국제에너지기구 풍력분과 57차 집행위원회 국제공동과제 현황
정진화(Chung, Chin-Wha),천석현(Chun, Suk-Hyun) 한국신재생에너지학회 2006 한국신재생에너지학회 학술대회논문집 Vol.2006 No.06
The IEA Wind agreement for co-operation in the R&D of wind energy system was founded in 1974. The Korea has been a contracting party to the IEA wind energy program since 2003. The contracting parties are designated by the 20 member countries and the EC. IEA Wind agreement is for member countries to exchange information, knowledge and to organize international collaboration on R&D projects called Taskes and Annexes. The Executive Committee approves and controls the R&D Tasks, and its meetings are held twice a year. This paper describes the status of current 7 implementing Tasks that were reported to the recent 57th Executive Committee meeting this year in Brussels, Belgium.

The core of space perception in 'La phenomenologie de la perception' written by Maurice Merleau-Ponty is that in modern architecture mechanical and passive to space experience, phenomenological elements such as up/down, depth, time, exercise, place, etc rather than body itself are newly recognized in overall consideration of physical responses. This means that our body can also experience our surrounding space at one with space beyond one object. In this context, modern architect Tadao Ando induced people to experience space through architectural languages such as undefined crack area, conscious contact, abstract nature, etc. Such architectural languages are materialized in combination of space elements such as light, water, nature, wall, materials and property of matter, slope and staircase, and one architectural space is formed through interaction of accidental events between each element of building and human movement. Although it is invisible, phenomenological characteristics shown through human body can be applied in the same way to the architectural space. Therefore, you will be able to newly recognize space concept if you study on architectural space with phenomenological characteristics manifested.
Ordination에 의한 대아댐 주변 산림 식생 분석
정진철 ( Jin Chul Chung ),장규관 ( Kyu Kwan Jang ) 한국산림과학회 2003 한국산림과학회지 Vol.92 No.1
In order to determine ecological niches of forests around Daea Dam, the studies were analyzed on the methods of TWINSPAN and CCA ordination. The results are summarized as follows: Four groups were determined by TWINSPAN ; Quercus dentata, Quercus variabilis, Quercus aliena and Zelkova serrata community. In the relations of community and environmental factors, Quercus dentata and Quercus variabilis community was distributed in the high elevation and low nutrition . Quercus aliena community was distributed in the high percentage of nutrition and in the low elevation . Zeliova serrata community was distributed in the height percentage of nutrition and in the from medium to low elevation. In the relations of major species and environmental factors, Quercus mongolica, Quercus dentata, Fraxinus sieboldiana, Lindera obtusiloba, Diospyros lotus, Rhododendron schlippenbachii, Sorbus alnifolia and Rhus trichacarpa were distributed in the high elevation and low nutrition. Zelkova serrata, Corylus heterophylla var, thunbergii, Fraxinus mandshurica, Celtis sinensis, Acer pseudosibolianum, Actinidia polygama and Acer mono were distributed in the high percentage of pH, Mg^++, C.E.C and CA^++ and in the low elevation. Tripterygium regelii and Ampelopsis brevipedunculata var, heterophylla were distributed in the high percentage of P^2O^5. Picrasma quassioides, Maackia amurensis, Ulmus pumila, Euonymus sachalinensis Albizzia julibrissin, Quercus aliena, Morus bombycis and Staphylea bumalda were distributed in the high percentage of Na and in the low elevation.
〈기술논문〉 PAV(Personal Air Vehicle) 개발에 필요한 주요 성능 지표들
정진덕(Chung Jindeog),강왕구(Kang Wanggu) 대한기계학회 2010 대한기계학회 춘추학술대회 Vol.2010 No.5
To resolve the current ground traffics congestion PAV(Personal Air Vehicle) is suggested one of the means of future transportation. Various configuration and concept of PAV's are being introduced and couple of PAV's are under flight test. The configuration and aerodynamic characterisitcs, type of propulsion system, structure, control, system requirements of the suggested PAVs are summarized in this paper. And key performance parameters for PAV development considering future technology enhancement are suggested.
주류소비가 사망률과 범죄율에 미치는 효과분석: 주요 손상사고와 강력범죄를 중심으로
정진화 ( Jin Hwa Chung ),주하연 ( Hailey Hayeon Joo ) 한국응용경제학회 2013 응용경제 Vol.15 No.1
본 논문은 1994-2010년까지의 패널자료를 이용하여 음주남용이 사망률 및 범죄율에 미치는 영향을 실증 분석하였다. 특히 일인당 알코올 소비량과 사망률 및 범죄율 간에 예상되는 내생성 문제를 해소하기 위해 도구변수를 도입하였다. 여러 해외 연구들이 제시한 바와 같이 한국의 경우도 일인당 알코올 소비량과 사망률 및 범죄율 사이에 뚜렷한 양(+)의 인과관계가 식별되었다. 특히 일인당 알코올 소비량의 증가는 자살, 타살, 추락사 등 손상사고에 의한 사망률을 증가 시키며, 살인과 강간 등 강력범죄의 발생을 촉진시키는 효과가 있는 것으로 분 석되었다. 본 논문은 그동안 국내에서 검토되지 않았던 음주소비량과 사망률, 그리고 범죄율 사이의 인과관계를 계량경제학 방법론을 이용하여 분석했다는 점에서 의의를 갖는다. 또한 미국 중심으로 축적되어 있는 실증연구들과 국내의 결과를 비교할 수 있는 기회를 제공한다. This paper investigates how alcohol consumption influences both mortality and crime rates, exploiting the Korean panel data set from 1994 to 2010 in 4 metropolitan areas and 8 regional states. In particular, the instrumental variables are used for both analyses, to solve the potential endogeneity problem in alcohol consumption and mortalities as well as crimes. According to the estimation results, as per-capita alcohol consumption increases, both total mortality and total crime rates increase. Moreover, the increase of per-capita alcohol consumption affects the suicide, homicide, and falling-death rates, while that affects the murder and rape rates. The main contribution of this research is about identifying and confirming that the increase in alcohol consumption can be effective to raise externality costs in Korea.
2000년대 이후 수원교구 성당 전례공간의 구성방식에 관한 연구
정진원(Chung, Jin-Won),홍승택(Hong, Seong-Teak) 대한건축학회 2012 대한건축학회논문집 Vol.28 No.12
The Suwon Diocese is the most important place in the 200 years of Korean Catholic history with its fourteen sacred places. It has the second largest number of believers in the country in its seventeen cities and two districts, and is still growing followed by a development of new towns such as Gwanggyo and Jukjeon. Liturgical space is a core place where divine services are executed and thus symbolizes identity of the church. In this study, we examined the configuration of the liturgical space to illuminate the contemporary trend of church planning in Korea. For this, we analysed its spatial components, i.e. sanctuary, altar, tabernacle, vestry, nave, church nursery, choir, confessionals and hall. The statistical findings are then compared with design manual of the Suwon Diocese in order to suggest a proper direction for the construction in the future. The evaluated at the end that as the standardized sequence of the liturgical ceremony demands a specific adjacency of the spatial components, the modern churches in Suwon Diocese still maintains the old spatial connections. Unlike the classical church plan, however, the contemporary church plans become more sub-divided to render the interior space more complex and become bigger to make the building more rectangular.
