Every finite solvable group is only a subgroup of an M-groups and all M-groups are solvable. Supersolvable group is an M-groups and also subgroups of solvable or supersolvable groups are solvable or supersolvable. But a subgroup of an M-groups need not be an M-groups . It has been studied that whether a normal subgroup or Hall subgroup of an M-groups is an M-groups or not. In this note, we investigate some historical research background on the M-groups and also we give some conditions that a normal subgroup of an M-groups is an M-groups and show that a solvable group is an M-group.

A revolution in weather and climate forecasting is in progress. This has been made possible as a result of theoretical advances in our understanding of the predictability of weather and climate, and by the extraordinary developments in supercomputer technology. New problem areas have been discovered and different solutions have been found by the recent high performance computers whose performance has been increased rapidly. Such advances in the computational performance may change the strategy of development of numerical models and prediction methods. This paper discusses a brief history and current status of the supercomputers in institutions for research and forecast of weather/climate. The main purpose of this study is to provide the preliminary information about supercomputers such as architecture of system and processor. Such information would be useful for meteorologists to understand the features and the preference of supercomputers in each institution.

Traditional medical knowledge and its biological resources, including Korean Medicine, has regarded as an important object of intellectual property rights. International organizations have been discussed and implemented various treaties on how to exercise and protect the property rights of traditional medicines. In Korea, the governmental policies and the academic societies have endeavored to establish the protection method and academic foundations of Korean Medicine's intellectual properties. This study will examine the current situation of discussions in major international organizations and Korean governmental policies related to the protection of traditional medical intellectual properties. Furthermore, this paper will contemplate the possible arguments and countermeasures to protect the traditional knowledge of Korean Medicine. We hope that this study will contribute to find the reasonable and effective ways of protection of Korean Medicine's intellectual property rights.

This paper attempts to reveal little-known pages from the history of relations between the peoples of Central Asia and Korea based on materials derived from written sources and modern scientific literature, as well as from medieval wall paintings from the early medieval Afrasiab Palace of Varhuman, the ruler of Samarkand, and from stone sculptures of Sogdian figures contained in Silla royal tombs. Korea's interest in the western lands led to its contact with Buddhism, which spread and later flourished in all three Korean kingdoms (Koguryo, Paekche and Silla). The spread of Buddhism in turn motivated a number of Korean monks to undertake pilgrimages to India via Central Asia. Hyecho, a young Silla pilgrim, left evidence of his journey via the South China Sea to India in 723 AD. Paul Pelliot discovered a report from Hyecho's journey entitled Notes on Pilgrimage to Five Regions in India (Wang Wu Tianzhuguo zhuan) in the Dunhuang caves in 1908. Hyecho's contributions are worthy of attention, substantially complementing knowledge available for this little-studied period in the history of South and Central Asia. The information contained in Hyecho's manuscript is, in fact, considered the most significant work of the first half of the 8th century. Research regarding the relationship between Central Asia and Korea remains underdeveloped. Existing historical evidence, however, including the above mentioned Samarkand wall paintings, depicts the visits of two Korean ambassadors to Samarkand, and evidence from Silla tombs suggests the presence of diplomatic relations in addition to trade between the two regions. Overall, the history of the relationship between Central Asia and Korea yields new insights into how and why these distant countries sustained trade and diplomatic and cultural exchange during this early period. Taking into account Korea's growing interest in Uzbekistan, especially in its history and culture, this article can act as a catalyst for studying the history of the two country's relations.

Mathematics and arts are reflection of the spirit of the ages, since they have human inner parallel vision. Therefore, in ancient Greek ages, the artists' cannon was actually geometric ratio, golden section. However, in middle ages, the Euclidean Geometry was disappeared according to the Monastic Mathematics, then the art was divided two categories, one was holy Christian arts and the other was secular arts. In this research, we take notice of Renaissance Painting and Perspective Geometry, since Perspective Geometry was influenced by Renaissance notorious painter, Massccio, Leonardo and Raphael, etc. They drew and painted works by mathematical principles, at last, reformed the paradigm of arts. If we can say Euclidean Geometry is tactile geometry, the Perspective Geometry can be called by visual geometry.

This survey paper aims to compare two significant figures in the history of Haute Couture e.g, Paul Poiret and Coco Chanel, who played a leading role between 1910 and 1930. It is found here that they have common features with respect to giving freedom to body through costume, enlarging Garconne Mode, creating more value of Costume Jewelry, exploiting advertisement strategy using models, proving exotic styles, and last but not the least contributing to Haute Couture. The research shows, however, that Poiret differs from Chanel in that he made most of various natural colors whereas Chanel used black or beige colors that had been rarely used woman wear previously. They also differed in using fabric, permitting copy by others, ingredients and bottling of perfume, meaning of silhouette. This kind of comparative research is expected to provide more understanding of fashion history and to contribute to more rigorous analysis of key success factors of designers in his or her age of fashion.
