DNA profiles have been increasingly used as the most reliable means to identify remains from war or mass disaster. To establish the identity with such a large set of victims, special care should be taken to correlate remains with correct family references while avoiding coincidental match between non-relatives. Therefore we address here relevant statistical and combinatorial issues in the DNA identification of mass victims. A simple and general formula for the likelihood ratio governing any potential kinship between two DNA profiles was presented, and for that purpose, the probabilities that a given relative and an individual share autosomal identical-bydescent alleles were calculated. In addition, a method dealing with the allele drop-out in kinship analysis and the estimation of a cold hit were discussed.

Background:
Diet and physical activity are key factors related to depressive mood. Previous studies have demonstrated the effects of diet and physical activity on depression. However, the effect of energy intake-expenditure balance (EIEB) on mental health has not been fully evaluated. This study aimed to analyze the association between EIEB and depression.
Methods:
A total of 13,460 participants (5,660 men and 7,800 women) aged ≥19 years were obtained from the 2014, 2016, and 2018 Korea National Health and Nutrition Examination Survey (KNHANES). EIEB was defined as the difference between the daily energy intake and energy expenditure. Energy intake was calculated and provided by the KNHANES using a 24-hour recall survey. Energy expenditure was estimated as the sum of basal metabolic rate and physical activity. Logistic regression analyses were used to investigate the association between sex-specific quartile groups (Q1–Q4) of EIEB and depression after adjusting for socioeconomic status, body mass index, lifestyle factors, and underlying diseases.
Results:
Women in Q3 of EIEB (211–669 kcal) had a significantly lower risk of depression (odd ratio [OR], 0.78; 95% confidence interval [CI], 0.67–0.92) than those in Q1 of EIEB (<-167 kcal). The adjusted ORs of depression were 0.87 (95% CI, 0.75–1.02) in Q2 and 0.86 (95% CI, 0.74–1.01) in Q4, with P for trend=0.030. There were no significant associations between the EIEB quartile groups and depression in men after adjusting for potential confounders (P for trend=0.564).
Conclusion
Our results suggested that the EIEB is negatively associated with depression in Korean women.

PURPOSE: This descriptive study was done to identify the academic achievement, self-directed learning (SDL), and critical thinking disposition (CTD) of nursing students according to their learning styles. METHOD: The participants were 240 nursing students. Data were collected using structured questionnaires which included Kolb's Learning Style Inventory, Academic Achievement in Fundamental Nursing and Health Assessment, Self Directed Learning Readiness Scale, and California Critical Thinking Disposition Inventory. Data were analyzed using chi2 test, ANOVA, Pearson' correlation coefficients, and Spearman rank correlation coefficient. RESULTS: One third of respondents were shown to be Convergers in their learning style (33.3%). The Academic Achievement of students who were Convergers was significantly higher than those who were Divergers or Accommodators (F=5.95, p=.001). The SDL and CTD of students who were Convergers were significantly higher than Divergers and Assimilators (F=9.67, p<.001 and F=8.42, p<.001). No significant correlations were found between Academic Achievement and SDL or CTD, but a statistically significant positive correlation was found between SDL and CTD (r=.68, p<.001). CONCLUSION: The findings of this study indicate that learning style influences academic achievement, SDL and CTD.

There have been several attempts for criminal DNA profiling in Korea, but ended without any fruitful results. Recently new movement for the profiling has just been started. Many have to be solved in advance, which can be divided largely into two, technical aspects and legal system which could support the application. To build up profiling for any purpose, work for the standardization must be driven, because many are involved in the work. Authors have checked the status of the DNA typing in Korea and have reviewed its quality by statistical approach. All the popular forensic journals, Korean or international covering from 1997 to 2004, were reviewed to check whether it contains articles on Korean. All the articles containing genetic data on Korean were selected and their results were compared statistically. Total 67 articles were chosen. Articles were on 116 loci, among which 54 were autosomal, 32 were Y chromosomal and the remaining were X chromosomal. Among 32 Y chromosomal loci, 11 were bi-allelic. For the 50 loci two or more lab reported separately. For these loci the results from different lab were compared. There was no statistically significant difference for most of the loci, but some of the loci, especially on Y chromosomal STR loci, showed some differences. Data were showed with some review.

Although atopic dermatitis (AD) is known to be a representative skin disorder, it also affects the systemic immune response. In a recent study, myoblasts were shown to be involved in the immune regulation, but the roles of muscle cells in AD are poorly understood. We aimed to identify the relationship between mitochondria and atopy by genome-wide analysis of skeletal muscles in mice. We induced AD-like symptoms using house dust mite (HDM) extract in NC/Nga mice. The transcriptional profiles of the untreated group and HDM-induced AD-like group were analyzed and compared using microarray, differentially expressed gene and functional pathway analyses, and protein interaction network construction. Our microarray analysis demonstrated that immune response-, calcium handling-, and mitochondrial metabolism-related genes were differentially expressed. In the Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology pathway analyses, immune response pathways involved in cytokine interaction, nuclear factor-kappa B, and T-cell receptor signaling, calcium handling pathways, and mitochondria metabolism pathways involved in the citrate cycle were significantly upregulated. In protein interaction network analysis, chemokine family-, muscle contraction process-, and immune response-related genes were identified as hub genes with many interactions. In addition, mitochondrial pathways involved in calcium signaling, cardiac muscle contraction, tricarboxylic acid cycle, oxidation-reduction process, and calcium-mediated signaling were significantly stimulated in KEGG and Gene Ontology analyses. Our results provide a comprehensive understanding of the genome-wide transcriptional changes of HDM-induced AD-like symptoms and the indicated genes that could be used as AD clinical biomarkers.
