Civic participation in managing the work of a park is a natural experience, and urban culture has a role in forming and communicating ideas. However, when it comes to managing a copse, there is no clear scenic image. In this study, my intention was to determine a desirable scene involving a copse and suggest a target image for managing work from a scenic perspective. I selected 12 photographs and listed 10 pairs of adjectives that were judged to reflect the effect produced by the copse scene using the repertory grid development technique. In addition, I performed a scenic evaluation using the semantic differential(SD) method with each pair of adjectives. Factor analysis was performed based on questionnaire survey results, such that the scenic structure of the copse had a clear definition. In addition, the physical characteristics of the photographs were analyzed using Adobe Photoshop 6.0 and the correlations between the results of the questionnaire survey were understood using multiple regression analysis. A desirable scenic image of the copse became clear through this process and I was able to suggest various options of scenic images. Taking the aspects of urban culture into consideration, park improvement projects(including their planning stages) should be implemented by involving residents, which will lead to further development of park planning and maintenance theories and projects giving due consideration to residents' opinions.

This study aims to understand how different construction methods impact scenic preference of green wall and clarify features of each construction method to help select the most suitable construction method for the wanted image of a green wall by providing the basic data for further development and distribution of green wall. Questionnaire developed by the Repertory Grid technique proved that 11 adjectives can be used to describe scenic features of a green wall and 4 preference elements. The result of the Scenic evaluation, the Felt type scored high in 'Aesthetic' and 'Maintenance' meaning that it is the most suitable method when constructing a green wall to improve urban scenery. Regression analysis was conducted to understand the link between the preference elements and scenic impression of a green wall. The result is that the higher the preference is on the design of a green wall, the higher the score is for 'Aesthetic'. Also, the higher the preference is on Bio-Diversity, Design, Growth, the higher the score is for 'Natural'. The above findings can be important measures and reference for selection of the right construction method when planning a green wall.

This paper aims to compare the scenic images of four ancient Chinese cities including Lijiang, Pingyao, Huizhou and Langzhong, so as to provide specific development strategies for the ancient cities. In this paper, the ancient cities' scenic images are divided into three sub-indexes and eight evaluation dimensions. Based on this, the study first uses Python software to collect tourists' online comments on the four ancient cities. Then, the social network analysis method is used to build a high-frequency keywords matrix of tourist comments and the R language is used to generate a visual network graph. After this, the entropy weight method is used to determine the weights and values of eight evaluation dimensions. Finally, the tourists' overall satisfaction indexes of the four ancient cities are calculated accordingly. The results show that (1) the overall satisfaction of Lijiang is the highest, while that of Huizhou is the lowest; (2) from the weight of each evaluation dimension, it can be seen that tourists care more about the national culture and historical culture; (3) from tourists' satisfaction index on each evaluation dimension of the four ancient cities, we can find that the four ancient cities has their own advantages and disadvantages in tourism development. (4) local tourism-related institutions should strengthen their advantages and improve their deficiencies so as to enhance tourists' overall image of the ancient city.

With the improvement of people's living standards and the development of tourism, tourists have greater freedom in choosing destinations. Therefore, as an indicator of satisfaction with scenic spots, tourist comments are becoming increasingly prominent. This paper aims to compare and analyze the landscape image of the Five Great Mountains in China and provide specific strategies for its development. The online reviews of tourists on the Online Travel Agency (OTA) website about the Five Great Mountains from 2015 to 2018 are collected as research samples. The text analysis method and R language are used to analyze the content of the tourist reviews, while the high-frequency words in the word cloud are used for visual display. In addition, the entropy weight method is used to determine the index weight and tourist satisfaction is evaluated to understand the weaknesses of those scenic spots. The results of the study show that firstly, the tourist satisfaction with the Five Great Mountains is basically consistent with its popularity. Secondly, through weight analysis, tourists pay special attention to the landscape features and environmental health of the scenic area, so that relevant departments should focus on building the landscape characteristics and improving the environmental health of the scenic area. At the same time, the accommodation and service management of the scenic spot cannot be ignored. Finally, according to the analysis results, suggestions are made on how to improve the tourist satisfaction with the Five Great Mountains.

