Web Access Analyser for Distance Education Environment

Distance Education implementation has been greatly influenced by the changing of the current sophisticated technologies. Internet and World Wide Web (WWW) have enabled the rapid growth of distance education technology. The Internet is a huge database that connects most of the information source centers worldwide. This technology is equipped with the existence of WWW that ease accesses to the sources. With these technologies, distance education can be implemented properly. An approach been developed is the implementation of distance education through WWW. Learning modules are kept in a Web server while the student can access the modules from scattered terminals linked to the server via the network. It is a method of module delivery to the students that which are easier and faster. Even though distance education requires individual capability to manage the time and learning effort, the educators still have the responsibilities in evaluating their students' achievements. It is easier to evaluate on-campus students compared to distance learners. If the educators can evaluate on-campus students through their attendance and work performance, an appropriate approach to evaluate out-campus students' effort and commitment is necessary. There is a file that is specially created by a Web server which keeps and lists all access requests and transaction information made to the files kept within the server. This particular file is known as an "access_log" file. There has been a substantial effort to manipulate the file, for example, this study used "access_log" file to filter out information to produce students' distance module access statistics which is able to assist distance educators to evaluate distance students' commitment as well as to measure modules' design efficiency

Re-mining item associations: methodology and a case study in apparel retailing

Association mining is the conventional data mining technique for analyzing market basket data and it reveals the positive and negative associations between items. While being an integral part of transaction data, pricing and time information have not been integrated into market basket analysis in earlier studies. This paper proposes a new approach to mine price, time and domain related attributes through re-mining of association mining results. The underlying factors behind positive and negative relationships can be characterized and described through this second data mining stage. The applicability of the methodology is demonstrated through the analysis of data coming from a large apparel retail chain, and its algorithmic complexity is analyzed in comparison to the existing techniques

Newton Polyhedral Method of Determining p-adic Orders of Zeros Common to Two Polynomials in Qp[x, y]

To obtain p-adic orders of zeros common to two polynomials in Q [x,y], the combination of P . Indicator diagrams assodated with both polynomials are examined. It is proved that the p-adic orders of zeros common to both polynomials give the coordinates of certain intersection points of segments of the Indicator diagrams assodated with both polynomials. We make a conjecture that if ( A, IJ. ) is a point of intersection of non-coinddent segments in the combination of Indicator diagrams associated with two polynomials in Q [ x,y l then there exists a zero (L Tl) common to both polynomials such that ord ~. = A , ord Tl::: IJ. . A special case of this conjecture is proved

A Correlational Study of Achievement Motivation and Pupils' Performance in the Standard Five Assessment Examination From Selected Schools in Selangor

The performance of pupils in the Primary Five Assessment Examination was examined in relation to a number of variables namely achievement motivation, socio-economic status, intelligence, area of residence, school milieu and parental encouragement to assess the correlation between them. The subjects were 90 pupils selected from 40 primary schools in Selangor and represented the Chinese, Malays and Indians. Individual interviews were conducted by the researcher. Subjects were asked to answer questionnaires, the Thematic Apperception Test, and the Raven's Progressive Matrices. The results showed that achievement motivation correlated highly with performance in the stated examination. The other variables which showed significant correlations with performance were socio-economic status, intelligence, school milieu and parental encouragement

Estimation of occupational accident and accident prevention cost in wood based related industries.

The objective of the study is to estimate occupational accident cost in manufacturing industries, especially in wood based related industries. The study attempts to identify, define, and classify the cost components of occupational accident related cost and to catalogue the various economic approaches used to estimate the entire costs of occupational accident and to propose the risk prevention plan. The study uses local specific approach by reviewing company historical records on occupational accident as reported in JKKP 6, JKKP 8, JKKP 9 and company internal investigation reports. For each occupational accident, the site safety officer in charge, human resource and account employee, supervisor, victim, related co-workers and relatives were interviewed in order to estimate direct costs, indirect costs, prevention costs and others personal cost related to the accident. Other related information such as personal data of the victim, type of injuries, location of injuries and cause of injuries were recorded. A total of 24 occupational accidents data for the past five years were analyzed in the cost of accident summary report to determine the overall ratio of direct to indirect cost and ratio of total cost of accident to prevention cost. Further analysis was carried out to determine the most significant cost of accident related to demographic profiles for Malaysian and Non Malaysian employees. Result obtained from the analysis has been integrated into existing Hazard Identification, Risk Assessment and Risk Control (HIRARC) format during the risk assessment in the selected manufacturing process within the company. The estimated potential cost of accident and cost of prevention was added to the existing report for HIRARC. In conclusion, this study has determined the ratio of direct to indirect cost of occupational accident and to propose the risk prevention plan with additional information on cost of accident and cost of prevention

