이상호(Lee Sang-ho) 한국동양철학회 2009 동양철학 Vol.0 No.32

이 논문은 19세기 초 호파계열에서 병호시비를 주도했던 류건휴의 『계호학적』과 『이학집변』을 중심으로, 후기 영남학인들의 도통과 이단에 대한 인식을 살펴보고 있다. 특히 이 두 책은 이황의 적통이 누구에게 이어졌는지를 중심으로 진행된 병호시비의 중요한 이론적 근거가 되었던 것으로, 향후 정재학파의 이론적 토대에 중요한 영향을 끼쳤다. 『계호학적』은 이황의 도통이 이상정에게 있다는 사실을 밝히기 위해 이상정의 어록과 문집 내용을 발췌하여 이황의 입장과 비교할 수 있도록 편집한 책이다. 『근사록』과 같은 편집체계를 통해 이상정의 철학이 이황과 완전하게 일치한다는 사실을 드러내려고 했던 것이다. 이에 비해 『이학집변』은 퇴계학의 정통성을 공고히 하기 위한 작업으로서의 성격을 가지고 있다. 이단에 대한 강한 비판을 통해 주자학 내에서의 퇴계학 정통성을 공고히 하려고 했던 것이다. 이와 같은 류건휴의 작업은 당시의 시대적 상황 속에서 ‘도통 확립의 필요성’과 이단 비판을 통한 ‘정학正學 보존의 노력’에 따른 것으로, 이를 통해 우리는 후기 영남학파의 인물들이 무엇을 중심으로 생각하면서 살아갔는지를 잘 알 수 있다. 정치적으로 이미 중앙으로부터 소외된 상태에서 그들 스스로의 자긍심과 자부심을 만들어 내고 있으면, 동시에 스스로 주자학적 정통에서 있음을 밝힘으로써 학문적인 우위성을 확보하려는 노력의 일환인 것이다. 더불어 기호학파로부터 받을 수 있는 조금의 의심에 대해서도 철저하게 불식시켜 나감으로써, 자신들 학문의 정통성을 드러내려고 했던 것이다. The purpose of this essay is to examine cognizance of 'taotung(道統: Legitimate Transmission of the Orthodoxy)' and heresy of late Yeungnam School, focused on Ryu, Geon-Hyu's "Gyeho-hakjeok(溪湖學的)" and "Yihak-jipbyeon(異學集辨)", which took the lead in Byungho Dispute(屛虎是非) in Ho faction of the early 19th century. Specially, for the next, these books affected theoretical foundation of Jeongjae School, become theoretical foundation of ByungHo Dispute which is gone on problem of whom the main line of descent of Lee Hwang is continued. Geyho-hakjeok is the book which we can compare to standpoint of Lee Hwang extracting contents of collection of works and quotations of Lee, Sang-Jeong by the book, to define the fact there is the main line of descent of Lee Hwang in Lee, Sang-Jeong. Through a system of edit like Keunsarok(『近思錄』), we can see that philosophy of Lee, Sang-Jeong perfectly correspond with it of Lee Hwang. In comparison, Yihak-jipbyeon has character as work for solidifying legitimate of Toegye's Philosophy. It is to solidify legitimate of Toegye's Philosophy in Zhuxi Studies through strong criticism about heresy. These works of Ryu, Geon-Hyu is caused by 'effort of preservation of Righteousness Philosophy(正學)' through 'necessity of establishing Taotung' and criticism of heresy, on this wise, we can see about what persons of Yeungnam School thought and lived. They make own self-esteem and pride in politically a shunned situation from the central government, at the same time, this is part of effort to secure scientific superiority, by defining that which is on legitimacy of Zhuxi Studies; besides, they was going to reveal legitimacy of own science, by eliminating a little suspicion from kiho School(畿湖學派).

This study was conducted by the slump test and the consistency test of the cement mixed soil which is soil mixed with cement to investigate and estimate the difficulty degree of work and the proper water content. So I would like to present the fundamental data that establish the work standard of the cement mixed soil. In conclusion, in this study the slump value of the cement mixed soil increases over-all according to the increase of the water content although it has a little difference of the increase range and it is smaller than one of the soil. It is estimated that the aggregating and throwing work of the cement mixed soil which is mixed with 6% and 9% cement would be fine when it has the $25%{\sim}27%$ water content and the wall plastering work is the $30%{\sim}32%$ and the floor plastering work is the $30%{\sim}35%$ and the flowing and pouring work is the $40%{\sim}42%$ water content as well as the mold compacting work is the 20%.

