The purpose of this paper is to develop a unique disposable bed sheet design which reduces infection risk and other related problems from patient to patient and others during staying period at hospitals.

The unique disposable bed sheet consists of three layers which are laminated to each other by hot‐melt technique. Upper and lower layers are different weights of 100 per cent polypropylene produced by spunbond technology. Plasma technology has been used to make the surface of the spunbond polypropylene sheets hydrophilic. Additionally, thermal bond 100 per cent polypropylene sheets, which have hydrophilic surfaces already due to chemical finish have been also used as upper layer. As core layer, different weights of 100 per cent viscose sheets, which have high liquid‐absorption capacity have been used. All three layers have been laminated by hot‐melt technique using etylene vinyl acetate interlayers between them. Antimicrobial effect has been achieved by the impregnation of silver and antibiotic‐based chemicals onto the hydrophilic surface of upper layers. Quality control and performance tests of all these works have been performed according to ISO and BS norms.

It is possible to have very good liquid suction capacity together with superb comfort properties, thanks to its viscose intermediate sheet and excellent wetback values. Moreover, it is initially cheap, hygienic and has enough strength against breaking and tearing.

Cheaper antimicrobial agents and different application amounts should be checked. Also, durability of the hydrophilicity given by plasma treatment has to be checked. Additionally, dermatological tests should be applied.

It is expected that the infection risk at hospitals will be reduced. Moreover, hospitals will be able to use hygienic bed sheets, which would be preferable to the hospital management. Additionally, this unique design can be used for patients at home or for injured animals in veterinary clinics.

Additional staying period due to hospital infections and infections from patient to patient/hospital personnel/visitors/other people will be reduced. Moreover, it is expected that life quality will be raised and dead ratio will be decreased. Beside this, manpower loss and increasing costs due to hospital infections will be prevented.

Design is new and unique. It has practical and social implications.

Rapid developments in social networks and their usage in everyday life have caused an explosion in the amount of short electronic documents. Thus, the need to classify this type of document based on their content has a significant implication in many applications. The need to classify these documents in relevant classes according to their text contents should be interested in many practical reasons. Short-text classification is an essential step in many applications, such as spam filtering, sentiment analysis, Twitter personalization, customer review and many other applications related to social networks. Reviews on short text and its application are limited. Thus, this paper aims to discuss the characteristics of short text, its challenges and difficulties in classification. The paper attempt to introduce all stages in principle classification, the technique used in each stage and the possible development trend in each stage.

The paper as a review of the main aspect of short-text classification. The paper is structured based on the classification task stage.

This paper discusses related issues and approaches to these problems. Further research could be conducted to address the challenges in short texts and avoid poor accuracy in classification. Problems in low performance can be solved by using optimized solutions, such as genetic algorithms that are powerful in enhancing the quality of selected features. Soft computing solution has a fuzzy logic that makes short-text problems a promising area of research.

Using a powerful short-text classification method significantly affects many applications in terms of efficiency enhancement. Current solutions still have low performance, implying the need for improvement. This paper discusses related issues and approaches to these problems.
