The Underutilization of Lifestyle Modifications in Primary Care Medicine

Jean-Marc Lucas(Jean-Marc Lucas ),Karl F. Kozlowski(Karl F. Kozlowski ) 사피엔시아 2019 Exercise Medicine Vol.3 No.-

Chronic disease accounts for the majority of deaths in the United States and is often attributed to obesity. A sedentary lifestyle and poor nutrition are primary contributing factors to the development of obesity and thus chronic disease. Primary care providers are optimally positioned to prescribe exercise and nutrition (lifestyle medicine) as a treatment for chronic disease. Unfortunately, this opportunity seems to be regularly lost. Primary care providers often rely too heavily on weight loss pharmaceuticals and bariatric surgeries to treat obesity. This treatment approach however also does little to prevent and treat the accumulation of chronic diseases. The purpose of this review was to evaluate the efficacy of conventional medical weight loss treatments and determine why primary care providers may not prescribe exercise and nutrition more frequently. Our findings suggest that some primary care providers may be uncomfortable prescribing lifestyle medicine as they receive little formal education in this field. In conclusion, prescription of exercise and nutrition by primary care providers may elicit greater long-term weight loss than current medical weight management practices. Medical management is most likely effective when combined with lifestyle medicine. We propose that primary care providers be better trained in lifestyle medicine through their formal and clinical education. Rates of chronic disease accumulation may potentially decrease if providers prescribe lifestyle medical treatments more frequently.

This paper proposed to elaborate a navigation system for an autonomous mobile robot, able to deviate from obstacles, from the study and application of Fuzzy Logic. With the algorithm in operation, it was verified that the Fuzzy logic offers a smoother transition in the movements. In order to validate the efficiency of the navigation system created, simulations were performed with the robot according to the rules inserted in the Fuzzy controller, where the input values of the sensors and the output values in the PWM of the board were analyzed. The results obtained were consistent with the responses given by the simulation in MatLab, following the same trend of behavior. With the realization of this project, it was concluded that the Fuzzy methodology presents a solution to the problems of navigation in real environments, allowing to implement a controller for an autonomous robot that can deflect obstacles avoiding their collision. One of the problems encountered is the angle of actuation of the ultrasonic sensors. This type of sensor works with an angle of actuation of 15◦, which leaves the robot with a low vision area in the use of three sensors. As a result, there may be no reading on objects entering zones without detection, leading to a collision with these obstacles. The responses were satisfactory, following the same trend behavior of the simulations of the Fuzzy controller.

Purpose: To compare the diagnostic ability of undergraduate dental students to detect maxillary sinus abnormalities in panoramic radiographs (PR) and cone-beam computed tomography (CBCT). Materials and Methods: This was a retrospective study based on the evaluation of PR and CBCT images. A pilot study was conducted to determine the number of students eligible to participate in the study. The images were evaluated by 2 students, and 280 maxillary sinuses were assessed using the following categories: normal, mucosal thickening, sinus polyp, antral pseudocyst, nonspecific opacification, periostitis, antrolith, and antrolith associated with mucosal thickening. The reference standard was established by the consensus of 2 oral radiologists based on the CBCT images. The kappa test, receiver operating characteristic curves, and 1-way analysis of variance with the Tukey-Kramer post-hoc test were employed. Results: Intraobserver and interobserver reliability showed agreement ranging from substantial (0.809) to almost perfect (0.922). The agreement between the students’ evaluations and the reference standard was reasonable (0.258) for PR and substantial (0.692) for CBCT. Comparisons of values of sensitivity, specificity, and accuracy showed that CBCT was significantly better (P<0.05). Conclusion: CBCT was better than PR for the detection of maxillary sinus abnormalities by dental students. However, CBCT should only be requested after a careful analysis of PR by students and more experienced professionals.

Exploring Critical Pedagogy and Choice in EAP Material Development: A Case Study

Lucas Kohnke 아시아테플 2019 The Journal of Asia TEFL Vol.16 No.4

In recent years, English language teaching materials, textbooks, videos and websites that facilitate the learning of language, which have grown in number, have tended to cover safe, non-controversial topics using the banking model (in Paulo Freire’s terms). Often these topics did not engage learners either affectively or cognitively. This study addressed the lack of choice and localised context in an English for Academic Purposes course in Hong Kong by incorporating learners’ choices of topic and digital stories into the course. The findings indicated that learner autonomy over topic and the affordances of digital delivery stimulated students to feel ownership and relevance to their local community. The results suggested that by incorporating the principles of critical applied linguistics, second language learners and students can co-construct material and knowledge and represent what they find personally meaningful, which may lead to social changes in society.

