권정현,권용준 한국초등상담교육학회 2024 초등상담연구 Vol.23 No.4
This study selected life stress, social relationship anxiety, and positive psychological capital as variables related to school adaptation of elementary school students who moved to an urban housing development district and attempted to verify their levels and influence. For this purpose, a total of 332 data from 4th to 6th grade elementary school students in Region C who relocated in 2023 were used in the final analysis. The main research results are summarized as follows. First, as a result of analyzing differences between groups according to gender and grade for each research variable, there were differences in social relationship anxiety and school adaptation depending on gender, and differences in life stress, positive psychological capital, and school adaptation depending on grade. Second, gender, grade, life stress, and positive psychological capital were found to have an effect on the study subjects' school adaptation. However, the influence of social relationship anxiety was not significant. Third, the factors affecting the study subjects' school adaptation were found to differ depending on gender and grade. The results of this study are significant in that they are the first approach to the factors related to school adaptation of elementary school students before elementary schools in urban areas. Based on this, major implications and follow-up research were proposed in relation to elementary school students' school adaptation following the relocation of elementary schools to urban areas, which will continue to occur due to future population decline and urban development.

This study aimed to confirm that the lateral lines of fish indicate water temperature, water pressure, water flow, and sound waves by conducting a direct experiment. To confirm the superiority of fish lateral lines to detect material stimuli after the experimental study of the fish lateral line's sensation function, the lateral line's tissue was expanded and the shape of the lateral side of the fish was created using a 3-D printer to realize the lateral stripe parity. The amplification effect was confirmed by measuring the sound waves, which was the material stimulus of the lateral diagonal parabola. This proved that fish lateral lines are biotechnologically superior sensory organs.

권정현,김현진,홍영미 대한소아청소년과학회 2005 Clinical and Experimental Pediatrics (CEP) Vol.48 No.11
Purpose : Childhood Obesity is increasing throughout the world, and it is known to incur many diseases especially in later life such as diabetes and cardiovascular disorders. The purpose of this study was to investigate the association between obesity and insulin, insulin-like growth factor-I (IGF-I), insulin-like growth factor binding protein-3(IGFBP-3) and know if these factors are useful in predicting cardiovascular diseases. Methods : The study group consisted of 64 moderate and severe obese adolescents and the controls were normal adolescents of the same age. body mass index(BMI) was calculated by height and weight; systolic and diastolic blood pressure was measured at resting state. After 10-hour fasting period, blood cholesterol, triglyceride, high density lipoprotein(HDL) cholesterol, low density lipoprotein(LDL) cholesterol, glucose, insulin, free fatty acid, IGF-I and IGFBP-3 were measured. Results : Insulin was significantly higher in the obese adolescent group than the control group(obese group 15.6±7.0 µIU/mL, P<0.01). IGF-I was also significantly higher in the obese adolescent group than the control group(obese group 498.1±122.2 ng/mL, P<0.05). In addition, IGFBP-3 was significantly higher in the obese adolescent group than the control group(obese group 3,777±4,721 ng/mL, P<0.05). Insulin showed significantly positive correlation with BMI(r=0.3944) and obesity index(r= 0.34). IGFBP-3 were significantly correlated with obesity index(r=0.419), diastolic blood pressure (r=0.264) and BMI(r=0.247). Insulin resistance index significantly positive correlation with BMI(r= 0.595), blood triglycerid level(r=0.515) and obesity index(r=0.469). Conclusion : Serum insulin, insulin resistance index, IGF-I and IGFBP-3 levels may be useful to predict cardiovascular diseases in adolescent obesity. 