An experimental study on drilling of stainless steel is conducted using TiAlN coated drills and HSS twist drills with several cutting conditions; feed rate, spindle rotational speed, and dry/wet cutting. The effects of number of hole on the thrust force are examined by cutting force measurement. The flank wear of the drills and the change of hole diameter are quantitatively observed using a vision system. It is found that the thrust force in drilling with TiAlN coated drills decrease under dry and wet machining, whereas the flank wear resistance is improved.

Arare case of primary malignant melanoma of central nervous system in 12-month-old infant with neuro-cutaneous melanosis is presented. Primary malignant melanomas in central nervous system are very rare in children, however, it is known that leptomeningeal melanosis is malignant in 40-50% with neurocutaneous melanosis. Spinal MRI, brain CT and MRI showed diffuse intradural extramedullary mass of entire spinal cord and enhancing mass in brain stem. CSF cytology revealed abnormal cells. Biopsy from leptomeninges of posterior fossa was compatible with malignant melanoma.

宇治十帖の方途-薫の道心と恋の構造

김태영 ( Tae-young¸ Kim ) 한림대학교 일본학연구소 2020 翰林日本學 Vol.0 No.37

本稿では、第三部の物語のはじめの部分といえる「匂宮三帖」における薫の道心と恋のあり方について考察した。第三部の最初の巻「匂兵部卿」には、薫が初めて登場し、彼の道心の由来が述べられている。「匂兵部卿」巻の表現構造では、光源氏と薫を比較対照しつつ、薫のみではなくその道心をも相対化している語りの構造が見られる。薫の道心は彼の幼い時に聞いた自らの出生に関する疑惑に根ざしている。薫は自分の実父が柏木であることを知っているが、以後の物語において、柏木の罪が薫の内面において深く問い直されることはなく、薫の出生の秘密が外化する方向にも物語は展開しない。薫における柏木の「罪」の行方は、第三部の三番目の巻「竹河」と「匂兵部卿」巻との比較を通じて明らかになる。竹河巻は、匂兵部卿巻に語られていたことを「ひが事」と否定することにより、薫の出生の秘事を表面上払拭し、薫の恋における姿を語り出すことができたと考えられる。また、竹河巻では、表面上は薫の秘事について語らない形式を取りつつも、語りや表現のレベルにおいて薫における柏木の「影」を暗示していく〈物語の方法〉が用いられており、こうした〈語りの方法〉は「宇治十帖」において一貫して見られている。竹河巻は、まさしく「宇治十帖」の序として、主人公薫の生のあり方、薫をめぐる語りの方法を象徴的に示している巻であると思われる。 In 「Niobyeongbukyeong」 which is the first volume of 『Genji Monogatari』 composed of three parts, the main character, Kaoru appears for the first time, and the origin of his Buddhist doctrines is described. In the analysis on the representation structure of the relevant volume, it takes the structure of katari that relativizes not only Kaoru, but also his Buddhist doctrines by comparing and contrasting Hikaru Genji and Kaoru. Kaoru’s Buddhist doctrines is rooted in his doubt about his own birth that was told in his childhood. Even though Kaoru knows that his real father is Kashiwagi, the following monogatari does not describe the scenes in which Kaoru agonizes over Kashiwagi’s sin, and does not even reveal the secret of Kaoru’s birth. The monogatari in the third part does not show the method to explore the meanings of < sin > in the character’s inner side just as the second part. The third volume 「Takegawa」 of the third part is very remarkable in the aspect of issues like gatari and character set-up. The volume 「Takegawa」 denies what has been told in the volume 「Niobyeongbugyeong」 as a 「wrong story」, which is to superficially dispel the secret of Kaoru’s birth, and also to start talking about Kaoru’s look of love.

김태영,노윤찬,김홍수,강윤석,남기대 ( Tae Young Kim,Yun Chan Rho,Hong Su Kim,Yun Seog Kang,Ki Dae Nam ) 한국공업화학회 1996 공업화학 Vol.7 No.2

N-아실 아미노산계 음이온성계면활성제 중 sodium N-acyl-N-methyl-β-alaninate, sodium N-acyl sarcosinate 그리고 sodium N-acyl-N-methyl taurate 유도체 12종을 선택하여 묽은 수용액내에서 임계미셀농도와 미셀화 영역을 결정하는 새로운 방법으로서 컴퓨터프로그래밍에 의한 표면장력 곡선의 최대화를 제안하였다. 임계미셀농도와 미셀화 영역은 몇몇 실험치를 직접 프로그램에 대입함으로써 곡선의 최대화에 의해서 이론적으로 산정할 수 있다. 이론적으로 구한 임계미셀농도값들은 실측치와 거의 일치함을 알 수 있다. Micellization range and cmc for the dilute aqueous solution of N-acyl amino acid type anionic surfactants, that is, sodium N-acyl-N-methyl-β-alaninate, sodium N-acyl sarcosinate and sodium N-acyl-N-methyl taurate were investigated by computer programming. The extreme of the curvature of σ(C) as a new suggested method to determine the cmc and the micellization range was accomplished with computer programming. The values of cmc and micellization range can be obtained by the extreme of the curve by direct processing of only a few experimental data. The values of cmc particulary was in good agreement with those deduced intuitively from the shape of experimental curves of σ(C).

