珠潭 金聖運을 통해 본 18세기 초 경상우도 유림 동향

구진성(Gu, Jin-seong) 대동한문학회 2020 大東漢文學 Vol.63 No.-

이 글은 주담 김성운의 가계와 생애를 통해, 그의 학문적･당파적 정체성과 아울러 18세기 초 경상우도 유림의 동향을 살펴보기 위해 작성되었다. 김성운은 ‘남명학파 남인’으로 부를 수 있을 정도로 남명학파적인 성향을 진하게 지니고 있었던 동시에, 숙종조 집권 서인에 대응하여 뚜렷한 남인의 특징을 지니고 있었다. 그는 고조부 김대명으로부터 이어진 학파의 전통을 계승하여 당대 덕천서원을 이끄는 인물 중 하나였는데, 이는 정인홍 계열의 남명학파가 배제된 학파 내 지형 속에서 이루어진 것이었다. 그는 침체된 남명학파를 부흥시키기 위해 이만부와 같이 저명한 외부 인사를 초빙하는 등 지역 내외의 인물들과 적극적으로 교유하였다. 남인으로서 그의 뚜렷한 행적은 『주담집』 속 그의 여행 기록에서 드러나는데, 이를 통해 당시 경상우도 유림의 동향도 살펴 볼 수 있다. 특히 과거시험장에서 벌어진 사건 기록이나 관련한 자신의 논평을 통해, 숙종 조에 발생한 첨예한 사안을 받아들이는 유림의 태도와 김성운의 인물 성격을 엿볼 수 있다. 또한 경종 즉위 이후의 정국 동향도 여정 중에 관심을 기울여 기록하였다. This article was written to examine the trends of Confucian scholars in Gyeongsangwu-do in the early 18th century as well as his academic and partisan identity through the family and life of Judam[珠潭] Kim, Seong- woon[金聖運]. He had a strong tendency to Nammyeong School[南冥學派] and he had a strong characteristic of Namin[南人] in response to King Sukjong era s ruling party. Therefore he could define as “Nammyeong School Namin”. He was one of the leaders of the DeokcheonSeowon[德川書院] Confucian Academy, succeeding the tradition of the school from the great-great-grandfather Kim, Dae-myeong[金大鳴]. This was done within the internal dynamics relation of the Nammyeong School in which a group of Jeong, In-hong[鄭仁弘] s disciples was excluded. In order to revive the depressed Nammyeong School, he actively interacted with local and outer region figures by inviting prominent external figures like Lee, Man-bu. His distinct track record as Namin is revealed in his travel records. Through this, we can also see the trends of the Confucian scholars in Gyeongsangwu- do at that time. Especially through the record of the incident in place of state examination and his own comments, we can see the attitude of Gyeongsang-do Confucians accepting partisan events and the character of Kim, Sung-woon. In addition, the political situation after the enthronement of King Gyeongjong was recorded with interest during the journey.

A 48-year-old male visited the emergency room of the authors’ hospital due to nausea, vomiting, and myalgia for four days. Acute hepatitis A was identified from the serologic marker of the hepatitis A virus. Mild elevation of the serum creatinine and creatinine phosphokinase(CPK) suggested rhabomyolysis, which was confirmed with the serum aldolase, myoglobin, and urine myoglobin. With supportive care, both the liver and renal func- tions were recovered gradually and fully. This case shows that rhabdomyolysis can be one of the mechanisms of renal complication in cases of acute symptomatic hepatitis A.

Tensile and low-cycle fatigue (LCF) tests were carried out in a wide temperature range from 20℃ to 750℃ at strain rates of 1×10^(-4)~1×10^(-2)/s for 17% cold worked 316L stainless steel to investigate the conditions for the occurrence of dynamic strain aging (DSA) and its effects on material properties during tensile and LCF deformations. DSA introduced anomalous changes of tensile and LCF properties, and the DSA regimes under tensile and LCF loading conditions coincided with each other. During tensile deformation, DSA can be manifested in the forms of the plateau in the variation of strength with temperature, the minima in the variation of ductility with temperature, serrated yielding in the stress-strain curves, and the negative strain rate sensitivity (SRS). In case of LCF deformation, it can be manifested in the forms of the occurrence of the plateau or the peak in the variation of cyclic peak stress with temperature, the negative temperature dependence of plastic strain amplitude or softening ratio, the negative SRS, and the negative strain rate dependence of plastic strain amplitude or softening ratio.

