The authors report a case of reactive arthritis that was caused by sexual contact as below example. A 36-year-old male visited our center due to sudden pain in wrist joint, the 3rd finger, knee joint, and achilles tendon. There were no specific abnormalities for the immunoserologic tests and magnetic resonance imaging; however, we found a positive test result for the polymerase chain reaction test of urine that identified Chlamydia trachomatis.

... nd various examinations, we considered the possibility of reactive arthritis, to the exclusion of alternate diagnosis. According to the our diagnosis, the patient was treated with antibiotics and nonsteroidal anti-inflammatory drugs and we found that the patient was getting better. Therefore the authors think that we have to contemplate the possibility of reactive arthritis and treat appropriately in patients with similar symptoms.

High Strength Concrete (HSC) has weakness that in a fire, it is spalled and brittles. The phenomenon of spalling is made by water vapor's being confined in watertight concrete. This study is aimed to evaluate explosive spalling properties of high strength concrete with □100×100×200 mm specimen and □400×400×1500 mm column. To prevent spalling of concrete, fireproof coating and PP fiber are used. As a result, □400×400×1500 mm column was prevented spalling likes □100×100×200 mm specimen. When

The analysis of the enthalpy changes for vaporization (ΔHvap) of Al-based metallic glass (MG) can provide insight into the origin of the MG's glass forming ability (GFA). The ΔHvap of three Al-based MGs, Al84.5 ± x(Y10Ni5.5)15.5 ± x, Al85 ± x(Y8Ni5Co2)15 ± x, and Al86 ± x(Y4.5Ni6Co2La1.5)14 ± x, (hereafter referred to as AYNx, AYNCx, and AYNCLx, respectively), is analyzed by measuring their weight losses below their glass transition temperatures. The relationship between ΔHvap and aluminum

... ntration exhibit minimum values in the range of 83-85 at.% of Al, and the ΔHvap increases, becoming saturated at 320-350 kJ/mol, as the percentage of Al deviates from this range. The depth of the enthalpy well, referring to the bottom of the parabolic graph of ΔHvap against the Al concentration, is proportional to the viscosity of clusters showing liquid-like behavior. The amount of weight loss is proportional to the concentration of these clusters. The cluster viscosity and concentration influences the overall viscosity of the MGs, and thus determines the GFA.

As video compression is one of the core technologies that enables seamless media streaming within the available network bandwidth, it is crucial to employ media codecs to support powerful coding performance and higher visual quality. Versatile Video Coding (VVC) is the latest video coding standard developed by the Joint Video Experts Team (JVET) that can compress original data hundreds of times in the image or video; the latest audio coding standard, Unified Speech and Audio Coding (USAC),

... ves a compression rate of about 20 times for audio or speech data. In this paper, we propose a pre-processing method to generate a two-dimensional (2D) audio signal as an input of a VVC encoder, and investigate the applicability to 2D audio compression using the video coding scheme. To evaluate the coding performance, we measure both signal-to-noise ratio (SNR) and bits per sample (bps). The experimental result shows the possibility of researching 2D audio encoding using video coding schemes.

The microbial communities and operational performances of a conventional anaerobic digester (AD) and an AD combined with microbial electrolysis cells (ADMEC) were investigated. Primary sludge and waste-activated sludge were used as substrates, and next-generation sequencing (NGS) techniques were used to analyze the microbial characteristics. The results show that ADMEC can achieve a faster stabilization rate, higher organic decomposition, and methane production performance than AD. After both

... e ADMEC and AD reached a steady state, microbial results revealed that Methanobacterium beijingense and Methanosaeta concilii were the dominant methanegenerating archaeal species in AD. In ADMEC, the relative abundance of methylotrophic methanogens (Thermoplasmata class), which has higher methane productivity than other methanogens, is significantly improved. For bacterial communities, an improved relative abundance of the Cloacamonas phylum, which is involved in amino acid fermentation, and in the Erysipelotrichi class, which grows well in environments with high organic concentrations, was observed in ADMEC. In summary, ADMEC is more efficient than AD because organic degradation and methanol production accelerated by bioelectrochemical reactions occur in ADMEC, leading to a favorable environment for the growth of methylotrophic methanogens in bulk solution.

The sorption affinity of iodide on organo-bentonite, modified with hexadecyl pyridinium (HDPy), was investigated with the iodine–starch method coupled with UV/Vis absorption spectroscopy. The iodine–starch complex method was optimized in terms of the reaction time and sample compositions, based on the UV/Vis absorbance. The batch sorption experiment for iodide on organo-bentonites, modified using two different loading amounts of HDPy, was conducted to analyze the influence of equilibrium time,

... iquid-to-solid ratio, and temperature, on the iodide sorption affinity. The experimental results regarding the removal capacity were further employed to derive the distribution coefficients of iodide on the organo-bentonites. The novelty of this work lies in the first application of the iodine–starch method coupled with UV/Vis absorption spectroscopy for analyzing the sorption behavior of iodide on modified bentonites. It is expected that the iodide-starch method can be complementarily employed for future research, with respect to the quantification of iodide.

To the best of our knowledge, this is the first report on thermophilic fungi isolated in Korea. Three species of thermophiles were isolated from compost and were identified as Myriococcum thermophilum, Thermoascus aurantiacus, and Thermomyces lanuginosus. They can grow at temperatures above 50 o C and produce high levels of cellulolytic and xylanolytic enzymes at high temperatures. Notably, the considerable thermostability of the endo-glucanase produced by T. aurantiacus has made the fungus an

... ttractive source of industrial enzymes. Thermophilic fungi can grow at temperatures ranging from a minimum of 20 o C to a maximum of 50 o C or at even higher temperatures. Thermophilic species are present in the natural environment in composts, aquatic sediments, piles of hay, stored grains, wood chip piles, and other accumulations of organic matter wherein the conditions are warm, humid, and aerobic [1] . A number of thermophilic fungi can survive in harsh conditions such as those with increased water pressure, an absence of oxygen, and under desiccation [2] . In a previous study, most thermophiles were isolated from composts [3]; their prevalence in composts can be explained by the high temperatures, humidity, and aerobic conditions within the compost. Moreover, the supply of carbohydrates and nitrogen in this mass of organic matter favors the development of thermophilic microflora [1]. Research Note Mycobiology 2014 June, 42(2): 181-184 http://dx.

Wheat yield is decreasing due to climate change, and a method to prevent decreasing yield during drought stress is desirable. In this study, wheat cultivars (Koso and Jokyung) were treated with 15% polyethylene glycol-6000 (PEG) and PEG + Si solution (6.5, 8.7, 13.1 and 26.1 mM). The effect of Si treatment on the alleviation of drought stress was measured using the germination test, shoot relative water content (RWC), seedling stage observation, and quantitative real time polymerase chain

... on (qRT-PCR). The results of root/shoot length ratio and shoot length ratio showed that Si treatment induced the alleviation of drought stress in Jokyung cultivar. The result of qRT-PCR showed the alleviation of drought stress in Koso cultivar. In addition, the results with shoot RWC and seedling stage observation showed that the alleviation effects of Si treatment was observed with both Koso and Jokyung cultivar at the high concentration of Si (26.1 mM). All these results suggest that Si treatment at a high concentration could be employed to alleviate drought stress in wheat.
