사계 김장생의 예학과 사회정치사상

김태완 ( Tae Wan Kim ) 율곡학회 2010 율곡학연구 Vol.21 No.-

김장생은 이이의 학맥을 이어서 기호학파 또는 율곡학파의 문호를 연 인물이다. 그의 학문적 업적은 특히 예학에서 두드러지게 드러난다. 김장생은 이이의 성리학과 송익필의 예학을 계승하여 자신의 예학체계를 완성하였다. 김장생의 예학이론은 『상례비요』, 『가례집람』, 『의례문해』, 『전례문답』의 사부작에 들어 있다. 김장생은 이들 예서에서 자신의 실용적, 합리적, 주체적 예학 이론을 피력하였다. 김장생은 인조반정 뒤 집권한 서인의 정신적 지주로서 새로운 조선의 기틀을 예로써 확립하려고 노력하였다. 당시 점점 심각해지던 사회경제적인 모순에 대해서도 개혁을 시도하였다. 김장생 예학의 특성은 예의 보편성과 현실성의 조화를 이루고 국가전례에서도 종통을 확립함으로써 사적 예와 공적 예를 일관된 정신으로 묶으려고 한 것이다. 김장생은 종법의 확립을 통한 예제질서를 구축하여 인의와 예가 지배하는 사회를 꿈꾸었다. 그런 점에서 김장생의 예학은 조선사회를 새로이 구성하는 기획이었다. Kim Jang-saeng was the most famous scholar who succeeded in following Yi-i(李珥)`s studies and established the Ki-ho Schools or Yul-gok Schools in Cho-seon dynasty. In the Rye-hak(禮學 or a study of Rites), his academic achievements were distinctively demonstrated. He explored Yi-i`s Neo-confucian theory and Song Ik-pil(宋翼弼)`s Rye-hak and accomplished his own system of Rye-hak. His theories of Rye-hak were appeared in Sang-rye bi-yo(喪禮備要), Ka-rye jip-ram(家禮輯覽), Ui-rye mun-hae(疑禮問解) and Jeon-rye mun-dap(典禮問答) of a tetralogy. In the tetralogy, Kim demonstrated his practical, rational, and subjective theories of the Rye-hak. As an ideologue of Seo-in party, which held the political power of Cho-seon after the revolution of the King In-jo, Kim aspired to set up a new political system of Cho-seon in the pursuit of the Rye. He also tried to reform the severe socio-economic problems issues and matters that the Cho-seon was facing in those years. Kim particularly tried to harmonize the universality and peculiarity of Rye and in so doing it, he attempted to combine unify the individual or private with the public sides of Ryes. He also made developed a comprehensively full-fledge theory of Rye for the royal. He dreamt of a society which could had been possibly governed by the In-ui(仁義 or Humanity and Justice) and the Rye. What Kim`s Rye-hak envisioned, therefore, a master-plan of new society of Cho-seon.

김태완,이영철,Kim, Tae-Wan,Lee, Young-Chul 한국정보통신학회 2009 한국정보통신학회논문지 Vol.13 No.7

본 논문에서는 LTCC 다층회로 기술을 이용하여 GSM과 CDMA 대역을 분리 하는 diplexer를 설계 및 제작하여 그 특성을 측정하였다. Diplexer의 집적도를 높이가 위해 3차원 적층형 인덕터와 커패시터를 이용하여 유전율 7이고, 총 6층의 LTCC 기판에 설계되었다. 저역통과 필터에 인덕터와 고역통과 필터에 커패시터를 각각 병렬로 결합하여 두 대역의 주파수 대역의 선택성을 높였다. LTCC표준 공정으로 제작되어진 다이플렉서의 크기는CPW pad를 포함하여 3,450 ${\times}$4,000 ${\times}$694 ${\mu}$m3이다. GSM 대역에서 -1.35 dB 이하의 삽입 손실과 -5.66 dB 이상의 반사 손실, 그리고 CDMA 대역에서는 -1.54 dB 이하의 삽입 손실과 -9.30 dB 이상의 반사 손실의 특성을 나타내었다. In this paper, a diplexer circuit to separate GSM from CDMA band is designed using a LTCC (Low Temperature Cofired Ceramic) multi-layer technology. In order to increase a integration capability of the diplexer, it is designed using 3-dimensional (3-D) multi-layer compact inductor and capacitors in e-layer LTCC substrate with a relative dielectric constant of 7. In order to achieve high selectivity of the bands, a shunt capacitor and inductor are designed in the high-pass filter (HPF) and low-pass filter (LPF), respectively. The size of the fabricated diplexer including CPW pads is 3,450 ${\times}$4,000 ${\times}$694 ${\mu}m^3$An insertion loss (IL) and return loss in GSM band are less than -1.35dB and more than -5.66dB,respectively. In the case of CDMA band, the IL of -1.54dBandRLof above -9.30dBare archived.

Purpose: To report a case of intralenticular triamcinolone complicated by intravitreal triamcinolone acetonide (IVTA) injection. Methods: A 56-year-old man who presented with lens opacity in the right eye following IVTA injection as a treatment for the central retinal vein occlusion with macular edema was referred to our clinic. Results: The visual acuity in his right eye was hand motion, which was not corrected. A slit lamp examination showed that the intralenticular crystalloid powder in the right eye was likely triamcinolone acetonide. Intralenticular crystalloid powder was detected during the phacoemulsification and the posterior capsule of the lens had been already ruptured. Conclusions: Lens opacity can be complicated by IVTA through intralenticular injection of triamcinolone acetonide.

