  • ^x In Korea, we are entering on a new phase that the use concept of urban park is extending to dynamic activities such as games and sports. This article is to investigate the significance of lawn areas, as a receptive space of such a wide range of recreation activities. As a study process, Green Styles (type of parks) such as Garden Type, Park Type and Forest Type were studied and historical review of lawn areas in park development was performed. In conclusion, the lawn areas ( greensward) are an essential part of park and open space organization. The significance as a conclusion is presented as follows : 1 ) Balance in type of parks The structures of our parks and open spaces are inclined toward the artificial Garden Type and natural Forest Type. Therefore, the intermediate Park Type and sparse wood areas should be a core part of our park and open space development. 2) Psychological effect Park Type areas, thorned by greensward(lawn area), can refresh urban dwellers with natural picturesque landscaps, and Park Type landscape is the most preferred natural landscape. It shows the essence of natural amenity as 3) Accomodation of wide range of recreation activities Lawn areas in urban park are the best place in accomodating the wide range of active and massive recreation activities. Thus, lawn areas can increase the freedom of recreation use in urban park. 4) Enlargement of physical carrying capacity. With expansion of lawn areas of euro- american concept, the structural open space can be transformed into service open space. Thus, the recreation carrying capacity of urban parks can be enlarged.

  • The aims of this study were to examine the efficacy of phytochemicals of Rumex crispus as anti-oxidant and anti-browning agent. The bioactive properties of Rumex crispus as natural colorants were studied by total phenolic contents, DPPH radical scavenging, ABTS radical scavenging,lipid peroxidation, cell viability, singlet oxygen quenching and photoprotection effect. Among all of the results ($IC_{50}$: the concentration of various extracts required to exert 50% reducing effect), the higher activity of the extract was found in the ethyl acetate and butanol extracts. Anti-browning activity was evaluated by monitoring the change $L^*$, $a^*$, $b^*$ values and total color differences(${\Delta}E$). It was found that ethyl acetate and butanol extracts effectively inhibited browning in apple juice at a concentration below 0.3 mg/ml. Rumex crispus extracts used natural colorants could be of good resources as anti-oxidant and anti-browning agents. The results suggest that our study may contribute to the development of natural and functional materials with potential application to reduce oxidative damage.

  • 본 연구는 자연공원분야에 서비스스케이프의 개념을 적용하여 서비스스케이프가 탐방객의 지각된 가치, 전반적 만족 그리고 행동의도에 미치는 영향을 살펴보고자 하였다. 연구결과, 자연공원의 서비스스케이프는 주차장, 화장실, 휴식공간, 부대시설 등 공원 내의 시설을 중심으로, 공원까지의 접근성과 시설이용의 편리성 및 쾌적성의 3개 요인으로 측정할 수 있었다. 또한 탐방객들이 공원 내의 시설 즉, 서비스스케이프를 호의적으로 인지하면 무형적인 경험의 가치도 호의적으로 인식하게 되어 결과적으로 전반적인 만족과 행동의도에 긍정적으로 작용하는 것으로 확인되었다. 특히 탐방객들은 탐방경험을 통한 시간가치를 중요하게 인식하였으며, 이에는 서비스스케이프 요인 중 쾌적성이 영향을 미치는 것으로 나타나 자연공원의 관리적 측면에서 청결하고 쾌적한 환경조성을 위한 지속적인 노력의 중요성을 시사하였다. 본 연구는 자연공원에 서비스스케이프의 개념을 적용한 첫 번째 사례라는 점에서 의의를 지니며, 후속연구를 통해 연구결과의 일반화와 신뢰성의 향상이 요구된다.
