西州 曺夏望의 삶과 시세계에 관한 일고찰

이승용(Lee Seung yong) 대동한문학회 2017 大東漢文學 Vol.51 No.-

曺夏望(1682~1747)은 조선후기 少論에 속하는 인물로, 본관은 昌寧, 자는 雅仲, 호는 西州이다. 老·少論간의 黨爭이 가장 치열했던 景宗과 英祖시기에 관직에 진출하였지만, 당쟁에는 크게 관여하지 않았다. 서울에 거주할 때는 詩社를 결성하여 모임에 참여하기도 하였으나, 생애의 대부분을 외직을 떠돌며 유람과 詩文으로 보냈다. 耳溪 洪良浩(1724~1802)에 의하면 그는 經史에 밝고 詩賦에 뛰어났다. 그러나 세속에 얽매이지 않는 기질과 강직한 성품, 그리고 少論이라는 黨色으로 인해 크게 현달하지는 못했다. 조하망의 문학적 성취와 관련하여 가장 잘 알려진 것은 鏡浦臺와 관련된 작품이다. 1741년에 江陵府使로 부임하여 경포대를 중수하고 <鏡浦臺上樑文>을 지었는데, 이 작품은 당시에 膾炙되었다. 李裕元(1814~1888)은 林下筆記 에서 경포대와 관련한 역대 작가들의 뛰어난 詩를 소개하면서 조하망이 지은 <鏡浦臺>를 꼽았다. 그럼에도 불구하고 지금까지 조하망과 그의 詩文에 대한 관심은 적었으며, 본격적인 연구는 이루어지지 않았다. 이 논문에서는 이러한 사실에 주목하여 18세기 소론 文人인 조하망의 家系와 生涯 및 西州集 의 편찬과 詩篇의 구성에 대해 상세히 고찰하고, 특히 ｢模擬錄｣에 실린 擬作詩를 중심으로 작품의 성격과 특징을 살폈다. ｢모의록｣에 실린 시의 특징적인 면모는 車天輅의 樂府新聲 에 수록되어 있는 古樂府와 거의 일치하는 양상을 보인다. 첫째는 學唐風의 낭만성을 지향하는 작품이 주를 이루는 점, 둘째는 여성 정감이 돋보이는 艶情詩가 다수라는 점, 셋째는 7언 절구의 형식이 대부분이라는 점이다. 요약하자면, ｢모의록｣을 통해 살펴본 조하망은 前代 學唐風의 낭만성을 지향했던 시인들과 그들의 작품을 비판적 시각으로만 바라보지 않았다. 그는 비판적 시각을 견지하면서도 이전 시대의 문학적 전통을 적극적으로 수용하여 唐詩風의 선집류를 학습하고 여기에서 시의 재료를 취하여 唐詩의 시 취향과 특징을 습득하여 자기화의 과정으로 활용하였다. 이러한 詩認識과 學詩의 과정은 단순히 模擬에 그치지 않고, 그가 개성적이고 다양한 시 세계를 이루는 바탕이 되었다. 이 논문에서는 ｢모의록｣에 실린 의작시만을 대상으로 하였기 때문에 조하망이 지향했던 낭만적 당시풍이 악부시가 아닌 다른 형식의 시에서는 어떠한 양상으로 드러나는지에 대해서는 살피지 못했다. 이와 관련하여 추후 ｢모의록｣을 제외한 나머지 13편의 ｢詩錄｣과 그 안에 보이는 조하망의 작가의식 및 작품의 주제적 측면에 대한 다각적 고찰은 조하망 시세계의 전모를 논하기 위해서도 꼭 필요하다. Jo Ha-mang(曺夏望, 1682~1747) is a person belonging to Soron line in the late Joseon Dynasty, and his family clan is Chang-nyeong, his courtesy name is Ajung, and his pen name is Seo-ju. He advanced into official positions during the time of Gyeongjong and Yeongjo when the party strife between Noron line and soron line was most intense, but he was not greatly involved in the party strife. When residing in Seoul, he formed a poetry society and participated in the meetings, but he spent most of his life on the sightseengs and poetry and prose wandering in the outside positions. According to Lee-gye Hong Ryang-ho(洪良浩, 1724~1802), he was brilliant in classics and historic records and excellent in poetry and poetic writings. However, it was not able to achieve great eminence due to his temperament not fettered by the secular world and the upright character and the party color of Soron line. What is the most well known in connection with the literary achievements of Jo Ha-mang is a work related to Gyeongpodae. In 1741, he was appointed as Mayor of Gangneung and