The objective of this study is to review previous research on the role of the media in multicultural U.S. society and to characterize the research tradition. The study particularly focuses on arguments about the representation of race and gender. First, previous studies on ethnic minority media and mainstream media in the U.S. are reviewed. Ethnic minority media has remained an important research subject since Robert Park's immigrant press study, but previous studies overwhelmingly focused on majority media. Many researchers have in particular explored the representation of "race" in Hollywood films, television programs, and advertisements by using quantitative content analysis methods as well as qualitative textual/discourse analysis methods. Second, previous studies on the representations of "Asians," "Japanese Americans," and "the Japanese" are reviewed. Mainly due to efforts by Asian American researchers, empirical studies on the representation of Asians began to increase in the 1980s. These studies showed that the representations of Japanese Americans and Japanese people have been constructed and reconstructed as a part of the popular images of the "yellow peril" and the "model minority," which were constructed to represent Asians and Asian Americans. At that time, media researchers also began to explore the "interlocking system" of "race" and "gender," as it became a critical issue in feminist studies. Under the influences of cultural pluralism/multiculturalism, feminism, and postmodernism, media researchers in the U.S. came to explore more racial categories, such as Blacks as well as Asians and Hispanics, more gender categories, such as men as well as women, and wider contexts, such as images and texts as well as dynamic processes between cultural production and representation. In other words, their research perspectives have become pluralized and diverse.

本研究は，東日本大震災直後のゴールデンタイムの報道時間に着目し，分析を行った．その結果，2011年3月13日から通常の娯楽等の番組編成に変わったことが確認された．また，その後の特集番組では，全て池上彰氏による震災関連の解説であることが分かった．
今後の大規模災害時において，ゴールデンタイムには視聴者のニーズ，経営上の観点等，番組編成上の検討要素を考慮し，必要があれば娯楽等に迅速に切り替え，多様なステークホルダーのニーズに応えることが重要である．

本論文は、2010年の8週間の番組表データを用い、地上放送局とBSデジタル放送局のジャンル別番組編成を経済学の視点から分析したものである。分析の結果、NHKの地上総合チャンネルと在京キー局間、地上放送局とBSデジタル放送局間で重視する番組ジャンルが異なること、NHKのBSデジタル放送の各チャンネルは差別化されているが、3チャンネル全体では番組ジャンルの放送時間が平準化されていることが確認された。また、テレビ東京とBSジャパンを除く資本関係がある在京キー局とBSデジタル放送局間において、同じ時間帯で同じジャンルの番組が放送されるケースは非常にないことが明らかになった。

本稿では，メディア表現が及ぼす影響についての実証的な研究と，これまで問題になってきたメディア表現の特徴を整理した．青少年への影響については，暴力表現，性表現，反杜会的表現．言葉・思想関連表現のすべての領域で，青少年が影響を受ける場合があると考えられる．年齢別にみると，暴カシーンの影響に代表されるように，幼児や小学生など，低年齢の子どもたちのほうがメディアの影響を強く受けやすいことから，青少年保護のための配慮をする根拠はある．また，残虐な暴力表現，暴力的な性表現，飲酒，喫婢などの衣現，少数派集団に対する差別的表現，実在する人物，団体，病気などの名前が使われた場合に，杜会的な批判を浴びやすい．大人でも影響がみられる場合もあるので，表現にあたっては大人を対象としたメディアでも配慮が必要だろう．一方で，多様な人々を描くことは推奨される傾向もあり，配慮しながら，描いていく必要があると思われる．

The object of this paper is to provide some suggestions about the technological innovation science temporal lecture in Nagoya Institute of Technology in 2005. It was a unique lecture in terms of the following 3 points : 1) The lecture was not designed for graduated students of MOT course but for bachelor students in engineering. 2) The lecture was based on the case studies from history of Japanese industrial technology. 3) The lecture was focused on studying the vested or basic technology caused the technological innovation. It was shown that the lecture was useful for the students as an introduction of MOT and it also promoted a better understanding of manufacturing basic knowledge and engineers′ ethics.

This paper proposes a method to measure the effects of TV advertisements on the Internet bulletin boards. It aims to clarify how the viewes' interests on TV advertisements are reflected on their images on the promoted products. Two kinds of time series data are generated based on the proposed method. First one represents the time series fluctuation of the interests on the TV advertisements. Another one represents the time series fluctuation of the images on the products. By analysing the correlations between these two time series data, we try to clarify the implicit relationship between the viewer's interests on the TV advertisement and their images on the promoted products. By applying the proposed method to an Internet bulletin board that deals with certain cosmetic brand, we show that the images on the products vary depending on the difference of the interests on each TV advertisement.

This report is on a field research project involving Hi-OVIS (Highly Interactive-Optical Visual Information System) in HigashiIkoma, Ikoma City, Nara Prefecture. The purpose of this research is to discover how the lives of the people in the community have changed due to the appearance of this two-way interactive TV system. As a first step, this part of the research project was undertaken in order to clarify the process of acceptance by comparing the subscriber family viewing rate for a Hi-OVIS program with those of standard TV fare. The research involved 157 subscriber families. The program used was an interactive program titled "Let's talk." The survey was conducted from 7:55 to 10:24 P.M. on Saturday, November 25, 1978. The viewing rates were computed from data shown at one minute intervals on a display system within the Hi-OVIS Center giving the number of subscriber households tuned to various stations. The results definately showed that the viewing rate of subscriber families for the Hi-OVIS program was much higher than that for any individual regular TV station. Even though the survey was conducted during a Saturday night " time," when the regular TV stations broadcast popular programs with high viewing rates, the-people in the subscriber community were participating in the Hi-OVIS program. This fact indicates that the Hi-OVIS subscriber community is beginning to accept the new media, not as "present-day TV viewing" but as "a participatory communication media."
