  • Modern roundabouts referred to as relatively safer and more efficient traffic facility than the signalized intersections have been recently deployed and operated and accordingly more research efforts to improve its safety and efficiency have been made so far. This paper introduces a new traffic information system named as Smart Roundabout coupled with Connected Vehicle technique like Vehicle-to-Roadside communication, which has not been attempted before and evaluates its performance with a microscopic simulation model, VISSIM. The proposed system functions to collect driving information of circulating vehicles in the roundabout such as location, speed, critical headway, etc. and help approaching vehicles decide whether to enter the roundabout with an on-board equipment instrumented in the individual vehicle on the basis of calculated gap acceptance of interest. This new system is expected to secure more safety and increase the capacity of the modern roundabout.

  • The purpose of this study was to construct a grounded theory as the basis for developing future nursing interventions by describing and analyzing the holistic lives of the physically handicapped adolescents. The subjects were 10 physically handicapped adolescents who were attending a rehabilitation school located in Kyunggi region and could understand and respond to the questions. The aim and purpose of the study were explained to the subjects, and only those who accepted to participate in the study were selected as the actual study subjects. The study data were collected from July to November 2000. The investigators provided detailed explanations to the subjects about keeping the anonymity of the subjects name and confidentiality of the information provided by the study subjects. The subjects received in-depth interviews by the investigators. Each interview took about 40 minutes to 1 hour and 30 minutes, and each subject received interviews with the range of one to 3 times. All interviews were recorded under the permission of the subjects. The investigators formed field notes after finishing each interview. In the process of data analysis, 'realizing the difficulty due to physical handicap' was found to be the causal condition, whereas' acceptance of physical handicap' was identified as the context. Then, we identified' awaring as the valuable being' as the core phenomenon, 'support from family and social group and spiritual help' as the intervening condition, 'effort for adaptation' as the strategy, and' finding the meaning of life' as the consequence. Through the theoretical model derived from this study, an important aspect the lives of physically handicapped adolescences was identified that' awaring as the valuable being' help them cope better and find the meaning of life in spite of suffering they experience.

  • As foreign tourists visiting Korea increase and Koreans traveling overseas become more frequent, a study on the level of domestic consumers' acceptance of different cultures and the perception towards products from different cultures is needed. In this study, a perceptual curiosity, which is an individual personality, was divided into Diverse perceptual curiosity and Specific perceptual curiosity, and effects of perceptual curiosity on an attitude towards different cultures and an intention to recommend products from different cultures were examined. To prove validity of measurement items and reliability of data, SPSS and LISREL were used and to prove a hypothesis, a structural equation model was used. The study results showed that the Diverse perceptual curiosity, which is Hypothesis 1, had a positive effect on the attitude towards different cultures while the Specific perceptual curiosity, which is Hypothesis 2, did not have a significant effect on the attitude towards different cultures. In addition, it was shown that the attitude towards different cultures, which is Hypothesis 3, had a significant positive effect on the intention to recommend the products from different cultures.

  • Recently, it has been strongly required to establish a systematic and sustainable performance investigation and evaluation framework on governmental funding projects for IT small and medium-sized enterprises. In this paper, Data Envelopment Analysis (DEA) models are adopted for performance evaluation on governmental funding projects for IT small and medium-sized enterprises. A new data structure is proposed for the DEA performance evaluation. Generally, in using DEA models, DEA multipliers restriction is critical to achieve the reliability of DEA optimal solutions. Based on the outputs and inputs considered in this study, Acceptance Region (AR) constraints are generated and incorporated into the DEA models so as to improve the reliability of DEA efficiency scores. Associated with AR Type I (AR-I), AR Global Model (ARGM) constraints, DEA/ (AR-I, ARGM) models are designed and then sensitivity analysis follows investigating the robustness of DEA efficiency scores relating to AR constraints adjustment. Finally, a performance evaluation is illustrated regarding governmental direct funding projects from Ministry of Information and Communication (MIC) in Korea where each project unit (i.e. Decision Making Unit (DMU)) is determined whether it is efficient or not. By using DEA/(AR-I, ARGM) models designed in this paper, robustly efficient DMUs are gradually identified according to the successive AR constraints adjustment. Among 25 DMUs, results show that 6 DMUs such as B, E, G, Q, S, Y are determined as robustly efficient against AR constraints intermediate adjustment.

  • Component-based development(CBD) has acquired a substantial acceptance in both academia and industry as an effective inter-organizational reuse technology. A component framework in product line engineering(PLE) which consists of related components, connectors and their semantics has a greater potential for reusability than components. In frameworks, components are glued with association, dependency and connections. Problems occur like affecting the implementation code of components when they are glued and replaced because the association and dependency relationships between COTS components which are acquired for application development do not match exactly. Especially, a connector may not only connect related components, but also mate partially-matched COTS components fit together. However, little has been studied to date about connectors that can be used practically. In this paper, we present a meta-model for connectors and show how a connector can be designed and implemented in practice. We propose five main patterns of connectors. Proposed major patterns Provide design guidelines for practical and efficient connector configuration based on component framework. And also, applying techniques and applied case studies of the major patterns show greatly increased applicability and reusability of the component without component modification.
