This paper demonstrated how application of evolutionary knowledge to developmental perspectives enhances understanding of human ontogeny. Evolutionary Developmental Psychology (EDP) explains human behavior through evolutionary principles and focuses on ontogeny rather than phylogeny. In this paper, the authors review concepts of evolution, adaptations, and the processes of evolution from EDP perspectives. The definition and basic assumptions of EDP are introduced, followed by explanations of how evolution happens in ontogeny by looking at developmental systems approaches, concepts of ontogenetic and deferred adaptations, evolution of childhood, and brain plasticity. Possible pathways of evolution in ontogeny are also discussed. Finally, some research methodology for applying EDP to child development is suggested with specific hypotheses and studies.

The power plant system of a tilt rotor unmanned aerial vehicle (UAV) was verified by the Ironbird ground test, which considerably reduces cost and risk during the developmental stages. The function and performance of the engine, drive line, nacelle conversion, and rotor systems were evaluated using a building block test approach. The Ironbird test concept facilitates the discovery of potential faults in earlier stages of the testing period. As a result, the developmental testing period could effectively be shortened. The measured test data acquired through a ground control and data acquisition system exhibited satisfactory results which meet the developmental specifications of a tilt rotor UAV.

The concepts of phylogeny and floral genetics play a crucial role in understanding the origin and diversification of flowers in angiosperms. Angiosperms evolved a great diversity of ways to display their flowers for reproductive success with variations in floral color, size, shape, scent, arrangements, and flowering time. The various innovations in floral forms and the aggregation of flowers into different kinds of inflorescences have driven new ecological adaptations, speciation, and angiosperm diversification. Evolutionary developmental biology seeks to uncover the developmental and genetic basis underlying morphological diversification. Advances in the developmental genetics of floral display have provided a foundation for insights into the genetic basis of floral and inflorescence evolution. A number of regulatory genes controlling floral and inflorescence development have been identified in model plants such as Arabidopsis thaliana and Antirrhinum majus using forward genetics, and conserved functions of many of these genes across diverse non-model species have been revealed by reverse genetics. Transcription factors are vital elements in systems that play crucial roles in linked gene expression in the evolution and development of flowers. Therefore, we review the sex-linked genes, mostly transcription factors, associated with the complex and dynamic event of floral development and briefly discuss the sex-linked genes that have been characterized through next-generation sequencing.

This paper presents a developmental approach undertaken by Asiana Airlines to implement computerized reservation system (CRS), Asiana Airlines is a new entrant into the once monopolized airline business in Korea. As a new entrant, it was absolutely necessary to develop CRS fast to begin the business in a relatively short period of time. By taking the risk of choosing Airline Control System which no airlines has yet implemented CRS with, Asiana Airlines was able to shorten development time considerably as well as integrate CRS with internal management information systems. This enhances system flexibility greatly. It is initially viewed that developing CRS is not to get competitive advantage but to overcome competitive disadvantage at Asiana Airlines. The paper also surveys the changing environment of CRS in general and the future implementation plan for ARTIS(Asiana Airline Reservation and Travel Information System) to be more of a competitive weapon in increasingly competitive international air travel market.

Objective : This recent work intended to provide basic information for researchers and practitioners related to occupational therapy about Developmental Coordination Disorder (DCD) in South Korea. The previous research of screening DCD and the effects of intervention programs were reviewed. Methods : Peer-reviewed papers relating to DCD and published in Korea from January 1990 to December 2020 were systematically reviewed. The search terms "developmental coordination disorder," "development coordination," and "developmental coordination" were used to identify previous Korean research in this area from three representation database, the Research Information Sharing Service, Korean Studies Information Service System, and Google Scholar. We found a total of 4,878 articles identified through the three search engines and selected seventeen articles for analysis after removing those that corresponded to the overlapping or exclusion criteria. We adopted "the conceptual model" to analyze the selected articles about DCD assessment and intervention. Results : We found that twelve of the 17 studies showed the qualitative level of Level 2 using non-randomized approach between the two groups. The Movement Assessment Battery for Children and its second edition were the most frequently used tools in assessing children for DCD. Among the intervention studies, the eight articles (47%) were adopted a dynamic systems approach; a normative functional skill framework and cognitive neuroscience were each used in 18% of the pieces; and 11% of the articles were applied neurodevelopmental theory. Only one article was used a combination approach of normative functional skill and general abilities. These papers were mainly focused on the movement characteristics of children with DCD and the intervention effect of exercise or sports programs. Conclusion : Most of the reviewed studies investigated the movement characteristics of DCD or explore the effectiveness of particular intervention programs. In the future, it would be useful to investigate the feasibility of different assessment tools and to establish the effectiveness of various interventions used in rehabilitation for better motor performance in children with DCD.

