However, such improvements are inadequate compared to the overall development of sports at international level. In recent years sport is getting more and more influential and it will continue to grow in importance, even for developing countries. Recent developments have witnessed the use of sports facilities as a force for urban growth. The aim of this research is to explore the existing sports facilities in Kuala Lumpur federal territory developed by Kuala Lumpur City Hall (KLCH). Further to examine their impacts through managers' perception. The research argues that there is a relationship between capacity, location, type and opening year of the sports facilities and their impacts to the surrounding. It is also able to rank all the sports facilities according to their type.","PeriodicalId":236344,"journal":{"name":"2010 International Conference on Science and Social Research (CSSR 2010)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124933357","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}

Following the mathematical proof, it can be seen that using CRT index scheme proves the resulting DFT matrix in possession of cocyclic property. By exploiting the close relationship of successively lower order DFT matrices, a fast construction approach for general cocyclic DFT matrices is described in simple way. The proposed construction algorithm is presented for simplicity and clarity for it only minimally related to sparse matrices. The result indicates the presented fast algorithm performs quite well at decreasing the computation complexity.","PeriodicalId":236344,"journal":{"name":"2010 International Conference on Science and Social Research (CSSR 2010)","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125239837","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}

Minato motor is one of the unidirectional energized BLDC motors. Recently, bidirectional energized BLDC motor is being mainly studied. However, controlling the direction of the torque by each armature winding for unidirectional motor system is easier. Therefore, the authors developed a high efficient unidirectional energized BLDC motor. Asymmetric H-bridge circuit is used as a driver circuit for the proposed motor. This circuit is hard to break down, compared to the inverter used in bidirectional energized BLDC motor. During high speed rotation, undesirable armature current, which has deceleration characteristic, is generated. This current lowers the efficiency of motor. In this paper, the authors proposed measures for this solution in the proposed motors. The authors show the proof through the equations of copper loss ratio for Minato motor and proposed motors. The “3rd motor” which has the highest efficiency was discovered during examination of the equations.","PeriodicalId":236344,"journal":{"name":"2010 International Conference on Science and Social Research (CSSR 2010)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131781093","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}

At the core, the survival and competitiveness of the industry depend largely on the workforce. It seems obvious that hospitality management schools are now playing a critical role in providing support for the unprecedented development of the industry. This will depend largely on how educational institutions conceptualise hospitality management education. In order to identify the knowledge domain of the industry, the initial competence statements were drawn, adapted and collated from various studies. Industry professionals were identified using the Tourism Malaysia database on Malaysian hotels. The actual return was 132 or 39% of the 337 questionnaires sent. Eleven (11) factors were clearly defined. The result from the factor analysis has produced 11 underlying dimensions representing the 104 statements.

However, the present accounting system was designed to account for the tangible assets rather than the intangibles. Hence, IC may not be captured and reported by most firms. This paper explores the importance of IC to Malaysian SMEs and the types of IC information deemed important to them. A postal survey with the aid of a questionnaire was carried out. IC information was found to be relevant to SMEs in Malaysia. Intangible resources are regarded as important as the tangible ones. SMEs have often considered IC when defining strategies. Consequently, more specific IC information needs to be communicated in the annual reports. Guidelines on IC reporting should benefit SME managers and decision makers.","PeriodicalId":236344,"journal":{"name":"2010 International Conference on Science and Social Research (CSSR 2010)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122322695","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}

Environmental health indicators were reviewed and selected for this study with Kuala Lumpur city as case study. Environmental health was defined as “human health and disease” that are determined by factors in the environment and “environmental conditions” which affect the quality of health. In this research, ambient air quality level of the city and the air related health condition of residents were analysed. In this case study, the relationship between urban landuses, air quality and air related health were examined and were found to have strong and significant relationships, even though, air pollution is a trans-boundary issue. Results from the research have shown that city landuses and traffic generation in a city affect the air quality level (number of unhealthy days as measured in API) and its residents' health.","PeriodicalId":236344,"journal":{"name":"2010 International Conference on Science and Social Research (CSSR 2010)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131243570","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}

