We introduce various methods to investigate the relations between innovation of technology and social changes by analyzing more than 4 millions of patents registered at United States Patent and Trademark Office(USPTO) from year 1985 to 2015. First, we review the history of patent law and its relation with the quantitative changes of registered patents. Second, we investigate the differences of technical innovations of several countries by use of cluster analysis based on the numbers of registered patents at several technical sectors. Third, we introduce the PageRank algorithm to define important nodes in network type data and apply the PageRank algorithm to find important technical sectors based on citation information between registered patents. Finally, we explain how to use the canonical correlation analysis to study relationship between technical innovation and social changes.

Purpose: The purpose of this study was to identify the relationship between sense of coherence and quality of life in the freshman nursing students. Method: The subjects of this study were 377 freshmen of nursing colleges. Data were collected through structured questionnaires of sense of coherence and quality of life. Data analysis was done using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and canonical correlation analysis. Result: There was static correlation between sense of coherence and quality of life in the freshman nursing students. And high correlation with quality of life were meaningfulness in sense of coherence and psychological domain in quality of life. Conclusion: These results were shown very important to improve meaningfulness in sense of coherence and psychological domain in quality of life to raise the quality of life in the freshman nursing students. Therefore, in order to improve the quality of life, it is necessary to develop a nursing intervention program that focus on stress, and psychological health.

This study investigated relationships between the importance and satisfaction of rice-based menu selection attributes at family restaurants. For data collection, a total of 250 copies of questionnaires were distributed to 4-year college students who had an experience of a rice-based menu at casual dining restaurants, and finally 221 surveys (88.4%) among them were analyzed by using SPSS Win ver. 11.5. Twenty selection attributes were used to test the level of importance and satisfaction for rice-based menu. The factor analysis identified six dimensions of the importance of rice-based menu selection attributes; variety of items, menu information, recommendation & atmosphere, food quality, preferred menu, and price. Also, five dimensions of satisfaction were identified as nutrition & taste, menu information, preferred menu & atmosphere, variety of items, and cooking. Canonical correlation analysis revealed that preferred menu factor of importance was highly correlated with preferred menu and restaurant atmosphere factor of satisfaction of rice-based menu selection. The managerial implications of these results for rice-base menu selection attributes are as follows: There seems to be a need to develop a variety of rice-based menus, because rice-based menus tend to be considered as an additional menu, not a main course. Aggressive marketing and communication strategies are necessary to position rice-based menu as a main course for college students and as a major maket segment to family restaurants.

The purpose of this study was to explain the performance pattern of health education and related factors in elementary school. The data were collected from school nurses who have been working elementary school. Sample of 77 were analyzed by percent distribution, ${\chi}^2$-test, discriminant analysis. The performance rates of health education was 74%, Only 19% of total carried out health education of 6 hours per week. Important variables that was showed significant association with health education level were as follows: Perception of importance about health education among personal characteristics of school nurses and size of school c1ass, cooperation level of school administrator, operation method of school health clinic, the difficulty of school health clinic among school organization characteristics. The canonical correlation between the health education (yes or no) and important independent variables was 0.52. Among them, operation method of school health clinic. perceiveness of health education, size of school class represented the significant contribution (canonical coefficient: 0.66, 0.54, 0.52) to school health education. These findings suggest that structure and management variables of school organization are more important than personal variables of school nurses related to activation of school health education. Therefore, it is expected that the quantity and quality improvement of school health education be able to accomplish through the systematic support of school organization and government demension.

The purpose of this study was to examine the relationships between ego- resilience and stress coping styles of adolescents. The study also tried to identify differences on stress coping styles based on the level of ego- resilience of adolescents. Ego-resilience showed positive correlations with problem-focused and social support seeking coping styles and a negative correlation with an emotion-focused coping style. Canonical Correlation analysis revealed that self-confidence among four sub-domains of ego-resilience made the most outstanding contributions in predicting stress coping styles of adolescents. The problem-focused coping style had the highest correlation with ego-resilience among the four coping styles. The group of adolescents who had a higher level of ego-resilience reported more problem-focused and social support-seeking coping styles in stressful situations. The results of this study suggested that development of ego-resilience of adolescents who were in the midst of transitions and adjustment problems was important for effective coping strategies.

