Opis:
The Malaysian government has encouraged public sectors to adopt innovation to create value added that will increase their wealth creation and to enhance their competitive advantage. There are many initiatives have been put forward to encourage the innovative activities, nonetheless, the efforts are rather less fruitful. Thus, this paper aims to discuss the challenges faced in managing non-technological innovation in the organization and suggest ways for improvement particularly in Malaysian public sectors. For that purpose, seven interviewees have been chosen to be interviewed using semi-structured questions from two categories; facilitator and implementer. Thematic approach is implemented to analyse the data collected. This study has identified three critical challenges, which include innovative culture, inadequate resources and lack of collaboration with other institutions.
Rząd Malezji zachęcał sektory publiczne do przyjmowania innowacji w celu tworzenia wartości dodanej, która zwiększy ich dobrobyt i wzmocni przewagę konkurencyjną. Podjęto wiele inicjatyw zachęcających do innowacyjnych działań, jednak uzyskane wyniki nie są najlepsze. Niniejszy artykuł ma na celu omówienie wyzwań stojących przed zarządzaniem pozatechnologicznymi innowacjami w organizacji oraz zaproponowanie sposobów na poprawę aktualnego stanu, szczególnie w malezyjskich sektorach publicznych. W tym celu wybrano siedem osób, z którymi przeprowadzono wywiady, z wykorzystaniem półstrukturalnych pytań z dwóch kategorii; moderator i realizator. W celu analizy zebranych danych wdrożono podejście tematyczne. W badaniu wskazano trzy kluczowe wyzwania, które obejmują innowacyjną kulturę, nieodpowiednie zasoby oraz brak współpracy z innymi instytucjami.

Opis:
Carboxymethyl cellulose (CMC) was used in the chemical reduction using sodium borohydride to yield dispersive nano zero-valent iron (nZVI) particles as reactive and stable adsorbents. CMC- -stabilized nZVI particles were characterized via UV-visible light spectroscopy, X-ray diffraction, dynamic light scattering, transmission electron microscopy, and specific surface area assisted using a probe ultrasonication dispersing tool at 50% amplitude power. High catalytic reactivity obtained in pseudo-first order reaction for Cr6+ (rate constant K1 = 0.0311 min–1) and pseudo-second order for Cu2+ (rate constant K2 = 0.0946 g·mg–1·min–1) indicated that colloidal stability of nZVI particles can be achieved with a stabilizer for the removal of toxic contaminants.

Opis:
This paper describes the effect of pod propulsor attachment to the existing Naval Vessel hull form which was designed for conventional propulsor in aspects of resistance and motion characteristics. These investigations were carried out on a 3.0 m model by experimental works in the towing tank 120m x 4m x 2.5m at the Marine Technology Centre (MTC), Universiti Teknologi Malaysia (UTM). The basis ship chosen for this study is Sealift class type MPCSS (Multi Purpose Command Support Ship). In this study, the design for the new pod propulsor is based on a proven design and scaled down to suit this type of hullform accordingly. This paper describes the resistance comparison between bare and podded hulls in calm water as well in waves. The seakeeping test for hull with and without pod in regular waves at service speed of 16.8 knots were carried out at wavelength to model length ratio, Lw/Lm between 0.2 and 1.2. The outcomes from this experimental works on hull with and without pod were compared.

Opis:
For optimum fusion splicing process of a photonic crystal fiber, the collapsing of the air holes at any photonic crystal fiber is the key point of either increasing or decreasing the total splice loss. In this paper, an experimental study has been carried out to investigate the relation between total splice loss or total fiber attenuation due to splice loss and the length of the collapsed region of the air holes. This is done by splicing ESM-12B photonic crystal fiber between two equal lengths of single mode fibers and measuring the attenuation at different arc times and arc powers. The results showed that the increase in the length of the collapsed air holes region results in higher loss, therefore, higher fiber attenuation.