본 연구는 고군산 선유팔경이 설정된 경위와 각 경점의 경관특성을 고찰한 것으로 요약된 결론은 다음과 같다. 첫째, 1969년 이래 설정된 경점은 수차례 그 내용과 순서가 바뀌었고 표제어 또한 일정한 변천과정이 확인된다. 70년대까지 알려진 팔경은 공식적인 팔경명이 없거나 고군산팔경으로 명명된 경우가 많았으며, 무산십이봉이 제외된 구성을 보인다. 또한 팔경의 경점이 시기별로 제각각인 유형도 나타나는데, 따라서 선유팔경의 초기 형태는 인근 지역의 팔경을 참조하되, 고군산군도 특히 선유도의 경승이 취사선택된 것이었음을 알 수 있다. 둘째, 현재와 같은 팔경 요소가 모두 충족되어 나타나는 2000년대 초의 선유팔경은 순번이 명시되어 있고 표제어가 네 글자로 정제되어 있어 전통적인 팔경의 명명법을 따르고 있다. 이때 제1경이 망주폭포로 설정되고 선유낙조가 제8경으로 구분되기도 하였는데, 현재는 제1경이 선유낙조, 제2경이 망주폭포의 순서로 확정되었다. 이러한 경처 순서의 변화는 시기별 대표 경관자원이 달랐다는 점을 잘 보여준다. 셋째, 정체성과 완결성이 약한 점은 선유팔경에 내재된 문제점으로 지적된다. 무엇보다 설정주체와 설정시기가 모호하며, 선행되는 옥구팔경, 임피팔경 등 인근 지역의 팔경사례를 답습한 흔적이 역력하다. 또한 경관대상에 대한 지식정보, 조망하는 시점의 명시, 역사·문화적 배경 등이 모호하여 정제되지 않은 불완전한 체계를 갖는 것으로 평가된다. 넷째, 제1경 선유낙조는 전체 경점을 대표하는 것을 넘어 팔경 전체를 지배하는 주도적인 이미지를 갖는다. 일시적 경관인 낙조가 제일의 경관이 될 수 있었던 것은 그것이 선유도의 아름다운 자연적 요소들이 융합하여 만들어진 경관의 총체로 인식되었기 때문이었다. 따라서 선유낙조를 기점으로 선유도 및 고군산군도 전체 경관을 탐색해 보고자 하는 기왕의 인식을 활용하여, 다른 고군산군도 경관자원의 가치 고양시킬 여지는 충분하다고 판단되며, 이를 위해서 각 경점의 정체성과 완결성을 강화하는 작업이 추가되어야 할 것으로 사료된다.

The population hasincreases in urban increase geometrically, and then many problemsoccur in society anomity, environmental pollution, exhaustion of recourses, So we have to consider the quality of our life. Eco-village is the alternative the village's principle to consider the human life. Eco-village refers to the application to ecological principles to the development of human ecosystem in order to achieve sustainability. Since a few yearsm, in Korea, ecovillages have built for alternative society and developed local society. The expert and residents live ecovillages just consider the physical system or the social system. However, Ecovilliges must have not only unique physical, social aspects, but also the scenic aspects, especially, in the villages for eco-tourism. The paper examines what images are recognized by the people as ecovillages, and what difference betweenr they understand the functions and meaning each image or not. Through the result, this paper explores the important and necessity of the scenic landscape plan in ecovillages.

Innovation and rapid increased functionality in user friendly smartphones has encouraged shutterbugs to have picturesque image macros while in work environment or during travel. Formal signboards are placed with marketing objectives and are enriched with text for attracting people. Extracting and recognition of the text from natural images is an emerging research issue and needs consideration. When compared to conventional optical character recognition (OCR), the complex background, implicit noise, lighting, and orientation of these scenic text photos make this problem more difficult. Arabic language text scene extraction and recognition adds a number of complications and difficulties. The method described in this paper uses a two-phase methodology to extract Arabic text and word boundaries awareness from scenic images with varying text orientations. The first stage uses a convolution autoencoder, and the second uses Arabic Character Segmentation (ACS), which is followed by traditional two-layer neural networks for recognition. This study presents the way that how can an Arabic training and synthetic dataset be created for exemplify the superimposed text in different scene images. For this purpose a dataset of size 10K of cropped images has been created in the detection phase wherein Arabic text was found and 127k Arabic character dataset for the recognition phase. The phase-1 labels were generated from an Arabic corpus of quotes and sentences, which consists of 15kquotes and sentences. This study ensures that Arabic Word Awareness Region Detection (AWARD) approach with high flexibility in identifying complex Arabic text scene images, such as texts that are arbitrarily oriented, curved, or deformed, is used to detect these texts. Our research after experimentations shows that the system has a 91.8% word segmentation accuracy and a 94.2% character recognition accuracy. We believe in the future that the researchers will excel in the field of image processing while treating text images to improve or reduce noise by processing scene images in any language by enhancing the functionality of VGG-16 based model using Neural Networks.
