The Unified Modeling Language becomes popular to specify, visualize, construct, and document software-intensive systems, especially in supporting the design phase of software engineering. Most of designs in UML have focused on firm designing of software system structure. Recently, some researches have raised additional demands in many emerging complex software systems, such as aspect-oriented design. In this paper, we work on the dynamic aspect of policy-driven architecture. We present a UML-based high-level modeling of policy-driven management which is applicable in various application domains. In order to manage a number of activities of applications, dynamics and flexibility should be supported with policies consistently on different resources in the same context. Thus, a methodology of meta-modeling to represent dynamic aspects of policy-driven architecture is studied. Based on our methodology, we could achieve meta-modeling to develop a number of policy-driven management applications.

ADR program is designed to solve the problem such as the increase of suits and decision delayed. ADR program has the several significances, decreasing inappropriate cost as time and burden of courts, providing an approachable measure of relief and more efficient tool for settlement of dispute. Particularly ADR program satisfies the needs Intellectual property disputes need specialists that are versed in the subjected problem and, need to be souled quickly in confidence. And parties concerned are not good at the strict judicial procedure in courts, At this point, ADR program holds some advantages over court proceeding for intellectual property disputes. Specialists can be selected as arbitrators or mediator; Cofidentiality may be preserved; Flexibility allows settlement based on mutual commercial interests; Single solution is possible for multiple disputes involving parties from different countries. However, ADR program has not been properly used in. Korea, which is due to not only the lack of understanding the ADR program, but the poor number of filings and settlements. Intermediaries are not professional and also they do not take active hands in disputes. Sometimes, their fairness is asked as peacemakers. Eventually, it is said that this program is not enough to settle international disputes. To activate the ADR program, we can propose the ADR program annexed to court for example. And we can introduce the conciliation and arbitration to disputes in intellectual property. Traditionally arbitration has been a crucial issue in intellectual property disputes. In that intellectual property rights are granted by the local sovereign power, many legal systems in the past maintained the position that the existence, extent, meaning and application of such rights could only be definitively decided by the granting authority or the courts of that country. There is wide recognition that the arbitration of intellectual property is desirable. The law in most of the major countries has been changed in recent years in favor of arbitrability of intellectual property rights. We can also propose ADR on-line.

The purpose of this study is to the examine sense of community of the residents living in an apartment complex and the relevant features of the community facilities provided in the complex, such as actual facility conditions, needs and satisfaction. Five apartment complexes constructed after 2000, each containing more than 500 units were selected for this case study. The actual conditions of the community facilities regulated by current laws were inspected. Those facilities were the administration office, gym, multi-purpose room, sauna and shower room, indoor and outdoor children's play-grounds, study room, etc. 37 residents were interviewed to access their needs and level of and satisfaction with the provided community facilities. Based on the results, we suggest that basic community facilities for exercise, child care and children's recresion need to be provided regardless of the apartment complex size. The respondents revealed a medium level of sense of community, which was psychologically limited to their apartment complex. Indoor and outdoor children's play-grounds had great potential to encourage social interaction between the residents. The findings point to a need for improvement of the current relevant regulations with the perspectives of flexibility and application in terms of space size and mandatory types.

Accidents of commuting vehicles for preschoolers continue to occur despite various safety policies from the government. In order to minimize such accidents, it is necessary to use both the vehicle-mounted safety commutation management software for the driver, and the mobile App to manage the safe schooling of the children that can inform such information to parents in time. In this paper, we describe the design and implementation of the safety management software architecture. The mobile application is designed for Android operating systems. It informs current driving information if the bus as well as the list of current boarded children. Teacher in the bus can manage exceptional cases such as riding child without RFID and unregistered temporary riders like grandparent for convenience and flexibility.

Logic design using multiplexer has been used as a useful method for design convenience and flexibility in structural digital system design. In this paper, we analyze the effect of don't care conditions on logic optimization in a multiplexer-based logic design, which was not discussed enough in the previous studies in multiplexer based logic design, and describe the use of don't care conditions for designing of a single multiplexer and multiple multiplexer-based logic design. Especially, the design method when the number of data input is not 2m (as the number of selection lines is m) is considered. We also describe how to apply the proposed technique to the digital logic design education in conjunction with microprocessor design using Arduino which is widely used in creative engineering education recently.

