A study of water-mist recirculation system for filtration and cooling effect in the kitchen hood ventilation system
Water-mist spray system in several heavy-duty kitchen hood canopies are
installed to efficiently control the high heat loads and grease emissions produced
from the cooking process and for safety purposes. Cold water is used in the water�mist system and work as a mist curtain inside the exhaust plenum of the canopy. The
main purpose of this study is to reduce the water consumption by introducing the
water-mist recirculation system to replace the current method water-mist system since
it is working as water loss. A standard ASTM 2519 and UL 1046 full-scaled
experiment was developed in the laboratory. An existing Halton Europe/Asian water�mist operating system was adopted in this study. Twelve (12) cycles (at 24 hours
water-mist activation) has been studied to determine the maximum water-mist
activation cycle. The data was collected at two (2) hours water-mist activation at
every water-mist recirculation cycle. The water-mist spray fluids viscosity is 0.7 cP
from fresh water until the 4th cycle (8 hours water-mist spray) and increase 14.29%
(0.8 cP) at 5th cycle to 12th cycle. On average, the difference in gas emissions
percentage for CO concentration between fresh water until 4th cycle is 10.81 –
18.92% while the CO2 concentration is 12.33 – 18.22%. On average, the difference in
cooling effects percentage for ducting temperature between fresh water until 4th cycle
was 5.55% while the hood temperature was 2.33%. From the study, the water-mist
recirculation system could save up to 611,667 liter per year and 466,798.5 liter per
year water for all U.S, European, and Asian kitchen hood designs per hood length. By
adopting the new water-mist recirculation system to the current water-mist kitchen
hood, the water operational cost for water successfully reduced to RM 4,889.63 per
year and RM 6,977.86 per year for U.S design and European or Asian design per
hood length respectively. The water-mist recirculation system has great potential to
improve the current water-mist system for the commercial kitchen hoo
Characterization and biodegradation of poly (vinyl alcohol)/cassava starch
A series of poly (vinyl alcohol)/cassava starch (PVA/CS) blends at 50, 60, 70 and 80 wt.% cassava starch contents were prepared in one-step compounding process. One step compounding means, all blends were compound together without solely plasticized PVA or cassava starch at beginning. All blends were characterized and testing accordingly. In this research, comparison between one-step compounding and two-step compounding (plasticized PVA/CS at the beginning) were tested by tensile strength. It shows that their tensile strengths were comparatively higher than the two-step compounding process of PVA/CS blends. In term of impact test, it indicates that CS acts as non-reinforcing filler. The compatibility of PVA/CS represents the similarity functional group and possess same polar group. Studies on thermal stability and crystallinity shows, increasing the cassava starch loading in PVA matrix, has reduced the enthalpy of melting point as well as degree of crystallinity. The onset degradation had shifted to a higher temperature when a higher percentage of cassava starch was used in PVA matrix. This is due to cyclic hemiacetal had been introduced into PVA blend by cassava starch. It resist to thermal attack. In biodegradability test, several factors have been determined to evaluate the rate of biodegradation. Increase the humidity as well as increasing the cassava starch loading in PVA matrix will improve the susceptibility contact of microorganism onto the surface of PVA/CS blend. Aspergillus Oryzae had been selected as a good reagent used to degrade the sample of PVA/CS blend compared to Bacillus Amyloliquefaciens and effective microorganism. The biodegradation process of PVA/CS blends in anaerobic condition is much more faster compared to aerobic conditions
The organizational implications of medical imaging in the context of Malaysian hospitals
This research investigated the implementation and use of medical imaging in the
context of Malaysian hospitals. In this report medical imaging refers to PACS,
RIS/HIS and imaging modalities which are linked through a computer network. The
study examined how the internal context of a hospital and its external context
together influenced the implementation of medical imaging, and how this in turn
shaped organizational roles and relationships within the hospital itself. It further
investigated how the implementation of the technology in one hospital affected its
implementation in another hospital. The research used systems theory as the
theoretical framework for the study. Methodologically, the study used a case-based
approach and multiple methods to obtain data. The case studies included two
hospital-based radiology departments in Malaysia.
The outcomes of the research suggest that the implementation of medical imaging in
community hospitals is shaped by the external context particularly the role played by
the Ministry of Health. Furthermore, influences from both the internal and external
contexts have a substantial impact on the process of implementing medical imaging
and the extent of the benefits that the organization can gain. In the context of roles
and social relationships, the findings revealed that the routine use of medical
imaging has substantially affected radiographers’ roles, and the social relationships
between non clinical personnel and clinicians. This study found no change in the
relationship between radiographers and radiologists. Finally, the approaches to
implementation taken in the hospitals studied were found to influence those taken by
other hospitals.
