To address the requirements of gap analysis for species protection, as well as the needs of state and federal agencies for detailed digital land cover, a 43-class map at the vegetation alliance level was created for the state of Kansas using multi-temporal Thematic Mapper imagery. The mapping approach included the use of three-date multi-seasonal imagery, a two-stage classification approach that first masked out cropland areas using unsupervised classification and then mapped natural vegetation with supervised classification, visualization techniques utilizing a map of small multiples and field experts, and extensive use of ancillary data in post-hoc processing. Accuracy assessment was conducted at three levels of generalization (Anderson Level I, vegetation formation, and vegetation alliance) and three cross-tabulation approaches. Overall accuracy ranged from 51.7% to 89.4%, depending on level of generalization, while accuracy figures for individual alliance classes varied by area covered and level of sampling.

The aim of this article is to describe direction of Sino-Russian relations toward a new epoch - as the decision-making centers of both countries define them - indicating the commitment to building the future international order. It includes the synthesis of evolution of relations, descriptions of cooperation building of mutual confidence by both sides in variety of institutions; analyses of geo-economic relations emphasizing their geostrategic dimension and finally dynamics showing how two great powers want to achieve new areas of cooperation focused on building multipolar world order which is the essence of "new epoch". The argument goes towards recognizing the relationship as a "hhybrid alliance". This hybridity is a structural factor that can constrain the use of new dimensions of asymmetric interdependence as political leverage especially by United States against the two non-western powers but also facilitate to use it against West.

The objectives of this study are to define the fundamental notions of collaboration in design field. The results of this study are summarized as follows: Firstly, collaboration means a cooperative work which are cooperatively done by collabarator and collaboratee on the equal status within a certain period of time, based on core ability of each of them. This cooperative work is presented with a visual image based on the identity of participants, and it creates an added value. Collaboration is different from convergence and hybrid in the methodological aspects and from brand alliance and strategic alliance in the aspects of the subject of project. Secondly, collaboration has been developing through step of using the specific ability, step of sharing each core abilities, and step of fusing their identities, in a view of the sphere of cooperative work and the intimate relations in reciprocity. Thirdly, according to strategic purpose, collaboration can be classified into value ascending collaboration, image changing collaboration, business-field extension collaboration, and event collaboration. Fourthly, production methods of collaboration consist of limited edition method, premium line method, common line method, producing a collaborative product, and so on. Fifthly, differentiation effect, image upgrade effect, production of higher value-added products, sale increase, diversification of business, sharing the targets, and promotion effect are achievable through collaboration. Sixthly, to make progress in collaboration successfully, the compatibility of combination between collaborator and collaboratee, the superiority of collaboratee, definitude of collaboration, the fit method of collaboration, the novelty of collatoration, possibility of issuing of collaboration, and perfection of collabo-product must be the points which deserve our attention.

Purpose: The purpose of this study was to define and clarify the concept of developmental care for preterm infants. Methods: The hybrid model method was used to identify the main attributes and indicators. In the field work stage, data were collected in Seoul and Cheonan, Korea. The participants were 5 nurses working in the NICU. Results: The concept of developmental care was found to have six attributes and ten indicators in 2 dimensions. For the nursing practice dimension, four attributes were derived. They were being like intrauterine state, individualization, interaction, and integrative care with awareness of development. For the family centeredness dimension, supporting parental attachment and professional alliance were attributes of developmental care. Conclusion: Developmental focused care can facilitate the identification of behavioral responses of newborns and provide individualized interventions for fostering growth and development. This concept analysis could provide guidelines for "developmental care" nursing practice and be useful for research in the neonatal field.

