This study explores the types of relationships between 410 adult children and their elderly parents based of exchange theory and the Konstanz model. In terms of the exchange of emotional, instrumental, and economic support based on exchange theory, the types of relationships identified included "support offers," "reciprocity," and "support benefits." In terms of conflict, intimacy, support offers, support benefits, and support obligations for adult children based on the Konstanz model, the type of relationships with the father included "an intimate exchange," "conflictual distance," "a conflictual sense of duty," and "a flexible exchange." The type of relationships with the mother included "an intimate exchange," "conflictual distance," "separate distance," and "a conflictual offer." There were no distinct characteristics of relationship types based on exchange theory. However, there were differences in characteristics of relation types based on the Konstanz model by gender. These results have important implications with respect to the Western model.

This paper is a series of study for the development of rural elementary school facilities model applying to the regional characteristics. Therefore, main theme of this paper is to pile up and analysis of elementary school facilities data in Po Cheon through a series of actual survey and interview with teachers. The results are summarized as follows ; First of all, in case of Po Cheon, it needs to study for urban model type as well as rural elementary school facilities model type. Second, extension type of buildings has separated as three types-zigzag extension type, vertical & horizontal extension type, separate building type. But another characteristics, such as type of site plan, type of corridor and module of classroom unit, outdoor space and elevation design, are monotonous. Third. the results of this analysis show that it is desirable to locate houses for teachers within boundaries. Finally, the future paper needs to be studying more various module of classroom unit, extension type, space program, type of floor plan and site plan.

In the areas highly exposed to earthquakes, concrete-filled steel tube columns (CFSTCs) are known to provide superior structural aspects such as (i) high strength for good seismic performance (ii) high ductility (iii) enhanced energy absorption (iv) confining pressure to concrete, (v) high section modulus, etc. Numerous studies were reported on behavior of CFSTCs under axial compression loadings. This paper presents an analytical model to predict ultimate load capacity of CFSTCs with circular sections under axial load by using multivariate adaptive regression splines (MARS). MARS is a nonlinear and non-parametric regression methodology. After careful study of literature, 150 comprehensive experimental data presented in the previous studies were examined to prepare a data set and the dependent variables such as geometrical and mechanical properties of circular CFST system have been identified. Basically, MARS model establishes a relation between predictors and dependent variables. Separate regression lines can be formed through the concept of divide and conquers strategy. About 70% of the consolidated data has been used for development of model and the rest of the data has been used for validation of the model. Proper care has been taken such that the input data consists of all ranges of variables. From the studies, it is noted that the predicted ultimate axial load capacity of CFSTCs is found to match with the corresponding experimental observations of literature.

We present a statistical model for the path loss of ultrawideband (UWB) channels in indoor environments. In contrast to our previously reported measurements, the data reported here are for a bandwidth of 6GHz rather than 1.25GHz; they encompass commercial buildings in addition to single-family homes (20 of each); and local spatial averaging is included. As before, the center frequency is 5.0GHz. Separate models are given for commercial and residential environments and, within each category, for lineof sight (LOS) and non-line-of-sight (NLS) paths. All four models have the same mathematical structure, differing only in their numerical parameters. The two new models (LOS and NLS) for residences closely match those derived from the previous measurements, thus affirming the stability of our path loss modeling. We find, also, that the path loss statistics for the two categories of buildings are quite similar.

The study was conducted to determine if variation in protein yield can be explained by expressions of early lactation somatic cell score (SCS) and if prediction can be improved by including SCS among the predictors. A data set was prepared (n = 663,438) from Wisconsin Dairy Improvement Association (USA) records for protein yield with sample days near 20. Stepwise regression was used requiring F statistic (p < .01) for any variable to stay in the model. Separate analyses were run for 12 combinations of four seasons and first three parities. Selection of SCS variables was not consistent across seasons or lactations. Coefficients of detennination ($R^2$) ranged from 51 to 61% with higher values for earlier lactations. Including any expression of SCS in the prediction equations improved $R^2$ by < 1 %. SCS was associated with milk yield on the sample day, but the association was not strong enough to improve the prediction of future yield when other expressions of milk yield were in the model.

In this paper, we introduce about a new class to analysis of partial discharge signal based on Fuzzy model. We can early diagnose life of power cable through detection of partial discharge signal. However, partial discharge signal detector is difficult because of partial discharge signal is very non-linear. Also, it is very difficult work that separate partial discharge signal from noise. We constructed partial discharge accumulation detection system that use Labview for detection of non-linear partial discharge signal. And analyzed partial discharge signal that is detected by Labview system utilizing Fuzzy model.

Traditional External Insulation Finishing System(EIFS) is applied to apartment construction by performing structural framework and insulation finishing work sequentially. Separate execution of the three works increases construction cost and duration. Concurrent construction method of EIFS, which performs framework and insulation finishing work simultaneously, is introduced in order to solve these problems. However, the introduced method is exposed to the risk of construction delay caused by bottlenecks due to interacting processes and resources. Therefore, this paper presents a simulation model suitable for estimating work productivity of the concurrent construction by considering predecessor and successor processes to optimize resource allocation and minimize construction delay.

The Youngwal 1, Youngwal 2 and Youngchun gaging stations are observed flood flow and low flow during Mar. 2004~Oct. 2004. They are observed water stages and flow velocities for flood and low flow. The observed data are used to derived rating curve and equations. The HEC-RAS model is applied for hydraulic modeling in gauging stations. The model is designed to perform one-dimensional hydraulic calculations for an river improvement plan in a full network of natural and constructed channels, and is comprised of a graphical user interface(GUI), separate hydraulic analysis components, data storage and management capabilities, graphics and reporting facilities.

It is fact that many research is advanced about management and security of water resources according to serious problem which is raising its head that conservancy and management of water resources development of population and industry. Ground water of water resources is the source of water resources security with surface water, so it have to be continuous exploitation and research however, until now it researched in separate way from surface water, and it become connect each other for the research in actual condition in recent times. The research analyzed the recharge at the SWAT model, interpreted by used GMS/MODFLOW model for ground water flow change.