Functional neurology is a function-oriented clinical neurology with a focus on the viability, functionality, and balance of the neurologic system, which may be considered as a form of yin-yang balance medicine like Korean medicine. While it incorporates knowledge systems such as developmental neurology, neuropsychology, comparative neuroanatomy, and others, it views the neurologic system and the body as an individually different, self-regulating mechanism with the help of the active balancing mechanism within the nervous system and between the individual and the environment, which view is at the core of its effort to improve and serve the human dignity based on the best possible functioning nervous system. This article reviews core concepts of the functional neurology, discusses yin-yang balance medicine perspectives and clinical applications of it.

Development of the mammalian pre-implantation embryos has unique features, such as a slow and unsynchronized cell division, compaction, and eventual formation of blastocysts with inner cell mass and trophectoderm. In order to have a clue on molecular mechanisms that reside in mouse early development, we suppressed expression of early embryo-specific genes with RNAi and observed their development in vitro. We observed developmental defects in embryos microinjected with dsRNAs for Oct4 or Nanog among the tested genes. Careful examinations revealed that development of the most of the Oct4- or Nanog-suppressed embryos were arrested at the morula stage. These results suggest that the Oct4 and Nanog activities are also required for embryogenesis earlier than the blastocyst stage.

One hundred and three random complementary DNA clones representing rainbow trout intestine were par1i811y sequenced as an approach to analyze the transcribed sequences of its genome. Of the sequences generated, 60.0% of the ESTs were represented by 40 known genes. Thirty-five clones of unknown gene products potentially represented 34 novel genes. The most Bbundantly represented messages were the 28S ribosomal protein (6.5%) and beta actin (5.8%). The genes involved in ribosome formation (18%) accounted for the major gene expression. Development of EST panels representing the genes expressed in a particular tissue will be useful in determining the role of these genes in normal function and in response to developmental, hormonal, environmental and physiological changes.

Weapon systems are curcial instruments for the security of a nation and critical elements for the victory in a war. Since modern weapon systems tend to be capital-intensive with high precision and quality, they become more and more complex and diversified; their acquisition costs become huge; and their technological obsolescence becomes accelerated. Therefore, the systematic management of weapon acquisition process would be one of the most important defense tasks at the national level. To analyze such problems and find solutions, this paper has studied various aspects related to the efficient management of weapon system acquisition. After brief summarization of the general characteristics of weapon systems, their effectiveness, and developmental trend, the paper discusses the defense management policies and techniques for the weapon systems. Specifically, four alternative acquisition methods such as indigenous R & D, foreign purchase, co-production and joint-production are discussed and analyzed by systems approach. The systems analysis procedure to evaluate and select weapon acquisition method is as follows; 1) to analyze the merits and demerits of the alternative methods, 2) to screen unrealistic alternatives through the consideration of significant factors such as political, economic, military, technological, and social constraints, 3) to evaluate and select an optimal one among the remaining acquisition methods after the cost-effectivenss analysis. For the base of cost-effectivess analysis, cost analysis model as well as effectiveness analysis model of each acquisition method are developed.

Neurobiological approach helps to resolve the mind-body dualism and develop new assessment and treatment approaches in psychiatry. However, it could be a problem to place too much emphasis on certain aspects of neurobiology, specifically structural neuroanatomy, because of the complexity or comorbidity of neuropsychiatric disorders. Developmental Coordination Disorder (DCD), for instance, is generally related to problems in motor skills and this movement disability is often related to perception. One account, two visual systems theory, relied on functional distinction in brain; ventral stream is responsible for visual recognition, and dorsal stream is responsible for the guidance of actions. However, Studies are now showing that shape perception is relevant to visually guided action, such as reaching-to-grasp an object. In this article, I reviewed fundamental findings of two-visual system theory and suggested problems of visually guided action to consider what shape perception implies for the two visual systems. Questions raised highlight possible limitations of adopting a structural neuroanatomical approach to account for perception and action effects, and by extent related psychiatric conditions such as DCD. In conclusion, neurobiological approach converging to neuropsychiatry, while useful, would be limited if it focuses too much on anatomical distinction.
