        운동유발성 근육상해 후 IASTM 처치가 회복기 섬유화 반응에 미치는 영향

        백경아,김종오 한국체육과학회 2023 한국체육과학회지 Vol.32 No.2

        The purpose of this study is to investigate the effect of applying instrument-assisted soft tissue mobilization (IASTM) to muscle fibrosis due to motor-induced muscle damage. 24 male students participated in this study, and were randomly assigned to the IASTM group and the control group, respectively. For the IASTM group, IASTM was applied to muscles such as rectal femur muscles 48 hours after exercise. Maximum strength (leg extension and leg refraction), TGF-γ, CK, LDH, TNF-,, and IL-6 were measured as variables, and repeated measurement variance analysis was used for statistical analysis. As a result of the study, there was: Significant interaction effects of time and groups on maximum strength (leg dilatation and leg flexion), TGF-γ, CK, LDH, TNF-및, and IL-6 and IASTM groups showed more improvements in recovery at maximum strength (leg dilatation and leg flexion), TGF-γ, CK, LDH, TNF-α, and IL-6. In conclusion, the application of IASTM to male students showed that it was effective in improving muscle fibrosis due to muscle damage caused by exercise.

        불법원인급여반환금지규정의 적용제한에 관한 비판적 고찰

        백경일(Paek, Kyoung-Il)(白慶一) 한국재산법학회 2012 재산법연구 Vol.29 No.4

        불법원인급여에 관하여 우리 민법은 제746조에 반환금지의 규정을 두고 있지만, 그로 인해 불법원인급여관계에서 선급부자가 불이익을 당하는 불공평이 발생하여, 그동안 많은 법학자들이 이를 극복하기 위한 이론을 개발한 바 있다. 혹자는 불법개념을 축소함으로써 불법원인급여의 적용범위를 좁히려 하였고, 혹자는 제746조의 단서규정을 확대하여 폭넓은 예외를 인정하려 하였으며, 혹자는 일반예방과 비례성의 원칙에 따라 법관이 재량껏 적용여부를 판단하게끔 하자고 주장한 바 있으나, 이러한 기존의 이론들은 모두 우리 민법 제746조의 문리적 해석에서 지나치게 벗어난 것들로서 법적 안정성이라는 측면에서 심각한 문제점을 노출하는 데 예외가 없었다. 본고는 이러한 기존의 이론들을 대신하여 독일의 통설이 주장하는 바와 같이 각 금지규범의 목적에 따라 민법 제746조의 적용여부를 판단하자는 대안을 제시하였으며, 그 밖에 급부개념을 엄격해석한다든지 사무관리나 불법행위의 규정을 적용하는 등의 이론을 소개하여 민법 제746조의 역기능 극복에 관하여 새로운 가능성을 모색하고자 하였다. In Korea normiert eine Kondiktionssperre § 746 KBGB, welcher lautet: "Wird ein Vermögen oder ein Dienst aus einem unrechtlichen Grund geleistet, so ist die Rückforderung ausgeschlossen. Dies gilt jedoch nicht, wenn ein solcher Grund nur beim Empfänger vorliegt." Nach dieser Vorschrift bleibt dem Leistenden ein Bereicherungsanspruch versagt, falls ihm seinerseits ein Verstoß gegen ein gesetzliches Verbot oder gegen die guten Sitten zur Last gelegt werden kann. Aber die Funktion dieser, historisch überkommener Regelungen sind seit langem überaus zweifelhaft und streitig: Denn der Vorleistende kann schon keine Erfüllung verlangen. Wenn man ihm nun selbst die Rückforderung des Geleisteten verwehrt, zieht der Empfänger aus dem nichtigen Vertrag einen ungerechtfertigten Vorteil. Deswegen ist in der koreanischen Literatur und Rechtsprechung schon lange versucht worden, § 746 KBGB auf jene Fälle nicht anzuwenden, in denen der Leistende gegen zwingende Bestimmung etwas hingibt, was aber nicht sittenwidrig ist. Denn nicht alle zwingenden Bestimmungen beziehen auf die guten Sitten. Übrigens versucht die sog. Unrechtsvergleichstheorie, die Anwendung des § 746 KBGB auf die Fälle einzuschränken, in denen der Leistende vergleichsweise mehr Unrecht begeht als der Empfänger. Bei der Reduktion des § 746 BGB und der Unrechtsvergleichstheorie bleibt jedoch zu viel Raum für richterliche Willkür. Schon der Tatbestand der Sittenwidrigkeit ist offen und lässt einem Richter viel Spielraum, das gilt für die im Rahmen der Vergleichung des Unrechts noch viel mehr. Das ändert sich auch nicht, wenn die Unrechtsvergleichstheorie mit dem Generalpräventionsgedanke und dem Verhältnismäßigkeitsprinzip ergänzt wird. Denn damit im Rahmen der Rechtfertigung zu treffenden Abwägung, wird die Gefahr der Beliebigkeit noch erhöht. Deshalb schlägt dieser Aufsatz vor, die Einschränkungen des Anwendungsbereichs des § 746 KBGB präzis auf den Schutzzweck der verletzten Norm zurückzuführen und den Begriff der Leistung genauer zu definieren. Für die Geschäftsführung ohne Auftrag und unerlaubte Handlungen wird andererseits die entsprechende Anwendung des § 746 KBGB nicht anzuerkennen, weil sich § 746 KBGB als eng auszulegende Ausnahmebestimmung einer Ausdehnung auf Ansprüche außerhalb des Bereicherungsrechts entzieht. Dadurch kann das Problem der Funktionsstörung des § 746 KBGB teilweise überwunden und gleichzeitig der Gefahr richterlicher Willkür vorgebeugt und Rechtssicherheit geschafft werden.

