1996년 이후부터 전산화단층촬영 검사가 건강보험급여대상이 되면서 이용률과 보급률이 더욱 증가되고 있으며 검사범위의 확대, 검사시간의 단축, 반복검사의 용이성, 이용의 편리성, 결과의 신뢰성, 장치의 구조적인 요소 및 검사 시행 횟수의 증가 등으로 검사량이 증가되고 있는 실정이다. CT 검사 건수의 증가요인으로 새로운 CT장비의 개발과 더불어 급격한 장비도입 증가 추세가 있으므로 이에 본 연구에서는 의료기관 종별 및 시기별 CT 장치 보유현황과 검사료간의 관계를 파악하였다. CT 장비는 병원급은 증가하고 있는 추세이나 의원급은 감소하고 있는 것으로 나타났다. CT진료비 청구는 80%이상이 종합전문요양기관과 종합병원에서 청구하는 것으로 나타났다. 이에 본 연구에서는 고가의료영상 진단 장비인 CT의 세대별 발달장비 도입 시기에 따른 우리나라 CT의 현황을 조사 분석하여 제시하여 고가의료장비 수급의 정책수립의 계기 및 기여하고자 한다.

Purpose: This study aimed to compare and assess changes of visual functions in viewing an anaglyph 3D image. Methods: Visual functions were examined before and after viewing a 2D image and an anaglyph 3D image with red-green glasses on seventy college students (mean age = 22.29${\pm}$2.19 years). Visual function tests were carried out for von Graefe phoria test, accommodative amplitude test by (-) lens addition, negative relative accommodation (NRA) and positive relative accommodation (PRA) test, negative relative convergence (NRC) and positive relative convergence (PRC) test, accommodative facility, and vergence facility test. Results: Assessment of the visual functions indicated that near exophoria and accommodative amplitude were reduced after viewing a 3D image, and although there were small changes in relation to these findings, NRC and PRC showed tendencies to increase and decrease at near, respectively. There were no significant changes with NRA and PRA, and accommodative and vergence facility were shown to have improved. Conclusions: Changes of visual functions were more in the 3D image than the 2D image, especially at near than distance. Particularly, the improvement of accommodative and vergence facility could be related to an effect of subsequent accommodation and vergence shift to have stereopsis in the 3D image. These results indicate that an anaglyph 3D image may, to some extent, be the effect of vision training such as anaglyphs.

To Analysis of Correlation of Visual Function Findings, by assessing convergence and accommodation, 92 selected objects without any ocular diseases by apperatuses of visual chart(Shinnippon CT30) and phoropter(Shinnippon VT10) at a shan distance(40 cm) were tested upon MEM retinoscopy(Welch Allyn, USA), BELL retinoscopy(Welch Allyn, USA), binocular accommodative facility (${\pm}2.00$ D nipper, Bernell Co., USA), vergence facility(prism nipper, Bernell Co., USA). The results showed as follows. MEM retinoscopy(accommodative lag) showed the same result of a right eye and left eye. Bell retinoscopy(accommodative lag) showed higher correlations between right and left eye than MEM. The lower accommodative lag meant the higher accommodative facility. The binocular accommodative facility(polaroid) was higher than binocular accommodative facility(red-green). Correlations of accommodative facility between right and left eye were higher, and as the higher monocular accommodative facility also meant the higher binocular accommodative facility, monocular and binocular accommodative facilities were relative to vergence facility, These findings can be used as a clinical guide by curing patients' visual function.

Purpose: The purpose of this study was to investigated the effect of vision training methods on the visual function and sensation symptoms of patients with convergence insufficiency. Mehtods: The vision training observation group included 35 clients who had binocular vision disorders without opthalmic diseases or vertical phoria. They took the each vision training once a week for eight weeks and were investigated for the function and sensation symptoms changes of binocular vision. Results: According to the results, all vision training methods showed improvement of binocular vision function and sensation symptoms. For Worth 4 Dot test, Titmus test and red lenses observed the changes in fusion rate, all the training methods showed similar improvements. Conclusions: The study proved that vision training methods for patients with binocular vision was effective for the improvement of the phoria, function and sensation symptoms of these patients.

