  • 대부분의 과채류가 그러하듯이 신선도는 상품가치 판단기준의 가장 중요한 척도중에 하나이다. 현장에서 생산된 상태로 소비자에게 가장 빠른 유통경로를 통해서 공급되는 것이 가장 바람직하지만, 때로는 그렇지 못하는 경우도 생긴다. 따라서 가능하면 수확, 운반, 저장시에 신선도를 오래 유지할 수 있도록 만드는 것이 여러 가지 측면에서 유리하다. (중략)

  • We report a case of pseudoaneurysm formation after aneurysmal clipping. An aneurysm, which was located on the beginning of orbitofrontal artery, was clipped and wrapped with $Surgicel^{(R)}$ and fibrin glue. Four weeks later, an enlarged aneurysm was detected at the same site on postoperative angiography. We could not find a new aneurysm in the second operation except inflated wrapping region. And clip had been slipped from the original aneurysmal neck. So we concluded that a new aneurysm was a pseudoaneurysm made with surgicel and fibrin glue. And it had been formed from continuous minor leakage caused by slipped clip.

  • A new mesh reconstruction scheme for approximating a surface from a set of unorganized 3D points is proposed. The proposed method, called a shrink-wrapped boundary face (SWBF) algorithm, produces the final surface by iteratively shrinking the initial mesh generated from the definition of the boundary faces. SWBF surmounts the genus-0 spherical topology restriction of previous shrink-wrapping-based mesh generation techniques and can be applied to any type of surface topology. Furthermore, SWBF is significantly faster than a related algorithm of Jeong and others, as SWBF requires only a local nearest-point-search in the shrinking process. Our experiments show that SWBF is very robust and efficient for surface reconstruction from an unorganized point cloud.

  • This is a study regarding the development of cultural products with applied traditional Saekdong-image. The objective of this study is to develop unique cultural products which combine traditional korean images with modern feel by utilizing traditional Saekdong-image. Saekdong has been an object of deep attachment and regarded as a tool for expressing korean images from ancient times to the present. Chosun dynasty shows a wonderful growth of fashion not only in dress but also in such accessories as patchwork wrapping-cloth and Saekdong, which imply a lot on formation or color arrangement. Approximately 24 pieces of cultural products that can be used in daily life were created using Saekdong, including traffic or credit card cases, name card cases, pouches, coin purses, bags, Vest, teapot wrapping-cloth, brooch. After design plans were made for each works, natural dyes were used to dye(dip dyeing) the fabrics(cotton, silk, linen) by theme. In addition, the increased quality of the products will be a competitive edge in the world market where products compete with no national bounds.

  • Purpose of this study is to investigate structural behavior of the rectangular hollow column with various transverse reinforcement details. Experimental variables are diameter, arrangement details and lateral spacing of cross tie. A total of 66 column specimens have been prepared and tested under axial compressive load. Test results showed that behaviors of column specimens were different depending on the cross tie details. Specimens with cross tie wrapping longitudinal steel and transverse steel have greater strength and ductility than specimens with cross tie wrapping the longitudinal steel.

  • 댁내의 제어 네트워크는 냉장고, 세탁기, 전자레인지 같은 가전제품과 전등, 가스 경보기, 보일러 등에서 제품 고유의 기능을 수행하기 위하여 일반적으로 8Bit 이하의 비교적 저 기능의 마이컴을 채용하고 있으며 각각의 통신을 위한 각 기기 고유의 통신 프로토콜을 가지고 있다. 이렇게 각각 다른 통신 방식으로 인하여 실제적으로 하나의 통합된 댁내 제어 네트워크 구성은 매우 어렵다. 이에 기존 제어기기 각각의 프로토콜을 유지한채 모든 제어기기의 프로토콜을 수용할 수 있는 방법은 새로운 프로토콜을 만들어 기존 기기의 프로토콜을 Wrapping 하는 방법이다. 본 논문에서는 기존 제어기기들의 통신 프로토콜을 Wrapping 할 수 있는 통합 프로토콜을 구현하여 하나의 통일된 제어 네트워크를 구성할 수 있도록 하였다.

  • 단층촬영영상(Tomographic cross-section images)으로부터 임의의 등밀도 표면(iso-density surface)을 재구성하기 위한 새로운 방법을 제안하였다. 이 방법에서는 마칭큐브 알고리즘에 비해 정밀도는 떨어지지만 안정적인 표면을 생성하는 셀경계 알고리즘(Cell-Boundary Method)을 이용하여 초기메쉬를 구하고 이를 표면축소포장(Shrink-wrapping)처리를 통해 정밀한 등밀도 표면을 생성하게 된다. 이는 마칭큐브와 같이 단층영상에서 등밀도 표면을 직접 추출하는 것이 아니라 등밀도점(iso-density Point)을 먼저 추출하고 표면의 모호성이 없는 안정적인 초기메쉬를 이들 방향으로 축소하여 정확한 표면모델링을 가능하게 한다. 이를 통해 마칭큐브에서 발생하는 표면 결정의 모호성이 없이 보다 안정적인 표면을 정확하게 만들 수 있다.

  • The sweet persimmons are producted 227,394 tons per year in Korea. They are preserved at cold storage after wrapping them in packing vinyl to maintain quality. Using conventional handwork, a skillful worker could probably produce only 1,000 packings a day. Hiring many skilled-labors to wrap sweet persimmons in packing vinyl seems to be difficult because of the recent rural crisis. Therefore, it was necessary to be developed for the automated ordering and packing unit that is convenient and laborsaving. This study were summarized as follows : Success rates of 99%, 100%, and 88% were observed for ordering parts, sealing and cutting films, and sealing films in the inlet part, respectively. The time required per 1 cycle was 16 seconds and the developed unit performed 225 cycles an hour. The unit showed an ability of 1,125 pieces per hour. Therefore, the productivity was 10 times greater than that of skillful handwork.

  • An experimental investigation was conducted to examine the feasibility of Carbon Fiber Sheet(CFS), a kind of high strength fiber, for a repair and reinforcement method of concrete structures. The experimental program included tests of flexural beams different in wrapping method and amount of CFS. The beams were subjected to monotonic loading. Although the flexural strength for concrete members increases with wrapping methods of CFS., the reduction factor due to the distribution, amount bond of CFS should be completely examined. This study approached the effectiveness and application of CFS, along with reinforcement effects of CFS on reinforced concrete beams through tests. Test results indicated that the increase in the number of CFS layer caused the increase in strength of beams in strength.

  • Although retrofitting and strengthening reinforced concrete (RC) columns by wrapping fiber reinforced polymer (FRP) composites have become a popular technique in civil engineering, the study on reinforced high-strength concrete (HSC) columns is still not sufficient. The objective of these companion papers is to investigate the mechanical properties of reinforced HSC square columns confined by aramid FRP (AFRP) jackets under concentric compressive loading. In the part I of these companion papers, an experiment was conducted on 54 confined RC specimens and nine unconfined plain specimens, the considered parameters were the concrete strength, the thickness of AFRP jackets, and the form of AFRP wrapping. The experimental process and results are presented in detail. Subsequently, some discussions on the confinement effect, failure modes, strength, and ductility of the columns are carried out.
