The effect of pigment-resin-solvent interaction on dispersion of pigment has been studied. The solubility parameter of TiO_2 pigment, determined in terms of suspension behavior of pigment in various solvents, was 10.27 (cal/cc)^1/2(δ_d = 8.23, δ_p = 3.45, δ_h = 5.10). The solubility parameter of Acryloid B-44, determined using rheological parameters of resin solution in different solvent, was 9.4 (cal/cc)^1/2. The solvent showing weaker interaction with pigment increased the adsorption of resin on to the pigment, resulting in higher dispersibility and higher storage stability of dispersion.

To determine knowledge and recognition of the patients and the staffs on the cockroaches in hospitals, a survey was made toward them by using questionnaires from July 1994 to September 1994. The patients and the staffs were randomly selected for the survey from 6 hospitals which have over 200 beds in Pusan and Kyungnam area. The sample numbers of the patients and the staffs were each 150. However, 115 and 133 questionnaires from the patients and the staffs, respectively, were used for the data analysis. The results obtained were as follows. 1. The cockroach detection rate by the patients was 60.7% of them. The detection rates by female patients and the younger patients were significantly higher than those of male patients and the older patients(p<0.005). 2. 26.6% of the patients and 24.8% of the staffs have had allergies from the cockroaches. Also, 78.3% of the staffs have mentally suffered from nuisance by the cockroaches(p<0.05). 3. The degree of the knowledges on the cockroaches and the control methods were 70/100 at the patients and 69/100 at the staffs. Also, their knowledges were mainly obtained from mass media(45.0%). 4. The cockroach control was performed by 88.8% of the investigated hospitals and 55.1% of them contracted with the pest control operators to reduce the cockroach populations in the hospitals. The operators used mainly insecticidal baits for the cockroach control(47.0%). 5. The management and the education program for the cockroach control were required by the patients(80.5%) and the staffs(84.0%) in the hospitals.

Addition of EI systems to the synchronization networks is being conducted as the digital transmission in Korea is changing from TI to EI. In this study, the quality of the synchronization signal of DOTS's of each toll office which is under the early stage of transition to the EI synchronization networks is measured and analyzed. In particular, the purpose of this study is to find out how to speed up the deployment of the EI synchronization networks by comparing the quality of the TI and EI synchronization signals. According to the results, the TI and EI synchronization signals distributed from KRF directly have no difference in quality. In addition, the synchronization signal redistributed from DOTS which is phase-locked on KRF and the synchronization signal from KRF directly have no difference in quality. Hence, it is concluded that there will be no problems in quality of synchronization resulting from the gradual transition to El while making the most of the current TI facilities.

The most essential point on the ion nitriding of stainless steel is to eliminate passive film. Therefore, it has been studied that passive film was eliminated by changing pre sputtering parameters. Then pre sputtering parameters were pressure, holding time and gas mixing ratio. The degree of elimination of passive film was characterized by using AES and its crystallographic structure by means of XRD. Mechanical property and microstructure were determined by Vickers hardness test and SEM. The results obtained from the experiment are summarized as follows ; 1. Sputtering pressure and holding time had no relation with the behavior of nitride layer and the most effective parameter was observed as gas mixing ratio. 2. The retained O₂concentration in vacuum atmosphere was decreased by deoxidization of H??ion with gas addition. H??ion prevented the oxidization on the surface of stainless steel and reduced oxygen potential of sputtered oxide from the surface. 3. For pre sputtering, H₂gas was more dominant in the nitriding rate than Ar and N₂gas. 4. Ar/H₂gas mixture which gas mixing ratio was 1/2(vol%) was the most effective in all pre sputtering conditions. It was estimated that this resulted from the combination of the mechanical reaction by bombardment massive Ar??ion and the chemical reaction by deoxidization of H??ion. 5. For ion nitriding of the oxidized stainless steel thickness which diffuse easily nitrogen into stainless steel. In this study, the mechanical reaction by bombardment massive Ar??ion was more effective parameter than chemical reaction by deoxidization of H??ion to eliminate oxide layer which grow up to a critical thickness.

