Characteristics of students’ learning behavior preferences — an analysis of self-commentary data based on the LDA model

How to better grasp students’ learning preferences in the environment of rapid development of engineering and science and technology so as to guide them to high-quality learning is one of the important research topics in the field of educational technology research today. In order to achieve this goal, this paper utilizes the LDA (Latent Dirichlet Allocation) model for text mining of the survey results on the basis of a survey on students’ self-perception evaluation. The results show that the LDA model is capable of extracting terms from text, fuzzy identifying groups of students at different levels and presenting potential logical relationships between the groups, and further analyzing the learning preferences of students at different levels for IT courses. Based on the student’s learning needs, this paper proposes recommendations for developing students’ learning effectiveness. The LDA method proposed in this paper is a feasible and effective method for assessing students’ learning dynamics as it generates cognitive content about students’ learning and allows for the timely discovery of students’ learning expectations and cutting-edge dynamics.

Quality-of-life improvement, psychosocial benefits, and patient satisfaction of patients undergoing orthognathic surgery: a summary of systematic reviews.

Function, aesthetics, and social and psychological well-being are all important aspects for patients undergoing orthognathic surgery. To evaluate the impact of orthognathic surgery on patient perception and quality of life before, during and after treatment. All relevant systematic reviews published up to 31st July 2020 have been searched via MEDLINE via OVID, Scopus, EMBASE, Web of Science, Cochrane Database of Systematic Reviews, PsycINFO, AMED (Allied and Complementary Medicine Database), and PubMed.Ongoing systematic reviews and grey literature were eliminated. A manual search was also undertaken, and no restrictions were applied to language or publication date. Systematic reviews involving dentofacial deformities related to systemic disorders, cleft lip and palate, facial trauma, and syndromes affecting cranial and dentofacial structures were excluded. Identification, screening, eligibility, and quality assessment [using the AMSTAR 2 tool (A Measurement Tool to Assess Systematic Reviews)] were performed by two authors independently. Data were synthesized qualitatively using thematic analysis. A total of 662 eligible studies were obtained of which 24 studies were selected for full-text evaluation, resulting in 12 eligible systematic reviews. Due to heterogeneity of data, quantitative analysis was not possible. Aesthetics and function are the main motives for seeking orthognathic surgery. Patient assessment before, during, and after orthognathic surgery is necessary for a thorough evaluation of self-perception and satisfaction throughout treatment. While psychological and social domains improved after orthognathic surgery treatment, the quality of life can deteriorate transiently during the pre-surgical orthodontic phase of treatment. A standardized assessment tool needs to be developed to assess quality-of-life changes consistently and provide comparable results. CRD42020199091.

Perception of quality of life by children and adolescents with cleft lip/palate after orthodontic and surgical treatment: gender and age analysis

BackgroundThe quality of life (QoL) of children and adolescents with cleft lip/palate (CL/P) has been shown to be a predictor of good psychosocial functioning in this population group. This study aimed to measure QoL, from the patient´s perception of change produced by the different surgical and orthodontic treatments carried out since early childhood, and if gender and age are modulating the outcome variables results.Materials and methodsA cross-sectional research study was carried out. The study included 60 patients with cleft lip, cleft palate, or cleft lip/palate, aged between 8 and 18, who were in orthodontic treatment and had undergone at least one surgery. They were asked to complete the Quality-of-Life Adolescent Cleft Questionnaire (QoLAdoCleft), which allows the assessment of the QoL through self-perception of improvement after surgical and orthodontic interventions. In particular, this questionnaire (administered only once), allows the evaluation of self-perception of QoL at the present time and before orthodontic and surgical treatment. This double assessment was carried out for the domains of physical, psychological, and social health. The results were analysed by looking at the interaction of gender and age.ResultsStatistically significant differences were found in the perception of the current QoL in comparison to the retrospective perception in all the dimensions considered. The perception of QoL improved in all cases. The results also showed a moderation of gender in the relation between perception of previous behaviour and social function and actual behaviour and social function.ConclusionThe results indicated that patients perceived their quality of life had improved as a result of the treatments received, with the highest effect sizes found in the physical health domain. Specifically, the improvement in QoL in behaviour and social function tended to be influenced to a greater extent by perception of previous QoL. In this sense, personalized preventative measures from holistic and biopsychosocial approaches are necessary.

