Recently, the technologies related with location-based services have been a promising and vigorously researched area in mobile telecommunication industry. LBS have obtained increasingly high attention particularly in domestic area, due to increases in various LBS services supplied by mobile telecommunication companies. LBS technologies are classified by sub-technology such as location determination technology, LBS platform technology, and LBS application services technology. In this paper, I have examined the trend of LBS technologies by analyzing the issued or published patents from 1991 to 2005. The analyzed results are very useful for avoiding overlapping efforts in developing the LBS related technologies, and searching the direction of development of technologies which are different from previous ones.

Eight distinct bacteria were isolated form diseased mycelia of the edible mushroom, Pleurotus eryngii. 16S rDNA sequence analysis showed that the isolates belonged to a variety of bacterial genera including Bacillus (LBS5), Enterobacter (LBS1), Sphingomonas (LBS8 and LBS10), Staphylococcus (LBS3, LBS4 and LBS9) and Moraxella (LBS6). Among them, 4 bacterial isolates including LBS1, LBS4, LBS5, and LBS9 evidenced growth inhibitory activity on the mushroom mycelia. The inhibitory activity on the growth of the mushroom fruiting bodies was evaluated by the treatment of the bacterial culture broth or the heat-treated cell-free supernatant of the broth. The treatment of the culture broths or the cell-free supernatants of LBS4 or LBS9 completely inhibited the formation of the fruiting body, thereby suggesting that the inhibitory agent is a heat-stable compound. In the case of LBS5, only the bacterial cell-containing culture broth was capable of inhibiting the formation of the fruiting body, whereas the cell-free supernatant did not, which suggests that an inhibitory agent generated by LBS5 is a protein or a heat-labile chemical compound, potentially a fungal cell wall-degrading enzyme. The culture broth of LBS1 was not inhibitory. However, its cell-free supernatant was capable of inhibiting the formation of fruiting bodies. This indicates that LBS1 may produce an inhibitory heat-stable chemical compound which is readily degraded by its own secreted enzyme.

Location Based Services, or LBS refers to value-added service by processing information utilizing mobile user location. With the rapidly increasing wireless internet subscribers and world LBS market, the various location based applications are introduced such as buddy finder, proximity and security services. As the killer application of the wireless internet, the LBS has preconsidered technology about location determination technology, LBS middleware server for various application, and diverse contents processing technology. This paper describes the open architecture for LBS platform ensuring interoperability among the wireless networks and various location-based application services and the functional requirements for the LBS platform. The LBS platform in a narrow sense provides a standard interfaces for location management and network management for location services as follows, positioning (location acquisition through network or/and handset), location managing, location based functions, profile management, authentication and security, location based billing, information roaming between carriers and the system monitoring independent to specific network or ISP/CPs(Content Providers).

A location-based service or LBS in a cellular telephone network is a service provided to the subscriber based on his current geographic location. This position can be known by user entry or a GPS receiver that he carries with him, but most often the term implies the use of a function built into the cell network that uses the known geographic coordinates of the base stations through which the communication takes place. One implication is that knowledge of the coordinates is owned and controlled by the network operator, and not by the end user. Location utility service provides two kinds of functions, geocoder and reverse geocoder. Geocoder converts an address into a coordinate and reverse geocoder changes a coordinate into an address. Because location utility service is the first step to progress LBS, various servises such as directory, routing, presentation, and etc require to access that. In this paper, we will describe the architecture of LBS platform and the concept and the role of location utility service.

The purpose of this study was to evaluate isometric trunk extension strength in hemiplegic patients, and to compare that with normal subjects to find a correlation between trunk extension strength and the functional independent degree in hemiplegic patients. Fifteen hemiplegic male patients (mean age $55.2{\pm}10.2$ years) and twenty-five healthy male subjects (mean age $54.6{\pm}10.3$ years) completed isometric trunk extension. Strength was measured at 0, 12, 24, 36, 48, 60, and 72 degrees of trunk flexion. The functional independent degree was assessed by Functional Independence Measure (FIM). Mean isometric trunk extension strength was 91.2 ft-lbs, 120.7 ft-lbs, 142.3 ft-lbs, 156.4 ft-lbs, 173.5 ft-lbs, 184.1 ft-lbs, and 195.3 ft-lbs in the hemiplegic patients group, and 135.6 ft-lbs, 175.6 ft-lbs, 204.4 ft-lbs, 221.9 ft-lbs, 231.2 ft-lbs, 246.8 ft-lbs, and 259.7 ft-lbs in the normal subjects group. The values of isometric trunk extension strength had a descending linear correlation pattern from trunk flexion angle to extension angle. Trunk extension strength in hemiplegic patients was significantly lower than that of normal subjects (p<.05) but did not correlate with the FIM total score (p>.05). Therefore, the isometric trunk extension strength in hemiplegic patients was lower than that of normal subjects and did not correlate with the functional independent degree.

With emergence of smart technologies(e.g., smartphones), Location-Based Services(LBS) are expected to provide more enhanced values utilizing consumers' personal information than other smart services. However, in contrast to existing smartphone applications, LBS could raised severe consumer's privacy concerns because of rapidly changing information sensitive to consumers. In this context, the purpose of this study is to explore relationships among privacy concerns reduction, trust and intention to use LBS by examining the effect of precedence factors(social presence, reputation, mobile literacy, ability of information control) of privacy concern reduction. In addition, the study investigates the role of personal innovation as a moderating effect between privacy concern reduction and intention to use LBS. The results showed that the proposed precedence factors of privacy concerns with a exception of Mobile Literacy had a positive impact on privacy concerns reduction that then positively affected trust and intention to use LBS. In addition, the relationship between trust and intention to use LBS was significantly supported. Finally, personal innovation as a moderating effect significantly influenced the relationship between privacy concern reduction and intention to use LBS. This study is expected to be a reference for a subsequent study about the spread of LBS application of smartphone. Also, the finding of this study is meaningful for helping service direction to firms providing LBS.

무선 인터넷 기술의 발달과 응용의 확산으로 인하여 위치 정보를 이용한 서비스 형태는 아주 다양하여 지고 있으며, LBS(Location-Based Services)라는 형태로 국내외 시장에서 급속히 확장하고 있다. LBS 플랫폼은 이러한 위치 기반 서비스를 가능하게 하는 핵심 요소이며, 위치 정보 제공 게이트웨이, 위치 응용 서버, 핵심 기능 제공 서버 등과의 상호 운용을 지원해야 하며, 개인 및 서비스에 대한 프로파일 관리, 과금 처리, 이동체 트리거 등의 기능을 제공하는 시스템이다. 즉, 모든 위치기반 서비스를 수행하려고 하는 개인 혹은 응용 서비스 제공자들은 이러한 LBS 플랫폼을 거쳐, 위치 및 다양한 핵심 기능의 조합 형태인 서비스를 제공 받게 된다. 표준화된 소프트웨어 기술인 웹서비스는 LBS 플랫폼과 타 시스템(솔루션, 핵심 기능 제공 서버, 위치 정보 제공 서버 등)과의 인터페이싱을 가능하게 하는 표준 인프라이다. LBS 플랫폼 웽 서비스는, 솔루션 서버에서 요청하는 서비스에 대한 과금 처리를 위한 자체 과금 비즈니스 모델을 포함하고 있으며, 이러한 과금에 대한 처리를 수행하면서 타 시스템과의 상호 운용은 여러 가지 형태로의 구성이 가능하다. 이에 본 논문에서는 LBS 플랫폼이 상호 운용하는 주요 시스템과의 인터페이싱을 위한 웹 서비스 구성 방법에 대한 방안을 제시하고자 한다.
