Recently the demand for electrical power is significantly increased due to the life improvement of customers. Correspond to the result, the transmission capacity is larger, also the fault current is significantly larger. Within the methods of limiting this fault current, the methods of using the fault current limiter is on the rise. If the Superconducting Fault Current Limiter(SFCL) is applied, then the power delivery loss doesn't exist between the plural power systems, also the fault current can be reduce. But for applying the real system, it needs to investigate the effect of SFCL before appling to real power systems. Consequently, the fault of transmission with SFCL was simulated using EMTP. It was investigated to the effect of SFCL at the 345[kV] transmission fault according to compare with the case of appling SFCL and removing SFCL.

A study was performed to identify current drug shortages, assess impact of drug shortages on public hospitals and patients, and investigate needs of pharmacists for a drug shortage list. An e-mail survey was sent to the pharmacists of 13 national public hospitals. Total 61.5% of public hospitals has 10 or fewer drugs a year in short supply. Shortages involved mood drugs, anti-tumor drugs, analgesics, antibiotics and etc. in 2012. Among them 75.0% was prescription drugs and the other 25.0% was non-prescription drugs. 79.2% was domestic products and 20.8% was imported drugs. Only 12.5% was injections. Less than 3 pharmacists usually spent within 3 hours managing one drug shortage. Since a single item for a certain medicine may raise risk of drug shortages, it's needed to consider developing manuals, laying up medicine stocks and holding plural medicines for drug shortages in public hospitals. Main information resources of drug shortages are wholesalers or manufacturers. But the information appeared to be not only inadequate but also too late for appropriate activities. A survey of pharmacists revealed that overall 84.6% of respondents were in need of the drug shortage list. They expected it to be conducted to take proper measures for the drug shortage and to improve patient healthcare outcome and convenience. This study will contribute to improving public health by promoting stable supply of drugs and repairing the information delivery system.

This paper addresses the maintenance optimization problem in multi-component systems in which parts are connected in series, carrying out several missions interspersed with scheduled finite breaks. Due to limited time or resources, maintenance actions can be only carried out on a limited set of components. The decision maker then has to decide which components to maintain to ensure a pre-specified performance level during next mission. Most of the existing models in the literature usually assume only one system and enough spare parts. However, there are situations in which maintenance is required for multiple systems of the same type. To overcome this restrictive assumption, this study optimizes the maintenance problem considering the lack of repair parts and cannibalism for many identical systems. This study presents two optimization models with different objectives to solve the problem and analyzes the results so that the decision maker can decide. The results of this study are expected to be used for the maintenance of multiple systems of the same type, such as swarm drones.

In this paper, performance of autoencoder based OFDM communication systems is compared with IEEE 802.11a Wireless Lan System (Wi-Fi). The proposed autoencoder based OFDM system is composed of the following steps. First, one sub-carrier's transmitter - channel - receiver system is created by autoencoder. Then learning process of the one sub-carrier autoencoder generates constellation map. Secondly, using the plural sub-carrier autoencoder systems, parallel bundle is configured with inserting IFFT and FFT before and after the channel to configure OFDM system. Finally, the receiver part of the OFDM communication system was updated by re-learning process for adapting channel condition such as multipath channel. For performance comparison, IEEE802.11a and the proposed autoencoder based OFDM system are compared. For channel estimation, Wi-Fi uses initial long preamble to measure channel condition. but Autoencoder needs re-learning process to create an equalizer which compensate a distortion caused by the transmission channel. Therefore, this autoencoder based system has basic advantage to the Wi-Fi system. For the comparison of the system, additive random noise and 2-wave and 4-wave multipaths are assumed in the transmission path with no inter-symbol interference. A simulation was performed to compare the conventional type and the autoencoder. As a result of the simulation, the autoencoder properly generated automatic constellations with QPSK, 16QAM, and 64QAM. In the previous simulation, the received data was relearned, thus the performance was poor, but the performance improved by making the initial value of reception a random number. A function equivalent to an equalizer for multipath channels has been realized in OFDM systems. As a future task, there is not include error correction at this time, we plan to make further improvements by incorporating error correction in the future.

