This paper presents the development of embedded network educational system. This is an educational equipment which enables user to have training over Network Configuration and Embedded network programming practice on Internet environment. The network education system is developed on embedded environment. based on using ethernet interface. On the development environment. PAX255 VLSI chip is used for the processor, the ADSv1.2 for debugging, uC/OS276 for RTOS. The system software was developed using C language. The ping program provided an educational environment for the student to compile and load it to run after doing practice of demonstration behavior. Afterwards programming procedure starts the step-by-step training just like the demonstration function. In other words, programming method how to design the procedure of ARP operation and ICMP operation is explained.

As the demand for the talented with computing thinking and programming skills increases the importance of coding education is increasing. Although various coding instructor training programs have been implemented nationwide, little research has been conducted analyzing the current status and contents of coding instructor training programs. Therefore, this thesis presents the design, development process and managing strategies of the 'Coding Instructor Training Courses for 4C Talent Development'. The training program consists of introductory courses and practical coding courses. In the introductory courses, learners acquires the basic knowledge required of coding instructors, and then proceeds to the practical courses to systematically learn the pedagogical knowledge and skills required to educate learners from kindergarten through high school. The case study introduced in this paper is expected to provide useful information to the educators planning and managing the coding instructor training program in the future.

The COM curriculum provides first a core of mathematics for all students, and then offers opportunities for students to enter different streams of mathematics studies. The flexible curriculum (COM) is certainly welcome as it focuses on a transition from concrete to conceptual mathematics and on sequentially learning the power of mathematical language and symbols from simple to complex. This approach emphasizes the use of computers in mathematics education in the upper secondary grades. In Mathematics A, one unit is developed to computer operation, flow charts and programming, and computation using the computer. In mathematics B, a chapter addresses algorithms and the computer where students learn the functions of computers, as well as programs of various algorithms. Mathematics C allots a chapter for numerical computation in which approximating solutions for equations, numerical integration, mensuration by parts, and approximation of integrals. But, unfortunately, they do not have any plan for the cooperation study.

The curriculum of programming education including algorithm has been recognized as a very important subject to many students majoring in natural sciences and engineering including electronic engineering and computer related departments. This study analyzed usability of the learning system of programming languages using basic algorithms so as for students to easily learn basic algorithm among the entire programming curriculum. The results show that the grade of learning achievement of experimental group using the learning system is 15 points higher than that of non-experimental group and the grade of interest, concentration, effectiveness, understanding, convenience, suitability, and attending a lecture in the next semester are 4 points or more of 5 points criterion.

Although mechatronics education in a mechanical engineering curriculum is recently recognized as important, its experimental education has been done generally in the laboratory equipped with all the apparatus and could not be done at home by students. This paper introduces experimental educations on mechatronics, e.g., digital logic circuits, 7-segment LED drive, square wave generation, microcontroller programming using assembly and C languages, timer interrupt, and step motor drive using a small 5 V power supply, a breadboard, various electronic and electric components, a microcontroller and its programmer, a step motor, and a student's PC. In the developed mechatronics course, experimental educations are scheduled in parallel with content's lectures together, and cheap and economic experimental environment is prepared for students in which students can easily practice experimental works in advance or later at home by themselves.

컴퓨터 프로그래밍 학습은 추상적인 개념을 이해하고 주어진 문제를 스스로 해결하도록 한다. 기존 초등학교 프로그래밍 교육에서 BASIC, C와 같은 절차적 프로그래밍 언어에 대한 연구는 많이 있지만 JAVA와 같은 객체지향 프로그래밍 언어를 통한 교육은 찾아보기 힘들다. 본 논문에서는 구조 중립적이며, 분산 인터넷 환경에 적합한 특성을 가지고 있는 객체지향 JAVA 프로그래밍 학습 시스템을 개발하여, 초등학교 학생들로 하여금 활용하도록 하였다. JAVA 학습 시스템 구현을 통한 객체지향 프로그래밍 교육은 초등학생들의 논리적 사고력을 향상시키고, 수학, 과학 과목의 학습 성취도에 긍정적인 영향을 준다는 것을 현장 학습 실험으로 확인하였다. 더불어 컴퓨터에 대한 흥미도가 상승하였다.

Drones are increasingly used in logistics delivery due to their low cost, high-speed and straight-line flight. Considering the small cargo capacity, limited endurance and other factors, this paper optimized the pickup and delivery vehicle routing problem with time windows in the mode of "truck+drone". A mixed integer programming model with the objective of minimizing transportation cost was proposed and an improved adaptive large neighborhood search algorithm is designed to solve the problem. In this algorithm, the performance of the algorithm is improved by designing various efficient destroy operators and repair operators based on the characteristics of the model and introducing a simulated annealing strategy to avoid falling into local optimum solutions. The effectiveness of the model and the algorithm is verified through the numerical experiments, and the impact of the "truck+drone" on the route cost is analyzed, the result of this study provides a decision basis for the route planning of "truck+drone" mode delivery.

웹을 기반으로 한 프로그래밍 교육 시스템에 관하여 많은 연구가 이루어져 왔으나 대부분의 연구는 강의 노트의 제공 방법, 또는 하이퍼링크 상에서의 효과적인 네비게이션 방법과 같은 원격 교육 시스템에 국한된 내용이었다. 그러나 프로그래밍 교육은 그 특성상 강의노트의 제공 방법이나 하이퍼링크 상에서의 효과적인 네비게이션 방법보다도 많은 양의 과제를 통한 연습 기회의 제공과 각 과제에서의 교수자와 학습자간의 친밀하고 개인적인 상호작용이 학습자의 학업성취도에 더욱 큰 영향을 미친다. 본 논문에서는 원격 교육 시스템의 관점에서 더 나아가 교수자가 학습자에게 많은 양의 과제를 통한 연습의 기회를 부여 할 수 있고 각 과제당 교수자와 학습자간의 상호작용을 극대화할 수 있는 웹 기반 프로그래밍 교육 시스템을 구현하였다. 웹 기반 프로그래밍 교육 시스템은 학습자에게 시간과 장소에 구애됨이 없이 웹 브라우저를 이용하여 프로그램을 코딩하거나 컴파일할 수 있고 SPLINT를 통한 분석결과를 통해 즉시 피드백을 받을 수 있는 환경을 제공한다. 또한 교수자에게 많은 수의 학생들의 과제를 관리하고 교수자의 평가 기준에 의해 한꺼번에 자동으로 평가할 수 있는 환경을 제공하여 준다. 이러한 웹 기반 프로그래밍 교육 시스템은 웹을 이용한 프로그래밍 교육을 면대면 학습에 더욱 가깝게 만들어준다. 현재 웹 기반 프로그래밍 교육시스템은 K대학교 컴퓨터교육과 1학년 재학생들을 대상으로 한 C 프로그래밍 강좌에 사용되고 있다.
