  • Catch data for the common squid (Todarodes pacificus), classified by squid-jigging fisheries per grid (size: $0.5^{\circ}latitude{\times}0.5^{\circ}longitude$), and the water temperature values KODC (Korea Ocean Data Center) were collected for the 1980-2009 period to study the changes in squid distribution and migration with climate regimes (1980s, 1990s, and 2000s). The primary fishing period in the 1990s and 2000s was approximately 2-3 months earlier than that in the 1980s. Especially in the East Sea, the fishing grounds in the 1980s stayed longer at high latitudes than those in the other decades. Moreover, in the 1980s, centers of the fishing ground were located near the Yamato bank (central East Sea), whereas in the 1990s and 2000s, they were situated near the southeastern coast of the Korean peninsula.

  • What is the socio-cultural meaning of the 1980s' Korean robot animations? What is the periodical backgrounds making this meaning? This study has attempted to lay the foundation stone of the answer for the questions. To do that, this study selected Roboteu King(Yeong-rang Bae, 1980) and Super Titan 15(Seung-cheol Park, 1983) as the objects of the textual analysis. To grasp the periodical identity, it has examined the cold war ideology that has been the basis of the political and economic environments of Korea. Findings are as follows. Korea was vulnerable to general environments after the Korean War; accordingly, Korea took the-dependence-on-the-US strategy in terms of various aspects including national security, scientific technology, and industry economy. This kind of socio-cutural condition was represented through the narratives of the early 1980s' Korean robot animations. Their narratives including the advance of plots, the roles of Korean protagonists, the technological gap between the planets and earth, and so forth were quite dependent on extraterrestrials and contained anticommunist ideology.

  • The purpose of this study was to investigate the difference in the trend of the study of elderly housing for the suggestion of the direction in Korea. This study was the first series about the study of elderly housing and analysed the 164 pieces of researches in Japan. The data were analysed classification with contents first, then examined the class in chronological order, and suggest the trend in the study of elderly housing in Japan. 1. The study of elderly facilities was reported the highest interest and was completed in the latter half of the 1980s except the payment elderly home in Japan. 2. Their second interest was the study of general elderly housing. Rural elderly facilities as a local elderly housing were researched frequently. 3. The study of housing for three generation was studied much in early 1980s, but decreased concerns these days. The study of housing for the elderly was studied the latter of 1980s and concerns were sustained. 4. Trend of the study of elderly housing was classified as follows; 1950s was the stage of unconsciousness, 1960s was the stage of sprout, 1970s was the stage of blossom, 1980s was the stage in full bloom and then the study was peak in 1986 and slowly decrease the concern. 5. In 1990s the study of elderly housing was moved into elderly facilities in a consumer's view and older people's life their family relation.

  • Since the 1980s the development of American art furniture was embodied its concept by second-generation furniture artists affected and educated from the first generation that has implanted art furniture fundamental values. Besides, embracing inevitably needs of the new era going with the social change rather than dwell on the nature of mere handicraft era, it has evolved with economic revival in the United States, the attention and increased consumption of the public, and ongoing government-sponsored. And more recently, the American contemporary Art Furniture faces another change in the non-boundary phenomena between art and design. American art furniture since the 1980s are summarized as three major trends: Art furniture embellished with traditional hand-craft, Art furniture featured the individualistic avant-guard characteristic, Art furniture eroded the distinction between art and design. By analyzing focusing on the furniture artists and their works in contemporary art furniture deployment aspects since the 1980s, the purpose of this study can be utilized as a method to measure the forward direction, internationally competitive, creativity, and artistic value of the domestic art furniture.

