This study aims to identify various service innovation patterns in the service industry and understand the main differences among them. We attempt to create a new typology of service innovation by analyzing its patterns based on the four major dimensions of service innovation (i.e., service concept, service delivery, customer interaction, and technology). We then investigate whether firms pursuing different service innovation patterns significantly differ from one another in terms of their performance (high and low performance). Based on empirical data collected from 198 Korean firms in the knowledge-intensive business service sector, four major clusters composed of different service innovation dimensions are identified. These four clusters can be interpreted as specific service innovation patterns, including "technology based high customer interaction," "high technology based high service delivery," "service delivery and high customer interaction-integrated," and "strongly balanced" innovators. High firm performance does not depend on the individual service innovation dimension but on the specific configurations of such service dimensions. Customer interaction also has an important role in achieving innovation success and improving firm performance, while technology has a key role in enhancing firm performance. This study sheds new light on service innovation research by developing a new typology of service innovation, identifying four major clusters as service innovation patterns, and exploring the relationship between service innovation patterns and firm performance.

The results of analyzing the cognition of CPR by college students who major in public health or not order to enhance the educational efficiency of first aid ability and its expansion are as follows. 1. In case of students majoring in public health, the students who have the knowledge of term 'CPR' are 95.3% of total 300 students and 62.6% of the students who don't major in public health know it. In the item test of examining the degree of theoretical knowledge of CPR, the cases who know all 12 items are 5.2% and 1.6% respectively in cases who major in public health and don't major in it and it is judged that the extension of educational opportunity for them should be urgent. 2. The students who have experienced the practice of CPR are 20.6% in case who major in public health and 7.4% in other case. Therefore it seems to desirable that indirect field experience should be obtained by strengthening practice centered education. 3. The order of practice to examine the CPR ability is asked and the students who show very good remark are just 21~22% in both cases and they conducted very ineffective CPR and it is examined that they did first aid which may a serious damage to patients. Then the cases who recovered pulse and respiration after CPR were very low as 28.8% in the students who major in public health and 35.7% in others. It is therefore considered that the exact education of conducting the maintenance of respiratory trace, artificial respiration and CPR is necessary. 4. The cases who had the education of CPR were 51% in the students who major in public health and 39.4% in others, who had little opportunities to have CPR and 92.5~93.2% in both groups fee the necessity of continuous education and it is very encouraging to extend the education of CPR. 5. The education of CPR is mainly done at school (70.3~79.4%) and from teachers (52.7~55.4%) and 71.2% of the students majoring in public health responded that it is good for them to have education of CPR at school and lecture by first-aider and 58.9% of others did it. The cases who ask for lecture by the Professors of Dept. of First-Aid are 11.8 in students majoring in public health and 13.1% in others and it is judged that lecture by them having the theoretical foundation and first-aider with practical ability will be desirable. 6. On teaching methods, 57.5% of the cases majoring in public health and 63.3% of others ask for practice and 20% of both groups need theory centered teaching. 7. On lecture fee, 83% of the cases majoring in public health and 83.3% of others consider it should be free and 8~11.8% who are to pay for 10,000 won and it is judged that it should be opened and operated as liberal arts by college in the dimension of lifelong education. 8. On the objects of education, 83% of cases majoring in public health and 66.6% of others consider it should be conducted in people of all ages and both sexes and it is known that everyone recognizes the necessity of popularizing the education of first-aid.

This study is to consider economic, political, socio-cultural and environmental characteristics of the new urbanization process and its spatial structures and urban policy of Seoul in the 1990s. Some experimental findings which have been identified throughout this study can be summarized as follows. First of all, Seoul, the largest city in S.Korea has experienced a restructuring process of economy, which has been promoted by the development of producer services as well as knowledge- based or high tech industries. Secondly, the autonomy of Seoul has increased after the introduction of local self-government, with relatively higher self-management of local finance than other cities, strengthening the tendency of enterpreneurialism, empowering civil movements, and increasing the political participation of women. Thirdly, in the socio-cultural aspect, the material wants to gain a certain identity through consumption, using urban environments culturally, varying consuming attitudes and ways of leisure times in relation with the rapid development of transportation and information communication. Fourthly, in the environmental aspect, Seoul has tried to introduce the concept of sustainable development in terms of increasing wants on the quality of life, and to develop a pro-environmental eco-city with environmental rehabilitation, constructing green space and eco-park. Finally, in the spatial dimension, Seoul has shown a structuration of multi-centers, with highly spectacular urban landscapes and seemingly authentic urban planning. These results make us confirm that Seoul has been in the process of new urbanization which can be distinguished from the previous one.

