Purpose : This study is to confirm the relation of the value orientation of the nursing unit manager and the job satisfaction and organizational commitment of the nursing unit nurse. Method : We used the systematic questionnaires as a study tool. The contents were composed of 46 questions in total such as 4 questions of general feature, 23 value-oriented questions, 10 job satisfaction questions, and 9 organizational commitment questions. The period of data collection was from August to September 2000. Result : 1) The value of flexibility was 3.82 points (${\pm}.3788$), which is above average. The values of equalitarianism was 3.37 points (${\pm}.4422$), which is above average. 2) The leadership pattern according to the value orientation perceived by the head nurses in 6 clusters has been divided into 3 patterns of change-oriented leader, task-oriented and stability-oriented leader. 3) The nurses who worked with the change-oriented leader showed higher values of job satisfaction (F=5.941, p=O.003), and affective commitment (F=5.793, p=O.003) than those who worked with the stability-oriented leader. Conclusion : As revealed in this study, we think that we have to consider that the change-oriented leader can produce higher performance of an organization than the stability-oriented leader, and write the basic data for the educational courses of leadership development or workshops etc. in order for the nursing unit managers to play their roles for the effective ward-unit management.

In this paper, we propose a new image descriptor, that is, a rotation invariant histogram of oriented gradients (RIHOG). RIHOG overcomes a disadvantage of the histogram of oriented gradients (HOG), which is very sensitive to image rotation. The HOG only uses magnitude values of a pixel without considering neighboring pixels. The RIHOG uses the accumulated relative magnitude values of corresponding relative orientation calculated with neighboring pixels, which has an effect on reducing the sensitivity to image rotation. The performance of RIHOG is verified via the index of classification and classification of Brodatz texture data.

In this paper, we deal with the problem of modeling of agent-based robot manufacturing cell. Its role is becoming increasingly important in automated manufacturing systems. For Object Oriented & Queueing Petri Nets (OO&QPNs), an extended formalism for the combined quantitative and qualitative analysis of different systems is used for structure and performance analysis of mobile robotic cell. In the case study, the OO&QPN model of a mobile robotic cell is represented and analyzed, considering multi-class parts, non-preemptive priority and alternative routing. Finally, the comparison of performance values between Shortest Process Time (SPT) rule and First Come First Serve (FCFS) rule is suggested. In general, SPT rule is most suitable for parts that have shorter processing time than others.

As the environment related to hospital operation has changed very competitively in recent years, a need to reform the hospital management is ever growing. For that reason, it has become more urgent and strategically important for us to diagnose the organizational culture of the hospitals and to make efforts to change them towards more performance- and customers-oriented one. So far, there have been many studies done on the hospital organizations. However, this research distinctively attempts to base itself on the competing values approach in studying the organizational culture and empirically examine how different profiles of the organizational culture may have an impact on the organizational performances in hospital organizations. The results of this study has showed several interesting findings and posed the discussions to be dealt with. First, most hospitals selected for this research are characterized by the inner-oriented culture with more focused on 'hierarchy' and 'relationship-oriented' culture rather than on 'reform' and 'work-oriented' one. And the strong 'hierarchy-oriented' culture is a very general phenomenon in the sample hospitals. From these findings, we can inference that despite the recent efforts of most Korean hospitals for organizational change and innovation they still have long distance way to go. In addition, another important implications of this research has come from the analysis of the relationships between the cultural profiles and organizational performances. For this purpose, this research has conducted a series of cluster analysis and identified four distinct cultural profiles from the sample organizations. Several major findings are as follows. First, with respect to the dependent variable of 'job satisfaction' perceived by the nurses working in the sample hospitals, we found that the balance of competing organizational values had more positive impact on the job satisfaction. This result confirms the hypothesis of competing values model on the organizational performances. However, such result was not replicated on the other dependent variable, 'patients' satisfaction'. The reasons for these results and other discussions including the limitations of this study are suggested.

In a field-oriented vector-controlled permanent magnet synchronous motor (PMSM) control system, the d-axis current control loop can offer a free degree of freedom which can be used to improve control performances. However, in the industry the desired d-axis current command is usually set as zero without using the free degree of freedom. This paper proposes a method to use the degree of freedom for control performance improvement. It is assumed that both the inner loop proportional-integral (PI) current controller and the q-axis outer loop PI speed controller are tuned by the well-known tuning rules. This paper gives an optimal d-axis reference current command generator such that some useful performance indexes are minimized and/or a tradeoff between conflicting performance criteria is made. This paper uses a differential evolution algorithm to autotune the parameter values of the optimal d-axis reference current command generator. This paper implements the proposed control system in real time on a Texas Instruments TMS320F28335 floating-point DSP. This paper also gives experimental results showing the practicality and feasibility of the proposed control system, along with simulation results.

