Tahap kepercayaan guru besar terhadap guru: Satu penilaian

Malaysia adalah salah sebuah negara yang memberi perhatian utama dalam pembangunan pendidikan dengan memberi kepekaan kepada pengurusan pendidikan yang berkesan serta kualiti dan profesionalisme guru. Bertitik tolak daripada aspirasi tersebut, kepercayaan pemimpin sekolah terhadap guru perlu dikenal pasti dalam usaha melihat sekolah mencapai kecemerlangan hasil jalinan yang positif antara pemimpin pendidikan dengan guru. Secara umum, kajian dilaksanakan adalah untuk menentukan tahap kepercayaan guru besar di sekolah kebangsaan terhadap guru berdasarkan Model Kepercayaan multi-dimensi oleh Tschannen-Moran (2004). Sampel guru besar untuk kajian ini telah dipilih melalui kaedah persampelan rawak iaitu 155 orang guru besar yang mewakili sekolah kebangsaan di seluruh negara. Kajian berbentuk tinjauan ini juga telah menggunakan soal selidik utama iaitu Principals Trust Inventory yang turut dibina oleh Tschannen-Moran yang telah diterjemahkan, dinilai ketekalan dalaman serta diubah suai untuk tujuan kajian ini. Secara keseluruhan, kajian mendapati bahawa tahap kepercayaan guru besar terhadap guru adalah pada tahap yang tinggi hasil maklum balas 154 orang guru besar. Penilaian tahap kepercayaan ini turut didapati tidak berbeza serta tidak mempunyai perkaitan dengan faktor latar belakang mereka

Mangrove mapping using Landsat imagery and aerial photographs: Kemaman District, Terengganu, Malaysia

Classification and distribution of mangrove vegetation are vital information for the proper development of a mangrove management plan. In this study, classification for the mangroves of the district of Kemaman were done using both 1 : 5000 aerial photographs and Landsat TM imageries. The coverage by aerial photographs is limited to the coastal and estuarine areas only. Thus, for areas further upstream of the aerial photo coverage, Landsat TM imageries were used. Analysis of aerial photographs and remote sensing images revealed that the mangroves of Kemaman could be classified into 14 different classes of vegetation. All the 14 classes were identified from areas covered by the aerial photographs. For areas covered by the Landsat images only 7 classes of vegetation were identified. The accuracy for aerial photograph and Landsat images are 91.2% and 87.8%, respectively. It can be concluded that although both techniques are useful in determining the mangrove vegetation classes, the large 1 : 5000 aerial photographs are more accurate and provided more detailed information comparatively

Particle Size Distribution in the Bottom Sediments of the Kemaman River Estuarine System, Terengganu, Malaysia

Surface sediment samples from the Kemaman River estuarine system were analysed for the grain size in order to understand better the sedimentation processes in the estuary and along the Kemaman river. Their statistical values do not vary significantly according to the seasonal changes but show some relatively lower phi (0) values during the non-monsoon season compared to the monsoon season. The characteristics of deposited sediments at each station are very dependent upon the combination of physical forces such as freshwater runoffs, tidal currents and waves

Accumulation of Barium, Uranium, Cadmium and Manganese in the Sediment Core from the Pulau Cik Wan Dagang Mangrove Forests, Terengganu, Malaysia

The accumulation of elements Ba, U, Cd and Mn with respect to depth was determined in a 150 cm sediment core obtained from the mangrove forests of Pulau Cik Wan Dagang, Kuala Kemaman, Terengganu, Malaysia. Generally, all elements except Mn decrease with depth and their vertical profiles show a clear boundary at about 70 cm deep. In order to assess the influence of heavy metal pollution more precisely, enrichment factors (EF) were calculated. In this study, U and Cd have EF values significantly greater than unity and may therefore be considered to be predominantly anthropogenic in origin whereas Ba and Mn which have EF values about unity are considered to be predominantly terigenous in origin

Psychometric properties of instruments measuring competencies of research support librarian and self-directed learning traits

