Elvin P. ROSARIO(Elvin P. ROSARIO ) 한국유통과학회 2023 The Journal of Asian Finance, Economics and Busine Vol.10 No.1

The purpose of this research was to determine the degree to which Small-to-Medium Enterprise (SME) owners and operators in Mountain Province were willing to take on financial risk to invest in the capital markets as a potential additional source of income, as well as the extent to which these five indicator variables—particularly their income, expenses, financial goals, liquid cash, and insurance coverage—were influenced by demographic factors. The study used a quantitative approach and employed a descriptive survey research method. The results show that the SME Owners and Operators in Mountain Province have minimal knowledge of capital market investments which makes them moderate investors with a neutral level of financial risk tolerance toward capital market investment. Their marital status, net income, and educational attainment significantly influence their financial risk tolerance level. The respondents also believe that engaging in the capital markets will grow their businesses. Further, the extent of influence of Income, Expenses, Liquid Cash, and Insurance Cover on the financial risk tolerance of the SME owners and operators in Mountain Province a great extent; thus, making them careful in investing in the capital markets, and it is primarily affected by their Net Income. Consequently, the financial goals of SME owners and operators in Mountain Province have a vital role in their financial risk tolerance level.

Rosario Pecora,Francesco Amoroso,Gianluca Amendola,Antonio Concilio 국제구조공학회 2014 Smart Structures and Systems, An International Jou Vol.14 No.4

The study is aimed at investigating the feasibility of a high TRL solution for a wing flap segment characterized by morphable camber airfoil and properly tailored to be implemented on a real-scale regional transportation aircraft. On the base of specific aerodynamic requirements in terms of target airfoil shapes and related external loads, the structural layout of the device was preliminarily defined. Advanced FE analyses were then carried out in order to properly size the load-carrying structure and the embedded actuation system. A full scale limited span prototype was finally manufactured and tested to: • demonstrate the morphing capability of the conceived structural layout; • demonstrate the capability of the morphing structure to withstand static loads representative of the limit aerodynamic pressures expected in service; • characterize the dynamic behavior of the morphing structure through the identification of the most significant normal modes. Obtained results showed high correlation levels with respect to numerical expectations thus proving the compliance of the device with the design requirements as well as the goodness of modeling approaches implemented during the design phase.

Rigid plastic analysis for the seismic performance evaluation of steel storage racks

Rosario Montuori,Giammaria Gabbianelli,Elide Nastri,Marco Simoncelli 국제구조공학회 2019 Steel and Composite Structures, An International J Vol.32 No.1

The aim of the paper is the prediction of the seismic collapse mode of steel storage pallet racks under seismic loads. The attention paid by the researchers on the behaviour of the industrial steel storage pallets racks is increased over the years thanks to their high dead-to-live load ratio. In fact, these structures, generally made by cold-formed thin-walled profiles, present very low structural costs but can support large and expensive loads. The paper presents a prediction of the seismic collapse modes of multi-storey racks. The analysis of the possible collapse modes has been made by an approach based on the kinematic theorem of plastic collapse extended to the second order effects by means of the concept of collapse mechanism equilibrium curve. In this way, the dissipative behaviour of racks is determined with a simpler method than the pushover analysis. Parametric analyses have been performed on 24 racks, differing for the geometric layout and cross-section of the components, designed in according to the EN16618 and EN15512 requirements. The obtained results have highlighted that, in all the considered cases, the global collapse mechanism, that is the safest one, never develops, leading to a dangerous situation that must be avoided to preserve the structure during a seismic event. Although the studied racks follow all the codes prescriptions, the development of a dissipative collapse mechanism is not achieved. In addition, also the variability of load distribution has been considered, reflecting the different pallet positions assumed during the in-service life of the racks, to point out its influence on the collapse mechanism. The information carried out from the paper can be very useful for designers and manufacturers because it allows to better understand the racks behaviour in seismic load condition.

Modeling of wind-induced fatigue of cold-formed steel sheet panels

Rosario-Galanes, Osvaldo,Godoy, Luis A. Techno-Press 2014 Structural Engineering and Mechanics, An Int'l Jou Vol.49 No.2

Wind-induced failure around screwed connections has been documented in roof and wall cladding systems made with steel sheet cold-formed panels during high wind events. Previous research has found that low cycle fatigue caused by stress concentration and fluctuating wind loads is responsible for most such failures. A dynamic load protocol was employed in this work to represent fatigue under wind effects. A finite element model and fatigue criteria were implemented and compared with laboratory experiments in order to predict the fatigue failure associated with fluctuating wind loads. Results are used to develop an analytical model which can be employed for the fatigue analysis of steel cold-formed cladding systems. Existing three dimensional fatigue criteria are implemented and correlated with fatigue damage observed on steel claddings. Parametric studies are used to formulate suitable yet simple fatigue criteria. Fatigue failure is predicted in different configurations of loads, types of connections, and thicknesses of steel folded plate cladding. The analytical model, which correlated with experimental results reported in a companion paper, was validated for the fatigue life prediction and failure mechanism of different connection types and thicknesses of cold-formed steel cladding.

