Purpose: To report modified technique of inside-out suture in repair of tear of postero medial corner of medial meniscus. Operative technique: Arthroscope is placed through anterolateral portal. Suture hook is delivered through anteromedial portal. By rotating the suture hook, it penetrates the inner portion of the torn meniscus from femoral surface to tibial surface of the meniscus for vertically oriented suture. A PDS suture is delivered through the lumen of suture hook, and the suture hook is withdrawn. The both ends of the suture are retrieved through anteromedial portal by a retriever, either grasper or crochet hook.A Zone-specific cannula is positioned below the inferior surface of the meniscus through anterolateral portal. The Looped Needle designed by the authors is delivered through the lumen of the Zone-specific cannula. The suture end of the tibial surface is placed in the loop of the Looped Needle and pulled out to the surface of posteromedial joint line. The suture end of the femoral surface is pulled out in same manner. A transverse skin incision of 1cm size is made adjacent to pulled out suture and the suture is tied. Discussion: Even though modified inside-out suture technique requires longer operation time than conventional inside-out technique, it provides vertically oriented suture and good tissue coaptation. The authors recommend this modified inside-out suture technique to be good alternative in repairing tear of the posteromedial corner of medial meniscus.

The electronic structures of the potential candidate semiconductor nanoparticles for dye-sensitized solar cell (DSSC), such as $ZnSnO_3$ and $Zn_2SnO_4$, have been investigated by employing X-ray photoemission spectroscopy (XPS). The measured X-ray diffraction patterns show that $ZnSnO_3$ and $Zn_2SnO_4$ samples have the single-phase ilmenite-type structure and the inverse spinel structure, respectively. The measured Zn 2p and Sn 3d core-level XPS spectra reveal that the valence states of Zn and Sn ions are divalent (Zn 2+) and tetravalent (Sn 4+), respectively, in both $ZnSnO_3$ and $Zn_2SnO_4$. On the other hand, the shallow core-level measurements show that the binding energies of Sn 4d and Zn 3d core levels in $ZnSnO_3$ are lower than those in $Zn_2SnO_4$. This work provides the information on the valence states of Zn and Sn ions and their chemical bonding in $ZnSnO_3$ and $Zn_2SnO_4$.

프랑스에서는 사르코지 정부 출범 전후에 여러 가지 개혁 동향들이 발표되어왔다. 프랑스는 오래 전부터 대학제도의 불합리성을 잘 알고 있었다. 20년 전부터 3번에 걸쳐 대학제도개혁을 시도하였으나 번번이 실패한 바 있으며, 지금도 대학의 전반적인 개혁이 시급한 문제로 대두되고 있다. 특히 수요자인 대학생에게 신뢰를 주지 못한 것이 대학의 가장 큰 문제점으로 지적되어왔다. 피용 내각의 고등교육제도개혁 방향을 소상히 살펴보기에 앞서 먼저, 프랑스 정부가 시급히 개혁을 추진하지 않을 수밖에 없었던 이유를 진단해 봄으로써 프랑스 고등교육의 문제점을 심도 있게 관찰해 보도록 한다.

원자력발전소 금속파편감시계통(LPMS : Loose Parts Monitoring System)은 내각재계통 내부에 존재하는 금속파편물을 조기에 탐지하여 관련 구조물 파손을 방지하므로써 불필요한 검사 및 보수로 인한 작업자 방사선 피폭를 최소화하며 원전 안전성 및 경제성을 제고시킨다. 현재 국내 원전에서 가동중인 금속파편감시설비중 영광 1,2호기와 고리 3,4호기에서 운영중인 Westinghouse사의 금속파편감시설비(상품명: Digital Matal Impact Monitoring System)는 70년대에 개발되어 설치된 설비로 기능의 낙후와 장기간 운영에 따른 노후화로 인해 발생될 수 있는 문제점을 방지하고자 하드웨어 및 금속충격파 검출 및 판별 알고리즘을 개발하여 영광 1,2호기에서 기존 설비와 병렬운전중이다.

2017년 봄 한국과 프랑스는 우연하게도 새로운 정부가 탄생하였고, 각각의 새로운 정부는 여성들에게 우호적인 듯한 모습을 띠고 나타났다. 프랑스의 마크롱 정부는 내각에서부터 남녀비율을 5:5로 맞추어 획기적인 면모를 보여주었고, 문재인 정부는 마크롱정부와는 비교할 수는 없으니 여성에게 우호적인 모습으로 비추어졌다. 본 연구는 여성우호적인 모습으로 비춰진 두 정권의 실상이 어떠한가를 분석하면서 두 정권에서의 여성정치세력화의 본 모습을 찾아내는데 그 목적이 있다.

In this paper, the sequentially rotated array(SRA) antenna with 256 elements applicable for satellite broadcasting reception was designed by arraying this triple(4+8+4 element) SRA antenna as a sub-array antenna. The structure of a triple SRA antenna is a combination of three coaxial shells composed with 4 elements of inner shell and 8 elements of middle shell and 4 elements of outer shell. In accordance with the optimum design rules for realizing a high gain antenna, the sequential array factors(M, P) of inner shell and outer shell have been chosen M=4 and P=1 and that of middle shell has been chosen M=8 and P=1. The results of the simulation and the measurement for the proposed triple(4+8+4 element) SRA antenna and the SRA antenna with 256 elements show good characteristics on the integration, bandwidth of the axial ratio and the cross-polarization, the gain respectively.

We have studied the chemisorption of oxygen at room temperature on Fe layers deposited on Pt(111) substrates by using core-level X-ray photoelectron spectroscopy. It was found that the oxygen atoms are chemisorbed when the thickness of the Fe layers is not larger than 6 monolayers. Upon post-annealing, it was found that part of the chemisorbed atoms are desorbed at a temperature range 600 - 700 K, after which the intermixing between Fe and Pt atoms occurs. The overall trend of this intermixing was very similar to the Fe/Pt(111) surface without oxygen exposure. The remaining oxygen adatoms, the amount of which is about a half of the total, were found to be eventually desorbed from the surface upon post-annealing at 1000 K. The binding energy of this phase was higher than that of the oxygen atoms desorbed at lower temperatures by 1.3 eV.

We have many problems in the teaching and learning of proof, especially in the demonstrative geometry of middle school mathematics introducing the proof for the first time. Above all, it is the serious problem that many students do not understand the meaning of proof. In this paper we intend to show that teaching the meaning of proof in terms of historic-genetic approach will be a method to improve the way of teaching proof. We investigate the development of proof which goes through three stages such as experimental, intuitional, and scientific stage as well as the development of geometry up to the completion of Euclid's Elements as Bran-ford set out, and analyze the teaching process for the purpose of looking for the way of improving the way of teaching proof through the historic-genetic approach. We conducted lessons about the angle-sum property of triangle in accordance with these three stages to the students of seventh grade. We show that the students will understand the meaning of proof meaningfully and properly through the historic-genetic approach.
