  • Population-level learning has traditionally been used to provide an explanation for the underlying mechanism of industry change. But it has yet to examine the impact on strategic decisions such as market entry. This conceptual paper aims to provide an insight into how population-level learning affects entry likelihood by acting as a tool for interpreting population-level changes. We study this in the context of the fast-paced mobile gaming industry where population-level information is salient and develop a set of propositions with regard to the likelihood of entry.

  • 기존 인터페이스 연구는 전통적인 객관주의 인지 관점에 토대를 둔 수사적 메타포를 중심으로 연구되어 왔다. 그러나 미디어 환경의 변화로 인하여 기존의 연구 관점은 그 논리적 한계를 드러내고 있다. 본 연구에서는 체현 인지에 기반한 개념 메타포를 그 대안으로 제시하고 기존 인터페이스 환경에의 논리적 적합성을 고찰하였다. 고찰 결과 첫째, 체현 인지 관점은 총체적인 인지가 소통하는 공간 개념으로서의 인터페이스 관점을 제공해주는 이론이며, 체현 인지에 기반한 개념 메타포는 보다 구조화된 메타포 논리를 제공하여 복잡한 메타포 구조의 설명에 적합한 것으로 고찰되었다. 둘째, 그릇 이미지 스키마는 '안-밖-경계'의 기본적 구조 외에도 부차적 이미지 스키마를 제공하여 데스크탑 메타포를 설명하는 데 있어 기존 메타포에 비해 구체적이고 세부적인 구조를 제공해 준다. 셋째, 경로 이미지 스키마는 '출발점-경로-목적지'의 기본구조 외에도 부차적 이미지 스키마를 제공하여 기존 메타포가 가지는 논리 구조의 모호성과 혼란성을 해소하고 명확한 논리의 형성이 가능하다. 체현 인지에 기반한 개념 메타포는 인간의 물리적 경험을 그릇, 경로의 이미지 스키마로 표상함으로써 향후 다양한 미디어 환경의 인터페이스를 설명하는 이론적 근간이 될 것으로 기대된다.

  • 학생들의 개념 변화을 촉진하기 위하여 인지갈등상황을 제시하는 것이 필요하다는 주장이 여러 연구자들에 의하여 제기 되어왔다. 본 연구자들은 문헌 분석을 통하여 인지갈등을 유발할 수 있는 상황은 크게 세가지로 구분할 수 있었다. 이 연구의 목적은 이들 세가지 상황이 학생들의 과학개념 변화에 미치는 영향의 차이를 알아보는 것이었다. 연구 대상으로 참여한 학생은 경기도 소재의 인문 고등학교 2학년 72명이다. 갈등상황으로 체험을 제시할 때 직접 실험할 수 있는 인원의 한계성 때문에 한 반에 26명씩 선정하였다. 먼저 역학의 중요 개념에 대한 여섯 가지 문항을 이용하여 학생들의 사전 개념을 조사한 후, 갈등상황을 현상, 논리, 체험 등 3가지로 나누어 제시하고 수업을 한 다음 사후 검사를 실시하였다. 개념 변화의 지속성을 보기 위해서 1주일 후와 1개월 후에 같은 문항으로 검사를 실시하였다. 이 검사 결과를 바탕으로 각 문항별 응답 유형을 분석하여 학생들의 개념이 과학적으로 변화하였는지 조사하였다. 연구결과, 각 문항에서 과학적 개념으로 변화되는 학생 수는 체험제시 집단이 다른 두 집단에 비하여 많았으며 그 다음은 현상제시 집단이었다. 제시 특성별로 보면, 근운동을 통한 강한 체험이 가능한 문항에서는 체험제시의 효과가 높게 나타났으며 다른 문항들에서도 체험이나 시각적으로 명확하게 관찰이 가능한 정도에 따라 논리제시에 비하여 체험제시와 현상제시가 개념변화에 효과적인 것으로 나타났다. 따라서 학생들의 과학개념 변화를 위해서는 개념특성에 맞는 적절한 갈등상황을 제시해야 한다고 본다. 또한, 효과적인 개념 변화를 위해 갈등상황을 제시할 때, 모든 문항에 대해 현상이나 논리, 체험제시 중 어느 하나가 더 효과적이라고 구별하기보다는 문항의 종류와 갈등상황 제시의 특성, 학습자의 상태 등을 고려하여 제시해야 한다고 본다.

  • Acceleration of globalization in almost all industries, including fisheries, already had been a major paradigm of the age. And It has been weakened its meaning of geographical, cultural and economic boundaries between the nations. In particular, various changes in the fisheries environment have exceeded the area of problem for conventional single country is resolved. And if there is no cooperation with international cooperation other problems also almost nearly impossible to alleviate or solve. So it has emerged in this context, the concept of sustainable development and conceptual diagram of responsible fisheries. However, it has been passed about 20 years since the FAO documents published, there is little interest in it. In this study, analyzed the characteristics of the changes and its constitutive trends and contents of the FAO's responsible fisheries documents. And proposed both the need for analysis and research for the fisheries in an international context for the future and educational aspects. The results of this study show that FAO related documents are hardly to find that have been translated into Korean, in particular since the 2000s. And it is fairly skeptical whether there is a direct effective in fisheries in terms of language barriers. Therefore, the study on responsible fisheries much more important to develop the current status and future-oriented policy of international fisheries even in fisheries related education.

