The increase of the impermeable area due to industrialization and urban development distorts the hydrological circulation system and cause serious stream drying phenomena. In order to manage this, it is necessary to develop a technology for impact assessment of stream drying phenomena, which enables quantitative evaluation and prediction. In this study, the cause of streamflow reduction was assessed for dam and weir watersheds in the five major river basins of South Korea by using distributed hydrological model DrySAT-WFT (Drying Stream Assessment Tool and Water Flow Tracking) and GIS time series data. For the modeling, the 5 influencing factors of stream drying phenomena (soil erosion, forest growth, road-river disconnection, groundwater use, urban development) were selected and prepared as GIS-based time series spatial data from 1976 to 2015. The DrySAT-WFT was calibrated and validated from 2005 to 2015 at 8 multipurpose dam watershed (Chungju, Soyang, Andong, Imha, Hapcheon, Seomjin river, Juam, and Yongdam) and 4 gauging stations (Osucheon, Mihocheon, Maruek, and Chogang) respectively. The calibration results showed that the coefficient of determination (R²) was 0.76 in average (0.66 to 0.84) and the Nash-Sutcliffe model efficiency was 0.62 in average (0.52 to 0.72). Based on the 2010s (2006~2015) weather condition for the whole period, the streamflow impact was estimated by applying GIS data for each decade (1980s: 1976~1985, 1990s: 1986~1995, 2000s: 1996~2005, 2010s: 2006~2015). The results showed that the 2010s averaged-wet streamflow (Q95) showed decrease of 4.1~6.3%, the 2010s averaged-normal streamflow (Q185) showed decreased of 6.7~9.1% and the 2010s averaged-drought streamflow (Q355) showed decrease of 8.4~10.4% compared to 1980s streamflows respectively on the whole. During 1975~2015, the increase of groundwater use covered 40.5% contribution and the next was forest growth with 29.0% contribution among the 5 influencing factors.

Between 1980 and 1997 the Korean textile and clothing industry (KTCI) experienced the transformation of export-led accumulation regime rooted in domestically-derived price competitiveness into the combination between foreign mass production involving the geographical extension of productive forces and quality strategy based on upgrading technology and automation involved in the domestic market for high quality and price products. This restructuring of the KTCI is rooted at the crisis in the export-led growth regime implemented unity 1980 due to the rapid increase in wage levels by the ‘great labour movement’occurred in 1987. In particular, increased wage and collective bargaining realized through labour empowerment led to the crisis in the conjoin between mass production and mass export based on long working hours and low wage structure. The aim of this paper is to explore the transformation of development modes between 1980 and 1997 that can help us in understanding the fundamental reasons for the restructuring of the KTCI. To this end, the paper identifiles the changing accumulation regimes between 1980 and 1997 mediated by wage-labour relations, inter-firm relations and state-film relations, which are insitutional forms of the modes of regulation.

Asia has shown a tendency that a certain country's culture leads the fashion in turn every 10 years. The trend of Hong Kong movies in 1980's was called 'Hong Kong Wave', the trend of Japanese animation and games in 1990's was called 'Japanese Wave', and then the 'Korean Wave' began in the late 1990's. This term '~Wave(流)' is a Japanese-style term meaning '~way', '~style', '~group', and so on. In the same manner, recent popularity of Taiwanese TV dramas and a particular star that is in fashion in Japan are called 'Taiwanese Wave', and Chinese movies, broadcast, tourism, and etc. are called 'Chinese Wave'. Thus, the term 'Korean Wave' is a part of expression '~wave' used in Japan and it started to be used in the mean time, and was officially used in <韓流-Song from Korea>, a promotion record of Korean pop music, produced by Ministry of Culture and Tourism in Korea. In this paper I propose to correct the error of the term 'Korean Wave', and furthermore, to define a term expressing Korean culture and study for its usage.

