박훈(Park, Hoon) 한국도시설계학회 2015 도시설계 : 한국도시설계학회지 Vol.16 No.2

마곡중앙공원 조성계획은 기존 마곡워터프론트 계획이 백지화 된 이후 다양한 논의를 거쳐 보타닉가든으로 방향성이 결정되었으며, 식물원과 공원이 결합되는 새로운 타입의 도시공원으로 방향이 제시되었다. 마곡이 가지고 있는 지형적 특성과 역사적 의의, 그리고 도시공간에서의 입지특성은 공원조성을 위한 기본 철학과 조성원칙으로 발전하였으며, 공간계획으로 구체화 되었다. 이와 같은 개념은 식물원, 호수공원, 열린숲공원, 생태천이원 등 4개의 존으로 영역화하여 세부공간계획으로 구체화 된다. 특히 식물원 부분은 핵심적인 공간으로 약 128,000㎡의 규모로 조성되어 새로운 명소가 될 것으로 기대하며, 도시공원에서 경험할 수 있는 호수와 잔디마당은 도시민들이 쉴 수 있는 여가의 공간으로 조성될 것이다. 또한 마곡중앙공원은 내ㆍ외적 성장의 개념을 바탕으로 조성될 것이며, 100년의 시간을 통해 성장하게 될 것이다. 이와 같은 종합적인 계획은 기존 선행하여 연구되었던 현대공원설계의 특성에서 제안한 여섯 가지 전략과 밀접하게 연관성을 갖고 있음을 확인할 수 있었다. After the Magok Waterfront Plan was annulled, discussions led to the decision to develop Magok Central Park as a botanical garden. It was proposed that the botanical garden and park be combined to create a new type of city park. The geographical characteristics and historical implications of Magok and the location’s urban spatial characteristics were developed into a basic philosophy and a composition principle for a park design and then shaped into a spatial plan. The concept divides the space into four zones, including a botanical garden, a lake park, an open forest park, and an ecological succession area, which are given shape through a detailed spatial plan. The botanical garden, in particular, as a core space that occupies 128,000㎡, is expected to become a new attraction. A lake and a lawn in the city park will become a leisure area where citizens can relax. Moreover, Magok Central Park will be built based on the concept of internal and external growth, and it will grow over 100 years. It was identified that this comprehensive plan is closely related to six strategies for modern park design as delineated in existing studies.

마곡워터프론트 조성계획은 한강르네상스계획과 연계하여 마곡지구를 특화된 수변도시로 발전하기 위하여 정책적으로 제시된 공모로 시작되었다. 도시 환경과 공원의 특성을 살려 제안 당선된 Heart of Magok is Nature of Living Water안은 다음과 같은 특성을 지닌다. 첫째, 유수지, 청정호수, 주운수로, 생태공원 등의 시설을 중심으로 테마형 공원을 구성한다. 둘째, 녹색제방(Green Levee)이 공원의 중심 기능을 담당하며, 상징적 역할을 한다. 셋째, 공원의 순환동선, 물에너지의 순환 등이 종합적인 공원의 지속가능성을 확보하고 있다. 넷째, 공원과 주변도시와의 접근성을 높여 이용의 편의성을 고려한다. 다섯째, 시간에 따라 성장하는 공원의 이상을 제안하고 있다. 이상과 같은 계획 특성은 공원의 이용성을 높이며, 워터프론트로서의 역할에 젓실하고, 도심에서 공원의 역할을 한 단계 높이는 역할을 기대하게 하였다. 그러나 이후 도시환경의 변화에 따라 다양한 발전 전략을 모색하게 되었으며, 특히 경제성, 환경성 등을 중심으로 각각 육상공원의 확보, 업무·상업기능의 강화, 그리고 공원의 환경성 강화 등의 방안이 고려되고 있다. The development plan of Magok waterfront has begun with the public design contest with an intention that the Magok District is to advance into a specialized waterside city in connection with the Hangang Renaissance Plan. The winning work, the ‘Heart of Magok is Nature of Living Water’ plan, contained the characteristics of urban environment and park as follows. First, it builds up the theme park around the facilities of detention reservoir, clean lake, navigation channel, ecology park and others. Second, the green levee undertakes the central function of the park as well as symbolic role thereof. Third, it secures the sustainability of a general park with the circulation of park, circulation of water energy and the like. Fourth, it considers the convenience of utility by enhancing the accessibility with parks and surrounding cities. And fifth, it proposes the more than a simple park that grows in time. The foregoing plan characteristics heightens the utility of park, substantiate the role as water front, and expects to have the role to one notch upgrade in the roles of urban parks. And, along with the effort, following the changes of Magok District, base facilities and urban environment, the changes of Magok Water Front may be sought with respect to change into ground park, plan to strengthen the environment, strengthening of commercial and office functions, and this is considered in relations to the comprehensive development plan of Magok District. This is considered as a part of seeking for diverse improvement plan in accordance with the changes in urban environment, and it seeks for possibilities through seeking changes of program together with the physical changes in lake parks and ground parks.

