In recent study on design of experiments, the complicate metamodeling has been studied because defining exact model using computer simulation is expensive and time consuming. Thus, some designers often use approximate models, which express the relation between some inputs and outputs. In this paper, we review and compare the complicate metamodels, which are expressed by the interaction of various data through trying many physical experiments and running a computer simulation. The prediction model in this paper employs interpolation schemes known as ordinary kriging developed in the fields of spatial statistics and kriging in Design and Analysis of Computer Experiments (DACE) model. We will focus on describing the definitions, the prediction functions and the algorithms of two kriging methods, and assess the error measures of those by using some validation methods.

Innovation is considered as an implemented innovation in education - in the content, methods, techniques and forms of educational activity and personality education (methods, technologies), in the content and forms of organizing the management of the educational system, as well as in the organizational structure of educational institutions, in the means of training and education and in approaches to social services in education, distance and multimedia learning, which significantly increases the quality, efficiency and effectiveness of the educational process. The classification of currently known pedagogical technologies that are most often used in practice is shown. The basis of the innovative activity of a modern teacher is the formation of an innovative program-methodical complex in the discipline. Along with programmatic and content provision of disciplines, the use of informational tools and their didactic properties comes first. It combines technical capabilities - computer and video technology with live communication between the lecturer and the audience. In pedagogical innovation, the principles reflecting specific laws and regularities of the implementation of innovative processes are singled out. All principles are elements of a complex system of organization and management of innovative activities in the field of education and training. They closely interact with each other, which enhances the effect of each of them due to the synergistic effect. To improve innovative activities in the training of students, today computer technologies are widely used in pedagogy as a science, as well as directly in the practice of the pedagogical process. They have gained the most popularity in such activities as distance learning, online learning, assistance in the education management system, development of programs and virtual textbooks in various subjects, searching for information on the network for the educational process, computer testing of students' knowledge, creation of electronic libraries, formation of a unified scientific electronic environment, publication of virtual magazines and newspapers on pedagogical topics, teleconferences, expansion of international cooperation in the field of Internet education. The article considers computer technologies as the main building material for the entire society. In the modern world, there is a need to prepare a person for life in a multimedia environment. This process should be started as early as possible, because the child's contact with the media is present almost from the moment of his birth.

The study uses an innovative management perspective to investigate the environment of higher education institutions to ensure the survival of universities in Cambodia. This has led Cambodian universities to expand their educational offerings to students in Years 2, 3 and 4. The data was collected through a Google Forms survey to facilitate and accelerate data collection. The sample of 500 students come from three higher education institution by employing multi-stage sampling technique of probability and non-probability sampling methods to ensure representation of the research population. The data were analyzed by using Confirmatory Factor Analysis (CFA) and Structural Equation Model (SEM) to investigate the impact of these determinants on students' satisfaction and loyalty, via answering 54 questions. The results showed that the three Cambodian universities perform well in terms of satisfactory conditions such as transformative quality and university image. There are four issues to which universities need to pay attention, namely, teaching methods, infrastructure facilities, learning material, and academic environment that are yet to meet the needs of students. This study contributes to the principle of innovative management in the context of Cambodian academic environment. The results help to fathom the depth of enhancing quality and institutional survival.

본 연구의 목적은 공무원의 공공봉사동기가 혁신행동에 미치는 영향에서 윤리적 리더십의 매개효과와 조직문화의 조절효과를 분석하는 것이다. 이를 위해 한국행정연구원에서 공무원을 대상으로 조사한 2021년 공직생활실태조사 자료를 활용하였다. 연구결과, 공공봉사동기는 혁신행동과 윤리적 리더십에 긍정적인 영향을 미치고, 윤리적 리더십은 혁신행동에 긍정적인 영향을 미치는 것으로 나타났다. 그리고 윤리적 리더십은 공공봉사동기와 혁신행동의 관계에서 매개역할을 하는 것으로 나타났으며, 조직문화 중 위계문화와 혁신문화에서 조절효과가 있는 것으로 나타났다. 이와 같은 연구결과는 다음과 같은 정책적·실무적 시사점을 제시한다. 첫째, 공무원의 국가 경쟁력을 유지하고 공공조직의 변화에 대응할 수 있는 혁신행동을 향상시키기 위해 윤리적 리더십을 강화할 필요가 있다. 둘째, 최근 공무원 시험 경쟁률이 하락하고 있다. 이는 공무원 조직의 관료주의에 대한 MZ세대의 부정적인 직업관이라 볼 수 있다. 따라서 변화하는 시대에 맞게 공무원 조직도 미래지향적인 혁신문화로 변화할 필요가 있다. 셋째, 국민들과 직접 대면하는 공무원들에게 권한위임 등을 통한 유연성과 자율성을 향상시키는 등의 대안을 통해 혁신문화를 조성하는 방안에 대해 논의가 필요하다.

