Purpose: This study proposes a concert oriented music therapy (COMT) program which takes into account the personal and social factors of depression, and its clinical effects were validated on elderly persons with visual impairments who were susceptible to depression. The experiment was conducted on 34 elderly persons with visual impairments, randomly allocated to either the experimental group (n = 15) or the control group (n = 19). The COMT program was applied 20 times in total to the experimental group for 110 minutes every other week, for a duration of 10 months. The depression level was evaluated using the Korean form of the Geriatric Depression Scale (KGDS). The experimental results showed that the average KGDS score in the experimental group decreased by 4.1 points (19.4%), from 21.0 to 16.9, whereas it increased by 1.16 points (5.8%), from 19.95 to 21.11, in the control group. The reduction in the depression level was significant for the following 4 depression factors : decreased social interest (40%), negative thinking and the unhappiness feeling (20%), emotional discomfort (16.3%), and cognitive dysfunction (7.6%), whereas it was negligible in the factors of physical weakening and decreased vitality. The COMT program reduced the KGDS scores of the experimental group regardless of their experience in musical performance. In conclusion, the proposed COMT program proved to be efficacious in alleviating depression in elderly persons with visual impairments. In particular, it proved highly effective in helping with decreased social interest, namely, the social factor of depression which is not properly considered in existing music therapy methods.

As the development of renewable energy expands internationally to cope with global warming and climate change, the share of wind power generation has been gradually increasing. Although wind farms can produce electric power for 24 h a day compared to solar power plants, Their interfere with the operation of nearby radars or communication equipment must be analyzed because large-scale wind power turbines are installed. This study analyzed whether a land radio station can receive sufficient signals when a ship sailing outside the offshore wind farm transmits distress signals on the VHF band. Based on the geographic information system digital map around the target area, wind turbine CAD model, and wind farm layout, the area of interest and wind farm were modeled to enable numerical analysis. Among the high frequency analysis techniques suitable for radio wave analysis in a wide area, a dedicated program applying physical optics (PO) and shooting and bouncing ray (SBR) techniques were used. Consequently, the land radio station could receive the electromagnetic field above the threshold of the VHF receiver when a ship outside the offshore wind farm transmitted a distress communication signal. When the line of sight between the ships and the land station are completely blocked, the strength of the received field decreases, but it is still above the threshold. Hence, although a wind farm is a huge complex, a land station can receive the electromagnetic field from the ship's VHF transmitter because the wave length of the VHF band is sufficiently long to have effects such as diffraction or reflection.

This study aimed to evaluate the effectiveness of Korean rehabilitation treatement for patients with post-TKR. The medical records of inpatients undergoing Korean rehabilitation treatment after TKR from 2016.01.01. to 2021.12.31. during the admission, were analyzed retrospectively. The effect of treatment was evaluated by using a numeric rating scale(NRS) and range of motion(ROM) of knee. Statistical analysis was done using the IBM SPSS statistics 26 program. If the period of hospitalization was within 7 days or change of NRS and ROM was not recorded properly, the case was excluded. All inpatients received acupuncture treatment, Electro-acupuncture. Soyeom pharmaco-acupuncture were used at a high rate. Blood letting cupping therapy, dry cupping therapy, Interferential Current Therapy(ICT) continuous passive motion(CPM), cryotherapy were used at a high rate. A significant improvement was noted when comparing the NRS and knee ROM results at the time of admission and discharge. Korean medical rehabilitation can be effectively used for patients who have undergone TKR, to relieve pain and enable returning to daily activities. It is expected to be helpful in future studies of post-TKR in Korean Medicine. Also It can be used for medical treatment of post-TKR in Korean Medicine Hospital and clinic. However, further research with a high level of evidence is necessary to support this finding.

Objectives: This study examined the effectiveness of Korean medical treatment for two patients complaining of discomfort after receiving Pfizer COVID-19 vaccine. Methods: The patients were hospitalized for 50 days and 12 days, respectively. They were treated with herbal medicine, acupuncture, electroacupuncture, and moxibustion. We used the Numerical Rating Scale (NRS) on numbness in extremities and headache, Manual Muscle Testing Grading System (MMT), Criteria for Sweating Categorization, and 36-Item Short Form Health Survey (SF-36) to evaluate the clinical effects of the treatment. Results: In Case 1, headache improved from peak NRS 9 and average NRS 7 on admission day to both NRS 3 on discharge. The SF-36 score was also increased, suggesting that the quality of life was improved. In Case 2, numbness in the extremities improved from NRS 8 on the day before admission to NRS 2 on discharge, and general condition also improved. Conclusions: This study suggests that Korean medicine can be an effective treatment for patients who experience long-lasting discomfort after being vaccinated with COVID-19, but with no abnormal findings in the examination.

