How do you carry out data analysis\ulcorner There are few texts and little theory. One approach could be to use a pattern language, an idea which has been successful in field as diverse as town planning and software engineering. Patterns for data analysis are defined and discussed, illustrated with examples.

According to the current eligibility criteria in Korea, only cities with populations of more than one million are eligible to carry out urban rail transit construction projects. This paper suggests measures for improving such systems by reviewing current eligibility criteria for the construction of urban rail transit including subway and LRT in Korea.

All rings are assumed to be associative but do not necessarily have an identity. In this paper, we carry out a study of ring theoretic properties of formal triangular matrix rings. Some results are obtained on these rings concerning properties such as being $I_0$-ring, I-ring, exchange ring.

In this study we carry out usability evaluation for adjustable electric beds for home care that are used the most by the elderly, and examines dissatisfaction of users. In this sense, we performed an interview with stakeholders including bed users, developers and suppliers to develop usability evaluation contents. In addition, we carried out feasibility and reliability study over evaluation form through usability assessment, and developed usability evaluation indicator.

Taq DNA polymerase from Thermus aquaticus is very useful in the polymerase chain reaction. Taq DNA polymerase is classified in the pol I family, represented by E. coli DNA polymerase I. The three-dimensional structural alignment of 3'-5'exonuclease domains from the pol I family DNA polymerases explains why Taq DNA polymerase does not carry out proofreading in polymerase chain reactions. Three sequence motifs, Exo I, II, and III, must exist to carry out 3'-5'exonuclease activity for proof- reading by a 3'-5'exonuclease reaction, but these are abolished in Taq DNA polymerase. The key catalytic module in 3'-5'exonuclease is two metal ions chelated by four active-site carboxylic amino acids. Taq DNA polymerase was mutagenized to construct the catalytic module in the active site. The circular dichroism technique supported the formation of the catalytic module, and the radioactive assay showed that the 3'-5'exonuclease activity doubled in the mutant Taq DNA polymerase.

Purpose: This study aims to provide foundational data for preparing for educational programs on the role of a father that are designed to help primiparous spouses carry out the paternal role successfully. Methods: This study was conducted in two OB/GYN clinics and a study sample of 277 primiparous spouses who satisfied the selection criteria was selected. Results: Of the correlation among the childhood experiences, paternal attachment and role of a father of the subjects, the childhood experiences had a positive correlation with the paternal-infant attachment and the role of a father. The paternal-infant attachment and the role of a father also had a positive correlation. Conclusion: An infant is influenced primarily by his or her parents, who will have immense influences on the child's growth and development. Since the paternal-infant attachment is closely related to the role of a father, the development of positive paternal-infant attachment must be preceded in order for a primiparous spouse to carry out the role of a father successfully. Therefore, the development of nursing intervention programs is needed to foster the proper understanding of the role of a father, accommodate the practical needs of primiparous spouses and nurture the paternal-infant attachment for the promotion of realistic, successful role of a father.

Speech recognition system is developed of standalone, In case of a mobile terminal using that low recognition rate represent because of limitation of memory size and audio compression. This study suggest vocabulary recognition highest performance improvement system for separate acoustic search and lexical search. Acoustic search is carry out in mobile terminal, lexical search is carry out in server processing system. feature vector of speech signal extract using GMM a phoneme execution, recognition a phoneme list transmission server using Lexical Tree Search algorithm lexical search recognition execution. System performance as a result of represent vocabulary dependence recognition rate of 98.01%, vocabulary independence recognition rate of 97.71%, represent recognition speed of 1.58 second.
