The vacuum evaporated Au films on soda-lime glasses were measured by the electrical conductivity with the variation of the annealing time, relative humidity, and temperature. Au films structures were observed by scanning Electron Microscope and X-ray Diffractometer. As the annealing time and temperature increased, the electrical conductivity was increased due to the migration or annihilation of defects, but the electrical conductivity was decreased as with the relative humidity increased. Au films by XRD and SEM examination showed the negligible effect of chemical reactions.

Time and places of hot spring-bath were diverse such as at succeeding to the throne, after abdication, during Crown Prince and etc. Generally, average staying time was about 20 days. Beside the healing purpose, hot spring-bath was taken to inspect the people's conditions, to reduce compulsory labor or tax, to carry out "Kwagoh", the old state examination or to console the people.

Histological examination of biopsy or postmortem lung tissue from patients with asthma usually reveals thickened airway walls. This change is called airway remodeling, which is characterized by airway eosinophilia, hyperplasia of goblet cells and smooth muscle, and subepithelial fibrosis [1,2]. In this study, we investigated the time-course functional, morphological, biochemical changes of remodeling in a ovalbumin (OVA)-induced murine chronic asthma model. (omitted)

Contrast-enhanced MR angiography has become a widely used method useful for clinical diagnosis. Early studies identified a number of technical issues, and many of these have been addressed with various MRI physics innovations over the last several years. The quality of the results is high enough that CE MRA is replacing conventional x-ray angiography methods at many institutions. Ongoing research is expected to provide further improvements in performance, most notably in additional reductions in examination time, in time-resolved 3D imaging, and in improved imaging of the peripheral vasculature with extended fields of view.

People frequently discuss equipment behavior in terms of time(age) and usage(mileage). Common examples are automobiles in which time and usageare usually included in discussion of longevity. In this paper a structured examination of bivariate measures of equipment utilization is performed and some useful model forms are developed and evaluated.

This paper examined dynamic characteristics of high speed trains using a time varying frequency transform. Fourier transform based methods are frequently used for the calculation of the dynamic characteristics of trains in the frequency domain, but they cannot represent the time-varying characteristics. Therefore it is necessary to examine their characteristics using a time-varying frequency transform. For the examination, the non-stationary vibration of wheelset, bogie, and carbody are measured using accelerometers and stored in a data aquisition system. They are processed with localization of the data by modulating with a window function, and Fourier transform is taken to each localized data, called the short-time Fourier transform. From the processed results, time varying auto-spectral density, cross-spectral density, frequency response, and coherence functions have been calculated. From the analysis, it is confirmed that the time varying frequency transform is a useful method for analyzing the dynamic characteristics of high speed trains.

Ultrasonographic examination of the stifle joint four clinically and radiographically normal adult dogs was performed before and after inducing the cranial cruciate ligament (CrCL) rupture of the bilateral stifle surgically. At Pre- or post-surgery, the hyperechoic patella ligament and the echogenic infrapatella fat interfered the visualization of the CrCL by the plain scanning method. However when the stifle joint was imaged by the scanning method injecting normal saline within the joint capsule, the hyperechogenic ligament was visualized by the separation of the infrapatella fat and the CrCL and the contrast effect of anechoic saline. When the stifle joint was imaged by the real time scanning method after the induction of the surgical rupture, fluttering of the ligament and anechoic area between the bone and the CrCL was identified due to the lack of tonicity and continuity of the ligament. Enlargement of the ligament because of its increased diameter as well as fluttering of the CrCL and the increased joint space's thickness was visualized. Consequently, confirming fluttering of the CrCL, increased ligament diameter and anechoic region between the CrCL and the bone, ultrasonographic examination is a valuable diagnostic tool as well as cranial drawer test and radiographic examination.

The purpose of this study was to examine the status of coffee intake in South Korea by analyzing the 4th Korea National Health and Nutrition Examination Survey. The results showed that 52.3% of Koreans consumed coffee at least once a day. Males consumed coffee more frequently than females and those aged 20-39 years and 40-59 years consumed coffee most frequently. Coffee drinkers consumed coffee two times a day and 138 mL each time on average. Coffee was mainly consumed either at home (44.8%) or in the workplace (36.1%); males drank coffee most frequently in the workplace and females did so at home. Milk coffee including coffee from vending machines and coffee mix (73.8%) was the most common type of coffee consumed. The results of this study would extend the understanding of the general status of coffee intake in South Korea, which has shown steady growth but remains a relatively overlooked research area.
