여러 가지 방법으로 교정한 Binder 증후군: 비상악골의 사진계측학적분석
한기환,차명규,함희정 대한성형외과학회 2003 Archives of Plastic Surgery Vol.30 No.4
Binder's syndrome has some characteristic signs, such as orbital hypotelorism, shortened and flat noses, diminutive columella, crescent shaped nostrils, acute nasolabial angle, convex upper lip, class III malocclusion, absent anterior nasal spine, and maxillary hypoplasia. Binder's syndrome patients usually need the correction of the following three: the hypoplatic nose, the perialar flatness due to underdevelopment of the piriform margin, and the hypoplastic maxilla with its malocclusion. The authors treated eleven(n=14) patients through various surgical techniques depending on the clinical signs. In order to correct the nasomaxillary hypoplasia, the autogenous bones, the autogenous cartilages and the alloplastic implants were used. In three patients with severe nasomaxillary retrusion, the combined Le Fort I and II osteotomies and the perinasal osteotomy were performed. The results were analyzed using the proportion indices from the preoperative and postoperative lateral photographs of the patients. The postoperative values of all the proportion indices were significantly higher compared to the preoperative ones. For nasal dorsal augmentation, columellar lengthening and peripiriform augmentation, autogenous bone grafts were found to be very effective. The use of high-density porous polyethylene sheets for columellar lengthening was preferred over the use of nasal septal cartilages. Two types of osteotomy were the most effective for nasomaxillary augmentation in severe deformity.

A total of 21 patients were operated. Via a columellar labial incision, the upper lateral cartilages were separated from the septum. A submucous resection of the septal cartilage was carried out. After rasping the convex lateral nasal wall of the unaffected side, a low- to-low lateral nasal osteotomy was conducted. Along the deviated dorsal line at the bony vault passing the submucous tunnel, a paramedian nasal osteotomy was performed. The convex side of the nasal bone flap was contoured by rasping. The convex side of the “T”- shaped dorsal septum was trimmed. A total direct septal extension graft of the septal cartilage was done and the alar cartilages were suspended to it. The postoperative results were evaluated by photogrammetric analysis processed by a “neon glow” filter in Adobe Photoshop. The distance from the nasal midline to the most deflective point at 5 levels was measured, and the proportion indices were obtained in regard to intercanthal distance. The results revealed improvement in all levels (p < 0.05), although not perfect. In summary, this technique can result in a clinically good-looking in spite of a slight deflection that still exists.

The Iceman Cometh에 나타난 Pipe Dream
한기환 한국영어영문학회 경남지부 1987 현대영미어문학 Vol.4 No.-
In The Iceman Cometh(1946) there is neither poignant yearning nor feverish quest. In this painless purgatory, not love and peace, but peace alone is the central human need. So it is being satisfied for most of the derelicts from the opening curtain. The action of this play takes place in the back room and a section of the bar of Harry Hope's saloon. Here fifteen derelicts keep themselves alive on alcohol and the pipe dream that they have been or some day will be respectable. At least unconsciously, they know the truth about themselves and each other, but they know, too, the vital necessity of illusion. The pipe dreams of the characters in The Iceman Cometh have the same function: they make life tolerable while the dreamers wait for Hickey or Death. As much as each of the derelicts permits himself to understand anything, he knows that the pipe dreams, his own included, are a game, that they are not real. Each man mocks the dreams of the others as insubstantial and illusory, but the mockery is a defensive irony. Hickey's pipe dream is that he loved his wife, Evelyn. Parritt's are that he betrayed his mother for patriotic reasons and that he did it for money. Larry's are that he no longer cares about life and that he waits for death. Thus, through the play we can see that 0'Neill proposed three ways in which men can find peace. One of these is the pipe dream. Deprived of this, men begin to die.

