The purpose of this study is to develop an e-teaching portfolio to perform a teaching portfolio of an instructor on the web. I order to carry out this study, an initial model of the e-teaching portfolio was developed through systematic literature review, and the final e-teaching portfolio was developed by selecting and applying five students, then modifying and supplementing them. The study period was from May 1 to May 20, 2022. As a result of the study, the components of the finally developed e-teaching portfolio are Step 1: Understanding oneself, Step 2: Goal setting, Step 3: Learning strategy, Step 4: Self-check. In conclusion, the program developed through this study is a convenient function that can process everything in one place by connecting the fragmented teaching results, and the developed e-teaching portfolio can promote interaction between individuals by building a community. It has possible characteristics. In order to systematically activate the e-teaching portfolio developed through this study, it is necessary to establish an online management system for systematic operation. Furthermore, an institutional device is needed to guarantee the result of the developed e-teaching portfolio. In order to continuously manage the quality of the teaching portfolio, extrinsic rewards that stimulate the instructor's intrinsic motivation should be provided.

This is a review of the theory and practical uses of the $Hom{\grave{e}}s$' systematic variations in the fertilizer experiments. General characteristics of the method are as follows : 1 ) It could be recommended as a reasonable met hod for fertilizer experiments in order to improve the weak points in the conventional methods. 2 ) This met hod is a determination of the total amount of nutrients and the relative proportion of each nutrient in the total. 3 ) Concerning of the high yields of crops this met hod should be adapted for the systematic fertilization. 4 ) This is an usable method not only for the macro- but also micro elements investigations.

In order to examine the educational effects and future directions of unplugged activities, we conducted a systematic review of Korean journals and theses from 2007 to 2016. Three kinds of database were used for systematic review: RISS, KISS, and E-article, and were performed searches using options such as 'unplugged' and 'play-centered'. Based on the protocol selected in the framework of the systematic review, 37 articles were selected analyzed in terms of research status, research subjects, research methods, research hubs, study mechanisms, educational methods, and research effects. Unplugged activities were the most popular among elementary school students. Educational effects were found to have significant effects on academic achievement, problem solving ability, and logical thinking ability. In the affirmative domain, there was a significant effect on interest, curiosity, and motivation. Based on the results of the analysis, the characteristics and implications of Unplugged activities and present the direction of future education were discussed.

This study systematically collected and analyzed the results of previous studies on the stress of clinical dental prctice for dental hygiene students. The data were collected according to the systematic review guidelines of PRISMA(Preferred Reporting Items for Systematic Reviews and Meta-analysis) and 25 ariticles were used in the final analysis. In order to measure clinical dental practice, 4 measuring tools were used. As a result of literature analysis, the lower the satisfaction, the higer the stress of clinical dental practice. Personal relationship, role and activity, ideal and value were very important factors. The purpose of this study is to analyze the relationship between clinical dental practice and various variables and to investigate the improvement of clinical dental practice based on the results of this study.

This study systematically collected and analyzed the results of previous studies on job satisfaction of dental hygienists and analyzed the job satisfaction measurement tools and related factors. It was conducted according to the systematic review guidelines of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis), and 44 articles were used in the final analysis. In order to measure job satisfaction, ten measuring tools were used. All the measuring tool were developed overseas and they were modified. As a result of the literature analysis, the higher the job satisfaction, the more negative correlation was found between turnover intention and job stress, and positive correlation was found between organizational commitment and professional occupation. The purpose of this study is to analyze the relationship between job satisfaction and various variables and to investigate the improvement of job satisfaction of dental hygienist based on the results of this study.

Chemical reactions in cells are so complicated and abstract that students have difficulty in understanding them. In this study, classes with the application of systematic analogies used at the interpretation of experimental results were taught to 10th-grade students in order to help them to understand the concept of enzymes, which play an important role in chemical reactions in cells. Effects of the classes on their understanding of the concept of enzymes and the role of systematic analogies were analyzed. The gap of understanding between the test group and the control group was significant at 0.05, indicating that systematic analogies are effective for students' understanding of the concept of enzymes. Looking into the concept of enzymes by individual element, the effect of systematic analogies was shown to be large for equilibrium-like processes, such as the enzyme structure change caused by temperature and pH; and the continuous and random actions of enzymes, which students have difficulty in understanding. For these processes, systematic analogies played a positive role in improving their conceptual status. The visualizations and familiarity of analogs increased their intelligibility regarding the concept of enzyme. Also, the systematic analogies increases their plausibility by helping to connect phenomena, taking place in the enzyme reaction experiments, with scientific concepts as scaffold. Accordingly, it was possible to explain experimental results as scientific concepts in a consistent manner. In addition, analogies familiar to students played a positive role from the affective perspective by promoting students' interest and helping them to approach hard scientific concepts.

Entire functions have been investigated so popularly to have been divided into a large number of specialized subjects. Even the limited subject of entire functions is too vast to be dealt with in a single volume with any approach to completeness. Here, in this paper, we choose to investigate certain interesting results associated with the comparative growth properties of iterated entire functions using (p, q)-th order and (p, q)-th lower order, in a rather comprehensive and systematic manner.

This paper deals with planning of order-picking warehouse considering the batch order picking for transportation equipments to pick consumers' orders at a time among order-picking methods and a systematic approach method in order to analyze the order-picking warehouse which can perform optimal operation. To estimate an operating time of transportation equipments to carry out order-picking, this paper suggests three operations : first, to design the refrigerated warehouse using warehouse design parameters, second, to calculate the travel time of transporters considering four types of times with the probabilistic picking frequency, and third, to analyze an order-picking warehouse to construct a simulation model with the AutoMod as a simulation tool. We apply this model to a refrigerated warehouse company in Busan.
