This study aims to derive implications on current problems in the nursing manpower management in Korea through the comparison with the nursing workforce and employmentrent in the United States and Japan. There are various issues in nursing policy, such as nursing shortage, quality of the nursing service, and the increased cost of management due to the high turnover rate of nursing staffs and it is urgent to seek various policy measures to resolve this. Although nursing shortage is a commom problem in the world, the U.S. and Japan were higher rate of employment than Korea in nursing staffs, which implicates the importance of the legislation of mandatory minimum staffing ratios, the establishment of policies such as the fees and charge policy and the nursing work environments. For quality nursing care and patient safety through the stable workforce of qualified nursing staffs, administrative mechanisms that support adequate nurse staffing and promote positive work conditions are needed, for which the improvement of legal system is required.

China's reading campaign has started as part of youth education since 1993 and also has been conducted as government-level 'national reading activities' since 2006. This study was conducted to investigate and analyzed China's reading campaign as part of overseas case study of reading campaign, based on literature studies and internet survey method as well as meta study. As regard reading status, Chinese people's reasons to read or not to read books plus reading rate and reading amount were reviewed and the background, operation style and major activities of 'national reading activities' were investigated. The characteristics and problems of China's reading campaign were reviewed and 1) national level reading campaign, 2) intensive reading campaign through common subject and 3) youth reading education for self-education and character development were put forth for the betterment of reading campaign in Korea.

The goal of this study is an exploratory statistical analysis of the university and college library statistics in the Academic Information Statistics System(rinfo.kr) governed of Korean Education and Research Information Service(KERIS) with performance measures based on sustainability. For the goal, we adopt a preprocessing method to develop change-rate variables by considering preceding predictive elements and succeeding performance elements, and to control external factors, such as size and socioeconomic factors. Then we execute a series of factor analyses and multiple linear regression analyses. 13 factors are extracted by the factor analyses and some sets of significant variables affecting the performance measures are identified through the regression analyses. Based on the results, we discuss the problem of out-lier and low correlation between variables. A suggestion for developing new variables is also discussed based on low effect sizes of the developed regression models. We hope that this study contributes to diffuse discussions on statistics system, evaluation, and further library management based on sustainability.

To train convergence experts ICT infrastructure must be learned IoT use capabilities of things. In this paper, targeted to students that are majoring in computer science, and for the design of the curriculum and the educational model that handles education of operation in general for training IoT-related education for five months to experts of convergence training describe the contents. Course is the basic ability of the process, core competence course, is divided into real-life capability process and on-site training course, was constructed in a total of 10 stages of the process details. Curriculum, it was designed to learn sensing technology, network technology, security, and content production technology. This educational model is utilized for job creation human resource training project of 2015 Ministry of Employment and Labor, it demonstrated the utility to contribute in order to achieve a high completion and the employment rate. Applicable to future university education plans to expand the curriculum, including courses that complement the Java.

Road signs are guide facilities for road users, and the Ministry of Land, Infrastructure and Transport has established and operated a system to enhance the convenience of managing these road signs. The role of road signs will decrease in the future autonomous driving, but they will continue to be needed. For the accurate mechanical recognition of texts on road signs, automatic road sign recognition equipment has been developed and it has applied image-based text recognition technology. Yet there are many cases of misrecognition due to irregular specifications and external environmental factors such as manual manufacturing, illumination, light reflection, and rainfall. The purpose of this study is to derive location-based destination names for finding misrecognition errors that cannot be overcome by image analysis, and to improve the automatic recognition of road signs destination names by using Levenshtein similarity verification method based on phoneme separation.

The expansion work that is wasted through the irreversible expansion through the PC valve of decompression process of the natural gas governor station can be recovered by replacing the process by an isentropic expansion. The energy and exergy analyses for the two decompression process models of power producing and current decompression process model are presented. Analysis results showed that the exergy by gas supply is 56.29%, the exergy by producing power is 32.12 % in case of preheating system and 22.52% in case of non-preheating system. The dead exergy at the PCV is generated much more network. As these results, the usefulness of exergy analysis is verified.

According to a statistical survey, despite the continuous improvement of the economic level, the participation rate of donations is decreasing. As a cause of this phenomenon, the problem of reliability of donation organizations is a big part. In order to increase viewers' intention to donate, this study developed a donation campaign linked data service that shows information that can increase the credibility of donation organizations and storytelling of donation recipients. Specifically, a user scenario of a data service that is properly operated in conjunction with a donation campaign that is broadcast shortly was defined, and a user interface was designed by reflecting the characteristics of the TV platform. In addition, a prototype based on the DVB-MHP standard was developed to analyze the effect of the data service utilization on viewers' intention to donate.

Precipitation is an important component for hydrological and water control study. In general, AWS data provides more accurate but low dense information for precipitation while radar data gives less accurate but high dense information. The objective of this study is to construct adjusted precipitation field based on hierarchical spatial model combining radar data and AWS data. Here, we consider a Bayesian hierarchical model with spatial structure for hourly accumulated precipitation. In addition, we also consider a redistribution of hourly precipitation to 2.5 minute precipitation. Through real data analysis, it has been shown that the proposed approach provides more reasonable precipitation field.

In July 2010, The Korean government announced a plan to implement smart work centers to resolve low birth rate, low productivity and social costs of the urban traffic jams. The Plan calls for up to 30 percent of the working population to be working under the smart work system by 2015. This empirical study was conducted to find factors affecting the Smart Work Center use. Based on the IS Success Model, 'operation Infra Quality' and 'User Satisfaction' have positive impact on the Smart Work Center use. 'System Infra Quality' and 'IT Infra Quality' have positive impact on the 'User Satisfaction'. Consequently 'System Infra Quality' and 'IT Infra Quality' have positive impact on the Smart Work Center use indirectly.
