건축에서의 전문가 시스템은 설계자에게 많은 가상적인 해결안을 반복해서 수집해야할 수고를 줄여주고 모델링이나 정보제공과 같은 정형적인 측면과 설계의 판단, 상황별 특성과 같은 비정형적인 측면을 연결시키는 도구로 작용한다. 본 연구는 고층사무소건물의 설계과정 중 매스 구성 단계에서 중요한 역할을 하는 요소를 찾아내고, 그 요소들의 정형화 및 표준화 작업을 통해 고층사무소건물의 매스구성을 보조하는 전문가 시스템을 개발하는데 그 목적을 두었다. 본 연구에서 얻어진 결론을 요약해보면 다음과 같다. 건축설계작업 중 매스구성 단계를 제한조건을 만족시켜나가는 제한조건 만족모델로 인식할 수 있었으며, 이 제한조건의 일부를 체계화하여 건물의 매스구성을 보조할 수 있는 시스템을 개발하는 것이 가능하였다. 또, 개발된 시스템을 실제 사례를 통해 평가해 본 결과 타당성 있는 결과물을 산출할 수 있었다. In architecture, the expert system helps architects reduce unnecessarily repeated process. It also serves as a tool of linking patterned processes such as medeling and information provision, with unpatterned processes like decision-making process which can produce different results depending on the situation. This study is devoted to develop an expert system which is helpful to find out the important factors in massing process and to assist the massing of high-rise office buildings through patternization and standardization. The conclusion from the study as follows; It is definitely possible to make the expert system recognize the massing process as a process of meeting all the constraints on a step-by-step basis. So, the developed expert system can assist the massing process by systemizing parts of the constraints. It also proved that the developed knowledge-based system can produce proper outputs as its test showed during the study.

The most common disease of in-patients was pneumonia(8.1%) followed by neonatal hapoxia, prematurity, and acute gastroenteritis. The most common organ system(disease category) was neonatal diseases(26.4%) followed by respiratory diseases(17.4%) and infectious diseases(11.9%). 5. Average duration of admission was 10.9 days. That of Pediatrics was 10.2 days, Dermatology 7.0 days, Rehabilitation Medicine 43 days, Neurology 12.8 days and Psychiatry 20 days.

In the upper gastrointestinal tract, in particular, there are parts consisting of esophageal sphincter muscles to carry out physiologic functions, which causes impairments when removed, as well as such complications as mucosal injuries, bleeding and even perforations in the case of foreign bodies with large size and/or sharp angles. Therefore, it is essential to use an appropriate type of supplementary instrument for a safe procedure. Frequently utilized supplementary instruments are overtube, protector hood, latex glove and transparent cap. We report a case in which authors were successful in removing a watch bend consisting of metal ring from gastric body while using a modification of a widely available drip chamber of fluid set attached to vertical end of endoscopic device.

Background : Medical equipments take a very important role in diagnosis and treatment of disease in modern medicine and effective maintenance of the equipments is a necessory to provide a good healthcare to the public. After developing a new QC program for effective maintenance of medical equipments and practicing it for a year, we report the results of the new program. Methods : The maintenance data of 9 equipments in 8 categories including a CT Scanner were analyzed with regard to the parts responsible for most frequent failure and cause of the failure. After learning the most frequent failure part and cause of the failure, we developed a new QC program that emphasizes preventive maintenance of the most frequent failure part. We compared the number of failure per year and active rate of each equipment before, and after the adoption of the new QC program. Results : The average number of failure per year per equipment was 20.7 before and it decreased by 43% to 11.9 after adoption of the new QC program. The average active rate of the equipments was 92.6% before and it increased by 3.2% to 95.8% after adoption of the new program. Conclusions : The practice of the new QC program appears very useful as it decreased the failure rate and increased the active rate of the equipments.

Various surgical approaches to the orbits have been used. But the transconjunctival approach, also called the inferior fornix incision, provides adequate access to the orbital floor with esthetic results. Additionally, transconjunctival approach with lateral canthotomy allows more wide surgical field and good access to the orbital area. Generally, preseptal approach is more used rather than postseptal approach in the transconjunctival incision for the prevention of fat herniation during surgery. There are some complications in transconjunctival approaches but these complications can be prevented with careful surgical techniques. We report clinical results in 12 patients who were treated by preseptal transconjunctival incision with lateral canthotomoy for the treatment of orbital trauma. We were satisfied with this technique for reduction and reconstruction of the orbital trauma and we could also observe relatively good esthetic results.

Child is not little man but rather a father of man. Children are faced to surgical and medical problems reqiring various specialists. Authors analized 1126 pediatric surgical in-patients of Chung-nam National Univ. Hospital from Jan. to Dec. 1988 by departments, age, sex, duration of admission and types of diseases in order to get the information for management of children’s hospital. The results are as follows: 1. Absolute numbers of in-patients by departments are above 200 in general surgery and opthalmology, between 100-199 in plastic surgery, ENT, chest surgery and below 99 in urology and neurosurgery. 2. Male to female ratio as a whole is 1.8:1, male dominant. 3. Duration of admission within 1 week was of 55% as a whole, 87% in ENT, 85% in ophthalmology, 13% in orthopedic surgery. 4. Average duration of admission was 10.8 days as a whole, 4.6 days in ENT, 5.1 in ophthalmology, 29.7 days in orthopedic surgery, and variable by types of diseases. 5. The most frequent disease by departments was hernia in general surgery, fracture in orthopedic surgery, cerebral contusion in neurosurgery, ventricular septal defect in chest surgery, strabismus in ophthalmology, tonsillitis & adenoiditis in ENT.

Bipolar disorder, like epilepsy and migraine, is episodic in nature and psychiatric illness requiring lifelong treatment. So, it should not be surprising that anticonvulsants such as carbamazepine and valproate have proven efficacy as mood stabilizers. The newer anticonvulsants such as lamotrigine, gabapentin, topiramate, oxcarbazepine, tiagabine, and zonisamide may also be effective treatments for bipolar disorder. Identifying an anticonvulsant for use in bipolar disorder should take into account not only the pathophysiology of bipolar disorder but also the mechanism of action of the anticonvulsant. Evidence for effectiveness of these novel antiepileptic drugs in treating acute mania and depression as well as in preventing the recurrence of mania and depression is reviewed. In conclusion, although the novel anticonvulsants appear to be clinically useful, more controlled trials are needed to assess the effectiveness in bipolar disorder.

Thirty children with respiratory tract infections, 17 with acute and chronic bronchitis, 5 with sinusitis, 4 with rhinitis, 3 with asthma, 1 with tonsillitis, were given Broncho-vaxom^?? one capsule per day on an empty stomach for 1 month to evaluate the efficancy of the drug on acute and chronic respnatory tract infections in children. After the medication, we observed the changes of clinical symptoms, and side effects. The results are as follows; 1. The symptomatic improvements after Broncho-vaxom^?? administration were as follows; expectoration(80%), fever(72%), rhinorrhea(67%), hoarseness(67%), and coughing(65%). 2. Combined treatment with antibiotics was necessary in 19 cases(63%). 3. The degree of response were observed as mild improvement in 3 cases(10%), moderate improvement in 13 cases(84%), and excellent improvement in 1 cases(47%). 4. The side effect of Boncho-vaxom was not observed during this study.
