The aim of this study was to investigate the level of dental infection control experienced by dental hygiene students in clinical practice institutions to identify problems and improve infection control in dental institutions. This study conducted online surveys targeting 269 dental hygiene students from universities that conducted clinical practice to determine the students' level of awareness regarding dental infection control in dental institutions and the reality of infection control in dental institutions. The results showed that dental hygiene students recognized the need for infection control and education about infection control at a high level. However, only 47% of the students were accurately informed about COVID-19. Basic instruments, periodontal instruments, and implant surgical instruments were sterilized after use for each patient, mostly by the institution, but 3-way syringe tips, preservation instruments and prosthetic instruments were more frequently reused without sterilization immediately after use. For dental infection control to be practiced at dental institutions, it is necessary to establish a systematic and safe infection control system, including infection control education, designation of infection managers, and provision of infection control guidelines.

We searched at the "PubMed.gov" and "jendodon.com" sites to conduct a literature review on dental instruments that are reused in clinical settings and on infection control involving pre-disinfection or sterilization cleaning/rinsing. The keyword "dental clean" was used for the Web search. We found the present official definition of instrument cleaning performed prior to disinfection or sterilization rather limiting ("removal of foreign matter (soil, organism, etc.) from the instruments"). Thus, we proposed to expand the definition to include the removal of oils applied to protect the metallic instruments and from corrosion, stains, and rust resulting from the frequent reuse of the instruments. Clinicians are found to clean their dental instruments (a) immediately after treating their patients or (b) following their treatment but not immediately afterward. In the latter case, we recommend presoaking to be added. Ultrasonic sterilization of 5~15 minutes is found to be more effective in terms of eliminating residual matter from the instruments compared to other methods. To check on the cleaning results, we recommend visual inspection, which can be quick and practical in clinical settings. The latest products being developed and marketed on the market address the related problems. Nonetheless, research must be continued on the effects of presoak, cleaning/rinsing, disinfection, and high-temperature or heating-based sterilization on the dental instruments and on dental clinicians' practices in cleaning, disinfection, and sterilization. We advise dental clinicians to select the proper cleaning methods and detergents for their instruments to help eliminate or prevent corrosion, staining, and rusting, to reduce the maintenance costs, and to ensure user-friendly instruments/apparatuses.

This paper describes a message model based on XML (eXtensible Markup Language) to present real-time data from sensors and instruments at manufacturing processes for web service. HTML (Hyper Text Markup Language) is inadequate for describing real-time data from process control plants while it is suitable for displaying non-real-time multimedia data on web. For XML-based web service of process data, XML format for the data presentation was proposed after investigating data of various instruments at steel-making plants. Considering transmission delay inevitably caused from increased message length and processing delay from transformation of raw data into defined format, which was critical for operation of a real-time system, its performance was evaluated by simulation. In the simulation, we assumed two implementation models for conducting the transformation function. In one model, transformation was done at an SCC (Supervisory Control Computer) after receiving real-time data from instruments. In the other model, transformation had been carried out at instruments before the data were transmitted to the SCC. Various tests had been conducted under different conditions of offered loads and data lengths and their results were described.

Increasing attention has been paid to rheological approaches in the food industry due to great awareness of the quality control of foods by objective analysis. Therefore, a lot of food manufacturers started to make a great of effort to instrumentally investigate the rheological properties of foods. However, the appropriate utilization of rheological instruments in the field of food science has been met with numerous technical challenges because of the lack of fundamental knowledge and knowhow. In this article, a variety of rheological instruments conventionally used in the food industry are reviewed. In addition, new rheological instruments that have been rapidly growing in popularity are introduced for potential applications. This article may provide an opportunity for the food industry to move toward the active utilization of rheological instruments.

The purposes of this review are that 1) what is the the concept of motor control, 2) what is the content of motor control assessment, and 3) which instruments or scales are used in clinical setting. Motor control is defined broadly the control of both movement and posture. And motor control focuses on understanding the control of movement already acquired. The purposes of assessment are screening, placement to apprpriate treatment program, program plan, evaluation, and progress assessment for individuals. The content of motor control assessment is included not only fexibility, tone, reflex & reaction, muscle strength, movement pattern, balance, gait, and functional ability, but also cognition, arousal, sensation, and perception. There ars many kinds of instruments or scales for assessing motor ability. Most of materials are tested the validity and reliability. But Korea has not own instrument for assessing motor ability. Therefore, Korea needs to develop the assessing tools for motor ability.

Objectives : This study was conducted to measure the effects of healthcare accreditation (HA) on the changes in infection control (IC). Methods : Questionnaires were e-mailed to 60 hospitals from 23 October to 23 December, 2011. Data were analyzed by SPSS 12.0. Results : Finally 50 hospitals (83.0%) were enrolled in the study: Seoul area (40.0%), tertiary (76.0%), and >500 beds (98.0%). Nine hospitals (18.0%) had a full time infection control nurse[ICN] with 300 beds. Among various factors, ICN (36.0%), hospital facilities (66.0%), instruments (32.0%) and supplies (88.0%) all improved. Hand hygiene increased (53.1% vs 83.2%, p<.001), but it was continued only in 34.1% of hospitals. Healthcare-associated infection (68.4%), multi drug resistant organisms (42.1%) and outbreaks (26.3%) decreased. Reasons for difficulties in satisfying the HA standards were inadequate support which included hospital facilities, instruments, budget, and a shortage of ICNs and healthcare workers (HCWs). Conclusions : HA had effects on the IC, but they were transient. Staffing in ICN and HCW staffing, hospital facilities, instruments, and supplies all need to be improved.

SCPI(Standard Commands for Programmable Instrument) is a standard command sets designed for controlling various types of instruments. In order to control FFT(Fast Fourier Transform) analyzing device using SCPI it is required to support sweep measurement function. We defined SCPI command set for FFT analysis and developed parser of defined command set using lex(Lexical Analyzer Generator) and yacc(Yet Another Compiler Compiler). After developing FFT analyzing test was performed with that parser. Up to audible signal frequency the result of FFT analysis was accurate and that result was agree with that of conventional FFT analyzer. As a result it is proved that various types of instruments including sweep measurement instrument can be controlled with appropriate SCPI command sets. Also when developing new instruments the method used in this experiment will contribute to reducing the time required to develop the SCPI parser and increasing reliability.
