Currently composite manufacturing process, such as linear friction welding plus NC machining, is the main method for the manufacturing and repairing of complex parts with integrated structure. Due to different datum position and inevitable distortion from different processes, it is important to ensure sufficient machining allowance for complex parts during the NC machining process. In this paper, a workpiece localization approach for machining allowance optimization of complex parts based on CMM inspection is developed. This technique concerns an alignment process to ensure sufficient stock allowance for the single parts as well as the whole integrated parts. The mathematical model of the constrained alignment is firstly established, and then the symmetric block solution strategy is proposed to solve the optimization model. Experiment result shows that the approach is appropriate and feasible to distribute the machining allowance for the single and whole parts for adaptive machining of complex parts.

In this paper, as a liberal arts course for non-majors, we proposed a supervised learning artificial neural network parameter optimization method and a basic education method for activation function to design a basic artificial neural network subject curriculum. For this, a method of finding a parameter optimization solution in a spreadsheet without programming was applied. Through this training method, you can focus on the basic principles of artificial neural network operation and implementation. And, it is possible to increase the interest and educational effect of non-majors through the visualized data of the spreadsheet. The proposed contents consisted of artificial neurons with sigmoid and ReLU activation functions, supervised learning data generation, supervised learning artificial neural network configuration and parameter optimization, supervised learning artificial neural network implementation and performance analysis using spreadsheets, and education satisfaction analysis. In this paper, considering the optimization of negative parameters for the sigmoid neural network and the ReLU neuron artificial neural network, we propose a training method for the four performance analysis results on the parameter optimization of the artificial neural network, and conduct a training satisfaction analysis.

Purpose: The purpose of this study was to construct the education applying the Havruta method for nursing students and to investigate the effects on self-directed learning ability, critical thinking, and learning commitment. Methods: A nonequivalent control group pre-posttest design was used. The participants were 63 nursing students (experimental group, n=31; control group, n=32) at two universities. The experimental group received education applying the Havruta method for five weeks. The study was conducted from September 1 to November 30, 2022. The data were analyzed using IBM SPSS 27.0 for an χ² test, Fisher's exact test, independent t-test, and Mann-Whitney U-test. Results: The experimental group had a significant increase in self-directed learning ability (z=-2.13, p=.033). However, there was no significant difference in critical thinking competency (t=0.64, p=.524) and learning commitment (t=0.04, p=.969) between the two groups. Conclusion: The Havruta method is an effective nursing education tool for self-directed learning ability. The result of this study could be a guide for nursing professors in designing and implementing educational programs that apply the Havruta method. In the future, research that applies the Havruta method and evaluates its effectiveness in nursing education programs should be continued.

This paper is concerned with the design and construction of navigational interfaces on the web-based multimedia courseware, in particular for the education of elementary school children. Three different types of navigational strategies for the different structures of information are discussed. For hierarchically organised subject material, a single menu list is considered to be the most appropriate means of navigation. The interface of the 'Study of the Internet' provides a combination of child and sibling menus and sequential tools. The menus are used for navigating topics and subtopics, and the sequential method is used for navigating pages. The final navigational interface has the advantages of allowing the student flexible navigation, and proving an indication of progress through the subject material. Finally, the combination of menu and sequential navigational methods allow a student to maintain context, whilst navigating through different levels of hierarchical information. It thus reduces the danger that the student will lose their way, without overconstraining the navigational path.

Purpose: This study investigated the effect of an AIDS education program of nursing junior students on knowledge, attitudes, fear of contagion, and nursing intentions about AIDS. Method: The study was conducted in a university in Chungnam province from March, 2000 to May, 2001. Research design of this study was a nonequivalent control group, non-synchronized design. A traditional lecture education was given to the control group. The experimental group received a multi-media education using video tape and group discussion as well as traditional lecture education. Data were collected 1 month before and after education. The SPSS program was used to analyze the data. Results: The results of this study were as follows: There were significant differences in the mean of knowledge (t=4.227, p=.000), prejudice (t=-2.281, p=.025), social interaction (t= 4.144, p=.000) between experimental group and the control group. But, there were no significant differences in the mean of fear of contagion (t=-7.320, p=.467) and nursing intention (t=.800, p=.427) between the two groups. Conclusion: The findings of this study showed the benefits of providing educational interventions for improving knowledge and attitudes, but didn't show any significant changes on fear of contagion and nursing intention. Therefore, to reduce fear of contagion and increase nursing intention, various teaching strategies need to be further studied and evaluated.

