This research allows purpose to investigate aspect of reading movement and reading education in the early period of the 1990's. This is succession research that is the Japanese Occupation Period, after release, the 1950's, the 1960's, the 1970's, the 1980's reading popularization movement research as current trend of opinion to examine modern reading popularization movement. Such series research that reading phenomenon analyzing comparison, is to find present address of reading movement and reading education. accordingly all sorts correct judgment about reading phenomenon, hereafter that will be foundation that unfold reading education more effectively. In main discourse first, investigated, reading movement, and second, observed classifying distinguish reading of student from reading of ordinary people by readers' interest etc.

In this paper, we deal with the teaching of algebra in the elementary school mathematics, and call this algebra teaching method as ‘early algebra’. Early algebra is appeared in the 1980's with the discussion of ‘algebraic thinking’. And many studies about early algebra is in progress since 1990's. These studies aims at reducing difficulties in the teaching of algebra and the development of algebra curriculum. We investigate the background of early algebra, and justify teaching of early algebra. Also we examine the projects and studies in progress around the world. Finally through these discussions, we compare our elementary textbooks with early algebra, and verify the characters of early algebra from our arithmetic curriculum.

The election broadcast began utilizing virtual studios in the mid-1990s. In 1996, SBS's virtual studio was evaluated as an innovation in Korean broadcasting technology that introduced the world's first virtual studio. However, there have been cases where KBS and MBC named it a virtual studio and used it for election broadcasting. Various CG (Computer Graphics) case studies of election broadcasting have been conducted since the 2000s, but the initial research is inadequate. Therefore, this paper complements existing research by analyzing the cases of the mid-1990s when they actually started using virtual studios. Beginning with SMOCKEY (KBS) and MAGICII (MBC) in 1995, we presented the initial model of the virtual studio, and then with SBS Virtual Studio, each broadcasting company evolved into the names Dream Studio (KBS) and Space 21 Studio (MBC). As a result of the analysis, it was found that the election broadcast is a chart showing the data and the winning prediction, and that the election broadcast was the trigger to compose the story based on the introduction of the virtual studio. It is a form of historical research dealing with the value of the early virtual studios in this paper. It is meaningful to see the process of Remediation.

Purpose: The incidence of upper gastric cancer and especially the diffuse type have increased in western countries. The aim this study was to investigate the chronologic changes of the clinicopathological features and survival rates of Korean upper gastric cancer patients. Materials and Methods: 1,638 gastric cancer patients who underwent gastrectomy were included in this study and they were divided into two groups; the 1990's (1991~1999, n=987) and the early 2000's (2000~2003, n=651). We evaluated the differences of the clinicopathologic features and the factors that affected the survival rates by univariative and multivariative analysis. Results: The older age (>60) patients increased from 42.7% to 50.7% respectively. Being overweight (body mass index$\geq$23) also increased from 31.5% to 43.2%. For the pathology, the incidence of stage Ia gastric cancer increased (29.8% to 44.5%) and the incidence of stage IV gastric cancer decreased (23.5% to 11.8%). Yet there was no difference according to the WHO classification, Lauren's classification and the location of tumor between the groups. The 5 year survival rates increased 67.7% to 83.7%, according to the group. Multivariative analysis showed that the odd ratios of the early 2000s was 0.715 (95% CI; 0.555~0.921) as compared to that of the 1990s. Conclusion: There were no changes of the clinicopathologic features, like the pattern in western countries, although the incidence early gastric cancer, old age patients and overweight patients increased. The survival rate of early 2000s was better that that of the 1990s.

The purpose of this study is to analyze the characteristics of a life cycle of a theme park through looking at Everland in Yongin, Korea. The life cycle of Everland is divided into four stages. In "initial development" stage(1976 - the mid-80's), Everland become inclined the characteristics of an amusement park by constructing the amusement facilities in the Flower Center(botanical garden). In "growth" stage(the mid-80's - the early 90's), Everland had full grown to the amusement park and inclined to a theme park. In "maturity" stage(the early 90's - the mid-90's), many visitors were not motivated to re-visit Everland because the facilities and events did not change often. Therefore, Everland makes plans for multiple theme park. In "rejuvenation" stage(after the mid-90's), Everland has practiced the plans for multiple theme park and has become the family and accommodating-oriented theme resort park. Since 1976 when Everland was opened, it has evolved from an amusement park to a theme park by creating various and continuous innovations in facilities and events.

Regulation theory became a popular framework for economic geography in the mid-1990s but lost favor before it became prominent in South Korea. This paper revisits regulation theory - in both its original (1990s) and the revised (2000s) forms - to consider its applicability to the case of Korean capitalism. We contend that the difficulties in applying regulation theory to Korea are, on one hand, indicative of certain fundamental limitations in the theoretical approach and, on the other hand, useful for clarifying the distinctiveness of Korean capitalism.

This study analyzes the socio-economical contexts of Japan's Karaoke inflow in Busan of the 1980s, and examines the relationship between Karaoke culture of the 1980s and 'Noraebang' culture of the early 1990s in Busan from the perspective of the SCOT(social construction of technology) theory. By the end of 1970s, Japan's Karaoke was introduced under the contexts of structural transformations of a geisha tourism in the East Asian regions. Karaoke culture in Busan of the 1970s and 1980s has formulated social recognitions of the novelty of Noraebang culture in the 1990s, although it has done so through the ways of misunderstandings and Nationalism.

Wearable computer는 1980년대 중반부터 개발되기 시작하면서 1990년대에 들어서 본격적으로 개발이 진행되었다. 초기에는 컴퓨터의 각 부품을 분해하여 편리하게 배치하거나 신체의 됫부분으로 옮겨 조립함으로써 앞에서 보기에 보이지 않게 하는 정도의 매우 투박한 수준이었지만, 전자제품 생산기술의 발전이 가속화되면서 부품이 소형화되고 성능이 향상되면서 wearable computer의 기능이 크게 업그레이드되었다. 이러한 노력 덕분에 2001년도부터는 일상생활에서 착용이 가능한 수준의 디지털 의류의 형태로까지 개발되면서 언제 어디서나 네트워크에 접속하여 정보를 공유할 수 있는 유비쿼터스 시대를 향하여 나아가고 있다.(중략)

1980년대 산란 농가의 케이지는 대부분 A형이 주를 이루었으며, 1990년대에는 정부의 시설자금 지원이 본격화되면서 자동화$\cdot$대형화의 조류를 타고 외국산 직립식 케이지가 국내에 보급되기 시작하였다. 초기 직립식 케이지 설치로 평당 사육수수 증가가 가능했지만 자동화에 대한 지식 부족으로 질병과 생산성이 떨어지는 역효과도 있었다. 10년 이상 직립식 케이지에 적응하다 보니 노하우가 축적되어 대형 농장 위주로 직립식 케이지 설치가 증가하였고, 관리면에서도 안정을 보여주고 있다. 그러나 IMF이후 외국산 케이지를 설치하는 농가도 줄어들었고, 설상가상으로 정부의 시설자금 지원도 중단된 상태여서 외국산 케이지 보급이 소강상태를 보이다 최근에 와서 다시 설치가 증가하고 있다. 이와 관련하여 국내에 보급된 케이지 관리실태와 A/S현황을 알아보았다.

우리 나라는 각 대학이나 연구소에서 유능한 인력이 계속 배출되고 있고, 국산 기술에 대한 평가도가 날로 높아지고 있어서 레이저 산업의 전망이 대단히 밝다. 하지만 현재는 생산이나 수요 측면에서 모두 초기단계이며, 기술경쟁력도 선진국에 비해서 열악한 상태로 평가되고 있다.
