Objectives: This study aimed to compare the quality of life reported by patients with attention-deficit/hyperactivity disorder (ADHD) to the patients' quality of life as reported by their caregivers. In addition, it aimed to examine how emotional problems, including depression and anxiety, and the severity of the symptoms affect the quality of life reported by the patients and their caregivers. Methods: The patients' quality of life and their degree of depression and anxiety were measured using the Pediatric Quality of Life Inventory (PedsQL) 4.0 Child Self-Report, the Children's Depression Inventory (CDI), and the Revised Children's Manifest Anxiety Scale, respectively. The caregivers' perception of the patients' quality of life and severity of the ADHD symptoms were measured using the PedsQL 4.0 Parent Proxy Report and the Conners' Parent Rating Scale (CPRS), respectively. A total of 66 participants completed the survey. The independent-samples t-test, Pearson's correlation analysis, and multiple regression analysis were conducted. Results: The mean score of the PedsQL 4.0 Child Self-Report was significantly higher than the mean score of the PedsQL 4.0 Parent Proxy Report. However, for school function, the PedsQL 4.0 Child Self-Report score was significantly lower than that of Parent Proxy Report. The correlation between the PedsQL 4.0 Child Self-Report and PedsQL 4.0 Parent Proxy Report scores was significant only for emotional function and social function. The multiple regression analysis showed that the PedsQL 4.0 Child Self-Report and PedsQL 4.0 Parent Proxy Report scores were significantly predicted by the CDI and CPRS scores, respectively. Conclusion: Our results demonstrate that there are clear differences between the quality of life reported by the patient themselves and that reported by their caregivers. In addition, the findings suggest that it is critical to treat the patients' accompanying depressive symptoms.

As the LNG storage tank is aged, if there is a crack in the outer wall concrete or corrosion of the reinforcing steel, there is a risk of a major accident such as collapse of the structure depending on the type and degree of damage. Since 2014, LNG storage tanks have undergone precise safety diagnosis and safety inspection has been carried out. The condition evaluation criteria for each component have been revised and applied in January 2016. The condition evaluation standard is to evaluate the status of storage tanks based on the appearance survey and material test results of LNG storage tanks and it is important for maintenance. In addition, the representative condition evaluation standard that shows the comprehensive state of each LNG storage tank is important in maintenance, but the related standard for LNG storage tank outer concrete is not available in Korea and abroad, and development of the condition evaluation standard is necessary. In this paper, we examined the structural characteristics of LNG storage tanks, analyzed the status of the condition evaluation criteria for each member, and developed a comprehensive status rating system by weighting the members. We used the AHP(Analytic Hierarchy Process) technique and developed a representative conditon evaluation criteria through surveys of professional organizations.

Archives should provide a web-based archival information service with good usability based on the understanding of users' needs. Thus, this study analyzed the usability of the National Archives of Korea (NAK) website's search service through expert and usability evaluations for various users and suggested improvement plans. A literature review, heuristic evaluation, one of the usability expert evaluation methods, and usability evaluation for users were performed. As a result of expert evaluation, the severity rating for the usability problem was highest regarding a match between the system and real world and the lowest in error prevention. In the usability evaluation, it was assumed that the user's background and whether the website's help was provided is associated with usability. Usability evaluation was conducted for 22 participants, including those majoring in records management, web/application developers, and people without such backgrounds. Furthermore, a presurvey, a five-second test, and search tasks were conducted in a row. The analysis based on usability components in ISO 9241-11: 2018, i.e., effectiveness, efficiency, and satisfaction, showed that web/application developers had the highest search effectiveness, and those majoring in records management showed high effectiveness only in the search for archival content services. Background factors did not affect efficiency, and the more familiar with the finding aids, the better the efficiency. Moreover, providing the website's help was found to be positively associated with effectiveness and satisfaction. This study suggests that the NAK website will offer a user-friendly interface and search function, expand help support, and display a consistent web interface.

