저자들은 비교적 희귀한 자궁 내막에 발생하는 clear cell선종을 30세의 월경 연령에서 발견하였기에 간단한 문헌고찰과 함께 보고하는 바이다. Clear cell adenocarcinoma of the endometrium, an infrequent variant sharing a common M滸lerian origin, accounts for a few percent of all endometrial cancers. These tumors occur predominantly in postmenopausal women and carry a relatively unfavorable prognosis. But, we experienced a case of clear cell adenocarcinoma of endometrium in menstrual woman. This paper presents this case and a brief review of the literatures.

유정옥,김정순 한국지역사회간호학회 2015 지역사회간호학회지 Vol.26 No.2

Purpose: To explore the association between sleep and the risk of accidental injury at school among Korean adolescents. Methods: From the database of the Ninth Korea Youth Risk Behavior Web-based Survey (KYRBS), the researcher selected 63,307 adolescents who responded to a survey on sleep hours. We conducted logistic regression with sleep duration and fatigue after sleep as independent variables, the risk of injury at school as a dependent variable, and gender, grade, school type, economic status, parents’ education level, number of participations in physical education, and current smoking and drinking as control variables. Results: Using 9 hours of sleep as the reference, the adjusted injury risk (odds ratio) was 1.74 for those sleeping less than 5 hours a day, 1.61 for 5 hours, 1.45 for 6 hours, 1.31 for 7 hours, 1.13 for 8 hours, and 1.40 for 10 hours or longer. The difference between each pair of groups was statistically significant. In this study, injury risk increased as sleep duration decreased and fatigue after sleep increased. Conclusion: The findings suggest that a short nightly duration of sleep and fatigue after sleep can be considered potential risk factorsfor unintentional injuries at school among Korean adolescents.

Purpose: This study aimed to investigate mothers’ questions related to parenting young children in the internet community. Methods: One representative in the internet community was selected and parenting questions were collected over 2 weeks in October 2019. A total of 15,016 questions were analyzed by frequency and proportion after categorizing of 10 themes; health and daily care, connecting and communicating, play and learning, development and growth, poos and wees, sleep, feeding, solid foods, safety, behavior. Results: The most frequently asked questions per age ranged from 1 to 3 months (32.2%). The most frequently asked questions by theme per age were about feeding newborn up to 6 months, solid foods from 7 to 12 months, health and daily care from 13 to 24 months, and play and learning from 25 to 71 months. Conclusion: As these results reflect mother’s need for information and support, it is suggested that more specific and targeted online/offline support per age should be developed.

Purpose: This study was aimed to evaluate the effect of an internet community on knowledge, self-efficacy, and self-care behavior in workers with hypertension. Method: The research design used was a nonequivalent control group pre-test and post-test design. Sixty hypertensive workers participated in this study(Exp.=29, Cont.=31). The data was collected from the 3rd of November 2003 to the 27th of February 2004 using an interview with questionnaires. Information related to hypertension was provided on the internet community weekly and an e-mail newsletter was sent in order to increase participation in the internet community. We used a tool developed by Park Young-Im(1994) that measured knowledge related to hypertension and self-efficacy. A tool developed by Jung Mi-Young(2001) was used for self-care behavior. The collected data was analyzed with an χ2-test and t-test using the SPSS WIN 10.0 program. Result: The internet community helped workers with hypertension to increase their knowledge related to hypertension, as well as increasing their self-efficacy and self-care behavior. Conclusion: An internet community could be applied as hypertensive nursing intervention.

To determine the reason of individual variation of the effect of caffeine. the absorption and the disposition of caffeine were studied in caffeine sensitive and caffeine nonsensitive volunteers. And also to study the effect of obesity on caffeine pharmacokinetics, the caffeine disposition in the obese rat and in the lean rat were investigated respectively. In result the caffeine sensitive group showed a longer terminal half-life of caffeine(7.35±0.71 hr:5.49±0.73 hr) and a larger AUC (55.42±9.09㎍·㎖^-1·hr:440.0±7.81㎍·㎖^-1·hr) than that of caffeine non-sensitive group without statistical significance. The obese rat showed a longer terminal half-life (3.47hr : 2.31hr) and a larger AUC(35.3㎍·㎖^-1·hr:26.97㎍·㎖^-1·hr) than that of the lean rat. But there was no correlation in the amount of daily caffeine consumption and obesity. In conculusion, we suggest that the individual variation of the effect of caffeine are being caused from the individual differances of caffeine susceptibility or tolerance rather than the differances of the genetic metabolic capacity or metabolic tolerance.

