  • In order to establish an air force e-learning system, we analysed previous researches on air force education systems and conducted a survey on 3,597 air force trainees. Most of trainees have little experience on e-learning and do not understand it. But if they were given an opportunity, they would like to take a e-learning course. They had a lot of requests about function improvement for learning management systems, preferred individual education rather than collective education, and did not wanted to take an e-learning class at a computer laboratory. In this study, we found four elements that need to establish e-learning system for air force. They are content, trainer, trainee and service. Also, we suggested improvement plans for each elements.

  • The purpose of the study is to review the research trends of human development and family studies which published in the Journal of the Korean Home Economics Education for last 20 years. A total of 93 studies were analyzed in the area of nature and philosophy of Home Economic Education, curriculum, teaching-learning method and human development and family studies. Research topics mainly examined in the area of curriculum development, application of teaching methods, psychological and school adjustment of the adolescent and family relations. Reviews in methodological issues result in the heavy usage of survey method with self-administered questionnaires, convenient sampling and descriptive studies. Although research on human development and family studies in Home Economic Education has increased in quantity, there are greater needs to develop studios with representative subjects, various research methods, teaching - learning methods, and teaching materials to capture the rich complexity of individual development and family life. Limitations on previous studios and implications for future studies were also discussed.

  • This study aimed to investigate beginner-level learners' use of translators in L2 writing, and shed light on its validity in writing performance through their responses on the necessity, reliability and limitation of machine translation. 117 university students from beginner-level L2 writing classes participated in the survey. Additionally, 11 of them were interviewed about their answers. The survey and interview data revealed varying viewpoints such as reliability and effects as well as reasons for choosing translator-assisted writing. The vast majority(76.1%) used web-based machine translators for their writing activities, and employed various strategies to help their insufficient L2 skills and to increase their motivation and confidence. On the other hand, they exhibited its detrimental effects including it could lead to plagiarism, and interfere with the learning process unless they post-edited the given translation. However, translators were viewed as a new, efficient, and valid educational tool for effective and successful L2 writing.

  • Analyzing research schools' reports on school library activities, this paper identifies the characteristics and problems of library assisted instruction (LAI), and proposes areas and ways for improvement. Twenty three reports of secondary schools in Edunet were analyzed and their content were categorized into 13 educational activities. Most frequently implemented activities were collection development, reading programs, LAI, and Digital Library System (DLS). The verified positive impact of LAI include enhanced motivation for reading and improved ability for self-directed learning. Areas for improvement include LAI's excessive dependence on DLS and reading activities, insufficient time and library materials which hindered students' information activities. In order for LAI to be more effective in enhancing self-directed learning ability, it is suggested to connect LAI to specific educational experiences and develop customized and detailed content.

  • The purpose of this study is to compare with three juvenile delinquency theories on adolescents' status offenses including Hirschi's social bonding theory, Agnew's general strain theory, and Akers' social learning theory. The data derived from a sample of 2,337 middle school students taken from National Youth Policy Institute in 2011-2012. Multiple OLS regression analysis revealed that variables from social learning theory were strongly supported as an explanation for adolescents' status offenses, while variables from general strain theory were not supported. The social learning model explained 12.0% of the variance in adolescents' status offenses. However, general strain variables explained 2.6% of the variance in the dependant variable and 6.2% of the variance in adolescents' status offenses were explained by the social bonding variables. The present research made important contributions the further utilization of social learning in investigating many of the damaging forms of social deviance which exist in our society.

  • Unlike behaviors that are generally known, information regarding unspecific behaviors is insufficient. For an education or guidance regarding the unspecific behaviors, collection and management of data regarding the unspecific behaviors of special-needs students are needed. In this paper, a consultation management model based on behavior classification of special-needs students using machine learning is proposed. It collects data by photographing the behavior of special students in real time, analyzes the behavior pattern, composes a data set, and trains it in the suggestion system. It is possible to improve the accuracy by comparing the behavior of special students photographed later into the suggestion system and analyzing the results by comparing it with the existing data again. The test has been performed by arbitrarily applying unspecific behaviors that are not stored in the database, and the forecast model has accurately classified and grouped the input data. Also, it has been verified that it is possible to accurately distinguish and classify the behaviors through the feature data of the behaviors even if there are some errors in the input process.

  • The purpose of this study was to explore the lived experiences of university students who were placed under academic probation. A qualitative research design was used to understand the experiences of students. The data were collected using individual in-depth interviews with 4 students who had experiences of low academic achievements at least once during 5 semesters. Low self esteem was the main issue in this study and inner struggles were identified within 4 themes: Outstanding students controlled by helpers; A costume play as a outstanding student; Realize that I am a under academic achiever; Realize who I am and what I have to do. This study identified that low academic achievement brings to low self esteem seriously, however, human being has strong resilience in the traumatic circumstances. Thus, it is absolutely necessary devoting efforts to develop suitable student supporting programs in the way of inner and outer network systems.

  • This study aimed to explore the constructs of the characteristics of at-risk learners with diverse educational needs in the blind spots of education, in order to understand them comprehensively and detect them early in schools. Participants were 156 elementary, middle, and high school teachers who filled out a semi-structured questionnaire consisting of open questions about their implicit knowledge of the characteristics of at-risk learners in the blind spots of education. Qualitative data were analyzed using a modified consensual qualitative research method. The main findings of this study are as follows. First, five domains and 16 categories were derived as the main constructs of the characteristics of learners in the blind spots of education. Second, the most listed of the five domains was the "domain of low learning and cognition," whereas the least listed domain was the "everyday life domain." Finally, deficiencies of interpersonal skills and interactive communications and categories related to family structure and functions frequently appeared among the 16 categories. Based on these results, implications and potentials for follow-up studies were further discussed.
