U-City건설사업이 시작된 지 수년이 지났지만 아직도 우리가 U-City를 인지하고 체감하기에는 부족한 것이 사실이다. 그러한 원인 중에 하나는 U-City가 그 속성상 보다 체계적인 개발과 제도적 관리가 요구됨에도 가시적인 성과만을 위해 개별사업자를 중심으로 한 난개발에 있다고 볼수 있다. 다행히도 올 3월 U-City의 계획, 건설, 운영관리 등을 위한 "유비쿼터스도시의 건설 등에 관한 법률"이 공포되고 앞으로는 관련법률에 의해 체계적으로 U-City가 추진될 것으로 보여 이런 상황은 상당부분 해소될 것으로 예상된다. 이에 본 연구에서는 과거 각 지자체들의 U-City 건설사업절차와 문제점들을 분석하고 BPR방법론을 이용하여 새로운 법률에 맞춰 U-City건설사업 프로세스를 재설계함으로써 체계적인 사업추진을 통해 지속가능한 U-City의 개발이 될 수 있도록 하는데 그 목적을 두었다.

Purpose: Mortality rates following hip fracture surgery have been well-studied. This study was conducted to examine mortality rates in asymptomatic patients presenting for treatment of acute hip fractures with concurrent positive COVID-19(+) tests compared to those with negative COVID-19(-) tests. Materials and Methods: A total of 149 consecutive patients undergoing hip fracture surgery during the COVID-19 pandemic at two academic medical centers were reviewed retrospectively. Patients were divided into two groups for comparative analysis: one group included asymptomatic patients with COVID-19+ tests versus COVID-19- tests. The primary outcome was mortality at 30-days and 90-days. Results: COVID-19+ patients had a higher mortality rate than COVID-19- patients at 30-days (26.7% vs 6.0%, P=0.005) and 90-days (41.7% vs 17.2%, P=0.046) and trended towards an increased length of hospital stay (10.1±6.2 vs 6.8±3.8 days, P=0.06). COVID-19+ patients had more pre-existing respiratory disease (46.7% vs 11.2%, P=0.0002). Results of a Cox regression analysis showed an increased risk of mortality at 30-days and 90-days from COVID-19+ status alone without an increased risk of death in patients with pre-existing chronic respiratory disease. Conclusion: Factors including time to surgery, age, preexisting comorbidities, and postoperative ambulatory status have been proven to affect mortality and complications in hip fracture patients; however, a positive COVID-19 test result adds another variable to this process. Implementation of protocols that will promote prompt orthogeriatric assessments, expedite patient transfer, limit operating room traffic, and optimize anesthesia time can preserve the standard of care in this unique patient population.

The soil contamination by heavy metals in playgrounds of kindergartens in Vilnius city is analysed in this article. The aim of this research is to investigate and evaluate soil contamination by heavy metals in playgrounds of kindergartens in different territories of Vilnius city. Concentrations of heavy metals were measured using Thermo Fisher Scientific Niton$^{(R)}$ XL2 X-ray fluorescence spectrometer. Maximum allowable and background concentrations that are given in Lithuanian hygiene standard and Lithuania geochemical atlas are used to compare and evaluate concentrations of heavy metals. Concentrations of heavy metals and their spatial distribution were analysed in order to exclude the most contaminated areas relating with different functional areas of the city. Geo-statistical analysis and maps of spatial distribution were developed using IDW interpolator in ArcMap software. Detail soil surveys helps to assess the extent of anthropogenic impact in different parts of the city which can be harmful to the soil ecosystem and human health. Such researches can help to change or select different function for city areas in territorial planning process.

The purpose of this study is to derive a model of urban regeneration business using idle facilities in the old city center. The scope of the study was set as empty houses and empty stores owned by private companies, and analyzed the 50 central city revitalization projects using idle facilities in 14 local cities in Japan. The results of this study are follows; First, as an urban regeneration strategy using idle facilities in the old town, it was a combination of other functions centering on commercial functions or introducing new functions required in the city center. Second, various financial supports have been provided to induce the utilization of idle facilities by the private sector, and different strategies have been implemented for businesses that need maintenance first. Third, based on the analysis results, it was possible to derive urban regeneration business model. Fourth, in order to operate smooth business, it is a need for an organization that is in charge of reviewing the consistency of upper-level planning and urban guiding functions such as urban revitalization plan, balance review of expenditure and revenues by cost subsidy and loan repayment, consultation among the business partners.

Objectives: This study was to compare two healthy cities, Liverpool in England and Wonju in Korea, which evaluated healthy city projects and to reorient evaluation strategy which fits into Korean Healthy cities. Methods: Comparatives analysis was used by reviewing documents, healthy city plan and evaluation report, of two cities. Results: Healthy city projects in two cities, fifteen programs were identical items among twenty-seven but there were differences in seven items for Liverpool and five items for Wonju. In Liverpool evaluation was done by a stakeholder group called Liverpool Local Involvement Network(LINK), while in Wonju by Yonsei Healthy City Research Center. The evaluation tool was two types; quantitative and qualitative analysis. Liverpool mostly used qualitative and added quantitative, vice versa in Wonju. Conclusions: Evaluation plan for Healthy city projects need to be made in the first phase of the projects, instead of in the end. Moreover, it is important to include stakeholder in conducting qualitative analysis for unquantifiable evidence of effectiveness, as well as quantitative analysis.

