The socio-economic and environmental systems of world are in turmoil. International conflicts are placed in their geographical context through the integration of maps. Changes in the world political map have often been the outcome of wars and conflicts associated with major geopolitical transitions. We identify five basic types--proto-nationalism, unification nationalism, separation nationalism, liberation nationalism and renewal nationalism. Political leaders in a wide range of contexts have been able to appeal to the nationalist doctrine to justify their actions. In recent years indigenous peoples have found a new voice in their struggle for survival. Although colonial empire's ending followed long and bloody struggles in some places. We really cannot understand the modem world as a whole if we do not understand the dynamic of that part of it which has endured and struggled against colonialism. The patterns of the international conflicting area are divided internal conflict type, mixed conflict type, international conflict type. The formation factors of the international conflicting area are divided ethnic group, religion, colonialism, resource, territory. There has recently been a resurgence of Islam's importance in world affairs. The oil crises of the 1970s gave new international leverage to several Muslim states.

Purpose - Ethical consumption is the action of buying one product over another with an ethical idea in mind. It has gained in popularity since the 1990s with more emphasis being put on the power of consumer actions to create social, economic, and environmental change. Ethical consumption involves boycotts of certain products or brands as well as purchases linked to ethical issues. Cause-related marketing (the buying behavior of ethical consumption) involves a for-profit and non-profit entity teaming up to promote a product at the same time as promoting a social cause. Each time a consumer buys that product, a donation is made by the for-profit entity to the non-profit entity supporting the specific cause. Cause-related marketing has become a tremendously popular type of ethical consumption in recent years owing to its reputation of allowing companies to "do well by doing good." This study examines how consumers' perception of cause and attitude influence their attitude toward a cause-related marketing campaign and attempts to suggest implications for marketers. Research design, data, and methodology - First, this study was designed to examine the consumers' perception factors (cause involvement, attitude for cause, attitude for company and brand familiarity) in order to determine whether these factors have significantly affected consumers' attitude toward a cause-related marketing campaign. Second, this study developed a structural equation model and tested it empirically using survey data from 223 individual respondents. Respondents were undergraduate students in Chungnam. They were shown an existing real campaign message of cause-related marketing, and then filled out a questionnaire. Data were analyzed with SPSS 20.0 and AMOS 17.0 programs. Results - The hypotheses were tested using factor analysis and structural equation modeling. The study's results showed that brand familiarity, attitude to the company and attitude to the cause significantly affected consumers' attitude toward the cause-related marketing campaign and performance. In particular, attitude to the cause was significantly related to attitude and performance of the cause-related marketing campaign. However, the hypothesis about cause involvement was not supported with the results indicating that cause involvement did not affect consumers' attitude toward the cause-related marketing campaign. The findings underline the importance of consumer perceptions of the cause and the company and their attitude to the cause. They point to the importance of individual differences that influence consumer perceptions of the cause, the company and brand familiarity. Also of importance is the consumer's attitude to the cause. Conclusions - The findings suggest some practical implications in designing and implementing cause-related marketing campaigns. It is important to enhance brand familiarity and create a favorable attitude to the company and attitude to the cause before designing cause-related marketing campaigns. The rising popularity of cause-related marketing has been attributed to its potential to cut through advertising clutter. The findings in this study suggest that marketing campaigns supporting a cause make a difference.

The robot soccer simulation game is a dynamic multi-agent environment. In this paper we suggest a new reinforcement learning approach to each agent's dynamic positioning in such dynamic environment. Reinforcement learning is the machine learning in which an agent learns from indirect, delayed reward an optimal policy to choose sequences of actions that produce the greatest cumulative reward. Therefore the reinforcement learning is different from supervised learning in the sense that there is no presentation of input-output pairs as training examples. Furthermore, model-free reinforcement learning algorithms like Q-learning do not require defining or learning any models of the surrounding environment. Nevertheless these algorithms can learn the optimal policy if the agent can visit every state-action pair infinitely. However, the biggest problem of monolithic reinforcement learning is that its straightforward applications do not successfully scale up to more complex environments due to the intractable large space of states. In order to address this problem, we suggest Adaptive Mediation-based Modular Q-Learning (AMMQL) as an improvement of the existing Modular Q-Learning (MQL). While simple modular Q-learning combines the results from each learning module in a fixed way, AMMQL combines them in a more flexible way by assigning different weight to each module according to its contribution to rewards. Therefore in addition to resolving the problem of large state space effectively, AMMQL can show higher adaptability to environmental changes than pure MQL. In this paper we use the AMMQL algorithn as a learning method for dynamic positioning of the robot soccer agent, and implement a robot soccer agent system called Cogitoniks.

