본 연구는 메타분석을 통해 예비부모교육 프로그램의 효과에 관한 연구들을 종합하여 체계적인 결과를 도출하는데 목적이 있다. 이를 위해 PICOS 기준에 따라 1996년부터 2021년 6월까지 연구된 국내 석·박사학위 논문 및 학술지 23편을 연구대상으로 선정하였다. 연구의 결과는 다음과 같다. 첫째, 예비부모교육 프로그램의 전체 평균 효과 크기는 0.68로 중간 효과 크기를 나타냈다. 둘째, 운영특성에 따른 평균효과 크기를 살펴보면, 참여대상은 중·고등학생(0.87)이 가장 크고, 다음으로 대학생(0.68), 군인(0.28) 순으로 나타났다. 또한, 프로그램의 총 회기가 12회기 이상이며, 전체 기간이 13주 이상일 경우 평균효과 크기가 가장 컸다. 셋째, 예비부모교육 프로그램의 종속변인을 정보제공, 신념변화(자기 관련, 양육 관련), 기술습득으로 분류하여 분석한 결과, 정보제공(1.00)이 큰 효과 크기로 나타났으며, 기술습득(0.74), 양육(0.63) 및 자기와 관련된 신념변화(0.62)가 중간 효과 크기로 나타났으나, 각 종속변인별 평균효과 크기 차이가 유의미하지 않았다. 이러한 결과를 토대로 향후 연구 및 정책에 대한 제언을 논의하였다. The purpose of this article is to examine studies on the effects of pre-parent education programs and to draw comprehensive and consistent conclusions through meta-analysis. According to the PICOS, 23 studies conducted from 1996 to 2021 were finally selected and meta-analysised. The results of this study are as follows. First, the overall mean effect size of the pre-parent education program was 0.68, indicating a medium effect size. Second, a comparison of the mean effect size by group of participants revealed that the effect size of adolescents(0.87) group was the largest, followed by the group of college students(0.68) and the group of soldiers(0.28). It was also found to be most effective when the total period of sessions was 12 sessions, the total period of program was more than 13 weeks. Third, according to the dependent variable, information offering(1.00) was shown to be of a large effect size, and skill acquisition(0.74) and changes in parenting(0.63) and self-related beliefs(0.62) were shown to be of medium effect size. Suggestions and implications were discussed based on the findings.

This study aimed to enzymatically prepare structured monogalactosyldiacylglycerols (MGDGs) with different hydrophile-lipophile balance (HLB) values for use as emulsifiers. Acidolysis of Perilla frutescens-derived MGDGs with capric acid (10:0) was conducted to obtain structured MGDGs containing 10:0. Lewatit VP OC 1600-immobilized Rhizomucor miehei lipase was used as the biocatalyst. Structured MGDGs (HLB value=2.95-7.17) containing 13.0-70.6 mol% 10:0 were obtained from P. frutescens MGDGs (HLB value=1.93). A quadratic regression equation (R²=0.920) to predict the 10:0 content of the structured MGDGs under the given conditions was established using response surface methodology. Using a linear regression equation (R²=0.999) to predict the HLB value by 10:0 content, structured MGDGs containing 27.1-54.6 mol% 10:0 were predicted to have an HLB value of 4-6, indicating their potential applicability as hydrophobic emulsifiers. Structured MGDGs with a purity of ∼43% w/w were obtained from the reaction products using silica column chromatography.
Exploring Media Literacy: Enhancing English Oral Proficiency and Autonomy Using Media Technology
( Sohee Kim ) 글로벌영어교육학회(구 호남영어교육학회) 2018 Studies in English education Vol.23 No.2
Electronic media learning environments afford English language learners more opportunities to use media technology that may require them to attain new media literacy skills. This research examines whether Korean EFL learners’ oral proficiency and autonomy can improve when using media technology. The research involved 62 university students who attended general basic-level English programs. In order to investigate their improvement, this research assessed participants’ speaking development across four digital storytelling tasks and their autonomy and attitudes towards using ICT programs and movie clips via questionnaires during an 8-week period. The participants practiced individual storytelling and created stories using three different ICT programs―Vocaroo, VoiceThread, and TTS―along with their selected movie clips to speak about the given topics in and out of the classroom. The results revealed that participants were able to improve their oral proficiency in terms of discourse based on their critical thinking about the chosen media. They also felt using ICT programs positively affected autonomy development although there was no statistical significance of correlation with their computer proficiency. Overall, participants’ computer skill to utilize media technology was an important factor for oral proficiency development. Additionally, an instructor’s feedback was significant to speaking improvement.

In previous reports, bisphenol A (BPA) exposure affects reproductive function in Drosophila melanogaster females. To test the maternal effect of BPA exposure on fly reproductive function, F0 mothers were exposed to 0, 0.1, 1, and 10 mg/L of BPA and the fecundity in F1 and F2 generations were checked. In this experiment, 1 and 10 mg/L BPA significantly decreased the fecundity of F1 females. Moreover, 0.1 and 1 mg/L BPA substantially reduced egg production in the F2 generation. These results suggested that maternal exposure to BPA at enviromentally relavant concnetrations reduces reproductive function in Drosophila melanogaster females and that this effect is transgenerational.

