Since the site chosen for GBAS ground system will have a direct effect on the performance of the GBAS, the GBAS ground system siting is mightily important in the GBAS installation process. Therefore, in this paper, the major equipment of the GBAS ground system is introduced and a formal process is described for the identification and evaluation of candidate GBAS sites. Also, this paper described detail siting requirements for the GBAS ground system such as reference receiver, VDB antenna and shelter respectively.

Before GBAS ground systems is installed at the airport, the site survey is needed to determine the suitability of proposed GBAS candidate sites depending on the siting requirements. Therefore, analysis of GPS signal reception environment, one of the site survey steps, is required. In this paper, the number of visible satellites, GPS signal strength, multipath error, radio frequency interference and predicted availability were analyzed using the GPS data of Gimpo International Airport measured by PortaSAT equipments and the analysis results were represented.

This study investigated the status of kitchen of units in elderly housing facilities and the housing needs of residents. Compared with a lot of comprehensive and alternative studies on elderly housing facilities until now, specialized studies of behavior of elderly housing life and detailed dimensional study have hardly made. Therefore we intend to examine the status of kitchen planning on representative elderly housing facilities in Korea. As the methods of this study, we executed a field study into 4 representative elderly housing facilities in Korea. We visited each 2 units out of the outstanding 4facilities and surveyed the total 8 kitchens. Then we analyzed the space planning and kitchen furniture design of them and the state of kitchen commodities, and measured the kitchen equipment. In addition, we executed interview about satisfaction, preference, use from the residents. As a result, we could find out that depending on whether residents were sewed with meal offered from the facilities or not, the pattern of usage and commodities were quite different. It is necessary to supply the simplest spaces just for preparing some refreshment and tea are suitable. And for the self-cooking residents, much larger cabinets and utility rooms are additionally needed. Safety and functional aspect were quite well designed. Washing machines are usually built-in the kitchen cabinets, and residents are satisfied with this arrangement. We hope that the supplementary study about old people habit and behavior will be a good data of kitchen planning for Korean-type elderly housing units of facilities.

Due to the impact of birth rate, the school age population decreases year by year, and as a result, the Ministry of Education conducts the layout adjustment for middle and primary schools and cancels substantial rural schools. Nearly half of the cancelled and idle schools are not applied till now. Combining the practical demand of local residents, it is quite necessary to make use of the idle schools effectively again. Consequently, field investigation is conducted for the architectural status of 28 idle schools in Pingle County of Guilin, Guangxi, and detail investigation and analysis has been carried out for the different scales of schools from various aspects, including the covered area, traffic, building construction, space composition, degree of aging, etc. The investigation result shows that small teaching schools are remote, being small in scale, single in space and serious in aging. Complete primary schools are close to the villages and towns, being large in scale, abundant in space, and well preserved. The teaching schools are between the previous two types. Meanwhile, it is generally convenient in traffic, and good in structure. It can provide fundamental data for the future utilization and study.

This study aims to examine the characteristics of landscape through the analysis of location and the landscape of Gugok while also conducting the empirical study through the literature review, field study, and digital analysis of the Okgung Gugok. Oksan Gugok is a set of songs set in Ogsan Creek(玉山川)or Jagyese Creek(紫溪川, 紫玉山), which flows in front of the Oksan Memorial Hall(李彦迪), which is dedicated to the Lee Eong-jeok (李彦迪). We first ascertained the location and configuration of Oksan Gogok. Second, we confirmed the accurate location of Oksan Gogok by utilizing the digital topographic map of Oksan Gogok which was submitted by Google Earth Pro and Geographic Information Center as well as the length of the longitude of the gravel measured by the Trimble Juno SB GPS. Through the study of the literature and the field investigation, The results of the study are as follows. First, Yi Eonjeok was not a direct composer of Oksan Gugok, nor did he produce "Oksan Gugokha(Music)". Lee Ia-sung(李野淳), the ninth Youngest Son of Tweo-Kye, Hwang Lee, visited the "Oksan Gugokha" in the spring of 1823(Sunjo 23), which was the 270th years after the reign of Yi Eonjeok. At this time, receiving the proposal of Ian Sung, Lee Jung-eom(李鼎儼), Lee Jung-gi(李鼎基), and Lee Jung-byeong(李鼎秉), the descendants of Ian Sung set up a song and created Oksan Gugok Music. And the Essay of Oksan Travel Companions writted by Lee Jung-gi turns out being a crucial data to describe the situation when setting up the Ok-San Gugok. Second, In the majority of cases, Gogok Forest is a forest managed by a Confucian Scholar, not run by ordinary people. The creation of "Oksan Bugok Music" can be regarded as an expression of pride that the descendants of Yi Eonjeok and Lee Hwang, and next generation of several Confucian scholars had inherited traditional Neo-Confucian. Third, Lee Jung-eom's "Oksan Donghaengki" contains a detailed description of the "Oksan Gugokha" process and the process of creating a song. Fourth, We examined the location of one to nine Oksan songs again. In particular, eight songs and nine songs were located at irregular intervals, and eight songs were identified as $36^{\circ}01^{\prime}08.60^{{\prime}{\prime}}N$, $129^{\circ}09^{\prime}31.20^{{\prime}{\prime}}E$. Referring to the ancient kingdom of Taojam, the nine-stringed Sainam was unbiased as a lower rock where the two valleys of the East West congregate. The location was estimated at $36^{\circ}01^{\prime}19.79^{{\prime}{\prime}}N$, $129^{\circ}09^{\prime}30.26^{{\prime}{\prime}}E$. Fifth, The landscape elements and landscapes presented in Lee Jung-eom's "Oksan Gugokha" were divided into form, semantic and climatic elements. As a result, Lee Jung-eom's Cho Young-gwan was able to see the ideal of mountain water and the feeling of being idle in nature as well as the sense of freedom. Sixth, After examining the appearance of the elements and the frequency of the appearance of the landscape, 'water' and 'mountain' were the absolute factors that emphasized the original curved environment at the mouth of Lee Jung-eom. Therefore, there was gugokga can gauge the fresh ideas(神仙思想)and retreat ever(隱居思想). This inherent harmony between the landscape as well as through the mulah any ideas that one with nature and meditation, Confucian tube.