Purpose: The purpose of this study was to investigate the effect of McConnell taping and Kinesio taping on pain and lower extremity joint angles when patients with patellofemoral pain syndrome (PFPS) ascend stairs. Methods: Fifty young adults who were experiencing anterior knee pain due to PFPS were selected as participants. Then, 25 patients were randomly assigned to the McConnell taping group and 25 to the Kinesio taping group. Pain and lower extremity joint angle were measured while ascending stairs before and after the intervention. A paired t-test was performed to evaluate the amount of change in the parameter values after the intervention within the groups, and an independent t-test was used to compare the results of the groups. Results: In the within-group comparisons, a statistically significant difference was found in both groups between the anterior knee pain scale scores recorded before and after the intervention (p < 0.05). A statistically significant difference was also found between the groups (p < 0.05). Comparison of the lower extremity joint angles at initial contact, loading response, terminal stance, and pre-swing within the groups showed that there were statistically significant differences in the hip, knee flexion, abduction, lateral rotation, and dorsiflexion angles in both the McConnell and Kinesio taping groups (p < 0.05). There was also a statistically significant difference in all angles between the groups during the following events (p < 0.05): (1) at initial contact, (2) at loading response (except hip flexion angle), (3) at terminal stance (except hip flexion and lateral rotation angles), and (4) at pre-swing (except hip, knee abduction, and inversion angles). Conclusion: McConnell taping and Kinesio taping both effectively improved the occurrence of knee pain and the lower extremity joint angles during stair ascent in patients with PFPS. However, McConnell taping had a significant impact on pain reduction and lower extremity joint angles compared to Kinesio taping.

The purpose of this study is to develop music psychotherapy program applying the Inner Family System(IFS) to reduce adult depression and improve self-esteem and to verify its effectiveness. For this, literature search and theoretical basis were prepared, and validity was secured through a demand survey and evaluation by experts. After going through the preliminary program, the final program consisting of 10 sessions was developed after revision and supplementation. To verify the effectiveness of the program, 25 people who met the selection criteria with a score of 20 or higher on the Depression Scale(CES-D) were selected. Of the 25 subjects, 10 subjects in the experimental group, 10 subjects in the control group, and 5 subjects in the preliminary group were randomly assigned and analyzed as final study subjects. The experimental group performed 10 sessions of music psychotherapy applying IFS twice a week for 90 minutes, and the control group did not receive any treatment. As a result of data analysis, first, it was confirmed that there was a difference between the experimental group and the control group in the change patterns according to the measurement period of overall depression and the sub-factors, depressive emotion, interpersonal emotion, and physical depression score. Second, the effects were statistically significant on overall self-esteem and sub-factors such as self-deprecation, relationship with others, leadership and popularity, assertion and anxiety. Third, it was confirmed that the pattern of change according to the measurement period of the IFS score differed between the experimental and control groups.

Purpose: Acute pesticide poisoning is lethal and can lead to death. A few studies about the effects of acute pesticide poisoning have focused on the immune system. In the current study, we preliminarily investigated the changes in blood inflammatory cytokine levels in acute pesticide poisoning patients. Methods: In this study, we prospectively investigated the inflammatory cytokines in patients with acute pesticide poisoning. This study included patients admitted from February 2021 to November 2021 with a diagnosis of intentional poisoning by pesticide ingestion. The inflammatory cytokines measured were IFN-γ, IL-1β, IL-6, and TNF-α. Results: Totally, 27 patients were enrolled in this study. The types of pesticide ingested were glufosinate (n=6), glyphosate (n=8), organophosphate (n=4), pyrethroid (n=2), and others (n=7). The levels of inflammatory cytokines obtained were as follows: IFN-γ 2.78±8.03 pg/ml, IL-1β 2.62±2.03 pg/ml, IL-6 44.58±80.16 pg/ml, and TNF-α 11.80±15.60 pg/ml. The overall mortality rate was 11.1% (3/27), and levels of IL-1β and TNF-α were significantly higher in the death group compared to the survival group. Conclusion: Increased levels of IL-6 and TNF-α were observed in patients with acute pesticide poisoning. IL-1β and TNF-α were significantly higher in the death group as compared to the survival group. Our results indicate the occurrence of an inflammatory response due to the activation of immune cells by pesticide poisoning. Future large-scale studies need to be conducted to investigate the application of inflammatory cytokines as predictors and therapeutic targets.

