The purpose of this study is to understand the characteristics of intergenerational consumption-oriented attitude and consumer role performance. Major findings are as follows; 1) There is significant difference between the consumption-oriented attitudes of respective generations. The means of New generation are higher than the other generations especially in amusemental consumption-oriented attitude and tenacious consumption-oriented attitude. Baby-boomer generation is more interested in consumption than any other generation and has a rational consumption-oriented attitude. The older generation is passive to consumption and their consumption-oriented attitudes are those of amusement. 2) There is also the significant gap between the consumer role performance of generations. The means of new generation and older generation are higher in consumer role performances than other generations and are especially doing better in the roles of estimator and manager. 3) consumption-oriented attitudes illustrate the variation of consumer role performance and the stronger the rational or tenacious consumption-oriented attitude, the higher the consumer role performance and the higher the rational or tenacious consumption-oriented attitude, and the lower the passive consumption-oriented attitude, the higher the consumer performance. In purchaser and manager role, the more positive the consumption and the higher the rational consumption-oriented attitudes, the better the consumer role performance.

This study was to examine the degree of market orientated effort by hospital type and size,. and analyzed the moderating effect of environments between market orientation and it's performance. First, there was no significant differences by hospital type, such public hospital, university hospital, and private hospital. However, the orders of market orientation implementation was university hospital. private hospital, and public hospital This finding suggest that university hospital and public hospital, should be market-oriented, or customer-oriented more now, relatively. Second, there were no significant differences in marketing as management policy by hospital types, i.e. public, university or private sector hospitals. However, as to the intensity of the implementation of the market-oriented approach, private hospitals came first, followed by the university hospitals, then the public ones. This finding suggests that university and public hospitals should be more market or customer oriented to compete in the market. Third, only the competitive environment does active moderating roll on hospital performance. The competitive environmental factor forces the organization to be more market oriented. This means the more you are positively situated in the competitive environment, the more you are looking for a market oriented approach. You become more aware of the value of customers and you become more focused on the customer satisfaction and thus become more patient oriented in every facet of decision making. And market oriented hospitals recognize the importance of utilization of high tech medical treatment skills and equipment in patient care. Fourth, according the analysis, market oriented effort gives more influence on hospital performance than the environmental factors. This means that the market oriented effort should become a culture of the hospital which seeks to out distance themselves from its competitors.

In this work, we propose a concurrency control scheme in object-oriented database (OODB). Since an OODB provides complex modeling power than the conventional relational databases, a concurrency control technique in OODB is also rather complicated and has influence on the overall performance. Thus, it is very important to develop a concurrency control technique with less overhead. The proposed scheme deals with class hierarchy that is a key concept in OODBs. The proposed scheme is developed on implicit locking scheme. Also, the proposed scheme is designed using data access frequency in order to reduce locking overhead than implicit locking. It means that, if access frequency information is not available, the proposed scheme works just like the existing implicit locking, In our work, the correctness of the proposed scheme is proved. The performance is analyzed depending on access types. Also, it is proved that our scheme performs works much better than the implicit locking does.

The purpose of this study was to investigate the influence of the leadership of head nurses on the job satisfaction and job performance of staff nurses. The leadership styles of head nurses were classified to "authority-oriented" and "benevolence-oriented" based on korean traditional culture. The subjects of this study were 450 staff nurses working at medical-surgical units, intensive care units, emergency units of general hospitals in Kyungbuk area. Data were collected from March 13 to March 25 with several scales for the measurement of leadership styles of head nurses, job satisfaction and job performance of staff nurses. The Cronchbach alphas for the scales were. 79 in "authority-oriented" leadership style, 90 in "benevolence-oriented" leadership style, .91 in job satisfaction, .97 in job performance. Data were analyzed with SAS program using statistics of percentage, means, standard deviation, Pearson correlation, ANOVA and ANCOVA. The results were : 1. There were significant correlations between benevolence-oriented leadership style and job satisfaction, job performance of staff nurses(r=.24, p=.000 ; r=.12, p=.008), authority-oriented leadership style of head nurses and job satisfaction of staff nurses(r=.12 ; p=.024). 2. There were significant differences in job satisfaction of staff nurses by age and clinical career(F=10.36, p=.000 ; F=7.63, p=.000). Also there were significant differences in job performance of staff nurses by age, religion, marriage and clinical career(F=17.79, p=.000 ; F=2.89, p=.035 ; F=4.41, p=.036 ; F=14.33, p=.000). 3. There was significant differences in job satisfaction by the leadership style of head nurses. The job satisfaction of staff nurses with benevolence-oriented head nurses was higher than those with authority

Recently, the development of novel control methodology enables us to improve the performance of AC-machine drives by using pulse width modulation (PWM) technique. Usually, the dynamic characteristic of induction motor (IM) has been represented by the 5-th order nonlinear differential equation. This dynamics, however, can be reduced to 3-rd order dynamics by applying direct control of IM input current. This methodology concludes that it is much easier to control IM by means of the field-oriented methods employing the current controller. Therefore a precise current control is crucial to achieve a high control performance both in dynamic and steady state operations. This paper presents an adaptive fuzzy current controller with artificial neural network (ANN) for field-oriented controlled IM. This new control structure is able to adaptively minimize a current ripple while maintaining constant switching frequency. Especially the proposed controller employs neuro-computing philosophy as well as adaptive learning pattern recognizing principles with respect to variations of the system parameters. The proposed approach is applied to the IM drive system, and its performance is tested through various simulations. Simulation results show that the proposed system, compared among several known classical methods, has a superb performance.