산업, 의료, 금융 등 다양한 분야에서 인공지능을 활용한 예측 및 진단이 늘어나면서, 인공지능의 내부 작동원리를 설명하는 연구에도 관심이 높아지고 있다. 이미지 데이터에서 중요 입력 특징점을 시각화하는 기존 연구들과 다르게, 본 논문에서는 시계열 데이터의 은닉 노드를 시각화하여 심층신경망 내부의 작동원리를 설명한다. 본 논문은 은닉 노드의 시각화를 쉽게 하도록 가중치 행렬(weight matrix)을 기준으로 은닉 노드를 군집화하여 패턴을 파악하였다. 이를 통해 심층학습 모델의 작동원리를 설명할 뿐만 아니라, 사용자 수준에서 시계열 데이터에 대한 이해를 높일 수 있었다. Globally, the use of artificial intelligence (AI) applications has increased in a variety of industries from manufacturing, to health care to the financial sector. As a result, there is a growing interest in explainable artificial intelligence (XAI), which can provide explanations of what happens inside AI. Unlike previous work using image data, we visualize hidden nodes for a time series. To interpret which patterns of a node make more effective model decisions, we propose a method of arranging nodes in a hidden layer. The hidden nodes sorted by weight matrix values show which patterns significantly affected the classification. Visualizing hidden nodes explains a process inside the deep learning model, as well as enables the users to improve their understanding of time series data.

Most Internet users permit the usage of cookie without knowing the fact. They also overlook that Internet speed gets faster by using cookie. Every web page surfing on the Internet is represented as HTML document which is open to everyone. Cookie and HTML document allow anyone to access to web server's source code and use that as a tool of tracking or hacking. This paper suggests the encryption of HTML document using cookie as a key, which we should use inevitably. We limit the range of this study especially to web server and client and web server transmits encrypted HTML document to the client.

본 연구의 목적은 노인의 밸런스 능력의 차이가 장애물 넘기 동작에 미치는 영향에 대해 검토하는 데 있다. 피험자는 눈뜨고 한발서기가 120초 동안 가능한 여성노인 8명 (Possible group; PG) 과 불가능한 여성노인 8명 (Impossible group; IG)을 대상으로 했다. 5 m의 보행로의 중앙에 20 cm 높이의 장애물을 설치하고 가능한 한 빨리 걷도록 지시했다. 평가국면은 장애물을 넘기 직전의 Initial contact phase와 넘을 때의 Swing phase (Lead limb 와 Trail limb)로 하고, 평가변수는 각도에 관한 7개의 변수 및 높이(지면에 대한 거리)에 관한 4개의 변수를 선택했다. Initial contact phase에서는 장애물이 없는 조건에 비해 발 앞꿈치의 높이가 낮았다. 즉, 노인들은 발 앞꿈치를 낮게해서 장애물 넘을 준비를 했던 것으로 보여 진다. Swing phase of lead limb에서는 발목, 무릎 및 고관절굴곡, 흉복부 측굴 및 고관절 내전각도에서, 그리고 무릎, 발앞꿈치, 허리의 높이에서 장애물간 주효과가 나타났다. 허리의 높이는 IG에서, 그 외 다른 평가변수는 두 그룹 모두에서 장애물 조건이 없는 조건에 비해 컸다. Swing phase of trail limb에서는 흉부 회선각도에서 유의한 상호작용이 나타났으며 그 외의 대부분의 평가변수에서 장애물간 주효과가 나타났다. 흉부 회선각도는 장애물 조건에서 PG가 IG에 비해 높은 값을 보였다. 이상으로 밸런스 능력이 뛰어난 노인은 보행 중 한발지지 시에 밸런스 유지를 쉽게 할 수 있었기 때문에 보다 안정되게 큰 보폭을 이용하여, 빠른 속도로 장애물을 넘을 수 있었지만, 밸런스 능력이 부족한 노인은 천천히 작은 보폭을 이용하는 대신 장애물을 넘기 위해 몸의 중심이나 어깨의 위치를 높게 하는 특성을 보였다.

Origin of Red imported fire ant (RIFA : Solenopsis invicta) is Central America, a tropical climate region. It has settled in the invasive area, causing various problems. In recent, Solenopsis invicta were discovered in Busan in 2017 and then in 2018 at a construction site in Busan, Pyongtaek, Incheon and in Daegu. This study aims to confirm the origin of invasive colonies of Solenopsis invicta. We tried to test previously developed microsatellite markers so that we establish the tracing protocol for molecular epidemiology of RIFA. We justified 66 microsatellite markers already developed using DNA from the RIFA found in Incheon Harbor. As results, 30 markers were selected to facilitate amplification and fragment analysis.
