Acceleration time history used in the seismic analysis of nuclear porter plant structure should envelop a target power spectral density (PSD) function in addition to design response spectrum. Current regulation guide defines the target PSD function only for the U.S. URC RG 1.60 Design Response Spectrum. This paper proposes a technical scheme to obtain the target PSD function compatible with generally defined design response spectrum. The scheme includes the methodology for design-spectrum compatible motion history in order to minimize the variation of the derived target PSD function. The PSD calculation procedure follows simple and practical methods allowed within regulation. Effectiveness of the proposed scheme is identified through an example problem. The design response spectrum In the example is based on U.S. NRC RG 1.60 but amplifies the spectral acceleration amplitudes above 9Hz. The target PSD function with little variation can be constructed with the reduced time history ensemble.

The purpose of this paper is to suggest new direction to the historical research society of Korean architecture by epistemological discussion. Korean architectural history at present, without question of history for what, for whom, and how, is regarded as 'history for the past' only 'to describe past' or 'to collect correct data' However, history is beyond that; history ought to suggest a direction of present and near future. Moreover, architecture is not pure but applied knowledge, that is, focused to 'how to build'. Therefore, past historical knowledge by research should influence to present design. In order to do that, history of mere data collection should change direction to the history of meaning by interpretation, and then, of finding design principle. The principle used in architectural community becomes theory in scientific research community, and finally is unified to 'theory of practice'. Creative history should be substituted for retrospective history reusing historical reservoir, at the specific situation of Korea; tradition has been discontinued drastically and Western method imported to the point of being culturally-colonized. Some expmples of altanative history are suggested at the end of this paper as conclusion.

More than a year has already passed since the Gyeongbuk Hemp Regulation Free Zone Project was implemented, and it is time to supplement and review the deficiencies in production history management for the domestic hemp industry after the Free Regulatory Zone. In this study, the current status and characteristics of cannabis history management in the Gyeongbuk Hemp Regulation Free Zone project were investigated, and problems with current history management were derived using service design tools such as pilot interviews, shadowing, and Customer journey map. The case of the cannabis production system and the CTS recommended for the legal cannabis market in Oregon, a leading country, was compared and analyzed, and the direction was to secure safety through production cycle history management suitable for growth characteristics, efficient technology application for real-time management, and history information sharing. Through this study, it is expected that it will help improve the current hemp production history management system and properly settle the history management system of domestic hemp industrialization in the future.

From 1998 Seoul city is being rebuilt for 'the city which people want to go around on foot'. Many streets only for cars have been transformed for pedestrians. In addition to that streets are built not only just to pass by, but also enjoy themselves, so 8 Streets in Seoul have been redecorated as 'Streets of History and Culture'. These Streets are chosen because they have their own unique history or culture, so they are remodeled with lightings, exhibition pavilions or sign postings etc except manhole covers. Even these 8 streets have manhole covers; they are not particular, just same as like other streets. For most streets manhole cover is an essential component of them, but it is mostly omitted to be designed in particular. For the most time some of the standard manhole covers are installed in a street. Taking a look at manholes in Minneapolis city, they inform visitors what the landmark, landscape, symbol, representative flower or tree of the city is. Sometimes they are designed by famous artists and become art which all pedestrian can enjoy. If manhole covers in 'the streets of history and culture' are designed to represent its history or culture, visitors will get information about there easily and enjoy their design. To foster manhole cover designs, the government office should co-work with professional designers or design societies and encourage people to spend a certain amount of the construction cost to design manhole covers. At school designing manhole cover can be handled in an art class and besides can have a class in the field, streets to observe manhole cover designs. Getting more concern of manhole cover design, competitions and exhibitions are able to be held.
