  • Water covers two-thirds of the earth and has a great influence on the future existence of all human being. Thailand has extensive coastline and near shore water that contain vast biological and mineralogical resources. The rivers and canals can be found around the country especially in the Bangkok, which once called the Venice of the East. Autonomous underwater robot (AUR) will be soon a tool to help us better understand water resources and other environmental issues. This paper presents the design and basic control of a six-degree of freedom AUR "Chalawan", which was constructed to be used as a testbed for shallow. It is a simple low cost open-frame design, which can be modified easily to supports various research areas in the underwater environment. It was tested with a conventional proportional-integral-derivative (PID) controller. After fine-tuning of the controller gains, the results showed the controller's good performances. In the future, the dynamic model of the robot will be analyzed and identified. The advanced control algorithm will be implemented based on the obtained model.

  • A first step review is completed on the suitability of European designed wind turbines in an East Asia climate. Six parameters are chosen for detailed analysis of proper meteorological measures from flat, hilly, forested, coastal and offshore sites in West Europe and East Asia: mean wind speed, 10 minute mean wind speed distribution, turbulence intensity, wind shear, 3 second extreme wind speed and 10 minute direction change. All six parameters are assessed with a view for contrast with the wind turbine design standard IEC61400. The diurnal and seasonal variation, average and extreme values of each parameter are calculated where appropriate. Industry standard software and analysis techniques have been employed to assess the applicability of existing wind turbine design standards and design guidelines for the East Asian market.

  • To strength global competitivenss and raise reputation in times of globalization, the practical use and development of traditional culture which must be discriminated against other countries wedging their ways. The purpose of this study is, 1. Make the mutual relationship between globalization of Korean traditional clothing(Hanbok) and the strean of the international fashion clear. 2. Deduce a common primary fact through commonness of international great products and a success of globalization in Asian nations 3. Suggest a scheme for globalization of Korean traditional clothing from the flank of a design and a policy on the basis of analysis. The consequence of this study is, 1. In the situation that modern international fashion focused Re-Orienting Fashion, Korean traditional clothing-Hanbok is considered as the most priceless value of application for an effective design sauce to differentiate.2. The common point between International leading fashion brands and success of globalization of each Asian nation is to pursuit an effective marketing strategy through a proper harmony with a differentiated 'uniqueness' which is motivated from their tradition, a sense of modern trend reading, and a 'generality' which fits in their lige styles. In consequence, we must develop typical design factors to be connected directly with Korean traditional image from the flank of design, For this, the typical design factors need to be applied with grafting tradition and modern ideas, simplicity, convenience, fleshly senses, and youth.

  • The purpose of this study was to identify the impact of acculturation level and individualism/collectivism on shopping behaviors such as' informational influences, shopping orientations, and store patronage of Asian ethnic groups residing in the United States. A total of 129 Asian adults residing in North Carolina State of the U.S. completed questionnaires. Results showed statistically significant differences in responses to an informational influence (i.e., media source) and two shopping orientation subscales (i.e., shopping confusion in the Us. and personalized shopping) between low- and high-acculturated groups. A significant difference was found between the individualistic group and the collectivistic group on three shopping orientation subscales. Due to the potential importance of considering both acculturation and individualism/collectivism when looking at shopping behaviors, four groups were created by categorizing respondents on the basis of their acculturation level and individualism/collectivism scores. Comparison on shopping orientations and informational influences by four groups revealed statistically significant differences in response to two shopping orientation subscales and two patronage behavior subscales.

  • For the past years, there had been some environmental cooperation among East Asian countries to reduce air pollution emissions from China. However, the progress of cooperation has been under developed because of lacking financial support, poor design of planning, and weak economic incentives for the industries. In this paper, some practical approaches have been suggested. First, electric trade to make Asian Grid among countries will be good alternatives for the fossil fuel, such as coal, for China. Secondly, natural gas pipeline from West China to Siberian pipeline would change the whole energy mix in this area around 2010, Therefore, it is very promising area for the energy industries to involve in gas project and get rid of many institutional barriers from China. Lastly, environmental industry is growing fast in East Asian. In China, waste treatment and management, air pollution control, and water quality management are some promising areas for the future. Hence it is desirable for Korea, Japan and China to make a eco-fund or company to boost up environmental technology as well as environmental market size.

  • This paper describes the research and development of Walking Tractors and Tillage Implements for Phase I (1991-1992) . The project consists of : (1) the study and need for the development of the walking tractors for Thailand and other Southeast Asian countries ; (2) the comparison in the use of the walking tractors and their transmission systems that are made in Thailand and aborad : and (3) the design of future walking tractors for Asian farmers in developing countries. The design of the walking tractors is concentrated to provide the ease to farmers, especially the elderly and female which will play an important role in the future agriculture of Thailand due to the lack of manpower. In addition , the design of the walking tractors is also aiming for small-scale farmers, the majority that have limited land capital. The walking tractors consist of several components but the most important one is the " Transmission System" . Thus, the research is concentrated in the devel pment an design of the a new transmission system. The new machine , currently developed, is named after the Chulalongkron University as " Chular Walking Tractor " , model SPJS -60. The tractor uses a 6-7 horsepower diesel engine with three forward gears and one reverse gear. The tractor also uses the latest gearing technology so called planetary gearing system with steering clutches system that never been used in any earlier model. The advantages of the planetary gearing system are : (1) the final drive gear can be small, and can be designed to provide higher strength with less wearing resistance, (2) the system eliminates a shaft which is used in other systems, thus reduces the weight and the manufacturing cost . Furthermore, the Chular Walking Tractor has an additional power take off shaft that can be used or linked with other standard agricultural implements.

  • Background/Aims: Diabetes mellitus (DM) is widely considered to be associated with risk of cancer, but studies investigating the association between DM and prostate cancer in Asian countries have reported inconsistent findings. We examined this association by conducting a detailed meta-analysis of studies published on the subject. Methods: Cohort or case-control studies were identified by searching Pubmed, Embase and Wanfang databases through May 30, 2012. Pooled relative risk (RR) with its corresponding 95% confidence interval (95% CI) were calculated using the random-effects model. Subgroup analyses were performed by the study type. Results: Finally, we identified 7 studies (four cohort studies and three case-control studies) with a total of 1,751,274 subjects from Asians. DM was associated with an increased risk of prostate cancer in Asians (unadjusted RR= 2.82, 95% CI 1.73.4.58, P < 0.001; adjusted RR= 1.31, 95% CI 1.12.1.54, P = 0.001). Subgroup analyses by study design further confirmed an obvious association. Conclusion: Findings from this meta-analysis strongly support that diabetes is associated with an increased risk of prostate cancer in Asians.
