A prospective study was done to observe electrocardiographic changes induced by water-soluble contrast media during routine intravenous pyelography. Among total 161 patients, 71 patients were received Meglumine/Sodium Diatrizoate(Diatrizoate group), 60 patients were received Meglumine Iodamide(Iodamide group), and 30 patients were received 5% D/W solution(Control group). Intravenous injections were made in speed of 0.18ml per second in all patients including control group. Changes of heart rates and rhythms were monitored with Holter Recorder before, during and after injection, for 5 minutes, 2 minutes and 5 minutes each. The results were as follows: 1. In preinjection state, the heart rates were 73.5±8.8/Min. in control group, 73.8±9.7/Min. in Diatrizoate group, and 75.4±10.4 in Iodamide group, respectively. 2. In postinjection state, the heart rates were changed to 75.8±9.9 in control group, 82.6±14.5 in Diatrizoate group, and 83.4±12.4 in Iodamine group, respectively. The changes of the heart rates were interpreted as a significant increase in Diatrizoate group and Iodamide group(p<0.001), while in control group the changes were interpreted as an insignificant increase(p>0.05). There was no significant difference between Diatrizoate group and Iodamide group. 3. Increase of the heart rates more than 10 beats per minute were observed in 17/71(23.9%) in Diatrizoate group and 12/60(20.0%) in Iodamide. In control group, one patient showed increase of the heart rates more than 10 beats per minute. 4. In preinjection state, only two patients showed abnormal heart rhythm, one each in Diatrizoate group and Iodamide group. In postinjection state, 9 patients showed abnormal heart rhythm, 6 in Diatrizoate group(8.6%) and 3 in Iodamide group(5.0%). No one in control group showed abnormal rhythm either in pre or post injection state. 5. The average age of patients who showed no abnormal rhythm after injection was 40.0 years, while the average age of the patients who showed abnormal rhythm after injection was 55.9 years.

Investigation of Setting Process of Cementitious Materials Using Electromechanical Impedance of Embedded Piezoelectric Patch

이창준,이준철,신성우,김화중 한국건축시공학회 2012 한국건축시공학회지 Vol.12 No.6

In this study, the evolution of the electro-mechanical impedance (EMI) of a piezoelectric (PZT) patch embedded in fresh cement paste was investigated to discuss the possibility of monitoring the setting process of cement-based materials using an EMI sensing technique. A tailored thin square PZT patch was embedded in cement paste before casting, and EMI signatures of the embedded patch were continuously measured from casting up to 12 hours. A standard penetration resistance test was performed to compare and correlate the evolution of EMI during the setting process. The results showed that EMI responses differ according to the age of the cement paste, and that the behavior of the EMI resonance peak has a clear correlation with the penetration resistance of the cement paste. Based on the results, it is concluded that an EMI sensing technique using embedded PZT patch can be effectively applied to monitor the setting process of cement-based materials.

규칙기반 필터 및 기계학습을 이용한 AHRS용 자세추정 알고리즘 고찰

이창준,이정근 제어·로봇·시스템학회 2024 제어·로봇·시스템학회 논문지 Vol.30 No.5

Accurate orientation estimation is important in various applications such as robotics, unmanned vehicles, and biomechanics, in which an attitude and heading reference system (AHRS) is essential. The AHRS provides orientation by processing signals from an inertial measurement unit (IMU) consisting of a gyroscope, an accelerometer, and a magnetometer. Numerous rule-based filtering algorithms have been developed to estimate orientation based on IMU signals. However, several studies have recently been conducted to develop machine-learning-based algorithms. In this study, the methodology and estimation performance of IMU-based orientation estimation algorithms were reviewed by using rule-based filtering and machine learning approaches. A total of 37 papers were selected after searching the databases of IEEE Xplore, PubMed, ScienceDirect, and Google Scholar. Rule-based filtering algorithms were divided into Kalman and complementary filters depending on the weight calculation process. Approaches were also categorized into the direct estimation of the orientation and the correction of the error terms in the orientation or angular velocity. The machine learning algorithms were divided into the following: a combined method that estimated or corrected orientation by combining machine learning model with a rule-based filtering algorithm; and an end-to-end method that directly estimated orientation through the model. Results showed that although the machine learning algorithms could reliably perform attitude estimation, the rule-based filtering algorithms still demonstrated superior performance in the estimation of 3D orientation, including attitude and heading.

運動競技와 關聯된 選手들의 心理的 變化 分析

이창준,오기녕 濟州大學敎 體育科學硏究所 1997 체육과학연구 Vol.3 No.-

There are violent emotion-changes, that is joy and anger, concerned with the outcome of a game through hot competition, sacrifice. endurance, and physical pain, and the like in sports activities. These make athletes feel their anxiety and burden psychologically. These also bring much difficulties and barriers to them. Thus their psychology is important, because the outcome of a game is up to how to control their emotional and psychological changes. This study is to examine and analyze the psychological changes of middle school students. high school students and university students which have bad effects on their sports activity. The results from such an analysis are as follows; 1) In exercising, they have a tendency to feel their own technique, the honor of their school, and their coach's attention in this order. They are also eager to do their best. 2) In a sports game, middle school students take part in the game with feeling much more psychological difficulties and barriers than those of high school students and university students. 3) After a game, all classes of students reflect on it and make up their minds to do their best for the next game. This attitude is shown by unversity students more than any other class. 4) In the relationship between a athlete and a coach, there is little consultation. This tendency has to do with all classes of the students. Above all, high school students have much more distance from their coach than any other class. So far as the kind of sport games is concerned. this tendency has little to do with team athletes. To have high confidence between athletes and their coach there needs to be familiar consultation and the methods of teaching athletes needs to be according to their individual personalities and peculiarities.

Effects of Fiber Volume Fraction and Water/Cement Ratio on Toughness Development of Steel Fiber Reinforced Concrete

이창준,Lange, David A,이재용,신성우 한국건축시공학회 2013 한국건축시공학회지 Vol.13 No.1

Flexure toughness of Steel Fiber Reinforced Concrete (SFRC) shows a time-dependent characteristic due to the hydration process of the cement matrix in the SFRC system. The effect of two important factors, water/cement (w/c)ratio and fiber volume fraction, on the flexure toughness development of SFRC were investigated. Three different SFRC mixtures with hooked-end steel fibers were tested using a four-point bending testing configuration. Each mixture was tested at five different ages. The results showed that the post-peak toughness of SFRC developed at an earlier age than the first-crack toughness.

Liquidity Risk and Expected Stock Returns in Korea: A New Approach

이창준,장지원,강장구 한국증권학회 2012 Asia-Pacific Journal of Financial Studies Vol.41 No.6

We propose a simple way to capture the multidimensionality of liquidity. Our analysis indicates that existing liquidity measures have considerable asset specific components, which justifies our new approach. Constructing a two-factor model with the market and liquidity factor proposed in this paper, we find that our two-factor model explains well the cross-section of stock returns in Korea from 1987 to 2010, describing the liquidity premium, size and value effects that the CAPM and Fama-French three-factor model fail to explain. Our results also show that the role of liquidity risk on expected stock returns is especially pronounced during the post-Asian financial crisis period.
