In this paper, we present recursive algorithms for state space model identification using subspace extraction via Schur complement. It is shown that an estimate of the extended observability matrix can be obtained by subspace extraction via Schur complement. A relationship between the least squares residual and the Schur complement matrix obtained from input-output data is shown, and the recursive algorithms for the subspace-based state-space model identification (4SID) methods are developed. We also proposed the above algorithm for an instrumental variable (IV) based 4SID method. Finally, a numerical example of the application of the algorithms is illustrated.

The furcocercus cercariae of Neodiplostomum seoulense (Digenea: Neodiplostomidae) penetrate the skins of tadpoles and shed their tails. The speculated mechanism of this tail loss was physical efforts required to produce a vigorous zigzag motion during skin penetration; no other mechanism has been proposed. We examined the relationship between the host serum and cercarial tail loss. Cercariae of N. seoulense were collected from experimentally infected Segmentina hemisphaerula, and lots of 300 cercariae were cultured in medium 199 contained several types of sera. Cercarial tail degradation was induced in all media, but all the cercariae cultured except those cultured in media containing fetal bovine serum (FBS) died within 48 hr. After 72 hr cultivation in media containing FBS, cercarial tail degradation was induced in 67.0%; in continuous cultivation 13.3% of larvae survived for 7 days. Tail degradation did not occur in the absence of serum and when serum was heat inactivated at $56^{\circ}C$ for 30 min. The addition of 20 mM ethylenediaminetetraacetic acid (EDTA) blocked cercarial tail degradation completely. Moreover, the addition of 20 mM $MgCl_2$ restored tail degradation blocked by EDTA. These results suggest that the alternative complement pathway is related with the N. seoulense cercarial tail degradation induced by serum.

Normative theory suggests that control systems should be designed to complement management's objectives and strategies. However, few empirical studies have focused on how control systems have been modified to complement new manufacturing techniques, such as zero-defect strategy. The major purpose of this study is to examine the effects of the attributes of quality strategy and control system on performance. The previous studies have subdivided quality strategy into the ECL(economic conformance level) and ZD(zero-defect) strategy. To accomplish the purpose, this study empirically analysed the data based on the questionnaires from manufacturing department personnel of 67 Korean companies. The major results are as follows. The companies that had implemented the ZD strategy and its control system outperformed the companies that had implemented ECL strategy. Also, the ZD strategy differs from ECL strategy in control system, the criteria of performance evaluation and feedback frequence variable. There is no difference in quality performance monitoring and communication variable. From this results, although many companies have strived for continuous improvement of quality, it was restricted in improvement activities that dont's required much investment cost, quality performance monitoring and communication.

The relationship between R&D Polices(R&D subsidy, tax incentives) and firm R&D expenditures is analyzed through firm's profit maximization function. As a result, the relationship between R&D policies and fmn R&D expenditures is determined by the relationship between firm R&D expenditures and market price. In case of major innovation which cause the fall of market price, the elasticity R&D subsidy and firm R&D expenditures is negative(substitution). In case of minor innovation which cause the rise of market price, the elasticity R&D subsidy and firm R&D expenditures is positive(complement). Tax incentives is bring about the increase of firm R&D expenditures. R&D subsidy and tax incentives are substitutively influenced at firm R&D expenditures.

The main objective of this study was to investigate the customer's satisfaction level with the digital relationship model of Banco do Brasil Exclusive Business Offices situated in Rio Grande do Sul. Banco do Brasil is one of the largest Brazilian and global financial institutions and conducted a restructuring customer's relationship model since 2015, creating new specific service structures for certain segments, among them exclusive offices. This research had a qualitative step with an internal documentary analysis about the company and a semi-structured interview with manager's offices, in order to check the strategy and the foundations of business model, as well as identify perceptions and the difficulties in implementing this new structure. The quantitative step held the findings about customer satisfaction level in relation to the quality of services provided by offices, through an electronic survey based on the Servqual Scale developed by Parasuraman et al. (1988), which measures the difference between customer's expectations and perception in five dimensions: tangibility, reliability, understanding, safety and empathy. The results shown that Banco do Brasil customers' are satisfied with services offered through the digital model and the new business structure, in which is offered a humanized service together with the best technology. It was found, also, that digital probably would not replace the physical world, but they complement one another. Digital offices and physical agencies will coexist, improving value proposition delivery and better customers experience, satisfy them and build their loyalty.

The purpose of this paper is to attempt the analysis of the 'Positivist' School and the 'Interpretative' School to the Relationship between Theory and Method, Using examples from Criminological Research. The differences between approach of the positivist school and interpretative school are often made very difficult to make an approach. What are more to focus on are the relationships between quantitative research and positivism and qualitative research and interpretative paradigms are often presented as essential connections. Therefore, it is a lot more difficult to imply an appropriate research method and process depends on the subject and field of the research topic. The differences between types of research and also the connections which are made between types of research and theoretical paradigms portray a very simple picture. The danger of this is that two readily available set of research methods and assuming that positivist and interpretative research style represent competing approaches and also that they present 'either-or' alternatives as to strategies of research. For example, in some instances positivist and interpretative's methods do represent alternatives but in some case, positivist and interprativist each other can complement about each other's defects in terms of use of methodology. Though depending according to the specialist of the topic, it needs sensitivity to the potentials and the contributions of different styles of data and different methods of information collection and analysis to the criminological issues under test and to the theoretical questions being asked of them.
