Background: The purpose of this study is to analyze the factors affecting the unmet healthcare needs of older people with chronic diseases in Korea and provide a basic research report to strengthen their access to medical care. Methods: In the 2020 older people survey data, 8,182 older people aged 65 or older who were diagnosed with one or more chronic diseases were the final subjects of the study. According to Andersen's behavioral model used in unmet healthcare needs, independent variables were composed of predisposing factors, possible factors, and necessary factors, and whether or not unmet healthcare needs was set as dependent variable. Results: Of the older people with chronic diseases, 1.6% experienced unmet healthcare needs, of which 55.9% experienced unmet healthcare needs for reasons related to economic burden, 31.6% physical constraints, and 12.5% time constraints. As a result of the analysis, older people with chronic diseases were more likely to experience unmet healthcare needs if they were relatively low in age, low in education level, no spouse, low in household income, poor subjective health, complex chronic diseases, and functional restrictions. However, by major reasons for experiencing unmet healthcare needs, living in rural areas were more likely to experience unmet healthcare needs due to physical constraints, and those who participated in economic activities and who had were more likely to experience unmet healthcare needs due to time burden. These results were not derived when only unmet healthcare needs was set as the dependent variable. Conclusion: This study emphasizes the need for an approach by cause of unmet medical occurrence by suggesting that there are differences in influencing factors by reason for experiencing unmet healthcare needs.

Background: This study was to investigate the effects of coordinative locomotor training(CLT) using elastic bands on pain, dynamic balance, muscle strength, and muscle activity of female college students with patellofemoral pain syndrome(PFPS). Design: Randomized Controlled Trial Methods: Twenty-six female college students with PFPS were assigned randomly to an experimental(n=13) or control(n=13) group. The experimental group performed CLT using an elastic band. The control group performed squat exercises to strengthen muscle strength. The 30-minute inter- vention was applied a total of twelve times, three times a week for four weeks. All subjects measured the pain, the muscle strength, the dynamic balance, and the muscle activity(VL/VM ratio) before and after intervention. A paired t-test was used for the determination of differences before and after treatment, and an independent t-test was used for the determination of differences between treatment groups. Results: As a result of comparison within groups, the experimental group showed significant differences in pain, muscle strength, dynamic balance, and VL/VM ratio after the experiment(p<0.05), and the control group showed significant differences in pain, muscle strength, and dynamic balance after the experiment(p<0.05). In comparison between the two groups, the experimental group showed more significant differences in pain, dynamic balance, and VL/VM ratio than the control group(p<0.05), and the control group showed more significant differences in muscle strength than the experimental group(p<0.05). Conclusion: Based on these results, CLT using elastic bands effectively improved the pain, muscle strength, dynamic balance, and VL/VM ratio of female college students with PFPS.

Objectives: The purpose of this study was to examine search trends and their meanings for major uninsuired Korean medicine (KM) treatments through analysis of an online portal search results. Methods: Keywords searches were performed using Naver Datalab on 4 July 2023. From January 2016 to June 2023, monthly relative search volume (RSV) for keywords 'pharmacopuncture', 'Chuna', and 'needle-embedding therapy', and 'herbal decoction' were extracted with a score between 0 and 100. For the obtained RSVs, longitudinal changes over time, characteristics according to sex and age group, and correlations between them were investigated. Results: The ranking of RSV for each keyword has changed from 'Chuna', 'herbal decoction', 'needle-embedding therapy', and 'pharmacopuncture' to 'Chuna', 'herbal decoction', 'pharmacopuncture', and 'needle-embedding therapy' after 2019. Overall, the RSV of needle-embedding therapy continuously decreased, while that of pharmacopuncture continuously increased. In 2019, a rapid increase in the RSV of Chuna was observed, and in 2020, a rapid increase in the RSV of herbal decoction was observed. There was a difference in the longitudinal change pattern of RSV for the keywords by age group. Importantly, in the elderly, changes in RSV were observed in a favorable pattern to KM treatment. Conclusion: Our findings enable estimation of the public's interest and its changes for the four uninsuired KM treatment, and can be used as basic data to strengthen health insurance coverage in Korea. Specifically, changes in interest in KM treatments according to sex and age can be referred to.

Background: The serratus anterior (SA) is a muscle that performs protraction of the scapulothoracic joint and plays a role in stabilizing the scapula. Imbalances or weaknesses in SA activation are associated with a variety of shoulder dysfunctions, making selective SA strengthening important for rehabilitation. Objects: We aimed to compare the muscle activation of the pectoralis major (PM), SA, external oblique (EO), and internal oblique (IO) during the push-up plus (PUP) exercise with isometric hip adduction (HA) and abdominal drawing-in maneuver (ADIM). Methods: Nineteen healthy male participants performed three PUP exercises: standard PUP, PUP with ADIM, and PUP with HA. Surface electromyography was used to measure and analyze the muscle activity for PM, SA, EO, and IO. Results: PUP with HA showed the lowest PM activity and highest SA activity, and no significant difference was observed between PUP and PUP with ADIM. PUP with ADIM showed significantly the highest EO and IO activity, followed by PUP with HA and PUP. Additionally, PUP with HA showed the lowest PM/SA ratio, and no significant difference was noted between PUP and PUP with ADIM. Conclusion: PUP with HA was able to show high SA muscle activity while reducing PM muscle activity. In addition, PUP with HA can lead to higher EO and IO muscle activity than standard PUP. This exercise could be used as a practical exercise method to selectively strengthen SA and improve scapular muscle stability during early shoulder rehabilitation.

