This study aimed at identifying the characteristics of current Earth Science Curricula in several countries in terms of their format, objectives and contents and discussing about them. The curricula(including textbooks) were collected from 6 countries The United States of America, England, Australia, Japan and The Republic of China. Here are the results of this study ; 1. Earth Science should be teached in high school and assigned at least 8-10 unit. 2. In Earth Science objectives, scientific inquiry methods through observation and experiment and mutual relationship among science, technology and society must be stressed. 3. The contents of Earth Science must did with experimental and activity rather than understanding in order to induce students to how more intersts in Earth Science. 4. There is a growing tendency for Earth Science Education to be attached importance to life environment and career education.

Many plants collected at Japan, China, Korea, Imdonesia and South America were applied to antitumor and / or cytotoxic screening tests against Sarcoma 180 ascites in mice and / or V-79, KB, P388 cultured cells. On the course of these screening tests, alcoholic extracts of Forsythia viridissima (Oleaceae), Eurycoma longifolia(Simaroubaceae), Rubia cordifolia and R. akane(Rubiaceae), Cissampelos pareira and Abuta concolor (Menispermaceae), Nardostachys chinensis (Valerianacese), Mansoa alliaceae (Bignoniaceae), Casearia sylvestris (Flacourtiacear), Maytenus ilicifolia (Celastraceae), Hedychium coronarium (Zingiberaceae), Croton palanostigma(Euphorbiaceae), Cocculus trilobus(Menispermaceae), Ginkgo biloba(Ginkgoaceae), Alpinia galanga and Cucculus zanthorrhiza(Zingiberaceae), Evodia rutaecarpa(Rutaceae), and Periploca sepium(Asclepiadaceae) showed significant activity and their active principles were clarified. In this paper, a few antitumor substances in above plants are introduced.

Retro, one of these fusion styles, was found in various pattern in fashion. Recent fashion trend shows coexistence with variety which cannot be represent by one or two themes, and introduces various images in a season. Therefore, this study was found three fusion image of Retro pattern which has appeared since 1990; Romantic, Ethnic, and Hippie-look. shown in VOGUE, BAZZAR and etc. 1, Romantic image overcame the exaggerated style of 18th century and expressed in a volume gown, a tight dress of high-waist, and bustier. In addition, beads or sequin became more brilliant and gorgeous which decorated the whole clothing. 2. Ethnic image was expressed with fusion of particular traits from all of the world such as Japan, China, India, South America, Greece, and Africa. 3. Hippie-look image has been shown in slim & long silhouette style, and fusion styles of romantic factors or ethnic factors were also found. Retro as one of the phenomenon of fusion was found in romantic image, ethnic image and hippie-look Image.

The medical-device market of Myanmar in the recent Asian region is where the influences of Thailand, China, India and Singapore are being shown considerably with the lift-up of economic sanctions by America and the West. However, although the global capital and liberalization have widened the openness and the international concerns, the relative Myanmar's medical environment demands an active assistance and improvement. The study, recognizing the importance of Medical-Devices and their market conditions emerging as key business for knowledge-based industry, aims to obtain consequential meaningful suggestions, pursuant to relative export-concentration and sustainable market growth of Medical Devices, by analyzing inter-nation trade intensity for key Medical Device items. To do so, this study selected 8 nations in total by reviewing three points: core Medicine-advanced countries, geographically adjacent countries to Myanmar, and relative export-concentration.

The rapid development of computer technology and widely application of artificial intelligent provide technology support for realizing navigation automation on the sea. which has achieved great success in shipping advanced countries like japan, England, America, Germany and also in the developing country, China. However, it still remains in the studying Period up to now in aspects of collision avoidance decision-making mathematical model and reasoning mechanism. In this paper, approaches are proposed to establish the collision avoidance automation system. One of them is based on the former studies to realize automation system by make use of finite state machine theory and following the International regulations for Preventing Collision at Sea, 1972. The others are to establish the new idea about automatic collision avoidance system by taking advantage of the free flight idea, hybrid system, game theory used in air traffic management studies in recent years and the common characteristics in both air and sea traffic management.

In this study, we provide trends on alternative fuel vehicles promoted by postal agencies in 10 countries in North America, the EU, and Asia. It describes the specifications of most EV vehicles in operation, plans, and strategies to replace existing internal combustion engines with new vehicles in the future and provides the current status of alternative vehicle charging networks in each postal agency. This paper will help postal agencies, logistics companies, automobile companies, motorcycle companies, and even individuals who want to use vehicles with alternative fuels, such as electric vehicles, on strategies to establish and implement before introducing and operating the vehicles.

Subsocial woodroaches of Cryptocercus occur in high mountainous forests in temperate regions and they live in a family in complicated galleries of rotten logs. A prominent feature of the geographical distribution of Cryptocercus is the wide disjunction between the eastern and western species in North America, and between West China and Northeast Asia. Recently, five species of the genus were added from Asian areas and two of them are distributed in Northeast Asian areas. We examined morpho-anatomical structures of male genitalia in Manchurian and Korean Cryptocercus, focusing on male genital hooks and subgenital plates.

An aquatic oligochaete species, $Ripistes$ $parasita$ (Schmidt, 1847) collected from Ganghwado Island in Korea, is described and illustrated. Specimens inhabiting on aquatic vegetation at the edge of the streams were collected with a plankton hand net. Morphological features of present specimens such as the number of long hair chaetae per bundle and their length in VI-VIII, and shape and size of ventral chaetae are concordant with those of previous reports on this species. The genus $Ripistes$ contains one species, $R.$ $parasite$ which is distributed over, Europe, North America and eastern part of Asia including China and Japan. This is the first record of $R.$ $parasita$ in Korea.

This research empirically examined changes in the images of Korea over three points in time among Japanese, Chinese, and U.S. visitors to South Korea. Between March 14 and May 31, 2005, about two to three months after the 2005 Seoul International Sports & Leisure Industry Show ended, 153 tourists from America, 129 from China, and 156 from the Japan completed the survey instrument. The results from a General Linear Model (GLM) with repeated measures showed that tourists from all three countries had more positive images after the Seoul International Sports & Leisure Industry Show than before it. It was concluded that the 2005 Seoul International Sports & Leisure Industry Show appeared to have a significant positive effect in enhancing the image of South Korea. The study suggests that an internationally significant trade Show can change the image of a tourism destination in a short time period.

A panic device is a type of door lock that opens when pressed or pushed by the body, so it is an emergency escape device designed to easily open the door and escape in an emergency situation such as fire or earthquake. It is an ideal door handle for an emergency exit. Because many people move quickly and it is easy to use, it is common in Europe and North America, but in Korea, the product is expensive, so it is used on a limited basis in luxury buildings such as hotels, but its use is gradually increasing. East Asian countries such as Korea, China, and Japan mainly prefer the North American type. The design of the penic device used in is a uniform and universal design, and research and development of a new design of the penic device was required to develop a new design type product considering the aesthetics of the building.
