This study was undertaken to investigate the distribution of the chewing side preference and variations in the maximum bite force and facial morphology according to chewing side preference since unilateral chewing may cause morphologic and functional anomalies. 50 dental students who had no signs or symptoms of masticatory system and Angle's Class I relationship in posterior segments were selected, and divided into two groups, that is, 25 in bilateral chewing group(19 male and 6 female) and 25 in unilateral chewing group(10 male and 15 female). Maximum bite force was estimated and posteroanterior cephalogram were measured and statistically analyzed. The results were as follows: 1. There were more students with bilateral chewing side preference(68%) and unilateral chewing side group consisted of right side preference(68%) and left side preference(32%). 2. There was no significant difference in the strength of max. bite force between the right and left side in bilateral chewing group. The bite force of the chewing side was greater in the unilateral chewing group but less in the non-chewing side compared to those of bilateral chewing group with no significant difference. Max. bite force of chewing side was greater than that of non-chewing side in the unilateral chewing group(Female : p<0.05). Max. bite force of males was about twice in that of females in both groups(p<0.05). Max. bite force of chewing side of the unilateral chewing group was similar to that of the bilateral chewing group, but that of non-chewing side was less than that of the bilateral chewing group. 3. In comparison of the facial morphology, there was no statistically significant difference in the size between the right and left side of the bilateral chewing group and between chewing and non-chewing side of the unilateral chewing group.

Purpose: This study was conducted to identify the factors influencing sleep among Korea adolescents. Methods: This was a secondary data analysis of the 7th-8th National Health and Nutrition Survey 2016-2020. Participants were 1,984 people age 12-18. Data were analyzed using frequency, percentage, χ 2 test, and complex sample multiple logistic regression analysis. Results: The risk of sleeping more than 10 hours was 2.50 times higher in normal subjects, than subjects underweight in body weight perception (95% CI = 1.29-4.81). The risk of sleeping more than 10 hours was 2.10 times higher in overweight subjects, than subjects underweight in body weight perception (95% CI = 1.14-3.87). The risk of sleeping less than 8 hours was 1.36 times higher in subjects high in stress status, than subjects low in stress status (95% CI = 1.05-1.75). The risk of sleeping more than 10 hours was 1.99 times higher in subjects who had not eaten, than subjects who had been eating breakfast (95% CI = 1.11-3.55). Conclusion Thus, it is necessary to intensify sleep management required through proper health behavior as well as the mental health management of adolescents and improvement in eating behavior.

Purpose: The purpose of this study was to examine the effects of a mobile application on quality of life, wellness, and preventive behaviors against dementia among older adults who use senior citizen centers. Methods: Seventy-two older adults who used senior citizen centers were allocated to an intervention group (n=36) and a control group (n=36). The experimental treatment involved a cognitive enhancement program for preventing dementia using a mobile application for 12 sessions over 6 weeks. Data were analyzed using the t-test, chi-square test, Fisher’s exact test, paired t-test, and independent t-test. Results: The cognitive enhancement program based on a mobile application was effective for wellness (t = -3.87, p < .001) and preventive behaviors against dementia (t = -3.98, p < .001) for older adults who used a senior center. Conclusion The mobile application-based cognitive enhancement program developed in this study is recommended as an effective intervention for dementia prevention in older adults.

