An engineering design problem involving Multi-Disciplinary Analysis(MDA) generally requires a large amounts of CPU time for the entire design process, and therefore Multiple Processing System (MPS) are essential to reduce the completion time. However, when applying conventional parallel processing techniques, all of the CAE S/W required for the MDA should be installed on all the servers making up NIPS because of characteristic of MDA and it would be a great expense in CAE S/W licenses. To solve this problem, we propose a Weight-based Multiqueue Load Balancing algorithm for a heterogeneous MPS where performance of servers and CAE S/W installed on each server are different of each other. To validate the performance, a computational experiments comparing the First Come First Serve algorithm and our proposed algorithm was accomplished.

The national 2G-3G roaming is emerging as one of essential and important issues In Korea in connection with the recent granting of 3G licenses. Accustomed to the current seamless coverage and superb quality of 2G networks, many subscribers have very high expectations of an equal or better service provisioning by 3G networks. However, it is very unlikely for 3G operators to successfully build their networks as comprehensive as the current 2G networks in the beginning of network implementation and commercial launch. Therefore,3G operators are seriously considering the national 2G-3G roaming in Korea. In this paper. 1 would like to discuss and present a technical implementation scheme and problems that need to be solved fer successfully realizing the national 2G-3G roaming.

Approaches to several recent issues in the operation of nuclear power plants using computational intelligence are discussed. These issues include 1) noise analysis techniques, 2) on-line monitoring and sensor validation, 3) regularization of ill-posed surveillance and diagnostic measurements, 4) transient identification, 5) artificial intelligence-based core monitoring and diagnostic system, 6) continuous efficiency improvement of nuclear power plants, and 7) autonomous anticipatory control and intelligent-agents. Several changes to the focus of Computational Intelligence in Nuclear Engineering have occurred in the past few years. With earlier activities focusing on the development of condition monitoring and diagnostic techniques for current nuclear power plants, recent activities have focused on the implementation of those methods and the development of methods for next generation plants and space reactors. These advanced techniques are expected to become increasingly important as current generation nuclear power plants have their licenses extended to 60 years and next generation reactors are being designed to operate for extended fuel cycles (up to 25 years), with less operator oversight, and especially for nuclear plants operating in severe environments such as space or ice-bound locations.

Yeongnyeon-euisaeng (永年醫生) was a licensed Euisaeng (醫生) without time limit. Yeongnyeon-euisaeng was a member of bridging the gap between Joseon Dynasty and the Japanese colonial period in hanuigye (韓醫界). This study aims at better understanding the Yeongnyeon-euisang. In methods, several statistics have been served about Yeongnyeon-euisaeng on the basis of the Official gazette. The following facts have been found through the Official gazette. First, the time limitted licenses have been issued mixed with a permanent license. Secondly, Yeongnyeon-euisaeng lived longer than other people. Third, the residence of Yeongnyeon-euisaeng was a very high proportion in South Hamgyong Province. Fourth, Yeongnyeon-euisaeng played an important role in Korean medical doctor (韓醫師) system after the liberation. In addition, the correlation of multilateral for Yeongnyeon-euisaeng and Confucian doctor were examined. Area of the Confucian doctor decreased since the 17th century. Confucian doctor's region and position declimed during the Japanese occupation. But Confucian doctors were also culled as status of Korean medicine and Neo-Confucianism declimed.

National qualification system for SW engineering is intended to be mechanisms to assure the competence of SW professionals. Qualification system for SW engineering can be categorized as national qualification, nationally certified private qualification, and private qualifications. In this paper, we present a summary report of needs analysis for new national qualification systems, based on the survey from human resource department managers of IT companies in IT service, package SW and embedded SW industry. The survey results show that SW qualification system is appropriate for evaluation and career management, but does not provide up-to-date information concerning the technology assessment and change. Based on the result form needs analysis, we suggest the SW specialist and embedded SW specialist as new licenses in national qualification system. In addition, we also propose SW quality management engineer, systems management engineer, IT Protect management engineer, network management engineer and SW architect engineer, as new nationally certified private qualifications.

Technological innovations can be protected by patents, and patent applications are filed in various patent offices around the world including the United States Patent and Trademark Office (USPTO). Recently, the U.S. exportation of artificial intelligence and internet of things patents in the form of foreign sales of articles embodying U.S. patents and international technology licenses has grown substantially. However, due to the U.S. Supreme Court's Lexmark decision reconfirming an international patent exhaustion doctrine, the asian or korean importers importing such U.S. goods embodying U.S. patents do not have to worry about patent infringement liability, even when they try to resell the patented goods to the third parties. KCAB can play a substantial role in resolving such patent disputes due to qualified expert arbitrators and the International Rules of KCAB which ensure impartiality and independence of the arbitrators.

Hair styling has a significant influence on human social perception. An increasing number of people are learning hair styling and obtaining hair designer licenses. However, it takes a considerable amount of money and time to learn professional hairstyle and beauty techniques for hair styling. Since COVID-19, there has been a growing need for offline and video lectures due to the decline in onsite training opportunities. This study provides a field practice environment in which real hair beauty is performed in a virtual space. Further, the hairstyle that is most similar to the user's hair taken with a webcam or mobile phone is determined through an image matching system using the speeded up robust features (SURF) method. The matching hairstyle was created into a three-dimensional (3D) hair model. The created 3D hair model uses a head-mounted display (HMD) and a controller that enables finger tracking through mapping to reproduce the haircutting scissors' motion while providing a feeling of real hair beauty.

Gas & Oil plant construction projects are increasing recently all over oil-producing countries. An EPC (Engineering, Procurement and Construction) company, which participates in the plant projects, should possess pertinent engineering licenses and EPC management skills to create high added-value. Nonetheless, there exist various risks involved in the EPC life cycle process due to such characteristics of construction projects as long duration of construction time and complicated processes along with the procured goods or services subjected to various logistics. The objective of this paper is to analyze the overall EPC life cycle for proper process and to examine various information and document. Additionally, the principal data for the analysis of the EPC process are derived from personal interviews with experts and specialty contractors of the plant projects. The results of this study would be widely used as a guide for efficient and effective management of overseas gas plant projects.
