<남향집>은 1930년대에 한국의 자연에 바탕을 둔 한국적 인상주의의 완성한 오지호의 대표작이다. 그리고 <남향집>은 오지호가 1935년부터 1944년까지 거주했던 개성 초당집의 사랑채와 앞뜰의 대추나무를 그린 작품으로 등록문화재로 지정되어 있다. 본 연구는 <남향집>이 1947년경 제작되고 1960년대 후반에 제작되거나 보필되었다는 연구에 관해 반론을 제시하였다. 각종 문헌과 아카이브 자료, 보고서를 근거로 <남향집>이 1939년 빛을 바탕으로 한국인의 정서를 담아 그린 근대미술작품임을 증명하였다. 또한 1948년 오지호 개인전에 사양(斜陽, 25호)으로 출품된 <남향집>에 관한 오지호의 작품 설명을 분석하여 작품을 제작한 계절과 시간, 작품 속 소녀에 관해 밝혀보았다. 이러한 연구를 통해 <남향집>이 1947년경 제작되고 1960년대 후반 재제작되었다는 주장에 대한 반증으로 작품에 대한 사실을 밝혀 보고자 하였다. 먼저 <남향집>이 일제강점기 개성 초당집 사진의 구도, 기물 등과 일치하지 않다는 주장에 관해 개성집 초당집 사진과 <남향집> 작품을 유족의 증언을 토대로 비교․분석하여 일치함을 증명하였다. 그리고 <남향집>의 소재가 전남 화순 동복의 오지호집이라는 주장에 대해 오지호 동복집은 기와집으로 기와집을 초가집으로 바꾸어 <남향집>을 그릴 수 없다는 근거를 제시하였다. 보존상태가 양호하여 해방 후 재제작 되었다거나 앞, 뒷면이 달라 보필하였다는 주장에 대해 1948년 오지호 개인전을 도운 김은수의 회상의 글을 근거로 당시 개성시기 현존하는 작품이 완벽한 상태였으며 1955년 오지호가 목조로 지은 작품 친화적인 오지호 화실을 통해 반증하였다. 그리고 국립현대미술관에서 2008년 오지호 작품 27점을 과학적 분석한 자료를 토대로 해방 후에 오지호가 작품을 덧칠하거나 재제작 했을 가능성이 희박함을 밝혔다. 본 연구의 <남향집>의 제작시기, 재료분석, 작품분석을 통해 한국적 인상주의를 완성한 오지호와 <남향집>에 관해 정당한 평가를 받을 수 있을 것이다. South Facing House is considered a seminal work by Oh Ji-ho who works in a kind of Korean-style Impressionism based on Korean nature. This painting features Sarangchae, a detached building of a residence used as a reception room for male guests, and a jujube tree in Chodangjip in Gaeseong where Oh resided from 1935 to 1944. This residence has been designated as a registered cultural property. This study raises an objection to an assertion that South Facing House was painted and complemented in 1947 or in the late 1960s. This study has verified that this work is a modern artwork painted in 1939 on the basis of literature, archived materials, and survey reports. It has also tried to elucidate the season and time of this painting and the girl appearing in this work based on the description of South Facing House that was on show at Oh’s 1948 solo exhibition under the title The Declining Sun. This has also verified the assertion that this work was not painted after Korea’s liberation from Japanese colonial rule. First of all, it has been proved that the setting of furniture and house hold items in South Facing House matches up with that of the photograph featuring Chodangjip through a comparative analysis on the basis of the bereaved family’s testimony. As to the assertion that South Facing House is a depiction of Oh’s house in Dongbok, Hwasoon, Jeonnam, this study provides evidence that the that thatched-roof house in South Facing House could not have been painted from the roof-tiled house in Dongbok. It has also proved its opposition against the assertion that this work was produced after liberation in consideration of its preservation and material, based on an essay by Kim Eun-soo who assisted at Oh’s 1948 solo exhibition. This study has revealed that the possibility of this work being repainted or reproduced by Oh after liberation is extremely low based on the materials of 27 pieces which the National Museum of Modern and Contemporary Art, Korea scientifically analyzed. A reasonable evaluation of Oh Ji-ho s Korean-style impressionism and his work South Facing House can be made through an analysis of the production period and materials.

