Field orientation of rotating field machines is influenced by various machine parameters. Most unpleasant are those parameters which vary during machine operation, such as the stator and rotor resistances. Permanent influences of resistance variation in steady state operation could have serious consequences. Also transitory influences are often disturbing. In this paper a control method for a current-fed synchronous machine is presented in which both permanent and transitory parameter influences are suppressed as much as possible.

본 연구는 최근 기하 교육 동향과 전미수학교사협의회에서 2000년대의 수학교육의 방향과 관련해서 제시한 기하 교육의 규준에 비추어 현실적 수학교육에 기초한 네덜란드의 초등학교 기하 교육과정에 대해 알아보고, 우리나라의 초등학교 도형 영역 지도를 위한 시사점을 제시하는 데 그 목적이 있다. 이런 목적을 달성하기 위해 네덜란드의 초등학교 기하 교육의 역사를 살펴보고, 네덜란드의 초등학교 기하 교육과정에 중요한 영향을 미치는 요소인 일반 목표와 기하 영역의 핵심 목표, RME에 기초한 네덜란드의 초등학교 수학 교과서의 지도 내용과 지도 방법의 특징을 살펴보았다. 그 결과 우리나라 도형 영역의 교육과정과 교과서 개발을 위해 논의할 문제로 지도 내용의 측면에서 공간 방향의 도입, 공간 시각화와 공간 추론의 강화, 지도방법의 측면에서 공간적 접근과 도형적 접근의 균형, 직관적 접근의 중시, 통합적 접근의 고려 등을 제안하였다.

The paper describes the validation of two time domain methods to simulate the behaviour of a destroyer operating in steep, stern-quartering seas. The significance of deck-edge immersion and water on deck on the capsize risk is shown as well as the necessity to account for the wave disturbances caused by the ship. A method is described to reconstruct experimental wave trains and finally two deterministic validation cases are shown.

The object of this research is to take a bilateral look into cultural exchanges of the Netherlands and Japan through the East India Company and thereby improve the general understanding in regards to the exchanges of costume cultures between the East and the West. The study conducted qualitative analyses on features of contemporary costumes of the Netherlands and Japan from 1602 to 1799 by investigating the secondary sources, such as the histories of costumes, arts, and literature. The results are as follows; the traditional sleeves of the Japanese Kimono were basically cut out in a straight line. However due to the growing popularity of the kimono home gown in Europe, the producers of the kimono in India as well as several other European countries modified them into western-style sleeves. Regarding the costumes of the Netherlands, which were introduced to Japan, the study found that Japan imported Dutch fabrics, instead of specific clothing items. In Japan, costume controls and anti-conspicuous consumption regulations among social classes including a closed-door policy had negative effects on both developments and exchanges of costumes of the country. However, when it comes to the Jinbaori, a costume for ruling classes, Japan was open to using fabrics, patterns and designs of the West. In light of what have been discussed so far, the study confirmed that the costume exchanges between the two countries started long after their first business of the general cultural exchanges. Though it is clear that the advancements in the natural sciences that the Japanese made can be attributed to the West, Japan was one of the nations that impacted the costume cultures in Europe.

The Netherlands is a human-made country and an extremely well-designed European country as well. The general Dutch spatial planning for the city and environment takes place at a regional level. The local community determines the primary development conditions, and the prospect is included in a legally binding land-use plan. Especially, Rotterdam is a representative port city as the center of world trade and the gateway to western Europe. According to the history of war, the city reconstruction and the movement of the port area have led to a general change in Rotterdam and the regional redevelopment project on the southern port area of Mass river for the expansion of city functions and the balanced development. The research purpose is to understand the spatial development of the Netherlands city-region based on the analysis regarding the Kop van Zuid project, which is a representative implemented case in Rotterdam. The theoretical framework is the five dimensions and twelve indicators of territorial governance from the TANGO research project by the EU. The target case is assessed by planning and social aspect, respectively, and the results are discussed based on the theoretical framework. This research has the possibility to be utilized as advanced research by the European perspective for spatial development in other city-regions with the port area, such as Incheon and Busan in Korea.

Since 1960's Korea has undergone rapid modernization which has problem on the change of industrial society. This phenomena led the trend that tended to produce residence only in the quantity. However, supply-oriented policies for increasing the penetration rate of housing but only in the mass production of housing, the quality of life has not reached the demand of the residents. In this reason, the purpose of this study is to derive the factors of social integration plan through the public rental housing with characteristics of social housing. Therefore, the subjects of this study are social integration public rental housing in USA, Netherlands and Korea. Specially USA and Netherlands are advanced countries where public rental housing policies and design have been established long ago. In this reason, it is needed to analysis the cases and find a new method to compare with Korea's public rental housing. Accordingly it is expected that the result of case studies shows First, it is necessary to realize a community plan that continuously encourages communication and participation for social integration. Second, It should aim at a mixed community of small-income groups through private-public cooperation rather than government-led large scale public housing construction. Third, it is needed that develop various policies and systems and realize them in social integration plan.

The number of species of non-native and invasive marine algae is growing, with concomitant public concern about native ecosystems and coastlines. Gelidium vagum, recently introduced from northeast Asia to Europe and North America, commonly occurs from the intertidal to subtidal zones in Korea, China, and Japan. To investigate the level of genetic diversity of native populations, we analyzed mitochondrial cox1 and cob from 108 specimens of G. vagum from Korea, China, eastern Russia, including from the Netherlands and USA. The haplotype network of individual and cox1 + cob datasets revealed no genetic structure in local populations, suggesting genetic flow between Korean populations. Our results corroborate a typical pattern of genetic diversity for introduced species, with low levels in introduced populations and high levels in native populations. All haplotypes were shared between the Netherlands and USA, but not between Korea and the Netherlands / USA except cox1. Additional sampling will identify donor populations in native northeast Asian waters. This is the first report of the utility of the mitochondrial coding cob sequences in red algae.
