Pain-Relieving Effect of Music on Preschoolers during Immunization

Immunization is a medical procedure many children frequently undergo. As it involves pain, it is important to develop effective pain relief methods that are applicable from infancy. And the methods to reduce immunization-related pain in children are usually classified into pharmacological and non-pharmacological approaches. The latter include: musical interventions, distraction using videos, breathing techniques, sucrose administration, and so on. In this study, the authors aimed to clarify the pain-relieving effect of music from speakers on preschoolers during immunization.

A randomized controlled trial using sex-based stratified randomization was conducted at a Japanese pediatric clinic between October and December 2016, involving 48 preschoolers aged 5 - 6. Among these, 25 listened to music (“Twinkle Twinkle Little Star” played by a music box) from speakers before, during, and after influenza immunization (Music group), while the other 23 were not treated with musical intervention (Control group), with the following outcomes: primary: the Face Scale score; and secondary: the heart rate (HR) and oxygen saturation (SpO2) and salivary alpha amylase (sAA) levels. The demographic variables, confounders, Face Scale score, HR, and sAA level were compared between the Music and Control groups. The categorical variables were examined using Fisher’s exact test, while the continuous variables were analyzed using the Wilcoxon rank sum test or unpaired t-test based on the results of the Shapiro-Wilk test.

The results showed that there were no significant differences between the 2 groups in the age or sex. Among the confounders, only the rate of having a history of NICU admission was significantly higher in the Control (4; 17.39%) compared with Music (0; 0%) group (P = 0.0455). The Face Scale score and HR of the Control group immediately after influenza immunization were significantly higher than their baseline values (P < 0.0001, P < 0.05). There were no significant differences between the Music and Control groups in the Face Scale score, HR, or SpO2 level immediately after influenza immunization or in the sAA level 10 minutes after it.

In conclusion, influenza immunization was painful for preschoolers. When based on the Face Scale score, HR, SpO2 and sAA levels as indices to measure immunization-related pain, music did not show pain-relieving effects. Therefore, it may be necessary to further examine the effect of music to reduce immunization-related distress in preschoolers.

Incorporation of High-Altitude Balloon Experiment in High School Science Classrooms

High-altitude balloon is a balloon, filled usually with helium or hydrogen that ascends into an area called “near space” or stratosphere. The most common type of high-altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. The mission of the High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate enabling technologies, and resolve critical acquisition, tracking, and pointing (ATP) and fire control issues in support of future space-based precision pointing experiments. The use of high-altitude balloons offers a relatively low-cost, low-vibration test platform, a recoverable and reusable payload, worldwide launch capability, and a 'near- space' emulation of the future space systems operational scenarios. More recently, several university...

Location Optimization of a Coal Power Plant to Balance Costs against Plant’s Emission Exposure

Fuel and its delivery cost comprise the biggest expense in coal power plant operations. Delivery of electricity from generation to consumers requires investment in power lines and transmission grids. Placing a coal power plant or multiple power plants near dense population centers can lower transmission costs. If a coalmine is nearby, transportation costs can also be reduced. However, emissions from coal plants play a key role in worsening health crises in many countries. And coal upon combustion produces CO 2 , SO 2 , NO x , CO, Metallic and Particle Matter (PM10 & PM2.5). The presence of these chemical compounds in the atmosphere in close vicinity to humans, livestock, and agriculture carries detrimental health consequences. The goal of the research was to develop a methodology to minimize the public’s exposure to harmful emissions from coal power plants while maintaining minimal operational costs related to electric distribution losses and coal logistics. The objective was...

Effects of Karate Training on Basic Motor Abilities of Primary School Children

“You never attack first in karate” might be the best conclusion of karate, which is a martial art practiced typically without weapons. It’s reported that karate has a long history for several hundred years, but the modern karate was spread to the whole Japan from Okinawa in the early part of 20th century. Now it has become one of the most widely practiced martial art forms in the world. Usually, it’s divided into Kihon, Kata and Kumite. As for the beginners, Kihon is more suitable for them because it involves basic techniques. Due to karate consists of dynamic offensive and defensive techniques using all parts of the body to their maximum advantage, the best understanding of true karate practice is the perfection of oneself through the perfection of the art. It not only develops coordination, quickens reflexes, and builds stamina, but also develops composure, a clearer thought process, deeper insight into one’s mental capabilities, and more self-confidence. So many researchers stu...
