The Authors studied the relationship between visual fatigue (or asthenopia) and different types of work with display units on about 30,000 videoterminal (VDT) operators of the Italian telecommunication company. Visual fatigue was reported with data entry, data checking, word processing, dialogue enquiry, and various services. The Chi-square test showed that asthenopia was not related to any particular type of VDT work, comparing subjects working at the VDT for similar times each week. These findings provide further confirmation that the main factor determining visual fatigue in VDT operators is the amount of time spent at the display units.

The relationship between visual discomfort (or asthenopia) and different types of work using display units for 10,626 videodisplay terminal operators of the Italian Telecommunication Company was studied. Visual discomfort was evaluated as related to data entry, data checking, word processing, dialogue, enquiry, and various services. Chi-squared indicated that visual discomfort was not significantly related to any particular type of work for subjects with similar amounts of weekly time using videodisplay units. These findings are consistent with earlier results indicating that the main factor determining visual fatigue in VDT operators is the amount of time spent on the display units.

Adherence to hand hygiene recommendations by health care workers (HCWs) participate to minimize healthcare-associated infections. There are few studies, to our present state of knowledge, which interested in the rate of adherence in Algerian hospitals and no one on the associated factors with the non-adherence by HCWs. The objective was to determine the rate of adherence with WHO's hand hygiene recommendations and to identify factors associated with non-adherence, in a regional university hospital. The method used was the direct observation, based on the recording of hygienic actions in opportunities for HCWs in front of the WHO's five indications. To determine the factors associated with non-adherence, a questionnaire was administrated to HCWs. The relationship between the different factors and the achievement of a hygiene action was evaluated by Pearson's Chi-square test. 503 opportunities for hand hygiene were observed among 206 HCWs, during 19 observation sessions. Simple handwashing was noted in 19% of hand hygiene actions. The overall adherence was 21 %. There was a wide variation in the adherence rates between the different departments and the different types of HCWs. There was a statistically significant association (p

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

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.

The major objective of this study was to measure the association between various interventions and Chitral Gole National Park (CGNP) role in preservation of bio-diversity and socio-economic uplift. A sample size of 346 respondents was randomly selected from total population of 3326 from the 4 selected villages on the basis of close proximity. A conceptual framework including dependent variable social development and independent variable tourism development were taken. The data were analyzed through frequency and percentage distribution. Moreover, Chi-square test was applied to know the relationship between dependent and independent variables at bi-variate level. In bi-variate analysis a highly significant (P=0.000) relation was found between CGNP is main source of promoting tourism in Chitral,tourists do any impacts upon local community in terms of increased business activities, local culture is safeguarded despite influx of tourists in the area, tourism produced employment opportunities, and social development. Qualitative data supported the empirical findings, however tourism brings economic opportunities at micro and macro level, but unfortunately CGNP is not as satisfactory regarding generating income since its establishment. The government should ensure to make such polices pertaining to the entrance fee, provides accommodation services on payment to the tourists and to reserve the entrance fee or any other form of taxes to ensure CGNP to spend on self-sustaining basis by ensuring refinement in the procedures as well.

The study analyses the relationship between currency redenomination and financial sector transaction costs in Nigeria using a sample of 200 respondents from ten financial institutions. Applying the Chi-square test, the study reveals that high currency redenomination removes wasteful transactions removes user costs (difficulties arising from memorizing, calculating and carrying large sum of lowest denominations: coins and smaller notes). The results also show that currency redenomination influences inflationary pressure and currency liberalization in Nigeria. Based on the findings the study recommends the introduction of currency redenomination to facilitate the consumers' cash payment and reduce the cost incurred by producers and issuing authorities, and also make payment system more efficient and effective.

ABSTRACTFirst year student are one of the groups that are prone to depression. This is because the first year student is in a transition period or in a new condition that initially senior high school student becomes a college student. In addition, busy schedules, new learning environments and homesickness can trigger depression in college students. This study used a cross sectional study design. Respondents in this study were new students of the Study Program Outside the Main Campus (PSDKU) of Airlangga University in Banyuwangi, class 2019 with a total of 110 students. Depression levels were obtained from the Beck Depression Inventory (BDI-II) questionnaire. Meanwhile, the adaptability was obtained from the Communicative Adaptability Scale (CAS) questionnaire and the place of residence was obtained from questions about where to live during college. A total of 53 out of 110 students (49,1%) experienced low depression and students who experienced high depression were 57 out of 110 students (50,9%). The results of the chi square test regarding the relationship between residence and the level of depression of new students, obtained data p= 0.008 (p <0.05). Chi-square test results regarding the relationship between adaptation ability and depression level of new students, obtained data p = 0.001 (p <0.05). There is a relationship between residence and adaptability with the degree of depression of new students. Higher education institutions are expected to pay more attention to the psychological conditions of students and new students are expected to maintain good coping management in facing the new environment.Keywords: depression level, adaptability, place to live, new students ABSTRAKMahasiswa baru adalah salah satu kelompok yang rentan mengalami depresi.
