느린 페이딩 채널에서 공간-시간 트렐리스 부호의 준최적 복호법
신상섭,김영주,Shin Sang-Seop,Kim Young-Ju 한국통신학회 2006 한국통신학회논문지 Vol.31 No.8C
공간-시간 트렐리스 부호에서 기존에 제안된 ML(maximum likelihood) 복호법과 PRC(principal ratio combianing) 복호법을 아우르는 준최적 복호법인 GPRC(generalized PRC) 기법을 제안한다. GPRC는 수신안테나들을 K개의 그룹으로 나누어 각 그룹에 PRC 기법을 적용하는 것이다. GPRC에서는 수신안테나 그룹핑 방법이 여러 가지이므로 K가 정해졌을 때 최적의 그룹핑 규칙을 제안한다. 이때 최종 성능 차이를 간단하게 예측할 수 있는 성능지표(PI, performance index)를 이용할 수 있다. 특히 수신안테나 간 상관(correlation)이 있을 때 무선 채널 계수를 구하고, 성능 지표를 평가한다. 마지막으로 컴퓨터 시뮬레이션으로 이론적 성능을 검증한다. We present a suboptimum decoding method for space-time trellis codes, which include maximum $likelihood(ML)^{[1]}$ and principal ratio $combining(PRC)^{[2]}$, over quasi-static flat fading channels. In the proposed scheme, the receive antennas are divided into K groups and the PRC is applied to each group, showing a flexible performances between ML and PRC. When K is determined, we also propose the optimum grouping rules and performance index(PI), which simply anticipate the relative performances. Moreover the performances are also evaluated when receive antennas are correlated. Finally, Computer simulations corroborate those theoretical results.

신상섭,김현욱,박영관 한국전통조경학회 2012 한국전통조경학회지 Vol.영문 No.10
This study is basic research for physical, semantic recovering of Hageowon garden (by Gwon Yijin 權以鎭) in musu-dong, yuseong-gu, Daejeon. In order to understand how to generate symbolic value and how to reflect natural materials in the garden, this study examines the process of garden planning. The study on the Traditional Landscape Architecture Plan of Hageowon Garden are as follows. First, Creating Hageowon garden was completed through 3 steps. 1 step had implemented between 1707~1708 when paternity tomb and Byulup, Yuhoidang were newly constructed. When 2 step(1713~1719), Naboji(納汚池, in 1713) was created, <Banhwonwongi(盤桓園記)> was written, Samgeunjeongsa(三近精舍, in 1707) & Yuhoidang(有懷堂) were rebuilt. 3 step was period of garden completing when Gwon Yijin after resigning a governor to retire to the country. He expanded Hageowon and wrote <Hageowongi(何去園記)> in 1727. Second, Hageowon is devided as 3 sections. The 1 section(to cherish and transmit maltreatment) is inner garden around Yuhoidang reaching to the Naboji(納汚池, in 1713), Gosudae(孤秀臺), Odeokdae(五德臺), Dokyung(桃徑). The 2 section is Byulup garden(別業園林) composed with Jangwoodam(丈藕潭, going up 8 to 9 stairs from Dokyung), Yocheondae(繞千臺), Sumanheon(收漫軒), Hwalsudam(活水潭) and Sumi Waterfall(修眉瀑布) on the east. The 3 sectionis east outer area of Hageowon garden consisting of Baegyeongdae(拜景臺), Mongjeong, Unwa(雲臥), Artificial mountain(enjoyment area that substitute to utopia in fairyland). Third, there are 17 species plants including pine, maple, azalea, royal azalea, peach tree, persimmon tree, pomegranate, four seasons flowers, Japanese azalea, peach, lotus, chrysanthemum, peony root, peony etc. introduced in Hageowon. Fourth, methods using nature rocks as it is, linking water culture factor(Hwalsudam, Sumi Waterfall) and applying Seokyeonji and flower beds are used for stone figures. Especially, the methods of Chukgyeongwon(縮景園), the artificial hill(石假山) are characterized as poetic landscape with ancient literature. Fifth, Characteristics of water system is to experience five senses such as introducing water considering nature mooring and geographical features(valley on the east), functional roles to link three sections(Mongjeong<夢井>-Hwalsudam-Sumi Waterfall) with a sense of rhythm, the methods of substitution to connect Hwalsudam, Mongjung, pond with philosophical meanings, temporary experience five senses by using sense of sight, hearing (rainbow, bubble etc).

