An estimation scheme is used for solving two practical problems of the single current sensor technique. To improve the effect of parameter uncertainties the method that identifies motor parameters for AC motor drive systems using the single current sensor technique is presented. And the parameter identification error and its cause atre examined. It gives good performances for identify in parameters and reconstructing phase currents.

A research on differential effects of task and relationship conflicts claims positive effects of task conflict on innovation performance and negative effects of relation conflict on innovation performance. Yet, given the intimate interconnectedness of task conflict and relation conflict, task conflict, which has a beneficial impact on innovation performance, may have adverse effects on innovation performance as it goes through the process of being transferred to relation conflict. That necessitates the need for a way of management that can undermine the process of transference of task conflict to relation conflict, and team identification, which is a social identity of an individual and also a sort of positive, affective or cognitive bonds of such individual toward the team, can be an effective way of managing conflict. The research, which was conducted based on materials collected from 213 employees, confirms that such theory holds true for the real-life business environment. Based on the findings, this study suggested implications and directions for future research.

In this paper a discrete time model for the identification of nonlinear vibration system with stick-slip friction is proposed. The proposed model can handle the highly nonlinear behavior of the friction such as stick-slip phenomenon and Stribeck effect. The basic idea of the proposed model is as follows : If the nonlinearity of the system can be predicted as a simple function then this nonlinear function term cab be directly used in the discrete time model. By doing this the number of nonlinear terms in the model can be much less than those of NARMAX model which is widely used nonlinear discrete model. The simulation result shows that the proposed model can estimate the response of the nonlinear vibration system with stick-slip friction very well with less computational effort.

In this paper a new multi-step damage detection approach is provided. In the first step, condensed modal residual vector based indicator (CMRVBI) has been proposed to locate the suspected damaged elements of structures that have rotational degrees of freedom (DOFs). The CMRVBI is a new indicator that uses only translational DOFs of the structures to localize damaged elements. In the next step, salp swarm algorithm is applied to quantify damage severity of the suspected damaged elements. In order to assess the performance of the proposed approach, a numerical example including a three-layer square laminated composite plate is studied. The numerical results demonstrated that the proposed CMRVBI is effective for locating damage, regardless of the effect of noise. The efficiency of proposed approach is also compared during both steps. The results demonstrate that in noisy condition, the damage identification approach is capable for the studied structure.

We investigate the role of contact location information on the perception of local features during contour following in a virtual environment. An absolute identification experiment is conducted under force-alone and force-plus-contact-location conditions to investigate the effect of the contact location information. The results show that the participants identify the local features significantly better in terms of higher information transfer for the force-plus-contact-location condition, while no significant difference was found for measures of the efficacy of contour following between the two conditions. Further data analyses indicate that the improved identification of local features with contact location information is due to the improved identification of small surface features.

Objective : The purpose of this paper is to report the effect of Danggwihweyeokgaohsuyu-saenggang-tang(DHGOST) on primary dysmenorrhea from the disease pattern identification diagnostic system based on Shanghanlun provisions. Methods : According to a disease pattern identification diagnostic system based on Shanghanlun provisions, the patient was diagnosed with 'Reverting Yin Disease'. She took DHGOST for 75 days. This paper evaluated the results of treatment by Measure of Menstrual Pain(MMP) and Menstrual Symptom Severity List(MMSL) Results : The MMP score was declined from 8.3 to 3.5. And the MMSL score was declined from 46 to 38. Conclusions : This case study suggests that DHGOST has effectiveness on primary dysmenorrhea who is diagnosed with 'Reverting Yin Disease'.

Objective : The purpose of this paper is to report the effect of Daehamhyung-tang(DHHT) on tinnitus with panic disorder from the disease pattern identification diagnostic system based on Shanghanlun provisions. Methods : According to a disease pattern identification diagnostic system based on Shanghanlun provisions, the patient was diagnosed with 'Taeyang-byung Gyeolhyung'. He took DHHT for 82 days. This paper evaluated the results of treatment on tinnitus by Tinnitus Handicap Inventory(THI) and Verbal Numercial Rating Scale(VNRS). To assess the mental state of anxiety, this paper used Hamilton Anxiety Rating Scale(HAM-A) Results : The THI score was declined from 58 to 6 And the VNRS score was declined from 6 to 1. HAM-A score was declined from 28 to 3. Conclusions : This case study suggests that DHHT has effectiveness on a patient suffers from tinnitus with panic disorder and diagnosed with 'Taeyang-byung Gyeolhyung'.

This research aims to provide empirical basic data for the development of local communities through the establishment of efficient strategies for the formation of positive relations between the club and the region through the Creation of Shared Value (CSV) activities. We come up with the results of this study to show that CSV, social problem orientation, and core competency utilization affect the team trust of local community, and that CSV, long-term orientation, social problem orientation and core competency utilization affect community identification. The research should enhance the value of professional sports teams that promote their own path to self-sustaining as a single independent business area, and identify their trust through CSV activities for co-prosperity with their local communities, and thus their relationship with the community. Therefore, various strategies and efforts will ultimately increase the team trust and community identity of local residents in professional volleyball teams, while at the same time gaining positive effects on professional volleyball teams.

The purpose of this study was to verify the effects of group psychotherapy on recovery of self-identification with the unemployed homeless. To this end, 28 attending welfare-centers in Seoul area were sampled to be subject to 12 rounds of group psychotherapy for 6 weeks. In order to determine the effects the, test, preliminary test and post-program test were conducted. Every round of the program activities were video-taped, while being observed. The results of this study were as follows. First, the group psychotherapy influenced positive effect. Especially, the unemployed homeless had a opportunity of self-comprehension, self-insight, catharsis, etc. Second, during group psychotherapy, individual characteristics of the unemployed homeless were determined. Third, during group psychotherapy, the unemployed homeless complained about family problem, health, alcoholism, etc.
