    In aerial photogrammetry, aerial photographs are acquired using aerial camera and light aircraft as a platform. The aerial photographs are usually processed for mapping such as for production of topographic map and other special purpose map known as thematic map. However, this method is expensive and suitable for large area but it is not practical for mapping small area. This study concentrates on the use of high resolution digital camera and a very light platform known as unmanned aerial vehicle (UAV) as data acquisition system in capturing digital aerial photographs. The acquired digital aerial photographs were processed using image processing software to produce digital map and digital orthophoto. The results showed that an accuracy of sub-meter can be obtained using the employed method. In Geographical Information System (GIS), it is quite common that topographic map and orthophoto are used as a base map. Hence, the findings from this study could also be used as an input for GIS. Not to forget, the photogrammetric technique could be used not only for mapping but it could also be used for any environmental protection and conservation

    Organic materials were previously used as insulators in electrical technology. These materials, however, are currently used as conductors once their photoconductivity is confirmed and studied. From the literature, it has shown that the photoconductivity of trimethyl phenyl diamine (TPD) increases in the air and decreased in the atmosphere of the vacuum. To the best of our knowledge, there is no detailed study of the effects of gas in the air that affect TPD photoconductivity. In this study we investigate the effects of nitrogen (N2) and oxygen (O2) gases on photoconductivity, degradation and residual decay of photoconductivity for thin film TPD. The results of the study show that in the atmosphere of O2, TPD produces about seven times higher photoconductivity compared to N2 conditions. It also shows that, N2 and O2 provide more effective response time during photoconductivity residual decay. Photoconductivity degradation occurs in all conditions and its recovery takes more than 65 hours

    The ideas introduced by Einstein General Relativity theory toward thedevelopment of wormhole research field are reviewed namely, theconcept of spacetime, Riemarxrian geometry, cosmological constantand the pioneering work of Einstein and Rosen on the subject.Spherically symmetric spacetime metric that provides the wormholespacetime metric by the revival works of Morris and Thorne arediscussed. Concerning recent works on the subject a generalizedwormhole solution with cosmological constant introduced by the worksof Lemos, Lobo and Oliveira are also discussed. Finally, the rotatingwormhole solution as introduced by Khatsynovsky and Teo hasprovided a more generalized solution compared with the Morris-Thornestafic solution. Based on these ideas, we proposed the spacetime metricof a slowly rotating spherically s)rynmetric wormhole where weconstructed set ofEinstein equalions in term ofpressure and the energydensity of the wormhole.Keywords; General Relatfuity; Cosmological constant; Einstein-RosenBridge; Wormhol

    The increase of dangerous drugs using cases, in Bangkinang affected the userdiscrete from the environment, family, society until country. The majority of dangerous drugsusers are adolescent in 11 until 19 years old. In the several time, a lot of adolescent useddangerous drugs because the minimum information that their gotten. There for, DWP, BNKand Polres Kampar held socialization in SMA Muhammadiyah Bangkinang to invite them foravoiding the drugs. The intention of this research is to know the socialization effect of thedangerous drugs to the student\u27s attitude of SMA Muhammadiyah Bangkinang.The researchdesign used kuantitative research by descriptive method. The account of sampel is 70people from 193 population. The sampel is decided from Quota Sampling technique, analyzemethod in this research used a formula P=F/N × 100%. The result of this research showsthat the socialization effect of dangerous drugs to the student\u27s attitude SMA MuhammadiyahBangkinang can be categoried good with the precentage is 95,09% and the socialization washeld by DWP, BNK and Polres Kampar to SMA Muhammadiyah Bangkinang was succesfull

    Reformation programs of education should be directed to the importance of character education that involves the government and is directed through strategic plan of the National Education Department that accesses the needs and demands of the modern world and adapt to global conditions of the modern world. The purpose of this study was to determine; (1) models Lesson Planning Design, delivery of Learning and the creation of quality learning, (2) the magnitude design factors of significantly contribute learning plan on quality learning, and (3) the magnitude of factors on design of real contribute learning plan to create quality learning, also (4) whether strong or not of design of learning plan and quality learning process that contribute to create high quality learning. Methods in this study uses survey data collection techniques based on the Quetioner and interviews.The results show that generally the respondents give an assessment "yet / not good" for the design of learning plan. From the results, correlation between learning processes and the creation of high-quality learning obtain that r-count of 0.672 > r-table 0.138 (dk = 238). There is a significant relationship between learning plan design with the creation of high-quality learning. Likewise, there is significant influence between learning process with the creation of high-quality learning. SPSS.17 show R2 of 0.640, as an index of determination that contribute to variable of learning plan design and learning process to create high quality learning.R2 of 0.640 states that 64% of learning plan design influence the creation of high quality learning, while the remaining 36% (100% -64%) is influenced by other factors that can not be controlled in this study

    The life and health challenges of young Malaysian couples: results from a stakeholder consensus and engagement study to support non-communicable disease prevention

    BACKGROUND: Malaysia faces burgeoning obesity and diabetes epidemics with a 250% and 88% increase respectively between 1996 and 2006. Identifying the health challenges of young adults in Malaysia, who constitute 27.5 % of the population, is critical for NCD prevention. The aim of the study was two-fold: (1) to achieve consensus amongst stakeholders on the most important challenge impacting the health of young adults, and (2) to engage with stakeholders to formulate a NCD prevention framework.METHODS: The Delphi Technique was utilised to achieve group consensus around the most important life and health challenges that young adults face in Malaysia. Subsequently, the results of the consensus component were shared with the stakeholders in an engagement workshop to obtain input on a NCD prevention framework.RESULTS: We found that life stress was a significant concern. It would seem that the apathy towards pursuing or maintaining a healthy lifestyle among young adults may be significantly influenced by the broader distal determinant of life stress. The high cost of living is suggested to be the main push factor for young working adults towards attaining better financial security to improve their livelihood. In turn, this leads to a more stressful lifestyle with less time to focus on healthier lifestyle choices.CONCLUSIONS: The findings highlight a pivotal barrier to healthier lifestyles. By assisting young adults to cope with daily living coupled with realistic opportunities to make healthier dietary choices, be more active, and less sedentary could assist in the development of NCD health promotion strategies<br/