As a large amount of data is produced in each industry, a number of time series pattern prediction studies are being conducted to make quick business decisions. However, there is a limit to predicting specific patterns in nonlinear time series data due to the uncertainty inherent in the data, and there are difficulties in making strategic decisions in corporate management. In addition, in recent decades, various studies have been conducted on data such as demand/supply and financial markets that are suitable for industrial purposes to predict time series data of irregular random walk models, but predict specific rules and achieve sustainable corporate objectives There are difficulties. In this study, the prediction results were compared and analyzed using the Chaos analysis method for roulette data and financial market data, and meaningful results were derived. And, this study confirmed that chaos analysis is useful for finding a new method in analyzing time series data. By comparing and analyzing the characteristics of roulette games with the time series of Korean stock index future, it was derived that predictive power can be improved if the trend is confirmed, and it is meaningful in determining whether nonlinear time series data with high uncertainty have a specific pattern.

Although many studies have stressed the importance of technology in service innovation, the roles of technology in service innovation are at the center of debates in the service innovation literature. One major research stream regards technology as a trigger for other innovation based on resource advantage theory. Conversely, another major stream considers it as an enabler of other innovations based on complementary theory. The contradictory situation induces the necessity to better understand the role of technology in service innovation. Therefore, this study aims to identify the role of technology in service innovation. This study investigates the role of technology in service innovation based on a service innovation orientation framework. Four service innovation orientations (i.e., service creation, service delivery, customer interaction, and technology) are identified on the basis of Den Hertog's 4D model. This study proposes a research model that examines the indirect effect of technology orientation on innovation performance through the service creation and service delivery orientations, and the effect of technology orientation on firm performance as a moderator between customer interaction orientation and firm performance. Based on empirical data from 193 knowledge-intensive business service firms in Korea, we explain the role of technology in service innovation. The results indicate that technology orientation influences both service creation and service delivery orientations as an antecedent but customer interaction orientation as an enabler. The three service innovation orientations, which are directly and indirectly influenced by technology orientation, positively affect firm performance. The findings also show that the role of technology is different depending on the type of service innovation orientation in this study.

In the era of knowledge-based society and glocalization the new role and mission of universities is of increasing concern to us. Studies of the successful universities suggest that there are many ways for the future development of universities, for example high qualification, specialization, and internationalization of universities etc. In this context we can also focus particularly on the regionalization of universities in terms of the university as a regional builder. This paper aims to identify the interactions between universities and regions and to explain their's contributions to the regional developments. The result of analysis shows that the university-region interaction is a win-win strategy both for university and for region in the rapid changing social-economic, administrative and educational environments, and more systematic and stepwise approaches are required to ensure a mutually beneficial collaboration.

We develop the Spatio-Temporal Graph to imbue the historical context to the situations in a virtual world, and an ontology to enable a structural description of their elements such as the objects, relationships, and activities. In the time dimension the graph models all the temporal phases of the future besides the past and present in a comprehensive manner, and all the spatial aspects in an intuitive but efficient fashion. The overall architecture composing the Physical Layer, Logical Layer and Conceptual Layer which are integrated according to their interrelations allows events occurring in their corresponding worlds to be simulated in historical context. The S-T Graph could be used both to simulate the situations in the virtual world and to realize the knowledge systems of the virtual inhabitants to be used in judging and evaluating those situations. By adding temporal changes to the multi-layered architecture of our virtual world, this model lays a foundation for maximizing the diversity of situations in the simulation of a virtual world.

