Intraocular Pressure Fluctuation: Is It Important?

Elevated intraocular pressure (IOP) is a major risk factor for the development and progression of glaucoma. Previous prospective, randomized, long-term studies have demonstrated the strength of IOP reduction in slowing the progression of disease. It is well known that IOP is not a fixed value but fluctuates considerably over time. Although there have been some studies on IOP fluctuation and the progression of glaucoma, whether IOP fluctuation is an independent risk factor for glaucomatous damage and disease progression remains controversial. In this article, we reviewed the definition of IOP fluctuation, and both the evidence and the speculation for and against the effect of IOP fluctuation on glaucoma progression. Although conclusions seem to vary from study to study, we considered that different studies examined different groups of patients, at different stages of disease, and at different IOP levels. Our conclusion is that these apparently disparate results are not conflicting, but rather can be viewed as complementary. In clinical care, we recommend the consideration of IOP "modulation" rather than just IOP "reduction" when glaucoma patients are treated. Quality-based IOP control may be more effective than quantity-based IOP reduction to prevent or retard disease progression

General music teachers' practices of cooperative learning in two elementary music classrooms

The purpose of the study was to examine general music teachers’ practices of cooperative learning in two elementary music classrooms. Using the intrinsic case study method, I examined elementary general music teachers’ perspectives on cooperative learning, the utilization of cooperative learning in their general music classrooms, and the challenges the music educators faced in creating and implementing cooperative learning. I selected one general music classroom in two elementary schools in Boston, Massachusetts—totaling two general music teachers from different schools. I conducted eight class observations and three interviews for each participant during the fall 2016 semester. From separate and cross-case analyses, I found the following: (1) the two teachers’ instructions were linked to the characteristics of cooperative learning, (2) they believed that cooperative learning provided opportunities to improve students’ academic development in music and promote positive interpersonal relationships, and (3) both teachers used their own strategies for cooperative learning in order to maximize students’ learning. These findings provided evidence that cooperative learning engaged students in the process of learning music and, in addition, fostered positive interpersonal relationships. Moreover, this study suggested that music educators might undertake an effort to thoroughly understand students’ cognitive development when they wish utilize cooperative learning. Although this study was subject to a number of limitations due to its scope, the findings may contribute to the body of research on cooperative learning in elementary music education

Issues of Corrective Feedback in Second Language Acquisition

For decades now, questions about the role of corrective feedback in second language acquisition (SLA) have been hotly debated, spawning a great deal of theoretical and empirical research. Although the facilitative role of corrective feedback in SLA has received some empirical support, the claims regarding its impact on SLA have yet to be fully or decisively substantiated. In order to move this line of research forward, it is important to examine the issues arising in the SLA literature. To this end, this paper aims to review and discuss the literature throwing light on three major issues: (1) learners’ noticing of feedback, (2) potential mismatches between teachers’ intentions and learners’ interpretations, and (3) the role of different types of implicit corrective feedback

A Stylistic Analysis with Performance Suggestions of Robert Muczynski’s Selected Late Piano Works: Maverick Pieces, Opus 37, Masks, Opus 40, and Dream Cycle, Opus 44

Robert Muczynski (1929-2010) was a composer, pianist, and educator whose work is starting to garner more attention and interest from scholars, performers, and audiences. Muczynski’s musical output covers a variety of genres from works for solo instruments to orchestral works and film scores. He was especially devoted to writing for piano. This is well represented in his musical output. Among his forty-eight compositions with opus numbers, seventeen works are for solo piano. He also wrote a piano concerto (No.1, Op.7), and twelve chamber works featuring the piano. Although his music has increased in popularity, it is less discussed when compared to other American composers of the twentieth century. This study explores Muczynski’s later piano compositions, with a focus specifically on his last three piano compositions: Maverick Pieces, Op. 37, Masks, Op. 40, and Dream Cycle, Op. 44. This document does not explore Desperate Measures, Op. 48, which is already discussed in several other academic documents. Because of limited scholarship available, this document contributes to the existent literature pertaining to Muczynski’s later piano works in general and provides a stylistic analysis and discussion of each of these three works, as well as pianistic suggestions for the performer

An exploratory content analysis of comments and thumbnails of YouTube mukbang videos using computational methods

Mukbang continues to thrive on YouTube, originating as a trend but ultimately becoming ingrained in a cultural phenomenon. Nevertheless, the impact of Mukbang on individuals' eating patterns is a subject of debate. Mukbang videos can have negative consequences, such as weight gain and the development of eating disorders. Therefore, it is crucial to comprehend the viewers' perceptions of these videos. This study is exploratory research that utilizes computational methods to analyze comments and investigate the sentiment and emotion of the viewers. The mention of food cravings and YouTuber names is also being observed to find out if people focus on food or the YouTuber while they watch the video. Additionally, the visual attributes of the video thumbnails are examined to explore the visual characteristics of popular Mukbang videos. The results indicate that the dominant sentiment and emotion expressed by the people were 'positive' and 'happiness'. Additionally, the study reveals that the group that mentions craving or YouTubers showed a distinct sentiment from the group that does not. Visual analysis revealed that common characteristics observed in popular Mukbang videos include the use of warm colors and the inclusion of a person's face in their thumbnails.Advertisin

Measuring Willingness to Accept for GM Food by Characteristics

Korean consumers' willingness to accept (WTA) for GM food are studied in this paper. This study compares hypothetical and nonhypothetical responses to choice experiment questions. We test for hypothetical bias in a choice experiment involving GM rice with differing characteristic attributes and multinomial logit model is applied to predict the estimated results. In general, hypothetical responses predicted higher probabilities of purchasing GM rice than nonhypothetical responses. Thus, hypothetical choices overestimate willingness to accept for GM rice. The results of this paper could contributes to government's GM food policies and subsequent studies, also improving economic welfare of farmers and consumers.GM Food, Willingness to Accept, Choice experiment, Hypothetical bias, Food Consumption/Nutrition/Food Safety,

Optimal design of quadratic electromagnetic exciter

The vibration acceleration of collecting plates, which is the core indicator of rapping performance in an electrostatic precipitator’s vibration rapping process, is determined by magnetic force of a quadratic electromagnetic exciter. The larger exciter provides the larger magnetic force, but the installation space for the exciter is limited. Accordingly, this paper presents the optimal design of quadratic electromagnetic exciter to maximize the magnetic force with constraint that the size of exciter is constant. A design optimization problem was formulated in order to find the quadratic electromagnetic exciter shape parameters that maximized the magnetic force. The magnetic force of the quadratic electromagnetic exciter was evaluated using the commercial electromagnetic analysis software “MAXWELL”. For efficient design, we employed metamodel-based design optimization using design of experiments (DOE), metamodels, and an optimization algorithm equipped in PIAnO (Process Integration, Automation and Optimization), a commercial PIDO (Process Integration and Design Optimization) tool. Using the proposed design approach, the optimal magnetic force was increased by 1.68 % compared to the initial one. This result demonstrates the effectiveness of the established analysis and design procedure for the quadratic electromagnetic exciter
