This study aims at clarifying that Kim, So-Wol`s poetics is based on LiKi(理氣)philosophy. And this is to show the distinction between Western ideas like Romanticism which is accepted by Kim-uk and So-Wol`s traditional poetics. The results are as follows. First, So-Wol is realized paradoxical sense which can find out positive meaning from negative thing and overcome Western dichotomy by LiKijimyo(理氣之妙) principal means that Li(理) as Hyungisanja(形而上者: metaphysical thing) and Ki(氣) as Hyungihaja (形而下者: physical thing)are neither divided nor united. Second, So-Wol emphasizes that immutable character of Sihon(詩 魂) on his poetics because he wants to show Li`s character as inevitable cause and right. As he authorizes Sihon(詩魂) ontological and axiological character of Li, Sihon(詩魂) has Good truth and thereby has good effect for society. Unlike Kim-uk`s romanticism, to display subjectivity on So-Wol`s poetics is based on LiKi philosophy has a effect for society, because the subjectivity has a moral sensibility. Last, like Li and Ki, Sihon(詩魂) is manifested on poetry by Umyoung(陰影), so poetry is valuated by not Sihon but Umyoung. But So-Wol contradicted himself by asserting that Umyoung(陰影) isn`t discussed merits and demerits. This is explained by considering LiKijimyo(理氣之妙). Ki is a manifestation of Li, therefore when we see poetry as Ki with view is based on authenticity, Ki is not a thing of judgement. But when we poetry with view is based on substantiality, Ki is a thing of judgement. In conclusion, So-Wol intended to include not only eternal nature but also substantiality on modern poetry with LiKi(理氣) philosophy.

김지혜,김은영,김원백,김병수,이재천,신재수,Kim, Ji-Hye,Kim, Eun-Young,Kim, Won-Back,Kim, Byung-Su,Lee, Jae-Chun,Shin, Jae-Soo 한국자원리싸이클링학회 2010 資源 리싸이클링 Vol.19 No.4

A fundamental study was carried out to develop a process for recycling tungsten and cobalt from WC-Co hardmetal sludge generated in the manufacturing process of hardmetal tools. The complete extraction of cobalt and simultaneous formation of tungstic was achieved by treating the sludge using aqua regia. The effect of aqua regia concentration, reaction temperature and time, pulp density on cobalt leaching and tungstic acid formation was investigated. The complete leaching of cobalt was attained at the optimum conditions: 100 vol.% aqua regia concentration, $100^{\circ}C$ temperature, 60 min. reaction time and 400 g/L pulp density. A complete conversion of tungsten carbide of the sludge to tungstic acid was however, obtained at the pulp densities lower than 150 g/L under the above condition. The progress of reaction during the aqua regia treatment of the sludge was monitored through the XRD phase identification of the residue. The metallic impurities in the tungstic acid so produced could be further removed as insoluble residues by dissolving the tungsten values in ammonia solution. The ammonium paratungstate($(NH_4)_{10}{\cdot}H_2W_{12}O_{42}{\cdot}4H_2O$) of 99.85% purity was prepared from the ammonium polytungstate solution by the evaporation crystallization method. 초경공구의 제조공정에서 발생하는 WC-Co 초경합금 슬러지로부터 텅스텐의 순환활용을 위한 기초연구가 수행되었다. 왕수를 사용하여 슬러지로부터 코발트를 침출함과 동시에 탄화텅스텐을 텅스텐산으로 변환시켜 회수하였다. 왕수농도, 반응온도와 시간, 광액농도 등이 코발트의 침출과 텅스텐산의 생성에 미치는 영향을 조사하였으며 최적조건을 도출하였다. 왕수농도 100 vol.%, 반응온도 $100^{\circ}C$, 반응시간 60분에서슬러지의 광액농도가 400 g/L에 도달할 때 까지 슬러지로부터 코발트의 완전한 추출이 이루어졌으나, 슬러지에 존재하는 모든 탄화텅스텐이 텅스텐산으로 완전히 전환되는 것은 광액농도가 150 g/L 이하일 때 이었다. 생성된 텅스텐산을 암모니아 용액에 용해함으로서 금속 불순물들을 불용성 잔사로 제거하는 것이 가능하였다. 증발결정 공정을 통하여 정제된 암모늄 텅스테이트 용액으로부터 99.85%의 순도를 가지는 암모늄 파라텅스테이트($(NH_4)_{10}{\cdot}H_2W_{12}O_{42}{\cdot}4H_2O$)를 얻을 수 있었다.

