Due to development of technology of information technology, PC communication and Internet have become a culture space of teenagers. Because Internet and PC communication are media in which teenagers have interests, they could be effectively used to counsel teenagers in that time they want. Moreover, cyber counseling will be suitable to new trend of current age with extension of counseling area. Accordingly, many researches on cyber counseling have proceeded in the area of teenagers counseling. While most researches for cyber counseling until present are about counseling methods ad the effects that teenagers utilize cyber counseling, there were no efforts that store counseling contents, analyze them using features and technologies of web and use them effectively to guide students. Therefore, we implemented a cyber counseling system that provides counseling information so that teacher may grasp students various interests and problems and thus helps to guide students.

In the recent rapidly changing IT environment, the amount of smart digital data is growing exponentially. As a result, in many areas, utilizing big data research and development services and related technologies is becoming more popular. In SMART learning, big data is used by students, teachers, parents, etc., from a perspective of the potential for many. In this paper, we describe big data and can utilize it to identify scenarios. Big data, obtained through customized learning services that can take advantage of the scheme, is proposed. To analyze educational big data processing technology for this purpose, we designed a system for big data processing. Education services offer the measures necessary to take advantage of educational big data. These measures were implemented on a test platform that operates in a cloud-based operations section for a pilot training program that can be applied properly. Teachers try using it directly, and in the interest of business and education, a survey was conducted based on enjoyment, the tools, and users' feelings (e.g., tense, worried, confident). We analyzed the results to lay the groundwork for educational use of big data.

This study is to develop a web-based career guidance system to be a help making a decision on one's occupation, which is important for a person's life. As career development education for higher grades of elementary school aims at providing basic knowledge necessary for career choice and forming a basic attitude toward occupation and values, it is desirable to carry out the guidance of a variety of occupations on the basis of personal interest and aptitude of individual students. Previously, however, most studies have remained at the level where simply test results are notified. Therefore, the study administered a career development test fit for higher grades of elementary school who are at the stage of potential career choice and developed a web-based career guidance system in which suitable occupation types are advised of based on the results. Beyond notifying test results, the developed career guidance system presents 3 excellent intelligences, rather than converting test results into scores. Thus, it is expected that the system will help students understand their areas of excellent intelligence, efficiently study related occupation types and duties, and learn to have awareness and make a better decision in relation to their career.
