Using information mapping methodology we will discover which of the multitude of information sources, services and systems used by corporation are actually resources and which are less important, redundant, or unnecessary. The discovery process of information resources will illuminate problems and opportunities related corporation's strengths and weeknesses in information quality, accessibility, performance, use, and effectiveness.

The main purpose of the study is to determine the key aspects of Agile management as the basis of a management system in the context of globalization. The research methodology includes several scientific and theoretical methods that have achieved this goal. Adaptation of enterprises engaged in the development, production, and sale of innovative products to constant and rapid changes in the external environment requires managers to apply appropriate management methods. The use of Agile management in the management of innovation processes can speed up their implementation, minimize and optimize the use of resources, time, and effort of staff, can increase customer and customer satisfaction with the end result and, consequently, improve the company's competitive position in the market. The results of the study identified key aspects of the application of Agile management in the management system in the context of globalization.

This study was aimed at applying the IUCN category system to the Baekdudaegan Protected Area. A classification key was developed to apply the system to the overlapped designated protected areas inside of Baekdudaegan Protected Area. Korea national parks and forests managers' and experts' opinions were collected and they all agreed to the use of multiple classification in Baekdudaegan Protected Area. For example, the type of natural forests among the Forest Genetic Resources Reserves was classified to be IUCN Category Ia while other types of Forest Genetic Resources Reserve was classified to be Category IV. And the Protected Forest Landscape was classified to be Category V while the other types of protected forests were classified to be Category VI. The study suggests the need of classification of forest protected areas including Baekdudaegan Protected Area using IUCN system accompanying with protected areas management effectiveness evaluation.

Existing human resources dispatch systems face various limits for managing increasing information derived from the work-place as it required much time managing the basic data created at the work-place and the data input methods are complicated. This study focuses on how to solve the above mentioned problems by utilizing the cellular phone system, which provides vital connection between the organizations using the dispatched human resources and the resources. The study offers building of a necessary work history data base and its management through development of a mobile human resources dispatch system. In order to optimally place the given resources, the system utilizes deductive analytical process. Utilizing the intelligent, deductive analytical process in properly planning the placing of the right human resources to do the job will result satisfaction in human resources dispatch and management.

In industrial fields like big factories, efficient management of resources is critical in terms of time and expense. So, inefficient management of resources leads to additional costs. Nevertheless, in many cases, there is no proper system to manage resources. This study proposes a system to manage and track large-scale resources efficiently. We attached Bluetooth 5.0-based beacons to our target resources to track them in real time, and by saving their transportation data we can understand flows of resources. Also, we applied a diagonal survey method to estimate the location of beacons so we are able to build an efficient and accurate system. As a result, We achieve 47% more accurate results than traditional trilateration method.

The Spectrum Usage Fee System which has been introduced and enforced since 1993 has had a great role for effective use of the radio frequency resources and the promotion of radio wave industry. However, the current system has been criticized due to several drawbacks. For example, broadcasting stations and national institutions are exempted whereas the overdue utility rate on some frequency has been imposed. So there has been rising the questions on whether the principles of fair imposition are broken. Another problem regarding the current system is that how to calculate the fee is too much complicated, and it needs to be revised into a simpler and clearer formulation. In this regard, this study intends to propose a new calculation framework for the radio spectrum usage fee and then prove its validity empirically on the basis of real data gathered from MIC and focus group interview.

There use many production management systems for increasing productivity, minimizing inventory, keeping due dates and maximizing use of resources. MRP, GT and JIT are popular among these systems. There use many production management systems for increasing productivity, minimizing inventory, keeping due dates and maximizing use of resources. MRP, GT and JIT are popular among these systems. In this study, we had designed mixed production system which integrated searching and grouping function of GT, purchasing function of JIT and based on MRP and developed related algorithms and applied systems. The developed system was based on appling renewed algorithms for existing MRP system. To test efficiency operated real-data but we have tested renewed algorithms using sample-data because of massive real-data.

Korean logistics industry have been focused on transportation business. However, with the expansion of the electronic commerce and on-line shopping, delivery service is now dramatically growing. Despite the expansion of logistics market, the domestic logistics industry have significant structural problems such as low productivity comparing with the advanced countries, relatively high cost and shortage of human resources and lack of professionalism of people in the industry. Logistics companies reallocate employees, use subcontractors, expand consignment and training the employees to overcome the labor shortages but it has some limits. In recognition of the importance of labor in the logistics industry, financial support and investment have increased. Logistics companies tend to hire consultants, set up logistics department or R&D center in order to establish highly productive logistics process and system so it is viewed that there will be considerable demands of human resources in the logistics industry. This study indicates implications and development direction of human resources in the logistics industry by looking into prospect and characteristic of the industry, employment status, training programs and qualification requirements.

This paper covers a series of activities including initial proposal and actual development for the performance improvement of large-scale public facility management system under the application of green IT concept, which finally produced various excellent results in the administration of expense control, human resources, and general affairs. Actual development procedure starts from the analysis required by system users with the purpose of finding cost reduction opportunities under the application of green IT concept, which is followed by a series of activities including making a proposal for performance improvement, the development of trial system and the actual application into real system. As an example of large-scale public facility management system, national qualification management system was taken in order to convert the existing individual test storage unit into on-line storage space equipped with reinforced security function, resulting in acquisition of efficient productivity and greater savings in human resources as well as general expenses. A comparison with existing system and newly developed system was made in the area of number of operators, abnormal processing, system maintenances. It proved that efficiency increased to the minimum of 2 times and to the maximum 12 times with the 5 million savings of personal storage unit.
