目的 本研究は，大学生を対象に，喫煙行動，未成年者を取り巻く喫煙に関する社会環境，喫煙健康被害についての知識などに関する調査を実施し，大学生の喫煙行動に関連する要因を喫煙行動別および性別に探ることを目的とした。
調査方法 2002年の 4 月および 9 月に，関東地方にある 5 大学の公衆衛生学関係の講義に出席した学生を対象に行った。調査対象数は1,052人で，男性341人（32.4%），女性708人（67.3%），未記入 3 人（0.3%）であった。有効回答率は98.6%であり，1,037人の結果について報告した。
結果 20歳未満の男性の喫煙率は24.7%，女性では11.9%であり，20歳以上の男性の喫煙率は40.7%，女性では19.4%であった。
 日本は未成年者を取り巻く喫煙に関する社会環境が悪いと考えている男性学生は90.0%，女性学生は96.6%であり，女性の方が高かった。中でも，未成年の喫煙に「タバコ自動販売機の設置」が原因であると指摘した学生は約90%であった。
 未成年者の喫煙は成年より健康障害が大きいと考えている者は，男性より女性の方が多く，喫煙者よりも非喫煙者の方が多かった。
 健康日本21のタバコについての目標値のひとつである「未成年者の喫煙率を2010年までに 0%とする」に関する知識を有する者の割合は，3.5%と非常に少なかった。
 テレビの喫煙シーンが未成年の喫煙に影響を与えると考える学生は，喫煙者より非喫煙者の方が多かった。テレビの喫煙シーンへの関心については，喫煙者では「それ程多くない」，非喫煙者では「今後減らすべき」を選択する学生が多かった。
結論 タバコの有害性については，中学や高校で学習しており，一般的知識は有しているが，「未成年者喫煙禁止法」の意味する未成年の喫煙が成人より健康への被害を大きくすることや，健康被害の詳細な内容についてまで熟知している学生は多いとはいえなかった。とくに，喫煙者は非喫煙者より，未成年者への喫煙の健康被害を過小評価していた。
 また，喫煙者は，テレビの喫煙シーンが未成年の喫煙に影響を与えることは少なく，喫煙シーンもそれ程多くないと考えている者が多い傾向が認められた。

The purpose of this research is to investigate the type of speech acts young people use when evaluating others. It is necessary for foreign students living in Japan to communicate with Japanese students and they need to understand how the Japanese students communicate each other. The trend of how they communicate can be seen based on the speech acts they use while evaluating someone. However, the speech acts they use are complicated that it might be a trigger of a friendship discord. Therefore, this research is to clarify the popular speech acts types. The speech acts were divided into four groups following Brown and Levinson's “politeness strategies” and it was proved that the young people tend to use positive strategies such as "jokes" or "empathy" speech acts.

There has been an increase in the number of Japanese people who disagree with traditional gender roles which has resulted in diversified male roles. Based on a nine-male-roles model, this study examined the chronological changes and differences in male characters as per their ages and relationships with the heroine in NHK’s morning drama serials known as “asadora,” which is a Japanese TV drama. Results indicated that the roles of middle-aged men evolved from “high communion” in the ’60s and ’70s, to “high social status” in the ’80s and ’90s, to “commitment to household responsibility” in the ’00s and ’10s. Meanwhile, young men’s roles evolved from “high agency” in the ’90s to “attentiveness to women” in the ’10s. Additionally, the heroines’ husbands, ex-husbands, male friends, and romantic partners demonstrated “low effeminacy,” “superiority to women,” and “attentiveness to women.” Conversely, the heroines’ brothers, sons, and neighbors demonstrated “psychological and physical strength” and “emancipation from emotional restriction and toughness.” Based on social changes in Japan, implications of this study and future prospects were discussed.

It was in 1953 that television broadcasting began in Japan. Television drama programs, ridiculed as "electric picture-story shows" at the time, have progressed with the improvement of television technology. However, it has not been well known that drama programs were produced live in the pioneering days and there has been little research that dealt with live drama production from this period. This thesis aims to clarify the significance and role of live drama production and broadcast in the history of television drama in Japan through analysis of words spoken by those with firsthand knowledge that are archived at the NHK Broadcasting Culture Research Institute.

The purpose of this study is to clarify the effect of media consumption in promoting affinity to Korea in Japan in recent years. In the first part of this paper we confirm the social and cultural impact of increasing consumption of Korean media products usually called “Hallyu” or “Kanryu.” Next, based on the social survey data, we investigate the basic distributions of variables: affinity to Korea, changing impressions, media consumption, direct experiences and knowledge of Korea. Lastly, using multivariate analysis, we examine the causal structure of these variables and the factors leading to a changing Korean image. The results show that while the Korean media products tended to promote affinity and a more positive image, these did not lead to greater knowledge about either the history of Korea or the contemporary situation.

The history of the research of mass-mediated culture in the Japan Association for Media, Journalism and Communication Studies is classified in five stages. In the first stage (1952-1969), studies of mass-mediated culture emerged as the study of television culture and mass culture. In this period, the influence of broadcasting on human culture was highly controversial. In the second period (1970s-1980s), the study remained focused on television culture. Interdisciplinary projects involving anthropology, sociology, and folklore studies characterized the research of these years. During the third period (1990s), under the influence of British cultural studies, Japanese media studies began to include area studies, gender studies, and feminist theory. Transnational cultural exchanges and global communication also became important issues. In the beginning of 21st century, a fourth period saw studies of popular culture and subculture, rather than mass-culture, become the central focus of research, including manga, popular music, and mobile phone communications. The concept of mass-communication was no longer effective with the emergence of personal communication through the internet; no longer a passive audience of big media industry, individuals became active cultural creators. Thus, in the fifth stage of research (2010s), studies of fan culture as an active recipient and transnational fan communities as “girls culture” became a focus of research. At the same time, the mediated environment of museums and movie theaters also became a research topic. Through the seventy-year history of the association, studies of mass-mediated culture have primarily targeted the culture of ordinary citizens rather than the high culture of elites. Studies of culture have been and will remain an important genre in and outside of our academic society, for cultural activities are core to human identity.

当研究は2003年12月から約10ヶ月間に亘って行われた質問紙調査の結果を基に韓国ドラマ「冬のソナタ」の視聴行動と視聴者の韓国人に対する態度変容の関係について質的・量的に分析を試みたものである。分析結果から、参加者たちの韓国人に対するイメージは概ねドラマ視聴により好転し、彼らの韓国人に対する関心も高まっていることが明らかになった。偏相関分析の結果、主演俳優に好感を抱いたり、感情移入しドラマ視聴をすることと韓国(人)に関心を持つことの間に何らかの関連性があることが示唆された。また、重回帰分析の結果から、「韓国(人)に対する関心」「『冬のソナタ』への好感」「主人公への感情移入」などは韓国人のイメージの変化に比較的強い関連があるということが明らかになった。自由記述回答に対する内容分析の結果から、回答者たちは韓国の人々の倫理観、人間関係のあり方、ものの考え方などの様々な価値観、すなわち隣国の深層文化の一端を見、文化に対する理解をも深めた者が多く存在したことが判明し、日本での韓国ドラマの放映は、両国間の異文化コミュニケーションの観点からは望ましい結果を生んでいることが窺えた。