정신지체아 두발 중 중금속 함량 III - 수은과의 관련성 -
한기환,장봉기,박순우,김두희,Han, Ki-Hwan,Jang, Bong-Ki,Park, Soon-Woo,Kim, Doo-Hie 대한예방의학회 1989 Journal of Preventive Medicine and Public Health Vol.22 No.3
정신지체와 인체내 수은 함량과의 관련성을 보기 위해 정신지체아 297명(가정이 있는 아동이 다니는 특수학교 1개교의 132명과 고아로 구성된 특수학교의 165명)을 대상으로, 학업성적이 중위권 이상인 일반 국민학교 학생 117명을 대조군으로 하여 두발 중 수은 함량을 원자흡광광도계를 사용하여 측정, 비교해 보았다. 발 중 수은 함량의 연령에 따른 차이는 없었다. 정신지체아에서 대조군에 비해 두발 중 수은량이 유의하게 높았다(남자 지체아 : 3.02ppm, 남자대조군 : 2.20ppm, 여자 지체아 : 2.76ppm, 여자 대조군 : 2.02ppm). 가정이 없는 정신지체아의 경우 수은 함량이 날자가 3.27ppm, 여자가 3.04ppm으로써 대조군의 남자 2.20ppm, 여자가 2.02ppm에 비해 각각 통계학적으로 유의한 차이가 있었으며, 가정이 있는 정신지체아군은 남자가 2.76ppm, 여자가 2.31ppm으로써 남자는 대조군과 유의한 차이가 있었으나 여자는 대조군에 비해 수치는 다소 높았으나 통계학적 유의성은 없었다. 그리고 가정이 없는 정신지체아가 가정이 있는 경우에 비해 유의한 차이가 있었다. 그러나 정신지체 정도와 두발 중 수은 함량과는 유의한 차이가 없었다. 동반 질환은 Down씨 증후군, 전간, 뇌성마비, 자폐증 등이 있었으며, 남자의 경우에서는 Down씨 증후군과 뇌성마비를 동반한 경우, 여자에서는 Down씨 증후군과 자폐증을 동반한 경우에 대조군에 비해 통계학적으로 유의하게 높았다. 그리고 동반된 질환이 없는 경우가 대부분이나 이들고 대조군에 비해 유의하게 높았다. 동반된 장애유형은 언어장애가 40.4%로 가장 많았고 지체부자유, 정서장애의 순이며 중복장애자는 두발중 6ppm이 초과되는 6명중 66.7%, 3-6ppm군에서는 10.4%, 3ppm이하군에서는 15.7% 이었다. 본 연구의 결과로 볼 때 정신지체아군에서 수은에 노출될 기회가 더욱 많았을 것이며 이것이 정신지체의 한 인자로 작용했을 가능성을 배제할 수는 없을 것으로 추측된다. 이에 따라 이들의 생활공간에 대한 환경조사, 식생활 및 식습관 조사 등을 통해 정신지체와 수은과의 인과관계를 밝혀 나가야 할 것으로 생각된다. The relationship between mercury level of hair and mental retardation was investigated. The 297 subjects with mental retardation were drawn from two schools providing special educational services, one, consisted of children living in an orphan home, another, children with parents. The 117 centre] subjects were drawn from whom had got average or above average academic achivement in a regular elementary school. Hair sample were taken from the nape of the neck and the mercury analysis was carried out on an atomic absorption spectrophotometer(IL 551). There was no relationship between mercury contents and age, and there was a statistically significant difference in mercury contents between male and female in the mentally retarded children living with parents. Children in the retarded group had significantly higher mercury contents compared with control group except the female group with parents. Also, the mercury levels in the retarded group living in an orphan home were significantly higher than that of the retarded group with parents. The concomitant diseases were Down's syndrome, epilepsy, cerebral palsy and autism. There were statistically significant differences in hair mercury levels in the cases of accompanying Down's syndrome and cerebral palsy in male and Down's syndrome and autism in female compared with the control group of the same sex. The most accompanying handicap was speech disturbance(40.7%) and the others were crippled, emotional disturbance etc. The percentages of double handicap were 66.7% among 6 persons exceeding 6ppm of their hair mercury contents. 10.4% among $3{\sim}6$ ppm and 15.7% among the group of 3ppm or less. The findings of this study suggest that the more opportunities of exposure to mercury in mentally retarded children may have occurred, so it can not be excluded the possibility of mercury as a contributing factor to mental retardation. Therefore, the causal relationship between mercury levels and mental retardation should be established through the examinations about their living environments, dietary pattern, eating habit etc.
