This study was performed to evaluate the comparison between dietary intake and quality according to stroke prevalence and to determine the association between dietary factors and stroke prevalence using the 5th (2010-2012) Korean National Health and Nutrition Examination Survey (KNHANES) data. The subjects of this study included 6,131 Korean over 50 years old who participated in 5th KNHANES excluding missing data. Health-questionnaires, examination and nutrition survey were conducted by face-to-face interview and measurement. Then, collected data were analyzed for Nutrient Intake (NI), Index of Nutritional Quality (INQ), Nutrient Adequacy Ratio (NAR), Mean Adequacy Ratio (MAR), dietary patterns (DMGFV), Dietary Diversity Score (DDS) and Dietary Variety Score (DVS). All statistical analysis were performed using the SAS (Version 9.3, SAS Institue, Cary, NC). Storke prevalence rate has been showed 3.5% in over 50 years old Korean and male (4.2%) was higher than female (2.9%,p=0.05). According to demographic characteristic, stroke prevalence was higher in high age(p<0.001), less-educated level and low household income group(p<0.05). It was higher in group having medical history of hypertension, diabetes and family history of stroke as well(p<0.001). The anthropometric and biochemical results, female prevalence group showed slightly higher in waist(p=0.003) and body mass index(p=0.04) than normal group. Male and female prevalence group showed high glucose and HbA1c level than normal group(p<0.05). It was observed that stroke prevalence rate showed a relatively higher in case which did not take any dietary supplements(p=0.021) and does not recognize a nutritional label(p<0.001). As a result of nutritional intake, among male prevalence population, it has been showed slightly lower nutritional intake than normal population(p<0.05). In case of female prevalence population, it has been showed lower intake of energy(p=0.004), vitamin C(p=0.037), riboflavin(p=0.008), niacin(p=0.047) than normal group. In INQ results, male prevalence group was lower in intake of protein(p=0.009), vitamin A(p=0.023), riboflavin(p=0.022), calcium(p=0.008) than normal group and female prevalence group was lower in intake of vitamin C(p=0.044) than normal group. Futhermore, in NAR results, male prevalence group was lower in intake of all nutrient than normal group(p<0.05) and female prevalence group was lower in intake of vitamin C(p=0.037), riboflavin(p=0.008), niacin(p=0.047) than normal group. For those reason, MAR was lower in male and female prevalence group than normal group(p<0.05). In dietary patterns, stroke prevalence group has been showed intake deficit of meat, fruit and milk products. Male and female prevalence group was lower in DDS(p<0.01) and DVS(p<0.05) than normal group. In conclusion, stroke prevalence group was lower in nutrient intake and dietary quality than normal group. In addition, logistic analysis suggest that MAR is most relevant dietary factors in stroke prevalence. Stroke is the second leading cause of death in Korea, stroke risk factors has been increasing. According to this study, stroke prevalence was influenced by nutrient intake and dietary quality, therefore dietary and nutritional management is required. Also, individual nutrition education is required for stroke prevention and management.

Physical contact with infants is important because it affects their development. This study would investigate the influences of daily physical contact on the development of two-year-old infant of child care teachers. In particular, this study investigated the impact of natural daily physical contact and playfulness on infants’ problem behavior and relationship between them even if teachers do not plan and implement physical contact play. To investigate the impact of teachers’ perceived daily physical contact with two-year-old infant, playfulness on infants’ problem behaviors on the relationship between these three variables, the research questions were set as follows. Research Question 1. What is the general trend between teacher-infant physical contact, playfulness, and infant problem behavior during daily operation? Research Question 2. Are there significant differences in teacher-infant physical contact, playfulness, and infant problem behavior during daily operation according to the general characteristics of infants and child care teachers? 