The aim of this study was to develop and validate an instrument to measure the separation anxiety of mothers who use child care facilities. The scale was developed as follows: initial items generated, validity and reliability tests performed, and final items extracted. The initial items were developed through a literature review and interviews. The content validity was verified by five experts. Using a final questionnaire, the data was collected from 204 mothers who used child care facilities with a convenient sampling method. The construct validity was evaluated by item analysis, exploratory factor analysis and confirmatory factor analysis. The results of confirmatory and exploratory factor analyses showed that the separation anxiety consisted of 6 factors: the mother's guilty feelings (5-items), safety of child care facilities (5-items), trust of teachers (5-items), child's anxiety (4-items), interaction anxiety with the child (4-items), and management of child care facilities (3-items). The separation anxiety scale for mothers using child care facilities consisted of 26 items. The reliability of the developed scale was examined. The Cronbach's ${\alpha}$ coefficient was 0.93. These results show that this scale is a valid and reliable instrument for measuring the separation anxiety level of mothers who use child care facilities.

This study's aim is to examine child's life competency that middle high school parents perceive and study the influence of parenting stress, parent efficacy, depression, parent education participation on child's life competency. The study was conducted towards parents who have children attending middle school and high school in Dae-jeon. Official cooperation documents were sent to middle schools and high schools located in Dae-jeon in April, 2013. Surveys were sent by e-mail and a total of 800 replies (excluding those with missing data) collected throughout December 10th to 20th, 2013 were used in the final data analysis. SPSS 23.0 and AMOS 23.0 programs were used for analysis and subject's general characteristics and percentage were analyzed. Pearson's product moment correlation coefficient was used in order to examine the variant's relation. Path model analysis was used to study variant's path and direct and indirect effects of the paths were analyzed as well as the significance. The study's results showed that child life competency and related variants had a high correlation and path model analysis showed that parenting stress, parent efficacy, depression, participation of parent education had a direct and indirect influence on child's life competency. Parenting stress has influence on parent efficacy and depression, but parent education has a different influence on child's life efficacy according to participation. Based on these results, policy suggestions are made throughout family academic perspectives in order to enhance child's life competency.

The purpose of this study is to identify the level of father-child attachment and to explore possible factors that may influence such attachment level in marital satisfaction, marital conflict, parenting stress, and parenting attitudes. The data were collected using a structured questionnaire from 131 fathers living in B city, between February 16 and August 16 in 2014. The collected data were analyzed using descriptive statics, ANOVA, Pearson correlation coefficient, and multiple regression with SPSS 21.0 program. The mean of father-child's attachment was $3.79{\pm}0.47$. The level of father-child attachment was different according to monthly income (f=5.25, p<.010). There was a significantly positive correlation between father-child attachment and father's marital satisfaction (r=.28, p=.001). Father-child attachment was negatively correlated with father's marital conflict (r=-.23, p=.01), parenting stress (r=-.44, p<.001), acceptance-rejection (r=-.64, p<.001), and control (r=-.30, p<.001), with statistical significance. The acceptance-rejection attitude of father had significant effects on father-child attachment and accounted for 40% of the total variance of the attachment. These results indicated that decreasing the father's acceptance-rejection attitude could be effective in improving father-child attachment.

Although Attention Deficit Hyperactivity Disorder(ADHD) has been considered as the disorder occurring during childhood, the prevalence is increasing among adolescents and adults. The prevalence rate varies from 2.0 to 14.3% due to the difference of diagnostic criteria, different assessment methods, or subjects' age difference. Therefore, it needs to make age specific(i.e., for children, for adolescents, and for adults) assessment tools. Authors translated Conners-Wells Adolescents Self-Report Scales(short form)[CASS(S)] in to Korean to get validity and reliability as a way of development of assessment tool for adolescent with ADHD in Korea. CASS(S) was translated and corrtected by three psychiatrists and one clinical psychologist. To examine the concurrent validity and test-retest validity, CASS(S) was applied with K-YSR on one class of each grade in a middle school in Seoul with two week interval(total 115：male 58, female 57). To test validity, authors analysed and got Cronbach's as internal consistency. Construct validity was done by principal axis factor analysis on 4,354 students. As a result, Cronbach's alpha for internal consistency was .88, Pearson coefficient for test-retest reliability .83, and coefficient for concurrent validity .65. And in the factor analysis to examine construct validity, three factors were revealed as cognition, hyperactivity, and conduct. These results shows that CASS(S) may be useful tool for adolescents with ADHD, although there was a limit not to be done the comparison with clinical groups.

