3D modeling and rendering technologies are getting more attention from landscape planners and architects because the virtual reality based on 3D graphic technology could give more realistic experience to landscape simulation users and boost promotional effects. The 3D landscape simulation, however, not only requires a lot of cost and time in production, but also demands efforts to distribute to consumers due to various computing environment of them. The purpose of this study is to suggest a process for developing an interactive 3D landscape simulator with low-cost, which can support multi-platform functionality in high quality through reviewing related current software and web services. We select GIMP for 2D image texturing, SketchUpfor 3D modeling, Unity for real-time rendering, and Google Earth for terrain modeling considering price and workability and apply the developed process for Windows, Web, and Android versions to test the applicability for Sangji-ri, Gosam-myeon, Gyeonggi-do, Korea.

Integrated CI (country identity, community identity) planning is necessary for establishing identity and a distinct image as well as for managing green tourism villages. In addition, CI planning will be helpful for improving and advertising a village's image, capitalizing on its specialties and attracting many visitors to the village. Therefore, this study mainly intended to plan and design integrated CI for a green tourism village. For this purpose, this study selected Hari village in Hongsung-Kun, Chungnam province, which the Ministry of Agriculture and Forestry designated as a green tourism village in 2003. Twenty CI alternatives were developed, and a vote was conducted with 143 visitors and rural residents attending a village festival in 2004. This study resulted in a new brand-name, 'Hanuri,' and developed symbols, logotypes, distinctive colors, signature system as a basic system and name cards, packaging materials, and signs for use. Above all, this study led the residents to pursue a village identity, village image and community spirit, which can be an effective management strategy to create a distinct image in a green tourism village.

In today's highly digitized landscape, securing digital communication is paramount due to threats like hacking, unauthorized data access, and network policy violations. The response to these challenges has been the development of cryptography applications, though many existing techniques face issues of complexity, efficiency, and limitations. Notably, sophisticated intruders can easily discern encrypted data during transmission, casting doubt on overall security. In contrast to encryption, steganography offers the unique advantage of concealing data without easy detection, although it, too, grapples with challenges. The primary hurdles in image steganography revolve around the quality and payload capacity of the cover image, which are persistently compromised. This article introduces a pioneering approach that integrates image steganography and encryption, presenting the BitPatternStego method. This novel technique addresses prevalent issues in image steganography, such as stego-image quality and payload, by concealing secret data within image pixels with identical bit patterns as their characters. Consequently, concerns regarding the quality and payload capacity of steganographic images become obsolete. Moreover, the BitPatternStego method boasts the capability to generate millions of keys for the same secret message, offering a robust and versatile solution to the evolving landscape of digital security challenges.

Biophilic design gives human beings positive and valuable experiences in nature. The experience in nature in the architectural environment is mainly symbolic and metaphorical, and is based on visual sensations such as color, form, and image. Recently, modern people living in a modern and simple style indoor space have a desire to pursue visual stimuli for interest or pleasure. This desire can be satisfied through color, lighting, and finishing plan. Therefore, the purpose of this study is to propose a biophilic design color palette based on the empirical characteristics and properties of biophilic design. The methods used in this study are as follows. First, the biophilic design factors and natural landscape preference criteria are examined. Second, based on the review results, natural landscape images are selected and color information for each biophilic design element is extracted according to the vertical and horizontal directions. Third, color information is converted to NCS color code and palette range and hue range are derived through the analysis of ratio and average values. Finally, based on the analysis results, biophilic design color palette is proposed for each element. The results of this study might be useful as basic data in establishing biophilic design strategies and applying them to architecture and interior construction.

