This study was conducted to develop functional muffin in which grape seed extract(GSE) was added at 0, 0.5, 1 or 2% levels and to evaluate the quality characteristics. The volume of muffin decreased with the increasing GSE content, but no significant differences were observed. The weight and height of muffins increased with the increasing GSE content. The incorporation of GSE in the product lowered lightness (L value) and increased redness(a value). The mechanical texture parameters including hardness, springiness, gumminess and brittleness increased with the increasing GSE levels. Sensory analysis showed that muffin prepared with 0.5% GSE was considered to be as acceptable as control, based on hedonic scale ratings given by untrained taste panel.

This research was to find out the effectiveness of the horticultural therapy program based on the therapeutic factors and the most meaningful experiences of the clients. For this purpose "Green harmony" program focused on harmony through horticulture was implemented. It is based on the preposition that holistic health is promoted with harmonious relationships with oneself, other people, community and nature. The program has three-fold structure: In innermost it deals with the task of the late adolescent, i.e., self identity, secondly the experience of communication and solidarity in the group, and finally extension of interest to the community. For the therapeutic intervention, questions using the metaphor of the activity were given to the clients for the establishment of self-identity, while group activity and the donation of the works let the second and third purpose accomplished. Outdoor activity, 'Tire garden project', has provided the clients with chances of the contact with nature, cooperation with other group members, and a contest to provoke enthusiasm. Also recycling and greening of the community were possible by utilizing old tires for the containers and by donating the final works to the community. For the evaluation of the result, the effect of the program on the stress of the college students was tested, and the most meaningful experiences during the participation to the program were asked to identify the therapeutic factors acknowledged by clients. "Green harmony" program has brought positive effects on the stress of the clients in spite of relatively short period of five weeks. The clients has acknowledged plant/nature contact and interactions between group members for the most meaningful experiences. This research suggests "Green harmony" horticultural therapy program based on the therapeutic factors is highly applicable for the general populations.

Horticultural therapy is a complementary therapy by trained professionals utilizing plant and horticultural activities as media to pursue the positive change of clients, which resulting from stimuli of plant․nature, activities, and interaction with other people. Outdoor horticultural activities provide clients with the opportunities of the contact to nature. such as fresh air and sunlight as well as plants. But the importance of plant․nature to client's health has not been fully acknowledged compared to that of therapist's role and activities in horticultural therapy in Korea. In horticultural therapy it is possible for client to participate on the various levels from passive viewing to active gardening according to the client's ability. Therefore it is necessary for horticultural therapists to consider the therapeutic factors of plant․nature to maximize the therapeutic effect of horticultural therapy. The purpose of the research is to clarify the therapeutic factors in the contact of client with plant․nature and to emphasize those importance in horticultural therapy. From the review of the experimental researches five therapeutic factors were revealed: Natural light, plant․natural view, natural sound, aroma(volatile oils of plants), and plant itself. This paper raises the importance of outdoor activities in horticultural therapy and the necessity for severely handicapped clients to the contact with plant․nature, though passively.

본 연구에서는 Mattson의 원예치료 원모델에 대한 분석을 통하여 모델의 합당성을 고찰하고 여기에서 나타난 제한점을 보완하여 원예치료시 식물과 원예치료사에 대해 대상자가 나타낼 수 있는 반응을 9가지로 세분하고, 각 반응을 하나의 원 안에 표현한 가설적 모식도를 제시하였다. 또한 이 모식도가 원예치료의 현장에서 실제적인 도움이 될 수 있도록 대상자가 식물과 원예치료사에 대해 나타낼 수 있는 부정적, 긍정적, 무반응에 대해 고찰하였다. 이 모식도는 원예치료의 초점이 되는 대상자는 원의 내부에, 원예치료사와 식물은 원둘레 위에 위치시키고, 원예치료가 진행됨에 따라 나타나는 대상자의 식물과 치료사에 대한 반응을 대상자의 위치변화로 표현함으로써, 원예치료과정 중 일정 시점에서 대상자가 어느 위치에 있는가를 시각적으로 제시하여 원예치료의 진행사항을 파악하고 원예치료사가 프로그램의 수정 및 보완 방향을 결정하는데 도움을 줄 수 있을 것으로 기대된다.

C8 ∼ 12의 medium-chain free fatty acid 및 1-monoglyceride의 다양한 미생물에 대한 항균력은 잘 알려져 있다. Lipid의 항균력에 대해 발표된 연구는 주로 사람이나 가축에 감염을 일으키는 병원성 세균 및 바이러스에 대한 항균력에 초점을 맞춰 왔으며, 실제로 화장품에 문제가 되는 미생물에 대한 체계적인 항균력 조사는 전무한 실정이다. 우선, 본 연구에서는 C12 (glyceryl laurate)에 비해 C8 (glyceryl caprylate) 사슬 길이를 가지는 1-monoglyceride의 화장품 제형 내 방부력을 조사해 보았다. 그 결과, C8 및 C12의 chain length를 가지는 1-monoglyceride 모두 세균에 대한 방부력은 매우 우수한 반면, 진균에 대한 방부력이 취약함을 확인하였다. 또한, C12에 비해 C8의 사슬 길이를 가지는 glyceryl caprylate는 항균력이 약간 우수하였다. 이 후 화장품 방부력 시험에 사용되는 5종의 미생물 각각에 대한 glyceryl caprylate의 항균력을 알아보기 위한 시험 결과, 그람 양성균인 S. aureus와 이스트인 C. albicans에 대한 항균력이 매우 우수하게 나타났으며, 그람 음성균인 E. coli, P. aeruginosa 순으로 우수한 항균력을 나타내었다. 하지만, 곰팡이인 A. niger에 대해서는 다른 균에 비해 매우 취약한 항균력을 나타내었다. 따라서, 본 연구에서는 glyceryl caprylate의 화장품 방부제로서의 적용을 위해 A. niger와 같은 곰팡이에 대한 항균력을 높이고자 하였으며, 그 결과 glyceryl caprylate의 A. niger에 대한 항균력이 산성 조건에서 현저히 증가하는 것으로 나타났다. 또한, 7종의 다른 antimicrobial agent와의 병용을 통한 최적의 조합을 찾고자 실험한 결과, methylparaben과 조합했을 때 진균에 대한 항균력이 가장 좋아지는 것을 확인하였다.
