e-Learning 기반 교원 원격연수에 영향을 미치는 요인들에 대한 체계적인 연구가 필요하다. 본 연구는 교원 원격연수 프로그램을 개발·적용한 후, 학습자의 배경변인과 학습전략이 학업성취도와 교육만족도에 미치는 영향을 분석하였다. D광역시 교육연수원의 60차시 연수과정을 이수한 중·고등학교 교사 190명을 연구대상으로 하였다. 연구 결과, 학습자의 배경변인에 따른 학업성취도와 교육만족도의 차이에서는 여교사의 학업성취도가 남교사보다 높고 자발적인 연수 참여 여부가 학업성취에 중요한 영향 변인으로 나타났다. 온라인 학습전략에 따른 학업성취도와 교육만족도 분석에서는 자기조절 학습전략이 교육만족도와 학업성취도에 가장 큰 영향을 미치는 것으로 확인되었고 온라인 학습 태도, 시간관리, 정보해독처리전략이 교육만족도에 유의미한 영향을 미치는 변인으로 확인되었다. It is necessary to do systematic researches on factors effecting online teacher training. This study is to develop and apply an online teacher training program, and to analyze learning achievement and educational satisfaction according to learners` background variables and learning strategies in e-learning environment. The subjects were 190 secondary school teachers who had completed a online program of a teacher training center in D city. The results showed that female teachers and teachers who voluntarily attended the program had higher achievement. In the analysis of academic achievement and educational satisfaction according to learners` learning strategies, self-regulated strategies had the highest effect on both variables and online learning attitudes, time management, information interpretation were the variables which had significant effect on educational satisfaction.

최근 수도권 중심의 생활권역 확장과 대도시로의 인구 집중으로 도시 내의 교통 혼잡이 지속적으로 증가하고 있다. 도심지의 땅값 상승과 한정된 부지로 인해 새로운 도로 건설은 불가능하게 되었고, 데이터 기반의 효율적인 도로 운영의 중요성이 점점 부각되고 있다. 효율적인 도로 운영을 위해서는 교통상황의 변화에 따른 적절한 TOD 시간분할과 TOD 시간분할을 통한 최적의 신호 운영 방안이 필수적이다. 본 연구에서는 최적의 TOD 시간 분할을 위해 연속된 교차로에서 수집된 교통량과 속도 데이터에 시계열 데이터의 군집 분석을 위한 동적 타임 워핑 모델을 적용하였다. 시간 분할을 위해 활용된 데이터별 군집의 특성을 분석하여 최적의 신호 운영 시나리오를 구성하기 위한 시간 분할 방법론을 제안하고자 한다. Recently, traffic congestion in the city is continuously increasing due to the expansion of the living area centered in the metropolitan area and the concentration of population in large cities. New road construction has become impossible due to the increase in land prices in downtown areas and limited sites, and the importance of efficient data-based road operation is increasingly emerging. For efficient road operation, it is essential to classify appropriate scenarios according to changes in traffic conditions and to operate optimal signals for each scenario. In this study, the Dynamic Time Warping model for cluster analysis of time series data was applied to traffic volume and speed data collected at continuous intersections for optimal scenario classification. We propose a methodology for composing an optimal signal operation scenario by analyzing the characteristics of the scenarios for each data used for classification.

