New Fixation Method Using Two Crossing Screws and Locking Plate for Cubitus Varus Deformity in Young Adult Elbow

Byoung Jin Kim,Jong Hwan Seol,Myung Sun Kim 대한견주관절의학회 2016 대한견주관절학회지 Vol.19 No.1

Many types of osteotomy have been proposed for the treatment of cubitus varus deformity of the elbow, and various methods for fixation of the osteotomy site have also been described. However, no method has been perfect. We treated two cases of cubitus varus elbow deformity with step-cut osteotomy using a new fixation method with two crossing screws and an anatomically designed locking plate. Active assisted elbow range of motion (ROM) exercise was permitted at postoperative 3 days, after removal of the drainage. Preoperative and postoperative humerus-elbow-wrist angles and ranges of motion of the two patients were compared. At 3 months followup, each patient had recovered the preoperative elbow ROM, and achieved the complete bony union of the osteotomy site and proper correction of the cubitus varus deformity. In addition, the appropriate remodeling of the lateral bony protrusion was observed. Therefore, we introduce a new fixation method for achievement of stable fixation allowing immediate postoperative elbow motion after corrective osteotomy for cubitus varus deformity in young adults.

The Role of Lunate Morphology on Scapholunate Instability and Fracture Location in Patients Treated for Scaphoid Nonunion

Byoung-Jin Kim,David Kovacevic,Young-Min Lee,Young-Min Lee,Jong-Hwan Seol,김명선 대한정형외과학회 2016 Clinics in Orthopedic Surgery Vol.8 No.2

Background: To determine the association between lunate morphology and the scapholunate instability using radiographic images, and investigate the association between lunate morphology and scaphoid fracture location. Methods: Between January 2003 and December 2011, we retrospectively evaluated the plain radiographs and computed tomography (CT) images of 70 patients who underwent surgical intervention for a scaphoid nonunion, in order to determine the association between lunate type (I or II) and scapholunate instability or scaphoid fracture location. We determined the scaphoid fracture location using the fragment ratio and measured the radiolunate angle and capitate-triquetrum (C-T) distance. Results: A type II lunate was present in 68.6% (48 of 70 cases). Mean fragment ratio of fracture location was 50.6% in the type II lunate group and 56.2% in the type I lunate group (p = 0.032). Sixteen of the 70 patients had dorsal intercalated segmental instability (DISI) deformities. Nine of 22 cases showed DISI deformity in type I lunate and 7 of 48 cases showed DISI deformity in type II lunate (p = 0.029). However, there were no significant differences between the presence of DISI deformity and fracture location (p = 0.15). Morphologic comparisons by both plain radiography and CT indicated a mean C-T distance in the type I lunate group (22 cases) of 2.3 mm and 5.0 mm in the type II lunate group (48 cases). The C-T distances were significantly correlated with lunate morphology (p = 0.001). Conclusions: A type II lunate was associated with low incidence of DISI deformity and proximal location of fracture in patients presenting with a scaphoid nonunion.

기업과 제품과의 다양한 경쟁으로 기업은 다원화된 국제적인 경쟁 시대를 맞이하고 있으며, 충성도라는 의미에서, 신뢰도라는 의미에서, 만족도라는 의미에서 사용 되듯이 한 기업의 이미지는 소비자의 제품을 선택하는 중요한 이유가 되기도 한다. 이미지는 기업에 있어 현실적인 힘이 되어주며 미래의 성장과 발전을 좌우하는 중요한 기준이 되는 것이다. 기업 브랜드 이미지는 특정 기업에 대해 이해관계를 맺고 있는 다양한 관계자 집단이 마음속에 그리고 있는 심상을 의미한다. 이처럼 기업 브랜드 이미지는 기업문화가 가시적으로 표출되어 나타나는 일련의 동질성을 띄는 인식체계이므로 제품 디자인 이미지와 기업 브랜드 이미지는 불가분의 관계에 있다고 할 수 있다. 디자인 경영 및 역량을 강화한다는 것은 결코 쉬운 일이 아니지만, 시급히 역량 강화에 초점을 두어야할 시기인 것은 이제 현실적인 차원을 넘어선 상황으로 제시되고 있다. 본 연구는 소비자가 제품을 구매, 사용함으로서 자연스럽게 인식 되어지는 기업 브랜드 이미지와 그 기업에서 생산 판매되어지는 제품의 디자인 이미지와의 연계관계와 상관관계를 다차원적 척도법을 이용하는데 있어 정합성을 연구하고자 한다. 실제 이미지를 이용하여 소비자, 사용자의 잠재된 이미지를 도출함에 있어 어떠한 기준으로 관찰하고 분류하고 체계적으로 분석하였는지에 관한 실험을 실시한다. 따라서 소비자. 사용자의 잠재니즈를 이해하는데 아직 논리적으로 설명되지 않는 부분을 실체적인 방법론들을 적용하여 소비자의 기업 브랜드 이미지 인식과 기업에서 내세우는 제품 디자인 이미지의 정체성을 명확히 하고 객관적인 기준으로 변환할 수 있는 지표를 확립하기 위한 기초 연구를 하고자 한다.

Many researches have been studied on in-cylinder flow as one of dominant effects for an engine combustion. Specially because the combustion flame speed is mainly determined by the turbulence at the end of compression process. Tumble and Turbulence ahead of combustion is very important phenomenon. As this phenomenon make research certainly, combustion condition will effectively be improve. This paper describes analytical results of the tumble flow, intensity, turbulence inside the cylinder of maritime engine. 3-D computation has been performed by using STAR-CD v3.26 solver and es-ice.

