The purpose of this study is to explore the effects of mobilization of C0-C1 and C7-T1 applied to asymptomatic individuals with reduced upper cervical rotation during the FRT. Design: parallel randomized controlled trial. 48 subjects(38.52 years±15.13) with C1-C2 rotation hypomobility in TFR joined the study and were randomized into three groups(C0, C7, control group). FRT in both directions was measured before and after the intervention. C0 intervention consisted of a dorsal translatoric mobilization of C0-C1 in the cervical neutral position. C7 intervention consisted of a ventral cranial translatoric mobilization of C7- T1 in neutral position and the control group maintained a supine position. C0 group experienced a FRT ROM to the restricted side increase of 17.64。(SD=4.55), that was significantly greater (P<0.001) than 5.95。 (SD=4.81) of the C7 group and 2.45。(SD=5.05) of the control group. The results showed that a dorsal translatoric mobilization of C0-C1 in neutral position restored the physiological FRT mobility in subjects with C1-C2 hypomobility and experienced statistical significant improvement in FRT as compared to a C7-T1 translatoric mobilization and a control group.

César Higuera,Jesús Sandoval,Luis N. Coria,Eusebio Bugarin 대한기계학회 2022 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.36 No.1

This paper presents an autonomous unmanned underwater vehicle (AUUV) that can be used as a support tool for research tasks in underwater exploration, and as a platform to test different control, communication, or vision algorithms. The vehicle operates without an external power cable and with an original modular program where a web page is enabled as a graphical user interface for wireless communication with the vehicle when it is not submerged. The modular design of the program, based on open-source libraries, allows updating or modifying the configuration of each of its main modules: control, inertial unit, and vision. Experimental results are shown to validate the performance of the proposed vehicle, implementing a non-linear control that includes a PID for the trajectory tracking of its pose (position and orientation).

The DNA of a Dreamer

( César Castellanos Dominguez ) 한세대학교 영산신학연구소 2013 영산신학저널 Vol.28 No.-

What is the secret to building a great ministry? How can a person enter into the realm of the Spirit and build a truly significant work for God? In this article the author sets out to answer these and related questions by looking at the life and ministry of his mentor, Dr. Yonggi Cho of Korea. From the outset the author gives us the simple, clear answer—dream! We quickly discover the principle that dreams are the language of the Spirit. The article looks at the whole dimension of entering into the realm of the Spirit by faith and prayer, believing God for great and specific things. Dr. Cho’s progress in life and ministry is described including his many impressive achievements as well as the considerable challenges and inevitable low points he has faced. The author also gives us key insights into the nature and characteristics of a dreamer including the way we speak and press on, through adverse circumstances, in order to see the reward for our faith. And here is the final key—any one of us can be someone who moves in the realm of the supernatural, who can see God do amazing things if, like Dr. Cho, we engage with the Holy Spirit and dare to dream.

César Alejandro Alcaraz Acosta 한국외국어대학교 중남미연구소 2022 중남미연구 Vol.41 No.4

Educational policies are actions undertaken by a government for the conservation and improvement of teaching practices and outcomes. At times, these policies act in forms of production and supply that determine the course of education of a country. Mexico is a country that every six-years, it evaluates, modifies, and updates its educational policies to try to provide quality education. With the presidential succession of Andrés Manuel López Obrador (AMLO) and the implementation of the Fourth Transformation (T4), which can be understood as a transition from one administration to a new one that gradually applies and makes changes in all educational areas. In this context, the New Mexican School, established in 2018, is subject to an educational policy created to counter the 2013 Educational Reform of former President Enrique Peña Nieto. This research is a comparative analysis between both presidential proposals in how each aim to achieve excellence in education and second, a qualitative study to verify the effectiveness and efficiency of the reforms. The purpose of the research is to reveal how much basic education teachers know, the scope of both educational proposals and the impact on schools. Las políticas educativas son las acciones emprendidas por un gobierno para la conservación y mejora de las prácticas de enseñanza, además son la forma de producción y oferta con las que se determina la educación de un país. México es un país que cada sexenio modifica, evoluciona y actualiza sus políticas educativas para intentar brindar una educación de calidad. Con la sucesión presidencial de Andrés Manuel López Obrador (AMLO) y la implementación de la Cuarta Transformación (4T), que se puede entender como una transición de un régimen a otro nuevo, aplicando cambios gradualmente en cada una de sus áreas. En este contexto surge la Nueva Escuela Mexicana, establecida en 2018, siendo una política educativa creada para contrarrestar la Reforma Educativa de 2013 del expresidente Enrique Peña Nieto. La presente investigación es primero un análisis comparativo entre ambas propuestas presidenciales para alcanzar la tan anhelada educación con excelencia y segundo un estudio cualitativo para comprobar la eficacia y eficiencia de las reformas. La investigación tiene como finalidad dar a conocer qué tanto conocen los docentes de la educación básica, del alcance de ambas propuestas educativas y del impacto en las escuelas.

