Background: Childhood obesity is dramatically on the rise throughout the world. Screening and prevention are ideal, but treatment becomes necessary when a child’s body mass index (BMI) is 95% and greater. Obesity related illness leads to premature death. Local Problem: The current practice at the clinical site for this project is to send the child for lab work and follow up in three months after implementing lifestyle changes, including diet and exercise. Follow-up visits, often canceled or forgotten, contribute to a lack of evaluation and not being seen until the next annual well visit. Methods: The measurable outcomes are the pre and post BMI measurements. A paired t-test was used for data analysis. Compliance with the program was determined by the dietary logs. Interventions: The childhood obesity project was a self-management project, incorporating weekly telemedicine visits with a pediatric provider. The child’s progress was documented via the dietary log and addressed weekly with the provider. Results: There were five participants at the completion of the program. The BMI levels of the pre-intervention period (M = 21.06, SD = 2.86563) and the post-intervention period (M = 20.9, SD = 3.13688) indicated that there was not a significant change in participant BMI as a result of the eight-week intervention period, t(4) = 0.436, p = 0.685. Conclusions: This program is feasible and can be utilized by other families and providers in futures studies. The availability of telemedicine is convenient for busy families. Further studies are recommended with a larger sample size and a longer implementation period to recognize improved change.
This paper deals with the collision of sphere shape grenades with sand media.The central issue of the article is the establishing of an empirical velocity equation of the grenade while impacting on sand that is used to solve motion equations of the mechanical mechanism inside the impact grenade fuze.The paper focuses on impact velocities that are lower than 5 m s^(-1).An experiment was conducted to study the velocity of the grenade while impacting on dry sand.A high-speed camera video was used to capture the grenade positions.The grenade velocity in the impact process was generated from these video data.Some types of fitting curves are used to regress the velocity equation of the grenade while interacting with the sand media and the best-fitting model is chosen.The result shows the regression curve has a high correlation with the experiment data for grenade velocities below 5 m s^(-1).The received regression equation is useful for analyzing the working ability of the inertial mechanism inside the impact grenade or analyzing and choosing the appropriate parameters of each part in the inertial mechanism to meet the required characteristics of the mechanism.

目前海上钻井作业日趋复杂,在水平井中需要在钻进过程中进行导向,以确保其始终保持在开发层中,尽管随钻测井(Logging while Drilling,LwD)技术已被广泛应用,但有时基于薄开采区上下厚度的限制,这种地质导向只能通过特定的设备(旋转导向)来实现,当井打到储层与非储层间交界处时,LwD可以检测到,由于有了旋转导向便可立即调整,非导向设备无法用于矫正井眼轨迹,因此需要使用LwD加旋转导向联合作业。基于此,本文就针对上述问题展开论述,以供参考。
