Aspiration of a foreign body in the airway is common cause of sudden obstructive breathing, crouping cough, hoarseness, and wheezing. Especially that caused serious problem in case of the young children. A past history of foreign body aspiration is itself an indication for bronchoscopic examination of the airway, because some children with aspirated foreign bodies are without symptoms and chest X-ray films may not show abnormalities. So the anesthesiologist should take a notice of removing foreign body in the anesthetic procedure. The author have experienced 36 cases removal of foreign bodies in the airway under general anesthesia from July, 1982 to January, 1996 in Chunan Hospital, College of Medicine, Soonchunhyang University. The results were as follows 1) Among the 36 cases, 25 cases(69.7%) were under the age of 5. The ratio of male and female was 1.8 : 1. 2) In duration of lodgement, there was most frequent within one day in 15 cases(41.7%) and the longest duration was 20 days. 3) The most common symptom, sign and auscultation finding were cough 19 cases(52.8%). chest retractions 7 cases(19.4%) and decreased breathing sound 20 cases(55.6%) 4) Abnormalities in the chest X-ray were found in 15 cases(41.7%) among 36 cases. 5) Vegetable foreign bodies, expecially peanut were the most common airway foreign body(28.7%), followed by plastic foreign body(14.4%) and mucous plug(11.3%). 6) The foreign body involved the right bronchus 16 cases(45.7), left bronchus 10 cases(28.6%), trachea 5 cases(14.3%), and larynx 4 cases(11.4%). 7) Foreign body induced complications occurred in 9 cases(25.0%); pneumonia 8 cases and pneumomediastinum 1 case, and all of postoperative complication was pneumonia(25.0%). 8) 34 foreign objects(94.4%) were removed by endoscopy but tracheostomy was required in two patients.

Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

It is thought that computer-based farm management information system is essential for making Korean agriculture internationally competitive. Unlike the management information system for the industrial manufacturing, agricultural information system should reflect natural and economic conditions in a specific region. Moreover, farm management in a specific region can be improved when individual farms could use proper information which contains social and economic conditions in that region. In this sense, the supplier of farm management information to farmers should supply realistic information that can improve management conditions for farming to farmers. This study proposes a suggestion for establishing computer-based agricultural information system for development of regional agriculture. The main contents are summarized as follows : 1. The usefulness of information system for improving regional farm management and the types of agricultural information system. 2. The establishment of supply and demand network for farm management information. 3. A direction for improving the installation methods of agricultural information system network.

김유리,민찬홍 동덕여자대학교 디자인연구소 2003 디자인포럼21 Vol.6 No.-

현재 전 세계적인 노령인구의 급격한 증가는 노인 문제를 심각한 사회문제로 대두시켰고 이는 국내의 상황과도 별반 다를 바가 없다. 이런 문제점을 해결하기 위한 방안으로 지역 주민의 노인부양을 덜어주며 노인들의 여가 생활을 지원해 사회적 격리 문제를 해결하고 정서적, 사회적 유대감을 조성할 수 있는 여건을 만들어 주는 노인 종합 복지관의 중요성이 부각되고 있다. 경제활동이 없는 노인들은 노인복지관 내 취미공간의 서비스 프로그램의 다양화와 노인들 간의 친목과 유대관계가 이루어지는 공간으로 가정에서 거주하는 시간 이외에 대부분의 시간을 복지관에서 기거한다. 따라서 실 사용자인 노인들의 시 · 지각뿐만 아니라 심리적인 영향을 고려하여 편안하고 안락한 환경을 제공할 수 있는 보호소와 여가 생활을 하는데 있어서 흥미를 유발하고 지속적인 활동이 이루어 질 수 있도록 하는 환경이 제공되어야 한다. 실내 내부 환경 요소로 작용하는 것에는 색채, 조명, 소음 등 여러 가지가 있으며 이러한 요소들은 독단적으로 영향을 주기보다는 상호 복합적으로 작용한다. 인간은 오감 중에 80% 이상을 시각적 자극에 의해 정보를 얻고 감성이 자극받는다는 사실을 미루어 볼 때 실내 환경에서 색채가 얼마나 중요한지 알 수 있다. 특히 노인은 노화와 질병으로 시 · 지각 능력이 일반인에 비해 떨어지는 것을 감안하여 시각적 만족을 주는 심미적인 색채의 사용과 색채 심리, 치료에 이용되는 색채를 복지관에 적용한다면 현 복지시설에 대한 노인들의 만족도와 이용능률을 향상시킬 수 있을 것이다. 본 연구는 노인에게 합당한 색채 환경을 제시하고자 하는 후속 연구에 앞서 서울에 있는 다섯 곳의 노인 종합 복지관을 조사 대상으로 현재의 노인 종합 복지관의 실내 색채를 조사 분석하여 노인 복지관의 실내 색채 현황을 조사 분석하여 그 문제점을 파악하는데 있다. In present, the sudden increase in old-aged population became the serious problem of the worldwide concern and same thing happens here. The general welfare institution for the aged is divided into two sections in wide view, a supporting section that lighten the local dweller's obligation of supporting and the hobby section that supporting the usage of rest of their life time. The old and retired aged people spend their almost time in the space where they can meet the others and make relationship in additional have the variety programs for their hobby life is the actual circumstance. Consequently it's environment for their comfortable living designed according to the regard of not only the old aged(real residents)'s sight and sensation but also the mental effects and environment for stimulating their interests, keeping up the activity must be offered. The fact that a human being get information and stimulates his sensitivity more than 80% from visual influence makes us to know how important the color in indoor environment is. Furthermore the old people have less sight and mental faculties compare with normal young people because of symptoms of senility and sickness. So if we consider this peculiarity and apply to welfare facilities study about color that also used to color psychology and cure then we can improve satisfaction and coefficient of utilization of the aged about welfare facilities nowadays. I checked out 5 general welfare institution for the aged to present compatible color environment to old people. This study precedes the following study which is focused on the proposal of suitable or appropriate color circumstance for old age. Upon inquire and analysis on interior color into 5 general welfare facilities for old age in Seoul, the study aims at analyzing the present status of those welfare facilities and understanding the current problem.

The present study aims to explore the effects of applying spheroid-combined stimulating therapy on body composition. For this aim. 20 persons were selected as subjects and 10 of them each were assigned to the experimental group and control group, respectively. The experimental group was applied a 12-week combined stimulating therapy and changes in physical constitution of the members were measured before application and 4, 8 and 12 weeks after application. From the study, following conclusions could be drawn: First, body weights of the experimental group decreased from 59.9kgs before application of the spheroid-combined stimulating therapy to 57.2kgs 12 weeks after application, no significant but 4.51% change. Second, body fats of the experimental group changed from 18.8kgs before application to 16.4kgs 12 weeks after application, no significant but 12.77% reduction. Third, % fats of the experimental group decreased from 31.2% before application to 28.6% 12 weeks after application, no significant change but 8.33% reduction. Fourth, body mass index(BMI) of the experimental group decreased from 23.23 kg/㎡ before application of the therapy to 21.43kg/㎡ after application, no significant but 8.03% reduction. As seen above, the 12-week application of the spheroid-combined stimulating therapy produced no significant changes in physical constitution as physical exercise did, but improved physical constitution by reducing certain amount of boy weight, body fat, % fat and BMI. In order to detect more positive and significant changes in physical constitutions, continued studies and clinical experiments should be performed to more diverse subjects using technically reinforced equipment for spheroid-combined stimulating therapy.