Combustion characteristics of gaseous inverse O₂/H₂ coaxial jet flames in a single-element model combustor

Kim, Tae Young,Choi, Sun,Kim, Young Hoo,Ahn, Yeong Jong,Kim, Hee Kyung,Kwon, Oh Chae Elsevier 2018 ENERGY Vol.155 No.-

<P><B>Abstract</B></P> <P>To effectively design hydrogen (H<SUB>2</SUB>)/oxygen (O<SUB>2</SUB>) liquid rocket engines through understanding the combustion characteristics of H<SUB>2</SUB>/O<SUB>2</SUB> bipropellants, fundamental studies for the bipropellants in different phases are needed. This study is focused on the combustion characteristics of inverse gaseous O<SUB>2</SUB>/H<SUB>2</SUB> coaxial jet flames in a single-element model combustor as a preliminary step for succeeding studies of injection at different phases in the combustor, visualizing flame structure by direct imaging, OH<SUP>∗</SUP> chemiluminescence and OH planar laser-induced fluorescence. With increasing Reynolds number (Re), the frequency of occurrence of the local flame extinction increases and the length of the disconnected OH reaction zone is extended. The OH layer thickness increases downstream, while it is almost constant where the local flame extinction occurs and decreases with increasing Re due to the enhanced strain and scalar-dissipation rates. The excessive flame wrinkledness increases the local flame strain rate and results in the local flame extinction, exhibiting the tendency of increasing and then decreasing flame surface density with increasing Re. The probability density function of OH intensity quantifies the fluctuation intensity of OH radicals and the possibility of the local flame extinction.

Kang, S.H.,Oh, I.Y.,Heo, J.,Lee, H.,Kim, J.,Lim, W.H.,Cho, Y.,Choi, E.K.,Yi, S.M.,Sang, D.S.,Kim, H.,Youn, T.J.,Chae, I.H.,Oh, S. Elsevier/North-Holland Biomedical Press 2016 INTERNATIONAL JOURNAL OF CARDIOLOGY Vol.221 No.-

<P>Objective: Cardiac arrest is one of the common presentations of cardiovascular disorders and a leading cause of death. There are limited data on the relationship between out-of-hospital cardiac arrest (OHCA) and ambient temperatures, specifically extreme heat. This study investigated how heat and heat waves affect the occurrence of OHCA. Methods: Seven major cities in Korea with more than 1 million residents were included in this study. A heat wave was defined as a daily mean temperature above the 98th percentile of the yearly distribution for at least two consecutive days. Results: A total of 50,318 OHCAs of presumed cardiac origin were identified from the nationwide emergency medical service database between 2006 and 2013. Ambient temperature and OHCA had a J-shaped relationship with a trough at 28 degrees C. Heat waves were shown to be associated with a 14-% increase in the risk of OHCA. Adverse effects were apparent from the beginning of each heat wave period and slightly increased during its continuation. Excess OHCA events during heat waves occurred between 3 PM and 5 PM. Subgroup analysis showed that those 65 years or older were significantly more susceptible to heat waves. Conclusions: Ambient temperature and OHCA had a J-shaped relationship. The risk of OHCA was significantly increased with heat waves. Excess OHCA events primarily occurred during the afternoon when the temperature was high. We found that the elderly were more susceptible to the deleterious effects of heat waves. (C) 2016 Elsevier Ireland Ltd. All rights reserved.</P>

요구원 후기시의 탈원근법적 주체와 시각의 형이상학

오연경(Oh, Youn-kyung) 한국시학회 2013 한국시학연구 Vol.- No.36

The Kyuwon Oh’s later poems, so called a ‘raw image poetry’ are based on a new alternative visual regime as a challenge to the anthropocentric perspective regime. The post-anthropocentricism of Kyuwon Oh’s poems proceeds from a denial of signifying or naming subject and such a subject-centered language. So the raw image poetry cannot but make into question not only a notion sticked to a language but also a notion sticked to a view. In this question, the main issue is a perspective hypothesis which establish a basis of subjectivity and rationality in anthropocentricism. Thus the raw image suggested by Kyuwon Oh is not a phenomenon of things in the raw, but an alternative hypothesis, that is a language of post-perspective vision against the conventionalized hypothesis sticked to things, This paper examines in reference to the post-perspective vision, the methodology of the raw image poetry which aims to make a language in contact to phenomenon of things by an innovation of perception. Therefore this paper would demonstrate that the keys to methodology of the raw image poetry are the post-perspective vision by analyzing in detail three points of writing poetry, ⑴ to make an another visual notion by eliminating a perspective depth, ⑵ to rearrange a routine visibility by reversing the principles of forms and backgrounds, ⑶ to create a metaphysical vision by realizing a frame-internal subject. It brings us a new ability of vision to see the things which are assigned to the invisible. The new ability of vision provides a ‘metaphysics of vision’ which visualizes a metaphysical longing for infinities of the world. The metaphysics of vision is considered as a kind of artistic utopia to overcome a problematic modernity in the society of fetishism. The raw image poetics of Kyuwon Oh can be appreciated in terms of a denial of perspective regime which establish a basis of subjectivity and rationality and a creation of metaphysical vision as counterplans for the perspective regime.