  • As the life expectancy of human beings gets longer and our society changes into highly competitive arena, the implementation of online adult learning is growing, and therefore the learners in self-regulated scaffolding learning environments is becoming an important topic. This study is to investigate the main effects of scaffolding and self-regulation and the interaction effect on discussion participation and comprehension in online learning environments. To do this, ninety-nine adults taking online learning courses with the open university in Korea were investigated. Adult learners were divided into one of the four groups (no scaffolding, conceptual, strategic, and conceptual and strategic scaffoldings). Regarding self-regulation, learners were divided into two groups (low and high self-regulated) based on the mean score of subjective report of self-regulated learning. The results are as follows : First, 'strategic scaffolding' is more effective than 'conceptual scaffolding' in discussion participation (F=2.772, p < .05) and comprehension test (F=7.156, p < .05). Second, high self-regulated learners more actively participate than low self-regulated learners in discussion (F=6.230, p < .05), and achieve higher scores (F=4.863, p < .05). Third, there is no interaction effect between scaffolding strategies and the level of self-regulation. The theoretical and practical implications of these findings are discussed.

  • Background: School is a primary health education setting for adolescents and the continuous support should be provided to renew school health education curriculum correspondent to cultural changes in Korean society. Objectives: This study was conducted to identify the principals and teachers' health education needs for their students and to analyze their conceptual map for health education curriculum at school. Methods: The sample size of the preliminary study was 321 of the teachers in elementary, middle, and high school, and that of the main study was 355 middle school principals and teachers over the country. The self-administered mailing survey was conducted to collect the available health education topics in the preliminary study, to identify the factor structure of the health education topics and to analyze the conceptual properties on health education with exploratory factor analysis and multidimensional scaling analysis in SPSS 12.0. Results: A total of 21 health education topics were collected from the preliminary survey and 31 topics were, comprehensively, generated for the main survey. In exploratory factor analysis, seven factors were generated in 1.0 or greater Eigen value standard. The seven factors were 'life health promotion,' 'disease prevention and drug control,' 'bulling and aggression prevention,' 'injury and sexual harassment prevention,' human-efficacy and regulation,' 'health protection for adolescence,' and 'alcohol and tobacco control.' The educational need scores were the highest in 'human-efficacy and regulation' and 'injury and sexual harassment prevention.' The two-dimensional cooperates were generated for the 31 health education topics and the two dimensional properties which divided the conceptual space were 'health-safety' for one and 'public/environmental-individual/personal' for the other. That is, middle school principals and teachers primarily, understand the health education curriculum in the sense of 'health vs. safety' and 'public/environmental vs individual/personal.' Conclusions: Health education curriculum and textbook should be developed based on teachers' needs and conditions for health education in school fields. The field-based health education programs or textbook would make more possible problem-solving health education for youth in real school fields.

  • The purpose of this study is to investigate the home-health-care workers licensing education course in Seoul, Korea. Based on the previous research, a conceptual model was suggested explaining the dynamics of perceived educational service quality (SERVQUAL), educational satisfaction and the occupational readiness. The data set for this study drawn from the 297 self-administered surveys were analyzed with the suggested conceptual model by utilizing AMOS program. The measurement models and conceptual model fit well with the collected data set. As results of this study, 5 domains of SERVQUAL were produced including accountability, trustiness, responsiveness, sympathy, and assurance. The results of structural modeling with latent variables confirmed that SERVQUAL were influenced perceived educational satisfaction as well as occupational readiness. Among the SERVQUAL domains, accountability, trustiness, responsiveness, and assurance had significant impacts on the educational satisfaction while accountability, trustiness and responsiveness had significant direct effects on the occupational readiness. The trustiness had significant indirect effects on the occupational readiness via the educational satisfaction. Hence, the educational satisfaction had the significant impacts on the occupational readiness. Based on the findings of this study, we suggest to intense the educational program or curricular focusing on the SERVQUAL elements. Those changes will enhance self-confidence among the prospective home-health-care workers as well as public trustiness on the national long-term care program.

  • This study examines the conceptual characteristics of fantasy movies. It also studies the process of socio-cultural changes of the mythical images such as heroes, goddesses and the devil that have often become the centre of fantasy movie characters. This study further examines the features of each character that correspond to specific mythical images. The purpose of this research is to suggest the conceptual and aesthetic characteristics of fantasy reflected in the characters and the costumes of fantasy movies, which were released since the year 2000. The followings are the results of the research: The conceptual characteristics of fantasy reflected in the characters and the costumes of fantasy movies are summarized as representation of reality, allegory and symbols, horror, desire, deconstruction and metamorphosis, otherness and counter-cultural sentiments. The aesthetic characteristics of the costumes of fantasy movies are defined as typicality and symbolism, grotesqueness, sensuality, hybridization, and otherness. These characteristics are very interconnected. The costumes of heroic characters appearing in fantasy movies show strong side of standard while the costumes of the evil characters revealed the limit of dualistic point of worldview centered on West. Heroic characters show realistic and human side that reflects the ethos of the time. Negative characters such as the devil or witches, which were created in human imagination and emotion, become the dynamic force of fantasy movies through their deviant actions. Their clothes, with variety and hybridization, become the source of creativity expected in present society.