이 연구는 청소년을 대상으로 개발된 마음그램 에비척도(2021)의 타당도를 재검증하는 것이다. 안관수(2021)가 개발한 마음그램 예비척도는 7개의 요인 가운데 일부 문항에 오류가 발견되었다. 이 연구는 이러한 점을 보완하기 위해 개발된 마음그램 예비척도의 요인구조와 문항의 구성을 분석하고 신뢰도와 타당도를 재검증하는 데에 목적이 있다. 탐색적 요인분석과 확인적 요인분석에서 사용한 표본은 선행연구에서 수집한 중ㆍ고등학생 280명의 자료를 토대로 검증하였으며, 준거타당도에서는 충남, 전북 지역 중ㆍ고등학생 312명을 대상으로 설문 후 공인타당도를 실시하였다. 그 결과 요인구조는 7요인(인간존중/용서/자기통제/의지력/자율성/수용/이타행동)으로 31문항이며, 요인모형의 적합도는 수용 가능한 것으로 나타났다. 공인타당도 결과 마음그램 척도는 무조건적 자기수용척도, 단축형 자기통제척도, 심리적 안녕감척도, 관용성척도와 유의미한 상관이 있는 것으로 나타났다. This study retests the validity of the preliminary Maumgram scale developed for adolescents. Errors were found from a few of items among seven factor of preliminary Maumgram scale developed by An Gwansu(2021). To correct errors, it aims to retest the reliability and the validity of the scale, by analyzing the factorial structure and the composition of items in it. It examined the sample used for both exploratory and confirmatory factor analysis based on the data of 280 junior high and high school students, collected by a previous study, and tested the concurrent validity, among criteria-related validity, by administering questionnaires to 312 junior high and high school students in Chun-gnam and Jeong-buk. The findings show that the factor structure consists of seven factors (31 items) such as respect for persons, forgiveness, self-control, willpower, autonomy, acceptance and altruism, and the validity of the factor model is acceptable. The concurrent validity was tested to show that the Maumgram scale has significant correlations with the scales of Unconditional self-acceptance, Brief self-control, Psychological well-being, and Tolerance.

2세 여아에서 성장 부진과 다리 통증을 동반한 1형 고셔병 증례

박예슬,황재연,황은하,전종근,이범희,유한욱,김유미,Park, Yesul,Hwang, Jae-Yeon,Hwang, Eun Ha,Cheon, Chong Kun,Lee, Beom Hee,Yoo, Han-Wook,Kim, Yoo-Mi 대한유전성대사질환학회 2017 대한유전성대사질환학회지 Vol.17 No.2

고셔병은 리소좀축적병으로 lysosomal hydrolase glucocerebrosidase 결여로 간비장비대, 골격계 증상, 빈혈, 혈소판 감소증의 증상을 나타내는 드문 상염색체 유전 질환이다. 본 증례에서는 2세 여아에서 간비장비대, 다리 통증, 성장부진이 관찰되어 시행한 단순 방사선 촬영 검사에 Erlenmeyer flask 변형을 확인하여 고셔병을 의심하였고 효소 분석 및 유전자 검사를 통해 확진하였다. 환아에서 한국인 비신경형 고셔병에서만 관찰되는 G46E 돌연변이를 확인하였고 1년 간의 효소 대체 요법을 통해 성장, 혈액학적 지표, 간비장비대 및 골증상의 호전을 확인하였기에 본 증례를 보고하는 바이다. Gaucher disease (GD) is caused by the deficiency of glucocerebrosidase. In pediatric patients with GD, especially Type I GD, enzyme replacement therapy (ERT) can reduce the hepatosplenomegaly and improve the hematologic finding and growth velocity. Herein, we report a 2-year-old girl with Type I GD presented with hepatosplenomegaly, bone pain and growth retardation. A 2 year-old-girl was referred to our hospital due to severe hepatosplenomegaly and growth retardation. She suffered from both leg pain and chronic fatigue. Simple x-ray showed widened distal long bones like that of an 'Erlenmeyer flask' which is associated with GD. The laboratory test showed anemia and thrombocytopenia. The enzyme activity was markedly reduced and the direct sequencing of the GBA gene showed the compound heterozygous mutations, p.G46E and p.L444P. As the G46E have been considered as the protective gene against neuronopathic genotype, we could assess the Type I GD in this patient. After one year of ERT, the growth velocity became 11 cm per year. Bone pain and fatigue disappeared. The volume of liver and spleen was reduced from $683cm^3$ and $703cm^3$ to $590cm^3$ and $235cm^3$, respectively. Although GD is an extremely rare disease in Korea, growth retardation and bone pain in children are the important signs which lead to early detection of GD and a simple radiologic finding is helpful to assess the GD at outpatient clinic. We highlight that the early diagnosis and early ERT is important for good growth and outcome for pediatric patients with GD.
