This study was performed to evaluate effect on color and opacity of 3 different copy-milled In-Ceram cores by glass infiltration and porcelain veneering. Color was evaluated by the CIEL*a*b* readings were recorded with a Colorimeter, Color difference value( E*ab) was calculated and opacity was represented by the contrast ratio. The variance of each color parameter (L*, a*, b*), color difference value, and opacity change after glass-infiltrated and veneered with porcelain was compared. Three experimental groups were fabricated as follows. Group 1 (Alumina core) : 15 Alumina blanks was infiltrated with originally marketed glass (A1) and veneered with porcelain(A1) Group 2 (modified Alumina core) : 15 Alumina blanks was infiltrated with its associated glass(S11) and veneered with porcelain(A1) Groups 3 (Spinell core) : 15 Spinell blanks was infiltrated with originally developed glass(S11) and veneered with porcelain(A1) The results were as follows: 1. After glass infiltration, L* value showed decrease, a* value showed decrease only group 1(p<0.001) and b* value showed increase on group 1, increase on group 1, increase on group 2, 3(p<0.001). 2. After porcelain veneering L* value showed decrease(p<0.001), a* value showed increase on group 1, decrease on group 2(p<0.05) and b* value showed decrease on group 1, increase on group 2, 3(p<0.001). 3. E* ab between before and after galss infiltration was more than 13.77, and between after glass infiltration and after porcelain veneering more than 19.63. 4. After glass infiltration and porcelain veneering, Alumina showed the lowest L*, a* value and highest b* value among 3 different groups (p<0.05). E*ab between group 1-2, 1-3 was higher than that of group 2-3. 5. After glass infiltation, opacity showed decrease, Group 1 had the highest opacity(p<0.05), but no significant differences between group 2 and 3. Above results suggest that glass infiltration and porcelain veneering effects on color and opacity of In-Cream core, and that modified In-Ceram Alumina uses single crowns of bridges like In-Cream Spinell.

The purpose of this study was to investigate utilization and storage management practice of the frozen and refrigerated foods in school foodservice. 222 dietitians employed in school foodservice were surveyed. In school foodservice, the refrigerated stock farm products and seafoods (78.3%) were more used rather than frozen products (47.5%). According to school foodservice characteristics, the refrigerated meats including dairy products were more frequently used in elementary and middle schools than high school foodservice. On the other hand, the foodservice in high school used more frozen seafoods and processed foods than elementary school did. The data also showed a tendency for the contracted foodservice using more frozen meats and seafoods rather than refrigerated products when comparing with the self-operated foodservice. In terms of receiving conditions, storage methods and storage time, the result indicated that frozen or refrigerated products were often delivered at inappropriate temperature. Especially some products which were needed to be shipped and stored at refrigerated temperature such as mollusks, were delivered and kept at room temperature. The most frequently used thawing method were running water (56.9%), however, the frozen products were often sitted at room temperature for the purpose of thawing. According to the results, several inappropriate handling processes for frozen and refrigerated products were found in school foodservice. In order to improve handling process for frozen and refrigerated products, recognition of food handlers' weakness about storage and distribution, development of radical standards for receiving conditions, storage and thawing methods should be debated.

PURPOSE: The purpose of this study was to explore ways to define the concept of health inequality. METHODS: The concept analysis process by Walker and Avant was used to clarify the meaning of health inequality. RESULTS: Defining attributes of health inequality included differences in health status between individuals or groups, infringement of fundamental rights to health, unfair use of medical services, and social discrimination. The antecedents of health inequality included differences in demographic characteristics (age, gender, education, occupation, residential location), limitations in accessibility to health care, and social exclusion. Consequences of health inequality were increased costs for medical care, decreased health-related quality of life, and lack of ability to cope with health problems resulting in crisis situations, increases in morbidity and mortality, and shortening of life span. The concept was clarified through presentation of model, borderline, related, and contrary cases. CONCLUSION: Results of this study can be used to guide the direction of future studies through concept analysis in which conceptual attributes in the context of health inequality are examined. Also, based on the result of this study, development of standardized tools to measure health inequality is recommended as well as development of educational programs to reduce health inequalities.

