For this study to determine the effect of modules instruction of sewing in elementary schools, two fifth-grade classes were selected: one as the experimental group receiving modular sewing lessons, and the other as the control group receiving conventional sewing lessons, for a period of four weeks. The cognitive, functional, and definitive aptitudes of each student from both groups wee assessed right before and after the experiment. The result showed that functional and definitive achievements were higher in the experimental group while cognitive achievement did not indicate any significant difference. In conclusion, a modular sewing lesson, coping with difference in individual learning abilities, was found to be a better educational method in functional and definitive areas, but not in cognitive area.

고 아밀라아제 혈증을 보인 급성 Lithium Carbonate 중독증 1례

Lithium carbonate is a widely used and invaluable drug in the treatment and prevention of manic-depressive illness. However, lithium cardonate may induce multisystemic adverse effects and toxic effects that, when not recognized, may lead to severe, life-threatening complications. The authors experienced a manic patient who showed severe lithium toxic reactions with hyperamylasemia. The patient was 41-year-old woman who had received lithium carbonate treatment for 3 months. The patient's symptoms and signs of toxic reaction had disappeared after hydration, insulin therapy, and hemodialysis.

( Hyun Sik Youm ),( Hyun Sik Youm ),( Jong-ryeol Choi ),( Daesik Oh ),( Young Ho Rho ) 대한산부인과학회 2016 대한산부인과학회 학술대회 Vol.102 No.-

목적: To evaluate whether ectopic pregnancy rates differ between natural and hormone replacement endometrial preparation in frozen embryo transfer. 방법: Meta-analysis was performed on the 3 selected studies in the statistical framework R using ‘meta’ package (random effects model: DerSimonian-Laird estimator). The outcome considered in this study was the ectopic pregnancy rates. 결과: The ectopic pregnancy rates were not different between natural and hormone replacement endometrial preparation in frozen embryo transfer (odds ratio [OR] 0.91, 95% confidence interval [CI] 0.40-2.06). 결론: The data presented in this meta-analysis do not support a different risk in ectopic pregnancy between natural and hormone replacement endometrial preparation in frozen embryo transfer.

Modeling of Arrhythmogenic Automaticity Induced by Stretch in Rat Atrial Myocytes

Youm, Jae-Boum,Leem, Chae-Hun,Zhang, Yin Hua,Kim, Na-Ri,Han, Jin,Earm, Yung-E. The Korean Society of Pharmacology 2008 The Korean Journal of Physiology & Pharmacology Vol.12 No.5

Since first discovered in chick skeletal muscles, stretch-activated channels (SACs) have been proposed as a probable mechano-transducer of the mechanical stimulus at the cellular level. Channel properties have been studied in both the single-channel and the whole-cell level. There is growing evidence to indicate that major stretch-induced changes in electrical activity are mediated by activation of these channels. We aimed to investigate the mechanism of stretch-induced automaticity by exploiting a recent mathematical model of rat atrial myocytes which had been established to reproduce cellular activities such as the action potential, $Ca^{2+}$ transients, and contractile force. The incorporation of SACs into the mathematical model, based on experimental results, successfully reproduced the repetitive firing of spontaneous action potentials by stretch. The induced automaticity was composed of two phases. The early phase was driven by increased background conductance of voltage-gated $Na^+$ channel, whereas the later phase was driven by the reverse-mode operation of $Na^+/Ca^{2+}$ exchange current secondary to the accumulation of $Na^+$ and $Ca^{2+}$ through SACs. These results of simulation successfully demonstrate how the SACs can induce automaticity in a single atrial myocyte which may act as a focus to initiate and maintain atrial fibrillation in concert with other arrhythmogenic changes in the heart.

Effects of Taekwondo and Walking Exercises on the Double-Leg Balance Control of Elderly Females

Youm, Chang-Hong,Lee, Joong-Sook,Seo, Kook-Eun Korean Society of Sport Biomechanics 2011 한국운동역학회지 Vol.21 No.2

The purpose of this study was to compare and analyze the effect of twelve-week Taekwondo and walking exercises on the double-leg balance control by dividing elderly females into Taekwondo, walking exercise and control groups. In total, 30 elderly females were randomly divided into Taekwondo, walking exercise, and control groups, with 10 subjects in each group. Subjects participating in this study were 10(age $69.4{\pm}5.8$ years), 10(age $71.4{\pm}7.6$ years) and 10(age $70.6{\pm}4.8$ years) in the three groups, respectively. Although the AP measures were not significantly different among the groups and times, the ML RMS distance and ML velocity, among the ML measures showed a significant difference among the groups and times. Average velocity and 95% confidence ellipse area were also significantly different among the groups and times. Twelve-week Taekwondo and walking exercises were found to be effective in improving static balance control. Future studies on the development of a Taekwondo intervention program tailored for the elderly with many subjects conducted by using a long-term training program are expected.

Youm, Chang-Hong,Shin, Joong-Dal,Lee, Joong-Sook,Seo, Kook-Eun,Park, Jong-Jin Korean Society of Sport Biomechanics 2014 한국운동역학회지 Vol.24 No.2

The purpose of this study was to investigate the effects of localized muscle fatigue and whole body fatigue on postural control during single-leg stance after impairment induced by heel raise and the Harvard step test. Thirty-eight university students (19 men: age, $20.1{\pm}0.2$ yrs; height, $175.0{\pm}5.23cm$; weight, $66.8{\pm}5.6kg$; body mass index, $21.8{\pm}1.7kg/m^2$, 19 women: age, $20.6{\pm}1.1yrs$ ; height, $163.6{\pm}6.7cm$; weight, $58.8{\pm}4.6kg$; body mass index, $22.0{\pm}2.2kg/m^2$) were participated in this study. Subjects performed a series of single-leg postural tasks prior to, following, and 24 hours after completing: heel raise or the Harvard step test. This study showed that the root mean squared distance and velocity in the anteroposterior and mediolateral planes of the center of pressure decreased significantly due to heel raise exercise-induced fatigue. Furthermore, the root mean squared distance in the anteroposterior and mediolateral planes, and the 95% confidence ellipse area of the center of pressure also decreased significantly 24 hours after completing the Harvard step test. In conclusion, this study showed that both heel raise exercise- and Harvard step exercise-induced fatigue affects postural control during single-leg stance in AP and ML planes. Furthermore, this study suggests that changes in the postural control strategy may have occurred after the fatigue protocols during single-leg stance. Also vision can attenuate the postural deficits associated with the fatigues. In order to clarify these results, further studies using other equipment and variables are necessary.
