The purpose of this study is to examine and understand the area and the original outer boundaries of Hamchunwon(含春苑), which was the outer royal garden of Gyeonghuigung Palace, which existed before the site of the Russian legation. The results of the study are as follows. First, examining the 3 types of drawings prepared for securing the Russian legation's site and constructing a new building, it was confirmed that two low peaks, which appear to be the original terrain of Hamchunwon, existed in the north and south directions inside the site. According to the initial plan of the of the legation's site, it appears that the entrance of the legation building is connected to the Saemunan-ro in the northwest. However, according to the report made at the time when the Russian temporary minister Veber purchased the legation's site, it was recorded that the site already had a narrow entrance and a dirt road in place, and hence, it was connected to Saemunan-ro. This fact makes it possible to learn that the line of movement for officials and the original gate were located to the northwest of the site planned as the entrance of the legation building towards Hamchunwon. Second, the site was created by cutting the top of the high hill at the time of the construction of the legation building, and as a result, a two tiered staircase typed terrace was built. The ground on which the main building and the secretary's building, etc., were erected was made by cutting the highest peak and solidifying it flat, and a large quantity of soil was used for grading. In the case of the northern area of the main building, the traces of leveling the terrain by cutting the mountains are apparent, and an observation typed garden with a walking path and pavilion was formed by utilizing the physical environment equipped with an easy view. This may be considered as a use which is consistent with the topographical conditions of creating an outer royal garden to block the civilian views on a high terrain overlooking the palace. Third, Hamchunwon's fences were partially exposed in the photos from the 1880s through the 1890s, which demonstrate the spatial changes made around the US, UK, and the Russian legations. As a result of the photo analysis performed, Hamchunwon occupies the northern area of the Russian legation's site, and it is estimated that the north, west, and east walls of the legation resembled those of Hamchunwon. The area to the south of the Russian legation was originally a place made available for civilian houses, and it was possible to examine the circumstances of purchasing dozens of civilian houses and farmlands according to various materials. Fourth, Hamchunwon, which was formed as the outer royal garden of Gyeongdeokgung Palace of Lord Gwanghaegun, lost its sense of place as an outer royal garden when the entire building of Gyeonghuigung Palace was torn down and used as a construction members during the reconstruction of Gyeongbokgung Palace, and faded away as the site was sold to Russia around 1885. The area where Hamchunwon used to be located transformed into a core space of the Russian legation where the main building and garden were located after the construction of the new building. Hence, Hamchunwon, which was limited to the northern area of the Russian legation, does not carry the temporal and spatial context with Gyeongungung Palace and Seonwonjeon which were constructed after 1897, and it is determined that the view of Seonwonjeon as Baehoorim or Baegyeongrim is not valid.

As the need of indoor spatial information has grown, many applications have been developed. Nevertheless, the major representations of indoor spatial information are on the 2D or 3D, recently, the service based on omni-directional image has increased. Current service based on omni-directional image is used just for viewer. To provide various applications which can serve the identifying the attribute of indoor space, query based services and so on, topological data which can define the spatial relationships between spaces is required. For developing diverse applications based on omni-directional image, this study proposes the method to generate IndoorGML data which is the international standard of indoor topological data model. The proposed method is consist of 3 step to generate IndoorGML data; 1) Analysis the core elements to adopt IndoorGML concept to image, 2) Propose the method to identify the element of ‘Space’ which is the core element of IndoorGML concept, 3) Define the connectivity of indoor spaces. The proposed method is implemented at the 6-floor of 21centurybuilding of the University of Seoul to generate IndoorGML data and the demo service is implemented based on the generated data. This study has the significance to propose a method to generate the indoor topological data for the indoor spatial information services based on the IndoorGML.

A passive type of fence security system was developed, which was based on electric charge detection technique. The implemented fence security system was installed at outskirts of greenhouse laboratory in the University of Seoul. The purpose of this research is to minimize false alarms by analyzing environmental noise. The existing system determines the intrusion alarm by analyzing the power of amplified signal, but the alarm was seriously affected by natural strong wind and heavy rainfall. The SAU(Signal Analysis Unit) sends input signals to remote server which displays intrusion alarm and stores all the information in database. The environmental noise such as temperature, humidity and wind speed was separately gathered to analyze a correlation with input signal. The input signal was analyzed for frequency characteristic using FFT(Fast Fourier Transform) and the algorithm that differentiate between intrusion alarm and environmental noise signal is improved. The proposed algorithm is applied for the site for one month as the same as the existing algorithm and the false alarm data was gathered and analyzed. The false alarm number was decreased by 98% after new algorithm was applied to the fence. The proposed algorithm improved the reliability at the field regarding environmental noise signal.