Librarians who work professionally in libraries must make themselves visible in the processes surrounding academic research. These research support librarians need to equip themselves with relevant competencies to play their share in supporting learning, enhancing teaching, improving research, providing services as well as anticipating the needs of academic researchers. In order to investigate these competencies, it is imperative to scrutinise the self-directed learning among the librarians because many studies have agreed that self-directed learning has an influence on competencies. In this study, the researcher analysed the validity and reliability of Competencies of Research Support Librarian instrument and Self-Directed Learning Traits instrument. The bank of items was developed from the Core-Competencies for Twenty-First Century CARL Librarians Model and Knowles' Andragogy-Adult Learning Theory as well as from an exhaustive literaturere view. Experts from librarianship and test and measurement areas reviewed the instruments in order to establish face and content validity. Internal consistency and reliability were measured using Cronbach's alpha and Rasch model. Thirty research support librarians of a local comprehensive university and a research university scores were used. The reliability test resulted in an overall value of.94. The results of the study yielded how trustworthy and dependable the instruments are and the effectiveness of the instruments in investigating the influence of self-directed learning on the competencies of research support librarian. © Serials Publications

A study of caesar cipher and transposition cipher in jawi messages

Cryptography known as art and science which is used to hide the messages that contain a few policy terminologies. These terminologies in cryptography are plaintext/ messages, ciphertext, encryption, decryption and key. Encryption is a proses to transform the plaintext together with key into ciphertext. Decryption is the reverse process of encryption. Caesar cipher and transposition cipher are two historical ciphers in cryptography. Caesar cipher is a monoalphabetic cipher. It is a substitution cipher which replace each letter in plaintext with another letter to form the ciphertext. Transposition cipher uses a technique which rearrangement letters in plaintext with a keyword and produce the ciphertext. Caesar cipher and Tansposition cipher both are commonly used to encrypt the English letters. The output of encrypted of English letters are known as ciphertext. The attacker can easily cryptanalysed the Caesar cipher by observing the frequency distribution English letters and ciphertext. For Transposition cipher, the cipher can be cracked by knowing the keyword. To date, there is no any research encrypt Jawi letters using Caesar cipher and Transposition cipher. Hence, in this paper encryption and decryption by using Caesar cipher and Transposition cipher in Jawi messages are proposed. Next, the security level of Caesar cipher and Transposition cipher in Jawi messages are compared. The result has shown that both ciphers are still not secure to protect the confidentiality of the Jawi messages

Kansei for the Digital Era

For over 40 years, Kansei-based research and development have been conducted in Japan and other East Asian countries and these decades of research have influenced Kansei interpretation. New methods and applications, including virtual reality and artificial intelligence, have emerged since the millennium, as the Kansei concept has spread throughout Europe and the rest of the world. This paper reviews past literature and industrial experience, offering a comprehensive understanding of Kansei, the underlying philosophy, and the methodology of Kansei Engineering from the approach of psychology and physiology, both qualitatively and quantitatively. The breadth of Kansei is described by examples, emerging from both industry and academia. Additionally, thematic mapping of the state-of-the-art as well as an outlook are derived from feedback obtained from structured interview of thirty-five of the most distinguished researchers in Kansei. The mapping provides insights into current trends and future directions. Kansei is unique because it includes the consideration of emotion in the design of products and services. The paper aims at becoming a reference for researchers, practitioners, and stakeholders across borders and cultures, looking for holistic perspectives on Kansei, Kansei Engineering, and implementation methods. The novelty of the paper resides in the unification of authors amongst pioneers from different parts of the world, spanning across diversified academic backgrounds, knowledge areas and industries

Trace metals in surface sediment of the South China Sea, Area II: Sarawak, Sabah and Brunei

The trace metals composition of surface sediment of the South China Sea off Sarawak, Sabah and Brunei were measured. Total metal concentrations in the 63 µm fraction are reported in this study. For the pre-monsoon cruise, the metal concentrations ranged between 1.01 – 13.0 µgg-1 Pb, 8.28 – 99.8 µgg-1 Cu, 27.8 – 137.0 µgg-1 Zn, 10.1 – 75.7 µgg-1 Cr, 175 – 1166 µgg-1 Mn, 0.83 – 4.57% and Fe 0.16 – 2.25%. The range of metal concentrations measured in the post-monsoon cruise varied between 1.63 – 18.9 µgg-1 Pb, 7.52 – 38.0 µgg-1 Cu , 14.4 – 105 µgg-1 Zn, 19.6 – 87.6 µgg-1 Cr, 157– 1890 µgg-1 Mn, 1.37 – 9.83 % Al and 0.51 – 4.47 % Fe. The distribution of metals in the sediment showed different patterns between the pre-monsoon and the post-monsoon periods. The Rajang River seems to be one of the major factors affecting the distribution of metals in the seabed off Sarawak