HYPERSURFACES IN 𝕊⁴ THAT ARE OF L_k-2-TYPE

Lucas, Pascual,Ramirez-Ospina, Hector-Fabian Korean Mathematical Society 2016 대한수학회보 Vol.53 No.3

In this paper we begin the study of $L_k$-2-type hypersurfaces of a hypersphere ${\mathbb{S}}^{n+1}{\subset}{\mathbb{R}}^{n+2}$ for $k{\geq}1$ Let ${\psi}:M^3{\rightarrow}{\mathbb{S}}^4$ be an orientable $H_k$-hypersurface, which is not an open portion of a hypersphere. Then $M^3$ is of $L_k$-2-type if and only if $M^3$ is a Clifford tori ${\mathbb{S}}^1(r_1){\times}{\mathbb{S}}^2(r_2)$, $r^2_1+r^2_2=1$, for appropriate radii, or a tube $T^r(V^2)$ of appropriate constant radius r around the Veronese embedding of the real projective plane ${\mathbb{R}}P^2({\sqrt{3}})$.

PURPOSE. The aim of this study is to evaluate the influence of repeated surface treatments on wettability and surface roughness for zirconia surface and bond strength of zirconia-based ceramics to resin cement. MATERIALS AND METHODS. Seventy blocks (10 × 10 × 3 mm) of zirconia-based ceramics were fabricated and divided into two groups according to the surface treatments: (A) 110 μm Al2O3 airborne-particle abrasion and (R) 110 μm silica modified Al2O3 airborne-particle abrasion. At stage 2, each group was subdivided into 5 groups according to the surface retreatments: (a) 110 μm Al2O3 airborne-particle abrasion, (r) 110 μm silica modified Al2O3 airborne-particle abrasion, (D) diamond bur, (Da) diamond bur + 110 μm Al2O3 airborne-particle abrasion, and (Dr) diamond bur + 110 μm silica modified Al2O3 airborne-particle abrasion. Cylinders of self-adhesive resin cement were cemented onto each treated ceramic surface and subjected to micro-shear bond strength test. Additional specimens were prepared for roughness and wettability analyses. The data were subjected to t-test and One-way ANOVA followed by Tukey’s post hoc test (α=.05). RESULTS. At stage 1, group R presented higher bond strength values than group A (P=.000). There was a statistically significant increase of bond strength at stage 2 for group A (P=.003). The diamond bur influenced the surface roughness, increasing the values (P=.023). Group R provided better wettability. Regardless of the applied surface treatment, most of failures were adhesive. CONCLUSION. The combination of application and reapplication of Rocatec Plus showed the best results of bond strength. Surface retreatment and recementation might be an indicated clinical strategy.

Building Relatedness Through Hashtags: Social Influence and Motivation Within Social Media-Based Online Discussion Forums

( Lucas John Jensen ) 한국교육공학회 2016 한국교육공학회 학술대회발표자료집 Vol.2016 No.1

In the last two decades, the mainstream growth of the Internet has led to transformative change in education, particularly higher education, as the Internet has provided new opportunities for learning online and at a distance (Allen & Seaman, 2010, Shea & Bidjerano, 2010). Commensurate with this has been a rise in the sphere of online activity known as social media - networks of users tied together via Web 2.0-based applications that offer users an opportunity to generate and share content of their own (Kaplan & Haenlein, 2010). A recent development in the world of social media is the introduction of so-called "hashtags," represented symbolically by the "#" or "pound sign" symbol, joining use together, even if they don``t know each other (Ebner, Beham, Costa, & Reinhardt, 2009, Page, 2012). Easy to create, hashtags have become a unique way to experience global events, have political debates, or meet people with similar interests. For some time, online discussion forums have been a preferred pedagogical method of generating and facilitating discussion in online education and classrooms with online components (Mazzolini & Maddison, 2003, Rossman, 1999). Online discussion forums are typically administered through the built-in tools of a Learning Management System (LMS). Although LMSs offer basic tools for class instruction and management, there is debate as to the limits of their pedagogical value (Hong, 2008, Martindale & Wiley, 2004). The pedagogical concept of Personal Learning Environments (PLEs) challenges the dominance of LMS usage in online courses, bringing a student-centered and bottom-up perspective to online education. The thinking behind PLEs is that instruction should be situated in an environment more congruent with the learners`` typical technology usage for their personal lives, such as social media (Attwell, 2007). The purpose of this presentation is to share the research results of a study investigating the motivation of student``s participation in an online discussion forum when moved from an LMS to a class Twitter hashtag group. Twitter activity was analyzed, and respondents were surveyed on their intrinsic motivation in online discussions, social influences on their social media choice, and if their previous experience with social media affected motivation.