풍력에너지는 낮에 비해 야간에 많은 잉여전력을 발생시키기 때문에 야간에 생산되는 전력은 버려지고 있는데, 이 문제를 해결하기 위해 풍력 등 재생에너지를 연계한 수전해 하이브리드 시스템 개발이 활발히 이루어지고 있다. 본 연구에서는 하이브리드 시스템 안전성 향상을 위해 국내 외 수전해 시스템 기준의 평가항목을 분석하였고, 평가 항목을 토대로 수전해 시스템의 안전성능 시험항목을 도출하였다. $5Nm^3/hr$급 수전해 시스템의 안전성능 평가를 위하여 시험항목 중 효율측정시험, 수소발생압력시험, 수소 순도시험을 평가하였다. 그 결과 수소발생량은 $5.10Nm^3/hr$, 스택효율은 $4.97kWh/Nm^3$로 산출되었고, 이때 발생한 수소의 순도는 99.993%로 국제기준 ISO 14687, SAE J2719에 명시된 순도보다 높은 순도의 수소를 생산하였음을 확인할 수 있었다. 본 연구 결과는 향후 수전해 시스템의 구축과 안전성능을 평가에 도움이 될 것이라고 기대한다. The wind energy produced at night is being discarded because of the excess power generated at night compared to daytime. To solve this problem, In this study, we analyzed the evaluation contents for evaluation of domestic and overseas water electrolysis systems and drew contents for safety performance contents test of the water electrolysis system based on the evaluation contents. The test contents produced the efficiency measurement test, the hydrogen generated pressure test, and the hydrogen purity test. And the safety performance evaluation of the alkaline water electrolysis system of $5Nm^3/hr$ was performed based on the results. As a result, the hydrogen generation was calculated as $5.10Nm^3/hr$ and the stack efficiency was $4.97kWh/Nm^3$. The purity of the hydrogen generated was 99.993% and it was confirmed that it produced high purity hydrogen. I think will help us assess and build safety performance of water electrolysis systems in the future.

This study is to analyze representation of the youth shown in Son, Chang-seob’s serial novels in newspapers. His serial novels in newspapers are closely connected to the situation of politics and society of 1960s and it reflects identity of a social class as well as awareness of society issues among the public. Also, it shows rapidly changing generation of Korean society and moral regulations through love affairs happening between male and female characters who just had become old generation. Those characters who are playing unique roles in his novel are in their 20s either university students or people who are starting out a career. They confront with old generation due to difference in moral regulation or they reveal irrationality by showing resistance against society. This study particularly analyzed representation of the youth shown in his novels titled 『husband and wife』, 『A classroom of human beings』, 『Father and Two Daughters』 and 『Sons』 that show confrontation between old generation and young generation. Son, Chang-seob criticizes hypocrisy and corruption among materialized old generation through young characters. First type of young people is stuck in the self-contradiction or copies old generation during the process of fighting against old generation. Second type of young people reflects on corruption of Korean society and dreams of becoming a new father. Son, Chang-seob diagnoses corruption of Korean society while showing hopes for future through representation of the youth. Representation of the youth is meaningful as it criticizes corruption of Korean society but it also has limitations since it accepts the national ideology of the time.