In the Janggun mine, stannite occurs as anhedral grains, up to 500 micrometer in long dimension, closely associated with sphalerite, chalcopyrite, arsenopyrite, pyrrhotite, galena and rhodochrosite in the periphery of the South ore body. In reflected light, stannite is grayish yellow green in color and exhibits moderate bireflectance and strong anisotropism without any intenal reflections. Reflection; Rmax. =29.0, Rmin. =27.8 percent at a wavelength of 560nm, and VHN; 219~244kg/mm at a 50g load. The chemical composition on the average from 35 spot analyses by electron microprobe is, Cu 28.0, Fe 12.7, Zn 2.9, Mn 0.2, Sn 25.8, S 30.3, sum 99.9 (all in weight percent); the corresponding chemical formula as calculated on the basis of total atoms=8 is, Cu 1.88 Fe 0.97 Zn 0.19 Mn 0.02 Sn 0.93 S 4.01, which fulfills approximately the ideal formula of $Cu_2FeSnS_4$. The strongest reflections on the X-ray diffraction patterns are; $3.10{\AA}$ (10) (112), $2.72{\AA}$ (5) (020, 004), $1.922{\AA}$ (5) (024), $1.642{\AA}$ (3) (132), $1.244{\AA}$ (3) (143, 136, 235), $1.111{\AA}$(3) (244), $0.958{\AA}$ (1) (048, 422), the patterns are identical with those of literature. From the textural evidence of the microscopic observation, the mineral is considered to have been formed at the middle stage of hydrothermal lead-zinc-silver mineralization.

Knowledge of dynamic characteristics of structural elements often can make difference between success and failure in the design of structure due to resonance effect. In this paper an analytical model of a cantilever beam having midpoint load is considered for structural optimization. This involves creating the geometry which allows parametric study of all design variables. For that purpose optimization of cantilever beam is elaborated in order to find the optimum geometry which minimizes its volume eventually for minimum weight using ANSYS. But such geometry could be obtained by different combinations of width and height, so that it may have the same cross sectional area yet different dynamic behavior. So for optimum safe design, besides minimum volume it should have minimum vibration as well. In order to predict vibration different dynamic analyses are performed simultaneously to solve the eigenvalues problem assuming no damping initially through MATLAB simulations using state space form for modal analysis, which identifies the resonant frequencies and mode shapes belonging to the lowest three modes of vibration. And next by introducing damping effects tip displacement, bending stress and the vertical reaction force at the fixed end is evaluated under some dynamic load of varying frequency, and finally it is discussed how resonance can be avoided for particular design. Investigation of results clearly shows that only structural analysis is not enough to predict the optimum values of dimension for safe design. Potentially this technique will meet maintenance and cost goals of many organizations particularly for the application where dynamic loading is invertible and helps a lot ensuring that the proposed design will be safe for both static and dynamic conditions.

The purposes of this study are to examine older consumers' seeking benefits and purchase intentions for functional materials and their attitudes towards such materials and investigate the differences between purchasers and non-purchasers of functional materials in their seeking benefits for functional materials and their emphasis on self development and pursuit of fashion. In doing so, this study samples the older adult population living in Seoul, Busan, and Gyeonggi Province and analyzes 267 questionnaire responses obtained from the sampled older consumers. The main findings from the analysis are as follows: First, the older consumers' seeking benefits for functional materials were represented by three different dimensions: reliability, brands/fashion, and others-oriented pursuit. Second, the influence on the dimension of reliability was more significant in the order of knowledge on functional materials, pursuit of fashion, and emphasis on self-development the interest in garments and the pursuit of fashion were found to have significant influence on the dimensions of brands/fashion and others-oriented pursuit. Third, the respondents' attitudes towards functional materials showed significant correlations with the dimensions of reliability and others-oriented pursuit, while their purchase intentions for functional materials were significantly influenced by the dimensions of reliability and brands/fashion. Finally, when the differences in the respondents' seeking benefits for functional materials and their pursuit of fashion and emphasis on self-development were investigated according to whether or not they had ever purchased clothes made from any functional material, the group of purchasers showed a higher mean value than the non-purchaser group.
