Objectives: The Short Form 36 (SF-36) questionnaire is increasingly being used to measure health-related quality of life (HRQoL) in Indonesia. However, evidence that it is valid for use in Indonesian adults is lacking. This study assessed the validity and reliability of the SF-36 in Indonesian middle-aged and older adults. Methods: Adults aged 46-81 years (n=206) in Yogyakarta, Indonesia completed the SF-36, another measure of HRQoL (the EuroQoL visual analogue scale [EQ-VAS]), and measures assessing their demographic characteristics. Fifty-four percent (n=121) completed the SF-36 measure again 1 week later. Confirmatory factor analysis was conducted to confirm the factor structure of the SF-36. Internal consistency reliability was estimated using Cronbach's alpha, and test-retest reliability was assessed using intraclass correlations. Convergent and discriminant validity were assessed by computing correlations among SF-36 subscales, between subscales and the 2 component scores, and between component scores and EQ-VAS scores. Results: Most scaling assumptions were met. The hypothetical factor structure fit the data poorly (root mean square error of approximation [RMSEA]=0.108) and modification was required for a good fit (RMSEA=0.060). Scores on all subscales demonstrated acceptable internal consistency (α>0.70) and test-retest reliability (r>0.70). Divergent validity was supported by weak to moderate interscale correlations (r=0.19 to 0.64). As expected, the 2 summary scores were moderately to strongly correlated with the EQ-VAS (r>0.60). Conclusions: The findings adequately support the use of SF-36 in Indonesian middle-aged and older adults, although the optimal algorithm for computing component scores in Indonesia warrants further investigation.

대학생이 진로결정을 하는 것은 대학생활을 적응하면서 다양한 경험으로 인해 졸업 후 자신의 진로에 관한 생각이 입학 당시의 생각과 달라질 수도 있다. 경호 전공생의 경우 경호라는 전문성을 가지고 있는 분야이기 때문에 졸업 후에도 경호 분야로 진로를 결정할 것이라는 생각을 하게 된다. 그러나 대학에서 자신의 전공 분야로 졸업 후 취업으로까지 이어지는 경우는 생각보다 많지 않으며, 가족이나 친척 등 주변 환경에 의해 결정되는 경우가 많다. 이 연구는 대학생활 적응과 진로결정에 관련된 선행연구를 기초로 하여 경호를 전공하고 있는 학생들의 대학생활 적응 및 진로결정의 연구모형을 설정한 다음 이를 규명하고자 한다. 즉, 이 연구에서는 사회인구학적 특성에 다른 대학생활 적응 및 진로결정의 차이를 분석하고, 대학생활 적응이 진로결정에 미치는 영향을 분석하는 것이 주된 목적이다. 본 연구에서는 다음과 같은 결론을 도출하였다. 첫째, 사회인구학적 특성에 따른 대학생활 적응은 차이가 있다. 즉, 성별에 따른 정서적 적응은 남성이 높다. 학년 및 연령에 따른 정서적 적응은 학년 및 연령이 증가할수록 높다. 둘째, 사회인구학적 특성에 따른 진로결정은 차이가 있다. 즉, 학년에 따른 진로결정 보류는 1학년이 높으며, 연령에 따른 진로결정 회의감은 1학년이 높다. 셋째, 대학생활 적응은 진로결정에 영향을 미친다. 즉, 환경적 적응이 높을수록 진로결정 보류, 진로결정 회의감이 낮고 진로결정 편안함은 높다. 정서적 적응이 높을수록 진로결정 회의감이 낮다. 대인적 적응이 높을수록 진로결정 편안함이 높다.

Purpose: This study was conducted to evaluate the construct validity, reliability, measurement invariance, and latent mean differences in the Breastfeeding Adaptation Scale-Short Form (BFAS-SF) for use with mothers at 2 weeks postpartum. Methods: This methodological study was designed to evaluate the validity, reliability, and measurement invariance of the BFAS-SF at 2 weeks postpartum, with data collected from 431 breastfeeding mothers. Confirmatory factor analysis and multi-group confirmatory factor analysis were conducted to assess the factor structure and the measurement invariance across employment status, delivery mode, parity, and previous breastfeeding experience, and the latent mean differences were then examined. Results: The goodness of fit of the six-factor model at 2 weeks postpartum was acceptable. Multi-group confirmatory factor analysis supported strict invariance of the BFAS-SF across employment status and delivery mode. Full configural invariance, full metric invariance, and partial scalar invariance across parity and full configural invariance and full metric invariance across previous breastfeeding experience were supported, respectively. The results for latent mean differences suggested that mothers who were employed showed significantly higher scores for breastfeeding confidence. Mothers who had a vaginal delivery showed significantly higher scores for sufficient breast milk and baby's feeding capability. Multiparous mothers showed significantly higher scores for baby's feeding capability and baby's satisfaction with breastfeeding. Conclusion: The validity and reliability of the BFAS-SF at 2 weeks postpartum are acceptable. It can be used to compare mean scores of breastfeeding adaptation according to employment status, delivery mode, and parity.