This experiment was conducted to acquire the basic data necessary for the artificial pond greening. Eighty four hydrophytes collected from 11 domestic small ponds and a farm were used in this experiment. The size of the artificial pond used was $6m{\times}3m{\times}1.5m(length{\times}width{\times}depth)$. Twelve months after planting, species were selected for their high ornamental values and tissue contents of N and P in each month. Tissue contents of N in Trapha nantan, Nymphoides indica, Nymphaea hybrid, and Murdannia keisak were high. Tissue contents of P in Monochoria vaginalis and Murdannia keisak were also high. The pH of artificial pond stabilized at a 6.8~7.6 range from May 2005 to March 2007. The EC was low in summer and high in autumn. From April to October, 5, 19, 23, 32, 31, 28, and 26 species, respectively, were selected for artificial pond greening. One year after planting, vegetation changed from 78 species (Potamogeton octqandrus, Salvinia natans, Potamogeton malaianus, etc.) to 38 species (Scirpus tarbernaemontani, Scirpus karuizawensis, Scirpus triqueter, etc.). Species diversity in the artificial pond was as follows, indicating it being a stabilized artificial pond; 38 species, 1,437 total number of plants, species richness index of 11.72, and maximum diversity index of 0.97.

Extracting ground points is the kernel of DTM generation being considered as one of the most popular LIDAR applications. The previous extraction approaches can be mostly characterized as a point based approach, which sequentially examines every individual point to determine whether it is measured from ground surfaces. The number of examinations to be performed is then equivalent to the number of points. Particularly in a large set, the heavy computational requirement associated with the examinations is obviously an obstacle to employing more sophisticated criteria for the examination. To reduce the number of entities to be examined and produce more robust results, we developed an approach based on features rather than points, where a feature indicates an entity constructed by grouping some points. In the proposed approach, we first generate a set of features by organizing points into surface patches and grouping the patches into surface clusters. Among these features, we then attempt to identify the ground features with the criteria based on the attributes of the features. The points grouped into these identified features are labeled ground points, being used for DTM generation afterward. The Proposed approach was applied to many real airborne LIDAR data sets. The analysis on the results strongly supports the prominent performance of the proposed approach in terms of not only the computational requirement but also the quality of the DTM.

This thesis explores how JobGeuk ShimChungWangWhoJeon and the Devoted daughter ShimChungJeon scenario have transformed ShimChungJeon, a notable work of Pansori literature, dramatically for modern times. By analyzing the adapter's consciousness and changing direction in these two works, it was found that ShimChungJeon was tailored to audiences in the 1900s. JobGeuk and the scenario are attempts to transform ShimChungJeon to meet cultural needs in the 21st century and to make the works appealing to the public. The aspects of the transformation of JobGeuk ShimChungWangWhoJeon are 1) reinforcement of logical causality, 2) weakening the humor and simultaneously emphasizing the work's surreal nature, and 3) dramatic expression by song. The aspects of the change in direction of the Devoted daughter ShimChungJeon scenario are 1)the insertion of a new narrative, 2)trying to evoke both humor and tragic sadness, 3)seeking newness with the reassignment of time and events. JobGeuk ShimChungWangWhoJeon is the first example of the transformation of ShimChungJeon's dramatic style and Devoted daughter ShimChungJeon is the first transformation of its scenario. These two works show how ShimChungJeon can be adapted to modern times and new cultures, and how ShimChungJeon can be made relevant and be enjoyed by the public regardless of the era.

In 97hu2200, the Supreme Court of Korea suggested five requirements to apply the doctrine of equivalents, i.e. identity of problem-solving principles, interchangeability, ease of interchangeability, exception of known arts and file-wrapper estoppel. There have been arguments on whether the standard of ease of interchangeability could be regarded as the same as the obviousness standard in deciding patentability. The side who thinks that they are different (hereinafter, the side of difference) considers that the standard of ease of interchangeability is narrower than the obviousness standard. This side criticizes the side who thinks that they are the same each other (hereinafter, the side of the same) on the reason that doctrine of equivalents can be overly expanded. On the other hand, 'the side of the same' argues that every accused invention having no inventive step from the perspective of the patented invention should be considered to infringe. 'The side of the same' points that if the standard of ease of interchangeability is considered as narrower than the obviousness standard, 'grey area' should exist where the patent law cannot work. The difference between the two side may cause contradictory results in the decision of infringement under the doctrine of equivalents. Because 'the side of difference' construes claims narrowly than 'the side of the same,' an accused invention in the grey area is not regarded to infringe. 'The side of the same,' however, considers the accused invention to fall into the scope of the patent under the doctrine of equivalents. This paper concludes that the standard of ease of interchangeability should be regarded as the same as the obviousness standard from the perspective of economics of innovation.

