With the advent of the Fourth Industrial Revolution, the amount of energy used in buildings has been increasing due to changes in the energy use structure caused by the massive spread of information-oriented equipment, climate change and greenhouse gas emissions. For the efficient use of energy, it is necessary to have a plan that can predict and reduce the amount of energy use according to the type of energy source and the use of buildings. To address such issues, this study presents a model embedded in a digital twin that predicts energy use in buildings. The digital twin is a system that can support a solution of urban problems through the process of simulations and analyses based on the data collected via sensors in real-time. To develop the energy use prediction model, energy-related data such as actual room use, power use and gas use were collected. Factors that significantly affect energy use were identified through a correlation analysis and multiple regression analysis based on the collected data. The proof-of-concept prototype was developed with an exhibition facility for performance evaluation and validation. The test results confirm that the error rate of the energy consumption prediction model decreases, and the prediction performance improves as the data is accumulated by comparing the error rates of the model. The energy use prediction model thus predicts future energy use and supports formulating a systematic energy management plan in consideration of characteristics of building spaces such as the purpose and the occupancy time of each room. It is suggested to collect and analyze data from other facilities in the future to develop a general-purpose energy use prediction model.

The purpose of this study is to explore the issues and implications for landscape design education in Korean landscape architecture by analyzing the National Exhibition of Korean Landscape Architecture(NEKLA). This study analyzed the suggested topics and selected site as well as the commentary that appeared in the NEKLA's award-winning book published from 2004 to 2014. Results of the study are as follows: First, topics of NEKLA are not only competition guidelines but related to exploring new area and role of Korean landscape architecture. Second, most dealing with site is 'industrial heritage and regeneration space' and 'green infrastructure'. In more recent years, a larger variety of sites were addressed. Third, site locations are concentrated in metropolitan areas, and awards and participation of the non-metropolitan universities was very low. Fourth, seven criteria can be applied in a general landscape design competition such as 'newness of the concept(idea)', 'logicality of the design process', 'selection of site fidelity of analysis(interpretation)', 'presentation and completion of the master plan', 'consistency with the theme', 'linkage of concepts and results' and 'feasibility'. The evaluation criteria are increasing the sophistication of the design language to provide useful suggestions on how to find design education methods. Its implications are as follows: First, training is essential to derive innovative ideas, but it should avoid excessive concept-oriented education. Second, design education may include instruction on how to define the problems related with the site. Third, more emphasis on design logic is essential to transform the innovative concept to actual results. Fourth, 'slick images' unrelated to design should be suppressed. Fifth, practice is needed to solve the topics addressed in the design process of education. Sixth, 'feasibility' and 'creative thinking' are necessary to recognize a reciprocal relationship that is helpful to one another. This study uses direct quote commentary to minimize the subjectivity of the researcher and to trace issues of the contemporary landscape architecture more directly and vividly. This study is a record waiting for another review as meta-criticism. In this regard this study, the landscape architect of the next times will have a mean that historical records to review the current thinking of the landscape theory and design.

This study was conducted to suggest alternatives for the effective use of national park visitor centers, by evaluating their functionality. Visitor centers in Naejangsan National Park and Pukhansan National Park, which are deliberately composed and managed, were investigated for this purpose. First, I clarified the concept, function and type of a visitor center through literature review, and then, analyzed visitors' post-visiting evaluation based on McManus's Communication Theory. The results of the analysis shows that visitors have not enough time to understand the contents of visitor centers, and facilities and guide sign system to support visitors are insufficient, which seem to disturb the proper communication between visitors and exhibits. Visitors' short visiting time caused by their little interest in exhibits and their low degree of understanding show the difficulties in the communication between visitors and exhibits. The following alternatives are suggested to improve these problems: first, the improvement of the guide sign system; second, the provision of exhibition rooms specialized for different visitor groups; third, the display of exhibits connected with visitors' experiences; Forth, the utilization of various media proper for each subject.

The purpose of this study is to investigate how much the programs of astronomy museums reflect the contents and objectives of current science curriculums. To attain the aim, comparison and analysis on the museum programs and science curriclum have been made. Five domestic astronomy museums have been selected. The contents and forms of their programs have been studied and appreciated by assessment instruments for astronomy museum programs. The assessment instruments were devised in consideration of both the science curriculums of the Ministry of Education(1997) and the achievement and evaluation criteria of the Korea Institute of Curriculum and Evaluation. The findings of this study are summarized as follows: The astronomy museums reflect most of the learning elements of science curricula concerning astronomy. These results indicate that the astronomy museum as an informal education institute is comparatively well connected to science education. The 5thgrade science curriculum reflected mostly on the museum programs, and too many of the astronomy museum programs were in forms of panel exhibition. Science curricula fared well but they failed to reflect the curricular objectives, which resulted in relatively low assessment scores. It is suggested that the findings of this study can be a foundation and act as guidance for selecting and developing astronomy museum programs which include the contents of the science curriculums more substantially.

Busan Biennale, began from 2000, has been argued that it would improve 'intrinsic introspection related to localism' against 'a lifestyle forced by capitalism in a global dimension', by promoting urban esthetic imagination in the public sphere of the city and reflecting it upon exhibited artworks. But Busan Biennale seems to reflect partly an attempt for new place marketing or urban reimagineering as a part of postmodern culture, even thought it has been planned to be an authentic stage or public-place art for citizens. This paper is to examine Busan Biennale 2006, held from Sep.16 to Nov.25 in Busan main theme of which is 'everywhere', constituted with three major projects: the Contemporary Art Exhibition, Sea Art Festival, and the Busan Sculpture Project. Ths paper considers first some implications of the transformation of modem to postmodern city, focusing on spatial representation of the city and public place art, and then tries to evaluate whether Busan Biennale is really embedded in the local authenticity and esthetic imagination for citizen or not. As concluding remarks, this paper suggests that Busan Biennale would be continuously developed, when it is oriented more towards local public-place art for citizens with their active participations rather than towards urban reimagineering strategy to make and promote an image of Busan as a global city.

