  • EDMS systems have been a main alternative for enterprise content management (ECM), which provide valuable functions for the effective control and management of organization-level digital contents. However, it has not been effective frequently for the purpose of integrative control of overall contents in an organization. One of reasons for this problem is that individuals usually create and store files with their own personal computers and do not move them to the central storage and control device, EDMS. Many occasions show that this situation can cause undesirable results for better management of enterprise contents. This paper introduced an approach of virtual folder which can directly connect individual computers and EDMS storage device without users' inconvenience. Adding the capacity of restricting usage of individual computer, users unavoidably and conveniently store and retrieve digital contents using EDMS server system. Several modules and implementing architecture for the virtual folder system are shown and the results of utilizing the system are explained with a case of application.

  • The purpose of this study is to draw out objective bases for selecting various applicable facilities in case of the establishment of rainwater management strategies. To do so, sixteen facilities were selected from decentralized rainwater management systems that induce rainwater infiltration and detention as well as centralized end-of-pipe type infiltration and detention facilities in local areas. With these facilities, it attempted to evaluate them in terms of sustainability, pollutant elimination, flood control capacity and costs and subsequently analyzed correlations between each characteristic. The outcomes of the analysis were as follows: First was the analysis of characteristics between decentralized rainwater management systems and end-of-pipe rainwater management systems. From the decentralized rainwater management systems, the mulden-rigolen system and grass swale at street level had the highest in the total of the four items while the totals of the underground detention tank and temporary detention site were highest in end-of-pipe rainwater management systems. After analyzing the correlation between different types of facilities and each variable, it can be said that decentralized rainwater management systems have a higher correlation than end-of-pipe rainwater management systems in terms of sustainability whereas the latter are better in flood control capacity than the former. Second, the analysis of correlation in variables of each facility is as follows: first, there is a negative correlation between sustainability value and flood control capacity value; and there is a positive correlation between flood control capability and pollutants elimination. In addition, it revealed that the higher the flood control and pollutant elimination capability the higher the facility costs. Based on these assessments, it is possible to use them as objective selection criteria for facility application in case of site development project or complex plan.

  • Weeds are one of the major constraints to crop production in organic farming systems. This paper reviews major results and techniques achieved with physical, cultural, and biological weed control and their perspectives in organic agriculture. Physical methods includes mechanical, thermal, lighting, electrocution, pneumatic, autonomous robot weeding control techniques. Cultural weed control methods includes mulching, tillage, crop rotation, cover crops and crop competition. Physical and cultural weed control techniques are especially important in organic farming crops where other weed control options are limited or not available without use of herbicides. Biological weed control includes mycoherbicides, innundative biological control, broad-spectrum biological control and allelopathy. Successful weed management in organic farming requires well managed integrated systems of mechanical control using newly developed machines, cultural control and biological control methods. Weed management decision-aid models may also needed to develop to provide greater assurance of achieving profitability and appropriate long-term weed management in organic farming in the future.

  • Process Control Systems (PCSs) or Supervisory Control and Data Acquisition (SCADA) systems have recently been added to the already wide collection of wireless sensor networks applications. The PCS/SCADA environment is somewhat more amenable to the use of heavy cryptographic mechanisms such as public key cryptography than other sensor application environments. The sensor nodes in the environment, however, are still open to devastating attacks such as node capture, which makes designing a secure key management challenging. Recently, Nilsson et al. proposed a key management scheme for PCS/SCADA, which was claimed to provide forward and backward secrecies. In this paper, we define four different types of adversaries or attackers in wireless sensor network environments in order to facilitate the evaluation of protocol strength. We then analyze Nilsson et al. 's protocol and show that it does not provide forward and backward secrecies against any type of adversary model.

  • This paper analyzes problems related to total cost changes in private investment projects, and then proposes an improvement measure for the control of cost changes within the framework of the project management, contract, human resource, project communication, cost, and time management. From the viewpoint of contract management, the basis of cost change ought to be cleared up with standardization of related provisions in the concession agreement, and potentiality of change ought to be excluded with prescription of the private investor's leading role from the design phase. Regarding human resource management, this paper proposes a standard work flow granting much sovereign rights to private parts by putting restriction on work scopes of the entrusted authority of government, and transferring the rights of assignment, contract, and control about the responsible supervisor to the concessionaire. With regard to project communication management the notification of changes on drawings and technical documents ought to be automated and the realtime database ought to be established with DMIS (Drawings & Documents Management Information System). From the cost management point of view, this thesis integrates the control of cost-change-approved items and disapproved items to one cost breakdown system, and then harmonizes the actual progress with EVMS in time management.

  • Pain management is a major issue in caring of cancer patients. Because pain management cancer patient of does not control effectively, it is important to educate reporting pain and using analgesics for having cancer patient's concerns and anxiety. The purpose of this study was to identify the effect of cancer pain management education on the pain and concerns of pain management in cancer patients. This study was a quasi-experimental as nonequivalent control pretest-post test design. The subjects of this study consisted of 50 (experimental group 25, control group 25) patients hospitalized in K university hospital in Busan. The data were collected from December 1, 2001 to April 12, 2002. The measurement tool for the concerns of pain management had used questionnaires interpretated by Kim(1999) developed by based Ward(1993) and pain nominal scale. The collected data were analyzed frequency, percentage, mean, SD, $X^2$-test, t-test, ANCOVA. The results of this study were as follows: 1. The 1st hypothesis : "The experimental group which had received the cancer pain management education were lower than the control group in the score of pain" was not supported (p>0.05). 2. The 2nd hypothesis : "The experimental group which had received the cancer pain management education were lower than the control group in concerns of pain management" was supported (F=5.285, p<0.01). In conclusion, the cancer pain management education can know what was effective to decrease in the concerns of pain management in cancer patients. Therefore, Pain Management Education must be positively utilized in clinical situation.