Opis:
This study aimed to examine the influence of internal marketing on organizational commitment among Yemeni banks. The study adopted internal marketing factors comprised of different dimensions namely vision, development, rewards, empowerment and internal communication as the independent variable. Meanwhile, the dependent variable comprised of different dimensions of organizational commitment including normative commitment, affective commitment and continuance commitment. The study employed a survey questionnaire for data collection, distributed to 407 Yemeni banks. Data obtained was analyzed through the use of descriptive statistics and exploratory factor analysis. Additionally, the structural equation modeling was used for the data analysis. The obtained results showed that internal marketing significantly affected organizational commitment with the path coefficient value being 0.928, indicating that the employees’ organizational commitment among the banks is impacted by the internal marketing provided by the banks. With regards to the model fit, its examination showed that the value of fit statistics (CFI=0.99, GFI=0.98 and RMSEA=0.042), based on the results, internal marketing has a positive impact on organizational commitment at (p=0.026 p<0.01), indicating that the study hypothesis is supported. Lastly, the study contributed to the internal marketing factors and its positive impact on organizational commitment among Yemeni banks.
Celem niniejszego opracowania było zbadanie wpływu wewnętrznego marketingu na organizacyjne zaangażowanie banków w Jemenie. W badaniu przyjęto wewnętrzne czynniki marketingowe składające się z różnych wymiarów, a mianowicie wizji, rozwoju, nagród, uprawnień i komunikacji wewnętrznej, jako niezależnej zmiennej. Tymczasem zmienna zależna składała się z różnych wymiarów zaangażowania organizacyjnego, w tym zaangażowania normatywnego, zaangażowania emocjonalnego i zobowiązania dotyczącego kontynuacji. W badaniu, w celu zgromadzenia danych, wykorzystano kwestionariusz ankiety, dystrybuowany do 407 banków w Jemenie. Uzyskane dane zostały przeanalizowane za pomocą statystyk opisowych i analizy czynników rozpoznawczych. Ponadto do analizy danych wykorzystano modelowanie równań strukturalnych. Uzyskane wyniki wykazały, że marketing wewnętrzny znacząco wpłynął na organizacyjne zaangażowanie, o wartości współczynnika ścieżki wynoszącej 0.928, co wskazuje na zaangażowanie organizacyjne pracowników wśród banków pod wpływem wewnętrznego marketingu oferowanego przez banki. Jeśli chodzi o modelowe dopasowanie w badaniu, analizując wartość dopasowanych statystyk w oparciu o wyniki (CFI = 0.99, GFI = 0.98 i RMSEA = 0.042) wykazano, że marketing wewnętrzny ma pozytywny wpływ na zaangażowanie organizacyjne (p = 0,026 p < 0,01), tym samym potwierdzając, że badana hipoteza jest poparta. Wreszcie badanie przyczyniło się do analizy wewnętrznych czynników marketingowych i pozytywnego wpływu na organizacyjne zaangażowanie banków w Jemenie.

Background: The aim of this paper is to examine the relationship between the administration of leadership training programs and trainees’ motivation to learn. Self-administered questionnaires were distributed to collect data from junior army leaders in Peninsular Malaysia. Methods: A cross sectional method was employed in this study because it allowed the researchers to integrate the LTP literature, the pilot study and the actual survey as the main procedures to collect data. Beside a purposive sampling technique was used to distribute 300 self-report questionnaires to junior army leaders at the organization and the survey questionnaire data were analyzed using SmartPLS. Results: The results show that the ability of senior administrators to appropriately use a well-designed course content and select the right instructors to teach and facilitate trainees had enhanced trainees’ motivation to learn in the organizational sample. Conclusions: This study tested a conceptual schema developed based on the LTP research literature. The results of the confirmatory factor analysis showed that the instrument used in this study satisfactorily met the standard of validity and reliability analyses. Furthermore, the outcomes of the SmartPLS path model proved that course content and instructors’ roles were important predictors of trainees’ motivation to learn in the organizations.

In this work, ZnO films were prepared by drop casting technique. The films were deposited on quartz substrates under different annealing time (15,30,45 and 60 min.) at a constant temperature (800 °C). The optical properties were achieved by measuring the absorbance and transmittance spectra in the wavelength range (200-900) nm. It was found that the absorbance decreases while transmission increases as the annealing time increases, while the reflectance decreases as the annealing time increases. The optical measurements indicate the kind of transition which was a direct allowed with an average band gap energies lie between 3.3 eV and 3.54 eV with the change of annealing time.

Porous silicon (PS) has been fabricated by Photo-electrochemical etching. Porous silicon was anodized on n-type Si in light using a current density of 20mA/cm2 for 10 min. The porous structure formation was confirmed using XRD and AFM studies. The root mean square (RMS) roughness of the Porous silicon layer is found to be around 47.5 nm and the ten point height was 317 nm. The average of pores diameter was 419.98nm, and the grain growth is columnar with a (211) preferred orientation. The grain size of the PS was estimated from the Scherer's formula and found to be 73 nm. All the properties of the porous silicon layer, such as porosity and the thickness depend on the anodization parameters. The porosity (P) was approximately 77 %. The thickness of the layer formed during an anodization in constant current was 3.54nm in gravimetric method, while its value was 1.77nm by using the theoretical relation.

Opis:
Neural and sliding mode controllers are generally based on the principle of nonlinear dynamic inversion. This leads to control signals containing high frequency components. This can result in actuator rate limiting due to loss of phase at higher frequencies. Large control inputs, for example due to the saturation component of the sliding mode controller can also result in position saturation of the actuator. In this paper we show that by the introduction of suitable phase compensators and an antiwindup scheme the neuralaided sliding mode controller performance can be improved. A novel scheme is proposed for the cascaded feedback controller which addresses practical requirements of both state limiting and control surface saturation respectively.

