In modern society, the organization of the educational process plays an important role in education. Traditionally, it is through communication and dialogue between the teacher and the student that professional competence is acquired. As society develops, the demand in the global labor market changes and the requirements and criteria for specialists increase. Therefore, a new approach to managing the pedagogical interaction between a teacher and a student in the process of education in a higher educational institution allows a positive impact on the system of training specialists and opens up new prospects for the formation of competitive specialists. The issue of the quality of education is a key one and is covered in the documents regulating the process of educational activities. Also an important problem today is the transition to qualitatively new and innovative systems of training specialists and the departure from outdated models of managing pedagogical interaction in higher education institutions. The process of managing the pedagogical interaction between a teacher and a student is one of the most important for studying in the context of higher education. Thus, the main task of the study is to analyze the role of communication and dialogue during studies in higher education. As a result of the study, current trends and prerequisites for communication and dialogue tools during studies in higher education

This study aims to examine individual perceptions and lived experiences of the Net generation of student teachers and the previous generation of teachers about their technology use in education. The participants of this study include 106 pre-service teachers and 50 in-service teachers from one teacher education university in Korea. Employing a mixed methodology, we first empirically examined the participants' perceptions toward multiple variables related to technology use in education, namely (a) past ICT experiences in schools, (b) personal computer use, (c) constructivist belief, (d) computer efficacy, (e) attitude toward computer in education, and (f) prospective computer use. In addition, we conducted face-to-face interviews with selected participants for the in-depth investigation of their lived experiences about technology use, beliefs, and attitude. Results indicate that there are significant differences between in-service and pre-service teachers in their prior experiences with technology in schools. However, the pre-service and in-service teachers did not differ significantly in their beliefs, attitude and other technology-related variables, which may indicate the danger of generational determinism in the Net Generation debate. The analysis of interview narratives revealed two major themes about the interplay of one's agency and structural changes in the participants' lived experiences with technology use in education: (a) transition from negative past experiences to opportunities for positive computer use, and (b) attitudes formation and change through apprenticeship experiences and structural influences. In conclusion, this study suggests that the Net Generation debate should move beyond dichotomous or techno-centric thinking. There is a critical need to pay more attention to develop deeper understandings of the fundamental diversity existing within the generation itself. Implications for teacher education are also discussed.

본 연구에서는 국가인적자원개발 체제로서 산업인력양성을 위한 직업교육이 국가 경제 및 산업, 사회문화적 맥락과 어떤 관련성을 갖고 변천 과정을 거쳤는지를 파악하였다. 첫째, 우리나라의 경제 환경, 산업발달, 사회 변화에 따라 산업인력양성 체제로서의 직업교육이 어떻게 변해왔는지, 둘째, 직업교육의 역할과 비중에 영향을 준 주요 요인들은 무엇인지, 셋째, 산업인력양성 체제로서의 직업교육과 이공계 인력양성은 국가인적자원개발 모형 관점에서 어떻게 다르게 변화했는지를 분석하였다. 이를 위해 국내·외 학술지 논문, 연구보고서, 학위논문 등의 문헌을 조사하여 시대별로 구분하고 시대 별 경제, 산업, 사회적 이슈, 정책과 연관하여 직업교육의 주요 변화를 분석하였다. 연구결과 첫째, 산업이 고도화되면서 직업교육의 수준은 높아지고 범위는 확장되는 양상을 보였다. 둘째, 직업교육은 제조업 산업 기반 이후 점점 축소되는 경향을 보였고 특히 중등직업교육은 경공업 중심의 국가 산업 이후 쇠퇴하는 경향을 보였다. 셋째, 1970년대 이후 산업의 고도화에 따른 국가인적자원개발의 다양화 및 직업의 다양화로 학력 수준에 따른 임금 격차가 생겼고 이는 대학교육에 대한 선호를 높여 중등직업교육을 기피하는 현상이 발생하게 되었다. 또한, 이공계 인력양성에 초점을 맞춘 국가인적자원개발 모형을 제안하여 직업교육 전반에 초점을 맞춘 기존 국가인적자원개발 모형을 비교하였고, 국가인적자원개발을 다양한 분야나 수준별로 세분화하여 모형을 도출하고 변화를 살펴볼 필요가 있음을 밝혔다. 연구 결과로부터 우리나라 직업교육, 특히 중등단계 직업교육은 경제 성장과 교육열, 외환위기와 같은 외부 충격에 의해 사회문화적 인식에 큰 영향을 받아 쇠퇴해 왔으며, 직업교육의 위기를 극복하기 위해서는 이러한 인식을 바꾸려는 장기적 노력이 필요함을 시사점으로 제시하였다.

