신뢰도 연구는 한 명의 평가자가 연구 대상을 반복 측정하거나 여러 명의 평가자가 한 대상을 평가할 때 평가자 내, 평가자 간 일치도를 알아보는 연구로 임상 의학 분야에서 빈번하게 쓰이고 있다. 이 같은 신뢰도 연구에서 적절한 표본수, 평가자수 및 반복수를 결정하는 것은 비용과 시간 측면에서 보다 더 효율적인 연구를 할 수 있게 해주는 중요한 요인이다. 본 연구의 목적은 신뢰도 연구에서 측정치가 정량적일 때 쓰이는 신뢰도 계수인 급내상관계수(ICC)와 관련한 기존의 표본수 산출 방법들을 비교분석하여 적절한 표본수나 반복수를 결정할 때 그 지침을 제공하는데 있다. 기존 논문에서 제시한 Walter 등 (1998), Giraudeau와 Mary (2001), Saito 등 (2006) 그리고 Bonett (2002)의 방법들을 비교하였다. 임의효과 일원배치 모형일 때 같은 조건에서 가장 적은 양의 정보를 필요로 하는 방법을 찾는 목적으로 요인을 변화시켜 가면서 표본수, 반복수, 신뢰구간 폭을 비교한다. 비교해 본 결과, 가장 작은 수의 표본을 필요로 하는 방법은 Giraudeau의 방법, 가장 작은 수의 반복을 필요로 하는 방법은 Saito의 방법으로 나타났다. 가장 많은 수의 표본과 반복을 필요로 한 방법은 Bonett의 방법이었다. 정도는 Giraudeau의 방법이 가장 높았고 Walter, Saito, Bonett 순으로 정도가 떨어졌다. In medical practice and research, the problem of assessing reliability between two or more quantitative measures is quite common. Intraclass correlation coefficient(ICC) is commonly used to scale of reliability. Some methods were developed to calculate the required number of subjects, raters or replicates in one-way or two-way random ANOVA models. This paper, studies and compares the performance of four methods such as Walter et al. (1998), Giraudeau and Mary (2001), Saito et al. (2006) and Bonett (2002). In order to compare the efficiency of methods we compare the number of subjects, replicates and the width of confidence interval of ICC needed for some specific ICC values. In the case of subject size, Giraudeau's method is the best. In case of the number of replicates, Saito's method was superior to others. The width of confidence interval of ICC was narrower for Giraudeau's method than any others.

Purpose: To investigate factors that may affect the method of feeding among preterm infants at 4 weeks after discharge. Methods: This study included 222 mother-infant dyads born before a gestational age of 37 weeks. The feeding method and general medical characteristics of the participants were assessed at 4 weeks after discharge using a structured questionnaire. Multinomial logistic regression analysis was used to examine which factors were associated with breastfeeding at home. Results: Of the 222 infants who qualified for the study, 71 (32.9%) continued to receive breastmilk at 4 weeks post-discharge. Multinomial logistic regression analysis showed that breastfeeding at 4 weeks post-discharge was associated with higher breastfeeding self-efficacy, vaginal delivery (experience), direct breastfeeding in the neonatal intensive care unit (NICU), gestational age between 30 and 34 weeks, and breastmilk consumption in the NICU. The following factors were associated with mixed feeding at 4 weeks post-discharge: being employed, having higher breastfeeding self-efficacy, and direct breastfeeding in the NICU. Conclusion: NICU nurses should provide opportunities for direct breastfeeding during hospitalization and support breastfeeding to enhance breastfeeding self-efficacy. These factors may help to ensure the continuation of breastfeeding after discharge. Moreover, factors that affect breastfeeding should be considered when providing interventions.

The objective of this study is to propose a Korean medical rehabilitation protocol for total knee replacement (TKR) and to report its effectiveness. This study was conducted as a retrospective study which analyzes the medical records of 4 patients undergoing Korean medical rehabilitation with protocol and continuous passive motion exercise for more than two weeks after TKR. We evaluated the outcome checking physical examination findings of the knee joint, numeric rating scale (NRS), Lysholm knee score (LKS) and walking state. After the treatment, we observed that the function of knee joint, NRS, LKS, walking state of patients were improved. This study showed that Korean medical rehabilitation protocol has effect on knee joint recovery after TKR. The limitation of this study was the insufficient number of cases and short-term follow up. Further studies should be done steadily to report the effectiveness of a Korean Medical rehabilitation protocol for TKR. (J Korean Med Rehabil 2020;30(4):219-231)

Purpose: Traffic accidents are the major cause of death in children. Car seat usage in children is important to reduce the risk of death or injury caused by traffic accidents. This study aims to analyze the trends of car seat use among children ages under 6. Methods: This study adopted a cross-sectional study utilizing the Korea National Health and Nutrition Examination Survey from 2015 to 2019. In total, 1,999 responses were included for the analysis. Factors associated with car seat use were age, sex, body weight, height, family type, household income, and monthly household income. Regression analysis was used to compare the car seat use before and after the revision of the Road Traffic Act (2015∼2018 vs. 2019). Results: We found that car seat use was increasing by year, age, region, and household income. Car seat use was higher after fines increased in 2019. Age and body weight had negative association with car seat use, while height and household income had positive association with car seat use. Conclusion: Car seat use increased from 2015 to 2019 and is associated with different ages among children and household income. Further education and promotion that describes the safety benefits to children from car seat use are needed.