When the design profession started, design targets were mainly static hardware centered products. Due to the development of network and digital technologies, new products with dynamic and software-hardware hybrid interactive characteristics have become one of the main design targets. To accomplish the new projects, designers are required to learn new methods, tools and theories in addition to the traditional design expertise of visual language. One of the most important tools for the change is effective and rapid prototyping. There have been few researches on educational framework for interactive product or system prototyping to date. This paper presents a new model of educational contents and methods for interactive digital product prototyping, and it's application in a design curricula. The new course contents, integrated with related topics such as physical computing and tangible user interface, include microprocessor programming, digital analogue input and output, multimedia authoring and programming language, sensors, communication with other external devices, computer vision, and movement control using motors. The final project of the course was accomplished by integrating all the exercises. Our educational experience showed that design students with little engineering background could learn various interactive digital technologies and its' implementation method in one semester course. At the end of the course, most of the students were able to construct prototypes that illustrate interactive digital product concepts. It was found that training for logical and analytical thinking is necessary in design education. The paper highlights the emerging contents in design education to cope with the new design paradigm. It also suggests an alterative to reflect the new requirements focused on interactive product or system design projects. The tools and methods suggested can also be beneficial to students, educators, and designers working in digital industries.

In this paper, Capstone Design Education Program Learning Model was developed and recommended in order to foster convergent talents armed with practical competences and real cooperative capabilities. In this era of convergence and creativity, the fashion world needs human resources with cooperative skills and true professional abilities. A case analysis, an in-depth interview, and 1,2 test method were used for data acquisition and analysis. The summary of this study is described below. First, this program needs to complement the NCS fashion design learning module. Second, material changes to creativity and practical competencies - knowledge, skills, and attitudes - of the students are assessed after applying Capstone Design to the NCS fashion design learning model. Third, the process of converging fashion curriculum with IT and electronic technology, developing a fashion design learning program, and applying the Capstone Design was tested to prove the effectiveness of convergent fashion design education. Among the changes observed between the trial and control groups, it was confirmed that sub-factors of creative personality, i.e. self-assurance and openness, were increased along with knowledge, core competences including communication capability, and self-directed learning capability. The greatest improvement on the technological side was observed in IT literacy while ability to respond to changes was also increased. Besides, effects were demonstrated in behavioral factors such as initiative, spirit of challenge, experience, and openness. Lastly, the Capstone Design Education Program Learning Model was proposed in order to foster convergent talents in the fashion world.

"Color" education aimed at cultivating creativeness and expressive techniques in the education of visual art, in the college of art and design, should be balanced with "form" education; nevertheless, the present situation at Korean universities is such that the overall environments of "color" education are far too inferior to those of "form" education.The problem is, among other things, that the curriculum of visual art education is centered around formal education; in addition, color education courses consist mostly of theoretical issues, not experimental, first-hand-experience-oriented activities that are best suited for the characteristics of the language of color as a visual language, thereby making it difficult to expect the efficiency of education.Particularly, it is a serious problem that the courses dealing with color are not offered in a step by step fashion, from the most elementary, to the intermediate, working up to the most advanced level. Another problem is that those people involved in color education seldom have an expertise in their area; furthermore, the educational environment, educational tools, and the content of the texbooks are far from being ideal.Moreover, it is a grim reality that most color theory courses that have been offered end up being a lecture of "general, basic" color theories, ignoring the students' diverse specialization areas.As a way of normalizing color education, rationalizing the curriculum and initiating the professorship exclusively teaching color education have to be introduced, so that we can increase the depth of color education and individualize the contents of color education according to the students' needs. It is believed that the introduction of the "color-education-only" professorship will greatly facilitate our effort to devise an efficient educational method, to determine the scope of individualized color education, and to improve the ovarial educational environment (such as facilities, instruments, and teaching materials) necessary for an in-depth education.ments, and teaching materials) necessary for an in-depth education.