repaired Gyeongpodae and wrote “Commemoration on Framing Completion of Gyeongpodae”, and this work was widely known to everybody at the time. Lee Yu-won(李裕元, 1814~1888) introduced the excellent poems of writers of all the times related to Gyeongpodae in “Notes of Retired Life”, and he chose “Gyeongpodae” written by Jo Ha-mang. Nevertheless, there has been little interest in Jo Ha-mang and his poetry, and no full-fledged research has been done. In this paper, paying attention to such facts, I considered in detail the family line of Jo Ha-mang, the literary persom of Soron line in the 18th century and his life, the compilation of “Collection of Seo-ju” and the composition of the book of poems, and, especially, examined the features and characters of the works, focusing on the imitation poetry in “Imitation- Record”. The characteristic appearance of poems in “Imitation-Record” shows the aspect that almost corresponds with old folk songs included in “New Voices of Folk Songs” by Cha Cheon-ro. The first is that the works are mainly oriented towards the romantic nature of the scholarly Tang style, the second is that the majority are love poems that stand out women s feelings, the third is that the majority are the forms of 7 characters phrases. To sum up, Jo Ha-mang examined through “Imitation-Record” did not look at poets and their works, which aimed at the romanticism of the previous scholarly Tang style, only from a critical point of view. While adhering to a critical viewpoint, by actively accepting the literary tradition of the previous era, he learned the anthologies in Tang poetry style, and by taking materials of poetry here and learning the taste and characteristics of Tang poetry, he utilized it as a process of assimilation. The process of these poetry recognition and learning poetry were not just imitation, but became the basis for forming a unique and diverse poetic world. In this paper, I focused only on imitation poetry included in “Imitation- Record”, so I could not examine in what aspect the romantic Tang poetry style which Jo Ha-mang oriented, appeared in the poetry of other forms, not of folk songs. In relation to this, further diverse studies on remaining 13 “Poetry Records” excluding “Imitation-Record” and the writer consciousness of Jo Ha-mang and the thematic aspects in them are also necessary to discuss the whole picture of the poetic world of Jo Ha-mang.