The present study purposed to survey the state of environmental education using school forests and to examine the effects of school forests on elementary students` environmental consciousness and attitude, and ultimately to provide basic materials for making plans to utilize school forests in environmental education. According to the results of this study, the frequency of environmental education, the use of school landscape in environmental education, etc. in elementary school were low, and a main reason for that was that current environmental education was executed mostly through lecture-based classes. Elementary students` environmental consciousness was found to be significantly correlated with the number of flowerpots at home. This suggests that students` environmental consciousness can be developed naturally while they contact and raise plants by themselves.

Cancer of the vulva accounts for approximately 0.5% of all gynecologic malignancies. At diagnosis, one-third of these cases is detected in an advanced stage (FIGO stages III, IV), and local extension of primary vulvar cancer may involve adjacent midline structures such as the clitoris, urethra, vagina, and anus. Initial surgical therapy of such locally advanced primary cancers may compromise the functional integrity of midline structures, necessitating ultraradical surgery including pelvic exenteration. In view of the relatively elderly age of the patients and the morbidity of this ultraradical dissection, concomitant chemoradiation therapy - that the efficacy had been proven in head and neck cancer, anal cancer has approached for patients with locally advanced vulvar cancer. We experienced a case of stage III vulvar cancer patient, who underwent concomitant chemoradiation therapy with 5-fluorouracil(FU) and cisplatin and who showed complete response. So, we report this case with brief review of the literatures.

본 연구는 시간의 흐름에 따른 유아의 놀이방해 행동 변화양상을 살펴보고, 교사-유아 간 상호작용이 유아의 놀이방해 행동에 미치는 영향력을 분석하고자 하였다. 나아가 유아의 성별이나 미디어사용 시기, 어머니의 교육수준, 직업 유무, 통제적 양육태도 등이 놀이방해 행동에 미치는 영향력을 검증하고자 하였다. 이를 위해 육아정책연구소의 한국아동패널(PSKC) 5차년도(5세)에서 7차년도(7세)까지 3년간의 종단자료(총 2,150명: 남-1,091명, 여-1,059명)를 사용하여 잠재성장모형 분석을 실시하였다. 주요 연구결과는 첫째, 유아의 놀이방해 행동은 5세에서 7세로 시간이 변하면서 다소 감소하는 양상을 보였다. 둘째, 교사-유아 간 상호작용이 놀이방해 행동에 미치는 영향은 동시효과와 지연효과가 있는 것으로 나타났다. 셋째, 유아 놀이방해 행동의 개인적 차이의 초기값은 성별, 미디어사용 시기, 어머니 직업 유무, 교육수준의 영향을 받고, 변화율은 유아의 미디어사용 시기와 어머니의 통제적 양육태도의 영향을 받는 것으로 확인되었다. 주요 연구결과를 토대로 유아의 부적응적 상호작용인 놀이방해 행동 감소를 위한 교사와 어머니의 역할을 논의하고 시사점을 제시하였다. This study explores the changes in young children’s play disrupting behaviors and examines the effects of teacher-child interaction on play disrupting behaviors. In addition, the study explores how young child’s play disrupting behaviors would be affected by his or her gender and age of first media use as well as by maternal education level, occupational status, and controlling parenting attitude. For those purposes, this study analyzed the fifth- through seventh-year longitudinal data (ages 5 to 7) from the Panel Study of Korean Children (PSKC) using the latent growth model. Main results are as follows. First, the slight decreasing tendency was found from age 5 to age 7 in young children’s play disrupting behaviors. Second, there were significant concurrent and lagged effects of teacher-child interaction on young children’s play disrupting behaviors. Third, the initial differences in young children’s play disrupting behaviors were affected by their gender, their age of first media use, and their mothers’ occupational status and education level, while the differences in the growth rate of play disrupting behaviors were affected by the children’s age of first media use and their mothers’ controlling parenting attitude. Based on those results, the study provides the implications about teachers’ and mothers’ roles in reducing young children’s maladaptive play disrupting behaviors.

Objectives: The purpose of this study was to survey Korean solders` oral healthcare recognition and perceived oral health concern. Methods: The data was collected from a questionnaire given 157 soldiers in Chungcheongnamdo. The data was analyzed into t-test, one-way ANOVA and Pearson`s correlation analysis. Results: 25.5% replied that they were concerned about oral health. Soldiers who have received oral healthcare education exhibited higher recognition on the prevention of dental caries and periodontal disease. Moreover, those who have used oral hygiene devices also showed higher recognition on the prevention of dental caries and periodontal disease. The recognition of preventive effects on dental caries, in particular, showed a statistically significant difference (p<0.05). In regard to the relationship between oral health concern and recognition of oral healthcare, those who were more concerned about oral health were higher recognition of periodontal disease prevention(r=0.254, p<0.01). Conclusions: To improve concern and recognition of oral health for the members, the soldiers needs to develop oral health education and policy.