박훈(Hoon Park),김혜미(Hyemi Kim) 인문사회과학기술융합학회 2018 예술인문사회융합멀티미디어논문지 Vol.8 No.4

Theme parks have evolved for various purposes, and as the culture of leisure and relaxation expands, the number of those looking for them is also continuously rising. In particular, theme parks need to be differentiated depending on the type of location, distance from the city center, and characteristics of surrounding environment, and each main space is differentially planned according to the required program. The C theme park examined in this study has limitations in terms of using the given space, while its contents have a big possibility. So this study suggests the following conclusions to overcome the limitations. First, reconstruction through the reorganization of the whole spatial structure is necessary in order to have significance of the theme park. Second, it needs to be used through active linking of internal and external facilities. Third, a plan is needed to increase the usability by linking each facility. Fourth, an essential approach of the theme park is needed through the spatialization of each unit facility. Through the approach above, it is possible to improve the unique spatial system of theme parks and to create environment for usability and various experiences. Especially, it is important to approach through landscape planning such as planting conditions. 테마파크는 다양한 목적을 가지고 발전해 왔으며, 여가와 휴식의 문화가 증가하면서 이를 찾는 이들 또한 지속적으로 증가하고 있다. 특히 테마파크는 입지 유형과 도심으로부터의 거리, 주변 환경의 특성에 따른 차별화되는 계획이 필요하며, 각각의 주요 공간들은 요구되는 프로그램에 따라 차별적으로 계획된다. 본 연구를 통해 살펴본 C 테마파크는 자체적으로 가지는 컨텐츠는 가능성이 큰데 반하여 실제적으로 주어진 공간을 활용하는 측면에서 한계를 갖고 있으며, 이를 개선할 수 있는 다음과 같은 결론을 제시하였다. 첫째, 테마파크의 의의를 갖추기 위하여 전체 공간구조의 개편을 통한 재구성이 필요하다. 둘째, 단지 내·외부 활용가능한 시설의 적극적 연계를 통한 이용이 필요하다. 셋째, 각각의 시설을 연결하여 이용성을 높이는 계획이 필요하다. 넷째, 각각 단위 시설단위의 공간 영역화를 통해 테마파크의 본질적 접근이 필요하다. 이상과 같은 접근을 통해 테마파크가 갖는 고유한 공간체계로의 개선과 함께 이용자의 이용성과 다양한 체험을 위한 환경마련이 가능하며, 특히 식재환경 등 조경 계획을 통한 접근이 중요성을 갖는다.

박훈채(Hun Chae Park),최항석(Hang Seok Choi),김석준(Seock Joon Kim),최연석(Yeon Seok Choi) 대한설비공학회 2010 대한설비공학회 학술발표대회논문집 Vol.2010 No.6

The SCR catalyst in coal-fired power plant is eroded by the collision of fly ash on the catalyst face. However the erosion of SCR catalyst by the collision of fly ash has not been fully studied, especially in terms of fluid dynamics. Hence, in the present study, we focus on the gas and solid flows inside the SCR catalyst duct and their consequent effect on the erosion characteristics by fly ash. For this purpose, computational fluid dynamics is applied to investigate the two-phase flows and to evaluate the erosion rate for different flow and particle conditions. Also, the erosion rate and pressure drop of honeycomb shape are compared with corrugate shape. From the results, when the collision velocity of fly ash is increased, the erosion rate is enhanced and the erosion rate is decreased if the particle diameter is increased. It is noted that the erosion rate and pressure drop of the corrugate shape are lower than those of the honeycomb shape.

