Factors Determining Adoption of Fintech Peer-to-Peer Lending Platform: An Empirical Study in Indonesia

Rudy SUNARDI,Hamidah HAMIDAH,Agung Dharmawan BUCHDADI,Dedi PURWANA 한국유통과학회 2022 The Journal of Asian Finance, Economics and Busine Vol.9 No.1

Platform lending or online lending, sometimes called peer-to-peer (P2P) lending, arose due to the digital revolution to meet people’s requirements for simple fund borrowing. It quickly became an alternative to other traditional lending techniques, for example, loans banks. Along with the growth of P2P lending, several academics have investigated how information technology is used in financial services, emphasizing extended application methods. This study proposes an enhanced technology acceptance model (TAM) that investigates how consumers embrace P2P lending platforms by using quality of service and perceived risk as drivers of trust, relative advantage and compatibility as drivers of perceived usefulness. For the purpose of this study, we created a questionnaire, distributed it to clients of P2P lending platforms and fintech services in general in cities in Java, Indonesia. We received 290 replies to our questionnaire. The data was analyzed to test the hypotheses using structural equation modeling (SEM). The findings show that consumers’ trust, relative advantage, perceived usefulness, and perceived ease of use in P2P lending platforms substantially affect their views toward adoption. The research’s findings are useful for fine-tuning platform marketing strategies and putting strategic goals into action.

A note on Snevily's conjecture in set systems

Rudy X. J. Liu,황경원,김연진 장전수학회 2017 Advanced Studies in Contemporary Mathematics Vol.27 No.1

Let L = {l1, l2, . . . , ls} be a set of s nonnegative integers and K = {k1, k2, . . . , kr} be a set of integers satisfying max lj < min ki. Let F be an L-intersecting family of subsets of {1, 2, . . . , n} such that |F| ∈ K for every F ∈ F. Let {0, 1, . . . , s - r - 1} ⊆ L with 1 < r < s and K be any set of integers with min ki > s - r and K ∩ L = Ø. Then |F| ≤ (n-1s)+(n-1s-1)+…+(n-1s-r). These results conrm Snevily's conjecture on set systems partially.

Optimal Sizing of BESS for Hybrid Electric Ship Using Multi-Objective Particle Swarm Optimization

Rudy Tjandra,Shuli Wen,Dehong Zhou,Yi Tang 전력전자학회 2019 ICPE(ISPE)논문집 Vol.2019 No.5

This paper presents an optimal sizing technique of Battery Energy Storage System (BESS) in Hybrid Electric Ship. The technique is based on both Multi-Objective Particle Swarm Optimization (MOPSO) and Non-Dominated Sorting-based Genetics Algorithm II (NSGA II). Both total installed BESS size (kWh) and total fuel consumption are the objectives of the optimization. To meet the target lifespan of BESS, Depth-of-Discharge (DOD) of BESS is used as design variable together with usable energy of BESS. An example based on ferry case study has been studied. From the sizing technique, Pareto front is obtained. The ship designer or user can choose one of the results from the Pareto front based on their goal or requirement.

Rapid Bodyweight Reduction before Lumbar Fusion Surgery Increased Postoperative Complications

Rudy Hayeem L.,Cho Woojin,Oster Brittany A.,Tarpada Sandip Parshottam,Moran-Atkin Erin 대한척추외과학회 2020 Asian Spine Journal Vol.14 No.5