In July 1989, Korea had achieved the national medical insurance system comprehensively covering the whole population since its inception of 12 years before, and subsequently the plural medical insurers had integrated to the unique health insurer system in July 2000. But there yet remain some problems to be improved under low contributions rates and poor benefit packages, especially the shortage of assuring beneficiaries' rights. The Health Insurance Appeal System is composed of a two-tiered system of committee. The Formal Objection Committees built in the National Health Insurance Corporation and in the Health Insurance Review Agency respectively examine the formal objections to the decisions of the Corporation, or the Review Agency. And the Dispute Mediation Committee built under the command of the Minister of Health and Welfare reviews the protests against the decisions on the formal objections by each Formal Objection Committee. To cope with the appellant in relation to the administration on the qualification of the insureds, contributions, and insurance benefits etc, is found to be unsatisfactory. There's the reason of poor function on right-relief caused by the loose composition of the Appeal Committee, the deficit of people's recognition and P.R., the lack of professional manpower and the Committee's independency, and time lag in making decisions and so on. Consequently the Appeal System should be improved to secure the rights-relief function, to empower the professionalism of the Appeal Committee, to strengthen P.R. for the beneficiaries, to build up the staff's proficiency through training, and to develop the quality of administrative services.

The purpose of this study is to identify the influence of the change on librarian number of local governments on the lump-sum personnel expenditure system. Data were collected and analyzed from the Enhanced local laws and regulations information system and local government home pages of 15 local governments where opened more than two public libraries from 2008 to 2010. Results show that the number of 15 government employees was increased but the number of librarian was slightly increased. Also, the number of administrative positions was increased using plural series position system. It shows that the number of librarian can be increased under the lump-sum personnel expenditure system.

Objective: Various controlled vocabulary such as thesaurus and classification make us to reuse and share effectively by defining different concept and linking terms each other. The UMLS(Unified Medical Language System) is one of the most universal medical terminology systems. It is needed various methods to share and reuse information of traditional Korean medicine. We will research on method that adopt SUI of the UMLS(that is de facto standard in medical terminology system) in traditional Korean medical terminology. Method: We described major problems and applying process when we tried to add traditional Korean medicine in the part of meridian into the UMLS metathesaurus. Comparing western medical terms and traditional Korean medical terms for applying UMLS metathesaurus, there is not only many consistency, but also differences. Result: We confirmed what is the differences and consistency between western medical terms and traditional Korean medical terms. And then reviewed methods that apply the CUI, LUI, SUI in traditional Korean medical terms. Traditional Korean medical terms are not discriminated by singular or plural string. In addition, traditional Korean medical terms have vary string by initial law: the law of initial sound of a syllable. Character is described with Korean, traditional Chinese, modern Chinese, etc. According to meaning, language, initial law, SUI has a distinct value respectively. Conclusion: There are many differences to apply the UMLS between western medical terms and traditional Korean medical terms. For the better implementation to traditional Korean medicine into the UMLS, further research is needed in standardization and classification of traditional Korean medical terms, medical information system, etc. We hope this study helps the implementation UMLS, EHR, knowledge based system in Oriental medicine in the future.

Purpose: This study was to develop an online 'alternative therapy and health promotion' class for university students and to evaluate its changes. Method: The online class was developed based on the Instructional Systems Development(ISD) model and model of Web-Based Instruction(WBI) developmental process. This was a quasi-experimental, one group pretest-posttest design. The subjects of this study were 130 students in 3 universities, and they were provided the cyber class for 16 weeks. Data was analyzed by descriptive and plural answer statistics, and paired t-test. Results: The cyber class was developed in five steps : analysis, design, data collection and reconstruction, programing and publishing, and evaluation. The results of program evaluation were positive, which included learning 3.47. system 3.57, and learning satisfaction 3.64 on the scale of 5. The posttest scores of cognition and reliability of alternative therapy were higher than pretest scores. The posttest score of health promoting lifestyle(t=-5.051, p=.000) and perceived health status(t=2.979, p=.003) were significantly higher than those of the pretest. Conclusion: These results suggest that the cyber class is a positive method in increasing a cognition, reliability of alternative therapy, and is effective to improve a health promotion lifestyle and perceived health status for the university students.

It is well-known that a neural network with cyclic connections generates plural limit cycles, thus, being used as a memory system for storing large number of dynamic information. In this paper, a continuous-time cyclic connection neural network was built so that each neuron is connected only to its nearest neurons with binary synaptic weights of ${\pm}1$. The type and the number of limit cycles generated by such network has also been demonstrated through simulation. In particular, the effect of chaos signal for transition between limit cycles has been tested. Furthermore, it is evaluated whether the chaotic noise is more effective than random noise in the process of the dynamical neural networks.
