본 연구에서는 사면위험도의 합리적인 평가 가중치를 도출하기 위하여 국내의 대표적인 평가방법에 대해 동일한 영향성을 주는 것으로 간주되는 항목들을 그룹화하여 그 영향성을 분석하고 이를 국립방재연구소(NIDP) 평가법과 비교, 사면붕괴 주요인자 선별의 적정성과 배점비율을 검토하였다. 또한, 붕괴가 발생된 28개소 사면을 대상으로 ANN(Artificial Neural Network) 기법을 적용하여 사면붕괴 유발인자 가중치에 대한 합리적 배점이 이루어졌는지에 대해 고찰하였다. ANN기법에 의해 평가비중을 재조정하여 분석한 결과, 국립방재연구소 평가법의 평가비중 오차가 큰 예상피해도, 인장균열, 계곡부 항목의 가중치를 조정하여야 보다 정확한 평가가 가능할 것으로 분석되었다.

Objectives Through this study, we investigated the effects of Korean medicine treatments on range of motion recovery and pain reduction in patients with Frozen shoulder. Methods In this study, the medical records of 26 patients diagnosed with frozen shoulder were retrospectively observed and analyzed through the IBM SPSS Statistics 25 program. We used range of motion to observe the patient's motion recovery and numeric rating scale to evaluate pain reduction. Results The shoulder range of motion increased statistically significantly from 160.0 (123.5~170.0) to 170.0 (160.0~180.0) (flexion), 115.0 (90.0~135.0) to 167.5 (130.0~178.8) (abduction), 40.8±22.1 to 58.3±16.0 (external rotation) (p<0.001). The average of numeric rating scale reduced statistically significantly from 6.7±2.0 to 3.2±1.4 (p<0.001). Depending on the period, the range of motion increased statistically significantly when visited within 3 months, also the pain score decreased 7.0 (5.4~8.0) to 3.0 (1.8~3.6) statistically significantly when visited within 3 months. In the treatment intervention, the increase in the range of motion and the decrease in pain were statistically significant, especially when the bee venom acupuncture and chuna manaul therapy were used together. Conclusions Korean medicine treatments was effective in improving the range of motion and reducing pain in frozen shoulders. In particular, when treated within 3 months of onset and when bee venom acupuncture and chuna manual therapy were used together, it was effective in recovering the range of motion and reducing pain.

Purpose: Nefopam is a centrally acting non-narcotic analgesic that has mostly been used for postoperative pain. We examined the efficacy of nefopam analgesia (alone and in combination with ketorolac) for trauma patients in the emergency department. Methods: We performed a retrospective chart review to select trauma patients who received nefopam at the emergency department of Korea University Medical Center Guro Hospital between January 2012 and December 2012. Patients younger than 15 years were excluded. The primary outcome measure was change of pain score (numeric rating scale) from baseline (before medication) to 30 min after medication. The secondary outcome measure was requirement for additional analgesia (pethidine). Results: Records of 1465 trauma patients who received analgesics in the emergency department from January 2012 to December 2012 were examined. Patients were classified into five groups according to initial analgesic: nefopam (n=112), ketorolac (n=867), pethidine (n=365), nefopam+ketorolac (92), and nefopam+pethidine (22). There were no significant differences in pain score reductions among the five groups. Twenty-two patients in the nefopam group, 141 in the ketorolac group, and 29 in the nefopam+ketorolac group required rescue analgesia with pethidine; these rates were not significantly different. Conclusion: The efficacy of nefopam analgesia for trauma patients in the emergency department is comparable to that of more commonly used agents, including ketorolac and pethidine.

With the phaseout of CFC and HCFC refrigerants, refrigeration and heat pump systems must be redesigned to match and improve system performance with alternative refrigerants. A generalized flow model for predicting mass flow rate through short tube orifices is derived from a power law form of dimensionless parameters generated by Pi-theorem. The database for developing the correlation includes extensive experimental data for R12, R22, R134a, R407C, R410A, and R502 from the open literature. The correlation yields an average deviation of $0.3\%$ and a standard deviation of $6.1\%$ based on the present database. In addition, rating charts for predicting refrigerant flow rate through short tube orifices are generated for R12, R22, R134a, R407C, R410A, and R502.

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.
