As an increasing amount of Korean animation is being produced for Hollywood films, and/or winning prizes at international animation festivals, Korean animation is proving its growth potential and competitive power. In order for such domestic cartoons and animation to stably develop and maintain firm competitive power in international markets, cartoonists and animators need programs to support their creations, and locations where they can create their works. They also keenly demand the development of various programs and support policies that fit Korea's situation. In addition, if independently produced cartoons and animations have stable locations where they can be shown and commercialized, they can receive public benefits, beyond short-term commercial effects. Based on these views, this study sheds light on the concept, formation, and vitalization of a creation space and resident program, through the intentions of a studio where young and would-be artists create their works. In addition, this study has a significant meaning in that it offers a more effective and positive policy direction, as well as more opportunities to re-educate artists. As a result, it is expected that this study will contribute toward recovering the identity of cartoons and animation, which have been recognized as commercial genres, and to firm up their competitive power in international markets. It also demonstrates that these creation spaces, beyond the simple logic in which a creation space only motivates an artist's desire to create, will help in developing Korean cartoons and animation through cultural and personal exchanges with artists of foreign countries, and through an understanding of other cultures, offer communication programs to connect Seoul and other local communities, and establish the cultural identity of local communities where such creation facilities are located. In this way, the public can more easily understand and access cartoons and animation in their daily lives through these creation spaces.

This study aims to reproduce of Anuisamdong's landscape structure and improve the value of Scenic site. It was extract main spot from Geography book published by government in the 19th Century. And analyzed landscape architecture of Dongcheon. Extract main spot from Geography book published by government. Consequently, Hwarim-dong main spot 6 places, Simjin-dong main spot 9 places, and Wonhak-dong main spot 25 places were identified. Hwarim-dong's main spot was divided into 3 places of pavilion and scenery, respectively. Simjin-Dong's main spots was all that natural elements as a scenery. Wonhak-dong's main spot was the most elements of the Anuisamdong in geography book published by government. Hwarim-dong was pavilion-based scenery area complex, Simjin-dong was continues scenery spot along the valley, and Wonhak-dong was hybrid distribution that landscape structure. Each dongcheon in Anuisamdong was created a separate area through isolated geographical, visually for structure of collectively means. Also, a narrow entrance and enclosure topography are areas which arouse atmosphere of paradise. In addition, Aunuisamdong's landscape structure, which was previously divided into individual Dongcheon, was expanded into a single integrated landscape structure of Dongcheon. This is different from the general landscape development of common Dongcheon with the same starting and ending points and sightseeing routes.

In the composite beam subjected to the hogging moment it is very difficult to evaluate the influence of the reduction of slab stiffness due to cracks and their development on the horizontal shear behavior of shear connection. In this study, a 3D FE model is developed by which one can analyze the composite action in the composite beam subjected to the hogging moment. In this FE model, each structural member and shear connection are modeled as similar as possible to details of the composite beam. Bending behaviour, and composite action which could not be analyzed using the existing 1D or 2D FE model are investigated by the 3D model. Analysis results show that the reinforcement ratio and crack behaviour of the slab are main factors which exert a strong influence on the composite action. According to the analysis results about load-slip behavior, initial crack of slab and yielding of rebars have a influence on the slip stiffness of shear connection. The existing experimental results, that the design of partial interaction can be more efficient in designing of shear connection of the composite beams, are indirectly verified by the FE analysis.

The FAT (File Allocation Table) compatible file system has been widely used in mobile devices and memory cards because of its data exchangeability among numerous platforms recognizing the FAT file system. By the way. modern embedded systems have tough demands for instant power failure recovery and superior performance for multimedia applications. The key issue is how to achieve the goals of superior write performance and instant booting capability while controlling compatibility issues. To achieve the goals while controlling compatibility issues. we devised a temporary meta-data journaling scheme for a FAT compatible file system. Benchmark results of the scheme implemented in a FAT compatible file system shows that it really improves write performance of the FAT file system by converting small random write for meta-data update to a large sequential write in journaling area. Also, it provides natural way to implement the instant booting capability. Nevertheless, the file system compatibility is temporarily compromised by the scheme because it stores updated meta-data in the temporary journaling area rather than to their original locations. However, the compatibility can be fully recovered at any time by journal-flushing that copies meta-data in journaling area to their original locations. Generally, the journal-flushing is done before un-mounting a memory card so that it can be used in other mobile devices which recognized FAT file system but not the temporary meta-data journaling scheme.

