Data resource profile of an online database system for forensic mental health services

This paper introduces a forensic psychiatry database established in Japan and discusses its significance and future issues. The purpose of this Database, created under the Medical Treatment and Supervision Act (MTSA) Database Project, is to improve the quality of forensic psychiatry treatment. It can collect monthly data on “basic information,” “Orders and hospitalizations under the MTSA,” “Treatment process,” “Criminal and medical treatment history,” and “problematic behavior in the unit.” The online system has accumulated data on more than 8,000 items in 24 broad categories. Medical data are exported from the medical care assisting system of 32 designated inpatient facilities in XML format and then saved on USB memory sticks. The files are imported into the Database system client, which sends the data to the Database server via a virtual private network. This system minimizes errors and efficiently imports patient data. However, there is a limitation that it is difficult to set items that need to be analyzed to solve everyday clinical problems into the database system because they tend to change over time. By evaluating the effectiveness of the Database, and collecting appropriate data, it is expected to disseminate a wide range of knowledge that will contribute to the future development of mental health and welfare care.

Collection of excitation-emission-matrix fluorescence of aerosol-candidate-substances and its application to fluorescence lidar monitoring.

Fluorescence lidars have the potential to identify aerosols, but it seems that the basic data of the fluorescence spectrum of various aerosols appear to be inadequate for practical use in application of fluorescence lidar monitoring. We collected the fluorescence spectrum data of 61 powders with different substances as pseudo-aerosols and organized them as EEM (Excitation-Emission-Matrix) fluorescence data. Our interest was also in the artificial substances that are discarded around our surroundings and become aerosols. Four applications of the EEM fluorescence to fluorescence lidars were discussed; designing fluorescence lidars, reconstructing aerosol fluorescence spectrums measured by fluorescence lidar, searching for new substances for fluorescence lidar measurement, and developing a database of EEM fluorescence for identifying aerosol types measured by fluorescence lidar. All EEM fluorescence data and application software were stored in one USB memory and run in the BIOS (Basic Input/Output System) independent of a computer OS (Operating System) for ease of use. Aerosol identification software worked well in general, but we have also talked a bit about improvements.

Direct imaging of the SSD and USB memory drives heating by thermo-elastic optical indicator microscopy

The visualization of mass storage controllers and flash memory chips in the USB2.0, USB3.0 and solid state device (SSD) devices was performed using a thermo-elastic optical indicator microscopy system. Heat distributions corresponding to the various operation/loading parameters such as writing block sizes were analyzed, which was showed device behavior on heating. Direct measurements of the temperature by a thermocouple were implemented in order to investigate the operation thermal states of the devices under test (DUTs) in the idle regime. Heat temperature differences dependence on loading block size (0.25kB – 64MB) was found for all DUTs. In order to explain the heat variation dependence on block size a series of measurements of the DUTs transfer rates were performed. The data transfer rate is drastically changed depending on the transferred block size (8B – 128MB), (0.2kB/s – 7MB/s), (0.3kB/s – 21MB/s), (2kB/s – 92MB/s) and (3.7kB/s – 222MB/s) for USB2.0, USB3.0, HDD, and SSD, respectively.

Secure USB Authentication on Distributed Cloud Computing Environments

Objectives: Authentication is the first step of secure communication. Especially, cloud environment is a critical issue for user authentication because cloud storages have a lot of user credentials. Methods/Statistical Analysis: To solve this problem, security USB is released currently, especially in the public sector, use a mandatory system of security USB memory in the enterprise has been applied. However, information for user authentication or be stored in plain text in a specific area of the USB memory, vulnerabilities that can be authenticated bypassed by user interaction is found. Findings: Cloud storage services are getting popular and it must be secured. Otherwise, personal privacy could be compromised. Once username and password are compromised, valuable information will be in jeopardy. USB memory is small, cheap and the capacity ratio of price as a portable storage medium to provide a large capacity, it has secured already many users. Further, due to the small size, often lost or stolen accident, flows out the data in the USB memory, social problems such as major technology leakage of effluent and industrial personal information has occurred. Improvements/ Applications: To solve the vulnerability of such user’s authentication, by using the structure properties of the hash function and encryption algorithm and the storage medium presents a secure user’s authentication methods.

