Introduction: The purpose of this study was to combine the two methods of Tripod beta and SCAT to analyze the accidents, explain their leading details, and track the roots of events at the depth of organizational layers.Methods: This analytical-descriptive study was carried out in one of the steel companies in Iran. To conduct the study, we analyzed one of the death- leading events using the combination of SCAT and Tripod methods. We investigated the relationship between variables and analyzed the intermediate and root causes of the event by Tripod beta method.  Moreover, we proposed some control measures in the SCAT cause and effect table. The information achieved from the questionnaire and effects of the accidents' causes were studied and rated using the chi-square test and Friedman test, respectively.Results: The most important direct cause of the accident was "removal of bucket wheel (in the Boom Claimer device) from the shaft". The most important intermediary cause of the event was "lack of an appropriate immune system at the time of balance weight release". The most important rudimentary cause of the event was "inappropriate location of the device cabin in the original design". Furthermore, the most important control measure was “using harvesting equipment with new design".Conclusion: According to the statistical tests, we found a systematic connection between root causes and intermediate causes of the incident. Moreover, we observed that the effect of root causes and intermediary causes were not similar regarding the accident.

Abstract Background: The novel virus (COVID-19) pandemic threats the global most since the World War II yet difficult to design effective policy to respond it because widely utilized models only support to predict the future tendency within a narrow time-window. Besides, existing pandemic metrics are sensitive to the detecting policy ( p <0.001), which make them hard to reveal the real infection phenomena, because the fluctuation of these metric values may be an outcome of a suddenly changed detecting policy instead of real infection increase or decrease. Methods: We developed a Benchmark, Amendment and Validation model (BAVM) to make the above complex phenomena clearer, and combined with the hypothesis of potential periodicity of COVID-19 to devote jointly the retreated prediction of pandemic within a broad time-window. Onward, we utilized 113 countries’ epidemic data from January 21, 2020 to August 31, 2020 and detecting policies to carry out our methodology, then validated the results through statistical tests involving chi -square test, one t-test and independent t test. Results: Results exhibit the 4-month of potential periodicity between two adjacent peaks of pandemic ( t =–1.56, p =12.4%). Besides, whether or not the peak emergence has no effect on COVID-19 dynamic trajectory, but the time to firstly peak affects. Meanwhile, uprising the quarantine rate exhibits the earlier expedition towards the first peak emergence (9.7% vs. 6.2%, p =4.1%). On the contrary, the delay of first peak increased the infection rate (0.6% vs. 0.3%, p =1.5%) but also the discharge rate (65% vs. 74%, p =3.8%). Moreover, the indication of the retreated tendency of COVID-19 pandemic is that the next peak should emerge but in fact vanished after one periodicity. Otherwise, the pandemic enters into the next worse phase, typical of high mortality (5% vs. 3.4%, p =5.3%) and low discharge rate (65.8% vs. 74.1%, p =4.2%). Conclusion: To recognize the retreated tendency of this pandemic is quite significant for either the global or the local policy-making, especially in the regular epidemic prevention, control measures and work resumption.

Background: Tuberculosis (TB) and diabetes mellitus (DM) prevalence rates are increasing rapidly, especially in developing countries like Indonesia. There is a relationship between TB and DM that are very prominent, which is the prevalence of pulmonary TB with DM increased by 20 times compared with pulmonary TB without diabetes. Chest X-ray picture of TB patients with DM is atypical lesion. However, there are contradictories of pulmonary TB lesion on chest radiograph of DM patients. Nutritional status has a close relationship with the morbidity of DM, as well as TB.Objectives: The purpose of this study was to determine the relationship between the lesions of TB on the chest radiograph of patients who su?er from DM with their Body Mass Index (BMI) in Hasan Sadikin Hospital Bandung.Material and Methods: The study was conducted in Department of Radiology RSHS Bandung between October 2014 - February 2015. We did a consecutive sampling of chest radiograph and IMT of DM patients with clinical diagnosis of TB, then the data was analysed by Chi Square test to determine the relationship between degree of lesions on chest radiograph of pulmonary TB on patients who have DM with their BMI.Results: The results showed that adult patients with active pulmonary TB with DM mostly in the range of age 51-70 years old, equal to 62.22%, with the highest gender in men, equal to 60%. Chest radiograph of TB in patients with DM are mostly seen in people who are obese, which is 40% and the vast majority of lesions are minimal lesions that is equal to 40%.Conclusions: There is a signifcant association between pulmonary TB lesion degree with BMI, with p = 0.03