It is shown that the effect of variable parameters on flame structures and NOx emissions in the laminar<br/> partially premixed methane-air flames with a co-axial Bunsen burner. Objectives of this paper is to<br/> understand the effects of flow variables on NOx emissions and the flame structure with OH<br/> chemiluminescence, including reconstructed image by abel inversion processing at each conditions. A fuel<br/> flowrate of 200 [cc/min] was fixed and the amount of air was varied from 400 to 1200 [cc/min]. The<br/> experimental variables were equivalence ratio( ), fuel split percentage( ) and inner tube recess(x/D). Flow<br/> conditions were ranged from 1.36~4.76(equivalence ratio), 50~100(fuel split percentage) and 0~20(inner<br/> tube recess). NOx analyzer and ICCD camera with a OH filter were used as a main experimental<br/> apparatus. In addition, Abel inversion, which is a kind of tomography and valuable to estimate a<br/> two-dimensional structure of co-axial flames from cubical information, was employed for combustion<br/> diagnostics. Results from this study indicate that the main effects depend on equivalence ratio and next<br/> sigma, x/D for NOx production and OH formation. Throughout Abel inversion, we could affirm the<br/> maximum position and the tendency of OH radical intensity by variants at five axial heights above the<br/> burner exit.

기우제의(祈雨祭儀)를 통해 본 영남 지방관의 일상과 대민의식

Through this article, I investigated how Youngnam reeves performed ritual for rain as a official business. To do this I focused on the rituals of Chaewon Oh Hoing-Mook (1834~?), who was reeve of Youngnam province. Oh`s ritual was official, but dynamic and flexible. In a aspect Oh`s ritual for rain was one of his routine jobs. In other aspect, through his ritual, Oh tried to establish social integration with consideration for the subjects. The ritual for rain was performed when drought kept going on. In this natural crisis. he held the ceremony to meet the subjects face by face. Through two additional ritual, especially, he preserved social order, and took care of the subjects preferentially. All social class people can also meet each other in the ritual. Performing the ritual with highly established form, he also gave great concern to the subjects. He gained sympathy of the subjects`s pain, and paid fruits or money. He also minimized the subjects`s burden loaded to them. In these his routine rituals, I can know that reeves shared their joy with the subjects and communicated each other. It is fundamental procedure to choose ritual place, to prepare things needed in the ceremony, and to write a ritual oration in the official ritual. It is common to prepare ritual place, things needed in ritual, and order of ritual according to law books. The ritual was based on Conficianism, therefore taboos or belief system of official ceremony was less restricted than those of private ceremony. One of remarkable thing is ritual oration. After 13th ritual, the two additional rituals was executed. In those rituals, the formality of orations were less strict than that of previous 13 rituals. He showed his wish for raining with the ritual oration, which had long sentences and flexible contents. Reeves usually understood the Mother Nature in aspect of Confucianism. Eventually, reeves recognized the relationship between God and human as a reciprocal interaction.

Physical properties of waterborne soft feel coatings for instrument panel were investigated. Soft feel coatings give warm and velvet touch for cold and hard plastic materials. Waterborne soft feel coating is composed with two parts. Part A contains polyester polyurethane dispersion (PE-PUD), OH-functional water dispersible polyurethane resin (PC-PUD) and OH-functional water dispersible alkyd resin (OH-PA). Part B contains hydrophilic hexamethylene diisocyanate trimer (HHDI). Soft feeling of coated panel was related with the amounts of PC-PUD and OH-PA. The physical properties of coated panel could be controlled by the NCO/OH ratio from Part A and Part B. Soft feeling was enhanced with relevant to PE-PUD content but the content of PE-PUD was limited because of weakening of coated film strength. For excellent touch and good property, the optimum composition of soft feel coat was PC-PUD(30%) and PE-PUD(20%). The results from all reliability tests satisfied soft feeling, scratch, chemical resistance and fogging.

