Social Network Service (SNS) has been played an important role in the life with the expansion of the modern technology in the cellular communication. More knowledge and understanding should be inevitable even if companies have taken advantage of SNS through word of mouth as one of the new paradigm. In most cases the crucial benefit or peculiarity of SNS has been overlooked because only general aspects of SNS have been applied in the online situation. As a result of this, same paradigm has been considered in reality as SNS was just used one of the marketing tools. However, essential aspects of SNS were investigated to see the relation of usage intention and word of mouth in this study. The hypothesis of the effect of continuous intention of the usage, trust and word of mouth was made and reviewed statistically. The statistical analysis showed there was significant among relationship, context, perceived service quality and continuous intention of the usage. In addition to that, self-expression, relationship, perceived service quality and trust were significant. Finally the continuous intention of the usage and word of mouth was significant as well. Based on this study, SNS provided by the companies could be effective to the customers in terms of word of mouth while different trend was shown in terms of trust.

Patient safety remains one of the most important health care issues in Korea. To improve patient safety, we have introduced concepts from the field of safety science such as the Swiss cheese model, and adopted several methodologies previously used in other industries, including incident reporting systems, root cause analysis, and failure mode and effects analysis. This approach has enabled substantial progress in patient safety to be made through undertaking patient safety improvement activities in hospitals that are systems-based, rather than individual-based. However, these methods have the shared limitation of focusing on negative consequences of patient safety. Therefore, the paradigm shift from Safety I to Safety-II in safety science becomes the focus of our discussion. We believe that Safety-II will complement, rather than replace, Safety-I in the discipline of patient safety. In order to continuously advance patient safety practices in Korea, it is necessary that Korea keeps abreast of the recent global trends and development in safety science. In addition, more focus should be placed on testing the feasibility of new patient safety approaches in real-world situations.

e-Learning으로 대변되는 교육의 변화는 교육환경의 기술적인 측면뿐만 아니라 패러다임 자체를 바꾸어 놓고 있다. e-Learning 환경에서의 사용자는 시스템 사용자뿐만 아니라 학습자의 역할을 동시에 가지고 있기 때문에 이런 복잡한 현상을 설명하기 위해서는 보다 포괄적인 시각이 필요하다고 판단된다. 본 연구에서는 포괄적인 시각을 연구하기에 앞서 학습자의 동기 유발에 초점을 두고 학습 성과를 향상시킬 수 있는 방안을 플로우 이론을 이용하여 제시하고자 한다. 연구 결과 첫째, 플로우의 구성 요소인 내재된 흥미와 주의집중은 종속 변수인 학습 성과에 유의적인 영향을 미치고 있으며, 특히 내재된 흥미가 주의집중보다 더 중요한 요인으로 밝혀졌다. 둘째, 내재된 흥미에 영향을 미치는 요인은 정보 품질과 숙련도로 나타났으며, 셋째, 주의집중에 영향을 미치는 요인은 인지된 사용용이성, 숙련도, 컴퓨터 자기효능감으로 나타났다.

상품 및 시장의 복잡성으로 인하여 소비자들은 마케팅 대상에 대하여 역설적인 태도를 가지는 현상이 증대하게 되었는데, 이런 역설적인 태도들은 소비자와 상품간의 관계에 중요한 영향을 미치게 된다. 본 연구에서는 심층 면접, 근거 이론 등을 활용하여 최근 그 중요성이 강조되고 있는 농식품을 중심으로 이런 역설적 현상들을 발견하고 소비자의 대응 행동 양식을 이해하고자 하였다. 연구 결과에 의하면 사전의 기대나 소비 경험이 역설을 발생시키는 요인이 되며, 이로 인하여 가격, 유통, 상품, 촉진 및 소비와 관련한 역설적인 품질 경험이 발생하게 됨을 알 수 있었다. 발생된 경험은 인구통계학적 특성의 차이나 기타 기호, 위험 지각 등 중재적 조건의 정도에 따라 차이는 있지만 소비자들에게 품질 역설과 관련된 상호작용이나 커뮤니케이션을 유발하게 되고, 결과적으로 소비자들이 이런 역설적 상황에 보다 효율적으로 대응할 수 있도록 구매 최소화, 잉여분 처분, 참여, 품질기대 조정, 품질기준 재정립, 품질정보원 활용 등 다양한 대응 전략들을 촉진하게 된다.