This thesis is to newly understand the value and the meaning of Chonju Palkyong(全州八景) by the specific gravity in making a counter-proposal in other to improve the landscape identity of modern city and at the same time. I intended to group the grafting device for the preservation and regeneration of modern history cultural environment through the interpretation of landscape construction. The meaning system of Chonju Palkyong showed the symbolic system which a landscape construction, four directions and two places has and exhibited the landscape shape possessing a luxuriant local feature peculiar to Chonju, preserving visual bound language of a classical Palkyong. Especially, it implies the use of the substantial landscape experienced factor, the expressions about natural phenomena and the matter which has melted human living circumstances. The landscape construction and it's form show the system which forms the different time field, a far landscape and a mid distance landscape and a near landscape, etc., under the visual, psychological, scenic influenced area, preserving the feature of the similar and typical type of Sosang Palkyoung(瀟湘八景) which intended to seek the local reappearance of the famous site experienced type and natural matter which famous place and local conduct were combined. The object space of Chonju Palkyong area representing the nature of historical landscape cultural assets, pushed by the greater part of the development based theory, shows injured aspects, but needs to play a part to seek such a up-to-date successive plan as the reconstruction of the destroyed historical landscape area which motivated Palkyong, the establishment of useful area, the embodiment of the cultural identity of Palkyong area and the becoming of the educational cultural life space. The analysis of the landscape construction of Chonju Palkyong and the grouping of the modern successive plan which I considered in this thesis, will be able to become a fundamental data to carry out the preservation of historical landscape and the landscape plan in the city.

‘Sukchunjeahdo’ illustration-book, which was left by Han, Pil-gyo(韓弼敎 : 1807~1878)in the late Joseon Dynasty, includes pictorial record paintings containing government offices, Eupchi, and Feng Shui condition drawn by Gyehwa(界畵) method Sabangjeondomyobeop(四方顚倒描法) and is the rare historical material that help to understand spatial structure and landscape characteristics. Youngyuhyun(永柔縣) and Sincheongun(信川郡) town, the case sites of this study, show Feng Shui foundation structure and placement rules of government offices in the Joseon Period are applied such as 3Dan 1Myo(三壇一廟 : Sajikdan, Yeodan, Seonghwangdan, Hyanggyo), 3Mun 3Jo(三門三朝 : Oeah, Dongheon, Naeah) and Jeonjohuchim(前朝後寢) etc. by setting the upper and lower hierarchy of the north south central axis. The circulation system is the pattern that roads are segmented around the marketplace of the entrance of the town and the structure is that heading to the north along the internal way leads to the government office and going out to the main street leads to the major city. Baesanimsu(背山臨水 : Mountain in backward and water in front) foundation, back hill pine forest, intentionally created low mountains and town forest etc. showed landscape aesthetics well suited for the environmental comfort condition such as microclimate control, natural disaster prevention, psychological stability