Competing technologies, competing forces: The rise and fall of the floppy disk, 1971–2010

The study examines the rise and fall of the floppy disk as a common data storage device from 1971 to 2010. The analysis led to the identification of three stages in the rise and fall of the floppy disk, i.e. the “new dawn”, 1971–1990s, the decline stage in the 2000s and then the phase-out period. From the 1970s to the 1990s, the floppy disk gained dominance and became a leading storage device propelled by its superior features and capacity relative to the old-fashioned punch cards and magnetic tape. Yet, by the early 2000s, it was on a path to terminal decline precipitated by the emergence of competing storage devices and limitations of the floppy disk. The study highlights the effects of the technological revolution which ultimately led to the floppy disk being superseded by more reliable, high-capacity and robust storage devices such as CD-ROM, DVD/Blu-Ray disks, USB memory stick and cloud computing. The study charts the transitions from the floppy disk to CD-ROM and then to cloud computing and the underlying drivers. The study led to the identification of multiple competing technologies and competing forces punctuated by events which, over time, helped to precipitate the decline. The implication for theory and practice is identified and examined.

E-cigarettes: Solution to a problem or a new menace itself."

Electronic cigarettes are products designed to deliver nicotine or other substances to a user in the form of a vapor. The modern e-cigarette arose from a 2003 invention by Hon Lik in China and as of 2015 most devices are made there. Typically, they are composed of a rechargeable, battery-operated heating element, a replaceable cartridge that may contain nicotine or other chemicals, and an atomizer that, when heated, converts the contents of the cartridge into a vapor. This vapor can then be inhaled by the user. These products are often made to look like such products as cigarettes, cigars, and pipes. They are also sometimes made to look like everyday items such as pens and USB memory sticks, for people who wish to use the product without others noticing

EMC Legacy II: the second effort at capturing past IEEE International EMC Symposium records

Virtualization for Cost-Effective Teaching of Assembly Language Programming

This paper describes a virtual system that emulates an ARM-based processor machine, created to replace a traditional hardware-based system for teaching assembly language. The virtual system proposed here integrates, in a single environment, all the development tools necessary to deliver introductory or advanced courses on modern assembly language programming. The virtual system runs a Linux operating system in either a graphical or console mode on a Windows or Linux host machine. Student feedback indicates that teaching with the virtual system has become progressively easier, clearer and more interesting while keeping staff support to a minimum. Since no software licenses or extra hardware are required to use the virtual system, students are able to carry their own ARM emulator with them on a USB memory stick. Institutions adopting this, or a similar, virtual system can also benefit by reducing the capital investment in hardware-based development kits, and by enabling distance-learning courses.

USB 메모리의 컨테이너ID를 이용한 PKI 기반의 개인키 파일의 안전한 관리 방안

Mosts user of internet and smart phone has certificate, and uses it when money transfer, stock trading, on-line shopping, etc. Mosts user stores certificate in a hard disk drive of PC, or the external storage medium. In particular, the certification agencies are encouraged for user to store certificate in external storage media such as USB memory rather than a hard disk drive. User think that the external storage medium is safe, but when it is connect to a PC, certificate may be copied easily, and can be exposed to hackers through malware or pharming site. Moreover, if a hacker knows the user`s password, he can use user`s certificate without restrictions. In this paper, we suggest secure management scheme of the private key file using a password of the encrypted private key file, and a USB Memory`s hardware information. The private key file is protected safely even if the encrypted private key file is copied or exposed by a hacker. Also, if the password of the private key file is exposed, USB Memory`s container ID, additional authentication factor keeps the private key file safe. Therefore, suggested scheme can improve the security of the external storage media for certificate.

A TPM-based Architecture to Secure VANET

Vehicular Ad hoc Network (VANET) is a special network of vehicles which can communicate with one another on the roads. Now days, VANET get increased attention by vehicle manufactures and researchers. However their deployment requires that security and privacy issues to be resolved, since they rely on wireless communication. In this paper, we are going to represent that security architecture built around TPMs can provide satisfactory solution. Moreover, this architecture does not require deployment of base stations along the roads. We will also show that how hardware device like USB memory stick will improve the anonymity in order to prevent unauthorized vehicle tracking.

BadUSB의 취약성 및 대응방안

To defend against information leakage or malware inflow by USB memory, security technologies such as copy protection and device control have being researched and developed. However, countermeasure are insufficient despite being recognized as a fatal security-hole for BadUSB presented at the Black Hat Security Conference 2014. To solve this problem, the countermeasures for BadUSB vulnerability are proposed.