Purpose: This study aimed to evaluate and assess the response capabilities and educational needs of 119 emergency medical technicians (EMTs) in chemical accidents. Methods: A self-reported questionnaire was completed by 167 119 EMTs between December 1st and December 31, 2023. The questionnaire comprised 8 questions on general characteristics, 2 on chemical accidents experienced by the participants, 29 on response capabilities, and 15 on educational needs. Data analysis was performed using t-tests, analysis of variance, Duncan's test for post-hoc analysis, and Pearson's correlation coefficient, using SPSS 27.0. Results: The participants scored 2.69 points on response capacity to chemical accidents. The EMT-Paramedics scored high in 'patient triage,' 'patient treatment,' 'patient transport,' and 'collaborative support' (F=3.924, p=.010; F=5.843, p=.001; F=3.698, p=.013; F=5.272, p=.002), followed by educational experience (t=-4.962, p<.001; t=-2.685, p=.008; t=-3.455, p=.001; t=-3.593, p<.001; t=-3.034, p=.003). The participants scored 4.19 points on educational needs, with high scores for 'patients treatment and transport' (4.280.93). The scores for 'patient triage competency', and 'patient triage' (r=.169, p=.024) correlated positively. Furthermore, the scores for 'patient treatment competency' and all sub-factors of educational needs (r=.185, p=.013; r=.215, p=.004; r=.199, p=.008; r=.190, p=.011; r=.197, p=.008) correlated positively. Conclusion: To strengthen the response capabilities of 119 EMTs, it is imperative to develop an educational program that focuses on first-aid responses.

Objectives: Nitric oxide is the most important mediator of penile erection after the onset of sexual excitement. It activates cyclic guanosine monophosphate (cGMP), increasing penile blood flow. Most pharmaceutical medications prevent enzyme phosphodiesterase type 5 (PDE-5) from breaking down cGMP, thus keeping its level high. However, due to the adverse effects of pharmacological therapies, herbal drugs that improve sexual function have gained attention recently. This study aimed to investigate the combined effects of ginseng, Tribulus terrestris, and L-arginine amino acid on the sexual performance of individuals with erectile dysfunction (ED) using the 5-item version of the International Index of Erectile Function (IIEF-5) questionnaire. Methods: Over three months, 98 men with erectile dysfunction were randomly assigned to receive either 500 mg of herbal supplements or placebo pills. Each herbal tablet contained 100 mg of protodioscin, 35 mg of ginsenosides, and 250 mg of L-arginine. Results: The results showed that the changes in the average scores of ILEF-5 within each group before and after the intervention indicated that all parameters related to the improvement of sexual function in patients with erectile dysfunction improved in the herbal treatment group (p < 0.001). The herbal group significantly improved IIEF-5 scores in nondiabetics (p < 0.05). However, there was no significant difference in the changes of IIEF-5 scores between the two intervention and control groups in diabetic patients. Conclusion: In conclusion, ginseng, Tribulus terrestris, and L-arginine have properties that increase energy and strengthen sexual function, making them suitable for patients with sexual disorders.

Objectives : This study aimed to explore the association between depression and perceived stress, viral anxiety, reassurance-seeking behavior, and poor sleep quality among the general population in Bangladesh, with self-efficacy as a possible mediator. Methods : Data on stress and anxiety during the pandemic in Bangladesh were collected through an online survey from September 16, 2021 to October 4, 2021. Viral anxiety and depression were measured using the Bangla version of Stress and Anxiety to Viral Epidemic-6 (SAVE-6) and Patient Health Questionnaire-9 (PHQ-9), respectively. Self-efficacy was measured by the General Self-efficacy (GSE) scale. Reassurance-seeking behavior related to the coronavirus disease 2019 infection was measured by the Coronavirus Reassurance-Seeking Behaviors Scale (CRBS). Results : The CRBS showed a significant correlation with SAVE-6 (r=0.281, p<0.001) and PHQ-9 (r=0.227, p<0.001). People with higher anxiety, reassurance-seeking behavior, and poor sleep quality had lower self-efficacy, which led to depression. In contrast, perceived stress increased self-efficacy. The psychological factors impacted depression directly as well as indirectly, and self-efficacy mediated the association. Conclusions : Viral anxiety, reassurance-seeking behavior, perceived stress, and poor sleep quality have a close correlation with depression both directly and indirectly. Self-efficacy can be a mediating factor in the association between psychological distress and depression. Viral anxiety, reassurance-seeking behavior, and poor sleep quality reduce self-efficacy. On the other hand, perceived stress can strengthen self-efficacy.
