Purpose: This study was conducted to examine the differences in organizational commitment, nursing organization culture, and job satisfaction of Korean nurses employed in Korea and the United States, and to determine how these variables were associated with selected study characteristics. Methods: An exploratory cross-sectional study was performed with a convenience sample of 357 nurses from Korea and the U.S. Data were collected by using a web site survey and self-reported questionnaire. Descriptive statistics, t-tests, ANOVA, and Pearson's correlation coefficients were used for data analysis. Results: In comparison to Korean American nurses (KAN), Korean nurses (KN) were younger, single, worked more time, took a charge role or higher, and had less turnover experience. After controlling for age and marital status, nursing organization culture and job satisfaction of KN were significantly lower than those of KAN, respectively (F= -26.02, p<.001; F= -4.87, p=.028). Significant relationships among selected socio-demo-health and work-related characteristics and the three variables were higher for KN. Conclusion: Higher organizational commitment and nursing organization culture from all Korean nurses were related their perceived high level of job satisfaction. Recommendations for further study include exploring a larger sample size of a variety of different types of nursing organizations and staff as well.

Data mining is the method to find useful information for large amounts of data in database. It is used to find hidden knowledge by massive data, unexpectedly pattern, relation to new rule. We need a data mining tool to explore a lot of information. There are many data mining tools or solutions; E-Miner, Clementine, WEKA, and R. Almost of them are were focused on diversity and general purpose, and they are not useful for laymen. In this paper we design and implement a web-based data mining tool using PHP and WEKA. This system is easy to interpret results and so general users are able to handle. We implement Apriori algorithm of association rule, K-means algorithm of cluster analysis, and J48 algorithm of decision tree.

Realtime search words of typical portal sites appear every few seconds in descending order by search frequency in order to show issues increasing rapidly in interest. However, the characteristics of realtime search words reordering within too short a time cause problems that they go over the key issues of the day. This paper proposes a method for deriving a key issue through association analysis of realtime search words. The proposed method first makes scores of realtime search words depending on the ranking and the relative interest, and derives the top 10 search words through descriptive statistics for groups. Then, it extracts association rules depending on 'support' and 'confidence', and chooses the key issue based on the results as a graph visualizing them. The results of experiments show that the key issue through association rules is more meaningful than the first realtime search word.

Objectives: This study analyzed the relationship between BMI (body mass index), perceived health status, and oral health behaviors of schoolgirls. Methods: This study utilized data from the 13th (2017) Korea Youth Risk Behavior Web-Based Survey. A total of 29,337 schoolgirls were analyzed. Statistical analysis was performed using PASW Statistics 21.0 (SPSS Inc., Chicago, IL, USA). Results: Compared to the obese group, the rate of being recognized as healthy was 1.882 times higher in the normal-weight group and 1.623 times in the underweight group. The rate of using supplementary oral hygiene devices was 1.383 times higher in the underweight group and 1.091 times in the normal-weight group than in the obese group. Compared to the obese group, the experience rate of the sealant was 1.407 times in the underweight group. Compared to the obese group, the scaling experience rate was 1.282 times higher for the underweight group and 1.205 times for the normal-weight group. Conclusions: These results suggest that individual health behaviors are interrelated. There is a need for an integrated approach in the planning and implementation of future health promotion strategies, and it would be useful to design a program that considers health characteristics such as BMI.

Based on the 'Government 3.0', the government opens the public data and encourages the active use in the private sector. Recently, the spatial and statistical information that is one of the public data is being widely used in the various web business as a high value-added information. In this study, we propose an architecture of high-availability, high-reliability and high-performance open platform which can provide a variety of services such as searching, analysis, data mining, and thematic mapping. In particular, we present two different system architectures for the government and the public services, by reflecting the importance of the information security and the respective utilization in the private and public sectors. We also compared a variety of server architecture configurations such as a clustered server configuration, a cloud-based virtual server configuration, and a CDN server configuration, in order to design a cost- and performance-effective spatial-statistical information open platform.

The purpose of this study is to analyze science fields and content elements of the science reports in a web portal site of Republic of Korea in view of scientific literacy. The main results of the analysis on the 679 reports sampled in a year are as follows. First, 506 reports in 46 fields were identified. Reports about technology and earth science occupies 16% respectively, and life science occupies 13%, medical science 4%, chemistry, company, others 3% and physics 1%. Almost reports show technology as associate field. Second, the frequency rate of reports including scientific literacy content elements is 52%. Reports related to 'physics' and 'chemistry' as dominant fields show relatively high rate in scientific literacy elements. The element, 'social context' is included in about 96% of the reports. Both 'data and statistics' and 'application' show relatively low rate and large gaps according to dominant fields. A few concluding remarks and proposals follow from these results. First, as almost science reports show the nature of integrated science, scientific literacy acquisition through science reports in internet requires the integrated scientific view. Especially most science reports includes the contents related to technology or medical science, so the point of view in the science-technological literacy is required. Second, the scientific literacy content elements in reports show various rates according to dominant fields. Therefore, science reports need to complement the deficient content elements to carry out the role of science reports as scientific literacy sources.
