This paper deals with the observer design problem for a class of state-delayed nonlinear systems with or without time-varying norm-bounded parameter uncertainty. The nonlinearities under consideration are assumed to satisfy the global Lipschitz conditions and appear in both the state and measured output equations. The problem we address is the design of a nonlinear observer such that the resulting error system is globally asymptotically stable. For the case when there is no parameter uncertainty, a sufficient condition for the solvability of this problem is derived in terms of linear matrix inequalities and the explicit formula of a desired observer is given. Based on this, the robust observer design problem for the case when parameter uncertainties appear is considered and the solvability condition is also given. Both of the solvability conditions obtained in this paper are delay-dependent. A numerical example is provided to demonstrate the applicability of the proposed approach.

This study aimed to investigate the high school students' conceptions about the plate tectonics through visual representation. For this purpose, the subjects were 67 students in 11th-grade high schools in Chungbuk. In order to in-depth understand the students' conceptions about plate tectonics, so the investigator conducted a semi-structured interview. The conclusions were as in the following. After learning the plate tectonics, the students had the alternative conceptions associated with terminology, colors' meanings, plate-related melting, plate's movement, plates' boundaries, mantle's physical conditions, driving forces for plate movement, and they had the organic relations about colors' meanings, mantle's physical conditions, and driving forces of plate movement. Also, the visual representation used to teach plate tectonics influenced on the students' responses about terminology, plates' boundaries, plate-related melting and the mantle's physical features, also this study found the factors of visual representation causing the learners to create alternative conceptions. These results implicated the importance of teacher's role in identifying the students' interpretation process on visual representation, and it needed to improve the factors creating students' alternative conceptions about visual representation and to study the factors further.

In this study, the effect of treating 1-dimensional diffusers on the classroom acoustics was investigated to determine if the diffuser are beneficial for performing the preferred acoustical conditions for speech. A 1/10 scale model of a classroom was used to measure the acoustical parameters, T30, $C_{50}$, STI and SNR in that room. The room acoustical conditions were varied by treating diffusers either on the front or side walls of the classroom. When the diffusers were treated on the side walls around the student's areas, a shorter reverberation time at low frequencies was obtained and resulted in performing uniform reverberation times across the frequency bands. The $C_{50}$ values at mid- and high-frequencies were increased by treating the diffusers either on front or side wall surfaces. The highest STI and SNR values were obtained when the diffuser was treated on the front wall around the teacher's areas. It is found that diffusers are beneficial to increase the intelligibility of speech for the rear seats of the rooms.

Analyzing the psychological and pedagogical literature, we showed the interest of researchers in the problem posed. The concept of competence is considered, which is interpreted as giving the key to solving a wide range of educational and life tasks. Research competence implies the ability to cooperate, enter into contacts, readiness for changes, for self-determination and is an integral quality of the individual, expressed in the readiness and ability to independently search for solutions to new problems and creative transformation of reality based on a set of personal and meaningful knowledge, skills, methods of activity and value attitudes.The article offers conditions that certify the improvement of forms and methods of training students in the formation of research competence of future specialists. The use of innovative technologies contributes to improving the level of training of future specialists: students are better prepared for classes, take an active part in the assimilation of program material in laboratory classes. It is noted that this creates a subject-subject relationship between the student and the teacher, and changes the attitude of students to classes. In the process of such organization of educational activities, students are convinced of the need for knowledge and its effectiveness, learn to compare, generalize, classify, establish cause-and-effect relationships, express opinions, defend their point of view, they ensure success in their studies, and develop research competence. It is proved that in order to apply the latest technologies, the teacher himself must know them well, that is, constantly improve himself, master new methods, techniques, ideas, which will help him create new pedagogical technologies and implement them in the educational process.

The purpose of this study is to emboss the importance of safety education by recognizing the instructor's thoughts on safety and the prevention of safety accidents of early-childhood through the examination, analysis of the education site of safety at early-childhood education facilities. The subject of this were 120 early-childhood teachers in the Jeonbuk areas. The data were collected using questionaries and analyzed by the statistical methods of frequencies. ANOVA with SPSS pc program. The research questions were as follows; 1. What is the understanding of early-childhood teachers on safety recognition? 2. Is there a difference in the understanding of the teacher on safety and the management of the education curriculum on safety education that is being taught at early-childhood education facilities? The main results and solutions of this study were as follows: 1. In order for early-childhood teachers to teach safety education in early-childhood education facilities, they must join a safety mutual aid association or join an insurance policy to furnish an appropriate compensation system. Also, safety education must be systematically taught at a $social{\cdot}national$ level so that teachers and young children can have an understanding on safety under the support and concern of early-childhood education facilities and administration authorities. 2. Results on the comparison of the understanding of safety education and management of actual education of teachers on the actual conditions of the education curriculum of safety education show that although teachers are aware of most items of safety education but the actual education was not being taught. This means that although the teachers are aware of the importance of safety education, the actual education is not being taught.