Continuous and accurate instrument of river water usage is needed for sustainable river water management. Although the instrument methods applicable to each point of use of river water are different, more precise direct instrument methods are required at the point of major open channel. Users of river water should select appropriate direct instrument methods to measure usage, but there is a lack of standards and verification research. In this study, the H-Q rating curve method, ultrasonic method, and microwave method were applied directly to the test basin in the upper basin of Mangyeong river, and the accuracy of measurement data was evaluated by comparing absolute error between discharge data calculated by instrument method. When comparing the calculated discharge of point units, the ultrasonic method showed the best results of the actual measurement. Through continuous instrument, the sum of the daily and monthly units was compared, and the ultrasonic and microwave methods were shown to be highly accurate. Based on the results of this study, it is hoped that the appropriate direct measurement method can be selected according to the importance of the river water use facility, considering that the ultrasonic method and the microwave method are relatively costly compared to the water level-flow relationship method.

This study investigated the fire risk assessment of woods and plastics for construction materials, focusing on the fire performance index-III (FPI-III), fire growth index-III (FGI-III), and fire risk index-IV (FRI-IV) by a newly designed method. Japanese cedar, red pine, polymethylmethacrylate (PMMA), and polyvinyl chloride (PVC) were used as test pieces. Fire characteristics of the materials were investigated using a cone calorimeter (ISO 5660-1) equipment. The fire performance index-III measured after the combustion reaction was found to be 1.0 to 15.0 with respect to PMMA. Fire risk by fire performance index-III increased in the order of PVC, red pine, Japanese cedar, and PMMA. The fire growth index-III was found to be 0.5 to 3.3 based on PMMA. Fire risk by fire growth index-III increased in the order of PVC, PMMA, red pine, and Japanese cedar. COpeak concentrations of all specimens were measured between 106 and 570 ppm. In conclusion, it is understood that Japanese cedar with a low bulk density and PMMA containing a large amount of volatile organic substances have a low fire performance index-III and high fire growth index-III, and thus have high fire risk due to fire. This was consistent with the fire risk index-IV.

Objective : Although radiotherapy (RT) is recommended for multiple myeloma (MM) involving spine, the treatment of choice between reconstructive surgery with RT and RT alone for pathologic vertebral fractures (PVFs) associated with structural instability or neurologic compromises remains controversial. The purpose of this study was to evaluate the clinical efficacies of reconstructive surgery with adjuvant RT for treatment of MM with PVFs by comparing with matched cohorts treated with RT alone. Methods : Twenty-eight patients underwent reconstructive surgery followed by RT between 2008 and 2015 in a single institution, for management of PVFs associated with structural instability of the spine and/or neurologic compromises (group I). Twenty-eight patients were treated with RT alone (group II) after propensity score matching in a 1-to-1 format based on instability of the spine, as well as age and performance. Clinical outcomes including the overall survival rates, duration of independent ambulation, neurological status, and numeric rating scale (NRS) for back pain were compared. Results : Clinical and radiological features before treatment were similar in both groups. The median survival period was similar between the two groups. However, the mean duration of independent ambulation was significantly longer in group I (88.8 months; 95% confidence interval [CI], 66.0-111.5) than in group II (39.4 months; 95% CI, 25.2-53.6) (log rank test; p=0.022). Deterioration of Frankel grade (21.4% vs. 60.7%, p=0.024) and NRS for back pain (2.7±2.2 vs. 5.0±2.7, p=0.000) at the last follow-up were higher in the group II. Treatment-related complications were similar in both groups. Conclusion : In patients with unstable PVFs due to MM, reconstructive surgery may yield superior clinical outcomes compared with RT alone in maintaining independent ambulation and neurological status, as well as pain control despite similar median survival and complications.

Objectives This study was conducted to evaluate the clinical efficacy and safety of the chuna combination treatment for patients who complain of functional impairment and pain even 3 months after total knee arthroplasty. Methods 24 patients who had 3 months of surgery and who had knee joint pain with a score of 4 or higher on the numerical rating scale (NRS) for more than a week were selected as subjects. The test group received usual care and Chuna treatment and the control group received the administration of drugs as usual care. And then the clinical efficacy and safety were compared and evaluated. Follow-up was performed 1 month after the end of treatment. Results As a result of the analysis, it was confirmed that the primary parameter Korean Western Ontario and McMaster Universities (K-WOMAC) showed statistical significance in the amount of change in visit 2-visit 10 (V2-V10) in the pain domain and in the amount of change in visit 2-follow 1 (V2-FU1) in the functional domain and total score domain. The secondary parameter (NRS, risk of fall, and range of motion) showed a tendency to decrease in the degree of discomfort, but statistical significance could not be confirmed. Conclusions Because this study did not have enough study subjects, it is difficult to use the results as confirmatory evidence. However, it was confirmed that the 4-week Chuna treatment had a significant effect and safety in patients who underwent total knee arthroplasty. Therefore, this study is meaningful as a prior research data to prepare confirmatory evidence in the future.

