International Education Studies , 2011, DOI: 10.5539/ies.v4n2p153
Abstract: The role of Information and Communication Technology (ICT) in education has been peripheral, with new technologies being added to the traditional teacher centred model of instruction. Students in the global economy of the 21st Century need to be creative thinkers and innovators. Thus, this paper provides an overview of the integration of innovation and education which plays an important role in propelling the human capital to a higher level to realize the objectives of Vision 2020.The integration of teaching and research is becoming a key issue in higher education, not only in order to differentiate the character of universities from other teaching and learning institutions, but also in order to find ways to create the kind of knowledge needed in a world characterized by a turbulent environment and increasing change in daily life.The right blend of pedagogies, tools and media needs to be created, quality assurance at various stages of planning, design and implementation should be embedded at every stage to ensure that we produce the desired graduates.

Siti Zubaidah Sulaiman,A. Luqman Chuah,A. Fakhru`l-Razi
Journal of Applied Sciences , 2007,
Abstract: A batch process for the ransesterification of Palm Oil Methyl Ester (POME) with trimethylolpropane (TMP) to TMP ester was investigated in a mini pilot reactor. The process was equipped with a high vacuum pump. The experimental studies explored effects of vacuum pressure, temperature, molar ratio, catalyst amount and agitator speed on the overall conversion. Five liters of TMP esters containing 83 to 87 w/w % triesterss (TE) were successfully synthesized after 2 h of reaction time Application of vacuum pump enhanced conversion of TE (w/w %) for the process. High catalyst amount resulted in higher conversion of TE (w/w %) but increased in solid content of the product. This has reduced the product yield due to inefficient separation by gravity settling.

Natural Science (NS) , 2012, DOI: 10.4236/ns.2012.42017
Abstract: Development of gamma irradiated high moisture traditional dishes derived from locally traditional récipe aimed for specific target groups as ready to eat foods for ensuring the safety, quality, and security purposes have been conducted. The formation of free radicals in the traditional foods induced by ionizing radiation is a part of toxicological studies on irradiated traditional foods was to provide local scientific data base on safe- ty issues.The different foods such as steamed gold fish, spicy curry beef and soy sauces beef were individually vacuum packed in a laminate pouch of PET 12 μm/LDPE 2 μm/AL-Foil 7 μm/LDPE 2 μm/LLDPE 50 μm (PET/Al-Foil/ LLDPE), then kept at frozen state. The frozen samples were maintained in cryogenic condition along the irradiation process by placing the samples in styrofoam boxes filled with dry ice then irradiated with gamma rays at the dose of 45 kGy. The irradiated samples were kept and stored at normal temperature prior to test. Both irradiated conventional rat’s feed at normal temperature with the dose of 4 kGy and unirradiated one as control were also made. Irradiated and unirradiated samples were sent to animal laboratory, and fed into individual female Sprague Dawley rat as member of a group. The parameters observed were body weight changed of rats, toxicological test to observe the effect free radicals formation in rat’s blood by using malon-dialdehyde (MDA) and superoxide dismutase (SOD) methods, respectively, and anatomy pathology diagnosis. Different types of the foods sterilized by ionizing radiation fed ad libitum to the individual Sprague Dawley rat demonstrated that such foods did not give any adverse effect on the reduction of body weight, the toxicological impact, nor anatomy-pathology examinations of the rats.

Abstract:

The addition of prebiotic in food today is mostly done. It is based on the ability of prebiotic to support the growth of probiotic. Inulin is a carbohydrate that serves as an effective prebiotic that cannot be digested by digestive enzymes. The purpose of this research is to assess utilization of inulin from several types of tubers include dahlia tubers, yam tu- bers, and gembili tubers as a source of prebiotic that tested in probiotic bacteria (L. casei and L. plantarum). The study used a Randomized Block Design method with two factors, the type of probiotic isolate and inulin extract from tubers. The result shows that the best treatment is isolates of L. casei obtained in the fermentation medium with the addition of inulin from gembili tubers. The best treatment has the following characteristics: an increase in total LAB 2.71 × 1010 cfu/ml, 1.50% total acid, pH 2.05 and the total sugars are 3.11%. Whereas in isolates of L. plantarum, the best treatment in the fermentation medium is with the addition of inulin from dahlia tubers. The LAB reaches 2.80 × 1010 cfu/ml, 1.29% total acid, pH 2.24 and 2.05% total sugars.