This study was conducted from March to August 1997 to decide the size of plant community in fragmentary habitats. The thirty one sites and one hundred and eighteen plots were plotted in the areas including Yangpyong, Yoju, Pyongtaek and Ansong in Kyonggi-do, Chomchon and Sangju in Kyongsangbuk-do, Nonsan in Chungchongnam-do and Iksan in Chollapuk-do. The area and number of woody species by correlation analysis were recorded as the highest value as 0.716. In order to apply the theory of island biogeography to the fragmented habitats in Korea, the four variables were calculated by regression model. The four variables such as number of woody species, number of woody individuals, number of herbaceous species and number of herbaceous individuals were recorded as significant with area at the level of 0.05 and R square was 0.71. The one function was selected between number of species and number of individuals from the canonical correlation analysis, and the function square was 0.8876. Both canonical function and squared canonical correlation showed significant at the level of 0.01. The number of species and individuals were not increased from the condition that was the size of plant community of 400$m^2$, 30 for number of species and 4,000 for number of individuals. This results of this study can be widely used as a basic information for the conservation management, especially the fragmented ecosystems or the biotop creation in the landscaping.

It is necessary to examine relationship between spatial patterns of forest types and characteristics of forest fires for efficient management of fire and forest. By the ecoregions of South Korea, we computed landscape indices for whole types of forests(landscape level) and pine forests(class level), and analyzed characteristics of forest fires using statistics of forest fires from 1991 to 2006. We performed canonical correlation analysis to model the relationship between the landscape indices and the statistics of forest fires. At landscape level, forest patches were larger and more complex in the ecoregions which had higher percentage of forest area. At class level, pine forest patches were more complex and closer to neighbor patches in the coastal ecoregions. The ecoregions including metropolitan areas and cities had more frequent fire occurrences per 1,000ha, while mountainous coastal ecoregions had more burned areas and faster spread of fire growth rate. The canonical correlation between the landscape indices for pine forests and the statistics of forest fires was statistically significant at the 0.05 level and explained more than 70% of the variation in fire variables. The results showed that combustion time per fire was longer in the ecoregions which had larger and more aggregated pine forest patches.

Purpose: This study is to determine the patterns of relationship between organizational socialization (OS) and organizational citizenship behavior (OCB) among nurses working in a general hospital setting by examining whether organizational adaptation through OS leads to positive behavioral changes, which may be helpful to improve organizational performances. Methods: The data were collected from 494 nurses in five general hospitals using a structured questionnaire, and they were analyzed by conducting canonical correlation analysis using SPSS 12.0. Results: The analysis of the relationship patterns between OS and OCB revealed that two significant canonical correlations between the two groups of nurses with less than 5 years of working experience (LT) vs. more than 5 years of experience (MT), respectively. Thus, the complicated correlations between OS and OCB were identified. The variables that contributed to each canonical function most were 'politics', 'organizational goals and values' in the LT group, and 'organizational goals and values' and 'language' in the MT group. The notable point in the relation between OS and OCB in our study was negative contribution of 'sportsmanship' among the OCB variables in the MT group. This is thought to be the negative effect of OS. Conclusion: More effective workforce management could be achieved by adopting a differentiated approach according to work experience. To develop a better program to enhance OS, more careful attention to OCB of experienced nurses should be paid to minimize a negative effect on organization while rewarding individuals or departments for a positive organizational behavior.

The purpose of this study was to examine the relationship between fathers' child-rearing behavior and the competencies of their children and to suggest ways in which fathers can exert a positive influence on their children. The subjects were the fathers and mothers of 649 six- to seven-year-old children attending schools located in T city. Data was analyzed by frequency, percentile, mean, standard deviation, correlation analysis and canonical correlation analysis. Results showed that "limit setting" was the most frequently used child rearing behavior by fathers. On the other hand fathers' "reasoning guidance" was correlated with children's personalities and intellectual competencies.
