frequency decreasing.

Authors: Arantes Vitor , Uedo Noriya , Morita Yoshinori , Toyonaga Takashi , Nakano Yoshiko , Pedrosa Moises Salgado , Oda Ichiro , Saito Yutaka , Suzuki Haruhisa , Yamamoto Katsumi , Sato Yu , Draganov Peter V.
Published: October 2018

Background and study aims A post-endoscopic submucosal dissection (ESD) scar is expected to look homogeneous, however, some patients develop benign polypoid nodule scar (PNS). Incidence of PNS is unknown, yet these scars have direct clinical implications because they may render evaluation of post-ESD neoplastic recurrence difficult. Therefore, we reviewed the clinical experience of 5 ESD referral centers and evaluated their PNS incidence and clinical management.

Patients and methods This was a retrospective multicenter case series enrolling patients that underwent R0, curative gastric ESD from 2003 to 2015 in 5 academic centers. PNS was defined as ESD site nodularity with hyperplastic or regenerative tissue histology.

Results A total of 2275 patients underwent gastric ESD with endoscopy control and 28 patients (18 men/10 women) developed PNS for overall incidence of 1.2 %. Incidence of PNS ranged from 0.15 % to 11.4 % between centers. All patients that developed PNS had primary neoplastic lesions located in the distal stomach. Considering only lesions situated in the antrum (n = 912), incidence of PNS was 3.1 %. After mean follow-up of 43 months (range 6 – 192), no malignant recurrence in the PNS has been identified. In five patients (17.8 %) PNS disappeared after a mean of 18 months.

Conclusion PNS occurs exclusively after ESD in the distal stomach in approximately 3.1 % of patients. Although PNS appearance can be concerning, no malignant recurrence was observed after curative R0 resection. Therefore, PNS should be viewed as a benign alteration that does not require any type of intervention, other than endoscopic surveillance.

Authors: Razavi Toktam , Kouhsari Shideh Montasser , Abnous Khalil
Published: October 2018

Diabetes mellitus is a complex metabolic disease around the world that is characterized by hyperglycemia resulting from impaired insulin secretion, insulin action, or both. MicroRNA-29a is an important regulator of insulin signaling and gluconeogenesis pathways through IRS2, PI3K and PEPCK expressions which up regulates in Diabetes. Morin is a substantial bioflavonoid which has insulin mimetic effect, and interacting with nucleic acids and proteins. In this study HepG2 cells, were exposed to high glucose to induce diabetic condition. We have determined whether high glucose stimulation might promotes miR-29a expression level in HepG2 cells and subsequently evaluated the Morin treatment effects on this state. In HepG2 cells, high glucose increases miR-29a expression level and decreases its target genes, IRS2 and PI3K expression, and increases associated downstream gene in gluconeogenic pathway, PEPCK. Morin treatment down regulates miR-29a expression level and improves insulin signaling and glucose metabolism. To confirm the inhibitory effects of Morin on miR-29a, we have transfected cells with mimic and inhibitor-miR-29a. This study for the first time identifies that Morin improves diabetic condition through down regulation of the miR-29a level, and suggest that this new inhibitor of miR-29a may be a useful biomedicine to treat diabetes.

Introduction The routine use of preoperative endoscopy for patients undergoing bariatric surgery is controversial. Although many surgeons find it unnecessary, others still consider it a mandatory tool in preoperative assessment.

Patients and methods We reviewed the medical records of all patients who had undergone preoperative endoscopy before bariatric surgery in Rashid Hospital between January 2013 and June 2016. The patients were divided into three groups: Group 0 included patients with normal endoscopy; Group 1 included patients with abnormalities that did not affect the timing or type of procedure; Group 2 included patients with abnormalities that had a direct impact on the procedure.

Results The files of 1473 patients were reviewed. Endoscopy results were not present in 195 files, so those patients were excluded, and the remaining 1278 files were included. The mean age of patients was 41.3 ± 12.7 years, 61 % were female and 39 % were male. The mean body mass index (BMI) was 43.7 ± 8 kg/m2. Endoscopy was normal in 10.6 % of patients and abnormal in 89.4 %. The most common abnormalities were gastritis, positive Campylobacter-like organism test (CLO test), gastroesophageal reflux disease (GERD) with esophagitis and hiatal hernia. Group 0 included 10.6 % of patients (n = 135), Group 1 included 25.6 % of patients (n = 327), while Group 2 included 63.8 % of patients (n = 816).

Conclusion Routine endoscopy seems to play an important part in the preoperative preparation of patients planned for bariatric surgery in the Middle East population. Further studies or meta-analysis could help in building up clear solid evidence and guidelines that could be approved by international bariatric associations with regard to indications for preoperative upper endoscopy in bariatric patients.

Recommendations

A new objective for the European Society of Gastrointestinal Endoscopy (ESGE) is to develop long-term partnerships with African countries. For this, an International Affairs Working Group (IAWG) was formed.

In conjunction with the World Endoscopy Organization (WEO), ESGE conducted a survey of gastrointestinal (GI) endoscopy in Africa.

Survey results showed that many African countries have few GI endoscopy centers with adequate resources. Barriers to the development of endoscopy services include a shortage of endoscopists who have undergone advanced endoscopy training, and a lack of equipment and basic infrastructure.

Diseases related to infectious etiology are more prevalent than neoplastic diseases in Africa. Any development of endoscopy services needs to consider the local prevalence of diseases for which GI endoscopy is required, as well as the availability of resources.