  • This paper analyzed romance novels imported into Korea in the 1980s and examined the traits of Korean girls' culture at that time. To this end, This paper chose as subjects the series of 'high-teen romance' published by Samjungdang, 'princess bestseller' by Seoul Publishing and the 'silhouette romance' by Joongang Ilbo in the 1980s. Through the aspects of the paperback romances, the traits of the artist, the content of the work, and the response of the reader, this paper analyzed the position and affection of romance as a genre in Korean culture in the 1980s. In the 1980s, most of the paperback romances available in Korea were translations of the modern and progressive present lines of Harlequin Enterprise's category romance. There were also many writers who were mostly introduced with progressive characters like Charlotte Lamb. The Harlequin romance depicts a story of sensual love. These translated 1980s paperback romance novels allowed girls in Korea to freely imagine the problems of sex and love. In particular, it showed a new perspective on women's sexuality. In Korean love novels, the sexuality of women was treated as an object for the gaze of men. The novels of female writers as college student who criticized this dealt with women's sexuality, but focused on criticism and resistance to the ideology of chastity. The paperback romance made it possible for women to freely enjoy their sexuality by escaping the ethical standards of reality. In addition, the paperback romance was an escape from the frustration of love. Romantic love in Korean love novels did not lead to the unification of mind and body, and always ended in tragedy. On the contrary, the paperback romance started with the fear of the girl who felt love for the first time, showed the process of winning over anxiety, confirming love and reaching a happy marriage. Through this, girls understood general love that was not subordinated to the ideology of chastity, and accepted love positively. The process of establishing romance as a genre in Korean culture and the traits of its readers have not yet been sufficiently clarified yet. This paper compared the romance genre with the other love novels of the day, explaining the position and meaning of the romance genre in Korean culture in the 1980s. Through this, we were able to chart the historical development of the Korean romance genre.

  • Oceanic conditions in walleye pollock habitat in the East Sea have shown decadal fluctuations between warm and cold periods in turn. Specifically, sea surface temperature (SST) has shown a dramatic increase between the late 1980s and the middle 2000s, and abrupt decreasing patterns after the late 2000s. Oceanic conditions in the Dong-han Bay (spawning ground) and middle eastern coastal waters (fishing ground), however, indicated different fluctuation trends in SST, increasing in the Dong-han Bay after the late 1980s, and decreasing after the late 2000s. These fluctuation patterns were especially clear in February and March. Sea surface temperature in the middle eastern coastal waters of Korea soared continuously after the late 1980s, but did not show a distinct decreasing pattern after the late 2000s compared with Dong han Bay, except for February SST values. These long term water temperature changes in both walleye pollock spawning and fishing ground are related to variation in walleye pollock landings. Especially, abrupt changes in spawning ground SST can be one of the factors influencing survival in the early ontogenesis of walleye pollock, including egg and yolk larval stages. During the 1980s, the area of suitable spawning temperature (2-5℃) was wider, and the length of Walleye pollock egg and larval stages greater compared with past and present oceanographic environments. However, such patterns did not correspond with the optimal spawning temperature range and greater length of development of walleye pollock during the late 1980s likely triggering a decline in pollock stock. In conclusion, it has been supposed that the dramatic decrease in walleye pollock landings in the East Sea since the late 1980s was caused by increasing water temperature leading to both early mortality and unsuitable spawning conditions.

  • This review paper discussed the decadal fluctuations in the catch of the common squid, Todarodes pacificus (T. pacificus) by focusing on migration and distribution patterns. Since 1980s, changes in T. pacificus catches were due to climate regime shift in Korean waters. Fluctuation patterns of catches were different between the East Sea and the Yellow Sea. Generally PDO (Pacific Decadal Oscillation) phase shows a negative correlation with strength of warm current to the East Sea. In 1980s when PDO was positive phase (+), T. pacificus catch was higher in the Yellow, but it was lower in the East Sea. In 1990s when PDO was negative phase (-), T. pacificus catch showed opposite trend compared with 1980s. Such spatial and decadal fluctuations of T. pacificus catch were due to its northward migration along with the warm current or southward movement against the current. In the East Sea, strong (weak) warm current period, the current path has been shifted toward the East Sea coast of Korea (central East Sea or the coast of Japan). It has a correlation with PDO. In the positive PDO phase (1980s), the fishing ground was located on the eastern side of Ulleungdo, whereas during negative PDO phase (1990s), they were situated near the southeastern coast of the Korean peninsula. In the 1980s, volume transport passing into the Yellow Sea increased, whereas volume transport in the East Sea decreased. This is one of major reason increasing T. pacificus larvae in the Yellow Sea.

