    In November 2007,in order to prevent the emergence of drug-resistant bacteria,we established a notification system concerning usage of broad-spectrum antimicrobials (carbapenems,fourth-generation cephalosporins,quinolones,and antimethicillin resistant Staphylococcus aureus (MRSA) agents),and linked it to a hospital information system.When ordering any of the antimicrobials mentioned above,physicians need to input the reason for prescribing it as well as the status of submitted bacterial cultures,and the period of administration is restricted to a maximum of four days including the day of order entry.
    In order to evaluate the system,we compared the amounts of regulated antimicrobial agents prescribed each month,the number of patients they were administered to,culture submission rate,the susceptibility rate of Pseudomonas aeruginosa for carbapenems and number of Clostridium difficile toxin A samples,between 1 year before the introduction of the system and 1 year after it was introduced.While there was no decrease in the amount of the regulated antimicrobials prescribed overall,there was a significant decrease in the amount of fourth-generation cephalosporins prescribed (p<0.05).The total cost of the antimicrobials did not decrease because the amounts of unregulated antimicrobials increased significantly (p=0.0002).The proportion of patients using regulated antimicrobials decreased significantly,from 17.3% to 13.8% (p<0.0001),and the frequency of ordering blood cultures increased from 26.1% to 53.8% (p<0.0001).In addition,the susceptibility rates of Pseudomonas aeruginosa for meropenem and imipenem/cilastatin significantly improved (p=0.0325,p=0.0188),and the number of Clostridium difficile toxin A samples decreased (p=0.0365).
    In conclusion,a hospital information system-linked prior notification system concerning broad-spectrum antimicrobials can make a useful contribution to preventing the emergence of bacterial resistance.

    A program for fully automatic conversion of line plots in scientific papers into numerical data has been developed. By the conversion of image data into numerical data, users can treat so-called 'spectra' such as X-ray photoelectron spectra and optical absorption spectra in their purpose, plotting them in different ways such as inverse of wave number, subtracting them from users' data, and so forth. This article reports details of the program consisting of many parts, with several deep-learning models with different functions, elimination of literal characters, color separation, etc. Most deep-learning models achieve accuracy higher than 95%. The usability is demonstrated with some examples.

    format. We validated the effectiveness of the system through the automatic classification of the relationship between face sway and saccades during simulated driving scenarios and comparing these results with manual assessments. Two male participants in their twenties, one wearing glasses and the other bare-eyed, were involved in the experiment to consider the potential impact of eyewear on measurement accuracy. The results demonstrated the feasibility of automatic classification using the measured data, with precision and F1 scores surpassing the minimum threshold for binary classification. This study establishes a foundational approach for integrating everyday technology in psychophysiological measurements, opening avenues for practical applications in monitoring concentration and drowsiness in real-time scenarios, such as driving.

        Diversity of vocabulary is high in the agricultural domain by the people different in a background such as farmer, distribution processor, researcher, and so forth. The diversity is a hurdle to share and exchange agricultural information. In order to lower this hurdle in Thailand, we considered to create the common agricultural vocabulary (CAVOC) in Thai. To realize this, we created the CAVOC translator. It is a mechanism to translate based on CAVOC in English and Japanese defined by Japanese research group. As a result, we confirmed that our system can easily create CAVOC in Thai, and eliminate obvious mistakes.

    A low-cost spectrometer, featuring a micro electro mechanical systems (MEMS) sensor, was designed and manufactured using digital fabrication techniques. The spectrometer was morphed into a zelkova leaf-shaped case using a three-dimensional printer. The control software, written in the Arduino sketch programing language, measured the flux of photons in the 400―800 nm range, at 1 nm resolution, every 5 min. The obtained data were saved on a micro SD memory card in the

    format. The spectrometer continuously operated for more than 3 d using a type B universal serial bus micro connector and a 10 Ah mobile battery. Four manufactured spectrometers were installed inside and outside of a tomato canopy in the experimental greenhouse of Wakayama prefecture, and continuously measured the spectroscopic flux of photons for nine d. The quantitative changes in the phytochrome photoequilibrium in the tomato leaves were estimated using the data from the continuous spectroscopic analysis. The effect of pruning under leaves on the illumination in the tomato canopy was quantified in terms of the leaf area index. We expect that the proposed low-cost and high-mobility spectrometer will be used in plant production fields.

    In this study, we developed a new system for measuring and monitoring the degree of an employee’s fatigue. The system is comprised of an ergometer, a pulsometer, a Kinect sensor, and a computer. It records the heart rate and the 3D motion of a subject during a pedaling exercise. This system is simple, inexpensive, and easy to use. This paper explains the construction of the system, and reports the results of verification experiments with a special focus on the use of the Kinect sensor. The results show that the Kinect sensor is a useful tool for recording body movement and that the system may be used to measure and monitor the degree of fatigue.

