Objective: Pain following the insertion of separators and archwires varies with age, sex, race, ethnicity, threshold, and health status. This study aimed to evaluate the characteristics of pain in orthodontic patients after the insertion of elastomeric separators, its effects on daily life, and its association with age and sex in a population not previously studied in this regard. Methods: A cross-sectional study of 130 patients undergoing orthodontic treatment included collecting data on demographics, pain experienced following the placement of separators, time of onset, duration, characteristics, change in dietary pattern or chewing side, intake of analgesics, and severity of pain on the Wong Baker's scale. The results are reported as counts and percentages. Associations between sex and age were evaluated using Pearson's chi-square test. Results: Among the 130 patients, 56.2% were 9-20 years old, 63.8% experienced pain following the insertion of separators, 22.9% had their first episode of pain at 4 hours, 56.6% experienced intermittent pain, and 37.3% experienced discomfort; 18.1% males and 81.9% females experienced pain following the insertion of separators. Pearson's chi-square test showed a significant association between pain and sex (P = 0.04). Most patients (37.3%) reported "hurts little more" for pain intensity on Wong Baker's scale and 21.7% reported all four quadrants as sites of pain. Conclusions: The pain experienced after separator insertion was associated with sex and age. Females experienced more pain than males and patients between the age range of 21 and 36 years suffered more pain during mastication than between 9 and 20 years old.

Objectives: This cross-sectional study examined sex differences in Health-Related Quality of Life (HRQoL) among seniors with Type 2 Diabetes Mellitus (T2DM). Methods: Data from the Korea National Health and Nutrition Examination Survey (2008-2020) were analyzed. The EuroQol-5 Dimensions (EQ-5D), a measure of HRQoL, was used. It comprises five dimensions: mobility, self-care, usual activity, pain/discomfort, and anxiety/depression, each with three levels. Results: Analysis of 3,826 older adults with T2DM showed a significant increasing trend in the EQ-5D Index from the 4th survey phase onwards (P for trend < 0.001 for both men and women). Men consistently reported higher EQ-5D levels than women across all survey years. Women's EQ-5D levels remained lower than men's, maintaining a decade-old disparity (P < 0.05). Men scored significantly higher (P < 0.05) in most EQ-5D domains, except for self-care and anxiety/depression, resulting in a higher total EQ-5D Index (P = 0.001). Increased comorbidities were strongly associated with lower EQ-5D levels in both sexes. Additionally, there was a negative correlation between the EQ-5D Index and refined grain intake for both sexes (P for trend < 0.001), with high-EQ-5D groups consuming fewer refined grains. Women in the high-EQ-5D group consumed more nuts, vegetables, and meat compared to men (P for trend < 0.05). Conclusions: Our study highlights the sex disparities in HRQoL among older adults with T2DM. The findings suggest the need for tailored treatment guidelines aimed at improving the HRQoL of elderly T2DM patients, with a focus on their sex-specific characteristics. Implementing these tailored guidelines could enhance the HRQoL of older women with T2DM and promote more equitable healthcare outcomes. This underscores the importance of considering sex differences to comprehensively improve the well-being of this population.

This study is to research the comprehensive recognition of male elderly about the sex life in old age. We collected data through face to face interview after obtaining the consents of 13 male elderly over 65 years old who reside in Kimhae Gyeongnam and Busan. The result of study showed that the sexual recognition of male elderly participants include the core concept of , , < the sex with restriction> and . In other words, the male elderly recognized the sexual life of old age as a natural and instinctive thing, the restrictions still exist including the negative recognition of family and surrounding people and diseases but it is found that the improvement of social recognition about sexual desire, the sex education and aggressive support for the various solutions are required. As the sexual awareness of the elderly is the comprehensive and broad study, the amalgamative and integrated study should be continued in the various fields. Through this, we tried to suggest the basic documents to the effective and differentiated individual sex consultation based on the empirical characteristics and desire of male elderly, and customized sex education and the development of local society program.

As the occurrence of a crime is dependent on different factors, their correlations are beyond the ordinary cognitive range. Owing to this limitation, systems face difficulty in correlating various factors, thereby requiring the assistance of artificial intelligence (AI) to overcome such limitations. Therefore, AI has become indispensable for crime prediction. Crimes can cause severe and irrevocable damage to a society. Recently, big data has been introduced for developing highly accurate models for crime prediction. Prediction of night crimes should be given significant consideration, because crimes primarily occur during nights, when the spatiotemporal characteristics become vulnerable to crimes. Many environmental factors that influence crime rate are applied for crime prediction, and their influence on crime rate may differ based on temporal characteristics and the nature of crime. This study aims to identify the environmental factors that influence sex and theft crimes occurring at night and proposes an artificial neural network (ANN) model to predict sex and theft crimes at night in random areas. The crime data of A district in Seoul for 12 years (2004-2015) was used, and environmental factors that influence sex and theft crimes were derived through multiple regression analysis. Two types of crime prediction models were developed: Type A using all environmental factors as input data; Type B with only the significant factors (obtained from regression analysis) as input data. The Type B model exhibited a greater accuracy than Type A, by 3.26 and 9.47 % higher for theft and sex crimes, respectively.

