This paper presents a technique for estimating distribution of data stored in a database. This technique is very useful for accurate selectivity estimation, which is essential in query optimization and physical database design. To maintain data distribution, we employ the directory of the multilevel grid file, a multidimensional dynamic file organization. The major advantage of our technique is that data distribution information is maintained dynamically in the multilevel grid file. In contrast, other static methods such as the histogram method use static date structures, which requires periodic restructuring. Furthermore, we propose a method for keeping the abstract information of data distribution in main memory. This is advantageous in the situation where the size of main memory is not sufficient. Finally, We also suggest formulas for calculating selectivies of various queries based on our data distribution information.

Reengineering, also known as a business process redesign, involves a fundamental rethinking, and often a radical redesign, of an entire business process or a set of process to achieve dramatic improvements. The central paradox of reengineering is that its own advantages constitute the greatest threat to its success. For reengineering to be the right choice, the organization must have real capacities to embrace changes across the board. The key is to begin with, and to preserve, a vision of the new order, which drives this structured approach, and is in turn calibrated by that approach. However, in most cases of these calibrations, the empirical evidences on the effect of determinants in the reengineering are required. Seemingly, the research results in this area are scarcely verified. This article tried to search the effect of four dimensions of the reengineering toward the performance of reengineering. The results showed that the factors of the organization behavior and of the methodology/operation had more affected on the performance.

For this study we investigated situation of domestic standardization in contact lens field. The rate of contact lens wearing have increased lately, nevertheless Korean Industrial Standard just has been translated into the regulations of ISO(International Organization for Standardization), and it has been applied. Moreover there is not any the domestic original regulation yet. Therefor, for this study we investigated current situation of the ISO in contact lens field and fitness of standard in our present actual condition. Also, by grasping the problems which it follows.

In this paper, we investigate the influence of factors on the firm, industry, and country levels on the new product development performance (NPD) of manufacturing firms in advanced economies. The resource-based view, industrial organization theory and institutional theory have established that firm-, industry- and country-level factors are all relevant for the NPD of firms. However, little is known about the relative importance of factors at the three different levels across countries, as prior studies on firms' NPD have focused on specific countries and levels of analysis. Our analysis of survey data from 1,437 manufacturing firms in nine advanced OECD countries shows that while firm-level factors are generally better predictors of firms' innovativeness than either industry- or country-level factors, the results strongly differ across countries, indicating that the relative importance of antecedents of innovativeness is country-specific rather than universal.

Using a sample of 180 managers in small and medium sized organizations in Chungcheong and Southern Gyeonggi Province, we proposed that official communication channel on safety issue will influence managers' safety climate, empathy (safety climate), and eventually occupational accidents. The results supported our hypotheses, showing managers concern about their employees' safety issue when the organization officially emphasize on safety issue. At the same time, it also tells that managers are emphatic on their employees regarding occupational accidents when it comes to safety climate.

The organization of business included many a factors that gave rise to the stress. The modem peoples in this organization lived in the flood of the stress. Job stress was an important factors which injured of the employee health, the employee health injured reduce the organizational function. The factors such as personal differences, stressors, personality, cognitive traits etc. should be considered in the study of job stress. The cognitive appraisal is an important factor in the study of job stress and a process of coping strategy. Job stress can be controlled and coped by organizational and personal ability. The coping strategy of job stress is also determined by the personal differences rather than by the intensity of stress symptoms. In copying the stress, to be considered the factors such as interpersonal correlation, organizational climate, career development, job redesign, selection and placement, training. However, these factors should be managed in the scientific, objective, reasonable manner effectively.

The main purpose of this study was to examine the determinants of organizational form in the sport organization. This study found that the leader's quality had positive influences on the personality, knowledge ability, and change management. Based on the analysis of three hundred fifty cases, the following results were found. First, the leader's quality and personality had the significant effects on knowledge-Based management in the sports organizations. Second, the leader's knowledge competence and the transformative leadership had the significant effects on knowledge-Based management in the sports organizations. Third, the leader's knowledge :management had the significant effects on organiztional behavior in the sports organizations.

The purpose of study was to test the effects of CEO' transformational leadership and learning organization on innovative behavior in the Knowledge-based Service Organization showing the characteristics of convergence service and the moderating role of learning organization between transformational leadership and innovative behavior. For this study, the data were collected from 348 Knowledge-based Service industrial employees in metropolitan area by using structured questionnaires. Collected data were analyzed by hierarchical regression technique. The results showed that both of CEO' transformational leadership and seven learning organization building factors had a positive effect on employees' innovative behavior. And also found out the only four out of the seven learning organization building factors, namely 'Create continuous learning opportunities', 'Promote inquiry and dialogue', 'Encourage collaboration and team learning', 'Provide strategic leadership for learning' had the moderate roles between CEO's transformational leadership and employees' innovative behavior. The theoretical and practical implications of the findings were discussed and the directions for future research were presented.

The author propose a method to realize a self organization in the artificial system. In self organizing system, sub-systems are not constructed as functional parts of the system but cooperate with one another to realize the total system. Each sub-system obtains the local purpose from the global purpose by learning. This function is realized by using a neural network. The validity of this method is confirmed by some simulations.
