The samples were characterized using X-Ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) to analyze the present of TiO2 and SiO2 compounds in the prepared samples. Meanwhile, UV-Vis spectrophotometer was used to measure the transmittance spectra of the thin films and the water contact angle was analyzed to determine the hydrophilic properties. XRD result revealed that the TiO2 xerogel was anatase phase after the calcination. As for SiO2 xerogel, the pattern of IR spectra demonstrated the formation of SiO2 network. Therefore, from these results, the TiO2 and SiO2 xerogels were successfully prepared. Besides that, surface morphology of prepared coating films were studied using Scanning Electron Microscopy (SEM). As expected for SiO2/TiO2 double layers thin film, SiO2 particles aggregates were randomly distributed on the surface of TiO2. Performance wise, the prepared coating samples were also shown a positive result of water contact angle analyses. This finding revealed that a SiO2/TiO2 double layers thin film has demonstrated hydrophilic property based on the 13.9° of contact angle achieved. Moreover, the light transmittance of this thin film at normally incident light can be reached up to 70%. Therefore, it can be summarized that SiO2/TiO2 double layers thin film demonstrated a hydrophilic surface in nature.","PeriodicalId":426671,"journal":{"name":"2012 IEEE Symposium on Humanities, Science and Engineering Research","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115664068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These isolates were used in a study to determine the best antimicrobial agent to inhibit their growth and finally help in eliminating rubber odor. Three antimicrobial agents of different concentration including Sodium hypochlorite, Chloroxylenol and Formaldehyde as well as HISKA® (the coagulant and density enhancer for rubber latex) were used for screening the bactericidal properties by Kirby-Bauer disc diffusion test. It was shown that the pattern of inhibition zone varied according to the microorganism tested and the antimicrobial agent used. From the results, 1.0% Sodium hypochlorite and 1.0% Formaldehyde showed the potential as odor eliminator and could be applied in rubber plantation factory in order to inhibit the growth of microbes during the storing of natural rubber before processing. The SPME/GC-MS analysis supported the results that Sodium hypochlorite and Formaldehyde possess the ability to inhibit the growth of microbes and furthermore will reduce the odor without affecting the physical properties of rubber.","PeriodicalId":426671,"journal":{"name":"2012 IEEE Symposium on Humanities, Science and Engineering Research","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117290375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The countries that are included in the sample are five ASEAN countries comprise Malaysia, Thailand, Singapore, Indonesia, and Philippines plus Japan, Korea, China, Taiwan, and Hong Kong and US countries. In this study, the data will be divided into two financial crises which are Asian financial crisis and global financial crisis which each is divided into three sub-periods namely the pre-crisis period, crisis period, and post crisis period. Methods of this study are correlation analysis, unit root test, Johansen's cointegration test and Granger causality test. The findings show that government bond yield markets are more related during post crisis period as compared to pre-crisis period for both Asian financial crisis and global financial crisis. The government bond markets are found to be less cointegrated among themselves. In terms of causality test, it can be argued that global crisis period seems to be more significant causality related as compared to Asian crisis period. There is a possibility that the government bond yield markets are more related in the later years as compared to the earlier years. Further, it can be argued that for markets that are less cointegrated, investors can enjoy long-run international diversification benefits by investing across these markets because they do not have a tendency to move together in the long run.","PeriodicalId":426671,"journal":{"name":"2012 IEEE Symposium on Humanities, Science and Engineering Research","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116368647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The procedure of CFPR are improved by adapting Centroid-Index as defuzzification operator, in order to represent the whole set of fuzzy numbers correctly. The CFPR requires only (n-1) pair-wise comparisons for n given criteria, where this situation prove that the increasing number of criteria will not exponentially increased the number of pair-wise comparisons in criteria weights determination process. The evaluation of alternative towards criteria is carried out and the ranking can be obtained by using Generalized TOPSIS method. This method introduced Up and Lo operators for the purpose of determining ideal and negative ideal solutions, that are adequate under fuzzy environment and satisfied the partial ordering relations. The implementation of this integrated approach is presented in the selection of best notebook for students, which involved two decision makers, four criteria and four alternatives. The proposed method can be used as an alternative procedure in solving multi-criteria decision making (MCDM) problems.","PeriodicalId":426671,"journal":{"name":"2012 IEEE Symposium on Humanities, Science and Engineering Research","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123712210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study also evaluates the relationship of firms' characteristics such as firm size, type of industry, type of auditor and profitability with intellectual capital disclosure (ICD) levels. The extent of ICD was measured by using content analysis method. The data was collected by reviewing the annual reports of 104 companies for the year 2009. The results show that among the three categories, the information under external capital category has the highest reporting record, followed by internal capital and finally the human capital category. The multiple regression analysis was conducted to investigate the relationship between firms' characteristics and ICD. The regression produces an adjusted R2 of 0.377 which indicate that the model is able to explain 37.7 percent of the variance in the dependent variable for the whole sample. The results show that type of industry and type of auditor has a significant association with the intellectual capital disclosure at 5% significant level. Finally, the other variables such as size and profitability did not have any significant association with the ICD. The results have significant implications for setting standard on the disclosure of intellectual capital information in the annual reports. It will give some insight to the policymakers towards the needs to design future accounting guidelines on ICD.","PeriodicalId":426671,"journal":{"name":"2012 IEEE Symposium on Humanities, Science and Engineering Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123191422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cement brick or sand brick made from sand mixed with cement and formed into rectangular cubes or hollow rectangular cubes. Cement bricks are generally used for the construction of houses or small buildings as it is cheaper and often used for a less loaded structures. Brick wall in building is considered to be an important component in the construction due to its high cost. In addition, extensive cement and brick production plants contribute to air and noise pollution. Material recruitment process on hill to make cement also cause geological and landslide problems. S+WPSA Brick using sand and Waste Paper Sludge Ash (WPSA) mixture are solid rectangular cubes designed to be a cheaper but with similar compressive strength to common bricks and can overcome all the problems. This paper illustrates an experiment study and investigates the results of pundit test, skid resistance test and compressive strength test of common brick and S+WPSA brick. S+WPSA Brick indicates a more homogeneous, less void and good in quality compared to clay brick and sand brick. Besides that, the S+WPSA Brick introduces smoother surface compared to the sand bricks and clay brick in the market. Clay brick recorded the highest compressive strength of 15.17 MPa when compared with S+WPSA brick of 5.287 MPa and sand brick of 1.76 MPa.","PeriodicalId":426671,"journal":{"name":"2012 IEEE Symposium on Humanities, Science and Engineering Research","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116156249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
