Purpose: The aim of this study was to determine whether there is a correlation between the type and stability of intertrochanteric fractures caused by low-energy trauma and gluteus muscle volume. Materials and Methods: A total of 205 elderly (>65 years) patients with intertrochanteric fractures caused by low-energy trauma treated from January 2018 to December 2020 were included in this study. The mean age of patients was 81.24 years (range, 65-100 years). Fractures were classified according to the Jensen modification of the Evans classification. The cross-sectional area of the contralateral gluteus muscle (minimus, medius, and maximus) was measured in preoperative axial computed tomography slices. An analysis and comparison of age, body mass index (BMI), weight, height, and the gluteus muscle area in each fracture type group was performed. Results: In the uni-variable analysis, statistically significant taller height was observed in patients in the stable intertrochanteric fracture (modified Evans 1 and 2) group compared with those in the unstable intertrochanteric fracture (modified Evans 3, 4, and 5) group (P<0.05). In addition, significantly higher BMI-adjusted gluteus muscle area (gluteus muscle area/BMI) was observed for the stable intertrochanteric fracture group compared with the unstable intertrochanteric fracture group except for the BMI-adjusted gluteus minimus area (P=0.112). In multivariable analysis, only the BMI-adjusted gluteus maximus (P=0.042) and total gluteus areas (P=0.035) were significantly higher in the stable group. Conclusion: Gluteal muscularity around the hip, especially the gluteus maximus, had a significant effect on the stability of intertrochanteric fractures.

목적: WHO의 통증관리원칙에 따른 통증관리의 효과가 입증되었으며 불충분한 통증관리의 문제점을 해결하려는 많은 노력이 있어 왔다. 본 연구는 말기암환자들의 통증정도와 불충분한 통증관리에 영향을 미치는 환자의 특성을 밝히고자 하였다. 방법: 1997년 6월부터 1997년 11월까지 서울대학교병원에서 말기암으로 판정받은 성인 암환자 100명을 대상으로 활동도, 전이여부 등을 포함한 인구 의학적 특성과, 사용되고 있는 진통제를 보정한 통증정도를 조사하였다. WHO의 통증관리지침에 따라 통증관리의 적절성을 평가하였으며 이에 영향을 미치는 환자의 특성을 조사하였다. 결과: 말기암판정당시 85%의 환자들이 통증이 있었으며 65%의 환자들이 중등도이상의 통증을 갖고 있었다. 말기암환자 38%가 불충분한 통증관리를 받고 있었으며 통증의 정도가 심할수록 불충분한 통증관리를 받고 있었다(P<0.001). 성별 연령, 암의 원발부위, 전이여부, 우울 및 불안 증상, 활동도는 통계적 유의성이 없었다. 결론: 통증관리지침이 제시되었음에도 불구하고 많은 말기암환자들이 충분한 통증관리를 받지 못하고 있다. 이를 해결하기 위해서 통증 평가방법과 통증관리지침에 관한 적극적인 교육 및 훈련이 필요하다.

Background & Objectives: There were increasing evidence about the relationship between allergy related disease such as asthma, atopic dermatitis and allergic rhinitis and suicide ideation. However little was known about the concrete relatedness between severity and comorbidity of allergy related disease with suicide ideation. The objective of this study was to investigate the cases of the prevalence of suicide ideation among adolescents with allergy related disease such as asthma, atopic dermatitis and allergic rhinitis, and examine the association between allergy related disease and suicidal ideation among adolescents in South Korea. Methods: Data was based on Korean Youth Risk Behavior Web-based Survey(2014) which was a cross-sectional study containing 34,874 Korean middle and high school students who diagnosed with allergy related disease. We used the weights, strata and primary sampling unit information provided by the public use dataset to compute descriptive statistics and logistic regressions. Computations were done with SPSS version 20.0. Results: 19.9%, 15.6%, 13.8% of adolescents who suffered from one, two and three of allergy related diseases respectively reported having been thought of suicide ideation. Socio-demographic factors were adjusted as control variables. Students with greater severity of disease were more likely to have suicide ideation. Odds ratio for students who were absent one to three days from school because of allergies was 1.96(95% CI 1.51-2.46), and odds ratio for those who were absent more than four days from school was 3.60(95% CI 2.46-5.28). Conclusions: Given that adolescents' severity and comorbidity of allergy related disease were clearly associated with suicide ideation, suicide prevention programs for adolescents with allergy related disease should be improved by strategic approaches towards the severity and comorbidity of disease.