Purpose - Environmental issues, climatic changes, and greenhouse gases are problems to be solved at a global level. With an increased emphasis on the environmental and social responsibility of the management of companies, the manner in which companies approach quality-oriented culture and their individual sustainability management are being discussed as truly important issues to help them secure their competitiveness and growth strategies. This study proposes strategic directions to help manufacturers not only in expanding their competitive quality-oriented company culture but also in strengthening their sustainability management abilities. This study conducts a literature review and empirical research to examine how significantly the variables of a quality-oriented company culture, customer-centered management, and process-centered and supply chain management-centered cooperation affect sustainability management performance in relation to economic profitability, environmental integrity, and social responsibility. Research design, data, and methodology - To verify research models and hypotheses, the study examined 170 companies using a questionnaire survey conducted over six weeks, and involved the performance of data analysis on 146 samples. Questionnaire responses were calibrated based on a Likert scale. The study used the Smart PLS 2.0 program designed for PLS (partial least squares), an analysis instrument of SEM (structural equation modeling). The study then verified empirical research hypotheses working on reliability analysis, validity analysis, factorial analysis, and path analysis. Results - Among the nine hypotheses, four are accepted and the rest are rejected. A quality-oriented company culture focusing on customer-centered management significantly influenced the maintainability management performance of environmental integrity and social responsibility, while economic profitability was dismissed. A process-focused quality-oriented company culture was significantly concerned with economic profitability but not with environmental integrity or social responsibility. A supply-chain cooperative company culture had a significant effect on economic profitability but not on environmental integrity or social responsibility. Conclusion - This study proposes strategic directions to help manufacturers expand their competitive quality-oriented company culture as well as strengthen abilities with sustainability management. It conducts a literature review and empirical research to examine how significantly the variables of quality-oriented company culture, customer-centered management, and process-centered and supply chain management-centered cooperation affect sustainability management performance in relation to economic profitability, environmental integrity, and social responsibility. There are two main conclusions. First, companies should consider the need for social responsibility management and environmental transparent management-focused maintainability management as avenues to create new markets and business, thereby helping the companies secure a reputation for having a customer and process-centered quality-oriented company culture by creating shared values between supply chains and enabling win-win situations through cooperation. Second, we are marching towards a creative win-win era from a society of conflicts and ruptures. Companies should understand that social responsibility management and supply chain management (SCM)-focused cooperation are the foundations of sustainable development, as they try to improve their culture while pursuing both win-win relationships with interested parties and equity in various conflictive relations.

Object-oriented analysis-synthesis coding subdivides each image of a sequence into moving objects and compensates the motion of each object. Thus it can reconstruct real motion better than conventional motion-compensated coding techniques at very-low-bit-rates. It uses a mapping parameter technique for estimating motion information of each object. Since a mapping parameter technique uses gradient operators it is sensitive to redundant details and noise. To accurately determine mapping parameters, we propose a new analysis method using integral projections for estimation of gradient values. Also to reconstruct correctly the local motion the proposed algorithm divides an image into segmented objects each of which having uniform motion information while the conventional one assumes a large object having the same motion information. Computer simulation results with several test sequences show that the proposed image analysis method in object-oriented analysis-synthesis coding shows better performance than the conventional one.

Globalization and the emergence of new markets has placed increased emphasis on cross-cultural sales and marketing research. Despite considerable advances in the personal selling literature, little is known about the cross-cultural transferability of key constructs. Given the degree to which well-accepted relational sales behaviors such as ASB and customer oriented selling reflect Western values such as individualism and low uncertainty avoidance, the relative efficacy of such practices in alternative cultural context is less clear. Using a Korean sample, our results confirm the beneficial direct effects of these relational selling practices upon performance. However, we also find strong workgroup interdependence diminishes the effects of ASB and that performance fully mediates the relationship between both sales behaviors and job satisfaction. In contrast to prior results, we find female salespeople and those newer to their position demonstrate stronger ASB.

With a sample of 147 Korean small and medium size companies, this study examined the relationships among degree of information orientation, corporate culture, degree of information management implementation and selected business performances in the process of implementing IMS improvement programs, such as IMS(Information Management System). Information orientation is defined as company-wide understanding and implementation of the underlying philosophy, principles, approached, and tools of information improvement programs. It is assumed that successful implementation of information improvement programs requires a information-oriented mind-set of the employees. The key elements of information orientation include continious improvement structured processes, organixation-wide participation and customer-focused spirit. Culture id defined as the value and beliefs of em organization that shape its behavior. It is also assumed that successful implementation of information improvement programs require strong support from s corporate culture that emphasizes cintinious improvement. Adopting the competing values model of Quinn and McGrath(1985), corporate culture is classified into 'flexible' versus 'controlled culture' and 'outer-directed' versus 'inner-directed culture'. Fitness was defined through the relationship between levels of information oriented and types of corporate culture. The results were as follows. First, it was found that when a company with high information orientation promoted information innovation programs, such as IMS, it reported higher degree of information management implementation and improvement in business performances. Second, the results showed the importance of 'flexible culture' and 'outer-directed culture' in performing information, innovation. Regarding the types of corporate culture, the analysis found that developmental culture, rational culture and group culture were effective. Third, companies with high information oriented and flexible culture or companies with high information orientation and outer-directed culture reported the highest implementation in Information management activities. Fourth, the results showed that the level of information management implementation had a mediating effect on the relationship between information orientation and business performance. It was also found that enhanced non-financial performance led to the improvement of financial performance. This study attempted to exaime the factor that lead information management program to success. In order to reach success, first, it is suggested that companies have positive mind set toward continious information improvement. Secondly, it is recommended that a flexible and outer-directed culture appropriate for continious information improvement is cultivated.