박훈,윤경식,황인갑,Park, Hun,Yoon, Kyung-Sik,Hwang, In-Gab 한국통신학회 2004 韓國通信學會論文誌 Vol.29 No.6A

본 논문에서 0.5$\mu\textrm{m}$ GaAs MESFET을 이용하여 5GHz대 무선랜에 사용 가능한 MMIC 가변이득 저잡음 증폭기를 설계 및 제작하였다. 이득과 잡음성능이 우수한 증가형 GaAs MESFET과 선형성이 좋은 공핍형 MESFET 조합의 캐스코드 구조로 저잡음 증폭기를 설계하기 위하여 Turlington의 점근선법을 이용하여 MESFET의 비선형 전류 전압특성에 대한 거동 모델 방정식을 도출하였다. 이로부터 캐스코드 증폭기의 공통 소오스 FET는 4${\times}$50$\mu\textrm{m}$ 크기의 증가형 MESFET으로 공통 게이트 FET는 2${\times}$50$\mu\textrm{m}$ 크기의 공핍형 MESFET으로 설계하였다. 제작된 가변이득 저잡음 증폭기의 잡음지수는 4.9GHz에서 2.4dB, 가변 이득범위는 17dB이상, IIP3는 -4.8dBm이며, 12.8mW의 전력을 소비하였다. This paper describes the design and fabrication of an MMIC variable gain LNA for 5GHz wireless LAN applications, using 0.5${\mu}{\textrm}{m}$ gate length GaAs MESFET transistors. The advantages of high gain and low noise performance of E-MESFETS and excellent linear performance of D-MESFETS are combined as a cascode topology in this design. Behavioral model equations are derived from the MESFET nonlinear current voltage characteristics by using Turlington's asymptote method in a cascode configuration. Using the behavioral model equations, a 4${\times}$50${\mu}{\textrm}{m}$ E-MESFET as a common source amplifier and a 2${\times}$50${\mu}{\textrm}{m}$ D-MESFET as a common gate amplifier are determined for the cascode amplifier. The fabricated variable gain LNA shows a noise figure of 2.4dB, variable gain range of more than 17dB, IIP3 of -4.8dBm at 4.9GHz, and power consumption of 12.8mW.

인산감수성(燐酸感受性)이 다른 대두(大豆)를 암모니움태, 질산태, 뇨소태질소의 배양액에 길러 엽(葉)과 근(根)에서 RNA, DNA 및 기타 인산형태(燐酸形態)를 정량하였다. 인산감수성(燐酸感受性)인 품종(品種)은 내성(耐性)인 품종(品種)보다 모든 질소원(窒素源)에서 산가용무기린산함량(酸可溶無機燐酸含量)이 높았다. 산가용무기린산(酸可溶無機燐酸)은 요소배양(尿素培養)에 가장 높았고 질산태배양(窒酸態培養)에서 가장 낮았다. 전인산(全燐酸) 함량(含量)은 산가용무기린(酸可溶無機燐)의 증가(增加)에 의(依)하여 가장 영향(影響)을 받았다. 산가용무기린산(酸可溶無機燐酸)이 증가(增加)하면 산가용유기린산(酸可溶有機燐酸), 지질인산(脂質燐酸) 리보핵산인(核酸燐)과 잔여인산(殘餘燐酸)이 증가(增加)하는 경향(傾向)이나 데옥시 리보핵산(核酸)은 변화가 거의 없었다. 질산태배양식물(窒酸態培養植物)에서 전린산(全燐酸)에 대(對)한 리보 핵산인(核酸燐)이나 데옥시리보핵산인(核酸燐)의 백분률(百分率)은 암모니움 배양(培養)의 그것보다 두배가 되었으며 질소원(窒素源)에 관계(關係)없이 내성품종(耐性品種)에서 역시 높았다 전산가용인(全酸可溶燐)에 대(對)한 산가용유기린(酸可溶有機燐)의 백분률(百分率)은 인산감수성(燐酸感受性)이 적을수록 적었다. 인산감수성(燐酸感受性)은 인산대사(燐酸代謝)풀의 상대적(相對的) 크기에 의존(依存)됨을 나타낸다. 전건물생산량(全乾物生産量)은 전인산함량(全燐酸含量)과 부상관(負相關)이고 (-0.84로 1% 수준유의(水準有意)) 산가용무기린(酸可溶無機燐) (-0.84로 1% 수준유의(水準有意))이나 잔여인(殘餘燐) (-0.69로 5% 수준유의(水準有意))과도 부상관(負相關)이었다. 산가용유기린(酸可溶有機燐)을 지질인(脂質燐), 리보핵산인(核酸燐) 및 데옥시 리보핵산인(核酸燐)과 정(正)의 상관성(相關性)을 보이나 잔여인(殘餘燐)과는 부(負)의 관계(關係)였다. 리보핵산인(核酸燐)은 지질인(脂質燐)과만 유의정상관(有意正相關)(0.63, 1% 수준(水準))을 갖는다. 질소원(窒素源), 품종(品種) 그리고 인산대사(燐酸代謝)풀 간(間)에는 유의성(有意性)있는 (1%수준(水準)) 교호작용(交互作用)이 있었다. 인산감수성(燐酸感受性)과 암모니움해독(害毒)은 에너지 대사면(代謝面)에서 동일(同一)한 것으로 보였다. 즉(卽) 전자(前者)는 아데노신 3 인산(燐酸)을 아데노신 2 인산(燐酸)으로의 轉換(에너지방출)을인산(燐酸) 포텐샬을 통해 저해하며 후자(後者)는 아데노신3 인산(燐酸)의 생성(生成)(에너지 저장(貯藏))을 저해하는것 같다. RNA, DNA and other phosphorus fractions were determined in the leaf and root of soybean plants different in phosphorus sensitivity grown in $NH_4-N,\;NO_3-N$ and urea medium. The phosphorus sensitive cultivars contained higher ASIP (acid soluble inorganic phosphorus) than the tolerant cultivars with all nitrogen sources. ASIP was highest in the urea treated plants and lowest in the nitrate treated plants. Total phosphorus content was mostly affected with increase in ASIP. When ASIP increased, acid solsuble organic phosphorus(ASOP), phospholipids (L-P), RNA-P, residual phosphorus (R-P) tended to increase, while DNA-P showed little change. The percent RNA-P or DNA-P of total phosphorus in the nitrate treated plant was twice that in the ammonium treated plant, which were also higher in tolerant cultivars regardless of nitrogen sources. The percent ASOP in total acid soluble phosphorus $(ASOP/ASP{\times}100)$ decreased as phosphorus sensitivity decreased. Indications are that phosphorus sensitivity depends on the relative sizes of phosphorus metabolic pools. Total dry matter yield was negatively correlated with total phosphorus (r=0.84 significant at 0.01P), ASIP (0.84 significant at 0.01P) and residual phosphorus (0.69 significant at 0.05P). ASOP showed positive correlation with L-P, RNA-P and DNA-P but negative with R-P. RNA-P was significanly correlated only with L-P (0.63 at P=0.01). There was significant interaction (0.01) among nitrogen sources, cultivars and phosphorus metabolic pools. Phosphorus sensitivity and ammonium toxicity appear to be same in view of energy metabolism, that is, the former inhibits the conversion of ATP to ADP (energy releasing) through phosphate potential while the latter inhibits ATP formation (energy storing).