Modeling hand poses and tracking its movement are one of the challenging problems in computer vision. There are two typical approaches for the reconstruction of hand poses in 3D, depending on the number of cameras from which images are captured. One is to capture images from multiple cameras or a stereo camera. The other is to capture images from a single camera. The former approach is relatively limited, because of the environmental constraints for setting up multiple cameras. In this paper we propose a method of reconstructing 3D hand poses from a 2D input image sequence captured from a single camera by means of Belief Propagation in a graphical model and recognizing a finger clicking motion using a hidden Markov model. We define a graphical model with hidden nodes representing joints of a hand, and observable nodes with the features extracted from a 2D input image sequence. To track hand poses in 3D, we use a Belief Propagation algorithm, which provides a robust and unified framework for inference in a graphical model. From the estimated 3D hand pose we extract the information for each finger's motion, which is then fed into a hidden Markov model. To recognize natural finger actions, we consider the movements of all the fingers to recognize a single finger's action. We applied the proposed method to a virtual keypad system and the result showed a high recognition rate of 94.66% with 300 test data.

Many organisms control their physiology and behavior in response to the local light environment, which is first perceived by photoreceptors that undergo light-dependent conformational changes. Phytochromes are one of the major photoreceptors in plants, controlling wide aspects of plant physiology by recognizing the light in red (R) and far-red (FR) spectra. Higher plants have two types of phytochromes; the photo-labile type I (phyA in Arabidopsis) and photo-stable type II (phyB-E in Arabidopsis). Phytochrome B (phyB), a member of the type II phytochromes in Arabidopsis, shows classical R and FR reversibility between the inter-convertible photoisomers, Pr and Pfr. Interestingly, the Pr and Pfr isomers show partitioning in the cytosol and nucleus, respectively. In the over 50 years since its discovery, it has been thought that the type II phytochromes only function to mediate R light. As described in the text, we have now discovered phyB has an active function in FR light. Even striking is that the R and FR light exert an opposite effect. Thus, FR light is not simply nullifying the R effect but has an opposing effect to R light. What is more interesting is that the phyB-mediated actions of FR and R light occur at different cellular compartment of the plant cell, cytosol and nucleus, respectively, which was proven through utilization of the cytosolic and nuclear-localized mutant versions of phyB. Our observations thus shoot down a major dogma in plant physiology and will be considered highly provocative in phytochrome function. We argue that it would make much more sense that plants utilize the two isoforms rather than only one form, to effectively monitor the changing environmental light information and to incorporate the information into their developmental programs.

This paper aims to develop the numerical model for prediction of the channel migration by analyzing of sediment and flow characteristics with patterns of channel in alluvial rivers. Flow in rivers constitutes to be the meandering or the braided form and rarely straight channel through morphologically stable patterns with mutual actions between the flowing water and bed materials. In order to develop the model for simulation of the channel migration, the channels are divided into two types with positive or negative sign by the direction of curvature radius of the centerline channel ($r_c$). That is, the single bend-channel consists of only one curvature of positive or negative sign and the multi-bend channel consists of two more curvatures of positive or negative sign, respectively. The model analyzes the sediment and flow characteristics under the influence of superelevation, spiral motion, irregularity in bed topography and depth-averaged velocity of channels. For reliability of this model, the single bend-channel and the multi bend channel are compared with experiment data in other models and the measured field data in the Keum-River, respectively. As a result, the both com parisians turn out to be excellent.