Preoperative and postoperative psychiatric evaluation were done for 51 patients who were undergoing open-heart surgery. The incidence of postoperative psychopathological complications following open-heart surgery was 27.5%. This rate is comparable to that of previous studies. Neurotic reactions occurred in eight patients, delirium in five, and acute psychotic reaction in one. Of those variables which were previously suggested to influence the high incidence, the demographic factors and the severity of preoperative illness were correlated with postoperative psychopathologic dysfunctions. No somatic variable associated with intraoperative or postoperative procedures has been proven to correlate. By preoperative psychiatric evaluations, the patients could be divided into three groups: the Anxiety group, the Denial group, and the Adjusted group. The most important psychological finding was that in patients who demonstrated a high degree of preoperative anxiety or who could not express preoperative anxiety, postoperative psychological complications developed more frequently. With these findings, the preoperative psychiatric interview was recommended for prevention and reduction of postoperative psychiatric complications.

In this paper, the variability of modal properties caused by temperature effects is assessed to adjust modal data used for frequency-based damage detection in plate-girder bridges. First, experiments on model plate-girder bridges are described. Next, the relationship between temperature and natural frequencies is assessed and a set of empirical frequency-correction formula are analyzed for the test structure. Finally, a frequency-eased method is used to locate and estimate severity of damage in the test structure using experimental modal data which are adjusted by the frequency-correction formula. Here, local damage in beam-type structures is detected by using measured frequencies and analytical mode shapes.

New materials are very useful due to their wide range of applications, however, they also have caused new pollutants that damage our environment. Chemists have been conscious of the severity of these environmental problems and a great deal of effort has been put into developing environmentally benign chemical processes to synthesize new materials (green synthesis). We also have reported a green synthesis method of synthesizing silver nanoparticles using water-glycerol solution in a previous study. While conducting further research, we have recently discovered that the size of silver nanoparticles is proportional to the quantity of water present in glycerol. This method is completely benign and ecofriendly pathway, as the size of silver nanoparticles is adjusted solely by controlling the quantity of water added to glycerol, without extra additives and energy.

Purpose: To evaluate the severity of trauma, many scoring systems and predictive models have been presented. The quick Sequential Organ Failure Assessment (qSOFA) is a simple scoring system based on vital signs, and we expect it to be easier to apply to trauma patients than other trauma assessment tools. Methods: This study was a cross-sectional study of trauma patients who visited the emergency department of Jeju National University Hospital. We excluded patients under the age of 18 years and unknown outcomes. We calculated the qSOFA, the Modified Early Warning Score (mEWS), Revised Trauma Score (RTS), and Injury Severity Score (ISS) based on patients' initial vital signs and assessments performed in the emergency department (ED). The primary outcome was mortality within 14 days of trauma. We analyzed qSOFA scores using multivariate logistic regression analysis and compared the predictive accuracy of these scoring systems using the area under the receiver operating characteristic curve (AUROC). Results: In total, 27,764 patients were analyzed. In the multivariate logistic regression analysis of the qSOFA, the adjusted odds ratios with 95% confidence interval (CI) for mortality relative to a qSOFA score of 0 were 27.82 (13.63-56.79) for a qSOFA score of 1, 373.31 (183.47-759.57) for a qSOFA score of 2, and 494.07 (143.75-1698.15) for a qSOFA score of 3. In the receiver operating characteristic (ROC) curve analysis for the qSOFA, mEWS, ISS, and RTS in predicting the outcomes, for mortality, the AUROC for the qSOFA (AUROC [95% CI]; 0.912 [0.871-0.952]) was significantly greater than those for the ISS (0.700 [0.608-0.793]) and RTS (0.160 [0.108-0.211]). Conclusions: The qSOFA was useful for predicting the prognosis of trauma patients evaluated in the ED.