The purpose of this research is to analyze the influence and legacy of Le Corbusier, who has been neglected in the past discourse of landscape architecture, on the formation of modernism in landscape architecture. The research examined the relationship between Le Corbusier's ideas and practices and modern landscape architecture in three parts. The first part analyzed chronologically the relationship between architecture and landscape in Le Corbusier's theories and practices. The evaluations and criticisms of Le Corbusier's landscape practices were also examined. The second part analyzed the relationship between Le Corbusier and European Modernism in landscape architecture and his influence on European modern landscape architects focusing on Vera, Lurcat, and Canneel-Claes. The third part looked into Le Corbusier's influence on American and British modern landscape architects including Tunnard, Chruch, Rose, Eckbo, and Kiley. The result of the research showed Le Corbusier's works and theories heavily influenced important landscape architects in Europe and America, who played key roles in forming Modernism in landscape architecture. Rather than introducing Le Corbusier's Modernism theory into the discourse of landscape architecture without questioning, modern landscape architects accepted his theory and practice of Modernism selectively with praise as well as criticism. Canneel-Claes, Turnnad, and Eckbo were the pioneers who tried to establish the basis of Modernism in landscape architecture by positively accepting Le Corubiser's thoughts on Modernism; whereas, Steel and Rose criticized Le Corubiser's attitude on landscape architecture. Church and Kiely were indirectly influenced by Le Corbusier in forming their Modernism style.

This study was conducted to see the differences of park users by classifying them with their park use frequency in terms of park use, management policy and perception, using the same survey results conducted in 2014 and 2020. Research was conducted on urban parks in Yangju, South Korea, and 740 in 2014 and 431 in 2000 survey results were used. After classifying the high-use and low-use groups according to park use frequency, this study compared the demographic differences and park use method differences according to the group, the recognition differences for the future park management direction between the two groups were analyzed and compared using statistical analysis by year. The results showed that the park's quantitative expansion and accessibility improvements were the most important issues in 2014, while the importance of park management, such as checking and improving aging facilities, providing various programs, and creating a themed neighborhood park that could reveal the identity of the area, was increased in 2020. Despite recognizing the importance of persistent management in the case of high-use groups, the results showed that they were less willing to participate in park management programs compared to less-use groups, which showed the need for a discussion of how to involve high-use groups for long term park management. This study contribute the body of literature that it seeks to understand differences of park user in terms of their park use frequency. However, in future studies, analyzing the differences of park users through a short-term study is required.

Digitalization of public administration information shall be accelerated more. When information exists both in the form of electronic and paper record, even the disclosure of paper record make it possible the access to public administration information itself, but there may some needs for the disclosure of electronic record in applicant's situation. Similarly, when only electronic record exists, there may be some problem about whether to disclose the record as print-out or as being electronic format itself. Thus, the method and format of disclose are very sensitive issues, and it is very important to clarify who has the competence to decide the method and format of disclosure, applicant or the public agency. In making any record available to an applicant under the EFOIA in America, the public agency shall provide the record in any form or format requested by the applicant, if the record is readily reproducible by the agency in that form or format. And for the convenience of the applicant with sensory disability, the AIA in Canada also permits the right to access to information in an alternative format. It is desirable also in our country that disclosure of information is done by public agencies in the format that applicant wants, as possible. In the meantime, we should consider the costs and technological restrictions corresponding to the change of format of information to the format that applicant specifies. In the case of electronic record, efforts required for searching cause some hard problems. Information disclosure system requires disclosure of record that exists at the demand point, and creation of new record that does not exist at that them is not required on the public agency. For the search of electronic information, we need some code or program. So, if we evaluate that act of coding or programming as creation of new record, demand on disclosure of electronic record becomes impossible, in fact. Therefore, when we include electronic record as the object of information disclosure system, we need to clarify the degree of reasonable efforts for searching the information included in that record, as long as possible, although it is very difficult problem. Also, we should consider the way to make it permitted to demand the disclosure of electronic record by FAX or E-mail. Disclosure of electronic record itself by E-mail is not generalized yet, even in America or Canada. There are many technological and legal problems to solve, before permitting or enforcing the disclosure of electronic record by E-mail. But, it is desirable to expand the method of disclosure to including disclosure by E-mail in possible spheres. Also, as well as disclosure on demands, we need to expand electronic access to information, so far as possible, in the process of information offer.