Study Design: Retrospective cohort study.Purpose: To determine the effects of massive weight loss on perioperative complications after lumbar fusion surgery (LFS).Overview of Literature: Patients who are obese are more likely to experience low back pain, which would require LFS. Nonetheless, they have a higher risk of perioperative complication development compared with individuals who are not obese.Methods: Patients who underwent LFS at hospitals that participated in the National Surgical Quality Improvement Program database within the United States between 2005 and 2015. Outcomes included 30-day medical complications, surgical complications, and length of stay (LOS). We analyzed a total of 39,742 patients with the use of the International Classification of Disease, ninth revision codes. The patients were categorized in the following two groups: group 1, individuals with a history of massive weight loss within 6 months before LFS, and group 2, individuals without a history of massive weight loss before surgery. Massive weight loss was defined as loss of 10% of total body weight. Patients with a history of malignancy or chronic disease were excluded from the study. Patients in each group were randomly matched based on age, gender, sex, smoking status, and body mass index. Paired two-tailed Student t -tests were used to compare the outcomes.Results: Of the 39,742 patients identified, 129 (0.32%) met the criteria for inclusion in the weight loss group (WL group) and were successfully matched to individuals in the non-weight loss group (non-WL group). Compared with the non-WL group, the WL group had a significantly longer LOS (9.7 vs. 4.0 days, p <0.05), higher surgical site infections (SSIs) (8.0 vs. 3.0, p <0.05), increased number of blood transfusions (40.0 vs. 20.0, p <0.05), and greater deep vein thrombosis (DVTs) (5.0 and 0.00, p <0.05).Conclusions: On a nationwide scale, rapid weight loss before LFS is associated with a higher rate of postoperative complications, including SSI and DVTs, longer average LOS, and more frequent blood transfusions.

Mitogenic Signal Transduction by Integrin- and Growth Factor Receptor-mediated Pathways

Rudy Juliano,이정원 한국분자세포생물학회 2004 Molecules and cells Vol.17 No.2

Engagement of cells with the extracellular matrix (ECM) proteins is crucial for various biological proc-esses, including cell adhesion, spreading, proliferation, differentiation, migration, apoptosis, and gene induc-tion, contributing to maintenance of tissue integrity, embryogenesis, wound healing, and the metastasis of tumor cells (Hynes, 2002b; Juliano, 2002). The en-gagement involves cell adhesion mediated by integrins, a large family of cell adhesion receptors that are transmembrane glycoproteins which bind to ECM or to counter-receptors on neighbor cells. In this review, the molecular basis of signaling mediated by integrins and their collaboration with growth factor receptors will be discussed, based on recent observations. Although other cell adhesion receptors including cadherins, se-lectins, syndecans, and the immunoglobulin superfamily of cell adhesion molecules (IgCAMs) can play important roles or be involved in these processes, we suggest read-ers refer to recent outstanding reviews on them (Barclay, 2003; Brummendorf and Lemmon 2001; Panicker et al. 2003).

Efficacy and Safety of a Flaxseed Hull Extract in the Symptomatic Management of Benign Prostatic Hyperplasia: A Parallel, Randomized, Double-Blind, Placebo-Controlled, Pilot Study

Rudy Simons,Navneet Sonawane,Marian Verbruggen,Jayesh Chaudhary 한국식품영양과학회 2015 Journal of medicinal food Vol.18 No.2

This exploratory study was designed to assess the effectiveness of a lignan-rich extract of flaxseed hulls (LinumLife EXTRA®) in alleviating symptoms in subjects with benign prostatic hyperplasia (BPH) compared with placebo. Two dosages of extract were compared against placebo in a double-blinded, randomized, parallel, multicenter study. Newly diagnosed cases of BPH in patients aged 45–75 years with an American Urological Association Symptom Index (AUASI) score of ≥ 13 were included. Study treatment consisted of 500 or 1000 mg of extract containing 100 mg (low-dose active [LDA] group, n = 26) or 200 mg (high-dose active [HDA] group, n = 26) of secoisolariciresinol diglucoside (SDG), respectively. The placebo (P) group (n = 28) received matching maltodextrin capsules. Sixty subjects (LDA [n = 19], HDA [n = 20], and P [n = 21]) completed the study as per the protocol requirements. Change in the AUASI score within a period of 8 weeks, from baseline to end of treatment, was assessed. Significant improvement of obstructive symptoms and management of irritable BPH symptoms was achieved in all groups after treatment. Due to a strong placebo effect, there was no statistical difference between the groups that were treated with flaxseed hull extract as compared with the placebo group. Treatment with flaxseed hull extract did not lead to adverse effects compared with placebo. Supplementation with flaxseed hull extract was found to be safe and well-tolerated and may have improved the quality of life of individuals with BPH. The significant placebo effect as well as the number of subjects per treatment group and the relative short duration of the study may explain the lack of statistical significance between groups.