This study examined 10 Korean children's expressions of the mental states of desires and beliefs by analyzing mental state verbs as well as modal expressions in Korean production data. Mental expressions of desires and beliefs increased with increasing age. Two transition points of desires and beliefs were found in the data. First, belief expressions were less frequently produced than expressions of desires between 23 to 32 months. Second, belief expressions were much the same as desire expressions from 33 to 44 months. Finally, belief expressions were more frequently produced than desire expressions between 45 to 76 months. The authors suggest that these developmental transitions represent a conceptual change in understanding of mental states as proposed by Wellman (1990).

The objectives of this study are to research into the traditional costume succession in south and north korea, and to compare similarity and difference of kinds, names, drawing of Jegory. Conclusions are described as follows: 1. In sort of Jegory, south and north korea have same kind of Jegory according to traditional form. But in making method, south korea have pursued various style from traditional type to modern type, north korea have maintained just simple and practical basic style. 2. South and north korea have used same or similar names for the basic part of Jegory. But north korea has made new names for constructional needs, so many differences were shown in the name of details. 3. In drawing of Jegory, north korea has hold traditional method and then tried to seek for rational, scientific technique. Also, due to the influence of south korea that advanced in modern aesthetic, drawing of Jegory in north korea were changed to similar.

The local structure of defects in undoped, Si-doped, and neutron irradiated free standing GaN bulk crystals, grown by hydride vapor phase epitaxy, has been investigated by employing electron magnetic resonance(EMR), Raman scattering and cathodoluminescence. The GaN samples were irradiated to a dose of $2{\times}10^{17}$ neutrons in an atomic reactor at Korea Atomic Energy Research Institute. There was no appreciable change in the Raman spectra for undoped GaN samples before and after neutron irradiation. However, a forbidden transition, $A_1$(TO) mode, appeared for a neutron irradiated Si-doped GaN crystal. Cathodoluminescence spectrum for the neutron irradiated Si-doped GaN crystal became much broader or was much more broadened than that for the unirradiated one. The observed EMR center with the g value of 1.952 in a neutron irradiated Si-doped GaN may be assigned to a Si-related complex donor.

Novel diphenylphenanthrenes (DPPs) were prepared by a photocyclization method, and the substituent effects of the phenyl groups on the photophysical properties of the phenanthrene chromophore were investigated based on measurements of fluorescence yields, lifetimes, and transient absorption. Fluorescence activities in DPPs are increased by introducing phenyl rings that can enhance the transition moment along the short axis of the phenanthrene skeleton. Intersystem crossing from the fluorescent states to the triplet manifolds is shown to be operative through the triplet-triplet absorption spectra obtained by laser photolysis techniques.

The 87Rb quadrupole coupling constants (e2qQ/h) and the asymmetry parameters (η) in RbMnCl3 were determined from a nonlinear least-squares fit to the 87Rb NMR powder spectra. The spectra were acquired in the temperature range from 260K to 330K. An important feature in this work is the determination of the quadrupole coupling constants and the asymmetry parameters for two physically nonequivalent Rb sites, Rb(I) and Rb(II), as a function of temperature. In addition, a structural phase transition at room temperature was conformed with the changes in the quadrupole coupling constant and the asymmetry parameter of Rb(II) site.

The concept of "set" in school mathematics has undergone many changes according to the revision of curriculum and the transition of the paradigm in mathematics education. In the discipline-centered curriculum, a set was a representative concept which reflected the spirit of New Math. After the Back to Basics period, the significance of a set concept in school mathematics has been diminished. First, this paper elaborated several controversial aspects of the terms related to set, such as a collection and a set, a subset, and an empty set. In addition, the changes of the significance imposed to a set concept in school mathematics were investigated. Finally, this paper provided two alternative approaches to introduce and explain a set concept which emphasized both mathematical rigor and learner's psychology.
