This paper is a study on the design of the gilt-bronze sarira caskets discovered in 1959 and 1996, from a east and a west three-story stone pagodas in Gameunsa Temple site which was built in 682. One of the most interesting discoveries is the ceiling with Bokdu(覆斗) design which can be seen in Dun-Huang grotto of China, reflected upon the ceiling structure of the cover (outer casket) and the square box (inner casket). The structure of these sarira caskets, as art crafts, directly represents architectural structure of Dun-Huang grotto that was made during the early T'ang period of China. Moreover, the sarira caskets are decorated with ornate designs and these designs also can be seen on the murals of Dun-Huang grotto. Accordingly, those sarira caskets tell us creative ability and international taste of Silla's craftsmen. By tracing the origin of structure and design pattern of the sarira caskets to Central Asian and Chinese architectures, it is able to understand international style of the sarira caskets of Gameunsa Temple site.

This study aims to investigate various cultural activities of the Korean youth including the subcultural and popular cultural activities and their characteristics and influences on the youth fashion during the period 1996-2004. This study employs a qualitative approach based on the previous discussions of relevant literatures dealing with Korean youth culture and their fashion styles. The result of the study shows that the most prominent characteristic in youth fashion of the period was 'bricolage.' The appearance of 'Seotaiji' and the activities of his group laid the cornerstone of youth culture in the early 1990's. The influence of postmodernism changed the conventional sexism and androgynous outfit thrived. The androgynous effect also had strong influence on men's fashion in what turned out to be Metro-Sexual in early 2004. During the period 2000-2004 the postmodernism regained its popularity both in culture and fashion. 'Body' was also an important part of youth culture and has become the most popular and prevalent word of this era. At the same time the 'Well-Being' and sports look were the new trend of youth fashion. Sports look, also known as Caports, is one of these new trends and the most important youth fashion style like mix & match reformation. The youth became more and more aware of the body image and were interested in fashion as well. This trend awareness of their body and Well-Being image as well as their inclination to the fashion in the youth is expected to continue. Therefore the fashion industry, as their marketing strategy, needs to analyze the characteristics of the cultural trends among the youth and to prepare for the future need of youth fashion.

Objectives: Economic growth and development of medical technology help to improve the average life expectancy, but the western diet and rapid conversions to poor lifestyles lead an increasing risk of major chronic diseases. Coronary heart disease mortality in Korea has been on the increase, while showing a steady decline in the other industrialized countries. An age-period-cohort analysis can help understand the trends in mortality and predict the near future. Methods: We analyzed the time trends of ischemic heart disease mortality, which is on the increase, from 1985 to 2009 using an age-period-cohort model to characterize the effects of ischemic heart disease on changes in the mortality rate over time. Results: All three effects on total ischemic heart disease mortality were statistically significant. Regarding the period effect, the mortality rate was decreased slightly in 2000 to 2004, after it had continuously increased since the late 1980s that trend was similar in both sexes. The expected age effect was noticeable, starting from the mid-60's. In addition, the age effect in women was more remarkable than that in men. Women born from the early 1900s to 1925 observed an increase in ischemic heart mortality. That cohort effect showed significance only in women. Conclusions: The future cohort effect might have a lasting impact on the risk of ischemic heart disease in women with the increasing elderly population, and a national prevention policy is need to establish management of high risk by considering the age-period-cohort effect.

India has had a rich and diverse textile tradition since the 3rd millennium BCE. The origin of Indian textiles can be traced back to the Harappan period. Owing to the hot and humid climate in most parts of India, cotton has remained India's favourite choice of fabric for normal use. Thus, India is supposed to be the first nation to have grown, woven, and patterned cotton fabrics. Moreover, India is one of the leading cotton-growing countries in the world. The earliest occurrence of cotton thread in India is roughly datable to 4000 BCE and of dyed fabrics to about 2500 BCE. Large numbers of needles and spindle-whorls found in Harappa and other early historic sites in India reveal the prosperous state of textile production and its trade in the early period. The textile producers used a wide range of skills to process raw materials and make regionally idiosyncratic dyes, weaves, prints, and embroideries. Additionally, the silk from wild indigenous forms of silkworms was known in the Indian sub-continent roughly contemporary with the earliest clear archaeological evidence for silk in China. The analysis of thread fragments found inside a copper bangle and ornament from Harappa and steatite beads from Chanhu-daro, have yielded silk fibers dating to 2500-2000 BCE. Apart from other products, cotton and silk textiles were important export materials from India right from the Harappan period. Actually, the sea-borne trade had played an important role in the economic growth and prosperity of the Harappan civilization. Several ancient seaports in the entire coastline of India played a vital role in the maritime trade during the Harappan period and cotton and silk textiles of Indian origin have been found in various countries. The contemporary writings and epigraphy have also attested to the vast maritime trade network of India and the export of textile materials. The paper discusses in detail the origin and development of cotton and silk textile production in India through the ages and its role in maritime trade networks.

