The purpose of this study was to examine high school second graders' understanding of the basic nature of logarithm, the major type of error they made about logarithmic function and the cause of such an error, and to seek ways to instruct it better. For that purpose, three research questions were posed: 1. Investigate how much high school students in their second year comprehend the nature of logarithm. 2. Analyze what type of error they make about logarithmic function. 3. Analyze the cause of their error according to the selected error models and how it could be taught more efficiently. The findings of this study were as below: First, the natural science students had a better understanding of the basic nature of logarithm than the academic students. What produced the widest gap between the two groups' understanding was applying the nature of logarithm to the given problems, and what caused the smallest gap was the definition of logarithm and the condition of base. Second, the academic students had a poorer understanding of the basic nature of logarithmic function graph and of applying the nature of logarithm to the given problems. Third, the natural science students didn't comprehend well the basic nature of logarithmic function graph, the nature of characteristics and mantissa. Fourth, for all the students from academic and natural science courses, the most common errors were caused by the poor understanding of theorem or nature of the ［E4] model. Fifth, the academic students made more frequent errors due to the unfamiliar signs of the ［El］ model, the imperfect understanding of theorem or nature of the ［E4］ model, and the technical part of the ［E6］ model. Sixth, the natural science students made more frequent errors because of the improper problem interpretation of the ［E2］ model and the logically improper inference of the ［E3］ model.

The purpose of this study is to investigate the teacher's perception of maker education and to suggest the direction of teacher education curriculum for maker education in order to explore the possibility of applying maker education to early childhood education. To this end, a survey was conducted on the perception of maker education for preschool teachers. As a result of the data analysis, the perception of the concept, meaning, and educational environment of maker education were low, while the effectiveness, importance, value, continuous application and development of maker education were highly recognized and the necessity of maker teacher education and the educational environment was suggested. Based on the survey results, the teacher curriculum composition was classified into basic and advanced courses. The basic course included basic contents to understand maker education and maker space. The advanced course included information on how to use various tools, materials and digital media, how to conduct and evaluate maker education to apply maker education. The teacher curriculum composition for maker education can suggest basic directions for developing teacher education programs and strengthening the digital teaching competency of teachers in the future.

The era of the Fourth Industrial Revolution is increasingly demanding mathematical competencies for virtual reality (VR), artificial intelligence (AI) and the like. In this context, this study intended to identify the basic mathematical competency levels of university freshman students in radiology department and to provide basic data thereon. For this, the diagnostic assessment of basic learning competencies for the domain of mathematics was conducted from June 17, 2019 to June 28, 2019 among 78 freshman students of radiology department at S university and D university. As a result, the university students' overall basic mathematical competency levels were diagnosed to be excellent. However, their levels in the sectors of the geometry and vector and the probability and statistics were diagnosed to be moderate, with the mean scores of 2.61 points and 2.64 points, respectively, which were found to be lower than those of the other sections. As for basic mathematical competency levels according to genders, the levels of male students and female students were diagnosed to be excellent, with the mean scores of 17.48 points and 16.29 points, respectively, showing no statistically significant difference (p>0.05). Given the small number of subjects and regional restriction, there might be some limitations in the generalization of the findings of the present study to all university freshman students and all departments. The above results suggest that it is necessary to implement various programs such as student level-based special lectures for enhancing basic mathematical competencies relating to major in order to improve the basic mathematical competencies of freshman students in radiology department, and that it is necessary to increase the students' mathematical competencies by offering major math courses in the curriculum and applying teaching-learning methods matching students' levels.

Since the computer is becoming more and more indispensible tool in every fields of the modern society, it is needed and desirable to utilize the computer as a basic tool from the very early stage of the education process. Recently Maple is gaining its popularity as a comprehensive mathematical software with its power of symbolic calculations and graphics as well as its great numerical computational ability. We demonstrate the suitability of this software as a tool for the mathematical education and presents several examples of the applications of Maple. For the middle and the high school mathematics courses, we give the application examples for the quadratic functions and their graphs, statistics, the three dimensional shapes, algebraic problems. Through the examples, we confirm that mathematical education can be much more effective and simple by using Maple. If we establish computer-assisted mathematical classes, we can draw more attention and excitement from the attendants than traditional classes and eventually improve more rapidly their problem-solving ability On the other hand, the excess of the computer-aided education give to obstacle of psychological, not to be passing over the fact.

A field study was carried out to find out the effective chemical for controlling algae without visual injury on creeping bentgrass golf greens. The results were as follows. 1. Chlorothalonil(75%), Metalaxy(7.5%)+Mancozeb(56%) and Mancozeb(75%) did not injure creeping bentgrass. Only chlorothalonil(75%) effectively controlled algae regardless of concentration among above mentioned 3 fungicides. 2. Mancozeb frequently used on golf courses showed about 50% effect on controling algae in this study. 3. Mancozeb(75%)+Copper hydroxide(73%) and Mancozeb(75%)+Streptomycin(100%) had good effects on algae control while injuring creeping bentgrass. 4. Copper hydroxide(73%) and copper sulfate basic(58%) $including\ulcorner$Cu$\lrcorner$showed effective algae control but caused injure creeping bentgrass. 5. Streptomycin has been scarcely used on golf greens but streptomycin(20%) 0.1g a.i/$\m^2$ had good control of algae and durability without injuring creeping bentgrass.
