This study aims to analyze and compare the difference of preference to realistic and fantastic expressions presented in the illustrations of children's picture books. The subject of this study is set for 52 seven-year-old kindergarten students, including 26 boys and 26 girls, in Cheonan. Two times of researches on their preferences were made on the basis of data collection through individual interviews and self-regulatory questionnaires. A children's picture book, which best demonstrates both realistic and fantastic expressions, was selected as a research tool for such questionnaire from the ones produced and printed within Korea, which either are listed in the Recommended Book List of Children's Book Research Association or received any international award. The result shows that both boys and girls prefer fantastic expressions to realistic ones. It was also found that girls tend to prefer realistic expressions that the boys do. Nevertheless, there definitely was a limitation in thorough analysis by region or age, as they tended to show different responses when they were provided with a picture book with similar theme and story, but different form of expression.

This research is based upon the nursing statistical data published by the Institute of Nursing Policy in 2007, on behalf of Korea nursing association. We analyzed the problems on the healthcare human resources supply in Korea. We suggest that a solution is to adopt immigration policy for foreign workforce employment. The result of the research shows that more than 1,000 nurses are registrated every year except for 2004, according to the yearly status of healthcare jobs. The variance of doctors' registration was quite significant. Compared to 750 registrations in 2004, 4000 doctors were registered in 2002. The healthcare accounts for the property of citizens in terms, which represents the health and lives of everyone, so the country must take all measures to supply the healthcare services in need. Focusing on the underdeveloped region where it is difficult to approach the medical services, the foreign workforce could be added into the healthcare profession field. We conclude that employing foreign healthcare professionals will contribute to the improvement of lives in those people living in underdeveloped region, as well as unity of the local community.

Purpose : This study was conducted to estabilish the prevalence, clinical features and relationship between ECG findings and echocardiographic findings of Wolff-Parkinsion-White(WPW) syndrome in asymptomatic preschool children. Methods : An electrocardiographic screening study was performed on 77,824 preschool children in Jeonbuk province from April, 1999 to August, 2001. Patients with WPW syndrome underwent echocardiographic study. Results : Twenty three patients with WPW syndrome were discovered by electrocardiographic screening of preschool children. The prevalence rate was 2.9 per 10,000 preschool children and there was no significant sexual difference. Two patients had a history of symptoms related to tachyarrythmia. According to the ECG classification of Rosenbaum et al., five patients were type A and 18 were type B. Utilizing the criteria of Gallagher et al, right anterior, 12 patients; right anteiror paraseptal, four patients; left anteiror, three patients. Nineteen of 23 patients underwent echocardiographic study. Four of five patients with type A WPW syndrome had abnormal early systolic anterior motion of left ventricular posterior wall. Twelve of 14 patients with type B had abnormal interventricular septal motion characterized by early sytolic posterior motion immediately after inscription of the delta wave. Conclusion : The prevalence rate of preschool children in Jeonbuk province was 2.9/10,000. By the classification according to the electrocardiographic findings, the accessory pathway location was dominant right side than left side. In the echocardiographic study, type A WPW syndrome showed abnormal left ventricular posterior wall motion and type B WPW showed abnormal interventricular septal motion.

Management of the small lower ureteral stone has been attempted by either transurethral manipulation or expectant therapy. To date, however, the choice of proper method has depended mostly on clinician's preference, and the effectiveness of the transurethral stone manipulation has remained controversial Herem we evaluated the effectiveness of the transurethral stone manipulation, using with the Dormia dislodger, in 37 patients with lower ureteral stone less than 10mm in greatest diameter. The results are summarized as follows. 1. The overall success rate was 68% (25 of 37 patients); Immediate delivery of the stone was observed in 16 of 37 patients. In another 5 patients the stone was removed at the time when the indwelled ureteral catheter was taken out. In the remaining 4 patients the stone passed spontaneously within a week following the procedure. 2. Higher success rate was observed in smaller stone; 79% in less than 4 mm, 58% in 4-6 mm, and 33% in 6-10mm in it's greatest diameter, respectively. 3. The morbidity rate was 8.1% (3 of 37 patients); In one patient a broken basket was retained In the ureter, which was removed at the time of ureterolithotomy. In another patient a ureteral stricture requiring periodic dilation was complicated. And In the other patient persistent hematuria was observed, which was relieved by conservative management. These results suggest that transurethral manipulation might have to be initially applied to unremittingly painful patients with small lower ureteral stone.

