구직자들은 극도로 어려운 취업난을 겪고 있고 기업들은 인력난을 호소하고 있다. 이 상반된 현상에 대한 견해들은 부분적으로 타당성을 가진다. 하지만 구직자와 구인자 간의 근본적인 차이는 존재한다. 그것은 구인자로서는 아무리 구직자가 많아도 찾고자하는 인력이 없다는 것과 구직자는 자신이 원하는 기업이 아니면 취업자체를 꺼리는 현상이 나타나고 있다. 하지만 이러한 현상은 젊은 고학력자들의 실업화를 불러왔다. 그러나 우리나라의 인력은 세계에 내놓아도 경쟁력이 있는 고급두뇌들이다. 특히 정보통신 분야는 우리나라가 경쟁력을 가진 분야이며 해외에서는 정보통신관련 인력의 수요가 끊임없이 발생하고 있다는 것이다. 포화상태에 있는 국내 정보통신 인력들의 해외진출 또한 국가경제 측면에서 제고할 만한 사항이다. 이에 해외 외국의 정보통신 분야의 인력 수급현황을 살펴보고 국내 인력의 해외진출에 대해 살펴보고자 한다.

In this study, we developed a learning progression for the structure of the solar system using multi-tier supply form items and validated its appropriateness. To this end, by applying Wilson's (2005) construct modeling approach, we set up 'solar system components,' 'size and distance pattern of solar system planets,' and 'solar system modeling' as the progress variables of the learning progression and constructed multi-tier supply form items for each of these variables. The items were applied to 150 fifth graders before and after the classes that dealt with the 'solar system and star' unit. To describe the results of the assessment, the students' responses to each item were categorized into five levels. By analyzing the Wright map that was created by applying the partial credit Rasch model, we validated the appropriateness of the learning progression based on the students' responses. In addition, the validity of the hypothetical pathway that was established in the learning progression was verified by tracking changes in the developmental level of students before and after the classes. The results of the research are as follows. The bottom-up research method that used multi-tier supply form items was able to elaborately set the empirical learning progression for the conceptualization of the structure of the solar system that is taught in elementary school. In addition, the validity of the learning progression was high, and the development of students was found to change with the learning progression.

Recently it has been claimed that character education should be applied not only in ethics but also in other disciplines including science education. With several attempts at character education in previous research on science education, the examination of its requisite and components is needed. This research investigates the necessity and elements of character education to be improved upon in science classes through questionnaires and focus interviews of experts in the field of science education such as secondary school teachers, professors, and researchers. They recognize that character education should be adopted in science education with three backgrounds: scientist activities, the field of secondary school, and inquiry education. Based on moral education and citizenship, elements of character education in science class are comprised of four essential character elements including honesty, sympathy, tolerance, and self-esteem, and seven practical character elements that are divided into personal qualities: sincerity, responsibility, and self-control and social qualities: consideration, openness, communication, and cooperation. Their validity and importance are accepted by experts.

The purpose of this study was to verify the construct validity of self-evaluated writing scale for students with disabilities who had difficulties in writing. After interpreting the Here's How I Write scale developed by Goldstand et al. (2013), we administered Delphi survey to 40 special education professionals, calculated the content validity ratio and decided the final scale of 21 questions applicable to Korea. Additionally, we carried out the scale to 350 disabled and normal students for testing construct validity. The main results are as follows: For both students with disabilities and without disabilities, the overall internal consistency of scale are higher than .89 and the internal consistency of factors of scale are higher than .66. The confirmative factor analysis using AMOS 21.0 and SPSS 21.0 to verify construct validity showed fit index at relatively satisfactory level for students with disabilities and without disabilities. Furthermore, while there were relatively strong convergent validity and discriminant validity in the sub-factors of scale for students without disabilities, the level of convergent validity and discriminant validity were relatively lower for students with disabilities.

There were 540 participants who were students majored in security martial arts, workers for security and specialists of practical and theoretical security martial arts for this study. The exploratory and confirmatory factor analysis were carried out using the selecting data through literature reviews in the level of the factor-extraction about the spiritual characteristics. The specialists' survey was conducted on the relative status among factors using the spiritual concept structure based on the studied above. Selected data was calculated with SPSS 18.0 for windows, AMOS 5.0, and Expert Choice 2000 software. The conclusion can be made through those process above. First, 4 general factors and 20 detailed factors were found as the result of the factor exploration related to the spiritual characteristics of the security martial arts. The result which was verified on Construction validity of searched factors had stable figures on every standard. In other words, the participants for survey on this study "Spiritual characteristic concepts of the security martial arts" can be evaluated it is valid. The general factors of security martial arts' spirit were conceptualized with Psychological spirit, ethical spirit, martial art spirit, practical spirit through the naming process on the general factors of the security martial arts' spiritual characteristic concepts. The detailed factors of security martial arts' spirit were concentration, self-confidence, self-management, immersion, self-esteem in psychological spirit and sacrifice, justice, royalty, peace, sense of duty in ethical spirit and courtesy, toughness, defense, balance of mind and body, bravery in martial arts and responsibility, cooperation, modesty, determination, professionalism in practical spirit of security martial arts. That is, the conceptualization of security martial arts' spirit was verified that it had validity.

The purpose of this study is to develop a survey tool of scientific character for elementary student which connects science education and character education effectively by figuring out traits of elementary students' character being presented in teaching and learning context of elementary school science. For this, we adapted the theocratical model from the previous research which defined scientific character as the competencies being able to practice in concrete teaching and learning context of science. Based on this model, we developed the survey tool as 'Scientific Character Inventory for Elementary Student' to assess elementary students' scientific character as the competences to practice the virtues being pursued in the context of elementary school science and verified its reliability and validity. As a result of an exploratory and confirmatory factor analysis, we confirmed all the items could be summarized into 28 items and eight constructs such as scientific problem-solving, self-management, self-reflection, communication, interpersonal skill, community participation, global citizenship, and environmental ethics awareness. We found that minimum reliability coefficient of constructs was over than 0.5 and reliability coefficient of the total items was 0.878. And also, there was modest relationship between each construct and the total score of scientific character. These results show that the developed survey tool can be useful in evaluating the effectiveness of science character education. This study is meaningful in that it systematically reveals constructs of scientific character which can be raised in concrete context of science teaching and learning so as to suggest the survey tool to assess this.
