          대전광역시(1989~1996)의 인구증가율은 3.34%이나 자동차 증가율은 22.5%로 인구증가율을 훨씬 상회하며 자동차 보유는 4.4인당 1대꼴인 30만대에 이르게 되었다. 대전광역시는 1989년 1월 충청남도에서 분리 광역시로 승격되면서 시세가 확산되어 단핵도시에서 다핵화되었고 구도심권은 개발이 침체되면서 건축물 부설 주차장의 확보가 어려워지고 특히 필지당 평균면적이 200m²정도로 개발에 따른 주차장 확보나 이용이 용이하지 않을 것으로 판단되어 주차수요를 충족하기 위한 별도의 대책이 요망되고 있다. 주차시설 부족은 구도심의 집 · 분산도로와 구획도로를 주차장화 하게되었으며 이로인해 교통소통은 더욱 어려워져 이를 해소하기 위한 방안이 요구되고있다. 대전광역시에서는 이와같은 주차장난을 최소화하기위해서 주차장정비 기본계획에서 공공용지 지하에 주차시설 공급계획을 제시하고 있어이를 계획적으로 사업을 시행하기 위해서는 사업타당성 여부를 검토할 수 있는 경제성 분석이 요구되므로 본 연구는 이를 분석하여 경제적인 주차시설의 계획과 건설의 틀을 마련하는데 그 목적을 두고있다.

          치매노인 보호자의 부양스트레스가 자살생각에 미치는 영향

          정화철(Hwa-Cheol Jeong) 한국콘텐츠학회 2017 한국콘텐츠학회논문지 Vol.17 No.11

          본 연구의 목적은 치매노인 보호자의 부양스트레스가 자살생각에 미치는 영향에서 보호요인인 자기효능감의 매개효과를 검증하고, 이를 바탕으로 사회복지적 함의를 제시하는 것을 목적으로 한다. 이를 위해 주간보호센터 및 치매지원센터를 이용하는 치매노인의 보호자 중 자녀 및 며느리 341명을 대상으로 자기보고식 설문조사를 실시하였고, 본 연구에서는 불성실한 응답을 제외한 326명을 최종 분석에 사용하였다. 연구의 가설을 검증하기 위하여 빈도분석, 기술분석과 회귀분석을 사용하였다. 그 결과, 조사대상인 치매노인 보호자의 32.6%가 최근 1년간 자살생각을 경험한 적이 있다고 응답하였다. 그리고 보호자의 연령, 성별, 학력, 직업유무, 건강상태, 생활수준 정도 및 치매노인의 인구학적 특성과 등급, 유병기간을 통제한 상태에서 회귀분석을 실시한 결과, 부양스트레스는 자살생각과 정적인 영향관계가 있는 것으로 확인되었다. 또한, 보호자들이 지니고 있는 자기효능감은 부양스트레스와 자살생각간의 관계를 부분매개 하는 것으로 확인되었다. 이를 토대로 하여 치매노인 보호자들의 정신건강을 회복시키기 위한 각종 정책과 사회복지적 개입의 필요성, 자기효능감을 향상시키기 위한 가족 및 대인관계 개선 프로그램 강화 등을 제언하였다. The purpose of this study is to examine the effects of care-giving stress of dementia elderly on the caregiver’s suicidal ideation. In addition, mediating effect of self-efficacy was examined. In order to accomplish these purposes, a total of 336 who are caregivers of dementia elderly using self-report questionnaires. In this study, 325 elderly patients were used for final analysis. Date were analyzed by frequency and descriptive analysis, regression model analysis with SPSS 22.0. The analysis result of dementia elderly caregiver’s symptoms showed that prevalence of suicidal ideation were 32.6%. Regression analysis was conducted under the control of dementia elderly’s disease period, ratings, general characteristics and age, sex, educational background, occupation status, health status, living standard level of caregivers who were the subject of the survey. As a result, it was confirmed that the care-giving stress had a statistically significant effect on suicidal ideation. Also, the self-efficacy of caregivers was found to partial mediate the relationship between care-giving stress and suicidal ideation(***p< .001). Based on this result, I suggested the various policies and the necessity of social welfare intervention to restore the mental health of caregivers of the elderly with dementia.

