연구논문 : 자원봉사활동을 통한 학습효과 증진

( Cecilia Isidro Anido ) 극동대학교 사회복지연구소 2013 글로벌사회복지연구 Vol.3 No.1

고등교육기관은 전통적으로 새로운 지식을 발견하고 연구하는 학문적인 기능을 수행하는 것으로 알려져 왔다. 그러나, 많은 대학들은 교직원과 학생들로 하여금 양질의 학습 및 연수활동에 참여시키기 위해 지역사회 서비스와 자원봉사 활동의 중요성을 인식하고 있다. 자원봉사는 급격하게 변화하는 고등교육 환경에서 실질적이고 경험적인 학습을 제공하고 있다. 본 논문은 아시아 협력 대학에서 수행한 극동대학교 자원봉사 활동이 중요한 학습경험을 제공하고 있음을 보여주고 있다. 자원봉사 경험을 통해 학생들은 세계가 직면한 문제를 인식하고 이해하게 되었으며 세계적 차원의 관점을 얻은바 있고, 미래의 자원봉사활동에 보다 적극적으로 참여하게 되는 기회를 마련하였다. Higher Education Institutions are traditionally known to carry out the scholarly function of research and the discovery of new knowledge. However, many universities recognize the importance of community service and volunteer work to engage the faculty, staff and students in high quality learning and teaching practices. Volunteerism provides practical, experiential learning in the rapidly changing higher education environment. This paper presents the activities undertaken by Far East University volunteers in coordination with partner universities in Asia that provided meaningful learning experiences. Reflections of volunteers showed that they gained a better understanding and awareness of the problems facing the world, gained a more informed world-view, and became open to new ideas and the desire to participate in future volunteer activities.

Modelling the Hydrogen-Bonding Interactions in a Copolymer/Biodegradable Homopolymer Blend through Excess Functions

Rosa Garc’a-Lopera,Isidro S. Monzó,Agust’n Campos,Concepci—n Abad 한국고분자학회 2008 Macromolecular Research Vol.16 No.5

A recent theoretical approach based on the coupling of both the Flory-Huggins (FH) and the Association Equilibria thermodynamic (AET) theories was modified and adapted to study the miscibility properties of a multi-component system formed by two polymers (a proton-donor and a proton-acceptor) and a proton-acceptor solvent, named copolymer(A)/solvent(B)/polymer(C). Compatibility between polymers was mainly attained by hydrogen-bonding between the hydroxyl group on the phenol unit of the poly(styrene-co-vinyl phenol) (PSVPh) and the carbonyl group of the biodegradable and environmentally friendly poly(3-hydroxybutyrate) (PHB). However, the self-association of PSVPh and specific interactions between the PSVPh and the H-acceptor group (an ether oxygen atom) of the epichlorohydrin (ECH) solvent were also established in a lower extension, which competed with the polymer-polymer association. All the binary specific interactions and their dependence with the system composition as well as with the copolymer content were evaluated and quantified by means of two excess functions of the Gibbs free energy, ΔgAB and ΔgAC. Experimental results from fluorescence spectroscopy were consistent with the theoretical simulations derived with the model, which could also be applied and extended to predict the miscibility in solution of any polymer blend with specific interactions.

Theoretical axial wall angulation for rotational resistance form in an experimental-fixed partial denture

John Francis Bowley,Elizabeth Krall Kaye,Raul Isidro Garcia 대한치과보철학회 2017 The Journal of Advanced Prosthodontics Vol.9 No.4

PURPOSE. The aim of this study was to determine the influence of long base lengths of a fixed partial denture (FPD) to rotational resistance with variation of vertical wall angulation. MATERIALS AND METHODS. Trigonometric calculations were done to determine the maximum wall angle needed to resist rotational displacement of an experimental-FPD model in 2-dimensional plane. The maximum wall angle calculation determines the greatest taper that resists rotation. Two different axes of rotation were used to test this model with five vertical abutment heights of 3-, 3.5-, 4-, 4.5-, and 5-mm. The two rotational axes were located on the mesial-side of the anterior abutment and the distal-side of the posterior abutment. Rotation of the FPD around the anterior axis was counter-clockwise, Posterior-Anterior (P-A) and clockwise, Anterior-Posterior (A-P) around the distal axis in the sagittal plane. RESULTS. Low levels of vertical wall taper, ≤ 10-degrees, were needed to resist rotational displacement in all wall height categories; 2-to-6-degrees is generally considered ideal, with 7-to-10-degrees as favorable to the long axis of the abutment. Rotation around both axes demonstrated that two axial walls of the FPD resisted rotational displacement in each direction. In addition, uneven abutment height combinations required the lowest wall angulations to achieve resistance in this study. CONCLUSION. The vertical height and angulation of FPD abutments, two rotational axes, and the long base lengths all play a role in FPD resistance form.

Novel Sources of Resistance to Phytophthora capsici on Pepper (Capsicum sp.) Landraces from Mexico

Phytophthora capsici Leonian is a major pathogen of pepper worldwide and few resistance sources to this pathogen have been identified so far. The goals of this study were to identify new sources of resistance against P. capsici in Capsicum landraces and analyze the relationship between the resistance indicator of plant symptoms and some plant phenotype parameters of plant height, stem width, leaf length and leaf width. Thirtytwo landraces of pepper were collected from fourteen states in Mexico. From each population, 36 plants were inoculated with 10,000 zoospores of P. capsici under controlled conditions. This experiment was repeated twice. Out of the 32 landraces, six showed high level of resistance, four showed intermediate resistance and five showed low level of resistance when compared with the susceptible control ‘Bravo’ and the resistant control ‘CM334’, indicating that these landraces are promising novel sources of resistance to P. capsici. There was no correlation between the symptoms and plant phenotype parameters. However, these parameters were not affected in the group classified as highly resistant, indicating that P. capsici does not affect the growing of these resistant pepper landraces. The other resistant groups were significantly affected in a differently manner regarding their phenotype, indicating that this pathogen reduce their growth in different ways. This study reports novel resistance sources with great potential that could be used in breeding programs to develop new pepper cultivars with durable resistance to P. capsici.

Design of intelligent control strategies using a magnetorheological damper for span structure

Hernandez, Angela,Marichal, Graciliano N.,Poncela, Alfonso V.,Padron, Isidro Techno-Press 2015 Smart Structures and Systems, An International Jou Vol.15 No.4

This paper focuses on the design of an intelligent control system. The used techniques are based on Neuro Fuzzy approaches applied to a magnetorheological damper in order to reduce the vibrations over footbridges; it has been applied to the Science Museum Footbridge of Valladolid, particularly. A model of the footbridge and of the damper has been built using different simulation tools, and a successful comparison with the real footbridge and the real damper has been carried out. This simulated model has allowed the reproduction of the behaviour of the footbridge and damper when a pedestrian walks across the footbridge. Once it is determined that the simulation results are similar to real data, the control system is introduced into the model. In this sense, different strategies based on Neuro Fuzzy systems have been studied. In fact, an ANFIS (Artificial Neuro Fuzzy Inference System) method has also been used, in addition to an alternative Neuro Fuzzy approach. Several trials have been carried out, using both techniques, obtaining satisfactory results after using these techniques.