자연속에서 새로운 것을 추구하고자 하는 사람들의 의식 변화로 길은 기능 중심의 '걷는 길'에서 목적 중심의 '걷고 싶은 길'로 변화하고 있다. 지금까지 조성되고 있는 '걷고 싶은 길'은 길을 따라 걷는 과정에서 보고, 느끼고, 체험하는 다양한 목적을 가진 긴 선적 공간이라 할 수 있지만, 노선 선정 시 길을 걷는 과정에서 보여지는 길의 경관에 대한 고려는 미흡하다고 할 수 있다. 길을 걸으면서 느끼고 지각하는 경관은 '걷고 싶은 길'을 이용하는 이용자에게 하나의 목적을 제공할 뿐 아니라, 길 이용에 대한 만족도를 향상시킬 수 있는 중요한 요소라 할 수 있지만, 걷고 싶은 길의 경관적 측면에 대한 연구는 미흡하다고 할 수 있다. 따라서, 본 연구는 북한산 둘레길을 대상으로 하여 경관적 측면에서 시각적으로 지각되는 길 경관에 대한 이미지 및 선호도를 분석하고, 이용 만족도와의 상관성을 분석함으로써 걷고 싶은 길 노선 선정 과정에서 경관적 측면을 고려하여 이용자 만족도를 향상시킬 수 있는 방안을 모색하고자 하였다. 이를 위하여 북한산 둘레길 13개 구간에 대하여 구간별 대표경관 사진을 선정하고, 경관평가를 위한 경관이미지 형용사를 선정하여 경관평가를 시행하였다. 경관평가를 통해 구간별 경관이미지, 걷고 싶음 및 경관선호에 영향을 미치는 경관이미지 요인, 경관선호와 이용만족도와의 관련성을 알아보았다. 경관이미지는 수목이 많고 인공적 요소의 지각이 덜한 길에서 '상쾌한' 이미지가 높게 나타나고, 인공적 요소의 지각이 높은 길에서 '도시적인' 이미지가 높게 나타났다. '걷고 싶음'과 '경관미 선호도'는 자연적 요소가 높아 '상쾌한', '전원적인' 이미지가 높은 길에서 높게 나타났다. '걷고 싶음'에 영향을 미치는 요인으로 "상쾌한-불쾌한", "인상적인-평범한" 이미지로 나타났으며, '경관미 선호도'에 영향을 미치는 요인으로 "상쾌한-불쾌한", "편안한-불편한" 이미지로 나타났다. 또한, 경관선호도는 이용 만족도와 높은 상관관계가 있는 것으로 나타났다.

Urban sprawl has been the limits of traffic accommodate and the supply road. Thus, Light Rail Transit(LRT) has been proposed as the best alternative. Owing to landscape damage from construction of LRT, landscape planning should be considered seriously in the urban planning step. This paper therefore seeks to determine landscape improvement direction of LRT pier. First, the methods in this study shared landscape improvement direction type of LRT pier through previous studies such as planting of surface(30%, 60%, 90% planting of surface), graphic(character, commercial advertising, symbol), and surface treatment type(exposed concrete, white painting, pattern dies). Next, respondent evaluated 3D simulated landscape image accordingly shared types by preference and landscape adjectives using in streetscape evaluation. As a result, visual preference was the highest in planting type of surface and the lowest in the surface treatment type. Covering 60%(4.48) in planting type of surface was the highest. Because it is similar to the golden ratio considering the visual principle, we will need to take advantage through the result of this paper. Also, most landscape improvement direction which satisfied with significant level showed a positive effect from landscape improvement. Comprehensively based on these results, it suggests desirable landscape improvement direction of LRT pier in the city for solution of landscape inhibition problem.

Aerial videography techniques have been used to inventory conditions associated with grassland, forests, and agricultural crop production. Most recently, aerial videography has been used to verity satellite image classifications as part of the natural ecosystem survey. The objectives of this study were: (1) to use aerial video images of the study area, one part of Taean Seashore National Park, for the accuracy assessment, and (2) to determine the suitability of aerial videography as an accuracy assessment, of the land cover classification with Landsat-TM data. Video images were collected twice, summer and winter seasons, and divided into two kinds of images, wide angle and narrow angle images. Accuracy assessment methods include the calculation of the error matrix, the overall accuracy and kappa coefficient of agreement. This study indicates that aerial videography is an effective tool for accuracy assessment of the satellite image classifications of which features are relatively large and continuous. And it would be possible to overcome the limits of the present natural ecosystem survey method.
