This paper tries to highlight some biomechanical characteristics of the transfer in the rotational movements on uneven bars in women’s artistic gymnastics. This scientific approach led to a study conducted during the Masters National Championships from 16th to 18th of October 2012, in ”Nadia Comaneci” Polyvalent Hall of Onești. The study involved 7 gymnasts belonging to junior training team of Deva, aged 12 to 15. The following methods have been used in this research: method of bibliographic study, method of pedagogical observation, method of biomechanical video analysis using Kinovea and Physics Toolkit programs, experiment method, statistical method (KyPlot) and the method of graphical representation (Excel). The analysis of difficulty values of the technical elements on uneven bars as per the Code of Points emphasizes the dynamics of the vertical and horizontal transfer, depending on the category / type of the movement and the difficulty group. The results of the study highlights how the transfer is made throughout the routines on uneven bars in terms of kinematics and dynamic characteristics of the key elements of sports technique during the rotational movements. The efficient use of the postural orientation method based on the biomechanical analysis of the rotational movements on uneven bars showed the kinematic and dynamic characteristics of the key elements of sports technique according to the performances achieved in competition.

The purpose of this research is to identify physical deficiencies in fighting sports athletes. It was conducted at the Children’s Palace (judo), the School Sports Club (wrestling) and the ‘Am Duong’ Sports Club (martial arts) of Bacau, Romania, and it studied three groups of subjects, each comprising seven male athletes, aged 13–16. The research methods used in this research were the documentation method, the observation method, the inquiry, the assessment, the experimental method, the analysis of the results and the graphical representation. The assessment method used was somatoscopy and the objective methods were the instrumental somatoscopic of the body alignment and somatometry. The results show a homogeneous distribution of the results for the three groups, with more than 42% of the athletes having a lumbar and cervical lordosis. In the other two groups, the distribution is homogeneous, 57.1% recording a correct posture, and 42.9% a frontally inclined head position. Keywords: Incidence, physical deficiencies, fighting sports, athletes

A new approach to the geometrical representation of manipulator dynamics is presented. The inertia ellipsoid, which is used to represent dynamic characteristics of a single rigid body, is extended to a general ellipsoid for a series of rigid bodies in order to represent the manipulator dynamics. The geometrical configuration of the generalized inertia ellipsoid (GIE) represents the characteristics of the manipulator as a whole. One can understand the complicated inertial effect and nonlinearity of multi-degree-of-freedom motion by simply investigating the GIE configuration. In the latter half of the paper, this method is applied to aid the design of a mechanical arm, in which dimensions of an arm structure and its mass distribution are optimized through the evaluation and graphical representation of the arm dynamics.

This research aimed to examine the implementation of a scientific approach on biology learning of grade X state senior high school in Wonogiri viewed from teacher's employment status. It is descriptive research using the observation method. The subject involved Biology teachers of grade X and the students of grade X as many as 1 class from each school. Employing a convenience sampling technique, the researchers selected a sample of 6 biology teachers from grade X. The independent variable was the biology teacher's employment status, and the dependent variable was the scientific implementation approach on biology learning. The instrument used in this research was an observation sheet. The acquired data then analyzed descriptively. The research results have indicated that biology teachers' employment status who is a civil servant or non-civil servant has implemented the scientific approach well. The students' involvement and activity were positive during the learning process.