Bring this analysis down to people-centered development perspective and looking through democratization in the Philippines, Thailand and Indonesia, we find similarities and differences among them related with the intensity of conflicts between development and human rights in the process of democratization in line with global transformation. Civil society in the Philippines criticized the developmental path in the Philippines which failed to implement land reform and eradication of poverty under the transition from 'patrimonial oligarchy' to democracy. In Thailand the coalition of military and the royalists had consolidated its power since Sarit military regime, which later paved the way 'hybrid oligarchy' era. Most Thai civil society organizations has regarded their developmental experience rather as 'maldevelopment' which disregarded economic and social rights. It has been especially believed by Thai localists that the stimulation of local markets and the building of autonomic community society will form the alternative economy without going against the conservative banner of nation, religion and king. Thaksin as a populist successfully took advantage of Thai localist ethos in favour of taking the seat of power. He projected himself as a modernizer focused on economic growth and cleaner politics. However Thaksin's procedural legitimacy was overthrown by counterattacking from military-royalist alliance, pretexting that Thaksin caused internal conflicts and lacked morality. Soeharto's New Order regime which can be called 'administrative oligarchy' had an antipathy towards notions of economic and social rights as well as civil and political rights. In spite of the fact that the fall of Soeharto opened the political space for democratic civil society organizations which had long struggled with development aggression and human rights abuses, there have been continuously a strong political and military reaction against human rights activists, NGOs and ethnic minorities such as Aceh and Papua. Nevertheless, Indonesian democracy is more promising than Philippine's and Thai democracy in terms of comparatively less pre-modern legacies.

On the day of 24 February 2022, Ukraine was invaded by Russia which signed to ensure definitely the Ukraine's national sovereignty, territorial integrity and security under the UN General Assembly Security Council A/49/765, named as the Budapest Agreement. This invasion is the 2nd invasion succeeded in Crimean Peninsula invasion of March 2014 after the Ukraine's national independence in 1991 from the USSR. However this invasion has been continuing for much more than one year. Although Ukraine President appealed the 'peace' toward Russia and claimed also to justify the Budapest Agreement of 1994 toward U.S.A., even any justifications were not appealed. The critical moment of the national abolition could be escaped from the unified desperate spirit of all nations including the president, political-social leaders and military members. Such patriotic and self-help spirits in Ukraine resulted in the active supports from the U.S.A., western and eastern free democratic countries, NATO and EU, and even the neutral countries. Furthermore these supports are increasing much more day-after-day. The lessons which the Ukraine War offers to the Korean national security should be cored with the development of self-reliant national defense capabilities, self-strenuous efforts and unity strengthening of the Korean-U.S. Alliance with the deep confidence.

HomePlug AV(HPAV) is the standard for distribution of Audio/video content as well as data within the home by using the power line. It uses a hybrid access mechanism that combines TDMA with CSMA/CA for MAC technology. The CSMA/CA protocol in HPAV has two main control blobs that can be used for access control: contention window(CW) size and deferral counter(DC). In this paper, we extensively investigate the impacts of CW and DC on performance through simulations, and propose an adaptive mechanism that adjusts the CW size to enhance the throughput in HPAV MAC. We find that the CW size is more influential on performance than the DC. Therefore, to make controlling the network easier, our proposal uses a default value of DC and adjusts the CW size. Our scheme simply increases or decreases the CW size if the network is too busy or too idle, respectively, We compare the performance of our proposal with those of the standard and other competitive schemes in terms of throughput and fairness. Our simulation and analysis results show that our adaptive CW mechanism performs very well under various scenarios.

The development of lightweight, low energy and small-sized sensors incorporated with the wireless networks has brought about a phenomenal growth of Wireless Sensor Networks (WSNs) in its different fields of applications. Moreover, the routing of data is crucial in a wide number of critical applications that includes ecosystem monitoring, military and disaster management. However, the time-delay, energy imbalance and minimized network lifetime are considered as the key problems faced during the process of data transmission. Furthermore, only when the functionality of cluster head selection is available in WSNs, it is possible to improve energy and network lifetime. Besides that, the task of cluster head selection is regarded as an NP-hard optimization problem that can be effectively modelled using hybrid metaheuristic approaches. Due to this reason, an Improved Coyote Optimization Algorithm-based Clustering Technique (ICOACT) is proposed for extending the lifetime for making efficient choices for cluster heads while maintaining a consistent balance between exploitation and exploration. The issue of premature convergence and its tendency of being trapped into the local optima in the Improved Coyote Optimization Algorithm (ICOA) through the selection of center solution is used for replacing the best solution in the search space during the clustering functionality. The simulation results of the proposed ICOACT confirmed its efficiency by increasing the number of alive nodes, the total number of clusters formed with the least amount of end-to-end delay and mean packet loss rate.
