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.

The hydrogen embrittlement of two austenitic high-manganese steels was investigated using tensile testing under high-pressure gaseous hydrogen. The test results were compared with those of different kinds of austenitic alloys containing Ni, Mn, and N in terms of stress and ductility. It was found that the ultimate tensile stress and ductility were more remarkably decreased under high-pressure gaseous hydrogen than under high-pressure gaseous argon, unlike the yield stress. In the specimens tested under high-pressure gaseous hydrogen, transgranular fractures were usually observed together with intergranular cracking near the fracture surface, whereas in those samples tested under high-pressure gaseous argon, ductile fractures mostly occurred. The austenitic high-manganese steels showed a relatively lower resistance to hydrogen embrittlement than did those with larger amounts of Ni because the formation of deformation twins or microbands in austenitic high-manganese steels probably promoted planar slip, which is associated with localized deformation due to gaseous hydrogen.

본 논문에서는 on-chip oscilloscope의 sub-sampler를 위한 클록을 생성하기 위한 두 가지 방식의 주파수 합성기를 제안한다. 제안하는 두 가지의 주파수 합성기는 지연고정루프 기반의 위상 선택기를 이용한 구조와 분수 분주형 위상고정루프를 이용하는 구조를 가지며 시뮬레이션 결과를 비교함으로써 각 구조의 특성이 분석된다. 제안된 두 회로 모두 1V 공급전압을 이용하는 65-nm CMOS 공정에서 설계되었으며, 125 MHz의 주파수를 가지는 입력 클록에 대해 121.15 MHz의 주파수를 가지는 출력 클록을 생성한다. 지연고정루프 기반의 위상 선택기를 이용한 주파수 합성기는 0.167 $mm^2$의 면적을 가지며 출력 클록은 2.88 ps의 지터 특성을 나타나며, 4.75 mW의 전력을 소모한다. 분수 분주형 위상고정루프를 이용한 주파수 합성기는 0.662 $mm^2$의 면적을 가지며 7.2 ps의 지터 특성을 나타내며, 1.16 mW의 전력을 소모한다. Two frequency synthesizers are proposed to generate a clock for a sub-sampler of an on-chip oscilloscope in this paper. These proposed frequency synthesizers are designed by using a multi-phase delayed-locked loop (DLL)-based phase selector and a fractional-N phase-locked loop (PLL), and they are analyzed by comparing simulation results of each frequency synthesizer. Two proposed frequency synthesizers are designed using a 65-nm CMOS process with a 1V supply and output the clock with the frequency of 121.15 MHz when the frequency of an input clock is 125 MHz. The designed frequency synthesizer using a multi-phase DLL-based phase selector has the area of 0.167 $mm^2$ and the peak-to-peak jitter performance of 2.88 ps when it consumes the power of 4.75 mW. The designed frequency synthesizer using a fractional-N PLL has the area of 0.662 $mm^2$ and the peak-to-peak jitter performance of 7.2 ps when it consumes the power of 1.16 mW.

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 $5.5{\Omega}/sq$.

이승용,김명희,주수종,Lee, Seung-Yong,Kim, Myung-Hee,Joo, Su-Chong 한국정보처리학회 2004 정보처리학회논문지D Vol.11 No.1

현재 멀티 데이터베이스 시스템에서 실의 처리의 향상을 위해 응용되고 있는 뷰 관리에 대한 대표적인 연구 경향은 실체 뷰 기법과 시그니쳐 뷰인덱스 기법에 관심이 집중되고 있다. 그러나 이들 두 기법의 비교에서 보면, 실체 뷰 기법은 빠른 액세스 시간을 가지지만 많은 저장 공간이 필요하고, 뷰 인덱스 기법은 적은 저장공간을 사용하지만 액세스 시간이 느리다는 상반된 특성을 가지고 있다. 따라서, 본 논문에서는 신체 뷰와 시그니쳐 뷰인덱스 혼용 기법을 제안하여 질의 처리시에 뷰 관리를 사용함으로써 시스템 성능을 향상시키고, 디스크 입/출력에 대한 액세스 비용을 줄이고자 한다. 본 논문에서는 이 기법에 대한 메타데이타 구조와 알고리즘들에 대해 제안하고 있다. Now, the representative researching trends of view managements for improving the query processing in multi-database system are focused on the materialized view mechanism and the signature view index mechanism. But when we compare with both mechanisms, the former mechanism's access time is faster than one of the latter's, and needs large space. The latter mechanism needs small space and the access time is slower than one of the former. These mechanisms are trade-off each other. Therefore, in case of query process using the view management, we are to improve the system performance and to reduce the access cost of disk input and output by suggesting a new mechanism mixing both the materialized view mechanism and the signature view index mechanism. We suggested that the structure of metadata and the algorithm about the new mired mechanism.

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.