Objectives : The definition of a hidden youth is a young person who has completely withdrawn from society and shut himself or herself away for more than 3 months. Those pathologically-withdrawn youths have become a burden not only to society but also to the family. However, screening of these hidden youths cannot be done easily. This study focused on developing a primary effective screening tool for these hidden youths. Methods : The 42 participants of this study were parents of hidden youths that are between 8 to 25 years old. They were selected from from mental health centers and psychiatric clinics around Seoul and Gyeonggi Province. We also recruited 239 parents of middle and high school students in the Seoul metropolitan area for a control group. In order to decide the concurrent validity of this questionnaire, we used the Symptom Checklist-90-Revision, Children's Depression Inventory, Beck Depression Inven-tory, Social Anxiety Scale for Children-Revised, Social Anxiety and Distress Scale, Avoidant Personality Disorder Scale, and State-Trait Anxiety Inventory for Children. SPSS version 12.0 was used for statistical analysis. Results : Cronbach's alpha values, the reliability coefficient to represent internal consistency, were between 0.396 and 0.935, which showed relatively high internal consistency for this questionnaire. The test-retest coefficient was between 0.68 and 0.78, which was a statistically significant result. In a factor analysis, 4 factors such as avoidance, withdrawal, isolation, and apathy were extracted. In a concurrent validity test with SCL-90-R, the isolation factor showed a statistically-significant relationship with a phobic-anxiety sub-scale, and avoidance and withdrawal sub-scales were remarkably correlated with the interpersonal sensitivity sub-scale. Conclusion : Since the questionnaire for socially withdrawn youths has achieved statistically-satisfactory reliability and validity, it will be a useful method to screen for hidden youths in educational, community, and clinical settings.

This study examined the relations between home-environment, mother´s vacational environment, vocational sense and the career maturity of their child in girls high school. Also the study tried to help the children find the proper vocation and to guide them in school. The subjects of this were 514 couples of mothers and their children in girl´s school (2nd grade) living in In-cheon. Statistics used for data analysis are Frequency, Percentage, One-way ANOVA, DMR(Ducn´s Multiple Range Test), T-test and Pearson´s correlation coefficient. The main results were as follows: 1. To think of the career maturity of child in home-environment variable, it differed significant-ly by mother´s standard of education and father´s vocation. 2. According to the mother´s vocational environment variablees, career maturity of child differed significantly by work-state the degree of vocational satisfication. 3. To think of the general tendency of mother´s view of vocation the attitude of choosing vocaion is independent whether mother has work or not. The attitude of work and sex-role is openhearted whether mother has work or not. The attitude of work-value is more important in the case of mother´s having work. The attitude of work-respect is formal in both case. In general whether mother has work or not there´s no difference in the mother´s vocational sense. 4. The corelations between the mother´s vocational sense and career maturity differed significantly by the attitude of chdoosing vocation. 5. The career maturity of high school student differed significantly whether they are commercial high school student or academic high school student. Based on the findings it is recommended the mother´s age the standard of education the degree of vocational satisfication and the view of vocation are more influenced on the child´s career maturity than the mother´s work itself.

Background: In recent events of the coronavirus disease 2019 (COVID-19) pandemic, computed tomography (CT) scans are being globally used as a complement to the reverse-transcription polymerase chain reaction (RT-PCR) tests. It will be important to be aware of major organ dose levels, which are more relevant quantity to derive potential long-term adverse effect, for Korean pediatric and adult patients undergoing CT for COVID-19. Materials and Methods: We calculated organ dose conversion coefficients for Korean pediatric and adult CT patients directly from Korean pediatric and adult computational phantoms combined with Monte Carlo radiation transport techniques. We then estimated major organ doses delivered to the Korean child and adult patients undergoing CT for COVID-19 combining the dose conversion coefficients and the international survey data. We also compared our Korean dose conversion coefficients with those from Caucasian reference pediatric and adult phantoms. Results and Discussion: Based on the dose conversion coefficients we established in this study and the international survey data of COVID-19-related CT scans, we found that Korean 7-year-old child and adult males may receive about 4-32 mGy and 3-21 mGy of lung dose, respectively. We learned that the lung dose conversion coefficient for the Korean child phantom was up to 1.5-fold greater than that for the Korean adult phantom. We also found no substantial difference in dose conversion coefficients between Korean and Caucasian phantoms. Conclusion: We estimated radiation dose delivered to the Korean child and adult phantoms undergoing COVID-19-related CT examinations. The dose conversion coefficients derived for different CT scan types can be also used universally for other dosimetry studies concerning Korean CT scans. We also confirmed that the Caucasian-based CT organ dose calculation tools may be used for the Korean population with reasonable accuracy.