Bamboo plants normally occur in both primary and secondary forests and are considered fast growing, and high yielding renewable resources. They belong to the family of Gramineae and sub-family of Bambusoideae. Currently, there is lack of information on bamboo species composition in Pahang National Park, Malaysia. This information is useful for many relevant agencies involve in the management and conservation of non-timber forest products. The objectives of this study are to determine the composition, distribution pattern and diversity of bamboo in Kuala Keniam. Field sampling for data collection was conducted at three locations in the study area. The data collected in this study include the species, diameter at breast height (DBH), height, number of culms, size of clump and internodes length. A total of five species of bamboo occur in this area. These are Gigantochloa scortechinii (Buluh semantan), Schizostachyum brachycladum (Buluh lemang), S. latifolium (Buluh nipis), S. grande (Buluh semeliang) and Bambusa vulgaris (Buluh aur). From the field measurement, it was found that the means of DBH, height, number of culms, size of clump size and internodes length of bamboo are 5.3 cm, 10.9 m, 33 culms, 7.0 m, 49.2 cm, respectively. The Shannon-Weiner index of bamboo in this area was relatively low (1.07). Data obtained in this study could complement the conservation efforts not only for bamboo, but also for the overall species diversity in the area.","PeriodicalId":236344,"journal":{"name":"2010 International Conference on Science and Social Research (CSSR 2010)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134231351","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}

Measurements involve in the study are weight/mass for ordinary items (general weight), weight for valuable metals and volumes to measure rice that represent weight. This study revealed from the literatures that have been looked into five general unit measurements on weight, eleven on weight for valuable metals and seven on weight as measured by volume of rice. Most of the measurements have been quantified since some of them are similar with the terms used in the common Malay culture. By comparing the quantity among the measurements, a system for weight measurements is constructed. The objective of this study is to retain the Malay Minangkabau culture as a historical knowledge and heritage while uplifting the Malay language in the field of mathematical sciences in this country. Nevertheless, there is still room for further studies since the list of measurements is perhaps not comprehensive and emphasis should be placed on the origins of the words being used in the measurement (etymology).","PeriodicalId":236344,"journal":{"name":"2010 International Conference on Science and Social Research (CSSR 2010)","volume":"12 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134526367","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}

Materials and Methods: Miswak sticks were grounded to fine powder and then ethanol and aqueous extraction were formulated. Chlorhexidine (Oradex) mouth wash used as positive control and sterilized distal water used as negative control. Dental biofilm bacteria investigated including Eikenella corrodens, Streptococcus constellatus, Streptococcus sanguis, and Streptococcus salivariu. All bacteria cultured in Brain Heart Infusion (BHI) agar. Single pure colonies of bacteria were transferred into fresh BHI broth and incubated overnight. Bacterial counting was done by using Colony Forming Unit (CFU). Antibacterial activities were determined using bacteria grown on Mueller Hinton II agar by Minimum Inhibition Concentration (MIC) test and Minimum Bactericidal Concentration (MBC) test. Bacterial morphological alterations following treatment with Miswak extracts, Oradex and distilled water investigated under Scanning Electron Microscope (SEM) at 3500x, 10000x and 20000x magnifications. Results: MIC tests showed that Miswak ethanol extract mouthwash only require 25%w/v to inhibit growth of a fixed amount (0.2ml) of bacteria S.constellatus, S.salivarius and E.corrodens while S. mutans and S.sanguis only require 15% w/v Miswak ethanol extract to inhibit its growth, while aqueous extract at 50% w/v concentration did not inhibit any bacterial growth. MBC results revealed that 50% w/v ethanol Miswak extract mouthwash inhibited 100% of bacteria growth. However, 50% w/v aqueous Miswak extract mouthwash inhibited 20–60% of the bacterial growth. Under SEM ethanolic extract of Miswak and Oradex produced obvious alterations to the bacterial morphology while no changes were observed after treatment with aqueous Miswak extract. Conclusion: Miswak ethanol extract has stronger antibacterial action against periodontal pathogenic bacteria, it can be proposed as a good alternative mouthwash to control and inhibit periodontal pathogenic bacteria.","PeriodicalId":236344,"journal":{"name":"2010 International Conference on Science and Social Research (CSSR 2010)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130831190","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}
