The purpose of this study was to analyze the relationship of the socio-economic characteristics and utilization patterns of visitors with visiting motivation and satisfaction degree. For this study, socio-economic characteristics, utilization patterns, visiting motivation, expectation and satisfaction in facilities and service of recreation forest were analyzed over the spring season's visitors. Likert scale was used to investigate visiting motivation, expectation and satisfaction. And their visiting motivation for the recreation forest was analyzed with Factor Analysis, and their expectation and satisfaction for the recreation forest with the Importance-Performance Analysis(IPA). The most of visitors were under 40's age group, high education level, versatile occupations, city residents, and visited and over-night stayed more than once a year. The Factor Analysis of visiting motivation showed six factors like 1) mental and physical health, 2) stress relief, 3) nature-friendliness, 4) escaping from the daily life, 5) self-reflection 6) friendship. The IPA revealed the management situation of Mt. Keumwon Recreation Forest is going well overall, and management target had to be concentrated 3 variables like information service, the service quality of managing staffs and safety facilities in site. Finally, the research results presented that the main factors to affect the visiting motivation besides satisfaction degree were the age and education level of visitors.

We report a case of acute Wernicke encephalopathy in which diffusion-weighted imagings (DWI) revealed symmetrical high signal intensities in the medial thalamus, bilateral hemispheres of the cerebellum and periaqueductal gray matter. Calculation of the apparent diffusion coefficient demonstrated a mildly decreased diffusion on the affected regions. The high signal lesions were slowly resolved on the acute phase follow-up images with the administration of thimaine. We propose DWI should be included in the imaging protocols of patients suspected to suffer from Wernicke encephalopathy.

The purpose of this study was to investigate factors and variables which have significant effects on satisfaction of urban pedestrian sidewalk in taejon city, and to suggest basic information for urban pedestrian sidewalk. These works consist of two phase; The first, tested the user's degree of satisfaction for 37 spots of pedestrian sidewalk slide and then selected 10 spots slide by the stratified random sampling method. The second, analyzed factors and variables of satisfaction of urban pedestrian sidewalk using the semantic differential scale method, and then processed by mean score, correlation, factor analysis, multiful algorithm. The results were summarized as follows; 1) The relationship between the man group and the woman group was highly correlated as well as between the student group.1 and the student group.2 hense these groups statistically showed no difference in satisfaction ratings. 2) Pedestrian sidewalk width, cleanness, pavement materials and construction condition can be significant variables of satisfaction of urban pedestrian sidewalk. 3) Factors covering the satisfaction of urban pedestrian sidewalk have been found to be Environment of pedestrian sidewalk, Vegetation of pedestrian sidewalk and Form of pedestrian sidewalk. By using the control method for the number of factors, C.P. has been obtained as 62.8%.

Background : This study was designed to identify overtransfusion- triggering clinical factors in patients undergoing total hip replacement surgery. Methods : The discharge hematocrit was chosen for evaluation. Estimated red cell loss for each patient during the admission was calculated by the differences between admission and discharge hematocrit, multiplied by patient whole blood volume. Total RBC lost was then determined by the sum of RBC volume lost plus the RBC volume transfused. RBC volume in each patient at admission. Comparison of transfusion practice was done on the basis of sex, age, preoperative hematocrit, surgical procedure and anesthetic method. Results : Forty-six (37.7%) of 122 patients were identified to have been transfused with red cell volumes in excess of red cell volumes lost. Significant differences for patients transfused in excess of needs were found by sex (52.4% of women vs. 22.0% of men, P = 0.001) and by preoperative hematocrit (71.4% of patients with lower hematocrit vs. 24.1% of patients with higher hematocrit, P = 0.001). Conclusions : Preoperative hematocrit and sex can be a overtransfusion-triggering index. (Korean J Anesthesiol 2002; 42: 167~171)

아파트는 주변건물과의 부조화로 인해 도시경관을 파괴시키고, 획일적인 건물형태와 배치로 인하여 단조로운 공간을 형성하고 있다는 지적과 노약자에게는 불만족스러운 주택 유형이라는 평가를 받아오고 있다. 그러나 최근의 아파트는 이러한 평가와 달리, 환경 친화적 개발을 표어로 에너지가 절약되고 부하가 없는 자연 아파트, 생태 아파트, 전원 아파트 그리고 미적으로도 아름다운 공원 같은 아파트로 변해져가고 있다.<br/> (본문중에서)
