  • A wide variety of deformities can occur following repair of the cleft lip. Especially, cleft lip nasal deformities offer the severe psychologic, esthetic, and functional impairment. We must restore the deformities of alar cartilge, nasal tip, septum, columella, or pyriform aperture. The authors reconstructed the cleft lip nasal deformities using with the alar cartilage rearrangement, postauricular cartilage graft, and/or columellar lengthening. The 3 case reports are presented.

  • 차량에 연결된 ECU 개수의 증가는 CAN 버스 점유율을 증가시킬 뿐만 아니라 메시지 전송오류 확률의 증가를 초래한다. CAN 데이터 전송 시간은 CAN 프레임의 길이에 비례하기 때문에 프레임의 길이를 줄이게 되면 효율적으로 CAN 버스로드와 오류확률을 감소시킬 수 있다. 본 논문에서는 CAN 메시지의 길이를 단축시키기 위해서 비트재배열과 Data Length Code (DLC)를 이용한 압축 방법을 제안한다. 실제 차량 주행에서 얻은 데이터로 제안한 알고리즘을 시뮬레이션 해본 결과, 기존의 방법에 비해 최대 54%까지 CAN 데이터가 더 압축됨을 확인하였다.

  • For reducing DFC(Dynamic False Contour), we propose a new PDP driving method by rearrangement of sub-fields. The proposed method constructs a frame using 16 sub-fields for expressing 256 gray levels. Although the number of sub-fields increases, the display time increases compared to the conventional 8 sub-fields driving method. This increase in display time is achieved by properly using both selective writing and selective erasing for each sub-field.

  • Based on the co-linearity in the Triticeae, comparative RFLP analysis of 2M chromosome of Ae. comosa Sibth et Sm. was performed with 2MS and 2M additional lines of Triticum aestivum L. cv. Chinese Spring. Among the wheat RFLP probes conserved in the short arms of wheat chromosome 2, those above psr912 were located on the long arms of 2M in Aegilops comosa. The rest probes on the short arm and all the probe sequences on the long arm of group 2 chromosome in wheat were conserved on the equivalent chromosomal position in Aegilops comosa. So, it is apparent that some chromosomal segment from the short arm had been transferred to long arm while reconstructing 2M chromosome relative to wheat chromosomes. The break-point was located between psr912 and psr131 of the short arm. This rearrangement of chromosome 2M might be a molecular evidence of the M genome speciation from an ancestral type.

  • The predominant sintering mechanisms of low firing temperature ceramic substrate which consists of borosilicate glass containing alumina as a filler are the rearrangement of alumina particles and the viscous flow of glass powders. In this system, sintering condition depends on the volume ratio of alumina to glass and on the particle size. When the substrate contains about 35 vol% alumina filler and the average alumina particle size is 4 $\mu\textrm{m}$, the best firing condition is obtained at the temperature range of 900∼1000$^{\circ}C$. The extensive rearrangement behavior occurs at these conditions, and the optimum sintering condition is attained by smaller size of glass particles, too. The formation of cristobalite during sintering causes the difference of thermal expansion coefficient between the substrate and Si chip. This phenomenon degradates the capacity of Si chip. Therefore, the crystallization should be prevented. In the alumina filled borosilicate glass system, the crystallization does not occur. This effect may have some relation with aluminum ions in alumina. For aluminum ions diffuse into glass matrix during sintering, functiong as network former.

  • Anaplastic lymphoma kinase (ALK) rearrangement, is a kind of driver mutation, accounts for 3%-5% of non-small cell lung cancer (NSCLC). NSCLC patients harboring ALK fusion genes have distinct clinical features and good response to ALK inhibitors. Metastasis from lung cancer to the ovary has rarely been known. We report a case of a 54-year-old woman with bilateral ovarian metastases from ALK rearranged NSCLC. She underwent bilateral salpingo-oophorectomy for ovary masses, which were progressed after cytotoxic chemotherapy although primary lung mass was decreased. Histopathological examination of the ovary tumor showed characteristic adenocarcinoma patterns of the lung and ALK rearrangement.

  • Fluorescence in situ hybridization (FISH) with the DNA probe for human chromosome 4 was used to analyse in vitro radiation induced chromosome rearrangement in peripheral lymphocyte. Translocations, dicentrics, acentrics and color junctions involving the painted chromosome were scored according to the Protocol for Aberration Identification and Nomenclature Terminology (PAINT) system. The frequency of chromosome rearrangements including reciprocal translocation, dicentric, acentric fragment and color junction increased with radiation dose. The frequency of dicentric chromosome reduced by the fixation time following irradiation, whereas that of translocation was relatively persistent. The applicability of FISH for scoring stable translocation for biological dosimetry was demonstrated.