김태완,함형길,Kim, Tae-Wan,Hahm, Hyung-Gil 한국콘크리트학회 2016 콘크리트학회논문집 Vol.28 No.3

본 연구는 다양한 농도의 탄산나트륨($Na_2CO_3$)로 활성화된 대량치환슬래그 시멘트(HVSC)의 초기강도 향상에 관한 연구이다. 보통 포틀랜드 시멘트(OPC)에 대해 고로슬래그 미분말(GGBFS)을 질량의 50에서 90% 치환하였고, 페이스트 믹싱전에 건조한 분말재료를 서로 섞어 두었다. $Na_2CO_3$는 전체 결합제(binder, OPC+GGBFS) 중량의 0, 2, 4, 6, 8 그리고 10%를 혼합하였다. 모든 배합의 물-결합재 비(w/b)는 0.45로 일정하게 하였다. 압축강도, 초음파속도(UPV), 흡수율 그리고 XRD를 초기재령(1일과 3일)에서 실시하였다. V5(50% OPC + 50% GGBFS), V6(40% OPC + 60% GGBFS) 그리고 V7(30% OPC + 70% GGBFS) 시험체에서는 6% $Na_2CO_3$에서, V8(20% OPC + 80% GGBFS)과 V9(10% OPC + 90% GGBFS) 시험체에서는 10% $Na_2CO_3$에서 최고강도가 나타났다. UPV와 흡수율은 압축강도 특성과 유사한 경향을 나타내었다. XRD 분석결과 수화반응생성물질은 CSH 그리고 calcite($CaCO_3$)가 나타났다. 이러한 결과를 볼 때 HVSC 페이스트의 초기강도에는 $Na_2CO_3$의 혼합이 $Na_2CO_3$를 혼합하지 않은 경우와 비교하여 더 좋은 결과를 나타내었다. This report presents the results of an investigation on the early strength development of pastes high volume slag cement (HVSC) activated with different concentration of sodium carbonate ($Na_2CO_3$). The ordinary Portland cement (OPC) was replaced by ground granulated blast furnace slag (GGBFS) from 50% to 90% by mass, the dry powders were blended before the paste mixing. The $Na_2CO_3$ was added at 0, 2, 4, 6, 8 and 10% by total binder (OPC+GGBFS) weight. A constant water-to-binder ratio (w/b)=0.45 was used for all mixtures. The research carried out the compressive strength, ultrasonic pulse velocity (UPV), water absorption and X-ray diffraction (XRD) analysis at early ages(1 and 3 days). The incase of mixtures, V5 (50% OPC + 50% GGBFS), V6 (40% OPC + 60% GGBFS) and V7 (30% OPC + 70% GGBFS) specimens with 6% $Na_2CO_3$, V8 (20% OPC + 80% GGBFS) and V9 (10% OPC + 90% GGBFS) specimens with 10% $Na_2CO_3$ showed the maximum strength development. The results of UPV and water absorption showed a similar tendency to the strength properties. The XRD analysis of specimens indicated that the hydration products formed in samples were CSH and calcite phases.

한국인에서 발생한 사르코이드 포도막염의 임상 양상

Purpose: To investigate the clinical features of Korean patients with sarcoid uveitis. Methods: The medical records of patients with endogenous uveitis who were recruited from the uveitis clinic at Seoul National University Hospital were reviewed. Sex, age at presentation, ocular symptoms and signs, treatment, complications, and the rate of recurrence were analyzed. Results: Of 440 patients with endogenous uveitis, 31 (7.1%) with sarcoidosis were included. The mean age at onset was 54.5 years. Sarcoidosis patients with uveitis tended to be older than those without uveitis (44.1 years). Uveitis was the primary manifestation of sarcoidosis in 16 of 31 patients (51.6%). Anterior uveitis was the most common in terms of the anatomic location of inflammation (54.8%), and posterior involvement (38.7%) was not rare. Systemic corticosteroid therapy was administered to 28 patients (90.3%). Five patients (16.1%) received corticosteroids combined with immunosuppressive agents. Conclusions: Sarcoid uveitis is not a rare etiology of endogenous uveitis. Topical or systemic corticosteroids could control inflammation in most cases, but immunosuppressive agents are needed in a small percentage of patients. Steroids combined with immunosuppressive agents can prevent severe visual losses in such patients. J Korean Ophthalmol Soc 2008;49(9):1483-1490

Bottom Ash의 전기적 특성과 일축압축강도

김태완,손영환,박재성,노수각,봉태호,Kim, Tae-Wan,Son, Young-Hwan,Park, Jae-Sung,Noh, Soo-Kack,Bong, Tae-Ho 한국농공학회 2014 한국농공학회논문집 Vol.56 No.1

The objective of this study is to find the electrical properties of Bottom ash from thermoelectric power plants in Korea. By using Parallel Plate Method, the electrical resistivity and dielectric constant were measured at the frequency from 20 Hz to 10 MHz. Also, unconfined strength test, XRF and sieve analysis were performed for finding the relationship between strength, physiochemical properties and electrical properties. In the result, the change of electrical resistivity and dielectric constant of bottom ash against frequency was similar to that of general soil. The proportion of fine grain in bottom ash had the positive correlation with dielectric constant and negative correlation with electrical resistivity. Chloride and sulfur trioxide were proportional to dielectric constant and the more bottom ash had chloride content, the lower electrical resistivity appeared in bottom ash. Unconfined strength of bottom ashes had a range from 200 kPa to 780 kPa and strength was inverse proportional to electrical resistivity.
