The Pacific Island Forum that consists of 14 island countries in the South Pacific has long been the focus of keen attention from East Asian countries such as South Korea, Japan and China. The South Pacific area was controlled by Japan right after the First World War. The League of Nations bestowed the right of trusteeship over the region to Japan, one of the victors in the war. However, the U.S. considered the area indispensible for its security interests in the Pacific after victory in the Second World War. With the end of Cold War period, the region again began to gain the competitive attention of Japan, China and Korea. Japan has made efforts to give economic assistance to this region by holding the Japan-Pacific Islands summit every three years. In addition, Japan is promoting a security engagement with this region by dispatching Self Defense Forces with the aim of initiating construction and development projects. In response to Japan's active involvement in the region, China also began to convene a summit meeting with these countries in 2006, making pledges of economic assistance. Furthermore, Chinese civilian companies struck deals of investment with municipal institutions in the region with a view to enhancing China's influence in the region. Japan's and China's active engagement in the region has galvanized South Korea to craft a more effective strategic approach to the region.

When a multinucleate cell of Bryopsis plumosa was collapsed by a physical wounding, the extruded protoplasm aggregated into numerous protoplasmic masses in sea water. A polysaccharide envelope which initially covered the protoplasmic mass was peeled off when a cell membrane developed on the surface of protoplast in 12 h after the wounding. Transmission electron microscopy showed that the protoplasmic mass began to form a continuous cell membrane at 6 h after the wounding. The newly generated cell membrane repeated collapse and rebuilding process several times until cell wall developed on the surface. Golgi bodies with numerous vesicles accumulated at the peripheral region of the rebuilding cell at 24 h after the wounding when the cell wall began to develop. Several layers of cell wall with distinctive electron density developed within 48-72 h after the wounding. Proteome profile changed dramatically at each stage of cell rebuilding process. Most proteins, which were up-regulated during the early stage of cell rebuilding disappeared or reduced significantly by 24-48 h. About 70-80% of protein spots detected at 48 h after the wounding were newly appeared ones. The expression pattern of 29 representative proteins was analyzed and the internal amino acid sequences were obtained using mass spectrometry. Our results showed that a massive shift of gene expression occurs during the cell-rebuilding process of B. plumosa.

A study was designed to assess the current status of weaning practice and to serve as a guideline of a processed baby foods through the an in-depth survey focused on the Seoul and Kyunggi area. 16.I% mothers surveyed were breast-fed and 54.6% were formula-fed. They mostly wanted to obtain information about processed bady foods and the adequate amount and weaning method of bady foods and showed deep interest in recipe of weaning foods. The average score of weaning knowledge which is counted by mothers'responses was IS.S and was significantly high in the high-educated group. The average Period when those surveved began weaning was $4.3\pm1.8$months and hight-educated mothers began weaning earlier than low-educated group. 77.O% mothers prepared weaning foods at home. The most popular recipe were gruel with meats and vegetables(52.6%) and they usually used mashed or grinded fruits(69.7%). 36.6% of the mothers surveyed used processed baby foods on sale once a day on the ground that such a small package is very convinient to carry. The processed baby foods which the mothers wanted to develope was the already-cooked type and to be able store at room temperature.

This study analyzes Chinese dresses featured in propaganda posters since the mid-$20^{th}$ century as well as explores the political characteristics of dress. This study used an in-depth interview method to investigate information from 10 Chinese familiar with public awareness and donning practices of the Chinese from 1949 to present. Interviews and analysis provided the following conclusions. First, Zhongshan-zhuang, Liening-Zhuang and Bulaji were widely worn in the Reconstruction because of the revolutionary spirit; in addition, Huayishang also became simultaneously popular as a means to reflect the new aspects of socialism. Second, Jufu/Junbianfu were the most common dresses during the period of Cultural Revolution because the government used various mechanisms to control public opinion. Third, Western fashion began to enter the Chinese market and suit wearing by the Chinese became a symbol of the Reformation and Open-door policy. Traditional dress is no longer a symbol of Feudalism and is a part of Chinese culture that has been reaccepted in the Reformation and Open-door times. Finally, during these 60 years, Chinese dress has obvious political characteristics, but began to change. The changes of political characteristics were, de-politicization expressed by the introduction of Western ready-made, permissions for traditional dress and diversification/ individualization.

This paper studies the style emergence of Liujin Dougong in the ancient Chinese architecture. Dougong is the bracket set of the ancient Chinese wood structural architecture, and Liujin Dougong is one of the late styles of Chinese Dougong. It emerged in the period of the Ming Dynasty and has been installed in imperial palaces and imperial temples till the late period of the Qing Dynasty. Through the long term field survey and documental investigation, this research found out the some prototypes of Liujin Dougong among the earlier Xia-ang style Dougongs in the Song and Yuan Dynasty architectures. The symptom of style change appeared in the bracket composition. In the beginning, because Shuatou, the horizontal member just on Xia-ang was needed to be fixed to the inner main structure system, it was changed to the diagonal member and replaced Xia-ang. It brought continuous changes, the other horizontal members of Dougong also began to change to the diagonal form. And in accordance with these compositional changes of Dougong members, the decoration of inner parts also began to change. This paper analyzed every step of the compositional and decorative changes from Xia-ang Dougong style to Liujin Dougong style. In the addition, it also proposed the typical model of Qing style Liujin Dougong of which tail end is not placed on the beam and is just placed under the purlin, based on the its own research and analysis.

