The object of this study is to compare the cognitive differences between teenagers who are operating the internet shopping mall and those who are not operating to analyze the effect of the enterprise experience on the career maturity of teenager. And we are to present the operation methods of teenager entrepreneurship education at school by identifying the difficulties of teenager internet shopping malls and investigating demands of teenagers for the entrepreneurship education. The results of this study are as following. First, the internet shopping malls established by teenagers were mostly operated with small scale and capital dealt with clothing and fashion accessories. It is difficult for most of teenagers to inform the shopping malls and understand the flow of fashion and demands of consumers. They acquired the informations on enterprise using internet or acquaintances. This is because there are no professional teenager entrepreneurship education. And they chose the confidence and spirit of challenge which are mostly needed for success of the internet shopping malls. Therefore, they can acquire the confidence and spirit of challenge by effective entrepreneurship education on resource management, team management, business plan and marketing. Second, teenagers who are operating the internet shopping malls got higher scores on career maturity and degree of need in the entrepreneurship education than those who are not. Thus the expansion of the systemed and diversified entrepreneurship education at school is needed to increase business practice and entrepreneurship. Third, most teenagers wanted the entrepreneurship education at school. They preferred external lectures who can teach them with professional experiences and practical knowledges using discretional activity classes or club activity classes. Dividend classes of creative experience activities including career, voluntary and club activities are increased in 2009 revised education curriculum. Using these classes, it requires to operate the entrepreneurship education which make students decide their career themselves through concrete education and experience. Consequently, the expansion of the systemed and diversified teenager entrepreneurship education at school is needed using development of practical entrepreneurship education program, professional teacher training and revitalization of entrepreneurship club activities.

As big data are one of main issues in the recent days, the interests on their technologies are also increasing. Among several technological bases, this study focuses on data visualization and R based on open source. In general, the term of data visualization can be summarized as the web technologies for constructing, manipulating and displaying various types of graphic objects in the interactive mode. R is an operating environment or a language for statistical data analysis from basic to advanced level. In this study, a web application with these technological aspects and components is newly implemented and exemplified with data visualization for geo-based open data provided by public organizations or government agencies. This application model does not need users' data building or proprietary software installation. Futhermore it is designed for users in the geo-spatial application field with less experiences and little knowledges about R. The results of data visualization by this application can support decision making process of web users accessible to this service. It is expected that the more practical and various applications with R-based geo-statistical analysis functions and complex operations linked to big data contribute to expanding the scope and the range of the geo-spatial application.

Background: Early extubation after cardiovascular surgery has some clinical advantages, including reduced hospitalization costs. Herein, we review the results of ultra-fast-track (UFT) extubation, which refers to extubation performed on the operating table just after the operation, or within 1-2 hours after surgery, in patients with congenital cardiac disease. Methods: We performed UFT extubation in patients (n=72) with a relatively simple congenital cardiac defect or who underwent a simple operation starting in September 2016. To evaluate the feasibility and effectiveness of our recently introduced UFT extubation strategy, we retrospectively reviewed 195 patients who underwent similar operations for similar diseases from September 2015 to September 2017, including the 1-year periods immediately before and after the introduction of the UFT extubation protocol. Propensity scores were used to assess the effects of UFT extubation on length of stay (LOS) in the intensive care unit (ICU), hospital LOS, and medical costs. Results: After propensity-score matching using logistic regression analysis, 47 patients were matched in each group. The mean ICU LOS ($16.3{\pm}28.6$ [UFT] vs. $28.0{\pm}16.8$ [non-UFT] hours, p=0.018) was significantly shorter in the UFT group. The total medical costs ($182.6{\pm}3.5$ [UFT] vs. $187.1{\pm}55.6$ [non-UFT] ${\times}100,000$ Korean won [KRW], p=0.639) and hospital stay expenses ($48.3{\pm}13.6$ [UFT] vs. $54.8{\pm}29.0$ [non-UFT] ${\times}100,000KRW$, p=0.164) did not significantly differ between the groups. Conclusion: UFT extubation decreased the ICU LOS and mechanical ventilation time, but was not associated with postoperative hospital LOS or medical expenses in patients with simple congenital cardiac disease.

The purpose of this study are 1. Evaluate the degree of knowledge of Vaginal Birth After Cesarean(VBAC) of Korean nurses. 2. To gather and develop educational material for VBAC. The sample was surveyed Korean Nurses knowledge about VBAC, from November 1998 through March 1999. For the data analysis, the SPSS computer program percentage and frequency were used for descriptive statistics. The x2 and the t-test were used to compare the results of the two sample groups. Open questions asked in the survey were sorted out by content, then displayed in chart form. For the education material, the Internet was the main source of information. Information on the Internet was provided by professional doctors and prenatal educational nurses. The results of the survey are as follows: 1. Out of 97 Nurses 15.3% answered that cesarean deliveries do not need to be performed after previous cesarean sections : however. 46.4% answered that cesarean sections must be performed after previous cesarean sections. 2. Of the nurses surveyed 14% had no knowledge or had never heard of VBAC. 3 Nurses did not have questions from patients concerning VBAC was 34.7%. This led to the conclusion that patients either do not have knowledge about VBAC or patients have no interest in the trial of labor. 4, Nurses indicated that their information about VBAC originated from other people's experiences (31%), Nursing School (25%), Media information (9%), and through literature review (6%). This data led to the conclusion that the knowledge about VBAC may not be extensive enough to counsel and guide patients who are willing to endure the trial of labor. 5. Nurses preferred hospital education programs to develop their knowledge concerning VBAC. Based upon survey, the conclusion was made that General Nurses and Maternity Nurses did not have knowledge about VBAC success rates and the possibility of a trial of labor. In order for nurses to help patients make decisions concerning VBAC, nurses have to gam more knowledge through hospital educational programs. Further more, the study suggests that through hospital educational programs, the possibility and importance of VBAC must be emphasized to nurses who work in maternity areas. Second, through prenatal educational programs, the possibility and importance of VBAC must be explained and emphasized to patients who had previous cesarean sections. Third, the clinical pathways of VBAC need to be developed. Fourth, each hospital needs to develop multi-disciplinary teams, consis-ting of obstetricians, risk management/quality management, staff registered nurses, and the director for perinatal services. This team can review cesarean section rates and help to increase the practice of VBAC.