Purpose: The purpose of this study was to develop the modified research utilization questionnaire (MRUQ) and to establish its content and face validity, construct validity, and reliability. Methods: This study has a multiphase (three phases), methodological, and cross-sectional design. First, research utilization questionnaire (RUQ) was translated into Italian, which is the target language to develop the M-RUQ. Second, the RUQ psychometric proprieties were assessed using exploratory factorial analysis to identify ambiguous or problematic items (e.g., cross-loadings) (cross-sectional sampling A). The RUQ modification (i.e., item deleting, wording modification, and scoring procedure) represented the development of the M-RUQ among Italian nurses. The third phase was aimed to confirm the construct validity of the M-RUQ and to test its stability and internal consistency (crosssectional sampling B). Results: This study's findings show that M-RUQ has a three-dimensional structure and a total of 22 items. The M-RUQ shows evidence of validity and reliability. Precisely, the factorial structure coming from an exploratory factorial analysis on the first sample (n ¼ 504) was confirmed by a final model of confirmatory factorial analysis (CFA) on a second sample (n ¼ 362). The final CFA model showed adequate goodness of fit, where all the factor loadings showed values higher than .40. Cronbach's a was satisfactory for each domain and for the overall scale. Furthermore, the M-RUQ showed good stability described by the testeretest. Conclusion: The M-RUQ should be used to assess research utilization among nurses for educational or research purposes to address the practice. Further research about its validity and reliability is suggested.

Rosario Montuori,Elide Nastri,Maria Ilenia Palese,Vincenzo Piluso 사단법인 한국계산역학회 2019 Computers and Concrete, An International Journal Vol.24 No.3

The work aims at the comparison among commonly used research programs concerning moment-curvature (M−χ) diagrams of confined R.C. members. The software considered in this work are Sap2000, SeismoStruct and Opensees. The curves provided by these software, given the same modelling, have been compared to those provided by a theoretical fiber model. A parametric analysis has been led on rectangular column sections with different level of axial load and different stirrups spacing. The accuracy of the modelling of the considered structural programs has been investigated by comparing their results with those obtained by applying the theoretical fiber model.

Rosario Prisco,Giuseppe Troiano,Luigi Laino,Khrystyna Zhurakivska 대한치과보철학회 2021 The Journal of Advanced Prosthodontics Vol.13 No.6

PURPOSE. The success of an implant-prosthetic rehabilitation is influenced by good implant health and an excellent implant-prosthetic coupling. The stability of implant-prosthetic connection is influenced by the rotational tolerance between anti-rotational features on the implant and those on the prosthetic component. The aim of this study is to investigate the rotational tolerance of a conical connection implant system and its titanium abutment counterpart, in various conditions. MATERIAL AND METHODS. 10 preparable titanium abutments, having zero-degree angulation (MegaGen, Daegu, Korea) with an internal 5-degree conical connection, and 10 implants (MegaGen, Daegu, Korea) were used. Rotational tolerance between the connection of implant and titanium abutments was measured through the use of a tridimensional optics measuring system (Quick Scope QS250Z, Mitutoyo, Kawasaki, Japan) in the as-received condition (Time 0), after securing with a titanium screw tightening at 35 Ncm (Time 1), after tightening 4 times at 35 Ncm (Time 2), after tightening one more time at 45 Ncm (Time 3), and after tightening another 4 times at 45 Ncm (Time 4). RESULTS. The group “Time 0” had the lowest values of rotational freedom (0.22 ± 0.76 degrees), followed by the group Time 1 (0.46 ± 0.83 degrees), the group Time 2 (1.01 ± 0.20 degrees), the group Time 3 (1.30 ± 0.85 degrees), and the group Time 4 (1.49 ± 0.17 degrees). CONCLUSION. The rotational tolerance of a conical connection is low in the “as received” condition but increases with repetitive tightening and with application of a torque greater than 35 Ncm.

Compression Techniques for DNA Sequences: A Thematic Review

Rosario Gilmary,Akila Venkatesan,Govindasamy Vaiyapuri 한국정보과학회 2021 Journal of Computing Science and Engineering Vol.15 No.2

Deoxyribonucleic acid (DNA) is the basic entity that carries genetic instructions. This information is used in the evolution, progression, and improvement of all species. It is estimated that 10 CD-ROMs are required to store the genomic data of an individual being. With the increase in DNA sequencing equipment, an extensive heap of genomic data is created. The increase in DNA data in public databases is surpassing the rate of growth in storage space, thereby raising a significant concern related to data storage, transmission, retrieval, and search. To reduce the data storage and storage expense, lossless compression procedures were applied. Conventional compression methods are not proficient while compressing the biological data. Hence, several unique and contemporary lossless compression mechanisms were used to achieve improved compression ratio in biological sequences. Here, we scrutinize the diverse existing compression procedures that are appropriate for the compression of DNA sequences. The efficiency of algorithms is compared in terms of compression ratio, the ratio of the capacity of the compressed folder, and compression/decompression time. Main challenges and future research directions in DNA compression are also presented. Emphasis has been given to special references related to contemporary techniques.