The Polaris-H imaging spectrometer

Recently, H3D has designed and introduced a gamma-ray imaging spectrometer system named Polaris-H. Polaris-H was designed to perform gamma spectroscopy and imaging throughout nuclear power plants. It integrates a 3D-position-sensitive pixelated CZT detector (20mm×20mm×15mm), associated readout electronics, an embedded computer, a 5-h battery, and an optical camera in a portable water-proof enclosure. The total mass is about 4kg, and the system startup time is 2min. Additionally, it has a connection for a tablet, which displays a gamma-ray spectrum and isotope-specific images of the gamma-ray distribution in all directions in real time. List-mode data is saved to an external USB memory stick. Based on pixelated depth-sensing technology, spectroscopy is routinely better than 1.1% FWHM at 662keV, and imaging efficiency at 662keV varies less than a factor of two for all directions, except through the battery. Measurements have been performed in contaminated environments, in high radiation fields, and in cramped quarters.

Does ownership duration really matter? – Experimental study

This study tests experimentally how ownership duration affects the value attributed to different items, like a USB memory stick or a lottery ticket. Holding the item for 2 weeks increased the value of a lottery ticket but not the value of a USB memory stick. We argue that in the case of utilitarian items (such as USB memory stick), the holding time has no effect on the value since the owner can benefit from them while they are in his possession.

MinION nanopore sequencing identifies the position and structure of a bacterial antibiotic resistance island.

Short-read, high-throughput sequencing technology cannot identify the chromosomal position of repetitive insertion sequences that typically flank horizontally acquired genes such as bacterial virulence genes and antibiotic resistance genes. The MinION nanopore sequencer can produce long sequencing reads on a device similar in size to a USB memory stick. Here we apply a MinION sequencer to resolve the structure and chromosomal insertion site of a composite antibiotic resistance island in Salmonella Typhi Haplotype 58. Nanopore sequencing data from a single 18-h run was used to create a scaffold for an assembly generated from short-read Illumina data. Our results demonstrate the potential of the MinION device in clinical laboratories to fully characterize the epidemic spread of bacterial pathogens.

Purification of Histidine‐tagged and GST tagged proteins using ÄKTA™ start (LB264)

Expression of recombinant proteins using affinity tags is a commonly used purification strategy. Histidine and glutathione‐S transferase (GST) are the most common and versatile of these tags. Histidine tags are small and therefore less disruptive to the protein structures and functions. GST tags enhance solubility of the target protein, hence improving the yield.Manual purification of tagged proteins often face issues with time to purify, low reproducibility and low yield etc. In addition a researcher who is purifying manually needs to spend time in setting‐up the run, sample loading, collection and measuring the final protein concentration.We describe here the purification Histidine‐tagged and GST‐tagged protein using ÄKTA start with Frac30 fraction collector and UNICORNTM start system control software.We purified an N‐terminal Histidine tagged protein expressed in E.coli on a pre‐packed HisTrapTM FF 1mL column. The purification method was completely automated for unattended operation by applying large volume of sample using pump and collecting peak fractions using Frac30 fraction collector. We have consistently obtained high levels of purity (> 95%) of the tagged protein, which is 1.6 fold higher when compared to a conventional manual purification method.In the second example, we describe the purification of GST tagged protein expressed in E.coli on a pre‐packed GSTrapTM FF 1ml column using ÄKTA start with Frac30 fraction collector. The target protein was purified using pre‐defined method workflow available from the instrument display. The result file that was stored on USB memory stick is imported for viewing and report generation using UNICORN start software.ÄKTATM start is the newly developed laboratory scale protein purification system that can address the challenges faced during manual purification. Automated purification of tagged proteins has showed higher yields and purity with high consistency.

Design of an Intelligent Point-to-Point Swing Arm Controller

The point-to-point swing arm test is very important for large arms which have swing arm movement. Traditional point-to-point swing arm controller is relay control mode. The mode has many shortcomings, such as big volume, high power consumption, low stability, and so on. An intelligent point-to-point swing arm controller, using MCU as the control core, was designed for this reason. It was mainly composed of switch signal detecting module, solenoid valve drive module, USB storage interface module and MCU control module. According to the requirements of test, the controller was able to detect the valid signal of limit switch and control commutation operation of solenoid valve, meanwhile it could record the movement time between one point and another point, the time the arm swayed and the moment information, and these above information would be stored in USB memory. It has some advantages of small size, low power consumption, high stability and flexible functions.
