OBJECTIVES: "Internet-addiction" came into common use not only in clinical setting but also in everyday life. But, pathophysiology and diagnostic criteria of the internet addiction remain unknown. Because adolescents are in developing period, they might be vulnerable to the internet addiction, depression and sleep-related problem. The objectives of this study were to investigate the characteristics of internet addiction and its association with sleep pattern and depression in Korean adolescence. METHODS: Subjects were 799 middle and high school students in Seoul, Korea. We administered a self-reported questionnaire including socio-demographic data, Korean versions of Young's Internet Addiction Scale (YIAS), Pittsburgh Sleep Quality Index (PSQI), the Center for Epidemiologic Studies for Depression Scale (CES-D) and questions about internet using patterns. Data of 696 subjects were included in analysis. Chi-square tests were used to analyze proportional differences, and ANOVA with post-hoc tests were used to analyze differences among groups. Partial correlation analyses were performed to analyze the correlation of internet addiction with other variables (two-tailed, p<0.05). RESULTS: Of the 696 participants (grade 2 of middle school;M2 135 vs. grade 1 of high school;H1 238 vs. grade 2 of high school;H2 323), 2.0% (n=14) were internet-addicted (IA), 27.7% (n=193) were over-using (OU) and 70.3% (n=489) were not-addicted (NA). The mean scores of YIAS, PSQI and CES-D scores were 35.24+/-12.78, 5.53+/-3.04 and 16.72+/-8.69, respectively. In higher grade students, average total sleep time was shorter (M2 426.20+/-67.68 min. vs. H1 380.47+/-62.57 min. vs. H2 354.67+/-73.37 min., F=51.909, p<0.001), and PSQI (4.69+/-3.14 vs. 5.42+/-3.15 vs. 5.97+/-2.83, F=8.871, p<0.001) CES-D (13.53+/-8.37 vs. 16.96+/-8.24 vs. 17.87+/-8.84, F=12.373, p<0.001) scores were higher than those of lower grade students. Comparing variables among IA, OU and NA groups, computer using time not for study (96.36+/-63.31 min. vs. 134.92+/-86.79 min. vs. 213.57+/-136.87 min., F=34.287, p<0.001) and portable device using time not for study (84.22+/-79.11 min. vs. 96.97+/-91.89 min. vs. 152.31+/- 93.64 min., F=5.400, p=0.005) were different among groups. PSQI (5.26+/-2.97 vs. 6.08+/-2.97 vs. 7.50+/-4.41, F=8.218, p<0.001) and CES-D scores (15.40+/-8.08 vs. 19.05+/-8.42 vs. 30.43+/-13.69, F=32.692, p<0.001) were also different among groups. YIAS score were correlated with computer using time not for study (r=0.356, p<0.001) and portable device using time not for study (r=0.136, p<0.001). PSQI score (r=0.237, p<0.001) and CES-D score (r=0.332, p<0.001). YIAS score and PSQI score (r=0.131, p=0.001), YIAS and CES-D score (r=0.265, p<0.001), PSQI score and CES-D score (r=0.357, p<0.001) were correlated each other. CONCLUSION: These results suggested that adolescents' internet-addiction was correlated with not only computer and portable device using time not for study but also depression and sleep-related problems. We should pay attention to depression and sleep-related problems, when evaluating internet-addiction in adolescents.

OBJECTIVE: The aim of this study is to evaluate the clinical usefulness of cervicogram as primary screening test of cervical intraepithelial neoplasia. METHODS: Total 294 women who had undergone cervicogram and pathologically diagnosed at YUMC between January and July 2003, were selected. Diagnostic accuracy of Pap smear, cervicogram and Pap smear combined with cervicogram were compared with pathologic diagnosis. Statistical analysis was performed by chi-square test (SPSS version 11.0). RESULTS: 1. Among 294 women, Pap smears were normal in 130 cases (44.2%) and abnormal in 164 cases (55.8%). The diagnostic accuracy between Pap smear and histology was as follows; sensitivity 72.0%, specificity 64.6%, positive predictive value 72.0%, negative predictive value 64.6%, false positive rate 28.0%, false negative rate 35.4%. 2. Cervicogram were normal in 202 cases (68.7%) and abnormal in 92 cases (31.3%). The diagnostic accuracy between cervicogram and histology was as follows; sensitivity 39.6%, specificity 79.2%, positive predictive value 70.7%, negative predictive value 31.0%, false positive rate 29.3%, false negative rate 49.0%. 3. Among 130 women with normal Pap smear, cervicogram were normal in 101 cases (77.7%) and abnormal in 29 cases (22.3%). The diagnostic accuracy between cervicogram with normal Pap smear and histology was as follows; sensitivity 26.1%, specificity 79.8%, positive predictive value 41.4%, negative predictive value 66.3%, false positive rate 58.6%, false negative rate 33.7%. 4. Among 164 women with abnormal Pap smear, Cervicograms were normal in 101 cases (61.6%) and abnormal in 63 cases (38.4%). The diagnostic accuracy between cervicogram with abnormal Pap smear and histology was as follows; sensitivity 44.9%, specificity 78.3%, positive predictive value 84.1%, negative predictive value 32.7%, false positive rate 15.9%, false negative rate 67.3%. CONCLUSION: Although adjunctive use of cervicogram to Pap smear in initial screening of cervical intraepithelial neoplasia showed higher specificity, higher negative predictive value and lower false negative rate compared to Pap smear alone, but, consideration in terms of lower sensitivity, lower positive predictive value, higher false positive rate and cost-effectiveness should be given in lieu of clinically applicating cervicogram with Pap smear as initial screening test.

