The results of VE (Value Engineering) analyses are highly feasible proposals that are produced by utilizing the experience and knowledge of professionals from a variety of fields. As such, the results of past similar projects can be useful in new projects. On this basis, it is vital to accumulate the historical data of the results on VE analyses performed at every stage, which are functions, ideas, and proposals. In this research, a data formational system for collecting this historic data was established by categorizing 'Item,' 'Function,' 'Idea,' and 'Proposal' according to VE process, and the data retrieval and the adjusting process were proposed. If the historic data of these are accumulated using the suggested method, it is expected to be useful at the stage of VE process.

The historical drama played on TV in 2003, Daejanggeum is originally based on the short historical record of lady doctor of the palace from the [Jungjong record] of Josun. The drama mixed fiction and historic record well together draw enormous interest and became a novel, musical and animation for children. Also the location of shooting drama became a theme park to attract travelers and the name 'Daejanggeum' was used for products to create great additional value. Most of all, the drama then was exported to overseas and became the representing drama of Korea. Therefore, drama is the representing piece that proved the success of historic data with its application as various modern cultural contents. The analysis of success reason of showed the creation of new modern woman character, fresh selection of the item that suits well in the time of desiring wellbeing, the strong drama scenario with different story development compared to previous historic drama. Also, it used 'one source multi use' method prior to the broadcasting and prepared production of various cultural contents. This success of Daejanggeum means a lot from the point of 'modern acceptance of tradition' to tradition researchers.

The Purpose of this study is to develop the rainfall-delayed response model (RDR Model) which influences the baseflow proportion of rivers as a result of the antecedent precipitation of the previous several months. The assesment of accurate baseflows in the rivers is one of the most important elements for the planning of seasonal water supply for agriculture, water resources development, hydrological studies for the availability of water and design criteria for various irrigation facilities. The Palukan river gauging site which is located in the Pulukan catchment on Bali Island, Indonesia was selected to develop this model. The basic data which has been used comprises the available historic flow records at 19 hydrologic gauging stations and 77 rainfall stations on Bali Island in the study. The methology adopted for the derivation of the RDR model was the water balance equation which is commonly used for any natural catcbment ie.P=R+(catchment losses) -R+(ET+DP+DSM+DGW). The catchment losses consist of evapotranspiration, deep percolation. change in soil moisture, and change in groundwater storage. The catchment areal rainfall has been generated by applying the combination method of Thiessen polygon and Isohyetal lines in the studies. The results obtained from the studies may be summarized as follows ; 1. The rainfall-runoff relationship derived from the water balance equation is as shown below, assuming a relationship of the form Y=AX+B. Finally these two equations for the annual runoff were derived ; ARO$_1$=0.855 ARF-821, ARF>=l,400mm ARO$_2$=0.290ARF- 33, ARF<1,400mm 2. It was found that the correction of observed precipitation by a combination of Thiessen polygons and Isohyetal lines gave good correlation. 3. Analysis of historic flow data and rainfall, shows that surface runoff and base flow are 52 % and 48% (equivalent to 59.4 mm) of the annual runoff, respectively. 4. Among the eight trial RDR models run, Model C provided the correlation with historic flow data. The number of months over which baseflow is distributed and the relative proportions of rainfall contributing in each month, were estimated by performing several trial runs using data for the Pulukan catchment These resulted in a value for N of 4 months with contributing proportions of 0.45, 0.50, 0.03 and 0.02. Thus the baseflow in any month is given by : P$_1$(n) =0.45 P(n) +0.50 P(n-I ) +0.03 P(n-$_2$) +0.02 P(n-$_3$) 5. The RDR model test gave estimated flows within +3.4 % and -1.0 % of the observed flows. 6. In the case of 3 consecutive no rain months, it was verified that 2.8 % of the dependable annual flow will be carried over the following year and 5.8 % of the potential annual baseflow will be transfered to the next year as a result of the rainfall-delayed response. The results of evaluating the pefformance of the RDR Model was generally satisfactory.

The goal of this research is to apply the neural networks models for the disaggregation of the pan evaporation (PE) data, Republic of Korea. The neural networks models consist of generalized regression neural networks model (GRNNM) and multilayer perceptron neural networks model (MLP-NNM), respectively. The disaggregation means that the yearly PE data divides into the monthly PE data. And, for the performances of the neural networks models, they are composed of training and test performances, respectively. The training data consist of the generated data using PARMA (1,1). And, the testing data consist of the historic data, respectively. From this research, we evaluate the impact of GRNNM and MLP-NNM for the disaggregation of the nonlinear time series data. We should, furthermore, construct the credible data of the monthly PE data from the disaggregation of the yearly PE data, and can suggest the methodology for the irrigation and drainage networks system.

This paper describes the application of a wireless sensor network to a 31 meter-tall medieval tower located in the city of Trento, Italy. The effort is motivated by preservation of the integrity of a set of frescoes decorating the room on the second floor, representing one of most important International Gothic artworks in Europe. The specific application demanded development of customized hardware and software. The wireless module selected as the core platform allows reliable wireless communication at low cost with a long service life. Sensors include accelerometers, deformation gauges, and thermometers. A multi-hop data collection protocol was applied in the software to improve the system's flexibility and scalability. The system has been operating since September 2008, and in recent months the data loss ratio was estimated as less than 0.01%. The data acquired so far are in agreement with the prediction resulting a priori from the 3-dimensional FEM. Based on these data a Bayesian updating procedure is employed to real-time estimate the probability of abnormal condition states. This first period of operation demonstrated the stability and reliability of the system, and its ability to recognize any possible occurrence of abnormal conditions that could jeopardize the integrity of the frescos.