Background/Aims: Colon transit time (CTT) test is regarded as the gold standard for evaluating colon transit function. Fluoroscopic defecography (FD) is a dynamic radiologic test to assess anorectal function. The aim is to evaluate the value of FD in constipated children with abnormal CTT test results. Methods: Fifty-one children (27 girls) with a mean age of 9.8 ± 3.2 years who met Rome III criteria for constipation and older than 5 years with abnormal CTT test results underwent FD. Results: Of 51 children, 27 (52.9%) showed positive findings on FD, including pelvic floor dyssynergia (PFD) (10/27, 37.0%), structural abnormality (15/27, 55.6%) (rectocele 53.3%, intussusception 33.3%, and both 13.4%), and both PFD and rectocele (2/27, 7.4%). In terms of CTT test subtype, of 35 children who had outlet obstruction type in CTT test, 19 (54.2%) had positive findings, including PFD (8/19, 42.1%), structural abnormality (9/19, 47.4%) (rectocele 55.6%, intussusception 22.2%, and both 22.2%), and both PFD and rectocele (2/19, 10.5%). Of the 16 children who had slow transit type of CTT test, 8 (50.0%) had positive findings, including PFD (2/8, 25.0%) and structural abnormality (6/8, 75.0%). Of the 6 children who had structural abnormality, 3 (50.0%) had rectocele and 3 (50.0%) had intussusception. For the 2 children (2/16, 12.5%) who had PFD, puborectalis muscle relax failure was found on FD. Puborectalis muscle relax failure was treated with biofeedback and medication. In the minor abnormalities, medication continued without additional therapeutic modalities. Conclusions FD was valuable for both diagnoses of underlying causes and interpretation of CTT test results in children with abnormal CTT test results. Therefore, this study suggests that FD and CTT tests should be incorporated into logical thinking for constipation in children.

Purpose: To measure the level of reflection, this study analyzes diaries written by third-year nursing students before and after the debriefing stage in simulation training. A qualitative study using diary entries from 15 nursing students to explore reflection depth. Methods: Students engaged in simulation training and the debriefing stage, documenting their reflections in diaries. Before and after debriefing, reflections were rated from Level 1 (reflectivity) to Level 7 (theoretical reflectivity). Results: The total number of reflection levels rose significantly from 545 to 829 post-debriefing, enhancing higher-order reflection.The shift signifies a move from superficial to deep reflection, highlighting debriefing's role in fostering critical thinking. Conclusion The findings underscore the critical role of debriefing in enhancing reflective thinking in nursing education. There is a demonstrated need for further research into the specific elements of debriefing that are most effective at promoting deep reflection. Future studies should conduct comparative analyses of different debriefing methods and approaches across various educational settings. This research could lay the foundation for designing more effective debriefing strategies that foster critical thinking and improve learning outcomes in nursing education.

OBJECTIVE: Conization is used for diagnosis and treatment of cervical neoplasia. Our purpose of this investigation is to determine the efficacy of loop conization for the treatment of cervical dysplasia and the significance of the clinical and histological factors used to predict residual dysplasia after loop conization. METHODS: We reviewed the charts of patients who were received conization and subsequently total hysterectomy at Kangnam St Mary Hospital during 1989 and 2000. Logistic regression and Chi-square test were used for analysis. RESULTS: Total 257 patients were included. The mean age of the patients was 44.7 years. Of these patients, 87 (33.8%) had residual disease in the hysterectomy specimens. Age, the involvement of cut surface of endocervix and exocervix, severity and extent of the lesion, and scattering lesion were associated with the residual disease. But preoperative HPV infection, which is known as the cause of cervical neoplasia was not associated with the residual disease. CONCLUSION: When the high risk factors are present, the validity of conservative treatment should be considered and more careful follow up with pap smear, HPV test and colposcopy is necessary. Because about one thirds of patient has residual disease after conization, LEEP conization should be used for diagnosis of cervical neoplasia rather than treatment.

The present study aimed to evaluate the psychometric properties of the Korean version of the Trauma Symptom Checklist for Young Children (TSCYC) including reliability and validity. The TSCYC is an instrument to identify trauma symptoms in children from age 3 to 12 yr by their caretakers. The Korean version of the TSCYC was administered to the caretakers of a normative group of 299 children (137 boys and 162 girls) aged 3 to 12 yr and a traumatized group of 73 sexually abused children (22 boys and 51 girls) aged 3 to 12 yr and their caretakers rated the TSCYC and the Child Behavior Checklist and the Child Sexual Behavior Inventory. Among normative group, 88 performed a re-test after 4 weeks. The internal consistency, Cronbach's alpha of total scale of the TSCYC was 0.92 (normative group) and 0.96 (traumatized group). For the nine clinical scales in the TSCYC, it ranged between 0.46-0.92 and 0.77-0.96, respectively. Test-retest correlation of the TSCYC was good (Pearson r score ranging 0.52-0.96). Correlations between the TSCYC and other measures of corresponding constructs were satisfactory. Regarding discriminant validity, the mean total score of the TSCYC was significantly higher in the traumatized children than in the normative group. This study demonstrated that Korean version of the TSCYC is a reliable measure with excellent internal consistency and good stability over 4-week test-retest interval. It can be recommended for clinicians to screen for trauma symptoms after child sexual abuse in Korean young children between the ages 3 and 12.