          Thalamonal, Ketamine 점적, N2O 및 근이완제에 의한 기관내마취

          정원,오흥근,정화,나계환 대한마취과학회 1979 Korean Journal of Anesthesiology Vol.12 No.3

          The dangers of explosion hazards and operation theater contamination by inhalation anesthetics have led to a renewed interest in intravenous anesthesia. without intubation. We have reported clinical studies of Thalamonal-ketamine anesthesia under room air breathing in non-abdominal surgery in a previous paper that discussed advantages, disadvantages and usefulness. Now, we report Thalamonal-N₂O-Ketamine anesthesia with a microdrip technique and intubation in 63 patients undergoing various operations. These patients were divided into three groups by operation site: Group 1-upper abdominal, Group 2-lower abdominal and Group 3-non-aMominal surgery. These groups were subdivided, by muscle relaxants used, into pancuronium, d-tubocurarine and no relaxant groups. To minimize potential cardiovascular stimulation and postoperative sequelae, ThalamonaI was used at the beginning of anesthesia. The results were as follows: 1) The average duration of anesthesia was 153.9 minutes. The duration of anesthesia was 217.9 minues in Group I, 121.9 minutes in Group 2 and 152.1 minutes in Group 3. 2) The average dose of ketamine-during induction was 1mg/kg/19 minutes. The average maintenance dose of ketamine was 1.8mg/kg/hr, 2.3mg/kg/hr in Group 1, 1.6mg/kg/hr in Group 2 and 1.8mg/kg/hr in Group 3. 3) The order of frequency of administration and total dose of pancuronium and d-tubocurarine was Group 1, Group 2 and Group 3. 4) The changes in vital signs after intubation and during anesthesia were insignificant clinically. 5) The average duration required from the end of operation to extubation was 10 minutes. 6) Arterial blood gas study performed preoperatively, during operation and in the recovery room in 11 patients revealed no significant changes. 7) The postanesthetic complications were pleasant dreams 18% (11), unpleasant dreams 6% (4), emergence delirium 3% (2), vomiting 6% (4) and shivering 3% (2).

          대장암에서 폐색이 예후에 미치는 영향

          정화,정상훈,김재황,심민 대한대장항문학회 2008 Annals of Coloproctolgy Vol.24 No.6

          Purpose: An obstructed colorectal cancer (OB) has a poorer survival than a non-obstructed cancer (NOB). This study examined the prognostic impact of bowel obstruction on colorectal cancer. Methods: From December 1999 to December 2005, patients undergoing single stage operation for OB were examined prospectively. OB (n= 193) was compared with a NOB (n=444) used in a primary tumor resection during the same period. 637 colorectal cancers were examined in this study. Results: The overall operative mortality was 21 (3.3%) and the postoperative mortality was significantly higher in the OB (OB: 16, 8.3%) group than in the NOB (NOB: 5, 1.1%) group. The proportion of OB was higher in the left-colon (52.8%) than in the right colon (16.0%) and rectum (31.1%, P<0.001). However, OB was associated with an older age (P=0.013). The proportion of advanced tumor stage was higher in OB (II: 35.8%, III: 39.5%, IV: 24.7%) than in NOB (II: 53.2%, III: 35.8%, IV: 11.0%, P<0.001). The 5-year cancer-related survival for OB was worse than NOB (OB: 77.3%, NOB: 57.8%, P<0.05). However, in the cases of a colorectal cancer performed curative resection (stage II and III), the survival for OB was not worse than NOB: stage II (OB: 82.8%, NOB: 92.2%, P=0.24), stage III (OB: 65.2%, NOB: 56.9%, P=0.43). Conclusions: OB has older and more advanced disease characteristics. However, if an oncologically curative resection is performed, the survival for OB is similar to that of a NOB.