저소음 프로펠러 설계를 위한 부분공동 유동의 점성 및 비점성 수치해석 비교 연구

김지혜,안병권,박철수,김건도,Kim, Ji-Hye,Ahn, Byoung-Kwon,Park, Cheol-Soo,Kim, Gun-Do 한국음향학회 2014 韓國音響學會誌 Vol.33 No.6

선박용 프로펠러가 수중에서 빠른 속도로 회전할 때, 날개 표면의 국부적인 압력이 낮아짐에 따라 불가피하게 여러 형태의 공동이 발생한다. 이러한 공동현상은 근본적으로 날개 단면의 기하학적 형상 특성과 수동력학적 운용조건에 의해 결정되며, 결과적으로 선박 프로펠러에서 유기되는 수중방사소음은 공동의 발생특성과 직결된다고 할 수 있다. 따라서 저소음 프로펠러 설계를 위해서는 날개 단면의 형상에 따라 발생하는 공동과 그에 따른 소음특성을 이론 및 실험을 통해 정량적으로 평가할 수 있어야 한다. 본 연구에서는 저소음 프로펠러의 설계단계에서부터 적용이 가능한 부분공동성능 해석법 개발 및 날개단면 형상정보 도출을 목표로 선박용 프로펠러 날개 단면에서 발생하는 부분공동 다상 유동의 비점성 수치해석을 수행하였다. 또한 점성해석 상용프로그램인 FLUENT에서 제공하는 난류 및 공동 모델 조합에 따른 결과를 살펴보았으며, 점성 및 비점성 해석 결과를 비교, 평가 하였다. When a ship propeller having wing type sections rotates at high speed underwater, local pressure on the blade decreases and various types of the cavitation inevitably occur where the local pressure falls below the vapor pressure. Fundamentally characteristics of the cavitation are determined by the shapes of the blade section and their operating conditions. Underwater noise radiated from a ship propeller is directly connected to the occurrence of the cavitation. In order to design low noise propeller, it is preferentially demanded to figure out key features: how the cavity is generated, developed and collapsed and how the effect of viscosity works in the process. In this study, we first perform inviscid analysis of the partial cavity generated on two dimensional hydrofoil. Secondly, viscous analysis using FLUENT with different turbulence and cavitation models are presented. Results from both approaches are also compared and estimated.

김지혜,박상원,방몽숙,양홍서,박하옥,임현필,오계정,김현승,이광민,이경구,Kim, Ji-Hye,Park, Sang-Won,Vang, Mong-Sook,Yang, Hong-So,Park, Ha-Ok,Lim, Hyun-Pil,Oh, Gye-Jeong,Kim, Hyun-Seung,Lee, Kwang-Min,Lee, Kyung-Ku 대한치과보철학회 2007 대한치과보철학회지 Vol.45 No.2