Objective: In this study, we investigated sex- and region-specific effects of acute trimethyltin (TMT) exposure on mitochondrial biogenesis. Methods: We treated TMT to primary neuronal cultures and 4-week-old male and female mice. We measured the mitochondrial DNA copy numbers using the quantitative polymerase chain reaction method. We also measured mitochondrial biogenesis related genes (sirtuin-1, estrogen-related receptor alpha, cytochrome C oxidase subunit IV) by western blotting. Results: The mitochondrial DNA copy number increased in the primary hippocampal neuron; however, it decreased in the primary cortical neuron. The mitochondrial copy number increased in the hippocampus and decreased in the cortex in the TMT treated female mice, though the mitochondrial copy number increased in both cortex and hippocampus in the TMT treated male mice. TMT treatment increased sirtuin-1 expression in the male hippocampus but did not in the female brain. In the female brain, estrogen-related receptor alpha expression decreased in the cortex though there is no significant change in the male brain. The protein level of mitochondrial protein, cytochrome C oxidase subunit IV, increased in both cortex and hippocampus after TMT injection in male mice brain, but not in female mice brain. Conclusion: Our data suggest that acute TMT exposure induces distinct sex-specific metabolic characteristics in the brain before significant sexual maturation.

Purpose: This study examines and compares the differences between self-esteem and health promotion behavior of health department and non-health department college students. Method: The research instruments were as follows : The first one is RSES developed by Rosenberg and translated into Korean by Jeon. The second one is HPLP developed by Walker et al, and including six subareas by Lee and modified to be suitable to Korean culture by Suh. Data were statistically analyzed with SPSS PC/12.0. Results : 1. Comparison of self-esteem had no significant difference(p=.190) and health promotion behaviors had significant differences(p=.000) between the two groups. 2. According to general characteristics and health-related characteristics, the differences of self-esteem in health department showed significant differences in grade(p=.020), sex(p=.000), age(p=.000), parents' economic conditions(p=.048), and smoking(p=.030) while non-health departments revealed significant differences in grade(p=.003), sex(p=.000), age(p=.000) and smoking(p=.001). 3. According to general characteristics and health-related characteristics, the differences of health promotion behaviors in health department showed significant differences in grade(p=.008), sex(p=.021), age(p=.000) and parents' economic conditions(p=.017) while non-health department revealed significant differences in sex(p=.000) and age(p=.000). 4. There were positive correlations between self-esteem, health promotion behaviors and subareas in health department (r=.422) and non-health department (r=.383). Conclusion: There were significant positive correlations between self-esteem and health promotion behaviors in health and non-health department college students. Therefore, health related programs should be developed to enhance self-esteem and health management by college students can influence themselves on self-esteem and health promotion behaviors.

Background/Aims: Sex differences in the prognosis of heart failure (HF) have yielded inconsistent results, and data from Asian populations are even rare. This study aimed to investigate sex differences in clinical characteristics and long-term prognosis among Korean patients with HF. Methods: A total of 5,625 Korean patients hospitalized for acute HF were analyzed using a prospective multi-center registry database. Baseline clinical characteristics and long-term outcomes including HF readmission and death were compared between sexes. Results: Women were older than men and had worse symptoms with higher N-terminal pro B-type natriuretic peptide levels. Women had a significantly higher proportion of HF with preserved ejection fraction (HFpEF). There were no significant differences in in-hospital mortality and rate of guideline-directed medical therapies in men and women. During median follow-up of 3.4 years, cardiovascular death (adjusted hazard ratio [HR], 1.38; 95% confidence interval [CI], 1.07-1.78; p = 0.014), and composite outcomes of death and HF readmission (adjusted HR, 1.13; 95% CI, 1.01-1.27; p = 0.030) were significantly higher in men than women. When evaluating heart failure with reduced ejection fraction (HFrEF) and HFpEF separately, men were an independent risk factor of cardiovascular death in patients with HFrEF. Clinical outcome was not different between sexes in HFpEF. Conclusions: In the Korean multi-center registry, despite having better clinical characteristics, men exhibited a higher risk of all-cause mortality and readmission for HF. The main cause of these disparities was the higher cardiovascular mortality rate observed in men compared to women with HFrEF.

We reviewed sex-change patterns in the wrasses Halichoeres poecilopterus, H. tenuispinis, Pteragogus flagellifer, and Pseudolabrus sieboldi inhabiting the coastal waters of Jeju, Korea, based on the sex distribution according to standard length and sex characteristics of the gonads. Halichoeres poecilopterus, H. tenuispinis, Pt. flagellifer, and Ps. sieboldi are protogynous hermaphroditic fish. Histological observations revealed that these wrasses are undelimited type 2 species because testicular tissue(spermatogenesis area) appears in most parts of the gonads during ovary of degenerative stage. Both initial- and terminal-phase males were present in the investigated populations, indicating that Halichoeres poecilopterus, H. tenuispinis, and Ps. sieboldi are of the diandric type. In contrast, Pt. flagellifer is considered a monandric type, because all males in the investigated populations were terminal-phase males produced via sex change from functional females.
