본 연구는 잔디 생육에 따른 그린스피드의 변화를 알아보고자 시행되었으며, 이를 위해 실제 골프장그린의 잔디밀도, 토양수분, 표면경도, 예고를 6개월 동안 매일 조사함으로써 그린스피드 향상을 위한 효과적인 그린관리 방법을 모색하였다. 연구결과 잔디밀도, 토양수분, 표면경도 그리고 잔디예고와 그린스피드 사이의 신뢰도는 각각 0.4742, 0.5690, 0.4632, 0.2806로 측정되어 토양수분이 그린스피드에 가장 큰 영향을 미치는 요소라 사료된다. 따라서, 잔디 생육에 지장을 주지 않는 범위라면 토양수분을 조금 낮게 유지하는 것이 그린스피드를 향상시키는데 유리한 환경이 될 것이다. 잔디밀도의 경우 그린업 시기이며 가장 활발한 생육기인 5~6월에 충분한 밀도를 확보할 경우 빠른 그린스피드를 내는 효과적일 것이라 사료된다. 표면경도는 롤링과 같은 관리 작업을 통해 경도를 높이는 것이 상당히 효과적인 방법이라는 점을 확인할 수 있었다. 다만, 롤링은 잔디에 높은 스트레스를 주는 작업이므로 정기적인 배토작업을 병행하는 관리가 좋은 대안이 될 수 있겠다. 그린예고와 그린스피드 신뢰도는 0.2806으로 토양수분이나 표면 경도에 비해 낮았다. 본 결과를 통해, 예고를 3.0 mm 이하로 낮게 관리하는 것은 그린스피드 향상에 도움이 되며, 시기적으로는 벤트그래스의 생육이 왕성한 시기에 예고를 조절하여 그린스피드를 관리하는 것이 유리하다는 점을 알 수 있었다. 하지만, 예고의 범위가 2.9~3.4 mm로 다양하지 못했던 상황을 고려하여 향후 좀 더 다양한 예고에서 그린스피드를 조사하는 연구가 필요할 것이다. 결과적으로, 잔디예고를 제외한 다른 세 가지 요소 잔디밀도, 토양수분, 표면경도는 그린스피드와 상당 수준의 신뢰도는 있는 것으로 조사되었으며, 잔디의 상태와 시기에 따라 각 요소가 독립적으로 그린스피드에 영향을 미치는 것으로 사료된다. 따라서, 관리자가 연중 높은 그린스피드를 유지하기 위해서는 시기별로 잔디생육 상태를 고려해 각 요소별로 집중 관리가 필요할 것으로 사료된다.

The primary objective of this research was to develop optimal models for masking the road traffic noise with the sound of a waterfall at urban small green spaces. Noise levels were measured at 8 roadside green spaces in SEOUL and questionnaires were randomly distributed to 40 users for evaluating the noise at each site at the same time. College students participated in the experiment for the development of masking models and the developed models were tested by users at 2 green spaces. The major results are as follows ; 1. Traffic noises ranged from 65dBto 70 dB. Users' satisfaction with the noise became considerably low on the basis of 60 dB and it was highly related to noise level. 2. Noise was a main factor to depreciate the amenity of green spaces where its level was more than 60 dB and so it neds to be excluded or reduced the traffic noise at the process of design. 3. Masking effects kept constant independent of the spatial location of masker on condition that masker levels were equal. It was effective when masker was 5-10dB greater than noise level which was masked. 4. As noise level went up, satisfaction ratings about the masked noise became low but masking effects increased in proportion to its level. 5. It was proved that the models were valid through the field experiment.

The accelerated pace of climate crisis due to continuous industrialization and greenhouse gas emissions necessitates sustainable solutions that simultaneously address mitigation and adaptation to climate change. Naturebased Solutions (NbS) have gained prominence as viable approaches, with Green Infrastructure being a representative NbS. Green Infrastructure involves securing green spaces within urban areas, providing diverse climate adaptation functions such as removal of various air pollutants, carbon sequestration, and isolation. The proliferation of Green Infrastructure is influenced by the quantification of improvement effects related to various projects. To support decision-making by assessing the climate vulnerability of Green Infrastructure, the U.S. Department of Agriculture (USDA) has developed i-Tree Tools. This study proposes a comprehensive evaluation approach for climate change adaptation types by quantifying the climate adaptation performance of urban Green Infrastructure. Using i-Tree Canopy, the analysis focuses on five urban green spaces covering more than 30 hectares, considering the tree ratio relative to the total area. The evaluation encompasses aspects of thermal environment, aquatic environment, and atmospheric environment to assess the overall eco-friendliness in terms of climate change adaptation. The results indicate that an increase in the tree ratio correlates with improved eco-friendliness in terms of thermal, aquatic, and atmospheric environments. In particular, it is necessary to prioritize consideration of the water environment sector in order to realize climate change adaptive green infrastructure, such as increasing green space in urban areas, as it has been confirmed that four out of five target sites are specialized in improving the water environment.