The Honolulu Strategy is a framework document to address marine debris issue globally. The Fifth International Marine Debris Conference held in March 2011 and organized by NOAA and UNEP catalyzed the development of the Holonulu Strategy. Goals of the Strategy are to reduce the amount and impact of land-based, sea-based, and accumulated marine debris. A set of strategies for each goal were provided for education and awareness, legislation, and alternative technologies. The Strategy also lists indicators that could be used to evaluate outcomes of strategies. The adoption of the Honolulu Strategy by the international community has led the international organizations such as GPA, IMO, and CBD to strengthen their responses to the marine debris issue. UN has also set up specific actions that will be implemented until 2025 through its resolutions on marine debris. Recent global developments related to the marine debris issue might lead to a change in the character of the international marine debris management from the current soft law regime to a mandatory one. The Honolulu Strategy could provide a guideline when the Korean government formulates the Second Basic Plan for Marine Debris Management, especially with its prevention-oriented approaches, utilization of scientific policy development tools, and adoption of evaluation system using performance indicators.

The purpose of this study is to develop a new architectural language and design strategies that would anticipate and incorporate new historical situations and new paradigms to understand the world. It consists of four sections as follows: First, it presents a new interpretation of space, human body, and movement that we find in modern art and tries to combine that new artistic insight with environmental design to provide a theoretical basis for performance-event architecture. Second, it conceives of architectural environment as a combination of space, movement, and probabilistic situations rather than a mere conglomeration of material. It also perceives the environment as a stage for performance and the act of designing as a performance. Third, in this context, man is conceived of as an organic system that responds to, interacts with, and adapts himself to his environment through self-regulation. By the same token, architecture should be a dynamic system that undergoes a constant transformation in its attempt to accommodate human actions and behaviors as he copes with the contemporary philosophy characterized by the principle of uncertainty, fast-changing society, and the new developments in technology. Fourth, the relativistic and organic view-point that constitutes the background for all this is radically different from the causalistic and mechanistic view that characterized the forms and functions of modernistic design. The present study places a great emphases on dematerialistic conception of environment and puts forth a disprogramming method that would accommodate interchangeability in the passage of time and the intertextuality of form and function. In the event, performance-event architecture is a strategy based on the systems world-view that would enable the recovery of man's autonomy and the reconception of his environment as an object of art.

Although national and regional environmentally friend agriculture (EFA) and food development programmes such as the Life-Food Development Plan (LFDP) have been established in Korea, some policy measures in these programmes seem to be unsuitable for Korean organic farming development. Policy measures tend to support external input purchases of organic fertilizers rather than market development actions such as providing consumer information, research, education, training and statistical data collection. The development of an organic action plan (OAP) for Korea is therefore considered essential for the sustainable future of organic farming in Korea. The purposes of OAP are 1) to define and set the clear goals/targets for the organic sector development, 2) to integrate various organic stakeholders and public institutions in partnership, 3)to focus on specific issues with tailored measures and 4) to integrate and develop different policy measures (Stolze, 2005). Most EU member state countries have developed their own OAPs and each reflects its own priorities with regard to organic sector development. This study compares and contrasts the Welsh, England and EU OAP with the Korean Jeonnam Life-Food Development Plan (LFDP) in order to facilitate the development of the organic food and farming sector in Korea. Early action plan, for example, the first Welsh OAP(1999) focused support on developing the supply of organic products whereas later action plans (e.g. England OAPs in 2002 and 2004 and the second Welsh OAP in 2005) focussed more on developing consumer demands for organic products. The EU OAP (2004) also aims at market support related to consumer demand and then organic farming production for its environmental and other social benefits. OAPs not only provide specific issue-solving tools but also perform a role as providing a focus for organic sector development as a whole. The Korean LFDP provides issue-solving tools but plays no regulatory role such as policy development, harmonizing various policy measures and conflicting factors and providing evaluation tools for further development. A national-level OAP could also facilitate international trade of organic products. To achieve better harmonized and sustainable approaches for the Korean organic industry, National- as well as regional- regulatory policy systems are urgently required in the form of an Organic Action Plan.