본 연구는 불소함유 접착테잎의 법랑질 침식 예방효과를 평가하기 위해건강한 소의 치아를 절단하여 아크릴 주형에 매몰하고 정중선에 홈을 형성하여 대조면과 불소 제제를 도포할 실혐면으로 나누었다. 시편을 무작위로 18개씩 4군으로 나누었다. 1군은 APF gel를 도포하고, 2군은 불소 바니쉬를 도포하였으며, 3군과 4군은 5% NaF를 각각 첨가한 methyl cellulose와 poly vinyl alcohol 테잎을 부착하였다. 시편을 콜라에 5분, 증류수에 10분씩 6회 번갈아 처리하며 5일 동안 반복하였다. 시간 경과에 따라 표면미세경도를 측정하고 5일후 각 시편을 절단하여 침식병소의 깊이를 측정하여 다음과 같은 결과를 얻었다. 1. 표면미세경도 값은 5일째만 제외하고 2군, 3군, 4군의 실험면이 각각의 대조면에 비해 컸다 (p<0.05). 2군, 3군, 4군의 실험면 역시 5일째만 제외하고 1군의 실험면에 비해 표면미세경도가 컸다 (p<0.05). 3군과 4군 사이에는 표면미세 경도의 유의한 차이가 없었다(p>0.05). 1군의 실험면과 대조면은 표면미세경도의 유의차가 없었다(p>0.05). 2. 침식병소의 깊이는 2군, 3군, 4군의 실험면이 각각의 대조면에 비해 컸다(p<0.05). 2군, 3군, 4군의 실험면은 1군의 실험면에 비해 침식병소의 깊이가 얕았다 (p<0.05). 2군, 3군, 4군의 실험면 사이의 침식병소의 깊이는 유의차가 없었다(p>0.05). 상기 결과로 보아 새로 개발된 불소함유 접착테잎은 기존의 불소 바니쉬와 같은 법랑질 침식 예방효과가 분명하게 나타나, 법랑질 침식에 감수성이 높은 어린이 환자에게 임상적인 예방법으로서 활용할 수 있는 가능성이 높다고 사료된다. This study examined the effect of adhesive tape supplemented with sodium fluoride on the prevention of dental erosion in vitro. Sound bovine tooth samples were selected and divided randomly into the following 4 groups according to the material treatments: group 1, APF gel; group 2, fluoride varnish; and groups 3 and 4, fluoride tape supplemented with 5% NaF in either a methyl cellulose or poly vinyl acetate carrier, respectively. All specimens were submitted to alternate cycles of acid exposure in a cola beverage (pH 4.3) and artificial saliva for $6\;{\times}\;5\;min/day$ over a 5 day period. The micro-hardness was recorded each day and the lesion depth was measured after 5 days. The micro-hardness of the experimental sides of groups 2, 3 and 4 were significantly higher than that of their control sides and the experimental side of group 1 during the experimental period (p<0.05) except on the 5th day. The enamel surfaces of treatment groups 2, 3 and 4 showed significantly higher resistance to mineral loss in terms of the erosion depth (p<0.05) than group 1 and their control sides. There was no statistically significant difference among group 2, 3 and 4, indicating that the fluoride varnish and tapes produce similar results. Fluoride adhesive tapes are effective in reducing the progression of erosion and can be recommended for young patients who are more susceptible to dental erosion.