Purpose: The purpose is to prevent accidents by predicting disasters through the analysis of near-miss. Method: In this study, a near-miss literature review and data were collected at construction sites, and a questionnaire survey was conducted to use logistic regression analysis and decision tree analysis to classify the possibility of near-miss connection. Result: As a result of analyzing the effects of near-miss types on mental, physical, and safety habits and behaviors, the factor with a high influence on the body is the need for near-miss management, the type of job is electricity·information communication, and health status in order, and the mental factor is the construction scale The influence was high, and the factors with the highest influence on the habit behavior factors were analyzed in the order of experience, number of serious injuries, and occupation in order of illusion, inappropriate work instructions, and body parts. Through decision tree analysis, factors and patterns that affect the possibility of a near-miss being a surprise accident were identified. Conclusion: Construction site officials consider the observation of near-miss and mentally and physically. Specific management of the relevance of physical aspects to near-miss should be implemented, and a work environment in which serious accidents are reduced is expected through personnel allocation, work plans, work procedures and methods, and feedback so that inappropriate work instructions do not lead to near-miss.

This study evaluated the biochemical methane potential (BMP) of primary sludge, secondary sludge, and food waste in batch anaerobic mono-digestion tests, and investigated the effects of mixture ratio of those organic wastes on methane yield and production rate in batch anaerobic co-digestion tests, that were designed based on a simplex mixture design method. The BMP of primary sludge, secondary sludge and food waste were determined as 234.2, 172.7, and 379.1 mL CH₄/g COD, respectively. The relationships between the mixing ratio of those organic wastes with methane yield and methane production rate were successfully expressed in special cubic models. Both methane yield and methane production rate were estimated as higher when the mixture ratio of food waste was higher. At a mixing ratio of 0.5 and 0.5 for primary sludge and food waste, the methane yield of 297.9 mL CH₄/g COD was expected; this was 19.4% higher than that obtained at a mixing ratio of 0.3333, 0.3333 and 0.3333 for primary sludge, secondary sludge, and food waste (249.5 mL CH₄/g COD). These findings could be useful when designing field-scale anaerobic digersters for mono- and co-digestion of sewage sludges and food waste.

Objectives: A restrospective chart review were conducted to investigate the overall weight loss effect of the integrated Korean medicine treatment on obese patients (body mass index [BMI] ≥25 kg/m²) in Korean medicine clinic and analyze the difference in the effect according to lifestyle behaviors. Methods: The medical records of 43 obese patients were retrospectively analyzed including body weight, BMI, waist circumference, hip circumference, and body composition who received integrated Korean medicine treatment for 4 weeks at 24 Korean medicine clinics in Daejeon metropolitan city. All outcome measures were evaluated again 8 weeks after the end of treatment at week 12 for follow-up. EuroQol-5D (EQ-5D), the Korean version of the obesity-related quality of life scale (KOQOL) and patient's satisfaction were also evaluated. The analysis was divided according to the treatment period and observation period, and subgroup analysis was performed according to drinking and exercise habits. Results: Body weight, body fat, waist circumference, hip circumference, body fat were significantly reduced at week 4 and week 12. Theses weight reduction effects were significantly greater within treatment period (0 to 4 week) than observation period (4 to 12 week). Especially in the non-exercise group, the changes in body fat mass and body fat percent showed a significant difference between the treatment period and the observation period. KOQOL were also significantly improved at 12 week, but not in EQ-5D. No severe adverse events were observed. Conclusions: The integrated Korean medicine treatment could be effective to treat obesity including weight loss. It is necessary to prevent additional weight regain through regular exercise even after Korean medicine treatment.
