In present, KTX's wheel is worn inevitably according to the interaction with rail in service. It was analyzed by wearing type, damage type and wheel reprofiling cycle on the running surface. As a result, damage on the running surface is main cause to reprofile the wheel. Wearing type of wheel is normal and it hasn't reprofiled according to normal wheel wear. As a follow-up result of the whee] defects on the running surface, if the defects size is well managed by periodical inspection, it would be efficient to increase the wheel life.

Academic libraries need to support effectively cyber education which should be managed successfully. When the information materials and library services for distance learners are supported efficiently, they can maximize learning effects. This study explored the role and function of academic libraries that seek to support cyber education successfully through previous foreign studies and presented the elements of the librarian, library service, digital library, library administration and policy that academic libraries must consider to support cyber education successfully.

Power telecommunication networks is being increased rapidly in that expansion of power plant according to the growth of electric power supply. The requirement of power plant operation & office automation make it to complex and confusing to operate. So, for the sake of correspond to the change, it is necessary that telecommunication network should be high reliable and managed effectively. In this paper, we suggest total reliability evaluation models for power telecommunication network which is based on the QOS(quality of service) standardization techniques recommanded by ITU-T.

Oil Field Geographical Information System (OFGIS) manages multiple spatial data, attribute data, and topographic data, which include almost every kind of ground info rmation and underground information. Subsystems managed by OFGIS include petroleum exploration subsystem (PESS), petroleum development and engineering subsystem (PDESS), petrochemical subsystem (PCSS), petroleum storage and transportation subsystem (PSTSS), petroleum sale subsystem (PSSS), etc. A basic OFGIS framework consists of oil field infrastructure coverage (OFIC), oil field specialized information coverage (OFSIC) and oil field synthesis and decision service coverage (OFSDSC). Basic function of OFGIS includes database management, geographic information management, spatial information processing and application.

One case of anatomically corrected malposition of the great arteries was managed at department of cardiothoracic surgery, Chungnam National University Hospital at May, 1984. Anatomically corrected malposition of the great arteries was an extremely rare congenital heart disease. Only 21 cases were reported in English literatures. If there are no associated cardiac disease, the patient will have normal life span. This 39 year old man had suffered from exertional dyspnea for 6 years. He had carried out normal military service as a sergeant for 8 years, and his life was not restricted before this episode. He had operated under diagnosis of mitral stenoinsufficiency & tricuspid regurgitation but died because of lower cardiac output.,br> At autopsy, the great arteries were malpositioned but viscera and lung were normal position and picture. The aortic valve was located left and anterior to the pulmonic valve and there are bilateral conus in this anatomically corrected malposition of the great arteries. The coronary arteries were normal distribution.

In this paper, when the power equipment, which is based on RFID, is managed, it is reviewed the performance of RFID frequency recognition and its scheme is required to manage status information efficiently. The proposed paper is studied for optimization of recognition performance, when tags are attached the power equipment & major components, to diagnosis failure status of power equipment in monitoring service. The results of paper is valuable applying environment of power equipment.

This study aimed to provide preliminary data for the improvement of the tree doctor qualification test (first written test), which was newly created by enforcing the Forest Protection Act on June 28, 2018., The high demand for system improvement accelerated this study. The results were analyzeds through literature and questionnaire surveys. Writing test questions and the license of the tree doctor qualification exam are currently managed by the Korea Forestry Research Institute, and it is deemed that the test should be entrusted to Human Resources Development Service of Korea for fair and transparent management. Additionally, the plan for the improvement of the subject-wise scope of examination questions writing, difficulty of test questions, and acceptance rate of the first test should be prepared after public hearings or seminars related to the examination questions.

Korea Ginseng Corporation is a global ginseng company, owning one of the most leading brands in Korea, CheongKwanJang. Although Korea Ginseng Corporation was an undoubted market leader in the red ginseng market, it faced a new challenge in 2012 due to the changes in market environment. In order to keep its market leadership in a saturated and competitive market, the company decided to extend its product lines alongside the launches of new brands. In this article, the authors demonstrate the development process of the company's brand portfolio strategy to reveal how the company turned CheongKwanJang into a mega-brand. Also, this paper explores the impact of CheongKwanJang's reputation on new brands, thereby illustrating how the company successfully managed to introduce new products outside of the red ginseng category, ranging from organic food to a pet food market.

This research focuses on processing unstructured data efficiently, containing various formulas in document processing and management regarding the terms and rules of domestic insurance documents using text mining techniques. Through parsing and compilation technology, document context, content, constants, and variables are automatically separated, and errors are verified in order of the document and logic to improve document accuracy accordingly. Through document debugging technology, errors in the document are identified in real time. Furthermore, it is necessary to predict the changes that intelligent document processing will bring to document management work, in particular, the impact on documents and utilization tasks that are double managed due to various formulas and prepare necessary capabilities in the future.

In this paper, we address the problem of how to replace huffers in multimedia database systems with time-varying skewed data access. The access pattern in the multimedia database system to support audio-on-demand and video-on-demand services is generally skewed with a few popular objects. In addition the access pattem of the skewed objects has a time-varying property. In such situations, our analysis indicates that conventional LRU(least Recently Used) and LFU(Least Frequently Used) schemes for buffer replacement algorithm(ABRN:Adaptive Buffer Replacement using Neural suited. We propose a new buffer replacement algorithm(ABRN:Adaptive Buffer Replacement using Neural Networks)using a neural network for multimedia database systems with time-varying skewed data access. The major role of our neural network classifies multimedia objects into two classes:a hot set frequently accessed with great popularity and a cold set randomly accessed with low populsrity. For the classification, the inter-arrival time values of sample objects are employed to train the neural network.Our algorithm partitions buffers into two regions to combine the best roperties of LRU and LFU.One region, which contains the 핫셋 objects, is managed by LFU replacement and the other region , which contains the cold set objects , is managed by LRUreplacement.We performed simulation experiments in an actual environment with time-varying skewed data accsee to compare our algorithm to LRU, LFU, and LRU-k which is a variation of LRU. Simulation resuults indicate that our proposed algorthm provides better performance as compared to the other algorithms. Good performance of the neural network-based replacement scheme means that this new approach can be also suited as an alternative to the existing page replacement and prefetching algorithms in virtual memory systems.
