The purpose of this study is to explore the necessity of technology commercialization aiding service from government-supported R&D institutions and find key success factors for market performance improvement of business ventures and SMEs. For this aim, we researched relevant theories and KICET(Korea Institute of Ceramic Engineering and Technology)'s "Ceramic Hidden Champion Supporting Project. As government-supported R&D institutions, KICET is not only providing its original main service which is technology advising and development, but also providing a full range of technology commercialization aiding service for business ventures including diagnosis, strategy planning, capital procurement, overseas marketing activity. Qualitative analysis based on relevant theories and meta-analysis framework suggest that such expansion of services is desirable for government-supported R&D institutions to increase market performance of business ventures and SMEs. To lead this business to success, we should develop effective management system and incentive system for external supporting companies and client companies. Also, coordination between team member's activities and budget procurement issue should be solved for further performance creation.

This study analyzed the learning objectives in the 2007 revised 10th grade Home Economics textbooks of 6 different publishing companies and the achievement standards developed by Ministry of Education, Science and Technology(2009). Two experienced coders performed initial analysis based on the 'revision of Bloom's taxonomy of educational objectives' and had subsequent conferences to reach an agreement on different results between coders. For knowledge dimension, the results show that the major types of learning objectives in the "Future Family Life" unit are mainly consisted of factual knowledge and procedural knowledge, where as those of "Family Life Culture" unit are consisted of factual knowledge and conceptual knowledge. The achievement standards in both "Future Family Life" and "Family Life Culture" units are solely in a factual knowledge major type. The sub-type of knowledge dimension of both learning objectives and achievement standards fall into 'a specific facts and knowledge component'. For cognitive process dimension, the results show that the leaning objectives are focused on 'understand' and 'analyze'. Those of achievement standards are 'analyse' in the "Future Family Life" unit and 'understand' in the "Family Life Culture" units. From the result of this study, we can conclude that both learning objectives and achievement standards do not adapt any meta-cognitive knowledge, higher order thinking, and cognitive process.

There have been numerous studies to develop eco-friendly concrete. The attempt to reduce the amount of cement usage is suggested as one of the solutions for eco-friendly concrete. To reduce the amount of cement usage, the pozzolan-reaction materials such as ground granulated blast furnace slag, fly ash, and meta kaolin are widely used as the mineral admixture. Hwangtoh which deposited broadly in Korea is a well known eco-friendly material and the activated Hwangtoh with pozzolan-reaction can be practically used as a mineral admixture of concrete. Meanwhile, PET fiber made of recycled PET bottle is a type of recycled material, which can be used to control micro cracks in concrete. But the study about concrete mixed with recycled PET fiber is insufficient and the research of Hwangtoh concrete mixed with PET fiber is urgently needed presently. In this study, experiment and analysis flexural behavior of Hwangtoh concrete blended with recycled PET fiber are carried out. The results are discussed in detail.

The purpose of this study is to investigate the characteristics of 'best practire' in mathematics and suggest some solutions to several problems emerging in mathematics classes of secondary schools. The study was carried out by using qualitative research methods such as class observations and in-depth interviews with six teachers. Based on the collected data, we could sort out the major patterns which characterize 'the good mathematics teaching' at schools in Korea. The common characteristics of best practice in mathematics are drawn out from the six cases. The common characteristics include revising the curriculum and text books, realistic mathematics education, using ICT and meta-cognition, introduction with motivation and interest, performance assessment and managing differentiated small group. Results implied that six teachers used a variety of instructional methods and strategies which is related with the common characteristics of good mathematics teaching. Also these teachers not only improved their own classroom practices but also participated in various professional community of mathematics education and shared their practical knowledge. In conclusion assorted efforts from the government and the school principals as well as the teachers are prerequisite for practicing and spreading good mathematics teaching across the classrooms.

Objectives : The aim of this meta-analysis study was to examine the relationship between cognitive anxiety and performance in closed loop skill sports. Methods : A comprehensive literature search was conducted using databases including Korean Information Service System, DBpia, Research Information Sharing Service, and National Assembly Library from 1980 to 2015. Search terms included 'Golf', 'Shooting', 'Archery', 'Anxiety', and 'Performance'. Standardized mean difference and 95% CI(confidence intervals) were calculated, and the heterogeneity of the studies was estimated using Q statistic. Results : Ten studies have satisfied the inclusion criteria. The main findings indicate that cognitive anxiety was significantly reverse correlated with performance in closed loop skill sports(r=-.198). The mean effect size for men(r=-.31) was significantly greater than that for women(r=-.05). Conclusions : Our results suggest that cognitive anxiety in closed loop skill sports is correlated with performance of athletes. Future study related to psychological aspects on athletes in sports is required in order to understand the specific evidence of relationship between anxiety and performance.