Purpose - Recently, domestic pharmaceutical market is growing steadily, but top-tier companies are concentrating on sales growth. In this market, SMEs, which account for more than 80% of the entire market, suffer from the problem of lower margins and increasing inventory costs. According to the government's policy changes related to pharmaceuticals, it is pointed out that the management of existing customers and the control of salespeople are important issues for pharmaceutical companies. This study investigates the effect of the control system on the salesperson in domestic pharmaceutical distribution channel on customer-oriented selling behaviors and sales performance. Research design, data, and methodology - To verify the proposed research model and test hypotheses, the authors selected 244 MR(medical representatives)'s responses which have currently relationship with doctors or pharmacists. This study carefully investigated the reliability, content validity, convergent validity, and discriminant validity of the proposed model. Results - The authors find out the following results: capacity control, activity control, and self control have positive effects on customer-oriented selling behaviors and customer-oriented selling behaviors have a positive effect on sales performance. In addition, we present alternative model to check the direct effect between the control systems and the sales performance, but control system factors except self control have no direct influence. Conclusions - First of all, competency control and activity control increases the customer-oriented selling behavior of the salesperson. This means that the salesperson's sales skill, negotiation skill, customer access skill, presentation ability, monitoring, direction and evaluation are important and it is also important to control activities to check the number of visits to customers, report preparation, and customer service etiquette. Second, the fact that self-control of salesperson affects the customer-oriented selling behavior suggests that self-control is not controlled by external factors but rather establishes short/long-term goals. Therefore, it is important for sales organization to create an environment in which members can induce persistent incentives for self-control. Finally, output control did not affect customer-oriented sales behavior, which is less likely to form confidence or motivation to MRs when output control is perceived as a means of monitoring, supervising, or controlling rather than providing information to salespeople.

Object-oriented databases (OODBs) canbe used for many non-traditional database application areas such as computer-aided design, etc. Usually those application areas require advanced modeling power for expressing complicated relationships among data sets. OODBs have more distinguished features than the traditional relational database systems. One of the distinguished characteristics of OODBs is class hierarchy (also called inheritance hierarchy). A class hierarchy in an OODB means that a class can hand down the definitions of the class to the subclass of the class. In other words, a class is allowed to inherit the definitions of the class from the superclass. In this paper, we present performance evaluation metrics for class hierarchy in OODBs from a concurrency control perspective. The proposed performance metrics are developed to determine which concurrency control scheme in OODBs can be used for a given class hierarchy. In this study, in order to develop performance metrics, we use class hierarchy structure (both of single inheritance and multiple inheritance), and data access frequency for each class. The proposed performance metrics will be also used to compare performance evaluation for various concurrency control techniques.

The purpose of this study is to investigate the effects of the locomotion orientation on salespeople' sales performance with the mediating effect of selling behavior(adaptive selling behavior, SOCO). And we figure out the relationship between customer-oriented selling behavior and adaptive selling behavior because those relationships are not clear. The authors infer research hypotheses based on literature review. We have confirmed the reliability and validity test and those results can be acceptable. Hypotheses test were conducted with structural equation modeling, AMOS. All paths in the research model reasoned by authors have been supported statistically at the significant level. This study with the theoretical implications is as follows. First, this study is the first attempt to investigate the path between locomotion orientation and adaptive selling behavior and SOCO. Secondly, there is an empirical conflict between our study and Franke and Park(2006)'s study. Our study was contradictory to Franke and Park(2006)'s consequences. And so, figuring out clearly those causal paths remains. This study with practical implications are as follows. First of all, the salespeople' selling performance was affected by adaptive selling behavior, customer-oriented selling behavior, and sales-oriented activities, such as the importance of selling behavior once again proven. It is necessary to enhance the capabilities that can be transformed into action appropriate to the needs of customers each sales step-by-step in the process of salespeople for various system through education and incentives, and to interact with customers and understand their customers relative to salespeople will. In order to enhance adaptive selling behavior, the company needs to do educational program and monitoring system with the positional promotion when salespeople get the high adaptive selling behavior. Secondly, the locomotion orientation of the salespeople is to cause this selling behavior. Management style to increase locomotion orientation is needed, which means, salespeople' superior about something should be conducted. In order to stimulate the selling behavior of the salespeople, most supervisors should use some managerial tools such as feedback, engagement, and rewards.