I performed the refraction and binocular test for study of binocular abnormalities. The problems of the accommodation and binocular on subjects was need to the correction of the refractive error. also the subjects was need to a specific treatment for each of the problems. On two patients who had convergence excess, The full corrections of eyeglasses or (+)ADD for near vision were prescribed and the subjects trained for 4 weeks. After 4 weeks, the unconvenience of near vision have more decrease, and the objective test have good results. On clinical, If the optical correction and vision therapy was applied the treatment for binocular abnormalities. The continuous research of vision training in binocular abnormalities will be good results for treatment of several binocular abnormalities in the future.

Purpose: The purpose of this study was to investigate the effect of vision training using MYSTERY CIRCLE system on patients with exophoria and intermittent extropia. Mehtods: The vision training observation group consists of 26 clients who had exophoria (n=18) and intermittent extropia (n=8) without opthalmic diseases or vertical phoria. Our clients took each vision training once a week for eight weeks and were investigated for the symptoms changes of binocular vision. Results: According to the results, MISTERY CIRCLE vision training methods improved the binocular vision function and sensation symptoms. For Worth 4 Dot test, Titmus test and red lenses showed fusion rate changes. Conclusions: The study proved that MISTERY CIRCLE vision training system for patients with binocular vision was effective for the improvement of the binocular vision symptoms of these patients.

Purpose: This study aimed to analyze the epidemic period of RSV infection and evaluate the appropriate time of palivizumab immunoprophylaxis. Methods: From January 1991 to July 2012, nasopharyngeal (NP) aspirates were obtained from patients who visited Seoul National University Children's Hospital for respiratory symptoms. NP samples were used to detect respiratory viruses. Among them, we analyzed the positive number and detection rate of RSV infection in two-week interval. The beginning of RSV season was defined when RSV positive number was more than 4 and RSV detection rate was over 10%. From January 2007 to March 2014, we analyzed the starting time of palivizumab immunoprophylaxis for the infants at high risk. Results: The RSV detection rate was 2,013/21,698 (9.69%) over 22 years. The median RSV season was from $2^{nd}-3^{rd}$ week of October to $1^{st}-2^{nd}$ week of February. The earliest starting week was the 3rd week of July in year 2001, and the latest end week was the 3rd week of May in year 1990. Palivizumab immunoprophylaxis was initiated most frequently at the 3rd week of October (18.7%). However, the percentage of starting palivizumab on the 1st week of September has increased from 3.8% in the year 2007 to 14.1% in 2013. Conclusions: The year to year variability of RSV season exists. The starting time of palivizumab immunoprophylaxis should be adjusted based on the season of RSV epidemic.

우리는 흔히 ‘살아있음’에 대한 가치를 망각한 채 그날그날을 보내버리고, 어느날 갑자기 우리 앞에 닥친 ‘건강에 대한 위협’이라는 놈 때문에 당황하며 또 더러는 좌절하게 된다. 심한 경우, 우리의 의지 따위(?)와는 관계없이 생명은 “죽음” 앞에 무릎을 꿇고 만다. 불가항력의 경우도 있기는 하지만 대개는 시기를 놓쳐버리는 때가 허다하므로 뒤늦게 후회해 보았댔자 무슨 소용이 있으랴. 어린이 심장병 집단검사만 해도 그렇다. 필요한 일이라는 것은 알지만 실천으로 옮겨지는 예는 드물다. 여기 선천성 심장병의 일종인 “동맥관개존증”이라는 병을 앓고있다가 학교에서 실시한 심전도 집단검사에서 조기발견하여 시기적절하게 치료를 끝내었고, 이제는 건강한 모습으로 미래를 향해 달음박질하는 한소녀를 소개한다. 혹시라도 건강에 관심을 두지 않았던 사람이 있다면 그 귀감이 될 수 있기를 바란다.
