There have been a lot of studies about Han-Ok, the Korean-style house, in the perspective of existing Han-Ok’s inheritance, but there are no practicality in supply of Han-Ok. The cause is considered the complexity of Han-Ok construction techniques and higher construction expenses comparatively by processing in the restricted range by the shortage of the manufacturing technology of materials. On the contrary, for evolution to the new Han-Ok that can be supplied to the present period, there are studies that is analyzed the connection between sub materials and for possible modeling by formulating of assembling way. Thus, this study try to suggest the CNC process for new Han-Ok construction to secure construction relate to construction technique, which is determined by few expert technicians that is pointed out as problems of Han-Ok.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Microvascular surgery has rapidly developed in the last 30 years and vessels of 1.0 mm can be anastomosed easily with a patency rate over 90 percent and is widely used in clinical practice with remarkable success. To obtain more successful microvascular anastomosis in smaller vessels, the improvement in methods of microanastomosis, the development of microvascular instruments including the operating microscope along with microsutures, and anticoagulants are needed. These improvements made microvascular anastomoses of vessels that are less than 0.5mm in extemal diameter possible. Huang et al.? performed anastomoses of the vessels in rats with an external diameter of 0.2 mm using a high magnification operating microscope, specially designed microinstruments, and fine sutures, and achieved a patency rate of 76 percent in the second postoperative week. However, we tried to anastomose vessels with an external diameter of 0.25 mm with ordinary instruments and 11-0 nylon. Animal studies on 180 rats were carried out by doing end-to-end anastomoses and 180 end-to-side anastomoses. In the end-to-end and end-to-side anastomoses, each 180 rats were then divided into 3 groups each. Group A was the control group. Aspirin and persantin were given orally in group B. Ticlopidine hydrochloride was given orally in group C. The method of end-to=end anastomosis was as follows : A superficial epigastric artery as small as 0.25 mm in diameter was severed transversely and longitudinal incisions, the length of the arterial diameter, were made down opposite sides of each end. Each flared fragment of the proximal end is approximated with each distal end and sutured together by only two stitches. The method of end-to-side anastomosis was as follows. In the side of the femoral artery an elliptical hole was made the same length of the circumference of the superficial epigastric artery, then the superficial epigastric artery was incised in the same manner as the end-to-end anastomosis. The flared ends of the superficial epigastric artery were then inserted into the hole of the femoral artery and sutured by four stitches. Light microscopic and scanning electron microscopic observation was performed serially at 3 days, 2 weeks, 3 weeks after the microvascular anastomosis for studying change of vessel diameter and histopathological changes at the microvascular anastomotic sites. The results were as follows : 1. The patency rate for the end-to-end anastomoses in the third postoperative week was 25% in the control group(A), 35% in the aspirin-persantin group(B), and 40% in the ticlopidine group(C) ; in the end-to-side anastomoses, 45% in group A, 50% in group B, and 60% in group C. 2. In the patency rate, the ticlopidine group is slightly higher than the aspirin-persantin group and even higher than the control group (P<0.05) in the end-to-end and end-to-side anastomoses. However, the end-to side group is higher in all 3 groups than the end-to-end one (P<0.1). 3. The intimal regeneration in all arteries was completed at end of the third postoperative week in the end-to-end and end-to-side anastomoses. 4. Changes of the internal diameter in anastomosed vessels showed luminal narrowing in the vessels at the third postoperative day and still narrowing at the second and third postoperative week in the end-to-end anastomoses. However, initial postoperative widening continued into the third postoperative week in the end-to-side anastomoses. The authors got a high success rate of anastomoses of very small arteries approximately 0.25 mm in external diameter, by developing a method of using an ordinary microscope and instruments, 11-0 nylon suture, and the administration of ticlopidine hydrochloride which is a more powerful anticoagulant than aspirin-persatin.

관골골절의 새로운 외부견인법

전대우,한기환,강진성 大韓成形外科學會 1989 Archives of Plastic Surgery Vol.16 No.5

In the modern era of increasing motorization and industrialization, traffic and industrial accidents are becoming more frequent and serious, which in turn have brought about an increase in facial bone fractures and the pattern of fractures have become more compound and comminuted. The malar eminence is so prominent in oriental people that the zygomatic bone is more frequently fractured than other facial bones. Even a markedly depressed zygomatic fracture can be well reduced with three point interosseous wire fixations including a zygomaticomaxillary buttress, a late depression of the malar eminence occurs frequently due to the pull of the masseter muscle. In order to antagonize the pull of the masseter muscle the authors have devised a new method of external traction using an Ⅳ pole and weights which were all available on the wards. Fifty-seven patients who were admitted at Keimyung University Dong-San Medical Center from November 1987 to August 1988, were treated with 3 point interossous wire fixations and myotomy of the insertion of the masseter muscle. Of the 57, 32 were then managed with the authors' external traction method and the remaining 25 were managed with external traction using Georgiade's halo apparatus. The following results are obtained by comparing our method to Georgiade's : 1. Although the authors' external traction method tends to produce a slight overcorrection(P〉0.05), the results should be improved with experience. 2. Advantages of the authors method are as follows: 1) There is no cost because all needed equipments are obtainable on the wards. 2) The traction apparatus can be easily assembled. 3) It does not annoy the patients and does not necessitate scalp wounds. 4) It is useful for treatment of the patients who have concomitant cranial or cervical bone fractures. 3. Disadvantages are: 1) The authors method is contraindicated in the patient who is not cooperative because the direction of traction can be varied. 2) There is a brief limitation of sustained traction whenever the patient is moved. In summary, the authors external traction method using an IV pole and weights can be used alone and/or as aid to Georgiade's halo apparatus in the post-operative management of depressed zygomatic fractures.

