Due to sporadic development projects and Korea's geographical characteristics slopes are inevitable. Consequently, widespread slope greening projects are underway, prioritizing safety and landscape integration. Experimental research is being conducted on slope greening methods and their effects; however, there is a dearth of research on the various conditions resulting from slope greening construction defects. This study examined different conditions and assessed greening methods on real-world sites to understand their correlation with slope greening. Even in the same areas, the state of slope greening varied in different conditions. This underscores the importance of pre-evaluating specific conditions to achieve efficient slope greening results across various conditions. Consequently, there is a need for guidelines and institutional frameworks to assess various conditions in future endeavors.

Recently, landscaping construction has played a significant role in enhancing the quality of life for citizens by creating and maintaining outdoor spaces. However, landscaping projects vary in material procurement depending on the contracting method, and they also present various challenges in defect occurrence and defect rectification due to their specialized nature. In this study, we classified different types of projects based on material procurement ratios and conducted on-site assessments of defect status by specific processes. We also analyzed the itemization of material ratios and defect rectification costs. The results revealed it was found that projects with a higher proportion of government-provided materials had the poorest defect status in terms of planting works and also incurred the highest defect rectification costs. Moreover, conflicts concerning the responsibility for defects arose. Currently, there are no specific guidelines for setting standards for the proportion of government-provided materials in landscaping construction contracts. Furthermore, there is ambiguity in the management of defect rectification. Therefore, it is necessary to establish a systematic landscaping construction contracting framework by providing institutional guidelines tailored to local governments or the circumstances of contracting entities and to conduct thorough reviews of construction processes.

The major objective of this study was to develop recommendations for improving the design of pergola facilities located in neighborhood parks. The study employed the following methods : Physical measures and questionnaires. Physical treasures were taken of certain environmental attributes such as pergola sizes, structures, materials, etc. Questionnaires were randomly distributed to pergola users on the same day on which physical measures were scheduled. All data were collected in 1994 during the season of pergola use, September 3 to October 9. The major findings are as follows; 1. Of the 508 respondents to the question about use motivations, approximately 32% were a shady place, 18% seating arrangements suitable for conversation, 15% unconsciously, 13% a lack of bench in the park, 9% good view, and 13% other. 2. Regression analysis indicated that the best predictors of pergola user' satisfaction were : harmony with surroundings, accessibility, aesthetics of pergolas and benches, function of benches, and climbing plants. 3. Pergola design needs to be developed because pergola users were less satisfied with their pergola than with the park.

The purpose of this study is to search for the characteristics of the theory of 'placeness' permeated through contemporary museum architecture in Korea, and hereby to prove the possibility of coping with the modernity in Korean architecture. In this study the theory of 'placeness' which is asserted by Christian Norberg Schultz has been adopted in debating contemporary architecture in Korea. Therefor the theory of 'placeness' has been researched to get an angle of vision on the proof of coping with the modernity in Korean architecture. Seven contemporary museum architecture which have been completed since 1990 have been examined in the view of morphology, topology, and typology which are the major factors of 'placeness'. Throughout this case study, the post-modernity in museum architecture in Korea has been proved, which establishes that the 'placeness' is one of the alternatives for contemporary architecture in Korea.
