After UNESCO appointed Royal Tombs of the Joseon Dynasty to be World Cultural Heritages(2009), Cultural Heritage Administration in Korea established Management Office of Royal Tombs of the Joseon Dynasty(2012) and conducted Mid to Long-Term Plan on Conservation, Management, Utilization of World Heritage 'Royal Tombs of the Joseon Dynasty(2015)'. The report, as an implementation plan, provides detailed contents of the maintenance planning of Royal Tombs of the Joseon Dynasty. From this background, with a view to comprehending the characteristics of the maintenance planning of trees in historical landscape forests, this study extracted the contents related to the historical landscape forests of the 40 Royal Tombs of the Joseon Dynasty from the "Mid to Long-term Plan" and conducted literature research. The results of the study are as follows. First, from 2016, the short-term plans have provided detailed contents on logging, transplanting and planting trees in the plans divided by stages. On the other hand, the long-term plans, instead of presenting abstract contents repeatedly for each royal tomb, should seek vegetation landscape that each royal tomb should aim for. Second, since the areas that are in charge of the various functions of the royal tombs have been subjects to the maintenance planning, it is effective to establish a maintenance planning by separating functional areas instead of the comprehensive concept as historical landscape forests. Third, the maintenance planning of trees in historical landscape forest of the Royal Tombs of Joseon Dynasty is based on daily management such as density control and maintaining the shape of trees, which is necessary to sustain the forest. Also, due to the goal of preserving the pine forest, which is recognized as a prototype vegetation landscape, foreign species and other trees have been more cut down. With a few limited types of tall tree but few shrubs and flowers, it is characterized that the orientation toward aesthetic landscapes is insufficient in large green spaces. Fourth, according to the function of the tomb, it is divided into entrance area, ceremonial area, burial area and outer forest, and the contents of the maintenance planning are analyzed by basic conditions of tree management: prototype, ecology, functionality, and aesthetics. After studying the tree management characteristics of each area, four suggestions are made: understanding the diversity of trees that form prototype landscape as a management plan, sustainability of various forests adapted to ecological environment, convenience required in addition to ceremony and safety characterizing the Royal Tombs of Joseon Dynasty, and the necessity of access to aesthetic landscape on the tombs.

This study is aimed at suggesting a plan for creating a landscape environment by grasping a landscape preference according to the change of middle span and sag ratio which is a consideration factor when designing the suspension bridge representing long-span bridges and image property of the bridge while applying SD method to a relation between landscape preference and image factor, and a connection of design element with image factor. An analysis on landscape preference about the bridge landscape showed from what the longer the length of middle span, the extent of sag ratio of preference decreased, the longer the middle span low sag ratio was preferred and the higher the landscape preference became. In landscape preference and image factor, the attribute of sag ratio with high landscape preference was all positively correlated with "stability", "plasticity", and "aesthetic" but an influence of "plasticity" was insignificant. In the relation between design element and image factor, the factor of middle span and sag ratio was more related to the factor of "stability" and the lower the sag ratio and the longer the middle span, the higher the "stability" was rated. This result showed the image property of "plasticity" was insignificant among the one of preference in landscape and to highlight the one of "plasticity" a complementary experiment was done with a change in balance and symmetry elements not in proportional element of middle span and sag ratio. The result showed the image property of "plasticity" was more highlighted in the suspension bridge of 3-tower and different bilateral symmetry at sag, and when designing the landscape of suspension bridge later on, the elements of balance and symmetry as well as the proportional element should be considered and reflected in the design.

야간 조명은 건강과 복지에 대한 인간의 욕구를 야간시간의 활용을 통하여 충족시킬 수 있도록 도와주고 있다. 또한 조명은 경관의 활성화와 미적 공간 창출의 유용한 도구로 이용되고 있어 근린공원에서의 조명은 주간과 다른 분위기를 제공하여 이용자들의 만족도를 높여주고 있다. 하지만 위험 요인을 가지고 있는 공원에서는 심미적 효과뿐만 아니라 이용자들의 보행 안전을 위한 야간 조명설계의 중요성이 강조된다. 본 연구는 야간 근린공원 이용자들의 보행 안전을 고려한 조명설계를 위하여 시뮬레이션 접근법을 이용하여 대안 조명품질을 비교한다. 기존에 설치된 조명기구와 타 조명기구를 시뮬레이션으로 비교함으로써 조명설계시 시뮬레이션 접근법의 유용성을 제안한다.

This study has evaluated the visual preference factor of Keum river sceneries which could vary according to the change of water level while other scenic environment near by the river did not change. 1) At Gap Cheon site, the variances of the visual preferences for river scenery at different water level are determined as emotional, physical, aesthetic and individual factor. At Mujoo site, the variances of the visual preferences are determined as only two factors such as emotional and physical factors. Those factors show significant relations. All of the visual preferences are increased as the increase of preference factors. Also decreasing of preference factors result in decreasing of visual preferences. 2) In multiple regression model, both the Gap cheon site and Mujoo site show that the increase of emotional factor affect most to visual preference when other conditions are fixed. The physical factor affect less than the emotional factor. At Gap cheon site, the relative importance level which the preference factors contribute to the visual preference appears as the order of emotional, physical, aesthetic and individual factor. Emotional factor's importance level is 4.2 times greater than individual factor. At Mujoo site, the relative importance level which the preference factors contribute to the visual preference appears as the order of emotional and physical factor. The emotional factor's importance level is 1.1 times greater than physical factor. It is clearly indicate that the emotional factor is most important preference factor in both study sites. The factor analysis results of Keum river scenery at different water level using the visual evaluation method affect a lot to the quantification of river instream flow and water level.