PURPOSE: To report the results of 134 cases in which add-on stereotactic core biopsy (ASCB) was performed in patients with mammographically detected breast lesions, and to evaluate the usefulness of this procedure. MATERIALS AND METHODS: We analyzed the results of ASCB of 134 breast lesions in 125 patients, performed during a 41-month period. The mammographic findings were suspicious malignant lesion in 38 cases, benign lesion in 18, and indeterminate lesion in 78. Surgical excision was performed in 23 cases, and follow-up mammography in 39. We analyzed the pathologic results according to each mammographic finding and correlated the results of core biopsy with those of surgical excision. We also evaluated the mammographic changes seen during follow-up, and associated complications and procedural difficulties. RESULTS: Samples were adequate for pathologic diagnosis in 95% of cases (127/134). ASCB revealed malignancy in 47% of cases (18/38) in which this was suspected on the basis of mammographic findings, and in 5% of cases (4/78) in which these findings were indeterminate. The pathologic results of core biopsy and of surgical excision agreed in 78% of cases (18/23). In two of five false-negative cases, ASCB revealed the presence of atypical ductal hyperplasia. The mammographic findings in these five cases were suspicious malignancy in three, and indeterminate in two. Specimen radiography showed calcifications in four cases. The size or extent of mammographic lesions did not change during the mean follow-up period of 17.3 months. In 13/125 patients (10%), the complications and procedural difficulties noted included arterial bleeding, dizziness, syncope, patient movement, and instrument failure. CONCLUSION: ASCB is accurate, safe and useful, but surgical excision should be considered when the ASCB result is either atypical ductal hyperplasia or benign but with mammographic diagnosis of suspicious malignant or indeterminate lesions.

OBJECTIVE: To evaluate the clinical usefulness of ICF (International Classification of Functioning, Disability and Health) through correlation among existing functional evaluation tools and examined environmental factors affecting its function. METHOD: One hundred eight persons with disabilities living in Seoul were randomly selected according to disability severity categories. Functional Independence Measure (FIM), modified Barthel index (MBI) and ICF were examined and subjects were interviewed by trained rehabilitation doctors and occupational therapists. We compared correlation between these three functional measurements. We coded environmental factors affecting function. That was used in second level of 74 ICF items. RESULTS: The average of FIM, modified Barthel index, capacity and performance scores of ICF was 112.76, 92.97, 5.74 and 3.19. There was a statistical correlation among FIM, Barthel index, and ICF. The facilitator chapters among ICF's environmental factors were support and relationships (51.9%), attitudes (45.8%) in order. Most facilitated second level domains among the 68 items were immediate family (66.77%) and health professionals (52.8%). The most barrier chapters in ICF were product and a technology (19.5%), environment changes (15.5%) in order. Most barrier second level domains were design, construction and technology of buildings for public use (37%) and assets (37.0%). CONCLUSION: ICF correlates with the existing functional evaluation tool and can facilitate management of activity and participation by linking the result with the environmental factors, which may exacerbate or minimize them

OBJECTIVES: Autism is a complex neurodevelopmental spectrum disorder with a strong genetic component. Previous neurochemical and genetic studies have suggested the possible involvement of the serotonin system in autism. Tryptophan 2,3-dioxygenase(TDO2) is the rate-limiting enzyme in the catabolism of tryptophan, which is the precursor of serotonin synthesis. The aim of this study was to investigate the association between the TDO2 gene and autism spectrum disorders(ASD) in a Korean population. METHODS: The patients were diagnosed with ASD on the basis of the DSM-IV diagnostic classification outlined in the Korean version of the Autism Diagnostic Interview-Revised and Autism Diagnostic Observation Schedule. The present study included the detection of four single nucleotide polymorphisms(SNPs) in the TDO2 gene(rs2292536, rs6856558, rs6830072, rs6830800) and the family-based association analysis of the single nucleotide polymorphisms in Korean ASD trios using a transmission disequilibrium test(TDT) and haplotype analysis. The family trios of 136 probands were included in analysis. 87.5% were male and 86.0% were diagnosed with autism. The mean age of the probands was 78.5+/-35.8 months(range: 26-264 months). RESULTS: Two SNPs showed no polymorphism, and there was no significant difference in transmission in the other two SNPs. We also could not find any significant transmission in the haplotype analysis(p>.05). CONCLUSION: We could not find any significant statistical association between the transmission of SNPs in the TDO2 gene and ASD in a Korean population. This result may not support the possible involvement of the TDO2 gene in the development of ASD, and further exploration might be needed to investigate other plausible SNP sites.
