As a faithful study about the intended plan of builder, this article studied the Dosanseodang(陶山書堂) which is located in the Dosanseodang(陶山書堂). The Dosanseowon is one of the representative Yi-Dynasty' Seowons. Through the review of $\ulcorner$The Writings of Toegye$\lrcorner$. It is found several intended plan of the Dosanseodang(陶山書 堂) as follows. 1. When Toegye located the site of the Dosanseodang in the Dosan, using four criteria such as 1) geographical characteristics(地 理), 2) hills and waters(山水) 3) form and orientation of valley, 4) so-cial characteristics. 2. In the Dosan area, the location of Seodang was determined by the physical characteristics of the valley(orientation and entrance), not by the concept of Fung-sui(風水). 3. The whole spatial structure of Seodang area formed triangle, and the Dosanseodang was located at the angular point of the triangle. 4. The landscape elements of the Dosanseodang falled into the three landscape hierarchy such as a front view, a middle view, and a distance view. Besides the three views, there was a borrowed view which Toegye defined in terms of ownership.

The ships always have had the risk of collision. There are also a number of near-miss situations especially in the congested area such as port entrance, restricted waters and crossing point of the ship's route. In those areas, the navigator might have more stress than other areas. If the collision risk of decided area is calculated, it might be possible to analyse the human factors by using this data. It is also helpful for deciding a position of aids to navigation or any other system for the safety navigation. For this purpose, the model of collision risk with AIS data has been explained in this paper. The calculated result from the proposed model has been examined by using the simulation.

In this study, the bottom tracking observation in the tidal entrance within Mokpo coast is performed using ADCP in order to estimate net flux of water mass and tidal prism. First of all, observed rawdata was conducted coordinate rotation considering rotation of the cross-section in order to derive the predominant velocity component. And observed rawdata is converted into Sigma coordinate with normalization and blank zone data near the water surface and bottom is interpolated using von-Karman equation. Net flux of water mass is calculated quantitively from the interpolated data, calculated results show that these represent well characteristic of ebb superiority at Mokpo coast as well as change of net flux of water mass with tide. Also, by complementing the definition of tidal prism proposed in past studies, the definition of tidal prism including tidal condition was re-established. Based on the new definition, tidal prism at a tidal entrance using bottom tracking data with ADCP is estimated quantitively for the first time domestically. The results are compared with those for results of previous study, calculated results were in good agreement with previous studies.

Multispectral scanner data collected by LANDSAT-1 over the mid West Sea of Korea were analyzed and interpreted for delineation of coastal features and turbidity distribution patterns during different portions of the tidal cycle. Imagery from two successful LANDSAT-1 overpasses of the area in October 1972 and in October 1973 had been used to prepare schematic maps of coastal features and turbidity distributions. Color composite imagery of LANDSAT MSS 4, 5 and 7 gave the best representation of shorelines, coastlines and tidal flats. MSS 5 imagery was most effective in differentiating relative turbidity levels through density slicing techniques. Referring to the tidal power development of Garolim Bay, the basin area measurements assuming dyke construction at the bay entrance, have been carried out on the coastal reature maps comiled from LANDSAT imagery, and those results were correlated with existing data. General areal patterns of surface turbidity distribution in the study area revealed close similarity with bathymetry of the area. Synoptic circulation patterns were also well discriminated from the LANDSAT imagery using the suspended sediment as a tracer.

It is estimated that the need to build health facilities for the elderly will grow in the near future as the Korean society is aging. Thus the study on the spatial composition of 22 facilities as well as on the cases of health facilities for the elderly in Japan, where public health and medicare for aged people are well taken care of, was conducted and the following are the results: 1. As of 2000, there was one facility for every 8,000 and 1,100 aged citizen under long-term care, and these facilities secured beds enough for $8\%$ of those who need long-term care. 2. The spatial composition was categorized into general living space, long-term care, management, provision, and home assistance, and housing was provided. Moreover, the space was divided according to their nature of use, the arrangement, the form of entrance into the building, moving line inside, the relationship with the health facilities and their characteristics are analyzed based on different users, managers, moving line including that of provision of food, the relationship between different spaces with different functions as well as on the relationship between locations of each space. 3. The total capacity, building area and actual area of the welfare facilities for the elderly are analyzed, and area per person, detailed area for each space, percentage of each living space for long-term care patients and characteristics of recuperation room are suggested.

