Background and objective: Most cities in South Korea have mountainous forests as hinterland green space in their centers,which are used as urban parks. This study was conducted to analyze citizens' perceptions of a mountainous forestrestoration project being carried out in Jinju City. Methods: The research site is part of Bibongsan Mountain in Jinju City. Visitors' perceptions of the Bibongsan RestorationProject (BRP), carried out since 2015, were surveyed and analyzed regarding nature, history, and changes. The survey wasconducted from August to October 2019, and the collected data were statistically analyzed. Results: The main socio-demographic changes were an increase in the proportion of men among visitors, aging, and anincrease of unemployed people in the occupational distribution. The overall assessment of BRP implementation waspositive. Visitor perceptions of the value, revival, and restoration of historical resources were more vital than in 2015 andhad a strong positive correlation with each other. Visitors identified a high need for safety facilities for elderly visitors,improved wireless communication services, facilities for various recreational activities, outdoor learning facilities andprograms for nature study, expanded parking lots, and improved transportation services. Conclusion: The urban mountainous forest restoration project is overall satisfactory and needs to be continued. The resultsshowed that urban mountainous forests are not only recognized as spaces for walking and exercise for health but alsorecently as historical spaces expressing the unique or featured identity of the city, educational spaces for interest andunderstanding of nature, and recreational spaces that reflect local lifestyle changes. Thus, urban forests need to be restoredin the context of local historical and cultural resources as well as natural resources. In addition, there is a need to be awareof various changes in the population, including aging and an increase in retirees.

훼손된 산지의 복원과 이용을 위한 시민의식 분석: 진주시 비봉산을 대상으로

The purpose of study was to find critical problems which needed urgent solution and give policy priorities on the damaged forest lands close to cities through analysis of public perception. A survey was conducted of forest land users at the entrance of Mt. Bibongsan. And the survey consist of the questions of socioeconomic background on its nominal scale and the questions of cultural value, problem, solutions, maintenance methods and main body to drive related policies for the highly damaged Mt. Bibongsan on 5-point Likert scale. The 86.7 percent of respondents were in the over forties’ age and 65.3 percent visited the forest land more than two times a month. The early five categories’ averaged values were ranging from 3.54 to 3.89. Among the categories, ‘Solutions of the damaged forest land,’ ‘Mt. Bibongsan Restoration method’ and ‘Main body to drive policies’ showed statistical significance in their internal variables from Kruskal-Wallis test. But they did not show exact the ranking between variables and ranking. So thirty variables were reclassified to five categories (F1 ~ F5) by factor analysis. And with using this categories as dependent variables, five regression models were established respectively. The result showed that ‘Problem of Mt. Bibongsan (F1a)’ could be severer by illegal facilities and soil erosion from farming and ‘Solutions of Mt. Bibongsan (F1b)’ took the restoration of forest and destruction of aged houses on hillside as priories. For ‘Historical resources restoration (F2)’, it required to find folk tales and commune with citizen more from restoration of historical resources. To enhance ‘Mt. Bibongsan’s cultural value (F3)’, it was very important to consider citizen’s emotion linked to Mt. Bibongsan. As a ‘Main body to drive policies (F4)’, citizen’s active participation is more effective to policy enforcement. ‘Maintenance policy projects (F5)’ took restoration forest from farmland and forestscape improvement on city-viewed part as urgent projects.

Effects of Light Quality on Growth and Flowering of Hibiscus syriacus L. 'Blue Bird' at the Indoor
Heo, Keun-Young,Kang, Ho-Chul 韓國植物ㆍ人間ㆍ環境學會 1999 인간식물환경학회지 Vol.2 No.2
식물에 있어서, 빛은 단순히 에너지의 공급원일뿐만 아니라, 생육과 발달을 조절하는 신호를 제공한다. 특히, 광의 파장영역별 광량분포를 의미하는 광질(light quality)은 식물의 생육과 발달에 많은 영향을 미친다고 보고되었다. 따라서, 본 연구의 목적은 실내에서 무궁화(Hibiscus syriacus L. 'Blue Bird')의 생육과 개화에 대한 광질의 효과를 구명하기 위해서 수행되었다. 본 실험은 실내조건에서 인공광원을 이용하여 수행되었으며, 무궁화는 서로 다른 광질 특성을 나타내는 인공광원에서 생육하도록 하였느데, 광질(light quality)처리는 젤라틴 필름(gelatin film)을 이용하여 무궁화에 조사(照射)되는 인공광의 파장영역별 광량분포를 변화시키는 방법을 사용하였다. 실험중에 각처리의 PPF(photosynthetic photon flux)와 온도는 서로 균일하게 유지하였다. 각 처리에서, 파장영역별 비율(B: blue = 400-500nm; GY: green + yellow = 500-600nm; R: red = 600-700nm; FR: far-red = 700-800nm; T: 400-800NM)은 파장영역내의 광량으로 계산되었으며, phytochrome 광평형치(photoequilibria=Pfr/Ptot ratio)는 Sager 등(1988)이 기술한 식을 사용하여 산출하였다. 생육에 있어서, 높은 수준으 FR/T와 낮은 수준의 B/T는 식물의 크기를 증가시켰으며, 높은 수준의 R/T는 총신초길이를 증가시켰다. 높은 수준의 B/T는 엽장과 엽폭, 엽생체중, 건물증, 엽면적을 감소시켰다. �育�수준의 R/T와 GY/T, 그리고 낮은 수준의 B/T에서 잎의 색은 밝은 녹색을 나타냈다. 개화 반응에서 낮은 수준의 Pfr/Ptot는 개화기시를 앞당겼다.
