This study aims to improve the quality of classes by analyzing the role and learning achievement of instructors in programming subjects for non-major students. In order to improve the quality of university education, universities provide various programs to strengthen the teaching capacity of instructors. Ultimately, in order to improve the quality of classes, instructors increase student participation in classes, respond sincerely to students' inquiries, and provide feedback that can assist students in various situations that occur during class and learning, thereby improving class satisfaction and achievement. should try to improve. In this paper, based on the teaching method, learning achievement, and teacher role satisfaction survey conducted in the liberal arts programming course of K University, we study the influence of the teacher's role on the quality improvement of the class. Examine the relationship with satisfaction.

Programming education plays a very effective role in comprehensively learning problem analysis ability, logical thinking ability, procedural problem solving method, and imaginary problem solving method. Until recently, however, it is not applied to the elementary and the middle school in Korea, which is very different from the other IT centerd countries such as the U.S., etc., where coding class is actively implemented. Fortunately, Korean government recognized this reality and decided to implement programming education as a regular subject in the elementary school from 2017. In this situation, many researchers' programming education model research is urgently required for the students to learn in the elementary and the middle school. This research developed and suggested 17 sessions of programing education model connected with scratch language and sensor board, which is hardware, to be applied to the class of the 5th and 6th graders. As the result of implementing the joint class of 5th and 6th graders during the after-school class based on programming education process suggested to verify the suitability for elementary school programing education, satisfactory achievement was attained by the assessed students. The researcher plans to develop an optimum model proper for the elementary school students' intellectual capacity by more improving programming education model.

As the importance of technology in education has increased, TPACK research has been actively conducted to promote the use of technology in class. However, due to the functional limitations of technology, the pre-service teacher had difficulty in using technology in class. Therefore, in this study, we have been studying the introduction of the programming language as a technology tool of TPACK. Using design-based research as a research method, we repeatedly developed an educational program, applied to pre-service teachers, and evaluated the effectiveness of the program. In the first study, pre-service teachers had difficulties in programming learning. To solve this problem, programming-based instruction and curriculum analysis were supplemented by educational programs. In the second study, pre-service teachers felt difficulty in using programming in teaching-learning, thus improving instruction design and reflection. The third study enhanced the programming development environment search to supplement programming learning and utilization.

21C future learners are required to have creative thinking and problem-solving capability to address an issue wisely by integrating and applying knowledge and functions. The robot education that has recently been studied in primary and secondary schools was reported to be effective in satisfying the requirements. The robot education varies ranging from the existing after-school education to an integrated approach used for regular curriculums, and has actively been studied. Nevertheless, aside from positive study results, any studies on the environment where primary school students can learn robot and programming knowledge more friendly is still insufficient. Therefore, this study was intended to give students a robot class with the use of storytelling friendly to students in order for primary school students to learn robot and programming knowledge with ease. The study result showed that acquirement of programming knowledge was improved, and that the students had a positive learning attitude. In addition, it was found that the storytelling of the robot class helped provide the entire learning context and continuous learning motivation for the students.

The standard Java class library does not support the platform-dependent features needed by the application. Therefore, the Java application including the platform -dependent features must supplement the required features by invoking native functions using JNI. The native language programmer has to explicitly specify how to connect to various Java objects and later to disconnect from them. In this paper, I suggest a way to avoid these annoying works. The native method in the pure java class can not contain a native code block. By providing a native code block for the native method, it is possible for programmer to write a native code without being aware of JNI. To achieve this, I introduced the native class that is a java class on the native environment, and made it possible to interchange data by placing an arbitrator between the java class and the native class.

This paper presents a linear programming based algorithm for pattern classification. Pattern classification is being considered to be critical in the area of artificial intelligence and business applications. Previous methods employing linear programming have been aimed at two-group discrimination with one or more linear discriminant functions. Therefore, there are some limitations in applying available linear programming formulations directly to general multi-class classification problems. The algorithm proposed in this manuscript is based on quadratic or polynomial discriminant functions, which allow more flexibility in covering the class regions in the N-dimensional space. The proposed algorithm is compared with other competitive methods of pattern classification in experimental results and is shown to be competitive enough for a general purpose classifier.

A post-processing program based on the OOP(Object-Oriented Programming) concept has been developed for flow visualization of the flow analysis code(PowerCFD) using unstructured cell-centered method. User-friendly GUI(GTaphic User Interface) has been built on the base of MFC(Microsoft Foundation Class). The program is organized as modules by classes including those based on VTK(Visualization ToolKit)-library, and these classes are made to function through inheritance and cooperation which is an important and valuable OOP concept. The major functions of this post-processor program are introduced and demonstrated, which include mesh plot, contour plot, vector plot, surface plots, cut plot, clip plot, xy-plot and streamline plot as well as view manipulation (translation, rotation, scaling etc).

This paper deals with a special class of inverse problems in discrete structural plasticity involving the identification of elastic limits and hardening moduli on the basis of information on displacements. The governing equations lead naturally to a special and challenging optimization problem known as a Mathematical Program with Equilibrium Constraints (MPEC), a key feature of which is the orthogonality of two sign-constrained vectors or so-called "complementarity" condition. We investigate numerically the application of two simple algorithms, both based on the use of the general purpose nonlinear programming code CONOPT accessed via the GAMS modeling language, for solving the suitably reformulated problem. Application is illustrated by means of two numerical examples.

A new PC-based Engine Control system (ECS) is developed using an object oriented programming method. This system provides more convenient environment for engine tests, easier user interface and extended functions. A Windows-based ECS software is developed with class, and the class structure is built on encapsulation and abstraction. The closed-loop engine control scheme can be easily constructed by using dynamic link library and multitasking. This means that a user can perform desired experiments without clear knowledge of the hardware structure of the ECS. Also this system allows a user to individually control the ignition and fuel injection for each cylinder in a simple manner such as through a keyboard/mouse or in a real-time operation from a closed-loop control program.
