Authors: Reviandani Wasti 
Published: July 2023

Background - Students are part of the community who are studying higher education and are expected to be an example for other people in investing, the investment level is still low, it is necessary to improve so that the investment interest of the community, including students, can increase in the future.
Aim - The purpose of this study was to determine whether the perception of return and risk as well as the mediation of investment knowledge can influence students' investment interest.
Design / methodology / approach - The research approach is quantitative and data is obtained from distributing questionnaires which are then processed using data analysis techniques using the SEM (Structural Equation Modeling) model using the SmartPLS 3.0 (Partial Least Square) program.
Findings - Based on the results of the analysis it is proven that students' perceptions of returns and investment risks have an effect on investment intentions. Investment knowledge has a significant effect on investment knowledge, this empirical result means that the higher students understand returns and risks, and know about investment, the higher the interest in investing in students. Student investment knowledge is proven to be able to mediate the effect of perceived returns and investment risks on investment intentions. Proven student investment knowledge will have an indirect impact on student investment interest.
Conclusion - The results of this study indicate that student knowledge is one of the most important factors to increase interest in investing. The earlier we invest, the better prepared we are to face the challenges and risks that may arise in the future.
Research implications - Investment is something that students need to study in order to know the right investment and provide long-term benefits. Basically, people who invest are a sign that the person has prepared himself to face the changing economy of a country, so that by preparing himself to face things that are not desirable in the future, especially related to the economy. This research also contributes to science, especially financial management, the results of this study provide a perspective where investment interest is not focused on returns and risks, but requires knowledge about investment.
Research Limitations - This research has limitations, namely the population and sample are only focused on UMG 2019 management study program students and cannot be averaged with other objects, future researchers are expected to expand the sample with a wide coverage so that this research can be applied in general.

The microstructure and tribological characteristics of the modified surface of AISI E3310 and AISI A290C1M structural alloy steels after laser treatment using an ytterbium continuous fiber laser have been studied. Laser surface treatment was carried out on air with laser power outputs of 75 W and 100 W and scanning speeds from 2 to 14 mm/s. Metallographic analysis and durometer testing were applied to determine the structure of laser action zones and the steel structural components there. It has been shown that the scanning speed at a laser power of 100 W has the most significant effect on the dimensions of the laser action zones. The maximum depth of the laser action zone during laser treatment without surface melting is 310 and 170 µm for E3310 and A290C1M steel, respectively. Depending on the mode of hardening, the microhardness in the laser action zones varies from 1.36 to 1.97 times for E3310 steel; as for A290C1M steel, it increases by 2.0 – 2.6 times. At 100 µm hardening depth, the reduction in linear wear and wear intensity reaches 26.6 % and 43.9 % for E3310 and A290C1M steel, respectively.

Published: July 2023

Coronavirus disease 2019 (COVID-19) emerged at the end of 2019 and quickly spread worldwide. Among the various comorbidities associated with severe disease, chronic kidney disease (CKD) has been identified as one of the leading conditions. However, it is not yet clear whether all stages of CKD pose the same risk for severe COVID-19 infection. Therefore, the objective of this study was to assess the impact of different stages of CKD on the clinical characteristics, disease progression, and outcomes of COVID-19.
Methods. This retrospective study focused on CKD patients who were admitted with COVID-19. We analyzed various factors including demographic data, comorbidities, symptoms, physical findings, laboratory test results, length of hospital stay, and in-hospital outcomes. These factors were evaluated based on the different stages of CKD.
Results. A total of 284 CKD patients infected with SARS-CoV-2 were evaluated and compared to 395 COVID-19 patients with normal kidney function. Among the CKD patients, 86 were receiving dialysis. We observed significantly higher levels of C-reactive protein, procalcitonin, D-dimer, and ferritin, as well as a significantly lower lymphocyte count, in the CKD groups compared to the control group. There were significant differences among the CKD groups in terms of biochemical markers, duration of hospital stay, rates of ICU admission, and mortality. However, we did not find significant differences between dialysis and non-dialysis CKD patients regarding the length of hospital stay, need for ICU admission, and number of deceased patients.
Conclusions. The presence and severity of CKD should be considered crucial factors for predicting the risk of COVID-19. Patients with late-stage CKD who are hospitalized with COVID-19 require increased awareness and close monitoring to reduce rates of ICU admission and mortality.

