This study was to examine the developmental dental abnormalities in childhood cancer survivors. Risk factors were assessed for 125 children with radiographic data through a retrospective analysis of medical records and panoramic images. 68.0% of childhood cancer survivors exhibited at least one dental abnormality. The types of abnormalities varied depending on the age at cancer diagnosis and treatment intensity, ranging from microdontia (43.2%), to abnormal root development (39.2%) and tooth agenesis (33.6%). Logistic regression analysis demonstrated that a young age at diagnosis (under 3 years), the use of heavy metal agents, a history of hematopoietic stem cell transplantation (HSCT), and combination treatment of chemotherapy, radiation therapy, and HSCT were associated with a significantly higher risk for overall dental abnormalities. The increased risk ratios were 6.00, 3.06, 3.22, and 7.87, respectively (p < 0.05). The results of this study will predict dental abnormality in permanent dentition according to the diagnosis age and treatment method of childhood cancer.

This study observed and investigated the commute time of dual-earner couples from a family developmental perspective. It tested whether the household responsibility hypothesis was effective in explaining the gender gap in the commute time for these couples. I extracted 2,103 time diaries written by 1,266 matched couples from the 2014 Korean Time Use Survey data for this study. The sample was categorized by the age of the eldest child into four age groups of 0-6, 7-12, 13-18, and 19-29. Analytic results from ANOVA, Scheffé test, and OLS regression are as follows. First, husbands traveled longer hours to work than wives in all age groups, while the commute time of couples tended to increase along with the child' age. However, couples in the child group aged 7 to 12 had the shortest commute time. Second, domestic labor time of wives were negatively associated with the commute time, which appeared to support the household responsibility hypothesis. Third, in the child group aged 7 to 12, wives spent more time for work commute as their income increased; however, wives with traditional gender role attitudes had a shorter commute time in the child group aged 0 to 6. Forth, neither the wives' nor husbands' work characteristics were related to the wives' commute time; however, both wives' and husbands' work characteristics were related to the husbands' commute time. The findings suggest the possibility of spatial entrapment by working wives throughout the family life cycle due to household responsibilities, which provides implications for policy intervention in consideration of the gender gap in commute time for dual-earner couples.

Purpose: This study aimed to identify and compare the risk factors of depression among middle-class Korean workers. Methods: A cross sectional study was designed for secondary data analysis. From the 8th Korean Medical Panel Survey (2008~2013), a total of 3,056 data was drawn and analyzed. With SPSS version 24, a developmental stage comparison, with the stage being young adults (20~39), middle-aged adults (40~64), and older adults (65+) were conducted. Frequency, percentage, 𝑥² test and logistic regression analysis were statistical tools used to analyze the data. Results: In all developmental groups, experience of frustration was found to be a common risk factor of depression. Stress from excessive task, peer-compared subjective health status, and self-perceived social class were risk factors of depression in the young adults and the middle-aged adults. Anxiety for the future significantly influenced depression in the middle-aged adults and older adults. Conclusion: Experience of frustration was a major risk factor of depression among Korean middle-class workers. Interventions to reduce depression need to be developed focusing on the specific risk factors by developmental stages such as experience of frustration, stress from task burden, poor peer-compared subjective health status and anxiety for the future.

An experiment was conducted to establish a large scale production method of anti-serum against chicken IgM and to profile the developmental changes of serum IgM levels during the feeding period(from hatching to 7 weeks of age) in broiler chicks. Blood samples were taken from Hubbard chicken at the age of hatching, three days of age, and weekly thereafter till to 7 weeks of age. The pure IgM was isolated from ammonium sulfate treated chicken serum by both sephadex G-200 and sepharose CL-6B chromatography. The breaking-through peak containing IgM appeared from the fraction 26 to 28. These fractions consisted mainly of IgM when tested by anti-chicken IgM(Nordic, Netherlands). Immunized with the heavy chain of this purified IgM, the rabbit immune sera(anti-chicken IgM) were formed a reaction only with the purified chicken IgM. The quantitative assay of serum IgM were carried by RID method. The optimal time for diffusion was 14 hours and the coefficient of determination($R^{2}$) for regression equation of standard curve was 0.992. It was observed that IgM concentrations were the highest at hatching(3.23 mg /mL), after that decreased gradually. From 2 to 5 weeks of age the levels unchanged(2.0 ~ 2.3mg /mL), and gradually decreased to 7 weeks of age(1.3 mg /mL).