reflecting color constancy principle etc. and tower pavilions were built throughout the scenic spot, reflecting life philosophy and thoughts of contemporaries such as physical and mental discipline, satisfied at the reality of poverty, returning to nature etc. For government office landscape, shielding and buffer planting, landscape planting etc. were considered around Gaeksa(客舍), Dongheon(東軒), Naeah(內衙) backyard and deciduous tree s and flowering trees were cultivated as main species and in case of Gaeksa, tiled pavilions and pavilions topped with poke weed in tetragonal pond were introduced to Dongheon and Naeah and separate pavilions were built for the purpose of physical and mental discipline and military training such as archery. Back hill pine tree forest formed back landscape and zelkova, pear trees, willow trees, old pine trees, lotus, flowering trees etc. were cultivated as gardening trees and Feng-Shui forest with willow trees as its main species was created for landscape and practical purposes. On the other hand, various cultural landscape elements etc. were introduced such as pavilions<Nu(樓), Jeong(亭), Dae(臺), Gwan(觀), Gwan(館), Gak(閣), Heon(軒) etc.>, pond serving as fire protection water(square and circle), stone pagoda and stone Buddha, fountains and wells, monument houses, flagpoles etc. In case of Sincheongun town forest(邑藪), Manhagwan(挽河觀), Moonmujeong(文武井), Sangjangdae(上場岱) and Hajangdae(下場岱) Market place, Josanshup<(造山藪 : Dongseojanglim(東西長林)>, Namcheon(南川) etc. were combined and community cultural park with the nature of modern urban park was operated. In this context, government office landscape shows the garden management aspect where square pond and pavilions, flowering trees are harmonized around side pavilion and backyard. Also, environmental design technique not biased to aesthetics and ideological moral philosophy and comprehensively considering functionality (shielding and fire prevention, microclimate control, etc.) and environmental soundness etc. is working. 조선후기 문신 한필교(1807~1878년)가 관직을 역임했던 읍치를 대상으로 제작한 『숙천제아도(宿踐諸衙圖)』 화첩의 평안도영유현과 황해도 신천군 읍치를 분석 자료로 활용하여 실증사료로서의 가치추적, 공간구조 등의 전형성 정립, 관아조경 및 문화경관특성 도출 등을 시도한 연구결과는 다음과 같다. ‘풍수형국도’ 성격을 겸하며 사방전도묘법으로 그려진 『숙천제아도』의 읍치도는 조선시대 지방고을의 터잡기와 공간구조는 물론환경설계원칙 등을 파악할 수 있는 사료적 가치를 지닌다. 고을 치소(邑治)는 남북 중심축선에 위계를 설정한 배산임수 체계이며, 전조후침(前朝後寢)의 관아시설, 그리고 3단1묘의 제례처 등 도성에 준한 토지이용과 배치규범을 적용하고 있다. 교통요충지에자리한 고을 치소는 어귀 장터마당을 결절점으로 안길을 따라 북쪽으로 향하면 관아 문루에 다다르는 노단경이 형성되고, 고갯길또는 물길을 따라 외부 바깥길로 이어지는 체계를 갖는다. 즉, 동선체계는 바깥길-고갯길-어귀길-장터마당-안길-또는 샛길로수용력과 위계에 따라 분절되며 3거리 길로 접합되는 양상이다. 지방관아의 토지이용은 3조(三朝)의 개념(외조, 치조, 연조)을 반영한위계적 구성인데, 동헌의 후원과 객사의 별원을 포함하여 3문3조2원(三門三朝二園)의 공간체계를 보여준다. 고을의 뒷동산 소나무숲, 명당수인 남천, 안산(案山)에 해당하는 조산(造山), 비보숲 읍수(邑藪) 등 풍수적 경관짜임이 작용되었는데, 겨울철 북서풍 차단과여름철 상승기류 형성 등 에너지 보존, 색체 항상성, 자연재해 방지와 심리적 안정성 등 쾌적성 조건에 부합되는 환경지속성이 추출된다. 한적한 곳에 자리한 향교는 별도의 원림을 가꾸지 않았으며, 누정은 심신수양, 안분지족, 자연회귀 같은 상징적 가치, 정치적행사와 윤리관 반영, 유흥상경 등 문화경관 양상이 다양하게 표출되는데, 객사에는 기와를 얹은 와정(瓦亭)이, 동헌과 내아에는 네모꼴연못을 두고 소박한 모정(茅亭)이 도입되는 차별성을 보여준다. 관아에 지표경관으로 문루가 자리하고, 군사훈련 및 심신수양을 겸한사정(射亭)이 필수시설로 도입되었다. 아사의 앞뜰은 네모꼴 마당(庭)으로 조경처리를 하지 않은 반면, 정청의 뒤뜰(後園)과 객사의별원(別園) 등은 장식적으로 가꾸었다. 이러한 관아조경은 공간 성격 및 위계를 반영하되 기능적 지속성(차폐와 방화, 미기후조절 등)과심리적 건전성, 상징성 등을 복합적으로 고려한 경관미학이라 하겠다. 한편, 소나무, 느티나무, 배나무, 버드나무, 향나무(또는 노송), 연(蓮), 화목(花木) 등이 조경식물로 활용되었는데, 환경심리적 가치가 부가된 배후숲, 조산숲과 비보숲 등과 함께 건전한 문화경관요소로 자리매김하고 있다. 이러한 분석결과를 일반화 시킬 수 있느냐 하는 문제는 조선시대 읍치의 공간구조 및 환경설계 원칙이 제도적 틀 안에서 정형성으로 작용되고 있어 연구의 한계를 극복할 수 있으리라 판단된다.