One of the recent and most significant technical properties can be expressed as "digital convergence," which is helping lead the technical paradigm into a ubiquitous environment. As an initial trial of realizing a ubiquitous environment, the convergence between broadcasting and telecommunication fields is now on the way, where it is required to develop a scalable video coding scheme for one-source and multi-use media. Traditional scalable video coding schemes have, however, limitations for higher stable picture quality especially on the region of interest. Therefore, this paper introduces an adaptive scanning method especially designed for a higher regional-stable picture quality under a ubiquitous video coding environment, which can improve the subjective quality of the decoded video by most-preferentially encoding, transmitting, and decoding the top-priority image information of the region of interest. Thus, the video can be more clearly visible to users. From various simulation results, the proposed scanning method in this paper can achieve an improved subjective picture quality far better than the widely used raster scan order in conventional video coding schemes, especially on the region of interest, and without a significant loss of quality in the left-over region.

This study involves an experiment for the cognitive experiment design and the human reliability in software engineering. Its overall objectives are to analyze common-cause human domain error and reliability in human-software interaction. A laboratory study was performed to analyze software engineers' task behavior in software production and to identify software design factors contributing to the effects in common cause failure redundancy. Common-cause model and its function were developed, then the main experiment using programming experts was conducted in order to define a new cognitive paradigm, in the aspects of identification, pattern recognition, and behavior domain for human reliability and quality control in software development. The results and analytical procedures developed in this research can be applied to reliability improvement and cost reduction in software development for many applications. Results are also expected to provide guidelines for software engineering quality control and for more effective design of human-software interface system.

About 20 years have passed since Systems Engineering(SE) was introduced in Korea. KCOSE(Korean Council On Systems Engineering) and KOSSE(The Korean Society of Systems Engineering) were established during that period and Korean SE community has increased quantitatively. But We can not answer "Yes!" for the questions "Did Korean SE community increase qualitatively? and How about SE education or training?" Many participants at SE lecture classes said that they were not able to understand SE concept. I analyzed current SE lecture materials and then proposed new model of SE concept lecture for SE novices. The new model consists of Vee diagram, life cycle model, PMTE paradigm, technical review, SE sample and definition of SE. I expect that the proposed model will contribute to upgrade a quality of domestic SE education.

The emergence of systems biology in the 21st century is changing the paradigm of biomedical research. Whereas the reductionist approaches focus on components rather than time or contexts, systems biology focus more on interrelationships, dynamics, and contexts. The key ideas of the systems biology shares much with the philosophy of Korean Medicine(KM) and therefore, the paradigm shift is shedding light on understanding the mechanism of action of KM at system level. In this article, I provide a guide to learning systems biology for KM researchers using online learning resources. Thanks to the recent development of MOOC(massive open online courses) and other online learning platforms, learners can access to plenty of high-quality resources from top-tier universities in the world. I expect this guide help researchers to employ systems biology methods into their KM researches, and will lead to the development of future curricula for training "bi-lingual" experts, KM and computational approaches.

The present study is to investigate the middle school students' worldview and consciousness about the environment. To conduct this study, 605 students from the two middle schools of Daegu metropolitan area, seventh grade, were measured using a modified version of New Environmental Paradigm (NEP) instrument and qustionnaire of environmental consciousness. The results are as follows: First, a majority of middle school students held an ecological environmental worldview. They also had a similar environmental worldview to education experience on environment-related to subjects. The strongest area of agreement with the NEP were in the "Negative results of growth and technology." The weakest area of agreement with the NEP were in the "Quality of life" dimension with only 44.9 percent agreement across that dimension's four statements. Second, the middle school students are sensible of consciousness in environmental problems. They pointed out that air pollution and noise are the most as sever problems in country and local area, respectively. Finally, the subjects who showed the higher environmental worldview had a higher environmental consciousness and better attitudes related to environmental problems.
