모바일 기기 (스마트폰 ․ 태블릿PC 등)와 다양한 서비스 요구 및 확산으로 위치기반 서비스(LBS, Location Based Service) 시장도 함께 활성화 되고 있다. 위와 같은 위치기반 서비스(LBS)는 재난, 범죄 등 긴급상황에서 국민의 생명 ․ 신체를 보호하기 위한 사회안전망으로서의 중요성이 부각되고 그 활용도도 매우 높다. 이와 관련하여 긴급구조 등의 업무를 담당하고 있는 경찰 ․ 소방 ․ 해양경찰 ․ 보호관찰소 등도 긴급구조와 범죄예방을 목적으로 위치기반서비스(LBS)를 이용하여 위치정보를 수집하고 있다. 그러나 현실은 위치정보 제공업체인 위치정보사업자로부터 정확한 위치정보 데이터를 제공받지 못해 긴급구조를 위한 실질적인 위치추적은 이루어지지 못하고 있다. 따라서 본 논문에서는 위치정보 수집의 근거가 되는 국내 ․ 외 법제 현황과 위치 측정에 사용되는 관련 기술 및 방법에 대해 알아보고, 정확도가 낮은 위치정보로 인해 경찰관서를 포함한 긴급구조기관이 사건 ․ 사고 현장에서 겪는 문제점과 개선방안에 대해 살펴보고자 한다. 개선방안에서 제시되는 위치정보 정확도 및 위치정보 구성요소 명문화, 다양한 위치정보 구성요소를 하나의 화면에 현출하여 주는 위치정보 공간 시각화 시스템 구축, Wi-Fi AP를 활용한 위치측정 실내 측위기술을 활용한 위치측정, 등은 피구조자의 수색범위를 축소하여 신속한 피해회복과 인명구조는 물론 정부에 대한 대국민 만족도와 신뢰도 향상에도 기여를 할 것으로 본다. Due to growth of mobile device(i.e. smartphone, tablet PC) and expansion of service demands, Location Based Service(LBS) markets are growing fast. The importance of Location Based Service (LBS) has been recognised especially in social security sector as it can be valuable mean to protect personal sevurity in emergency such as natural disaster or crime scene. The location based service(LBS) are very imortant and valuable as a social safety net that protects people's personal security in emergency like disaster or crime situation. However until today there has been limitation for police, fire fighter or maritime police to collect and utilize location information of victims using LBS for emergency rescue and crime prevention due to inaccurate location information provided by service companise. In this circumstance, the police·fire figther·maritime police have collected location information of victims using LBS for emergency rescue and crime prevention. But they could have not traced victims using LBS, because are not provided accurate location information from service companies. Hence this paper covers internal and external legislation related to location information collection, and deals with technique and means of location measurement. It also considers the ways to improve current problems that emergency services (including police) experience in crime scene. This paper proposes location information components, accuracy stipulation, building of space visualization system that shows location information components on combined screen, location measurements by Wi-Fi AP(Access Point), location tracking by interior determination technology. It is expected this will reduce the range of victim searching and contributes to quick restoring victims, lifesaving, improvement of people's satisfaction and reliability.

Purpose: This study was conducted to compare clinical features between Mycoplasma pneumonia and viral pneumonia. Methods: We retrospectively analyzed the medical records of 428 patients requiring hospitalization among children younger than 18 years of age in 5 hospitals in Seoul and Gyeonggi-do. There were 131 patients with M. pneumonia and virus coinfection, 167 pa tients with M. pneumonia without virus coinfection, and 130 patients with viral pneumonia. All subjects had radiographic evidence of pneumonia with specimens available for both M. pneumonia and viral testing. Virus was identified using the polymerase chain re action assay in a nasopharyngeal or oropharyngeal swab. M. pneumoniae pneumonia was diagnosed serologically. Results: Human rhinovirus was detected in 60.3% (79 of 131) of children with M. pneumonia accompanied by virus coinfection. Re spiratory syncytial virus (RSV) was detected in 38.2% (50 of 130) of children with viral pneumonia. The mean age was significantly lower in the viral pneumonia group than in the M. pneumonia group with and without virus coinfection. The sex distribution did not differ significantly among the 3 study groups. The procalcitonin level was higher in viral pneumonia and erythrocyte sedimentation rate level was higher in the M. pneumonia group although no significant difference was found in C-reactive protein level between the M. pneumonia and viral pneumonia groups. Conclusion: Clinical features and inflammatory markers between M. pneumonia and viral pneumonia may be useful for the treat ment of community-acquired pneumonia.
