  • As a generalization of Berwald spaces, we have the ideas of Douglas spaces and Landsberg spaces. S. Bacso defined a weakly-Berwald space as another generalization of Berwald spaces. In 1972, Matsumoto proposed the (α, β) metric, which is a Finsler metric derived from a Riemannian metric α and a differential 1-form β. In this paper, we investigated an important class of (α, β)-metrics of the form $F={\mu}_1\alpha+{\mu}_2\beta+{\mu}_3\frac{\beta^2}{\alpha}$, which is recognized as a special form of the first approximate Matsumoto metric on an n-dimensional manifold, and we obtain the criteria for such metrics to be weakly-Berwald metrics. A Finsler space with a special (α, β)-metric is a weakly Berwald space if and only if Bmm is a 1-form. We have shown that under certain geometric and algebraic circumstances, it transforms into a weakly Berwald space.

  • This paper discussed the use of the urban greening space beside nature land----special sites of urban Greening. Consider: the special sites of urban greening are referred to the space formed by urban building and framing, where plants can grow under natural or artificial condition. Filly using those spaces will efficiently increase green area, improving ecological environment and landscape in urban area. A classification to special sites of urban greening was put forward, which are the habits of plant combine with the form of buildings. The present status and future trends on urban greening at special sites was discussed and analyzed. Consider: there are two developing trends of the research of urban greening at special sites. Firstly, it is more naturalize and ecologize greening landscape. Secondly, It will take form a techologize in the process of constructing and materials.

  • The objective of this research is significant because it derives the core competency factors that members of education communities must have in order to form warm education communities through investigating the perception of special education teachers. To achieve this, 352 special education teachers and teachers working at special education institutes were asked to record three of the most important factors out of a total of 18 factors that members of an educational community considered to be required in order to form warm educational communities. IBM SPSS Statistics 23 was used to analyze the collected data. First, in oder to examine the demographic characteristics of the educators surveyed, frequency analysis was conducted. Second, frequency analysis on the factors that special education teachers considered to be most important to form a warm education communities was conducted by teacher experience and type of education institute they worked for. When analyzing the research results of main factors that special education teachers considered to be important by teacher experience and type of education institute they worked for, responsibility was confirmed to be the most important factor. The second most important factor was communication and the third most important factor was responsibility and trust. In summary, the research confirmed that if mutual trust between the members of an education community can be established and if problems can be solved through cooperation and through open communication, and if each member of the community serves their role responsibly, a warm education community can be formed.

  • All things considered, cataloging rules of every nations in the world had been revised or attempt to revise according to the ISBD cataloging method. This is a general tendency of cataloging rules in nowadays. But, for the application to ISBD cataloging method to in the cataloging rules for oriental classics, there are many bottleneck because special articles of bibliography in the oriental classics frequently appeared, the special article has been recorded to suitably location in the body of entry. If special articles have apply to ISBD cataloging method, it must given to peculiar mark in the every articles. Representative examples are location for entry to material form of printed letter and form of printed book. Generally, material form of printed letter have been recorded in the article of edition, form of printed book have been recorded in the article of collation. But, as these method have not regulated in the general cataloging rules of Korea, material form of printed letter and form of printed book articles must record in article of note for application to ISBD cataloging method. If that happens, fundamentally problems which have been hotly debated in cataloging rules for oriental classics will be naturally solve. In the edded, I was presented the solution method of accompanying problems in this thesis.

  • All of sealing capsules to transport a special form radioactive material should be designed and fabricated in accordance with the design criteria prescribed in IAEA standards and domestic regulations. The objective of this study is to demonstrate the safety of a shipping capsule for $^{192}Ir$ special form radioisotope which produced in the HANARO. The safety tests were carried out for the impact, percussion, bending and heat test conditions. And leakage tests were carried out before and after the each test. Also, the safety analyses wert performed using computer codes in order to verify the test results. The capsule showed slight scratches and deformation, and maintained its structural and thermal integrities in all tests without any severe damage or melting. It also met the allowable limits of leakage rate after each test. Therefore, it has been verified that the capsule was designed and fabricated to meet all requirements for the special form.

  • This study attempted at first to find out a more suitable form of catalog to guide library users who need subject approach through a literature survey, secondly to see how and which catalog form is kept by Korean research or special libraries through an analysing questionnaires, and thirdly to evaluate these data and explore the ways to improve the function of classified catalog in Korean research or special libraries. The findings of this study shows that a classified catalog is more desirable form of catalog in research or special libraries in Korea because of the diversity of languages of the literatures needed by researchers, the educational programs for librarians and the problems of subject heading lists. Above mentioned questionnaire survey shows that more than $70\%$ of research or special libraries in Korea uses classified catalogs. However, among those libraries - only $8\%$ has the index of cassified catalog which is prerequisite for the catalog users. This survey also indicates that recently many libraries began or converted classified catalogs to subject catalogs. The writer explains the beginnings or convertings of classified catalog to subject catalog is due to the fact that many libraries do not have the index of a classified catalog which is badly needed by the library users. Based on these findings, writer said that to improve the function of the present classified catalog, it should include it's index to guide the library users who are not familier with the classifing system of the subjects. Through the entire paper, the writer has attempted to develop a point of argument by comparing a classified catalog with a subject catalog. Writer's point is not only a subject catalog using the particular language terms as a communication tool has problems in itself, but also the prevailing of this catalog form in North America is caused by their different situations from ours.

  • Students taking linear model courses have difficulty in determining which parametric functions are estimable when the design matrix of a linear model is rank deficient. In this note a special form of estimable functions is presented with a linear combination of some orthogonal estimable functions. Here, the orthogonality means the least squares estimators of the estimable functions are uncorrelated and have the same variance. The number of the orthogonal estimable functions composing the special form is equal to the rank of the design matrix. The orthogonal estimable functions can be easily obtained through the singular value decomposition of the design matrix.

  • The purpose of this study is to investigate the correlation between aluminum form work and noise-induced deafness by conducting special health examination on construction aluminum worker and noise measurement at the workplace. All the 11 aluminum form workers were diagnosed with noise-induced deafness after holding a special health examination. The workers have not had any previous history of noise-induced deafness which indicates that aluminum form work is related to noise-induced deafness disease. The impact noise of 120 dB(A)~125 dB(A), which exceeds the regulations of industrial safety and health act, was found during the dismantling rather than installation when noise measurement was made at the aluminum workplace. The aluminum form workers could permanently lose the hearing sense if they are exposed to this impact noise. This study is to suggest the method to prevent noise-induced deafness for aluminum form workers by firstly giving out hearing protection equipment at the construction site and secondly installing rubber mat, soundproof panel as well as changing the noise-lowering technique.