The usefulness of processing and analysis systems of GIS-based agricultural climate data is affected by the reliability and availability of computing infrastructures such as cloud, on-premises, and hybrid. Cloud technology has grown in popularity. However, various reference cases accumulated over the years of operational experiences point out important features that make on-premises technology compatible with cloud technology. Both cloud and on-premises technologies have their advantages and disadvantages in terms of operational time and cost, reliability, and security depending on cases of applications. In this study, we have described characteristics of four general computing platforms including cloud, on-premises with hardware-level virtualization, on-premises with operating system-level virtualization and hybrid environments, and compared them in terms of advantages and disadvantages when a huge amount of GIS-based agricultural climate data were stored and processed to provide public services of agro-meteorological and climate information at high spatial and temporal resolutions. It was found that migrating high-resolution agricultural climate data to public cloud would not be reasonable due to high cost for storing a large amount data that may be of no use in the future. Therefore, we recommended hybrid systems that the on-premises and the cloud environments are combined for data storage and backup systems that incur a major cost, and data analysis, processing and presentation that need operational flexibility, respectively.
The purpose of this study was to draw out success factors of port operation for New International Passenger Terminal(NIPT) in Incheon Port using the fuzzy method. In this study, the success factors of port operation were firstly selected by literature review and finally adopted them by in-depth interview with experts who had working experiences over 15 years in the field of Korea-China Carferry shipping business and stevedoring business. Success factors of port operation of the NIPT have been classified into four principal factors such as 'land's use side', 'productivity side', 'cost side' and 'services side', and the comparative analysis was conducted among success factors of port operation. According to the results of analysis, in terms of "land's use side", securing CY space of full-empty containers(0.857) was the most important factor. Among detailed factors of "productivity side", building terminal automation system(0.806) was significantly needed. In the factors of "cost side" and "service side", land rental costs(0.861) and schedule management of berth operation(0.798) were selected as the most important factors. Consequently, new international passenger terminal has implications that the main port operations should focus on reasonable rents calculation, ensuring proper space of CY, and building automation system of terminal, There is a need to proceed to conduct a comparative study of the same operating mode of an international passenger terminal.
Due to recent rapid deployment of Internet streaming service and digital broadcasting service, the issue of how to efficiently support streaming workload in so called "Internet Home Appliance" receives prime interests from industry as well as academia. The underlying dilemma is that it may not be feasible to put cutting edge CPU, boards, disks and other peripherals into that type of device. The primary reason is its cost. Usually, Internet Home Appliances has its dedicated usage, e.g. Internet Radio, and thus it does not require high-end CPU nor high-end Va subsystem. The same reasoning applies to I/O subsystem. In Internet Home Appliances dedicated to handle compressed moving picture, it is not equipped with high end SCSI disk with fast rotational speed. Thus, it is mandatory to devise elaborate software algorithm to exploit the available hardware resources and maximize the efficiency of the system. This paper presents our experiences in the design and implementation of a new multimedia file system which can efficiently deliver the required disk bandwidth for a periodic I/O workload. We have implemented the file system on the Linux operating system, and examined itsperformance under streaming I/O workload. The results of the study show that the proposed file system exhibits superior performance than the Linux Ext2 file system under streaming I/O workload. The result of this work not only contribute to advance the state f art file system technology for multimedia streaming but also put forth the software which is readily available and can be deployed. deployed.

This note provides technical guide on three issues associated with establishing and automatically running regional ocean forecasting systems: (1) a strategy for continuous production of hourly-interval three-day ocean forecast data, (2) the daily download of ocean and atmospheric forecasting data (i.e., HYCOM and NOAA/NCEP GFS data), which are provided by outside institutions and used as initial condition, surface forcing, and boundary data for regional ocean models, and (3) error notifications to numerical model managers through the Short Message Service (SMS). Guidance on dealing with these three issues is illustrated via solutions implemented by the Korea Hydrographic and Oceanographic Agency, since in embarking on this project we found that this procedural information was not readily available elsewhere. This technical guide is based on our experiences and lessons learned during the process of establishing and operating regional ocean forecasting systems for the East Sea and the Yellow and East China Seas over the 5 year period of 2012-2016. The fundamental approach and techniques outlined in this guide are of use to anyone wanting to establish an automatic regional and coastal ocean forecasting system.