Opis:
Interactions between road users, motor vehicles, and environment affect to driver’s travel behavior; however, frailer of proper interaction may lead to ever-increasing road crashes, injuries and fatalities. The current study has generated the green driver concept to evaluate the incorporation of green driver to negative outcomes reduction of road transportation. The study aimed to identify the green driver’s behaviors affecting safe traveling by engaging two research phases. Phase one was to identify the safe driving behaviors using Systematic literature review and Content Analysis methods. Phase one identified twenty-four (24) sub-factors under reckless driving behaviors cluster, and nineteen (19) sub-factors under safe driving practice cluster. Second phase was to establish the actual weight value of the sub-factors using Grounded Group Decision Making (GGDM) and Value Assignment (VA) methods, in order to determine the value impact of each sub-factor to green driving. Phase two resulted that sub-factors Exceeding speed limits (DB f2.2.) and Driver’s cognitive and motor skills (SD f1.2.2.) have received highest actual values, 0.64 and 0.49, respectively; ranked as the High contributor grade. Contrary, the sub-factors Age cognitive decline (DB f1.2.) and Competitive attitude (DB f1.2.), and Avoid gear snatching (SD f1.1.4.) have the lowest actual values; and ranked in low-contribution grade. The rest of the sub-factors have ranked in medium-contribution grade. The research also found out drivers’ personalities (included, physical and psychological characteristics) remains unaccountable and non-measureable yet in driver travel behavior assessment models. The study outputs would be used in development of Green Driver Index Assessment Model.

Opis:
Density and diversity of Fusarium species and other fungi associated with rhizosphere and rhizoplane of lentil and sesame plants at three different growth stages were investigated. Sixteen species of Fusarium were isolated from rhizosphere (13 species) and rhizoplane (11) of both plants studied. In lentil, 11 species were recorded from its rhizosphere (9 species) and rhizoplane (8). Fusarium species associated with lentil rhizoplane gave highest number of propagules at the first stage of plant growth while the ones of Fusarium associated with the rhizosphere produced the highest number at the second stage of growth. F. solani was the most common in the three growth stages. In addition, of two growth stages, F. culmorum and F. tricinctum were isolated from the rhizosphere while F. nygamai and F. verticillioides from the rhizoplane. The other species were recorded from only one growth stage of lentil plant. In sesame plants, rhizosphere yielded nine Fusarium species while rhizoplane gave only six from the three stages investigated. Stage I of sesame rhizosphere possessed the highest colony forming units of Fusarium. As the case for lentil, F. solani was the most common species in sesame rhizospere and rhizoplane. F. verticillioides and F. nygamai (in three different growth stages) followed by F. oxysporum and F. tricinctum (in two growth stages) were recorded using the dilution-plate and/or soil-plate methods from sesame rhizosphere soils. Rhizoplane Fusarium species of sesame plants were isolated at the three different growth stages with almost equal number of colony forming units. F. poae came after F. solani in its frequency since it was recovered from two growth stages. Several of the isolated species are well-known as pathogens to many cultivated plants. To the best of our knowledge, three species are recorded here for the first time in Egypt from the rhizosphere (F. acutatum), rhizoplane of sesame plants (F. longipes) and from rhizosphere of both lentil and sesame and rhizoplane of lentil (F. nygamai).

Opis:
Understanding a membrane’s morphology is important for controlling its final performance during protein immobilization. Porous, symmetric membranes were prepared from a polyvinylidene fluoride/N-methyl-2-pyrrolidinone solution by phase inversion process, to obtain membrane with various microsized pores. The concentration and surface area of aprotein dotted on the membrane surface were measured by staining with Ponceau S dye. The dotted protein was further scanned and analysed to perform quantitative measurements for relative comparison. The intensity of the red protein spot and its surface area varied depending on the membrane pore size, demonstrating the dependence of protein immobilization on this factor. The membrane with the smallest pore size (M3) showed the highest protein spot intensity and surface area when examined at different protein concentrations. An increase in the applied protein volume showed a linearity proportional trend to the total surface area, and an uneven round dot shape was observed at a large applied volume of protein solution.

Opis:
Traditionally, pavement distress evaluations were carried out by visual observation. Traditional practice requires a person to walk along the stretch of the pavement to conduct distress survey, take photo and measure defects occurred at deteriorated surfaces. However, this approach is too subjective, generates inconsistencies of information, less reliable and time-consuming. Due to these shortcomings, the transportation practitioners in pavement maintenance seek for other alternative tools and techniques to arrest incapability of traditional practices. One of the tools available in the market is Ground Penetrating Radar (GPR). GPR is a geophysical tool known by ability to accommodate extensive data in pavement assessment, geotechnical investigation and structural assessment. The application of GPR is such new to most of road maintenance industry in Malaysia. Therefore, this study has been undertaken to evaluate the benefits of using GPR imaging and its application in assessing pavement structures in Malaysia. The GPR survey was conducted in Meranti street located at UTM (Universiti Teknologi Malaysia) campus, and then analyzed using REFLEX 2D simulation software. The finding shows there are three (3) types of information obtained from GPR survey included; identification of raw image and processed image, identification of pavement segments thickness, and identification of GPR response towards surface and subsurface conditions, which illustrated in radargram images. Furthermore, the GPR can perform at high speed and can save time. It is also beneficial for long-term investment due to ability to provide extensive information at a greater depth. The research indicates that interpretation of GPR’s radargram images consumes time due to the low resolution. Therefore, selection of GPR system is subject to level of accuracy and clarity of radar images needed in a project.