In this study, recrystallization behaviors in the two-phase (${\alpha}+{\gamma}$) region of micro-alloyed steels such as Base, Nb, TiNbV and CAlN were investigated in terms of flow stress, microstructure and associated grain boundary characteristics. The flow stress of all specimens reached peak stress and gradually decreased, which means that recrystallization or recovery of proeutectoid deformed ferrite and recovery or transformation to ferrite of deformed austenite occurred by thermal activation. The precipitation of carbide or nitride via the addition of micro-alloying elements, because it reduced prior austenite grain size upon austenitization, promoted transformation of austenite to ferrite and increased flow stress. The strain-induced precipitation under deformation in the two-phase region, on the other hand, increased the flow stress when the micro-alloying elements were dissolved during austenitization. The recrystallization of the Nb specimen was more effectively retarded than that of the TiNbV specimen during deformation in the two-phase region.

2차원 흑연구조를 갖는 카본나노시트는 큰 비표면적과 우수한 전기적, 화학적 및 기계적 물성으로 인하여 미래소재로 각광받고 있다. 경제적이고 쉬운 카본나노시트의 양산공정개발을 위해 본 연구에서는 메테인($CH_4$)과 프로페인($C_3H_8$) 가스를 이용한 유도 열플라즈마 공정을 통해 기상 합성하여 카본나노시트 분말을 합성하였다. 유도 열플라즈마를 이용한 카본나노시트 합성은 촉매나 증착공정 없이 진행되었으며, 합성된 카본나노시트의 물성을 TEM, Raman, XRD, BET로 분석하였다. 메테인과 프로페인으로부터 합성된 카본 나노시트는 각각 5~6개의 그래핀 층과 15~16개의 그래핀 층으로 이루어진 분말로 합성되었으며 분말의 크기는 약 100 nm임을 확인할 수 있었다. An ultrathin sheet-like carbon nanostructure provides an important model of a two-dimensional graphite structure with strong anisotropy in physical properties. As an easy and cheap route for mass production, RF thermal plasma synthesis of freestanding carbon nanosheet from $CH_4$ (Methane) and $C_3H_8$ (Propane) is presented. Using vapor synthesis process with RF inductively thermal plasma, carbon nanosheets were obtained without catalysts and substrates. The synthesized carbon nanosheets were characterized using transmission electron microscopy (TEM), Raman spectroscopy, X-ray diffraction (XRD) and Brunauer-Emmett-Teller (BET) analysis. The carbon nanosheets synthesized using methane and propane generally showed 5~6 and 15~16 layers with a wrinkled morphology and size of approximately 100 nm.

과대공을 갖는 고장력 볼트 이음부의 역학적 거동에 관한 실험 및 해석적 연구

이승용,박영훈,조선규,장동일,Lee, Seung Yong,Park, Young Hoon,Cho, Sun Kyu,Chang, Dong Il 한국강구조학회 1998 韓國鋼構造學會 論文集 Vol.10 No.3

To evaluate the mechanical behavior and the compressive stress distribution in high tension bolted joints according to the size of bolt hole, the experimental and analytical studies are performed with enlarging bolt hole size. In experimental study, the static test is performed to measure the slip coefficient, and the fatigue test is also performed to evaluate the fatigue strength and failure pattern of fatigue crack. In analytical study, the compressive stress distribution is investigated by using the finite element analysis. From the result of experimental study, the slip coefficient and fatigue strength of the high tension bolted joints with oversize hole are not much different but somewhat it has decreased. These are because the size of bolt hole is larger than the holes of nominal size, therefore the width of clamping force is decreased and the compressive stress distribution area is smaller, this is certificated in the finite element analysis. In addition, the origin of fatigue crack in the oversize holes is closer to the hole than in the holes of nominal size, consequently it is investigated that the origin of fatigue crack is intimately associated with the compressive stress distribution which is formulated by the clamping force in both base metal and splice plate. 볼트 구멍의 크기가 고장력 볼트 이음부의 역학적 거동 및 내부 압축응력 분포에 미치는 영향을 살펴보기 위하여 과대공 및 표준공을 갖는 고장력 볼트 이음부에 대한 실험 및 해석적 연구를 실시하였다. 실험적 연구에서는 정적 인장시험과 피로시험을 실시하여 미끄러짐 특성, 피로강도 및 피로파단 양상을 평가하였으며, 해석적 연구에서는 유한요소해석을 통하여 내부 압축응력의 분포영역을 밝히고, 내부 압축응력의 분포가 역학적 거동에 미치는 영향을 평가하였다. 실험결과, 과대공을 갖는 고장력 볼트 이음부의 미끄러짐 계수와 피로강도는 표준공을 갖는 이음부와 비교하여 큰 차이는 없으나 다소 감소하는 경향이 나타났다. 이러한 원인은 과대공 시험편의 경우 볼트 구멍의 크기가 표준공 시험편과 비교하여 상대적으로 크기 때문에 축력의 작용폭이 좁아져 마찰영역으로 작용하는 내부 압축응력의 분포영역이 작아지기 때문으로 판단되며, 이는 유한요소해석 결과로도 확인할 수 있었다. 또한, 피로시험 결과 과대공 시험편의 피로균열의 발생점이 표준공 시험편 보다 볼트 구멍 내벽에 가까운 것을 알 수 있어, 피로균열의 발생위치는 고장력 볼트의 도입축력에 의해 모재와 이음판에 형성되는 내부 압축응력의 분포영역과 밀접한 관계가 있음을 알 수 있었다.