Endometriosis is the abnormal growth of endometrial tissue outside the uterine cavity. Endometriosis in the abdominal scar following cesarean section is very rare condition among the extrapelvic endometriosis. The frequency of abdominal wall endometriosis secondary to cesarean section is from 0.03% to 0.8% in some reports. It is difficult to diagnosed in spite of the typical symptoms. The typical symptom is aching swelling in the area of the surgical scar, which is influenced by the phases of menstruation. The definitive diagnosis is established by pathologic analysis. Surgical excision remains the treatment of choice. The majority of patients presented from 1 to 2 years after the precipitating operation. We experienced an unusual case of abdominal wall endometriosis presented over 10 years after cesarean section, who was admitted to our hospital complaining of recurrent left lower abdominal pain. So, we report this case with a brief review of the concerned literatures.

Aortic transection or interruption is a rare condition which developed after an acute deceleration injury. Its occurrence depends on the location and direction of the force applied and is usually from motor vehicle accident or falling down. The exact incidence of aortic transection in trauma is not known but, when develops, only about 10-15% of the victims can survive and be transported to the hospital. Even in the survivors, majority of them will be fatal within a few days if a prompt diagnosis and surgical treatments are not made. Aggressive diagnostic work-up is recommended for the patients with high suspicious index, which would salvage the victims with this fatal condition. We report the experience of two cases of aortic transection or interruption following motor vehicle accidents.

Objectives : The purpose of this study is to analyze sleep habit and investigate the association between insomnia and demographic, health and psycho-behavioral symptomatology in Korean urban elderly Method : A total of 723 community residents aged 65 years or older were surveyed by two stage, random cluster sampling method. The response rate was 76.2%. Interviewers performed door to door visits and administered a questionnaire about sleep, past medical history, and several scales as the Psychogeriatric Assessment Scale(PAS), the short form Quality of Life Scale (SF-36) and etc. Results : The mean scores are as follows : retiring time was ten-sixteen p.m., wake-up time was five twenty two a.m., duration of sleep was seven hours and six minutes. Among the elderly, 11.6% and 14.8% of the subjects reported chronic and intermittent difficulty in sleeping, respectively. The patients with back pain and history of stroke complained of more insomnia symptoms in univariate analysis. In ANCOVA analysis, insomnia symptoms were associated with an old age, depressive symptoms in male. Bodily pain and history of dermatologic disease were additional risk factors in female. Conclusions : The data suggest insomnia is one of most common health problems among elderly Koreans living in the community. Strong positive relationship between depressive symptoms and insomnia were found. Further research is needed to explore the causal relationship between insomnia and risk factors.

본 연구는 중증장애인의 고용 확대를 위해 자립생활센터가 하고 있는 일을 조사하고, 이것이 중증장애인 고용과 관련하여 시사하는 바를 분석해 보고자 하였다. 이를 위하여, 본 연구는 자립생활센터의 중증장애인 고용 실태와 장애인 고용지원 서비스의 실태에 초점을 두었다. 조사는 20개의 자립생활센터에 대한 전자우편 설문과 직접 면접을 통하여 2006년 7월부터 8월까지 2개월 동안 진행되었다. 연구 결과에 따르면, 자립생활센터는 장애인, 특히 중증장애인의 고용에 있어 적극성을 보였다. 자립생활센터에 고용된 중증장애인들의 근속기간도 길게 유지되는 것으로 나타났다. 자립생활센터의 중증장애인들은 근로자로서의 신분을 지니면서 다양한 내용의 직무를 수행하고 있었다. 또한 자립생활센터는 장애인에게 취업 전 지도 및 교육 서비스를 비롯한 고용지원 서비스를 제공하고 있었다. 이에 자립생활센터의 중증장애인 고용과 고용지원을 촉진하기 위한 방안을 제시하였다. This study intended to examine what independent living centers (ILCs) were doing to increase the employment of people with severe disabilities and intended to analyze what the roles of ILCs suggested with reference to their employment. For that purpose, the study focused on the state of employment of people with severe disabilities in ILCs and on the state of employment-support services for people with disabilities. Data collection was conducted for two months from July to August 2006 through e-mail questionnaires to and in-person interviews with 20 ILCs. The findings indicated that ILCs were very active in employing people with disabilities, more particularly people with severe disabilities. Employees with severe disabilities have served in ILCs for a long time. People with severe disabilities in ILCs were carrying out their various duties as employees. Also, ILCs were providing employment-support services, including pre-employment coaching and training services, to people with disabilities. Hereupon, the study came up with several suggestions to promote the employment of people with severe disabilities in ILCs and to expand employment-support services for people with disabilities.