We surveyed Korean pregnant women who participated in the Maeil mothers' club and factory tour from March to April, 2004 and assessed volunteers' hemoglobin (Hb) levels. The average Hb level of 747 subjects was $11.5{\pm}1.5g/dl$ and anemic subjects were 268 women, 35.9% of total subjects. The ratio of anemic subjects was 42.9% in the first trimester, 43.6% in the second trimester and 29.1 % in the third trimester. About 87.9% of subjects began to take health foods after conception. Seventy nine percent of subjects took iron supplement as one of health foods and 73.8% of them began it in the second trimester. The results of this study showed that health foods were more effective than iron supplement alone in improving the iron status of Korean pregnant women. Therefore, the better improvement effects are expected when pregnant women begin health food-based approaches as early as possible before pregnancy to improve pre-pregnancy iron reserve.

It may be said that ancient wild Chinese garden had been founded during Qin dynasty and completed through Han, Sui and Tang dynasties. At first used as hunting areas for kings, the ancient resort forests began to take forms of garden. They dug a pond in the garden and made a simulated mountains with the soil that came from the excavations for the pond and suc pavilions has Gyong, Ru, Gak etc. were built around the pond. The ponds were different in size from those in Korea, being of the lake-like size. they made three island in the pond, which were the islands of Taoist hermits with supernatural powers, called Bong-lae, Young-ju and Band-jang respectively. the traditional of making those islands began in the Qin era and were completed in the Han era, being descended to posterity as a traditional garden structure of 'three islands in one pond' garden style. Such style was brought to Korea and first appeared as Kung-Nam-Ji in Back-jae kingdom and then brought to Japan, becoming the tradition of constructing ponds from early Heian era. Those lake-like huge Chinese ponds constituted the core of ancient garden where various feasts took place. Such ponds were also placed at the center of the gardens and played the roles of feasting garden ponds. Through the above-mentioned studies of the ancient Chines garden, the origin of them and the influence of the ancient Chinese ponded garden upon those of Korea and Japan were investigated.

This study examined the casting analysis of fuel pressure regulator of LPI vehicles. We aims to predict all the phenomenon accompanied by flow and solidification in die casting, and maximize productivity and quality through optimal casting design. As a result of comparing Types A and B of casting design, it was found that the number of overflow affected flow, flowspeed and solidification temperature. And there was a minute difference between solidification temperatures at thick section of the spare parts. Solidification began at temperatures of $624^{\circ}C{\sim}630^{\circ}C$ but after the casting was completed, temperatures at the center of the parts were $600^{\circ}C{\sim}614^{\circ}C$ Temperature of molten metal showed optimal flow at temperature of $680^{\circ}C$. It began to solidity around at $650^{\circ}C$ and to be cooled between $580^{\circ}C{\sim}550^{\circ}C$ in high speed. When the process was analysed through a computer simulation, it was found that hardness of regulators manufactured through Type B of overflow was above $H_R60$.

Maturation and spawning of the Blackthroat seaperch, Doderleinia berycoides were investigated based on the samples captured in Korean waters from January 2008 to December 2009. Gonadosomatic index began to increase in June, and reached maximum between July to September. After spawning it began to decrease from October. Reproductive season was estimated to July-September, with peak in August. Fecundity was proportional to the size of the female, with the clutch size varying from 115,500 eggs in the smallest female (TL〓28.2cm) to 652,000 eggs in the largest (TL〓33.5cm). Size at 50% sexual maturity ($TL_{50}$), determined from mature females, was 29.6cm. Annual reproductive cycles of this species could be divided into six successive stages; immature stage (October-May), nucleolus stage (June-July), yolk vesicle stage (July-August), vitellogenic stage (June-September), ripe and spent stage (August-October).

In the medieval age of Europe when the noble people of various regions enjoyed unique cultures and life styles where made by coachbuilders. Such coaches would later affect the styles of the earlier automobiles equipped with the driving engine. Later, as the gasolines engines began to be distributed, the automobiles could afford to be flexible in terms of size and weight, while their performances and designs began to be enhanced rapidly. The important aspect of earlier automobile manufacturing was the phased development of styling which represented the pure approach to functions as well as the historical background. It can be known that such a development of automobile styling reflected the concerned industrial advancement and social influences of each region. At this juncture of time when the massmotorized modern society's demands for automobiles are unlimited and diversified, this study was aimed at reviewing the fundamental implications of automobile designs over time.
