  • Recently, microgrid (MG) has been proposed as one of the most critical solutions for various energy problems. For the optimal and economic operation of MGs, it is very important to forecast the load profile. However, it is not easy to predict the load accurately since the load in a MG is small and highly variable. In this paper, we propose an artificial neural network (ANN) based method to predict the energy use in campus buildings in short-term time series from one hour up to one week. The proposed method analyzes and extracts the features from the historical data of load and temperature to generate the prediction of future energy consumption in the building based on sparsified K-means. To evaluate the performance of the proposed approach, historical load data in hourly resolution collected from the campus buildings were used. The experimental results show that the proposed approach outperforms the conventional forecasting methods.

  • Tree-ring chronologies can be used to date historical buildings by matching them with the chronologies of living trees or previously dated samples. Tree-ring dating gives a calendar year to each tree ring and produces the felling dates of logs or woods which had been used for buildings. In Korea, several chronologies of Japanese red pine(Pinus densiflora Sieb. et Zucc., 'sonamu' in Korean), a major species for the wooden building materials, have been developed and used for dating historical buildings. In this study, Tongmyungjeon Hall of Changkyung Palace in Seoul was dated by tree rings. The present Tongmyungjeon Hall was known to be reconstructed in A.D. 1834 after burned-out in A.D. 1790. We sampled total of 122 wood samples which were replaced during the repair process in 2002-2003. Felling dates of the samples were determined by the dendrochronological crossdating method. Crossdating method employs graphic comparison of the master patterns (ring-width chronologies of known dates) with those of the sample chronologies of unknown dates. Tree-ring dates confirmed that the reconstruction of 1834 utilized second-handed timbers as well as fresh-cut ones. The felling dates of wooden floor frames were mostly A.D. 1913, indicating the 'Ondol' floors were changed to the wooden floors around 1914 when the Japanese rulers brutally destroyed the royal Korean Palaces and transformed palace buildings to their offices or exhibition halls after occupying Korea in 1910. This study proved that tree-ring dating was a useful and accurate method to identify the critical dates for the history of Korean traditional buildings.

  • In 2018, the Cultural Heritage Administration of Korea introduced a new system that registers national cultural heritage in street and district units. Yeongju City's Modern Historical and Cultural District was selected as the first trial region. This grouping method breaks through conservation and utilization limitations of cultural heritage in individual building units. Thus, the issue is how will such historical and cultural spaces be grouped, conserved and managed. Hence, this study identifies the current situation of buildings in the Modern Historical and Cultural Street of Yeongju and conducts an experimental survey. Based on this, the types of modern architecture were classified, and the architectural groups were extracted and categorized to preserve and utilize the architecture. For these purposes, priority groups were determined by evaluating them based on five criteria: archetype, placeness, politicalness, typicality and originality. The modern architecture in the Modern Historical and Cultural Street of Yeongju have undergone many changes. The residential transformation of small and medium-sized cities during modern times can be understood as a process of settlement and nativization.

  • Architecture is usually seen as a product of art and technology. However, most historical buildings also exemplify various sophisticated principles of mathematics. Outstanding examples of architecture around the world such as Seokguram, Daewoongjun of Bulguksa, Muryangsujeon of Buseoksa, and the Parthenon provide students with a great opportunity to study their underlying mathematical properties and principles. The activity of identifying and investigating such mathematical principles in historical buildings enables students to realize that mathematics is a practical subject, and thus provides justification for the study and importance of mathematics. For the purpose of this study historical architecture was reviewed with this in mind in order to develop STEAM education materials focused on elementary school mathematics. The result of this study is as follows: first of all, appropriate examples of historical architecture were selected on the basis of the 2009 revised curriculum's content and teaching goals. These involved chapters on 'proportion', 'symmetry', 'movement of figures', 'building blocks', and 'triangles'. Secondly, a meta-analysis was performed on the historical buildings that clearly illustrate mathematical principles. Thirdly, STEAM education materials focused on elementary mathematics using architectural examples were developed which made actual application in classrooms possible. And lastly, surveys of professional groups were conducted to verify whether the produced materials were suitable teaching resources.

