The Family-School Relationships in Europe: A Research Review
Paola Dusi
CEPS Journal : Center for Educational Policy Studies Journal , 2012,
Abstract: The literature on research carried out in the field and parents’ and teachers’ declarations all point in the same direction: good collaboration between home and school is useful to the child-student for his education and learning. Despite this, parent-teacher relationships in Europe (and elsewhere), from Spain to Sweden, from Ireland to Greece, and from Italy to the Czech Republic, represent an unresolved issue. This is a complex relationship that calls into play various social spheres: macro (social), intermediary (institutional) and micro (relational); in fact, there are as many diverse realities as there are schools. In Europe, the relationship between individual behaviours (parents vs. teachers), social orientations (neoliberalism) and institutional frameworks (school markets)appears significant: scarce parental participation, lack of adequate forms of home-school communications, and the need to make investments in parent and teacher training. Nevertheless, family and school are called on to create a dialogue in order to contribute to the processes of training new generations. They both need each other in order to carry out that task in the best way. This paper presents and discusses the results of a theoretical analysis conducted on the basis of the international literature concerning research on the school-family relationship, with particular attention on the situation of different European countries, and concludes with suggestions for some practical improvements.

Tatsuya Kai
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.412235
Abstract:

This paper develops an integrating algorithm for fully rheonomous affine constraints and gives theoretical analysis of the algorithm for the completely integrable case. First, some preliminaries on the fully rheonomous affine constraints are shown. Next, an integrating algorithm that calculates independent first integrals is derived. In addition, the existence of an inverse function utilized in the algorithm is investigated. Then, an example is shown in order to evaluate the effectiveness of the proposed method. By using the proposed integrating algorithm, we can easily calculate independent first integrals for given constraints, and hence it can be utilized for various research fields.

On Integrability of Fully Rheonomous Affine Constraints  [PDF]
Tatsuya Kai
International Journal of Modern Nonlinear Theory and Application (IJMNTA) , 2013, DOI: 10.4236/ijmnta.2013.22016
Abstract:

This paper presents a complete integrability condition for fully rheonomous affine constraints in terms of the rheonomous bracket. We first define fully rheonomous affine constraints and develop geometric representation for them. Next, the rheonomous bracket is explained and some properties of it are derived. We then investigate a necessary and sufficient condition on complete integrability for the fully rheonomous affine constraints based on the rheonomous bracket as an extension of Frobenius’ theorem. The effectiveness and the availability of the new results are also evaluated via an example.

Partial Integrability Conditions and an Integrating Algorithm for Fully Rheonomous Affine Constraints  [PDF]
Tatsuya Kai
Circuits and Systems (CS) , 2014, DOI: 10.4236/cs.2014.56015
Abstract:

In this paper, integrability conditions and an integrating algorithm of fully rheonomous affine constraints (FRACs) for the partially integrable case are studied. First, some preliminaries on the FRACs are illustrated. Next, necessary and sufficient conditions on the partially integrable case for the FRACs are derived. Then, an integrating algorithm to calculate independent first integrals of the FRACs for the partially integrable case is derived. Moreover, the existence of an inverse function utilized in the algorithm is proven. After that, an example is presented for evaluation of the effectiveness of the proposed method. As a result, it turns out that the proposed integrating algorithm can easily calculate independent first integrals for given partially integrable FRACs, and thus this new algorithm is expected to be applied to various research fields.