Recently, issues on the environment, which have become key bottlenecks relative to sustainable economic development, have generated common concern. However, relatively scant research has been devoted to consideration of relations between consumers' environmental concern, green fashion advertisement value, and green consumption. In this study, using structural equation modeling (SEM), effects of environmental concern, perceived green fashion advertisement value, and attitude towards green fashion advertisements, on ecological purchases and their interrelationships are investigated. A model is constructed to link aforementioned constructs. Data, was collected through a questionnaire-based online survey (www.sojump.com) of 260 Korean consumers and 260 Chinese consumers. Findings suggest that environmental concern can improve their perception of green advertisement value. One of the findings showed strong positive relationship among green advertisement value, positive attitude, and purchase intention towards green fashion advertisement, while environmental concern negatively influenced their attitude towards green fashion advertisements. It suggests that if companies adopt green advertising strategies, environmentally-conscious consumers are willing to pay more, to purchase green fashion goods in to satisfy their needs. We should put more effort in educating consumers about environmental issues, to raise the level of environmental awareness and satisfy their concerns relative to green fashion goods. Conversely, there is significant positive relationship with the moderating effect of consumers' nationality in all paths, so results above would make significant contributions to green literature, and would also contribute to advertisement strategy implications as well. Especially fashion marketers, an use accurate and fair environmental claims in their advertisements to increase sale and profits.

To achieve carbon neutrality and restore the national environment, there is growing interest in policies to transform national land areas into green space, such as expanding nature-based solutions, increasing biodiversity, and improving ecosystem service functions. In addition to complying with international agreements such as the United Nations Framework Convention on Climate Change and the Convention on Biological Diversity, it is necessary to expand green spaces to achieve the 2050 Carbon Neutrality goal, which can be achieved by restoring the damaged land in an ecological way. However, it is challenging to implement green restoration in a systematic and active way due to conflicts of interest among landowners and lack of institutional support and advanced technology. Therefore, this study aims to develop a strategy to expand green restoration and implement it smoothly and systematically. This study examined the current status of green restoration in South Korea by investigating green restoration laws and systems and overseas trends, and by surveying the perceptions of 1,000 people selected from a pool of the public. The results of this study show that it is difficult to implement the green restoration efficiently because the laws related to restoration are scattered. According to the relevant legal plans, the perception and direction of restoration is to pursue a sustainable national land environment, allow people to benefit from nature, improve the quality of life, and nurture related industries and human resources. In the international community, it is mentioned that green restoration contributes to achieving the 2050 Carbon Neutrality goal, revitalizing green industries, developing and applying advanced technologies, maintaining consistency in restoration-related policies, expanding citizens' access to green spaces, and adopting nature-based solutions. Both experts and the public are aware of the seriousness of the damage to the natural environment and prefer restoration with human use rather than focusing on natural recovery. It is expected that this study will contribute to the future direction of green restoration and the implementation of tasks for the sustainable restoration of the national land environment and the zero-carbon era.

In fashion history, the color "green" has been used from ancient to modern times constantly. Especially nowadays, the worth of green in fashion is becoming bigger than ever before to express the longing for pure nature. The purpose of this study is to define green's imageries in western costume history. For the basic about green, first of all, this study researched green of origin, effect and costumes in western history, then classified green's imageries. Green's imageries expressed in western costumes can be divided mainly into a 'nature imagery' and a 'religious divinity imagery'. Nature imagery was extended again into 'youth, devil, citizen and ecology image'. Youth image came from the luxurious feature of nature and it was extended again into 'innocent love, virgin and immaturity'. Religious divinity imagery has been represented in the ancient Egypt, Islam and Christian religion. In those cultures, green was considered as a sacred color of Osiris, Mahomet and Holy spirit.
