Background: The current pandemic has affected people's health multidimensionally. This study aims to investigate musculoskeletal pain, sleep quality, depression levels, and their relationships in individuals belonging to different age groups during COVID-19 in Turkey. Methods: A web-based self-administered survey that consisted of demographic questions, The Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI), and scores of musculoskeletal pain was sent to participants. Pearson correlation analysis was used for determining the statistical relationship between variables. Results: The study includes 1,778 participants. The highest percentage for mild, moderate, and severe pain was in the head (49.8%), back (15.5%), and head (11.5%), respectively. The PSQI-total had shown a weak correlation with pain levels in all body parts. The highest correlation for sleep quality and pain levels was between the PSQI-5 and lower back pain. There was a weak correlation between PSQI-2 and the BDI score, and a moderate correlation between the PSQI-1, PSQI-5, PSQI-7, PSQI-total, and BDI score. Pain in all body parts showed a weak correlation with depression level. Conclusions: This study showed that musculoskeletal pain was varied in body parts with different intensities according to age groups in Turkey during the pandemic. The most common pain was in the head, back, and lower back. Headache was found correlated with the parameters of sleep quality. Pain of the head, neck, back, lower back, and shoulder were correlated with sleep latency. Sleep quality was associated with depression and musculoskeletal pain, while musculoskeletal pain was correlated with depression.

The purpose of this research is to find relationships between safeguards' personality traits and stress coping behaviors. The findings then could provide data to adapt safeguards to their duties. For that, personality traits such as sociability, stability and stress coping behaviors and the effects were investigated. In addition, cognitive aspects which were known to influence stress coping behaviors were appraised. The findings of this research are as follows, First, regarding personality traits and stress coping behaviors, the unstable and unsocial group used the emotion-focused coping style more than the stable and social group. The two groups didn't show any significant differences in the problem-focused coping style. The A-type group used both the problem-focused style and the emotion-focused style more than the B-type group. The common characteristic of the unstable, the unsociable and the A-type groups was the heavy use of avoidance behaviors of the emotion-focused coping style. Second, In the correlation between the personal traits and the stress coping effects regarding adaptability, the stability influenced stress coping effects. Third, regarding the personality traits, the coping styles and the coping effects, A-type group showed high correlation with the sociability but not with the stability. The problem-focused coping style showed high correlation with the emotion-focused style. Fourth, the cognitive appraisal on the stress causes influenced the stress coping styles but not the stress coping effects. Fifth, the cognitive appraisal on the same stress causes didn't show any significant differences among the personality traits.

Relationships among ginsenosides, panaxadiol(PD), panaxatriol(PT), and total saponin(TS) in Panax ginseng root (2nd Year) grown with culture solotion different in nitrogen, phosphorus and potassium level were analyzed by simple correlation, multiple regression and standard partial regression coefficient. The closeness between ginsenosides by simple correlation was closely related with the similarity of molecular structure. The content of PT was much attributed to Re and Rg1. The contribution order of ginsenosides for PD was Rb1>Rb2$\geq$Rd>Rc. There was significant positive correlation between PT and PD but PD increased more rapidly than PT. Thus total saponin depended much on PD and PT/PD decreased with the increase of total saponin content. All ginsenosides, especially Re showed decreasing tendency with the increase of root weight.

The interrelationships between growth rates (and size) of the selected cranifacial dimensions and body dimensions (height and weight) were investigated in the longitudinal data of primary school children from 6 to 11 years of age. The data were obtained from serial cephalometric radiographs and health record which were taken at one year interval. Regression analyses were used to analyze the data. The main concludions might be summarized as follows; 1. Size relationships between body height (and weigh) and S-Gn, posterior facial height (s-Go), total mandibular length (Ar-Gn) showed high significant correlation, but no association between body height, weight and anterior cranial base length (S-N). 2. Correlation coefficients between facial dimensions and body height (and weight) were getting lower with age increase. 3. At all age groups, significant prediction equation for some facial dimensions with body height and weight were obtained. 4. In this sample, the growth rates of facial dimensions and body height and weight showed almostly constant during this age period and the growth rate of body height and weight of girls was exceeded that of boys. 5. A relatively high degree of variation between individuals existed in the sample. 6. A positive correlation was found for the relationship between the growth rates of facial dimensions and those of body height (and weight) in boys and girls, but was not found in total samples.

Purpose: This study was to identify the relationships of trait anger, mode of anger expression, and perceived stress to mental health status in middle aged women. Method: The subjects were 157 middle aged women from 40s to 60s who lived in Seoul. Data was collected by questionnaire surveys using the convenience sampling. The instruments used for this study were Spielberger's trait anger scale and anger expression scale, Cohen, Kamarck, and Mermelstein's perceived stress and Derogatis's SCL-90-R. The collected data was analyzed using descriptive statistics, Pearson correlation coefficient, and Stepwise multiple regression with SAS/PC. Result: The trait anger of middle aged women indicated a significantly positive correlation to perceived stress(r=.180, p=.023) and mental health status(r.=021, p=.014). Anger-in(r=.237, p<.05), and perceived stress(p=.461, p<.01) showed significantly positive correlation to mental health status. The most significant predictor influencing health status of middle aged women was perceived stress, and anger-in and the variance explained was 27%. Conclusion: These results suggested that middle aged women with high degree of trait anger is likely to be high in stress perception. Perceived stress and anger-in are major factors influencing mental health status.

Transcription factors regulate gene expression by binding to gene upstream region. Each transcription factor has the specific binding site in promoter region. So the analysis of gene upstream sequence is necessary for understanding regulatory mechanism of genes, under a plausible idea that assumption that DNA sequence motif profiles are closely related to gene expression behaviors of the corresponding genes. Here, we present an effective approach to the analysis of the relation between gene expression profiles and gene upstream sequences on the basis of kernel canonical correlation analysis (kernel CCA). Kernel CCA is a useful method for finding relationships underlying between two different data sets. In the application to a yeast cell cycle data set, it is shown that gene upstream sequence profile is closely related to gene expression patterns in terms of canonical correlation scores. By the further analysis of the contributing values or weights of sequence motifs in the construction of a pair of sequence motif profiles and expression profiles, we show that the proposed method can identify significant DNA sequence motifs involved with some specific gene expression patterns, including some well known motifs and those putative, in the process of the yeast cell cycle.