        Association between Quality of Life and Menstrual Irregularity among Pre-menopausal Women

        백경아,박선아 한국웰니스학회 2018 한국웰니스학회지 Vol.13 No.1

        Menstrual irregularity has a negative impact on not only the physical and mental health of affected women, but also on the activities of academic and daily life. This study used a secondary analysis of data from the 5th Korean National Health and Nutrition Examination Survey (2010-2012) with 4,776 pre-menopausal Korean women to examine the relationship between menstrual irregularity and quality of life. The EuroQol five-dimension scale (EQ-5D) was used to measure the quality of life. Data were analyzed using χ2-test and hierarchical multivariate logistic regression analysis. The result is as following. First, menstrual irregularity is significantly associated with the increased risk of lower quality of life, specifically mobility OR=1.52, 95% CI=1.03-2.25), self-care (OR=2.97, 95% CI=0.97-9.07), usual activities (OR=2.74, 95% CI=1.65-4.55), pain/discomfort (OR=173, 95% CI=1.38-2.16), and anxiety/depression (OR=1.68, 95% CI=1.30-2.19) of all dimensions of the EQ-5D. Second, the prevalence of the menstrual irregularity tended to increase, as the number of problem EQ-5D domains increased (p < .001). This study suggests that initial assessment and management of menstrual irregularity should be addressed in the women’s health care.

        고등학생의 자녀출산에 대한 주관성

        백경아,권혜진,유승희 여성건강간호학회 2013 여성건강간호학회지 Vol.19 No.1

        This study was to explore subjectivity on childbearing in high school students. Methods: A Q-methodology which provides a method of analyzing the subjectivity of each type was used. Forty-three high school students classi-fied 40 selected Q-statements into 9 points standard. The obtained data were analyzed into two types: Type 1 turned out to be" FOLS(family oriented life style)"and Type 2"CINK(couple important no kid)". Conclusion: In order to resolve such problems as low birth rate and the advanced age of the population, effective youth and adult programs, policy and institution are required. The current demographic, economic and other factors such as personal values and poli-cies may lower birth rate. In particular, youths' need for children and birth rate tend to be lower. There are positive and negative pattems in high school students' subjectivity on childbearing. Thus, national and social efforts are need-ed to change negative factors into positive ones. In order to maintain positive subjectivity on childbearing in high school students, it is necessary to apply family-centered educational programs and to implement birth-friendly and realistic programs for promoting child birth.

        Effects of Swimming Exercise and Nicotine Injection during Pregnancy on Spatial Memory Function and Synaptic Plasticity Neurotrophic Factor in the Hippocampus of Rat Pups

        백경아,윤진환,이희혁,김종오 한국생활환경학회 2016 한국생활환경학회지 Vol.23 No.4

        In the present study, we attempted to determine the effects of maternal swimming exercise and nicotine injection during pregnancy on spatial learning memory ability and synaptic plasticity neurotrophic factor in hippocampal in rat offspring. After confirming pregnancy, the pregnant rats were divided into four groups (n = 6 in each group): the control group (CG), the swimming group (EG), the nicotine-treated group (NCG), and the swimming and nicotine-treated group (NEG). The experimental animals received 1mg nicotine/kg maternal body weight/day during gestation and lactation (G&L). Beginning on the 7 day of pregnancy, the pregnant rats in the swimming group were forced to swim on a pool for 30 min at a mild-intensity, once a day until delivery. After all the pregnant rats had given birth, there were rat pups available for use in this study in each group (n = 12 in each group). Here in this study, we have shown that both synaptic-plasticity neurotrophic factor expression and PSD were suppressed in nicotine-treated rats, whereas swimming exercise alleviated the nicotine-induced suppression of both synaptic-plasticity neurotrophic factor expression and PSD in the hippocampus of rats. The results of the present study indicate that swimming exercise may facilitate recovery from the CNS complications associated with smoking by inducing enhanced the morphological development of synapses in the hippocampus via the augmentation of synaptic-plasticity neurotrophic factor expression in the hippocampus.

        저항성 운동이 당뇨 쥐 고환 조직의 Catsper-1, GLUT-8 발현 및 염증지표에 미치는 영향

        백경아,윤진환 한국생활환경학회 2018 한국생활환경학회지 Vol.25 No.6

        Diabetes is associated with impairment of male reproduction ability. This study aims to investigate the effects of resistance exercise training on expression of CatSper-1, GLUT-8 protein in testis and blood inflammatory markers in diabetic rats. At 24 weeks of age, OLETF and LETO rats(N=30) were randomly assigned to a control group(CON, n=10), diabetes group(DM, n=10) and diabetes and resistance exercise group(DM+EXE, n=10). The DM+EXE group was trained progressively on a ladder climbing, 3 days per weeks for 12 weeks. In the testis, CatSper-1 and GLUT- 8 protein expression were significantly increased in DM+EXE group compared with DM group(p<.05). Serum IL-6 and TNF-α were significantly decreased in DM+EXE group compared to DM group, whereas IL-10 was significantly increased in DM+EXE group. And HOMA-IR index also was significantly lower in DM+EXE group than DM group(p<.05). These results showed that 12 weeks resistance exercise training can improve male reproductive function in diabetes conditions.
