A Study on the Conservation Activity for Modern Landscape Heritage of the Japanese Institute of Landscape Architecture

박진욱 한국전통조경학회 2018 한국전통조경학회지 Vol.16 No.-

The present study is intended to draw an implication from landscape heritage conservation activities of the Japanese Institute of Landscape Architecture(JILA) via literature survey and interviews. In consequence, the modern landscape conservation activities of the Japanese Institute of Landscape Architecture can be divided into three phases. First of all, the beginning phase was between 1989 and 1997. In the phase, the Japanese Institute of Landscape Architecture established the Landscape Heritage Conservation Committee, showing its first academic-society-level actions. Secondly, the preparatory phase was between 1998 and 2009. A variety of academic activities were conducted during the phase, and the activities included establishment of the Landscape Heritage Research Committee and five subcommittees. Lastly, the activity phase was initiated in 2010. The Landscape Heritage Inventory Composition Committee was established in the year and has been active since then, conducting researches on landscape heritage in Japan and publishing the results. The local branches of the Japanese Institute of Landscape Architecture seized the initiative when the researches were conducted, and it systematically performed the activities. Between 2001 and 2006, the preparatory phase, a variety of case studies were performed to deal with modern landscape heritage from various perspectives such as academic, legal and institutional perspectives. Consequently, the concept of modern landscape heritage conservation was expanded to the concept of landscape heritage in terms of conservation activities. This shed new light on the role of landscape architecture in the society and led to a deeper consideration on the fundamentals of landscape architecture. The fact that the Japanese Institute of Landscape Architecture delivered academic messages and secured the sustainability through documentation and publication of the results of the activities without external financial support has a critical implication for us.

박진욱,유용호,김양균,박병직,김휘성 사단법인 한국터널지하공간학회 2019 한국터널지하공간학회논문집 Vol.21 No.6

인구 초과밀화 현상이 심해지고 있는 국내 수도권 및 대도시에서 발생되고 있는 교통문제 해결을 위해 지하도로 개발 사업이 늘어나고 있으며, 시공성과 경제성의 이점을 가지는 복층터널 기술을 적용하여 다수의 지하도로를 계획하고 있는 추세이다. 복층터널은 하나의 굴착단면을 두 개로 나눠 상하행선으로 사용하는 방식으로 대부분 층고가 낮아 소형차량 전용도로로 사용되고 있는 실정이다. 또한, 이러한 소단면 특성으로 인해 환기 및 방재 측면에서도 일반 도로터널과 상이한 특성을 가지게 된다. 본 연구에서는 복층터널과 같이 층고가 낮은 소단면 터널에 반횡류식 환기방식의 하나인 대배기구 방식을 적용한 운영안을 제시하고 FDS 시뮬레이션을 통해 화재발생 위치와 대배기구 배연 방식 등에 따른 배연 특성을 비교하여 분석하였다. 그 결과 균일배기와 달리 대배기구를 이용하여 집중배연시 연기의 확산지연 효과가 최대화 되고 연기가 화재지점 상하류 50 m안에 제한시킬 수 있었다. Recently, the number of underground road development projects has been increasing to solve traffic problems in the national capital region and metropolitan areas with intensified overcrowding, and there has been a tendency to plan underground roads by applying a double-deck tunnel technology that has advantages in constructability and economical efficiency. The double-deck tunnel has a structure where one excavation section is divided into two parts and used as up and down lines, and is mainly used as a road for small vehicles only due to its low floor height. In addition, due to the small cross-sectional area, it has characteristics different from those of general road tunnels in terms of ventilation and disaster prevention. In this regard, this study proposed an operational plan that applies an oversized exhaust system, which is one of semi-transverse ventilation systems, to small cross-sectional tunnels like double-deck tunnel with low floor height, and a comparative analysis between smoke exhaust characteristics according to the fire occurrence locations and oversized exhaust systems was conducted using the Fire Dynamics Simulator (FDS). The results showed that unlike uniform exhaust, intensive smoke exhaust using the oversized exhaust port maximized the delay effect of smoke diffusion and limited the smoke within 50 m above and below the fire point.

Analysis on the Natural Landscape Conservation Policies of Kyoto, Japan

박진욱,김규섭,김재웅 한국전통조경학회 2016 한국전통조경학회지 Vol.14 No.-

This paper provides a chronological analysis on the natural landscape conservation policies of Kyoto, a representative historic city of Japan. The result is as follows. First of all, the Kyoto city government has executed city planning based on Scenic Landscape Districts since the early 1900s, and multiple special preservation districts showing the identity of Kyoto have been designated and preserved under the Ancient Capital Cities Preservation Laws against city sprawl. Also the Kyoto city government has preserved the natural landscape in the mountainous/piedmont area that is regarded as relatively hard to be damaged by development projects through expanding Scenic Landscape Districts and establishing city ordinances. Secondly, several natural landscape conservation policies have been promoted as part of the entire city planning, not as separated independent policies. The Kyoto city government has executed the relevant policies, considering the coherence between the landscape planning as part of city planning and the other independent landscape planning projects. Lastly, the Kyoto city government has dealt with various difficulties that cannot be dealt with the national laws by establishing independent city ordinances. The landscape policies formed recently consist of several ways of management operation, such as landscape preservation through regulations and citizen's participation. Especially, promoting citizen's participation is considered as an exceedingly effective way to execute the landscape policies more effectively because the citizen's participation tends to increase their interest in landscape.

