Mathematical Problem solving has had the largest focus in the spread of mathematical topics since 1980. In Korea, most of the articles on problem solving appeared 1980s and 1990s, during which there were special concerns on this issue. And there is general acceptance of the idea that the famous statement "Problem solving must be the focus of school mathematics"(NCTM, 1980, p.1) in Agenda for Action, reflected in the curriculum of Korea. In a historical review focusing on the problem solving in the National Curriculum of Mathematics, we can infer that the primary goal of mathematics instruction should be to have students become competence problem solver. However, the practices of mathematics classroom and the trends of research in mathematical problem solving have oriented to ′teaching about problem solving′ and ′teaching for problem solving′. The issue of teaching via problem solving′ remain unsolved in the community of mathematics education and we need much more attention to this issue.

'중국학파'는 중국 애니메이션 학파의 약칭으로서 1950년대에 시작되어 1960년대 성숙기를 거쳐 1970-1980년대에 뚜렷한 성과를 거둔 중국 특색이 현저한 애니메이션 작품들을 가리킨다. 이 개념은 중국학파의 탄생, 발전 및 전성기를 비교적 정확히 설명하고 있다. '중국학파' 애니메이션은 중국 애니메이션 발전과정에서 큰 업적을 남겼으며. 본 연구는 그 성과를 고찰하여 성과의 내용과 의미를 찾아보고자 한다. 이는 중국 애니메이션산업의 종사자들에게 중요한 의미를 가진다고 본다. 본고는 주로 중국 전통 색채의 시각에서 애니메이션 조형에 대한 전통 색채의 영향을 고찰하고자 한다.

As the developing of the perinatal medicine, the survival rate of preterm infants are increasing. Viceversa the children with cercbral palsy is increasing also compare to the developing of the perinatal medicine The purpose of this study was to identify the relationship between the preterm infants and the children with cerebral palsy and their domestic circumstance in 1980 and 1990. And would like to introduce the way how to handle the children with cerebral palsy

The main purpose of this study is to evaluate the seismic safety of Korean R/C school buildings built in the 1980s, based on "the Japanese Standard for Evaluation of Seismic Capacity of Existing R/C Buildings", the nonlinear static and the nonlinear dynamic analyses. The evaluation result of the Japanese Standard showed that R/C school buildings built in the 1980s have 0.2 through 0.4 of seismic indices($I_S$). This result indicates that more than medium damage could be potentially occurred under a medium intensity level of ground motion(150g). The results of the nonlinear analyses and the post-earthquake damage evaluation method showed that Korean R/C school buildings can be suffered moderate and severe damages under a 150gal and a 200gal intensity levels of ground motions, respectively. These results reveal that R/C school buildings should be urgently required a actual earthquake preparedness measures including seismic strengthening for future earthquake.

The word 'Neo-Modern' means the revival of modernism, specially the concept of the White Geometry of Le corbusier and Mies van de Rohe, and the Neo-Modern movement in architecture indicates the leading aspects appeared in 1990's. Modern architecture was a formalistic art movement. With its historical roots, in Europe extending back to the avant- garde modern architecture in 1920's, Neo-Modern appeared with the name of New York Five, in 1970's. In Japan, there has been an outstanding movements presenting Modernism architectural charateristics, since 1980's. The characteristics of these works can be discerned from the those of Regionalism of Historicalism in 1980's. This study is to investigate and analyze the characteristics of the works of Japanese Neo-Modern architects and to contribute to defining the word, 'Neo-Modernism'. In chapter one, the background, purpose and methode of study are presented. In chapter two, the concept and historical background of 'Neo-Modernism' are studied. In chapter three, the characteristics of Neo-Modernism are studied on the basis of the main concepts and formal characteristics of modernism and New york Five. In chapter four, the tradition of Modernism inside the history of Japanese architecture were studied, specially focused on Metabolism. In chapter five, The characteristics of Neo-modern expressions used in the 18 exhibition and cultural facilities in Japan, established after 1980, are analyzed in terms of 4 expression categories. In chapter six, a synthetic conclusion is presented.

Water temperature in the eastern part of the Yellow Sea (EYS) during winter (JFM) and summer (JJA) from 1964 to 2009 and Siberian High Pressure Index (SHI) and Arctic Oscillation index (AOI) during winter (JFM) from 1950 to 2011 were used to analyze long-term variation in oceanic and atmospheric conditions and relationship between winter and summer bottom water temperature. Winter water temperature at 0, 30 and 50 m had fluctuated highly till the late of 1980s, but after this it was relatively stable. The long-term trends in winter water temperature at both depths were separated with cold regime and warm regime on the basis of the late 1980s. Winter water temperature at 0m and 50m during warm regime increased about $0.9^{\circ}C$ and $1.1^{\circ}C$ respectively compared to that during cold regime. Fluctuation pattern in winter water temperature matched well with SHI and AOI The SHI had negative correlation with water temperature at 0 m (r=-0.51) and 50 m (r=-0.58). On the other hand, the AO had positive correlation with Winter water temperature at 0 m (r=0.34) and 50 m (r=0.45). Cyclic fluctuation pattern of winter water temperature had a relation with SHI and AO, in particular two to six-year periodicity were dominant from the early of the 1970s to the early of the 1980s. Before the late of 1980s, change pattern in winter water temperature at 0 and 50 m was similar with that in the bottom water temperature during summer, but after this, relationship between two variables was low.

Gentrification, the revitalization of inner city areas, encompasses both the changes in social and demographic composition and the alterations in the physical and economic nature of built environment. This urban phenomenon has received the bulk of attention since the 1970s, and simultaneously provided one prominent stage for the theoretical or ideological debates in the field of urban geography. Given this context, this paper deals with the consumption-based and production-based approaches to gentrification, both of which are involved in such debates. Specifically, this paper critically reviews and evaluates David Ley's and Neil Smith's explanations representing the two approaches, respectively. On the basis of the two urban geographers' seminal works published in the 1980s, this paper discusses the limitations of each explanation as a partial explanation.

The austere standard for industrial design and the machine aesthetic reinforced modernism and lasted more than a half century. Pop art and Pop design movements, which were opposite of the elite culture, began to appear as anti-modernism in the late 1950s. With the development of technology, the movements helped to establish humanism design style that reflected the life style of young generation and their culture. From the 1960s. it was a try in order to fulfill psychologically users' needs beyond tasks for physical considerations. The efforts appeared as a various appearance in different contexts. It could settle down on industrial design, based on humanism both from the physical and psychological points ol views, through anti-modernism in the 1960s, commercialism, consumerism and hi-tech in the 1970s, and postmodernism in the 1980s. The design, as a specific style in industrial design, delivers both physical and psychological satisfaction to consumers by using a mixture of human emotions with high technology. Accordingly, this study is to find out and to define the design style that was applied by human emotion and sensibility in design history from the 1960s to the 1980s. It will be underpinnings for the next research about how the design style has developed nowadays.