유비쿼터스 사회가 도래함에 따라 유비쿼터스 기술을 도시에 적용한 u-City가 개발되고 있다. u-City는 다양한 정보화 기기들이 존재하며 정보화 기기 사이를 연결하는 다양한 네트워크 기술이 상존한다. u-City의 핵심 요소인 u-City 통합운영센터는 u-City 내의 모든 서비스를 처리하도록 설계되었으며, 도시를 통제 관리하는 중요한 업무를 수행한다. 이 중에서 보안관리 업무는 시스템에서 수집, 가공, 산출하는 데이터 및 정보의 보안유지를 위해 중요한 부분이다. 따라서 본 논문에서는 u-City 통합운영센터의 보안유지를 위한 기술적, 물리적, 관리적인 측면에서 보안관리 대책을 제시하였다.

This study examines the 1980 Census and the 1987 Travel Survey data sets, in order to identify commuting trends in the Seoul Metropolitan Area. The commuting field of Seoul includes the cities and counties contiguous to Seoul, as well as Inchon, Suwon and Ansan City and Paju County. The study finds little support for the expansion of the commuting field toward distant counties of Kyonggi Province; instead an intensification of commuting within the field is more salient. The most prominent trend, within the city limit of Seoul, is that journey-to-work toward the city center has decreased whereas peripheral journeys increased considerably. The work trips have increased most in the southwestern sector of the city; a moderate increase in the northeastern and southwestern sectors; and decreases in the center and the northwestern sector of the city. Factorial analyses of the work trip data also reveal the emergence of sub-regions of journey-to-work in the peripheries of the city. Such a spatial pattern of commuting changes resemble that of population changes, and correspond in part to the layout of the subway system.

최근 정보기술과 유비쿼터스기술을 바탕으로 도시를 미래화하는 유비쿼터스도시(U-City)구축이 범 국가적으로 추진되고 있다. 이에, 정부에서는 2008년 9월 25일 유비쿼터스도시의 건설 등에 관한 법률 시행령을 발표하였으며, 유비쿼터스도시서비스(U-City Service)를 크게 행정, 교통, 보건 의료 복지, 환경, 방범 방재, 시설물 관리, 교육, 문화 관광 스포츠, 물류, 근로 고용 등의 분야로 구분하였다. 이러한 유비쿼터스도시서비스를 제공하고 운영 및 관리하는 시설로 유비쿼터스도시 통합운영센터(U-City Management Center)는 다양한 유비쿼터스도시서비스를 효과적으로 연계하여 서비스에서 발생되는 다양한 도시정보를 통합, 분석하고 제공하는 유비쿼터스도시 핵심기능을 담당한다. 하지만 이러한 유비쿼터스도시 통합운영센터의 구축은 운영조직구성, 운영비용확보, 통합서비스 제공방안, 법 제도 정비 등의 해결과제를 가지고 있어 구현방안에 대한 구체적인 연구가 요구된다. 본 연구에서는 선행연구를 바탕으로 유비쿼터스도시 통합운영센터에서 기본적으로 제공되어야 할 유비쿼터스도시서비스 유형을 제시하고 정의한다.

현재 국내 외에서 유비쿼터스 기술 기반의 혁신도시 개념인 u-City의 추진이 활발히 진행되고 있으며, 이를 위한 통합운영센터에 대한 연구 및 구축도 진행 중에 있다. 하지만 이러한 u-City 통합운영센터에 대한 기술적인 접근은 증가하는 반면, 이를 관리하는 관리자 권한에 대한 연구는 미비한 실정이다. 실제 모든 정보를 관리하게 될 관리자의 권한관리가 이루어지지 않을 경우, 이로 인한 보안 관련 문제점이 발생 할 수 있다. 따라서 본 논문에서는 u-City 통합운영센터의 관리자로 인해 발생할 수 있는 보안 문제점을 분석하고, 이를 효과적이고 체계적으로 해결하기 위한 관리자 권한관리 체계에 대해 제안 한다.

This paper addresses the problem of locating a telephone switching center at new establishing city or town. There have been several studies on the location of telephone switching center at an existing telephone network to cope with the expanding subsciber's demand, in most of which only the economic factors were considered and was determined where the switching center is established in order to minimize the total cost. This paper, However, deals with the social factors as well as the economic ones. We develop a location model considered these two factors simultaneously by using a fuzzy approach. Finally, we apply the model to locate a new telephone switching center at the Haeundae where the Pusan City intends to construct a new town.