PURPOSE: This retrospective study was performed to identify the clinical characteristics of influenza B infection and compare to influenza A infection. METHODS: Medical records of patients diagnosed with influenza using a multiplex PCR test, admitted to Seoul St. Mary's Hospital, during the 2011-2012 influenza season were analyzed. Clinical and laboratory characteristics of influenza B patients were investigated and compared with those of influenza A patients. RESULTS: A total of 145 influenza patients were enrolled during this study period. Among these, 66 and 78 patients were diagnosed with influenza A and B, respectively, and 1 patient was diagnosed with co-existing influenza A and B. Cough (88.2%), rhinorrhea (77.1%) and sputum (60.4%) were the most common symptoms among these influenza patients, and most were diagnosed with upper respiratory infection (31.9%) or lower respiratory infection (49.3%). In comparison to influenza A patients, influenza B patients were older (4.7+/-4.1 years vs. 3.3+/-2.5 years, P=0.016), and the number of fever days before hospitalization were longer (3.0 days vs. 2.5 days, P=0.043). While sore throat (10.3% vs. 1.5%, P=0.039) and vomiting (20.5% vs. 6.1%, P=0.012) were more common in influenza B patients than in influenza A patients, other clinical and laboratory characteristics were not significantly different between the two groups. CONCLUSIONS: No significant differences in clinical and laboratory perspectives were manifested in influenza A and B infections. Preventive measures should be emphasized over treatment in influenza B due to prolonged fever duration before admission.

PURPOSE: To compare ocular biometry and refractive results measured using conventional applanation ultrasonography and 3 different optical interferometries, Lenstar LS900(R), AL-Scan(R) and OA-2000(R). METHODS: The biometries of 31 cataractous eyes were measured using ultrasonography, Lenstar LS900(R), AL-Scan(R) or OA-2000(R). The axial length, anterior chamber depth and keratometry were measured. The SRK/T formula was used to calculate intraocular lens power. Two months after cataract surgery, the refractive outcome was determined and results from the 4 different biometry methods were compared. RESULTS: Axial lengths were 23.39 +/- 0.95 mm, 23.42 +/- 0.98 mm, 23.43 +/- 0.98 mm and 23.44 +/- 0.98 mm measured using ultrasonography, Lenstar LS900(R), AL-Scan(R) and OA-2000(R), respectively with no statistically significant differences observed (p = 0.996). The anterior chamber depth and keratometry were 3.14 +/- 0.41 mm, 3.10 +/- 0.38 mm and 3.13 +/- 0.39 mm (p = 0.936) and 44.41 +/- 1.52 D, 44.54 +/- 1.57 D and 44.44 +/- 1.52 D (p = 0.937) for Lenstar LS900(R), AL-Scan(R) and OA-2000(R) respectively. There were no statistically significant differences between the 3 optical devices. The mean absolute error of the 4 different devices were not statistically significant (p = 0.722). CONCLUSIONS: The ocular biometric measurements and prediction of postoperative refraction using ultrasonography, Lenstar LS900(R), AL-Scan(R) or OA-2000(R) showed no significant differences.

PURPOSE: An optimal treatment for Helicobacter pylori (H. pylori) infection in children has not yet been established. In this study, the efficacy and the tolerability of triple therapy with colloidal bismuth subcitrate (CBS), amoxicillin and metronidazole, were evaluated in comparison with dual therapy with CBS and amoxicllin. METHODS: Eighty-six children with H. pylori infection, aged 6 years to 14 years, were enrolled in this study. H. pylori infection was confirmed by endoscopic antral biopsy with an rapid urease test, culture and a modified Giemsa stain. The children were considered positive for H. pylori infection if culture was positive or if both modified Giemsa staining and CLO test were positive. The children were treated with one of the following three regimens. Dual therapy with CBS for 4 weeks and amoxicillin for 2 weeks (Group I. n=57: 1993.8-1995.1), Triple therapy with CBS for 4 weeks, amoxcillin for 2 weeks and metronidazole for 2 weeks (Group IIa. n=11: 1995.2-1995.7), and Triple therapy with CBS for 2 weeks, amoxicillin for 2 weeks and metronidazole for 2 weeks (Group IIb. n=18 : 1995. 8-1996. 6). A 50mg/kg/d dose of amoxcillin was aclministered, and that of CBS was 7-8mg/kg/d, and that of metronidazole was 20mg/kg/d. About one month after the cessation of treatment, eradication of H. pylori was evaluated with repeated endoscopic biopsy. RESULTS: H. pylori eradication rate was 61.4% (35/57) in Group I, 90.9% (10/11) in Group IIa, and in the absence of H. pylori 88.9% (16/18) of Group IIb was done by means of an urease test, culture and a modified Giemsa stain (P=0.012). The overall proportion of eradication of H. pylori infection was 89.7% (26/29) by triple therapy and 61.4% (35/57) by dual therapy (P=0.007). However, there was no statistically significant difference in eradication rate between the 2-week triple therapy (IIb) and the Denol 4-week triple therapy (IIa)(P=0.86). Side effects : All patients in three treatment groups were tolerated well with little and mild side effects (P=0.258). CONCLUSION: The 2-week triple therapy with CBS, amoxcillin, and metronidazole would be a highly effective and safe treatment regimen for H. pylori infection in children.
