This study applied the value of floor-area-ratio standard calculation method to case areas and analyzed them to overcome the limits of previous studies in calculation methods for area standards and land price (value) standard development rights. The results are presented as follows: First, criteria to select sending areas and receiving areas are needed. Second, calculation methods based on the value of floor-area-ratio standard can be widely used as standardized criteria in various areas. Third, for the connection of sending areas with receiving areas, the connections of 1:1, n:1, 1:n, and n:n are available and the location of possible dealing areas should be considered. Also, the choice of connecting unions that meet the purpose of TDR presented by local governments is available. Fourth, for Gwangju, as receiving areas downtown provide higher profits than previous renewal projects, the application of TDR is available. Application methods to overcome problems are presented as follows: First, criteria to select sending and receiving areas should be prepared and implemented in an order of priority. Second, in calculating development rights, methods based on the value of floor-area-ratio standard should be used. Third, the standards and principles of sending and receiving areas should be designated and possible dealing areas should not be limited.

지금까지의 통신망은 음성을 위한 공중통신망과 데이터 전송을 위한 공중데이터망으로 각각의 데이터 형태에 따른 전용망으로 발전해 왔으나 이것은 경제적으로나 효율면에서 큰 손실을 가져온다. 그러므로 음성과 데이터를 디지탈로 통합 처리하는 ISDN은 서비스 사용자에게 큰 이익을 준다 그러나 ISDN을 좁은 지역까지 확대하기 위해서는 LAN 환경에서의 음성과 데이터의 혼합 전송에 관한 연구가 필요하므로 본 논문에서는 현재 많이 사용하고 있는 이더넷과 토큰링에서의 음성과 데이터의 혼합 전송에 관한 알고리즘을 제안한다.

In daily activities, people often perform two or more tasks simultaneously. This is referred to as dual-tasking or multi-tasking. The purpose of this study was to examine the effects of performing dual tasks while using a mobile phone on static and dynamic postural stability. Twenty-four subjects were asked to stand on a force plate and then instructed to perform a balance task only (BT), a balance task while listening to music (BTL), a balance task while talking on the mobile phone (BTT), and a balance task while sending text messages (BTS). We used the BioRescue$^{(R)}$ to measure postural sway and limit of stability for static and dynamic postural stability. Also the star excursion balance test (SEBT) was used to measure dynamic postural stability. A one-way ANOVA with repeated measures was used to compare the effects of the BT, BTL, BTT, and BTS. The Bonferroni's post hoc test was used to determine the differences among four tasks. Carrying out the BTS significantly decreased the limit of stability compared with carrying out the BT, BTL, and BTT (p<.05). In limit of stability, total surface area of BTT was more significantly decreased than that of BT and total surface area of BTS was more decreased than that of BT, BTL and BTT (p<.05). In the SEBT, the BTS displayed significantly smaller reach distance values compared with the BT or BTL (p<.05). These findings suggest that performing the balance task while sending text message on the mobile phone decreases dynamic postural stability, whereas performing the same task while listening to music using the mobile phone does not. Therefore, it requires more attention to maintain dynamic balance while sending text messages.

본 논문은 차량 내부 네트워크에서 메시지 인증을 사용하여 사이버 공격을 탐지할 수 있는 보안 시스템을 제안한다. 자동차 내부 네트워크는 브로드캐스트 방식으로 메시지를 전송하고 노드의 식별자를 사용하지 않으므로 송신자를 식별할 수 없다. 송신 노드는 제어 데이터를 암호화 해시함수를 사용하여 메시지인증코드를 생성하여 제어 데이터와 같이 전송한다. 메시지인증코드 생성 시, 결과의 임의성을 증가시키기 위해서 다차원 카오틱 맵을 적용하였다. 수신 노드는 수신한 메시지의 제어 데이터에 대해 생성된 메시지인증코드를 수신 메시지에 존재하는 메시지인증코드 값과 비교하여 전송된 메시지의 위조 여부를 탐지한다. CANoe와 CAPL(Communication Access Programming Language)을 사용하여 차량 내부 네트워크 환경을 구성하고 사이버 공격을 수행하여 성능을 평가하였으며 탐지율 100%의 성능을 보였다.

The Air Quality Sensor(AQS), located near the fresh air inlet, serves to reduce the amount of pollution entering the vehicle cabin through the HVAC(heating, ventilating, and air conditioning) system by sending a signal to close the fresh air inlet door/ventilation flap when the vehicle enters a high pollution area. One chip sensor module which include above two sensing elements, humidity sensor and bad odor sensor was developed for AQS (air quality sensor) in automobile. With this sensor module, PIC microcontroller was designed with back propagation neural network to reduce detecting error when the motor vehicles pass through the dense fog area. The signal from neural network was modified to control the inlet of automobile and display the result or alarm the situation. One chip microcontroller, Atmega128L (ATmega Ltd., USA) was used. For the control and display. And our developed system can intelligently detect the bad odor when the motor vehicles pass through the polluted air zone such as cattle farm.