This study was conducted to provide sustainable measures for conservation and management to protect valuable natural/ecological resources, offer differentiated quality assurance services for eco-tourism products, and explore measures for eco-tourism certification/designation systems. To achieve its goals, the study discussed domestic and overseas trends and literatures that concern eco-tourism certification/designation system and investigated case studies that were presently operational. A group of experts and a group of non-experts were surveyed separatedly to investigate the awareness of the national eco-tourism certification/designation system. The results from the investigation indicate that Europe, since the late 1990s to early 2000, has actively introduced a system that establishes and operates a dedicated institution, and European members have created a cooperation framework to formulate international partnerships and develop standardized assessment benchmarks to adhere to the goals of the system, the period for certification was designated from one year to five years, and renewals were granted based on periodic monitoring and reassessment. In Korea, from early 2000, the Ministry of Culture, Sorts and Tourism and other organizations have certified product quality and assessed travel products and national park tour programs. The certification period was established to be set between one and three years, and the vast majority were not reassessed. Upon investigating the results for awareness of national eco-tourism certification/designation system, a high number of respondents agreed with the need to establish a eco-tourism certification/designation system (90% of respondents), and the respondents cited eco-tourism quality assurance, conservation of value, means to maintain established institutions, and environmental education and information as reasons for needing a certification/designation system. In Korea, a certification/designation system for the eco-tourism industry is presently in operation, but the system regulates target institutions based on their characteristics. Therefore, this study proposes its suggestions via various categories, including designated institutions, designated purpose, designated subjects, designated organization, laws, regulations, and incentives.

Choledochal cysts have been associated with complications such as cholangitis, pancreatitis, and malignancy of the biliary tract. Recently, the incidence of choledochal cyst in neonate and young infant is increasing due to advances in diagnostic imaging. The aim of this study is to investigate the rationale of excision of choledochal cyst during the neonatal period. The clinical outcome and correlation between age at surgery and the degree of liver fibrosis were reviewed retrospectively. A total of 198 patients with choledochal cyst who were managed surgically between January 1985 and December 2000 at the Department of Surgery, Seoul National University Children's Hospital were included in this study. The overall outcome and the outcome of patients who were managed surgically during the neonatal period were compared. Correlation between age and the degree of liver fibrosis was evaluated by chi-square test and Pearson exact test. The mean age of the patients was 2 years 7 months (ranged from 5 days to 15 years). Mean postoperative follow-up period was 7 years 1 month (7 months to 20 years). The results are as follows. Twelve patients (6%) had postoperative complications, cholangitis (7), bleeding (4) and ileus (1). Eleven patients operated during the neonatal period had no postoperative complications. The positive correlation between age group and degree of liver fibrosis was statistically significant (chi-square: p=0.0165, Pearson exact test: p=0.019). The results support the rationale that excision of choledochal cyst can be performed safely without increasing morbidity in neonates.

The decrease in fatness of the Pacific oyster Crassostrea gigas, which consequently results in decrease in the profit of aquaculture industry, has become a source of serious concern in southeast coast of Korea. The ratio of flesh (edible portion) to total oyster weight, commonly called edible portion yield ("suyul" in Korean), have been used as a fatness index for the healthy and valuable state of oyster from the early stage of oyster farming in Korea. More than 360 data sets were collected from early culturing periods (in the 1970s) to the present from approximately 15 published literatures to evaluate the long-term fatness trend of oyster, reared particularly in submerged longline culturing system in Gyeongsangnam-do province. Slight decrease in oyster fatness during the 1970s to 1990s was detected in Tongyeong and Geoje Bays; however, from the 1990s to the present, clear decreasing trends were observed with a decrease of 0.04-0.08% year^-1, especially during harvest season. Oyster mass production per unit area almost doubled within a short period in the early 2000s; however, changes in coastal environment factors inhibited the fattening of shellfish from the mid 1990s. These results indicate that the severe competition in feeding and low biological production in water column might be some convincing reasons for the decrease in fatness of oyster from the 1990s, in Tongyeong and Geoje Bays, Korea.

In search of the improvement plan for elementary schools which aims at the efficient application of new educational programs according to the introduction of the 7th National Curriculum, the analysis results for the spatial configuration regarding the modernized elementary schools in Busan City are as follows: 1) The analysis of expansion in the building area reveals that the building area per classroom has been increased from $200m^2$ in 1995 to $350m^2$ in 2005 based on the data gathered from the constructed schools during that period. 2) While the ratio of classrooms per the gross school area has been decreased from 35% in the late 1990s to 20% in the 2000s, the entire school size continue to become larger, which is considered as desirable change. 3) New construction and addition of special classrooms and multi-purpose spaces have continued to be increased. Multi-purpose spaces were positively considered in the early 2000s, but recently built schools tend to limit the construction of multi-purpose spaces only to lower grades' space or not to obtain them owing to the analysis that its utilization is limited. 4) Most schools constructed after 1999 are equipped with dining hall and multi-purpose halls, and show the increase in their sizes. Especially, dining hall tend to be located on the upper floors for better environmental conditions.

In the early 90's, we had serious shortage of construction engineers in Korea. The shortage was acute especially in construction quality control and supervision area, which were gaining social attention due to the road bridge and the department store collapse that took the hundreds of lives in the early 90's in Seoul, Korea. In order to meet the high demand of construction engineers, the engineering license regulations were changed in 1995. Engineers who did not pass the written exam but have equivalent working experience are given engineering license to practice engineering legally. Since year 2000, while the severe engineer-shortage has been resolved, the opposite situation has occurred: there is serious over-supply of construction engineers. Policy makers and engineering practitioners are agreed to bring back the old-fashioned written exam engineer licensing system like before 1995, i.e., no more written exam exemption. However, the engineers who obtained license without taking written exam may not want to go back to old policy which would take their license. It is required to provide appropriate grace period before the new policy takes effect to minimize the impact of the changes. This paper forecasts the supply-demand of construction engineers providing the basis for the most appropriate policy changes.