High-performance Hg²⁺ FET-type sensors based on reduced graphene oxide/polyfuran nanohybrids

박진욱,장정식 한국공업화학회 2014 한국공업화학회 연구논문 초록집 Vol.2014 No.1

A new type of field-effect transistor (FET) sensor, based on reduced graphene oxide (rGO)-polyfuran (PF) nanohybrids, was strategically developed. The liquid-ion gated FET based on the rGO/PF nanohybrids showed p-type behavior, which means the hole transporting behaviour. The sensing transducer exhibited a rapid response (<1 s) and high sensitivity (10 pM) in a liquid-ion-gated FET-type Hg²⁺ sensor. Excellent Hg²⁺ discrimination in heavy metal mixtures was also monitored in real time.

지역 주민 주체의 농촌지역 경관관리 사례 연구

박진욱,이유직 한국농촌계획학회 2017 농촌계획 Vol.23 No.1

Four requirements for the operating and supporting system for sustainable landscape management will be discussed through this paper. The requirements are based on multiple case studies on the structure and the process of development of three organizations that have been contributing to the sustainable rural landscape management in Japan since 1989. The first requirement is that the residents should recognize regional problems and voluntarily organize a group which can properly deal with the problems. Secondly, members of the organization should have a solid grasp of the goal of their activities (or founding principal of the organization) and share it among themselves. Founding principal should include the history of natural circulation system in the area, cultural features and a future plan in association with human resources. Thirdly, the administration of the organization should be separated from the founder, the residents. The administration, such as business promotion, becomes more effective when consigned to a separate entity, not to the residents. Lastly, the interaction among separate entities is crucial to promote diverse activities for the local landscape management. The administrators and experts need to cooperate to draw a precise conclusion regarding the way of interaction. These requirements drawn from the Japanese case studies should be localized to the Korean circumstances for further adoption.

복층터널내 화재특성에 대한 실험적 연구

박진욱,유용호,김휘성,박병직 한국화재소방학회 2016 한국화재소방학회논문지 Vol.30 No.2

In the wake of expanding and overpopulating urban areas, traffic congestion has been worsening increasingly, causinghuge economic losses. In a bid to effectively use the space of metropolitan areas, the construction and operation of a doubledeck tunnel has been on the rise. On the other hand, a lower height of a double deck tunnel is expected to generatemore smoke and soot in a fire than other usual tunnels. Therefore, it is undesirable to apply the standard for fire intensityor smoke generation, which were designed for existing road tunnels. A part of an effort to propose a design fire curve thatis useful for double deck tunnel, is intended to obtain and analyze the fire characteristics in a double deck tunnel through areal scale fire test. The test was conducted according to the fire scenario with one passenger car and two passenger cars;the monitored fire intensity was a maximum of 2.4 MW and 3.5 MW, respectively. 최근 도시의 거대화 및 과밀화의 영향으로 교통정체가 심해지고, 이로 인한 경제적 손실이 막대하게 증가하고 있는 실정이다. 따라서 대도시 공간의 효율적인 활용 방안으로 현재 국내외 도심지 터널이 복층터널로 계획되고 운영되는 추세이다. 그러나 복층터널의 경우 층고의 감소로 인해 터널 내부에서의 차량 화재시 일반 도로터널에 비해 더 많은 양의연기 및 검탱이 발생될 것으로 예측되기 때문에 기존의 일반 도로터널을 대상으로 구축된 설계화재강도나 연기발생량을적용하여 설계하고 운영하는 것은 바람직하지 않다. 따라서 본 연구에서는 복층터널 설계시 유용한 설계화재곡선 제시를위한 연구의 일환으로 실규모 차량화재실험을 수행하여 복층터널내 화재 특성 데이터를 획득하고 분석하였다. 실험은 승용차 1대의 화재상황과 2대의 화재상황, 두 가지 상황을 구현하여 수행하였으며, 실험 결과로부터 화재강도는 승용차 1대에서는 최대 2.4MW, 승용차 2대에서는 최대 3.5MW가 나타났다.

협대역 고출력 전자기파로 인한 CMOS IC에서의 오동작 특성 연구

박진욱,허창수,서창수,이성우,Park, Jin-Wook,Huh, Chang-Su,Seo, Chang-Su,Lee, Sung-Woo 한국전기전자재료학회 2016 전기전자재료학회논문지 Vol.29 No.9

This study examined the malfunction mode of the HCMOS IC under narrow-band high-power electromagnetic wave. Magnetron is used to a narrow-band electromagnetic source. MFR (malfunction failure rate) was measured to investigate the HCMOS IC. In addition, we measured the resistance between specific pins of ICs, which are exposed and not exposed to the electromagnetic wave, respectively. As a test result of measurement, malfunction mode is shown in three steps. Flicker mode causing a flicker in LED connected to output pin of IC is dominant in more than 7.96 kV/m electric field. Self-reset mode causing a voltage drop to the input and output of IC during electromagnetic wave radiation is dominant in more than 9.1 kV/m electric field. Power-reset mode making a IC remained malfunction after electromagnetic radiation is dominant in more than 20.89 kV/m. As a measurement result of pin-to-pin resistance of IC, the differences between IC exposed to electromagnetic wave and normal IC were minor. However, the five in two hundred IC show a relatively low resistance. This is considered to be the result of the breakdown of pn junction when latch-up in CMOS occurred. Based on the results, the susceptibility of HCMOS IC can be applied to a basic database to IC protection and impact analysis of narrow-band high-power electromagnetic waves.
