The first full-scale u-City operation has started in Dongtan u-City. As local cities take over and operate the u-City, unexpected issues arise such as securing the budget of operating costs and self-providing the costs with business models utilizing the u-City assets. The paper presents a strategy for solving these issues. The strategy provides a foundation(infrastructure) for long-term operation models which may reduce the long-term operating costs. In order to establish the economic operating framework of u-City, suggested are some cost-reduction models based on the operating costs structure. For each model, a base framework with comparative analysis of operating costs is provided. With these models, each u-City may select a relevant model according to the characteristics of it. We hope that the framework provides the foundation for efficient and sustainable u-City operations.

The purpose of this study is to analyze the trend of Korean domestic multi-family housing. For that, this study surveyed 139 apartment complex cases which were sold from December 2002 to December 2005. When Hwasung Dongtan apartment complex was sold in 2004, there were a lot of attempts in various quarters, especially in unit planning and eco-friendly design. Accordingly, it is worthy that analyzing the trend before and after of 2004. As a result, the trend has been moving from 'convenient and high class' to 'LOHAS, one-stop living, convergency, and residents' satisfaction' because leasure and well-living have been the purpose of their living. Therefore, we can predict that B.I. and design identity would be more important, and various contents would be created for residents' community and private life.

Purpose: To evaluate heart failure knowledge and adherence to self-care behaviors, and to identify factors affecting adherence to self-care behaviors among Korean patients with heart failure. Methods: Correlational research using the European Heart Failure Self-care Behavior Scale, the Duke Activity Status Index, the Dutch Heart Failure Knowledge Scale, the New York Heart Association Functional Classification, and the Medical Outcomes Study Social Support Survey was conducted. A total of 280 outpatients with heart failure responded to the five questionnaires. Results: The mean scores for self-care adherence and heart failure knowledge were $31.98{\pm}6.81$ and $8.78{\pm}2.53$, respectively, indicating lower adherence and knowledge than those previously reported. Subjects with lower functional status, more social supports, and greater knowledge of heart failure are more likely to adhere to prescribed regimens. Conclusion: Nurses should focus on patient education and support to improve their adherence to self-care behaviors.

Coronavirus disease-2019 (COVID-19), which started in Wuhan, China, in December 2019 and declared a worldwide pandemic on March 11, 2020, is a novel infectious disease that causes respiratory illness and death. Pediatric COVID-19 accounts for a small percentage of patients and is often milder than that in adults; however, it can progress to severe disease in some cases. Even neonates can suffer from COVID-19, and children may spread the disease in the community. This review summarizes what is currently known about COVID-19 in children and adolescents.

The purpose of this study is to suggest a scheme to provide children safer and more comfortable walking circumstances by survey current walking circumstances of schoolzone ways. A scheme suggested in this study was based on the analysis of survey to elementary school in 3 Newtowns(Dongtan, Dongbaek and Gumdan Districts) and actually surveyed data on school zone, the scheme can be summed up as follows; First, to avoid pedestrian roads being interrupted and to expend waiting space near schoolzone ways, several measures are needed including fixing roads and building additional gateway. Second, to secure pedestrians' safety in school zone ways should be planned and established more security concepts und facilities Third, to improve the walking safety in schoolzone way should be established specially "schoolzone B-plan".

Acromioclavicular (AC) joint dislocations account for about 9% of shoulder injuries. Among them, acute high-grade injury following high-energy trauma accounts for a large proportion of patients requiring surgical treatment. However, there is no gold standard procedure for operative treatment of acute high-grade AC joint injury, and several different procedures have been used for this purpose in clinical practice. This review article summarizes the most recent and relevant surgical options for acute high-grade AC joint dislocation patients and the outcomes of each treatment type.

Maxillary sinus floor augmentation (MSFA) is an essential procedure for implant installation in the posterior maxillary area with vertical alveolar bone deficiency. For the past several decades, MSFA has been refined in terms of surgical methods along with technical progress, accumulation of clinical studies, and development of graft materials and surgical instruments. Although some complications in MSFA are inevitable in clinical situations, management of those complications in MSFA has been well established thanks to many clinicians and researchers. Nevertheless, some rare complications may arise and can result in fatal results. Therefore, clinicians should be well aware of such rare situations and complications associated with MSFA. In this review, the authors present several rare complications regarding MSFA, along with corresponding management strategies through a thorough review of the literature.
