Optimum field size for the whole body stereotactic radiosurgery was studied. Dose distributions from the various sizes of targets (diameter 1cm to 7cm, icm interval) were used for this study. Planing scores, expressed as the Target Coverage Index (TCI), were calculated for various target Margin ranged 0cm to 0.5cm. Highest scores were obtained for no Margin to the target size. The target Margin -0.5cm to 0cm to the target showed best TCI the cases of the target size larger than 6cm diameter. No Margin or 0.5cm Margin generated best TCI for less than 2cm cases. Prescription to 80~90% gives best results.

X-선 혹은 감마선 등 종래의 방서선 치료는 양성자 혹은 이온에 의한 치료방법의 등장함에 따라 퇴조할 것으로 보인다. 그 이유는, 양성자 등 전하를 띄는 입자치료기술이 치료 후 후유증이나 암의 재발을 현저히 억제시킬 수 있기 때문이다. 전하를 띄는 입자는 암 조직 전후의 정상 조직에 최소한의 피폭을 주나, X-선이나 감마선과 같은 광자들은 암 조직 전후의 정상세포가 암세포로 변화될 수 있는 정도의 피폭량을 주는 것으로 알려져 있다. 현재 임상 중인 양성자(혹은 극히 일부의 탄소이온 치료기)치료기는 1990년 미국의 로마린다(Loma Linda) 대학에서 최초로 건립된 방식인 사이클로트론 혹은 싱클로트론 가속기와 빔라인 및 겐트리(gantry)로 구성된다. 그 장치의 거대함만큼이나 가격과 유지비 등에서 일반 소형병원에서 운영하기에는 쉽지 않아 보인다. 이에 본고에서는 소형병원에서도 운영할 수 있는 저비용의 레이저 양성자(이온) 가속방식의 등장 배경과 향후 전망을 논하고자 한다.

Purpose: The purpose of this study was to investigate the effect of olfactory stimulation on the balance ability of the elderly. Design: Randomized controlled trial. Methods: A total of 20 subjects were randomly assigned to the olfactory stimulation group (2 males and 8 females) and deception olfactory stimulation group (3 males and 7 females). Subjects were subjected to 30 second 3 times olfactory stimulation and deception olfactory stimulation, and the assessment measured pre and post postural distance and postural speed. Results: In the elderly, the olfactory stimulation group was significantly improved the postural distance and postural speed in the eyes closed state than the deception stimulation group (p<.05). Conclusion: As the information is provided through the olfactory stimulation, the postural distance and postural speed are significantly improved. therefore, it is expected that the olfactory stimulation in the elderly will be an effective intervention method to prevent fall.

We developed a Microcurrent acupuncture point treatment equipment using micro-controller AVR. This equipment can generate a sine wave, triangle wave, square wave and DC. The frequency range of waves like the sine wave and the triangle wave is 1 - 320 Hz and the output range of DC is $40-200\;{\mu}A$. The duration is controllable between a minute to 30 minutes.

This study was conducted to evaluate the effect of phased horticultural therapy(HT) program on the experience of psychologic therapy and the development of job and social integration in the mentally handicapped persons. In this study, the mentally handicapped persons participated in HT program were chosen in disabled person's welfare institute of Jeonnam. HT program was performed twice a week with 1 hour activity for 4 months. As a results, the mentally handicapped persons participated in HT program showed high interest of horticulture and improvement of self-respect and the high satisfactory degree of HT program. Therefore, the mentally handicapped persons were showed the experience of both physical and mental therapy, improvement of self-esteem scale and sociality in HT program. Also, the application of HT program with continuously interest will be showed high improvement of physical, psychological and sentimental. In the course of this HT program progress, horticultural therapist and social welfare officer were showed the limitation of role. Therefore the leaders of group for successful HT program be required the comprehensive plan of more efficient HT program and induced technique of continuously up-phased improvements in HT program progress.

Acquired bronchoesophageal fistula rare. Conservative treatment such as endoscopy is widely used. The recurrence rate after endoscopic treatment, however, is not well known. We report here on a case of a 54-year-old female who presented with recurrent bronchoesophageal fistula after endoscopic treatment that filled the fistula tract with $Histoacryl^{(R)}$.

Risperidone은 D$_2$-수용체와 HT$_2$-수용체 차단효과를 동시에 지녀, 차세대 항정신분열증 치료제로의 가능성을 보이고 있는 약물이다. 그러나 risperidone의 주대사가 CYPIID1에 의할 가능성이 시사되고 있다. 본 연구에서는 향후 항정신병 치료제의 임상 제 1상 연구의 적정 모형 검토를 위해 risperidone율 모델 약물로 체내 약물의 동태, 내약성 및 약물 유전학적 특성등을 검토하였다. CYPIID1의 대사능을 검정한 12명의 정상 성인(11명: extensive metabolizer, 1명: poor metabolizer)을 대상으로 risperidone 투여 시험(placebo, 1, 2 mg)을 무작위 단일맹검 교차시험으로 시행하였다. 투약후 72시간까지 경시적으로 혈액, 뇨 채취 및 ECG lead II, 혈압/맥박의 변동 등을 측정하고, visual analog scale에 의해 중추신경계 주관적 증상들을 관찰 하였다. 혈장 risperidone 및 그 활성형대사물 9-OH risperidone 및 prolactin 농도는 radioimmunoassay법으로 측정하였다.