Jurnal Teknologi dan Industri Pangan , 2008,
Abstract: Several factors such as insufficient harvesting and handling methods as well as inadequate methods of storage and distribution, poor processing techniques and poor quality of raw materials used in making ready to eat foods may lead to the cumulative causes of food borne illness particularly in developing countries. Public trend in the world nowadays are demanding access to more and more fresh eating products practical but nutritious, safe and preferably processed under non thermal treatments. The new and emerging post harvest technologies in controlling pathogen and maintaining quality of food products is ionizing radiation, because it is applicable for almost all type of foods without impairing the overall quality as well as sensory attributes. The foods either fresh, dried, or ready to eat meals in the packages can be exposed to ionizing radiation for different purposes such as quarantine measures, control of sprouting and germination, shelf-life extension of perishable foods, delaying ripening and aging of fruits and vegetables, destruction of parasites and harmful pathogenic microorganisms. International trade of agricultural commodities opens the possibility of the movement of pests such as insects from country to country. The countries involve in this business have established laws and regulations, including international trade regulation of irradiated foods, in order to minimize the risk and trade barrier. The future of food irradiation is filled with promise although the needs for this technique relates to consumer acceptance. Consumers will grow to appreciate the technology for the lifesaving and good food availability. It should be kept in mind that irradiation is controlling contamination and it does not prevent it.

Abstract: Evidence showed occupational factors may contribute distress to breast cancer survivors, however, very few studies focused on the occupational factors and job strain among breast cancer survivors. This study examined the relationship between job strain and workplace stressors with psychological distress among employed breast cancer survivors after the completion of their medical treatment. Study subject were outpatients of 2 hospitals and members of 4 breast cancer support groups. They were requested to fill up the Job Content Questionnaires (JCQ), the Hospital Anxiety and Depression Scale (HADS) and the Distress Thermometer (DT) were filled up by the selected respondents. On simple logistic regression, psychological job demand and job strain were significantly associated with anxiety, distress on HADS-T and DT at (p < 0.001). While, psychological job demand (p < 0.001), social support (p = 0.047) and job strain (p < 0.001) were significantly associated with depression. Results showed survivors with high job strain has 4.74 time the odds of having anxiety (p < 0.001). Survivors with high psychological job demand have 8.08 time the odds of getting depression (p < 0.001). On the other hand, social support served as a protective factor of depression, (p = 0.041). Survivors with high psychological job demand were 4.4 time the odds of having distress (HADS-T) (p = 0.012). As a conclusion, survivors who experienced high psychological job demand, low social support and high job strain were reported with anxiety, depression or psychological distress.

Creative Education (CE) , 2017, DOI: 10.4236/ce.2017.89097
Abstract:
To understand the enactment of Education for Sustainable Development (ESD) in higher education institution (HEI) and why very unequal ESD activity that mostly focused on campus greening rather than on pedagogic reform in HEI requires more than simply an examination of the ESD curriculum and pedagogy. To grasp why and how ESD is implemented in a HEI, the contexts in which it was created and implemented should be considered. Systems structures that include the context of the phenomena can show how the interaction between various factors gives rise to the outcomes that can be observed at the event level which is the enactment of ESD at the HEI. This paper presents a finding of the case study concerning systems structure of ESD conducted at one Malaysia university. This study is explanatory and may give insight to understand ESD enactment in HEI especially in Asian and developing country context. The findings from this study demonstrate that the agents’/ lecturer’s individual systems and the organisational/university system are co-evolving with their environment. The changes in the environment, such as the accelerating sustainability crisis and global influence, are perceived by the lecturers as stimulating ESD enactment in the university. The university’s response to the sustainability agenda involves temporality and selection. This explained the university’s delayed response to the sustainability agenda, until sustainability agenda gained attention globally after the Brundtland Report in 1987.Despite the forces to adapt to environmental changes, within a system there is resistance to change. In this study, it included: the lecturers’ perceived lack of sustainability awareness; sustainability acceptance influenced by disciplines; limited financial support from the university; a compartmentalised education system; bureaucratic tensions; and lacking of teaching skills among ESD educators.
