As remote sensing technologies are evolving, and more satellites are orbited, the demand for using satellite data for disaster monitoring is rapidly increasing. Although natural and social disasters have been monitored using satellite data, constraints on establishing an integrated satellite-based near real-time disaster monitoring system have not been identified yet, and thus a novel framework for establishing such system remains to be presented. This research identifies constraints on establishing satellite data-based near real-time disaster monitoring systems by devising and testing a new conceptual framework of disaster monitoring, and then presents a feasible disaster monitoring system that relies mainly on acquirable satellite data. Implementing near real-time disaster monitoring by satellite remote sensing is constrained by technological and economic factors, and more significantly, it is also limited by interactions between organisations and policy that hamper timely acquiring appropriate satellite data for the purpose, and institutional factors that are related to satellite data analyses. Such constraints could be eased by employing an integrated computing platform, such as Amazon Web Services(AWS), which enables obtaining, storing and analysing satellite data, and by developing a toolkit by which appropriate satellites'sensors that are required for monitoring specific types of disaster, and their orbits, can be analysed. It is anticipated that the findings of this research could be used as meaningful reference when trying to establishing a satellite-based near real-time disaster monitoring system in any country.

In recent years, artistic programs considering both physical and psychological changes in old age have been implemented in various fields. These programs include participatory activities such as painting, play, singing, photography, dance, cartoon animation and so on. It is known that culture and art education programs lead people to emotional growth and social interaction. In particular, culture and art education for the elderly tends to affect positively on the quality of life. However, there are still lack of teaching methods and curriculums in the filed. It is considered that cartoon has a great potential as a teaching method of culture and art education for elderly. This study aims to discuss ways to vitalize the role of cartoon using the qualitative data of four elderly participants in culture and art education programs. The case study analyses reveled that cartoon program for the elderly not only plays a role to make their daily lives more enthusiastic but also provides a social passage to communicate to world. The Cartoon program designed for the elderly was a tool to reveal their inner world to others, and shed new light on their past memories, and long for the precious moments in life. At the same time, it was a meaningful time to lessen the depth of loneliness in old age, and even to heal their physical disability and emotional conflicts. The hardest part of drawing an cartoon was when it did not turn out as they wished. Based on the study results, the researchers explored the therapeutic usefulness of cartoon for the elderly, and discussed the ways to activate it in the field of elderly welfare.

The purpose of this study was to investigate the relationships among poverty, family structure and functioning, burdens of adult roles and socio-emotional problems. It was especially focused on the relationship between the burden of adult roles and socioemotional problems among children in poverty. The Structural Equation model was employed for analyses. The Theoretical model was established based on previous researches related to poverty and adult roles (for example, parentification and parentified children). Data came from the first wave of 'Seoul Panel Study of Children; SPSC' and subjects consisted of 1,807 4th grade elementary school students and their parents who were located at K-Gu in Seoul. The survey was carried out from October 25th to November 20th in 2005. The Results of the Structural Equation model were congruent with the theoretical expectations. To find a more appropriate model, three kinds of structural models were hypothesized and analysed. In the most appropriate model which had a good model fit, poverty and family structure impacted on socio-emotional problems directly and indirectly. The relationship between poverty and socio-emotional problems was mediated by family functioning and burdens of adult roles. The same mediation process existed between family structure and socio-emotional problems also. In brief, children in poverty or those who have a single parent are more likely to have impaired family functioning, which is likely to cause higher burdens of adult roles. In turn, those who have higher burdens of adult roles are more likely to have socioemotional problems. In conclusion, various theoretical and practical implications for social work practice focusing on the burdens of adult roles or caretaker roles among children in poverty were discussed.

Special theaters were created to provide a sense of immersion and spectacles due to differentiated screens, sound, seating facilities, and advanced services, and also expanded screens. The purpose of this study is to perform comparative analysis of the technical characteristics formats shown in special theaters(3D film, 4DX, IMAX, ScreenX, and VR) in order to identify and find ways to overcome the technological limitations in production. The various formats show differences in field of view depending on the exhibition technology and these differences affect the mise-en-scene, narrative, and editing of the film and consequently result in changes in the production environment and process. Therefore, directors and creators must understand the technological features and limitations of the new formats before making their approach. However, a new format encounters limitations on production sets due to the decline of technical education and succession. In situations where shooting with a special camera is essential, the particular characteristics of each format should be carefully considered from the planning stage but financial problems arise due to increase in production period and cost. To overcome these various obstacles, it is essential to first identify problems and present alternatives through in-depth research on the production set of each format. Finally, this research aims to explore the prototype of each format and analyze the current state of production technology with formats that have not been adapted to the market trends by combining with the other formats and showing that they can survive in new ways.

Congenital Missing Teeth(hypodontia, oligodontia) is the developmental absence of one or more teeth. It has been reported as being the most common anomaly of dental development in human, relatively common in the permanent dentition. In a recent review, Vastardis has quoted incidence ranges of $1.6%{\sim}9.6%$ in the permanent dentition. Brook has quoted a prevalence of $3.5%{\sim}6.5%$ in most populations, with severe hypodontia, defined as the absence of six or more teeth, having a prevalence of $0.3{\sim}0.4%$. The most commonly affected teeth are third molars, followed by maxillary lateral incisor, and second premolars. The etiology is unknown, several hypotheses include trauma, nutritional deficiency, infection, metabolic abnormalities, systemic disease and genetic influence. The multiple congenital missing is commonly associated with specific syndrome or severe systemic abnormalities such as cleft lip & palate and Down's syndrome. These cases present that children have multiple congenital missing teeth in the permanent dentition, without any systemic disease. Management of this condition must be considered orthodontic and prosthodontic treatment comprehensively. In these cases, children were treated by space maintainer or orthodontic appliance and follow-up checked.
