The purpose of this study is to understand the architectural space of Donggung(東宮), the Prince's Palace, and Dongjo(東朝), the King's Mother and Queen's living space, in the early Joseon Dynasty. The Royal palace can be divided into three parts, political space for king, living space for king and his family and government office. So first, we should to understand the characteristics of each space in the Royal Palace. Up to now we have looked at the architectural space of Donggung(東宮) and Dongjo(東朝) in Gyeongbokgung(景福宮), one of the Royal Palace, the result of this study is as followings. Donggung which was living space for Prince consisted of Jaseondang(資善堂), Seunwhadang(承華堂) and Kyejodang(繼照堂) in the era of King Sejong Kyejodang was demolished and Seunwhadang was destroyed by fire in King Jungjong era and was not rebuilded. This buildings The buildings consisted of Jeondang, Whudang, main gate, hapmun(閤門) and corridor or fence Donggung and Dongjo was separated wall Dong consisted of many buildings for Queen dowager, Queen and many royal concubines The arrangement of Donggung and Dongjo was assumed like as the Fig2.

대기중에 부유하고 있는 입자들의 광흡수량을 측정할 수 있는 기법을 소개한다. 본 연구에서 사용된 기법은 광열분광법이다. 광흡수 측정에 있어서 광열 기법의 장점은 광산란에 둔감할 뿐만 아니라 광산란 계수의 영향을 받지 않고 광흡수 계수를 직접적으로 측정할 수 있다는 것이다. 공기중 부유물질의 흡수 계수 측정의 시간 상수는 10 초이며, 실시간으로 고속도로 주변에서 흡수 계수를 측정하였다. 자동차 경주용 트랙, 공항, 또는 연구소 정문 등 차량 통행량이 많은 지역에서의 흡수 계수가 높게 측정되었는데, 이는 카본 부유물 입자에 의한 영향이라고 판단된다.

Optimal operation of a combined sewer network with distributed storage facilities aims to use the whole retention capacity of all reservoirs efficiently before overflows take place somewhere in the considered network system. An efficient real-time network control (RTNC) strategy has been emerging as an attractive approach for reducing substantially the overflows from a sewer network compared to the conventional fixed or manually adjusted gate setting method, but the related concrete framework for RTC development has not been throughly introduced so far. The main goal of this study is to give a detailed description of the RTNC systems via reviewing several guidelines published abroad, and finally to suggest methods for the proper application of RTNC on distributed storage facilities. Especially, this study is focused on emphasizing the importance of hierarchical structure of RTNC system that consists of three control layers (management, global control and local control). Further, with regard to the global control layer which is responsible for the central overall network control, the wide-ranging details of two components (adaption and optimization layers) are also presented. This study can provide the valuable basis for the RTNC implementation in the particular sewer network with distributed multiple storage facilities.

Water losses in irrigation canals are mainly estimated as the sum of conveyance and delivery water loss. The losses occur via the evaporation, infiltration, gate operation and water distribution processing. Recently, the study regarding these water losses are not satisfactory enough, also delivery water loss has not been mainly considered on field design. The objective of this study is to investigate and analyze the volume of water loss in irrigation canals considering condition of actual farm land. A field measurement was performed at four research sites, which are managed by Korea Rural Community & Agriculture Corporation, to evaluate conveyance and delivery water loss for 2 years. The measurement was performed by canal type, size and designed flow using the inflow-outflow method at a major points such as start and end of each canal, derivation point of canal and inlet of paddy fields. Results of this study showed that water loss ratio in lateral canals was bigger than that of main canal unlike current design standard and the loss decrease as flow increase. The total of water loss ratio including conveyance and delivery water loss in several irrigation canals ranged between 33.25 and 45.0%.

The control of the data retention time is a main issue for realizing future high density dynamic random access memory. The novel junction process scheme in sub-micron DRAM cell with STI(Shallow Trench Isolation) has been investigated to improve the tail component in the retention time distribution which is of great importance in DRAM characteristics. In this' paper, we propose the new implantation scheme by gate-related ion beam shadowing effect and buffer-enhanced ${\Delta}Rp$ (projected standard deviation) increase using buffered N-implantation with tilt and 4X(4 times)-rotation that is designed on the basis of the local-field-enhancement model of the tail component. We report an excellent tail improvement of the retention time distribution attributed to the reduction of electric field across the cell junction due to the redistribution of N-concentration which is Intentionally caused by ion Beam Shadowing and Buffering Effect using tilt implantation with 4X-rotation. And also, we suggest the least requirements for adoption of this new implantation scheme and the method to optimize the key parameters such as tilt angle, rotation number, Rp compensation and Nd/Na ratio. We used MEDICI Simulator to confirm the junction device characteristics. And measured the refresh time using the ADVAN Probe tester.

Seowon(書院) was an institute for education and sacrificial rite, established privately in rural villages throughout the middle period of the Chosun dynasty(1392-1910), where scholars researched classic studies, cultivated personal characters in accordance with the Neo-Confucianism, nurtured young disciples, and performed rites at a secluded shrine where spiritual tablets of honorees were housed. This study examines the architectural characteristics of Pilamseowon(筆巖書院) in Chans'seong, Chollanamdo Province, Korea. Through the study, the architectural characteristics of Pilamseowon were found as follows: First, Pilamseowon moved twice since it had been established. Second, through the moving, the area of Pilamseowon was expanded and buildings were added. Third, some buildings of Pilamseowon reflect the previous condition of the seowon site. Take Hwakyeonroo(廓然樓) as an example, which is the main entrance pavilion of Pilamseowon. Pavilion is an appropriate type of building in sloped site. Before Hwakyeonroo was moved to the present site, it was located on sloped site, where Hwakyeonroo accordingly took the pavilion type of building. Present site condition of Pilamseowon is plane, nonetheless, Hwakyeonroo has the pavilion type of building, which reflects the previous condition of the building site. Forth, Pilamseowon consists of six spatial domains and each domain has its own entrance gate to outer area.