Free Learning Semester, the new education policy of middle schools in Korea, will be completely implemented in 2016. The purpose of this study was to explore the school experiences of middle-school students in the Free Learning Semester through qualitative approach. In-depth interview was conducted with 8 middle-school students from the purposive sampling. As a result of the analysis, 10 essential themes were identified. Themes were as follows: 'Struggling from the performance evaluation with biting the bullet', 'Great pressure on final examination that is only once a year', 'Inconvenience of career education experience', 'Higher level of friendship', 'Double face of discrimination and respect', 'Chance to adaptation between elementary and middle-school', 'Regret about fleeting time without thought', 'Ambivalence of freedom and suppression', 'Warm place with peer', 'Being pushed rehearsal wearing other's cloth'. In conclusion, the nature of lived experience of middle-school students in the Free Learning Semester is based on ambivalence of various aspects, but is predominant in 'higher level of friendship'. It suggested that the Free Learning Semester can be a positive alternative to existing education system that made students to compete each other. It is expected to be able to discuss the future policy direction using the result of this study which explored the nature of lived experience related to the Free Learning Semester.

Microorganism survived in the root canal after root canal cleaning and shaping procedure is a main cause of root canal treatment failure. There are several mechanisms for the bacteria to survive in the root canal after chemomechanical preparation and root canal irrigation. Bacteria organized as biofilm has been suggested as an etiology of persistent periapical lesion. Recent studies were focus on removal of Enterococcus faecalis biofilm due to the report that the persistence of this bacteria after root canal treatment may be associated with its ability to form biofilm. Several investigations demonstrated that current root canal treatment protocol including use of NaOCl, EDTA and Chlorhexidine as irrigants is quite effective in eliminating E. faecalis biofilm. However, this microorganism still can survive in inaccessible areas of root canal system and evade host immune response, suppress immune activity and produce biofilm. Up to date, there is no possible clinical method to completely get rid of bacteria from the root canal. Once the root canal treatment failure occurred, and conventional treatment incorporating current therapeutic protocol has failed, periapical surgery or extraction should be considered rather than prolong the in effected retreatment procedure.

In this study, we have isolated and identified a proteolytic bacterium from conventional Cheongkukjang. We also characterized several bioactivity of Cheongkukjang, which was fermented by an isolated strain. One strain out of about $10^4$ strains obtained from Cheongkukjang showed relatively high proteolytic activity was selected and named as a Bacillus subtilis LSH805 strain. White soy-bean Cheongkukjang possessed less odor and more viscous substance than black soy-bean Cheongkukjang. Cheongkukjang showed fibrinolytic activity, and about 1,500 mg fibrin was degraded after 20 h incubation. Although nitric oxide (NO) assays of soy-bean and Cheongkukjang were almost the same, their activities were significantly higher than that of no treatment. Activity of water fraction of Cheongkukjang was somewhat higher than that of soy-bean. Fibrinolytic and NO assays of Cheongkukjang suggest that Cheongkukjang, which was fermented by an isolated strain may be a useful candidate for natural fibrinolytic and macrophage-stimulating agents.

The objective of this study is to observe the exclusive breastfeeding(EBF) rate and to identify factors which influence EBF by postpartum period. The data were obtained from the 2015 National Fertility Survey, Family Health and Welfare in Korea, and secondary data analysis were employed for 1,839 mothers who gave birth to baby between January 2013 and February 2015. Data were analyzed using SPSS 25.0 program with descriptive statistics, chi-square test and multiple logistic regression. The EBF rate at the 1st and 6th month of postpartum were 54.0%, 9.4% respectively. The significant influencing factors on the EBF at the 1st month of postpartum were age of mother, baby's birth rank, type of delivery, breastfeeding within 1 hour after delivery. The significant influencing factors on the EBF at the 6th month of postpartum were age of mother, living area, EBF in the first month. We found that the influencing factors on EBF differed by postpartum period. In order to improving the rate of EBF, it is recommended that taioed interventions is needed considering the factors affecting the EBF by postpartum period.

For the communication between human and computer in an interactive computing environment, the gesture recognition has been studied vigorously. The algorithms which use the 2D features for the feature extraction and the feature comparison are faster, but there are some environmental limitations for the accurate recognition. The algorithms which use the 2.5D features provide higher accuracy than 2D features, but these are influenced by rotation of objects. And the algorithms which use the 3D features are slow for the recognition, because these algorithms need the 3d object reconstruction as the preprocessing for the feature extraction. In this paper, we propose a method to extract the 3D features combined with the 3D object reconstruction in real-time. This method generates three kinds of 3D projection maps using the modified GPU-based visual hull generation algorithm. This process only executes data generation parts only for the gesture recognition and calculates the Hu-moment which is corresponding to each projection map. In the section of experimental results, we compare the computational time of the proposed method with the previous methods. And the result shows that the proposed method can apply to real time gesture recognition environment.