정확한 복사 관측자료는 기후 및 날씨뿐만 아니라 해양과 건축 및 농 축산 분야 등 중요하게 활용된다. 특히 이어도와 같은 종합 해양과학기지는 주변 환경에 의한 복사 반사 효과를 최소화할 수 있기 때문에 이상적인 관측소로 평가되며 여기서 생산되는 자료는 복사관측의 기준 자료가 될 수 있다. 또한 BSRN (Baseline Surface Radiation Network) 등 세계복사관측그룹 가입을 위한 필수 장비들(전천과 직달 및 산란 일사계 등)을 갖추고 관측소 환경을 개선할 경우 전 세계적인 중요 관측소로 부각될 수 있는 여건을 갖추고 있다. 이어도 종합해양과학기지는 2004년 11월부터 일사계 관측을 수행해 왔고 이 연구에서는 2005년 1월 1일부터 2015년 12월 31일까지의 자료를 분석하였다. 이 연구 기간에 이어도의 일평균 일사량은 $-3.80W/m^2/year$로 감소하였고 그 이유는 자연적 원인 이외에 관측장비의 센서 반응도 감소 효과가 포함되어 있기 때문이다. 즉 이어도 종합해양과학기지의 경우 정밀한 복사 관측 자료를 생산하기 위해서는 관측소 환경 개선뿐만 아니라 관측장비 및 자료 보정이 요구된다. 그리고 한반도의 대기 청정도와 국민 건강을 크게 위협하고 있는 중국발 황사와 미세 먼지는 전 세계 과학자들의 중요 관심 대상이기 때문에 이어도뿐만 아니라 신안 가거초 및 옹진 소청초 종합해양과학기지 복사 관측자료를 통한 공동 대응 근거 마련이 필요하며 그에 따라 이들 복사관측소 환경 및 장비 개선 그리고 관측자료 정확성 향상 계획 수립이 시급하다. The radiation observation data will be used importantly in research field such as climatology, weather, architecture, agro-livestock and marine science. The Ieodo Ocean Research Station (IORS) is regarded as an ideal observatory because its location can minimize the solar radiation reflection from the surrounding background and also the data produced here can serve as a reference data for radiation observation. This station has the potential to emerge as a significant observatory and join a global radiation observation group such as the Baseline Surface Radiation Network (BSRN), if the surrounding of observatory is improved and be equipped with the essential radiation measuring instruments (pyaranometer and pyrheliometer). IORS has observed the solar radiation using a pyranometer since November 2004 and the data from January 1, 2005 to December 31, 2015 were analyzed in this study. During the period of this study, the daily mean solar radiation observed from IORS decreased to $-3.80W/m^2/year$ due to the variation of the sensor response in addition to the natural environment. Since the yellow sand and fine dust from China are of great interest to scientists around the world, it is necessary to establish a basis of global joint response through the radiation data obtained at the Ieodo as well as at Sinan Gageocho and Ongjin Socheongcho Ocean Research Station. So it is an urgent need to improve the observatory surrounding and the accuracy of the observed data.

Objective : Insomnia is the disorder of initiation or maintenance in sleeping that results in daytime sleepiness and dysfunction, and it arises from multiple psychological, physiological and environmental factors. A number of stroke patients suffer from insomnia are classified as sleep disorder patients with physical illness. In addition, insomnia may have profound deleterious effects on the natural course of stroke. We are to assess the effectiveness of intradermal acupucture on stroke combined with insomnia. Methods : We recruited hospitalized patients with insomnia after stroke. Then, the subjects were allocated into a treatment group and a control group by randomization. The treatment group received intradermal acupuncture therapy at He-7(神門), EH-6(內關) correctly. However in control group, intradermal acupuncture were just attached to He-7(神門), EH-6(內關) without insertion. Treatment over time at first day and second day a various indexes were repeatedly checked such as sleep latency, total sleep time, sleep quality, condition on awakening, ability of concentration, morning sleepiness, Insomnia Severity Index, and Athens Insomnia Scale. In the second analysis, we divided the treatment group into a response and a non-response group by their response to intradermal acupuncture. With the acupuncture treatment, accompanied symptoms were checked Results : Among thirty two subjects, two of them were dropped out: One complained the pain from needle insertion, and the other underwent the change of his herbal medication. At baseline investigation with the residual 30 subjects, the control and the treatment group were assessed to have an equal comparability. In the treatment group, sleep latency, total sleeping time, a number of awakenings, sleep quality and ability of concentration showed improvement significantly compared with the control group. The non-response Group showed symptoms such as nausea and halitosis, belching and acid regurgitation, abundant expectoration, while Responder Group showed palpitation, oppressed feelings in chest and sleep disorder. Conclusions: The result of this clinical study suggests that the intradermal acupuncture at He-7(神門), EH-6(內關) is one of the effective treatments for the insomnia after stroke.

Microsurgical transthoracic extrapleural approach for thoracic discectomy in three cases were modified and simplified in order to achieve better exposure of ventral extradural space than posterolateral extrapleural(lateral extracavitary) approach and less pulmonary complications than transthoracic transpleural approach. These approaches were optimized by microscope and video-assistance. Surgery was followed by clinical improvement in all patients. The results of treatment seem to support the use of these modified techniques as adequate surgical treatment of thoracic disc herniations without any complications.