Serous otitis media (SOM) is one of the most common otologic diseases which was first discribed by Politzer in 1869. Currentely, among many methods introduced to treat SOM, ventilation tube insertion is considered to be the most popular and standard method being used. However due to complication of it, there remains many disputable various problems. In order to review the clinical aspect of SOM and search for the effects and safety of ventilation tube, we studied 97 SOM patients, who had performed V-tube from Jan. 1981 to Feb. 1982 at ENT dept. of Severance Hospital. Analizing the clinical symptoms, age distribution, associated disease, otoscopic findings of ear drum, degree of hearing loss, hearing gain after insertion of V-tube and complications, following results were obtained. 1) As a subjective symptom, among 29 cases all patients had hearing loss, 19 cases (65.6%) had tinnitus, 12 cases (44.4%) had autophony and 10 cases (34.5%) of the patients had sensation of ear fullness. 2) In age distribution, 6 to 10 year old group was most numerous up to 42 cases (43.3%) and 20 years and over was 23 cases (23.5%) 3) In adult group SOM tend to be involved unilaterally whereas young child group had tendency involving bilaterally. 4) 49 cases (50.05%) were associated with tonsillitis and adenoid vegetation, 15 cases (15.5%) were associated with sinusitis, 4 cases (4.1%) had nasal allergy. 5) In preoperative otoscopic findings, 62 ears (47.7%) had retraction, 37 ears (23.6%) had bulging, 34 ears (21.7%) had color change, and 29 ears (19.7%) had no significant findings. 6) In characteristics of middle ear fluid, child group was tend to have mucinous content (84.2%) while adult group had serous content (62.5%). 7) Average preoperative air-bone gap of pure tone was 25.3 dB. 8) 24 ears (72.7%) had over 10 dB of postoperative hearing gain and average hearing gain was 17.2 dB. 9) There were 44 ears (28.1%) of complications. Among them 37 ears (23.6%) had infection, 3 ears had atelectasis, 2 ears had granulation tissue, 2 ears had permanent perforations. 10) Among 37 ears suffered from post-op. infection, 19 ears (51.4%) had initial infection just after insertion of ventilation tube, 18 ears (48.6%) were infected during the course of post-ventilation tube. Of 37 infected ears, 26 ears (70.3%) responded to conservative care, while 11 ears (29.7%) was cured after removal of ventilation tube.

The newly developed equipments for the early detection of carious lesion are LFD (laser fluorescence device), Ultrasonic diagnostic system, CLSM(confocal laser scanning microscopy), QLF(quantitative light-induced fluorescence) and DIFOTI (digital imaging fiber-optic trans-illumination) system. In this study, DIFOTI system and LFD were used for the detection of early enamel caries. Twenty five primary teeth extracted from twenty one children at around the dentitional exchanging period were selected as samples. The results obtained from DIFOTI imaging and LFD measurement were compared with those of CLSM and comprehensive evaluations were made for the diagnostic capacity of each device. In vitro test, 40 sample teeth with their buccal & lingual surface formed by a window of $2{\times}3mm$ in diameter were immersed in artificial demineralizing solution for the period of 4, 8, 12 and 16 days. The results obtained from the experimental groups (DIFOTI, LFD) were compared to control group (CLSM) and we have reached to the following conclusions. 1. The sensitivity and specificity of DIFOTI system operated in oral environment was 88.2% and 76.9% respectively. 2. The sensitivity and specificity of LFD measured in oral environment was 76.5% and 69.2% respectively. 3, Regression analysis on the light transparent rate of DIFOTI showed its decrease according to the length of primary enamel decalcification performed in vitro(r=-0.96, p<0.05). 4. No statistically significant difference between LFT measurement and the length of in vitro decalcification was found in regression analysis (p>0.05). 5. The correlation coefficient of DIFOTI image transparent rate and the lesion depth of CLMS was -0.6988 (p<0.05), whereas no statistically significant difference was found for LFD measurement.

Many studies have shown that there is a strong relationship between the congenitally missing primary teeth and their succedaneous permanent teeth. However, especially in case of lower anterior region, we can observe the existence of permanent teeth even though their precedent primary teeth were missed at times. The purpose of this study was to reveal the relationship between the congenitally missing primary lower anterior teeth and their succedaneous permanent teeth in Korean children. Total of 14,307 children, under 6 years of age, who attended the department of pediatric dentistry, Seoul National University Dental Hospital, Seoul, Korea from January 1st 2005 to September 5th 2008 were radiologically examined using the panoramic x-ray in order to analyze the relationship between the congenitally missing primary lower anterior teeth and their succedaneous permanent teeth. The results were as follows : 1. The prevalence of congenitally missing lower anterior teeth in primary dentition was 0.24%. The odds ratio of both the primary and permanent anterior teeth being present was 7163.5 and only the permanent anterior teeth being present was 0.79. 2. The percentage of all succedaneous permanent teeth being present was 44.12% in cases of missing lower primary anteriors. The odds ratio of at least one succedaneous permanent teeth being present in cases of bilateral primary anterior teeth missing was 1.57 times more common than in cases of unilateral primary teeth missing. 3. The odds ratio of primary missing teeth being unilateral was 2.2 times higher in females. Moreover, the odds ratio of succedaneous permanent teeth being present in cases of primary teeth missing was 2.22 times higher in males.
