- PublicationApplication of the Culture of Thai Literary Art: A Teaching Strategy for Creative Writing(Chulalongkorn University Printing House, 2008)
; University of the Thai Chamber of Commerce. Journal Editorial OfficeThis paper aims to demonstrate the use of traditional poetry in teaching creative writing.To attract new generation studentsû interest in the beauty of poetic language, as well as toenable them to write creatively, teachers may make use of some traditional forms of poetryfrom Thai literary art and apply them to todayûs social context. The use of Phamee(a poetic riddle) and Klon Nirat (a traveling poem) as teaching media are the strategiesthat make the convention of poetic writing relevant to contemporary contents.2 114 - PublicationChemical Composition and Physico-ChemicalProperties of Chinese Water Chestnut(Eleocharisdulcis Trin.) Flour(Chulalongkorn University Printing House, 2008)
; University of the Thai Chamber of Commerce. Journal Editorial OfficeChinese water chestnut (Eleocharis dulcis Trin.) is one of the most popular ingredientsof various Asian cuisines. It is traditionally used as peeled corms. However, the flourprepared from the corms also finds its applications in some Chinese dishes. The objectiveof this study was to investigate the chemical compositions and some physicochemicalproperties of Chinese water chestnut flour. The flour samples of different particle sizes(60-, 80- and 100-mesh) were investigated for their microscopic structure, pH, color(CIE L* a* and b*), swelling power and water solubility. The thermodynamic properties ofthe flour samples were monitored using a Differential Scanning Calorimeter. The flour pastingbehavior was investigated using a Rapid Visco Analyzer (RVA) and, finally, the productionyield of the flour was calculated. It was found that Chinese water chestnut flour sampleswere high in amylose, especially the 100-mesh sample (32.75% amylose). The ScanningElectron Microscopy (SEM) showed that the flour sample with larger particle size wasmore likely to attach and form clusters when compared to that of smaller particle size.The pH values of Chinese water chestnut flour samples were in the range of 5.62-5.66.Chinese water chestnut flour was light yellow while the flour with larger particle size hadlower L* value than that with smaller particle size. Swelling power and water solubility of theflour samples increased with increasing temperature. Moreover, the flour sample with higherstarch content required more energy for gelatinization than that with lower starch content.The 60-mesh flour produced a gel with higher stability upon cooling than the 80- and 100-mesh samples, respectively. The production yield of Chinese water chestnut flour was65.41% on a dry weight basis.24 516 - PublicationInteresting Issues Relating to the Succession inLien of the Heirs Disinherited by the de cujusbefore the Death of the de cujus and theSuccession in Lien of the Heirs Excluded fromthe Succession after the Death of the de cujusWhen a person dies, his estate devolves on the heirs by statutory rights, called çstatutoryheirsé, or on the heirs who are entitled by will, called çlegateesé, as the case may be. Butif such heirs behave in an unworthy way vis-a$-vis the de cujus, and are still entitled tothe succession, it would appear to be unjust. Hence, the stipulations of the law thatsuch heirs shall be disinherited ipso jure on account of their unworthy behaviorsvis-a$-vis the de cujus, by being excluded from the succession under two circumstances,i.e. exclusion from the succession for having diverted or concealed the property or forunworthy behaviors vis-a$-vis the de cujus. The exclusion from the succession could occurboth before and after the death of the de cujus. If the exclusion from the successionoccurs before the death of the de cujus, there are provisions of the law that entitle thesuccession in lien of such heirs by the çdescendenté of the excluded heirs. But if theexclusion from the succession occurs after the death of the de cujus, the çdescendentéof the excluded heirs could also succeed by their right of succession in lien of theexcluded heirs. In the view of the author, there could be a problem of interpretation ofthe law if it is asserted that the çdescendenté of the excluded heirs could succeed bytheir right of succession in lien of the excluded heirs.
7 122 - PublicationDuty of Care Signatories in Digitally Signed Transactions and High Tech Theft(Chulalongkorn University Printing House, 2008)
; University of the Thai Chamber of Commerce. Journal Editorial OfficeThe use of technology not only creates a number of advantages, but also entails risksand liabilities. Individuals who apply the technology must realize not only the advantages,but also their shortcomings. One of many possible causes of inefficiency in digitaltechnology is the conduct of the signatories, relying parties, and certification authorities,as well as attacks by a third party. The acts of a third party, such as an impostor or ahacker, can be considered as offences in the use of digital signatures. The acts of stealingprivate key creation data may cause private key holders to sustain losses. Thefts can beinstigated by means of copying private signing key creation data, stealing a smart cardwhich contains a private key or hacking the signatoryûs computer hard-drive. Due to thehighly technical nature of cyber stealing or hacking, the act of copying or hacking privatekeys stored in the signatoryûs hard drive may not be so obviously noticed or tracked astraditional theft or intrusion. The lay signatory may be unable to realize whether hisprivate key has been copied or hacked. The standard of the reasonable man remainsapplicable in the use of digital signatures. A signatory is obliged to exercise due care aswould be expected from a reasonable man who is in the same circumstances to avoidunauthorized use, access, theft or compromise of his private signature creation data.The signatory is also required to know apparent risks that a reasonable man wouldhave known under a similar situation. High tech theft, however, is not an obviously apparentoccurrence and a reasonable man would not know about it.7 35 - PublicationFullerenes and Fullerene Derivatives in Properties and Potential Applications(Chulalongkorn University Printing House, 2008)
; University of the Thai Chamber of Commerce. Journal Editorial OfficeAfter the discovery of Fullerenes, the 60-atom clusters and large carbon-cage molecules,the attention of scientists and materials scientists has been attracted by the synthesesof new materials based on the family of Fullerene molecules. Many properties ofFullerenes are new and unusual. With a better understanding of their chemical andphysical properties, the fabrication of new materials for advanced applications hasemerged as a challenging possibility. As we know that Fullerenes are easily modified,using organic chemistry and special synthetic techniques, into other molecular structures,this makes them remarkably versatile. The versatility of Fullerenes gives them enormousapplications. This paper will review on Fullerenes and Fullerene derivatives properties,what is interesting about these çnewé carbon materials and how their unique propertiescan be utilized in potential applications. Applications of Fullerenes and Fullerenederivatives in areas such as semiconductors, superconductors, polymer-like materials,catalysts have been reviewed. In the medical field, the potential applications ofFullerenes and Fullerene derivatives include diagnostic or therapeutic agents, inhibitionof HIV-P, powerful biological antioxidants, antibacterial activity, and DNA photocleavage.18 32
