金鍾求 ( Kim Jong-gu ) 동방한문학회 2022 東方漢文學 Vol.- No.90

본 연구는 濯纓 金馹孫과 同人의 문화를 분석했다. 이를 위해 同人文化가 형성되어 작품으로 남겨진 모든 부분을 고찰했다. 그들의 同人文化는 다음과 같이 나타나고 있었다. 첫째, 김일손과 同人은 신분을 뛰어넘어 文으로써 交遊하는 문화가 드러나고 있었다. 김종직 학단과 그 문하·관료·친인척·생육신 등 다양한 신분과 자유롭게 문으로써 교유를 하고 있었다. 둘째, 김일손과 同人은 山水에 노니는 놀이문화가 나타나고 있었다. 특히 정여창, 김굉필과 함께한 산수유람은 의미가 있다. 그 외 누정과 강 등에서 뱃놀이를 하거나, 詩會를 열기도 했다. 셋째, 김일손과 同人은 지역 및 士林을 회합하는 문화를 형성하고 있었다. 이는 훗날 다른 학파에서 그 명맥이 이어지기도 했다. 김일손의 여러 기문과 서문에서 이러한 의식이 잘 나타나고 있었다. 김일손과 同人이 형성한 문화는 초기 사림파의 同人文化를 잘 확인할 수 있다. 이들은 文·山水·同人이 서로 결합해 그 즐거움을 만끽하며, 士林을 결집하는 역할을 하고, 지역사회에 그들의 이상을 실천하고자 했다. This study analyzed the culture of 金馹孫 and the same person. To this end, a sympathetic culture was formed and all the parts left as works were examined. Their cognate culture was manifested as follows. First, there was a culture in which Kim Il-son and the same person communicated with each other through writing, transcending their status. He was acquainted with the Kim Jong-jik Academy and his followers, bureaucrats, relatives, physical bodies, etc. and freely as a teacher. Second, a culture of play in which Kim Il-son and the same person played in the mountains and water was emerging. In particular, the landscape tour with Yeo-chang Jeong and Gong-pil Kim is meaningful. Other than that, they played boats in Nojeong and rivers, and held public demonstrations. Third, Kim Il-son and his contemporaries were forming a culture that brought together regions and communities. It was later carried on by other schools of thought. Kim Il-son's various keynotes and prefaces showed this consciousness well. The culture formed by Kim Il-son and the same person can clearly confirm the culture of the same person of the early Sarim school. They wanted to enjoy the joy of literacy, mountain water, and the same person united with each other, to play a role of uniting friendships, and to put their ideals into practice in the local community.

김종구,김동용,김현,한병동,조영래,Kim, Jong-Gu,Kim, Dong-Yong,Kim, Hyun,Hahn, Byung-Dong,Cho, Young-Rae 한국마이크로전자및패키징학회 2015 마이크로전자 및 패키징학회지 Vol.22 No.3

히트 싱크용 소재에 응용할 목적으로 단층금속과 2층금속 클래드메탈에 대해 열전도 특성에 대한 연구를 하였다. 단층시편으로는 스테인리스강과 알루미늄을 선택하였으며, 2층 금속으로는 스테인리스강과 알루미늄을 압연해서 제조한 클래드메탈을 사용하였다. 열전도도는 섬광법으로 측정한 열확산계수와 비열 및 밀도를 사용해 얻었다. 실험을 통해 얻은 측정값을 참고문헌에 보고된 자료를 사용해 얻은 계산값과 비교하였다. 단층시편의 경우, 실험을 통해 얻는 열확산계수와 열전도도는 계산값보다 작았다. 스테인리스강의 경우, 측정한 열전도도는 계산값에 비해 6% 정도 작았으며, 알루미늄의 경우 18% 정도 작았다. 반면, 2층 금속인 스테인리스강과 알루미늄의 클래드메탈은 측정한 열전도도가 계산값에 비해 55% 정도 낮게 나타났다. 섬광법으로 측정한 열전도도가 계산값보다 55% 정도 낮게 나타난 이유는 스테인리스강과 알루미늄의 사이에 존재하는 계면의 영향 때문이다. 스테인리스강과 알루미늄의 사이에 존재하는 계면은 열전도 특성을 지배하는 전자와 탄성파의 이동을 어렵게 하기 때문이다. 우수한 방열특성을 갖는 다층구조 방열모듈을 개발하기 위해서는 열전도 특성에 결정적으로 영향을 주는 계면 특성의 조절이 중요하다. A study on thermal properties for a single-layer metal and a 2-ply metal (clad metals) was investigated for the application of heat sink. For the single-layer metal, a stainless steel (STS) and an aluminum (Al) were selected. Also, a roll bonded clad metal with STS and Al was chosen for the 2-ply metal. The thermal conductivity of the sample was obtained from the thermal diffusivity measured by the light flash analysis (LFA), specific heat and density. Measured thermal property values were compared with the calculated values using the data from the references. For the single-layer metal, measured values for the thermal diffusivity and thermal conductivity were smaller than calculated values. Differences between measured and calculated values were about 6% and 18% for the STS and Al samples, respectively. For the clad metals, however, a large difference (55%) was observed. Here, a relatively small thermal conductivity measured by LFA was due to the existence of a interface between STS and Al in the clad metal. Such a interface reduces the moving velocity of free electrons and phonons in the clad metal. For the development of a high performance heat-issipation module with the multi-layer structure, the control of interface properties which determine thermal properties was confirmed to be important.