This study was carried out to evaluate health effects of aircraft noise using THI(Todai Health Index). The questionnaire survey was conducted around the Gimpo International Airport in Seoul, Korea from 8 August to 9 September. Study subjects, 614 residents, were divided into three groups following to the aircraft noise level: under 75WECPNL(area(1)), $75{\sim}80$WECPNL(area(2)) and $80{\sim}85$WECPNL(area (3)). Twelve scale scores are converted to dichotomous variables based on scale scores of 90 percentile value or 10 percentile value in the control group. Logistic regression analysis taking twelve scores converted as the dependent variables and WECPNL(area), age, gender as the independent variables is conducted. Significant dose-response relationships are found in the scale of MOUT, DEPR, NERV, LIFE, where p denotes significance probability of trend test. Factor analysis was carried out and 2 factors are extracted which may be called "somatic factor" and "mental factor". The dose-response relationship with these factors and noise exposure is not clear. But strangely the odds ratio of mental factor in area 2 is the highest and the annoyance of this area is also higher than other areas.

The purpose of this study was to analyze science gifted students' creativity subscales. The Torrance Tests of Creativity Thinking(TTCT) were administered to 385 science gifted students from 2006 to 2010 for this study. The results were as follows: First, fluency correlated highly with originality, and elaboration also highly correlated with abstractness of titles. All of the correlation coefficients of the variables with resistance to premature closure were high. Second, the elaboration scores were higher than other variables, and abstractness of titles scores and resistance to premature closure scores were lower than other variables regardless of regions and gender. There was no significant difference according to regions, but the elaboration scores of female science gifted students were significantly higher than male science gifted students'. The fluency scores were the most influential factor to the creativity index among the creativity subscale scores. Third, after completing the science gifted program, students showed significant difference in fluency scores, abstractness of titles scores, and resistance to premature closure scores; however, they showed no difference in originality scores and elaboration scores.

Objective : The aim of this study was to find associations between specific symptoms and suicidal behavior by using global severity on depression scales. Methods : Data were obtained from 1,183 patients of CRESCEND study. Factor analysis of the 17-item Hamilton Rating Scale for Depression (HAM-D) and the Beck Depression Inventory-II (BDI-II) was used to compare symptom clusters between the past suicide attempters and the non-suicide attempters, among the patients with depressive disorders. Results : Factor analyses of HAM-D and BDI-II extracted three factors. Suicide attempters had significantly higher scores on core factor of HAM-D, including depressed mood, feeling of guilt, suicide, work, and activities. The higher scores on all factors of BDI-II or scores correlated with a total of 7 suicide attempts and with known risk factors for suicidal behavior. Conclusion : These findings suggest that the suicide attempters complained of more cognitive, affective, somatic symptoms on BDI-II, but the core factor on HAM-D was the only differentiated factor between the two groups. Clinician-rated scales as well as self-reported questionnaires were valid in measuring suicidal attempts, and the clinical profile may help in guiding the studies of biological correlates and the treatments to reduce suicide risk.

This study was aimed to provide the measurement data and shape classification of the head of the Korean male children for the headwear sizing systems. Five hundred twenty male children, aged nine to twelve years, participated f3r this study. The 17 regions on the head and height, weight of the subjects were directly measured by the expert experimenters. Factor analysis, cluster analysis, GLM analysis and Tukey HSD test were performed using these data. Through factor analysis, low factors were extracted upon factor scores and those factors comprised $69.76\%$ for the total variances. Three clusters as their head shape were categorized using four factor scores by cluster analysis. Type 1 was characterized by the widest width and Bitragion arc, shortest head length. Type 2 had the longest head length and the widest side width and the highest head length and head circumference. Type 3 was characterized by the smallest head circumstance, head width and side width, and medium head length.

The purpose of this study was to evaluate quality characteristics of the bread added with chlorella growth factor(CGF). The bread was manufactured by adding 0.5%, 1.0%, 1.5% or 2.0% of CGF(w/w) to wheat flour. The bread volume was increased from 1,755mL to 1,840mL as CGF contents increased from 0% to 1.0%. The lightness(L values)and the redness(a values) decreased with increasing CGF contents, but the yellowness(b values) increased with increasing CGF contents. Textural characteristics of the bread were influenced by adding the CGF. The breads containing CGF showed a decrease in hardness, springiness, gumminess and chewiness. In sensory evaluation, sensory scores decreased with increasing CGF contents for color. On the other hand, the highest sensory scores for grain, flavor, taste, softness, chewiness, aftertaste and overall acceptability were obtained, when CGF content was 1.0%. In conclusion, the bread with 1.0% CGF was the best quality in textural and sensory evaluation.
