  • This study utilized the raw data from the Community Health Survey (2023) to compare differences in body function, activity, participation, environment, personal factors, and suicidal ideations between elderly individuals aged 65 and older living alone and those living with families in Korea. The study subjects consisted of 80,618 elderly individuals aged 65 and older. Cross-tabulation analysis χ2-test), independent sample t-test, and logistic regression analysis were conducted. The results indicated that for both elderly individuals living alone and those living with families, age(p<.001), smoking(p<.001), stress(p<.001), depression experience(p<.001), and falls experiences(p<.001) were risk factors that increased suicidal ideations. Conversely, educational level(p<.05), income level(p<.001), subjective health status(p<.001), social participation(p<.001), economic activity(p<.001), community environment(p<.001), and social relationships were protective factors that reduced suicidal ideations. These findings demonstrate that demographic characteristics and individual health status significantly influence suicidal ideation in the elderly, while social factors contribute to a decrease in suicidal ideation. Furthermore, considering the differences found between elderly individuals living alone and those living with families regarding hypertension and gender, differentiated interventions for suicide prevention are necessary.

  • Purpose : The purpose of this study is to investigate nursing students' levels of and relationships between college-related stress, self-efficacy, social support, and interpersonal skills. Methods : This study involved 352 nursing students at K University in B City, each who understood the study's purpose and agreed to participate in the study. The study's data were collected between April 8 and 19, 2019 and were analyzed using the SPSS for Windows 22.0 program based on frequencies, percentages, means, and standard deviations as well as a t-test, analysis of variance, post-hoc test, and correlation analysis results. The Scheffe test was performed for the post-hoc test, and the Pearson correlation coefficient was employed for the correlation analysis. Results : College-related stress showed statistically significant negative correlations with self-efficacy (r=-.310, p<.001), social support (r=-.312, p<.001), and interpersonal skills (r=-.226, p<.001). However, self-efficacy exhibited statistically significant positive correlations with social support (r=.548, p<.001) and interpersonal skills (r=.524, p<.001), and social support showed a statistically significant positive correlation with interpersonal skills (r=.644, p<.001). Therefore, higher levels of self-efficacy and social support and a lower level of college-related stress result in corresponding higher levels of interpersonal skills. Conclusion : Based on the results of this study, it is necessary to find measures to lower nursing students' college-related stress and increase their self-efficacy and social support, as well as to develop and operate specific intervention programs that can help enhance their interpersonal skills.

  • Objectives: The objective of this study was to investigate clinical and neuropsychological factors associated with treatment response and adverse events of atomoxetine in children with attention-deficit/hyperactivity disorder (ADHD) in Korea. Methods: Children with ADHD were recruited at the Department of Psychiatry of Asan Medical Center from April 2015 to April 2018. Diagnoses of ADHD and comorbid psychiatric disorders were confirmed with the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version. The subjects were subsequently treated with atomoxetine for 12 weeks and illness severity was scored using the ADHD Rating Scale, Clinical Global Impression-Severity scale (CGI-S) and/or Improvement scale (CGI-I), at pre- and post-treatment. They also completed the Advanced Test of Attention (ATA), while their caregivers completed the Korean Personality Rating Scale for Children (KPRC) at pre- and post-treatment. Independent t-test, Fisher's exact test, ${\chi}^2$ test, mixed between-within analysis of variance and correlation analysis were used for statistical analysis. Results: Sixty-five children with ADHD (mean age: $7.9{\pm}1.4years$, 57 boys) were enrolled, of which, 33 (50.8%) were treatment responders. Scores on the social dysfunction subscale of the KPRC (p=0.021) and commission errors on the visual ATA (p=0.036) at baseline were higher in treatment non-responders than in responders; however, the statistical significances disappeared after adjusting for multiple comparisons. Mood changes were also observed in 13 subjects (20.0%), and three of them discontinued atomoxetine due to this. Additionally, atomoxetine-emergent mood change was observed more frequently in girls (p=0.006), while the intelligence quotient (p=0.040) was higher in those subjects with mood changes than in those without. Conclusion: The results of our study suggest that clinical and neuropsychological factors could be associated with treatment response or adverse events of atomoxetine in children with ADHD. Further long-term studies with larger samples are needed.

  • The purpose of this study was to evaluate the bioequivalence of two amlodipine maleate tablets, SKAD tablet (SK Pharma. Co., Ltd., Seoul, Korea, reference drug) and A-PINE tablet (Daewon Pharm. Co., Ltd., Seoul, Korea, test drug), according to the guidelines of Korea Food and Drug Administration (KFDA). Twenty-four healthy male volunteers, $22.79\;{\pm}\;1.86$ years in age and $70.08\;{\pm}\;8.68$ kg in body weight, were divided into two groups and a randomized $2\;{\time}\;2$ crossover study was employed. After a tablet containing 6.42 mg of amlodipine maleate was orally administrated, blood was taken at predetermined time intervals over a period of 144 hr and concentrations of amlodipine in plasma were monitored using LC-MS/MS. Pharmacokinetic parameters such as $AUC_t$ (the area under the plasma concentration-time curve from time zero to 144 hr), $C_{max}$ (maximum plasma drug concentration) and $T_{max}$ (time to reach $C_{max}$) were calculated and analysis of variance (ANOVA) test was utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t$ and $C_{max}$, and untransformed $T_{max}$. No significant sequence effect was found for all of the bioavailability parameters indicating that the crossover design was properly performed. The 90% confidence intervals of the $AUC_t$ ratio and the $C_{max}$ ratio for A-PINE/SKAD were $log\;0.9429{\sim}log \;1.1476$ and $log\;0.9l46{\sim}log\;1.1488$, respectively. Since these values were within the acceptable bioequivalence intervals of $log\;0.80{\sim}log\;1.25$, recommended by KFDA, it was concluded that A-PINE tablet was bioequivalent to SKAD tablet, in terms of both rate and extent of absorption.

