The Korean Society for Plants, People and Environment held its first International Symposium on Plant and People Interactions in Human Health and Quality of Life in May 1998. Three speakers, invited from abroad, were among those who made presentations. A summary is presented.

Through funding from various horticultural associations (including ASHS, ALCA, SAF, WFFSA, and HRI), the People-Plant Council has been able to develop a computerized bibliography that will be of great value to researchers in the area of People-Plant Interaction and a second bibliography specifically for the area of Horticultural Therapy. The combined PPI and HT bibliographies contain approximately 1600 citations, 25 percent of which include an abstract. Due to the size and length of each bibliography (over 200 pages of hard copy), they are available on diskette. This will facilitate users searching for keywords or specific articles and allow them to rearrange the material as needed.
Research on human issues in horticulture focuses on the human dimension of horticulture in an effort to maximize the benefits of plants and nature in general, for human well-being. A key issue is the need for scientific evidence of such benefits and for rigorous research methods to reveal the mechanics of the interaction between people and plants. Conjoint analysis, a methodology with obvious potential for successful application in the area of human issues in horticulture, is widely used in consumer research to estimate the structure of people's reactions to multi-attribute objects or services. This paper discusses the steps involved in implementing conjoint analysis and describes how it can be applied to people–plant research.
The plants of the bibles have long been of historic interest despite the many translation problems. The Hebrew bible was written in Hebrew and Aramaic, translated into Greek in the second century bce , and then constantly translated into all the

Conducting research with human subjects involves many of the same issues involved with conducting any type of research. As horticulturists, we are aware of the range of variability that can be introduced when working with living organisms. This variability can come from environmental influences as well as genetic variation. These can be major factors when conducting research with people as well. Research with people also introduces complicating interactions between the researchers and the subjects. When working with humans as subjects, federal regulations must be considered; these regulations are even stricter when the research involves youth. These additional factors, which should be considered when designing studies to understand the impacts of plants and plant programs on youth, will be discussed.

Quantitative evaluation of horticulture vocational-therapy programs is becoming more and more critical as professionals in the area of people-plant interactions try to document the value of their programs. Evaluation tools to assess self-development of individuals studying such factors as self-esteem, life satisfaction, and locus of control have long been used in the social science disciplines. Many of these tools, either in their original forms or with some adaptations, can be successfully used to measure changes in self-development of individuals participating in horticulture programs.
