We are taking advantage of the information and communications technology in every field of life at the moment. At this point of view, it is necessary to verify how the information technology performing properly in the education field. This paper is to analyze it and point out the problems in the significant programing study and map out the utilizing of Robot programing education based on the computer principle education. Therefore it is contributed to raise ingenuity, ability to think, problem-solving ability for the students as replacing old programing education with Robot programing education.

The conception of the computer education should be paid attention to use, as it has meaning of the education using the computer and the education learning the computer. As a notion of the latter, the computer education points at survey of calculation and study which is related programing. Especially study of programing demands various understandings of external fields in programing like operating system and knowledge of hardware with complex courses like coding, compiling, debugging. Existing programming has set importance on mechanical memorizing and using programing grammar so that it has not been suitable for cultivating logical thoughts. So this paper intends to analyze simple game sources coded by C which is based of programing language to develop a fundamental insight.

As UNFCC(United Nations Framework Convention on Climate Change) is enhanced, Korea will perform a CO2 reduction duty. The CO2 reduction duty will effect Korea power system because coal and oil thermal generations emit large CO2 form about 46% of total CO2 emission. Moreover various alternatives should be designed to comply with CO2 reduction duty. In this paper, we analysis resource planning considering CO2 emission constraints and emission trading. And we analysis resource planning under using LP(Linear Programing) and MIP(Mixed Integer Programing).

This research targeted some content of curriculum of the 2nd semester of the 6th grade to search a method for algorithm realization and digital programing of the regular curriculum. This research analyzed the effect of programing study on the elementary school students by analyzing the survey and teachers' evaluation result after programing utilized with some curriculum along with scratch and sensor board after conducting a class on 6th graders. As the result, interest and participation of programing study appeared higher, respectively 9.37% and 7.53% when sensor board, the hardware, rather than merely utilizing scratch while programing study. Also, understanding of class displayed 7.53% higher. Achievement evaluation that evaluated effective completion of programing, also, was analyzed effective, since it is available for a wide algorithm realization.

Excessive cognitive burdens caused by learning grammar should be reduced to cultivate high-level thinking skills in students through programing education. To this end, various educational programing languages have been developed. In recent years, block-based App Inventor that can used in real life have been introduced. This study intends to suggest an educational environment in which programing can be utilized as a leading problem solving tool by designing and producing an app that can be easily used by students in their real life. In particular, given the developmental phase of elementary school students, specific operational activities are important. For this reason, an App Inventor that can be proposed to enable dynamic interactions with the real world based on various smartphone sensors during the process of programing has significance as an educational programing language for elementary school students. In this regard, this study designed App Inventor programing education for elementary school students, which can be used in their daily life. The results of applying the education in fifth graders showed its positive effects on learning programing. LT collaborative learning where the students cooperated with each other, the theme of learning, which enables the utilization of various smartphone sensors in real life, and the app inventor may have generated and sustained the students' interest and attention.

During the last 25 years, independent TV production programing quota policy has been actively evaluated in various aspects except in the field of production personnel. This study focuses on production personnel who has been neglected among the debate of independent TV production programing policy. Especially, this study tries to explore the effect that the policy has brought to production personnel's motivation. After in-depth interviews with 4 professionals and 6 media major senior college students, this study finds that both broadcasting and independent company professionals evaluated the policy performance in negative way. They insist the policy constricts their motivation for production. College students agreed they become unwilling to entering the production filed. The policy should be reconsidered and turn to positive incentives and rewards to motivate production personnel.

This paper proposes several methods for effective teaching of programing language(especially C). The programing languages are very important and basic subjects in the Department of Computer Engineering and Science. Many students have some difficulty in learning the programming languages. So, we will suggest several effective methods for effective teaching of programming languages. First, in order to understand the programming language effectively, we need to teach some basic computer architecture and operation principles of computer program to students. Second, it is better to teach many example-based programing skills instead of conventional grammar teaching. Third, if we teach the memory status(memory allocation/release) during the program operation, it will be much better to understand the pointer variables and memory problems. Fourth, let's improve the programming skills through effective homework assignments and experiments. Fifth, let students be guided so that they do programing by themselves. Finally, we can maximize the programming skill through the final termproject.

In this paper, it is practically difficult to obtain programming language education without having an algorithmic thinking ability, computing thinking ability, and problem solving ability of students with relatively low basic education. The results showed that students who took program language education in parallel with the EPL(Educational Programing Language), Scratch, compared to without using Scratch found to be helpful in improving their programming amd computing thinking ability, and problem-solving abilities as well as their satisfaction. This not only gave students confidence in their hard-thinking programming practices, but also helped prevent them from falling out of the middle.

A battery is the primary energy source device presently used in hybrid electric vehicle. It can store much energy, but cannot provide enough current without inefficient units. However, an ultracapcitor can provide much current, but cannot store much energy. It will have better fuel economy by combining the two energy sources in parallel. The purpose of this paper is making the simulator of the two HEV systems. The one has only battery, the other have battery and ultarcapacitor in parallel. To compare the fuel economy, dynamic programing was used for optimization and prius was used for HEV model.

Winkler (1990, 2001), Sitter and Skinner (1994), Wilson and Sitter (2002) present a method which applies linear programing to designing surveys with multi-way stratification, primarily in situation where the desired sample size is less than or only slightly larger than the total number of stratification cells. A comparison is made with existing methods both by illustrating the sampling schemes generated for specific examples, by evaluating sample mean, variance estimation, and mean squared errors, and by simulating sample mean for all methods. The computations required can, however, increase rapidly as the number of cells in the multi-way classification increase. In this article their approach is applied to multi-way stratification using real data.