다수준 분석을 이용한 청소년의 학교 내 손상 관련 요인

유정옥,김묘성 한국지역사회간호학회 2016 지역사회간호학회지 Vol.27 No.4

Purpose: This study aims at identifying individual- and school-level factors associated with unintentional injuries to Korean adolescents at school by applying multilevel modeling. Methods: From the database of the eleventh Korea Youth Risk Behavior Web-based Survey (KYRBS), the researchers selected 68,043 adolescents from the 7th to the 12th grades. Data were analyzed using x2 test for prevalence and multilevel modeling for related factors of unintentional injuries at school. Results: About 22.9 percent of the adolescents had treatment experiences for unintentional injuries at school in the past 12 months. At the individual level, the significant factors associated with unintentional injuries at school included gender, grade, academic achievement, current smoking, alcohol consumption, frequency of high caffeine intake, depression, and relief of fatigue after sleep. At the group level, the significant factors included number of physical education per week and safety education. Conclusion: School based injury prevention programs should be sensitive to both individual- and school-level factors associated with unintentional injury at school among Korean adolescents.

청소년이 지각한 부모의 심리적 통제가 자기효능감을 매개로 학습된 무기력에 미치는 영향

유정옥,정문경 한국청소년학회 2016 청소년학연구 Vol.23 No.10

The aim of this study is to identify the effects of parental psychological control as perceived by adolescents on their learned helplessness with self-efficacy as a mediator. . For this, in this study, the regression analysis suggested by Baron & Kenny (1986) was conducted on the data collected from 343 male and female middle and high school students living in Gyeonggi-do, using SPSS 18.0. The study produced the following results: first, the study found a positive correlation between parental psychological control and adolescents’ learned helplessness, and a negative correlation between self-efficacy and learned helplessness. Second, parental psychological control had an impact on learned helplessness with self-efficacy as a partial mediator. It means that by giving psychological autonomy and adopting a reasonable attitude towards children, parents can help improve their adolescent children’s self-efficacy and ultimately prevent them from developing learned helplessness. In addition, the implications of the study on the basis of these results and the limitations and future research directions are discussed. 본 연구는 청소년이 지각한 부모의 심리적 통제와 청소년의 학습된 무기력간의 관계에서 자기효능감이 어떠한 요인으로 작용하는지를 규명하고자 이루어졌다. 이를 위하여 청소년이 지각한 부모의 심리적 통제가 자기효능감을 매개로 청소년의 학습된 무기력에 영향을 미치는지를 분석하였다. 이를 위해 총 400명의 남녀공학 중·고등학교 학생들에게 부모의 심리적 통제척도, 자기효능감 척도, 학습된 무기력 척도로 구성된 설문지를 실시하였고, 이를 통해 수집된 343명의 자료에 대하여 상관분석과 회귀분석을 실시하였다. 분석 결과 첫째, 부모의 심리적 통제와 자기효능감, 부모의 심리적 통제와 학습된 무기력, 자기효능감과 학습된 무기력간에 상관관계가 있는 것으로 나타났다. 둘째, 부모의 심리적 통제는 자기효능감을 부분매개로 학습된 무기력에 영향을 주는 것으로 나타났다. 이는 청소년들이 부모의 심리적 통제가 높다고 지각하면 자기효능감이 낮아지고 이를 매개로 학습된 무기력이 나타날 수 있음을 시사한다. 이러한 결과를 바탕으로 본 연구의 시사점과 제한점 및 추후 연구를 위한 제언을 하였다.
