    ABSTRACT: Hotel guests facing emergencies in stricken destinations far from home are more vulnerable and require effective emergency planning and recovery. This poses a great challenge to any hotel business. Emergencies affecting the hotel industry become more frequent and complex than before. By using secondary data, this paper aims to shed light on hotels’ vulnerability to emergencies and the points which may increase this vulnerability. Lessons learnt from these emergencies will be explained further. The findings revealed that still there is a gap between what was planned and what happens during emergencies. Poor emergency planning leads to poor emergency management. Initially, there is a failure to recognize the difference between the emergency planning and emergency management principles. Several lessons could be learnt from the literature which proposes effective planning for emergencies to help overcome the impacts of disasters. Furthermore, studying and practicing emergency management in the hotel industry will answer the important question, did we learnt the lesson?

    ABSTRACT: This paper aims to identify the potential for major emergencies which can occur in Jordanian hotels; questions asked to investigate how these hotels were prepared for emergencies, how they manage and overcome emergencies when they occur; and explore their limitations. The factors influencing successful emergency planning and adoption emergency management in the Jordanian hotels will also be observed. By using qualitative methodology, face-to-face interviews for managers were conducted at three, four and five star hotels. Different backgrounds; such as local, regional and international among the cities of Amman and Petra were also considered. Results revealed that Jordanian hotels are exposed to a wide range of natural and man-made disasters. Jordanian hotels lack proactive emergency planning with many constraints which impede successful emergency planning. Emphasizing the relevant role of authority to demonstrate emergency management to hotels and trying to convince them to adopt such practices in order to cope with emergencies effectively is a unique challenge.

    ABSTRACT: The increasing cost of energy especially with the recent electricity tariff hike in Malaysia has made home owners to be mindful of ways to reduce energy consumption. There are many ways to cut energy consumption at home, fundamentally they can be grouped into two types of approach namely technological and behavioural approach. Both approaches are not easy to implement as the technological one requires replacement of old devices and the behavioural one requires change of lifestyle. In view of this, this research work attempts to apply the theory of inventive problem-solving, TRIZ to solve the problem of increasing consumption of electricity at home. The aim of this research is to derive potential conceptual solutions to help home owners to reduce their energy consumption. The reduction in energy used will also contribute to cost saving for household and the reduction of carbon footprint.

    ABSTRACT: This paper highlights the antihypertensive effects of Lentinus sajor-caju, a wild edible white rot mushroom. The 6-week old male spontaneously hypertensive rats (SHR) and normotensive Wistar Kyoto rats (WKY) were orally administered with 1 ml/100g of body weight of the prepared extract concentrations (0.0 mg/kg, 38.5 mg/kg, and 77.0 mg/kg dosages) of L. sajor-caju once-daily for 16 weeks. The blood pressure and heart rate were monitored once a week and blood of mice was drawn at the end of the experiment for blood chemistry analyses. Results revealed that hot water extract of L. sajor-caju (WELS), was found to exhibit lowering effects in the systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate when orally administered to SHR. The antihypertensive actions of WELS were also demonstrated by improve metabolic activities as indicated by the blood chemistry clearance. WELS at 38.5 mg/kg or higher dose significantly lowered the values of triglycerides (TG), blood urea nitrogen (BUN) and creatinine (Cre), and significantly increased the values of total cholesterol (T-Cho), high-density lipoprotein-cholesterol (HDL-C), albumin/globulin ratio (A/G ratio) in SHR. Therefore, WELS has a promising contribution in the prevention of hypertension development.

    ABSTRACT: Background: Orchidaceae species has developed into one of the significant industrial products in agricultural industry globally. Beside as potted flower, they serve as cut flowers since they have eye-catching pigments in the flower petals. Objective: The main pigments from orchid’s flower petals were investigated and their relations with phenylalanine ammonia-lyase (PAL) activity were evaluated. Results: Total anthocyanin content of six different orchids’ petals was determined specthrophotometrically and the value ranged from 0 mg/g (in Dendrobium Shavin white) to 2.128 mg/g (in Mokara Aranda). Total anthocyanin content was found to be the highest when compare to β-carotene and chlorophyll content. In correlation analysis, PAL activity was found to be significant positive correlated with the anthocyanin content. Conclusion: The results indicate the potential for PAL enzyme as a biomarker for flower colour in orchids.