  • The purpose of this study was to examine the health promoting behavior of university students and its related factors. A self-administered questionnaire survey was carried out for 1,031(male, 477, female, 554) students from 7 universities in Taegu from March 10 to April 15 2000. Collected data were analyzed by the $X^2$-test, t-test, ANOV A and structural equation modeling analysis. The results of this study were as follows; Mean score of health promoting behavior of women was higher than mean score of men(p〈0.01). According to the subordinate fields, female students showed significantly higher scores in the fields of stress management, nutrition, personal relations and alcohol-cigarette(p〈0.05). And in male students, the only fields of exercise had meaningfully higher score(p〈0.01). The highest degree of performance was marked in alcohol-cigarette field in female, and interpersonal field in male. In Both male and female students, the lowest field was health responsibility. The mean score of health promoting behavior showed significant differences in intermediating factors such as age, health education and grade in male, and such as grade, pocket money for a month, taking health education, perceived body shape and gastrointestinal symptoms in female(p〈0.05). The mean score of health promoting behavior showed significant differences in cognitive-perceptual factors and cues to action such as perceived health status, perceived benefits, perceived barriers, and health concern of parents in both male and female(p〈0.05). By the results of structural equation modeling analysis in male students, the economic status, gastrointestinal symptoms and perceived body shape as lean had significant direct effects on cognitive-perceptual factors($\mid$T$\mid$〉2.0). Grade and health concern of parents had significant direct effects on health promotion behaviors($\mid$T$\mid$〉2.0). In female students, perceived body shape as lean and perceived body shape as fat had significant direct effects on cognitive-perceptual factors($\mid$T$\mid$〉2.0). Grade, pocket money and health concern of parents had significant direct effects on health promotion behaviors($\mid$T$\mid$〉2.0). On the consideration of above findings, it is recommended that perceived health status and perceived benefits should be raised and perceived barriers should be lowered to increase health promoting behaviors, by means such as institutional approach which can enhance the primary prevention for a disease. In addition, the health policy for improving parents' concern about health as well as university students, through various ways such as health education, consulting, and health program, should be employed.

  • Background: This study aimed to analyze the on heart rate, blood lactate concentration, packed cell volume (PCV) and hemoglobin (Hb) response after conducting exercise in endurance horses. Methods: A total of 20 healthy 3-9-years-old Jeju crossbreed mares ($5.95{\pm}2.24$ year) of age and $312.65{\pm}13.59kg$ of weight) currently participating the endurance competition were used. The field tests selected for the experiment was gallop (approximately 8.3 m/s) along the selected 2.5 km course (a natural forest trail, not artificial road; a closed loop course). The horses were divided into three groups according to their age; 3-4 years of age (G1, $3.29{\pm}0.49$ year), 6-7 years of age (G2, $6.42{\pm}0.53$), and 8-9 years of age (G3, $8.50{\pm}0.55$). The measurements times for the heart rate, blood lactate concentration, PCV, and Hb analysis were conducted before exercise (T0), shortly after exercise (T1), 15 min after exercise (T2), and 30 min after exercise (T3), respectively. Data was analyzed using an analysis of covariance (ANCOVA) for repeated measures with times and groups. Results: The results of the comparison depending on the passage of rest time after exercise suggest that the heart rate and blood lactate concentration of three groups at T2 significantly decreased compared to T1 (p < 0.001). PCV of the G2 and G3 groups were significantly decreased at T2 compared to T1 (p < 0.01). Hb values at G2 (p < 0.01) and G3 (p < 0.001) groups were significantly decreased at T2 as compared to T1. However, heart rate, blood lactate concentration, PCV and Hb level at T1 showed no difference in the comparison of horses from different age groups with the exception of G3 group in terms of heart rate. Conclusion: The physiologic and hematological responses of horses during recovery time after 2,500 m exercise with gallop were no significant difference among the groups. These data are useful as a response evaluation method for training of endurance horses.

  • This thesis will study the determinants of consumer satisfaction based on the disconfirmation theory. The proposed questions are first, to find out if desire and expectation are conceptually distinct. Second, to study the effects of desire, expectation, perceived performance, desire congruency, and expectation congruency on clothing satisfaction. The data used in this thesis were obtained from a two stage longitudinal survey. SPSS WIN 8.0 was used for the analysis and the following method such as mean, correlation, t-test, hierarchical regression were applied. The results indicate that first, according to the correlation analysis and crosstab analysis, satisfaction and desire were perceived as two different concepts. Second, using the hierarchical regression analysis to compare the effects of determinants of consumer satisfaction, the model of desire, expectation, performance, desires congruency, expectations congruency best explain the clothing satisfaction. Among them, effects of performance had the strongest impact. Expectation did not influence satisfaction but desire did.

  • The purpose of this study was to investigate the relationships between body-calthexis and clothing image preferences in male college students. The sample included 28 male college students and an instrument was developed based on the previous studies. The statistical analyses used for this study were factor analysis cluster analysis and t-test. The result of factor analysis showed that body-cathexis consisted of four areas of body parts: face/head upper body middle body and lower/total body. Clothing image preferences consisted of 'strong vs weak' 'soft vs hard' 'young vs mature' 'mannis vs feminine' and 'distinguished vs undistinguished' images. Cluster analysis revealed that male college students are segmented into two groups. and the two groups differed in regard to clothing image preferences such as 'strong vs weak' 'young vs mature' and 'mannish vs feminine' images. In addition the two consumer segments were different concerning body-cathexis for middle body and all body areas combined. The consumers who preferred feminine weak and mature clothing images were more satisfied with their middle area of the bodies and all body areas combined.