Recently, block-based transforms, like discrete cosine transform (DCT), have been widely used in image and video coding standards, but block-based transforms have a weak point with blocking effect. However, the integer lapped orthogonal transform (ILOT) is a tool for block-based coding with bases functions that overlap near blocks, so it has a strong point against blocking effect. Although it has slightly higher arithmetic complexity than the DCT, the coding gain is significantly higher with much less blocking artifacts. This paper introduces the integer lapped orthogonal transforms and discrete cosine transform. And we compare the performance of DCT with ILOT which is proposed a new efficient method for image coding applications.

In this paper, an algorithm is presented to recognize road based on unpaved test courses image. The road images obtained by a video camera undergoes a pre-processing that includes filtering, gray level slicing, masking and identification of unpaved test courses. After this pre-processing, a part of image is grouped into 27 sub-windows and fed into a three-layer feed-forward neural network. The neural network is trained to indicate the road direction. The proposed algorithm has been tested with the images different from the training images, and demonstrated its efficacy for recognizing unpaved road. Based on the test results, it can be said that the algorithm successfully combines the traditional image processing and the neural network principles towards a simpler and more efficient driver warning or assistance system.

Ruthenium CMP에서 Cerium Ammonium Nitrate와 알루미나 연마 입자가 연마 거동에 미치는 영향

이상호,이승호,강영재,김인권,박진구,Lee, Sang-Ho,Lee, Sung-Ho,Kang, Young-Jae,Kim, In-Kwon,Park, Jin-Goo 한국전기전자재료학회 2005 전기전자재료학회논문지 Vol.18 No.9

Cerium ammonium nitrate (CAN) and nitric acid was used an etchant and an additive for Ru etching and polishing. pH and Eh values of the CAN and nitric acid added chemical solution satisfied the Ru etching condition. The etch rate increased linearly as the concentration of CAN increased. Nitric acid added solution had the high etch rate. But micro roughness of etched surfaces was not changed before and after etching, The removal rate of Ru film was the highest in $1wt\%$ abrasive added slurry, and not increased despite the concentration of alumina abrasive increased to $5wt\%$. Even Ru film was polished by only CAN solution due to the friction. The highest removal rate of 120nm/min was obtained in 1 M nitric acid and $1wt\%$ alumina abrasive particles added slurry. The lowest micro roughness value was observed in this slurry after polishing. From the XPS analysis of etched Ru surface, oxide layer was founded on the etched Ru surface. Therefore, Ru was polished by chemical etching of CAN solution and oxide layer abrasion by abrasive particles. From the result of removal rate without abrasive particle, the etching of CAN solution is more dominant to the Ru CMP.

Objectives : Among the various types of minimally invasive spine surgeries, thoracoscopic surgery is becoming more widely accepted and increasingly utilized. This report delineates our clinical experience using thoracoscopy to resect herniated thoracic discs in 16 patients who suffered from myelopathy or intolerable radiculopathy. Patients and Methods : Between Mar. 1997 and Sep. 1999, 16 consecutive patients underwent thoracoscopic discectomy for treatment of herniated thoracic discs. There were 12 men and 4 women(mean age 43.5 years ; range 18-61 years). Eleven patients presented with myelopathic signs and symptoms from spinal cord compression and 5 patients had incapacitating thoracic radicular pain without myelopathy. The surgical level was varied between T3 and T12. The pathology of specimen were 11 hard discs and 5 soft discs herniations. Thoracoscopic techniques were performed with long narrow spine instruments and high speed drill through 3 or 4 ports under one lung ventilated general anesthesia. During the operation three patients were converted to open thoracotomy due to intolerable one lung ventilation, excessive bleeding and inadequate operation field. The mean operation time was 264min.(range : 100-420min.), and postoperative mean admission period was 11 days. Results : Clinical and neurological outcomes were good in all patients(mean follow-up period 20 months). Among the eleven myelopathic patients, 8 improved neurologically, and 3 stabilized. Among the five radiculopathic patients, 4 recovered completely and no patient had worsened. Postoperative complications were pleural effusion in one case, intercostal neuralgia in one, delayed hemopneumothorax in one, prolonged air leakage in one and pneumonia in one case. Conclusions : Thoracoscopic discectomy needs a steep learning curve to be familiar to anatomical space and handling of endoscopic instruments. However, it is technically feasible and can be effectively performed with acceptable results.
