이동 컴퓨팅 환경에서 이동 사용자는 무선 통신망의 협소한 대역폭을 효율적으로 사용하기 위하여 자주 사용하는 데이타를 자신의 캐쉬에 저장하여 사용한다. 이동 트랜잭션의 정확성을 보장하기 위하여 캐쉬 데이터는 서버에 있는 데이타와 일관성이 유지되어야 한다. 이 논문은 비동기적 방송을 하는 이동 컴퓨팅 환경에서 이동호스트의 이동으로 인하여 이동호스트가 캐쉬한 데이터가 서버에 있는 데이타와 일관성이 위배될 때, 효율적으로 캐쉬 일관성을 유지하도록 하는 새로운 정책을 제안한다. 이 정책은 갱신율이나 갱신 패턴이 변하여도 무효화되는 데이터의 개수에 영향을 받지 않으며, 전송하는 무효화 메시지의 량은 항상 일정하고 상대적으로 작다. 따라서, 무선망의 협소한 대역폭을 향상시키고 통신 비용을 감소시킨다.

A current autonomous vehicle determines its driving strategy by considering only external factors (Pedestrians, road conditions, etc.) without considering the interior condition of the vehicle. To solve the problem, this paper proposes "An Optimal Driving Support Strategy(ODSS) based on an Genetic Algorithm for Autonomous Vehicles" which determines the optimal strategy of an autonomous vehicle by analyzing not only the external factors, but also the internal factors of the vehicle(consumable conditions, RPM levels etc.). The proposed ODSS consists of 4 modules. The first module is a Data Communication Module (DCM) which converts CAN, FlexRay, and HSCAN messages of vehicles into WAVE messages and sends the converted messages to the Cloud and receives the analyzed result from the Cloud using V2X. The second module is a Data Management Module (DMM) that classifies the converted WAVE messages and stores the classified messages in a road state table, a sensor message table, and a vehicle state table. The third module is a Data Analysis Module (DAM) which learns a genetic algorithm using sensor data from vehicles stored in the cloud and determines the optimal driving strategy of an autonomous vehicle. The fourth module is a Data Visualization Module (DVM) which displays the optimal driving strategy and the current driving conditions on a vehicle monitor. This paper compared the DCM with existing vehicle gateways and the DAM with the MLP and RF neural network models to validate the ODSS. In the experiment, the DCM improved a loss rate approximately by 5%, compared with existing vehicle gateways. In addition, because the DAM improved computation time by 40% and 20% separately, compared with the MLP and RF, it determined RPM, speed, steering angle and lane changes faster than them.

This study purported to analyze the condition of the degree standardization and types of global ads. in the multinational fashion brand corporations. The analyzed ads. were sampled from monthly magazines on same seasons in 1997. This study was done by means of checklists were modified other researcher's research measurments. Researcher counted of advertising message. Zero point meant perfect stan-dardization and 13 points meant perfect non-standardization. The types of advertising appeal were analyzed according to constituent unit's expression types. The results of the study proved that the degree of standardization was considerably high, which means that the multinational fashion brand corporations used the standardization strategy. In particular, the degree of standardization in sports wear and casual wear ads. was low compared with the degree of standardization in the other ads. Most of the global fashion ads. were composed of illustrations only. Besides, emotional appeal type was usually used in glabal fashion ads.

This paper describes diagnosis strategy of the Flexible Multiple Fault Diagnosis Module for forecasting faults in system and deciding current machine state form sensor information. Most studydeal with diagnosis control stategy about single fault in a system, this studies deal with multiple fault diagnosis. This strategy is consist of diagnosis control module such as backward tracking expert system shell, various neural network, numerical model to predict machine state and communication module for information exchange and cooperate between each model. This models are used to describe structure, function and behavior of subsystem, complex component and total system. Hierarchical structure is very efficient to represent structural, functional and behavioral knowledge. FT(Fault Tree). ST(Symptom Tree), FCD(Fault Consequence Diagrapy), SGM(State Graph Model) and FFM(Functional Flow Model) are used to represent hierachical structure. In this study, IA(Intelligent Agent) concept is introduced to match FT component and event symbol in diagnosed system and to transfer message between each event process. Proposed diagnosis control module is made of IPC(Inter Process Communication) method under UNIX operating system.

Over the past two decades in the United States, social marketing has become an increasingly popular means of delivering nutrition education for the purpose of eliciting a specific behavior change. This manuscript defines social marketing via traditional marketing concepts and jargon, as well as through a communications strategy that can be used to guide message and campaign development. Research and evaluation strategies necessary to support the development and assessment of campaign promotions, is discussed. Four campaigns implemented in the United States, and one campaign implemented in Indonesia, are discussed in terms of the strategies presented. These campaigns illustrate how this educational technique and an array of assessment approaches have been applied to varied nutritional issues across diverse target audiences and settings. Practical recommendations, as well as discussion of issues regarding the advantages and disadvantages of using social marketing as an educational strategy, campaign sustainability, and philosophical considerations regarding the use of this educational approach, are addressed.

This paper proposes that we need a simpler method for developing the Website strategy for public institutions. The research objectives are threefold: (1) A model that relates to the monitoring of Website strategy in the public sector is proposed. The model includes basic dimensions and a $2{\times}3$ matrix that is a simplified version of the Mohammed et dl.s Marketspace Matrix. (2) The model is tested empirically with a sample of 56 Websites selected from govemment agencies, military organizations and police stations in Korea. (3) The effect of dimension/factors on the innovation level is tested. A special attention is paid to online attracting that is important for public institutions which usually do not use offline advertising aggressively. Results from regression analyses show that main dimensions (Marketing Drivers and relationship Stages) and three factors (Basic Information, Support Information, and Participation) in the matrix are all significantly influential on the innovation level, but the Attracting is not. Colorful designs and attracting features of a homepage have not necessarily anything to do with innovation. This message can offer a good piece of advice for managers of Websites.

Although much research has been conducted in the area of authentication in wireless networks, vehicular ad-hoc networks (VANETs) pose unique challenges, such as real-time constraints, processing limitations, memory constraints, frequently changing senders, requirements for interoperability with existing standards, extensibility and flexibility for future requirements, etc. No currently proposed technique addresses all of the requirements for message and entity authentication in VANETs. After analyzing the requirements for viable VANET message authentication, we propose a modified version of TESLA, TESLA++, which provides the same computationally efficient broadcast authentication as TESLA with reduced memory requirements. To address the range of needs within VANETs we propose a new hybrid authentication mechanism, VANET authentication using signatures and TESLA++ (VAST), that combines the advantages of ECDSA signatures and TESLA++. Elliptic curve digital signature algorithm (ECDSA) signatures provide fast authentication and non-repudiation, but are computationally expensive. TESLA++ prevents memory and computation-based denial of service attacks. We analyze the security of our mechanism and simulate VAST in realistic highway conditions under varying network and vehicular traffic scenarios. Simulation results show that VAST outperforms either signatures or TESLA on its own. Even under heavy loads VAST is able to authenticate 100% of the received messages within 107ms. VANETs use certificates to achieve entity authentication (i.e., validate senders). To reduce certificate bandwidth usage, we use Hu et al.'s strategy of broadcasting certificates at fixed intervals, independent of the arrival of new entities. We propose a new certificate verification strategy that prevents denial of service attacks while requiring zero additional sender overhead. Our analysis shows that these solutions introduce a small delay, but still allow drivers in a worst case scenario over 3 seconds to respond to a dangerous situation.
