Second Wave

The need for oxygen, as well as the scarcity caused by the second wave of the Corona epidemic, has caused everyone to reconsider the sustainability and self-sufficiency of oxygen. Medical oxygen therapy is a standard treatment for patients with severe Covid manifestations. Ensuring a consistent supply of oxygen to meet the rising demand for oxygen must be planned at the national, state, and institutional levels. In this article we would like to emphasise the importance of oxygen adequacy. This narrative review covers the methods of estimating oxygen requirements of a hospital, and the alternate oxygen sources available, highlighting the role of oxygen concentrators in a low resource settings. Oxygen concentrators specially as pressure swing adsorption plants can be used by hospitals as a main source of oxygen being both economical, as well as reducing the dependency on refilling and transport. Planning the oxygen resources for a hospital should include primary, secondary and reserve sources, among all these the oxygen concentrator plays a vital role both being economical in the long run as well as making the hospital largely independent of logistic issues.

Financing Option

Muslims in Malaysia had practiced ar-rahnu for fulfilling their financial need, especially for emergency purposes since early 1990s. The pioneer of ar-rahnu in Malaysia is Muassasah Gadaian Islam Terengganu (MGIT) in January 1992, followed by the Kelantan Capitalization Berhad (PKB) in March 1992. Both of these Islamic pawn centres are among the earliest exponents to the Islamic pawn scheme in Malaysia. Ar-rahnu is an increasingly popular financing option among micro-entrepreneurs in Malaysia, particularly women micro-entrepreneurs. Women micro-entrepreneurs play a vital role in the Malaysian economy and could be considered as the backbone of the industrial development in Malaysia. This study examines the role of ar-rahnu as a source of financial stability for women micro-entrepreneurs. 600 questionnaires were distributed at three states in Malaysia which are Kelantan, Terengganu and Kedah. Then, this study used SPSS and SEM Amos to analyses the data for 600 respondents (women micro-entrepreneurs) in Malaysia. In essence, this study finds that shariah compliancy, locality, service charges, collateral and customer satisfaction has positive and significant impact towards the use of ar-rahnu. The study also found use of ar-rahnu has significant impact towards financial self-sufficiency for women micro-entrepreneurs. Keywords: Women, Micro-entrepreneurs, Self - sufficiency, Financial stabilityJEL Classification: G20, G21

The paper provides the in-deep analysis of the theoretical background of the necessity and efficiency of the ecological component of corporate social responsibility. The distinguish features of four approaches of corporate social responsibility are identified in order to build a comprehensive view of the evolution of the understanding the vital role of the nature in the context of reaching the long-run goals of business and humanity in general. Additionally, sustainability policies of the most ecologically responsible companies were studied to monitor the specifics of their formulation and the ways to prevent the environmental degradation and climate change. Moreover, the implemented eco-oriented activities by companies were analysed to classify the common activities and to evaluate the level of their involvement. The results indicated the gap between the well-developed theoretical background and the poor participation of business in solving and prevention ecological issues.
