Objectives: This retrospective study attempted to determine whether the treatment effect improves as the longer the medication for obese patients, also, analyzed whether the long medication increases the burden on liver function. Methods: The subjects were 278 overweight and obese female patients who took the herbal medicine Jibangsayak (JBSY) for more than 15 days. The correlation between the duration of medication and the treatment effect was confirmed, and the correlation with the safety was also analyzed. Results: JBSY significantly reduced all obesity-related measures after treatment. All these valuables before treatment were not factors in determining the duration of medication. As the duration increased, the body mass index (BMI) improvement decreased and lean body and muscle mass increased. As the duration was closer to 60 days, BMI improvement increased, and in more than 90 days group, the BMI and body fat percentage improvement stagnated as the duration longer. Aspartate aminotransferase (AST), alanine aminotransferase, and gamma-glutamyl transferase decreased after treatment. Additionally, AST decreased as the duration increased. Conclusions: This result suggests that not only the high obesity-related measures at first visit not lengthen the duration of JBSY medication. And liver function levels did not worsen as the duration increased. This result is different from the general perception that the longer the duration of medication, the greater the burden on patient's drug metabolism. However, the fact that other factors that could affect liver function could not be excluded and that kidney function evaluation should have been performed simultaneously are limitations of this study and require more detailed research in the future.

Background: A transforaminal epidural steroid injection (TFESI) is one of the methods for the conservative treatment of the lumbar spinal stenosis. As efforts to prolong the therapeutic duration and to predict the outcome of TFESI are very important, we analyzed factors considered to be associated with the therapeutic duration of a TFESI. Methods: Between August 2006 and March 2007, 69 patients (Group A: patients with no pain relief, Group B: patients with pain relief of less than 6 months, Group C: patients with pain relief of more than 6 months) who failed to the medical treatment were included to undertake a fluoroscopic-guided TFESI. Prior to treatment, the VAS (visual analogue scale), ODI (Oswestry disability index), BDI (Beck depression inventory), and BAI (Beck anxiety inventory) scores were determined to evaluate the degree of pain, disability, and psychological status. The VAS and ODI scores were used to assess the degree of pain relief. To identify the total duration of pain relief, regular outpatient visits for six months were conducted, and for the patients who were not able to visit the outpatient clinic regularly, outcome was assessed by telephone interviews after six months. Results: The dural sac cross-sectional area (DSCSA), ODI, pain duration, BDI, BAI, and age showed similar distribution for patients in the A, B, and C groups. Conclusions: The DSCSA, ODI, pain duration, BDI, BAI, and age were not associated with the therapeutic duration of TFESI in lumbar spinal stenosis patients.

Objectives: The purpose of this pilot study was to examine the feasibility of recruiting women into a clinical trial designed to examine the effects of acupuncture and electroacupuncture in treating overactive bladder (OAB) in menopause women. We tried to determine if there was preliminary evidence to suggest that acupuncture may be effective in reducing OAB symptoms and improving disease-specific quality of life. We also tried to determine the appropriate treatment duration of OAB, with safety of performing acupuncture and electroacupuncture treatment. Methods: This study was a randomized clinical trial. 7 menopause women were randomly assigned to a electroacupuncture group (EA group) (n=4) or acupuncture group (AC group) (n=3) and received electroacupuncture or acupuncture treatment twice a week (16 sessions) in 8 weeks, and follow up assessment was performed after the end of treatment. Overactive Bladder Symptom Score (OABSS), 3-day bladder diary, and King's Health Questionnaire (KHQ) were performed 4 times (at baseline (visit 0), the middle of treatment (visit 8), after the end of treatment (visit 16), and at 4 weeks of follow-up (visit 17)) and analyzed. 2 subjects were dropped out, and finally 5 subjects completed the study. Statistical analysis was performed using SPSS 18.0 for window program. Results: There was an significant improvement in night-time frequency after the treatment (visit 17) in PP (Per-protocol) group analysis (p=0.042). In additional ITT (Inter-to-treat) group analysis, the OABSS (p=0.042) and night-time frequency (p=p=0.017) were improved significantly after the treatment (visit 17). But there was no significant difference of KHQ before and after the treatment. Also there was no significant difference between EA and AC group after the treatment (visit 16, 17). Conclusions: The results of this pilot study suggested that it was feasible to recruit subjects and perform the study procedures, after reconstructing several details of study protocol in performing further clinical trial.