2-1. Are there significant differences in teacher-infant physical contact, playfulness, and infant problem behavior during daily operations according to infants’ general characteristics? 2-2. Are there significant differences in teacher-infant physical contact, playfulness, and infant problem behavior during daily operations according to child care teachers’ general characteristics? Research Question 3. What is the relationship of teacher-infant physical contact, playfulness, and infant problem behavior during daily operation? Research Question 4. What is the relative influence of teacher-infant physical contact and playfulness on infant problem behavior during daily operation? The data for this study were collected from August 14 to October 6, 2023, from two-year-old classroom daycare teachers working in daycare centers located in five districts and counties in U. Metropolitan City and two-year-old infants. After completing the questionnaires, the researcher personally visited the institution to collect them, and a total of 167 questionnaires were collected, of which 158 were used as the final data, excluding three with responses. This study employed SPSS 29.0 for data analysis. Exploratory factor analysis and reliability analysis for each scale, independent sample t-test, One-Way ANOVA, correlation analysis, hierarchical multiple regression analysis. The results of this study are summarized as follows. First, the general trend of each factor was: Teacher-infant physical contact during daily operation had a mean value above the median, and infant problem behavior was generally low. playfulness was relatively high compared to the other variables. Second, there were differences between physical contact, infant problem behavior, and playfulness based on the daycare teachers’ general characteristics. Third, the researcher examined the correlations between teacher-infant physical contact, infant problem behavior, and playfulness, and found partial significant correlations among the sub-variables. Fourth, the researcher examined the relative effects of teacher-infant physical contact and infant playfulness on infant problem behavior, the emotional situation a sub-variable of physical contact between teacher and infant and physical spontaneity a sub-variable of playfulness, had a significant positive impact on infant problem behavior, while social spontaneity a sub-variable of playfulness had a significant negative impact on infant problem behavior. The above findings confirm the importance of teacher-infant physical contact during daily operation in daycare centers and suggest that further research on the influence of physical contact in daily life is needed. Therefore, hopefully, the results of this study will be utilized as baseline data for promoting physical contact appropriate to the development and characteristics of infants in childcare institutions. 영아의 신체접촉은 발달에 영향을 미치기 때문에 중요하다. 이에 본 연구에서는 2세 영아의 어린이집 하루일과에서의 신체접촉과 놀이성이 가지는 영향력을 알아보고자 하였다. 특히, 교사가 신체접촉놀이를 계획, 실행하지 않더라도 일과 내 자연스러운 신체접촉과 놀이성이 영아 문제행동에 미치는 영향과 관계를 알아보는 것을 목적으로 하였다. 본 연구의 일과 운영 중 2세 영아와의 신체접촉과 놀이성이 영아 문제행동에 미치는 영향력을 살펴보기 위해 다음과 같이 연구 문제를 설정하였다. 연구문제 1. 일과 운영 중 교사-영아의 신체접촉과 놀이성, 영아 문제행동 간의 일반적인 경향은 어떠한가? 연구문제 2. 영아와 보육교사의 일반적 특성에 따라 일과 운영 중 교사-영아의 신체 접촉, 놀이성, 영아 문제행동에는 유의한 차이가 있는가? 2-1. 영아의 일반적인 특성에 따라 일과 운영 중 교사-영아의 신체접촉, 놀 이성, 영아 문제행동에는 유의한 차이가 있는가? 2-2. 보육교사의 일반적인 특성에 따라 일과 운영 중 교사-영아의 신체접촉, 놀이성, 영아 문제행동에는 유의한 차이가 있는가? 연구문제 3. 일과 운영 중 교사-영아의 신체접촉, 놀이성, 영아 문제행동은 유의한 상관이 있는가? 연구문제 4. 일과 운영 중 교사-영아의 신체접촉과 영아 놀이성이 영아 문제행동에 미치는 상대적 영향력은 어떠한가? 본 연구는 U광역시에 5개 구군에 소재한 어린이집에 근무하고 있는 2세반 보육교사 와 2세 영아를 대상으로 2023년 8월 14일부터 10월 6일까지 자료를 수집하였다. 설문 완료 후에는 연구자가 직접 기관에 재방문하여 수거하였으며, 회수한 설문지는 총 167부로, 이 중 응답이 불성실한 9부를 제외한 158부를 최종 자료로 사용하였다. 본 연구는 자료 분석은 SPSS 29.0 프로그램을 활용하였으며, 각 척도에 대한 탐색 적 요인분석과 신뢰도 분석, 독립표본 t-검정, 일원배치 분산분석, 상관분석, 다중회귀 분석을 실시하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 각 요인의 일반적인 경향은 일과 운 영 중 교사-영아 간의 신체접촉은 중간값 이상의 평균값이 나타났으며, 놀이성은 다 른 변인들에 비해 비교적 높게 나타났다. 영아의 문제행동의 경우 전반적으로 낮게 나타났다. 둘째, 일과 운영 중 교사-영아의 신체접촉, 놀이성, 영아 문제행동은 일반적 인 특성인 어린이집 유형, 보육교사 연령, 결혼 여부, 최종학력, 영아반 보육경력, 자격 증 유형, 자격증 취득경로, 전공에 따라 부분적으로 유의한 차이를 나타냈다. 셋째, 일 과 운영 중 교사-영아의 신체접촉, 놀이성, 영아 문제행동 간의 상관관계를 살펴본 결 과, 하위변인 간에 부분적으로 유의한 상관관계가 있는 것으로 나타났다. 넷째, 영아 문제행동에 대한 교사 변인, 교사-영아 간의 신체접촉과 놀이성의 상대적 영향력 살 펴본 결과, 교사-영아의 신체접촉 하위변인인 정서 상황과 놀이성의 하위변인인 신체 적 자발성은 유의한 정적 영향, 놀이성의 하위변인인 사회적 자발성은 부적 영향력을 갖는 것으로 나타났다. 이상의 연구 결과를 통해 어린이집에서 일과 운영 중 보육교사와 영아의 신체접촉 중요성을 확인하였으며, 일과 운영 중 신체접촉의 영향력에 관한 후속 연구가 지속적 으로 필요함을 시사한다. 그러므로 본 연구 결과가 보육기관에서 영아의 발달, 특성에 따라 적절한 신체접촉을 증진하는 기초자료로 활용되기를 기대한다.
