Two cases of immediate reconstruction using sternocleidomastoid myocutaneous flap after modified neck dissection and resection of the primary lesions are presented. One patient had a squamous cell carcinoma at the left mandibular posterior gingiva and adjacent buccal cheek area. The other had a verrucous carcinoma at the right floor of mouth from the retromolar pad to the right mandibular lateral incisor and the lateral border of tongue. There are two approaches for the use of sternocleidomastoid muscle. The superiorly based flap is pedicled by the occipital and superior thyroid artery. The inferiorly based flap is pedicled by the superior thyroid and suprascapular artery. We used superiorly based flap for the reconstruction of the anterior floor of mouth and inferiorly based flap for the posterior floor of the mouth and oropharynx. The patients had no special physiotherapy after surgery, however they are able to open their mouths within normal limit and have normal masticatory and swallowing function.

Recently, the necessity of developing the load and resistance factor design(LRFD) for soft ground improvement method has been raised, since the limit state design is requested as international technical standard for the foundation of structures. In this study, to develop LRFD codes for foundation structures in Korea, target reliability index and resistance factor for static bearing capacity of driven steel pipe piles were calibrated in the framework of reliability theory. The 16 data(in Gwangyang) and the 57 dada(Korea Institute of Construction Technology, 2008) sets of static load test and soil property tests conducted in the whole domestic area were collected along with available subsurface investigation results. As a result, to prepare the introduction of the LRFD from international technical standard, considering the nature of Korea a resistance coefficient from working stress design method was suggested. We created the foundation of the resistance factor design. The result from this research will be the useful information for developing various foundation and soil structure under LRFD.

Heat analysis of the plate type and wave type heat sink were carried out by using computational simulation. The heat resistance and air flow of two heat sink models were analysed according to natural and forced convection condition and positions of fan. When a fan was at the position of z-axis and y-axis in forced convection, the heat resistances of plate type heat sink were $0.17^{\circ}C/W$, and $0.28^{\circ}C/W$ respectively. In the case of wave type heat sink, they were $0.18^{\circ}C/W$ and $0.53^{\circ}C/W$. As the air flow velocities were averagely $0.386\;m/s\~3.269\;m/s$, air flow velocity of plate type heat sink was faster than that of wave type. In this experiment, it was observed that the plate type heat sink showed a good ability of heat radiation comparing with wave type one.

