Purpose: The aim of this study was to translate the original English version of tampa scale for kinesiophobia for temporomandibular disorders (TSK-TMDs) for cultural equivalency into Korean language and to evaluate the reliability of the Korean version of the TSK-TMD among symptom free subjects. Methods: The original version of TSK-TMD was translated and cross-culturally adapted following international guidelines. A total 90 subjects (50 women, 40 men) were participated to fill out the questionnaire. The internal consistency and test-retest reliability with a one- or two-week time interval were evaluated. Results: The internal consistency of TSK-TMD of the original and the modified 12-item TSK-TMD were 0.866, and 0.858, respectively using the Cronbach's alpha coefficient. And the internal consistency of activity avoidance (AA) and somatic focus (SF) subscale were 0.838 and 0.807 assessed with Cronbach's alpha indicating excellent reliability. Test-retest reliability of the original TSK-TMD measured by the intra-class correlation coefficient (ICC) was 0.764, and coefficients value of the 12-question TSK-TMD was 0.752. Test-retest reliability of AA subscale was 0.722 and SF subscale was 0.677 measured by ICC. Conclusions: The Korean version of the TSK-TMD questionnaire was found to be a reliable instrument and successfully translated to Korean language. There are no significant differences between overall and modified version of TSK-TMD. It can be used as a valuable instrument for the analyses of the psychosocial aspects of the TMD patients in Korea.

Purpose: To compare the effectiveness of the magnesium (Mg)-enriched formula vs. control formula in constipated infants. Methods: An open-label, interventional, and the comparator-controlled study was conducted to evaluate the effectiveness of the Mg-enriched formula in formula-fed infants ${\leq}6$ months old presenting with functional constipation according to modified Rome IV criteria. Infants were randomized 1:1 to intervention or control formula for 30 days. Parents recorded stool consistency (hard, normal, or watery) and frequency on days 1-7 and 23-29. Physicians recorded patient baseline characteristics and performed the clinical examination at the time of three patient visits (baseline, day 8, and 30). Results: Of the 286 recruited infants, 143 received the Mg-rich formula and 142 received the control formula. After 7 days, significantly more infants had stools with normal consistency with the Mg-rich formula compared to the infants fed with the control formula (81.8% vs. 41.1%; p<0.001). The number of infants passing one or more stools per day was increased at day 7 in the Mg-rich formula group (86.7% vs. 68.2%; p<0.001). At days 7 and 29, >25% of infants responded completely to the Mg-rich formula compared to <5% of infants fed with the control formula (p<0.001). Parents of infants in the Mg-rich formula group were very satisfied with the treatment (80.8% vs. 10.2%), with the majority willing to continue treatment after 30 days (97.9% vs. 52.6%; p<0.001). Conclusion: The Mg-rich formula significantly improved stool consistency and frequency compared to the control formula in constipated infants.

Wireless broadcast environments has character that a number of mobile client can receive data streaming from central server no matter how they are so many. Because it is asymmetric bandwidth in that uplink and downlink bandwidth are different. This advantage helps wireless broadcast environments is used in many applications. These applications work almost read operation and need control concurrency using transaction unit. Previous concurrency control scheme in single channel is not adapted in multi channel environments because consistency of data are broken when a mobile client tunes in a broadcast cycle in a channel and then move into another channel and listen to different broadcast cycle with already accessed broadcast cycle. In this paper, we propose concurrency control for read-only mobile transactions in multiple wireless broadcast channel. First of all, we adapt index and data dedicated channel and propose LBCPC(Longest Broadcast Cycle Per Channel) as new unit of consistency. In index dedicated channel, it is repeatedly broadcasted data in same BCPC(Broadcast Cycle Per Channel) until LBCPC. And mobile transaction executes validation using control information every LBCPC. As a result, consistency of data is kept and average response time is shorter than one in single channel because waiting time for restart reduces. And as control information is broadcasted more frequently than in single channel, it is guaranteed currency about data accessed by transaction. Finally, according to the simulation result, we verify performance of our scheme in multi channel as comparing average response time with single channel.

A robust end time optimal conかof strategy for dual-stage servo system is presented. The time optimal trajectory for a mass-damper system is determined and given os a reference input to the servo system. The feedback controller is constructed so that the fine stage tracks the coarse stage errors and robustly designed as the“perturbation compensated sliding mode control(PCSMC)”law, a combination of slid-ing mode controller(SMC) and perturbation observer(PO). In addition, a null motion controller which regulates the fine stage at its neutral position is designed based on the“dynamic consistency”So, the overall dual-stage servo system exhibits the robust and time-optimal performance. The inherent merit and performance of the dual-stage system will be shown.

One of representative techniques for compensation of LC's slow response characteristic is the Response Time Acceleration (RTA) technique. The conventional data definition for the RTA is based on the manual measurement and thus it takes long time. Therefore it is almost impossible to use panel specific compensation data in MP line. We have developed a new automated measurement system and flicker minimization for this purpose, which could achieve dramatic measurement time reduction, consistency over different operator, and optimized values as well. This system laid the groundwork for the application of image quality enhancement technologies to panels individually, and using this system, we can expect very uniform image quality for all LCD panels.

In this paper, we present a useful system to manage the quality documents, using the concept of hypertext in HANGUEL wordprocessor, In order to develop this system, we classify all manuals, procedures and forms into files. A relationship chart of these files is constructed and files are hyperlinked according to this chart. We apply this quality document management system using hyper- text to a small precision manufacturing firm by analyzing its all kinds of quality documents. We confirm that this system effectively reduces the handling time of quality documents and supports revising task of quality documents with consistency.

We considered a change-point hazard rate model generalizing constant hazard rate model. This type of model is very popular in the sense that the Weibull and exponential distributions formulating survival time data are the special cases of it. Maximum likelihood estimation and the asymptotic properties such as the consistency and its limiting distribution of the change-point estimator were discussed. A parametric bootstrap method for finding confidence intervals of the unknown change-point was also suggested and the proposed method is explained through a practical example.

A microscopic study was carried out to get the fundamental informations for the ozone deinking technology. The differential interference microscopic observation showed that ozone treatment was helpful to detach the toner ink from the surface of pulp fiber. The modifications of fiber surfaces by ozone treatment were observed with scanning electron microscope. Modification of fiber surfaces was not severe at the early stage of ozone treatment, but it increased with ozone treatment time and pulp consistency, Therefore, it would be possible to improve the properties of deinked pulp by controlling the condtion of ozone treatment.

The development of a microprocessor-controlled centreless grinding station has opened the way for the production of automobile camshafts-from raw casting to precision-finished part-as a fully automated operation. This results in manufacture to finer tolerances, with part-to-part consistency and a floor-to-floor time of half that needed for alternative production methods. Shafts with a grinding length of up to 700 mm can be processed.
