This paper presents the effects and the regional power distribution of an increase or a decrease of a power reserve by load flow calculations under seasonal load patterns of each country for the future power shortages faced by the metropolitan areas or by the southeastern area of the South Korea in North-East Asia. In these connections, the types of a power transmission for interconnection consist of the 765kV HVAC and the HVDC. In this paper, the various cases of the power system interconnections in Far-East Asia are presented, and the resulting interconnected power systems are simulated by means of a power flow analysis performed with the PSS/E 28 version tool. The power flow map is drawn from data simulated and the comparative study is done. In this future, a power flow analysis will be considered to reflect the effects of seasonal power exchanges And the plan of assumed scenarios will be considered with maximum or minimum power exchanges during summer or winter in North-East Asia countries.

A case of bronchogenic cyst of the posterior mediastinum in a boy of 5 years of age was encountered at Seoul University Hospital. Scarcity of case reports in Korea and Japan suggests that bronchogenic cyst is a relatively rare entity in the Far East.

Distribution, population structure, and growth of the bivalve Protothaca euglypta were investigated for clams collected from the northwestern part of the East Sea of Russia. This species is distributed in further northern area than it was found earlier. In the southern area, this clam is found in the intertidal zone, up to 8 m in depth. It is one of the most numerous infaunal species of bivalves, and protected to wave action in the gravel-pebble and sand with rubble biotope. Population density of P. euglypta reaches 500 $spc./m^2$, and biomass 2 $kg/m^2$. Size and age composition of the local settlements and allometric growth of P. euglypta depend on a biotope. The growth rate of P. euglypta considerably reduces in case of the northern boundary area, whereas life span increases.

As the lifestyle of people today is evolving, the desire for convenient but nutritious food to replace home-cooked meals is increasing. As the market for Home Meal Replacement (HMR) has already reached 17 hundred billion Won, many studies on HMR selection attributes have been conducted, using traditional Importance-Performance Analysis (IPA). However, it was found that traditional IPA had some limitations. Therefore, the study used both traditional and the Revised IPA to examine the selection attributes of HMR sold at large discount store to compare outcomes. The results of the study show that by using the Revised IPA, many attributes differed from those found by the traditional IPA. Consequently, the study revealed aspects that have both linear and nonlinear relationships with customer satisfaction. Implications of this study could provide the foundation of business strategies for HMR manufacturers.

The present world economic powers are divided into three major economic blocks such as EU, NAFTA and North - east Asian Region. In N-E Asian Region, Beijing. Seoul, Tokyo and Shanghai are already bridged economically forming transaction belt with the population of seven hundred million people around the belt. The countries as China, Mongol far - east Russia are rich in natural resources. on the other hand Korea and Japan are superior in technological know-how than that of communist and socialist countries. If we try to be eager to join together with the resource rich countries to the countries of technological know - how as Korea and Japan. The North - east Asian region will be jumping up to the most prosperous and super economic power in the coming years in 2040-2050.

The bivalve molluscan fauna of Ulsan Bay, East Sea coast of Korea, is summarized, based on original and literature data. The fauna consists of 61 species belonging to 20 families. Seven species are identified only to genus level. Two species (Carditellopsis toneana (Yokoyama, 1922), Carditidae and Fulvia hungerfordi (G.B. Sowerby III, 1901), Cardiidae) are new records for the East Sea coast of Korea, and one species (Crenella decussata (Montagu, 1808), Mytilidae) is a new record for Korea. Biogeographically, Ulsan Bay's bivalve fauna is subtropical with a predominance of tropical-subtropical species, 21 species, or 39% of the total species number, subtropical, 14 species, or 26%, and subtropical-boreal (mostly subtropical-lowboreal), 11 species, 21%, totalling 86%. A remarkable feature of the Ulsan Bay fauna is the presence of tropical-subtropical species not found in Yeongil Bay but common in tidal flats and shallow waters of the Yellow Sea and the southern part of Korea. A cold water mass appearing off the southeast coast of Korea near Ulsan in summer seems responsible for the presence of boreal-arctic species in this area.

In 2000, the economy of Asia made a V-character type recovery from the currency and financial crisis in 1997. The increase in exports is assumed to be one of the causes. To negotiate with foreign countries, English must be indispensable in many cases. In this study, we investigated how English education is performed in East Asian countries while focusing on English textbooks. We metrically analyzed some textbooks used junior high schools and high school in Japan and Korea, and elementary schools in China and Singapore to compare them with U.S.A and U.K textbook. We investigated some characteristics of character-and word-appearance of English textbook using an exponential function. Moreover we derived the degree of difficulty far each material through the variety of words and their frequency on the basis of the required English vocabulary in Japanese junior high schools. As a result we could show at which level of U.S.A. or U.K the English textbooks used in East Asian countries are.
