Purpose: The purpose of the study was to review functioning components of studies for measuring functional information using International Classification of Functioning, disability and health (ICF) in Korea. Methods: A literature review was conducted and eligible studies were identified via search of RISS, KISS, DBpia, KoreaMed, PubMed, and ISI databases published from 2001 to 2015. For inclusion in this review, a study should be published in a peer-review journal, must have participation of Korean researchers and/or developed in Korea, and should provide functioning data related ICF. Descriptive studies containing only ICF concepts and review studies were also excluded. Collected functioning data in each study were analyzed using frequency based on ICF domain. Data assessment was performed by two independent reviewers. Results: Eighty publications were included in the analysis. The majority of studies collected data from clinical patients (n=38) and from the disabled (n=28). Fourteen studies assessed functioning data from the elderly and students under special education. The studies reported functioning data using various tools, including ICF itself, ICF checklist, coresets, and conventional measurement tools. Body function domain was most commonly used and the least used domain was the body structure across areas. Interestingly, increasing data related to environmental factors was observed in all studied populations. Conclusion: Functioning data was collected from four domains of ICF across professional areas. The most common collected data was body function and activity and participation for which conventional measurement tools are already available. To understand clients, components of environmental factors that might influence a person's functioning should be considered.

Typical temperature control methods of a cooler for machine tools are hot-gas bypass and compressor variable speed control. The hot-gas bypass system has been widely used to control the cooler temperature in many general industrial fields. On the contrary, the compressor variable speed control is focused on special fields such as aerospace and high precision machine tools which need high precision control. The variable speed control system usually has two control variables such as target temperature and superheat. In other words, the variable speed control system is basically multi-input multi-output(MIMO) system. In spite of MIMO system, the proportional integral derivative(PID) feedback control methodology that based on single-input single-output (SISO) system is generally used for designing the variable speed control system. Therefore, it is inevitable to describe transfer functions for dynamic behaviors of every controlled variables and decide the PID gains with tremendous iteration process. Moreover, the designed PID gains do not provide optimum system performances. To solve these problems, high performance controller design method based on a state space model is suggested in this paper. An optimum controller is designed to minimize both control errors and energy inputs. This method was more simple to describe dynamic behaviors and easier to design the cooler controller which is MIMO system.

The article is devoted to the actual problem of studying the possibilities of implementing personalization of the user interface in accordance with the personality psychotypes. The psychological aspect of user interface design tools is studied and the correspondence of their application to the manifestations of personality psychotypes is established. The results of the distribu-tion of attention of users of these categories on the course page of the educational platform are presented and the distribution of attention in accordance with the focus on educational material is analyzed. Individual features and personal preferences regarding the used design tools are described, namely the use of accent colors in interface design, the application of the prin-ciples of typographic hierarchy, and so on. In accordance with this, the prospects for implementing personalization of the user interface of the educational platform are described. The results of the study allow us to state the relevance of developing and applying personalization of the user interface of an educational platform to improve learning outcomes in accordance with the psychological impact of individual design tools, and taking into account certain features of user categories. The research is devoted to the study of user attention concentration using heatmaps, in particular based on eyetreking technology, we will investigate the distribution of user attention on the course page of an educational platform Ta redistribution of atten-tion in accordance with certain categories of personality psychotypes. The results of the study can be used to rearrange the LMS Moodle interface according to the user's psychotype to achieve the best concentration on the training material. The obtained data are the basis for developing effective user interfaces for personalizing educational platforms to improve the quality of the education.

The ultrastructural characteristics of germ cells during spermatogenesis and mature sperm morphology in male Pinctada martensii were investigated by transmission electron microscope observation. The morphologies of the sperm nucleus and the acrosome of this species are the oval shape and cone shape, respectively. Spermatozoa are approximately $47-50{\mu}m$ in length including a sperm nucleus (about $1.24{\mu}m$ in length), an acrosome (about $0.60{\mu}m$ in length), and tail flagellum (about $45-47{\mu}m$). The axoneme of the sperm tail shows a 9+2 structure. In P. martensii in Pteriidae, a special substructure showing a thick and wide triangular shape which is composed of electron-dense opaque material (occupied about 50% of all, the upper part of the acrosomal vesicle), appeared in the upper region (part) of the acrosomal vesicle, while the lower region (part) of the acrosomal vesicle is composed of electron-lucent material. Thus, this special structure, which exist in the upper part of the acrosomal vesicle in P. martensii, is somewhat different from those of other subacrosomal vesicle in other families in subacrosomal vesicles. Therefore, we assume that the existence of a special substructure showing a thick and wide triangular shape in the acrosomal vesicle of the spermatozoon can be used as a key characteristic for identification of P. martensii or other species in Pteriidae in subclass Pteriomorphia. The number of mitochondria in the midpiece of the sperm of this species are five (exceptionally sometimes four), as one of common characteristics appear the same number of mitochondria in the same families of superfamilyies. This species in Pteriidae does not contain the axial rod and satellite fibres which appear in the species in Ostreidae in subclass Pteriomorphia. These characteristics can be used for the taxonomic analysis of the family or superfamily levels as a systematic key or tools.

The purpose of this thesis is to study about destructive method in late twentieth Century Paintings. To do this we will consider the examples of Frank Stella and Anselm Kiefer's expressive methods. And this thesis is designed to investigate the change of the two Modes. The centering change is in the destructive manner of them, and they are traced systematically. In these chapters we will study the procedure of the destruction and specification of the Modes; the subject which contains the special element, the relation between it and the artist's willful meaning, morphological specification, symbol system formative language, subject, material and coloring way. etc. The origin of the methodology is systematically studied and the procedures of the content applicated are considered. In the special characteristics of the methodology, the special feactures it contains will be considered. The basis of the deconstructive idea from Nietsche, Derrida, Saussire, Andrew Benjamin and others will be applied to understand the two Modes of artistic methodology, and whether or not they can be tools of explaining the methodology of our time is distinguished. Next, the methodologically founded contents and concepts from Chapter#2 are related and intertwined together. The outer destructive aspect and inner destructive specification are centrally uncovered by the Interpretation. The resulting background of the Mode, the factor of destruction and central concept, along with the works, applied ideas, and pre-scholar's writings, are conjoined and explained. The characteristics of S Mode are revealed as being similar to those of Vandalic Destruction and Baroque formalistic Style, while K Mode is closely related to Iconoclastic Destruction and Neoclassical Antiformal Style.
