The aim of this study is to examine the changes of institution, quantity and approach methods of research results in the history of Korean economic geography during the last fifty-five years (1956-2010) and to offer the preparations for the future research. The history Korean economic geography can be divided into four periods: 'period of cradle' (1956-1962), 'period of establishment' (1963-later 1970s)', 'period of leap (the former half of 1980s-the former half of 1990s)', and 'period of transition (since later 1990s)'. Many departments of geography education and geography have been founded in the 'period of establishment' and 'period of leap'. Among the total research matters (1,621), 44.4 percent of research results have been made in 2000s and the most researched field was that of manufacturing geography, which occupied 27.7 percent. In the approach methods, about two-thirds of the results are the empirical inductive approach and the research frameworks method which clarified the regional structures and theory of spatial system occupied each about 40 percent. In the future, each research field of Korean economic geography is expected to take more serious view of nature environment, thorough regional survey, and preference of economy-society-culture-knowledge in the research framework of spatial network theory.

This paper analyzes the house designs of Kazuyo Sejima and Ryue Nishizawa from the 1900s to the early 2000s' works. By analyzing the degree of space integration of each house using the Convex Map of the Space Syntax Theory, this study arrived at the following conclusions in the respects of private space and public space. First, from period 1 (the 1990s) to period 2 (the first half of the 2000s), the differences between average integration values of private space and public space in their works have decreased. Over time, in general, average integration values of private space have increased, and, on the other hand, those of public space have decreased, leading to smaller differences between two sets of values, which means that, as the integration degrees of private and public spaces have become similar, the boundary which divides spaces becomes blurry. Second, in terms of private space, average integration values of private space in S-3 (House in a Plum Grove) and S-4 (House in China), works of period 2, are the highest among those values of their all 10 works. We can identify that, closure degrees of private space in their works have fallen over time. Third, in terms of public space, average integration values of I-2 (Villa in the Forest), I-5 (S-House), and I-6 (Weekend House), works of period 1, are the highest among those values of their all 10 works. Public space has become more central and open from period 1 to period 2.

Changes in fishing ground of the large pair trawler were investigated by year, month and species off Korean waters. We used catch data by sea-block lat.${\times}$long.:$30^{\prime}{\times}30$) of the National Fisheries Research and Development Institute (NFRDI) and monthly fishing production statistics of Korean statistic information service from 1990 to 2007. In the 1990s, the demersal fish like Larimichthys polyactis, Collichthys sp, Portunus trituberculatus and Muraenesox cinereus were the dominant species, and in the 2000s, they were changed from demersal fish into pelagic fish like Scomberomorus niphonius, Scomber japonicus, Engraulis japonicus and Todarodes pacificus. Species composition of catch showed temporal variation by cluster analysis deviding into 4 period, 1990-1994, 1995-2000, 2001-2003 and 2004-2007. Fishing ground in the 2000s was decreased up to 2/3 in the 1990s, while the density of catch in the fishing ground in 2000s was higher than the 1990s.

Objectives : Based on data collected from patients who suffered from dental caries during the period between 1990 and 2008, the number of patients and their trends were analyzed as a source of evidence to conduct the oral health plan. Methods : A population of sample design for patient survey data was derived from computerized data saved at medical institutions accredited by National Health Insurance Corporation. Large institutions such as dental hospitals were included for the complete enumeration test, while the rest of medical institutions, for example, dental clinic, relatively small institutions, were used for the sample survey. Most of patients with dental caries were outpatients and their disease was treated at the dental hospital or dental clinic in general, therefore, main analysis was carried out at those institutions. Results : The rate of patients who suffered the dental caries has decreased to 56.8% in 2008 from 78.5% in 1990. The rate of patients who visited the dental hospital for treatment has increased to 4.8% in 2008 from 0.5% in 1990, whereas the percentage of those who visited the dental clinic has fallen to 97.9% from 99.5% during the same period. The ratio by age, in the meantime, it showed that patients aged 40s has increased to 13.5% in 2008 from 7.2% in 1990, and the number also has risen in 50s from 5.6% in 1990 to 9.9% in 2008. However, the number of children aged 0 to 9 who visited hospital for treatment of dental caries has fallen to 17.0% in 2008 from 33.9% in 1990. Conclusions : By figuring out the trends of patients with the dental caries during the period between 1990 and 2008, fundamental data for the oral health policy have been collected. As a result, the necessity of a new medical treatment system for managing the dental caries in terms of patient ages as well as the oral health policy and campaign was taken into consideration.