Indium tin oxide (ITO) thin films show a low sheet resistance and high transmittance in the visible range of the spectrum. Therefore, they play an important role as transparent electrodes for flat panel displays. However, their resistivity is rather high for use as a transparent electrode in large displays. One way to improve electrical and optical properties in large displays is to use ITO/Ag/ITO multilayer films. ITO/Ag/ITO multilayer films have lower sheet resistance than single layer ITO films with the same thickness. Prior to the ITO/Ag/ITO multilayer experiments, optimal condition for thickness change are necessary. Their thicknesses were deposited differently in order to analyze electrical and optical properties. However, when optimal single film characteristics are applied to ITO/Ag/ITO multilayer films, other phenomena appeared. After analyzing the electrical and optical properties by changing ITO and Ag film thickness, ITO/Ag/ITO multilayer films were optimized. By combining ITO film at $586\;{\AA}$ and Ag film at 10 nm, the ITO/Ag/ITO multilayer films showed optimized high optical transmittance of 87.65%, and the low sheet resistance of $5.5{\Omega}/sq$.

$Y_2O_3:Eu^{3+}$ is an excellent red-emitting phosphor, which has been widely used for display devices due to highly luminescent property and chemical stability. In this study, $Y_2O_3:Eu^{3+}$ red phosphors were prepared using the solid state reaction and RF thermal plasma synthesis. The particle size of $Y_2O_3:Eu^{3+}$ phosphors obtained by the solid state reaction varied from 10 to $20{\mu}m$, and 30~100 nanometer sized $Y_2O_3:Eu^{3+}$ particles were obtained from a liquid form of raw material through RF thermal plasma synthesis without an additional heat treatment. Photoluminescence measurements of the obtained $Y_2O_3:Eu^{3+}$ particles showed a red emission peak at 611 nm ($^5D_0{\rightarrow}^7F_2$). PL intensity of red nano phosphors prepared by RF thermal plasma synthesis was comparable to that of red phosphors prepared by the solid state reaction, indicating that nano-sized $Y_2O_3:Eu^{3+}$ red phosphors could be successfully synthesized using one-step process of RF thermal plasma. $Y_2O_3:Eu^{3+}$는 우수한 적색 발광 특성을 가지고 있는 형광체로 최근 고화질 디스플레이에 대한 수요가 증가함에 따라 관련 연구가 활발히 진행되고 있다. 본 연구에서는 RF 열플라즈마 합성법과 고상법을 이용하여 $Y_2O_3:Eu^{3+}$ 적색 형광체를 합성하였으며, 합성 방법에 따른 $Y_2O_3:Eu^{3+}$ 적색 형광체의 결정 구조, 미세 구조, 발광 특성의 차이를 XRD, TEM, PL 분석을 통해 비교하였다. 고상법으로 합성된 $Y_2O_3:Eu^{3+}$ 적색 형광체의 입자는 약 $10{\sim}20{\mu}m$ 크기를 가지는 반면, RF 열플라즈마 합성법을 통해 합성된 적색 형광체는 반응부는 약 100 nm, 필터부는 약 30 nm의 크기를 갖는 나노 형광체로 확인되었다. 합성된 모든 분말들은 PL 측정결과 611 nm($^5D_0{\rightarrow}^7F_2$)에서 발광하는 것을 확인하였으며, 결정 크기와 입도가 증가할수록 PL intensity가 증가하였다. 또한, 추가 열처리 공정이 필요 없는 one-step 공정의 RF 열플라즈마 공정을 통해 합성된 $Y_2O_3:Eu^{3+}$ 적색 나노 형광체는 고상법으로 합성된 적색 형광체와 비슷한 발광 특성을 보이는 것을 확인할 수 있었다.

TMCP로 제조된 고강도 베이나이트강의 유효결정립도와 저온인성에 미치는 Cu와 B의 영향

이승용,황병철,Lee, Seung-Yong,Hwang, Byoungchul 한국재료학회 2014 한국재료학회지 Vol.24 No.10

Effects of Cu and B on effective grain size and low-temperature toughness of thermo-mechanically processed high-strength bainitic steels were investigated in this study. The microstructure of the steel specimens was analyzed using optical, scanning, and transmission electron microscopy; their effective grain size was also characterized by electron back-scattered diffraction. To evaluate the strength and low-temperature toughness, tensile and Charpy impact tests were carried out. The specimens were composed of various low-temperature transformation products such as granular bainite (GB), degenerated upper bainite (DUB), lower bainite (LB), and lath marteniste (LM), dependent on the addition of Cu and B. The addition of Cu slightly increased the yield and tensile strength, but substantially deteriorated the low-temperature toughness because of the higher volume fraction of DUB with a large effective grain size. The specimen containing both Cu and B had the highest strength, but showed worse low-temperature toughness of higher ductile-brittle transition temperature (DBTT) and lower absorbed energy because it mostly consisted of LB and LM. In the B-added specimen, on the other hand, it was possible to obtain the best combination of high strength and good low-temperature toughness by decreasing the overall effective grain size via the appropriate formation of different low-temperature transformation products containing GB, DUB, and LB/LM.