Purpose: The aim of this study was to identify the individual, job, and organizational factors affecting the individual innovative behaviors among tertiary care hospitals' nurses. Methods: The participants in this study were 230 nurses who have worked more than one year in tertiary care hospitals. Data were collected using self-administered questionnaires that included individual factors (self efficacy, and empowerment), job factors (knowledge and skills for evidence-based practice, and beliefs for evidence-based practice), organizational factors (perceived organizational support), and individual innovation behavior. The SPSS/WIN 25.0 program was used for data analysis which included descriptive analysis, t-test, ANOVA, Scheffé test, Pearson's correlation coefficient, and hierarchical regression analysis. Results: Individual innovative behavior had significant positive correlations with all of individual, job, and organizational factors. The results of hierarchical regression analysis showed that knowledge and skills for evidence-based practice (β=.28, p<.001), self efficacy (β=.25, p=.002), gender (female, β=.23, p<.001), and beliefs for evidence-based practice (β=.17, p=.016) were significant factors influencing on individual innovative behavior. Conclusion: These findings suggest that knowledge, skills and beliefs for evidence-based practice, and self efficacy were linked to individual innovative behaviors. Therefore, education and human resource management improving self efficacy, knowledge, skills and beliefs for evidence-based practice are needed to increase nurses' individual innovative behaviors in tertiary care hospitals.

The use of innovative technologies is one of the promising areas of education development, so the article clarifies the content of the terms "innovation" "pedagogical technology". Our goal is to justify the need to use innovative technologies in education. Innovative technologies are divided into four groups, depending on the appropriate form of educational activity for their use. The development of innovative pedagogical technologies at the present stage of education development should be carried out in accordance with the criteria of technological efficiency, which are presented in the article: scientific; systematic; guaranteed; manageable; mass. Based on the analysis of the process of formation of pedagogical education, the main trends in the information support of teachers in the system of pedagogical education were revealed. Its theoretical and methodological foundations were determined, promising directions and main ways of improving the information support of teachers' education as an organic component of continuous pedagogical education in Ukraine were justified. The conducted study of the state of information support for teachers allowed us to establish that the main functions of scientific and pedagogical information - analytical and predictive, integrative, operational and purposeful informing of various categories of specialists - teachers-are not being implemented enough. This is due to the versatility and complexity of the pedagogical process, the low level and limited range of development of systems of operational differentiated scientific and methodological services for various categories of teachers. Ways to improve the information function of teacher education are determined.

Productivity analysis is the most important and significant method for evaluating management and engineering performance during whole project stage. However, it is very difficult in developing qualitative index to construction industry comparing to other industries. Therefore, analytical hierarchy process (AHP) is one of the methods for overcoming these limitations by checking consistency index using duality comparison. In this study, it is scraped up an application plan and selection for innovative tools by analyzing survey results on tool users and site managers with respect to using Modified-AHP performance measurement method.

For efficient mechanical system optimization, a new two-point approximation method is presented. Unlike the conventional two-point approximation methods such as TPEA, TANA, TANA-1, TANA-2 and TANA-3, this introduces the shifting level into each exponential intervening variable to avoid the lack of definition of the conventional exponential intervening variables due to zero-or negative-valued design variables. Then a new quadratic approximation whose Hessian matrix has only diagonal elements of different values is proposed in terms of these shifted exponential intervening variables. These diagonal elements are determined in a closed form that corrects the typical error in the approximate gradient of the TANA series due to the lack of definition of exponential type intervening variables and their incomplete second-order terms. Also, a correction coefficient is multiplied to the pre-determined quadratic term to match the value of approximate function with that of the previous point. Finally, in order to show the numerical performance of the proposed method, a sequential approximate optimizer is developed and applied to solve six typical design problems. These optimization results are compared with those of TANA-3. These comparisons show that the proposed method gives more efficient and reliable results than TANA-3.

Purpose: The aim of this study was to determine the impact of nursing organizational culture types on innovative behavior and job embeddedness among clinical nurse. Methods: For this study a descriptive correlational study design was used. Participants were 293 nurses who had more than one year work experience. They were recruited from two university hospitals, one in Seoul and one in Gyeonggi province in 2016. Collected data were analyzed using SPSS/WIN 21.0 statistics program. Results: Hierarchy-oriented culture was the highest type of organizational culture perception and innovation-oriented culture, the lowest. Multiple linear regression analyses showed that, when age and total clinical experience were adjusted for, innovation-oriented culture perception was the most significant factor influencing innovative behavior, followed by task-oriented culture and relation-oriented culture in that order ($R^2$=.33, F=24.50, p<.001). Relation-oriented culture perception was the factor most influencing job embeddedness, followed by task-oriented culture and innovation-oriented culture in that order ($R^2$=.48, F=55.98, p<.001). Conclusion: More systematic and sustained organizational efforts are required to improve the hierarchy-oriented culture highly perceived by nurses and to emphasize innovation-oriented, relation-oriented and task-oriented organizational culture to increase innovative behavior and job embeddedness among clinical nurses.
