Abstract

A fabric can be modeled as an elastic beam supported by simple supports subjected to its own weight. The maximum deflection in the middle can be measured accurately. Different types of fabrics are tested and the bending modulus of the fabrics is then calculated in both small and large deflection cases. In the case of large deflection, the finite element method is used to solve the governing differential equation. The difference between the values of the bending modulus obtained from the small and large deflection cases increases as the length of the bent fabric is increased. The reason is less accuracy of the small deflection equations in longer lengths of the beam. However, the results reveal that even in the longest length of the tested beam (fabric), the differences between the values of the bending modulus from small and large deflection cases are in an acceptable range. It can be concluded that the case of the small deflection can be used to calculate the bending modulus of the fabrics in a simply supported beam method with an acceptable accuracy.

Abstract

Purpose

The regulation defines patients’ rights as a reflection of fundamental human rights in the field of medicine and incorporates all elements of patients’ rights accepted in international texts. Hence, the purpose of this paper is to investigate the relationship between patients’ safety, medical errors and patients’ safety rights with patients’ security feeling in selected hospitals of Mazandaran Province, Iran.

Design/methodology/approach

This descriptive cross-sectional study was conducted in selected hospitals of Mazandaran Province in public, social and private hospitals in 2016. In total, 1,083 patients were randomly selected for the study. The developed tool (questionnaire) was used for data collection. Questionnaire validity was verified through experts and its reliability was confirmed by Cronbach’s α coefficient (95 percent). Data were analyzed through multiple regressions by SPSS software (version 21).

Findings

The findings of this paper showed that the mean (standard deviation) medical error, patient’s safety, patient’s rights and patient’s security feeling were 2.50±0.61, 2.22±0.67, 2.11±0.68 and 2.73±0.63, respectively. Correlation testing results showed that medical error, patient’s safety and patient’s rights simultaneously had a significant relation with patient’s security feeling in the selected hospitals (p<0.05).

Originality/value

A simultaneous correlation between patient’s safety, patient’s rights and medical errors with patient’s security feeling in social security hospitals was higher than other hospitals. Hence, the authorities and officials of hospitals and healthcare centers were advised to make effective attempts to perceive the patient’s safety, medical errors and patient’s rights to improve the patient’s security feeling and calmness and also to make better decisions to promote the healthcare and therapeutic services.

Abstract

Purpose

The purpose of this paper is to analyse the seersucker fabrics from the point of view of their ability to ensure the thermo-physiological comfort. It was investigated how the kind of the weft yarn and seersucker structure influence the air permeability and thermal insulation properties of the fabrics.

Design/methodology/approach

The paper presents the investigations of the typical seersucker fabrics made of the same set of warps and different weft yarns. Fabrics were manufactured on the same loom with two warp beams. Next they were finished by the same way including washing, drying and stabilisation processes. Fabrics were measured in the range of their air permeability using standard test method. Thermal insulation properties of fabrics were measured in dry and wet state by means of Alambeta. Surface topography of the seersucker fabrics was analysed using 3D laser scanning.

Findings

On the basis of the obtained results it was stated that due to the puckered structure the seersucker fabrics are characterised by high thermal resistance, several times higher than the thermal resistance of typical flat woven fabrics. The seersucker fabrics are characterised by very low value of the thermal absorptivity in wet state at the level appropriate for typical flat fabrics in dry state. It confirmed that the seersucker fabrics ensure the physiological comfort. Application of the elastomeric yarn in weft caused significant tightening the fabric structure. It resulted in low air permeability, fabric stiffness and unpleasant hand.

Research limitations/implications

As a limitation of the investigation of the seersucker fabrics in wet state we can mention the surface topography of the fabrics. It made wetting the fabrics difficult before measuring. It is necessary to elaborate precise procedure of preparation of seersucker fabrics before their testing in the wet state.

Practical implications

Performed investigations showed that the seersucker fabrics have a big potential to be comfortable. By an appropriate designing of their structure it is possible to achieve very good comfort-related properties even without application of innovative comfort-oriented yarns.

Originality/value

The originality of the paper is based on the fact that the measurement was performed for the seersucker fabrics. The fabrics are characterised by the unique structure which influences their appearance and utility properties. It caused that they are willingly applied in different kinds of clothing. Till now any results of comfort-related properties of such kind of the woven fabrics have not been published.

Abstract

Purpose

This study concentrates on South Korean university students' attitude towards cooperative learning by utilizing the “Student Attitudes toward Group Environments” survey (n = 427–181 female and 246 male) originally developed by Kouros and Abrami (2006).

Design/methodology/approach

The purpose of this study is to unfold what factors affect the cooperative learning environment in the Higher Education context of South Korea, which is known as a collectivist society, and conduct comparative analysis on gender, department type, GPA level and school year as variables in the perception of cooperative learning. The factor analysis findings demonstrated that there are four factors influencing students' attitude about cooperative learning environments in South Korean higher education; “frustrations with group members”, “peer support”, “fairness” and “quality of product and process”. Moreover, the gender, type of department, school year and GPA variables were yielded statistically differentiating results.

Findings

The overall results showed that effective cooperative learning strategies depend on the type of culture and other demographic variables including learner's gender, department type and school year. In South Korea, known to have a collectivist culture, fairness has appeared as a new criteria needing to be considered when designing a cooperative learning environment, which is a different case than in individualistic cultures. Thus, when employing cooperative learning strategies in South Korea, educators should take learners' culture into consideration. For this, educators might utilize the final instrument of this study as a guideline or criteria to establish an effective cooperative learning environment.

Originality/value

This article provides an example from South Korea which is known as both a collectivist and high-tech country.

Abstract

Purpose

Academic and industrial researches on nanoscale flows and heat transfers are an area of increasing global interest, where fascinating phenomena are always observed, e.g. admirable water or air permeation and remarkable thermal conductivity. The purpose of this paper is to reveal the phenomena by the fractional calculus.

Design/methodology/approach

This paper begins with the continuum assumption in conventional theories, and then the fractional Gauss’ divergence theorems are used to derive fractional differential equations in fractal media. Fractional derivatives are introduced heuristically by the variational iteration method, and fractal derivatives are explained geometrically. Some effective analytical approaches to fractional differential equations, e.g. the variational iteration method, the homotopy perturbation method and the fractional complex transform, are outlined and the main solution processes are given.

Findings

Heat conduction in silk cocoon and ground water flow are modeled by the local fractional calculus, the solutions can explain well experimental observations.

Originality/value

Particular attention is paid throughout the paper to giving an intuitive grasp for fractional calculus. Most cited references are within last five years, catching the most frontier of the research. Some ideas on this review paper are first appeared.