This study aims to suggest the academic roles and direction of the social welfare for the elderly in Journal of the Korean Gerontological Society. For this purpose the trends of research on the social welfare for the elderly were analyzed by means of reviewing articles published from 1980 to 2008 in Journal of the Korean Gerontological Society. Out of all published articles, 215 articles were selected on the basis of unanimity among 3 reviewers including this author. First, in 1980s there were very limited numbers of articles. It had been mainly introduced foreign and domestic institutions of social welfare for the elderly and focused on the serious issues for the elderly in aging society. Secondly, in 1990s, there were explosive increases of research in elder welfare studies. The subjects of the articles were diversified and research methods were sophisticated in this period. Thirdly, it showed that the numbers, subjects, and research methods of the articles concerning social welfare for the elderly were enriched and differentiated during 2000-2004. Lastly, the research trends have focused on the issues of successful aging, quality of life, and psychological well-being in consideration of the quality of life for the elderly up to now since 2005. But the research trends have had some limitations in showing only application of theories and models or in simply introducing the knowledge in Western countries. It is necessary to have clear academic identity which can be faithful to Korean Gerontological studies.

본 논문은 우리나라 청소년 인구의 장기적 경제활동참여율 변동추이와 고용(실업)구조에 있어서의 변화에 관한 연구이다. 청소년층의 경제활동참여와 취업은 학교교육의 이수, 군복무, 결혼·출산을 통한 자신의 가족형성 등 일련의 생애전이과정(life-course transitin)과의 긴밀한 연계속에서 이루어지며 따라서 집단적으로는 연령단계에 따라서 큰 변화를 보인다. 본 논문에서는 먼저 지난 20여년간(1980년대-1990대) 청소년층의 연령단계별 경제활동참여 및 취업률이 어떻게 변화해 왔는가를 살펴본다. 청소년기에는 학교에서 노동시장으로의 진입과정(school-to-work transition)을 포함하고 있기 때문에 청소년층의 경제활동참여율 및 취업률은 무엇보다 동 연령집단의 취학률 및 진학률의 변화와 직접적으로 연결되어 있다. 본 논문에서 제시되는 자료에 의하면 지난 20여년간 우리나라 청소년층의 고등학교 및 대학진학률은 지속적이고 급격하게 상승하고 있었던 것으로 나타나고 있으며, 따라서 이러한 변화가 그들의 경제활동참여율 및 고용구조에 있어서의 변화에 미친 영향을 경험적 자료를 통하여 살펴본다. 1980년대 초반이후 우리나라 학교교육체제에 있어서의 변화가 청소년층의 취업구조에 미친 가장 주요한 영향 중의 하나는 높은 대학진학률에 따른 청소년 노동력의 고학력화와 그에 따른 고(高)실업의 문제이다. 본 논문에서는 사회구조적 요인과 고실업을 낳는 노동시장에 있어서의 불평등한 기회구조에 관한 이론적 논의와 경험적 증거들을 제시한다.

In 21st century as a digital era, visual communication design becomes more important than any other period. Recently, traditional typographic design for the communication with emphasis on the readability and experimental typographic design with emphasis on the expressionism contrary to the traditional concept coexists. There have been experiments on the typography with the establishment of modem art concept in the past: this trend is more obvious since the 1980s with the technological development of desktop computer. In this study, experimental typography works by David Carson who is one of the most representative graphic designers of the 1990s are analyzed in detail, and problems and prospects of this experimental typography in a digital era contrary to the traditional viewpoint we discussed.

Modern fashion shop is changed by the changing of fashion style. And as purchasing pattern is changed to consuming pattern which has strong individuality, functions as space which reflet characteristics of products and consumers in order to present sensitive and individual image are also required, besides conventional concept as space which simply focused on sale. Meanwhile, in the 1980's, the fashion presented retro mood modernly by popularization of post-modernism and introduced minimalism that is one of the anti-cultures in the 1960's. Recently minimalistic trends which are expressed by various attempts and a new point of view are introduced to the fashion shop by interior designer. Therefore, in this study, minimalistic characteristics which appear in the composition of interior space of the modern fashion shop are researched by theoretical consideration and analysis of examples and consistent direction of fashion shop is presented.