Oral health self-perception evaluation using mandibular overdenture prosthesis in public health care

Objective: The aim of this study was to evaluate the impact on oral health in patients who used to have conventional lower denture and then started using a model of overdenture prosthesis for the purpose of its use in public health care. Methods: For this clinical trial study, 23 volunteers participated in the sample. To stabilize the prosthesis three implants were used and immediately loaded. Only one punch was needed for each implant to be installed, neither a flap nor suture was necessary. To evaluate the oral health self-perception the volunteers answered the OHIP-14 questionnaire twice, the first time before the treatment when they still used the conventional lower denture, and the second time within an average of 36 days after the use of the prosthesis stabilized by the implant/O-ring together. For statistical analysis, exploratory data analysis was initially performed and then the nonparametric Wilcoxon test was applied considering a significance level of 5%. Results: The average age of the sample was 57.6 years old (SD=9.0) with a minimum age of 43 and maximum of 74 years old. The results show a significant decrease in all domains after the treatment, functional limitation (p=0.0002), physical pain (p<0.0001), psychological discomfort (p=0.0002), physical disability (p< 0.0001), psychological disability (p=0.0008), social disability (p=0.0431) and handicap (p=0.0015). Conclusion: It was concluded that the model of overdenture prosthesis improved the volunteers oral health self-perception.

Do Facial Photographs Help In The Evaluation of Self Perception of Patients Towards Dentofacial Attractiveness?

Objectives: To determine whether exposure to pre-treatment facial photographs influenced patients self perception of dentofacial attractiveness to undergo more comprehensive treatment. Material and Methods: A total of 50 subjects of Indian population aged 18 years or older (25 in study group and 25 in control group) were selected. Photographs of the frontal and profile view of the face, both at rest and smiling were taken for each participant respectively. Only the study group subjects were given a printed copy of their own images to be examined at home between the initial observation period (T0) and 30 days later (T1). Each of the 50 subjects in the study completed a questionnaire at (T0) and (T1), regarding appreciation of their smiles and their facial profiles, as well willingness to undergo orthodontic treatment. Results: In the Study Group 56% of subjects responded with a lower opinion of their facial profiles at (T1) than (T0), and 36% and 32% of subjects were willing to undergo more comprehensive procedures to change the appearance of their smiles and profiles respectively. In the Control Group no statistically significant change was seen in questionnaire answers between (T0) and (T1). Conclusion: Unless exposed to photographs, patients generally are not aware of their facial profiles. Exposure to pretreatment smile and profile photographs influenced individual?s self-perception of dentofacial attractiveness and willingness to undergo more comprehensive orthodontic treatment.

Dental esthetic self-perception in young adults with and without previous orthodontic treatment.

The aim of this study was to determine which dental esthetic self-perception evaluation tool discriminated better between orthodontically treated or untreated Peruvian young adults. A total of 630 students were randomly chosen from the 2000 admitted in 2002 to a private university in Peru. Students undergoing active orthodontic treatment at the time of examination were excluded. Self-perceived dental esthetic appearance was evaluated through Standardized Continuum of Aesthetic Need, Oral Aesthetic Subjective Index Scale, and Visual Analogue Scale (VAS). A stepwise multivariate discriminant analysis was developed to classify orthodontic treatment according to the three evaluation tools. A total of 199 students (31.6%) reported a history of orthodontic treatment. Differences between orthodontically treated and untreated groups were found only for the mean VAS score (P < .001). Although three different approaches were used to evaluate dental esthetic self-perception, only VAS allowed the discrimination of the self-perceived dental appearance between orthodontically treated and untreated Peruvian university young adults. Similarities in the self-perceived dental appearance of treated and untreated groups reported in previous epidemiological studies could be explained because different evaluation instruments were used. Further studies are required to support current findings.
