Superconducting motor has a lot of benefits from high power density for ship propulsions, so a number of research project are in progress worldwide. Despite of all the benefits, there is always a difficulty of cryo-moving part for conventional air-core superconducting synchronous motors. In order to get rid of this moving cryogenic part, we propose a homopolar superconducting synchronous motor, which has high temperature superconducting armature and field coils. The rotor is supposed to be made of iron only and excited by the stationary HTS field coils. The stationary field coils make the cooling system simple and easy to realize because there is no cryo-moving part. A design result of a 10 hp homopolar synchronous motor is presented in this paper. The self and mutual inductance of the motor having the size of air gap as variable parameter are calculated by a 3-dimemsional finite element method. The value of design variables such as the dimension of a motor and the number of turns, etc. is decided by performing the coordinate transformation of the calculated inductance. The operating frequency is supposed to be below 5 Hz for low rotating speed which is needed for a purpose of ship propulsion. Low frequency also has the benefit of low AC losses.

Time poverty is a kind of objective and subjective state which a person does not have a enough time to do his/her work or is in the mood to do something in a hurry. The major of family resources management has studied time as a resource to manage for long years. How to manage time has been a major part in education of family resources management. The education itself in nature has focused to inform knowledge and the disciplines of time management, to the students, on the other way, has a rare interest with a each student how to apply them or whether do in practical. Coaching is characterized as a practical learning and mutual communication skills with open questions, which help for a individual student to find his/her own goal related with time poverty or furthermore, whatever he/she wants to achieve in life. If the benefits of the education of family resources management as well as the benefits of practical learning of coaching could be merged in education on time management, the effectiveness of education to resolve time poverty is able to be increased. For the purpose, this study suggests a coaching approach in education of family resources management to resolve time poverty, by some comparisons of family resources management and coaching about time and time management.

On July 6, 2021, the Ministry of Education revised and announced the operating regulations of the undergraduate co-op with the aim of protecting students rights and student-centered operation based on mutual benefits for students and institutions. Therefore, the purpose of this study is to analyze universities' perceptions against the amendment of regulation of the Ministry of Education's into universities/college, regions. According to a survey of 75 KACE, we found that colleges are more difficult than universities in terms of administrative work, company participation, reduced opportunities for co-op, and managing participating companies. Next, most of the regional differences in difficulties were not significant, and only the decline in company participation rate was more difficult in Daegyoung/Gangwon/Chungcheong/Jeju than in the metropolitan area. Finally, policy directions such as the differential application of practical support expenses according to the size of the company, tax benefits for institutions, and clarification of the concept of job training were presented.

본 연구는 고객이 화장품을 구매할 때 지각하는 구매체험의 요인들을 Schmitt(1999)가 주창한 전략적 체험 모듈(SEM)을 이용하여 다섯 개 요인(감각, 감성, 인지, 행동, 관계)으로 분류하고, 이들 요인과 고객의 화장품 추구혜택, 소비자와 브랜드간의 관계형성에 관한 일련의 관계를 조명하여 화장품 기업에 전략적 시사점을 제시해보고자 하였다. 연구결과를 살펴보면, 화장품 추구혜택 중 기능성은 구매체험에 모두 유의한 영향을 미치는 것으로 나타났으며, 브랜드는 감각과 인지-행동-관계에 유의한 영향을 미치며, 감성에는 유행성만이 유의한 영향을 미치는 것으로 나타났다. 또한 소비자의 화장품 구매체험 중 인지-행동-관계가 소비자-브랜드 관계에 모두 유의한 영향을 미치는 것으로 나타났으며, 사랑과 열정에는 감각이 유의한 영향을 미치고, 상호몰입과 친밀감에는 감성이 유의한 영향을 미치는 것으로 나타났다. 남녀 간에는 화장품 추구혜택 요인 중 유행성, 경제성, 기능성에서 유의한 차이를 나타냈으며, 유행성과 기능성은 여자가 남자에 비해 높게 나타났고, 경제성은 남자가 여자보다 좀 더 높게 나타났다. 또한 화장품 구매체험 요인 중 감성과 인지-행동-관계에 유의한 차이를 보이고 있으며, 여자들이 남자들에 비해 높게 나타났다. 마지막으로 화장품 추구혜택 중 기능성은 여자, 남자 모두 감각, 감성, 인지-행동-관계에 유의한 영향을 미치는 것으로 나타났으며, 여자는 브랜드가 감각에 유의한 영향을 미치는 반면, 남자는 브랜드가 인지-행동-관계에 유의한 영향을 미치는 것으로 나타났다. 결론적으로, 화장품기업들은 다양한 국내외 브랜드들이 치열한 경쟁을 하고 있기 때문에 차별화된 경쟁우위를 갖기 위해서는 소비자의 피부에 적합하며 기능적인 화장품을 제공해야 하며, 소비자들이 이를 다양한 구매체험을 통해 구매할 수 있도록 하여 브랜드와의 강한 관계구축에 힘써야 할 것이다.