The Application of DNA Molecular Marker Techniques in Hevea Brasiliensis

DNA was extracted from several Hevea sources; namely, various Hevea species, several cultivars from within the Hevea brasiliensis species such as clones and in vitro cultured H. brasiliensis. Four DNA molecular marker techniques were used to analyze the DNA. These techniques included a hybridization-based marker technique called restriction fragment length polymorphism (RFLP) and three polymerase chain reaction (PCR)-based techniques viz. random amplified polymorphic DNA (RAPD), DNA amplified fingerprinting (DAF) and sequence-tagged microsatellite sites (STMS). In the RFLP study, a wheat ribosomal DNA, pTa71 (rDNA) probe was able to detect a reduction in rDNA loci number in DNA from in vitro cultured plants compared to DNA from control plants. Hybridization with M13 DNA fragments revealed interand intraspecific variations among the DNA samples. Neither of thesehybridization probes could detect somac1onal variation within a sample of in vitro cultured plants. On the other hand, RAPD and DAF were able to detect somaclonal variation within the in vitro cultured plants. The polymorphic patterns produced by RAPD could be neither correlated with any particular morphological trait nor the source of calli i.e. anther or ovule. Meanwhile, DAF proved to be more sensitive as it was able to detect a high degree of variation in the DNA extracted from anther derived calli. STMS could not detect any variation nor insertion/deletion mutation at the HMGR-l gene within the in vitro culture DNA. RAPD and DAF molecular markers were found to be dominant while RFLP and STMS markers were co-dominant in all of the H brasiliensis crosses tested in this study. No change in the methylation sites for both in vitro culture and control plants were detected when the DNAs were digested with both isoschizomeric restriction enzymes Hpall and MspI. A micro satellite enriched library was constructed and was found to be enriched with (GA)n repeats (39%). Hybridization with one of these clones revealed inter- and intraspecific variations with DpnII -restricted DNAs. This clone was subsequently sequenced and found to be an imperfect repeat

The Predıctıve Power Of Ego States On Burnout In Student Teachers

Bu çalışmada öğretmen adaylarında tükenmişlik ve ego durumlarının ilişkisi ve ego durumlarının tükenmişliği yordamadaki rolü incelenmiştir. Çalışma tarama modelinde betimsel bir araştırma niteliğindedir. Araştırmaya Pamukkale Üniversitesi Eğitim Fakültesi’nde farklı bölümlerde öğrenim gören 332 üçüncü (n = 110) ve dördüncü (n = 222) sınıf öğrencisi katılmıştır. Katılımcıların 90’ı erkek, 242’si kızlardan oluşmuştur. Veri toplama araçları olarak Maslach Tükenmişlik Envanteri ve Ego Durumları Ölçeği kullanılmıştır. Verilerin analizinde değişkenler arasındaki olası ilişkileri belirlemek için Pearson korelasyon katsayısı ve ego durumlarının tükenmişliği yordama gücünü belirlemek için de basit regresyon (linear) analizi teknikleri kullanılmıştır. Bulgular, duygusal tükenmişliğin eleştirel ebeveyn, altın çocuk ve asi çocuk ego durumları ile pozitif, koruyucu ebeveyn ve yetişkin ego durumları ile negatif; duyarsızlaşmanın eleştirel ebeveyn, doğal ve asi çocuk ile pozitif, koruyucu ebeveyn ve yetişkin ile negatif; düşük kişisel başarının ise koruyucu ebeveyn ve yetişkin ile negatif yönde ilişkili olduğunu göstermiştir. Ayrıca yapılan regresyon analizlerinde eleştirel ebeveyn, yetişkin, altın ve asi çocuk ego durumlarının duygusal tükenmişliği; eleştirel ebeveyn, yetişkin ve asi çocuk ego durumlarının duyarsızlaşmayı; yetişkin ego durumunun ise düşük kişisel başarıyı anlamlı olarak yordadığı görülmüştür. Bu sonuçlar, ebeveyn çocuk yetiştirme tutumları, eğitim ortamlarının niteliği, programların etkililiği ve eğitimcilerin iletişim yeterlikleri bakımından önemli ipuçları sunmuştur. Araştırmada elde edilen bulgular eğitimciler açısından tartışılmış ve önerilerde bulunulmuştur