Background: Recently, patients' demands for emergency medicine are increasing, and most of prehospital medical care, including basic life support, cardiopulmonary resuscitation and triage, are provided by paramedics or emergency medical technicians. Evaluation of the adequacy of prehospital management and triage has become important for improving the quality and the effectiveness of the emergency medical system. Methods: The 202 patients who were transferred by ambulance with paramedics, nurses, or emergency medical technicians to the Emergency Department in Gil Medical Center from July 1, 1999, to September 31, 1999, were enrolled. This study was conducted prospectively by using the emergency physician,s log and newly devised protocols recorded by paramedics or nurses. Results: 1) Male to female ratio was 1: 0.8, and the peak age of the patients were the 4th(18.8%) and 6th decade(15.3%). 2) Of the 202 patients, 84 patients were transferred for trauma and 118 for medical problems. The mean transfer time was 6±1.73 minutes. 3) The validities of prehospital triage and decisions using the trauma severity measure and the disease severity measure, were 33.3% in trauma patients and 57.6% in medical patients.4) The results for the adequacy rate in prehospital management analyzed by using the rate of necessity of treatment. performance of treatment, and adequate treatment were as follows: oxygen supply.38.1/41.6/93.8 ; wound dressing. 19.3/71.8/92.9 ; immobilization of the cervical spine, 15.8/56.3/92.9 ; application of a spinal board. 12.9/42.3/72.7 ; application of a splint, 9.9/50.0/60.0 ; manual maintenance of an airway. 9.9/55.0/63.6 ; and CPR, 4.5/66.7/0. 5) Kind of ALS(Advanced Life Support) were not conducted(peripheral IV, EKG. intubation, medical administration. defibrillation, pacing). The rates of necessity of treatment were as follows: peripheral IV, 40.6%; ECG monitoring, 23.3% ; endotracheal intubation, 8.9% ; medical administration, 8.9% ; defibrillation. 3.5%; and pacing. 1.5% Conclusion: The adequacy of prehospital triage and decisions using trauma and disease severity measures was relatively low. To improve the adequacy of BLS(Basic Life Support) and to increase the performance of ALS(Advanced Life Support), we must create challenges to develop new protocols and to supplement new equipment.

A thin film Pt-RTD(resistance temperature device) was fabricated by using DC magnetron sputtering and laser patterning. A study was fulfilled to adjust the TCR(temperature coefficient of resistance) to 3850 ppm/℃ which is IEC751 standard and the influence of oxygen addition(0 ~ 20 %) on TCR was measured. The resistance of Pt-RTD was set to 1000 Q at 0 ℃ using laser patterning and trimming. The analyses of XRD and AES were used to characterise the platinum thin film. The TCR of Pt-RTD was measured by a high precision oil bath. When the addition of oxygen flow rate was 1 %, TCR was 3850 ppm/℃.

Monosodium urate crystal-induced triggering receptor expressed on myeloid cells 1 is associated with acute gouty inflammation

Lee, Jennifer,Lee, Seon-Young,Lee, Jaeseon,Lee, Juhyun,Baek, Seungye,Lee, Dong-Gun,Kim, Eun-Kyung,Lee, Sung Hak,Cho, Mi-La,Kwok, Seung-Ki,Ju, Ji Hyeon,Park, Sung-Hwan Oxford University Press 2016 Rheumatology Vol.55 No.1

<P>Objective. Triggering receptor expressed on myeloid cells 1 (TREM-1), which amplifies the inflammation elicited by the Toll-like receptor pathway, was originally implicated in sepsis and bacterial infection. However, it has been suggested that TREM-1 may also play an important role in non-infectious inflammation. The present study was conducted to investigate whether TREM-1 is involved in human acute gouty inflammation. Methods. A total of 37 gout patients were recruited between March 2011 and January 2014 from Seoul St Mary's Hospital. The expression of TREM-1 on mononuclear cells was assessed using FACS analysis, immunostaining and real-time RT-PCR. To block the TREM-1 signal, soluble TREM-1 (sTREM-1) or the synthetic blocking peptide LP17 was used. The concentration of sTREM-1 was assessed by ELISA. Results. FACS analysis and real-time RT-PCR demonstrated that TREM-1 expression was higher in the SF mononuclear cells of acute gouty arthritis patients than in peripheral blood mononuclear cells (PBMCs). Immunohistochemical staining of tophi tissues revealed TREM-1 expression, with confocal microscopy demonstrating TREM-1 expression on tophi tissue macrophages. We also demonstrated that MSU treatment induced TREM-1 expression on the PBMCs of acute gout patients in vitro. Although blockade of TREM-1 did not directly suppress MSU-induced IL-1 beta production of PBMCs in vitro, the concentration of soluble TREM-1 was higher in the SF of gout vs OA patients and was positively correlated with serum CRP. Conclusion. TREM-1 is induced by MSU and is associated with the inflammation of human acute gouty arthritis.</P>

Holt-Oram Syndrome is an autosomal dominant disorder characterized by the association of upper-limb abnormalities and congenital heart disease. A woman with no family history of genetic disease underwent antenatal sonography at 27 weeks' menstrual age to screen for fetal anomalies. Ultrasonography revealed abnormalities in the upper limbs. The limb abnormalities included abscence of bilateral thumbs and radius: the left humus was short. Pregnancy termination was performed. The postnatal chromosomal analysis revealed a normal 46XX karyotype and the autopsy finding confirmed the Holt-Oram syndrome. We report a case of Holt-Oram Syndrome in fetus with unaffected parents with brief of the literatures.