OBJECTIVES: People at ultra-high risk for psychosis have heterogenous character and different long-term outcomes. We divided ultra-high risk subjects into two subgroups by presence of familial history and tried to find different pattern of functional connectivity of the default mode network (DMN) between the two groups in order to examine the effects familial loading. METHODS: Eleven subjects at clinical-high risk (CHR) group with familial history of psychiatric illness and nineteen subjects of CHR group without familial history were recruited. All the subjects were scanned using resting-state functional magnetic resonance imaging. A posterior cingulate cortex was the seed region of the analysis, and the DMN of the both high risk group were analyzed with voxel-wise two sample T test. RESULTS: The CHR group with familial history showed greater functional connectivity in the precuneus area in contrast with the other high risk subjects (peak-level t=5.49, p<0.001). There were no significant differences in total score on the Positive and Negative Syndrome Scale and Scales of Psychosis-risk Syndrome between the two groups. CONCLUSION: The study suggests that the abnormalities of functional connectivity between precuneus and posterior cingulate area may be associated with the genetic vulnerability of high risk trait.

The purpose of this study was to evaluate on nutrient intake status and diet quality of middle and old aged vegetarian women in Korea. The research group was composed of vegetarian women (n = 91), all of them were Seven Day Adventists, who had been on vegetarian diets, over 20 yrs. Their anthropometric measurements, dietary intakes, and diet quality indices were compared to omnivores (n = 122). The average age of vegetarians and omnivores were 61.8 yrs and 60.3 yrs, respectively. The mean daily energy intakes of vegetarians and omnivores were 1428.8 kcal and 1424.5 kcal, respectively and there was no significant difference. The vegetarians consumed significantly lower intakes of protein (p<0.05), zinc (p<0.001) and vitamin B2 (p<0.05) compared to omnivores. In the diet quality, zinc and vitamin B2 nutrient adequacy ratio (NAR) of vegetarians were significantly lower than those of omnivores. Mean adequacy ratio (MAR) of vegetarians and omnivores were 0.80 and 0.77, respectively and there was no significant difference. The KDDS (Korean's Dietary Diversity Score) of vegetarians and omnivores were 3.7 and 4.0, respectively, and there was significant difference (p<0.01). The KDQI (Korean's Diet Quality Index) of vegetarians (1.5) was significantly lower than that (2.1) of omnivores (p<0.001). In conclusion, vegetarian women have low intake status of protein, zinc and vitamin B2, and partly low diet quality. Therefore it was needed that well planed diets to replace the nutrients supplied from excluded food groups in middle and old aged vegetarian women.

PURPOSE: To describe the prevalence and severity of postneonatal epilepsy after neonatal seizures in term neonates as well as to evaluate the predictive factors of postneonatal epilepsy. METHODS: Retrospective analysis of 50 children who experienced neonatal seizures. In children with at least 12 months of follow-up data, the univariate and multivariate logistic regression analysis was applied in order to determine the predictive factors of postneonatal epilepsy. Electroencephalography (EEG), neuroimaging studies, and other clinical variables were systematically analyzed. Infants with abnormal EEG recordings in the initial studies underwent a follow-up EEG examination at 1 or 3 months later. RESULTS: Twelve of 50 neonates with neonatal seizures (24%) developed postneonatal epilepsy. Seventy-five percent (9 of 12) of the children with postneonatal epilepsy were eventually seizure-free without AED (antiepileptic drug), and 25% (3 of 12) had seizures at the last follow-up (modified angel classification 2 or 3, mean follow-up period; 52 months). On the univariate logistic regression analysis, abnormal EEG, Magnetic resonance imaging (MRI) findings, combined with encephalopathy and the number of AEDs were correlated with postneonatal epilepsy (P<0.05). On the multivariate analysis, the persistent abnormality on the follow-up EEG was correlated with postneonatal epilepsy (adjusted odds ratio=20.78; P=0.016). CONCLUSION: The number of intractable cases was relatively low, indicating good prognosis in postneonatal epilepsy. Abnormal EEG, MRI findings, combined with encephalopathy, and the number of AEDs were very good predictors of postneonatal epilepsy. The persistent abnormality in the follow-up EEG was more frequently seen in postneonatal epilepsy patients.
