This study examined the demographic characteristics of the elderly who use public libraries in Daejoen Metropolitan City. Their tendencies in using the library level of satisfaction about the library and how the library affects their life were also evaluated. The survey revealed there were more man than woman users. And most users being relatively healthy sixties, highly educated and belonging to the middle class were indicated. They have been using the library frequently and regularly for a long time and were highly satisfied with the services from librarians and other staffs. Also the Public library services had a positive effect on the quality of the life of the elderly. As a result, an effective program for servicing potential visitors who are in poor health, over 70 years old, having lower level of education, living in below standard conditions, and living far from the library were suggested. Elderly women also will be the potential visitors.

Among the causes of childhood behavioral problems - that is, physiological, psychological, and environmental factors -, the common element of non-organic psychological and environmental factors is influences from the parents. Roles of mother who does the biggest emotional exchange with the child after birth may have substantial association with the childhood behavioral problems. In this connection, the present explanatory study was conducted for the purpose of understanding the causal structural relationship in which mother's child caring behaviors affect child behavioral problems. The data collection period was July 2 - 7, 2001. The subject was 4th, 5th, 6th graders' mothers in 4 elementary schools located in Daejoen city and 299 surveys were used in the analysis. As for the tools used in this study to assess the mother's child caring Behavior Scale by Park, Seong-Yeon and Yi, Sook (1990) was used to measure the mother's behaviors. The child behavioral problems were measured with the Korean-Child Behavior Checklist (K-CBCL), standardized into the Korean version by O, Gyung-Ja, Yi, Hye-Ryon, Hong, Gang-Eui, and Ha, Eun-Hye. For the data processing, the frequency and the percentage were calculated, and the analyses of variance, correlation were carried out. The result of this study is summarized as follows: First, the examination of the effect of mother's general characteristics on the mother's caring behavior shows that significant differences are made by the active participation (p=0.020) in the occupation, affection(p=0.000), authority control(p=0.013), achievement(p=0.030), active participation(p=0.032) in the education level, consistency regulation(p=0.007) in the religion. Second, the examination of the effect of mother's caring behaviors on the child behavioral problems shows that significant differences are made by some child behavioral problems in the affection, achievement, consistency regulation, authority control, over protection caring behaviors. Third, as for the correlation between mother's child caring behavior and child behavioral problems, a significant correlation is revealed between the negative child caring behavior and child behavioral problems.

This paper proposes a virtual target overlay technique for a realistic training simulation which projects a virtual target on ground-based CCD images according to an appointed scenario. This method creates a realistic 3D model for instructors by using high resolution GeoTIFF (Geographic Tag Image File Format) satellite images and DTED(Digital Terrain Elevation Data), and it extracts road areas from the given CCD images for both instructors and trainees, Since there is much difference in observation position, resolution, and scale between satellite Images and ground-based sensor images, feature-based matching faces difficulty, Hence, we propose a moving synchronization technique that projects the targets on sensor images according to the moving paths marked on 3D satellite images. Experimental results show the effectiveness of the proposed algorithm with satellite and sensor images of Daejoen.

Background: The aim of the present study was to identify chromosomal loci that contribute to the pathogenesis of aortic dissection (AD) in a Korean population using array comparative genomic hybridization (CGH) and to confirm the results using real-time polymerase chain reaction (PCR). Materials and Methods: Eighteen patients with ADs were enrolled in this study. Genomic DNA was extracted from individual blood samples, and array CGH analyses were performed. Four corresponding genes with obvious genomic changes were analyzed using real-time PCR in order to assess the level of genomic imbalance identified by array CGH. Results: Genomic gains were most frequently detected at 8q24.3 (56%), followed by regions 7q35, 11q12.2, and 15q25.2 (50%). Genomic losses were most frequently observed at 4q35.2 (56%). Real-time PCR confirmed the results of the array CGH studies of the COL6A2, DGCR14, PCSK6, and SDHA genes. Conclusion: This is the first study to identify candidate regions by array CGH in patients with ADs. The identification of genes that may predispose an individual to AD may lead to a better understanding of the mechanism of AD formation. Further multicenter studies comparing cohorts of patients of different ethnicities are warranted.

This research was conducted to determine heavy metal contents of soil and tree in pear orchard located near national road with heavy traffics. Topsoil (0-15 cm depth) and subsoil (15-30 cm) samples in pear orchard located within 40 m from national road had higher Pb, Cu, and Zn contents than background orchard (BG) and these heavy metal contents decreased with distance from road. Topsoil samples taken at 10 m from national road had 4 times higher level in Pb, 3 times in Cu, and 2.5 times in Zn compare to BG. The Cd contents of topsoil in orchard were higher than those of BG but were not in subsoil. Highest heavy metal contents of pear leaves in roadside orchard were 20.08 in Pb, 7.02 in Cu, 30.83 in Zn, and $1.68\;mm.kg^{-1}$ in Cd and these heavy metal contents in roadside orchard were higher than BG. Cd contents of fruit and Pb contents of fruit stalk in roadside orchard were higher than BG and these heavy metal contents decreased with distance up to 40 m from the road.

This study aimed to investigate the effects of stress and ego resilience on children's school adjustment and life satisfaction. The subjects were 339 4th-6th grade children in Chungnam and Daejoen. Data were analyzed by Pearson's correlation and multiple regression analysis. And structural equation model were used to verify the model of this study and to examine the mediating effects of ego resilience. Results were as follows: First, school adjustment and life satisfaction were correlated with stress and ego resilience significantly. Second, the model of this study fit well. Third, Ego resilience mediated the relationship between stress and school adjustment, and between stress and life satisfaction. And it moderated the effects of stress on school adjustment and life satisfaction. And the suggestions for education and counseling of children were discussed.

