The article is to describe the recent phenomena in the area of American culture and religion such as multiculturalism, popular religion, and civil religion. It is also to evaluate those phenomena from the viewpoint of a missiological perspective. Multiculturalism is defined as all kinds of activities which try to support the various cultures and heritages of ethnic people groups and to overcome ethnocentrism. It is criticized by the conservatives as a political theory which tends to lose its truth, universality, and objectivity. From the missiological point of view, it can be used for developing the multicultural strategies for Christian missions. Popular religion exists outside the official religious institutions and it is related to the folk beliefs such as dream, charisma, trans meditation, channeling, angels, faith healing, and etc. It is criticized by Neoorthodox theologians that it tends to neglect the historical and political aspects of the social phenomena. Even though it is criticized by them as syncretism, it can be helpful for Christian missions to understand people's popular lives. Civil Religion is to respect the virtues and values of American citizens which are traced to Christian values such as temperance, private assets, individual responsibility, and patriotism. It is criticized as an ecumenical Protestant tribalism which tends to be misused by the imperialistic expansionism to destroy the cultures of minority. From the perspective of Christian missions, it should transform its selfishness into the world brotherhood in the 21 st century of the universal and multicultural world.

This study provides a national examination on youths' 'understanding' of irradiated food. The 1,200 subjects of the survey were randomly sampled from male and female students throughout the nation, between grades five and eleven. The survey was conducted toward these samples in November 2000. The number of respondents with exposure to irradiated food was so small, amounting to only 4.0 percent of the whole sample. The core concept used in this study is 'impression'. An impression is information about a specific subject, which carries significance to an individual. The results show that the higher the grade was, the more value the contents of impression contained. Furthermore, impressions concerning atomic or nuclear energy, and radioactivity increased greatly among students in middle school and above. Providing information of effects and advantages of irradiated food was focused to increase positive impressions and decrease the negative ones more greatly than providing simple factual information. Youths showed less value-centered impressions of irradiated food and more impressions centered on fragmented facts than adults. Respondents previously exposed irradiated food were shown to acquire the most of their information from the television and newspaper media. Among six information sources presented in the survey, youths pointed out 'science and technology research institutes' as the most credible. International organizations and environmental/ consumer organizations were evaluated as having relatively high credibility. Providing simple factual information of irradiated food did not seem to bring about any difference to the intention of purchasing irradiated food. On the other hand, respondents provided with effects-included information showed an increase in such intention. Our research results of the youth show a notable difference with that of the adults. Thus, programs and strategies to enhance youths' understanding should differ from those concerning adults.

The main purposes of this study are to know the contents and forms of impressions that the general public, and the consumerists and environmentalists have of irradiated food, and to know what information of irradiated food influences their impressions. Other purposes are to know what sources those impressions derive from, to know which media they have recently been exposed to and paid attention to irradiated food through, to know which sources they trust of information regarding irradiated food most greatly, and finally to suggest policies and strategies of communication in order to shed positive impressions of irradiated food on people. This study was conducted through the person-to-person interview survey toward 1,200 adults, and 150 consumerists and environmentalists in 1999. Adults are sampled nationally in South Korea. Only 8.7% of the general public have heard of irradiated food. Impressions of irradiated food that the general public mentioned most frequently are: harmful, insecure, negative, etc. The consumerists and environmentalists were found to have the most inaccurate knowledge of irradiated food. Television and newspaper were the major sources of impressions of, exposure to and focus of attention on irradiated food. Based on these results, we seem to devise methods to enhance impression of irradiated food by disseminating information of advantages and benefits that irradiation provides food with and to promote the fact that irradiation on food is totally irrelevant to being radioactive, danger of a nuclear power plant, genetically modifying food, etc.

Occupational science, stemmed from occupational therapy, is a new basic social science defined as the systematic study of the human as an occupational being. Mary Reilly argued that occupational therapy profession should reorganize its academic structure of knowledge by embracing traditional emphasis on occupation. Supporting Reilly’s view, Elizabeth J. Yerxa and her colleagues developed a doctoral program in occupational science with suggestions that the basic science (occupational science) of occupation should focus on the explanation of occupation, whereas the applied science (occupational therapy) should emphasize advancing knowledge on the use of occupation in treatment. The priority of occupational science is to promote theories about the form, function, and meaning as well as the sociocultural context of occupation so that the profession of occupational therapy can be nourished. The major contribution of occupational science to occupational therapy will be providing a body of knowledge sharply focused on the concept of occupation which will help in justification and enhancement of occupational therapy practice.