One of the most important factors that cause eutrophication is nutrient materials containing nitrogen and phosphorus which stem from excreation of terrestial sources and release from sediment. Therefore, to improve water quality, the reduction of these nutrients loads should be indispensible. At this study, the three-dimensional numerical hydrodynamic and ecosystem model, which was developed by Institute for Resources and Environment of Japan, were applied to analyze the processes affecting the eutrophication. The residual currents, which were obtained by integrating the simulated tidal currents over 1 tidal cycle, showed the presence of a typical counterclockwise eddies between Gyewha and Garyuk island. Density driven currents were generated westward at surface and eastward at the bottom in Saemankeum area where the fresh waters are flowing into, The ecosystem model was calibrated with the data surveyed in the field of the study area in annual average. The simulated results were fairly good coincided with the observed values within relative error of $30\%$. The simulations of DIN and DIP concentrations were performed using ecosystem model under the conditions of $40\~100\%$ pollution load reductions from pollution sources. In study area, concentration of DIN and DIP were reduced to $59\%$ and $28\%$ in case of the $80\%$ reduction of the input loads from fresh water respectively. But pollution loads from sediment had hardly affected DIN and DIP concentration, The $95\%$ input load abatement is necessary to meet the DIN and DIP concentration of second grade of ocean water quality criteria.

공동주택이 고층화됨에 따라, 고층 공동주택 거주자들은 이익을 누리는 반면에 건축물 배후를 이용하는 사람들은 주거 환경에서 많은 문제를 경험하게 되었다. 본 연구에서는 공동주택 중에서도 특히 공동주택의 높이가 도시경관에 미치는 영향에 대해 알아보기 위하여 사례 연구 및 비교 분석을 수행하였다. 그 결과, 해안지역의 공동주택 단지나 건축물들에 한해서는 그에 적합한 높이관리의 규제를 마련하여 여러 가지로 난립되어 있는 높이에 관한 제도들을 총괄적으로 관리 할 수 있는, 불안요소들을 모두 아우를 수 있는 방안이 모색되어야 할 것으로 판단된다. As apartments have been made into high-rise buildings, the residents in the buildings have become to enjoy the benefits. On the contrary, the users of buildings on the back have become to experience many problems in residential environments. This research studied on measures to improve height control systems focusing on the heights of apartments in order to figure out the impact of apartments on city scenery. This study concluded that, to solve these problems, a general system to control heights should be prepared to solve the problem of visual blocking and for apartment complexes or buildings in coastal areas, regulations for height controls suitable to them should be separately prepared thereby controlling systems related to height controls as a whole instead of those many different systems relating to heights.

To know characteristics of water quality in Saemankeum area, we were investigated the water quality of surface layer from July of 1999 to June of 2000. The concentrations of COD and chlorophyll a were in the range of $0.64\~6.40$ (mean 1.96)mg/L, $1.95\~51.55$ (mean 11,07)$mg/m^3$, respectively. The annual mean concentrations of DIN, DIP were found to be 21.182 $\mu$g-at/L and 0,655 $\mu$g-at/L respectively, which were exceeding second grade of seawater quality standard. The nitrogen ratio to the phosphorus was lower than 1. Therefore, nitrogen was playing an important role in phytoplankton growth as limiting factor in study area. Mean values of eutrophication index were exceeding 1, which was the eutrophication criteria. Especially Mankyung and Dongjin estuary were shown over 10 as eutrophication index. Therefore, Saemankeum area could be evaluated to possibility area for eutrophication. Released rate for ammonia nitrogen and phosphate phosphorus from sediments were 62.92 ${\mu}g-at/m^3/hr$ and 6.71 ${\mu}g-at/m^3/hr$, respectively.

