This study attempts to understand the trend of research in the field of education contributed theses of the "Korea Academia-Industrial Society" in the 10 year period from 2006 to March, 2016, and provide the basic data needed for further research projects. It provides the direction for balanced academic research. The 143 theses contributed over this 10 year period were analyzed to determine the number of thesis per year, major of the researchers, number of co-authors, object of research, subject of research, and research method. It was found that the greatest number of theses were published in 2015. There were 77 researchers who majored in early childhood education and more than 64 researchers who majored in Education, while few researchers majored in other fields of study. The number of papers published by two co-authors was 51, that by one author was 44, and that by more than four researchers was 10. The numbers of papers whose object of research was infant and teacher education were 28 and 24, respectively. The number of papers whose subject of research was philosophy, history, psychology, or social science was 35, and that involving education was 27. There were 47 papers whose method of research was quantitative research. The most prevalent method of data analysis was difference verification. Through this analysis of the research trends, we expect to contribute to the balanced development of the academic world in Korea.

The purpose of this study is to develop a hospice intervention program and present basic study data using a method of Meta analysis. Fifteen theses from 2002 to 2017 were collected from the on-line database at Korean Education and Research Information Service and other journals related hospice. Main keywords were 'hospice' and intervention'. The selected 15 theses were analyzed with publication bias, outcome of effect size, non-overlap percentage(U3), 95% confidence intervals and homogeneity. The result of the study is summarized as follows; Publication bias was stable and the effect size of hospice program was significant at. 99. The effective and significant regulation effects were publication years with 2003 to 2007(ES=1.24), publication types with journals(ES=1.33), majors with nursing sciences(ES=1.02), ages with 29 to 30(ES=1.09), later session(ES=1.06) and aroma(ES=1.12). Accordingly, this thesis has its meaning in that it used a Meta-analysis to analyze domestic theses of hospice intervention programs for the first time in Korea. This thesis will prodide specific guidance to researchers trying to develop and utilize hospice intervention programs resulting in helpful usages in professional hospice institutions with implementations of programs.

This study aims to provide basic data for revitalizing creativity research related to early childhood teachers by analyzing creativity research related to early childhood teachers. For this study, 103 master's and doctoral dissertations in Korea, which were searched through the National Assembly Library and the Research Information Sharing Service (RISS), were selected under the themes of 'early childhood teacher', 'creativity', and 'creativity research trends'. The frequency and percentage were calculated by analyzing creativity research related to early childhood teachers with five criteria: research period, research content, research method, research subject, and creativity factor. As a result of the study, first, as for the trends of creativity research related to early childhood teachers, 91 master's theses (88.3%) and 12 doctoral theses (11.7%) were conducted from 1991 to 2022, focusing on master's theses. Second, trends by research content were found in 20 basic studies (19.4%) and 83 practical studies (80.6%). Creativity research related to early childhood teachers is being actively conducted centering on practical research. Third, trends by research method showed 96 quantitative studies (93.2%), 7 qualitative studies (6.8%), and 0 literature studies (0%). Creativity studies related to early childhood teachers were being conducted with a focus on quantitative research. Fourth, the trend by research subject consisted of 100 studies (97.1%) related to early childhood teachers and 3 studies (2.9%) related to pre-service early childhood teachers. Fifth, trends by creativity factor were found in 56 studies (54.4%) related to teacher's variables and 47 studies (45.6%) related to creativity education methods. Studies related to teacher's variables were relatively higher than creativity education methods. As a result of this study, there is a lack of Christian education research in creativity research related to early childhood teachers, so it is expected that it will be done in the future.

For determining the process of bacterial aggregation, glucose was added into water from Lake Baikal which had been stored for seven months. In the presence of a higher concentration of glucose, the abun­dance of single bacteria and aggregates were higher, but the biovolumes of both bacteria were similar. Theses results mean that both free-living and aggregated bacteria have similar maximum sizes and that aggregates are forming with available organic materials. With available organic materials, the biovol­ume of aggregates becomes larger.

In this paper, we show how certain topologies associate with ideals of subtraction algebras on subtraction algebras. We show subtraction algebras to be topological subtraction algebras with respect to theses topologies. Furthermore, we show how certain standard properties may arise. In addition we demonstrate that it is natural for these topologies to have many clop en sets and thus to be highly disconnected via the ideal theory of subtraction algebras.

One-dimensional diffusion processes are characterized by Feller's data of canonical scales and speed measures and, if we apply the theory of spectral functions of strings developed by M. G. Krein, Feller's data are determined by paris of spectral characteristic functions so that theses pairs may be considered as invariants of diffusions under the homeomorphic change of state spaces. We show by examples how these invariants are useful in the study of one-dimensional diffusion processes.

Theses days, the thickness of Brown tube becomes thinner since the display products are rapidly replaced by PDP, LCD etc. Accordingly, the shadow mask part also become flat. We propose the method of designing the surface with crown since the flat surface is fragile to vibration and shock.

In the present paper, some general convergence principles are established in metric spaces and then theses principles are applied to the convergence of the iterative sequences for approximating fixed points of certain classes of mappings. By virtue of our principles, most of the latest results obtained by several authors can be deduced easily.

Queueing models are good models for fragments of communication systems and networks, so their investigation is interesting for theory and applications. Theses queues may play an important role for the validation of different decomposition algorithms designed for investigating more general queueing networks. So, in this paper we illustrate that the batch size distribution affects the loss probability, which is the main performance measure of a finite buffer queues.

Two kinds of crankshaft oil supply system which were called continuous and discontinuous oil sup-ply system have recently been adopted in engine developing process. In order to clarify the lubrication characteristics for theses systems, in this paper, the comparison studies on supplied oil temperature, pressure, aspect ratio of bearings, and radial clearance were carried out for the main and the connecting rod bearing using computational fluid dynamic analysis.
