  • Urban green space is one of most important aspects of urban infrastructure for improving the quality of life of city dwellers as it reduces the heat island effect and is used for recreation and relaxation. However, no systematic management of urban green space has been introduced in Korea as past practices focused on efficient development. A way to calculate the amount of green space needed to complement an urban area must be developed to preserve urban green space and to determine 'regulations determining the total amount of greenery'. In recent years, various studies have quantified urban green space and infrastructure using remotely sensed data. However, it is difficult to detect a myriad small green spaces in a city effectively when considering the spatial resolution of the data used in existing research. In this paper, we quantified small urban green spaces using CASI-1500 hyperspectral imagery. We calculated MCARI, a vegetation index for hyperspectral imagery, to evaluate the greenness of small green spaces. In addition, we applied image-classification methods, including the ISODATA algorithm and Spectral Angle Mapper, to detect small green spaces using supervised and unsupervised classifications. This could be used to categorize land-cover into four classes: unclassified, impervious, suspected green, and vegetation green.

  • The purpose of this study is to diagnose problems by analyzing the status of system and user in order to activate the Urban Planning Information System(UPIS). The UPIS has been distributed to all local governments through pilot and expansion projects since 2003 to utilize spatial information in urban planning and administration. The original purpose was to use GIS to support planning and to support scientific decision making, but now the main task is to designate and manage zoning districts related to land use. Therefore, the UPIS is responsible for the production (preparation procedure) and management of the local district information for use in the Korea land use information system, which is an upper concept defined by the law, but it is evaluated that its identity is ambiguous and utilization rate is low. This study is conducted to investigate the four aspects (business process, database, system, citizen service) of UPIS, and suggest concrete improvement measures. To summarize, each individual system exists in the Korea land use information system, but they all share similar data and have a linked work flow. Therefore, we suggested that the DB current plan should be established to improve the reliability of data and to redefine the business process around the UPIS.

  • With the global rise in interest in competency-based education, the Ministry of Education of the Republic of Korea outlined six core competencies in the 2015 revised curriculum, essential for future society's 'creative and convergent talent'. This study introduces an HTE-STEAM constellation education program designed to develop the core competencies outlined in the 2015 revised curriculum and address the limitations of hands-on astronomy education. The program's effectiveness was assessed through a pilot test. The program was implemented at G Library, an out-of-school education site in Cheongju-si, Chungcheongbuk-do, targeting students from 3rd to 6th grade. The study's results include: First, the HTE-STEAM program significantly impacted all aspects of the STEAM attitude test except for 'self-concept', particularly influencing 'science and engineering career choice', 'consideration', and 'communication'. Thus, it has led to positive outcomes in the cultivation of future society's core competencies, including 'creative thinking skills', 'communication skills', and 'community skills'. Secondly, the HTE-STEAM constellation education program, despite covering the challenging concept of spacetime, was deemed easy by many students. Observations of students applying the spatial concepts they learned by using teaching aids suggest that the program was effective in enhancing students' understanding of the spatial structure of the sky and the universe. Additionally, this program aligns with the 2022 curriculum's updated standards for understanding the sky's spatial structure. Consequently, the HTE-STEAM constellation education program positively cultivates future society's core competencies and serves as a valuable complement to night observation practices in schools.

  • The purpose of this study is to analyze the design characteristics of Hanok hotel. This study was approached by using theoretical investigation and a field survey. The field survey analyzed the current situations by conducting the master plan layout, architecture and interior design of the Hanok hotel. The field survey was tested by examining four different Hanok hotels from February 2014 to July 2014. After all, the results were analyzed based on given categories. The results of this research can be summarized as following. First, the characteristic of the master plan layout in Hanok hotel was appeared as "ㄷ" and "ㅡ" shapes. Those layouts were based on the spatial and the functional aspects of Hanok hotel facilities. Second, three different structural methods such as the korean traditional wooden structure, concrete, and masonry method were used in Hanok hotel construction to deliver the traditional architecture aspects while considering the functionality and convenience of the building. Third, most of Hanok hotels had the limited furniture range. The consideration of using several types of traditional furniture in different rates of the guest rooms help to increase the service quality and customer's satisfaction. Fourth, there were no diversity of using materials and colors in Hanok hotels that only few of them were used to express the traditional look. Fifth, the local characteristics were found in several Hanok hotels. To reflect the local characteristics in Hanok hotel is to construct a suitable environment to fit in nature and also it is easily to convey the local culture to others.

  • The purpose of this study is to investigate how the 6 entry plans of Seoul Park in Paris were representing the tradition by comparing and reviewing them. Entry plans proposed for Seoul Park revealed different approaches of representing traditional gardens. Through scrutinizing these plans, some similar and different aspects among them could be found out. In order to find out those aspects, the entry plans were analysed and compared into several categories such as design concepts, programs and spatial components. The main concern for analysing the entry plans focused on the issue of are presentation. Representing a Korean garden into Seoul Park depends on the manner of a representation, their objets and media. Objects are related to the contents. The contents can have various themes, events, places beyond the garedn. Meids is related to represent Korean tradition with what implement. The manner of a representation can be divided into three types; a direct representation, an abstract(metaphoric) representation and a destructive representation. We found the characteristics through analysing the entry plans that 1) Korean terrain, Korean thoughts, narrative promenade, past/present/Korea/Seoul, story telling through the Korea traditional fence were used as design concepts. 2) Traditional elements such as a traditional pavilion, fence, madang, hwagye, gate were generally chosen as essential elements for representing the Korean tradition. 3) Direct representations were ore broadly used than abstract and destructive representation as the manner of a representation. and 4) The entry plans show us a variety of possibilities of representing traditional gardens. Abstract and destructive representations of tradition can be found out in th several plans compared with other existing ocean gardens made in foreign countries. In establishing urban parks and ordinary landscapes, those strategies can be alternatives to represent the identity of Korea by reconciling tradition with invention.