Overall, this study makes three important contributions. Firstly, it extends Barley’s
(1986, 1990) research by explicitly demonstrating that the organization’s internal and
external contexts together shape the implementation and use of technology, that the
processes of implementing and using technology impact upon roles, relationships
and networks and that a role-based approach alone is inadequate to examine the
outcomes of deploying an advanced technology. Secondly, this study contends that
scalability of technology in the context of developing countries is not necessarily
linear. Finally, this study offers practical contributions that can benefit healthcare
organizations in Malaysia

Malay, Chinese, and internet banking
Purpose: The purpose of this paper is to focus on the impact of cultural traits on the intention to use internet banking. Drawing from the technology acceptance model and trust literature, the paper examines the influence of perceived ease of use, perceived usefulness, and trust on the intention to use internet banking among Malay and Chinese ethnic groups. Design/methodology/approach: The questionnaire was distributed to final year business students and Master of Business Administration students at four public universities in Malaysia. A separate multiple regression was employed to analyze the data for each ethnic group. Findings: For both ethnic groups, the results showed that perceived usefulness, perceived ease of use, and trust, all have significant effect on the intention to use internet banking. Further examination of the regression coefficients revealed the cultural traits that may explain the extent to which they influence factors that affect the intention to use. Research limitations/implications: Respondents of this study were students. This factor may decrease generalizability of the study because students' interest on the use of internet banking may be different from those of the general public. One research implication of this study is that there is a need to consider the role of culture in examining factors that affect behavioral intention. Practical implications: Banks need to highlight the benefits of internet banking, make internet banking easy to use, and enhance internet banking's security to improve consumers' trust. Given the fact that culture affects one's behavior, each customer group needs to be evaluated differently and the "one-size-fit-all" approach to encourage internet banking usage should be avoided. Originality/value: This paper attempts to link cultural traits that may explain the extent to which it influences factors that affect the intention to use internet banking

Malaysia merupakan sebuah negara yang maju dan telah mencapai pembangunan sosioekonomi pada masa kini. Walau bagaimanapun, Malaysia masih menghadapi beberapa cabaran dalam menguruskan alam sekitar iaitu isu perubahan iklim. Isu perubahan iklim ini adalah isu alam sekitar pada masa kini yang semakin mendapat perhatian oleh masyarakat di seluruh dunia. Terdapat beberapa isu alam sekitar iaitu hujan asid, penipisan lapisan ozon, pemanasan global, dan pencemaran air. Isu alam sekitar ini semakin berleluasa di seluruh dunia dan semakin ramai institusi serta individu cuba untuk menangani masalah ini (Cordano et al., 2010)
Advertizing, concentration and profitability in Malaysian manufacturing revisited: A simultaneous equation approach
The original Structure-Conduct-Performance (SCP) paradigm that postulates a unidirectional relationship between concentration, advertizing and profitability had been used as the theoretical framework for many empirical works in industrial organizations before the mid seventies. Thereafter, doubts had begun to surface over the unidirectional postulate and there is new theory suggesting simultaneous interdependence. Unfortunately, not only are
Malaysian studies in this area few and far between (exhaustive literature review yields only three published studies namely, Gan and Tham, 1977; Gan, 1978; and Rugayah, 1992), they also failed to incorporate the more recent
theoretical development on the simultaneity of effects. This paper revisits the SCP paradigm as applied to the relationship among concentration, advertizing and profitability by conducting an empirical test that allows for simultaneous interdependence among variables. A set of three equations was estimated using three stage least squares (3SLS). The results provide considerable support to
the feed forward and feedback effects between the three variables. Advertizing intensity exerts a significant influence on profit and concentration in the industry and there exists a feedback effect running from concentration to
advertizing intensity. This finding suggests that advertizing does have an anti-competitive impact on the industry and therefore has a direct bearing on competition policy analysis
Forecasting of water intake and supply in water plant in Johor
The safety and availability of water are important for public health, domestic use, food, and drink production process. Since water is essential in daily life, the demand for water intake and water supply are increasing. Moreover, it must be ensured that the water intake is sufficient to supply water towards the consumers. This is vital to avoid water scarcity in society. Thus, the main objective of this research is to forecast the water intake and water supply by adopting exponential smoothing and Box-Jenkins methods. Then, the forecast performance is evaluated by using mean error (ME), mean absolute scaled error (MASE) and mean absolute percentage error (MAPE). Further, the best model is used to forecast water intake and water supply for the next seven days. The daily data for three years of water intake and water supply in one of the water plants in Johor was collected. The forecast capabilities of the two different methods were compared. Both methods are fitted well but, in overall, the triple exponential smoothing method is outperformed compared to the Box-Jenkins method. This is due to the exponential smoothing method to produce less MAPE and ME values. Both datasets shared the same model which imply the water treatment system used is stable and in good condition. Besides, the water intake and water supply by using triple exponential smoothing method is predicted to be decreased in the following seven days