This paper focuses on the development prospects of the UK after Europe, the development situation of the EU and the world's democratic issues were discussed. Professor Zhou Yushu that the old EU pattern may no longer be suitable for contemporary development trends, the need for reform and create a new pattern of mutual benefit and win-win situation. Professor Thomas believes that the impact of Britain's departure from Europe should be viewed from a dialectical perspective, and the benefits and disadvantages of China's economic development plan will be positive for the economic development of Europe as a whole. With the common development of China.

South and North Koreas are putting forth efforts to overcome the distrust and animosity of the past 50 years to open an era of harmony and cooperation where the two halves can work together for mutual benefits. As part of those efforts, both parties are working now to reconnect the railways between the North and the South that remained broken for the past 60 years. The South and North have had different railway systems for more than 50 years. To solve these complicated issues, appropriate investigation and analysis of North Korea railway system should be proceeded. It is necessary to study the railway system and integration methodology for effective operation of the two korea's railway systems. Therefore, in this study, effective unification scheme of South and North Korea railway system is proposed based on appropriate investigation about operation of inter-Korea railway system.

File sharing through P2P was decided as illegal according to Supreme Court of the U.S. and the Highest Court of Korea in 2005. Metro-Goldwyn-Mayer Studios Inc. et al. v. Grokster, LTD., et al. and Soribada v. Korea Association for Music Providers have the same ground for decision. P2P service company has vicarious liability for illegal file sharing of its customers. Balance between copyright protection and development of technology was considered in that decision. Programmer who will develop new program for free download and copyright holders who will exploit every measures to protect their right may compromise for their mutual benefits.

Korea and Japan have maintained an intimate relationship of economic exchange. However, even though both countries have made sound advances in the ASIAN market, they have not established mutually remarkable cooperative relations and advances in the ASIAN market. If korean companies with abundant experience and management ability provide able managers and skilled labor and if Japanese companies provide construction technology, capital and information, they could enjoy enomorous mutual benefits by advancing in the area of plant construction in foreign countries. Therefore, if they cooperate with each other by establishing complementary cooperation, both countries can gain an advantage in international competitiveness with western advanced countries.

Wireless charging is a technology of transmitting power through an air gap to an electrical load for the purpose of energy dissemination. Compared to traditional charging with code, wireless power charging has many benefits of avoiding the hassle from connecting cables, rendering the design and fabrication of much smaller devices without the attachment of batteries, providing flexibility for devices, and enhancing energy efficiency, etc. A transmitting coil and a receiving coil for inductive coupling or magnetic resonant coupling methods are available for the near field techniques, but are not for the far field one. In this paper, the wireless power transfer (WPT) circuit by using magnetic resonant coupling method with a resonant frequency of 13.45 Mhz for the low power system is implemented to measure the power transmission efficiency in terms of mutual distance and omnidirectional angles of receiver.