  • Korean society has been recently promoting the restoration of coastal wetlands. These efforts might become the basis of a policy framework that compensates for the limitations of a regulation-oriented policy such as the designation of Marine Protected Areas (MPAs). The shift in government policy could contribute to strengthening the socioeconomic infrastructure of coastal development through the accumulation of ecological capital. Although our scientific efforts and social demands in regard to the ecological restoration of the coastal wetlands have increased during the past years, the bases for restoration in Korea requires that scientific, technological, financial, social and legal aspects be enhanced. The present study re-examined the concept and attitudes behind coastal wetland restoration in the light of changing circumstances in Korea. Herein, we first defined coastal wetland restoration as "An act of recovering the functions of the ecosystem of coastal wetlands to a state that resembles conditions prior to being damaged." Next, this study discussed the limitations and future directions of such restoration efforts based on the descriptive analyses of recent restoration practices from social, economic, and technological aspects. Finally, we suggest future policy directions regarding coastal wetland restoration on the basis of a PFST (Policy, Financial, Social, and Technological) analysis; 1) re-arranging legal mechanisms, 2) setting multi-dimensional restoration goals, 3) establishing a multi-discipline- and convergence based R&D system, 4) linking spatial management and local development to the restoration, 5) building restoration governance at the local level, 6) implementing an ecosystem service payment system, and 7) applying test-bed projects in accordance with proper directions.

  • Advancement toward aging society has presented the importance of house planning in consideration of the elderly, increasing the necessity of such planning. Therefore the importance of indoor design guideline for elderly houses has been stressed and the understanding of the aging in regard to this trend will create more mature spaces. In line with this trend the purpose of this study is to study the medical factors related with bathroom interior design guidelines of the existing elderly houses from the viewpoint of deteriorating physical functions due to aging process. In order to research the deterioration of physical functions due to aging literatures of medical and exercise physiology were used and concerning the existing bathroom design guidelines for the aged people, the guideline items of behavior facilitation, physiological maintenance and perceptual maintenance aspects out of Murtha & Lee's user benefit criteria(1976) related with physical functions were selected to research in relation with the knowledge about the deterioration phenomena of physical functions. Physical aging and deterioration aspects were classified from the viewpoint of musculoskeletal disorder, cardiovascular disorder, respiratory disorder, gastronomy disorder, urology disorder, somatosensory disorder, endocrine disorder, immune disorder, nervous disorder and skin diseases and these were utilized in interpreting total 100 items of bathroom design guideline. Because bathroom is the space where many physical movements are done, it had the closest relationship with the deterioration of musculoskeletal health in general and as bathroom is the space where people use water and feel the difference in temperature and moisture more than other spaces, deterioration of skin and somatosensory health had the next closest relationship. The result of this study revealed that regarding the deterioration of physical functions of the elderly people in aspect of their perceptibility as designers will design creatively and sincerely based on its relationship with nervous system in future, the result of this study will be used to develop better spatial designs efficiently to meet for the aging society.

  • The high oxidants, which occur the daily maximum concentrations in the afternoon, are transported into the other region via long range transport mechanisms or trapped within the shallow mixing boundary layer and then removed physically (deposition, transport by mountain wind, etc.) and chemically (reaction with local sources). Therefore, modeling formation of photochemical oxidants requires a complex description of both chemical and meteorological processes. In this study, as a part of air quality studies, we reviewed various aspects of photochemical modeling on the basis of currently available literature. The result of the review shows that the model is based on a set of coupled continuity equations describing advection, diffusion, transport, deposition, chemistry, emission. Also photochemical oxidant models require a large amount of input data concerned with all aspects of the ozone life cycle. First, emission inventories of hydrocarbon and nitrogen oxides, with appropriate spatial and temporal resolution. Second, chemical and photochemical data allowing the quantitative description of the formation of ozone and other photochemically-generated secondary pollutants. Third, dry deposition mechanisms particularly for ozone, PAN and hydrogen peroxide to account for their removal by absorption on the ground, crops, natural vegetation, man-made and water surfaces. Finally, meteorological data describing the transport of primary pollutants away from their sources and of secondary pollutants towards the sensitive receptors where environmental damage may occur. In order to improve our present study, shortcomings and limitation of existing models are pointed out and verification process through observation is emphasized.

  • The purpose of this study is to examine the trend of plural eclecticism in costumes appearing on the stages of the world's top 4 musicals based on the general researches and establishments made of the mentioned concept. The conclusions of this study are as follows. First, the aspects of eclectics appearing in overall pieces can be defined as situational eclecticism. It can be attributed to the dramatic elements contrasted in the storyline of the musical and occurs in mixture with various situations. Showing combinations of costumes from varying situations at once in the same stage makes the audience feel the dynamic elements of the piece. Second, the aspect of temporal eclecticism, which can be seen in the 'Phantom of the Opera' regarding mixture of crinoline style and art nouveau style, resulted from the partial mixture of classical elements for maximizing visual beauty in the historical pieces. Third, the aspect of spatial eclecticism can be observed in the musical 'Miss Saigon', which used costumes that combined multicultural elements by exposing different spaces and cultures such as America and Vietnam. It eclectically expresses the unique cultures and costumes of each country. Fourth, 'Les Miserables' shows the aspect of situational eclecticism, through its use of mixture of situations in various aspects, and in particular, the male and female costumes that blur the boundaries of life, death, and costume, the mixture of people's costume and aristocrat's costume, and the situational elements where the good and evil are contrasted are integrated eclectically to make the story dramatic.
