The study was designed to investigate the anxious and depressive trends in the wives of alcoholic patients. For the purpose of assessment of anxiety and depression, Zung's self-rating anxiety-(SAS) and depression scales (SDS) were applied to the fifty wives of alcoholics, the latter were admitted to the psychiatric wards of Taegu Catholic Hosp. and Kyungpook National Univ. Hosp. from Jan 1 '84 to Sep. 30 '85 and were diagnosed according to DSM- criteria. And the two scales were also applied to the fifty wives of social drinkers as a control group. The results were as follows; 1) The mean SAS scores were 53.06±9.66 in the wives of alcoholics and 38.64±8.75 in the control group and so the difference was significant in anxious trends (p<0.01) between two groups. 2) The mean SDS scores were 54.00±10.20 in the wives of alcoholics and 42.64±7.80 in the control group and so the difference was significant in depressive trends (p<0.01) too between two groups. 3) As for the frequency order of the SAS items in the wives of alcoholics, they were apprehension, insomnia, restlessness and fear. As for the frequency order of the SDS items in the wives of alcoholics, they were confusion, decreased libido, decreased appetite and psychomotor retardation. 4) As for the wife's attitude toward her husband, nagging and interfering attitude was commonest(46%) in the wives of alcoholics in contrast to the gentle and tender attitude(48%) in the wives of social drinkers. 5) 62% of wives of alcoholics were dissatisfied with their sexual life but the degree of dissatisfaction was low to 8% in the wives of social drinkers.

The purpose of the study was to determine whether a 15.6mg.Kg ??' does of glutamate given one hour prior to incremental exercise test would reduce the lactate formation. Five well trained cyclists served as subjects in this experiment which included a placebo and glutamate trial. The subjects initially work on treadmill 200m/min for 3 minutes and here increased the workload by 20m/min every 3minutes until exhaustion. Blood lactate were collected from finger-tip. Subjects in the glutamate trial showed significantly lower lactate formation during exercise then they did in the placebo trial. In both groups no significant difference was found on heart rate. During the recovery lactate and heart, rate were unaltered in either the glutamate or placebo trials. In summary, glutamate ingestion may reduce lactate formation resultly improvement of performance.

This study explores the potential of improving the physical properties of poly(trimethylene terephthalate) (PTT) by inducing thermotropic liquid crystalline polymers. The TLCP was synthesized by polycondensation reaction of terephthaloyl chloride with corresponding diols. The TLCP used was copolymers containing random PTT groups on the polymer backbone. The PTT moieties were used to increse compatibility between the PTT and the TLCP. The TLCP showed the nematic phase above those melting temperature(T_m) The TLCP seems to act as plasticizers and nucleating agents in the matrix polymers Liquid crystalline phase did not reaveal any significant macrophase separation and thermal degradaton under the temperature of processing condition.

Investigation of corrosion assessment of hydrogen-rich water based cement mortars

Byung-Wan Jo 한양대학교 세라믹연구소 2017 Journal of Ceramic Processing Research Vol.18 No.4

This study primarily investigates the effects of hydrogen-rich water (HRW) on the rebar corrosion embedded in Portlandcement mortars. We comparatively assessed the performances of reinforced HRW-based mortars (HWMs) with respect tocement mortars fabricated from control water (CWM). The results indicate that the use of HRW significantly improves theanticorrosion properties of rebars embedded in cement mortars. Lower electronegative corrosion potential and the galvaniccurrent were observed in HWMs compared to CWM. The electrical resistivity (ER) of HWMs was observed to be higher thanthose of CWM. Moreover, the HRW reduces the setting times and improves mechanical properties. The generally improvedmechanical and anti-corrosion properties of HWMs are attributed to the formation of more cement hydrates with fewer voidsin the hydrogen-rich environment. Based on X-ray diffraction (XRD), Fourier transform infrared (FTIR), and scanningelectron microscope (SEM) analyses it was deduced that the use of HRW in Portland cement mortars produces a morecompact, dense, and durable microstructure with fewer voids due to a higher degree of hydration. The higher degree ofhydration in HRW leads to precipitation of greater amount of cement hydrates especially calcium hydroxide (Ca(OH)2) whichhelps maintain passive condition for reinforced bars.

Byung-Wan Jo,Yun-Sung Lee,Jung-Hoon Kim,Kwang-Won Yoon 한국콘텐츠학회(IJOC) 2018 International Journal of Contents Vol.14 No.3

To ensure safety of bridges, it is critical to inspect and assess physical and functional conditions regularly. Presently, most highway bridges in the U.S. are inspected visually. However, this method of inspection is often influenced by the bridge inspector`s knowledge and experience. So, reliability and accuracy of inspection results may be problematic. To solve such problems, an extensive number of robotics systems and image processing techniques for bridge inspection methods have been proposed. These robotics systems and image processing techniques are used to measure various bridge conditions, such as apparent damage, displacement and dynamic characteristics. This paper provides a comprehensive review of robotics systems and image processing technologies used in bridge inspection.

The nano scale of particles can result in dramatically improved or different properties from conventional grain-size materials of the same chemical composition. Therefore, it is practical to add nano-silica in particle form with 99.9% of SiO₂ in nano scale to improve the characteristics of cement mortar. The compressive strengths of cement mortar were evaluated at various water-cementitious ratio. Five different water-cementitious ratios were used including, 0.23, 0.25, 0.32, 0.35, and 0.48 and four contents of nano-SiO₂, particles, 3%, 6%, 9%, and 12% by weight of cement. The compressive strength of cement mortar with the addition of silica fume were also evaluated at w/㎝ ratio of 0.48 to compare with mortar containing nano-SiO₂ particles and three contents of silica fume were: 5%, 10% and 15% by weight of cement. The experimental results show that the compressive strengths of mortars with nano-SiO₂ particles were all higher than those of mortars containing silica fume at 7 and 28 days. It was demonstrated that the nano-particles were more valuable in enhancing strength than silica fume. This paper also analyzed some available examinations to monitor the hydration progress continuously, such as SEM observation, residual quantity test for Ca(OH)₂ and the rate of heat evolution. The results of the examinations indicate that the SiO₂ in nano scale behave not only as a filler to improve the microstructure, but also as an activator to promote pozzolanic reactions.

Study of intelligent load analysis system using genetic algorithm

Jo, Byung-Wan,Yoon, Kwang-Won,Lee, Yun-Sung,Choi, Ji-Sun Institution of Electrical Engineers 2014 IET intelligent transport systems Vol.8 No.5

<P>Roads play a crucial role in societal infrastructure as a main artery for the economy and lives of people. However, numerous deformations are caused by an increasing number of overloaded vehicles. Accordingly, an efficient managing system for preventing overloaded vehicles could be organised by using the road as a scale by applying a genetic algorithm to analyse the load and drive information of vehicles. First, accurate analysis of loads by using the behaviour of the road itself is needed to solve illegal axle manipulation problems of overloaded vehicles and to install intelligent embedded load analysis systems. Accordingly, to use the road behaviour, the transformation in this way was measured by installing an underground box-type indoor model, and an indoor experiment was conducted by using a genetic algorithm. After five driving sessions with each vehicle, 50 sets of dynamic responding data were attained. The recognition variables were calculated to be within the error range of 10%.</P>
