In this paper, we suggest the roles of IPP (Industry Professional Practice) professor that are necessary for efficient and systematic operation and management of IPP system, which has been implemented by KOREATECH recently under the goal of nurturing industry-oriented talents with practical skills, based on the analysis of actual operational practices of advanced overseas universities and the IPP experiences for 2 years. The roles of IPP professor are largely divided into the following three: IPP manager; student career counselor; educator of IPP educational program. During the initial stage of IPP system, the role of IPP manager is most significant. However, as the system is systematically managed and operated, the role of IPP manager gradually decreases, and the role of career counselor becomes more important. Since IPP system is an educational program that gives credits, IPP professor should also perform the role of educator, including designing experiential learning curriculum and evaluation on educational goal accomplishment.

Currently, the quality management, safety management and environment management of domestic construction work does not form a infrastructure for integrated control which have been developed according to the unique characteristics based on respective the law. In other words, the quality manager and safety manager of human resources is set to a legal arrangement personnel, but environment manager of human resources is not. In addition, quality management standard is to perform the work to PDCA(Plan-Do-Check-Action) system which is reflected in all of the requirements of KS A ISO 9001 standard, but safety management plan and hazard harmfulness prevention plan are not properly reflected P(Plan), C(Check) and A(Action) system and focusing on only 4 section Do(D) in KOSHA 18001 standard requirement. Moreover environmental management plan is not even established requirement. Through examining the operation practices of an advanced nation prior to building the integrated control standard for construction work qualify safety.environment, the possibility of applying domestic is reviewed, and then this study is going to research the operation practices of Singapore.

With respect to the cause of asymmetric cost behavior, there are two streams of the literature. One stream focused on effect of managerial expectation and the other explained using agency system. In this study, we aim to investigate the determinants of asymmetric cost behavior in these streams. We first examine the impact of managerial overconfidence and optimistic bias on asymmetric cost. We also examine ownership ratio as a proxy of the quality of corporate governance effects on asymmetric cost. The results are as follows. First, firms have the anti-sticky asymmetric cost behavior. Second, we find that the firms with managerial optimistic bias mitigate the degree of asymmetric cost. This finding implies that managerial optimism is a factor that alters asymmetric cost behavior. Third, the degree of asymmetric cost is weaker in case of firms with higher manager's ownership. This result provides an important empirical evidence for understanding the role of corporate governance in cost behavior.

Requirement level regarding processing and managing real-time datastream in an ubiquitous environment is increased. Especially, due to the unbounded, high frequency and real-time characteristics of datastream, development of specialized stroge manager for DSMS is necessary to process such datastream. Existing DSMS, e.g. Coral8, can support datastream processing but it is not scalable and cannot perform well when handling large-volume real-time datastream, e.g. 100 thousand over per second. In the case of Oracle10g, which is generally used in related field, it supports storing and management processing. However, it does not support real-time datastream processing. In this paper, we propose specialized storage manager of DSMS for real-time compressed storing on semiconductor or LCD production facility of Samsung electronics, Hynix and HP. Hynix and HP. This paper describes the proposed system architecture and major components and show better performance of the proposed system compared with similar systems in the experiment section.

In this paper, we investigated electric safety manager's PL recognition and accident occurrence of electric power facilities(power cable, transformer, circuit breaker) in electric installation for private use. The target of questionnaire survey is 450 electric installations for private use, 154 responded the questionnaire among these and it occupied 35.8%. Most of receiving voltage were 22.900kV. The questionnaire survey says that 58% of electric safety manager knew well about PL contents and 42% of them did not recognize about PL contents, About the PL application of electrical facility accidents, 82.4% of them must applied PL law, 5.8% of them did not need the PL law. Reason of PL application occupied 64% for stability of electrical facility and product, 19% for prevention of same accident. The accident of transformer occupied most and the power cable accident were much next. The questionnaire survey results, electric safety managers are interested in PL content. thev expected necessity of PL application about electrical accident strongly.

Proxy Mobile IPv6 (PMIPv6) is a network-based mobility support protocol and it does not require Mobile Nodes (MNs) to be involved in the mobility support signaling. In the case when multiple interfaces are active in an MN simultaneously, each data flow can be dynamically allocated to and redirected between different access networks to adapt to the dynamically changing network status and to balance the workload. Such a flow redistribution control is called "flow mobility". In the existing PMIPv6-based flow mobility support, although the MN's logical interface can solve the well-known problems of flow mobility in a heterogeneous network, some missing procedures, such as an MN-derived flow handover, make PMIPv6-based flow mobility incomplete. In this paper, an enhanced flow mobility support is proposed for actualizing the flow mobility support in PMIPv6. The proposed scheme is also based on the MN's logical interface, which hides the physical interfaces from the network layer and above. As new functional modules, the flow interface manager is placed at the MN's logical interface and the flow binding manager in the Local Mobility Anchor (LMA) is paired with the MN's flow interface manager. They manage the flow bindings, and select the proper access technology to send packets. In this paper, we provide the complete flow mobility procedures which begin with the following three different triggering cases: the MN's new connection/disconnection, the LMA's decision, and the MN's request. Simulation using the ns-3 network simulator is performed to verify the proposed procedures and we show the network throughput variation caused by the network offload using the proposed procedures.

Recently, the number and scale of projects being carried out within the enterprise are increasing. Accordingly, many companies are competitively introducing a Project Management Office (PMO) to efficiently manage these projects, allocate resources, and effectively link the projects and corporate strategies. However, the project manager who directly manages the project wants to receive support from the PMO in many areas for successful project management, but the project manager does not like to be interfered with by the PMO. On the other hand, the PMO may not be able to satisfy all the requirements of each PM as PMO oversees the entire project with limited resources. In addition, since the PMO must monitor and control the project and support the project according to the priorities of each project, conflicts with each PM can be formed. Therefore, in this study, based on the case of a company, the difference between the perceptions of PMs and PMOs about the importance of the required roles of PMOs is to be examined. As a result of the study, it was confirmed that the core functions and sub-functions of PMO, which PMO members and PMs consider important, are different. It was identified that the PMs valued the PMO function that would be helpful for their successful project execution. On the other hand, PMO members revealed that they had a relatively high priority for the roles to monitor and control project performance for which they were directly responsible.

The goal of this study is to find ways to improve the open access publication support service platform through the usability evaluation of the publishing manager interface among the AccessON journal repository interfaces, which is an open access publication support service platform. Various documents and cases related to open access publishing and usability evaluation in order to answer three research questions: collection of user experience responses of interface, extraction of issues and improvement points, and analysis and derivation of suggestions for other open access publication support service platforms. Responses to the experience of using the publishing manager interface were collected through surveys and focus group interviews. Combining this, it was possible to present the results of the usability evaluation of the AccessON journal repository interface through various numerical information. The results of the usability evaluation made it possible to propose issues and improvements to the AccessON journal repository manager interface, and finally, it was possible to derive suggestions for the open access academic publishing support service platform to be developed later.

Construction industry recognizes the necessity to manage is business from viewpoint of processes, and consider developing, evaluating and improving standard processes as important managerial target. SW-CMM provides basic framework for this process management. However, appropriate tailoring and adjustment are essential for SW-CMM concept to be applied to construction business. SW-CMM makes construction manager understand the capability of business process, based on which the priority of process improvement is judged. The capability is prescribed by common features. This paper introduces the basic frame for diagnosing construction business processes with SW-CMM, and presents the case study of analysing processes focusing on communication management.
