The reaction of [$[Ni(L)]Cl_2{\cdot}2H_2O$ (L = 3,14-dimethyl-2,6,13,17-tetraazatricyclo[$14,4,0^{1.18},0^{7.12}$]docosane) with 1,1-cyclohexanediacetic acid ($H_2cda$) yields mononuclear nickel(II) complex, [$Ni(L)(Hcda^-)_2$] (1). This complex has been characterized by X-ray crystallography, electronic absorption, cyclic voltammetry and thermogravimetric analyzer. The crystal structure of 1 exhibits a distorted octahedral geometry with four nitrogen atoms of the macrocycle and two 1,1-cyclohexanediacetate ligands. It crystallizes in the triclinic system P-1 with a = 11.3918(7), b = 12.6196(8), $c=12.8700(8){\AA}$, $V=1579.9(2){\AA}^3$, Z = 2. Electronic spectrum of 1 also reveals a high-spin octahedral environment. Cyclic voltammetry of 1 undergoes one wave of a one-electron transfer corresponding to $Ni^{II}/Ni^{III}$ process. TGA curve for 1 shows three-step weight loss. The electronic spectra, electrochemical and TGA behavior of the complex are significantly affected by the nature of the axial $Hcda^-$ ligand.

This paper aims to develop a conceptual framework for evaluating the impact of factors influencing the decision of Vietnamese students to study English in the Philippines. The empirical analysis used data from the survey data of 318 respondents living in Vietnam. Comprehensive, valid, and reliable tools (SPSS 26 software) are used to analyze and verify the gathered data, and the hypotheses developed. The results identified the factors that affect the decision of Vietnamese students to study English in the Philippines include knowledge and awareness, personality recommendation, cost issues, environment, geographic proximity, and social link. Based on the overall findings of this study, several implications are presented for educational practices in academies and schools about English teaching in the Philippines. To increase the ability to get students to study English in the country, it is important that schools or academies must understand the demands of students regarding the academic environment, and in particular, to know what factors determine the decision from the customers' point of view. This study contributes significantly to the understanding of agencies and educational managers about the student's choice behavior in the context of the need to improve foreign languages and, thus, help improve the competitiveness of agencies and English schools.

Ubiquitous learning has aroused great interest and is becoming a new way for foreign language education in today's society. However, how to increase the learners' initiative and their community cohesion is still an issue that deserves more profound research and studies. Emotional intelligence can help to detect the learner's emotional reactions online, and therefore stimulate his interest and the willingness to participate by adjusting teaching skills and creating fun experiences in learning. This is, actually the new concept of smart education. Based on the previous research, this paper concluded a neural mechanism model for analyzing the learners' emotional characteristics in ubiquitous environment, and discussed the intelligent monitoring and automatic recognition of emotions from the learners' speech signals as well as their behavior data by multi-agent system. Finally, a framework of emotional intelligence system was proposed concerning the smart foreign language education in ubiquitous learning.

The purpose of this article is to examine the relationship between sin and grace represented in The Power and the Glory. This work is composed of two thriller patterns of the pursuer and the pursed. The first pursuit is that the whisky priest, the representative of religious order is pursued by the lieutenant, the representative of secular order. And the second pursuit is that the whisky priest is trying to escape from God. In the course of his flight from God the whisky priest discovers his sinful nature and this self-recognition helps him restore his proper relationship with God. When he was a young priest he had religious piety, but he didn't feel true love for others. Ironically, after he is corrupted he finds his sinful nature and regrets his wrong behavior. He then comes to understand God's will and his responsibility to have love for the miserable human beings. The whisky priest is willing to accept his destiny as a martyr, after having repented his sins to God. Though the lieutenant captures the whisky priest and executes him, he doesn't feel triumph or hope but feels empty. The Power and the Glory shows us the irony that the lieutenant's power is a symbol of his weakness, while the priest's weakness is a symbol of his power.