변형률 속도에 따른 Fe-24.5Mn-4Cr-0.45C 합금의 인장 특성과 동적 변형시효

이승용,황병철,Lee, Seung-Yong,Hwang, Byoungchul 한국재료학회 2016 한국재료학회지 Vol.26 No.5

In the present study, the tensile properties and dynamic strain aging of an Fe-24.5Mn-4Cr-0.45C alloy were investigated in terms of strain rate. During tensile testing at room temperature, all the stress-strain curves exhibited serrated plastic flows related to dynamic strain aging, regardless of the strain rate. Serration appeared right after yield stress at lower strain rates, while it was hardly observed at high strain rates. On the other hand, strain-rate sensitivity, indicating a general relationship between flow stress and strain rate at constant strain and temperature, changed from positive to negative as the strain increased. The negative strain-rate sensitivity can be explained by the Portevin Le Chatelier effect, which is associated with dynamic strain aging and is dependent on the strain rate because it is very likely that the dynamic strain aging phenomenon in high-manganese steels is involved in the interaction between moving dislocations and point-defect complexes.

In this study, in order to increase the span length, the temporary bridge which the center part of span is strengthened by small H-beam and the end part of span is strengthened by steel plate is designed and constructed. Real behavior of proposed temporary bridge is analyzed by field loading test. Analyzed shear buckling strengths and nonlinear behavior of suggested temporary bridge are compared with the those of general temporary bridge. From the field loading test results, it is analyzed that real static behavior of suggested temporary bridge is agree with the analyzed behavior which is considered in design process. Under the proposed design condition, it is investigated that the shear buckling strength of suggested temporary bridge is about 40% higher than that of general temporary bridge, and the ultimate strength of suggested temporary bridge is about higher than that of general temporary bridge. From the study results, it is concluded that the proposed temporary bridge can be applied by the needs of field condition.

Purpose: Orthognathic surgery is required in patients with severe skeletal disharmony and facial asymmetry, which results in functional and esthetic improvement. Recently, bimaxillary surgery has become generalized. Establishment of the occlusal plane among several other factors included in the surgery plan is a major consideration for the diagnosis and treatment plan and it is also an important factor for postoperative stability. Methods: In this study, we assessed postoperative stability of occlusal plane, B-point, and pogonion point on 20 patients who underwent two-jaw surgery in the Chosun Dental Hospital from 2000 to 2007. Preoperative and postoperative states and at least a one year postoperative follow-up were compared. Results: The postsurgical relapse volume of the occlusal plane to the SN plane and the FH plane was $-0.26{\pm}2.8^{\circ}$ and $-0.44{\pm}3.29^{\circ}$, respectively and after two-jaw surgery, the stability of occlusal plane was maintained. The horizontal relapse degree was $0.85{\pm}0.46$ mm and $0.76{\pm}0.48$ mm, respectively, and the vertical relapse degree was $1.16{\pm}0.36$ mm and $1.13{\pm}0.71$ mm of the B point and the Pogonion point at the time after minimal 1 year. Conclusion: The vertical relapse amount was shown to be slightly larger than the horizontal relapse amount.

Threshold limit value (TLV) test between expert and consumer panel was conducted about absolute, recognition and difference threshold respectively. And we tried to suggest appropriate and minimum acceptable menthol concentration level by consumer panel. Determination of threshold value was based on ASTM E 679-79 method by forced-choice ascending concentration series. In addition, a semi-ascending paired difference method was referred to conduct test. The group threshold value was determined as the value of geometric mean individual threshold. The smokers were dividend by two groups, trained and consumer panel. Trained panel was selected according to sensitivity to menthol discrimination. Consumer panel wasrecruited in proportion as population ratios including female smokers. They were all over twenty years old volunteers and summed up thirty four persons. In terms of sensor evaluation, overall difference test with seven-category scale by both trained and consumer panelists were done. On judging correct or incorrect answer, two by three cut-off levels applied to. Every test was conducted with two sessions, before smoking and during smoking period. And, only two samples served each paneI per test with regard to sensory fatigue and reliable results. All tests were replicated, and in total 32 times per panelist. In conclusion, the recognition threshold about consumer and expert panel was 358 ppm/cig. and 276 ppm/cig. in separately. Besides, absolute and difference thresholds were obtained also. And, we conduct difference threshold test with two different ways, upward and downward. And, The results of each method were 246, 195 ppm/cig., 1414, 1336 ppm/cig. and 1047, 972 ppm/cig.
