The research sees the catenary dropper clamp using a test equipment which is using actual sample in the field. This test helps the quality improvement of material. For raising the reliability of data, classified it by type and tests especially in the multiple sample but it was under testing in the sample of decimal at circumstance. From the accuracy side of research data it was insufficient because the dropper clamp was in small quantity but it contributes in quality of material improvement. The quality of material data which it gets with spectroscopic was not accurate so hereafter it needs to follow wet analysis and precise analysis to join in the test which is detailed comes to accomplish with the data accuracy.

In this study, Two divisions(language and literature) in schemes of the DDC are discussed. And the adaptation of these divisions to the minor or oriential countries are seggested. In spite of the continuous study and revision of the experts, the frameworks of these systems are still kept unchanged. Only their subdivisions, reflecting those developments In the academic world are developed and detailed more sophisticatedly. Of those subdivisions in DDC, especially the two subdivisions of language and literature are seriously unbalanced. The two divisions give the attention too much to the Western including the English, Deutsch and French. Relatively the languages and literatures of the other nations are treated lightly. It results more problems to the Oriental and the minor nations. So, the libraries of these nations should modify the schedules and develop the subdivisions items of the local emphasis. Considering these problems the historical changes of the DDC system in the languages and literatures are clarified and the problems occurring from unbalanced allocation of the classed items are examined.

Since the development of Graphic Processing Unit (GPU) in 1999, the development speed of GPUs has become much faster than that of CPUs and currently, the computational power of GPUs exceeds CPUs dozens and hundreds times in terms of decimal calculations and costs much less. Owing to recent technological development of hardwares, general-purpose computing and utilization using GPUs are on the rise. Thus, in this paper, we have identified the elements to be considered for the Smart Grid Security. Focusing on a Performance Improvement of the Basic Algorithm for the Stateful Inspection to Detect DDoS Attacks using CUDA. In the program, we compared the search speeds of GPU against CPU while they search for the suffix trees. For the computation, the system constraints and specifications were made identical during the experiment. We were able to understand from the results of the experiment that the problem-solving capability improves when GPU is used. The other finding was that performance of the system had been enhanced when shared memory was used explicitly instead of a global memory as the volume of data became larger.

The effect of gamma irradiation on the prevention of breeding a patulin-producing mold and reducing patulin content was evaluated in an apple model system. Penicillium griseofulvum, a patulin-producing standard mold strain was artificially inoculated into apples and a gamma irradiation was performed. The $D_{10}$-values of the conidia of P. griseofulvum in an aqueous suspension and the apple model system were calculated at 0.28 and 0.48 kGy, respectively. The viable cell counts of the inoculated conidia in the apples showed 2 decimal point reductions at a dose of 1 kGy. Breeding and growth of the survived conidia was prevented during 10 weeks of post-irradiation storage period, especially at $4^{\circ}C$. The concentration of patulin in the non-irradiated apples was gradually increased and reached about 950 ppm at $25^{\circ}C$ and 410 ppm at $4^{\circ}C$, but the production of patulin was not observed during storage after 1 kGy of gamma irradiation.

Information about the formation and filling (in 2014 to 2016) of a terminological dictionary on electronics and radioengineering and collective work (in 2017 to 2018) with a data bank "TERMIN" is presented in this article. In purpose of creating an instrument of navigating the modern scientific-technical space a net of terms with set semantic links is described. This set is based on the analysis of terms' definitions (each term is checked for inclusion in the definitions of all other terms; the definitions were borrowed from reputable reference editions: encyclopedias, dictionaries, reference books). The created model of a system that consists of different information sources, in which it (information) is indexed by the terminology of Russian State Rubricator of Scientific and Technical Information rubrics and/or keywords, is described. There is an access for the search in all these sources in the system. Searching inquiries are referred to in the language of these rubrics or formulated by arbitrary terms. The system is to refer to information sources and give out relevant information. In accordance with this model, semantic links of various types, which allow expanding a search at different modalities of query, should be set among data bank terms. Obtained links will have to increase semantic matching, i.e., they can provide actual understanding of the meaning of the information that is being sought.

This study reviews various kinds of records filing systems, which function as a basic fundamental to effective records management. The purposes, methods and characteristics of Alphabetic, geographic, numeric, subject, and combined filing systems are examined. The alphabetic filing method uses letters of the alphabet to determine the order of names of people and companies. In subject filing the subjects are filed in alphabetic order. In numeric filing, numbers representing names or subjects are used. When records are requested by place or location rather than by individual or business name, geographic filing is advantageous.

Objective: We propose to apply color information to facilitate finding books in the library. Background: Currently, books are classified in the basis of a decimal classification system and a call number in the library. Users find a book using the call number. However, this classification system causes various difficulties. Method: In a process analysis and survey study, we identify what the real problem is and where the problem is occurred. To solve the real problems, we derived a new search method using color information. We conducted a comparative experiment with 48 participants to see whether the new method can show higher performance. Results: The new method using color information showed faster time and higher subjective rating scores than current call number method. Also, the new method showed faster time regardless of the skill level while the call number method showed time differences in terms of the skill level. Conclusion: The effectiveness of the proposed method was verified by experiments. Users will be able to find the desired book without difficulty. This method can improve the quality of service and satisfaction of library use. Application: Our book search method can be applied as a book search tool in a real public library. We hope that the method can provide higher satisfaction to users.
