蓄熱지붕의 冬節期 熱性能에 關한 硏究

朴碩鉉 충주대 2004 産業科學論文集 Vol.12 No.-

This thesis discusses the modeling of the thermal roof with the air circulation system and an experimental study of the heat capacity of thermal storage roof with slab construction. In this system, the fully glazed absorber plate is put on the top of the conventional pitch roof made of massive concrete and acts as a solar air heater. Solar radiation collected into absorber is stored in the roof structure by radiation and convection so that it reduces the nighttime heating load through the roof. Another part of the energy is also transmitted to internal air drawn into the channel and is then introduced into the room. The energy balance equations to this system are solved using a finite difference method and the calculation results show a good agreement with the measured ones obtained from experiments. From the results, it is seen that the thermal storage roof with the air circulation system reduces the heat loss significantly compared with that for the conventional roof and has the instantaneous solar collection efficiency of about 25%.

This paper reports on a theoretical and an experimental study of the heat capacity of thermal storage roof with slab construction. In this system, the fully glazed absorber plate is put on the top of the conventional pitch roof made of massive concrete and acts as a solar air heater. Solar radiation collected into absorber is stored in the roof structure by radiation and convection so that it reduces the nighttime heating load through the roof. Another part of the energy is also transmitted to internal air drawn into the channel and is then introduced into the room. The energy balance equations to this system are solved using a finite difference method and the calculation results show a good agreement with the measured ones obtained from our experiments. From the results, it is seen that the thermal storage roof with the air circulation system reduces the heat loss significantly compared with that for the conventional roof in winter season.

Q-NAV: 수중 무선 네트워크에서 강화학습 기반의 NAV 설정 방법

박석현,조오현 중소기업융합학회 2020 융합정보논문지 Vol.10 No.6

수중 자원 탐색 및 해양 탐사, 환경 조사 등 수중 통신에 대한 수요가 급격하게 증가하고 있다. 하지만 수중 무선 통신을 사용하기 앞서 많은 문제점을 가지고 있다. 특히 수중 무선 네트워크에서 환경적 요인으로 인해 불가피하게 발생하는 불필요한 지연 시간과 노드 거리에 따른 공간적 불평등 문제가 존재한다. 본 논문은 이러한 문제를 해결하기 위해 ALOHA-Q를 기반으로 한 새로운 NAV 설정 방법을 제안한다. 제안 방법은 NAV 값을 랜덤하게 사용하고 통신 성공, 실패 유무에 따라 보상을 측정한다. 이후 보상 값에 따라 NAV 값을 설정 한다. 수중 무선 네트워크에서 에너지와 컴퓨팅 자원을 최대한 낮게 사용하면서 NAV 값을 강화 학습을 통하여 학습하고 한다. 시뮬레이션 결과 NAV 값이 해당 환경에 적응하고 최선의 값을 선택하여 불필요한 지연 시간문제와 공간적 불평등 문제를 해결할 수 있음을 보여준다. 시뮬레이션 결과 설정한 환경 내에서 기존 NAV 설정 시간 대비 약 17.5%의 시간을 감소하는 것을 보여준다. The demand on the underwater communications is extremely increasing in searching for underwater resources, marine expedition, or environmental researches, yet there are many problems with the wireless communications because of the characteristics of the underwater environments. Especially, with the underwater wireless networks, there happen inevitable delay time and spacial inequality due to the distances between the nodes. To solve these problems, this paper suggests a new solution based on ALOHA-Q. The suggested method use random NAV value. and Environments take reward through communications success or fail. After then, The environments setting NAV value from reward. This model minimizes usage of energy and computing resources under the underwater wireless networks, and learns and setting NAV values through intense learning. The results of the simulations show that NAV values can be environmentally adopted and select best value to the circumstances, so the problems which are unnecessary delay times and spacial inequality can be solved. Result of simulations, NAV time decreasing 17.5% compared with original NAV.

박석현 忠州大學校 2012 한국교통대학교 논문집 Vol.47 No.-

Architectural characteristics deriving from climate, features, and culture of a region are expressed in traditional residential buildings. These buildings mostly accommodate with nature, and accept architecture and people as a part of natural ecology. Our ancestors made most out of a given environment, sometimes blocking deteriorating elements, and other times actively adopting nature into a house. For this study, traditional housing architecture that contains old wisdom will be analyzed. The study that 1) derives ecological elements from traditional housing architecture 2) analyzes individual style of each house and examines general orders expressed in traditional houses in Chung-buk province 3) analyzes case studies to find ecological elements in traditional houses in Chung-buk province, will explores ecological methods and orders that are reflected in traditional housing architecture. Ecological elements of traditional houses in Chung-buk province was analyzed on a micro scale, but this can be applied to other regions; by applying excellent ecological elements of traditional houses to modern architecture, quality of life could improve. This study is expected to contribute to the development of ecological architecture that receives much attention these days. Also, follow-up studies are called for to complement insufficient aspects such as practical application to modern architecture.

朴碩鉉 忠州大學校 1985 한국교통대학교 논문집 Vol.18 No.2

Nowadays our dwelling environments are improving in nearly every respect. However the acoustic environment seems to be one exception to this general trend in spite of its theoretical and technical development, due to the noises from the increasing number of automobiles outside and the household electric goods indoors. In designing urban residential buildings, the problem of noise became an important environmental design constraint. This study reviews the current noise performance standards in foreign countries and korea with particular reference to residential buildings. Some design strategies for noise control have been discussed with a view to improving the environmental quality of urban residential areas.