The purpose of this study is to develop the multi-modal interaction system. This system provides realistic and an immersive experience through multi-modal interaction. The system recognizes user behavior, intention, and attention, which overcomes the limitations of uni-modal interaction. The multi-modal interaction system is based upon gesture interaction methods, intuitive gesture interaction and attention evaluation technology. The gesture interaction methods were based on the sensors that were selected to analyze the accuracy of the 3-D gesture recognition technology using meta-analysis. The elements of intuitive gesture interaction were reflected through the results of experiments. The attention evaluation technology was developed by the physiological signal analysis. This system is divided into 3 modules; a motion cognitive system, an eye gaze detecting system, and a bio-reaction sensing system. The first module is the motion cognitive system which uses the accelerator sensor and flexible sensors to recognize hand and finger movements of the user. The second module is an eye gaze detecting system that detects pupil movements and reactions. The final module consists of a bio-reaction sensing system or attention evaluating system which tracks cardiovascular and skin temperature reactions. This study will be used for the development of realistic digital entertainment technology.

A body dysmorphic disorder refers to a state that individuals whose external appearance is normal consider their appearance to be meta-morphosed, or think there's something wrong with it, or view a trifle deficiency as severely disfigured. The purpose of this study was to examine the body dysmorphic disorder and depression of health-related and health-unrelated majors in an effort to compare the two groups. And it's also meant to investigate the relationship between body dysmorphic disorder and depression. The subjects in this study were 400 students at K college located in Gangwon Province. Out of them, the major of the 200 students belonged to the health science track, and that of the 200 students didn't. After a self-administered survey was conducted, the answer sheets from 319 respondents were analyzed. As a result, there appeared no differences between the health-related majors and the health-unrelated majors in body dysmorphic disorder. Although there might be various factors to concern body dysmorphic disorder, both groups found themselves to suffer from more depression when they had a severer body dysmorphic disorder, and their body dysmorphic disorder exerted a statistically significant influence on their self-rated depression. Therefore the careful management of body dysmorphic disorder was required, and it's especially needed to make research in that of health-related majors. At the same time, more detailed clinical research efforts should be directed into body dysmorphic disorder and self-rated depression.

In spite of the developing endovascular era, large (15-25 mm) and giant (>25 mm) wide-neck cerebral aneurysms remained technically challenging. Intracranial flow-diverting stents (FDS) were developed to address these challenges by targeting aneurysm hemodynamics to promote aneurysm occlusion. In 2011, the first FDS approved for use in the United States market. Shortly thereafter, the Pipeline of Uncoilable or Failed Aneurysms (PUFS) study was published demonstrating high efficacy and a similar complication profile to other intracranial stents. The initial FDA instructions for use (IFU) limited its use to patients 22 years old or older with wide-necked large or giant aneurysms of the internal carotid artery (ICA) from the petrous segment to superior hypophyseal artery/ophthalmic segment. Expanded IFU was tested in the Prospective Study on Embolization of Intracranial Aneurysms with PipelineTM Embolization Device (PREMIER) trial. With further post-approval clinical data, the United States FDA expanded the IFU to include patients with small or medium, wide-necked saccular or fusiform aneurysms from the petrous ICA to the ICA terminus. However, IFU is more restrictive in South Korea than in United States. Several systematic reviews and meta-analyses have sought to evaluate the overall efficacy of FDS for the treatment of cerebral aneurysms and consistently identify FDS as an effective technique for the treatment of aneurysms broadly with complication rates similar to other traditional techniques. A growing body of literature has demonstrated high efficacy of FDS for small aneurysms; distal artery aneurysms; non-saccular aneurysms posterior circulation aneurysms and complication rates similar to traditional techniques. In the short interval since the Pipeline Embolization Device was first introduced, FDS has been firmly entrenched as a powerful tool in the endovascular armamentarium. As new FDS are developed, established FDS are refined, and delivery systems are improved the uses for FDS will only expand further. Researchers continue to work to optimize the mechanical characteristics of the FDS themselves, aiming to optimize deploy ability and efficacy. With expanded use for small to medium aneurysms and posterior circulation aneurysms, FDS technology is firmly entrenched as a powerful tool to treat challenging aneurysms, both primarily and as an adjunct to coil embolization. With the aforementioned advances, the ease of FDS deployment will improve and complication rates will be further minimized. This will only further establish FDS deployment as a key strategy in the treatment of cerebral aneurysms.

The character is not dependent on an original story world any more. It is not limited to it's own story, but gets out and expands the other story with new character, background story, and event regardless of genre and media. The purpose of this study is to analyze why should this phenomenon happen from the media perspective and to build a character storytelling model through the specific examples. With the advent of the digital paradigm the storytelling model is emphasized character storytelling. Character is no longer limited to just one narrative and extended beyond the boundary narrative, media and genre. There are four background. First, disappearance of the big story with the advent of postmodernism and the emergnece of small story. Second, the emergence of fandom culture and charater's liberalization. Third, character as public goods with database. Fourth, changes in author's position. In fact, in the traditional narrative theory there has been discussion about the character all the time. But character storytelling meets transmedia storytelling, discussions were accelerated. The character was preceded by a narrative independent existence. Even if that character has occurred even while leading cause narrative. In this paper, we suggest two model as specific methodology to expand the story world fixed character. One is phychology transition, another is roll transition. This study get the value to build the new storytelling model with digital paradigm.
