Purpose: $^{18}F$-FDG PET is to evaluate the tumor using glucose metabolism. Blood Glucose Level (BGL) is important factor that affects on a result of examination. But it often appears the distort result on diabetic patient due to a failure of BGL control. The aim of this study is to make a effective guideline for diabetic patient prescribed $^{18}F$-FDG PET and improve accuracy and reliability of examination. Materials and methods: A subject of study is 69 diabetic patients and divided them into 3 groups; 1) BGL is less than 120 mg/dl & performed PET, 2) BGL is over than 120 mg/dl & performed PET, 3) BGL is over than 120 mg/dl & not performed PET. And we investigated the type of diabetic medications and the time of dosage, whether they have meal or not. And we analyzed SUV of liver and mediastinum to recognize the effect of BGL on PET images. Results: As a methods to diabetic control, Amalyl showed high percentage of 27.5% in oral medication and Humulin R showed 14.5% in insulin. Their peak time was 2-3 hrs, 2-4 hrs and duration time was 24 hrs, 5-7 hrs. The number of that had a breakfast was 16, 7 mens (43.8%) couldn't perform PET as over 120 mg/dl and 5 mens (31.3%) performed PET as less than 120 mg/dl after they took a medication. When we set the SUV of normal for 1.5-2.0, 1.0-1.5 on liver and mediastinum, the percentage out of the range was 31.8%, 52.9%, 62.5% in 120-139 mg/dl, 140-159 mg/dl, 160-200 mg/dl respectively.

With the popularization of big data environment, big data have been highlighted as a key information strategy to establish national spatial data infrastructure for a scientific land policy and the extension of the creative economy. Especially interesting from our point of view is the cadastral information is a core national information source that forms the basis of spatial information that leads to people's daily life including the production and consumption of information related to real estate. The purpose of our paper is to suggest the scheme of big data analytics with respect to the articles of cadastral resurvey project in order to approach cadastral information in terms of spatial data integration. As specific research method, the TM (Text Mining) package from R was used to read various formats of news reports as texts, and nouns were extracted by using the KoNLP package. That is, we searched the main keywords regarding cadastral resurvey, performing extraction of compound noun and data mining analysis. And visualization of the results was presented. In addition, new reports related to cadastral resurvey between 2012 and 2014 were searched in newspapers, and nouns were extracted from the searched data for the data mining analysis of cadastral information. Furthermore, the approval rating, reliability, and improvement of rules were presented through correlation analyses among the extracted compound nouns. As a result of the correlation analysis among the most frequently used ones of the extracted nouns, five groups of data consisting of 133 keywords were generated. The most frequently appeared words were "cadastral resurvey," "civil complaint," "dispute," "cadastral survey," "lawsuit," "settlement," "mediation," "discrepant land," and "parcel." In Conclusions, the cadastral resurvey performed in some local governments has been proceeding smoothly as positive results. On the other hands, disputes from owner of land have been provoking a stream of complaints from parcel surveying for the cadastral resurvey. Through such keyword analysis, various public opinion and the types of civil complaints related to the cadastral resurvey project can be identified to prevent them through pre-emptive responses for direct call centre on the cadastral surveying, Electronic civil service and customer counseling, and high quality services about cadastral information can be provided. This study, therefore, provides a stepping stones for developing an account of big data analytics which is able to comprehensively examine and visualize a variety of news report and opinions in cadastral resurvey project promotion. Henceforth, this will contribute to establish the foundation for a framework of the information utilization, enabling scientific decision making with speediness and correctness.

The Electric Multiple Unit (EMU) has many types of door system such as sliding door, plug door etc.al. according to customer's requirements. The sliding door is widely used in Korea but has weak point in the noise problem. In the low operation speed, the noise coming from outer side of the EMU is not an important factor. As the speed is higher than before, noise is increased and make a problem. The main cause of noise is the imperfect air tightness in the EMU. The plug door system has advantages for the noise reduction characteristic in the high speed area. We have been developing electric plug-in door. The door is controlled by Door Control Unit(DCU) following the order of Automatic Train Protection (ATP) that is a kind of train signalling system. DCU has to simultaneously open and close the doors and the operation of it is related to the passengers safety. So DCU is a safety device that is important to reliability and safety. DCU is composed of several devices of control, motor driving, Input/Output, communication and power. In this paper, we will describe the functions, characteristic, requirement, subsystem and test results of DCU used for the electric plug-in door.

Background : It is increasing the concern for patient satisfaction as a customer information. This study was planned to investigate the activities related to patient satisfaction survey at the Korean hospitals. Methods : We performed the nationwide survey on 235 general hospitals by using the self-administrated checklist from Sep. 9 to Oct. 9, 1996. The response rate were 50.2%. We analyzed the descriptive statistics and chi-square test by SAS software on 118 hospitals. Results : First of all, 62.7% of study hospitals showed to conduct the patient satisfaction survey, and most of hospitals which did not conduct it had a plan to do it within 5 years. The reason that hospitals did not conduct satisfaction survey was due to a lack of administrator's interest or adequate questionnaire form. Second, the bigger, public and being more located in the big city or opened more than 10 years, the more hospitals conducted the patient satisfaction survey. Also, patient satisfaction survey was mainly handled by planning dept. or administrative team. Third, most hospitals had their own way of making questionnaires without proving reliability and validity. The results of the survey were applied to hospital management timely, and were mostly reported to top manager level. Most CEO concerned about the results of satisfaction survey. Fourth, the staffs in charge of survey had problems such as skill related to data analysis and development of questionnaire and they suggested that this problems could be solved through inducing the implementation of the survey results on hospital management, support for the development of standardized questionnaires and increasing the top manager's interests. Fifth, most questionnaires composed of lots of questioning items on hospital equipments and environment, and kindness of hospital employee to patients. Conclusions : Although this study had some limitations in generalization due to low response rate in big hospitals, it is meaningful to find the present state and the problems related to patient satisfaction survey of the general hospitals. We can conclude that there are increasing the concern for patient satisfaction survey among the hospitals nationwide, and it can be needed for technical support related to development of survey tool or method.

The damages from security accidents continue to increase as technology leaks from suppliers cause risks to the management of large companies, which are their customers, and their image and reliability to fall. However, the current industrial structure is practically impossible for large companies to form their own businesses and strategic alliances with business partners are essential, but it is changing into an industrial structure where the exchange of information is increased and the dependence of the information system is maximized, as well as legal demands and demands from stakeholders are increasing due to the complexity of the work process and the strengthening of security-related laws. The status of technology protection of small and medium-sized enterprises shows that they are not equipped with a security system due to relatively poor environment and financial difficulties compared to large enterprises, whereas the industrial structure between large and small business partners is indispensable for sharing the IT system, and the security system of large business, which is a customer company, should be improved by considering the fact that it is impossible to maintain security system between large businesses. Thus, the government intends to examine the system for shared growth of small businesses and the model for evaluating the capabilities of various agencies for information protection, and propose measures to introduce the certification system for small business partners.