As environmental problems accompanied by industrialization have emerged worldwide, solar and wind energy have entered the stage of commercialization, especially in Korea. In addition, research on improving aesthetics using solar cells is being actively conducted. Examples include developing a transmissive solar cell and developing a solar cell with flexibility and color. Therefore, in line with the upward trend of solar cell development and solar cell-based public facility installation, we will present guidelines for designing public facilities using solar cells to improve aesthetics. First of all, components were derived to increase the suitability of solar cell application through literature surveys on solar cells and case studies on public facilities using solar cells. Next, through prior research on public facility guidelines, we established evaluation principles and drafted design guidelines. Based on this, a Delphi survey was conducted on a group of experts to verify its validity. Design guidelines for solar cells application measures to improve the final public design aesthetics were derived. The goal is to improve the public facilities using solar cells, through Accessibility and cognition, Usability, Shape and aesthetics, Sustainability and energy efficiency, Continuity with the urban landscape. And it is expected that this data will be used to improve the aesthetics of public design using solar cells in the future.

This study began with the question: "what influence would the width of river surface have on visual preference, provided that the environment surrounding the river does not change?" to evaluate the visual preference factors of the river scenery which could vary according to the change of water level. To estimate the minimum flow needed for river sceneries, field survey of Youngsan river was carried out to collect the field data and evaluated the visual preference factors to obtain a most preferred W/B ratio. At Youngsan bridge location, the feeling of open space factors, physical characteristic factors and complexity factors appeared to have significant relations to visual preferences. At Imgok bridge location, complexity factors, aesthetic factors and physical characteristic factors have significance to visual preferences. As a result of multi regression modeling, it was found that physical factors affected visual preferences the most at urban river locations and complexity factors affected the most visual preferences at rural river locations. As a results of this study, the most preferred W/B ratio was estimated as which vary from 0.5 to 0.7 and this results can contribute to the field of river landscape design to maximize the users' satisfaction level.

Recently, the conservation of mountainous landscape and compensation for diverse demands for mountain areas such as leisure, recreation and welfare are under discussion. The purpose of this study is to investigation the perception of mountainous landscapes by those who view and recognize the landscapes and to estimate economic value by estimating the willingness to pay for the management of mountainous landscapes. This study will provide data for the management of mountainous landscapes. As a result of comparing the perception between the territorial landscape and the mountain landscape, the mountain scenery was 3.96, the management level satisfaction was 3.28, and the management necessity was 4.38, which was higher than the national landscape, while the national landscape was satisfactory but the management level was insufficient. Jeju Island (39.0%) and Gangwon (38.6%) were chosen as the most scenic areas with beautiful forest and mountainous landscape resources. The aesthetic characteristics of the vast skyline of mountain scenery, the background of the area, and the mountainous landscape that forms the landmark were evaluated highly. And, it is considered that consciousness of mountainous landscape management is heightened by 86.8% of respondents, who positively answered the Mountainous Landscape Visual Impact Assessment before the development project. The per capita payment amount for mountainous landscape management was calculated to be 3,742 won and, based on the number of visitors to the mountain National Parks in 2016, it is estimated to have an economic value of about 169.5 billion won. Policymakers have limitations in the mountainous landscape management policies of the administrative subject. Establishing a consensus on the importance and necessity of landscape management by diagnosing the status of public perception is expected to help create more effective policy direction and implement strategies for the management of these areas.

It is an attempt to suggest the standard valuation method of the environmental illumination for the bridges across the Han-river from an aesthetic point of view, deviating from the technical and traditional viewpoint. In Korea the current evaluation criterion to verify the value of bridge design has a partiality for the technical and structural safety rather than the sentient beauty on the whole. However, the recently cultural reform of Korean mass society with the elevation of the standard of living forces the engineering designers for bridges to focus not only on competing physical structures but also on enhancing the formative beauty including the illumination effects for night view. Additionally, the new policy, which transforms the environments around the Han-river into the major tourist attractions has been executing strongly by the city authorities to revitalize the symbolic, historic, and cultural identity of the capital city with the introduction of the high-quality environmental illumination for the bridges. As a result, It becomes necessary to establish the manual and standardization of the environmental illumination planning for the city in terms of the formative beauty, and this study is to suggest the valuation model method of the environmental illumination for the bridges as the initial step of the standardization. In the study, the valuation items of the standard questionnaire are selected by the documentary records and the consultation of various experts in architecture, design, fine art, urban planning and even administration to verify the essential elements of the aesthetic beauty with the local amenity and the environmental harmony for the chosen bridges across the Han-river.