황해 중동부 해역 ($36^{\circ}00'N{\sim}36^{\circ}45'N$,$\;125^{\circ}00'E{\sim}125^{\circ}45'E$)에 분포하는 퇴적층을 대상으로 획득한 고해상 탄성파탐사자료(에어건, 스파커, SBP)와 심부 시추시료(YSDP 105, ${\sim}$64m 깊이)의 종합분석에 따라, 연구 해역의 층서모델을 설정하고 탄성 -음향 모델링을 수행하였다. 층서모델은 탄성파${\cdot}$암${\cdot}$시 층서 단위들을 비교 분석하여 각 지층단위의 음향학적 특성, 퇴적과정, 생성시기를 규명하였다 또한 단위층 형성과정을 해수면 변동과 관련지어 순차층서를 복원하였다. 각 순차층은 육성 또는 천해성 기원이며 조립질의 저해수면 퇴적계와 조석 기원 세립질의 해침-고해수면 퇴적계로 구성되어 있다. 탄성-음향 모델링의 매개변수 산출을 위해, 0.S~90 cm 심도 간격으로 측정된 시추코아의 121 개 평균입도 자료를, Hamilton의 회귀식과 퇴적심도에 따른 변화구배를 이용하여, 전밀도(bulk density)값과 종파속도값으로 변환${\cdot}$계산하였다. 외삽${\cdot}$보정된 121 쌍의 전밀도${\cdot}$종파속도 물성값은 설정된 층서모델에서 제시된 단위층 별로 평균하여 각 단위층의 대표값으로 산출하였다. 퇴적층 내의 탄성-음향 전파 모델링을 위해, 층서모델의 각 단위층에 전밀도와 종파속도의 대표값을 입력 매개변수값으로 부여한 후, 층서 구성 단위층들을 유한요소격자로 분해하였다. 파선추적법의 컴퓨터 모델링 결과, 탄성-음향의 전파는 층서모델을 구성하는 단위층 경계면의 불규칙성과 저속도층의 다수 존재에 의하여 매우 복잡한 음경로를 보이며, 음원의 위치에 따라 탄성-음파의 암영대가 달리 존재함을 확인하였다. 것으로 보아 층 2는 고에너지환경에서 형성되었음을 시사한다. 또한 층 2에서 Al의 증가는 쇄설기원 물질의 유입에 의한 것으로 추정된다. 플라이오세 이후에 형성된 층 1은 치밀한 조직을 보이며, 형성 이후 속성작용을 받지 않았다.선택적으로 분해되는 것으로 여겨진다.두냔 tsuchigae, S. nigripinni morii, M. jeoni, C. splendidus, P. koreanus, C. lutheri, I. koreensis, C. herzi, R. brunneus 등으로 본 종들의 서식 상태는 하천의 오염 정도 및 하천개수와 직접적인 관계가 있으므로 어류서식 환경을 유지시키기 위해서 보다 적극적인 하천 수질관리의 대책과 방안이 수립되어야 될 것으로 사료된다.와 운동, H-R도상에서의 별의 특성과 진화 등이다. 탐구 과정에 대한 학생의 성취도는 비교적 높으므로 이해도가 상대적으로 낮은 영역에 대해 학생의 오답 유형을 참고하여 기본 개념 지도에 보다 관심을 기울일 필요가 있다.Cr은 FW에서 전반적으로 감소하는 경향을 보였지만 SW에서는 실험 초기에 감소하다 24시간 이후에는 증가 후 일정한 양상을 보였다. Pb은 FW에서 전반적으로 감소했지만 SW에서는 초기에 급격히 증가 후 다시 급격히 감소하는 양상을 보였다 Pb 또한 Cu, Cd, As와 마찬가지로 SW1&2에서 제거속도가 가장 빠르게 나타났다. FW 상층수 중 Hg는 시간에 따라 급격히 감소했고, 제거속도는 Fw5&6에서 가장 느렸다. 이러한 결과에 근거할 때 벼가 자라고 있고 이분해성 유기물이 풍부한 FW1&2, FW3&4 토양과 상층수에서는 유기물의 분해 활동이 활발하였지만, 벼가 경작되지 않는 FW5&6과 SW 에서는 유기물이 상대적으로 결핍되어 유기물의 분해활동이 적었을 것으로 판단된다. 한편, 수조에 인위적으로 유기물을 첨가한 경우 박테리아 세포 According to analyses of high-resolution seismic profiles (air gun, sparker, and SBP) and a deep-drill core(YSDP 105) in the mid-eastern Yellow Sea, stratigraphic and geoacoustic models have been established and seismo-acoustic modeling has been fulfilled using ray tracing of finite element method. Stratigraphic model reflects seismo-, litho-, and chrono-stratigraphic sequences formed under a significant influence of Quaternary glacio-eustatic sea-level fluctuations. Each sequence consists of terrestrial to very-shallow-marine coarse-grained lowstand systems tract and tidal fine-grained transgressive to highstand systems tract. Based on mean grain-size data (121 samples) of the drill core, bulk density and P-wave velocity of depositional units have been inferred and extrapolated down to a depth of the recovery using the Hamilton's regression equations. As goo-acoustic parameters, the 121 pairs of bulk density and P-wave velocity have been averaged on each unit of the stratigraphic model. As a result of computer ray-tracing simulation of the subsurface strata, we have found that there are complex ray paths and many acoustic-shadow zones owing to the presence of irregular layer boundaries and low-velocity layers.

Soybean yellow common mosaic virus (SYCMV) has been recently reported, it has been occurred a lot with Soybean mosaic virus (SMV) and Soybean yellow mottle mosaic virus (SYMMV) in soybean field. SYCMV belongs to genus of Sobemovirus and induced viral symptoms with yellowing, mottle and mosaic. A reverse transcription loop-mediated isothermal amplification (RT-LAMP) method allowed one-step detection of gene amplification by simple procedure and needed only a simple incubator for isothermal template. This RT-LAMP method allowed direct detection of RNA from virus-infected plants without thermal cycling and gel electrophoresis. In this study, we designed RT-LAMP primers named SYCML-F3/B3/FIP/BIP from coat protein gene sequence of SYCMV. After the reaction of RTLAMP, products were identified by electrophoresis and with the detective fluorescent dye, SYBR Green I. under daylight and UV light. Optimal reaction condition was at 63 for 60min and the primers of RTLAMP showed the specificity for only SYCMV tested in this study.

It has been reported several viral diseases in soybean. The occurrence of Bean common mosaic virus and Peanut stunt virus are able to induce severe problem because the main breeding target for viral disease was focused on Soybean mosaic virus. BCMV is a spcies of the genus Potyvirus of the family Potyviridae. BCMV reduces yield by as much as 80% and also adversely affects seed quality in common bean. BCMV has a worldwide distribution because of its high rates 35% of transmission via seeds produced by plants systemically infected prior to bloom. PSV is a species of the genus Cucumovirus of the family Bromoviridae. PSV has been reported to be economically damaging on beans worldwide. Although the virus is reportedly seed transmissible at very low rates, infected plants rarely produce pods with normal viable seeds. The most satisfactory management method of viral diseases such as BCMV and PSV is the use of resistant cultivars and healthy seed. For the overcome of genetic resistance by new virus such as BCMV and PSV, virus diseases monitoring and researches need to study deeply and continually. In this study, we conducted the resistance screen on BCMV and PSV for selection of resistance cultivars. We inoculated on 128 cultivars with PSV and BCMV respectively. These cultivars were classified through pathogenic response such as resistance, necrosis and susceptibility. In addition, 99 and 66 resistant cultivars were confirmed against PSV and BCMV respectively.
