  • Game engine, materialized by a library or a shape of the module, is providing many ability for developing game. Because of the high cost of developing game, game engine plays a big role on game developing urea by how it provide it's efficiency. In other words, the message scheme, which occur often while carrying out the game, highly affect on how fast it manage, its efficiency, and system's efficiency. Also, it is one of the important urea that needed to be considered while developing the game engine. In this paper, we suggest managing the message scheme technique by Lua script language, proving its suggested technique by developing $O_2$ engine itself, and analyzing it's capacity in order to show its efficiency.

  • We have examined congenital malformation in developing chick embryo caused by endocrine disruptor, bisphenol A (BPA). We injected BPA into the air sac of developing egg on day 4 of incubation. BPA-treated group with a concentration of 10 ㎍/egg showed a little decrease on their body length compared to the untreated group. But the group treated with 50㎍/egg revealed severe malformation in eyeballs and bills. The group treated with 100㎍/egg could not continue their development after few days of incubation. These results indicate that BPA clearly inhibits the normal development in chick and it should be toxic to the developing fetus at early stage and in various tissues. The study should contribute to the understanding of toxic effect of BPA in developing human fetus when exposed to the BPA.

  • This paper proposes an R&D project selection methodology for green technology centered on developing country-oriented technology commercialization. Eight selection criteria are derived from the R&BD logic model : technology needs of developing countries, effectiveness of green technology, technological potentials, domestic technological capability, commercialization feasibility, economic benefits, business feasibility, and spillover effects of developing countries. 21 qualitative and quantitative indicators are then defined for each criterion. The analytic hierarchy process is conducted to produce relative importance of evaluation indicators and to set final priority scores of R&D project candidates. The working of the proposed methodology is provided with the help of a case study example of Green Technology Center. The proposed methodology is expected to be effectively utilized for policy practices of R&D project selection in the field of green technology.

  • Information and Communication Technology is now widely accepted by developing countries as a development tool in their efforts to alleviate poverty, enhance human development, and achieve Millennium Development Goals. Recognizing this untapped potential and development strategies incorporating ICT are being increasingly promoted and launched across the developing countries requiring a comprehensive ICT policy that plays a crucial rule, in particular, in the area of agriculture and rural development. While the potential advantages of ICT for development are enormous in developed countries, national policies of developing countries are yet to adequately reflect truly comprehensive and integrated strategies for harnessing and exploiting this potential. This paper tries to provide implication of ICT policy to the agriculture and rural development in developing countries, in particular through lessons learned from European Union (EU) IT policy. Through the examination of vital projects in the agriculture and rural development sectors and case study analysis of applied policies and strategies implemented in the European Union, this paper provides tangible examples and lessons for policy-makers and practitioners involved in the field. Hence, this study provides policy-makers the necessary tools, information and knowledge to facilitate the formulation and adoption of ICT policies and strategies in the agriculture and rural development sector.

  • Climate negotiations have been going on for the last two decades and the awareness for impacts of climate change has improved substantially. However, the trends of global $CO_2$ emissions did not reveal any encouraging signs, with developing countries emitting even more $CO_2$ and industrialized nations showing no signs of reducing emissions to below their 1990 levels. In order to meet the ambitious targets set by the Stern report for the next two decades, it is important to find new and path-breaking approaches to climate change. This paper attempts to analyze the use of carbon/development space historically, at present and in the future with a focus on equity. Trends analysis focuses on the last two decades (Post Rio) and the carbon budget based analysis considers a period of 1850-2050. Industrialized countries are found to have significantly overshot their budgeted allocation for the last 160 years. Both the developing and industrialized countries are overshooting the present budget estimates based on world per capita budget for the next forty years and proportional to the population of each country. It is important for the industrialized countries to bring down their emissions to meet their carbon budgets while the developing countries use their development space as a guideline for their development path. Furthermore, this paper presents aggressive and regressive scenarios for the industrialized countries to compensate for the climate debt they have created.

  • The unsteady heat release characteristics play a significant role in combustion instabilities observed in low emissions gas turbine combustors. Such combustion instabilities are often caused by coupling mechanisms between unsteady heat release rates and acoustic perturbations. A generalized model of the turbulent flame response to acoustic perturbations is analytically formulated by considering a distributed heat release along a curved mean flame front and using the flame's kinematic model that incorporates the turbulent flame development. The effects of the development of flame speed on the flame transfer functions are examined by calculating the transfer functions with a constant or developing flame speed. The flame transfer function due to velocity fluctuation shows that, when a developing flame speed is used, the transfer function magnitude decreases faster with Strouhal number than the results with a constant flame speed at low Strouhal numbers. The flame transfer function due to mixture ratio fluctuation, however, exhibits the opposite results: the transfer function magnitude with a developing flame speed increases faster than that with a constant flame speed at low Strouhal numbers. Oscillatory behaviors of both transfer function magnitudes are shown to be damped when a developing flame speed is used. Both transfer functions also show similar behaviors in the phase characteristics: The phases of both transfer functions with a developing flame speed increase more rapidly than those with a constant flame speed.

  • The substantial slowdown of economic growth since the global financial crisis of 2008-2009 is rekindling debate on whether developing Asia should use fiscal expansion to boost aggregate demand. A key factor in the debate is the effectiveness of countercyclical fiscal policy in the region. The global crisis, as well as the fiscal stimulus packages implemented by developing Asian countries at that time, give some clues to this important issue. The region weathered the global crisis well and experienced a robust V-shaped recovery. According to conventional wisdom, the fiscal stimulus packages put in place by Asian governments played a key role in the region's recovery. The central objective of this paper is to empirically test this wisdom by using cross-country panel data. Our main finding is that the stimulus has had a limited but positive impact on developing Asia's output during the global crisis. This lends some support to the notion that countercyclical fiscal policy can help the region cope with severe external shocks. The broader, more fundamental implication for regional policymakers is that the region's long-standing commitment to fiscal discipline can yield significant benefits beyond macroeconomic stability. An important consequence of this commitment - relatively healthy fiscal balance sheets - enabled the region's governments to quickly and decisively embark upon fiscal stimulus programs.