In the proposed paper, we designed low phase noise frequency synthesizer for Ku-band. The proposed up-mixing frequency synthesizer consists of narrow local oscillation part and variable frequency oscillation part. To improve the phase noise of frequency synthesizer, we analyze how the configuration of frequency synthesizer affect the phase noise. The implemented frequency synthesizer reduce the phase noise. The phase noise is -95.18dBc/Hz at 7kHz frequency offset in 16GHz and -94.27dBc/Hz at 7kHz frequency offset in 16.125GHz.

이득 분산이 다중 영역 복소 결합 DFB 레이저의 Self-Pulsation 특성에 미치는 효과

김태영,김부균,Kim, Tae-Young,Kim, Boo-Gyoun 한국광학회 2007 한국광학회지 Vol.18 No.1

이득 분산이 두 개의 복소 결합 DFB 영역과 위상조정 영역으로 구성되는 다중 영역 복소 결합 DFB 레이저에서 발진하는 두 모드의 비팅에 의한 self-pulsation (SP) 주파수와 출력 파워의 변조지수에 미치는 영향에 대하여 살펴보았다. 능동 영역의 이득이 최대가 되는 파장을 두 DFB 영역의 발진 모드의 파장 중심 또는 브래그 파장 중심에 위치시킨 경우가 특정 DFB 영역의 발진 모드의 파장 또는 브래그 파장에 위치시킨 경우에 비하여 두 DFB 영역의 브래그 파장 차이, ${\Dalta}{\lambda}_{B}$, 증가에 따른 두 발진 모드가 받는 이득 차이가 적게 발생하여 최대 SP 주파수가 크고, 변조지수 특성도 좋음을 볼 수 있었다. 또한 능동 영역의 이득이 최대가 되는 파장을 두 DFB 영역의 브래그 파장 중심에 위치시키는 경우가 발진 모드의 파장 중심에 위치시키는 경우에 비하여 더 큰 최대 SP 주파수를 얻을 수 있었고 변조지수 특성도 더 우수함을 볼 수 있었다. The effect of gain dispersion on the self-pulsation (SP) characteristics due to the mode beating of two modes emitted in a multisection DFB laser composed of two complex-coupled DFB sections and a phase control section is investigated. When the peak wavelength, ${\lambda}_{p}$, of the gain spectrum of the DFB section is positioned in the center of the lasing wavelengths or the Bragg wavelengths of the two DFB sections, the maximum SP frequencies are higher and the modulation index has better characteristics compared to those cases for ${\lambda}_{p}$ fixed at the lasing wavelength or Bragg wavelength of one DFB section, when the difference between the Bragg wavelengths of the two DFB sections, ${\Dalta}{\lambda}_{B}$, is varied. When ${\lambda}_{p}$ is positioned in the renter of the Bragg wavelengths of the two DFB sections, the maximum SP frequency is higher and of the modulation index has better characteristics compared to those of the case for ${\lambda}_{p}$ positioned in the center of the lasing wavelengths of the two DFB sections.

Emergency free flap has been advocated to cover the severely injured extremity for more than two decades, due to its numerous advantages such as low incidence of flap failure and infection rate and early recovery of function. But there are very few reports about these. The authors report their experience in using the emergency free flap for reconstruction of extremities. For last 10 years, 4 patients ranging from 3 to 27 years old with severely traumatized extremities were treated with emergency free flap transfers. Three were males and the other was a female. Flap size ranged from $2{\times}5\;cm^2$ to $7{\times}22\;cm^2$. The locations of the recipient site were the dorsum of the foot, the cubital fossa, the popliteal fossa and the upper arm. The number of the donor sites used was as follows: one scapular flap, two parascapular flaps, and one radial forearm flap with the radial bone. All of the flaps survived without need of re-exploration. There was no infection or flap loss. Involved joints have recovered a normal range of motion. Therefore, we consider that the emergency free flap is a very safe and reliable method to cover the severely injured extremities.
