Diabetic foot ulcer and necrosis is noted among a lot of diabetus mellitus patients and become important reason for foot amputation. Diabetic gangrene is result from impairment of blood circulation or infection, and so the patient feels a severe pain and it develops sepsis follows by cause of death. Femoral angiography is the most accurate the diagnostic method for peripheral vascular disease and it can find out the level of obstruction and possibility of operation for collateral circulation. The author analysed the age, sex, blood sugar levels, duration of development of gangrene, duration of treatment, external wound of site of diabetic gangrene, femoral angiographic findings, wound culture, treatment and clinical course among 31 cases of 31 patients. Ages of patients were between 43years to 82years old and there are 21 men(70%) and 8 women(30%). Fasting blood sugar for the patient were ranging from 51.5mg/dl to 387.3mg/dl and 32.3% of patients were found between 101mg/dl to 150mg/dl. Duration of diabetic foot gangrene had ranged from 2years to 30years and 38% of patients developed between 6years to 10years Duration of treatment had ranged from 3days to 7months and 29% of patients treated between 2months to 3months. Site of diabetic gangrene at lower extremity were phalangeal area 83%, heel area 3.2%, foot dorsal area 3.2%, foot plantar area 3.2% and from these results phalangeal area were revealed the most. The most frequent obstruction level was posterior tibial artery on femoral angiography. The wound culture of the gangrene site has tested 20 cases of patient and the results 30% of Staphylo coccus aureus and Enterococcus faecalis in 10% of cases. Conservative treatment was underwent in 25.9% of patients, amputation in 51.7%, vascular bypass graft in 9.6%, skin graft in 3.2%, and debridement was done in 6.4% of patients

A model- reference adaptive controller has been designed on the model that is obtained through off-line System Identification. It is illustrated by computer simulations that the proposed control system gives good performances in the trajectory tracking control and adaptation to parameter variation.

인터넷 사용과 청소년의 생활만족 : 학교효과의 다수준분석

서우석 한국정보사회진흥원 2004 정보화정책 Vol.11 No.2

본 연구는 2003년 전국 30개 고등학교에서 조사된 학생들의 자료를 이용하여 인터넷 사용이 청소년의 일상생활 만족에 어떻게 영향을 미쳤는지를 파악하였다. 청소년의 인터넷 사용에 관한 선행연구가 주로 정보화의 부정적인 영향에 관심을 기울였던데 비해 본 연구에서는 인터넷 사용의 영향을 포괄적으로 파악하고자 하였고, 청소년의 사회적 환경으로 가족의 영향을 강조했던 선행연구들과는 달리 학교의 집단적 특성이 미치는 영향에 초점을 맞추었다. 위계적 선형모형을 통한 다수준분석 결과, 인터넷을 오래 사용하는 경우 사용시간의 증가가 생활만족에 부정적인 영향을 미쳤으며, 인터넷 활용능력의 자신감은 일반적으로 생활만족 수준에 긍정적인 영향을 미치는 것으로 나타났다. 또한 이러한 영향의 정도는 학교의 사회경제적 특성에 따라 다르게 나타났다. 학생들 가운데 화이트칼라 아버지의 비율이 높은 학교일수록 인터넷 사용시간의 부정적 효과와 인터넷 활용능력의 긍정적 효과가 큰 것으로 나타났다. 본 연구의 결과는 청소년의 인터넷 사용에 대한 연구에서 연구관심이 개인과 가족 수준을 넘어 학교로 확장될 필요가 있으며, 효과적인 정보화 정책 수립을 위해서는 사용자의 사회적 환경을 보다 폭넓게 고려해야 한다는 점을 시사한다.

The purpose of this study is to create data so that unevaluated spaces can be evaluated to resolve the uncertainty arising from the spaces excluded from evaluation due to the absence of a cooling/heating system, such as apartment housing or tenant space, when certifying the energy efficiency of a building. Therefore, the main cooling system was investigated for apartment housings and the main building usage and the main cooling and heating system were investigated for tenant spaces. Accordingly, data was created by checking the ECO2 input data, which is the main program used to evaluate the energy efficiency of a building. Its error rate was verified through comparison with the case of a building energy efficiency rating to verify the created data. As a result, the apartment housing data was calculated with an energy consumption of about 7%, and the tenant space data was calculated with an error rate of 10% and a confidence level of 90%. Regarding apartment housings, the air conditioning days are different for each region and it is judged that a deviation occurred because the energy consumption was calculated based on the data of the minimum consumption efficiency standard. In addition, regarding tenant spaces, it is judged that an error occurred because the load calculation criteria are different depending on the characteristics of a space within the neighborhood living facilities. Therefore, it is believed that the application of data created in this study will contribute to the improvement of building energy efficiency certification system.