Treatments of severely incurved toenails cause anatomical changes and cosmetic problems, even though they provide adequate symptom relief. Incurved toenail patients treated with a K-D$^{(R)}$ (S&C Biotech, Seoul, South Korea) the new device for correcting curved nail deformity were investigated retrospectively. This study surveyed 12 patients(18 cases) who had been treated for severe ingrown toenails using K-D$^{(R)}$ from May 2008 to March 2009, and examined their subjective satisfaction before and after the treatment. The average age of the participants was 39 (ranging from 27 to 52), and 8 of them were male and 4 female. The treatment was applied after the patients were given a thorough explanation about the tool and the treatment, and questionnaire surveys were conducted before the treatment and after 3 months on the average from the treatment. In the survey, the respondents were asked about pain, restriction on activities, and the selection of shoes. For each item, symptoms with a given point were presented, and the respondents' scores were compared between the surveys before and after the treatment. According to the results of the questionnaire survey, pain increased from 14 out of 40 before the treatment to 39 after, activity restriction increased from 11 to 30, and shoe selection increased from 20 to 30. The average total score increased from 45 to 98, and this suggests a considerable enhancement in the patients' subjective satisfaction. The average period of the application of K-D$^{(R)}$ was $20.3{\pm}9.4$ days, and in all the cases, ingrown toenails were corrected within three weeks.

줄포만 갯벌의 체계적이고 과학적인 관리를 위하여 갯벌 퇴적물을 대상으로 입도특성 및 유기물 그리고 중금속 조사를 실시하였고, 퇴적물중의 중금속 오염도를 평가하였다. 줄포만 전체 갯벌의 입도는 연안과 직각방향인 F라인에서 대부분 Clay질이 우세한 반면, 만의 연안측면에 위치한 R과 L라인에서 Silt질이 우세한 것으로 나타나서 Silt-Clay 또는 Clay-Silt가 대부분이었다. 평균입경은 3.7 ${\phi}{\sim}$ 10.4 ${\phi}$의 범위로 평균 7 ${\phi}$ 이상의 높은 평균입도를 나타내어 퇴적물 분류학상 세립질 퇴적물(4 ${\phi}$ 이상)에 해당되었다. 퇴적물의 유기물 농도는 연안에서 직각방향으로 뻗은 F라인에서 높게 나타난 반면, 연안 측면을 따라 조사된 L과 R라인에서 상대적으로 낮게 나타났다. 갯벌 퇴적물의 중금속 분포를 보면 연안의 직각방향인 F라인보다 연안측면의 R과 L라인에서 대체적으로 높은 중금속 농도를 나타내고 있었다. 유기물과 입도는 양호한 상관성을 보였고, 입도 평균치와 중금속의 일부 원소와 양호한 상관성을 나타내었지만, 중금속 원소간에는 약간의 상관성은 있었으나 대체적으로 낮은 상관계수를 보였다. 중금속 오염도 평가를 위하여 미국 EPA와 NOAA 그리고 한국 환경정책평가연구원에서 제시한 중금속 오염기준을 적용해 보았다. 줄포만 갯벌퇴적물의 중금속 오염도는 미국 EPA 기준에서 항목별 편차는 있었으나 대부분이 Nonpolluted와 Moderaterly polluted에 속하였고, NOAA의 기준에서는 대부분이 ERL 이하의 오염수준을 보였다. 한국 환경정책평가연구원에서 제시한 기준안에서는 대부분이 목표수준 이하의 값을 나타내었다. For the systematic scientific management of tidal flat sediment in Julpo bay of Korea, this study conducted a survey of particle composition, organic matter(l.L) and heavy metals for three lines ; including F, R and L lines in tidal flat sediment. Particle composition of tidal flat sediments consisted predominantly of clay at F line which was in right angle direction to the coast, whereas R and L lines were located horizontally along the coast and consisted predominantly of silt. Mean grain size values of tidal flat sediments were in the range of 3.7 ${\phi}{\sim}$10.4 ${\phi}$(average 7${\phi}$). The contents of heavy metals observed at R and L lines were lower than those at F line. The correlation analysis among heavy metals, organic matter and particle size was found to have a good interrelationship. For the evaluation of heavy metals pollution, two criteria of US NOAA and KEI(in Korea) were applied Heavy metals pollution level of tidal flat sediments belonged in Non polluted and Moderately polluted groups in US EPA criteria, and its pollution levels sat below ERL in NOAA criteria. The results of heavy metals pollution level obtained by KEI criteria were found to be less than the goal level.

