Construction companies are trying to apply process management to their business to improve efficiency in business circumstance of high competition and globalization. Since 1990s, construction firms adopted process management to improve internal and external business structure based on process. It however has a few improvement functions. In addition, business support systems for business process efficiency improvement were developed, but separation between business process and IT system occurred because it focused on function-based individual construction and data input/output. To solve this problem, this study proposed business process and IT integration model for supporting user to use business information and system based on visualized business process and improving use of previous business support system. Business efficiency is expected to be improved with this model which based on integration required business condition(stakeholder, business data, functions of business supporting system). This study developved process model, architecture, and BPA of whole construction management business. According to BPA, it analyzed business process stakeholder, detail activities, and input-output data. And also it examined 12 main business supporting system of Korean construction firms. Based on analyzed data, this study developed business process supporting integration model based on business process through PDCA and CRUD analysis.

It has been known that health industry clusters promote economy of a nation in a macro view and make growth and development of individual firm. As a result, Korean health industry has been grown to play a role of making a high value added in Kwangkyo, Daedeok, Wonju, and Songdo. Using 156 firms locating in health industry clusters such as Kwangkyo, Daedeok, Wonju, and Songdo in increasing value added, this study investigated the structural relationships among R&D resources, R&D collaboration, policy support, and operational performance. All hypotheses, except a hypothesis for the effect R&D resources on operational performance, are reported to be statistically significant. In other words, the positive effect of R&D resources on policy support is reported. And policy support and R&D collaboration positively affect operational performance, and also the positive effect of policy support on R&D collaboration is reported. From the empirical results, we can know that policy support and R&D collaboration are the crucial factors to promote operational performance of the firms locating in Korean health industry clusters. It is important that this study has been investigated with the firms of health industry developing economy of a nation.

This study is to research the comprehensive recognition of male elderly about the sex life in old age. We collected data through face to face interview after obtaining the consents of 13 male elderly over 65 years old who reside in Kimhae Gyeongnam and Busan. The result of study showed that the sexual recognition of male elderly participants include the core concept of , , < the sex with restriction> and . In other words, the male elderly recognized the sexual life of old age as a natural and instinctive thing, the restrictions still exist including the negative recognition of family and surrounding people and diseases but it is found that the improvement of social recognition about sexual desire, the sex education and aggressive support for the various solutions are required. As the sexual awareness of the elderly is the comprehensive and broad study, the amalgamative and integrated study should be continued in the various fields. Through this, we tried to suggest the basic documents to the effective and differentiated individual sex consultation based on the empirical characteristics and desire of male elderly, and customized sex education and the development of local society program.

In this paper a web-based real-time education system, which is able to support education through multimedia, is suggested for the expansion of learner's creative ability in the school. This system is designed so that it can support three things: 1) a real time interaction between instructors and learners, 2) individual learning through such an interaction, and 3) a coercive distribution of display by instructions for preventing the deviation of learners from learning. Also, this system, which UML is applied to, makes efficient interaction possible through the module for the real-time exchange and management of messages even in the multi-user environment. Through this system, not only the simulation by learners can be made for experiments and practices, but also Questions and respondence can be supported on the procedure of experiments and the analysis of their results. This system is built on constructivism, and aimed at helping the learning progress and knowledge formation of learners.

The fact that the limits of information recency, diversity, and usability are mainly caused by the supply oriented geospatial data and service development is commonly recognized. It is recently tried to overcome the limits by facilitating user experience and VGI(Volunteered Geographic Information) in several geospatial web services. This study suggests conceptual architecture and service scenario for geospatial collaborative platform prototype through review and examination of previous researches. The prototype, composed of 4 unit modules: 3D POI Creation Module, 3D POI Application Module, 3D POI/Event Management Module, 3D POI/Event Monitoring Module, provides the capability of collaboratively dealing with geospatial work. The suggested service scenario is demonstrated by developing prototype for the service modules.

Elementary schools and middle schools currently manage their student data by using the education administration system. One of its sub-systems called 'the academic affairs support system' is especially dedicated to handle school and academic affairs data. By allowing simple data search and statistical data calculations, it helps teachers easily integrate and manage education information resources. However, it is not easy for teachers to analyze the correlations among student data. In this paper, we showed by examples that a lot of meaningful information can be extracted by analyzing the relations among student data. Based on the results, we designed and implemented SIMS as a tool to provide teachers with such services. SIMS makes use of Association Rules for data correlation analyses. SIMS can be used in connection with the academic affairs support system, and is much easier to use than previously developed commercial products for similar services.

An SNS(Social Network Service) is an online service that supports an effective way to share information over virtual communities. Recently, as SNSs such as Twitter, Facebook, and Me2day are getting bigger, the purposes of using popular SNSs are expanded to broadcastings, politics, marketings and so on. In this paper, we propose an API to integrate and manage open APIs for various SNSs, presenting a library as an implementation of the proposed API. Also, utilizing the developed library, a smartphone application is provided which supports integrated management of popular SNSs and personal schedules. Using the library, developers can reduce costs when they need to implement specific functions for managing various SNSs. With the developed application, we can read and write to/from the related SNSs on same screen, automatically reminding our schedule and sharing the schedule with friends over the SNSs.

The PSP (Personal Software Process) is developed to help developers make high-quality products through improving their personal process. With consistent measurement and analysis activity that the PSP suggests, developers can identify process deficiencies and make reliable estimates on effort and quality. However, due to the high-overhead and context-switching problem of manual data recording, developers have difficulties in collecting reliable data, which can lead wrong analysis results. On the other hand, the paper-based process guides of the PSP are inconvenient to navigate its process information and difficult to attach additional information. In this paper, we introduce a PSP supporting tool developed to handle these problems. The tool provides automated data collection facilities to help acquire reliable data, an EPG (Electronic Process Guide) for the PSP to provide easy access and navigation of the process information, and an experience repository to store development experience as additional information about the process.

DiffServ supports aggregated traffic classes to provide various QoS to different classes of traffics. However, current DiffServ specifications do not have a complete QoS management framework. It is possible to lead to serious QoS violations without a QoS management support. From this reasoning, a QoS management system that can manage differentiated QoS provisioning is required. This paper proposes and implements a policy-based QoS management platform for differentiated services networks, which specifies QoS policies to guarantee dynamic QoS requirements. The implementation of the proposed platform is built on W framework and uses XML to represent and validate high-level QoS policies. High-level QoS policies are represented as valid XML documents and are mapped into Em beans of the EJB-based policy server of the platform. The policy distribution and the QoS monitoring are processed using SNMP.

An wired ship area network has functionality of remote control and autonomous management of various sensors and instruments embedded or boarded in a ship. For such environment, the DiffServ (Differentiated Services) realizes that the high-speed real-time flow with the higher priority has the guaranteed minimum data rate and is delivered faster. As a result of this DiffServ effect, the intelligent Ship Area Networks can be implemented. In this paper, an packet drop technique is proposed to outperform the previous RIO (RED In and Out) drop mechanism for DiffServ in ship area networks. the proposed packet drop technique does not manage the individual flows and divides them into several flow groups according to a criterion. And it guarantees the fairness between individual flows in the same QoS class through the group-based control. In simulation results of the proposed packet drop technique, the link utilization decreases than RIO. But it guarantees more data rates to DiffServ flows passing multiple bottleneck links.
