In this study, we want to analyze the aspect that required in the classroom for the operation of NCS-based curriculum, the interest of specialized subject teachers on implementable teaching and learning methods. As a result, the overall interest in teaching-learning method of specialized subject teachers was similar to that of non-user patterns among four types of interest patterns. In other words, specialized subject teachers want to know more about teaching-learning method for applying NCS-based curriculum, but we are only aware of the general facts at present, and it seems that there is low interest in actual operation. In addition, there was no statistically significant difference in the degree of interest in the teaching-learning method according to general variables(gender, related training experience, career, and curriculum group) of the specialized subject teachers. The specialized subject teachers are not well aware of the influence of the teaching-learning method according to the introduction of NCS-based curriculum, and to that end, there was little interest in collaboration with colleagues.

Globally, the change in higher education is gradually moving toward a trend that seeks a change in innovative higher education through the revitalization of digital-based education. Accordingly, this study designed a customized education model based on e-learning that can be used in undergraduate education and development of lifelong vocational skills. The use of online learning platforms and the expansion of education are major factors that change the overall higher education system as the form and content of curriculum changes around the world. In order to establish a customized education model using online learning platform, this study analyzed major overseas advanced education cases and selected the basic direction of customized learning as personalized learning, competency based learning, and training for talents leading the 4th Industrial Revolution. Then, FGI was conducted for undergraduate and lifelong vocational ability development experts. As a result, a customized education model using an online learning platform was derived from a degree-type model available in undergraduate education and a non-degree-type model available in the field of lifelong vocational ability development, and each operation strategy was suggested.

The purpose of the study was to examine cooperative education between industry and school recognized by tentatively called managers of cooperative education, teachers in charge of cooperative education between industry and school, in vocational high school in Incheon Area. In order to accomplish the study purpose, the study conducted a research through questionnaire and examined their recognition for cooperative education between industry and school focusing on curriculum (purpose and content), operational system including supporting system (establishment and operational level) and educational type (process, effectiveness, problems and reinforcing measures). The study conducted a survey using Likert 5 score scale and analyzed the survey results using technical statistics such as frequency, average, standard deviation, etc. From the comprehensive results from the survey, it was found that although outcomes from industry-school cooperation are relatively high, participation is insufficient and intermediating organizations connecting concerned parties and mediating them are not enough because recognition and will of interested parties of industry-school cooperation are not sufficient. In addition, policies, legal and systematical and financial infrastructure for activation and efficiency of industry-school cooperation are not established perfectly, therefore, there are a lot of things to be improvement in operation. In particular, it was observed that establishment of internal organization and infrastructure for the number of workers in vocational training organizations are decisively inadequate.

The study tried to investigate perception of the importance and educational needs of job performance competency of National Competency Standards based vocational education curriculum in technical specialized high schools and meister high schools. For this, the survey was conducted targeting 269 specialty subject teachers in technical specialized high schools and meister high schools. And the results are as follow: First, job performance competency were divided into 5 categories(curriculum guidance, school life guidance, class management, extraordinary activities and administrative duties) and 34 sub-categories. Second, higher importance values were curriculum guidance, extraordinary activities and school life guidance. Higher educational needs values were curriculum guidance, extraordinary activities and administrative duties in categories. Third, higher importance values were construction and reconstruction of NCS learning modules, organization and manage of NCS based vocational education curriculum, guide of the new laws and employment, student records manage, research activities of NCS, hands-on-background training, NCS projects in sub-categories. Fourth, the results show that the NCS experienced teachers more highly evaluated the importance and educational needs of the job performance competency than the NCS inexperienced teachers did.

With the rapid development and introduction of digital technologies, both everyday human life and technological processes of any production are changing, which stimulates the transformation of the economy and education. Digital technologies are not only a tool, but also a living environment of modern human, which opens up new opportunities: learning at any convenient time, continuing education, the ability to form individual educational learning trajectories and more. However, the digital environment requires teachers to take a modern approach to the organization of the educational process, the formation of new skills and abilities to work in the digital educational environment. As a result of the study, it was found that the system of vocational education should provide training for masters of industrial training who have a high level of digital competence. The purpose of the article is to single out, theoretically substantiate and determine the level of formation of structural components of digital competence of future masters of agricultural training. The structure of digital competence of agricultural master was analyzed on the basis of domestic and foreign scientists researches. Systematized research results indicate that digital competence consists of four components: motivational-value (combination of internal and external motives for the use of digital technologies in future professional activities), cognitive (a set of theoretical knowledge, skills and abilities of future master of industrial training to effectively build educational process with the use of digital technologies), activity-professional (expansion and deepening of knowledge, skills, necessary skills for effective implementation of digital technologies in the educational process) and evaluative-reflexive (ability to analyze and self-analyze own activities and its results taking into account professional characteristics, self-realization in professional activities through the use of digital technologies). These components are comparable with the indicators that describe the knowledge, skills and abilities needed by the future master of industrial training to organize the modern educational process. A questionnaire was conducted to determine the levels of this competence formation, which allows us to conclude that it is necessary to increase the level of formation of all components of digital competence of future masters of industrial training in agriculture. The results of the study can be used as a basis for the development of disciplines that form the special competencies of masters of industrial training in agriculture and programs of advanced training of teachers.

An accurate plate theory for assessing sandwich structures is of interest in order to provide precise results. Hence, this paper develops Layer-Wise (LW) theory for reaching precise results in terms of buckling and vibration behavior of Functionally Graded Carbon Nanotube-Reinforced Composite (FG-CNTRC) annular nanoplates. Furthermore, for simulating the structure much more realistic, its edges are elastically restrained against in-plane and transverse displacement. The nano structure is integrated with piezoelectric layers. Four distributions of Single-Walled Carbon Nanotubes (SWCNTs) along the thickness direction of the core layer are investigated. The Differential Quadrature Method (DQM) is utilized to solve the motion equations of nano structure subjected to the electric field. The influence of various parameters is depicted on both critical buckling load and frequency of the structure. The accuracy of solution procedure is demonstrated by comparing results with classical edge conditions. The results ascertain that the effects of different distributions of CNTs and their volume fraction are significant on the behavior of the system. Furthermore, the amount of in-plane and transverse spring coefficients plays an important role in the buckling and vibration behavior of the nano-structure and optimization of nano-structure design.
