본 연구에서는 심리적 계약이론, 사회적 정체성 이론, 효과계층모형을 이론적 근거로 하여 광고가 종업원의 조직 동일시에 미치는 영향에 관한 구조적 모형을 제시하였다. 연구결과, 광고 정확성은 광고태도에 유의한 영향을 미치는 것으로 나타났으나 광고 관련성은 유의한 영향을 미치지 않았다. 그리고 광고태도는 조직 동일시에 긍정적인 영향을 미치는 것으로 나타났다. 특히 본 연구의 결과는 광고에 대한 종업원의 평가가 광고태도를 매개로 하여 조직 동일시에 영향을 미치는 관계를 밝혔다는 점에서 이론적 의의가 있다.

This study sets out to verify the moderated mediation of followers' identification with the leader on the indirect effect of authentic leadership on organizational cynicism via psychological contract breach. A total of 279 responses from employees at companies with more than 500 employees and of diverse industries were used for analysis. Our findings showed that authentic leadership (X) had a negative indirect effect on organizational cynicism (Y) via psychological contract breach (M), and that this indirect effect was negatively moderated by identification with the leader, thereby identifying its role as a moderating mediator. Further verification revealed that the indirect effect ($X{\rightarrow}M{\rightarrow}Y$) was conditional upon the value of the moderating variable, where identification with the leader had a significant effect in the 25%, 50%, 75%, 90% levels, but not in the 10% level. The findings of this research empirically verified that greater exertion of authentic leadership lowers psychological contract breach among organization members and, consequently, organizational cynicism. In particular, this effect was stronger when the organization member identified him/herself more strongly with the leader. Our findings extend the body of knowledge on the relationship between authentic leadership and organizational cynicism and expands the possibilities for future research.

Purpose: Crowdfunding can be a complementary channel in which start-ups or small companies can obtain financial help and take advantage of exploiting the online potential. To activate crowdfunding, it is necessary to consider a consumer's empathic responses. This article examines the role of empathy in the crowdfunding channel platform. We adopted the identification-commitment model to prove the role of empathy. Research design, data, and methodology: Participants were asked to read the charitable crowdfunding campaign. More than 300 young adults completed an online questionnaire and we analyzed it with structural equation modeling (SEM). To find out the role of empathy, we postulate several models which use empathy variable for different purposes. Results: We conclude that empathy has the role of moderator in the identification-commitment model. This means the high empathic response helped the relationship between identification and commitment. However, low empathic response can negatively influence the process of identification to commitment. Conclusions: This study found that virtual empathy is positively related to crowdfunding participation if we can elevate empathy in the crowdfunding channel platform. The findings also show that we need to consider empathic response when we want to raise funds for specific projects such as protecting the natural environment.

The purpose of this study is as follows. First we investigate the relationship between contact with foreign managers (CFM) of host country nationals (HCNs) working at MNC subsidiaries and their organizational identification with MNC (OIM). Second we examine the moderating effect of MNC subsidiary localization (MSL) on the relationship between CFM and OIM. For this purpose, we set hypotheses on the relationship among CFM, OIM, and MSL. To verify theses hypotheses, we conducted hierarchical regression analysis on the data from 374 HCNs in 56 MNC subsidiaries. The results of this study are as follows: Frist, CFM positively affects OIM. Second, there is a significant moderating effect of MSL on the relationship between CFM and OIM. Our findings have critical implications in that a subsidiary-level variable that has a significant impact on organizational identification with MNC is presented and in that specific managerial guidelines for subsidiaries can be drawn.

This report proposes a novel method of identification of continuous time-delay systems from sampled input-output data. By the aid of a digital pre-filter, an approximated discrete-time estimation model is first derived, in which the system parameters remain in their original form and the time delay need not be an integral multiple of th sampling period. Then an identification method combining the common linear least squares(LS) method or the instrumental variable(IV) method with the genetic algorithm(GA) is proposed. That is, the time-delay is selected by the GA, and the system parameters are estimated by the LS or IV method. Furthermore, the proposed method is extended to the case of multi-input multi-output systems where the time-delays in the individual input channels may differ each other. Simulation resutls show that our method yields consistent estimates even in the presence of high measurement noises.

It is important to express the specific growth rate of a fermentation reaction as a function of substrate and product concentration in developing bioprocess automation techniques such as modeling of the reactor and controlling it via an advanced control scheme. Typical methods of identification utilize graphical representation of the rate constant data or nonlinear regression with an appropriate noise filter. But the former method fails when the data are erroneous and the latter are mathematically complicated to apply in the field. Neural network is another candidate for the identification from time series data since it is insensitive to the random data error and easy to implement. In this study, we will develop a neural network method of specific growth rate estimation from the time series state variable data and test the performance.

This paper identifies a linear combustion model of Refuse Incineration Plant(RIP) which characterizes its combustion dynamics, where the proposed model has thirteen-inputs and one-output. The structure of the RIP model is given as an ARX model which obtained from the theoretical analysis. And then, some unknown model parameters are decided from experimental input-output data sets, using system identification algorithm based on Instrumental Variables(IV) method. In result, it is shown that the proposed model well approximates the input-output combustion characteristics riven by experimental data sets.

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.

Reengineering to object-oriented system is needed to maintain the system and satisfy requirements of structure change. Target systems which should be reengineered to object-oriented system are difficult to change because these systems have no design document or their design document is inconsistent of source code. Using design document to identifying objects for these systems is improper. There are several researches which identify objects through procedural source code analysis. In this paper, we propose automatic object identification method based on clustering of VTFG(Variable-Type-Function Graph) which represents relations among variables, types, and functions. VTFG includes relations among variables, types, and functions that may be basis of objects, and weights of these relations. By clustering related variables, types, and functions using their weights, our method overcomes limit of existing researches which identify too big objects or objects excluding many functions. The method proposed in this paper minimizes user's interaction through automatic object identification and make it easy to reenginner procedural system to object-oriented system.