Background: The purpose of this study was to investigate the clinical efficacy of Korean medicine combination treatments for recurring back pain after medical procedures. Methods: This was a retrospective study performed on 311 patients admitted to Daejoen Jaseng hospital who were diagnosed with lumbar spine herniated intervertebral discs. The patients were divided into 2 groups according to whether or not they had undergone at least one medical procedure on the lumbar spine. They were assessed with Numeric Rating Scale (NRS), Oswestry Disability Index (ODI) and EuroQol-5 Dimensions Index (EQ-5D) before and after treatment. Results: Patients who experienced a medical procedure on the lumbar spine in the prehospital phase (Group A), statistically significantly improved EQ-5D and ODI scores. The NRS scores also decreased however it was not statistically significant. Patients who had not undergone a medical procedure on the lumbar spine in the prehospital phase (Group B) had statistically significantly improved ODI and NRS scores. The average EQ-5D score decreased however, there was no statistically significant difference before and after scores in Group B. There was no statistically significant difference in variation in EQ-5D, ODI, and NRS scores before and after treatment between the groups. Conclusion: The results of this study indicated that even after a bilateral procedure and surgery, when pain in patients with lumbar spine herniated intervertebral disc did not decrease, (as in failed back surgery syndrome), Korean medicine combination treatment of postoperative pain was helpful and there was improvement in daily life.

The national government, as well as many regional governments, have supported the 'Ppuri industries', and the Daejeon region is in need of developing these sectors. Various research studies have examined the ppuri industries. However, there are limited studies concerning innovative activities and difficulties in the industries. Therefore, this paper focuses on firms' innovative activities and difficulties in the ppuri industries in the Daejeon region and provides policy implications. For this purpose, we surveyed firms supported by Daejeon Technopark's Ppuri industries programs, utilizing an innovation survey questionnaire developed by STEPI. We assumed that these firms have high intention for innovation among firms in the Daejeon's ppruri industries, and tried to identify characteristics and problems of innovative activities by comparing results with those of STEPI's Korean Innovation Survey. The results show that the overall pattern of innovative activities of Daejeon's ppuri industry firms do not differ from those found in the Korean Innovation Survey. However, there are a few notable differences. The rate of aborted innovation in the Daejoen's ppuri industries was higher than those found in the Korean Innovation Survey. Lack of financing was a major factor hampering innovation. These results provide policy implications that industrial and regional characteristics of ppuri industries must be reflected in the policy, and also policy measures for lowering the rate of aborted innovation.

Purpose : We aimed to evaluate the abnormalities of chest radiographs including atelectasis in children who were admitted with bronchial asthma. Methods : We retrospectively analyzed the 357 chest radiographs and the clinical and laboratory features of the 144 children with asthma, who were admitted at Daejoen St. Mary's Hospital from April 1994 to May 1998. Results : Clinical and laboratory characteristics were as follows : male to female ratio, 2.1 : 1; mean age, 4.8 years of age; mean numbers of admission, 2.5; mean hospitalization, 5.0 days; mean IgE, 387 IU/mL; mean eosinophil count, $362/mm^3$. In the abnormal findings of the 357 radiographs, there were 314 cases(88.0%) of hyperinflation, pulmonary infiltration 35.0%, atelectasis 5.3% and pneumomediastinum 0.3%. All(19) cases of atelectasis were observed in the right lung field with mostly segmental and lobular distribution, except one with lobar involvement. Atelectasis was predominant in males and those under 2 years of age. There was a tendency that the right upper lung was more involved under two years while the right lower lung was more involved over seven years of age. Conclusion : Radiographs of children admitted to hospital with bronchial asthma showed abnormal findings including pneumonia or atelectasis(5.3%). These abnormal findings can help to determine other therapeutic modalities in addition to asthma treatment.

This study was executed to find out the intensity of turnover intention and its associated factors of radiologic technologists who worked for private clinic and university hospitals in Daejoen. Such variables as social and demographic characteristics, job-related features, job stress, job satisfaction, job performance, organizational commitment and turnover intention were investigated based on the survey of randomly sampled 400 radiologic technologists. The results are summarized as follows. 1. College graduates of private clinic workers were significantly higher than junior college graduates of them in the mean score for turnover intention. And low age groups, unmarried group, no religion group, low job career groups and low income groups of university hospital workers were significantly higher than high age groups, married group, religion group, high job career groups and high income groups of them respectively in the mean score for turnover intention. 2. Private clinic and university hospital workers' low and high groups in the variables of job demand, job control, supervisor support, job satisfaction, organizational commitment showed significant difference in the mean score for turnover intention. specially private clinic workers' low and high groups in the variables of coworker support, job performance showed significant difference in the mean score for turnover intention. 3. A hierarchial multiple regression analysis was conducted to catch the influence of related variables on turnover intention according to private clinic workers and university hospital workers. As a result of the analysis, the higher the degrees of education and job demand were and the lower the degree of job satisfaction was for private clinic workers, the higher the degree of turnover intention was. And the lower the degrees of age, job career, job satisfaction and organizational commitment were for university hospital workers, the higher the degree of turnover intention was. In conclusion, it was found that job demand and job satisfaction for private clinic workers and job satisfaction and organizational commitment for university hospital workers influenced on turnover intention.