This study was conducted to develop and effective strategy for environmental education. At first, the environmental education strategy through personalization of environment was proposed. Then students in a middle school participated the program according to the strategy and its. effect was investigated. The strategy was designed in basis of the role of the limbic system in brain and involved field-oriented experience such as viewing the non-personal environment as the personal environment. Gokneung stream was selected as the site to conduct this environmental education. Students investigated water quality by senses and biological method. The same content was taught for the classroom group and simple outdoor group selected for the comparison by traditional instructional method. The pre- and post-test by the instrument to test environmental attitude, qualitative questionnaire, cognitive test, the pre- and post-interview were conducted to investigate the effect the program. The achievement of the classroom group(personalization group). But the change of the attitude toward environment of personalization group between pre- and post-test was significantly higher than the classroom group. In qualitative questionnaire and pre- and post-interviews, attitude toward environment differed between two group. The behavioral change to discover and to solve environmental problems was demonstrated in case the personalization group, but was unclear in the classroom group. These results indicated the environmental education strategy through personalization of environment was an effective strategy to change the awareness, attitude and behavior toward the environment compared with a traditional teaching strategy.

Purpose: The aim of this study was to evaluate perception and satisfaction with Health Education for elementary school students in grade 5 and 6, using data on national health education gathered since March, 2009. Methods: Data were collected by way of a questionnaire, from 475 elementary school students in grades 5 and 6 from February 1~15, 2010. Statistical analysis of collected data was performed using frequency, t-test, Pearson's correlation coefficient, and hierarchical multiple regression analysis, using SPSS 18.0 software. Result: Levels of health promoting behavior, interest, importance, and satisfaction were relatively high, respectively, and those of students in grade 5 were higher than those of students in grade 6. Levels of Satisfaction with frequency and educational environment were relatively low. Among the factors found to influence satisfaction with health education, interest in health education was found to be the most influential(grade 5:${\beta}$=.279, p<.001, grade 6:${\beta}$=.306, p<.001). Conclusion: Students expressed a high level of satisfaction with regular health education. Expansion of health education frequency and health education-only-classrooms is needed. To improve the effect of health education, constant acquisition of knowledge of subjects' perception and satisfaction is needed. In addition, contents and teaching methods that showed low level of satisfaction should be reformed.

This article derived a hybrid coupling technique using the higher-order displacement polynomial and three soft computing techniques (teaching learning-based optimization, particle swarm optimization, and artificial bee colony) to predict the optimal stacking sequence of the layered structure and the corresponding frequency values. The higher-order displacement kinematics is adopted for the mathematical model derivation considering the necessary stress and stain continuity and the elimination of shear correction factor. A nine noded isoparametric Lagrangian element (eighty-one degrees of freedom at each node) is engaged for the discretisation and the desired model equation derived via the classical Hamilton's principle. Subsequently, three soft computing techniques are employed to predict the maximum natural frequency values corresponding to their optimum layer sequences via a suitable home-made computer code. The finite element convergence rate including the optimal solution stability is established through the iterative solutions. Further, the predicted optimal stacking sequence including the accuracy of the frequency values are verified with adequate comparison studies. Lastly, the derived hybrid models are explored further to by solving different numerical examples for the combined structural parameters (length to width ratio, length to thickness ratio and orthotropicity on frequency and layer-sequence) and the implicit behavior discuss in details.

Objective: The goal of this study is to develop an instrument for measuring the quality of teacher support for children's play (age 3-5) based on the Play Practice Resources for Teachers presented in the 2019 revised Nuri Curriculum. Methods: The subjects of this study were 333 early childhood educators. Exploratory and confirmatory factor analysis, as well as correlation analysis were all performed to confirm construct validity and concurrent validity. The reliability of each factor was verified using Cronbach's alpha. Results: The Preschool Teacher Play Support Scale (PTPSS) was finalized with 25 items, which included the following four sub-factors: interaction, play materials, play space, and play safety. The concurrent validity was also confirmed through significant correlations between the existing measures such as the Teacher Self-Efficacy Scale, the Teaching Efficacy Scale for Play, and the Teacher-Toddler Interaction Scale. The reliability of each factor was also desirable. Conclusion/Implications: The PTPSS was verified as a sound measure quantifying the play support behavior of teachers who respect the autonomy and initiative of young children which is being pursued by the 2019 revised Nuri Curriculum.