Background: The coronavirus disease 2019 (COVID-19) pandemic has caused significant changes. This study aimed to investigate the impact of COVID-19 on patients with chronic pain. Methods: Patients with chronic pain from 23 university hospitals in South Korea participated in this study. The anonymous survey questionnaire consisted of 25 questions regarding the following: demographic data, diagnosis, hospital visit frequency, exercise duration, time outside, sleep duration, weight change, nervousness and anxiety, depression, interest or pleasure, fatigue, daily life difficulties, and self-harm thoughts. Depression severity was evaluated using the Patient Health Questionnaire-9 (PHQ-9). Logistic regression analysis was used to investigate the relationship between increased pain and patient factors. Results: A total of 914 patients completed the survey, 35.9% of whom had decreased their number of visits to the hospital, mostly due to COVID-19. The pain level of 200 patients has worsened since the COVID-19 outbreak, which was more prominent in complex regional pain syndrome (CRPS). Noticeable post-COVID-19 changes such as exercise duration, time spent outside, sleep patterns, mood, and weight affected patients with chronic pain. Depression severity was more significant in patients with CRPS. The total PHQ-9 average score of patients with CRPS was 15.5, corresponding to major depressive orders. The patients' decreased exercise duration, decreased sleep duration, and increased depression were significantly associated with increased pain. Conclusions: COVID-19 has caused several changes in patients with chronic pain. During the pandemic, decreased exercise and sleep duration and increased depression were associated with patients' increasing pain.

This study was conducted to investigate the possible installation of small hydro-power plant at the discharge point of Gumi sewage treatment plant (STP) using treated wastewater. Sufficient amount of water to transfer to electric power and the selection of proper location are two essential elements for the construction of small hydro-power facility. Preliminary analysis based on site visit and existing data in Gumi STP were made. Capacity of the small hydro-power plants and exact location were determined by geomorphological condition and flow duration characteristics. Flow duration characteristics and its duration curve were identified using monthly rainfall data in Gumi STP. Relevant facts of small hydro-power system in other STP were referred to adopt to Gumi STP situation. Flowrate of treated effluents and effective head between flow chamber and the location of hydraulic turbine in Gumi STP are found to be $3.70m^3$/sec and 3.5m respectively. Electric generation rate based on this feasibility study was estimated to be 86.3kW/h. Yearly electric generation rate was expected to be 932.4MMh. Proposed small hydro-power plant construction in Gumi STP is to be reasonable.

Purpose: Febrile urinary tract infection (UTI) is one of the commonest bacterial infections in children. The purpose of this study is to investigate the clinical characteristics of the first episode of febrile UTI occurring in children over 5 years compared to those in infants younger than a year. Methods: We retrospectively reviewed the medical records of 10 patients over 5 years, having febrile UTI, and 25 controls under 1 year. Clinical characteristics including symptoms at admission, the time interval between symptom onset and hospital visit and/or diagnosis, duration of fever, urinalysis, and other laboratory and imaging test results were compared between the two groups. Results: Most patients in the control group showed only high fever at the time of presentation to the hospital. However, 60% of the case group had fever along with gastrointestinal (GI) symptoms such as abdominal and flank pain, vomiting, as well as relatively mild pyuria. The case group showed a longer duration between symptom onset and hospital visit and/or diagnosis. Conclusions: Delay in diagnosis and initiation of treatment of UTI increases the risk of permanent renal scarring and associated complications. Therefore, early diagnosis and treatment of febrile UTI is vital for very young infants, as well as children considering that febrile UTI could be an important cause of febrile illness in children over 5 years.