  • Museum Architecture, passing through modem times, have been requested to make changes in order to respond to the necessities of current times as well, so that they come to develop various kinds of programs other than a mere exhibition. That is, museum began recognizing the diversity of activities available in the spaces and the openness to the public. And tried to keep up with the changes by linking the museum buildings with local community in urban architecture as a result. Conversion design is methodology aims at reforming old buildings into a museum or revitalizing buildings of historical significance into exhibition center, so that it made possible to utilize the texts of historical, cultural cities, which in turn contribute to the diversity of urban architecture and protection of buildings in environmental crisis. In the sense, the paper analyzes the life-long contribution and dedication of Carlo Scarpa, an Italian architect, in the conversion of museum architecture, and studies the style, techniques, and features witnessed from his architectural works, and finally offers an insight and a directing post to take advantage of diverse ways likely applicable in our urban architectures. Scarpa's features in his museum architecture are classified as follows: First, contrasting expression of reiteration and side by side to express the continuity of time Second, he conveyed implicated meanings through inserting contracted factors of the locality and traditionality. Third, his interest in formative works and handicraft had an influence on shaping conversion space Finally, expression of accidentally to change of a point of view.

  • Superstructures and isolation systems of seismically isolated buildings located close to active faults may observe increased seismic demands resulting from long-period and high-amplitude velocity and displacement pulses existent in near-fault ground motions as their fundamental periods may be close to or coincident with these near-fault pulse periods. In order to take these effects into account, the 1997 Uniform Building Code (UBC97) has specified near-source factors that scale up the design spectrum depending on the closest distance to the fault, the soil type at the site, and the properties of the seismic source. Although UBC97 has been superseded by the 2015 International Building Code in the U.S.A., UBC97 near-source factors are still frequently referred in the design of seismically isolated buildings around the world. Therefore it is deemed necessary and thus set as the aim of this study to assess the necessity and the adequacy of near-source factors for seismically isolated buildings. Benchmark buildings of different heights with isolation systems of different properties are used in comparing seismic responses obtained via time history analyses using a large number of historical earthquakes with those obtained from spectral analyses using the amplified spectrums established through UBC97 near-source factors. Results show that near-source factors are necessary but inadequate for superstructure responses and somewhat unconservative for base displacement response.

  • This study examined public building remodeling projects in France. Through investigating cases of ancient buildings remodeled in France, the study aimed to provide fundamental data and analysis for remodeling public buildings. Accordingly, seven cases were analyzed in terms of remodeling methods, architectural characteristics, methods of conservation, and restoration of ancient historical buildings, as well as a change of usage of an existing building. As a result, this study found the criteria of French ancient building remodeling. The remodeling methods of an existing building vary in their goals and strategies depending on how the old architectural elements are persevered, as well as how new elements are added to form their unique characteristics. Thus, the remodeling methods are classified into four types based on causes: restoration, extension, renovation and rebuilding. Such methods are used jointly rather than individually. The ancient building remodeling is the process of recreating new functions and new artistic values to preserve the cultural and artistic values of existing historic buildings.

  • The prevention of disasters in cultural property is very important management and historical duties. The reason can't be measured values with monetary scale of our contemporary. Therefore, this paper was considered fire-safety as one of terrible threat-disasters about the wooden buildings. This research deal with 47 cases cultural property wooden building by whole investigation(field survey and interview) in Gangnung province. The most buildings have basic fire extinguisher; ABC powder. A few buildings are rarely installed fire extinguishing equipments; outdoor fire hydrant, heat sensor, ground sprinkler, CO2-hose-reel. But these state is very insufficient for the fire-safety in cultural property wooden buildings. Specially as particular attention in province, forest fire of regional characteristic have close relation with cultural property fire. The majority of factor against forest and building fire is to provide monitoring and security system; CCTV, Fence, Sensor, Alarm and paid guard man against incendiary. Ultimately it is necessary to construct comprehensive disaster prevention system with the organic cooperation such as National Emergency Management Agency, Cultural Heritage Administration, Forest Service, local government officials and regional citizen.
