김용성,Kim, Young-sung 국립문화재연구원 2014 헤리티지:역사와 과학 Vol.47 No.2

백제의 능묘는 금강유역으로 천도 후 송산리식의 횡혈식석실묘 ${\rightarrow}$ 남조식의 전실묘 ${\rightarrow}$ 능산리식의 횡혈식석실묘로 변천하였다. 이 변화에서 가장 눈에 띄는 것이 천장 구조의 변화이다. 천장은 궁륭천장(송산리식) ${\rightarrow}$ 터널천장(전실묘와 능산리식 과도기) ${\rightarrow}$ 집지붕천장(능산리식으로 제형, 삼각형, 평천장 세 아류의 형식)으로 변천했다. 이러한 변천과정에서 가장 특징적인 것은 능산리식 횡혈식석실로 이는 백제에서 창출된 특수한 형식이다. 백제의 능묘는 봉분을 중시하지 않아 현저하지 않았다. 이는 개별 능묘를 과시하여 표지하고자 하는 의도보다는 능원의 영역을 중시하는 가족공동체적인 성격이 강화된 것이고 남조의 영향으로 볼 수 있다. 백제의 능원은 백제가 남천한 후 왕가의 능원에서 단독의 독립능원으로 변천한다. 전자는 송산리와 능산리의 능원이고, 후자는 익산의 쌍릉이다. 전자는 완벽한 풍수지리와 함께 남조의 영향으로 볼 수 있고, 후자는 중국이 재통일된 수와 당초의 능원제 영향이다. 왕가의 능원에는 왕릉만 존재하는 것이 아니고 그와 관련된 인물을 배장하였다. 그리고 능원에는 제의시설이 존재했다. 송산리 능원에는 제단이 설치되어 있었는데, 이는 시조묘적인 성격도 가지고 있었을 가능성이 크다. 능산리 능원에는 공동의 능묘에 대해 제의를 시행할 수 있는 노천의 제의 공간이 마련되었고, 이 제의를 담당하면서 선왕에 대한 명복을 빌기 위한 능사가 설치되었다. 이러한 배치나 구조는 신라의 서악동 능원과 아주 유사하다. The royal tombs of Baekje(백제), after the transfer of the capital to the Geumgang(riv)(금강) basin, changed to Songsanri(송산리) style(stone chamber) ${\rightarrow}$ Southern dynastic(남조) style(brick chamber) ${\rightarrow}$ Neungsanri(능산리) style(stone chamber). The most special feature of this process is the change of the ceiling structure. The ceiling had been changed from dome(Songsanri style) ${\rightarrow}$ tunnel ceiling(transition period of brick tombs and Neungsanri style) ${\rightarrow}$ a roof style(is Neungsanri style of three imitate type, trapezoid, triangle, flattened ceiling). The most special feature among this process is Neungsanri style(stone chamber), created especially in Baekje. The royal tombs of Baekje didn't lay stress on the mound, so the mound is not noticeable. It is result that they more stressed on basin of the boundary than showed off individual tomb, and this is count as an element of China Southern dynasty. Boundary of the royal tomb of Baekje, after the transfer of the capital to south, were changed from royal family's boundary to single independent's. Those are Songsanri's and Neungsanri's, these are the pair tombs(쌍릉) of Iksan(익산). That is influence of the Southern dynasty, reflect the theory of divination based on topography completely, this is influence of the China Sui(수) and the early Tang(당) dynasty's system of boundary of the royal tomb. Besides the royal tomb, they also buried a closely related person, in the boundary of the royal tomb. And facilities for memorial ceremony were existed too. An altar was equipped in Songsanri's boundary of the royal tomb, it was seen a kind of character of a sanctuary for progenitor. Neungsanri's boundary of the royal tomb were equipped with an open-aired altar that performed memorial ceremony about communal royal tombs, and also equipped a temple, was needed to pray for the happiness of the dead. This structure and arrangement are very similar to Seoakdong(서악동) of Silla(신라).

Recently, research on cost reduction and efficiency improvement of crystalline silicon(c-Si) photovoltaic(PV) module has been conducted. In order to reduce costs, the thickness of solar cell wafers is becoming thinner. If the thickness of the wafer is reduced, cracking of wafer may occur in high temperature processes during the c-Si PV module manufacturing process. To solve this problem, a low temperature process has been proposed. Conductive paste(CP) is used for low temperature processing; it contains Sn57.6Bi0.4Ag component and can be electrically combined with solar cells and ribbons at a melting point of $150^{\circ}C$. Use of CP in the PV module manufacturing process can minimize cracks of solar cells. When CP is applied to solar cells, the output varies with the amount of CP, and so the optimum amount of CP must be found. In this paper, in order to find the optimal CP application amount, we manufactured several c-Si PV modules with different CP amounts. The amount control of CP is fixed at air pressure (500 kPa) and nozzle diameter 22G(outer diameter 0.72Ø, inner 0.42Ø) of dispenser; only speed is controlled. The c-Si PV module output is measured to analyze the difference according to the amount of CP and analyzed by optical microscope and Alpha-step. As the result, the optimum amount of CP is 0.452 ~ 0.544 g on solar cells.