Statement of problem: Titanium and its alloy, with their excellent bio-compatibility and above average resistance to corrosion, have been widely used in the field of dentistry. However, the excessive oxidization of titanium which occurs during the process of firing on porcelain makes the bonding of titanium and porcelain more difficult than that of the conventional metal-porcelain bonding. To solve this problem related to titanium-porcelain bonding, several methods which modify the surfaces, coat the surfaces of titanium with various pure metals and ceramics, to enable the porcelain adhesive by limiting the diffusion of oxygen and forming the adhesive oxides surfaces, have been investigated. Purpose: The purpose of this study was to know whether the titanium-porcelain bonding strength could be enhanced by treating the titanium surface with gold and TiN followed by fabrication of clinically applicable porcelain-fused-to-titanium crown Material and method: The porcelain-fused-to-titanium crown was fabricated after sandblasting the surface of the casting titanium coping with $Al_2O_3$ and treating the surface with gold and TiN coating followed by condensation and firing of ultra-low fusing porcelain. To compare with porcelain-fused-to-titanium crowns, porcelain-fused-to-gold crowns were fabricated and used as control groups. The bonding strengths of porcelain-fused-to-gold crowns and porcelain-fused-totitanium crowns were set for comparison when the porcelain was fractured on purpose to get the experimental value of fracture strength. Then, the surface were examined by SEM and each fracturing pattern were compared with each other Result:Those results are as follows. 1. The highest value of fracture strength of porcelain-fused-to-titanium crowns was in the order of group with gold coating, group with TiN coating, group with $Al_2O_3$ sandblasting. No statistically significant difference was found among the three (P>.05). 2. The porcelain-fused-to-gold crowns showed the highest value in bonding strength. The bonding strength of crowns porcelain-fused-to-titanium crowns of rest groups showed bonding strength reaching only 85%-94% of that of PFG, though simple comparision seemed unacceptable due to the difference in materials used. 3. The fracturing patterns between metal and porcelain showed mixed type of failure behavior including cohesive failure and adhesive failure as a similar patterns by examination with the naked eye and SEM. But porcelain-fused-to-gold crowns showed high incidence of adhesive failure and porcelain-fused-to-titanium crowns showed high incidence of cohesive failure. Conclusion: Above results proved that when fabricating porcelain-fused-to-titanium crowns, treating casting titanium surface with gold or TiN was able to enhance the bonding strength between titanium and porcelain. Mean value of masticatory force was found to showed clinically acceptable values in porcelain bonding strength in all three groups. However, more experimental studies and evaluations should be done in order to get better porcelain bonding strength and various surface coating methods that can be applied on titanium surface with ease.

김지혜,정한석,강문성,송인홍,박승우,Kim, Ji Hye,Jeong, Han Seok,Kang, Moon Seong,Song, In Hong,Park, Seung Woo 한국농공학회 2012 한국농공학회논문집 Vol.54 No.6

The objectives of this study were to develop a linked watershed-waterbody modeling system and to assess the impacts of indirect wastewater reuse on irrigation water quality. The Osan stream watershed within Gyeonggi-do of South Korea was selected for this study. The linked modeling system was composed of the SWAT (Soil and water assessment tool) and QUALKO2 models. The SWAT model was calibrated and validated using the stream discharge and water quality data from 2010 to 2011. Runoff and non-point source pollutants from each subbasin and stream discharge from 1980 to 2009 were simulated by the SWAT model and applied to the QUALKO2 model. The QUALKO2 model was calibrated and validated under the conditions of low water and normal discharges, respectively. Finally, The 10-day irrigation water quality from April to September was simulated. The statistical measures of coefficient of determination ($R^2$), reliability index (RI), and efficiency index (EI) were used to evaluate the system performance. The $R^2$, RI and EI values ranged from 0.5 to 1.0, 1.03 to 1.92, and -35.03 to 0.95, respectively. The 10-day irrigation water quality showed the concentrations of BOD and coliform exceeded the water quality guidelines for wastewater reuse. The linked modeling system can be a useful tool to estimate non-point source pollutant loads in watershed and to control the water quality of effluent from a wastewater treatment plant and irrigation water in the downstream waterbody.

This study was carried on comparison of forage yields and growth of cropping system as forage (winter & summer) in Cheonan 2015~2016. The species of forage crop used were Barley (cv. Youngyang), Sorghum (cv. SX17), Proso millet (domestic) and Japanese millet (cv. Jeju). Plant height is the lowest when harvested in lough stage than in the harvests of all summer crops. The dry matter yield of lough stage was 1,343 kg/10a in barley. Looking at the dry matter according to cropping systems, the sorghum was higher at 10,018 kg when harvested at the lough stage than at the harvest. Dry matter of Proso millet and Japanese millet also had higher at the lough stage than at other harvest times. ADF content of sorghum was lower than that of harvesting, but Proso millet and Japanese millet showed higher ADF content in lough stage. The NDF content of the three crops was higher than that of the harvests, and crude protein content was higher in harvest than that of at lough stage. Total production of crude protein against dry matter yield was about 761 kg when sorghum was harvested at lough stage. There was no difference in the content of TDN among three crops according to harvesting time.
