Fire was and remains a great threat to historic buildings of wood. This threat is omnipresent and often results to irreparable property losses especially cultural heritages. Fire of historic buildings continues to increase every year. The purpose of this study is to preserve a life safety, historical heritage and architectural & cultural values by pursuing for fire safety in the historical buildings. This study shall employ two research methods: a literature review and field survey methods. The literature review shall focus on the observations of characteristics noted in fire codes. The field survey shall cover a heat analysis and fire protection equipment. A method is proposed to investigate fire codes related historical building, reported fire history Fire Codes and Regulations for modern buildings are not always applicable on the historic buildings. Old buildings, and some new buildings with architectural, historical or cultural importance may have values which cannot be measured on a monetary scale. Their protection against the damage caused by fire is considered to be one of the basic moral duties of society. It is strongly recommended, therefore, legislation for fire safety in historical buildings must be extended to a complementary relationship with 'active' fire protection measures, to provide safety in real historical building in real fire situations. The development and application of performance based Codes and the Fire Safety Engineering approach seems to be a rather reasonable and effective way to deal with this historical buildings.

Historical dramas are changing in response to the public who wants more dramatic development, and historical costumes are also expressed in a modern sense. The purpose of this study is to examine the modernization of historical costumes in historical dramas and how the modernization of historical costumes in historical dramas is fostered from the learner's point of view with suggesting implications. As a result of this study, first, the essential problem with the modernization of historical costumes was the excessive modern transformation that undermines historical facts in historical dramas. Second, the negative perceptions of the modernization of historical costumes in historical dramas included the loss of the unique Korean identity, decreased immersion in drama, and the educational influence of media. Positive perceptions focused on the increased interest through raising awareness of traditional culture, compromises on changes in the times, and increased visual play of the public. Third, the implications of the modernization of historical costumes in historical dramas require the awareness improvement of participants in historical drama and a thorough preliminary investigation by the costume designer on the historical costume, an in-depth study of traditional costumes, a systematic educational approach, viewers' attention, and government effort.

Gunpowder was invented as a result of discovering the fact that potassium nitrate acts as an oxygen carrier in the process of manufacturing traditional medicine by heating the mixture of potassium nitrate and sulfur. Rapid progress was made in dynamite manufactring technology as a result of development of basic chemistry in Europe. However, recently the demand for dynamite has decreased in favor of the ANFO explosive which is improved production technology. This study was attempted to clear the historical facts concerned with the developing process of European eaplosive technology, and intended to submitt the reference materials for researchers.

In this study, we tried to make histo-genetic analyses necessary to identify epistemological obstacles on the function concepts. Historical development on the function concept was analysed. From these analyses, we obtain epistemological obstacles as follows: the perception of changes in the surrounding world, mathematical philosophy, number concepts, variable concepts, relationships between independent variables and dependent variables, concepts of definitions.

This introduction is both a statement of a research problem and an account of the first research results for its solution. As more historical databases come online and overlap in coverage, we need to discuss the two main issues that prevent 'big' results from emerging so far. Firstly, historical data are seen by computer science people as unstructured, that is, historical records cannot be easily decomposed into unambiguous fields, like in population (birth and death records) and taxation data. Secondly, machine-learning tools developed for structured data cannot be applied as they are for historical research. We propose a complex network, narrative-driven approach to mining historical databases. In such a time-integrated network obtained by overlaying records from historical databases, the nodes are actors, while thelinks are actions. In the case study that we present (the world as seen from Venice, 1205-1533), the actors are governments, while the actions are limited to war, trade, and treaty to keep the case study tractable. We then identify key periods, key events, and hence key actors, key locations through a time-resolved examination of the actions. This tool allows historians to deal with historical data issues (e.g., source provenance identification, event validation, trade-conflict-diplomacy relationships, etc.). On a higher level, this automatic extraction of key narratives from a historical database allows historians to formulate hypotheses on the courses of history, and also allow them to test these hypotheses in other actions or in additional data sets. Our vision is that this narrative-driven analysis of historical data can lead to the development of multiple scale agent-based models, which can be simulated on a computer to generate ensembles of counterfactual histories that would deepen our understanding of how our actual history developed the way it did. The generation of such narratives, automatically and in a scalable way, will revolutionize the practice of history as a discipline, because historical knowledge, that is the treasure of human experiences (i.e. the heritage of the world), will become what might be inherited by machine learning algorithms and used in smart cities to highlight and explain present ties and illustrate potential future scenarios and visionarios.

This study aims to develop the education for college students who should perform the social role of the fut ure by conducting trekking activities including the characteristics, history, and culture of Cheonan area and then investigating the sociality and history of 36 college students. Taejosan, Seonggeosan, and Heukseongsan, which are part of the independent ring of Cheonan city, were selected as courses. The training was conducted by six instructors majoring in humanities, history, physical education and medicine. Teachers of humanities and history majors conducted theoretical lectures to raise the historical awareness of Cheonan area related to trekking course. In trekking practice, instructors of physical education and medicine majored in trekking safety education and course progress. Among the social development factors, responsibility, autonomy, and sociality were high. After the education, students recognized that the interest and necessity of history were high in order to understand the present society, thought that they made a lot of development compared to the previous one, and answered that the main development factors of history were the people and that there was a change in perception through this education. This study was composed of the survey after the education, so the psychological characteristics of the individual were not reflected, and it is difficult to generalize it because the number of subjects is small. In the future, more subjects need to be investigated and local residents need to investigate changes in local awareness.

The present study purposed to examine the possibility of developing historicity inherent in places into tourism resources from the view that the history and location of historical cities have the nature of cultural contents. Previous researches on tourism have been focused on tourist facilities, the development of tourist attractions, economic effects, cultural policies, etc. However, the present study makes a cultural approach to historical cities to explore the meaning of places formed through history and the historicity of places, assuming that the temporal and spatial characteristics of Hanseong-bu can be developed into tourism resources. Major places of Hanseong-bu are classified according to their functions and cultural meanings, and these factors are associated with the geographical structure of the area. By landform and cultural characteristics during the Chosun Dynasty, Hanseong-bu is divided into the central part, the boundary area, and the outskirts. In addition, different elements, which can be developed into tourism resources, are found according to the landscape of Hanseong-bu, the character as a dynastic city, the environs inside the wall, and differences among localities reflecting pre-modem lifestyle.

Contradictions often occur between the process of urban modernization and protection of history and culture, which have become the topics of current studies. The development of a city has its past, present and future while history and culture have their continued process. Culture is the sediment of history, left among buildings and merged in life. Exerting a subtle influence on the construction of a city and behaviors of citizens, culture is very important to the urban construction and is also the soul of a city and its buildings. Culture is closely bound up with inhabitants' life and the key to protect well the cultural features is to protect well historical and cultural venues. Qushuiyuan Garden is a venue for local folklore activities. The programming holds that folklore, historical and humane sceneries should be protected and left to our coming generations.