The purpose of this study was to search the architectural forms including the residence plan and wooden structure and the measuring unit in building sites named Bang in Gyeong_Ju, the capiatal of Silla dynasty. It includes the following three historic sites: JaMaeJung-ji, the east district of HwangLyong-sa (S1E1) and InWang-dong historic site. Especially, the data from excavating and studying the east district of HwangLyong-sa were very precious and meaningful. The results were as follows: 1) There are individual characteristics at the sites of JaMaeJung-ji, the east district of HwangLyong-sa and InWang-dong. 2) It is assumed that the builldings of the east district of HwangLyong-sa had most various types of plan and various types of wooden structures. 3) There were various types of wooden structures like as symmetrical or asymmetrical style, regular columnar or irregular columnar style and a third purlin location or a forth purlin location. 4) This study also showed there's a high probability that buildings at Bang sites had been built by the Tang dynaty scale. In Silla dynasty, there was similar tendency to BackJe Dynasty in the way that measuring unit changed according to the times.

As ongoing construction of a new municipal government building leads to the destruction of the interior of the Kyungsung Municipal Government Building(currentlySeoul Metropolitan City Hall) despite its enormous historic value, this study aims to identify the unique features of spatial composition and interior design of the Kyungsung Municipal Government Building, which is widely known as a typical example of public architecture of the 1920s. The primary goal is to perform a systemic arrangement of its interior data and define the modern historic implications of its interior design, thereby laying the foundation for a compilation of the history of modern interior design. From a historical perspective, the Kyungsung Municipal Government Building-an explicit symbol of Japanese colonial supremacy-has served as the administrative hub of a hugecity for 19 years during the Japanese colonial rule and for 64 years following Korea's independence from Japan. From the perspective of architectural history, it also represents modern transitional buildingsin their shift from historicism into modernism, as manifested by its reasonable placement of interior space matching well with topographical form, easy access by citizens, open office space, and, excluding decoration, a simple and non-authoritarian exterior. Its interior design style follows Western historicist architecture, whereasits simple interior decoration embodies expressive characteristics of pragmatic simplicity. Such elements are notably found in the Grand Central Hall, the Municipal Head's Reception Room, and the Grand Conference Room.

Although the importance of good conservation of historic sites including ancient royal tombs is wet] aware, still not much attention has been paid for the facilities and systems to preserve those historic sites, which includes precious artifacts as wall paints and carved works, etc. Even the general understanding about the environment of the underground space of tombs is not satisfactory. In the present study, vibration levels due to the operation of an HVAC system to maintain the desired indoor temperature and humidity are investigated experimentally. According to the measured data, the level of vibration inside the present model tomb with the indoor unit inside, showed order of magnitude less values than the Swiss Standards, but still higher than the value suggested by German standards, which is, zero. For the vibration level depends not only on the system design, but also on the installation methods, further study will be pursued for cases including different ways of installation.

Probable Maximum Precipitation (PMP) is essential in the design of hydraulic structures such as dams, weirs and flood control structures. Up to the present, PMP has been derived from any proper single storm which can have a large error. PMP values should be evaluated from many historic heavy storm events from all over the country. Since this can be done at the spots of storm occurring and the calculated PMP from all spots in the country can be correlated. The objectives of this study are therefore to evaluate PMP from historic heavy storm data from 1972 to 2000 by using meteorological method, then to correlate and to present the results using GIS. The maximized rainfall depths can be calculate from depth of heavy rainfall and dew point temperature, and then can be analyzed for each rainfall duration to obtain spatial rainfall distribution by using GIS. The depth-area-duration relationship of maximized rainfall can be obtained and this helps to develop enveloped curves . The results from this study are a set of contour maps of PMP for each rainfall duration for all over the country and the depth-area-duration relationships for the area of 100 to 50,000 km.$^{2}$ at duration of 1, 2 and 3 days.

Although the importance of good conservation of historic sites including ancient royal tombs is well aware, still not much attention has been paid for the facilities and systems to preserve those historic sites, which includes precious artifacts as wall paints and carved works, etc. Even the level of general understanding about the environment of the underground space of tombs is not satisfactory. In Korea, researchers have recently begun addressing the importance of maintaining proper environment for underground space as of ancient tombs and are making efforts to develop suitable HVAC(heating, ventilating and air-conditioning) systems for them. In this study, an HVAC system for a tomb ($D{\times}W{\times}H=1.3m{\times}3.0m{\times}1.2m$) was installed to maintain suitable indoor conditions for conservation of tomb. The temperature and humidity inside the tomb were measured to represent the performance of the installed duct-type HVAC system. Vibration levels due to the installed an HVAC system are alive investigated experimentally. According to the measured data, the level of vibration inside the present model tomb with the duct-type unit showed significantly lower values than the case with the indoor unit inside.