Purpose: To evaluate the association between elevated S100B levels with brain tissue damage seen in abnormalities of head magnetic resonance imaging (MRI; diffusion tensor imaging [DTI] sequence) in patients with status epilepticus (SE). Methods: An analytical observational study was conducted in children hospitalized at Dr Soetomo Hospital, Surabaya, from July to December 2016. The patients were divided into 2 groups: SE included all children with a history of SE; control included all children with febrile seizure. Blood samples of patients were drawn within 24 hours after admission. SE patients also underwent cranial MRI with additional DTI sequencing. The Mann-Whitney test and Spearman test were used for statistical analysis. Results: Fifty-three patients were enrolled the study. In the 24 children with SE who met the inclusion criteria, serum S100B and cranial MRI findings were assessed. Twenty-two children admitted with febrile seizures became the control group. Most patients were male (66.7%); the mean age was 35.8 months (standard deviation, 31.09). Mean S100B values of the SE group ($3.430{\pm}0.141{\mu}g/L$) and the control group ($2.998{\pm}0.572{\mu}g/L$) were significantly different (P<0.05). A significant difference was noted among each level of encephalopathy based on the cranial MRI results with serum S100B levels and the correlation was strongly positive with a coefficient value of 0.758 (P<0.001). Conclusion: In SE patients, there is an increase of serum S100B levels within 24 hours after seizure, which has a strong positive correlation with brain damage seen in head MRI and DTI.

This study investigated the effect of pre service teacher's empathic ability on teaching ethics, and child abuse report intention. The subjects were 168 pre-service teachers attending a university located in a micropolitan city. Questionnaires, which required self-reporting by pre service teacher, were used to investigate teacher's empathic ability, teaching ethics and child abuse report intention. The collected data were analyzed by frequency, percent, Pearson's correlation coefficient analysis and stepwise-regression analysis. From the major study findings, first, pre-service teacher's empathic ability was positively correlated with teaching ethics and child abuse report intention. Pre-service teacher's "take perspective", "imagine" of the cognitive empathic ability's subfactor was positively correlated with teaching ethics. Especially, empathic interest was positively correlated with teaching ethics. Cognitive empathy ability showed the highest relationship with ethics for early child. Emotional empathy showed the highest relationship with ethics in society. Second, the pre-service teacher's teaching ethics were influenced by taking perspective, imagining, and empathic attention. These results demonstrate the need to incorporate perspectives in the development of programs to promote pre - service early childhood teacher ethics and child abuse reporting.

The purpose of this study was to develop an instrument to measure family resilience for Korean families with a chronically ill child, and to test the validity and reliability of the instrument. Method: The items of instruments used based on the researchers' previous study of concept analysis of Korean family resilience. Nineteen item scales were developed with five domains. In order to test reliability and validity of the scale, data were collected from 231 families, who had a child with a chronic illness. Data was collected between August and September of 2001 in a 3rd level University Hospital in Seoul, Korea. Result: The results were as follows: As a result of the item analysis, 19 items were selected from the total of 37 items, excluding items with low correlation with the total scale. Five factors were evolved by factor analysis, which explained 56.4% of the total variance. The first factor 'Family strength' explained 28.5%, 2nd factor 'Family maturity' 8.7%, 3rd factor 'The ability to use of external resources' 7.0%, 4th factor 'Control' 6.6%, 5th factor 'The driving force for finance' 5.7%. The attributes in these factors were different with those identified by concept analysis of the family resilience in Korean families from the previous study. Cronbach's $\alpha$ coefficient of this scale was .8039 and Guttman spilt- half coefficient was .8184. Conclusion: The study support the reliability and validity of the scale. Because the main concept of family resilience was family strength, there were distinct differences in dimensions of family functioning scales.