1983年 1月에서 5月사이 大邱直轄市 北區 邑內洞 八溪扈에 마을 下水가 流入되는 河川水와 隣近의 簡易상수도 물에서 大腸菌 最適確數(MPN)을 觀察하였고, 分離된 大腸菌의 各種 抗菌劑에 對한 耐性樣相을 調査하였다. 河川水 100㎖ 當 大腸菌 最適確數는 95에서 2,400의 分布였다. 河川水의 大腸菌 總 404株가운데 219株(54.2%)가 抗菌劑 耐性菌이었다. 河川水의 耐性菌 分布의 藥劑別로는 Tc에 耐性인 菌流가 47.8%로 가장 높고, Su. Sm, Ap, Cb, Cm의 順이었다. Tp, Km, Cr, Ct는 32.4%가 耐性이었고 Na와 Gm에 耐性菌株는 없었다. ??點別로는 豚舍 由來菌여 Tc, Sm 및 Su의 藥劑에 耐性이 比較的 높고, 마을 下水가 流入되는 河川水에서 分離된 菌株가 多樣한 耐性樣相을 보였으며 最近 使用이 많은 Ap에 對한 耐性豚度가 顯著히 높아졌다. 多藥劑 重複耐性菌의 分難頻度는 豚舍由來菌에서는 耐性菌의 分離頻度는 가장 높은 반면, 多藥劑에 重複耐性의 傾向은 낮았다. 마을 下水 由來菌은 10劑에 重複耐性을 비롯하여 6劑以上 重複耐性인 菌株가 많아서 耐性의 重複度가 높았다. 畜舍 由來菌에 比해 사람 由來菌일 수록 多藥劑에 重複耐性의 頻度가 높은 것으로 생각된다. 특히 牛舍 廢水가 流入되는 河川水에서는 Tc에만 耐性인 菌株가 主로 많았다. 簡易水水道에서 導水된 上水 100㎖ 當 大腸菌이 1.8에서 220의 分布를 보였다. 이들 生活用水에서 分離된 大腸菌의 耐性樣相을 보면 總 52株 가운데 26株(50.0%)가 耐性이었고 耐性樣相도 6劑에 重複耐性인 것을 비롯하여 多藥劑에 耐性인 菌株가 많았다. R plasmid 保有菌株가 66株 (30.1%)였고 그중 1株는 生活用水에서 分離된 것이다. 藥劑別 R plasmid에 依한 傳達性耐性頻度는 Km에 가장높았고 그다음으로 Tp, Cm 및 Ap의 順 으로 높았다. 耐性傳達實驗결과 都合 119개의 R plasmid를 확보할 수 있었다. Water samples taken from five sites of stream where variom kinds of waste water were drained to and each two tap-water samples from three faucet were examined for the study of the most probable number (MPNj and antimicrobial drug resistance of E. coli during Jan. t o May, 1983. The range of MPN per 100 ml of sewage water was 95 to 2,400 and that of in tap-water. -isas 1.8 to 220. There was no significant difference of MPN in sxTvsge water by the sites and by the time of sampling. Two hundreds and ninteen strains(54.2% j of 404 E. coli strains isolated from sewage water u-ere resistant to one t o ten drugs tested. The frequency of resistant strains isolated from the sewage was highest to tetracycline(Tc) with 47.876 and followed by sulfisomidhe(Su), strep-tomycin(Sm), ampicillin(Ap), carbenicillin(Cb), and chlorampheniclo(Cm) in the decreasing order. The frequency of.resistant strains isolated from waste water of swine herd was higher than those of village sewage, but multiplicity of drugs resistant to was much higher than those of the swine. Most of the strains derived from swine herd were multiply resistant to three drugs of Tc, SIR, a3d su. The strains isolated from village sewage were more multiply resistant to drugs of comm on use in the treatment of the human infectious diseases. Twenty-six strains(50.0%) isolated from tap-water were resistant to drugs and resistance pattern was similar to those observed in sewage water. Sixty-six strains (30.175) of 219 resistant strains were carrying R plasmid. The frequexncy of transferable resistance by drugs was highest to kanamycin and followed by trimethcprim, Cm, and Ap in decreasing order. A total 119 of R plasmids were obtained.

센서 융합을 이용한 MAF 공정 특성 분석

김설빔(Seol Bim Kim),안병운(Byoung Woon Ahn),이성환(Seoung Hwan Lee) 대한기계학회 2009 大韓機械學會論文集A Vol.33 No.5

In configuring an automated polishing system, a monitoring scheme to estimate the surface roughness is necessary. In this study, a precision polishing process, magnetic abrasive finishing (MAF), along with an inprocess monitoring setup was investigated. A magnetic tooling is connected to a CNC machining to polish the surface of stavax(S136) die steel workpieces. During finishing experiments, both AE signals and force signals were sampled and analysed. The finishing results show that MAF has nano scale finishing capability (upto 8㎚ in surface roughenss) and the sensor signals have strong correlations with the parameters such as gap between the tool and workpiece , feed rate and abrasive size. In addition, the signals were utilized as the input parameters of artificial neural networks to predict generated surface roughness. Among the three netwoks constructed -AE rms input, force input, AE+force input- the ANN with sensor fusion (AE+force) produced most stable results. From above, it has been shown that the proposed sensor fusion scheme is appropriate for the monitoring and prediction of the nano scale precision finishing process