In this study, there has been investigated the simulation of irradiation dose using Monte Carlo methodology and experimental substantiation for the biological control of wooden cultural property. In the evaluation of fungal contamination on wooden cultural property, Dongyae, from exhibition storage, Aureobasidium pullulans was mainly identified. But these microorganisms were completely inactivated by 20 kGy gamma irradiation. For dosimetry simulation of Dongyae, Monte Carlo methodology with MCNP was used. The real dosimetry was measured using alanin dosimeters (at 7 different points on the front plan and 7 points on the back plan). Simulated and experimental results are compared and good agreement is observed. These result shows that irradiation can offer biologic control of wooden cultural property by optimal irradiation dose through high penetration power and Monte Carlo simulation.

Formaldehyde(HCHO) may have a damage effect on Korean traditional textiles, because concentration is high and occurrence frequency is frequent at the exhibition room and storage area. Total 20 specimens were prepared using 4 different materials (silk, cotton, ramie, hemp) after dyeing with 5 colors (undyed, red, yellow, blue, black). The specimens were exposed to HCHO gas in the test chamber. The gas acceleration test was conducted to identify the deterioration of Korean traditional textiles according to HCHO concentration(0.5, 1, 10, 100, 500ppm), to temperature-humidity condition at HCHO 500ppm, and deterioration conditions at HCHO 500ppm. Optical, chemical, and physical evaluation was carried out after the exposure. The results, color difference, grey scale rating, formate($HCO_2{^-}$) of some textiles increased at 500ppm, while pH decreased at 500ppm. Also, color difference, grey scale rating, formate($HCO_2{^-}$) of some textiles increased double damage at high temperatures & humidity, high humidity condition. But, damages of accelerated degradation textiles were slight, because of degradation degree and degradation products. The results suggest that determined the damage to the korean traditional textile, damage level, damage-weighted condition, damage to accelerated degradation textiles. In addition, formaldehyde damaged to yellowing of red textiles, bleaching of accelerated degradation textiles, formic acid damaged to bleaching of total 20 specimens.

This study aims to identify priorities in book curation service that the teacher librarians perceive important through the AHP (Analytic Hierarchy Progress) method by comparing the jobs of teacher librarians with those of curators and selecting the contents and areas of book curation service provided by school libraries. For the purpose, this study categorized the book curation service areas by class and analyzed the priorities in the book curation service areas in the school libraries by applying the AHP method on the teacher librarians who are the personnel in school libraries. As a result, the priorities in the upper-tier class were turned out to be information services, improvement of expertise, information resources, management, and promotion & marketing in that order. The priorities in the lower-tier evaluation areas were shown in the order of survey & research, Q&A, self-development, exhibition, budget allocation, connecting with experts, trend analysis, reading education, human resources, planning, collaboration class, marketing services, book status, online promotion, offline promotion, and facilities & environment. Based on the results, this study suggested the following plans to provide effective book curation services in school libraries: grasping characteristics of school library users, setting classification criteria for book curation, and finding reader participation-oriented book curation service.

Keiji Kobo is a unique self-generated design research group in Japan, which was founded in 1928 when Bauhaus movement was in its peak, and which lasted ten years until the end of the Second World War, when any activity of the group became virtually impossible due to the war. With insight to see the future, the group aimed at Modern Design advocating a new spirit in architecture, and played a significant role in prosperity of Japanese Modern Design assimilating Western design trends. Pursuing of craft works for everyday life--practical furniture works--Keiji Kobo actively executed various projects to realize modern philosophy. The range of the works of this group was very large: survey, mock-up, experiment, research, exhibition, lecture, order-based sale, advertising and writing. The works of the group were oriented to serious academicism, not compromising with commercialism. Considering the peculiar political situation such as Japanese Militarism, the spirit of functionalism that the group pursued was surprisingly academical and pure. This group was relatively small and clumsy, which lasted as short as around ten years. However, strong motivation was in their seemingly quiet movements, and the influence of the group cannot be underestimated even with today's criteria. There were a number of pioneers who contributed to today's prosperity of Japan and Keiji Kobo can be estimated to be one of the pioneers in the field of design. It was found that the contemporary intellectuals hoped that the committment and activity of the group would contribute to modernization of the life quality of ordinary people. In a sense, Keiji Kobo can be estimated to be a little Japanese equivalent for Bauhaus that could not fully bloom.

The Fourth Industrial Revolution, centered on intelligence and information, began to take hold in 2016. This study uses virtual reality technology, which is the most popular technology of the Fourth Industrial Revolution. The purpose of this study is to explore a Virtual Walk-through method, which can be easily applied to landscape architecture. At present, virtual reality technology is widely used in the fields of games, emergency training, and architectural design. However, in the field of landscape architecture, it is still in the development stage. In addition, most of the traditional ways to display virtual reality use 2D images, but such methods have some limitations. Therefore, this research addresses the three stages of "design-exhibition-experience" and puts forward a new simple method called 'Virtual Walk-through' that breaks from traditional landscape design exhibitions. The results show that compared with traditional methods, virtual reality has many advantages, such as the freedom of experience, a diversity of viewing angles, information supply, interaction, etc. It can show high quality images and effects, which are suitable for landscape design. It provides an evaluation method for garden design that can be utilized in the future. It is simple and has value as it can reflect the method and the expected effects. Virtual reality technology can bring an infinite number of prospects to the development of landscape architecture.
