Multi-Loop Edge Wise Arch Wire Technique (MEAW) – A Review

Anterior open bite treatment is considered to be a complex treatment in the field of orthodontics. Orthognathic surgery is often the treatment of choice for these types of malocclusions and prognosis of the results are still questionable. With the introduction of Multiloop edgewise archwire therapy, treatment of open bite has started showing efficient results. Moreover, MEAW is versatile as it is capable of correcting various malocclusions as well such as Class II, Class III, deep overbite, and malocclusions with marked midline deviations. Since the advent of the MEAW, its treatment modality has been used worldwide and numerous reports of successful results have been published. Some orthodontists have described the MEAW technique as “magical” or “unbelievable,” but it certainly is not. The diagnosis and treatment plan must be correct and construction of the MEAW must be precise to deliver the necessary forces to move the teeth to an optimal, stable relationship.Hence this article aims to review the multiloop edge wise arch wire technique in detail along with its biomechanics.

Evaluation of Child Friendly School in Building Student Character: A Literature Review

The character crisis is an issue of many countries. For many children, the school is an uncaring environment, that can cause a negative impact in mental health, so we can see the output of school residents is not in a good character. In fact, schools have an important role in the psychosocial development of children. Seeing this fact, UNICEF developed a child-friendly school program to solve the problem. Its also necessary to evaluate the child friendly school programme, then it will be discussed about CIPP model too. The results of the review found that child-friendly schools can be optimal if principals, teachers and education staff, and school committees collaborate well in carrying out their roles in realizing the six principal components of child-friendly schools. Research on this topic is limited and this article is a literature review, so it is necessary to conduct further research using interview and questionnaire methods related to the role of child-friendly schools in building student character.

Rainwater Infiltration Box to Prevent Flood Disaster

Flood disaster is a natural disaster that ranks the third cause of economic loss worldwide. As a tropical country that has a rainy season, every year some parts of Indonesia are prone for being affected by floods. The causative factors include high rainfall and poor surface water management, making rainwater directly converted into surface water (run-off). Efforts to reduce run-off water include making biopores infiltration wells from paralon pipe material with a diameter of 10 centimeters, but because of the small volume, the biopores cannot functioned properly, so it is necessary to build infiltration wells with a larger capacity. The purpose of this research is to make a model of infiltration wells that have a larger volume than stainless steel.
This study used a pre-experimental design and is a development research of biopores infiltration wells. The stages in this research include design validation and absorption function testing.

Determination of the Maxx Prospect Zone Petrophical Parameters in MA06 Well MA Field with Log Data Analysis

The well logging method is one of the methods used in petrophysical analysis to assess the formations used in obtaining information and shadows related to a reservoir. In addition, in an effort to determine success in the oil and gas field, this method is also included for calculating petrophysical values such as permeability, water saturation, and porosity. Then this value will be used in finding the initial oil reserves (OOIP) and initial gas reserves (GIIP) in the MA field. This will be very helpful in developing further oil and gas fields because materials are available as a basis for reference. This study analyzes the MA field precisely at the MA-06 Well by utilizing the qualitative and quantitative petrophysical analysis method by only referring to log data because there is no availability of core data. To find out the depth of the prospect zone and what fluid is in the formation, the authors analyze it in a qualitative way, namely by determining the permeable zone, then looking at the resistivity value, then determining the type of fluid on track 3. While in obtaining petrophysical values such as shale volume, porosity, water saturation and rock permeability the authors chose to use quantitative methods to analyze them. So that the results of the analysis carried out, it was found that the MAXX well has a net sand thickness of 36 feet and a net pay of 36 feet with an average value of shale volume, porosity, water saturation and permeability in that zone respectively 34.8%. , 18.03%, 35.3%, and 38.31 mD.

Comparison of Mobility Behavior of Children from a Physical Education Kindergarten with Children from a Regular Kindergarten

Mobility in the sense of the International Classification of Functioning, Disability and Health ICF-CY is an important prerequisite for participation in everyday life. The present study aims to show to what extent a movement promotion program in kindergarten has an effect on mobility behavior. Methods: The sample consists of 46 boys and 34 girls (age 4.51 ± .98 years) from one regular and one physical education kindergarten. The MobiScreen 4-6 was performed. Group differences were examined using a t-test, and multiple linear regression analysis was used to examine the effects of the predictors kindergarten affiliation, age, sex, born premature, sports club membership, and number of sports hours in the club. Results: Total time shows a strong multiple coefficient of R = .75 with an explained variance of R² = .57; total score also shows strong values of R = .59 and R² = .35. Age and sports club membership are the strongest predictors for both variables. Conclusions: Since raw values are analyzed for total time and score, the high influence of age is obvious. The effect of sports club membership indicates that the children may be better supported in their free time than in the concept of physical education kindergarten. Therefore, the concept of the physical education kindergarten should be reviewed and standardized.