    Compared with their predecessor, the new systems (DataStation, DataCraft) that we have developed offer various advantages such as an increase in the number of types of seismographic equipment applications, the provision of an early earthquake detection process function and the capability to process a large quantity of data collectively. Early earthquake alarm seismographs will be installed along the meter gauge lines in the near future. Before the existing seismographs are replaced with these early earthquake alarm seismographs, we should confirm the suitability of the new system based on the analysis of past data.

    HIS (hospital information system) and PACS (picture archiving and communication system) have become widely popular in clinical offices, and use of RIS (radiology information system) in the department of radiology has spread, creating networking between HIS, PACS, and diagnostic systems. RIS receives patient data and order data from HIS and sends them to the diagnostic systems. On the other hand, the RIS sends the implementation record and accounting data to HIS. When receiving and transmitting of these data are done by the RIS, the event’s time is recorded in the RIS as attendant data. This paper proposes a way to analyze patient flow from the records of the event’s time. The method counts the number of the accepted examinations yi (i = 0, 1, … N) and the completed examinations zi every divided time ⊿t from the RIS work list, and computes the following three characteristic values related to patient flow. Those values are average expended time T; T = ( Σ zi i ・ ⊿t — Σ yi i ・ ⊿t ) / Σ yi ,number of exam queue qi; qi = Σ yi — Σ zi , and dissolved time of queue wi; wi = qi ・ ( ⊿t / zi ). The method analyzes patient flow of radiology using these characteristic values. It also performs a simulation of the flow in cases of equipment trouble.

    Recognizing human activity in real time with a limited dataset is possible on a resource-constrained device. However, most classification algorithms such as Support Vector Machines, C4.5, and K Nearest Neighbor require a large dataset to accurately predict human activities. In this paper, we present a novel real-time human activity recognition model based on Gaussian Naïve Bayes (GNB) algorithm using a personalized JavaScript object notation dataset extracted from the publicly available Physical Activity Monitoring for Aging People dataset and University of Southern California Human Activity dataset. With the proposed method, the personalized JSON training dataset is extracted and compressed into a 12×8 multi-dimensional array of the time-domain features extracted using a signal magnitude vector and tilt angles from tri-axial accelerometer sensor data. The algorithm is implemented on the Android platform using the Cordova cross-platform framework with HTML5 and JavaScript. Leave-one-activity-out cross validation is implemented as a testTrainer() function, the results of which are presented using a confusion matrix. The testTrainer() function leaves category K as the testing subset and the remaining K-1 as the training dataset to validate the proposed GNB algorithm. The proposed model is inexpensive in terms of memory and computational power owing to the use of a compressed small training dataset. Each K category was repeated five times and the algorithm consistently produced the same result for each test. The result of the simulation using the tilted angle features shows overall precision, recall, F-measure, and accuracy rates of 90%, 99.6%, 94.18%, and 89.51% respectively, in comparison to rates of 36.9%, 75%, 42%, and 36.9% when the signal magnitude vector features were used. The results of the simulations confirmed and proved that when using the tilt angle dataset, the GNB algorithm is superior to Support Vector Machines, C4.5, and K Nearest Neighbor algorithms.

    To help ensure the proper use of anti-Methicillin-resitant S.aureus (MRSA) drugs,we developed a system for prior notification of the use of these drugs,which is incorporated into the physician order-entry system.The setup also includes a Therapeutic Drug Monitoring (TDM) order-system,which is booted automatically when a physician orders anti-MRSA drugs other than linezoride.Our system allows pharmacists and members of the infection control team to make detailed checks of notifications and dosage regimens.
    In this study,we evaluated the notification system from the viewpoint of the proper use of anti-MRSA drugs.The total number of vials of anti-MRSA injections consumed decreased significantly after its introduction while the number of orders for TDM doubled as compared with before system introduction.Twenty percent of TDM orders through the new system were those which pharmacists had requested physicians to raise based on clinical data and drug regimens.By helping ensure the proper use of anti-MRSA drugs,the new system has improved clinical outcomes.

    A statistical system needs to be able to work with other systems in a flexible way and be easily extensible, because no one statistical system can implement all the features required by a wide variety of users. Recently, new ways of extending statistical systems have been brought about by the rapid development of software technologies, including the Java language. In this paper, we propose the use of several Java language techniques for realizing extensions of Jasp, a Java-based statistical system, and demonstrate three practical features of these extensions.
    The first practical feature is demonstrated in the ability to handle eXtensible Markup Language (XML) documents, which are the standard format for data transmission on the WWW. The second practical feature is the use of the Component Object Model (COM) interface of Microsoft Windows for communication, e.g., with Microsoft Excel. The third practical feature is the sharing of program resources from other statistical software products, and to perform this task we have extended Jasp by using a translator to execute functions written in the XploRe language.