Implementation of IMD in hospitals has decreased from the previous year and has not reached the target set by the government. Some IMD implementation processes have not been carried out according to applicable standards. So that babies do not get an IMD in accordance with existing SOPs. The purpose of this study was to determine the determinant factors associated with the implementation of the IMD by midwives in the Midwifery and Maternity Room Emergency Room (IGD) at the Anutapura General Hospital in Palu. This research method is analytical with cross sectional approach. The population of this study was that all midwives in the obstetrics emergency room and maternity room at Anutapura Palu Hospital were 37 respondents. The sample in this study is total sampling. The analysis used was univariate, and bivariate analysis using the chi square test with a confidence level of 95% (α = 0.05). The results of statistical tests on variable knowledge of midwives with the implementation of IMD p value: 0.018 (p value <0.05). APN training with the implementation of IMD p value: 0.697 (p value> 0.05). length of work with the implementation of IMD p value: 0.029 (p value <0.05). and peer support with the implementation of IMD p value: 0.007 (p value <0.05). Conclusions there is a relationship between knowledge, length of work, peer support with the implementation of the IMD, and training factors that have nothing to do with IMD implementation. The strongest factor in the relationship is peer support. It is recommended that the Anutarapura Palu Hospital be able to motivate midwives so that they can further enhance their role in the implementation and provide support to their colleagues so that the implementation of the IMD can be carried out in accordance with applicable standards.Keywords: Knowledge, APN Training, Duration of work, Implementation of IMD

489 Background: Immune checkpoint inhibition (ICI) has greatly improved clinical outcomes for pts with mUC and other cancers. ICI is associated with a class of AEs, deemed irAEs due to immune activation. Nonetheless, biomarkers associated with irAE are still lacking. We hypothesized that the immune response against neoantigens is partly responsible for irAEs and investigated the association between irAEs, TMB and response to ICI. Methods: We identified patients with mUC at Dana Farber Cancer Institute who were treated with ICI (monotherapy or combination) and had available tumor sequencing data through Oncopanel. TMB was calculated using the number of non-synonymous exonic mutations per megabase. The severity of irAEs was graded using CTCAE v.5.0. Mann-Whitney U test was performed to identify association between TMB, incidence and grade of irAEs. A cut-off of 10/mb was assigned for TMB. Fisher’s exact test was used to evaluate the radiologic response between pts with and without irAEs and low vs. high TMB. Multivariable linear regression was used to assess the relationship between TMB, irAEs and response. p-values were adjusted using Benjamini-Hochberg method. Results: Of 101 pts with mUC who met the inclusion criteria, 32 (32%) reported irAEs. 6 (6%) were grade (G)1, 20 (20%) were G2, and 6 (6%) were G3. Median(m) time on therapy was 84 days for pts without irAEs and 88 days for pts with irAEs. Pts with irAEs had higher mTMB (15.4/mb) compared to pts with no irAEs (9.8) ( p = 0.01). In pts on monotherapy (93), those with irAEs (n=27) had a higher mTMB (15.13/mb) compared to pts with no irAEs (n=66) (mTMB = 10.20/mb) ( p = 0.01). Out of 94 pts with radiological data, response was achieved in 16 (50%) pts with irAE vs 10 (16%) pts with no irAE ( p < 0.001). When both irAE and response were included in a multivariable regression, the association between irAE and TMB was not significant ( p = 0.4). Pts with both irAE and high TMB had a response rate of 56% which was significantly higher than those with either irAE but low TMB (28.6%) or high TMB but no irAE (21.2 %) or low TMB and no irAE (10.3%) (Chi-square test p = 0.002; FDR corrected p-values for individual comparisons in Table). There was no association between TMB and irAE grade. Conclusions: Higher TMB was associated with higher incidence of irAEs in pts with mUC on ICIs. Moreover, pts with both high TMB and irAEs exhibited better response rates than those with only high TMB or irAEs, suggesting that they may provide complementary tumor and host characteristics. Further evaluation in mUC is needed to confirm this relationship between TMB, irAEs and response in a larger cohort and explore specific mutational signatures that may be associated with irAEs.