Research method was a case study as narrative method through in-depth interviews around 21 sufferers of elder abuse in rural area and the researcher interviewed them directly. Conclusively, the majority of sufferers of elder abuse were physically very low in the ADL(activities of daily living) and had been bereaved with no spouse. The relations of abused parents and the adult children were much disagreed and divided as unrecovered. Their economic reliance and physical reliance were much overlapped and the majority of them were low educational background and low income level. In case of the abused old people, they had severe low self respect and melancholy, so they considered severely suicide so much as invaluable as their existing value. In spite of over 80.5 years old average, the abuse action had continued for 6 months to 50 years long and the intensity of the abuse was more strengthened. The majority of abused old people refused mostly the entrance of social welfare facilities for elders and also they desired to live in present living area and their own houses.

This study aims to analyze the mixing characteristics of hydrogen considered as a new fuel for internal combustion engines. As the physical property of helium gas is similar to that of hydrogen, helium gas was used in this study. To analyze the steady and unsteady behavior of jet, helium gas was injected into the stationary atmosphere at the normal temperature and pressure. Concentration of helium gas in the center of jet flow is in inverse proportion with axial distance from the nozzle tip. This agrees with the free jet theory of Schlichting. The relative equation for dimensionless concentration to radial/axial distance the axial distance of potential core region, the cone angle a of the jet flow and the relative equation for arriving distance of the front of jet flow to the lapse of time are obtained. But free jet theory of Schlichting in the dimensionless concentration is not in agreement with the present experimental results of the distance of the radial direction. It needs more study. When the arrival frequency of jet flow is used as a parameter, the transition area changing from unsteady flow area into steady flow area becomes gradually wider downstream, but its ratio for the whole unsteady flow area gradually decreases.

The purpose of this study is predicted easily the entrance surface dose (ESD) in chest digital radiography. We used two detector type such as flat-panel detector (FP) and IP (Imaging plate detector). ESD was measured at each exposure condition combined tube voltage with tube current using dosimeter, after attaching on human phantom, it was repeated 3 times. Phantom images were evaluated independently by three chest radiologists after blinding image. Dose-area product (DAP) or exposure index (EI) was checked by Digital Imaging and Communications in Medicine (DICOM) header on phantom images. Statistical analysis was performed by the linear regression using SPSS ver. 19.0. ESD was significant difference between FP and IP($85.7{\mu}Gy$ vs. $124.6{\mu}Gy$, p=0.017). ESD was positively correlated with image quality in FP as well as IP. In FP, adjusted R square was 0.978 (97.8%) and linear regression model was $ESD=0.407+68.810{\times}DAP$. DAP was 4.781 by calculating the $DAP=0.021+0.014{\times}340{\mu}Gy$. In IP, adjusted R square was 0.645 (64.5%) and linear regression model was $ESD=-63.339+0.188{\times}EI$. EI was 1748.97 by calculating the $EI=565.431+3.481{\times}340{\mu}Gy$. In chest digital radiography, the ESD can be easily predicted by the DICOM header information.

This study aims to identify the actual condition of local food stores that serve as a regional activation space within the highway rest area. It analyzes and examines user awareness, and presents desirable directions for the establishment of new local food stores and improvement of existing facilities. The research method was conducted as follows: the status of 226 rest areas were examined which were installed on national highways, location conditions and convenience facilities. Second, a physical survey was conducted on 116 local food stores(floor area, location) and a user awareness survey on 63 local food stores. The results of the analysis and review have been concluded as follows. First, it is necessary to consider the establishment of a local food store in order to promote the local community by using various cultural and environmental conditions in the highway rest area, and to secure a public space to promote exchanges with local residents and revitalize the local economy. Second, considering the continuous increase of highway users, location, and traffic conditions, diversification of convenience functions including local food stores should be considered even if it is a medium and small highway rest area. Third, the floor area of local food stores is generally planned within a range of $75m^2$ to $125m^2$, and its location should be integrated with the rest area as much as possible. Inevitably, when you need to construct separately at the exit or entrance, you need to consider a unique design that ensures accessibility and visibility.