The present study aimed to investigate the prevalence, clinical, and laboratory characteristics of renal involvement in a large cohort of Ukrainian patients with systemic lupus erythematosus (SLE).
Methods. A total of 380 patients with SLE were enrolled in this cross-sectional study, including 176 with lupus nephritis (LN) and 204 with non-renal SLE. Patients were reviewed for demographic details, clinical SLE manifestations, SLE Disease Activity Index 2000 (SLEDAI-2K), and SLICC/ACR Damage Index. Laboratory evaluations included complete blood count with an erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), high-sensitivity CRP (hs-CRP), anti-CRP antibodies, serum creatinine, complement C3 and C4 levels, urinalysis, 24-hour urine protein, specific autoantibodies, interleukin-6 (IL-6), IL-10.
Results. There was a significantly higher frequency of malar rash, lymphadenopathy, splenomegaly, serositis, pulmonitis, fever, necrotizing vasculitis, and a history of arterial/venous thrombosis in patients with LN; while Raynaud’s phenomenon, Sjogren’s syndrome, peripheral nervous system manifestations occurred more often in patients with non-renal SLE. Patients with LN were found to have higher ESR levels and lower IL-10 levels. Either frequency of anti-dsDNA positivity and its titer were higher in the LN group with no differences regarding other autoantibodies. C3 and C4, CRP, hs-CRP, anti-CRP, and IL-6 levels showed no significant difference between the groups.
Multivariate analysis demonstrated that LN was positively associated with pulmonitis (OR 5.34 (95% CI 1.88-15.10), p=0.002), arterial/venous thrombosis (OR 6.80 (95% CI 1.87-24.70), p=0.004), anti-dsDNA positivity (OR 6.22 (95% CI 1.89-20.50), p=0.003), higher SLEDAI-2K score (OR 1.15 (95% CI 1.08-1.23), p<0.001) and negatively associated with Raynaud’s syndrome (OR 0.20 (95% CI 0.08-0.49), p<0.001) and younger age at disease onset (OR 0.96 (95% CI 0.93-0.99), p=0.003).
In the LN group, 27 patients (15.3%) had nephrotic syndrome. In multivariate logistic analysis, male sex (OR 5.21 (95% CI 1.77-15.30), p=0.003) and higher SLICC/ACR score (OR 2.12 (95% CI 1.45-3.09), p<0.001) were associated with increased risk of nephrotic syndrome, whereas lymphadenopathy (OR 0.31 (95% CI 0.12-0.80), p=0.02) was associated with decreased risk of nephrotic syndrome development.
Conclusions. Our cohort of Ukrainian LN patients showed different characteristics in demographic, clinical, and laboratory findings compared to patients with non-renal SLE. These features are mostly on par with LN patients of other nationalities around the world.
THE FLOW OF LUBRICANT IN A NARROW WEDGE-SHAPED SLOT WITH A MOVABLE WALL IS CONSIDERED

Published: July 2023

The article presents the results of a study of the lubricant flow in a narrow wedge-shaped slot with a movable wall. A solution to the problem with slip boundary conditions on the channel walls is obtained. The effect of slippage on the change in hydrostatic lift and hydraulic resistance in the slotted channel is shown.
It was determined in the work that with an increase in the slip intensity (an increase in the value of the Knudsen number), the pressure variation weakens. This is due to the weakening of the interaction of the flow with the wall. As a result, the hydraulic resistance is reduced.
The dependence of the relative hydrostatic lifting force on the Knudsen number and the opening angle of the channel is obtained. It is determined that with an increase in the Knudsen number, the magnitude of the hydrostatic lifting force decreases, since the influence of the flow on the wall weakens. The influence of slippage weakens with an increase in the opening angle of the channel.

ABSTRACTPopulation density in urban areas will cause urban social problems such as: limited yard areas, less interaction space, and stagnant water when it rains. The highest rainfall in Sekarbela District occurs from January to March with an average of 323-338 mm, this tends to cause puddles at several points including in the Bagek Kembar neighborhood area. The purpose of this service is to help residents of the Bagek Kembar neighborhood reduce rainwater stagnation, namely by making a simple infiltration hole commonly known as a biopore hole. The method used in this activity is socialization and direct manufacturing training. The socialization here is to provide knowledge and knowledge to partners about what biopori holes are, what are the benefits, and how the process is made. The socialization was carried out by "door to door" visiting each house chosen as the point for digging the biopore holes, with the elements involved being lecturers, students, employees, and residents (partners). The result is that residents have 2 to 3 biopori holes and become aware of the benefits and uses of these holes. Evaluation is carried out periodically, 3 months after manufacture.