목 적 : 소아 비만은 전세계적으로 증가하고 있는 추세이며, 신체적으로나 정신적으로 장애를 일으킨다. 특히 고혈압, 관상동맥질환, 당뇨병 등의 성인병이 문제가 되고 있다. 이에 비만 청소년에서 혈중 인슐린, 인슐린저항지수, 유리 지방산, IGF-I, IGFBP-3를 측정하였고, 심혈관 질환으로 진행할 수 있는 위험 인자로 유용한지 알아보기 위해 본 연구를 실시하였다.방 법 : 64명의 중등도 이상의 비만 청소년를 대상군으로 하였고, 같은 연령의 정상 청소년 20명을 대조군으로 하였다. 신장, 체중을 이용하여 비만도와 체질량지수를 산출하였고, 안정된 상태에서 수축기, 이완기 혈압을 측정하였다. 10시간 이상 금식 후 총 콜레스테롤, 중성지방, HDL 콜레스테롤, LDL 콜레스테롤, AST, ALT, 혈당, 인슐린, 유리지방산, IGF-I, IGFBP-3를 측정하였다. 결 과 : 인슐린은 비만군에서 15.6±7.0 IU/mL로 정상군보다 유의하게 높았고(P<0.01), 인슐린저항지수도 비만군에서 64.6±31.6으로 정상군보다 유의하게 높았다(P<0.01). IGF-I은 비만군에서 498.1±122.2 ng/mL로 정상군보다 유의하게 높았고(P< 0.05), IGFBP-3도 비만군에서 3,777±471 ng/mL로 정상군보다 유의하게 높았다(P<0.05). 인슐린은 체질량지수(r=0.394), 비만도(r=0.304)와 양의 상관관계를 나타냈다. IGFBP-3는 비만도(r=0.419), 이완기 혈압(r=0.264), 체질량지수(r=0.247)와 양의 상관관계를 보였다. 인슐린저항지수는 체질량지수(r=0.595), 혈중 중성지방(r=0.515), 비만도(0.469)와 양의 상관관계를 나타냈다. 결 론:비만 청소년에서 혈중 인슐린, 인슐린저항지수, IGF-I, IGFBP-3가 증가하였다. 청소년 비만에서 이들 검사는 심혈관 질환으로의 진행을 예측하는데 유용하리라 생각한다
소아기 일과성 고포스파타아제혈증(Hyperphosphatasemia)에 대한 임상고찰
권정현 대한소아청소년과학회 2005 Clinical and Experimental Pediatrics (CEP) Vol.48 No.3
Purpose:The aim of study is to investigate the clinical manifestations and the etiology of markedly-elevated serum alkaline phosphatase(ALP) levels in children without accompanying liver or bone disease. Methods:The serum ALP and other biochemical laboratory data of 4,989 patients attending the pediatric department of Ewha Womans University Mokdong Hospital between January 2002 to December 2002 were studied. The subjects' ages ranged from 4 months to 14 years. Among them, serum ALP levels were markedly elevated over 1,000 IU/L in 114 children. Among those 114 children, 97 children without liver or bone disease were reviewed retrospectively. Results:Of the 114 children with serum ALP activity of over 1,000 IU/L, 97(85.8 percent) children had neither liver or bone disease. The average ALP activity level was 1,539±948 IU/L. The male:female ratio was 1:0.7. Forty-four children(45.3 percent) were between 4 months to 1-year-old, 19 children(19.3 percent) were between 1- to 2-year-old. We observed a seasonal clustering of cases in during October with 10 cases(10.2 percent) and in during December with 11 cases(11.3 percent). The most common clinical presentation was respiratory tract infection in 25 cases(26.9 percent), and acute gastroenteritis in 17 cases(17.5 percent). Forty-four cases had follow-up ALP activity level, 1 month later and the activity decreased under 1,000 IU/L in 37 cases(84percent). Conclusion:Hyperphosphatasemia is a benign and transient phenomenon. If there are no clinical and laboratory abnormalities of liver and bone, we suggest monitoring monitor the high serum ALP level 1 month later. If decreased, it seems that it is not necessary for specific examinations to exclude other diseases of malignant condition. 목 적 : 본 연구에서는 간이나 골격계 질환 없이 알카라인 포스파타아제만 증가된 환아들의 임상적 특징을 알아보고 원인과 의의를 알아보고자 하였다. 방 법 : 2002년 1월부터 2002년 12월까지 1년 동안 본원에서 알카라인 포스파타아제를 포함한 생화학 검사를 시행한 4개월부터 14세까지의 소아 4,989명에서 알카라인 포스파타아제가 1,000 IU/L 이상으로 측정된 환자 114명 중 골격계나 간질환이 없었던 환아를 대상으로 하여 의무기록을 이용하여 후향적인 조사를 하였다.결 과 : 알카라인 포스파타아제가 1,000 IU/L 이상으로 측정된 114명 중 97명(85.8%)이 골격계나 간질환 없이 알카라인 포스파타아제가 상승하였으며 남녀 성비는 1 : 0.7로 남아가 많았다. 평균 알카라인 포스파타아제는 1,539±948 IU/L이었으며, 연령 분포는 4개월에서 1세 미만이 44명(45.3%), 1세에서 2세가 19명(19.3%)으로 가장 많았으며, 월별 분포는 9월에서 12월까지 비교적 발병률이 높았다. 동반 질환은 기관지염 및 폐렴, 천식, 크룹 등의 호흡기계 질환이 25명(26.9%), 급성 장염이 17명(17.5 %)으로 가장 많았다. 1개월 후 알카라인 포스파타아제가 추적검사가 시행되었던 44명 중 37명(84%)에서 1,000 IU/L 이하로 떨어졌다.결 론:소아기에 알카라인 포스파타아제 상승하는 것은 골격이나 간의 질환이 없는 경우 비특이적 지표로 생각된다. 일과성 고포스파타아제혈증은 양성적이고 일시적인 현상으로써 임상적으로 간이나 골격계의 이상이 없으며, 1-2개월 후에 다시 검사하여 알카라인 포스파타아제가 감소하는 경우에는, 악성 종양이나 기타 질환을 배제하기 위하여 불필요한 특수 검사들을 시행할 필요가 없을 것으로 보인다.