Purpose: Symptoms of idiopathic Parkinson's disease (PD) include tremors, bradykinesia, and rigidity. The purpose was to explore the effects of breathing, meditation and qigong on the improving of insight, behavior, mood discomfort, depression, anxiety, and olfactory dysfunction, which are PD non-motor symptoms. Methods: Three stages of An's-4444 healing breathing, An's Gwanjeong healing meditation, and healing qigong performed 12 times for 80 minutes at a time in subjects with PD (11 patients), and pre- and post-measurements compared and evaluated. Results: The Integrated Parkinson's Rating Scale (UPDRSI) for mood discomfort after 12 healings was 69%. The Depression Scale (61%) for HAMD, and 64% for Anxiety (HAMA)), and the smell identification test (TSI) for a trial for olfactory dysfunction, improved to 82%, respectively. However, the numerical values after one month after 12 healing were almost same in all four scales. This means that the healing effect maintained until after one month. Conclusions: An's healing breathing, meditation and qigong therapy significantly improved insight, behavior, and mood discomfort, and non-motor symptoms such as depression, anxiety, and olfactory dysfunction. These results suggest that An's breathing, meditation and qigong therapy are valuable as a primary therapy to improve and heal non-motor symptoms in Parkinson's disease patients. Further research in biomedical science is needed.

Due to the coronavirus disease 2019 (COVID-19) pandemic, appropriate management of sequelae and treatment of infectious symptoms became increasingly important healthcare issues. Although the practice guidelines and treatment cases based on the East Asian traditional medicine have been reported, there are rare studies on the use of Korean medicine in Korea. Therefore, this study aimed to present the progress of non-contact Korean medical treatment for infected patients at a local public health center using retrospective chart review. A total of 18 patients were prescribed with 5 days of herbal decoction and medicine extract covered by the national health insurance. With the questionnaire form, the progression and improvement of symptoms before and after treatment were evaluated using the numerical rating scale (NRS), and the treatment satisfaction and opinions were obtained. The symptoms such as cough (5.56±2.23 to 2.89±2.14), sputum (6.11±1,75 to 3.28±2.47), sore throat (6.06±2.70 to 1.47±1.62), anorexia (5.56±2.63 to 1.94±2.21), nausea (3.75±1.71 to 1.17±1.11), diarrhea (3.40±2.63 to 1.50±1.51), chest tightness (4.93±2.46 to 2.29±2.30) and fatigue (6.44±1.79 to 2.67±1.88) all improved according to the NRS, and the satisfaction with herbal medicine treatment on a 5-point Likert scale was 4.24±0.90. No side effects and adverse reactions were reported. Thereupon non-contact Korean medical treatment can be concluded that it effectively reduces the COVID-19 infection mild symptoms in restrictive extent. Since the retrospective data does not include a control group, the more confirmative data is needed by multicenter and large-scale controlled clinical study afterwards.

Purpose: The purpose of this paper is to report the improvement of a patient with amyotrophic lateral sclerosis after long-term combined Korean medical treatment. Methods: A patient diagnosed with amyotrophic lateral sclerosis was treated with herbal medicine, acupuncture, pharmacopuncture, moxibustion, and rehabilitation for four separate hospital stays. To evaluate their respiratory discomfort and limb weakness, we used Manual Muscle Testing, the Pulmonary Function Test, and the Korean Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised. Results: The weakness of the muscles of the lower extremities and respiratory function was improved. Conclusion: We consider that combined Korean medicine treatments might be an effective treatment for muscle weakness and respiratory discomfort of amyotrophic lateral sclerosis. To verify the effectiveness of these treatments, further research is required.
