  • 관절경술의 발달과 반월상 연골판의 기능적 중요성이 강조됨에 따라 반월상 연골판 봉합술은 나날이 발전 되어왔다. 그러나 종래의 기법들은 특별한 기구뿐 아니라 신경, 혈관, 연부조직의 손상을 방지하기 위하여 과다한 피부 절개가 필요하거나, 봉합사 매듭이 관절면에 존재하므로 잠재적인 연골손상의 위험성을 가지고 있었다. 이에 저자들은 spinal needle과 nylon loop를 이용한 변형된 outside-in 기법을 소개하고자 하며, 변형된 outside-in 기법은 안정적이고 간단한 봉합이 가능하면서도 별 도의 피부절개가 필요 없는 장점을 가지고 있다.

  • 전방십자인대 재건술에 있어서 최근 가장 각광받고 있는 개념은 해부학적 전방십자인대 재건술이다. 경경골 술식을 이용한 고전적인 방법에 비하여 해부학적 재건술을 위해서 경골터널은 이전보다 전방으로 이동하며 대퇴터널은 낮고 비스듬한 방향으로 만들게 된다. 따라서 낮고 비스듬한 해부학적인 위치의 대퇴터널을 만들기 위하여 전내측 도달법을 통한 술식(anteromedial portal technique), outside-in 술식, 그리고 변형된 경경골 술식(modified transtibial technique) 등이 시행되고 있다. 각각의 방법은 장단점이 있어 술자의 선호도, 경험, 사용 가능한 기구 및 이식건의 선택 등에 따라 선택된다.

  • Since the development of Bubble Image Velocimetry (BIV) technique as the complementary technique of Particle Image Velocimetry (PIV), the application of digital imaging technique in the field of hydraulic and coastal engineering increased rapidly. BIV works very well in multi-phase flow (air-water) flows where the PIV technique doesn't. However, the velocity field obtained from BIV technique often resulted in a velocity vector on the outside of the flow (false velocity) since the Field of View (FOV) usually not only cover the air-water flow but also the area outside the flow. In this study, a simple technique of post processing velocity field was developed. This technique works based on the average of the pixel value in the interrogation area. An image of multi-phase flow of wave overtopping was obtained through physical experiment using BIV technique. The velocity calculation was performed based on the similar method in PIV. A velocity masking technique developed in this study then applied to remove the false velocity vector. Result from non-masking, manually removed and auto removed false velocity vector were presented. The masking technique show a similar result as manually removed velocity vector. This method could apply in a large number of velocity field which is could increase the velocity map post-processing time.

  • Hair style was mean of visual symbol that display position or wealth about human life. Also, have spoken for cultural value as human body plastic art that speak for the age. I wished to study about modeling of hair style and interrelationship of color by analyzing systematically laying stress on color through contest creation work consisted in beauty art congress. Urpose of this study is as following. First, examines domestic' outside great council work head change by era, and studies Hair Work's change in work head. Second, Hair Color's change that appear in domestic' outside contest work head studies effect that get in work. Method of study runs parallel literature study and supporting research, utilized domestic' outside literature, connection paper, magazine, picture data etc. To literature study, and work picture data examined laying stress on work that is choosesed picture dataworld beauty use association (OMC) data etc. that appear in domestic' outside beauty art magazine to examine closely specification and stability of beauty art game style and participates in domestic and world beauty art contest. In this study, domestic' characteristic, and effect that collar gets in work head of collar that collects outside contest participating in an athletic contest hair style by ($1981{\sim}$until present) by year and appears in contest work head and in work since analyzing study forward $2007{\sim}2008$ year direction of collar. First, stream of whole color of the 1980s Brown gave highlight color point partially to basis, and was consisted of creative style and do Gold base color on the whole in Hair by Night item. Second, various Hair color was popularized in the 199Os, and Tuton's color appeared in beauty art game work, and I contributed to improve technique that step-up gradation color appears and does technique to highlight in neon orange in creative style and Hair by Night item by entrance on the stage of neuter gender color.

  • A probe type fiber-optic sensing techique for electric current measurement is applied in this paper. The technique is based on the Faraday effect which meaning is that polarization state of light is rotated by magnetic field. In experiment, test wire is located at inside and outside of the probe to be measured. The experimental results prove not only linear property, but also polarization rotation property according to the distance from outside of probe.

  • If there are metals located in the X-ray scanned object, a point outside the metals has its range of projection angle at which projections passing through the point are disturbed by the metals. Roughly speaking, this implies that attenuation information at the point is missing in the blocked projection range. So conventional projection completion MAR algorithms to use the undisturbed projection data on the boundary of the metaltrace is less efficient in reconstructing the attenuation coefficient in detailed parts, in particular, near the metal region. In order to overcome this problem, we propose the algebraic correction technique (ACT) to utilize a pre-reconstructed interim image of the attenuation coefficient outside the metal region which is obtained by solving a linear system designed to reduce computational costs. The reconstructed interim image of the attenuation coefficient is used as prior information for MAR. Numerical simulations support that the proposed correction technique shows better performance than conventional inpainting techniques such as the total variation and the harmonic inpainting.

  • The Nuclear containment building is a main safety-related structure that performs shielding and conservation functions to prevent highly radioactive materials from leakage to the outside environment in the case of various environmental conditions and postulated accidents. The containment building contains a reactor, steam generator, pressurizer, tank, reactor coolant system, auxiliary system and engineering safety system, and is designed so that highly radioactive materials above the limits specified in 10 CFR 100 do not escape to the outside environment in the case of LOCA(Loss of Coolant Accident) for instance. The containment metal liner plate(CLP) is a carbon steel plate with a nominal plate thickness of 6 mm, which functions as a mold for the wall and dome of the containment building when concrete is filled, fulfills airtightness to prevent leakage of seriously radioactive materials. In recent years, backside corrosion was found on the liner plate in some domestic nuclear power plants. The main cause of backside corrosion was unfilled concrete. In this paper, an inspection technique of assessing filling suitability for CLP backside concrete is developed. Results show that the validity of inspection technique for CLP backside concrete using vibration sensor is successfully verified.