The IAWG will initiate a cascade approach to identify and adapt ESGE guidelines for local use. The guidelines will consider the level of resources available for each intervention, as well as cost, infrastructure, and training, and will be approved by consensus of local experts who are representative of different African areas.

Suitable centers in African countries will be identified, and in future will be developed into WEO/ESGE training centers, to provide local training in both basic and advanced endoscopy according to the needs of the area.
Ideal Facial Relationships and Goals
Authors: Bueller Hope
Published: October 2018

Analysis of the face is an essential component of facial plastic surgery. In training, we are taught standards and ideals based on neoclassical models of beauty from Greek and Roman art and architecture. In practice, we encounter a wide range of variation in patient desires and perceptions of beauty. Our goals seem to be ever shifting, yet our education has provided us with a foundation from which to draw ideals of beauty. Plastic surgeons must synthesize classical ideas of beauty with patient desires, cultural nuances, and ethnic considerations all the while maintaining a natural appearance and result. This article gives an overview of classical models of facial proportions and relationships, while also discussing unique ethnic and cultural considerations which may influence the goal for the individual patient.
Crestal Bone Preservation with Platform Switching
Authors: Kumar Manjit , Chopra Megha , Singh Udey
Published: October 2018

New implant designs have appeared in the literature which claim that certain modifications may be helpful for maintaining crestal bone levels and consequently preserving normal soft tissue contours. Maintenance of soft tissue has been shown to depend on preservation of bone surrounding the implant. In order to achieve this goal, each step of the treatment must be managed carefully. This requires knowledge of pre-surgical treatment planning, site development, implant positioning, soft tissue management, provisionalization and prosthetic management.

Placement of a smaller diameter abutment on a large diameter implant platform (platform switching) has been proposed as an effective way to control circumferential bone loss around dental implants. The purpose of this paper is to evaluate the literature from an evidence based point of view regarding implant design modifications for preserving soft and hard tissue around implants.

Authors: Rathore Bhumika , Sadasivan Sireesha , Bhardwaj Vinay
Published: October 2018

Background: The inequity of oral health services persist due to inadequate dentist to patient ratio in the peripheral areas. The possibility of management of more number of patients lies within an efficient work force, in order to render oral health services in a well-organised manner. Objectives: The research was taken up with the primary objective of determining the most time efficient manpower in a peripheral dental unit. Secondary objective was to determine the time spent in each treatment procedure in proportion to total time involved in direct patient care. Third objective, was to recommend an appropriate range of sample for further similar studies using observatory methodology in peripheral centres. Methodology: Work measurement was done for the postgraduate and the undergraduate students for the treatments performed by them in the unit. Participatory observations were made on randomly selected days, and timings were recorded using standardised stop watch. Descriptive analysis was performed for the data obtained using Statistical Package for Social Science (IBM Corp. Released 2010. IBM SPSS Statistics for Windows, Version 19.0. Armonk, NY: IBM Corp.). Results: Mean timing was found to be highest for all treatment procedures amongst graduates when compared to the postgraduates and maximum proportion of time was spent for extractions amongst all the treatments performed. Conclusion: Availability of speciality services will help the hospitals render more proficient services to the rural masses.

Objective: The aim of the study was to determine the clinical outcome when polyglactin 910 membrane was used to treat 30 patients with isolated buccal millers class II gingival recessions. Materials and Method: Thirty subjects were selected with a chief complaint of hypersensitivity or denuded roots; all were willing to participate in the clinical study. Inclusion criteria were the presence of 4 mm or more of buccal millers class II gingival recession, a lack of contraindications for periodontal surgery. Results: The mean reduction in clinical recession from baseline to 6 months postoperatively was 2.47 ± 0.86 mm, i.e, 54%, which was statistically significant. There was a definite reduction in Pocket Depth, from a mean at baseline of 1.53 ± 0.63mm to a mean of 1.07 ± 0.26mm at 6 months. Conclusion: The use of GTR is a suitable alternative to the use of patient's own palatal masticatory mucosa. Polyglactin 910 as a GTR resorbable membrane gives the clinician another tool that provides acceptable root coverage.

Published: October 2018

TMDs have a multifactorial etiology varying from bruxism, psychological illness and traumatic injuries from mastication, extreme mouth opening, or faulty dental restorations. The present case study highlights the importance of right diagnosis of the patients problem as this forms the foundation to formulate a comprehensive treatment plan which further ensures the right solution to the stated patient problem along with long term maintenance of healthy stomatognathic system. An hard occlusal splint has been indirectly fabricated on the semiadjustable articulator. Occlusal splint used in treatment of TMDs is designed to provide even and balanced Occlusal contacts without forcefully altering the mandibular rest position or permanently altering the dentition. One case of fabrication of mandibular occlusal splint and its therapeutic role is discussed in this case report. The splint successfully relieved the patient TMD signs and symptoms, when used over four months.
Correction of the Crooked Nose
Authors: Newberry C. , Mobley Steven
Published: October 2018

Successful management of the crooked nose can be a formidable task and requires a systematic approach that begins with an understanding of the patients' aesthetic desires, expectations, and functional symptoms. Dividing the nose into thirds and organizing a plan to correct each region individually can simplify the preoperative planning. There are two broad philosophical strategies of surgical management: engineering (reconstructive) and artistic (camouflaging). While the camouflaging technique is helpful for minor asymmetries, protrusions, and depressions, the engineering approach is best for more extreme corrections. The surgeon must be skilled in both approaches as either one or a combination of the two may yield the best results. Once corrected, postoperative care is essential to obtain optimal outcomes.