This paper is an anthropological study on the regional revitalization movement by the traditional ceramic industry in Mashiko-cho, Japan. It especially deals with the issues like history of revitalization based on ceramics, idealogical features and roles of core activist group, and adaptive strategies of local society to the ever-changing circumstances. The ceramic industry of Mashiko-cho had developed vigorously in 19C, and had passed many critical points in 20C. In 1960s, the ceramic industry of Mashiko-cho developed stably through introducing of Mingei(民藝) ideology and artists. This is evaluated as a 'bottom-up' regional revitalization movement and a active utilization of traditional cultural resources. In Mashiko-cho, the ideological leadership of cultural artist groups have been central roles in the regional revitalization movement. The representative cases are transformation of production of ordinary ceramics to production of Mingei ceramics from the middle of 1950s, official organization of core activist group and establishment of direct sale system by the producers in the middle of 1960s, and full-scale cooperation of private sector and public sector from the beginning of 1980s. Nonetheless the regional revitalization movement by the traditional ceramic industry in Mashikocho have come out well up to now, it should make new tradition which is well-matched to the ever-changing circumstances as seeing various and complex differentiation on the inside of local society.

The commercial value of the Korean animation was developed by the government's policies of revitalizing reform and national harmony from 1960 to the middle of 1980. Especially, the character of the anti communistic animation was organized by the structure of confrontation between South (good) and North (evil). The confrontation was viewed by communism and liberal democracy by red and white (or blue) and a pig or a boy. Such ideology and the policy of Korean culture gave some impact on its culture, for example, movie and animation. The animation became the tool of educating the idea of anti-communism and the policy of Korean culture by firming the policy of anti communism. But that animation of anti communism must not be blamed because it is a general animation of Korea which describes the reality. We have to take a hard view of the time and reconsider it by the new point of view.

Purpose : The purpose of this study was to evaluate the timing of sexual maturation and secular trends of menarchial age in Korean adolescents. Methods : Nine hundred eighty two school students and 119 university female students were included. Tanner's pubertal assessment method was applied using a self-assessment sheet with pictures for their developmental stages. A medical checkup database from 1,156,022 women was also used to analyze the age of menarche from the year 1900 to 1980. Results : Onset of puberty was at $11.3{\pm}1.3$ years(y) in girls and $12.1{\pm}1.5$ y in boys and total pubertal duration was 3.6 y in girls and 3.3 y in boys. Height at the onset of puberty was $146.1{\pm}7.9cm$ in girls and $152.7{\pm}9.8cm$ in boys. Weight at the onset of puberty was $39.3{\pm}6.9kg$ in girls and $47.7{\pm}14.4kg$ in boys. The mean age of menarche was $12.0{\pm}1.0y$ and mean age at nocturnal emission was $12.3{\pm}1.8y$. By age ten, 3.0 percent of girls experienced menarche, which increased to 41.1 percent by age 12, and 98.0 percent by age over 15. By SMR 2 breast stage, 18.2 percent of girls experienced menarche, which increased to 66.1 percent and 91.7 percent by SMR stages 3 and 4, respectively. By SMR 2 pubic hair stage, 52.0 percent and by SMR 3, 93.8 percent of girls experienced menarche. While the menarchial age of women born around 1980 was $12.4{\pm}1.1y$, the menarchial age of women born around 1990 was $12.0{\pm}1.1y$. Age at menarche has been advanced approximately by 2 years between 1900 and 1980 birth cohorts. Conclusion : There was a downward secular trend in pubertal timing. Age at menarche has been advanced by 2 years during the last 80 years. Further large scale, prospective studies, including inspection by specialists, are needed to provide reference data for pubertal timing in Korean adolescents.