김종구,박홍석,김현,한병동,조영래,Kim, Jong-Gu,Park, Hong-Seok,Kim, Hyun,Hahn, Byung-Dong,Cho, Young-Rae 한국마이크로전자및패키징학회 2015 마이크로전자 및 패키징학회지 Vol.22 No.4

히트 싱크용 소재에 응용할 목적으로 단층금속과 2층 단면구조 복합재료에 대해 열전도 특성을 연구하였다. 단층금속으로는 알루미늄합금(Al6061)을 사용했으며, 2층 단면구조 복합재료로는 Al6061기판에 질화알루미늄(AlN)을 스크린 인쇄한 층상구조 복합재료를 선택하였다. 섬광법으로 측정한 열확산계수와 비열 및 밀도를 사용해서 열전도도를 측정하였다. 실험을 통해 얻은 열전도 특성 값을 참고문헌에 보고된 자료를 사용해 계산한 값과 비교하였다. Al6061 기판에 스크린인쇄법으로 AlN 후막을 형성시킨 2층 단면구조 복합재료 시편의 열전도도는 AlN 후막의 두께가 증가할수록 선형적으로 감소하였다. 측정한 복합재료의 열전도도는 두께가 $53{\mu}m$과 $163{\mu}m$일 때, 각각 $114.1W/m{\cdot}K$와 $72.3W/m{\cdot}K$로 나타났다. 또한, 스크린 인쇄한 AlN 후막의 열전도도를 열전도비저항에 대한 혼합법칙을 적용해서 평가하였다. AlN 후막의 두께가 $53{\mu}m$와 $163{\mu}m$인 경우, 스크린 인쇄한 AlN 후막의 열전도도는 각각 $9.35W/m{\cdot}K$와 $12.40W/m{\cdot}K$로 나타났다. A study on thermal properties for a single-layer metal and two-layer composites was investigated for the heat-sink application. For the single-layer metal, an aluminum alloy (Al6061) was selected. A screen printed aluminum nitride (AlN) layer on the Al6061 substrate was chosen for the two-layer composites. The thermal conductivity of the sample was determined from the thermal diffusivity measured by the light flash analysis (LFA), specific heat and density. Measured thermal property values were compared to calculated values using the data from the references. The thermal conductivity of composites with screen printed AlN layer on the Al6061 substrate decreased linearly with increasing the thickness of AlN layer. Measured values of the thermal conductivity for composites with $53{\mu}m$ and $163{\mu}m$ thick AlN layers were $114.1W/m{\cdot}K$ and $72.3W/m{\cdot}K$, respectively. In particular, the thermal conductivity of the screen-printed AlN layer was demonstrated by appling the rule of mixture in view point of thermal resistivity. Measured values of the thermal conductivity for AlN layers with the thickness of $53{\mu}m$ and $163{\mu}m$ showed $9.35W/m{\cdot}K$ and $12.40W/m{\cdot}K$, respectively.

Objective: The objective of this study was to compare results of the macroscopic one-layer vasovasostomy with those of microscopic one-layer vasovasostomy and to analyze the change of semen parameters according to the interval of vasal obstruction. Method and Materials: Between March 1987 and December 1997, we performed 121 vasovasostomies using modified one-layer technique with loupe magnification (macroscopic vasovasostomy) or microscope. Among the 68 could be followed post-operatively, 37 patients were treated by macroscopic technique with loupe, and 31 patients by microscopic technique. We compared rates of anatomical patency (sperm count above than $10{\times}10^{6}$/ml) and pregnancy of macroscopic vasovasotomy with those of microscopic vasovasostomy. Patency and pregnancy rates according to vasal obstructive interval were also examined. Results: The patency rates of macroscopic and microscopic technique were 86.5% and 87.1%, and pregnancy rates of macroscopic and microscopic technique were 64.9% and 67.7%. There was no statistical significance between these two methods (p>0.05). The pregnancy rates and sperm motility were decreased if more than 10 years had elapsed following vasectomy (p<0.05). Conclusion: We found little difference in success rates resulting from macroscopic and microscopic vasovasostomy and the former had the advantage of reduced cost and a lower operator skill level. In post-operative semen analysis, the sperm motility was the most probable factor associated with vasal obstructive interval.