Equatorial-Skew형[Co(TRDTRA)(OH₂)]착물과 ??,?? 그리고 ?? 이온 간의 치환반응결과 생성된 차물의 치환반응성 및 구조를 전자흡수 스펙트럼과 Yamatera 이론에 따라 조사하였다. 속도론적 자료로부터 착물과 ??,?? 그리고 ?? 이온의 반응차수는 각각 1차이며 총괄 반응차수는 2차임을 알 수 있었다. ?? 및 ?? 이온에서 생성된 착물의 구조는 이성질화 반응이 동반된 Polar-Chair 형이며, ?? 이온의 경우에는 이성질화 반응이 동반되지 않은 Equatorial-Skew 형임을 알 수 있었다. The substitution reaction and structrue of products obtained from the reaction of Equatorial-Skew-[Co(TRDTRA)(OH??)](TRDTRA=trimethylenediaminetriacetate) with ??,??, and NCS ions have been investigated by means of electronic absorption spectroscopy and theoretical calculation based on the Yamatera`s theory. According to kinetic data, the substitution reaction order for the complexes such as ??,?? and ?? was the first order, respectively, and overall reaction order was second order. It has been determined that the structure of products having ?? and ?? ions was Polar-Chair type complexes which were accompanying with isomerization and having ?? ion was Equatorial-Skew type complex which was not accompanying with isomerization.

수용액 및 물-유기용매 혼합용매에서의 Hg$^{2+}$ 에 의한 Co(Ⅲ) 착물의 수화반응

오창언,윤두천,도명기,Oh Chang Eon,Yoon Doo Cheon,Doh Myung Ki 대한화학회 1990 대한화학회지 Vol.34 No.5

Observed rate constants (k$_{obs.}$) for Hg$^{2+}$-catalysed aquation of cis-[Co(en)$_2$(OH$_2$)Cl]$^{2+}$, [Co(NH$_3$)$_5$Cl]$^{2+}$, cis-[Co(NH$_3$)$_4$(OH$_2$)Cl]$^{2+}$, and [Co(NH$_2$CH$_3$)$_5$Cl]$^{2+}$ were measured at various concentrations of Hg$^{2+}$. The k$_{obs.}$ was increased with increasing the concentrations of Hg$^{2+}$. The k$_{obs.}$ were related to mechanistically derived rate constants by the relationship; Rate = k$_2$K[complex][Hg$^{2+}$]. Various mixed aqueous-organic solvent have been successfully employed for Hg$^{2+}$-catalysed aquation of octahedral myetal complexes. From the slope of the plot of log k againt Y (solvent ionizing power), the mechanism on the aquation of Co(Ⅲ) complexes by Hg$^{2+}$ has been suggested to be I$_d$-mechanism. The change in a rate on aquation of each Co(Ⅲ) complex was related to the ligand field parameters (${\Delta}$), for Co(Ⅲ) complexes. 촉매로서 Hg$^{2+}$을 사용한 수화반응에서 cis-[Co(en)$_2$(OH$_2$)Cl]$^{2+}$, [Co(NH$_3$)$_5$Cl]$^{2+}$, cis-[Co(NH$_3$)$_4$(OH$_2$)Cl]$^{2+}$ 및 [Co(NH$_2$CH$_3$)$_5$Cl]$^{2+}$착물들은 Hg$^{2+}$의 농도가 증가할수록 관측속도상수(k$_{obs}$)의 값이 증가하였다. Hg$^{2+}$에 의한 수화반응의 속도법칙은 Rate = k$_2$K[complex][Hg$^{2+}$]이었고, 그 메카니즘이 연구되었다. 또한 여러가지 유기용매-물 혼합용매에서 Co(Ⅲ)착물의 Hg$^{2+}$에 의한 수화반응이 연구되었다. 용매의 성질인 Y (solvent ionizing power)값에 대한 log k를 도시하여 그 기울기인 m값을 얻었다. 그 m값으로부터 수화반응의 메카니즘을 추정하였다. 속도론적인 자료로부터 Hg$^{2+}$에 의한 Co(Ⅲ)착물의 수화반응이 I$_{d^-}$메카니즘으로 제안되었다. 각 Co(Ⅲ)착물의 속도의 차이는 여러가지 리간드가 배위된 Co(Ⅲ)착물의 리간드장파라메타(${\Delta}$)값과 관계가 있었다.