Tatsuya Kai
International Journal of Modern Nonlinear Theory and Application (IJMNTA) , 2015, DOI: 10.4236/ijmnta.2015.43013
Abstract: This paper considers an obstacle avoidance control problem for the compass-type biped robot, especially circular obstacles are dealt with. First, a sufficient condition such that the swing leg does not collide the circular obstacle is derived. Next, an optimal control problem for the discrete compass-type robot is formulated and a solving method of the problem by the sequential quadratic programming is presented in order to calculate a discrete control input. Then, a transformation method that converts a discrete control input into a continuous zero-order hold input via discrete Lagrange-d’ Alembert principle is explained. From the results of numerical simulations, it turns out that obstacle avoidance control for the continuous compass-type robot can be achieved by the proposed method.
A New Efficient Obstacle Avoidance Control Method for Cars Based on Big Data and Just-in-Time Modeling  [PDF]
Tatsuya Kai
Journal of Computer and Communications (JCC) , 2018, DOI: 10.4236/jcc.2018.611002
Abstract: This paper provides a new obstacle avoidance control method for cars based on big data and just-in-time modeling. Just-in-time modeling is a new kind of data-driven control technique in the age of big data and is used in various real systems. The main property of the proposed method is that a gain and a control time which are parameters in the control input to avoid an encountered obstacle are computed from a database which includes a lot of driving data in various situations. Especially, the important advantage of the method is small computation time, and hence it realizes real-time obstacle avoidance control for cars. From some numerical simulations, it is showed that the new control method can make the car avoid various obstacles efficiently in comparison with the previous method.

Michiyo Ando, Tatsuya Morita
Health (Health) , 2010, DOI: 10.4236/health.2010.24051
Abstract: GOALS: The aims of this study were to evaluate the treatment efficacy of the structured life review interviews and the Short-Term Life Review on the spiritual well-being of terminally ill cancer patients, in order to improve patients’ quality of life. SUBJECTS and METHODS: Participants were patients in palliative care units in Japan. In the study 1, the structured life review interviews were conducted with 12 patients. They completed the QOL scale of the SELT-M (Skalen zur Erfassung von Lebens qualitat bei Tumor- kranken–Modified Version) questionnaire before and after the interviews. In the study 2, the Short-Term Life Review was conducted with 30 patients. They reviewed their lives in the first session and they confirmed the contents in the album based on the life review in the second session. Duration of the treatment was one week. Measurement instruments included Func- tional Assessment Chronic Illness Therapy- Spiritual (FACIT-Sp). RESULTS: After the structured life review, the mean overall QOL score and Spirituality subscale score of the SELT-M significantly increased, from 2.57 ± 0.61 to 3.58 ± 1.0 (p=0.013) and 2.57 ± 0.61 to 3.14 ± 2.25 (P=0.023), respectively. After the Short-Term Life Review, the mean FACIT-Sp scores significantly increased from 16 ± 8.2 to 24 ± 7.1. CONCLUSION: Both the structured life review and the Short-Term Life Review may be effective in improving the spiritual well-being of terminally ill cancer patients, being higher feasibility for the Short-Term Life Review. We need to use these therapies understanding characteristics of each therapy.

Journal of Biomaterials and Nanobiotechnology (JBNB) , 2012, DOI: 10.4236/jbnb.2012.31007
Abstract: Development of new way and system for multidrug delivery has recently attracted much attention and became one of major issue in drug delivery research. Although this research field is still immature compared to the single drug delivery system, intensive efforts have recently been devoted by researchers in order to realize more efficient, functional, and safe combination therapy using multiple drugs or agents. In this review article, we outline several targets in terms of application for biochemical modulation together with various concrete attempts of simultaneous and sequential delivery of multiple drugs or agents with single formulation. Finally, we will also summarize the possible contribution of biomaterial sciences and nanobiotechnology for improvement of future multidrug delivery system.
Homeostasis Lighting Control System Using a Sensor Agent Robot  [PDF]
Tatsuya Akiba, Akira Mita
Intelligent Control and Automation (ICA) , 2013, DOI: 10.4236/ica.2013.42019
Abstract: In this study, “homeostasis”, the function by which living things keep their constancy, was emulated as a lighting control for a building space. The algorithm we developed mimics the mechanisms of the endocrine and immune systems. The endocrine system transmits information entirely, whereas the immune system transmits information with a concentration gradient. A lighting control system using the proposed algorithm was evaluated in a simulation and experiment using a sensor agent robot. In this algorithm, a robot recognizes a person’s behavior and uses it to decide his or her preference as to the illuminance. The results indicate that the algorithm can be used to realize a comfortable lighting control in several situations.