Purpose: This study was done to determine whether a parenting education program using responsive teaching strategies is effective for parenting stress, maternal interactional behavior and behavioral problems in children at risk for Attention Deficit Hyperactivity Disorder (ADHD). Methods: Participants in this study were 17 elementary school children and their parents. The ADHD risk group was determined by scores on the Korean-ADHD Rating Scale. The parenting education program was developed based on Dr. Mahoney's responsive teaching curriculum. Mothers participated in the program once a week for 8 sessions. Treatment outcome was evaluated using the Korean version of the Child Behavior CheckList (K-CBCL), parenting stress, maternal interactional behavior, and child pivotal developmental behavior. Data were analyzed using Wilcoxon signed rank test, Mann-Whitney test, and regression analysis. Results: After the parenting education program, no significant difference in parenting stress (Z=-1.00, p=.320) was found, but there was a significant decrease in the child's internal behavior problems (Z=-2.05, p=.040), and also a significant improvement in maternal interactional behavior and a significant difference in child pivotal developmental behavior (Z=-2.67, p=.008). Conclusion: The results indicate that parenting education programs based on responsive teaching strategies are effective and that application of a program is recommended to prevent behavioral problems and improve maternal child interaction for children at risk for ADHD.

Background: This study examined the effect of having a usual source of care on the degree of patient-centered communication among persons with disability. The role of the usual source of care has been emphasized to improve patient experience, especially for patients with complex health conditions. Methods: This study used the 2017-2018 Korean Health Panel data, and the final study observations were 22,475 (20,806 people without disability and 1,669 people with disability). We applied generalized estimating equation model to show the effect of having a usual source of care on patient-centered communication, and subgroup analysis considering the types and severity of disabilities. Results: Persons who have disabilities, compared with ones without it, significantly had more usual sources of care (32.4% vs. 24.6%). By type of disability, persons with mental (51.4%), internal organ (43.8%), visual (37%), and physical disabilities (31.6%) had more usual sources of care than hearing/speech (26.6%), and developmental disabilities (18.6%). The average score of patient-centered communication was higher among who had a usual sources of care (3.2 vs. 2.7), and the regression analysis showed that having a usual sources of care was positively associated with higher patient-centered communication score (𝛽=0.476, p<0.05). However, the positive effects of usual sources of care was not observed among persons with severe hearing/speech, developmental, and mental disabilities. Conclusion: This study showed that role of patient-centered communication was limited in persons with severe hearing/speech disabilities, developmental, and mental disabilities. The education programs and supports are needed to improve communication skills between medical staff and persons with specific types of disabilities.

Pbjective : A significant proportion of children with autism spectrum disorders (ASD) have regression characterized by loss of previously acquired skills. The purpose of this study was to compare demographic, clinical characteristics and autism-related symptomatology of the children who have regression with children who don't have regression. Methods : The subjects with ASD and their unaffected siblings (SIB) were recruited from the Korean Autism Genetic Study Consortium. Typically developing children (TC) were volunteered from community. The subjects were administered the Korean version of Autism Diagnostic Interview-Revised (K-ADI-R) and the Korean version of Autism Diagnostic Observation Schedule (K-ADOS) to diagnose or exclude ASD. Regression was defined on the basis of K-ADI-R data. The Korean version of Vineland Adaptive Behavior Scale (K-VABS), Aberrant Behavior Checklist (K-ABC) and Social Responsiveness Scale (K-SRS) were obtained from their parents. Results : Regression occurred in 8.33% (n=14) of children with ASD (n=168). Any SIB (n=166) and TC (n=53) did not experience regression. Regression was associated with lower IQ and lower score of K-VABS. There was no difference in autism symptom severity and K-ABC, K-SRS scores, between children with ASD who experienced regression and who did not. Conclusion : Regression seems to be a distinctive feature of ASD. Regression is associated with cognitive and more general functions, rather than symptoms specific to autism.
