  • This paper describes implementation contents contents of manual/automatic complex redundancy control mothod for control of a modulation system of a Paging earth station in redundancy stracture. The existed redundancy control method usually is a automatic local control method in which the redundancy switching, including display or alarm beeping through operation of display devices or audio devices, is performed by the co-action of components or modules when the abnormal status is occurred in a modulation system. However, this method introduced in here is designed to enable use of three control modes;1) Manual mode by an operator, 2) Auto-remote mode by the Network Maagement System, through implementation of the redundancy control system composed of the redundancy control board and the redundancy switching circuit.

  • The interest about sustainable development of airport operation field has been increased as the aviation industry has been gradually developed and the influence to the neighboring area of airport has been increased. International organization and airport operator have issued a guidance manual with regard to the sustainability specialized in airport by adopting environment friendly rating system and developing a variety of sustainable practices. In this study, the guideline of sustainability manual appropriate to the local airports will be suggested by reviewing a variety of reference documents issued from foreign airport operators.

  • The construction of green building has distinct charicteristics by work classification by applying green technologies. Thus if the new technologies are applied to construction, unskiiled worker can experience construction time delay, reconstruction occurrence and quality decrease because of mistakes during the construction and work progress. For this background, we establish the work progress manual to secure quality and performance during the construction phase of green building and provide method to be used in the construction sight operation.

  • This study aims at presenting the scheme for operation of reading classroom programs through analysis of present situation of reading education programs in public libraries. To collect data for analyzing the present situation, the plan and its report in relation to operation of reading classroom programs in 22 public libraries, implemented in winter, 2007, were used. In addition, questionnaire surveys to the librarians in charge of reading classroom programs in 22 public libraries were also carried out. As the remedies to problems of the program operations were presented in identification and participation, contents of education, manpower, reeducation of librarians, budgets, facilities, and work structure. The scheme for operation of reading classroom programs for keeping the characteristics and tradition of public libraries needs to develop an operation manual for reading classroom programs.

  • In the automatic operation of an urban rail vehicle, a conventional PID control algorithm is applied to run the vehicle between stations within time limit and jerk limit. But the energy consumption in the automatic operation is much higher than in the manual operation. In this study, the optimal control algorithm for automatic operation is proposed to minimize energy consumption, which satisfies automatic operation for the urban rail vehicle, compared with the conventional PID control algorithm.

  • Purpose: Axillary osmidrosis is caused by excessive apocrine gland secretion, which causes an unpleasant odor. Axillary osmidrosis causes difficulty in social activities and personal handicap. We studied the long term follow up results of our surgical procedures and sought to find a best surgical treatment methods. Methods: From January 1991 to December 2006, a total of 1864 patients(587 men, 1277 women) had been treated with this procedure for axillary osmidrosis and hyperhidrosis. Follow up periods varied from 10 to 15 years. We used the subdermal excision technique, using two small incisions over the axilary folds and using a Kawata dissector(instrumental shaving) and additional manual subdermal excision(manual shaving). Results: Among the total patients, 782 patients were followed up. Except a pure hyperhidrosis patients, 759 osmidrosis patients was included. 588 patients(77.4%) had a good results, 148 patients(19.5%) had a moderate results and 23 patients(3.1%) had a recurrence. Complication developed in 189 patients(10.1%): hematoma or seroma in 25 patients, wound dehiscence in 86 patients, partial skin necrosis in 45 patients, and infection in 28 patients. Conclusion: We conclude that our method has several advantages such as 1) short operation time, 2) minimal scaring, 3) lower complication rates, 4) high satisfactory rates.

  • Objectives : The aim of this study was to report the improvements in pain that a woman experienced after receiving Korean medicine treatments for the pain associated with core decompression surgery due to avascular necrosis (AVN) of both femur heads. Methods : The patient was diagnosed as having AVN in both femur heads and underwent core decompression surgery. After operation, she had pain on her right inguinal region and her range of motion (ROM) was restricted. She was treated with Korean medicine including, herbal medicine, acupuncture, Chuna Manual Therapy and bee venom acupuncture (BV). This study was measured by using the Visual Analogue Scale (VAS) and the ROM scale. Results : After conservative treatment, the patient's pain was reduced and ROM was increased. Daily living quality had improved. Conclusions : In this case, Korean conservative medicine therapy with Chuna Manual Therapy had a positive effect on the symptoms after core decompression surgery due to avascular necrosis of the femur head.

  • The Project of Jordan Research and Training Reactor (JRTR) officially launched in Aug. 2010. JRTR is the first made-in-Korea nuclear system to be built abroad by year 2015, and Korea Atomic Energy Research Institute (KAERI) is responsible for the design of major systems including the reactor core. While the PDCS (Project Document Control System) being operated by EPC company controls all the documents of the whole Project, KAERI is supposed to have its own system for KAERI documents. Meeting such a need; KAERI has implemented a document control for the JRTR Project into already existing ANSIM (KAERI Advanced Nuclear Safety Information Management) system. The documents of JRTR project to be controlled are defined in the PPM (Project Procedures Manual), QAP (Quality Assurance Procedure) and PEP (Project Execution Program). The ANSIM consists of the document management holder, document container holder and organization management holder. The document management holder, which is the most important part of ANSIM-JRTR, consists of the DDA (Document Distribution for Agreement), IOC (Inter-office Correspondence), PM Memo. (Project Manager Memorandum) and cover sheets of design documents. Other materials such as meeting minutes, sub-department materials and design information materials are stored in an independent COP (Community of Practice). This established computerized document control system, ANSIM, could lessen a burden for project management team and enhance the productivity as well.

  • A manipulator with 3 degrees of freedom is developed to automate operation of 60 ton pressing process. The pneumatically actuated manipulator is controlled by a programmable controller. Four seconds of cycle time which is faster than manual operation is achieved. Though the flexible feed mechanism, the system can accammodate any size of workpieces between 80*80 and 200*200 under 1 kg of weight.

  • Generally Jar-Test is available to determine the coagulant dosage rate. Disadventages associated with Jar-Test are that regular samples have to be taken requiring manual intervention and the limitation to feedback control. To deal with this difficulty, determined optimized dosage rates of coagulant to investigates the union operation method of the statistical equation which uses the multi-regression method and the SCD.