  • The so-called Cultural and Historical Geography, sometimes called even as the Historical and Cultural Geography, has been defined as an interdiscipline that encompasses several disciplines in Korea. Scholars with various academic background have participated in the academic activity of the Association of Korean Cultural and Historical Geographers that was organized in the late 1980s. The academic majors of these participants are cultural geography, historical geography, history of geography, urban geography rural geography, economic geography, social and economic history anthropology, landscape architecture, and so on. It was in the 1960s that articles about the Cultural and Historical Geography appeared for the first time in the major academic journals in Korea. The pioneers of publishing these articles in the 1960s continued to conduct their research, while training students majoring in the Cultural and Historical Geography in the 1970s. All of these pioneers and their students were very active in the formation of identity vrith the Cultural and Historical Geography In the 1980s. Cultural and Historical Geography in Korea took a great leap forward both in quantity and in quality. The number of articles in the journal increased substantially, and the range of research theme and methodology extended in a great deal. It was also in the late 1980s that the Association of Korean Cultural and Historical Geographers was organized in Seoul, Korea, and this association began to publish a professional journal named Cultural and Historical Geography once a year. In the 1990s, single-authored books dealing with Korean Cultural and Historcial Geography began to appear in public as textbooks or research monographs. These books are expected to speed up the spread of Cultural and Historical Geography in Korea. If it continues to grow further both in quantity and in quality as it has been, Cultural and Historical Geography in Korea will be able to stand as an independent academic field in the future. Until then, however, it cannot but avoid its mission to contribute to an integrated development of human geography in Korea. It has already gained not only its own merit in the humanistic perspective but also its own strength in its synthetic understanding.

  • In this study, the characteristics and patterns of family problems were explored. What constituted family problems, and how those evolved over the period of drastic changes in the Korean society were examined, by analyzing articles published from the 1940s to the 1980s in the four major national newspapers in Korea. A total of 6542 articles related to family problems in the four newspapers, Chosun, Dong-A, Kyunghyang, and Seoul, were used for the content analysis of this study. The main categories of family problems were classified as poverty, marital issues, issues related to children and adolescents, elderly issues, problems in the family as an institution, and the so-called family-lag problem. Each of these categories consisted of several subcategories: The poverty-related problems included the problems caused by difficulty in making a living and instability of living, for example. The marital issues category consisted of conflicts between the couple, unfaithful spouses, domestic violence, divorce, and so on. Issues related to children and adolescents included juvenile delinquency, difficulty in bringing up children, child abuse, single motherhood, and underage household heads, for example. The elderly issues included the anxiety over the aging society, support for the elderly, conflicts between mother-in-law and daughter-in-law, alienation of the elderly, etc. Problems in the family as an institution consisted of the legal issues in such areas as marriage, succession of the family head, and adoption. Lastly, the family-lag problem included confusion over family values, and conflict caused by the inconsistency between consciousness and actual behavior related to the family or family crisis. From the 1940s to the 1980s, family-lag was the most common problem (26.2% of the total articles), followed by issues related to children and adolescents (23.1%), poverty (16.2%), marital issues (15.9%), elderly issues (12.4%), and problems in the family as an institution (6.0%). During the 1940s and the 1950s, poverty was a prominent problem, and in the 1960s, issues related to children and adolescents were most commonly addressed in the articles. In the 1970s and the 1980s, the family-lag problem was the most frequently addressed.