The purpose of this study was to analyze the change in modes of expression represented in fashion illustrations between the 1910s and the 1990s. 639 fashion illustrations were analyzed by content analysis and by qualitative analysis in five aspects. Typical traits in the modes of expression infashion illustrations in each period were described. The outstanding transformation in modes of expression from "before'70s" to " after'70s" were confirmed. The findings support two hypothesis: that modes of expression in fashion illustrations evolve and that changing modes of expression in fashion illustrations is a reflection of "spirit of the times".uot;spirit of the times".uot;.

The purposes of the study were (1) to analysis Korean traditional wedding costumes through families's wedding photographs from 1940 to 2000, and (2) to categorize bride and groom's costumes according to the wedding time by means of a time series analysis. (3) to find out functional relationship among changes in garment types, garment details, embellishments and colors. The study was a documentary research and data were collected from 390 family wedding photographs by a convenient sampling. The data were analyzed by qualitative and quantitative method and the statistic used were frequency, content analysis, and cross-tab analysis. The results were as follows; First, the garments of wedding couples were categorized into 5 period according to garment's characteristics. 1. The period between 1940～1959 : Korean traditional wedding costumes and western style wedding costumes were existed together in Korean wedding culture. 2. The period between 1960～early 1970's western wedding costumes were dominated. 3. The period of late 1970's : wedding couple's costumes became more formal and decorative. 4. The period of 1980's : introducing see-through materials for brides and tuxedo suit for grooms. 5. The period of 1990's : extravagance in shapes and exposure. Second, there were significant relationships among brides's dress types and neckline, glove length, embellishments and transparency of materials and among groom's garment types and necktie types, types and color of shirts, vests. Third, the time series analysis of bride and groom's outfit produced 5 schematic expressions of wedding outfits according to the period.

The relationship between the Arctic Oscillation (AO) and surface air temperature (SAT) over Korea is re-examined using the long-term observation and reanalysis datasets for the period of December 1958 to February 2020. Over the entire period, Korean SAT is positively correlated with the AO index with a statistically significant correlation coefficient, greater than 0.4, only in the boreal winter. It is found that this correlation is not static but changes on the decadal time scale. While the 15-year moving correlations are as high as 0.6 in 1980s and 1990s, they are smaller than 0.3 in the other decades. It is revealed that this decadal variation is partly due to the AO structure change over the North Pacific. In the period of 1980s-1990s, the AO-related sea level pressure fluctuation is strong and well defined over the western North Pacific and the related temperature advection effectively changes the winter SAT over Korea. In the other periods, the AO-related circulation anomaly is either weak or mostly confined within the central North Pacific. This result suggests that Korean SAT-AO index relationship, which becomes insignificant in recent decades is highly dependent on mean flow change in the North Pacific.

The purpose of this study is to investigate the chronological characteristics of the strategy for the house marketing in terms of the apartment lots for sale advertisements appeared to be from 1970's to 1990's in Busan·Kyungnam area. For the analysis of the newspaper advertisement, a new residence environmental indication is introduced to this research as referring to the existing research data. With this indication, therefore, this study is to examine what contents of the advertisements are. Moreover, as analyzing how frequently the advertisements have been inserted in the newspaper, it shows the characteristics which the construction industry has planned for sale of apartment in lots. The results are as follows; First, the frequency of the appearance in the newspaper about each unit and block in an apartment complex has been on the decrease. On the other hand, the importance about the surrounding area has been on the increase during the period. It shows that consumer require more about the surrounding area issues than each unit itself. Second, in the case of the outdoor space in the apartment complex, the frequency of the appearance in the newspaper has been kept a certain levels during the period. It is clear that the consumers have been concerned about the outdoor space throughout the period. Third, the most important issue is the qualify of site location, such as the benefits of the traffic, the levels of the education environment, the natural environment of the apartment complex and so forth. The frequency of the appearance in the newspaper has been kept increasing since 1970's in the advertisement. It clearly shows that this issue has been standardized for purchasing a house.