The purpose of this study was to establish a conceptual management spectrum framework for integrated management of Baekdudaegan area. The conceptual model was developed through a literature survey that includes the concepts from existing relevant systems and other expert sources In conceptual Baekdudaegan management spectrum framework presented here, three different classes (preservation, buffer, and multiple-use) that specify potential management objectives for area functions were classified in order to pursue management flexibility Three primary management classes should be identified by evaluating Indicators of ecological, physical, and social.cultural environments. An application of the framework requires an explicit selection of indicators and their evaluation. For establishing reliability of the framework, it will be desirable to test it empirically in Baedudaegan areas in the future. In addition, systematic case study for selecting appropriate indicators and identifying evaluation standards must be done.

In recent years, high-rise buildings received a renewed interest as a means by which technical and economic advantages can be achieved, especially in areas of high population density. Taller and taller buildings are being built worldwide. These types of buildings present an asset and typically are built not to fail under wind loadings. The increase in a building's height results in increased flexibility, which can lead to significant vibrations, especially at top floors. Such oscillations can magnify the overall loads and can be annoying to the top floors' occupants. This paper shows that increased stiffness in high-rise buildings may not be a feasible solution and may not be used for the design for comfort and serviceability. High-rise buildings are unique, and a vibration control system for a certain building may not be suitable for another. Even for the same building, its behavior in the two lateral directions can be different. For this reason, the current study addresses the application of hybrid tuned mass and magneto-rheological (TM/MR) dampers that can work for such types of buildings. The proposed control scheme shows its effectiveness in reducing floors' accelerations for both comfort and serviceability concerns. Also, a dissipative analysis carried out shows that the MR dampers are working within the possible range of optimum performance. In addition, the design loads are dramatically reduced, creating more resilient and sustainable buildings. The purpose of this paper is to stimulate, shape, and communicate ideas for emerging control technologies that are essential for solving wind related problems in high-rise buildings, with the objective to build the more resilient and sustainable infrastructure and to optimally retrofit existing structures.

FlexRay is a high-speed communications protocol with high flexibility and reliability. It was devised by automotive manufacturers and semiconductor vendors and implemented as on vehicle LAN protocol using x-by-wire systems. FlexRay provides a high speed serial communication, time triggered bus and fault tolerant communication between electronic devices for automotive applications. In this paper, we first design the FlexRay communication controller, bus guardian protocol specification and function parts using SDL (Specification and Description Language). Then, the system is re-designed using Verilog HDL based on the SDL source. The FlexRay system was synthesized using Samsung $0.35{\mu}m$ technology. It is shown that the designed system can operate in the frequency range above 76 MHz. In addition, to show the validity of the designed FlexRay system, the FlexRay system is combined with automobile advance alarm system in vehicle applications. The FlexRay system is implemented using ALTERA Excalibur ARM EPXA4F672C3. It is shown that the implemented system operates successfully.

Information and communication technologies(ICT) allow and force people to work anywhere, anytime using remote databases and application systems available in real-time twenty four hours a day and seven days a week. With the real time nature of ICT, individual work is becoming more and more fragmented. Instead of working on a similar task repeatedly, individuals are required to respond to e-mails and inquiries through social networks, work on planning documents, work on presentation documents, work on spreadsheets, input necessary data on company databases, generate necessary reports from the database, run teleconference, etc., all maybe in a day's work. Work fragmentation may impact negatively on productivity as the flow is interrupted, but it may increase the productivity by allowing people to handle multiple tasks in a shorter time period. This study explores the types of work fragmentation and their characteristics. An online survey was administered to collect data about work fragmentation and work characteristics including autonomy, complexity, flexibility, usage of ICT, etc. 300 cases were used in the analysis. Analysis of k-mean cluster indicated four different types of work fragmentation: concentrated, temporally distributed, spatially distributed, and fully fragmented.

In order to develop the environmental-friendly new materials based on soybean protein which is plantable macromolecule, thermal characteristics of the soybean protein resin (SPI) modified by plasticizers (1,3-propandiol, glycerol) and cross linking agents (glutaraldehyde, epichlorohydrin, glyoxal, urea) were analyzed by TGA. Mechanical properties of modified SPI were investigated and fracture was observed by SEM. As the result, flexibility of SPI film was increased by adding plasticizers; 1,3-propandiol and glycerol. Plasticization effect of glycerol was relatively greater than that of 1,3-propandiol. With the application of crosslinking agents (glycerol, epichlorohydrin and glyoxal), strength and thermal stability of SPI increased with their content. On the other hand, in case of addition of urea, thermal stability of SPI decreased and its strength was reduced because cross-linking between urea and SPI was somewhat difficult. Fracture surfaces and domain interfaces of the modified SPI resins were observed with SEM.