Port-city relationships in Europe and Asia

César Ducruet 인하대학교 정석물류통상연구원 2006 JOURNAL OF INTERNATIONAL LOGISTICS AND TRADE Vol.4 No.2

This paper investigates the nature of port-city relationships in two major port regions of the world, Europe and Asia. Although this issue is well analyzed through either isolated case studies or general models, it proposes a complementary approach based on urban and port indicators decline of port-urban dependence, stemming from changes in global transportation and urban development. However, European and Asian port cities are not identically confronted to the same challenges, notably in terms of their hinterlands. A factor analysis highlights a regional differentiation of port-city relationships according to their insertion in both urban and port systems, with a core-periphery dualism in Europe and a port-city hierarchy in Asia. Thus, the distance to inland markets for European ports and the size of coastal markets for Asian ports are evaluate which European and Asian port cities are comparable beyond their cargo volumes, by putting together micro (local environments) and macro (regional patterns) factors.

Cities and Transport Networks in Shipping and Logistics Research

César DUCRUET,Igor LUGO 한국해운물류학회 2013 The Asian journal of shipping and Logistics Vol.29 No.2

While shipping and logistics studies often describe the flows and networks on the level of firms and terminals rather than cities, urban studies pay limited attention to transport infrastructure and material flows. The renewal of network analysis based on complex systems will be discussed in this paper as a potential bridge between those two approaches. It particularly focuses on how transport and urban elements can be mutually integrated. The main conclusion points at the efforts to better untangle network/carrier and urban/territorial effects in the design and operation of shipping and logistics systems.

Towards an Integrated Management System (IMS), harmonizing the ISO/IEC 27001 and ISO/IEC 20000-2 Standards

César Pardo,Francisco J. Pino,Félix Garcia 보안공학연구지원센터 2016 International Journal of Software Engineering and Vol.10 No.9

In recent times, and in order to maintain an integrated, efficient and homogeneous policy, Integrated Management Systems (IMS) have emerged as an opportunity to improve processes related to Information Technology (IT) in organizations in a way that is modular, consistent and orderly. The ISO 27001 and ISO 20000 standards provide good practices for creating and/or strengthening management infrastructure whose purpose is information security and IT services. In an attempt to provide information on how these standards are related, as well as to facilitate their integration under a single IMS, this article presents the harmonization strategy and results of the harmonization of standards ISO 27001 and ISO 20000 in an organization. The work thereby supports organizations which are interested in knowing how to carry out the harmonization of these models. It also provides a detailed analysis of their similarities and differences, showing an example of how to carry out the integration of related practices between ISO 27001 and ISO 20000-2. In addition, some benefits achieved by the organization are presented.

Coffee (Coffea arabica L.) is threatened by biotic and abiotic stresses. Nevertheless, the breeding of Arabica coffee is restricted due to its low genetic diversity. Crop improvement via mutagenesis represents an alternative for increasing genetic variability and facilitating breeding. In this sense, coffee seeds cv. Catuaí were treated for 8 h with a solution of sodium azide (NaN3) (0, 50, 75, 100, and 125 mM) and ethyl methane sulfonate (EMS) (0, 80, 160, 240, 320, and 400 mM). The genetic variability induced in coffee plants after mutagenic treatment with sodium azide was determined by RAPD and AFLP analyses. As the concentration of applied NaN3 and EMS increased, the germination, seedling height, and root length decreased. The LD50 values for NaN3 and EMS were between 50-75 mM and 160-240 mM, respectively. For the 12 RAPD primers evaluated, a total of 46 fragments were obtained of which 34 were polymorphic bands (74%). The amplification with six AFLP selective primer combinations allowed the identification of 36 polymorphisms (17.8%). The analysis revealed that both NaN3 and EMS induced variability within the DNA regions amplified with AFLP and RAPD markers. Finally, under field conditions, significant differences were noticed with respect to plant height, number of nodes in the orthotropic stem, and number of branches of the M1 mutant (NaN3-treated) plants compared to the non-mutant plants. Optimal conditions for NaN3 and EMS mutagenesis using seeds were determined and the optimized conditions have been used to generate a NaN3 mutant M1 coffee var. Catuaí population.
