With new competitive environments, innovation is more necessary to survive severe competitions than ever. However, most Small and Medium(SM) businesses are used to be short of professional staffs, money and equipments for performing various innovations(ie., technological or administrative innovation, product development or Process development, and radical or incremental innovation). Many students have suggested that incremental innovation is more adequate than radical innovation in SM business. The purpose of this paper is to find antecedent factors In promote employees' Incremental Innovation Activities(IIA), In analyse moderating effects of ability and attitudes, and to test the difference of IIA-level by ability(or attitudes) and 11 independent factors. Each IIA-level by 5 variables of 11 independent variables-job variety, importance, identity, communication, performance dependency-is found to be significantly different in high-ability group affirmative-attitude group.

The rapidly changing environments of today's hospitality industry lays more and more emphasis on the management of food & beverage sector. Hotel restaurants changes their menus 2 times a year. But they tend to modify or complement old items, or imitate other restaurants'menus, rather than try new ones. In addition, the change cycles are determined without any systematic and scientific criteria. Based on the survey, a plan for managing menu change cycles is proposed. The proposed plan is summarized as follows: First, the survey result demonstrates that the appropriate frequency of menu changes is: twice a year for the fixed menu; four times for the seasonal menu; four times for the promotion menu; twice for the business menu; and, three times for the event menu. Second, under the management maintained by consistent monitoring of menu change. Third, menu change should be managed through the menu analyses on its profitability, popularity, and the potential for further growth. Fourth, menu change should be managed through the periodic investigations of the tastes and preferences of the customers. fifth, a unique system for the menu change should be constructed by analyzing of other competitive restaurants or restaurant chain stores.

World Wide Web(Web) supports bi-directional communication between corporations and consumers. In the year of Electronic Commerce, close relationships with consumers are more emphasized for corporations. Nowadays, corporations compete with corporations which are located in whole world through the media called Internet. In this competitive environment, to attract consumers' attentions, it is required to develope corporations' Web sites in the way to stimulate consumers' purchase intentions. To verify the elements needed to stimulate consumers' purchase intentions factors which influence consumers' purchase intentions were analyzed. Adaptation, shopping convenience and assurance-reliability were found to be positive factors for consumers' purchase intentions. It was also found that consumers' purchase intentions in electronic commerce market are influenced by previous shopping experiences. Consumers who have previous shopping experiences are mainly influenced by good delivery systems and shopping environments while who have no experiences are influenced by consumers' risks such as performance risk and personal and privacy risk when they intend to purchase products or services.

Recent competitive and technological changes during the past decade have accelerated the need for better capital recovery methods. Competition and technology have together shortened the expected lives of property which could not have been forecasted several years ago. Since the usage of technological growth models has been prevalent in various technological forecasting environments, the various forms of growth models have become numerous. Of six such models studied, some models do significantly better than others, especially at low penetration levels in predicting future levels of growth. A set of criteria for choosing an appropriate model for technological growth models was developed. Two major characteristics of an S-shaped curve were elected which differentiate the various models; they are the skewness of the curve and underlying assumptions regarding the variance of error structure of the model.

Due to the price and performanceof uniprocessor workstations and off-the shelf networking, network of workstations(NOW) ae now a cost-effective parallel processing platform tht is competitive with supercomputers. Meanwhile, current network fiile system protocols rely heavily on a central server to coordinate file activity among client workstations. This central server can become a bottleneck that limits scalibility for environments with large numbers of clients. In this paper, we propsoe a highly reliable and effective software RAID file system on the network of workstation environment. We present results form a trace-driven simulation study that shows that the designed software RAID file system is more effective in the aspect of elapsed time when compared with client/server file systems.

In this study, the competitive development of leaf in Amaranthus and Chenopodium were invesitgated by the complemented plastochron index. The value of PI for Amaranthus was not varied with competional ratios, while for Chenopodium it was varied. Namely in Chenopodium, the plastochron 1 was increased as competitional combinations, the plastochron 2 was decreased. These results indicated Amaranthus had advantage in competition over Chenopodium. It is surmised that these results were exhibited differences in photosynthetic pathway between Amaranthus (C4 plant) and Chenopodium (C3 plant). The linear patterns were clearly demonstrated by the differences in leaf arrangement between Amaranthus (alternate type) and Chenopodium (opposite type). From these resultss, use of plastochron seems to a useful means of evaluating plat response to various environments.

DNA computing-inspired pattern classification based on the hypernetwork model is a novel approach to pattern classification problems. The hypernetwork model has been shown to be a powerful tool for multi-class data analysis. However, the ordinary hypernetwork model has limitations, such as operating sequentially only. In this paper, we propose a efficient implementing method of DNA computing-inspired pattern classifier using GPU. We show simulation results of multi-class pattern classification from hand-written digit data, DNA microarray data and 8 category scene data for performance evaluation. and we also compare of operation time of the proposed DNA computing-inspired pattern classifier on each operating environments such as CPU and GPU. Experiment results show competitive diagnosis results over other conventional machine learning algorithms. We could confirm the proposed DNA computing-inspired pattern classifier, designed on GPU using CUDA platform, which is suitable for multi-class data classification. And its operating speed is fast enough to comply point-of-care diagnostic purpose and real-time scene categorization and hand-written digit data classification.

Purpose : The purpose of this paper is to analyze the characteristics of hospital architecture constructed in each periods and identify the changing process of hospital architecture in Korea since 1945. Methods : Literature review was conducted while the data of hospitals had been collected and the subject of investigation were selected. The important point of analysis is about design conception, site plan, block plan and hospital form. Results : The characteristics of hospital architecture are identified in each periods. Developed by private sector, hospitals have enlarged their beds and sizes under the competitive environments. In terms of size and external shape, vertical form has become a dominant scene of hospital forms in Korea. Among the dominance of tower-on podium, various block plans have been adopted with hospital streets. Also a few cases of horizontal disintegrated form was introduced. Implications : This paper could be the basic data to organize the history of Korean Hospital Architecture, and insufficient data should be supplemented continuously.