레이저 가공시 조사되는 레이저 빔의 특성을 나타내는 변수 - 예를 들면, 빔의 형상, 초점면과 소재사이의 거리, 빔 강도 분포, 빔의 발산각, 실제 빔이 퍼져가는 양상이 이상적인 Gaussian 빔에 비해 얼마나 큰지를 나타내는 beam quality factor 등 - 이 가공결과에 큰 영향을 미치는 것은 경험적으로 잘 알려져 있다. 특히 원적외선 레이저로 천공, 에칭 또는 엑사이머 레이저로 ablation 가공을 수행할 때는 이러한 빔특성 변수의 영향이 극대화된다. 본 연구에서는 중요한 빔특성 변수의 영향을 가능한 독립시켜 정성적 및 정량적으로 파악하기 위해 연속발진 모드의 레이저빔 사용시 열전도에 의한 손실을 고려하였으며, 문제를 단순화해 빔 또는 가공소재의 상대적인 움직임이 없는 천공 (또는 에칭제거)의 경우에 대하여, 수치모사를 통해 여러 가지 빔 변수의 변화가 가공결과에 미치는 영향을 살펴보았다. 레이저 빔의 초점의 위치를 표면에서 멀리하면 가공깊이는 감소하게 되며, 같은 간격일 때는 소재의 내부에 위치시키는 것이 다소 유리하다. 또한 빔의 발산각이 작고, beam quality factor 값이 1에 가까울수록 깊은 가공을 얻을 수 있음을 파악하였다. In laser machining such as drilling with CO_2 or Nd:YAG laser, and etching or ablation with Excimer laser, one of the most important parameters affecting the machining results is known to be beam characteristics. In this paper a study is performed through a numerical simulation with the appropriate model to investigate the effects of beam parameters qualitatively and quantitatively, especially in the process of laser drilling of ceramics and ceramic composites. Results of different beam conditions reveal that the machined hole becomes deeper as (ⅰ) the beam divergence gets smaller,(ⅱ) beam quality factor approaches unity, and (ⅲ) beam focus lies nearer to the surface of the workpiece.

Objectives: We surveyed the prevalence of smoking among the adolescent population and analysed the correlation of the two exposure biomarkers-concentration of blood cadmium and urinary cotinine-to the smoking status. Methods: Subjects were 193 middle and high school students in Chungnam province. Blood cadmium and urinary cotinine were compared by sex and smoking status. Smoking status were classified by either the concentration of urinary cotinine or subjective answering as a smoker in the questionnaire. Results: Smoking prevalence was 24.6%, 36.2% and 6.7% among all subjects, male and female subjects, respectively. Average smoking amount was 17.5 and 1.5 cigarettes per month among the male subjects and female subjects, respectively Mean concentration of urinary cotinine among the male subjects was 135.57 ㎍/ℓ, and that of female subjects was 116.59 ㎍/. Direct smokers showed higher concentration of urinary cotinine than those of indirect smokers, and subjects with higher urinary concentration showed higher prevalence of smoking, too. Mean concentration of blood cadmium was 0.0572 ㎍/㎗ among the male subjects, and 0.0693 ㎍/㎗ among the female subjects. Among the male subjects, both exposure biumarkers showed significant correlation to the smoking status, but among the female subjects urinary cotinine did not show significant correlation to the smoking status. Conclusion: Concentrations of these two biomarkers suggested that this population had significantly high evironmental tobacco smoking(ETS) and efficient stop-smoking programs to reduce ETS should be directed to this population. Key words : environmental tobacco smoking, urinary cotinine, blood cadmium

저주기 피로변형시 316L 스테인리스강의 비안정화 거동에 미치는 온도의 영향 : 반복응력거동 및 적정 피로수명인자 Cyclic Stress Response and a Suitable Fatigue Parameter

홍성구,이순복 대한금속재료학회 2005 대한금속·재료학회지 Vol.43 No.1

In this study, cold worked (CW) 316L austenitic stainless steel was investigated by performing low-cycle fatigue test with varying temperature, strain amplitude, and strain rate. CW 316L stainless steel underwent additional hardening at room temperature and in the temperature range of 250-600℃: The hardening at room temperature came from plasticity-induced martensite transformation, and the hardening over 250-600℃ was attributed to dynamic strain aging. These hardening mechanisms competed with the softening mechanism which was induced by dynamic recovery, generally observed in cold worked materials, resulting in the cyclical non-stabilization of the material. Three fatigue parameters, such as stress amplitude, plastic strain amplitude, and plastic strain energy density, were evaluated. The results revealed that plastic strain energy density was nearly invariant through a whole life and, thus, recommended as a suitable fatigue parameter. (Received September 3, 2004)

This paper describes an approach for estimating the unsteady flowrate through a hydraulic pipe lines and a components in real time. Concerning the dynamic characteristics of a hydraulic pipe lines, experimental research from the view point of focusing on the unsteady flowrate through a pipe is insufficient because of the lack of adequate flowmeters. In this experiment, a new instantaneous flowrate measurement system making use of a sharp-edged cylindrical choke and LDV has been proposed and developed by the authors. The unsteady flowrate is obtained from the measurements center-line velocity of a circular pipe using LDV and the pressure difference using a sharp-edged cylindrical choke, and experiments on the frequency characteristics are carried out. The results show a good agreement between the estimated and directly measured flowrate waveforms illustrates the validity of the method proposed here.

Sampling frequency is important in stream water quality monitoring and assessment, especially in small agricultural watersheds. Flow rates and water quality could change dramatically in the watersheds. In this study, two different sampling schemes were compared to evaluate the effects of the sampling frequency on stream water quality assessment. A year water quality data was used for this purpose that was a part of results obtained from a water quality monitoring project performed to evaluate the impact of best management practices on stream water quality for 10 years, in Nomini Creek watershed in the United States. The data was separated into two groups, a continuous sampling and a scheduled sampling. The continous sampling data was based on the samples taken by an automatic water sampler and the scheduled sampling was by visiting the watershed on every one or two-week intervals. The results showed that both flow-based average concentrations and loading of total suspended solids (TSS) and total Kjeldahl nitrogen (TKN) were significantly different between the two sampling schemes while those of nitrate nitrogen, ammonium nitrogen, and total phosphorus were not. These differences were apparently resulted from the fact that some water quality items such as TSS and TKN were sensitive to the rainfall events and the continuous sampling could catch the fluctuation of the changes in the concentrations during those events.