University campus has grown and developed along with history of human in connection with transition characteristics of city. In particular, reflecting the features in the times, the masterplan should explore its main roles today when international growth of university is pursued. In particular, center core and quad space, focusing on main components of campus such as main building, student union hall and main lecture facility, are the prototype of campus components and have been pursued to have importance in terms of shape and function as traditional campus space strategy. Recently, however, new strategy has been proposed to explore orders of campus utilizing the underground space focusing on main universities. Design of Hana Plaza of Korea University and Bekyangro of Yeonsei University, the targets of this study, actively explore this strategy. This study analyzed such strategies in terms of concept of space to obtain space, design trend of main universities at home and abroad, and viewpoint of integrated masterplan proposal. Conclusions from this study are as follows. First, concept of quad and center space found in the design of traditional campus is reinterpreted into new design aspects through development of underground space. Second, development of underground space is approached to overcome the limit of existing campus and to present the vision of universities 100 years ahead. Third, ever-changing complicated urban environment has been reflected in space configuration of campus and positioned as strategy to implement this as modern construction technique. Third, implementation of pedestrian-oriented campus has been pursued by reinforcing utilization of inclined topography of urban environment in Korea. This enables to obtain spaces for main activities of students and to implement the space where student support facilities are concentrated and activities are performed actively. Such features can be presented as conclusions of this study.

Abnormal grain growth in alumina was investigated during sinter-HIP process for better understanding of pressure effect on microstructural development. Abnormal grain growth of monolithic alumina was observed near surface region rather than interior region of specimen. Finite element analysis was used to estimate the pressure distribution developed in the specimen. Pressure distribution analysis was in good agreement with grain size distributjion in the specimen. The results of finite element analysis provided that abnormal grain growth monolithic alumina was resulted from the inhomogeneous pressure distribution in the specimen. MgO addition in alumina was effective for the suppression of abnormal grain growth in alumina under inhomogeneous pressure distribution during sinter-HIP process.