DRNS용 SRTFR 변환기 설계에 관한 연구

김용성,Kim, Young-Sung 한국정보기술전략혁신학회 2009 情報學硏究 Vol.12 No.2

Residue Number System is used for the purpose of increasing the speed of processing in the many application parts of Image Processing, Computer Graphic, Neural Computing, Digital Signal Processing etc, since it has the characteristic of parallelism and no carry propagation at each moduli. DRNS has the twice RNS Conversion, it is used to decreases the size of the operator in RNS. But it has a week point on the Second Residue to First Residue Conversion time. So, in this paper SRTFR(Second Residue to First Residue) Converter using MRC(Mixed Radix Conversion) is designed to decrease the size of RTB(Residue to Binary) Converter. Since the proposed SRTFR Converter using MRC(Mixed Rdix Convertion) has a pipeline processing. Also, modular operation is applied to at each partitioned SAM(Subtraction and Addition) and MA(Multiplication and addition). In the following study, the more effective design on MA is needed.

We have investigated thermal stability of the mechanical and thermal conductive properties of Cu/STS/Cu 3 layered clad metal lead frame material for a LED device package at different temperatures ranging from RT to $200^{\circ}C$. The fabricated Cu/STS/Cu clad metal has a good thermal stability for the mechanical tensile strength and thermal conductivity of the over 50 $Kg/mm^2$ to the $150^{\circ}C$ and 270 $W/m{\cdot}K$ to the $200^{\circ}C$, respectively. This clad metal lead frame material at a high temperature of $150^{\circ}C$ shows a reinforced mechanical tensile strength by 1.5 times to conventional pure copper lead frame materials and also a comparable thermal conductivity to typical copper alloy lead frame materials.

김용성,배민애,윤구식,Kim, Young-Sung,Bae, Min-Ae,Yoon, Koo-Sik 대한화학회 2001 대한화학회지 Vol.45 No.3

양 밀단에 methacryl기를 함유한 polydimethylsiloxane(PDMS)을 가교제로 하여 poly(N-isopropylacrylamide)(PNIPAAm)을 합성하여 PDMS를 함유한 PNIPAAm을 얻었다. IR, DSC를 이용하여 그것들의 성질을 조사하였으며 DSC 조사결과 PNIPAAm과 PDMS는 각각 분리된 상으로 존재하는 것이 확인되었으며, PNIPAAm의 $T_g$는 PDMS의 함량이 증가하면 약간씩 감소하였다. 또한 온도에 따른 팽윤도를 조사한 결과 PDMS의 함량이 증가하면 팽윤도는 감소하였으나 lower critical solution temperature(LCST)는 큰 변화가 없었다. 수팽윤된 중합체의 DSC 측정결과도 LCST는 PDMS의 함량에 영향을 받지 않는 다는 것을 확인하였다. Poly(N-isopropylacrylamide) (PNIPAAm) containing polydimethylsiloxane (PDMS) was synthesized using PDMS as crosslinking agent, and characterized by IR and DSC. It seems that the copolymer has separated phases, PNIPAAm and PDMS. The $T_g$ of PNIPAAm was decreased in accordance with the increase of PDMS-contents. The swelling behavior of polymer in water was examined with the function of temperature and PDMS-contents as well. The equilibrium swelling ratio of polymer in water was decreased with increasing PDMS-contents, but lower critical solution temperature (LCST) was not significantly affected by the incorporated PDMS-contents.

In this study, borehole records were analyzed to verify the amplification of seismic motion at the soft reclaimed ground before and after the main event of the 1995 Hyogoken Nambu Earthquake at Port Island, Japan. From the analysis, it was shown that the amplification of seismic motion occurred near the soft ground surface (within 30 m below) where confining stress is low. Moreover, it was found that recovery of dynamic soil stiffness at the liquefied ground began gradually 3 hours after the liquefaction and completed in 10 days, when the ground exhibited the same seismic motion characteristics as those before the liquefaction.

Fast Handovers for Mobile IPv6 구현 및 성능 평가

이동 장치의 발전과 인터넷의 급격한 성장에 따라 호스트의 이동성을 제공하기 위해 IETF에서는 Mobile IPv6를 제안하였다. Mobile IPv6는 노드의 위치 및 이동성 관리를 통해 호스트에게 끊김없는 서비스를 제공 하고자 한다. 그러나 Mobile IPv6에서는 노드가 이동하는 동안 데이터 통신을 할 수 없는 시간이 존재하게 되는데 이것을 핸드오버 지연 시간이라 한다. Mobile IPv6는 VolP와 같은 지연 시간에 민감한 트래픽을 지원하기에는 핸드오버 지연 시간이 크다. FM IPv6는 이러한 지연 시간을 줄이고자 제안된 프로토콜로서 두 가지 모드, 즉 predictive모드와 reactive모드가 존재한다. 본 논문에서는 FMIPv6구현을 통해 기존의 MIPv6와의 핸드오버 성능을 실제 테스트베드 네트워크에서 비교 분석하고자 한다. 실험 결과를 통해 reactive FMIPv6가 기존의 MIPv6보다 predictive FMIPv6 가 reactive FMIPv6 보다 더 좋은 성능을 보여준다는 것을 알 수 있다. 그리고 FMIPv6 역시 지연 시간에 민감한 트래픽을 지원하기에는 부족하다는 것을 보여준다.
